A study found a significant increase in radiology tests in managed care settings, with an average cost per patient increasing by $214 over 10 years. Newer technologies like CT and MRI scans also saw a rise, but their use was not as efficient as expected.
Researchers have found a way to 'rescue' immune cells that are exhausted from fighting off HIV infection using the molecule Tim-3, which is present at high levels on poorly functional immune system cells. Blocking the activity of Tim-3 improved cell function and allowed them to rejoin the battle against HIV.
Pregnant women who wait out stalled labor for an extra two hours can reduce health risks and eliminate over 130,000 C-section deliveries per year. A new study by researchers at UCSF found that one-third of women achieve a normal delivery without harm.

The study also showed that smoke exposure impairs the body's natural repair mechanisms, leading to persistent effects on vascular health.
Researchers at UCSF have made a groundbreaking discovery on how neurons coordinate to generate movement. Individual neurons do not fire independently across the entire duration of a motor function as previously thought but instead coordinate their activity with other neurons. The study revealed that each neuron encodes different aspec...
A computer-based program using a video doctor sharply reduces HIV-positive patients' sexual and drug risk behaviors, according to UCSF researchers. The Positive Choice program was tested at five San Francisco Bay Area outpatient clinics and showed significant reductions in risky behaviors among participants.
The 2004 California Long-Term Care Reimbursement Act increased MediCal costs by nearly 9% but failed to improve quality or access to care. Nursing home staffing levels remained lower than recommended numbers, and staff turnover increased significantly.
Scientists identified Lis1 gene as essential for neuroepithelial stem cell division in mice, providing insight into brain development and potential link to lissencephaly. The study suggests neural migration defects may be caused by defects in other processes like proliferation and division.
Female zebra finches strongly preferred directed, courtship songs with less variability in pitch, indicating an ear for detail. The study's findings also suggest that females' preferences shape male song behavior over time, highlighting the importance of social communication in birdsong production and perception.
Researchers at UCSF have developed a new model for estimating breast cancer risk, incorporating breast density and ethnicity, which is well-calibrated and reasonably accurate across risk factor subgroups. The model may one day be used to calculate a woman's risk for breast cancer during mammograms.

The study found that these men are 13 times more likely to be infected than the general population, highlighting the need for increased awareness and prevention measures.
Researchers found that teens who remained sexually inexperienced reported fewer positive benefits from refraining from sex, while those who were sexually experienced valued refraining more. The study suggests that adults should guide teens on coping with both positive and negative outcomes of sexual behaviors.
A new brain mapping technique has refined scientists' understanding of language organization within the human cortex, identifying new regions involved in speech production, reading, and naming. The technique allows for safer tumor removal and better outcomes for patients with language-related difficulties.

This discovery has implications for rehabilitating patients following strokes and other damage to the nervous system.
A large-scale study found that patients cared for by hospitalists had shorter hospital stays and lower treatment costs, with modestly lower mortality rates compared to general internists and family physicians. The study's findings support the benefits of hospitalist care and highlight its potential to improve healthcare efficiency.
A new drug has been found safe and effective at reducing levels of 'bad' LDL cholesterol by up to 40 percent, a promising approach for treating high cholesterol and related conditions. The drug accelerates the natural process of ridding the body of LDL, offering an alternative to statins and potentially complementing their use.
Researchers found that newly HIV-infected men in the US dramatically shifted their behavior to choosing only unprotected sex with other infected individuals. This change reflects a systematic shift among men, mostly gay, to protect their partners from HIV infection.
A new study found that up to 37% of males and 44% of females will be obese when they turn 35 years old, leading to increased heart attacks, chronic chest pain, and deaths. The study projects over 100,000 extra cases of heart disease by 2035.
The Global Health Group, led by Sir Richard Feachem, will focus on malaria eradication and private sector strengthening in developing countries. The team aims to overcome current bottlenecks and test new approaches on a large scale.

A study led by UCSF researchers identified p16 and COX-2 biomarkers as predictors of future tumor formation in women with ductal carcinoma in situ (DCIS). The findings suggest that these biomarkers can help determine the best treatment option for DCIS patients.
Researchers have identified a potential new way of fighting against HIV infection by targeting human endogenous retroviruses (HERV). A vaccine containing HERV antigens could stimulate T-cells that target cells expressing HERV, potentially protecting people from becoming infected or limiting damage caused by HIV.
