New-onset coeliac disease in children during COVID-19 outbreak.
Besides, higher variety in fruit and vegetable consumption was associated with lower prevalence of having an inadequate intake of fiber [(0.13 (0.11-0.16)], two or more [(0.17 (0.14-0.21)], three or more [(0.15 (0.13-0.18)] and four or more [(0.11 (0.10-0.14)] micronutrients in our participants. Higher quantity and variety in fruit and vegetable consumption was associated with lower prevalence of having an inadequate intake of fiber [(0.05 (0.04-0.06)], two or more [(0.08 (0.06-0.10)], three or more [(0.08 (0.06-0.09)] and four or more [(0.06 (0.05-0.07)] micronutrients.

Greater variety in fruit and vegetable intake was associated with better nutrient adequacy, diet quality and healthier lifestyle in an elderly Mediterranean population.

Denervation of renal sympathetic nerves (RDN) is an invasive endovascular procedure introduced as an antihypertensive treatment with a potential beneficial effect on insulin resistance (IR). We have previously demonstrated a reduction in blood pressure (BP) six months after RDN, but severe hepatic and peripheral IR, assessed by glucose tracer and two step hyperinsulinemic-euglycemic clamp (HEC), did not improve. The aim of the current study was to evaluate IR and adipokines profiles in relation to BP and arterial stiffness changes two years after RDN.

In 20 non-diabetic patients with true treatment-resistant hypertension, ambulatory and office BP were measured after witnessed intake of medications prior to, six and 24 months after RDN. Arterial stiffness index (AASI) was calculated from ambulatory BP. Insulin sensitivity (IS) was assessed using an oral glucose tolerance test (OGTT), the Homeostasis Model Assessment (HOMA-IR), HOMA-Adiponectin Model Assessment (HOMA-AD), the Quantitative Insulin Sensitivittion of a beneficial metabolic effect of RDN in patients with treatment resistant hypertension.
IR, adiponectin and leptin did not improve two years after RDN. There was no correlation between baseline IS and BP response. Our study does not support the notion of a beneficial metabolic effect of RDN in patients with treatment resistant hypertension.
The aim of this paper was to investigate and compare the effects of two iso-energetic hypo-caloric ketogenic hyper-ketonemic and non-ketogenic low carbohydrate high fat high cholesterol diets on body-composition, muscle strength and hormonal profile in experienced resistance-trained middle-aged men.

Twenty non-competitive experienced resistance-trained middle-aged men were on the supervised calorie maintenance western diet and resistance-training regimen for 4 weeks and then divided into ketogenic and non-ketogenic groups for 8 weeks period. Keto bodies (β-hydroxybutyrate) levels were measured weekly, testosterone and insulin biweekly, strength and body-composition monthly, lipid profile and blood sugar level at the beginning and at the end of the study.

Both groups lost a similar amount of lean body mass and fat tissue (from F=248.665, p<0.001 to F=21.943, p=0.001), but preserved maximal upper and lower body strength (from F=1.772, p=0.238 to F=0.595, p=0.577). Basal testosterone and free testosterone increased (from F=37.267, p=0.001 to F=16.261, p=0.005) and insulin levels decreased significantly in both groups (F=27.609, p=0.001; F=54.256, p<0.001, respectively). No differences in lipid profile and blood sugar level were found (from F=4.174, p=0.058, to F=0.065, p=0.802).

Ketogenic diet with sustained hyper-ketonemia above 1mol/l has the same impact as low carbohydrate non-ketogenic diet on muscle strength, body-composition, and hormonal and lipid profile in hypo-caloric dietary conditions in strength-trained middle-aged men.

In a placebo controlled study we sought to determine if a four-weeks tryptophan-enriched diet is able to improve age-related depression or social cognitive impairment, depending on polymorphisms located in the promoter region of Solute Carrier Family 6 Member 4 (SLC6A4), also known as serotonin transporter (SERT1) gene.

91 young volunteers (age 21±2yrs) and 127 above 50 years old (58±6yrs) healthy volunteers completed the study. selleck chemicals llc Participants from the placebo and tryptophan group followed the same protocol. Before starting the study blood samples, to measure serotonin-transporter-linked polymorphic region (5-HTTLPR) and rs25531 polymorphisms, were collected. In addition, before and after completing the study urine samples (to measure 5-hydroxyindolacetic acid (5-HIAA) were taken, while psychological questionnaires (to assess depression and social cognition levels), and a one week dietary record (to calculate the tryptophan (TRP) intake) were assessed.

The triallelic approach of SLC6A4 showed that in S'S´ subjects there was a positive correlation between TRP intake and 5-HIAA levels. Age of participants, SLC6A4 genotype, and experimental condition were important factors contributing to the outcome of depression and social cognition.

5-HTTLPR and rs25531 polymorphisms play a key role in the response to the TRP- based nutritional intervention, improving only age-related depressive symptoms and empathy in S'S´ subjects who have a higher risk to show signs of depression during their lifetime.

Oxylipins (OXLs) are bioactive lipid metabolites derived from polyunsaturated fatty acids (PUFAs) which act as signaling molecules and are involved in inflammatory processes such as those that occur in obesity. On the other hand, gut microbiota plays an essential role in regulating inflammatory responses. However, little is known about the potential impact of gut bacteria on OXLs metabolism. Thus, the objective of this study was to investigate the effect of gut microbiota dysbiosis on plasma oxylipins profile in healthy and diet-induced obese animals.

Eight-week-old male Wistar rats were fed with either a standard or cafeteria diet (CAF) for 5 weeks and administered an antibiotic cocktail (ABX) in the drinking water (Ampicillin 1g/ml, Vancomycin 0.5g/ml, Imipenem 0.25g/ml) for the last 2 weeks in order to induce gut microbiota dysbiosis. Metabolomics analysis of OXLs in plasma was performed by HPLC-MS analysis. No antibiotic treated animals were included as controls.

Plasma OXLs profile was significantly altered due to both CAF feeding and ABX administration.
