Vitamin D, immune function, and atherosclerosis. Where are we now?

The role of vitamin D in regulating calcium metabolism and skeletal growth and disease is widely recognized. Indeed, current recommendations for serum vitamin D concentrations are based on these parameters. A serum vitamin D <20 ng/mL is considered deficient, concentrations between 20 and 30 ng/mL are insufficient, and >30 ng/mL is adequate.

Cardiomodulatory Effects of Cardiometabolic and Antihyperglycemic Medications: The Roles of Oxidative and Endoplasmic Reticulum Stress.

Uncontrolled hyperglycemia in people with diabetes is an established risk of premature cardiovascular disease. Repeated hypoglycemic events are also associated with increased cardiovascular mortality. Both hyperglycemia and hypoglycemia induce cellular stress, notably endoplasmic reticulum (ER) stress, a known promoter of cardiovascular disease.

Sugar or Sweetener?

Human beings have a natural craving for sweets. The intensity of this craving varies with genetic and environmental factors; however, excessive use of table sugar has been associated with adverse health outcomes, including increased risk of obesity, diabetes mellitus, and cardiovascular disease. As such, the World Health Organization has called for restricting sugar consumption to less than 5% of total energy intake.

Sex- and Age-Associated Differences in Genomic Alterations among Patients with Advanced Non-Small Cell Lung Cancer (NSCLC).

Genomic mutations impact non-small cell lung cancer (NSCLC) biology. The influence of sex and age on the distribution of these alterations is unclear. We analyzed circulating-tumor DNA from individuals with advanced NSCLC from March 2018 to October 2020.
