Niños hospitalizados con influenza en un hospital pediátrico de Argentina durante 2019-2022: ¿qué ha cambiado luego de la pandemia por COVID-19? / Children with influenza admitted at a children's hospital in Argentina in the 2019­2022 period: What has changed after the COVID-19 pandemic?

Introducción. Durante 2020 y 2021, la circulación de los virus influenza se mantuvo por debajo de lo esperado en todo el mundo. En Argentina, en el año 2022 observamos una circulación ininterrumpida de influenza todo el año. Nuestros objetivos fueron describir los patrones de circulación y las características clínicas de niños internados con influenza. Población y métodos. Estudio retrospectivo, analítico, observacional. Se incluyeron todos los niños internados en un centro pediátrico con detección del virus influenza durante los años 2019-2022. Resultados. Se internaron 138 pacientes en 4 años; en 2019 se observó una tasa del 4,5/1000 egresos hospitalarios mientras que en 2022, fue del 15,1/1000. En 2020 y 2021 no hubo casos. En el 2019 la mayoría de los casos ocurrieron en invierno, la causa de la internación fue la infección respiratoria aguda baja (IRAB) en el 79 % y se detectó influenza A en el 92 % de los casos. En el 2022, la mayoría de los casos ocurrieron en primavera, el 62 % presentó IRAB y en el 56 % se detectó influenza A. Ambos períodos tuvieron similares frecuencias de vacunación y de comorbilidades. Conclusiones. En el 2022 se registraron más internaciones por influenza, lo que podría corresponder a que se realizaron métodos diagnósticos moleculares, que son más sensibles, y se observó un cambio en la estacionalidad con más casos en primavera. En 2019 predominó influenza A en infecciones del tracto respiratorio inferior, mientras que en el 2022 influenza A y B fueron similares, y hubo más formas extrapulmonares.

Introduction. During 2020 and 2021, the circulation of influenza virus remained below expectations worldwide. In Argentina, in 2022, we observed an uninterrupted circulation of influenza all year round. Our objectives were to describe the circulation patterns and clinical characteristics of hospitalized children with influenza. Population and methods. Retrospective, analytical, observational study. All children with influenza virus admitted to a children's hospital during the 2019­2022 period were included. Results. A total of 138 patients were admitted over 4 years; in 2019, the rate of hospital discharges was 4.5/1000, compared to 15.1/1000 in 2022. No cases were recorded in 2020 and 2021. In 2019, most cases were observed in the winter; in 79%, the cause was acute lower respiratory tract infection (ALRTI); influenza A was detected in 92%. In 2022, most cases occurred in the spring; 62% developed ALRTI; and influenza A was detected in 56%. Similar rates of vaccination and comorbidities were observed in both periods. Conclusions. In 2022, more hospitalizations due to influenza were recorded, which may have correlated with the use of more sensitive molecular diagnostic testing and a change in seasonality, with more cases observed in the spring. In 2019, influenza A predominated in lower respiratory tract infections, while in 2022, cases of influenza A and B were similar, with more extra-pulmonary forms.

Whitehead, Tansley, Sen, Bobbio e a abordagem One Health / Whitehead, Tansley, Sen, Bobbio and the One Health approach / Whitehead, Tansley, Sen, Bobbio y el enfoque One Health

Objetivo: traçar parâmetros para estruturar conceitos da abordagem One Health através dos pensamentos de Alfred North Whitehead, Arthur George Tansley, Amartya Sen e Norberto Bobbio. Metodologia: tratou-se de pesquisa original, com abordagem dedutiva e viés hermenêutico, baseada nos pensamentos selecionados e na orientação de Saúde Única. Resultados: One Health estrutura-se na afirmativa holística e integrada que a saúde humana, animal e ambiental estão interligadas. Sob a perspectiva de Whitehead, a abordagem One Health pode ser considerada um processo dinâmico e relacional, onde humanos, animais e meio ambiente interagem constantemente, interconectando-se por relações e processos, formando um todo. Pela perspectiva de Tansley, a ideia de One Health pode alinhar-se ao conceito de ecossistema, não podendo a saúde ser analisada isoladamente em indivíduos, mas, necessariamente, pelas interações complexas entre seres humanos, animais e o ambiente. Sob o prisma de desenvolvimento (direitos e liberdades), proposto por Sen, a abordagem One Health pode ser considerada um meio para alcançá-lo, através da interrelação de mecanismos, sistemas e instituições focados na promoção da saúde e do bem-estar. Na visão de Bobbio, direitos fundamentais, democracia e a paz, são formas éticas e primordiais para assegurar direitos, especialmente um novo direito da natureza (humanos, animal e ambiente) na busca conjunta de garantias para a convivência pacífica. Conclusão: a abordagem One Health não é apenas uma estratégia prática, mas também uma visão renovada da antiga percepção que reconhecia a interconexão de todas as formas de vida.

Objective: draw parameters to structure concepts of the One Health approach through the thoughts of Alfred North Whitehead, Arthur George Tansley, Amartya Sen, and Norberto Bobbio. Methodology: this was original research, with a deductive approach, hermeneutic bias based on the selected thoughts and the One Health. Results: One Health is structured on the holistic and integrated assertion that human, animal, and environmental health are interconnected. From Whitehead's perspective, the One Health approach can be considered a dynamic and relational process, where humans, animals, and the environment constantly interact, interconnecting through relationships and processes, forming a whole. From Tansley's perspective, the idea of One Health can align with the ecosystem concept, where health cannot be analyzed in isolation in individuals, but necessarily through the complex interactions between humans, animals, and the environment. From Sen's development prism (rights and freedoms), the One Health approach can be seen to achieve it, through the interrelation of mechanisms, systems, and institutions focused on promoting health and well-being. In Bobbio's view, fundamental rights, democracy, and peace are ethical and primary ways to ensure rights, especially a right of nature (humans, animals, and the environment) in the joint pursuit of guarantees for peaceful coexistence. Conclusion: the One Health approach is not just a practical strategy, but also a renewed vision of the old perception that recognized the interconnection of all forms of life.

Utilização da toxina botulínica para o tratamento de cicatriz queloide: revisão de escopo / Use of botulinum toxin for the treatment of keloid scars: scoping review

Introdução: Cicatrizes visíveis podem acarretar agravos, sejam estéticos, psicológicos, funcionais ou sociais, principalmente de grande extensão e volume, como os queloides. A descoberta de novos tratamentos de queloides não é fácil, visto a presença de alguns entraves metodológicos e éticos, sendo uma área pouco explorada. A toxina botulínica tem sido apresentada como alternativa terapêutica em estudos nacionais e internacionais, sendo necessária uma compilação e destaque dos principais estudos que possam subsidiar a prática clínica. Assim, o objetivo foi apresentar uma revisão de escopo sobre a utilização terapêutica da toxina botulínica para o tratamento de cicatrizes queloides. Método: A revisão foi realizada através da estratégia PICO e utilizando o Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews. Foi realizada nas bases de dados PubMed/ Medline, Biblioteca Virtual em Saúde e SciELO, considerando estudos do período de 2016 até setembro de 2021. Resultados: Foram encontrados 34 artigos no geral relacionados ao tema. Após filtragem e seleção, a revisão foi construída com apoio de 5 artigos. Os estudos variaram entre coorte, relatos de caso, ensaio clínico randomizado e caso-controle. Foi possível observar como principais resultados a ação a curto prazo da toxina botulínica na redução de queloides, maior efetividade na redução dos sintomas e possibilidades de utilização clínica para diferentes populações e manifestações clínicas. Conclusão: O mecanismo de ação da toxina botulínica pode facilitar o tratamento de queloides e redução de sintomas, sendo necessários estudos mais robustos para definição de protocolos cínicos de gestão de cicatrizes.

Introduction: Visible scars can cause problems, whether aesthetic, psychological, functional, or social, mainly of great extension and volume, such as keloids. The discovery of new treatments for keloids is not easy, given the presence of some methodological and ethical obstacles, and it is an area that is little explored. Botulinum toxin has been presented as a therapeutic alternative in national and international studies, requiring a compilation and highlighting of the main studies that can support clinical practice. Thus, the objective was to present a scoping review on the therapeutic use of botulinum toxin for the treatment of keloid scars. Method: The review was carried out using the PICO strategy and using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. It was carried out in the PubMed/ Medline, Virtual Health Library, and SciELO databases, considering studies from 2016 to September 2021. Results: Overall, 34 articles related to the topic were found. After filtering and selection, the review was constructed with the support of 5 articles. The studies varied between cohorts, case reports, randomized clinical trials, and casecontrol. It was possible to observe as main results of the short-term action of botulinum toxin in reducing keloids, greater effectiveness in reducing symptoms, and possibilities of clinical use for different populations and clinical manifestations. Conclusion: The mechanism of action of botulinum toxin can facilitate the treatment of keloids and reduce symptoms, requiring more robust studies to define effective scar management protocols.

Resistencia a los inhibidores de la integrasa en niños con el virus de la inmunodeficiencia humana por transmisión vertical: primeros casos en Uruguay / Resistance to integrase inhibitors in children with vertically-transmitted human immunodeficiency virus: First cases in Uruguay

La resistencia a los antirretrovirales (ARV) es un problema de salud pública. Con el uso de inhibidores de la integrasa (INSTI) en pediatría, también comienzan a aparecer resistencias. El objetivo de esta comunicación es describir 3 casos con resistencia a los INSTI. Se describen 3 pacientes pediátricos con transmisión vertical del virus de la inmunodeficiencia humana (VIH). Iniciaron ARV de lactantes y preescolares, con mala adherencia al tratamiento, cursaron con diferentes planes secundarios a comorbilidades asociadas y fallas virológicas por resistencia. Los 3 casos clínicos describen la rápida aparición de resistencia frente a la falla virológica y el compromiso de los INSTI. La adherencia debe ser supervisada para detectar precozmente el aumento de la viremia. La falla virológica en un paciente tratado con raltegravir obliga a un rápido cambio de esquema ARV, ya que continuar utilizándolo podría favorecer nuevas mutaciones y resistencia a los INSTI de segunda generación.

Antiretroviral (ARV) drug resistance is a public health issue. Resistance has also been observed in the case of integrase strand transfer inhibitors (INSTIs) used in pediatrics. The objective of this article is to describe 3 cases of INSTI resistance. These are the cases of 3 children with vertically-transmitted human immunodeficiency virus (HIV). They were started on ARVs as infants and preschoolers, with poor treatment adherence, and had different management plans due to associated comorbidities and virological failure due to resistance. In the 3 cases, resistance developed rapidly as a result of virological failure and INSTI involvement. Treatment adherence should be monitored so that any increase in viremia can be detected early. Virological failure in a patient treated with raltegravir forces to a rapid change in ARV therapy because its continued use may favor new mutations and resistance to second-generation INSTIs.

Distribución de nutricionistas en el sistema de salud peruano: un panorama por niveles de atención

La prestación de servicios para la atención integral de la salud requiere la participación de diversos profesionales con competencias específicas para brindar la mejor atención posible a la población. La inclusión del nutricionista en los diferentes niveles del sistema de salud es crucial para garantizar una atención integral en las diversas etapas de la vida. Una distribución inequitativa de nutricionistas en los niveles de atención puede conducir a una fragmentación de la atención y la pérdida de oportunidades para abordar los problemas relacionados con la alimentación y nutrición. Por ello, se desarrolló un estudio con el objetivo de describir la distribución de nutricionistas en los establecimientos de salud según el nivel de atención, y evaluar el cumplimiento de las recomendaciones de recursos humanos establecidas por la norma técnica de las UPSS de Nutrición y Dietética. Se desarrolló un estudio descriptivo y transversal, mediante el análisis de fuentes secundarias. Se utilizaron los datos de recursos humanos por IPRESS de SUSALUD, del año 2022. Se consideró la Norma técnica de UPSS de Nutrición y Dietética para evaluar el cumplimiento de las recomendaciones de recursos humanos. Entre los principales resultados, se identificó que el 7.93% de los establecimientos de salud del primer nivel de atención tienen al menos un nutricionista. En el segundo nivel de atención, el 96.35% de los establecimientos de salud no cumplen con las recomendaciones de recursos humanos de la norma técnica, y ningún establecimiento del tercer nivel de atención cumplió esta recomendación. La distribución de nutricionistas en los diversos niveles de atención del sistema de salud peruano es desigual. Es necesario mejorar la planificación de recursos humanos en el sistema de salud peruano para garantizar una atención integral de la salud a la población.

The provision of services for comprehensive healthcare requires the involvement of various professionals with specific competencies to provide the best possible care to the population. The inclusion of nutritionists at different levels of the healthcare system is crucial to ensure comprehensive care at various stages of life. An unequal distribution of nutritionists across healthcare levels can lead to fragmented care and missed opportunities to address nutrition-related issues. Therefore, a study was conducted with the aim of describing the distribution of nutritionists in healthcare facilities according to the level of care and evaluating compliance with the human resources recommendations established by the technical standard of Nutrition and Dietetics UPSS. A descriptive and cross-sectional study was conducted using the analysis of secondary sources. Human resources data from SUSALUD for the year 2022 were used. The Technical Standard of UPSS of Nutrition and Dietetics was considered to assess compliance with human resources recommendations. Among the main findings, it was identified that 7.93% of first-level healthcare facilities have at least one nutritionist. In the second level of care, 96.35% of healthcare facilities do not comply with the human resources recommendations of the technical standard, and no third-level healthcare facility met this recommendation. The distribution of nutritionists across various levels of care in the Peruvian healthcare system is unequal. It is necessary to improve human resources planning in the Peruvian healthcare system to ensure comprehensive healthcare for the population..

Acceso y adhesión a proceso de intervención psicosocial diferenciado para los servicios y sistemas de salud en varones gay adultos viviendo con el VIH, Paraguay, 2022 / Access and adherence to a differentiated psychosocial intervention process for health services and systems in adult gay men living with HIV, Paraguay, 2022

Introducción: el acceso a los servicios de salud en Paraguay, está determinado por varios tipos de barreras. Por ello, es preciso describir el impacto que tienen las políticas públicas y sus implicancias en la mitigación de las mismas. Objetivo: describir el acompañamiento diferenciado y su contribución al apoyo socio emocional, adhesión al tratamiento y acceso a servicios de salud en el área de atención a personas varones que viven con el VIH. Metodología: estudio de carácter cualitativo, descriptivo, con entrevistas semi estructuradas y muestra no probabilística, dirigida e intencional; Resultados: este estudio cualitativo exploró las experiencias de personas viviendo con VIH que recibieron acompañamiento psicosocial diferenciado en un servicio de atención integral. Los participantes destacaron la importancia del acompañamiento para afrontar la crisis posterior al diagnóstico. La orientación presencial, escucha empática y seguimiento facilitaron la vinculación y adherencia al servicio de salud y al tratamiento antirretroviral. El apoyo psicosocial fue clave para desmitificar ideas erróneas sobre el VIH/SIDA, empoderarse sobre su estado serológico y mejorar la calidad de vida. Se enfatizó el rol de los grupos de pares para brindar contención. Algunos participantes reportaron experiencias previas de revelación no consentida y vulneración de confidencialidad. El acompañamiento psicosocial diferenciado resultó fundamental para facilitar la inserción y permanencia de las personas con VIH en los servicios de atención integral (adhesión al tratamiento). Conclusiones: el acompañamiento psicosocial diferenciado resultó clave para facilitar la vinculación y adherencia en personas con VIH. La atención integral requiere identificar situaciones particulares, establecer relaciones de confianza y comunicación efectiva. El apoyo inicial es fundamental brindando contención ante el impacto emocional del diagnóstico. El seguimiento continuo es esencial dada la doble discriminación. La confidencialidad y capacidad de generar vínculos empáticos son elementos centrales. Los factores mencionados favorecen la adhesión al tratamiento. Los resultados sugieren que estas prácticas psicosociales pueden optimizar modelos de atención integral a personas con VIH.

Introduction: access to healthcare services in Paraguay is influenced by various barriers. Thus, it is essential to describe the impact of public policies and their implications in mitigating these barriers. Objective: to describe the differentiated support and its contribution to socio-emotional support, therapeutic adherence, and access to healthcare services in the area of care for males living with HIV. Methodology: a qualitative, descriptive study with semi-structured interviews and a non-probabilistic, directed, and intentional sample. Results: this qualitative study explored the experiences of individuals living with HIV who received differentiated psychosocial support in an integrated care service. Participants emphasized the importance of support in coping with the post-diagnosis crisis. In-person guidance, empathetic listening, and follow-up facilitated engagement and adherence to healthcare services and antiretroviral treatment. Psychosocial support played a critical role in debunking misconceptions about HIV/AIDS, empowering individuals regarding their serostatus, and improving their quality of life. The role of peer groups in providing emotional support was emphasized. Some participants reported previous experiences of non-consensual disclosure and confidentiality breaches. Differentiated psychosocial support was essential in promoting the integration and retention of people with HIV in integrated care services (therapeutic adherence). Conclusions: differentiated psychosocial support was crucial in facilitating the engagement and adherence of individuals with HIV. Comprehensive care necessitates identifying specific situations, establishing trust-based relationships, and effective communication. Initial support is vital for providing emotional support in the face of the diagnostic impact. Ongoing follow-up is essential due to the dual discrimination faced. Confidentiality and the ability to build empathetic relationships are central elements. The aforementioned factors favor adherence to treatment. The results suggest that these psychosocial practices can enhance models of comprehensive care for people with HIV.

Albúmina en cirrosis: perspectiva inflamatoria / Albumin in cirrhosis: inflammatory perspective

La albúmina sérica humana es la proteína más abundante en el plasma, su estructura molecular le confiere estabilidad, pero también flexibilidad para ligar y transportar un amplio rango de moléculas. Su función oncótica es la propiedad más reconocida que la lleva a introducirse en la terapéutica médica como un expansor de volumen. Sin embargo, en los últimos años se le han adicionado funciones con carácter antioxidante, inmunomodulador y de estabilización endotelial, que hacen presumir que su impacto terapéutico está más allá de sus funciones volumétricas. En los últimos años, específicamente en la cirrosis y la falla hepática aguda sobre crónica, se ha tenido un cambio en el paradigma fisiológico, desde una perspectiva netamente hemodinámica hacia una perspectiva inflamatoria, en donde las funciones oncóticas y no oncóticas de la albúmina están alteradas y tienen un carácter pronóstico en estas entidades. Este conocimiento creciente, desde una perspectiva inflamatoria, hace que se fortalezca el uso terapéutico de la albúmina sérica humana desde las indicaciones tradicionales como prevención de la disfunción circulatoria posparacentesis, prevención y tratamiento de lesión renal aguda, hasta las discusiones para administración a largo plazo en pacientes cirróticos con ascitis.

Human serum albumin is the most abundant protein in plasma, with a molecular structure that provides stability while also allowing flexibility to bind and transport a wide range of molecules. Its oncotic function is the most recognized property, leading to its introduction in medical therapy as a volume expander. However, in recent years, additional functions with antioxidant, immunomodulatory, and endothelial stabilization properties have been identified, suggesting that its therapeutic impact extends beyond its volumetric functions. Specifically, in cirrhosis and acute-on-chronic liver failure, there has been a shift in the pathophysiological paradigm from a purely hemodynamic perspective to an inflammatory perspective, where both oncotic and non-oncotic functions of albumin are altered and have prognostic significance in these conditions. This growing understanding from an inflammatory perspective strengthens the therapeutic use of human serum albumin, not only for traditional indications such as the prevention of post-paracentesis circulatory disfunction, prevention and treatment of acute kidney injury, but also for discussions regarding long-term administration in cirrhotic patients with ascites.

Nutritional composition of human milk and its association with maternal and perinatal factors / Composição nutricional do leite humano e sua associação com fatores maternos e perinatais

ABSTRACT Objective: The objective of this study was to evaluate the influence of maternal and perinatal factors on the nutritional composition of human milk. Methods: A cross-sectional study was conducted between November 2018 and January 2020, with 181 donors selected in Tertiary Health Units of the Unified Health System — from one collection station and five Human Milk Banks. Data were collected through a standardized questionnaire. To be fit to be a donor in a Human Milk Banks and produce mature milk were the eligibility criteria to participate in the study. We excluded milk samples with Dornic acidity above 8° D. The dependent variables were the macronutrients of human milk (i.e., carbohydrates, proteins, lipids, and total energy), that were analyzed using spectroscopy with the Miris Human Milk Analyzer™. The maternal and perinatal factors were the independent variables. Results: Women with pre-gestational obesity and gestational weight gain above the recommendation showed a lower protein concentration compared to eutrophic women (median=0.8, interquartile range (IQR): 0.7-0.9 vs. median=0.8, and IQR: 0.8-1.0) and those with adequate gestational weight gain (median=0.8, IQR: 0.7-0.9 vs. median=0.9, and IQR: 0.8-1.0), respectively. The other analyzed factors (i.e., maternal habits, comorbidities, and perinatal factors) were not associated with the nutritional composition of human milk. Conclusions: The assessment of factors associated with the nutritional composition of human milk is extremely important to assist postpartum care. Pre-gestational obesity and inadequate gestational weight gain were the only factors statistically associated with the nutritional composition of human milk as they impacted its protein content.

RESUMO Objetivo: Avaliar a influência de fatores maternos e perinatais na composição nutricional do leite humano. Métodos: Estudo transversal, realizado entre novembro de 2018 e janeiro de 2020, com 181 doadoras selecionadas em Unidades Terciárias de Saúde do Sistema Único de Saúde de um Posto de Coleta e cinco Bancos de Leite Humano. Foram coletados dados das variáveis maternas e dos recém-nascidos por meio de questionário padronizado. Estar apta para ser doadora em um Banco de Leite Humano e produzir leite maduro foram os critérios de elegibilidade para participar do estudo. As amostras de leite com acidez Dornic acima de 8° D foram excluídas. Os macronutrientes do leite humano, variáveis dependentes (carboidratos, proteínas, lipídeos, energia total) foram analisados pela técnica de espectroscopia de transmissão no infravermelho médio com o Miris Human Milk Analyzer™. Os fatores maternos e perinatais foram as variáveis independentes. Resultados: Mulheres com obesidade pré-gestacional e ganho de peso gestacional acima do recomendado apresentaram menor concentração proteica em relação às eutróficas (mediana=0,8, intervalo interquartil [IQR]: 0,7-0,9 vs. mediana=0,8, IQR: 0,8-1,0) e aquelas com ganho de peso gestacional adequado (mediana=0,8, IQR: 0,7-0,9 vs. mediana=0,9, IQR: 0,8-1,0), respectivamente. Os demais fatores analisados (hábitos maternos, comorbidades, fatores perinatais) não se associaram com a composição nutricional do leite humano. Conclusões: A avaliação dos fatores associados à composição nutricional do leite humano é de extrema importância para auxiliar os cuidados pós-parto. A obesidade pré-gestacional e o ganho de peso gestacional inadequado foram os únicos fatores estatisticamente associados com a composição nutricional do leite humano por terem impactado o seu teor de proteína.

Ocular manifestation of vertical transmission of dengue: case report / Manifestação ocular de transmissão vertical de dengue: relato de caso

ABSTRACT A 7-week-old male delivered by cesarean section presented with a positive serology for dengue along with preretinal and retinal hemorrhages, vitreous opacities and cotton wool spots. The patient and his mother had positive serologies for Non Structural Protein 1 (NS1) by ELISA. Retinal and vitreous findings improved over a sixteen-week period. Spectral domain optical coherence tomography (OCT) showed preserved macular architecture. In this case report, we suggest that retinal and vitreous changes may be the ocular presenting features of vertically transmitted dengue in newborns, and that those findings may resolve with no major structural sequelae.

RESUMO Neonato de 7 semanas, do sexo masculino, nascido de parto cesárea, apresentou sorologia positiva para dengue com hemorragias retinianas e pré-retinianas, opacidades vítreas e manchas algodonosas. O paciente e sua mãe haviam apresentado sorologias positivas para Non Structural Protein 1 através de ELISA. Achados na retina e no vítreo melhoraram em um período de dezesseis semanas. O exame de tomografia de coerência óptica de domínio espectral demonstrou arquitetura macular preservada. Neste relato de caso, sugerimos que alterações na retina e no vítreo podem ser os achados oculares aparentes em neonatos com infecção vertical por dengue, e que estes podem se resolver sem maiores sequelas estruturais.

Adult-onset idiopathic opsoclonus-myoclonus syndrome / Síndrome de opsoclonia-mioclonia idiopática de início adulto

ABSTRACT Purpose: Opsoclonus-myoclonus syndrome is extremely uncommon in adults with an autoimmune pathophysiology. Because of the rarity of the syndrome, international recognition of opsoclonus-myoclonus-ataxia syndrome needs to be improved urgently. Therefore, the goal of this study was to raise the awareness of the opsoclonus-myoclonus-ataxia syndrome and help doctors in better diagnosing and using immunotherapy. Methods: We present a case study of an adult-onset case of idiopathic opsoclonus-myoclonus syndrome characterized by spontaneous arrhythmic multidirectional conjugate eye movements, myoclonus, ataxia, sleep disorders, and intense fear. Additionally, we conduct a literature search and summarize the pathophysiology, clinical presentation, diagnosis, and treatment of opsoclonus-myoclonus-ataxia syndrome. Results: Immunotherapies successfully treated the patient's opsoclonus, myoclonus, and ataxia. Further, the article also includes an update summary of the opsoclonus-myoclonus-ataxia syndrome. Conclusion: The prevalence of residual sequela in adults with opsoclonus-myoclonus-ataxia syndrome is low. Early diagnosis and treatment may result in a better prognosis. Furthermore, combined immunotherapy is expected to reduce the incidence of refractory and reoccurring opsoclonus-myoclonus-ataxia syndrome.

RESUMO Objetivo: A síndrome de opsoclonia-mioclonia é extremamente rara em adultos e tem uma fisiopatologia autoimune. Devido à raridade dessa síndrome, o reconhecimento da síndrome de opsoclonia-mioclonia-ataxia precisa melhorar urgentemente em todo o mundo. Assim sendo, este estudo visou aumentar a conscientização sobre a síndrome de opsoclonia-mioclonia-ataxia e ajudar os médicos para um melhor diagnóstico e o uso correto da imunoterapia. Métodos: Este é o relato de um caso adulto de síndrome de opsoclonia-mioclonia idiopática com movimentos oculares conjugados, multidirecionais, arrítmicos e espontâneos, mioclonia, ataxia, distúrbios do sono e medo intenso. Além disso, foram pesquisadas as publicações recentes relevantes e resumiu-se a fisiopatologia, a apresentação clínica, o diagnóstico e o tratamento da síndrome de opsoclonia-mioclonia-ataxia. Resultados: A paciente recuperou-se totalmente da opsoclonia, da mioclonia e da ataxia através de imunoterapia. O artigo também fornece um resumo atualizado sobre a síndrome de opsoclonia-mioclonia-ataxia. Conclusão: Adultos com síndrome de opsoclonia-mioclonia-ataxia têm uma baixa frequência de sequelas residuais. O diagnóstico e o tratamento precoces podem levar a melhores prognósticos. Espera-se que a imunoterapia combinada reduza a incidência da síndrome de opsoclonia-mioclonia-ataxia refratária e recorrente.

Evolução das desigualdades na distribuição de dentistas no Brasil / The evolution of inequalities in the distribution of dentists in Brazil

Resumo O objetivo deste artigo é analisar a evolução da distribuição de dentistas e cursos de graduação em odontologia no Brasil entre 1960 e 2022, a partir de dados institucionais e de sua correlação com dados econômicos e demográficos. Foram calculadas as proporções entre número de dentistas e população para as unidades federativas em diferentes períodos, e para determinar a concentração de dentistas, da população e dos cursos de graduação em odontologia,foi utilizado o índice Herfindahl-Hirschman (HHI). Para testar a correlação entre variáveis foi empregado o teste de Pearson, com um nível de significância de 95%. Entre 1960 e 2022, a proporção de dentistas por 10 mil habitantes aumentou de 3,3 para 16,9. Ainda em 2022, as unidades federativas com maior renda média domiciliar per capita estavam fortemente correlacionadas à maior concentração de dentistas (R2 = 0,90; p < 0,00). Entretanto, de 1975 a 2022, a concentração de dentistas medida pelo HHI caiu de 45,1 para 33,4. A diminuição da concentração geográfica dos cursos de odontologia foi ainda mais pronunciada, tendo o HHI passado de 39,3 em 1991 para 25,6 em 2022.

Abstract The scope of this article is to analyze the evolution of the distribution of dentists and undergraduate courses in Dentistry in Brazil between 1960 and 2022, based on institutional data and its correlation with economic and demographic data. The proportions between number of dentists and population were calculated for the federative units in different periods, and the Herfindahl-Hirschman Index (HHI) was used. to determine the concentration of dentists, population and undergraduate courses in Dentistry. The Pearson test was used, with a significance level of 95%, to test the correlation between variables. In the period from 1960 to 2022, the ratio of dentists per 10,000 inhabitants increased from 3.3 to 16.9. Moreover in 2022, the federative units with the highest average household income per capita were closely correlated with the highest concentration of dentists (R2= 0.90; p < 0.00). However, from 1975 to 2022, the concentration of dentists measured by the HHI dropped from 45.1 to 33.4. The decrease in the geographic concentration of Dentistry courses was even more pronounced, with the HHI rising from 39.3 in 1991, to 25.6 in 2022.

Human papillomavirus DNA testing with the urine sample is not yet available: the accuracy of two distinct kits

SUMMARY OBJECTIVE: The aim of this study was to assess the results and efficiency of two real-time polymerase chain reaction procedures for detecting human papillomavirus utilizing urine samples. METHODS: This study comprised 151 patients who had previously tested positive for human papillomavirus in their cervical samples. Two different commercial real-time polymerase chain reaction techniques were used for identification and genotyping human papillomavirus in urine specimens. The urine samples of 151 patients were evaluated via the Roche Cobas test, and the urine samples of 91 patients were also evaluated via the Qiagen test. RESULTS: The overall consistency of urine and cervical swab specimens for the identification of human papillomavirus in Roche Cobas and Qiagen tests were 44.8 and 44%, respectively. The rates of positive human papillomavirus results from urine samples were 57 and 70.3%, respectively. The overall concordance among Roche Cobas and Qiagen tests utilizing urine samples for human papillomavirus type 16/18 was 84.3% with a kappa value of 0.675, and for other high-risk-human papillomavirus, it was 75.60% with a kappa value of 0.535. Roche Cobas showed high concordance with Qiagen test. CONCLUSION: human papillomavirus positivity was not detected in all urine samples. It is still inappropriate to recommend the use of urine liquid biopsy for the accurate and reliable detection of human papillomavirus. Due to the lack of a standardized tool, the utilization of urine samples as a screening human papillomavirus test remains a challenge.

Abstract Introduction The violent repression that occurred in Chile during the social outbreak (2019-2020) left an unprecedented number of people injured as a result of ocular and maxillofacial trauma as a result of the action by state agents, unleashing a socio-sanitary crisis that required the approach of health problems with an emphasis on structural and functional damage. Objective To analyze the daily experience of people affected by ocular and/or maxillofacial trauma from a human rights perspective, with emphasis on providing background information that contributes to functional and psychosocial support processes. Method Study with a qualitative approach, considering the analysis of three in-depth interviews focused on the daily experience produced as a result of police violence. These were analyzed based on the content analysis technique, with subsequent triangulation. Results A series of interferences and daily repercussions as a result of the trauma were observed, generating the phenomenon of an interfered daily life in addition to self-estrangement. The contrast between the experiences and expectations of health care and reparation processes was discussed, which are still insufficient and tend towards re-victimization. Conclusion Access to functional and psychosocial rehabilitation is a fundamental part of the processes of integral and psychosocial repair for the people who lived through these traumatic experiences during the social outbreak. It is essential that health and judicial mechanisms deepen approaches from a human rights perspective, incorporating the gender approach to comply with the principles of truth, justice, reparation, and guarantees of non-repetition.

Polyphenol analysis in human milk by a rapid, cost-effective, and accurate micromethod: translational development / Análise de polifenóis no leite humano por meio de um micrométodo rápido, econômico e preciso: desenvolvimento translacional

ABSTRACT Objective: To develop a rapid method for analysing polyphenols, which are potentially active antioxidants against neonatal oxidative stress, from small human milk (HM) volumes. Methods: Acid and alkaline extractions were compared using two dyes: Folin-Ciocalteu and Fast Blue BB. Linearity, sensitivity, recovery percentage, polyphenol content, precision, and stability were assessed in 14 HM samples and compared using the Kruskal-Wallis H test (p<0.05). The best technique was applied to 284 HM samples to determine their polyphenolic content and its association with maternal diet by multifactorial linear regression. Results: Acidic extraction successfully recovered the gallic acid reference standard, whereas alkaline extraction overestimated it. Calibration curves for all methods were linear (R2>0.96) up to 500 mg/L. All bicarbonate-based Folin-Ciocalteu methods assayed were stable and repeatable, whereas Fast Blue BB-based variants were not. HM polyphenols (mean=94.68 mg/L) positively correlated to the dietary intake of hydroxycinnamic acids, the most consumed polyphenolic family in this population. Conclusions: A bicarbonate-based Folin-Ciocalteu micromethod allowed the accurate determination of polyphenols in HM, which might be useful for translational research settings and HM banks.

RESUMO Objetivo: Desenvolver um método rápido para analisar polifenóis, que são antioxidantes potencialmente ativos contra o estresse oxidativo neonatal, em pequenos volumes de leite humano (LH). Métodos: Foram comparadas extrações ácidas e alcalinas usando dois corantes: Folin-Ciocalteu e Fast Blue BB. Foram avaliadas variáveis como linearidade, sensibilidade, percentagem de recuperação, teor de polifenóis, precisão e estabilidade em 14 amostras de LH, comparadas usando o teste de Kruskal-Wallis H (p<0,05). A melhor técnica foi aplicada a 284 amostras de LH para determinar seu teor polifenólico e sua associação com a dieta materna por regressão linear multifatorial. Resultados: A extração ácida recuperou com sucesso o padrão de referência do ácido gálico, enquanto a extração alcalina o superestimou. As curvas de calibração para todos os métodos foram lineares (R2>0,96) até os 500 mg/L. Todos os métodos testados baseados em Folin-Ciocalteu com bicarbonato foram estáveis e repetíveis, enquanto as variantes baseadas em Fast Blue BB não. Os polifenóis do HM (média=94,68 mg/L) correlacionaram-se positivamente com a ingestão dietética de ácidos hidroxicinâmicos, a família de polifenóis mais consumida nesta população. Conclusões: Um micrométodo baseado em bicarbonato de Folin-Ciocalteu permitiu a determinação precisa de polifenóis no HM, o que pode ser útil para configurações de pesquisa translacional e bancos de HM.

First case of envenomation in humans caused by the banded cat-eyed snake Leptodeira annulata (Linnaeus, 1758) (Squamata: Dipsadidae) in Brazil

ABSTRACT A 22-year-old female researcher was bitten by a Leptodeira annulata on the index finger of the left hand during a contention activity. After removing the snake, a little bleeding and redness was observed in the bite region, accompanied by fang marks. Thirty minutes later, edema had progressed to the dorsum of the hand. After four hours, edema persisted, but the bitten area was slightly whitened. Treatment consisted of antibiotics and anti-inflammatory drugs. The edema resolved completely and disappeared after 48 hours. Overall, this report presents the first case of envenomation in humans caused by Leptodeira annulata in Brazil.
