ABSTRACT Objective: To characterize the environmental factors of children and adolescents with Cerebral Palsy (CP) in the state of Minas Gerais (MG), Brazil. Methods: This is a cross-sectional study involving 164 caregivers of children/adolescents with CP, aged 1-14 years. The Gross Motor Function Classification System (GMFCS) and the Manual Ability Classification System (MACS) were used to classify the participants’ functioning, and environmental factors were evaluated by an on-line questionnaire that examined products and technologies, physical environment, services, and systems. A descriptive analysis was performed using percentage and frequency. Results: Most participants had bilateral CP (66.9%) and 45% of them were spastic. Levels II and V of the GMFCS and MACS were the most frequent. About half (49.4%) used anticonvulsants, 27.4% underwent botulinum toxin application, and 29% went through orthopedic surgery in the lower limbs. Among the participants, 71.3% used orthoses in the lower limbs, and 51.8% used the public health care system. Most had access to physiotherapy (91.5%), but found difficulties to access interventions with other professionals, such as psychologists (28%) and nutritionists (37.8%). The school was the most frequently adapted environment (78%), and had the highest level of structural adaptation (42.7%). Conclusions: The results of this study suggest that the barriers to access health services and barriers to the physical environment may impact participation and social inclusion.

RESUMO O objetivo do estudo foi identificar desigualdades macrorregionais relacionadas à estrutura e ao processo de trabalho para o atendimento do Diabetes Mellitus (DM) na Atenção Primária à Saúde (APS) ao longo dos três ciclos do Programa Nacional de Melhoria do Acesso e da Qualidade da Atenção Básica (PMAQ-AB) no Brasil. Trata-se de um estudo ecológico, longitudinal, de abrangência nacional, com dados secundários dos três ciclos do PMAQ-AB. Os dados foram comparados entre as macrorregiões brasileiras utilizando o teste t com a correção de Bonferroni. As regiões Norte e Nordeste apresentaram os menores percentuais de adequação nos itens de estrutura: dependências da unidade (<74%), acessibilidade ao cadeirante (<63%), horário especial de funcionamento (<16%), equipe ampliada (<12%) e insumos (<89%) em todos os ciclos do PMAQ-AB, quando comparadas às demais regiões. Já os itens relacionados ao processo de trabalho apresentaram pouca variação entre as regiões, e os que apresentaram percentuais médios ≤ 75% de adequação foram: agenda especializada (41%, 33%, 41%), apoio matricial (58%, 72%, 70%), oferta e resolubilidade de ações (62%, 64%, 75%) e educação permanente (35%, 42%, 58%). Ainda existe a necessidade de investimentos na estrutura e em melhorias no processo de trabalho das equipes, principalmente nas macrorregiões Norte e Nordeste.

ABSTRACT This study aimed to identify macro-regional structure and work process inequalities for Diabetes Mellitus (DM) treatment in Primary Health Care (PHC) throughout the three cycles of the National Program for Access and Quality Improvement of Primary Care (PMAQ-AB) in Brazil. This ecological, longitudinal, nationwide study employed secondary data from the three PMAQ-AB cycles. The data were compared between the Brazilian macro-regions using the t-test with Bonferroni correction. The North and Northeast had the lowest percentages of adequacy in the structure items: unit premises (<74%), wheelchair user accessibility (<63%), special opening hours (<16%), expanded teams (<12%), and supplies (<89%) in all PMAQ-AB cycles when compared to other regions. The items related to the work process barely varied between regions, and those with mean adequacy percentages ≤ 75% were specialized agenda (41%, 33%, 41%), matrix support (58%, 72%, 70 %), offer and resolution of actions (62%, 64%, 75%) and continuing education (35%, 42%, 58%). Investments are still required in the structure and improvement in the teams’ work process, especially in the North and Northeast macro-regions.

Resumo Objetivou-se analisar a correlação da qualidade dos serviços da Atenção Primária na redução da mortalidade infantil, através do geoprocessamento. Um estudo ecológico, de abordagem transversal, em que foram utilizados dados secundários de todos os 5.565 municípios brasileiros para análise da taxa de mortalidade infantil (TMI) e causa de óbito infantil. Os dados da TMI foram obtidos no Sistema de Informação de Mortalidade. Para a análise espacial, incluímos 5.011 municípios. As análises de clusterização ocorreram no software GEODA e as análises de regressão espacial no ARCGIS 10.5. No Brasil houve uma redução de 45,07% da TMI entre os anos 2000 e 2015. A maior redução ocorreu na região nordeste do país, apesar de ainda ser a região com maior número na TMI. Dos 749 municípios analisados no cluster diferencial para óbito infantil, 153 apresentaram alta TMI. As áreas com maior expansão de alta TMI foram encontradas nas regiões Norte e Nordeste. No Brasil, a TMI mostrou-se inversamente associada à acessibilidade aos serviços de alta complexidade, ao estrato da gestão em saúde e porte populacional, à referência para o parto, à taxa de nascidos vivos, à renda per capita e à taxa de desemprego. Verificou-se uma crescente redução da TMI entre o período de 2000 a 2015.

Abstract This study sought to analyze the correlation of the quality of Primary Health Care services in reducing child mortality, via geoprocessing. It involved an ecological study, with a cross-sectional approach, in which secondary data from all 5,565 Brazilian municipalities were used to analyze the infant mortality rate (IMR) and cause of infant death. The data related to IMR was obtained from the Mortality Information System. For the spatial analysis, 5,011 municipalities were included. The clustering analyses were performed using GEODA software and the spatial regression analyses were performed using ARCGIS 10.5 software. In Brazil, there was a 45.07% reduction in IMR between the years 2000 and 2015. The greatest reduction occurred in the northeastern region of the country, although it is still the region with the highest IMR. Of the 749 municipalities analyzed in the differential cluster for infant death, 153 had high IMR. The areas with the greatest increase in IMR were found in the North and Northeast regions. In Brazil, IMR proved to be inversely associated with the accessibility to high complexity services, health management strata and population size, reference for childbirth, live birth rate, per capita income and unemployment rate. A progressive reduction in IMR was recorded between 2000 and 2015.

Background: A population study is an important tool that can be used to understand the actual epidemiological scenario of the Covid-19 in different territories, identify its magnitude, understand its transmission dynamics, and its demographic, geographical, and social distribution. Objective: The aim of this study was to determine the prevalence and dynamics of SARS-CoV-2 infection in the population of two Brazilian cities during the pandemic first wave and subsequent socioeconomic and health effects. Materials &amp; methods: This paper described the methodological procedures adopted and the prevalence of the SARS-CoV-2 infection in the population. A household survey was conducted between October and December 2020, in two historic cities of Brazil's mining region. Anti-SARS-CoV-2 antibody was detected using the Wondfo® rapid test. The face-to-face interview consisted of administration of a questionnaire containing registration data, sociodemographic and economic variables, living habits, general health condition, mental health, sleep habits, and eating and nutrition. Results: We evaluated 1,762 residents, of which 764 (43.4%) were in Mariana and 998 (56.6%) in Ouro Preto. For both cities, 51.9% of the interviewees were female, with a predominance of the age range 35 to 59 years old (47.2%). The prevalence of the SARS-CoV-2 infection was 5.5% in all cities, 6.2% in Ouro Preto, and 4.7% in Mariana. The prevalence was similar between cities (P&gt;0.05). Conclusion: The study was effective in verifying the seroprevalence of infection by the virus and its findings will enable further analyses of the health conditions of the population related to social isolation and the risk of infection with SARS-CoV-2.

ABSTRACT The inclusion of pulse flours with higher dietary fiber content in bakery products, such as chickpea (Cicer arietinum L) flour, has been exploited by the food industry due to its nutritional and sensory characteristics. This work aimed to develop a sandwich bread with a partial substitution (7.5%, 15%, and 30%) of refined wheat flour by whole chickpea flour (WCF) and also to evaluate the effects on sensory acceptance, physicochemical parameters, and texture profile during the shelf life. Four methods for obtaining WCF were assessed and the best condition was used to produce the sandwich bread. Sensory evaluation was carried out with 65 consumers using a 9-point hedonic scale and a purchase intention scale. Firmness, elasticity, cohesiveness, chewability, and fracturability was evaluated by the Texture Profile Analysis (TPA). The specific volume, total fungi count, pH, titratable acidity, and moisture content were also determined. The nutritional composition was estimated by mass balance. Data demonstrated that there was no difference (p>0.05) in sensory evaluation of the products elaborated with different concentrations of WCF, and all samples presented good acceptance. The addition of WCF did not cause negative effects on the texture and volume characteristics of the bread. The sample with 30% WCF had adequate technological characteristics, resulting in a product with higher nutritional value, especially dietary fiber, and was well accepted by the consumers. This formulation can be used by the food industry and also in domestic preparations, contributing to the diversification and nutritional enrichment of sandwich bread.

RESUMEN La inclusión de harinas de granos no convencionales con mayor contenido de fibra dietética en productos de panadería, como la harina integral de garbanzo (HIG) (Cicer arietinum L), es utilizada por la industria alimentaria debido a sus características nutricionales y sensoriales. Este trabajo tuvo como objetivo desarrollar un pan para sándwich (PPS) con sustitución parcial (7.5%, 15% y 30%) de harina de trigo refinada por HIG así como evaluar la aceptación sensorial, parámetros fisicoquímicos y el perfil de textura durante su vida útil. Fueron evaluados cuatro métodos para la obtención de HIG, utilizándose la mejor condición para producir el PPS. Sesenta y cinco consumidores realizaron la evaluación de aceptación sensorial e intención de compra con una escala hedónica de 9 puntos. La firmeza, la elasticidad, la cohesión, la masticabilidad y la fracturabilidad se evaluaron mediante el análisis de perfil de textura (TPA). También se determinó el volumen específico, el recuento total de hongos, el pH, la acidez titulable y el contenido de humedad. La composición nutricional se estimó por balance de masa. Todas las muestras presentaron buena aceptabilidad sin diferencias estadística. La adición de HIG no causó efectos negativos en la textura ni el volumen del PPS. La muestra con 30% de HIG tubo características tecnológicas adecuadas, resultando en un producto con mayor valor nutricional, especialmente por la fibra dietética. Esta formulación podría ser utilizada por la industria alimentaria y también en preparaciones domésticas, contribuyendo a la diversificación y al enriquecimiento nutricional del pan para sándwich.

Abstract The origin of the soft ore at the S11D iron mine in Carajás was investigated using 20 samples from a diamond drill hole. The methods of analyses were X-ray diffraction (XRD), optical microscopy, whole-rock chemistry, and scanning electron microscope coupled with energy-dispersive X-ray spectroscopy (SEM/EDS). The drill hole presents a profile through the substratum (protore, a banded iron formation - BIF) and three weathering horizons, defined from the base to the top, saprolite (coarse and fine), and crust. The soft iron ore occurs distributed along the saprolite horizon, and it is composed mainly of hematite and subordinate magnetite. The amount of quartz decreases upwards, whereas the amount of Fe-Al-(Ti-P)-minerals increases towards the top. The total iron is enriched in the fine saprolite when compared to the protore (42.55 to 97.62 wt.% Fe2O3, respectively). Trace elements such as Zr, Cr, Y, and rare earth elements (REE) show relative enrichment upward because they are generally located in residual minerals (as zircon and anatase). The REEs in iron ore samples exhibit enrichment of light rare earth elements (LREE) and depletion of heavy rare earth elements (HREE), with pronounced positive Eu anomaly, which reaffirms the connection between iron ore and BIF. Based on the mineralogy, chemistry, textures, and structures, a genetic laterite-supergene model is proposed for the origin of soft ore at the S11D deposit.

Abstract INTRODUCTION Tuberculosis (TB) is an infectious and contagious disease caused by Mycobacterium tuberculosis. TB emerged in the 21st century as an unsolved public health problem. This study aimed to analyze the relationship between the characteristics of basic health units (BHUs) and the number of TB cases detected in Maranhão, Brazil. METHODS An ecological, analytical study was conducted using the municipalities in the state of Maranhão as the unit of analysis. Data regarding the number of detected TB cases was obtained from the Sistema de Informação de Agravos de Notificação database, and the characteristics of the BHUs were obtained from the first cycle of data collection for the Program to Improve Access and Quality of Basic Care. The BHU structure was classified as adequate (80%-100%), partially adequate (60%-79%), poorly adequate (40%-59%), or inadequate (<40%) according to the presence of specified items. The number of BHUs per municipality in each adequacy category was estimated. Inflated Poisson regression analysis was performed to estimate the incidence density ratios (IDRs) and the 95% confidence intervals (95% CIs). RESULTS Municipalities with a higher level of BHU adequacy had a higher number of detected TB cases (IDR = 1.61, 95% CI: 1.01-2.60). CONCLUSIONS Better structured health services in primary care may be associated with better detection and/or notification of TB cases.

Resumo Neste estudo, compósitos de MnO2-levedura de pão, produzidos pela oxidação direta da levedura com KMnO4 sob condições ácidas, foram usados como biossorvente para remover o corante trifenilmetano verde Malaquita (VM) de solução aquosa. Os parâmetros que influenciam o processo de adsorção tais como pH, tempo de contato, temperatura, concentração inicial do corante e concentração do biossorvente foram avaliados em experimentos de bancada. As condições ótimas de descoloração foram observadas em pH 10 e concentração de biomassa igual a 1,0 g L-1. Os resultados de remoção do corante foram ajustados ao modelo cinético de pseudo segunda ordem. O processo de adsorção foi descrito pelo modelo isotérmico de Langmuir e a capacidade máxima de biossorção foi estimada em 243,9 mg g-1 (na temperatura de 25°C). Os valores negativos de ∆G° e valores positivos de ∆H° indicaram que a biossorção do VM pelo compósito MnO2-levedura é espontâneo e endotérmico. A técnica de espectroscopia no infravermelho com transformada de Fourier indicou que nanopartículas de MnO2 depositadas na superfície do compósito MnO2-levedura facilitaram a adsorção do VM. Concluiu-se que o compósito MnO2-levedura de pão possui potencial para ser usado como adsorvente na remoção de VM de solução aquosa.

Abstract In this study, baker’s yeast-MnO2 composites, produced by direct oxidation of yeast with KMnO4 under acidic conditions, were used as biosorbent to remove the triphenylmethane dye Malachite green (MG) from an aqueous solution. Parameters that influence the adsorption process, such as pH, contact time, temperature, initial dye concentration and biosorbent dosage, were evaluated in batch experiments. The optimum removal of MG was found to be 86.7 mg g-1 at pH 10, 1.0 g L-1 of biomass dosage and 45°C. The kinetic data of dye removal was better described by the pseudo-second-order model. The adsorption process followed the Langmuir isotherm model and the maximum biosorption capacity was estimated to be 243.9 mg g-1 (at 25°C). The negative values of ∆G° and the positive value of ∆H° indicated that the MG biosorption onto yeast-MnO2 composites is spontaneous and endothermic. Fourier transform infrared spectroscopy (FTIR) indicated that the nano-MnO2 particles deposited on yeast-MnO2 composites surface facilitated the MG adsorption. It was concluded that baker’s yeast-MnO2 composites have potential for application as adsorbent for removal of MG from aqueous solution.

Introduction: The role of the fatty acid in the prevention or progression of chronic diseases has generated significant interest on the part of researchers. Thus, our objective was to evaluate the long-term effects of high-fat diet containing soybean or canola oil on body development and bone parameters of male rats. Methods: After weaning, rats were grouped and fed either a control diet (7S) or a high-fat diet containing soybean (19S) or canola oil (19C). Femur and lumbar vertebra (LV4) structure were determined at 180 days by dual-energy X-ray absorptiometry and computed tomography. Results: The groups showed similar food intake, body mass and length development. The bone parameters of the 19C were similar to the control group, while the 19S showed lower bone parameters when compared to the other groups. Conclusions: The high-fat diet containing soybean oil was unfavorable to bone structure, while the canola oil contributed bone health during the adult stage of life.
