- چکیده انگلیسی: Abstract
Overweight and obesity has increased in prevalence over the last two decades in many developed and developing countries including Iran. The aim of this present study was to compare the weight reduction effects of ketogenic and low calorie diets on overweight and obese Iranian children. Seventy-six overweight or obese children aged 9-16 years recruited from outpatient Ghaem Hospital, Nutritional Clinic, were randomized into two groups: a low calorie diet (n=38), a ketogenic diet (n=38). Both groups were treated for three months and followed up weekly. Fasting lipid profiles, blood sugar, uric acid, high-sensitivity C-reactive protein, , and weight were measured. Body fat percentages were measured using Bioimpedance Analysis (Tanita body composition analyzer, BC-418, Japan) for all subjects’ in each visit. Both ketogenic and low caloric diets reduced obesity indices including body fat percentage and improved lipid profiles (P<0.05). Changes in body weight and BMI did not differ significantly between two groups (P>0.05). However, low caloric diet had more potential beneficial effect on body fat percentage and lipid profile than ketogenic diet (P<0.05).Results showed ketogenic diet did not have any remarkable effect on weight loss versus low caloric diet and it seems that both diets had similar effect on weight loss in overweight and obese children. This study revealed the low caloric diet had more potential beneficial effect on body fat percentage and lipid profile than ketogenic diet.- انتشار مقاله: 03-05-1397

- چکیده انگلیسی: Introduction: Non-alcoholic fatty liver disease (NAFLD) is a clinical pathologic condition, which leads to inflammation events in hepatocytes. The objective of present study was to compare the plasma levels of VEGF and sVEGFR-1 as inflammation factors in overweight and obese children and adolescents with and without NAFLD. Materials and Methods: A total sample of 70 overweight and obese children and adolescents (37 boys and 33 girls) were recruited from those admitted to a nutrition clinic in Mashhad, northeastern Iran. The presence of NAFLD was determined by FibroScan, ultrasound and elevation of liver enzyme. Plasma VEGF and sVEGFR1 were also determined for each individual. Results: VEGF levels (log transformed) showed a significant stepwise increase from “zero” to “first”, “second” and “third” grades (P trend<0.001). However, sVEGFR1 (log transformed) did not show a regular trend between different grades of NAFLD (P trend=0.3). The odds ratios (95% confidence interval) for VEGF across categories of NAFLD were 1.00, 0.99 (0.97-1.01), 1.02 (0.99-1.04), and 1.04 (1.02-1.06). The odds ratios remained relatively unchanged even after adjusting for sex, age and BMI. Conclusion: This study showed a significant positive association between plasma VEGF levels and grades of steatosis in overweight and obese children and adolescents, even after adjustment for age, sex and BMI.

- چکیده انگلیسی: Introduction: The present study aimed to evaluate the effects of hospitalization on the nutritional status and prooxidant-antioxidant balance (PAB) of the patients with myocardial infarction (MI).Methods: This study was conducted on 57 patients diagnosed with MI with the mean age of 58.44±12.80 years. The patients were admitted to the cardiac care unit (CCU) of Ghaem Hospital in Mashhad, Iran. Nutritional status of the patients was assessed using the nutritional risk screening (NRS-2002) questionnaire. In addition, anthropometric and biochemical parameters and their changes were evaluated. PAB was also assessed as an oxidative stress marker. In total, 15 patients stayed in the hospital for more than one week. The measurements were performed upon admission and discharge.Results: Upon admission, 49.1% of the patients were well-nourished, and 50.9% were at nutritional risk. As expected, the patients were overweight (36.8%) or obese (19.2%), and all the measures of adiposity were high. Well-nourished patients had lower serum PAB comparatively, while the difference was not statistically significant. The prevalence of the suboptimal nutrition index increased from 46.7% upon admission to 53.3% upon discharge. However, the increase was not considered significant due to the small sample size. Serum PAB increased within one week after admission, while the change was not significant (P=0.249).Conclusion: According to the results, the prevalence of suboptimal nutrition was high in the MI patients in Iran and increases during hospitalization.

- چکیده انگلیسی: Introduction: Thirst is one of the main complaints during Islamic fasting. As bread is the staple food among most Muslims, evaluating its impact on thirst is important. In this study, we investigated the effect of licorice-enriched barley bread compared to barley bread and white wheat bread. Methods: This clinical trial was performed on three consecutive days during Itikaf ceremony. Data were garnered by using a checklist including items on demographic data, weight, height, waist circumference, blood pressure, and pulse rate. Blood pressure and pulse rate measurements were repeated at the end of the study. The participants were divided into three groups receiving functional barley bread enriched with licorice, barley bread, and white wheat bread. The thirst sensation was assessed by Fan visual analogue scale. Also, 24-hour dietary recall was obtained on all the three days. Results: Overall, 273 people participated in this study. Thirst sensation in the functional barley bread was lower than that in the wheat bread and barley bread groups, but there were no significant differences between wheat and barley bread groups in this regard. During the fasting period, the greatest increase in thirst was observed during the first five hours of fasting in all the three groups, which was significantly lower in the functional barley bread group than the wheat and barley bread groups; however, there was no significant difference between wheat and barley bread groups in this respect. Finally, similar results were attained following fluid intake adjustment.Conclusion: This study showed that licorice enrichment of barley bread might alleviate thirst sensation among fasting individuals.

- چکیده:
- چکیده انگلیسی: Type I diabetes mellitus is a common chronic disease in adolescents. According to statistics, 12,243 diabetic Muslims fast in thirteen Islamic countries, 43% of whom have type I diabetes. This longitudinal study was conducted on volunteer adolescents with type I diabetes aged 13-18 years for 15 days using the census method. Three days before Ramadan and during the last three days of the study period, changes in the insulin dose, HbA1C, lipid profile, and body mass index (BMI) were evaluated. Among 10 volunteer patients, eight individuals could complete Ramadan fasting. Blood glucose analysis indicated a significant difference between the reported blood glucose levels (P<0.001). The highest blood glucose level was reported by the patients at 12 PM (mean: 204.33 mg/dL), and the lowest blood glucose level was reported before Iftar (mean: 120.43 mg/dL). No significant difference was observed in the levels of low-density lipoprotein (LDL), high-density lipoprotein (HDL), cholesterol, HbA1C, and triglyceride (TG) before and after fasting, and the only significant difference was denoted in the BMI of the patients (P=0.002). According to the results, fasting could be a safe, feasible option for the adolescents with type I diabetes under specific circumstances, such as the provision of intensive training before Ramadan, raising their awareness, and supervision of patients by specialist. Our findings demonstrated that with the exception of BMI, fasting had no effects on other biochemical parameters.

- چکیده انگلیسی: Introduction: In the holy month of Ramadan, Muslims abstain from eating and drinking during daytime and mostly take two meals per day. One of these major meals is consumed before sunrise (Sahur), and the other is taken after sunset (Iftar). The partial nutritional deprivation in Ramadan may affect the immune system, while the other rituals of this month might render fasting individuals susceptible to various pathological conditions, such as food-borne infections. The present study aimed to evaluate the risk factors of food-borne bacterial diseases in Ramadan. Methods: A comprehensive search was performed via databases such as Google Scholar and PubMed to identify the titles and abstracts of the relevant articles using specific terms regarding food safety issues, Ramadan, and fasting. Results: The major risk factors associated with the occurrence of food-borne diseases during Ramadan were inappropriate storage and handling of cooked food products, in-advance preparation of meals, and nutritional deficiency. Conclusion: According to the results, prevention of food-borne infections during Ramadan requires critical measures, such as the provision of high-quality food ingredients, improving personal hygiene, and cooking and storing of food products at proper temperatures.

- چکیده انگلیسی: Introduction: The present study aimed to assess the effects of Ramadan fasting on micronutrients and their correlations with ocular biometry. Methods: This prospective study was conducted on 89 healthy volunteers (51 males and 38 females) with the mean of 34.98±9.10 years in Mashhad, Iran. Participants received complete ophthalmic and systemic examinations one week before and one week after the holy month of Ramadan in 2015. Subjects with no history of systemic and ophthalmic diseases were enrolled in the study. Blood samples were obtained from all the participants in the morning in both phases of the study. Levels of micronutrients were measured in the blood samples using the Hitachi 717 analyzer (Hitachi, Japan). In addition, IOLMaster (Carl Zeiss Meditec AG, Germany) was applied to determine the ocular axial length (AL) and anterior chamber depth (ACD). Results: No significant differences were observed in the AL and ACD of the subjects before and after Ramadan fasting (P>0.05). Fasting was found to decrease the levels of uric acid, selenium, sodium, and potassium (P<0.05). However, serum phosphor was observed to increase after the fasting period (P=0.032). No changes were reported in the concentrations of the other micronutrients, including urea, calcium, iron, zinc, creatinine, and albumin (P>0.05). Moreover, no significant association was observed between the AL and ACD with the concentrations of the micronutrients during Ramadan (P>0.05). Conclusion: According to the results, fasting had no significant effects on the overall health and ocular biometry of the fasting individuals during Ramadan. Therefore, it seems that Ramadan fasting is a safe for healthy adults.

- چکیده انگلیسی: Introduction: Fasting during the month of Ramadan is obligatory for healthy Muslims after the age of puberty. This paper was aimed to compare the changes in hematological and biochemical parameters before and after Ramadan.
Methods:This prospective study was performed one week before and one week after the month of Ramadan in 2015. Eighty-nine subjects (51males and 38 females) with a mean age of 34.52±9.05 were enrolled in this study. Patients with systemic disorder, special drug using, and/or a history of previous surgery were excluded. Blood samples were taken from all participants before and after Ramadan to evaluate the effects of fasting on hematological-biochemical factors. Hematological and biochemical measurements were performed on the blood samples using a KX-21N cell counter (Kobe, Japan) and Hitachi 717 analyzer (Roche, Japan), respectively.
Results:Hematocrit, red blood cell (RBC) and Mean Red Cell Volume (MCV) decreased after Ramadan fasting (P= 0.002, P= 0.030 and P= 0.005, respectively), however mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) increased (P=0.004, P=0.002, respectively). On the other hand, no changes were seen in hemoglobin, platelets and white blood cell (WBC) after Ramadan (P=0.900, P=0.923, P=0.282, P=0.300, respectively).
In this study, fasting led to decrease in uric acid, creatinine, selenium, sodium and potassium (P=0.00, P=0.015, P=0.021, 0.007 and 0.028, respectively), however, phosphor serum increased after fasting period (P=0.032). Moreover, no changes were seen in other biochemical parameters including fast blood sugar (FBS), urea, calcium, iron, zinc, and albumin (P= 0.54, P=0.300, P=0.054, P=0.372, P=0.170, and P=0.400, respectively).
Conclusion:This study on healthy subjects suggests that fasting could affect some hematological-biochemical parameters but not all of them. Also, these changes in hematological-biochemical parameters were within the normal range and Ramadan fasting seems to be safe for healthy subjects.- انتشار مقاله: 10-01-1396
