More than a year after the Biological License Application (BLA) approval for CellTrans, cadaveric islet transplantation remains in demise in the United States (U.S.).

Enhancing nursing students' clinical competency using a multi-patient simulation learning model: A randomized controlled study.

Background: For nurses, clinical competency is paramount in ensuring that patients receive safe, high-quality care. Multi-patient simulation (MPS) in nursing education is gaining attention, and evidence shows its suitability for real-life situations. MPS can be an effective solution for nurses' continuing clinical education.

Piperacillin/tazobactam for surgical prophylaxis during pancreatoduodenectomy: meta-analysis.

Background: Pancreatoduodenectomy is associated with an increased incidence of surgical-site infections, often leading to a significant rise in morbidity and mortality. This trend underlines the inadequacy of traditional antibiotic prophylaxis strategies. Hence, the aim of this meta-analysis was to assess the outcomes of antimicrobial prophylaxis, comparing piperacillin/tazobactam with traditional antibiotics.

Modified Radiation Lobectomy Strategy of Radioembolization for Right-Sided Unresectable Primary Liver Tumors.

Purpose: To assess the safety and effectiveness of using modified radiation lobectomy (mRL) to treat primary hepatic tumors located in the right hepatic lobe (Segments V-VIII) and to determine future liver remnant (FLR) hypertrophy.

Materials And Methods: A retrospective review was performed at a single institution to include 19 consecutive patients (7 females, 12 males) who underwent single-session mRL for right-sided primary hepatic tumors: 15 received segmentectomy plus lobectomy (segmental dose of >190 Gy and lobar dose of >80 Gy); 4 were treated with the double-segmental approach (dominant segments of >190 Gy and nondominant segments of >80 Gy). Treated tumors included 13 hepatocellular carcinoma (HCC), 4 cholangiocarcinoma (CCA), and 2 mixed-type HCC-CCA with a median dominant tumor size of 5.

The Seattle Heart Failure Model in Kidney Transplant Recipients.

Cardiovascular disease is the leading cause of mortality following kidney transplantation. Heart failure affects 17-21% of patients with chronic kidney disease and increases along with time receiving dialysis. The Seattle Heart Failure Model (SHFM) is a validated mortality risk model for heart failure patients that incorporates clinical, therapeutic, and laboratory parameters but does not include measures of kidney function.

Fecal metabolite profiling identifies liver transplant recipients at risk for postoperative infection.

Metabolites produced by the intestinal microbiome modulate mucosal immune defenses and optimize epithelial barrier function. Intestinal dysbiosis, including loss of intestinal microbiome diversity and expansion of antibiotic-resistant pathobionts, is accompanied by changes in fecal metabolite concentrations and increased incidence of systemic infection. Laboratory tests that quantify intestinal dysbiosis, however, have yet to be incorporated into clinical practice.

Improve the prediction of liver transplant mortality based on pre-transplant factors: A multi-center study from China: Mortality prediction of LT.

Aims: To designed a new model using pre-transplant data to predict post-transplant mortality for Chinese population and compared its performance to that of existing models.

Methods: In this multicenter study, 544 recipients of liver transplants for non-tumor indications were enrolled in the training group and 276 patients in the validation group. The new Simplified Mortality Prediction Scores (SMOPS) model was compared to the MELD and four existing models using the C-statistic.

Selective internal radiation therapy using yttrium-90 microspheres for treatment of localized and locally advanced intrahepatic cholangiocarcinoma.

Objectives: To evaluate safety and effectiveness of selective internal radiation therapy (SIRT) using yttrium-90 for localized and locally advanced intrahepatic cholangiocarcinoma (iCCA).

Methods: A retrospective review was performed of patients with localized iCCA treated with SIRT at a single institution. Overall survival (OS), local tumor response, progression-free survival (PFS), and toxicity were collected.

Comparing High- and Low-Model for End-Stage Liver Disease Living-Donor Liver Transplantation to Determine Clinical Efficacy: A Systematic Review and Meta-Analysis (CHALICE Study).

Introduction: Various studies have demonstrated that low-Model for End-Stage Liver Disease (MELD) living-donor liver transplant (LDLT) recipients have better outcomes with improved patient survival than deceased-donor liver transplantation (DDLT) recipients. LDLT recipients gain the most from being transplanted at MELD <25-30; however, some existing data have outlined that LDLT may provide equivalent outcomes in high-MELD and low-MELD patients, although the term "high" MELD is arbitrarily defined in the literature and various cut-off scores are outlined between 20 and 30, although most commonly, the dividing threshold is 25. The aim of this meta-analysis was to compare LDLT in high-MELD with that in low-MELD recipients to determine patient survival and graft survival, as well as perioperative and postoperative complications.

Management of Established Small-for-size Syndrome in Post Living Donor Liver Transplantation: Medical, Radiological, and Surgical Interventions: Guidelines From the ILTS-iLDLT-LTSI Consensus Conference.

Small-for-size syndrome (SFSS) following living donor liver transplantation is a complication that can lead to devastating outcomes such as prolonged poor graft function and possibly graft loss. Because of the concern about the syndrome, some transplants of mismatched grafts may not be performed. Portal hyperperfusion of a small graft and hyperdynamic splanchnic circulation are recognized as main pathogenic factors for the syndrome.

Persistence of long-term insulin independence after islet transplantation and two subsequent pregnancies.

Pregnancy increases metabolic demand for insulin and may lead to the exhaustion of intraportally transplanted islets and post-gestational hyperglycemia. To prevent these complications, we implemented preemptive insulin supplementation during two subsequent pregnancies in an insulin-independent islet transplant recipient. This strategy resulted in optimal blood glucose control during the pregnancies, the preservation of the optimal islet graft function and the postpartum maintenance of long-term insulin independence.

Biliary atresia and liver transplantation in the United States: A contemporary analysis.

Background: Biliary atresia (BA) remains the number one indication for paediatric liver transplantation (LT) worldwide but is an uncommon indication for older LT recipients. The impact of recent donor allocation changes, pervasive organ shortage and evolving LT practices on the BA LT population is unknown.

Methods: We identified patients who underwent LT between January 2010 and December 2021 using the UNOS database.

Dynamic evaluation based on acute-on-chronic liver failure predicts survival of patients after liver transplantation: a cohort study.

Background And Aims: Dynamic evaluation of critically ill patients is the key to predicting their outcomes. Most scores based on the Model for End-stage Liver Disease (MELD) and acute-on-chronic liver failure (ACLF) utilize point-in-time assessment. This study mainly aimed to investigate the impact of dynamic clinical course change on post-liver transplantation (LT) survival.

Virtual simulation and problem-based learning enhance perceived clinical and cultural competence of nursing students in Asia: A randomized controlled cross-over study.

Background: Both clinical and cultural competencies are of paramount importance in ensuring patients' safety and high-quality care. While problem-based learning (PBL) is a widely applied pedagogy in nursing education, an emerging technology-based pedagogy, virtual simulation provides a realistic clinical learning experience for students. It can be an effective solution for continuing clinical and cultural learning across countries in the era of the pandemic.

Yttrium-90 Radioembolization and Concomitant Systemic Gemcitabine, Cisplatin, and Capecitabine as the First-Line Therapy for Locally Advanced Intrahepatic Cholangiocarcinoma.

Purpose: To determine the safety and effectiveness of yttrium-90 transarterial radioembolization (TARE) combined with systemic gemcitabine, cisplatin, and capecitabine for the first-line treatment of locally advanced intrahepatic cholangiocarcinoma (iCCA).

Materials And Methods: Data of 13 patients with treatment-naïve, locally advanced iCCA treated with a downstaging protocol using gemcitabine, cisplatin, TARE, and capecitabine were retrospectively reviewed. Overall survival (OS), local tumor response (modified Response Evaluation Criteria in Solid Tumors), progression-free survival (PFS), technical adverse events, and toxicity were measured.

Phase 1 Randomized Trial of Stereotactic Body Radiation Therapy Followed by Nivolumab plus Ipilimumab or Nivolumab Alone in Advanced/Unresectable Hepatocellular Carcinoma.

Purpose: Immunotherapy has emerged as a promising therapeutic option for advanced or unresectable hepatocellular carcinoma (HCC). However, survival remains poor with only a subset of patients deriving benefit. This trial investigated the safety and efficacy of stereotactic body radiation therapy (SBRT) with immunotherapy in HCC.

Relatively Poor Long-term Outcomes Following Liver Transplantation for NASH in the United States.

Background: Nonalcoholic steatohepatitis (NASH) continues to increase in frequency as an indication for liver transplantation (LT). Data on long-term outcomes for these patients are limited. We aimed to compare long-term patient and graft survival in patients undergoing LT for NASH in the United States to other indications.

The Effect of Normothermic Machine Perfusion on the Immune Profile of Donor Liver.

Background: Normothermic machine perfusion (NMP) allows viability assessment and potential resuscitation of donor livers prior to transplantation. The immunological effect of NMP on liver allografts is undetermined, with potential implications on allograft function, rejection outcomes and overall survival. In this study we define the changes in immune profile of human livers during NMP.
