    OBJECTIVE: This study aimed to determine whether obesity is independently associated with major adverse clinical outcomes and inflammatory and thrombotic markers in critically ill patients with COVID-19. METHODS: The primary outcome was in-hospital mortality in adults with COVID-19 admitted to intensive care units across the US. Secondary outcomes were acute respiratory distress syndrome (ARDS), acute kidney injury requiring renal replacement therapy (AKI-RRT), thrombotic events, and seven blood markers of inflammation and thrombosis. Unadjusted and multivariable-adjusted models were used. RESULTS: Among the 4,908 study patients, mean (SD) age was 60.9 (14.7) years, 3,095 (62.8%) were male, and 2,552 (52.0%) had obesity. In multivariable models, BMI was not associated with mortality. Higher BMI beginning at 25 kg/m2 was associated with a greater risk of ARDS and AKI-RRT but not thrombosis. There was no clinically significant association between BMI and inflammatory or thrombotic markers. CONCLUSIONS: In critically ill patients with COVID-19, higher BMI was not associated with death or thrombotic events but was associated with a greater risk of ARDS and AKI-RRT. The lack of an association between BMI and circulating biomarkers calls into question the paradigm that obesity contributes to poor outcomes in critically ill patients with COVID-19 by upregulating systemic inflammatory and prothrombotic pathways.

    Tracheostomy Practices and Outcomes in Children during Respiratory ECMO
    (Wolters Kluwer, 2022-04) Kohne, Joseph G.; MacLaren, Graeme; Rider, Erica; Carr, Benjamin; Mallory, Palen; Gebremariam, Acham; Friedman, Matthew L.; Barbaro, Ryan P.; Pediatrics, School of Medicine
    Objectives: Children receiving prolonged extracorporeal membrane oxygenation (ECMO) support may benefit from tracheostomy during ECMO by facilitating rehabilitation; however the procedure carries risks, especially hemorrhagic complications. Knowledge of tracheostomy practices and outcomes of ECMO-supported children who undergo tracheostomy on ECMO may inform decision-making. Design: Retrospective cohort study Setting: ECMO centers contributing to the Extracorporeal Life Support Organization (ELSO) Registry Patients: Children birth to 18 years who received ECMO support for 7 days or greater for respiratory failure from January 1st 2015 to December 31st 2019. Interventions: None Measurements and Main Results: 3685 children received at least seven days of ECMO support for respiratory failure. The median duration of ECMO support was 13.0 days (IQR 9.3-19.9), and in-hospital mortality was 38.7% (1426/3685). A tracheostomy was placed during ECMO support in 94/3685 (2.6%). Of those who received a tracheostomy on ECMO, the procedure was performed at a median 13.2 days (IQR 6.3-25.9) after initiation of ECMO. Surgical site bleeding was documented in 26% of children who received a tracheostomy (12% after tracheostomy placement). Among children who received a tracheostomy, the median duration of ECMO support was 24.2 days (IQR 13.0-58.7); in-hospital mortality was 30/94 (32%). Those that received a tracheostomy before 14 days on ECMO were older (median age 15.8 years (IQR 4.7-15.5) versus 11.7 years (IQR 11.5-17.3); p-value=0.002) and more likely to have been supported on VV-ECMO (84% vs 52%, p=0.001). Twenty-two percent (11/50) of those who received a tracheostomy before 14 days died in the hospital, compared to 19/44 (43%) of those who received a tracheostomy at 14 days or later (p=0.03). Conclusions: Tracheostomies during ECMO were uncommon in children. One in four patients who received a tracheostomy on ECMO had surgical site bleeding. Children who had tracheostomies placed after 14 days were younger and had worse outcomes, potentially representing tracheostomy as a “secondary” strategy for prolonged ECMO support.
