How can we improve the quality of health care in hospital attendance of medically complex children? / ¿Cómo podemos mejorar la calidad de la atención hospitalaria de los pacientes crónicos complejos en pediatría?

Hospital care of medically complex children (MCC) is increasing, although its real prevalence in Spain is unknown. OBJECTIVE: to analyze hospital admissions and outpatient follow-up of MCC in order to identify strategies to improve the quality of care of MCC. PATIENTS AND METHOD: An analytical, observational, and retrospective study was carried out. We included MCC who were admitted to Pediatric Hospitalization in the last 5 years, in a tertiary hospital without a specific unit for MCC. Clinical data related to their underlying pathology, outpatient visits, and hospital admissions were collected. A multivariate study was carried out to describe risk factors of the need for technological support and to predict prolonged admissions and the hospital consultation rate. RESULTS: 99 MCC (55.6% males) aged 3.9 (2-8) years were included. 41.4% of MCC required technological support at home and presented the highest number of comorbidities, hospital admissions, and care by different specialists (p < 0.01). Older MCC (p < 0.01) with underlying digestive disease (p < 0.04) and respiratory comorbidity (p < 0.04) presented a longer mean hospital stays. Younger patients with more admissions, longer average stay, and a lack of follow-up by the link nurse were associated with a greater number of annual consultations (p < 0.05). CONCLUSIONS: MCC require a high number of annual consultations and have long hospital stays. The creation of specialized consultations for MCC, multidisciplinary care, and the participation of the link nurse are strategies to improve the quality of care for MCC in hospitals without specific MCC units.

Clinical Relevance of RSV and SARS-CoV-2 Coinfections in Infants and Young Children.

We analyzed the frequency, clinical impact and severity of respiratory syncytial virus (RSV) and SARS-CoV-2 coinfections in a single pediatric center between March 2020 and January 2023. Compared to single RSV infections, RSV/SARS-CoV-2 coinfections were uncommon (2.1%), occurred more frequently during circulation of omicron, and were associated with increased disease severity as defined by longer hospitalization and increased need for high-flow nasal cannula.

Clinical Phenotype of Respiratory Syncytial Virus Bronchiolitis before and during the Coronavirus Disease 2019 Pandemic.

OBJECTIVE: The main objective of this report was to comprehensively analyze the clinical characteristics of children hospitalized with respiratory syncytial virus (RSV) infections in 2021 during the coronavirus disease 2019 (COVID-19) pandemic and to compare them with those in the five previous RSV seasons. We hypothesized that the clinical and demographic features of children hospitalized with RSV infection in 2021 were different from those hospitalized in previous respiratory seasons. STUDY DESIGN: In this retrospective observational study, children younger than 2 years hospitalized with RSV bronchiolitis from January 1, 2015, to December 31, 2021, at the Department of Pediatrics of the Hospital Gregorio Marañón, Madrid, Spain, were included. We compared the clinical characteristics of children hospitalized with RSV bronchiolitis in the five seasons before the COVID-19 pandemic and during the subsequent off-seasonal surge of RSV infections. RESULTS: We found a significant reduction in hospitalizations for RSV bronchiolitis during the usual winter epidemic period due to the COVID-19 pandemic. Children hospitalized with RSV infection in 2021, during the COVID-19 pandemic, were older than children hospitalized in the prepandemic period (2015-2020; 4.0 [1.6-9.2] vs. 3 [1.5-6.5] months; p < 0.01). We also found shorter duration of oxygen days during the COVID-19 period compared with previous respiratory seasons (3 [2-5] vs. 4 [2-6] days; p = 0.02). CONCLUSION: The COVID-19 pandemic modified the RSV seasonality with a significant reduction in RSV hospitalizations during the expected 2020-2021 season and a reappearance of RSV 7 months later than expected. We also found changes in the median age of children with RSV bronchiolitis during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic compared with the prepandemic RSV seasons and shorter duration of oxygen days suggesting a modest reduction in disease severity. We hypothesize that this observation reflects the lack of RSV circulation in the previous months (April 2020-March 2021), with a larger pool of vulnerable infants that had not been previously infected. KEY POINTS: · The COVID-19 pandemic shifted RSV seasonality.. · RSV children hospitalized during the pandemic were older.. · Modest reduction in disease severity was observed during the pandemic..

¿Sobreestimamos las necesidades de líquidos? Complicaciones del uso de sueros isotónicos de mantenimiento en plantas de hospitalización pediátrica / Do we overestimate intravenous fluid therapy needs? Adverse effects related to isotonic solutions during paediatric hospital admissions

Introducción: La fluidoterapia intravenosa es un tratamiento ampliamente utilizado en pacientes pediátricos hospitalizados. El objetivo del estudio fue analizar las complicaciones asociadas al uso de sueros isotónicos de mantenimiento en pacientes hospitalizados y comparar la frecuencia de aparición de estas complicaciones con distintos ritmos de administración. Materiales y métodos: Se realizó un estudio observacional y prospectivo, en el que se incluyeron pacientes hospitalizados de entre tres meses y 15 años de edad que recibieron tratamiento con fluidoterapia isotónica 0,9% con glucosa al 5% durante las primeras 24 horas de ingreso. Se dividieron en dos cohortes según el ritmo de fluidoterapia: restringido<100% vs. no restringido cercano al 100% necesidades basales (NNBB), calculadas según la regla de Holliday y Segar. Se recogieron variables clínicas y analíticas en dos tiempos de estudio (T0 al ingreso y T1 a las 24 horas de la fluidoterapia). Se realizó un estudio uni y multivariante para identificar factores de riesgo de complicaciones. Resultados: Se incluyeron 84 pacientes, de los cuales 33 recibieron fluidoterapia restringida y 51 pacientes con 100% NNBB. Las principales complicaciones desarrolladas en las primeras 24 horas fueron hipercloremia> 110 mEq/L (16,6%) y edemas (19%). La aparición de edemas fue más frecuente en pacientes de menor edad (p <0,01) y la hipercloremia se asoció con el desarrollo de edemas (OR 1,73 [1,0-3,8]), p=0,06. Conclusiones: La administración de sueros isotónicos no está exenta de complicaciones, probablemente relacionadas con el ritmo de administración y más frecuentes en lactantes. Son necesarios estudios que revisen las necesidades de líquidos en niños hospitalizados. (AU)

Introduction: Maintenance intravenous fluids are frequently used in hospitalised paediatric patients. The aim of the study was to describe the adverse effects of isotonic fluid therapy in hospitalised patients, and its prevalence based on the rate of infusion. Materials and methods: A prospective clinical observational study was designed. We included hospitalised patients between 3 months-old and 15-years-old were included with 0.9% isotonic solutions with 5% glucose within the first 24h of administration. They were divided into two groups, depending on the quantity of liquid they received (restricted<100% vs. 100% maintenance needs). Clinical data and laboratory findings were recorded in two different times (T0 when they were admitted to hospital and T1 within the first 24h of administration). Results: The study included 84 patients, 33 received <100% maintenance needs and 51 patients received around 100%. The main adverse effects notified in the first 24h of administration were hyperchloremia>110mEq/L (16.6%) and oedema (19%). Oedema was more frequent in patients with lower age (p<0.01). The hyperchloremia at 24h of intravenous fluids was an independent risk factor of developing oedema (OR 1.73 [1.0–3.8], p=0.06). Conclusions: The use of isotonic fluids is not free from adverse effects, probably related to the rate of infusion and more likely to appear in infants. It is necessary more studies that review the correct estimation of intravenous fluid needs in hospitalised children. (AU)

Age and respiratory syncytial virus etiology in bronchiolitis clinical outcomes.

Background: Respiratory syncytial virus (RSV) is the most frequent cause of bronchiolitis. Precise and updated information about demographic characteristics, clinical manifestations, and risk factors for severe disease are needed for optimal implementation of upcoming new therapeutic and preventive interventions. Objectives: The main goals of this study were to define the epidemiology of acute bronchiolitis in hospitalized young children during 5 calendar years in Spain; evaluate the differences in clinical manifestations between children hospitalized with RSV infection and those hospitalized with non-RSV infection; and identify demographic characteristics, clinical parameters, and risk factors associated with disease severity. Methods: We performed a retrospective review of the medical records of children younger than 2 years who were hospitalized with bronchiolitis between January 2015 and December 2019. We constructed multivariable models to identify independent predictors of disease severity defined as length of hospital stay (LOS), pediatric intensive care unit (PICU) admission, and need for a high-flow-nasal canula (HFNC). Results: From January 2015 to December 2019, 1437 children were hospitalized with bronchiolitis and met the inclusion criteria. The proportion of children hospitalized with bronchiolitis caused by RSV increased significantly during the study period, from 60% to 65% (P = .03). The children with RSV bronchiolitis were younger than those with non-RSV bronchiolitis (median age = 3 months [interquartile range = 1.5-6.5 months] vs 4 months [interquartile range = 2-7.5 months], respectively (P < .01). The children younger than 6 months with RSV bronchiolitis had enhanced disease severity compared with those with non-RSV bronchiolitis, as defined by an LOS of more than 4 days, severity scores, need for an HFNC, intravenous fluids, enteral feeding, and PICU admissions (P < .01). Age younger than 6 months and RSV-positive etiology were independently associated with greater odds of PICU admission, need for an HFNC, and longer LOS. Conclusion: This study identified differences in disease severity between young children with RSV bronchiolitis and those with non-RSV bronchiolitis. These differences are particularly significant in children younger than 6 months, who comprise a group of infants with suboptimal innate immunity to RSV and may benefit from new preventive strategies.

Role of G2-S16 Polyanionic Carbosilane Dendrimer in the Prevention of Respiratory Syncytial Virus Infection In Vitro and In Vivo in Mice.

The respiratory syncytial virus (RSV) causes respiratory infection and bronchiolitis, requiring hospitalization mainly in infants. The interaction between RSV, envelope glycoproteins G and F, and cell surface heparan sulfate proteoglycans (HSPG) is required for binding and entry into the host cells. A G2-S16 polyanionic carbosilane dendrimer was identified as a possible RSV inhibitor. We speculated that the G2-S16 dendrimer adheres to the host cell-surface HSPG, acts through binding to HS receptors, and prevents further RSV infection. The G2-S16 dendrimer was non-toxic when applied intranasally to Balb/c mice, and interestingly enough, this G2-S16 dendrimer inhibits 85% RSV. Therefore, our G2-S16 dendrimer could be a candidate for developing a new possible therapy against RSV infection.

Impact of an Asthma Education Program During Admission.

OBJECTIVES: Health educational interventions improve health outcomes and quality of life in children with asthma. The main purpose of this study was to evaluate the effect of an education intervention for an asthma inhaler technique during hospital admission for an asthma exacerbation. METHODS: This prospective study was conducted in a pediatric hospitalization unit of a third-level hospital. Children admitted for an asthma exacerbation were eligible for inclusion. It was developed in 2 phases: during hospital admission (T1) and 1 month after discharge (T2). In the T1 phase, caregivers completed the questionnaire to assess asthma control in children (CAN questionnaire) and performed the inhaler technique, which was evaluated with a 6-step checklist. An educational intervention was performed. In the T2 phase, caregivers completed the CAN questionnaire, and the inhaler technique was reevaluated. We hypothesized that the inhaler technique improved after the implementation of an asthma education program. RESULTS: A total of 101 children were included, of whom 85 completed the T2 phase (84%). At baseline, 11.8% of participants performed the inhaler technique correctly. All steps of the inhaler technique upgraded in the T2 phase significantly (P < .01), except for the step "assemble the inhaler device correctly." Former evaluation by a pediatric pneumologist was associated with a higher score in the inhaler technique in the T1 phase. The median CAN questionnaire score in the T1 phase was 8 (interquartile range 4-16), which reduced to 4 (interquartile range 1.2-6) in the T2 phase (P < .01). CONCLUSIONS: The development of an educational intervention during admission improved inhaler technique as well as asthma knowledge.

Nasal and Fecal Microbiota and Immunoprofiling of Infants With and Without RSV Bronchiolitis.

Bronchiolitis associated with the respiratory syncytial virus (RSV) is the leading cause of hospitalization among infants aged < 1 year. The main objective of this work was to assess the nasal and fecal microbiota and immune profiles in infants with RSV bronchiolitis, and to compare them with those of healthy infants. For this purpose, a total of 58 infants with RSV-positive bronchiolitis and 17 healthy infants (aged < 18 months) were recruited in this case-control study, which was approved by the Ethics Committee of the Hospital Gregorio Marañón. Nasal and fecal samples were obtained and submitted to bacterial microbiota analysis by 16S rDNA sequencing and to analysis of several immune factors related to inflammatory processes. Nasal samples in which Haemophilus and/or Moraxella accounted for > 20% of the total sequences were exclusively detected among infants of the bronchiolitis group. In this group, the relative abundances of Staphylococcus and Corynebacterium were significantly lower than in nasal samples from the control group while the opposite was observed for those of Haemophilus and Mannheimia. Fecal bacterial microbiota of infants with bronchiolitis was similar to that of healthy infants. Significant differences were obtained between bronchiolitis and control groups for both the frequency of detection and concentration of BAFF/TNFSF13B and sTNF.R1 in nasal samples. The concentration of BAFF/TNFSF13B was also significantly higher in fecal samples from the bronchiolitis group. In conclusion, signatures of RSV-associated bronchiolitis have been found in this study, including dominance of Haemophilus and a high concentration of BAFF/TNFSF13B, IL-8 and sTNF.R1 in nasal samples, and a high fecal concentration of BAFF/TNFSF13B.

Monoclonal Antibodies for Prevention of Respiratory Syncytial Virus Infection.

Respiratory syncytial virus (RSV) is the leading cause of hospitalizations in infants worldwide. Palivizumab, a humanized monoclonal antibody against the RSV F protein, is the only licensed agent for prevention of severe RSV infection in high-risk infants. Palivizumab is administered intramuscularly, every month during the RSV season, usually 5 doses are required. In recent years, the resolution of the structure of the RSV F protein, with identification of potent neutralizing epitopes, and new technologies for production of monoclonal antibodies (mAbs) have facilitated the development of new alternative strategies for the prevention of RSV infections. One promising approach is a new generation of mAbs directed to new neutralizing epitopes and with prolonged half life. These enhanced mAbs are expected to provide adequate protection during the complete RSV season with a single intramuscular (IM) dose. The long-term goal of this approach is to provide passive immunization for the prevention of RSV lower respiratory tract infection to all infants (preterm and full term) in the first months of life before their initial exposure to RSV.

Experiencias en Cuba sobre la utilización de métodos colaborativos de aprendizaje en asignaturas de la carrera Ciencias de la Información / Cuban experiences in the use of collaborative learning methods in Information Sciences undergraduate courses

Los métodos colaborativos permiten desarrollar habilidades y actitudes en los estudiantes para descubrir y construir conocimientos por ellos mismos, a la vez que promueven la interdependencia a la hora de resolver problemas profesionales. Esta investigación tuvo como objetivo mostrar las experiencias y los resultados del trabajo con métodos colaborativos en tres asignaturas de la carrera Ciencias de la Información de dos universidades cubanas. Se realizó un estudio descriptivo en el que se utilizaron métodos empíricos, como un análisis documental clásico, entrevistas semiestructuradas a los jefes de equipos y encuestas estructuradas a 70 estudiantes (100 por ciento) que constituyeron la población. Se constató que, de forma general, la aplicación de técnicas didácticas activas mostró resultados positivos tanto en la evaluación de los resultados docentes como en la asistencia a clases. De igual manera, se logró que los alumnos diseñaran su estructura de interacciones y asumieran diferentes roles para intervenir en las comunidades desde una perspectiva informacional. Las opiniones de los estudiantes se tuvieron en cuenta para realizar mejoras en el diseño de las asignaturas. Por las condiciones impuestas por la pandemia COVID 19, las clases se adaptaron a condiciones no presenciales, lo que conllevó un incremento en el uso de las redes sociales digitales para la comunicación entre los alumnos y los profesores(AU)

Collaborative methods provide students with the skills and attitudes required to discover and build knowledge by themselves, and foster interdependence when solving professional problems. The purpose of the study was to present the experiences and results obtained from the use of collaborative methods in three Information Sciences undergraduate courses taught in two Cuban universities. A descriptive study was conducted based on empirical methods such as classic document analysis, semi-structured interviews with team leaders, and structured surveys to 70 students (100 percengt), who made up the study population. It was found that the use of active didactic techniques generally led to positive academic results and better attendance to class. Students could also design their own structure of interactions, taking on different roles to intervene in communities from an information perspective. Students' opinions were taken into account for curriculum development. Due to the limitations imposed by the COVID-19 pandemic, classes were not attended physically, expanding the use of digital social networking for communication between students and teachers(AU)

Longitudinal plasma cytokine concentrations and recurrent wheezing after RSV bronchiolitis.

BACKGROUND: Respiratory syncytial virus (RSV) bronchiolitis in young children has been associated with increased risk for developing recurrent wheezing, but the underlying mechanisms, are not completely defined. We hypothesized that RSV induces a disregulated immune response defined by a distinct cytokine profile in infants at increased risk for developing recurrent wheezing. METHODS: Previously healthy infants less than 12 months of age hospitalized with a first episode of RSV bronchiolitis were enrolled and blood samples and clinical and epidemiological data collected. A group of healthy non-infected controls were enrolled in parallel. Children were followed longitudinally and subsequent blood samples collected in RSV-infected infants at one month and at one year after hospital discharge to measure longitudinal plasma concentrations of IFN-γ, TNF-α, IL-2, IL-4, IL-6, IL-8, IL-10, IL-12, IL-17 and IL1-ß. Risk of post-RSV wheezing was assessed by Poisson modelling. RESULTS: From October 2008 to March 2012 we enrolled 37 infants hospitalized with RSV bronchiolitis and 9 healthy age-matched controls. Within the RSV cohort, 17 (46%) children developed recurrent wheezing within the following 12 months. Plasma cytokine profiles measured during the acute infection were similar in children who developed recurrent wheezing versus those who did not, but lower in healthy controls vs RSV infants who subsequently developed wheezing. At one month and 12 months post-acute RSV infection, infants who developed recurrent wheezing had higher IFN-γ plasma concentrations versus those with no-wheezing (p < 0.05). Moreover, IFN-γ concentrations were identified as independent predictor of post-RSV wheezing. CONCLUSIONS: Children with RSV-associated recurrent wheezing had persistently elevated plasma concentrations of IFN-γ for a year after acute infection, suggesting that this cytokine could be used as a biomarker for risk of recurrent wheezing and possibly plays a role in the pathogenesis of this condition.

The clinical relevance of the microbiome when managing paediatric infectious diseases-Narrative review.

In recent years, the field of infectious diseases has been hit by the overwhelming amount of information generated while the human microbiome is being disentangled. Based on the interaction between the microbiota and the immune system, the implications regarding infectious diseases are probably major and remain a challenge. AIMS: This review was conceived as a comprehensive tool to provide an overview of the available evidence regarding the influence of the microbiome on infectious diseases in children. METHODS: We present the main findings aroused from microbiome research in prevention, diagnosis and treatment of infectious disease under a paediatric perspective, to inform clinicians of the potential relevance of microbiome-related knowledge for translation to clinical practice. RESULTS AND CONCLUSION: The evidence shown in this review highlights the numerous research gaps ahead and supports the need to move forward to integrating the so-called microbiome thinking into our routine clinical practice.

Neurologic Complications in Children Hospitalized With Influenza Infections: Prevalence, Risk Factors and Impact on Disease Severity.

BACKGROUND: Influenza infection is a common cause of respiratory disease and hospitalization in children. Neurologic manifestations of the infection have been increasingly reported and may have an impact on the severity of the disease. The aim of this study is to describe neurologic events in pediatric patients hospitalized with influenza and identify associated risk factors. METHODS: Retrospective cohort study which included all hospitalized patients with microbiologic confirmation of influenza disease over 4 epidemic seasons, focusing on neurologic complications. Demographic, laboratory and clinical data, as well as past history, were recorded. Descriptive and analytic statistical study was performed using SPSS and R statistical software. RESULTS: Two hundred forty-five patients were included. Median age was 21 months (interquartile range, 6-57) and 47.8% had a previous underlying condition. Oseltamivir was administered to 86% of patients, median hospitalization was 4 days (interquartile range, 3-6), and pediatric intensive care unit admission rate 8.9%. Twenty-nine patients (11.8%) developed neurologic events, febrile seizures being the most frequent, followed by nonfebrile seizures and encephalopathy. Status epilepticus occurred in 4 children, and 69.6% of seizures recurred. Patients with a previous underlying condition were at greater risk of developing a neurologic complication [odds ratio (OR), 4.55; confidence interval (CI), 95% 1.23-16.81). Male sex (OR, 3.21; CI 95%, 1.22-8.33), influenza B virus (OR, 2.82; CI 95%, 1.14-7.14) and neurologic events (OR, 3.34; CI 95%, 1.10-10.19) were found to be risk factors for pediatric intensive care unit admission. CONCLUSIONS: A significant proportion of influenza-related hospitalized patients develop neurologic complications, especially seizures which may be prolonged or recurrent. Previous underlying conditions pose the greatest risk to neurologic events, which increase disease severity.

The journey to a respiratory syncytial virus vaccine.

OBJECTIVE: The high burden associated with respiratory syncytial virus (RSV) has made the development of RSV vaccine(s) a global health high priority. This review summarizes the journey to an RSV vaccine, the different strategies and challenges associated with the development of preventive strategies for RSV, and the diverse products that are undergoing clinical testing. DATA SOURCES: Studies on RSV biology, immunology, epidemiology, and monoclonal antibodies (mAbs) and vaccines were searched using MEDLINE. We also searched PATH.org and ClinicalTrials.gov for updated information regarding the status of RSV vaccines and mAbs undergoing clinical trials. STUDY SELECTIONS: We selected relevant studies conducted in infants and young children, pregnant women, and elderly population for the prevention of RSV infection. RESULTS: Identification of a safe and immunogenic vaccine has been an important but elusive initiative for more than 60 years for different reasons, including the legacy of formalin-inactivated vaccine, our limited understanding of the immune response to RSV and how it relates to clinical disease severity, or the need for different end points according to the different vaccine platforms. Nevertheless, there are currently 39 vaccines and mAbs under development and 19 undergoing clinical trials. CONCLUSION: Over the past decade, there have been significant advances in our knowledge of RSV molecular and structural biology and in understanding the human immune response to RSV. Despite the barriers, there are several promising mAbs and RSV vaccines undergoing clinical trials that hope to offer protection to the most vulnerable populations.
