CHICAGO – Few children leave surgery with a foreign body left inside them, but such events appear most likely to occur during gynecologic operations, according to a report in the November issue of Archives of Surgery, one of the JAMA/Archives journals. This surgical error was associated with longer hospital stays and increased costs, but not with an increased risk of death.

A small study of Japanese surgeons suggests that duration of surgery and the amount of blood loss are associated with increased stress scores, and that night duty is associated with reduced stress arousal scores, according to a report posted online today that will be published in the March print issue of Archives of Surgery, one of the JAMA/Archives journals.

CINCINNATI—University of Cincinnati (UC) researchers have found that applying a stem cell-infused patch together with overexpression of a specific cell instruction molecule promoted cell migration to damaged cardiac tissue following heart attack and resulted in improved function in animal models.

The researchers also found that function improved more so than when stem cells were directly injected in heart tissue—a therapy that is being studied elsewhere.

Irvine, Calif., Nov. 15, 2010 — UC Irvine researchers have discovered that circadian rhythms – the internal body clock – regulate fat metabolism. This helps explain why people burn fat more efficiently at certain times of day and could lead to new pharmaceuticals for obesity, diabetes and energy-related illnesses.

Cambridge, MA, November 15, 2010 - Epizyme, Inc., a company leading the discovery and development of first-in-class, targeted cancer therapeutics against epigenetic targets, today announced the publication of breakthrough new research in the Proceedings of the National Academy of Sciences (USA). The discovery, centered on the epigenetic enzyme EZH2, illuminates a clear path for the translation of basic science into targeted therapies for the safe and effective treatment of specific forms of human lymphomas.

HOUSTON -- (Nov.15, 2010) – In 2009, a Collins County, Texas, jury sentenced Philippe Padieu to 45 years in prison for aggravated assault with a deadly weapon – having sex with a series of women and not telling them he had HIV.
