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...

The aim of this study was to examine usual daily micronutrient intake of Chinese children based on data from the 2011 China Health and Nutrition Survey. We analyzed data from 4 to 17-year-old participants, who provided dietary data on three consecutive days combined with the household weighing method in 2011. Usual daily intake of each nutrient was estimated using a mixed effects model based on the China Food Composition published in 2009. The means, medians and percentages below Estimated Average Requirements (EAR) were reported for selected micronutrients, including calcium, sodium, potassium, iron, zinc, selenium, vitamin A, thiamine, riboflavin and vitamin C...

The effect of skipping breakfast on health, especially in adults, remains a controversial topic. A secondary data analysis was conducted to examine associations between breakfast eating patterns and weight loss, nutrient intake, and metabolic parameters among participants with metabolic syndrome (MetS) (n = 240). Three randomly selected 24-h dietary recalls were collected from each participant at baseline and at the one-year visit. Skipped breakfast was seen in 32.9% at baseline and in 17.4% at the one-year visit, respectively...

REVIEW
Abdoulaye Bâ
Accumulating evidence has shown that binge-type alcohol intake in mothers interferes with thiamine deficiency (TD) to promote the fetal alcohol syndrome (FAS). Developmental alcohol or TD exposures act either synergistically or separately to reproduce FAS features e.g. intrauterine growth retardation and related microcephaly characterized by extensive cellular death induced by one another neurotoxicant. However molecular and cellular mechanisms underlying apoptosis in both alcohol and TD toxicities are unknown...

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...

Wernicke's encephalopathy (WE) is an unexpected common neurological disorder caused by thiamine deficiency often due to alcohol abuse, but WE-not alcohol related is also frequent. A prolonged reduction of food intake can cause WE. This condition can arise in depression disorders, especially in the early stages of these psychiatric syndromes. WE is characterized by the triad of signs: ataxia, ocular dysfunctions and confusional state. However, they rarely appear together and this makes the diagnosis particularly difficult, especially when there is not a history of alcohol abuse...

Biotin-thiamine responsive basal ganglia disease is an inborn error of metabolism caused by mutations in SLC19A3, encoding a transporter of thiamine across the plasma membrane. We report a novel mutation identified in the homozygous state in a patient with typical brain MRI changes. In addition, this patient had markedly elevated CSF pyruvate, a low lactate-to-pyruvate molar ratio, and an abnormal pyruvate peak at 2.4 ppm on brain magnetic resonance spectroscopy. Using aggregated exome sequencing data, we calculate the carrier frequency of mutations in SLC19A3 as 1 in 232 individuals in the general population, for an estimated prevalence of the disease of approximately 1 in 215,000 individuals...

We report a rare case of non-alcoholic Wernicke encephalopathy (WE) with polyneuropathy. A 24-year-old woman who had recently served a 4-month prison sentence and underwent a short period of dieting manifested slow response, weakness, language disorder and amnesia. Brain magnetic resonance imaging (MRI) revealed typical lesions of WE. Examination of nerve conduction velocity revealed sensory-motor axonal polyneuropathy. The patient was immediately treated with thiamine. Neurological symptoms were alleviated in a few days and abnormal signals were markedly decreased in a follow-up MRI 1 week later...

Jorge C Kattah
PURPOSE: The first aim of this review is to summarize recent ocular motor signs in pre-encephalopathy patients with nutritional deficiency at risk of thiamine deficiency. Timely recognition of thiamine depletion in these patients, who may have a normal brain MRI, could lead to appropriate management and prevention of Wernicke's encephalopathy (WE) with full recovery. The second aim is to incorporate recent diagnostic testing on the revised WE diagnostic criteria and the identification of patients who may show slow, partial, or no response to treatment...

Analysis of 49 strains of Fusarium langsethiae originating from northern Europe (Russia, Finland, Sweden, UK, Norway, and Latvia) revealed the presence of spontaneous auxotrophic mutants that reflect natural intraspecific diversity. Our investigations detected that 49.0% of F. langsethiae strains were auxotrophic mutants for biotin, and 8.2% of the strains required thiamine as a growth factor. They failed to grow on vitamin-free media. For both prototrophic and auxotrophic strains, no growth defect was observed in rich organic media...

Micronutrient deficiencies contribute to many age-related disorders, although initial effects may be mild and easily missed. For example, B vitamin deficiency may result in mild cognitive decline, thiamine deficiency can contribute to development of type 2 diabetes and lack of vitamin D changes immune function.

BACKGROUND: Concentrated breeding effort to produce various body structures and behaviors of dogs to suit human demand has inadvertently produced unwanted traits and diseases that accompany the morphological and behavioral phenotypes. We explored the relationship between pelvic conformation and canine hip dysplasia (HD) because purebred dogs which are predisposed, or not, to HD share common morphologic features, respectively. Thirteen unique bilateral anatomical features of the pelvis were measured on 392 dogs of 51 breeds and 95 mixed breed dogs...

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...

A 38-year-old woman was admitted in a psychiatric hospital because of memory disorders. Dry beriberi and Korsakoff's syndrome, as a late neuropsychiatric manifestation of Wernicke's encephalopathy, were established. The beriberi symptoms decreased slowly, but the patient's memory impairments persisted. These clinical features were caused by a thiamine deficiency. Gastric bypass surgery is associated with an increased risk of thiamine deficiency. Excessive alcohol consumption and poor compliance with vitamin deficiency treatment both contributed to the rapid onset of these disorders...

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...

The effects of chronic EtOH consumption, associated or not with thiamine deficiency (TD), on cognitive impairment, oxidative damage, and β-amyloid (Aβ) peptide accumulation in the brain were investigated in male C57BL/6 mice. We established an alcoholic mouse model by feeding an EtOH liquid diet, a TD mouse model by feeding a thiamine-depleted liquid diet, and an EtOH treatment associated with TD mouse model by feeding a thiamine-depleted EtOH liquid diet for 7 weeks. The learning and memory functions of the mice were detected through the Y-maze test...
