Environmental drivers of the spatiotemporal dynamics of respiratory syncytial virus in the United States.
The authors examined the association between environmental variables and state-specific measures of respiratory syncytial virus (RSV) seasonality. They found that states with low mean vapor pressure and the largest seasonal variation in potential evapotranspiration tended to experience biennial patterns of RSV activity, with alternating years of "early-big" and "late-small" epidemics. Their results successfully connected environmental drivers to the epidemic dynamics of RSV; however, the results do not fully explain why RSV activity begins in Florida, one of the warmest states, when RSV is a winter-seasonal pathogen.

Lower respiratory tract infection hospitalizations among American Indian/Alaska Native children and the general United States child population.
The authors described the change in lower respiratory tract infection-associated hospitalization rates for American Indian and Alaskan Native (AI/AN) children and for the general US child population aged less than 5 years. They found that the 2009-2011 AI/AN child average annual LRTI-associated hospitalization rate was 1.5 times higher than the US child rate. The Alaska and Southwest regions had the highest rates. The disparity was greatest for infant pneumonia-associated and 2009-2010 H1N1 influenza-associated hospitalizations.

The prevalence of bacterial infection in acute rhinosinusitis: a systematic review and meta-analysis.
The primary objective of this systematic review of 29 studies was to assess the prevalence of bacterial infection in adults with clinically diagnosed acute rhinosinusitis (ARS) who undergo culture from antral puncture or endoscopically directed middle meatus culture. The review provides evidence that the prevalence of bacterial infection in patients with clinically diagnosed ARS remains poorly defined, but is likely greater than the 0.5% to 2% figure previously widely quoted.
