Controlling TB in geographic hotspots could reduce citywide transmission

Reducing tuberculosis transmission in geographic "hotspots" where infections are highest could significantly reduce TB transmission on a broader scale, according to a study led by researchers at the Johns Hopkins Bloomberg School of Public Health. An analysis of data from Rio de Janeiro showed that a reduction in TB infections within three high-transmission hotspots could reduce citywide transmission by 9.8 percent over 5 years, and as much as 29 percent over 50 years. The study was published May 28 by the journal PNAS.

New insight into immune-cell movement patterns

By pairing an intimate knowledge of immune-system function with a deep understanding of statistical physics, a cross-disciplinary team at the University of Pennsylvania has arrived at a surprising finding: T cells use a movement strategy to track down parasites that is similar to strategies that predators such as monkeys, sharks and blue-fin tuna use to hunt their prey.

Longer looks: When is a life too long?; The rising cost of children's health care

I will tell you, what I feel most intensely when I sit by my mother's bed is a crushing sense of guilt for keeping her alive. Who can accept such suffering-;who can so conscientiously facilitate it? ... In 1990, there were slightly more than 3 million Americans over the age of 85. Now there are almost 6 million. By 2050 there will be 19 million-;approaching 5 percent of the population.

Ministers meet to discuss Global Plan to eliminate new HIV infections among children

UNAIDS and PEPFAR recently brought together the ministers of health and representatives of the 22 countries with the most new HIV cases among children to discuss progress on the Global Plan towards the Elimination of New HIV Infections among Children by 2015 and Keeping Their Mothers Alive, agreed to at the 2011 U.N. High-Level Meeting on AIDS, according to a UNAIDS press release.

Chronic diseases, bloodstream infections on the rise among HIV+ ICU patients

The expanded use of antiretrovirals, potent drugs used to treat retroviral infections such as human immunodeficiency virus (HIV), has been linked to significant decreases in hospital mortality rates among severely ill HIV-positive (HIV+) patients nationwide, primarily due to a decrease in opportunistic infections, according to a new study by researchers at Stanford University.

Severe hypersensitivity reactions to anti-HIV drug occur through autoimmune mechanism

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.

B cells in breast milk can produce HIV-neutralizing antibodies

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.
