Drinking age laws have a significant effect on collisions among young drivers
2014-11-19
(Press-News.org) Minimum legal drinking age legislation in Canada can have a major impact on young drivers, according to a new study from the Northern Medical Program at the University of Northern British Columbia (UNBC). Drivers just older than the legal age had a significant increase in motor vehicle crashes compared to those immediately under the restriction.
In the study, published this week in the American Journal of Preventive Medicine, Dr. Russ Callaghan and his research team looked at Quebec motor vehicle collision statistics between 2000 and 2012 which involved young drivers. They found that, compared to those just below legal age, there was an abrupt increase of 6 per cent in collisions for drivers at or above the minimum legal drinking age (MLDA). This increase was even more marked at night when collisions increased by 11 per cent immediately at the minimum legal drinking age.
"As soon as youth are given legal access to alcohol, there are immediate effects on the road," says Dr. Callaghan, the study`s lead author and an associate professor in the Northern Medical Program. "The number of collisions involving both male and female drivers who have just reached legal drinking age rises dramatically, which illustrates the impact that alcohol-related legislation can have on population harm and injury prevention."
At present time, the minimum legal drinking age is 18 years of age in Alberta, Manitoba, and Québec, and 19 years in the rest of Canada. Recently, the Canadian Public Health Association and a national expert-panel working group have recommended that the legal drinking age be raised to 19 years across the country.
"Our research provides current information for both Canadian and international policymakers to draw on when considering alcohol policy reform and the effectiveness of MLDA legislation," says Callaghan. "Drinking-age laws can have major consequences on driving safety and are an important part of contemporary alcohol-control and driving-related policies designed to limit the motor vehicle collisions in youth."
According to the research, raising the drinking age to 19 years in Québec would prevent 337 police-reported collisions per year that involved at least one 18-year old driver. If it were raised to 21 years, it could be expected that approximately 583 police-reported collisions per year could be prevented for drivers between 18 and 20 years of age.
Dr. Callaghan's research is part of a larger series of studies he is pursuing over the next several years that investigate the impact of alcohol-related legislation on a variety of harms, including mortality, hospital emergency admissions, in-patient admissions, injury, and crimes, such as sexual assaults and disorderly conduct.

A physicist in Syracuse University's College of Arts and Sciences is the lead contributor to the discovery of two never-before-seen baryonic particles. The finding, which is the subject of a forthcoming article in Physical Review Letters (American Physical Society, 2014), is expected to have a major impact on the study of quark dynamics.
Steven Blusk, associate professor of physics, has identified particles known as Xi_b'- and Xi_b*-. Although the particles had been predicted to exist, nobody has seen them until now. The discovery is part of his ongoing work at the Large ...

The first issue of a new publication series from The Gerontological Society of America (GSA) called From Policy to Practice explores pain as a public health problem and takes a look at how various policies impact the care provided to patients in a range of practice settings. It also provides readers with an overview of provisions of the Affordable Care Act that address pain research, education, training, and clinical care -- as well as steps taken to implement those provisions.

Physician-researchers from the Cardiac Center at The Children's Hospital of Philadelphia (CHOP) presented new findings on pediatric cardiovascular disease at the American Heart Association's Scientific Sessions 2014 in Chicago. Among many other topics, they investigated using automated external defibrillators in infants, long-term cardiac risk in surgical survivors of the Fontan operations for congenital heart disease, and whether centers that perform more cardiac catheterizations tend to have better outcomes.

Peruvian coastal waters may provide suitable habitat that may help the recovery of endangered South Pacific green turtles, according to a study published November 19, 2014 in the open-access journal PLOS ONE by Ximena Velez-Zuazo from University of Puerto Rico and colleagues.
Green turtles inhabit tropical and subtropical coastal waters around the world. The authors of this study worked to identify suitable habitat for the endangered species by measuring two populations off the Peruvian coast from 2010 to 2013 in potentially important feeding grounds.

Florida harvester ants move and construct a similar subterranean nest about once a year, according to a study published November 19, 2014 in the open-access journal PLOS ONE by Walter Tschinkel from Florida State University.
The Florida harvester ant excavates up to 2 meter deep nests in the sandy soils of the Gulf and Atlantic coastal plains. Scientists tracked and mapped nest relocations of over 400 colonies in a north Florida coastal plains pine forest from 2010 to 2013 and monitored the progress of entire relocations of 20 of these nests.
The researchers found that ...

A new study in mice, conducted by researchers at Sweden's Karolinska Institutet together with colleagues in Singapore and the United States, shows that our natural gut-residing microbes can influence the integrity of the blood-brain barrier, which protects the brain from harmful substances in the blood. According to the authors, the findings provide experimental evidence that our indigenous microbes contribute to the mechanism that closes the blood-brain barrier before birth. The results also support previous observations that gut microbiota can impact brain development ...

LA JOLLA--Scientists at the Salk Institute have discovered a powerful one-two punch for countering a common genetic mutation that often leads to drug-resistant cancers. The dual-drug therapy--with analogs already in use for other diseases--doubled the survival rate of mice with lung cancer and halted cancer in pancreatic cells.
Lung cancer, which affects nonsmokers as well as smokers, is the most common cancer worldwide, causing 1.6 million deaths a year, far more than pancreatic, breast and colon cancer combined. About 30 percent of the most common type of lung cancer ...

WASHINGTON, D.C. - An antidepressant commonly prescribed for women with postpartum depression may restore connections between cells in brain regions that are negatively affected by chronic stress during pregnancy, new research suggests.
Ohio State University scientists found that rats that had been chronically stressed during pregnancy showed depressive-like behaviors after giving birth, and structures in certain areas of their brains were less complex than in unstressed rats. After receiving the drug for three weeks, these rats had no depressive symptoms and neurons ...
