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.
Body
The amount of intra-abdominal fat appears to be associated with the risk of complications following major liver surgery, according to a report in the November issue of Archives of Surgery, one of the JAMA/Archives journals. However, appearing overweight or having a high body mass index (BMI) were not associated with increased post-surgical risks.
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.
A study involving 30 patients suggests that robotic-assisted surgery involving complex pancreatic procedures can be performed safely in a high-volume facility, 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.
Patients who undergo radiation therapy for head and neck cancer appear more likely to experience hearing loss and to be more disabled by its effects than those who do not receive such treatment, according to a report in the November issue of Archives of Otolaryngology–Head & Neck Surgery, one of the JAMA/Archives journals.
In a small, short-term study, a preservative-free, acidified nasal spray appears safe and well tolerated and maintained its sterility in an applicator used multiple times, according to a report in the November issue of Archives of Otolaryngology–Head & Neck 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.
(Cincinnati, OH) – A groundbreaking study published Friday in the leading scientific journal, Cell, revealed that a team of investigators had successfully generated nerve cells using skin cells from four individuals with Rett syndrome. The study, funded in part by IRSF, was led by Dr. Alysson Muotri at the University of California, San Diego--a leading researcher in the stem cell field.
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.
HOUSTON - Red-blood-cell-boosting drugs used to treat anemia may undermine breast cancer treatment with Herceptin, a targeted therapy that blocks the cancer-promoting HER2 protein, researchers from The University of Texas MD Anderson Cancer Center report in the Nov. 16 edition of Cancer Cell.
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.
CAMBRIDGE, Mass. -- A sophisticated new examination of teeth from 11 Neanderthal and early human fossils shows that modern humans are slower than our ancestors to reach full maturity. The finding suggests that our characteristically slow development and long childhood are recent and unique to our own species, and may have given early humans an evolutionary advantage over Neanderthals.
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. An important part of the evidence that identified him as the source of the women's infection came from experts at Baylor College of Medicine (www.bcm.edu) and The University of Texas at Austin (www.utexas.edu/).
AUSTIN, Texas—The source of HIV infection in two separate criminal cases in which men were convicted of intentionally infecting their female sexual partners was confirmed by scientists from The University of Texas at Austin and Baylor College of Medicine using evolutionary forensics.
The research shows it's possible to identify the source of a cluster of diseases by analyzing the evolution of a virus within its host and between individuals. This type of research is known broadly as phylogenetic analysis.
