Abstract
Background: This study aims to evaluate the outcomes and late complications of open Roux-en-Y gastric bypass surgery in the treatment of morbid obesity. Methods: Over a 15 year-period between May 1997 and May 2012, we reviewed our experiments with 39 patients who underwent open gastric bypass for morbid obesity. The weight of the patient and surgical complications were recorded. Ideal weight, body mass index, weight loss and excess weight loss were calculated. Results: The follow up period ranged from 6 to 180 months with a mean of 100 months after operation. Average weight loss was 3.9 and 0.28 kg per month during the first and second years after operation weight loss was slower from the third year on-wards. Weight loss generally was stabilized between 12 and 18 months after operation. Only one patient (2.6%) had a weight loss failure criterion. Concomitant condition ex-isted in 14 patients (48.2%) of our series. These included hypertension in 3 cases (10.3%) that was resolved in 100%, diabetes mellitus in 4 (13.7%) that was resolved in 75%, cholelithiasis in 7 cases (24.1%) that was resolved by cholecystectomy during the operation. There was no early postoperative death. Early complications occurred in 2 patients (5.1%), including pulmonary embolism (2.6%) and gastrointestinal bleeding (2.6%). The late complications occurred in 7 patients (17.9%) involved 2 patients with anastomotic stricture at the gastrojejunostomy (5.1%), One patient with symptomatic cholelithiasis (2.6%), three patient with anemia (7.7%), and one patient had Wernicke ’s disease who died of this complication (2.6%). Conclusion: The results of the study showed that the open Roux-en-Y gastric bypass surgery is an effective procedure in the treatment of morbid obesity with minimal late complications.

Abstract
Background: Apelin is an adipokine which may contribute to the link between obesity and metabolic diseases. Regular exercise training has been proposed as a strategy for reducing the risk of these diseases by positive adaptations in adipokines, but there is limited research directly comparing different types of training. The purpose of this study was to determine and compare the effects of nonlinear resistance training (NRT) and aerobic interval training (AIT) on serum levels of apelin-13 and insulin resistance in middle-aged obese men. Methods: This quasi-experimental study was conducted from October to February 2012 in Ilam City, Iran. Eligible subjects (33 obese men) between aged 34-46 years participated in this study and were allocated to the following groups: NRT (n= 12), AIT (n= 10), and control (n= 11). The inclusion criteria were sedentary (less than 60 minutes physical activity per week), nonsmokers, no regular exercise for at least the past 6 months, no regular consumption of medication, no special diet, percentage body fat > 23% and no history of medical conditions that would prevent them from participating in the exercise intervention. Only the subjects who performed more than 90% of the training sessions were included in this study. The experimental groups performed 3 weekly sessions for 12 weeks, whereas the control group maintained a sedentary lifestyle. NRT consisted of 40-65 minutes of weight training at different intensities and with a flexible period. AIT consisted of running on a treadmill (4×4 min at 80-90% maximal heart rate, 3 min recovery intervals). Results: Analysis of variance showed that there were no significant differences betwee n the groups for apelin-13 and insulin resistance at baseline (P> 0.05). Compared to control group, two exercise programs were equally effective at reducing insulin resistance, but apelin-13 levels increased significantly only with the AIT (P= 0.04). After the training, maximal oxygen uptake increased significantly in AIT and NRT compared with control group (both P= 0.001) and in AIT more than NRT (P= 0.001). Conclusion: The practical applications indicate that obese men can use both AIT and NRT exercise programs to reduce insulin resistance. However, the AIT may have better beneficial effects (as indicated by apelin-13) compared to NRT.

Abstract
Background: Today obesity and overweightness are the major health problem all over the world. The relation between decreasing serum level of vitamin D and some chronic diseases such as diabetes and obesity was shown in the available studies. The aim of this study was to determine the prevalence of vitamin D deficiency among obese and overweight Iranian population and its relation with age, sex, occupation, body fat percentage and body weight according to body mass index. Methods: In a descriptive cross-sectional study, all patients who were referred to obesity clinic of Imam Khomeini Hospital, Tehran, for weight management throughout one year were included to the study. The prevalence of vitamin D deficiency with serum level lower than 30 ng/ml among 107 subjects was evaluated. The data were analyzed by SPSS, ver. 19 (SPSS, Inc., Chicago, IL, USA). Quantitative variables were presented as mean±SD and qualitative variables were presented as relative frequency. The groups were compared with independent samples t-test and Chi-square test. The level of significance for comparing the groups was considered at P<0.05. Results: In 107 participants, vitamin D deficiency in 81 subjects (75.7%) was reported. The prevalence of deficiency in participants with body mass index between 25 to 29.9, 30 to 34.9 and equal or greater than 35 kg/m2 was 77.3%, 83.7% and 69.4%, respectively. However, the differences between overweight and obese groups were not significant (P=0.193). The prevalence of moderate and severe vitamin D deficiencies among the participants was 50.5% and 25.2 %, respectively. Vitamin D deficiency was more common in participants below 50 years of age compared with those older than fifty (P=0.001). Conclusion: The prevalence of vitamin D deficiency was high in obese and overweight population especially among individuals younger than 50 years. It seems that, it is necessary to add prevention and management of this deficiency to obesity treatment protocols especially in the young adults.

Abstract
Background: Cancer and obesity are two major public health concerns. More than 12 million cases of cancer are reported annually. Many reports confirmed obesity as a risk factor for cancer. The molecular relationship between obesity and breast cancer has not been clear yet. The purpose of this study was to investigate priorities of effective genes in the molecular relationship between obesity and breast cancer. Methods: In this study, computer simulation method was used for prioritizing the genes that involved in the molecular links between obesity and breast cancer in laboratory of systems biology and bioinformatics (LBB), Tehran University, Tehran, Iran, from March to July 2014. In this study, ENDEAVOUR software was used for prioritizing the genes and integrating multiple data sources was used for data analysis. Training genes were selected from effective genes in obesity and/or breast cancer. Two groups of candidate genes were selected. The first group was included the existential genes in 5 common region chromosomes (between obesity and breast cancer) and the second group was included the results of genes microarray data analysis of research Creighton, et al (In 2012 on patients with breast cancer). The microarray data were analyzed with GER2 software (R online software on GEO website). Finally, both training and candidate genes were entered in ENDEAVOUR software package. Results: The candidate genes were prioritized to four style and five genes in ten of the first priorities were repeated twice. In other word, the outcome of prioritizing of 72 genes (Product of microarray data analysis) and genes of 5 common chromosome regions (Between obesity and breast cancer) showed, 5 genes (TNFRSF10B, F2, IGFALS, NTRK3 and HSP90B1) were the priorities in the molecular connection between obesity and breast cancer. Conclusion: There are some common genes between breast cancer and obesity. So, molecular relationship is confirmed. In this study the possible effect of gene F2 polymorphism in making breast cancer associated with obesity risk factor was confirmed, the fact that past studies have not been reported.

Abstract
Background: The major issue to address in obesity etiology is to identify the genetic changes in the disease and their occurrence in different populations. Uncovering these genetic changes may be important in developing potential biomarkers for early diagnosis and prognosis of obesity. Among all obesity susceptibility genes studied before, convincing association has been found with variants in the FABP2 gene and this disease; however, the contributions of these genetic variants in different populations and ethnic groups are not similar. Accordingly, this study was carried out to replicate the previous findings to assess whether a missense variation (rs1799883) in this gene is associated with obesity in the Tehran Lipid and Glucose Study (TLGS) population.
Methods: A case–control study was designed to determine the possible association between rs1799883 and occurrence of obesity “in phase IV of the study between the years of 2008 to 2011”. The study group consisted of 217 subjects with body mass index (BMI, kg/m2) greater than 30 as cases and 159 healthy individual as control group (18
Results: The results showed no significant differences between case and control groups in terms of allele frequency (P=0.61). According to the findings, the presence of T allele as the risk allele was not associated with increased risk of obesity in carriers of this allele compared to individuals carrying the normal allele (OR=1.17; CI%95= 0.62-2.19, P=0.61).
Conclusion: The results did not support the previous findings of an association between genetic polymorphism in the FABP2 gene and risk of obesity. However, a number of replicated studies with other ethnicity are suggested to make a conclusion about the role of this genetic polymorphisms and susceptibility to obesity in Iranian population.

Abstract
Background: Obesity is one of the most important problems in developed countries and cause cardiovascular diseases, diabetes and hypertension. The complex phenotype influenced by both genetic and the environment factors. One of the most important genes which is effective in this phenotype is peroxisome proliferator-activated receptor gamma (PPAR-γ). This study was carried out of investigate the association of Pro12Ala (rs1801282) polymorphism in mentioned gene with obesity in Tehran Lipid and Glucose Study (TLGS).
Methods: The present study done in September 2014 in Cellular and Molecular Endocrine Research Center, Research Institute for Endocrine Sciences, Shahid Beheshti University of Medical Sciences. For the present case-control study 239 subjects with excess weight and body mass index more than 30 kg/m2 as a case and 240 subjects with normal weight and body mass index less than 25 kg/m2 as a control were selected. The rs1801282 was proliferated, detected and genotyped using tetra-primer amplification refractory mutation system-polymerase chain reaction (ARMS-PCR) method.
Results: The results indicated that there was significant association between the presence of risk allele G of rs1801282 and obesity disease in the TLGS population (P=0.000). Genotype and allelic frequencies of rs1801282 in patient and healthy group were: 55.2% and 23.8% for GG, 24.3% and 30.4% for GC, 20.5% and 45.8% for CC, 67% and 39% for G, 33% and 61% for C, respectively.
Conclusion: The results of study indicated that the presence of G allele could be increase 1.7 the risk of obesity. These differences in patient and healthy group lead us to select this marker as a genetic marker to predict the risk of obesity. There are statistical differences between the distribution of mentioned polymorphism in Tehranian population and other populations. However, replicating the study in a larger population of Tehranian people with more affected cases is suggested to generalize the results of this study.

Abstract
Background: Hypertension is one of the most important chronic illness worldwide and one the major risk factors for cardiovascular diseases. Obesity and abdominal obesity are risk factors for high blood pressure. Population attributable fraction (PAF) answers the question of how much of the disease burden in a certain population may be reduced if a risk factor like obesity is removed from the population. It implies that reducing prevalence of obesity as a risk factor of hypertension, may reduce the burden of hypertension and its consequences. The aim of this study was to determine the population attributable fraction of hypertension associated with obesity, abdominal obesity and joint effect of them in the men of Mazandaran Province, North of Iran.
Methods: In this epidemiological study, the data of non-communicable disease surveillance system in 2009 has been achieved. Then measure of association between obesity and hypertension (Odds Ratio) was extracted from Tehran Lipid and Glucose Study (TLGS). After standardizing the data, the population attributable risk for men based on the above formula (Levin's attributable fraction formula) has been calculated.
|
Results: In our study based on population attributable fraction, results in blood pressure caused by obesity were 14.5 (CI 95%: 10.7-17.2), the effect of abdominal obesity was 7.4 (CI 95%: 2.04-11.3) and deductions attributable joint effect both obesity and abdominal obesity was 22.6 (CI 95%: 9.7-25.6) respectively. Conclusion: Given the high prevalence of hypertension and obesity in Mazandaran men and the impact of obesity on blood pressure is necessary to prevent the spread of the disease. It is recommended that health promotion programs focus on men with high blood pressure due to obesity could be performed. |

Abstract
Background: Paraoxonase-1 (PON1) is one of the most important enzymes for removal of the free radicals, and the main protective factor for lipoproteins against oxidative agents. The purpose of this study was to investigate the effects of eight weeks’ rope training on paraoxonase-1 enzyme, insulin resistance and lipid profiles in inactive overweight and obese girls.
Methods: This quasi-experimental study was conducted in Iranian Azarbaijan Shahid Madani University of Tabriz, from November 2016 to January 2017. In this study, 20 healthy overweight and obese in-active girls (20-25 Yr) volunteered and randomly assigned into exercise (n=10) and control (n=10) groups. Exercise protocol was rope training was 8 week for 4 day per week in 45 minute per day. Some anthropometric indexes of subjects were measured before and after exercise. A fasting blood sample was collected as pre-test and post-test, followed by 48 hours of physical inactivity to measure serum levels of PON1 enzyme, Insulin, lipid profiles and other blood variables. Analysis of the data was performed by paired and independent samples t-tests by using the SPSS software, version 20 (IBM, Armonk, NY, USA). The criterion of statistical significance was set as P<0.05.
Results: The paired samples t-test results showed that after exercise intervention, in exercise group, the values of all variables (except low-density lipoprotein) were significantly changed. Also, to compare with control group, the values of PON1 enzyme (P=0.024) and maximum oxygen consumption (P=0.006) significantly increased and insulin resistance index (P=0.028), triglyceride (P=0.046) and body fat percent (P=0.001) were significantly decreased (P<0.05).
Conclusion: The results of this study showed that performing rope training for 8 weeks induced positive changes in paraoxonase-1 enzyme, insulin resistance index, maximum oxygen consumption and some lipid and anthropometric indices in overweight and obese young girls. Therefore, according to these results, rope training, as an aerobic activity it can be useful for all people especially in overweight and obese to control blood fats, body composition and prevent diseases due to obesity such as cardiovascular disease.

Abstract
Background: Anemia is the most common nutritional disorder in the world in which iron deficiency is one of its main causes. The prevalence of obesity and risk of iron deficiency anemia in these individuals is increasing. The present study examined the association between iron deficiency, dietary intake and obesity and obesity-induced inflammation in female students.
Methods: This descriptive cross-sectional study was conducted in Ahvaz University of Medical Sciences, Ahvaz, Iran, from May to March of 2016. A total of 170 female students were selected by stratified random sampling. Being in the age of 18-35 years, having a regular menstrual cycle, not following a specific diet and not taking any medication or dietary supplements that could affect iron status were indicators of inclusion in the study. General information and physical activity questionnaire were completed and a semi-quantitative feed frequency questionnaire was used to obtain food intake information. Anthropometric indicators including weight, height, body mass index (BMI), waist circumference and body fat were measured. Obesity was evaluated with 3 different definitions. Biochemical indices such as iron, hemoglobin, hematocrit, transferrin, total iron binding capacity (TIBC), ferritin, and hs-CRP were also measured.
Results: The dietary intake of iron and some nutrients related to iron (including energy, protein, vitamin C and calcium) showed no significant difference in dietary intake between different groups of obesity definitions. Serum iron levels and hemoglobin concentration had a significant negative correlation with BMI and hs-CRP concentrations (P=0.026 and P=0.01 respectively). The relationship between transferrin levels and total iron binding capacity with the index of waist circumference was positive and significant (P=0.040, P=0.034, respectively). Also, there was a significant positive correlation between obesity and hs-CRP levels (P=0.014). There was no significant relationship between other evaluated factors with different degrees of obesity.
Conclusion: Chronic obesity and inflammation which could be caused by obesity, can contribute to iron deficiency, regardless of dietary iron intake.

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: Gestational diabetes mellitus (GDM) is one of the most common medical complications in pregnancy, which is associated with many serious consequences for mother and her fetus. Body mass index (BMI) in pregnant women is considered as one of most effective factor for the incidence of GDM. The aim of this study was to determine the relationship between BMI at pregnant women in the early months of pregnancy and the incidence of GDM.
Methods: In this retrospective cohort study, the case of six hundred fifty-nine pregnant women who referred to health centers in Kermanshah City from September 2010 to September 2012 by convenience sampling method were selected and investigated. This study was sponsored by Kermanshah University of Medical Sciences. Height and weight were measured for each woman at the beginning of pregnancy and maternal body mass index (BMI) was calculated based on height and weight measurements. Then the pregnant women were divided into four groups based on BMI: thin (BMI less than 18.9 kg/m2), normal (BMI between 19 kg/m2 and 24.9 kg/m2), overweight (BMI between 25 kg/m2 and 29.9 kg/m2) and obese (BMI more than 30 kg/m2). Those women who had diabetes at the beginning of pregnancy were excluded from the study. GDM was considered as fasting blood glucose ≥92 between 26-30 weeks of gestation.
Results: The mean±SD age of pregnant women was 27.7±5.85 year and the mean of BMI was 24.4±4.0 kg/m2. The GDM was shown in 30.7% of women. Association between BMI and GDM were statistically significant (P<0.001). The risk of GDM onset was 1.24 times, for each unit increased in BMI, (P<0.001). The risk of GDM was significantly higher in overweight [OR=2.97, CI (2.01-4.39)] and obese [OR=16.89, CI (8.46-33.70)] women. Being underweight increased the risk of GDM onset up to 1.19 times, but not significant.
Conclusion: There is a significant relationship between maternal BMI in pregnant women at the beginning of pregnancy with GDM onset. Increased BMI is correlated with an increase in the incidence of GDM.

Abstract
Background: Today, overweight and obesity are major health concerns in developed and developing countries. Meanwhile, the issue is particularly important in children due to its consequences in adulthood. This study aimed to investigate the frequency of overweight and obesity in preschool children in Kerman, Iran.
Methods: This cross-sectional survey was conducted from December to March of 2016 among 731 preschool children (5 to 6 years old) who were selected using convenience sampling. The nutritional status of children was assessed according to the World Health Organization (WHO) expert committee guideline and based on body mass index (BMI) curves for age for boys and girls. Data were analyzed by SPSS software, version 21 (SPSS Inc., Chicago, IL, USA). Chi-square test was used for data analysis, and the significance level was considered less than 0.05.
Results: In this study, 376 boys (51.5%) and 355 girls (48.5%) were investigated. The mean and standard deviation of the age of the participants was 68.7±4.2 months, 53% of these children were first children of the family and 30% of them were only children. The prevalence of overweight and obesity was 9.2% and 8.1% respectively. There was no significant relationship between overweight and obesity with gender, number of siblings and parents' education. There was a borderline difference in birth order (P=0.05) and the frequency of overweight and obesity in the firstborn children was more than other birth orders.
Conclusion: The prevalence of overweight and obesity was high in preschool children. Since these risk factors in children are predictors of chronic diseases during adulthood, we need to design and implement interventions to decrease the prevalence of overweight and obesity in children.

The prevalence of overweight and obesity was 9.2% and 8.1% respectively. There was no significant relationship between overweight and obesity with gender, number of siblings and parents' education. There was a borderline difference in birth order (P=0.05) and the frequency of overweight and obesity in the firstborn children was more than other birth orders.
Conclusion: The prevalence of overweight and obesity was high in preschool children. Since these risk factors in children are predictors of chronic diseases during adulthood, we need to design and implement interventions to decrease the prevalence of overweight and obesity in children.

Abstract
Asthma is an inflammatory and chronic disease that affects about 300 million people globally. The disease is more common in developed countries. The increase in the prevalence of asthma is not only due to genetic factors, but also to many environmental factors related to urbanization and type of nutrition. It has been reported that obesity is an independent risk factor for asthma and obese children are at higher risk of asthma. The researchers found that many of the common phenotypes of obesity and asthma are due to genetic effects and some genetic component is common to asthma and obesity. Genetic data suggest that there are areas of genetic overlap between the obesity and asthma genes. These children experience more severe asthma and have a poor treatment outcome. On the other hand, there is an association between vitamin D deficiency in the earlier stages of life and incidence of asthma in the following years. Interestingly, obesity is a common risk factor for both asthma and vitamin D deficiency. Therefore, study on the interaction of asthma, obesity, and vitamin D deficiency may play an important role in unraveling the intricate nature of asthma. Prevalence of Pediatric asthma in 6-7 and 13-14 years-old children has been reported more than 10% in Iran. In this review we aimed to assess the latest findings about pediatric asthma and its association with obesity and vitamin D in Iran and the other countries. In addition, the results of a pilot study that has examined the frequency of overweight and obesity, as well as vitamin D deficiency in children with asthma in Tehran, are briefly presented. Enrolling a national study on obesity and vitamin D levels in children with asthma, can provide excellent information on the effects of obesity and vitamin D deficiency on asthma in Iranian children. Also the results could provide a basis for ecological studies to measure correlation between pediatric asthma and Sunlight and food and cultural habits in different parts of the country. Also, it is recommended that for a better understanding of the subject, experimental studies examine the effect of vitamin D supplementation and vitamin D-rich diets on the prevention and treatment of pediatric asthma in different age groups as well as different ethnicities of Iran.

Abstract
Background: Obesity is associated with chronic inflammation in obese subjects, which leads to an increase of inflammatory cytokines. This study aimed to evaluate the effect of different intensity circuit resistance training on levels of interleukin 1 beta and interleukin-10 in obese men.
Methods: In a semi-experimental trial during May to August 2020, 44 obese men from Tehran city were selected and randomly divided into 4 groups including 1) control (n=11), 2) low-intensity circuit resistance training (n=11), 3) Moderate intensity circuit resistance training (n=11) and 4) High-intensity circuit resistance training (n=11). Resistance training was performed in different intensities including1) High-intensity circuit resistance training: three sets of 10 repetitions with 80% 1RM 2) Moderate intensity circuit resistance: three sets of 13 repetitions with 60% 1RM and 3) low-intensity circuit resistance training: three sets of 20 repetitions with 40% 1RM, three sessions per week for 12 weeks. Also, the control group had their daily life during the 12-week research period and were prohibited from participating in regular exercise. Serum interleukin-1 beta (IL-1β) and interleukin-10 (IL-10) levels were measured using an ELISA kit. Data were analyzed with covariance analysis at P<0.05.
Results: Twelve weeks of low, Moderate and high intensity circuit resistance training significantly decreased IL-1β levels (P=0.001) and increased IL-10 levels in obese men (P=0.001). The decrease of IL-1β was significant in the high-intensity training group compared to low intensity (P=0.009) and moderate-intensity training groups (P=0.046). Also, the increase in IL-10 levels was significant in the high-intensity training group compared to the low-intensity (P=0.002) and the moderate intensity training group compared to the low intensity training group (P=0.004).

Abstract
Background: The vertical gastric plication technique leads to poor long-term outcomes and is associated with intolerable reflux, dysphagia, or weight gain in a high percentage of patients. Therefore, in this study, the therapeutic results of two methods with and without plication of the distal part of the stomach in gastric bypass surgery in patients with morbid obesity were compared.
Methods: In this clinical trial randomized single-blind study, 40 patients with morbid obesity who were referred to one of the hospitals affiliated with Jundishapur University of Medical Sciences in Ahvaz during March 2020-February 2021, were randomly divided into two groups: with plication of the distal part of the stomach (n=20) and without plication of the distal part of the stomach (n=20) in Roux-en-Y gastric bypass surgery. Weight loss rate, complications related to surgery, outcomes and satisfaction of patient were noted and followed up for one year.
Results: The mean percentage of weight loss at different times did not show a significant difference between the two groups (p>0.05). The length of hospitalization after surgery was significantly less in the distal gastric plication group (p=0.0001). During one year of follow-up, hypertension, diabetes, HLP, and reflux were well in the distal plication method but showed no significant difference (p>0.05). Satisfaction of the patients was more in the distal plication method and showed no significant difference (p>0.05). One year after the operation, the change of diet showed no significant difference in the two groups (p>0.05).
Conclusion: It looks that using the laparoscopic distal gastric plication method is an effective and safe method and is associated with early ideal weight loss, reduction of complications, and increase in satisfaction of patients with BMI>=35 kg/m2. No need to use a foreign body, stapler or bandage and the possibility of re-operation are the advantages of this technique.

Abstract
Background: Obesity and overweight are one of the components of metabolic syndrome and the cause of cardiovascular disease and sudden cardiac death. Obesity is associated with a wide range of electrocardiogram (ECG) abnormalities.
Methods: This case-control study was performed on 50 children and adolescents aged 9 to 18 years in Birjand from May to October 2020. In the control group, 25 people with normal weight and in the case group, 25 people with obesity or overweight were included in the study. Individuals with a body mass index of 85-95 percent were defined as overweight, ones with a body mass index above the 95th percentile were defined as obese, and individuals with a body mass index below the 85th percentile were defined as normal. After clinical examination, height, weight and electrocardiogram indices were measured and compared by using statistical tests by SPSS (Version 19) software.

Results: There were 15 boys in the control group and 17 boys in the case group. The mean age of the control and case groups was 11.28±2.13 and 10.96±1.97 years, respectively. The mean distance between the peak to the end of the T wave in the case group was 323.72±120.15 and in the control group was 79.20±13.06. The mean difference between the shortest and longest distance of TP-e in case group was 48±23.04 and in control group was 18.44±5.58, respectively. There was a statistically significant difference between the two indices (P<0.001). But in other variables, no statistically significant difference was observed between the two groups.

Conclusion: The results of the present study showed that obesity can have adverse effects on the ECG of children compared to normal-weight individuals. These changes are associated with an increased risk of arrhythmias. Given that these changes can be corrected with weight control, it is recommended to warn families and educate them to prevent and control overweight and obesity.

Abstract
Background: Exercise programs can lead to different physiological adaptations, but the effects of low-volume, low-frequency HIIT protocols with varying interval structures have not been thoroughly investigated. This study aimed to explore the impact of HIIT with high compression (HC) and low compression (LC), with or without berberine (BBR) supplementation, on hematological parameters in pre-diabetic men.
Methods: This semi-experimental study was conducted between October and December 2021 at Mazandaran University. Fifty-four overweight/obese men with a mean age of 48.6±6.6 years, a body mass index of 30.7±7.3 kg/m², and a body fat percentage of 34.4±4.3% were randomly and equally divided into one of six groups: HC, LC, HC+BBR, LC+BBR, BBR, and control. The HC group (2:1 work-to-rest ratio) and LC group (1:1 work-to-rest ratio) underwent training programs comprising 2-4 sets of 8 exercises at an intensity of 80-95% of their maximum heart rate twice a week for 8 weeks. Hematological responses to Bruce's incremental exercise test were measured before and after the intervention. Data were analyzed using a two-way ANOVA with Bonferroni's post hoc test, with a significance level set at P<0.05.

Results: Baseline hematological indices showed no significant differences between pre-diabetic and non-diabetic groups (all, P>0.05). Following the 8-week intervention, there were significant decreases in white blood cells (WBCs) in the LC and LC+BBR groups, and in lymphocytes across all intervention groups except BBR (all, P<0.05). Additionally, hemoglobin and hematocrit levels showed significant reductions in the HC and HC+BBR groups (both, P<0.05). However, in response to Bruce's incremental exercise test, a significant decrease in WBCs was observed in the LC and LC+BBR groups, with reductions of 18% and 25%, respectively (both, P<0.05).
Conclusion: The LC protocol, even without berberine supplementation, seems to provide better immunological benefits and result in less hemolysis compared to the HC protocol, as evidenced by reductions in white blood cell counts. |

Abstract
Managing overweight and obesity is associated with lower risks of chronic diseases like diabetes. Digital health, particularly smartphones or m-health, effectively manages body weight. Technologies such as telemedicine services, mobile health (mHealth) or the use of mobile phones or portable digital devices in healthcare services and wearable devices can be used in this field. Therefore, this study was conducted to understand the impact of digital health technologies on weight management in diabetic patients.
Methods: The present study is a systematic review study that was initially searched using a systematic review of published studies in the field of digital health for weight management in diabetic patients from October 1401 to October 1402. Our study was conducted in two rigorous steps. Firstly, we performed a systematic review by searching for publications on Digital Health Solutions for Body Weight Management in Diabetic Patients until 12 October 2022. We meticulously combed through two comprehensive databases, PubMed and Web of Science, using a set of specific and relevant keywords. After a thorough screening and full-text assessment, we handpicked eight documents for this study. We cross-referenced with the companies' websites producing the identified applications to enrich our findings further.

Abstract
Background: Gallstones are a common gastrointestinal complication following bariatric surgery, potentially resulting in cholecystitis, cholangitis, and pancreatitis. These complications arise due to biliary homeostasis alterations and rapid postoperative weight loss. Ursodeoxycholic acid (UDCA) has been shown to reduce biliary cholesterol saturation, thereby preventing gallstone formation. This study aimed to evaluate the effectiveness of Ursobil (UDCA) in preventing gallstones in patients undergoing bariatric surgery.
Methods: This case-control study was conducted study was conducted at Golestan Hospital in Ahvaz, Iran, from October 2022 to March 2023. Ethical approval was obtained from the institutional review board. Patients aged 18 to 65 years with a BMI between 35 and 65 kg/m² were eligible. Exclusion criteria included a history of gallstones, previous bariatric or cholecystectomy surgery, inflammatory bowel disease, recent UDCA use, or bleeding disorders. Participants were divided into two groups: the case group received 600 mg of UDCA daily for six months postoperatively, while the control group received no UDCA. Abdominal ultrasonography was performed before surgery and six months afterward. Outcome measures included gallstone formation, weight loss, need for cholecystectomy, and health-related quality of life, assessed using the WHOQOL-BREF questionnaire.
Results: The two groups were comparable in terms of age, gender distribution, and baseline BMI. The mean weight loss was similar between groups after six months. Gallstone formation occurred in 1.7% (n=1) of the UDCA group compared to 15% (n=9) of the control group (P=0.012). None of the patients in the intervention group required cholecystectomy, whereas 11.7% (n=7) in the control group underwent the procedure (P=0.011). Quality of life scores were higher in the UDCA group, though not statistically significant.
Conclusion: Oral administration of UDCA effectively and significantly reduces the risk of gallstone formation and the need for cholecystectomy in post-bariatric surgery patients. Routine use of UDCA during rapid weight loss phases may improve clinical outcomes and reduce gallstone-related complications. Preventive use of UDCA may effectively and significantly reduce gallstone-related morbidity in patients undergoing rapid weight loss.

Abstract
Background: Dumping syndrome is a common complication after bariatric surgery and can adversely affect patients’ quality of life, particularly in those with diabetes. Although gastric bypass has traditionally been associated with a higher risk of dumping syndrome, evidence comparing its frequency with sleeve gastrectomy remains inconclusive. This study aimed to compare the frequency of dumping syndrome following these two procedures in patients with morbid obesity.
Methods: This prospective cohort study was conducted from April 2021 to July 2022 at Sina Hospital in Tehran. A total of 90 patients with morbid obesity who met the indications for bariatric surgery were not randomly assigned to two treatment groups: gastric bypass (n = 45) and sleeve gastrectomy (n = 45). Baseline assessments included medical history, physical examination, review of medical records, and necessary specialist consultations (including endocrinology and cardiology). All patients’ data were recorded in the Sina Bariatric Surgery Registry Database. Following surgery, patients received standard postoperative care and were evaluated for symptoms of dumping syndrome at one and three months postoperatively using the validated Sigstad questionnaire. Statistical analyses were performed using SPSS software.
Results: The results showed no statistically significant differences between the two groups in terms of age group, gender, excess weight, preoperative BMI, final BMI, and history of diabetes prior to surgery (P-value > 0.05). The final weight was significantly higher in the sleeve gastrectomy group (P-value = 0.033). There were no significant differences in the frequency of early and late dumping syndrome related to the consumption of sweets and other foods between the two groups at the first and third postoperative months (P-value > 0.05). Early dumping syndrome following the consumption of sweets and bread was significantly more frequent among diabetic patients (P-value = 0.037 and P-value = 0.045, respectively).
Conclusion: The prevalence of dumping syndrome was similar in both sleeve and bypass groups. Weight loss over time was significant (P < 0.001) and did not differ between groups (P = 0.211). The syndrome was significantly more common in diabetic patients, highlighting the importance of careful postoperative care and dietary guidance.
