Authors: Rankin KC, O'Brien LC, Gorgey AS Abstract OBJECTIVE: To determine whether dual energy x-ray absorptiometry (DXA) compared to magnetic resonance imaging (MRI) may accurately quantify trunk lean mass (LM) after chronic spinal cord injury (SCI) and to investigate the relationships between trunk LM, visceral adiposity, trunk fat mass and basal metabolic rate (BMR). DESIGN: Cross-sectional design and correlational analysis. SETTING: Research setting in a medical center. PARTICIPANTS: Twenty-two men with motor complete paraplegia (n = 14; T4-T11) and tetraplegia (n = 8; C5...

CONCLUSION: This study suggests Skype has potential for use in remote provision of clinical supervision and case review, and also to support delivery of supervision and clinical services where translation is required. However, further research evaluating the benefit of telesupervision from the perspectives of both the supervisor and supervisee is necessary to determine if it is a sustainable process for practitioners servicing families with complex needs. Impact statement: Skype has potential as an effective technology for supporting availability of high quality supervision by distance and in cross-cultural environments. ...

ABSTRACT The increased risk of Richter transformation (RT) in patients with chronic lymphocytic leukemia (CLL) due to Epstein‐Barr virus (EBV) reactivation during immunosuppressive therapy with fludarabine or other targeted agents remains controversial. Among 31 RT cases classified as diffuse large B‐cell lymphoma (DLBCL), seven (23%) showed EBV expression. In comparison to EBV‐negative tumors, EBV+ DLBCLs derived predominantly from IGVH‐hypermutated CLL and exhibited CLL‐unrelated IGVH sequences more frequently. Intriguingly, despite having different cellular origins, clonally related and unrelated EBV+ DLBCLs s...

Abstract AimsNeoadjuvant chemotherapy (NAC) remains an important therapeutic option for advanced oesophageal cancer (OC). Pathological tumour regression grade (TRG) may offer additional information by directing adjuvant treatment and/or follow‐up but clinical value remains unclear. We analysed the prognostic value of TRG and associated pathological factors in OC patients enrolled in the Medical Research Council OE02 trial. MethodsHistopathology was reviewed in 497 resections from OE02 trial participants randomised to surgery (S‐group;n=244) or NAC followed by surgery (CS‐group;n=253). The association between TRG grou...

Conclusions: To our knowledge, this is the largest cohort studied for the safety of postoperative MRIs, and the only exclusively pediatric study. Based on these findings, we conclude that orthopaedic implants can safely be imaged in the immediate postoperative period.

This study aimed to assess the outcomes of repairing posterolateral meniscal (PLM) root avulsion and para-root tear in association with anterior cruciate ligament (ACL) reconstruction and compare with those whose PLM tear was left untreated. Methods: Patients with PLM root avulsion or para-root tear accompanying ACL tear were evaluated for eligibility. Group A was composed of patients whose ACL tears were reconstructed without any lateral meniscal repair (33 patients) from 2006-2009. From 2009-2012, patients had ACL reconstruction and additional PLM repair (group B: 40 patients). Both groups were evaluated for knee stab...

Background: Comparison of pedicle screw placement accuracy and risk of perioperative complications using O-arm/Stealth Navigation system (Medtronic, Memphis, TN) compared with the free-hand technique for multilevel posterior instrumented thoracolumbar fusion is an actual problem. Methods: A retrospective, single-institution case series study was performed. Patients who underwent multilevel instrumented thoracolumbar fusion between 2011 and 2012 were included; age:>20 yr; gender: male and female. Patients with pedicle screw placement assisted by the O-arm navigation were assigned to the navigated group, while...
