One-to-one telephone health coaching did not seem to reduce hospital use and related costs for patients with long term conditions – and may even lead to increased use, finds a study published on bmj.com today. The study adds weight to the view that health coaching by itself does not appear to reduce hospital activity. The authors suggest that it may be more effective if it were better integrated into the respective care pathways for these groups of patients or were coupled with other interventions. Telephone health coaching is used to provide guidance and support to ...

The length of a human pregnancy can vary naturally by as much as five weeks, according to research published online today (Wednesday) in Europe's leading reproductive medicine journal Human Reproduction [1]. Normally, women are given a date for the likely delivery of their baby that is calculated as 280 days after the onset of their last menstrual period. Yet only four percent of women deliver at 280 days and only 70% deliver within 10 days of their estimated due date, even when the date is calculated with the help of ultrasound. Now, for the first time, researchers ...

COLUMBUS, Ohio -- When it comes to some of the health hazards of light at night, a new study suggests that the color of the light can make a big difference. In a study involving hamsters, researchers found that blue light had the worst effects on mood-related measures, followed closely by white light. But hamsters exposed to red light at night had significantly less evidence of depressive-like symptoms and changes in the brain linked to depression, compared to those that experienced blue or white light. The only hamsters that fared better than those exposed to red ...

A new study of cancer patients indicates that certain patient groups have unmet needs for greater involvement in decisions about their treatment. Cancer patients under 55 and those with some rarer types of cancer want more of a say in the decisions made about their treatment, according to new research being published in the British Journal of Cancer today (Wednesday). Recently, several US states have introduced legislation or other policies supporting share-decision making. The research also shows that ethnic minorities and patients with rectal, ovarian, multiple myeloma ...

DALLAS – Aug. 6, 2013 – Mental health services should be integrated into disaster response as part of emergency services planning, according to a new study by UT Southwestern Medical Center psychiatrists who completed an exhaustive review of articles on the aftereffects of disasters on mental health. The researchers sifted through more than 1,000 articles, reviewing more than 200 that showed disasters can exacerbate existing problems and generate new disorders. Many in the population will experience a natural disaster during their lifetime, while man-made disasters – ...

A Dartmouth-led team has discovered a group of stress-related proteins that explains how plants avoid sunburn in intense light, a finding that one day could help biotechnologists to develop crops that can better cope with hotter, drier conditions occurring in climate change. Their findings appear this week in the journal PNAS. The study, titled "Subset of heat-shock transcription factors required for the early response of Arabidopsis to excess light," was led by researchers from Dartmouth, the Salk Institute for Biological Studies and Australian National University. Too ...

WASHINGTON — The longer a child with minor blunt head trauma is observed in the emergency department, the less likely the child is to require computed tomography (CT) scan, according to the results of a study published online Friday in Annals of Emergency Medicine ("Impact of the Duration of Emergency Department Observation on Computed Tomography Use in Children with Minor Blunt Head Trauma"). "Every hour of observation time in the emergency department was associated with a decrease in CT rates for children whether at low, intermediate or high risk of traumatic brain ...

Feelings of entitlement and superiority that go beyond patriotism and love of country may be a key predictor for Americans who will feel or behave negatively toward undocumented Latino immigrants, according to a study from The University of Texas at Arlington. Researchers looked at those enhanced feelings of superiority - referred to as group-level narcissism – along with a factor called national in-group identification in a new work to be published in the August issue of the Hispanic Journal of Behavioral Science. National in-group identification happens when a person's ...

COLUMBIA, Mo. — According to a recent study, the Summer Community Program offered by the University of Missouri School of Medicine has made a significant impact on physician access in rural communities. The 15-year study showed medical school graduates involved in the program not only entered family practice residency training at higher rates than nonparticipants, but nearly half began their medical careers in rural locations. "In the United States, only about 10 percent of physicians practice in rural areas, and less than 3 percent of entering medical students nationally ...

LONDON, ON – Statins, a class of drugs used to lower cholesterol, are among the best selling drugs in North America and around the world. However, statin myopathy, which results in muscle pain and weakness, is a common side effect affecting up to 10 percent of statin users. A recent study led by Dr. Richard Kim of the Lawson Health Research Institute, in collaboration with Dr. Robert Hegele of Robarts Research Institute, and researchers from Vanderbilt University, found that commonly occurring genetic variations in a person's genes could put them at risk for statin-associated ...

Scientists at the National Physical Laboratory are helping to create electronics capabilities for electric vehicles, with the development of a high temperature capacitor. Electric Vehicles (EV) are hoped to represent more than 50% of worldwide light duty vehicle sales by 2050. The absence of suitable capacitors is one of the major barriers to meeting this goal. Capacitors are a means of storing energy and are vital to the process of converting DC power from the vehicle battery, into AC power required to drive the motor. Current capacitors do not meet the EV requirements, ...

Researchers at NJIT's Big Bear Solar Observatory (BBSO) in Big Bear, CA have obtained new and remarkably detailed photos of the Sun with the New Solar Telescope (NST). The photographs reveal never-before-seen details of solar magnetism revealed in photospheric and chromospheric features. "With our new generation visible imaging spectrometer (VIS)," said Wenda Cao, NJIT Associate Professor of Physics and BBSO Associate Director, "the solar atmosphere from the photosphere to the chromosphere, can be monitored in a near real time. One image was taken with VIS on May ...

A sleepless night makes us more likely to reach for doughnuts or pizza than for whole grains and leafy green vegetables, suggests a new study from UC Berkeley that examines the brain regions that control food choices. The findings shed new light on the link between poor sleep and obesity. Using functional magnetic resonance imaging (fMRI), UC Berkeley researchers scanned the brains of 23 healthy young adults, first after a normal night's sleep and next, after a sleepless night. They found impaired activity in the sleep-deprived brain's frontal lobe, which governs complex ...

Mechanical engineers at the University of California, San Diego invented a robot designed to scoot along utility lines, searching for damage and other problems that require repairs. Made of off-the-shelf electronics and plastic parts printed on an inexpensive 3D printer, the SkySweeper prototype could be scaled up for less than $1,000, making it significantly more economical than the two models of robots currently used to inspect power lines. "Current line inspection robots are large, complex, and expensive. Utility companies may also use manned or unmanned helicopters ...

Researchers at North Carolina State University have created a new flexible nano-scaffold for rechargeable lithium ion batteries that could help make cell phone and electric car batteries last longer. The research, published in Advanced Materials, shows the potential of manufactured sheets of aligned carbon nanotubes coated with silicon, a material with a much higher energy storage capacity than the graphite composites typically used in lithium ion batteries. "Putting silicon into batteries can produce a huge increase in capacity—10 times greater," said Dr. Philip ...

COLUMBUS, Ohio – In a new study, researchers at The Center for Brain and Spinal Cord Repair at The Ohio State University Wexner Medical Center show that is possible to restore immune function in spinal injured mice. People with spinal cord injury often are immune compromised, which makes them more susceptible to infections. Why these people become immune-suppressed is not known, but the Ohio State study found that a disorder called autonomic dysreflexia can cause immune suppression. Autonomic dysreflexia is a potentially dangerous complication of high-level spinal ...

More than 12 billion years ago a star exploded, ripping itself apart and blasting its remains outward in twin jets at nearly the speed of light. At its death it glowed so brightly that it outshone its entire galaxy by a million times. This brilliant flash traveled across space for 12.7 billion years to a planet that hadn't even existed at the time of the explosion - our Earth. By analyzing this light, astronomers learned about a galaxy that was otherwise too small, faint and far away for even the Hubble Space Telescope to see. "This star lived at a very interesting time, ...

A new report from Simon Fraser University researcher Bohdan Nosyk calls for the expansion of heroin and opioid medical treatment to stem the increase of overdose deaths. "Prescription opioid abuse and overdose is on the rise throughout North America," says the SFU Health Sciences associate professor and lead author of the study that was published in Health Affairs. "Opioid overdose is now the second-leading cause of accidental death in the U.S., behind only motor-vehicle accidents. "People from all walks of life, including youths, are accessing these drugs and the ...

Alexandria, VA - Each year, as hurricanes hit U.S. coastlines, scientists study them to improve forecasts critical for saving lives and property. Last year, unmanned aircraft from NASA flew into the biggest storms as part of a project to improve hurricane forecasts by 50 percent over the next 10 years. As EARTH Magazine reports in the August issue, three projects in particular — the Hurricane Forecast Improvement Program, NASA's 2010 Genesis and Rapid Intensification Project Field Experiment and its replacement, the Hurricane and Severe Storm Sentinel Project — may be ...

Frozen sperm taken by biopsy from testicles in men with no sperm in their semen is as effective as fresh sperm taken by biopsy in helping couples conceive through in vitro fertilization (IVF), according to a study at Washington University School of Medicine in St. Louis. The researchers also determined that the type of facility where sperm is taken and its distance from the IVF laboratory has no bearing on pregnancy outcomes. The findings, published online in PLOS ONE, may benefit men with no sperm in their semen due to genetics, cancer diagnoses or testicular failure. ...

New Johns Hopkins research suggests that people who undergo minimally invasive placement of stents to open clogged leg arteries are significantly less likely than those who have conventional bypass surgery to need a second treatment for the condition within two years. For now, bypass surgery remains the gold standard for treating symptoms of peripheral artery disease (PAD), but the Johns Hopkins researchers are hopeful that further study will confirm the advantage their study shows for the stents. The researchers, reporting online in the Journal of Vascular Surgery, ...

More efficient catalytic converters on autos, improved batteries and more sensitive gas sensors are some of the potential benefits of a new system that can directly measure the manner in which nanocrystals adsorb and release hydrogen and other gases. The technique, which was developed by Vanderbilt University Assistant Professor of Chemical and Biomolecular Engineering Rizia Bardhan, is described in a paper published online Aug. 4 by the journal Nature Materials. In the last 30 years, there has been a tremendous amount of research studying nanocrystals – tiny crystals ...

Researchers in the University of Arizona's department of ecology and evolutionary biology have found that despite differences in appearance, trees across species share remarkably similar architecture and can tell scientists a lot about an entire forest. Just by looking at a tree's branching pattern, it turns out, scientists can gather clues about how it functions – for example how much carbon dioxide it exchanges with the atmosphere or how much water transpires through its leaves – regardless of the tree's shape or species. The researchers' results, published in the ...
