PURPOSE: To determine if reoperation rates are higher for patients who underwent isolated rotator cuff repair (RCR) than those who underwent RCR with concomitant biceps tenodesis using a large private-payer database. METHODS: A national insurance database was queried for patients who underwent arthroscopic RCR between the years 2007 and 2014 (PearlDiver, Warsaw, IN). The Current Procedural Terminology (CPT) 29,827 (arthroscopy, shoulder, surgical; with RCR) identified RCR patients who were subdivided into 3 groups-group 1: RCR without biceps tenodesis; group 2: RCR with concomitant arthroscopic biceps tenodesis (CPT 29827 and 29,828); group 3: RCR with concomitant open biceps tenodesis (CPT 29827 and 23,430)...

The growth, carcass and retail cut yield records on 1,428 Hanwoo steers obtained through progeny testing were analyzed in this study, and their heritability and genetic relationships among the traits were estimated using animal models. Two different models were compared in this study. Each model was fitted for different fixed class effects, date of slaughter for carcass traits and batch of progeny test live measurement traits, and a choice of covariates (carcass weight in Model 1 or backfat thickness in Model 2) for carcass traits...

Despite more than 25 years of a requirement for training in the responsible conduct of research (RCR), there is still little consensus about what such training should include, how it should be delivered, nor what constitutes "effectiveness" of such training. This lack of consensus on content, approaches and outcomes is evident in recent data showing high variability in the development and implementation of RCR instruction across universities and programs. If we accept that one of the primary aims of instruction in RCR/research ethics is "to foster a community of social responsibility" (Antes et al...

While it is well known that adenosine receptor activation protects the heart from ischemia/reperfusion injury, the precise mitochondrial mechanism responsible for the action remains unknown. This study probed the mitochondrial events associated with the cardioprotective effect of 5'-(N-ethylcarboxamido) adenosine (NECA), an adenosine A2 receptor agonist. Isolated rat hearts were subjected to 30min ischemia followed by 10min of reperfusion, whereas H9c2 cells experienced 20min ischemia and 10min reperfusion...

For the resection of pulmonary ground glass opacity (GGO) or non-palpable nodule on video-assisted thoracic surgery (VATS), preoperative computed tomography (CT)-guided VATS marker pricking is usually performed. Recently, air embolisms after VATS marker pricking have been reported to be serious problems. The purpose of this study was to evaluate the usefulness of intraoperative cone beam CT images on VATS to avoid preoperative VATS marker pricking. The CT number of the both GGO and nodule indicate the range from -200 to -800 HU in general...

BACKGROUND: Chronic pain is a common cause of reduced quality of life. Recent studies suggest that chronic pain patients have a different brain neurometabolic status to healthy people. Proton magnetic resonance spectroscopy ((1)H-MRS) can determine the concentrations of metabolites in a specific region of the brain without being invasive. PATIENTS AND METHODS: We recruited 56 chronic pain patients and 60 healthy controls to compare brain metabolic characteristics...

Simulation is a standard clinical nursing educational approach; however, simulation is rarely used in nonclinical nursing education. In doctor of philosophy (PhD) programs, ethical content about responsible conduct of research (RCR) is traditionally didactic, presented early in the program of study. Ethics content merits review before students begin the dissertation phase; thus, the purpose of this project was to design and implement simulated scenarios to help students apply RCR principles prior to beginning independent research...

Although recent evidence suggests ethics education can be effective, the nature of specific training programs, and their effectiveness, varies considerably. Building on a recent path modeling effort, the present study developed and validated a predictive modeling tool for responsible conduct of research (RCR) education. The predictive modeling tool allows users to enter ratings in relation to a given ethics training program and receive instantaneous evaluative information for course refinement. Validation work suggests the tool's predicted outcomes correlate strongly (r = 0...

Research misconduct negatively impacts the scientific community and society in general. Providing training in the responsible conduct of research (RCR) to researchers is one viable approach to minimizing research misconduct. Although recent evidence suggests ethics training can indeed be effective, little empirical work has examined the similarities and differences across fields. In the present study, we analyzed 62 empirical studies in engineering, biomedical science, social science, and mixed fields. The findings suggest certain instructional principles, or "golden rules," apply generally to all fields...

The incidence of arthroscopic rotator cuff repair (RCR) continues to rise. Given the changing healthcare climate, it is becoming increasingly important to critically evaluate current practice and attempt to make modifications that decrease costs without compromising patient outcomes. We conducted a study of the costs associated with arthroscopic anchorless (transosseous [TO]) RCR and those associated with the more commonly performed anchor-based TO-equivalent (TOE) method to determine whether there are any cost savings with the TO-RCR method...

Polyhydroxyalkanoate (PHA) mesh is a bioresorbable scaffold used to reinforce the suture-tendon interface in rotator cuff repairs (RCRs). We conducted a study of cyclic and ultimate failure properties of PHA mesh-augmented single-row RCRs and nonaugmented RCRs. Eight pairs of fresh-frozen cadaver humeri (6 male, 2 female) were tested. Mean (SD) age was 61 (9) years. The supraspinatus tendon was resected and reattached in a single-row configuration using 2 triple-loaded suture anchors and 6 simple stitches. The opposite humerus underwent RCR augmented with 2 strips of 13-mm × 23-mm PHA mesh...
