We present the case of a 67-year-old woman with chronic cor pulmonale. She never smoked tobacco and had no other risk factors for pulmonary disease. In developed nations, chronic obstructive lung disease and cor pulmonale are overwhelmingly associated with tobacco use. However, indoor air pollution, most commonly due to burning of solid biomass fuel such as wood, can cause similar clinical syndromes. At our teaching hospital, there is an epidemic of chronic cor pulmonale among nonsmoking women. We attribute this sex predilection to women's greater exposure to wood smoke. Physicians must be cognizant of its risks and counsel patients on prevention strategies such as improved ventilation.

Objective: To investigate the clinical efficacy of thoracoscopic minimally invasive surgery with nickel-titanium shape memory alloy wrap bone plate versus rib periosteal internal fixation in patients with multiple rib fractures (MRF) and flail chest.
Methods: A retrospective analysis was performed on 100 patients with MRF and flail chest treated with thoracoscopic minimally invasive surgery and internal fixation with rib fracture preservation between January 2019 and December 2022, including 54 males and 46 females, aged from 20 to 65 years old, with an average age of (38.0±18.
Lysosomal dysfunction and inflammatory sterol metabolism in pulmonary arterial hypertension.

Vascular inflammation regulates endothelial pathophenotypes, particularly in pulmonary arterial hypertension (PAH). Dysregulated lysosomal activity and cholesterol metabolism activate pathogenic inflammation, but their relevance to PAH is unclear. Nuclear receptor coactivator 7 () deficiency in endothelium produced an oxysterol and bile acid signature through lysosomal dysregulation, promoting endothelial pathophenotypes.

Background: Chronic limb-threatening ischemia (CLTI) in patients with chronic kidney disease (CKD) has a high risk of poor outcomes. We aimed to compare the outcomes of lower extremity revascularization in patients with CLTI stratified by CKD severity in patients enrolled in the prospective, randomized Best Endovascular vs Best Surgical Therapy in Patients with CLTI (BEST-CLI) trial.
Methods: The BEST-CLI trial dataset was queried to categorize patients into three groups according to CKD stage.
Impact of Continuous Positive Airway Pressure on Patient Outcomes in Acute Cardiogenic Pulmonary Edema Within Physician-Led Prehospital Care.

Faculty of Medicine, University of Sarajevo, 71000 Sarajevo, Bosnia and Herzegovina.
Background: CPAP has been shown to be particularly beneficial in the management of acute cardiogenic pulmonary edema by reducing both preload and afterload, thus decreasing the work of breathing and improving oxygenation.
Methods: This study was a prospective observational study, conducted in the period from 2022 to 2024, assessing the effectiveness and safety of prehospital CPAP therapy use in patients with acute cardiogenic pulmonary edema, administered alongside standard care.
Results: In this study, 50 patients with acute cardiogenic pulmonary edema were treated by physician-led emergency teams in the Canton of Sarajevo.
Loss of Type 2 Bone Morphogenetic Protein Receptor Activates NOD-Like Receptor Family Protein 3/Gasdermin E-Mediated Pyroptosis in Pulmonary Arterial Hypertension.

Background: Pulmonary arterial hypertension (PAH) is an incurable disease initiated by endothelial dysfunction, secondary to vascular inflammation and occlusive pulmonary arterial vascular remodeling, resulting in elevated pulmonary arterial pressure and right heart failure. Previous research has reported that dysfunction of type 2 bone morphogenetic protein receptor (BMPR2) signaling pathway in endothelium is inclined to prompt inflammation in PAH models, but the underlying mechanism of BMPR2 deficiency-mediated inflammation needs further investigation. This study was designed to investigate whether BMPR2 deficiency contributes to pulmonary arterial hypertension via the NLRP3 (NOD-like receptor family protein 3)/GSDME (gasdermin E)-mediated pyroptosis pathway.
