For years, pear-shaped people who carry weight in the thighs and backside have been told they are at lower risk for high blood pressure and heart disease than apple-shaped people who carry fat in the abdomen. But new findings from nutrition researchers at Washington University School of Medicine in St. Louis suggest body-shape comparisons don't completely explain risk.

WINSTON-SALEM, N.C. – A medication used for high blood pressure does not improve a common form of heart failure, according to new results from a large, international study.

The study, which included researchers at Wake Forest University Baptist Medical Center in key leadership positions, appears in this week's issue of the New England Journal of Medicine, published today.

Scientists have successfully created the first induced pluripotent stem (iPS) cell lines from adult monkey skin cells. The research, published by Cell Press in the December issue of the journal Cell Stem Cell, demonstrates that the method of direct reprogramming is conserved among species and may be useful for creation of clinically valuable primate models for human diseases.

CINCINNATI – Boys with asthma who are exposed to environmental tobacco smoke have higher degrees of hyperactivity, aggression, depression and other behavioral problems, according to researchers at Cincinnati Children's Hospital Medical Center.

In a study posted online ahead of print by the Journal of Developmental and Behavioral Pediatrics, the researchers said behavioral problems increase along with higher exposure levels, but they added even low levels of tobacco smoke may be detrimental to behavior.

(WASHINGTON, December 3, 2008) – Stem cells derived from bone marrow may serve as a novel therapeutic option to treat a disease called epidermolysis bullosa (EB), a disorder characterized by extraordinarily fragile skin, according to a study prepublished online in Blood, the official journal of the American Society of Hematology.

Many specialized cells, such as in the skin, intestinal mucosa or blood, have a lifespan of only a few days. For these tissues to function, a steady replenishment of specialized cells is indispensable. This is the task of so-called "adult" stem cells also known as tissue stem cells.

Arnhem, 04 December 2008 — The January issue of European Urology, the official journal of the European Association of Urology published by Elsevier, will feature new recommendations on late-onset hypogonadism (LOH), recently formulated by major scientific organizations. LOH is a clinical and biochemical syndrome associated with advancing age and characterized by typical symptoms and a deficiency in serum testosterone levels.

CHICAGO – A new study finds the use of light exposure therapy, dark sunglasses and a strict sleep schedule can help night-shift workers create a "compromise circadian phase position," which may result in increased performance and alertness during night shifts while still allowing adequate nighttime sleep on days off. The study by researchers at Rush University Medical Center is the first to attempt to balance phase delaying and phase advancing light and dark exposure to achieve a specific circadian phase position that improves alertness and performance for night shift workers.

TORRANCE (Dec. 4, 2008) – With less than half of patients with necrotizing soft tissue infections displaying the physical signs of these very serious infections, researchers have found two simple blood tests can help physicians diagnose what is commonly known as "flesh-eating bacteria," according to a study in the December issue of The American Journal of Surgery.

DURHAM, NC -- Fertility patients who are done having children feel responsible for the stored, frozen embryos left over from their treatment, yet more than half are against implanting the embryos in anyone else, according to a new study by researchers at Duke University Medical Center.

"This really turns our moral presumptions on their heads," says Anne Drapkin Lyerly, MD, an obstetrician/gynecologist and bioethicist at Duke, and lead investigator of the findings that appear online in Fertility & Sterility.

Tamoxifen may worsen breast cancer in a small subset of patients. Research published in BioMed Central's open access journal Breast Cancer Research suggests that in patients who show reduced or absent expression of the protein E-cadherin, commonly used anti-oestrogen drugs such as tamoxifen may promote more harmful cancer cell behaviour.

ST. LOUIS –An NIH funded multi-center clinical trial found no benefit from "maintenance therapy," low-dose peginterferon used for hepatitis C patients who have not responded to an initial round of treatment. In addition, the study showed a surprising health decline in patients with liver disease over the course of four years.

Kidney disease patients' ability to understand basic health information may have a significant impact on whether or not they will receive an organ transplant, according to a study appearing in the January 2009 issue of the Clinical Journal of the American Society Nephrology (CJASN). The findings reveal an important disparity in access to care and point to the need for more standardized procedures for referring patients for transplantation.

Despite the well-known dangers of first- and secondhand smoke, an estimated ten percent of pregnant women in the U.S. are smokers. Exposure of a developing baby to harmful cigarette byproducts from mothers who smoke affects an estimated 420,000 newborns each year and poses a significant health care burden.

ST. PAUL, Minn. – New guidelines developed by the American Academy of Neurology find a combination of blood tests and other specialized assessments appear to be the most helpful tests for finding the cause of neuropathy. Also known as neuritis or distal symmetric polyneuropathy, this common nerve problem affects people of all ages. The guidelines are published in the December 3, 2008, online issue of Neurology®, the medical journal of the American Academy of Neurology.
