Evaluation of the relationship between dietary acid load and cardiovascular risk factors in patients with type 2 diabetes: a case-control study.

Backround: Diets high in dietary acid load are thought to be associated with metabolic diseases. However, the number of studies examining the relationship between dietary acid load and metabolic diseases in Turkey is insufficient. The aim of this study was to investigate the relationship between cardiovascular disease risk factors and dietary acid load in individuals with type 2 diabetes. Materials and methods: In this case-control study, 51 participants aged 30-65 years with type 2 diabetes and 59 participants in the control group were included. Blood pressure and biochemical findings were measured. Anthropometric measurements and body composition measurements were made. Dietary intake was assessed using a 3-day (1 day on weekends, 2 days on weekdays) food consumption record. Dietary acid load scores, including potential renal acid load (PRAL) and net endogenous acid production (NEAP), were calculated based on dietary intake. NEAP and PRAL scores were categorized as low and high according to the median value. Smoking status, body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), total cholesterol (TC), trigylceride (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL), waist-hip ratio (WHR), waist-to- height ratio (WtHR), hemoglobin and fat mass (%) were evaluated as cardiovascular risk factors. Results: The cut-off values of PRAL and NEAP were 3.61 and 44.78 mEq/d, respectively. After adjustment for various covariates, a significant positive association between PRAL and TG levels was observed in the diabetic group [odds ratio (OR), 5.98; 95% CI, 1.45-24.67; p = 0.013]. In contrast, a negative association was found between PRAL and SBP in the control group [odds ratio (OR), 0.21; 95% CI, 0.05-0.83; p = 0.026]. However, these associations were not observed for NEAP values in either group. Conslusions: A higher PRAL value was consistently associated with higher TG level, but other cardiovascular risk factors were not. More longitudinal and interventional studies are needed to better establish a causal effect between dietary acid load and cardiovascular risk factors in individuals with diabetes.

Effects of Nutritional Knowledge of Informal Caregivers on Depression and Metabolic Outcomes of Hemodialysis Patients.

Chronic renal failure (CRF) makes significant changes in the life of patients and their families. A good family support has a positive effect on successful patients' adaptation to the treatment and compliance with dietary regimen. This study aimed to examine the effects of nutritional knowledge of informal caregivers on depression and metabolic outcomes of hemodialysis patients. This was a cross-sectional study conducted at Baskent University Hemodialysis Center with 116 hemodialysis patients and their informal caregivers. Findings revealed that the caregivers who were the couple of the patients had the highest nutritional knowledge level than the other caregivers (p < .05). The postgraduate caregivers were more likely to have high nutritional knowledge level than the others (p < .05). The inflammation marker of the patients was significantly lower in the group of caregivers with higher level (T3 group) of nutritional knowledge than the others (p < .05). The mean CES-D scores were also more likely to be low in T3 group than in the others (p < .05). These findings highlight that the nutritional knowledge of caregivers of hemodialysis patients may have an additional benefit on patients' nutritional management and metabolic outcomes.

Determining the relationship between dietary iodine intake, urinary iodine excretion and thyroid functions in people with type 2 diabetes mellitus

ABSTRACT Objective Type 2 diabetes mellitus (T2DM) is a worldwide health problem, and medical nutrition therapy is essential for improving the quality of life of patients with type 2 diabetes. Salt restriction may lead to iodine deficiency in these patients. Moreover, type 2 diabetes can be an indirect reason for thyroid disorders. This study was conducted to determine the relationship between dietary iodine intake, urinary iodine excretion and thyroid functions in people with T2DM. Materials and methods Iodine nutritional status was determined by a one day 24-h dietary recall and food-frequency questionnaire. Iodine status was detemined by urinary iodine excretion with morning urine sample. Results Iodine intake according to one day 24-h dietary recall was lower in T2DM patients [94.8 (76.0-112.0) μg] than people in control group [137.1 (123.1-165.4) μg] (p < 0.05). Iodine intake determined by food-frequency questionnaire rich in iodine was lower in T2DM patients [93.1 (84.4-113.9) μg] than people in control group [140.2 (125.1-166.1) μg] (p < 0.05). Mild iodine deficiency was found in %38.8 of diabetic and %55.1 of healthy individuals (p < 0.05). No significant relationship was found between urinary iodine excretion and thyroid function tests in groups (p > 0.05). However, the relationship between dietary iodine excretion and urinary iodine intake in the diabetic group was lower than in the control group (p < 0.05). Conclusion With this respect, the results showed that while planning medical nutrition therapy for diabetic individuals, the risk of iodine deficiency should be considered.

Is neck circumference measurement an indicator for abdominal obesity? A pilot study on Turkish Adults.

BACKGROUND: Neck circumference (NC) measurement is one of the simple screening measurements which can be used as an index of upper body fat distribution to identify obesity. OBJECTIVES: The aim of this study was to determine the relationship between neck circumferences and obesity. METHODS: A total 411 volunteer adults participated in this study (174 men, 237 women). A questionnaire which consisted of anthropometric measurements and demographic features was used. Patients with NC ≥37 cm for men and ≥34 cm for women require evaluation of overweight status. RESULTS: The percentages of the men and women with BMI ≥ 25 kg/m(2) were 55.2% and 27.0% respectively and with high neck circumferences were 85.1% and 38.8%, respectively. The percentages of the men and women with high waist circumference were 31.6% and 79.3%, respectively. In both gender there were positive significant correlations between neck circumference, body weight (men, r=0.576; women, r=0.702; p=0.000), waist circumferences (men, r=0.593; women r=0.667; p=0.000), hip circumferences (men, r=0.568; women, r=0.617; p=0.000) and BMI (men, r=0.587; women, r=0.688; p=0.000). CONCLUSIONS: This study indicates that NC was associated with body weight, BMI, waist and hip circumferences and waist/hip ratio for men and women. A significant association was found between NC and conventional overweight and obesity indexes. NC was associated with waist/hip ratio for men and women.

Nutritional status and anthropometric measurements of patients with multiple sclerosis.

OBJECTIVE: To determine the nutritional status and anthropometric measurements of patients with multiple sclerosis (MS). METHODS: This research was conducted on 37 (15 men, 22 women) new diagnosed MS patients who applied to Ankara Numune Education and Research Hospital, Ankara Turkey, from June to August 2011. The nutritional status of patients was determined by a 3-day and 24-hour dietary record and a food frequency questionnaire. Body composition was analyzed by bioelectrical impedance analyzer, and body mass index was calculated. The Nutrient Data Base (BEBIS) program was used to evaluate the energy and nutrient intakes of patients and compared with Dietary Reference Intakes recommendations. Blood samples were collected and serum glucose, lipid profiles, total protein, albumin, total calcium, magnesium, vitamin B12, and vitamin D levels were analyzed. RESULTS: Approximately 5.4% of patients were underweight, 54.1% were normal weight, 24.3% were overweight and 16.2% were obese. Daily mean energy intakes were 2730+/-840.97 kcal in men and 1967+/-647.24 kcal in women. The percentage of the carbohydrates was 46.9%, proteins was 14.6%, and fats of the total energy was 38.4%. Approximately 16.7% of the patients' serum vitamin D, and 6.7% of the patients' serum vitamin B12 levels were below than the reference ranges. CONCLUSION: Multiple sclerosis patients have high body mass index values and poor nutritional status. It was verified that life style modification with adequate and balanced nutritional habits is very important in MS patients.

Enteral nutrition via percutaneous endoscopic gastrostomy and nutritional status of patients: five-year prospective study.

BACKGROUND: Since it was described in 1980, percutaneous endoscopic gastrostomy (PEG) has been a widely used method for insertion of a gastrostomy tube in patients who are unable to swallow or maintain adequate nutrition. The aim of the present paper was to determine the complications of PEG insertion and to study pre- and post-procedural nutritional status. METHODS: During the period of March 1999-September 2004, placement of PEG tube was performed in 85 patients (22 women and 63 men). Patient nutritional status was assessed before and after PEG insertion via anthropometric measurements. RESULTS: The most frequent indication for PEG insertion was neurological disorders (65.9%). Thirty patients died due to primary disease and two patients due to PEG-related complications within 5 years. There were 14 early complications in 10 patients (15.2%; <30 days), and 18 late complications in 12 patients (19.6%). Total mortality was 37.6%. All complications other than four were minor. Before PEG insertion, patients were assessed with subjective global assessment and it was determined that 43.2% of them had severe, and 41.9% of them had mild malnutrition. After PEG insertion, significant improvements on patient nutrition levels was observed. CONCLUSION: Percutaneous endoscopic gastrostomy is a minimally invasive gastrostomy method with low morbidity and mortality rates, is easy to follow up and easy to replace when clogged.

Acute pancreatitis possibly due to arginine use: a case report.

Arginine has been used by millions of athletes over the past 20 years to enhance production of human growth hormone. The effects of arginine supplementation include increased fat burning and muscle building, enhanced immunity, and improvement in erectile function in men. Excessive doses of basic amino acids such as ethionine, methionine and lysine are known to damage the rat pancreas. Recent studies have demonstrated that excessive doses of arginine induce necrotizing pancreatitis in rats. In this article, we report a 16-year-old male patient hospitalized in our clinic because of severe pain in upper abdomen, nausea and vomiting who was suspected to have arginine-induced acute pancreatitis.
