ABSTRACT

Objetivo: Investigar a agregação das DCNT e a sua associação com as características sociodemográficas e os aspectos ocupacionais dos trabalhadores da APS. Métodos: Tratou-se de um estudo epidemiológico transversal que analisou os dados parciais de uma coorte retrospectiva realizada em Vitória da Conquista (BA) e em São Geraldo da Piedade (MG) no mês de janeiro de 2022 com 105 trabalhadores da Estratégia Saúde da Família (ESF), que preencheram um questionário eletrônico específico autoaplicável. As variáveis analisadas foram: sociodemográficas, caracterização do trabalho, presença de DCNT e de multimorbidade. Foram aplicados os seguintes procedimentos estatísticos: análise descritiva, análise de cluster, teste de qui-quadrado de Pearson e regressão logística binária. Resultados:As cinco DCNT mais prevalentes foram a rinite/sinusite (30,5%), a cefaleia/enxaqueca (26,7%), o colesterol alto (26,7%), a gastrite (19,0%) e a hipertensão arterial sistêmica (19,0%). A prevalência de multimorbidade foi de 26,7% e foram encontradas 11 combinações de cluster (34,4%), sendo o maior escore na combinação das cinco doenças mais prevalentes. Foi identificada a associação entre a presença de multimorbidade e o sexo, sendo a prevalência 24% menor entre os homens, e com a escolaridade, sendo a prevalência 26% maior nos indivíduos que não possuem ensino superior. Conclusão: Foram identificadas associações entre a presença de multimorbidade e o sexo feminino, e indivíduos que não concluíram o ensino superior. Observou-se, ainda, uma associação simultânea das cinco principais DCNT deste estudo com o nível de escolaridade (AU).


Objectives: Investigate the aggregation of NCDs and their association with sociodemographic characteristics and occupational aspects in primary healthcare workers. Methods: A cross-sectional study analyzed partial data from a cohort profile conducted in Vitória da Conquista (BA) and in São Geraldo da Piedade (MG) in January 2022 with 105 workers of "Estratégia de Saúde da Família (ESF)" who answered a self-report electronic questionnaire. The variables of this research were: sociodemographic characteristics, job aspects, and the presence of NCDs and multimorbidity. Data were analyzed with descriptive statistics, cluster analysis, chi-square test, and binary logistic regression. Results: The five NCDs more prevalent were: rhinitis/sinusitis (30,5%), headache/migraine (26,7%), hypercholesterolemia (26,7%), gastritis (19,0%), and hypertension (19,0%). The prevalence of multimorbidity was 26,7%, and 11 cluster combinations were found (34,4%) since the higher score was identified in the aggregation of the five more prevalent diseases. There was an association between the presence of multimorbidity and the sex (the prevalence is 24% smaller for men) and between the presence of multimorbidity and the level of education (the prevalence is 26% higher in people without a college degree). Conclusion: The prevalence of multimorbidity was associated with the female sex and with people without a college degree. Furthermore, an association was observed between the five more prevalent NCDs in this study and the level of education (AU).

ABSTRACT

Objective: To analyze the trend of epidemiological characteristics and spatiotemporal distribution of pulmonary tuberculosis (PTB) among smear-positive or other types of students in Guizhou Province from 2011 to 2020, and to provide a reference for improving prevention and control measures. Methods: Data were collected from the Chinese Information System's Notifiable Disease and Tuberculosis Management Information System for disease control and prevention, the Joinpoint 4.9.1.0 software was used to analyze the trend of registration rate; the ArcGIS 10.6 software was used to construct a ring map and to perform spatial autocorrelation analysis; the SaTScan 9.7 software was used for spatial-temporal scan statistics. Results: A total of 32 682 student PTB cases were reported in Guizhou Province from 2011 to 2020, including 5 949 (18.20%) smear-positive cases. Most cases occurred from high school students of 16 to 18 years old (43.99%, 14 376/32 682); the annual average registered rate was 36.22/100 000, the highest in 2018 (52.90/100 000), and the registration rate showed an increasing trend. Meanwhile, a similar trend of registration rate was observed among smear-positive or other types of students. The spatialtemporal heterogeneity was found that the "high-high" clustering patterns of smear-positive or other types were aggregated in Bijie City. Six spatialtemporal clusters with statistically significant (all P<0.001) were detected among smear-positive or other cases, respectively. Conclusions: Upward trend with spatial- temporal clusters of PTB cases reported in students from Guizhou Province from 2011 to 2020. Surveillance should be strengthened for high school students, and regular screening should be conducted in high-risk areas to control the source of infection and reduce the risk of transmission.

ABSTRACT

Objective: To analyze the spatial and temporal distribution characteristics of seasonal A(H3N2) influenza [influenza A(H3N2)] in China and to provide a reference for scientific prevention and control. Methods: The influenza A(H3N2) surveillance data in 2014-2019 was derived from China Influenza Surveillance Information System. A line chart described the epidemic trend analyzed and plotted. Spatial autocorrelation analysis was conducted using ArcGIS 10.7, and spatiotemporal scanning analysis was conducted using SaTScan 10.1. Results: A total of 2 603 209 influenza-like case sample specimens were detected from March 31, 2014, to March 31, 2019, and the influenza A(H3N2) positive rate was 5.96%(155 259/2 603 209). The positive rate of influenza A(H3N2) was statistically significant in the north and southern provinces in each surveillance year (all P<0.05). The high incidence seasons of influenza A (H3N2) were in winter in northern provinces and summer or winter in southern provinces. Influenza A (H3N2) clustered in 31 provinces in 2014-2015 and 2016-2017. High-high clusters were distributed in eight provinces, including Beijing, Tianjin, Hebei, Shandong, Shanxi, Henan, Shaanxi, and Ningxia Hui Autonomous Region in 2014-2015, and high-high clusters were distributed in five provinces including Shanxi, Shandong, Henan, Anhui, and Shanghai in 2016-2017. Spatiotemporal scanning analysis from 2014 to 2019 showed that Shandong and its surrounding twelve provinces clustered from November 2016 to February 2017 (RR=3.59, LLR=9 875.74, P<0.001). Conclusion: Influenza A (H3N2) has high incidence seasons with northern provinces in winter and southern provinces in summer or winter and obvious spatial and temporal clustering characteristics in China from 2014-2019.

ABSTRACT

OBJECTIVE@#To analyze the spatial distribution of the prevalence of cognitive dysfunction and its risk factors in Chinese population aged 45 years and above to provide evidence for formulating regional prevention and control strategies.@*METHODS@#The study subjects with complete cognitive function data were selected from the follow-up data of the China Health and Retirement Longitudinal Study (CHARLS) Phase IV. ArcGis 10.4 software was used for spatial analysis of the prevalence of cognitive dysfunction in the population aged 45 years and above for each province based on the geographic information system (GIS) technology.@*RESULTS@#In 2018, the overall prevalence of cognitive dysfunction was 33.59% (5951/17716) in individuals aged 45 and above in China. Global spatial autocorrelation analysis indicated a spatial clustering and a positive autocorrelation (P < 0.001) of the prevalence of cognitive dysfunction in the study subjects, with a Moran's I value of 0.333085. The results of local spatial autocorrelation analysis showed that the southwestern region of China was the main aggregation area of patients with cognitive dysfunction. Geographically weighted regression analysis suggested that a male gender, an advanced age, and illiteracy were the major risk factors for cognitive dysfunction (P < 0.05). These 3 risk factors showed a spatial distribution heterogeneity with greater impact in the northern, western, and northwestern regions of China, respectively.@*CONCLUSION@#The prevalence of cognitive dysfunction is relatively high in individuals aged 45 years and above in China. A male gender, an advanced age, and illiteracy are the major risk factors for cognitive dysfunction and show different spatial distribution patterns, with the northern, western and northwestern regions of China as the key areas for prevention and control, where the prevention and control measures should be designed based on local conditions.

ABSTRACT

At present, the incidence of Parkinson's disease (PD) is gradually increasing. This seriously affects the quality of life of patients, and the burden of diagnosis and treatment is increasing. However, the disease is difficult to intervene in early stage as early monitoring means are limited. Aiming to find an effective biomarker of PD, this work extracted correlation between each pair of electroencephalogram (EEG) channels for each frequency band using weighted symbolic mutual information and k-means clustering. The results showed that State1 of Beta frequency band ( P = 0.034) and State5 of Gamma frequency band ( P = 0.010) could be used to differentiate health controls and off-medication Parkinson's disease patients. These findings indicated that there were significant differences in the resting channel-wise correlation states between PD patients and healthy subjects. However, no significant differences were found between PD-on and PD-off patients, and between PD-on patients and healthy controls. This may provide a clinical diagnosis reference for Parkinson's disease.

ABSTRACT

A gas chromatography-triple quadrupole mass spectrometry(GC-MS) method was established for the simultaneous determination of eleven volatile components in Cinnamomi Oleum and the chemical pattern recognition was utilized to evaluate the quality of essential oil obtained from Cinnamomi Fructus medicinal materials in various habitats. The Cinnamomi Fructus medicinal materials were treated by water distillation, analyzed using GC-MS, and detected by selective ion monitoring(SIM), and the internal standards were used for quantification. The content results of Cinnamomi Oleum from various batches were analyzed by hierarchical clustering analysis(HCA), principal component analysis(PCA), and orthogonal partial least squares-discriminant analysis(OPLS-DA) for the statistic analysis. Eleven components showed good linear relationships within their respective concentration ranges(R~2>0.999 7), with average recoveries of 92.41%-102.1% and RSD of 1.2%-3.2%(n=6). The samples were classified into three categories by HCA and PCA, and 2-nonanone was screened as a marker of variability between batches in combination with OPLS-DA. This method is specific, sensitive, simple, and accurate, and the screened components can be utilized as a basis for the quality control of Cinnamomi Oleum.

ABSTRACT

From 2015 to 2019, the annual average incidence rate of scarlet fever was 7.80/100 000 in Yantai City, which showed an increasing trend since 2017 (χ2trend=233.59, P<0.001). The peak period of this disease was from April to July and November to January of the next year. The ratio of male to female was 1.49∶1, with a higher prevalence among cases aged 3 to 9 years (2 357/2 552, 92.36%). Children in kindergartens, primary and middle school students, and scattered children were the high risk population, with the incidence rate of 159.86/100 000, 25.57/100 000 and 26.77/100 000, respectively. The global spatial auto-correlation analysis showed that the global Moran's I index of the reported incidence rate of scarlet fever in Yantai from 2015 to 2019 was 0.28, 0.29, 0.44, 0.48, and 0.22, respectively (all P values<0.05), suggesting that the incidence rate of scarlet fever in Yantai from 2015 to 2019 was spatial clustering. The local spatial auto-correlation analysis showed that the "high-high" clustering areas were mainly located in Laizhou City, Zhifu District, Haiyang City, Fushan District and Kaifa District, while the "low-high" clustering areas were mainly located in Haiyang City and Fushan District.

ABSTRACT

Objective: to identify spatial clusters of suicide and its epidemiological characteristics in the Chapecó (SC) micro-region from 1996 to 2018. Methods: this was an exploratory ecological study, using data from the Mortality Information System; specific suicide rates and relative risks (RR) were calculated with a 95% confidence interval (95%CI); the scan statistic was used for spatial analysis. Results: there were 1,034 suicides (13.7/100,000 inhabitants), with a male/female ratio of 3.79; the ≥ 60 age group was at higher risk for both sexes; a high risk cluster was found in the southwest region (RR = 1.57) and a low risk cluster in the southeast region, including Chapecó itself (RR = 0.68); risk of suicide among widowed (RR = 3.05; 95%CI 1.99;4.67), separated (RR = 2.48; 95%CI 1.44;4.27), and married (RR = 1.97; 95%CI 1.54;2.51) people was higher than among single people. The main methods were hanging (81.2%) and firearms (9.7%). Conclusion: there was a higher risk of suicide in the elderly, male and widowed people. Hanging was the most frequent method and risk clustering was found in the southwest.

ABSTRACT

RESUMEN La distribución geoespacial de la morbilidad por tuberculosis (TB) pulmonar y extrapulmonar en el municipio de Cúcuta en los años 2019 y 2020 se describió utilizando el método de Kulldorff usando la ubicación geográfica y la fecha de reporte de los casos incidentes de TB. La unidad de análisis fue el evento reportado al Sistema Nacional de Vigilancia Epidemiológica (SIVIGILA). Se identificaron 392 barrios distribuidos en diez comunas, donde se ubicaron 607 casos. En la distribución de la TB pulmonar, la comuna norte fue la que más casos reportó, siendo el barrio El Salado el más afectado de manera repetitiva. Los casos incidentes de TB extrapulmonar no mostraron patrones de repetición en la distribución entre las unidades espaciales y temporales. Se debe priorizar la región occidental dentro de las estrategias de mitigación y control de la propagación de la infección pulmonar del territorio.


ABSTRACT The geospatial distribution of pulmonary and extrapulmonary tuberculosis (TB) morbidity in the municipality of Cúcuta in 2019 and 2020 was described by the Kulldorff method using the geographic location and reporting date of incident TB cases. The unit of analysis was the event reported to the National Epidemiological Surveillance System (SIVIGILA). A total of 607 cases were identified in 392 neighborhoods distributed in ten communes. Most cases of pulmonary TB were reported in the northern commune, with the El Salado neighborhood being the most affected repeatedly. Incident cases of extrapulmonary TB did not show patterns of repetition in the distribution between spatial and temporal units. Strategies to mitigate and control the spread of pulmonary infection should prioritize the western region.

ABSTRACT

The Clificol® COVID-19 Support Project is an innovative international data collection project aimed at tackling some of the core questions in homeopathy, including the notion of Genus Epidemicus. Aims:To shed some light on the notion of Genus Epidemicus in the context of this infection. Going beyond that, the project aims to use these data to tackle more fundamental questions, such as the role of symptoms and rubrics in treatment individualisation. Methodology:This online multi-national data-collection project is supported by the ECH, ECCH, ICH, HRI, LMHI, and other professional associations. The collected data includes demographic information, severity, conventional diagnosis and treatment, presenting symptoms as well as the remedies prescribed. The outcome of treatment was tracked using the ORIDL scale. The concept of Genus Epidemicus, including the role of treatment individualisation, was investigated by analysing whether presenting symptoms cluster into distinct groups (K-Means clustering approach). The symptom data originating from China was obtained using a questionnaire. Results and discussion: 20 Chinese practioners collected 359 cases, primarily in the first half of 2020 (766 consultations, 363 prescriptions). The cluster analysis found two to be the optimum number of clusters. These two symptomatic clusters had a high overlap with the two most commonly prescribed remedies in that population: In cluster 1 there were 297 prescriptions, 95.6% of which were Gelsemium sempervirens, incluster 2, there were 61 prescriptions, 95.1% of which were Bryonia alba. Under the assumption of a single genus epidemicuswe would expect to see a single cluster of symptoms. The data from the Chinese population were not compatible with this assumption. Conclusion:This was the first study that investigated the notion of Genus Epidemicus by using modern statistical techniques. These analyses identified at least two distinct symptom pictures. The notion of a single COVID-19 Genus Epidemicus did not apply to this population.

Foram incluídos somente artigos originais publicados em português ou inglês que identificaram padrão alimentar de adultos saudáveis por meio de abordagem a posteriori, de 2013 a 2018. Os artigos foram selecionados por meio de busca em 4 bases de dados, sendo resgatadas 328 publicações.Resultados:Apenas 9 artigos identificaram padrões alimentares por meio de abordagem a posteriori em adultos, sendo 7 do tipo transversal e 2 longitudinal.O método de abordagem exploratória mais utilizado foi a análise fatorial, abordada em sete estudos. Um artigo utilizou o método de análise de agrupamento, enquanto outros dois utilizaram o método RRR, sendo um deles associado ao método ACP. Conclusões:As metodologias de avaliação do padrão alimentar possuem limitações, o que torna absolutamente importante que os estudos sejam bem delineados, com escolha de inquéritos alimentares mais convenientes, tamanho e seleção da amostra relevantes e testes estatísticos que orientem as decisões do pesquisador da melhor forma possível, para que os resultados retratem padrões e agrupamentos bem fidedignos (AU).


Introduction:There are few studies that have identified dietary patterns in adults without associated pathologies using a posteriori approach methodologies, which represents a large and important field of research in nutritional epidemiology to be explored to better understand the eating habits of different populations in the world and their relationships with other factors. Objective:To analyze the methodologies for identifying dietary patterns in healthy adults who used the a posteriori approach. Methodology:This is an integrative review. Only original articles published in Portuguese or English that identified the dietary pattern of healthy adults through an a posteriori approach, from 2013 to 2018, were included. Results:Only 9 articles identified eating patterns through a posteriori approach in adults, 7 of which were transverse and 2 were longitudinal.The most used exploratory approach method was factor analysis, addressed in seven studies. One article used the cluster analysis method, while two others used the RRR method, one of them associated with the ACP method. Conclusions:The dietary pattern assessment methodologies have limitations, which makes it absolutely important that the studies are well designed, with the choice of more convenient food surveys, relevant sample size and selection, and statistical tests that guide the researcher's decisions in the best possible way, so that the results depict very reliable patterns and groupings (AU).

ABSTRACT

OBJECTIVE@#To study the expression profiles changes of miRNA in apheresis platelets after 1, 3 and 5 days of storage.@*METHODS@#The apheresis platelets were collected from 20 volunteer blood donors. After mixing fully, the platelets were stored in a shaker with (22±2) ℃ horizontal oscillation. The samples were taken on the 1st, 3rd and 5th day, and used to sequence for miRNAs by DNA nanoball (DNB) sequencing technology, which were named as C_1, C_3 and C_5, respectively. The expression level of platelets miRNA was standardized by transcripts per kilobase million (TPM) algorithm. MiRNAs with P-value < 0.001 and the expression difference of more than two times were considered as significant difference between two groups. The expression of miRNAs was verified by real-time fluorescence quantitative PCR (RT-qPCR).@*RESULTS@#By DNB sequencing, there were 688, 730, and 679 platelet miRNAs expressed in C_1, C_3 and C_5 group, respectively. Cluster analysis showed that the expression profile of miRNAs changed significantly. The expression level of the first 20 high abundance miRNAs was about 4/5 of the total amounts of expressed miRNAs in each group, which the top five miRNAs were miR-21-5p, miR-26a-5p, miR-199a-3p, miR-126-3p, and let-7f-5p. The correlation of high abundance platelet miRNAs among the three groups was high (R2=0.876, R2=0.979, R2=0.937, respectively) and the differences were not statistically significant (P>0.05). Compared with the differential expression of platelet miRNAs with more than 1 000 TPM in the C_3 and C_1 group, there were 6 differentially expressed miRNAs, including 3 up-regulated (miR-146a-5p, miR-379-5p, and miR-486-5p) and 3 down-regulated (miR-652-3p, miR-142-5p, and miR-7-5p). While in the C_5 and C_1 group, there were 4 differentially expressed miRNAs, including 2 up-regulated (miR-146a-5p and let-7b-5p) and 2 down-regulated (miR-30d-5p and miR-142-5p). Compared with the differentially expression of platelet miRNAs between 1-1 000 TPM in the C_3 and C_1 group, there were 133 differentially expressed miRNAs, in which 99 were up-regulated and 34 were down-regulated. While in the C_5 and C_1 group, there were 77 differentially expressed miRNAs, in which 31 were up-regulated and 46 were down-regulated. The six selected differentially expressed miRNAs verified by RT-qPCR were consistent with those of sequencing.@*CONCLUSION@#The expression profiles of platelets miRNAs change significantly among 1, 3, and 5 d of storage in vitro.

ABSTRACT

OBJECTIVE@#To propose a new method for mining complexes in dynamic protein network using spatiotemporal convolution neural network.@*METHODS@#The edge strength, node strength and edge existence probability are defined for modeling of the dynamic protein network. Based on the time series information and structure information on the graph, two convolution operators were designed using Hilbert-Huang transform, attention mechanism and residual connection technology to represent and learn the characteristics of the proteins in the network, and the dynamic protein network characteristic map was constructed. Finally, spectral clustering was used to identify the protein complexes.@*RESULTS@#The simulation results on several public biological datasets showed that the F value of the proposed algorithm exceeded 90% on DIP dataset and MIPS dataset. Compared with 4 other recognition algorithms (DPCMNE, GE-CFI, VGAE and NOCD), the proposed algorithm improved the recognition efficiency by 34.5%, 28.7%, 25.4% and 17.6%, respectively.@*CONCLUSION@#The application of deep learning technology can improve the efficiency in analysis of dynamic protein networks.

ABSTRACT

Objective: To understand the spatial characteristics of echinococcosis and associated factors in the pastoral area of Qinghai province, and provide evidence for the effective prevention and control of echinococcosis. Methods: The number of echinococcosis cases in the pastoral areas of Qinghai in 2019 was collected to perform spatial epidemiological analysis. The thematic map of the distribution of echinococcosis cases was generated with software ArcGIS 10.8 for visual analysis and spatial autocorrelation analysis. The spatial autocorrelation and spatial scanning analysis were performed to estimate the clustering of echinococcosis with software SaTScan 9.5. Software GeoDa 1.14 and ArcGIS 10.8 were used to establish spatial lag model and geographical weighted regression model to analyze the related factors of echinococcosis epidemic. Results: In 2019, the echinococcosis surveillance covered 64 741 people in the pastoral area of Qinghai, and 829 echinococcosis cases were found, with a prevalence rate of 1.28%. The distribution of the cases had spatial correlation (Moran's I=0.41, P<0.001). The most possible clustering areas indicated by spatial scanning analysis included Banma, Jiuzhi, Dari and Gande counties of Guoluo Tibetan Autonomous Prefecture (LLR=460.77, RR=9.20, P<0.001). The prevalence of echinococcosis in the pastoral areas was positively associated with the total annual precipitation (β=0.13, P=0.036), and negatively associated with population density (β=-1.36, P=0.019) and doctors/nurse ratio (β=-25.60, P=0.026). Conclusions: The distribution of echinococcosis cases in the pastoral areas of Qinghai in 2019 had spatial correlation, and the prevalence was affected by total annual precipitation, population density, and doctors/nurse ratio.

ABSTRACT

Objective: To analyze the epidemiological characteristics and spatiotemporal clustering of hepatitis A in Zhejiang Province from 2010 to 2019. Methods: The data of hepatitis A incidence in Zhejiang Province from 2010 to 2019 were collected from the infectious disease surveillance system of China Information System for Disease Control and Prevention. ArcGIS 10.7 software was used for spatial autocorrelation analysis. SaTScan 9.6 software was used for spatiotemporal scanning analysis. SPSS 25.0 software was used for additional analysis. Results: Zhejiang Province has reported 5 465 cases of hepatitis A in 2010-2019 years, with an average annual incidence rate of 1.00/100 000, and periodicity and seasonality are not obvious. The incidence of male was higher than that of female (P=0.023), and the highest incidence rate was 50-59 years old. Spatial autocorrelation analysis showed that there was a positive spatial correlation between the incidence of hepatitis A in Zhejiang Province from 2010 to 2017, with the weakest correlation in 2010 (Moran's I =0.103, Z=1.769, P=0.049), and the strongest correlation in 2016 (Moran's I=0.328, Z=4.979, P=0.001). Spatiotemporal scanning analysis showed that there was spatial aggregation of hepatitis A in Zhejiang Province from 2010 to 2019, with a total of three aggregation areas identified. Among them, the mostly aggregation area was concentrated in Xiangshan county of Ningbo city, which covered 10 counties (cities and districts), including Ninghai county and Yinzhou district, and appeared from January 1 to June 30, 2012. Conclusion: The incidence level of hepatitis A in Zhejiang Province shows a stable fluctuation trend from 2010 to 2019, and the seasonal regularity is not obvious. The population group aged 50-59 years old is the key population. There is spatial aggregation in the epidemic situation of hepatitis A. Targeted prevention and control measures of hepatitis A should be done based on the law of spatiotemporal aggregation and local incidence.

ABSTRACT

Our objective is to describe the differences in the sampling plans of the two editions of the Brazilian National Health Survey (PNS 2013 and 2019) and to evaluate how the changes affected the coefficient of variation (CV) and the design effect (Deff) of some estimated indicators. Variables from different parts of the questionnaire were analyzed to cover proportions with different magnitudes. The prevalence of obesity was included in the analysis since anthropometry measurement in the 2019 survey was performed in a subsample. The value of the point estimate, CV, and the Deff were calculated for each indicator, considering the stratification of the primary sampling units, the weighting of the sampling units, and the clustering effect. The CV and the Deff were lower in the 2019 estimates for most indicators. Concerning the questionnaire indicators of all household members, the Deffs were high and reached values greater than 18 for having a health insurance plan. Regarding the indicators of the individual questionnaire, for the prevalence of obesity, the Deff ranged from 2.7 to 4.2, in 2013, and from 2.7 to 10.2, in 2019. The prevalence of hypertension and diabetes per Federative Unit had a higher CV and lower Deff. Expanding the sample size to meet the diverse health objectives and the high Deff are significant challenges for developing probabilistic household-based national survey. New probabilistic sampling strategies should be considered to reduce costs and clustering effects.


Nosso objetivo é descrever as diferenças nos desenhos amostrais das duas edições da Pesquisa Nacional de Saúde (PNS 2013 e 2019) e avaliar como suas mudanças afetaram o coeficiente de variação (CV) e o efeito do desenho (Deff) de alguns dos indicadores avaliados. Variáveis de diferentes partes do questionário foram analisadas para avaliar proporções com diferentes magnitudes. A prevalência de obesidade foi incluída na análise uma vez que a medição de antropometria na pesquisa de 2019 foi realizada em uma subamostra. Os valores do estimador pontual, CV e Deff foram calculados para cada indicador considerando a estratificação das unidades amostrais primárias, a ponderação das unidades amostrais, e o efeito do agrupamento. Para a maioria dos indicadores, CV e Deff foram menores nas estimativas de 2019. Em relação aos indicadores para todos os membros familiares, Deffs foram elevados e atingiram valores superiores a 18 para a posse de um plano de saúde. Quanto aos indicadores no questionário individual, Deff variou de 2,7 a 4,2 em 2013 e de 2,7 a 10,2 em 2019 para a prevalência de obesidade. A prevalência de hipertensão arterial e diabetes por Unidade Federativa apresentou CV maior e Deff menor. A expansão do tamanho da amostra para atender aos diversos objetivos de saúde e Deff altos são desafios expressivos para o desenvolvimento de uma pesquisa nacional domiciliar probabilística. Novas estratégias de amostragem probabilística devem ser consideradas para reduzir custos e efeitos do agrupamento.

Se analizaron variables de diferentes partes del cuestionario para evaluar proporciones con diferentes magnitudes. La prevalencia de obesidad se incluyó en el análisis, ya que la medición de la antropometría en la encuesta de 2019 se realizó en una submuestra. Los valores del estimador puntual, CV y Deff se calcularon para cada indicador considerando la estratificación de las unidades de muestreo primarias, la ponderación de las unidades de muestreo y el efecto de agrupamiento. Para la mayoría de los indicadores, CV y Deff fueron más bajos en las estimaciones de 2019. En cuanto a los indicadores para todos los miembros de la familia, los Deff fueron altos y alcanzaron valores superiores a 18 por tener un plan de salud. En cuanto a los indicadores del cuestionario individual, Deff osciló entre 2,7 y 4,2 en 2013, y entre 2,7 y 10,2 en 2019 para la prevalencia de obesidad. La prevalencia de hipertensión arterial y diabetes por Unidad Federativa tuvo mayor CV y menor Deff. Un mayor tamaño de la muestra para cumplir con los diversos objetivos de salud y un alto valor de Deff son desafíos importantes para el desarrollo de una encuesta nacional domiciliar probabilística. Se deben considerar nuevas estrategias de muestreo probabilístico para reducir los costos y efectos de agrupamiento.

ABSTRACT

OBJETIVOS: Avaliar completitude e oportunidade dos dados registrados no Sistema Nacional de Informação de Agravos de Notificação (SINAN) para os casos de febre maculosa (FM) no estado de São Paulo; Analisar as tendências das taxas de incidência e mortalidade por febre maculosa brasileira (FMB) com base na distribuição espacial de cada vetor; Investigar desfechos por locais de internação; Identificar quais as áreas de maior risco de ocorrência de FM, qual a sua distribuição por zona de ocupação humana e se este risco se manteve estável no território ao longo do período estudado; Projetar a provável evolução da ocorrência no tempo e no espaço. MÉTODOS: Esta tese está dividida em três manuscritos. Manuscrito 1: Trata-se de estudo descritivo e ecológico dos casos humanos confirmados de FM, notificados no SINAN de 2007 a 2017 no estado de São Paulo analisando atributos completitude e oportunidade de dez campos da ficha de notificação. Realizou-se regressão linear para avaliar as tendências das séries temporais (p<0,05). Manuscrito 2: Estudo de série temporal utilizando dados secundários de casos humanos confirmados de FMB por carrapato-vetor no estado de São Paulo, utilizando o software Joinpoint. Os dados foram georreferenciados pelos locais de internação. Manuscrito 3: Trata-se de estudo ecológico de varredura espaço-temporal de casos humanos confirmados notificados de FM com análise do risco de ocorrência da doença no local provável de infecção (LPI), por meio do SaTScan. RESULTADOS: Manuscrito 1: Foram analisados 736 registros. Dos campos essenciais, apenas Data da alta demonstrou baixa completitude (68,5%). Investigação e Encerramento tiveram boa oportunidade; demais intervalos não foram adequados. Manuscrito 2: Nas áreas de Amblyomma sculptum, houve tendência de aumento da incidência e mortalidade (ambos p<0,05), entre 2007 e 2015. Nas áreas de Amblyomma aureolatum, houve tendência de redução da incidência (p<0,05), enquanto a tendência de mortalidade permaneceu estável em todo o período estudado. A letalidade nos casos relacionados ao A. aureolatum foi maior do que nos casos de A. sculptum (67,1% contra 55,0%, p=0,037). A maioria dos pacientes foi hospitalizada próximo ao LPI. Manuscrito 3: No presente momento, comportamento predominantemente urbano para A. sculptum, A. aureolatum e Amblyomma ovale foi verificado, explicado pela atual expansão imobiliária e pelo maior contato de cães domésticos com áreas de floresta. Duas novas áreas potenciais de ocorrência da FM associadas a A. sculptum foram identificadas no período analisado; enquanto para A. aureolatum não houve nova área endêmica. CONCLUSÕES: No estado de São Paulo, a completitude dos dados de FM foi boa (80,0%) na maioria das variáveis estudadas, mas a oportunidade estudada não. Isso aponta para a importância de ações de educação e comunicação em saúde sobre FM. As curvas de incidência e mortalidade foram marcadamente diferentes de acordo com o carrapato-vetor, apontando para uma pior taxa de letalidade quando A. aureolatum foi implicado. Esses achados podem orientar ações específicas de vigilância e abordagens assistenciais, considerando os diferentes territórios. O delineamento ecológico com análise espaço-temporal permitiu melhor detecção de aglomerados de alto risco de distribuição da FM em humanos no espaço e no tempo, contribuindo para a estruturação de ações em saúde coletiva específicas para as diferentes áreas do estado.


AIM: To evaluate completeness and timeliness of data registered in the National Information System for Notifiable Diseases (SINAN) for spotted fever (SF) cases in the state of São Paulo; To analyze the trends of incidence and mortality rates caused by Brazilian spotted fever (BSF) based on each vector spatial distribution; To investigate outcomes by hospitalization sites; Identify which areas are most at risk for the occurrence of SF, their distribution by human occupation zone and whether this risk has remained stable in the territory throughout the period studied; Project the probable evolution of the occurrence in time and space. METHODS: This thesis is divided into three manuscripts. Manuscript 1: This is a descriptive and ecological study of confirmed human cases of SF, reported in Sinan from 2007 to 2017 in the state of São Paulo for completeness and timeliness of ten form fields. Linear regression was performed to analyze trends in the time series (p<0.05). Manuscript 2: A time-series study using secondary data of BSF confirmed human cases by tick-vector in the state of São Paulo, using Joinpoint software. Data was georeferenced by hospitalization sites. Manuscript 3: This was an ecological spatiotemporal clustering study of SF confirmed human cases. The risk analysis of disease occurrence by probable site of infection (PSI) was performed through SaTScan. RESULTS: Manuscript 1: A total of 736 registration were analyzed. Among essential fields, only Discharge date showed low completeness (68.5%). Investigation and Closure had good timeliness; other intervals were not adequate. Manuscript 2: In Amblyomma sculptum areas, there were upward incidence and mortality trends (both p<0.05), between 2007 and 2015. In Amblyomma aureolatum areas, there was a downward incidence trend (p<0.05), while the mortality trend remained stable through all studied period. Lethality rate in A. aureolatum related cases was higher than A. sculptum ones (67.1% against 55.0%, p=0.037). The majority of the patients were hospitalized near PSI. Manuscript 3: Currently, it was verified a predominantly urban behavior for A. sculptum, A. aureolatum, and Amblyomma ovale, which can be explained by the existing real estate expansion and by a higher exposure of pet dogs to forest areas. Two new areas with potential A. sculptum-related SF occurrence were identified, while there were no new endemic territories for A. aureolatum. CONCLUSIONS: In São Paulo, the completeness of SF data was good in most of the variables studied (80,0%), but not timeliness, highlighting the importance of education on SF. Incidence and mortality curves were markedly different according to tick-vector, pointing to a worse lethality rate when A. aureolatum was implicated. These findings may orient specific surveillance actions and assistance approaches, considering the different territories. This approach enabled a better quantification of high-risk spatiotemporal clusters of human SF, contributing for the tailoring of specific public health actions towards different state regions.
