Background: The aim of this study was to investigate the frequency of poisoning mortality in the 5-year period of 2014–2019 in Isfahan Khorshid Hospital, Iran. Materials and Methods: This study is a cross-sectional descriptive analytical study, which was performed in 2020. The demographic and clinical data about the patients were extracted from the patients' files and were then analyzed. Results: The number of deaths due to poisoning in the study period was 264, and the mean age of the deceased was 42.33 ± 20.097. One hundred and ninety-three (73.1%) patients were male. The frequency of deaths in the poisoning ward was 0.84%. The causes of death were accidental overdose (73, 26.9%), suicide (155, 63.2%), accidental use (18, 7.3%), and homicide in one patient. The mean age, time between exposure of toxin until death and history of addiction, substance use, and suicide in men patients was significantly higher than women (P < 0.05), however, such significant results were observed in married when compared with single patients. The differences between the two genders based on the type of toxic substance were statistically significant (P < 0.001). The most common causes of death were pesticides poisoning (n = 121), especially paraquat (n = 48) and Aluminum phosphide (n = 45), and multidrug poisoning (n = 48). Conclusion: In this study, we showed that the death rate due to poisoning in our center was lower than other centers. The highest number of poisoning was in men as well as married patients. It is also recommended that more serious educational and preventive strategies should be used in this regard.

Background: Acute lymphoid leukemia (ALL) is the largest subset of hematologic malignancies, accounting for approximately 70%–80% of childhood leukemia, and is most common at age 4 years. The aim of this study was to define the frequency of chromosomal abnormalities in pediatric ALL. Materials and Methods: In this 11-year retrospective study, we investigated 99 patients which referred to our department due to ALL from 2010 to 2020. The age group of the patients ranged from 6 months to 14 years with a mean of 6.71 ± 4.09 years. Clinical and diagnostic findings were extracted from patients' medical records. Results: We showed cytogenetic abnormalities of 99 pediatric ALL patients, including 78 pre-B-ALL, 9 common B-ALL, and 12 T-ALL cases. The 5-year overall survival rate (OSR) and event-free survival (EFS) of all cytogenetic abnormalities (n = 99) were 48% and 43%, respectively. There was a significant relationship between the two cytogenetic abnormalities, hypodiploidy and t(9;22), with death (P < 0.05). On comparing the subjects with normal cytogenetics to the other cytogenetic abnormalities, EFS was significantly low for hypodiploidy (P = 0.0163, hazard ratio = 0.5308) and t(9;22) (P = 0.0131, hazard ratio = 0.4908), while other cytogenetic abnormalities did not have a statistically significant difference in EFS. Conclusions: Our results emphasized the importance of the cytogenetic findings in evaluating the survival outcomes, which allows identifying a variety of OSR and EFS, because some of the cytogenetic abnormalities may interfere with the death and prognosis.

Background: Obesity, Vitamin D (VD) deficiency, and infertility are important ubiquitous issue; however, the association of obesity and serum VD levels with abnormal sperm is unclear and inconclusive. The current study investigated the correlation of obesity and serum VD levels with sperm DNA integrity and sperm parameters in normozoospermia men. Materials and Methods: Semen and blood samples from 64 men were divided into two groups: obese and nonobese men based on body mass index (BMI). Sperm motility and viability were determined by computer-aided sperm analysis and eosin-nigrosin staining. DNA fragmentation, determined by sperm chromatin dispersion method. VD concentrations were assessed by the Elisa technique. Results: Serum concentration of VD levels in the obese group was significantly lower than nonobese men (P < 0.05). Sperm motility was significantly reduced in the obese group in comparison to nonobese (P < 0.05). Rapid progressive motility was statistically lower in obese men compared with the nonobese group (P < 0.05). Sperm count and morphology were not statistically significant in both groups. Sperm viability in the nonobese group was significantly decreased in comparison to obese group (P < 0.05). DNA integrity was significantly higher in the obese group as compared with nonobese (P < 0.01). Conclusion: VD deficiency in the obese group showed decreased sperm motility, increased DNA damage, and viability. Adverse consequences of obesity and the possible effect of BMI infertility treatment must be discussed with counseling couples interested in assisted reproductive techniques outcomes, especially in men without any unknown cause.

Background: Microsatellite instability (MSI) in colorectal cancer (CRC) patients is considered as a diagnostic and prognostic marker. MSI is a consequence of mismatch repair deficiency which is evaluated using the different microsatellite markers on the whole genome. In this pilot study, the diagnostic value of a novel triplex panel including three mononucleotide markers has been evaluated in comparison to the standard Promega kit for MSI testing in CRC patients with Amsterdam II criteria. Materials and Methods: DNA extracted from tumors and normal Formalin-Fixed Paraffin-Embedded (FFPE) tissues of index cases from 37 HNPCC (Hereditary non-polyposis colorectal cancer) families were evaluated for MSI state. Primer design for three markers, including BAT25, ACVR2, and TGFBR2, was performed using 19 nucleotides of the M-13 phage. The instability of each marker was assessed through fragment analysis in comparison with Promega kit markers for all patients. The sensitivity and specificity of each marker have been calculated. Results: The comparative evaluation of MSI in both tumors and normal adjacent FFPE tissues demonstrated a separate sensitivity as 100%, 83.3%, and 76.9% for BAT25, ACVR2, and TGFBR2, respectively, and 100% sensitivity in the form of a triplex. Moreover, the specificity for each of these three markers in MSI testing was estimated as 100%, separately and in the form of the triplex in comparison with the Promega pentaplex standard Kit. Conclusions: A high sensitivity and specificity for the novel triplex panel in MSI-testing were estimated among Iranian patients. More studies are recommended to confirm this panel as a diagnostic kit for MSI testing.

Background: Glutamate is an important excitatory neurotransmitter in the pedunculopontine tegmental (PPT) nucleus. The cardiovascular effect of glutamate and its non-N-methyl-D-aspartate (NMDA) receptor in the PPT is unknown; therefore, we evaluated glutamate and its non-NMDA receptor on cardiovascular parameters in normotensive and hypotensive induced by hydralazine (HLZ) in rat. Materials and Methods: After anesthesia, the femoral artery was cannulated for recording of cardiovascular parameters. Microinjection of drugs was done stereotaxically. L-Glutamate (L-Glu) and 6-cyano-7-nitroquinoxaline-2,3-dione (CNQX) (an antagonist of nonNMDA receptor) were microinjected into the PPT in normotensive and HLZ hypotensive rats. Changes (Δ) of mean arterial pressure (MAP), systolic blood pressure (SBP), and heart rate (HR) were obtained and compared with the control group. Results: In normotensive rats, L-Glu significantly increased SBP and MAP (P < 0.001) and decreased HR (P < 0.01), whereas CNQX alone did not significantly effect. Coinjection L-Glu + CNQX significantly attenuates the cardiovascular effect of L-Glu (P < 0.05 to P < 0.01). In hypotension induced by HLZ, SBP and MAP significantly decrease but HR did not change. In HLZ groups, L-Glu significantly improves (P < 0.05) and CNQX deteriorated hypotension induced by HLZ (P < 0.05). Coinjection of L-Glu + CNQX also attenuates the effect of L-Glu on Δ MAP and Δ SBP. In hypotension, ΔHR induced by L-Glu was significantly higher than CNQX (P < 0.01). In L-Glu + CNQX group, ΔHR also was lower than L-Glu (P < 0.05). Conclusion: Our findings revealed that glutamatergic system of the PPT in both normotensive and hypotension induced by HLZ plays a pressor with bradycardic responses that partly mediated by non-NMDA receptor.

Background: This study aimed to determine the current EPIYA motifs of the cagA gene in Helicobacter pylori isolates from patients with gastric disorders, and evaluate the association between these patterns and the clinical outcome of H. pylori infection in different geographical regions of Iran. Materials and Methods: We examined 150 patients with gastrointestinal disorders from the central and eastern regions of Iran. The detection of H. pylori and screening of cagA was performed by polymerase chain reaction (PCR). The pattern of the motifs was determined by PCR followed by sequencing. Results: The overall prevalence of H. pylori was 66.3% in eastern (Mashad) and 50.6% in the central (Isfahan) part of Iran. The frequency of cagA-positive strains in Mashad and Isfahan were 63.4% and 56.7%, respectively. The pattern of EPIYA motif was as follows: 43 (79.6%) ABC, 7 (12.9%) AB, 4 (7.4%) ABCC, and one (1.9%) ABCCC. We also identified a novel EPIYA C sequence motif which showed association with gastric cancer (GC). The relationship between the frequency of specific EPIYA motifs and GC was statistically significant (P < 0.05). Conclusions: This is the first report for the determination of the cagA EPIYA motif of H. pylori in the Northeast and center of Iran. The prevalence of cagA positive H. pylori between the two regions was significant (P ≤ 0.05). All isolates of the H. pylori cagA were western type (ABC). The increase in the number of EPIYA-C repeats was associated with GC (P ≤ 0.01).

Background: Wrist function has a significant impact on quality of life, which is why restoring normal wrist movement after surgery is so important. Due to the COVID-19 pandemic, and the restrictions imposed on “face-to-face” visits, using smartphones has become more important in tracking patients. The main purpose of this study was to determine the accuracy of telemedicine in following up patients who had undergone distal radius fracture operation. Materials and Methods: From February to October 2020, 126 patients between 20 and 60 years old were randomly selected at our orthopedic trauma center. All patients were visited in person by an orthopedic surgeon in the morning (control group) and again all of them were visited online via smartphone in the evening by another orthopedic surgeon (case group). Both visits were done at regular intervals in the 2^nd, 6^th, and 12^th weeks after surgery. Patients were evaluated for extremity function outcomes and joint range of motion. Results: The two groups were similar in terms of mean Patient-Rated Wrist Evaluation score and Disabilities of the Arm, Shoulder, and Hand score and did not show a statistically significant difference (P < 0.05). There was no significant difference in wrist range of motion measurements between the two groups (in-person visits and smartphone visits) during the follow-ups (P > 0.05). Conclusion: Changes in wrist range of motion after surgery can be assessed with high accuracy using smartphone applications and this method can be considered as a proper alternative to frequent in-person visits to evaluate postsurgical wrist condition.

Background: Toxoplasmosis is a disease caused by Toxoplasma gondii, and one-third of the world's population has T. gondii antibodies. Due to this issue, the aim of this study was to assess the mean prevalence and odds ratios of T. gondii infection and epidemiological features of neonatal infection worldwide. Materials and Methods: We performed a meta-analysis and systematic review of published studies reporting T. gondii infection using the PubMed, MEDLINE, Web of Science, EMBASE, and Scopus electronic databases through January 1999 to December 2020, regarding diagnostic tests, and prevalence data of infection among the newborn population. The pooled prevalence of T. gondii with a 95% confidence interval (CI) was calculated using the random-effects models. Results: A total of thirty eligible articles were included. The estimated global prevalence rate was 44% (95% CI: 29%–0.58%); the highest prevalence rate was in America 47% (95% CI: 30%–64%), followed by Europe 41% (95% CI: 26%–57%) and Asia 33% (95% CI: 4%–61%). In this study, despite our careful analysis of possible modifiers, the heterogeneity was significant (P = 0.000). The publication bias was not significant based on the results of Egger's (P = 0.918) and Begg's tests (P = 0.230). Conclusion: Based on the results of this study, T. gondii infection can be a serious concern in newborns around the world. Therefore, further research is needed to provide better strategies to screen and diagnose T. gondii infection in neonates and determine the risk factors associated with the prevalence of infection in neonates worldwide.

Background: Considering the side effects of common drugs used to treat polycystic ovary syndrome (PCOS), researchers have turned their attention to natural compounds, including medicinal plants. Foeniculum vulgare has estrogenic properties and has been traditionally used to treat gynecological disorders. Bunium persicum has medical aspects that have not yet been evaluated, so the aim of this study was to evaluate the effects of combination therapy with these extracts on clinical symptoms of women with PCOS. Materials and Methods: In this double-blind clinical trial study, 70 women with PCOS referred to infertility clinics, were selected and randomly divided into two groups. The intervention group received B. persicum capsule 60 mg plus F. vulgare capsule 25 mg) twice daily for 4 months and the control groups received routine intervention. Before and after the intervention, levels of luteinizing hormone (LH), follicle-stimulating hormone, progesterone, prolactin, testosterone and dehydroepiandrosterone sulfate (DHEAS) levels, hirsutism score, and menstrual pattern were recorded and endometrial thickness and follicle count were determined by ultrasound. Data were analyzed by the SPSS21 software. Results: Treatment with B. persicum and F. vulgare extracts significantly decreased LH and DHEAS levels, hirsutism score, and significantly increased menstrual duration compared to the control group. Before the intervention, 5.7% of the intervention and control groups had the normal menstrual pattern, while after the intervention 31.4% of the intervention group and 25.7% of the control group had the normal pattern. Conclusion: Regarding the effect of these extracts combination and because they have no side-effects, which is a great advantage over chemical drugs, using of these plants recommend.

Background: Obesity hypoventilation syndrome (OHS) is associated with increased mechanical load on respiratory system. Here, we aimed to investigate and evaluate the effects of noninvasive ventilation (NIV) on physical and mental status of patients with OHS. Materials and Methods: The current study is an observational study that was performed in 2020 on 50 patients with OHS in Isfahan, Iran. Beck's Depression Inventory (BDI-II) and Hospital Anxiety and Depression Scale (HADS) questionnaires were also filled for all patients assessing their depression levels that were confirmed by psychiatrists. PO₂ and PCO₂ of patients were evaluated using venous blood gas (VBG) before interventions. Patients with a definite diagnosis of OHS and depression entered the study and underwent treatments with NIV. One month after the interventions with NIV, the blood gases of patients were evaluated using VBG and BDI-II, and HADS questionnaires were also filled for all patients, evaluating their depression. Results: The mean age of the subjects was 63.5 ± 13.5. The mean blood oxygen after the use of NIV in patients with OHS increased significantly (P = 0.001). The mean of carbon dioxide after using NIV in patients with OHS decreased significantly (P = 0.001). Based on the BDI-II and HADS scales, the mean score of depression after using NIV decreased significantly (P = 0.001 for both). Conclusion: NIV therapies are associated with improvements in blood oxygen and CO₂ of patients with OHS. The levels of depression also decreased after treatments that were confirmed by psychiatrists.
