“Standardized patients” are trained actors who role-play the sort of diagnostic puzzles regularly faced by practicing physicians. They interact with students at the Tosteson Medical Education Center at Harvard Medical School (HMS).

A study by researchers at the Harvard T.H. Chan School of Public Health shows that moderate alcohol consumption can produce a temporary increase in heart attack and stroke risk.

An analysis of data from two long-term epidemiologic studies has found that regular use of aspirin significantly reduces the overall risk of cancer, an effect that primarily reflects a lower risk of colorectal cancer and other tumors of the gastrointestinal tract.

A new study out of Harvard Medical School and the National Running Center at Harvard-affiliated Spaulding Rehabilitation Hospital examined why runners get injured so often.

Children with acute lymphoblastic leukemia who live in high-poverty areas are substantially more likely to suffer early relapse than other patients, according to a new study.

The Gazette spoke with Michael Charness, chief of staff for the Harvard-affiliated VA Boston Healthcare System, about the CDC’s recommendations to sexually active woman of childbearing age: either use birth control or don’t drink.

A study of plaque production at single-cell level holds promise to help improve Alzheimer’s treatment.

Rett syndrome is a relatively common neurodevelopmental disorder, the second most common cause of intellectual disability in girls after Down syndrome. Building on 2004 findings, Harvard researchers identified a faulty signaling pathway that, when corrected in mice, improves the symptoms of Rett syndrome.

Researchers have found that cancer begins after activation of an oncogene or loss of a tumor suppressor, and involves a change that takes a single cell back to a stem cell state. They believe this model may apply not only to melanoma, but to most if not all cancers.

Researchers at MIT’s David H. Koch Institute for Integrative Cancer Research, in collaboration with scientists at the Harvard Stem Cell Institute and several other institutions, have developed an implantable device that in mice shielded insulin-producing beta cells from immune system attack for six months — a substantial proportion of life span.
