Introduction: Cellular characteristics of induced sputum (IS) are not investigated in cystic fibrosis (CF) patients.
Objectives: This pilot study, conducted on 17 expectorating CF adolescents, compared sputa obtained the same day, in a stable period, by autogenic drainage (expectorating sputum, ES) and 4 h later after inhaling hypertonic saline (IS).
Results: No difference was noted concerning weight, volume, and percentage of dead cells between the two collection methods.

Introduction: Segmental anatomical resections have been a subject of debate in recent years. There is increasing evidence that these procedures may offer some advantages in the treatment of early-stage lung cancer, with overall survival (OS) and disease-free survival (DFS) similar to those seen in lobar anatomical resections.
Materials And Methods: We conducted a retrospective analysis of patients who underwent segmentectomy at Santa Marta Hospital (HSM) between January 2018 and September 2022.
