REVIEW
Michael A Via, Jeffrey I Mechanick
PURPOSE OF REVIEW: The continued success of bariatric surgery to treat obesity and obesity-associated metabolic conditions creates a need for a strong understanding of clinical nutrition both before and after these procedures. RECENT FINDINGS: Surgically induced alteration of gastrointestinal physiology can affect the nutrition of individuals, especially among those who have undergone malabsorptive procedures. While uncommon, a subset of patients may develop protein-calorie malnutrition...

INTRODUCTION: The lifestyle product 'Eezup!' appeared on the German market and promised to normalize energy metabolism. Among vitamins (B1, B2, B6, C, E and zinc), rice protein and fructose the addition of alcohol dehydrogenase and catalase enzymes is a novel approach. The product was advertised as capable of boosting the rate of alcohol elimination. METHODS: Seventeen subjects (11 men, 6 women, 19-58 years old), participated in a two-way crossover drinking study...

BACKGROUND: Thiamine (vitamin B1) is an essential cofactor responsible for the breakdown of glucose, and its deficiency is associated with Wernicke encephalopathy (WE). There is a lack of evidence from systematic studies on the optimal dosing of thiamine for WE. Objectives: The primary objective was to describe the prescribing patterns for IV thiamine in adult patients admitted to a large teaching hospital. The secondary objective was to evaluate the clinical resolution of WE symptoms (confusion, ataxia, and/or ocular motor abnormalities) in relation to the dose of IV thiamine prescribed...

Insects with restricted diets rely on obligate microbes to fulfil nutritional requirements essential for biological function. Tsetse flies, vectors of African trypanosome parasites, feed exclusively on vertebrate blood and harbour the obligate endosymbiont Wigglesworthia glossinidia. Without Wigglesworthia, tsetse are unable to reproduce. These symbionts are sheltered within specialized cells (bacteriocytes) that form the midgut-associated bacteriome organ. To decipher the core functions of this symbiosis essential for tsetse's survival, we performed dual-RNA-seq analysis of the bacteriome, coupled with metabolomic analysis of bacteriome and haemolymph collected from normal and symbiont-cured (sterile) females...

Creutzfeldt-Jakob disease (CJD) has a significant degree of clinical heterogeneity that is especially found in the features at onset. Here we present a patient with the sporadic form of CJD mimicking Wernicke encephalopathy. We first treated him with a high dose of thiamine; however, the vitamin B1 levels proved to be normal, which ruled out Wernicke encephalopathy. Meanwhile, his clinical condition progressively worsened and he developed a rapidly progressive cognitive disorder, mutism and myoclonus of the muscles...

REVIEW

Over the last five decades, many methods to analyze thiamine (vitamin B1) and its phosphorylated forms in urine, whole blood, serum, plasma and erythrocytes have been proposed. Some of the methods are presently used in routine practice, but analytical problems regarding reproducibility, standardization, lack of automation, time consuming procedures for pretreatment and analysis are often discussed. With modern approaches to bioanalysis in clinical research of vitamins, whole processes can be automated, making analysis less time consuming, with reduced consumption of solvents and samples...

Processed and prepackaged space food is the main source of nutrition for crew aboard the International Space Station, and likely will continue to be the main source of nutrition for future exploration missions. However, very little information is available on the nutritional stability of space foods. To better understand their nutritional stability, 24 micronutrients were measured in 109 space foods stored over 3 years at room temperature. Our analysis indicated that potassium, calcium, vitamin D, and vitamin K concentrations in the food may not be adequate to meet the recommended daily intake requirements even before storage...

To calculate micronutrient adequacy among infants and toddlers and to determine the contribution of dietary supplements to this adequacy, micronutrient intake was assessed using two nonconsecutive 24-hour recalls in a sample of 296 infants aged 0-24 months. Micronutrient intake was calculated from foods and beverages and from supplements and compared between nonusers and users of supplements. Percentages of children below the Dietary Reference Intake (DRI) and above the tolerable upper limit intake (UL) were also compared between groups...

The present study seeks to identify the nutritional risk factors involved in the development of neuropathies induced by chemotherapeutic treatments. Unlike the gastrointestinal or hematological adverse effects of chemotherapy there is no protective treatment strategy for polyneuropathy. The aim of this study was to find possible deficiencies in nutritional factors, which can be used for supplementation in the future for prevention of chemotherapy-induced neuropathy development. We analyzed 70 patients undergoing paclitaxel chemotherapy and evaluated the risk factors involved in chemotherapy-induced peripheral neuropathy (CIPN)...

PURPOSE: There are theoretical and empirical reasons to consider a potential role for copper metabolism in the brain in how it could influence stuttering. However, a link between stuttering and dietary intake has never been researched in a systematic way. This pilot study therefore aimed to explore a possible association between ingested amounts of copper and thiamine (vitamin B1) with stuttering frequency using a double blind cross-over longitudinal paradigm. METHODS: 19 adults who stutter between 20 and 51 years old filled out an online survey for 9 consecutive weeks...

The increasing prevalence of morbid obesity in Germany is associated with an increasing number of metabolic surgical interventions. Short-term surgical and long-term metabolic complications such as nutrient deficiencies can be considered as the main risks of metabolic surgery with its malabsorptive but also restrictive procedures. The aim of this review is to characterize the most relevant metabolic complications specific for the various bariatric procedures, which, subsequently, require a permanent surveillance and supplementation, respectively...

Iga Rybicka, Anna Gliszczynska-Swiglo
Gluten-free (GF) products are those with a natural absence or acceptable level (<20 mg/kg) of gluten. They should be a part of a diet for people with gluten-related disorders, like celiac disease. Recently the popularity of a gluten-free diet (GFD) has risen extremely, because a lot of healthy individuals exclude gluten from their menus. According to the literature data on nutritional deficiencies in the GFD, this trend seems to be risky. This paper describes the nutritional value of 14 flours from different GF raw materials from the aspect of B-group vitamin content (B1, B2, B3, B6)...
