Fatores associados à prática de atividade física entre universitários durante o isolamento social- pandemia covid-19

Abstract This study sought to analyze the practice of physical activity (PA) among university students, during the COVID-19 pandemic, and associated factors. This is a cross-sectional study with an analytical approach, carried out with 857 university students enrolled in higher education institutions in Montes Claros, in the state of Minas Gerais. Data collection was carried out using the Google forms, which was shared via social networks, containing questions regarding sociodemographic profile, physical activity, clinical factors, and behavioral and health habits. A descriptive exploratory analysis of the data was carried out, with frequency distribution of the study variables. Subsequently, bivariate analyses were performed and the associated variables with up to a level of 20% (p ≤ 0.20) were selected for multiple analysis using Poisson Regression. The prevalence non-practice of PA during the pandemic was of 56.8% among college students. Variables, such as being with a partner (PR=1.28), presence of respiratory diseases (PR=1.17), negative self-perception of health (PR=1.37), increased consumption of ultra-processed foods (PR=1.29), and presence of depression (PR=1.21), showed statistically significant associations with the practice of physical activity. We concluded that the non-practice of PA in university students during the social isolation caused by the COVID-19 pandemic is associated with marital status, presence of respiratory diseases, negative self-perception of health, increased consumption of ultra-processed foods, and presence of depression.

A insegurança das barragens da Vale em Minas Gerais, Brasil: aplicação da teoria da atividade à análise de desastres

Abstract The objective of this article is to point out hypotheses of contradictions historically incubated in Vale’s activity systems and that may have led to Brazil’s biggest environmental disaster, the B I dam break in Brumadinho, and the interdiction of many other dams owned by Vale in the state of Minas Gerais, Brazil. This is a case analysis from secondary data available in interviews, documents, and texts published in different media between 2011 and 2021. We try to demonstrate, from the Historical-Cultural Theory of Activity, the contradictions verified in and between Vale’s activity systems, since the company distributed large dividends to its shareholders, remunerated its directors as never before, reduced costs in relation to incomes, and brutally reduced internal debt, but keeping insufficient investments in dam management, culminating with the break of B I in 2019 and with 29 dams interdicted in March 2021. Financialization has become central to the company’s operations. This study points to a methodological path of the interdisciplinary dialogue to help clarify how strategic managerial decisions, especially those of financial management, could influence the production, maintenance, and safety management of tailings dams.

Evolução da severidade do cancro e qualidade de fuste no crescimento do mogno-africano

Abstract The objective of this work was to investigate the influence of the qualitative traits canker severity and stem quality on the mean annual increment (MAI) in diameter, total height, and stem height of an African mahogany (Khaya grandifoliola) stand. The study area is located in the state of Minas Gerais, Brazil, where continuous forest inventories were conducted over six years for data collection. Given the nonparametric characteristic of the data, an aligned rank transform analysis of variance was performed for each factor, and the averages were compared by Dunn’s multiple test. There was no significant effect of the interaction between the classes of canker severity and stand age. Increased canker severity has a significant effect on MAI values, causing reductions of 13% in diameter, 11% in total height, and 21% in stem height in trees from the highest canker severity class, when compared with the healthy ones. Age interacts significantly with stem quality, and MAI values tend to be similar in younger trees, differing over time in the oldest ones. In addition, the highest MAI values are recorded in trees with the best stem classification.

Perfil lipídico de queijo minas artesanal de regiões certificadas no estado de Minas Gerais, Brasil

Abstract The objective of this work was to determine the fatty acid profile of artisanal Minas cheese from seven certified regions in the state of Minas Gerais, Brazil. A total of 78 samples were collected in regions where the producers were registered by Instituto Mineiro de Agropecuária. For lipid profile determination, different cheese varieties from the following regions were analyzed: Canastra, Serro, Araxá, Serra do Salitre, Triângulo Mineiro, Campo das Vertentes, and Cerrado. The lipid profile of Serra do Salitre and Araxá cheeses was similar in caproic acid (C6:0), total polyunsaturated fatty acids, and ratio of polyunsaturated and saturated fatty acids. In the other regions, lipid profile differed due to associations with specific fatty acids, such as those of the cheeses from Triângulo Mineiro with C20:5n3, of Cerrado with C20:4n6, of Canastra with C8:0, of Serro with C22:2 and C22:6n3, and of Campo das Vertentes with C17:0, C18:0, and C20:0. The fatty acid profile and nutritional indices related to the lipid profile of artisanal Minas cheeses differ according to the region of origin. The content and profile of omega 3 fatty acids are significant parameters to differentiate artisanal Minas cheeses. Serro artisanal Minas cheese presents superior nutritional indices concerning fatty acid profile than the other studied cheeses.

Estimative of reference flows for water resources planning and control: hydrologic regional indicators application

Due to limitations of hydrometeorological monitoring network related to spatial station distribution and extension of historical series, tools that aim to improve consistency and optimize available data analysis have become essential. In this context, regionalization techniques stand out, once the main focus is the delimitation of hydrologically homogeneous regions with the subsequent spatial transposition of hydrological variables of interest. Regional indicators, defined as the mean values of hydrological variables and characteristics of a homogeneous region, constitute an expeditious approach to hydrological regionalization. The main perspective of the study was to evaluate the use of regional indicators when quantifying reference flows associated with average flow, drought, or flood conditions. The study area selected was the Manhuaçu River basin, a major Doce River tributary, located in the state of Minas Gerais, Brazil. The results showed that the regional indicators allow estimates of diverse reference flows with mean errors lower than 30%, considered satisfactory for the study area. However, the conventional method of flow regionalization presented more consistent results, with mean errors usually lower than 20%, regardless of the reference flow analyzed. It was also observed that adopting historical flow series with varied extensions did not produce relevant differences when appropriating the diverse reference flows for the Manhuaçu River basin, with none exceeding 3%.

Relevance of social networks in social mobilization to deal with arboviruses in the municipality of Betim, in the State of Minas Gerais, Brazil

This article consists of an analysis of the social networks of the residents of a community in Betim, in the State of Minas Gerais, Brazil, to understand how they can be used in social mobilization strategies against dengue, zika, and chikungunya within the territory. The life trajectory method was used to analyze the events and social conditioning factors of the formation, maintenance, and rupture of these networks, the quality and intensity of the bonds, the characteristics of social capital, and its variation along the trajectory of individuals. The understanding of the structure of the networks highlights some important aspects for the elaboration of new social mobilization strategies within the scope of the health surveillance proposal to be implemented locally. Within the trajectory of the interviewees, the neighborhood was revealed as an important network of reciprocity and provision of resources in daily life, considering the physical proximity and the duration of the relationships. Additionally, religious networks have a significant presence in the daily lives of residents, being strongly anchored in the provision of social "assistance" guided by solidarity values. We believe that the popular committees can stimulate these networks, especially the religious ones, to use their cultural and symbolic repertoire to work on issues of interest to the neighborhoods, such as the promotion of health, promotion of healthy and sustainable territories, local development and income generation, infrastructure improvement, and environmental preservation.

Distribuição espacial do estado nutricional de adolescentes de um município brasileiro nos anos iniciais da pandemia

ABSTRACT Objective This study aims to build geographic models related to the nutritional status of adolescents and describe territories regarding the prevalence of malnutrition, overweight, and obesity, in order to spatially represent how the nutritional status of adolescents is distributed in the city. Methods Using geocoding techniques, graphic models were built using data from the SISVAN platform, as well as the addresses and nutritional status of adolescents aged 10 to 19 years in the municipality of Divinópolis, in the state of Minas Gerais (Brazil), between 2020 and 2021. Results There was a prevalence of 34% of obesity and overweight in the 2020 and 2021 samples. The graphical models showed that there is no specific pattern of points for the spread of nutritional diagnoses, but it was possible to identify areas of heat and places with a higher concentration of overweight. Underweight had a homogeneous spread and did not stand out in the formation of profiles. Conclusion Geographic tools with the adolescents’ nutritional profile were successfully modeled, which have the potential to contribute to better health indicator management in the assessed territory, even with the limitations of the study.

Cianamida hidrogenada na brotação da macieira ‘Eva’ em região de inverno ameno

Abstract This study was carried aiming to evaluate different hydrogen cyanamide concentrations (0.00%; 0.26%; 0.52% 0.78% and 1.04%) associated with (3%) mineral oil on the bud growth of the ‘Eva’ apple tree in a high-altitude tropical climate region in the state of Minas Gerais. Sprouting percentage, fruit set: ratio between number of fruits and number of flowers (%), number of fruits per plant and flowering phenology were evaluated during the 2020 and 2021 production cycles. Even not being submitted to temperatures below 7.2°C, the ‘Eva ‘ cultivar completed its production cycle in two subsequent years. Hydrogen cyanamide application combined with mineral oil promoted increased budbreak and flowering uniformity, in addition to anticipating the beginning of flowering of the ‘Eva’ apple cultivar.

Spatio-temporal GAMLSS modeling of the incidence of schistosomiasis in the central region of the State of Minas Gerais, Brazil.

In Brazil, millions of people live in areas with risk of schistosomiasis, a neglected chronic disease with high morbidity. The Schistosoma mansoni helminth is present in all macroregions of Brazil, including the State of Minas Gerais, one of the most endemic states. For this reason, the identification of potential foci is essential to support educational and prophylactic public policies to control this disease. This study aims to model schistosomiasis data based on spatial and temporal aspects and assess the importance of some exogenous socioeconomic variables and the presence of the main Biomphalaria species. Considering that, when working with incident cases, a discrete count variable requires an appropriate modeling, the GAMLSS modeling was chosen since it jointly considers a more appropriate distribution for the response variable due to zero inflation and spatial heteroscedasticity. Several municipalities presented high incidence values from 2010 to 2012, and a downward trend was observed until 2020. We also noticed that the distribution of incidence behaves differently in space and time. Municipalities with dams presented risk 2.25 times higher than municipalities without dams. The presence of B. glabrata was associated with the risk of schistosomiasis. On the other hand, the presence of B. straminea represented a lower risk of the disease. Thus, the control and monitoring of B. glabrata snails is essential to control and eliminate schistosomiasis; and the GAMLSS model was effective in the treatment and modeling of spatio-temporal data.

Diagnosis of the risk of occupational disease among outsourced workers.

The outsourcing of work activities has caused new and precarious working conditions, impacting the health and safety of workers, resulting in an increase in disease and accidents given the vulnerability established in the contemporary labor market. To identify the occurrence of risk of disease resulting from work, among outsourced workers. Quantitative, observational, analytical and cross-sectional study, with application of the Inventário de Trabalho e Riscos de Adoecimento in 187 workers of a company that supplies and manages human resources for third parties, under contract with a Federal University, located in the state of Minas Gerais. The Inventário de Trabalho e Riscos de Adoecimento obtained the following averages for the following factors: work organization, 2.9 (standard deviation = 0.6) (critical); working conditions, 2.4 (standard deviation = 0.7) (critical); physical cost, 3.9 (standard deviation = 0.6) (severe); physical damage, 2.1 (standard deviation = 1.3) (critical). The participating workers showed a good perception associated with the Inventory of Inventário de Trabalho e Riscos de Adoecimento factors, resulting in diagnoses with the presence of risks of disease and accidents resulting from work.

Perfil de utilização de psicofármacos durante a pandemia de COVID-19 em Minas Gerais, Brasil

ABSTRACT Objective: To describe the profile of dispensation of mental health drugs by analyzing trends in use before and during the COVID-19 pandemic within the Unified Health System (Sistema Único de Saúde [SUS]). Methods: Pharmacoepidemiological study based on the retrospective analysis of records regarding the dispensation of psychotropic medicines in the SUS database in the state of Minas Gerais between 2018 and 2021, considering the periods before (2018–2019) and during the COVID-19 pandemic (2020–2021). A database with the records of dispensation of municipalities was created, and the consistency of releases was verified using the Analysis of Variance (ANOVA) test. Medicine consumption was measured in a defined daily dose (DDD) per 1,000 inhabitants/day for SUS, and the difference between periods was evaluated using Student's t-test. Results: During the COVID-19 pandemic, there was an increase in the consumption of psychotropic drugs in SUS-MG. The most consumed medicines were fluoxetine hydrochloride, diazepam and phenobarbital sodium (DDD=5.89; 3.42; 2.49) in the Basic Pharmaceutical Services Component(CBAF), and olanzapine, risperidone and quetiapine hemifumarate (DDD=0.80; 0.47; 0.38) in the Specialized Pharmaceutical Services Component (CEAF). The highest percentage increase in consumption was attributed to clonazepam (75.37%) and lithium carbonate (35.35%), in CBAF, and levetiracetam (3,000.00%) and memantine hydrochloride (340.0%) in CEAF. Conclusion: The change in the psychotropic drug dispensation profile during the COVID-19 pandemic highlights the need to produce more studies to complete, confirm or rule out this profile and monitor the use of psychotropic drugs by the population in the post-pandemic context.

Organizational Support for Entrepreneurial Orientation: The Perception of Professionals from Early Childhood Education Centers in Brazil

Entrepreneurial Orientation (EO) has become increasingly prominent in the public sector and in educational organizations. A policy for educational management based on EO has dimensions related to innovation, proactiveness, and risk-taking, which are preceded by organizational characteristics such as management support, discretion/autonomy, rewards/recognition, organizational boundaries, and time availability. The objective of this study is to analyze the organizational characteristics that influence EO in Municipal Centers for Early Childhood Education (Centros Municipais de Educação Infantil - CEMEIs) in Brazil. The study was conducted in a town in the state of Minas Gerais and involved 15 CEMEIs, applying questionnaires to education professionals as coordinators, monitors, and teachers, whose data were processed using descriptive statistics and a structural equation model. The results present a construct for validating organizational characteristics that can influence EO in public early childhood education organizations. However, autonomy and management support were the determinants of EO in the organizations studied. Finally, there are implications and considerations for policies and strategies in public educational organizations, indicating EO as a way to deal with contingencies, resource scarcity, the stimulation of (intra)entrepreneurial culture and even potential early childhood education for entrepreneurship.

Evaluation of clinical, pathological and epidemiological profile of patients with breast cancer in the microregion of Lavras – MG

Introduction: Breast cancer is associated with high frequency and mortality in Brazilian women. There have been limited studies portraying the characteristics of breast cancer cases in the countryside of the state of Minas Gerais for a long period of time, a fact that will allow us to better understand the epidemiology of these tumors. This descriptive study aims to analyze the epidemiology and clinical features of patients with breast cancer treated at a public health service facility in Lavras, MG. Methods: This is a transversal study with 299 women diagnosed with breast cancer between 2002 and 2022, based on data collection from medical records and subsequent descriptive analysis. Results: There were a total of 317 cases, and 299 were eligible for the study. The mean age at diagnosis was 54.2 years, and 36.1% of the patients were under 50 years old at diagnosis. Positive family history was found in 17.0% of the patients. The diagnosis was made by clinical alteration detected on physical examination in 71.5% of cases, and lump was the most frequent type of lesion (89.0%). Invasive carcinoma was 93.1% of the cases, and the mean tumor size was 28.6 mm. The average time between first medical appointment and diagnosis was 63.2 days, and between diagnosis and beginning of treatment was 39.6 days. Conclusions: This study showed that a significant number of cases occurred in women outside the recommended age for screening in Brazil. Diagnosis was predominantly performed by clinical examination, with delays in obtaining the histological diagnosis, and the stage at diagnosis was high, and these facts were associated with the health system limitations. KEYWORDS: breast neoplasm; age groups; cancer screening.

The economy of the State of Minas Gerais (BR) in a changing world: Technological gap and recente dilemas

Resumo O objetivo deste artigo é analisar as implicações para a economia mineira de sua especialização em commodities e produtos de baixa intensidade tecnológica, tendo como pano de fundo um contexto internacional em rápida transformação produtiva. Para tanto, com base na apresentação das características da economia mineira a partir dos anos 2000, testamos a hipótese de que empresas e setores de maior intensidade tecnológica têm a capacidade de dinamizar a economia do estado de forma mais efetiva, fundamentando-nos na premissa de que essas empresas geram uma massa salarial mais elevada do que aquelas ligadas a outras atividades econômicas. O modelo econométrico testado reforça e confirma a hipótese de que as firmas com maior intensidade tecnológica pagam um prêmio salarial mais elevado, induzindo um efeito positivo na atividade econômica em geral. A base de dados utilizada e o período analisado para a economia mineira, salvo melhor juízo, não foram ainda testados.

The train and the "Spanish señorita":the flu epidemic in Diamantina, 1918

The article analyzes the influenza epidemic in 1918 in Diamantina, a town in the Brazilian state of Minas Gerais. Bibliographic and documental sources are used to investigate the influence of the Vitória-Minas railroad (Estrada de Ferro Vitória a Minas), opened in 1914, on the arrival of the disease in the town, which had until then been represented in the discourse of its elites as insalubrious and isolated. The interrelations between the spread of transportation systems across Brazil, the environment, scientific knowledge, and health-disease processes are discussed.

Knowledge production and innovation: the potential of local universities to create technology-based companies in the Brazilian State of Minas Gerais

This paper analyses the effects of the human capital (university researchers and graduate students) and the knowledge assets (academic publications, academic patent petitions and postgrad scholarship numbers) of the universities of Minas Gerais State, Brazil, on the creation of technology-based companies (TBCs) in its 12 mesoregions. Based on the InovaData-MG TBC census and open government data from the years 2000 to 2017, this study seeks to outline a knowledge production function for the Minas Gerais ecosystem and explore possible divergences in the innovation potential of its mesoregions. The negative binomial regression model was used to test hypotheses using variables from the state's mesoregions that quantify the human capital characteristics that generate research and its knowledge assets to assess their influence on the new TBC creation. The data analysis methodology has an explanatory and predictive character which made it possible to verify part of the proposed empirical model's validity. The results of this work confirm that human capital of universities and region maturity positively influences the average propensity to create new TBC.

Informação e memória, biblioteca e memória o caso EMATER/MG

The treatment and preparation of a collection for a new destination after the closure of a library is a subject under explored in research and an activity for which there are no prepared instruments. This was the challenge of an action at the Nilza TavaresDias library of the Technical Assistance and Rural Extension Company of the State of Minas Gerais (EMATER-MG), in Brazil, deactivated in 2018. Since 2020, the inventory work for the proper disposal of the collection was started. For this purpose, it was necessary to develop the work methodology, as its base for recording and physical restructuring of the library for the activities’development. During the process, a large quantity/quality of EMATER publications produced since its creation was found, thus arising the need for a more depth study of these materials as an information, documentary and institutional memory source.
