To evaluate the clinical and microbiological outcomes of linezolid versus vancomycin in methicillin-resistant Staphylococcus aureus (MRSA) complicated skin and soft-tissue infection (cSSTI) using a meta-analysis. ⋯ Resolution of infection in CE and MITT patients were inconsistent; however, a sub-analysis revealed that linezolid was more likely to consistently achieve microbiologic eradication in MRSA ME patients. Apparent risks of thrombocytopenia, nausea, diarrhea, and possibly anemia may limit linezolid use in treating MRSA cSSTI. This study was limited due to an inability to assess for the effects of hetero-resistance and appropriate vancomycin dosing on outcomes. Moreover, the small number of studies made controlling for heterogeneity challenging.

As exacerbations of chronic obstructive pulmonary disease (COPD) significantly worsen patients' health status and increase disease-related mortality, greater control of exacerbations has important implications for improving patients' health and survival. The incremental benefits of pharmacologic therapies in preventing COPD exacerbations remain unclear. The objective of this observational study was to examine the risk of COPD-related exacerbations between groups of patients receiving inhaled corticosteroids (ICS), anticholinergics (AC), long-acting beta(2)-agonists (LABA), or fixed-dose combinations of ICS and LABA. ⋯ The present study found that use of bronchodilators, with or without ICS, in COPD patients resulted in a lower exacerbation rate when compared with ICS monotherapy. Further research is required to understand the clinical effects of specific pharmacologic therapies on COPD exacerbations, as well as their impact on long-term outcomes and costs.

To assess the impact of immune thrombocytopenic purpura (ITP) on primary care and specialist visits and workplace productivity. ⋯ ITP was consistently associated with more physician visits and worse work and productivity outcomes. Future research should build on these findings by calculating a comprehensive cost-of-illness of ITP including both direct and indirect costs.
