A new clinical study led by UC San Francisco has identified a molecular test that can pinpoint breast cancer patients with the lowest risk of death, even 20 years after diagnosis. The test, called MammaPrint®, can accurately identify ultralow-risk tumors, which are associated with an excellent prognosis and minimal toxic effects.
Scientists at Georgetown University Medical Center found that alpha-Synuclein, a protein implicated in Parkinson's disease, is released when an infection occurs in the upper GI tract, inducing an immune response. Chronic infections may overwhelm the body's capacity to clear alpha-Synuclein, leading to disease.

This improvement in risk prediction enables a more informed choice of testing for patients with stable chest pain.
A recent study published in JAMA Pediatrics found that adolescents with ADHD have a 36% higher crash risk than other newly licensed teens, but this risk is still relatively low. The study suggests that evidence-based training and education for teens with ADHD who want to drive may help manage their risk.
Researchers found that leaders who change their moral minds are perceived as hypocritical and less effective, but framing the change as a result of a transformative experience can mitigate this perception. The study suggests that taking a moral stance without underlying beliefs can backfire if a leader needs to change their mind later.

The researchers discovered that reassurance from gastroenterologists, rather than diagnostic tests, drives patient satisfaction in this population.
The Trump administration's decision to remove sexual orientation and gender identity (SOGI) questions from national aging surveys and omit these categories from disability surveys may hinder the collection and use of SOGI data. This could set back years of progress in identifying and addressing LGBT health disparities.
Chronic fluid overload increases the risk of early death in kidney failure patients on hemodialysis, comparable to coronary artery disease and heart failure. The study found that cumulative exposure to fluid overload over 1 year predicted a higher risk of death than a single measurement at the start of dialysis treatment.
