(Press-News.org) "Traumatic brain injury (TBI) is a major cause of hospitalization, disability, and death-worldwide, and among older adults, falling is the most common cause of TBI," writes Niina Korhonen, B.M., of the Injury and Osteoporosis Research Center, Tampere, Finland, and colleagues in a Research Letter. The authors previously reported that the number and incidence of adults 80 years of age or older admitted to the hospital due to fall-induced TBI in Finland increased from 1970 through 1999. This analysis is a follow-up of this population through 2011.
The study included data from the Finnish National Hospital Discharge Register, a nationwide, computer-based register that provides data for severe injuries among the Finnish population. The researchers found that the total number of older Finnish adults with a fall-induced TBI increased considerably from 60 women and 25 men in 1970 to 1,205 women and 612 men in 2011. The age-adjusted incidence of TBI (per 100,000 persons) also showed an increase from 168.2 women in 1970 to 653.6 in 2011 (an increase of 289 percent) and from 174.6 to 724.0, respectively, in men (an increase of 315 percent).
"Our 40-year follow-up shows that the number and age-adjusted incidence of fall-induced TBI in Finnish men and women aged 80 years or older increased considerably between 1970 and 2011. Compared with the data in our previous study, the increase has continued since 1999," the authors write. "Further studies are needed to better understand the reasons for the increase in fall-related TBI in older persons (aged >80 years) so that effective interventions for falls and injury prevention can be initiated."

Theta brainwaves reflect ability to beat built-in bias
2013-05-08
PROVIDENCE, R.I. [Brown University] — Vertebrates are predisposed to act to gain rewards, and to lay low to avoid punishment. Try to teach chickens to back away from food in order to obtain it, and you'll fail, as researchers did in 1986. But (some) humans are better thinkers than chickens. In the May 8 edition of the Journal of Neuroscience, researchers show that the level of theta brainwave activity in the prefrontal cortex predicts whether people will be able to overcome these ingrained biases when doing so is required to achieve a goal.
The study helps explain a distinctly ...
Rats take high-speed multisensory snapshots
2013-05-08
Cold Spring Harbor, N.Y. – When animals are on the hunt for food they likely use many senses, and scientists have wondered how the different senses work together.
New research from the laboratory of CSHL neuroscientist and Assistant Professor Adam Kepecs shows that when rats actively use the senses of smell (sniffing) and touch (through their whiskers) those two processes are locked in synchronicity. The team's paper, published today in the Journal of Neuroscience, shows that sniffing and "whisking" movements are synchronized even when they are running at different frequencies.

In Cleveland Clinic study, less than half of deaths after angioplasty result of procedure
2013-05-08
Cleveland: Only 42 percent of the deaths occurring within 30 days of percutaneous coronary interventions (PCI) were attributable to complications from the procedure, according to a Cleveland Clinic study published online in the Journal of the American College of Cardiology. The research suggests alternative outcome reporting mechanisms for 30-day mortality for PCI should be considered before mandatory reporting regulations are put into place.
PCI is a non-surgical procedure in which balloons and/or stents are used to open blocked or narrowed arteries, which are typically ...
Sunshine could benefit health and prolong life, study suggests
2013-05-08
Exposing skin to sunlight may help to reduce blood pressure, cut the risk of heart attack and stroke – and even prolong life, a study suggests.
Researchers have shown that when our skin is exposed to the sun's rays, a compound is released in our blood vessels that helps lower blood pressure.
The findings suggest that exposure to sunlight improves health overall, because the benefits of reducing blood pressure far outweigh the risk of developing skin cancer.
The study has been carried out by the University of Edinburgh.
Heart disease and stroke linked to high ...
Women with unintended pregnancy are more likely to suffer from postpartum depression
2013-05-08
Women with unintended pregnancy are four times more likely to suffer from postpartum depression at twelve months postpartum, suggests a new study published today (8 May) in BJOG: An International Journal of Obstetrics and Gynaecology.
The study, conducted at the University of North Carolina prenatal clinics questioned participants about pregnancy intention at 15-19 weeks gestational age, and women were classified as having an intended, mistimed or unwanted pregnancy. There were 433 women (64%) with an intended pregnancy, 207 (30%) with a mistimed pregnancy and 40 (6%) ...
Twitter analysis shows Boston bombings had little effect on immigration reform conversations
2013-05-08
An analysis by researchers at the Institute for Immigration Research (IIR) at George Mason University shows that the Boston Marathon bombings had little effect on conversations on social media regarding immigration reform.
Using two different data mining applications, the researchers collected more than 750,000 tweets containing the word "immigration" beginning in February 2013.
"The Boston Marathon bombings on April 15, 2013 provided an unexpected opportunity to examine how this event has affected the immigration reform debate," says Jim Witte, director of the IIR. ...
AFOSR-funded research key to revolutionary 'green' spacecraft propellant
2013-05-08
In 2015, NASA, for the first time, will fly a space mission utilizing a radically different propellant—one which has reduced toxicity and is environmentally benign. This energetic ionic liquid, or EIL, is quite different from the historically employed hydrazine-based propellant, which was first used as a rocket fuel during World War II for the Messerschmitt Me 163B (the first rocket-powered fighter plane).
Within the U.S. space program, hydrazine was used on the 1970s Viking Mars program, and more recently in the Phoenix lander and Curiosity rover Mars missions, as ...

Duke researchers describe how breast cancer cells acquire drug resistance
2013-05-08
DURHAM, N.C. -- A seven-year quest to understand how breast cancer cells resist treatment with the targeted therapy lapatinib has revealed a previously unknown molecular network that regulates cell death. The discovery provides new avenues to overcome drug resistance, according to researchers at Duke Cancer Institute.
"We've revealed multiple new signaling pathways that regulate cell death," said Sally Kornbluth, PhD, vice dean of Basic Science and professor of Pharmacology and Cancer Biology at Duke University School of Medicine. "And we've shown, at least in one disease, ...
Turning Alzheimer's fuzzy signals into high definition
2013-05-08
Scientists at the Virginia Tech Carilion Research Institute have discovered how the predominant class of Alzheimer's pharmaceuticals might sharpen the brain's performance
One factor even more important than the size of a television screen is the quality of the signal it displays. Having a life-sized projection of Harry Potter dodging a Bludger in a Quidditch match is of little use if the details are lost to pixilation.
The importance of transmitting clear signals, however, is not relegated to the airwaves. The same creed applies to the electrical impulses navigating ...
