Cognitive performance was evaluated by the Consortium to Establish a Registry for Alzheimer’s disease (CERAD) word learning and recall modules, the animal fluency test (AF), and the digit symbol substitution test (DSST). Participants who scored the lowest 25th percentile were categorized in the LCP group. The Dietary Interview-Total Nutrient Intakes dataset was used to determine the dietary intake of B vitamins in the participants. The low intake group and adequate intake group were differentiated based on the recommended dietary allowance. Subgroup analyses were conducted to assess the relations between 3 B vitamins and cognitive performance among different sex, race, and age groups.Results: Compared with low vitamin B6 intake (< 1.7 mg/day), adequate vitamin B6 intake (≥ 1.7 mg/day) corresponded to a 31.7% decrease in LCP odds in the DSST tests. Participants who consumed adequate B9 (≥ 400 mcg/day) were associated with 31.2%, 33.8%, and 46.5% declines in the risk of LCP in the CERAD, AF, and DSST tests in contrast to those having low B9 intake (< 400 mcg/day). Adequate vitamin B12 intake (≥ 2.4 mcg/day) correlated with a lower LCP occurrence in the CERAD, AF, and DSST tests, with 30.5%, 21.5%, and 33.3% reductions, respectively. Further, the relations between 3 B vitamins and cognitive performance varied across different sex, race, and age groups of people.Conclusion: Adequate dietary vitamin B9 and B12 intakes are significantly associated with a better cognitive performance in immediate and delayed memory recall, categorical verbal fluency, processing speed, sustained attention, and working memory among elders assessed in the CERAD, AF, and DSST tests.Keywords: vitamin B6, pyridoxine, B9, folate, B12, cobalamin, cognition, National Health and Nutrition Examination, NHANES, dietary intake

Introduction: bariatric surgery is a treatment for morbid obesity that besides result in high weight loss promotes improvements in laboratory tests and in the pressure reduction. However the surgery can cause bad effects as deficiency some nutrients. This fact become more important evaluates the adequacy of dietary intake of these patients. The objective this study was evaluates the adequacy dietetic of patients after bariatric surgery. Material and methods: we select forty women who underwent Roux-en-Y gastric and carried evaluation anthropometric and dietetic. The dietary evaluate was compared with the daily consumption requirement and food pyramid for these patients. Results: forty women with 43.1 ± 9.96 years, obesity and very high risk for metabolic complications associate with obesity, and with acceptation of supplementation (95%) participated this study. The majority of women consumed group’s foods “high-calorie foods, fats and sweets are energy-dense foods” and showed high intake of foods groups “grains and cereals” and “high-fiber, low-calorie foods”. Dietary intake was low-calorie (1342.50 ± 474.06 Kcal), adequate in protein (22.10 ± 6.94%), carbohydrate (50.74 ± 10.96%), lipid (26.14 ± 7.17%), saturated fatty acids (8.69 ± 2.74%) and polyunsaturated fatty acids (8.93 ± 3.51%) and low-monounsaturated fatty acids (4.13 ± 1.78%) and fibers (17.02 ± 10.64 g). Conclusions: nutritional habits of women showed inadequacy, these results reinforce the importance of nutritional accompanying in the late postoperative bariatric surgery.

Cardiovascular disease (CVDs) is the leading cause of morbidity and death worldwide. Most genetic variants could be identified by several genome-wide-association-studies (GWAS), including within genes encoding proteins involved in the AKT/PI3K pathways that are related with an increased risk of metabolic syndrome and CVDs. Therefore, due to the importance of genetic variants in the prognosis of diseases, we examined the genetic polymorphism of AKT-rs1130233 located on chromosome 14 with cardiovascular risk factors. In this cross-sectional study, 721 subjects recruited from the Mashhad-Stroke and Heart-Atherosclerotic-Disorders (MASHAD) cohort study. The participants including 257 subjects with metabolic syndrome, 144 subjects with cardiovascular disease and 320 subjects as a control group. Anthropometric, biochemical and demographic information measures were prepared. Dietary assessment was managed by 24h dietary recall. DNA extraction and genotyping were carried out by using the TaqMan real-time-PCR based method. The association of AKT rs1130233 locus with dietary intakes, metabolic syndrome and cardiovascular risk factors were assessed. Data were analyzed by using SPSS 21 software. Frequencies of genotypes AA, AG and GG of the AKT rs1130233 polymorphism were 12.6%, 44.5% and 42.9% in subjects with metabolic syndrome and 9.7%, 39.6% and 50.7% in subjects with cardiovascular disease, respectively. The frequency of allele A and G in cardiovascular disease and metabolic syndrome population were 29.5%, 70.5% and 34.8%, 65.2%, respectively. We have found no significant association between the AKT rs1130233 polymorphism with cardiovascular risk factors and metabolic syndrome. The results of dietary intake showed that the levels of phosphorus intake (p=0.008), calcium intake (p=0.007) and iodine intake (p=0.04) were different in subjects with and without metabolic syndrome. And also, energy intake was significantly different in subjects with cardiovascular disease (p=0.01) compared to the control group. Our findings suggest that AKT rs1130233 was not associated with the risk of metabolic syndrome and cardiovascular disease in the Iranian population. More studies are needed to validate our results. We did functional analysis, due to certify our investigation about value of this genetic biomarker for CVD risk.
