Dietary pro-oxidant therapy by a vitamin #K precursor targets PI 3-kinase VPS34 function

In light of emerging evidence that antioxidants can have cancer-promoting effects, Swamynathan et al. tested potential pro-oxidant interventions (see the Perspective by Pannia and Dowling). In particular, the authors focused on menadione sodium bisulfite, a water-soluble precursor of vitamin K. As the authors anticipated, this menadione derivative suppressed prostate cancer growth. The researchers then examined… Continue reading Dietary pro-oxidant therapy by a vitamin #K precursor targets PI 3-kinase VPS34 function

Modifiers of the Effects of Vitamin #D Supplementation on #Cardiometabolic Risk Factors: A Systematic Review and Meta-Analysis

The inconsistent findings concerning the effects of vitamin D supplementation on cardiometabolic risk factors and the large heterogeneity in the published literature call for further research to identify sources of heterogeneity and potential effect modifiers. We performed a meta-analysis of randomized controlled trials (RCTs) published until March 2024 that reported estimates for the effects of… Continue reading Modifiers of the Effects of Vitamin #D Supplementation on #Cardiometabolic Risk Factors: A Systematic Review and Meta-Analysis

ω-3 #PUFA for Secondary Prevention of White Matter Lesions and Neuronal Integrity Breakdown in Older AdultsA Randomized Clinical Trial

Importance  Older adults with lower intake and tissue levels of long-chain ω-3 polyunsaturated fatty acids (PUFAs) eicosapentaenoic acid (EPA; 20:5) and docosahexaenoic acid (DHA; 22:6) have more brain white matter lesions (WMLs), an association suggesting that small-vessel ischemic disease, a major contributor to the development of dementia, including Alzheimer disease, may be preventable through ω-3 treatment.Objective  To… Continue reading ω-3 #PUFA for Secondary Prevention of White Matter Lesions and Neuronal Integrity Breakdown in Older AdultsA Randomized Clinical Trial

The association between dietary vitamin #B1 intake and #constipation: a population-based study

BackgroundNumerous researches have indicated a correlation between the intake of dietary micronutrients and the occurrence of constipation. Nevertheless, the correlation between constipation and vitamin B1 remains uninvestigated. The main aim of this research was to examine the association between chronic constipation and the consumption of vitamin B1 in the diet among adult participants of the… Continue reading The association between dietary vitamin #B1 intake and #constipation: a population-based study

#Omega-3 supplementation reduces aggressive #behavior: A meta-analytic review of randomized controlled trials

AbstractThere is increasing interest in the use of omega-3 supplements to reduce aggressive behavior. This meta-analysis summarizes findings from 29 RCTs (randomized controlled trials) on omega-3 supplementation to reduce aggression, yielding 35 independent samples with a total of 3918 participants. Three analyses were conducted where the unit of analysis was independent samples, independent studies, and… Continue reading #Omega-3 supplementation reduces aggressive #behavior: A meta-analytic review of randomized controlled trials

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

A terminal metabolite of niacin promotes vascular inflammation and contributes to #cardiovascular disease risk

Despite intensive preventive cardiovascular disease (CVD) efforts, substantial residual CVD risk remains even for individuals receiving all guideline-recommended interventions. Niacin is an essential micronutrient fortified in food staples, but its role in CVD is not well understood. In this study, untargeted metabolomics analysis of fasting plasma from stable cardiac patients in a prospective discovery cohort… Continue reading A terminal metabolite of niacin promotes vascular inflammation and contributes to #cardiovascular disease risk

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
