Abstract Aimed to map the instruments used in evaluating Burnout syndrome in public security professionals, indicating the psychometric aspects, samples, and associated variables. Nineteen studies were selected from the searched databases (PsycINFO, PubMED and Google Scholar). Results indicated that the instruments MBI-GS, MBI-HSS, BM-S, CBI and CESQT, but only one of the instruments showed evidence of validity in this context. Burnout was associated with personal, organizational, and specific variables. Comparison of studies and Burnout indices was limited due to the lack of standardization. The absence of evidence of validity and standardization of results leads to problems such as the lack of empirical support for the scores and difficulty in comparing studies. The data reveal limitations in the assessment of burnout levels used in the context of public safety, as the measures do not present validity evidence for this context, pointing to the need for research in the area.

Resumen El objetivo fue mapear los instrumentos utilizados en la evaluación del síndrome de Burnout en profesionales de la seguridad pública, indicando los aspectos psicométricos, muestras y variables asociadas. Se seleccionaron diecinueve estudios de las bases de datos buscadas (PsycINFO, PubMED y Google Scholar). Los resultados indicaron el uso de los instrumentos MBI-GS, MBI-HSS, BM-S, CBI y CESQT, pero solo uno de los instrumentos mostró evidencia de validez en este contexto. El Burnout se encuentra asociado con variables personales, organizacionales y específicas. La comparación de estudios e índices fue limitada debido a la falta de estandarización. La ausencia de evidencia de validez y estandarización de resultados conduce a problemas como la falta de soporte empírico para las puntuaciones y la dificultad para comparar estudios. Los datos revelan limitaciones en la evaluación de los niveles de burnout utilizados en el contexto de la seguridad pública, ya que las medidas no presentan evidencia de validez para este contexto, lo que apunta a la necesidad de realizar investigaciones en el área.

Abstract The human oral cavity is colonized by a diversity of microorganisms living harmoniously. When an imbalance occurs in this population, also called dysbiosis, opportunistic microorganisms lead to oral infections. Nystatin, a traditional antifungal, and red propolis, a resinous mixture collected by honeybees from plant source, can be used to control oral infections. Using β-cyclodextrin (βCD) inclusion complexes with nystatin and red propolis may improve the solubility, stability and antimicrobial activity of these substances, making it possible to include these complexes in pharmaceutical formulations. This study aimed to obtain these inclusion complexes by solubilization and characterize and evaluate their antimicrobial activity against microorganisms from the oral cavity. The inclusion complexes showed loss of crystallinity and the infrared spectra showed interactions between the substances. The content of total polyphenol ranged from 4.32-4.62 mg/g, while the content of flavonoids was between 3.05-3.83 mg/g. The red propolis (Prop):βCD(1:1 and 2:1) complexes were the most active against S.aureus, S.epidermidis, S.mutans and C.albicans with Minimum Inhibitory Concentration (MIC) ranging between 32-256 µg/mL. The inclusion complex of nystatin (Nys):βCD(1:1) effectively inhibited C.albicans growth (MIC=4µg/mL). Interestingly, the association between Nys:βCD(1:1) and Prop:βCD(1:1 or 2:1) showed a synergic effect, improving antifungal activity when compared to red propolis complex alone.

RESUMO O desenvolvimento de novos compósitos oxalato de zinco (ZnC2O4)/xerogel de carbono para aplicações fotocatalíticas foi avaliado. O uso do xerogel de carbono é justificado por sua alta condutividade, que facilita a separação de cargas geradas na estrutura do oxalato de zinco. A eficiência fotocatalítica dos materiais foi avaliada pela decomposição do azul de metileno. Os materiais foram produzidos pela dispersão do oxalato de zinco em gel de carbono, durante sua policondensação em meio ácido. Os difratogramas de raios-X evidenciam a existência da fase ?-ZnC2O4 no compósito desenvolvido. O material apresenta significativa absorção de radiação na faixa de comprimentos de onda visível. O compósito apresentou degradação completa do azul de metileno (10 mg L-1, 0.5 L) no sistema após 3 h sob luz solar simulada, com dosagem de 50 mg L-1 de catalisador, evidenciando o potencial uso desse material em processos de tratamento de efluentes.

ABSTRACT The development of new ZnC2O4/carbon xerogel composites for photocatalytic applications has been evaluated. The use of carbon xerogel is justified by its high conductivity, which facilitates the separation of charges generated in the structure of zinc oxalate. The photocatalytic efficiency of the materials was evaluated by the decomposition of methylene blue. The materials were produced by dispersing zinc oxalate in carbon gel during its polycondensation in acidic medium. X-ray diffractograms show the existence of the ?-ZnC2O4 phase in the developed composite. The material has significant radiation absorption in the visible wavelength range. The composite showed complete degradation of methylene blue (10 mg L-1, 0.5 L) in the system after 3 h under simulated sunlight, with 50 mg L-1 catalyst dosage, showing the potential use of this material in treatment processes. of effluents.

ABSTRACT Objective: To describe the characteristics of the heel prick test in newborns admitted to the intensive care unit of a university hospital as well as to determine whether maternal and fetal conditions could have affected the results of this test. Methods: Retrospective longitudinal study with a quantitative approach that evaluated 240 medical records. The data collected were analyzed by descriptive statistical analysis. Results: There was a predominance of pregnant women aged 20 to 34 years who had a complete secondary education and who had more than six prenatal care visits. Maternal complications or pathologies occurred in 60% of the mothers, and most (67.5%) did not present any condition that could have affected the heel prick test results. Most newborns were premature and exhibited low birth weight. Approximately 90% of newborns exhibited conditions that could have influenced the test, especially prematurity, parenteral nutrition and blood transfusion. Of the 240 newborns, 25% had abnormal heel prick test results, especially for cystic fibrosis and congenital adrenal hyperplasia. Conclusion: There are maternal and neonatal conditions that can affect heel prick test results, and therefore, their investigation is essential, aiming to guide measures that promote mother and child health and consolidate neonatal screening in this population.

Hybrid inorganic-organic solar cells are an attractive alternative energy source because of their low-cost production and ability to make use of a large amount of solar radiation available. This work aims to evaluate different solar cells composed of TiO2 and ZnO with P3OT/P3MT copolymer. Layers of semiconductor oxides were deposited on transparent fluorine-doped tin oxide (FTO) by spin coating and adsorption in the polymer solution. X-ray diffraction (XRD), scanning electron microscopy (SEM), were used to characterize the fabricated semiconductors and curves of current density vs. potential (j-V), photochronoamperometry (j-t) and electrochemical impedance spectroscopy (EIS) were used to determine their electrical characteristics. The XRD analyses confirmed the crystalline nature of the oxide materials. SEM micrographs showed the spherical morphology of ZnO and the poorly defined agglomerate morphology of TiO2. The electrochemical measurements proved that the best cell was produced with P3OT/P3MT copolymer and TiO2, owing to its lower charge transfer resistance, with the following photovoltaic parameters: Voc = 0.615 V ± 0.004, jsc = 1.545 mA cm-2 ± 0.240, FF = 0.637 ± 0.003, and η = 0.617% ± 0.117.

Hybrid solar cells show an increasing number in researches due to its low cost and easy of production. They are composed by and organic material and a semiconductor oxide. The aim of this paper was to synthesis and characterize zinc oxide by coprecipitation and apply it in a hybrid solar cell that uses a P3HT/P3OT copolymer as charge carrier. The cell was assembled in "sandwich" form using FTO/ZnO/P3HT-P3OT as work electrode, (Pt/FTO) as conter electrode and I/I-3 redox couple as electrolyte. Through the X-ray diffractogram the formation of a single ZnO wutzite hexagonal phase was observed. The morphology obtained for the oxide was spherical. The results of photochronoamperometry showed current density values of jP3HT/P3OT =0.55 mA.cm-2 for the cell in the presence of the copolymer and the curve jxV showed an efficiency of 0.16% for the studied cell, demonstrating that the polymer was a satisfactory sensitizer.

Dye-sensitized solar cells (DSSC) have received much attention as an alternative to silicon-based solar cells, due to various advantages. Zinc oxide (ZnO) is an n-type semiconductor employed as photoanode on DSSC. The decrease of charge recombination is an efficient strategy capable of improving the photovoltaic performance of the device. In this perspective, Nb2O5 was added on ZnO solar cells. The oxides were characterized by the X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR) and X-ray fluorescence (XRF). The photovoltaic parameters were obtained through J-V plots and photocronoamperometry. The results showed that the niobium oxide obtained presented orthorhombic crystal structure and DSSC with the addition of niobium oxide showed better efficiency, of 1.42% when compared the device with only ZnO.

Abstract This work aimed to characterize mortality by sickle cell disease in Brazil. The MEDLINE electronic database was searched using the terms ‘mortality' and ‘sickle cell disease' and ‘Brazil' for articles published in the last five years aiming to provide a current analysis of the subject in question. Eight studies on mortality by sickle cell disease were carried out in the Brazilian states of Maranhão, Bahia, Minas Gerais, Rio de Janeiro and Mato Grosso do Sul. The majority of the deaths occurred in patients with sickle cell anemia, which is the most common genotype and causes the most severe clinical manifestation of the disease. In summary, there are few published studies on mortality related to sickle cell disease in Brazil, and most are from the state of Minas Gerais. This study emphasizes the importance of developing more studies on sickle cell disease mortality, so that it may be possible to profile gene carriers and give health professionals more data to strategize the delivery of more effective assistance to these individuals. Despite the early diagnosis of sickle cell disease by the Neonatal Screening Program and the use of preventive and therapeutic measures (penicillin, immunization and hydroxyurea), mortality by sickle cell disease on the world stage is still significant.

RESUMO. Objetivou-se avaliar a relação entre os atributos físicos do solo e do relevo com as áreas suscetíveis ao deslizamento de terra na sub-bacia do Córrego do Yung, localizada no bairro Três Moinhos em Juiz de Fora, Minas Gerais. Foram locados os pontos de amostragem e procedeu-se às medições da profundidade do solum e coleta de material subsuperficial, observando-se dois fatores: granulometria e tipo de horizonte. Foram determinadas, em laboratório, a condutividade hidráulica, densidade do solo e de partículas, porosidade total, macroporosidade e microporosidade. Realizaram-se as interpolações para predizer e mapear os valores dos atributos físicos em toda a sub-bacia hidrográfica. De acordo com os mapas temáticos, a textura argilosa relacionou-se à maior condutividade hidráulica, maior porosidade total e menor densidade do solo. Nas áreas mais íngremes, foram mapeados maiores teores de silte em profundidade, representando a pequena espessura do horizonte B. Verificou-se estreita relação da curvatura com a espessura do solo, sendo os mais profundos localizados em áreas planas e de menor declividade. Quanto às análises geoestatísticas, os valores de alcance para os atributos macroporosidade, microporosidade e silte em profundidade revelaram os menores valores encontrados, o que evidencia o conhecimento da baixa continuidade estrutural do solo em áreas potencialmente erodíveis.

ABSTRACT. The present study aimed to evaluate the relationship between the physical properties of the soil and relief in areas that are susceptible to landslides in the sub-basin of the Córrego do Yung, a creek in the urban district Três Moinhos of Juiz de Fora, Minas Gerais. Depth measurements of the solum were made at the soil sampling points, and the subsurface material was collected and analyzed for the two factors of particle size and type of horizon. In the laboratory, we determined the hydraulic conductivity, bulk and particle density, and total porosity, macroporosity and microporosity. The values of the physical properties throughout the sub-basin were predicted and mapped. Thematic maps were generated and showed a relation to each other: the clay was related to a higher hydraulic conductivity, higher porosity and lower soil density. In the steeper areas, the greater silt contents were mapped in the deeper layers and indicated the thin thickness of horizon B in these areas. A close relation of the curvature with the soil thickness was detected and was greater in the flat areas with less slope. The geostatistical analysis showed that the range of values for the properties of macroporosity, microporosity and silt was the lowest in the deeper layers, indicating low structural continuity in potentially erodible areas.

The experiment was carried out to evaluate the influence of nutritional correction on the partial diet replacement or pure-food methodology to determine the energy values (apparent metabolizable energy - AME and nitrogen-correct apparent metabolizable energy - AMEn) and coefficient of metabolizability of nutrients of maize. The method of total excreta collection was used, with 120 female Cobb 500® broilers weighing 1,339±3 g and at 28 days of age distributed in a completely randomized design with five replicates and four birds per experimental unit. The treatments were pure maize with three levels of nutritional correction (0, 50 and 100%) and a maize-replaced basal diet (400 g/kg) with two levels of correction (0 and 100%). The corrections were made in order to meet the nutritional requirements of calcium, available phosphorus and sodium yonder trace minerals, vitamins, choline, lysine, methionine + cystine, threonine and tryptophan. The AME and AMEn of maize and coefficient of metabolizability of dry matter were higher when correction at 100% was made, regardless of the methodology used (pure feed or replaced basal diet). The correction at 50% of nutrients increased the coefficient of metabolizability of crude protein in pure maize when compared with 0 or 100% of correction. The values determined with pure maize were lower than those determined with the method of partial replacement. The absence of nutritional correction underestimates the energy values and metabolizability of nutrients from maize.
