The Current State of Liver Transplantation for Colorectal Liver Metastases in the United States: A Call for Standardized Reporting.

Background: Current success in transplant oncology for select liver tumors, such as hepatocellular carcinoma, has ignited international interest in liver transplantation (LT) as a therapeutic option for nonresectable colorectal liver metastases (CRLM). In the United States, the CRLM LT experience is limited to reports from a handful of centers. This study was designed to summarize donor, recipient, and transplant center characteristics and posttransplant outcomes for the indication of CRLM.

Differential Function and Maturation of Human Stem Cell-Derived Islets After Transplantation.

Insulin-producing stem cell-derived islets (SC-islets) provide a virtually unlimited cell source for diabetes cell replacement therapy. While SC-islets are less functional when first differentiated in vitro compared to isolated cadaveric islets, transplantation into mice has been shown to increase their maturation. To understand the effects of transplantation on maturation and function of SC-islets, we examined the effects of cell dose, transplantation strategy, and diabetic state in immunocompromised mice.

Big Data in Transplantation Practice-the Devil Is in the Detail-Fontan-associated Liver Disease.

Background: As a result of the Fontan procedure, the prognosis of congenital single-ventricle heart disease has improved, with many affected children surviving into adulthood. However, the unanticipated consequences of chronic exposure to Fontan hemodynamics have revealed a new set of secondary noncardiac complications. Fontan-associated liver disease (FALD) is characterized by progressive hepatic fibrosis in nearly all patients post-Fontan, with the potential to develop cirrhosis, hepatocellular carcinoma, and the need for liver transplantation.

Gene-edited human stem cell-derived β cells from a patient with monogenic diabetes reverse preexisting diabetes in mice.

Differentiation of insulin-producing pancreatic β cells from induced pluripotent stem cells (iPSCs) derived from patients with diabetes promises to provide autologous cells for diabetes cell replacement therapy. However, current approaches produce patient iPSC-derived β (SC-β) cells with poor function in vitro and in vivo. Here, we used CRISPR-Cas9 to correct a diabetes-causing pathogenic variant in Wolfram syndrome 1 () in iPSCs derived from a patient with Wolfram syndrome (WS).

Long-Term Financial, Psychosocial, and Overall Health-Related Quality of Life After Living Liver Donation.

Background: To assess the impact of living liver donation (LD) in a diverse and aging population up to 20 y after donation, particularly with regard to medical, financial, psychosocial, and overall health-related quality of life (HRQOL).

Methods: Patients undergoing LD between 1999 and 2009 were recruited to respond to the Short-Form 36 and a novel Donor Quality of Life Survey at two time points (2010 and 2018).

Results: Sixty-eight living liver donors (LLDs) completed validated surveys, with a mean follow-up of 11.

Immunologic benefit of maternal donors in pediatric living donor liver transplantation.

Purpose Of Review: Long-term follow-up has suggested that pediatric LDLT may have superior outcomes compared to deceased donor recipients. In this review, we describe the subset of LDLT recipients with maternal donors that have lower reported rates of rejection and improved allograft survival.

Recent Findings: Pediatric LDLT recipients, particularly those with a primary diagnosis of biliary atresia who receive grafts from their mothers, have been reported to have lower rates of acute cellular rejection post-transplant and graft failure.

Myogenic Akt signaling attenuates muscular degeneration, promotes myofiber regeneration and improves muscle function in dystrophin-deficient mdx mice.

Duchenne muscular dystrophy, the most common form of childhood muscular dystrophy, is caused by X-linked inherited mutations in the dystrophin gene. Dystrophin deficiencies result in the loss of the dystrophin-glycoprotein complex at the plasma membrane, which leads to structural instability and muscle degeneration. Previously, we induced muscle-specific overexpression of Akt, a regulator of cellular metabolism and survival, in mdx mice at pre-necrotic (<3.

Myogenic Akt signaling upregulates the utrophin-glycoprotein complex and promotes sarcolemma stability in muscular dystrophy.

Duchenne muscular dystrophy is caused by dystrophin mutations that lead to structural instability of the sarcolemma membrane, myofiber degeneration/regeneration and progressive muscle wasting. Here we show that myogenic Akt signaling in mouse models of dystrophy promotes increased expression of utrophin, which replaces the function of dystrophin thereby preventing sarcolemma damage and muscle wasting. In contrast to previous suggestions that increased Akt in dystrophy was a secondary consequence of pathology, our findings demonstrate a pivotal role for this signaling pathway such that modulation of Akt can significantly affect disease outcome by amplification of existing, physiological compensatory mechanisms.

Sinomenine suppresses TNF-alpha-induced VCAM-1 expression in human umbilical vein endothelial cells.

Sinomenine (SN), an alkaloid prepared from the root of Sinomenium acutum Rehd. Et wils, is used to alleviate the symptoms of rheumatism in Chinese medicine. In the present study, the potential inhibition of TNF-alpha-induced VCAM-1 expression on human umbilical vein endothelial cells (HUVECs) was evaluated in vitro.

Association of increased interferon-inducible gene expression with disease activity and lupus nephritis in patients with systemic lupus erythematosus.

Objective: To study 5 type I interferon (IFN)-inducible genes (LY6E, OAS1, OASL, MX1, and ISG15) in patients with systemic lupus erythematosus (SLE) and to correlate expression levels with disease activity and/or clinical manifestations.

Methods: Peripheral blood cells were obtained from 48 SLE patients, 48 normal controls, and 22 rheumatic disease controls, and total RNA was extracted and reverse transcribed into complementary DNA. Gene expression levels were measured by real-time polymerase chain reaction, standardized to a housekeeping gene, and summed to an IFN score.
