RESUMO Objetivo: Avaliar a sazonalidade da bronquiolite aguda no Brasil durante a temporada 2020–2022 e compará-la com a das temporadas anteriores. Métodos: Os dados de incidência de internações por bronquiolite aguda em lactentes <1 ano de idade foram obtidos do Departamento de Informática da base de dados da Saúde Pública Brasileira para o período entre 2016 e 2022. Esses dados também foram analisados por macrorregiões do Brasil (Norte, Nordeste, Sudeste, Sul e Centro-Oeste). Para descrever características sazonais e de tendência ao longo do tempo, utilizamos o Modelo de Médias Móveis Integradas Autorregressivas Sazonais. Resultados: Em comparação com o período pré-COVID-19, a incidência de hospitalizações relacionadas com bronquiolite aguda diminuiu 97% durante as intervenções não farmacológicas (março de 2020 – agosto de 2021), mas aumentou 95% após a flexibilização das intervenções não farmacológicas (setembro de 2021 – dezembro de 2022), resultando no aumento geral de 16%. Durante o período pré-COVID-19, as hospitalizações por bronquiolite aguda seguiram um padrão sazonal, que foi interrompido em 2020–2021, mas recuperaram-se em 2022, com um pico ocorrido em maio, aproximadamente 4% superior ao pico pré-COVID-19. Conclusões: Este estudo ressalta a influência significativa das intervenções contra a COVID-19 nas hospitalizações por bronquiolite aguda no Brasil. A restauração de um padrão sazonal em 2022 sublinha a interação entre as medidas de saúde pública e a dinâmica das doenças respiratórias em crianças pequenas.

ABSTRACT Objective: To evaluate the seasonality of acute bronchiolitis in Brazil during the 2020–2022 season and compare it with the previous seasons. Methods: Data from the incidence of hospitalizations due to acute bronchiolitis in infants <1 year of age were obtained from the Department of Informatics of the Brazilian Public Health database for the period between 2016 and 2022. These data were also analyzed by macro-regions of Brazil (North, Northeast, Southeast, South, and Midwest). To describe seasonal and trend characteristics over time, we used the Seasonal Autoregressive Integrated Moving Averages Model. Results: Compared to the pre-COVID-19 period, the incidence of hospitalizations related to acute bronchiolitis decreased by 97% during non-pharmacological interventions (March 2020 – August 2021) but increased by 95% after non-pharmacological interventions relaxation (September 2021 – December 2022), resulting in a 16% overall increase. During the pre-COVID-19 period, hospitalizations for acute bronchiolitis followed a seasonal pattern, which was disrupted in 2020–2021 but recovered in 2022, with a peak occurring in May, approximately 4% higher than the pre-COVID-19 peak. Conclusions: This study underscores the significant influence of COVID-19 interventions on acute bronchiolitis hospitalizations in Brazil. The restoration of a seasonal pattern in 2022 highlights the interplay between public health measures and respiratory illness dynamics in young children.

Resumen A pesar de los beneficios bien conocidos de la anestesia raquídea (AR), esta técnica sigue siendo subutilizada entre los anestesiólogos pediátricos. De acuerdo con los datos de la Red Regional de Anestesia Pediátrica, la AR representó menos del 5% de todas las técnicas neuroaxiales. Algunos de los factores a los que se atribuye dicha subutilización son: su duración limitada, la falta de familiaridad con la técnica en niños de menor edad, y la preferencia del anestesiólogo por la anestesia general. El uso seguro y exitoso de la AR en niños implica el claro conocimiento de las diferencias anatómicas y fisiológicas entre adultos y niños, en virtud de las diferencias en las estructuras óseas, el crecimiento de la médula espinal y la fisiología del líquido cefalorraquídeo. Los reportes sobre el uso exitoso de la AR en niños para diferentes cirugías ha aumentado. La presente revisión educativa resumen la información conocida sobre AR en niños, revisiones de la literatura de la última década y ofrece sugerencias para el desarrollo de la AR en población pediátrica. Se discuten consideraciones técnicas, el papel de la ecografía, orientación sobre la dosificación, los efectos fisiológicos, aspectos no explicados del mecanismo de acción y la combinación de anestesia raquídea/caudal.

Abstract Despite the well-known benefits of spinal anesthesia (SA), this technique remains underutilized among pediatric anesthesiologists. According to the data from the Pediatric Regional Anesthesia Network, SA accounted for less than 5% of all neuraxial techniques. Some of the factors for underutilization of SA include: Limited duration, unfamiliarity with the technique in younger children, and surgeon preference for general anesthesia. The safe and successful use of SA in children involves recognition of anatomical and physiological differences between adults and children owing to differences in bony structures, spinal cord growth and cerebrospinal fluid physiology. Reports on successful use of SA in children for various surgeries have increased. This educational review summarizes what is known about SA in children, reviews the literature from the last decade and provides suggestions for development of SA in children. Technical considerations, role of ultrasound, guidance on dosing, physiological effects, unexplained aspects of the mechanism of action and combined caudal/SA are discussed.

Abstract: Christening records were used to determine the levels, evolution and differences between social groups defined by their status in relation to procreation practices outside marriage, as well as the phenomenon of the abandonment of newborns within an urban space: the city of Puebla, during two widely separated decades in the 18th century. The rate of illegitimacy decreased across all social strata over time, with variations according to their position on the social scale. Whether in a more intense urban or peri-urban settings, Spaniards and mestizos had the highest whereas Indigenous people had the lowest rates. The case of Afro-descendants is unique because, despite being a group with more lax customs, they were the least likely to flout the rules at the end of the century. This research contributes to expanding the meaning of illegitimacy and provides comparative elements across time and space in New Spain.

Resumen: En este artículo, con base en el registro de bautismos, se dilucidan los niveles, evolución y diferencias entre los grupos sociales definidos por su calidad en relación con las prácticas de procreación fuera del matrimonio, así como el fenómeno del abandono de recién nacidos dentro de un espacio urbano: la ciudad de Puebla, durante dos décadas distanciadas en el siglo XVIII. Todos los estratos sociales disminuyeron el grado de ilegitimidad en el tiempo, con variaciones de acuerdo con su posición en la escala social. Sea en un hábitat urbano, más intenso, o periurbano, los españoles y mestizos ostentaban las tasas más elevadas, mientras que los indios se ubicaron por abajo. El caso de los afrodescendientes fue singular, pues siendo un conjunto más laxo, fue el menos desafiante de las reglas al concluir la centuria. Esta investigación contribuye a ampliar el significado de la ilegitimidad y provee elementos comparativos en el tiempo y espacio novohispanos.

Abstract The aim of the present study was to analyze the influence of caregivers' verbal production on the lexical production of infants (30 to 48 months), through a joint reading task. Method: 249 dyads (caregiver-infant) participated and the units of analysis type (number of different words produced without repetition) and token (total number of words produced) were used. Statistically significant correlations were observed in all grammatical categories produced by the dyads, as well as the effect of the caregiver's verbal production on that of the infant. The results highlight the importance and influence of caregivers on children's verbal production, with adults' verbal production being a significant predictor of the language development of infants between three and four years of age when interacting in joint reading contexts.

Resumen El objetivo de la presente investigación fue analizar la influencia de la producción verbal de los cuidadores sobre la producción léxica de infantes (30 a 48 meses) mediante una actividad de lectura conjunta. Método: participaron 249 diadas (cuidador-infante) y se utilizaron las unidades de análisis type (número de palabras diferentes producidas sin repetirse) y token (número total de palabras producidas). Se observaron correlaciones estadísticamente significativas en todas las categorías gramaticales producidas por las diadas, así como el efecto de la producción verbal del cuidador sobre la del infante. Los resultados resaltan la importancia e influencia de los cuidadores sobre la producción verbal infantil, siendo la producción verbal de los adultos un predictor significativo del desarrollo de lenguaje de infantes entre tres y cuatro años cuando interactúan en contextos de lectura conjunta.

Abstract Objective To evaluate the growth trajectory of head circumference and neurodevelopment, and to correlate head circumference with cognitive, language, and motor outcomes during the first two years. Method Prospective cohort study in a tertiary hospital including 95 newborns under 32 weeks or 1500 g. Neonates who developed major neonatal morbidities were excluded. The head circumference was measured at birth, at discharge, and at term-equivalent age, 1, 3, 5, 12, 18, and 24 months of corrected age, and the Bayley Scales (Bayley-III) were applied at 12, 18 and 24 months of corrected age to assess cognitive, language and, motor domains. Scores below 85 were classified as mild/moderate deficits and scores below 70 as severe deficits. The association between head circumference Z score and Bayley scores was assessed using Pearson's correlation. The study considered a significance level of 0.05. Results There was a decrease of -0.18 in the head circumference Z score between birth and discharge and the catch-up occurred between discharge and 1 month (an increase of 0.81 in the Z score). There was a positive correlation between head circumference and Bayley scores at 18 months. There was also a positive correlation between head circumference at discharge and at 5 months with the three domains of the Bayley. Conclusion Serial measurements of head circumference provide knowledge of the trajectory of growth, with early catch-up between discharge and 1 month, as well as its association with neurodevelopment. Head circumference is therefore a valuable clinical marker for neurodevelopment, especially in very preterm newborns. neurodevelopment cognitive years 9 3 150 g excluded termequivalent term equivalent 12 2 BayleyIII III (Bayley-III 8 mildmoderate mild moderate 7 Pearsons Pearson s 005 0 05 0.05 0.18 018 -0.1 catchup catch up an 081 81 0.8 score. . score) 15 00 0.0 0.1 01 -0. 08 0. -0 -

Respiratory syncytial virus (RSV) is the commonest cause of lower respiratory tract infection (LRTI) in children, particularly those aged <1 year. In South Africa (SA), increased hospitalisation rates during the RSV season, including access to intensive care facilities, place a huge burden on the healthcare system. Furthermore, RSV-LRTI during early childhood may lead to long-term respiratory sequelae, including recurrent wheezing, asthma, and impairment of lung function. Recently, two new RSV prevention strategies have emerged: nirsevimab, a long-acting monoclonal antibody, and a maternal RSV vaccine. Both strategies have shown high efficacy in reducing RSV-LRTI hospitalisation in infants and are being considered for licensure in SA. Implementation of these prevention strategies, combined with public engagement and collaboration between stakeholders, could significantly reduce RSV-related morbidity and mortality in SA.

ABSTRACT Respiratory syncytial virus (RSV) infections constitute a significant cause of morbidity, hospitalization, school and work absenteeism, as well as mortality worldwide, including in Paraguay. Currently, tools for RSV prevention are available. In 2012, Paraguay approved the use of palivizumab (MedImmune, USA), a monoclonal antibody produced through recombinant DNA technology. This antibody is administered in 5 doses, every 30 days and is indicated in infants born prematurely and those with cardiopulmonary disorders. Furthermore, a novel tool for RSV prevention has recently become available. Nirsevimab, a long-acting monoclonal antibody specific to the prefusion conformation of the F protein, has been approved by both the European Medicines Agency (EMA) and the Food and Drug Administration (FDA). This monoclonal antibody is indicated for the prevention of acute lower respiratory tract infections caused by RSV in newborns and infants born during or entering their first RSV season, as well as in premature infants and infants up to 24 months of age who remain vulnerable to severe RSV disease during their second RSV season. After analyzing the epidemiological situation of RSV in our country and evaluating the evidence of efficacy, efficiency, and effectiveness of this monoclonal antibody, academic institutions, scientific societies, and non-governmental and governmental organizations developed consensus guidelines on a new prevention alternative for the prevention of RSV infections, suggesting the incorporation of Nirsevimab in children under 12 months of age before their first RSV season and replacing Palivizumab. The new monoclonal has the potential to change the panorama of RSV infections in infants and produce an impact on the reduction of infant mortality and morbidity reducing the burden on the health system by decreasing hospital bed occupancy both in wards and in intensive care units, as well as the decrease in the burden on caregivers, physicians and health care providers.

RESUMEN Las infecciones por el VSR en constituyen una causa importante de morbilidad, hospitalización, ausentismo escolar y laboral, así como de mortalidad, en el mundo, así como en el Paraguay.En la actualidad, existen herramientas para la prevención del VSR. En el año 2012, el Paraguay, ha incorporado el palivizumab (MedImmune, EE. UU.), anticuerpo monoclonal, producido por tecnología de DNA recombinante. Este anticuerpo se administra en 5 dosis, cada 30 días y está indicado en lactantes nacidos prematuros y aquellos con trastornos cardiopulmonares. Por otro lado, actualmente se cuenta con una nueva herramienta para la prevención del VSR. El anticuerpo monoclonal de vida media prolongada Nirsevimab, específico para la conformación de prefusión de la proteína F, aprobado por EMA y FDA. Este monoclonal, está indicado para la prevención de las Infecciones respiratorias agudas bajas, causada por VSR en recién nacidos y lactantes nacidos durante o al ingresar a su primera temporada de VSR, en prematuros y lactantes hasta los 24 meses de edad que siguen siendo vulnerables a la enfermedad grave por VSR durante su segunda temporada de VSR. Luego de analizar la situación epidemiológica del VSR en el país así como la evidencia de eficacia, eficiencia y efectividad de este monoclonal; instituciones académicas, sociedades científicas, organizaciones no gubernamentales y gubernamentales se reunieron y elaboraron un consenso interinstitucional para la prevención de las infecciones por VSR, sugiriendo la incorporación del Nirsevimab, en menores de 12 meses de edad antes de su primera temporada de VSR y en reemplazo del Palivizumab, debido a que el nuevo monoclonal tiene el potencial de cambiar el panorama de las infecciones por VSR en el lactante y producir un impacto en la reducción la mortalidad y morbilidad infantil; reduciendo la carga al sistema de salud, en lo que se refiere a la disminución de la ocupación de camas hospitalarias tanto en sala como en unidades de cuidados intensivos, así como la disminución de la carga para los cuidadores, médicos y proveedores de atención médica y la mortalidad infantil.

RESUMEN La hiperostosis cortical infantil (HIC) o enfermedad de Caffey es un trastorno óseo autolimitado que se caracteriza por fiebre, irritabilidad, inflamación de los tejidos blandos y engrosamiento cortical de uno o más huesos. Es más común en el primer semestre de vida. Se informa el caso de un lactante de 3 meses con las características clínico-radiográficas propias de la enfermedad y los hallazgos de laboratorio más comunes que permitieron un acertado diagnóstico y seguir una conducta adecuada. El cuadro agudo se mantuvo durante pocos días y se observó resolución total del edema en cuatro semanas. El reconocimiento de esta rara infección evitará adoptar métodos diagnósticos y terapéuticos invasivos para el paciente.

ABSTRACT Infantile cortical hyperostosis (ICH) or Caffey disease is a self-limiting bone disorder characterized by fever, irritability, soft tissue swelling and cortical bone thickening. It is more common in infants < 6 months of age. We report the case of a 3-month-old infant with the clinical and radiographic characteristics of the disease and the most common laboratory findings which enabled an accurate diagnosis and appropriate management. The acute episode persisted for several days, followed by a complete resolution of the edema within four weeks. Identifying this rare infection will help avoid invasive diagnostic and therapeutic strategies.

The articles were compiled, and their characteristics, objectives and methods were studied using the following keywords: "probiotics", "S. mutans", "oral health", "biofilm", among others. For the present literature review, 10 studies were chosen that investigate the probiotic action of certain strains such as Lactobaccillus and Bifidobacterium in periodontal and orthodontic treatments, among others. These studies proved their efficacy in different types of presentations such as tablets and yogurt, in different types of populations such as infants, young people and older adults. Finally, a large part of these studies determined biofilm reduction. Based on the research articles, strains such as Lactobaccillus and Bifidobacterium showed positive effects in the reduction of bacterial plaque such as S. mutans in short- and long-term periods in different populations. There is a large production of studies concerning the application of probiotics in dentistry. However, it is necessary to carry out studies with other types of bacteria and different vehicles to determine more precisely which species help to maintain oral health.

Abstract The eHealth technologies promote parental care practices for preterm infants. Nonetheless, we should underscore the abundant information and available apps and disparities in these resources’ quality, usability, and reliability. This article examines eHealth technologies directed at parents to care for preterm infants. An integrative review was conducted across the principal health databases (Capes, EBSCO, BVS, PubMed, Scholar, and SciELO), selecting works published from 2011 to 2022 in Portuguese and English, focusing on the use of eHealth technologies for the care of preterm infants. We identified 13 articles related to information and communication technologies in strategies for educating and promoting the health of preterm infants and their parents and the importance of evaluating and validating eHealth technologies in maternal and child health promotion. Properly validated eHealth technologies can be crucial in supporting parents in promoting health and providing care for preterm infants after hospital discharge, which, in turn, can drive the evolution of healthcare systems and improve clinical practices.

Abstract Objective: Signs and symptoms of osteomyelitis or septic arthritis in neonates and infants are often nonspecific and early-stage bone infections in infants may often go unnoticed. The objective of this study was to analyze the clinical characteristics of newborns and infants with osteomyelitis and septic arthritis to improve understanding of the disorder and to assist clinicians with diagnosis. Methods: A retrospective multicenter study was conducted on neonates (0-28 days old, n = 94) and infants (1–12 months old, n = 415) with osteoarticular infections. Data consisting of clinical characteristics, complications, laboratory outcomes, and the pathogenic microorganisms causing osteomyelitis were tabulated. The statistics were further broken down into two regions and the significant differences between neonates and infants were evaluated and compared to the literature. Results: Compared to infants, neonates had significantly lower incidences of fever (p < 0.0001), higher incidences of localized swelling (p = 0.0021), higher rate of infection at the humerus (p = 0.0016), higher percentage of Escherichia coli (p < 0.0001) and Klebsiella pneumoniae (p = 0.0039) infections, lower percentage of Staphylococcus aureus infections (p < 0.0001) and were more likely to develop septic arthritis (p < 0.0001). Conclusion: Distinct differences were found between neonatal and infants with osteoarticular infections. Future studies should focus on improving diagnosis and subsequent treatment regimens for younger age groups.

Abstract Objective: To evaluate exclusive breastfeeding at discharge and hospital length-of-stay in pre-term infants undergoing or not the Kangaroo-Mother Care Method (KMC). Methods: A retrospective cohort study was conducted including preterm infants < 1800 g admitted to the neonatal unit of a KMC reference center. The infants were grouped into the KMC group and the non-KMC group. Multiple logistic and Poisson regressions were performed to evaluate the association between the KMC and two outcomes, exclusive breastfeeding at discharge, and hospital length-of-stay, adjusted for potential confounders. Results: 115 mother-infant dyads were included, 78 in the KMC group and 37 in the non-KMC group. In the bivariate analysis, the KMC group had a lower prevalence of maternal adverse conditions (6% vs. 32%, p < 0.001), a higher number of prenatal visits (median 6 vs. 3.5, p < 0.001), higher gestational ages (median 32 vs. 31 weeks, p < 0.05), higher birth weights (median 1530 vs. 1365 g, p < 0.01), a lower prevalence of necrotizing enterocolitis (3.8% vs. 16.2%, p < 0.05), parenteral nutrition (50% vs. 73%, p < 0.05), and deep vascular access (49.7% vs. 78.4%, p < 0.01), a higher prevalence of exclusive breastfeeding (65% vs. 8%, p < 0.001) and a shorter length of hospital stay (median 28 vs. 42 days, p < 0.001). In the multiple regression analysis, the KMC group was 23 times more likely to be exclusively breastfed at discharge (OR = 23.1; 95% CI = 4,85–109,93) and had a 19% reduction in the hospital length-of-stay (IDR = 0.81; 95% CI = 0.76–0.86) compared to the non-KMC group. Conclusions: The KMC is associated with better short-term neonatal outcomes and should be encouraged in all Brazilian maternity hospitals.
