Background & aims: Primary sclerosing cholangitis (#PSC ) has a variable disease course, complicating patient counseling and timing of liver transplantation. Vitamin B6 deficiency predicts reduced liver transplantation-free survival in Scandinavian PSC cohorts. Here, we aimed to validate this observation in U.S. and German PSC cohorts and expanded our analyses to include hepatic decompensation as… Continue reading Vitamin #B6 predicts poor outcomes in geographically distinct populations with primary sclerosing cholangitis

Vitamin #D3 and marine ω-3 fatty acids supplementation and leukocyte #telomere length: 4-year findings from the VITamin D and OmegA-3 TriaL (VITAL) randomized controlled trial
Limited studies suggest that vitamin D or omega 3 fatty acids (n–3 FAs) supplementation may be beneficial for telomere maintenance; however, evidence from large randomized clinical trials is lacking. We hypothesized that vitamin D or n–3 FAs supplementation reduce leukocyte telomere length (LTL) attrition over time by leveraging the VITamin D and OmegA-3 TriaL (VITAL)… Continue reading Vitamin #D3 and marine ω-3 fatty acids supplementation and leukocyte #telomere length: 4-year findings from the VITamin D and OmegA-3 TriaL (VITAL) randomized controlled trial
Subcellular #NAD+ pools are interconnected and buffered by mitochondrial NAD+
The coenzyme NAD+ is consumed by signalling enzymes, including poly-ADP-ribosyltransferases (PARPs) and sirtuins. Ageing is associated with a decrease in cellular NAD+ levels, but how cells cope with persistently decreased NAD+ concentrations is unclear. Here, we show that subcellular NAD+ pools are interconnected, with mitochondria acting as a rheostat to maintain NAD+ levels upon excessive… Continue reading Subcellular #NAD+ pools are interconnected and buffered by mitochondrial NAD+
Effect of #Ergocalciferol on β-Cell Function in New-Onset Type 1 #Diabetes A Secondary Analysis of a Randomized Clinical Trial
IntroductionApproximately 30% to 50% residual β-cell function may remain at the time of type 1 diabetes (T1D) diagnosis, and this may persist for months or years.1,2 A prolonged partial remission (PR) phase of T1D leads to improved glycemic control and decreased long-term complications.1 We previously reported1 that ergocalciferol significantly decreased circulating tumor necrosis factor (TNF)-α and temporal trends… Continue reading Effect of #Ergocalciferol on β-Cell Function in New-Onset Type 1 #Diabetes A Secondary Analysis of a Randomized Clinical Trial
Vitamin #E intake is inversely associated with #NAFLD measured by liver ultrasound transient elastography
Non-alcoholic fatty liver disease (NAFLD) is one of the most common chronic liver diseases, whose severe form is associated with oxidative stress. Vitamin E as an antioxidant has a protective potential in NAFLD. Whether dietary intake of vitamin E, supplementary vitamin E use, and total vitamin E have a preventive effect on NAFLD requires investigation.… Continue reading Vitamin #E intake is inversely associated with #NAFLD measured by liver ultrasound transient elastography
Vitamin #D and Marine n-3 #Fatty Acids for #Autoimmune Disease Prevention: Outcomes at Two Years after VITAL Trial Completion
ObjectiveIn the 5.3 year randomized, 2 x 2 factorial, double-blind, placebo-controlled VITamin D and OmegA-3 TriaL (VITAL), vitamin D supplementationreduced autoimmune disease (AD) incidence (hazard ratio [HR] 0.78, 95% confidence interval 0.61-0.99). Omega-3(n-3) fatty acid supplementation showed a statistically non-significant reduction (HR 0.85, 0.67-1.08). We aimed to confirm further AD cases arising during and after randomization and… Continue reading Vitamin #D and Marine n-3 #Fatty Acids for #Autoimmune Disease Prevention: Outcomes at Two Years after VITAL Trial Completion
Post-diagnostic #multivitamin supplement use and #colorectal cancer survival: A prospective cohort study
AbstractBackgroundUse of multivitamin supplements has been associated with lower incidence of colorectal cancer (CRC). However, its influence on CRC survival remains unknown.MethodsAmong 2424 patients with stage I–III CRC who provided detailed information about multivitamin supplements in the Nurses’ Health Study and Health Professionals Follow-up Study, the authors calculated multivariable hazard ratios (HRs) of multivitamin supplements… Continue reading Post-diagnostic #multivitamin supplement use and #colorectal cancer survival: A prospective cohort study
Dietary #Niacin Intake and Mortality Among Individuals With Nonalcoholic #Fatty #Liver Disease
Evidence regarding the effect of dietary niacin intake on the risk of mortality among patients with nonalcoholic fatty liver disease (NAFLD) is scarce.Objective To examine the association of dietary niacin intake with all-cause mortality and cardiovascular disease (CVD) mortality among individuals with NAFLD.Design, Setting, and Participants This cohort study used data from the National Health and Nutrition… Continue reading Dietary #Niacin Intake and Mortality Among Individuals With Nonalcoholic #Fatty #Liver Disease
Vitamin #B12 is a limiting factor for induced cellular plasticity and #tissue repair
Transient reprogramming by the expression of OCT4, SOX2, KLF4 and MYC (OSKM) is a therapeutic strategy for tissue regeneration and rejuvenation, but little is known about its metabolic requirements. Here we show that OSKM reprogramming in mice causes a global depletion of vitamin B12 and molecular hallmarks of methionine starvation. Supplementation with vitamin B12 increases the efficiency… Continue reading Vitamin #B12 is a limiting factor for induced cellular plasticity and #tissue repair
