Background: Attentional bias to pain-related information has been implicated in pain chronicity. To date, research investigating attentional bias modification training (ABMT) procedures in people with chronic pain has found variable success, perhaps because training paradigms are typically repetitive and monotonous, which could negatively affect engagement and adherence. Increasing engagement through the gamification (ie, the use of game elements) of ABMT may provide the opportunity to overcome some of these barriers.

An increasing number of procedures over the past two decades for aortic stenosis (AS) reflects the combination of an aging population and less invasive transcatheter options. As a result, the hemodynamics of the aortic valve (AV) have gained renewed interest to understand its behavior and to optimize patient selection. We studied the hemodynamic relationship between pressure loss (ΔP) and transvalvular flow (Q) of the normal AV as well as the impact of a variable supravalvular stenosis.

Introduction: The GOAL trial, a cluster randomized controlled trial, investigated the effect of comprehensive geriatric assessment (CGA) on frail older people with chronic kidney disease (CKD). This paper describes the following: (i) participant baseline characteristics, and (ii) their relationship with CKD stage and frailty severity.

Methods: Sixteen kidney outpatient clinics (clusters) were randomly allocated 1:1 to CGA or usual care.

Background And Objectives: One-third of prescriptions prescribed by a pediatric emergency department (PED) are not filled by patients. Fill rates improve with an onsite outpatient pharmacy (OOP). We aimed to increase the percent of PED discharge prescriptions sent to the OOP during open hours from 8.

Background: Despite advances in our understanding of the molecular underpinnings of meningioma progression and innovations in systemic and local treatments, recurrent meningiomas remain a substantial therapeutic challenge. The objective of this systematic review and meta-analysis is to provide a historical baseline, contemporary analysis, and propose a "rate of probable interest" to inform future clinical trial design and development on behalf of the RANO meningioma group.

Methods: PubMed, ClinicalTrials.
