Abstract

The development of specific antiviral therapies targeting SARS-CoV-2 remains fundamental because of the continued high incidence of COVID-19 and limited accessibility to antivirals in some countries. In this context, dark chemical matter (DCM), a set of drug-like compounds with outstanding selectivity profiles that have never shown bioactivity despite being extensively assayed, appears to be an excellent starting point for drug development. Accordingly, in this study, we performed a high-throughput screening to identify inhibitors of the SARS-CoV-2 main protease (Mpro) using DCM compounds as ligands. Multiple receptors and two different docking scoring functions were employed to identify the best molecular docking poses. The selected structures were subjected to extensive conventional and Gaussian accelerated molecular dynamics. From the results, four compounds with the best molecular behavior and binding energy were selected for experimental testing, one of which presented inhibitory activity with a Ki value of 48 ± 5 μM. Through virtual screening, we identified a significant starting point for drug development, shedding new light on DCM compounds.

Abstract

Pressure sores are a common complication after spinal cord injury. But great advances in their management (nursing care, prevention and surgery) have been made in the last four decades. Neglected pressure ulcers may affect the adjacent joint, leading to septic arthritis. We report a paraplegic patient with a large trochanteric sore with hip arthritis, in whom we performed an upper femoral resection and acetabular curettage (Girdlestone's technique) and coverage with the homolateral vastus lateralis muscle flap in one stage. Some questions pertaining to this operation are discussed and there is a comparison with other ways of management described in the literature. We conclude that a successful outcome with the management of such large sores depends on a radical, aggressive operation to remove all of the affected tissue, and ensure a safe coverage with a reliable, viable muscle flap. The collaboration and the positive attitude of the patient towards the procedure and the result obtained are decisive in preventing recurrences.
