The availability of healthy food choices and your quality of diet is associated with where you live, according to two studies conducted by researchers at the Johns Hopkins Bloomberg School of Public Health. Researchers examined healthy food availability and diet quality among Baltimore City and Baltimore County, Md., residents and found that availability of healthy foods was associated with quality of diet and 46 percent of lower-income neighborhoods had a low availability of healthy foods.

Boston, MA—A new statistical model could be used to predict an individual's lifetime risk of stroke, finds a study from the Children's Hospital Informatics Program (CHIP). Using genetic information from 569 hospital patients, the researchers showed that their predictive model could estimate an individual's overall risk of cardioembolic stroke -- the most common form of stroke -- with 86 percent accuracy. The findings are reported in the March issue of Stroke.

As influenza season shifts into high gear, with 24 states now reporting widespread activity, the nation's infectious diseases experts are urging supermarket pharmacies with free-antibiotics promotions to educate their customers on when antibiotics are the right prescription—and when they can do more harm than good.

February 25, 2009-- An extreme heat wave affected much of the state of California during mid- to late July 2006, breaking daily maximum temperature records in many regions of the State. A study conducted by researchers from the Mailman School of Public Health, the Natural Resources Defense Council, and the California Department of Public Health reports that the 2006 California heat wave had a substantial impact on morbidity throughout California, resulting in increased hospitalizations and emergency department (ED) visits.

ALEXANDRIA, VA — A new review article published in the Journal of the American Academy of Orthopaedic Surgeons should help convince many patients with low back pain to consider physical therapy as a first line of treatment for their condition, according to the American Physical Therapy Association (APTA). The review, published in February 2009, recommends that in most cases of symptomatic lumbar degenerative disc disease, a common cause of low back pain (LBP), the most effective treatment is physical therapy combined with anti-inflammatory medications.

The wide-ranging IPY findings result from more than 160 endorsed science projects assembled from researchers in more than 60 countries. Launched in March 2007, the IPY covers a two-year period to March 2009 to allow for observations during the alternate seasons in both polar regions. A joint project of WMO and ICSU, IPY spearheaded efforts to better monitor and understand the Arctic and Antarctic regions, with international funding support of about US$ 1.2 billion over the two-year period.

(PHILADELPHIA) – Two-thirds of patients referred for psychiatric services following an emergency room visit are likely to reach only an answering machine when they call for help, compared to about 20 percent of patients calling medical clinics with physical symptoms. Only 10 percent of all calls to mental health clinics in nine U.S. cities resulted in an appointment scheduled within two weeks, according to a new University of Pennsylvania School of Medicine study published in Annals of Emergency Medicine.

Starting with the tiny fruit fly, and then moving into mouse and human patients, researchers at VIB connected to the Center for Human Genetics (K.U. Leuven) showed that the same gene suppresses cancer in all three. Reciprocally, switching off the gene leads to cancer. The scientists think there is a good chance that the gene can be switched on again with a drug. They report their findings in the reputed scientific journal PLoS Biology.

A team of scientists, led by the University of Exeter, has used game theory to explain the bizarre behaviour of a group of ravens. Juvenile birds from a roost in North Wales have been observed adopting the unusual strategy of foraging for food in 'gangs'. New research, published in the journal PLoS One (on Wednesday 25 February 2009), explains how this curious behaviour can be predicted by adapting models more commonly used by economists to analyse financial trends.

Post-partum haemorrhage (PPH) immediately after giving birth is the largest threat to new mothers in high-income countries. An Australian study, featured in the open access journal BMC Pregnancy and Childbirth, shows that an increasing number of women suffered severe problems arising from blood loss after delivery.

Veterinarians frequently suffer psychosocial stress and demoralization associated with heavy workloads. Research published in BioMed Central's open access Journal of Occupational Medicine and Toxicology analyses the extent of the problem and reveals a complex relationship with binge drinking, tobacco consumption and drug use.

Women undertaking a ten week program of 75 minute Restorative Yoga (RY) classes gained positive differences in aspects of mental health such as depression, positive emotions, and spirituality (feeling calm/peaceful) compared to the control group. The study, published today in a special issue of Psycho-Oncology focusing on physical activity, shows the women had a 50% reduction in depression and a 12% increase in feelings of peace and meaning after the yoga sessions.

Most wild species are expected to colonise northwards as the climate warms, but how are they going to get there when so many landscapes are covered in wheat fields and other crops? A study published today (Wednesday 25 February 2009) shows it is possible to predict how fast a population will spread and reveals the importance of habitat conservation in helping threatened species survive environmental change

Obese adolescents have the same risk of premature death in adulthood as people who smoke more than 10 cigarettes a day, while those who are overweight have the same risk as less heavy smokers, according to research published on bmj.com today.

Smoking and obesity are two of the most important behavioural risk factors for premature death in the western world, but it is not known whether smoking and weight have combined effects on the risk of death.

Before flying off the handle the next time someone cuts you off in traffic, consider the latest research from Yale School of Medicine researchers that links changes brought on by anger or other strong emotions to future arrhythmias and sudden cardiac arrests, which are blamed for 400,000 deaths annually.
