IntroductionDespite the association of vitamin D deficiency with incident dementia, the role of supplementation is unclear. We prospectively explored associations between vitamin D supplementation and incident dementia in 12,388 dementia-free persons from the National Alzheimer's Coordinating Center.MethodsBaseline exposure to vitamin D was considered D+; no exposure prior to dementia onset was considered D−. Kaplan–Meier curves… Continue reading Vitamin D supplementation and incident dementia: Effects of sex, APOE, and baseline cognitive status

Micronutrient deficiencies and anaemia associated with body mass index in Australian adults: a cross-sectional study
Aim To estimate the prevalence of micronutrient deficiencies and anaemia, and their association with body mass index (BMI) categories among Australian adults. Method We analysed data from the 2011–2013 Australian Health Survey from 3539 participants aged 18 years and over (without known pregnancy) with measured weight and height, and nutrient biomarkers. To address complex sampling,… Continue reading Micronutrient deficiencies and anaemia associated with body mass index in Australian adults: a cross-sectional study
Combined use of lactoferrin and vitamin D as a preventive and therapeutic supplement for SARS-CoV-2 infection: Current evidenceCipriano M, Ruberti E, Tovani-Palone MR. Combined use of lactoferrin and vitamin D as a preventive and therapeutic supplement for SARS-CoV-2 infection: Current evidence.
Lactoferrin is a multifunctional protein that exhibits anti-inflammatory, immune regulating and anti-infective properties. One of its receptor sites is located on severe acute respiratory syndrome coronavirus 2. The binding of lactoferrin with heparin sulfate proteoglycans may prevent the first contact between the virus and host cells, thus preventing subsequent infection. Given that lactoferrin may act… Continue reading Combined use of lactoferrin and vitamin D as a preventive and therapeutic supplement for SARS-CoV-2 infection: Current evidenceCipriano M, Ruberti E, Tovani-Palone MR.

Association between vitamin D supplementation and COVID-19 infection and mortality
Vitamin D deficiency has long been associated with reduced immune function that can lead to viral infection. Several studies have shown that Vitamin D deficiency is associated with increases the risk of infection with COVID-19. However, it is unknown if treatment with Vitamin D can reduce the associated risk of COVID-19 infection, which is the… Continue reading Association between vitamin D supplementation and COVID-19 infection and mortality
Vitamin D deficiency and C-reactive protein: a bidirectional Mendelian randomization study
AbstractBackgroundLow vitamin D status is often associated with systemic low-grade inflammation as reflected by elevated C-reactive protein (CRP) levels. We investigated the causality and direction of the association between vitamin D status and CRP using linear and non-linear Mendelian randomization (MR) analyses.MethodsMR analyses were conducted using data from 294 970 unrelated participants of White-British ancestry from… Continue reading Vitamin D deficiency and C-reactive protein: a bidirectional Mendelian randomization study
Rapidly Increasing Serum 25(OH)D Boosts the Immune System, against Infections—Sepsis and COVID-19
Vitamin D deficiency is a global public health problem, a pandemic that commonly affects the elderly and those with comorbidities such as obesity, diabetes, hypertension, respiratory disorders, recurrent infections, immune deficiency, and malignancies, as well as ethnic minorities living in temperate countries. The same groups were worst affected by COVID-19. Since vitamin D deficiency weakens… Continue reading Rapidly Increasing Serum 25(OH)D Boosts the Immune System, against Infections—Sepsis and COVID-19
Vitamin D and brain health: an observational and Mendelian randomization study
BackgroundHigher vitamin D status has been suggested to have beneficial effects on the brain. ObjectivesTo investigate the association between 25-hydroxyvitamin D [25(OH)D], neuroimaging features, and the risk of dementia and stroke. MethodsWe used prospective data from the UK Biobank (37–73 y at baseline) to examine the association between 25(OH)D concentrations with neuroimaging outcomes (N =… Continue reading Vitamin D and brain health: an observational and Mendelian randomization study
Effect of active vitamin D treatment on development of type 2 diabetes: DPVD randomised controlled trial in Japanese population
To assess whether eldecalcitol, an active vitamin D analogue2, can reduce the development of type 2 diabetes among adults with impaired glucose tolerance. Design Double blinded, multicentre, randomised, placebo controlled trial. Setting Three hospitals in Japan, between June 2013 and August 2019. Participants People aged 30 years and older who had impaired glucose tolerance defined… Continue reading Effect of active vitamin D treatment on development of type 2 diabetes: DPVD randomised controlled trial in Japanese population
