The Minnesota Critical Care Working Group 1: Monitoring and coordinating statewide critical care surge response in the COVID-19 pandemic, March 2020 through July 1, 2021.

Background: In response to the COVID-19 pandemic and as part of the statewide healthcare coalition response the Minnesota Critical Care Working Group (CCWG), composed of Interprofessional leaders from the state's nine largest health systems was established and entrusted to plan and coordinate critical care support for Minnesota from March 2020 through July1, 2021.

Research Question: Can a statewide Critical Care Working Group develop contingency and crisis level surge strategies and indicators in response to the COVID-19 pandemic while evolving into a highly collaborative team?

Study Design And Methods: CCWG members (Intensivists, ethicists, nurses, MDH and MHA leaders) met by audio video conferencing as often as daily assessing COVID and non-COVID hospitalization data, developed surge indicators reflecting contingency versus crisis conditions, and planned responses collaboratively. A foundation of collaboration and teamwork developed which facilitated an effective statewide response.

Synthesis and biological characterization of a 17β hydroxysteroid dehydrogenase type 10 (17β-HSD10) inhibitor.

Alzheimer's disease (AD) is estimated to affect over 55 million people across the world. Small molecule treatment options are limited to symptom management with no impact on disease progression. The need for new protein targets and small molecule hit compounds is unmet and urgent.

The Minnesota Critical Care Working Group 2: Crisis conditions during the COVID-19 Pandemic, July 2021 through March 2022.

Background: At the request of the Statewide Healthcare Coordination Center, the Minnesota Critical Care Working Group (CCWG) and ethics subgroup (EWG), composed of interprofessional leaders from Minnesota's nine largest health systems were asked to plan and coordinate critical care operations during the COVID-19 pandemic, including the 2021 Fall surge.

Research Question: Can a statewide Working Group collaboratively analyze real time evidence to identify crisis conditions and engage state leadership to implement care processes?

Study Design And Methods: CCWG/EWG met via video conferencing during the Fall 2021 severe surge to analyze evidence and plan for potential crisis care conditions. Five sources of evidence informed their actions including group consensus on operating conditions; Federal Tele-Tracking data; MOCC patient placement data; and two surveys created and distributed to hospitals and healthcare professionals.

Cancer stem cells release interleukin-33 within large oncosomes to promote immunosuppressive differentiation of macrophage precursors.

In squamous cell carcinoma (SCC), macrophages responding to interleukin (IL)-33 create a TGF-β-rich stromal niche that maintains cancer stem cells (CSCs), which evade chemotherapy-induced apoptosis in part via activation of the NRF2 antioxidant program. Here, we examined how IL-33 derived from CSCs facilitates the development of an immunosuppressive microenvironment. CSCs with high NRF2 activity redistributed nuclear IL-33 to the cytoplasm and released IL-33 as cargo of large oncosomes (LOs).

Cell-free DNA methylation analysis as a marker of malignancy in pleural fluid.

Diagnosis of malignant pleural effusion (MPE) is made by cytological examination of pleural fluid or histological examination of pleural tissue from biopsy. Unfortunately, detection of malignancy using cytology has an overall sensitivity of 50%, and is dependent upon tumor load, volume of fluid assessed, and cytopathologist experience. The diagnostic yield of pleural fluid cytology is also compromised by low abundance of tumor cells or when morphology is obscured by inflammation or reactive mesothelial cells.
