Parathyroidectomy: still the best choice for the management of severe secondary hyperparathyroidism / Paratireoidectomia: ainda a melhor escolha para o tratamento do hiperparatireoidismo secundário grave

Abstract Introduction: Management of secondary hyperparathyroidism (SHPT) is a challenging endeavor with several factors contruibuting to treatment failure. Calcimimetic therapy has revolutionized the management of SHPT, leading to changes in indications and appropriate timing of parathyroidectomy (PTX) around the world. Methods: We compared response rates to clinical vs. surgical approaches to SHPT in patients on maintenance dialysis (CKD 5D) and in kidney transplant patients (Ktx). A retrospective analysis of the one-year follow-up findings was carried out. CKD 5D patients were divided into 3 groups according to treatment strategy: parathyroidectomy, clinical management without cinacalcet (named standard - STD) and with cinacalcet (STD + CIN). Ktx patients were divided into 3 groups: PTX, CIN (cinacalcet use), and observation (OBS). Results: In CKD 5D we found a significant parathormone (PTH) decrease in all groups. Despite all groups had a higher PTH at baseline, we identified a more pronounced reduction in the PTX group. Regarding severe SHPT, the difference among groups was evidently wider: 31%, 14% and 80% of STD, STD + CIN, and PTX groups reached adequate PTH levels, respectively (p<0.0001). Concerning the Ktx population, although the difference was not so impressive, a higher rate of success in the PTX group was also observed. Conclusion: PTX still seems to be the best treatment choice for SHPT, especially in patients with prolonged diseases in unresourceful scenarios.

Resumo Introdução: O manejo do hiperparat-ireoidismo secundário (HPTS) é uma tarefa desafiadora com diversos fatores que contribuem para o fracasso do tratamento. A terapia calcimimética revolucionou o manejo do HPTS, levando a alterações nas indicações e no momento apropriado da paratireoidectomia (PTX) em todo o mundo. Métodos: Comparamos taxas de resposta às abordagens clínica vs. cirúrgica do HPTS em pacientes em diálise de manutenção (DRC 5D) e pacientes transplantados renais (TxR). Foi realizada uma análise retrospectiva dos achados de um ano de acompanhamento. Pacientes com DRC 5D foram divididos em 3 grupos de acordo com a estratégia de tratamento: paratireoidectomia, manejo clínico sem cinacalcete (denominado padrão - P) e com cinacalcete (P + CIN). Os pacientes com TxR foram divididos em 3 grupos: PTX, CIN (uso de cinacalcete) e observação (OBS). Resultados: Na DRC 5D, encontramos uma redução significativa do paratormônio (PTH) em todos os grupos. Apesar de todos os grupos apresentarem um PTH mais elevado no início do estudo, identificamos uma redução mais acentuada no grupo PTX. Com relação ao HPTS grave, a diferença entre os grupos foi evidentemente maior: 31%, 14% e 80% dos grupos P, P + CIN e PTX atingiram níveis adequados de PTH, respectivamente (p< 0,0001). Com relação à população TxR, embora a diferença não tenha sido tão impressionante, também foi observada uma taxa maior de sucesso no grupo PTX. Conclusão: A PTX ainda parece ser a melhor escolha de tratamento para o HPTS, especialmente em pacientes com doenças prolongadas em cenários sem recursos.

Atingimento das Metas de Colesterol LDL em Pacientes com Histórico de Infarto Agudo do Miocárdio: Estudo Transversal do Mundo Real / Attainment of LDL-Cholesterol Goals in Patients with Previous Myocardial Infarction: A Real-World Cross-Sectional Analysis

Resumo Fundamento: As diretrizes da Sociedade Europeia de Cardiologia recomendam um nível de colesterol LDL (LDL-C) < 55 mg/dL para pacientes com doença cardiovascular estabelecida. Embora a fórmula de Friedewald ainda seja amplamente utilizada para estimar o LDL-C, a fórmula mais recente de Martin-Hopkins mostrou maior precisão. Objetivos: Nosso objetivo foi avaliar: A) a proporção de pacientes que atingiram a meta de LDL-C e as terapias utilizadas em um centro terciário; B) o impacto da utilização do método de Martin-Hopkins em vez do método de Friedewald na proporção de pacientes controlados. Métodos: Estudo transversal monocêntrico, incluindo pacientes consecutivos pós-infarto do miocárdio, acompanhados por 20 cardiologistas, em um hospital terciário. Os dados foram coletados retrospectivamente de consultas clínicas realizadas após abril de 2022. Para cada paciente, os níveis de LDL-C e o atingimento das metas foram estimados a partir de um perfil lipídico ambulatorial, utilizando as fórmulas de Friedewald e Martin-Hopkins. Um valor-p bicaudal < 0,05 foi considerado estatisticamente significativo para todos os testes. Resultados: Foram incluídos 400 pacientes (com 67 ± 13 anos, 77% do sexo masculino). Utilizando a fórmula de Friedewald, a mediana de LDL-C sob terapia foi de 64 (50-81) mg/dL, e 31% tinham LDL-C dentro da meta. Estatinas de alta intensidade foram usadas em 64% dos pacientes, 37% estavam em uso de ezetimiba e 0,5% estavam em uso de inibidores de PCSK9. A terapia combinada de estatina de alta intensidade + ezetimiba foi utilizada em 102 pacientes (26%). A aplicação do método de Martin-Hopkins reclassificaria um total de 31 pacientes (7,8%). Entre aqueles considerados controlados pela fórmula de Friedewald, 27 (21,6%) teriam LDL-C estimado por Martin-Hopkins acima da meta. Conclusões: Menos de um terço dos pacientes pós-infarto do miocárdio apresentaram LDL-C dentro da meta. A aplicação da fórmula de Martin-Hopkins reclassificaria um quinto dos pacientes presumivelmente controlados no grupo de pacientes não controlados.

Abstract Background: The European Society of Cardiology guidelines recommend an LDL-cholesterol (LDL-C) < 55 mg/dL for patients with established cardiovascular disease. While the Friedewald equation to estimate LDL-C is still widely used, the newer Martin-Hopkins equation has shown greater accuracy. Objectives: We aimed to assess: A) the proportion of patients reaching LDL-C goal and the therapies used in a tertiary center; B) the impact of using the Martin-Hopkins method instead of Friedewald's on the proportion of controlled patients. Methods: A single-center cross-sectional study including consecutive post-myocardial infarction patients followed by 20 cardiologists in a tertiary hospital. Data was collected retrospectively from clinical appointments that took place after April 2022. For each patient, the LDL-C levels and attainment of goals were estimated from an ambulatory lipid profile using both Friedewald and Martin-Hopkins equations. A two-tailed p-value of < 0.05 was considered statistically significant for all tests. Results: Overall, 400 patients were included (aged 67 ± 13 years, 77% male). Using Friedewald's equation, the median LDL-C under therapy was 64 (50-81) mg/dL, and 31% had LDL-C within goals. High-intensity statins were used in 64% of patients, 37% were on ezetimibe, and 0.5% were under PCSK9 inhibitors. Combination therapy of high-intensity statin + ezetimibe was used in 102 patients (26%). Applying the Martin-Hopkins method would reclassify a total of 31 patients (7.8%). Among those deemed controlled by Friedewald's equation, 27 (21.6%) would have a Martin-Hopkins' LDL-C above goals. Conclusions: Less than one-third of post-myocardial infarction patients had LDL-C within the goal. Applying the Martin-Hopkins equation would reclassify one-fifth of presumably controlled patients into the non-controlled group.

Seasonal effect on phenolic content and antioxidant activity of young, mature and senescent leaves from Anredera cordifolia (Ten. ) Steenis (Basellaceae) / Efeito sazonal no conteúdo de fenólicos e ação antioxidante de folhas jovens, maduras e senescentes de Anredera cordifolia (Ten. ) Steenis (Basellaceae)

Anredera cordifolia (Ten.) Steenis is a vine species native to Brazil that is considered an unconventional food plant and a medicinal species whose phenolic compounds exert antioxidant activity. Since the production of metabolites is determined by environmental factors and leaf maturity, it is important to track these changes in order to determine the best time to harvest. This study aimed to verify whether leaf phenology and seasonality cause variations in the amount of phenolic compounds and in the antioxidant activity of this species. The leaves were collected in different seasons between September 2018 and April 2019, and separated according to maturity: young, mature, and senescent. Daily atmospheric temperature and rainfall data were used to characterize the collection period. The total phenolic content (TPC), determined by Folin-Ciocalteu method, was significantly higher in the young leaves collected in winter, a season of lower temperatures. These leaves showed 54.4 mg of gallic acid equivalents per 100 g of dry matter (mg GAE 100 g-1DM). Other results averaged 25.6 mg GAE 100 g-1DM. The highest antioxidant activity, assessed via the 2,2-diphenyl-1-picrylhydrazyl (DPPH) method, regardless of leaf phenology, was observed in leaves harvested in autumn (73.7%) and winter (71.1%), seasons with lower rainfall. Leaves harvested in summer and spring had lower antioxidant action rates (54.3 e 37.5%, respectively). There was no significant correlation between the total phenolic content and antioxidant activity. Thus, the phenolic composition of A. cordifolia, and consequently its activity on free radicals, varies seasonally in response to temperature and rainfall, and may or may not interact with the age of the leaves.

Anredera cordifolia (Ten.) Steenis é uma trepadeira nativa do Brasil considerada uma planta alimentícia não convencional e uma espécie medicinal, cujos compostos fenólicos exercem ação antioxidante. Como a produção de metabólitos é determinada por fatores ambientais e pela maturidade das folhas, é importante acompanhar essas mudanças a fim de determinar a época de colheita. Neste estudo objetivou-se verificar se a fenologia foliar e a sazonalidade ocasionam variação na quantidade de compostos fenólicos e na ação antioxidante dessa espécie. As folhas foram coletadas em diferentes estações, entre setembro de 2018 e abril de 2019, e separadas conforme a maturidade: jovens, maduras e senescentes. Os dados diários de temperatura atmosférica e pluviosidade foram usados para caracterizar o período de coleta. O conteúdo de fenólicos totais (TPC), determinado pelo método Folin-Ciocalteu, foi significativamente maior nas folhas jovens coletadas no inverno, período caracterizado por temperaturas mais baixas. Estas folhas apresentaram 54,4 mg equivalentes de ácido gálico por 100 g de matéria seca (mg GAE 100 g-1DM) . A média dos outros resultados foi de 25,6 mg GAE 100 g-1DM. A maior ação antioxidante, avaliada pelo método do radical livre 2,2-difenil-1-picrilhidrazil (DPPH), foi observada em folhas colhidas no outono (73,7%) e inverno (71,1%), independentemente da fenologia foliar. Nestes períodos a pluviosidade foi menor. Folhas colhidas no verão e na primavera apresentaram menores percentuais de ação antioxidante (54,3 e 37,5%, respectivamente). Não houve correlação significativa entre o conteúdo de fenólicos totais e a atividade antioxidante. Conclui-se que a composição fenólica de A. cordifolia e, consequentemente, sua ação sobre radicais livres, varia sazonalmente em resposta à temperatura e pluviosidade, podendo ou não interagir com a idade das folhas.

Bilateral choroidal metastasis of follicular thyroid carcinoma 7 years after total thyroidectomy: a case report

ABSTRACT Follicular thyroid cancers account for 15%-20% of all thyroid tumors. Choroidal metastases secondary to follicular thyroid cancer rarely occur. Herein, we report the case of an 85-year-old woman who presented choroidal metastasis from a follicular thyroid carcinoma in the right eye 7 years after total thyroidectomy and underwent enucleation. To confirm the diagnosis and primary tumor site, histopathological, and immunohistochemical examinations were performed. One year later, she presented metastasis in the contralateral eye. Few similar cases have been described in the literature.

Atendimento odontológico de pacientes com necessidades especiais na atenção secundária em um estado do nordeste do Brasil / Dental care of special needs patients in secondary care in a northeastern state of Brazil / Atención odontológica a pacientes con necesidades especiales en la atención secundaria en un estado del nordeste de Brasil

O objetivo desse estudo foi descrever a produção dos atendimentos oferecidos aos pacientes com necessidades especiais nos Centros de Especialidades Odontológicas (CEO) da Paraíba (Brasil) e sua relação com o cumprimento das metas de produtividade, entre o período de 2019 e 2022. Trata-se de um estudo descritivo e ecológico em que foram coletados dados secundários do Sistema de Informações Ambulatoriais do SUS (SIA/SUS), através da captação da produção ambulatorial individualizada (BPA-I), por meio da ferramenta TabWin, dos 98 CEO operantes na Paraíba. Realizou-se análise descritiva e analítica, por meio dos testes Qui-Quadrado de Pearson e Exato de Fisher entre a variável dependente "alcance da meta" e a variável independente "adesão à Rede de Cuidados à Pessoa com Deficiência (RCPD)". Em todos os anos, a porcentagem de CEO cumpridores da meta (15,3% em 2019; 1% em 2020; 12,2% em 2021; e 11,2% em 2022) foi substancialmente menor que os números expressados por aqueles que não alcançaram a produção mínima. Os resultados também apontaram maior realização de procedimentos restauradores (29,6% em 2019; 28,6% em 2020; 32,7% em 2021; e 37,8% em 2022) em detrimento aos periodontais, cirúrgicos e preventivos. No que concerne a estar aderido à RCPD, no ano de 2022, 90,9% dos CEO que alcançaram a meta estavam aderidos à Rede (p<0,05). Concluiu-se que uma baixa frequência de CEO alcançou o cumprimento da meta de produtividade da especialidade de Odontologia para Pacientes com Necessidades Especiais nos CEO. No entanto, a adesão à RCPD manifestou-se como elemento influenciador para aqueles que cumpriram suas metas mensais e anuais.

The objective of this study was to describe the production of care provided to special needs patients in the Dental Specialties Centers (CEO) of Paraíba (Brazil) and its relationship with the achievement of productivity goals, between the period 2019 and 2022. This is a descriptive and ecological study in which secondary data were collected from the SUS Outpatient Information System (SIA/SUS), by capturing the individualized outpatient production (BPA-I), through the TabWin tool, of the 98 operating CEOs in Paraíba. We carried out descriptive and analytical analysis, using Pearson's Chi-square and Fisher's Exact tests between the dependent variable "goal attainment" and the independent variable "adherence to the Care Network for People with Disabilities (RCPD)". In all years, the percentage of CEOs meeting the goal (15.3% in 2019; 1% in 2020; 12.2% in 2021; and 11.2% in 2022) was substantially lower than the numbers expressed by those who did not meet the minimum output. The results also indicated greater performance of restorative procedures (29.6% in 2019; 28.6% in 2020; 32.7% in 2021; and 37.8% in 2022) to the detriment of periodontal, surgical, and preventive procedures. Regarding being adhered to the RCPD, in the year 2022, 90.9% of the CEOs who reached the goal were adhered to the Network (p<0.05). It was concluded that a low frequency of CEOs achieved compliance with the productivity target of the specialty of Dentistry for Special Needs Patients in CEOs. However, adherence to the RCPD manifested itself as an influential element for those who met their monthly and annual goals.

Los resultados también indicaron una mayor realización de procedimientos restauradores (29,6% en 2019; 28,6% en 2020; 32,7% en 2021; y 37,8% en 2022) en detrimento de los procedimientos periodontales, quirúrgicos y preventivos. Respecto a estar adherido a la RCPD, en el año 2022, el 90,9% de los CEOs que alcanzaron el objetivo estaban adheridos a la Red (p<0,05). Se concluyó que una baja frecuencia de CEOs alcanzó el cumplimiento de la meta de productividad de la especialidad de Odontología para Pacientes con Necesidades Especiales en CEOs. Sin embargo, la adhesión al RCPD se manifestó como un elemento influyente para aquellos que cumplieron sus objetivos mensuales y anuales.

Dental age estimation by assessing the pulp volume of five teeth in a peruvian population using cone beam computed tomography images / Estimación de la edad dental evaluando el volumen pulpar de cinco dientes utilizando imágenes de tomografías computarizadas de haz cónico en una población peruana

Abstract Dental age estimation is very important for individual identification in criminal and civil forensic investigations. One of the methods for age estimation is studying age related changes in pulp volume of teeth. The objective of the current study was to estimate dental age from the pulp volume of five different categories of teeth of a Peruvian sample using cone beam computed tomography (CBCT). Retrospective CBCT records of 231 patients (females (134), males (97), age: 12-60 years) were included in the study, categorized into five different age groups (12-19, 20-29, 30-39, 40-49, 50-59, 60 years and older). Dental pulp volume of five categories of teeth(upper canines, left upper central incisors, left upper first molars, lower left first premolars, first molars) were analyzed using Romexis® 5.3.3.5 software for each patient. There was a reduction in the pulp volume of upper right and left canine with age. The Pulp volume was lowest in people aged 60 years and over. Linear regression analysis of the pulp volume and chronological age showed a coefficient of determination of 30%, suggesting a weak correlation. A weak correlation between dental pulp and age is derived. But, a robust large homogenous sample of teeth in future for different age groups may establish a reliable regression equation.

Resumen La estimación de la edad dental en personas vivas y cadáveres es muy importante para la Odontología Forense, sobre todo en casos de identificación en investigaciones legales y sociales. El objetivo del estudio fue estimación de la edad dental mediante la medición del volumen pulpar de imágenes dentales en tomografía computarizada de haz cónico (TCHC) de pacientes peruanos. Fueron analizadas 231 TCHC de pacientes entre 12 a 60 años a más. (Mujeres (134), hombres (97)) se dividieron en seis grupos de edad (12-19, 20-29, 30-39, 40-49, 50-59, 60 años a más). El análisis volumétrico de la pulpa dental se realizó en un total de 1155 dientes (caninos superiores, incisivos centrales superiores izquierdos, primeros molares superiores izquierdos y primeros premolares inferiores izquierdos), mediante el software Romexis® 5.3.3.5. El análisis de regresión lineal mostró un coeficiente de determinación del 30% que sugiere una correlación débil entre la relación del volumen pulpar de los dientes y la edad. El volumen pulpar de los caninos superiores derecho e izquierdo disminuyó a medida que aumentaba la edad y el volumen pulpar en dientes de personas de 60 años a más fue el más bajo. Sin embargo, se pueden proponer estudios futuros para incluir una gran muestra homogénea de dientes en diferentes categorías y grupos de edad para confirmar la correlación y establecer una ecuación de regresión confiable.

Trichoderma spp., una alternativa para la agricultura sostenible: una revisión

En la actualidad uno de los retos a los que se enfrentan los agricultores es producir alimentos bajo las inclemencias climáticas. Para el 2050, se estima un aumento en la demanda en producción de alimentos básicos a causa del incremento demográfico, aumentando con ello el detrimento de los recursos naturales. Dentro de las alternativas biológicas está el uso de insumos a base de microorganismos benéficos, como el género Trichoderma. Los cuales se han utilizado en los campos agrícolas para el control biológico contra un gran número de fitopatógenos. Sin embargo, aún son poco conocidas otras propiedades benéficas de este género para las plantas que coloniza y el ecosistema. Se realizó una búsqueda de artículos científicos en Academic Search Ultimate, BioOne, Acsess, Esmerald, Fuente Académica, ScienceDirect y Springer, entre 2015 y 2023, con dos excepciones de años anteriores. Se utilizó la palabra clave "Trichoderma" y aquellas relacionadas con interacciones microbianas y su aplicación agrícola. Esta revisión resume los hallazgos bibliográficos actuales de este género que muestran su alta capacidad hacia el desarrollo sostenible de los agroecosistemas. Varias investigaciones reportan su capacidad de inducir la defensa vegetal, la promoción del crecimiento y desarrollo radicular, así como la estimulación y síntesis de sustancias que contribuyen a fortalecer la fertilidad del suelo. Con ello mejora los rendimientos de los cultivos a los que se encuentra asociado. En definitiva, la aplicación de Trichoderma puede coadyuvar a disminuir los efectos negativos ocasionados por el uso de agroquímicos y fertilizantes sintéticos, contribuyendo a una producción más sostenible.

Currently, one of the most critical challenges facing farmers is the production of food under adverse weather conditions. By 2050, an increase in the production of staple foods is estimated due to demographics, thereby increasing the depletion of natural resources. Among the biological alternatives is the use of inputs based on beneficial microorganisms such as the Trichoderma genus, which have been used in agricultural fields for biological control against a large number of phytopathogens. However, other beneficial properties of this genus for the plants it colonizes, and the ecosystem are still little known. Therefore, a search for scientific articles was carried out in Academic Search Ultimate, BioOne, Acsess, Esmerald, Fuente Academic, ScienceDirect and Springer, between 2015 and 2023, with two exceptions from previous years. The keyword "Trichoderma" was used and those related to microbial interactions and their agricultural application. Therefore, this review summarizes the current bibliographic findings of this genus, that shows its high capacity towards the sustainable development of agroecosystems. Several investigations report its ability to induce plant defense, promote growth and root development, and stimulate and synthesize substances that help strengthen soil fertility. This improves the yields of the crops to which they are associated. With this, the application of Trichoderma can reduce the negative effects caused by the use of agrochemicals and synthetic fertilizers, contributing to a more sustainable production.

Sentido de comunidad de adolescentes en escuelas y barrios durante el covid-19

(analítico) El sentido de comunidad de jóvenes es la sensación de pertenencia de este grupo en relación con la escuela o el barrio. Es un tema estudiado en las ciencias sociales, aunque sus transformaciones no han sido suficientemente visibilizadas. El propósito del estudio es describir las percepciones del sentido de comunidad en la escuela y el barrio durante el covid-19 en estudiantes de 14 a 18 años de escuelas públicas, subvencionadas y privadas en la Región Metropolitana de Chile. Con metodología cualitativa, descriptiva y transversal, desde la fotoprovocación virtual, se analizan temáticamente las perspectivas juveniles. Los resultados muestran que el sentido de comunidad escolar está tensionando el relacionamiento interpersonal, emergiendo afectos negativos y destacando la pertenencia al espacio físico. El sentido de comunidad en el barrio es incipiente durante la pandemia.

(analytical) Sense of community for young people is a feeling of belonging in relation to school or the neighborhood. It is a topic that has been extensively studied in the social sciences, even though transformations of this knowledge have not been sufficiently visible. The purpose of this research was to describe perceptions of the sense of community at school and in the neighborhood during COVID-19 among students aged 14 to 18 from public, semi-public and private schools in the Metropolitan Region of Santiago. Using a qualitative, descriptive, and cross-sectional methodology that involved digital photo-stimuli, youth perspectives were analyzed thematically. The results show that young people's sense of community in schools during the pandemic involved strained interpersonal relationships with negative affects emerging. The participating young people highlighted the importance of physical space in relation to their sense of belonging. The young people's sense of community in the neighborhood was incipient during the pandemic.

(analítico) O senso de comunidade dos jovens é o sentimento de pertencimento desse grupo em relação à escola ou ao bairro.

O objetivo do estudo é descrever as percepções do senso de comunidade na escola e no bairro durante o Covid-19 em alunos de 14 a 18 anos de escolas públicas, subsidiadas e privadas da Região Metropolitana do Chile. Com metodologia qualitativa, descritiva e transversal, a partir da fotoprovocação virtual, as perspectivas juvenis são analisadas tematicamente. Os resultados mostram que o sentido de comunidade escolar é acentuar o relacionamento interpessoal, emergindo afetos negativos e destacando o pertencimento ao espaço físico. O senso de comunidade no bairro é incipiente durante a pandemia.

Cross-cultural adaptation of the Science Motivation Questionnaire II (SMQ-II) for Portuguese-speaking Brazilian secondary school students

Introduction: Science motivation is important for students' scientific literacy. Yet, there is a lack of valid and reliable measurement tools for the Brazilian context. This study presents the Brazilian Portuguese version of the Science Motivation Questionnaire (SMQ-II) and motivational baseline data. Method: The instrument was translated into Brazilian Portuguese using cross-cultural validation procedures. For structural validity evidence, the responses of 646 secondary school students were subjected to exploratory and confirmatory factor analysis, as well as measurement invariance. For reliability evidence, Cronbach's alpha (a) and McDonald's omega (w) were calculated. Students' motivation was analysed using 2 (gender) x 4 (grade levels) x 3 (study modality) MANOVA. Results: 24 items measuring intrinsic motivation, career motivation, grade motivation, and self-efficacy supported a four-factor structure with adequate reliability against the original five-factor structure (self-determination was not salient). Measurement invariance was established across the gender and study modalities, but not for grade levels. Higher-grade level Brazilian students were less motivated, and girls reported higher intrinsic and career motivation, but lower self-efficacy than boys. Conclusion: These findings lay the foundation for the assessment of Brazilian students' science motivation, although they also reveal problems in the latent structure of the SMQ-II and call for the development of instruments rooted in contemporary motivational theories.

Introdução: A motivação científica é importante para a alfabetização científica dos estudantes. No entanto, há uma falta de ferramentas de medição válidas e confiáveis para o contexto brasileiro. Este estudo apresenta a versão em português brasileiro do Questionário de Motivação Científica (SMQ-II) e dados de base motivacionais. Método: O instrumento foi traduzido para o português brasileiro utilizando procedimentos de validação transcultural. Para construir provas de validade, as respostas de 646 alunos do ensino médio foram submetidas à análise exploratória e confirmatória de fatores, bem como invariância de medidas. Para a evidência de confiabilidade, foram calculados o alfa de Cronbach (a) e o ômega de McDonald's (w). A motivação dos estudantes foi analisada usando 2 (gênero) x 4 (notas) x 3 (modalidade de estudo) MANOVA. Resultados: 24 itens medindo a motivação intrínseca, motivação de carreira, motivação de grau e auto-eficácia suportaram uma estrutura de quatro fatores com confiabilidade adequada contra a estrutura original de cinco fatores (a autodeterminação não foi saliente). A invariância da medição foi estabelecida através de gênero e modalidade de estudo, mas não para o nível de nota. Os estudantes brasileiros de grau superior estavam menos motivados, e as meninas relataram maior motivação intrínseca e de carreira, mas menor auto-eficácia do que os meninos. Conclusão: Estas descobertas abrem o caminho para a avaliação da motivação científica dos estudantes brasileiros, mas também revelam problemas na estrutura latente do SMQ-II e exigem o desenvolvimento de instrumentos enraizados em teorias motivacionais contemporâneas.

Psychometric properties of the Entrepreneurial Intention Questionnaire (EIQ) in Dominican Republic adolescents

Introduction: This work represents the first attempt to obtain evidence of the validity of an entrepreneurial intention questionnaire in the adolescent population of a Latin American or Caribbean country. The objectives are to study the factor structure, the reliability, the external validity and to test the gender invariance of the Entrepreneurial Intention Questionnaire, in its adaptation for adolescents. Method: The sample consisted of 708 adolescents from the Dominican Republic with a mean age of 15.49, 65.2% of whom were women and 35.8% were men. Analyses included confirmatory factor analysis, Cronbach's Alpha and Omega scores for reliability, correlations, and a gender invariance routine. Finally, latent means of females and males are compared. Results: The confirmatory factor analysis showed a good fit to the data and the reliability results were adequate. In addition, the correlations with the Entrepreneurial Attitudes Scale for Students were positive and statistically significant. Also, strict gender invariance was successfully verified. Although males presented a higher subjective norm, females showed higher entrepreneurial intentions. Conclusions: The Entrepreneurial Intention Questionnaire shows adequate psychometric properties and proves useful in conducting research on the promotion of entrepreneurship in early stages.

Movilidades y experiencia escolar en la periferia urbana de Córdoba, Argentina / Mobilities and School Experience in the Urban Periphery of Córdoba, Argentina / Mobilidades e Experiência Escolar na Periferia Urbana de Córdoba, Argentina

(analítico) Se analizan las intersecciones entre territorio, movilidades y experiencias educativas de jóvenes de un barrio periférico de la ciudad de Córdoba, Argentina. A partir de un abordaje etnográfico, basado en observaciones, talleres de mapeo territorial y entrevistas grupales con estudiantes de nivel secundario, damos cuenta de una monopolización de tiempos y espacios por parte de la escuela, que inhibe su participación en otras esferas sociales significativas. Desde la perspectiva juvenil, la escuela asume una connotación paradojal: es un «buen lugar» para estar, aunque también un ámbito que no satisface demandas específicas relativas a la salud, el respeto a la diversidad y el reconocimiento. El papel de las/os educadoras/es no es impugnado, tanto como el modo en que muchas/os están pudiendo hacer frente a dichas demandas.

(analytical) This paper analyzes the intersections between territory, mobilities, and educational experiences of youngsters from a peripheral neighborhood in the city of Córdoba, Argentina. Through an ethno-graphic approach based on observations, territorial mapping workshops, and group interviews with secondary level students, we account for a monopolization of time and space by the school, which inhibits their participation in other significant social spheres. From the youth perspective, the school assumes a paradoxical connotation: it is a «good place» to be, although it is also an environment that does not meet specific demands related to health, respect for diversity, and recognition. The role of educators is not contested, as much as the way in which many of them are able to meet these demands.

(analítico) O trabalho analisa as interseções entre território, mobilidade e experiências educacionais de jovens de um bairro periférico da cidade de Córdoba, Argentina. Através de uma abordagem etnográfica baseada em observações, oficinas de mapeamento territorial e entrevistas em grupo com estudantes do ensino medio, reconhecemos uma monopolização do tempo e do espaço pela escola, o que inibe sua participação em outras esferas sociais significativas. Do ponto de vista dos jovens, a escola assume uma conotação paradoxal: é um «bom lugar» para estar, embora também seja um ambiente que não atende às demandas específicas relacionadas à saúde, respeito à diversidade e reconhecimento. O papel dos educadores não é contestado, assim como a maneira como muitos deles estão lidando com essas demandas.

Introducción: El ictus isquémico representa la tercera causa de mortalidad en el mundo y la primera causa de discapacidad. Objetivos: Describir los efectos beneficiosos de la prescripción de las estatinas en la prevención primaria, secundaria y terciaria del ictus isquémico. Métodos: Se realizó una revisión bibliográfica sobre la prescripción de estatinas en la prevención primaria, secundaria y terciaria del ictus isquémico. Se revisaron más de 400 artículos publicados en PubMed, Cochrane y Medline. Conclusiones: El empleo de estatinas disminuye la mortalidad en la prevención primaria y secundaria, se utiliza precozmente en la fase aguda (prevención terciaria), disminuye el área infartada, existe una mejoría clínica y disminuyen los reactantes de la fase aguda como la proteína C reactiva.

Introduction: Ischemic stroke represents the third cause of mortality worldwide and the first cause of disability. Objective: To describe the beneficial effects of the prescription of statins in the primary, secondary and tertiary prevention of ischemic stroke. Methods: A bibliographic review on the prescription of statins in the primary, secondary and tertiary prevention of ischemic stroke was carried out. More than 400 articles published in MEDLINE/PubMed and Cochrane were reviewed. Only 50 articles met the selection criteria, which were published from May 2021 to June 2022. Conclusions: The use of statins decreases mortality in primary and secondary prevention. If they are used early in the acute phase (tertiary prevention), the infarcted area decreases, there is clinical improvement and acute phase reactants such as C-reactive protein decrease.

Introducción: La hipertensión arterial constituye un problema de salud pública en casi todo el mundo. Entre los factores de riesgo vinculados a ella se destaca la acumulación de grasa, que puede, a su vez, establecer los riesgos, las comorbilidades y la mortalidad asociados a esta entidad nosológica. Objetivo: Determinar las variaciones de los valores del perímetro abdominal y el índice cintura-cadera en pacientes con hipertensión arterial, según variables epidemiológicas y clínicas seleccionadas. Métodos: Se realizó un estudio descriptivo, prospectivo y transversal de 221 pacientes con hipertensión arterial, pertenecientes al Consultorio 19 del Policlínico Docente Josué País García del municipio de Santiago de Cuba, desde junio del 2019 hasta diciembre del 2020. Resultados: Predominó el sexo femenino y el grupo etario de 65-74 años (28,5 %). Los indicadores antropométricos perímetro abdominal e índice cintura-cadera tuvieron valores que superaron los parámetros normales establecidos para ambos sexos. El cálculo del perímetro abdominal reveló un predominio de la obesidad en el sexo femenino, en tanto se clasificó como aumentado en el sexo masculino. Conclusiones: Los valores del índice cintura-cadera y del perímetro abdominal en ambos sexos estuvieron por encima de los clasificados por la Organización Mundial de la Salud como de alto riesgo de presentar la enfermedad.

Introduction: Hypertension constitutes a problem of public health in almost all over the world. Among the risk factors associated with it, the accumulation of fat is notable, which can, in turn, establish risks and determine comorbidities and mortality associated with this nosological entity. Objective: To determine the variations in the values of the abdominal perimeter and waist-hip ratio in patients with hypertension, according to selected epidemiological and clinical variables. Methods: A descriptive, prospective and cross-sectional study was carried out on 221 patients with hypertension, belonging to doctor's office 19 of Josué País García Teaching Polyclinic in Santiago de Cuba municipality, from June, 2019 to December, 2020.

A significant increase of the gluteal projection after the intervention was observed (α =0.05) and the results were good in most of the members of the sample (84.0%). Conclusions: The augmentation gluteoplasty with intramuscular implants is a safe procedure and offers favorable aesthetic results.

Secondary amyloidosis with concomitant gastric GIST and gastric adenocarcinoma - A case report

Secondary amyloidosis is a well-established entity and has been described in association with chronic inflammatory conditions such as rheumatoid arthritis, ankylosing spondylitis, bronchiectasis, tuberculosis, etc., It has also been reported in association with neoplasms such as Hodgkin's lymphoma, Waldenstrom's macroglobulinemia, renal cell carcinoma, lung carcinoma, etc. However, only a few case reports documenting the association of amyloidosis with gastrointestinal tumor (GIST) and gastric adenocarcinoma are available in the literature. Hereby, we report a case of a 74-year-old male who presented with colicky abdominal pain and vomiting. Ultrasonography revealed a common bile duct (CBD) stone and a small extra-luminal gastric mass. Endoscopic retrograde cholangiopancreatography (ERCP) was performed to remove the CBD stone which revealed an incidental finding of gastric ulcer. A biopsy was taken from the gastric ulcer which on histopathological examination was confirmed as adenocarcinoma leading onto total gastrectomy. During total gastrectomy, an inadvertent injury to the spleen led to simultaneous splenectomy. Multiple samples from the gastric ulcer, the extra-luminal gastric mass, and the spleen were subjected to histopathological examination. Gastric ulcer was confirmed as adenocarcinoma, gastric extra-luminal mass was confirmed as GIST, and splenic examination revealed widespread deposition of amyloid which on Congo-red stain imparted an apple-green birefringence on polarizing microscopy. To the best of our knowledge, this is the first-ever case of such an association where gastric adenocarcinoma occurred with concomitant gastric GIST and secondary amyloidosis of the spleen.
