Background During a pandemic, it is important for clinicians to stratify patients and decide who receives limited medical resources. Machine learning models have been proposed accurately predict COVID-19 disease severity. Previous studies typically tested only one machine algorithm performance evaluation area under the curve analysis. To obtain best results possible, may be test different algorithms find prediction model. Objective In this study, we aimed use automated (autoML) train various...

Study Design. This study investigated the use of mechanically elicited electromyograms during placement pedicle screws in 89 patients undergoing surgery for spinal stenosis. Summary Background Data. Several methods monitoring nerve roots are available. However, may be more sensitive to mechanical irritation by than other methods. Methods. Mechanically were recorded muscle groups innervated cervical or lumbar roots. Confirmation surgical activity with level electromyogram was correlated....

BACKGROUND When manufacturing chimeric antigen receptor (CAR) T cells using anti‐CD3/anti‐CD28 beads, ex vivo T‐cell expansion is dependent on the composition of leukocytes used in process. We investigated effects leukocyte CAR and characteristics an alternative method. METHODS Anti–B‐cell maturation CD19‐CAR were manufactured autologous peripheral blood mononuclear cell (PBMNC) concentrates. The PBMNCs enriched for lymphocytes density gradient separation, which culture initiation. was...
