Negative Pressure Ventilation Ex-Situ Lung Perfusion Preserves Porcine and Human Lungs for 36-Hours.

Clin Transplant

January 2025

Division of Cardiac Surgery, Department of Surgery, Faculty of Medicine, University of Alberta, Edmonton, Canada.

Introduction: Preclinically, 24-hour continuous Ex-Situ Lung Perfusion (ESLP) is the longest duration achieved in large animal models and rejected human lungs. Here, we present our 36-hour Negative Pressure Ventilation (NPV)-ESLP protocol applied to porcine and rejected human lungs.

Methods: Five sets of donor domestic pig lungs (45-55 kg) underwent 36-hour NPV-ESLP.

CYP2C19 Genotype-Guided Antiplatelet Therapy and Clinical Outcomes in Patients Undergoing a Neurointerventional Procedure.

Clin Transl Sci

January 2025

Division of Pharmacotherapy and Experimental Therapeutics, UNC Eshelman School of Pharmacy, University of North Carolina at Chapel Hill, Chapel Hill, North Carolina, USA.

In neurovascular settings, including treatment and prevention of ischemic stroke and prevention of thromboembolic complications after percutaneous neurointerventional procedures, dual antiplatelet therapy with a P2Y12 inhibitor and aspirin is the standard of care. Clopidogrel remains the most commonly prescribed P2Y12 inhibitor for neurovascular indications. However, patients carrying CYP2C19 no-function alleles have diminished capacity for inhibition of platelet reactivity due to reduced formation of clopidogrel's active metabolite.

In clinical practice, the impact of procedural or patient-related risk factors on 1-year clinical outcomes in patients receiving 1-month of dual antiplatelet therapy (DAPT) followed by P2Y12 inhibitor monotherapy after contemporary percutaneous coronary intervention (PCI) remains unclear. Using data from the multi-center REIWA registry which included patients treated with thin-strut biodegradable polymer drug-eluting stent (BP-DES) and 1-month DAPT followed by P2Y12 inhibitor monotherapy, we assessed the primary endpoint (a composite of cardiovascular death, myocardial infarction, definite stent thrombosis, ischemic or hemorrhagic stroke, and major or minor bleeding) in patients with and without procedural (treatment of three vessels, three or more lesions, three or more stents, bifurcation with two stents, long stenting, and target of chronic total occlusion) and patient-related risk factor (renal insufficiency, anemia, peripheral vascular disease, prior or current history of heart failure and advanced age of ≥ 75 years). Among the 1,202 patients who underwent complete revascularization by PCI, 276 (23.
