Federally funded clinics for low-income patients as effective as private practices

A recent study found that Federally funded clinics for low-income patients demonstrated greater adherence to guidelines on six quality measures compared to private primary care practices. The clinics performed better in pharmacologic management of chronic diseases and appropriate use of screening tests, while performing similarly on ot...

Community health centers compare well with private practices, Stanford researcher finds

A new study published in the American Journal of Preventive Medicine found that community health center physicians performed as well as their private practice colleagues in 13 of 18 measures. Community health center physicians followed recommendations a higher percent of the time for certain conditions, such as congestive heart failure...

Dangerous caregivers for elderly

A study by Northwestern University found that many caregiver agencies do not conduct thorough background checks or provide adequate training for their employees. This can put vulnerable seniors at risk of abuse and neglect. The study suggests that consumers should be aware of the potential risks and take steps to ensure they hire a qua...

Researchers create 'MRI' of the sun's interior motions

Researchers have created an 'MRI' of the Sun's interior plasma motions, revealing that convective motions are approximately 100 times slower than previously projected. This challenges existing theories on heat transport and magnetic field generation, requiring a re-evaluation of sunspot formation and solar dynamics.

JCI early table of contents for July 9, 2012

Researchers have identified a protein called α9β1, which inhibits airway smooth muscle contraction and may be used to develop treatment options for asthma. Additionally, studies have shown that LRH-1 plays a crucial role in glucose-sensing and coordinating glucose and lipid metabolism in the liver.

Pediatric tumors traced to stem cells in developing brain​​

Scientists at Washington University School of Medicine found that stem cells from a specific part of the developing brain contribute to brain tumors caused by neurofibromatosis type 1. The study suggests that understanding the unique characteristics of these stem cells may lead to more effective treatments for pediatric brain tumors.

Training improves recognition of quickly presented objects

Researchers at Brown University found that training can improve recognition of rapidly presented objects by making the second target object a distinct color. This allows people to switch their attention more quickly and perceive the second target as effectively as a fifth of a second later.

PEPFAR HIV/AIDS programs linked to uptick in babies born at health facilities in sub-saharan Africa

A study by Columbia University's Mailman School of Public Health found that PEPFAR-funded HIV programs are associated with more deliveries at health facilities, suggesting a positive impact on maternal health services. This is likely due to the expansion of HIV treatment and infrastructure investments supporting other health services.

Researchers find new target deep within cancer cells

Researchers have found that blocking a fundamental process deep within cancer cells can selectively kill them and spare normal cells. This discovery reveals that accelerated reading of ribosomal genes is responsible for causing abnormal nucleoli and is necessary for the survival of cancer cells.

Taking nothing at face value

Research reveals that an image of a person can look strikingly different from one image to the next, making it difficult for unfamiliar viewers to identify them. However, familiar viewers find it easier to recognize individuals across various images. The study also found that variability within a person is greater than between people w...
