Stronger drunk driving laws lead to safer roads: Study

2014-08-18
(Press-News.org) Changes to British Columbia's laws against driving while impaired have reduced fatal crashes as well as ambulance calls and hospital admissions resulting from motor vehicle crashes, a new University of British Columbia study finds.

Researchers concluded that harsher penalties for impaired driving and speeding instituted by the B.C. government in September 2010 reduced crashes related to drinking and driving.

Automobile crashes declined 21 per cent, crash-related hospital admissions dropped 8 per cent and crash-related ambulance calls fell by 7.2 per cent. Based on those statistics, there were an estimated 84 fewer fatal crashes, 308 fewer hospital admissions and 2,553 fewer ambulance calls for road trauma each year.

"Our findings add to the growing evidence that the new laws, although controversial to some, were associated with marked improvements in road safety," said lead author Jeffrey Brubacher, associate professor of Emergency Medicine at UBC, researcher with Vancouver Coastal Health Research Institute and a VCH Emergency Department physician. "We hope that other jurisdictions will follow B.C.'s lead in implementing similar laws designed to deter dangerous driving."

Under the changes B.C. imposed in 2010, first-time offenders with a blood alcohol content (BAC) of .05 per cent to .08 per cent will have their driver's licence suspended for three days, pay a $600 fine and, at police discretion, have their vehicle impounded for three days. Drivers with a BAC higher than .08 per cent face even stiffer penalties.

Previous research by Dr. Brubacher and colleagues found a 40 per cent decrease in alcohol-related fatal crashes and a 23 per cent decrease in alcohol-related injury collisions in the year after the changes took effect.

Drawing on that previous research, the recent study asserts that the changes to the law and accompanying enforcement and media coverage – and not other factors – were responsible for the reduced rate of fatal crashes, hospital admissions and ambulance calls.

INFORMATION: BACKGROUND

Published online Aug. 14 in the American Journal of Public Health, the study notes that there was a drop in fatal crashes in B.C., but there was no decline in fatal crashes in Washington state or Saskatchewan, where laws remained constant during the study period. There was a significant drop in Alberta, but the researchers attribute that to a "spillover" effect of media coverage, and the fact that Alberta began debating and then approved changes similar to B.C.'s during the study period.

HSP72 confers protection in retinal ganglion cells and lateral geniculate nucleus neurons

2014-08-18
Optic nerve transection increased the expression of heat shock protein 72 (HSP72) in the lateral geniculate body, indicating that this protein is involved in the prevention of neuronal injury. Zinc sulfate and quercetin induced and inhibited the expression of HSP72, respectively. In a study reported by Dr. Ning Li and co-workers from the First Affiliated Hospital of Anhui Medical University, China, intraperitoneal injections of zinc sulfate, SP600125 (c-Jun N-terminal kinase inhibitor), or quercetin were performed on retinal ganglion cells in a Wistar rat model of chronic ...

Cholecystokinin octapeptide antagonizes apoptosis in retinal pigment epithelial cells

Cholecystokinin octapeptide antagonizes apoptosis in retinal pigment epithelial cells
2014-08-18
Oxidative stress may cause retinal pigment epithelial (RPE) cell apoptosis. Nitric oxide and superoxide react to produce peroxynitrite, which, along with its derivatives, are strong oxidants. Cholecystokinin octapeptide-8 (CCK-8) can protect cholinergic neurons against basal forebrain lesion caused by brain injury. Research team at Hebei Province People's Hospital, China led by Dr. Yuan Liu treated human RPE cells with the oxidative stress inducer peroxynitrite, and evaluated the neuroprotective effects of CCK-8. Peroxynitrite triggered apoptosis in these cells, and increased ...

New discovery: Microbes create dripstones

New discovery: Microbes create dripstones
2014-08-18
According to new research humble, microscopic organisms can create dripstones in caves. This illustrates how biological life can influence the formation of Earth's geology - and the same may be happening right now on other planets in space. According to traditional textbooks dripstones are created by geological or geochemical processes with no influence from living organisms. But now scientists report that formation of dripstones can be a lot more complex than that: Sometimes microbes are responsible for the formation of these geological features. The researchers from ...

Toothless 'dragon' pterosaurs dominated the Late Cretaceous skies

2014-08-18
A new study provides an exciting insight into the Late Cretaceous and the diversity and distribution of the toothless 'dragon' pterosaurs from the Azhdarchidae family. The research was published in the open access journal ZooKeys. The Azhdarchidan pterosaurs derive their name from the Persian word for dragon - Aždarha. Interestingly, this derived and rather successful group of pterosaurs included some of the largest known flying animals of all times, with a wingspan reaching between 10 and 12 m. 'Dragon' pterosaurs had a worldwide distribution once and were the last ...

CU Denver study shows zoning regulations impact where marijuana dispensaries can locate

2014-08-18
DENVER (August 18, 2014) – Municipal zoning regulations may push marijuana dispensaries into low income, minority areas, according to a study just released by the University of Colorado Denver. Published in the Journal of the American Planning Association, the leading professional and academic planning resource, the study shows that government regulations will likely cause an inequitable distribution of marijuana business throughout the city. Though the impact of dispensaries to the neighborhoods in which they are located has yet to be understood, the research is clear ...

Unraveling the mysteries of the Red Sea: A new reef coral species from Saudi Arabia

Unraveling the mysteries of the Red Sea: A new reef coral species from Saudi Arabia
2014-08-18
The hard corals primarily responsible for the construction of coral reefs around the world have attracted the attention of taxonomists for hundreds of years. Despite the important role such corals play in building what are arguably the world's most diverse ecosystems, coral reefs in some parts of the world still hold surprises for modern scientists. An international team of scientists has recently described a new hard coral species, Pachyseris inattesa, from the Saudi Arabian Red Sea. The study, led by the University of Milano-Biccocain collaboration with the King Abdullah ...

Artificial cells act like the real thing

2014-08-18
Imitation, they say, is the sincerest form of flattery, but mimicking the intricate networks and dynamic interactions that are inherent to living cells is difficult to achieve outside the cell. Now, as published in Science, Weizmann Institute scientists have created an artificial, network-like cell system that is capable of reproducing the dynamic behavior of protein synthesis. This achievement is not only likely to help gain a deeper understanding of basic biological processes, but it may, in the future, pave the way toward controlling the synthesis of both naturally-occurring ...

Upgrading electronic monitoring, downgrading probation

2014-08-18
Under the Coalition Government which came to power in Britain in May 2010, major changes in the community supervision of offenders are underway in England and Wales. Under the new contract for electronic monitoring (EM) (the third since 1999), the government is planning a huge increase in the use of GPS tracking by 2015. Using GPS tracking could well come to be seen as a more reliable and credible way of 'doing' offender management. The government is planning to create the largest and most advanced electronic monitoring (EM) scheme in the world, using combined GPS tracking ...

Poor health literacy poses risks for pacemaker and defibrillator patients

Poor health literacy poses risks for pacemaker and defibrillator patients
2014-08-18
(NEW YORK, NY, August 18, 2014) – Patients who rely on pacemakers and defibrillators to maintain a normal heart rhythm run the risk of serious health complications if they don't fully understand how the devices work and what to do when they experience an irregular heartbeat. But a study from Columbia University School of Nursing published this month in the Journal of Cardiovascular Nursing found that 40 percent of patients with these devices had little to no ability to understand information about their cardiac health. "As a nurse practitioner, I use every patient encounter ...

IU study examines how genes, gender and environment influence substance abuse

IU study examines how genes, gender and environment influence substance abuse
2014-08-18
Social integration, including strong family ties, can protect one's well-being and even reduce the impact high-risk genes have on health. Scientists call this phenomenon a gene-environment interaction. An Indiana University study focusing on substance abuse, however, found that a three-way interplay of gender, genetics and social integration produced the different outcomes for men and women. The study looked at men and women with a genetic sensitivity to stressful situations. Strong family and community ties were protective for such men, reducing their risk of abusing ...
