Abstract
OBJECTIVES Patients with multisystem inflammatory disease in children (MIS-C) are at risk of developing shock. Our objectives were to determine independent predictors associated with development of delayed shock (≥3 hours from emergency department [ED] arrival) in patients with MIS-C and to derive a model predicting those at low risk for delayed shock. METHODS We conducted a retrospective cross-sectional study of 22 pediatric EDs in the New York City tri-state area. We included patients meeting World Health Organization criteria for MIS-C and presented April 1 to June 30, 2020. Our main outcomes were to determine the association between clinical and laboratory factors to the development of delayed shock and to derive a laboratory-based prediction model based on identified independent predictors. RESULTS Of 248 children with MIS-C, 87 (35%) had shock and 58 (66%) had delayed shock. A C-reactive protein (CRP) level greater than 20 mg/dL (adjusted odds ratio [aOR], 5.3; 95% confidence interval [CI], 2.4-12.1), lymphocyte percent less than 11% (aOR, 3.8; 95% CI, 1.7-8.6), and platelet count less than 220,000/uL (aOR, 4.2; 95% CI, 1.8-9.8) were independently associated with delayed shock. A prediction model including a CRP level less than 6 mg/dL, lymphocyte percent more than 20%, and platelet count more than 260,000/uL, categorized patients with MIS-C at low risk of developing delayed shock (sensitivity 93% [95% CI, 66-100], specificity 38% [95% CI, 22-55]). CONCLUSIONS Serum CRP, lymphocyte percent, and platelet count differentiated children at higher and lower risk for developing delayed shock. Use of these data can stratify the risk of progression to shock in patients with MIS-C, providing situational awareness and helping guide their level of care.

Abstract
The process of somatic cell reprogramming is gaining increasing interest as reprogrammed cells are considered to hold a great therapeutic potential. However, with current technologies this process is relatively inefficient. Recent studies reported that inhibition of the p53 tumor suppressor profoundly facilitates reprogramming and attributed this effect to the ability of p53 to restrict proliferation and induce apoptosis. Given that mesenchymal-to-epithelial transition (MET) was recently shown to be necessary for reprogramming of fibroblasts, we investigated whether p53 counteracts reprogramming by affecting MET. We found that p53 restricts MET during the early phases of reprogramming and that this effect is primarily mediated by the ability of p53 to inhibit Klf4-dependent activation of epithelial genes. Moreover, transcriptome analysis revealed a large transcriptional signature enriched with epithelial genes, which is markedly induced by Klf4 exclusively in p53(-/-) cells. We also found that the expression of the epithelial marker E-Cadherin negatively correlates with p53 activity in a variety of mesenchymal cells even before the expression of reprogramming factors. Finally, we demonstrate that the inhibitory effect of p53 on MET is mediated by p21. We conclude that inhibition of the p53-p21 axis predisposes mesenchymal cells to the acquisition of epithelial characteristics and renders them more prone to reprogramming. Our study uncovers a novel mechanism by which p53 restrains reprogramming and highlights the role of p53 in regulating cell plasticity.

Abstract
The purpose of this project was to develop and establish a self-medication program on the rehabilitation ward at Mount Sinai Hospital. Upon discharge most of the patients on this ward are responsible for the self-administration of medications, some of which they will be taking chronically. The objective of this program is to teach patients about their medications while still under medical supervision. Patients are counselled throughout the program by nurses and a pharmacist. Family members are also counselled on request. The program is completed by a final discussion with the patient prior to discharge. As a result of the program a manual was produced for use by pharmacy and nursing personnel to help define their respective roles in the program. Results of a patient survey indicated that a definite benefit was perceived by all patients who were helped to develop their ability to self-medicate. Errors made while in the hospital were discovered and corrected prior to discharge. Pharmacy time required to set up the program was, initially, extensive. Once the program was established, however, nursing medication administration time was greatly decreased and freed for other activities on the floor.
