Body mass index and 25 hydroxyvitamin D status in patients with and without heart failure.

Congestive Heart Failure

Abstract

The purpose of this pilot study was to assess the association between 25-hydroxyvitamin D (25[OH]D) concentrations, vitamin D intake, and sunlight exposure in patients with heart failure (HF) compared with healthy volunteers. Fourteen healthy volunteers 50 and older were recruited to compare with 14 patients with HF. Healthy volunteers were compared with HF patients by serum 25(OH)D concentrations, dietary vitamin D intake, weekly sunlight exposure, and other covariates. Independent sample t tests and linear regression models were used to compare differences between healthy volunteers and patients with HF. The mean serum 25(OH)D concentration was not significantly different between groups (healthy volunteers 25.7 ± 11.1 ng/mL, patients with HF 20.4 ± 10.2 ng/mL; P=.2) and no group effect was found in any multivariable models. Body mass index regardless of group was found to be inversely associated with serum 25(OH)D concentrations (P=.025). There was no difference in the dietary intake of vitamin D or calcium between groups. The healthy volunteers had a significantly greater amount of sunlight exposure but this did not result in higher 25(OH)D when compared with those with HF. Our findings suggest that body mass index has an im...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
