We evaluated the impact of guideline-concordant empiric antibiotic therapy on time to clinical stability, time to switch therapy, length of hospital stay, and mortality among patients with community-acquired pneumonia. ⋯ Among hospitalized community-acquired patients, guideline-concordant antibiotic therapy is associated with improved in-hospital survival and shorter time to clinical stability, time to switch therapy, and length of hospital stay.

Growing evidence suggests that oxidative damage caused by the beta-amyloid peptide in the pathogenesis of Alzheimer's disease may be hydrogen peroxide mediated. Many polyphenols, the most abundant dietary antioxidants, possess stronger neuroprotection against hydrogen peroxide than antioxidant vitamins. ⋯ Fruit and vegetable juices may play an important role in delaying the onset of Alzheimer's disease, particularly among those who are at high risk for the disease. These results may lead to a new avenue of inquiry in the prevention of Alzheimer's disease.

Public interest in herbal medicines has generated an increasing number of trials evaluating their efficacy. Trials with poor methodologic quality have exaggerated estimates of treatment effect, and incomplete reporting of trials causes difficulties in assessing trial methodologic quality. The objective of this project was to examine the quality of reporting of randomized controlled intervention trials of herbal medicine. ⋯ Important methodologic components of randomized controlled trials of herbal medicines are incompletely reported including allocation concealment, method used to generate the allocation sequence, and whether an intention-to-treat analysis was used. Also, key information unique to these trials may be missing, such as percentage of active constituents and type or form of the herbal medicine preparation. We suggest trialists consult a recent extension of the Consolidated Standard of Reporting Trials statement specific to herbal medicine trials when designing and reporting randomized controlled intervention trials of herbal medicines.
