Obesity and extreme obesity during early childhood are likely to continue into adulthood. Understanding trends in extreme obesity is important because the prevalence of cardiovascular risk factors increases with severity of childhood obesity," writes Liping Pan, M.D., M.P.H., of the Centers for Disease Control and Prevention, Atlanta, and colleagues. National trends in extreme obesity among young children living in low-income families have not been known. http://medicalxpress.com/news/2012-12-obesity-declining-preschool-aged-children-low-income.html Overweight and Obesity Tue, 25 Dec 2012 16:00:05 EST news275576788 The age-adjusted prevalence of chronic obstructive pulmonary disease (COPD) varies considerably within the United States, from less than 4 percent of the population in Washington and Minnesota to more than 9 percent in Alabama and Kentucky.

the dean of UCLA's School of Nursing has found a direct correlation between pressure ulcers—commonly known as bedsores—and patient mortality and increased hospitalization.   The research is believed to be the first of its kind to use data directly from medical records to assess the impact of hospital-acquired pressure ulcers on Medicare patients at national and state levels.   According to the study, featured as the lead article in the current issue of the Journal of the American Geriatrics Society, seniors who developed pressure ulcers were more likely to die during their hospital stay, to have longer stays in the hospital, and to be readmitted to the hospital within 30 days of their discharge. http://medicalxpress.com/news/2012-10-hospital-bedsores-patient-mortality.html Health Tue, 02
