The composition and function of human milk is unique and gives a basis for the development of modern artificial milk formulas that can provide an appropriate substitute for non-breastfed infants. ...Although human milk is not fully substitutable, modern milk formulas are attempting to mimic human milk and partially substitute its complex biological positive effects on infants. Besides the immunomodulatory factors from human milk, research has been focused on the composition and structure of human milk fat with a high content of β-palmitic acid (sn-2 palmitic acid, β-palmitate). According to the available studies, increasing the content of β-palmitate added to milk formulas promotes several beneficial physiological functions. β-palmitate positively influences fatty acid metabolism, increases calcium absorption, improves bone matrix quality and the stool consistency, and has a positive effect on the development of the intestinal microbiome.

Abstract
Objective: Bronchial asthma is characterised by chronic airway inflammation commonly associated with increased oxidative stress. Exhaled carbon monoxide (eCO) levels could act as markers of ...both oxidative stress and allergic inflammation. We aimed to study eCO levels in asthmatics and detect the possible factors influencing them. Methods: We studied 241 asthmatic children and 75 healthy children. The differences in eCO levels among various asthmatic phenotypes and the correlations between eCO and other measured parameters (spirometric indices, Asthma Control Test score, exhaled nitric oxide, total IgE, blood eosinophils and marker of oxidative damage of proteins) were analysed. Results: Levels of eCO widely differed according to the selected characteristics of asthma. Asthmatics showed higher eCO concentrations than controls (1.44 ± 0.12 ppm vs. 0.91 ± 0.11 ppm, p < 0.001). Acute exacerbation of asthma was accompanied by a significant increase in eCO compared to the clinically controlled stage (2.17 ± 0.36 ppm vs. 1.33 ± 0.13 ppm, p < 0.001). Atopic, non-atopic asthma and asthma associated with allergic rhinitis (AR) showed elevated levels of eCO. The levels of eCO negatively correlated with the marker of protein oxidation in asthmatics, especially in atopic form and during acute exacerbation. Conclusions: In a population of asthmatic children, eCO levels could be considered as a marker of both allergic inflammation and oxidative stress in the airways. Concomitant AR and asthma control were the most important factors affecting the levels of eCO in asthmatic children. However, our results do not support the use of routine eCO in the clinical practice.
The study assessed the presence of sleep abnormalities in children who had recently been diagnosed with celiac disease (CD) and not started a gluten free diet (GFD). The children's polysomnographic ...profiles were also characterized and further compared with healthy children of the same age.
This prospective cross-sectional study involved 46 pediatric subjects (aged 1-19 years) who had recently been diagnosed with CD and not started a GFD. The control group consisted of 32 healthy children (aged 2-17 years). All children underwent anthropometric measurement, laboratory testing and standard overnight observation with in-laboratory video-PSG. The study and control group were divided into subgroups according to the subjects' median ages (8.1 years): celiac children aged less than 8.1 years (n = 23) and more than 8.1 years (n = 23), healthy children less aged than 8.1 years (n = 16) and more than 8.1 years (n = 16).
No significant differences in the basic demographic and anthropometric parameters between the celiac and control group were observed. Significantly prolonged sleep latency (SOL) was evident in the celiac subjects (21.89 ± 20.77 min. vs. 10.99 ± 7.94 min, p = 0.02), with a probability of prolonged SOL of 4.23-fold greater (OR = 4.23; 95 % CI 1.1-16.22) than the healthy controls, especially in the subgroup of older celiac patients. No significant differences in the sleep period time (SPT), total sleep time (TST), wake during sleep (WASO), sleep efficiency (SE) and sleep stage distribution and cyclization were found. The respiratory rates during sleep indicated a significantly greater incidence of the central apnea-hypopnea index (CAHI) (0.54 ± 0.78 vs. 0.18 ± 0.24, p = 0.03) with a 3.16-fold greater probability of pathological CAHI (OR = 3.16; 95 % CI 1.02-9.77) than the control group. An increased incidence of CSA in the subgroup of younger celiac patients compared to younger healthy controls was especially evident.
The findings of our study suggest a difference in sleep architecture and an increased incidence of CSA in children with untreated CD, but additional research is required to verify the results.

We present the first real-world-data study on teduglutide-treated SBS patients in the Slovak Republic and the first study to enable the comparison of the effects of teduglutide treatment between ...the adult and pediatric populations. (2)
This was a non-interventional retrospective cohort study of adult and pediatric SBS patients treated with teduglutide. Primary and secondary endpoints were the results of teduglutide use at 12 weeks and 6 months after the initiation of treatment, compared to baseline. (3)
Teduglutide treatment led to a statistically significant reduction in the volume of intravenous hydration, HPN caloric intake, HPN and intravenous hydration applications per week and to increased urine output in adult patients. The results in the pediatric population were similar, but not statistically significant. A complete weaning off HPN was achieved in 57.14% of all patients (50.00% of children; 62.50% of adults) after a median of 0.99 years of teduglutide treatment (1.07 and 0.98 years for children and adults, respectively). (4)
Teduglutide treatment in SBS patients leads to considerable reduction in or even weaning off PN in both pediatric and adult patients.
Nephronophthisis, an autosomal recessive cystic kidney disease, represents genetically heterogenous group of diseases that lead to end-stage kidney disease in children and young adults. The typical ...clinical manifestations are polyuria, enuresis and growth failure. Left ventricular non-compaction cardiomyopathy is a rare form of cardiomyopathy, is determined by the disturbance of embryogenesis of the endocardium and myocardium. Primary ciliary dyskinesia is a genetically heterogeneous recessive disorder of motile cilia characterised by chronic lung disease and nonpulmonary manifestations, usually situs inversus. Almost no information is available in the literature about the association between nephronophthisis, left ventricular non-compaction cardiomyopathy and reduced cilia motility. The authors present the case of 17 year-old girl with left ventricular non-compaction cardiomyopathy, non-specific lung nodules and end-stage kidney disease. A genetic examination confirmed only diagnosis of nephronophthisis type I. Cardiac magnetic resonance imaging confirmed left ventricular non-compaction cardiomyopathy. Cilia motility was reduced in nasal mucosa samples. Are all clinical manifestations part of one disease? This report points to a variety of clinical manifestations of ciliopathy and aims to understand the individual relationships.
In contrast to adult-onset inflammatory bowel disease (IBD), where many genetic loci have been shown to be involved in complex disease etiology, early-onset IBD (eoIBD) and associated syndromes can ...sometimes present as monogenic conditions. As a result, the clinical phenotype and ideal disease management in these patients often differ from those in adult-onset IBD. However, due to high costs and the complexity of data analysis, high-throughput screening for genetic causes has not yet become a standard part of the diagnostic work-up of eoIBD patients.
We selected 28 genes of interest associated with monogenic IBD and performed targeted panel sequencing in 71 patients diagnosed with eoIBD or early-onset chronic diarrhea to detect causative variants. We compared these results to whole-exome sequencing (WES) data available for 25 of these patients.
Target coverage was significantly higher in the targeted gene panel approach compared with WES, whereas the cost of the panel was considerably lower (approximately 25% of WES). Disease-causing variants affecting protein function were identified in 5 patients (7%), located in genes of the IL10 signaling pathway (3), WAS (1), and DKC1 (1). The functional effects of 8 candidate variants in 5 additional patients (7%) are under further investigation. WES did not identify additional causative mutations in 25 patients.
Targeted gene panel sequencing is a fast and effective screening method for monogenic causes of eoIBD that should be routinely established in national referral centers.
Primary immunodeficiencies (PID) are becoming a recognized public health problem worldwide. The most important subgroup of these disorders are the antibody deficiencies. X-linked agammaglobulinaemia ...was the first described entity of this group and is characterised by early onset of recurrent bacterial infections, profound deficiency of all immunoglobulin isotypes and markedly reduced number of peripheral B-lymphocytes.
We report the case of a 10-year old boy with X-linked agammaglobulinaemia caused by a previously non-described mutation in BTK gene with typical clinical presentation but delayed diagnosis. Following diagnosis, substitution therapy with intravenous immunoglobulins was started and the clinical status of the patient improved.
We reported a case of X-linked agammaglobulinaemia with delayed diagnosis despite the typical anamnestic signs for primary humoral immunodeficiency. The disease was caused by a previously non-reported mutation in the BTK gene. Measurement of serum immunoglobulins should be performed in all children with recurrent, complicated respiratory infections as a screening test for humoral immunodeficiencies.
Abstract Mitchell-Riley syndrome, an autosomal recessive disorder caused by mutations in the RFX6 gene, is defined as a combination of neonatal diabetes mellitus and serious congenital ...gastrointestinal defects. We describe Mitchell-Riley syndrome in two sisters with two novel compound heterozygous variants in the RFX6 gene: c.1154G > A, p.(Arg385Gln), and c.1316_1319delTCTA, p.(Ile439Thrfs*13). Both sisters present milder forms of the syndrome, likely due to possible residual activity of the p.Arg385Gln variant, which is localized in a dimerization domain of the RFX6 transcription factor. We propose that the prognosis is dependent on patient RFX6 genotype and possible residual activity of RFX6 transcription factor. Both sisters had atypical later onset of diabetes, at 2 years and 10 months and 2 years and 7 months, respectively. This supports the need of extending the definition of diabetes in Mitchell-Riley syndrome from neonatal to childhood onset and regular glyceamia check in patients with gastrointestinal tract malformations typical for Mitchell-Riley syndrome. The clinical course in both sisters improved significantly after surgical removal of parts of the small intestine with heterotopic gastric mucosa. We suggest that gastric mucosa heterotopy is an important actionable part of Mitchell-Riley syndrome and could have been responsible for the malabsorption, failure to thrive and severe anemia present in previously reported patients with Mitchell-Riley syndrome.

Besides the typical symptoms of allergic reaction after wasp sting, unusual and unexpected reactions may also develop. In this report, a case of severe peripheral quadriparesis and sphincteric ...disorder (urinary incontinence) in a 10-year-old boy occurring within 24 hours after wasp sting is presented. Corticosteroids had very good therapeutic effect, and improvement in clinical status was observed within 72 hours. The exact pathogenic mechanism of peripheral nervous system damage is not very well known. Several studies have suggested that besides the neurotoxic effect of wasp venom, delayed immunological response to wasp antigens followed by an allergy-triggered autoimmune reaction is possible. Wasp venom may activate an allergic reaction or effects by toxic impacts; however, typical clinical symptoms of allergic reaction are not necessarily present.
