Philadelphia, PA, 8 December, 2010 - A study of long-term, active duty military personnel who used Department of Veterans Affairs' health services showed that childhood maltreatment and other high magnitude stressors, such as being in a serious accident or a natural disaster, were more strongly associated with participants' current psychiatric symptoms than were their military sexual experiences, such as sexual harassment. The research, described in issue 44 -16 of the Journal of Psychiatric Research, was completed by Dr. Maureen Murdoch and colleagues of the Minneapolis ...

ANN ARBOR, Mich. — Patients who have complications after colorectal cancer surgery are less likely to get chemotherapy, even when it is clearly recommended for their diagnosis, a new study from the University of Michigan Comprehensive Cancer Center finds. In addition, patients with complications were more than twice as likely to have their chemotherapy delayed for more than 120 days after diagnosis or two months after surgery, which is considered the appropriate timeframe for receiving chemotherapy. "Surgical complications are typically thought to be short-term problems, ...

Haifa / Leipzig. The fire disaster in the Carmel Mountains near Haifa is a typical example of climate change effect and a taste of the future, says Dr. Guy Pe'er, one of the authors of Israel's first report to the UN on climate change. Ten years ago, Dr. Pe'er and other Israeli scientists collated knowledge about the effects of climate change for Israel. They warned already in the year 2000 of expected climatic fluctuations, heat events, decreased rainfall and delayed late winter rainfall, all of which would lead to increased risk of intense forest fires. According to ...

BEIJING -- Responding to the challenges posed by a rapidly aging population will be one of the most difficult tasks for Asian governments in the first half of this century, says a report released today by the Chinese Academy of Social Sciences, Indian National Science Academy, Indonesian Academy of Sciences, U.S. National Academy of Sciences, and the Science Council of Japan. The report, which discusses these challenges and identifies needed research to help policymakers better respond to them, was released at the opening of an international conference on aging in ...

Targeting the core social deficits of autism spectrum disorders (ASD) (http://www.nimh.nih.gov/health/topics/autism-spectrum-disorders-pervasive-developmental-disorders/index.shtml) in early intervention programs yielded sustained improvements in social and communication skills even in very young children who have ASD, according to a study funded by the National Institute of Mental Health (NIMH), part of the National Institutes of Health. The study was published online December 8, 2010, in the Journal of Child Psychology and Psychiatry. Although some research suggests ...

If skin is the body's fortress against germ invaders, shouldn't minimally invasive surgeries – operations guided by camera probes, conducted entirely within the abdomen – carry less risk for serious infection than procedures that slice the same cavity wide open? New research published in the December Annals of Surgery is challenging that assumption – at least for a subset of patients. Researchers from theUniversity of Rochester Medical Center (URMC) analyzed thousands of appendectomies (appendix removals) and found that, for a small group, the danger of deep abdominal ...

Researchers from the Max Planck Institute for Marine Microbiology in Bremen, Germany and the Massachusetts Institute of Technology (M.I.T.) in Cambridge, Massachusetts have found a remarkable effect while studying how marine particles sink, which could affect the way scientists assess global carbon fluxes. Their question - How fast does organic material and debris clumped together forming porous particles settle to the sea floor? Microbes colonizing these particles degrade the organic matter and release carbon dioxide back to the water. The downward velocity of the particles ...

COLUMBUS, Ohio – One of the world's foremost experts on climate change is warning that if humans don't moderate their use of fossil fuels, there is a real possibility that we will face the environmental, societal and economic consequences of climate change faster than we can adapt to them. Lonnie Thompson, distinguished university professor in the School of Earth Sciences at Ohio State University, posed that possibility in a just-released special climate-change edition of the journal The Behavior Analyst. He also discussed how the rapid and accelerating retreat of the ...

ROCHESTER, Minn. -- Mayo Clinic (http://www.mayoclinic.org/) researchers found that the part of the brain generating seizures in individuals with epilepsy is functionally isolated from surrounding brain regions. The researchers hope this finding could be a clinical biomarker to help identify individuals with abnormal brain function. This study was presented at the American Epilepsy Society's (http://www.aesnet.org/) annual meeting in San Antonio on Dec. 4. Epilepsy (http://www.mayoclinic.org/epilepsy/) is a disorder characterized by the occurrence of two or more seizures. ...

Milan, Italy, 8 December 2010 – Attention Deficit Hyperactivity Disorder (ADHD) and developmental reading disability (RD) are complex childhood disorders that frequently occur together; if a child is experiencing trouble with reading, symptoms of ADHD are often also present. However, the reason for this correlation remains unknown. A new study reported in the latest special issue of Cortex (http://www.sciencedirect.com/science/journal/00109452), dedicated to "Developmental Dyslexia and Dysgraphia", has suggested that the disorders have common genetic influences, which may ...

A new study by researchers at the Johns Hopkins Center for Injury Research and Policy finds that youth generally perceive community street outreach workers positively, regardless of whether they have personally worked with one. Street outreach workers are typically members of the community who intervene to prevent conflict and retaliation, and in some programs, also connect individuals with needed services, such as housing, health care and job training. While communities across the United States are increasingly using street workers as a strategy to connect at-risk youth ...

Milan, Italy, 8 December 2010 – Learning to read and write are complex processes, which can be disrupted in various ways, leading to disorders known as dyslexia and dysgraphia. Two new studies, published in a recent special issue of Elsevier's Cortex (http://www.sciencedirect.com/science/journal/00109452) provide evidence of this variety, suggesting that effective treatment needs to take it into account. A group of researchers from the Universities of Bari and Rome in Italy studied the reading and writing abilities of 33 Italian dyslexic children, comparing their performance ...

Catnip, the plant that attracts domestic cats like an irresistible force, has proven 99 percent effective in repelling the blood-sucking flies that attack horses and cows, causing $2 billion in annual loses to the cattle industry. That's the word from a report published in ACS' biweekly Journal of Agricultural and Food Chemistry. Junwei Zhu and colleagues note that stable flies not only inflict painful bites, but also transmit multiple diseases. Cattle harried by these bloodsuckers may produce less meat and milk, have trouble reproducing, and develop diseases that can ...

Contrary to popular belief, birth control pills account for less than 1 percent of the estrogens found in the nation's drinking water supplies, scientists have concluded in an analysis of studies published on the topic. Their report suggests that most of the sex hormone — source of concern as an endocrine disruptor with possible adverse effects on people and wildlife — enters drinking water supplies from other sources. The report appears in ACS' biweekly journal Environmental Science & Technology. Amber Wise, Kacie O'Brien and Tracey Woodruff note ongoing concern about ...

ANN ARBOR, Mich.---Under just the right conditions---which involve an ultra-high-intensity laser beam and a two-mile-long particle accelerator---it could be possible to create something out of nothing, according to University of Michigan researchers. The scientists and engineers have developed new equations that show how a high-energy electron beam combined with an intense laser pulse could rip apart a vacuum into its fundamental matter and antimatter components, and set off a cascade of events that generates additional pairs of particles and antiparticles. "We can ...

The enzyme that makes fireflies glow is lighting up the scientific path toward a long-sought new medical imaging agent to better monitor treatment with heparin, the blood thinner that millions of people take to prevent or treat blood clots, scientists are reporting. Their study appears in the ACS' monthly journal Bioconjugate Chemistry. Bruce Branchini and colleagues describe a need for new medical imaging agents that emit near-infrared light — the light rays that "night vision" technology detects, enabling soldiers to see in the dark. Those rays penetrate deeper into ...

High-fiber foods are on the way to becoming tastier and more appealing to consumers thanks to new types of dietary fiber now under development. These consumer friendlier forms of fiber, which could be a boon to health, are the topic of an article in the current issue of Chemical & Engineering News (C&EN), ACS' weekly newsmagazine. C&EN Associate Editor Jyllian Kemsley notes that dietary fiber plays key roles in human health. Fiber creates a feeling of fullness that can reduce calorie intake, and provides an energy source for beneficial bacteria in the digestive tract. ...

The conference was ...

Home health care technology may provide one important solution to global concerns about how to sustain health care systems threatened by rising costs and manpower shortages, but such a change faces multiple obstacles to adoption, according to a new RAND Corporation study. The study finds that a wide array of health care stakeholders agree that expanding home-based health tools could give patients a greater ability to self-manage their conditions in partnership with their medical providers, and help improve their health and overall well-being. However, moving care to ...

Experts at The University of Nottingham have developed a new 'score' to help GPs detect heart disease in younger people - before it damages their health. Using data from the electronic health records of over two and half million people researchers have developed, validated and evaluated the new lifetime 'score' which takes account, among many other factors, social deprivation and ethnicity. The results of their research is published today (9 Dec 2010) in the BMJ. Julia Hippisley-Cox, Professor of Clinical Epidemiology and General Practice in the School of Community ...

The report "Assessment of Arsenic Concentrations in Domestic Well Water, by Town, in Maine, 2005-09" and maps are posted online. Potentially harmful arsenic levels have been found in private water wells in towns across Maine where elevated arsenic risks were not previously suspected. Arsenic levels in some private wells exceeded the federal safety standard for public drinking water by ten to one-hundred times or more, according to findings released today by the U.S. Geological Survey. The study is the largest of its kind in Maine. "We found large differences in concentrations ...

Researchers from Queen Mary, University of London, the University of Fribourg and the Paul Scherrer Institut (Villigen, Switzerland) have shown that a magnetically polarised current can be manipulated by electric fields. Published this week in the journal Nature Materials, this important discovery opens up the prospect of simultaneously processing and storing data on electrons held in the molecular structure of computer chips - combining computer memory and processing power on the same chip. "This is especially exciting, as this discovery has been made with flexible ...

Montreal, December 8, 2010 – Zen meditation has many health benefits, including a reduced sensitivity to pain. According to new research from the Université de Montréal, meditators do feel pain but they simply don't dwell on it as much. These findings, published in the month's issue of Pain, may have implications for chronic pain sufferers, such as those with arthritis, back pain or cancer. "Our previous research found that Zen meditators have lower pain sensitivity. The aim of the current study was to determine how they are achieving this," says senior author Pierre ...

Large birds, such as storks, save energy on the flight to their wintering grounds by soaring through the air on thermal currents. Until now, however, we knew nothing about the flight patterns of small migrating songbirds, such as whether they flap their wings or soar and whether these styles of flight allow them to save energy. Now, a team of scientists at the Max Planck Institute for Ornithology in Radolfzell, Ben-Gurion-University of the Negev, and Hebrew University of Jerusalem have tracked the movement of European bee-eaters (Merops apiaster) along the Africa-Eurasia ...

New Rochelle, NY, December 8, 2010—As the prevalence of childhood obesity approaches epidemic levels, physicians on the "front line" need to become more involved in obesity prevention and weight management to reverse this dangerous trend among their young patients. But several obstacles discourage pediatricians and other primary care physicians from taking a more active role in managing childhood obesity. An expert panel identified these barriers and explored strategies for overcoming them in a Roundtable Discussion on "New Ways to Overcome Old Barriers: Engaging Pediatricians ...
