Weather changes may be linked to stroke hospitalizations

Stroke hospitalization rates appear to rise and fall with sharp changes in outdoor temperature and dew point, a pilot study led by the Yale School of Public Health has found. The research, presented this week at the American Stroke Association’s International Stroke Conference 2014, shows an association of stroke hospitalizations with exposure to extreme daily temperature and dew point fluctuations.

The study examined Medicare, Medicaid, and private insurance data from hospitals across the United States. The researchers looked at 157,130 hospital discharges in 2010-2011 for ischemic stroke (caused by a blood clot that blocks blood flow in or leading to the brain). The researchers also obtained temperature and dew point data during the same period and localized it to the county level. (more…)

Help for a scarred heart: Scarring cells turned to beating muscle

Poets and physicians know that a scarred heart cannot beat the way it used to, but the science of reprogramming cells offers hope—for the physical heart, at least.

A team of University of Michigan biomedical engineers has turned cells common in scar tissue into colonies of beating heart cells. Their findings could advance the path toward regenerating tissue that’s been damaged in a heart attack. (more…)

Im Schlaf gemeinsam Gutes tun

Samsung Österreich und die Fakultät für Lebenswissenschaften der Universität Wien haben heute den Startschuss für eine großangelegte nationale Initiative gegeben: Unter dem Namen “Power Sleep” wollen die beiden Partner Smartphone- und Tablet-User in ganz Österreich dazu anregen, die Forschung im Kampf gegen Krankheiten wie Alzheimer oder Krebs voranzutreiben. Erreicht werden soll dies über eine eigens entwickelte Android-App: Sie erlaubt die nicht benötigte Prozessorleistung der mobilen Endgeräte der wissenschaftlichen Forschung zu spenden – etwa während man schläft.

“Technologie kann nur in den Händen der Menschen Großes vollbringen. Was Thomas Rattei und sein Team an der Universität Wien in der Proteinforschung mit IT-Unterstützung und wissenschaftlichem Know-how leisten, hat uns inspiriert. Unsere Anerkennung dafür – und gleichzeitig unser Beitrag für den Kampf gegen Alzheimer oder Krebs – heißt Power Sleep”, erklärt Martin Wallner, Senior Director IT & Mobile bei Samsung Electronics Austria.

Researchers find brain’s ‘sweet spot’ for love in neurological patient

A region deep inside the brain controls how quickly people make decisions about love, according to new research at the University of Chicago.

The finding, made in an examination of a 48-year-old man who suffered a stroke, provides the first causal clinical evidence that an area of the brain called the anterior insula “plays an instrumental role in love,” said UChicago neuroscientist Stephanie Cacioppo, lead author of the study. (more…)

Bipolar patients have high Rx burden

A new study of patients with bipolar disorder finds that 36 percent of those who were admitted to a Rhode Island psychiatric hospital in 2010 were receiving “complex polypharmacy” — four or more psychotropic medications — from their community providers. The polypharmacy rate was significantly higher for women. Including prescriptions for other conditions the patients may have had, the average patient was on six medications. (more…)

Researchers ID more pesticides linked to Parkinson’s, gene that increases risk

Studies have shown that certain pesticides can increase people’s risk of developing Parkinson’s disease. Now, UCLA researchers have found that the strength of that risk depends on an individual’s genetic makeup, which, in the most pesticide-exposed populations, could increase a person’s chance of developing the debilitating disease two- to six-fold.

In an earlier study, published January 2013 in Proceedings of the National Academy of Sciences, the UCLA team discovered a link between Parkinson’s and the pesticide benomyl, a fungicide that has been banned by the U.S. Environmental Protection Agency. That study found that benomyl prevents the enzyme aldehyde dehydrogenase (ALDH) from converting aldehydes — organic compounds that are highly toxic to dopamine cells in the brain — into less toxic agents, thereby contributing to the risk of Parkinson’s.

Decoding dengue and West Nile: Researchers take steps toward control of growing public health problems

ANN ARBOR — Dengue fever and West Nile fever are mosquito-borne diseases that affect hundreds of millions of people worldwide each year, but there is no vaccine against either of the related viruses.

A team of scientists at the University of Michigan and Purdue University has discovered a key aspect both to how the viruses replicate in the cells of their host and how they manipulate the immune system as they spread. (more…)
