Abstract The second-hand clothing market is a circular economy alternative to deal with excessive consumption and reduce the environmental impact caused by the fashion industry. In contrast to the vast research based on the US and Europe, this market is yet to be explored in Colombia, and in Latin America in general. This qualitative research explores the motivations to purchase second-hand clothes among young consumers aged between 20 and 33 years old residing in Medellín, Colombia. Autoethnography was conducted with these consumers. Next, a pre-existing scale of second-hand shopper motivations was used in in-depth interviews to narrate their significant experiences with second-hand clothing purchases. Findings presented two profiles of second-hand clothing consumers: on the one hand, consumers passionate about design and, on the other hand, conscious professionals who are characterized by driving their purchase intentions from hedonic to economic motivations. This research offers contributions for structuring value propositions that respond to the needs of second-hand clothing buyers.

Resumen El mercado de ropa de segunda es una alternativa de economía circular para hacer frente al consumo desmedido y disminuir el impacto ambiental causado por la industria de la moda. En Latinoamérica, y Colombia específicamente, este mercado está por explorarse porque los estudios alrededor del tema son limitados, en contraste de las múltiples publicaciones en Estados Unidos y Europa. Esta investigación cualitativa explora las motivaciones de los jóvenes de 20 a 33 años de la ciudad de Medellín, Colombia, frente al consumo de ropa de segunda. Se realizaron auto etnografías con estos consumidores, y luego, se utilizó una escala preexistente de motivaciones de compradores de segunda mano como instrumento en entrevistas a profundidad para narrar sus experiencias significativas con compras de segunda de vestuario. Los hallazgos presentaron dos perfiles de consumidores de ropa de segunda, los apasionados por el diseño y los profesionales conscientes, que se distinguen por movilizar sus intenciones de compra desde motivaciones hedónicas y económicas, respectivamente. Esta investigación ofrece contribuciones para la estructuración de propuestas de valor que respondan a las necesidades de estos compradores.

Abstract Breast cancer is the most frequently diagnosed malignant disease in women worldwide, with increasing incidence and mortality, therefore the knowledge of its risk factors is of great importance to be able to invest in effective primary prevention measures. The combined oral contraceptive (COC) is the most widely used contraceptive method in women of childbearing age, with an average use of 5 years. This systematic review aims to assess whether there is a higher incidence of breast cancer in women of childbearing age with exposure to COC for more than 5 years, compared to less than 5 years of exposure.

Resumo O cancro da mama é a doença maligna mais frequentemente diagnosticada nas mulheres em todo o mundo, com incidência e mortalidade crescentes, pelo que o conhecimento dos seus fatores de risco é de grande importância para se poder investir em medidas de prevenção primária eficazes. O contracetivo oral combinado (COC) é o método contracetivo mais utilizado em mulheres em idade fértil, com utilização média de 5 anos. Esta revisão sistemática pretende avaliar se existe maior incidência de cancro da mama em mulheres em idade fértil com exposição a COC superior a 5 anos, comparativamente a exposição inferior a 5 anos.

Abstract Background: Real-world, primary data on the treatment of psoriasis are scarce, especially concerning the role of soluble biomarkers as outcome predictors. Objective: The authors evaluated the utility of Th1/Th17 serum cytokines along with clinical characteristics as predictors of drug survival in the treatment of psoriasis. Methods: The authors consecutively included participants with moderate to severe psoriasis who were followed up for 6 years. Baseline interferon-α, tumor necrosis factor-α, and inter-leukin (IL)-2, IL-4, IL-6, IL-10, and IL-17A were measured using a cytometric bead array; clinical data were assessed. The authors calculated hazard ratios (HRs) for drug survival using a Cox proportional hazards model. Results: The authors included 262 patients, most of whom used systemic immunosuppressants or biologics. In the multivariate model, poor quality of life measured by the Dermatology Life Quality Index (HR = 1.04; 95% CI 1.01–1.07; p = 0.012) and elevated baseline IL-6 (HR = 1.99; 95% CI 1.29–3.08; p = 0.002) were associated with treatment interruption. Study limitations: The main limitation of any cohort study is the presence of confounders that could not be detected in clinical evaluation. Conclusions: Poor quality of life and elevated baseline serum IL-6 level predicted treatment interruption in patients with moderate to severe psoriasis. Although IL-6 is not the most important mediator of the inflammatory pathway in the skin environment, it is an interesting biomarker candidate for predicting psoriasis treatment response.

RESUMEN Fundamento: el estudio de las enfermedades debe integrar perspectivas e incluir variables relacionadas con los profesionales sanitarios. La aparición de nuevas enfermedades como la COVID-19 ha generado un grupo de investigaciones dirigidas a los profesionales y estudiantes inmersos en su prevención y control. Objetivo: caracterizar las actitudes de los estudiantes de Enfermería vinculados al pesquisaje activo de casos sintomáticos de COVID-19. Métodos: en la universidad médica camagüeyana se realizó un estudio descriptivo, transversal, en el período de marzo a mayo de 2021, con la combinación de metodologías cualitativas. Se aplicaron métodos teóricos para la fundamentación de la investigación y empíricos como la observación externa directa, entrevista semiestructurada y composición, a una muestra de 30 estudiantes de licenciatura en Enfermería. Resultados: las actitudes se caracterizaron por tener una dirección que no indicó rechazo abierto, pero se percibió la dificultad de abordar el tema de la posibilidad del propio contagio en el 49,30 %. Hubo un 62,10 % de inconsistencia interna en las actitudes, al constatarse una relación antagónica entre sus componentes. Conclusiones: la vinculación de los estudiantes de Enfermería a escenarios clínicos y comunitarios permitió la identificación de características en sus componentes, consistencia o funciones que implican exposición a situaciones de riesgo o limitan el desempeño; es imprescindible modificarlas en aras de garantizar las acciones de sostenibilidad y la formación profesional.

ABSTRACT Background: the study of diseases must integrate perspectives and include variables related to health professionals. The emergence of new diseases such as COVID-19 has generated a group of research aimed at professionals and students immersed in its prevention and control. Objective: to characterize the attitudes of nursing students linked to active screening in cases of COVID-19. Methods: a descriptive, cross-sectional study was carried out at Camagüey Medical University from March to May 2021, with a combination of qualitative methodologies. Theoretical methods were applied to support the research and empirical methods, such as direct external observation, semi-structured interviews and composition, to a sample of 30 undergraduate Nursing students. Results: the attitudes were characterized by having a direction that did not indicate open rejection, but the difficulty of addressing the issue of the possibility of contagion itself was perceived in 49.30%. There was 62.10% of internal inconsistency in attitudes, as an antagonistic relationship was found among its components. Conclusions: the linking of Nursing students to clinical and community settings allowed the identification of characteristics in their components, consistency or functions that imply exposure to risk situations or limit performance; it is essential to modify them in order to guarantee sustainability actions and professional training.

Abstract The aim of this study was to assess the in vitro ovicidal activity of an ethyl acetate extract from Arceuthobium vaginatum (EtOAc-E) and their subfractions (AvR5-AvR14) against Haemonchus contortus using the egg hatching inhibition (EHI) test. The EtOAc-E and subfractions were tested at 0.12-2.00 and at 0.015-2.0 mg/mL, respectively. Distilled water and methanol (2%) were used as negative controls and Thiabendazole (0.10 mg/mL) as a positive control. Treatments with a dependent effect on concentration were subjected to regression analysis to determine the effective concentrations (EC50 and EC90). The major secondary compounds present in the extract and subfractions were identified by high performance liquid chromatography (HPLC). The EtOAc-E and AvR9 exhibited the best ovicidal effect recording 97.5 and 100% of EHI at 0.25 mg/mL, respectively. The EtOAc-E and AvR9 displayed an EC50= 0.12 and 0.08 mg/mL, respectively. The HPLC analysis in the EtOAc-E and bioactive fractions indicated the presence of a polyphenol, glycosylated flavanones, quercetin glucoside, cinnamates, coumarin, cinnamic acid derivative, ferulic acid, coumarate, naringenin, protocatechuic acid and naringin. Results demonstrated that A. vaginatum extract and fraction is able to inhibit the egg hatch process of H. contortus and could be a viable option for the control of small ruminant haemonchosis.

Resumo O objetivo deste estudo foi avaliar a atividade ovicida in vitro de um extrato de acetato de etila de Arceuthobium vaginatum (EtOAc-E) e suas subfrações (AvR5-AvR14) contra Haemonchus contortus, utilizando-se o teste de inibição da eclosão de ovos (EHI). O extrato foi testado em 0.12-2.00 mg/mL, e as subfrações foram testadas em 0.15-2.0 mg/mL. Água destilada e metanol (2%) foram utilizados como controles negativos e Tiabendazol (0.10 mg/mL) como controle positivo. Os tratamentos com efeito concentração dependente foram submetidos à análise de regressão para determinação das concentrações efetivas (CE50 e CE90). Os principais compostos secundários, presentes no extrato e nas subfrações, foram identificados por cromatografia líquida de alta eficiência (HPLC). EtOAc-E e subfração AvR9 exibiram o melhor efeito ovicida, registrando-se 97.5 e 100% do EHI a 0.25 mg/mL, respectivamente. O EtOAc-E e AvR9 apresentaram CE50= 0,12 e 0,08 mg/mL, respectivamente. A análise por HPLC nas frações EtOAc-E e bioativas indicou a presença de um polifenol, flavanonas glicosiladas, glicosídeo de quercetina, cinamatos, cumarina, derivado de ácido cinâmico, ácido ferúlico, cumarato, naringenina, ácido protocatecuico e naringina. Os resultados demonstraram que extrato e frações de A. vaginatum são capazes de inibir o processo de eclosão dos ovos de H. contortus, podendo ser uma opção viável para o controle da hemoncose em pequenos ruminantes.

Resumo Introdução: As lesões vasculares iatrogénicas são uma causa importante de morbilidade e mortalidade após intervenções cirúrgicas ortopédicas ou neurocirúrgicas. Neste artigo, os autores apresentam dois casos clinicos de quasi-iatrogenia vascular. Casos clínicos: Dois casos, um procedimento ortopédico e um procedimento neurocirúrgico, são apresentados. O primeiro caso refere-se a uma mulher de 80 anos com migração do componente acetabular de uma prótese da anca, associado a trombose da veia ilíaca externa. O segundo caso reporta um homem de 27 anos com compressão medular ao nível de D6 por motivo de um hemangioma ósseo. Após a operação, verificou-se a presença de material de fixação (parafuso) fazendo protusão para o lúmen da aorta torácica. Este foi removido num segundo momento. Ambas as operações decorreram sem complicações. Conclusão: Os autores consideram que uma abordagem multidisciplinar contribuiu significativamente para o sucesso dos casos apresentados.

Abstract Introduction : Primary hypophysitis (PH) is a rare disease that represents a challenge among differential diagnosis and management. Our aim was to describe clinical characteristics, diagnostic criteria and different treatment outcomes in patients with PH. Multicentric, retrospective study. Clinical presentation, endocrine function, magnetic resonance imaging findings, visual field defects at diagnosis and treatment outcomes were recorded. Methods : Twenty-eight patients (23 women), with PH were included. Median age: 37. Results : The most frequent symptoms: headache: 68%, polyuria-polydipsia: 50% and visual disturbances: 48%. At diagnosis, anterior pituitary deficiency was present in 71%, being hypogonadotrophic hypogonad ism the most frequent manifestation. The radiological findings: symmetric lesion: 78.5%, homogeneous en hancement: 78.5% and pituitary stalk thickening: 70%. Association with pregnancy or puerperium was found in 4/23 women (17%). Fourteen patients did not receive any treatment (“wait and see” group), 8 underwent surgery for mass reduction or resection and 6 were treated with immunosuppression therapy. Among 15 patients with histopathological diagnosis, 9 were lymphocytic hypophysitis, 5 IgG4 related hypophysitis and 1 xanthomatous hypophysitis. Thirteen were di agnosed by established clinical criteria. Mass reduction was observed in 43% of “wait and see group” patients, 62.5% of operated patients and 50% with immuno suppression therapy. Compressive symptoms showed improvement in the 3 groups, with modest effect on anterior pituitary function, diabetes insipidus did not resolve in any patients. Discussion : In patients without severe compressive symptoms, we adopted a “wait and see” approach. In patients with uncertain diagnosis of PH or severe com pressive symptoms, transsphenoidal surgery was the best option.

ABSTRACT Background: Hypersensitivity reactions during chemotherapy have been increasingly documented in children. Drug desensitization is an unknown procedure for most oncologists, despite allowing patients to be treated with first-line agents, affecting the final prognosis. Currently, there are no guidelines for drug desensitization in pediatric age, and the general principles adopted for adults have been applied to children. Objective: To describe the experience of an Immunoallergology department of a central hospital in the desensitization to carboplatin and methotrexate in pediatric age. Results: Desensitizations were performed on carboplatin in 17 patients, in a total of 112 procedures, and on methotrexate in 4 children, with a success rate of 88% for carboplatin and 100% for methotrexate. Conclusion: As far as the authors are aware, this is the largest European series of desensitizations to chemotherapy in pediatric age, including procedures in infants and in non-immediate reactions.

RESUMO Fundamentos: As reações de hipersensibilidade durante a quimioterapia em crianças têm sido documentadas de forma crescente. A dessensibilização a fármacos é um procedimento desconhecido por grande parte dos oncologistas, apesar de permitir que os doentes sejam tratados com agentes de primeira linha, afetando o prognóstico final. Atualmente, ainda não existem normas de orientação de dessensibilização a fármacos em idade pediátrica e os princípios gerais adotados para os adultos têm sido aplicados em crianças. Objetivo: Descrever a experiência de um serviço de imunoalergologia de um hospital central na dessensibilização à carboplatina e ao metotrexato em idade pediátrica. Resultados: Foram realizadas dessensibilizações à carboplatina em 17 crianças, num total de 112 procedimentos, e ao metotrexato em 4 crianças, com uma taxa de sucesso de 88% para a carboplatina e de 100% para o metotrexato. Conclusão: Tanto quanto é do conhecimento das autoras, esta é a maior série europeia de dessensibilizações a quimioterápicos em idade pediátrica, tendo sido realizadas, inclusivamente, procedimentos num lactente e numa reação não imediata.

Resumen Antecedentes: La pandemia ha afectado al bienestar psicológico y a la sexualidad de la población, especialmente entre grupos vulnerables como los hombres de una minoría sexual. Método: En España, un total de 320 hombres heterosexuales y 151 hombres de minorías sexuales, de entre 18 y 60 años, respondieron un cuestionario online ad hoc sobre comportamiento sexual durante el confinamiento. Resultados: Durante el confinamiento, respecto a los hombres heterosexuales, los hombres de minorías sexuales se masturbaron más, realizaron más actividades sexuales en línea y tuvieron más sexo con no convivientes. En cambio, los hombres heterosexuales tuvieron más relaciones sexuales con su pareja. El hecho de vivir en pareja durante el confinamiento fue predictor de una mejoría de la vida sexual, sobre todo para los hombres heterosexuales. Además, el impacto emocional del confinamiento fue predictor de un empeoramiento de la vida sexual sin distinción por orientación sexual. Conclusiones: En futuras intervenciones habría que tener en cuenta que la vida sexual de los hombres está mediada por el impacto emocional del momento, especialmente entre los hombres de minorías sexuales, ya que su calidad de vida sexual muestra menor relación con algunas de las variables protectoras estudiadas (vivir en pareja).

Abstract Background: The pandemic affected the psychological well-being and sexuality of the population, especially among vulnerable groups such as men from sexual minorities. Method: In Spain, a total of 320 heterosexual men and 151 sexual minority men, aged between 18 and 60, answered an ad hoc online questionnaire about sexual behavior during the lockdown. Results: Compared to heterosexual men, during the lockdown, sexual minority men masturbated more, engaged in more sexual activities online, and had more sex with non-cohabitants. Heterosexual men had more sexual relations with their partners. Living with a partner during the lockdown predicted an improvement in sex life, especially for heterosexual men. Furthermore, the emotional impact of lockdown was a predictor of a worsening sex life regardless of sexual orientation. Conclusions: Future interventions should take into account that men's sex lives are mediated by the emotional impact of the moment, especially among sexual minority men, since the quality of their sex life shows a weaker relationship with some of the protective variables studied (living with a partner).

Resumen Esta revisión de la literatura acerca de la narrativa y sus aportes a la construcción social del conocimiento se propone investigar qué puede aportar la primera desde su posicionamiento teórico-metodológico. A través de la revisión de diferentes textos que hablan sobre la narrativa como un acercamiento epistemológico a la sociedad y a las interrelaciones humanas, el texto busca exponer y analizar qué favorece y potencia la investigación narrativa en términos de construcción de conocimientos. Asimismo, pretende determinar por qué es importante generar y recuperar las voces subjetivas del individuo y de las colectividades para abrir posibilidades en el campo de lo social y de lo educativo.

Abstract This review of the literature on narrative and its contributions to the social construction of knowledge aims to investigate what narrative can contribute from its theoretical-methodological position. Through the review of different texts that talk about narrative as an epistemological approach to society and human relationships, the text seeks to expose and analyze what favors and enhances narrative research in terms of knowledge construction. Likewise, it tries to determine why it is important to generate and recover the subjective voices of the individual and of the collectivities to open possibilities in the social and educational field.

Abstract Objective: To detect and quantify glyphosate residues in breakfast cereals marketed in the city of Saltillo, Coahuila. Materials and Methods: Two samples of 12 different cereal brands were analyzed. A Soxhlet apparatus was used for pesticide extraction and quantification was performed by High Performance Liquid Chromatography (HPLC) using an Agillent model 1100 Series equipment coupled to a UV- Vis detector. Results: Glyphosate was detected in 100% of the samples analyzed, with concentrations ranging from 170 to 2 400 mg/kg; the samples with the highest concentrations were those of international brands. Conclusions: All the concentrations detected in the commercial cereal samples exceeded the MRLs established in CODEX ALIMENTARIUS, so it is important to carry out more studies in order to monitor and ensure the safety of the processed products that are consumed.

Abstract This article aims to add to the understanding of the challenges involved in designing digital texts to promote multiliteracies pedagogy. A multiliteracies approach calls for multimodal meaning-making and cultural diversity to be integrated into new school curriculum content, and accordingly, we analyse an interactive children’s story app, named Mobeybou in Brazil. The research question addressed was: what can we learn about the design of multimodal texts aimed at promoting intercultural learning from the design of this story app? The app incorporates tangible and digital storytelling materials to promote intercultural skills among young children, focusing specifically on Brazil. Mobeybou in Brazil was studied to characterize the design of its multimodal representations of meaning, using categories from the grammar of storytelling and multimodal meaning-making, particularly those concerned with representing the experiential diversity and personal positioning of the app users. The findings provide evidence of the complexity involved in designing multimodal texts to meet the challenges of promoting multiliteracies pedagogy, highlighting the urgent need to narrow the interface between research undertaken in education, semiotics, and digital media design. The article concludes by identifying the study’s limitations and some future developments.

Resumo Este artigo pretende contribuir para a compreensão dos desafios colocados pelo design de textos digitais especificamente destinados a promover a pedagogia das multiliteracias. Esta abordagem pedagógica defende que a compreensão e produção de significados multimodais e a diversidade cultural são conteúdos incontornáveis no novo currículo escolar. Apresentamos o estudo de uma story app multimodal interativa, intitulada Mobeybou no Brasil, desenvolvida para dar resposta à seguinte questão de investigação: o que se pode aprender sobre o design de textos multimodais destinados a promover a aprendizagem intercultural a partir do design desta story app? Na nossa análise, utilizamos categorias da gramática da narrativa e da representação multimodal incidentes na representação da diversidade experiencial e do posicionamento pessoal dos utilizadores. Os resultados sugerem a complexidade envolvida no design de textos multimodais que respondem aos desafios da pedagogia das multiliteracias, salientando a necessidade urgente do estreitamento da colaboração entre a investigação realizada nas áreas da educação, da semiótica e do design de média digitais. Por fim, identificamos as limitações do estudo, apontando alguns desenvolvimentos futuros.

Abstract Objective: to assess the evolution of adherence to Mediterranean diet and level of physical activity of university students of Health Sciences in Castilla-La Mancha during the COVID-19 lockdown and one year afterwards. Methods: a cross-sectional observational study using questionnaires on adherence to the Mediterranean diet and level of physical activity. A total of 893 students enrolled in Health Sciences degrees at the University of Castilla la Mancha participated, 575 in the first survey (during the lockdown) and 318 in the second (one year later). By sex, 672 women and 221 men (in the first survey 77.7 % were women and 22.3 % men while in the second survey these were 70.8 % and 29.2 %, respectively). Adherence to the Mediterranean diet was assessed with the Mediterranean Diet Adherence Screener (MEDAS) questionnaire and the modified Prevention with Mediterranean Diet (PREDIMED) questionnaire. The level of physical activity was assessed with the Rapid Assessment of Physical Activity Scale (RAPA). Results: one year after the COVID-19 confinement, consumption of olive oil has almost tripled. Daily fruit consumption has also doubled. Similarly, the consumption of wine and alcoholic beverages has doubled. Conversely, there was a reduction in the consumption of butter and margarine, as well as of carbonated drinks and sweetened beverages. Likewise, the percentage of university students with high adherence to the Mediterranean diet increased significantly (from 26 % to 34.3 %). Regarding physical activity level, there was a significant increase in the percentage of university students who engaged in light, moderate and even intense physical activity on an irregular basis. This increase was not found in the case of muscular strength and flexibility training activities. Conclusion: the results of the study indicate that, although the levels of adherence to the Mediterranean diet and physical activity have improved after the COVID-19 confinement, adherence to Mediterranean diet and physical activity level among the university population analyzed is still low. It is necessary to implement strategies for the achievement or maintenance of a healthy lifestyle in this population.

Resumen Objetivo: valorar la evolución de la adherencia a la dieta mediterránea y el nivel de actividad física de los estudiantes universitarios de Ciencias de la Salud de Castilla-La Mancha durante la pandemia de COVID-19 y un año después de la misma. Método: estudio observacional transversal mediante cuestionarios sobre la adherencia a la dieta mediterránea y el nivel de actividad física. Participaron 893 alumnos matriculados en grados de Ciencias de la Salud de la Universidad de Castilla-La Mancha, 575 en la primera encuesta (durante la pandemia) y 318 en la segunda (un año después). Por sexos, 672 mujeres y 221 hombres (en la primera encuesta, el 77,7 % eran mujeres y el 22,3 % hombres, mientras que en la segunda lo eran el 70,8 % y 29,2 %, respectivamente). La adherencia a la dieta mediterránea se valoró con el cuestionario Mediterranean Diet Adherence Screener (MEDAS) y el cuestionario de Prevención con Dieta Mediterránea (PREDIMED), modificado. El nivel de actividad física se valoró con el cuestionario Rapid Assessment of Physical Activity Scale (RAPA). Resultados: tras un año desde el confinamiento por la COVID-19, el consumo de aceite de oliva casi se ha triplicado. Se ha duplicado también el consumo de frutas diario. De igual modo, se ha duplicado el consumo de vino y bebidas alcohólicas. Por el contrario, se encontró una reducción del consumo de mantequilla y margarina, al igual que de bebidas carbonatadas y azucaradas. Asimismo, aumentó significativamente el porcentaje de estudiantes universitarios con adherencia alta a la dieta mediterránea (del 26 % al 34,3 %). En cuanto al nivel de actividad física, ha aumentado significativamente el porcentaje de estudiantes universitarios que realizan actividad fisica ligera, moderada e incluso intensa de forma irregular. Este aumento no se ha encontrado en el caso de las actividades de fuerza muscular y flexibilidad. Conclusión: los resultados del estudio nos indican que, aunque los niveles de adherencia a la dieta mediterránea y de actividad física han mejorado tras el confinamiento por la COVID-19, la adherencia a la dieta mediterránea y el nivel de actividad física de la población universitaria analizada siguen siendo bajos. Es necesario aplicar estrategias para la consecución o mantenimiento de un estilo de vida saludable en dicha población.
