DINÂMICAS DE EXCLUSÃO: NACIONALISMO E A CRISE MIGRATÓRIA NO HORIZONTE DA DEGENERAÇÃO DEMOCRÁTICA
Authors: Ventura Raissa Wihby , Moraes Guilherme Cardoso de
Published: January 2025

Resumo Este artigo aborda as complexidades da crise da democracia contemporânea com base em uma perspectiva analítica e normativa orientada pela escuta. Nosso objetivo não é discutir a existência de uma crise democrática, nem definir ou debater conceitos como populismo de direita e novas direitas. Em vez disso, contestamos, inicialmente, os diagnósticos que desconsideram o papel do nacionalismo e sua relação com as migrações denominadas indesejadas como fatores relevantes para a compreensão da crise democrática. Na sequência, apresentamos os limites normativos dessas abordagens, mais especificamente no que se refere à relação entre democracia e nacionalismo, que, argumentamos, deveria ser problematizada em vez de ser assumida e justificada nas análises sobre as dinâmicas de exclusão associadas à degeneração democrática.
O CORPO COMO DISCURSO ENTRE A CAPOEIRA E A EDUCAÇÃO EM CIÊNCIAS: GINGAS INTERCULTURAIS POSSÍVEIS
Authors: SANTOS TARYN SOFIA ABREU DOS , KATO DANILO SEITHI
Published: January 2025

RESUMO: O presente artigo teve como objetivo, ao considerar os processos educativos que se expressam a partir do corpo, construir gingas interculturais entre o saber tradicional de matriz afro-brasileira e a Educação em Ciências. A ginga é uma representação corpórea que expressa negociação na capoeira. Desse modo, as gingas interculturais constituem-se em diálogos assentados nos marcos teóricos da interculturalidade crítica. Os resultados apresentados compõem uma dissertação de mestrado realizada em uma comunidade remanescente de ancestralidade africana. O objeto da análise foi o acompanhamento de uma intervenção do projeto extensonista Sala Verde, uma ação da Universidade Federal da Bahia no âmbito da Educação em Ciência. O território que vive o processo de certificação quilombola é São Francisco do Paraguaçu, Bahia, desde 2014 afetado por tal proposta ancorada nos pressupostos Ciência, Tecnologia e Sociedade. Os dados empíricos foram construídos mediante entrevistas semiestruturadas com mestres de capoeira da região, a partir de suas marcas discursivas remetentes aos saberes tradicionais afro-brasileiros; e literatura científica - lentes que possibilitaram o acompanhamento das mediações pedagógicas realizadas pelo Sala Verde com os moradores locais, no decurso de uma imersão etnográfica amparada em Restrepo. A interface dessa relação foi concebida sob o viés do corpo como discurso sócio-histórico nas concepções de Bakhtin, o que resultou nas gingas interculturais de dissenso que negam a diferença étnico-racial e a marcam em uma base de hierarquização inferior e gingas de consenso que tratam a diferença cultural com reciprocidade.

Published: January 2025

ABSTRACT: This article aims to present the perceptions of teachers belonging to the Santa Catarina state education network about democratic school management. It corresponds to an excerpt from a research project, the problem surrounding the perceptions of basic education teachers from this network about democratic management in the day-to-day running of their schools. The research is characterized as qualitative and quantitative, with the analysis of data obtained from applying an online questionnaire to teachers in the state education network. It also includes a discussion of the government policies that regulate school management in the state network, Decree No. 1,794/2013 (Santa Catarina, 2013) and Decree No. 194/2019 (Santa Catarina, 2019a). Among the theoretical references that underpin the analysis, we highlight Cury (2007), Vieira (2007), Souza (2009; 2012), Lima (2013), who discuss the concepts related to democratic management; Alves (2019), Palú and Petry (2020), problematize liberal democracy, which delimits democratic management in schools; and consequently, compromises the recognition and participatory parity (Fraser, 2002; 2006; 2007) of teachers. Although the results indicate that democratic management is materializing in state schools, some teachers do not recognize it, which may be associated with successive government policies that limit participation and delay the implementation of democratic school management.

Published: January 2025

RESUMO: As propostas contemporâneas de políticas educacionais inclusivas e sustentáveis, como a da Educação Especial na Perspectiva da Educação Inclusiva e da Educação Integral em Tempo Integral, são fundamentais para a superação de desigualdades. Aos estudantes do público da Educação Especial, as políticas educacionais brasileiras recomendam a oferta de Atendimento Educacional Especializado (AEE) no contraturno escolar, assim como preveem o aumento da oferta de Educação em Tempo Integral. O presente estudo visou analisar como o AEE funciona em escolas de tempo integral, dado que o estudante deve permanecer por sete horas-relógio, em média, na unidade educacional, e consequentemente com perdas de direitos, ou ao AEE ou à participação plena nas atividades da turma. A coleta de dados envolveu documentos, questionários e observação sistemática e entrevistas com professores de três escolas de tempo integral com matrícula de estudantes do público da Educação Especial. Os resultados, delimitados às entrevistas com os professores do ensino comum e do AEE, sugerem que as políticas de Educação Integral e Educação Especial na perspectiva da educação inclusiva tem propósitos e finalidades congruentes, porém, na prática, há ainda conflitos entre as duas políticas, que demandam redefinição do AEE.

Published: January 2025

Abstract: Given the importance of political representation for Brazilian democracy, as well as the inseparable relationship between parliamentary action and policy making, this article presents the results of a study that evaluated the mandate of a Black Brazilian state representative. On the one hand, research in public administration tends to focus on the executive branch; studies about other powers are less common, especially regarding the legislative branch. On the other hand, there is a long history of studies in this area in political science, both in legislative studies and especially in studies on the political representation of women in parliaments. The mandate was evaluated for effectiveness, that is, its ability to materially represent the interests of women and the groups it intended to represent. Mobilizing literature on the relationship between descriptive, substantive, and symbolic representation exercised by women in political positions, we evaluated the mandate’s contribution to dimensions such as: democratic strengthening, political administration, and results of parliamentary action.
The confirmation hearings of appointees to the Brazilian Federal Court of Accounts post-1988: appointment power and horizontal accountability
Authors: Olivieri Cecília , Gonçalves David Guilherme Andriotto , Casaniga Guilherme Lissone
Published: January 2025

Abstract: The article analyzed the confirmation hearings of Court of Accounts (TCU) ministerial nominees between 1988 and 2023 to understand what they reveal about the appointment process and horizontal accountability. Using content analysis of Senate hearing transcripts the study reveals preferences and conflicts that are not apparent in the senators’ votes. Among these preferences is the minister profile valued by Senators (experienced politicians with “political sensitivity”). The research also identifies the topics that interest senators in the debate on horizontal accountability and reveal the conflicts between senators and TCU (regarding the autonomy and responsiveness of the TCU before Congress). In other words, the confirmation hearings for TCU ministers are a significant locus of power, comparable to those for positions at the Central Bank of Brazil and in foreign relations.

Resumo: O artigo analisou as sabatinas dos indicados a ministro do TCU entre 1988 e 2023 para entender o que elas revelam sobre o processo de nomeação e a accountability horizontal. O método é a análise de conteúdo, e o material utilizado foram as transcrições das sessões de arguição no Senado. A análise das sabatinas revela preferências e conflitos que a votação em plenário não permite acessar. Entre essas preferências está o perfil de ministro valorizado pelos Senadores (políticos experientes com “sensibilidade política”). Identificamos também os temas que interessam aos senadores no debate sobre a accountability horizontal e revelamos os conflitos entre senadores e TCU (a respeito da autonomia e responsividade do TCU perante o Congresso). Ou seja, as sabatinas dos ministros do TCU também são locus de poder relevante, como nos casos do Banco Central e das relações exteriores.

ABSTRACT Cut sunflower holds significant potential for the floriculture market in Brazil, with its development being strongly influenced by air temperature. This study aimed to determine the thermal sum required for the emergence of various phenological stages and to estimate the phyllochron of 12 newly cut sunflower genotypes in southwestern Mato Grosso, Brazil. The research was conducted in Cáceres, MT, where seedlings were planted in two beds, and ten central plants per genotype in each bed were marked to track reproductive stages, classified as R1, R4, and R5. Air temperature measurements were used to calculate the accumulated thermal sum for the stages emergence-R1, R1-R4, R4-R5, and emergence-R5. A linear regression analysis was performed to assess the relationship between the number of leaves accumulated on the stem and the accumulated thermal sum, enabling phyllochron estimation for each genotype. The accumulated thermal sum for emergence-R1 ranged from 445.29 ºC/day to 791.08 ºC/day, and for emergence-R5, it ranged from 806.51 ºC/day to 1139.10 ºC/day. The relationship between leaf number on the stem and accumulated thermal sum was linear, with a coefficient of determination between 0.98 and 0.99, and phyllochron values ranged from 20 to 26 °C day leaf−1. Thus, the sunflower genotypes assessed exhibited values consistent with standards observed in other genotypes and ornamental species on the market, indicating that they possess commercialization potential and that the region’s climate conditions are suitable for cultivation.

Cancer is the second leading cause of death worldwide. Cancer cachexia is a multifactorial catabolic syndrome responsible for almost one third of cancer-related deaths. Drug repurposing has been used in oncological research and drugs like clenbuterol and metformin seem to be reasonable candidates in the context of cancer cachexia, because the former is a β2-agonist that stimulates muscle gain and the latter has anti-inflammatory properties. The aim of this study was to assess the effects of a short-term treatment with metformin and clenbuterol, isolated or combined, on tumor growth and cancer cachexia parameters in Walker 256 tumor-bearing rats, a model of cancer cachexia. To this end, Wistar rats were separated into 8 groups and 4 of them were injected with Walker 256 tumor cells (W groups). Control (C) and W groups received the following treatments: metformin (M), clenbuterol (Cb), or metformin combined with clenbuterol (MCb). Body and tumor weight, metabolic parameters, and oxidative damage in the tumor were assessed. Compared to the C group, the W group showed body weight loss, hypoglycemia, hyperlactatemia, and hypertriacylglycerolemia. None of the treatments could reverse body weight loss, although they reversed the alterations of the assessed plasma metabolic parameters. Surprisingly, only clenbuterol alone reduced tumor weight. Hydrogen peroxide production and lipid peroxidation in tumor tissue was increased in this group. In conclusion, metformin and clenbuterol ameliorated metabolic cachexia parameters in Walker tumor-bearing rats, but only clenbuterol reduced the tumor weight, probably, through a lipid peroxidation-dependent cell death.

Published: January 2025

Osteosarcoma (OS) remains the most common bone tumor and the prognosis for many patients remains stagnant due to the unsatisfactory therapeutic effect of conventional treatment regimens. This research explored the effect and mechanism of a novel natural product, Eriocalyxin B (EB), in pathogenesis and immunotherapy in OS. Cell Count Kit 8 assay, colony formation assay, and wound healing assay were employed to detect the proliferative, colony-forming, and migratory abilities of human OS cells following EB treatment. Moreover, xenograft growth assay was performed to assess the effect of EB on OS in vivo. Subcutaneous OS models constructed in immunocompetent mice were employed to evaluate the effect of EB treatment in combination with immune checkpoint blockades (ICBs) PD1ab and CTLA4ab. Immunohistochemistry (IHC) staining was utilized to detect the level of CD8+ T cells infiltration and Ki67 expression. TARGET database, RNA interference technology, and qPCR assay were employed to explore the mechanism of EB on OS. EB inhibited the proliferative, colony-forming, and migratory abilities of the human OS cells MG63 and U2OS both in vitro and in vivo. TARGET data analysis demonstrated that up-regulation of TCEA3 was significantly negatively correlated with overall survival in OS patients. EB exerted anti-tumor activity via downregulation of TCEA3. EB, in conjunction with ICBs, synergistically optimized anti-tumorigenic activity against OS in immunocompetent mice. EB may promote infiltration of CD8+ T cells and down-regulate Ki67 expression. These results signaled that EB may have a role as a candidate therapeutic or preventive agent for the treatment of OS.

Necrotizing enterocolitis (NEC) is a severe intestinal disease of multifactorial origin that primarily affects premature infants. Approximately 27% of NEC babies develop short gut (SG) secondary to extensive intestinal resection, and 10% will have chronic dependence on total parenteral nutrition. We evaluated the Botox treatment in SG model rats. Twenty-day-old weanling male rats (weight range 38-70 g, n=72) were divided into four groups (n=18 each): 1) Control (fed a regular liquid diet); 2) Botox (Control submitted to laparotomy and intestinal injection of Botox®); 3) SG (short gut); and 4) SG and Botox (SG+Botox®). After seven post-operative days, samples were collected for biometrics [body weight (BW), intestine weight (IW) and IW/BW ratio (IBR), and intestine length (IL) and height (IH)], histometric analysis [villous height (VH), crypt depth (CD), muscular thickness (MT), and PCNA index)], and intestinal transit time (ITT). BW, IW, and IL decreased in SG (P<0.05). IH, VH, and PCNA index increased in Botox groups [Control = SG < Botox and SG+Botox (P<0.05)], CD increased in Botox, SG, and SG+Botox (P<0.005), and MT was higher in SG and SG+Botox. Botox groups had lower ITT (P<0.05). Botox provided dilatation and histological changes in SG. These findings suggested that Botox improved adaptation and might be applied in SG with promising results.

ABSTRACT Cementitious Green Hybrid Concrete (CGHC) is gaining recognition as a sustainable choice for low-volume roads, providing environmental benefits and improved mechanical strength over traditional concrete. CGHC reduces traditional cement demand, thus lowering carbon emissions, while its durability minimizes repair needs, extending structural lifespan and reducing resource consumption. This study employs Response Surface Methodology (RSM) with a Central Composite Design (CCD) to analyze the influence of varying proportions of cement, fine aggregate, and coarse aggregate on CGHC's compressive and flexural strengths. The investigation evaluates the impact of coconut shell (COS), lime powder (LP), and rice husk ash (RHA) as partial replacements—substituting COS for coarse aggregate, RHA for fine aggregate, and LP for cement across twenty M30 grade concrete mixes. Results show that RHA and LP replacements generally enhance strength, with RHA substitution at 20% for fine aggregate yielding optimal strength. In contrast, increased COS content reduces strength. This research demonstrates RSM's effectiveness in optimizing CGHC properties, underscoring its potential for eco-friendly road applications.
Analysis and evaluation of Cost of Quality (COQ) elements on total quality costs in construction projects: design of experiments
Authors: Palanisamy Indhiradevi , Palanichamy Saravanakumar
Published: January 2025

ABSTRACT The Cost of Quality (COQ) is widely recognized in manufacturing as a critical performance metric, yet its application in the construction industry remains less established due to fundamental differences in characteristics and environments. While integrating COQ into the planning and building phases of construction projects appears straightforward in theory, practical implementation proves challenging. This study investigates the impact of COQ elements on total quality costs, analyzing 16 building projects using factorial design techniques. Internal and external failure costs emerged as significant factors affecting overall quality, with variations in prevention, appraisal, and failure costs emphasizing the critical role of preventive measures in minimizing quality-related expenses. Statistical hypothesis testing confirmed the substantial influence of failure costs on total quality costs, with Yate’s algorithm and 24 factorial design experiments offering deeper insights into factor effects. The findings underscore the importance of strategic preventive actions, providing valuable implications for enhancing quality management practices, reducing failure costs, and improving overall project efficiency in the construction sector.

Published: January 2025

ABSTRACT Composite materials, renowned for their superior mechanical properties and lightweight characteristics, are widely used in high-precision industries such as aerospace, automotive, and chemical manufacturing. The production of composite components heavily relies on high-quality molds, where contaminants like mold release agents and resins accumulate over time, compromising the surface quality and durability of both the mold and the composite products. This study investigates laser cleaning as a non-contact, sustainable method to remove these contaminants while preserving material integrity. Surface characteristics were analyzed using scanning electron microscopy (SEM) and energy-dispersive spectroscopy (EDS). The optimal laser parameters—200 W power, 2500 mm/s scanning speed, 2000 kHz repetition rate, 40 ns pulse duration, and a 0.01 mm scanning interval—effectively removed contaminants and improved surface quality, reducing roughness from 1.840 μm to 0.474 μm. Additionally, mechanical properties were assessed using a micro hardness tester and a multi-function tribometer, showing a 13% increase in surface hardness and an 8% improvement in wear resistance, indicating enhanced surface tribological properties. These findings underscore the potential of laser cleaning to maintain composite mold quality, extend service life, and provide an efficient, environmentally friendly alternative to conventional methods.

Published: January 2025

Objetivo: analizar la autonomía reproductiva de las mujeres durante la pandemia de COVID-19, en función de factores sociodemográficos, clínicos y reproductivos. Método: estudio cuantitativo con diseño transversal, realizado con 314 mujeres de 18 a 49 años. La información se obtuvo mediante un cuestionario online que consta de datos sociodemográficos, clínicos y reproductivos y de la Escala de Autonomía Reproductiva. Para comparar variables se utilizaron las pruebas de Mann-Whitney y t de Student. Resultados: hubo una diferencia estadísticamente significativa entre los puntajes medios de “toma de decisiones” y estado civil (p = <0,001); y entre “ausencia de coerción” y “comunicación” y franja etaria (p = 0,03 y <0,001), residencia (p = <0,001 y <0,01), educación (p = 0,02 y 0,02), embarazo (p = <0,001 y 0,04) y anticoncepción (p = 0,02 y <0,001). Conclusión: no tener pareja sexual influyó positivamente en la autonomía en la toma de decisiones reproductivas durante la pandemia de COVID-19. Las mujeres de menor franja etaria, residentes en la capital, mayor nivel de escolaridad, que nunca habían estado embarazadas y que utilizaban anticonceptivos durante la pandemia mostraron mayor autonomía en ausencia de coerción y comunicación. Se identificaron grupos que requieren mayor atención e intervenciones que contribuyan a su salud sexual y elecciones reproductivas.

Objective: to evaluate the construct validity and reliability of the Brazilian version of the Instrument for the Evaluation of Advanced Practice Nurse Competencies in Primary Health Care. Method: methodological study carried out in 78 primary health care centers in the southeast of Brazil, with 215 nurses. Data was collected using three instruments: the sample characterization form, the Brazilian version of the Advanced Practice Nurse Competency Assessment Instrument and the Therapeutic Interventions category of the Nurse Competency Scale. Construct validity was verified using confirmatory factor analysis and Spearman’s correlation coefficient. Reliability was assessed using Cronbach’s alpha and composite reliability. Results: in the factor analysis, the model converged on a satisfactory result, with six items excluded, resulting in an instrument with 38 items distributed over eight dimensions. In convergent construct validity, positive, significant correlations were observed (p<0.0001) and ranged from weak to moderate in magnitude (r=0.2701 and r=0.397). Satisfactory evidence was found through the Composite Reliability analysis (0.78-0.89). Conclusion: the instrument showed evidence of construct validity and internal consistency. It could be used to help implement strategies for developing advanced practice in nursing.

Abstract We aim was to evaluate the chemical attributes of the soil under the effect of the incorporation of agronomic/lignocellulosic residues, in natura and spent/post-cultivation of mushrooms and the remineralizer from bentonite in Chromic Abruptic Acrisol, in the municipality of Areia, PB, Brazil. The research was carried out in a greenhouse and consisted of 13 treatments, resulting from a 3 × 2 × 2 + 1 factorial arrangement in CRD, with four replications. Data were evaluated for normality and homogeneity of variance using the of Shapiro-Wilk and Bartlett, and when significant then submitted to analysis of variance (ANOVA), Scott-Knott means test, and Dunnett at 5% significance. In addition, principal component analysis (PCA) and Pearson correlation were performed. The incorporation of agronomic wastes under in natura conditions and SMS with the remineralizer increased the fertility variables of the Chromic Abruptic Acrisol, with a significant increase in the levels of exchangeable bases, organic carbon, soil organic matter, cation exchange capacity, base saturation, and phosphorus available. The PCA showed that sugarcane bagasse and banana leaf treatments, both in the in natura condition and without incorporation of remineralizer, were the most correlated with the CEC, SB, and V% variables. Then, the application of lignocellulosic waste in the in natura and spent mushroom substrate (SMS) conditions without the use of a remineralizer increases total organic carbon and cation exchange capacity and phosphorus available.

Published: January 2025

Abstract The pirarucu (Arapaima gigas) is a native fish of the Amazonian basin. It plays an essential role in food security and the maintenance of biodiversity. In the 1970s, researchers designated the species as endangered due to the deleterious effects of overfishing. The advancement of fish farming projects for large-scale production and management in protected areas have been a significant driving force behind scientific research. This pioneering study analyzes the global literature, scientific articles via the Scopus platform, and national interest through research projects registered on the Lattes platform. The authors employ data collection and organization techniques, including network science and topic modeling analysis. Brazilian research is prominent, with scientists leading national projects and ranking among the most productive in Scopus. Additionally, Brazilian institutions fund the majority of research on Scopus. The main areas of study focused on understanding the biological and technological aspects, especially those related to reproduction. Domestic research circuits mainly refer to applied research. The findings presented here illustrate the significance of conducting research in peripheral countries to address national concerns. Despite limited awareness of these findings beyond the local context, they offer substantial insights for developing local strategies.

ABSTRACT Objective: to identify the prevalence of fatigue and the relationship between professional, health and quality of life variables of professionals working in emergency care services. Method: a cross-sectional study, with 108 healthcare professionals, carried out in midwest Brazil, in 2021, using the Chalder Fatigue Scale and the World Health Organization Quality of Life-brief. The data were analyzed through descriptive statistics, association and correlation. Results: most participants were female (63.0%), aged between 18 and 25 years (41.7%), nursing technicians (50.0%) who worked in an Emergency Care Unit (75.0%). The mean fatigue assessment score was 5.9, and 72.9% were classified as fatigued. The mean quality of life score was 64.8 (±11.4). Participants who practiced physical activity and maintained a good diet had lower fatigue scores and reported better quality of life. A significant and inversely proportional correlation was identified between fatigue and all domains of quality of life. Conclusion: this study showed a high prevalence of fatigue. Quality of life was considered low, especially in the physical domain. The greater the fatigue, the worse the overall quality of life and domains. It is reinforced the need for measures and interventions to minimize the impacts of fatigue and low quality of life of professionals working in direct patient care.

ABSTRACT Objective: To investigate the sociodemographic, maternal, and gestational factors associated with the dietary total antioxidant capacity in pregnant Brazilian women. Methods: A cross-sectional study with 2,232 pregnant women aged 18 years old or older, in the first, second, and third trimesters of pregnancy, from eleven cities in the five Brazilian regions. A semi-structured questionnaire was applied to assess socioeconomic, demographic, and health data, and a 24-hour dietary recall (R24h) was used to assess food consumption and analyze the dietary total antioxidant capacity (DTAC), estimated using the ferric reducing antioxidant power (FRAP) method. Results: The median of DTAC was 5.32 mmol/day. Aracaju, Sergipe (SE) had the highest median of DTAC (6.44 mmol/day) and Palmas, Tocantins (TO) had the lowest (4.71 mmol/day). Pregnant women aged 20 to 34 years (OR 1.86; 95%CI 1.26-2.76), 35 years old or older (OR 3.68; 95%CI 2.21-6.14) and who were in the second trimester of pregnancy (OR 1.50; 95%CI 1.11-2.01) were more likely to be above the median DTAC. While pregnant women with higher education had a 67% lower chance of being above the median DTAC (OR 0.67; 95%CI 0.48-0.92). Conclusion: The study demonstrated that there are differences in antioxidant consumption in different cities in Brazil and that associated factors such as age, education, and gestational trimester can impact the intake of foods rich in antioxidants. The profile found draws attention to the importance of an adequate diet rich in antioxidants during prenatal care.

ABSTRACT Objective: To analyze the prevalence of bullying practices and associated factors among Brazilian adolescents, according to the National Survey of School Health 2019. Methods: This is a cross-sectional study with cluster sampling. The outcome variable, bullying practice, was assessed by the question: "In the last 30 days, have you mocked, ridiculed, teased, intimidated, or bullied any of your schoolmates to the point that they felt hurt, upset, offended, or humiliated?" (yes/no). Associations with sociodemographic characteristics, family environment, mental health, and risk behaviors were analyzed using Poisson regression with robust variance. Results: 12.1% (95%CI 11.7-12.6) of adolescents reported bullying others. Positive associations were found among boys (PR 1.66; 95%CI 1.55-1.77); self-declared Black (PR 1.23; 95%CI 1.11-1.36) and brown (PR 1.1; 95%CI 1.02-1.18) adolescents; private school students (PR 1.29; 95%CI 1.21-1.37); those who felt lonely (PR 1.17; 95%CI 1.09-1.26); thought life was not worth living (PR 1.28; 95%CI 1.19-1.39); were physically assaulted by a family member (PR 1.67; 95%CI 1.55-1.79); skipped classes (PR 1.23; 95%CI 1.15-1.31); used tobacco (PR 1.34; 95%CI 1.22-1.47), alcohol (PR 1.38; 95%CI 1.28-1.50), and drugs (PR 1.17; 95%CI 1.04-1.31) regularly; and had sexual relations (PR 1.26; 95%CI 1.18-1.35). Ages 16 and 17 (PR 0.82; 95%CI 0.76-0.89) and family supervision were protective factors (PR 0.70; 95%CI 0.66-0.75). Conclusion: Bullying was more likely among boys, younger adolescents, those with family and mental health issues, and those engaged in risk behaviors. The importance of practices, such as family supervision in preventing bullying, is highlighted.

RESUMO Objetivo: Analisar a prevalência de prática de bullying e fatores associados entre adolescentes brasileiros, segundo a Pesquisa Nacional de Saúde do Escolar 2019. Métodos: Estudo transversal, com amostragem por conglomerados. A variável desfecho, prática de bullying, foi obtida pela pergunta "Nos últimos 30 dias, você esculachou, zombou, mangou, intimidou ou caçoou algum de seus colegas da escola tanto que ele ficou magoado, aborrecido, ofendido ou humilhado?" (sim/não). Foram analisadas associações com características sociodemográficas, familiares, saúde mental e comportamentos de risco, utilizando regressão de Poisson com variância robusta. Resultados: 12,1% (IC95% 11,7-12,6) dos adolescentes relataram praticar bullying. Houve associação positiva entre meninos (RP 1,66; IC95% 1,55-1,77); autodeclarados pretos (RP 1,23; IC95% 1,11-1,36) e pardos (RP 1,1; IC95% 1,02-1,18); de escola privada (RP 1,29; IC95% 1,21-1,37), que sentiam-se solitários (RP 1,17; IC95% 1,09-1,26), que a vida não vale a pena (RP 1,28; IC95% 1,19-1,39), apanharam de familiar (RP 1,67; IC95% 1,55-1,79), faltaram às aulas (RP 1,23; IC95% 1,15-1,31), usavam tabaco (RP 1,34; IC95% 1,22-1,47), álcool (RP 1,38; IC95% 1,28-1,50) e drogas regularmente (RP 1,17; IC95% 1,04-1,31) e tiveram relação sexual (RP 1,26; IC95% 1,18-1,35). A idade 16 e 17 anos (RP 0,82; IC95% 0,76-0,89) e supervisão familiar foram protetoras (RP 0,70; IC95% 0,66-0,75). Conclusão: Praticar bullying foi mais provável entre meninos, mais jovens, com problemas familiares e de saúde mental, e comportamentos de risco. Observa-se a importância de práticas como supervisão familiar contra o bullying.

ABSTRACT Objective: To analyze the retail food environment and identify the presence of food swamps around public and private higher education institutions (HEIs) in Belo Horizonte, Minas Gerais. Methods: This is an ecological study with the analysis unit being a 500-meter buffer network around 81 in-person HEI units. The density and proximity between the HEIs and food purchasing establishments for immediate consumption were assessed according to the administrative category and per capita income of the census tract, as well as the presence of food swamps. Results: In 98.76% of the buffers there was at least one establishment for immediate consumption. Snack bars, restaurants, and bars were the categories most available and closest to the HEIs. The density of establishments was higher around private HEIs and around HEIs located in higher income areas. It was found that 95.06% of HEIs were located in areas classified as food swamps. Conclusion: Thus, the HEIs evaluated were exposed to neighborhoods with an unhealthy food environment, which may predispose university students to food choices based on the consumption of ultra-processed foods and alcoholic beverages.

RESUMO Objetivo: Analisar o ambiente alimentar de varejo e identificar a presença de pântanos alimentares no entorno de instituições de ensino superior (IES) públicas e privadas de Belo Horizonte, Minas Gerais. Métodos: Trata-se de estudo ecológico, que teve como unidade de análise o buffer network de 500 metros, traçado no entorno de 81 unidades de IES com ensino presencial. Foram avaliadas a densidade e a proximidade entre as IES e estabelecimentos de aquisição de alimentos para consumo imediato, de acordo com a categoria administrativa e renda per capita do setor censitário, além da presença de pântanos alimentares. Resultados: Em 98,76% dos buffers existia pelo menos um estabelecimento para consumo imediato. Lanchonetes, restaurantes e bares foram as categorias mais disponíveis e mais próximas das IES. A densidade de estabelecimentos foi maior no entorno das IES privadas e no entorno das IES localizadas em áreas de maior renda. Verificou-se que 95,06% das IES estavam localizadas em áreas classificadas como pântanos alimentares. Conclusão: Dessa forma, as IES avaliadas encontravam-se expostas a vizinhanças com ambiente alimentar não saudável, que podem predispor o público universitário a escolhas alimentares baseadas no consumo de alimentos ultraprocessados e bebidas alcoólicas.

Published: January 2025

Abstract Pinus occidentalis and Pinus caribaea are important conifers in La Sierra, Dominican Republic, used to recover degraded ecosystems. A study on their wood density obtained from stem discs at three relative heights (RH) as a composite sample showed that wood density increased with age class for both species and decreased with RH in the stem. A mixed repeated measures analysis of variance, followed by a regression approach to the effects model, indicates a statistically significant interaction between species, age class (AC), RH, [ , P ≤0.000, partial =0.814]. Simple bidirectional interactions between factors and all simple main effects are statistically significant. Basic density (BD) increased with age class for both species and decreased with RH in the stem. Pinus occidentalis had a 14.6% higher average wood density and is endemic. Therefore, efforts must be made to provide better silvicultural practices so that its population continues to be a viable asset.

ABSTRACT Objective: To assess the clinical outcomes of regenerative endodontic procedures using autologous platelet concentrate. Both regeneration and apexification procedures were examined and compared with each other. Material and Methods: The PRISMA 2020 Checklist has been utilized to carry out the systematic review and meta-analysis for the present study. PubMed, Scopus, Web of Science, EBSCO, Embase, and ISI Web of Knowledge have been reviewed for systematic literature until May 2023. A fixed-effect model and a Mantel-Haenszel methodology have been used to measure the risk ratio’s 95% confidence interval. Then, Metaanalyses were carried out utilizing Stata/MP version 17. Results: Duplicate studies were eliminated from the first review, 849 studies’ abstracts were reviewed, two authors reviewed 103 papers’ full texts, and finally, 20 articles were selected. The survival rate in regenerative endodontic procedures between apexification and regenerative endodontic procedures was −0.01 (RR: −0.01, 95% CI: −0.05, 0.02; p=0.35). Conclusion: Throughout the present meta-analysis, regenerative endodontic therapy is an effective intervention with a high survival and success rate in managing immature necrotic permanent teeth.

ABSTRACT Objective: To analyze the impact of the COVID-19 pandemic on the interval between diagnosis and initiation of treatment for oral cavity and oropharyngeal cancer in Brazil. Material and Methods: A time series study was conducted using secondary data extracted from the DATASUS system. The three-year period from 2019 to 2021 was selected to represent the baseline, onset, and peak of reported COVID-19 cases. The dependent variable of the study was the delay in starting anticancer treatment (>60 days after histopathologic diagnosis). Time series were analyzed using joint-point regression and monthly percentage changes (MPC) were estimated. Results: For oral cavity cancer, there were two periods of decrease in the delay in treatment initiation, from January 2019 to June 2020 (MPC= −0.7S, 95% CI = −0.3 to −3.2, p=0.004) and from November 2020 to December 2021 (MPC= −1.41, 95% CI = −2.2 to −0.6, p=0.00l). For oropharyngeal cancer, there was an increase in the percentage of delays in treatment initiation from January 2019 to February 2020 (MPC= 0.86, 95% CI = 0.2 to 1.5, p=0.014) and from May 2020 to December 2020 (MPC= 3.66, 95% CI = 1.2 to 6.2, p=0.005), with a decrease from December 2020 to December 2021 (MPC= −1.40, 95% CI = −2.3 to −0.5, p=0.003). Conclusion: The COVID-19 pandemic in Brazil had a greater impact on treatment initiation delay for oropharyngeal cancer than for oral cavity cancer. However, the percentage of delay in treatment initiation for oropharyngeal cancer showed fluctuation, with an increase in the pre-pandemic period and a decrease after December 2020.
