Objective: To evaluate whether methylene blue (MB) could minimize the effects of ischemia-reperfusion injury in the nonischemic lung on a lung transplantation rodent model.
Methods: Forty female Sprague-Dawley rats were divided into 20 donors and 20 recipients. The 20 recipient rats were divided into two groups (n = 10) according to the treatment (0.9% saline vs. 1% MB solutions). All animals underwent unilateral lung transplantation. Recipients received 2 mL of saline or MB intraperitoneally prior to transplantation. After 2 h of reperfusion, the animals were euthanized and histopathological and immunohistochemical analyses were performed in the nonischemic lung.
Results: There was a significant decrease in inflammation-neutrophil count and intercellular adhesion molecule-1 (ICAM-1) expression in lung parenchyma were higher in the saline group in comparison with the MB group-and in apoptosis-caspase-3 expression was higher in the saline group and Bcl-2 expression was higher in MB group.
Conclusions: MB is an effective drug for the protection of nonischemic lungs against inflammation and apoptosis following unilateral lung transplantation in rats.

In the Twilight of Evidence: Is Bypass Surgery Still on the Table for Cardiac Allograft Vasculopathy?
J Clin Med

Department of Cardiology, University Hospital Zurich, 8091 Zurich, Switzerland.
Cardiac allograft vasculopathy (CAV) is a major prognosis-limiting factor in patients undergoing orthotopic heart transplantation (HT). Due to the diffuse involvement of the coronary tree, CAV lesions are often not amenable to percutaneous coronary intervention (PCI), leaving coronary artery bypass grafting (CABG) and retransplantation as primary revascularization options. : The latest guidelines from the International Society for Heart and Lung Transplantation (ISHLT) recognize CABG as a viable option but with a downgraded strength of recommendation.

Extracorporeal carbon dioxide removal (ECCOR) is an emerging technique designed to reduce carbon dioxide (CO) levels in venous blood while enabling lung-protective ventilation or alleviating the work of breathing. Unlike high-flow extracorporeal membrane oxygenation (ECMO), ECCOR operates at lower blood flows (0.4-1.

Thoracic malignancies (lung cancers and malignant pleural mesothelioma) are prevalent worldwide and are associated with high morbidity and mortality. Effective treatments are needed for patients with advanced disease. Cell therapies are a promising approach to the treatment of advanced cancers that make use of immune effector cells that have the ability to mediate antitumor immune responses.

Respiratory infections, including tuberculosis, constitute a major global health challenge. Tuberculosis (TB), caused by (Mtb), remains one of the leading causes of mortality worldwide. The disease's complexity is attributed to Mtb's capacity to persist in latent states, evade host immune defenses, and develop resistance to antimicrobial treatments, posing significant challenges for diagnosis and therapy.

We aim to understand the host immunologic and microbial features of COVID-19 in transplant recipients by leveraging a prospective multicenter cohort of 86 transplant recipients age- and sex-matched with 172 non-transplant controls. We find that transplant recipients have higher nasal SARS-CoV-2 viral abundance and impaired viral clearance, and lower anti-spike IgG levels.
