The casesOusman, a 32-year-old man; his 8-year-old daughter, Nene; and his 65-year-old mother, Mariama, from Casamance, Senegal, speak only Wolof and arrived in Canada six months ago from a refugee camp. What, if any, screening for latent tuberculosis should be done for this family?Active pulmonary tuberculosis was recently diagnosed in Harjit, a 65-year-old man who immigrated to Canada from India at age 32. Diabetes was diagnosed when he was 40 years old, and chronic renal failure developed one year ago that required dialysis because of the diabetes. Should screening for latent tuberculosis have been done for this man, and if so when?

Background:We aimed to define rates and causes of death in custody and after release in people admitted to provincial custody in Ontario, and to compare these data with data for the general population. Methods:We linked data on adults admitted to provincial custody in Ontario in 2000 with data on deaths between 2000 and 2012. We examined rates and causes of death by age, sex, custodial status and period after release, and compared them with data for the general population, using indirect adjustment for age.Results: Between 2000 and 2012, 8.6% (95% confidence interval [CI] 8.3%-8.8%) of those incarcerated died in provincial custody or after release. The crude death rate was 7.1 (95% CI 6.9-7.3) per 1000 person-years. The standardized mortality ratio for those incarcerated in 2000 was 4.0 (95% CI 3.9-4.1) overall and 1.9 (95% CI 1.5-2.4) while in provincial custody. The most common causes of death were injury and poisoning (38.2% of all deaths), including overdose (13.6%) and suicide (8.2%), diseases of the circulatory system (15.8%) and neoplasms (14.5%). In the 2 weeks after release, the standardized mortality ratio was 5.7 overall and 56.0 for overdose. Life expectancy was 72.3 years for women and 73.4 for men who experienced incarceration in 2000. Interpretation:Mortality was high for people who experienced incarceration, and life expectancy was 4.2 years less for men and 10.6 years less for women compared with the general population. Efforts should be made to reduce the gap in mortality between people who experience incarceration and those who do not. Time in custody could serve as an opportunity to intervene to decrease risk.
