Previous studies have shown an inverse relationship between sexual activity and mortality in the general population. We evaluated the association between sexual activity and long-term survival among patients with acute myocardial infarction. ⋯ Using repeated assessments of sexual activity after myocardial infarction, an inverse association was demonstrated with mortality, which was only partly accounted for by measured potential confounders.

Very little evidence is available on the prevalence of serious spinal pathologies and the diagnostic accuracy of red flags in patients presenting to the emergency department (ED). This systematic review aims to investigate the prevalence of serious spinal pathologies and the diagnostic accuracy of red flags in patients presenting with low back pain to the ED. ⋯ We found a higher prevalence of serious spinal pathologies in the ED compared to the reported prevalence in primary care settings. As the diagnostic accuracy of most red flags was reported only by a single study, further validation in high-quality prospective studies is needed.
