You will be shown an abstract from a biomedical research paper. Given this abstract, your task is to extract all unique entities of the following types: ["HealthCareActivity", "InjuryOrPoisoning", "BodySubstance", "IntellectualProduct", "AnatomicalStructure", "SpatialConcept", "Chemical", "Bacterium", "MedicalDevice", "Organization", "BiomedicalOccupationOrDiscipline", "Finding", "BiologicFunction", "Virus", "ResearchActivity", "ClinicalAttribute", "PopulationGroup", "Eukaryote", "BodySystem", "Food", "ProfessionalOrOccupationalGroup"].

Please return the output as a JSON object of the format: {"Virus": ["HIV", ...], "Bacterium": ["MRSA", ...], "AnatomicalStructure": ["Lung", ...], "BodySystem": ["CNS", ...], "BodySubstance": ["Serum", ...], "Finding": ["Headache", ...], "InjuryOrPoisoning": ["Fracture", ...], "BiologicFunction": ["Death", ...], "HealthCareActivity": ["Biopsy", ...], "ResearchActivity": ["Clinical trial", ...], "MedicalDevice": ["Lenses", ...], "SpatialConcept": ["Camps", ...], "BiomedicalOccupationOrDiscipline": ["Forensic medicine", ...], "Organization": ["WHO", ...], "ProfessionalOrOccupationalGroup": ["Provider", ...], "PopulationGroup": ["Swimmers", ...], "Chemical": ["Gold", ...], "Food": ["Rice", ...], "IntellectualProduct": ["RPAM", ...], "ClinicalAttribute": ["Biomarker", ...], "Eukaryote": ["Dogs", ...]}. The keys should be entity types and values should be lists of extracted entities belonging to the corresponding type. If you cannot find entities belonging to a specific type, the value should be [].

Only output the JSON object and do not include any additional text.

Abstract:

Diagnostic utility of additional conventional techniques after endobronchial ultrasonography guidance during transbronchial biopsy Endobronchial ultrasonography with a guide sheath transbronchial biopsy (EBUS - GS TBB) has been used to diagnose peripheral pulmonary lesions (PPLs). In this study, we evaluated the diagnostic utility of conventional TBB after EBUS - GS TBB. A retrospective analysis of patients who underwent conventional TBB after EBUS - GS TBB for PPL between August 1, 2012 and December 31, 2014. We performed multivariate analysis to examine the association of various clinical factors, including EBUS probe distance and sample size area, with diagnostic yield. Of 88 eligible patients, 57 (65%) were successfully diagnosed by EBUS - GS TBB. In 31 patients not diagnosed by EBUS - GS TBB, 15 (48%) were successfully diagnosed by additional conventional TBB. Ground glass opacity (GGO) was a significant factor associated with the diagnostic yield of additional conventional TBB following EBUS - GS TBB. Multivariate analysis and receiver operator curves revealed that distance between the PPL and the EBUS probe of less than 2.55 mm favored the utility of conventional TBB. Additional conventional TBB after EBUS - GS TBB could be a useful procedure for the diagnosis of ground glass opacity PPLs and in cases of a distance of less than 2.55 mm between the EBUS probe and the lesion.
