RESUMEN

Purpose: We aimed to explore student perspectives of the dietetics profession using a professional socialization lens.Methods: We conducted qualitative semi-structured interviews, virtually or by phone, with 25 dietetic undergraduate/graduate students or interns in 2020/21. Transcripts were thematically analyzed.Results: All participants identified as female, averaged 25 years old at the time of the interviews, and were in different stages of their education. Two themes captured their perspectives of the profession: dietitians have technical expertise and professional identities are evolving. Technical expertise was focused on scientific understandings of how individuals consume and utilize food, and how (mostly Western) food should be prepared for safety and maximum nutrition. Participants perceived dietetics as a white, feminized profession with dietitians' role to aid in weight loss; participants actively sought to resist these stereotypes, notably through social media.Conclusions: While holding technical expertise continues to be embedded as a key component of dietetics identity, student professional socialization is also being shaped by social media, racial justice, and body positivity movements. This socialization process is likely to influence changes to the profession as students enter practice.

RESUMEN

Investigating the growing concern of pediatric burn injuries caused by social media challenges. Adolescents, seeking fame or succumbing to peer pressure, engage in risky behaviors, recording and sharing them online. The study presents two case reports detailing severe burn injuries resulting from such challenges, highlighting the physical and psychological toll on affected children and their families. In Case report 1, a 14-year-old suffered severe burns attempting a TikTok challenge involving igniting a soaked t-shirt. The patient's critical condition necessitated intensive care, surgical procedures, and skin grafts, accompanied by complications like anemia and sepsis. Case report 2 features a 9-year-old who sustained extensive burns while attempting another social media challenge. Treatment included escharolysis, skin grafts, and surgeries, with complications managed during the recovery process. A literature review explores social media-generated burn injuries, revealing their physical and psychological impact. The influence of social proof and peer pressure on adolescents' behavior in the digital age is discussed. The pandemic's effect on mental health is considered, emphasizing the vulnerability of adolescents to such challenges. In conclusion, the paper highlights the rising incidence of teen burn injuries linked to social media challenges. Urgent measures are needed to restrict the promotion of risky behaviors on social platforms. Alongside state-of-the-art burn treatments, comprehensive psychological care is essential for young patients and their families to cope with trauma. Increased content monitoring and the dissemination of prevention materials are recommended to mitigate the occurrence of such incidents.

RESUMEN

This study explores vulnerability narratives used in relation to older adults and others during the COVID-19 pandemic. A mixed-method content analysis was conducted of 391 articles published in two major newspapers in Canada and the USA during the first wave of the pandemic. The findings indicated that during the early months of the pandemic, limited attention was directed towards its impact on older adults or other 'vulnerable' subpopulations in both countries. Where evident, intrinsic (individual-level) risk factors were most consistently used to frame the vulnerability of older adults. In contrast, vulnerability was more likely to be framed as structural with regard to other subpopulations (e.g., ethno-racial minorities). These narratives also differed somewhat in Canadian and US newspapers. The framing of older adults as intrinsically vulnerable reflects ageist stereotypes and promotes downstream policy interventions. Greater attention is needed to the role of structural factors in influencing pandemic-related outcomes among older adults.

RESUMEN

Introducción:Evaluar la prevalencia y el impacto del uso de líneas medias canalizadas por el Equipo de Infusión y Accesos Vasculares mediante punción eco-guiada comparada con la es-trategia endovenosa convencional (punción de catéter venoso periférico por enfermeras de hospitalización) en una unidad de nefrología y trasplante renal.Material y Método: Estudio observacional retrospectivo. Se compararon 3 periodos: pre-implantación, implantación y consolidación del Equipo de Infusión y Accesos Vasculares. Se incluyeron todos los pacientes ingresados en las unidades de hospitalización de Nefrología y Trasplante Renal que requirie-ron de la colocación de catéteres vasculares periféricos y línea media. Se analizó la prevalencia de acceso venoso, el tiempo de permanencia y los motivos de retirada (complicaciones).Resultados: La incidencia de los catéteres vasculares perifé-ricos fue decreciente mientras que el de las líneas medias se incrementó progresivamente en los tres períodos. Así mismo, no se observaron diferencias en el tiempo medio de perma-nencia de los catéteres vasculares periféricos mientras que la permanencia de días de la línea media se incrementó.Se confirma en todos los periodos una tasa de complicaciones más elevada y variable en los catéteres vasculares periféricos; mientras que en la línea media la tasa de complicaciones fue menor y más estable.Conclusiones: La implementación de un programa de terapia intravenosa en pacientes nefrológicos ha permitido minimizar el número de dispositivos venosos por paciente, con la conse-cuente reducción de punciones durante el ingreso, así como la disminución de las complicaciones asociadas a la canaliza-ción venosa (menor morbilidad).Palabras clave: Equipo de Infusión y Accesos Vasculares (EIAV); Líneas Medias (LM); Catéteres Vasculares Periféricos (CVP); complicaciones; paciente nefrológico.

Objective:To evaluate the prevalence and impact of midline catheters inserted by the Infusion and Vascular Access Team using echo-guided puncture compared to conventional intra-venous strategies (peripheral venous catheter insertion by hospitalization nurses) in a nephrology and kidney transplant unit.Material and Method: This is a retrospective observational study. Three periods were compared: pre-implementation, implementation, and consolidation of the Infusion and Vas-cular Access Team. All patients admitted to the Nephrology and Kidney Transplantation hospitalization units requiring the placement of peripheral vascular catheters and midline were included. The prevalence of venous access, dwell time, and reasons for removal (complications) were analyzed. Resultados: The incidence of peripheral vascular catheters decreased while that of midlines progressively increased in all three periods. Moreover, there were no differences in the mean dwell time of peripheral vascular catheters, whereas the dwell time of midlines increased. A higher and variable rate of complications was confirmed in peripheral vascular catheters in all periods, while in midlines, the complication rate was lower and more stable.Conclusions: Implementing an intravenous therapy program in nephrology patients has allowed for minimizing the num-ber of venous devices per patient, resulting in a reduction in punctures during hospitalization and a decrease in com-plications associated with venous cannulation (lower mor-bidity).

RESUMEN

OBJECTIVE: Responsible media reporting is an accepted strategy for preventing suicide. In 2015, suicide prevention experts launched a media engagement initiative aimed at improving suicide-related reporting in Canada; its impact on media reporting quality and suicide deaths is unknown. METHOD: This pre-post observational study examined changes in reporting characteristics in a random sample of suicide-related articles from major publications in the Greater Toronto Area (GTA) media market. Articles (n = 900) included 450 from the 6-year periods prior to and after the initiative began. We also examined changes in suicide counts in the GTA between these epochs. We used chi-square tests to analyse changes in reporting characteristics and time-series analyses to identify changes in suicide counts. Secondary outcomes focused on guidelines developed by media professionals in Canada and how they may have influenced media reporting quality as well as on the overarching narrative of media articles during the most recent years of available data. RESULTS: Across-the-board improvement was observed in suicide-related reporting with substantial reductions in many elements of putatively harmful content and substantial increases in all aspects of putatively protective content. However, overarching article narratives remained potentially harmful with 55.2% of articles telling the story of someone's death and 20.8% presenting an other negative message. Only 3.6% of articles told a story of survival. After controlling for potential confounders, a nonsignificant numeric decrease in suicide counts was identified after initiative implementation (ω = -5.41, SE = 3.43, t = 1.58, p = 0.12). CONCLUSIONS: We found evidence that a strategy to engage media in Canada changed the content of reporting, but there was only a nonsignificant trend towards fewer suicides. A more fundamental change in media narratives to focus on survival rather than death appears warranted.

RESUMEN

O presente artigo explora alguns impactos políticos e sociais reconhecidos nos dez anos que sucederam as manifestações de junho de 2013, dando ênfase a um fator específico: o papel das mídias sociais no cenário político e na mobilização de grupos. Partindo desse foco, trata da possibilidade de que tais ferramentas digitais possam ser melhor exploradas por certos grupos políticos em detrimento de outros, e os motivos para tanto. Tal questão será discutida a partir de autores de estudos da tecnologia, da teoria social e da psicanálise. Não necessariamente inferindo uma diferenciação de conteúdo de ideologias políticas, propomos essa distinção considerando que os impactos subjetivos e de mobilização produzidos por tais mídias podem ser assimilados e empregados de acordo com objetivos específicos. Trata-se, assim, de um exame sobre os impactos que as mídias sociais produzem em processos de subjetivação e de agrupamento, e seus efeitos políticos.

Resumos This paper explores political and social impacts present in the ten years since June 2013 demonstrations, emphasizing an specific factor: the role of social media in the political landscape and in mobilizing groups. We take as a central question the possibility that those digital tools are better explored by some political groups to the detriment of others, and the reasons that explain this difference. This question is developed with authors from the studies of technology, social theory, and psychoanalysis. Without necessarily assuming a content differentiation among political views, we propose their distinction considering that the subjective and the mobilizing impacts produced by these media can be assimilated and employed according to specific objectives. Therefore, this study is an examination of the impacts that social media produce on subjectivation and grouping processes, and their political effects.

Cet article explore certains des impacts politiques et sociaux constatés au cours des dix années qui ont suivi les manifestations de juin 2013, en mettant l'accent sur un facteur spécifique: le rôle des médias sociaux dans le paysage politique et dans la mobilisation des groupes. À partir de là, il aborde la possibilité que ces outils numériques puissent être mieux exploités par certains groupes politiques au détriment d'autres, et les raisons de cette différence supposée. Cette question sera discutée à l'aide d'auteurs issus des études technologique, de la théorie sociale et de la psychanalyse. Sans nécessairement en déduire une différenciation dans le contenu des opinions politiques, nous proposons cette distinction en considérant que les impacts subjectifs et mobilisateurs produits par ces médias peuvent être assimilés et utilisés en fonction d'objectifs spécifiques. Il s'agit donc d'examiner les impacts que les médias sociaux produisent sur les processus de subjectivation et de regroupement, et leurs effets politiques.

A partir de este foco, se aborda la posibilidad de que estas herramientas digitales sean mejor exploradas por unos grupos políticos que por otros, y las razones que explican esta diferencia. Para discutir esta cuestión se utiliza autores de la filosofía de la tecnología, de la teoría social y del psicoanálisis. Sin asumir necesariamente una diferenciación de contenido entre ideologías políticas, se propone esta distinción teniendo en cuenta que los impactos subjetivos y de movilización que producen estas herramientas digitales pueden ser asimilados y empleados de acuerdo con objetivos específicos. Se trata, por tanto, de un examen sobre los impactos que las redes sociales producen en los procesos de subjetivación y agrupación, y sus efectos políticos.

RESUMEN

Background Among the various mechanical and biological properties of luting cement, the most important are its resistance to disintegration, degradation, and stability in the oral cavity. The sorption and solubility of cement alter the mechanical properties by impeding the half-life of the filling. It also leads to variations in dimensions, discoloration, and margin breakage. It is, therefore, essential to choose a low-solubility cement since there is always an interaction between teeth and restorative margins. The aim of this study is to assess and compare the solubility and sorption values of three different luting cements in three liquid media. Materials and methods Three luting cements were used for the investigation. Disc-shaped specimens of the cement, which were of 10 mm diameter and 2 mm height, were prepared. The sample included a total of 126 disc-shaped specimens made up of three materials, glass ionomer cement (GIC), resin cement, and resin-modified GIC, which were used in three liquid media (14 of each material in each medium). Fourteen specimens of each material were placed in glass vials containing 20 ml of each medium: distilled water, artificial saliva, and carbonated water. The samples were then put in an incubator at 37 °C. The measurements and masses of the samples were documented on days one, three, seven, 14, 21, 28, and 35. The samples were taken out of the solution after five weeks and stored in a desiccator with calcium sulphate for another five weeks. The weight and dimensional changes were estimated on days one, three, seven, 14, 21, 28, and 35. The values of water sorption (WSO) and solubility (WSL) were estimated. To determine the mean and standard deviation of each cohort, descriptive statistics were employed. Utilizing the Shapiro-Wilkinson test, the normality was determined. An independent test was used to determine the difference between all pairs of groups, while one-way ANOVA, Dunn test, and post hoc analysis were used to establish the distinction between the three groups. Results One-way ANOVA showed that significant differences existed among the groups: resin cement showed the least sorption and solubility, resin-modified GIC showed the highest solubility in distilled water (0.40 ± 0.03), and GIC showed the highest solubility in both artificial saliva (0.36 ± 0.03) and carbonated water (0.04 ± 0.05). Conclusion Considering the experimental outcomes and the limitations of an in vitro investigation, it was concluded that in the complex setting of the oral environment, this selection procedure is crucial for maintaining mechanical strength and for the long lifespan of dental restorations.

RESUMEN

Is a general theory of memory possible? What contribution can sociology make to this vast scientific project? Two original contributions are presented and discussed in this article: (1) the concept of collective memory (Maurice Halbwachs); (2) the concept of social memory (Niklas Luhmann). The author proposes some important theoretical clarifications. First, memory is neither a stock nor a collection (of past states or events) but rather a continuous operation of sorting between remembering and forgetting. Secondly, collective memory is not social memory: indeed, the former is a specific operation of psychic systems whereas the latter is an operation of communication, specific to social systems. In the particular case of the attacks of November 13, 2015 in Paris, the author shows the function of social memory that the mass media system fulfills and how these operations of filtering meaning condition the construction of traumatic memories.

Title: Mémoire collective et mémoire sociale : apports de la sociologie à une théorie générale de la mémoire. Abstract: Une théorie générale de la mémoire est-elle possible ? Quelle contribution la sociologie peut-elle apporter à ce vaste projet scientifique ? Deux contributions originales sont présentées et discutées dans cet article : (1) le concept de mémoire collective (Maurice Halbwachs) ; (2) le concept de mémoire sociale (Niklas Luhmann). L'auteur propose quelques clarifications théoriques importantes. D'abord, la mémoire n'est ni un stock ni une collection (d'états ou d'événements passés) mais plutôt une opération continue de tri entre souvenir et oubli. Ensuite, la mémoire collective n'est pas la mémoire sociale : en effet, la première est une opération spécifique des systèmes psychiques ; quant à la seconde, elle est une opération de communication, propre aux systèmes sociaux. Dans le cas particulier des attentats du 13 novembre 2015 à Paris, l'auteur montre la fonction de mémoire sociale que remplit le système des médias de masse et comment ces opérations de filtrage du sens conditionnent la construction de souvenirs traumatiques.

RESUMEN

Gaps in communication training have been identified in Canadian and international academic and practicum dietetics programs. A workshop was developed to pilot supplementary media training to nutrition students/trainees studying in Nova Scotia. Students, interns, and faculty from two universities participated in the workshop. Data on perceived learning, media knowledge/skill use, and workshop feedback were collected immediately post-workshop using a mixed-form questionnaire. A modified questionnaire was administered eight months post-workshop to obtain information on utility of the perceived acquired knowledge/skills. Closed-ended responses underwent descriptive analysis, while open-ended responses underwent thematic analysis. Twenty-eight participants completed the questionnaire post-workshop, and six completed it at follow-up. All participants rated the workshop positively (7-point Likert scale) and reported learning something new (perceived). Perceived learning emphasized general media knowledge/skills and communication skills. Follow-up data suggested participants had applied perceived media knowledge/skills in message development and media and job interviews. These data suggest that nutrition students/trainees may benefit from supplementary communications and media training and provide a stimulus for ongoing curriculum review and discussion.

RESUMEN

The Mediterranean is one of the most overfished seas of the world where mesopredators are severely threatened. The trophic strategies of four pelagic species that inhabit the Adriatic Sea (Scomber spp. and Trachurus spp.) were investigated through an integrated approach of stomach contents and stable isotopes analyses. Our study demonstrated that Scomber colias feeds mainly on strictly pelagic prey, with fish larvae as a secondary prey in the Southern Adriatic Sea, while S. scombrus feeds on prey belonging to higher trophic levels. Smaller specimens of Trachurus mediterraneus have a diet mainly based on pelagic prey, while larger fishes rely on prey such as benthic decapods, showing an ontogenetic shift in the diet of the species. Trachurus trachurus shows a preference for offshore and deeper areas and a diet such as that of its congeneric, but no clear ontogenetic shift was observed. This spatial segregation allows the co-existence of these two species of Trachurus. Scomber colias mainly inhabits southern areas and S. scombrus shows a preference for the northern sectors. This latitudinal gradient avoids the overlap of their trophic niches. Bayesian mixing models confirmed that the trophic niches of these species only partially overlap in the middle of the trophic web.

RESUMEN

BACKGROUND: YouTube has remained the most commonly used online platform and is increasingly used for health education. Although videos related to diabetic retinopathy on YouTube are abundant, there is still a paucity of research regarding the detailed analysis of their quality and content. PURPOSE: This study aims to assess the content, sources, and overall usefulness of information published on the YouTube platform regarding diabetic retinopathy (DR). METHODS: The YouTube website was systematically searched using the keyword "diabetic retinopathy" between August 14 and September 29, 2021. RESULTS: A total of 465 videos related to DR were included in our analysis. Of these videos, 215 (46.4%) videos were released from the United States. The highest number of videos were uploaded by medical websites (32.9%), followed by hospitals/medical centers (23%). Educational videos on DR including basic information, complications, treatment, staging and retinal photographs were the most frequent category. Videos containing basic information, complications and videos with animation on DR received the highest numbers of views (2,768,062, 2,361,999, and 1,946,586, respectively). Videos uploaded by hospitals/medical centers received a high mean number of views, likes, and dislikes. Overall, 72.5% of videos on DR published on YouTube were considered largely useful. CONCLUSIONS: Videos published by medical websites, hospitals/medical centers and those pertaining to basic information, complications, and animation on DR were the most attractive. Hence, these types of videos can be targeted to increase awareness about DR.

RESUMEN

Os bebês, hoje, vêm sendo expostos às telas já durante o primeiro ano de vida. Essa exposição é possibilitada pelos adultos, que por diferentes razões, disponibilizam para as crianças seus próprios smartphones ou outros dispositivos. E o que será que pais e profissionais da educação infantil pensam sobre a exposição do bebê às telas? Para explorar a percepção dos cuidadores de bebês com até 3 anos sobre como as novas tecnologias permeiam as rotinas familiar e escolar e afetam o desenvolvimento infantil, assim como propiciar um espaço de escuta, psicoeducação e reflexão, uma intervenção clínica foi proposta. Foram realizados encontros com cuidadores de bebês em uma escola de educação infantil na região metropolitana de Porto Alegre, RS, Brasil. Os encontros transcorreram na modalidade roda de conversa e possibilitaram importantes reflexões sobre um tema que reverbera na saúde mental das crianças e nas interações com seus cuidadores.

It is already known that babies are often exposed to screens during their first year of life. This exposure is mediated by adults, who hand their smartphones or other devices to children for several reasons. What do parents and school caregivers think about a baby's screen exposure? To explore the perceptions of caregivers of babies up to 3 years old about how new technologies pervade family and school routines, affecting children's development, and to provide an opportunity for listening, psychoeducation and reflections, a clinical intervention was proposed. The intervention took place in a kindergarten school located in the metropolitan region of Porto Alegre, RS - Brazil, during three group sessions, using a conversation wheel. The group intervention enabled caregivers to discuss an important theme, which affects the baby's development and relationships.

La exposición de los bebés a pantallas generalmente ocurre durante el primer año de vida del bebé y es facilitada por los adultos. Teniendo en cuenta lo anterior, ¿qué piensan padres, madres y profesores? Para responder a esa cuestión una intervención clínica buscó explorar lo que piensan padres, madres y profesores de niños hasta 3 años acerca de las nuevas tecnologías en la rutina doméstica y escolar, como también proponer un espacio de escucha, psicoeducación y reflexión. La práctica ocurrió en una escuela infantil en la región metropolitana de Porto Alegre, RS, Brasil, usando la modalidad de conversaciones grupales. La intervención permitió a los padres y profesores reflexionar un tema que repercute en la salud mental de los niños y en las relaciones entre los bebés y sus cuidadores.

Abstract Introduction: This paper aims to examine the psychometric properties, i.e., validity, reliability, factorial invariance, and latent mean differences based on gender, of the Perfectionistic Self-Presentation Scale, PSPS, in the Ecuadorian context. Method: A sample consisting of 597 Ecuadorian undergraduates participated in the study. Results: Confirmatory Factor Analysis supported a 14-item and three-dimensional model of the scale: Perfectionistic Self-Promotion, Nondisplay of Imperfection, and Nondisclosure of Imperfection. This model presented configural; measurement, i.e., metric, strong, and strict; as well as structural invariance across genders. Discriminant validity was observed by analysing correlations between PSPS factors and perfectionism traits. Males exhibited higher latent means of Perfectionistic Self-Promotion and also Nondisplay of Imperfection than females. Conclusions: The Spanish-translated and brief version of the PSPS represents a reliable and valid tool for assessing perfectionistic self-presentation in Ecuador.

Resumen Introducción: Este artículo tiene como objetivo examinar las propiedades psicométricas, i.e., validez, fiabilidad, invarianza factorial y diferencias de medias latentes en función del género, de la Escala de Autopresentación Perfeccionista, PSPS, en el contexto de Ecuador. Método: La muestra se compuso de 597 universitarios ecuatorianos. Resultados: El análisis factorial confirmatorio apoyó una estructura de la escala compuesta por 14 ítems y tres dimensiones: autopromoción perfeccionista, no-divulgación de la imperfección, y no-verbalización de la imperfección. Este modelo mostró invarianza configural; de medida, métrica, escalar y estricta; y estructural a través del género. El análisis de correlaciones entre los factores de la PSPS y los rasgos perfeccionistas evidenció la validez discriminante de la escala. Los hombres obtuvieron medias latentes significativamente más altas en comparación con las mujeres en los factores autopromoción perfeccionista y no-divulgación de la imperfección. Conclusiones: La versión de la PSPS abreviada y traducida al español representa una medida fiable y válida para evaluar la autopresentación perfeccionista en Ecuador.

RESUMEN

Web 2.0 is characterized by the development of the Internet from its initial static content to a dynamic and participatory content, and by the large place taken by social networks. The growing interest of health actors for information and communication via these new media is gradually but lastingly modifying the practice of nephrology. These developments require nephrologists to understand the issues, rules and risks associated with these digital tools. The present article summarizes the main practical aspects of communication with patients and health professionals and addresses the important issue of the digital identity of the caregiver in the new field of connected nephrology.

RESUMEN

Introducción: las úlceras vasculares son lesiones que se desarrollan principalmente en miembros inferiores, se acompañan de dolor continuo e incapacitante, dificultan la movilidad, alteran la propia imagen corporal y pueden interferir en las actividades de la vida diaria. Las úlceras venosas son graves, ocasionadas por insuficiencia venosa crónica e hipertensión venosa permanente, y la persona que las padece debe recibir cuidados de enfermería integrales, que contribuyan al autocuidado. Objetivo:describir las estrategias que debe tener en cuenta el profesional de enfermería para la promoción del autocuidado en personas con úlceras vasculares venosas. Metodología: revisión integrativa de la literatura. Se realizó búsqueda en bases de datos y recursos electrónicos: Medline a través de PubMed Health, Epistemonikos y SciELO. Se incluyeron artículos de investigación y de revisión relacionados con el problema en estudio, publicados en inglés, portugués o español en el periodo 2010-2020. Estudio sin riesgo, se respetan los derechos de autor. Resultados: se analizó una muestra constituida por 41 publicaciones. Los temas principales producto del análisis fueron: proceso de atención de enfermería y autocuidado, familiarizándose con la úlcera venosa y las opciones terapéuticas, conocimiento de la terapia de compresión, práctica de los estilos de vida saludables. Conclusiones: el cuidado de enfermería al paciente con úlcera venosa debe comenzar por reconocer a la persona desde una perspectiva holística y en reciprocidad con su entorno, lo que implica un proceso de atención integral que va más allá de la úlcera y valora al paciente como un sujeto activo en el cuidado, para que se familiarice con su herida y esté en capacidad de detectar señales de mejoría o de alarma, así como de conocer la terapia de compresión y opciones terapéuticas y de llevar a su cotidianidad la práctica de estilos de vida saludables

Introduction: Venous ulcers are lesions developed mainly on the lower limbs. They cause continuous and disabling pain, impair mobility, alter self-image, and interfere with daily life activities. Venous ulcers are serious. They are caused by chronic venous insufficiency and permanent venous hypertension. People suffering from venous ulcers should receive comprehensive nursing care that contributes to self-care. Objective: To describe the strategies nursing professionals should consider for promoting self-care in people with venous ulcers. Method: Integrative review of the literature. Databases and electronic resources were searched: Medline using PubMed, Health, Epistemonikos, and SciELO. Research and review articles related to the study problem, published in English, Portuguese, or Spanish between 2010 and 2020, were included. This is a risk-free study, and copyrights were respected. Results: A sample of 41 publications was analyzed. The main themes derived from the analysis were the nursing care process and self-care, getting familiar with venous ulcers and therapeutic options, knowledge of compression therapy, and practice of healthy lifestyles. Conclusions: Nursing care for patients with venous ulcers should begin by recognizing a person from a holistic perspective and reciprocally with their environment. This approach implies a comprehensive care process that goes beyond the ulcer and values patients as active subjects of care so that they become familiar with their wounds and detect signs of improvement or warning. They can also know about compression therapy and therapeutic options and take the practice of healthy lifestyles into their daily lives.

Metodologia: Revisão integrativa da literatura. Realizou-se busca nas bases de dados e recursos eletrônicos: Medline por meio do PubMed Health, Epistemonikos SciELO. Foram incluídos artigos de pesquisa e revisão relacionados ao problema em estudo, publicados em inglês, português ou espanhol, no período 2010-2020. Estudo sem risco, os direitos autorais são respeitados. Resultados: Foi analisada uma amostra de 41 publicações. Os principais tópicos resultantes da análise foram: processo de atenção de enfermagem e autocuidado, familiarização com a úlcera venosa e as opções terapêuticas, conhecimento da terapia compressiva, prática de estilos de vida saudáveis. Conclusões: O cuidado de enfermagem ao paciente com úlcera venosa deve começar por reconhecer à pessoa desde uma perspectiva holística e em reciprocidade com seu meio, o que implica um processo de atendimento integral que vai além da úlcera e valoriza ao paciente como sujeito ativo no cuidado para que ele se familiarize com sua ferida e seja capaz de detectar sinais de melhora ou alarme, bem como aprender sobre terapia compressiva e as opções terapêuticas e praticar estilos de vida saudáveis em sua vida diária.

RESUMEN

This study explored how a subsection of Canadians perceive older adults' vaccines through a qualitative analysis of comments posted in response to national online news articles. We used reflexive thematic analysis to analyse 147 comments from 31 news article comments sections published between 2015 and 2020 from five different national online news sources (CBC, National Post, Global News, Globe & Mail, and Huffington Post Canada) that focused on three older adults' diseases and vaccines: influenza, pneumococcal pneumonia, and herpes-zoster. Three themes encompassed the similarities and differences in how these three diseases were discussed: (1) the importance of personal experiences on stated stance in vaccine uptake or refusal, (2) questioning vaccine research and recommendations, and (3) criticisms of the government's unequal vaccine opportunities across different Canadian provinces. Our findings identified that perceptions regarding older adult vaccination were dependent on the vaccine type, and, therefore, we make suggestions for future researchers to build on our findings, particularly the need not to treat the research subject of "older adults' vaccines" as one entity. Gaining a better understanding of how older adults' vaccines are perceived in Canada will enable public health professionals to develop effective communication strategies that should ultimately improve vaccination rates for older adults.

RESUMEN

INTRODUCTION: Contraceptive prevalence is low in Mali. The information provided by the media men can help to increase or decrease the use of contraceptive methods. OBJECTIVE: To study the knowledge, attitudes and practices of Bamako media Men on family planning. MATERIAL AND METHODS: We carried out a descriptive cross-sectional study with prospective data collection from June 1 to August 30, 2019. It concerned journalists and presenters of 15 radio and 6 televisions in Bamako. RESULTS: During the 3 months, 615 media Men agreed to participate in this study. These are men and women from 36 to 45 years old in 37.2% of cases, married in 81.3% of cases. The radio with 85.5% was their main source of information on family planning. They all knew at least one contraceptive method. The best-known methods were pills (94.3%), injectables (57%) and implants (49.1%). They were in favor of the practice of family planning in 77.2% of cases, 76.9% had already used a method and 56.7% had already hosted a program on family planning. CONCLUSION: Media men are essential in the transmission of information. The quality of the information provided by these Media men can be influenced by their personal perceptions and attitudes. Their better involvement in the promotion of family planning can help to increase contraceptive prevalence.

INTRODUCTION: La prévalence contraceptive est faible au Mali. Les informations transmises par les Hommes de médias peuvent contribuer à augmenter ou à diminuer l'utilisation des méthodes contraceptives. OBJECTIF: Etudier les connaissances, attitudes et pratiques des Hommes de médias de Bamako sur la planification familiale. MATÉRIEL ET MÉTHODES: Nous avons réalisé une étude transversale descriptive avec collecte prospective des données du 1er juin au 30 août 2019. Elle a concerné les journalistes et les animateurs de 15 radios et 6 télévisions de Bamako. RÉSULTATS: Durant les 3 mois, 615 Hommes de médias de Bamako ont accepté de participer à cette étude. Il s'agissait d'hommes et de femmes âgés de 36 à 45 ans dans 37,2% des cas, mariés dans 81,3% des cas. La radio avec 85,5% était leur principale source d'information sur la planification familiale. Ils connaissaient tous au moins une méthode contraceptive. Les méthodes les plus connues étaient les pilules (94,3%), les injectables (57%) et les implants (49,1%). Ils étaient favorables à la pratique de la planification familiale dans 77,2% des cas, 76,9% avaient déjà utilisé une méthode et 56,7% avaient déjà animé une émission sur la planification familiale. CONCLUSION: Les Hommes de médias sont essentiels dans la transmission de l'information. La qualité de l'information fournie par ces Hommes de médias peut être influencée par leurs perceptions et attitudes personnelles. Leur meilleure implication dans la promotion de la planification familiale peut contribuer à augmenter la prévalence contraceptive.

RESUMEN

Resumo A análise integrada da morfologia urbana e das características funcionais permite uma melhor compreensão da estrutura e da dinâmica intraurbana das cidades médias, indicando uma série de elementos que demonstram associações entre o espaço intraurbano e a intensidade e qualidade do relacionamento de uma determinada centralidade com o seu entorno. Com base no estudo de caso de Montes Claros, Minas Gerais, apresentamos uma proposta metodológica de avaliação de aspectos morfológicos e funcionais de cidades médias, utilizando como principal fonte de dados o Censo Demográfico em conjunto com outras informações geoespaciais livres (i.e., modelo digital de terreno e imagens de satélite). Identificamos a distribuição espacial dos tipos de ocupação, isto é, a densidade de edificações dos tipos domicílio, comércio e serviços e em construção. Ademais, quantificamos e avaliamos as características (renda e estrutura etária) dos vetores de expansão de Monte Claros. Nesse município, identificamos a formação de centralidades intraurbanas menos desenvolvidas em relação a outros polos de desenvolvimento de Minas Gerais (Juiz de Fora, Uberlândia, Pouso Alegre, dentre outros). Na cidade, a concentração das funções em duas centralidades (centro principal e subcentro de maior destaque) amplia a segregação socioespacial, diante da ausência de centralidades importantes nas proximidades das áreas de maior crescimento periférico entre 2000 e 2010.

Abstract Integrated analysis of urban morphology and functional characteristics allows for a better understanding of the structure and intra-urban dynamics of intermediate cities, indicating a series of elements that demonstrate associations between intra-urban space and the intensity and quality of the relationship of a given centrality with its surroundings. Based on the case study of Montes Claros, Minas Gerais, we present a methodological proposal for evaluating morphological and functional aspects of intermediate cities using information from the Demographic Census and other free geospatial datasets (i.e. digital terrain model and satellite images). We identified the spatial distribution of the types of occupation, such as (a) density of residential type buildings, (b) trade and services and (c) under construction. Furthermore, we quantified and evaluated the characteristics (income and age structure) of the expansion vectors of Montes Claros. In Montes Claros, we identified the formation of less developed intra-urban centralities compared to other development hubs in Minas Gerais (Juiz de Fora, Uberlândia, Pouso Alegre, among others). In the city, the concentration of functions in two centralities (the main center and the most prominent subcenter) increases socio-spatial segregation, given the absence of important centralities close to areas with the greatest peripheral growth between 2000 and 2010.

Resumen El análisis integrado de la morfología urbana y las características funcionales permite una mejor comprensión de la estructura y dinámica intraurbana de las ciudades intermedias, indicando una serie de elementos que demuestran asociaciones entre el espacio intraurbano y la intensidad y calidad de una determinada centralidad con su entorno. Con base en el estudio de caso de Montes Claros, Minas Gerais, presentamos una propuesta metodológica para evaluar aspectos morfológicos y funcionales de ciudades intermedias utilizando como fuente principal de información del censo demográfico y otra información geoespacial gratuita (es decir, modelo digital del terreno e imágenes de satélite). Identificamos la distribución espacial de los tipos de ocupación, como 1) densidad de edificaciones de tipo residencial; 2) comercio y servicios, y 3) en construcción. Además, cuantificamos y evaluamos las características (estructura de ingresos y edades) de los vectores de expansión de Monte Claros. En Montes Claros, identificamos la formación de centralidades intraurbanas menos desarrolladas en comparación con otros polos de desarrollo en Minas Gerais (Juiz de Fora, Uberlândia, Pouso Alegre, entre otros). En la ciudad, la concentración de funciones en dos centralidades (el centro principal y el subcentro más destacado) incrementa la segregación socioespacial, dada la ausencia de centralidades importantes cercanas a las áreas de mayor crecimiento periférico entre 2000 y 2010.
