INTRODUCTION: The aim of this study was to assess the incidence, clinical presentation, and outcomes of neurologic disorders secondary to vitamin B deficiencies following bariatric surgery. METHODS: Patients at a single academic institution who underwent bariatric surgery and developed neurologic complications secondary to low levels of vitamins B1, B2, B6, and B12 between the years 2004 and 2015 were studied. RESULTS: In total, 47 (0.7%) bariatric surgical patients (Roux-en-Y gastric bypass n = 36, sleeve gastrectomy n = 9, and duodenal switch n = 2) developed neurologic manifestations secondary to vitamin B deficiencies...

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: Nutritional deficiencies are common after bariatric surgery, but data are scarce after sleeve gastrectomy (SG) at long term. METHODS: We performed a prospective nutritional status evaluation before and at 2 and 5 years after SG in morbid obese patients receiving mulvitamin and mineral supplementation at a Spanish university hospital. One hundred seventy-six patients (49.3 ± 9.1 years and 46.7 ± 7.4 kg/m(2)) were evaluated; 51 of them were followed during 5 years...

We investigated the long-term implications of infantile thiamine (vitamin B1) deficiency on motor function in preschoolers who had been fed during the first 2 years of life with a faulty milk substitute. In this retrospective cohort study, 39 children aged 5-6 years who had been exposed to a thiamine-deficient formula during infancy were compared with 30 age-matched healthy children with unremarkable infant nutritional history. The motor function of the participants was evaluated with The Movement Assessment Battery for Children (M-ABC) and the Zuk Assessment...

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...

BACKGROUND/OBJECTIVES: Most bariatric guidelines recommend frequent lab monitoring of patients to detect nutrient and vitamin deficiencies as early as possible. The aim of this study was to optimize the cost effectiveness of the nutrient panel, by developing an algorithm, which detects nutrient deficiencies at lower costs. SUBJECTS/METHODS: In this retrospective study, 2055 patients who had undergone Laparoscopic Roux-Y Gastric Bypass (LRYGB) and Laparoscopic Sleeve Gastrectomy (LSG) surgery at Catharina Hospital Eindhoven between January 2009 and December 2013 were included...

Many wildlife populations are declining at rates higher than can be explained by known threats to biodiversity. Recently, thiamine (vitamin B1) deficiency has emerged as a possible contributing cause. Here, thiamine status was systematically investigated in three animal classes: bivalves, ray-finned fishes, and birds. Thiamine diphosphate is required as a cofactor in at least five life-sustaining enzymes that are required for basic cellular metabolism. Analysis of different phosphorylated forms of thiamine, as well as of activities and amount of holoenzyme and apoenzyme forms of thiamine-dependent enzymes, revealed episodically occurring thiamine deficiency in all three animal classes...

Roughly 1% of all weight loss surgery is performed in adolescents. There is strong evidence demonstrating significant postsurgical weight loss, improvement in quality of life, and reduction in comorbidities such as hypertension and diabetes. Reports of postoperative complications in adolescents are few because of the small sample size in most series. Despite vitamin supplementation, nutritional deficiencies requiring hospitalization occur occasionally after Roux-en-Y gastric bypass. Wernicke encephalopathy, a triad of ophthalmoplegia, ataxia, and altered mental status, is a serious consequence of thiamine (vitamin B1) deficiency...

Several cosmopolitan marine picoeukaryotic phytoplankton are B1 auxotrophs requiring exogenous vitamin B1 or precursor to survive. From genomic evidence, representatives of picoeukaryotic phytoplankton (Ostreococcus and Micromonas spp.) were predicted to use known thiazole and pyrimidine B1 precursors to meet their B1 demands, however, recent culture-based experiments could not confirm this assumption. We hypothesized these phytoplankton strains could grow on precursors alone, but required a thiazole-related precursor other the well-known and extensively tested 4-methyl-5-thiazoleethanol...

BACKGROUND & OBJECTIVES: Hepatic scavenger receptor class B1 (SR-B1), a high-density lipoprotein (HDL) receptor, is involved in the selective uptake of HDL-associated esterified cholesterol (EC), thereby regulates cholesterol homoeostasis and improves reverse cholesterol transport. Previously, we reported in euglycaemic obese rats (WNIN/Ob strain) that feeding of vitamin A-enriched diet normalized hypercholesterolaemia, possibly through hepatic SR-B1-mediated pathway. This study was aimed to test whether it would be possible to normalize hypercholesterolaemia in glucose-intolerant obese rat model (WNIN/GR/Ob) through similar mechanism by feeding identical vitamin A-enriched diet...

: Thiamine (vitamin B1) is a precursor of thiamine pyrophosphate (TPP), an essential coenzyme in the central metabolism of all living organisms. Bacterial thiamine biosynthesis and salvage genes are controlled at the RNA level by TPP-responsive riboswitches. In Archaea, TPP riboswitches are restricted to the Thermoplasmatales order. Mechanisms of transcriptional control of thiamine genes in other archaeal lineages remain unknown. Using the comparative genomics approach, we identified a novel family of transcriptional regulators (named ThiR) controlling thiamine biosynthesis and transport genes in diverse lineages in the Crenarchaeota phylum as well as in the Halobacteria and Thermococci classes of the Euryarchaeota ThiR regulators are composed of an N-terminal DNA-binding domain and a C-terminal ligand-binding domain, which is similar to the archaeal thiamine phosphate synthase ThiN...
