Mandatory reporting of HIV infection to public health authorities, although now common, may deter people from undergoing testing. We examined HIV testing frequency in Alberta before and after mandatory reporting was implemented. We also examined the effect on testing rates among pregnant women when Alberta adopted an opt-out approach to prenatal HIV screening. ⋯ The introduction of mandatory reporting of HIV infection did not appear to have a deterrent effect on rates of HIV testing. The implementation of an opt-out prenatal HIV testing policy resulted in a dramatic increase in the number of females being tested for HIV infection.

Whether there is an association between depression at the time of acute myocardial infarction and subsequent risk of cardiac complications and death remains controversial. Most studies of this risk factor have been limited to patients of single institutions, and this might account for the varying results. We prospectively evaluated patients admitted to 5 tertiary care and 5 community hospitals and followed them for 1 year to measure the prevalence and prognostic impact of depressive symptoms after acute myocardial infarction. ⋯ Depressive symptoms are common after acute myocardial infarction and are associated with a slight increase in risk of in-hospital catheterization and angiography and readmission because of cardiac complications. Death was infrequent, with no statistically significant difference between the 2 groups.
