Background: Diabetes mellitus patients are more likely to undergo nontraumatic foot or leg amputations because they have decreased circulation to the feet or reduced sensation. This condition may cause ulcerations, infections, and delayed wound healing, leading to amputations. Adequate knowledge and practices regarding foot care will be vital in the prevention of diabetic foot complications. Hence, this study aimed to determine the level of knowledge and practices of foot care among diabetes mellitus patients attending a rural primary health center in Belagavi-South India. Materials and Methods: A cross-sectional study was conducted in the rural field practice area of J.N. Medical College, Belagavi, for 7 months (November 2019 to May 2020). A pretested questionnaire was administered to 461 diabetes patients attending the health center. A written informed consent was obtained from each participant. They were interviewed with a questionnaire consisting of 15 “yes” or “no” questions, each on foot care knowledge and practice. Results: The mean age of the study participants was 50.28 ± 9.48 years. The mean duration of diabetes was 10.69 ± 7.09 years. Majority, i.e., 296 (64.2%) participants showed satisfactory knowledge and 293 (63.6%) showed satisfactory practice. Only 97 (21%) had poor knowledge, 90 (19.5%) had poor practice, 68 (14.8%) patients had good knowledge, and 78 (16.9%) had good practice about diabetic foot care. Conclusions: The low level of knowledge and practice in patients with diabetes regarding foot care necessitates an educational program to increase awareness related to foot complications of diabetes, thereby motivating diabetic patients to incorporate foot care practices in their day-to-day routine.

Background: Nausea and vomiting is a common complication after gynecological surgeries, especially laparoscopy, which can lead to discomfort and restlessness in the patients. The aim of the study was to compare the effect of ondansetron–dexamethasone and metoclopramide–dexamethasone on postoperative nausea and vomiting following gynecological laparoscopy. Materials and Methods: In this double-blind clinical trial, 68 females scheduled for gynecological laparoscopy and age range of 18–40 years were randomly divided into two groups. Group OD received ondansetron 4 mg plus dexamethasone 8 mg and group MD received metoclopramide 10 mg plus dexamethasone 8 mg, 15 min before the end of surgery. The incidence of nausea and vomiting and need for rescue medication was assessed during the recovery period, as well as at 2, 4, 6, 12, and 24 h after surgery. The data were analyzed using STATA software version 12 and a significance level of <0.05 was considered in this research. Results: The incidence of nausea in ondansetron and metoclopramide groups was 23.3% and 33.3%, respectively, and the frequency of vomiting was 10% and 16.6%, respectively, which showed no significant difference (P > 0.05). The highest incidence of nausea and vomiting in patients belonged to the metoclopramide group inside 4–6 h after surgery. Conclusion: Our study showed that no significant difference was observed in the incidence of nausea and vomiting between ondansetron–dexamethasone and metoclopramide–dexamethasone groups following laparoscopic gynecological surgery; however, the number of patients with nausea and vomiting was lower in the ondansetron–dexamethasone group.

Background: Migraine, one of the most common headaches in children, has a significant impact on children and their family's quality of life (QoL). There are two approaches for controlling migraine headaches preventative and controlling acute attacks. Several drugs have been used for this purpose, and tricyclic antidepressants were at the top. Amitriptyline has shown not only a desirable effect on controlling the headaches but also some adverse side effects. Recently, finding effective drugs with fewer side effects, become more critical. Among them, nutraceuticals were one of the promising ones. Materials and Methods: In this randomized clinical trial on 72 patients aged 5–15 years old with diagnosis of migraine based on the International Headache Society criteria, we compare the effectiveness of coenzyme Qten on frequency, duration, and severity of childhood migraine. For comparing the QoL, we used the International PedMIDAS questionnaire. Results: Coenzyme Qten showed good therapeutic effects in children, especially in long-term use; however, amitriptyline showed more rapid response. After 3 months of treatment, clinical outcomes in the two groups did not significantly differ from each other. Similarly, Children's QoL increased in the same way. There are more reported side effects in children using amitriptyline compared to coenzyme Qten. Conclusions: According to results, Co-enzyme Q10, with fewer side effects and comparable therapeutic effects, especially in the long term, could be a good drug for prophylactic treatment of migraine headaches.

Background: The present study investigated the prevalence of illness anxiety disorder and its relationship with social health in the elderly population. Materials and Methods: This cross-sectional study was conducted on 400 elderly people in Isfahan referred to the educational health service in 2020. In addition to demographic characteristics, they answered the 36-item Evans hypochondriasis questionnaire and the 28-item social health questionnaire. Results: Four hundred elderly participants with a mean age of 68.1 ± 6.6 (range: 60–89) were included in the study. One hundred and ninety-nine (49.8%) were female and 201 (50.3%) were male. Only 24.3% of the geriatrics were in the healthy group and 21.2% in the borderline category. Seventy-two of the geriatric population (18%) had poor social health and 299 of this population (74.8%) had moderate social health, and the social health status of 29 elderlies (7.3%) was favorable. There was an inverse relationship between hypochondriasis score and total social health score and its dimensions (P < 0.05). Conclusion: High prevalence of hypochondriasis was observed in the geriatrics compared to global studies. Most of the elderly population had moderate social health. Gender and education do not affect hypochondriasis and social health in the elderly. People with higher social health scores were clearly less likely to get hypochondriasis. Therefore, by improving the various dimensions of social health of the geriatrics, we can help reduce the prevalence of hypochondriasis in this age group.

Background: Patient management after bariatric surgery is important in controlling patients' diabetes and recurrence prevention. This study aimed to meet the medical managements of patients with diabetes 6 months after the bariatric surgery. Materials and Methods: This cross-sectional study was performed on 77 type 2 diabetes patients' candidates for bariatric surgery (Roux-en-Y [RYGP] and Omega). Postoperative implementation protocol was one-third of insulin for patients taking long-term insulin and the discontinuation of medications for patients of oral antidiabetic agents. Blood glucose (BG) level was checked regularly by the patients at home and the necessary medical management was applied. The weight, BG and HbA1C levels, and use of oral antidiabetic agents and insulin were assessed and recorded before 1, 3, and 6 months after the surgery. Results: BG levels and HbA1C percentage in the 1^st, 3^rd, and 6^th months after the intervention in Omega group were significantly lower than RYGB group (P value < 0.05). At 1 and 3 months after surgery, the mean insulin dose received by the Omega and RYGB groups was reduced to <30 units/day and 10 units/day, respectively, following the management protocol in this study. Moreover, 23.1% and 7.7% of patients in RYGB group and 12.1% and 3% of patients in Omega group took oral antidiabetic agents 1and 3 months after surgery, respectively. Insulin and oral antidiabetic agents were completely discontinued 6 months after the surgery. Conclusion: The long-term management and support of the patients by the implementation of a standard protocol after surgery are of great significance in obtaining the optimal outcome after bariatric surgery.

Background: The exact prevalence of hypertension in children surviving acute lymphoblastic leukemia (ALL) has not been fully estimated. The aim of this study was to investigate the prevalence of arterial hypertension (AH) and to determine the risk factors for the development of AH in children surviving ALL with current treatments. Materials and Methods: A total of 150 patients (84 males, 66 females, with an age range of 1–16 years) were included in the study. Demographic and clinical information of patients were initially recorded. Hypertension is defined as average systolic blood pressure (BP) and/or diastolic BP that is greater than the 95^th percentile for gender, age, and height. Results: The mean age at the assessment of BP was 11.3 and 9.8 years in the ALL and control group, respectively. A total of 20.6% of survivors of ALL and 10% of controls had high BP. Most patients in both groups had normal BP (65.3% patients in ALL group and 75.4% subjects in the control group). The number of patients with hypertension was significantly higher in ALL patients as compared with the control group (P = 0.026). Conclusion: The prevalence of AH in children surviving ALL is higher than in children in the general population, which emphasizes the need for regular monitoring of BP in children surviving ALL and intervention in the lifestyle of this population. Careful follow-up of BP status is warranted for long-term survivors of childhood cancer.

Background: The assessment of the emotional consequences of having a spinal deformity and orthotic management in people with idiopathic scoliosis is essential. This study was aimed to translate and culturally adapt the Bad Sobernheim Stress questionnaire (BSSQ-Brace) for Iranian adolescents with idiopathic scoliosis using thoracolumbar orthoses. Materials and Methods: The BSSQ was translated into Persian according to a standard guideline. The Persian BSSQ-Brace was completed by 55 Iranian subjects with spinal deformities who agreed to participate in this research. The validity was determined by correlating the Persian BSSQ-Brace questionnaire (BrQ) and the revised Scoliosis Research Society-22 patient questionnaire (SRS-22r). To assess test-retest reliability, all participants completed the BSSQ-Brace twice, with a gap of 1-week. Intraclass Correlation Coefficient and Cronbach's alpha were measured to report reliability. Results: All population revealed items in the Persian BSSQ-Brace were easily understood, and there was no difficulty completing them. The psychometric properties of the Persian version of BSSQ-Brace demonstrated excellent test-retest reliability (interclass correlation coefficient = 0.94), excellent internal consistency (Chronbach's alpha = 0.94), and high construct validity with SRS-22r (r = 0.74). Conclusions: The Persian BSSQ-Brace is a reliable and valid instrument to assess the emotional domains in subjects wearing a spinal orthosis.

Background: The current study aims to assess the effects of the large simple renal cyst (SRC) surgery on renal function for the first time. Materials and Methods: This case-series study included 22 patients with larger than 50 mm single SRC who underwent laparoscopic cyst unroofing surgery. Twenty-four-hour urinary protein, creatinine, and volume along with plasma creatinine and estimated glomerular filtration rate (GFR) were measured in patients before and 1 month after surgery. Patients underwent abdominopelvic computed tomography-scan without contrast and parenchymal thickness diameter adjacent to the cyst was measured before and after surgery. Results: Mean age and weight of patients were 52.2 ± 8.9 years and 77 ± 10.9 akg, respectively. There was no significant difference between plasma creatinine and GFR before and after surgery (P = 0.25 and 0.37, respectively). Twenty-four-hour urinary volume, creatinine, and protein before and after surgery revealed no significant changes (P = 0.37, 0.08, and 0.31, respectively). The mean improvement of parenchymal thickness diameter after surgery was 10.4 ± 0.7 mm which was statistically significant (P = 0.001). However, it was not correlated with the mean estimated GFR change (r = 0.349, P = 0.13). Conclusions: Although laparoscopic unroofing of renal cyst recovered renal parenchymal thickness noticeably, it did not improve renal function significantly; therefore, the latter factor lonely should not be considered a reason for surgery decision. Observation can be chosen as a safe treatment strategy in large SRCs without concern about renal function.

Background: Early and cost-effective diagnosis and monitoring of the infection caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are critically important to anticipate and control the disease. We aimed to set up a SYBR Green-based one-step real-time polymerase chain reaction (PCR) as a lower-cost alternative method to detect the virus. Materials and Methods: An in-house SYBR Green-based PCR assay targeting the envelope (E) and RNA-dependent RNA polymerase (RdRp) genes, was set up to diagnose the infection, and was compared with the reference probe-based PCR method. Results: When the commercial probe-based assay was considered as the reference method, SYBR Green-based PCR had a slightly lower sensitivity (81.98% and 86.25% for E and RdRp targets, respectively) and a good specificity (100% and 94.44% for E and RdRp targets, respectively). For both gene targets, three different melting temperature (Tm) patterns were found in the PCRs of the nasopharyngeal/oropharyngeal swab samples, but no size polymorphism was seen in agarose gel electrophoresis. Conclusion: Further studies to improvement of the assay are needed to make it an inexpensive and reliable tool for the diagnosis of COVID-19.

Background: The axillary reverse mapping (ARM) technique identifies and preserves arm nodes during sentinel lymph node biopsy (SLNB) or axillary lymph node dissection (ALND). Here, we aimed to investigate the prevalence of lymphedema following ARM. Materials and Methods: This is a clinical trial that was performed in 2019-2020 in Isfahan on patients with breast cancer in the early stages. Demographic and initial information of all cases including age and body mass index (BMI) was collected. Patients were then underwent SLNB ± ALND associated with ARM and were followed up for lymphedema every 6 months to a year. The occurrence of lymphedema was assessed. Results: By evaluating data of 102 patients, we found that 10 patients (9.8%) had lymphedema and patients with lymphedema had significantly higher age (P = 0.004), higher BMI (P = 0.001), larger tumor size (P = 0.018), and longer surgery duration (P < 0.001). The frequency of menopausal women was higher in patients with lymphedema compared to other cases (P = 0.001). Conclusion: The prevalence of lymphedema was high among patients undergoing ARM that was associated with factors including higher age, higher BMI, prolonged surgery duration, larger tumor size, and menopause. We believe that further comparative studies should be conducted on this issue.

Background: Knee osteoarthritis (KOA) may considerably change the gait parameters, including the gait variability patterns. Uncontrolled manifold (UCM) analysis has been used to evaluate the relationship between motor control and gait variability as a useful index for assessing the multi-segmental movements' coordination during walking. To our knowledge, no research has evaluated the alterations in the gait kinematic parameters during normal and narrow path walking in individuals with KOA as compared to asymptomatic people. Materials and Methods: In this cross-sectional study, individuals diagnosed with mild to moderate medial KOA and asymptomatic people will walk at their comfortable preferred speed on a treadmill. A motion capture system will be used to record at least 50 successful gait cycles. The kinematic variability of joints during gait will be analyzed using UCM, with the center of mass (COM) displacement considered as the performance variable. The primary outcome measure will be the lower limb synergy index. Variability of the COM displacement and changes in angles and angular velocities of lower extremity joints will be assessed as the secondary outcomes. Results: The results of this protocol study provide information on the lower limb kinematic synergy during gait on normal and narrow paths for individuals with KOA and asymptomatic controls. Conclusion: This information will help the researchers and clinicians understand KOA patients' gait variability characteristics more deeply. Moreover, it may lead to an enhanced evidence-based approach for clinical decision-making concerning improving gait stability and decreasing the falling risk in these people.

Background: Severe varus deformity of the knee poses a technical challenge in balancing the flexion–extension gaps. The use of a varus–valgus constrained prosthesis is a solution to achieve coronal plane stability. The results of constrained condylar knee (CCK) implants in primary total knee arthroplasty are not well known. This study aims to compare the functional outcomes of posterior-stabilized (PS) and CCK implants for primary arthroplasty of the varus knee. Materials and Methods: Twenty patients with bilateral severe osteoarthritis and genu varum of more than 10° were enrolled in this study. One knee was randomly implanted with a fixed-bearing PS implant, whereas the other was implanted with a CCK prosthesis. Pre- and postoperative Knee Society Score (KSS) and Oxford Knee Score (OKS) questionnaires were completed, and knee flexion was measured and compared. Results: The patients were followed for 32 months on average (24–36 months). On the KSS and OKS, both the groups improved significantly, but the difference between them was not statistically significant. Postoperative knee flexion was also not different between the two groups. Furthermore, 18 patients could not distinguish the difference between the two prostheses, whereas two patients preferred the PS one. Conclusion: We demonstrated that a PS prosthesis can achieve comparable functional results to the CCK one in the short term.

Background: Carvacrol is a natural phenolic monoterpene with anti-inflammatory and antioxidant bioactivities. Neuroinflammatory and oxidative stress responses play a crucial role in the pathogenesis of Alzheimer's disease. The present study examined the effect of carvacrol on brain tumor necrosis factor-alpha (TNF-α) level and oxidative stress as well as spatial learning and memory performances in lipopolysaccharide (LPS)-exposed rats. Materials and Methods: The rats were treated with either carvacrol (25 and 50 mg/kg) or Tween 80 for 2 weeks. Thereafter, LPS (1 mg/kg) or saline was intraperitoneally administered on days 15–19, 2 h before Morris water maze task, and treatments with carvacrol or Tween 80 were performed 30 min prior to behavioral testing. The level of TNF-α, lipid peroxidation, and total thiol concentration were measured in the hippocampus and cerebral cortex at the end of the experiment. Results: It was found that LPS-exposed rats exhibited spatial learning and memory dysfunction, which was accompanied by increased TNF-α level and lipid peroxidation, and decreased total thiol concentration in the hippocampus and/or cortex. Moreover, treatment with carvacrol at a dose of 25 mg/kg attenuated learning and memory impairments, decreased TNF-α and lipid peroxidation level in the hippocampus and cortex, and increased total thiol concentration in the cortex. Conclusion: Carvacrol exerts neuroprotective effects against LPS-induced spatial memory deficits through attenuating hippocampal TNF-α level and oxidative stress in rats.

Also known as intravascular papillary endothelial hyperplasia, Masson's tumor is a relatively rare soft-tissue vascular tumor that usually arises in the hand. Felon is an abscess formation in the distal phalanx that usually occurs following a penetrating microtrauma. We present a 30-year-old patient who was referred to our clinic with a palpable mass in the distal phalanx of the index finger after a needle stick injury. At first, the lesion was treated as a felon but finally and after treatment failure, a complete reevaluation revealed the lesion to be a Masson's tumor of the distal phalanx.

Ataxia–telangiectasia (AT) is a type of primary immunodeficiency characterized by an autosomal recessive mode of inheritance and usually presents with progressive cerebellar ataxia in early life. This complex disease is associated with humoral and cellular immune dysfunction and other features including characteristic oculocutaneous telangiectasia and increased predisposition to cancers, particularly lymphoma and leukemia. An 11-year-old Iranian girl presented with primary immunodeficiency and was diagnosed as having AT according to her clinical manifestations and molecular findings. She had a history of two types of non-Hodgkin's lymphoma and showed spontaneous regression of her diffuse large B-cell lymphoma without any specific treatment. Gene mutations and dysfunction in patients with AT result in different manifestations including abnormal development of the thymus, immunodeficiency, increased susceptibility to malignancies, and increased radiosensitivity. No standard treatment is available for these patients. The use of immunotherapeutic strategies in patients with primary immune deficiency disease-associated tumors is potentially important.

Background: One of the basic practices in the field of waste management is the collection and treatment of leachate. Leachate from municipal waste due to high chemical oxygen demand (COD) and dark color is a potential pollutant of the environment, which causes a lot of problems in the absence of treatment and direct discharge to the environment. This study aimed to determine the efficiency of ultrasonic process in combination with coagulation and flocculation process using sodium ferrate in COD and color reduction. Materials and Methods: In this experimental study, all experiments were performed in batch conditions and with changing process variables such as pH and sonication time, and the effect of three parameters, including ultrasonic reaction time (15, 30, and 45 min), pH (2, 4, 5/5, and 7), and coagulant dosage (from 1 to 150 g/l) on the COD reduction and color removal, was evaluated. Coagulant concentration and then the removal efficiency of COD and color were analyzed by ANOVA using SPSS 18. Results: The COD reduction and color removal were 87.05% and 88.6% in optimal condition (using 120 g/L of sodium ferrate at pH 5.5), with coagulation/flocculation, after ultrasound (15 min). Ultrasound (15 min) + sodium ferrate (without coagulation/flocculation) achieved 46.25% of COD reduction and 90.35% of color elimination, whereas the ultrasonic process alone allowed removing the COD and color in the leachate by less than 50%. Conclusion: The results indicate that C–F followed by ultrasonic can be used to efficiently reduce the organic matter and color from municipal waste leachate, and it would be an ideal option for leachate treatment.

Background: Oral candidiasis (OC) has been noticed as a common mucous membrane infection in immunocompromised patients such as that diabetes. This study, focused on the genotyping of Candida albicans and enzymatic activities of Candida species recovered from oral mucosa among diabetes patients and healthy individuals. Materials and Methods: Specimens were obtained from oral mucosa of One-hundred and sixty patients with type 2 diabetic and 108 healthy individuals. All isolates were definitely identified by ribosomal DNA (rDNA) gene sequencinghHydrophobicity, hemolytic activities of Candida species and genotypes of C. albicans were determined through polymerase chain reaction (CA-INT). Results:, Eighty eight (55%) samples out of 160, were positive for Candida species in diabetic patients. Moreover, 79.5% (70/88) and 20.5% (18/88) isolates belonged to the C. albicans and non-albicans Candida species respectively. Three genotypes of C. albicans have recovered in diabetic patients: genotype A (71.42%), B (21.42%), and C (7.14%). In healthy individuals, 42.6% (46/102) Candida species recovered from oral cavity, with the highest prevalence of genotype A (76.6% of C. albicans). Additionally, hydrophobicity and hemolytic activities from Candida species were significantly greater in diabetes patients than healthy nondiabetic subjects. Conclusion: Collectively, C. albicans was the most causative agent isolated from diabetes patients and non-diabetes healthy individuals. Genotype A, as the most remarkable genotype, should be mentioned in both groups. Higher potential hydrophobicity and hemolytic activities of Candida species in diabetic patients compared to healthy cases suggest these features triggering pathogenicity of OC in diabetes patients.

Background: The aim of this study was to compare the effect of adding oral clonidine to standard treatments on pain intensity in patients with acute renal colic. Materials and Methods: This is a randomized clinical trial that was performed in 2020 in Isfahan. The study population consisted of 200 patients with renal colic. Pain of the patients was assessed using Visual Analog Scale. Patients were then randomized into 4 groups of 50 patients. Group A received 0.1 mg/kg morphine and clonidine tablets (0.2 mg). Group B received morphine and placebo. Group C received 30 mg ketorolac and clonidine tablets. Group D received 30 mg ketorolac and placebo tablets. Pain of patients was assessed. 0.05 mg/kg morphine was administered and repeated every 40 min if the pain was not reduced. Results: Our data showed that there was a significant difference between pains of patient by the time of admission in groups (P = 0.04). However, no significant differences were observed between pains of patients in different measuring times (P > 0.05). Using general linear model, we showed that the decreases in pain scores of each group were significant (P < 0.05) but there were no significant differences in pains of patients in different measuring times (P > 0.05). Our data showed that Group A and Group C had lowest frequencies of morphine administrations while Groups B and D had the highest frequencies (P < 0.001). Conclusion: We showed that administration of clonidine in patients with renal colic resulted in better pain control and lower morphine injections.

Background: Ectopic pregnancy (EP) occurs in 1% of pregnancies, and may seriously effects on women's health and future fertility so this study aimed to compare the results of hysterosalpingography (HSG) after treatment of EP by laparoscopy, laparotomy, and methotrexate (MTX) therapy. Materials and Methods: This was a clinical trial study was done on 112 EP women with treatment indication referred to Isfahan Al-Zahran and Shahid Beheshti Hospitals from 2017 to 2018. They were divided into 33 populated groups of laparoscopic salpingostomy, laparotomy and MTX. Then patients of three groups underwent HSG 3 months after intervention. The factors such beta human chorionic gonadotropin (β–hCG) (mIU/mL), size of EP (mm), infection, hospital length of stay (LOS), and tubal patency were recorded and compared between the groups. Results: There were no significant differences between groups for age, body mass index, β–hCG, Size of EP, and hospital LOS (P > 0.05). The infection was more frequent in laparotomy group with no significant difference among three groups. The infection rates were 9%, 12%, and 6% for MTX, laparotomy, and laparoscopy arms, respectively. Between the three groups tubal patency as primary outcome had higher frequency than laparoscopy group, although, the difference was not statistically significant (P = 0.595). Conclusion: Although infection was more in laparotomy and that tubal patency was more within 3 months in laparoscopy and MTX, there were no statistically significant differences in the results of laparoscopy, laparotomy, and MTX in HSG results.

Background: CA1, as a major structure involved in learning and memory, has been shown to be affected by tramadol addiction. Both orexin and endocannabinoid receptors express in CA1 and play an important role in drug dependency. The aim of this study was to evaluate the modulatory effects of orexin-2 (OX2R) and endocannabinoid-1 (CB1R) receptors on neuronal activity in CA1, in response to tramadol in rats. Materials and Methods: Male Wistar rats were divided into 8 groups (n = 6–7); saline-dimethyl sulfoxide (DMSO), tramadol-DMSO, saline-TCS-OX2-29, saline-AM251, tramadol-TCS-OX2-29, tramadol-AM251, saline-TCS-OX2-29-AM251, tramadol-TCS-OX2-29-AM251. Tramadol was injected intraperitoneally, and then, AM251 (1 nmol/0.3 μL), CB1R antagonist and TCS-OX2-29 (1 nmol/0.3 μL), OX2R antagonist, were microinjected individually or concurrently into the CA1. Using in vivo extracellular single-unit recording, the firing of CA1 pyramidal neurons was investigated. Results: Tramadol decreased neuronal activity in CA1 (P < 0.01) but increased it after micro-injection of DMSO. TCS-OX2-29 increased neuronal activity in saline group (P < 0.05) but decreased it in tramadol group. AM251 had no effect on saline group but decreased neuronal activity in tramadol group (P < 0.05). Concurrent micro-injection of TCS-OX2-29 and AM251 had no effect on saline group but decreased neuronal activity in tramadol group (P < 0.05). Conclusions: Our findings suggest that neural activity in CA1 is rapidly affected by acute use of tramadol, and some of these effects may be induced through the endocannabinoid and orexin systems. Thus, the function of endocannabinoid and orexin systems in CA1 may play a role in tramadol addiction.

Background: The present study investigated the plasma level of fibrinogen before and after removing the pump in coronary artery bypass graft (CABG) surgery and its relationship with the need for blood products. Materials and Methods: The present study was performed on 60 patients who were candidates for CABG surgery. The fibrinogen level of these patients was assessed and recorded before surgery and immediately after removing the pump. In addition, their hemoglobin level was recorded before the operation and 2 h after. In addition, the number and type of blood products transfusion were recorded intraoperatively and postoperatively and also at the intensive care unit. Results: Patients' fibrinogen level after removing the pump with the mean of 130.53 ± 122.01 mg/dl decreased significantly compared to before surgery with the mean of mg/dl 224.95 ± 132.88 mg/dl (P < 0.001). In addition, the prognostic value of fibrinogen after removing the pump in determining the postoperative need of blood transfusion showed that the cut-off value of fibrinogen was < 196 mg/dl with a sensitivity of 16.82% and specificity of 80%, but it was not statistically significant (area under the curve [95% confidence interval]: 0.519 [0.350–0.689]; P = 0.825). Conclusion: According to the results of the present study, due to significant changes in fibrinogen levels after removing the pump compared to preoperation, it seems that this factor can play an important role in prognosis of the need to postoperative blood transfusion, although the prognostic value and the critical point mentioned in our study was not significant and it is required to do further studies.

Background: Tramadol is an opioid analgesic with monoamine reuptake inhibitory effects. Although tramadol has been widely used to control pain, there is controversy about the risk of abuse. Therefore, in the present study, the acute effects of tramadol on neuronal activity in the medial prefrontal cortex (mPFC), which is one of the important centers of the reward system, were investigated electrophysiologically. Materials and Methods: Tramadol was injected interperitoneally (12.5 and 25 mk/kg) or subcutaneously (40 mg/kg) and its effect on the firing of mPFC neurons was investigated, using in vivo extracellular single unit recording. Results: Tramadol could not significantly affect neural activity in mPFC, suggesting no acute and rapid effect on mPFC. Conclusions: The present results showed that neural activity in mPFC was not rapidly affected by acute application of tramadol. Since the role of mPFC in tramadol addiction has been elucidated, it can be concluded that these effects may be due to delayed responses or chronic use of tramadol.

Introduction: The aim of this study was to assess the effect of a community-based intervention on social capital, quality of life, self-care, and health literacy among elderly. Materials and Methods: This quasi-experimental trial was conducted at two health-care centers in Isfahan, Iran, which assigned to the intervention and control groups. A total of 86 elderly (60 years or above) enrolled in the study. The intervention program consisted of 12 weekly group sessions with various health topics. Nine sessions held in the health-care center and three local tours in different locations of the neighborhood. The control group received routine care of health centers. Social capital, quality of life, self-care, and health literacy were assessed at baseline and 1 month after the intervention in two groups. Results: Mental component of quality of life (P = 0.026), self-care, and health literacy (P < 0.001) showed a significant increase in the intervention group compared to the control group at 1 month after the intervention. The total score of social capital and the dimensions of local community participation, social agency, feelings of security and trust, interactions with neighbors, and interactions with family and friends improved in the intervention group (P < 0.001). However, there was no significant difference in the dimensions of tolerance of diversity (P = 0.241) and value of life (P = 0.928). Conclusions: This community-based interventions with a variety of diverse and participatory components can be used as a strategy to promote the health of the elderly in primary health care.

Background: Altered heart rate variability (HRV) has been associated with a number of disorders affecting autonomic tone, including recent myocardial infarction, congestive heart failure, and diabetic neuropathy. Furthermore, obstructive sleep apnea (OSA) has been shown to be associated with characteristic disturbances in heart rhythm. In this study, using HRV frequency analysis, an attempt has been made to diagnose or possibly diagnose OSA. Materials and Methods: Using Somnologica version 3.3.1 software (Medcare-Embla), polysomnographic recordings were done. Electrocardiographic signals were digitalized with a sampling rate of 250 Hz. Using the HRV analysis report of this software, low-frequency (LF) and high- frequency (HF) information and LF to HF ratio (LF/HF) were obtained at 5-min intervals, then at cutting points 30, 35, 40, 45, and 50, which indicate the intensity of the apnea and hypopnea index (AHI), were analyzed with mean and standard deviation of HRV frequencies. Results: According to the results reported in this study, comparison of mild, moderate, and severe cases led to no significant differences, while frequency-domain analysis displayed significant LF/HF increase in more severe AHI cases. This can probably be applied in screening high-risk patients, reducing the application of PSG in high probable cases, and providing an estimate of prognosis of potentials patients for the physicians. Conclusions: In the study of frequency-domain analysis, LF/HF increases in more severe AHI cases. These can probably be applied in screening high-risk patients, reducing the application of PSG in high probable cases.

Background: Spatial disease mapping is a widespread tool in ecological analysis to obtain accurate estimates for incidence, relative risks (RRs), prevalence, or mortality rates regarding to increase the incidence of gastrointestinal (GI) cancer in Isfahan in recent years. This study aimed to inspect the RR of GI cancer in Isfahan counties using empirical and full Bayesian model. Materials and Methods: Data of this ecological study were GI cancer cases which registered in health-care system of Isfahan University of Sciences during 2005–2010. We applied shared component model to model the spatial variation incidence rates of the GI cancers. We compared three models such as Gamma–Poisson, lognormal, and Besag, York, and Mollie (BYM) Bayesian. WinBUGS and GIS 10.1 software were used. Results: According to the fitted model, BYM model had best fit to the data. However, in general, ranks of RRs in most counties are identical; counties with higher RR in one map have higher RR in other maps. Geographical maps for three cancers in women were smoother than men. Isfahan has high RR in women, whereas this point is slightly different in men. Daran, FreidoonShahr, and Isfahan are cities which have high RR in esophagus, stomach, and colon cancer, respectively. Conclusions: Lognormal and BYM maps had very similar results. Despite some differences in estimation values, in nearly all maps arias Isfahan had high RR in GI cancer. It is recommended to promote the use of screening programs and increase awareness of people in high RR areas to reduce the incidence of GI cancer.

Background: The present study aims to evaluate the diagnostic exactitude of the intraoperative Chertsey test in tibiofibular syndesmotic injuries in patients with malleolar fractures, in comparison with a computed tomography (CT) scan. Materials and Methods: In this study, patients with malleolar fractures operated between 2018 and 2020 were examined. Thirty-nine patients were enrolled in the study. A three-dimensional preoperative CT scan was obtained. The opposite unfractured ankle was also scanned and considered as the control group. The Chertsey test was performed during the operation to assess the syndesmosis injury. Then, patients were partitioned into two distinct groups, considering the condition of their ankle, namely the Chertsey positive (unstable syndesmosis) group and the Chertsey negative (stable syndesmosis) group. Results: The outcomes of the present survey illustrated that the Chertsey test was positive in 16 patients (41.03%) and negative in 23 patients (59.07%). The median of all CT scan parameters (anterior tibiofibular distances (TFD), middle TFD, posterior TFD, and maximal TFD and volume) before surgery in the group of patients with a positive Chertsey test was significantly higher, measured against the unfractured control group (P < 0.001 for all parameters). Furthermore, a comparison of CT scan parameters and syndesmosis space volume before surgery between the two groups of patients with positive and negative Chertsey test results showed that the measurement of parameters in Chertsey-positive patients was significantly higher than the Chertsey-negative patients (P < 0.001). Conclusion: Chertsey test could be used to diagnose syndesmosis injuries in patients with malleolar fractures due to its high importance in the outcome of patients.

Background: Insulin-like growth factor binding protein-3 receptor (IGFBP-3R) (Transmembrane protein 219 [TMEM219]) binds explicitly to IGFBP-3 and exerts its apoptotic and autophagy signalling pathway. Constructing a Henrietta Lacks (HeLa) h6-TMEM219 cell characterize the therapeutic potent of TMEM219 that could interrupt the IGFBP-3/TMEM219 pathway, in cancer treatment and destructive cell illnesses such as diabetes and Alzheimer's. Materials and Methods: First, to develop stable overexpressed HeLa h6-TMEM219 cells, and Escherichia coli BL21 (DE3) with high IGFBP-3R expression, the purchased pcDNA3.1-h6-TMEM219 plasmid was transformed and integrated using CaCl2 and chemical transfection reagents, respectively. The pcDNA3.1-h6-TMEM219 transfection and protein expression was evaluated by the polymerase chain reaction (PCR), western blotting, and flow cytometry. Following the induction of h6-TMEM219 expression, a protein was purified using Ni-NTA chromatography and evaluated by the sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE). Results: The 606 base pairs sequence in PCR outcomes confirmed successful pcDNA3.1-h6-TMEM219 transformation in E. coli BL21 and integration into the HeLa genome. The analysis of protein samples from induced E. coli BL21 and purified protein demonstrate a band of approximately 22 kDa on SDS-PAGE. Moreover, besides western blot analysis, flow cytometry findings illustrate approximately 84% of transfected HeLa cells (HeLa h6-TMEM219) overexpressed h6-TMEM219 on their surface. Conclusion: We designed a new experiment in the h6-TMEM219 expression procedure in both eukaryotic and prokaryotic hosts. All of our results confirm appropriate transformation and transfection and importantly, approve h6-TMEM 219 membrane expression. Finally, the HeLa h6-TMEM219 cells and the newly purified h6-TMEM219 leverage new studies for molecular diagnostic studies and characterize the therapeutic agents against IGFBP-3/TMEM219 signalling pathway in devastating illnesses in vitro and in vivo.

Background: CA125 is the most used tumor marker for ovarian cancer monitoring and diagnosis. This study aimed to evaluate the capacity to predict malignancy in women with adnexal tumors using CA125 measurement and ultrasound criteria before the pathological examination. Materials and Methods: This observational diagnostic study was conducted on 300 patients with obvious diagnosis of adnexal mass consists of ovarian masses, fallopian tubes, and masses within the broad ligament referring to Alzahra and Beheshti Hospitals from 2018 to 2019. Ultrasound examinations were done before surgery and malignancy risk was investigated by the ADNEX criterion. Sensitivity, specificity, positive and negative likelihood ratio (likelihood ratio [LR]+ and LR−), and area under the curve (AUC) were calculated. Results: From 284 patients, 260 masses were categorized in benign, 18 were in borderline, and 18 masses were malignant. The mean age of patients with malignant tumors was significantly higher than the others (P = 0.01). Differences in the level of CA-125 were not statistically significant (P = 0.78). Furthermore, the proportion of ascites in the malignant group (16.3%) was significantly higher than the others (P = 0.003). The AUC in ADNEX model (cutoff ≥9%) for differentiation of benign and malignant tumors was 0.75 (95% confidence interval [CI]: 0.69–0.80) with a sensitivity of 0.63 (95% CI: 0.41–0.81) and a specificity of 0.80 (95% CI: 0.74–0.84). Receiver operating characteristic analysis for CA-125 revealed that this variable is not capable for discrimination between benign and malignant tumors as the AUCs of the aforementioned variable were 0.60, 0.60, and 0.52 for the whole patients, premenopause, and postmenopause categories. Conclusion: CA-125 marker, along with other ultrasound findings, can be more accurate in identifying the malignancy of the adnexa tumor.

Background: Tenascin-C (TNC) is a large glycoprotein of the extracellular matrix which associated with poor clinical outcomes in several malignancies. TNC over-expression is repeatedly observed in several cancer tissues and promotes several processes in tumor progression. Until quite recently, more needs to be known about the potential mechanisms of TNC as a key player in cancer progression and metastasis. Materials and Methods: In the present study, we performed a bioinformatics analysis of breast and colorectal cancer expression microarray data to survey TNC role and function with holistic view. Gene expression profiles were analyzed to identify differentially expressed genes (DEGs) between normal samples and cancer biopsy samples. The protein-protein interaction (PPI) networks of the DEGs with CluePedia plugin of Cytoscape software were constructed. Furthermore, after PPI network construction, gene-regulatory networks analysis was performed to predict long noncoding RNAs and microRNAs associated with TNC and cluster analysis was performed. Using the Clue gene ontology (GO) plugin of Cytoscape software, the GO and pathway enrichment analysis were performed. Results: PPI and DEGs-miRNA-lncRNA regulatory networks showed TNC is a significant node in a huge network, and one of the main gene with high centrality parameters. Furthermore, from the regulatory level perspective, TNC could be significantly impressed by miR-335-5p. GO analysis results showed that TNC was significantly enriched in cancer-related biological processes. Conclusions: It is important to identify the TNC underlying molecular mechanisms in cancer progression, which may be clinically useful for tumor-targeting strategies. Bioinformatics analysis provides an insight into the significant roles that TNC plays in cancer progression scenarios.

The emerging of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak is associated with high morbidity and mortality rates globally. One of the most prominent characteristics of coronavirus disease-19 (COVID-19) is lymphopenia, which is in contrast to other viral infections. This controversy might be explained by the evaluation of impaired innate and adaptive immune responses, during the SARS-CoV-2 infection. During the innate immune response, poly-ADP-ribose polymerase hyperactivated due to virus entry and extensive DNA damage sequentially, leading to nicotinamide adenine dinucleotide (NAD)+ depletion, adenosine triphosphate depletion, and finally cell death. In contrast to the immune response against viral infections, cytotoxic T lymphocytes decline sharply in SARS-CoV-2 infection which might be due to infiltration and trapping in the lower respiratory tract. In addition, there are more factors proposed to involve in lymphopenia in COVID-19 infection such as the role of CD38, which functions as NADase and intensifies NAD depletion, which in turn affects NAD+–dependent Sirtuin proteins, as the regulators of cell death and viability. Lung tissue sequestration following cytokine storm supposed to be another reason for lymphopenia in COVID-19 patients. Protein 7a, as one of the virus-encoded proteins, induces apoptosis in various organ-derived cell lines. These mechanisms proposed to induce lymphopenia, although there are still more studies needed to clarify the underlying mechanisms for lymphopenia in COVID-19 patients.

Background: Mortality due to acute coronary syndrome (ACS) has dramatically diminished because of performing life-saving interventions. This study aims to assess the metabolic risk factors and heart healthy lifestyle following the first episode of ACS under percutaneous coronary intervention (PCI) treatment after the 6-month follow-up. Materials and Methods: This is a longitudinal study conducted on 40 patients who underwent PCI because of the first episode of ACS. The patients' information including age, weight, abdominal circumference, smoking, functional capacity, patients' metabolic equivalent of task (METS), and laboratory tests including triglycerides (TGs), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), creatinine, fasting blood sugar (FBS), and hemoglobin A1C were recorded before discharge and reassessed after 6-month follow-up. Results: The patients were dominantly male (92.5%) with an average age of 56.8 ± 7.11 years. Physical activity and functional capacity (METS) significantly improved within 6 months (P = 0.019). BMI significantly improved; however, although the abdominal circumference decreased, it was not significant (P = 0.28). The number of smokers (P = 0.12) and the daily number of smoked cigarettes (P = 0.37) nonsignificantly decreased within 6 months. However, HDL-C (P = 0.013) and LDL-C (P = 0.027) changes were not desirable. TG, FBS, and blood pressure did not statistically significant change (P > 0.05). Conclusion: Although BMI, physical activity, and METS remarkably improved, waist circumference decreased nonsignificantly and lipid profile got worse paradoxically. Although this population is limited for generalization, this study shows that we require further schedules to improve ACS secondary prevention practice in our community.

Background: Thyroid hormones are essential to maintain the tissue's metabolism throughout the life. Thyroid hormones exert their effects on physiology and almost all body functions. Carrot is a rich source of iodine and carotenoids that can interfere in the synthesis of thyroid hormones. Materials and Methods: The present study was designed to investigate the effects of carrot consumption on T4 levels and its effect on memory, nerve conduction velocity (NCV), animal weight, and finally, on water and food intake in Wistar rats. In this study, 24 male rats were used and divided into three groups: Control, Ca 200 mg/kg, and Ca 400 mg/kg. Results: The results indicated that carrot consumption at Ca 200 mg/kg treated group increased the level of serum T4 and induced hyperthyroidism. Animal weight in both treated groups did not change compared to the control group (P > 0.05). Water and food consumption, and the level of T4 in Ca 200 mg/kg group increased when compared to the control group (P < 0.05). NCV in both treated groups was not significantly different in comparison with the control group (P > 0.05). Spatial memory and passive avoidance memory in both treated groups significantly decreased compared to the control group (P < 0.05). Conclusion: Carrot consumption, via increases the synthesis of thyroid hormones, creates hyperthyroidism, but due to induced moderate hyperthyroidism did not impact on weight. Moderate hyperthyroidism induced appetite and memory impairment. Then increased food intake or effect of hyperthyroidism on metabolism increased water intake.

Background: Sacroiliac pain is one of the causes of low back pain, representing with discomfort and tenderness in the sacroiliac joint. Interventional procedures might be beneficial in cases unresponsive to medical treatments. Here, we aimed to investigate the effects of intra-articular corticosteroid injections in patients with sacroiliac pain. Materials and Methods: This is a clinical trial performed in 2017–2018 in Kashani Hospital, Isfahan, on patients with low back pain and formerly diagnosed with sacroiliac pain. Patients were recruited based on inclusion and exclusion criteria. Corticosteroid injections were performed for patients. Patients were visited within 2 weeks, 4 weeks, and 6 months after interventions, and pain and disabilities of patients were assessed using the numerical rating scale (NRS) and Oswestry Disability Questionnaire. Results: A total number of 27 patients entered our clinical trial. We showed that the mean NRS score among patients before interventions was 8.01 ± 0.96. Assessments of disability score also indicated that the mean disability scores was 41.48 ± 7.48. Our data also indicated that there was a significant reducing trend in both NRS and disability score after interventions (P < 0.001 for both items). Conclusion: Intra-articular steroid injection is associated with significantly reduced pain and disability in patients with sacroiliac pain. Previous studies evaluated variable methods and reported that this method has high values and significant advantages compared with other techniques which were in line with our results.

Background: The aim of this study was determination of the effect of the transversus abdominis plane block (TAP block) with ropivacaine 0.5% in relieving postoperative pain after laparoscopic gynecologic surgery. Materials and Methods: The population of the double-blinded clinical trial study included 200 women candidates for elective laparoscopic gynecologic surgery who referred to Al-Zahra and Beheshti hospitals in Isfahan during 2016–2018. In the TAP block group in addition to standard general anesthesia, an anesthetic drug Ropivacaine (Naropin, 0.5%) was injected at a dose of 0.5 mg/kg between transverse abdominal muscle and internal oblique muscle facia. And in control group just received standard general anesthesia. Hence, the severity of pain and nausea and vomiting is recorded at the time of recovery, at 30 min, 2, 4, 6, 12, and 48 h after the surgery. Results: The results of this study showed that in all periods of time (30 min, 2, 4, 6, 12, 24, 36, and 48 h after the surgery), mean pain score in TAP block group was lower than control group (P < 0.001). Hence that, in the 48 h after the surgery, the pain score in the TAP block group with a mean of 0.46 ± 0.50 was significantly lower than the control group with a mean of 1.06 ± 0.68 (P < 0.001). Nausea and vomiting between the two groups were no significant differences. There was no decrease in narcotic use or length of stay among those who received the TAP block. Conclusions: TAP block with ropivacaine 0.5% had a significant role in reducing postoperative pain of laparoscopic surgery.

Background: This study aimed to compare the efficacies of four anesthetic induction drugs (thiopental, propofol, midazolam-thiopental, and etomidate-propofol) on cardiovascular response during laryngeal mask airway (LMA) placement in eye surgery. Materials and Methods: The present clinical trial study included 128 patients who were candidates for ophthalmic surgery in four groups. Patients in the first group were given a combination of midazolam (0.04 mg/kg) with thiopental (2.5 mg/kg) (Group T + M). We administered propofol alone (2.5 mg/kg) to patients in the second group (Group P). The third group received a combination of etomidate (0.1 mg/kg) with propofol (1 mg/kg) (ET + P group) and patients in the fourth group received thiopental drug (5 mg/kg) alone (Group T). Then, the stability of patients' hemodynamic parameters before anesthesia was evaluated and compared immediately after anesthesia, 1, 3, and 5 min after LMA placement. Results: There was no significant difference between the four groups in changes in oxygen saturation level (P > 0.05). Furthermore, the difference between decreased systolic blood pressure and diastolic blood pressure over time was not significant in 5 min in both Groups T + M and T (P > 0.05). In addition, the stability of these two groups was higher than the other two groups (P < 0.05) and the most unstable group was Group P. The changes pulse rate in the P group were significant (P < 0.05). Conclusion: According to the results of the current study, thiopental and Midazolam can be used as an effective induction compound to facilitate LMA insertion with higher hemodynamic stability compared to propofol alone, propofol and etomidate, and thiopental alone.

Background: This research intended to investigate the characteristics of COVID-19, accurately evaluate radiological findings, and compare it with laboratory evidence of coronavirus. Materials and Methods: A retrospective study of 120 consecutive cases with a mean age of 55.9 ± 15.82 years and laboratory-confirmed COVID-19 pneumonia was performed. On admission, C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) levels were tested. Computed tomography (CT) findings and scored pulmonary involvement were evaluated. Results: An elevated level of CRP and mildly raised ESR was seen in all patients. ESR showed a meaningful difference between both genders (P < 0.05). Ninety-four (78.3%) patients showed peripheral pulmonary lesions and 119 patients had ground-glass opacity (99.2%), 110 (92.4%) had consolidation, and 9 patients (7.5%) had linear opacities. Of 120 cases, 25 (20%) had bronchial changes, 25 (20%) had air bronchogram, 11 (9.2%) had bronchial distortion, and 2 had mediastinal lymphadenopathy. The CT scores in males and females were 17.41 ± 4.86 and 14.65 ± 4.96, respectively with a significant difference between both genders (P = 0.001). CT score difference was significant between both genders (P = 0.01). The largest lung lesion diameter in both sexes (male: 46.0725.75 and female: 57.9131.14) showed a meaningful difference. CRP (r = 0.10; P < 0.05) and ESR (r = 0.15; P < 0.05) were correlated with the CT scores. Conclusion: the results indicated that the infection involved lung parenchyma and interstitium. CRP and ESR levels were correlated with lung lesions and showed positive performance in predicting severity and disease monitoring.

Diagnosing breast cancer (BC) in early stages increases the chances of treating this cancer in men. However, because BC is very rare in men, especially inflammatory BC (IBC), it is unlikely that screening men for BC by mammography or other tests would yield promising outcomes. The aim of this study was to report IBC in a 53-year-old man. The case was a 53-year-old man with a history of mass in the left breast and trauma to the same side as well as swelling and severe redness of the breast skin. The patient underwent neoadjuvant chemotherapy and relative responded to medical treatment. He then underwent modified mastectomy surgery and initial chest wall repair followed by radiotherapy. IBC in men is challenging due to its rarity, unknown biological behaviors, and difficulty in early diagnosis. This tumor is usually detected in advanced stages in the elderly and has a poor prognosis.

Background: In the present study, the effects of intra-basolateral amygdala (BLA) blockade of dopamine D1 receptor on morphine-induced conditioned place preference (CPP) were investigated in male Wistar rats. Materials and Methods: A 5-day CPP paradigm was used. Morphine was injected subsequently at effective (5 mg/kg) and ineffective (0.5 mg/kg) doses. SCH 23390 (0.5– μg/rat), as a selective D1 receptor antagonist, was microinjected bilaterally into the BLA. Results: Effective dose of morphine induced a significant CPP, and increased the locomotor activity during the testing phase. The results showed that morphine-induced CPP was significantly suppressed by D1 receptors antagonist in BLA in the acquisition phase and caused an aversion even at high doses. The antagonist also significantly prevented CPP expression. Morphine increased the motor activity, but the D1 receptors blockade, significantly reduced it. Conclusions: The findings of this study suggest a possible role for BLA dopamine D1 receptors in reward responses in morphine dependency.

Parsonage-Turner syndrome (PTS) is a rare syndrome of unknown etiology; however, it is believed that an abnormality of immune response after a previous infection may be the cause of the disease. We report neuralgic amyotrophy in a patient with a history of kidney transplantation with severe acute respiratory distress syndrome coronavirus 2 infection. This literature is reviewed regarding clinical presentation, etiology, treatment, and prognosis of PTS after COVID-19 infection. We should consider PTS as another complication of COVID-19 infection.

Background: One of the most common problems in the intensive care units (ICUs) is pressure ulcers (PUs). The present study aimed to evaluate the effectiveness of aloe vera gel, olive oil, and compound aloe vera gel-olive oil in the prevention of PUs. Materials and Methods: This randomized clinical trial was conducted on 240 patients. They were randomly divided into four groups, aloe vera gel (n = 60), olive oil (n = 60), aloe vera gel-olive oil combination (n = 60), and control (n = 60). Braden scale and National Pressure Ulcer Advisory Panel scale were used to collect data. The intervention was performed for 30 days. In the intervention and control groups, the patient received routine care. In each intervention group, 10–15 ml of olive oil or aloe vera gel or a combination of olive oil and aloe vera was rubbed into body areas under pressure. Results: There were no PUs detected in all groups before the intervention; after the intervention, 12 patients in the olive group, 20 patients in the aloe vera group, 10 patients in the aloe vera-olive combination group, and 22 patients in the control group developed PUs. The results reported 40% of the patients with stage 1 PU and 10% of them with stage 2. Conclusion: Due to the effectiveness of olive oil and aloe vera-olive oil combination in preventing PU, it is recommended to use these herbal compounds in preventing PU on ICU patients.

Schwannoma is a rare tumor in the colon which originates from the peripheral nerve plexus. Most of the cases have been asymptomatic but occasionally present as an obstructive mass. Abdominal investigations are effective in some cases, but usually, they are not informative. A significant number of cases have been detected after their operation by histopathology examination. Immune and histochemical staining shows the spindle cells that have been positive for S-100 and vimentin, but negative for CD34 and smooth muscle actin. If the diagnosis of Schowannoma is confirmed preoperatively, segmental resection is recommended. In this case report, we presented a 58-year-old woman with pelvic mass and normal colonoscopy that mimic extramural large uterine myoma with extraluminal pressure effect on the rectosigmoid.

Background: Helicobacter pylori (H. pylori), a spiral-shaped bacterium colonizing the human stomach, is generally acquired in childhood. This pathogen is highly diverse and can be used as genetic markers for predict the history of human migrations. This study aimed to determine the genetic diversity of H. pylori isolates from patients with dyspepsia by the multi-locus sequence typing (MLST) and update data on the prevalence of H. pylori among Iranian dyspeptic patients. Materials and Methods: In this descriptive cross-sectional study, 165 gastric biopsy specimens were obtained from patients with dyspepsia referred to Dr. Shariati Hospital of Isfahan, Iran, from April to July 2018. The status of H. pylori infection was determined by FISH in paraffin-embedded biopsy specimens. MLST of seven housekeeping genes was performed for 20 H. pylori isolates. The phylogenetic tree was plotted using CLC v8 and iTol software. Results: The overall prevalence of H. pylori infection was 53.3%. In the results of the analysis of MLST, a total of 14 new STs were recorded. The results of the global analysis showed that all the isolates, with a wide diversity, have a genetic affinity with members of the European population, such as Italy and Russia, and are in the hpEurope haplotype. Conclusion: Given the high prevalence of H. pylori infection in this region, early and accurate identification of patients seems necessary. Sequence analysis and determination of the origin of the phylogeny of strains can be effective in clinical management and monitoring of risk factors for chronic and recurrence of infection.

Introduction: We aimed to evaluate the effect of shock wave therapy on the improvement of symptoms and function of patients with Dupuytren's contracture. Materials and Methods: This research is a pre-post intervention study, conducted among patients referred to the physical medicine clinics of Isfahan during 2019–2020. In this study, subjects experienced shock wave therapy for 6 sessions, each in a week, and improvement of symptoms and function were assessed and compared after the period of study and follow-up (before treatment, 6 weeks after treatment, and 14 weeks after treatment). The pain visual analog scale and disabilities of the arm shoulder and hand questionnaire were completed for all patients at the mentioned time, and the finger contraction angle was also measured by a goniometer over these intervals. Results: Twenty patients, 11 (55%) men and 9 (45%) women participated in the study. The mean and standard deviation of their age was 66.6 ± 7.11 years. The trend of pain severity of patients was continuously and significantly decreasing up to 14 weeks, which implies the effectiveness of the intervention (P < 0.05). Moreover, the patients' functional status improved due to the continuation of the intervention, and its trend was decreasing up to 14 weeks (P < 0.05). As for the contraction angle, there was a continuous and significant decreasing trend until week 14, and the intervention was also effective on the contraction angle (P < 0.05). Conclusion: It can be concluded that shock wave therapy can be effective in improving the symptoms and function of patients with Dupuytren's Contracture.

Background: COVID-19 pandemic placed immense pressure on health systems. The current study aimed to evaluate the symptoms of COVID-19 in Isfahan province and their association with disease outcome. Materials and Methods: In this cross-sectional study, which was conducted on patients with a definite diagnosis of COVID-19, as a part of the investigations performed by the Deputy for Public Health of the Isfahan University of Medical Sciences, the frequency of underlying diseases, and general, respiratory, gastrointestinal, neurological, renal, cardiac, dermal, hearing symptoms are assessed using a checklist. The participants were followed up 1 month after definitive diagnosis, and the outcome of the disease (recovery or death) was recorded. Results: Of 300 patients, 143 (47.4%) were male and 157 (52.6%) were female. The mean age of patients was 43 ± 17.84 years. Muscle pain and fatigue were the most common early symptoms (63% and 60.3%, respectively). Age, sex, level of education, and occupation of patients and general, respiratory, and gastrointestinal symptoms and underlying diseases of respiratory disease showed a statistically significant association with the disease outcome (P < 0.05). Conclusion: General, respiratory, and gastrointestinal symptoms were associated with an increased risk of death due to COVID-19. General, visual, and hearing symptoms, and diabetes, cardiovascular diseases, and respiratory disease had a statistically significant association with the hospitalization of patients.

Background: The aim of this study was to evaluate ultra-widefield (UWF) fundus fluorescein angiography (FFA) findings in patients with Fuchs' uveitis syndrome (FUS). Materials and Methods: This cross-sectional study was conducted in patients with FUS. All the patients underwent a complete ophthalmologic examination, and FFA was carried out with Optos UWF retinal imaging. Standard FFA and image acquisition consisted of early phase (15–45 s) images, and late-phase (5–10 min) images were also obtained for both eyes. Results: Forty eyes from twenty unilateral FUS patients, including 11 females (55%), who had a mean age of 38.50 ± 6.97 years, were enrolled. Eighty-five percent of the FUS eyes had optic disc hyperfluorescence (ODH) in the FFA. A significant relationship was observed between ODH and iris heterochromia (P = 0.004). ODH was seen in all the patients with iris heterochromia (n = 16). Peripheral vascular leakage (PVL), capillary nonperfusion, chorioretinal scar, and vascular sheathing were observed in 3, 3, 2, and 8 of the patients' eyes, respectively. Conclusion: UWF FFA imaging seemed to be mandatory for evaluating the prognosis of the FUS patients, and another investigation may require to be conducted to evaluate the effect of antivascular endothelial growth factor agents for the management of PVL in these patients.

Background: Parkinson's disease (PD) is a neurological disorder caused by decreasing dopamine in the brain. Speech is one of the first functions that are disrupted. Accordingly, speech features are a promising indicator in PD diagnosis for telemedicine applications. The purpose of this study is to investigate the impact of Parkinson's disease on a minimal set of Jitter and Shimmer voice indicators and studying the difference between male and female speech features in noisy/noiseless environments. Materials and Methods: Our data includes 47 samples from nursing homes and neurology clinics, with 23 patients and 24 healthy individuals. The optimal feature for each category is studied separately for the men's and women's samples. The focus here is on the phonation in which the vowel/a/is expressed by the participants. The main features, including Jitter and Shimmer perturbations, are extracted. To find an optimal pair under both noisy and noiseless circumstance, we use the Relief feature selection strategy. Results: This research shows that the Jitter feature for men and women with Parkinson's is 21 and 33.4, respectively. While the Shimmer feature is 0.1 and 0.06. In addition, by using these two features alone, we reach a correct diagnosis rate of 79% and 81% for noisy and noiseless states, respectively. Conclusion: The PD effects on the speech features can be accurately identified. Evaluating the extracted features suggests that the absolute value of the selected feature in men with PD is higher than for healthy ones. Whereas, in the case of women, this is the opposite.

Background: Posterior reversible encephalopathy syndrome (PRES) is a rare clinical-radiological syndrome characterized by such symptoms as headaches, altered consciousness, blurred vision, seizure, and focal neurological deficits. We herein present well-documented PRES cases and discuss the risk factors and characteristic imaging patterns of this syndrome. Materials and Methods: We prospectively examined 31 patients with PRES in Alzahra Hospital, Isfahan, Iran, and compared the underlying diseases of PRES in terms of their clinical features and cranial magnetic resonance imaging (MRI) findings. Results: The most common underlying disease was hypertension (90.3%), followed by systemic lupus erythematosus (32.3%), preeclampsia (25.8%), chronic renal failure (22.6%), and rheumatoid arthritis (22.6%). Interestingly, we also reported heroin abuse as a possible risk factor for PRES (9.7%). The most frequent clinical signs were headaches (54.8%), seizure (54.8%), and blurred vision (35.5%). The most frequent lesions on cranial MRI were in the parieto-occipital area (87.1%), followed by the cerebellum (19.4%) and the frontal lobe (12.9%). Other abnormalities on MRI were less common. In addition, 16.1% of the study population had vasospasm on magnetic resonance arteriography (MRA). Clinical recovery was followed by radiological resolution in all the patients. Conclusions: The clinical presentation is nonspecific, most patients present with a combination of symptoms, particularly headaches and seizure. MRI is crucial for the diagnosis of PRES, and MRA is useful in that it can identify associated vasospasm. Timely diagnosis and treatment are required to avoid a devastating outcome.

Background: The aim of the study is to define the prevalence and antimicrobial susceptibility pattern of bacteria from cases of urinary tract infections (UTIs). Materials and Methods: A retrospective analysis of urinary pathogens and their antimicrobial susceptibility was done on urine cultures at Shiraz University Laboratory from 2015 to 2017. Antimicrobial susceptibility tests have done using the disk-diffusion technique as per the standard of CSLI. Results: During 2 years of study, 3489 samples were culture positive. Escherichia coli was the dominant isolate (84%), followed by Klebsiella spp. (10.7%) and Enterococci spp. (2,2%). The overall resistance rates to trimethoprim-sulfamethoxazole, ceftriaxone, and ciprofloxacin were 56.1%, 47.2%, and 37%, respectively. The most frequently isolated bacteria were E. coli, which had resistance rates of 58.6%, 49.1% to TMP-STX, and cefixime, also sensitivity rates of 95.1% to nitrofurantoin (FM). Conclusions: In the study area, resistance rates to fluoroquinolones and cephalosporins were high. Because most isolates were sensitive to FM and aminoglycoside, they are suggested as appropriate antimicrobials for empirical treatment of UTIs before available urine culture results.

Background: Considering the effect of beclomethasone on allergic rhinitis or nasal polyps, it has been attempted to find the best method of using this drug to have the maximum effect and increase the patients' satisfaction. Therefore, the aim of this study was to compare the efficacy of beclomethasone aerosol and aqueous nasal sprays in the patients with nasal polyps. Materials and Methods: This double-blind randomized clinical trial was conducted on 60 patients with nasal polyps. The patients were divided into two groups. The first group (beclomethasone dipropionate aqueous [BD-AQ] group) was treated with daily two puffs of beclomethasone aqueous nasal spray 50 μg in each nostril, and the second group (beclomethasone dipropionate aerosol [BD-A] group) was treated with two puffs of aerosol beclomethasone 50 μg in each nostril daily for 6 months. At the beginning of the study, the sino-nasal outcome test-22 (SNOT-22) and Lund-Mackay scores were recorded after the evaluation of disease status and the severity of symptoms. Results: The results of this study demonstrated that the mean changes in Lund-Mackay and SNOT-22 scores (83 ± 6.30 and 4.25 ± 31.60, respectively) in the BD-A group were significantly higher than the BD-AQ group (2.01 ± 3.87and 9.83 ± 24.13, respectively) (P < 0.05), but there was no significant difference in the patients' satisfaction between the two groups (P > 0.05). Conclusion: According to the results of this study, patients with nasal polyps showed a significant improvement following both the interventions, but the disease severity in the BD-A group was significantly higher than the BD-AQ group based on the mean values of Lund-Mackay score.

Usher syndrome is a heterogeneous genetic disease that is the most common cause of hereditary blindness–deafness. This syndrome is the most prevalent syndrome associated with retinitis pigmentosa. A 25-year-old man referred to us with hearing loss and vision diminution since childhood which has gradually worsened. Visual acuity of both eyes was 20/100. Slit lamp examination of the left eye revealed endothelial stellate keratic precipitates, mild anterior chamber reaction, iris heterochromia, ectropion of uvea, and mild posterior subcapsular cataract. There were also no crypts and abnormal vessels in the left eye iris. His intraocular pressure was 14 mmHg in the right eye and 18 mmHg in the left one. Funduscopy demonstrated waxy pallor optic nerve, marked arterial narrowing, and retinal bone spicule pigment formation in both eyes. We report for the first time a very rare association between Usher syndrome, Fuchs heterochromic uveitis (FHU), and ectropion uvea. To our knowledge, no association has been reported between ectropion uvea, FHU, and Usher syndrome.

Background: Growth factors and chemical stimulants have key role in cartilage tissue engineering, but these agents have unfavorable effects on cells. Avocado soybean unsaponifiables (ASU) has chondroprotective and anti-inflammatory effects. In this study, fibrin2nanoparticles (FNP)/ASU, as a new delivery system, with stem cells applied for cartilage tissue engineering in poly (lactic-co-glycolic) acid (PLGA) scaffold. Materials and Methods: FNP/ASU prepared by freeze milling and freeze drying. NFP/ASU was characterized by dynamic light scattering (DLS). PLGA-NFP/ASU scaffold was fabricated and assessed by scanning electron microscope (SEM). Human adipose-derived stem cells (hADSCs) were seeded on scaffold and induced for chondrogenesis. After 14 days, cell viability and gene/protein expression evaluated. Results: The results of DLS and SEM indicated that nanoparticles had high quality. The expression of type II collagen and SOX9 and aggrecan (ACAN) genes in differentiated cells in the presence of ASU was significantly increased compared with the control group (P and lt; 0.01), on the other hand, type I collagen expression was significantly decreased and western blot confirmed it. Conclusions: This study indicated FNP/ASU loaded in PLGA scaffold has excellent effect on chondrogenic differentiation of hADSCs and tissue engineering.

Background: The expression of microRNAs (miRNAs) as circulating biomarkers has been underlined in multiple sclerosis (MS) in the last decade. Due to the presence of a possible relationship between expressed miRNAs and heterogeneous appearances of the pathological processes in MS, the present study attempts to evaluate the expression of miR-129 and miR-549a in patients with MS in comparison with healthy control (HC) group. Materials and Methods: Peripheral blood mononuclear cells were separated from fifty patients with MS (subtypes including relapsing–remitting MS and secondary progressive MS) in the Kashani Hospital, Isfahan, Iran, and fifty people as HC group. After RNA extraction and complementary DNA synthesis, the expression of miR-129 and miR-549a was evaluated in patients with MS in comparison with the HC group using a quantitative real-time polymerase chain reaction assay. The data were analyzed using the Kolmogorov–Smirnov and Mann–Whitney tests. Spearman's correlation coefficient was used to examine the relationship between miR-129 and miR-549a with age. Results: The results showed that the expression of miR-129 and miR-549a was not significant in patients with MS in comparison with the HC group. Furthermore, the relationship between such miRNAs and age and gender was not significant. Conclusion: We suggest the expression of miR-129 and miR-549a as circulating miRNAs in peripheral blood mononuclear cells could not be considered a biomarker for diagnosis and Para clinical.

Background: We aimed to compare the effectiveness of Levetiracetam and Piracetam on the severity and frequency of spells in children with severe breath-holding spells (BHS), i.e. bening, paroxysmal, and nonepileptic events that are common in early childhood. Materials and Methods: This study is a randomized controlled clinical trial in 71 children from 6 months to 6 years of age with BHS. They were randomly assigned to the two study groups (Levetiracetam and Piracetam group). The frequency and severity of BHS and the response to treatment were recorded on monthly visits during our 3 months follow-up. Results: There was a significant decline in the average number of frequency of spells before and after 3 months of treatment in each group in this study. Levetiracetam had significant effects on the average incidence of the loss of consciousness and seizure-like movements in our study, while Piracetam had no significant effect on the loss of consciousness. Our result showed better response in the Levetiracetam group (88.9% partial or complete response after treatment) compared with the Piracetam group (77.1% partial or complete response after treatment); however, it was not significant. It seems that Levetiracetam had better effect than Piracetam in some aspects in the treatment of BHS. Conclusions: Both Piracetam and Levetiracetam are safe and had significant effects on the frequency of BHS in our study, however, levetiracetam showed superior effects on the severity of BHS.

Background: Trinucleotide repeat (TNR) expansion is a kind of mutation with instability in the number of microsatellite repeats. This nature of mutation leads to the different kinds of neurological and neuromuscular disorders; among them, fragile-X syndrome is the main cause of intellectual disability in which the increasing number of CGG TNR in 5' untranslated region is the main reason for epigenetic silencing of Fragile X mental retardation 1 gene. The aim of this study is to decrease the CG content of the candidate region to facilitate amplification by conventional polymerase chain reaction (PCR). Bisulfite treatment of the genomic DNA results in conversion of unmethylated cytosine to uridine and may overcome the diagnostic pitfalls. Materials and Methods: The whole blood DNA was extracted and bisulfite treated. Then any simplification in PCR process of desire sequence were assayed through following conventional PCR using specifically designed primers for converted sequence. Bisulfite-treated PCR product of a nearby sequence confirmed our results as a conversion control. Results: Both the control and the candidate sequences undergoing bisulfite treatment were successfully amplified by PCR. Conclusions: Decreasing the GC content of the sequence by bisulfite treating could be a new approach to overcome difficulties in amplifying GC-rich sequences.

Background: postoperative shivering is a common complication of various surgical, so far no acceptable theory has been presented on the prevention of it. The aim of this study was to compare the effect of intravenous injection of dexmedetomidine, ondansetron, and pethidine on postoperative shivering among patients under abdominal surgery. Materials and Methods: In a double-blind clinical trial study, 128 patients undergoing abdominal surgery were selected and randomly divided into four groups of 32. In the 4 groups, 0.5 μg/kg dexmedetomidine, 0.5 mg/kg pethidine, 0.1 mg/kg ondansetron, and the same volume of normal saline were injected intravenously when anesthetics were discontinued and the incidence and severity of postoperative shivering were determined and compared in four groups. Results: The incidence of postoperative shivering was 12.5% in the dexmedetomidine group, 31.3% in the ondansetron group, 31.3% in the pethidine group, and 50% in the control group (P = 0.015). The mean of shivering severity in the four groups was 1.33 ± 0.5, 0.17 ± 0.8, 1.09 ± 0.4, and 1.13 ± 0.39, and the difference between the four groups was significant (P = 0.005). Conclusion: The use of all three drugs of dexmedetomidine, ondansetron, and pethidine is effective in decreasing the incidence of postoperative shivering, but the use of dexmedetomidine is associated with less postoperative shivering, better hemodynamic stability, and fewer other postoperative complications.

Background: Cognitive impairment is an unpleasant and progressive mental disorder characterized by learning and memory disabilities. Stress and alcohol are two known environmental factors that increase cognitive impairment. This study was designed to evaluate the relative role of cyclooxygenase 2 in alcohol or stress-induced cognitive impairment. Materials and Methods: Male Wistar rats were randomly divided into groups with six rats in each. The groups included sham, control, alcohol (15% ethanol in drinking water), and restraint stress (restraint 6 h per day). Three separated groups received celecoxib at a dose of 20 mg/kg in addition to those listed above. The treatments continued daily for 28 days. The object recognition task (ORT) and Morris water maze (MWM) are used to evaluate the learning and memory. Results: Alcohol or restrain stress significantly increased the time and distance needed to find the hidden platform in MWM. Furthermore, they decreased the recognition index in ORT compared to the control group. Administration of celecoxib significantly decreased the required time and traveled distance to reach the platform in alcohol-treated animals but not in the stress-exposed rats. Celecoxib also significantly increased the recognition index both in alcohol- or restraint stress-exposed animals. Conclusion: We found that either alcohol or restraint stress impairs memory in rats. In MWM, celecoxib improved the alcohol-induced memory impairment but could not show a reduction in memory deterioration due to restraint stress. In ORT, celecoxib reversed memory impairment due to both alcohol and restraint stress.

Background: Peripheral neurotoxicity is a common side effect of many anticancer chemotherapy drugs, including paclitaxel. Peripheral neurotoxicity may present as changes in sensory function and mild paresthesia that, in turn, can lead to alleviation of the prescribed dose of the medication. The aim of this study was to evaluate the effectiveness of acute and chronic doxepin administration on development and expression of neuropathic pain during the treatment of cancer with paclitaxel. Materials and Methods: Neuropathic pain was induced in mice by paclitaxel (2 mg/kg, intraperitoneally [i.p.,] once daily from day 1 to day 5) that caused mechanical and cold allodynia. Doxepin was administrated every day from day 6 to 10 (10 and 15 mg/kg i.p.). Mechanical and cold allodynia was evaluated on day 11 of the experiment in both the test and the control group. Results: Daily administration of doxepin (2.5, 5, and 10 mg/kg i.p.) from day 1 to 5 significantly inhibited the development of cold and mechanical allodynia. As well doxepin administration (5 and 10 mg/kg i.p.) from the 6^th day, to 10^th day significantly inhibited cold and mechanical allodynia expression. To address the concerns associated with the effectiveness of chemotherapy agents on the tumor, we evaluated paclitaxel cytotoxicity effect in combination with doxepin. Our observations indicate that doxepin even at high concentrations (1 and 10 μg/ml) does not interfere with the cytotoxic effect of paclitaxel (0.05 μg/ml). Conclusions: These results indicate that doxepin, when administered during chemotherapy, can prevent the development and expression of paclitaxel-induced neuropathic pain.

Backgrounds: The prevalence of metabolic syndrome (MetS) is increasing in developing countries that affects the liver in a variety of ways. This study was designed to investigate the protective role of eugenol on liver damage caused by fructose-induced MetS. Materials and Methods: Thirty male Wistar rats were randomly divided into five groups: 1: tap water (control), 2: fructose, 3: fructose + eugenol solvent, 4: fructose + eugenol 50 mg/kg, and 5: fructose + eugenol 100 mg/kg. At the end of the experiment, blood samples were taken for measurement fast blood glucose (FBG), serum glutamic-oxaloacetic transaminase (SGOT), serum glutamic pyruvate transaminase (SGPT), low-density lipoprotein, high-density lipoprotein, cholesterol, and triglyceride. Results: FBG significantly increased in Group 2 compared to Group 1 (P < 0.001); however, it significantly decreased in Groups 4 and 5 compared to Group 2 (P < 0.05). SGOT and SGPT levels significantly increased in Group 2 compared to the control group (P < 0.001). However, SGOT and SGPT levels significantly decreased in Groups 4 and 5. Malondialdehyde (MDA) and liver tissue damage score (LTDS) significantly increased in Group 2 compared with the control group (P < 0.01), whereas MDA and LTDS decreased in Groups 4 and 5 compared to Group 2 (P < 0.05). Conclusion: Eugenol may ameliorate liver damage in a rat model of fructose-induced MetS, and these protective effects may in part be mediated by improving antioxidant status and reducing oxidative stress and lipid peroxidation. It may also reduce hepatic inflammation and fat accumulation as well as fibrosis of liver cells.

Background: Surgery is one of the treatments commonly used to treat liver hydatid cyst. Remaining of the residual cavity after conservative surgery may lead to some harmful complications. In this study, we evaluated the role of different factors affecting the disappearance of the residual cyst. Materials and Methods: Seventy-five patients were evaluated in 2.5 years. Patients were divided into two groups based on the remaining or disappearance of the residual cavity in follow-up visits. The baseline demographic features, preoperative cysts' size, type of technique used to eliminate the residual cavity, and cavity wall characteristics were compared in the two groups. Results: Residual cavity was disappeared in 46 (61%) patients after 2 years. Calcification of the wall and wall stiffness were more common in patients with the remained residual cavity (89.6% vs. 8.7% [P < 0.001] and 58.6% vs. 30.4% [P < 0.01], respectively). Demographic features, preoperative cysts' characteristics, and the procedure used during surgery were not statistically different between groups. Conclusions: Cyst wall calcification and wall stiffness had a role in predicting residual cavity disappearance. These factors can help surgeons to predict patients at higher risk of posthydatid cyst resection residual cavity.

Background: Osteoporosis is a prevalent elderly complication that is characterized by decreased bone mineral density and increased fracture risk because of dysregulation in bone mineralization and resorption. Physical activity can enhance bone strength by exerting mechanical forces and myokines. Irisin is a myokine that is increased following physical exercise and can affect bones. In this study, 8 weeks of resistance and endurance exercises are applied in mice compared to irisin injection to assess the contribution of the protocols and this myokine to bone strength. Materials and Methods: Thirty-five male NMRI mice were separated into five groups; control, placebo, irisin injection, resistance exercise, and endurance exercise. 8-week of exercise protocols and irisin injection protocol (100 μg/kg/week) was applied. Plasma irisin concentration and bone strength were measured using enzyme-linked immunoassay and 3-point bending assay, respectively. Statistical analyses were done through one-way ANOVA and Tukey test, and P < 0.05 was considered the significant difference. Results: Serum irisin concentration and bone strength in resistance exercise and irisin-injected groups were significantly higher than control and placebo groups (P < 0.0001). Serum irisin concentration, but not bone strength, of the endurance exercise group was also significantly higher than control and placebo groups (P < 0.0001) but lower than resistance and irisin-injected groups. Conclusion: Resistance exercise and irisin injection, but not endurance exercise, are likely to be effective in increasing bone strength. There may be a threshold for plasma irisin level to affect bones which the applied protocols of irisin injection and resistance exercise but not endurance exercise can reach.

Extraintestinal manifestations (EIMs) are common in patients with Crohn's disease (CD). Various reactive cutaneous conditions, including erythema nodosum and pyoderma gangrenosum frequently occur as a part of EIMs. However, cutaneous metastasis of CD is rarely encountered in CD patients. Here, we report a 28-year-old female patient presenting with discharging deep fissures on genital and intergluteal regions. The result of a skin biopsy showed noncaseating granulomas. After rule out all the other differential diagnoses for granulomatous skin lesions, we believe this patient may be a case of CD, presenting with skin metastasis and GI tract involvement has not been occurred during 1-year follow-up. We suggest including cutaneous (metastatic) CD in the list of dermatologic differential diagnoses for cutaneous lesions of these sites. These lesions can occasionally precede gastrointestinal (GI) involvement by months and years, therefore, an appropriate follow-up needs to be done to detect GI lesions as soon as they appear.

Background: Magnetic resonance cholangiopancreatography (MRCP) is a noninvasive method to detect pancreaticobiliary strictures. In this study, we aimed to evaluate the diagnostic performance of MRCP and detect sensitive and specific radiologic features in distinguishing malignant and benign pathologies. Materials and Methods: In this study, 50 patients with biliary obstruction and a confirmed diagnosis using histopathology were included. The pathologies were evaluated using MRCP which were categorized into malignant and benign strictures. The etiology of strictures was detected using histopathology and endoscopic retrograde cholangiopancreatography. The diagnostic performance of MRCP was calculated using SPSS software. P < 0.05 was considered statistically significant. Results: Of 50 patients, 23 patients (46%) had malignant strictures based on MRCP and histopathology. The sensitivity and specificity of MRCP to detect malignancy were 95.7% and 96.3%, respectively. The most sensitive MRCP features to detect malignancy were upstream biliary duct dilation, abrupt tapering, and the presence of a solid mass with sensitivity 100%, 95.7%, and 78.2%, respectively. The malignancy rate was significantly higher in the strictures with length >11.5 mm or wall thickness >2.75 mm (P < 0.05). Conclusion: MRCP is a sensitive method to differentiate malignant lesions from benign pathologies. A long and thick stricture with the presence of a solid mass, upstream biliary duct dilation, and abrupt tapering is highly suggestive of malignancy.

Background: The diagnosis of pulmonary embolism (PE) because of nonspecific clinical presentation remains as a challenge for emergency physicians. Arterial to end-tidal partial pressure of carbon dioxide (P(a-Et)CO₂) gradient may be useful in the evaluation of PE. This aimed to define the diagnostic role of P(a-Et)CO₂ gradient by sidestream capnography, as a noninvasive method, and D-dimer in patients with PE. Materials and Methods: Two hundred and three patients with chest pain or dyspnea who attend the hospital emergency ward were enrolled over a study period at a single academic center. PE was confirmed by multidetector computed tomography (MDCT) scans. PaCO₂, EtCO₂, and D-dimer were measured within 24 h of MDCT by capnograph. Results: The combination of P(a-Et)CO₂ gradient (cutoff >9.2 ng/ml) and D-dimer (cutoff >3011 ng/ml) with sensitivity and specificity of 30.2% and 87.2% showed a significant diagnostic value in detecting PE (area under the curve = 0.577, P = 0.045) but not alone (P > 0.05). Conclusion: As the results show, the combination of P(a-Et)CO₂ gradient and D-dimer can show an acceptable diagnostic value in detecting PE, although it suggests further research on evaluating the diagnostic value of P(a-Et)CO₂ gradient and combining it with other diagnostic criteria to achieve a definite and generalizable result.

Background: With the increasing prevalence of type 2 diabetes mellitus (DM), there is a need to assess if the elevated salivary glucose levels provide an environment conducive to the growth of cariogenic microorganisms specifically Streptocooccus mutans and Lactobacillus acidophilus. Materials and Methods: Forty-five patients were divided into three groups consisting of patients with type 2 DM with caries, patients with type 2 DM without caries and age-matched healthy nondiabetic individuals (control). Saliva samples were subjected to semiautomatic salivary glucose estimation by the glucose oxidase-peroxidase method, using the Tulip glucose estimation kit. Swabs were immediately inoculated onto Mitis Salivarius Bacitracin agar and Man Rogosa Sharpe agar. Results: In Group A, statistically significant positive correlation was found between S. mutans and salivary glucose (r = 0.858) as well as L. acidophilus and salivary glucose (r = 0.853). In Group B, a statistically significant positive correlation was found only between S. mutans and salivary glucose (r = 0.705) and not between L. acidophilus and salivary glucose (r = 0.387). The control group did not show a statistically significant correlation. Conclusion: It is established that salivary glucose levels reflect the diabetic state of an individual. The salivary glucose level predicted a 1.7 times higher caries susceptibility in a diabetic, as shown by results in this study. Salivary glucose causes an increase in the cariogenic load in diabetic patients, thus warranting a modification of the Keyes triad.

Background: There are numerous sophisticated studies which have investigated risk factors of breast cancer (BC). The purpose of this paper is to use benefits of Bayesian modeling to involve such prior information in determining factors affecting the survival of women with BC in Yazd city. Materials and Methods: The checklist included the characteristics of the patients and the factors studied. Then, from the records of patients referred to Radiotherapy Center of Shahid Ramezanzadeh, who had BC, from April 2005 to March 2012, the survival of 538 persons was recorded in the census. Data were analyzed by R software version 3.4.2, and 0.05 was considered the significance level. Results: The mean age of BC diagnosis was 48.03 ± 11016 years. The Bayesian Cox regression showed that surgery (hazard ratio [HR] =1.631 95% PI; 1.102–2.422), ki67 (HR = 3.260. 95% PI; 1.6308–6.372), stage (HR = 5.620, 95% PI; 4.079–7.731), lymph node (HR = 1.765, 95% PI; 1.127–2.790), and ER (HR = 2. 600 95% PI; 2.023–3.354) were significantly related to survival time. Conclusion: The parametric and cox models were compared with standard error, and Cox model was selected as an optimal model. Accordingly, stage, ki67, lymph node, ER, and surgery variables had a positive effect on death hazard.

Background: The present study aims to evaluate the effect of photodynamic therapy (PDT) on the thickness of segmentation layers of the retina in cases with central serous chorioretinopathy (CSCR). Materials and Methods: This was a prospective, observational study on cases with CSCR who were candidates for PDT therapy. All patients had undergone at least 1 month of conservative management without satisfactory resolution. PDT was carried out according to the safe half-dose therapy scheme. Spectral-domain optical coherence tomography was employed to evaluate the changes in morphology and segmentation of retinal layers. Patients were followed up for 3 months. Results: Twenty-seven cases (18 males and 9 females) were included. Age of the patients varied from 39 to 59 years (mean: 46.61 ± 12.48 years). Cases were followed for 92.17 ± 3.28 days. Sixteen cases had functional and anatomical improvement by the treatment. Changes in overall retinal (377.39 ± 61.36 to 323.61 ± 71.36; P = 0.004) and all outer retinal segmentation layers including outer plexiform layer (34.93 ± 10.07 to 29.25 ± 6.12; P = 0.008), outer nuclear layer (63.52 ± 30.44 to 46.44 ± 20.62; P = 0.017), and retinal pigment epithelium (40.66 ± 37.73 to 23.78 ± 29.33; P = 0.016) were statistically significant. On the contrary, inner retinal segmentation layers, especially retinal ganglion cell (RGC) layer (38.29 ± 16.63 to 37.26 ± 16.18; P = 0.387), remained statistically unchanged. Conclusion: We postulate that PDT alleviates outer retinal edema where fluid accumulation occurs mostly, whereas it does not alter inner retinal and especially RGC layer. These findings may indicate that short-term atrophy of the inner retina did not occur following PDT and may point toward safety of this method for cases with CSCR.

Background: In the subclinical hypothyroidism, T4 or T3 levels are normal and thyroid-stimulating hormone (TSH) is slightly high. Selenium deficiency can lead to thyroid dysfunction. The present study aims to investigate the effect of selenium supplementation on the thyroid hormone and anti-thyroid peroxidase antibody (anti-TPO AB) levels. Materials and Methods: In this double-blinded, randomized, placebo-controlled clinical trial, 42 patients with subclinical hypothyroidism were randomly assigned to receive 200 μg selenium or placebo for 8 weeks. In the both groups, the serum TSH and anti-TPO antibody levels were measured and assessed before and after the intervention. Results: After the interventions, the mean serum TSH reduction in the intervention and placebo groups was −10.98 ± 33.31 and −3.20 ± 38.36, respectively, which were not statistically significant. However, the mean serum anti-TPO Ab concentration increased in the intervention and placebo groups (109.81 ± 51.49% vs. 173.17 ± 96.26%), between which the difference was not statistically significant (P >0.05) despite a slight increase in the mean anti-TPO level in the intervention group. Conclusion: The results of the current study indicated that selenium supplementation has no significant effect on serum anti-TPO Ab and TSH levels in the patients with subclinical hypothyroidism. Studies with larger sample size and with different doses of selenium are needed to reach more precise results.

Paraquat is a highly toxic compound and a widely used herbicide that causes serious morbidity and mortality. The most well-known route of poisoning is oral ingestion, whereas parenteral injection of paraquat is individually uncommon. We present a case who injected paraquat in his neck in an attempt to commit suicide. His general condition got worsened gradually over 3 days. He received early hemodialysis in 4 h after self-injection and then supportive treatment in intensive care unit. Early hemodialysis helped him survive, but during hospitalization, some rare complications occurred, and unfortunately, he died after 3 months. Despite the high-risk route of poisoning, the patient survived for 3 months. Our patient was protected from renal and hepatic damage may be because of early hemodialysis but suffered from central nervous system and pulmonary damage.

Background: Dental ceramics exhibit good optical and esthetic properties due to their translucency. Feldspathic ceramic is the most widely used veneering ceramic with brittleness, which accounts for most of its failure. Hence, this study was done to evaluate and compare the flexural strength of feldspathic ceramic reinforced with zirconia-silica nanofibers in the ratio of 2.5, 5, and 7.5 wt% with conventional feldspathic ceramic. Materials and Methods: According to ISO 6872, a master die was prepared from which resin bars were fabricated with 4.0 mm in width × 1.2 mm thickness × 25.0 mm length, Zirconia-silica nanofibers were produced by sol-gel electrospinning go around with calcination and blended with feldspathic ceramic through ball milling method. The samples were prepared with 0, 2.5, 5, 7.5 wt% nanofibers reinforced ceramic. The flexural strength of the samples was evaluated using three-point bending test. Results: The flexural strength values of zirconia-silica nanofibers reinforced ceramic groups were higher than control group. There was a gradual increase in the flexural strength values of felspathic ceramic groups with increase in wt% of nanofibers. Conclusion: The flexural strength of feldspathic ceramic samples reinforced with zirconia-silica nanofibers by 5 and 7.5 wt% were statistically significant compared to control, whereas the flexural strength of 2.5 wt% was statistically insignificant compared to the control group.

Retropubic midurethral sling (MUS) is safe and effective surgery used for the treatment of stress urinary incontinence in women. Bladder neck perforation is a rare intraoperative complication. If this complication missed in intraoperative cystoscopy may have serious morbidity. A 52-year-old woman underwent a retropubic MUS. She presented with early and unusual symptoms such as suprapubic and labial cellulitis and urine leakage through the suprapubic incision 1 week after surgery which was due to a missed bladder neck perforation during surgery. In cystoscopy after MUS revealed mesh traversing the bladder neck and it was removed. The missed bladder perforation may have early and unusual symptoms and cystoscopy must be done more carefully and obsessively in patients with risk factors.

Background: Postoperative complications of open heart surgery require extensive care, especially by the patient. One of the important strategies in this regard is self-care education and one of the well-known patterns is Orem self-care model. This study aimed to investigating the effect of Orem-based self-care program on sleep quality, daily activities, and lower extremity edema in patients undergoing coronary artery bypass graft surgery. Materials and Methods: This clinical trial study was performed on 74 patients with coronary artery bypass graft surgery in Kashani Hospital in Shahrekord. The patients were randomly assigned to intervention and control groups. Data were collected using need assessment form according to the Orem model, quality of life and activity daily living questionnaire and measurement of edema by the meters. Data were analyzed using descriptive and analytical statistics with SPSS software. Results: The sleep quality score in the intervention group immediately after the intervention and 2 months after, was significantly lower in the intervention group than in the control group (P = 0.001). In the intervention group immediately after the intervention and 2 months after, the daily activity score was significantly higher than the control group (P < 0.05) 2 months after intervention, edema score in intervention group was significantly lower than the control group (P = 0.006). Conclusions: Results of the recent study showed that the implementation of the Orem-based self-care program can reduce the postoperative complications and the use of nursing patterns, such as Orem, to enhance self-care ability in patients who require long-term care can be very effective.

Background: Recently, the D-dimer biomarker has gained the researchers' attention for predicting infections. We aimed to determine the relationship between this marker and other inflammatory markers involved in orthopedic implant-associated infections. Materials and Methods: In this study, all patients diagnosed with an orthopedic implant-associated infection were investigated in 3 years. The serum level of D-dimer, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) was measured. Infection was diagnosed based on the clinical and culture results of biopsy samples. Results: The cultured microorganisms, detected in 26 patients with infections, included Staphylococcus aureus (n = 13, 50%), Staphylococcus epidermidis (n = 2, 7.7%), Klebsiella aerogenes (n = 8, 30.8%), and Pseudomonas aeruginosa (n = 3, 11. 5%). Based on laboratory findings, there was a significant difference in the CRP level and ESR (P = 0.001). Although the level of D-dimer was higher in infected patients, compared to the controls (992.6 ± 667.2 vs. 690.1 ± 250.2 ng/mL), the difference was not statistically significant. There was no significant correlation between the elevated D-dimer level and CRP level, whereas ESR had a positive correlation with the elevated D-dimer level (r = 0.6, P = 0.03). The sensitivity, specificity, and positive predictive value (PPV) of D-dimer in the prediction of infection were 65%, 57%, and 45%, respectively. Furthermore, the sensitivity, specificity, and PPV of CRP were 100%, 92.3%, and 95%, respectively, whereas the corresponding values for ESR were 85%, 69.2%, and 62%, respectively. Conclusion: Measurement of the serum D-dimer level is not efficient for the diagnosis of orthopedic implant-associated infections due to its low predictive value. Furthermore, there was no significant correlation between the serum D-dimer level and CRP.

Background: Documented streptococcal resistance to erythromycin has recently been raised. The aim of this study is to identify the molecular mechanism of erythromycin resistance among group B Streptococcus (GBS) strains and to correlate with the clinical origin of strains. Materials and Methods: A total number of 134 colonizing (n = 36), invasive (n = 36), noninvasive (n = 46), and asymptomatic (n = 16) GBS isolates were characterized by the detection of dltS gene, capsular serotyping, antibiotic susceptibility profiles using disc diffusion method, and screening of the ermB, ermTR, and mefA resistance genes. Results: The distribution of capsular serotypes was as follow: serotype III (24.6%), Ia (21.6%), V (17.9%), Ib (14.9%), II (8.9%), IV (8.9%), VI (1.5%), and VII (1.5%). From 134 GBS isolates, 51 (38%) isolates were resistant to erythromycin. The constitutive macrolide lincosamide streptogrmin B (MLSB) was the most common resistance phenotype (62.7%), followed by inducible MLSB (27.4%) and M phenotype (9.8%). Erythromycin resistance rate was higher among asymptomatic GBS strains (13/16, 81.2%). Serotype III was the most prevalent type among resistant isolates (41.1%). The ermB gene highly distributed among resistant strains (64.7%), followed by ermTR (21.5%) and mefA (9.8%). The ermB gene was related to constitutive MLSB phenotype (84.3%, P < 0.05) and serotypes III (61.9%), Ib (87.5%), and V (83.3%). All M phenotype strains harbored mefA gene and were in association with serotype Ia (90%). Conclusion: The current study suggests that ribosomal modification with erm genes is the main mechanism of erythromycin resistance. Because of relatively high prevalence of erythromycin resistance, double disc test highly recommended for GBS disease treatment and intrapartum prophylaxis among penicillin intolerant patients in our region.

Primary breast lymphomas are uncommon tumors and account for <1% of all malignant neoplasms of the breast. They are almost always of non-Hodgkin type, with B-cell lymphomas being the most common subtype. Anaplastic large cell lymphoma (ALCL) is a rare T-cell lymphoma that can involve the breast. Most of the articles in the literature describe ALCL in association with breast implants. We present a 48-year-old woman with a left breast enlargement and no history of an implant. Microscopic sections showed a high-grade CD30-positive lymphoid neoplasm with frequent giant cells, which turned out to be a primary ALCL of the breast, giant cell-rich pattern. To our knowledge, no cases of primary ALCL, giant cell-rich variant, have been reported in the breast in the absence of an implant making our case unique.

The COVID-19 pandemic has raised concerns among physicians and patients with autoimmune disorders about how this viral infection affects the patients receiving immunosuppressive drugs. There are speculations about a higher incidence and severity of COVID-19 in patients receiving a variety of immunosuppressant drugs. However, we reported the rapid recovery from COVID-19 in a 67-year-old male with granulomatosis with polyangiitis who did not experience severe symptoms of the COVID-19 as expected, despite having a history of serious lung involvement due to the autoimmune disease. He received conventional medications to treat COVID-19, though he had been receiving rituximab and corticosteroids before the onset of COVID-19 symptoms. Prevention of the cytokine storm caused by SARS-CoV-2 infection owing to taking the immunosuppressive drugs (rituximab and corticosteroids) could be a reason for these unexpected observations. Therefore, this case showed that taking immunosuppressive drugs is unlikely to be directly related to the increased severity of COVID-19.

Triage becomes necessary when resources and time are not sufficient to provide the best possible services to all patients. This condition is more common in situations with a large number of casualties, like infectious epidemics. What is apparent is that, in the case of a widespread outbreak of infectious disease, hospitals are on the front lines of infected patient admission and treatment. Since the training of health-care workers is one of the most important pillars of preventive measures in controlling this pandemic, this study was conducted with the aim of expressing the principles of triage of infectious disease epidemic with a COVID-19 approach.

Background: Artemisia kermanensis Podl. is a green aromatic perennial shrub that belongs to the family Asteraceae and it grows widely in central deserts and south-eastern mountains of Iran such as Taftan Mountain in Sistan and Baluchestan Province. Artemisia species have been used traditionally as a remedy for various feverous diseases, including malaria, treatment of colds, infections, parasites, inflammations of the liver, as well as dyspepsia, diabetes, hypertension, and so many other conditions. Materials and Methods: Air-dried A. kermanensis extraction from all parts of the plant was done using different organic solvents. The methanolic extract was selected for isolation of flavonoids, using thin-layer chromatography. The chemical structures of the isolated compounds were determined based on analysis of mass and nuclear magnetic resonance spectra. Results: Two flavone aglycones were isolated and identified for the first time from this plant's methanolic extract, including 5,7-dihydroxy-3',4',6-trimethoxyflavone (eupatilin) and 5,7,3'-Trihydroxy-6,4',5'-trimethoxyflavone. Conclusions: Eupatilin is known for its anticancer, antioxidant, and anti-inflammatory activities. In future researches on A. kermanensis, as a rich source of these flavone compounds, it is wise to investigate for the proven eupatilin's biological activities that have been mentioned.

Background: The aim was to assess the effect of vasopressin in reducing the time of surgery, amount of bleeding, and fluid deficit during hysteroscopic myomectomy of submucosal myoma from 2016 to 2018. Materials and methods: This study was conducted as a prospective, randomized, single-blinded clinical trial on the premenopausal women ranged from 18 to 62 years' old. A number of 80 patients were randomly assigned to each arm of the study according to random consecutive numbers. The control group (n = 40) of patients underwent conventional hysteroscopic myomectomy without vasopressin and the case group (n = 40) underwent hysteroscopic myomectomy with the injection of diluted vasopressin. Measured outcomes were time for myomectomy, fluid deficit, inflow volume, visual clarity, and postoperation hemoglobin level. Results: The mean time of myomectomy was 38.1 and 77.38 min in vasopressin and control groups, respectively (P < 0.001). The mean inflow volume was 2800 and 4100 in vasopressin and control groups, respectively (P = 0.029). The visual clarity score was 8.5 and 6.5 in the vasopressin and control groups, respectively (P < 0.001). Conclusions: The injection of vasopressin during hysteroscopic myomectomy is effective in the management of fluid deficit, time of surgery, and improvement of visual clarity.

Background: The surface of endothelial cells is covered with cell adhesion molecules including E-selectin, intercellular adhesion molecule-1 (ICAM-1), and vascular cell adhesion molecule 1 (VCAM-1) that mediate the adhesion and extravasation of leukocytes and play a pivotal role in inflammatory response. The aim of this study was to investigate the role of expression of adhesion molecules in inflammatory bowel disease (IBD) patients, irritable bowel syndrome (IBS) patients, and normal colonic mucosa. Materials and Methods: IBS and IBD patients along with normal colonic mucosa were recruited in the study. In all groups, two biopsies were taken from each of the three anatomical sites (terminal ileum, cecum, and rectum). Three monoclonal antibodies, E-selectin mAb, VCAM-1 mAb, and ICAM-1 mAb, were applied for immunohistochemical analysis. Results: In IBD patients, the expression of intensity of E-selectin, VCAM-1, and ICAM-1 was found decreased, at least in cecum and rectum, in comparison with IBS patients and controls (P < 0.001, P < 0.005, and P < 0.007, respectively). Comparison of the expression of intensity of the aforementioned molecules in IBS patients and controls revealed significant augmentation at the cecum and rectum of IBS patients. Conclusions: The expression of adhesion molecules appeared lower in IBD patients compared to IBS patients and controls. In addition, the expression of adhesion molecules appeared higher in IBS compared to the control group. Therefore, it could be hypothesized that the expression of adhesion molecules could be considered as an early event in the process of proinflammatory IBS group and may be other factors play a crucial role in the process of intestinal inflammation in IBD patients.

Background: Fentanyl is a short-acting drug used to induce anesthesia. Here, we aimed to compare the two doses of ketamine to prevent fentanyl-induced cough in children under general anesthesia. Materials and Methods: This is a randomized, clinical trial which was performed in 2019 in Imam Hossein Hospital in Isfahan, Iran. The study population consisted of children between 6 months and 2 years who were candidates for general anesthesia. Patients were randomized into three groups, each containing 31 patients. Groups 1 and 2 received 0.1 mg/kg and 0.2 mg/kg intravenous ketamine, respectively, 1 min before fentanyl injections. Group 3 received the same volumes of normal saline 0.9%. Patients were observed and evaluated for the incidence and intensity of coughs 1 min and 3 min after fentanyl injections. Results: We showed that the frequency of coughs 1 min after fentanyl injection was significantly lower in Group 2 compared to other groups (P < 0.001). Three min after fentanyl injection, the frequencies of coughs were significantly lower in Groups 1 and 2 compared to Group 3 (P < 0.001). We also showed that the intensity of coughs was significantly lower in Group 2 compared to other Groups 1 and 3 min after fentanyl injection (P < 0.001). Conclusion: The administration of 0.2 mg/kg ketamine is more effective than 0.1 mg/kg dosage in the prevention of fentanyl-induced cough. We also showed that this method could bring more stable hemodynamics and oxygenation saturation inpatients. The comparison of the two dosages was a novel issue in the recent literature.

Background: Congenital adrenal hyperplasia (CAH) is an autosomal recessive disorder caused by impaired steroidogenesis. Glucocorticoid treatment with increased androgens may lead to cardiovascular and metabolic effects in these patients. In this study, we investigated the relationship between cardiovascular risk factors and androgen levels in children and adolescents with CAH due to 21 hydroxylase deficiency. Materials and Methods: A cross-sectional study of 78 patients (37 boys and 41 girls) with CAH aged 3–17 years. Anthropometric, body mass index (BMI), systolic (SBP), and diastolic (DBP) blood pressure were measured. Fasting blood glucose with plasma insulin and lipids were measured, and insulin resistance (HOMA-IR) calculated using the homeostasis assessment model. Furthermore, testosterone, Dehydroepiandrosterone sulfate (DHEAS), and 17-Hydroxyprogesterone (17OHP) were investigated. Results: The mean SBP and DBP were 112.01 ± 19.13 and 69.77 ± 7.56, respectively. The mean of HOMA-IR in patients was 2.25 ± 1.46. The frequency of patients with overweight and High HOMA index were, respectively, 33.3% and 29.3%. The correlation analysis between clinical characteristics and androgen serum levels showed that DBP and BMI had a significant positive correlation with 17OHP. The median regression analysis showed, only DBP in the adjusted model had a significant positive effect with 17OHP level (P < 0.05), and no significant relationship was observed for other characteristics. Conclusion: A significant association was found between BMI and DBP with serum concentrations of 17-OHP, suggesting that elevated 17-OHP can lead to an increased risk of cardiovascular disorders in children and adolescents with CAH.

Background: Boswellia species have been used for treatment of chronic inflammatory disease. Several studies have documented the anti-inflammatory effect of Boswellic acids (BAs) after systemic administration. This study was aimed to evaluate the effect of some skin penetration enhancers on topical anti-inflammatory effect of BAs in rats. Materials and Methods: Male Wistar rats weighting 180–220 were used. Anti-inflammatory activity was assessed using carrageenan test. BAs dissolved in ethanol, propylene glycol 2%, 5%, olive oil and applied topically. Menthol, D-limonene, or eucalyptus oil 0.5%, 1% were also tested as other skin penetration enhancers and applied topically 30 min prior to subplantar injection of carrageenan into the right hind paw of rats. The volume of the paw was measured at 0 and 4 h after carrageenan with a digital plethysmometer and the difference was used as an index of inflammation. Piroxicam gel was used as a standard drug. Results: A 4% ethanolic solution of BAs showed significant anti-inflammatory effect. Propylene glycol (2% and 5%) in alcohol did not change the effect. Olive oil also enhanced penetration of BAs. Menthol 0.5%, 1% and D-limonene 0.5%, 1% did not show any significant change compared to olive oil alone. In the present study, eucalyptus oil 1% in olive oil was known as the best carrier for transdermal delivery of BAs. Conclusion: BAs have considerable topical anti-inflammatory effects and olive oil alone or especially in combination with eucalyptus oil can be promising vehicles for skin penetration of topical BAs.

Background: This study aimed at investigating the effect of home-based physical activity schedule on the quality of life (QOL), sleep quality, and mood of the elderly at risk of depression as compared to the control group. Materials and Methods: The open-label randomized controlled trial was performed on 61 elderly people at risk of depression who were divided into two groups. In addition to routine care provided by the health-care center (relaxation techniques), the elderly in the intervention group were given a home-based physical activity booklet. The control group only received the routine care of the health-care center. Moreover, before and after the intervention, the results of the QOL questionnaire, petersburg sleep quality questionnaire index (PSQI), and depression questionnaire were assessed and recorded. Results: The depression scores in the 1^st and 3^rd months during the intervention and 1 month after the intervention were significantly lower in the intervention group with the means of 3.60 ± 3.91, 2.03 ± 2.43, and 2.66 ± 3.37 as compared with the control group with the means of 5.39 ± 2.88, 4.96 ± 2.77, and 5.13 ± 3.14, respectively (P < 0.05). Furthermore, the QOL and total PSQI scores in the physical and mental dimensions in the 3^rd months during and 1 month after the intervention were higher in the intervention group as compared with the control group (P < 0.05). Conclusion: According to the findings of the study, the addition of home-based physical activity schedule to the routine care of the elderly can play a significant role in reducing the severity of their depression and improving their physical–psychological quality and sleep quality.

Background: The detection of circulating tumor cells (CTCs) is prognostic during the disease in women with metastatic breast cancer. Integrins are key role players in nearly every step of cancer progression. In this study, we aimed to analyze integrin alpha6beta4 expression on CTCs isolated from blood samples of patients with advanced breast cancer. Materials and Methods: In this single-center study, peripheral blood samples from 23 breast cancer patients were obtained and analyzed for the presence of CTCs by EasySep™ Direct Human CTC Enrichment Kit combined with subsequent immunocytochemical staining of anti-cytokeratin and anti-epithelial cell adhesion molecules, and β4 integrin on CTCs. Data were correlated with clinicopathological parameters. Results: CTCs were detected in 100% of the patients. The ratio of integrin β4+ CTC was 61% ± 8% of total CTCs. No significant correlation between histopathological parameters and CTC detection was found. Conclusion: Our results demonstrated the importance of α6 β4 integrin expression on CTCs in distant metastasis.

Background: Patients with heart failure are one of the high-risk groups for coronary artery. Distance education of self-care behaviors can be effective in preventing the disease. The aim of this study was to investigate the effect of social networks in explaining the awareness of cardiovascular patients' self-care behaviors toward COVID-19. Materials and Methods: In the present survey study, 227 patients with a history of heart failure were selected from Shahid Rajaei Hospital in Tehran by the available sampling method (May to July 2020). Data collection tools were the standard European Self-Care Behavior Questionnaire for heart failure and the Dorty Elizabeth Orem self-care model. Data were analyzed using SPSS Version 22. Results: The results of the Pearson correlation coefficient showed a positive and relatively strong linear relationship between the variable of the degree of persistence in the use of networks with the eight dimensions of self-care behavior except psychological emotion control (r = −0.39, P = 0.315). Furthermore, a significant weak inverse relationship between the dimension of “cooperation with physicians and treatment staff” (r = −0.22, P = 0.129). Moreover, psychological support (r = −0/034, P = 0.446) was observed with the use of networks. Multivariate regression analysis revealed that the type of activity and participation in networks has a greater share and effect in increasing the score of self-care behavior of 0.55. Conclusions: Since the use of networks has a positive effect on patients' self-care behavior, the use of these networks is recommended as a community-based approach in the health system and to improve health and health outcomes.

Background: Selective norepinephrine-serotonin receptor inhibitors (SNRIs) such as duloxetine have already shown beneficial effects on symptoms in irritable bowel syndrome (IBS) patients. The purpose of the present investigation was to assess the efficacy of duloxetine in the symptom and quality of life improvement in diarrhea predominant-IBS (IBS-D) patients. Materials and Methods: IN a randomized, double-blind and placebo-controlled study, sixty patients diagnosed with IBS-D (ROM-IV criteria), referred to the gastrointestinal clinic of Rasoul-e-Akram Hospital of Iran university of medical sciences, randomly assigned in the treatment groups, group A: patients who received 135 mg mebeverine tablet twice a day combined with 30 mg duloxetine capsule per day and group B, who received the same regimen, except for placebo capsule once per day instead of duloxetine for twelve weeks. The assessment was performed using the IBS severity index, and IBS quality of life questionnaire (IBS-QOF) at baseline, and weeks 4, 8, and 12 after beginning the treatment. Drug adverse effects and compliance to treatment were evaluated every 2 weeks after starting the treatment. Results: Sixty patients completed the trial. The duloxetine group showed significantly greater improvement on the IBS symptoms (P < 0.001), and the IBS-QOF (P < 0.001) in comparison to the placebo group at the endpoint. Conclusions: This study showed that adding duloxetine to mebeverine is safe with good efficacy on symptoms and QOL improvement in IBS-D patients. Besides, this study showed that 12 weeks' treatment duration is significantly more effective than 4 weeks' treatment, and drug adverse effects are more prominently seen in the first 2 weeks of treatment.
