Objective: To describe the beneficial clinical effect of the use of surfactant in a patient with severe unilateral pulmonary hemorrhage after iatrogenic lung injury during corrective surgery for congenital heart defects.
Design: Case report.
Setting: Pediatric cardiac intensive care unit of a tertiary care hospital.
Patient: An 11-wk-old boy.
Interventions: Intratracheal instillation of 4 mL (100 mg) of surfactant (Survanta) per kilogram of body weight to treat profound and refractory hypoxia and hypercapnia despite high-ventilation pressures, high respiratory rate, and the use of nitric oxide caused by severe pulmonary hemorrhage and atelectasis.
Measurements And Main Results: The aggressive ventilation variables could be reduced within the following 2 hrs after surfactant use (from Fio2 0.8, peak inspiratory pressure 36 cm, positive end-expiratory pressure 10 cm, respiratory rate 50, tidal volume 63 mL, and nitric oxide 10 ppm to Fio2 0.4, peak inspiratory pressure 28 cm, positive end-expiratory pressure 10, respiratory rate 40, tidal volume 38 mL, and nitric oxide 5 ppm). There was rapid improvement of clinical variables (inotropic support, chest radiograph) as well as oxygenation (Pao2 from 56 to 149 mm Hg), CO2 exchange (Paco2 from 85 to 39 mm Hg), and acidosis (from pH 7.13 to 7.44).
Conclusions: The administration of surfactant may be a promising approach to treat severe respiratory failure caused by severe pulmonary hemorrhage.

Background: Acute pulmonary embolism represents the third most prevalent cardiovascular pathology, following coronary heart disease and hypertension. Its untreated mortality rate is as high as 20-30%, which represents a significant threat to patient survival. In view of the current lack of real-time monitoring techniques for acute pulmonary embolism, this study primarily investigates the potential of the pulsatility electrical impedance tomography (EIT) technique for the detection and real-time monitoring of acute pulmonary embolism through the collection and imaging of the pulsatile signal of pulmonary blood flow.

Background: Recent advancements in contemporary therapeutic approaches have increased the survival rates of lung cancer patients; however, the long-term benefits remain constrained, underscoring the pressing need for novel biomarkers. Surfactant-associated 3 (SFTA3), a long non-coding RNA predominantly expressed in normal lung epithelial cells, plays a crucial role in lung development. Nevertheless, its function in lung adenocarcinoma (LUAD) remains inadequately understood.

Background: Esophageal ultrasound with bronchoscope fine needle aspiration (EUS-B-FNA) is a valuable tool for the diagnosis and staging of lung cancer, complementing endobronchial lung ultrasound (EBUS). While generally considered safe, there is a notable lack of comprehensive knowledge within the interventional pulmonology community regarding potential complications.

The abundance and sequence of satellite DNA at and around centromeres is evolving rapidly despite the highly conserved and essential process through which the centromere directs chromosome inheritance. The impact of such rapid evolution is unclear. Here we find that sequence-dependent DNA shape dictates packaging of pericentromeric satellites in female meiosis through a conserved DNA-shape-recognizing chromatin architectural protein, high mobility group AT-hook 1 (HMGA1).

Objectives: We hypothesized that semiquantitative visual scoring of lung MRI is suitable for GOLD-grade specific characterization of parenchymal and airway disease in COPD and that MRI scores correlate with quantitative CT (QCT) and pulmonary function test (PFT) parameters.
Methods: Five hundred ninety-eight subjects from the COSYCONET study (median age = 67 (60-72)) at risk for COPD or with GOLD1-4 underwent PFT, same-day paired inspiratory/expiratory CT, and structural and contrast-enhanced MRI. QCT assessed total lung volume (TLV), emphysema, and air trapping by parametric response mapping (PRM, PRM) and airway disease by wall percentage (WP).
