Background: We conducted this prospective nested case-control study for the hepatic artery and portal vein hemodynamic changes after orthotopic liver transplantation.
Methods: A total 128 cases of orthotropic liver transplantation were analyzed, including 25 cases of ischemic type biliary lesions (ITBL). The portal vein and hepatic artery flow velocities were detected by ultrasound on days 28, 42, and 84 after liver transplantation. In the GLM analysis of Lg(S/D), the P values of Group Effect, Time Effect, and Time×Group were 0.014, 0.376, and 0.008, respectively.
Conclusion: Our results show a relatively reduced hepatic artery S/D in ITBL, especially in extrahepatic ITBL.

Clinical outcomes of COVID-19 infection in liver transplant recipients based on vaccination status.
Front Transplant
January 2025
Section of Transplant Surgery, Washington University School of Medicine, St. Louis, MO, United States.
Background: COVID-19 disease burden has been mitigated by vaccination; however, concerns persist regarding weakened immune responses in liver transplant (LT) recipients. This study investigates COVID-19 outcomes in LT recipients based on vaccination status.
Methods: This single-center retrospective study identified LT recipients with PCR-confirmed COVID-19 infection from 03/01/2020 to 07/31/2023.
Construction of a radiogenomic signature based on endoplasmic reticulum stress for predicting prognosis and systemic combination therapy response in hepatocellular carcinoma.
BMC Cancer

Hepatobiliary Center, The First Affiliated Hospital of Nanjing Medical University, 300 Guangzhou Road, Nanjing, Jiangsu, 210029, People's Republic of China.
Background: Hepatocellular carcinoma (HCC) is one of the most common tumors worldwide. Various factors in the tumor environment (TME) can lead to the activation of endoplasmic reticulum stress (ERS), thereby affecting the occurrence and development of tumors. The objective of our study was to develop and validate a radiogenomic signature based on ERS to predict prognosis and systemic combination therapy response.

Department of General Surgery, The First Affiliated Hospital of Anhui Medical University, Hefei, Anhui, 230022, China.
Background: CA19-9 is a classical tumor marker and plays an important role in the diagnosis of biliary and pancreatic cancer. However, a few cases reported that the tumor maker CA19-9 is abnormally elevated in patients with calculous cholecystitis, but the relation between severity of calculous cholecystitis and serum CA19-9 level are still unknown.
Methods: Total 105 calculous cholecystitis patients from first hospital were collected and divided into high serum CA19-9 group(high group, n = 35) and normal serum CA19-9 group(normal group, n = 70).
Perioperative Variation of Plasma Copeptin and Its Association With Vasopressor Need During Liver Transplantation.
Transplant Proc
January 2025
Nişantaşı University Health Services Vocational School, Department of Anesthesia, Turkey.
Background: Vasopressor usage during liver transplant is related to decreased hepatic flow, graft failure, and mortality. We measured plasma Copeptin levels in liver transplant patients based on vasopressor requirements. We hypothesize that preoperative plasma copeptin measurement helps predict the vasopressor infusion requirement during liver transplantation in preoperative evaluation.

The Kidney Disease: Improving Global Outcomes (KDIGO) 2025 Clinical Practice Guideline for the Evaluation, Management, and Treatment of Autosomal Dominant Polycystic Kidney Disease (ADPKD) represents the first KDIGO guideline on this subject. Its scope includes nomenclature, diagnosis, prognosis, and prevalence; kidney manifestations; chronic kidney disease (CKD) management and progression, kidney failure, and kidney replacement therapy; therapies to delay progression of kidney disease; polycystic liver disease; intracranial aneurysms and other extrarenal manifestations; lifestyle and psychosocial aspects; pregnancy and reproductive issues; pediatric issues; and approaches to the management of people with ADPKD. The guideline has been developed with patient partners, clinicians, and researchers around the world, with the goal to generate a useful resource for healthcare providers and patients by providing actionable recommendations.
