Cost‐Effectiveness of Ferritin Screening Thresholds for Iron Deficiency in Reproductive‐Age Women

American Journal of Hematology, EarlyView.
ABSTRACT Iron deficiency (ID) is a top five leading cause of disability‐adjusted life‐years in women of reproductive age around the world. Despite its enormous health burden, no screening guidelines exist for the detection and treatment of ID in women of reproductive age.

Phenotypical Characterization of Gastroenterological and Metabolic Manifestations in Patients With Williams–Beuren Syndrome

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Gastrointestinal (GI) symptoms are common in patients with Williams–Beuren syndrome (WBS), but their prevalence and possible causes are not yet fully known. This study assessed GI symptoms' prevalence and their possible origin by performing a predefined set of tests in adult WBS patients.

The relationship between exacerbated diabetic peripheral neuropathy and metformin treatment in type 2 diabetes mellitus

Scientific Reports, 2021
Metformin-treated diabetics (MTD) showed a decrease in cobalamin, a rise in homocysteine, and methylmalonic acid, leading to accentuated diabetic peripheral neuropathy (DPN). This study aimed to determine whether or not metformin is a risk factor for DPN.

Vitamin B12 Levels Association with Functional and Structural Biomarkers of Central Nervous System Injury in Older Adults

Annals of Neurology, EarlyView.
At low levels of B12, specifically when bound to transcobalamin for cellular uptake, evidence of slower conductivity in the brain could point toward impaired myelin. At high levels of B12, specifically when bound to the biologically inert transport protein haptocorrin, biomarkers of neurodegeneration appear in the serum, indicating neuroaxonal injury ...

A dodecylamine derivative of cyanocobalamin potently inhibits the activities of cobalamin-dependent methylmalonyl-CoA mutase and methionine synthase of Caenorhabditis elegans

FEBS Open Bio, 2014
In this study, we showed that cyanocobalamin dodecylamine, a ribose 5′-carbamate derivative of cyanocobalamin, was absorbed and accumulated to significant levels by Caenorhabditis elegans and was not further metabolized.

Cobalamin coenzyme forms are not likely to be superior to cyano‐ and hydroxyl‐cobalamin in prevention or treatment of cobalamin deficiency [PDF]

Molecular Nutrition & Food Research, 2015
Methylcobalamin (MeCbl) and adenosylcobalamin (AdoCbl) are coenzymes for methionine synthase and methylmalonyl‐CoA mutase, respectively. Hydroxylcobalamin (HOCbl) and cyanocobalamin (CNCbl) are frequently used for supplementation. MeCbl and AdoCbl have recently emerged as alternative forms in supplements. In the light of metabolic transformation of Cbl
