RESUMO

BACKGROUND: The description of local seasonality patterns in respiratory syncytial virus (RSV) incidence is important to guide the timing of administration of RSV immunization products. METHODS: We characterized RSV seasonality in Guatemala using the moving epidemic method (MEM) with absolute counts of RSV-associated acute respiratory infections (ARI) from hospital surveillance in Santa Rosa and Quetzaltenango departments of Guatemala. RESULTS: From Week 17 of 2008 through Week 16 of 2018, 8487 ARI cases tested positive for RSV by rRT-PCR. Season onsets varied up to 5 months; early seasons starting in late May to early August and finishing in September to November were most common, but late seasons starting in October to November and finishing in March to April were also observed. Both epidemic patterns had similar durations ranging from 4 to 6 months. Epidemic thresholds (the levels of virus activity that signal the onset and end of a seasonal epidemic) calculated prospectively using previous seasons' data captured between 70% and 99% of annual RSV detections. Onset weeks differed by 2-10 weeks, and offset weeks differed by 2-16 weeks between the two surveillance sites. CONCLUSIONS: Variability in the timing of seasonal RSV epidemics in Guatemala demonstrates the difficulty in precisely predicting the timing of seasonal RSV epidemics based on onset weeks from past seasons and suggests that maximal reduction in RSV disease burden would be achieved through year-round vaccination and immunoprophylaxis administration to at-risk infants.

RESUMO

RESUMEN Introducción: Dada la existencia de variadas guías para enfermedades respiratorias, se buscó conocer cuáles eligen los médicos para utilizar en su práctica clínica. Materiales y Métodos: se realizó un estudio descriptivo, transversal, mediante una encuesta a neumonólogos de la Asociación Argentina de Medicina Respiratoria. Resultados: La guía más utilizada para EPOC fue la Iniciativa Global para la Enferme dad Pulmonar Obstructiva Crónica (GOLD) (82 %), seguida por GesEPOC (51 %). Para asma las más usadas fueron la Iniciativa Global para el Asma (GINA) 2022 (89 %) y GEMA 5.2 (68 %). En asma de difícil control, se prefirieron GINA 2022 (82 %) y GEMA 2022 (53 %). En espirometría, un 54 % de los respondedores se inclinó por NHANES III y un 22 % utilizó valores teóricos de referencia de Knudson. En neumonía, el 62 % eligió SADI, el 37 %, IDSA y el 20 %, BTS. Para nódulos pulmonares, el 62 % prefirió las guías Fleischner, 35 % se inclinó por Lung-RADS 1.1. Para neumonitis por hip ersensibilidad, un 83 % seleccionó las guías de las sociedades conjuntas ATS/JRS/ ALAT. Para imágenes de fibrosis pulmonar, el 89 % utilizó ALAT/ERS/JRS/ALAT y el 18 % White Paper. Discusión: si bien hay estudios sobre adherencia a guías, no los hay acerca de pref erencias de utilización entre varias referidas a un mismo tema. En EPOC y asma (in cluyendo la de difícil control) se eligieron GOLD y GINA y las de la Sociedad Española de Patología Respiratoria (GesEPOC y GEMA). El uso preferencial de la guía nacional para neumonía es coherente con la necesidad de contemplar la epidemiología local.

ABSTRACT Introduction: Since there are various guidelines for respiratory diseases, we aimed to know which are chosen by physicians in their daily clinical practice. Materials and Methods: A descriptive, cross-sectional study was conducted through a questionnaire sent to pulmonologists of the Argentinian Association of Respiratory Medicine. Results: The most commonly used guideline for COPD (chronic obstructive pulmonary disease) was the Global Initiative for Chronic Obstructive Lung Disease (GOLD) (82 %), followed by GesEPOC (51 %). For asthma, the most commonly used guideline was the Global Initiative for Asthma (GINA) 2022 (89 %) and the Spanish Guideline on the Management of Asthma (known for its acronym in Spanish, GEMA), GEMA 5.2 (68 %). In difficult-to-control asthma, GINA 2022 (82 %) and GEMA 2022 (53 %) were used. With regard to spirometries, 54 % of respondents favored NHANES III (Third National Health and Nutrition Examination Survey) and 22 % used theoretical Knudson reference values. For pneumonia, 62 % chose the guidelines of the SADI (Argentinian Society of Infectious Diseases), 37 % preferred those of the IDSA (Infectious Diseases Society of America) and 20 %, chose the guidelines of the BTS (British Thoracic Society). For pulmonary nodules, 62 % used Fleischner guidelines, and 35 % favored Lung-RADS 1.1. For hypersensitivity pneumonitis, 83 % selected the ATS/JRS/ALAT Guidelines (American Thoracic Society/Japanese Respiratory Society/Latin American Thoracic Society). And with respect to pulmonary fibrosis imaging, 89 % used ALAT/ERS (Eu ropean Respiratory Society)/JRS recommendations, and 18 % preferred White Paper. Discussion: Although there are studies about adherence to guidelines, none of them shows which are the chosen recommendations within a group of guidelines of the same topic. In COPD and asthma (including difficult-to-control asthma) GOLD, GINA and the guidelines of the Spanish Society of Respiratory Disease (GesEPOC and GEMA) were chosen. The preference for the national guideline for pneumonia is consistent with the need to consider local epidemiology.

RESUMO

ABSTRACT Objective: Cystic fibrosis (CF) affects multiple organs, the most severe consequences being observed in the lungs. Despite significant progress in developing CF transmembrane conductance regulator-specific treatments for CF lung disease, exploring alternative CF-targeted medications seems reasonable. We sought to evaluate the potential beneficial effects of oral benzbromarone as an adjuvant therapy in CF patients with reduced lung function. Methods: This was a prospective open-label pilot study of oral benzbromarone (100 mg/day) administered once daily for 90 days. Patients were followed at a tertiary referral center in southern Brazil. Safety was assessed by the number of reported adverse events. Secondary objectives included percent predicted FEV1 (FEV1%) and pulmonary exacerbations. Results: Ten patients were enrolled. Benzbromarone was found to be safe, with no serious drug-related adverse events. Eight patients completed the study; the median relative change in FEV1% tended to increase during the treatment, showing an 8% increase from baseline at the final visit. However, a nonparametric test showed that the change was not significant (p = 0.06). Of a total of ten patients, only one experienced at least one pulmonary exacerbation during the study. Conclusions: Oral benzbromarone appears to be safe, and improved FEV1% has been observed in patients with CF. Further assessment in larger trials is warranted to elucidate whether oral benzbromarone can be a potential adjuvant therapy for CF.

RESUMO

Resumen: El artículo muestra el impacto directo e indirecto del COVID-19 en la esperanza de vida de Chile durante el año 2020, utilizando las estadísticas de defunciones definitivas publicadas en marzo del año 2023. Para ello, se estimó una mortalidad contrafactual para año 2020 sin el COVID-19, siguiendo el patrón de mortalidad según causas de muerte desde 1997 a 2019, se elaboraron tablas de mortalidad para calcular la esperanza de vida para los años 2015 a 2020 y para el año 2020 estimado, y luego se descompuso la diferencia entre la esperanza de vida esperada y observada del año 2020 según grupos de edad y causas de muerte. La esperanza de vida del año 2020 quiebra la tendencia a su aumento entre 2015 y 2019, mostrando un retroceso, en hombres y en mujeres, con respecto al año 2019, de 1,32 y 0,75 años respectivamente. Con respecto al año 2020 estimado, la esperanza de vida del 2020 observado es 1,51 años menor en hombres y 0,92 en mujeres, pero el impacto directo del COVID-19 en pérdida de esperanza de vida fue mayor, 1,89 para los hombres y 1,5 para las mujeres, concentrándose en las edades entre los 60 y 84 años en hombres y entre 60 y 89 años en mujeres. El impacto directo negativo del COVID-19 a la esperanza de vida en parte fue contrarrestado por impactos indirectos positivos significativos en dos grupos de causas de muerte, las enfermedades del sistema respiratorio y las enfermedades infecciosas y parasitarias. El estudio muestra la necesidad de distinguir los impactos directos e indirectos del COVID-19, por la incidencia que pueden tener en la salud pública cuando el COVID-19 baje su intensidad y se eliminen las restricciones de movilidad.

Abstract: This article shows the direct and indirect impacts of COVID-19 on life expectancy in Chile in 2020, based on mortality statistics published in March 2023. To this end, a counterfactual mortality was estimated for 2020 without COVID-19; based on the pattern of mortality by cause of death from 1997 to 2019, mortality charts were created to calculate life expectancy from 2015 to 2020 and an estimation for 2020, and the difference between expected and observed life expectancy in 2020 was then separated by age group and cause of death. Life expectancy in 2020 interrupted the upward trend from 2015 to 2019, showing a decline of 1.32 years in men and 0.75 years in women compared to 2019. Compared to the estimated 2020, life expectancy was 1.51 years lower in men and 0.92 years lower in women, but the direct impact of COVID-19 on the decrease in life expectancy was greater (1.89 for men and 1.5 for women) in the 60-84 age group in men and the 60-89 age group in women. The direct negative impact of COVID-19 on life expectancy was partially mitigated by significant positive indirect impacts on two groups of causes of death: diseases of the respiratory system and infectious and parasitic diseases. This study shows the need to differentiate direct and indirect impacts of COVID-19, due to the implications for public health when the intensity of COVID-19 decreases and mobility restrictions are suspended.

Resumo: Este artigo apresenta os impactos direto e indireto da COVID-19 na expectativa de vida no Chile em 2020 a partir de estatísticas de mortalidade publicadas em março de 2023. Para tanto, foi estimada uma mortalidade contrafactual para 2020 sem a COVID-19; a partir do padrão de mortalidade por causa de morte de 1997 a 2019, foram criadas tabelas de mortalidade para calcular a expectativa de vida para o período de 2015 a 2020 e para o ano estimado de 2020 e, em seguida, a diferença entre a expectativa de vida esperada e observada em 2020 foi separada por faixa etária e causa de morte. A expectativa de vida em 2020 interrompe a tendência de aumento entre 2015 e 2019, mostrando um declínio com relação a 2019 de 1,32 ano nos homens e 0,75 ano nas mulheres. Com relação ao ano estimado de 2020, a expectativa de vida observada é 1,51 ano menor nos homens e 0,92 nas mulheres, mas o impacto direto da COVID-19 na diminuição da expectativa de vida foi maior (1,89 para homens e 1,5 para mulheres), concentrando-se nas idades entre 60 e 84 anos nos homens e entre 60 e 89 anos nas mulheres. O impacto direto negativo da COVID-19 na expectativa de vida foi parcialmente atenuado por impactos indiretos positivos significativos em dois grupos de causas de morte: doenças do sistema respiratório e doenças infecciosas e parasitárias. Este estudo mostra a necessidade de diferenciar impactos diretos e indiretos da COVID-19, devido às implicações para a saúde pública quando a intensidade da COVID-19 diminuir e as restrições de mobilidade forem suspensas.

RESUMO

Este estudo teve como objetivo investigar a ocorrência de afecções respiratórias em crianças expostas à poeira de resíduos de mineração após o desastre do rompimento da barragem em Brumadinho, Minas Gerais, Brasil. A população de estudo incluiu crianças com idades entre 0 e 6 anos, residentes em três comunidades expostas à resíduos de poeira de mineração (Córrego do Feijão, Parque da Cachoeira e Tejuco) e uma comunidade não exposta (Aranha). A coleta de dados ocorreu entre 19 e 30 de julho de 2021, por meio de questionários que abordavam informações sociodemográficas e um inquérito recordatório sobre sinais, sintomas e doenças respiratórias. Foram avaliadas 217 crianças, sendo 119 das comunidades expostas e 98 da comunidade não exposta. Os residentes nas comunidades expostas relataram aumento na frequência de faxina em suas residências (p = 0,04) e no tráfego de veículos (p = 0,03). Entre as crianças de 4 anos, foi observada uma maior frequência de afecções das vias aéreas superiores (p = 0,01) e inferiores (p = 0,01), bem como de alergia respiratória (p = 0,05). O grupo exposto apresentou 1,5 vez mais relatos de alergia respiratória (75%; p = 0,02) em comparação com o não exposto (50,5%). Crianças que viviam nas comunidades expostas à poeira de resíduos apresentaram três vezes mais chance (OR ajustada = 3.63; IC95%: 1,37; 9,57) de ocorrência de alergia respiratória em comparação com as não expostas. Dois anos e seis meses após a ocorrência do desastre ambiental, as crianças das comunidades afetadas pelos resíduos das atividades de mineração e remediação permaneciam expostas à poeira com efeitos tóxicos sobre a saúde respiratória.

This study aimed to investigate the occurrence of respiratory diseases in children exposed to dust from mining waste after the Brumadinho dam disaster, Minas Gerais State, Brazil. The study population included children aged 0-6 years, living in three communities exposed to mining waste dust (Córrego do Feijão, Parque da Cachoeira, and Tejuco) and one unexposed community (Aranha). Data were collected from July 19 to 30, 2021, using questionnaires that addressed sociodemographic information and a recall survey on signs, symptoms, and respiratory diseases. A total of 217 children were evaluated, 119 living in the exposed communities and 98 in the non-exposed community. The residents in the exposed communities reported an increase in the frequency of home cleaning (p = 0.04) and in vehicular traffic (p = 0.03). Among children aged four, a higher frequency of upper (p = 0.01) and lower (p = 0.01) airway disorders, as well as respiratory allergy (p = 0.05) was observed. The exposed group had 1.5 times more reports of respiratory allergy (75%; p = 0.02) compared to the non-exposed group (50.5%). Children living in communities exposed to waste dust were three times more likely (adjusted OR = 3.63; 95%CI: 1.37; 9.57) to have respiratory allergies than those not exposed. Two years and six months after the environmental disaster occurred, children living in the communities affected by waste from mining and remediation activities remained exposed to dust with harmful effects on respiratory health.

El objetivo de este estudio fue investigar la ocurrencia de enfermedades respiratorias en niños expuestos al polvo de residuos de la minería tras el desastre del colapso de la represa en Brumadinho, Minas Gerais, Brasil. La población de estudio incluyó niños que tenían entre 0 y 6 años, que viven en tres comunidades expuestas a residuos de polvo de la minería (Córrego do Feijão, Parque da Cachoeira y Tejuco) y una comunidad no expuesta (Aranha). Se recolectaron los datos entre el 19 y el 30 de julio de 2021, a través de cuestionarios que abordaban informaciones sociodemográficas y una encuesta recordatoria acerca de los señales, síntomas y enfermedades respiratorias. Se evaluaron 217 niños, de los cuales 119 viven en las comunidades expuestas y 98 viven en la comunidad no expuesta. Los residentes de las comunidades expuestas relataron un aumento en la frecuencia de limpieza de sus casas (p = 0,04) y en el tráfico de vehículos (p = 0,03). Entre los niños de 4 años, se observó una frecuencia más alta de enfermedades de las vías aéreas superiores (p = 0,01) e inferiores (p = 0,01), así como de alergia respiratoria (p = 0,05). El grupo expuesto presentó 1,5 veces más relatos de alergia respiratoria (el 75%; p = 0,02) en comparación con el grupo no expuesto (el 50,5%). Niños que vivían en las comunidades expuestas al polvo de residuos presentaron tres veces más probabilidad (OR ajustada = 3,63; IC95%: 1,37; 9,57) de ocurrencia de alergia respiratoria en comparación con los niños que no se expusieron. Dos años y seis meses tras el desastre ambiental, los niños que viven en las comunidades afectadas por los residuos de las actividades de minería y descontaminación permanecían expuestos al polvo con efectos tóxicos para la salud respiratoria.

RESUMO

ABSTRACT Objective: To evaluate the combined impact of videofluoroscopic swallow study (VFSS) and therapeutic feeding and swallowing interventions on clinical outcomes in children with oropharyngeal dysphagia (OPD). Methods: This was an uncontrolled longitudinal analytical study in which OPD patients were evaluated before and after VFSS. Children ≤ 24 months of age diagnosed with OPD in a clinical setting and undergoing VFSS for investigation and management of OPD were included in the study. The study participants received therapeutic feeding and swallowing interventions after having undergone VFSS, being followed at an outpatient clinic for pediatric dysphagia in order to monitor feeding and swallowing difficulties. Respiratory and feeding outcomes were compared before and after VFSS. Results: Penetration/aspiration events were observed in 61% of the VFSSs (n = 72), and therapeutic feeding and swallowing interventions were recommended for 97% of the study participants. After the VFSS, there was a reduction in the odds of receiving antibiotic therapy (OR = 0.007) and in the duration of antibiotic therapy (p = 0.014), as well as in the odds of being admitted to hospital (p = 0.024) and in the length of hospital stay (p = 0.025). A combination of oral and enteral feeding became more common than oral or enteral feeding alone (p = 0.002). Conclusions: A high proportion of participants exhibited penetration/aspiration on VFSS. Therapeutic feeding and swallowing interventions following a VFSS appear to be associated with reduced respiratory morbidity in this population.

RESUMO Objetivo: Avaliar o impacto conjunto da videofluoroscopia da deglutição (VFD) e intervenções terapêuticas de alimentação e deglutição nos desfechos clínicos em crianças com disfagia orofaríngea (DOF). Métodos: Trata-se de um estudo analítico longitudinal não controlado em que pacientes com DOF foram avaliados antes e depois da VFD. Foram incluídas no estudo crianças com idade ≤ 24 meses e diagnóstico clínico de DOF, submetidas à VFD para a investigação e manejo da DOF. Os participantes do estudo receberam intervenções terapêuticas de alimentação e deglutição após terem sido submetidos à VFD, sendo então acompanhados em um ambulatório de disfagia pediátrica para o monitoramento das dificuldades de alimentação e deglutição. Os desfechos respiratórios e alimentares foram comparados antes e depois da VFD. Resultados: Eventos de penetração/aspiração foram observados em 61% das VFD (n = 72), e intervenções terapêuticas de alimentação e deglutição foram recomendadas a 97% dos participantes do estudo. Após a VFD, houve uma redução das chances de receber antibioticoterapia (OR = 0,007) e da duração da antibioticoterapia (p = 0,014), bem como das chances de internação hospitalar (p = 0,024) e do tempo de internação (p = 0,025). A alimentação por via oral e enteral em conjunto tornou-se mais comum do que a alimentação exclusivamente por via oral ou enteral (p = 0,002). Conclusões: Houve alta proporção de crianças que apresentaram penetração/aspiração na VFD. As intervenções terapêuticas de alimentação e deglutição após a VFD parecem estar associadas à redução da morbidade respiratória nessa população.

RESUMO

Resumen Objetivo: Describir el comportamiento espacial de la contaminación por cenizas volcánicas y el efecto sobre la incidencia de enfermedades respiratorias agudas y crónicas, en las comunidades expuestas a la ceniza producida por la actividad del Volcán Turrialba, durante el año 2016. Materiales y métodos: Se realizó un estudio ecológico, observacional retrospectivo, transversal y correlacional, en donde se categorizaron 36 cantones a 50 km a la redonda del volcán Turrialba, según su nivel de contaminación. Resultados: Se constata un comportamiento diferenciado en el espacio geográfico de afectación de la pluma de ceniza volcánica, todos los territorios incluidos en el estudio resultaron con algún nivel de contaminación, sin embargo, se distinguen tres zonas, alta, media y baja contaminación. Un 46.6% de los eventos epidemiológicos estudiados poseen un mayor riesgo de presentarse en cantones con alta contaminación, sobre los cantones con media y baja contaminación. Conclusiones: Es posible que la afectación por contaminación debido a la ceniza volcánica haya incrementado el riesgo de exacerbación de enfermedades respiratorias crónicas, en la zona bajo la influencia directa de la pluma de cenizas volcánicas.

Abstract Objective: Describe the spatial behavior of contamination by volcanic ash and the effect on the incidence of acute and chronic respiratory diseases in communities exposed to the ash produced by the activity of the Turrialba Volcano during the year 2016. Materials and methods: An ecological, observational, retrospective, cross-sectional and correlational study was carried out, where 36 cantons within 50 km of the Turrialba volcano were categorized, according to their level of contamination. Results: A differentiated behavior is verified in the geographical space affected by the volcanic ash plume, all the territories included in the study resulted in some level of contamination, however three zones are distinguished, high, medium and low contamination. 46.6% of the epidemiological events studied have a higher risk of occurring in cantons with high contamination, over cantons with medium and low contamination. Conclusions: It is possible that the contamination due to volcanic ash has increased the risk of exacerbation of chronic respiratory diseases in the area under the direct influence of the volcanic ash plume.

RESUMO

Background: The World Health Organization (WHO) reports an increasing unjustified use of antibiotics in the treatment of Acute Respiratory Infections (ARI) and Acute Diarrheal Diseases (ADD) in children under five years of age. This has generated problems such as polypharmacy and the inappropriate use of antibiotics; characterized by incorrect dosage, use in viral infections, prescription inconsistent with clinical guidelines. Objective: To analyze the prescription of antibiotics, their diagnostic-therapeutic congruence, as well as the correct filling of the medical prescription, in a tertiary level hospital in Mexico. Material and methods: Observational, descriptive cross-sectional study. The electronic medical prescriptions made during the period January-December 2017 with a clinical diagnosis of ARI and EDA were analyzed. Results: Of a total of 21,446 boys and girls under five years of age, 10,233 prescriptions were issued for the treatment of ARI and ADD diagnoses. 80% of the prescriptions complied with the items indicated in the electronic file. Conclusions: The prescription of antibiotics showed a prudent use of antibiotics both in the management of acute diarrheal diseases and in the management of acute respiratory diseases. Diagnostic-therapeutic congruence was found in most of the cases in the prescriptions analyzed.

RESUMO

La desnutrición es una condición caracterizada por la carencia, sobreabundancia o desequilibrio en la ingesta de energía y nutrientes, con efectos significativos en el crecimiento, desarrollo y estatus socioeconómico de las personas, especialmente en madres, bebés y niños. Objetivo. Comparar la asociación entre el estado nutricional y la función pulmonar en niños sin enfermedad respiratoria. Metodología. Se realizó una revisión narrativa de estudios observacionales utilizando bases de datos como Medline (Pubmed), SciELO y Web of Science, empleando un algoritmo de búsqueda que involucró los términos "estado nutricional", "niños" y "enfermedades respiratorias" para posteriomente realizar un análisis crítico entre las dos variables mencionadas en el objetivo a desarrollar en este estudio. Conclusión. Los hallazgos revelaron que la nutrición desempeña un papel fundamental en la salud respiratoria, ya que la desnutrición aumenta el riesgo de infecciones respiratorias, y a su vez, las infecciones pueden llevar a una malnutrición. Además, la desnutrición afecta la función y estructura pulmonar, así como la capacidad del sistema inmunológico para combatir las infecciones. En consecuencia, es crucial asegurar una nutrición adecuada para prevenir y tratar las enfermedades respiratorias en la población infantil.

Malnutrition is a condition characterized by a lack, overabundance or imbalance in energy and nutrient intake, with significant effects on the growth, development and socioeconomic status of individuals, especially mothers, infants and children. Objective. To compare the association between nutritional status and lung function in children without respiratory disease. Methodology. A narrative review of observational studies was carried out using databases such as Medline (Pubmed), SciELO and Web of Science, using a search algorithm that involved the terms "nutritional status", "children" and "respiratory diseases" to subsequently perform a critical analysis between the two variables mentioned in the objective to be developed in this study. Conclusion. The findings revealed that nutrition plays a key role in respiratory health, as malnutrition increases the risk of respiratory infections, and in turn, infections can lead to malnutrition. In addition, malnutrition affects lung function and structure, as well as the immune system's ability to fight infections. Consequently, it is crucial to ensure adequate nutrition to prevent and treat respiratory diseases in the pediatric population.

A subnutrição é uma condição caracterizada pela falta, superabundância ou desequilíbrio na ingestão de energia e nutrientes, com efeitos significativos sobre o crescimento, o desenvolvimento e a situação socioeconômica dos indivíduos, especialmente mães, bebês e crianças. Objetivo. Comparar a associação entre o estado nutricional e a função pulmonar em crianças sem doença respiratória. Metodologia. Foi realizada uma revisão narrativa de estudos observacionais em bases de dados como Medline (Pubmed), SciELO e Web of Science, utilizando um algoritmo de busca envolvendo os termos "estado nutricional", "crianças" e "doenças respiratórias" para, posteriormente, realizar uma análise crítica entre as duas variáveis mencionadas no objetivo a ser desenvolvido neste estudo. Conclusão. Os resultados revelaram que a nutrição desempenha um papel fundamental na saúde respiratória, pois a desnutrição aumenta o risco de infecções respiratórias e, por sua vez, as infecções podem levar à desnutrição. Além disso, a desnutrição afeta a função e a estrutura pulmonar, bem como a capacidade do sistema imunológico de combater infecções. Consequentemente, é fundamental garantir uma nutrição adequada para prevenir e tratar doenças respiratórias na população pediátrica.
