Study investigates the cost effectiveness of spinal surgery

(Chicago) – Back pain affects more than 80 percent of people and costs more than $100 billion annually in the U.S. But is the surgery cost effective? A study by researchers at Rush University Medical Center suggests that for patients with spinal stenosis, a laminectomy, or surgical removal of some soft bone and tissue, is a reasonable value. However, for patients with spinal stenosis with associated slipped vertebrae, the benefits of spinal fusion surgery may not be enough to offset costs.

Can't chalk it up to 'baby fat'

Despite recent widespread media attention given to studies that have indicated one-third of American children have a weight problem, a new study shows just one-third of children who are overweight or obese actually receive that diagnosis by a pediatrician. The study, led by researchers at The MetroHealth System and Case Western Reserve University School of Medicine in Cleveland, also stresses that this failure to diagnose appears to mostly impact children who may most greatly benefit from early intervention. The study is published in the January issue of the journal Pediatrics.

Nutrigenomics -- developing personalized diets for disease prevention

New Rochelle, NY, December 29, 2008—The emerging field of nutrigenomics, which aims to identify the genetic factors that influence the body's response to diet and studies how the bioactive constituents of food affect gene expression, is explored in a series of provocative, interdisciplinary reports and analyses in the December 2008 Special Issue (Volume 12, number 4) of OMICS: A Journal of Integrative Biology, a peer-reviewed journal published by Mary Ann Liebert, Inc. (www.liebertpub.com).

Third-hand smoke: Another reason to quit smoking

Need another reason to add "Quit Smoking" to your New Year's resolutions list? How about the fact that even if you choose to smoke outside of your home or only smoke in your home when your children are not there – thinking that you're keeping them away from second-hand smoke – you're still exposing them to toxins? In the January issue of Pediatrics, researchers at MassGeneral Hospital for Children (MGHfC) and colleagues across the country describe how tobacco smoke contamination lingers even after a cigarette is extinguished – a phenomenon they define as "third-hand" smoke.

Another reason to avoid high-fat diet -- it can disrupt our biological clock

Jerusalem, December 28, 2008 – Indulgence in a high-fat diet can not only lead to overweight because of excessive calorie intake, but also can affect the balance of circadian rhythms – everyone's 24-hour biological clock, Hebrew University of Jerusalem researchers have shown.

The biological clock regulates the expression and/or activity of enzymes and hormones involved in metabolism, and disturbance of the clock can lead to such phenomena as hormone imbalance, obesity, psychological and sleep disorders and cancer.

Fungal pill could provide asthma relief for 150,000 UK sufferers

Up to 150,000 people suffering from severe asthma in the UK could benefit from taking antifungal medication already available from pharmacists, new research has found.

University of Manchester scientists found that pills used to treat everyday fungal infections greatly improved symptoms of asthma in those patients that had an allergic reaction to one or more fungi.

Flowering plants speed post-surgery recovery

MANHATTAN, KS—Contact with nature has long been suspected to increase positive feelings, reduce stress, and provide distraction from the pain associated with recovery from surgery. Now, research has confirmed the beneficial effects of plants and flowers for patients recovering from abdominal surgery.

Another reason to get your hands dirty

MANHATTAN, KS—The Centers for Disease Control and Prevention and the American College of Sports Medicine recommends at least 30 minutes of moderate-intensity physical activity on most days of the week in order to maintain and improve optimal health. This recommendation is especially important for older Americans, who can be less likely to fulfill this requirement, yet are more at risk for chronic diseases associated with aging.

New use for human hair

VERONA, MS—Agricultural crop production relies on composted waste materials and byproducts, such as animal manure, municipal solid waste composts, and sewage sludge, as a necessary nutrient source. Studies have shown that human hair, a readily available waste generated from barbershops and hair salons, combined with additional compost, is an additional nutrient source for crops. Although human hair has become commercially available to crop producers in the past couple years, it has not been proven to be an exclusive source of nutrients in greenhouse container production.

Minimizing obesity's impact on ovarian cancer survival

BIRMINGHAM, Ala. – Obesity affects health in several ways, but new research shows obesity can have minimal impact on ovarian cancer survival. A study by researchers at the University of Alabama at Birmingham (UAB) Comprehensive Cancer Center found ovarian cancer survival rates are the same for obese and non-obese women if their chemotherapy doses are closely matched to individual weight.

Study examines impact of managed care on stroke prevention surgery

DALLAS – Dec. 29, 2008 – Policymakers and economists often promote managed-care plans based on the assumption that they prevent the overuse of unnecessary surgical procedures or help steer patients to high-quality providers, compared to traditional fee-for-service insurance plans. A recent study by a researcher at UT Southwestern Medical Center, however, found that in the case of one common surgical procedure, the checks and balances assumed with managed care did not improve the quality or outcome of care.

Acute gastric injury due to high-dose analgesics?

Analgesics, NSAIDs and acetaminophen, are commonly used for the relief of fever, headaches, and other minor aches and pains. The gastrointestinal side effects of NSAIDs are well documented and acetaminophen is accepted to be a safe drug for the gastrointestinal system. Acute effects of short-term, especially high-dose NSAID and acetaminophen use have not been studied adequately.

How to enhance non-thermal effects of ultrasound

In recent years HIFU has been widely used for the treatment of solid tumors, such as liver tumor, bone tumor, and breast cancer. The mechanism for therapeutic actions of HIFU includes thermal effects and non-thermal effects with the latter dominated by cavitational effects. Adjusting acoustic parameters of pulsed high intensity focused ultrasound (PHIFU) can control thermal effects and non-thermal effects; short duty cycle and high intensity favors the occurrence of cavitation. Ultrasound contrast agent (UCA) can enhance cavitational effects.

Global structures of the DE3 tide

Researchers from LAGEO , the Institute of Atmospheric Physics, has shown that the DE3 tide can propagate up to above 110 km height and exhibits 2-year cycle oscillation. Among all the diurnal tides in the upper atmosphere, this tide is the most prominent component other than the migrating diurnal tide. Moreover, its importantance has been highlighted in recent years as it is considered as a main mechanism responsible for the generation of a typical ionospheric disturbance, implying its involvement into the ionospheric dynamo.

4 years after tsunami: Corals stage comeback

NEW YORK (DECEMBER 26, 2008) – A team of scientists from the New York-based Wildlife Conservation Society (WCS) has reported a rapid recovery of coral reefs in areas of Indonesia, following the tsunami that devastated coastal regions throughout the Indian Ocean four years ago today.
