INTRODUCTION: Shared use of recreational facilities is a promising strategy for increasing access to places for physical activity. Little is known about shared use in faith-based settings. This study examined shared use practices and barriers in faith communities in North Carolina. METHODS: Faith communities in North Carolina (n = 234) completed an online survey (October-December 2013) designed to provide information about the extent and nature of shared use of recreational facilities...

Multiple studies showed the prognostic capacities of tumor-infiltrating lymphocytes (TILs) in triple-negative breast cancer (TNBC), but not in other subtypes. We evaluated tumor expression of FAS, a key receptor in T-cell mediated apoptosis, as possible explanation for this differential prognostic value of TILs. Furthermore, we evaluated the prognostic relevance of FAS, both as an independent biomarker and in relation to CD8-positive T-cell presence. The study cohort consisted of 667 breast cancer patients treated in the LUMC between 1997 and 2009...

Strategies to value physician work continue to evolve. The Society of Thoracic Surgeons and The Society of Thoracic Surgeons National Database have an increasingly important role in this evolution. An understanding of the Current Procedural Terminology (CPT) system (American Medical Association [AMA], Chicago, IL) and the Relative Value Scale Update Committee (RUC) is necessary to comprehend how physician work is valued. In 1965, with the dawn of increasingly complex medical care, immense innovation, and the rollout of Medicare, the need for a common language describing medical services and procedures was recognized as being of critical importance...

BACKGROUND: Ogilvie's syndrome (OS) is a relatively uncommon pathology characterized by significant colonic dilation in the absence of mechanical obstruction. If unrecognized and untreated, cecal perforation resulting in mortality rate of 25-71% may occur. It is a potentially underdiagnosed condition in the lateral transpsoas appraoch population due to its uncommon nature and imitation of other well-known pathologies. METHODS: A total of 2930 patients from 6 separate institutions were retrospectively reviewed since 2007 and screened for OS...

BACKGROUND: Although premature beats are a matter of concern in horses, the interpretation of equine ECG recordings is complicated by a lack of standardized analysis criteria and a limited knowledge of the normal beat-to-beat variation of equine cardiac rhythm. The purpose of this study was to determine the appropriate threshold levels of maximum acceptable deviation of RR intervals in equine ECG analysis, and to evaluate a novel two-step timing algorithm by quantifying the frequency of arrhythmias in a cohort of healthy adult endurance horses...

BACKGROUND: Atazanavir is boosted with the cytochrome P450 (CYP) 3A4 inhibitor ritonavir. When combined with the CYP3A4 substrate daclatasvir, the daclatasvir dosage should be reduced from 60 to 30 mg once daily. Recently, cobicistat was licensed as a CYP3A booster and used with atazanavir. OBJECTIVES: To determine whether the fixed-dose combination of atazanavir/cobicistat has an influence on daclatasvir pharmacokinetics comparable to that of the separate agents atazanavir and ritonavir...

BACKGROUND: Recently, numerous models and techniques have been developed for analyzing and extracting features from the T wave which could be used as biomarkers for drug-induced abnormalities. The majority of these techniques and algorithms use features that determine readily apparent characteristics of the T wave, such as duration, area, amplitude, and slopes. METHODS: In the present work the T wave was down-sampled to a minimal rate, such that a good reconstruction was still possible...

The purpose of this study was to explore Rwandan nursing clinical instructors' (CIs) experiences of structural and psychological empowerment. CIs play a vital role in students' development by facilitating learning in health care practice environments. Quality nursing education hinges on the CI's ability to enact a professional role. A descriptive qualitative method was used to obtain an understanding of CIs empowerment experiences in practice settings. Kanter's Theory of Structural Power in Organizations and Spreitzer's Psychological Empowerment Theory were used as theoretical frameworks to interpret experiences...

BACKGROUND: Data routinely captured in clinical registries may be leveraged to enhance efficiency of prospective research. The quality of registry data for this purpose has not been studied, however. We evaluated the completeness and accuracy of perioperative data within congenital heart centers' local surgical registries. METHODS: Within 12 Pediatric Heart Network (PHN) sites, we evaluated 31 perioperative variables (and their subcategories, totaling 113 unique fields) collected via sites' local clinical registries for submission to The Society of Thoracic Surgeons Database, compared with chart review by PHN research coordinators...

PURPOSE: We investigated whether Brugada syndrome (BrS)-associated variants identified in the general population have an effect on J-point elevation as well as whether carriers of BrS variants were more prone to experience syncope and malignant ventricular arrhythmia and had increased mortality compared with noncarriers. METHODS: All BrS-associated variants were identified using the Human Gene Mutation Database (HGMD). Individuals were randomly selected from a general population study using whole-exome sequencing data (n = 870) and genotype array data (n = 6,161) and screened for BrS-associated variants...

BACKGROUND: Risk stratification in patients with type 3 long-QT syndrome (LQT3) by clinical and genetic characteristics and effectiveness of β-blocker therapy has not been studied previously in a large LQT3 population. METHODS: The study population included 406 LQT3 patients with 51 sodium channel mutations; 391 patients were known to be event free during the first year of life and were the focus of our study. Clinical, electrocardiographic, and genetic parameters were acquired for patients from 7 participating LQT3 registries...

BACKGROUND: Despite reports advocating for integration of research into healthcare delivery, scant literature exists describing how this can be accomplished. Examples highlighting application of qualitative research methods embedded into a healthcare system are particularly needed. This article describes the process and value of embedding qualitative research as the second phase of an explanatory, sequential, mixed methods study to improve antibiotic stewardship for acute sinusitis. METHODS: Purposive sampling of providers for in-depth interviews improved understanding of unwarranted antibiotic prescribing and elicited stakeholder recommendations for improvement...

OBJECTIVE: A retrospective review of the clinical and radiographic outcomes from a multi-center study of surgical treatment for high-grade spondylolisthesis (HGS) in adults. The objective was to assess the safety of surgical reduction, its ability to correct regional deformity, and its clinical effectiveness. METHODS: Retrospective, multi-center review of adults (age >18 y) with lumbo-sacral HGS (Meyerding grade 3-5) treated surgically with open decompression, attempted reduction, posterior instrumentation and interbody fusion...

New capabilities at X-ray free-electron laser facilities allow the generation of two-colour femtosecond X-ray pulses, opening the possibility of performing ultrafast studies of X-ray-induced phenomena. Particularly, the experimental realization of hetero-site-specific X-ray-pump/X-ray-probe spectroscopy is of special interest, in which an X-ray pump pulse is absorbed at one site within a molecule and an X-ray probe pulse follows the X-ray-induced dynamics at another site within the same molecule. Here we show experimental evidence of a hetero-site pump-probe signal...

BACKGROUND: There is increasing interest in reducing the duration of mechanical ventilation after pediatric cardiac operations. However, the contemporary use of an early extubation strategy and its effect on clinical outcomes is poorly understood. METHODS: Data from The Society of Thoracic Surgeons Congenital Heart Surgery Database (2010 to 2013) were analyzed to determine the association of early extubation with postoperative length of stay (PLOS). Two operations were analyzed: complete repair of tetralogy of Fallot (TOF) in patients older than 45 days and the Fontan procedure...
