RESUMEN
OBJECTIVES: This study aimed to assess the processes and clinical outcomes of a joint collaboration between Antimicrobial Stewardship Program (ASP) and the outpatient parenteral antimicrobial therapy (OPAT) unit for delivery of monoclonal antibody therapy for mild-to-moderate COVID-19. METHODS: We carried out a retrospective, interim analysis of our COVID-19 monoclonal antibody therapy program. Outcomes included clinical response, incidence of hospitalization, and adverse events. RESULTS: A total of 175 patients (casirivimab-imdevimab, n = 130; bamlanivimab, n = 45) were treated between December 2020 and March 1, 2021. The median time from symptom onset was 6 (IQR 4, 8) days at time of treatment. Of 135 patients available for follow-up, 71.9% and 85.9% of patients reported symptom improvement within 3 and 7 days of treatment, respectively. A total of 9 (6.7%) patients required COVID-19-related hospitalization for progression of symptoms, all within 14 days of treatment. A total of 7 (4%) patients experienced an infusion-related reaction. CONCLUSIONS: ASP-OPAT collaboration is a novel approach to implement an efficient and safe monoclonal antibody therapy program for the treatment of mild-to-moderate COVID-19.

Tessellations of kekulenes and cycloarenes are of considerable interest as nanomolecular belts in trapping and transportation of heavy metal ions and chloride ions, as they possess optimal electronic features and pore sizes. A class of cycloarenes called kekulenes have been the focus of several experimental and theoretical studies from the stand point of aromaticity, superaromaticity, chirality, and novel electrical and magnetic properties. In the present study, we investigate the entropies and topological characterization of different tessellations of kekulenes through topological computations of superaromatic structures with pores. We introduce the self-powered vertex degree-based topological indices and then derive the graph entropy measures for three different tessellations (zigzag, armchair, and rectangular) via various molecular descriptors that we derive here. Several applications to computing the molecular properties are pointed out. We demonstrate the existence of isentropic and yet nonisomorphic tessellations of kekulenes for the first time. The two tessellations are predicted to be quite close in energy with comparable energy gaps. Graph theory-based PPP methods with parameters derived from higher levels of theory are proposed to be promising tools for the predictions of relative stabilities of kekulene tessellations. We show that the developed techniques can be applied in the general context of artificial intelligence for the machine generation of nuclear magnetic resonance and electron spin resonance spectroscopic patterns as well as in robust computations of thermochemistry of a large combinatorial libraries of tessellations of kekulenes through the generation of bond-equivalence classes.
