Children who use community health centers may be at a particularly high risk of being obese, according to a new study. This association between obesity and the type of health delivery system used was present regardless of race, ethnicity or geographic characteristics.
Researchers studied nearly 2,500 children aged two to 11, in medically underserved areas of the mid-Atlantic states, West Virginia, and Puerto Rico. These medically underserved areas, mainly inner-city and rural
Savings and consumption decisions will be more efficient if households have the opportunity to borrow and save as they wish. This in turn would lead to more consumption, and therefore overall growth. The accuracy of this prediction is clearly borne out by developments in Sweden from 1980 to 2000, which is shown in Mårten Bjellerup’s dissertation Essays on Consumption: Aggregation, Asymmetry, and Asset Distributions. Greater opportunities to borrow money in various ways provided households with
Novel approach may address viral resistance
Researchers have confirmed for the first time the benefit of an innate defense system present in the few patients who remain healthy after years of infection with HIV despite receiving no treatment, according to an article published in the September edition of the Journal of Virology. The study found that the subset of HIV-infected patients referred to as long-term survivors or nonprogressors have higher amounts of a key enzyme in their
World’s largest study on acute coronary syndromes
A Canadian-led study involving researchers from 41 countries has demonstrated in the world’s largest study of acute coronary syndromes (ACS) that a new anti-thrombotic therapy is safer and as effective as the traditional therapy used in preventing heart attacks, death and ischemia in people with serious heart conditions.

In patients with an increased risk of heart rhythm problems, cardiac arrest or arrhythmia, eating fish oil did little to reduce that risk. This is the conclusion of a European multi-centre study reported by Brouwer and colleagues of the Wageningen Centre for Food Sciences (WCFS) at the European Society of Cardiology meeting in Stockholm. The findings of this trial do not support strong anti-arrhythmic effects that have been attributed to fish oil in the past. The Study on Omega-3 Fatty acids and
Assistant lecturer at the Public University of Navarra, José Javier Gil Soto, is the author of the thesis “Preprocesser for dynamic simulation of multibody systems based on symbolic algebra”. The work undertakes the conceptual development and subsequent implementation of a symbolic system that enables the putting forward and resolution, in a simple manner, of the most common problems in classical mechanics.

Low doses of the active form of vitamin D and non-steroidal anti-inflammatory drugs, taken in combination, have been shown to act as a powerful one-two punch that knocks down the growth of prostate cancer cells.
In a study published in the journal “Cancer Research”, scientists from Stanford University discovered that the amount of both — activated vitamin D, or calcitriol, and the NSAIDs — could be reduced by half to one-tenth the dosage to thwart prostate cancer cell growth
According to two studies published today in the American Gastroenterological Association (AGA) journal Gastroenterology, people with inflammatory bowel disease are more prone to developing severe disorders of the respiratory and nervous systems. The studies found an increase in the prevalence of asthma, arthritis, chronic renal disease, multiple sclerosis and psoriasis, among other disorders. “These studies remind us that the effects of inflammatory bowel disorders extend to every corner of the
Study suggests cirrhosis and liver disease nearly inevitable for people with hep C
Nearly 80 percent of chronic hepatitis C sufferers who have the disease for several decades will develop cirrhosis or end-stage liver disease later in life, according to a study published today in the American Gastroenterological Association (AGA) journal Clinical Gastroenterology and Hepatology. Researchers found that it is highly likely that people who are infected with hepatitis C (HCV) for mor
New findings suggest balancing Chk1 activity will produce less toxic cancer drugs
A study published by The Burnham Institute in the September edition of Molecular Cell reports that a cell-cycle checkpoint protein, known to be activated by an important class of anticancer drugs, may play crucial roles in both the hampering of therapeutic actions and aiding cancer cells to “recover” and start dividing again after treatment with these drugs. The study is expected to help academic r
A new study by Yale researchers shows that prior nicotine exposure in mice can increase their motivation to respond work for food, weeks after their last exposure to nicotine, a finding that runs counter to the popular belief that nicotine exposure curbs appetite.
The study, to be published in an upcoming issue of Psychopharmacology, also sheds new light on the role played by certain nicotinic acetylcholine receptors when it comes to the reinforcing aspects of nicotine.
Tranquilizers work better than placebos at treating the symptoms of alcohol withdrawal syndrome but they may not work better than other drugs, according to a new review of recent studies.
The class of depressant drugs known as benzodiazepines are especially effective at treating seizure in withdrawal patients, say Dr. Christos Ntais of the University of Ioannina School of Medicine in Greece and colleagues. People given benzodiazepines were 84 percent less likely to have wi
The effort required to correctly hear and identify words may diminish the resources needed to memorize them
In a new study, Brandeis University researchers conclude that older adults with mild-to-moderate hearing loss may expend so much cognitive energy on hearing accurately that their ability to remember spoken language suffers as a result.
The study, published in Current Directions in Psychological Science, showed that even when older adults could hear words well enoug
A new global study involving long-term data from satellites and ground stations indicates Earth’s ozone layer, while still severely depleted following decades of thinning from industrial chemicals in the atmosphere, is no longer in decline.
Betsy Weatherhead, a researcher with the Cooperative Institute for Research in Environmental Sciences, a joint institute of the University of Colorado at Boulder and the National Oceanic and Atmospheric Administration and corresponding
Do wildfires influence the housing market? Is it a consideration when people buy or build?
Geoffrey Donovan, an economist at the USDA Forest Service’s Pacific Northwest Research Station in Portland, Ore., and his colleagues collaborated with the Colorado Springs Fire Department in Colorado to answer these questions.
The fire department developed a computer model to rate the wildfire risk of 35,000 parcels in the city’s wildland-urban interface. Each parcel
Rats given morphine show bigger biological and behavioral signs of stress-induced anxiety even after going off the drug
A new study has found that opiate drugs such as morphine leave animals more vulnerable to stress. This means that stress and opiates are in a vicious cycle: Not only does stress trigger drug use, but in return the drug leaves animals more vulnerable to stress. The study, conducted at the University of New South Wales, helps to explain why people who use opiates
