Can a ray of sunshine help the critically ill?
Scientists have long believed that vitamin D, which is naturally absorbed from sunlight, has an important role in the functioning of the body's autoimmune system. To measure the impact of vitamin D levels on the survival of critically ill patients, the researchers designed an observational study. Over the course of six months, 130 patients over the age of 18 admitted to an intensive care unit of a TAU–affiliated hospital and requiring mechanical ventilation were admitted to the study. Patients who had taken vitamin D supplements prior to admittance were excluded from the study population.
