A survey of primary care physician referral to bariatric surgery in Manitoba: access, perceptions and barriers.

Background: There is an important disconnect between surgical programs and primary care physicians (PCP) in the delivery of bariatric care. The objective of this study is to assess PCP knowledge and perception of a provincial bariatric surgery program.

Methods: A 32-question, IRB approved, survey was developed by bariatric surgery experts and vetted by local PCPs.

Modeling the Impact of Microgravity at the Cellular Level: Implications for Human Disease.

A lack of gravity experienced during space flight has been shown to have profound effects on human physiology including muscle atrophy, reductions in bone density and immune function, and endocrine disorders. At present, these physiological changes present major obstacles to long-term space missions. What is not clear is which pathophysiological disruptions reflect changes at the cellular level versus changes that occur due to the impact of weightlessness on the entire body.
