Study shows decreased risk of death from opportunistic infections with earlier antiretroviral treatment

HIV-positive people with opportunistic infections who receive earlier antiretroviral treatment lower their risk of death compared with people who delay treatment, according to a new study conducted by the Stanford University School of Medicine and published in PLoS One, the San Jose Mercury News reports.

Researchers develop questions to determine risk of HIV/AIDS drug resistance

Researchers from the Makerere University hospital in Uganda, the U.S. and Belgium have developed a formula, based on a set of questions, for determining HIV-positive people's risk of treatment failure and drug resistance, according to a study recently published in the Journal of the International AIDS Society, the New York Times reports.

Adult stem cells from bone marrow can deliver cancer-killing proteins to tumors

Researchers in London have demonstrated the ability of adult stem cells from bone marrow (mesenchymal stem cells, or MSCs) to deliver a cancer-killing protein to tumors.

Diabetics who have retinopathy should also be screened for obstructive sleep apnea

The eyes may be the window into the soul, but they may also contain important medical information. According to new research to be presented at the American Thoracic Society's 105th International Conference in San Diego on May 19, patients with diabetes who have retinopathy should also be screened for obstructive sleep apnea (OSA).

A new path for cocaine addiction research

Cocaine is one of the oldest drugs known to humans, and its abuse has become widespread since the end of the 19th century. At the same time, we know rather little about its effects on the human brain or the mechanisms that lead to cocaine addiction.

Doctors often miss whooping cough diagnosis in teens

Doctors can do a better job of diagnosing whooping cough among teens, an age group with a growing incidence of the illness, according to a University of Michigan study.

Smoking during pregnancy increases likelihood offspring will smoke

Children of mothers who smoked during pregnancy and their early childhood years may be predisposed to take up smoking as teens and young adults, compounding the physical damage they sustained from the smoke exposure.

Exposure to tobacco smoke early in life may lead to emphysema later on

The take-home message from our analysis is that exposure to tobacco smoke during childhood may be associated with detectable differences in lung structure, and perhaps early emphysema, later in life among people who do not themselves smoke.

Aerosol delivery of antibiotics via nanoparticles

Aerosol delivery of antibiotics via nanoparticles may provide a means to improve drug delivery and increase patient compliance, thus reducing the severity of individual illnesses, the spread of epidemics, and possibly even retarding antibiotic resistance.

Discovery of mutant genes in acute lymphoblastic leukemia

A research team has pinpointed a new class of gene mutations, which identify cases of childhood acute lymphoblastic leukemia (ALL) that have a high risk of relapse and death. The finding suggests specific drugs that could treat this high-risk leukemia subtype in children, particularly because such drugs are already in clinical trials for similar blood diseases in adults.

Genetic signature predicts clinical outcomes in certain types of breast cancer

Vanderbilt-Ingram Cancer Center researchers have uncovered a gene signature that may help predict clinical outcomes in certain types of breast cancer.

New vaginal ring designed to prevent sexual transmission of HIV

Researchers from Weill Cornell Medical College have published results showing that a new contraceptive device may also effectively block the transmission of the HIV virus. Findings show that the device prevents infection by the HIV virus in laboratory testing. The promising results are published in the most recent issue of the journal AIDS.

Protein neuregulin 1 critical to insulating the body's wiring could also become treatment target

A new protein identified as critical to insulating the wiring that connects the brain and body could one day be a treatment target for divergent diseases, from rare ones that lower the pain threshold to cancer, Medical College of Georgia researchers say.

Research may lead to improved TB vaccines

A team of Vanderbilt University Medical Center investigators has cracked one of clinical medicine's enduring mysteries - what happened to the tuberculosis vaccine. The once-effective vaccine no longer prevents the bacterial lung infection that kills more than 1.7 million people worldwide each year.

Molecular clues to halting HIV virus

Rice University's Andrew Barron and his group, working with labs in Italy, Germany and Greece, have identified specific molecules that could block the means by which the deadly virus spreads by taking away its ability to bind with other proteins.

Obese mothers, asthmatic kids

Babies born to obese mothers may have an increased risk of asthma, according to data from a new study to be presented on May 19 at the 105th International Conference of the American Thoracic Society in San Diego.

Enzyme-loaded liposomes within tiny polymer capsules

When cells cannot carry out the tasks required of them by our bodies, the result is disease. Nanobiotechnology researchers are looking for ways to allow synthetic systems take over simple cellular activities when they are absent from the cell. This requires transport systems that can encapsulate medications and other substances and release them in a controlled fashion at the right moment. The transporter must be able to interact with the surroundings in order to receive the signal to unload its cargo.

New flu compound

What happens if the next big influenza mutation proves resistant to the available anti-viral drugs? This question is presenting itself right now to scientists and health officials this week at the World Health Assembly in Geneva, Switzerland, as they continue to do battle with H1N1, the so-called swine flu, and prepare for the next iteration of the ever-changing flu virus.

Genetic variations may contribute to depression in heart disease patients

Individuals with heart disease are twice as likely to suffer from depression as the general population, an association the medical community has largely been unable to explain.
