Evidence That Increasing Serum 25(OH)D Concentrations to 30 ng/mL in the Kingdom of Saudi Arabia and the United Arab Emirates Could Greatly Improve Health Outcomes
Biomedicines. 2023 Mar 23;11(4):994. doi: 10.3390/biomedicines11040994.ABSTRACTAccumulating evidence supports the potential protective effects of vitamin D against chronic diseases such as Alzheimer's disease, autoimmune diseases, cancers, cardiovascular disease (ischaemic heart disease and stroke), type 2 diabetes, hypertension, chronic kidney disease, stroke, and infectious diseases such as acute respiratory tract diseases, COVID-19, influenza, and pneumonia, as well as adverse pregnancy outcomes. The respective evidence is based on ecological and observational studies, randomized controlled trials, mechanistic studies, ...

Vitamin D intake and all-cause and cause-specific mortality in Japanese men and women: the Japan Public Health Center-based prospective study
Eur J Epidemiol. 2023 Jan 31. doi: 10.1007/s10654-023-00968-8. Online ahead of print.ABSTRACTWhile higher circulating 25-hydroxyvitamin D concentrations have been reported to be associated with decreased risk of all-cause mortality, evidence on dietary vitamin D intake is limited and inconsistent. We investigated whether vitamin D intake is associated with all-cause and cause-specific mortality among Japanese adults. Participants were 42,992 men and 50,693 women who responded to the second survey of the Japan Public Health Center-based Prospective Study (1995-1998) and who were followed up for mortality through 2018. Dieta...

A repeated measures approach to pooled and calibrated biomarker data
Biometrics. 2021 Dec 30. doi: 10.1111/biom.13618. Online ahead of print.ABSTRACTParticipant level meta-analysis across multiple studies increases the sample size for pooled analyses, thereby improving precision in effect estimates and enabling subgroup analyses. For analyses involving biomarker measurements as an exposure of interest, investigators must first calibrate the data to address measurement variability arising from usage of different laboratories and/or assays. In practice, the calibration process involves reassaying a random subset of biospecimens from each study at a central laboratory and fitting models that r...

VITAL study: How vitamin D and fish oil affect risk of heart attack, stroke and cancer
(Brigham and Women's Hospital) Brigham and Women's Hospital investigators leading the VITamin D and OmegA-3 TriaL (VITAL) conducted a rigorous placebo-controlled trial over the course of 5.3 years, gleaning a treasure trove of information on the effects of both supplements.
