CONTEXT: Bariatric surgery has beneficial effects on obesity and associated comorbidities such as glycaemic control in type 2 diabetes, dyslipidaemia, hypertension, and renal and hepatic function. Nevertheless, this surgery is not free of complications and possible side effects due to restrictive and/or malabsorptive related components. CASE DESCRIPTION: We report the case of a 60-year-old woman whose past medical history included morbid obesity, hypertension and Scopinaro biliopancreatic diversion (BPD) with duodenal switch in 1998...

PURPOSE: Observational studies indicate a positive association between circulating 25-hydroxyvitamin D (25OHD) and testosterone (T) concentrations. Because low 25OHD concentrations and T deficiency are considered to be a generalized phenomenon in patients with advanced heart failure (HF), we aimed to investigate whether vitamin D supplementation has beneficial effects on T indices in these patients. METHODS: In a pre-specified secondary analysis of the EVITA (effect of vitamin D on mortality in heart failure) randomized controlled trial, we analyzed in male subjects with 25OHD concentrations < 75 nmol/L the effect of a daily vitamin D3 supplement of 4000 IU for 3 years (n = 71) vs...

Background: Epidemiologic and in vitro studies suggest independent linkages between poor folate and/or vitamin B-12 nutrition, genomic human papillomavirus (HPV) type 16 viral integration, and cancer. However, there is no direct evidence in vivo to support the causative role of poor folate nutrition in HPV16 integration into the cellular genome. Objective: We tested the hypothesis that folate deficiency enables the integration of HPV16 into the genome of HPV16-harboring keratinocytes, and could thereby influence earlier transformation of these cells to cancer in an animal model...

Background: Formate is produced in mitochondria via the catabolism of serine, glycine, dimethylglycine, and sarcosine. Formate produced by mitochondria may be incorporated into the cytosolic folate pool where it can be used for important biosynthetic reactions. Previous studies from our lab have shown that cobalamin deficiency results in increased plasma formate concentrations. Objective: Our goal was to determine the basis for elevated formate in vitamin B-12 deficiency...

We report a case of a 46-year-old woman with a history of autoimmune atrophic gastritis and recurrent erythema nodosum (EN). Laboratory results showed iron-deficiency anaemia, positive antiparietal cell antibodies and marginal deficiency of vitamin B12. Although EN was refractory to general measures (rest and non-steroidal anti-inflammatory drugs) and corticosteroid therapy, it was successfully treated with vitamin B12 supplementation.

Although vitamin D is critical to calcium/phosphorus homeostasis, bone formation and remodeling, there is evolution-based variation between species in vitamin D metabolism and susceptibility to rickets and osteomalacia. Most herbivores produce vitamin D3 in response to sunlight, but dogs and cats have generally lost the ability as carnivore diets are rich in vitamin D. Nutritional deficiencies and/or poor exposure to sunlight can induce rickets in birds, swine, cattle and sheep, but horses are less susceptible as they have evolved a calcium homeostasis that is quite different than other animals...

BACKGROUND: Vitamin B12 deficiency is common, and the incidence increases with age. Most people with vitamin B12 deficiency are treated in primary care with intramuscular (IM) vitamin B12 . Doctors may not be prescribing oral vitamin B12 formulations because they may be unaware of this option or have concerns regarding its effectiveness. OBJECTIVES: To assess the effects of oral vitamin B12 versus intramuscular vitamin B12 for vitamin B12 deficiency. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, and LILACS, as well as the WHO ICTRP and ClinicalTrials...

Information is limited on the current vitamin B12 status of South Koreans, including the results of biochemical indices. The objective of this study was to assess vitamin B12 status with vitamin B12 intake, major food sources, and plasma vitamin B12 concentration in Korean adults. We hypothesized that vitamin B12 intake and status would be different between sex and age groups. Three consecutive 24-hour recalls and fasting blood samples were obtained from healthy 20- to 64-year-old adults (N=141). The dietary vitamin B12 intake of the men (10...

BACKGROUND: Abetalipoproteinemia and homozygous hypobetalipoproteinemia are classical Mendelian autosomal recessive and co-dominant conditions, respectively, which are phenotypically similar and are usually caused by bi-allelic mutations in MTTP and APOB genes, respectively. Instances of more complex patterns of genomic variants resulting in this distinct phenotype have not been reported. METHODS: A 43 year-old male had a longstanding severe deficiency of apolipoprotein (apo) B-containing lipoproteins and circulating fat soluble vitamins consistent with either abetalipoproteinemia or homozygous familial hypobetalipoproteinemia (FHBL)...
