The predictive value of small versus diminutive adenomas for subsequent advanced neoplasia.

Background And Aims: Patients with previous colorectal adenomas are at increased risk of colorectal cancer. Current guidelines for postpolypectomy surveillance intervals treat all tubular adenomas 1 to 9 mm in size with low-grade dysplasia as carrying the same level of risk. We evaluated whether 6 to 9 mm adenomas detected at colonoscopy are associated with greater risk of advanced neoplasia at follow-up compared with baseline 1 to 5 mm adenomas.

Sarcopenia and Physical Function in Middle-Aged and Older Stroke Survivors.

Objectives: To determine the prevalence of sarcopenia in stroke survivors using different methodologies, and compare a subset of the stroke group to age-, sex-, and body mass index (BMI)-matched nonstroke control counterparts.

Design: Cohort study.

Setting: A Veterans Affairs medical center and a university hospital.
