TLR3 and TLR7 prognostic role in early pediatric rotavirus infection
Authors: Gorbunov Sergey G. , Mazankova Ludmila N. , Os'kin Alexandr N.
Published: November 2023

Introduction. Rotavirus infection is an urgent problem for pediatric infectology. The disease does not always proceed smoothly, it is assumed that TLR3 and TLR7 play an important role in its prognosis. The initial number of cells expressing such receptors in early children can probably be considered a predictor of unfavorable course and outcomes of rotavirus infection.
Materials and methods. Infants with rotavirus infection were divided into groups depending on the initial count of TLR3- and TLR7-expressing immunocompetent cells. All patients were examined using general clinical methods. Rotavirus infection was diagnosed by molecular genetic (RNA detected by PCR) and immunochromatographic (determination of antigen) method. Parameters of cellular immunity were assessed by flow cytometry. Statistical data processing was carried out using the Statistica 8.0 program for independent samples using the nonparametric MannWhitney criterion and the Pearson criterion c2.
Results. It was found that in patients with an initially small vs. high count of TLR3-expressing cells, the symptoms of exicosis were observed significantly longer, which determined a significantly longer infusion rehydration therapy. In patients with an initially small count of TLR7-expressing cells, no significant differences were observed during disease course. However, only this group similar to infants with a small count of TLR3-expressing cells were treated with antibiotics due to concomitant bacterial infections. Only convalescents with small count of simultaneously TLR3- and TLR7-expressing cells had repeated episodes of ARI and allergic diseases in catamnesis, whereas infants with extremely low count of TLR3-expressing cells developed additionally an unfavorable outcome such as reactive pancreatopathy.
Conclusion. The initially low count of TLR3- and TLR7-expressing immunocompetent cells leads to a more severe course of rotavirus infection in infants requiring adjusted therapy by introducing antibacterial drugs and in some cases also contributes to arising adverse outcomes and consequences in 612 month catamnesis.

Authors:   Prince Mohammad Bin Fahd University (Kingdom of Saudi Arabia), Wolny-Abouelwafa Edyta
Published: November 2023

In 2019, half a million people all over the world died as a result of drug abuse. This topic is a very sensitive issue in a number of countries, including the Arab Republic of Egypt, where the government informs its citizens every few months about steps to take to combat this problem. Creating a TV series to be aired during Ramaḍān, the most important part of year from the Islamic point of view and also because of the media industry, is one of the tools to create awareness of the danger of drug addiction. In the article, the results of the research conducted on a very popular Ramaḍān TV series from 2015 entitled Taḥt as-Sayṭara are presented. The research focused on the presentation of this problem, in particular whether or not the problem was presented in a realistic way, thus aiding in the fight with drug addiction. This series was special, as it was the first and the only which was devoted so directly to the problem of drug addiction; the sickness covered about 89‒90% of the plot.
The Underpinning Determinants of Voting Behavior: The Case of Sudan
Authors:   Omdurman Islamic University (Sudan), Musa Abdu Mukhtar
Published: November 2023

This article tries to examine the underpinning determinants of voting behavior in Sudan. It adopts a descriptive method and an inter-disciplinary approach with empirical explanation to verify the hypothesis that “voting behavior in Sudan is a function of religious sectarianism and ethnicity more than other determinants, such as ideology, class or socio-economic status.” It discusses the interrelationship between voting behavior and other relevant concepts, such as political behavior, electoral behavior, and political culture. It explains how several determinants/factors converge on influencing the voting behavior. The article notes that the vigorous influence of ethnicity and religious sectarianism over the political behavior in Sudan resulted in apparently irrational voting behavior. These two determinants have marked the political behavior in Sudan since it regained independence in 1956. However, the Uprising of 2018 ushered in an emergence of a new conscious generation that might lead to a paradigm shift for political and voting behavior. The article proposes the adoption of Consociational democracy with proportional representation and parliamentary system to guarantee the representation of minorities and sustain a fair share of power and wealth to put an end to instability and wars. In the case of Sudan, it is advisable that more attention should be paid to the development of political culture and efficacious civic engagement in politics should be boosted to increase conscious political participation to pave the way for sustainable democracy.

RESUMO Introdução: o treinamento em situações críticas em Cirurgia é determinante para o desfecho seguro. O uso de simuladores é bastante consolidado, embora muitos apresentem custos muito elevados, sendo necessária a busca de soluções financeiramente viáveis para os centros de treinamento. Métodos: construímos um simulador de sangramento intra-abdominal de baixo custo com materiais simples como tronco de manequim, tubos de látex, borracha de silicone e tecido impermeável, buscando representar vísceras abdominais e vasos e suas correlações anatômicas. Um sistema de tubos e equipos de soro permitiu o fluxo, sob pressão, de sangue simulado, que vertia livremente durante a simulação. Após a obtenção de modelo funcional, selecionamos cirurgiões gerais para a validação do simulador e seu uso no ensino de Cirurgia. Utilizamos o Índice de Validação de Concordância (IVC), com corte de 0,9. Resultados: a construção do protótipo resultou em gasto de US$71,00 em valores de 2021, destinados à aquisição dos diversos materiais necessários. Doze avaliadores participaram dos testes de validação. Os resultados obtidos dos questionários demonstraram uma boa avaliação em todos os itens, destacando-se o reconhecimento do vaso traumatizado, o acesso à lesão vascular, o controle hemostático por pressão direta assim como por sutura direta da lesão. Conclusão: o simulador proposto obteve bons resultados em cenários de sangramento abdominal de grandes vasos, assim como o controle hemostático do mesmo por pressão direta e sutura. Mostrou-se ferramenta útil para a adaptação a situações de estresse no treinamento em sangramentos intra-abdominais, além de manter baixo custo de construção.

Published: November 2023

ABSTRACT Background: training in critical surgical situations is crucial for a safe outcome. The use of simulators is well established, although many are quite expensive, requiring the search for financially viable solutions for training centers. Methods: we built a low-cost simulator for intra-abdominal bleeding with inexpensive materials, such as a manikin chest, latex tubes, silicone rubber, and waterproof fabric, seeking to mimic the abdominal viscera and vessels and their anatomical correlations. An IV infusion set allowed simulated blood to flow under pressure, and the blood flowed freely during simulation. After obtaining a functional model, we selected general surgeons to validate the simulator and its use in teaching surgery. We used the content validity index (CVI), with a cutoff of 0.9. Results: the cost of building the prototype was US$71,00 in 2021, accounting for the purchase of the various necessary materials. Twelve raters participated in the validation tests. The results obtained from the feedback survey showed a good evaluation of all items, especially the recognition of the injured vessel, access to the vascular injury, hemostasis by manual compression, and hemostatic suturing. Conclusion: the proposed simulator obtained good results in scenarios of intra-abdominal bleeding from large vessels, as well as for hemostasis by manual compression and suturing. It proved to be a useful tool for training in critical intra- abdominal bleeding situations, while maintaining a low cost of building.

ABSTRACT Objective: to trace the clinical and epidemiological profile of penile cancer in Rio Grande do Norte/Brazil and relate them to data published in the literature. Methods: a cross-sectional study was conducted with 94 patients diagnosed with penile cancer in 2011-2018, treated at the Liga Norte Riograndense Contra o Cancer. Results: all patients were diagnosed with squamous cell carcinoma, mainly aged over 50 years, from the states interior, brown, illiterate, or with incomplete primary education. At diagnosis, 68% of patients were classified as having tumors =T2, and 30% had lymph node involvement. Distant metastases were detected in 2.1% of patients at diagnosis. Most patients received the diagnosis in the initial phase of the disease, but 20.2% were diagnosed in stage IV. Partial penectomy was the most performed surgery, and 10% of patients relapsed, mainly in the lymph nodes (87.5%). The mean follow-up of the patients was 18 months, with an estimated overall survival at five years of 59.1%. However, 25% of patients were followed up for up to 3 months, losing follow-up. Conclusion: the State of Rio Grande do Norte has a high incidence of penile cancer with a high frequency of locally advanced tumors at diagnosis and in younger patients younger than 50. Furthermore, socioeconomic factors interfere with early diagnosis and hinder access to specialized services.
Pemex in the context of the global oil company: investment policy and lessons learned
Authors: SANTOS ANGÉLICA TACUBA
Published: November 2023

ABSTRACT The article analyzes Pemex’s investment policy for the period 1980-2019, based on the management of other oil companies. The central question is whether in the last four decades, it has been convenient for Pemex to be specialized in oil extraction, while other companies focused on the comprehensive development of the supply chain. The answer is negative. The sale of crude oil and the abandonment of refining made Mexico a net importer of fuels, a trend, which, today, is seeking to be reversed, in an environment of a high fiscal burden and high indebtedness of the company.

Resumo: O objetivo do estudo foi analisar a tendência de atividade física dos escolares brasileiros e as associações com variáveis demográficas, socioeconômicas e comportamentais, por meio da Pesquisa Nacional de Saúde do Escolar (PeNSE) em suas quatro edições - 2009, 2012, 2015 e 2019. Foram usados dados dos escolares (13-17 anos) participantes das quatro edições da PeNSE (n = 392.922). Descrevemos o percentual de ativos, a média e valores percentuais da atividade física de intensidade moderada à vigorosa em minutos/semana. A regressão de Poisson foi ajustada para sexo, idade, cor da pele, escore de bens e comportamento sedentário (≥ 2 horas/dia para assistir TV e ≥ 3 horas/dia de tempo sentado). Como limitação, a amostra da PeNSE/2009 refere-se apenas às capitais brasileiras. O percentual de ativos reduziu de 43,1% em 2009 para 18,2% em 2019. A média em atividade física de intensidade moderada à vigorosa da PeNSE/2009 (média = 318,4 minutos/semana; IC95%: 313,4-323,4) reduziu 50% em 2019. Na educação física, a média semanal em atividade física de intensidade moderada à vigorosa das meninas foi menor que 50 minutos, ao passo que a dos meninos foi maior que 60 minutos, nas quatro edições da PeNSE. Ainda, 22,7% das meninas relataram (PeNSE/2019) não ter tido aulas de educação física, enquanto o mesmo é relatado por 19,7% dos meninos. O comportamento sedentário sofreu redução no hábito de assistir TV, porém o tempo sentado aumentou de 50,1% (IC95%: 48,9-51,3) para 54% (IC95%: 53,1-54,9) entre a PeNSE/2009 e a PeNSE/2019. Como consequência da queda nos níveis de atividade física, são necessárias políticas públicas que promovam a atividade física, como aumentar as aulas de educação física na escola para, no mínimo, três vezes por semana.

Resumo: Este estudo buscou analisar a relação entre as hospitalizações por agravos respiratórios e a queima regular da cana-de-açúcar em Pernambuco, Brasil. Trata-se de um estudo ecológico de série temporal correspondente ao período de 2008 a 2018. Foram comparadas as taxas de hospitalizações por agravos respiratórios em crianças menores de 5 anos e em idosos maiores de 60 anos em municípios produtores e não produtores de cana-de-açúcar, por meio da análise estatística não paramétrica de Mann-Whitney. Conjuntamente, foi observada a distribuição mensal das ocorrências de focos de calor nos municípios casos e controles e aplicada a correlação de Pearson para analisar a associação entre ambas as variáveis. Foi verificado que, para ambos os grupos etários, as taxas de hospitalizações são maiores nos municípios produtores de cana-de-açúcar, com diferença estatística significativa p < 0,005. A taxa de internação hospitalar em idosos é 28% mais elevada nos municípios casos, sendo ainda maior em crianças menores de 5 anos, cuja razão das medianas é 40%. No entanto, foi identificado que o comportamento sazonal das hospitalizações por agravos respiratórios diverge do observado na distribuição mensal dos focos de calor, não havendo correlação estatística significativa. Esses achados sugerem possível associação com a exposição crônica aos particulados emitidos pela queima de biomassa, comprometendo a saúde de grupos vulneráveis, e endossam a necessidade de substituição das queimadas no monocultivo da cana-de-açúcar, bem como a estruturação de políticas públicas de proteção à saúde humana e ambiental.

Published: November 2023

Resumo A Literatura Infantil (LI) tem papel importante na formação do sujeito e pode contextualizar aspectos da Educação Ambiental (EA), contribuir para o Letramento Científico (LC) e Alfabetização Científica (AC), pois estimula a criticidade e a reflexão. Na perspectiva de ampliação cultural da criança, acreditamos na possibilidade de buscarmos literaturas que possam auxiliar na iniciação ao processo de LC/AC e EA; no entanto, como saber se aquela ou outra literatura pode ajudar nesse processo? Com essa finalidade, construímos uma Matriz para análise de literatura com esse viés. Entendemos que, ao fazer a análise do texto, o professor consiga reconhecer que, à medida que tenha interesse em estimular a compreensão sobre a Ciência e o reconhecimento dela no meio social, pode se valer do recurso da LI, sem ainda a necessidade do uso didático dela, como uma possibilidade de ampliação do acesso dos alunos à cultura, incluindo a científica.
Gonadal proliferation and reproductive cycle of the exotic sea squirt Cnemidocarpa amphora () (Pleurogona, Styelidae) sampled for the first time from the northern coast of Arabian Gulf in Saudi Arabia
Authors: AlQurashi N. A. , Ibrahim G.
Published: November 2023

Abstract Specimens of Cnemidocarpa amphora were collected monthly from the Arabian Gulf from September 2017 to August 2018. Parts of their gonads were prepared for histological testing. The gonads’ diameters varied by month. Each gonad contained many ovarian follicles with different morphologies and was surrounded by several testicular follicles. The ovarian and testicular follicles were separate, although the latter were always present near the former. Repeated measures ANOVA tests were conducted to investigate monthly changes in oocyte stages. In squirts measuring 12–13 cm in length, the gonads measured 30–50 mm from July to August; 20–25 mm from September to October; 15–20 mm from November to February; and 25–40 mm from March to June. Oogonia budded from the germinal epithelium with diameters of 20–30 µm. Previtellogenic oocytes measuring 70–120 µm were characterized by the deposition of small granules of protein around the nucleus, a continuous layer of follicular cuboidal epithelium, and scattered vacuoles in the ooplasm. The measurement of gonads and oocyte diameters were performed by image analysis (Image scope 2.3, Image Line, Inc.) and stage micrometer. The vitellogenic oocytes measured 130–220 µm and the follicular epithelium consisted of flattened and cuboidal layers. Beneath the vitelline membrane, scattered test cells appeared in the ooplasm and different granules of protein and MPS were deposited in the ooplasm. In the later phase, lipid droplets began to appear in the ooplasm. Yolk bodies formed after the impregnation of various granules together and the oocyte was ready to be shed. Before spawning, a yolk membrane appeared above the ooplasm. Post-vitellogenic oocytes, in which the homogeneity of ooplasm was restored, underwent gradual lysis and entered the atretic phase. Different stages of sperm development were present year-round in different follicles of the same squirt; hence, the testes were always mature.

Abstract The bacaba (Oenocarpus bacaba Mart.) peel corresponds to 15% of the whole fruit and is rich in antioxidants with potential application in product development. In nanotechnology, emulsified formulations such as nanoemulsions stand out for providing modified release and improving the bioavailability of conveyed substances. The aim of this work was to develop nanoemulsified systems from baru oil containing hydroalcoholic extract from the bacaba peel, evaluate their stability and antioxidant potential. After the HLB (Hydrophilic-lipophilic balance) determination of the baru oil, thirty-two formulations were developed, varying the proportions of surfactants, aqueous phase, and baru oil. Of those 32, 16 formed emulsified systems, and the ones with a higher amount of oil (20%) were incorporated with the BPE. The systems were submitted to stability studies to verify their viability. After that, several tests were performed, such as rheological characteristics, hydrodynamic diameter of the droplets, polydispersion index, zeta potential, and antioxidant potential by DPPH and ABTS+ radical scavenging methods. After the studies, two samples remained stable and presented a non-Newtonian pseudoplastic profile with thixotropy, hydrodynamic diameter of less than 200 nm, monodispersity, and negative zeta potential. The BPE showed antioxidant potential, with superior activity when incorporated into the nanoemulsified system. A strong negative correlation was found between the two antioxidant methods, where both demonstrated the same profile of potential antioxidant activity for the extract and formulations. The studied formulation showed that the use of BPE is a viable alternative for the development of new products based on sustainable technologies.
Antibody seroprevalence against canine distemper virus, parvovirus, and adenovirus in dogs from a brazilian animal shelter

Published: November 2023

ABSTRACT This study aimed to identify and compare the seroprevalence for canine distemper virus (CDV), canine parvovirus (CPV), and canine adenovirus (CAV) between newly admitted and already sheltered dogs. 122 dogs over six months of age and unvaccinated upon admission were sampled and divided into two groups: (A) newly admitted dogs and (B) dogs sheltered for at least two months. Sera were collected to determine IgG antibody titers against CDV, CPV, and CAV. We conducted a descriptive analysis of the samples and a chi-square test to investigate the relationship between potential elements associated with protective antibody titers. The results were: 56.5% of the dogs had protective levels of antibodies to all three pathogens. Dogs in group A had lower titers compared to those in group B for all three pathogens, with significant differences for CDV and CAV. We found no significant difference between the proportion of seropositive dogs and their age or reproductive status. The study suggests that the examined pathogens can circulate in the animal shelter and that dogs can be more exposed to these pathogens in the shelter than in the urban environment. Therefore, an effective immunization program should be carried out on all animals upon admission to shelters.

ABSTRACT An accurate diagnostic test for Helicobacter spp. infection in dogs is necessary but no gold standard diagnostic method has yet been established. The purpose of this study was to assess the sensitivity of conventional diagnostic methods as opposed to immunohistochemistry (IHC) in the detection of Helicobacter spp. in gastric samples of dogs with chronic gastropathy. Samples of gastric fundus, body and antrum were collected by gastroscopy from 13 domestic dogs presenting chronic vomit and submitted to the rapid urease test (RUT), cytopathology, histopathology with Hematoxylin-Eosin (HE) and Warthin-Starry (WS) stain, and IHC. Cohen's kappa coefficient was carried out to determine the agreement between techniques compared to IHC. Prevalence of colonization detected by IHC was 92% and was higher in the gastric fundus. The sensitivity of each technique in detecting Helicobacter spp. in the gastric fundus, body, and antrum, respectively, were as follows: RUT 50%, 70%, 17%; cytology 58%; 70%, 50%; HE 42%; 70%, 50%; WS 67%; 80%, 50%. We found that IHC was the most sensitive method for Helicobacter spp. diagnosis revealing that gastric fundus samples have higher presence of bacteria. Squash cytology enhances sensitivity and ancillary staining such as WS should be taken into consideration towards diagnosis.

ABSTRACT KIT protein is associated with the etiology of canine mast cell tumors (MCT); however, the expression patterns of KIT are highly variable. The aim of this study was to determine if KIT patterns are related with eosinophil count in MCT. Hematoxylin eosin and May Grünwald-Giemsa stain techniques were applied, histological grading and eosinophil counting were performed in 48 MCT samples. Immunohistochemical evaluation was performed with IL-5, VEGFr, and c-KIT antibodies. The percentage of immunolabeling with IL-5 and VEGFr was determined, and the samples incubated with c-KIT were graded according to the immunolabeling pattern. Comparison of the mean eosinophil count between the histological grades and the different KIT expression patterns demonstrated a significant difference between KIT pattern 1 and KIT pattern 3, KIT pattern 3 showed a higher mean of eosinophil count. There was no significant correlation between eosinophil count and KIT patterns (p = 0.2648). However, a positive correlation was observed between the KIT patterns and Patnaik and Kiupel grades (p = 0.0006 and p = 0.0267, respectively). There was no significant correlation between eosinophil count, IL-5, or VEGFr. Further studies should determine whether eosinophil counts are an independent predictor of clinical outcome or simply correlated with already known predictors.

ABSTRACT The aim of this study was to identify differences in morphogenesis, structure, and forage accumulation rate of Urochloa brizantha cv. MG13 Braúna, from Urochloa cv. Cayana and Urochloa cv. Convert 330 (sabiá grass) during the deferment period. The experimental design was completely randomized, with four replications in experimental plots of 12.25m2. The evaluations took place for two years, 2021 and 2022. The deferment period was 90 days. Phyllochron (PHY) and leaf senescence rate (LSR) were lower at the beginning of deferred, contrary to leaf elongation rate (LER) and population density tillers (PDT). Stem growth rate (SGR) was higher in 2021 and at the beginning of deferment. Leaf growth rate (LGR) and total growth rate (TGR) were higher at the beginning of deferment. The braúna grass presented higher PDT. The SGR and the TGR of cayana grass are superior to those of braúna grass. The braúna grass produces a canopy consisting of lighter and denser byts, compared to other weeds. In Uberlândia, MG, braúna grass with an initial height of 30cm produces less stem, while cayana grass produces more forage during deferral.

Published: November 2023

ABSTRACT Spinal nerve root tumors are a group of neoplasms with a low incidence in the canine population. Clinical and paraclinical examinations can be difficult because the symptoms are non-specific, with a chronic and progressive course. The aim of the study was to describe the diagnostic and treatment protocol in three geriatric patients with spinal nerve root tumors. Paraclinical examinations were routine blood tests and imaging investigations: radiography, ultrasonography, and computed tomography of the spinal segment of interest. Magnetic resonance imaging and surgery were declined in all three cases, the owners opting for drug management or euthanasia.

ABSTRACT The objective of this study was to evaluate changes in the biochemical parameters of feedlot lambs fed with high concentrations of crude glycerin (GC). Forty crossbred lambs (Dorper × Santa Inês), non-castrated, weighing 21.7±2.7kg and 90 days old, were randomly assigned to four treatments (0, 10, 20, and 30% GC in the diet). To evaluate the biochemical parameters, blood samples (pre-prandial and 4 h after morning feeding) were collected on the first day and the day before slaughter, in each treatment. The high-density lipoprotein was linearly decreased (P<0.0001) when GC concentrations were increased in the diet. Alkaline phosphatase was quadratically affected by treatments (P=0.05), with greater values observed in blood from animals fed intermediate concentrations of CG, and gamma-glutamyl transferase was linearly increased (P=0.008). The blood urea was quadratically affected by treatments with lower values observed in blood from animals fed intermediate concentrations of CG. In conclusion, the replacement of up to 30% (based on dry matter) of corn grain by crude glycerin, in diets for feedlot finishing lambs, does not compromise the health status of these animals.

ABSTRACT Objective To assess the consumer food environment and its associations with socioeconomic factors in a midsize Brazilian city. Methods An ecological study that assessed the consumer food environment through audits in a stratified and proportional sample of food stores. The ESAO-S and the ESAO-R instruments were used. Access to healthy food was assessed using the Healthy Food Store Index and the Healthy Meal Restaurant Index. Socioeconomic and demographic characteristics and the Health Vulnerability Index were obtained from the 2010 Demographic Census. Statistical analyses were performed using the IBM®SPSSNo-Break®No-Break software. Result A total of 280 food stores were assessed. Only 47.1% of food stores for home consumption had fruits, vegetables, or legumes. High availability of ultra-processed food was identified, such as sugar-sweetened beverages (85.0%) and chocolate sandwich cookies (77.8%). The prices of some unprocessed foods and the availability of snacks were different according to socioeconomic characteristics. In food stores for immediate consumption, low availability of healthy options was identified, and, in most of them, natural juices had higher prices than sugar-sweetened beverages (87.1%). The mean Healthy Food Store Index score was 5.1 (SD=3.6), and the Healthy Meal Restaurant Index was 2.4 (SD=1.2). Conclusion These findings allow us to expand the knowledge about the consumer food environment, helping to implement public policies related to food supply.

Authors: Ergün Sibel , Bozdemir Büşra
Published: November 2023

ABSTRACT Objective This study aimed to determine the effects of the attitudes of mothers as health care professionals and their sociodemographic characteristics on their children’s eating habits. Methods The data of this descriptive and cross-sectional study were collected between January and March 2022, using a web-based survey of 386 mothers. Results The mean age of the mothers was 32.88±4.96 years, and the mean age of the children was 38.78±18.24 months. Regarding educational status, 62.7% of the mothers were university graduates, while 54.4% were nurses. A significant and positive correlation was found between the sub-dimensions of the Mother’s Attitudes towards the Feeding Process Scale and the Behavioral Pediatric Feeding Assessment scale (p=0.000). According to the multiple regression analysis, the main determinant of the picky eaters sub-dimension of the Behavioral Pediatric Feeding Assessment scale was the mother’s occupation (β=0.28; 95% Cl: 3.07, 6.50), the main determinant of the toddler refusal-general sub-dimension was negative affect during the meal (β=0.38; 95% Cl: 0.19, 0.32), the main determinant of the older children refusal - general sub-dimension was negative affect during the meal (β=0.30; 95% Cl: 0.16, 0.33), and the main determinant of the toddler refusal – textured foods sub-dimension was forced feeding (β=0.48; 95% Cl: 0.41, 0.63). Conclusion The study found that problems related to mothers’ attitudes toward the nutrition process were moderate and that these problems were mainly caused by mothers’ attitudes toward inadequate/unbalanced nutrition. It was also found that the children had moderate problematic eating behavior and eating habits.

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.
Profissionalização política: testando um índice multidimensional para o caso dos deputados federais brasileiros
Authors: Gabriel Gabryela
Published: November 2023

RESUMO Introdução: Na literatura de Ciência Política não há um critério bem estabelecido para se medir o grau de profissionalização dos políticos. Este artigo revisa um índice proposto para avaliar a profissionalização dos membros do Parlamento do Reino Unido adaptando-o ao caso dos deputados federais brasileiros eleitos em 2014. Materiais e métodos: O índice original de profissionalização é composto por quatro dimensões: 1) grau de comprometimento com a carreira; 2) tipo de background profissional antes de ingressar na atividade parlamentar; 3) idade de entrada no Legislativo (uma proxy para experiência de vida); e 4) ambição política. Após a aplicação do índice aos parlamentares brasileiros que serviram na 55ª legislatura, foram feitos testes de comparação de médias para verificar se os legisladores com status político alto possuíam um grau de profissionalização maior do que os demais. Foi utilizado para separar o grupo de status alto a classificação do Departamento Intersindical de Assessoria Parlamentar (DIAP) que anualmente publica a lista dos 100 Cabeças do Congresso Nacional. Resultados: Há uma diferença estatisticamente significativa a favor dos deputados de maior destaque. Os parlamentares premiados pelo DIAP são mais profissionais do que os não premiados em três das quatro dimensões analisadas (comprometimento com a carreira, experiência de vida e ambição política). Discussão: Com as devidas adaptações, o índice de profissionalização mostrou-se consistente e capaz de capturar a distância entre os parlamentares premiados e não premiados pelo DIAP. O uso de um modelo multidimensional é fundamental, pois, mais do que definir quem é ou não político profissional, ele permite medir o quão profissional um determinado político é.

Resumo Objetivos: investigar a violência digital no namoro entre adolescentes. Métodos: pesquisa qualitativa, utilizando o método da Inserção Ecológica, realizada numa Organização não Governamental, com amostra final de oito adolescentes dos gêneros masculino e feminino (16 e 19 anos). Os dados foram analisados segundo a técnica de Análise de Conteúdo, com triangulação de instrumentos e técnica: questionário biosociodemográfico; diário de campo; entrevista individual semiestruturada; questionário “Conhecendo as Relações de Namoro”. Resultados: a violência digital foi frequente e naturalizada no namoro; apesar da violência mútua, a bidirecionalidade na violência no namoro não significou simetria de gênero; a pandemia esteve ligada ao aumento diário do uso da Internet via celular, mas não potencializou a violência no namoro. A impulsividade marcou as tentativas de resolução de conflitos no namoro, associada não só à adolescência, mas também à crescente digitalização e aceleração das relações no âmbito da nossa sociedade. Os adolescentes foram vítimas diretas e/ou indiretas de violência nos principais microssistemas de desenvolvimento (familiar, escolar e bairro), expostos simultaneamente a diferentes tipos de violência, desde a infância. Conclusões: o microssistema digital pode ser visto como mais um contexto de perpetração e vitimização de violência. Recomenda-se que ações preventivas considerem as várias expressões da violência (física, psicológica, sexual e digital) e seus desdobramentos à saúde física e mental.

Abstract Objectives: to analyze the trend of morbidity and mortality indicators due to acute diarrheal diseases in children under five years old in Piauí. Methods: ecological study with data from the Information Technology Department at the Public Health System. The indicators of hospitalization rate and coefficient of mortality from the disease between 2000 and 2019 were calculated. A descriptive analysis of the indicators was carried out in the studied period and by the macro-regions in the State. For trend analysis, the simple linear regression model with log-transformation was used. Trends were classified as increasing, decreasing and stable, with a significance level of 5%. Results: the average on hospitalization rate was higher in the semi-arid macro-region (36.6/1000 children under five years old) and lower in Teresina (14.9/1000 children under five years old). The mean mortality coefficients were higher in the coastal macro-region (0.98/1000 live births) and lower in Teresina (0.47/1000 live births). The indicators showed a downward trend in all analyzed locations (p<0.05). A turning point was noted from 2009, with a significant reduction in hospitalization rates in the savanna and semi-arid macro-regions. Conclusion: indicators of morbidity and mortality due to acute diarrheal diseases in children under five years old showed a downward trend in Piauí between 2000 and 2019, with differences in trends between the evaluated macro-regions.

ABSTRACT In the context of a forest restoration program in a mining area in the eastern Brazilian Amazon, the objective of this study was to identify the species of trees of abiu-seringarana (Ecclinusa sp.) in forest remnants adjacent to the mine. As the identification of Ecclinusa based on external morphology alone is difficult, it was corroborated by molecular analysis. Leaf samples of three trees were compared with Ecclinusa in the Embrapa herbarium collection. DNA was extracted with a CTAB modified protocol for sequencing with ITS markers. Both the morphological identification and the alignment of the obtained sequences with material in GenBank indicated that the individuals belong to Ecclinusa guianensis, which is confirmed as the species occurring in the mining area.

Authors: FERNANDES André S. , ALMEIDA Maria L.S. , BOLDRINI Rafael
Published: November 2023

ABSTRACT Xenelmis is one of the 51 Neotropical genera of the aquatic beetle family Elmidae and is currently represented by 15 species distributed throughout the Neotropics. This genus of tiny beetles is especially well represented in South America, where all but one species can be found, and Brazil has the greatest richness, with ten species recorded so far. Here we describe and illustrate Xenelmis tuchaua sp. nov., a new Elmidae species with remarkable sexual dimorphism and unique diagnostic characteristics. The new species was found in an Amazonian stream located in Mount Roraima National Park, Roraima state, Brazil. We provide an updated species list for Xenelmis with comments on the occurrence of sexual dimorphism in the genus.

ABSTRACT A captive female of jaguar (Panthera onca), 12 years old, presenting an 8-day history of anorexia and lethargy, died in its enclosure in Manaus (Amazonas, Brazil). The necropsy revealed an abdominal multinodular ventral plaque into the mammary region. Additionally, in several locations of the subcutaneous tissue, there were multiple metastatic nodules of firm texture. Metastases were also observed in the lymph nodes, heart and lungs. The immunohistochemistry results revealed the cytoplasmic staining for cytokeratin on neoplastic cells, mild staining (+) for E-cadherin, moderate staining (++) for estrogen and progesterone receptors, and about 50 to 70% of staining for Ki-67. The neoplastic cells were negative for vimentin staining. Therefore, the histopathological examination led to a diagnosis of metastatic anaplastic mammary carcinoma, which is an unusual condition in wild felines.

ABSTRACT We present novelties on the occurrence of species belonging to the tribes Marcetieae, Melastomateae and Pyxidantheae (Melastomataceae) derived from revision of herbarium material and recent collections in the Brazilian Amazon. We report the rediscovery of the type species of Comolia, known only from the original material, the first records of Appendicularia, Dicrananthera and Blakea in the states of Pará, Roraima and Rondônia, respectively, and the first record of Pterogastra in Brazil. We provide maps with the updated geographical distribution for each species based on the revision of herbarium collections available in online databases followed by manual data cleaning. Geographic location coordinates were obtained after reviewing the identities and locality information of all herbarium specimens. Most distribution records result from recent botanical expeditions within protected areas in the Brazilian Amazon. The first records of Pterogastra in Brazil expand the diversity of Melastomataceae in Brazilian flora to 59 genera. These novelties reinforce the importance of botanical expeditions throughout the Brazilian Amazon to cover the extensive spatial gaps in taxonomic knowledge in the region which should be prioritized as the focus of botanical fieldwork.
