Sleeve resection, a mainstay for centrally-located lung cancer, is a challenging procedure when the preserved lung is impaired. We herein reported a 61-year-old male who underwent right upper sleeve lobectomy for squamous cell carcinoma located at the orifice of the upper bronchus. The tumor invaded the main bronchus. A lung perfusion scan showed severe impairment, while the right middle and lower lobes were well expanded. Not only the spirogram, but also the lung perfusion in the residual lung, had markedly recovered at 2 months after the right upper extended sleeve lobectomy. The patient is currently living his normal daily life. Residual lung perfusion can be revived, even if it is impaired preoperatively.

Objectives: To analyse the effects on respiratory function, lung volume and the regional distribution of ventilation and perfusion of routine postural repositioning in mechanically ventilated critically ill patients.
Methods: Prospective descriptive physiological study. We evaluated gas-exchange, lung mechanics, and Electrical Impedance Tomography (EIT) determined end-expiratory lung impedance and regional ventilation and perfusion distribution in five body positions: supine-baseline (S1); first lateralisation at 30° (L1); second supine position (S2), second contralateral lateralisation (L2) and third final supine position (S3).

Objectives: To conduct a meta-analysis of the diagnostic performance of non-contrast magnetic resonance pulmonary angiography (NC-MRPA) and ventilation-perfusion (V/Q) scintigraphy for the detection of acute pulmonary embolism (PE).
Materials And Methods: Systematic searches of electronic databases were conducted from 2000 to 2024. Primary outcomes were per-patient sensitivity and specificity of NC-MRPA and V/Q scintigraphy.

Pulmonary vascular diseases, particularly when accompanied by pulmonary hypertension, are complex disorders often requiring multimodal imaging for diagnosis and monitoring. Echocardiography is the primary screening tool for pulmonary hypertension, while cardiac MR imaging (CMR) is used for more detailed characterization and risk stratification in right ventricular failure. Chest computed tomography (CT) is used to detect vascular anomalies and parenchymal lung diseases.

(1) Background: Ex Vivo Lung Perfusion (EVLP) is a technique designed to assess and recondition marginal lungs, potentially expanding the donor pool and improving transplant outcomes (2) Methods: This retrospective study evaluated lung transplantation outcomes after EVLP. Donor lungs were assessed using the Toronto protocol, with data on hemodynamics, gas exchange, and perfusion parameters collected and analyzed. Post-transplant complications and survival rates were also examined.

We investigated the role of uric acid in the pathogenesis of severe malaria (SM) in two independent cohorts of children with SM. Hyperuricemia (blood uric acid ≥ 7 mg dl) was present in 25% of children with SM and was associated with increased in-hospital mortality and postdischarge mortality in both cohorts. Increased blood uric acid levels were also associated with worse scores in overall cognition in children with SM < 5 years old in both cohorts.
