Hepatic ischemia-reperfusion injury (IRI) represents a major risk factor of early graft dysfunction and acute/chronic rejection as well as a key obstacle to expanding the donor pool in orthotopic liver transplantation (OLT). Although glucocorticoid receptor (GR) signaling may enhance cytoprotective programs, clinical use of glucocorticoid is limited due to adverse effects, while clinical relevance of GR-facilitated cytoprotection in OLT remains unknown. We aimed to evaluate the significance of hepatic GR in clinical OLT and verify the impact of recombinant human relaxin (rhRLX), which may function as GR agonist in tissue/disease-specific manner...

BACKGROUND: Cone beam computed tomography (CBCT) for radiotherapy image guidance suffers from respiratory motion artifacts. This limits soft tissue visualization and localization accuracy, particularly in abdominal sites. We report on a prospective study of respiratory motion-corrected (RMC)-CBCT to evaluate its efficacy in localizing abdominal organs and improving soft tissue visibility at end expiration. MATERIAL AND METHODS: In an IRB approved study, 11 patients with gastroesophageal junction (GEJ) cancer and five with pancreatic cancer underwent a respiration-correlated CT (4DCT), a respiration-gated CBCT (G-CBCT) near end expiration and a one-minute free-breathing CBCT scan on a single treatment day...

BACKGROUND: The Collaborative Wilms Tumour (WT) Africa Project has implemented an adapted WT treatment guideline in sub-Saharan Africa as a multi-centre prospective clinical trial. A retrospective, baseline evaluation of end-of-treatment outcome was performed for a 2-year period prior to the introduction of this guideline. The collaborative project aims to reduce both treatment abandonment and death during treatment to less than 10% for improving survival. PROCEDURE: All participating centres obtained local Institutional Research Board (IRB) approval and implemented the adapted WT treatment guideline...

In response to researcher concerns a number of initiatives have been developed to support individual researchers seeking ethics review and approval. In this issue, Sonne et al. (2017) outline an example of an intervention to support researchers, which they refer to as a Regulatory Knowledge Support (RKS) service. While the study points to potential benefits, other studies have not had the desired impact on key performance measures. There is a need to develop a community of practice and expand the burgeoning evidence base regarding what interventions work, for whom, and under what circumstances...

Over the past ten years, medical students have increased their research activity to be competitive for orthopaedic residency positions throughout the country. This increase may favor students at institutions with a strong history of research production and well-established research departments with supporting staff. To compete with these institutions, a Musculoskeletal Research Committee was developed at a southern academic institution to provide a mutually beneficial link between orthopaedic research faculty and medical students...

We evaluated the impact of a regulatory support service (known as the Regulatory Knowledge and Support [RKS] program), part of the Medical University of South Carolina's Clinical and Translational Science Award, on the success of Institutional Review Board (IRB) applications that have previously been deemed by the IRB to be Not Ready for Review (NRR). At the time of this evaluation, 77 studies had been deemed NRR, 53 of which came from trainees and junior faculty. All the applications that received regulatory support either received IRB approval or were deemed to not be research, and therefore did not require IRB review...

Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) provides mechanical circulatory support for patients with advanced cardiogenic shock, facilitating myocardial recovery and limiting multi-organ failure. In patients with severely limited left ventricular ejection, peripheral VA-ECMO can further increase left ventricular and left atrial pressures (LAP). Failure to decompress the left heart under these circumstances can result in pulmonary edema and upper body hypoxemia, that is, myocardial and cerebral ischemia...

BACKGROUND: Reduced fertility is a common potential problem among males with congenital adrenal hyperplasia (CAH), with nearly half experiencing impaired sperm production. The major cause of oligo/azoospermia in CAH is testicular adrenal rest tumors (TARTs). Studies indicate that ultrasound screening for TARTs should begin during childhood, yet it remains unclear whether boys with CAH are routinely screened for TARTs and/or counseled about infertility risk and potential interventions such as fertility testing and/or preservation...

BACKGROUND: Long segment occlusive disease in the superficial femoral artery remains a treatment challenge despite advances in open surgical and endovascular approaches. We report initial clinical results of an entirely new procedure to perform femoropopliteal bypass using the DETOUR System to create a stentgraft bypass which originates in the SFA, travels through the femoral vein, and ends in the popliteal artery, bypassing the diseased segment. METHODS: Review the initial results of the first five patients at a single site enrolled in IRB-approved, prospective clinical study using the DETOUR System...

INTRODUCTION: The practice of positioning patients' arms above the head during catheter-injected hepatic arterial phase cone beam CT (A-CBCT) imaging has been inherited from standard CT imaging due to image quality concerns, but interrupts workflow and extends procedure time. We sought to assess A-CBCT image quality and artifacts with arms extended above the head versus down by the side. METHODS: We performed an IRB approved retrospective evaluation of reformatted and 3D-volume rendered images from 91 consecutive A-CBCTs (43 arms up, 48 arms down) acquired during hepatic tumor arterial embolization procedures...

OBJECTIVES: Extramammary Paget disease (EMPD) of the vulva is a rare lesion with a high recurrence rate ranging from 12% to 61%. The rate of underlying adenocarcinoma varies, but in the largest series was reported at 4%. Given the rarity of the disease there is a paucity of data to optimize treatment. This study aims to describe the management and recurrence patterns in a tertiary care setting and to offer suggestions for management in a modern-day setting. METHODS: Patients with pathologically confirmed EMPD treated from 2000 to 2015 were retrospectively identified using an IRB approved database...
