The Discover In-Hospital Cardiac Arrest (Discover IHCA) Study: An Investigation of Hospital Practices After In-Hospital Cardiac Arrest.

Importance: In-hospital cardiac arrest (IHCA) is a significant public health burden. Rates of return of spontaneous circulation (ROSC) have been improving, but the best way to care for patients after the initial resuscitation remains poorly understood, and improvements in survival to discharge are stagnant. Existing North American cardiac arrest databases lack comprehensive data on the post-resuscitation period, and we do not know current post-IHCA practice patterns.

Observational study of the effect of ketamine infusions on sedation depth, inflammation, and clinical outcomes in mechanically ventilated patients with SARS-CoV-2.

Severely ill patients with COVID-19 are challenging to sedate and often require high-dose sedation and analgesic regimens. Ketamine can be an effective adjunct to facilitate sedation of critically ill patients but its effects on sedation level and inflammation in COVID-19 patients have not been studied. This retrospective, observational cohort study evaluated the effect of ketamine infusions on inflammatory biomarkers and clinical outcomes in mechanically ventilated patients with SARS-CoV-2 infection.

Design and rationale of the CHILL phase II trial of hypothermia and neuromuscular blockade for acute respiratory distress syndrome.

The Cooling to Help Injured Lungs (CHILL) trial is an open label, two group, parallel design multicenter, randomized phase IIB clinical trial assessing the efficacy and safety of targeted temperature management with combined external cooling and neuromuscular blockade to block shivering in patients with early moderate-severe acute respiratory distress syndrome (ARDS). This report provides the background and rationale for the clinical trial and outlines the methods using the Consolidated Standards of Reporting Trials guidelines. Key design challenges include: [1] protocolizing important co-interventions; [2] incorporation of patients with COVID-19 as the cause of ARDS; [3] inability to blind the investigators; and [4] ability to obtain timely informed consent from patients or legally authorized representatives early in the disease process.

Systemic Inflammatory Response Syndrome After Extracorporeal Membrane Oxygenation Decannulation in COVID-19 Patients.

Introduction: Systemic inflammatory response syndrome (SIRS) is frequently observed following decannulation from extracorporeal membrane oxygenation (ECMO). Differentiating cytokine release due to infection from endothelial injury from cannula removal and/or discontinuation from the ECMO circuit has been shown to impact treatment and outcomes. This response, however, may be complicated in COVID-19 patients due to prevalent glucocorticoid and immune modulator use.

Design: Retrospective observational study.

Setting: Multicenter, international COVID-19 registry.

Characteristics of Post-ICU and Post-COVID Recovery Clinics in 29 U.S. Health Systems.

Unlabelled: The multifaceted long-term impairments resulting from critical illness and COVID-19 require interdisciplinary management approaches in the recovery phase of illness. Operational insights into the structure and process of recovery clinics (RCs) from heterogeneous health systems are needed. This study describes the structure and process characteristics of existing and newly implemented ICU-RCs and COVID-RCs in a subset of large health systems in the United States.

A multidisciplinary approach to prolonged extracorporeal membrane oxygenation for acute respiratory distress syndrome due to coronavirus 2019-case report.

Patients with novel coronavirus 2019 (COVID-19) may develop acute respiratory distress syndrome (ARDS) and require extracorporeal membrane oxygenation (ECMO) support. Currently there is no specific treatment for COVID-19 available; thus, for patients with severe ARDS, the respiratory condition needs to improve while on ECMO support. Here we present a multidisciplinary team approach to the care of a patient with COVID-related ARDS requiring three months of veno-venous (VV) ECMO which lead to recovery.

Outcomes of extracorporeal membrane oxygenation in influenza versus COVID-19 during the first wave of COVID-19.

Purpose: Extracorporeal membrane oxygenation (ECMO) is a refractory treatment for acute respiratory distress syndrome (ARDS) due to influenza and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, also referred to as coronavirus disease 2019 [COVID-19]). We conducted this study to compare the outcomes of influenza patients treated with veno-venous-ECMO (VV-ECMO) to COVID-19 patients treated with VV-ECMO, during the first wave of COVID-19.

Methods: Patients in our institution with ARDS due to COVID-19 or influenza who were placed on ECMO between August 1, 2010 and September 15, 2020 were included in this comparative, retrospective study.

COVID-19 treatment combinations and associations with mortality in a large multi-site healthcare system.

Introduction: During the early months of the COVID-19 pandemic, mortality associated with the disease declined in the United States. The standard of care for pharmacological interventions evolved during this period as new and repurposed treatments were used alone and in combination. Though these medications have been studied individually, data are limited regarding the relative impact of different medication combinations.

Development and Validation of a Web-Based Severe COVID-19 Risk Prediction Model.

Background: Coronavirus disease 2019 (COVID-19) carries high morbidity and mortality globally. Identification of patients at risk for clinical deterioration upon presentation would aid in triaging, prognostication, and allocation of resources and experimental treatments.

Research Question: Can we develop and validate a web-based risk prediction model for identification of patients who may develop severe COVID-19, defined as intensive care unit (ICU) admission, mechanical ventilation, and/or death?

Methods: This retrospective cohort study reviewed 415 patients admitted to a large urban academic medical center and community hospitals.

Outcomes of extracorporeal membrane oxygenation in acute respiratory distress syndrome due to COVID-19: The lessons learned from the first wave of COVID-19.

Introduction: Extracorporeal membrane oxygenation (ECMO) has been used as a refractory treatment for acute respiratory distress syndrome (ARDS) due to coronavirus disease 2019 (COVID-19), but there has been little evidence of its efficacy. We conducted this study to share our experience using ECMO as a bridge to recovery for ARDS due to COVID-19.

Methods: All adult patients who were placed on ECMO for ARDS due to COVID-19 between April 2020 and June 2020 (during the first wave of COVID-19) were identified.

Tocilizumab in the Management of COVID-19: A Preliminary Report.

Importance: Pneumonia due to COVID-19 can lead to respiratory failure and death due to the development of the acute respiratory distress syndrome. Tocilizumab, a monoclonal antibody targeting the interleukin-6 receptor, is being administered off-label to some patients with COVID-19, and although early small studies suggested a benefit, there are no conclusive data proving its usefulness.

Objective: To evaluate outcomes in hospitalized patients with COVID-19 with or without treatment with Tocilizumab.

Utilization of extracorporeal life support for diffuse alveolar damage and diffuse alveolar hemorrhage: A systematic review.

Modern extracorporeal life-support (ECLS) technology has been successfully utilized to treat patients with diffuse alveolar damage (DAD) and diffuse alveolar hemorrhage (DAH); however, reports in the literature remain scarce. We sought to pool existing evidence to better characterize ECLS use in these patients. An electronic search was conducted to identify all studies in the English literature reporting the use of ECLS for DAD/DAH.

Clinical presentations and outcomes in pulmonary embolism patients with cancer.

To study whether a diagnosis of cancer affects the clinical presentation and outcomes of patients with pulmonary embolism (PE). A retrospective analysis was performed of all consecutive patients diagnosed with PE on a computed tomography scan from 2014 to 2016 at an urban tertiary-referral medical center. Baseline characteristics, treatment decisions, and mortality data were compared between study subjects with and without a known diagnosis of active cancer.

The original version of this article unfortunately contained a mistake. The spelling of the Hitoshi Hirose name was incorrect. It was corrected in this erratum.

Don't Drive Blind: Driving Pressure to Optimize Ventilator Management in ECMO.

Introduction: Driving pressure (DP) while on ECMO has been studied in acute respiratory distress syndrome (ARDS) but no studies exist in those on ECMO without ARDS. We aimed to study association of mortality with DP in all patients on ECMO and compare change in DP before and after initiation of ECMO.

Methods: Consecutive patients placed on ECMO either veno-arterial ECMO or veno-venous ECMO between August 2010 and February 2017 were reviewed.

Pulmonary Embolism in Intensive Care Unit.

Management of pulmonary embolism (PE) has become more complex due to the expanded role of catheter-based therapies, surgical thrombectomies, and cardiac assist technologies, such as right ventricular assist devices and extracorporeal support. Due to the heterogeneity of PE, a multidisciplinary team approach is necessary. The manifestation of PE response teams are in response to this complex need and similar to the proliferation of stroke, trauma, and rapid response teams.

Inhibitory Activity of Insulin on Aβ Aggregation Is Restricted Due to Binding Selectivity and Specificity to Polymorphic Aβ States.

Clinical trials of intranasal insulin treatment for Alzheimer's patients have shown cognitive and memory improvement, but the effect of insulin has shown a limitation. It was suggested that insulin molecule binds to Aβ aggregates and impedes Aβ aggregation. Yet, the specific interactions between insulin molecule and Aβ aggregates at atomic resolution are still elusive.

Point-of-care versus central testing of hemoglobin during large volume blood transfusion.

Background: Point-of-care (POC) hemoglobin testing has the potential to revolutionize massive transfusion strategies. No prior studies have compared POC and central laboratory testing of hemoglobin in patients undergoing massive transfusions.

Methods: We retrospectively compared the results of our point-of-care hemoglobin test (EPOC®) to our core laboratory complete blood count (CBC) hemoglobin test (Sysmex XE-5000™) in patients undergoing massive transfusion protocols (MTP) for hemorrhage.
