Resumo Objetivos: analisar a dinâmica espaço-temporal da prevalência de anomalias congênitas em municípios de Mato Grosso (MT), Centro-Oeste brasileiro, no período de 2008 a 2019. Métodos: estudo ecológico de casos residentes em MT, no período de 2008 a 2019. Utilizou-se a Variação Percentual Anual (VPA) dos coeficientes na análise de tendência, por meio de regressão de Prais-Winsten e identificação de clusters de alto risco. Resultados: a taxa de malformação congênita no estado foi de 6,52 por 1.000 nascidos vivos, apresentando tendência estacionária (VPA= -1,02; IC95%= -2,93-0,93). A maioria das anomalias congênitas apresentou tendência estacionária, exceto do aparelho cardiovascular (VPA=13,58; IC95%= 3,60-24,52). Neonatos com ≤7 pontos do índice de Apgar no primeiro e no quinto minutos de vida, apresentaram tendência crescente (VPA=2,30; IC95%= 0,05-4,60 e VPA=4,15; IC95%= 1,52-6,65, respectivamente). A distribuição espacial teve caráter heterogêneo com as maiores taxas médias de casos entre as macrorregiões de saúde Oeste, Centro-Norte e Sul, e a varredura espaço-temporal identificou três clusters de alto risco entre 2015 e 2019, com RR de até cinco vezes maior para anomalias. Conclusão: as anomalias congênitas em MT apresentaram uma dinâmica heterogênea com áreas de alto risco específicas. A tendência crescente entre fatores maternos e neonatais destaca a necessidade de estratégias regionais de prevenção e controle.

Abstract Objectives: to analyze the spatiotemporal dynamics of the prevalence of congenital anomalies in in cities of Mato Grosso (MT), in the Mid-West of Brazil, from 2008 to 2019. Methods: an ecological study of cases in MT during the period from 2008 to 2019. The Annual Percent Change (APC) of the coefficients was used in the tendency analysis, through Prais-Winsten regression and the identification of high risk clusters. Results: the congenital malformation rate in the State was 6.52 per 1,000 live births, demonstrating a stationary tendency (APC-1.02; 95%CI= -2.93-0.93). Most congenital anomalies showed a stationary tendency, except for those of the cardiovascular system (APC=13.58; 95%CI= 3.60-24.52). Newborns with an Apgar score of ≤ 7 at the first and fifth minutes of life showed an increased tendency (APC=2.30; 95%CI=0.05-4.60 and APC=4.15; 95%CI= 1.52-6.65, respectively). The spatial distribution was heterogeneous, with the highest average rates of cases in the West, Central North, and South health macro-regions. The spatiotemporal scan identified three high risk clusters between 2015 and 2019, with a relative risk (RR) up to five times higher for anomalies. Conclusion: congenital anomalies in MT exhibited a heterogeneous dynamic with specific high risk areas, and their increasing tendency among maternal and neonatal factors highlights the need for regional prevention and control strategies.

Destaca-se a importância da TRS na análise das opressões de gênero, raça e território, articuladas à exploração do trabalho, assim como para a compreensão da profissão inserida na relação necessária-porém-contraditória entre trabalho reprodutivo e produção de valor.

Abstract: The editorial discusses Social Reproduction Theory (SRT) and its contributions to Social Work, emphasizing the relationship between production and social reproduction in capitalism, based on the proposition of five key points. It highlights the importance of SRT in analyzing oppressions related to gender, race, and territory, which are intertwined with labor exploitation, as well as for understanding the profession embedded in the necessary-yet-contradictory relationship between reproductive work and value production.

Abstract Objective: To analyze the morbidity trend and space-time distribution clusters of confirmed COVID-19 cases in children and adolescents. Method: An ecological study of COVID-19 cases confirmed in the Information System from 2020 to 2022 in the age group from 0 to 19 years old, residents in Mato Grosso municipalities, Brazilian Midwest region. A trend analysis of the monthly morbidity rate of cases/100,000 inhabitants was used, following Prais-Winsten’s regression. A space-time distribution of the Bayesian incidence rate per 100,000 inhabitants was performed, in addition to a space-time scan to identify high-risk clusters. Results: Of all 79,592 COVID-19 cases studied, 51.6% were in females and 44.21% in people aged 15-19 years old. The mean monthly rate was 265.87 cases per 100,000 inhabitants, with a stationary trend in the period analyzed (Monthly Percentage Variation [MPV]) = 12.15; CI95%[MPV]: -0.73;26.70). The morbidity rate due to COVID-19 was higher in the female gender (283.14/ 100,000 inhabitants) and in the age group from 15 to 19 years old (485.90/100,000 inhabitants). An increasing trend was observed with a greater monthly time variation of 14.42% (CI95%[MPV]: 1.28;29.28)] among those aged from 10 to 14 years old. The primary cluster, which was also the one with the highest Relative Risk (RR = 5,16, p-value = 0.001), included 19 municipalities located in the North health macro-region. Conclusion: The findings indicated a monthly stationary trend in the study population, an increase in the age group from 10 to 14 years old, and areas at a higher risk for the disease in the North health macro-region of the state.

RESUMEN Los esquemas desadaptativos tempranos (EDT) son patrones disfuncionales de funcionamiento que se originan en las relaciones familiares formadas en la infancia/adolescencia. El soporte familiar se refiere a la calidad percibida de las relaciones intrafamiliares y al apoyo recibido. Por tanto, dependiendo de los esquemas activados, el soporte familiar puede percibirse como más o menos disfuncional. El entorno familiar y los EDT pueden afectar negativamente al bienestar. El objetivo de este artículo fue probar las relaciones entre los EDT, el soporte familiar percibido y el bienestar. Para ello se utilizó un cuestionario que contiene el Inventario de Percepción de Soporte Familiar (IPSF), el Cuestionario de Esquemas de Young (YSQ-S2) y el Escala PERMA-Profiler estudio está compuesto por una muestra de 171 participantes, con una edad media de 26,1 años y la mayoría mujeres (82,5%). Los EDT se correlacionan negativamente con el bienestar y el soporte familiar. El bienestar y el soporte familiar se asocian positivamente entre sí. El análisis de regresión mostró que el bienestar puede explicarse en función de los otros constructos. Los resultados obtenidos están en línea con la literatura, lo que sugiere la importancia de las relaciones entre todos los constructos estudiados. Sin embargo, es necesario replicar el estudio en una muestra más grande para poder obtener resultados significativos.

RESUMO Os esquemas iniciais desadaptativos (EIDs) são padrões disfuncionais de funcionamento que se originam nas relações familiares constituídas na infância e na adolescência. O suporte familiar refere-se à qualidade percebida das relações intrafamiliares e ao apoio recebido. Logo, dependendo dos esquemas ativados, o suporte familiar pode ser percebido como mais ou menos disfuncional. O ambiente familiar e os EIDs podem impactar negativamente o bem-estar. O objetivo deste artigo foi testar as relações entre os EIDs, a percepção do suporte familiar e o bem-estar. Para tanto, utilizou-se um questionário contendo o Inventário de Percepção do Suporte Familiar (IPSF), o Questionário de Esquemas de Young (YSQ-S2) e a Escala de Florescimento PERMA-Profiler. O estudo contou com uma amostra de 171 participantes, com média de idade de 26,1 anos e maioria mulheres (82,5%). Os EIDs apresentaram correlação negativa com o bem-estar e com o suporte familiar. Bem-estar e suporte familiar estavam positivamente associados entre si. A análise de regressão mostrou que o bem-estar pode ser explicado a partir dos demais construtos. Os resultados obtidos vão de acordo com a literatura, que sugere a importância das relações entre todos os construtos estudados. Porém, torna-se necessária a replicação do estudo em uma amostra maior, a fim de obter resultados significativos.

ABSTRACT Early maladaptive schemas (EMS) are dysfunctional patterns of functioning that originate in family relationships formed in childhood/adolescence. Family support refers to the perceived quality of intra-family relationships and the support received. Therefore, depending on the schemas activated, family support can be perceived as more or less dysfunctional. Family environment and EIDs can negatively impact well-being. This article aimed to test relationships between EMS, perceived family support and well-being. To this end, a questionnaire containing the Perceived Family Support Inventory (IPSF), the Young Schema Questionnaire (YSQ-S2) and the PERMA-Profiler Scale was used. The study consists of a sample of 171 participants, with an average age of 26.1 years and the majority of them being women (82.5%). EMS are negatively correlated with well-being and family support. Well-being and family support are positively associated with each other. The regression analysis showed that well-being can be explained based on the other constructs. The results obtained are in line with the literature, which suggests the importance of the relationships between all the constructs studied. However, it is necessary to replicate the study in a larger sample in order to obtain significant results.

ABSTRACT Increasing soybean yield in the MATOPIBA region can be attributed to fertility management, which is crucial to achieving maximum agronomic efficiency. Therefore, the proper management begins with the assessment of plant nutrition. This study aimed to evaluate soybean nutritional status in western Bahia using the Diagnosis and Recommendation Integrated System (DRIS). Database comprised 153 samples from commercial fields located in the research area. To carry out the evaluation using the DRIS method, the database contained information on nutritional levels and leaf productivity of the sampled areas. Database was divided into high-productivity populations (reference population) and low-productivity populations, based on the inflection point value of the cumulative cubic function of yield. The DRIS method allowed for evaluating the potential response to fertilization; however, this method was inefficient in recommending fertilizer doses in both subpopulations. For the sufficiency levels proposed by DRIS, the nutrients N, K, Ca, Mg and S had their maximum and minimum limits reduced, while Cu, Fe and Zn had their ranges of sufficiency expanded, when compared with ranges proposed by other authors. In addition, Zn and Mn were more limiting due to lack for the high-yield subpopulation, and P and Mn for the low-yield subpopulation. The most limiting nutrients due to excess were P and Zn for the high-yield, while K and S were limiting for the low yield subpopulation.

■ RESUMO Introdução: O nervo massetérico é utilizado como transferência nervosa na cirurgia de reanimação facial. Por conseguinte, foi realizado um estudo anatomotopográfico da abordagem deste nervo aplicado à cirurgia de reinervação facial. O objetivo foi descrever a anatomia do nervo massetérico como referência durante a cirurgia de reanimação facial. Método: Os dados foram analisados em 15 regiões massetéricas pertencentes a cadáveres adultos fixados em formaldeído. Resultados: Em 12 casos o nervo posicionava-se em relação ao terço posterior do arco zigomático. Emergiu da incisura mandibular a uma distância média de 14,7mm prévio ao processo condilar, e 8,8mm da borda inferior da arcada zigomática. As relações com os vasos massetéricos foram variáveis. Conclusão: O conhecimento anatômico do nervo é indispensável para a sua abordagem.

■ ABSTRACT Introduction: The masseteric nerve is used as a nerve transfer in facial reanimation surgery. Therefore, an anatomotopographic study of the approach of this nerve applied to facial reinnervation surgery was performed. The objective was to describe the anatomy of the masseteric nerve as a reference during facial reanimation surgery. Method: Data were analyzed in 15 masseteric regions belonging to adult cadavers fixed in formaldehyde. Results: In 12 cases, the nerve was positioned in relation to the posterior third of the zygomatic arch. It emerged from the mandibular notch at an average distance of 14.7 mm anterior to the condylar process and 8.8 mm from the lower border of the zygomatic arch. The relationships with the masseteric vessels were variable. Conclusion: Anatomical knowledge of the nerve is essential for its approach.

ABSTRACT The use of natural lignocellulosic fiber (NLF) biocomposites for the construction industry has been growing over the years, due to technical and environmental advantages. However, fiber-matrix incompatibility remains a major challenge. Various surface treatments have been investigated to improve fiber-matrix bonding, including sodium lignosulfonate (SLS), a potentially effective and environmentally friendly chemical. In this study, SLS treatment protocols were applied to piassava fibers to evaluate their influence on the fibers. Thermogravimetric Analysis (TG/DTG), X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM/EDS), Fourier-transform Infrared Spectroscopy (FTIR), moisture absorption measurements and tensile tests were performed to characterize the modifications. Results demonstrated, for the first time, the efficiency of SLS to remove extractives from the piassava surface. In general, partial degradation of the cellulosic structure was observed, noticeable by the slight drop in crystallinity index (from 42.80 to 39.82%), and an increase in the TG residual mass (from 21.35 to 31.90%), along with changes in DTG curves. However, a particular SLS treatment using ultrasonic bath was able to fully clean the surface preserving the cellulosic structure, and increasing the strength of fibers (from 386 ± 140 MPa to 524 ± 126 MPa).

Abstract Objective To define cut-off points for the values of the Maximum Handgrip Strength (MGS) test in long-lived elderly people. Method Cross-sectional study with a sample of long-lived elderly people, octogenarians and nonagenarians, healthy and functionally independent (robust group) and frail (fragile group). The MHS test was performed in triplicate, with the highest value obtained being considered. Sensitivity, specificity and cut-off values were calculated using the Receiver Operating Characteristic Curve (ROC). The Brazilian cut-off points and those of the European Consensus on Sarcopenia were used for the comparison study. Results 121 elderly people were evaluated, with a mean age of 84.5±5.3 years, 65 (53.7%) female, 46 (38%) from the frail group and 75 (62%) from the robust group. Cut-off points for MHS of 27 kgf for men and 19 kgf for women were found. Sensitivity and specificity values for men’s cutoffs were 94.44 and 65.79, respectively. For woman, they were 85.71 and 67.57. Based on these cutoff points, 23 (38.3%) individuals from the robust group were classified as having competitive strength, and therefore with probable sarcopenia, while according to the Brazilian and European cutoff points, the number is 35 (44.3%) and 14 (33.3%). Conclusion The study defined cut-off points for the oldest-old population and showed that the cut-off points defined so far for the Brazilian elderly population were not adequate for the oldest-old.

Resumo Objetivo Definir pontos de corte para os valores do teste de força máxima de preensão palmar (FMPP) em pessoas idosas longevas. Método Estudo transversal com amostra de pessoas idosas longevas, octogenárias e nonagenárias, saudáveis e independentes funcionais (grupo robusto) e frágeis (grupo frágil). O teste de FMPP foi realizado em triplicata, sendo considerado o maior valor obtido. Os valores de sensibilidade, especificidade e os pontos de corte foram calculados por meio da Curva Característica de Operação do Receptor (ROC). Foram utilizados os pontos de corte brasileiros e os do Consenso Europeu de Sarcopenia para estudo da comparação. Resultados Foram avaliadas 121 pessoas idosas, com idade média de 84,5±5,3 anos, 65 (53,7%) do sexo feminino, sendo 46 (38%) do grupo frágil e 75 (62%) do grupo robusto. Foram encontrados os pontos de corte para FMPP de 27 kgf para homens e 19 kgf para mulheres. Os valores de sensibilidade e especificidade para os pontos de corte masculinos foram 94,44 e 65,79, respectivamente. Para o sexo feminino foram de 85,71 e 67,57. A partir desses pontos de corte, 23 (38,3%) pessoas idosas do grupo robusto foram classificadas com força inadequada, e, portanto, com provável sarcopenia, ao passo que, de acordo com os pontos de corte brasileiros e europeus, o número é de 35 (44,3%) e 14 (33,3%), respectivamente. Conclusão O estudo definiu pontos de corte para a população longeva e mostrou que os pontos de corte definidos até o momento para a população idosa brasileira não se mostraram adequados para longevos.

The aim of this article is to analyze the notion of female empowerment considering contemporary literature to understand the actions of far-right women and their discourses towards ordinary women. Based on qualitative research conducted with Brazilian women who voted for Jair Bolsonaro, we hypothesize that the massification of a postfeminist culture throughout the 1990s and 2000s, as well as the emergence of neoliberal feminism and popular feminism (Banet Weiser; Gill; Rottenberg, 2020), provided new sensibilities that made possible a new type of far-right female discourses based on the valorization of traditional moral standards.

O objetivo deste artigo é analisar a noção de empoderamento feminino à luz da literatura contemporânea para compreender a atuação de mulheres de extrema-direita e sua interlocução com mulheres comuns. Com base em pesquisas qualitativas conduzidas com mulheres brasileiras que votaram em Jair Bolsonaro, aventamos a hipótese de que a massificação de uma cultura posfeminista ao longo das décadas de 1990 e 2000, bem como a emergência de fenômenos como o feminismo neoliberal e o feminismo popular (Banet Weiser; Gill; Rottenberg, 2020), propiciaram novas sensibilidades que tornaram possível um novo tipo de atuação feminina de extrema-direita baseada na valorização de padrões morais tradicionais.

L’objectif de cet article est d’analyser la notion d’autonomisation des femmes dans la littérature contemporaine afin de comprendre les actions des femmes d’extrême droite et leurs discours à l’égard des femmes ordinaires. Sur la base d’une recherche qualitative menée auprès de femmes brésiliennes ayant voté pour Jair Bolsonaro, nous émettons l’hypothèse que la massification d’une culture postféministe tout au long des années 1990 et 2000, ainsi que l’émergence du féminisme néolibéral et du féminisme populaire (Banet Weiser ; Gill ; Rottenberg, 2020), ont fourni de nouvelles sensibilités qui ont rendu possible un nouveau type de discours féminins d’extrême droite fondés sur la valorisation de normes morales traditionnelles.

RESUMO Neste artigo apontamos como a crise do pacto democrático de 1988 se originou a partir de novas dinâmicas fomentadas pela própria esfera pública pós-burguesa brasileira, a qual se desenvolveu em meio ao processo de redemocratização nacional. Na primeira seção apontamos de forma resumida como se deu a construção da esfera pública no Brasil desde 1822 até a redemocratização em 1988. Na segunda, apontamos como se deu a gênese e o desenvolvimento da esfera pública pós-burguesa no país, e, nas terceira e quarta seções, apontamos como sua crise se originou a partir de embates no âmbito do debate público que passavam ao largo da institucionalidade e mobilizavam a contrapublicidade: performances disruptivas e recebidas como indecorosas. Nesse sentido, argumentamos que o bolsonarismo, ao fomentar o que denominamos como contrapublicidade dominante, coloca a Nova República, novamente, sob a Espada de Dâmocles.

ABSTRACT In this article, we point out how the crisis of the 1988 democratic pact originated from the new dynamics fostered by the Brazilian post-bourgeois public sphere itself, which developed in the midst of the national redemocratization process. In the first section, we briefly indicate how the public sphere in Brazil was built from 1822 until redemocratization in 1988. In the second section, we show the genesis and development of Brazil’s post-bourgeois public sphere. And, in the third and fourth sections, we describe how its crisis originated from clashes in the public debate that bypassed the institutions and mobilized counterpublicity: disruptive performances perceived as indecorous. In this sense, we argue that Jair Bolsonaro and his supporters, by fostering what we call dominant counterpublicity, puts the New Republic, again, under the Sword of Damocles.

Resumen El arrepollamiento del banano ahogado acorta la distancia entre pecíolos de hojas alternas, lo que permite la salida de la parte distal de la inflorescencia; sin embargo, la parte basal se atasca en la garganta. Se evaluó el efecto del arrepollamiento en el crecimiento de Musa spp. cv Nanica (AAA) y la relación de las variaciones climáticas y el estado nutricional con este trastorno fisiológico fueron determinados. El experimento se llevó a cabo de septiembre 2018 a agosto 2019 en Registro, estado de São Paulo, Brasil. El diseño experimental fue completamente al azar con dos tratamientos y diez repeticiones, en parcelas subdivididas en el tiempo (meses). La evaluación consistió en determinar la intensidad del síntoma, número de hojas, altura de la planta, número de manos, longitud del tallo, síntomas de deficiencia nutricional y otras anomalías, contenido de nutrientes de las hojas. El crecimiento de las plantas no se vio afectado por el arrepollamiento, solo el número de manos en los meses de octubre 2018 y junio 2019 a agosto 2019 (p< 0.05). El arrepollamiento ocurrió durante todo el año, con predominio de síntomas severos de abril a junio debido a una reducción de la temperatura y radiación. Los frutos torcidos, unidos por fusión de partes florales y con diferentes tamaños ocurrieron, respectivamente, en 21.67, 60.83 y 17.52% de las plantas sintomáticas, asociados con la temperatura fresca durante la diferenciación de la fruta femenina. El arrepollamiento, así como anormalidades en el racimo y las frutas se relacionaron con deficiencia de Zn (p< 0.05). La deficiencia de Ca a bajas temperaturas, la menor disponibilidad de radiación y la alta humedad relativa también se asociaron con el arrepollamiento. El exceso de P en el suelo, así como las condiciones climáticas adversas contribuyeron a la limitación de estos nutrientes.

Abstract Choked banana presents closeness of petioles looks that allows the exit of the distal part of the inflorescence, but not the basal part is stuck up at the throat. The aim of this study was to avaluate the effect of choking on the growth of Musa spp. cv Nanica, as well as to investigate how the climatic variations and status nutritional of plants are associated whith this physiological disorder. The experiment was conducted in September/2018 in August/2019 in Registro, São Paulo state, Brazil. The experimental design adopted was completely randomized with two treatments and ten repetitions, in sub-divided plots over time (months). The evaluation consisted in determining the intensity of the symptom, number of leaves, plant height, hand number, stalk length, symptoms of nutritional deficiency and other abnormalities, leaf nutrient contents. Plant growth was not impacted by choking, only the hands number in the months of October/2018 and June/2019 to August/2019 (p< 0.05). Choking occurred throughout the year, with a predominance of severe symptoms of April in June due a redução da temperatura e radiation. The twisted fruits, united by fusion of floral parts and with different sizes occurred, respectively, in 21.67, 60.83 and 17.52% of the symptomatic plants, associated with the cool temperature during the differentiation of the female fruit. Choking and abnormalities in the bunch and fruits were associated with Zn deficiency (p< 0.05). The deficiency of Ca at low temperatures, the lower availability of radiation and the high relative humidity were also associated with the choking. The excess of P in the soil, as well, the adverse climatic conditions contributed to the limitation of these nutrients.

Resumen El objetivo es caracterizar a la división sexual/cis-hetero-binario-generificada del trabajo, la división racial del trabajo y la división territorial/internacional del trabajo como dimensiones indisociables de la división social del trabajo en el capitalismo. Metodológicamente asume al materialismo histórico-dialéctico y ubica en la racialización/etnización, en la cis-hetero-binário-generificación y en la dependencia, la raíz del racismo, la misoginia, la bi, lesbo, trans y homofobia y la xenofobia. Hace una revisión crítica de datos sobre la realidad de NuestrAmérica y trae el ejemplo de la unidad de luchas en el caso de las mujeres. Concluye sobre la imprescindibilidad de la lucha antirracista, antipatriarcal y anti-imperialista para la construcción del Trabajo Social crítico.

Abstract The objective of this research was to characterize the sexual/ist-hetero-binary-gendered division of labor, the racial division of labor and the international/territorial division of labor as inseparable dimensions of the social division of labor in capitalism. Methodologically the dialectical and historical materialism is assumed and situates the root of racism, misogyny, bi, lesbo, trans, and homophobia and xenophobia in the racialization/etnization, in the cis-hetero-binary-genderization and in the dependency. A critical review of data of NuestrAmérica (Caribbean and Latin American) reality and the example of the unit of struggles in the case of women is presented. The research concludes on the indispensability of antiracist, anti-patriarchal and anti-imperialist struggles to the construction of the Social Work Critical.

OBJECTIVES: To investigate whether quantitative textural features, extracted from pretreatment MRI, can predict sustained complete response to radiofrequency ablation (RFA) in patients with hepatocellular carcinoma (HCC). METHODS: In this IRB-approved study, patients were selected from a maintained six-year database of consecutive patients who underwent both pretreatment MRI imaging with a probable or definitive imaging diagnosis of HCC (LI-RADS 4 or 5) and loco-regional treatment with RFA. An experienced radiologist manually segmented the hepatic nodules in MRI arterial and equilibrium phases to obtain the volume of interest (VOI) for extraction of 107 quantitative textural features, including shape and first- and second-order features. Statistical analysis was performed to evaluate associations between textural features and complete response. RESULTS: The study consisted of 34 patients with 51 treated hepatic nodules. Sustained complete response was achieved by 6 patients (4 with single nodule and 2 with multiple nodules). Of the 107 features from the arterial and equilibrium phases, 20 (18%) and 25 (23%) achieved AUC >0.7, respectively. The three best performing features were found in the equilibrium phase: Dependence Non-Uniformity Normalized and Dependence Variance (both GLDM class, with AUC of 0.78 and 0.76, respectively) and Maximum Probability (GLCM class, AUC of 0.76). CONCLUSIONS: This pilot study demonstrates that a radiomic analysis of pre-treatment MRI might be useful in identifying patients with HCC who are most likely to have a sustained complete response to RFA. Second-order features (GLDM and GLCM) extracted from equilibrium phase obtained highest discriminatory performance.
