Vitamin D keeps lungs healthy - CHEST study

Vitamin D may play a role in keeping our lungs healthy, with greater concentrations of vitamin D resulting in greater lung health benefits. A study in the December issue of CHEST, the peer-reviewed journal of the American College of Chest Physicians (ACCP), shows that patients with higher concentrations of vitamin D had significantly better lung function, compared with patients with lower concentrations of vitamin D.

Fee-for-service associated with a significantly higher rate of cataract surgery

A system in which physicians are reimbursed for each procedure they perform (fee-for-service) is associated with a significantly higher rate of cataract surgery and related surgical costs, compared to a system in which physicians receive a lump sum for each patient they manage (contact capitation), according to a study in the December issue of Archives of Ophthalmology.
