Abstract
Background: The aim of the study is to evaluate correlation between hyperhomocysteinemia and oxidative stress with severity of atherosclerosis lesions.
Materials and Methods: The patients (52 males and 36 females) were selected from individuals with angiographically defined CAD admitted to the shahid Madani Hospital. Control groups were selected from sex and age matched apparently healthy individuals (15 Males and 24 Females). Serum Homocysteine levles were measured by ELISA method (Awareness stat fax-2100 Model). Total antionxidant capacity of samples was determined by Autoanalyzer (COBAS MIRA plus model) using Randox kits. The correlation between the measured parameters and extension of atherosclerotic lesions were calculated using statistical analysis in the both groups.
Results: The mean levels of Homocysteine in patients and control groups were 20.38 ± 10.22 μmol/l and 18.56 ± 9.47 μmol/L respectively and the differences were not significant (p> 0.05) . In the patient group the mean level of Antioxidant capacity was 1.34 ± 0.12 mmol/L. whereas that of control was 1.39 ± 0.12 mmol/L (p>0.05). Using statistical analysis no correlation was noticed between extension of atherosclerosis lesions٫ low total antioxidant capacity and high serum total homocysteine .
Conclusion: In this study no significant differences between levels of homocysteine and total antioxidant in patients and control groups and no marked relationship between studied parameters suggest, that hyperhomocysteinemia has no important role in progress of atherosclerosis lesions.

Abstract
Background: A correlation between coronary artery disease (CAD) and atherosclerosis of peripheral arteries and the determination of noninvasive indexes for its existence and extent have been sought by many researchers. Some studies report that the intima-media thickness (IMT) of peripheral arteries could play this role. This study evaluated the correlation between the IMTs of common carotid and common femoral arteries and the degree of atherosclerosis in aortic arch and to evaluate the severity of CAD in candidates of coronary artery bypass grafting (CABG).
Methods: In a cross-sectional analytic-descriptive study, The severity of CAD, the grade of atherosclerosis of the aortic arch, and the IMTs of the common carotid and common femoral arteries were determined.
Results: There was a significant weak positive correlation between the IMT of common carotid artery (ρ = 0.193, p = 0.039) and common femoral artery (ρ = 0.206, p = 0.028) with the number of involved carotid vessels the mean of these two parameters was not significantly different between the three CAD groups. There was not any significant relation between the IMTs of common carotid and common femoral arteries with the severity of atherosclerosis in the aortic arch too. There was not any significant relation between the presences of atherosclerotic plaque in the common carotid or the common femoral arteries with the severity of CAD. The severe atherosclerosis of the aortic arch was significantly higher in patients with three vessel disease.
Conclusion: According to our results, the IMTs of common carotid and/or common femoral arteries may increase with the severity of CAD however, these parameters are not a surrogate for predicting the CAD severity.

Abstract
Background: Disruption of lipid metabolism threatens human life in all countries with different percentages and causes cardiovascular disease. Reducing physical activity and eliminating some of the food medications have exacerbated these complications. The aim of this study was to investigate the effect of ginger supplementation on the lipid profile and body composition of obese women following Pilates exercises.
Methods: This semi-experimental study was carried out at the Medicinal Plants Research Center of Ilam University of Medical Sciences, Iran, from September to December 2012. In this study, 90 pregnant women with type 2 diabetes mellitus were randomly divided into three groups: complement, placebo and control (30 objects in each group). The exercise protocol includes a ten-week Pilates exercise. The supplement group consumed 2 grams of ginger powder daily for ten weeks. The placebo group used starch (placebo) capsules for these ten weeks. The control group did not take any supplement and did not have any activity at all. Blood samples were taken prior to physical activity and 48 hours after the end of 10 weeks Pilates training three sessions per week (30 sessions). In order to investigate intra-group changes, t-test and one-way ANOVA were used to compare the groups.
Results: The results showed that after 10 weeks of using zinc supplements following Pilates exercise training in pretest and posttest, increases in HDL levels and decreased TG, LDL, Tcol, body composition and body weight in obese women. Also, consumption of 10 weeks of ginger supplement after aerobic exercise training on TG (P=0.001), LDL (P=0.02), Tcol (P=0.05) and HDL (P=0.01) in obese women in supplement and placebo groups had a significant impact.
Conclusion: The results of this study showed that Pilates exercises with daily consumption of 2 grams of ginger supplement for 10 weeks caused a significant decrease in lipid profiles, body fat percentage, weight, and hip circumference.

Abstract
Background: Helicobacter pylori infection and respiratory tract infection at the same time cause pathogenicity increase and death. The aim of this study was to evaluate the co-occurrence of upper respiratory tract disorders and gastrointestinal infections of H. pylori.
Methods: The present study was conducted as a systematic review and meta-analysis, from August 2019 to Agusut 2020, at Qazvin University of Medical Sciences. Articles in the international databases (April 2001-December 2018) on the coexistence of upper respiratory tract disorders with H. pylori gastrointestinal infections were examined. The random effect model with a 95% confidence level was used to analyze the data.
Results: The highest prevalence of respiratory disorders co-occurrence associated with adenoid tissue (33%), nasal polyps (100%), chronic rhinosinusitis (71%) and gastrointestinal infections of H. pylori was reported in 2006 in Turkey, 2011 in Poland and 2015 in Egypt. Concurrent prevalence of the disease, according to the type of upper respiratory tract disorders in all studies, the estimated effect size according to the random model was 53% in chronic rhinosinusitis, 63% in nasal polyps, 62% in adenoid tissue and 60% in total, which was significant (P=0/000). The prevalence of co-occurrence of upper respiratory tract disorders with gastrointestinal infections of H. pylori in patients was estimated to be 61% at the age of more than 27 years and 60% at the age of fewer than 27 years. Pooled estimation of the concurrent prevalence of infection (in total) was estimated to be 60% and was significant among the studies (P=0/000).
|
Conclusion: The concurrent prevalence of upper respiratory tract disorders with gastrointestinal infections of H. pylori was observed to be almost equal and significant in elderly and young patients. Due to the fact that the simultaneous occurrence of two types of infections and diseases in people is very dangerous, screening of patients with each of these infections is necessary to identify the other infection and prescribe appropriate drugs.

Abstract
Background: Correct clinical decision-making has a significant impact on the treatment process, achieving the expected clinical outcome and increasing patient satisfaction, and identifying the factors affecting it is essential for evidence-based medical education. This study aimed to determine the relationship between evidence-based medicine with academic self-efficacy and research self-efficacy of medical students.
Methods: This descriptive analytical study conducted from October 2022 to October 2023 on 45 medical students at Abadan University of Medical Sciences. After obtaining consent from the students and registering demographic and educational information, data collection was performed using evidence-based medicine, academic self-efficacy, and research self-efficacy questionnaires. Then data analyzed by descriptive statistics, Pearson correlation coefficient, Spearman correlation coefficient, and regression model in SPSS.
|
Results: The findings of our study showed that research self-efficacy in students who had research experience (189.03) was significantly higher than students who did not have research experience (140.76). In addition, the average score of academic and research self-efficacy and evidence-based medicine in students who had a history of membership in the student research committee was significantly higher than students who did not have a history of membership. Finally, it was found that evidence-based medicine had a direct and significant relationship with research self-efficacy (r=0.361, P<0.05) and academic self-efficacy (r=0.457, P<0.001). In examining the relationship between academic self-efficacy and research self-efficacy, it was also found that these two variables have a direct and significant relationship with each other (r=0.714, P<0.001). As well as, there was no significant relationship between academic self-efficacy, research self-efficacy, and understanding the characteristics of evidence-based practice with any of the variables of age, gender and entry year (P>0.05).
Conclusion: According to the obtained results, it can be concluded that academic self-efficacy and research self-efficacy have an effect on evidence-based medicine, and all of the above can be improved by teaching medical students to participate in student research committees and doing research work. In this way, it improves the quality of treatment in doctors.
