More opioid dependence treatment needed

2013-08-07
(Press-News.org) 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 consequences are deadly."

The report highlights increases in the prevalence and hazards related to the use of opioids, such as heroin, and prescription opioids like oxycodone, in Canada and the United States, and the gap in treatment availability in both countries.

Evidence shows that methadone and buprenorphine, two forms of opioid substitution therapy, are effective at retaining clients in treatment. Prolonged retention in treatment can lead to reductions in illicit drug use, overdoses, behaviours that increase the risk of contracting HIV, and criminal activity. As a result, treatment has been shown to be highly cost-effective.

The study makes several recommendations to expand access to evidence-based medical treatment, including:

Eliminating restrictions on methadone prescribing Reducing financial barriers to treatment Reducing reliance on opioid detoxification treatment Integrating emerging treatments

There is serious concern for the consequences that may result if effective opioid addiction treatment continues to be limited, says Nosyk, who is also a health economist with the B.C. Centre for Excellence in HIV/AIDS.

"In the absence of readily-available treatment, some of the prescribed opioid users who are becoming dependent will switch from pills to injecting heroin in search of a more potent high," he says.

"This would compound the challenges we have in the fight against HIV/AIDS and Hepatitis C at a time when new technology and treatment options for these conditions are turning the tide."

EARTH: Hurricane hunters fly toward improved storm forecasts

2013-08-07
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 ...

Freezing sperm taken directly from testicles is effective option for infertile couples

2013-08-07
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. ...

Minimally invasive stents show some advantage over bypass in opening blocked leg arteries

2013-08-07
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, ...

Size matters in nanocrystals' ability to adsorb/release gases

2013-08-07
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 ...

One tree's architecture reveals secrets of a forest, study finds

2013-08-07
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 ...

The sun's magnetic field is about to flip

2013-08-07
Something big is about to happen on the sun. According to measurements from NASA-supported observatories, the sun's vast magnetic field is about to flip. "It looks like we're no more than three to four months away from a complete field reversal," said solar physicist Todd Hoeksema of Stanford University. "This change will have ripple effects throughout the solar system." The sun's magnetic field changes polarity approximately every 11 years. It happens at the peak of each solar cycle as the sun's inner magnetic dynamo re-organizes itself. The coming reversal will ...

Protein changes are discovered that control whether a gene functions are discovered

2013-08-07
A Penn State-led research team has found that changes to proteins called histones, which are associated with DNA, can control whether or not a gene is allowed to function. The changes may be important in maintaining the genes' "expression potential" so that future cells behave as their parent cells did. The discovery, which may have implications for the study of diseases such as cancer, will be published in a print edition of the journal Proceedings of the National Academy of Sciences. The research was led by Lu Bai, an assistant professor of biochemistry, molecular biology, ...

New tool helps detect delirium in hospital patients

2013-08-07
UC San Francisco researchers have developed a two-minute assessment tool to help hospital staff predict a patient’s risk of delirium, a change in mental cognition characterized by severe confusion and disorientation that can prolong hospital stays. The condition, which occurs in as many as one in five hospitalized patients, tends to develop rapidly and can lead to higher death rates and increased health care costs. The new tool is designed to be simple, efficient and accurate in helping to assess and treat patients at risk of developing delirium, the scientists ...

Monarch butterflies migration path tracked by generations for first time

2013-08-07
Everyone knows all about the epic breeding journey taken each year by generations of monarch butterflies between Mexico and Canada, right? Not so fast, say researchers including University of Guelph biologists. Until now, linking adult butterflies and their birthplaces during a complicated annual migration spanning all of eastern North America and involving up to five generations of the iconic insects had eluded scientists. Now for the first time, researchers have mapped that migration pattern across the continent over an entire breeding season. That information might ...

Moffitt Cancer Center expert standardizing guidelines for penile cancer treatment

2013-08-07
Penile cancer is rare, with an average of 1,200 new cases per year in the United States, but it can be debilitating and lethal. Without evidenced-based treatment approaches, outcomes have varied widely. Philippe E. Spiess, M.D., an associate member in the Department of Genitourinary Oncology at Moffitt Cancer Center, presented new National Comprehensive Cancer Network Clinical Practice Guidelines in Oncology to standardize care for penile cancer in an article that appeared in the July issue of the Journal of the National Comprehensive Cancer Network. "We wanted to clarify ...
