A study found that 56% of HIV-infected gay men in the US are using combination therapy, but many are delaying treatment due to concerns about commitment and side effects. The study showed a strong link between advanced HIV infection and use of combination therapy.
Researchers at the University of Pittsburgh Medical Center have successfully transplanted lab-grown brain cells into a patient with paralysis and speech loss after a stroke, marking a significant breakthrough in stroke medicine. The study uses tissue grown in the lab to avoid ethical concerns surrounding fetal tissue use.
Anemia is a major cause of debilitating fatigue and early death in people with HIV. Research shows that treating anemia can reduce the risk of mortality, especially when related to antiretroviral therapy like AZT.
Researchers found that non-dermatologists prescribed less-effective yet more costly medications for fungal skin diseases. Dermatologists prescribed single agents with lower failure rates and costs. The study has implications for health maintenance organizations limiting access to specialists.
A rare medical archive enabled researchers to determine that patients with high nm23 levels and low density of newly formed blood vessels were more likely to survive 14 years after treatment. Low micro-vessel count was also a predictor, with 92% of patients surviving at least 14 years.
Seven mid-career health professionals from various institutions have been selected as Robert Wood Johnson Health Policy Fellows. They will work in congressional and executive branch offices to enrich their knowledge of public policy and foster a better understanding of government health activities.
Researchers create neural network pattern recognition software to predict battery performance and life, providing faster and cheaper data for manufacturers. The software uses only minutes of laboratory test data and can be used to build better batteries.
Researchers found that an enzyme called kinase IV is regulated by another enzyme called phosphatase 2A, which attaches to it and quickly shuts it down. This discovery provides insight into how cells control their activities and offers potential for developing targeted drugs to kill cancer cells or bacteria.
Squalamine, a novel liver steroid, has been shown to inhibit the growth of brain tumors called gliomas by disabling blood vessel formation. In laboratory tests, it proved as effective as carmustine in slowing tumor growth and constricting blood vessels, suggesting potential as a human therapy.
A 51-year-old man with a rare brain disorder, known as 'sagging brain,' was treated at UCSF after initial diagnoses failed to provide relief. Exhaustive neurological scrutiny led to the discovery of a ruptured cyst causing the condition, which was successfully treated through surgery.
A study of 1235 adults found that obesity was associated with reduced breathing capacity, but only when fat mass was present. Handgrip strength and muscular fitness were also linked to improved lung function, suggesting a mediating role in the relationship between body composition and respiratory function.
The National Science Board will hold a public hearing to investigate effective teaching and learning of mathematics and science in K-12 education. The hearing aims to identify key contributors to successful reform strategies and discuss evidence of actual impact on student achievement.
A NASA image reveals the significant impact of urbanization on Sacramento's city temperature, with buildings reaching up to 140 degrees F. The study emphasizes the importance of urban forests in regulating city temperatures and suggests that their extent and arrangement play a crucial role in mitigating heat island effects.
Two studies found a direct relationship between RN staff mix and lower rates of medication errors, patient falls, and other adverse occurrences. However, the optimal RN staffing level remains unclear, with medication errors increasing above 87.5% RN care hours.
The study found that dietary DHA and EPA supplementation significantly influenced heart rate, with improved left ventricular diastolic filling observed in the marine oil groups. The fatty acid composition of plasma phospholipids may affect cardiac mechanics in humans.
Researchers have made progress toward a gene therapy for HIV infection by genetically altering virus-fighting T-cells to recognize and attack HIV-infected cells. The study found that engineered T-cells persisted in the bloodstream for at least 100 days after infusion, proliferating and providing long-term immunity.
A new study by University of California San Francisco researchers has found that HIV patients who feel part of their community and involved in their own care are more likely to take their medication and follow medical advice. In contrast, those feeling detached or depressed are more likely to disregard treatment.
A recent study published in Annals of Internal Medicine found that testosterone administration significantly increases lean body mass and improves the quality of life in men with AIDS wasting syndrome. The treatment was shown to produce significant term benefits, making it an important new therapy for patients with this condition.
Physicians at UPMC are evaluating LBS-Neurons for treating stroke patients with a clinical human neuron transplant. The transplanted neurons aim to improve damaged host neurons or replace destroyed ones, showing promise in correcting cognitive and motor deficits.
Researchers investigated enteral supplements' impact on AIDS patients, finding net increases in protein and energy intakes. However, fat-free mass did not increase for the group as a whole, but was inversely correlated with baseline synthesis of fat.
Researchers at Northwestern University have identified a new regulatory molecule, HSBP-1, that regulates the production of heat shock proteins in response to stress. This finding may lead to new insights into cell death associated with aging and diseases such as heart disease and stroke.
A team of researchers documented a case of transmission of protease-resistant HIV, which is resistant to six of the 11 approved HIV anti-retroviral drugs. The patient was infected through unprotected anal intercourse with a partner who had previously been treated with these drugs, highlighting the need for continued prevention efforts.
Human factors researchers from Georgia Tech's Electronics Systems Laboratory are helping Kaman and Litton develop a new flight system for the Royal Australian Navy's SH-2 Seasprite helicopters. The team is focusing on creating an intuitive interface that enables two-person crews to fly the aircraft safely and efficiently.
