There are a few well-established side effects of bisphosphonates including rare osteonecrosis of the jaw and more common esophageal irritation. However, several more recent case reports suggest a correlation between prolonged bisphosphonate use and…

The Effect of Bariatric Surgery on Incretin Hormones and Glucose Homeostasis

By Michael Crist

Faculty Peer Reviewed

Until recently, little thought was given to the important role played by the duodenum, jejunum, and ileum in glucose homeostasis. The involvement of the gut in glucose regulation is mediated by the enteroinsular axis, which refers to the neural and hormonal signaling pathways that connect the gastrointestinal (GI) tract with pancreatic beta cells. These pathways are largely responsible for the increase in insulin that occurs during the postprandial period. In 1964 McIntyre and colleagues first reported the phenomenon…

By Jeffrey Shyu, MD

Climate change has been linked to a variety of adverse effects on human health, effects that are expected to worsen in the coming decades . For example, a heat wave in August 2003 resulted in nearly 15000 deaths in France, and the anticipated increase in average world temperatures is expected to lead to longer and more frequent heat waves that will disproportionately affect our more vulnerable populations. Infectious disease outbreaks, particularly vector-borne ones such as malaria, are expected…
