BACKGROUND Residents are undertrained to perform acute pediatric sexual abuse evaluations. The American Academy of Pediatrics has proposed development of an adaptable child abuse curriculum, though no such curriculum exists. OBJECTIVES Our goal was to perform a needs assessment for pediatric residents performing acute sexual abuse evaluations in an emergency department setting, thus laying groundwork for an adaptable curriculum. The objective was to explore pediatric resident training, knowledge, confidence, expectations, learning needs, and educational goals. PARTICIPANTS AND SETTING We conducted a qualitative exploratory study of pediatric residents, faculty, and program directors at two academic health centers in New York City. METHODS Using purposive and convenience sampling, we conducted focus groups and semi-structured interviews until saturation of ideas was achieved. Through an iterative process using constructivist grounded theory, themes were organized into a curricular model. RESULTS We conducted 3 resident focus groups (n = 21) and 7 interviews with emergency medicine, pediatric, and child abuse faculty. Themes emerged in three categories barriers (e.g., knowledge deficits), facilitators (e.g., pre-learning), and educational goals. Despite recognizing the importance and increased availability of subspecialists, participants supported gradual autonomy for pediatric residents in the evaluation of suspected sexual abuse, with a goal of independent competency in history and examination skills, and supervised competency of forensic evidence collection. CONCLUSIONS Our data support a multimodal, blended curriculum for the acute sexual abuse evaluation, including (1) asynchronous pre-learning; (2) live workshops; (3) reference tools; and (4) modeled clinical experiences. Our proposed curricular model may be utilized by a variety of frontline clinicians. PURPOSE Hepatocellular carcinoma (HCC) is the seventh most commonly diagnosed cancer and the fourth-leading cause of cancer-related death worldwide. Chronic hepatitis B virus (HBV) is the leading cause of HCC in China. Emerging evidence suggests that long noncoding (lnc)-RNAs are deregulated and are involved in the development of HCC. Our previous study found that HBV X protein can promote HCC by altering lncRNA expression profiles. The purpose of this study was to investigate the expression of the lncRNA semaphorin 6A-antisense RNA 1 (SEMA6A-AS1) and its prognostic value in HBV-related HCC. METHODS Samples of HCC tissues and adjacent nontumor tissues were collected from patients who were pathologically diagnosed with HBV-related HCC after hepatectomy. Eligible patients had not received preoperative radiotherapy, chemotherapy, or embolotherapy. Real-time quantitative reverse-transcription polymerase chain reaction was performed to evaluate the expression levels of SEMA6A-AS1 in all tissue specimens. The correless then 0.05). IMPLICATIONS The results show that low expression of SEMA6A-AS1 was associated with a poor prognosis in patients with HBV-related HCC. It is necessary to determine the function and mechanism of SEMA6A-AS1 in HCC in order to identify it as a prognostic biomarker and therapeutic target. This review presents a retrospective analysis of the significance of the contributions of pathologists and kindred investigators in the latter half of the twentieth century to the advancement of understanding of atherosclerosis, a major disease and affliction of humankind. These outstanding investigators contributed importantly to the development of a large body of evidence encompassing population-based autopsy studies, experimental animal studies and cell biological investigations that, coupled with insights from epidemiological studies, serve as the underpinning for the current dominant response to injury theory of atherogenesis. Their collective contributions have been highly meritorious and will remain seminally important into the future. The study investigated the potential for obtaining more accurate spine joint reaction force (JRF) estimates from musculoskeletal models by incorporating dynamic stereo X-ray imaging (DSX)-based in vivo lumbar vertebral rotational and translational kinematics compared to generic, rhythm (RHY)-based kinematics, while also observing the influence of accompanying inputs intervertebral segment stiffness and neutral state. A full-body OpenSim® musculoskeletal model, constructed by combining existing lower- and upper-body models, was driven based on one volunteer's (female; age 25; 60.8 kg; 176 cm) anthropometrics and kinematics from a series of upright standing and straight-legged dynamic lifting tasks. The lumbar spine portion was modified in a step-wise manner to observe effects of (1) RHY vs. DSX lumbar kinematics; (2) No disc (bushing) stiffness (NBS); generic, linear bushing stiffness (LBS); subject-specific nonlinear bushing stiffness (NLBS); (3) Upright standing (UP) vs. Supine (SUP) neutral state; (4) Weight lifted 4.5 kg vs. 13.6 kg. L4L5 JRF from 24 model variations based on combinations of aforementioned parameters were compared. Rhythm-based kinematics without translational components tends to over-predict JRF (31% and 39% for compression and shear, respectively) compared to DSX-based kinematics. Additionally, differences due to accompanying passive stiffness and neutral state choice combinations were even larger (>50%), indicating heightened demand on the quality of these accompanying inputs. The study not only highlights model sensitivity to choices made regarding the three primary inputs-kinematics, passive stiffness and neutral state- separately, but also how interactions between these choices can result in significant variability in joint loading estimates. AIM To investigate possible differences between surgeons and radiologists in selecting optimal photon energy settings from a set of virtual monochromatic dual-energy computed tomography (CT) images for the assessment of bone union in patients with a suspected non-union of the appendicular skeleton. MATERIALS AND METHODS Fifty patients suspected of having bone non-union after operative fracture treatment with a variety of fixation implants were included. Patients were scanned on a dual-source CT machine using 150/100-kVp. Monochromatic images were extracted at 70, 90, 110, 130, 150, and 190 keV. Images were reviewed by 159 orthopaedic trauma surgeons and 12 musculoskeletal radiologists in order to select the best and worst energy setting to assess bone union. Apilimod Furthermore, a confidence score (1-4) was given in selecting the best and worst setting to assess bone union. RESULTS Monochromatic 190 keV images were selected most frequently as the optimal energy in titanium (34.8%), stainless steel (40%), and combined implants of stainless steel and titanium (40.
