ABSTRACT
Abstract Inspired by the POLYMOD study, an epidemiological survey was conducted in June 2021 in one of the most densely populated and socially vulnerable sectors of Belo Horizonte (Brazil). A sample of 1000 individuals allowed us to identify, within a 24-hour period, the rates of social contacts by age groups, the size and frequency of clique in which respondents participated, as well as other associated sociodemographic factors (number of household residents, location of contact, use of public transportation, among others). Data were analyzed in two phases. In the first one, results between two SIR models that simulated an eight-day pandemic process were compared. One included parameters adjusted from observed contact rates, the other operated with parameters adjusted from projected rates for Brazil. In the second phase, by means of a log-lin regression, we modeled the main social determinants of contact rates, using clique density as a proxy variable. The data analysis showed that family size, age, and social circles are the main covariates influencing the formation of cliques. It also demonstrated that compartmentalized epidemiological models, combined with social contact rates, have a better capacity to describe the epidemiological dynamics, providing a better basis for mitigation and control measures for diseases that cause acute respiratory syndromes.
Resumo Inspirado no estudo POLYMOD, foi realizado, em junho de 2021, um survey epidemiológico num dos setores de maior densidade populacional e vulnerabilidade social de Belo Horizonte (Brasil). Uma amostra de 1.000 domicílios permitiu identificar, num período de 24 horas, as taxas de contatos sociais por faixas etárias, o tamanho e a frequência de cliques do qual participou o respondente, assim como outros fatores sociodemográficos associados (número de moradores do domicílio, local do contato, uso do transporte público, entre outros). Os dados foram analisados em duas fases. Na primeira, foram comparados os resultados entre dois modelos SIR que simularam um processo pandêmico de oito dias. Um incluiu parâmetros ajustados a partir das taxas de contatos observadas. O outro operou com parâmetros ajustados a partir de taxas projetadas para o Brasil. Na segunda fase, mediante uma regressão log-lin, modelamos os principais determinantes sociais das taxas de contato, utilizando o adensamento de cliques como uma variável proxy. A análise dos dados mostrou que o tamanho da família, a idade e os círculos sociais são as principais covariáveis que influenciam a formação dos cliques. Também demonstrou que modelos epidemiológicos compartimentais, combinados com taxas de contato social, têm melhor capacidade de descrever a dinâmica epidemiológica, fornecendo uma melhor base para medidas de mitigação e controle de doenças que causam síndromes respiratórias agudas.
Resumen Con inspiración en el estudio POLYMOD, se hizo una encuesta epidemiológica, en junio de 2021, en uno de los sectores más densamente poblados y socialmente vulnerables de Belo Horizonte (Brasil). Una muestra de mil hogares permitió identificar, en un período de 24 horas, el tamaño y la frecuencia de los cliques en los que participó el encuestado, las tasas de contactos sociales por grupos de edad, así como otros factores sociodemográficos asociados (número de residentes en el hogar, lugar de contacto, uso del transporte público, entre otros). Los datos se analizaron en dos fases. En la primera, se compararon los resultados entre dos modelos SIR que simularon un proceso pandémico de ocho días. Uno incluyó parámetros ajustados a partir de tasas de contacto observadas; el otro operó con parámetros ajustados a partir de tasas proyectadas para Brasil. En la segunda, mediante una regresión log-lin, se modelaron los principales determinantes sociales de las tasas de contacto, utilizando la densificación de cliques como una variable proxy. El análisis de los datos mostró que el tamaño de la familia, la edad y los círculos sociales son las principales covariables que influyen en la formación de camarillas. También demostró que los modelos epidemiológicos compartimentados, combinados con tasas de contacto social, son más capaces de describir la dinámica epidemiológica, proporcionando una mejor base para las medidas de mitigación y control de las enfermedades causantes de síndromes respiratorios agudos.

Abstract INTRODUCTION: This epidemiological household survey aimed to estimate the prevalence of the current and past SARS-CoV-2 infections in Ribeirão Preto, a municipality of southeast Brazil. METHODS: The survey was conducted in two phases using a clustered sampling scheme. The first phase spanned May 1-3 and involved 709 participants. The second phase spanned June 11-14, 2020, and involved 646 participants. RESULTS: During the first phase, RT-PCR performed on nasopharyngeal swabs was positive at 0.14%. The serological tests were positive in 1.27% of the patients during the first phase and 2.79% during the second phase. People living in households with more than five members had a prevalence of 10.83% (95%CI: 1.58-74.27) higher than those living alone or with someone other. Considering the proportion of the positive serological test results with sex and age adjustments, approximately 2.37% (95%CI: 1.32-3.42) of the population had been cumulatively infected by mid-June 2020, which is equivalent to 16,670 people (95%CI: 9,267-24,074). Considering that 68 deaths from the disease in the residents of the city had been confirmed as at the date of the second phase of the survey, the infection fatality rate was estimated to be 0.41% (95%CI: 0.28-0.73). Our results suggest that approximately 88% of the cases of SARS-CoV-2 infection at the time of the survey were not reported to the local epidemiological surveillance service. CONCLUSIONS: The findings of this study provide in-depth knowledge of the COVID-19 pandemic in Brazil and are helpful for the preventive and decision-making policies of public managers.

Objective To investigate the epidemiology of echinococcosis in Serthar County, Sichuan Province, so as to provide insights into optimization of echinococcosis control measures. Methods The prevalence of human echinococcosis was surveyed among permanent residents living in Serthar County at ages of over 2 years from 2016 to 2019, and the prevalence of Echinococcus infections was surveyed in owned dogs, yaks and rodents in 2019. The epidemiological features of echinococcosis in humans and animals were descriptively analyzed. Results The overall prevalence of human echinococcosis was 3.72% (1 613/43 362) in Serthar County from 2016 to 2019, and the prevalence rates of cystic echinococcosis, alveolar echinococcosis and mixed infections of cystic echinococcosis and alveolar echinococcosis were 1.72% (745/43 362), 1.98% (860/43 362) and 0.02% (8/43 362), respectively. The prevalence of human echinococcosis was higher in pastoral areas (4.13%, 1 577/38 149) than in semi-agricultural and semi-pastoral areas (0.69%, 36/5 213) (χ2 = 151.82, P < 0.05); however, there was no significant difference in the prevalence between men (3.76%, 819/21 787) and women (3.68%, 794/21 575) (χ2 = 0.19, P > 0.05). Cystic echinococcosis was the predominant type in students with echinococcosis (93.78%, 422/450), while alveolar echinococcosis was the predominant type in herders with echinococcosis (72.16%, 801/1 110). There was a significant difference in the constituent ratio of echinococcosis types between students and herders (χ2 = 588.57, P < 0.05). In addition, higher prevalence of echinococcosis was detected in nomadic populations (4.58%, 1 008/22 021) than in community-dwelling populations (2.83%, 605/21 341) (χ2 = 91.88, P < 0.05). The Echinococcus copro-antigen-positive rate was 0.19% (4/2 157) in owned dogs, and the detection rate of echinococcosis was 8.00% (16/200) in yaks and 3.10% (31/1 000) in rodents in 2019. Conclusions Echinococcosis is highly prevalent in Serthar County, Sichuan Province. Sustained management of source of Echinococcus infections, improved treatment of echinococcosis patients and timely health education for nomadic populations are recommended.
ABSTRACT
Objective To investigate the epidemiological characteristics of chronic obstructive pulmonary disease (COPD) in patients aged 65 years and above in Liaoning Province. Methods Between January 2019 and December 2020, a cluster random sampling method was used to investigate residents ≥ 65 years old in Sujiatun Community, Shenyang City, Liaoning Province. The pulmonary function tests of the selected residents were conducted. Questionnaire surveys were carried out and 5738 questionnaires with complete data were analyzed. Results A total of 620 COPD cases were diagnosed among 5738 people investigated in the present study, with a total prevalence rate of 10.81%, of which the prevalence rate in men was 12.58% (371/2950), and the prevalence rate in women was 8.93% (249/2950). According to the GOLD classification of lung function, 620 patients can be divided into 186 (30.49%) cases of grade I, 266 (43.61%) grade II, 118 (19.34%) grade III, and 50 (8.20%) cases of grade IV. The problem with lung function in males was more serious than that in females, which increased gradually with age (P<0.05). Multivariate logistic regression analysis showed that gender, age, BMI, smoking, childhood respiratory history, family history, occupational exposure, indoor oil fume and use of polluted fuel for heating were independent risk factors affecting the onset of COPD (P<0.05). Conclusion The prevalence of COPD in patients aged 65 years old and above in Liaoning is relatively high. Gender, age, BMI, smoking, childhood respiratory history, family history, occupational exposure, indoor oil fume, and use of polluted fuel for heating are related to the onset of COPD. Clinical attention should be paid to early screening and prevention of COPD in those populations to reduce the prevalence of COPD..

A dor de caráter endodôntico acomete grande parte da população mundial que procura por tratamento de urgência em pronto atendimento. Poucos trabalhos observam a casuística e o protocolo de atendimento que estão inseridos nos prontos atendimentos como: diagnóstico, presença de selamento coronário provisório, utilização de medicação intracanal, medicação sistêmica e o retorno do paciente com dor. Mediante ao exposto, foi realizado uma pesquisa quantitativa descritiva, retrospectiva e documental, e o levantamento de protocolo de urgência nas seguintes instituições: Serviços de Pronto Atendimento da cidade de Araçatuba (PAO) e na Faculdade de Odontologia da Universidade Estadual Paulista de "Júlio de Mesquita Filho" (FOA/UNESP). Dados como tipo de medicação intracanal, selamento coronário, medicação sistêmica e retorno do paciente com dor foram tabulados e avaliados estatisticamente pelo software SigmaPlot 13.0. O protocolo FOA/PAO foram semelhantes nos diagnósticos de pulpite irreversível e necrose pulpar, não havendo associação (P>0.05). Houve associação (P<0.05) apenas no diagnóstico de abscesso endodôntico, o protocolo do PAO foi prescrever medicação sistêmica, não realizar selamento e não MIC, diferentemente da FOA. Referente a prescrição de medicação sistêmica, houve associação (P<0.05), pois o PAO realiza prescrição em todos os casos: pulpite irreversível, necrose e abscesso, já a FOA apenas em necrose e abscesso. No retorno do paciente com dor, nota-se associação (P<0.05) nos casos de abscesso que receberam MIC adversa e não retornaram com dor. Embora o protocolo FOA/PAO seja diferente para os casos de abscesso o objetivo do tratamento de urgência em ambas instituições foi alcançado, pois removeram a dor do paciente(AU)
Endodontic pain affects a large part of the world population, which leads for a seek for urgency treatment. Few reports studied the casuistry and protocol of dental care inserted in the prompt attendance, such as: diagnosis, provisional coronal sealing, in tracanal medication, systemic medication and patient with pain complaint. The objective of this study was to carry out a survey of the urgency protocol in both dental care institutions: Prompt Dental Care Services of Araçatuba city (PAO) and the Araçatuba School of Dentistry/Sao Paulo State Univ ersity Júlio de Mesquita Filho (FOA/UNESP). The medical records of patients who voluntarily sought care in the urgency department, with anamnesis and a description of the performed procedure, were evaluated. Data suc h as intracanal medication, coronary sea ling, systemic medication and patient return with pain complaint were tabulated and statistically evaluated via SigmaPlot 13.0 software, with no association of these variables and the patient return with pain complai nt (P> 0.05). However, association (P<0. 05) was observed between attendance institution where urgency was carried out and the presence of temporary coronal sealing in cases with abscess, whereas FOA performs the coronal sealing as attendance protocol and P AO doesn't. There was also an associatio n (P<0.05) between diagnosis, prescription of systemic medication and dental care attendance institution, since PAO performed the largest number of medication prescriptions. It is concluded that, although dental care attendance protocols were similar in ca ses of pulpitis or necrosis, differing only in abscess, the main objective of urgency treatment was achieved in both treatment protocols, since treated patients were painless for more than 7 days(AU)

ABSTRACT
Objective To investigate the prevalence and epidemiological characteristics of enuresis in children aged 5-13 years old in Jinshan District, Shanghai, and analyze the relevant pathogenic factors, so as to provide a reference for clinical prevention and treatment of enuresis in children and related psychological diseases. Methods Using the medical history collection table (CMT checklist) of ICCS (International Association for Urinary Control of Children) as a guidance, a random cluster sampling was performed on 1 000 preschool and school-age children from 9 representative schools with a relatively concentrated population in Jinshan District. Results Excluding the missing and invalid questionnaires, a total of 785 cases were included in the study, and the total prevalence of enulists in 5-13 children was 7.77% (61 cases), among which 42 cases were 5-7 years old (68.85%), 12 cases were 8-10 years old (19.67%), and 7 cases were 11-13 years old (11.48%). There were statistically significant differences among the age groups (χ2=52.87，P=0.001)). Among the affected children, 3.31% (26 cases) were in urban areas and 4.46% (35 cases) in rural areas (P<0.05). The prevalence of boys (38 cases) and the prevalence of girls (23 cases) were statistically significant (P<0.05). The characteristics of enuresis, organic diseases, and attention were analyzed in 61 children diagnosed with enuresis. Children with enuresis ≥7 times/week were the highest (33 cases), accounting for 54.10%; children with 3-6times/week (19 cases) accounted for 31.15%; 2 times/week (9 cases) accounted for 14.75%. Physical examination abnormalities (including urinary routine abnormalities: urinary tract infection, hematuria, high urinary calcium or phimosis) were found in 18 cases, accounting for 29.51%. Four patients (6.56%) had a family history of enuresis. Fifty-two (85.25%) of the affected children had psychologically related problems: introverted personality, impulsiveness, inferiority, lack of concentration, medium or inferior academic performance. Conclusion The prevalence of enuresis in 5-13 children was 7.77%. There were significant differences between urban and rural areas, different age groups and genders as well. Most sick children developed organic diseases and some degree of psychological problems. A timely diagnosis and treatment of enuresis in children in combination with psychological guidance and behavioral intervention is necessary for the prevention of the occurrence of enuresis related psychological problems.
ABSTRACT
The present study aimed to characterize the procedures performed by the oral and maxillofacial surgery team at a Brazilian reference hospital in a Brazilian city, as well as to describe the time trend of the number of services related to different types of surgery. It is a time-series study that assessed the data from the medical records of patients assisted at a reference hospital in a city in the state of Mato Grosso (Brazil), from 2011 to 2017. The data were assessed using descriptive statistical analysis, correspondence analysis (CA), and time trend analysis. A total of 1488 medical records were evaluated, the majority of which corresponded to male patients (59%), extractions were the most performed procedures (46.2%), local anesthesia was the most applied technique (50.3%), and the procedures were mostly performed in an outpatient environment (53.2%). There was a decreasing global time trend (R2 = 0.248; p < 0.001). Male patients are the most assisted in hospital care and are particularly related to more invasive procedures; there is also a decreasing curve of assistance over the years in the oral and maxillofacial surgery and traumatology service of the hospital studied.

Bovine alphaherpesvirus type 1 (BoHV-1) is the etiological agent responsible for serious infections that compromise the respiratory and genital tracts of affected cattle. In order to estimate the seroprevalence of BoHV-1 and to identify the associated risk factors in dairy farms in the city of Senador Guiomard, Acre, Brazil, the present study was carried out through the analysis of 180 blood serum samples submitted to the screening of anti-BoHV-1 by the virus neutralization test (VN) and by means of the evaluation of the epidemiological questionnaire applied in the eight investigated properties. The prevalence of seropositivity for BoHV-1 was 61.1%, ranging from 43.3 to 86.2% among the analyzed properties. The variable absence of veterinary assistance showed statistically significant association (odds ratio OR = 2.10; p < 0.001) with alphaherpesvirus infection. The results demonstrate that the frequency of BoHV-1 is high and needs to be controlled through prophylactic and health management measures.(AU)
O alfaherpesvírus bovino tipo 1 (BoHV-1) é o agente etiológico responsável por graves infecções que comprometem os tratos respiratório e genital dos bovinos acometidos. Com o objetivo de estimar a soroprevalência de BoHV-1 e identificar os fatores de risco associados em propriedades leiteiras do município de Senador Guiomard, Acre, foi realizado o presente estudo, por meio da análise de 180 amostras de soro sanguíneo submetidas à pesquisa de anticorpos anti-BoHV-1 pelo teste de vírus neutralização (VN) e por meio da avaliação do questionário epidemiológico aplicado nas oito propriedades investigadas. A prevalência de soropositividade para BoHV-1 foi de 61,1% variando de 43,3 a 86,2% entre as propriedades analisadas. A variável ausência de assistência veterinária apresentou associação estatisticamente significativa (odds ratio OR = 2,10; p < 0,001) com a infecção pelo alfaherpesvírus. Os resultados demonstram que a frequência de BoHV-1 é alta e precisa ser controlada através de medidas profiláticas e de manejo sanitário.(AU)

Through the epidemiological investigation on this patient and the related blood donors as well as laboratory detections, the source of infection was ascertained. This blood donor was an overseas student from Africa, whose blood sample was positive in the rapid diagnostic test, and the results of microscopic examination of peripheral blood smear and PCR both suggested P. falciparum positive.
ABSTRACT
Objective@#To identify the etiology and source of infection in a diarrhea outbreak in Yunnan in May 2017 and to provide the evidence for formulating prevention and control measures.@*Methods@#Epidemiological investigation was carried out on the epidemic situation of diarrhea in the village of Lvchun County in Yunnan Province, the field sampling, laboratory testing and data analysis were also performed.@*Results@#Among the 44 patients, 11 of the 13 samples were positive for rotavirus nucleic acid in group A, and the positive rate was 84.62%. The survey showed that the water supply pipe was damaged and polluted by human and livestock manure and domestic sewage. The trend of the damaged water pipe was basically the same as the case distribution, and the rainfall was significantly related to the number of the disease.@*Conclusions@#This event was an outbreak of diarrhea caused by group A rotavirus. The direct pollution of drinking water caused by rainfall may be the risk factor of this outbreak. The health management of rural drinking water should be strengthened and the health knowledge and education of preventing intestinal infectious diseases should be promoted.
ABSTRACT
Objective • To describe and analyze the epidemiological status of dental erosion in 3- to 5-year-old children in Shanghai. Methods • A cluster, multi-stage random sampling method was applied to 3- to 5-year-old children in Shanghai. Clinical oral examination was performed, and the status of dental erosion was evaluated by O'Sullivan index, including the involved tooth position, surface and severity. Descriptive analysis was applied for the prevalence of dental erosion and the distribution of tooth position and surface. Results • A total of 1 148 children aged from 3 to 5 years old in Shanghai were randomly selected. Among them, 168 children suffered from dental erosion, and the prevalence of dental erosion in the sample was 14.6%. A total of 102 males (17.3%) and 66 females (11.8%) showed the condition of dental erosion. The ratio of male and female was 1:0.68, and the prevalence of dental erosion in the male was significantly higher than that in the female (χ2=6.972, P=0.008). The upper second deciduous molar in the dentition was most likely involved (8.6%) and the lower later incisor was least involved (1.7%). The surface of occlusal or incisal surface was more likely involved (37.1%). With regard to the severity of dental erosion, the loss of horizontal enamel was more common (58.4%). Conclusion • The prevalence of dental erosion in the 3- to 5-year-old children in Shanghai is relatively high and it is necessary to raise the awareness of dental erosion prevention.
ABSTRACT
Objective To understand the epidemic status of clonorchiasis and awareness of prevention and control knowledge in Xinfeng County of Jiangxi Province, so as to provide the evidences for control measures. Methods The baseline survey was carried out with a clue in vestigation of raw-fish eating behavior in potential endemic areas in 2016.The residents were examined by stool tests. The metacercariae of Clonorchis sinensis in fish, the rediae and cercariae in freshwater mollusk were detected. The feces samples of cats, dogs and pigs were collected and examined by sedimentation technique. Meanwhile, the epidemic factors, health knowledge and behavior were also surveyed. Results The residents in 26 villages had the habit of eating raw freshwater fish, and 19.51% of the respondents had this habit. The average infection rates of the population, Parafossarulus striatulus, freshwater fishes and reservoir hosts were 21.56%, 0, 8.24% and 2.27%, respectively. The infection rate of the population increased with age. There was a significant positive correlation between the behavior and the infection rate of the population (r = 0.88, P < 0.01). Only 11.46% of the respondents knew that eating raw-fish might cause C. sinensis infection, and 5.28% of them knew that C. sinensis was harmful to health. Conclusions Twenty-six villages in five townships were endemic areas of clonorchiasis in Xinfeng County. The permanent solution of prevention and control of clonorchiasis is to strengthen the health education and change the habit of raw-fish eating gradually.

ABSTRACT
Objective To understand the malaria epidemic situation and characteristics in Jiangsu Province in 2016,so as to provide the evidence for formulating and adjusting the strategy and measures for malaria elimination. Methods The data of malaria cases in Jiangsu Province in 2016 were collected from China's Routine Diseases Surveillance Information System(CRD-SIS)and analyzed statistically.Results Totally,308 malaria cases were reported in Jiangsu Province in 2016,and the cases decreased by 23.95% compared to 405 malaria cases in 2015.Except for 1 malaria case that was caused by blood transfusion, the rest patients were all imported.Among the 308 cases,237 were infected with Plasmodium falciparum,11 were infected with P.vivax,8 were infected with P.malariae,51 were infected with P.ovale,and 1 was mixed infection.Among all the cities in Ji-angsu Province,the numbers of imported cases of Nantong(53 cases),Huai'an(41 cases),Taizhou(40 cases),Lianyungang (36 cases)and Yangzhou(29 cases)ranked in the top 5,and the total malaria cases in the five cities accounted for 64.61%. Conclusions There were no local malaria cases in Jiangsu Province for 5 consecutive years up to 2016.Although the imported cases decreased slightly compared to those in 2015,we still should strengthen the surveillance of imported malaria cases as well as improve malaria diagnosis and treatment abilities for related personnel at all levels of medical institutions.Also we should fo-cus on the Plasmodium check,focus survey and disposal to realize the aim of malaria elimination in Jiangsu Province in time.
ABSTRACT
Objective The aim of this study was to assess the risk factors and epidemiological characteristics of placental abruption (PA) in Hebei province.Methods A cross-sectional survey was conducted to collect data on 218 880 pregnant women who were hospitalized in 22 hospitals which were under a monitoring program,in Hebei province,from January 1,2013 to December 31,2016.Data regarding epidemiological characteristics as time distribution,population distribution and related risk factors of placental abruption were gathered and analyzed.Results In this cohort study,218 880 women were included,with 669 (0.31％) of the pregnant women having PA.The overall prevalence rates were higher in the South than in the north parts of the area and higher in more developed regional economic centers.The average age of women having the episode was (27.87 ± 4.50) years and presented “J” distribution on the prevalence of maternal age.Results from the multivariate regression analysis showed that the following factors were independently at risk for placental abruption:pregnancy the including hypertension (OR=1.65,95％CI:1.09-2.50),mild preeclampsia (OR=3.65,95％CI:2.40-5.56),severe preeclampsia (OR=4.72,95％CI:3.86-5.76) and anemia (OR=2.41,95％CI:2.05-2.83) which were all increased in pregnant women with PA compared with the normal female population without placental abruption.Conclusions Placental abruption seemed to be associated with a moderate increasing risk of age,and was seen higher in those population older than 35 or younger than 20 year-olds.It was suggested that appropriate inoculation programs should be taken in different regions,especially on high-risk groups.Health education on related disease was of great significance for improving the prenatal outcome.
