SUMMARY OBJECTIVE: The aim of this study was to measure the reliability, internal consistency, and construct validity of the Kidney Symptom Questionnaire for the Brazilian population. METHODS: This is a cross-cultural adaptation and questionnaire validation study. We included native Brazilians of both sex aged>18 years, as well as hypertensive and/or diabetic patients. All participants were assessed using Screening for Occult Renal Disease, EuroQol 5 Dimensions, 36-Item Short Form Survey, and the Kidney Symptom Questionnaire. We used Spearman’s coefficient (rho) to measure the correlations between the Kidney Symptom Questionnaire and other instruments; Cronbach’s alpha to measure internal consistency; and intraclass correlation coefficient, standard error of measurement, and minimum detectable change to measure test-retest reliability. RESULTS: The sample was formed by 121 adult participants, mostly female, with systemic arterial hypertension and/or diabetes mellitus. We found excellent reliability (intraclass correlation coefficient≥0.978), adequate internal consistency (Cronbach’s alpha≥0.860), and adequate construct validity on the Kidney Symptom Questionnaire domains; besides, we observed significant correlations between the Kidney Symptom Questionnaire and other instruments. CONCLUSION: The Brazilian version of the Kidney Symptom Questionnaire has adequate measurement properties to assess chronic/occult kidney disease in patients who do not require renal replacement therapy.

SUMMARY OBJECTIVE: This study aimed to translate, cross-culturally adapt, and validate the Heart Disease Fact Questionnaire into Brazilian Portuguese. METHODS: The Brazilian version of the Heart Disease Fact Questionnaire was developed through the processes of translation, back-translation, review committee, and pre-test. Test-retest reliability was measured using the intraclass correlation coefficient and the kappa coefficient. Internal consistency was measured using Cronbach's alpha. For construct validity, the total Heart Disease Fact Questionnaire score was correlated with the Diabetes Knowledge Scale and the Diabetes Attitudes Questionnaire. Ceiling and floor effects were also evaluated in this study. RESULTS: For construct validity and floor and ceiling effect measurements, a total of 100 participants were selected. Reliability was measured using a sub-sample of 30 participants from the total sample. We identified adequate values of reliability (kappa between 0.22 and 1.00 and ICC=0.75) and internal consistency (Cronbach's alpha=0.79). We observed adequate correlations of the Heart Disease Fact Questionnaire score with Diabetes Knowledge Scale (r=0.348) and Diabetes Attitudes Questionnaire (r=0.136). No ceiling or floor effects found. CONCLUSION: Brazilian Portuguese version of the Heart Disease Fact Questionnaire has adequate psychometric properties according to the best scientific recommendations.

SUMMARY BACKGROUND: Coronavirus disease 2019, which is caused by the new severe acute respiratory syndrome coronavirus 2, became a pandemic in 2020 with a mortality rate of 2% and high transmissibility, thus making studies with an epidemiological profile essential. OBJECTIVES: The aim of this study was to characterize the population that performed the severe acute respiratory syndrome coronavirus 2 molecular and serological tests in Carlos Chagas Laboratory – Sabin Group in Cuiabá. METHODS: A retrospective cross-sectional study was carried out with all the samples collected from nasal swab tested by RT-PCR and serological for severe acute respiratory syndrome coronavirus 2 IgM/IgG from the population served between April and December 2020. FINDINGS: In the analysis period, 23,631 PCR-coronavirus disease 2019 examinations were registered. Of this total number of cases, 7,649 (32.37%) tested positive, while 15,982 (66.31%) did not detect viral RNA and 374 of the results as undetermined. The peak of positive RT-PCR performed in July (n=5,878), with 35.65% (n=2,096). A total of 8,884 tests were performed on serological test SOROVID-19, with a peak of 1,169 (57.16%) of the positive tests for severe acute respiratory syndrome coronavirus 2 in July. MAIN CONCLUSIONS: Molecular positivity and serological tests, both peaked in July 2020, were mostly present in women aged 20–59 years, characterizing Cuiabá as the epicenter of the Midwest region in this period due to the high rate of transmissibility of severe acute respiratory syndrome coronavirus 2.

RESUMO A artroplastia total de quadril, procedimento cirúrgico ortopédico realizado frequentemente pelo desgaste da articulação do quadril, pode ocasionar algias, incapacidades, distúrbios proprioceptivos, déficit no equilíbrio e na força muscular. Deste modo foi realizado um estudo de revisão sistemática com o objetivo de verificar se os pacientes submetidos a cirurgia de artroplastia total de quadril possuem alteração de força muscular e equilíbrio. Foram realizadas buscas nas seguintes bases de dados: Lilacs, Pedro e Pubmed, como também na biblioteca online Scielo e no portal da CAPES no período de agosto de 2017 a junho de 2018. Foram incluídos estudos realizados em população acima de 18 anos de ambos os sexos que passaram pela cirurgia de artroplastia total de quadril. A busca forneceu inicialmente 595 artigos, dos quais 15 foram selecionados para leitura completa, sendo destes apenas sete foram incluídos. Os estudos evidenciaram alterações de diminuição da força muscular e déficit no equilíbrio resultando na piora da capacidade funcional do indivíduo. Dessa forma, conclui-se que os pacientes que foram submetidos a cirurgia de artroplastia total de quadril possuem alterações no equilíbrio e principalmente na força muscular periférica. No entanto, devido à escassez de estudos relacionados ao tema, tornam-se necessárias novas pesquisas.

ABSTRACT Total hip arthroplasty, an orthopedic surgical procedure often performed by hip joint wear, can lead to pain, disability, proprioceptive disorders, a deficit in balance, and muscle strength. Thus, a systematic review study was carried out to verify if patients undergoing total hip arthroplasty had altered muscle strength and balance. Searches were carried out in the following databases: Lilacs, Pedro, and Pubmed, as well as in the online Scielo library and the CAPES portal from August 2017 to June 2018. Studies carried out on a population over 18 years of age who underwent total hip arthroplasty surgery. The search initially provided 595 articles, of which 15 were selected for complete reading, of which only seven were included. The studies evidenced alterations of decrease of muscular strength and deficits in the balance, resulting in worsening of the individual's functional capacity. Thus, it is concluded that patients who underwent total hip arthroplasty surgery have alterations in balance and mainly in peripheral muscle strength. However, due to the scarcity of studies related to the subject, new research is necessary.

ABSTRACT BACKGROUND: Exposure to particulate material produced as a result of increased agricultural activity may increase the number of pneumonia hospitalizations among children. We hope to contribute to the knowledge base through highlighting the environmental mechanisms involved in this outcome and optimizing pollutant control policies. OBJECTIVES: To investigate the association between pneumonia hospitalizations among children and presence of environmental pollutants in a town in the Brazilian Legal Amazon region. DESIGN AND SETTING: Time series study conducted in the town of Tangará da Serra, Mato Grosso (MT), Brazil. METHODS: A total of 158 children aged 0 to 10 years participated in the study. Data on environmental variables and pollutants were extracted daily through the Coupled Chemistry-Aerosol-Tracer Transport model coupled to Brazilian Regional Atmospheric Modeling System (CCATT-BRAMS). Meteorological data were provided by the Weather Forecasting and Climate Studies Center (CPTEC). RESULTS: There was greater frequency of pneumonia hospitalizations in the months of transition between the rainy and dry seasons, with a prevalence ratio 2.4 times higher than in other periods. For environmental pollutants, there was a significant positive correlation between particulate matter (PM2.5) and pneumonia hospitalizations (correlation 0.11), with more admissions on the days when PM2.5 levels were highest (averages of 6.6 µg/m3 when there were no admissions and 13.11 µg/m3 on days with two or more admissions). CONCLUSIONS: The higher the PM2.5 level was, the greater the frequency of hospitalizations also was. Children living in peripheral areas had higher prevalence of pneumonia hospitalizations in the dry period than those who were living in the town center.

OBJETIVO: avaliar a interferência do esmalte de unha na leitura da saturação periférica de oxigênio em pacientes com doença pulmonar obstrutiva crônica, no exercício do degrau. MÉTODOS: foram incluídos pacientes com doença pulmonar obstrutiva crônica estável, não fumantes atuais, de ambos os sexos. Utilizaram-se quatro cores de esmalte (base, rosa claro, vermelho e marrom), distribuídas aleatoriamente entre os dedos da mão direita, tendo os dedos contralaterais como controle. A saturação foi medida em repouso com e sem esmalte e durante o 4º, 5º e 6º minutos do exercício. RESULTADOS: foram incluídos 42 pacientes com idade de 62,9±8,7 anos. No exercício, a cor vermelha diminuiu a mesma no quarto minuto de exercício (p=0,047). A cor marrom reduziu a saturação no repouso e durante o exercício (p=0,01). CONCLUSÃO: em pacientes com doença pulmonar obstrutiva crônica, as cores marrom e vermelha interferem na leitura da saturação periférica de oxigênio no exercício. Este estudo está registrado no Registro Brasileiro de Ensaios Clínicos, sob número de registro: RBR-9vc722.

AIM: To assess the interference of nail polish on the reading of peripheral oxygen saturation in patients with chronic obstructive pulmonary disease on the step exercise. METHODS: In this study, there was the inclusion of patients with chronic obstructive pulmonary disease, current non-smokers, of both sexes. Four different colours of nail polish were used in the present study (base, light pink, red and brown), randomly distributed among the fingers of the right hand, with the corresponding fingers on the opposite hand being controls. Saturation was measured at rest, with and without the polish, and also during the 4th, 5th and 6th minutes of the exercise programme. RESULTS: The experimental universe included 42 patients with ages of 62.9±8.7 years. In the exercise considered, the red colour reduced it in the fourth minute of the exercise (p=0.047). In contrast, the brown colour reduced saturation at rest and also during the course of exercise (p=0.01). CONCLUSION: In patients with chronic obstructive pulmonary disease, the red and brown colours interfered with the reading of the peripheral oxygen saturation during exercise. This study is registered at the Brazilian Register of Clinical Trials (Registro Brasileiro de Ensaios Clínicos) under No. RBR-9vc722.
