Drug injectors with cutaneous anergy who are seropositive for HIV are at high risk of active tuberculosis, similar to that among untreated HIV-seropositive tuberculin reactors. A decreased incidence of active tuberculosis was seen in HIV-seropositive tuberculin reactors receiving 12 months of isoniazid chemoprophylaxis, compared with untreated or partially treated subjects. These results support the routine use of delayed-type hypersensitivity testing to accompany tuberculin testing for drug injectors with known or suspected HIV infection, and consideration of isoniazid prophylaxis for anergic as well as tuberculin-reactive subjects who are HIV seropositive, in populations with a high prevalence of coexisting HIV and Mycobacterium tuberculosis infection.
Objectives. We determined colorectal cancer (CRC) screening rates, predictors, and barriers in 2 major New York City shelter-based clinics. Methods. We extracted screening rates, sociodemographic characteristics, and factors associated with homelessness from medical records of domiciled and homeless patients aged 50 years and older (n = 443) with at least 3 clinic visits between 2010 and 2012. Results. The majority of patients were African American or Hispanic, 76% were male, and 60.7% were homeless (mean = 2.4 years; SD = 2.8 years). Domiciled patients were more likely than homeless patients to be screened (41.3% vs 19.7%; P < .001). Homeless and domiciled patients received equal provider counseling, but more homeless patients declined screening (P < .001). In logistic regression, gender, race, duration of homelessness, insurance status, substance and alcohol abuse, chronic diseases, and mental health were not associated with screening, but housing, provider counseling, and older age were. Conclusions. Proposed interventions to improve CRC screening include respite shelter rooms for colonoscopy prepping, patient navigators to help navigate the health system and accompany patients to and from the procedure, counseling at all clinical encounters, and tailored patient education to address misconceptions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
