Background: Metabolic syndrome (MetS) is a prevalent disorder in pediatric age groups, described by a combination of genetic and environmental factors. Sterol regulatory element-binding transcription factor 1 (SREBF-1) induces the expression of a family of genes involved in fatty acid synthesis. Moreover, dysregulation of miR-33b, which is located within the intron 17 of the SREBF-1 gene, disrupts fatty acid oxidation and insulin signaling, thus leading to MetS. The aim of the present study was to investigate the association between SREBF-1 rs8066560 polymorphism and MetS in Iranian children and adolescents. Methods: This study includes 100 MetS and 100 normal individuals aged 9-19 years. Anthropological and biochemical indexes were measured. The -1099G > A polymorphism was genotyped by TaqMan real-time polymerase chain reaction. Results: Significant differences were observed in anthropometric measurements and lipid profiles between MetS and normal children. There were no differences in the genotype frequencies or allele distribution for -1099G > A polymorphism between MetS and control groups. High-density lipoprotein cholesterol levels were significantly higher in the MetS GG group than in the A allele carrier group. The genotype AA controls had significantly increased cholesterol and low-density lipoprotein cholesterol levels than AG genotypes. By logistic regression using different genetic models, no significant association was observed between SREBF-1 rs8066560 polymorphism and the risk of MetS. Conclusions: We conclude that the -1099G > A variant on SREBF-1 gene associated with serum lipid profiles, however, it may not be a major risk factor for the MetS in Iranian children and adolescents.

Background: Vitamin C levels are low in pregnancy. The purpose of this study was to determine serum Vitamins C levels among pregnant women attending antenatal care at a General Hospital in Dawakin Kudu, Kano, and this can help further research to determine the place of Vitamin C supplementation in pregnancy. Methods: This was a prospective study of 400 pregnant women who presented for antenatal care in General Hospital Dawakin Kudu, Kano, Nigeria. Research structured questionnaire was administered to 400 respondents. Determination of serum Vitamin C was done using appropriate biochemical methods. Results: Vitamin C deficiency was found in 79.5% of the participants. The values for Vitamin C were 0.20 ± 0.18 mg/dl during the first trimester, 0.50 ± 0.99 mg/dl in the second trimester, and 0.35 ± 0.36 mg/dl in the third trimester and P = 0.001. Conclusions: There is a significant reduction in the serum Vitamins C concentration throughout the period of pregnancy with the highest levels in the second trimester. Therefore, Vitamin C supplementation is suggested during pregnancy, especially for those whose fruit and vegetable consumption is inadequate.

Background: Behavioral disorders are common in the pediatric age group. This study aims to assess the relationship between the frequency of behavioral and mental disorders and counseling with family members and friends in a representative sample of Iranian children and adolescents. Methods: In this nationwide study, 14880 school students, aged 6-18 years, were selected by cluster and stratified multi-stage sampling method from 30 provinces in Iran. The World Health Organization Global School-based Health Survey questionnaire was used. Results: Overall, 13486 students (49.2% girls) with the mean (standard deviation) age of 12.47 (3.36) years completed the study. According to the students' self-report, 56.1% of boys and 42.2% of girls shared their problems with their fathers. All behavioral disorders were less prevalent in children and adolescents who consulted with their father compared with those who did not (P < 0.001). In addition, 84.6% of boys and 84.0% of girls shared their problem with their mother. All behavioral disorders were less prevalent in children and adolescents who consulted with their mother compared with those who did not (P < 0.001). 45.6% of boys and 44.8% of girls shared their problem with their brother or sister. Some behavioral disorders were less prevalent in children and adolescents who consulted with their brother or sister (P < 0.01); however, the prevalence was not statistically different for most disorders (P > 0.05). Moreover, 60.4% of boys and 66.0% of girls shared their problems with their friends. The prevalence of most behavioral disorders was lower in those who consulted with their friends (P < 0.001). Conclusions: Children and adolescents should be encouraged to consult with their parents and friends about their problems. Parents should offer their children an opportunity to express their views and wishes about their problems.

Background: Diabetes mellitus (DM) is a public health challenge worldwide and to manage it the patient is required to make some fundamental changes in behavior. Patients should be involved in care program to improve their diabetes condition and quality of life (QOL). This study aimed to examine the effect of educational program on beliefs, behavior, glycemic control indicator, and QOL among diabetic women. Methods: In this interventional study, 90 female outpatients with type 2 diabetes were randomly selected from those referred to diabetes clinic in Khoy, Iran, during 2011. They were divided into two groups, 45 participants as the intervention group and 45 subjects as the comparison group. Knowledge, beliefs, and behavior by valid and reliable questionnaires, and health-related QOL (HRQOL) by means of WHOQOL-BREF questionnaire were assessed. Hemoglobin A1c level (HbA1c) was measured by the colorimetric method, educational program was conducted on the intervention group for 4 weeks, and changes were compared in two groups after a 3-month follow-up. Results: After intervention, there was a significant difference between two groups in terms of the mean scores of knowledge (P < 0.001), attitude (P < 0.01), self-efficacy (P < 0.001), and behavior (P < 0.001). The findings also indicated that there were significant differences between the groups in mean scores of physical, psychological, and social domains of QOL after intervention (P < 0.001). In addition, there was a statistically significant difference between two groups in the mean value of HbA1c after educational intervention (P < 0.01). Conclusions: Instructional interventions based on interactive approaches can be useful, and applicable for behavior modification and improvement of HbA1c level and HRQOL in people with DM.

Background: To test the change in the knowledge of the study participants following a Blended Training and Learning Approach (BTLA). Secondly, the paper also tries to discuss the use of this method over the classical classroom based trainings. Frontline health functionaries are the backbone of almost all health goals. It is therefore essential to ensure proper training of this cadre of workers for optimum service delivery. The present paper tries to discuss the use of an effective new training pedagogy over the classical classroom based trainings. Methods: A cross-sectional study was conducted from August 2013 to April 2014 in all districts in the state of Odisha. The study participants comprised of two groups. Group 1: Integrated Child Development Services supervisors, Child Development Project Officers received training on reduction of stunting. Group 2: Nutrition Counselors and Auxiliary Nurses and Midwifes received training on management of severe acute malnutrition (SAM). Selection of participants was done following complete enumeration technique. The training effectiveness was measured using paired t-test. Out of approximately 2400 participants identified across the state of Odisha, 2350 participants provided consent to participate in the study. Results: The change in knowledge was determined by using paired t-test. The results of the paired t-test for the training on reduction of stunting were significant, P < 0.001, indicates that there was a significant increase in the score from (mean = 11.4; standard deviation [SD] = 2.34) to the post-test (mean = 13.8; SD = 2.34). The mean increase was 2.4 with 95% confidence interval [CI] for the difference between means of 11.4 and 13.8. Similar test was conducted to evaluate the training on SAM. The results of the paired t-test were significant, P < 0.001, indicates that there was a significant increase in the score from (mean = 14.7; SD = 2.8) to the post-test (mean = 15.8; SD = 2.3). The mean increase was 1.12 with 95% CI for the difference between means of mean = 14.7 to mean = 15.8. There are different approaches that can be adapted during any training ranging from the traditional form of classroom teaching to the new technologically advanced forms of training such as e-learning. Understanding the merits and demerits, there was the felt need to try a newer approach of training. Thus, the method of BTLA was tried in the study and was proved to be effective. Conclusions: The newly tried and tested pedagogy of training would provide the necessary evidence for future policy decisions.

Background: Despite considerable investment in research, the existing research evidence is frequently not implemented and/or leads to useless or detrimental care in healthcare. The knowledge-practice gap proposed as one of the main causes of not achieving the treatment goals in diabetes. Iran also is facing a difference between the production and utilization of the knowledge of diabetes. The aim of this study was to assess the status of diabetes knowledge translation (KT) in Iran. Methods: This was a survey that executed in 2015 by concurrent mixed methods approach in a descriptive, cross-sectional method. The research population was 65 diabetes researchers from 14 diabetes research centers throughout Iran. The research was carried out via the self-assessment tool for research institutes (SATORI), a valid and reliable tool. Focus group discussions were used to complete this tool. The data were analyzed using quantitative (descriptive method by Excel software) and qualitative approaches (thematic analysis) based on SATORI-extracted seven themes. Results: The mean of scores "the question of research," "knowledge production," "knowledge transfer," "promoting the use of evidence," and all aspects altogether were 2.48, 2.80, 2.18, 2.06, and 2.39, respectively. The themes "research quality and timeliness" and "promoting and evaluating the use of evidence" received the lowest (1.91) and highest mean scores (2.94), respectively. Except for the theme "interaction with research users" with a relatively mediocre scores (2.63), the other areas had scores below the mean. Conclusions: The overall status of diabetes KT in Iran was lower than the ideal situation. There are many challenges that require great interventions at the organizational or macro level. To reinforce diabetes KT in Iran, it should hold a more leading and centralized function in the strategies of the country's diabetes research system.

Background: The prevalence of colorectal cancer (CRC) is rapidly increasing in Iran. It holds the most prevalent cancer after skin, breast, and gastric cancers among the Iranian population. The current study was designed to investigate the effects of leisure time, occupational and household physical activity as well as exercise on the risk of CRC in the Iranian population. Methods: In this population-based case-control study, 100 individuals with a recent diagnosis of CRC who were eligible for the study were recruited between 2006 and 2008. The control groups were selected from patients' companions (excluding first- and second-degree relatives) without past history of cancer or any physical disability. Physical activity of the participants was evaluated using a Kriska retrospective physical activity questionnaire. The relation between CRC and physical activity was assessed via logistic regression model and calculating the odds ratio (OR) as well as a confidence interval (CI) of 95%. Results: According to the findings, the adjusted OR of occupational (OR = 0.98, 95%, CI: 0.95-1.02) and house holding physical activities (OR = 1.03, 95% CI: 0.99-1.08) were not significantly different between the case and control groups for women (P > 0.05). The risk of CRC shows a significant reduction in individuals with moderate leisure physical activities compared to those with minimal activities (OR = 0.82, CI 95%: 0.73-0.98). Conclusions: The study suggests that the risk of CRC will decrease in individuals with higher leisure physical activities (especially with an increase in hours of brisk walking during the day).

Background: Esophageal cancer is the sixth cause of death in the world, there was a lack of population-based information on the trend and incidence rate of esophagus cancer, so this study aimed to determine the incidence and pathological changes of esophagus cancer in Iran. Methods: In this study, data were extracted from annual cancer registry reports of Iranian ministry of health between 2003 and 2008. Standardized incidence rates were calculated using the world standard population, and incidence rate was calculated by age groups, sex, and histological type. Data on epidemiologic trend and histology were analyzed using Joinpoint software package. Results: In this study, there were 18,177 recorded cases of esophagus cancer. Of all cases, 45.72% were females and 54.28% were males. Sex ratio was 1.19. The most common histological types related to squamous cell carcinoma NOS and adenocarcinoma NOS were 64.53% and 10.37%, respectively. The trend of annual changes of incidence rate significantly increased in both sexes. The annual percentage changes, the incidence rate was 7.9 (95% confidence interval [CI]: 3.3-12.6) for women and 9.6 (95% CI: 6.0-13.2) for men. The histology type of SCC, large cell, nonkeratinizing and SCC, keratinizing and SCC, NOS had a significant decreasing trend in total population (P < 0.05). Conclusions: According to this study, the trend of age-standardized incidence rate of esophagus cancer in Iran is rising. Hence, to prevent and control this cancer, it is necessary to investigate related risk factors and implement prevention programs in Iran.

Background: Control of blood sugar, hypertension, and dyslipidemia are key factors in diabetes management. Cucurbita ficifolia (pumpkin) is a vegetable which has been used traditionally as a remedy for diabetes in Iran. In addition, consumption of probiotics may have beneficial effects on people with Type 2 diabetes. The aim of this study was an investigation of the effects of C. ficifolia and probiotic yogurt consumption alone or at the same time on blood glucose and serum lipids in diabetic patients. Methods: Eighty eligible participants randomly were assigned to four groups: 1 - green C. ficifolia (100 g); 2 - probiotic yogurt (150 g); 3 - C. ficifolia plus probiotic yogurt (100 g C. ficifolia plus 150 g yogurt); and 4 -control (dietary advice) for 8 weeks. Blood pressure, glycemic response, lipid profile, and high-sensitive C-reactive protein (hsCRP) were measured before and after the intervention. Results: Total cholesterol (TC) decreased significantly in yogurt and yogurt plus C. ficifolia groups (within groups P = 0.010, and P < 0.001, respectively). C. ficifolia plus yogurt consumption resulted in a decrease in triglyceride (TG) and an increase in high-density lipoprotein cholesterol (HDL-C) (within groups P < 0.001 and P = 0.001, respectively). All interventions led to a significant decrease in blood sugar, hemoglobin A1c (HbA1c), hsCRP, and low-density lipoprotein cholesterol (LDL-C) level within groups. Blood pressure decreased significantly in Cucurbita group and yogurt group (within groups P < 0.001, and P = 0.001 for systolic blood pressure [SBP] and P < 0.001, and P = 0.004 for diastolic blood pressure [DBP], respectively). All variables changed between groups significantly except LDL-C level. Conclusions: Variables including TG, HDL-C, TC, fasting blood sugar, HbA1c, SBP, DBP, and hsCRP changed beneficially between groups. It seems that consumption of C. ficifolia and probiotic yogurt may help treatment of diabetic patients.

Background: Green tea is one of the most popular beverages in the world. It is believed to have beneficial effects in the prevention and treatment of many diseases, one of which is nonalcoholic fatty liver disease (NAFLD). The present study investigated the effects of consumption of green tea in NAFLD patients. Methods: This study was a double-blind, placebo-controlled, randomized clinical trial. Ultrasonography was used to diagnose fatty liver in patients with alanine aminotransferase (ALT) >31 mg/dl and 41 mg/dl and aspartate aminotransferase (AST) >31 mg/dl and 47 g/dl in women and men, respectively and without other hepatic diseases. A total of 80 participants (20-50 years) with NAFLD were randomly allocated into two groups to receive either green tea extract (GTE) supplement (500 mg GTE tablet per day) or placebo for 90 days. At baseline and at the end of the intervention weight, serum ALT, AST, and alkaline phosphatase (ALP) were measured in fasting state, and dietary data were collected at baseline and end of the study. Results: Green tea group showed significant reductions in ALT and AST levels after 12 weeks period (P < 0.001). The placebo group showed a reduction in ALT and AST levels at the end of the study, but it was no significant. ALP levels showed significant reductions in both groups after 12 weeks period (P < 0.001). Conclusions: According to the findings of this study, GTE supplementation decrease liver enzymes in patients with NAFLD. It can be claimed that GTE prescribed can be considered as a treatment to improve serum levels of liver enzymes in NAFLD patients.
