Background & Objective: One of the post-operational problems in the cesarean-section is ileus symptoms and the starting point of taking the liquid diet. Some controversy are about this procedures. This study was done to evaluate the rate of ileus symptoms of women who are offered oral hydration shortly after cesarean delivery. Materials & Methods: This study involved 276 women delivered by cesarean under general anesthesia that had no previous cesarean or laparotomy and indisposing and their operations had not been exceeded 90 minutes. For these patients a liquid diet for every other day, partly 6 hours and others 12 hours after operation was started. The patients were examined at the time of starting diet and 6 hours later for bowel sound, nausea or vomiting, abdominal distention and gas passage. 138 women were assigned to each procedure. Results: Nausea or vomiting cases in the early fed group, were more than 12 hourly diets (2.2% versus no case) and (12.3% versus 10.9%) but the difference was not statistically significant. The bowel sound in the early fed group were less than 12 hourly starting the diets, (15.2% versus 12.3%) the difference was not statistically significant. The 6 hourly starting of liquid diet had a significant effect in speeding up bowel movements (P<0.05). Conclusion: Early oral hydration after cesarean was well tolerated and it was associated with rapid return of propulsive bowel movements, so to do, this results in better reply to the physiologic request of the patients.

Background and Objective: In recent years, the efficacy of low-fat diet has been questioned. One potential adverse effect of reduced dietary fat is a compensatory increase in the consumption of high glycemic index carbohydrate, principally refined starchy foods and concentrated sugar. Such foods other can be rapidly digested or transformed into glucose, causing a large increase in post-prandial blood glucose and insulin level. Review studies have generally found an inverse association between glycemic index and satiety. The aim of this study was to determine the effect of low-glycemic index diet versus low-fat diet on the body weight, body mass index, the percent of body fat mass and waist-hip ratio of obese women. Materials and Methods: In this randomized controlled trial study, 46 obese women with BMI>27 and 18-55 year old randomly divided into low-glycemic index and low-fat diet groups during the course of study and after 6-weeks, body mas index, body fat mass and waist-hip ratio were measured. Data analyzed with t student, t paired student tests. Results: Body weight, BMI, waist - hip ratio, and Triceps skinfold, biceps skinfold, subscapular skinfold, abdominal skinfold decreased significantly in both diet groups. After 6-weeks significant difference was not observed in percent of body fat mass between two dietary groups. Conclusion: This study showed that both low-glycemic index and low-fat diets can equally be effective in body fat, BMI and waist - hip ratio.

Background and Objective: Hypertension in long time can cause cardiovascular disorders and increase chance of stroke. This study was done to determine the association between some dietary factors and risk of hypertension. Methods: This cross-sectional study was conducted on the fourth phase (2008-11) of Tehran lipid and glucose study (TLGS). In this study 6089 subjects (2807 males and 3282 females), aged 19-70 years, were participated and dietary, demographic, anthropometric and blood pressure of each subject were collected. Dietary intake was assessed using a validated and reliable food frequency questionnaire with 147-items. Odds ratio for hypertension according to quartiles of dietary factors was determined using logistic regression with adjustment for confounder variables. Results: The rate of hypertension was 29.8%. Mean of weight, body mass index, waist circumference, prevalence of abdominal obesity and alliteration in the hypertensive subjects were significantly higher than normotensive subjects (P<0.05). There was a non significant direct relationship between energy density, total fat and saturated fat. Higher consumption of fiber was associated with lower risk of hypertension (OR: 0.62, 95% CI: 0.37-0.97). The risk of hypertension increased in the highest quartiles of dietary protein (OR: 1.20, 95% CI: 1.02-1.43). Odds ratio for hypertension was higher among subjects whom consumed lower fruits and nuts than those subjects with higher fruits consumption (OR: 1.33, 95% CI: 1.15-1.85) and nuts (OR: 1.21, 95% CI: 1.02-1.42). Conclusion: High consumption of fiber could protect against hypertension while some dietary factors such as high consumption of protein could increase risk of hypertension.

Background and Objective: Modification of life style, nutrional regiment and insulin therapy is used for improvement of pregnancy outcomes in pregnant women with gestational diabetes mellitus (GDM). This study was done to evaluate the effect of the dietary approaches to stop hypertension (DASH) eating plan on pregnancy outcomes in pregnant women with gestational diabetes mellitus. Methods: In this clinical trial study, 52 women with GDM were randomly divided into DASH and control groups for 4 weeks. The control diet contained 45-55% carbohydrates, 15-20% protein and 25-30% total fat. The DASH was rich in fruits, vegetables, whole grains and low-fat dairy products, and contained lower amounts of saturated fats, cholesterol and refined grains with a total of 2400 mg/day sodium. The numbers of women whom commenced insulin therapy after dietary intervention, the mode of delivery and prevalence of polyhydramnios were assessed. The length, weight and head circumference of infants were measured during the first 24 h after birth. Results: 46.2% of women in the DASH group needed to have a cesarean section, this rate for the control group was 80.8% (P<0.05). The percentage of those who needed to commence insulin therapy after intervention was 23% for DASH group vs 73% for controls (P<0.05). Infants born to mothers on the DASH group had significantly lower body weight (3222.7 vs 3818.8 g, P<0.05), head circumference (34.2 vs 35.1 cm, P<0.05) and ponderal index (2.50 vs 2.87 kg/m3, P<0.05) compared to those born to mothers on the control diet. Conclusion: Consumption of dietary approaches to stop hypertension for 4 weeks among pregnant women with GDM resulted in improved pregnancy outcomes.

Background and Objective: Overweight and obesity are increasing in the last three decades indicates the strong influence of environmental factors. Fats are the most important sources of human food which is considered as one of the reason for obesity. Among the components of the diet, poly unsaturated fatty acids (PUFA) are resulting in obesity. This study was done to evaluate the effect of diets containing poly unsaturated fatty acid on body weight and colon macroscopic properties in rabbit. Methods: In this experimental study, 24 female rabbits were allocated into three experimental groups including short, medium and long term and control groups (three subgroups). Animals in experimental groups were received diet containing corn oil for one month (short term), two months (medium term) and three months (long term). Animals at the end of the first, second and third months, were weighed and dissected and taken biopsy from colon. The macroscopic properties of the samples including shape and arrangement of Haustration were evaluated. Results: Over weight was not in the long – term consumption of corn oil in comparison with controls, but Haustra organization in different parts of the colon were disappeard in experimental animals. Conclusion: The diet containing poly unsaturated fatty acid causes macroscopic alteration in rabbit colon.

Background and Objective: The growing evidence suggest on the association between dietary patterns and obesity. This study was done to determine the relation between pattern of nutrient intake and obesity in Isfahanian adults.

Methods: In this descriptive - analytical study, dietary data were collected using a semi-quantitative food frequency questionnaire in 8,691 subjects aged 18-55 years. Complete data of 6,724 and 5,203 adults were available for general and abdominal obesity, respectively. Daily intakes of 38 nutrients and bioactive compounds were calculated for each participant. Factor analysis was applied to derive major nutrient patterns.

Results: Three major nutrient patterns were identified: 1) pattern high in fatty acids, cholesterol, vitamin B12, vitamin E, zinc, choline, protein, pyridoxine, phosphorus, and pantothenic acid; 2) high in thiamine, betaine, starch, folate, iron, selenium, niacin, calcium, and manganese; and 3) high in glucose, fructose, sucrose, vitamin C, potassium, dietary fiber, copper and vitamin K. Men in the highest quintile of the second pattern were less likely to be generally obese in the fully adjusted model (95% CI: 0.20-0.76, OR: 0.39, P<0.05). After adjustment for potential confounders, a significant positive association was observed between the third pattern and general obesity among men (95% CI: 1.04-3.04, OR: 1.77, P<0.05), but it was not in women (95% CI: 0.74-1.88, OR: 1.18, P>0.05).

Conclusion: Nutrient patterns were significantly associated with general, but not abdominal obesity in the male Iranians participating in SEPAHAN study.

Background and Objective: Aloe Vera is considered as one of herbs causes oxidative indexes modification due to antioxidant properties. On the other hands, High-fat diets (HFD) cause liver disorders prevalence. This study was done to evaluate the protective effect of hydro-alcoholic extract of Aloe Vera gel on enzymes and liver tissue structure of high-fat diet rats.
Methods: In this experimental study, 40 adult male rats were allocated in five groups including control, sham (HFD 10 ml/kg) and three experimental groups receiving HFD with doses of 150, 300 and 600 mg/kg/bw of Aloe Vera gel extract. Prescriptions were conducted by gavage and for 60 days. Blood samples were collected to measure AST, ALT and ALP enzymes. Liver removed subsequently and following preparing tissue sections liver cells were counted.
Results: High-fat diet significantly increased ALP and ALT enzymes (P<0.05). High-fat diet significantly increased the number of Kupffer cells and reduced of hepatocytes in compared to control group (P<0.05). High-fat diet caused liver tissue alterations including blood congestion, inflmation; Vacuole breakdown, apoptosis, and ballooning of hepatocytes. On the other hand, the consumption of Aloe Vera with high-fat diet caused reduction in tissue changes and a significant decrease in the serum levels of ALP and ALT enzymes in compared to control group (P<0.05).
Conclusion: High-fat diet by damaging the liver tissue  increased  the serum levels of ALP and ALT enzymes and Aloe Vera extract with its anti-oxidant characteristic prevent the effect of a high-fat diet on the liver tissue and reduced the ALP and ALT enzymes.

Background and Objective: Dietary acid load affects acid–base homeostasis, which may be associated with overweight and obesity as well as dietary quality index international (DQI-I), mean adequacy ratio (MAR), energy density (ED). This study was done to determine the association between dietary acid load with weight status and dietary quality indices among women.
Methods: This descriptive-analytic study was randomly performed on 306 women aged 20 to 55years. Dietary acid load was calculated by potential renal acid load (PRAL), net endogenous acid production (NEAP) and dietary acid load (DAL). DQI-I, MAR, ED were estimated for the participants.
Results: The probability of obesity (95% CI=0.97-5.50, OR=2.33, P=0.04), as well as abdominal adiposity (95% CI=1.21-4.50, OR=2.4, P=0.005) was significantly increased with tertile of DAL (P<0.05). While even after control of confounder variables, other dietary acid load indices (PRAL and NEAP) showed no significant association between dietary acid load and obesity, overweight or abdominal obesity. Also ,with increasing dietary acid load scores, DQI-I and MAR significantly decreased whereas energy density showed a significant increased across tertile categories of dietary acid load indices (P<0.05).
Conclusion: DAL was associated with increased risk of obesity and abdominal obesity. PRAL, NEAP and DAL were good indicators of diet quality indices.

Background and Objective: Atorvastatin is a member of the statin family with lipophilic character and anti-hyperlipidemic effect. There is many evidence that atorvastatin has protective effect on cognitive function. This study was done to evaluate the effect of atorvastatin on spatial memory in rats following a high-fat diet.
Methods: This experimental study was performed on 35 male Wistar male rats. Animals were randomly allocated into 5 groups including control, control plus atorvastatin and sham (received high-fat diet for 4 weeks) and high-fat diet plus atorvastatin (10 and 50 mg/kg, for 4 weeks). Learning and spatial memory were measured using Morris water maze for a 6-day period including 5 days training and the last day, test day (probe day).
Results: High-fat diet reduced learning and poor memory performance during training and probe compared to the control group, and also on the probe day, the high-fat group spent less time in the target quarter (P<0.05). Administration of atorvastatin after a high-fat diet improvement spatial memory in compared to high-fat group (P<0.05).
Conclusion: Short-term treatment (4 weeks) with atorvastatin in high-fat dietary rats can improve spatial memory.

Background and Objective: Celiac disease is a malabsorption disorder that could result in various psychological consequences if patients do not adhere to a gluten-free diet. This study aimed to determine the frequency of major depressive disorder and its relationship with adherence to a gluten-free diet among patients with celiac disease.
Methods: This descriptive-analytical study was conducted on 47 patients with celiac disease (30 women and 17 men) with an average age of 40.88 ± 10.7 years who had been referred to the Golestan Research Center of Gastroenterology and Hepatology during the summer of 2019. Patients were invited to complete a 13-item Beck Inventory. Celiac Dietary Adherence Test (CDAT) was used to assess adherence from the patients' point of view, and Standardized Dietician Evaluation (SDE) was used to evaluate adherence to the diet from the interviewer's perspective.
Results: Overall, 28 people (59.6%) with celiac disease reported some degree of depression. Based on the SDE, the adherence rate of patients to a gluten-free diet was 83%. The association between adherence to a gluten-free diet and the prevalence of depression was not significant. There was also no significant association between the prevalence of depression and the gender and age of patients.
Conclusion: Based on the results, a high percentage of patients with celiac disease have symptoms of depression. However, there is no significant relationship between adherence to a gluten-free diet and the prevalence of depression.
