New study questions role of breast milk in obesity prevention
2015-04-07
(Press-News.org) A new study supports human milk as the optimal first food for babies, but the study raises questions about whether breast milk protects children from becoming obese.
The Cincinnati Children's Medical Center review of more than 80 relevant breastfeeding studies that were conducted over a period of at least 20 years is published in Current Obesity Reports.
"The best observational evidence up to now suggests that exclusively breastfeeding, or at least breastfeeding for a longer time, is associated with a 10 to 20 percent reduction in obesity prevalence in childhood," says Jessica Woo, PhD, a researcher at Cincinnati Children's and a co-author of the study. "Research conducted recently, however, suggests that by understanding the mechanisms of how breastfeeding and the composition of human milk affect infant development, we may be able to generate a more nuanced view of the connection between breastfeeding and obesity risk."
Dr. Woo and her colleague at Cincinnati Children's, Lisa Martin, PhD, suggest three potential biological factors related to breastfeeding that may influence obesity later in life: the role of maternal obesity, the effect of breastfeeding on how the digestive system processes food, and how breastfeeding may influence the risk of childhood obesity through alterations in taste preferences and diet.
"The complex nature of the relationship between breastfeeding and obesity, including the fact that human milk and milk production vary among women, suggests that the medical literature does not promote breastfeeding as a frontline strategy to prevent obesity," says Dr. Martin.

1. Weight Watchers and Jenny Craig come out on top among commercial weight loss programs
Note: Sound bites, b-roll footage, and image available. Satellite coordinates and feed times are below.
Physicians looking for an effective commercial weight-loss program for their overweight and obese patients may want to recommend Weight Watchers or Jenny Craig. According to an updated evidence review of 11 commercial weight-loss programs, only Weight Watchers and Jenny Craig showed evidence for effective long-term weight loss. The review is published in Annals of Internal Medicine. ...

In a bid to help physicians guide obese and overweight patients who want to try a commercial weight-loss program, a team of Johns Hopkins researchers reviewed 4,200 studies for solid evidence of their effectiveness but concluded only a few dozen of the studies met the scientific gold standard of reliability.
In a review of the best research available through late 2014, the results suggest that only a few programs have shown that their users lose more weight than those not using them. The findings are published in the April 6 Annals of Internal Medicine, along with a ...

LOS ANGELES Middle-aged athletes are at low risk for having a sudden cardiac arrest while playing sports, and those who do have a greater chance of surviving the usually-fatal condition, shows a new Cedars-Sinai Heart Institute study.
"Because there is so much media attention when someone has a sudden cardiac arrest while playing sports, we want to make sure people know that the benefits of exercise far outweigh the risk of having a cardiac arrest," said Sumeet S. Chugh, M.D., associate director of the Cedars-Sinai Heart Institute and a prominent expert in the diagnosis, ...

PITTSBURGH, April 6, 2015 - Symptoms from lumbar spinal stenosis, an anatomical impairment common with aging, were relieved and function improved in as many patients utilizing physical therapy as those taking the surgical route, University of Pittsburgh researchers discovered in a two-year study published today in Annals of Internal Medicine.
It is the first study that clearly compared outcomes between surgery and an evidence-based, standardized physical therapy approach for lumbar spinal stenosis. The condition, created by a narrowing of the spinal canal that puts ...

DALLAS, April 6, 2015 --Sudden cardiac arrest during sports activities is relatively low among physically active middle-aged adults, according to research in the American Heart Association journal Circulation.
Sudden cardiac arrest is the abrupt loss of heart function and usually results from an electrical disturbance in the heart that stops blood flow to other vital organs. Administering CPR immediately after the event, before emergency services arrives, can increase the chance of survival.
A review of 1,247 sudden cardiac arrest cases involving men and women ages ...

A new test has been able to measure for the first time the build-up of a harmful mutant protein in the nervous system of patients during the progression of Huntington's disease (HD). Published today in the Journal of Clinical Investigation, the research team behind the findings hope that the new assay will enable the testing of drugs that aim to lower the production of the pathogenic mutant huntingtin protein that causes the disease, and could be useful in predicting or monitoring the progression of HD.
HD is a genetic neurodegenerative disease that usually develops in ...

The rate of emergency department visits in California for non-injuries has risen while the rate of visits for injuries has dropped, according to a new study led by UC San Francisco that documents the increasing amount of care provided in emergency departments for complex, chronic conditions.
The research shows the growing importance of non-trauma cases in the emergency department (ED), the authors said, and it provides an opportunity to better understand the health of people as well as shifting patterns of care, especially among vulnerable populations.
The findings ...

Despite concerns about the increasing costs of treating illnesses like breast cancer, higher treatment costs are linked to better survival rates, according to a study by Yale School of Medicine researchers in the Cancer Outcomes Public Policy and Effectiveness Research (COPPER) Center at Yale School of Medicine and Yale Cancer Center.
The study appears in the April issue of Health Affairs.
"Our findings indicate that in some instances, newer and costlier approaches may be leading to improved outcomes in breast cancer patients," said senior author Cary P. Gross, M.D., ...

Separating circulating cancer cells from blood cells for diagnostic, prognostic and treatment purposes may become much easier using an acoustic separation method and an inexpensive, disposable chip, according to a team of engineers.
"Looking for circulating tumor cells in a blood sample is like looking for a needle in a haystack," said Tony Jun Huang, professor of engineering science and mechanics. "Typically, the CTCs are about one in every one billion blood cells in the sample."
Existing methods of separation use tumor-specific antibodies to bind with the cancer ...

06.04.2015: Rocks do not loose their memory during Earth history but their true ages might be distorted: even under ultra high-temperature metamorphic conditions exceeding 1200°C zircon maintains its lead content accumulated during radioactive decay of uranium and thorium.
Giga year old zircon crystals still contain lead in form of nanometre size spheres of pure lead. However, the inhomogeneous spatial distribution of the lead spheres might falsify ages determined from high-resolution Pb isotope measurement with ion probe.
Zircon is an ideal mineral for age determination ...
