    Low diversity of the gut microbiota in infants with atopic eczema2012Inngår i: Journal of Allergy and Clinical Immunology, ISSN 0091-6749, E-ISSN 1097-6825, Vol. 129, nr 2, s. 434-440.e2Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: It is debated whether a low total diversity of the gut microbiota in early childhood is more important than an altered prevalence of particular bacterial species for the increasing incidence of allergic disease. The advent of powerful, cultivation-free molecular methods makes it possible to characterize the total microbiome down to the genus level in large cohorts.

    Objective: We sought to assess microbial diversity and characterize the dominant bacteria in stool during the first year of life in relation to atopic eczema development.

    Methods: Microbial diversity and composition were analyzed with barcoded 16S rDNA 454-pyrosequencing in stool samples at 1 week, 1 month, and 12 months of age in 20 infants with IgE-associated eczema and 20 infants without any allergic manifestation until 2 years of age (ClinicalTrials.gov ID NCT01285830).

    Results: Infants with IgE-associated eczema had a lower diversity of the total microbiota at 1 month (P = .004) and a lower diversity of the bacterial phylum Bacteroidetes and the genus Bacteroides at 1 month (P = .02 and P = .01) and the phylum Proteobacteria at 12 months of age (P = .02). The microbiota was less uniform at 1 month than at 12 months of age, with a high interindividual variability. At 12 months, when the microbiota had stabilized, Proteobacteria, comprising gram-negative organisms, were more abundant in infants without allergic manifestation (Empirical Analysis of Digital Gene Expression in R [edgeR] test: P = .008, q = 0.02).

    Conclusion: Low intestinal microbial diversity during the first month of life was associated with subsequent atopic eczema.

    Microbiota in Functional Gastrointestinal Disorders in Infancy: Implications for Management2017Inngår i: INTESTINAL MICROBIOME: FUNCTIONAL ASPECTS IN HEALTH AND DISEASE, KARGER , 2017, Vol. 88, s. 107-115Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The complex and diverse intestinal microbiome is recognized as important in promoting human health. An altered gut microflora, referred to as dysbiosis, is increasingly recognized as having an etiologic role in a variety of conditions, including functional gastrointestinal disorders: colic in infants and irritable bowel syndrome in older children. Probiotics are defined as live microorganisms that, if ingested in sufficient amounts, restore microbial homeostasis and have a benefit on health. Randomized controlled trials indicate that probiotics can be effective in a variety of intestinal conditions, including colic and irritable bowel syndrome. Probiotics may promote gut microbial diversity, but timing of the intervention appears crucial. Strain-specific effects on colonization resistance, epithelial barrier integrity, modulation of signal transduction, impacts on innate and adaptive immune responses, and effects on visceral hyperalgesia likely explain the observed variability in various probiotic strains. In the future, probiotics are likely to be chosen for use in a defined clinical setting based on underlying mechanism(s) of action. The precise component of the probiotic agent mediating observed effects is the subject of current research. Unresolved issues relate to optimal dosages, timing of ingestion, single versus combination formulations, maintenance of viability in storage, and the merits of employing probiotic- derived products.

    The effect of interventions aimed at improving participation outcomes for children with disabilities: a systematic review2015Inngår i: Developmental Medicine & Child Neurology, ISSN 0012-1622, E-ISSN 1469-8749, Vol. 57, nr 12, s. 1093-1104Artikkel, forskningsoversikt (Fagfellevurdert)
    Abstract [en]

    Aim

    Enhancement of participation has been described as the ultimate outcome for health and educational interventions. The goal of this systematic review was to identify and critically appraise studies that aimed to improve the participation outcomes of children with disabilities.

    Method

    Nine databases that index literature from the fields of health, psychology, and education were searched to retrieve information on research conducted with children with disabilities aged between 5 years and 18 years. Articles were included if the author(s) reported that participation was an intended outcome of the intervention. The articles included were limited to those reporting high-level primary research, as defined by Australia's National Health and Medical Research Council evidence hierarchy guidelines. No restrictions were placed on the type of intervention being investigated.

    Results

    Seven randomized controlled or pseudo-randomized studies were included. Only three of these studies identified participation as a primary outcome. Both individualized and group-based approaches to enhancing participation outcomes appeared to be effective. Studies of interventions with a primary focus on body function or activity level outcomes did not demonstrate an effect on participation outcomes.

    Intepretation

    Few intervention studies have focused on participation as a primary outcome measure. Approaches using individually tailored education and mentoring programmes were found to enhance participation outcomes, while exercise programmes, where participation was a secondary outcome, generally demonstrated little effect.

    Effect of gene, environment and maternal depressive symptoms on pre-adolescence behavior problems: a longitudinal study2013Inngår i: Child and Adolescent Psychiatry and Mental Health, ISSN 1753-2000, E-ISSN 1753-2000, Vol. 7, artikkel-id 10Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND:

    Depression is a common and disabling condition with a high relapse frequency. Maternal mental health problems and experience of traumatic life events are known to increase the risk of behavior problems in children. Recently, genetic factors, in particular gene-by-environment interaction models, have been implicated to explain depressive etiology. However, results are inconclusive.

    METHODS:

    Study participants were members of the SESBiC-study. A total of 889 mothers and their children were followed during the child's age of 3 months to 12 years. Information on maternal depressive symptoms was gathered postpartum and at a 12 year follow-up. Mothers reported on child behavior and traumatic life events experienced by the child at age 12. Saliva samples were obtained from children for analysis of 5-HTTLPR and BDNF Val66Met polymorphisms.

    RESULTS:

    Multivariate analysis showed a significant association between maternal symptoms of depression and anxiety, and internalizing problems in 12-year-old children (OR 5.72, 95% CI 3.30-9.91). Furthermore, carriers of two short alleles (s/s) of the 5-HTTLPR showed a more than 4-fold increased risk of internalizing problems at age 12 compared to l/l carriers (OR 4.73, 95% CI 2.14-10.48). No gene-by-environment interaction was found and neither depressive symptoms postpartum or traumatic experiences during childhood stayed significant in the final model.

    CONCLUSIONS:

    Concurrent maternal symptoms of depression and anxiety are significant risk factors for behavior problems in children, which need to be taken into account in clinical practice. Furthermore, we found a main effect of 5-HTTLPR on internalizing symptoms in 12-year-old children, a finding that needs to be confirmed in future studies.

    Early predictors of behavioural problems in pre-schoolers: a longitudinal study of constitutional and environmental main and interaction effects2016Inngår i: BMC Pediatrics, ISSN 1471-2431, E-ISSN 1471-2431, Vol. 16, artikkel-id 76Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: The early environment is important for child development and wellbeing. Gene-by-environment studies investigating the impact of the serotonin transporter gene-linked polymorphic region (5-HTTLPR) and the Brain Derived Neurotrophic Factor (BDNF) Val66Met polymorphisms by life events on mental health and behaviour problems have been inconclusive. Methodological differences regarding sample sizes, study population, definitions of adversities and measures of mental health problems obstacle their comparability. Furthermore, very few studies included children. The aim of this study was to examine the associations between a broad range of risk factors covering pregnancy and birth, genetic polymorphism, experience of multiple life events and psychosocial environment, and child behaviour at age 3, using a comparably large, representative, population-based sample. Methods: A total of 1,106 children, and their mothers, were followed from pregnancy to age 3. Information on pregnancy and birth-related factors was retrieved from the Medical Birth Register. Questionnaires on depressive symptoms, child behaviour and child experiences of life events were filled in by the mothers. Child saliva samples were used for genotyping the 5-HTTLPR and BDNF Val66Met polymorphisms. Multiple logistic regression was used to investigate the association between psychological scales and genetic polymorphisms. Results: Symptoms of postpartum depression increased the risk of both internalizing and externalizing problems. Experience of multiple life events was also a predictor of behavioural problems across the scales. No gene-by-environment or gene-by-gene-by-environment interactions were found. Children of immigrants had an increased risk of internalizing problems and parental unemployment was significantly associated with both internalizing and externalizing type of problems. Conclusion: This study shows the importance of the psychosocial environment for psychosocial health in preschool children, and adds to the literature of null-findings of gene-by-environment effects of 5-HTTLPR and BDNF in children.

    Postnatal Peer Counseling on Exclusive Breastfeeding of Low-birthweight Filipino Infants: Results of a Randomized Controlled Trial2005Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    In a Manila hospital, 204 mothers were randomized into three groups: two intervention groups receiving home-based counseling visits, one of them (n=68) by counselors trained to use a locally developed, two-tiered program of breastfeeding counseling, and the other by counselors trained in general childcare (n=67), were compared with a control group of mothers (n=69) who did not receive any counseling. All infants were scheduled for seven visits to the hospital for follow-up. During hospital visits, maternal and infant body measurements were made and an independent interviewer asked the mothers individually to recall how the infant had been fed. One study physician, blind to participant groups, was consulted at all scheduled and unscheduled infant visits.

    At six months, 44% of the breastfeeding-counseled mothers, 7% of the childcare-counseled mothers and none of the mothers in the control group were exclusively breastfeeding. Twenty- four mothers breastfed exclusively during the first six months, of whom 22 received breastfeeding counseling and 2 had no breastfeeding counseling. Among 24 infants who were exclusively breastfed from birth to six months there were no episodes of diarrhea. All infants had gained in weight, length and head circumference. Mean maternal weight loss at six months was similar whether her breastfeeding was exclusive or partial.

    The reasons why mothers without breastfeeding counseling introduced non-breast milk feeding before six months reflected lack of knowledge and support. Breastfeeding support during the first six months focusing on how to prevent and solve breastfeeding problems, particularly during the first two weeks, will enable mothers to choose to breastfeed exclusively up to six months.

    This study has provided fundamental evidence of successful intervention by breastfeeding counseling to achieve six months of exclusive breastfeeding among term, low-birthweight infants. The locally developed training program in breastfeeding counseling, which successfully prepared volunteers to counsel mothers at home, could be incorporated into primary health care in the Philippines. Mothers who received breastfeeding counseling appreciated how this helped them to achieve their breastfeeding goals for the first six months. Improved breastfeeding practices as a result of breastfeeding counseling provided infants with protection from diarrhea and respiratory infections, contributing to their health and development.

    Necrotising Enterocolitis: epidemiology and imaging2017Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Necrotising enterocolitis (NEC) is a potentially devastating intestinal inflammation of multifactorial aetiology in premature or otherwise vulnerable neonates. Because of the broad spectrum of presentations, diagnosis and timing of surgical intervention may be challenging, and imaging needs to be an integrated part of management.

    The first four studies included in this thesis used routinely collected, nationwide register data to describe the incidence of NEC in Sweden 1987‒2009, its variation with time, seasonality, space-time clustering, and associations with maternal, gestational, and perinatal factors, and the risk of intestinal failure in the aftermath of the disease.

    Early infant survival increased dramatically during the study period. The incidence rate of NEC was 0.34 per 1,000 live births, rising from 0.26 per 1,000 live births in the first six years of the study period to 0.57 in the last five. The incidence rates in the lowest birth weights were 100‒160 times those of the entire birth cohort. Seasonal variation was found, as well as space-time clustering in association with delivery hospitals but not with maternal residential municipalities.

    Comparing NEC cases with matched controls, some factors, positively associated with NEC, were isoimmunisation, fetal distress, caesarean section, persistent ductus arteriosus, cardiac and gastrointestinal malformations, and chromosomal abnormalities. Negative associations included maternal pre-eclampsia, maternal urinary infection, and premature rupture of the membranes. Intestinal failure occurred in 6% of NEC cases and 0.4% of controls, with the highest incidence towards the end of the study period.

    The last study investigated current practices and perceptions of imaging in the management of NEC, as reported by involved specialists. There was great consensus on most issues. Areas in need of further study seem mainly related to imaging routines, the use of ultrasound, and indications for surgery.

    Developing alongside the progress of neonatal care, NEC is a complex, multifactorial disease, with shifting patterns of predisposing and precipitating causes, and potentially serious long-term complications. The findings of seasonal variation, spacetime clustering, and negative associations with antenatal exposure to infectious agents, fit into the growing understanding of the central role of bacteria and immunological processes in normal maturation of the intestinal canal as well as in the pathogenesis of NEC. Imaging in the management of NEC may be developed through future studies combining multiple diagnostic parameters in relation to clinical outcome.

    Maternal, fetal and perinatal factors associated with necrotizing enterocolitis in Sweden: A national case-control study2018Inngår i: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, PLoS ONE, ISSN 1932-6203, Vol. 13, nr 3, artikkel-id e0194352Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objective

    To analyze associations of maternal, fetal, gestational, and perinatal factors with necrotizing enterocolitis in a matched case-control study based on routinely collected, nationwide register data.

    Study design

    All infants born in 1987 through 2009 with a diagnosis of necrotizing enterocolitis in any of the Swedish national health care registers were identified. For each case up to 6 controls, matched for birth year and gestational age, were selected. The resulting study population consisted of 720 cases and 3,567 controls. Information on socioeconomic data about the mother, maternal morbidity, pregnancy related diagnoses, perinatal diagnoses of the infant, and procedures in the perinatal period, was obtained for all cases and controls and analyzed with univariable and multivariable logistic regressions for the whole study population as well as for subgroups according to gestational age.

    Results

    In the study population as a whole, we found independent positive associations with necrotizing enterocolitis for isoimmunization, fetal distress, cesarean section, neonatal bacterial infection including sepsis, erythrocyte transfusion, persistent ductus arteriosus, cardiac malformation, gastrointestinal malformation, and chromosomal abnormality. Negative associations were found for maternal weight, preeclampsia, maternal urinary infection, premature rupture of the membranes, and birthweight. Different patterns of associations were seen in the subgroups of different gestational age.

    Conclusion

    With some interesting exceptions, especially in negative associations, the results of this large, population based study, are in keeping with earlier studies. Although restrained by the limitations of register data, the findings mirror conceivable pathophysiological processes and underline that NEC is a multifactorial disease.

    Space-time clustering of necrotizing enterocolitis supports the existence of transmissible causes.2017Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    Problem Statement: Despite great efforts to prevent necrotizing enterocolitis (NEC) the incidence may in fact be increasing, and changes in the patient population over time seem to lead to changes in clinical presentation and risk factor spectrum as well. The presence of bacteria is an important prerequisite in the pathogenesis, but, rather than being caused by specific pathogens, inflammation and bacterial invasion are thought to be mediated through erroneous interaction between microbiota and innate immunity during colonization of the gut. There are, however, reports of episodic outbreaks of NEC, seasonal variation in incident rates, and clustering, suggesting a role for transmissible infectious agents or other environmental factors around the pregnant mother or newborn infant. In order to investigate evidence for such factors we have analyzed the occurrence of space-time clusters in Sweden over 23 years. Methods: A national register-based cohort of all children born between 1987 and 2009 in Sweden, diagnosed with NEC, was identified. The Knox test and Kulldorff’s scan method were used to analyze signs of space-time clusters at two geographical levels; the mother’s residential address and the delivery hospital. Time windows of seven, 14 and 21 days were used for closeness in time. Results: The Knox test showed clustering on hospital level in all studied temporal windows; seven days (p=0.022) 14 days (p=0.011) and 21 days (p=0.006), and Kulldorff’s scan method found seven significant clusters. On residential level, there was no indication of space-time interaction. When comparing two time periods, significant clustering on hospital level was found during 1987-1997, but not during 1998-2009. Conclusion: Space-time clustering was found on hospital level, but not on community level, suggesting a contagious environmental effect at and after delivery but not in the materno-fetal environment outside the hospital before birth. The decrease in clustering over time suggests that improved routines in neonatal care have minimized the risk of NEC precipitating contagions spreading between patients in the neonatal intensive care unit. The importance of such routines should not be forgotten while our efforts to bring down NEC incidence are directed towards other challenges.

    The role of imaging in the management of necrotising enterocolitis: a multispecialist survey and a review of the literature2018Inngår i: European Radiology, ISSN 0938-7994, E-ISSN 1432-1084, s. 1-11Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objectives

    To investigate current practices and perceptions of imaging in necrotising enterocolitis (NEC) according to involved specialists, put them in the context of current literature, and identify needs for further investigation.

    Methods

    Two hundred two neonatologists, paediatric surgeons, and radiologists answered a web-based questionnaire about imaging in NEC at their hospitals. The results were descriptively analysed, using proportion estimates with 95% confidence intervals.

    Results

    There was over 90% agreement on the value of imaging for confirmation of the diagnosis, surveillance, and guidance in decisions on surgery as well as on abdominal radiography as the first-choice modality and the most important radiographic signs. More variation was observed regarding some indications for surgery and the use of some ultrasonographic signs. Fifty-eight per cent stated that ultrasound was used for NEC at their hospital. Examination frequency, often once daily or more but with considerable variations, and projections used in AR were usually decided individually rather than according to fixed schedules. Predicting the need of surgery was regarded more important than formal staging.

    Conclusion

    Despite great agreement on the purposes of imaging in NEC and the most important radiographic signs of the disease, there was considerable diversity in routines, especially regarding examination frequency and the use of ultrasound. Apart from continuing validation of ultrasound, important objectives for future studies include definition of the supplementary roles of both imaging modalities in relation to other diagnostic parameters and evaluation of various imaging routines in relation to timing of surgery, complications, and mortality rate.

    School performance after preterm birth2015Inngår i: Epidemiology, ISSN 1044-3983, E-ISSN 1531-5487, Vol. 26, nr 1, s. 106-111Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: An increased risk of poor school performance for children born preterm has been shown in many studies, but whether this increase is attributable to preterm birth per se or to other factors associated with preterm birth has not been resolved. METHODS: We used data from the Swedish Medical Birth Register, the Longitudinal Integration Database for Sickness Insurance and Labor Market Study, the Swedish Multigeneration Register, and the National School Register to link records comprising the Swedish birth cohorts from 1974 through 1991. Linear regression was used to assess the association between gestational duration and school performance, both with and without controlling for parental and socioeconomic factors. In a restricted analysis, we compared siblings only with each other. RESULTS: Preterm birth was strongly and negatively correlated with school performance. The distribution of school grades for children born at 31-33 weeks was on average 3.85 (95% confidence interval = -4.36 to -3.35) centiles lower than for children born at 40 weeks. For births at 22-24 weeks, the corresponding figure was -23.15 (-30.32 to -15.97). When taking confounders into account, the association remained. When restricting the analysis to siblings, however, the association between school performance and preterm birth after week 30 vanished completely, whereas it remained, less pronounced, for preterm birth before 30 weeks of gestation. CONCLUSIONS: Our study suggests that the association between school performance and preterm birth after 30 gestational weeks is attributable to factors other than preterm birth per se.

    Long-term response to growth hormone (GH) therapy in short children with a delayed infancy childhood transition (DICT)2011Inngår i: Pediatric Research, ISSN 0031-3998, E-ISSN 1530-0447, Vol. 69, s. 504-510Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Transition of growth from infancy to childhood is associated with activation of the GH-IGF-I axis. Children with a delayed infancy-childhood-transition (ICT) are short as adults. Thus, age at ICT may impact on growth response to GH. The objective was to investigate associations between growth response to GH-treatment and ICT-timing in children with idiopathic short stature (ISS) in a randomized, controlled, multicenter trial, TRN 88-080. 147 pre-pubertal children (mean age, 11.5±1.4 yrs) were randomized to receive GH 33μg/kg/d (GH33, n=43), GH 67μg/kg/d (GH67, n=61) or no treatment (n=43). Data on growth to final height (FH) were analyzed after categorization into those with normal (n=76) or delayed ICT (n=71). Within the GH33 group, significant height gain at FH was only observed in children with a delayed ICT (p<0.001) with each month of delay corresponding to gain of 0.13 standard deviation score (SDS). For the GH67 group, the timing of the onset of the ICT had no impact on growth response. In conclusion, ISS children with a delayed ICT responded to standard-GH-dose (better responsiveness), whereas those with a normal ICT required higher doses to attain a significant height gain to FH.

    Growth Hormone Dose-Dependent Pubertal Growth: A Randomized Trial in Short Children with Low Growth Hormone Secretion2014Inngår i: Hormone Research in Paediatrics, ISSN 1663-2818, E-ISSN 1663-2826, Vol. 82, nr 3, s. 158-170Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background/Aims: Growth hormone (GH) treatment regimens do not account for the pubertal increase in endogenous GH secretion. This study assessed whether increasing the GH dose and/or frequency of administration improves pubertal height gain and adult height (AH) in children with low GH secretion during stimulation tests, i. e. idiopathic isolated GH deficiency. Methods: A multicenter, randomized, clinical trial (No. 88-177) followed 111 children (96 boys) at study start from onset of puberty to AH who had received GH(33) mu g/kg/day for >= 1 year. They were randomized to receive 67 mu g/kg/day (GH(67)) given as one (GH(67x1); n = 35) or two daily injections (GH(33x2); n = 36), or to remain on a single 33 mu g/kg/day dose (GH(33x1); n = 40). Growth was assessed as height SDS gain for prepubertal, pubertal and total periods, as well as AH SDS versus the population and the midparental height. Results: Pubertal height SDS gain was greater for patients receiving a high dose (GH(67), 0.73) than a low dose (GH(33x1), 0.41, p < 0.05). AH(SDS) was greater on GH(67) (GH(67x1), -0.84; GH(33x2), -0.83) than GH(33) (-1.25, p < 0.05), and height SDS gain was greater on GH(67) than GH(33) (2.04 and 1.56, respectively; p < 0.01). All groups reached their target height SDS. Conclusion: Pubertal height SDS gain and AH SDS were dose dependent, with greater growth being observed for the GH(67) than the GH(33) randomization group; however, there were no differences between the once-and twice-daily GH(67) regimens.

    Mortality Is Not Increased in Recombinant Human Growth Hormone-treated Patients When Adjusting for Birth Characteristics2016Inngår i: Journal of Clinical Endocrinology and Metabolism, ISSN 0021-972X, E-ISSN 1945-7197, Vol. 101, nr 5, s. 2149-2159Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objective: This study aimed to investigate whether reported high mortality in childhood recombinant human GH (rhGH)-treated patients was related to birth-characteristics and/or rhGH treatment.

    Design and Setting: We sought to develop a mortality model of the Swedish general population born between 1973 and 2010, using continuous-hazard functions adjusting for birth characteristics, sex, age intervals, and calendar year to estimate standardized mortality ratio (SMR) and to apply this model to assess expected deaths in Swedish rhGH-treated patients with idiopathic isolated GH deficiency (IGHD), idiopathic short stature (155) or born small for gestational age (SGA).

    Participants: The general population: Swedish Medical Birth Register (1973-2010: 1 880 668 males; 1 781 131 females) and Cause of Death Register (1985-2010).

    Intervention Population: Three thousand eight hundred forty-seven patients starting rhGH treatment between 1985 and 2010 and followed in the National GH Register and/or in rhGH trials diagnosed with IGHD (n = 1890), ISS (n = 975), or SGA (n=982).

    Main Outcome Measures: Death.

    Results: Using conventional models adjusting for age, sex, and calendar-year, the SMR was 1.43 (95% confidence interval, 0.89-2.19), P = .14, observed/expected deaths 21/14.68. The rhGH population differed (P < .001) from the general population regarding birth weight, birth length, and congenital malformations.

    Application of an Advanced Model: When applying the developed mortality model of the general population, the ratio of observed/expected deaths in rhGH-treated patients was 21/21.99; SMR = 0.955 (0.591-1.456)P = .95.

    Model Comparison: Expected number of deaths were 14.68 (14.35-14.96) using the conventional model, and 21.99 (21.24-22.81) using the advanced model, P < .001, which had at all ages a higher gradient of risk per SD of the model, 24% (range, 18-42%; P < .001).

    Conclusions: Compared with the general Swedish population, the ratio of observed/expected deaths (21/21.99) was not increased in childhood rhGH-treated IGHD, ISS, and SGA patients when applying an advanced sex-specific mortality model adjusting for birth characteristics.

    Heart rate variability in children with fontan circulation: lateral tunnel and extracardiac conduit2012Inngår i: Pediatric Cardiology, ISSN 0172-0643, E-ISSN 1432-1971, Vol. 33, nr 2, s. 307-315Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The technique in Fontan surgery has developed from the lateral tunnel (LT) toward the extracardiac conduit (EC) used to reduce long-term complications such as atrial arrhythmia and sinus node dysfunction. Heart rate variability (HRV) examines cardiac nervous activity controlling the sinus node. This study aimed to investigate HRV in a cohort of children with univentricular hearts, focusing on the relation between HRV and surgical procedure. For 112 children with Fontan circulation, HRV was analyzed using power spectral analysis. Spectral power was determined in three regions: very-low-frequency (VLF), low-frequency (LF), and high-frequency (HF) regions. Patients were compared with 66 healthy controls subject. Patients with LT were compared with patients who had EC. The children with Fontan circulation showed a significantly reduced HRV including total power (P < 0.0001), VLF (P < 0.0001), LF (P < 0.0001), and HF (P = 0.001) compared with the control subjects. The LT and EC patients did not differ significantly. Reduced HRV was found in both the LT and EC patients. In terms of HRV reduction, EC was not superior to LT.

    Overweight and obese children have lower cortisol levels than normal weight children2014Inngår i: Acta Paediatrica, ISSN 0803-5253, E-ISSN 1651-2227, Vol. 103, nr 3, s. 295-299Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    AIM: The stress hormone cortisol is vital to survival, and a disturbed circadian rhythm can be deleterious to health. However, little is known about cortisol levels in healthy children. The aim of this study was to examine cortisol levels in relation to body mass index (BMI), age and sex. METHODS: Salivary samples were collected in early morning, late morning and evening, on four consecutive days, from 342 children aged 6-12years using Salivette((R)) tubes. Samples were analysed using a commercial enzyme immunoassay (EIA). School nurses measured the children's height and weight, and these measurements were used to calculate their BMI. RESULTS: The children displayed a circadian rhythm in cortisol secretion, with morning zeniths and evening nadirs. Average cortisol levels in early morning, late morning and evening were significantly lower in overweight and obese children than in their normal weight counterparts. Cortisol levels did not vary significantly with age or sex. CONCLUSION: Our findings may suggest cortisol suppression in overweight and obese children. We found no evidence that sex or age influences cortisol levels. These findings highlight the need for further research on the relationship between stress and obesity in children.

    Placental gene expression of inflammatory markers and growth factors: a case control study of obese and normal weight women2015Inngår i: Journal of Perinatal Medicine, ISSN 0300-5577, E-ISSN 1619-3997, Vol. 43, nr 2, s. 159-164Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objective: To survey the placental gene expression of inflammatory markers and growth factors in non-smoking obese women with an uncomplicated pregnancy without associated morbidity and delivery at term compared with normal weight women.

    Methods: Placental tissue samples from 32 obese women (body mass index, BMI >= 35.0 kg/m(2)) were compared with samples from 94 normal weight women (BMI 18.5-25.0 kg/m(2)) matched for age (+/- 1 year), gestational age (+/- 3 days), parity and mode of delivery. Semi-quantitative reverse transcription polymerase chain reaction (RT-PCR) was used to analyse toll receptor-2 and -4, interleukin-6 and -8, tumour necrosis factor-alpha, leptin, adiponectin, insulin-like growth factor-1 and -2, hepatocyte growth factor, hepatocyte growth factor receptor and insulin receptor.

    Results: There was no significant difference in gene expression in placental tissue samples from obese and normal weight women.

    Conclusion: We found no difference in the occurrence of inflammatory marker and growth factor mRNA levels in placental tissue samples from a large group of obese women without associated morbidity and with healthy infants compared to a closely matched control group of healthy normal weight women. Compared with the previous studies, this anomalous finding may be explained by the absence of associated morbidity in the obese women in our study.

    Adipocytokines in placenta and cord blood in relation to maternal obesity, and foetal and postnatal growth of the child2015Inngår i: Hormone Research in Paediatrics, ISSN 1663-2818, E-ISSN 1663-2826, Vol. 82, nr Suppl. 1, s. 47-48Artikkel i tidsskrift (Annet vitenskapelig)
    Abstract [en]

    Background: The nutritional and hormonal state in utero may be a link between maternal obesity and obesity in the offspring. The gene expression in placentae in pregnancies complicated by diabetes is reduced for leptin, but increased for ghrelin. It is not known whether these genes’ expressions in placentae are altered in maternal obesity.

    Objectives and hypotheses: To compare obese and normal-weight women and their children concerning gene expressions of leptin and ghrelin in placentae; leptin, ghrelin, adiponectin, and C-peptide levels in cord blood, birth size and postnatal growth. Changes in the expression of these adipocytokines may lead to an altered hypothalamic sensitivity to leptin and ghrelin resulting in an increased risk of obesity in the offspring.

    Method: 32 women with pre-pregnancy obesity, but otherwise healthy, were compared to 32 matched, normal-weight controls. Full-term placenta biopsies were analysed with qPCR for leptin mRNA and ghrelin mRNA. Cord blood samples were examined with ELISA for leptin, ghrelin, adiponectin, and C-peptide concentrations. Birth size and postnatal growth of the children were collected from clinical registers at the Child Health Care Units.

    Results: The leptin and ghrelin gene expressions in placentae did not differ between obese and normal-weight women. The leptin concentration in cord blood was higher in children of obese mothers (P=0.021). It correlated with birth weight Z-score (r=0.467, P<0.001) and C-peptide level in cord blood (r=0.446, P<0.001). Children of obese women were slightly heavier at birth, but postnatal growth did not differ between groups. Children with birth weight  ≤−0.67 Z-score had higher ghrelin levels in cord blood than heavier children (P=0.042). The leptin level in cord blood correlated negatively with weight gain at 6 months (r=−0.332, P=0.009). The ghrelin level in cord blood correlated with weight gain at 3 months in girls (r=0.611, P=0.001), but not in boys. The adiponectin level in cord blood correlated negatively with length gain at 3 years in the obese group (r=−0.571, P=0.033), but not in the normal-weight group.

    Conclusion: Leptin and ghrelin placental gene expressions are not altered in obese women, but foetal adipocytokine production may influence early postnatal growth, possibly by influencing hunger signalling or insulin levels

    Adherence to Swedish guidelines for pain treatment in relation to pediatric tonsil surgery: A survey of the multidisciplinary team2017Inngår i: International Journal of Pediatric Otorhinolaryngology, ISSN 0165-5876, E-ISSN 1872-8464, Vol. 101, s. 123-131Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Pain management in children after tonsil surgery is essential, and optimal pain treatment has been discussed for many years. Data from the National Tonsil Register in Sweden (NTRS) and a national mapping system have demonstrated the need for national pain treatment guidelines for pediatric tonsil surgery. As a result, Swedish national guidelines, together with updated patient information on the website tonsilloperation.se, were developed and implemented in 2013.

    Objectives The objective of this study was to evaluate the professionals’ opinions of and adherence to pain treatment guidelines for pediatric tonsil surgery patients in a two-year follow-up.

    Method: This descriptive cross-sectional study was based on data from an inter-professional questionnaire, which was validated by an expert group using a content validity index (S-CVI 0.93). The questionnaire was sent to all Swedish ear, nose and throat (ENT) departments (n=49) that the NTRS identified as performing tonsil surgery on children younger than 18 years of age. In each clinic, we asked for responses from staff in each of the following professions: ENT physicians, anesthesia physicians, registered nurse anesthetists, and registered nurses in the ENT departments.

    Results: Respondents from 48 ENT departments participated, and 139/163 (85%) completed questionnaires were returned. The guidelines were reported as being clear, ensuring patient safety and providing optimal pharmacological treatment. Treatment was given according to the guidelines: Half of the departments gave pre- or intraoperative treatment with clonidine, betamethasone and high-dose paracetamol (acetaminophen). A multimodal pain approach (paracetamol and COX inhibitors) after hospital discharge was prescribed by all departments after tonsillectomy and, more extensively, after tonsillotomy. One-third of the departments prescribed paracetamol with a higher normal dose for the first three postoperative days. Half of the departments prescribed rescue analgesics, clonidine or opioids after tonsillectomy. None of the departments prescribed codeine or tramadol, drugs that are discouraged in the guidelines. The majority of the departments used the website tonsilloperation.se to provide information to the patients and their caregivers.

    Conclusion: The respondents' opinions of and the ENT departments adherence to the Swedish national guidelines were considered to be good. The national implementation process in Sweden has impacted the manner in which ENT departments treat pain after tonsil surgery.

    High Blood Pressure in Children with Hydronephrosis2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    The most common cause of secondary hypertension is intrinsic renal disease, but little is known about the influence of hydronephrosis on blood pressure. In this thesis, the risk of development of hypertension in children with hydronephrosis was studied.

    Experimental and clinical studies were combined in order to investigate the risk of developing elevated blood pressure following conservative treatment of hydronephrosis, and to further explore underlying mechanisms. We started with a clinical study in children (study I), which in agreement with previous experimental studies, showed that blood pressure was lowered by surgical management of hydronephrosis. In parallel, an experimental study was conducted (study II) to investigate the involvement of renal sympathetic nerve activity in development of hypertension following induction of hydronephrosis caused by pelvo-ureteric junction obstruction. Renal denervation of the obstructed kidney attenuated hypertension and restored the renal excretion pattern, effects that were associated with reduced activity of both renal NADPH oxidase derived oxidative stress and components of the renin-angiotensin-aldosterone system.

    Based on the findings in studies I and II, we continued our studies in children with hydronephrosis, and including two control groups as comparisons with the hydronephrotic group (study III). In the same study, we further investigated potential mechanism(s) of hypertension by analyzing markers of oxidative stress and nitric oxide homeostasis in both urine and blood samples. We demonstrated increased arterial pressure and oxidative stress in children with hydronephrosis compared with healthy controls, which was restored to normal levels by surgical correction of the obstruction. Finally, in a retrospective cohort study, blood pressure of adult patients undergoing surgical management of hydronephrosis due to pelvo-ureteric junction obstruction was assessed (study IV). Similar to that demonstrated in the pediatric hydronephrotic population, blood pressure was significantly reduced by relief of the obstruction. In addition, blood pressure was increased again if the hydronephrosis recurred, and was reduced again following re-operation.

    It is concluded that conservative management of hydronephrosis in children is associated with a risk for development of high blood pressure, which can be reduced or even normalized by relief of the obstruction. The mechanism(s), at least in part, is coupled to increased oxidative stress.

    Surgical treatment reduces blood pressure in children with unilateral congenital hydronephrosis2015Inngår i: Journal of Pediatric Urology, ISSN 1477-5131, E-ISSN 1873-4898, Vol. 11, nr 2, s. 91.e1-91.e6Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objective Renal disorders can cause hypertension, but less is known about the influence of hydronephrosis on blood pressure. Hydronephrosis due to pelvo-ureteric junction obstruction (PUJO) is a fairly common condition (incidence in newborns of 0.5-1%). Although hypertensive effects of hydronephrosis have been suggested, this has not been substantiated by prospective studies in humans [1-3]. Experimental studies with PUJO have shown that animals with induced hydronephrosis develop salt-sensitive hypertension, which strongly correlate to the degree of obstruction [4-7]. Moreover, relief of the obstruction normalized blood pressure [8]. In this first prospective study our aim was to study the blood pressure pattern in pediatric patients with hydronephrosis before and after surgical correction of the ureteral obstruction. Specifically, we investigated if preoperative blood pressure is reduced after surgery and if split renal function and renographic excretion curves provide any prognostic information. Patients and methods Twelve patients with unilateral congenital hydronephrosis were included in this prospective study. Ambulatory blood pressure (24 h) was measured preoperatively and six months after surgery. Preoperative evaluations of bilateral renal function by Tc99m-MAG3 scintigraphy, and renography curves, classified according to O'Reilly, were also performed. Results As shown in the summary figure, postoperative systolic (103 +/- 2 mmHg) and diastolic (62 +/- 2 mmHg) blood pressure were significantly lower than those obtained preoperatively (110 +/- 4 and 69 +/- 2 mmHg, respectively), whereas no changes in circadian variation or pulse pressure were observed. Renal functional share of the hydronephrotic kidney ranged from 11 to 55%. There was no correlation between the degree of renal function impairment and the preoperative excretory pattern, or between the preoperative excretory pattern and the blood pressure reduction postoperatively. However, preoperative MAG3 function of the affected kidney correlated with the magnitude of blood pressure change after surgery. Discussion Correction of the obstruction lowered blood pressure, and the reduction in blood pressure appeared to correlate with the degree of renal functional impairment, but not with the excretory pattern. Thus, in the setting of hypertension, it appears that the functional share of the hydronephrotic kidney should be considered an indicator of the need for surgery, whereas the renography curve is less reliable. The strength of the present study is the prospective nature and that ambulatory blood pressure monitoring was used. Future longitudinal prolonged follow-up studies are warranted to confirm the present findings, and to understand if a real nephrogenic hypertension with potential necessity of treatment will develop. Conclusion This novel prospective study in patients with congenital hydronephrosis demonstrates a reduction in blood pressure following relief of the obstruction. Based on the present results, we propose that the blood pressure level should also be taken into account when deciding whether to correct hydronephrosis surgically or not.

    Experiences of facilitators or barriers in driving education from learner and novice drivers with ADHD or ASD and their driving instructors2017Inngår i: Developmental Neurorehabilitation, ISSN 1751-8423, E-ISSN 1751-8431, Vol. 20, nr 2, s. 59-67Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Little is known about whether individuals with autism spectrum disorder (ASD) or attention deficit hyperactive disorder (ADHD) experience any specific facilitators or barriers to driving education.

    Objective: To explore the facilitators or barriers to driving education experienced by individuals with ASD or ADHD who obtained a learner’s permit, from the perspective of the learner drivers and their driving instructors.

    Methods: Data were collected from 33 participants with ASD or ADHD, and nine of their driving instructors.

    Results: Participants with ASD required twice as many driving lessons and more on-road tests than those with ADHD. Participants with ADHD repeated the written tests more than those with ASD. Driving license theory was more challenging for individuals with ADHD, whilst individuals with ASD found translating theory into practice and adjusting to “unfamiliar” driving situations to be the greatest challenges.

    Conclusion: Obtaining a driving license was associated with stressful training experience.

    Early Detection and Treatment for Children: Experiences and outcome of implementation at a pediatric hospital2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Early recognition of severely ill children is necessary to prevent serious adverse events and unexpected death. To promote patient safety the Early Detection and Treatment Program for Children (EDT-C) was developed at a University Children’s Hospital in Sweden. This program consists of validated tools for communication and teamwork combined with the Pediatric Early Warning Score (PEWS) and guidelines for recommended actions. Ward specific guidelines were developed and EDT-C instructors were trained. The aims were to describe healthcare professionals’ experience of caring for acutely, severely ill children (Study I) and to evaluate the implementation of EDT-C (Study II, III, IV). The Promoting Action on Research Implementation in Health Services (PARiHS) framework guided both implementation and the research study.

    Before introducing the EDT-C, focus group interviews were performed to explore healthcare professionals’ experience of caring for acutely, severely ill children. A context assessment, using the Alberta Context Tool (ACT) was also conducted. After implementation, a retrospective review of the electronic patient records (EPR) to assess adherence to guidelines were carried out. Instructors’ and healthcare professionals’ experiences from the implementation of EDT-C were gathered through individual interviews. To evaluate the introduction of EDT-C in relation to admission and stay at intensive care a retrospective before-after study using EPR data was performed. Interviews were analyzed using qualitative content analysis and descriptive statistical methods were utilized for quantitative data.

    The caring for acutely severely ill children was described as being in a multifaceted area of tension with paradoxical elements where contradictory emotions emerged. According to documentation, children at a very high risk of clinical deterioration according to PEWS were identified. Adherence to actions prescribed in guidelines varied.

     Healthcare professionals and instructors described EDT-C as suitable for clinical practice and that it created a more structured way of working. It was furthermore described that PEWS measurement had become routine practice at the hospital.

    EDT-C can lead to increased knowledge about early detection of deterioration, strengthen the healthcare in their profession, optimize treatment and teamwork and thereby has potential to increase patient safety for children treated in hospitals.

    Increased intensive care admission rate after introduction of Early Detection and Treatment program for Children and the establishment of a pediatric intensive care unit at a tertiary hospital in SwedenInngår i: Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objective: To evaluate the introduction of an Early Detection and Treatment program- Children (EDT-C) including a paediatric early warning score (PEWS) in relation to admission and length of stay at intensive care unit (ICU). Design: Before-after study utilizing data from the Electronic Patient Record (EPR) system, comparing outcomes over a total time period of 60 months between April 2010 and September 2015. Setting: A Swedish tertiary hospital. Patients: A total of 16,283 paediatric patients were included over the study period. Interventions: EDT-C including PEWS Measurements and Main Results: The following variables were extracted from the EPR data: 1) Admissions to paediatric wards 2) Length of stay at paediatric wards 3) Admissions to intensive care units 4) Length of stay at intensive care unit 5) Diagnosis. Intensive care unit admission increased from 5.0% (440/8746) before to 10.2 % (772/7537) after the introduction of the EDT-C (p<0.01). Mean treatment time at ICU did not change (41.0 vs 48.3 hours, p=0.23). Conclusion: The introduction of EDT-C including PEWS, in conjunction with the establishment of a paediatric intensive care unit at the hospital, resulted in an increased intensive care admittance rate among paediatric in-patients.

    Implementation of Pediatric Early Warning Score: Adherence to Guidelines and Influence of Context2018Inngår i: Journal of Pediatric Nursing: Nursing Care of Children and Families, ISSN 0882-5963, E-ISSN 1532-8449, Vol. 38, s. 33-39Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    PURPOSE: To describe data of Pediatric Early Warning Score (PEWS) registrations and to evaluate the implementation of PEWS by examining adherence to clinical guidelines based on measured PEWS, and to relate findings to work context.

    DESIGN AND METHODS: PEWS, as a part of a concept called Early Detection and Treatment-Children (EDT-C) was implemented at three wards at a Children's Hospital in Sweden. Data were collected from the Electronic Patient Record (EPR) retrospectively to assess adherence to guidelines. The Alberta Context Tool (ACT) was used to assess work context among healthcare professionals (n=110) before implementation of EDT-C.

    RESULTS: The majority of PEWS registrations in EPR were low whereas 10% were moderate to high. Adherences to ward-specific guidelines at admission and for saturation in respiratory distress were high whereas adherence to pain assessment was low. There were significant differences in documented recommended actions between wards. Some differences in leadership and evaluation between wards were identified.

    CONCLUSIONS: Evaluation of PEWS implementation indicated frequent use of the tool despite most scores being low. High scores (5-9) occurred 28 times, which may indicate that patients with a high risk of clinical deterioration were identified. Documentation of the consequent recommended actions was however incomplete and there was a large variation in adherence to guidelines. Contextual factors may have an impact on adherence.

    PRACTICE IMPLICATIONS: EDT-C can lead to increased knowledge about early detection of deterioration, strengthen nurses as professionals, optimize treatment and teamwork and thereby increase patient safety for children treated in hospitals.

    Lactase persistence and milk consumption are associated with body height in Swedish preadolescents and adolescents2011Inngår i: Food & Nutrition Research, ISSN 1654-6628, E-ISSN 1654-661X, Vol. 55Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: Body height is a classic polygenic trait. About 80%-90% of height is inherited and 10%-20% owed to environmental factors, of which the most important ones are nutrition and diseases in preadolescents and adolescents.

    OBJECTIVE: The aim of this study was to explore potential relations between the LCT (lactase) C>T-13910 polymorphism, milk consumption, and body height in a sample of Swedish preadolescents and adolescents.

    DESIGN: In a cross-sectional study, using a random sample of preadolescents and adolescents (n = 597), dietary intakes were determined. Anthropometric measurements including sexual maturity (Tanner stage) and birth weight were assessed. Parental body height and socio-economic status (SES) were obtained by questionnaires. Genotyping for the LCT C>T-13910 polymorphism that renders individuals lactase persistent (LP) or lactase non-persistent (LNP) was performed by DNA sequencing. Stepwise backward multivariate linear regression was used.

    RESULTS: Milk consumption was significantly and positively associated with body height (β = 0.45; 95% CI: 0.040, 0.87, p = 0.032). Adjustments were performed for sex, parental height, birth weight, body mass index (BMI), SES, and Tanner stage. This model explains 90% of the observed variance of body height (adjusted R(2) = 0.89). The presence of the -13910 T allele was positively associated with body height (β = 2.05; 95% CI: 0.18, 3.92, p = 0.032).

    CONCLUSIONS: Milk consumption is positively associated with body height in preadolescents and adolescents. We show for the first time that a nutrigenetic variant might be able to explain in part phenotypic variation of body height in preadolescents and adolescents. Due to the small sample size further studies are needed.

    Mothers’ opinions on being asked about exposure to intimate partner violence in child healthcare centres in Sweden2018Inngår i: Journal of Child Health Care, ISSN 1367-4935, E-ISSN 1741-2889, Vol. 22, nr 2, s. 228-237Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Intimate partner violence (IPV) constitutes a hidden health risk for exposed mothers and children. In Sweden, screening for IPV in healthcare has only been routine during pregnancy, despite an increase in IPV following childbirth. The arguments against routine questions postpartum have concerned a lack of evidence of beneficial effects as well as fear of stigmatizing women or placing abused women at further risk. Increased understanding of women’s attitudes to routine questions may allay these fears. In this study, 198 mothers in 12 child healthcare centres (CHCs) filled in a short questionnaire about their exposure and received information on IPV at a regular baby check-up visit. The mothers’ lifetime prevalence of exposure to IPV was 16%. One hundred and twenty-eight mothers participated in a telephone interview, giving their opinion on the screening experience. The intervention was well-received by most of the mothers who reported that questions and information on IPV are essential for parents, considering the health risks for children, and that the CHC is a natural arena for this. Necessary prerequisites were that questioning be routine to avoid stigmatizing and be offered in privacy without the partner being present.

    Factors associated with discontinuation of breastfeeding before 1 month of age2012Inngår i: Acta Paediatrica, ISSN 0803-5253, E-ISSN 1651-2227, Vol. 101, nr 1, s. 55-60Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: Breastfeeding is associated with many benefits for both mother and child. Initiation rates are high in Sweden. Recently a slight decline is seen.

    AIM: The aim of this study was to assess factors associated with discontinuation of breastfeeding during the first 4 weeks.

    METHOD: A population-based longitudinal birth cohort study recruiting from 2007 to 2008 in south-western Sweden. At the first visit to the child health centre, parents were asked to complete a questionnaire. Also, the infants' height, weight, head and waist circumference were collected. Response rate was 69.2%.

    RESULTS: Twenty-seven per cent of mothers had breastfeeding problems. In a multivariate analysis, there was a negative correlation between breastfeeding and use of pacifier (OR 3.72; CI 2.09-6.63), maternal smoking (OR 2.09; CI 1.08-4.05) and breastfeeding problems (OR 2.54; CI 1.73-3.71). Breastfeeding problems were correlated with poor sucking technique (OR 2.96; CI 2.14-4.07), support from maternity ward (OR 2.56; CI 2.05-3.19) and perceived poor weight gain (OR 1.37; CI 1.00-1.86).

    CONCLUSION: Many mothers reported breastfeeding problems that are associated with an early cessation. This is preventable with support, but the timing is crucial. To promote breastfeeding, the support from the child health centres must be tailored with the maternal perspective in mind.

    Development of heart block in children of SSA/SSB-autoantibody-positive women is associated with maternal age and displays a season-of-birth pattern2012Inngår i: Annals of the Rheumatic Diseases, ISSN 0003-4967, E-ISSN 1468-2060, Vol. 71, nr 3, s. 334-340Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    OBJECTIVE: Congenital heart block may develop in the fetuses of Ro/SSA-positive and La/SSB-positive mothers. Recurrence rates of only 10-20% despite persisting maternal antibodies indicate that additional factors are critical for the establishment of heart block. The authors investigated the influence of other maternal and fetal factors on heart block development in a Swedish population-based cohort.

    METHODS: The influence of fetal gender, maternal age, parity and time of birth on heart block development was analysed in 145 families, including Ro/La-positive (n=190) and Ro/La-negative (n=165) pregnancies.

    RESULTS: There was a recurrence rate of 12.1% in Ro/La-positive women, and no recurrence in Ro/La-negative women. Fetal gender and parity did not influence the development of heart block in either group. Maternal age in Ro/La-positive pregnancies with a child affected by heart block was, however, significantly higher than in pregnancies resulting in babies without heart block (p<0.05).Seasonal timing of pregnancy influenced the outcome. Gestational susceptibility weeks 18-24 occurring during January-March correlated with a higher proportion of children with heart block and lower vitamin D levels during the same period in a representative sample of Swedish women and a corresponding higher proportion of children with heart block born in the summer (p<0.02). Maternal age or seasonal timing of pregnancy did not affect the outcome in Ro/La-negative pregnancies.

    CONCLUSION: This study identifies maternal age and seasonal timing of pregnancy as novel risk factors for heart block development in children of Ro/La-positive women. These observations may be useful for counselling when pregnancy is considered.

    Validity and test-retest reliability of Children's Hand-use Experience Questionnaire in children with unilateral cerebral palsy2016Inngår i: Developmental Medicine & Child Neurology, ISSN 0012-1622, E-ISSN 1469-8749, Vol. 58, nr 7, s. 743-749Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Aim: To investigate the validity of the internet-based version of the Children's Hand-use Experience Questionnaire (CHEQ) by testing the new four-category rating scale, internal structure, and test-retest reliability.

    Method: Data were collected for 242 children with unilateral cerebral palsy (CP) (137 males and 105 females; mean age 9y 10mo, SD 3y 5mo, range 6-18y). Twenty children from the study sample (mean age 11y 8mo, SD 3y 10mo) participated in a retest within 7 to 14 days. Validity was tested by Rasch analysis based on a rating scale model and test-retest reliability by Kappa analysis and intraclass correlation coefficient (ICC).

    Results: The four-category rating scale was within recommended criteria for rating scale structure. One item was removed because of misfit. CHEQ showed good scale structure according to the criteria. The effective operational range was >90% for two of the CHEQ scales. Test-retest reliability for the three CHEQ scales was: grasp efficacy, ICC=0.91; time taken, ICC=0.88; and feeling bothered, ICC=0.91.

    Interpretation: The internet-based CHEQ with a four-category rating scale is valid and reliable for use in children with unilateral CP. Further studies are needed to investigate the validity of the internet-based version of CHEQ for children with upper limb reduction deficiency or obstetric brachial plexus palsy and the validity of the recommended improvements to the current version.

    Maternal country of birth and previous pregnancies are associated with breast milk characteristics2009Inngår i: Pediatric Allergy and Immunology, ISSN 0905-6157, E-ISSN 1399-3038, Vol. 20, nr 1, s. 19-29Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Populations in high infectious exposure countries are at low risk of some immune-mediated diseases such as Crohn’s disease and allergy. This low risk is maintained upon immigration to an industrialized country, but the offspring of such immigrants have a higher immune-mediated disease risk than the indigenous population. We hypothesize that early life exposures in a developing country shape the maternal immune system, which could have implications for the offspring born in a developed country with a low infectious load. The aim of this study was to investigate if exposures in childhood (indicated by country of origin) and subsequent exposures influence immunologic characteristics relevant to stimulation of offspring. Breast milk components among 64 mothers resident in Sweden, 32 of whom immigrated from a developing country, were examined using the ELISA and Cytometric Bead Array methods. Immigrants from a developing country had statistically significantly higher levels of breast milk interleukin-6 (IL-6), IL-8 and transforming growth factor-β1. A larger number of previous pregnancies were associated with down-regulation of several substances, statistically significant for soluble CD14 and IL-8. The results suggest that maternal country of birth may influence adult immune characteristics, potentially relevant to disease risk in offspring. Such a mechanism may explain the higher immune-mediated disease risk among children of migrants from a developing to developed country. Older siblings may influence disease risk through the action of previous pregnancies on maternal immune characteristics.

    Assessment of continuous pain in newborns admitted to NICUs in 18 European countries2017Inngår i: Acta Paediatrica, ISSN 0803-5253, E-ISSN 1651-2227, Vol. 106, nr 8, s. 1248-1259Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Aim: Continuous pain occurs routinely, even after invasive procedures, or inflammation and surgery, but clinical practices associated with assessments of continuous pain remain unknown.

    Methods: A prospective cohort study in 243 Neonatal Intensive Care Units (NICUs) from 18 European countries recorded frequency of pain assessments, use of mechanical ventilation, sedation, analgesia, or neuromuscular blockade for each neonate upto 28 days after NICU admission.

    Results: Only 2113/6648 (31·8%) of neonates received assessments of continuous pain, occurring variably among tracheal ventilation (TrV, 46·0%), noninvasive ventilation (NiV, 35·0%), and no ventilation (NoV, 20·1%) groups (p<0·001). Daily assessments for continuous pain occurred in only 10·4% of all neonates (TrV: 14·0%, NiV: 10·7%, NoV: 7·6%; p<0·001). More frequent assessments of continuous pain occurred in NICUs with pain guidelines, nursing champions, and surgical admissions prompted (all p<0·01), and for newborns <32 weeks gestational age, those requiring ventilation, or opioids, sedatives-hypnotics, general anesthetics (O-SH-GA) (all p<0·001), or surgery (p=0·028). Use of O-SH-GA drugs increased the odds for pain assessment in the TrV (OR:1·60, p<0·001) and NiV groups (OR:1·40, p<0·001).

    Conclusion: Assessments of continuous pain occurred in less than one-third of NICU admissions, and daily in only 10% of neonates. NICU clinical practices should consider including routine assessments of continuous pain in newborns.

    Pain assessment practices in Swedish and Norwegian neonatal care units2017Inngår i: Scandinavian Journal of Caring Sciences, ISSN 0283-9318, E-ISSN 1471-6712Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: The use of measurement scales to assess pain in neonates is considered a prerequisite for effective management of pain, but these scales are still underutilised in clinical practice.

    AIM: The aim of this study was to describe and compare pain assessment practices including the use of pain measurement scales in Norwegian and Swedish neonatal care units.

    METHODS: A unit survey investigating practices regarding pain assessment and the use of pain measurement scales was sent to all neonatal units in Sweden and Norway (n = 55). All Norwegian and 92% of Swedish units responded.

    RESULTS: A majority of the participating units (86.5%) assessed pain. Swedish units assessed and documented pain and used pain measurement scales more frequently than Norwegian units. The most frequently used scales were different versions of Astrid Lindgren's Pain Scale (ALPS) in Sweden and Echelle Douleur Inconfort Noveau-Ne (EDIN), ALPS and Premature Infant Pain Profile (PIPP) in Norway. Norwegian head nurses had more confidence in their pain assessment method and found the use of pain measurement scales more important than their Swedish colleagues.

    CONCLUSION: The persisting difference between Swedish and Norwegian units in pain assessment and the use of pain measurement scales are not easily explained. However, the reported increased availability and reported use of pain measurement scales in neonatal care units in both countries may be seen as a contribution towards better awareness and recognition of pain, better pain management and potentially less suffering for vulnerable neonates.

    Decrease in adiponectin levels correlates to growth response in growth hormone-treated children2009Inngår i: Hormone Research, ISSN 0301-0163, E-ISSN 1423-0046, Vol. 71, nr 4, s. 213-218Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND/AIMS: Adiponectin is secreted by adipose tissue and circulates in human plasma at high levels. Decreased adiponectin levels are associated with insulin resistance and obesity. The aim of this study was to investigate whether changes in serum adiponectin levels are related to the growth response, insulin levels and insulin resistance during growth hormone (GH) treatment. METHODS: The study included 94 short prepubertal children (19 girls and 75 boys). The mean age at the start of daily GH injections was 9.04 +/- 2.38 years. Adiponectin levels in serum were measured using an ELISA. RESULTS: At baseline, adiponectin correlated with the first-year growth response (r = 0.26, p = 0.012). Adiponectin decreased significantly after 1 week, 3 months and 1 year from 14.5 +/- 5.71 to 13.1 +/- 5.22 (p < 0.0001), 10.3 +/- 4.82 (p < 0.0001) and 12.5 +/- 5.34 microg/ml (p < 0.0001), respectively. There were significant correlations between the first-year growth response and the decrease in adiponectin levels after 3 months and 1 year (r = -0.38, p < 0.0001 and r = -0.47, p < 0.0001, respectively). No correlations between adiponectin, insulin and the homeostasis model assessment of insulin resistance were seen. CONCLUSIONS: GH treatment in prepubertal children decreases serum adiponectin levels, and the decrease is correlated to the growth response. No correlations between adiponectin and insulin levels or insulin resistance were found.

    Introducing the 6-4-0 fasting regimen and the incidence of prolonged preoperative fasting in children2018Inngår i: Pediatric Anaesthesia, ISSN 1155-5645, E-ISSN 1460-9592, Vol. 28, nr 1, s. 46-52Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background

    Children often starve for longer than recommended by current preoperative fasting guidelines.

    Aims

    We studied the effects of implementing a more lenient fasting regimen on the duration of clear fluid fasting, as well as the incidence of extended fasting in children.

    Methods

    Preoperative duration of clear fluid fasting was recorded for patients scheduled for procedures in a unit applying the standard 6-4-2 fasting regimen. This group was compared with a cohort in the same unit 1year after transitioning to a 6-4-0 fasting regimen. The latter includes no limitations on clear fluid intake until the child is called to theater. A third cohort from a unit in which the 6-4-0 fasting regimen has been implemented for over a decade was also studied for comparison.

    Results

    Patients fasting according to the 6-4-2 fasting regimen (n=66) had a median fasting time for clear fluids of 4.0h and a 33.3% incidence of fasting more than 6h. After transitioning to the 6-4-0 fasting regimen (n=64), median duration of fasting for clear fluids decreased to 1.0h, and the incidence of fasting more than 6h decreased to 6.3%. In the second unit (n=73), median fasting time was 2.2h and the proportion of patients fasting more than 6h was 21.9%.

    Conclusion

    The introduction and implementation of the 6-4-0 fasting regimen reduces median fluid fasting duration and the number of children subjected to extended fasting.

    Low incidence of pulmonary aspiration in children allowed intake of clear fluids until called to the operating suite2015Inngår i: Pediatric Anaesthesia, ISSN 1155-5645, E-ISSN 1460-9592, Vol. 25, nr 8, s. 770-777Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: International guidelines recommend 2 h of clear fluid fasting prior to general anesthesia. The pediatric anesthesia unit of Uppsala University Hospital has been implementing a more liberal fasting regime for more than a decade; thus, children scheduled for elective procedures are allowed to drink clear fluids until called to the operating suite.

    AIM: To determine the incidence of perioperative pulmonary aspiration in pediatric patients allowed unlimited intake of clear fluids prior to general anesthesia.

    METHOD: Elective pediatric procedures between January 2008 and December 2013 were examined retrospectively by reviewing anesthesia charts and discharge notes in the electronic medical record system. All notes from the care event and available chest x-rays were examined for cases showing vomiting, regurgitation, and/or aspiration. Pulmonary aspiration was defined as radiological findings consistent with aspiration and/or postoperative symptoms of respiratory distress after vomiting during anesthesia.

    RESULTS: Of the 10 015 pediatric anesthetics included, aspiration occurred in three (0.03% or 3 in 10 000) cases. No case required cancellation of the surgical procedure, intensive care or ventilation support, and no deaths attributable to aspiration were found. Pulmonary aspiration was suspected, but not confirmed by radiology or continuing symptoms, in an additional 14 cases.

    CONCLUSION: Shortened fasting times may improve the perioperative experience for parents and children with a low risk of aspiration.

    The clinical expression of asthma in schoolchildren has changed between 1996 and 20062010Inngår i: Pediatric Allergy and Immunology, ISSN 0905-6157, E-ISSN 1399-3038, Vol. 21, nr 5, s. 859-866Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Several studies have reported diverging trends in the prevalence of asthma and wheeze. The aim of this study was to investigate the clinical expression of childhood asthma in 1996 and 2006 by studying asthma morbidity, treatment, and environmental exposures in school children with physician-diagnosed asthma and wheeze, respectively. All children enrolled in first or second grade (7-8 yr-old) in three municipalities in northern Sweden were invited to a questionnaire study in 1996 and 2006, respectively. In 1996, 3430 (97%) participated; and in 2006, 2585 (96%) participated. The same parental completed questionnaire, including the ISAAC questions, was used in both surveys. Physician-diagnosed asthma was reported at 5.7% in 1996 and 7.4% in 2006. A significantly greater proportion of children with asthma were using inhaled corticosteroids (ICS) in 2006, 67% vs. 55% in 1996. This increase was parallel to a major decrease in severe asthma symptoms such as disturbed sleep because of wheeze (49% vs. 38%) and troublesome asthma (21% vs. 11%). The prevalence of current wheeze among the asthmatics decreased significantly; however, this was seen only among children not using ICS. Parental smoking decreased significantly as did the proportion living in damp buildings. In conclusion, although asthma remains a major public health issue in school age children, children with asthma had less respiratory symptoms and a better asthma control in 2006 compared to 1996. This parallels with an increase in treatment with ICS, more beneficial environmental conditions, and an increased diagnostic intensity resulting in a larger proportion of children with mild symptoms being diagnosed as having asthma.

    Remission and Persistence of Asthma Followed From 7 to 19 Years of Age2013Inngår i: Pediatrics, ISSN 0031-4005, E-ISSN 1098-4275, Vol. 132, nr 2, s. E435-E442Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND AND OBJECTIVE: To date, a limited number of population-based studies have prospectively evaluated the remission of childhood asthma. This work was intended to study the remission and persistence of childhood asthma and related factors. METHODS: In 1996, a questionnaire was distributed to the parents of all children aged 7 to 8 years in 3 municipalities in northern Sweden, and 3430 (97%) participated. After a validation study, 248 children were identified as having asthma; these children were reassessed annually until age 19 years when 205 (83%) remained. During the follow-up period lung function, bronchial challenge testing, and skin prick tests were performed. Remission was defined as no use of asthma medication and no wheeze during the past 12 months as reported at endpoint and in the 2 annual surveys preceding endpoint (ie, for >= 3 years). RESULTS: At age 19 years, 21% were in remission, 38% had periodic asthma, and 41% persistent asthma. Remission was more common among boys. Sensitization to furred animals and a more severe asthma (asthma score >= 2) at age 7 to 8 years were both inversely associated with remission, odds ratio 0.14 (95% confidence interval 0.04-0.55) and 0.19 (0.07-0.54), respectively. Among children with these 2 characteristics, 82% had persistent asthma during adolescence. Asthma heredity, damp housing, rural living, and smoking were not associated with remission. CONCLUSIONS: The probability of remission of childhood asthma from age 7- to 8-years to age 19 years was largely determined by sensitization status, particularly sensitization to animals, asthma severity, and female gender, factors all inversely related to remission.

    Effects of Delayed versus Early Cord Clamping on Healthy Term Infants2013Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    The aim of this thesis was to study maternal and infant effects of delayed cord clamping (≥180 seconds, DCC) compared to early (≤10 seconds, ECC) in a randomised controlled trial. Practice and guidelines regarding when to clamp the cord vary globally, and different meta-analyses have shown contradictory conclusions on benefits and disadvantages of DCC and ECC.

    The study population consisted of 382 term infants born after normal pregnancies and randomised to DCC or ECC after birth. The primary objective was iron stores and iron deficiency at 4 months of age, but the thesis was designed to investigate a wide range of suggested effects associated with cord clamping.

    Paper I showed that DCC was associated with improved iron stores at 4 months (45% higher ferritin) and that the incidence of iron deficiency was reduced from 5.7% to 0.6%. Neonatal anaemia at 2-3 days was less frequent in the DCC group, 1.2% vs. 6.3%. There were no differences between the groups in respiratory symptoms, polycythaemia, or hyperbilirubinaemia.

    In paper II we demonstrated that DCC versus ECC was not associated with higher risk for maternal post partum haemorrhage and rendered a comparable ratio of valid umbilical artery blood gas samples.

    In paper III, the Ages and Stages Questionnaire was used to assess neurodevelopment at 4 months. The total scores did not differ, but the DCC group had a higher score in the problem-solving domain and a lower score in the personal-social domain. Immunoglobulin G level was 0.7 g/L higher in the DCC group at 2–3 days, but did not differ at 4 months. Symptoms of infection up to 4 months were comparable between groups.

    Finally, in paper IV, iron stores and neurodevelopment were similar between groups at 12 months. Gender specific outcome on neurodevelopment at 12 months was discovered, implying positive effects from DCC on boys and negative on girls.

    We conclude that delaying umbilical cord clamping for 180 seconds is safe and associated with a significantly reduced risk for iron deficiency at 4 months, which may have neurodevelopmental effects at a later age.
