Phantom limb pain relieved when amputated arm is put back to work

Max Ortiz Catalan, researcher at Chalmers University of Technology, has developed a new method for the treatment of phantom limb pain (PLP) after an amputation. The method is based on a unique combination of several technologies, and has been initially tested on a patient who has suffered from severe phantom limb pain for 48 years. A case study shows a drastic reduction of pain.

Medical homes make small improvement in quality, do not cut costs, study finds

A three-year pilot of a "medical home" model of primary care yielded few improvements in the quality of care and no reductions in hospitalizations, emergency department visits or total costs of care, according to a new RAND Corporation study.

Evaluating one of the nation's earliest and largest multipayer medical home pilots, researchers found that most participating primary care practices achieved recognition as medical homes, but the quality of care improved significantly for only one of 11 widely-used quality measures.

Brain cell activity regulates Alzheimer’s protein

Increased brain cell activity boosts brain fluid levels of a protein linked to Alzheimer's disease, according to new research from scientists at Washington University School of Medicine in St. Louis.

Tau protein is the main component of neurofibrillary tangles, one of the hallmarks of Alzheimer's disease. It has been linked to other neurodegenerative disorders, including frontotemporal dementia, supranuclear palsy and corticobasal degeneration.

Breast-feeding benefits appear to be overstated, according to study of siblings

COLUMBUS, Ohio – A new study comparing siblings who were fed differently during infancy suggests that breast-feeding might be no more beneficial than bottle-feeding for 10 of 11 long-term health and well-being outcomes in children age 4 to 14.

The outlier was asthma, which was associated more with breast-feeding than with bottle-feeding.

Can babies learn to read? No, NYU study finds

Can babies learn to read? While parents use DVDs and other media in an attempt to teach their infants to read, these tools don't instill reading skills in babies, a study by researchers at New York University's Steinhardt School of Culture, Education, and Human Development has found.

Study uncovers why almost winning is just as good for some gamblers

A new study led by the University of Exeter and Swansea University has pinpointed the changes in the brain that lead gamblers to react in the same way to near-misses as they do to winning.

The research shows that near-misses are underpinned by increases in the brain's electrical activity, particularly in the theta frequency range - known to be involved in processing win and loss outcomes.

They found that these increases in theta are linked to both how severe someone's gambling history is and how susceptible they might be to developing a future gambling problem.

Analysis: 32 years of US filicide arrests

PROVIDENCE, R.I. [Brown University] — Instances in which parents kill their children may seem so horrifying and tragic that they defy explanation. Published scientific and medical research, meanwhile, doesn't offer much epidemiological context to help people understand patterns among such heinous crimes. A paper in the March edition of the journal Forensic Science International provides the first comprehensive statistical analysis of filicide in the United States, drawing on 32 years of data on more than 94,000 arrests.

Psychological side-effects of anti-depressants worse than thought

LIVERPOOL, UK – 26 February 2014: A University of Liverpool researcher has shown that thoughts of suicide, sexual difficulties and emotional numbness as a result of anti-depressants may be more widespread than previously thought.

In a survey of 1,829 people who had been prescribed anti-depressants, the researchers found large numbers of people – over half in some cases – reporting on psychological problems due to their medication, which has led to growing concerns about the scale of the problem of over-prescription of these drugs.

Researchers generate new neurons in brains, spinal cords of living adult mammals

DALLAS, Feb. 25, 2014 – UT Southwestern Medical Center researchers created new nerve cells in the brains and spinal cords of living mammals without the need for stem cell transplants to replenish lost cells.

Vascular disease affecting women 'poorly understood' by many health care providers

MAYWOOD, IL – A vascular disease called fibromuscular dysplasia, which can cause high blood pressure, kidney failure, stroke and other symptoms -- mostly in women -- is "poorly understood by many healthcare providers," according to a Scientific Statement from the American Heart Association.

Neurologist Jose Biller, MD, of Loyola University Medical Center, is a co-author of the statement, published online ahead of print in the American Heart Association journal Circulation. First author is Jeffrey W. Olin, DO of Mount Sinai School of Medicine.

Mood and food: The better your mood, the better you eat

Previous research has found that emotions affect eating, and that negative moods and positive moods may actually lead to preferences for different kinds of foods. For example, if given the choice between grapes or chocolate candies, someone in a good mood may choose the former while someone in a bad mood may choose the latter. The research reported in this article looks at the "why:" Why, when someone is in a bad mood, will they choose to eat junk food and why, when someone is in a good mood, will they make healthier food choices?

Tumors 'light up' with new, unique imaging system using scorpion venom protein and a laser

LOS ANGELES (Feb. 24, 2014) – Researchers at the Cedars-Sinai Maxine Dunitz Neurosurgical Institute and Department of Neurosurgery have developed a unique, compact, relatively inexpensive imaging device to "light up" malignant brain tumors and other cancers.

Study shows mentally ill more likely to be victims, not perpetrators, of violence

New research shows that almost one-third of adults with mental illness are likely to be victims of violence within a six-month period, and that adults with mental illness who commit violence are most likely to do so in residential settings. The study also finds a strong correlation between being a victim of violence and committing a violent act.

The work was done by researchers at North Carolina State University; RTI International; the University of California, Davis; Simon Fraser University; and Duke University.

Anti-vaccine conspiracy theories may have 'detrimental consequences' for children's health

A belief in anti-vaccine conspiracy theories may have significant and detrimental consequences for children's health, new research from the University of Kent has shown.

Researchers Daniel Jolley and Dr Karen Douglas, of the University's School of Psychology, surveyed 89 parents about their views on anti-vaccine conspiracy theories and then asked them to indicate their intention to have a fictional child vaccinated. It was found that stronger belief in anti-vaccine conspiracy theories was associated with lower intention to vaccinate.

Guideline: People with irregular heartbeat should take blood thinners to prevent stroke

MINNEAPOLIS – An updated guideline from the American Academy of Neurology recommends that people with nonvalvular atrial fibrillation, or irregular heartbeat, take oral anticoagulants, a type of blood thinner pill, to prevent stroke. The guideline is published in the February 25, 2014, print issue of Neurology®, the medical journal of the American Academy of Neurology. The World Stroke Organization has endorsed the updated guideline.
