Association between the practice of fitness-related exercises and body image dissatisfaction in adolescents from Curitiba (PR), Brazil / Associação entre a prática de exercícios físicos relacionados ao fitness e insatisfação com a imagem corporal em adolescentes de Curitiba (PR), Brasil

ABSTRACT Objective: The aim of this study was to analyze the association between participation in fitness-related exercises (FRE) and body image dissatisfaction (BID) in adolescents and evaluate the interaction between physical exercise and nutritional status in this association. Methods: A cross-sectional study was conducted in 2015 involving 799 adolescents (10-16 years old) from 14 public schools in Curitiba (PR), Brazil. BID was assessed using the Body Shape Questionnaire and the Silhouette Scale. The FRE was classified as "does not practice," "practices ≤300 min/week," and "practices >300 min/week" by the Physical Activity Questionnaire for Adolescents. Poisson and multinomial logistic regressions, adjusted for sex, sexual maturation, and nutritional status analyzed the association of FRE and BID. Results: The BID prevalence was 28.3%; 52.4% of the adolescents wanted to reduce their silhouettes; and 48.7% did not practice FRE. Adolescents who practiced FRE >300 min/week had a 28% higher prevalence for some level of BID (PR 1.28; 95%CI 1.08-1.52) and a 46% lower chance of wanting to reduce silhouettes (OR 0.54; 95%CI 0.35-0.82), compared to nonpractitioners. There was no interaction between FRE and nutritional status in association with BID. Conclusions: The adolescents who practice FRE >300 min/week are likely to have some level of BID and are less likely to report the desire to increase their silhouettes, regardless of their nutritional status.

RESUMO Objetivo: Analisar a associação entre a participação em exercícios físicos relacionados ao fitness (EFRF) e a insatisfação com a imagem corporal (IIC) em adolescentes e avaliar a interação entre os exercícios físicos e o estado nutricional nesta associação. Métodos: Estudo transversal realizado em 2015 com 799 adolescentes (10 a 16 anos) de 14 escolas públicas de Curitiba (PR), Brasil. A IIC foi avaliada por meio do Body Shape Questionnaire e da Escala de Silhuetas. A participação em EFRF foi avaliada pelo Questionário de Atividade Física para Adolescentes e classificada em "não pratica", "pratica ≤300 minutos/semana" e "pratica >300 minutos/semana". As regressões de Poisson e logística multinomial, ajustadas por sexo, maturação sexual e estado nutricional, analisaram a associação entre EFRF e IIC. Resultados: A prevalência de IIC foi de 28,3%; 52,4% dos adolescentes queriam reduzir a silhueta e 48,7% não praticavam a EFRF. Adolescentes que praticavam EFRF >300 minutos/semana tiveram prevalência 28% maior para algum nível de IIC (razão de prevalência — RP 1,28; intervalo de confiança de 95% — IC95% 1,08-1,52) e chance 46% menor de querer reduzir silhuetas (OR 0,54; 95IC% 0,35-0,82), comparados aos não praticantes. Não houve interação entre os EFRF e o estado nutricional na associação com IIC. Conclusões: Os adolescentes que praticam EFRF >300 minutos/semana estão mais propensos a apresentar algum nível de IIC e têm menores chances de reportar o desejo de aumentar silhuetas, independentemente do estado nutricional.

Environmental sympatry through time: spatio-temporal distribution and conservation status of two sympatric anuran species (Leptodactylidae) in South America / Simpatría ambiental a través del tiempo: distribución espacio-temporal y estado de conservación de dos especies de anuros simpátricos (Leptodactylidae) en América del Sur

Abstract Introduction: Leptodactylus latinasus and Physalaemus cuqui are sympatric anuran species with similar environmental requirements and contrasting reproductive modes. Climatic configuration determines distribution patterns and promotes sympatry of environmental niches, but specificity/selectivity determines the success of reproductive modes. Species distribution models (SDM) are a valuable tool to predict spatio-temporal distributions based on the extrapolation of environmental predictors. Objectives: To determine the spatio-temporal distribution of environmental niches and assess whether the protected areas of the World Database of Protected Areas (WDPA) allow the conservation of these species in the current scenario and future. Methods: We applied different algorithms to predict the distribution and spatio-temporal overlap of environmental niches of L. latinasus and P. cuqui within South America in the last glacial maximum (LGM), middle-Holocene, current and future scenarios. We assess the conservation status of both species with the WDPA conservation units. Results: All applied algorithms showed high performance for both species (TSS = 0.87, AUC = 0.95). The L. latinasus predictions showed wide environmental niches from LGM to the current scenario (49 % stable niches, 37 % gained niches, and 13 % lost niches), suggesting historical fidelity to stable climatic-environmental regions. In the current-future transition, L. latinasus would increase the number of stable (70 %) and lost (20 %) niches, suggesting fidelity to lowland regions and a possible trend toward microendemism. P. cuqui loses environmental niches from the LGM to the current scenario (25 %) and in the current-future transition (63 %), increasing the environmental sympathy between both species; 31 % spatial overlap in the current scenario and 70 % in the future. Conclusion: Extreme drought events and rainfall variations, derived from climate change, suggest the loss of environmental niches for these species that are not currently threatened but are not adequately protected by conservation units. The loss of environmental niches increases spatial sympatry which represents a new challenge for anurans and the conservation of their populations.

Resumen Introducción: Leptodactylus latinasus y Physalaemus cuqui son especies de anuros simpátricos con requerimientos ambientales similares y modos reproductivos contrastantes. La configuración climática determina los patrones de distribución y promueve la simpatría de los nichos ambientales, pero la especificidad/selectividad determina el éxito de los modos reproductivos. Los modelos de distribución de especies (MDE) son una herramienta valiosa para predecir distribuciones espacio-temporales basadas en la extrapolación de predictores ambientales. Objetivos: Determinar la distribución espacio-temporal de los nichos ambientales y evaluar si las áreas protegidas de la base de Datos Mundial de Áreas Protegidas (DMAP) permiten la conservación de estas especies en el escenario actual y futuro. Métodos: Aplicamos diferentes algoritmos para predecir la distribución y superposición espacio-temporal de nichos ambientales de L. latinasus y P. cuqui dentro de América del Sur en el último máximo glacial (UGM), Holoceno medio, actual y futuro. Evaluamos el estado de conservación de ambas especies con las unidades de conservación de la DMAP. Resultados: Todos los algoritmos aplicados mostraron un alto rendimiento para ambas especies (TSS = 0.87, AUC = 0.95). Las predicciones de L. latinasus mostraron amplios nichos ambientales desde LGM hasta el escenario actual (49 % de nichos estables, 37 % de nichos ganados y 13 % de nichos perdidos), sugiriendo fidelidad histórica por regiones climático-ambientales estables. En la transición actual-futura L. latinasus incrementaría la cantidad de nichos estables (70 %) y perdidos (20 %), sugiriendo fidelidad por regiones de tierras bajas y la posible tendencia hacia el microendemismo. P. cuqui pierde nichos ambientales desde el LGM al escenario actual (25 %) y en la transición actual-futura (63 %), incrementando la simpatría ambiental entre ambas especies; 31 % de superposición espacial en el escenario actual y 70 % en el futuro. Conclusión: Los eventos de sequía extrema y las variaciones de precipitaciones, derivados del cambio climático, sugieren la pérdida de nichos ambientales para estas especies, actualmente no se encuentran amenazadas, pero no están adecuadamente protegidas por las unidades de conservación. La pérdida de nichos ambientales aumenta la simpatría espacial que representa un nuevo desafío para estos anuros y la conservación de sus poblaciones.

Precipitation explains Wood Thrush (Hylocichla mustelina) occupancy patterns in Northern Costa Rica / Patrones de ocurrencia del Zorzal del Bosque (Hylocichla mustelina) explicados por la precipitación en el Norte de Costa Rica

Abstract Introduction: The Wood Thrush is a migratory bird that has experienced dramatic declines in its populations in recent decades. This species overwinters in forest fragments with intermediate levels of habitat modification in Central America. However, more studies detailing the use of remnant forests through time are needed to elucidate the threats this species faces in the wintering grounds. Objective: To understand the effects of environmental and forest structure variables on the occupancy of Wood Thrush in Northern Costa Rica. Methods: The study area was the Área de Conservación Guanacaste (ACG), located in Northern Costa Rica, in December 2016, and during the 2018-2019 migration season. We estimated Wood Thrush occupancy and detection probability in four locations of ACG (dry forest, cloud forest, and two locations in the wet forest) using single-season occupancy models. We also estimated Wood Thrush occupancy and probability of persistence in different months in three vegetation types (open area, secondary forest, and old-growth forest) in the wet forest of ACG using a multi-season occupancy model approach. Results: Wood Thrush occupancy was best described by precipitation in the four locations of the ACG; the probability of occupancy increased with precipitation. The average occupancy of Wood Thrushes varied with vegetation type: open area with shrubs and forest edge (0.69 ± 0.09), secondary forest (0.46 ± 0.1), and old-growth forest (0.61 ± 0.1). Wood Thrush probability of persistence responded partially to changes in precipitation, with an unexpected increase in persistence when the rainfall continued decreasing in the season. Conclusion: Wood Thrush occupancy was best predicted by changes in precipitation considering a larger spatial scale. Its probability of persistence partially varied with precipitation. An increase in persistence closer to Spring migration might be explained by the start of the breeding season of resident birds, potentially reducing territorial conflicts and conserving energy before migration. The long-term protection of wet forests in Northern Costa Rica is of paramount importance for the conservation of Wood Thrushes in their wintering grounds.

Resumen Introducción: El Zorzal del Bosque es un ave migratoria que ha experimentado caídas dramáticas en sus poblaciones en las últimas décadas. Esta especie pasa el invierno en fragmentos de bosque con niveles intermedios de modificación de hábitat en Centroamérica. Sin embargo, se necesitan más estudios que detallen el uso de los bosques remanentes a lo largo del tiempo para dilucidar las amenazas que enfrenta esta especie en las zonas de invernada. Objetivo: Comprender los efectos de variables ambientales y de estructura del bosque en la ocurrencia del Zorzal del Bosque en el Norte de Costa Rica. Métodos: El área de estudio fue el Área de Conservación Guanacaste (ACG), ubicada en el Norte de Costa Rica, en diciembre de 2016, y en la temporada migratoria 2018-2019. Estimamos la ocurrencia y la probabilidad de detección del Zorzal del Bosque en cuatro ubicaciones de ACG (bosque seco, bosque nuboso y dos ubicaciones en el bosque húmedo) utilizando modelos de ocurrencia de una sola temporada. También estimamos la ocurrencia del Zorzal del Bosque y la probabilidad de persistencia en diferentes meses en tres tipos de vegetación (área abierta, bosque secundario y bosque primario) en el bosque húmedo de ACG utilizando un enfoque de modelo de ocurrencia multi-estacional. Resultados: La ocurrencia del Zorzal del Bosque estuvo mejor descrita por la precipitación en las cuatro localidades del ACG; la probabilidad de ocurrencia aumentó con las precipitaciones. La ocurrencia media de zorzales varió con el tipo de vegetación: área abierta con arbustos y borde de bosque (0.69 ± 0.09), bosque secundario (0.46 ± 0.1) y bosque primario (0.61 ± 0.1). La probabilidad de persistencia del zorzal respondió parcialmente a cambios en la precipitación, con un aumento inesperado en la persistencia cuando las precipitaciones continuaron disminuyendo en la temporada. Conclusión: La ocurrecia del Zorzal del Bosque varió con la precipitación considerando una escala espacial mayor. Su probabilidad de persistencia varió parcialmente con la precipitación. Un aumento en la persistencia más cerca de la migración de primavera podría explicarse por el inicio de la temporada de reproducción de las aves residentes, lo que podría reducir los conflictos territoriales y conservar energía antes de la migración. La protección a largo plazo de los bosques húmedos en el norte de Costa Rica es de suma importancia para la conservación de los Zorzales del Bosque en sus zonas de invernada.

Exceso de muertes en argentina durante la pandemia por COVID-19: análisis de la mortalidad entre 2020 y 2022 / Excess deaths in Argentina during the COVID-19 pan demic: analysis of mortality between 2020 and 2022

Resumen Los reportes del exceso de mortalidad durante la pandemia por COVID-19 en Argentina han sido parcia les y fragmentados hasta el momento. Este estudio se propuso cuantificar el exceso de muertes y explorar su distribución demográfica, temporal y geográfica durante el periodo 2020-2022. Utilizando datos de 1 192 963 registros de muertes de estadísticas vitales y proyecciones poblacionales, se estimó la mortalidad esperada mediante modelos de regresión. El exceso de muertes se calculó como la diferencia entre la mortalidad observada y la esperada. Se estimó un exceso de 160 676 muertes (IC 95% 146 861 a 174 491), representando una tasa de 116.9 muer tes (IC 95% 115.5 a 118.3) adicionales por cada 100 000 personas-año. Se verificó una significativa heterogenei dad entre las distintas provincias argentinas. Los resultados indican un impacto desigual de la pandemia, con mayores tasas de exceso de mortalidad en algunas regiones y grupos de edad más vulnerables. Estos patrones sugieren la necesidad de estrategias diferenciadas de respuesta sanitaria y apoyo a las poblaciones más vulnerables en escenarios de nuevas epidemias.

Abstract Reports of excess mortality during the COVID-19 pan demic in Argentina have been partial and fragmented so far. This study aimed to quantify excess deaths and explore their demographic, temporal, and geographic distribution during the period 2020-2022. Using data from 1 192 963 death records from vital statistics and population projections, expected mortality was estimated using regression models. Excess death was calculated as the difference between observed and expected mortality. An excess of 160 676 deaths (95% CI 146 861 to 174 491) was estimated, representing a rate of 116.9 (95% CI 115.5 to 118.3) additional deaths per 100 000 person-years. Significant heterogeneity was found among the different argentine provinces. The results indicate an uneven impact of the pan demic, with higher excess mortality rates in some re gions and more vulnerable age groups. These patterns suggest the need for differentiated strategies of health care response and support to the most vulnerable popu lations in scenarios of new epidemics.

Resumen La presión arterial media es un indicador indirecto del grado de perfusión orgánica, la cual podría variar en pacientes con y sin diabetes mellitus-2. El objetivo fue determinar las diferencias y riesgo de alteraciones en la presión arterial media de adultos con y sin diabetes mellitus-2 de la población peruana según datos de la encuesta demográfica de salud familiar. Se realizó un estudio observacional, analítico, retrospectivo y transversal;. Los datos provinieron de la encuesta demográfica y de salud familiar-2022 (ENDES-2022), se incluyó adultos diabéticos y no diabéticos. Las variables fueron: presión arterial media, diabetes mellitus-2, sexo y se incluyeron las variables: edad, consumo de alcohol, nivel educativo e índice de masa corporal para el análisis multivariado. Se realizó la prueba de Chi-cuadrado de Pearson, la prueba T student para muestras independientes, Odds Ratio crudo y ajustado mediante regresión logística binaria. El promedio de presión arterial media en diabéticos fue de 94,81 y 93,52 mmHg en la primera y segunda medición y en no diabéticos de 89,18 y 88,02 mmHg. La presión arterial media alta fue más frecuente en diabéticos que en no diabéticos; En el modelo logístico, incluyendo las variables sexo y edad, los diabéticos tuvieron un riesgo 2 veces mayor que los no diabéticos de alteraciones en la presión arterial media tanto en la primera como en la segunda medición. En conclusión, la diabetes mellitus-2 incrementa la presión arterial media y representa un factor de riesgo para la elevación de la presión arterial media en la población peruana.

Abstract Mean arterial pressure is an indirect indicator of the degree of organ perfusion, which could vary in diabetics and non-diabetics. The objective of this research was to determine the differences and risk of alterations in the mean arterial pressure of adults with and without diabetes mellitus-2 of the Peruvian population according to data from the family health demographic survey. An observational, analytical, retrospective and cross-sectional study was carried out. The data came from the demographic and family health survey-2022 (ENDES-2022). Diabetic and non-diabetic adults were included. The variables were mean arterial pressure, diabetes mellitus-2, sex, and the variables age, alcohol consumption, educational level, and body mass index were included for multivariate analysis. Pearson's Chi-square test, student's T test for independent samples, crude Odds Ratio and adjusted by binary logistic regression were performed. The mean arterial pressure in diabetics was 94.81 and 93.52 mmHg in the first and second measurements, and in non-diabetics it was 89.18 and 88.02 mmHg. High mean arterial pressure was more frequent in diabetics than in non-diabetics. In the logistic model, including the variables sex and age, diabetics had a risk twice as high as non-diabetics for alterations in mean arterial pressure in both the first and second measurements. In conclusion, diabetes mellitus-2 increases mean arterial pressure and represents a risk factor for elevated mean arterial pressure in the Peruvian population.

Experimental animal models in traumatic brain injury research: a comprehensive review of methods and outlook

Traumatic brain injury (TBI) remains a significant public health concern worldwide, necessitating effective research models to elucidate its pathophysiology and develop therapeutic interventions. Animal models play a crucial role in TBI research, offering valuable insights into injury mechanisms and potential treatments. However, selecting the appropriate model can be challenging due to diverse array of available options and their respective advantages and limitations. In this comprehensive review, we examine four commonly used animal models of TBI: the weight drop, fluid percussion, cortical impact, and blast injury models. Each model is characterized by distinct injury mechanisms, allowing researchers simulate various aspects of TBI pathology. We discuss the unique advantages and disadvantages of each model, providing insights into their applications and considerations for model selection based on research objectives and outcome measures. Furthermore, we highlight emerging directions in TBI modelling, emphasizing the importance of refining and innovating models to replicate the complexity of human TBI. By critically evaluating and understanding the subtlety of different TBI models, researchers can make informed decisions to enhance the translational potential of preclinical TBI research and ultimately improve clinical outcomes for TBI patients.

Fasting glucose: a cardiometabolic indicator for subclinical atherosclerosis on excess weight adolescents

Abstract Objective: To build a model based on cardiometabolic indicators that allow the identification of overweight adolescents at higher risk of subclinical atherosclerotic disease (SAD). Methods: Cross-sectional study involving 161 adolescents with a body mass index ≥ + 1 z-Score, aged 10 to 19 years. Carotid intima-media complex thickness (IMT) was evaluated using ultrasound to assess subclinical atherosclerotic disease. Cardiometabolic indicators evaluated included nutritional status, central adiposity, blood pressure, lipidic profile, glycemic profile, as well as age and sex. Data was presented using measures of central tendency and dispersion, as well as absolute and relative frequency. The relationship between IMT measurement (outcome variable) and other variables (independent variables) was assessed using Pearson or Spearman correlation, followed by multiple regression modeling with Gamma distribution to analyze predictors of IMT. Statistical analysis was performed using SPSS and R software, considering a significance level of 5 %. Results: It was observed that 23.7 % had Carotid thickening, and the prevalence of abnormal fasting glucose was the lowest. Age and fasting glucose were identified as predictors of IMT increase, with IMT decreasing with age by approximately 1 % per year and increasing with glucose by around 0.24 % per mg/dL. Conclusion: The adolescent at higher risk is younger with higher fasting glycemia levels.

Aproximación ecológica a las características y factores determinantes de la violencia sexual contra adolescentes en Perú / Ecological approach to the characteristics and determinants of sexual violence against adolescents in Perú

RESUMEN Introducción. La violencia sexual contra los adolescentes es un problema global que afecta a jóvenes de todo el mundo. El modelo ecológico examina sus formas y factores determinantes a través de niveles interconectados. Objetivo. Determinar la frecuencia, las características y los predictores de la violencia sexual contra adolescentes escolarizados en Perú. Materiales y métodos. Se llevó a cabo un estudio transversal en el cual se analizaron de manera secundaria los datos de la Encuesta Nacional de Relaciones Sociales (2019). Una muestra probabilística estratificada incluyó a 1.579 jóvenes de 12 a 17 años de 93 escuelas. Con el cuestionario se evaluó la violencia sexual en la familia y en la escuela. Se estimaron modelos mediante análisis de regresión logística, calculando la razón de momios (odds ratio, OR). Resultados. El 18,68 % (IC95%: 16,80-20,60) sufrió algún tipo de agresión sexual. Además, el 9,75 % (IC95%: 8,28-11,21) informó haber sido tocado en alguna parte del cuerpo y el 1,84 % (IC95%: 1,17-2,50) informó que fue víctima de violación. La edad se identificó como factor de riesgo en el microsistema (OR=1,48) (IC95%: 1,26-1,74), mientras que la edad de la primera violencia sexual actuó como factor protector (OR=0,61) (IC95%: 0,54-0,69). Además, en el macrosistema, la percepción de que la violencia ocurre principalmente fuera del hogar incrementó el riesgo (OR=2,06) (IC95%: 1,01-4,19). Conclusión. Aproximadamente, dos de cada diez encuestados informaron haber experimentado algún tipo de violencia sexual, siendo el acoso verbal y el contacto personal invasivo los más comunes. Ningún nivel del modelo ecológico o factor único puede explicar completamente la violencia sexual contra los adolescentes sin considerar su interconexión ecológica.

ABSTRACT Introduction. Sexual violence against adolescents is a global problem that affects young people around the world. The ecological model examines its forms and determinants through interconnected levels. Objective. To determine the frequency, characteristics, and predictors of sexual violence in adolescents attending school in Perú. Materials and methods. This was a cross-sectional study that secondarily analyzed data from the Encuesta Nacional de Relaciones Sociales (2019). A stratified probabilistic sample involved 1,579 youth aged 12-17 from 93 schools. The questionnaire evaluated physical, psychological, and sexual violence in the family and at school. Models were estimated using logistic regression analysis, calculating odds ratio (OR). Results. Eighteen point sixty eight per cent (95% CI: 16.80-20.60) suffered some type of sexual assault. In addition, 9.75% (95% CI: 8.28-11.21) reported having been touched in some part of the body and 1.84% (95% CI: 1.17-2.50) reported that was a victim of rape. Age was identified as a risk factor in the microsystem (OR = 1.48) (95% CI: 1.26-1.74), while the age of the first experienced sexual violence acted as a protective factor (OR = 0.61) (95% CI: 0.54-0.69). In addition, in the macrosystem, the perception that violence occurs mainly outside the home increased the risk (OR = 2.06) (95% CI: 1.01-4.19). Conclusions. Approximately two out of ten respondents reported having experienced some type of sexual violence, with verbal harassment and invasive personal contact being the most common. No single level or factor can fully explain adolescent sexual violence without considering its ecological interconnectedness.

Introdução: O zumbido é um sintoma de alta prevalência na população, que necessita de cuidado especializado e centrado no paciente e suas individualidades. Objetivo: investigar a rede de cuidado especializado em pacientes com queixa de zumbido no Brasil. Método: Realizou-se uma busca a nível nacional com 152 profissionais que atendem o público com zumbido, por meio de redes sociais, além de utilizar a técnica "snow ball". Foram selecionados os profissionais com atuação clínica ou participação de grupo de pesquisa em zumbido. Aos selecionados, foi enviado por e-mail ou rede social um questionário do Google Forms composto por doze questões objetivas, a fim de identificar o perfil desses profissionais, bem como do atendimento oferecido por eles. Os dados foram categorizados e tabulados em planilha digital para posterior análise estatística descritiva e inferencial. Resultados: os resultados mostraram que há profissionais atuantes em zumbido em 21 estados brasileiros, sendo a maior parte nas regiões Sudeste e Nordeste, inseridos principalmente no setor privado e a maioria em equipes multidisciplinares que contam, pelo menos, com um otorrinolaringologista e um fonoaudiólogo, apresentando práticas avaliativas e terapêuticas semelhantes. Conclusão: foi possível observar que, embora o número de profissionais ainda seja um número reduzido, além de não serem bem distribuídos geograficamente, há uma semelhança quanto aos métodos de avaliação e tratamento utilizados, bem como a abordagem multidisciplinar tem se tornado uma realidade na prática clínica, ainda que mais presente no setor privado, o que renova as perspectivas do público acometido pelo zumbido, para um futuro próximo.

Introduction: Tinnitus is a highly prevalent symptom in the population, which requires specialized care centered on the patient and their individualities. Objective: to investigate the specialized care network for patients complaining of tinnitus in Brazil. Method: A national search was carried out with 152 professionals who serve the public with tinnitus, through social networks, in addition to using the "snowball" technique. Professionals with clinical experience or participation in a tinnitus research group were selected. To those selected a Google Forms questionnaire was sent via email or social media, consisting of twelve objective questions, in order to identify the profile of these professionals, as well as the service they offer. The data were categorized and tabulated in a digital spreadsheet for subsequent descriptive and inferential statistical analysis. Results: the results showed that there are professionals working in tinnitus in 21 Brazilian states, most of them in the Southeast and Northeast regions, mainly in the private sector and the majority in multidisciplinary teams that include at least one otorhinolaryngologist and one speech therapist, presenting similar evaluative and therapeutic practices. Conclusion: it was possible to observe that, although the number of professionals is still small, in addition to not being well distributed geographically, there is a similarity in the evaluation and treatment methods used, as well as the multidisciplinary approach has become a reality in practice clinic, although more present in the private sector, which renews the perspectives of the public affected by tinnitus, for the near future.

Cooperación entre médicos del departamento de emergencias y dermatólogos por telemedicina / Cooperation between emergency department physicians and dermatologists via telemedicine

Las intercurrencias dermatológicas agudas son un motivo de consulta frecuente a las centrales de emergencias, y generalmente los médicos de atención primaria se ocupan del primer nivel de atención. Puede ser necesaria una interconsulta con expertos, aunque no siempre estén disponibles. Ante la necesidad de facilitar dicha interacción a distancia, en Julio 2022 se implementó una herramienta de teledermatología en un hospital de alta complejidad en Buenos Aires, Argentina. Este servicio se limitó a días hábiles con horario restringido, permitiendo la comunicación entre médicos del departamento de emergencias y dermatólogos, a través de WhatsApp institucional. El dermatólogo podía verificar datos de salud relacionados al paciente (ej: comorbilidades y medicación crónica) mediante revisión de la historia clínica electrónica, para decidir sobre un plan de acción. Se evaluó la perspectiva de los usuarios a través de un formulario electrónico tras 3 meses de implementación. Los resultados evidenciaron que la mayoría (85%) de los profesionales conocía la herramienta, y el 57% la había usado al menos una vez. Se obtuvo una mediana de 9 puntos (de una escala de Likert del 1 al 10) sobre la recomendación hacia otro profesional. El teletriage dermatológico resultó beneficioso y fue aceptado, tanto por médicos de guardia como por especialistas. Ante las demoras en la atención ambulatoria, ha resultado una alternativa útil para evitar derivaciones innecesarias y/o acelerar aquellas que verdaderamente lo ameritan. Sin embargo, representa una forma de comunicación informal desde el punto de vista de almacenamiento de datos. Será necesario reflexionar sobre estos tópicos pendientes de esta experiencia asistencial como legalidad, seguridad y confidencialidad (AU)

Acute skin conditions are a frequent reason for consultation in emergency departments, and primary care physicians generally handle them. They might require referrals to experts, who are not always readily available. Recognizing the need to facilitate such interactions remotely, a teledermatology triage tool was implemented in July 2022 at a high-complexity hospital in Buenos Aires, Argentina. The service was limited to business days with restricted hours, enabling communication between emergency department physicians and dermatologists through institutional WhatsApp. Dermatologists could access patient-related health data (e.g., comorbidities and chronic medication) through the electronic medical record to determine an appropriate course of action. The perspective of users was evaluated through an electronic questionnaire after three months of application. Results showed that most professionals were aware of the tool (85%), and 57% used it at least once. The median rating for recommending the tool to other professionals was 9 points (on a Likert scale from 1 to 10). Dermatological teletriage proved beneficial and was well-received by emergency physicians and specialists. In the face of delays in outpatient care, it has been a useful alternative to avoid unnecessary referrals and expedite those that are warranted. However, it represents an informal method of communication with regard to data storage. It will be necessary to rethink on improvements in pending topics such as legal limitations, security, and confidentiality of this healthcare experience (AU)

Body Practices and Physical Activity Interventions in Primary Health Care: an Integrative Review / Intervenções de Práticas Corporais e Atividade Física na Atenção Primária à Saúde: uma Revisão Integrativa

In recent decades, body practices and physical activities (PCAF) have become part of the public health agenda. Actions to combat sedentary lifestyle in primary care are developed through body practices, physical exercises, physical activities and guided walks. The main objective of this study is to verify which interventions are being carried out by the Physical Education Professional (PEF) in primary care. This study comprises an integrative review. After consulting the databases and applying the search strategies, studies that were duplicated between the databases were identified and excluded. To compose this study, 7 articles were selected. With regard to the types of exercises found in the articles, 3 studies performed only resistance exercise, in which it was the Pilates method and Chinese gymnastics Liang Gong. Still, 4 studies combined aerobic and resistance exercises. Other important findings of this study, that the elderly population are the ones that most participated in the interventions and that the interventions were concentrated in the South and Southeast regions. In the interventions portrayed in this review, the diversification of physical exercises offered in Primary Care was noticed. All interventions brought positive health benefits at the physiological, social and/or psychological levels. This fits into the perspective of health promotion among the population that performs physical activity and/or physical exercise in Primary Care programs. (AU)

Nas últimas décadas as práticas corporais e atividades físicas (PCAF) passaram a compor a agenda da saúde pública. As ações para aumentar a prática de atividade física na Atenção Primária, são orientadas e desenvolvidas por meio de práticas corporais, exercícios físicos, atividades físicas e caminhadas. O presente estudo tem como objetivo principal verificar quais intervenções realizadas pelo Profissional de Educação Física (PEF) na Atenção Primária à Saúde. Este estudo compreende uma revisão integrativa. Após a consulta às bases de dados e a aplicação das estratégias de busca, foram identificados e excluídos estudos que apresentavam duplicidade entre as bases e foram selecionados sete artigos para compor este estudo. No que se refere aos tipos de exercícios físicos encontrados nos artigos, o exercício Resistance foi o mais prevalente (OU utilizado) nas intervenções, seguido pelas práticas integrativas e exercícios aeróbicos. Outros achados importantes neste estudo, foi a maior participação da população idosa nas intervenções, concentradas nas regiões do Sul e Sudeste. Nas intervenções retratadas nesta revisão percebeu-se a diversificação dos exercícios físicos oferecidos na Atenção Básica. Todas as intervenções trouxeram benefícios positivos para a saúde, nos níveis fisiológicos, sociais e/ou psicológicos, bem como o ponto de maior destaque foi a utilização do exercício Resistance. O que se enquadra numa perspectiva de promoção da saúde junto à população que realiza atividade física e/ou exercício físico nos programas da Atenção Primária à Saúde. (AU)

Panorama histórico dos modelos de atenção e políticas de saúde bucal no Brasil: uma revisão de literatura / Historical overview of oral health care models and policies in Brazil: a literature review

Objetivo: Descrever aos contextos históricos relacionados aos modelos de assistência e políticas de saúde bucal no Brasil, analisando seus impactos, avanços e desafios. Revisão de literatura: As trajetórias das políticas de saúde bucal no Brasil foram caracterizadas por iniciativas limitadas e centradas no tratamento curativo, evoluindo gradualmente para um sistema de saúde mais inclusivo e voltado para a prevenção ao longo dos anos. Historicamente, o sistema público de saúde brasileiro enfrentou desafios consideráveis para garantir o acesso universal aos serviços odontológicos. Discussão: Questões como a falta de acesso e uma abordagem predominantemente voltada para o controle de doenças, como demonstrado pelos modelos assistenciais Incremental e Integral, bem como problemas de infraestrutura e insuficiência de financiamento adequado, foram amplamente discutidos. Com o advento da reforma sanitária, a realização da 8ª Conferência Nacional de Saúde e a promulgação da Constituição Federal de 1988, seguida pela criação do Sistema Único de Saúde (SUS), buscou-se estabelecer um modelo de atenção à saúde com foco na prevenção, integralidade e universalidade. Posteriormente ficou estabelecida a Política Nacional de Saúde Bucal em 2004, e no ano de 2023 o Projeto de Lei nº 8.131/17 que efetivamente incluiu a saúde bucal no escopo de atuação do SUS. Conclusão: Embora os resultados observados na primeira década do século XXI indiquem melhorias no acesso aos serviços de saúde bucal, a literatura aponta para desafios a serem enfrentados, particularmente em relação à garantia de acesso equitativo aos serviços odontológicos em todo o país.

Aim: To describe the historical contexts related to oral health care models and policies in Brazil, analyzing their impacts, progress, and challenges. Literature review: The trajectories of oral health policies in Brazil have been characterized by limited initiatives focused on curative treatment, gradually evolving into a more inclusive health system with a preventive focus over the years. Historically, the Brazilian public health system has faced considerable challenges in ensuring universal access to dental services. Discussion:Issues such as lack of access and a predominantly disease-focused approach, as demonstrated by the Incremental and Integral care models, as well as infrastructure problems and insufficient funding, have been widely discussed. With the advent of health reform, the 8th National Health Conference, and the promulgation of the Federal Constitution of 1988, followed by the creation of the Unified Health System (SUS), efforts were made to establish a health care model with a focus on prevention, comprehensiveness, and universality. Subsequently, the National Oral Health Policy was established in 2004, and in 2023, Bill No. 8,131/17 was enacted, effectively including oral health in the scope of SUS activities. Conclusion:Although the results observed in the first decade of the 21st century indicate improvements in access to oral health services, the literature points to challenges to be faced, particularly in ensuring equitable access to dental services nationwide.

Artificial intelligence ChatGPT in ophthalmology and scientific writing / 国际眼科杂志(Guoji Yanke Zazhi)

ChatGPT is a large language models(LLMs)that uses deep learning techniques to produce human-like responses to natural language inputs. It belongs to the family of generative pre-training transformer(GPT)models currently publicly available developed by OpenAI in November 2022. ChatGPT is capable of capturing the nuances and intricacies of human language, generating appropriate and contextually relevant responses. It can assist medical professionals in various tasks, such as research, diagnosis, patient monitoring, and medical education, from identifying research programs to assisting in clinical and laboratory diagnosis, to know new developments in their fields and scientific writing. ChatGPT has also attracted increasing attention and widely used in ophthalmology. However, the use of ChatGPT and other artificial intelligence tools in such tasks comes now with several limitations, ethical and legal concerns, such as credibility, plagiarism, copyright infringement, and biases. Future research can focus on developing new methods to mitigate these limitations while harnessing the benefits of ChatGPT in medicine and related aspects.

Effect of ADU-S100/doxorubicin in situ vaccine on diffuse large B-cell lymphoma and its mechanism / 白血病·淋巴瘤

Objective:To explore the antitumor effect of ADU-S100/doxorubicin in situ vaccine on diffuse large B-cell lymphoma (DLBCL) and its mechanism.Methods:The 6-week-old female BALB/c mice were selected, and the bilateral murine subcutaneous B-cell lymphoma model was established with murine B-cell lymphoma A20 cells. The subcutaneous tumor-bearing mice were randomly divided into untreated group (without treatment), ADU-S100 in situ vaccine treatment group (intratumoral injection of interferon gene stimulating factor agonist ADU-S100), doxorubicin in situ vaccine treatment group (intratumoral injection of doxorubicin), and ADU-S100/doxorubicin in situ vaccine treatment group (intratumoral injection of ADU-S100 and doxorubicin) by using random number table method, with 5 mice in each group. The right tumors of the bilateral subcutaneous tumor-bearing mice were defined as proximal tumors, and the left tumors of the bilateral subcutaneous tumor-bearing mice were defined as distal tumors. Only the proximal tumors were treated via the intratumoral route, and the distal tumors were not treated. On day 23 after tumor inoculation, the percentages of CD11c + dendritic cells (DC), CD8 + CD11c + DC and CD80 + CD11c + DC in the spleen of mice in each group were detected by flow cytometry. The splenocytes of mice in each group were stimulated with A20 tumor cell lysate in vitro, the percentages of 5'-ethynyl-2'-deoxyuridine-positive (EdU +) cells and tumor necrosis factor-α-positive (TNF-α +) cells in CD8 + T cells in each in situ vaccine treatment group were detected by flow cytometry, and the killing effect of cytotoxic T lymphocyte (CTL) in each group was measured by using the lactate dehydrogenase (LDH) cytotoxicity assay kit. The mice treated with ADU-S100/doxorubicin in situ vaccine were intraperitoneally injected with anti-mouse CD8α (clone 53-6.7) mAb or isotype control on days 7, 12 and 17 after tumor inoculation to eliminate CD8 + cells. On day 23 after tumor inoculation, the proximal and distal tumor volumes of mice in the ADU-S100/doxorubicin in situ vaccine combined with anti-mouse CD8α (clone 53-6.7) mAb or isotype control treatment group were measured, the percentages of CD8 + T cells and CD8 + CD11c + DC in the spleen of tumor-bearing mice in these two groups were detected by flow cytometry, and the infiltration of CD8 + T cells in the tumor tissues from these two groups was detected by immunohistochemistry (IHC) staining. Results:On days 11, 14, 17, 20 and 23 after tumor inoculation, the proximal and distal tumor volumes of mice in each treated group were lower than those in the untreated group (all P < 0.05). The proportions of CD11c + DC in the spleen of the untreated group, ADU-S100 in situ vaccine treatment group, doxorubicin in situ vaccine treatment group and ADU-S100/doxorubicin in situ vaccine treatment group were (4.92±0.63)%, (7.54±0.84)%, (7.45±0.86)% and (11.63±0.85)%, respectively, and the difference was statistically significant ( F = 72.30, P < 0.001); the proportions of CD8 + CD11c + DC were (1.36±0.34)%, (4.02±0.43)%, (4.22±0.61)% and (6.11±0.73)%, respectively, and the difference was statistically significant ( F = 76.09, P < 0.001); the proportions of CD80 + CD11c + DC were (0.51±0.24)%, (1.69±0.23)%, (1.82±0.25)% and (4.09±0.39)%, respectively, and the difference was statistically significant ( F = 167.40, P < 0.001). The CTL responses and the proportion of EdU + cells and TNF-α + cells in CD8 + T cells in each in situ vaccine treatment group were higher than those in the untreated group (all P < 0.05). Furthermore, the enhanced CTL responses and the increased proportion of EdU + cells and TNF-α + cells in CD8 + T cells were observed in the ADU-S100/doxorubicin in situ vaccine treatment group as compared to the ADU-S100 in situ vaccine treatment group and doxorubicin in situ vaccine treatment group (all P < 0.05). The proportions of CD8 + T cells and CD8 + CD11c + DC in the spleen of mice treated with ADU-S100/doxorubicin in situ vaccine and anti-mouse CD8α mAb were lower than those in ADU-S100/doxorubicin in situ vaccine and isotype control group (both P < 0.05) and both proximal and distal tumor volumes of mice treated with ADU-S100/doxorubicin in situ vaccine and anti-mouse CD8α mAb were larger than those in ADU-S100/doxorubicin in situ vaccine and isotype control group (both P < 0.05). Conclusions:ADU-S100/doxorubicin in situ vaccine can induce profound regression of proximal tumors in bilateral murine subcutaneous B-cell lymphoma model and generate systemic immune responses capable of partially inhibiting distant tumor growth, and the antitumor efficacy of ADU-S100/doxorubicin in situ vaccine may require CD8 + CD11c + DC-mediated CD8 + T cell immune responses.
