Portal vein preparation for inflow anastomosis is a critical step in liver transplantation. Although portal vein thrombosis is well documented and classified according to Yerdel grading, calcification or sclerosis of the portal vein is rarely reported. Segmental or diffuse calcification of portal vein compromises its structural integrity and may even result in flow obstruction, rendering it unsuitable for reconstruction and necessitating alternative inflow strategies. This case report describes a patient with portal vein tearing around chronic calcification who underwent successful living donor liver transplantation using a cryopreserved iliac vein graft anastomosed to gastric varices.

Background: Liver transplantation (LT) is the standard treatment for end-stage liver disease; however, it can lead to biliary strictures in 25%–30% of cases. We aimed to develop a biodegradable stent loaded with paclitaxel that could be inserted during surgery without requiring removal. We evaluated the safety and efficacy of this stent using a porcine model. Methods: Fourteen pigs underwent simulated ischemic injury during LT, and a biodegradable paclitaxel-eluting stent was inserted after duct-to-duct anastomosis.Pigs were divided into four groups: no stent (n=3), bare stent (n=3), 300 µg paclitaxel stent (n=4), and 900 µg paclitaxel stent (n=4). After 3 months of follow-up, autopsies were conducted to obtain common bile duct tissue samples, and inflammation and fibrosis thicknesses were assessed under a microscope. Results: Most tissues had resolved the inflammatory reactions by the 3-month mark. The thinnest fibrosis thickness was observed in the 900 µg group (359.08±167.23 µm); however, no statistical significance was observed. Conclusion This study demonstrated the safety of paclitaxel-eluting biodegradable biliary stents and their positive effects on fibrosis in an ischemic bile duct porcine model. This biodegradable stent represents a potential approach for overcoming the complications associated with biliary strictures after LT.

Objectives: ：This study aimed to explore the association between depression and perceived stress, viral anxiety, reassurance-seeking behavior, and poor sleep quality among the general population in Bangladesh, withself-efficacy as a possible mediator. Methods: ：Data on stress and anxiety during the pandemic in Bangladesh were collected through an online survey from September 16, 2021 to October 4, 2021. Viral anxiety and depression were measured using the Bangla version of Stress and Anxiety to Viral Epidemic-6 (SAVE-6) and Patient Health Questionnaire-9 (PHQ-9), re-spectively. Self-efficacy was measured by the General Self-efficacy (GSE) scale. Reassurance-seeking behavior related to the coronavirus disease 2019 infection was measured by the Coronavirus Reassurance-Seeking Behav-iors Scale (CRBS). Results: ：The CRBS showed a significant correlation with SAVE-6 (r=0.281, p<0.001) and PHQ-9 (r=0.227, p<0.001). People with higher anxiety, reassurance-seeking behavior, and poor sleep quality had lower self-effi-cacy, which led to depression. In contrast, perceived stress increased self-efficacy. The psychological factors im-pacted depression directly as well as indirectly, and self-efficacy mediated the association. Conclusions ：Viral anxiety, reassurance-seeking behavior, perceived stress, and poor sleep quality have a close correlation with depression both directly and indirectly. Self-efficacy can be a mediating factor in the asso-ciation between psychological distress and depression. Viral anxiety, reassurance-seeking behavior, and poorsleep quality reduce self-efficacy. On the other hand, perceived stress can strengthen self-efficacy.

Background: s/Aims: Challenges arise when translating pure laparoscopic donor right hepatectomy (PLDRH) results from Asian to Western donors, due to differences in body mass index (BMI). This study compares the outcomes of PLDRH and conventional open donor right hepatectomy (CDRH) in donors with BMI over 30. Methods: Medical records of live liver donors (BMI > 30) undergoing right hepatectomy (2010−2021) were compared: 25 PLDRH cases vs. 19 CDRH cases. Donor and recipient demographics, operative details, and outcomes were analyzed. Results: PLDRH and CDRH had similar donor and recipient characteristics. PLDRH had longer liver removal and warm ischemic times, but a shorter post-liver removal duration than CDRH. Donor complication rates were comparable, with the highest complication being grade IIIa in PLDRH, necessitating needle aspiration for biloma on postoperative day 11. Fortunately, this donor fully recovered without additional treatment. No complications exceeding Clavien–Dindo grade IIIa occurred in either group. Recipient outcomes between the groups were similar. Conclusions This study supports PLDRH as a viable option for donors with BMI over 30, challenging the notion that high BMI should deter considering PLDRH. The findings provide valuable insights into the safety and feasibility of PLDRH, encouraging further exploration of this technique in diverse donor populations.

Objective: This study identified latent subtypes of mental health literacy (MHL) for Internet gaming disorder (IGD) and explored their characteristics and differences in various factors in adolescents. Methods: This study analyzed secondary data from the 2019 Youth Smart Digital Media Survey and included data from 1,936 middle and high school students (14–18 years old). Thirteen items of the MHL questionnaire were used for latent profile analysis. We compared the characteristics and predictors of the identified types using various statistical analyses, including one-way ANOVA, chi-square test, and multinomial logistic regression. Results: We identified three subtypes of MHL for IGD in adolescents: “low perception-prefer informal resources,” “moderate perception-preferred resources unclear,” and “high perception-prefer professional resources.” Subtypes showed significant differences in sex, age, family affluence, e-learning time during weekdays, mental health risks, level of problematic smartphone use, and IGD. All variables except IGD predicted one or more latent types. Conclusion Practical interventions are required to improve IGD MHL, including customized prevention based on the differences between the three types.
