The combination of vancomycin and piperacillin-tazobactam has been associated with an increased risk of acute kidney injury (AKI) in non-critically ill patient populations, but it is still unknown if this association exists in critically ill patients. The objective of this study was to compare the incidence of AKI development during therapy or within 72 hours after completion of therapy in adult critically ill patients who received vancomycin with concomitant piperacillin-tazobactam or cefepime. ⋯ After adjusting for propensity to receive each of the treatment choices, no significant difference was found in the incidence of AKI development or other outcomes between the groups. The previously described finding that concomitant vancomycin and piperacillin-tazobactam increases AKI in non-critically ill patients may not be generalizable to the critically ill population. Prospective evaluation of this hypothesis is warranted.

Chronic obstructive pulmonary disease (COPD) is a debilitating, irreversible disease with currently available therapies targeting symptom control and exacerbation reduction. A need for alternative disease-modifying therapies remains, specifically those that may have antiinflammatory and immunomodulatory properties that impact the pathophysiologic components of COPD. Statin drugs, the current gold standard for the treatment of dyslipidemia and prevention of cardiovascular disease (CVD), contain properties that affect the inflammatory disease processes seen in COPD. ⋯ Strong prospective evidence does not currently exist to suggest that statins provide a clinical benefit in patients with COPD who do not have other CVD risk factors. Benefits from statins that have been illustrated are likely explained by their impact on underlying CVD risk factors rather than the COPD disease process. An opportunity exists for unanswered questions to be addressed in future studies.

Observational Study
Effects of Medical Marijuana on Migraine Headache Frequency in an Adult Population.
No clinical trials are currently available that demonstrate the effects of marijuana on patients with migraine headache; however, the potential effects of cannabinoids on serotonin in the central nervous system indicate that marijuana may be a therapeutic alternative. Thus, the objective of this study was to describe the effects of medical marijuana on the monthly frequency of migraine headache. ⋯ The frequency of migraine headache was decreased with medical marijuana use. Prospective studies should be conducted to explore a cause-and-effect relationship and the use of different strains, formulations, and doses of marijuana to better understand the effects of medical marijuana on migraine headache treatment and prophylaxis.
