High-Flow Oxygen and Other Noninvasive Respiratory Support Therapies in Bronchiolitis: Systematic Review and Network Meta-Analyses.

OBJECTIVES: We present a systematic review on the effectiveness of noninvasive respiratory support techniques in bronchiolitis. DATA SOURCES: Systematic review with pairwise meta-analyses of all studies and network meta-analyses of the clinical trials. STUDY SELECTION: Patients below 24 months old with bronchiolitis who require noninvasive respiratory support were included in randomized controlled trials (RCTs), non-RCT, and cohort studies in which high-flow nasal cannula (HFNC) was compared with conventional low-flow oxygen therapy (LFOT) and/or noninvasive ventilation (NIV). DATA EXTRACTION: Emergency wards and hospitalized patients with bronchiolitis. DATA SYNTHESIS: A total of 3,367 patients were analyzed in 14 RCTs and 8,385 patients in 14 non-RCTs studies. Only in nonexperimental studies, HFNC is associated with a lower risk of invasive mechanical ventilation (MV) than NIV (odds ratio, 0.49; 95% CI, 0.42-0.58), with no differences in experimental studies. There were no differences between HFNC and NIV in other outcomes. HFNC is more effective than LFOT in reducing oxygen days and treatment failure. In the network meta-analyses of clinical trials, NIV was the most effective intervention to avoid invasive MV (surface under the cumulative ranking curve [SUCRA], 57.03%) and to reduce days under oxygen therapy (SUCRA, 79.42%), although crossover effect estimates between interventions showed no significant differences. The included studies show methodological heterogeneity, but it is only statistically significant for the reduction of days of oxygen therapy and length of hospital stay. CONCLUSIONS: Experimental evidence does not suggest that high-flow oxygen therapy has advantages over LFOT as initial treatment nor over NIV as a rescue treatment.

Spanish National Registry of Paediatric Coeliac Disease: Changes in the Clinical Presentation in the 21st Century.

OBJECTIVES: Over the last several decades, there has been a tendency towards a predominance of less symptomatic forms of coeliac disease (CD) and an increase in the patient age at diagnosis. This study aimed to assess the clinical presentation and diagnostic process of paediatric CD in Spain. METHODS: A nationwide prospective, observational, multicentre registry of new paediatric CD cases was conducted from January 2011 to June 2017. The data regarding demographic variables, type of birth, breast-feeding history, family history of CD, symptoms, height and weight, associated conditions, serological markers, human leukocyte antigen (HLA) phenotype, and histopathological findings were collected. RESULTS: In total, 4838 cases (61% girls) from 73 centres were registered. The median age at diagnosis was 4 years. Gastrointestinal symptoms were detected in 71.4% of the patients, and diarrhoea was the most frequent symptom (45.9%). The most common clinical presentation was the classical form (65.1%) whereas 9.8% ofthe patients were asymptomatic. There was a trend towards an increase in the age at diagnosis, proportion of asymptomatic CD cases, and usage of anti-deamidated gliadin peptide antibodies and HLA typing for CD diagnosis. There was, however, a decreasing trend in the proportion of patients undergoing biopsies. Some of these significant trend changes may reflect the effects of the 2012 ESPGHAN diagnosis guidelines. CONCLUSIONS: Paediatric CD in Spain is evolving in the same direction as in the rest of Europe, although classical CD remains the most common presentation form, and the age at diagnosis remains relatively low.

Correlation of Anti-Tissue Transglutaminase Antibodies With the Mucosal Changes and IgA Status of Children With Celiac Disease.

OBJECTIVES: The objective of this study was to assess the association between serological markers and changes of the intestinal mucosa in children with celiac disease (CD). METHODS: Clinical data from CD patients under 15 years old were collected from the participating centers in an on-line multicenter nationwide observational Spanish registry called REPAC-2 (2011-2017). Correlation between anti-tissue transglutaminase antibodies (t-TGA) levels and other variables, including mucosal damage and clinical findings (symptoms, age, and gender), was assessed. RESULTS: A total of 2955 of 4838 patients had t-TGA and a small bowel biopsy (SBB) performed for CD diagnosis. A total of 1931 (66.2%) patients with normal IgA values had a Marsh 3b-c lesion and 1892 (64.9%) had t-TGA Immunoglobulin A (IgA) ≥ 10 times upper limit of normal (ULN). There is a statistically significant association between t-TGA IgA levels and the degree of mucosal damage ( P < 0.001), the higher the t-TGA IgA levels the more severe the mucosal damage. Those patients who reported symptoms had more severe mucosal damage ( P = 0.001). On the contrary, there was a negative association between age and changes of the intestinal mucosa ( P < 0.001). No association was found with gender. Regarding the IgA-deficient patients, 47.4% (18 cases) had t-TGA Immunoglobulin A (IgA) ≥ 10 times ULN and a Marsh 3b-c lesion was observed in 68.4% (26 patients). No statistical relation was found between t-TGA IgG levels and the changes of the intestinal mucosa, neither a relation with age, gender, or symptoms. CONCLUSIONS: There is a positive correlation between t-TGA IgA levels and the severity of changes of the intestinal mucosa. Such correlation was not found in IgA-deficient patients who had positive t-TGA IgG serology. The results in this group of patients support the European Society for Paediatric Gastroenterology, Hepatology, and Nutrition recommendations about the need of performing a SBB in IgA-deficient individuals despite high t-TGA IgG levels.

Adherence of Spanish pediatricians to "do not do" guidelines to avoid low-value care in pediatrics.

The main objective of this study was to analyze the degree of knowledge and compliance of Spanish pediatricians with the "do not do" recommendations of the Spanish Association of Pediatrics. A nationwide cross-sectional, descriptive study was carried out using a 25-item questionnaire among Spanish pediatricians. Univariate, bivariate, and multivariate analyses were performed. A total of 1137 pediatricians participated in the study. Most of them were women (75.1%), older than 55 (28.3%), worked in specialized care (56.9%), with public financing (91.2%), and had been working for more than 20 years (44.9%). The median of inappropriate answers per question was 9.1%. The bivariate and multivariate analyses showed that the factors that influenced higher adequacy to the "do not do" recommendations were younger than 45 years, working in specialized care, and working in the public health system. CONCLUSION: This research is the first nationwide study in Spain to analyze the adequacy of "do not do" pediatric clinical recommendations. The study showed a high level of compliance by Spanish pediatricians with these recommendations. However, there is a lack of knowledge in less frequent infectious pathologies such as HIV or fungal infections, in not prolonging antibiotic treatment unnecessarily and directing it appropriately according to the antibiogram results. These aspects may be improved by designing measures to enhance pediatricians' knowledge in these specific aspects. Some demographical factors are related to higher adequacy. Performing this research in other countries may allow assessing the current clinical practice of pediatricians. WHAT IS KNOWN: • Low-value care is defined as care that delivers little or no benefit, may cause patients harm, or outcomes marginal benefits at a disproportionately increased cost. • Few nationwide studies have assessed adherence to "do not do" guidelines, especially in pediatric settings. WHAT IS NEW: • Albeit there is a high level of compliance by Spanish pediatricians with the «do not do¼ recommendations, there is a lack of knowledge in different aspects that may be improved. • Some demographical factors are related to higher adequacy. Performing this research in other countries may allow assessing the current clinical practice of pediatricians.

Lack of changes in preterm delivery and stillbirths during COVID-19 lockdown in a European region.

Preliminary data in Europe have suggested a reduction in prematurity rates during the COVID-19 pandemic, implying that contingency measures could have an impact on prematurity rates. We designed a population-based prevalence proportion study to explore the potential link between national lockdown measures and a change in preterm births and stillbirths. Adjusted multivariate analyses did not show any decrease in preterm proportions during the lockdown period with respect to the whole prelockdown period or to the prelockdown comparison periods (2015-2019): 6.5% (95%CI 5.6-7.4), 6.6% (95%CI 6.5-6.8), and 6.2% (95%CI 5.7-6.7), respectively. Proportions of preterm live births did not change during lockdown when different gestational age categories were analyzed, nor when birthweight categories were considered. No differences in stillbirth rates among the different study periods were found: 0.33% (95%CI 0.04-0.61) during the lockdown period vs. 0.34% (95%CI 0.22-0.46) during the prelockdown comparison period (2015-2019).Conclusion: We did not find any link between prematurity and lockdown, nor between stillbirths and lockdown. Collaborative efforts are desirable to gather more data and additional evidence on this global health issue. What is Known: • Prematurity is associated with increased risk of morbidity and mortality. • Contingency measures during the COVID-19 pandemic may have an impact on reducing prematurity rates. What is New: • Prematurity and stillbirth rates remained stable in Castilla-y-León, a Spanish region, during COVID-19 lockdown. • The role of behavioral patterns and sociocultural factors in the prevention of preterm birth as a result of lockdown measures remains a subject for debate.

Day-care center attendance and risk of Asthma-A systematic review.

INTRODUCTION AND OBJECTIVES: Asthma and other wheezing disorders are common chronic health problems in childhood. We aim to evaluate whether the attendance by children under three years of age to day-care centers is a protector or risk factor in the development of recurrent wheezing or asthma in the following years of their lives. METHODS: Systematic review of published cohort or cross-sectional studies, without any time limitation. We searched in PubMed, Cinhal, Cuiden and Scopus (EMBASE included). The quality of the studies was evaluated using the Newcastle-Ottawa Scale. Disagreements were solved by mutual consensus. Weighted odds ratio (ORs) were estimated using RevMan 5.3, following random effects models. RESULTS: We selected 18 studies for qualitative analysis, nine cohort studies and nine cross-sectional studies. Day-care center attendance is associated with an increased risk of early recurrent wheezing (four studies; 50,619 subjects; adjusted OR 1.87 [1.21 to 2.88]; I2 91%) and asthma before the age of six (five studies; 5412 subjects; adjusted OR 1.59 [1.26 to 2.01]; I2 0%), but not later (five studies; 5538 subjects; adjusted OR 0.86 [0.55 to 1.32]; I2 76%). CONCLUSIONS: Children attending day-care center during the first years of life have a higher risk of recurrent wheezing during the first three years and asthma before the age of six, but not later. This risk must be taken into account to inform parents in order to choose what kind of care children should have throughout infancy and to implement preventive measures to reduce its impact.

A clinical trial comparing propofol versus propofol plus midazolam in diagnostic endoscopy of patients with a low anesthetic risk.

BACKGROUND AND OBJECTIVES: propofol and midazolam are two of the most commonly used sedatives in upper gastrointestinal endoscopy (UGE). The objective of this study was to evaluate these two sedation regimens administered to patients who underwent an UGE with regard to security, efficiency, quality of exploration and patient response. PATIENTS AND METHODS: a prospective, randomized and double-blind study was performed which included 83 patients between 18 and 80 years of age of a low anesthetic risk (ASA - American Society of Anesthesiologists- I-II) who underwent a diagnostic UGE. Patients were randomized to receive sedation with either placebo plus propofol (group A) or midazolam plus propofol (group B). RESULTS: in group A, 42 patients received a placebo bolus (saline solution) and on average up to 115 mg of propofol in boluses of 20 mg. In group B, 41 patients received 3 mg of midazolam and an average of up to 83 mg of propofol in boluses of 20 mg. There were no significant differences in the adverse effects observed in either group and all adverse events were treated conservatively. The patients in group B (midazolam plus propofol) entered the desired sedated state more quickly with no variation in the overall time of the exploration. The quality of the endoscopic evaluation was similar in both groups and the patients were equally satisfied regardless of the sedatives they received. CONCLUSIONS: the use of midazolam plus propofol as a sedative does not affect the overall exploration time, a lower dose of propofol can be used and it is as safe as administering propofol as a monotherapy while providing the same level of both exploration quality and patient approval.

Incidence of encephalopathy and comorbidity in infants with perinatal asphyxia: a comparative prospective cohort study.

Background: Programs that aim to improve the detection hypoxic-ischemic encephalopathy (HIE) should establish which neonates suffering from perinatal asphyxia need to be monitored within the first 6 h of life. Method: An observational prospective cohort study of infants with gestational age ≥35 weeks, and above 1,800g, were included according to their arterial cord pH value (ApH): ≤7.00 vs. 7.01-7.10. Data was collected including obstetrical history, as well as neonatal comorbidities, including the presence of HIE, that happened within 6 h of life. A standardized neurological exam was performed at discharge. Results: There were 9,537 births; 176 infants with ApH 7.01-7.10 and 117 infants with ApH ≤7.00. All 9 cases with moderate-to-severe HIE occurred among infants with ApH ≤7.00. The incidence of global and moderate-severe HIE was 3/1,000 and 1/1,000 births, respectively. Outcome at discharge (abnormal exam or death) showed an OR 12.03 (95% CI 1.53, 94.96) in infants with ApH ≤7.00 compared to ApH 7.01-7.10 cohort. Ventilation support was 5.1 times (95% CI 2.87, 9.03) more likely to be needed by those with cord ApH ≤7.00 compared to those with ApH 7.01-7.10, as well as hypoglycemia (37% vs. 25%; p = 0.026). In 55%, hypoglycemia occurred despite oral and/or intravenous glucose administration had been already initiated. Conclusions: Cord pH 7.00 might be a safe pH cut-off point when developing protocols to monitor infants born with acidemia in order to identify infants with moderate or severe HIE early on. There is non-negligible comorbidity in the ApH ≤7.00 cohort, but also in the 7.01-7.10 cohort.

[Indicadores de salud perinatal en una región española entre los años 2015 y 2020.] / Perinatal health indicators in a region of Spain corresponding to the period 2015 to 2020.

OBJECTIVE: The availability in the literature of data related to perinatal variables in the Spanish population is very scarce. The aim of this study was to know the evolution of perinatal health indicators according to the risk groups of prematurity and birth weight, the proportion of multiple births, caesarean section and stillbirths. METHODS: We conducted a population-based cross-sectional study of births in eleven hospitals in Castilla y León (January 2015 to June 2020). There were 70,024 newborns from 68,769 deliveries. Jointpoint regression analysis was used to identify changes in trend over the years, and binomial logistic regression was used to adjust for the potential interaction of hospital type, sex, type of delivery and multiple births on the frequencies of prematurity and death. RESULTS: There was a 19.9% decrease in deliveries and a 42% decrease in multiple births, with no change in preterm (7.7%) and stillbirths (0.44%). The percentage of caesarean sections was 21.5% with a slight downward trend over time. Death (stillbirth) was associated with preterm multiple birth; especially with the male-male combination (p<0.05). Late preterm and early term newborns showed higher risk of death compared to term newborns: OR 7.7 (95%CI 5.6-10.7) and 2.4 (95%CI 1.6-3.6), respectively; as well as the low birth weight group (OR 17.6; 95%CI 13.9-22.2) and small for gestational age (OR 3.4; 95%CI 1.9-5.8), compared to those of adequate weight. CONCLUSIONS: Prior to the development of the COVID-19 pandemic there is a decline in births, including multiple births, with no change in stillbirths or prematurity. Late preterm and early term newborns are at increased risk of intrauterine death.

OBJETIVO: La disponibilidad en la literatura de datos relacionados con variables perinatales en la población española son muy escasos. El objetivo de este estudio fue conocer la evolución de los indicadores de salud perinatal atendiendo a los grupos de riesgo de prematuridad y de peso al nacimiento, la proporción de parto múltiple, de cesárea y de mortinatos. METODOS: Se realizó un estudio transversal poblacional de los partos en once hospitales de Castilla y León (enero de 2015 a junio de 2020). Hubo 70.024 recién nacidos (RN) procedentes de 68.769 partos. Se utilizó el análisis de regresión Jointpoint para identificar cambios en la tendencia a lo largo de los años, y la regresión logística binomial para ajustar la potencial interacción del tipo de hospital, el sexo, el tipo de parto y el parto múltiple en las frecuencias de prematuridad y de fallecimiento. RESULTADOS: Hubo un descenso de partos del 19,9% y de los múltiples del 42%, sin cambios en los RN prematuros (7,7%) ni en los mortinatos (0,44%). El porcentaje de cesáreas fue del 21,5% con una ligera tendencia temporal descendente. El fallecimiento (mortinato) se asoció al parto múltiple pretérmino; especialmente a la combinación varón-varón (p<0,05). Los RN pretérminos tardíos y términos precoces mostraron mayor riesgo de fallecer frente a los RN a término: OR 7,7 (IC95% 5,6-10,7) y 2,4 (IC95% 1,6-3,6), respectivamente; así como el grupo de bajo peso (OR 17,6; IC95% 13,9-22,2) y el pequeño para la edad gestacional (OR 3,4; IC95% 1,9-5,8), frente a los de peso adecuado. CONCLUSIONES: Previo al desarrollo de la pandemia por COVID-19 existe un descenso de la natalidad, incluidos los partos múltiples, sin cambios en los mortinatos ni en la prematuridad. Los RN pretérminos tardío y términos precoces tienen mayor riesgo de fallecer intraútero.

Coeliac Disease Case-Control Study: Has the Time Come to Explore beyond Patients at Risk?

The worldwide prevalence of asymptomatic coeliac disease (CD) is increasing, which is in part due to the routine screening of children with risk factors. Both symptomatic and asymptomatic patients with CD are at risk of long-term complications. The objective of this study was to compare the clinical characteristics of asymptomatic and symptomatic children at the time of CD diagnosis. A case-control study was conducted using data from a cohort of 4838 CD patients recruited from 73 centers across Spain between 2011 and 2017. A total of 468 asymptomatic patients (cases) were selected and matched by age and sex with 468 symptomatic patients (controls). Clinical data, including any reported symptoms, as well as serologic, genetic, and histopathologic data were collected. No significant differences were found between the two groups in most clinical variables, nor in the degree of intestinal lesion. However, the asymptomatic patients were taller (height z-score -0.12 (1.06) vs. -0.45 (1.19), p < 0.001) and were less likely to have anti transglutaminase IgA antibodies ≥ 10 times the upper normal limit (66.2% vs. 758.4%, p = 0.002). Among the 37.1% of asymptomatic patients who were not screened for CD due to the absence of risk factors, only 34% were truly asymptomatic, while the remaining 66% reported non-specific CD-related symptoms. Therefore, expanding CD screening to any child who undergoes a blood test could reduce the burden of care for some children, as many of those considered asymptomatic reported non-specific CD-related symptoms.

Management of acute bronchiolitis in emergency wards in Spain: variability and appropriateness analysis (aBREVIADo Project).

UNLABELLED: Most patients with acute bronchiolitis have a mild course and only require outpatient care. However, some of them have to go to emergency departments, because they have respiratory distress or feeding problems. There, they frequently receive diagnostic and therapeutic procedures. We want to know the variability and appropriateness of these procedures. A cross-sectional study (October 2007 to March 2008) was carried out on 2,430 diagnosed cases of bronchiolitis in hospital emergency departments, which required no hospitalization. An analysis of the appropriateness of the treatments was made in 2,032 cases gathered in ten departments with at least 100 cases, using as criterion the recommendations of a consensus conference. We estimated the adjusted percentages of each department. Most of the bronchiolitis were mild, in spite that they underwent multiple diagnostic and therapeutic procedures. In the acute phase, different treatments were used: inhaled beta 2 agonists (61.4%), antipyretics (17.1%), oral steroids (11.3%), and nebulized adrenaline (9.3%). In the maintenance phase, the most common treatments were: inhaled beta 2 agonists (50.5%), oral steroids (17%), oral beta 2 agonists (14.9%), and antibiotics (6.1%). The 64% of the treatments used in the acute phase and the 55.9% in the maintenance phase were considered inappropriate in the appropriateness analysis; a great heterogeneity among centers was found. CONCLUSIONS: There are discrepancies between clinical practice and evidence-based management of bronchiolitis in Spanish emergency departments. Inappropriate treatments were used in more than half of patients. The wide variation between centers shows the influence of local prescribing habits and reveals the scope for improvement.

Efficacy of bladder stimulation techniques for urine collection from infants: a systematic review and metaô€€Žanalysis. / Eficacia de las técnicas de estimulación de la micción para la recogida de orina en el lactante: revisión sistemática y metanálisis.

OBJECTIVES: Collecting a urine sample from an infant is one of the most frequently performed emergency department procedures. We aimed to evaluate noninvasive bladder stimulation techniques to obtain urine samples from infants. MATERIAL AND METHODS: Systematic review and meta-analysis of published experimental and observational studies indexed in MEDLINE (PubMed Central); the Cumulative Index of Nursing and Allied Health Literature (CINAHL); the Ibero-American index, CUIDEN; and Embase. Eligible studies had to have assessed the success rate of a technique, time until urination, level of acceptance, and risk of contamination. Comparison of a stimulation technique to nonstimulation was not necessary. RESULTS: We selected 15 studies enrolling newborns or older infants. The setting was usually an emergency department. The probability of success was 2.4-fold higher with stimulation than without it (relative risk, 2.47; 95% CI, 1.84-3.31; I2, 0%) in 2 studies. The rate of success was higher in newborns (81%; 95% CI, 72.9%-89.1%) in 6 studies totaling 331 cases (I2, 73.2%) than in older infants (51.5%; 95% CI, 35.3%-67.7%) in 9 studies with 809 cases (I2, 96.4%). The mean time required to obtain a sample was 83 (95% CI, 65-101) seconds in 10 studies (I2, 94.3%). The stimulation technique of Herreros had the highest success rate (68.4%; 95% CI, 56.2%-80.7%; I2 95,1%). CONCLUSION: New stimulation techniques for taking urine samples from infants are useful, especially in newborns. Advantages are the short time to urination, the high success rate, and the possibility of lowering the infant's levels of stress and pain.

OBJETIVO: La recogida de orina en el lactante constituye uno de los procedimientos más habituales de los servicios de urgencias. Presentamos una evaluación de las técnicas de estimulación de la micción en lactantes para la recogida no invasiva de orina. METODO: Revisión sistemática con metanálisis de estudios experimentales y observacionales publicados (PubMed, CENTRAL, CINAHL, Cuiden y EMBASE) que evalúen la tasa de éxito, el tiempo hasta la micción, el grado de aceptación y el riesgo de contaminación, en comparación o no con técnicas sin estimulación. RESULTADOS: Seleccionamos 15 estudios que incluían recién nacidos y lactantes en su mayoría atendidos en servicios de urgencias. La probabilidad de éxito es 2,4 veces mayor (RR 2,47; IC 95%: 1,84 a 3,31; 2 estudios, 234 casos; I2 0%) con estimulación que sin ella. La tasa de éxito es mayor en los recién nacidos con un 81% (IC 95% 72,9 a 89,1%; 6 estudios; 331 casos; I2 73,2%) que en los lactantes, con 51,5% (IC 95% 35,3 a 67,7%; 9 estudios; 809 casos; I2 96,4%). El tiempo medio requerido es de 83 segundos (IC 95%: 65 a 101; 10 estudios; I2 94,3%). La técnica con la mayor tasa de éxito es la de Herreros con un 68,4% (IC 95% 56,2 a 80,7%; I2 95,1%). CONCLUSIONES: Las nuevas técnicas de estimulación de la micción son una buena alternativa para la recogida de orina, especialmente para recién nacidos. Además de reducir el tiempo y aumentar el éxito de la captura, puede disminuir el estrés y el dolor del niño.

Psychological and social impact on parents of children with feeding difficulties.

OBJECTIVES: The prevalence of feeding disorders (FDs) and picky eating in children is high in our region, based on the parents' perceptions. Although organic disease or a nutritional impact is rarely observed in these children, the problem frequently has an effect on family dynamics. We aimed to estimate the impact of these disorders on the stress level, quality of life and psychological health of families. METHODS: Study of cases (FDs) and controls (healthy controls and controls with digestive disorders or other illness). We assessed parental stress and the risk of psychological distress in these families using validated scales (Parent Stress Index Short Form [PSI-SF] and Goldberg's General Health Questionnaire [GHQ-28]) and a parental opinion survey. RESULTS: We collected a total of 238 surveys, 102 corresponding to healthy controls, 88 to controls with digestive disorders and 48 to children with FDs. We found that 45.8% of parents in the FD group felt neglected by their paediatricians and 47.9% did not agree with the paediatrician's recommendations. In addition, 54.2% reported limitations to their social life, 25% problems in their relationship, 47.9% feeling judged by others (12.5% by their own partner) for how they managed mealtimes, and 37.5% having sought or considered seeking psychological support. All these problems were significantly more frequent compared to controls. Based on the GHQ-28, the risk of anxiety and depression was more frequent in parents in the FD group: 54.2% compared to the reference (adjusted odds ratio [aOR] compared to controls, 4.18; 95% confidence interval [CI], 1.96-8.87; OR compared to sick controls, 6.25; 95% CI, 2.79-13.98) and 33.3% compared to the healthy control group. They also had higher stress scores (PSI-SF) compared to the healthy control group (adjusted mean difference [AMD], 21; 95% CI, 12.19-29.81) and the sick control group (AMD, 20; 95% CI, 9.81-30.19). CONCLUSIONS: Parents of children with FDs have a high level of stress and risk of anxiety and depression, with repercussions at the social, family, couple and work levels. The relationship with the paediatrician may also be affected.

Impact of different nebulisation systems on patient comfort in bronchiolitis: a randomised controlled cross-over trial.

OBJECTIVE: To test the hypothesis that greater comfort is achieved using a nebuliser integrated into a high-flow nasal cannula (nebulisation system integrated in high-flow nasal cannula (NHF)) than using a jet nebuliser (JN), and to explore differences in analgesia requirement and the possibility of feeding during nebulisation. DESIGN: Randomised cross-over trial. SETTING: Paediatric intensive care unit. PATIENTS: Children aged <24 months diagnosed with bronchiolitis between November 2016 and May 2017. INTERVENTIONS: Nebulisations using NHF and JN. MAIN OUTCOME MEASURES: COMFORT-Behaviour Scale (CBS) and Numerical Rating Comfort Scale (NRSc) were used to measure comfort, and Numerical Rating Satisfaction Scale (NRSs) was used to assess satisfaction before, during and after nebulisation. Other variables included feeding, analgesia, need for being held and respiratory and heart rates. RESULTS: Thirty-three children with 233 nebulisations were included in the study. The median age was 3.0 (IQR 2-9) months. Comfort and satisfaction were greater with NHF than with JN. The median staff-recorded CBS, NRSc and NRSs scores for NHF versus JN were 13 (IQR 9-15) vs 17 (IQR 13-23), 8 (IQR 7-0) vs 7 (IQR 4-8), and 4 (IQR 3-4) vs 2 (IQR 2-3), respectively; and caregiver-recorded scores were 12 (IQR 10-15) vs 19 (IQR 13-24), 9 (IQR 7-10) vs 4 (IQR 1-6), and 4 (IQR 3-4) vs 2 (IQR 1-3), respectively (p<0.001). Children who received NHF had lower cardiac and respiratory rates, needed to be held less often during therapy and required less analgesia (p<0.001). CONCLUSION: Nebulisation through NHF appears to be a better alternative to JN in terms of comfort and satisfaction as well as making feeding possible during nebulisation.

Effectiveness of high-flow oxygen therapy in a second-level hospital in bronchiolitis.

INTRODUCTION: To estimate the impact of the incorporation of high-flow nasal cannule (HFNC) in patients admitted with acute bronchiolitis in a hospital without pediatric intensive care unit (PICU). MATERIAL AND METHODS: Cohort study with historical control of bronchiolitis in a second-level hospital, before (2009-2012) and after (2015-2020) the implementation of HFNC. The main outcome was the need for admission to the PICU. RESULTS: 301 patients were included. Respiratory syncytial viruses were identified in 64.7% of them and influenza viruses in 0.3%. No differences in age nor comorbility between periods were observed. The average stay was 3.67 days (standard deviation [SE] 2.10) in the first period and 4.00 days (SE 2.35) in the second. Three patients were transferred to UCIP (2.6%) before the availability of HFCN and 13 patients (9.4%) after, which supposed an important increase of the risk (relative risk 3.58; confidence interval [CI] 95%: 1.04-12.27), although not significant in adjusted analyses (Odds ratio 3.48; IC95% 0.95-12.72). A significant increase in readmission risk was also observed (from 5.3%-13.7%) and a shortening of the time to transfer. CONCLUSIONS: The incorporation of HFNC was not associated with a lower risk of transfer to PICU nor a shorter length of oxygen therapy. In the absence of evidence, that supports the effectiveness and efficiency of the HFNC and establishes its indications, we must reassess its use.

[Main changes in the «COVID-19 in paediatrics¼ clinical practice guideline]. / Principales modificaciones en la guía de práctica clínica «COVID-19 en pediatría¼.

We present a summary of the main modifications to the «COVID-19 in Paediatrics¼ clinical practice guideline made from its initial version, published in 2021, and the version published in 2022. The document was developed following the structured steps of evidence-based medicine and applying the GRADE system to synthesize the evidence, assess its quality and, when appropriate, issue graded recommendations (based on the quality of the evidence, values and preferences, the balance between benefits, risks and costs, equity and feasibility). This update also includes the modifications proposed by external reviewers.We summarised the main modifications in the following sections: epidemiology, clinical features, diagnosis, prevention, treatment and vaccines. In relation to the body of knowledge achieved in the first year of the pandemic, the literature published in the second year contributed additional data, but without substantial modifications in many of the areas. The main changes took place in the field of vaccine research. This update was completed in December 2021, coinciding with the emergence of infections by the omicron variant, so the document will need to be updated in the future.

[Are inhaled corticosteroids effective in asthma exacerbations? Evidentia praxis]. / ¿Son eficaces los corticoides inhalados en las exacerbaciones asmáticas? Evidentia praxis.

A clinical scenario is presented, from which a structured clinical question arises: In asthmatic children or adolescents with exacerbation symptoms, does the use of inhaled corticosteroids (newly instituted or base dose increased) reduce the risk of exacerbations that require systemic steroids and/or hospitalization? To answer it, we carried out a bibliographic search, with selection, evaluation and graduation of the evidence, following GRADE criteria. We did not find sufficient evidence to consider intermittent inhaled steroids as an alternative to maintenance inhaled steroids to avoid exacerbations that require the use of systemic steroids. The use of a combination of inhaled steroids with formoterol, as a rescue treatment at the onset of symptoms, is only effective when used by patients with this maintenance treatment, compared to those who only have inhaled steroids and rescue with beta2-agonists of short action; when patients already take maintenance combined therapy, combined rescue does not reduce the risk. In patients with asthma attacks attended in the emergency department, inhaled steroids compared to placebo reduce the risk of admission, but not when compared to systemic corticosteroids.

Usefulness of video recordings for validating neonatal encephalopathy exams: a population-based cohort study.

OBJECTIVE: To determine the usefulness of video recordings for validating neonatal encephalopathy (NE) exams. DESIGN: Population-based prospective cohort study. NE was assessed and recorded at 1, 3 and 5 hours after birth by the attending physician. Recordings were reviewed blindly after the recruitment period by two specialists. Outcome was assessed at 36 months of age. SETTING: Twelve intensive care units in Spain. PATIENTS: Infants of ≥35 weeks' gestational age with perinatal asphyxia. MAIN OUTCOMES MEASURES: Weighted kappa to measure disagreement between the two specialists and between the attending physician and the specialists' classification agreed on by consensus. Regression models to test the association of disagreement on NE assessment and outcome. RESULTS: Of the 32 325 liveborn infants, 217 met the inclusion criteria. Video-recordings were not available for 43 infants (20%). Weighted kappa statistic was 0.74 (95% CI 0.67 to 0.81) between the specialists and the attending physicians. Disagreement occurred in 93 of the 417 (22%) videos, specifically in 39 (14%), 43 (47%), 11 (34%) and 0 exams categorised as no, mild, moderate and severe NE, respectively. According to the specialist consensus assessment, there was disagreement on the therapeutic hypothermia decision in 10 infants.When there was consensus among the specialists assessing a more severe NE degree compared with the attending physicians in 170 infants, those infants had lower cognitive scores with a median of -5.33 points (95% CI -9.85 to -8.16; p=0.02). CONCLUSIONS: This study supports the feasibility and benefit of using video recordings to identify NE in infants with perinatal asphyxia.
