Mohammad Reza Sharbafchi, Mostafa Heydari
Adv Biomed Res
2017, 6:122 (21 September 2017)
DOI
:10.4103/abr.abr_283_16
PMID
:28989915
Background:
Historically, substance misuse has been a serious problem faced by worldwide military personnel. Some research showed that military personnel have higher rates of unhealthy substance use than their age peers in the general population. These problems have serious consequences and may lead to significant military difficulties in the field of readiness, discipline, and mental or physical health. In this review, we gathered various methods for prevention, diagnosis, and treatment of substance use disorders and suggested a comprehensive plan for Iran Armed Forces to improve existing services.
Materials and Methods:
This article is a narrative review study, which was carried out on 2016. A careful literature review was performed between January 1970 and April 2016 on several national and international databases. Articles were screened according to the following inclusion criteria: (1) review articles about prevention and treatment protocols, (2) executive guidance, (3) cohort articles about risk factors of addiction, and (4) randomized controlled trials about prevention or treatment of substance use disorders in army service members. After screening by title and abstract, 130 articles selected of 832 founded articles, and after quality assessment, finally, 63 articles included in the review.
Results:
There is a necessity to manage substance use disorder through prevention, screening, and then referral to proper services for diagnosis and treatment. Urinalysis programs for screening are cost-effective and should be considered as a main method. Effective treatment includes both behavioral and pharmacological methods.
Conclusions:
The ideal prevention program will include multiple and mutually reinforcing evidence-based universal, selective, and indicated attempts at both the individual and environmental levels. The implementation of screening and treatment strategies needs strict rules and national guideline for the comprehensive management of substance use disorders in army.

DOI
:10.4103/abr.abr_249_16
PMID
:28989914
Background:
This study aims to evaluate the incidence of stroke, ischemic heart disease (IHD), and cardiovascular disease (CVD) mortality in clusters containing hypertension (HTN), clusters containing diabetes (diabetes mellitus [DM]), cluster with both HTN, DM, and cluster without HTN, DM in patients with metabolic syndrome (MetS).
Materials and Methods:
The association between MetS and outcomes was examined in 2257 patients with MetS that were divided into four groups includes patients with MetS with hyperglycemia (Cluster 1), patients with MetS with HTN (Cluster 2), patients with MetS with HTN and hyperglycemia (Cluster 3) and patients with MetS without HTN and hyperglycemia (Cluster 4). To assess the risk ratio and incidence of CVA, myocardial infarction, and mortality with the use multivariate Cox proportional hazards models.
Results:
As it shown the lowest prevalence of events was in Cluster 1 and against in Cluster 3 the prevalence of stroke with 34 (38.2%) cases and the prevalence of IHD and CVD mortality in Cluster 2 with, respectively, 168 (54.7%) and 51 patients (49%) had the most frequencies (
P
< 0.001), and hence that the lowest prevalence of events was seen in Cluster 1, but stroke in Cluster 3 with 34 cases (38.2%) and the prevalence of IHD and CVD mortality in Cluster 2, respectively, with 168 (54.7%) and 51 patients (49%) had the most frequencies (
P
< 0.001).
Conclusion:
More intensive changes in lifestyle and management protocols may be required in these patients for controlling the components of the syndrome, with the aim of preventing not only type II diabetes and CVD but also ischemic cerebrovascular events.

Efficacy Comparison of Divided and Infusion Intravenous Pantoprazole Methods after Endoscopic Therapy in Patients with Acute Gastrointestinal Bleeding
Amin Motiei, Vahid Sebghatolahi
Adv Biomed Res
2017, 6:120 (21 September 2017)
DOI
:10.4103/abr.abr_59_16
PMID
:28989913
Background:
Intravenous pantoprazole administration in patients with severe bleeding under urgent endoscopic therapy is effective. Furthermore, its infusion dose is useful to control bleeding; however, it is not economical. In this study, clinical outcomes and intravenous infusion of pantoprazole after endoscopic therapy plus efficacy of infusion dosage and divided doses are compared.
Materials and Methods:
This prospective, comparative study conducted on 18 adult (>18 years) patients referred to Al Zahra Hospital for hematemesis and melena bleeding who underwent endoscopic treatment with pantoprazole which divided into two groups of forty patients. First group received intravenous infusion for 80 mg and 8 mg/h. The second group received intravenous infusion with divided doses as 40 mg twice daily for 3 days. Clinical outcomes such as rebleeding, duration of hospitalization, amount of blood transfused, and mortality within 3 days after endoscopic treatment were collected and analyzed by SPSS software (version 20) using independent
t
-test, Chi-square test, and Fisher's exact test.
Results:
Duration of hospitalization in the pantoprazole infusion group was 5.42 ± 4.62 days, with three patients (7.5%) having rebleeding, and in the divided pantoprazole group was 5.90 ± 3.08 days, with four patients (10%) having rebleeding, and overall, only one person died in the divided pantoprazole group (2.5%) out of eighty patients. No significant difference was observed between two groups in terms of clinical outcomes (
P
> 0.05).
Conclusion:
Regarding to results, it can be stated that both methods with specified dosage had significant impact on improvement of hematemesis and melena. Furthermore, due to lower costs, low dose of pantoprazole in divided approach as 40 mg/12 h is proposed.

Karim Nasseri
Adv Biomed Res
2017, 6:119 (21 September 2017)
DOI
:10.4103/abr.abr_265_16
PMID
:28989912
Background:
The amount of sedation and muscle relaxation of the jaw may have an impact on complications caused by laryngeal mask airway (LMA). The aim of this study is to evaluate the effect of low-dose Atracurium on conditions of insertion, complications, and hemodynamic responses to LMA insertion following induction of anesthesia with propofol, in patients undergoing cataract surgery.
Patients and Methods:
In this double-blind randomized clinical trial study, 60 patients were randomly divided into two groups. Initially, the patients in the study group received 0.15 mg/kg intravenous injection of atracurium, and the patients in the control group received 2 ml of intravenous injection of normal saline, after which anesthesia in both groups were induced with midazolam, fentanyl, lidocaine, and propofol. The amount of jaw relaxation, ease of insertion, and the time needed for insertion, hemodynamic responses and complications of LMA insertion were evaluated.
Results:
Jaw relaxation and ease of LMA insertion in the study group was significantly better than that of the control group (
P
= 0.02). Average time needed for LMA placement in the study group (5/06 ± 0.52 second) was significantly lower than the control group (5/76 ± 0.67 second) (
P
= 0.001). Hemodynamic response to LMA insertion was similar in both groups. Sore throat at recovery and 24 h after surgery in the control group was significantly higher than that of the study group (3/30 vs. 10/30) (
P
= 0.01).
Conclusions:
Using low doses of atracurium decreases the time needed for LMA insertion and sore throat after the operation. Atracurium also increases jaw relaxation and facilitates the placement of LMA.

Cobra Payghani, Fatemeh Khani, Aryan Rafiee Zadeh, Parham Reisi, Hojjatallah Alaei, Bahman Rashidi
Adv Biomed Res
2017, 6:118 (21 September 2017)
DOI
:10.4103/abr.abr_267_16
PMID
:28989911
Background:
There is an increase in inflammatory and a reduction in anti-inflammatory cytokines in multiple sclerosis (MS). Considering the role of thyroid hormones in the development and regulation of both neural and immune systems, the aim of this study was to evaluate the effects of levothyroxine on serum concentrations of interleukin-10 (IL-10) and interferon gamma (IFN-γ) in animal models of MS.
Materials and Methods:
To induce demyelination in male Wistar rats, lysolecithin was injected into the optic chiasm. Then levothyroxine was injected intraperitoneally (20, 50, and 100 μg/kg) for 21 days. Serum levels of cytokines were measured by enzyme-linked immunosorbent assay at 7, 14, and 21 days after that.
Results:
The results showed that injection of lysolecithin to the optic chiasm only increased serum concentrations of IL-10 compared to the sham group (
P
< 0.05) at 7
th
day, but this increase was prevented by all doses of levothyroxine. IFN-γ was decreased significantly (
P
< 0.001) 21 days after. Comparing to the sham group at all sampling time and with respect to the MS group at the days 7 and 21, levothyroxine decreased serum concentrations of IFN-γ significantly.
Conclusion:
The results showed that thyroid hormones probably could produce protective effects against induced demyelination through affecting immune responses.

Daryoush Shahbazi-Gahrouei, Mohsen Saeb, Shahram Monadi, Iraj Jabbari
Adv Biomed Res
2017, 6:117 (21 September 2017)
DOI
:10.4103/abr.abr_268_16
PMID
:28989910
Background:
Performing audits play an important role in quality assurance program in radiation oncology. Among different algorithms, TiGRT is one of the common application software for dose calculation. This study aimed to clinical implications of TiGRT algorithm to measure dose and compared to calculated dose delivered to the patients for a variety of cases, with and without the presence of inhomogeneities and beam modifiers.
Materials and Methods:
Nonhomogeneous phantom as quality dose verification phantom, Farmer ionization chambers, and PC-electrometer (Sun Nuclear, USA) as a reference class electrometer was employed throughout the audit in linear accelerators 6 and 18 MV energies (Siemens ONCOR Impression Plus, Germany). Seven test cases were performed using semi CIRS phantom.
Results:
In homogeneous regions and simple plans for both energies, there was a good agreement between measured and treatment planning system calculated dose. Their relative error was found to be between 0.8% and 3% which is acceptable for audit, but in nonhomogeneous organs, such as lung, a few errors were observed. In complex treatment plans, when wedge or shield in the way of energy is used, the error was in the accepted criteria. In complex beam plans, the difference between measured and calculated dose was found to be 2%–3%. All differences were obtained between 0.4% and 1%.
Conclusions:
A good consistency was observed for the same type of energy in the homogeneous and nonhomogeneous phantom for the three-dimensional conformal field with a wedge, shield, asymmetric using the TiGRT treatment planning software in studied center. The results revealed that the national status of TPS calculations and dose delivery for 3D conformal radiotherapy was globally within acceptable standards with no major causes for concern.

Bahman Rashidi, Mohammad Mardani, Mostafa Peyvandi Karizbodagh
Adv Biomed Res
2017, 6:116 (21 September 2017)
DOI
:10.4103/abr.abr_179_16
PMID
:28989909
Background:
Human endometrium is a dynamic tissue during the menstrual cycle can be influenced by ovarian hormones. The purpose of this study was to evaluate the endometrium angiogenesis under the influence of human menopausal gonadotropin and human chorionic gonadotropin (HMG and HCG) that stimulate ovulation and progesterone.
Materials and Methods:
In this study, thirty adult female mice were randomly divided into three groups as: control, gonadotropin and gonadotropin + progesterone. The mice in the other two groups except the control group received 7.5 IU HMG and later HCG. Subsequently, the mice were placed in a cage for mating. Gonadotropin + progesterone group was administered, 1 mg/mouse progesterone in 24, 48, and 72 h interval, after HMG injection. Ninety-six hours after HMG injection, animals were sacrificed, and their uterine specimens were prepared by immunohistochemistry technique for light microscopic studies, and statistical analysis was carried out.
Results:
Endometrium angiogenesis in control group showed that mean ± standard deviation was 24.15 ± 11.15, gonadotropin group was 62.50 ± 24.16, and gonadotropin + progesterone group was 41.85 ± 19.54. Significant difference between the control group and gonadotropin group and between the control group and gonadotropin + progesterone was observed. Statistically significant differences were observed in all groups in the endometrial angiogenesis (
P
< 0.05).
Conclusion:
Ovarian induction with gonadotropins and gonadotropins + progesterone could not change the morphometrically index of endometrial glandular epithelium in mice. Ovarian stimulation followed by progesterone injection could modify the angiogenesis of mice endometrium.

Adv Biomed Res
2017, 6:115 (21 September 2017)
DOI
:10.4103/abr.abr_151_16
PMID
:28989908
Background:
Hypotension is one of the most common complications after spinal anesthesia for cesarean delivery. Normally, preloading with fluids, especially crystalloids, is used to prevention of hypotension.
Methods:
In the present randomized clinical trial study, 120 parturients presenting for elective cesarean section with the American Society of Anesthesiologists Class I and II received either 15 cc normal saline or 7 cc/kg hydroxyethyl starch 6% (Voluven) fluid. Information regarding to systolic, diastolic, mean arterial pressure, and heart rate, incidence of hypotension, adverse effects, the total dose of atropine, and ephedrine were recorded in before and 3, 6, 9, 15, and 20 min after spinal anesthesia. Furthermore, Apgar score of newborn at the 1
st
and 5
th
min after birth was recorded.
Results:
There was no significant difference in mean arterial pressure at different stages such as: Exactly after spinal and 3, 6, 15, and 20 min after spinal anesthesia between two groups (
P
> 0.05). Total dose of ephedrine and atropine were similar between groups (
P
> 0.05), respectively. There was no significant difference in Apgar score at the 1
st
and 5
th
min after birth between two groups. There were not any adverse effects of drugs in two groups.
Conclusions:
The results of this study show that hydroxyethyl starch 6% compared to normal saline are similar to prevent hypotension during spinal anesthesia for cesarean delivery.
