Introduction: Work-related musculoskeletal disorders are injuries resulting from the excessive use of the musculoskeletal system. This study analyzed musculoskeletal symptoms and associated factors in primary school teachers in the municipal public network in Cuiabá, Mato Grosso. Methods: A cross-sectional study was conducted with 326 teachers. Data collection instruments included the Vocal Production Condition, Self-Reporting Questionnaire, and Nordic Musculoskeletal Questionnaire. The dependent variable was the presence or absence of musculoskeletal symptoms. Bivariate analysis using chi-square test and prevalence ratios with 95% confidence intervals, as well as multiple analysis using Poisson regression model, were performed. Results: In the multiple analysis, it was found that the presence of musculoskeletal symptoms was significantly associated (p<0.05) with the following risk factors: common mental disorders (PRa=1.45), regularly lifting weights (PRa=1.26), and performing intense physical effort (PRa=1.22). Additionally, a significant association was identified between these symptoms and contracted teachers (PRa=0.82), as well as an interaction between performing intense physical effort and regularly lifting weights (PRa=0.75), which acted as protective factors for symptom presence. Conclusion: It is concluded that work characteristics were important risk factors for the development of musculoskeletal symptoms in the last twelve months. The results of this study are believed to provide a basis for decision-making by managers and stakeholders in implementing preventive measures in the work environment of these teachers. (AU)

Abstract Introduction The pandemic has generated challenges which impact the mental health of the population, including postgraduate healthcare students. Objective To evaluate the factors associated with depression in postgraduate healthcare students during the COVID-19 pandemic. Method This is a cross-sectional study with postgraduate healthcare students, with a sample of 117 participants. The data were collected through an online form, between September and November 2021, using semi-structured questionnaires with sociodemographic information and information regarding participants' mental health, as defined by the DSM-5 Scale, where the depression domain was considered a variable for this study. The variables were tested using the Poisson multiple regression model with robust variance in the bivariate analysis between the dependent and independent variables (95% CI). Results In the bivariate analysis, there was an association between depression and not having a partner, also a low monthly income, studying for a master's or professional doctorate and having an employment relationship parallel to the postgraduate course. Regarding the mental health of the participants, the following factors were associated with depression: anger, mania, anxiety, somatic symptoms, suicidal ideation, mental disorder, memory, repetitive thinking, dissociation, personality functioning, and substance use (p < .05). In the multiple analysis, it was found that mania, anxiety, and dissociation remained statistically associated with depression (p < .05). Discussion and conclusion Factors associated with depression in this population raise the importance of mental health promotion interventions for postgraduate healthcare students, who seek help both through mental health services and through their universities.

[Prevalence of SARS-CoV-2 antibodies in the State of Mato Grosso, Brazil: a population-based survey]. / Prevalência de anticorpos contra SARS-CoV-2 em Mato Grosso, Brasil: pesquisa de base populacional.

Seroprevalence data provide relevant information on the development and progression of the COVID-19 pandemic. The study aimed to estimate the prevalence of SARS-CoV-2 antibodies in Mato Grosso State, Brazil, and its distribution according to sociodemographic and economic characteristics. This population-based serological survey was conducted in September-October 2020 in individuals 18 years or older in ten municipalities (counties) in the state of Mato Grosso. Interviews and collection of biological samples were conducted in the households, and determination of IgG antibodies to SARS-CoV-2 was performed with chemiluminescence. A total of 4,306 individuals were evaluated, and COVID-19 prevalence was estimated at 12.5% (95%CI: 10.5; 14.7), ranging from 7.4% to 24.3% between municipalities. No significant differences were found in prevalence of infection according to race/color, schooling, or family income, but lower prevalence was seen in individuals with a pensioner living in the same household, who did not receive emergency financial aid, and whose family income had not decreased after social distancing measures during the epidemic. Estimated prevalence of SARS-CoV-2 antibodies in this population-based survey is essential to measure the magnitude of the disease and will back measures to confront and control the pandemic.

No se encontraron diferencias en la prevalencia de infección según la raza/color de la piel, la educación o los ingresos familiares; sin embargo, se encontró una menor prevalencia entre los individuos que vivían con un residente que recibía una pensión, que no recibía ayuda económica de emergencia y que los ingresos familiares no disminuyeron tras las medidas de distanciamiento social para hacer frente a la pandemia. La prevalencia de anticuerpos contra el SARS-CoV-2 estimada en esta investigación de base poblacional es imprescindible para conocer la magnitud de la enfermedad en el estado y subvencionar las acciones de enfrentamiento y control de la pandemia.

Attitudes of health professionals towards suicidal behavior: an intervention study.

OBJECTIVE: To evaluate the effect of an educational intervention on the attitudes of primary healthcare providers regarding patients with suicidal behavior. METHODS: Clinical trial randomized by clusters, with a sample of 261 healthcare professionals, from 22 health units selected by stratified sampling, were chosen and randomly allocated, by drawing, into two groups: intervention (n = 87) and control (n = 174). The participants of the intervention group were exposed to a 20-hour training on suicidal behavior. All 261 participants were evaluated before and after the intervention; the groups were compared to evaluate their attitude towards suicidal behavior using the Suicide Behavior Attitude Questionnaire (SBAQ), an evaluation made by comparison of the means via t-Student test, for independent samples, and paired t-test, for dependent samples. RESULTS: The intervention group, in comparison to their evaluation before and after training, as well as in the comparison with the evaluation of the control group, showed statistically significant differences in attitudes towards suicidal behavior, according to the differences presented in the scores for the domains: "perception of professional capacity," in all four items; "negative feeling," in six of the seven items; and in the "right to commit suicide" domain, in three of the five items. CONCLUSION: The brief training developed in primary health care was effective to improve the attitudes of the participants who were part of the intervention group regarding patients with suicidal behavior.

Recent dengue virus infection: epidemiological survey on risk factors associated with infection in a medium-sized city in Mato Grosso

ABSTRACT BACKGROUND: Dengue is considered to be the most important arbovirus worldwide, with important complications that increase its lethality. In Brazil, an endemic country, the disease reaches significant incidence levels, with occurrences of serious cases and high costs of hospitalizations for its treatment. OBJECTIVE: To analyze risk factors among individuals with recent histories of dengue infection in a medium-sized city in Mato Grosso. DESIGN AND SETTING: Descriptive cross-sectional study, of epidemiological-survey type, conducted among the urban population of a city located in mid-northern Mato Grosso. METHODS: A seroepidemiological survey using questionnaires and collection of biological material was conducted among 596 adults aged ≥ 18 years who had been selected through a cluster sampling process. Positive dengue cases were those with positive results from anti-dengue immunoassays (ELISA). Statistical analyses with descriptive and inferential techniques were used, with 95% confidence intervals and a 5% significance level. RESULTS: The seroepidemiological profile of the study participants was predominantly female, with ages between 18 and 39 years, self-declared non-white race/color, not more than eight years of education and not living with a companion. Among the sanitary factors analyzed, the following were risk factors for dengue virus infection: no running water at home; no water supply from the public piped network; no waste from drains or toilets sent to the sewage network; endemic disease combat agents visiting the home; and presence of mosquito breeding sites at home. CONCLUSION: Low schooling levels and previous dengue virus infection were associated with current dengue virus infection.

RESULTS The intervention group, in comparison to their evaluation before and after training, as well as in the comparison with the evaluation of the control group, showed statistically significant differences in attitudes towards suicidal behavior, according to the differences presented in the scores for the domains: "perception of professional capacity," in all four items; "negative feeling," in six of the seven items; and in the "right to commit suicide" domain, in three of the five items. CONCLUSION The brief training developed in primary health care was effective to improve the attitudes of the participants who were part of the intervention group regarding patients with suicidal behavior.

RESUMO OBJETIVO Avaliar o efeito de uma intervenção educativa sobre comportamento suicida nas atitudes dos profissionais de saúde da atenção primária. MÉTODO Ensaio clínico randomizado por conglomerados, com amostra de 261 profissionais de saúde, provenientes de 22 unidades de saúde selecionados por amostragem estratificada, elegidos e alocados aleatoriamente, mediante sorteio, em dois grupos: intervenção (n = 87) e controle (n = 174). Os participantes do grupo intervenção foram expostos a uma capacitação sobre comportamento suicida com duração de 20 horas. Todos os 261 participantes foram avaliados, antes e após a intervenção, e os grupos foram comparados para avaliar a atitude frente ao comportamento suicida utilizando o Suicide Behavior Attitude Questionnaire (SBAQ), avaliação feita por comparação das médias via teste t-Student para amostras independentes e Teste t pareado para amostras dependentes. RESULTADOS O grupo intervenção, na comparação intragrupos antes e depois da capacitação, bem como na comparação com o grupo controle, demonstrou diferenças estatisticamente significativas nas atitudes frente ao comportamento suicida, avaliadas a partir das diferenças de scores nos domínios: "percepção da capacidade profissional", em todos os quatro itens; "sentimento negativo", em seis dos sete itens; e no domínio "direito ao suicídio", três dos cinco itens. CONCLUSÃO A capacitação breve desenvolvida na atenção primária à saúde foi efetiva para a melhora das atitudes dos participantes que integravam o grupo intervenção frente ao comportamento suicida.

Prevalência de anticorpos contra SARS-CoV-2 em Mato Grosso, Brasil: pesquisa de base populacional / Prevalence of SARS-CoV-2 antibodies in the State of Mato Grosso, Brazil: a population-based survey / Prevalencia de anticuerpos contra el SARS-CoV-2 en Mato Grosso, Brasil: encuesta de base poblacional

Dados de soroprevalência oferecem informações relevantes relacionadas ao desenvolvimento e progressão de pandemia da COVID-19. Estimar a prevalência de anticorpos anti-SARS-CoV-2 em Mato Grosso, Brasil e sua distribuição segundo características sociodemográficas e econômicas. Inquérito soroepidemiológico de base populacional conduzido entre setembro e outubro de 2020, com indivíduos de 18 anos ou mais de idade, em dez municípios do Estado de Mato Grosso. As entrevistas e coleta de material biológico foram realizadas em domicílio, e a determinação de anticorpos IgG contra o SARS-CoV-2 foi feita por meio da quimioluminescência. Foram 4.306 indivíduos avaliados, e a prevalência de COVID-19 foi estimada em 12,5% (IC95%: 10,5; 14,7), variando de 7,4% a 24,3% entre os municípios. Não foram verificadas diferenças na prevalência da infecção segundo raça/cor da pele, escolaridade ou renda familiar, entretanto verificou-se menor prevalência entre indivíduos que residiam com algum morador que recebia aposentadoria, que não receberam auxílio financeiro emergencial e que a renda familiar não diminuiu após as medidas de distanciamento social para enfrentamento da epidemia. A prevalência de anticorpos contra SARS-CoV-2 estimada nesta pesquisa de base populacional é essencial para conhecer a magnitude da doença no estado e subsidiará ações de combate e controle da pandemia.

Seroprevalence data provide relevant information on the development and progression of the COVID-19 pandemic. The study aimed to estimate the prevalence of SARS-CoV-2 antibodies in Mato Grosso State, Brazil, and its distribution according to sociodemographic and economic characteristics. This population-based serological survey was conducted in September-October 2020 in individuals 18 years or older in ten municipalities (counties) in the state of Mato Grosso. Interviews and collection of biological samples were conducted in the households, and determination of IgG antibodies to SARS-CoV-2 was performed with chemiluminescence. A total of 4,306 individuals were evaluated, and COVID-19 prevalence was estimated at 12.5% (95%CI: 10.5; 14.7), ranging from 7.4% to 24.3% between municipalities. No significant differences were found in prevalence of infection according to race/color, schooling, or family income, but lower prevalence was seen in individuals with a pensioner living in the same household, who did not receive emergency financial aid, and whose family income had not decreased after social distancing measures during the epidemic. Estimated prevalence of SARS-CoV-2 antibodies in this population-based survey is essential to measure the magnitude of the disease and will back measures to confront and control the pandemic.

No se encontraron diferencias en la prevalencia de infección según la raza/color de la piel, la educación o los ingresos familiares; sin embargo, se encontró una menor prevalencia entre los individuos que vivían con un residente que recibía una pensión, que no recibía ayuda económica de emergencia y que los ingresos familiares no disminuyeron tras las medidas de distanciamiento social para hacer frente a la pandemia. La prevalencia de anticuerpos contra el SARS-CoV-2 estimada en esta investigación de base poblacional es imprescindible para conocer la magnitud de la enfermedad en el estado y subvencionar las acciones de enfrentamiento y control de la pandemia.

Poor glycemic control and associated factors in diabetic people attending a reference outpatient clinic in Mato Grosso, Brazil.

OBJECTIVES: To identify the proportion of poor of glycemic control and associated factors among people with type 2 diabetes attending a regional reference outpatient clinic in Mato Grosso (Brazil). METHODS: This is a cross-sectional quantitative study based on data from medical records of 338 people with type 2 diabetes who attend a state reference outpatient clinic in Mato Grosso (Brazil). Information on glycemic control, sociodemographic factors, lifestyle and clinical conditions was collected. RESULTS: The prevalence of elevated glycated hemoglobin was 47.34%. In the Poisson multiple regression model analysis with robust variance, poor glycemic control was significantly associated (p<0.05) with the following factors: insulin use (Prevalence Ratio -PR = 2.03), fasting glucose ≤70 and ≥100 mg/dL (PR = 2.0), postprandial glucose ≥180 mg/dL (PR = 1.76), no physical activity (PR = 1.62), the interaction between age group ≤59 years and the time of disease diagnosis >10 years (PR = 1.58), and presence of arterial hypertension (PR = 0.79). CONCLUSIONS: Most users of the reference outpatient clinic with type 2 diabetes had poor glycemic control associated with risk factors that alter glycated hemoglobin and negatively affect the achievement of established glycemic levels.

Knowledge and actions for the control of the vector Aedes aegypti in a municipality in the Legal Amazon.

Infections caused by arboviruses that have mostly impacted the Brazilian morbidity and mortality are caused by the same vector, Aedes aegypti. Preventive actions related to the vector are the most effective strategies in the prevention and control of these diseases. This study aimed to associate the knowledge on the vector that transmits dengue, Zika and chikungunya with the sociodemographic and behavioral preventive practices towards Aedes aegypti in the municipality of Tangara da Serra, Mato Grosso State, in the Brazilian Legal Amazon. A probabilistic urban population sampling was obtained by clusters: census sectors and households. The sample size calculation considered 10% of loss and a 1.5 design effect. This is a cross-sectional research carried out through a household survey in February and March 2018. There were 583 participants. The study variables were knowledge on the vector, sociodemographic characteristics and preventive practices related to the vector. The statistical analysis was based on a bivariate analysis and Poisson multiple regressions. Inadequate or insufficient knowledge on the vector Aedes aegypti remained associated with education in the categories illiterate (p<0.001) and 8 years of study or less (p<0.001), in addition to not adopting practices of capping and cleaning the water tank (p=0.002) and not using insecticides at home (p=0.007). It is concluded that there is a need for health communication actions that consider characteristics the population, especially the level of education and previous knowledge on the vector, allowing a dialogical approach and enabling the community participation in preventive practices and control of the vector Aedes aegypti .

Serological evidence of Bartonellosis in an indigenous community in the Brazilian Legal Amazonia.

BACKGROUND: Due to immunological susceptibility, close contact with the environment and way of life, indigenous communities are in a highly vulnerable condition to be affected by zoonoses, such as bartonellosis. METHODS: Seventy three paired serum samples were collected from indigenous people from a region of the Brazilian Legal Amazon, in cohorts carried out in 2014 and 2015, with the performance of serological tests by indirect immunofluorescence to detect anti-Bartonella IgG antibodies. The interviews and laboratory results were double entered in the EpiInfo 7 software, and the data processing was performed in the MiniTab 17 software. RESULTS: 5.47% of the indigenous people were seroreagent. The female gender was predominant (65.75%), aged between 20 and 39 years old (39.73%) with complete elementary school (42.47%). As for housing, wooden residences predominated (50.68%). Rodents were seen by 46.58% of the interviewees, and 55.88% of them reported that the animal was close to or inside the house. It was identified that each indigenous family, in its majority, had four to six cats, for the function of hunters of rodents. CONCLUSION: The high concentration of domestic cats, the close contact of indigenous people with wild rodents and the lack of care and poor hygiene of both are aspects that imply the possibility of infection by Bartonella sp. Health surveillance through seroepidemiological studies is essential to find evidence of the circulation of bartonellosis in these populations.

Orthohantavirus Survey in Indigenous Lands in a Savannah-Like Biome, Brazil.

In Brazil, the first confirmed cases of hantavirus cardiopulmonary syndrome in Indigenous populations occurred in 2001. The purpose of this study was to determine the seroprevalence of orthohantavirus infections in the Utiariti Indigenous land located in the southeastern region of the Brazilian Amazon. In December 2014 and 2015, a survey was conducted using an enzyme-linked immunosorbent assay in nine villages belonging to the Haliti-Paresí Indigenous communities. A total of 301 participants were enrolled in the study. Of the two study cohorts, the one from 2014 showed a prevalence of 12.4%, whereas the one from 2015 had a serum prevalence of 13.4%. Analysis of the paired samples of 110 Indigenous people who participated in both stages of the study enabled identification of four individuals who had seroconverted during the study period. Identifying the circulation of orthohantaviruses in the Utiariti Indigenous land highlights a serious public health problem in viral expansion and highlights the need to implement preventive measures appropriate to the sociocultural reality of these communities.
