Missed colorectal cancers in a fecal immunochemical test-based screening program: Molecular profiling of interval carcinomas.

Background: For optimizing fecal immunochemical test (FIT)-based screening programs, reducing the rate of missed colorectal cancers (CRCs) by FIT (FIT-interval CRCs) is an important aspect. Knowledge of the molecular make-up of these missed lesions could facilitate more accurate detection of all (precursor) lesions.

Aim: To compare the molecular make-up of FIT-interval CRCs to lesions that are detected by FIT [screen-detected CRCs (SD-CRCs)].

Homeless and incarcerated: an epidemiological study from Canada.

Background: Incarceration and homelessness are closely related yet studied rarely. This article aimed to study the incarcerated homeless and identify specific vulnerabilities, which rendered them different from the nonincarcerated homeless. It also aimed to describe the homeless population and its significant involvement with the criminal justice and enforcement system.
