ABSTRACT Objective To evaluate deaths, hospitalizations, and persistence of symptoms in patients with COVID-19 after infection in an outpatient setting during the first COVID-19 wave in Brazil. Methods This prospective cohort was between April 2020 and February 2021. Hospitalized or non-hospitalized COVID-19 patients until five days after symptom onset were included. The outcomes measured were incidence of death, hospitalization, and persistence of more than two symptoms 60 days after discharge. Results Out of 1,198 patients enrolled in the study, 66.7% were hospitalized. A total of 289 patients died (1 [0.3%] non-hospitalized and 288 [36%] hospitalized). At 60 days, patients non-hospitalized during admission had more persistent symptoms (16.2%) compared to hospitalized (37.1%). The COVID-19 severity variables associated with the persistence of two or more symptoms were increased age (OR= 1.03; p=0.015), respiratory rate at hospital admission (OR= 1.11; p=0.005), length of hospital stay of more than 60 days (OR= 12.24; p=0.026), and need for intensive care unit admission (OR= 2.04; p=0.038). Conclusion COVID-19 survivors who were older, tachypneic at admission, had a hospital length of stay >60 days, and were admitted to the intensive care unit had more persistent symptoms than patients who did not require hospitalization in the early COVID-19 waves.

RESUMO Objetivo: Estabelecer os aspectos clínicos de dores do crescimento e determinar, por meio de diagnóstico diferencial, quantos pacientes com essas dores foram espontaneamente a uma clínica especializada e obtiveram o diagnóstico de dores de crescimento. Métodos: Este estudo analisou prospectivamente a presença de dores do crescimento em uma população de crianças e adolescentes com sinais e sintomas (dores nos membros inferiores) de etiologia desconhecida. Resultados: Foram avaliados 345 crianças e adolescentes; 174 (50,4%) eram do sexo masculino e 171 (49,6%) do sexo feminino. Trezentos casos foram classificados como dor de crescimento (87%). Conclusão: Foi encontrada uma elevada frequência de dor de crescimento na população estudada e isso mostra que, em avaliação prospectiva de pacientes com sinais e sintomas de etiologia desconhecida, pode ser encontrada uma frequência maior de dores de crescimento do que a relatada na literatura.

ABSTRACT Objective: To establish the clinical aspects of growing pains and to determine, through differential diagnosis, how many patients who referred themselves to a specialized clinic were found to have growing pains. Methods: This study prospectively examined the presence of growing pains in a self-reported population of children and adolescents with signs and symptoms (lower limb pains) of unexplained etiology. Results: A total of 345 children and adolescents were evaluated; 174 (50.4%) were males and 171 (49.6%) were females. Three hundred cases were classified as growing pains (87%). Conclusion: A high frequency of growing pains was found in our study population and it shows that in a prospective evaluation of patients with signs and symptoms of unknown etiology we can find a frequency higher than that reported in literature.

RESUMO Objetivo: Conhecer o perfil dos pacientes submetidos à artroplastia de quadril e joelho em um período de dois anos e comparar os dados com relatos da literatura. Métodos: Foram revisados 323 prontuários para analisar os dados perioperatórios de pacientes submetidos à substituição da articulação do joelho e do quadril. Resultados: A osteoartrite foi a principal indicação para ambos os procedimentos, e os homens mostraram-se mais pesados que as mulheres (p < 0,05). A hipertensão arterial foi a doença prevalente entre os pacientes. A perda sanguínea foi mais frequente na cirurgia do joelho do que na do quadril. Conclusões: O perfil dos pacientes submetidos à artroplastia melhorou substancialmente nos últimos dez anos, associando a diminuição do período de internação com menor risco de eventos tromboembólicos e ausência de infecção, quando comparados com publicações anteriores.

ABSTRACT Objective: To understand the profile of patients undergoing hip and knee replacement during two years, and to compare the data obtained with the literature. Methods: A total of 323 medical records were reviewed to analyze the perioperative data of patients submitted to hip and knee replacement. Results: Osteoarthritis was the main indication for both procedures and male patients were heavier than females (p < 0.05). Hypertension was the prevalent disease among patients. Blood loss was more frequent in knee surgery than in the hip. Conclusions: The profile of patients undergoing total arthroplasty improved substantially over the past decade due to shorter hospital stay, lower risk of thromboembolic events and no infection as compared to previous reports.

OBJETIVO: Comparar os resultados do Índice de Normalização Internacional (INR) obtidos pelo teste rápido com os do método convencional nos pacientes em terapia de anticoagulação oral com varfarina sódica. MÉTODOS: Para 383 pacientes tratados com varfarina (idade média: 56,5 anos; 207 mulheres), o INR foi determinado em sangue capilar pelo equipamento Hemochron Jr. e comparado com os resultados de amostras de plasma venoso analisadas pelo teste convencional realizado em equipamento Coag-A-Mate. Foram avaliados os resultados do desempenho global das amostras e dos seguintes subgrupos: INR < 2,0, entre 2,0 a 3,5 e > 3,5. RESULTADOS: A comparação entre os valores de INR dos dois métodos resultou em um coeficiente de correlação (r) de 0,86. Entretanto, a análise das diferenças médias entre os resultados dos dois testes, considerando os três subgrupos, apresentou diferenças estatisticamente significativas (p < 0,001): 0,14 ± 0,21 (INR < 2,0); 0,54 ± 0,31 (2,0 < INR < 3,5) e 1,64 ± 1,10 (INR> 3,5). O cálculo do teste t-pareado de Student resultou em um p < 0,001 para os três subgrupos analisados. CONCLUSÃO: A adoção do teste rápido para monitoramento da anticoagulação oral apresenta restrições. Esse método subestimou a intensidade da anticoagulação nos três subgrupos estudados.

OBJECTIVE: to compare the international normalized ratio (INR) measured by a point-of-care (POC) testing device with that measured by the conventional method in patients undergoing anticoagulation therapy with warfarin sodium. METHODS: The INR of 383 warfarin-treated patients (mean age: 56.5 years; 207 female) was measured in capillary blood using the Hemochron Jr. device and compared with that of venous plasma samples determined by the conventional method performed in a Coag-A-Mate analyzer. Results were evaluated globally and for the following subgroups: INR < 2.0, from 2.0 to 3.5, and > 3.5. RESULTS: Using both methods, the comparison between INR values yielded a correlation coefficient (r) of 0.86. However, mean differences in INR in both tests, considering the three subgroups, proved to be statistically significant (p <0.001): 0.14 ± 0.21 (INR< 2.0); 0.54 ± 0.31 (2.0 < INR < 3.5), and 1.64 ± 1.10 (INR> 3.5). Paired Student’s t-test analysis revealed a p value < 0.001 for the three subgroups studied. CONCLUSION: The use of point-of-care testing for monitoring oral anticoagulation has some limitations. Anticoagulation intensity was underestimated by this method in the three subgroups studied.
