With the continued transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) throughout the world, identification of highly suspected COVID-19 patients remains an urgent priority. In this study, we developed and validated COVID-19 risk scores to identify patients with COVID-19. In this study, for patient-wise analysis, three signatures, including the risk score using radiomic features only, the risk score using clinical factors only, and the risk score combining radiomic features and clinical variables, show an excellent performance in differentiating COVID-19 from other viral-induced pneumonias in the validation set. For lesion-wise analysis, the risk score using three radiomic features only also …

A Lung Cancer Screening Personalized Decision-Aid Improves Knowledge And Reduces Decisional Conflict Among A Diverse Population Of Smokers At An Urban Academic Medical Center, Madeline Kaufman, Nilan Schnure, Andrea Nicholson, Frank Leone, Carmen Guerra

Journal of Health Disparities Research and Practice

Introduction: Few lung cancer screening decision aids have been tested in diverse populations. The study objective was to determine whether the online decision aid www.shouldiscreen.com impacts knowledge of and decisional conflict around lung cancer screening in a diverse population.

Methods: Eligible patients had significant smoking histories, were at increased risk for lung cancer (ages 45-80, >20 pack-years, smoking within last 15 years) and had no history of prior lung cancer or screening. Data was collected and analyzed in 2017.

Results: 40 patients were enrolled: 80% were female, 62.5% black, 33% white, and 48% had a high school …

Exogenous Lipoid Pneumonia Complicated By Mineral Oil Asperation In A Patient With Chronic Constipation: A Case Report And Review, Hafiz Muhammad Jeelani, Muhammad Mubbashir Sheikh, Belaal Sheikh, Hafiz Mahboob, Anchit Bharat

School of Medicine Faculty Research

Exogenous lipoid pneumonia is a rare and frequently misdiagnosed lung disease. It occurs as an inflammatory reaction secondary to either aspiration or inhalation of lipids. Our patient had a history significant for recurrent pneumonia and the use of mineral oil for chronic constipation. A chest computed tomography showed multifocal consolidative opacities with areas of low attenuation, highly suspicious of exogenous lipid pneumonia. The diagnosis was confirmed with combined bronchoalveolar lavage and transbronchial lung biopsy that showed lipid-laden macrophages consistent with exogenous lipoid pneumonia. After thorough medication review, apart from mineral oil, no other contributing factors were found. A diagnosis of …

Recent Advances In Understanding And Management Of Bronchopulmonary Dysplasia, Vineet Bhandari, Mitali Sahni

School of Medicine Faculty Research

© 2020 Sahni M and Bhandari V. In the current era, the survival of extremely low-birth-weight infants has increased considerably because of new advances in technology; however, these infants often develop chronic dysfunction of the lung, which is called bronchopulmonary dysplasia (BPD). BPD remains an important cause of neonatal mortality and morbidity despite newer and gentler modes of ventilation. BPD results from the exposure of immature lungs to various antenatal and postnatal factors that lead to an impairment in lung development and aberrant growth of lung parenchyma and vasculature. However, we still struggle with a uniform definition for BPD that …

Rethinking Intravenous Catheter Size And Location For Computed Tomography Pulmonary Angiography, Travis Marshall, Nae Meng Chen, Eric Nguyen, David E. Slattery, Tony Zitek

School of Medicine Faculty Research

Introduction: Computed tomography pulmonary angiography (CTPA) is the test of choice for diagnosis of pulmonary embolism (PE) in the emergency department (ED), but this test may be indeterminate for technical reasons such as inadequate contrast filling of the pulmonary arteries. Many hospitals have requirements for intravenous (IV) catheter size or location for CTPAs to reduce the chances of inadequate filling, but there is a lack of clinical data to support these requirements. The objective of this study was to determine if a certain size or location of IV catheter used for contrast for CTPA is associated with an increased chance …
