Associations between infants' crying, sleep and cortisol secretion and mother's sleep and well-being.

BACKGROUND: Infants' continuous crying is a challenge both for the child and the principal caregiver. However, the links between infants' sleep, crying and cortisol secretion and mothers' well-being and sleep have been scarcely investigated. The aim of the present study was therefore to examine the link between cortisol secretion, crying and sleep of infants characterized by infantile colic (IC) and mothers' psychological well-being and own sleep. METHODS: Mothers of 24 infants characterized by IC (mean age = 8 weeks, SD = 1.5 weeks) completed a series of questionnaires regarding the infant's crying and sleeping patterns. Infants' sleep was objectively assessed with actigraphs. Cortisol secretion was measured by means of saliva samples in the mornings after waking. After 4 weeks, infants were assessed once again. Mothers completed questionnaires assessing their psychological well-being (depressive symptoms, family strain) and sleep. RESULTS: Mothers' psychological well-being and sleep was greatly predicted by infants' morning saliva cortisol levels, sleep disruptions and crying intensity, whereas infants' crying duration and volume had low predictive value. CONCLUSIONS: Mothers with infants characterized by IC are at increased risk for reporting impaired sleep, developing depressive symptoms and reporting higher family strain. Most importantly, this risk seems to be greater if their infants' sleep is fragmented.

The effect of the COVID-19 pandemic on pediatric emergency department utilization in three regions in Switzerland.

PURPOSE: The COVID-19 pandemic was associated with a decrease in emergency department (ED) visits. However, contradictory, and sparse data regarding children could not yet answer the question, how pediatric ED utilization evolved throughout the pandemic. Our objectives were to investigate the impact of the pandemic in three language regions of Switzerland by analyzing trends over time, describe regional differences, and address implications for future healthcare. METHODS: We conducted a retrospective, longitudinal cohort study at three Swiss tertiary pediatric EDs (March 1st, 2018-February 28th, 2022), analyzing the numbers of ED visits (including patients` age, triage categories, and urgent vs. non-urgent cases). The impact of COVID-19 related non-pharmaceutical interventions (NPIs) on pediatric ED utilization was assessed by interrupted time series (ITS) modelling. RESULTS: Based on 304'438 ED visits, we found a drop of nearly 50% at the onset of NPIs, followed by a gradual recovery. This primarily affected children 0-4 years, and both non-urgent and urgent cases. However, the decline in urgent visits appeared to be more pronounced in two centers compared to a third, where also hospitalization rates did not decrease significantly during the pandemic. A subgroup analysis showed a significant decrease in respiratory and gastrointestinal diseases, and an increase in the proportion of trauma patients during the pandemic. CONCLUSIONS: The COVID-19 pandemic had substantial effects on number and reasons for pediatric ED visits, particularly among children 0-4 years. Despite equal regulatory conditions, the utilization dynamics varied markedly between the three regions, highlighting the multifactorial modification of pediatric ED utilization during the pandemic. Furthermore, future policy decisions should take regional differences into account.

[Failure to thrive in childhood]. / Soll das Essen Dir gedeih'n, musst Du heiter dabei sein - Gedeihstörung beim Kind.

Failure to thrive is a state of malnutrition in a child due to inadequate caloric intake, inadequate caloric absorption, or excessive caloric expenditure. This all can lead to underweight and retarded growing, but also to a possible impairment of the immune system, as well as an impairment of the psychomotoric and cognitive development of a child. The aim of this article is to offer sound knowledge to the practising physician about definition, prevalence, etiology, diagnostic evaluation and therapy of failure to thrive.

'Oh, baby, please don't cry!': in infants suffering from infantile colic hypothalamic-pituitary-adrenocortical axis activity is related to poor sleep and increased crying intensity.

BACKGROUND/AIM: Infantile colic (IC) is considered to represent the upper end of the spectrum of early developmental crying behavior. Little is known about hypothalamic-pituitary-adrenocortical axis activity and sleep in relation to infants' crying. The aim of the present study was to assess cortisol secretion in infants in relation to their sleep and crying patterns. METHOD: Sixteen infants (mean age: 8 weeks; SD = 1.5 weeks) were enrolled. Their mothers completed a series of questionnaires regarding the infants' crying and sleeping patterns. The infants' sleep was objectively assessed with actigraphs. After 4 weeks, the infants were assessed once again. Cortisol secretion was measured by means of saliva samples in the mornings after awakening. RESULTS: Morning saliva cortisol levels were related to more frequent awakening and to increased crying intensity, but not to sleep or crying duration. Over 4 weeks, both crying behavior and sleep duration decreased, but there was no association between them. Cortisol secretion did not significantly change. CONCLUSIONS: In infants suffering from IC, fragmented sleep patterns and increased saliva cortisol levels were related. Cortisol secretion seems to be related to crying intensity, but not to crying duration. Crying intensity may reflect greater physiological or psychological stress rather than mere duration of crying.

Fecal S100A12 and fecal calprotectin as noninvasive markers for inflammatory bowel disease in children.

BACKGROUND: Fecal calprotectin is a sensitive marker for gut inflammation. Recently, we have established that a related protein, S100A12, is elevated in the feces of children with inflammatory bowel disease (IBD). This may represent a specific and sensitive disease marker. The objective was to investigate the utility of fecal S100A12, in comparison to fecal calprotectin and standard inflammatory markers, as a screening marker for IBD in children with gastrointestinal symptoms. METHODS: Stool samples were obtained from 61 children presenting with gastrointestinal symptoms requiring endoscopy. Fecal S100A12, calprotectin, and serum S100A12 levels were measured and correlated to final diagnosis and standard tests (ESR, CRP, platelet count, and albumin). RESULTS: Children diagnosed with IBD (n = 31) had elevated fecal S100A12 (median 55.2 mg/kg) and calprotectin (median 1265 mg/kg) levels compared with the children without IBD (n = 30; S100A12: median 1.1 mg/kg, P < 0.0001; calprotectin: median 30.5 mg/kg; P < 0.0001). The sensitivity and specificity of fecal S100A12 (cutoff 10 mg/kg) for the detection of IBD were both 97%, whereas fecal calprotectin (cutoff 50 mg/kg) gave a sensitivity of 100% and a specificity of 67%. CONCLUSIONS: Both fecal markers were superior to the sensitivities and specificities of any standard inflammatory test. Both fecal S100A12 and calprotectin are sensitive markers of gastrointestinal inflammation, but fecal S100A12 provided exceptional specificity in distinguishing children with IBD from children without IBD. Fecal S100A12 is a simple, noninvasive test that can be used to screen and select children warranting further invasive and laborious procedures such as endoscopy for the investigation of their gastrointestinal symptoms.

The push-pull T technique: an easy and safe procedure in children with the buried bumper syndrome.

Percutaneous endoscopic gastrostomy (PEG) tube placement is a well-established procedure in adults as well as in pediatric patients who cannot be orally fed. However, potential serious complications may occur. The buried bumper syndrome is a well-recognized long-term complication of PEG. Overgrowth of gastric mucosa over the inner bumper of the tube will cause mechanical failure of formula delivery, rendering the tube useless. However, published experience in children with buried bumper syndrome is very scarce. In the authors' clinic, 76 PEG tubes were placed from 2001 to 2008, and buried bumper syndrome occurred in 1 patient. The authors report on their experience with buried bumper syndrome, an adapted safe endoscopic removal technique, as well as recommendations for prevention of buried bumper syndrome.

Antiendomysial and antihuman recombinant tissue transglutaminase antibodies in the diagnosis of coeliac disease: a biopsy-proven European multicentre study.

OBJECTIVE: To investigate the value of serum antitissue transglutaminase IgA antibodies (IgA-TTG) and IgA antiendomysial antibodies (IgA-EMA) in the diagnosis of coeliac disease in cohorts from different geographical areas in Europe. The setting allowed a further comparison between the antibody results and the conventional small-intestinal histology. METHODS: A total of 144 cases with coeliac disease [median age 19.5 years (range 0.9-81.4)], and 127 disease controls [median age 29.2 years (range 0.5-79.0)], were recruited, on the basis of biopsy, from 13 centres in nine countries. All biopsy specimens were re-evaluated and classified blindly a second time by two investigators. IgA-TTG were determined by ELISA with human recombinant antigen and IgA-EMA by an immunofluorescence test with human umbilical cord as antigen. RESULTS: The quality of the biopsy specimens was not acceptable in 29 (10.7%) of 271 cases and a reliable judgement could not be made, mainly due to poor orientation of the samples. The primary clinical diagnosis and the second classification of the biopsy specimens were divergent in nine cases, and one patient was initially enrolled in the wrong group. Thus, 126 coeliac patients and 106 controls, verified by biopsy, remained for final analysis. The sensitivity of IgA-TTG was 94% and IgA-EMA 89%, the specificity was 99% and 98%, respectively. CONCLUSIONS: Serum IgA-TTG measurement is effective and at least as good as IgA-EMA in the identification of coeliac disease. Due to a high percentage of poor histological specimens, the diagnosis of coeliac disease should not depend only on biopsy, but in addition the clinical picture and serology should be considered.

Developing and implementing all-in-one standard paediatric parenteral nutrition.

Parenteral nutrition (PN) is a feeding mode suitable for children that do not achieve requirements via the enteral route. For this intervention to be successful, healthcare professionals require: knowledge on nutrient requirements; access to an aseptic compounding facility; and a system that ensures adequate and safe delivery of PN. Previously, it was thought that individualised PN was the "gold standard" for delivering nutrients to children; however, studies have highlighted concerns regarding inadequate delivery of nutrients, prescribing and compounding errors. We, therefore, set out to develop and implement all-in-one (AIO) paediatric PN solutions. Through a systematic approach, four AIO PN solutions were developed: birth-two months of age (Ped 1); two months-10 kg (Ped 2); 11-15 kg (Ped 3); and 16-30 kg (Ped 4). We implemented them with the help of a teaching pack, over a one month time period, and reviewed usage at six months. At that time, five children initially received standard PN without electrolyte changes; but after a few days, electrolytes needed amendments, and three required individualised PN. A change to AIO PN is feasible and safe; however, some may require electrolyte changes, and there will always be those that will require individualised PN.

Osteoprotegerin in pediatric Crohn's disease and the effects of exclusive enteral nutrition.

BACKGROUND: Osteoprotegerin (OPG) may have proinflammatory roles in addition to its contribution to the maintenance of bone mass. Exclusive enteral nutrition (EEN) is an established therapy for the induction of remission in Crohn's disease (CD). The aims of this study were to ascertain serum, fecal, and mucosal expression of OPG in children with CD and to investigate the effects of EEN on OPG expression. METHODS: OPG was measured by enzyme-linked immunosorbent assay in serum, mucosal, and fecal samples collected from children with CD and controls. Fecal and Serum OPG was measured prior to and following 6-8 weeks of EEN therapy. RESULTS: Children with CD (n=82) and controls (n=45) were included. Mucosal and fecal OPG levels were elevated in CD compared to controls (P=0.018 and P<0.0001, respectively). Serum OPG was elevated in children with severe CD (P=0.005). Serum and fecal OPG levels dropped significantly following EEN therapy (P=0.0001 and P=0.002, respectively). CONCLUSIONS: Increased serum and fecal OPG are seen in active CD and likely originate from the inflamed gut. Fecal and serum OPG decrease following EEN therapy. Further investigation of OPG and related proteins in the setting of IBD is now required.
