COVID-19 in real world: Survival and medical costs of hospitalized patients in Brazil´s first wave.

OBJECTIVE: To evaluate survival and direct medical costs of patients admitted in private hospitals with COVID-19 during the first wave. METHODS: A retrospective, observational study analyzing survival and the economic data retrieved on hospitalized patients with COVID-19. Data from March 2020 to December 2020. The direct cost of hospitalization was estimated using the microcosting method with each individual hospitalization. RESULTS: 342 cases were evaluated. Median age of 61.0 (95% CI 57.0‒65.0). 194 (56.7%) were men. The mortality rate was higher in the female sex (p = 0.0037), ICU (p < 0.001), mechanical ventilation (p<0.001) and elderly groups. 143 (41.8%) patients were admitted to the ICU (95% CI 36.6%-47.1%), of which 60 (41.9%) required MV (95% CI 34.0%-50.0%). Global LOS presented median of 6.7 days (95% CI 6.0-7.2). Mean costs were US$ 7,060,00 (95% CI 5,300.94-8,819,00) for each patient. Mean cost for patients discharged alive and patients deceased was US$ 5,475.53 (95% CI 3,692.91-7,258.14) and US$ 12,955.19 (95% CI 8,106.61-17,803.76), respectively (p < 0.001). CONCLUSIONS: Patients admitted with COVID-19 in these private hospitals point to great economic impact, mainly in the elderly and high-risk patients. It is key to better understand such costs in order to be prepared to make wise decisions during the current and future global health emergencies.

An integrative review of sequelae of COVID-19 / Uma revisão integrativa das sequelas da COVID-19 / Una revisión integradora de las secuelas del COVID-19

Objetivo: Identificar na literatura disponível as sequelas de saúde desenvolvidas pela população adoecida pela COVID-19. Métodos: Revisão integrativa com publicações recuperadas a partir do acesso ao Medline via PubMed e ao Portal Regional da Biblioteca Virtual em Saúde (BVS) em abril de 2021 que responderam à questão norteadora: Quais as principais sequelas de saúde desenvolvidas pela população adoecida pela COVID-19?. A estratégia de busca incluiu os descritores: Coronavirus Infections, COVID-19, SARS-COV-2, Complications, Disease, Adult, Long COVID. Identificaram-se 348 publicações, 196 da BVS e 152 no PubMed. Após análise dos critérios de inclusão/exclusão, permaneceram 66 publicações para leitura na íntegra, restando 27 artigos que compuseram a amostra. Resultados: As evidências selecionadas dos 27 artigos permitiram identificação das principais sequelas: neurológicas, saúde mental, cardíacas, no olfato e paladar, vasculares, cutâneas, respiratórias e gastrointestinais. A maior prevalência de sequelas neurológicas ocorreu em mulheres, bem como as cardíacas nos homens; não havendo distinção da prevalência de sintomas de saúde mental entre homens e mulheres. Conclusão: Com base nesses achados, evidenciou-se a importância do acompanhamento em longo prazo das pessoas que tiveram COVID-19, uma vez que os sintomas desenvolvidos como sequelas não são exclusivos dessa doença e podem impactar na qualidade de vida.

Objective: To identify, in the literature available, the health sequelae developed by the population affected by COVID-19. Methods: This is an integrative review of publications retrieved from Medline via PubMed and the Regional Portal of the Virtual Health Library (Biblioteca Virtual em Saúde ­ BVS) in April 2021 that answered the research question: What are the main health sequelae developed by the population affected by COVID-19? The search strategy included the descriptors: Coronavirus Infections, COVID-19, SARS-COV-2, Complications, Disease, Adult, Long COVID. 348 publications were identified: 196 on BVS and 152 on PubMed. After analyzing the inclusion/exclusion criteria, 66 publications remained for full reading, with a final 27 articles included in the sample. Results: The selected evidence from the 27 articles allowed the identification of the main sequelae: neurological, mental health, cardiac, smell and taste, vascular, cutaneous, respiratory and gastrointestinal sequelae. The highest prevalence of neurological sequelae was found in women, whereas cardiac sequelae were found mostly in men; there was no difference in the prevalence of mental health symptoms between men and women. Conclusion: Based on these findings, the importance of long-term follow-up of people who had COVID-19 was highlighted since the symptoms developed as sequelae are not exclusive to this disease and can impact quality of life.

Clinical trial and detection of SARS-CoV-2 by a commercial breath analysis test based on Terahertz technology.

Public health threats such as the current COVID-19 pandemics have required prompt action by the local, national, and international authorities. Rapid and noninvasive diagnostic methods may provide on-site detection and immediate social isolation, used as tools to rapidly control virus spreading. Accordingly, the aim of the present study was to evaluate a commercial breath analysis test (TERA.Bio®) and deterministic algorithm for detecting the SARS-CoV-2 spectral signature of Volatile Organic Compounds present in exhaled air samples of suspicious persons from southern Brazil. A casuistic total of 70 infected and 500 non-infected patients were sampled, tested, and results later compared to RT-qPCR as gold standard. Overall, the test showed 92.6% sensitivity and 96.0% specificity. No statistical correlation was observed between SARS-CoV-2 positivity and infection by other respiratory diseases. Further studies should focus on infection monitoring among asymptomatic persons. In conclusion, the breath analysis test herein may be used as a fast, on-site, and easy-to-apply screening method for diagnosing COVID-19.

Elective surgeries in the new normal post-COVID-19 pandemic: to test or do not test?

ABSTRACT The new coronavirus (SARS-CoV-2) pandemic has been wreaking havoc all over the planet. In a precautionary measure, populations have been forced and kept under quarantine to contain the outbreak of the COVID-19 disease. The quarantine primary goal is to avoid the overload to the hospitals, which should be available for the care of COVID-19 patients. However, the virus does not have a uniform spread throughout the planet, and Brazil is no different. Although all the world's attention is now on the COVID-19 pandemic, there is no similar pattern of spread, and other diseases are still a real problem. Given the risks of transmission between patients and healthcare providers, there is a great challenge for healthcare institutions who must balance resources to assure safe care to patients and professionals while they take care of other disease patients, and perform surgical procedures that need to be carried out. Under such circumstances, as COVID-19 can also present pre- or asymptomatic transmission, it can be challenging to identify patients who are carrying and spreading the virus. Studies and information on mandatory testing for who are candidates to undergo elective surgery are scarce. Thus, the authors have reviewed the literature, and discuss the need to test these patients under the current context. RESUMO A pandemia do novo coronavírus (SARS-CoV-2) vem causando estragos em todo o planeta. As populações estão sendo forçadas a quarentena - e assim mantidas - como medida de precaução para conter o surto da doença COVID-19. O principal objetivo da quarentena é evitar a sobrecarga dos hospitais, o que pode ser determinante para o atendimento aos pacientes COVID-19. O vírus não tem propagação uniforme pelo planeta, e no Brasil não é diferente. Contudo, as pessoas continuam a adoecer por outras causas não relacionadas ao SARS-CoV-2, demandando atendimento médico-hospitalar. Assim, os governos estão avaliando e liberando regiões para a realização de cirurgias eletivas em Estados e Municípios onde a COVID-19 está sob controle. Nesse contexto, há preocupação inerente à transmissão SARS-CoV-2 entre pacientes e prestadores de serviços de saúde, uma vez que há poucas informações sobre testes obrigatórios a serem realizados em pacientes com indicação cirúrgica. Esse problema é causado principalmente porque todos os pacientes durante o período de incubação são assintomáticos e, portanto, difíceis de serem avaliados. Assim sendo, os autores avaliam a literatura pertinente à microbiologia do SARS-CoV-2 e discutem a necessidade de testar esses pacientes com testes mais utilizados até o momento.
