Studies show how critical sleep is to maintaining a healthy lifestyle

DARIEN, IL – Three new studies show just how critical it is for adults to seek treatment for a sleep illness and aim for seven to nine hours of sleep each night in order to maintain a healthy lifestyle.

One study of 2,240 adults is the first to examine the link between obstructive sleep apnea (OSA) and mortality in Asians. Results show that all-cause mortality risk was 2.5 times higher and cardiovascular mortality risk was more than 4 times higher among people with severe OSA. The results are consistent with previous studies in the U.S. and other countries.

Impact of bariatric surgery on health depends on type of surgery, patient characteristics

PASADENA, Calif. – Oct. 14, 2013 – The impact of bariatric surgery on risk factors for cardiovascular disease depends on a variety of factors, including the type of surgery, sex of the patient, ethnic background, and pre-surgery body mass index, according to a Kaiser Permanente study published today in Annals of Surgery.

Rapid reversal of diabetes after gastric banding surgery

Clinical researchers from Sydney's Garvan Institute of Medical Research and St. Vincent's Hospital have shown that a form of weight loss surgery, known as 'gastric banding', brings about reversal of diabetes in some patients, and dramatic improvement of glucose tolerance in others, within 12 weeks.

Type 2 diabetes is a complex metabolic disorder that develops over time, with the body becoming progressively less able to control blood sugar levels. High blood sugars cause damage to tissues and organs, and can lead to very serious complications such as kidney failure and blindness.

New imaging technique can identify breast cancer subtypes and early treatment response

PHILADELPHIA — An optical imaging technique that measures metabolic activity in cancer cells can accurately differentiate breast cancer subtypes, and it can detect responses to treatment as early as two days after therapy administration, according to a study published in Cancer Research, a journal of the American Association for Cancer Research.

1 in 10 women drink a little alcohol while pregnant

Researchers in Norway found that negative affectivity is linked to light alcohol use and binge drinking during pregnancy. Results published in Acta Obstetricia et Gynecologica Scandinavica, a journal of the Nordic Federation of Societies of Obstetrics and Gynecology, show 16% of women had light alcohol use in the first trimester and 10% in the second trimester. Binge drinking occurred in 12% of women during their first trimester and 0.5% in the second trimester.

Baylor College of Medicine researchers find community-based weight loss intervention yields greater weight loss than self-help a

NEW YORK – OCTOBER 15, 2013 – A new randomized controlled trial conducted by Baylor College of Medicine researchers and published today as an Article in Press in The American Journal of Medicine finds that overweight and obese adults following a community-based weight loss intervention, namely Weight Watchers, lost significantly more weight than those who tried to lose weight on their own (10.1 lbs. vs. 1.3 lbs. at six months).

Mindfulness-based stress reduction helps lower blood pressure, reports study in Psychosomatic Medicine

Philadelphia, Pa. (October 15, 2013) -- Blood pressure is effectively lowered by mindfulness-based stress reduction (MBSR) for patients with borderline high blood pressure or "prehypertension." This finding is reported in the October issue of Psychosomatic Medicine: Journal of Biobehavioral Medicine, the official journal of the American Psychosomatic Society.

Hospital report cards for hospital-acquired bedsores: How good are the grades?

ANN ARBOR, Mich. — The data Medicare uses to publicly report hospital rates of patients developing pressure ulcers (or bedsores) is not an accurate source for comparing hospitals on how well they prevent the condition, says a new University of Michigan study.

Bedsores are skin wounds often caused by pressure against the skin when staying in one position for too long. They are among many common hospital-acquired conditions Medicare's Hospital Compare website reports in an effort to help consumers compare the quality of their care at different hospitals.

Courses of prenatal corticosteroids not associated with increased death of children

Multiple courses of prenatal corticosteroids, compared with a single course, taken by pregnant women to help prevent preterm birth was associated with no increase or decrease in the risk of death or disability for their children at age 5, according to a study published by JAMA Pediatrics, a JAMA Network publication.

Study finds earlier is better for measles immunization first dose

OAKLAND, Calif., October 14, 2013 — Children receiving measles-containing vaccines at 12-15 months of age have a lower increased risk of fever and seizures than those who receive them at 16-23 months of age, according to a new Kaiser Permanente study published in JAMA Pediatrics.

Compound derived from vegetables shields rodents from lethal radiation doses

WASHINGTON — Georgetown University Medical Center researchers say a compound derived from cruciferous vegetable such as cabbage, cauliflower and broccoli protected rats and mice from lethal doses of radiation.

Their study, published today in the Proceedings of the National Academy of Sciences (PNAS) suggests the compound, already shown to be safe for humans, may protect normal tissues during radiation therapy for cancer treatment and prevent or mitigate sickness caused by radiation exposure.

Why does maximum heart rate drop with age?

AURORA, Colo. (Oct. 11, 2013) Researchers at the University of Colorado have new insight into the age-old question of why maximum heart rate (maxHR) decreases with age. This decrease in maxHR not only limits the performance of aging athletes but it is also a leading cause for nursing home admittance for otherwise-healthy elderly individuals who no longer have the physical capacity required for independent living. We say we're just getting old and slowing down, but exactly what is it that is slowing down?

Sex over survival: Reproductive trait in fish impedes tissue regeneration

New research on the reproductive habits of zebrafish offers an explanation as to why some animals' bodies repair tissues. The research team previously noticed that male zebrafish regenerate their pectoral fins poorly, as compared to females. Their latest findings, publishing in the October 14 issue of the Cell Press journal Developmental Cell, reveal the basis for this sex-specific regenerative deficiency: structures that are used to improve reproductive success. The scenario represents an example of the tradeoffs between reproduction and survival.

Cultural differences may explain why some don't get HPV vaccines

AURORA, Colo. (Oct. 14, 2013) -- A new study explores why girls in minority groups and low-income families, who are most at risk for cervical cancer, may not be getting the human papillomavirus or HPV vaccine.

Researchers from the University of Colorado School of Medicine and Children's Hospital Colorado interviewed 41 low-income parents of girls ages 12-15 to determine why they didn't get the vaccine or finish the course, and included both English speakers and Spanish speakers in the study.

UMMS faculty provide new evidence that aging tumor cells may be an effective cancer treatment

WORCESTER, MA – Scientists at the University of Massachusetts Medical School have shown that diffuse large B-cell lymphoma (DLBCL) may be susceptible to treatment by re-activating the normal aging program in tumor cells so they can no longer divide. The study, published in Nature Communications, details a novel, tumor-suppressive role for the Smurf2 protein—which typically plays an "enforcer" role in cellular aging, also called senescence —in a subset of DLBCL. Identification of this novel function for Smurf2 provides a new therapeutic target for treating this cancer.
