Comparison of dietary inflammatory index and total antioxidant capacities of familial Mediterranean fever and healthy adolescents.

BACKGROUND: Although it is known that consumed nutrition affects inflammatory load, and total antioxidant capacity (TAC) is affected by inflammatory diseases and consumed nutrients, these conditions have not been adequately investigated in adolescents with familial Mediterranean fever (FMF). Therefore, this study aimed to compare the dietary inflammatory index (DII), TAC and total oxidant capacity (TOC) of adolescents with FMF and healthy adolescents. METHODS: This case-controlled study consisted of 180 adolescents (aged 10-19) divided into FMF (n = 135) and control (n = 45 healthy) groups. Study data were collected face-to-face using a survey on demographic characteristics, anthropometric measurements, biochemical biomarkers and 3-day dietary recall to calculate DII scores. RESULTS: FMF group had lower DII score than controls (2.12 ± 0.78 vs. 2.33 ± 1.06, p < 0.05). In addition, they had higher C-reactive protein (CRP), TOC (p < 0.05) and oxidative stress index (OSI) (p = 0.51) than the control group. On the contrary, the control group had significantly higher tumour necrosis factor-α (TNF-α) and interleukin-6 (IL-6) values (p < 0.05). There was a positive correlation between DII scores and TNF-α in the FMF group (p < 0.05). The control group had significantly higher energy, protein, medium-chain fatty acids (MCT) and saturated fatty acids (SFA) intake than FMF (p < 0.05). On the contrary, the FMF group had significantly higher vitamin A and D, niacin and zinc intake (p < 0.05). CONCLUSION: The results showed that adolescents with FMF had lower DII and higher OSI than healthy adolescents. It may be beneficial for adolescents with FMF to consume a diet containing anti-inflammatory nutrients to maintain normal growth and development and to prevent symptoms and complications of the disease.

Association Between Magnesium Status, Dietary Magnesium Intake, and Metabolic Control in Patients with Type 2 Diabetes Mellitus.

BACKGROUND: Hypomagnesemia could worsen glycemic control by impairing insulin release and promoting insulin resistance. On the contrary, type 2 diabetes mellitus (T2DM) may induce and/or exacerbate low serum magnesium levels, and this could, in turn, worsen glycemic control of diabetes. OBJECTIVE: The aim of this study was to investigate the relationship between serum magnesium level, dietary magnesium intake, and metabolic control parameters in patients with T2DM. METHODS: The study included 119 patients with T2DM (26 male, 93 female; mean age 54.7 ± 8.4 years). Serum magnesium level was measured by spectrophotometric method. Magnesium intake was assessed by food frequency questionnaire. Anthropometric measurements were taken. The General Linear Model procedure was applied to determine the relationship of serum magnesium with quantitative variables. RESULTS: Of the 119 patients, 23.5% of the patients had inadequate magnesium intake (lower than 67% of the recommended daily allowance), and 18.5% had hypomagnesemia. In patients with hypomagnesemia (< 0.75 mmol/l), serum levels of fasting plasma glucose (FPG), postprandial plasma glucose (PPG), and serum glycosylated hemoglobin (HbA1c) were higher compared to patients with normomagnesemia. FPG levels were significantly higher in patients with hypomagnesemia in Model 1 (179.0 ± 64.9 vs. 148.7 ± 52.0 mg/dl, p = 0.009) but the significance disappeared in other models. PPG levels were significantly higher in patients with hypomagnesemia in all models (287.9 ± 108.4 vs. 226.8 ± 89.4 mg/dl, p = 0.006 for Model 1, p = 0.027 for Model 2, p = 0.016 for Model 3). Serum HbA1c levels were significantly higher in patients with hypomagnesemia, and this significance proceeded (8.0 ± 1.9% vs. 6.5 ± 1.2%, p = 0.000 for all models). Body fat mass was significantly higher in patients with hypomagnesemia as compared to patients with normomagnesemia in model 3 (35.4 ± 9.4 kg, 34.6 ± 10.2 kg; p = 0.034). Dietary magnesium intake was not significantly associated with either metabolic parameters or anthropometric measurements. CONCLUSION: Hypomagnesemia in T2DM is directly associated with poor metabolic control. Clinical assessment should, therefore, focus on augmentation of magnesium status and adequate magnesium intake in patients with T2DM.

Urinary oxalate to creatinine ratios in healthy Turkish schoolchildren.

AIM: we aimed to establish reference values for urinary oxalate to creatinine ratios in healthy children aged 6-15 years and to investigate the relationship between their nutritional habits and oxalate excretion. MATERIALS AND METHODS: Random urine specimens from 953 healthy children aged 6-15 years were obtained and analyzed for oxalate and creatinine. Additionally, a 24-h dietary recall form was prepared and given to them. The ingredient composition of the diet was calculated. The children were divided into three groups according to age: Group I (69 years, n = 353), Group II (10-12 years, n = 335), and Group III (13-15 years, n = 265). RESULTS: The 95th percentile of the oxalate to creatinine ratio for subjects aged 6-9, 10-12, and 13-15 years were 0.048, 0.042, and 0.042 mg/mg, respectively. The oxalate to creatinine ratio was significantly higher in Group 1 than in Group 2 and Group 3. Urinary oxalate excretion was positively correlated with increased protein intake and negatively correlated with age. A significant positive correlation was determined between urinary oxalate excretion and the proline, serine, protein, and glycine content of diet. Dietary proline intake showed a positive correlation with the urine oxalate to creatinine ratio and was found to be an independent predictor for urinary oxalate. CONCLUSIONS: These data lend support to the idea that every country should have its own normal reference values to determine the underlying metabolic risk factor for kidney stone disease since regional variation in the dietary intake of proteins and other nutrients can affect normal urinary excretion of oxalate.

The effects of implementing a nutritional support algorithm in critically ill medical patients.

OBJECTIVE: To determine the effect of the enteral nutrition algorithm on nutritional support in critically ill medical patients. METHODS: The quasi-experimental study was conducted at a medical Intensive Care Unit of a university hospital in central Anatolia region in Turkey from June to December 2008. The patients were divided into two equal groups: the historical group was fed in routine clinical applications, while the study group was fed according to the enteral nutritional algorithm. Prior to collecting data, nurses were trained interactively about enteral nutrition and the nutritional support algorithm. The nutrition of the study group was directed by the nurses. Data were recorded during 3 days of care. SPSS 22 was used for statistical analysis. RESULTS: The 40 patients in the study were divided into two equal groups of 20(50%) each. The energy intake of study group was 62% of the prescribed energy requirement on the 1st, 68.5% on the 2nd and 63% on the 3rd day, whereas in the historical group 38%, 56.5% and 60% of the prescribed energy requirement were met. The consumed energy of the historical group on the 1st 2nd and 3rd day was significantly different (p=0.020). In the study group, serum total protein and albumin levels decreased significantly (p<0.05), but pre-albumin and fasting blood glucose levels were not changed on the 1st and 4th day. In the historical group, any of the serum parameters did not change. Enteral nutrition-induced complications, duration of stay in intensive care unit were not significantly different between the groups (p>0.05). CONCLUSIONS: The use of standard algorithms for enteral nutrition may be an effective way to meet the nutritional requirements of patients.

Impact of Omega-3 and Omega-9 fatty acids enriched total parenteral nutrition on blood chemistry and inflammatory markers in septic patients.

OBJECTIVE: Lipid emulsions containing omega-3 are known to have positive effects on patient's prognosis due to anti-inflammatory properties. The aim of this study was to investigate the effects of omega-3 enriched total parenteral nutrition (TPN) emulsion containing omega-9 on biochemical parameters, inflammatory mediators in septic patients. METHODS: Thirty-two participants who were not fed orally for over five days and needing TPN support were included in this prospective, randomized and double-blind clinical study. Patients were randomly divided into control (n=16), treatment (n=16) groups. The treatment group received TPN containing 80% olive oil+20% soy oil additionally 10 g fish oil enriched TPN. Control group received only olive oil containing standard lipid emulsion (1.3±0.1 g/kg/day). Blood samples were collected for biochemical analysis on the 1(st) and 6(th) days of study. RESULTS: The serum albumin levels significantly increased (p<0.05) in both groups whereas total protein and prealbumin levels did not show any significant changes. In treatment group, significant decreases were determined in LTB4 and CRP levels (p<0.05) while decreases in IL-6, TNF-α and leukocyte levels were not significant. No statistically significant changes were found in LTB4, CRP, IL-6, TNF-α and leukocyte levels of controls. CONCLUSION: RESULTS of the study have shown that omega-3 enriched TPN solution containing omega-9 contributes to decrease in the levels of inflammatory mediators and to improvement in the biochemical parameters in septic patients.

Determination of the effectiveness of the three-minute nutrition screening (3-MinNS) tool in adult patients hospitalized in a cardiology clinic.

OBJECTIVES: To determine the efficacy of the 3-Minute Nutrition Screening (3-MinNS) tool in adults hospitalized for cardiovascular diseases. METHODS: In this descriptive cross-sectional study of 759 cardiovascular disease patients in Erciyes University Cardiology Clinic, anthropometric measurements and some routine biochemical parameters were recorded, and nutrition screening tools were used to determine malnutrition status. The power of 3-MinNS to detect malnutrition in cardiovascular diseases patients was calculated. RESULTS: There was a strong positive correlation between 3-MinNS and Nutrition Risk Screening-2002 (NRS-2002) (r=0.719, p<0.001). A moderate agreement was found between 3-MinNS and NRS-2002 (κ=0.496, p<0.001). The sensitivity, specificity, and AUC of 3-MinNS were 79.1%, 75.0%, and 0.851, respectively, and it was determined to be a moderately effective nutrition screening tool that can be used to identify malnutrition in patients with cardiovascular diseases. CONCLUSION: The 3-MinNS is a moderately effective nutrition screening tool that can be administered within the first 24 hours of hospitalization in patients with cardiovascular diseases.

Effects of probiotic supplementation on very low dose AFB1-induced neurotoxicity in adult male rats.

AIMS: Aflatoxin B1 (AFB1) is the most toxic and common form of AF found in food and feed. Although AFB1 exposure has toxic effects on many organs, studies on the brain are limited. Moreover, to the best of our knowledge, there is no study on the effect of probiotics on AFB1-induced neurotoxicity. Therefore, we aimed to evaluate the possible effects of probiotics on AFB1-induced neurotoxicity in the brain. MAIN METHODS: Thirty-two adult male Wistar rats were divided into four groups: Vehicle (VEH), Probiotic (PRO) (2.5 × 1010 CFU/day VSL#3, orally), Aflatoxin B1 (AFB1) (25 µg/kg/week AFB1, orally), and Aflatoxin B1 + Probiotic (AFB1 + PRO) (2.5 × 1010 CFU/day VSL#3 + 25 µg/kg/week AFB1, orally). At the end of eight weeks, rats were behaviorally evaluated by the open field test, novel object recognition test, and forced swim test. Then, oxidative stress and inflammatory markers in brain tissues were analyzed. Next, brain sections were processed for Hematoxylin&Eosin staining and NeuN and GFAP immunostaining. KEY FINDINGS: Probiotic supplementation tended to decrease oxidative stress and inflammatory markers compared to the AFB1 group. Besides, brain tissues had more normal histological structures in VEH, PRO, and AFB1 + PRO groups than in the AFB1 group. Moreover, in probiotic groups, GFAP immunoreactivity intensity was decreased, while NeuN-positive cell number increased in brain tissues compared to the AFB1 group. SIGNIFICANCE: Probiotics seem to be effective at reducing the neurotoxic effects of AFB1. Thus, our study suggested that especially Bifidobacterium and Lactobacillus species can improve AFB1-induced neurotoxicity with their antioxidant and anti-inflammatory effects.

A Comparison of Cognitive Functions and Nutritional Status in Nursing Home Residents and Community-Dwelling Elderly.

Objective: This descriptive and comparative study was conducted to determine the cognitive functions and nutritional status of nursing-home-residing and community-dwelling elderly. Methods: The study was carried out with a total of 204 elderly people who were community dwelling (n = 104) and nursing home residents (n = 100). Data were collected with the Mini Nutritional Assessment (MNA) and standardized with the Mini Mental State Examination (MMSE). Results: Mean age of the nursing home residents and community-dwelling elderly people was 77.4 (SD = 6.7) years and 76.5 (SD = 7.4) years, respectively. Mean MMSE score was significantly different between nursing home residents (18.5 [SD = 4.5]) and community-dwelling elderly (22.1 [SD = 4.7]) (P < .05). Mean MNA score of nursing home residents (23.0 [SD = 3.7]) and community-dwelling elderly (24.6 [SD = 3.1]) was significantly different (P < .05). Conclusion: Nursing home residents were at risk of malnutrition and cognitive impairment. Precautions for the protection of the residents for maintaining nutritional status and cognitive functions were recommended.

Urinary uric acid : creatinine ratios in healthy Turkish children.

BACKGROUND: Determining uric acid : creatinine ratios in random urine samples may be useful to assess the excretion of uric acid in children. Because it was shown that urinary uric acid excretion varies with age and geographic area, it is important to have accurate reference values of uric acid excretion. The aim of the present study was therefore to obtain regional reference values for urinary uric acid : creatinine ratios in healthy Turkish children. METHODS: A total of 1306 children aged 1 month-15 years were analyzed for uric acid and creatinine, and urinary uric acid : creatinine ratios were determined from each sample. The second non-fasting morning urine samples were taken from all the children. Urine samples were analyzed for uric acid using the uricase method, and for creatinine with the Jaffe reaction. RESULTS: The mean +/- SD and 5th-95th percentiles of urinary uric acid : creatinine ratios (mg/mg) were 1.09 +/- 0.48 and 0.27-1.87 at 1-6 months, 0.86 +/- 0.41 and 0.19-1.64 at 7-12 months, 0.76 +/- 0.32 and 0.32-1.43 at 1-3 years, 0.63 +/- 0.29 and 0.20-1.23 at 4-6 years, 0.44 +/- 0.24 and 0.14-0.93 at 7-11 years, and 0.30 +/- 0.14 and 0.12-0.62 at 12-15 years. Uric acid : creatinine ratios were not significantly different between boys and the girls except at 12-15 years. Girls aged 12-15 years had higher urinary uric acid : creatinine ratio when compared with boys (P < 0.05). There was no correlation between urinary uric acid : creatinine ratio and protein intake. CONCLUSIONS: Urinary uric acid : creatinine ratio changes with age. When assessing urinary uric acid : creatinine ratio, the clinician should consider the age of the child.

A face-to-face interviews was conducted with 203 patients. Results showed that 32% and 18.2% of the patients used herbs or vitamin/mineral supplements, respectively. Nettle was the most commonly used herb, and iron and vitamin C were the most commonly used supplements. There was a significant difference between herb or vitamin/mineral users and nonusers with regard to educational levels. In conclusion, patients with cancer highly tended to use herb or vitamin/mineral supplements.

Obesity prevalence, waist-to-height ratio and associated factors in adult Turkish males.

SUMMARY: This study was performed to determine the obesity prevalence and associated risk factors in aged 20 and over years old males living in 11 towns in Kayseri, Turkey between July and August 2007. 1530 men were recruited, of which 6 were excluded because of incomplete information. Data were collected by a questionnaire. Body weight, height, waist and hip circumferences were measured. Body mass index (BMI) of 25.0-29.9 kg/m(2) was accepted as overweight and above 30 kg/m(2) as obesity, waist-to-hip ratio (WHpR) > 1.0 and waist-to-height ratio (WHtR) ≥ 0.5 were accepted as abdominal obesity. Chi-square and logistic regression tests were performed. According to BMI, overweight and obesity prevalences were 39.6% and 16.9%, respectively. Obesity prevalence was 29.9% (50-59 years) according to WHpR, 50.4% (60-69 years) according to waist circumference (WC) and 24.8% (40-49 years) according to WHtR. The logistic regression analysis revealed age of 60-69 years, being a graduate from university, being widowed and having positive familial history of obesity as risk factors of having BMI ≥ 25 kg/m(2). In conclusion, obesity is a serious issue for the males residing in Kayseri and among the anthropometric measurements WHtR is a simple and effective index to identify health related risks even in male of younger ages.:

Bone mineral density and serum 25-hydroxyvitamin D level: is there any difference according to the dressing style of the female university students.

Nutrition plays a role in the etiology of osteoporosis. Two of the most important nutrients for bone health are calcium and vitamin D. Plasma 25-hydroxyvitamin D [25-(OH)D] is the most sensitive clinical index of vitamin D status and has been found to be positively related to bone mineral density (BMD) in middle-aged and elderly women, and positive relations exist between the BMD of adult women and their calcium consumption throughout life. The aim of the present study was to determine relationships between BMD, serum vitamin D levels and dietary calcium intake of female young adult students who dressed in different styles. We studied two groups of volunteer female students (total = 67). Students in the first group dressed in a style that exposed the skin to sunlight, students in the second group wore dresses completely covering the skin except for the face and hands. Serum 25-(OH)D levels were measured by radioimmunoassay, BMDs were determined at the lumbar spine and femoral neck by dual-energy X-ray absorptiometry, and calcium intakes were estimated with a 3-day food recording questionnaire. The serum 25-(OH)D level was significantly lower in the second group. There was no significant difference in BMD between the two groups. The dietary calcium intake of the two groups were lower than the adequate intake of 1000 mg daily for this age. There was a correlation between the serum 25-(OH)D level and BMD at the femoral neck in the first group. Our results indicate that vitamin D and calcium requirements for normal bone mineral accrual in young adults may advance until a certain age, and the covered dressing style causes vitamin D insufficiency and most of the students were under risk for osteoporosis in later life.

Use of olive oil based emulsions as an alternative to soybean oil based emulsions in total parenteral nutrition and their effects on liver regeneration following hepatic resection in rats.

BACKGROUND/AIM: The main objective of this study was to compare the effects of olive oil to those of soybean oil on liver tissue regeneration following hepatic resection in rats. METHODS: Seventy albino Wistar rats were randomly assigned to seven groups which contained 10 rats each. Group 1 was the sham-treated group; groups 2 and 3 received total parenteral nutrition (TPN) containing soybean oil lipid emulsions (20% Lipofundin MCT/LCT) for 48 or 72 h; groups 4 and 5 received TPN containing olive oil (80%)/soybean oil (20%) lipid emulsions (ClinOleic 20%) for 48 or 72 h; group 6 was the control group for 48 h, and group 7 was the control group for 72 h. TPN was given via internal jugular vein, and 70% hepatic resection was performed in the study groups. In addition, hepatic resections with no TPN were performed in the control groups, except the sham group. Relative liver weight, mitotic index, proliferating cell nuclear antigen labeling index, and carnitine levels in liver tissue samples were used to assess hepatic regeneration. Thiobarbituric acid reactive substances were measured as an index of lipid peroxidation and oxidative tissue damage. Alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase were parameters for the liver function. RESULTS: The relative liver weight increased significantly with minimal hepatosteatosis in the olive oil treated groups. Lipid peroxidation significantly decreased with near-normal serum levels of the liver function parameters in the olive oil/soybean oil treated groups, and mitotic index and proliferating cell nuclear antigen labeling index reached their maximum level in rats receiving TPN containing any kind of lipid emulsions for 48 h following resection. CONCLUSIONS: The use of olive oil/soybean oil lipid emulsions in TPN has important beneficial effects on the liver regeneration, and the antioxidant properties of olive oil originating from its natural components indirectly contribute to the liver regeneration in rats.
