Study highlights the ramifications of medical misdiagnosis

Inaccurate diagnoses led to painful biopsies that in themselves worsened the condition of patients with rare muscle-to-bone disease. more  

Study finds low birth weight rates vary widely across US

Low birth weight, an important risk factor of infant mortality and childhood developmental disorders, varies more than 3-fold in regions across the U.S., according to national research conducted at Dartmouth Medical School. The study offers promise for health care experts in an area of prenatal health where progress has been elusive. more

Adolescents who watch smoking in movies are more likely to try smoking

The first national study to look at the connection between smoking in movies and smoking initiation among adolescents shows that exposure to smoking in popular films is a primary risk factor in determining whether young people will start smoking. more  

A recipe for overeating: Studies outline dangers of mixing stress, deprivation and tempting foods

Two studies in the October issue of Behavioral Neuroscience show that when animals are stressed, deprived and exposed to tempting food, they overeat, with different degrees of interaction. The powerful interplay between internal and external factors helps explain why dieters rebound and even one cookie can trigger a binge if someone's predisposed to binge. more

Turning sensation into perception  

Perceiving a simple touch may depend as much on memory, attention, and expectation as on the stimulus itself, according to new research from Howard Hughes Medical Institute (HHMI) international research scholar Ranulfo Romo and his colleague Victor de Lafuente. The scientists found that monkeys' perceptions of touch match brain activity in the frontal lobe, an area that assimilates many types of neural information. more

Mutations in the BRAF gene predict sensitivity to a novel class of cancer drugs 

A team of researchers led by scientists at Memorial Sloan-Kettering Cancer Center have discovered that a new class of drugs -- now in early stage clinical trials -- work best in patients with mutations in the BRAF gene. BRAF is a protein that plays a central role in the growth and survival of cancer cells and is mutated in the majority of patients with melanoma and in a minority of patients with colon, breast, and lung cancers. The findings, available in an advance online publication of Nature, represent a potential targeted therapy tailored for patients whose tumors contain this mutation. more

Unrelated adults in the home associated with child-abuse deaths

Young children who live in households with one or more unrelated adults are nearly 50 times as likely to die from an inflicted injury, usually being shaken or struck, as children living with two biologic parents, report researchers from the University of Missouri-Columbia and the University of Chicago in the November 2005 issue of the journal Pediatrics. more
