Conducting randomized controlled trials (RCTs) in the context of CS poses significant challenges due to ethical considerations and logistical complexities. In response to these challenges, emulated trials (ETs) are emerging as a promising alternative. By incorporating design features from idealized RCTs, they use robust and rigorous methods to assess the efficacy and safety of health interventions in real-life settings, using observational data. In our manuscript, we highlight the complementary nature of RCT and ETs by evaluating tMCS for CS patients. While RCTs follow a rigorous experimental design and provide reliable evidence, ETs can swiftly estimate the risk-benefit ratio without encountering logistical barriers thereby offering clinicians' early reassurance about the potential benefits of routinely used interventions.

EBB represents an attractive alternative to transbronchial biopsy (TBB): EBB provides straightforward sampling of airway pathology with decreased complication rates due to minimal and visualizable bleeding and the elimination of pneumothorax risk. In lung transplant recipients, EBB may be obtained when TBB is too high-risk, including in the setting of acute lung allograft dysfunction (ALAD) requiring mechanical ventilation or in advanced chronic lung allograft dysfunction (CLAD). Most centers do not include EBB in post-transplant surveillance or for-cause bronchoscopy protocols, possibly due to a lack of a common histologic interpretation system. Previous work has demonstrated that lymphocytic inflammation in lung transplant EBB is associated with acute cellular rejection and future risk for CLAD, but these have not translated into subsequent studies on clinical utility or into clinical practice. Recent multicenter studies suggest that gene expression-based diagnostics leveraging EBB may outperform histologic grading and provide important prognostic utility in predicting graft loss. Herein, we will review what is known about the lung transplant mucosa including recent diagnostic advances and propose how EBB analyses could be incorporated into research studies and clinical workflows.
