ABSTRACT
ABSTRACT Objective: To assess the influence of the COVID-19 pandemic on hospital admissions (HA), intra-hospital deaths (HD), and intra-hospital lethality rates (HL) related to respiratory diseases (RD) other than COVID-19 in Brazil. Methods: This observational time-series study was conducted through comparative analyses of the HA, HD, and HL related to non-COVID-19 RD registered between March and December 2020 by the Brazilian Unified Public Health System on the DataSUS Tabnet platform, using as reference the values recorded in the same period of 2019 and those projected by linear regression methods for 2020, considering the period from 2015 to 2019. The adopted statistical significance level was 5% (p < 0.05). Results: Compared to 2019, in 2020, there was a 42% decrease in HA and a 7.4% decrease in total HD related to non-COVID-19 RD, followed by a 60% increase in HL associated with this group of diseases. The HA and HL registered in 2020 differed significantly from the projected trend for that year by linear regression (p < 0.05). Of note, a significant reduction in hospitalizations due to asthma (-46%), chronic obstructive pulmonary disease (-45%), bronchiectasis (-54%), pneumonia (-46%), and acute bronchitis (-73%) was observed. Conclusions: During the first 8 months of the pandemic, there was a decline in HA and an increase in HL related to non-COVID-19 RD in Brazil, which can hypothetically reflect logistical challenges and delays in the management of this group of diseases.
RESUMO Objetivo: Avaliar a influência da pandemia de COVID-19 nas taxas de internações hospitalares (IH), óbitos intra-hospitalares (OH) e letalidade intra-hospitalar (LH) relacionadas a outras doenças respiratórias (DR) que não a COVID-19 no Brasil. Métodos: Este estudo observacional de série temporal foi realizado por meio da análise comparativa das IH, OH e LH relacionadas a DR não COVID-19 registradas entre março e dezembro de 2020 pelo Sistema Único de Saúde na plataforma DataSUS Tabnet, tendo como referência o valores registrados no mesmo período de 2019 e aqueles projetados pelos métodos de regressão linear para 2020, considerando o período de 2015 a 2019. O nível de significância estatística adotado foi de 5% (p < 0,05). Resultados: Comparado a 2019, em 2020, houve uma redução de 42% nas IH e de 7,4% nos OH totais relacionados a DR não COVID-19, seguido de um aumento de 60% nas taxas de LH associadas a esse grupo de doenças. As IH e as taxas de LH registradas em 2020 diferiram significantemente da tendência projetada para aquele ano por regressão linear (p < 0,05). Vale ressaltar que foi observada uma redução significativa das internações por asma (-46%), doença pulmonar obstrutiva crônica (-45%), bronquiectasia (-54%), pneumonia (-46%) e bronquite aguda (-73%). Conclusão: Durante os primeiros 8 meses da pandemia, houve um declínio nas IH e um aumento das taxas de LH relacionadas a DR não COVID-19 no Brasil, o que pode, hipoteticamente, refletir desafios logísticos e atrasos no manejo desse grupo de doenças.
ABSTRACT
OBJECTIVE: To investigate the relationship between lung lesion burden (LLB) found on chest computed tomography (CT) and 30-day mortality in hospitalized patients with high clinical suspicion of coronavirus disease 2019 (COVID-19), accounting for tomographic dynamic changes. METHODS: Patients hospitalized with high clinical suspicion of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in a dedicated and reference hospital for COVID-19, having undergone at least one RT-PCR test, regardless of the result, and with one CT compatible with COVID-19, were retrospectively studied. Clinical and laboratory data upon admission were assessed, and LLB found on CT was semi-quantitatively evaluated through visual analysis. The primary outcome was 30-day mortality after admission. Secondary outcomes, including the intensive care unit (ICU) admission, mechanical ventilation used, and length of stay (LOS), were assessed. RESULTS: A total of 457 patients with a mean age of 57±15 years were included. Among these, 58% presented with positive RT-PCR result for COVID-19. The median time from symptom onset to RT-PCR was 8 days [interquartile range 6-11 days]. An initial LLB of ≥50% using CT was found in 201 patients (44%), which was associated with an increased crude at 30-day mortality (31% vs. 15% in patients with LLB of <50%, p<0.001). An LLB of ≥50% was also associated with an increase in the ICU admission, the need for mechanical ventilation, and a prolonged LOS after adjusting for baseline covariates and accounting for the CT findings as a time-varying covariate; hence, patients with an LLB of ≥50% remained at a higher risk at 30-day mortality (adjusted hazard ratio 2.17, 95% confidence interval 1.47-3.18, p<0.001). CONCLUSION: Even after accounting for dynamic CT changes in patients with both clinical and imaging findings consistent with COVID-19, an LLB of ≥50% might be associated with a higher risk of mortality.

Tumores miofibroblásticos inflamatórios raramente acometem vias urinárias ou crianças, comumente mimetizando neoplasias malignas nos exames de imagem. Foram descritos apenas 35 casos desses tumores na bexiga de crianças, segundo a literatura recente. Os autores apresentam o caso de uma criança com um tumor miofibroblástico vesical que evoluiu favoravelmente após ressecção cirúrgica completa.
Inflammatory myofibroblastic tumors rarely affect the urinary tract or children, and frequently mimic malignancy on imaging studies. According to the recent literature, only 35 cases of such bladder tumors in children have been reported. The authors present the case of a child with a bladder myofibroblastic tumor with favorable progression following complete surgical resection.
