ABSTRACT
ABSTRACT Introduction: Contrast-associated acute kidney injury (CA-AKI) is a deterioration of kidney function that occurs after the administration of a iodinated contrast medium (ICM). Most studies that defined this phenomenon used older ICMs that were more prone of causing CA-AKI. In the past decade, several articles questioned the true incidence of CA-AKI. However, there is still a paucity of a data about the safety of newer ICM. Objective: To assess the incidence of CA-AKI in hospitalized patients that were exposed to computed tomography (CT) with and without ICM. Methods: Prospective cohort study with 1003 patients who underwent CT in a tertiary hospital from December 2020 through March 2021. All inpatients aged > 18 years who had a CT scan during this period were screened for the study. CA-AKI was defined as a relative increase of serum creatinine of ≥ 50% from baseline or an absolute increase of ≥ 0.3 mg/dL within 18 to 48 hours after the CT. Chi-squared test, Kruskal-Wallis test, and linear regression model with restricted cubic splines were used for statistical analyses. Results: The incidence of CA-AKI was 10.1% in the ICM-exposed group and 12.4% in the control group when using the absolute increase criterion. The creatinine variation from baseline was not significantly different between groups. After adjusting for baseline factors, contrast use did not correlate with worse renal function. Conclusion: The rate of CA-AKI is very low, if present at all, with newer ICMs, and excessive caution regarding contrast use is probably unwarranted.
RESUMO Introdução: Lesão renal aguda associada ao contraste (LRA-AC) é uma deterioração da função renal que ocorre após a administração de meio de contraste iodado (MCI). A maioria dos estudos que definiram esse fenômeno utilizaram MCI mais antigos, mais propensos a causar LRA-AC. Na última década, diversos artigos questionaram a verdadeira incidência de LRA-AC. Entretanto, ainda há escassez de dados sobre a segurança dos MCI mais novos. Objetivo: Avaliar a incidência de LRA-AC em pacientes hospitalizados expostos à tomografia computadorizada (TC) com e sem MCI. Métodos: Estudo de coorte prospectivo com 1.003 pacientes submetidos a TC em hospital terciário, de dezembro/2020 a março/2021. Todos os pacientes internados com idade ≥ 18 anos que realizaram TC nesse período foram selecionados. A LRA-AC foi definida como aumento relativo de creatinina sérica de ≥ 50% em relação ao valor basal ou aumento absoluto de ≥ 0,3 mg/dL dentro de 18 a 48 horas após a TC. Utilizamos o teste qui-quadrado, teste de Kruskal-Wallis e modelo de regressão linear com splines cúbicos restritos para análises estatísticas. Resultados: A incidência de LRA-AC foi 10,1% no grupo exposto ao MCI e 12,4% no grupo controle ao usar o critério de aumento absoluto. A variação da creatinina em relação ao valor basal não foi significativamente diferente entre os grupos. Após ajuste para fatores basais, o uso de contraste não se correlacionou com pior função renal. Conclusão: A taxa de LRA-AC é muito baixa, caso exista, com MCIs mais novos, e a cautela excessiva quanto ao uso de contraste provavelmente não se justifica.
ABSTRACT
The previous moral injury theory implied the premise of taking individual as the research object, while there were few studies on collective moral injury. Collective moral injury is defined as a series of consequences of violating widely accepted moral beliefs rather than simply adding up symptoms of injured individuals within a group. From the America "Floyd Case", this paper analyzed the functional elements and generating mechanism of collective moral injury, that was, the diversification of trauma sources events could appear alone or interweave, collective moral resilience showed the characteristics of social integrity and time accumulation, the interaction between collective trauma sources and collective moral resilience determined whether collective moral injury occurs. As the We-Media become popular, collective feature of moral injury is more evident, which presents two new features that the Internet platform becomes a hub for trauma events and the information Internet recorded consolidates collective moral resilience. To deal with collective moral injury, it was needed to respond to social concerns and guidance moral public opinion, respect the original endogenous order and inherit the traditional culture, satisfy reasonable moral needs and enlighten moral sense of people as well.
ABSTRACT
As an important part of China’s excellent traditional culture, Traditional Chinese Medicine (TCM) culture contains rich philosophical thoughts and has made important contributions to human health. The advent of the all media era has provided an opportunity for the full effect communication of TCM culture. On the basis of clarifying the scientific connotation of all media, this paper analyzed the dilemma faced by the all media communication of TCM culture under the background of the epidemic, and explored the all media communication path of TCM culture from four aspects: new ecology of content, new system of technology, new model of management, and new targeting of audience, so as to improve the communication, guidance, influence and credibility of the all media of TCM culture.
ABSTRACT
Ocular hypertension(OH)can cause a variety of ocular structural and functional damage, among which the effect on ocular refraction has long been recognized in the clinic. The effect of OH on ocular refraction is related to the transparency and shape of refractive media, as well as the changes of the axial length. Due to the different speed and degree of intraocular pressure(IOP)elevation, the changes of refraction are reversible or irreversible. Irreversible changes in refraction are often accompanied by visual transmission impairment, and have a certain reference value for the evaluation of the latter condition. IOP changes lead to changes in the axial length, which are related to scleral remodeling and choroidal perfusion changes, and have a certain impact on the development of myopia and refractive error after cataract surgery. In this paper, the research progress of the changes of refractive media and axial length caused by OH, as well as the characteristics of the effects on ocular refraction are summarized, hoping to deepen the understanding of the effect of OH on ocular refraction, and provide reference for preventing irreversible ocular refractive changes, guiding the assessment of visual transmission damage and preventing or controlling the development of axial myopia.
ABSTRACT
@#Background: Orthorexia nervosa (ON) is an eating disorder characterized by an obsession with eating healthy foods, which has physical, psychological, and social impacts. The use of social media platform such as Instagram is suspected to be one of the risk factors of ON, as health information on Instagram can reach thousands of people despite the fact that its source is frequently unreliable. Objective: To determine the correlation between the intensity of Instagram usage and ON among Universitas Gadjah Mada (UGM) students, as well as the correlation between confounding variables (gender, monthly income, age, faculty cluster, and nutritional knowledge) and ON. Methods: The research design used is an observational study with cross-sectional design that involved 529 students. Samples were taken by stratified random sampling, and data was collected online. Chi square test with ꭤ = 0.05 was used in this study. Results: The results showed that as many as 55% of students were diagnosed with ON and most of the students had moderate intensity of using Instagram. There is a correlation between the intensity of using social media Instagram and ON in UGM students (p value = 0.037<0.05) and there is no correlation of confounding variables (gender, monthly income, age, faculty cluster, and nutritional knowledge) with ON. Conclusion: There is a positive correlation between the intensity of Instagram use and ON in UGM students, and no confounding variables were found in this study. Keywords: Orthorexia Nervosa, Instagram, Social Media, Eating Disorders
ABSTRACT
Abstract Objectives To assess the hearing thresholds in acute otitis media, otitis media with effusion and chronic otitis media (non-suppurative, non-cholesteatomatous suppurative and cholesteatomatous) and to compare the hearing outcomes with non-diseased ears (in bilateral cases) or contralateral healthy ears (in unilateral cases), since hearing loss is the most frequent sequel of otitis media and there is no previous study comparing the audiometric thresholds among the different forms of otitis media. Methods Cross sectional, controlled study. We performed conventional audiometry (500-8000 Hz) and tympanometry in patients with otitis media and healthy individuals (control group). Hearing loss was considered when the hearing thresholds were > 25 dBHL. Results Of the 112 patients diagnosed with otitis media (151 ears), 48 were men (42.86%) and 64 were women (57.14%). The average age was 42.72 years. Of those, 25 (22.32%) were diagnosed as AOM, 15 (13.39%) were diagnosed with OME and the remaining 72 (63.28%) were diagnosed with COM (non-suppurative COM, n = 31; suppurative COM, n = 18; cholesteatomatous COM, n = 23). As compared with controls, all forms of otitis media had significantly higher bone-conduction thresholds (500-4000 Hz). Conductive hearing loss was the most frequent type of hearing loss (58.94%). However, the number of patients with mixed hearing loss was also relevant (39.07%). We noted that the presence of sensorioneural component occurred more frequently in 1) Higher frequencies; and 2) In groups of otitis media that were more active or severe in the inflammatory/infective standpoint (AOM, suppurative COM and cholesteatomatous COM). Conclusion All types of otitis media, even those with infrequent episodes of inflammation and otorrhea, had worse bone conduction thresholds as compared with nondiseased ears (p < 0.01). We observed worse hearing outcomes in ears with recurrent episodes of otorrhea and in ears with AOM, especially in high frequencies.
ABSTRACT
ABSTRACT Objective: To report on the experience and impressions of the Brazilian orthopedic trauma surgeons attending the Leadership Development Program (LDP) hosted by the Sociedade Brasileira do Trauma Ortopédico (SBTO) in Sao Paulo, Brazil on November 4, 2022. Methods: Forty-eight orthopedic trauma surgeons from five different regions throughout Brazil were provided a link to complete The Big Five Test, a validated online personality assessment. The questionnaire was available in Portuguese and was intended to provide a background on individual personality traits and their influence on interpersonal interactions. The LDP integrated content from literature reviews specific to Latin America, established leadership programs from leading business schools, and various subject matter experts. Prior to the start of the LDP, participants received a pre-course survey evaluating demographic information, a needs assessment, and the prioritization of leadership topics utilizing a 5-point Likert-scale. Attendees participated in the one-day, interactive LDP focusing on the fundamental principles of leadership development, communication, personal development, emotional intelligence and negotiation. Following the LDP, a post-course evaluation was administered to determine the participants' overall experience, and suggestions for LDP improvement. Results: Forty-one of the forty-eight course participants completed the pre-course evaluation, whereas forty-six of the forty-eight participants completed the post-course evaluations. Overwhelmingly, the lack of opportunity was most prevalently reported as the main obstacle to attending a leadership course, as cited by 56% of respondents. Conclusion: Expanding the accessibility, diversity, and customizability of leadership programs can facilitate the development of personal tools needed to move healthcare forward. Critical topics include emotional intelligence and other differentiating leadership qualities that distinguish true transformational and servant leaders. Advancing leadership skills can stimulate networking, expose learners to experiential learning styles, inspire others to create positive change, and engender creative solutions for systematic improvements and health outcomes.

ABSTRACT
A fim de conhecer o tempo e a frequência com que idosos se expõem a notícias e informações sobre a COVID-19 por diferentes mídias e relacioná-los com sintomas depressivos e de ansiedade, 154 idosos (M = 69,06) do Distrito Federal responderam a um questionário online. A amostra foi composta majoritariamente por mulheres, brancas, escolarizadas e com renda proveniente de aposentadoria e/ou pensão. Constatou-se que a televisão foi o meio de comunicação mais utilizado pelos participantes, seguido pelas redes sociais. Ao considerar características demográficas, idosos mais jovens (60 a 74 anos) e com ensino superior completo apresentaram maior exposição a notícias por meio das redes sociais do que os mais velhos e com menor escolaridade. Idosos com rastreio para depressão e transtorno de ansiedade generalizada permaneceram mais horas expostos a informações sobre a COVID-19 veiculadas pela televisão que idosos não rastreados. Além disso, aqueles com rastreio para depressão relataram maior frequência de exposição a esse conteúdo pela televisão e pelas redes sociais. Os resultados deste estudo revelam a necessidade de planejamento de medidas de promoção e prevenção em saúde específicas para a população idosa a fim de lidar com as consequências da pandemia e, especialmente, infodemia de COVID-19.
Para conocer el tiempo y la frecuencia con que los ancianos están expuestos a noticias e informaciones sobre el COVID-19 por diferentes medios de comunicación y relacionarlos con los síntomas depresivos y de ansiedad, 154 ancianos (m = 69,06) del Distrito Federal respondieron a un cuestionario online. La muestra estaba compuesta mayoritariamente por mujeres, de raza blanca, con estudios y con ingresos por jubilación y/o pensión. Se comprobó que la televisión era el medio de comunicación más utilizado por los participantes, seguido de las redes sociales. Teniendo en cuenta las características demográficas, los más jóvenes (60 a 74 años) y con estudios superiores completos presentan una mayor exposición a las noticias a través de las redes sociales que los más mayores y con menor escolaridad. Los ancianos con cribado de depresión y trastorno de ansiedad generalizada permanecieron más horas expuestos a la información sobre COVID-19 emitida por televisión que los ancianos no cribados. Además, los que se sometieron a pruebas de detección de la depresión informaron de una mayor frecuencia de exposición a este contenido por parte de la televisión y los medios sociales. Los resultados de este estudio revelan la necesidad de planificar medidas de promoción de la salud y de prevención específicas para la población de edad avanzada con el fin de hacer frente a las consecuencias de la pandemia y, especialmente, de la infodemia de COVID-19.
In order to know the time and frequency with which elderly are exposed to news and information about COVID-19 through different media and relate them with depressive and anxiety symptoms, 154 elderly (M = 69.06) from Distrito Federal answered an online questionnaire. The sample was composed mostly of women, white, educated, and with income from retirement and/or pension. It was found that television was the media most used by participants, followed by social networks. Considering demographic characteristics, younger elders (60 to 74 years old) and with complete college education had more exposure to news through social networks than the older ones and with less education. Elderly with screening for depression and generalized anxiety disorder remained exposed more hours to information about COVID-19 broadcast on television than unscreened elderly. In addition, those with screening for depression reported greater frequency of exposure to this content on television and social media. The results of this study reveal the need for health promotion and prevention measures planning specific to the elderly population to deal with the consequences of the pandemic and especially infodemic of COVID-19.
ABSTRACT
Resumo A partir do cenário brasileiro, marcado por diferentes expressões da violência, são construídas práticas midiáticas que representam a juventude pauperizada de forma a criminalizar tal grupo. Este artigo apresenta uma discussão a respeito dos sentidos produzidos por jovens de 14 a 16 anos sobre as representações midiáticas expressas por setores da mídia hegemônica. Trata-se de uma pesquisa participante, delineada a partir da perspectiva do sociólogo Orlando Fals-Borda e da ideia de coautoria de Mikhail Bakhtin. A pesquisa foi realizada em uma cidade do estado de Minas Gerais, e foram construídos sete grupos de discussão, em que reportagens nas quais jovens são associados a episódios tidos como criminosos foram discutidas. Por meio dos diálogos construídos, foi possível identificar que o conteúdo midiático pode resultar em uma série de violências nas vidas desses jovens, que resistem através da busca por estratégias criativas, envolvendo a arte e mídias alternativas.
Abstract From a scenario marked by different expressions of violence emerge media practices set on criminalizing impoverished youth. This article examines the meanings produced by youth aged 14 to 16 years about the media representations broadcasted by hegemonic sectors. A participative research designed based on sociologist Orlando Fals-Borda's work and Mikhail Bakhtin's co-authorship was conducted with youth from the state of Minas Gerais. Seven discussion groups were created to debate the association between youth and criminal activity on the news. Analysis of the dialogues showed that media content can impart a series of violence in their lives. However, they resist through creative strategies involving art and alternative media.
Résumé A partir d'un scénario marqué par différentes expressions de la violence ressortent des pratiques médiatiques visant à criminaliser la jeunesse appauvrie. Cet article discute les significations produits par des jeunes de 14 à 16 ans à propos des représentations médiatiques formulées par les secteurs hégémoniques. Une recherche intervenante, esquissée d'après la perspective du sociologue Orlando Fals-Borda et du concept de cocréation de Mikhail Bakhtin, a été réalisée dans une ville de l'État du Minas Gerais. Sept groupes de discussion ont été créé pour débattre des reportages où des jeunes sont associés à des épisodes criminels. L'analyse des dialogues a montré que le contenu des médias peut mener à une série de violences dans leur vie. Pourtant, ils résistent grâce à des stratégies créatives faisant appel à l'art et aux médias alternatifs.
Resumen A partir del escenario brasileño, marcado por diferentes expresiones de violencia, se construyen prácticas mediáticas, para criminalizar a la juventude más pobre. Este artículo discute los sentidos producidos por jóvenes de 14 a 16 años respecto a las representaciones mediáticas, expressadas por sectores de los medios hegemónicos. Se trata de una investigação participante, diseñada a partir de la perspectiva del sociólogo Orlando Fals-Borda y la idea de coautoría de Mikhail Bakhtin. La investigación fue realizada en una ciudad del estado de Minas Gerais, mediante siete grupos de discusión, donde se analizaron las asociaciones que hacen de los jóvenes con episodios delictivos. A partir de los diálogos establecidos, se encontró que lo proyectado por los medios de comuncación puede resultar de considerables violencias en la vida de aquellos jóvenes, quienes se resisten a través de la búsqueda de estrategias creativas como el arte y medios alternativos.

ABSTRACT OBJECTIVE Assess the correlation between the sales of two drugs with no proven efficacy against covid-19, ivermectin and chloroquine, and other relevant variables, such as Google® searches, number of tweets related to these drugs, number of cases and deaths resulting from covid-19. METHODS The methodology adopted in this study has four stages: data collection, data processing, exploratory data analysis, and correlation analysis. Spearman's method was used to obtain cross-correlations between each pair of variables. RESULTS The results show similar behaviors between variables. Peaks occurred in the same or near periods. The exploratory data analysis showed shortage of chloroquine in the period corresponding to the beginning of advertising for the application of these drugs against covid-19. Both drugs showed a high and statistically significant correlation with the other variables. Also, some of them showed a higher correlation with drug sales when we employed a one-month lag. In the case of chloroquine, this was observed for the number of deaths. In the case of ivermectin, this was observed for the number of tweets, cases, and deaths. CONCLUSIONS The results contribute to decision making in crisis management by governments, industries, and stores. In times of crisis, as observed during the covid-19 pandemic, some variables can help sales forecasting, especially Google® and tweets, which provide a real-time analysis of the situation. Monitoring social media platforms and search engines would allow the determination of drug use by the population and better prediction of potential peaks in the demand for these drugs.
RESUMO OBJETIVO Investigar a correlação entre as vendas de dois medicamentos sem eficácia comprovada no tratamento de covid-19, ivermectina e cloroquina, e outras variáveis relevantes: pesquisas no Google®, número de tweets relacionados aos medicamentos, casos e óbitos decorrentes da covid-19. MÉTODOS A metodologia adotada neste estudo se divide em quatro partes: coleta de dados; processamento dos dados; análise exploratória; e análise de correlação. Foi utilizado o método de Spearman para obter as correlações cruzadas entre cada par de variáveis. RESULTADOS Os resultados mostram similaridade entre os comportamentos das variáveis. Os picos ocorreram em períodos iguais ou próximos. A análise exploratória dos dados apontou que houve falta de cloroquina no período correspondente ao início das divulgações sobre a aplicação desses medicamentos para o tratamento da covid-19. Ambos os medicamentos apresentaram correlação alta e estatisticamente significativa com as demais variáveis analisadas. Também foi observado que algumas delas apresentaram maior correlação com as vendas de medicamentos quando assumiram defasagem temporal de um mês. No caso da cloroquina, isso ocorreu com a variável óbitos. No caso da ivermectina, ocorreu com as variáveis número de tweets, casos e óbitos. CONCLUSÕES Os resultados observados contribuem para a tomada de decisão durante a gestão de crises por parte de governo, indústrias e comércios. Em momentos de crises, como observado durante a pandemia, as variáveis mostraram que são capazes de auxiliar na previsão de vendas, em especial o Google® e os tweets, que proporcionam uma análise em tempo real da situação. Acompanhar as redes sociais e mecanismos de busca permitiria detecção de uso pela população e melhor previsão de potenciais picos de demanda desses medicamentos.

ABSTRACT Purpose: This study aimed to assess and interpret how vitreoretinal surgeons use surgical videos available on social media as complementary learning tools to improve, review, or update their abilities, considering their different levels of expertise. Methods: In this cross-sectional survey, an online survey was sent to vitreoretinal specialists and fellows. Results: This survey included 258 participants, of whom 53.88% had been in practice for >10 years (senior surgeons), 29.07% between 4 and 10 years (young surgeons), and 17.05% for <3 years (surgeons in training). Retinal surgical videos available on social media were used by 98.84% of the participants (95% confidence interval, 97.52%-100%). YouTube (91%) was the most common source of videos, and surgeons in training watched more videos on YouTube than senior surgeons. Regarding the preferred method when preparing for a procedure, 49.80% of the participants watched surgical videos available on social media, 26.27% preferred to "consult colleagues", and 18.82% preferred to seek information in scientific articles. Participants valued the most the "image quality" (88%) and presence of "surgical tips and tricks" (85%). Conclusion: Surgical videos can provide benefits in acquiring strategic skills, such as decision-making, surgical planning, and situational awareness. Retina surgeons used them as teaching aids regardless of their level of expertise, despite being relatively more valuable to surgeons in training or young surgeons.
RESUMO Objetivo: Avaliar e interpretar como os cirurgiões vitreorretinianos utilizam os vídeos cirúrgicos disponíveis nas mídias sociais como ferramentas complementares de aprendizagem para melhorar, revisar ou atualizar suas habilidades, considerando seus diferentes níveis de especialização. Métodos: Nesta pesquisa transversal, um survey online foi enviado à especialistas e aprendizes na área vítreo-retiniana. Resultados: Esta pesquisa incluiu 258 participantes, dos quais 53,88% atuavam há mais de 10 anos (cirurgiões seniores), 29,07% entre 4 e 10 anos (cirurgiões jovens) e 17,05% há menos de 3 anos (cirurgiões em treinamento). Vídeos cirúrgicos de retina nas mídias sociais foram usados por 98,84% dos participantes (intervalo de confiança de 95%, 97,52%-100%). A fonte mais comum de acesso aos vídeos foi o YouTube (91%), e o grupo de cirurgiões com menos de 3 anos de experiência assistiu mais vídeos no YouTube em comparação aos cirurgiões seniores. Assistir a vídeos cirúrgicos nas redes sociais foi o método preferido na preparação para um procedimento para 49,80% dos participantes versus 26,27% que preferiram "consultar colegas" e 18,82% que preferiram buscar informações em artigos científicos. A "qualidade de imagem" (88%) e a presença de "dicas e truques cirúrgicos" (85%) foram as características dos vídeos mais valorizadas pelos participantes. Conclusão: O uso de vídeos cirúrgicos pode trazer benefícios na aquisição de habilidades estratégicas, como tomada de decisão, planejamento cirúrgico e consciência situacional. Sua aplicação como auxiliar de ensino foi utilizada por cirurgiões de retina independentemente de seu nível de especialização, apesar de ser relativamente mais valioso para cirurgiões em formação ou com menos de 10 anos de experiência.
ABSTRACT
Objective: To explore the social and clinical factors that predict audiometric outcomes in patients undergoing ossicular chain reconstruction. Methods: A retrospective analytical cohort study was conducted, including patients 18 years of age or older with a history of chronic otitis media (COM) and/or any of its complications, who underwent ossicular chain reconstruction with Partial Ossicular Replacement Prosthesis (PORP) or Total Ossicular Replacement Prosthesis (TORP), at Hospital San José and Hospital infantile Universitario de San José between 2012 and 2020. We excluded patients with ossicular chain malformations and those with incomplete information. Information about sociodemographic and clinical factors was collected. Additionally, the surgery findings information was analyzed using the Ossiculoplasty outcome parameter staging ( OOPS) index. Results: A total of 35 adult patients who underwent ossicular chain reconstruction were retrospectively studied. An improvement was evidenced in the Preoperative Pure-Tone Average (PTA) and postoperative PTA (p-value=0.036), as well as in the pre and postoperative air-bone gap (ABG) (p-value < 0.01). A moderate correlation coefficient was found between the OOPS index and the postoperative PTA (p= 0.429), and between the OOPS index and the postoperative (ABG) (p= 0.653). Conclusion: We found that a higher OOPS score is correlated with worse hearing outcomes postoperatively, and there was no association between the demographic or pathologic factors with a worse postoperative hearing outcome. Therefore, OOPS index can predict audiometric outcomes in patients undergoing ossicular chain reconstruction in a developing country, regardless of the demographic or pathologic factors.
Objetivo: Evaluar los factores sociales y clínicos que predicen los desenlaces audiométricos en pacientes llevados a reconstrucción de cadena osicular en un país envía de desarrollo. Métodos: Se realizo un estudio de cohorte analítico retrospectivo donde se incluyeron pacientes mayores de 18 años, con antecedente de otitis media crónica y/o alguna complicación/secuela de esta, que fueron llevados a reconstrucción de la cadena osicular con prótesis PORP - TORP de la Fundación Universitaria de Ciencias de la Salud entre el año 2012 y 2020, se excluyeron pacientes con malformaciones de la cadena osicular y aquellos con informacion incompleta de su historia clinica y quirurgica. Resultados: La población estudiada fue 35 pacientes, en los cuales se compararon variables demográficas, antecedentes de rinitis o tabaquismo activo, parámetros audiológicos pre y postoperatorios, y hallazgos intraquirurgicos. Se evidenció una diferencia estadísticamente significativa entre el promedio tonal auditivo (PTA) preoperatorio y el PTA postoperatorio (p-valor=0.036), así como en el gap aéreo- oseo pre y post operatorio ( p-valor < 0.01). Se reportó un coeficiente de correlación moderado entre el índice OOPS y el PTA post operatorio (p = 0.429), y entre el índice OOPS y el gap aéreo óseo post operatorio (p = 0.653), lo que indica que a mayor puntaje en el índice OOPS peores desenlaces auditivos. Conclusión: En este estudio un mayor puntaje en el índice OOPS se correlacionó con peores desenlaces auditivos. No se evidenció correlación entre los factores demográficos u otras comorbilidades descritas y un peor desenlace auditivo post operatorio. Aunque se obtuvo un GAO postoperatorio ≤20dB en el 48.5% de los pacientes, se observó una disminución en el GAO estadísticamente significativo.

Con el incremento en el acceso y uso de las redes sociales en Colombia, es de esperar que prácticas y discursos violentos se trasladen a estos espacios digitales. Sin duda, hoy en día las redes sociales son parte de los ecosistemas de información y comunicación de los colombianos en los que las culturas de violencia y paz se expanden y transforman. En este contexto, es esencial explorar las formas en las que investigamos la violencia en redes sociales, ya que entender este fenómeno permite responder mejor a las necesidades y experiencias de las comunidades del país. Este artículo busca explorar cómo se ha estudiado la violencia en las redes sociales en Colombia mediante una revisión sistemática de la literatura. Resultados muestran un complejo trayecto de investigación en el país que comprende variados objetivos, como entender las diferentes formas en las que la violencia es ejercida a través de redes sociales o sobre cómo nos permite conocer más contextos de violencia. Igualmente, los resultados muestran que las investigaciones están principalmente enfocadas en dos plataformas: Facebook y Twitter. Finalmente, se encontró que los artículos están principalmente orientados a investigar tres tipos de violencias: violencia de género, violencia relacionada con conflicto armado y violencia escolar. Los hallazgos de esta revisión sistemática de la literatura permiten, por un lado, valorar previos estudios que han demostrado el complejo panorama de la violencia mediática en el país y, por otro lado, descubrir posibles vacíos en la literatura que podrían ser respondidos por investigadoras e investigadores en el futuro.
With the increase in the access and use of social media platforms in Colombia, it is expected that violent practices and discourses transfer to these digital spaces. Certainly, today's social media are part of the information and communication ecosystems of Colombians, where cultures of violence expand and transform. In this context, it is essential to explore the ways in which we examine and research social media violence, since understanding this phenomenon allows us to strengthen a culture of peace that better responds to the needs and experiences of the country's communities. Thus, this article seeks to explore how social media violence has been studied in Colombia, through a systematic literature review. Results show a complex trajectory of research in the country that includes various objectives, such as understanding the different ways in which violence is exercised through social media, or how it allows us to learn more about contexts of violence. Likewise, the results show that research is mainly focused on two platforms: Facebook and Twitter. Finally, the articles were found to be mainly focused on three types of violence: gender-based violence, violence related to armed conflict, and school violence. Overall, findings of this systematic literature review allow, on the one hand, to assess previous studies that have demonstrated the complex landscape of social media violence in the country, and, on the other hand, to discover possible gaps in the literature that could be addressed by researchers in the future.
ABSTRACT
La neurorretinopatía macular aguda es una condición rara con patogenia microvascular. Se presenta con un inicio agudo con escotomas paracentrales correspondientes a lesiones paramaculares evidentes. Los avances en las imágenes multimodales permitieron caracterizar este trastorno de retina y crear nuevos conceptos. Serraf, en el 2013, identificó dos formas por medio de la tomografía de coherencia óptica dominio espectral: el tipo 1 conocido como maculopatía paracentral aguda media en la cual se observa una banda hiperreflectiva en la capa nuclear interna, y el tipo 2 en el cual la banda hiperreflectiva se ubica en la capa nuclear externa, que involucra la zona elipsoide y la zona de interdigitación con el epitelio pigmentario de la retina. Hasta el momento no existe cura; pero se puede actuar sobre los factores de riesgo. Por ser una condición rara y por no existir reportes hasta el momento en Cuba es que se presentan a continuación dos pacientes con cuadros clínicos similares de estas dos variantes; concluyendo la importancia que presentan las imágenes multimodales como medio auxiliar diagnóstico.
Acute macular neuroretinopathy is a rare condition with complex pathogenesis and microvascular cause. It appears with acute onset, with paracentral scotomas corresponding to obvious paramacular lesions. Advances in multimodal imaging made it possible to characterize this retinal disorder and to create new concepts. Serraf, in 2013, identified two forms by spectral domain optical coherence tomography: type 1, known as paracentral acute middle maculopathy, in which a hyperreflective band is observed in the inner nuclear layer; and type 2, in which the hyperreflective band is located in the outer nuclear layer, involving the ellipsoid zone and the zone of interdigitation with the retinal pigment epithelium. Up to this moment, there is no cure; but it is possible to act on the risk factors. Because it is a rare condition and because there are no reports so far in Cuba, two patients with similar clinical pictures of these two variants are presented; concluding the importance of multimodal images as an auxiliary diagnostic tool.
ABSTRACT
Introducción: La infección por Streptococcus pneumoniae constituye una causa importante de morbimortalidad en el mundo, sobre todo en niños menores de 5 años, en los que ocasiona de 1 a 2 millones de muertes anuales. Objetivo: Determinar la presencia de S. pneumoniae en muestras clínicas obtenidas en niños. Métodos: Se realizó un estudio descriptivo y transversal en niños menores de 5 años de edad con diagnóstico clínico de enfermedad neumocócica invasiva, asistidos en dos hospitales pediátricos de Santiago de Cuba durante el periodo 2014-2018. De las 1466 muestras clínicas tomadas y procesadas, en 131 fue aislado el agente patógeno; estas correspondieron a 59 pacientes con formas clínicas de la infección y 72 portadores. Para el procesamiento estadístico de la información se utilizaron las frecuencias absoluta y relativa como medidas de resumen. Resultados: En general, la positividad por S. pneumoniae fue de 8,9 %, con mayores frecuencias de aislamiento en las muestras de líquido cefalorraquídeo (81,8 %), líquido pleural (47,1 %) y exudado ótico (21,9 %), que asimismo coincidieron con los porcentajes más elevados de neumonía (61,0), otitis media aguda (23,7) y meningitis (15,3), como formas clínicas de la enfermedad neumocócica, que aquejó principalmente a niños de 1 año de edad, seguidos de los mayores de 2 años. De igual modo, se identificaron 9 serotipos de S. pneumoniae, con predominio del 19A (39,0 %), el 14 (25,4 %) y el 6A (11,9 %). En los pacientes que portaban la bacteria en la nasofaringe se identificaron 8 tipos serológicos, predominantemente el 19A y el 14. Por último, se halló una alta resistencia microbiana a la eritromicina y a la combinación trimetoprima-sulfametoxazol. Conclusiones: Los resultados de este estudio proporcionaron un referente científico antes de la introducción de la vacuna antineumocócica cubana, lo que permitirá evaluar su impacto en la incidencia de dicha enfermedad.
Introduction: The infection due to Streptococcus pneumoniae constitutes an important cause of morbimortality in the world, mainly in children under 5 years, that causes from 1 to 2 million annual deaths. Objective: To determine the presence of S. pneumoniae in clinical samples obtained in children. Methods: A descriptive and cross-sectional study was carried out in children under 5 years with clinical diagnosis of invasive pneumococcus disease, assisted in two children hospitals from Santiago de Cuba during the period 2014-2018. Of the 1466 clinical samples taken and processed, in 131 the pathogen agent was isolated; these corresponded to 59 patients with clinical forms of the infection and 72 carriers of the disease. For the statistical processing of the information the absolute and relative frequencies were used as summary measures. Results: In general the positivity for S. pneumoniae was of 8.9 %, with more isolation frequencies in the samples of cerebrospinal fluid (81.8 %), pleural fluid (47.1 %) and otic exudate (21.9 %) that also coincided with the highest percentages of pneumonia (61.0), acute otitis media (23.7) and meningitis (15.3), as clinical forms of the neumococcus disease that mainly affected 1 year children, followed by those over 2 years. In a same way, 9 serotypes of S. pneumoniae were identified, with prevalence of the 19A (39.0 %), and 14 (25.4 %) and the 6A (11.9 %). In the nasopharyngeal carriers 8 serotypes were identified, of which the 19A and 14 prevailed. Lastly, a high microbian resistance to erythromycin and the combination trimethoprim-sulfametoxazole was found. Conclusions: The results of this study provided a scientific referent before the introduction of the Cuban antipneumococcus vaccine that will allow to evaluate its impact in the incidence of this disease.

Pneumococcal InfectionsABSTRACT
El objetivo de este estudio fue describir las percepciones de los usuarios de Facebook que realizaron comentarios, en las publicaciones realizadas desde la cuenta oficial del Ministerio de Salud de Perú (MINSA), referentes a la campaña de vacunación contra el VPH. Se analizaron 2748 comentarios en Python con procesamiento de lenguaje natural. Con este proceso se obtuvieron palabras claves que luego fueron interpretadas de manera manual. Se encontraron mayoritariamente cuatro tipos de discursos dentro de ellos: a) apoyo a la publicación sobre la vacuna contra el VPH; b) rechazo a la vacuna contra el VPH; c) Vacuna contra el VPH en niños; d) Dudas sobre la vacuna contra el VPH. En su mayoría, los usuarios que expresaron una postura de rechazo de esta vacuna se respaldaban de links a noticias donde se presentaba un evento supuestamente atribuido a la vacunación o inmunización pero que carecía de una fuente de información confiable y/o verificable.
The objective of this study was to describe the perceptions of Facebook users who commented on posts made by the official account of the Ministry of Health of Peru (MINSA) regarding the HPV vaccination campaign. We analyzed 2748 comments in Python with natural language processing. With this process we obtained keywords that were then interpreted manually. We found mostly four types of discourse, within them: a) support for the publications of the HPV vaccine; b) refusal of the HPV vaccine; c) HPV vaccine in children; d) doubts about the HPV vaccine. For the most part, users who expressed a position against this vaccine relied on links to online news stories that presented an event supposedly attributed to vaccination or immunization but lacked a reliable and/or verifiable source of information.
ABSTRACT
This narrative review explores the diverse representations of epilepsy in art across different historical periods, examining the intersection of artistic expression with evolving cultural, medical, and societal perceptions. Beginning with ancient and medieval depictions intertwined with religious symbolism, the paper progresses through the Renaissance, and Baroque, and transitions into modern and avant-garde movements. Each period reflects changing attitudes towards epilepsy, from divine interpretations, and religious concerns to anatomical realism and, later, explorations of psychological themes. The contemporary lens focuses on inclusive and empathetic portrayals, utilizing digital media to challenge stigmas and foster understanding.
Esta revisão narrativa explora as diversas representações da epilepsia na arte em diferentes períodos históricos, examinando a intersecção da expressão artística com a evolução das percepções culturais, médicas e sociais. Começando com representações antigas e medievais entrelaçadas com simbolismo religioso, o artigo avança através da Renascença e do Barroco, e transita para movimentos modernos e de vanguarda. Cada período reflete mudanças de atitudes em relação à epilepsia, desde interpretações divinas e preocupações religiosas até o realismo anatômico e, mais tarde, explorações de temas psicológicos. A lente contemporânea centra-se em representações inclusivas e empáticas, utilizando meios digitais para desafiar estigmas e promover a compreensão.
