Background: In pediatric living-donor lobar lung transplantation, whether transplanting adult lobes could result in satisfactory long-term survival and respiratory functional outcomes during and after the growth period in pediatric patients remains unclear. This study aimed to evaluate the long-term survival and functional prognosis after pediatric living-donor lobar lung transplantation and deceased-donor lung transplantation.
Methods: We retrospectively reviewed clinical data of pediatric patients (age: ≤17 years) who underwent lung transplantation between March 2001 and December 2022 at three institutions in Japan.
Results: Seventy and 24 patients who underwent living-donor and deceased-donor transplantation, respectively, were included. The 5-year and 10-year overall survival rates were 84.6% and 75.0% after living-donor transplantation and 85.8% and 85.8% after deceased-donor transplantation (p = 0.75), respectively. With a median follow-up period of 89.2 months, 48 living-donor cases (100%) and 16 deceased-donor cases (84.2%) had performance status 0-2 among 48 living-donor cases and 19 deceased-donor cases who were alive without re-transplantation. They showed height growth (median +9.7 cm, p < 0.01); however, the height standard deviation score decreased after transplantation (median -0.22, p = 0.03). The difference in height standard deviation score between the last follow-up and pre-transplantation was negative (median -0.42) in living-donor cases and significantly smaller than that in deceased-donor cases (median +0.19, p = 0.02).
Conclusions: Pediatric living-donor lobar lung transplantation provided satisfactory long-term survival and functional prognosis that were comparable to those of deceased-donor lung transplantation. The limited post-transplant height growth in living-donor cases might be attributed to this favorable functional prognosis.

Background: Mycobacterium avium complex (MAC) is a common pathogen causing non-tuberculous mycobacterial infections, primarily affecting the lungs. Disseminated MAC disease occurs mainly in immunocompromised individuals, such as those with acquired immunodeficiency syndrome, hematological malignancies, or those positive for anti-interferon-γ antibodies. However, its occurrence in solid organ transplant recipients is uncommon.

Background: Aging increases disease susceptibility and reduces vaccine responsiveness, highlighting the need to better understand the aging immune system and its clinical associations. Studying the human immune system, however, remains challenging due to its complexity and significant inter-individual variability.
Methods: We conducted an immune profiling study of 550 elderly participants (≥60 years) and 100 young controls (20-40 years) from the RESIST Senior Individuals (SI) cohort.

(1) Background: Ex Vivo Lung Perfusion (EVLP) is a technique designed to assess and recondition marginal lungs, potentially expanding the donor pool and improving transplant outcomes (2) Methods: This retrospective study evaluated lung transplantation outcomes after EVLP. Donor lungs were assessed using the Toronto protocol, with data on hemodynamics, gas exchange, and perfusion parameters collected and analyzed. Post-transplant complications and survival rates were also examined.

Background: Despite kidney transplantation being a life-saving procedure, patients experience a high risk of developing fungal infections (FIs), with an increased risk of both morbidity and mortality, especially during the first year after transplant.
Methods: We herein conducted a narrative review of the most common FIs in kidney transplant recipients (KTRs), with a focus on prevalence, risk factors, mortality, and prevention strategies.
Results: The most common fungal pathogens in KTRs include species (up to 70% of the overall FIs), species, , and species.

Background/objective: Metabolic syndrome (MetS) is characterized by abdominal obesity, increased blood pressure (BP), fasting blood glucose (FBG) and triglyceride levels, and reduced high-density lipoprotein (HDL) levels. This study aims to investigate the efficacy of the Wharton's jelly mesenchymal stem cells (WJMSCs)-derived small extracellular vesicles' (sEVs) preparations in managing MetS.
Method: Twenty-four rats were fed with a high-fat and high-fructose diet to induce MetS for 16 weeks and randomized into three groups ( = 8/group): a MetS Control group treated with normal saline, MetS Low Dose (LD) group treated with a LD of sEVs preparations (3 × 10 particle/rat), and MetS High Dose (HD) group treated with a HD of sEVs preparations (9 × 10 particles/rat).
