RESUMO

Pseudolesions in bone and muscle are encountered mostly incidentally in routine imaging studies, especially due to the recent advancements on many different imaging modalities. These lesions can be categorized into the following categories: normal variants; congenital; iatrogenic; degenerative; and postoperative. In this review, we discuss the many different radiological characteristics of musculoskeletal pseudolesions that appear on imaging, which can prevent non-essential additional studies.

RESUMO

OBJECTIVES: Remdesivir is the current recommended anti-viral treatment in moderate-to-severe COVID-19. However, data on impact of timing of therapy, efficacy, and safety are limited. We evaluated the impact of timing of remdesivir initiation (symptom onset to remdesivir treatment [SORT] interval) on in-hospital all-cause mortality in patients with moderate-to-severe COVID-19. METHODS: This retrospective study was conducted between June 25 and October 3, 2020, at a tertiary care dedicated COVID center in India. Patients with moderate-to-severe COVID-19 (moderate: SpO2 <94%; severe: SpO2 <90%) were included. The main outcome was impact of SORT interval on in-hospital all-cause mortality. Subgroups were formed and analyzed based on SORT interval. RESULTS: Of 350 patients treated with remdesivir, 346 were included in the final analysis. Overall, 76 (22.0%) patients died (moderate: 3 [2.8%], severe: 73 [30.8%]). All-cause mortality was significantly lower in patients with SORT interval ≤9 days (n = 260) vs SORT interval >9 days (n = 86; 18.1% vs 33.7%; p = 0.004). The odds of death were significantly lower in patients with SORT interval ≤9 days vs >9 days (odds ratio = 0.43; 95% CI, 0.25-0.75; p = 0.003). CONCLUSION: Remdesivir initiation ≤9 days from symptom onset was associated with mortality benefit, defining a treatment window and reinforcing the need for appropriately-timed remdesivir in moderate-to-severe COVID-19.
