Trends in mortality with chronic obstructive pulmonary disease as the underlying cause and chronic kidney disease as a contributing cause among US adults, 1999-2020: a CDC WONDER analysis.

Study Takeaway
The age-adjusted mortality rate more than doubled from 0.79 in 1999 to 1.96 per 100,000 population in 2020, with an overall average annual percent change of + 4.71% (95% CI: 3.06-6.38), highlighting an urgent need for integrated pulmonary-renal care in clinical practice.

Cryobiopsy Reveals the Architectural Maturity of Tertiary Lymphoid Structures in Lung Cancer.

Study Takeaway
For interventional pulmonologists, this demonstrates that transbronchial cryobiopsy preserves delicate tumor immune microarchitecture without crush artifacts, overcoming traditional forceps biopsy limitations and enabling the assessment of tertiary lymphoid structure maturity for pretreatment immunotherapy profiling.

The efficacy-invasiveness trade-off: a retrospective cohort comparison of surgical operation and endobronchial valves for refractory lung bullae disease.

Study Takeaway
While endobronchial valves offered a safer, less invasive perioperative profile, surgical operation provided superior long-term recurrence-free survival (2-year rate: 86.5% vs. 70.0%; HR for EBV: 2.48, P < 0.001), particularly in patients with giant bullae of ≥ 10 cm.

Bronchoscopic evaluation of human airway surface liquid pH.

Study Takeaway
This study investigated airway surface liquid (ASL) pH and its regulating genes in healthy individuals and asthma patients to support the development of therapies that treat airway diseases by modifying lung acidity.

Combined indwelling pleural catheter with thoracoscopic talc poudrage for malignant pleural effusion management: a randomized non-inferiority trial.

Study Takeaway
Combining the procedures demonstrated non-inferior 12-week pleurodesis success (89.5% versus 68.4%) while significantly reducing median hospital length of stay (1 versus 4 days, P < 0.001) and improving dyspnea scores.
BMC pulmonary medicine

A study of excessive dynamic airway collapse in chronic obstructive pulmonary disease patients.

Study Takeaway
Excessive dynamic airway collapse affects a significant portion of symptomatic chronic obstructive pulmonary disease patients and is independently predicted by body mass index, modified Medical Research Council, and COPD Assessment Test scores, with dynamic chest computed tomography achieving 93.1% sensitivity (95% CI 77.2-99.2) and 100% specificity (95% CI 92.3-100.0) for diagnosis.

Diagnostic value of biochemical ratios in the differential diagnosis of tuberculous and malignant pleural effusions.

Study Takeaway
For interventional pulmonologists, the serum LDH to ADA ratio emerged as a powerful discriminatory marker with an AUC of 0.938, sensitivity of 89.5%, and specificity of 91.3%, offering a reliable, minimally invasive way to guide clinical decisions when invasive procedures are limited.
Chest

A Comparative Study of Radiation Exposure in Conventional and Robotic Bronchoscopy.

Study Takeaway
Robotic bronchoscopy using C-arm-based tomosynthesis significantly increased median total radiation exposure per case to 0.237 mSv compared to conventional and standard fluoroscopy robotic methods (P = 0.025), meaning clinicians must carefully monitor imaging use to align with safety recommendations.

The complementary roles of endobronchial ultrasound-guided needle aspiration, mini-forceps, and cryobiopsy in the investigation of mediastinal lesions.

Study Takeaway
While overall diagnostic yield was similar across modalities, TBCB provided significantly higher-quality tissue for molecular profiling assays (P = 0.002) and less crush artifact compared to TBFB (P < 0.0001). Clinicians should consider supplementing EBUS-TBNA with TBFB or TBCB when suspecting inflammatory or lymphoproliferative conditions, or when high-quality tissue is needed for molecular assays.
