New research led by Kimberly A. Gudzune, MD, MPH, and published in the Annals of Internal Medicine finds that commercial weight-loss programs can offer significant weight loss after one year of participation when compared to a control group, which could be medically significant for many people with obesity or excess weight. According to the authors, many commercial programs show promising weight-loss results, but additional research is needed to better understand the long-term outcomes. Further, given that the programs were not compared directly against one another using the same study and evaluation methods, this research should not be used to rank one program over another.

In the genetic disorder cystic fibrosis (CF), the most severe symptoms are recurring episodes of lung inflammation and bacterial infection (known as “exacerbations”) that happen from one to three times a year and cause ever-increasing amounts of lung damage through the course of a CF patient’s life. While it is well understood that CF lung problems are ultimately due to bacterial infections encouraged by a CF patient’s abnormally thick mucus, medical science has been unable to define specific causes that trigger the periodic flare-ups.

Nearly 40 percent of Americans 60 and older are living with a swallowing disorder known as dysphagia. Although it is a major health problem associated with aging, it is unknown whether the condition is a natural part of healthy aging or if it is caused by an age-related disease that has yet to be diagnosed, such as Parkinson’s disease or amyotrophic lateral sclerosis (ALS). Following a recent study, researchers at the University of Missouri have established a model that identifies aging as a key factor in the development of dysphagia, which may lead to new therapeutic treatments.
