Purpose: Acute pulmonary embolism (PE) presents a significant challenge in lung transplant recipients (LTR), even with prophylactic anticoagulation. Due to the heightened risk of complications in this population, the optimal treatment approach for acute PE remains uncertain. This retrospective case series aims to elucidate the outcomes of percutaneous mechanical thrombectomy with the Inari device (MT) and catheter-directed thrombolysis (CDT) in managing acute PE in lung transplant patients.
Materials And Methods: This study examines the treatment outcomes of nine consecutive post-lung transplantation patients with acute PE confirmed with Computed Tomography Angiography (CTA). Treatment interventions included either MT or CDT. Follow-up assessments encompassed a minimum of one year and up to 3 years post-treatment, evaluating various parameters including ICU stay, ventricular pressures, pulmonary function, and laboratory tests.
Results: Both MT and CDT achieved a 100% technical success rate, leading to the successful restoration of pulmonary blood flow and improvements in hemodynamic parameters, with a one-year survival rate of 100%.
Conclusion: Percutaneous treatments, including MT and CDT, demonstrate feasibility and efficacy in managing acute PE among lung transplant patients. These treatments lead to rapid thrombus resolution, post-treatment improvements, and enhanced overall survival.

While immunotherapy has shown some efficacy in lung adenocarcinoma (LUAD) patients, many respond only partially or not at all. One limitation in improving outcomes is the lack of a complete understanding of immune checkpoint regulation. Here, we investigated a possible link between an environmental chemical receptor implicated in lung cancer and immune regulation, the AhR, a known but counterintuitive mediator of immunosuppression (interferon (IFN)-γ), and regulation of two immune checkpoints (PD-L1 and IDO).

Background And Aims: The severe alpha-1 antitrypsin deficiency (AATD) genotype Pi*ZZ increases the risk of liver disease (AATD-LD) and lung disease. While non-invasive tests (NITs) are widely used for fibrosis stage and monitoring of all liver diseases, the consensus for use in AATD-LD is limited. A Delphi panel study was conducted to address this need.

Introduction: Globally, lung cancer is one of the most commonly diagnosed cancers and continues to take the lead in cancer-related mortality rates. This study aims to provide the latest statistics on the clinical, histopathological, and epidemiological features of lung cancer patients who underwent surgical resection in referral hospitals in Southern Iran.
Method: In this retrospective study, records of all patients with operable primary and secondary lung cancer who underwent surgical resection of the lung in Shiraz hospitals, located in Southern Iran from November 2009 to May 2022 were screened.

Background: Lung transplantation (LTx) is the definitive treatment for end-stage pulmonary diseases, with venoarterial extracorporeal membrane oxygenation (VA-ECMO) used as a common perioperative support. However, it remains unclear if central (cVA-ECMO) or peripheral (pVA-ECMO) cannulation routes yield better outcomes in postoperative prognosis. This study compares the impact of these two cannulation strategies on primary graft dysfunction (PGD) incidence in LTx patients.
