Study reveals sarcoidosis-related mortality rates among black women

ATS 2012, SAN FRANCISCO – A new study conducted by researchers from Boston University has found that sarcoidosis accounts for 25 percent of all deaths among women in the Black Women's Health Study who have the disease. The study is the largest epidemiologic study to date to specifically address mortality in black females with sarcoidosis.

Results of the study will be presented at the ATS 2012 International Conference in San Francisco.

Internet politics, policies have rapidly become integral to US international affairs

Internet governance policy has rapidly risen from a relatively marginal issue for the United States' foreign policy establishment to a significant component of the country's international affairs and national security strategy, according to a new paper from Rice University's Baker Institute for Public Policy.

Sequence it…and they will come!

Rapid DNA sequencing may soon become a routine part of each individual's medical record, providing enormous information previously sequestered in the human genome's 3 billion nucleotide bases. This week's NEWSFOCUS section of the journal Science describes recent advances in sequencing technology.

Vitamin C improves lung function in newborns of pregnant smoking women

PORTLAND, Ore. — Women who are unable to quit smoking during pregnancy can significantly improve the lung function of their newborns by taking Vitamin C daily, according to a new study at Oregon Health & Science University Doernbecher Children's Hospital.

For monogamous sparrows, it doesn't pay to stray (but they do it anyway)

It's quite common for a female song sparrow to stray from her breeding partner and mate with the male next door, but a new study shows that sleeping around can be costly.

The 20-year study, which is reported in The American Naturalist, found that offspring conceived outside sparrows' social pairs go on to have lower reproductive success than within-pair offspring. The findings throw a monkey wrench into theories about why ostensibly monogamous animals might be inclined to cheat.

Newly discovered breast milk antibodies help neutralize HIV

DURHAM, N.C. – Antibodies that help to stop the HIV virus have been found in breast milk. Researchers at Duke University Medical Center isolated the antibodies from immune cells called B cells in the breast milk of infected mothers in Malawi, and showed that the B cells in breast milk can generate neutralizing antibodies that may inhibit the virus that causes AIDS.

Latest research examines colorectal cancer risk factors

San Diego, CA (May 22, 2012) — New research being presented at Digestive Disease Week® (DDW) looks at patient experiences with colorectal cancer screening and questions current screening guidelines. Worldwide, colorectal cancer is the second most common cancer in women and the third most common in men. Studies found that patients prefer colonscopy over computed tomography colonography, despite the former's more invasive nature, and highlight the importance of a patient's experience and role in the process of colonoscopy.

New TB test promises to be cheap and fast

Biomedical engineers at UC Davis have developed a microfluidic chip to test for latent tuberculosis. They hope the test will be cheaper, faster and more reliable than current testing for the disease.

"Our assay is cheaper, reusable, and gives results in real time," said Ying Liu, a research specialist working with Professor Alexander Revzin in the UC Davis Department of Biomedical Engineering.

The team has already conducted testing of blood samples from patients in China and the United States.

Excess maternal weight before and during pregnancy can result in larger babies

Excess weight in pregnant women, both before pregnancy and gained during pregnancy, is the main predictor of whether mothers will have larger than average babies, which can result in increased risk of cesarean section or trauma during delivery, states a study published in CMAJ (Canadian Medical Association Journal).

Bee pollen supplements can cause anaphylactic reactions

Although many people take bee pollen as a health supplement, it can cause severe anaphylactic reactions. However, most people are unaware of the risks, states an article published in CMAJ (Canadian Medical Association Journal).

Canada should significantly increase its funding of randomized clinical trials

Large randomized controlled trials (RCTs) are critical for determining effectiveness of medical therapies, tests and procedures. Yet Canada provides scant support for these studies compared with other western countries, states an analysis in CMAJ (Canadian Medical Association Journal).

5 percent of workers gave up smoking when the anti-tobacco law took effect

The enforcement of Law 42/2010, which extends the smoking ban to public places, has accompanied a progressive reduction in the percentage of smokers (from 40.3% to 35.3%) and in consumption amongst the working population. This decline applies to men and women of all ages and occupations.

EARTH: Carbon and the city

Alexandria, VA – In 2010, the world reached a milestone: The number of people living in urban areas reached 50 percent. This monumental shift from rural to urban living comes with consequences. Growing urban populations will have to learn to efficiently deal with increased demands for energy, transportation, sanitation, food and water while balancing the environmental impacts of such densely populated regions. Currently, 75 percent of global carbon dioxide emissions from fossil fuels come from cities, which cover just 3 percent of Earth's land surface.

Reactions to HIV drug have autoimmune cause, reports AIDS journal

Philadelphia, Pa. (May 22, 2012) – Potentially severe hypersensitivity reactions to the anti-HIV drug abacavir occur through an autoimmune mechanism, resulting from the creation of drug-induced immunogens that are attacked by the body's immune system, according to a study published online by the journal AIDS, official journal of the International AIDS Society.

Researchers take virus-tracking software worldwide

A biomedical informatics researcher who tracks dangerous viruses as they spread around the globe has restructured his innovative tracking software to promote even wider use of the program around the world.
