Keep Calm, Anger Can Trigger A Heart Attack!

University of Sydney research reveals that the risk of a heart attack is 8.5 times higher in the two hours following a burst of intense anger.

Published in European Heart Journal: Acute Cardiovascular Care, this is the first Australian study to investigate the link between acute emotional triggers and high risk of severe cardiac episodes.

“Our findings confirm what has been suggested in prior studies and anecdotal evidence, even in films — that episodes of intense anger can act as a trigger for a heart attack,” said lead author Dr Thomas Buckley, Sydney Nursing School, University of Sydney, and researcher at Royal North Shore Hospital.

Quick Test For Ebola Developed

When diagnosing a case of Ebola, time is of the essence. However, existing diagnostic tests take at least a day or two to yield results, preventing health care workers from quickly determining whether a patient needs immediate treatment and isolation.

A new test from MIT researchers could change that: The device, a simple paper strip similar to a pregnancy test, can rapidly diagnose Ebola, as well as other viral hemorrhagic fevers such as yellow fever and dengue fever.

“As we saw with the recent Ebola outbreak, sometimes people present with symptoms and it’s not clear what they have,” says Kimberly Hamad-Schifferli, a visiting scientist in MIT’s Department of Mechanical Engineering and a member of the technical staff at MIT’s Lincoln Laboratory. “We wanted to come up with a rapid diagnostic that could differentiate between different diseases.”

Teen Girls From Rural Areas More Likely To Have Undiagnosed Asthma, Be Depressed

Teen girls who live in rural areas are more likely than their male counterparts to have undiagnosed asthma, and they often are at a higher risk of depression, according to researchers at the Medical College of Georgia at Georgia Regents University.

According to data collected during a three-year trial of an asthma program tailored to teens, the prevalence of asthma — both diagnosed and undiagnosed — was about the same in rural areas as it is in urban settings. But more girls had undiagnosed asthma than boys.

“There’s a lot of speculation about why females are more likely to be undiagnosed,” says Dr. Jeana Bush, an MCG Allergy and Immunology Fellow. “Maybe it’s because boys are more likely to get a sports physical for athletics and they catch it then. Or maybe it’s because girls attribute asthma symptoms to something else, like anxiety.

Polio Vaccination With Microneedle Patches Receives Funding For Patch Development, Clinical Trial

The Georgia Institute of Technology and Micron Biomedical have been awarded $2.5 million in grants from the Bill & Melinda Gates Foundation to advance the development of dissolvable microneedle patches for polio immunization. The patches will be studied to evaluate their potential role as part of the worldwide efforts to eradicate polio.

The funds will support research and development of vaccine-filled microneedles that are designed to dissolve in the skin to provide protection against the poliovirus in humans. Studies with animal models have shown that microneedle patches containing polio vaccine effectively stimulate the immunological responses necessary for immunization.

A Phase I clinical trial funded by the award will evaluate whether the microneedle patches can be safely and effectively used to supplement current immunization efforts, bridging a gap between existing polio vaccines taken orally and those injected with conventional hypodermic needles.

Real-Time EEG Monitoring May Allow Automatic Control Of Anesthesia

Emery Brown says anesthesia drugs have been used in the US for more than 160 years, but were largely misunderstood — until now.

In operating rooms around the world, machines attached to anesthetized patients blip and bleep, reporting second-by-second accounts of vital organs. Blood circulation and respiration are closely monitored, but the one organ that is drugged, the brain, has no readout. Anesthesiologists simply watch for signs of wakening, says Emery Brown, the Edward Hood Taplin Professor of Medical Engineering and Computational Neuroscience at MIT.

Brown, who won a 2007 National Institutes of Health Director’s Pioneer Award to study how anesthesia drugs work, hopes to change that. Stat.
