Precision assessment of a hypertension prevalence survey.

BACKGROUND: Population surveys are crucial for public policy planning and provide valuable representative data. In the health sector studies to identify and assess the prevalence of Arterial Hypertension (AH), a chronic non-communicable disease (NCD), along with its associated risk factors have been conducted. OBJECTIVES: This study aims to assess the effectiveness of a population health survey in estimating the prevalence of arterial hypertension (AH) in the Sorocaba municipality between August 2021 and June 2023. METHODS: The analyzed performance indicator is the precision (design effect - deff) of AH prevalence in adults (≥ 18 years) and their exposure to primary risk factors. The total sample included 1,080 individuals from the urban area, deemed sufficient to estimate a deff of 1.5. This cluster-based study utilized census sectors as clusters, with data collected through household interviews, standardized questionnaires, and measurements of blood pressure and biometric parameters. The deff calculation formula used was weighted variance / raw variance. The Research Ethics Committee approved this study, with registration CAAE 30538520-1-0000-5373. RESULTS: The deff values ranged from 0.44 for chronic obstructive pulmonary disease to 1.63 for asthma, with a deff of 1.00 for AH prevalence. CONCLUSION: The study demonstrated good precision in its results, with high receptivity and cooperation from participants. The cost-effectiveness of the research deemed appropriate. The technique of selecting households within clusters (census sectors) based on detailed mapping and demographic data from the Instituto Brasileiro de Geografia e Estatística (IBGE) proved to be practical and efficient, suitable for replication in other municipalities and for studying other NCDs.

Brazilian Version of the Vestibular Activities and Participation Measure: Cross-Cultural Adaptation, Validity, and Reliability.

BACKGROUND: Vestibular Activities and Participation Measure (VAP) subscales assess the effect of vestibular disorders on activity and participation. This study aimed to perform the cross-cultural adaptation and assess the validity, internal consistency, reliability, and measurement error of the Brazilian version of VAP subscales. METHODS: The cross-cultural adaptation followed the translation, synthesis, back-translation, review by a committee of experts, and pretesting phases. Structural validity was assessed using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), while Spearman's correlation between VAP subscales and the Dizziness Handicap Inventory (DHI) was used to assess construct validity. Cronbach's alpha measured internal consistency. Intraclass correlation coefficient (ICC) assessed intra- and inter-rater reliability, and measurement error was calculated by using the standard error of measurement (SEM) and minimal detectable change (MDC). RESULTS: Additional information was included in the Brazilian version of the Vestibular Activities and Participation measure (VAP-BR) after approval by one of the developers of the instrument to improve the understanding among individuals. One factor was found in the EFA for each subscale with 50% explained variance. Regarding CFA, the subscales 1 (S1) and 2 (S2) presented, respectively, adequate model fit indices (ie, comparative fit index of 0.99 and 0.97, and standardized root mean square residual of 0.04 for both subscales), but a very low factor load in item 6 of S1 (0.08). Chronbach's alpha was 0.80 (S1) and 0.82 (S2). For intra-rater assessment, the S1 and S2 presented an ICC of 0.87 and 0.90, SEM of 0.01 and 1.16, and MDC of 0.39 and 0.46, respectively. When assessed by 2 different raters, SEM values were 1.03 and 1.53, and MDC values were 2.85 and 4.23 for S1 and S2, respectively; both subscales showed an ICC of 0.92. Correlations between DHI and VAP subscales presented coefficients above 0.57. CONCLUSION: The Brazilian version of VAP subscales presents good measurement properties and may assist health professionals in identifying activity limitations and participation restrictions in individuals with vestibular disorders.

Development of a web application to evaluate spirometric curve and clinical variables to support COPD diagnosis in primary care. / Desarrollo de una aplicación web para evaluar los datos de la espirometría y las variables clínicas para apoyar el diagnóstico de EPOC en atención primaria

INTRODUCTION: Choric obstructive pulmonary disease (COPD) is the third mortality cause in the world, and the development of useful diagnostic tools is necessary to improve timely diagnostic rates in primary care settings. OBJECTIVE: To develop a web application displaying spirometric and clinical information - including respiratory symptoms and risk factors- to facilitate a COPD diagnosis. MATERIALS AND METHODS: In this cross-sectional study, an expert consensus was carried out with three specialists using the Delphi method to choose the relevant variables for COPD diagnosis. We developed a Python-based web application to diagnose COPD, displaying the clinical variables deemed relevant by the experts along the spirometric curve. RESULTS: Twenty-six clinical variables were included in the web application for the diagnosis of COPD. A fourth expert used the web application to classify a cohort of 695 patients who had undergone spirometry in a third-level centre and had answered at least one of five questionnaires for COPD screening. Out of the 695 subjects, 34% had COPD, according to the expert that diagnosed them using the web application. Only 42% of the patients in the COPD group had received a previous COPD diagnosis and 19% of the patients in the no COPD group had been misdiagnosed with the disease. CONCLUSION: We developed a web application that displays demographic and clinical information, as well as spirometric data, to facilitate the process of diagnosing COPD in primary care settings.

OBJECTIVES: The aim of this study is to presents an experimental method for surgical guide confection using an intraoral scanner to obtain a 3D model of the patient's complete denture and compare its accuracy with the conventional methodology using computed tomography. STUDY DESIGN: This prospective in-vitro study used 30 polyurethane pre-manufactured mandibles which were divided into two groups, conventional technique (group I) and a new method using intraoral scanner (group II), establishing the virtually planned position of the dental implants as a control group, considered as the gold standard for postoperative comparison. RESULTS: The difference between these methods is close to zero and not statistically significant (p > 0.05), being heigh deviation (Xh) with p:0.130 and angulation difference of dental implants between the groups (Ang) with p:0.396. CONCLUSION: The acquisition of stereolithography image of the prosthesis using an intraoral scanner has a clinically acceptable accuracy, being in agreement with the conventional method.

Data quality review of the Brazilian nosocomial infections surveillance system.

BACKGROUND: Surveillance of healthcare-associated infections (HAIs) is an essential component of hospital infection prevention and control systems. We aimed to assess the quality of the data compiled by the Brazilian HAI Surveillance System from pediatric (PICUs) and neonatal intensive care units (NICUs), between 2012 and 2021. METHODS: Data Quality Review, including adherence, completeness, internal consistency, consistency over time, and consistency of population trend, were computed at both national and state levels based on quality metrics from World Health Organization Toolkit. Incidence rates (or incidence density) of ventilator-associated pneumonia (VAP) and central line-associated bloodstream infection (CLABSI) were obtained from the Brazilian National Nosocomial Infections Surveillance (NNIS) system. Data on sepsis-related mortality, spanning the period from 2012 to 2021, were extracted from the Brazilian National Health Service database (DATASUS). Additionally, correlations between sepsis-related mortality and incidence rates of VAP or CLABSI were calculated. RESULTS: Throughout the majority of the study period, adherence to VAP reporting remained below 75%, exhibiting a positive trend post-2016. Widespread outliers, as well as inconsistencies over time and in population trends, were evident across all 27 states. Only four states maintained consistent adherence levels above 75% for more than 8 years regarding HAI incidence rates. Notably, CLABSI in NICUs boasted the highest reporting adherence among all HAIs, with 148 periods out of 270 (54.8%) exhibiting reporting adherence surpassing 75%. Three states achieved commendable metrics for CLABSI in PICUs, while five states demonstrated favorable results for CLABSI in NICUs. CONCLUSIONS: While adherence to HAI report is improving among Brazilian states, an important room for improvement in the Brazilian NNIS exists. Additional efforts should be made by the Brazilian government to improve the reliability of HAI data, which could serve as valuable guidance for hospital infection prevention and control policies.

[Quality of health information in Mexico in the OECD context: 2017-2021]. / Calidad de la información en salud de México en el contexto de la OCDE: 2017-2021.

OBJECTIVE: To evaluate the health information system (HIS) of Mexico according to the information reported to the Organization for Economic Co-operation and Development (OECD). The ultimate goal is to identify the improvements that should be considered. METHOD: Health indicators published by the OECD (2017 to 2021) are analyzed according to 11 thematic groups. Coverage (quantity and type of indicators reported by thematic group) and quality of information were assessed, according to OECD guidelines. RESULTS: Mexico reported annually 14 of 378 indicators (3.7%), and discontinuously 204. In no group were all indicators reported annually, except for the two on COVID-19. Three out of 88 were reported annually on use of services; and none on health status, quality of care and pharmaceutical market. Twelve indicators (5.5% of those reported by Mexico, 3.2% of the full OECD set) had optimal quality and annual reporting. 57.7% of the reported indicators had at least one quality defect. CONCLUSIONS: Within the framework of the standards set by the OECD, of which Mexico is a member, the Mexican HIS presents significant deficits in coverage and quality of information. These results should be considered to implement improvement initiatives.

Diagnostic accuracy of non-contrast MRI in frozen shoulder.

INTRODUCTION: Despite being the most used exam today, few studies have evaluated the accuracy of findings on non-contrast magnetic resonance imaging (MRI). The primary objective of the study was to evaluate the sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of non-contrast MRI findings in frozen shoulder, isolated and in combination. The secondary objectives were to define the interobserver and intraobserver agreement of the assessments and the odds ratio for frozen shoulder because of the various findings of MRI. METHODS: A retrospective diagnostic accuracy study comparing non-contrast MRI findings between the frozen shoulder group and the control group. Sensitivity, specificity, positive and negative predictive value, accuracy, odds ratio, interobserver and intraobserver agreement were calculated for each finding and their possible associations. RESULTS: The hyperintensity on capsule in the axillary recess presented 84% sensitivity, 94% specificity, and 89% accuracy. The obliteration of the subcoracoid fat triangle in the rotator interval had sensitivity 34%, specificity 82% and accuracy 58%. For coracohumeral ligament thickness ≥ 2 mm had specificity 66%, 48% specificity and 57% accuracy. Capsule thickness in the axillary recess ≥ 4 mm resulted in 54% sensitivity, 82% specificity, and 68% accuracy. Regarding interobserver agreement, only the posteroinferior and posterosuperior quadrants showed moderate results, and all the others showed strong reliability. The odds ratio for hyperintensity in the axillary recess was 82.3 for frozen shoulder. The association of these findings increased specificity (95%). CONCLUSION: The accuracy of non-contrast magnetic resonance imaging is high for diagnosing frozen shoulder, especially when evaluating the hyperintensity of the axillary recess. The exam has high reliability and reproducibility. The presence of an association of signs increases the specificity of the test. LEVEL OF EVIDENCE: Level III, study of diagnostic test.

Evaluating the precision and accuracy of digital dental models with a low-cost structured light device

ABSTRACT Objective: This study evaluated the accuracy and precision of digital models acquisition using a home-built, low-cost scanning system based on the structured light method. Methods: a plaster model (PM) was scanned using the experimental device (SL) and a dental desktop scanner (DS). The teeth dimensions of PM and SL models were measured in triplicate, with a caliper and digitally, respectively. The agreement of the measurements of each model was evaluated using the intraclass correlation coefficient, and the validity between the different measurement techniques was assessed using the Bland-Altman analysis. The accuracy and precision of the models were qualitatively investigated using the mesh superposition of the SL and DS models. Results: A high intraclass correlation coefficient was observed in all models (PM=0.964; SL1=0.998; SL2=0.995; SL3=0.998), and there was no statistical difference between the measurements of the SL models (p>0.05). PM and SL model measurements were found to be in good agreement, with only 3.57% of the observed differences between the same measurement being located outside 95% limits of agreement according to Bland and Altman (0.43 and -0.40 mm). In the superimpositions of SL-SL and SL-DS models, areas of discrepancy greater than 0.5 mm were observed mainly in interproximal, occlusal, and cervical sites. Conclusion: These results indicate that the home-built SL scanning system did not possess sufficient accuracy and precision for many clinical applications. However, the consistency in preserving the dental proportions suggests that the equipment can be used for planning, storage, and simple clinical purposes.

RESUMO Objetivo: Este estudo avaliou a acurácia e a precisão da aquisição de modelos digitais utilizando um sistema de digitalização caseiro e de baixo custo baseado no método de luz estruturada. Material e Métodos: Para isso, um modelo de gesso (MG) foi digitalizado utilizando o dispositivo experimental (LE) e um scanner dental de mesa (SD). As dimensões dos dentes dos modelos MG e LE foram medidas em triplicata com um paquímetro e digitalmente, respectivamente. A concordância das medidas de cada modelo foi avaliada usando o coeficiente de correlação intraclasse, e a validade entre as diferentes técnicas de medição foi avaliada usando a análise de Bland-Altman. A acurácia e a precisão dos modelos foram investigadas qualitativamente usando a sobreposição de malhas dos modelos LE e SD. Resultados: Um alto coeficiente de correlação intraclasse foi observado em todos os modelos (MG=0,964; LE1=0,998; LE2=0,995; LE3=0,998) e não houve diferença estatística entre as medições dos modelos LE (p>0,05). As medições dos modelos MG e LE mostraram boa concordância, com apenas 3,57% das diferenças observadas entre as mesmas medições localizadas fora dos limites de concordância de 95% de acordo com a análise de Bland-Altman (0,43 e -0,40 mm). Nas sobreposições dos modelos LE-LE e LE-SD, foram observadas áreas de discrepância maiores que 0,5 mm principalmente nos sítios interproximais, oclusais e cervicais. Conclusões: Esses resultados indicam que o sistema de digitalização por luz estruturada caseiro não possui precisão e acurácia suficientes para muitas aplicações clínicas. No entanto, a consistência na preservação das proporções dentárias sugere que o equipamento pode ser usado para planejamento, armazenamento e propósitos clínicos simples.

Influence of repositioning guides' color and usage on precision in tooth color measurement with a clinical spectrophotometer

Abstract Repositioning guides are commonly employed in clinical studies to ensure consistent tooth color measurements. Yet, their influence on measured color remains uncertain. Objective This study evaluated the impact of repositioning guides' color and usage on tooth color measurement using a clinical spectrophotometer. Methodology In total, 18 volunteers participated in this study, in which the color of their upper left central incisor and upper left canine was measured with or without repositioning guides (control). The guides were made from pink, blue, or translucent silicone, as well as an acetate-based bleaching tray. Tooth color was measured in triplicates using a clinical spectrophotometer based on the CIELAB system. The standard deviations of these readings were used to estimate reproducibility, and color differences (ΔE00) between the measurements with guides and the control were calculated. Results Repositioning guides had a minimal effect on L* values and no effect on b* values. The use of pink silicone increased a* values, whereas blue or translucent silicone reduced them. Irrespective of the evaluated tooth, the lowest ΔE00 values were observed for the translucent silicone and bleaching tray. The usage of guides only affected data variability for the L* color coordinate. Conclusion Using repositioning guides can significantly impact the precision of tooth color measurement with a clinical spectrophotometer.

Qualidade de dados antropométricos de crianças menores de 5 anos no Sistema de Vigilância Alimentar e Nutricional, 2008-2020 / Quality of anthropometric data of children under 5 years in the Brazilian National Food and Nutrition Surveillance System, 2008-2020 / Calidad de datos antropométricos de niños menores de 5 años en el Sistema de Vigilancia Alimentaria y Nutricional, 2008-2020

O planejamento, o monitoramento e a avaliação das ações de alimentação e nutrição dependem de estimativas confiáveis realizadas a partir de dados antropométricos de qualidade adequada. O objetivo deste estudo foi analisar a qualidade de dados antropométricos de crianças menores de 5 anos no Sistema de Vigilância Alimentar e Nutricional (SISVAN) no período de 2008 a 2020. A amostra compreendeu 23.453.620 crianças menores de 5 anos. Inicialmente, avaliamos a distribuição de valores faltantes e de valores fora do espectro do equipamento e calculamos o índice de preferência de dígito para peso e altura. Os índices nutricionais altura para idade (A-I), peso para idade (P-I) e índice de massa corporal para idade (IMC-I) foram calculados com a utilização do padrão de crescimento da Organização Mundial da Saúde, de 2006. Em seguida, sinalizamos os valores biologicamente implausíveis (VBI) e calculamos o desvio padrão (DP) dos índices nutricionais. Para cada município, calculamos a média e o DP de A-I e P-I e plotamos os valores de DP em função da média. Em todas as Unidades Federativas, o índice de preferência de dígito alcançou valor mínimo de 80 para altura e 20 para peso. Para os três índices nutricionais, houve redução da frequência de VBI no período de 2008 a 2020. Mesmo após a exclusão dos VBI, identificamos elevada variabilidade para os três índices nutricionais. Os indicadores avaliados demonstraram baixa qualidade da mensuração principalmente nas regiões Norte e Nordeste. Nossos resultados indicam qualidade insuficiente dos dados antropométricos em crianças menores de 5 anos e reforçam a necessidade de investimento em ações para o aprimoramento da coleta e do registro das informações antropométricas.

The planning, monitoring, and evaluation of food and nutrition actions depend on reliable estimates based on adequate anthropometric data. The study aimed to analyze the quality of anthropometric data of children aged under 5 years in the Brazilian National Food and Nutrition Surveillance System (SISVAN) from 2008 to 2020. The sample comprised 23,453,620 children aged under 5 years. Initially, we evaluated the distribution of missing values and values outside the spectrum of the instrument, and calculated the digit preference index for weight and height. The nutritional indexes height for age (HAZ), weight for age (WAZ), and body mass index for age (BAZ) were calculated according to the World Health Organization 2006 child growth standards. Then, we identified the biologically implausible values (BIV) and calculated the standard deviation (SD) of the nutritional indexes. For each municipality, we calculated the mean and SD of HAZ and WAZ; and plotted the SD values as a function of the mean. In all Federative Units, the digit preference index reached a minimum value of 80 for height and 20 for weight. For the three nutritional indexes, there was a reduction in the frequency of BIV in the 2008-2020 period. Even after the exclusion of BIV, we identified high variability for the three nutritional indexes. The indicators evaluated showed low quality of measurement, especially in the North and Northeast regions. Our results indicate insufficient quality of anthropometric data in children aged under 5 years, and reinforce the need to invest in actions to improve the collection and recording of anthropometric information.

Para cada municipio, calculamos la media y la DE de A-E y P-E; y representamos los valores de DE en función de la media. En todas las Unidades Federativas, el índice de preferencia de dígito alcanzó el valor mínimo de 80 para altura y 20 para peso. Para los tres índices nutricionales, hubo una disminución de la frecuencia de VBI entre los años de 2008 y 2020. Incluso tras excluir los VBI, identificamos una alta variabilidad para los tres índices nutricionales. Los indicadores evaluados demostraron una baja calidad de medición, sobre todo en las regiones Norte y Nordeste. Nuestros resultados indican una calidad insuficiente de datos antropométricos en niños menores de 5 años y fortalecen la necesidad de inversión en acciones para mejorar la recolección y registro de las informaciones antropométricas.

IRT/IRT as a newborn cystic fibrosis screening method: optimal cutoff points for a mixed population / Protocolo TIR/TIR como método de triagem neonatal para fibrose cística: pontos de corte ideais para populações com baixa incidência da doença e poucos recursos / Protocolo TIR/TIR como método de tamizaje neonatal de fibrosis quística: puntos de corte ideales para poblaciones con baja incidencia de la enfermedad y pocos recursos

Abstract: The Brazilian Unified National Health System (SUS) has incorporated newborn screening for cystic fibrosis since 2001. The protocol involves two samples of immunoreactive trypsinogen (IRT1/IRT2). This study aims to analyze fixed and floating values at the first and second IRT (IRT1/IRT2) cutoff points and assess the accuracy of the IRT/IRT methodology in a population from Northeastern Brazil. Descriptive, individual-level data from the newborn screening reference service data system (2013-2017) were used in this observational population study. The sensitivity, specificity, and positive predictive values (PPV) for the protocol were calculated. The best cutoff point was determined using the Youden's index. The previous year's cut-off values for the IRT1 and IRT2 99.4-, 99.5-, 99.6-, and 99.7-percentiles were utilized for the floating cutoff. During the studied period, 840,832 newborns underwent screening for cystic fibrosis, obtaining 49 cystic fibrosis diagnoses: 39 by newborn screening (79.6%) and 10 (20.4%) by clinical suspicion (false negative). The sensitivity, specificity, and PPV of the protocol totaled 79.6%, 99.9%, and 6.1%, respectively. No proposed cutoff for IRT1 performed better than the current one. IRT2 performed similarly to the current protocol at a cutoff point of 90ng/mL, showing the appropriate sensitivity and specificity while reducing the frequency of false positives. The protocol to screen newborns for cystic fibrosis had low sensitivity, a predictive positive value, and a high number of false positives and negatives. A floating cut point for IRT1 or IRT2 seems to constitute no viable option. However, changing the IRT2 cut point from 70ng/mL to 90ng/mL seems to have advantages and should undergo consideration.

Resumo: A triagem neonatal para fibrose cística oi incorporada ao Sistema Único de Saúde (SUS) em 2001. O protocolo envolve duas amostras de tripsinogênio imunorreativo (TIR/TIR). O objetivo foi analisar os valores fixos e flutuantes no primeiro e segundo pontos de corte da TIR (TIR1/TIR2) e avaliar a acurácia da metodologia TIR/TIR em uma população do nordeste brasileiro. Trata-se de um estudo observacional de base populacional que inclui dados descritivos em nível individual obtidos retrospectivamente do Serviço de Referência em Triagem Neonatal (2013-2017). Foram calculados a sensibilidade, a especificidade e o valor preditivo positivo (VPP) do protocolo. O melhor ponto de corte foi determinado pelo índice de Youden. Os pontos de corte do ano anterior para os percentis TIR1 e TIR2 de 99,4, 99,5, 99,6 e 99,7 foram utilizados para o ponto de corte flutuante. No período do estudo, 840.832 recém-nascidos foram submetidos à triagem neonatal para fibrose cística, com 49 diagnósticos de fibrose cística, sendo 39 pela triagem neonatal (79,6%) e 10 (20,4%) por suspeita clínica (falso-negativos). A sensibilidade, a especificidade e o VPP do protocolo de triagem neonatal para fibrose cística foram de 79,6%, 99,9% e 6,1%, respectivamente. Nenhum dos pontos de corte propostos para a TIR1 mostrou-se melhor do que o atual. A TIR2 teve desempenho semelhante ao atual no ponto de corte de 90ng/mL, demonstrando sensibilidade e especificidade adequadas, ao mesmo tempo que reduziu a frequência de falsos positivos. A triagem neonatal para fibrose cística apresentou valores baixos de sensibilidade e VPP, e número elevado de falso-positivos e negativos. Um ponto de corte flutuante para TIR1 ou TIR2 não parece ser uma opção viável. No entanto, a mudança do ponto de corte da TIR2 de 70ng/mL para 90ng/mL parece ter vantagens e deve ser considerada.

Resumen: El tamizaje neonatal de fibrosis quística fue incorporado al Sistema Único de Salud (SUS) en el 2001. El protocolo implica dos muestras de tripsinógeno inmunorreactivo (TIR/TIR). El objetivo fue analizar los valores fijos y flotantes en el primer y segundo puntos de corte de la TIR (TIR1/TIR2) y evaluar la precisión de la metodología TIR/TIR en una población del Nordeste brasileño. Se trata de un estudio observacional de base poblacional que incluye datos descriptivos a nivel individual obtenidos retrospectivamente del Servicio de Referencia en Tamizaje Neonatal (2013-2017). Se calcularon la sensibilidad, la especificidad y el valor predictivo positivo (VPP) del protocolo. El mejor punto de corte lo determinó el índice de Youden. Para el punto de corte flotante, se utilizaron los puntos de corte del año anterior para los percentiles TIR1 y TIR2 de 99,4, 99,5, 99,6 y 99,7. Durante el período de estudio, 840.832 recién nacidos fueron sometidos a tamizaje neonatal para fibrosis quística, con 49 diagnósticos de fibrosis quística, 39 de los cuales por la tamizaje neonatal (79,6%) y 10 (20,4%) por sospecha clínica (falsos negativos). La sensibilidad, la especificidad y el VPP del protocolo tamizaje neonatal para fibrosis quística fueron del 79,6%, 99,9% y 6,1%, respectivamente. Ninguno de los puntos de corte propuestos para la TIR1 resultó ser mejor que el actual. La TIR2 tuvo un desempeño similar al actual en el punto de corte de 90ng/mL, lo que demuestra sensibilidad y especificidad adecuadas, a la vez que redujo la frecuencia de falsos positivos. El tamizaje neonatal para fibrosis quística presentó valores bajos de sensibilidad y VPP, y un elevado número de falsos positivos y negativos. Un punto de corte flotante para TIR1 o TIR2 no parece ser una opción viable. Sin embargo, cambiar el punto de corte de la TIR2 de 70ng/mL a 90ng/mL parece tener ventajas y debe tenerse en cuenta.

Floor and ceiling effects on the Montreal Cognitive Assessment in patients with Parkinson's disease in Brazil.

Parkinson's disease (PD) is a common neurodegenerative disease associated with cognitive impairment. The Montreal Cognitive Assessment (MoCA) has been used as a recommended global cognition scale for patients with PD, but there are some concerns about its application, partially due to the floor and ceiling effects. Objective: To explore the floor and ceiling effects on the MoCA in patients with PD in Brazil. Methods: Cross-sectional study with data from patients with PD from five Brazilian Movement Disorders Clinics, excluding individuals with a possible diagnosis of dementia. We analyzed the total score of the MoCA, as well as its seven cognitive domains. The floor and ceiling effects were evaluated for the total MoCA score and domains. Multivariate analyses were performed to detect factors associated with floor and ceiling effects. Results: We evaluated data from 366 patients with PD and approximately 19% of individuals had less than five years of education. For the total MoCA score, there was no floor or ceiling effect. There was a floor effect in the abstraction and delayed memory recall domains in 20% of our sample. The ceiling effect was demonstrated in all domains (80.8% more common in naming and 89% orientation), except delayed recall. Education was the main factor associated with the floor and ceiling effects, independent of region, sex, age at evaluation, and disease duration. Conclusion: The floor and ceiling effects are present in specific domains of the MoCA in Brazil, with a strong impact on education. Further adaptations of the MoCA structure for underrepresented populations may reduce these negative effects.

A doença de Parkinson (DP) é uma doença neurodegenerativa comum associada ao declínio cognitivo. A Avaliação Cognitiva de Montreal (Montreal Cognitive Assessment ­ MoCA) tem sido usada como uma escala de cognição global recomendada para pacientes com DP, mas existem algumas preocupações sobre sua aplicação, em parte pelos efeitos solo e teto. Objetivo: Explorar os efeitos solo e teto na MoCA em pacientes com DP no Brasil. Métodos: Estudo transversal com dados de pacientes com DP oriundos de cinco Clínicas de Distúrbios de Movimento no Brasil, excluindo-se pessoas com possível diagnóstico de demência. Nós analisamos a pontuação total da MoCA, assim como a de seus sete domínios cognitivos. Os efeitos solo e teto foram avaliados para a pontuação total da MoCA e seus domínios. Foram feitas análises multivariadas para a detecção de fatores associados os efeitos solo e teto. Resultados: Nós avaliamos dados de 366 pacientes com DP, e aproximadamente 19% das pessoas tinham menos que cinco anos de escolaridade. Para a pontuação total do MoCA, não houve efeito solo ou teto. Houve efeito solo nos domínios abstração e memória de evocação tardia em 20% de nossa amostra. O efeito teto foi demonstrado em todos os domínios (80,8% mais comum em nomeação e 89% orientação), com exceção de memória de evocação tardia. A educação foi o principal fator associado aos efeitos solo e teto, independentemente de região, sexo, idade na avaliação e duração da doença. Conclusão: Os efeitos solo e teto estão presentes em domínios específicos da MoCA no Brasil, com forte impacto da educação. Adaptações adicionais à estrutura da MoCA para populações vulneráveis podem reduzir esses efeitos negativos.

Aseguramiento y control de la calidad de los datos en un estudio de cohorte en Colombia

Introducción: La calidad de los datos facilita garantizar la fiabilidad de los estudios observacionales. Objetivo: Describir el aseguramiento y el control de calidad para mantener la fiabilidad y la validez del dato en un estudio de cohorte. Métodos: Presentar el manejo de datos implementado dentro de un seguimiento de enfermos renales crónicos cuya exposición fue un programa de protección renal comparado con el tratamiento convencional y su asociación con desenlaces clínicos. Se evaluó el cambio en la frecuencia de errores después de implementar el plan y la reproducibilidad del ingreso de registros a las bases de datos. Resultados: Se documentó una disminución progresiva en los errores cometidos en la captación de datos. El valor de Kappa entre los recolectores de la información para las variables clínicas más importantes fue 0,960 para la depuración de creatinina 150 mg/dL; 0,730 para la alteración del sedimento urinario; 0,956 para la asignación de estadio al ingreso. Los coeficientes de correlación intraclase para la identificación de las cifras de presión arterial sistólica fue 0,996; para la de presión arterial diastólica 0,993 y para los niveles de creatinina sérica al diagnóstico 0,995. Discusión: La calidad de los datos comienza con el reconocimiento de los retos y dificultades que implica su responsable captación, de ahí el aporte de la estandarización de los procesos y el personal que los lleve a cabo en forma idónea. Estudios evidencian que muchos procesos de mejora surgen en el desarrollo de la investigación sin protocolos preestablecidos. Conclusión: La reducción en la proporción y el tipo de error durante el proceso de captación de datos se debe a su identificación temprana y la corrección de instructivos, del instrumento de control de diligenciamiento y de la capacitación continua del personal. El análisis mostró una buena concordancia interevaluador.

Introduction: Data quality makes it easier to ensure that observational studies are reliable. Objective: To describe assurance and quality control to maintain data reliability and validity in a cohort study. Methodology: We present the data management strategies implemented in a study that followed patients of chronic kidney disease who were in a renal protection program and compared them with those undergoing conventional treatment to observe its association with clinical outcomes. We assessed the changes in error frequency after implementing the plan along with the reproducibility of the strategies for entering records into the databases. Results: We documented a progressive decrease of data collection errors. The Kappa values among data collectors for the most important variables were: 0.960 for creatinine clearance 150 mg/dl; 0.730 for urinary sediment alteration and 0.956 for stage allocation upon admission. The intraclass correlation coefficient for the identification of systolic blood pressure was 0.996; for diastolic blood pressure, the coefficient was 0.993 and for serum creatinine levels at diagnosis, the value was 0.995. Discussion: Data quality begins with the recognition of the challenges and difficulties involved in responsible data collection, hence the contribution of standardized processes and personnel to carry them out in a suitable manner. Studies show that many improvement processes arise in the development of research without pre-established protocols. Conclusion: The reduction in error ratio and type during the data collection process are the result of the early identification of erroneously entered or missing data, the correction of the guidelines for completing forms as well as of the instruments for detecting errors and continuous training of the staff. The analysis showed good inter-rater reliability.

Comparação da percepção da família e do fisioterapeuta utilizando o sistema GMFCS e o Questionário de Relato Familiar / Perception comparation of the family and physical therapist using the GMFCS system and the Family Report Questionnaire

A Paralisia Cerebral (PC) é uma patologia amplamente conhecida e estudada entre os profissionais de saúde. No meio acadêmico, possui algumas classificações importantes que auxiliam a comunicação entre a equipe multiprofissional. O Sistema de Classificação da Função Motora Grossa (Gross Motor Function Classification System -GMFCS) classifica a função motora grossa do indivíduo segundo a habilidade do movimento autoiniciado, sendo dividido em cinco níveis. O domínio sobre a classificação e nível motor da criança devem ser de responsabilidade da equipe multiprofissional bem como o conhecimento por parte dos pais e ou responsáveis. Esse saber, muitas vezes pode estar limitado, e com isso a relação entre os profissionais de saúde, família e paciente pode entrar em conflito, gerando dúvidas. Objetivo: Este estudo tem por finalidade quantificar a concordância entre o conhecimento dos pais e/ou responsáveis sobre a classificação da função motora grossa quando comparados à classificação dada pelos fisioterapeutas e médicos, assim como, quantificar o quanto destes pais e/ou responsáveis já tinham um conhecimento prévio da classificação. Método: Trata-se de um estudo prospectivo observacional, com 96 pacientes, aos quais foram analisados em prontuário eletrônico. Sendo aplicado, então, o Questionário de Relato Familiar (GMFCS Family Report Questionnaire).Resultados: Em todas as variáveis dependentes avaliadas demonstrou-se uma taxa de concordância acima dos 60%; o valor de Kappa apresentado foi de k= >0,7, havendo, portanto, uma confiabilidade entre grupos de moderada a forte. Conclusão: Em geral, os profissionais de saúde se apresentam mais suscetíveis a classificarem os pacientes em níveis funcionais melhores do que quando comparados aos pais/responsáveis.

Cerebral Palsy (CP) is a widely studied and known pathology between the health professionals and carries with it, in the academic environment, some important classifications that help the communication between professionals in a multidisciplinary team. The Gross Motor Function Classification System (GMFCS) purpose is to classify the gross motor in the child based on the self-initiated movement ability, being divided in five levels. Just like the multidisciplinary team needs to be aware of this classification and the child level, the parents and/or caregivers also need to know about it and agree on it. This understanding can often be limited, and with that, the relationship between the health professionals and the family can conflict, presenting problems in the future. Objective: This study has the purpose to quantify agreement between the parents and/or caregivers about the classification of the gross motor function when compared with the classification given by the physiotherapy and physiatrist, as well as quantify how much the parents and/or caregivers knew about the previous classification.Method:It is a prospective observational study, done with 96 patients, in which the electronic medical records were analyzed and tabulated. Being then applied the GMFCS Family Repost Questionnaire. Results:All dependent variables who were evaluated demonstrated a concordance above 60%; the Kappa value present was k= >0.7, having, therefore, a moderate to strong reliability between the groups. Conclusion: In general, thehealth professionals are more susceptible to classify the patients on better functional levels when compared with the family.

[Telehealth, food consumption, and eating behavior in adults: a rapid review of systematic reviewsTelesalud, consumo de alimentos y comportamiento alimentario de la población adulta: examen rápido de revisiones sistemáticas]. / Telessaúde no consumo e comportamento alimentar em adultos: uma revisão rápida de revisões sistemáticas.

Objective: To synthesize the evidence about the effects of telehealth interventions provided through smart-phone apps and text messages on the behavior of adults regarding healthy food consumption. Method: A rapid systematic review of the literature was performed through searches in nine electronic databases to identify systematic reviews published in English, Portuguese, and Spanish that evaluated telehealth strategies compared to face-to-face interventions to improve dietary intake in the adult population (18 to 59 years old). Searches were performed in November 2020 and updated in April 2022. The included systematic reviews were assessed for methodological quality using the AMSTAR 2 tool. Results: Five systematic reviews were included. Methodological quality was moderate in one review and critically low in four. There was a dearth of studies comparing the use of telehealth strategies with face-to-face interventions for the promotion of healthy eating in adults. The most consistent results refer to an increase in the consumption of fruits and vegetables with the use of an app or text messages, in addition to improvement in the dietary habits of people with diabetes or glucose intolerance with the use of text messages. Conclusion: Positive effects were observed on healthy eating outcomes for most interventions using mobile apps or text messages; however, the findings refer to a few clinical trials with small samples that were analyzed in the systematic reviews covered in the present rapid review, most of which had low methodological quality. Thus, the current knowledge gap warrants the performance of further methodologically robust studies.

Objetivo: Sintetizar la evidencia sobre los efectos de las intervenciones de telesalud ofrecidas por medio de aplicaciones de telefonía móvil y mensajes de texto en el comportamiento de la población adulta relacionado con una alimentación saludable. Métodos: Se realizó un examen rápido mediante búsquedas en nueve bases bibliográficas electrónicas para localizar revisiones sistemáticas publicadas en español, inglés y portugués en las que se evaluaran estrategias de telesalud en comparación con atención presencial para mejorar la alimentación de la población adulta (de 18 a 59 años). Las búsquedas se realizaron en noviembre del 2020 y se actualizaron en abril del 2022. La calidad metodológica de las revisiones sistemáticas incluidas se evaluó con la herramienta AMSTAR 2. Resultados: Se incluyeron cinco revisiones sistemáticas, una con un grado de confianza moderado y las otras con un grado de confianza sumamente bajo. Se comprobó una falta de estudios en los que se compararan el uso de estrategias de telesalud con la atención presencial para promover la alimentación saludable de la población adulta. Los resultados más coherentes se refieren al aumento del consumo de frutas y verduras con el uso de aplicaciones móviles o de mensajes de texto, así como a la mejora del patrón alimentario de las personas con diabetes o con intolerancia a la glucosa con el uso de mensajes de texto. Conclusión: La mayoría de los análisis de las intervenciones en las que se emplearon aplicaciones de telefonía móvil o mensajes de texto mostraron efectos positivos en los resultados relativos a una alimentación saludable. Sin embargo, estos hallazgos se refieren a unos pocos ensayos clínicos con pequeñas muestras de participantes incluidos en las revisiones sistemáticas del presente examen rápido, en su mayoría de baja calidad metodológica. En conclusión, existe una laguna en los conocimientos y es importante realizar estudios con una metodología más sólida.

Relative validity and reproducibility of WHO indicators for assessment of feeding practices in children under two years of age / Validade relativa e reprodutibilidade de indicadores da OMS para avaliação da alimentação de crianças menores de dois anos

Abstract The study aimed to evaluate relative validity and reproducibility of seven WHO indicators of dietary practices in children aged 6-23.9 months. Data from probabilistic sample of children who used primary healthcare services in Rio de Janeiro, Brazil were collected using a 24h dietary recall (24HR) and a closed questionnaire (Q1) on feeding in the day before the study. The last one was reapplied (Q2) around 16 days later. Validity was assessed by comparing the prevalence rates estimated by 24HR and Q1 and calculating the positive (PPV) and negative (NPV) predictive values, sensitivity (Se), specificity (Sp), and accuracy index (AI) for the resulting indicators. For reproducibility, estimated prevalence rates based on Q1 and Q2 were compared and the kappa index and prevalence-adjusted bias-adjusted kappa were estimated. Of the seven estimated indicators, the prevalence of two was overestimated (Continued breastfeeding: 50.0% vs 40.0%; Sweet beverage consumption: 65.1% vs 52.7%) and the prevalence of one was underestimated (Zero vegetable or fruit consumption: 6.5% vs 18.1%). For most indicators, Se and PPV were higher than Sp and NPV. The prevalence rates determined with Q1 and Q2 were similar for 6 indicators. More than half showed good, very good or excellent agreement.

Resumo O estudo avaliou a validade relativa e a reprodutibilidade de sete indicadores da OMS sobre alimentação de crianças de 6-23,9 meses. Dados de amostra probabilística de usuários de serviços básicos de saúde na cidade do Rio de Janeiro, Brasil, foram coletados por meio de recordatório alimentar de 24 horas (R24h) e questionário fechado (Q1) sobre alimentação no dia anterior ao estudo. Este último foi reaplicado (Q2) em torno de 16 dias depois. A validade foi avaliada comparando-se as prevalências estimadas pelo R24h e Q1 e calculando-se os valores preditivos positivo (VPP) e negativo (VPN), sensibilidade (Se), especificidade (Esp) e índice de acurácia (IA) dos indicadores resultantes. Para reprodutibilidade, as prevalências estimadas com base em Q1 e Q2 foram comparadas e estimados o índice kappa e o kappa ajustado pela prevalência. Dos sete indicadores estimados, houve superestimação da prevalência de dois (aleitamento continuado: 50,0% versus 40,0%; consumo de bebidas adoçadas: 65,1% vs. 52,7%) e subestimação da prevalência de um (não consumo de frutas e hortaliças: 6,5% vs. 18,1%). Para a maioria deles, Se e VPP foram maiores do que Esp e VPN. As prevalências determinadas com Q1 e Q2 foram semelhantes para seis indicadores. Mais da metade dos indicadores apresentaram concordância boa, muito boa ou excelente.

Accuracy of mortality indicators due sepsis-associated deaths in the Federal District / Acurácia dos indicadores de mortalidade devido a sepse dos óbitos ocorridos no Distrito Federal / Precisión de los indicadores de mortalidad por sepsis de las defunciones ocurridas en el Distrito Federal

Background: Sepsis currently represents a challenge for health systems, this fact may be related to the spread of bacterial resistance, the increase in the population of elderly, immunosuppressed individuals, and the improvement of emergency care, favoring the survival of critically ill patients. This article aimed to evaluate the accuracy of mortality indicators due to sepsis in 2018. Method: Validation study of death certificates that occurred in the Federal District in 2018. Declarations whose basic causes of death identified were classified as garbage codes were identified, which were investigated by a multidisciplinary team, capable of reclassifying them with codes that allow for the improvement of health data. In order to assess accuracy, sensitivity, specificity, positive and negative predictive values, positive and negative likelihood ratios of death certificates from sepsis were calculated, with 95% confidence intervals. Results: A total of 6.244 statements were evaluated, of which 233 (3.74%) presented sepsis as the underlying cause before being investigated and only 35 (0.56%) maintained it after the investigation. The filling of statements with sepsis as the underlying cause by physicians showed a sensitivity of 0.9% (95%CI: 0.6 to 1.3) and a specificity of 92.0% (95%CI: 90.9 to 93.1). Conclusion: The low accuracy of the declarations demonstrates the non-reliability of the underlying cause of death from sepsis, especially the completion of death certificates that occurred in the Federal District in 2018.(AU)

Justificativa: A sepse, atualmente, representa um desafio para os sistemas de saúde, tal fato pode estar relacionado com a disseminação da resistência bacteriana, o aumento da população de idosos, os indivíduos imunossuprimidos, e a melhoria do atendimento de emergência, favorecendo a sobrevivência de pacientes críticos. Este artigo teve por objetivo avaliar a acurácia dos indicadores de mortalidade devido à sepse em 2018. Método: Estudo de validação da causa básica dos óbitos ocorridos no Distrito Federal em 2018. Foram identificadas as declarações de óbito cujas causas básicas de morte apontadas foram classificadas como garbage code sepse, as quais foram investigadas por uma equipe multidisciplinar, capacitada para reclassificá-las com códigos que permitem o aprimoramento dos dados em saúde. A fim de avaliar a acurácia, foram calculados os valores de sensibilidade, especificidade, valores preditivos positivo e negativo, razões de verossimilhança positiva e negativa das declarações dos óbitos por sepse, com intervalos de confiança de 95%. Resultados: Um total de 6.244 declarações foram avaliadas, das quais 233 (3,74%) apresentavam a sepse como causa básica antes de serem investigadas e apenas 35 (0,56%) mantiveram-na após a investigação. O preenchimento das declarações com a sepse enquanto causa básica pelos médicos apresentou sensibilidade de 0,9% (IC95%: 0,6 a 1,3) e especificidade de 92,0% (IC95%: 90,9 a 93,1). Conclusão: A baixa acurácia das declarações demonstra a não fidedignidade da causa básica de óbito por sepse, sobretudo, do preenchimento das declarações dos óbitos ocorridos no Distrito Federal em 2018.(AU)

Justificación: Sepsis representa en la actualidad un desafío para los sistemas de salud, este hecho puede estar relacionado con propagación de resistencias bacterianas, aumento de la población de ancianos, inmunodeprimidos, y mejora de la atención de urgencias, favoreciendo la supervivencia de los pacientes críticos. Este artículo tuvo como objetivo evaluar la precisión de los indicadores de mortalidad por sepsis en 2018. Método: Estudio de validación de causa básica de muertes ocurridas en Distrito Federal en 2018. Se identificaron actas de defunción cuyas causas básicas de muerte fueron clasificadas como sepsis código basura y fueron investigadas por un equipo multidisciplinario capacitado para reclasificarlas con códigos que permitan la mejora de datos de salud. Para evaluar la precisión, se calcularon sensibilidad, especificidad, valores predictivos positivo y negativo y razones de verosimilitud positiva y negativa de certificados de defunción por sepsis, con intervalos de confianza del 95%. Resultados: se evaluaron 6.244 declaraciones, de las cuales 233 (3,74%) tenían como causa básica la sepsis antes de ser investigadas y solo 35 (0,56%) mantuvieron después de investigación. Realización de declaraciones con sepsis como causa subyacente por parte de los médicos mostró sensibilidad del 0,9% (95%IC: 0,6 a 1,3) y especificidad del 92,0% (95%IC: 90,9 a 93,1). Conclusión: Baja precisión de las declaraciones demuestra la poca confiabilidad de la causa subyacente de muerte por sepsis, especialmente la finalización de los certificados de defunción ocurridos en Distrito Federal en 2018.(AU)
