(Boston) –Boston Medical Center (BMC) and Boston University School of Medicine (BUSM) physicians have helped create the first set of clinical guidelines for treating patients with pulmonary hypertension in sickle cell disease. Elizabeth Klings, MD, director of the pulmonary hypertension inpatient and education program at BMC and associate professor of medicine at BUSM, spearheaded the development of these guidelines, which are published in the American Journal of Respiratory and Critical Care Medicine.

PITTSBURGH—So many variables can contribute to shortness of breath that no person can keep them all straight. But a computer program, capable of tracking more than 100 clinical variables for almost 400 people, has shown it can identify various subtypes of asthma, which perhaps could lead to targeted, more effective treatments.
Researchers from North Carolina State University have found a way to reduce the coercivity of nickel ferrite (NFO) thin films by as much as 80 percent by patterning the surface of the material, opening the door to more energy efficient high-frequency electronics, such as sensors, microwave devices and antennas.
We are less likely to humanize members of groups we don't belong to—except, under some circumstances, when it comes to members of the opposite political party. A study by researchers at New York University and Harvard Business School suggests that we are more prone to view members of the opposite political party as human if we view those individuals as threatening.
COLUMBIA, Mo. – Simulation-based engineering science (SBES) allows researchers to predict the effects of building explosions and analyze the response of building materials to those threats. Using a $400,000, five-year CAREER grant from the National Science Foundation, researchers at the University of Missouri developed the Material Point Method (MPM) a computer-generated tool that not only creates blast scenarios that informs blast and impact resistant materials and design, but also is crossing over into Hollywood animation—most recently, Disney's Oscar-winning animated film, Frozen.
BUFFALO, N.Y. – Social relationships, fatigue and other coexisting medical problems have a stronger effect on how patients with irritable bowel syndrome (IBS) rate their overall health than the severity of their gastrointestinal symptoms, a University at Buffalo study has found.
SAN DIEGO, Calif. (March 17, 2014)—Whenever fishing vessels harvest fish, other animals can be accidentally caught or entangled in fishing gear as bycatch. Numerous strategies exist to prevent bycatch, but data have been lacking on the global scale of this issue. A new in-depth analysis of global bycatch data provides fisheries and the conservation community with the best information yet to help mitigate the ecological damage of bycatch and helps identify where mitigation measures are most needed.
Bottom Line: Daily dietary supplements of omega-3 polyunsaturated fatty acids (also found in fish) or lutein and zeaxanthin (nutrients found in green leafy vegetables) were not associated with reduced risk for cardiovascular disease (CVD) in elderly patients with the eye disease age-related macular degeneration.
Author: The writing group for the Age-Related Eye Disease Study 2 (AREDS2) clinical trial.
Bottom Line: Neuroimaging for headaches is frequently ordered by physicians during outpatient visits, despite guidelines that recommend against such routine procedures.
Author: Brian C. Callaghan, M.D., M.S., of the University of Michigan Health System, Ann Arbor, and colleagues.
Background: Most headaches are due to benign causes, and multiple guidelines have recommended against routine neuroimaging for headaches.
In critically ill patients in Australia and New Zealand with severe sepsis or septic shock, there was a decrease in the risk of death from 2000 to 2012, findings that were accompanied by changes in the patterns of discharge of intensive care unit (ICU) patients to home, rehabilitation, and other hospitals, according to a study appearing in JAMA. The study is being released early to coincide with its presentation at the International Symposium on Intensive Care and Emergency Medicine.
Current evidence does not support nutritional guidelines that advocate high consumption of polyunsaturated fatty acids and low consumption of total saturated fats, according to an article being published in Annals of Internal Medicine.
PHILADELPHIA—A new study led by researchers at the Perelman School of Medicine at the University of Pennsylvania has found that the risk of hepatitis C-associated serious liver disease persists in HIV patients otherwise benefitting from antiretroviral therapy (ART) to treat HIV.
Improving the coordination of care for elderly patients with chronic diseases trims costs, reduces use of health services and cuts complications, according to a new RAND Corporation study.
Studying a large group of Medicare patients, researchers found that even modest improvements in the continuity of care among patients with diabetes, congestive heart failure or emphysema were associated with sizable reductions in use of hospital emergency departments and hospitalizations.
A new study indicates that in younger adults experiencing heart attacks and angina, men are more likely to receive faster care compared with women. The study, published in CMAJ (Canadian Medical Association Journal) also found that gender-related factors affected access to care for both men and women.
DALLAS, March 17, 2014 — Body odor is a deer hunter's worst enemy, an alert to animals that an ominous presence is lurking, but the science behind suppressing it to give hunters an edge oddly enough could help researchers develop a life-saving device for diabetes patients. Scientists today presented the latest advances that tie together these two seemingly unrelated fronts at the 247th National Meeting & Exposition of the American Chemical Society (ACS), the world's largest scientific society.
