ATS Core Curriculum 2020. Adult Sleep Medicine.

The American Thoracic Society Core Curriculum updates clinicians annually in adult and pediatric pulmonary disease, medical critical care, and sleep medicine, in a 3-4-year recurring cycle of topics. These topics will be presented at the 2020 Virtual Conference. Below is the adult sleep medicine core that includes topics pertinent to sleep-disordered breathing and insomnia.

Impact of Chronic Obstructive Pulmonary Disease and Emphysema on Outcomes of Hospitalized Patients with Coronavirus Disease 2019 Pneumonia.

Background: Comorbid disease is a risk factor for severe coronavirus disease 2019 (COVID-19) infection. However, initial rates of chronic obstructive pulmonary disease (COPD) in case series were low and severity of COVID-19 in COPD patients was variable.

Methods: We performed a retrospective study of patients admitted with COVID-19 and evaluated outcomes in those with and without COPD and/or emphysema.

Interstitial Emphysema as a Rare Radiographic Presentation of Bronchial Dehiscence after Lung Transplant.

Airway complications after lung transplantation are a major cause of morbidity and mortality. Bronchial dehiscence presents within a month of lung transplantation and is typically diagnosed radiographically as a sentinel gas pocket at the anastomotic site and confirmed with bronchoscopy. A 66-year-old man with idiopathic pulmonary fibrosis who underwent a right lung transplantation 4 weeks prior developed chest pain with palpable crepitus over his right chest wall.

Inferior Vena Cava Filters: Past, Present, and Future.

Inferior vena cava (IVC) filters have existed as a treatment option for VTE for decades. Advances in medical technology have provided physicians with several options for devices that can be placed on either a permanent or temporary basis; however, there are limited data from randomized, controlled trials on the appropriate use of IVC filters. This contemporary review summarizes the history of IVC filters and the types that are available in clinical practice.

Acute Hypoxemic Respiratory Failure and Native Lung Idiopathic Pulmonary Fibrosis Exacerbation in Single-lung Transplant Patients with Cytomegalovirus Disease: A Case Series.

Background: Our case series describes three patients who have received single-lung transplantations for idiopathic pulmonary fibrosis (IPF) that develop cytomegalovirus (CMV) disease and hypoxemic respiratory failure with radiographic opacification of the native lung and sparing of the allograft.

Results: Hypoxemia resolved with treatment and with resolution of CMV viremia. Viral infections causing IPF exacerbations have been described in the literature, however, pulmonary CMV disease in single-lung transplant recipients has typically been observed as pneumonitis of the allograft.
