Percepção de aprendizagem on-line na disciplina de biomateriais / Perception of online learning in the biomaterials course

Com as universidades fechadas e a implementação do Ensino Remoto Emergencial, as atividades curriculares ocorreram através de plataformas digitais. O objetivo do presente trabalho foi avaliar a percepção de aprendizagem on-line na disciplina de Biomateriais da Faculdade de Odontologia da Universidade Federal Fluminense no período da pandemia. O questionário COLLES (Constructivist OnLine Learning Environment Survey) foi enviado individualmente por e-mail aos cinquenta alunos, apresentando 24 declarações divididas em seis quesitos: relevância, reflexão crítica, interatividade, apoio dos tutores, apoio entre os colegas e compreensão; e para cada declaração cinco opções de resposta: quase sempre, frequentemente, algumas vezes, raramente e quase nunca. Quarenta e um alunos responderam. A soma das médias obtidas em quase sempre e frequentemente foi de 87,2% para relevância, 70% para reflexão crítica, 33,9% para interatividade, 47,6% para apoio dos tutores, 44,2% para apoio dos colegas e 89,5% para compreensão. Concluiu-se que a relevância, a reflexão crítica e a compreensão apresentaram melhores resultados, enquanto a interatividade, o apoio entre os colegas e o apoio dos tutores demonstraram necessidade de aprimoramento. E apesar das limitações do ERE, a avaliação positiva dos alunos evidenciou esta modalidade de educação on-line como uma solução plausível.

With universities closed and the implementation of Emergency Remote Teaching, curricular activities took place through digital platforms. The objective of this study was to assess the perception of online learning in the Biomaterials course at the Dental School of the Federal Fluminense University during the pandemic. The COLLES questionnaire (Constructivist OnLine Learning Environment Survey) was individually sent via email to fifty students, presenting 24 statements divided into six aspects: relevance, critical reflection, interactivity, tutor support, peer support, and comprehension. For each statement, there were five response options: almost always, often, sometimes, rarely, and almost never. Forty-one students responded. The sum of the averages obtained for almost always and often was 87.2% for relevance, 70% for critical reflection, 33.9% for interactivity, 47.6% for tutor support, 44.2% for peer support, and 89.5% for comprehension. It was concluded that relevance, critical reflection, and comprehension showed better results, while interactivity, peer support, and tutor support demonstrated a need for improvement. Despite the limitations of Emergency Remote Teaching, the positive evaluation from the students highlighted this mode of online education as a plausible solution.

Estudo longitudinal de famílias / Longitudinal study of families / Estudio longitudinal de familias

Introdução: O desenvolvimento da família é influenciado por diversos fatores de sua organização interna e de ordem ambiental, social, cultural, econômica e política. Em contexto de pobreza os riscos são maiores. Fatores de proteção, como boa organização familiar e rede social de apoio podem diminuir as consequências negativas da pobreza. São escassas as pesquisas longitudinais sobre vulnerabilidade e resiliência nas famílias. Objetivo: Este artigo descreve o desenvolvimento de três famílias ao longo de 15 anos, estudadas por meio de entrevistas em casa, parte de uma coorte populacional de um bairro de Porto Alegre (RS). Buscaram-se associações entre a qualidade das relações nessas famílias e sua saúde física e mental, especialmente a do filho, foco da pesquisa. Métodos: Selecionaram-se no arquivo da pesquisa as três primeiras famílias (do total de 148) das quais se tinham os resultados completos das cinco visitas realizadas aos quatro meses e aos dois, quatro, nove e 15 anos de um filho. Realizou-se análise qualitativa dos registros em busca de categorias para compreender a vida e as relações interpessoais nas famílias. O estudo foi realizado em conjunto por duas pesquisadoras, médicas especialistas em desenvolvimento humano. As categorias identificadas na análise e estudadas nas cinco etapas foram: configuração familiar, situação socioeconômica, situações traumáticas, saúde física, saúde relacional e mental, evolução cognitiva e escolar do filho. Resultados: As três famílias, todas de classe C, com filhos sem problemas de saúde física, tiveram evolução suficientemente boa, apesar de todas enfrentarem múltiplos problemas, inclusive separações e mortes precoces. A relação com o sistema de saúde e escola era boa e similar para as três. A jovem com menos problemas de saúde mental foi aquela que sofreu perdas mais importantes: morte dos pais. Tinha uma estrutura familiar multigeracional sólida desde a primeira infância, com relações interpessoais predominantemente colaborativas e amorosas. Conclusões: O artigo busca avançar na compreensão da resiliência nas famílias em situações de vulnerabilidade. Concluímos que essas três famílias, uma delas mais que as outras, foram suficientemente saudáveis na tarefa de educar seus filhos sem desenvolverem problemas mentais graves. Propomos que o bom desenvolvimento se associa com a adequação e amorosidade dos cuidados com a etapa do ciclo vital, mesmo enfrentando situações problemáticas. Essas qualidades precisam estar associadas à estabilidade socioeconômica básica e a bons serviços de saúde e escola.

Introduction: Family development is influenced by it's internal organization and environmental factors, socioeconomic, cultural and political. In poor contexts there are more risks to development. Protection factors like good family organization and social network may decrease the risks. Longitudinal research about vulnerability and resilience in families is scarse. Objective: This article describes the development of three families over 15 years through interviews at home. The families were part of a populational cohort of a neighborhood in Porto Alegre (RS). We looked for links between the quality of relationships and the physical and mental health of these families, especially of the child focus of the research. Methods: We selected in the research archives the first three families (of a total of 148) for which we had full results of the five interviews at four months and two, four, nine and fifteen years of a child. We did a qualitative analysis of the records looking for parameters to understand the life and interpersonal relationships of these families. This study was done by two researchers, both experts in Human Development. The categories identified in the analysis of the five phases were: family structure, socioeconomic situation, traumatic experiences, physical, mental and relational health and cognitive evolution of the child. Results: All three families belonged to economical class C. The children were in good physical health and had sufficiently good general development, having faced multiple problems, including parental separation and early parental death. The relationship with the health and school systems was good in all of them. The youth with less mental health problems was the one who suffered the heaviest loss: early death of both parents. Her family had strong multigenerational ties since her early days, with predominant collaborative and loving relationships. Conclusions: This article aims to contribute to the comprehension of resilience in families in the context of vulnerability. We can say that these three families were healthy enough in the task of bringing up children without any serious mental health problem. We suggest that healthy development is associated with loving interfamily relationships adequate to each phase of development, notwithstanding dramatic events. This needs to be supported by basic economic stability and adequate school and health systems.

Introducción: El desarrollo de la familia es influenciado por su organización interna y factores ambientales, sociales, culturales, económicos y políticos. En contextos pobres los riesgos son mayores. Factores de protección como buena organización familiar y red social de apoyo pueden disminuir las consecuencias negativas de la pobreza. Son pocas las investigaciones longitudinales de vulnerabilidad y resiliencia de las familias. Objetivo: Este artículo describe el estudio del desarrollo de tres familias a lo largo de 15 años, a través de entrevistas en domicilio, parte de una cohorte poblacional de un barrio de Porto Alegre (RS). Se buscaron correlaciones entre la calidad de las relaciones de esas familias y su salud física y mental, especialmente la del hijo foco de la investigación. Métodos: Fueron seleccionadas en el archivo de la investigación las tres primeras familias (de un total de 148) de las cuales se tenían los resultados completos de las cinco visitas realizadas, a los 4 meses, y a los 2, 4, 9, y 15 años de un hijo. Fue realizado un análisis cualitativo de los registros en busca de categorías para comprender la vida y las relaciones interpersonales en las familias. El estudio fue hecho en conjunto por dos investigadoras, médicas especialistas en desarrollo humano. Las categorías identificadas en el análisis y estudiadas en las cinco etapas fueron: configuración familiar, situación socioeconómica, situaciones traumáticas, salud física, salud relacional y mental, evolución cognitiva y escolar del hijo. Resultados: Las tres familias, todas de clase C, con hijos sin problemas de salud física, tuvieron evolución suficientemente buena, a pesar de que todas enfrentaron múltiples problemas, incluso separaciones y muertes precoces. La relación con el sistema de salud y escuela era buena y similar para las tres. La joven con menos problemas de salud mental fue aquella que sufrió las mayores pérdidas: muerte de los padres. Tenía una estructura familiar multigeneracional sólida desde la primera infancia, con relaciones interpersonales predominantemente colaborativas y amorosas. Conclusiones: El artículo pretende avanzar en la comprensión de la resiliencia en las familias en situaciones de vulnerabilidad. Concluimos que esas tres familias, una de ellas más que las otras, fueron suficientemente saludables en la tarea de educar a sus hijos sin que desarrollaran problemas mentales graves. Proponemos que el buen desarrollo se asocia con el amor y adecuación de los cuidados a la etapa del ciclo vital, aun enfrentando situaciones problemáticas. Esas calidades necesitan estar asociadas a la estabilidad socioeconómica básica y buenos servicios de salud y escuela.

Grupo de mulheres: o desenvolvimento de habilidades de facilitação e a geração de uma dinâmica de grupo promotora de saúde / Women's support group: the development of facilitation skills and the generation of a health-promoting group dynamic / Grupo de mujeres: el desarrollo de habilidades de facilitación y la generación de una dinámica grupal promotora de salud

Introdução: A realização de grupos é uma das possibilidades de atuação das equipes da Atenção Primária à Saúde. Esse tipo de intervenção possibilita o desenvolvimento de ações de cuidado que extrapolam as consultas individuais, propiciando educação em saúde, integração, troca de experiências e ampliação da rede de apoio. Ainda que não tenham necessariamente o propósito de serem terapêuticos em termos de saúde mental, apresentam-se como espaços de promoção de saúde e prevenção de agravos. O trabalho com grupos é capaz de gerar aprimoramento para todas as pessoas envolvidas ­ usuários e profissionais ­ na medida em que possibilita colocar em evidência os saberes da comunidade, abrindo a possibilidade de que as intervenções em saúde sejam criadas em coletivo. Objetivo: Analisar o processo de desenvolvimento da habilidade de facilitação de grupos e os impactos das habilidades adquiridas na sua dinâmica, bem como na sua efetividade como ferramenta de produção de saúde, considerando as habilidades e competências da Medicina de Família e Comunidade. Métodos: Trata-se de pesquisa qualitativa desenvolvida na UBS Santa Cecília. Os encontros aconteceram semanalmente pelo período de uma hora durante seis meses. A ferramenta utilizada para acompanhamento do desenvolvimento da habilidade de facilitação se deu pela observação estruturada, baseada em cinco competências básicas para facilitação de grupos. A dinâmica estabelecida consistiu na determinação de uma profissional facilitadora e outra observadora, que registrou as intervenções realizadas, sendo esses papéis invertidos a cada encontro. Quinzenalmente os dados eram analisados, gerando reflexões e sugestões para melhoria das intervenções. Resultados: Cada competência descrita na ferramenta utilizada teve como resultado o desenvolvimento de habilidades primordiais para o funcionamento do grupo. Um dos maiores indicadores do êxito em alcançar as habilidades desejadas ocorreu pela observação de intervenções cada vez menos necessárias, tomando as participantes os papéis de protagonistas e responsáveis pelo desenvolvimento do grupo, questionando, produzindo e obtendo saúde. Conclusões: A utilização de um instrumento de observação e reflexão das competências do agente atuante como facilitador de um grupo permitiu que a dinâmica se estabelecesse de forma fluida com rápido entendimento das participantes sobre seus papéis no contexto geral do grupo. Observou-se também que a relação estabelecida entre elas resultou na formação de rede de apoio, melhoria do autocuidado e conhecimento, informação em saúde e apoio social às envolvidas.

Introduction: Running support groups is one of the actions of Primary Health Care teams. This type of intervention enables the development of actions that go beyond individual consultations as the only space of care, providing health education, integration, exchange of experiences, and an enlargement in the support network. Although these groups do not necessarily have the purpose of being therapeutic in terms of mental health, they are presented as spaces for building health promotion and disease prevention. The alternative of groups as care practice generates improvement for all involved individuals ­ users and professionals ­ as it makes it possible to highlight the community's knowledge, opening the possibility that health interventions are created collectively. Objective: To analyze the process of ability development in regards to the facilitation of support groups and the impacts of the acquired skills on its dynamics, as well as on its effectiveness as a health production tool, considering the skills and competencies in Family and Community Medicine. Methods: Qualitative study developed at Santa Cecilia BHU. The meetings took place for one hour weekly over a six months period and the tool used to monitor the development of the facilitation skill was the instrument "Structured Observation", based on five basic skills for facilitating groups. The dynamics consisted of the determination of a professional facilitator and an observer, who recorded the interventions that were carried out, with these roles being reversed at each meeting. The data were analyzed bi-weekly, with reflections and suggestions for improving interventions. Results: Each competence described in the tool resulted in the development of essential skills for the functioning of the group. One of the major indicators of the achievement of the desired skills occurred by observing interventions that were less and less necessary, with participants taking on the roles of protagonists and becoming responsible for the development of the group, questioning, producing, and acquiring health. Conclusions: The use of an instrument for observing and reflecting on the skills of the agent acting as a group facilitator allows the dynamics to be fluidly established, with a quick understanding of the participants about their roles in the general context of the group. It was also observed that the relationship established between them resulted in the formation of a support network, improvement of self-care and knowledge, health information and social support for those involved.

Objetivo: Analizar el proceso de desarrollo de la habilidad de facilitación de grupos y los impactos de las habilidades adquiridas en la dinámica de este, así como en la efectividad como herramienta de producción de salud, considerando las habilidades y competencias de la Medicina de Familia y Comunidad. Métodos: Se trata de estudio cualitativo llevado a cabo en la UBS Santa Cecília. Los encuentros ocurrieron semanalmente durante una hora por seis meses y la herramienta utilizada para seguimiento del desarrollo de la habilidad de facilitación fue el instrumento Observación Estructurada, basado en cinco competencias básicas para facilitación de grupos. La dinámica establecida consistió en la determinación de una profesional facilitadora y otra observadora, que registró las intervenciones realizadas, siendo esos papeles cambiados a cada encuentro. A cada quince días los datos eran analizados, haciendo reflexiones y sugestiones para mejorar las intervenciones. Resultados: Cada competencia descrita en la herramienta utilizada tuvo como resultado el desarrollo de habilidades primordiales para el funcionamiento del grupo. Uno de los grandes indicadores del éxito en alcanzar las habilidades deseadas ocurrió por la observación de intervenciones cada vez menos necesarias, tomando las participantes los papeles de protagonistas y responsables por el desarrollo del grupo, cuestionando, produciendo y obteniendo salud. Conclusiones: La utilización de un instrumento de observación y reflexión de las competencias del agente actuante como facilitador de un grupo permiten que la dinámica se establezca de forma fluida con rápido entendimiento de las participantes sobre sus papeles en el contexto general del grupo. Se pudo observar también que la relación establecida entre ellas resultó en la formación de red de apoyo, mejora del autocuidado y conocimiento, información en salud y apoyo social a las involucradas.

Representation and practices of Electronic Nicotine Delivery System consumption in the university population of Bogotá(Colombia) / Representación social y prácticas de consumo de sistemas electrónicos de administración de nicotina en población universitaria de bogotá (colombia)

RESUMEN Objetivo: Colombia cuenta con una legislación de control del tabaco desde 2009 sin embargo, no existe una regulación específica sobre los Sistemas Electrónicos de Administración de Nicotina (SEAN), por lo tanto, es vital caracterizar las dimensiones cualitativas de consumo. El objetivo de este estudio fue identificar las prácticas y representaciones de los consumidores de SEAN con el fin de obtener elementos para orientar las acciones necesarias para prevenir su consumo. Materiales y métodos: Este artículo presenta los resultados identificados en el componente cualitativo de una investigación macro sobre la prevalencia del uso de SEAN entre estudiantes universitarios. Se realizaron 14 entrevistas individuales y 1 grupo focal, analizados con el software NVivo10®. Resultados: Se presentan como resultados principales la identificación de las prácticas de consumo, de las cuales se derivó que el núcleo central de la representación social sobre SEAN es no autónomo, lo que posibilita un cambio que desincentive su consumo; el sistema periférico de la representación está conformado por tres elementos: la dimensión social, el consumo de SEAN como estilo de vida y la dimensión corporal y emocional. Conclusiones: Se concluye que las acciones de prevención de consumo de SEAN deben partir de la identificación de características particulares y exclusivas del consumo de SEAN y la incorporación de los elementos del sistema periférico que permitan abordar un consumo que no se basa en la toma de decisiones informadas.

ABSTRACT Objective: Colombia has had a tobacco control legislation since 2009, however there is no specific regulation on Electronic Nicotine Delivery Systems (ENDS). Therefore, it is crucial to characterize the qualitative dimensions of consumption. The study aimed to answer the question: What are the representations and practices of the university population regarding the consumption of SEAN? The objective of the study is to identify the practices and representations of ENDS consumers in order to obtain elements to guide the necessary actions to prevent their consumption. Methods: This paper presents the results identified in the qualitative component of a main study on the prevalence of ENDS use among university students. 14 individual interviews and 1 focus group were conducted and analyzed with the NVivo10® software. The corpus consisted of the transcripts of the 14 interviews and 1 focus group, which constitutes a total of 116 pages of raw data. The techniques used were semi-structured interviews and focus groups, using the Microsoft Teams platform. Taking into account ethical aspects, in each interview and in the focus group the informed consent was read and authorization was requested for the interview to be recorded. The average duration of each interview was one hour and forty-five minutes and the focus group lasted a total of 120 minutes. The capture of practices and representation related to the use/non-use of SEAN was achieved by incorporating two phases of analysis: a)Inductivephase: it was developed with an ordered matrix on the theoretical categories of the project, b)Phase of deductive analysis was carried out based on processes typical of the founded theory that allowed expanding the analytical framework having as its axis the identification of consumption practices and the elements that make up the central core and the peripheral system of representation. Results: The main results are the identification of consumption practices, from which it was derived that the central nucleus of the social representation of SEAN is non-autonomous, which enables a change that discourages its consumption. The reasons and practices for consuming ENDS are closely related to conventional cigarette consumption, which corresponds to the fact that 11 of the 14 interviewees who identify themselves as consumers have consumed conventional cigarettes and only two have been exclusive ENDS consumers. The following practices were identified: a) The consumption motivations were grouped like social, economic and socio-emotional; b) Three types of consumption spaces: prohibited, exclusive and recovered spaces. These last ones are places where you couldn't smoke cigarettes and now they feel empowered to vape; c) There are forms of differential consumption and access to ENDS related to the quality, price, exclusivity and adherence; d) Habits and rituals are not related to moments of daily life, as with cigarettes, but to practices such as searching for and mixing "salts" to obtain flavors, cleaning and maintaining the device, smoking tricks; e) About information channels among the interviewees it was noted that the practice of informed consumption is not frequent and that there are few sources of information that offer low confidence. Finally, the peripheral system of representation is made up of three elements: social dimension, the consumption of SEAN as a lifestyle, bodied and emotional dimension. Conclusion : It is concluded that the actions to prevent the consumption of ENDS should start from the identification of particular and exclusive characteristics of the consumption of ENDS and the incorporation of the elements of the peripheral system that allow addressing a consumption not based on making informed decisions. The main finding is the identification of a non-autonomous representation that stems from the difficulty of establishing notable differentiations between conventional cigarette consumption and e-cigarettes. Therefore, the main vein of research that opens up is to delve into the particular and exclusive characteristics of this consumption. It is essential to incorporate bodily, emotional, and especially social (interpersonal) dimensions as important variables in understanding the practices and representations of e-cigarettes through complex approaches that can break the solid elements on which conventional cigarette consumption is anchored, as it continues to define dynamics of electronic device consumption. It is important at this point to recognize that emotions can be understood as the intermediary between the lived experience in the body and everything that happens in the environment. Thus, it is not possible to think of this representation without recognizing that consumption is an embodied exercise, and the absence of the body in discourses about e-cigarettes can be a revealing element of a disconnection between practices and meanings that are reinforced in the insistence on an action (smoking is smoking) despite the recognition of its negative effects on health (even though it should not be). The understanding of the social representation of e-cigarette consumption in relation to specific practices related to it provides some clues on which to work on processes of information, communication, prevention, and regulation to discourage this consumption that appears relatively new.

Uma reflexão sobre as conexões entrea fonoaudiologia e Saúde Única / A reflection on the connections betweenspeech therapy and One Health

A Saúde Única é uma crescente abordagem sistêmica para aumentar indissociavelmente os níveis de saúde das pessoas, dos animais e do ambiente no planeta. Por sua característica interdisciplinar e multidisciplinar, a Saúde Única tem arregimentado cada vez mais novos agentes na área de saúde, ampliando novas fronteiras de prática profissional. Objetivo: tendo em vista de que a abordagem sistêmica da Saúde Única (One Health) é holística, objetivou-se descrever e refletir sobre o papel da fonoaudiologia nesse contexto. Métodos: fez-se uma revisão de escopo sobre as ligações da fonoaudiologia com as desordens de saúde que são o foco em Saúde Única. Realizou-se uma procura de artigos nas plataformas PubMed e SciELO, com a combinação booleana dos indexadores "fonoaudiologia" e "Saúde Única", em idioma português; e as palavras "speech-language therapy" e "One Health" em idioma inglês. O operador booleano foi "E" e "AND". Adicionalmente, procurou-se teses e dissertações com esses mesmos operadores e combinações no Catálogo de Teses e Dissertações da CAPES. Analisou-se os dados por uma abordagem qualitativa, por isso os métodos estatísticos não foram aplicados. A partir dessa abordagem, complementou-se a argumentação com uma reflexão crítica sobre a inclusão da fonoaudiologia na estratégia de Saúde Única. Resultados: apenas na plataforma SciELO encontrou-se cinco obras com os descritores e a combinação "Saúde Única AND fonoaudiologia"; esse resultado é fortemente sugestivo de que o profissional em fonoaudiologia não tem sido incluído como um agente na abordagem Saúde Única. Contrariando esse cenário, argumenta--se que a fonoaudiologia pode preencher um nicho de trabalho e atuação acadêmica na abordagem de Saúde Única, cujo foco são desordens de saúde que podem resultar em distúrbios da comunicação nas pessoas. Considerações finais: há um nicho para a fonoaudiologia na abordagem da Saúde Única para a prevenção, o tratamento e a investigação científica das desordens da comunicação humana.

One Health is a growing systemic approach aimed at increasing the health levels of people, animals and the environment on the planet. Due to its inter- and multidisciplinary characteristics, One Health has been recruiting an increasing number of new agents in the health area, expanding new frontiers of professional practice. Objective: considering that the systemic approach of One Health is holistic, the objective is to describe and reflect on the role of speech therapy in this context. Methods: a scoping review was conducted to explore the connections between speech therapy and the health disorders that are the focus of One Health. A search for articles was carried out on the PubMed and SciELO platforms, using the Boolean combination of the terms "fonoaudiologia" (speech therapy) and "Saúde Única" (One Health), in Portuguese; and the words "speech-language therapy" and "One Health" in English using the Boolean operator "E" and "AND". Additionally, we searched for theses and dissertations with these same operators and combinations, in the CAPES Catalog of Theses and Dissertations. The data was analyzed using a qualitative approach, therefore statistical methods were not applied. Based on this approach, the argument was complemented with a critical reflection on the inclusion of speech therapy in the One Health strategy. Results: five works were found on the SciELO platform using the descriptors and combination "Saúde Única AND fonoaudiologia". This result suggests that the speech therapy professional has not been included as an agent in the One Health approach. Contrary to this scenario, it is argued that speech therapy can play a significant professional and academic role in One Health, which focuses on health disorders that may result in communication disorders. Final considerations: there is a niche for speech therapy in the One Health approach to the prevention, treatment and scientific investigation of human communication disorders.

Factors associated with non-pathogenic antibodies against desmoglein-3 in pemphigus foliaceus

Abstract Background Anti-desmoglein (Dsg)1 is produced in pemphigus foliaceus (PF), affecting exclusively the skin. Pemphigus vulgaris (PV) shows the production of anti-Dsg3 in the mucosal form, and anti-Dsg1 and 3 in the mucocutaneous form. Anti-Dsg3 autoantibodies have been rarely reported in PF. Objectives To determine the factors associated with the production and pathogenicity of anti-Dsg3 in PF. Methods Comparative analytical study of three patients groups: 16 PF-anti-Dsg3+, and 42 PF-anti-Dsg3(-) and 22 PV treatment-naïve cases. Serum was used in the anti-Dsg1 and 3 ELISA, and in immunoblotting (IB) with human epidermis extract. The expression of Dsg1 and 3 in paraffin sections was analyzed by immunohistochemistry (IHC). HLA-DRB1 alleles were compiled from a database. Results In the PF-anti-Dsg3+ group: age range similar to that of the PV group (p > 0.9999); predominance of the generalized form of PF (p = 0.002); anti-Dsg3 titers lower than those of PV (p < 0.0001); IB confirmed Dsg3 identification in one (8.33%) of 12 patients; IHC showed exclusive cytoplasmic internalization of Dsg1; HLA-DRB1 alleles of susceptibility to PF, with the absence of alleles associated with PV, in the five typed patients. Study limitations Most of the patients in the PF-anti-Dsg3+ group were undergoing treatment. Conclusion The presence of anti-Dsg3 antibodies in PF was related to older age (comparable to that of PV) and the generalized form of PF. The non-pathogenicity of anti-Dsg3 antibodies in PF can be attributed to the low serum anti-Dsg3 titers, the lack of Dsg3 internalization as detected by IHC, and the absence of PV-associated HLA-DRB1 alleles.

Instructional videos for parents/guardians of children with lip and palate clefts: integrative literature review

Abstract Objective This study aimed to review literature from the past five years, focusing on the use of educational videos as a guidance tool for parents and guardians of children with lip and palate clefts. Source of data Conducted between April and July 2022, this integrative literature review was framed around the question: 'What is the evidence regarding the use of videos in health education for parents/guardians of children with cleft lip and palate? PICO strategy was used to develop the research. A literature search was undertaken across PubMed, Web of Science, Scopus, and the Virtual Health Library databases. Of the eight articles included in this review, four were sourced from the PubMed database, with three published in 2021. Summary of the findings The findings indicated that YouTube videos were moderately satisfactory and met the needs of parents or legal guardians to a partial extent. The majority of the videos analyzed in this review were characterized by a moderate level of informational content. One study particularly underscored that the content of these videos only partially satisfies the requirements of the parents or legal guardians of the children. Conclusions Nevertheless, such videos are considered viable alternatives for health education, offering numerous benefits yet facing challenges, primarily due to the scarcity of information on orofacial malformations.

Recomendaciones ALAT para el uso de vacunas respiratorias. Guía de práctica clínica basada en evidencias / ALAT Recommendations for the Use of Respiratory VaccinesEvidence-Based Clinical Practice Guideline

Introducción: Las infecciones respiratorias son las enfermedades respiratorias con mayor mortalidad en el mundo. Las causadas por Streptococcus pneumoniae, virus de influenza, Bordetella pertussis, SARS-CoV-2 y el Virus Sincitial Respiratorio, cuentan hoy día con vacunas seguras y efectivas. Este documento representa una guía de práctica clínica (GPC) de la Asociación Latinoamericana de Tórax (ALAT), elaborada por iniciativa de los departamentos de enfermedades infecciosas y pediatría, con el objetivo de establecer recomendaciones sobre vacunas respiratorias, utilizando la evidencia disponible. Método: Se estableció un grupo de desarrollo de las guías conformado por cinco médicos responsables globales del proyecto, se crearon cinco subgrupos de trabajo, uno por cada vacuna, con expertos neumólogos de adulto, pediatras e infectólogos invitados, que generaron preguntas clínicas. Se trabajó con un grupo de expertos metodólogos que transformaron preguntas clínicas en preguntas PICO, seleccionándose nueve preguntas por método DELPHI. Luego, se utilizó el sistema GRADE (Grading of Recommendations Assessment, Development and Evaluation) para evaluar la evidencia disponible. Resultados: Se obtuvieron recomendaciones para población adulta y pediátrica de las vacunas de neumococo, influenza, tos ferina, COVID-19 y Virus Respiratorio Sincitial basadas en preguntas PICO. También se agregaron recomendaciones basadas en preguntas narrativas relacionadas al uso de vacunas respiratorias en población con enfermedades respiratorias crónicas como asma, EPOC y fibrosis pulmonar.

Introduction: Respiratory infections are the leading cause of respiratory disease-related mortality worldwide. Infections caused by Streptococcus pneumoniae, influenza virus, Bordetella pertussis, SARS-CoV-2 and Respiratory Syncytial Virus (RSV) now have safe and effective vaccines available.This document represents a Clinical Practice Guideline (CPG) by the Latin American Thoracic Association (ALAT), developed through the initiative of the departments of in-fectious diseases and pediatrics, with the goal of establishing recommendations on respiratory vaccines using the available evidence. Method: A guideline development group was established, composed of five lead physicians responsible for the overall project. Five working subgroups were created, one for each vaccine, involving invited experts in adult pulmonology, pediatrics, and infectious diseases, who formulated clinical questions. A group of expert methodologists then transformed these clinical questions into PICO questions, with nine questions selected using the DELPHI method. The GRADE (Grading of Recommendations Assessment, Development and Evaluation) system was then used to assess the available evidence. Results: Recommendations were obtained for the adult and pediatric populations for pneumococcal, influenza, pertussis, COVID-19 and Respiratory Syncytial Virus vaccines based on PICO questions. Additionally, recommendations based on narrative questions related to the use of respiratory vaccines in populations with chronic respiratory diseases such as asthma, COPD, and pulmonary fibrosis were included.

Assessment of efficacy and safety of clindamycin with nicotinamide in mild to moderate acne vulgaris: a prospective study

Background: Acne vulgaris is a very common skin disease that is usually treated with topical products, systemic medications, or a combination of both. Acne vulgaris affects approximately 9% of the population worldwide causing permanent physical scarring, negatively affects the quality of life and self-image, and has been associated with increased rates of anxiety, depression, and suicidal ideation. Methods: This was a prospective study conducted at BMCRI including thirty-five subjects who were diagnosed with mild to moderate acne vulgaris. Patients were treated with topical clindamycin 1% with nicotinamide 4%. Efficacy was assessed by mean change in acne severity index (ASI) and total lesion count (TLC) from baseline and at the end of 4, 8 and 12 weeks. Safety was assessed by adverse events reported. Results: There was statistically significant improvement noted at the end of each visit. Baseline ASI was 88.05±4.02 and end of 12 weeks was 14.17±2.7. Baseline TLC was 30.17±1.33 and at the end of 12 weeks was 4.25±0.99. Both the ASI and TLC results were statistically significant at the end of fourth, eighth and twelfth-week p value <0.0001. Conclusions: Combination topical formulations are the most broadly used treatment regimen for Acne vulgaris to target one or more steps in the pathogenesis of acne. From the results of the present study the participants on combination of clindamycin with nicotinamide had a significant improvement in acne lesions at end of 12th week of topical application and were satisfied with the therapy with no major adverse effects.

Trasplante hepático como tratamiento de intoxicación por paracetamol / Liver transplantation as treatment for acetaminophen poisoning

Resumen El paracetamol es una droga analgésica y antipiré tica comúnmente utilizada, que ha experimentado un aumento en su consumo en los últimos años en nuestro medio. También se ha observado un incremento en el número de sobredosis accidentales e intencionales que fueron atendidas por el sistema de salud. Su toxicidad es dosis dependiente y puede causar falla hepática fulminante, convirtiéndose en una de las principales razones de trasplante hepático en países angloparlan tes. Se presenta el caso de una mujer de 28 años con antecedentes de depresión mayor y cinco intentos de suicidio previos, quien ingirió deliberadamente una cantidad significativa de comprimidos de paracetamol. Desarrolló una falla hepática fulminante y acidosis metabólica, por lo que fue sometida a un trasplante hepático de emergencia debido a la gravedad de su condición evolucionando favorablemente. La decisión de realizar un trasplante hepático en casos graves como este y bajo una condición de vulnerabilidad psiquiátrica grave, es un desafío y debe considerarse cuidadosamente. Este caso en particular ilustra la im portancia de la atención multidisciplinaria incluyendo la evaluación psiquiátrica en pacientes con intoxicación por paracetamol.

Abstract Acetaminophen is a commonly used analgesic and antipyretic drug, which has experienced an increase in its consumption in recent years in our environment. There has also been an increase in the number of accidental and intentional overdoses that were treated by the health system. Its toxicity is dose-dependent and can cause ful minant liver failure, becoming one of the main reasons for liver transplantation in English-speaking countries. The case of a 28-year-old woman with a history of major depression and five previous suicide attempts, who de liberately ingested a significant amount of paracetamol tablets, is here presented. She developed fulminant liver failure and metabolic acidosis, for which she underwent an emergency liver transplant due to the severity of her condition, from which she evolved favorably. The decision to perform a liver transplant in serious cases like this and under a condition of severe psychiatric vulnerability is challenging and must be carefully considered. This particular case illustrates the importance of multidisci plinary care including psychiatric evaluation in patients with acetaminophen poisoning.

Registro argentino de MINOCA. Descripción de la población / Argentine MINOCA Registry. Description of the Population

RESUMEN Introducción: El infarto de miocardio sin obstrucciones coronarias significativas (MINOCA) es una conocida entidad que se ha redefinido recientemente al excluir la injuria miocárdica no isquémica. ReSCAR fue un registro prospectivo, multicéntrico de pacientes hospitalizados por síndrome coronario agudo (SCA) desde enero hasta agosto de 2022. Objetivo: Un objetivo principal del registro fue definir la prevalencia de pacientes con MINOCA, sus características basales clínicas y paraclínicas y evolución intrahospitalaria. Los resultados del análisis respectivo son la base de esta publicación. Material y métodos: Registro nacional prospectivo y multicéntrico de SCA. Diagnóstico de MINOCA de acuerdo con la Cuarta Definición Universal de Infarto de Miocardio. Análisis de las características basales, evolución y diferencias significativas respecto de los pacientes con coronariopatía obstructiva. Los centros participantes debían contar con determinación de troponina de alta sensibilidad y la posibilidad de realizar cinecoronariografía. Resultados: Se incluyeron 984 pacientes de 15 centros. Ochenta y cinco pacientes (8,6 %) tuvieron diagnóstico final de MINOCA al alta. Cuarenta y cuatro pacientes (51,8 %) eran mujeres, la mediana de edad fue de 65 años (53-63), 55 (64,7 %) pacientes eran hipertensos, 44 (51,8 %) dislipidémicos, 9 (10,6 %) diabéticos y 23 (27,1 %) fumadores. La mediana de troponina al ingreso (expresada como múltiplo del percentilo 99) fue de 2,42 (0,85-10,21) y el 71,8 % se presentó con un ECG sin cambios isquémicos. La angiografía coronaria fue normal en el 72,9 % de los pacientes y con lesiones menores de 50 % en el resto. Se realizó resonancia cardíaca a 16 pacientes. La mediana del score GRACE fue de 115 puntos (98-139), lo cual perfila un riesgo intermedio; con una tasa de eventos combinados de accidente cerebrovascular/infarto o muerte de 1,2 %, sin haberse registrado sangrados BARC 2 o más. La prescripción al alta de aspirina fue del 72,9 %, clopidogrel 27,1 %, estatinas 88,2 %, beta bloqueantes 67,1 % y antagonistas cálcicos 22,4 %. Conclusión: En este registro, los pacientes con MINOCA representan una proporción significativa de aquellos con SCA. La tasa de complicaciones intrahospitalarias, incluida la mortalidad, fue baja. Impresiona existir una fuerte oportunidad para profundizar los estudios para confirmar este diagnóstico, sus mecanismos fisiopatológicos y su tratamiento.

ABSTRACT Background: Myocardial infarction with non-obstructive coronary arteries (MINOCA) is a well-known condition that has been recently redefined after excluding non-ischemic myocardial injury. ReSCAR was a prospective, multicenter registry of patients hospitalized for acute coronary syndrome (ACS) from January to August 2022. Objective: One of the main objectives of the registry was to define the prevalence of patients with MINOCA, their baseline clinical and paraclinical characteristics, and in-hospital outcome. This publication focuses on the results of the respective analysis. Methods: We conducted a nationwide, multicenter, prospective study of patients with ACS. The diagnosis of MINOCA was made following the Fourth Universal Definition of Myocardial Infarction. The baseline characteristics of the patients wereanalyzed, as well as their outcome and significant differences with patients with obstructive coronary artery disease. The participating centers should have the availability to measure high-sensitivity cardiac troponin and perform coronary angiography. Results: A total of 984 patients from 15 centers were included. Eighty-five patients (8.6%) had a final diagnosis of MINOCA at discharge. Median age was 65 years (53-63), 48 (51.8%) were women, 55 (64.7%) had hypertension, 44 (51.8%) had dyslipidemia, 9 (10.6%) were diabetics and 23 (27.1%) were smokers. Median high-sensitivity cardiac troponins on admission (expressed as multiples of the 99th percentile) were 2.42 times higher (0.85-10.21) and the ECG had no ischemic changes in 71.8% of the patients. Coronary angiography was normal in 72.9% of the patients and the rest of the cases had coronary artery stenoses < 50%. Sixteen patients underwent cardiac magnetic resonance imaging. The median GRACE score was 115 (98-139), which corresponds to intermediate risk. The event rate for the composite outcome of stroke/myocardial infarction or death was1.2%, and there were no bleeding events BARC ≥type 2. The discharge prescription rate was 72.9% for aspirin, 27.1% for clopidogrel, 88.2% for statins, 67.1% for beta-blockers, and 22.4% for calcium channel blockers. In this registry, patients with MINOCA represent a significant proportion of those with ACS. Conclusion: The rate of in-hospital complications, including mortality, was low. There seems to be a strong opportunity for further investigations to confirm the diagnosis, pathophysiological mechanisms, and treatment of MINOCA.

Experiencia de trabajo de cuidados de trabajadores de la salud en Chile durante la pandemia COVID-19 y su impacto en la salud mental: estudio cualitativo a partir de la iniciativa internacional HEROES / The caregiving work experience of healthcare workers in Chile during the COVID-19 pandemic and its impact on mental health: A qualitative study based on the international initiative HEROES

Introducción La pandemia por COVID-19 ha impactado la salud mental de los trabajadores de salud. La perspectiva de cuidados se ha identificado como necesaria de estudiar, para entender causas atribuibles asociadas a hallazgos específicos en materia de salud mental y proponer cursos de acción para abordarla. Métodos Estudio de carácter transversal con enfoque analítico temático, derivado de la iniciativa internacional (HEROES) Fue realizado entre trabajadores de salud en Chile, durante el segundo semestre de 2022 y el primero de 2023, a través entrevistas semiestructuradas y codificación inductiva. Resultados Síntesis narrativa de 35 entrevistas, en cuatro temas: cuidados en el trabajo: presencia de cambios de funciones, preocupación por contagio, "mística" colectiva, estigma por condición de trabajador de la salud, conflictos con pacientes; cuidados en el hogar: diversas formas de arreglos de tareas domésticas, relevancia de la convivencia con otros, interrelación con dinámicas laborales, "doble carga" entre mujeres; relación con la propia salud mental: reconocimiento de afectación en salud mental, estrés asociado a cambio e incertidumbre, percepción de sobrecarga laboral, sentimientos de culpa o responsabilidad por contagio a familiares; y creencias y valores sobre la pandemia y sus efectos: aceptación de afectación psíquica de trabajadores de la salud, cultura organizacional como elemento relevante en postergación de propia salud mental, incredulidad inicial ante efectos de la pandemia, similitudes con periodos de conmoción social previos, igualdad entre personas respecto a vulnerabilidad frente a enfermedad. Conclusiones Cinco elementos surgen como potenciales áreas de intervención: perspectiva de género, exposición previa a experiencias de crisis, espacios de autocuidado, apoyo de pares y respuesta institucional. La perspectiva de cuidados es útil para estudiar la relación entre algunos factores estresantes y la salud mental de los trabajadores de salud en el contexto de pandemia.

Introduction The COVID-19 pandemic has impacted the mental health of healthcare workers. Studying the care perspective is essential to understanding the causes of specific mental health findings and proposing strategies to address them. Methods Cross-sectional study with a thematic analytical approach, derived from the international initiative "The Health Care Workers Study" (HEROES), conducted among healthcare workers in Chile during the second semester of 2022 and the first of 2023 through semi-structured interviews and inductive coding. Results A narrative synthesis of 35 interviews in four themes: care at work: the presence of changes in work tasks, concern about becoming infected, collective "mystique", stigma due to being a healthcare worker, conflicts with patients; care at home: multiple ways of arranging household tasks, the relevance of living with others, interrelation with work dynamics, "double burden" among women; relationship with one's own mental health: recognition of mental health impact, the stress associated with change and uncertainty, perception of work overload, feelings of guilt or responsibility for infecting family members; and beliefs and values about the pandemic and its effects: acceptance of psychological impact on healthcare workers, organizational culture as a relevant element in postponing one's own mental health, initial disbelief in the effects of the pandemic, similarities with previous periods of social upheaval, and equality among people in terms of vulnerability to the disease. Conclusions Five elements emerge as potential areas for intervention: gender perspective, previous exposure to crisis experiences, self-care spaces, peer support, and institutional response. The care perspective helps study the relationship between some stressors and healthcare workers' mental health in the context of a pandemic.

Perspectivas de estudantes e egressos sobre a aprendizagem baseada em problemas na formação de enfermeiros / Students' and graduates' perceptions on problem-based learning in nursing undergraduate education

Resumo Objetivou-se analisar a percepção de estudantes e egressos sobre a utilização da Aprendizagem Baseada em Problemas (ABP) na formação do enfermeiro. Trata-se de um estudo qualitativo que utiliza a modalidade compreensiva e interpretativa proposta pela Hermenêutica-Dialética. Realizaram-se quatro grupos focais com a participação de 17 estudantes e 16 egressos de uma instituição de ensino superior que aplica a ABP na formação de enfermeiros. A análise dos resultados permitiu a definição de cinco categorias temáticas: dificuldade de adaptação em relação ao método; conquista de autonomia sobre o próprio aprendizado; incentivo ao desenvolvimento do raciocínio clínico; aprimoramento da comunicação e das relações interpessoais e integração entre teoria e prática. Evidencia-se que a utilização da ABP favorece a aproximação com as proposições das diretrizes curriculares para a formação do enfermeiro por meio do desenvolvimento de habilidades e competências como autonomia, comunicação, relações interpessoais e raciocínio clínico mediante práticas integrais e contextualizadas. Entretanto, os estudantes enfrentam dificuldades com as mudanças observadas ao serem inseridos nela ABP, as quais são superadas no decorrer do processo de implementação.

Abstract This study aimed to analyze students' and graduates' perceptions regarding the use of Problem-Based Learning (PBL) in nurse education. This is a qualitative study that employs the comprehensive and interpretative approach proposed by Dialectical Hermeneutics. Four focus groups were conducted with the participation of 17 students and 16 graduates from a higher education institution that implements PBL in nurse education. The analysis of results allowed for the identification of five thematic categories: difficulty in adapting to the method; attainment of autonomy in one's own learning; encouragement of clinical reasoning development; enhancement of communication and interpersonal relationships; and integration between theory and practice. It is evident that the use of PBL promotes alignment with the propositions of curriculum guidelines for nurse education by fostering the development of skills and competencies such as autonomy, communication, interpersonal relationships, and clinical reasoning through comprehensive and contextualized practices. However, students encounter challenges with the changes observed when introduced to PBL, which are overcome during the implementation process.

Objetivo: Validar el contenido de un cuestionario de auto-reporte en español para explorar actitudes, prácticas y barreras de odontólogos no especialistas en periodoncia frente al diagnóstico y tratamiento de problemas periodontales y criterios para derivar. Materiales y métodos: Seis especialistas en periodoncia de cinco países latinoamericanos construyeron versión#1 de un cuestionario. 21 expertos de tres áreas disciplinares de 6 países valoraron de 1 a 5 (1: totalmente en desacuerdo, 5: totalmente de acuerdo) cada ítem en su pertinencia, relevancia, claridad y coherencia. Según grado de acuerdo se reformuló cada ítem y se construyó versión#2 que fue piloteada en 60 odontólogos no especialistas en periodoncia, 3 de ellos fueron entrevistados para evaluar la comprensión y semántica. Luego del análisis se elaboró la versión final (versión#3). Resultados: Los ítems formulados de versión#1 tuvieron una valoración promedio de 4,6 (rango 3.7-5). Fueron reformulados evitando palabras confusas y que tuvieran aceptación transversal en países participantes, se eliminó ítem con menor puntuación de acuerdo de expertos. La aplicación de versión#2 tuvo un tiempo de respuesta de 12 minutos, se reformularon opciones y agregaron 4 ítems para obtener la versión final con 44 preguntas. Conclusiones: Se construyó un cuestionario de auto-reporte con validez de contenido para evaluar actitudes y prácticas en salud-enfermedad periodontal en odontólogos generales o no especialistas en periodoncia de habla hispana.

Aim: T o validate the content of a self-report questionnaire in Spanish to explore attitudes, practices and barriers of dentists non-specialized in periodontics when facing the diagnosis and treatment of periodontal problems and criteria for referral. Materials and methods: Six specialists in periodontics from five Latin American countries constructed version#1 of a questionnaire. Twenty-one experts from 3 disciplinary areas from 6 countries rated each item from 1 to 5 (1: totally disagree, 5: totally agree) regarding its appropriateness, relevance, clarity, and coherence. According to the degree of agreement, the item was reformulated, and version #2 was built, which was tested on 60 dentists non-specialized in periodontics. Then, 3 of them were interviewed to assess comprehension and semantics. After analysis, the final version was prepared (version#3). Results: The items formulated in version#1 had an average score of 4.6 (range 3.7-5). Questions and options were reformulated, avoiding confusing words and having transversal acceptance in the participating countries. The items with the lowest degree of expert agreement were eliminated. The application of version#2 had a response time of 12 minutes, options were reformulated, and 4 items were added to obtain the final version with 44 questions. Conclusions: A self-report questionnaire with content validity was constructed to assess attitudes and practices in periodontal health and disease in Spanish-speaking general dentists or non-specialists in periodontics.

Assessing the Elastic Components of the Aortic Media in Goats (Capra hircus) / Evaluación de los Componentes Elásticos de la Aorta en Cabras (Capra hircus)

SUMMARY: Samples were collected from five goats (Capra hircus) from the ascending aorta, aortic arch, descending thoracic aorta, and descending abdominal aorta. These samples were histologically processed to reveal elastic structures in their media. The mean number of elastic lamellae discovered was 91.5 in the mean ascending aorta, 78.5 in the mean aortic arch, 66 in the mean descending thoracic aorta, and 31.7 in the mean descending abdominal aorta. Because they all have a large number of elastic laminae on average, they all fall into the elastic artery category, but not all are typical elastic arteries. Thus, the ascending aorta, the aortic arch, and the descending thoracic aorta contain, on average, in addition to elastic tissue, polymorphous muscle islands, which distinguishes them from typical elastic arteries, which is why we call them particular elastic arteries. The descending abdominal aorta contains no such islands so that it can be classified as a typical elastic artery. The goat aortic segment is the only one comparable in structure to the elastic arteries of humans, which is why we suggest that it is the only one suitable for studying aortic disease in humans.

Se recogieron muestras de cinco cabras (Capra hircus) de la aorta ascendente, el arco aórtico, la aorta torácica descendente y la aorta abdominal descendente. Estas muestras se procesaron histológicamente para revelar estructuras elásticas en sus capas. El número medio de laminillas elásticas descubiertas fue de 91,5 en la aorta ascendente, 78,5 en el arco aórtico, 66 en la aorta torácica descendente y 31,7 en la aorta abdominal descendente. Debido a que todas tienen en promedio una gran cantidad de láminas elásticas, caen en la categoría de arterias elásticas, pero no todas son arterias elásticas típicas. Así, la aorta ascendente, el arco aórtico y la aorta torácica descendente contienen, en promedio, además de tejido elástico, islas de músculos polimorfos, lo que las distingue de las arterias elásticas típicas, por lo que las llamamos arterias elásticas particulares. La aorta abdominal descendente no contiene tales islas, por lo que puede clasificarse como una arteria elástica típica. El segmento aórtico de cabra es el único comparable en estructura a las arterias elásticas de los humanos, por lo que sugerimos que es el único adecuado para estudiar la enfermedad aórtica en humanos.

Incorporación de Tecnología Tridimensional mediante Tomografía Microcomputarizada en el Estudio de la Anatomía de Salmónidos: Una Evaluación de Utilidad / Integration of Three-Dimensional Technology through Microcomputed Tomography in the Study of Salmonid Anatomy: A Utility Evaluation

Los salmónidos, durante su desarrollo, pueden experimentar ocasionalmente deformaciones esqueléticas. Para su diagnóstico se emplean diversas metodologías, entre las que se incluyen radiografías, técnicas histológicas, diafanización con tinciones de alizarina y azul de alcián, así como el uso del microscopio electrónico de barrido (SEM), cada una con sus inherentes ventajas y desventajas. Este estudio tuvo como finalidad evaluar y comparar la eficacia de la tomografía microcomputarizada (Micro-CT) para el análisis anatómico, reconstruyendo tridimensionalmente las imágenes y contrastándolas con los resultados obtenidos mediante la técnica de diafanización. Se analizaron las aletas caudales de cinco ejemplares de salmón Oncorhynchus kisutch: dos sujetos a diafanización y tres procesados para análisis mediante Micro-CT utilizando el equipo BRUKER SkyScan 1272. La técnica de Micro-CT demostró superioridad en la resolución de las estructuras óseas, facilitando una exploración detallada de las variaciones morfológicas y la distribución de la densidad mineral. Este enfoque permitió identificar anomalías en la morfología y crecimiento de las últimas vértebras y lepidotriquias dorsales, así como una densidad incrementada en lepidotriquias dorsales malformadas. La mayor resolución proporcionada por la Micro-CT no solo potencia nuestra comprensión de la ontogenia piscícola y su adaptación a ambientes diversos, sino que además inaugura perspectivas innovadoras para el estudio de la evolución de las estrategias locomotoras y las respuestas adaptativas frente a cambios ambientales a través del tiempo.

SUMMARY: During their development, some species of salmonids may occasionally experience skeletal deformations. Several methodologies are currently being used for the diagnosis of such malformations, among which X-rays, histological techniques, diaphanization coupled either with Alizarin Red or Alcian Blue stains, as well as Scanning Electron Microscopy (SEM) can be mentioned. Each one of those methods presents inherent advantages and disadvantages. The purpose of this study was twofold: Firstly, to evaluate and compare the effectiveness of microcomputed tomography (Micro-CT) technology for anatomical analysis, three-dimensionally reconstructing the obtained images; and secondly, to contrast those images with the results obtained through the diaphanization technique. The caudal fins of five specimens of the Oncorhynchus kisutch salmon were analyzed: Two specimens were subjected to diaphanization and three were processed for Micro-CT analysis, using the BRUKER SkyScan 1272 equipment. The Micro-CT technology demonstrated superiority in the resolution of bone structures, facilitating a detailed exploration of morphological variations, as well as the distribution of mineral density. This experimental approach allowed us to identify anomalies in the morphology and growth of the last vertebrae and dorsal lepidotrichiae, as well as an increased mineral density in the malformed dorsal lepidotrichiae. The higher resolution provided by Micro-CT not only enhances our understanding of the fish ontogeny and its adaptation to diverse environments, but also opens innovative perspectives for the study of the evolution of locomotor strategies and adaptive responses to environmental changes.

Age-dependent Model for Dynamics of Change in Body Composition Indicators in Professional Firefighters: Serbian Cross-Sectional Study / Modelo Dependiente de la Edad para la Dinámica de Cambio en los Indicadores de Composición Corporal en Bomberos Profesionales: Estudio Transversal Serbio

SUMMARY: The aim of this study was to establish an age-related dynamic of change model for predicting changes in body composition indicators in professional firefighters. The study included a total sample of 145 subjects, comprising professional firefighters from Serbia (Age: 36.6 ± 7.6 yrs., Min - Max: 21.0 - 52.0 yrs.). Four basic variables were analysed: Body Mass - BM, Body Fat Mass - BFM, Skeletal Muscle Mass - SMM, and Visceral Fat Area - VFA, as well as five derived, or index, variables: Body Mass Index - BMI, Percentage of Body Fat - PBF, Percentage of Skeletal Muscle Mass - PSMM, Protein-Fat Index - PFI, and Index of Body - IBC Composition. The results showed a statistically significant dynamic of change as a function of age for eight of the examined variables, while only one (Skeletal Muscle Mass - SMM) was not statistically significant. The highest statistical significance in terms of dynamics of change as a function of age was found for the variable VFA (F = 35.241, p = 000) and the variable PSMM (F = 31.398, p = 0.000). Professional firefighters in Serbia fall into the category of people with normal nutritional indicators. However, due to a dominant increase in visceral fat (VFA) combined with a dominant decrease in the proportion of skeletal muscles in the body (PSMM), it can be concluded that they are exposed to a risk of developing various chronic diseases, while their working conditions, which promote certain negative lifestyle habits, also contribute to the observed increase in body fat components.

El objetivo de este estudio fue establecer un modelo de dinámica de cambio relacionada con la edad para predecir cambios en los indicadores de composición corporal en bomberos profesionales. El estudio incluyó una muestra total de 145 sujetos, incluidos bomberos profesionales de Serbia (Edad: 36,6 ± 7,6 años, mín. - máx.: 21,0 - 52,0 años). Se analizaron cuatro variables básicas: Masa Corporal - MC, Masa Grasa Corporal - MGC, - Masa Muscular Esquelética - MME y Área Grasa Visceral - AGV, así como cinco variables derivadas o indexadas: Índice de Masa Corporal - IMC, Porcentaje de grasa corporal - PGC, porcentaje de masa muscular esquelética - PMME, índice proteína-grasa - IPG e índice de composición corporal - ICC. Los resultados mostraron una dinámica de cambio estadísticamente significativa en función de la edad para ocho de las variables examinadas, mientras que sólo una, MME no fue estadísticamente significativa. La mayor significancia estadística en términos de dinámica de cambio en función de la edad se encontró para la variable AGV (F = 35,241, p = 000) y la variable PMME (F = 31,398, p = 0,000). Los bomberos profesionales de Serbia pertenecen a la categoría de personas con indicadores nutricionales normales. Sin embargo, debido a un aumento dominante de la grasa visceral combinado con una disminución dominante de la PMME, se puede concluir que están expuestos a un riesgo de desarrollar diversas enfermedades crónicas, mientras que las condiciones de trabajo, que promueven ciertos hábitos de vida negativos, también contribuyen al aumento observado de los componentes de la grasa corporal.

Efficacy and safety of 0.5% colchicine cream versus 5% 5-fluorouracil cream in the treatment of cutaneous field cancerization: a randomized clinical trial

Abstract Background 5-Fluorouracil (5-FU) is a first-line drug to treat cutaneous field cancerization (CFC). There are few clinical trials with topical colchicine (COL). Objective To evaluate the effectiveness of 0.5% COL cream versus 5% 5-FU cream in the treatment of CFC. Method This was a randomized, open, self-controlled clinical trial. Forty-five patients (90 forearms), with three to ten actinic keratoses (AK) on each forearm, used 0.5% COL cream 2×/day for seven days on one forearm, and 5% 5-FU cream 2× /day, for 21 days, on the other forearm. The dosages were defined based on previous clinical trials for each drug. Adverse effects were evaluated after 14 days and outcomes after 90 days of inclusion. The primary outcome was complete AK clearance and the secondary outcomes were: partial clearance (≥50%), reduction in AK count, assessment of the Forearm Photoaging Scale (FPS), AK Severity Score (AKSS), and adverse effects. Results After 90 days, there was complete clearance of AK in 37% (95% CI 24%-49%) and partial clearance in 85% (95% CI 76%-93%) of the forearms treated with 5-FU,versus 17% (95% CI 7%-27%) and 78% (95% CI 66%-88%) for COL (p > 0.07). There was a percentage reduction of 75% in the AK count of the forearms treated with 5-FU (95% CI 66%-83%) and 64% in those treated with COL (95% CI 55%-72%). Regarding FPS and AKSS, there was improvement in both groups, with no difference regarding FPS (p = 0.654), and 5-FU superiority for AKSS (p = 0.012). Study limitations Single-center study. Conclusions 5-FU and COL are effective for treating CFC, with neither showing superiority regarding the reduction in AK counts.

Infant and young child feeding knowledge and practices among mothers of under-5 children in Nadia district, West Bengal: a cross-sectional study

Background: Age-appropriate infant and young child feeding (IYCF) practice (exclusive breastfeeding till 6 months and adequate diet in a child aged 6-24 months i.e. age-appropriate number of food groups in sufficient amount and age-appropriate number of meals per day) and maintenance of hygiene are of paramount importance to promote child growth and survival. Despite several guidelines, IYCF remains an unsolved issue in the background of the significantly high proportion of malnutrition as well as under-five mortalities globally as well as in India. The current study aimed to assess the knowledge and practices related to IYCF among mothers and to find out the predictors of the same in a rural area of West Bengal. Methods: A community-based cross-sectional study was conducted among 351 mothers of under-five children in Nadia district, west Bengal with the help of a pre-designed and pre-tested semi-structured schedule. Multi-stage random sampling was done. Data were entered into MS Excel and analysed in the SPSS 21.0 version. Results: The study found that the majority (49.3% and 74.5% respectively) had an average knowledge and practice score related to infant and young child feeding. Bivariate analyses revealed that the mothers having educational levels more than higher-secondary had higher odds of good IYCF knowledge; also those who had experienced "ASHA’s home visit within one month" had higher odds of good IYCF practice. Conclusions: Adequate and consistent implementation of existing government policies can bridge the gap of knowledge and thereby practice of infant and young child feeding.
