Training bystanders to spot drug overdoses can reduce deaths

Educational program key to addressing the epidemic of opioid overdoses

2013-02-01
(Press-News.org) Overdoses of opioid drugs are a major cause of emergency hospital admissions and preventable death in many countries. In Massachusetts, annual opioid-related overdose deaths have exceeded motor vehicle deaths since 2005, so several strategies have been introduced to tackle this growing problem.

For example, overdose education and naloxone distribution (OEND) programs train drug users, their families and friends, and potential bystanders to prevent, recognize, and respond to opioid overdoses. OEND participants are trained to recognize signs of overdose, seek help, rescue breathe, use naloxone (a drug that reverses the effects of opioid overdose), and stay with victims.

From 1996 to 2010, over 50,000 potential bystanders were trained by OEND programs in the United States, resulting in over 10,000 opioid overdose rescues, but their impact on death rates and hospital use has not been examined in controlled studies.

A team of researchers from Boston Medical Center (BMC), Boston University Schools of Medicine (BUSM) and Public Health (BUSPH) in collaboration with the Massachusetts Department of Public Health (MDPH), set out to evaluate the impact of OEND programs between 2006 and 2009.

They analysed annual opioid-related overdose deaths, emergency department and acute hospital use from 2002 to 2009 in 19 Massachusetts communities with high levels of opioid overdose where there was no, low and high OEND implementation.

After adjusting for factors such as age, sex, ethnicity, poverty, "doctor shopping" for prescription opioids, and addiction treatment, they found a significant reduction in opioid-related overdose deaths in communities where OEND was implemented compared with those where it was not. There appeared to be a dose-related impact, where the higher the cumulative rate of OEND implementation, the greater the reduction in death rates.

However, no significant differences in emergency department and acute hospital use were found. This, say the authors may be because the program encourages bystanders to engage the emergency medical system if they suspect an overdose.

"This study provides observational evidence that by training potential bystanders to prevent, recognize, and respond to opioid overdoses, OEND is an effective public intervention," they conclude.

Medical school gift restriction policies linked to subsequent prescribing behavior

2013-02-01
Medical school policies that restrict gifts to physicians from the pharmaceutical and device industries are becoming increasingly common, but the effect of such policies on physician prescribing behaviour after graduation into clinical practice is unknown. So a team of US researchers set out to examine whether attending a medical school with a gift restriction policy affected subsequent prescribing of three newly marketed psychotropic (stimulant, antidepressant, and antipsychotic) drugs. They identified 14 US medical schools with an active gift restriction policy ...

Planting trees may not reverse climate change but it will help locally

Planting trees may not reverse climate change but it will help locally
2013-02-01
Afforestation, planting trees in an area where there have previously been no trees, can reduce the effect of climate change by cooling temperate regions finds a study in BioMed Central's open access journal Carbon Balance and Management. Afforestation would lead to cooler and wetter summers by the end of this century. Without check climate change is projected to lead to summer droughts and winter floods across Europe. Using REMO, the regional climate model of the Max Planck Institute for Meteorology, researchers tested what would happen to climate change in 100 years ...

New stroke gene discovery could lead to tailored treatments

2013-02-01
An international study led by King's College London has identified a new genetic variant associated with stroke. By exploring the genetic variants linked with blood clotting – a process that can lead to a stroke – scientists have discovered a gene which is associated with large vessel and cardioembolic stroke but has no connection to small vessel stroke. Published in the journal Annals of Neurology, the study provides a potential new target for treatment and highlights genetic differences between different types of stroke, demonstrating the need for tailored treatments. ...

2013-02-01
The scientists, from Imperial College London, say their research brings them another step closer to a new kind of industrial revolution, where parts for these biological factories could be mass-produced. These factories have a wealth of applications including better drug delivery treatments for patients, enhancements in the way that minerals are mined from deep underground and advances in the production of biofuels. Professor Paul Freemont, Co- Director of the Centre for Synthetic Biology and Innovation at Imperial College London and principle co-investigator of the study, ...

The genome of rock pigeon reveals the origin of pigeons and the molecular traits

2013-02-01
January 31, 2013, Shenzhen, China – In a study published today in Science, researchers from University of Utah, BGI, and other institutes have completed the genome sequencing of rock pigeon, Columba livia, among the most common and varied bird species on Earth. The work reveals the evolutionary secrets of pigeons and opens a new way for researchers to study the genetic traits controlling pigeons' splendid diversity. The findings also help to fill the genetic gaps in exploiting pigeon as a model for the molecular genetic basis of avian variation. People are quite familiar ...

Placental blood flow can influence malaria during pregnancy

Placental blood flow can influence malaria during pregnancy
2013-02-01
Malaria in pregnancy causes a range of adverse effects, including abortions, stillbirths, premature delivery and low infant birth weight. Many of these effects are thought to derive from a placental inflammatory response resulting from interaction of infected red blood cells with the placental tissue. In a study published in the latest issue of the journal PLOS Pathogen*, a researchers' team led by Carlos Penha-Gonçalves at the Instituto Gulbenkian de Ciência (IGC), Portugal, observed, for the first time, the mouse placental circulation and showed how it can influence the ...

Sequencing hundreds of chloroplast genomes now possible

2013-02-01
Researchers at the University of Florida and Oberlin College have developed a sequencing method that will allow potentially hundreds of plant chloroplast genomes to be sequenced at once, facilitating studies of molecular biology and evolution in plants. The chloroplast is the compartment within the plant cell that is responsible for photosynthesis and hence provides all of the sugar that a plant needs to grow and survive. The chloroplast is unusual in containing its own DNA genome, separate from the larger and dominant genome that is located in every cell's nucleus. ...

Examining the so-called Basque mutation of Parkinson's

Examining the so-called Basque mutation of Parkinsons
2013-02-01
This press release is available in Spanish. The relationship between genetics and Parkinson's has been investigated for more than a decade, but it is only over the last few years that significant results have begun to be obtained. The first mutations related to the development of this disease were found in 2004. A team from the UPV/EHU-University of the Basque Country came across a mutation of the LRRK2 gene, which is particularly prevalent among the population of Gipuzkoa. It is the R1441G mutation and is known as the Basque mutation. Now, Doctor Javier Ruiz, a doctor ...

NASA sees a coronal mass ejection erupt from the sun

NASA sees a coronal mass ejection erupt from the sun
2013-02-01
On Jan. 31, 2013 at 2:09am EST, the sun erupted with an Earth-directed coronal mass ejection or CME. Experimental NASA research models, based on observations from the Solar Terrestrial Relations Observatory (STEREO) and ESA/NASA's Solar and Heliospheric Observatory, show that the CME left the sun at speeds of around 575 miles per second, which is a fairly typical speed for CMEs. Historically, CMEs at this speed are mild. Not to be confused with a solar flare, a CME is a solar phenomenon that can send solar particles into space and reach Earth one to three days later. Earth-directed ...

The effective collective: Grouping could ensure animals find their way in a changing environment

2013-02-01
For social animals such as schooling fish, the loss of their numbers to human activity could eventually threaten entire populations, according to a finding that such animals rely heavily on grouping to effectively navigate their environment. Princeton University researchers report in the journal Science that collective intelligence is vital to certain animals' ability to evaluate and respond to their environment. Conducted on fish, the research demonstrated that small groups and individuals become disoriented in complex, changing environments. However, as group size is ...
