Brief summary

This project will study and characterize Microplastic (MP) burden in the lungs of patients undergoing Bronchoalveolar Levage (BAL) in thoracic clinics at Moffitt.

Interventions

PROCEDUREBronchoalveolar Lavage (BAL) during Bronchoscopy

Bronchoalveolar Lavage (BAL) is a standard diagnostic tool for the evaluation of lower respiratory tract pathology including respiratory infections and unexplained radiographic pulmonary lesions including lung neoplasia. It is a minimally invasive procedure that involves introduction of the bronchoscope, installation of sterile normal saline into a subsegment of the lung, and suction and collection of the recovered saline for diagnostic evaluation.

Inclusion criteria

* English or Spanish-speaking patients scheduled for bronchoscopy/bronchoalveolar lavage (BAL) in thoracic clinics at Moffitt.

Exclusion criteria

* Patients with a known prior history of lung cancer or that have undergone a Bronchoalveolar Lavage (BAL) procedure at any time in the past in the involved lung targeted for BAL. * Patients that have had any prior lung or thoracic or surgeries or procedures (examples: removal of lung or portions of the involved lung (lobectomy, pneumonectomy, wedge resection/segmentectomy). * Patients with specimens that are considered to be non-adequate as true Bronchoalveolar Lavage Fluid (BALF) (i.e., absence of alveolar macrophages) after pathologist's evaluation will be excluded from the study.

Design outcomes

Primary

MeasureTime frameDescription
Characterization of Microplastic (MP) Burden in the LungsUp to 24 MonthsMicroplastic (MP) Burden in the Lungs will be determined by the results of the Bronchoscopy/Bronchoalveolar Lavage (BAL). MPs isolated from Bronchoalveolar Fluid (BALF) will be characterized using Raman spectroscopy (RS). RS is a vibrational spectroscopy technique based on the inelastic scattering of light that provides information on the molecular vibrations of a system in the form of a vibrational spectrum. The Raman spectrum is akin to a fingerprint of chemical structure allowing identification of the components present in the sample. For each sample, data will be generated on the presence or absence of MPs, total number of MPs, and polymer subtype distribution of MPs identified in the samples.

Secondary

MeasureTime frameDescription
Concentration of Microplastics (MPs) in Lung Cancer PatientsUp to 24 MonthsConcentration of Microplastics (MPs) will be determined by the number of MPs identified in 10-mLs of Bronchoalveolar Fluid (BALF).
Concentration of Microplastics (MPs) in Non-Lung Cancer PatientsUp to 24 MonthsConcentration of Microplastics (MPs) will be determined by the number of MPs identified in 10-mLs of Bronchoalveolar Fluid (BALF).
