AI Article Synopsis
- In Japan, there is a lack of research on how deceased donor liver transplantation (DDLT) affects sarcopenia, so this study focused on changes in skeletal muscle mass and quality in 23 patients over time.
- Results indicated significant reductions in skeletal muscle mass during hospitalization, with many patients not recovering to pre-transplant levels one year post-DDLT.
- The study concluded that while DDLT may improve muscle quality, the loss of muscle mass during treatment does not appear to correlate with survival outcomes after transplantation.
Article Abstract
Background: In Japan, there are very few cases of deceased donor liver transplantation (DDLT) and even fewer studies on the effects of DDLT on sarcopenia. This study examined the changes in skeletal muscle mass and quality in DDLT, the factors related to these changes, and survival rates.
Methods: Using computed tomography (CT), we retrospectively measured L3 skeletal muscle index (L3SMI) and intramuscular adipose tissue content (IMAC) at admission, discharge, and 1-year post-DDLT in 23 patients with DDLT from our hospital between 2011 and 2020. We investigated the relationships between changes in L3SMI and IMAC associated with DDLT and between various admission factors and survival.
Results: Patients with DDLT showed significant decreases in L3SMI during hospitalization (P < .05). Although L3SMI tended to increase postdischarge, in 11 (73%) cases, it was lower at 1-year post-DDLT than that on admission. Moreover, decreases in L3SMI during hospitalization were correlated to L3SMI on admission (r = 0.475, P < 0.05). Intramuscular adipose tissue content increased from admission to discharge and decreased 1-year post-DDLT. Admission L3SMI and IMAC were not significantly correlated with survival.
Conclusions: This study suggests that the skeletal muscle mass of DDLT patients decreased during hospitalization and showed a slight tendency to improve after discharge, but the decrease tended to be prolonged. In addition, patients with higher skeletal muscle mass at admission tended to lose more skeletal muscle mass during hospitalization. Deceased donor liver transplantation was identified as a potential contributor to improved muscle quality, whereas skeletal muscle mass and quality on admission did not affect post-DDLT survival.

Hernia

Department of Surgery, Icahn School of Medicine at Mount Sinai, One Gustave L. Levy Place, Box 1259, New York, NY, 10029, USA.
Purpose: While surgeons agree that perioperative field blocks should be performed for open inguinal hernia surgery, there lacks consensus in the minimally invasive context. Prior small-scale randomized trials study pain scores only up to 24 h postoperatively. Thus, we sought to investigate the analgesic benefits of a bupivacaine transversus abdominis plane (TAP) block in the first 4 postoperative days.

Background: Recent technological advances have introduced novel methods for measuring body composition, each with unique benefits and limitations. The choice of method often depends on the trade-offs between accuracy, cost, participant burden, and the ability to measure specific body composition compartments.
Objective: To review the considerations of cost, accuracy, portability, and participant burden in reference and emerging body composition assessment methods, and to evaluate their clinical applicability.
Can We Maintain Muscle Mass on a Plant-Based Diet?
Curr Nutr Rep
January 2025
Department of Internal Medicine, Mayo Clinic, Rochester, MN, USA.
Purpose Of Review: This review aims to determine whether muscle mass and function can be effectively maintained without relying on animal-based protein sources. We evaluate the quality, digestibility, and essential amino acid profiles of plant-based proteins to understand their potential in preventing and managing sarcopenia.
Recent Finding: Recent studies indicate that while animal-based proteins have traditionally been considered the gold standard for supporting muscle protein synthesis, certain plant-based protein blends, fortified with leucine or other essential amino acids, can produce comparable anabolic responses.

Purpose: Sarcopenia is an age-related disease that is related to nutritional intake and chronic low-grade inflammation. The aim of this study was to investigate the association of dietary intake, inflammatory markers and sarcopenia among the community-dwelling older adults.
Methods: A total of 1001 older adults aged 60 and above were recruited.

Background: A decline in skeletal muscle mass and function known as skeletal muscle sarcopenia is an inevitable consequence of aging. Sarcopenia is a major cause of decreased muscle strength, physical frailty and increased muscle fatigability, contributing significantly to an increased risk of physical disability and functional dependence among the elderly. There remains a significant need for a novel therapy that can improve sarcopenia and related problems in aging.
