RESUMEN Para lograr los objetivos planteados en su Plan Nacional de desarrollo económico y social hasta el 2030, Cuba necesita tener una estructura productiva sólida,diversificada, articulada y que se complemente. Representa un reto para el país, hacer los cambios previstos en la Conceptualización del modelo de desarrollo económico y social cubano para adaptarse a las actuales dinámicas y requerimientos del desarrollo económico internacional. El artículo tiene como objetivo evaluar la actual estructura productiva, midiendo la importancia relativa y complementariedad de los sectores en la economía nacional, en base a indicadores seleccionados del Sistema de Cuentas Nacionales. Los principales resultados reflejan desequilibrios y poca complementariedad sectoriales, bajos encadenamientos productivos, asimetrías en el desarrollo de las provincias y producciones exportables de baja complejidad con escaso valor agregado.

ABSTRACT In order to achieve the objectives set out in its National Economic and Social Development Plan through 2030, Cuba needs to have a solid, diversified, articulated and complementary productive structure. It represents a challenge for the country to make the changes foreseen in the Conceptualization of the Cuban economic and social development model to adapt the current dynamics and requirements of international economic development. The objective of the paper is to evaluate the current productive structure, measuring the relative importance and complementarity of the sectors in national economy, based on indicators of the National Accounts System. The main results reflect sectoral imbalances and small sectoral complementarity, low productive linkages, asymmetries development of provinces, low complexity exportable products with limited added value.

Abstract This research is undertaken, motivated by the need to unravel the progression of learning models, which have been adapting to meet the demands of society in its constant dynamics of fluctuation and transformation. The aim of this work is to systematically examine the evolution of learning models, highlighting the paradigmatic changes that have favored the transition from traditional learning approaches to more innovative and transdisciplinary proposals. To achieve this, a bibliographic analysis is carried out, supported by the hermeneutic method for the contextual interpretation of literature and discourses, in order to unravel the complexities inherent in the evolution of learning models. The results highlight the limiting influence of the simplicity paradigm in traditional educational formation and the need for a shift towards dialogicity and disciplinary collaboration and integration to advance towards complexity. It concludes by arguing in favor of adopting the complexity paradigm, advocating for a transdisciplinary epistemology and an interstructuring approach to learning, which allow for integral human development. Recognizing human complexity in teaching and learning demands a radical transformation of education towards more holistic and transformative practices, essential for building an equitable and just society.

Resumen Esta investigación se emprende motivada por la necesidad de desentrañar la progresión de los modelos de aprendizaje, los cuales se han ido adaptando para responder a las demandas de la sociedad en su dinámica constante de fluctuación y transformaciones. El objetivo de este trabajo es examinar de forma sistemática la evolución de los modelos de aprendizaje, destacando los cambios paradigmáticos que han favorecido la transición de enfoques de aprendizaje tradicionales hacia propuestas más innovadoras y transdisciplinarias. Para lograrlo, se lleva a cabo un análisis bibliográfico apoyado en el método hermenéutico para la interpretación contextual de la literatura y los discursos, a fin de desentrañar las complejidades inherentes en la evolución de los modelos de aprendizaje. Los resultados resaltan la influencia limitante del paradigma de la simplicidad en la formación educativa tradicional y la necesidad de un giro hacia la dialogicidad y la colaboración e integración disciplinaria para avanzar hacia la complejidad. Se concluye argumentando a favor de la adopción del paradigma de la complejidad, abogando por una epistemología transdisciplinaria y un enfoque de aprendizaje interestructurante, que permitan el desarrollo humano integral. El reconocimiento de la complejidad humana en la enseñanza y el aprendizaje exige una transformación radical de la educación hacia prácticas más holísticas y transformadoras, esenciales para construir una sociedad equitativa y justa.

The training of creative computer professionals is considered a strategic process in different countries as it is essential for the informatization of society. This article proposes an approach to the creative learning of computer science for the digital transformation of modern society. The objective of the research was to evaluate the creative learning of computer science during the training of computer professionals. An instrument derived from previous research and metrics was applied to evaluate creative learning in the two groups of terminal years of the Computer Engineering career at the University of Matanzas, Cuba, with a mixed paradigm. Quantitative analyses diagnosed the predominant learning in the career that offer elements to managers to make decisions. The qualitative analyses made it possible to unveil the four stages of formation of creative learning of computer science in the career: pre-university stage, basic stage, professional stage and research stage. In addition, three key factors in the formation of creative learning of computer science were obtained: the integration of subjects, the solution of real projects and the emotional support of teachers and other professionals to students during their insertion in the computerization of organizations.

La formación de profesionales informáticos creativos se considera como un proceso estratégico en diferentes países al resultar esencial para la informatización de la sociedad. El presente artículo plantea un acercamiento al aprendizaje creativo de la informática para la transformación digital de la sociedad moderna. El objetivo de la investigación fue evaluar el aprendizaje creativo de la informática durante la formación de profesionales informáticos. Se aplicó un instrumento derivado de investigaciones anteriores y métricas para evaluar el aprendizaje creativo en los dos grupos de años terminales de la carrera de Ingeniería Informática de la Universidad de Matanzas, Cuba, con un paradigma mixto. Los análisis cuantitativos diagnosticaron el aprendizaje predominante en la carrera que ofrecen elementos a los directivos para tomar decisiones. Por su parte, los análisis cualitativos permitieron develar las cuatro etapas de formación del aprendizaje creativo de la informática en la carrera: etapa preuniversitaria, etapa básica, etapa profesional y etapa de investigación. Además, permitieron obtener tres factores claves en la formación del aprendizaje creativo de la informática: la integración de asignaturas, la solución de proyectos reales y el acompañamiento emocional de los profesores y otros profesionales a los estudiantes durante su inserción en la informatización de organizaciones.

Resumo A infecção por micobactérias não tuberculosas é uma das doenças bacterianas crônicas mais comuns em peixes ornamentais de aquário e parece estar diretamente relacionada a práticas de manejo estressantes. Além disso, também representa potencial zoonótico. Aqui, apresentamos o isolamento e a caracterização de micobactérias não tuberculosas de peixes-anjo de água doce doentes (Pterophyllum scalare) em São Paulo, Brasil. Foram avaliadas nove fêmeas reprodutoras descartadas com sinais de doença. Os peixes exibiam letargia, perda de apetite, caquexia, úlceras cutâneas e exoftalmia. Na necropsia, quatro peixes apresentaram granulomas macroscópicos no baço. Mycobacterium chelonae, M. fortuitum, M. gordonae, M. intracellulare e M. peregrinum foram isolados e identificados por análise de restrição por PCR de hsp65. A análise histopatológica revelou lesões microscópicas compatíveis com micobacteriose, e o bacilo de Mycobacterium foi observado pela coloração de Ziehl-Neelsen. Notavelmente, todas as espécies de Mycobacterium identificadas neste estudo já foram relatadas em pacientes humanos; portanto, animais doentes podem ser uma fonte de infecção para pessoas que manipulam peixes e aquários.

Abstract Nontuberculous mycobacteria infection is one of the most common chronic bacterial diseases in ornamental aquarium fish and appears to be directly related to stressful husbandry practices. Furthermore, it also represents zoonotic potential. Here we present the isolation and characterization of non-tuberculous mycobacteria from diseased freshwater angelfish (Pterophyllum scalare) in São Paulo, Brazil. Nine discarded breeding females with signs of disease were evaluated. The fish exhibited lethargy, loss of appetite, cachexia, skin ulcers, and exophthalmia. At necropsy, four fishes presented macroscopic granulomas in the spleen. Mycobacterium chelonae, M. fortuitum, M. gordonae, M. intracellulare and M. peregrinum were isolated and identified by hsp65 PCR restriction analysis. Histopathological analysis revealed microscopic lesions compatible with mycobacteriosis, and Mycobacterium bacillus were observed by Ziehl-Neelsen stain. Notably, all Mycobacterium species identified in this study have already been reported in human patients; therefore, diseased animals may be a source of infection for people who handle fish and aquariums.

ABSTRACT Objetive: To provide a comprehensive analysis of mortality trends from acute pesticide poisoning in Mexico from 2000 through 2021. Methods: The governmental records of deaths from acute pesticide poisoning were used. The age-standardized years of life lost and aged-standardized mortality rates were estimated. Significant changes in trends of annual percentage change were identified using Joinpoint regression. Results: Between 2000 and 2021, mortality was primarily observed in individuals aged 15 to 19 years. Males were the most affected. Self-inflicted pesticide poisoning was the primary registered reason for death. The age-standardized mortality rate from acute pesticide poisoning was reduced from 2012 to 2021 (APC: -4.4; p=0.003). Conclusion: This report is the first study about the mortality rate from acute pesticide poisoning in Mexico. The results provided evidence to consider in developing laws to prevent acute pesticide poisoning.

RESUMO Objetivo: Fornecer uma análise abrangente das tendências de mortalidade por envenenamento agudo por pesticidas no México de 2000 a 2021. Métodos: Foram usados os registros governamentais de mortes por envenenamento agudo por pesticidas. Foram estimados os anos de vida perdidos estandardizados por idade e as taxas de mortalidade estandardizados por idade. Modificações significativas nas tendências de variação percentual anual foram identificadas usando a regressão Joinpoint. Resultados: Entre 2000 e 2021, a mortalidade foi observada principalmente em indivíduos na faixa etária de 15 a 19 anos. Os homens foram os mais afetados. O envenenamento por pesticida autoinfligido foi o principal motivo de morte registrado. A taxa de mortalidade estandardizada por idade por intoxicação aguda por pesticidas foi reduzida de 2012 a 2021 (Annual Percent Change — APC: -4,4; p=0,003). Conclusão: Este relatório é o primeiro estudo sobre a taxa de mortalidade por intoxicação aguda por pesticidas no México. Os resultados forneceram evidências a serem consideradas no desenvolvimento de leis para prevenir o envenenamento agudo por pesticidas.

■ ABSTRACT Introduction: Fat grafting is an autologous graft of cells from subcutaneous tissue, which can be used as a complementary technique in breast reconstruction. Given this, the cryopreservation of adipose tissue-derived mesenchymal stem cells (ADMSCs) could be a way to collect them in one surgical procedure and after performing fractional fat grafting. Dimethyl sulfoxide (DMSO) is a cryopreservative used in cell research, but it is potentially toxic, which would make it impossible to use cryopreserved ADMSCs in clinical practice. New cellular cryopreservatives, without toxicity, have been described in the experimental scientific literature, such as the substances L-proline and trehalose. Therefore, this work aimed to evaluate the viability of ADMSCs cryopreserved with the combination of L-proline and trehalose over up to 90 days. Method: Experimental study in which lipoaspirate samples were obtained from 9 patients. The cellular fraction was processed and frozen with L-proline (1.5M) + trehalose (0.2M) or with DMSO + fetal bovine serum (FBS) as control. After 30 and 90 days, the samples were thawed, and cell viability was assessed using the MTT technique. Results: The analysis of ADMSCs, after 1 and 3 months of freezing, indicated that samples treated with L-proline + trehalose showed similar viability to those preserved with DMSO and SFB (p=0.444). Conclusion: The association of L-proline and trehalose kept ADMSC viable for 30 and 90 days of freezing, and could be an alternative as a cellular cryopreservative without toxicity and enabling the use of serial fat grafting.

■ RESUMO Introdução: A lipoenxertia é um enxerto autólogo de células do tecido celular subcutâneo, que pode ser utilizada como técnica complementar na reconstrução mamária. Diante disso, a criopreservação de células-tronco mesenquimais provenientes de tecido adiposo (CTDAs) poderia ser uma maneira de realizar a coleta em um tempo cirúrgico e após realizar a lipoenxertia de forma fracionada. O dimetilsulfóxido (DMSO) é um criopreservante utilizado em pesquisas com células, porém é potencialmente tóxico, o que impossibilitaria a utilização de CTDAs criopreservadas na prática clínica. Novos criopreservantes celulares, sem toxicidade, vêm sendo descritos na literatura científica experimental, como as substâncias L-prolina e trealose. Com isso, esse trabalho teve como objetivo avaliar a viabilidade de CTDAs criopreservadas com a combinação de L-prolina e trealose, em um período de até 90 dias. Método: Estudo experimental, no qual foram obtidas amostras de lipoaspirado provenientes de 9 pacientes. A fração celular foi processada e congelada com L-prolina (1,5M) + trealose (0,2M), ou com DMSO + soro fetal bovino (SFB), como controle. Após 30 e 90 dias, as amostras foram descongeladas e a viabilidade celular foi avaliada pela técnica de MTT. Resultados: A análise das CTDAs, após 1 e 3 meses de congelamento, indicou que as amostras tratadas com L-prolina + trealose apresentaram viabilidade semelhante àquelas preservadas com DMSO e SFB (p=0,444). Conclusão: A associação de L-prolina e trealose manteve CTDA viáveis por 30 e 90 dias de congelamento, podendo ser uma alternativa como criopreservante celular sem toxicidade e viabilizando o uso de lipoenxertia seriada.

Abstract We conducted a socio-historical study covering the period 1979-2014 to explore the genesis of LGBT health policy in Bahia, Brazil, drawing on Pinell’s theoretical framework for the sociological analysis of public policy. To analyze the social space, we investigated the trajectories of the agents involved in policy formulation and the relations between these agents and the national social space and field of State power. The agents were predominantly from the scientific, human rights, sexual rights, feminism and AIDS fields, and had a high level of bureaucratic and militant capital, meaning they were well-versed in LGBT health issues. The historical conditions of possibility underlying the formulation of LGBT health policy included the formalization of the State Technical Committee on LGBT Health in 2014, in an effort to improve access to comprehensive health care for vulnerable groups; and the Bahia without Homophobia plan, which helped expand dialogue around with civil society and social movements and address the main criticisms of policy making.

Resumo Com o objetivo de descrever a gênese de propostas para a saúde da população de LGBT na Bahia, foi realizado um estudo sócio histórico entre 1979 e 2014. Adotou-se as proposições de Patrice Pinell para a análise sociológica de políticas públicas. A análise do espaço social compreendeu a identificação das trajetórias dos agentes envolvidos com as propostas no estado da Bahia e as relações entre esses agentes e o espaço social nacional, assim como, o campo do poder do Estado. Na Bahia, destacaram-se agentes com trajetórias vinculadas ao campo científico, dos direitos humanos, dos direitos sexuais, do feminismo e do espaço AIDS, com alto capital burocrático e militante, que propiciou aproximação às questões relacionadas a saúde LGBT local. As condições de possibilidade que permitiram a formulação de propostas políticas baseadas na integralidade e na universalidade da atenção à saúde foram a formalização do Comitê Técnico Estadual de Saúde Integral LGBT da Bahia, em 2014, onde buscou-se ampliar a Atenção Integral à Saúde voltada às populações de maior vulnerabilidade; e o Plano Bahia sem homofobia, que permitiu ampliar o diálogo com a sociedade civil e os movimentos sociais e abarcar as principais críticas para a formulação de propostas políticas.

ABSTRACT OBJECTIVE To evaluate the evolution of the dietary patterns of adolescents in the northeast region of Brazil. METHODS Secondary analysis of data from the Pesquisa de Orçamentos Familiares (POF – Household Budget Surveys), collected by the Brazilian Institute of Geography and Statistics (IBGE) in the years 2008–2009 and 2017–2018. A total of 3,095 adolescents were evaluated in 2008–2009 and 3,015 in 2017–2018. Food consumption was assessed using two dietary records in 2008–2009 and two 24-hour recalls in 2017–2018, applied on non-consecutive days. Based on these data, principal components factor analysis (PCFA) was performed, followed by orthogonal rotation of the varimax type, to derive dietary patterns, stratified by sex. The results were described as means or percentage frequencies, with their respective 95% confidence intervals. RESULTS Three main dietary patterns were identified among adolescents from the northeast region of Brazil. Among boys, in 2008–2009, the patterns were called snacks, traditional Brazilian, and coffee; and in 2017–2018, traditional Brazilian, snacks, and mixed, in this order of representativeness of the group’s eating habits. Among female adolescents, in 2008–2009, the patterns were snacks, traditional Brazilian, and coffee; and in 2017–2018, traditional Brazilian, snacks, and processed meats. CONCLUSION The dietary patterns identified in 2008–2009 and 2017–2018 were similar in both genders; however, the snacks pattern, which explained most of the data variability in 2008–2009, was replaced by the traditional Brazilian.

ABSTRACT Objective. To provide a comprehensive overview of geographical patterns (2001–2010) and time trends (1993–2012) of cancer incidence in children aged 0–19 years in Latin America and the Caribbean (LAC) and interpret the findings in the context of global patterns. Methods. Geographical variations in 2001–2010 and incidence trends over 1993–2012 in the population of LAC younger than 20 years were described using the database of the third volume of the International Incidence of Childhood Cancer study containing comparable data. Age-specific incidence per million person-years (ASR) was calculated for population subgroups and age-standardized (WSR) using the world standard population. Results. Overall, 36 744 unique cases were included in this study. In 2001–2010 the overall WSR in age 0–14 years was 132.6. The most frequent were leukemia (WSR 48.7), central nervous system neoplasms (WSR 23.0), and lymphoma (WSR 16.6). The overall ASR in age group 15–19 years was 152.3 with lymphoma ranking first (ASR 30.2). Incidence was higher in males than in females, and higher in South America than in Central America and the Caribbean. Compared with global data LAC incidence was lower overall, except for leukemia and lymphoma at age 0–14 years and the other and unspecified tumors at any age. Overall incidence at age 0–19 years increased by 1.0% per year (95% CI [0.6, 1.3]) over 1993–2012. The included registries covered 16% of population aged 0–14 years and 10% of population aged 15–19 years. Conclusions. The observed patterns provide a baseline to assess the status and evolution of childhood cancer occurrence in the region. Extended and sustained support of cancer registration is required to improve representativeness and timeliness of data for childhood cancer control in LAC.

RESUMO Objetivo. Apresentar uma visão abrangente dos padrões geográficos (2001 a 2010) e das tendências temporais (1993 a 2012) da incidência de câncer em crianças e jovens de 0 a 19 anos na América Latina e no Caribe (ALC) e interpretar os resultados no contexto de padrões mundiais. Métodos. Foram descritas variações geográficas de 2001 a 2010 e tendências de incidência de 1993 a 2012 na população com menos de 20 anos da ALC usando informações comparáveis da base de dados do terceiro volume do estudo International Incidence of Childhood Cancer. Foram calculadas taxas de incidência específica por idade por milhão de pessoas-ano (ASR, na sigla em inglês) para subgrupos populacionais e taxas padronizadas por idade usando a população padrão mundial (WSR, na sigla em inglês). Resultados. No total, foram incluídos 36 744 casos únicos. No período de 2001 a 2010, a WSR para todos os tumores combinados na faixa etária de 0 a 14 anos foi de 132,6. Os diagnósticos mais frequentes foram leucemia (WSR de 48,7), neoplasias do sistema nervoso central (WSR de 23,0) e linfoma (WSR de 16,6). A ASR para todos os tumores combinados na faixa etária de 15 a 19 anos foi de 152,3, e a maior taxa foi a de linfoma (ASR de 30,2). A incidência foi maior no sexo masculino do que no sexo feminino e maior na América do Sul do que na América Central e no Caribe. De modo geral, em comparação com as estimativas mundiais, a incidência na ALC foi menor, exceto para leucemia e linfoma entre 0 e 14 anos e para outros tumores e tumores não especificados em qualquer idade. A taxa de incidência na faixa etária de 0 a 19 anos aumentou em 1,0% ao ano (IC de 95% [0,6, 1,3]) entre 1993 e 2012. Os registros incluídos cobriam 16% da população de 0 a 14 anos e 10% da população de 15 a 19 anos. Conclusões. Os padrões observados servem de referência para avaliar o status e a evolução da ocorrência de câncer infantil na região. É necessário garantir um apoio ampliado e consistente aos registros de câncer para aprimorar a representatividade e a disponibilidade das informações em tempo adequado para o controle do câncer infantil na ALC.
