Potential association between public medical insurance, waitlist mortality, and utilization of living donor liver transplantation: An analysis of the Scientific Registry of Transplant Recipients.

Background: The Affordable Care Act (ACA) and subsequent Medicaid expansion has increased utilization of public health insurance. Living donor liver transplantation (LDLT) increases access to transplant and is associated with improved survival but consistently represents < 5% of LT in the United States.

Study Design: National registry data were analyzed to evaluate the impact of insurance payor on waitlist mortality and LDLT rates at LDLT centers since implementation of the ACA.

Effects of Coronavirus Disease 2019 on Solid Organ Transplantation.

Background: As the novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has emerged as a viral pandemic, data on the clinical characteristics and outcomes of patients with SARS-CoV-2 infection undergoing solid organ transplant are emerging. The objective of this systematic review was to assess currently published literature relating to the management, clinical course, and outcome of SARS-CoV-2 infection in liver, kidney, and heart solid organ transplant recipients.

Methods: We conducted a systematic review to assess currently published literature relating to the management, clinical course, and outcome of SARS-CoV-2 infection in liver, kidney, and heart solid organ transplant recipients.

SPOT GRADE II: Clinical Validation of a New Method for Reproducibly Quantifying Surgical Wound Bleeding: Prospective, Multicenter, Multispecialty, Single-Arm Study.

The SPOT GRADE (SG), a Surface Bleeding Severity Scale, is a unique visual method for assessing bleeding severity based on quantitative determinations of blood flow. This study assessed the reliability of the SG scale in a clinical setting and collected initial data on the safety and efficacy of HEMOBLAST Bellows (HB), a hemostatic agent, in abdominal and orthopedic operations. Twenty-seven patients were enrolled across 3 centers and received the investigational device.

Rapid Adaptation of a Surgical Research Unit to Conduct Clinical Trials During the COVID-19 Pandemic.

The coronavirus disease 2019 (COVID-19) pandemic has brought most ongoing clinical trials to a standstill, while at the same time emphasizing the need for new therapeutic treatments and strategies to mitigate the morbidity and mortality related to COVID-19. Recent publication of several observational studies has generated much discussion surrounding efficacy of drugs including hydroxychloroquine, azithromycin, and remdesivir, stressing the need for high-quality prospective, randomized control trials in patients with COVID-19. Ongoing "stay at home" orders and institutional policies mandating "work from home" for nonessential employees, which includes most research personnel, have impacted the ability to implement and conduct clinical studies.

Fibrin Sealant Patch (TachoSil) vs Oxidized Regenerated Cellulose Patch (Surgicel Original) for the Secondary Treatment of Local Bleeding in Patients Undergoing Hepatic Resection: A Randomized Controlled Trial.

Background: Local hemostatic agents are important for the control of bleeding during liver resection when standard surgical techniques are insufficient.

Study Design: This was a multicenter, randomized, open-label study to compare fibrin sealant patch (FSP; TachoSil; Takeda Pharma A/S) with oxidized regenerated cellulose gauze (ORCG; Surgicel Original; Ethicon) for the secondary treatment of local bleeding after hepatic resection in adult and pediatric patients. Primary end point was the proportion of adult patients with intraoperative hemostasis at the target bleeding site within 3 minutes of application of treatment.

TLR4 Signaling via NANOG Cooperates With STAT3 to Activate Twist1 and Promote Formation of Tumor-Initiating Stem-Like Cells in Livers of Mice.

Background & Aims: Obesity and alcohol consumption contribute to steatohepatitis, which increases the risk for hepatitis C virus (HCV)-associated hepatocellular carcinomas (HCCs). Mouse hepatocytes that express HCV-NS5A in liver up-regulate the expression of Toll-like receptor 4 (TLR4), and develop liver tumors containing tumor-initiating stem-like cells (TICs) that express NANOG. We investigated whether the TLR4 signals to NANOG to promote the development of TICs and tumorigenesis in mice placed on a Western diet high in cholesterol and saturated fat (HCFD).

Liver transplantation for metastatic neuroendocrine tumors: Outcomes and prognostic variables.

Background: Patient selection for liver transplantation for metastatic neuroendocrine tumors remains a topic of debate. There is no established MELD exception, making it difficult to obtain donor organs.

Methods: A multicenter database was created assessing outcomes for liver and multivisceral transplantation for metastatic neuroendocrine tumors and identifying prognostic factors for survival.

Imaging appearance in acute liver failure: correlation with clinical and pathology findings.

Background And Aim: Acute liver failure (ALF) is characterized by sudden liver injury without underlying chronic liver disease. Excluding underlying cirrhosis in these patients is often difficult and liver biopsy may be impractical. We review the imaging appearance of acute hepatic failure in patients who underwent transplant and correlate these findings with clinical, laboratory and pathology parameters.

Ischemic mass effect from biliary surgical clips.

Migrating surgical clips in the hepatic hilum are known causes of biliary stricture or obstruction, most often due to direct intraluminal obstruction or secondary stone formation. Two cases are reported on patients with previous cholecystectomies presenting with delayed symptoms of biliary tract stricture. Both patients were successfully treated with a resection of the strictured area and a Roux-en-Y hepatico-jejunostomy.

Predictors of employment after liver transplantation.

Employment after orthotopic liver transplantation (OLT) indicates recipients' physical/psychosocial adjustment. Our aim was to determine clinical, socioeconomic and health-related quality of life parameters influencing employment after OLT. Questionnaire on demographics, medical conditions, alcohol and drug use before/after OLT, and a validated 12-Item Short Form Health Survey (SF-12) were mailed to 126 adult OLT patients.

Histologic evaluation and treatment outcome after sequential radiofrequency ablation and hepatic resection for primary and metastatic tumors.

Operative manipulation during hepatic resection (HR) causes tumor cell shedding which is a factor in disease recurrence. Radiofrequency ablation (RFA) causes coagulative necrosis and was used to destroy the tumor before HR. We evaluated tumor necrosis and recurrence of hepatic malignancies treated by sequential RFA/HR.
