RESUMO
SUMMARY OBJECTIVE: This study aimed to analyze the clinical-epidemiological profile, possible risk predictors, and outcomes of patients with coronavirus disease 2019 admitted to the ward of a tertiary care hospital in southern Brazil. Specifically, we describe the demographic characteristics, comorbidities, baseline laboratory findings, clinical course, and survival of these patients. METHODS: This is an observational, retrospective cohort study, performed from January to March 2022, on medical records of patients hospitalized between April 2020 and December 2021 in the coronavirus disease 2019 ward of a tertiary hospital in southern Brazil. RESULTS: Data from 502 hospitalized patients were analyzed, of which 60.2% were male, with a median age of 56 years and 31.7% were over 65 years old. The main symptoms presented were dyspnea/respiratory discomfort (69.9%) and cough (63.1%). The most common comorbidities were obesity, systemic arterial hypertension, and diabetes mellitus. A proportion of 55.8% of 493 patients had PaO2/FiO2<300 mmHg in the first examination performed after admission and 46.0% had a neutrophil/lymphocyte ratio>6.8. Oxygen therapy by Venturi mask or mask with reservoir was used in 34.7% of the patients, and non-invasive ventilation was used in 10.0% of the patients. The majority of the patients (98.4%) used corticosteroids, and the outcome of 82.5% of the hospitalized patients was home discharge. CONCLUSION: After analyzing the clinical and epidemiological profile, it can be concluded that age greater than 65 years and pulmonary involvement >50% are predictors of a worse prognosis for coronavirus disease 2019, as is the need for high-flow oxygen therapy. Corticotherapy, however, proved to be beneficial in the treatment of the disease.
RESUMO
A persistência da veia cava superior esquerda é rara, principalmente quando associada a ausência da veiacava superior direita, e mais ainda quando associada a síndrome bradicardia-taquicardia. Relata-se o caso em queo diagnóstico dessa anomalia venosa foi feito durante o implante de marcapasso cardíaco artificial definitivo paratratamento de síndrome bradicardia-taquicardia. O paciente havia sido submetido a transplante renal e apresentavafunção renal limítrofe, razão pela qual se optou por não utilizar contraste para realização de venografia, dandopreferência à análise do trajeto do fio guia.
Persistent left superior vena cava is a rare anomaly, mainly when associated with absent right superiorvena cava, especially when associated with bradycardia-tachycardia syndrome. We report the case of a patient,whose diagnosis of venous anomaly was made during definitive artificial pacemaker implantation for treatment ofbradycardia-tachycardia syndrome. The patient had been submitted to a kidney transplantation and had borderlinerenal function, and therefore we chose not to use a guidewire instead of contrast media to perform venography.
