Resumen Conocer la estabilidad de las muestras biológicas es esencial para obtener resultados confiables en el laboratorio de análisis clínicos. La Norma IRAM-ISO 15189:2023 establece que cada laboratorio debe estandarizar las condiciones de almacenamiento de las muestras. El objetivo de este trabajo fue determinar el tiempo y la temperatura óptimos para conservar muestras sanguíneas para la determinación de parámetros hematológicos en un analizador Sysmex XN 1000. Se procesaron muestras de sangre entera conservadas hasta 48 horas a temperatura ambiente y hasta 72 horas en heladera. De acuerdo a los resultados, para la determinación del hemograma, las muestras almacenadas a temperatura ambiente deben procesarse dentro de las 6-8 horas posextracción; los parámetros limitantes son aquellos influenciados por cambios en el volumen eritrocitario. En las muestras conservadas en heladera el análisis puede retrasarse hasta 48 horas y el recuento de plaquetas es el parámetro menos estable.

Resumo Conhecer a estabilidade das amostras biológicas é essencial para obter resultados confiáveis no laboratório de exames clínicas. A Norma IRAM-ISO 15189:2023 estabelece que cada laboratório deve padronizar as condições de armazenamento das amostras. O objetivo deste trabalho foi determinar o tempo e a temperatura ideais para preservar amostras de sangue para a determinação de parâmetros hematológicos em um analisador em um Sysmex XN 1000. Para isso, foram processadas amostras de sangue total armazenadas por até 48 horas em temperatura ambiente e por até 72 horas em geladeira. De acordo com os resultados obtidos, para a determinação do hemograma, as amostras armazenadas em temperatura ambiente devem ser processadas dentro de 6-8 horas após a extração, sendo os parâmetros limitantes aqueles influenciados por alterações no volume eritrocitário. Nas amostras armazenadas em geladeira, a análise pode demorar até 48 horas, sendo a contagem de plaquetas o parâmetro menos estável.

Abstract Knowing sample stability is essential to obtain reliable results in the clinical laboratory. The IRAM-ISO 15189:2023 Standard establishes that each laboratory must standardise the storage conditions of biological samples. This study was conducted to investigate the stability of haematological parameters using a Sysmex XN 1000 in samples stored for up to 48-72 hours at different temperatures. According to these results, the hematologic analytes should be processed in this laboratory within 6-8 hours after extraction if they are stored at room temperature. The limiting parameters are those influenced by changes in the erythrocyte volume. If storage is in a refrigerator, the analysis can be delayed up to 48 hours, being platelet count the limiting parameter.

Resumo A população em situação de rua cresce constantemente, sendo composta por uma grande diversidade de pessoas que estão diariamente expostas às diversas formas de violência, são privadas de direitos fundamentais, não possuem privacidade, têm condições precárias de sono, alimentação e higiene, a maioria faz uso abusivo de álcool e outras drogas. Objetivo: Interpretar como é desenvolvido o cuidado ofertado à população em situação de rua frente ao uso abusivo de álcool e outras drogas. Método: estudo qualitativo, realizado no período de outubro de 2021 a fevereiro de 2022, a partir de 20 entrevistas com profissionais de diferentes serviços da rede de atenção à saúde e de assistência e desenvolvimento social de um interior paulista, por meio da análise temática, utilizando-se da ferramenta NVivo. Resultados: foram identificados os temas: a situação de viver na rua favorece o uso de álcool e outras drogas; incipiente efetivação da Rede de Atenção Psicossocial (RAPS); incipiente efetivação da Política de Redução de Danos e Influência do terceiro setor no cuidado à PSR. Considerações Finais: Evidenciam-se limites para a promoção do cuidado na perspectiva da atenção psicossocial, sendo que para avançar é necessário dar voz e considerar as especificidades da PSR, compreender suas concepções do processo de saúde-doença e suas trajetórias.

Abstract The Homeless people is constantly growing, being made up of a wide range of people who are daily exposed to different forms of violence, are deprived of fundamental rights, lack privacy, have precarious conditions of sleep, food and hygiene. Objective: To understand/interpret how the care offered to the homeless population is developed in relation to the abusive use of alcohol and other drugs. Method: qualitative study, carried out from October 2021 to February 2022, based on 20 interviews with professionals from different services in the health care and assistance and social development network in an interior of São Paulo, through thematic analysis, using the NVivo tool. Results: the themes were identified: the situation of living on the street favors the use of alcohol and other drugs; care proposals centered on abstinence; hospitalization and medicalization weaken the continuity of care; incipient implementation of the Policy of Harm Reduction and Influence of the third sector in the care of PSR. Conclusions: Limits are evident for the promotion of care from the perspective of psychosocial care, and to advance it is necessary to give voice and consider the specificities of HP, understand its conceptions of the health-disease process and its trajectories.

ABSTRACT Objective: To update the recommendations to support decisions regarding the pharmacological treatment of patients hospitalized with COVID-19 in Brazil. Methods: Experts, including representatives of the Ministry of Health and methodologists, created this guideline. The method used for the rapid development of guidelines was based on the adoption and/or adaptation of existing international guidelines (GRADE ADOLOPMENT) and supported by the e-COVID-19 RecMap platform. The quality of the evidence and the preparation of the recommendations followed the GRADE method. Results: Twenty-one recommendations were generated, including strong recommendations for the use of corticosteroids in patients using supplemental oxygen and conditional recommendations for the use of tocilizumab and baricitinib for patients on supplemental oxygen or on noninvasive ventilation and anticoagulants to prevent thromboembolism. Due to suspension of use authorization, it was not possible to make recommendations regarding the use of casirivimab + imdevimab. Strong recommendations against the use of azithromycin in patients without suspected bacterial infection, hydroxychloroquine, convalescent plasma, colchicine, and lopinavir + ritonavir and conditional recommendations against the use of ivermectin and remdesivir were made. Conclusion: New recommendations for the treatment of hospitalized patients with COVID-19 were generated, such as those for tocilizumab and baricitinib. Corticosteroids and prophylaxis for thromboembolism are still recommended, the latter with conditional recommendation. Several drugs were considered ineffective and should not be used to provide the best treatment according to the principles of evidence-based medicine and to promote resource economy.

RESUMO Objetivo: Atualizar as recomendações para embasar as decisões para o tratamento farmacológico de pacientes hospitalizados com COVID-19 no Brasil. Métodos: A elaboração desta diretriz foi feita por especialistas, incluindo representantes do Ministério da Saúde e metodologistas. O método utilizado para o desenvolvimento rápido de diretrizes baseou-se na adoção e/ou adaptação de diretrizes internacionais existentes (GRADE ADOLOPMENT) e contou com o apoio da plataforma e-COVID-19 RecMap. A qualidade das evidências e a elaboração das recomendações seguiram o método GRADE. Resultados: Chegaram-se a 21 recomendações, incluindo recomendações fortes quanto ao uso de corticosteroides em pacientes em uso de oxigênio suplementar e recomendações condicionais para o uso de tocilizumabe e baricitinibe, em pacientes com oxigênio suplementar ou ventilação não invasiva, e de anticoagulantes, para prevenção de tromboembolismo. Devido à suspensão da autorização de uso, não foi possível fazer recomendações para o tratamento com casirivimabe + imdevimabe. Foram feitas recomendações fortes contra o uso de azitromicina em pacientes sem suspeita de infecção bacteriana, hidroxicloroquina, plasma convalescente, colchicina e lopinavir + ritonavir, além de recomendações condicionais contra o uso de ivermectina e rendesivir. Conclusão: Foram criadas novas recomendações para o tratamento de pacientes hospitalizados com COVID-19, como as recomendações de tocilizumabe e baricitinibe. Ainda são recomendados corticosteroides e profilaxia contra tromboembolismo, esta em caráter condicional. Vários medicamentos foram considerados ineficazes e não devem ser usados, no intuito de proporcionar o melhor tratamento segundo os princípios da medicina baseada em evidências e promover a economia de recursos.

ABSTRACT BACKGROUND: The Hip Sports Activity Scale (HSAS) is a hip-specific instrument for assessing the present levels of physical activity among patients with femoroacetabular impingement (FAI) syndrome. When evaluating treatment outcomes in patients with FAI syndrome, it is necessary to use joint-specific instruments and ones that can evaluate the levels of physical activity in these patients, such as the HSAS-Brazil. OBJECTIVE: To validate the HSAS-Brazil among a group of physically active patients after arthroscopic treatment of FAI syndrome. DESIGN AND SETTING: Cross-sectional research of quantitative and qualitative types using data obtained from July 2018 to October 2019. METHODS: A total of 58 patients of both genders diagnosed with FAI syndrome and who had undergone hip arthroscopy participated in this research. To establish reliability and validity, patients first answered the Brazilian versions of the 12-Item Short-Form Health Survey (SF-12), Nonarthritic Hip Score (NAHS), and HSAS; after a 48-hour interval, they answered the HSAS-Brazil again. RESULTS: For test-retest reliability, the interclass correlation was 0.908 (P < 0.001). The HSAS-Brazil correlated to the NAHS-Brazil (r = 0.63, P < 0.001), as well as the SF-12 (Physical Health) (r = 0.42, P = 0.001). CONCLUSION: The HSAS-Brazil was validated and proved to be a reliable and valid scale to assess sports activity levels in physically active patients with FAI syndrome after arthroscopic treatment.

Abstract Objective: To assess factors associated with emotional changes and Hyperactivity/Inattention (HI) motivated by COVID-19 quarantine in adolescents with immunocompromising diseases. Methods: A cross-sectional study included 343 adolescents with immunocompromising diseases and 108 healthy adolescents. Online questionnaires were answered including socio-demographic data and self-rated healthcare routine during COVID-19 quarantine and validated surveys: Strengths and Difficulties Questionnaire (SDQ), Pittsburgh Sleep Quality Index (PSQI), Pediatric Quality of Life Inventory 4.0 (PedsQL4.0). Results: The frequencies of abnormal emotional SDQ scores from adolescents with chronic diseases were similar to those of healthy subjects (110/343 [32%] vs. 38/108 [35%], p = 0.548), as well as abnormal hyperactivity/inattention SDQ scores (79/343 [23%] vs. 29/108 [27%], p = 0.417). Logistic regression analysis of independent variables associated with abnormal emotional scores from adolescents with chronic diseases showed: female sex (Odds Ratio [OR = 3.76]; 95% Confidence Interval (95% CI) 2.00–7.05; p < 0.001), poor sleep quality (OR = 2.05; 95% CI 1.08–3.88; p = 0.028) and intrafamilial violence during pandemic (OR = 2.17; 95% CI 1.12–4.19; p = 0.021) as independently associated with abnormal emotional scores, whereas total PedsQL score was inversely associated with abnormal emotional scores (OR = 0.95; 95% CI 0.93–0.96; p < 0.0001). Logistic regression analysis associated with abnormal HI scores from patients evidenced that total PedsQL score (OR = 0.97; 95% CI 0.95–0.99; p = 0.010], changes in medical appointments during the pandemic (OR = 0.39; 95% CI 0.19–0.79; p = 0.021), and reliable COVID-19 information (OR = 0.35; 95% CI 0.16–0.77; p = 0.026) remained inversely associated with abnormal HI scores. Conclusion: The present study showed emotional and HI disturbances in adolescents with chronic immunosuppressive diseases during the COVID-19 pandemic. It reinforces the need to promptly implement a longitudinal program to protect the mental health of adolescents with and without chronic illnesses during future pandemics.

Abstract Pitaya is a rich source of bioactive compounds, such as polyphenols and betalains. Moreover, these compounds has been associated with reduced risk of type 2 diabetes mellitus. The aim of this study is to evaluate the effect of this fruit on glycemia and oxidative stress in aloxan-induced diabetic mice. Thus, considering that In the in vivo assays, the mice were divided into 5 groups (n = 6): (a) healthy group treated with water; (b) diabetic mice treated with metformin at 200 mg/kg body weight diluted in water; (c) untreated diabetic mice; (d) diabetic mice treated with pitaya at 200 mg/kg and (e) diabetic mice treated with pitaya at 400 mg/kg of body weight diluted in water. The results shows that pitaya was able significantly to reduce blood glucose (p < 0.05) (200 mg/kg); significantly reduce cholesterol (200 and 400 mg/kg) and significantly increase HDL-c (400 mg/kg) levels. In the oxidative stress experiment, Malondialdehyde levels in the liver were significantly reduced (p < 0.05) in the groups treated with pitaya, when compared to the other groups, suggesting lower lipid peroxidation. The consumption of pitaya reduced the blood glucose and cholesterol and increase the HDL, in addition, the lipid peroxidation - which is common in diabetic patients, was reduced.

Abstract Background Cardiovascular complications of COVID-19 are important aspects of the disease’s pathogenesis and prognosis. Evidence on the prognostic role of troponin and myocardial injury in Latin American hospitalized COVID-19 patients is still scarce. Objectives To evaluate myocardial injury as independent predictor of in-hospital mortality and invasive mechanical ventilation support in hospitalized patients, from the Brazilian COVID-19 Registry. Methods This cohort study is a substudy of the Brazilian COVID-19 Registry, conducted in 31 Brazilian hospitals of 17 cities, March-September 2020. Primary outcomes included in-hospital mortality and invasive mechanical ventilation support. Models for the primary outcomes were estimated by Poisson regression with robust variance, with statistical significance of p<0.05. Results Of 2,925 patients (median age of 60 years [48-71], 57.1% men), 27.3% presented myocardial injury. The proportion of patients with comorbidities was higher among patients with cardiac injury (median 2 [1-2] vs. 1 [0-2]). Patients with myocardial injury had higher median levels of brain natriuretic peptide, lactate dehydrogenase, creatine phosphokinase, N-terminal pro-brain natriuretic peptide, and C-reactive protein than patients without myocardial injury. As independent predictors, C-reactive protein and platelet counts were related to the risk of death, and neutrophils and platelet counts were related to the risk of invasive mechanical ventilation support. Patients with high troponin levels presented a higher risk of death (RR 2.03, 95% CI 1.60-2.58) and invasive mechanical ventilation support (RR 1.87, 95% CI 1.57-2.23), when compared to those with normal troponin levels. Conclusion Cardiac injury was an independent predictor of in-hospital mortality and the need for invasive mechanical ventilation support in hospitalized COVID-19 patients.

Resumo Fundamento As complicações cardiovasculares da COVID-19 são aspectos importantes da patogênese e do prognóstico da doença. Evidências do papel prognóstico da troponina e da lesão miocárdica em pacientes hospitalizados com COVID-19 na América Latina são ainda escassos. Objetivos Avaliar a lesão miocárdica como preditor independente de mortalidade hospitalar e suporte ventilatório mecânico em pacientes hospitalizados, do registro brasileiro de COVID-19. Métodos Este estudo coorte é um subestudo do registro brasileiro de COVID-19, conduzido em 31 hospitais brasileiros de 17 cidades, de março a setembro de 2020. Os desfechos primários incluíram mortalidade hospitalar e suporte ventilatório mecânico invasivo. Os modelos para os desfechos primários foram estimados por regressão de Poisson com variância robusta, com significância estatística de p<0,05. Resultados Dos 2925 pacientes [idade mediana de 60 anos (48-71), 57,1%], 27,3% apresentaram lesão miocárdica. A proporção de pacientes com comorbidades foi maior nos pacientes com lesão miocárdica [mediana 2 (1-2) vs. 1 (0-20)]. Os pacientes com lesão miocárdica apresentaram maiores valores medianos de peptídeo natriurético cerebral, lactato desidrogenase, creatina fosfoquinase, N-terminal do pró-peptídeo natriurético tipo B e proteína C reativa em comparação a pacientes sem lesão miocárdica. Como fatores independentes, proteína C reativa e contagem de plaquetas foram relacionados com o risco de morte, e neutrófilos e contagem de plaquetas foram relacionados ao risco de suporte ventilatório mecânico invasivo. Os pacientes com níveis elevados de troponina apresentaram um maior risco de morte (RR 2,03, IC95% 1,60-2,58) e suporte ventilatório mecânico (RR 1,87;IC95% 1,57-2,23), em comparação àqueles com níveis de troponina normais. Conclusão Lesão cardíaca foi um preditor independente de mortalidade hospitalar e necessidade de suporte ventilatório mecânico em pacientes hospitalizados com COVID-19.

Abstract This study aimed to verify the impact of high-fat diet consumption for a prolonged period on oxidative stress, fetal growth, umbilical vascular system, and placental structures in pregnant goats. Twenty-two pregnant goats were grouped into the control diet (n= 11) and fat diet (n = 11). Flaxseed meal was added to the fat diet, replacing the corn grain of concentrate, from gestational day 100 to delivery date. Diets were isonitrogenous and isoenergetic, differing in fat content (2.8% vs. 6.3% dry matter). The fat group showed higher feed intake and total plasma lipid levels than the control group (P < 0.001). No difference was found in placentome, and umbilical vascular development. Fat diet-fed goats exhibited a lower systolic peak in the umbilical artery. At delivery, placental traits were similar with the exception of the cotyledon width (P = 0.0075), which was smaller in the fat group and cotyledon surface (P = 0.0047) for multiple pregnancy of fat diet. Cotyledonary epithelium showed more intense staining of lipid droplets and a greater area for lipofuscin staining in the fat group compared to control group (P < 0.001). The mean live weight of the kids was lower in the fat group in the first week after delivery than in control group. Thus, in goats, the continuous administration of a high-fat diet during pregnancy does not appear to modify the fetal-maternal vascular structures but has an impact on a part of the placental structure; therefore, its use must be carefully evaluated.

ABSTRACT A male infant presented with progressive jaundice immediately after birth. Fecal acholia and choluria associated with extensive bullous skin lesions in his trunk, abdomen, and upper and lower limbs developed during phototherapy. Several diagnostic hypotheses were presented, including neonatal porphyria, hemochromatosis, Alagille syndrome, and neonatal lupus. A 24-hour urine sample for the dosage of urinary porphyrins was collected, showing high results (1823.6µg in 100mL). At 50 days of life, fluorescence spectroscopy using a Wood’s lamp revealed simultaneous bright red fluorescence of urine-stained diapers and sample blood. A definitive diagnosis of congenital erythropoietic porphyria was made following identification of a mutation of the uroporphyrinogen synthetases III gene on genetic testing. The patient was subsequently maintained in a low light environment since then, resulting in improvement of the lesions. Congenital erythropoietic porphyria is a disease of the group of porphyrias that presents shortly after birth with blistering occurring in regions exposed to the sun or other ultraviolet light. Atrophic scars, mutilated fingers, and bright red fluorescence of the urine and teeth may also be observed. There is no specific treatment, and prophylaxis comprising a total avoidance of sunlight is generally recommended. A high degree of suspicion is required for diagnosis. An early diagnosis can lead to less damage. Here, we present the case of a newborn with congenital erythropoietic porphyria diagnosed after presenting with bullous lesions secondary to phototherapy.

BACKGROUND Chikungunya is a mosquito-borne virus that has been causing large outbreaks in the Americas since 2014. In Brazil, Asian-Caribbean (AC) and East-Central-South-African (ECSA) genotypes have been detected and lead to large outbreaks in several Brazilian states. In Rio Grande do Sul (RS), the southernmost state of Brazil, the first cases were reported in 2016. OBJECTIVES AND METHODS We employed genome sequencing and epidemiological investigation to characterise the Chikungunya fever (CHIKF) burden in RS between 2017-2021. FINDINGS We detected an increasing CHIKF burden linked to travel associated introductions and communitary transmission of distinct lineages of the ECSA genotype during this period. MAIN CONCLUSIONS Until 2020, CHIKV introductions were most travel associated and transmission was limited. Then, in 2021, the largest outbreak occurred in the state associated with the introduction of a new ECSA lineage. CHIKV outbreaks are likely to occur in the near future due to abundant competent vectors and a susceptible population, exposing more than 11 million inhabitants to an increasing infection risk.

Abstract Introduction Fibromyalgia is a complex, generalized, and diffuse chronic musculoskeletal pain. Pharmacological approaches are widely used to relieve pain and increase quality of life. Low-Dose Naltrexone (LDN) was shown to increase the nociceptive threshold in patients with fibromyalgia. Transcranial Direct Current Stimulation (tDCS) is effective for pain management. Objective The purpose of this study was to evaluate the analgesic and neuromodulatory effects of a combination of LDN and tDCS in patients with fibromyalgia. Methods This was a randomized, double-blinded, parallel, placebo/sham-controlled trial (NCT04502251; RBR-7HK8N) in which 86 women with fibromyalgia were included, and written informed consent was obtained from them. The patients were allocated into four groups: LDN + tDCS (n = 21), LDN + tDCS Sham (n = 22), placebo + tDCS (n = 22), and placebo+tDCS Sham (n = 21). The LDN or placebo (p.o.) intervention lasted 26 days; in the last five sessions, tDCS was applied (sham or active, 20 min, 2 mA). The following categories were assessed: sociodemographic, Visual Analog Pain Scale (VAS), Pain Catastrophizing Scale (PCS), State-Trait Anxiety Inventory (STAI), Fibromyalgia Impact Questionnaire (FIQ), Beck Depression Inventory (BDI-II), Profile of Chronic Pain Scale (PCP:S), Pain Pressure Threshold (PPT), and Conditioned Pain Modulation (CPM). Blood samples were collected to analyze BDNF serum levels. Results At baseline, no significant difference was found regarding all measurements. VAS pain was significantly reduced in the LDN + tDCS (p = 0.010), LDN + tDCS Sham (p= 0.001), and placebo+tDCS Sham (p= 0.009) groups. In the PCP:S, the LDN+tDCS group showed reduced pain frequency and intensity (p= 0.001), effect of pain on activities (p= 0.014) and emotions (p= 0.008). Depressive symptoms reduced after all active interventions (p > 0.001). Conclusion Combined LDN+tDCS has possible benefits in reducing pain frequency and intensity; however, a placebo effect was observed in pain using VAS, and further studies should be performed to analyze the possible association.

Abstract Background The long-term effects of mild COVID-19 on physical, cognitive, and mental health are not yet well understood. Objective The purpose of this paper is to describe the protocol for the ongoing “Post-COVID Brazil” study 2, which aims to evaluate the factors associated with health-related quality of life and long-term cardiovascular and non-cardiovascular outcomes one year after a mild episode of symptomatic COVID-19. Methods The “Post-COVID Brazil” study 2 is a prospective multicenter study that plans to enroll 1047 patients (NCT05197647). Centralized, structured telephone interviews are conducted at 1, 3, 6, 9, and 12 months after COVID-19 diagnosis. The primary outcome is the health-related quality-of-life utility score, assessed using the EuroQol-5D-3L (EQ-5D-3L) questionnaire at 12 months. Secondary endpoints include the EQ-5D-3L at 3, 6, and 9 months, as well as all-cause mortality, major cardiovascular events, hospitalization, return to work or education, persistent symptoms, new disabilities in instrumental activities of daily living, cognitive impairment, anxiety, depression, and post-traumatic stress symptoms at 3, 6, 9, and 12 months after SARS-CoV-2 infection. A p-value < 0.05 will be considered statistically significant for all analyses. Results The primary endpoint will be presented as the overall frequency of the EQ-5D-3L domains 12 months after SARS-CoV-2 infection. Main analysis will explore the association of independent variables with the study outcomes. Conclusion The “Post-COVID Brazil” study 2 aims to clarify the impact of long COVID on the quality of life and cardiovascular and non-cardiovascular outcomes of Brazilian patients who have had mild COVID-19.

Resumo Fundamento Os efeitos em longo prazo da COVID-19 leve sobre a saúde física, mental e cognitiva ainda não são bem conhecidos. Objetivo Este artigo visa descrever o protocolo para o estudo em andamento Pós-COVID Brasil 2, o qual tem como objetivo avaliar os fatores associados à qualidade de vida associada à saúde e desfechos cardiovasculares e não cardiovasculares de longo prazo um ano após um episódio de COVID-19 sintomática leve. Métodos O estudo “Pós-COVID Brasil 2” é um estudo multicêntrico prospectivo que pretende incluir 1047 pacientes (NCT05197647). Entrevistas estruturas, centralizadas são conduzidas em um mês, e aos três, seis, nove e 12 meses após o diagnóstico de COVID-19. O desfecho primário é o escore de utilidade da qualidade de vida relacionada à saúde, avaliado usando o questionário EuroQol-5D-3L (EQ-5D-3L) aos 12 meses. Desfechos secundários incluem o EQ-5D-3L aos três, seis e nove meses, mortalidade por todas as causas, eventos cardiovasculares maiores, hospitalização, retorno ao trabalho ou à escola, sintomas persistentes, novas incapacidades em atividades instrumentais diárias, déficit cognitivo, ansiedade, depressão, e sintomas de transtorno do estresse pós-traumático as três, seis, nove e doze meses após a infecção pelo SARS-CoV-2. Um valor de p<0,05 será considerado estatisticamente significativo para as análises. Resultados O desfecho primário será apresentado como frequência dos domínios do EQ-5D-3L doze meses após a infecção por SARS-CoV-2. A análise principal explorará a associação das variáveis independentes com os desfechos do estudo. Conclusão O estudo “Pós-COVID Brasil 2” tem como objetivo elucidar o impacto da COVID longa sobre a qualidade de vida e desfechos cardiovasculares e não cardiovasculares de brasileiros pacientes que apresentaram COVID-19 leve.
