Prevalence of reported incidental adrenal findings in chest computerized tomography scans performed during the COVID-19 pandemic in a single center in Northeast Brazil.

Objective: We investigated the prevalence of adrenal incidentalomas (AIs) in a nonselected Brazilian population in chest computed tomography (CT) performed during the COVID-19 pandemic. Materials and methods: This was a retrospective cross-sectional observational study using chest CT reports from a tertiary in- and outpatient radiology clinic from March to September 2020. AIs were defined by changes in the shape, size, or density of the gland initially identified in the released report. Individuals with multiple studies were included, and duplicates were removed. Exams with positive findings were reviewed by a single radiologist. Results: A total of 10,329 chest CTs were reviewed, and after duplicate removal, 8,207 exams were included. The median age was 45 years [IQR 35-59 years], and 4,667 (56.8%) were female. Thirty-eight lesions were identified in 36 patients (prevalence 0.44%). A higher prevalence was observed with age, with 94.4% of the findings in patients aged 40 years and over (RR 9.98 IC 2.39-41.58, p 0.002), but there was no significant difference between the sexes. Seventeen lesions (44.7%) had more than 10 HU, and five lesions (12.1%) were more than 4 cm. Conclusion: The prevalence of AIs in an unselected and unreviewed population in a Brazilian clinic is low. The impact on the health system caused by AIs discovered during the pandemic should be small regarding the need for specialized follow-up.

High-touch surfaces disinfection compliance in a COVID-19 intensive care unit.

Environmental cleaning and disinfection are fundamental health care-associated infection prevention measures. This study aimed to evaluate the disinfection compliance of high-touch surfaces in a COVID-19-only intensive care unit, using a fluorescent marker. It was divided into 3 phases, baseline assessment, educational feedback, and post feedback. Disinfection compliance improved significantly from the first to the third phase, 14.3% to 51.4% (P < .001), respectively.

Synchronous psychological interventions by videoconferencing for caregivers of people with dementia: an integrative review.

The COVID-19 pandemic has created the need to develop psychological interventions to support people with dementia and their caregivers in the context of social distancing. This study sought to investigate, systematize, and report results of scientific studies published in the past 5 years on synchronous online psychological interventions using videoconferencing for informal caregivers of people with dementia. The PubMed, BIREME, and Web of Science databases were searched using the descriptors "caregiver," "dementia," "online," and "intervention." Six international studies were included in the review. Results demonstrated, in general, that this modality of intervention was acceptable, feasible, and promoted benefits for the health, quality of life, and well-being of caregivers. A need was identified for further studies investigating synchronous online interventions that include follow-up and a control group to further the evidence on the effectiveness and feasibility of this type of therapeutic intervention.

A pandemia da COVID-19 exigiu o desenvolvimento de intervenções psicológicas para apoiar as pessoas com demência e seus cuidadores no contexto de distanciamento social. No presente estudo, buscou-se investigar, sistematizar e apresentar resultados de pesquisas científicas produzidas nos últimos cinco anos sobre intervenções psicológicas online síncronas, por meio de videoconferência, com cuidadores informais de pessoas com demência. Para tanto, utilizaram-se as bases de dados PubMed, Centro Latino-Americano e do Caribe de Informação em Ciências da Saúde (BIREME) e Web of Science, por meio dos descritores "caregiver", "dementia", "online" e "intervention". Foram incluídos na revisão seis estudos internacionais que demonstraram, em geral, que essa modalidade de intervenção é aceitável, viável e passível de promover efeitos positivos na saúde, na qualidade de vida e no bem-estar dos cuidadores. Identificou-se a relevância de estudos futuros investigarem intervenções online síncronas com a implementação de medidas de follow-up e grupo controle, a fim de agregar mais evidências da efetividade e da viabilidade desse tipo de intervenção terapêutica.

Synchronous psychological interventions by videoconferencing for caregivers of people with dementia: an integrative review INTERVENÇÕES PSICOLÓGICAS SÍNCRONAS POR VIDEOCONFERÊNCIA PARA CUIDADORES DE PESSOAS COM DEMÊNCIA: UMA REVISÃO INTEGRATIVA

Effect of tocilizumab on clinical outcomes at 15 days in patients with severe or critical coronavirus disease 2019: randomised controlled trial.

OBJECTIVE: To determine whether tocilizumab improves clinical outcomes for patients with severe or critical coronavirus disease 2019 (covid-19). DESIGN: Randomised, open label trial. SETTING: Nine hospitals in Brazil, 8 May to 17 July 2020. PARTICIPANTS: Adults with confirmed covid-19 who were receiving supplemental oxygen or mechanical ventilation and had abnormal levels of at least two serum biomarkers (C reactive protein, D dimer, lactate dehydrogenase, or ferritin). The data monitoring committee recommended stopping the trial early, after 129 patients had been enrolled, because of an increased number of deaths at 15 days in the tocilizumab group. INTERVENTIONS: Tocilizumab (single intravenous infusion of 8 mg/kg) plus standard care (n=65) versus standard care alone (n=64). MAIN OUTCOME MEASURE: The primary outcome, clinical status measured at 15 days using a seven level ordinal scale, was analysed as a composite of death or mechanical ventilation because the assumption of odds proportionality was not met. RESULTS: A total of 129 patients were enrolled (mean age 57 (SD 14) years; 68% men) and all completed follow-up. All patients in the tocilizumab group and two in the standard care group received tocilizumab. 18 of 65 (28%) patients in the tocilizumab group and 13 of 64 (20%) in the standard care group were receiving mechanical ventilation or died at day 15 (odds ratio 1.54, 95% confidence interval 0.66 to 3.66; P=0.32). Death at 15 days occurred in 11 (17%) patients in the tocilizumab group compared with 2 (3%) in the standard care group (odds ratio 6.42, 95% confidence interval 1.59 to 43.2). Adverse events were reported in 29 of 67 (43%) patients who received tocilizumab and 21 of 62 (34%) who did not receive tocilizumab. CONCLUSIONS: In patients with severe or critical covid-19, tocilizumab plus standard care was not superior to standard care alone in improving clinical outcomes at 15 days, and it might increase mortality.
