Compounds secreted by frog skin are potent blockers of HIV infection

The findings could lead to topical treatments for preventing HIV transmission, and they reinforce the value of preserving the Earth's biodiversity.

Training for health workers improves the quality of tuberculosis care and control without requiring extra staff

Tuberculosis is a growing problem in lower and middle income countries, including South Africa. The World Health Organization estimates that about two thirds of people with tuberculosis are never diagnosed and so cannot benefit from treatment, leaving the epidemic unchecked despite global treatment programmes.

Risk of acquiring HIV rises during pregnancy

The risk of acquiring HIV rises during pregnancy, according to a study of women in Uganda's Rakai District led by researchers at the Johns Hopkins Bloomberg School of Public Health. The increased risk for acquiring HIV remained even after researchers controlled for behavior and other factors that contribute to HIV risk.

Clinical trials of daily oral antiretroviral dosing as pre-exposure prophylaxis

Writing in the journal Science, an international team of researchers, clinicians and others explains that a promising, relatively new approach is for people not infected but at high risk to take drugs that might prevent them from contracting HIV. But debate over the particulars of the strategy has slowed progress.

No specific antiretroviral drug-related "Crix belly" syndrome

Contrary to the concerns of many HIV-infected patients, there appears to be no specific antiretroviral drug-related "syndrome" of changes in body fat distribution in men wherein leg and arm fat decrease as belly fat increases, reports a study in the October issue of Journal of Acquired Immune Deficiency Syndromes (JAIDS).

Chicken virus helps develop novel vaccines

Researchers at the University of South Australia are developing novel vaccines by using a chicken virus to either stimulate or suppress the body's immune system.

Prevalence of "risky" sex in Scotland has doubled in the space of six years

...while unfounded confidence in the HIV negative status of casual partners has also increased, reveals research in Sexually Transmitted Infections.

Emergence of "POZ Parties"

The emergence of "POZ Parties" - parties exclusively for HIV positive men to meet other HIV positive men for sex - signals the potential to spread HIV "superinfection,"suggests research in Sexually Transmitted Infections.

Drug-releasing intravaginal ring could help prevent women from contracting HIV infection

The silicone vaginal ring steadily releases aciclovir: a treatment for genital herpes. It is known that women with genital herpes are at increased risk of HIV infection because the genital blisters caused by the infection increase the transmissibility of sexually acquired HIV.

Longer hospital stays do not mean better care

Physicians at The Johns Hopkins Hospital (JHH) have disproved the notion that longer hospital stays mean better care. They have successfully cut back on wait times across one dozen hospital departments and, as a result, reduced to well below six the average number of days patients with congestive heart failure, a need for dialysis or surgery, and many other conditions must spend in the hospital.

Pneumonia doesn't appear to harm HIV-positive patients any more than those without HIV

In a two-year study that documented cases in 26 hospitals in 11 countries including the United States, Canada, South Africa, Chile and Spain, outcomes for 58 HIV-positive patients with CAP, or community-acquired pneumonia (pneumonia contracted outside of hospitals) were compared with outcomes for 174 HIV-negative patients suffering a similar severity of CAP.

Testing for drug resistance in HIV-infected patients at the time of diagnosis may increase patients' life expectancy

Resistance to antiretroviral therapy, even in patients who have never received treatment, is a growing concern. However, genotype resistance testing, which involves looking for the presence of resistance genes, is not a standard procedure at the time a patient is diagnosed with HIV, probably due to lack of data on its benefits and its relatively high cost compared with other routine blood tests.

New study into the health-related quality of life for human immunodeficiency virus (HIV) patients

Pharmacists in Wales have conducted a new study into the health-related quality of life for human immunodeficiency virus (HIV) patients. The surprising results were revealed at the British Pharmaceutical Conference in Manchester.

Scientists eventually may be able to determine the structure of proteins from their genomic sequences

Computers can predict the detailed structure of small proteins nearly as well as experimental methods, at least some of the time, according to new studies by Howard Hughes Medical Institute researchers.

Stopping UK BCG vaccination well justified

From autumn 2005, the long running routine programme to vaccinate school children against tuberculosis with BCG vaccine will stop. This decision brings the UK into line with much of the rest of the world and is well justified, writes Professor Paul Fine in the British Medical Journal (BMJ).
