Biliary atresia susceptibility gene EFEMP1 regulates extrahepatic bile duct elastic fiber formation and mechanics.

Background & Aims: EGF-containing fibulin extracellular matrix protein 1 (EFEMP1, also called fibulin-3) is an extracellular matrix protein linked in a genome-wide association study to biliary atresia, a fibrotic disease of the neonatal extrahepatic bile duct. Fibulin-3 is deposited in most tissues and null mice have decreased elastic fibers in visceral fascia; however, fibulin-3 does not have a role in the development of large elastic fibers and its overall function in the extrahepatic bile ducts remains unclear.

Methods: We used staining and histology to define the amount and organization of key extracellular matrix components in the extrahepatic bile ducts.

Microcystin-RR is a biliary toxin selective for neonatal extrahepatic cholangiocytes.

Background & Aims: Biliary atresia is a fibrosing cholangiopathy affecting neonates that is thought to result from a prenatal environmental insult to the bile duct. Biliatresone, a plant toxin with an α-methylene ketone group, was previously implicated in biliary atresia in Australian livestock, but is found in a limited location and is unlikely to be a significant human toxin. We hypothesized that other unsaturated carbonyl compounds, some with the potential for significant human exposure, might also be biliary toxins.

Use of Intraoperative Doppler Ultrasonography in Predicting Life-Threatening Vascular Complications After Adult Deceased Donor Liver Transplantation.

Aim This study aims to determine if routine use of intraoperative Doppler ultrasonography is preventative of life-threatening vascular complications (VCs) after orthotopic liver transplantation. Methods This single-center, retrospective study reviewed all adult orthotopic liver transplants at Saint Louis University Hospital from 2015 to 2020 (N = 188). The sample population consists of men and women in the age range of 18 to 75.

Exploring Spiritual Concerns, Needs, and Resources in Outpatient Healthcare Facilities Serving Under-Resourced Black Patients: A Qualitative Study.

Background: Acknowledging patients' spiritual concerns can enhance well-being and is essential to patient-centered chronic illness care. However, unmet spiritual care needs remain a major area of suffering, particularly among under-resourced populations. Limited research exists on how spiritual concerns are acknowledged and integrated into the care of chronically ill older Black patients in these settings.
