Background-Trial data for the benefits and risks of dabigatran versus warfarin in the treatment of nonvalvular atrial fibrillation are lacking. We sought to review real-world observational evidence for the comparative effectiveness and safety of these agents. Methods and Results-A systematic search of multiple databases was conducted from first available date to March 10, 2015 for longitudinal, observational studies comparing dabigatran with warfarin. Two reviewers evaluated studies for eligibility and extracted hazard ratios for ischemic stroke and gastrointestinal and intracranial bleeding. hazard ratios were pooled using random-effects meta-analysis. Metaregression was performed to assess treatment-effect heterogeneity. We identified 232 unique citations. Seven retrospective cohort studies met study eligibility criteria, with 348 750 patients and a mean follow-up of 2.2 years. In pooled analyses, dabigatran-150 mg was not superior to warfarin in preventing stroke (hazard ratio, 0.92; 95% confidence interval, 0.

Ultrasound models, commonly referred to as “phantoms,” are simulation tools for ultrasound education. Commercially produced phantoms are available, but there are “homemade” alternatives such as raw poultry and gelatin molds. Precooked, processed meat, better known as SPAM (Hormel Foods Corporation, Austin, MN), can be used as an ultrasound phantom to teach several ultrasound applications. It is a versatile, hygienic, and easily manipulated medium that does not require refrigeration or preparatory work and can be easily discarded at the end of use.

Background Although psychotherapy is one of the most efficacious and effective treatments for depression, limited accessibility to trained providers markedly limits access to care. In an attempt to overcome this obstacle, several platforms seeking to provide these services using digital modalities (eg, video, text, and chat) have been developed. However, the use of these modalities individually poses barriers to intervention access and acceptability. Multimodal platforms, comprising those that allow users to select from a number of available modalities, may be able to provide a solution to these concerns. Objective We aimed to investigate the preliminary effectiveness of providing psychotherapy through a multimodal digital psychotherapy platform. In addition, we aimed to examine differential responses to intervention by gender, self-reported physical health status, and self-reported financial status, as well as how prior exposure to traditional face-to-face psychotherapy affected the effectiveness of a multimodal digital psychotherapy intervention. Finally, we aimed to examine the dose-response effect. Methods Data were collected from a total of 318 active users of BetterHelp, a multimodal digital psychotherapy platform. Data on physical health status, financial status, and prior exposure to psychotherapy were obtained using self-report measures. Effectiveness was determined by the extent of symptom severity change, which was measured using the Patient Health Questionnaire at Time 1 (time of enrollment) and Time 2 (3 months after enrollment). Intervention dosage was measured as the sum of individual therapist-user interactions across modalities. Results Depression symptom severity was significantly reduced after the use of the multimodal digital psychotherapy intervention ( P <.001). Individuals without prior traditional psychotherapy experience revealed increased improvement after intervention ( P =.006). We found no significant dose-response effect of therapy, nor significant differences in outcomes across gender, self-reported financial status, and self-reported physical health status. Conclusions Users of BetterHelp experienced significantly reduced depression symptom severity after engaging with the platform. Study findings suggest that this intervention is equally effective across gender, self-reported financial status, and self-reported physical health status and particularly effective for individuals without a history of psychotherapy. Overall, study results suggest that multimodal digital psychotherapy is a potentially effective treatment for adult depression; nevertheless, experimental trials are needed. We discuss directions for future research.

Acute vertebral osteomyelitis is rare in the pediatric population. Its presentation may be subtle and without constitutional manifestations. We present a case of osteomyelitis of the odontoid process. The disease was not considered in the initial evaluation of an afebrile, nontoxic child who presented for evaluation of neck stiffness. Although there was a delay in diagnosis and treatment, the outcome was favorable.

Background: The Public Access Defibrillation (PAD) Trial was a randomized, controlled trial designed to measure survival to hospital discharge following out-of-hospital cardiac arrest (OOH-CA) in community facilities trained and equipped to provide PAD, compared with community facilities trained to provide cardiopulmonary resuscitation (CPR) without any capacity for defibrillation. Objectives: To report the implementation of community-based lay responder emergency response programs in 1,260 participating facilities recruited for the PAD Trial in the United States and Canada. Methods: This was a descriptive study of the characteristics of participating facilities, volunteers, and automated external defibrillator (AED) placements compiled by the PAD Trial, and a qualitative study of factors that facilitated or impeded implementation of emergency lay responder programs using focus groups of PAD Trial site coordinators. Results: The PAD Trial enrolled 1,260 community facilities (14.8% residential), with 20,400 lay volunteers (mean 6 standard deviation = 13.4 6 10.7 per facility)
