There is limited information describing the characteristics and clinical outcomes of patients infected with coronavirus disease 2019 (COVID‐19) especially those in underserved urban area with minority population in the United States. This is a retrospective single‐center study for patients who were admitted with COVID‐19 infection. Data collection was from 1 March through 24 April 2020. Demographic, clinical, laboratory, and treatment data were presented using descriptive statistics and frequencies. The χ² test and multivariate logistic regression were used to determine association of risk factors and clinical outcomes. A total of 242 inpatients were included with a mean age of 66 ± 14.75 (±standard deviation). A total of 50% were female and 70% were African American. Comorbidities included hypertension (74%), diabetes mellitus (49%), and 19% had either COPD or asthma. Older age was associated with higher risk of inpatient death odds ratio (OR): 1.056 (95% confidence interval [CI]: 1.023‐1.090; P = .001). Inpatient mortality occurred in 70% who needed mechanical ventilation (OR: 29.51; 95% CI: 13.28‐65.60; P < .0001), 58% who required continuous renal replacement therapy/hemodialysis (CRRT/HD) (OR: 6.63; 95% CI: 2.74‐16.05; P < .0001), and 69% who needed vasopressors (OR: 30.64; 95% CI: 13.56‐69.20; P < .0001). Amongst biomarkers of disease severity, only baseline CRP levels (145 ± 116 mg/L) were associated with mortality OR: 1.008 (95% CI: 1.003‐1.012; P = .002). Majority of hospitalized patients had hypertension and diabetes. Older age was an independent risk factor for inpatient mortality. Requirement of mechanical ventilation, vasopressor use, and CRRT/HD was associated significantly with inpatient mortality. Higher baseline CRP was significantly associated with inpatient death.

Introduction: Bronchoscopic sampling of pulmonary lesions suspicious for lung cancer is frequently non-diagnostic. A genomic sequencing classifier utilizing bronchial brushings obtained at the time of the bronchoscopy has been shown to provide an accurate reclassification of the risk of malignancy (ROM) based on pre-procedure risk. Our objectives for this study were to determine the frequency with which the classifier up-or down-classifies risk in regular clinical practice and to model the potential clinical utility of that reclassification. Methods: This observational study retrospectively assessed data from four clinical sites that regularly use the genomic classifier in the bronchoscopic evaluation of indeterminate lesions. Demographics and pre-bronchoscopy ROM were recorded. The frequency of up- and down-classification was calculated. Modeling based on reclassification rates and the performance characteristics of the classifier was performed to demonstrate the potential clinical utility of the result. Results: 86 patients who underwent classifier testing following a nondiagnostic bronchoscopy were included. 45% of patients with high ROM prior to bronchoscopy were reclassified very high-risk. 38% of patients with intermediate ROM were up-or down-classified. 56% of patients with low ROM were reclassified to very low-risk. Overall, 42% of patients had a change in classification. 35% of the study cohort could potentially have avoided additional unnecessary procedures with subsequent guideline-adherent management. Conclusions: The classifier can guide decision-making following a nondiagnostic bronchoscopy, reclassifying risk in a significant percentage of cases. Use of the classifier should allow more patients with early-stage cancer to proceed directly to curative therapy while helping more patients with benign disease avoid further unnecessary procedures.

Background/Objectives: Combined pulmonary fibrosis and emphysema (CPFE) is associated with poor outcomes. We investigated the association of antifibrotic therapy on patients with CPFE. Methods: This retrospective study included adult patients, older than 18 years, with a diagnosis of CPFE between 2015 and 2019 using TrinetX database. CPFE was defined as a diagnosis of pulmonary fibrosis (PF) and emphysema or chronic obstructive pulmonary disease. Propensity score matching was performed to compare baseline characteristics for CPFE patients on antifibrotic therapy (nintendanib and pirfenidone) with those not on antifibrotic therapy. The outcomes studied included all-cause mortality, major adverse cardiac event (MACE, [myocardial infarction, unstable angina]), hypoxic and hypercapnic respiratory failure, and stroke. These outcomes were compared at one-, three-, and five-year follow-ups. Results: Patients were divided into two cohorts: those on antifibrotic therapy (cohort 1, n = 861) and those without antifibrotic therapy (cohort 2, n = 861). Although not statistically significant, there was a trend towards increased mortality in cohort 1 at the 5-year follow-up (HR 1.14; CI 0.99–1.33). There was also an increased incidence of MI (HR 1.68; CI 0.88–1.47) and hypoxic respiratory failure (HR 1.17; CI 0.99–1.39). Notably, there was also a trend towards decreased incidence of stroke (HR 0.73; CI 0.51–1.05), and no difference in unstable angina (HR 0.94; CI 0.47–1.86) and hypercapnic respiratory failure (HR 0.99; CI 0.67–1.47). Conclusions: For patients with CFPE, antifibrotic use demonstrated a trend towards increased risk of mortality at 5-year follow-up, raising concerns for “sicker patient” bias. Prospective studies should be designed to include patients with CPFE and evaluate the benefits of antifibrotics.
