Review Meta Analysis
Rapid Tests for Influenza, Respiratory Syncytial Virus, and Other Respiratory Viruses: A Systematic Review and Meta-analysis.
Rapid diagnosis of respiratory virus infections contributes to patient care. This systematic review evaluates the diagnostic accuracy of rapid tests for the detection of respiratory viruses. We searched Medline and EMBASE for studies evaluating these tests against polymerase chain reaction as the reference standard. ⋯ Because of incomplete reporting, the risk of bias was often unclear. Despite their intended use at the point of care, 26.3% of tests were evaluated in a laboratory setting. Although newly developed tests seem more sensitive, high-quality evaluations of these tests are lacking.

Macrolide efflux encoded by mef(E)/mel and ribosomal methylation encoded by erm(B) confer most macrolide resistance in Streptococcus pneumoniae. Introduction of the heptavalent pneumococcal conjugate vaccine (PCV7) in 2000 reduced macrolide-resistant invasive pneumococcal disease (MR-IPD) due to PCV7 serotypes (6B, 9V, 14, 19F, and 23F). ⋯ The selective pressures of widespread macrolide use and PCV7 and PCV13 introductions on S. pneumoniae were associated with changes in macrolide resistance and the molecular basis over time in our population. Durable surveillance and programs that emphasize the judicious use of antibiotics need to continue to be a focus of public health strategies directed at S. pneumoniae.

Candida auris is an emerging, often multidrug-resistant pathogen with important public health implications. Infections are associated with high mortality, and prevention of transmission requires stringent infection control measures, making C. auris a potential barrier to transplantation. We describe the first donor-derived C. auris transmission in a lung transplant recipient.

Although new human papillomavirus (HPV) infections can occur at all ages, the age at which women acquire their "causal" HPV infection that develops into cervical cancer is poorly understood and practically unobservable. We aimed to estimate the age distribution at which individuals acquired their causal HPV infection in the absence of HPV vaccination or screening to help guide the optimal use of both. ⋯ Although new HPV infections and precancers can occur throughout a woman's lifetime, only a small proportion are acquired in mid-adult women and are vaccine-preventable. Our simulations highlight the potential limitations of using surrogate endpoints for vaccine efficacy studies of mid-adult women to guide policy decisions for implementation.
