Echovirus 11 lineage I and other enterovirus in hospitalized children with acute respiratory infection in Southern Italy (2022- 2023)

OBJECTIVES

A new variant of echovirus 11 (E11) infection is a major health concern in neonates. Here, we describe the clinical and virological characteristics of enterovirus (EV) infections in children hospitalized with acute respiratory infection in Southern Italy.

METHODS

Between July 2022-August 2023, 173 EV infections were identified. Demographic and clinical characteristics, comorbidities, and coinfections were analyzed. Genotypes were identified by sequencing of VP1. Whole-genome sequencing of five E11 strains was performed.

RESULTS

Case numbers peaked in July 2022, November-December 2022, and June-July 2023. Coxsackievirus A2 was identified in 36.7%, coxsackievirus B5 in 13.8%, echovirus E11 in 9.2%, and EV-D68 in 6.4% of cases. No child had critical symptoms or a severe infection. The only neonate infected by E11 recovered fully after 5 days in hospital. Phylogenetic analysis revealed that four E11 strains were closely related to divergent lineage I E11 strains identified in France and Italy.

CONCLUSIONS

The new variant of E11 was identified in children in Southern Italy. Although the cases were mild, the data suggest that transmission routes and host factors are likely to be main drivers for the development of potentially severe diseases. Systematic epidemiological/molecular surveillance will help us better understand the clinical impact of EV infections and develop preventive strategies.

Adolescent gender dysphoria management: position paper from the Italian Academy of Pediatrics, the Italian Society of Pediatrics, the Italian Society for Pediatric Endocrinology and Diabetes, the Italian Society of Adolescent Medicine and the Italian Society of Child and Adolescent Neuropsychiatry

BACKGROUND

In response to the imperative need for standardized support for adolescent Gender Dysphoria (GD), the Italian Academy of Pediatrics, in collaboration with the Italian Society of Pediatrics, the Italian Society for Pediatric Endocrinology and Diabetes, Italian Society of Adolescent Medicine and Italian Society of Child and Adolescent Neuropsychiatry is drafting a position paper. The purpose of this paper is to convey the author's opinion on the topic, offering foundational information on potential aspects of gender-affirming care and emphasizing the care and protection of children and adolescents with GD.

MAIN BODY

Recognizing that adolescents may choose interventions based on their unique needs and goals and understanding that every individual within this group has a distinct trajectory, it is crucial to ensure that each one is welcomed and supported. The approach to managing individuals with GD is a multi-stage process involving a multidisciplinary team throughout all phases. Decisions regarding treatment should be reached collaboratively by healthcare professionals and the family, while considering the unique needs and circumstances of the individual and be guided by scientific evidence rather than biases or ideologies. Politicians and high court judges should address discrimination based on gender identity in legislation and support service development that aligns with the needs of young people. It is essential to establish accredited multidisciplinary centers equipped with the requisite skills and experience to effectively manage adolescents with GD, thereby ensuring the delivery of high-quality care.

CONCLUSION

Maintaining an evidence-based approach is essential to safeguard the well-being of transgender and gender diverse adolescents.

Classic Galactosemia: Clinical and Computational Characterization of a Novel GALT Missense Variant (p.A303D) and a Literature Review

Classic galactosemia is an autosomal recessive inherited liver disorder of carbohydrate metabolism caused by deficient activity of galactose-1-phosphate uridylyltransferase (GALT). While a galactose-restricted diet is lifesaving, most patients still develop long-term complications. In this study, we report on a two-week-old female patient who is a compound heterozygote for a known pathogenic variant (p.K285N) and a novel missense variant (p.A303D) in the GALT gene. Segregation analysis showed that the patient inherited the p.K285N pathogenic variant from her father and the p.A303D variant from her mother. A bioinformatics analysis to predict the impact of the p.A303D missense variant on the structure and stability of the GALT protein revealed that it may be pathogenic. Based on this finding, we performed a literature review of all GALT missense variants identified in homozygous and compound heterozygous galactosemia patients carrying the p.K285N pathogenic variant to explore their molecular effects on the clinical phenotype of the disease. Our analysis revealed that these missense variants are responsible for a wide range of molecular defects. This study expands the clinical and mutational spectrum in classic galactosemia and reinforces the importance of understanding the molecular consequences of genetic variants to incorporate genetic analysis into clinical care.

Incorrect Feeding Practices, Dietary Diversity Determinants and Nutritional Status in Children Aged 6-23 Months: An Observational Study in Rural Angola

BACKGROUND

More than a quarter of children who are affected by severe acute undernutrition reside in Sub-Saharan Africa. Incorrect feeding practices have a negative impact on a child's health in both the short and the long term, and the interval from conception to two years is the most critical for the development of undernutrition-related complications. These first 1000 days of life also represent an "opportunity window" for early interventions, hence, having a clear insight into dietary habits and the determinants of diet quality is fundamental to improving nutritional counseling practices.

OBJECTIVES

To investigate incorrect feeding practices, dietary diversity determinants and nutritional status in children aged 6-23 months.

METHODS

Prospective quali-quantitative observational study conducted at the Missionary Catholic Hospital of Chiulo (Angola) from March to April 2023.

RESULTS

Of 250 children, global acute malnutrition affected 25.2% and was associated with starting complementary feeding at <4 months of age (p = 0.007) and not achieving the minimum meal frequency (p < 0.0001). Minimum dietary diversity was found in 11.2%, minimum meal frequency was experienced by 72.8%, and the minimum acceptable diet was found in 11.2% of participants. The minimum dietary diversity was reached only by households with access to food from five or more major food groups (p = 0.007) or the money to buy food from five or more major food groups (p = 0.008) and was higher in households where the householder had a higher educational level (p = 0.002). Regarding the determinants linked to family traditions and beliefs, the main religion-associated beliefs concerned the impurity of pork (n = 25) and fish (n = 8), while eggs (n = 19) and cow milk (n = 8) were the main food types that were deemed harmful for children.

CONCLUSIONS

Although some factors (economic and religious) may be difficult to overcome, other factors linked to erroneous beliefs (dangerous foods) or incorrect feeding practices (early weaning and an incorrect frequency of meals) can be targeted, to improve the effectiveness of nutritional counseling practices.

Incidence and prevalence of congenital clubfoot in Apulia: a regional model for future prospective national studies

BACKGROUND

Congenital clubfoot is a fairly common and severe congenital malformation, most often of idiopathic origin. A smaller percentage of cases is related to chromosomal abnormalities and genetic syndromes. It is estimated that 0.5/1000 newborns are affected worldwide, with a male to female ratio of 2:1 and greater distribution in developing countries (80%). The "European Surveillance of Congenital Anomalies (EUROCAT)" reported clubfoot prevalence in European newborns, but data regarding Italy are missing or poor. We aim to provide detailed data on clubfoot incidence according to the Apulian Regional Registry on Congenital Malformations and to report current knowledge on clubfoot genetic factors.

METHODS

We extrapolated data from the Regional Registry of Congenital Malformations to evaluate incidence and prevalence of congenital clubfoot in Apulia, Italy over a period of four years (2015-2018). We also performed a narrative review focusing on genetic mutations leading to congenital clubfoot.

RESULTS

Over the period from 2015 to 2018 in Apulia, Italy, 124,017 births were recorded and 209 cases of clubfoot were found, accounting for an incidence rate of 1.7/1,000 and a prevalence rate of 1.6/1,000. Six families of genes have been reported to have an etiopathogenetic role on congenital clubfoot.

CONCLUSIONS

Incidence and prevalence of congenital clubfoot in Apulia, Italy, are comparable with those reported in the other Italian regions but higher than those reported in previous studies from Europe. Genetic studies to better classify congenital clubfoot in either syndromic or isolated forms are desirable.

SLAB51 Multi-Strain Probiotic Formula Increases Oxygenation in Oxygen-Treated Preterm Infants

Preterm infants are at risk of hypoxia and hyperoxia because of the immaturity of their respiratory and antioxidant systems, linked to increased morbidity and mortality. This study aimed to evaluate the efficacy of a single administration of the SLAB51 probiotic formula in improving oxygenation in respiratory distress syndrome (RDS)-affected premature babies, thus reducing their need for oxygen administration. Additionally, the capability of SLAB51 in activating the factor-erythroid 2-related factor (Nrf2) responsible for antioxidant responses was evaluated in vitro. In two groups of oxygen-treated preterm infants with similar SaO2 values, SLAB51 or a placebo was given. After two hours, the SLAB51-treated group showed a significant increase in SaO2 levels and the SaO2/FiO2 ratio, while the control group showed no changes. Significantly increased Nrf2 activation was observed in intestinal epithelial cells (IECs) exposed to SLAB51 lysates. In preterm infants, we confirmed the previously observed SLAB51's "oxygen-sparing effect", permitting an improvement in SaO2 levels. We also provided evidence of SLAB51's potential to enhance antioxidant responses, thus counteracting the detrimental effects of hyperoxia. Although further studies are needed to support our data, SLAB51 represents a promising approach to managing preterm infants requiring oxygen supplementation.

Autophagy increase in Merosin-Deficient Congenital Muscular Dystrophy type 1A

The autophagy process recycles dysfunctional cellular components and protein aggregates by sequestering them in autophagosomes directed to lysosomes for enzymatic degradation. A basal level of autophagy is essential for skeletal muscle maintenance. Increased autophagy occurs in several forms of muscular dystrophy and in the merosin-deficient congenital muscular dystrophy 1A mouse model (dy3k/dy3k) lacking the laminin-α2 chain. This pilot study aimed to compare autophagy marker expression and autophagosomes presence using light and electron microscopes and western blotting in diagnostic muscle biopsies from newborns affected by different congenital muscular myopathies and dystrophies. Morphological examination showed dystrophic muscle features, predominance of type 2A myofibers, accumulation of autophagosomes in the subsarcolemmal areas, increased number of autophagosomes overexpressing LC3b, Beclin-1 and ATG5, in the merosin-deficient newborn suggesting an increased autophagy. In Duchenne muscular dystrophy, nemaline myopathy, and spinal muscular atrophy the predominant accumulation of p62+ puncta rather suggests an autophagy impairment.

How Much Is an Abortion Worth? Was a Human "Not Formed"? An Italian Proposal

INTRODUCTION

"Human capital" is defined as an integration of innate skills and knowledge acquired by investing in the formation of an individual; it is a real "capital" that pays off in the long term. In the Italian legal system, a human being is recognised as a "person" from the moment of birth. This determines the acquisition of the personal rights of an individual. Necessarily, therefore, by law, a fetus does not own such rights; nevertheless, it has an innate "potential" to acquire such rights after birth.

OBJECTIVE

In Italian jurisprudence, in general, the damage from a loss of a parental relationship is justified by the condition of existential emptiness caused in the family by the loss of a child. Compensation for this damage in the event of abortion due to third-party responsibility presents a non-uniform recognition in the judgements of the Italian courts, but in any case, it is almost always recognised with limitations since the emotional relationship with the lost individual is defined only in terms of "potential". Consequently, in this matter, at least two questions can be raised: (i) Is the economic estimate of abortion based on objective and standardised criteria, or is it heavily influenced by subjective evaluation? (ii) Is it possible to find standard criteria that may act as guidelines to quantify the loss of that human capital "in progress"?

METHODOLOGY

The authors try to answer these questions by analysing the different approaches to this issue adopted at an international level.

CONCLUSIONS

In conclusion, the authors propose homogeneous criteria to quantify the damage caused by abortion.

Use of Sotrovimab in a cohort of pregnant women with a high risk of COVID 19 progression: a single-center experience

Neutralizing monoclonal antibodies (mAbs) have been shown to reduce disease progression in patients with underlying predisposing conditions. Unfortunately, there is no evidence on the use of Sotrovimab in pregnant women. Herein we present a case series of pregnant women who received mAbs with Sotrovimab following the Italian Drug Agency (AIFA) indications. Since February 1, 2022 all pregnant women - regardless of gestational age - admitted to Obstetrics & Gynaecology of Policlinico University of Bari, with positive nasopharyngeal NAAT for SARS-CoV-2 were screened according to the AIFA indications for Sotrovimab and, if eligible, were proposed for treatment. Data on COVID-19, pregnancy, delivery, newborn outcomes, and adverse events were collected. From February 1 to May 15, 2022, 58 pregnant women were screened. Fifty (86%) patients were eligible, 19 of them (32.7%) denied their consent, in 18 cases (31%), the drug was temporarily unavailable, and the remaining 13 (22%) were treated with Sotrovimab. Out of these 13 patients, 6 (46%) were in the 3rd and 7 (54%) in the 2nd trimester of pregnancy. None of the 13 patients experienced adverse reactions due to Sotrovimab and all had a good clinical outcome. Furthermore, evaluating pre- and post-infusion clinical status and hematochemical profile, a reduction in D-dimers and an increase in SARS-CoV-2 antibodies (p < 0.01) during the 72 h following the infusion were observed. Our data, the first on the use of Sotrovimab in pregnant women, showed the safety and efficacy drug profile and its potential crucial role in preventing COVID-19 disease progression.

Do social media interventions increase vaccine uptake?

Introduction

The Italian mass COVID-19 vaccination campaign has included children aged 5-11 years as part of the target population since December 2021. One of the biggest challenges to vaccine uptake was vaccine hesitancy among parents and children's caregivers. Primary care pediatricians (PCPs), as the first point of contact between the National Health Service (NHS) and parents/caretakers, initiated various communication strategies to tackle this hesitancy. This study aims to evaluate the impact of a PCP-led social media intervention and a digital reminder service (DRS) on parental hesitancy regarding vaccinating their 5-11-year-old children against COVID-19.

Methods

A prospective cohort study was designed, and the chosen target populations were parents and caretakers of children aged 5-11 years. Two PCP cohorts were recruited. The first group received a social media intervention and a DRS; while the second group did not. Both cohorts had access to traditional face-to-face and telephone-based counseling. The vaccination coverage rate in the two groups was evaluated.

Results

A total of 600 children were enrolled. The exposed cohort (277 patients) received social media intervention, DRS, and counseling options (face-to-face and telephone-based), whereas the non-exposed cohort (323 patients) received only counseling options. In total, 89 patients from the exposed cohort did not receive any dose of the COVID-19 vaccine (32.5%), 165 were fully immunized (59.5%), and 23 received only one dose (8.5%). A total of 150 non-exposed patients did not receive any dose of the COVID-19 vaccine (47%), 147 were fully immunized (45.5%), and 24 only received one dose (7.4%). The difference between the two groups was statistically significant (chi square = 11.5016; p = 0.0006).

Conclusion

Social media and DRS interventions had a positive impact on vaccine uptake and may be helpful in tackling vaccine hesitancy. Better-designed studies are needed to corroborate these findings.

Lumbar Puncture and Meningitis in Infants with Proven Early- or Late-Onset Sepsis: An Italian Prospective Multicenter Observational Study

Background: To evaluate the rates of lumbar puncture (LP) in infants with culture-proven sepsis. Study design: We prospectively enrolled 400 infants with early- or late-onset sepsis due to Group B streptococcus (GBS) or Eschericha coli, diagnosed within 90 days of life. Rates of LP and potential variables associated with LP performance were evaluated. Moreover, cerebrospinal fluid (CSF) characteristics and results of the molecular analysis were investigated. Results: LP was performed in 228/400 (57.0%) infants; 123/228 LPs (53.9%) were performed after antibiotic initiation, hampering the ability to identify the pathogen in the CSF culture. However, polymerase chain reaction increased the probability of positive results of CSF analysis compared to microbiological culture (28/79, 35.4% vs. 14/79, 17.7%, p = 0.001). Severe clinical presentation and GBS infection were associated with higher LP rates. The rate of meningitis was 28.5% (65/228). Conclusions: Rates of LP are low in culture-proven neonatal sepsis and antibiotics are frequently given before LP is carried out. Thus meningitis may be underestimated, and the chances of giving an effective therapy to the newborn are reduced. LP should be performed before the start of antibiotics when there is a clinical suspicion of infection.

Hospitalization for bronchiolitis in children aged ≤ 1year, Southern Italy, year 2021: need for new preventive strategies?

BACKGROUND

Bronchiolitis is a major cause of hospitalization in infants, particularly in the first six months of life, with approximately 60-80% of admissions due to respiratory syncytial virus (RSV) infection. Currently, no prophylactic options are available for healthy infants. The present study aimed at describing the demographic, clinical, and epidemiological characteristics of infants hospitalized for bronchiolitis in the Apulia region of Italy in 2021.

METHODS

From January to December 2021, data on children aged 0-12 months admitted for bronchiolitis in nine neonatal or pediatric units covering 61% of pediatric beds of hospitals in the Apulia region of Italy were analyzed. Demographic data, comorbidities, need for oxygen support, length of hospital stay, palivizumab administration, and outcomes were collected. For the purpose of the analysis, patients were divided into those aged 0-3 months and > 3 months. A multivariate logistic regression model was used to explore associations between the need for oxygen support and sex, age, comorbidities, history of prematurity, length of hospital stay, and palivizumab administration.

RESULTS

This study included 349 children aged 0-12 months admitted for bronchiolitis, with a peak of hospitalization in November (7.4 cases/1,000 children). Of these patients, 70.5% were RSV positive, 80.2% were aged 0-3 months, and 73.1% required oxygen support. Moreover, 34.9% required observation in the sub-intensive care unit, and 12.9% in the intensive care unit. Of the infants who required intensive care, 96.9% were aged 0-3 months and 78.8% were born at term. Three patients required mechanical ventilation and one, who required Extra Corporeal Membrane Oxygenation, died. Children aged 0-3 months were more likely to show dyspnea, need oxygen support, and have a longer hospital stay.

CONCLUSIONS

The present study showed that almost all of the children who required intensive care support were aged ≤ 3 months and most were born at term. Therefore, this age group remains the highest risk group for severe bronchiolitis. Preventive measures such as single-dose monoclonal antibody immunoprophylaxis, and maternal and childhood vaccination against RSV, may reduce the high public health burden of bronchiolitis.

Timing of Symptoms of Early-Onset Sepsis after Intrapartum Antibiotic Prophylaxis: Can It Inform the Neonatal Management?

The effectiveness of "inadequate" intrapartum antibiotic prophylaxis (IAP administered < 4 h prior to delivery) in preventing early-onset sepsis (EOS) is debated. Italian prospective surveillance cohort data (2003-2022) were used to study the type and duration of IAP according to the timing of symptoms onset of group B streptococcus (GBS) and E. coli culture-confirmed EOS cases. IAP was defined "active" when the pathogen yielded in cultures was susceptible. We identified 263 EOS cases (GBS = 191; E. coli = 72). Among GBS EOS, 25% had received IAP (always active when beta-lactams were administered). Most IAP-exposed neonates with GBS were symptomatic at birth (67%) or remained asymptomatic (25%), regardless of IAP duration. Among E. coli EOS, 60% were IAP-exposed. However, IAP was active in only 8% of cases, and these newborns remained asymptomatic or presented with symptoms prior to 6 h of life. In contrast, most newborns exposed to an "inactive" IAP (52%) developed symptoms from 1 to >48 h of life. The key element to define IAP "adequate" seems the pathogen's antimicrobial susceptibility rather than its duration. Newborns exposed to an active antimicrobial (as frequently occurs with GBS infections), who remain asymptomatic in the first 6 h of life, are likely uninfected. Because E. coli isolates are often unsusceptible to beta-lactam antibiotics, IAP-exposed neonates frequently develop symptoms of EOS after birth, up to 48 h of life and beyond.

What Have We Learned from Patients Who Have Arboleda-Tham Syndrome Due to a De Novo KAT6A Pathogenic Variant with Impaired Histone Acetyltransferase Function? A Precise Clinical Description May Be Critical for Genetic Testing Approach and Final Diagnosis

Pathogenic variants in genes are involved in histone acetylation and deacetylation resulting in congenital anomalies, with most patients displaying a neurodevelopmental disorder and dysmorphism. Arboleda-Tham syndrome caused by pathogenic variants in KAT6A (Lysine Acetyltransferase 6A; OMIM 601408) has been recently described as a new neurodevelopmental disorder. Herein, we describe a patient characterized by complex phenotype subsequently diagnosed using the clinical exome sequencing (CES) with Arboleda-Tham syndrome (ARTHS; OMIM 616268). The analysis revealed the presence of de novo pathogenic variant in KAT6A gene, a nucleotide c.3385C>T substitution that introduces a premature termination codon (p.Arg1129*). The need for straight multidisciplinary collaboration and accurate clinical description findings (bowel obstruction/megacolon/intestinal malrotation) was emphasized, together with the utility of CES in establishing an etiological basis in clinical and genetical heterogeneous conditions. Therefore, considering the phenotypic characteristics, the condition’s rarity and the reviewed literature, we propose additional diagnostic criteria that could help in the development of future clinical diagnostic guidelines. This was possible thanks to objective examinations performed during the long follow-up period, which permitted scrupulous registration of phenotypic changes over time to further assess this rare disorder. Finally, given that different genetic syndromes are associated with distinct genomic DNA methylation patterns used for diagnostic testing and/or as biomarker of disease, a specific episignature for ARTHS has been identified.

Analysis of Antibiotic Exposure and Early-Onset Neonatal Sepsis in Europe, North America, and Australia

IMPORTANCE

Appropriate use of antibiotics is life-saving in neonatal early-onset sepsis (EOS), but overuse of antibiotics is associated with antimicrobial resistance and long-term adverse outcomes. Large international studies quantifying early-life antibiotic exposure along with EOS incidence are needed to provide a basis for future interventions aimed at safely reducing neonatal antibiotic exposure.

OBJECTIVE

To compare early postnatal exposure to antibiotics, incidence of EOS, and mortality among different networks in high-income countries.

DESIGN, SETTING, AND PARTICIPANTS

This is a retrospective, cross-sectional study of late-preterm and full-term neonates born between January 1, 2014, and December 31, 2018, in 13 hospital-based or population-based networks from 11 countries in Europe and North America and Australia. The study included all infants born alive at a gestational age greater than or equal to 34 weeks in the participating networks. Data were analyzed from October 2021 to March 2022.

EXPOSURES

Exposure to antibiotics started in the first postnatal week.

MAIN OUTCOMES AND MEASURES

The main outcomes were the proportion of late-preterm and full-term neonates receiving intravenous antibiotics, the duration of antibiotic treatment, the incidence of culture-proven EOS, and all-cause and EOS-associated mortality.

RESULTS

A total of 757 979 late-preterm and full-term neonates were born in the participating networks during the study period; 21 703 neonates (2.86%; 95% CI, 2.83%-2.90%), including 12 886 boys (59.4%) with a median (IQR) gestational age of 39 (36-40) weeks and median (IQR) birth weight of 3250 (2750-3750) g, received intravenous antibiotics during the first postnatal week. The proportion of neonates started on antibiotics ranged from 1.18% to 12.45% among networks. The median (IQR) duration of treatment was 9 (7-14) days for neonates with EOS and 4 (3-6) days for those without EOS. This led to an antibiotic exposure of 135 days per 1000 live births (range across networks, 54-491 days per 1000 live births). The incidence of EOS was 0.49 cases per 1000 live births (range, 0.18-1.45 cases per 1000 live births). EOS-associated mortality was 3.20% (12 of 375 neonates; range, 0.00%-12.00%). For each case of EOS, 58 neonates were started on antibiotics and 273 antibiotic days were administered.

CONCLUSIONS AND RELEVANCE

The findings of this study suggest that antibiotic exposure during the first postnatal week is disproportionate compared with the burden of EOS and that there are wide (up to 9-fold) variations internationally. This study defined a set of indicators reporting on both dimensions to facilitate benchmarking and future interventions aimed at safely reducing antibiotic exposure in early life.

Lingual laser frenotomy in newborns with ankyloglossia: a prospective cohort study

Background

The study aims to describe the lingual laser frenotomy perioperative protocol for newborns with ankyloglossia with or without breastfeeding difficulties developed by Odontostomatology and Neonatology and Neonatal Intensive Care Units of the Aldo Moro University of Bari.

Methods

Authors carried out a prospective observational cohort study. Newborns with ankyloglossia (classified by using both Coryllos’ and Hazelbaker’s criteria) with or without difficult breastfeeding (according to Infant Breastfeeding Assessment Tool) underwent diode laser frenotomy (800 ± 10 nm; 5 W; continuous wave mode; contact technique; under topical anesthesia) and follow-up visits after seven and thirty days postoperatively. The authors analyzed as main outcomes the perioperative pain intensity measured by the C.R.I.E.S. scale, the occurrence of complications and quality of healing, the quality of breastfeeding, newborn’s postoperative weight gain, maternal nipple pain, and the presence of lesions as secondary outcomes.

Results

Fifty-six newborns were included in the current study. Intraoperative mean pain intensity was 5.7 ± 0.5 points, resolved within thirty postoperative minutes. Observed complications were mild punctuating bleeding, carbonization of the irradiated site, and transitory restlessness. All wounds were completely healed within the thirtieth postoperative day. During follow-up, a significant breastfeeding improvement was evident with satisfactory newborns’ weight gain and a significant reduction of nipple pain and lesions (p < .05).

Conclusion

Our lingual laser frenotomy protocol provided significant breastfeeding improvement in the mother-newborn dyads with low intraoperative pain and no significant complications.

Complementary feeding in preterm infants: a position paper by Italian neonatal, paediatric and paediatric gastroenterology joint societies

Nutrition in the first 1000 days of life is essential to ensure appropriate growth rates, prevent adverse short- and long-term outcomes, and allow physiologic neurocognitive development. Appropriate management of early nutritional needs is particularly crucial for preterm infants. Although the impact of early nutrition on health outcomes in preterm infants is well established, evidence-based recommendations on complementary feeding for preterm neonates and especially extremely low birth weight and extremely low gestational age neonates are still lacking. In the present position paper we performed a narrative review to summarize current evidence regarding complementary feeding in preterm neonates and draw recommendation shared by joint societies (SIP, SIN and SIGENP) for paediatricians, healthcare providers and families with the final aim to reduce the variability of attitude and timing among professionals.

Congenital hypothyroidism after newborn screening program reorganization in the Apulia region

Background

Congenital hypothyroidism (CH) is the most frequent congenital endocrine disorder. The purpose of the present study was to evaluate the incidence and etiological classification of CH in Apulia in a three-year period according to the reorganization of the regional screening program in a single central laboratory, as well as to analyze the growth characteristics and the associated risk factors of the CH newborns diagnosed during the study period.

Methods

Data derived from the reorganization of the newborn screening program for CH in a single central laboratory that collects dried blood spot (DBS) from 27 Maternity Hospitals are analyzed over a three-year period. Birth weight and length, daily dose of L-T4 at specific key points (3, 6, 12 and 18 months, 2, 2.5 and 3 years) were also obtained from medical records of the CH newborns during the study period and calculated as standard deviation score (SDS).

Results

The screening program diagnosed 90 newborns with confirmed CH (incidence 1:990; recall rate: 3.6%). In detail, 75.6% newborns had an eutopic thyroid, and 24.4% had thyroid dysgenesis; 33 out of the 90 newborns (36.6%) had one or more risk factors. Among these, the multiple pregnancies are the most important because they tripled the risk of CH. At diagnosis, TSH levels were different between patients with dysgenesis and those with an eutopic thyroid (p = 0.005). Treatment was started at a mean of 18.5 ± 12.8 days of life. The mean starting dose of levothyroxine (L-T4) was 11.38 ± 2.46 μg/kg/day.

Conclusions

The results of these study show an increase of CH cases in newborns with an eutopic thyroid compared to the traditional classification. The centralization of the screening program allows a closer cooperation between laboratory and clinical centers and facilitates the implementation of appropriate diagnostic evaluations and timely initiation of treatment, with positive effects on the management of the condition.

Mediterranean Diet in Developmental Age: A Narrative Review of Current Evidences and Research Gaps

Numerous studies in recent decades have shown that Mediterranean diet (MD) can reduce the risk of developing obesity in pediatric patients. The current narrative review summarizes recent evidence regarding the impact of MD across the different stages of child development, starting from fetal development, analyzing breastfeeding and weaning, through childhood up to adolescence, highlighting the gaps in knowledge for each age group. A literature search covering evidence published between 1 January 2000 and 1 March 2022 and concerning children only was conducted using multiple keywords and standardized terminology in PubMed database. A lack of scientific evidence about MD adherence concerns the age group undergoing weaning, thus between 6 months and one year of life. In the other age groups, adherence to MD and its beneficial effects in terms of obesity prevention has been extensively investigated, however, there are still few studies that correlate this dietary style with the incidence of non-communicable diseases. Furthermore, research on multi-intervention strategy should be implemented, especially regarding the role of education of children and families in taking up this healthy dietary style.

COVID-19 Vaccination in Italian Children: The Limits of Parental Rights

SARS-CoV-2 vaccination campaigns initially targeted the adult population. After the authorization of the main agencies, including the EMA (European Medicines Agency), the European Vaccination Plan now involves young people between the ages of 12-17 and 5-11. In assessing the child's "best interests", the refusal of vaccination by parents or guardians, in addition to the increased circulation of the virus, is responsible for the risk of social distancing. This reduction in social contacts, particularly during very sensitive ages such as adolescence, has been linked to the increased incidence of psychiatric illness, a significant reason for extending vaccination against SARS-CoV-2 in these younger children. One may consider that government should issue a law that allows the child to decide on the vaccination plan, even without the consent of the parents or guardians, without the need for a judge's ruling. The availability of the child should be the point of reference, according to the National Bioethics Committee, for consent to vaccination. The authors investigate the subject in depth in order to counteract vaccination hesitation, and promote the dissemination of correct scientific information, using every different possible communication tool, as well as social networks and schools.

Nutritional impairment of neonates with epidermolysis bullosa: a retrospective study

BACKGROUND

Epidermolysis bullosa (EB) is a highly invalidating genodermatosis characterized by skin and mucosa fragility and blister-formation caused by mutations of genes encoding components of the cutaneous basement membrane zone. Nutritional impairment is one of the main complications of all forms of EB, having a huge impact on growth, pubertal development, wound healing, resistance to infections and quality of life.

METHODS

In our study we have retrospectively evaluated 17 children with EB to define whether nutritional impairment in those patients is already present in the neonatal period. As secondary outcomes we considered nutritional status differences among EB subtypes and relative percentages of underweight infants at birth, first and third month. Moreover, information concerning feeding modality, possible complications were also collected, as well as cutaneous or systemic infections and duration of hospital stay.

RESULTS

Our study demonstrated that nutritional impairment of neonates with EB has an early onset since as at first month 35% of patients were below 5th centile for weight-for-age, and 94% were below the 50th percentile. Moreover, the number of infants at one month of life <5th centile for weight-for-age was significantly higher compared to birth. The nutritional status is also heavily related to the occurrence of complications, in particular infections; therefore, the prevention of these complications must play a central role in the treatment of these infants, also to avoid any nutritional impairment.

CONCLUSIONS

Nutritional status of neonates with EB seems to be compromised already during the first month of life and it is heavily related to the occurrence of infections; therefore, the prevention of these complications must play a central role in the treatment of these infants, also to avoid any nutritional impairment.

Macronutrients and Micronutrients in Parenteral Nutrition for Preterm Newborns: A Narrative Review

Preterm neonates display a high risk of postnatal malnutrition, especially at very low gestational ages, because nutritional stores are less in younger preterm infants. For this reason nutrition and growth in early life play a pivotal role in the establishment of the long-term health of premature infants. Nutritional care for preterm neonates remains a challenge in clinical practice. According to the recent and latest recommendations from ESPGHAN, at birth, water intake of 70–80 mL/kg/day is suggested, progressively increasing to 150 mL/kg/day by the end of the first week of life, along with a calorie intake of 120 kcal/kg/day and a minimum protein intake of 2.5–3 g/kg/day. Regarding glucose intake, an infusion rate of 3–5 mg/kg/min is recommended, but VLBW and ELBW preterm neonates may require up to 12 mg/kg/min. In preterm infants, lipid emulsions can be started immediately after birth at a dosage of 0.5–1 g/kg/day. However, some authors have recently shown that it is not always possible to achieve optimal and recommended nutrition, due to the complexity of the daily management of premature infants, especially if extremely preterm. It would be desirable if multicenter randomized controlled trials were designed to explore the effect of early nutrition and growth on long-term health.

Pregnancy Complications, Correlation With Placental Pathology and Neonatal Outcomes

Purpose

We aimed to clarify and contribute to a better comprehension of associations and correlations between placental histological findings, pregnancy evolution, and neonatal outcomes.

Study Design

This is a longitudinal and prospective observational study, performed between May 2015 and May 2019, on 506 pregnant women. Clinical data related to pregnancy outcome, neonatal health status, and placental histology were primarily collected. Twin pregnancies or malformed newborns were excluded and therefore the study was conducted on 439 cases. These cases have been then subdivided into the following study groups: (a) 282 placentas from pathological pregnancies; and, (b) a control group of 157 pregnancies over 33 weeks of gestational age, defined as physiological or normal pregnancies due to the absence of maternal, fetal, and early neonatal pathologies, most of which had undergone elective cesarean section for maternal or fetal indication.

Results

A normal placenta was present in 57.5% of normal pregnancies and in 42.5% of pathological pregnancies. In contrast, placental pathology was present in 26.2% of normal pregnancies and 73.8% of pathological pregnancies. Comparison of the neonatal health status with the pregnancy outcome showed that, among the 191 newborns classified as normal, 98 (51.3%) were born from a normal pregnancy, while 93 (48.7%) were born from mothers with a pathological pregnancy. Among the 248 pathological infants, 59 (23.8%) were born from a mother with a normal pregnancy, while 189 (76.2%) were born from pregnancies defined as pathological.

Conclusion

Placental histology must be better understood in the context of natural history of disease. Retrospective awareness of placental damage is useful in prevention in successive pregnancy, but their early identification in the evolving pregnancy could help in association with biological markers or more sophisticated instruments for early diagnosis.

Probiotics and Functional Gastrointestinal Disorders in Pediatric Age: A Narrative Review

Assessment and management of pain are essential components of pediatric care. Pain in pediatric age is characterized by relevant health and socio-economic consequences due to parental concern, medicalization, and long-term physical and psychological impact in children. Pathophysiological mechanisms of nociception include several pathways in which also individual perception and gut-brain axis seem to be involved. In this narrative review, we analyze the rational and the current clinical findings of probiotic use in the management of functional gastrointestinal disorders (FGID) in pediatric age, with special focus on infantile colic, irritable bowel syndrome, constipation, and gastroesophageal reflux. Some specific probiotics showed a significant reduction in crying and fussing compared to placebo in breastfed infants with colic, although their exact mechanism of action in this disorder remains poorly understood. In irritable bowel syndrome, a limited number of studies showed that specific strains of probiotics can improve abdominal pain/discomfort and bloating/gassiness, although data are still scarce. As for constipation, whilst some strains appear to reduce the number of hard stools in constipated children, the evidence is not adequate to support the use of probiotics in the management of functional constipation. Similarly, although some probiotic strains could promote gastric emptying with a potential improvement of functional symptoms related to gastroesophageal reflux, current evidence is insufficient to provide any specific recommendation for the prevention or treatment of gastroesophageal reflux. In conclusion, probiotics have been proposed as part of management of pain in functional gastrointestinal disorders in pediatric age, but mechanisms are still poorly understood and evidence to guide clinical practice is currently inadequate.

COVID-19 Infection in Pregnancy: Obstetrical Risk Factors and Neonatal Outcomes-A Monocentric, Single-Cohort Study

The effects of coronavirus disease 2019 caused by severe acute respiratory syndrome coronavirus 2 on pregnant women and neonates are mainly unknown, since limited data are available in the literature. We conducted a monocentric and cross-sectional study enrolling 122 un-vaccinated pregnant women with COVID-19 infection tested by RT-PCR nasopharyngeal swab. Only 4.1% of the patients had severe COVID-19 symptoms together with major respiratory symptoms and intensive care unit admission, whereas 35.25% of women had comorbidities and two-thirds of them were overweight or obese. COVID-19 was detected mainly in the third trimester (98.36%) and multiparous women (59.02%). The mode of delivery was influenced by mild-severe COVID-19 symptoms, with a higher number of urgent or emergent cesarean sections than spontaneous or operative vaginal births. Preterm births were associated with high BMI, mode of delivery (higher among cesarean sections), nulliparity, and severe COVID-19 symptoms. In cases of severe COVID-19 symptoms, there was a higher rate of respiratory distress syndrome among newborns. In the end, only the presence of a severe COVID-19 infection worsened the obstetrical and neonatal outcomes, with higher rates of urgent or emergent cesarean section, preterm births, and neonatal respiratory distress syndrome.

Universal Newborn Screening for Congenital Cytomegalovirus Infection - From Infant to Maternal Infection: A Prospective Multicenter Study

INTRODUCTION

Most infants at risk for cytomegalovirus (CMV)-associated sensorineural hearing loss (SNHL) are unrecognized because of the absence of a universal neonatal CMV screening. The search of CMV-DNA by molecular methods in salivary swabs was demonstrated to be a reliable approach. This study describes the results obtained by carrying out a universal screening for congenital CMV (cCMV) infection including all live-born newborns in three Italian sites, as well as the therapeutic interventions and clinical outcome of the CMV-infected neonates. Moreover, CMV maternal infection's characteristics were evaluated.

METHODS

To confirm or exclude cCMV infection, a CMV-DNA-positive result on a first salivary swab was followed by repeated saliva and urine samples collected within 21 days of age. Breast milk samples were also collected. The search of CMV-DNA was performed with a single automated quantitative commercial real-time PCR assay, regardless of the type of samples used.

RESULTS

A total of 3,151 newborns were enrolled; 21 (0.66%) of them were congenitally infected (median saliva viral load at screening, 6.65 [range, 5.03-7.17] log₁₀ IU/ml). Very low/low viral load in screening saliva samples (median value, 1.87 [range, 1.14-2.59] log₁₀ IU/ml) was associated with false-positive results (n = 54; 1.7%). CMV-DNA was detected in almost half of the breast milk samples of mother-infant pairs with a false-positive result, suggesting that contamination from breast milk may not be the only explanation in the study population. cCMV infection confirmation with the search of CMV-DNA in a urine sample proved to be the gold standard strategy, since false-positive results were observed in 4/54 (7.5%) of the repeated saliva samples. Symptomatic cCMV infection was observed in 3/21 (14.3%) infants; notably, one (4.7%) developed moderate unilateral SNHL at 5 months after birth. Finally, two symptomatic cCMV infections were associated with primary maternal infection acquired in the first trimester of gestation; one newborn with severe cCMV symptoms was born to a mother with no CMV checkups in pregnancy.

CONCLUSION

Without universal neonatal CMV screening, some infected infants who develop late neurological sequelae may not be recognized and, consequently, they are not able to benefit early from instrumental and therapeutic interventions to limit and/or treat CMV disease.

Social Media Interventions Strengthened COVID-19 Immunization Campaign

BACKGROUND

Since The Italian Medicines Agency (AIFA) has recommended the COVID-19 vaccine Comirnaty in children aged 5-11, the immunization campaign faced vaccine hesitancy in parents. Social media are emerging as leading information source that could play a significant role to counteract vaccine hesitancy, influencing parents' opinions and perceptions. Our aim was to evaluate the coverage of the COVID-19 vaccine Comirnaty in a cohort of children aged 5-11 whose families have been counseled to use Social Media to counteract vaccine hesitancy.

METHODS

All parents of children aged 5-11 in a primary care setting were instructed by their pediatrician to get accurate information about the COVID-19 vaccine from a Facebook page. Active calls to vaccinate children were also scheduled through messaging services Pediatotem and Whatsapp. Vaccination rates of children in the study were assessed with an electronic database and compared to both regional and national child vaccination rates.

RESULTS

Coverage of 277 children aged 5-11 was analyzed from 16 December 2021 to 31 January 2022. A total of 62.4% (173/277) of enrolled children received the 1st dose of COVID-19 vaccine Comirnaty and 39.7% (110/277) the 2nd dose. Coverage rates were higher compared both to the regional population (1st dose: 48.8%, 2nd dose: 24.6%; p = 0.001) and national population (1st dose: 32.1%, 2nd dose: 13.8%; p < 0.001).

CONCLUSION

Increasing vaccine confidence using Social Media interventions have a positive impact on vaccination acceptance of parents.

Survival of infants treated with CKRT: comparing adapted adult platforms with the Carpediem™

BACKGROUND

The most severely ill neonates and infants with AKI who need kidney replacement therapy have had to rely upon peritoneal dialysis, or adaptations of veno-venous continuous kidney replacement therapy (CKRT) devices for adults. Data from the Prospective Pediatric CRRT (ppCRRT) registry observed children < 10 kg had a lower survival rate than children > 10 kg (44% vs. 64%, p < 0.001). A CKRT device designed specifically for small children could improve outcomes. The Cardio-Renal Pediatric Dialysis Emergency Machine (CARPEDIEM™) is specifically dedicated to providing CKRT for newborns and small infants.

METHODS

We performed a retrospective cohort analysis comparing patient severity of illness and outcomes between the ppCRRT and CARPEDIEM registries, involving 6 Italian pediatric intensive care units. Thirty-eight subjects from the CARPEDIEM registry and 84 subjects from the ppCRRT registry < 10 kg were screened for comparison. We compared patient outcomes with a weight-matched cohort (< 5 kg) of 34 patients from the CARPEDIEM registry and 48 patients from the ppCRRT registry.

RESULTS

The ppCRRT subjects had higher rates of vasoactive medication at CKRT initiation. Survival to CKRT termination was higher for CARPEDIEM subjects (33/34 vs. 21/48, p < 0.0001). Multivariable logistic regression showed that CARPEDIEM registry cohort was the only variable to retain an association with survival to CKRT discontinuation.

CONCLUSIONS

We suggest children receiving CKRT using CARPEDIEM have excellent survival. Our data should be interpreted with caution given the retrospective comparison across two eras more than a decade apart.

Thermal management with and without servo-controlled system in preterm infants immediately after birth: a multicentre, randomised controlled study

BACKGROUND

The thermal servo-controlled systems are routinely used in neonatal intensive care units (NICUs) to accurately manage patient temperature, but their role during the immediate postnatal phase has not been previously assessed.

OBJECTIVE

To compare two modalities of thermal management (with and without the use of a servo-controlled system) immediately after birth.

STUDY DESIGN AND SETTING

Multicentre, unblinded, randomised trial conducted 15 Italian tertiary hospitals.

PARTICIPANTS

Infants with estimated birth weight <1500 g and/or gestational age <30⁺⁶ weeks.

INTERVENTION

Thermal management with or without a thermal servo-controlled system during stabilisation in the delivery room.

PRIMARY OUTCOME

Proportion of normothermia at NICU admission (axillary temperature 36.5°C-37.5°C).

RESULTS

At NICU admission, normothermia was achieved in 89/225 neonates (39.6%) with the thermal servo-controlled system and 95/225 neonates (42.2%) without the thermal servo-controlled system (risk ratio 0.94, 95% CI 0.75 to 1.17). Thermal servo-controlled system was associated with increased mild hypothermia (36°C-36.4°C) (risk ratio 1.48, 95% CI 1.09 to 2.01).

CONCLUSIONS

In very low birthweight infants, thermal management with the servo-controlled system conferred no advantage in maintaining normothermia at NICU admission, while it was associated with increased mild hypothermia. Thermal management of preterm infants immediately after birth remains a challenge.

Longitudinal Multi-Omics Study of a Mother-Infant Dyad from Breastfeeding to Weaning: An Individualized Approach to Understand the Interactions Among Diet, Fecal Metabolome and Microbiota Composition

The development of the human gut microbiota is characterized by a dynamic sequence of events from birth to adulthood, which make the gut microbiota unique for everyone. Its composition and metabolism may play a critical role in the intestinal homeostasis and health. We propose a study on a single mother-infant dyad to follow the dynamics of an infant fecal microbiota and metabolome changes in relation to breast milk composition during the lactation period and evaluate the changes induced by introduction of complementary food during the weaning period. Nuclear Magnetic Resonance (NMR)-based metabolomics was performed on breast milk and, together with 16S RNA targeted-metagenomics analysis, also on infant stool samples of a mother-infant dyad collected over a period running from the exclusive breastfeeding diet to weaning. Breast milk samples and neonatal stool samples were collected from the 4th to the 10th month of life. Both specimens were collected from day 103 to day 175, while from day 219-268 only stool samples were examined. An exploratory and a predictive analysis were carried out by means of Common component and specific weight analysis and multi-block partial least squares discriminant analysis, respectively. Stools collected during breastfeeding and during a mixed fruit/breastfeeding diet were characterized by high levels of fucosyl-oligosaccharides and glycolysis intermediates, including succinate and formate. The transition to a semi-solid food diet was characterized by several changes in fecal parameters: increase in short-chain fatty acids (SCFAs) levels, including acetate, propionate and butyrate, dissapearance of HMOs and the shift in the community composition, mainly occurring within the Firmicutes phylum. The variations in the fecal metabolome reflected the infant's diet transition, while the composition of the microbiota followed a more complex and still unstable behavior.

Perinatal Transmission and Outcome of Neonates Born to SARS-CoV-2-Positive Mothers: The Experience of 2 Highly Endemic Italian Regions

INTRODUCTION

COVID-19 is the disease caused by the novel coronavirus SARS-CoV-2, responsible of the pandemic declared in March 2020 and still ongoing. COVID-19 affects all ages but presents less complications and fatalities in children. Neonatal infections have rarely been reported worldwide, and vertical transmission is uncertain.

METHODS

We conducted a prospective cohort study of all infants born to SARS-CoV-2-positive mothers admitted to 2 hospitals in South (Bari) and North (Varese) of Italy from April to December 2020. A molecular nasopharyngeal swab for SARS-CoV-2 using a reverse transcriptase polymerase chain reaction was made at birth for all enrolled newborns to evaluate vertical transmission of infection. We also evaluated postnatal transmission with a second nasopharyngeal swab made at 1 month of life and described maternal and neonatal clinical findings and short-term outcomes.

RESULTS

176/179 (97%) newborns were SARS-CoV-2 negative at birth and 151/156 (97%) infants were still negative at 1 month of life. All newborns were asymptomatic. Seventy percent of newborns were breastfed during hospitalization. At 1 month of life, 76% of infants were breastfed.

CONCLUSION

According to our results, vertical and perinatal infection is very rare. Breastfeeding does not increase the risk of COVID-19 and should be encouraged.

In-hospital and web-based intervention to counteract vaccine hesitancy in very preterm infants' families: a NICU experience

BACKGROUND

Vaccine hesitancy is a global problem, carrying significant health risks for extremely vulnerable population as that of preterm infants. Social media are emerging as significant tools for public health promotion. Our aim was to evaluate both the coverage and the timeliness of routine immunizations in a cohort of preterm infants (< 33 weeks of gestational age) at 24 months of age whose families have been subjected to in-hospital and web-based interventions to counteract vaccine hesitancy.

METHODS

For a period of 2 years parents of preterm infants were instructed during their follow up visits by a member of the NICU team to get correct informations about vaccines from a social network page. Vaccination rates of preterm infants were assessed at 24 months of chronological age with an electronic database and compared to both general population and historical cohort.

RESULTS

Coverage and timeliness of vaccinations at 24 months of age of 170 preterm infants were analyzed in December 2019. Gestational age and birth weight median (IQR) were, respectively, 31.0 (5.0) weeks and 1475.0 (843.8) g. Coverage rates were similar to those of the regional population (p > 0.05), while timeliness of administration was significantly delayed compared to the recommended schedule (p < 0.001). Age of administration was not correlated with either body weight and gestational age at birth (Spearman rank, p > 0.05). DTaP-IPV-HBV-Hib 2nd and 3rd doses, MMR and Varicella vaccines coverage data were higher compared to historical cohort (p < 0.05).

CONCLUSION

Increasing vaccine confidence through web-based interventions could have a positive impact on vaccination acceptance of parents of preterm infants, although timeliness results still delayed. There is a strong need to develop different and effective vaccination strategies to protect this very vulnerable population.

Maternal Carriage in Late-Onset Group B Streptococcus Disease, Italy

At the time of late-onset disease, mothers often have positive breast milk culture or group B Streptococcus bacteriuria, suggesting heavy maternal colonization.

We retrospectively investigated mother-to-infant transmission of group B Streptococcus (GBS) in 98 cases of late-onset disease reported during 2007–2018 by a network in Italy. Mothers with full assessment of vaginal/rectal carriage tested at prenatal screening and at time of late onset (ATLO) were included. Thirty-three mothers (33.7%) were never GBS colonized; 65 (66.3%) were vaginal/rectal colonized, of which 36 (36.7%) were persistently colonized. Mothers with vaginal/rectal colonization ATLO had high rates of GBS bacteriuria (33.9%) and positive breast milk culture (27.5%). GBS strains from mother–infant pairs were serotype III and possessed the surface protein antigen Rib. All but 1 strain belonged to clonal complex 17. GBS strains from 4 mother–infant pairs were indistinguishable through pulsed-field gel electrophoresis. At least two thirds of late-onset cases are transmitted from mothers, who often have vaginal/rectal carriage, positive breast milk culture, or GBS bacteriuria, which suggests heavy maternal colonization.

Lecithinized superoxide dismutase in the past and in the present: Any role in the actual pandemia of COVID-19?

The Coronavirus disease 19 (Covid-19) pandemic is devastating the public health: it is urgent to find a viable therapy to reduce the multiorgan damage of the disease. A validated therapeutic protocol is still missing. The most severe forms of the disease are related to an exaggerated inflammatory response. The pivotal role of reactive oxygen species (ROS) in the amplification of inflammation makes the antioxidants a potential therapy, but clinical trials are needed. The lecitinized superoxide dismutase (PC-SOD) could represent a possibility because of bioaviability, safety, and its modulatory effect on the innate immune response in reducing the harmful consequences of oxidative stress. In this review we summarize the evidence on lecitinized superoxide dismutase in animal and human studies, to highlight the rationale for using the PC-SOD to treat COVID-19.

Maternal Psychological Factors and Onset of Functional Gastrointestinal Disorders in Offspring: A Prospective Study

BACKGROUND/OBJECTIVES

Functional gastrointestinal disorders (FGIDs) are a heterogeneous group of conditions of unclear etiology. The biopsychosocial model approach to FGIDs posits that early-life stressors may trigger a cascade of complex interactions between genetic predisposition and risk factors eventually leading to the occurrence of FGIDs. The relationship between the psychological disposition of the mother and FGIDs occurrence is poorly understood. We conducted a study to investigate if parental psychological factors may contribute to the onset of FGIDs in offspring.

METHODS

We performed a prospective cohort study of parent-infant pairs who completed a battery of self-reported psychological questionnaires and a validated Rome III questionnaire for the diagnosis of infant and toddler FGIDs. The Edinburgh Postpartum Depression Scale (EPDS) was used to examine postpartum depression (PPD) symptoms; the Maternity Blues Questionnaire (MBQ) was applied to measure maternity blues severity; the Symptoms Checklist-Revised (SCL90-R) was used to assess the presence of relevant psychiatric symptoms; adult attachment style in mothers was assessed in a continuous way through the five dimensions of the Attachment Style Questionnaire (ASQ).

RESULTS

Out of the 360 eligible mothers, 200 were enrolled, 113 completed the 3-month follow-up and were included in the final analysis. PPD symptoms prevalence was 20.4%, 20%, 13.2%, and 13.1% respectively at 3 days, 1 week, 1 month, and 3 months after delivery. 40.4% of mothers suffered from severe blues according to the MBQ. Relevant psychiatric symptoms (SCL90-R) were present in 7.8% and 10.9% of mothers, respectively at 1 week and 3 months after delivery. 48.7% of mothers showed a secure attachment pattern measured through the RQ. At 1-month follow-up, infant regurgitation was diagnosed in 26 (23%) of infants, infantile colic in 31 (27.4%), dyschezia in 17 (15%), and functional constipation in 9 (8%). At 3-month follow-up, FGIDs prevalence was respectively 16 (19.3%), 11 (13.3%), 4 (4.8%), and 11 (13.3%). A significant positive association between PPD symptoms starting 3 days after delivery and the presence of infantile colic on setting 1 month after birth was found (P = 0.028), as well as between PPD symptoms occurrence 7 days after delivery and infantile regurgitation beginning 1 month after birth (P = 0.042). A higher prevalence of infantile colic was found in the offspring of mothers suffering from PPD symptoms from 3 days after delivery (54.5 vs 19.8; P = 0.001). No significant association was found between FGIDs and psychiatric symptoms and maternity blues at any timepoint. On the other hand, mothers of infants with regurgitation with an onset 1 month after birth have higher insecurity score in avoidant and fearful ASQ-related attachment dimensions (respectively, P = 0.03, P = 0.042, P = 0.03).

CONCLUSIONS

Maternal psychological factors might contribute to the onset of infant FGIDs in offspring. Early screening of postpartum depression symptoms and early implementation of psychological interventions within the postpartum period might promote the health of the mother-infant dyad.

Infantile Functional Gastrointestinal Disorders and Maternal Psychological Status: A Narrative Review

BACKGROUND

Functional gastrointestinal disorders are often extremely distressing for the infant and parents, leading to infant discomfort and crying, parental anxiety, repeated healthcare consultations, and escalating healthcare costs.

AIM

In this narrative review, we analyzed the relationship between maternal psychological status during pregnancy and postpartum and the main infantile functional gastrointestinal disorders.

MATERIALS AND METHODS

The narrative review was conducted searching scientific databases for articles reporting on infantile functional gastrointestinal disorders in association with maternal depressive or anxiety disorders.

RESULTS

Seven studies were suitable.

DISCUSSION

Maternal psychological disorders may be correlated to infantile functional gastrointestinal disorders. Whether it is the excessive crying that favors the onset of maternal psychological disorders or, in contrast, an altered attachment style due to the maternal status that facilitates the onset of functional gastrointestinal disorders in the infant is still an open question. Recent findings revealed that both anxious and depressed mothers are more likely to have an adverse gut microbiome.

CONCLUSION

A healthy interaction of the mother-baby dyad is advantageous in ensuring the mental and physical development of the offspring. Gynecologists, general practitioners and pediatricians should be alert for early identification of mothers at risk with the aim to initiate timely targeted interventions. Further research on the role of microbiota and the possible therapeutic approaches with probiotics is required.

The First Case of Congenital Myasthenic Syndrome Caused by a Large Homozygous Deletion in the C-Terminal Region of COLQ (Collagen Like Tail Subunit of Asymmetric Acetylcholinesterase) Protein

Congenital myasthenic syndromes (CMSs) are caused by mutations in genes that encode proteins involved in the organization, maintenance, function, or modification of the neuromuscular junction. Among these, the collagenic tail of endplate acetylcholinesterase protein (COLQ; MIM 603033) has a crucial role in anchoring the enzyme into the synaptic basal lamina. Here, we report on the first case of a patient with a homozygous deletion affecting the last exons of the COLQ gene in a CMS patient born to consanguineous parents of Pakistani origin. Electromyography (EMG), electroencephalography (EEG), clinical exome sequencing (CES), and single nucleotide polymorphism (SNP) array analyses were performed. The subject was born at term after an uneventful pregnancy and developed significant hypotonia and dystonia, clinical pseudoseizures, and recurring respiratory insufficiency with a need for mechanical ventilation. CES analysis of the patient revealed a homozygous deletion of the COLQ gene located on the 3p25.1 chromosome region. The SNP-array confirmed the presence of deletion that extended from exon 11 to the last exon 17 with a size of 19.5 Kb. Our results add new insights about the underlying pathogenetic mechanisms expanding the spectrum of causative COLQ mutations. It is relevant, considering the therapeutic implications, to apply suitable molecular approaches so that no type of mutation is missed: “each lost mutation means a baby treated improperly”.

Premature Birth is an Independent Risk Factor for Early Adiposity Rebound: Longitudinal Analysis of BMI Data from Birth to 7 Years

Adiposity rebound (AR) refers to the second rise of the body mass index (BMI) curve that usually occurs physiologically between five and seven years of age. AR timing has a great impact on patients’ health, since early adiposity rebound (EAR) is associated with the development of metabolic syndrome later in life. We aimed to investigate the prevalence of EAR in a cohort of inborn preterm infants admitted to the Neonatal Intensive Care Section of the Policlinico University Hospital of Bari, Italy. Secondarily, we assessed whether some determinants such as (1) gender; (2) delivery mode; (3) birth weight and classification into small, normal, or large for gestational age; (4) type of feeding; (5) breastfeeding duration; (6) timing of introduction of solid food; (7) parental education; and (8) parental pre-pregnancy body mass index (BMI) influenced EAR in this cohort. The tertiary aim was to evaluate the prevalence of obesity or being overweight at seven years of age in children according to early versus timely AR. This is a prospective, population-based longitudinal study conducted at the Neonatal Intensive Care Section of the Policlinico University Hospital of Bari, Italy. Inborn preterm infants admitted to the neonatal ward between 2009 and 2011 were eligible. Enrolled preterm infants were evaluated at birth and at 1, 3, 6, 9, 12, 15, 18, and 24 months and 3, 4, 5, 6, and 7 years of age. Weight and height data were analyzed, and BMI was calculated. AR was assessed in the growth trajectory in a body mass index (BMI) plot. Of the 250 preterm newborns included, 100 completed the seven-year follow-up and entered the final analysis, 138 were lost during the seven-year follow-up, and in 12 cases parents withdrew over the course of the study. The prevalence of EAR in our cohort of preterm newborns was 54% at seven years of age. Early adiposity rebound was associated with being large for gestational age (LGA) at birth. No other factors were associated with EAR. Early adiposity rebounders had a significantly higher BMI at seven years compared to children with timely AR (17.2 ± 2.7 vs. 15.6 ± 2.05, p = 0.021). No significant differences were found in the prevalence of obesity or being overweight at seven years of age in children with early or timely AR (29% vs. 14%, p = 0.202). Ex-preterm infants have an increased risk of EAR. Since EAR may lead to long-term detrimental health effects with the onset of various chronic diseases (e.g., obesity, metabolic syndrome, etc.), healthcare providers should be prepared to counteract its occurrence, especially in delicate sub-populations of infants.

Systematic review found that using thin catheters to deliver surfactant to preterm neonates was associated with reduced bronchopulmonary dysplasia and mechanical ventilation

AIM

Surfactant delivery is a cornerstone for managing respiratory distress in preterm neonates, but data on the best surfactant delivery methods have been conflicting.

METHODS

A systematic literature review using the PubMed, Embase, Cochrane Library and Web of Science databases identified papers published up to November 5, 2019. Additional studies were identified from trial registries, conference proceedings and the reference lists of the selected papers.

RESULTS

We identified 15 studies covering 4926 preterm infants. The randomised controlled trials (RCTs) and observational studies both showed significant reductions in early intubation rates with use of thin catheters. The relative risk (RR) was 0.63 and the 95% confidence interval (95% CI) was 0.55-0.72 (P < .01), with an odds ratio (OR) of 0.40 and 95% CI of 0.35-0.45 (P < .0001). The collective results from the RCTs revealed a significant decrease in bronchopulmonary dysplasia (BPD) rates in the thin catheter group (RR, 0.47; 95% CI 0.33-0.66; P < .01). These findings were consistent with the observational studies (OR 0.47; 95% CI 0.43-0.52; P < .01).

CONCLUSION

Using thin catheters to deliver surfactant in comparison with intubate-surfactant-extubate (INSURE) to newborn preterm infants with respiratory distress was associated with a reduced incidence of BPD and less need for mechanical ventilation.

Effect of Limosilactobacillus reuteri LRE02-Lacticaseibacillus rhamnosus LR04 Combination on Antibiotic-Associated Diarrhea in a Pediatric Population: A National Survey

Probiotics are living microorganisms, which, upon oral ingestion, may prevent antibiotic-associated diarrhea (AAD) through the normalization of an unbalanced gastrointestinal flora. The objective of this study was to evaluate the benefits of a probiotic combination (Limosilactibacillus reuteri LRE02-DSM 23878 and Lacticaseibacillus rhamnosus LR04-DSM 16605) on the prevention of AAD in an outpatient pediatric setting. Questionnaires were delivered to pediatricians by each patient/parent during the visits after antibiotics and probiotics treatment to monitor physiological parameters. The primary outcome of both groups (probiotics and no probiotics treated) was the evaluation of the prevalence of AAD between the two groups. Evaluation of stool consistency using the Bristol Stool Scale (BSS) score was performed, as well as the evaluation of AAD duration, frequencies of daily evacuation, and the beginning of diarrhea and weight loss during AAD in both groups and related to antibiotic categories. Results indicated that probiotics, at the recommended dosage of 1.2 × 10⁹ CFU (Colony Forming Unit) per day for 30 days, are associated with lower rates of AAD and a decreased number of days with diarrhea, independent of the type of antibiotic used. Moreover, the use of probiotics resulted in a normal stool consistency in a shorter time period, as evaluated by the BSS.

Continuous kidney replacement therapy in critically ill neonates and infants: a retrospective analysis of clinical results with a dedicated device

BACKGROUND

Providing extracorporeal renal support to neonates and infants involves a number of technical and clinical issues, possibly discouraging early utilization. This report aims to describe a multicenter experience of continuous kidney replacement therapy (CKRT) delivery to small infants using a device specifically designed for this age group.

METHODS

A retrospective cohort analysis of all patients treated with the Carpediem™ machine (Bellco-Medtronic, Mirandola, Italy) in 6 centers between June 2013 and December 2016.

RESULTS

Twenty-six neonates and small infants received 165 CKRT sessions in convective modality. Median age at neonatal intensive care unit admission 1 day (IQR 1-11), median body weight 2.9 kg (IQR 2.2-3.6). Median circuit duration 14 h (IQR 10-22), with delivered/prescribed time ratio of 84%. CKRT was conducted using 4 Fr (27%), 5 Fr (35%), 6.5 Fr (11%), and 7 Fr (3%) vascular access, and with umbilical and peripheral accesses (11% each) allowing overall median blood flow of 4.5 ml/kg/min (IQR 3.4-6) and median effluent flow rate 35 ml/kg/h (IQR 28-42). Circuits were primed with normal saline in 58% of treatments, colloids in 31%, and packed red blood cells in 11%. No serious adverse events directly related to machine application were reported by any center. Twenty-five (96%) patients survived their CKRT course and 13 patients (50%) survived to ICU discharge.

CONCLUSIONS

CKRT in neonates was easy to initiate and conduct when performed with small central vascular accesses coupled with this device. A dedicated technology for infant CKRT delivery enables patients to be safely treated avoiding technical complications. Graphical abstract.

Birth Weight and the Development of Functional Gastrointestinal Disorders in Infants

PURPOSE

To assess the association between birth weight and the development of functional gastrointestinal disorders (FGIDs) in the first year of life.

METHODS

This is a secondary analysis of a prospective cohort multicenter study including neonates, consecutively enrolled at birth, and followed up for one year. At birth all infants were classified by birth weight as extremely low (ELBW), very low, or low when <1,000, <1,500, and <2,500 g, respectively, and by birth weight for gestational age as appropriate (AGA, weight in the 10-90th percentile), small (SGA, weight <10th percentile), and large (LGA, weight >90th percentile) for gestational age. FGIDs were classified according to the Rome III criteria and assessed at 1, 3, 6, and 12 months of life.

RESULTS

Among 1,152 newborns enrolled, 934 (81.1%) completed the study: 302 (32.3%) were preterm, 35 (3.7%) were ELBW, 104 (11.1%) were SGA, 782 (83.7%) were AGA, and 48 (5.1%) were LGA infants. Overall, throughout the first year of life, 718 (76.9%) reported at least one FGID. The proportion of infants presenting with at least one FGID was significantly higher in ELBW (97%) compared to LBW (74%) (p=0.01) and in LGA (85.4%) and SGA (85.6%) compared to AGA (75.2%) (p=0.0001). On multivariate analysis, SGA was significantly associated with infantile colic.

CONCLUSION

We observed an increased risk of FGIDs in ELBW, SGA, and LGA neonates. Our results suggest that prenatal factors determining birth weight may influence the development of FGIDs in infants. Understanding the role of all potential risk factors may provide new insights and targeted approaches for FGIDs.

Analysis of relation between placental lesions and perinatal outcome according to Amsterdam criteria: a comparative study

BACKGROUND

To verify the correlation between histological examination of the placenta (HP), classifying the lesions according to the Amsterdam criteria (AC), and the main neonatal pathological patterns.

METHODS

This prospective study carried out at the University of Bari between May 2015 and May 2017,enrolled 350 pregnant women. Complete obstetric history and HP was collected. 380 newborns were also enrolled. The analysis was also carried out by comparing the incidence of the various placental pathologies in the sample of physiological pregnancies (PP), represented by 142 cases, with the incidence of the group with placental anomalies (PA). The statistical software used was STATA MP11.

RESULTS

Respiratory disorders (61 cases) are significantly correlated with generic PA (p=0.006). Neonatal sepsis (15 cases) was significantly correlated with placental inflammation (p=0.035) and villitis of unknown origin (p=0.039).Twin pregnancies (50 cases) were correlated with generic PA (p=0.00001) and late maternal malperfusion (p=0.00001). Congenital cardiopathies (50 cases) were correlated with the villitis of unknown origin and PA (p=0.0000). Preterm birth (145 cases)was correlated with the premature malperfusion (p=0, 0011) and PA (p=0.0000); SGA (low weight in relation to the gestational age - 75 cases) neonates were correlated with the early malperfusion (p=0.00000) and the generic PA (p=0.00000).

CONCLUSIONS

The present study has therefore verified whether in reality the HP can be of great help to the neonatologist in the nosological and therapeutic setting of the pathological newborn. The pathological examination of the placenta is nevertheless essential to clarify the causes of the stillbirths and that these causes are particularly important for the obstetric and neonatal outcome of subsequent pregnancies.

The recurrent SETBP1 c.2608G > A, p.(Gly870Ser) variant in a patient with Schinzel-Giedion syndrome: an illustrative case of the utility of whole exome sequencing in a critically ill neonate

Background

Schinzel-Giedion syndrome (SGS) is a multiple malformation syndrome mainly characterized by severe intellectual disability, distinctive facial features, and multiple congenital anomalies, including skeletal abnormalities, genitourinary and renal malformations, cardiac defects, as well as an increased pediatric cancer risk. Recently, SGS has been associated with de novo heterozygous deleterious variants in the SETBP1 gene; to date, nine different variants, clustering in exon 4 of SETBP1, have been identified in 25 patients.

Case presentation

In this study, by using Whole Exome Sequencing (WES), we identified a patient with a recurrent missense mutation in SETBP1, the c.2608G > A, p.(Gly870Ser) variant, previously reported as likely pathogenic. This finding allowed us to confirm the suspected clinical diagnosis of SGS. Clinical features of patients carrying the same variant, including our patient, were evaluated by a review of medical records.

Conclusions

Our study confirms SGS as a severe disorder potentially presenting at birth as a critically ill neonate and demonstrates the causal role of the c.2608G > A, p.(Gly870Ser) variant in the etiology of the syndrome. Moreover, although the cohort of SETBP1-patients reported in the literature is still small, our study reports for the first time the prevalence of the variant (about 27%, 7/26). Finally, given the heterogeneity of clinical presentations of affected patients hospitalized in Neonatal Intensive Care Units (NICU) and/or Pediatric Intensive Care Units (PICU), in agreement with emerging data from the literature, we suggest that WES should be used in the diagnosis of unexplained syndromic conditions, and even as part of a standard first-line diagnostic approach, as it would allow a better diagnosis, counseling and management of affected patients and their families.

Resveratrol plus carboxymethyl-β-glucan in infants with common cold: A randomized double-blind trial

Objectives

To evaluate effectiveness of a nasal resveratrol/carboxymethyl-β-glucan solution compared to nasal saline solution: a) on common cold symptoms by means of a validated measure scale (CARIFS score), b) on Rhinovirus infection and CCL2, CCL5, IL8, IL6, CXCL10 and TLR2 expression in nasal swabs, c) on frequency of relapses after 30 days of follow-up.

Methods

89 infants with respiratory infection symptoms were randomly assigned to receive either a nasal resveratrol/carboxymethyl-β-glucan solution or nasal saline solution.

All patients were evaluated with CARIFS score at enrollment, after 48 h, 7 and 30 days by physicians and parents. Nasal swabs were obtained at enrollment, after 48 h and after one week.

Results

CARIFS score improved in both groups. Episodes of sneezing and cough were fewer in study group after 7 days of follow-up (p < 0.05). No significant differences were found on nasopharyngeal swabs in Rhinovirus detection and cytokines expression after 48 h, nor in 30 days relapses. TLR2 expression was significantly higher in Rhinovirus infected children of the study group. No adverse effects occurred.

Conclusions

These data suggest that a solution containing resveratrol plus carboxymethyl-β-glucan might have a positive impact on both clinical and socio-economic burden due to infant common cold.

Hydrolyzed Protein Formula for Allergy Prevention in Preterm Infants: Follow-Up Analysis of a Randomized, Triple-Blind, Placebo-Controlled Study

Background: Allergic diseases are a major public health burden worldwide. Evidence suggests that early nutrition might play a key role in the future development of allergies and the use of hydrolyzed protein formulas have been proposed to prevent allergic disease, mainly in term infants with risk factors. Aim: To evaluate the preventive effect of a hydrolyzed protein formula vs. an intact protein formula on allergy development in preterm infants with or without risk factors. Methods: We performed a 3-year follow-up study of a previous triple-blind, placebo-controlled randomized trial. Evidence of atopic dermatitis, asthma and IgE-mediated food allergies were evaluated according to a validated parental questionnaire (Comprehensive Early Childhood Allergy Questionnaire). Food sensitization was also investigated by skin prick test at 3 years of chronological age. Results: Of the 30 subjects in the intact protein formula group and 30 in the extensively hydrolyzed formula group, respectively 18 and 16 completed the 3-year follow-up and entered the final analysis. No group differences in the incidence of atopic dermatitis, asthma, IgE-mediated food allergies, and food sensitization were found. Conclusion: Despite the small number of cases, extensively hydrolyzed protein formula seems to be ineffective in allergic diseases prevention in preterm neonates. Further adequately powered, randomized controlled trials evaluating hydrolyzed protein formula administration to prevent allergic diseases in preterm neonates are needed.

Magnesium Alginate in Gastro-Esophageal Reflux: A Randomized Multicenter Cross-Over Study in Infants

The aims of this study were to evaluate the efficacy of magnesium alginate in decreasing functional regurgitation symptoms in infants, and to assess the cost-benefit ratio of magnesium alginate compared to a thickened formula. A multicenter perspective cross-over study was conducted in formula-fed infants with persisting regurgitation, randomly assigned to receive two weeks of a magnesium-alginate-based formulation followed by two weeks of thickened formula, or vice-versa. Infants, exclusively breast-fed, were followed up for two weeks while receiving magnesium alginate. Symptoms of gastroesophageal reflux (GER) were evaluated through the Infant Gastroesophageal Reflux Questionnaire Revised (I-GERQ-R). Direct cost of treatments was also calculated. Seventy-two infants completed the study. We found a significant reduction of I-GERQ-R scores over time (F = 55.387; p < 0.001) in all groups with no difference between the sequences of administration (F = 0.268; p = 0.848) in formula-fed infants and between exclusively breast-fed and formula-fed infants receiving magnesium alginate (t = 1.55; p = 0.126). The mean cost savings per infant was € 4.60 (±11.2) in formula-fed infants treated with magnesium alginate compared to thickened formula (t = 2.91, p < 0.0005). Conclusions were that the magnesium-alginate formulation reduces GER symptoms both in formula-fed and breast-fed infants. In formula-fed infants, clinical efficacy is similar to thickened formulas with a slightly lower cost of treatment.
