Does Air Pollution Affect Osteoporosis? Science Finds A Connection
Women over 50 are already at a higher risk of osteoporosis, but a new study from Columbia University’s Mailman School of Public Health in New York has determined that elevated levels of air pollutants can contribute to bone damage in postmenopausal women. The study found that the effects of air pollution were most evident in the lumbar spine, “with nitrous oxides twice as damaging to the area than seen with normal aging,” according to a press release about the study.

Hydrochlorothiazide And Prevention Of Kidney-Stone Recurrence
Nephrolithiasis is one of the most common conditions affecting the kidney and is characterized by a high risk of recurrence.

Furthermore, dose–response data are also limited. (Dhayat et al, 3/1)
