INTRODUCTION: Validation of food frequency questionnaires (FFQs) is recommended for accurate measurement of habitual food consumption. We assessed the relative validity of a FFQ in patients coinfected with hepatitis C virus and human immunodeficiency virus. METHODS: Each patient responded to a FFQ and three 24-hour food recalls. Pearson's correlation and weighted Kappa index analyses were performed to identify the FFQ relative validity and concordance. RESULTS: De-attenuated correlation coefficients ranged from 0...

Klaus Junghanns, Tilman Wetterling
Delirium tremens is one of the most common complications of alcohol withdrawal. It is potentially lethal and therefore should be detected as early as possible and be monitored and treated intensively. The assessment of risk factors with the Luebeck Alcohol-Withdrawal Risk Scale short form (LARS-11) can help to predict the risk of severe withdrawal adequately. As delirium cannot be differentiated from Wernicke-Encephalopathy with sufficient certainty high parenteral doses of Vitamin B1 and Magnesium orally should be given in case of any severe withdrawal symptoms...

Two separate liquid chromatography (LC)-mass spectrometry (MS) methods were developed for determination and quantification of water-soluble and fat-soluble vitamins in human tear and blood serum samples. The water-soluble vitamin method was originally developed to detect vitamins B1, B2, B3 (nicotinamide), B5, B6 (pyridoxine), B7, B9 and B12 while the fat-soluble vitamin method detected vitamins A, D3, 25(OH)D3, E and K1. These methods were then validated with tear and blood serum samples. In this data in brief article, we provide details on the two LC-MS methods development, methods sensitivity, as well as precision and accuracy for determination of vitamins in human tears and blood serum...

BACKGROUND: It has long been theorized that a relatively robust dietary intake impacts cognitive function. The aim of the study was to explore dietary intake and cognitive function in healthy Korean children and adolescents. METHODS: Three hundred and seventeen healthy children with no previous diagnosis of neurologic or psychiatric disorders were evaluated (167 girls and 150 boys with a mean age of 11.8 ± 3.3 years). Analysis indicators including food frequency questionnaires (FFQs) consisting of 76 items and neurocognitive tests including symbol digit modalities (SDMT), verbal memory, visual memory, shift attention, reasoning, and digit span (forward and backward) tests were observed and recorded...

Ethanol is an important risk factor for the occurrence of several brain disorders that depend on the amount, period and frequency of its consumption. Chronic use of ethanol often leads to the development of neurodegenerative syndromes, which cause morphological and functional impairments such as foetal alcohol syndrome in newborns exposed to ethanol during pregnancy, Wernicke-Korsakoff Syndrome and, more rarely, Marchiafava-Bignami disease (MBD). MBD is characterized by primary degeneration of the corpus callosum, without inflammation and is associated with oxidative stress and hypovitaminosis, as well as altered mental status, to mention dementia, seizures, depression and so on...

This study investigated whether athletes meet micronutrient recommendations and whether the adequacy of their intake is related to the use of dietary supplements, sport nutrition products or a combination. Micronutrient intakes of 553 Dutch (sub-) elite athletes were assessed using web-based 24-h dietary recalls with accompanying nutritional supplement questionnaires. In the majority of both users and non-users of dietary supplements, vitamin D intake was below the estimated average requirement (AR) if supplements were not included in the analysis...

Thiamine (vitamin B1) deficiency (TD) plays a major role in the etiology of Wernicke's encephalopathy (WE) which is a severe neurological disorder. TD induces selective neuronal cell death, neuroinflammation, endoplasmic reticulum (ER) stress and oxidative stress in the brain which are commonly observed in many aging-related neurodegenerative diseases, such as Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD) and progressive supranuclear palsy (PSP). However, the underlying cellular and molecular mechanisms remain unclear...

BACKGROUND: One of the major causes of mortality in the world is represented by multiple traumas. Thoracic trauma is commonly associated with polytraumas. A series of physiopathological complications follow polytraumas, leading to a significant decrease in the survival rate. As a result of injuries, significant quantities of free radicals (FR) are produced, responsible for oxidative stress (OS). To minimize the effects of OS, we recommend the administration of antioxidant substances. In this study we want to highlight statistically significant correlations between antioxidant therapy and a series of clinical variables...

BACKGROUND: The traditional duodenal switch is performed using a Roux-en-Y configuration. This procedure has proven to be the most effective procedure for long-term weight loss and co-morbidity reduction. Recently, stomach intestinal pylorus sparing surgery (SIPS) has been introduced as a simpler and potentially safer variation of the duodenal switch (DS). It is a single anastomosis end-to-side proximal duodeno-ileal bypass with a sleeve gastrectomy. In this study, we compare our outcomes between biliopancreatic diversion with duodenal switch (BPD-DS) and SIPS at 2 years...

BACKGROUND: The USDA Healthy Eating Index (HEI) is used widely to measure diet quality because it allows a number of different applications. Although several evaluations of the HEI-2010 have already been carried out, there is lack of those which focus on associations between the HEI and nutrient intakes. This study updates and expands upon previous findings on these associations. METHODS: Using German consumption data, where ∼12 million purchases from 13 131 households are recorded, HEI-2010 total and individual scores, as well as several energy and nutrient densities were calculated...

Objective: To determine the contribution of follow-up formula (FUF) to the nutrient intake of 7-24-month-old infants and young children. Methods: The cluster random sampling method and the convenience sampling method were used in combination, and geographic and economic factors were taken into consideration. Four areas of China (Beijing, Hebei, Guangxi, Guangdong) were selected, with 120 infants chosen from each of these areas (half of which were 7-12 months old, and half were 13-24 months old). A dietary survey was completed by a continuous 24-hour weighing method over two days...

Tears serve as a viable diagnostic fluid with advantages including less invasive sample to collect and less complex to prepare for analysis. Several water-soluble and fat-soluble vitamins were detected and quantified in human tears and compared with blood serum levels. Samples from 15 family pairs, each pair consisting of a four-month-old infant and one parent were analyzed; vitamin concentrations were compared between tears and blood serum for individual subjects, between infants and parents, and against self-reported dietary intakes...

Production of ethanol from xylose by recombinant Saccharomyces cerevisiae is suboptimal with slow fermentation rate, compared with that from glucose. In this study, a strain-expressing Scheffersomyces stipitis xylose reductase-xylitol dehydrogenase (XR-XDH) pathway was subjected to adaptive evolution on xylose; this approach generated populations with the significantly improved cell growth and ethanol production rate. Mutants were isolated, and the best one was used for sporulation to generate eight stable mutant strains with improved xylose fermentation ability...

Prolonged vitamin B1 (thiamine) deficiency can lead to neurological disorders such as Wernicke's encephalopathy and Wernicke-Korsakoff Syndrome (WKS) in humans. These thiamine deficiency disorders have been attributed to vascular leakage, blood-brain barrier breakdown and neuronal loss in the diencephalon and brain stem. However, endothelial dysfunction following thiamine deficiency and its relationship to the phenomenon of neurodegeneration has not been clearly elucidated. The present study sought to begin to address this issue by evaluating vascular morphology and integrity in a pyrithiamine (PT)-induced rat model of thiamine deficiency...
