Newly discovered antibody may be body's natural defense against Alzheimer's

Researchers identified naturally occurring antibodies in human blood that selectively target toxic beta amyloid oligomers, potentially offering a natural defense mechanism against Alzheimer's. The antibodies recognize misfolded shapes of proteins, which could have implications for immune therapy of other neurodegenerative diseases.

Quality measurement, improvement of surgical care examined in the June issue of JACS

The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) reduces postoperative complications through comparative risk-adjusted adverse event data and prediction models. Studies show significant reductions in wound, surgical site infections, and urinary tract infections using ACS NSQIP.

First study of gun shows finds California laws reduce illegal gun purchases

A groundbreaking study published in Injury Prevention found that California's tight gun show regulations significantly reduced undocumented gun sales and 'straw' purchases outside of the state. The research, led by UC Davis director Garen Wintemute, observed increased regulation without affecting attendance or business at gun shows.

Studies link insurance coverage to more advanced cancers

Two new studies find that the uninsured and people with certain types of public health insurance are more likely to be diagnosed with more advanced cancer compared to those with private insurance. The strongest predictors of advanced disease were health insurance status and type, according to the studies published in CANCER journal.

Many doctors don't use patients' names on first visit

A study by Northwestern University's Feinberg School of Medicine found that 78% of survey respondents wanted to be greeted by a doctor's name, while only half addressed the patient by name in first-time visits. The researchers recommend using patients' first and last names for a respectful and comfortable introduction.

Tumor vessels identified by unique molecular markers

Researchers have identified a set of molecular markers that can distinguish between healthy and tumor blood vessels, paving the way for more selective anticancer therapeutics. The study reveals 13 genes selectively overexpressed in tumor blood vessels, offering new targets for developing safer therapies.

Bird song study gives clues to human stuttering

A recent study published in PNAS U.S.A. utilized functional MRI to examine the brain activity of awake, mildly sedated zebra finches during song stimulation. The research found that the right side of the birds' brains discriminated sounds better, suggesting a possible link between bird song and human speech disorders like stuttering.

Call of the child

Researchers found that mothers' brains respond more quickly and robustly to ultrasonic calls of mouse pups, enabling them to detect and discriminate between sounds. This improvement in brain function is associated with the ability to recognize behaviorally significant sounds, such as those made by their young.

Split the difference: Pill-splitting study looks at cost-saving step that could be used by millions

A new University of Michigan study shows that pill-splitting, slicing high-dose pills in half, can save Americans thousands of dollars on prescription drugs. Most participants said they would continue splitting pills if given a 50%-co-pay reduction, but some reported no issues with the practice.

Cancer stem cells can go it alone

A breast cancer cell line has been found to behave like cancer stem cells, allowing researchers to study the dynamics of cancer stem cells in tissue. This breakthrough could lead to targeted treatments for breast cancer by specifically targeting cancer stem cells for destruction while leaving normal stem cells intact.

Military service doubles suicide risk

A study of 320,000 men found that former military personnel are twice as likely to kill themselves as the general population, especially those with health problems. The research highlights the need for clinical and community interventions targeting veterans at risk.
