Our results could be explained by the early adoption of widespread testing and a successful national response to the pandemic.
We report a lower overall ratio of ICU admissions for coronavirus disease 2019 among severe acute respiratory syndrome coronavirus 2 positive patients and a lower hospital mortality for patients treated in the ICU for coronavirus disease 2019 compared with initial reports from Italy and China. Our results could be explained by the early adoption of widespread testing and a successful national response to the pandemic.
To describe the importance of critical care clinical research that is not pandemic-focused during pandemic times; outline principles to assist in the prioritization of nonpandemic research during pandemic times; and propose a guiding framework for decisions about whether, when and how to continue nonpandemic research while still honoring the moral and scientific imperative to launch research that is pandemic-focused.

Using in-person, email, and videoconference exchanges, we convened an interprofessional clinical research group, conducted a literature review of empirical studies, ethics documents and expert commentaries (2010 to present), and viewed traditional and social media posts (March 2020 to May 2020). Stakeholder consultation involved scientific, ethics, clinical, and administrative leaders.

Clinical research in the ICU.

Patients with and without coronavirus disease 2019.

None.

While clinical research should be prioritized to advantage patients with coronavirus disease 2019 in order to care model, protocol complexity, data collection, and implementation integrity. Decisions to pause or pursue nonpandemic research should be proportionate, transparent, and revisited as the pandemic abates.
Deliberation about continuing nonpandemic research should use objective, transparent criteria considering several aspects of the research process such as bedside and research staff safety, infection control, the informed consent model, protocol complexity, data collection, and implementation integrity. Decisions to pause or pursue nonpandemic research should be proportionate, transparent, and revisited as the pandemic abates.
Heart transplantation concomitant with a liver transplant may be warranted when end-stage heart failure results in irreversible liver failure. Previously reported outcomes have been excellent yet the specific immunoprotective role of the liver allograft is not known. We review the current literature about the immunologic benefit for combined heart and liver transplantation (CHLT).

The total number of combined heart and liver transplants continues to increase and accounts for approximately 25 cases per year. Familial amyloid polyneuropathy with cardiac cirrhosis is the most common indication for CHLT while adult congenital heart disease (CHD) with associated cirrhosis is increasing in frequency. The majority of recent registry data suggest a statistically equivalent to modestly improved survival advantage for CHLT compared with isolated heart transplantation. Direct mechanisms accounting for this survival advantage are not proven, but combined heart and liver transplants experience lower rates of acute carvalent to modestly improved survival outcomes, lower rates of acute cardiac rejection and CAV warrant further investigation into the liver allograft's immunoprotective effect on the transplanted heart. The key mechanisms of tolerogenicity have important implications for surgical technique and immunosuppression requirements. Future directions include development of criteria for heart-liver transplant candidacy and identification of equitable allocation protocols.
To describe the most recent progress towards tolerance in xenotransplantation.

Mixed chimerism and thymic transplantation have been used to promote tolerance in xenotransplantation models. Intra-bone bone marrow transplantation is a recent advance for mixed chimerism, which promotes longer lasting chimerism and early graft function of subsequent organ transplantation. The hybrid thymus, an advancement to the vascularized thymokidney and vascularized thymic lobe, is being developed to allow for both donor and recipient T-cell selection in the chimeric thymus, encouraging tolerance to self and donor while maintaining appropriate immune function. Regulatory T cells show promise to promote tolerance by suppressing effector T cells and by supporting mixed chimerism. Monoclonal antibodies such as anti-CD2 may promote tolerance through suppression of CD2+ effector and memory T cells whereas Tregs, which express lower numbers of CD2, are relatively spared and might be used to promote tolerance.

These findings contribute major advances to tolerance in xenotransplantation. piperacillin concentration A combination of many of these mechanisms will likely be needed to have long-term tolerance maintained without the use of immunosuppression.

Opioid use in patients with inflammatory bowel disease (IBD) is associated with increased mortality. Previous interventions targeting reduced intravenous opioid (IVOPI) exposure for all patients admitted to a general medical unit have decreased total opioid use without compromising pain control. We therefore performed a prospective evaluation of a multimodal intervention encouraging the use of nonopioid alternatives to reduce IVOPI exposure among patients with IBD hospitalized at our institution.

This was a prospective evaluation of a multimodal intervention to reduce IVOPI use among patients with IBD aged ≥18 years admitted to a general medical unit at a large urban academic medical center from January 1, 2019, to June 30, 2019. Intravenous and total (all routes) opioid exposures were measured as proportions and intravenous morphine milligram equivalents/patient day and compared with preintervention (January 1, 2018, to December 31, 2018) data. Hospital length of stay (LOS), 30-day readmission rates (RRs), and pain scores (1-10 scale) were also assessed.
