BACKGROUND: Burning mouth syndrome (BMS) is a disorder characterized by chronic mouth pain in the absence of objective clinical abnormalities. Vitamin or mineral deficiencies may have a role in BMS, but data regarding the prevalence and relevance of hematinic deficiencies are conflicting. We aimed to determine the frequency of specific laboratory abnormalities in patients with BMS. METHODS: We retrospectively reviewed the results of screening blood tests in patients with BMS at our institution between January 2003 and December 2013...

BACKGROUND: Thiamine has a crucial role in energy production, and consequently thiamine deficiency (TD) has been associated with cardiac failure, neurological disorders, oxidative stress (lactic acidosis and sepsis) and refeeding syndrome (RFS). This review aims to explore analytical methodologies of thiamine compound quantification and highlight similarities, variances and limitations of current techniques and how they may be relevant to patients. CONTENT: An electronic search of Medline, PubMed and Embase databases for original articles published in peer-reviewed journals was conducted...

Euglena gracilis Z requires vitamins B1 and B12 for growth. It takes up and accumulates large amounts of these exogenous vitamins through energy-dependent active transport systems. Except for these essential vitamins, E. gracilis Z has the ability to synthesize all human vitamins. Euglena synthesizes high levels of antioxidant vitamins such as vitamins C and E, and, thus, are used as nutritional supplements for humans and domestic animals. Methods to effectively produce vitamins in Euglena have been investigated...

The purpose of this work was to understand low recoveries of thiamine (vitamin B1) when extracted from cocoa-containing beverage powders fortified with water-soluble vitamin B1, and to develop and validate a new procedure to improve these results. Based on the literature, previous trials have focused on two main factors: pH value prior to paper filtration and the need for solid-phase extraction (SPE) clean up. We demonstrate that by following European Standard EN 14122, recovery of thiamine in cocoa-containing beverage powders is low and dependent on the test portion (86 and 72% for 0...

Type 2 diabetes mellitus (T2DM) is a major public health challenge that affects countries across the world. The use of pharmacological therapy is often limited in some patients due to a loss of effect over time or development of adverse effects such as weight gain or hypoglycaemia. This has prompted searches into the role of non-pharmacological therapies in T2DM. The availability and use of vitamin supplements in developed countries have increased significantly and there is evidence that certain vitamins may have roles in the management of T2DM...

Insects with restricted diets rely on symbiotic bacteria to provide essential metabolites missing in their diet. The blood-sucking lice are obligate, host-specific parasites of mammals and are themselves host to symbiotic bacteria. In human lice, these bacterial symbionts supply the lice with B-vitamins. Here we sequenced the genomes of symbiotic and heritable bacterial of human, chimpanzee, gorilla, and monkey lice and used phylogenomics to investigate their evolutionary relationships. We find that these symbionts have a phylogenetic history reflecting the louse phylogeny, a finding contrary to previous reports of symbiont replacement...

The aim of this study was to investigate the relationship between dietary habits and hip bone health in community-dwelling individuals with chronic stroke. The usual dietary intake of 94 individuals with chronic stroke (30 women, mean age: 59.0 years) was assessed by a 3-day food record within a single week. Dual-energy X-ray absorptiometry was used to measure bone mineral density (BMD) at both hips. The results showed that low hip bone mass was found in 59 and 50 of the participants on the affected and unaffected side, respectively...

Thiamine (vitamin B1) is essential to the health of all living organisms and deficiency has long been associated with diseases in animals such as fish, birds, alligators, and domesticated ruminant mammals. Thiamine is also implicated in several human diseases including Alzheimer's, diabetes, dementia, depression and, most notably, Wernicke-Korsakoff syndrome and Beriberi disease. Yet, highly sensitive and specific detection of thiamine remains an analytical challenge, as pM to nm levels of thiamine need to be detected in environmental and human samples, respectively, various phosphorylated variants need to be discriminated, and rapid on-site detection would be highly desirable...

BACKGROUND: Optimizing postoperative patient outcomes and nutritional status begins preoperatively. Patients should be educated before and after weight loss surgery (WLS) on the expected nutrient deficiencies associated with alterations in physiology. Although surgery can exacerbate preexisting nutrient deficiencies, preoperative screening for vitamin deficiencies has not been the norm in the majority of WLS practices. Screening is important because it is common for patients who present for WLS to have at least 1 vitamin or mineral deficiency preoperatively...

BACKGROUND & AIM: There is increasing evidence that the plasma concentration of vitamin D, carotenoids, zinc and selenium are associated with the magnitude of the systemic inflammatory response. In order to examine whether other vitamins may be affected and whether red cell concentrations are less affected by systemic inflammation the aim of the present study was to examine the effect of the systemic inflammatory response on red cell measurements of vitamins B1, B2 and B6, and plasma concentration of vitamin C and E in a large cohort of patients referred for a nutritional screen...

Wernicke-Korsakoff syndrome is a potentially debilitating and fatal condition that is caused by thiamine (vitamin B1) deficiency in the brain. It can be treated effectively or prevented completely; however, the condition is often undiagnosed and inadequately managed. Wernicke-Korsakoff syndrome is commonly considered to be specific to individuals who misuse alcohol; however, there are many other predisposing factors and causes associated with the condition. This article aims to raise awareness of Wernicke-Korsakoff syndrome, to enable nurses in all practice settings to recognise the signs, symptoms and risk factors associated with the condition and be informed about available treatments...

Thiamin diphosphate (TPP, vitamin B1) is an essential coenzyme present in all organisms. Animals obtain TPP from their diets, but plants synthesize TPP de novo. We isolated and characterized an Arabidopsis pale green1 (pale1) mutant that contained higher concentrations of thiamin monophosphate (TMP) and less thiamin and TPP than the wild type. Supplementation with thiamin, but not the thiazole and pyrimidine precursors, rescued the mutant phenotype, indicating that the pale1 mutant is a thiamin-deficient mutant...

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...

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...
