Nalmefene for alcohol dependence: Added benefit not proven Posted: 04 Dec 2014 07:31 AM PST No added benefit can be derived from the indirect comparison presented in the drug manufacturer dossier, in particular because the studies on the appropriate comparator therapy were unsuitable, scientists say.

Vaccination remains the best way to avoid the flu Posted: 04 Dec 2014 07:29 AM PST Joy and goodwill aren't the only things we start spreading to friends, family, colleagues -- even strangers -- this time of year. Late fall and early winter also signal the start of annual spread of the influenza virus.

Don’t worry, be happy: Just go to bed earlier Posted: 04 Dec 2014 06:11 AM PST Researchers link late evenings to repetitive negative thoughts. When you go to bed, and how long you sleep at a time, might actually make it difficult for you to stop worrying. So say researchers, who found that people who sleep for shorter periods of time and go to bed very late at night are often overwhelmed with more negative thoughts than those who keep more regular sleeping hours.

New model to detect aggressive driving Posted: 04 Dec 2014 06:11 AM PST Researchers have developed a system capable of detecting patterns of reckless driving behavior with non intrusive methods for the driver.

Milestones in human-machine cooperation Posted: 04 Dec 2014 06:11 AM PST Major technical progress has been made on several fronts with the Robo-Mate exoskeleton. A key focus of the initial twelve months of the Robo-Mate project was to define the various production processes of end-users from different industries (e.g. automotive, automotive components, dismantling, and scrap recycling).

Strong neighborhoods, parenting can bridge 'achievement gap' Posted: 04 Dec 2014 06:09 AM PST A study of academic achievement suggests that urban youth may benefit from strong families and safe neighborhoods in addition to child-centered interventions. The study aimed to learn what factors influence how young people develop their future aspirations -- and how those aspirations shape their experiences at school.

Cancer from asbestos caused by more than one cell mutation Posted: 04 Dec 2014 04:43 AM PST It has been a long held belief that tumors arising from exposure to asbestos are caused by mutations in one cell, which then produces multiple clones. This hypothesis is challenged by new research, which suggests it is caused by mutations in multiple cells.

Medications for patients with first episode psychosis may not meet guidelines Posted: 04 Dec 2014 04:43 AM PST Many patients with first-episode psychosis receive medications that do not comply with recommended guidelines for first-episode treatment, researchers have found. Current guidelines emphasize low doses of antipsychotic drugs and strategies for minimizing the side effects that might contribute to patients stopping their medication. A NIH-funded study finds that almost 40 percent of people with first-episode psychosis in community mental health clinics across the country might benefit from medication treatment changes.

Parkinson's drugs safe for the heart, preliminary study suggests Posted: 04 Dec 2014 04:43 AM PST Non-ergot derived dopamine agonists used to treat Parkinson's disease may be safe for the heart, according to preliminary research.

Current guidelines not clear on which children most at risk of severe flu complications Posted: 04 Dec 2014 04:41 AM PST Children born prematurely are at an increased risk of flu-related complications, despite not being identified as an "at risk" group in UK, USA, or WHO guidelines, and should be a priority group for the seasonal flu vaccination, new research suggests.

Psychological problems in men experiencing cancer Posted: 04 Dec 2014 04:41 AM PST Some key markers for vulnerability to psychological problems in men experiencing cancer have been identified by researchers. A group of 127 men aged 18 and over with a cancer diagnosis were recruited through the National Health Service in England and cancer charities between April 2009 and April 2011. The participants were assessed for demographic factors, social support, anxiety and depression, and distress. The findings indicated that participants who were separated and divorced had lower social support and greater depression. Younger age was related to higher anxiety, and distress. Living in an area of higher deprivation indicated greater depression and anxiety. Social support was also a key indicator of psychological health.

What really helps women achieve a good work-life balance? Posted: 04 Dec 2014 04:41 AM PST "Women continue to be underrepresented in organizational life, in professions such as surgery and in roles such as leadership. This lack of representation is both a moral issue of gender inequality and a practical issue of productivity and staff retention," an expert outlines. She uncovered the phenomenon of the glass cliff, whereby women (and members of other minority groups) are more likely to be placed in leadership positions which are risky or precarious

Uncovering one of humankind’s most ancient lineages Posted: 04 Dec 2014 04:41 AM PST Scientists have successfully discovered one of modern human's ancient lineages through the sequencing of genes.  This is the first time that the history of humankind populations has been analysed and matched to Earth's climatic conditions over the last 200,000 years.

3-D printing to the rescue of gastronomy for frail seniors Posted: 04 Dec 2014 04:40 AM PST Researchers are now developing personalised food for elderly people with chewing or swallowing problems, by working on printable versions of meat and vegetables.

More evidence for impact of lung cancer targeted therapy from practice-changing trial Posted: 04 Dec 2014 04:40 AM PST For previously untreated lung cancer patients with a particular genetic change, a new targeted therapy is better than standard chemotherapy, a new study confirms. This work involved 343 patients with previously untreated ALK-positive advanced non-small cell lung cancer. It showed that those patients who received crizotinib did better with respect to improvement in symptoms and delay in growth of the cancer than those on standard chemotherapy. Also the new targeted drug had no unexpected side effects.

Natural substance in red wine has an anti-inflammatory effect in cardiovascular diseases Posted: 04 Dec 2014 04:40 AM PST A natural substance present in red wine, resveratrol, inhibits the formation of inflammatory factors that trigger cardiovascular diseases, a research team concludes. They report that resveratrol binds with the KSRP regulator protein and provides for its activation.

Mini chromosomes that strengthen tumors Posted: 04 Dec 2014 04:40 AM PST Cancers are due to genetic aberrations in certain cells that gain the ability to divide indefinitely. This proliferation of sick cells generates tumors, which gradually invade healthy tissue. Therefore, current therapies essentially seek to destroy cancer cells to stop their proliferation. Through high-throughput genetic sequencing of glioblastoma cells, one of the most deadly brain tumors, a team of geneticists has discovered that some of these mutations are caused by supplemental extrachromosomal DNA fragments, called double minutes, which enable cancer cells to better adapt to their environment and therefore better resist to treatments meant to destroy them.

Technology breakthrough reveals cellular transcription process Posted: 04 Dec 2014 04:38 AM PST A new technology that reveals cellular gene transcription in greater detail has been developed by researchers. "This new research tool offers us a more profound view of the immune responses that are involved in a range of diseases, such as HIV infection. At the level of gene transcription, this had been difficult, complex and costly to do with current technologies, such as microscopy," a researcher said.
