Osteoarthritis is a leading cause of disability in the United States. This article describes a prioritized research agenda about osteoarthritis management developed for the Patient-Centered Outcomes Research Institute. Evidence gaps were identified by reviewing existing literature and engaging diverse stakeholders to expand and refine gaps. Stakeholders ranked evidence gaps by importance from their perspectives.Prioritized evidence gaps included the need to determine or evaluate key patient-centered outcomes; optimal duration, intensity, and frequency of nonsurgical interventions; whether the comparative effectiveness of nonsurgical interventions varies by socioeconomic factors; when and how to transition from nonsurgical to surgical interventions; effective ways to engage patients in self-management and promote long-term behavior change; standardized screening tools that improve early diagnosis; biomechanical strategies that improve symptoms; mechanisms for promoting and delivering coordinated, longitudinal care; and comparative effectiveness of nonsurgical therapies. Searches of PubMed and ClinicalTrials.gov showed many recent and ongoing studies addressing comparative effectiveness of nonsurgical interventions; relatively few of these evaluated treatments across categories (for example, drug therapy vs. weight management) or combined categories of treatment. Few studies addressed other high-priority evidence gaps.

On the night of 21 August 2013, sarin was dispersed in the eastern outskirts of Damascus, killing 1400 civilians and severely affecting thousands more. This article aims to delineate the clinical presentation and management of a mass casualty event caused by a nerve agent as shown in the social media. Authors searched YouTube for videos uploaded of this attack and identified 210 videos. Of these, 67 met inclusion criteria and were evaluated in the final analysis.These videos displayed 130 casualties; 119 (91.5%) of which were defined as moderately injured or worse. The most common clinical signs were dyspnea (53.0%), diaphoresis (48.5%), and loss of consciousness (40.7%). Important findings included a severe shortage of supporting measures and lack of antidotal autoinjectors. Decontamination, documented in 25% of the videos, was done in an inefficient manner. Protective gear was not noticed, except for sporadic use of latex gloves and surgical masks.This is believed to be the first time that social media was used to evaluate clinical data and management protocols to better prepare against future possible events.

Trials comparing implantable cardioverter-defibrillator (ICD) therapy with cardiac resynchronization therapy with a defibrillator (CRT-D) are limited to selected patients treated at centers with extensive experience.

The findings of the Women's Health Initiative (WHI) estrogen plus progestin (E+P) trial led to a substantial reduction in use of combined hormone therapy (cHT) among postmenopausal women in the United States. The economic effect of this shift has not been evaluated relative to the trial's $260 million cost (2012 U.S. dollars).

The Massachusetts 2006 health care reform has been called a model for the Affordable Care Act. The law attained near-universal insurance coverage and increased access to care. Its effect on population health is less clear.
