Subclavian and axillary artery injuries are uncommon. In addition to many open vascular repairs, endovascular techniques used for definitive repair or control of these anatomically challenging injuries. The aim this study was determine the relative roles in management subclavian comparing hospital outcomes, long-term limb viability.A multicenter, retrospective review patients with from January 1, 2004, December 31, 2014, completed at 11 participating Western Trauma Association institutions....

Abstract Background Research has focused on screening for adverse childhood experiences, rather than provision of education as a part routine anticipatory guidance. An experiences ‘conversation’ is one method that not been studied empirically but represents complimentary or alternative approach to which could overcome many existing barriers. Objectives This study aims examine parent/guardian and provider acceptability/feasibility the conversation during well-child visits in primary care....

Background: Addiction shift (also known as "Cross," "Transfer," or "Substitute" addiction) is a common theme that emerges in the literature on recovery from substance use disorders. Some research has suggested those who recover one disorder are at increased risk of developing another. Despite existing this area, little about how individuals may be an addiction to food they disorder.Methods: The current study sought examine shift, specifically substances 44 participants undergoing residential...

Nine breast cancer quality measures (QM) were selected by the American Society of Breast Surgeons (ASBrS) for Centers Medicare and Medicaid Services (CMS) Quality Payment Programs (QPP) other performance improvement programs. We report member performance.Surgeons entered QM data into an electronic registry. For each QM, aggregate "performance met" (PM) was reported (median, range percentiles) benchmarks (target goals) calculated CMS methodology, specifically, Achievable Benchmark Care™ (ABC)...

A possible multiplexer design for the focal plane Cassini Visible and Infrared Mapping Spectrometer (VIMS) is reviewed. The instrument's requirements multiplexed array are summarized. VIMS instrument has a modest radiation-hardness requirement due to trajectory planetary environments in which will be required operate. total ionizing dose hardness few tens of kilorads. thin-gate oxide hundred angstroms thickness used. Field achieved by guard bands or hardened dielectric isolation. argued meet...

Temporal attention, the allocation of attention to a moment in time, improves perception. Here, we examined computational mechanism by which temporal perception, under divisive normalization framework. Under this framework, can improve perception target signal three ways: stimulus enhancement (increasing gain across all sensory channels), (selectively increasing channels that encode stimulus), or external noise exclusion (reducing irrelevant features). These mechanisms make diverging...

Introduction: Half of grade school-age children in the U.S. receive after school care from their grandparents or another adult family member. Yet, few studies have investigated if educating youth about stroke is an effective vehicle for spreading knowledge to families and impact on onset-to-door time. Objective: To assess level warning signs behavioral actions school-aged children. Methods: Surveys differentiated each level- elementary (K-5), middle (6-8) high (9-12) - were administered...

Receptive fields in early visual cortex change systematically with eccentricity and area. Model-based functional neuroimaging approaches provide a method to map interrogate population receptive (pRF) spatial frequency tuning (pSFT), though how closely the response properties derived from these methods correspond one another remains unclear. Here, we compared pRF maps pSFT estimates (V1 – V3). Preferred bandwidth of voxel-wise were estimated log Gaussian function (see Aghajari, Vinke, & Ling,...
