A cross-sectional population-based study of breast cancer screening among women with HIV in Ontario, Canada.

Background: As women with HIV live longer, the need for age-appropriate breast cancer screening will increase. We compared rates of screening mammography among women with and without HIV.

Methods: We used administrative health databases to identify all women in Ontario, Canada, who were eligible for screening mammography (aged 50 to 74 yr and no history of breast cancer) as of Apr.

Interval Colorectal Cancers following Guaiac Fecal Occult Blood Testing in the Ontario ColonCancerCheck Program.

Background. This work examines the occurrence of interval colorectal cancers (CRCs) in the Ontario ColonCancerCheck (CCC) program. We define interval CRC as CRC diagnosed within 2 years following normal guaiac fecal occult blood testing (gFOBT).

Appendectomy in mid and later life and risk of Parkinson's disease: A population-based study.

Introduction: Pathogenic movement of alpha-synuclein from the gut to the brain in PD has been proposed. The appendix has a relatively high density of alpha-synuclein deposition in neurologically healthy individuals. We investigated the incidence of PD after appendectomy.

Walk Score® and the prevalence of utilitarian walking and obesity among Ontario adults: A cross-sectional study.

Background: Evidence from large, population-based studies about the association between neighbourhood walkability and the prevalence of obesity is limited.

Data And Methods: The study population consisted of 106,337 people aged 20 or older living in urban and suburban Ontario, who participated in the National Population Health Survey and the Canadian Community Health Survey from 1996/1997 to 2008. Based on their postal code, individuals were grouped into one of five walkability categories, ranging from very car-dependent to "Walker's Paradise," according to the Street Smart Walk Score®, a composite measure of neighbourhood walkability.

Use of acute care hospital services by immigrant seniors in Ontario: A linkage study.

Background: Seniors constitute the largest group of hospital users. The increasing share of immigrants in Canada's senior population can affect the demand for hospital care.

Data And Methods: This study used the linked 2006 Census-Hospital Discharge Abstract Database to examine hospitalization during the 2004-to-2006 period, by immigrant status, of Ontario seniors living in the community.

Impact of renal insufficiency on short- and long-term outcomes after cardiac surgery.

Background: Renal insufficiency is highly prevalent in North America and has been established as a nontraditional risk factor for cardiovascular disease. Cardiovascular disease remains the primary cause of mortality in the general population and is often treated with coronary artery bypass surgery (CABG). This population-based study aimed to determine the risk of nondialysis dependent renal insufficiency (RI) on the long-term outcomes of patients who undergo CABG.
