Salt Substitution and Recurrent #Stroke and DeathA Randomized Clinical Trial

Question  Does the use of a reduced-sodium, added-potassium salt substitute vs regular salt decrease the risk of stroke recurrence and death in patients with a history of stroke?Findings  In this prespecified subgroup analysis of the Salt Substitute and Stroke Study (SSaSS) trial involving 15 249 patients with stroke, the use of a salt substitute led… Continue reading Salt Substitution and Recurrent #Stroke and DeathA Randomized Clinical Trial

Individual and additive effects of vitamin #D, #omega-3 and #exercise on DNA methylation clocks of biological aging in older adults from the DO-HEALTH trial

While observational studies and small pilot trials suggest that vitamin D, omega-3 and exercise may slow biological aging, larger clinical trials testing these treatments individually or in combination are lacking. Here, we report the results of a post hoc analysis among 777 participants of the DO-HEALTH trial on the effect of vitamin D (2,000 IU per… Continue reading Individual and additive effects of vitamin #D, #omega-3 and #exercise on DNA methylation clocks of biological aging in older adults from the DO-HEALTH trial

Dietary #fructose enhances #tumour growth indirectly via interorgan lipid transfer

Fructose consumption has increased considerably over the past five decades, largely due to the widespread use of high-fructose corn syrup as a sweetener1. It has been proposed that fructose promotes the growth of some tumours directly by serving as a fuel2,3. Here we show that fructose supplementation enhances tumour growth in animal models of melanoma,… Continue reading Dietary #fructose enhances #tumour growth indirectly via interorgan lipid transfer

Blood #Pressure Decreases in #Overweight Elderly Individuals on Vitamin #D: A Randomized Trial

AbstractContextEvidence for a beneficial role of vitamin D on blood pressure (BP) outcomes is inconclusive.ObjectiveThis work aimed to investigate the effect of 2 doses of cholecalciferol (vitamin D3) supplementation coadministered with calcium on systolic blood pressure (SBP) and diastolic blood pressure (DBP).MethodsExploratory analyses were conducted from a 1-year, multicenter, double-blind, randomized controlled trial (RCT). Total… Continue reading Blood #Pressure Decreases in #Overweight Elderly Individuals on Vitamin #D: A Randomized Trial

Associations of plasma omega-6 and omega-3 #fatty acids with overall and 19 site-specific #cancers: A population-based cohort study in UK Biobank

AbstractPrevious epidemiological studies on the associations between polyunsaturated fatty acids (PUFAs) and cancer incidence have been inconsistent. We investigated the associations of plasma omega-3 and omega-6 PUFAs with the incidence of overall and 19 site-specific cancers in a large prospective cohort. 253,138 eligible UK Biobank participants were included in our study. With a mean follow-up… Continue reading Associations of plasma omega-6 and omega-3 #fatty acids with overall and 19 site-specific #cancers: A population-based cohort study in UK Biobank

Skewed epithelial cell differentiation and premature aging of the thymus in the absence of vitamin #D signaling

Central tolerance of thymocytes to self-antigen depends on the medullary thymic epithelial cell (mTEC) transcription factor autoimmune regulator (Aire), which drives tissue-restricted antigen (TRA) gene expression. Vitamin D signaling regulates Aire and TRA expression in mTECs, providing a basis for links between vitamin D deficiency and autoimmunity. We find that mice lacking Cyp27b1, which cannot… Continue reading Skewed epithelial cell differentiation and premature aging of the thymus in the absence of vitamin #D signaling

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
