Diagnostic Value of the Alveolar-Arterial Oxygen Gradient in Pulmonary Embolism: A Cross-Sectional Study.
Healthcare (Basel)
December 2024
School of Medicine, University of Split, 21000 Split, Croatia.
: Pulmonary embolism (PE) is a potentially serious condition characterized by the blockage of blood vessels in the lungs, often presenting significant diagnostic challenges due to its non-specific symptoms. This study aimed to evaluate the utility of the alveolar-arterial (A-a) oxygen gradient as a diagnostic tool for PE, hypothesizing that it could enhance early detection when combined with other clinical markers. : We retrospectively analyzed 168 patients at the University Hospital Center Split.

Toronto Lung Transplant Program, Toronto General Hospital, Toronto, Canada.
Ex vivo lung perfusion (EVLP) is used to evaluate donor lungs prior to lung transplantation. Development of pulmonary edema during EVLP is generally thought to represent inflammatory breakdown of the air-fluid barrier and these lungs are declined for transplant. We present the case of a donor lung that underwent stapled wedge resection during cold storage for air leak and the subsequent development of profound (∼650 mL) pulmonary edema around the staple line during EVLP.

J Pediatr Endocrinol Metab

Department of Pediatric Metabolism and Ankara University Rare Diseases Application and Research Center, Ankara University Faculty of Medicine, Ankara, Türkiye.
Objectives: Niemann-Pick type C (NPC) is a rare, autosomal recessive, neurodegenerative disorder caused by biallelic pathogenic variants in the or genes, leading to lysosomal lipid accumulation. NPC has an incidence of 1 in 100,000 live births and presents with a wide range of symptoms affecting visceral organs and the central nervous system. We aim to describe the diverse clinical presentations of NPC through case studies.

January 2025
Department of Anaesthesiology, The Third People's Hospital of Chengdu, Chengdu, China.
Background: Lung ultrasound-guided alveolar recruitment manoeuvres (RMs) may reduce the lung ultrasound score. However, whether the use of this strategy can reduce the incidence of postoperative pulmonary complications (PPCs) in the adult obese population has not yet been tested.
Methods/design: This is a single-centre, two-arm, prospective, randomised controlled trial.
An integrated investigation of mitochondrial genes in COPD reveals the causal effect of NDUFS2 by regulating pulmonary macrophages.
Biol Direct
January 2025
Key Laboratory of Geriatrics of Jiangsu Province, Department of Geriatrics, The First Affiliated Hospital of Nanjing Medical University, 300 Guangzhou Road, Nanjing, 210029, Jiangsu, China.
Background: Despite the increasing body of evidence that mitochondrial activities implicate in chronic obstructive pulmonary disease (COPD), we are still far from a causal-logical and mechanistic understanding of the mitochondrial malfunctions in COPD pathogenesis.
Results: Differential expression genes (DEGs) from six publicly available bulk human lung tissue transcriptomic datasets of COPD patients were intersected with the known mitochondria-related genes from MitoCarta3.0 to obtain mitochondria-related DEGs associated with COPD (MitoDEGs).
