The risk of hospitalisation from RSV is not increased by co-infection in children under 24-months-of-age.

The recent pandemic prompted renewed interest in paediatric respiratory infections, including whether co-infections - particularly with RSV - have an adverse prognostic impact. We evaluated the charts of all children presenting with respiratory symptoms to our unit between October 2022 and April 2023, each of whom was subjected to a multiplex PCR assay to detect eight viral targets and one bacterial target and examine the relationships between mono- and co-infections and hospitalization outcomes. We observed that younger age and RSV infection were both associated with the need for hospitalisation and the duration of hospitalisation after adjusting for confounders. Co-infection was, however, not associated with these outcomes.   Conclusion: This real-world data add to a growing consensus that RSV increases the risk of hospitalisation, while other co-infections, except for co-infection with SARS-CoV-2, do not. Given the timeframe over which our study was conducted, only a few children had SARS-CoV-2 co-infection, so we could not confirm any significant effect from this interaction. What is Known: • RSV increases the risk of hospitalisation and the need tor ventilatory support, especially in very young children. What is New: • Younger age and RSV infection were both associated with the need for hospitalisation and the duration of hospitalisation after adjusting for confounders. • Co-infection was, however, not associated with these outcomes.

Is the short axis view of the fetal heart useful in improving the diagnostic accuracy of outlet ventricular septal defects?

OBJECTIVES: Outlet ventricular septal defects (VSDs) are usually suspected on the five-chamber view of the fetal heart; however, postnatal confirmation occurs only in a small number of cases. The aim of this study was to evaluate if the systematic assessment of the short axis view may improve the prediction of prenatally detected outlet VSDs. METHODS: Cases where isolated outlet VSD was suspected on the five-chamber view were assessed by using the short axis scanning plane for confirmation of the defect. Postnatal assessment was performed within 2 weeks from birth at our Paediatric Cardiology Unit. RESULTS: An outlet VSD was suspected at five-chamber view in 23 fetuses. Postnatal confirmation of the VSD occurred in 14 cases where the defect was prenatally detected both on the five chamber and the short axis views. VSDs were not confirmed at postnatal assessment only in two cases where outlet VSD was suspected on both views, whereas all the seven cases with a suspected VSD on the five-chamber view only turned out to be false positives. CONCLUSION: The short axis view of the fetal heart seems useful in confirming the presence of outlet VSDs. © 2016 John Wiley & Sons, Ltd.

Impact of Ethnicity on COVID-19 Related Hospitalizations in Children During the First Pandemic Wave in Northern Italy.

There is increasing evidence that black people and other minorities have a higher incidence of severe COVID-19 disease, but little is known about the situation of children, especially in Europe. In general children are less infected and if so, frequently show mild or asymptomatic disease, making conclusions difficult. We collected data on SARS-CoV-2 associated hospitalizations in a well-defined population of 550,180 children up to 15 years in five hub-centers during the "first wave" at the heart of the pandemic in Northern Italy. Among the 451,053 Italian citizens 80 were hospitalized as compared to 31 out of 99,127 foreign citizens, giving a significantly higher risk (odds ratio 1.76; 95% CI: 1.16-2.66) for the foreign children. The risk was highest for children of African ethnicity as compared to Italians with an odds ratio of 2.76 (95% CI: 1.56-4.87). None of the patients deceased. There was no significant difference in age (thou infants regardless of ethnicity had a 10-fold higher risk), sex, length of hospitalization or comorbidities, namely overweight. As bureaucratic, cultural and information barriers mostly affect preventive and adult services and considering that in contrast to other countries, in Italy pediatric care is guaranteed free of (out-of-pocket) charge to all people <16 years, and hospitals are densely spaced, access to health care seems to be a minor problem. Thus, other possible root causes are discussed. We believe that this is an unbiased starting point to understand and overcome the reasons for the higher risk those children experience.

Changing Admission Patterns in Pediatric Emergency Departments during the COVID-19 Pandemic in Italy Were Due to Reductions in Inappropriate Accesses.

During the initial phase of the national lockdown, we found that there were sharp decreases in admissions to two pediatric emergency departments (EDs) in northern Italy (Cremona and Novara). Here we present a detailed analysis of these admission patterns and types of admissions over a longer timeframe. ED admissions data were anonymously extracted from the departmental management software. Admissions data from 2019 and 2020 were analyzed and compared separately for each ED and combined. There was a 73.2% decrease in total admissions compared with the same period in 2019. With respect to admission diagnoses, there was a significant (p < 0.001) drop in infectious (-51%), respiratory (-25.5%), and nervous systems diseases (-50%) and injuries and poisoning (-17%) but not endocrine, metabolic, neoplastic, circulatory, or musculoskeletal diseases. White codes (patients with minor injuries for whom ED medical care is not required) significantly decreased by 56.3% (p < 0.001). Even if the COVID-19 pandemic represented an enormous healthcare burden in Italy, especially during the first months of the pandemic (late February to May), the workload of pediatric EDs was significantly reduced, especially for unnecessary accesses (white codes).

How often an isolated cardiac disproportion predicts a coarctation of the aorta? Single center experience and systematic review of the literature.

BACKGROUND: Cardiac disproportion is considered as an indirect sign of coarctation of the aorta (CoA). In this review, we have reassessed the positive predictive value (PPV) of such finding for a postnatal confirmation of CoA. DATA SOURCES: All cases of isolated cardiac disproportion diagnosed in the four-chamber and/or three-vessel/three-vessel and trachea views (right/left sections >1.5) were included. Postnatal cardiac findings were recorded. Additionally, a systematic literature search (PubMed, EMBASE, Cochrane library, and the reference lists of identified articles) regarding the association between antenatally detected cardiac disproportion and postnatal confirmation of CoA was performed. Data from our center were pooled with those derived from the literature. RESULTS: Ten fetuses with isolated cardiac disproportion were selected from our center and 259 from the literature review. CoA was postnatally confirmed in 101/269 (PPV 38%). PPV of antenatal cardiac findings was significantly higher in earlier gestation (23/27, 85% <26+0 weeks versus 11/39, 28%≥26+0 weeks, p < .001). No significant difference was noticed comparing ventricular disproportion with combined ventricular and great vessels disproportion (86/230 versus 15/39, p .89). DISCUSSION: Isolated cardiac disproportion has an overall chance of one in three of heralding a CoA in the neonate. The specificity of these findings is significantly higher in the second trimester.

Plasma concentrations of carbohydrates and sugar alcohols in term newborns after milk feeding.

Nonglucose carbohydrates such as galactose, mannose, and inositol play a clinically important role in fetal and neonatal nutrition, though little is known about their metabolism in the neonate. The aim of this study was to determine whether postprandial changes in plasma carbohydrate and sugar alcohol concentrations are affected by clinical variables such as postnatal age (PNA), milk type, feeding volume, or feeding duration in term newborns. Neonates (n = 26) taking intermittent enteral feedings were enrolled. Blood samples were obtained at baseline (immediately before the start of a feeding) and at 2-3 subsequent time points up to 110 min. Postprandial rise was only observed for plasma glucose concentrations [Glu] and plasma galactose concentrations [Gal] and clinical variables did not predict this change. Despite equimolar delivery in milk, the median of [Glu] rise minus [Gal] rise from baseline to second postprandial plasma sample was 674 microM (-38, 3333 microM; p < 0.0001), reflecting efficient hepatic first-pass metabolism of galactose. A significant PNA effect on [Gal] was observed such that for each day PNA there was an 18% decrease in [Gal] (p = 0.03). [Gal] are a function of PNA, suggesting maintenance of a significant ductus venosus shunt in term infants.

Free sugar and sugar alcohol concentrations in human breast milk.

OBJECTIVES: The goal was to determine the free sugars and polyols in human breast milk, both term and preterm, for comparison with formula milks. METHODS: Methodology was developed for the measurement of the free sugars and polyols in breast milk. There were 16 samples collected from women who delivered at term and 17 samples from women delivering preterm. For purposes of comparison, samples were also collected from four commercial formulas for term infants and eight from commercial formulas for preterm infants as well as one sample of cows' milk. All samples were frozen immediately and analyzed by high-performance liquid chromatography techniques. RESULTS: Except for lactose concentrations, no significant differences were detected for all other sugars and polyols between term and preterm breast milk samples. Within breast milk samples, two patterns emerged, with one group containing additional elution peaks for compounds not yet identified. A second group did not contain these compounds. There were a number of significant differences between breast milk and formulas, particularly for inositol, glycerol, glucose, and galactose. All milks contained significant concentrations of mannose. CONCLUSIONS: There are no significant differences among breast milk samples for free sugar and polyol concentrations except lactose. However, some milk contains additional peaks that could be of dietary or genetic origin. Formula milk has relatively high concentrations of glucose and galactose compared with breast milk, suggesting some lactose hydrolysis.
