Background: Due to high prevalence of hepatitis B virus (HBV) infection in Taiwan, liver grafts from donors positive for hepatitis B surface antigen (HBsAg) without progressive disease can be effective alternative source of donor organs. This study aims to prove the safety of living donor liver transplantation (LDLT) using HBsAg-positive liver grafts and its long-term outcome.
Material And Methods: We studied 14 consecutive LDLT recipients that received HBsAg-positive grafts from November 2009 to December 2013 for various indications. All donors were chronic HBsAg carriers with normal liver function tests. Median follow-up was 46 months (range, 35-59).
Results: All the donors and recipients recovered well post-transplant with no reactivation of HBV to date. Two of the recipients died due to extra-hepatic recurrence of HCC. At median follow-up of 46 months, 4-year cumulative survival of recipients was 77.38%.
Conclusions: In endemic areas, HBsAg-positive donor organs can clearly be used effectively under viral immunoprophylaxis. HBV disease reactivation does not appear to be a threat even with hepatitis B immunoglobulin (HBIG)-free antiviral monoprophylaxis regimen. This study thus proves the safety and feasibility of the option of using HBsAg-positive grafts in high-prevalence areas.

As a leading cause of morbidity and mortality, fibrosis is the common pathway of various chronic inflammatory diseases in organs and causes death in a large number of patients. It can destroy the structure and function of organs and ultimately lead to organ failure, which is a major cause of disability and death in many diseases. However, the regulatory mechanism of organ fibrosis is not well clear and the lack of effective drugs and treatments, which seriously endangers human health and safety.

Intracardiac migration of inferior vena cava (IVC) filter or stent is a rare but potentially fatal complication of endovascular venous device placement. There is no consensus whether migrated stents should be surgically removed by open cardiac surgery or retrieved by the percutaneous endovascular route and whether an intervention should be performed immediately or expectantly. Herein, we report a 39-year-old female who received emergent left lobe living donor liver transplantation (LDLT) owing to posthepatectomy liver failure.

Objective: The study objective was to assess the efficacity of different surgical strategies for atrioesophageal fistula after catheter ablation of atrial fibrillation.
Methods: Between January 2010 and April 2023, all patients with a diagnosis of atrioesophageal fistula or pericardo-esophageal fistula after catheter ablation of atrial fibrillation were analyzed retrospectively from the French database EPITHOR. Patients without surgical management were excluded.

Objective: To develop a model for preoperatively predicting postcardiotomy cardiogenic shock (PCCS) in patients with poor left ventricular (LV) function undergoing cardiac surgery.
Methods: From the Society of Thoracic Surgeons Adult Cardiac Database, 11,493 patients with LV ejection fraction ≤35% underwent isolated on-pump surgery from 2018 through 2019, of whom 3428 experienced PCCS. In total, 68 preoperative clinical variables were considered in machine-learning algorithms trained and optimized using scikit-learn software.
