Benefits of safe sunlight exposure: vitamin D and beyond.

J Steroid Biochem Mol Biol 2021 Jul 27:105957. Epub 2021 Jul 27.

Department of Pathology, Lake Erie College of Osteopathic Medicine, Erie, Pennsylvania, USA. Electronic address:

This review examines the beneficial effects of ultraviolet radiation on systemic autoimmune diseases, including multiple sclerosis and type I diabetes, where the epidemiological evidence for the vitamin D-independent effects of sunlight is most apparent. Ultraviolet radiation, in addition to its role in the synthesis of vitamin D, stimulates anti-inflammatory pathways, alters the composition of dendritic cells, T cells, and T regulatory cells, and induces nitric oxide synthase and heme oxygenase metabolic pathways, which may directly or indirectly mitigate disease progression and susceptibility. Recent work has also explored how the immune-modulating functions of ultraviolet radiation affect type II diabetes, cancer, and the current global pandemic caused by SARS-CoV-2. Read More

Parental resistance to oral vitamin K prophylaxis was much more common in Swiss birthing centres than private or public hospitals.

Acta Paediatr 2021 Jul 30. Epub 2021 Jul 30.

Faculty of Biology and Medicine, University of Lausanne, Lausanne, Switzerland.

Vitamin K deficiency bleeding is a haemorrhagic condition that puts newborn infants at increased risk of bleeding during the first six months of life. The consequences can be disastrous, including lifelong disabling neurological sequelae or death, and can be prevented by a single intramuscular injection of vitamin K at birth. This is regularly cited as the prophylaxis gold standard for its simplicity of administration and efficacy when patients have cholestasis, although repeated oral vitamin K doses have comparable efficacy.

[Deficient micronutrient status of the population of various countries as a risk factor in COVID-19].

Probl Sotsialnoi Gig Zdravookhranenniiai Istor Med 2021 Jun;29(Special Issue):593-597

N. A. Semashko National Research Institute of Public Health, 105064, Moscow, Russia.

The article provides an overview of scientific information on the modern features of the micronutrient status of the population of different countries of the world. It is emphasized that in conditions of epidemiological risk, it is necessary to take into account the provision of micronutrients for various social groups of the population: children, elderly people with a low socio-economic status, as well as those with chronic diseases. As a result of the analysis, it is determined that the deficient micronutrient status contributes not only to a high risk of the body's susceptibility to infectious agents, but also negatively affects the course and outcome of an infectious disease.
