An increase in the incidence of cancer among elderly people assigned to pravastatin therapy has been reported in a randomized controlled trial; however, this finding has been attributed to chance. Our aim was to assess the effect of pravastatin therapy on cancer risk and to examine whether the effect varies according to age by performing a detailed meta-analysis and meta-regression analysis of randomized controlled trials. ⋯ Our findings suggest an association between pravastatin therapy and cancer in elderly patients. However, given the importance of this potential association, further verification is warranted.

Public health advisories have warned that the use of atypical antipsychotic medications increases the risk of death among elderly patients. We assessed the short-term mortality in a population-based cohort of elderly people in British Columbia who were prescribed conventional and atypical antipsychotic medications. ⋯ Among elderly patients, the risk of death associated with conventional antipsychotic medications is comparable to and possibly greater than the risk of death associated with atypical antipsychotic medications. Until further evidence is available, physicians should consider all antipsychotic medications to be equally risky in elderly patients.

The rate of elective primary cesarean delivery continues to rise, owing in part to the widespread perception that the procedure is of little or no risk to healthy women. ⋯ Although the absolute difference is small, the risks of severe maternal morbidity associated with planned cesarean delivery are higher than those associated with planned vaginal delivery. These risks should be considered by women contemplating an elective cesarean delivery and by their physicians.
