    Effect of gene, environment and maternal depressive symptoms on pre-adolescence behavior problems: a longitudinal study2013In: Child and Adolescent Psychiatry and Mental Health, ISSN 1753-2000, E-ISSN 1753-2000, Vol. 7, article id 10Article in journal (Refereed)
    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 effects2016In: BMC Pediatrics, ISSN 1471-2431, E-ISSN 1471-2431, Vol. 16, article id 76Article in journal (Refereed)
    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 Trial2005Doctoral thesis, comprehensive summary (Other academic)
    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.

    Abstract [en]

    Aim:      This article describes a locally developed, two-tiered program of counseling training, aimed at supporting mothers of term, low birth weight infants to exclusively breastfeed from birth to 6 months. Methods:      An invitation to attend a mother–child health seminar was sent to 13 health centers in Metropolitan Manila. Level One training consisted of a three-day seminar on postpartum mother–child care conducted by the health staff of the Philippine General Hospital. Level Two of the training, conducted by a certified breastfeeding counselor, consisted of a 40-hour instructional program which used interactive didactics and practical skill workshops which taught the counselors how to prevent and manage breastfeeding problems. Result:      Thirty of 37 (81%) women passed Level One training. Fourteen of these 30 women (46.7%) decided to proceed to Level Two training. Eight of the 14 women who had the longest breastfeeding experience were chosen to undergo the Level Two training. All eight women completed the training. Six of the eight (75%) had satisfactory post-training assessment; the remaining two were re-trained and were subsequently assessed to be fit for counseling work. An assessment of post-training competencies showed that counseling knowledge and skills were improved by the training. Further, the intervention demonstrated a 56.6% exclusive breastfeeding rate at six months compared to the national prevalence rate of 1.4%. Conclusion:      This training program has increased breastfeeding counseling knowledge as established by increased correct breastfeeding information and appropriate counseling skills observed after the women completed the training.

    School performance after preterm birth2015In: Epidemiology, ISSN 1044-3983, E-ISSN 1531-5487, Vol. 26, no 1, p. 106-111Article in journal (Refereed)
    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.

    Growth hormone dose-dependent pubertal growth: a randomized trial in short children with low growth hormone secretion2014In: Hormone Research in Paediatrics, ISSN 1663-2818, E-ISSN 1663-2826, Vol. 82, no 3, p. 158-170Article in journal (Refereed)
    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 µg/kg/day for ≥1 year. They were randomized to receive 67 µg/kg/day (GH(67)) given as one (GH(67×1); n = 35) or two daily injections (GH(33×2); n = 36), or to remain on a single 33 µg/kg/day dose (GH(33×1); n = 40). Growth was assessed as heightSDSgain for prepubertal, pubertal and total periods, as well as AHSDS versus the population and the midparental height.

    RESULTS: Pubertal heightSDSgain was greater for patients receiving a high dose (GH(67), 0.73) than a low dose (GH(33×1), 0.41, p < 0.05). AHSDS was greater on GH(67) (GH(67×1), -0.84; GH(33×2), -0.83) than GH(33) (-1.25, p < 0.05), and heightSDSgain was greater on GH(67) than GH(33) (2.04 and 1.56, respectively; p < 0.01). All groups reached their target heightSDS.

    CONCLUSION: Pubertal heightSDSgain and AHSDS 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.

    High Blood Pressure in Children with Hydronephrosis2018Doctoral thesis, comprehensive summary (Other academic)
    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.

    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.

    Abstract [en]

    Hydronephrosis is associated with development of salt-sensitive hypertension. Studies suggest that increased sympathetic nerve activity (SNA) and oxidative stress play important roles in renovascular hypertension. This study aimed to investigate the link between renal SNA and NADPH oxidase (NOX) regulation in the development of hypertension in rats with hydronephrosis. Hydronephrosis was induced by partial unilateral ureteral obstruction (PUUO) in young rats. Sham surgery or renal denervation was performed at the same time. Blood pressure was measured during normal, high and low salt diets. Renal excretion pattern, NOX activity and expression, as well as components of RAAS were characterized. On normal salt diet, PUUO rats had elevated blood pressure compared with controls (115±3 vs 87±1 mmHg), and displayed increased urine production and lower urine osmolality. Blood pressure change in response to salt loading (salt-sensitivity) was more pronounced in the PUUO group compared with controls (15±2 vs 5±1mmHg). Renal denervation in PUUO rats attenuated hypertension (97±3mmHg) and salt-sensitivity (5±1mmHg), and normalized renal excretion pattern, whereas the degree of renal fibrosis and inflammation was not changed. NOX activity and expression, as well as renin and AT1A receptor expression, were increased in renal cortex from PUUO rats, and normalized by denervation. Plasma sodium and potassium levels were elevated in PUUO rats and normalized after renal denervation. Denervation in PUUO rats was also associated with reduced NOX expression, superoxide production and fibrosis in the heart. This study emphasizes a link between renal nerves, NOX function, and development of hypertension.

    Abstract [en]

    Objective Recent clinical studies have suggested an increased risk of elevated arterial pressure in patients with hydronephrosis. Animals with experimentally induced hydronephrosis develop hypertension, which is correlated to the degree of obstruction and increased oxidative stress. In this prospective study we investigated changes in arterial pressure, oxidative stress, and nitric oxide (NO) homeostasis following correction of hydronephrosis.

    Methods Ambulatory arterial pressure (24 h) was monitored in pediatric patients with hydronephrosis (n = 15) before and after surgical correction, and the measurements were compared with arterial pressure measurements in two control groups, i.e. healthy controls (n = 8) and operated controls (n = 8). Markers of oxidative stress and NO homeostasis were analyzed in matched urine and plasma samples.

    Results The preoperative mean arterial pressure was significantly higher in hydronephrotic patients [83 mmHg; 95% confidence interval (CI) 80–88 mmHg] than in healthy controls (74 mmHg; 95% CI 68–80 mmHg; p < 0.05), and surgical correction of ureteral obstruction reduced arterial pressure (76 mmHg; 95% CI 74–79 mmHg; p < 0.05). Markers of oxidative stress (i.e., 11- dehydroTXB2, PGF2α, 8-iso-PGF2α, 8,12-iso-iPF2α-VI) were significantly increased (p < 0.05) in patients with hydronephrosis compared with both control groups, and these were reduced following surgery (p < 0.05). Interestingly, there was a trend for increased NO synthase activity and signaling in hydronephrosis, which may indicate compensatory mechanism(s).

    Conclusion This study demonstrates increased arterial pressure and oxidative stress in children with hydronephrosis compared with healthy controls, which can be restored to normal levels by surgical correction of the obstruction. Once reference data on ambulatory blood pressure in this young age group become available, we hope cut-off values can be defined for deciding whether or not to correct hydronephrosis surgically.

    Surgical treatment reduces blood pressure in children with unilateral congenital hydronephrosis2015In: Journal of Pediatric Urology, ISSN 1477-5131, E-ISSN 1873-4898, Vol. 11, no 2, p. 91.e1-91.e6Article in journal (Refereed)
    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.

    Early Detection and Treatment for Children: Experiences and outcome of implementation at a pediatric hospital2018Doctoral thesis, comprehensive summary (Other academic)
    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.

    Abstract [en]

    Purpose: The aim of this study was to describe healthcare professionals' experience of caring for acutely, severely ill children in hospital in Sweden.

    Design and Methods: Five focus group interviews were conducted with nurses, nurse assistants and physicians comprising a total of 20 participants. Data were analyzed using qualitative content analysis.

    Results: An overall theme emerged that describes healthcare professionals' experiences as: "being in a multifaceted area of tension with paradoxical elements". The theme is based on three categories: proficiency of the individuals and the team is the fundamental base; interactions are crucial in an area of tension; and wellbeing of the individual is a balance of contradictory emotions. With maintained focus on the ill child, proficiency is the fundamental base, interactions are crucial, and moreover contradictory emotions are described.

    Conclusions: The interplay based on proficiency may influence the assessments and treatments of acutely, severely ill children.

    Practice Implications: Recognizing the multifaceted area of tension with paradoxical elements, practical teamwork exercises, a structured approach, and assessment tools could be a possible way to develop interprofessional team collaboration to improve the care of acutely, severely ill children in order to increase patient safety.

    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.

    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.

    Introducing the 6-4-0 fasting regimen and the incidence of prolonged preoperative fasting in children2018In: Pediatric Anaesthesia, ISSN 1155-5645, E-ISSN 1460-9592, Vol. 28, no 1, p. 46-52Article in journal (Refereed)
    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 suite2015In: Pediatric Anaesthesia, ISSN 1155-5645, E-ISSN 1460-9592, Vol. 25, no 8, p. 770-777Article in journal (Refereed)
    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.

    Effects of Delayed versus Early Cord Clamping on Healthy Term Infants2013Doctoral thesis, comprehensive summary (Other academic)
    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.

    Abstract [en]

    Objective: To investigate the effects of delayed umbilical cord clamping, compared with early clamping, on infant iron status at 4 months of age in a European setting.

    Design: Randomised controlled trial.

    Setting: Swedish county hospital.

    Participants: 400 full term infants born after a low risk pregnancy.

    Intervention: Infants were randomised to delayed umbilical cord clamping (>= 180 seconds after delivery) or early clamping (<= 10 seconds after delivery).

    Main outcome measures: Haemoglobin and iron status at 4 months of age with the power estimate based on serum ferritin levels. Secondary outcomes included neonatal anaemia, early respiratory symptoms, polycythaemia, and need for phototherapy.

    Results: At 4 months of age, infants showed no significant differences in haemoglobin concentration between the groups, but infants subjected to delayed cord clamping had 45% (95% confidence interval 23% to 71%) higher mean ferritin concentration (117 mu g/L v 81 mu g/L, P<0.001) and a lower prevalence of iron deficiency (1 (0.6%) v 10 (5.7%), P=0.01, relative risk reduction 0.90; number needed to treat=20 (17 to 67)). As for secondary outcomes, the delayed cord clamping group had lower prevalence of neonatal anaemia at 2 days of age (2 (1.2%) v 10 (6.3%), P=0.02, relative risk reduction 0.80, number needed to treat 20 (15 to 111)). There were no significant differences between groups in postnatal respiratory symptoms, polycythaemia, or hyperbilirubinaemia requiring phototherapy.

    Conclusions: Delayed cord clamping, compared with early clamping, resulted in improved iron status and reduced prevalence of iron deficiency at 4 months of age, and reduced prevalence of neonatal anaemia, without demonstrable adverse effects. As iron deficiency in infants even without anaemia has been associated with impaired development, delayed cord clamping seems to benefit full term infants even in regions with a relatively low prevalence of iron deficiency anaemia.

    Abstract [en]

    Objective

    To investigate the effect of delayed cord clamping (DCC) compared with early cord clamping (ECC) on maternal postpartum hemorrhage (PPH) and umbilical cord blood gas sampling.

    Design

    Secondary analysis of a parallel-group, single-center, randomized controlled trial.

    Setting

    Swedish county hospital.

    Population

    382 term deliveries after a low-risk pregnancy.

    Methods

    Deliveries were randomized to DCC (≥180 seconds, n = 193) or ECC (≤10 seconds, n = 189). Maternal blood loss was estimated by the midwife. Samples for blood gas analysis were taken from one umbilical artery and the umbilical vein, from the pulsating unclamped cord in the DCC group and from the double-clamped cord in the ECC group. Samples were classified as valid when the arterial-venous difference was -0.02 or less for pH and 0.5 kPa or more for pCO2.

    Main outcome measures

    PPH and proportion of valid blood gas samples.

    Results

    The differences between the DCC and ECC groups with regard to PPH (1.2%, p = 0.8) and severe PPH (-2.7%, p = 0.3) were small and non-significant. The proportion of valid blood gas samples was similar between the DCC (67%, n = 130) and ECC (74%, n = 139) groups, with 6% (95% confidence interval: -4%-16%, p = 0.2) fewer valid samples after DCC.

    Conclusions

    Delayed cord clamping, compared with early, did not have a significant effect on maternal postpartum hemorrhage or on the proportion of valid blood gas samples. We conclude that delayed cord clamping is a feasible method from an obstetric perspective.

    Abstract [en]

    AIM:

    To investigate the effect that delayed and early umbilical cord clamping have on neurodevelopment, immunoglobulin G (IgG) and symptoms of infection during the first 4 months of life.

    METHODS:

    Full-term infants (n = 382) were randomised to delayed (≥180 sec) or early cord clamping (≤10 sec). The Ages and Stages Questionnaire (ASQ) was used to assess neurodevelopment at 4 months. Immunoglobulin G was measured at birth, 2-3 days and 4 months. Parents recorded any symptoms indicating infection during the first 4 months of life.

    RESULTS:

    The total scores from the ASQ did not differ between groups. However, the delayed cord clamping (DCC) group had a higher mean (SD) score in the problem-solving domain [55.3 (7.2) vs. 53.5 (8.2), p = 0.03] at 4 months and a lower mean (SD) score in the personal-social domain [49.5 (9.3) vs. 51.8 (8.1), p = 0.01]. The IgG level was higher in the DCC group at 2-3 days (11.7 vs. 11.0 g/L, p = 0.004), but did not differ between the groups at 4 months. Symptoms of infection were comparable between the groups.

    CONCLUSION:

    Delayed cord clamping did not affect overall neurodevelopment or symptoms of infection up to 4 months of age, but may have an impact on specific neurodevelopmental domains.

    Abstract [en]

    Objectives: To investigate effects of delayed umbilical cord clamping, as compared to early, on iron status and infant development at 12 months of age.

    Study design: Term infants (n = 382) were randomly assigned to delayed (≥180 sec) or early (≤10 sec) umbilical cord clamping. Follow up at 12 months of age included evaluation of iron status (ferritin, transferrin saturation, transferrin receptor, reticulocyte hemoglobin equivalent and mean cell volume) and parental assessment of neurodevelopment by the Ages and Stages Questionnaire.

    Results: At 12 months 347 infants were assessed. The two randomization groups did not differ in iron status or in neurodevelopment; 13 had iron deficiency and only one infant had iron deficiency anemia. Predictors of ferritin levels were infant sex and ferritin in umbilical cord blood. Predictors of ASQ were infant sex and breastfeeding within one hour after birth. For both outcomes, being a boy was associated with lower results. Interaction analysis showed that delayed cord clamping was associated with a 5 points higher ASQ score among boys, but a 12 points lower score in girls, out of a maximum of 300 points.

    Conclusions: Delayed cord clamping increases neonatal hemoglobin levels and improves iron status at four months of age, but does not affect ferritin levels or neurodevelopment assessed by ASQ in a selected population of healthy term born infants. However, minor effects on neurodevelopment may not be possible to demonstrate with the size of the study population and the chosen method for assessment. The current data indicate that effects of delayed cord clamping may differ according to infant sex and that boys may benefit more from delayed cord clamping than girls.

    Effect of Delayed vs Early Umbilical Cord Clamping on Iron Status and Neurodevelopment at Age 12 Months A Randomized Clinical Trial2014In: JAMA PEDIATR, ISSN 2168-6203, Vol. 168, no 6, p. 547-554Article in journal (Refereed)
    Abstract [en]

    IMPORTANCE Prevention of iron deficiency in infancy may promote neurodevelopment. Delayed cord clamping (DCC) can prevent iron deficiency during the first 6 months of life. However, no data are available on long-term effects on infant outcomes in relation to time for umbilical cord clamping. OBJECTIVE To investigate effects of DCC, as compared with early cord clamping (ECC), on infant iron status and neurodevelopment at age 12 months in a European setting. DESIGN, SETTING, AND PARTICIPANTS Randomized clinical trial of 382 full-term infants born after a low-risk pregnancy at a Swedish county hospital. Follow-up at 12 months included evaluation of iron status (ferritin level, transferrin saturation, transferrin receptor level, reticulocyte hemoglobin level, and mean cell volume) and parental assessment of neurodevelopment by the Ages and Stages Questionnaire, second edition (ASQ). INTERVENTIONS Infants were randomized to DCC (>= 180 seconds after delivery) or ECC (<= 10 seconds after delivery). MAIN OUTCOMES AND MEASURES The main outcome was iron status at age 12 months; the secondary outcome was ASQ score. RESULTS In total, 347 of 382 infants (90.8%) were assessed. The DCC and ECC groups did not differ in iron status (mean ferritin level, 35.4 vs 33.6 ng/mL, respectively; P =.40) or neurodevelopment (mean ASQ total score, 229.6 vs 233.1, respectively; P =.42) at age 12 months. Predictors of ferritin levels were infant sex and ferritin in umbilical cord blood. Predictors of ASQ score were infant sex and breastfeeding within 1 hour after birth. For both outcomes, being a boy was associated with lower results. Interaction analysis showed that DCC was associated with an ASQ score 5 points higher among boys (mean [SD] score, 229 [43] for DCC vs 224 [39] for ECC) but 12 points lower among girls (mean [SD] score, 230 [39] for DCC vs 242 [36] for ECC), out of a maximum of 300 points (P =.04 for the interaction term). CONCLUSIONS AND RELEVANCE Delayed cord clamping did not affect iron status or neurodevelopment at age 12 months in a selected population of healthy term-born infants. However, it may not be possible to demonstrate minor effects on neurodevelopment with the size of the study population and the chosen method for assessment. The current data indicate that sex may influence the effects on infant development after DCC in different directions. The magnitude and biological reason for this finding remain to be investigated.

    Elective caesarean: does delay in cord clamping for 30 s ensure sufficient iron stores at 4 months of age? A historical cohort control study2016In: BMJ Open, ISSN 2044-6055, E-ISSN 2044-6055, Vol. 6, no 11, article id e012995Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: To compare iron stores in infants born after elective caesarean section (CS) and a 30 s delay of umbilical cord clamping with those born vaginally after early (≤10 s) or delayed (≥180 s) cord clamping.

    DESIGN: Prospective observational study with historical control.

    SETTING: Swedish county hospital.

    POPULATION: 64 infants born after elective CS were compared with a historical control of 166 early clamped and 168 delayed clamped after vaginal birth.

    METHODS: Blood and iron status were measured in blood samples collected at birth, 48-96 hours after birth, 4 and 12 months of age.

    PRIMARY AND SECONDARY OUTCOME MEASURES: Ferritin at 4 months of age was the primary outcome, second outcome measures were other indicators of iron status, and haemoglobin, at 4 and 12 months of age, as well as respiratory distress at 1 and 6 hours after birth.

    RESULTS: At 4 months infants born by elective CS had better iron status than those born vaginally subjected to early cord clamping, shown by higher adjusted mean difference of ferritin concentration (39 µg/L (95% CI 10 to 60)) and mean cell volume (1.8 fL (95% CI 0.6 to 3.0)); and lower levels of transferrin receptors (-0.39 mg/L (95% CI -0.69 to -0.08)). No differences were seen between infants born after elective CS and delayed clamped vaginally born infants at 4 months. No differences were found between groups at 12 months of age.

    CONCLUSIONS: Waiting to clamp the umbilical cord for 30 s after elective CS results in higher iron stores at 4 months of age compared with early cord clamping after vaginal birth, and seems to ensure iron status comparable with those achieved after 180 s delayed cord clamping after vaginal birth.

    Effect of Delayed Cord Clamping on Neurodevelopment at 4 Years of Age A Randomized Clinical Trial2015In: JAMA pediatrics, ISSN 2168-6203, E-ISSN 2168-6211, Vol. 169, no 7, p. 631-638Article in journal (Refereed)
    Abstract [en]

    IMPORTANCE Prevention of iron deficiency in infancy may promote neurodevelopment. Delayuci umbilical cord clamping (CC) prevents iron deficiency at 4 to 6 months of age, but long-term effects after 12 months of age have not been reported. OBJECTIVE To investigate the effects of delayed CC compared with early CC on neurodevelopment at 4 years of age. DESIGN, SETTING, AND PARTICIPANTS Follow-up of a randomized clinical trial conducted from April 16, 2008, through May 21, 2010, at a Swedish county hospital. Children who were included in the original study (n = 382) as full-term infants born after a low-risk pregnancy were invited to return for follow-up at 4 years of age. Wechsler Preschool and Primary Scale of Intelligence (WPPSI-111) and Movement Assessment Battery for Children (Movement ABC) scores (collected between April 18, 2012, and July 5, 2013) were assessed by a blinded psychologist. Between April 11, 2012, and August 13, 2013, parents recorded their child's development using the Ages and Stages Questionnaire, Third Edition (ASQ) and behavior using the Strengths and Difficulties Questionnaire. All data were analyzed by intention to treat. INTERVENTIONS Randomization to delayed CC (>= 180 seconds after delivery) or early CC (<= 10 seconds after delivery). MAIN OUTCOMES AND MEASURES The main outcome was full-scale IQ as assessed by the were development as assessed by the scales from the WPPSI-III and Movement ABC, development as recorded using the ASQ, and behavior using the Strengths and Difficulties Questionnaire. RESULTS We assessed 263 children (68.8%). No differences were found in WPPSI-III scores between groups. Delayed CC improved the adjusted mean differences (AMDs) in the ASQ personal-social (AMD, 2.8; 95% Cl, 0.8-4.7) and fine-motor (AMD, 2.1; 95% Cl, 0.2-4.0) domains and the Strengths and Difficulties Questionnaire prosocial subscale (AMD, 0.5; 95% Cl, >0.0-0.9). Fewer children in the delayed-CC group had results below the cutoff in the ASQ fine-motor domain (11.0% vs 3.7%; P =.02) and the Movement ABC bicycle-trail task (12.9% vs 3.8%; P =.02). Boys who received delayed CC had significantly higher AMDs in the WPPSI-III processing-speed quotient (AMD, 4.2; 95% Cl, 0.8-7.6; P =.02), Movement ABC bicycle-trail task (AMD, 0.8; 95% Cl, 0.1-1.5; P =.03), and fine-motor (AMD, 4.7; 95% Cl, 1.0-8.4; P =.01) and personal-social (AMD, 4.9; 95% Cl, 1.6-8.3; P =.004) domains of the ASQ. CONCLUSIONS AND RELEVANCE Delayed CC compared with early CC improved scores in the fine-motor at 4 years of age, especially in boys, indicating that optimizing the time to CC may affect neurodevelopment in a low-risk population of children born in a high-income country.

    Outcome of laparoscopic versus open gastrostomy in children2015In: Pediatric surgery international (Print), ISSN 0179-0358, E-ISSN 1437-9813, Vol. 31, no 11, p. 1067-1072Article in journal (Refereed)
    Abstract [en]

    Laparoscopic gastrostomy (LAPG) has gained popularity in children. The aim of this study was to compare the outcome of LAPG versus open gastrostomy (OG) in children with focus on complications, operative times and postoperative length of stay. Retrospective study of children who had gastrostomies inserted at our tertiary Pediatric Surgery Center from 2000 until 2013. The indications for a gastrostomy were an anticipated need for enteral support for at least 6 months. Totally 243 children were included in the study, 83 with LAPG and 160 with OG. We found a significant difference in postoperative length of stay, 3 days in the LAPG group versus 4 days in the OG group but no difference in a sub-group analysis from 2010 to 2013 when both techniques were used. There was no difference in median operative time or complications rates. Granuloma was the dominating complication in both groups. These two feeding-access techniques are comparable regarding complications, operative times and postoperative length of stay. The choice of surgical method should be individualized based on the patient's characteristics and the experience of the surgeon. The favorable results with LAPG in adults are not necessarily transferable to children since there are physiological and anatomical differences.

    Improved outcome in neonatal short bowel syndrome using parenteral fish oil in combination With ω-6/9 Lipid Emulsions2012In: JPEN - Journal of Parenteral and Enteral Nutrition, ISSN 0148-6071, E-ISSN 1941-2444, Vol. 36, no 5, p. 587-595Article in journal (Refereed)
    Abstract [en]

    Background:

    Newborn infants with short bowel syndrome (SBS) represent a high risk group of developing intestinal failure-associated liver disease (IFALD) which may be fatal. However, infants have a great capacity for intestinal growth and adaptation if IFALD can be prevented or reversed. A major contributing factor to IFALD may be the soybean oil-based intravenous lipid emulsions used since the introduction of parenteral nutrition (PN) 40 years ago.

    Methods:

    This retrospective study compares the outcome in 20 neonates with SBS treated with parenteral fish oil (Omegaven) in combination with omega-6/9 lipid emulsions (ClinOleic) with the outcome in a historical cohort of 18 patients with SBS who received a soybean oil-based intravenous lipid emulsion (Intralipid).

    Results:

    Median gestational age was 26 weeks in the treatment group and 35.5 weeks in the historical group. All patients were started on PN containing Intralipid that was switched to ClinOleic/Omegaven in the treatment group at a median age of 39 gestational weeks. In the treatment group, direct bilirubin levels were reversed in all 14 survivors with cholestasis (direct bilirubin >50 umol/). Median time to reversal was 2.9 months. Only 2 patients died of liver failure (10%).  In the historical cohort, 6 patients (33%) died of liver failure and only 2 patients showed normalization of bilirubin levels.

    Conclusions:

    Parenteral fish oil in combination with omega-6/9 lipid emulsions was associated with improved outcome in premature neonates with SBS. When used instead of traditional soybean-based emulsions, this mixed lipid emulsion may facilitate intestinal adaptation by increasing the IFALD-free period.

    Resolution of infantile intestinal pseudo-obstruction in a boy2017In: Journal of Osteoporosis and Physical Activity, ISSN 2052-3211, E-ISSN 2213-5766, Vol. 24, p. 28-34Article in journal (Refereed)
    Abstract [en]

    A term boy with spontaneous passage of meconium exhibited episodes of abdominal distension and diarrhea. Due to failure to thrive and suspicion of Hischsprung's disease he was referred to our university hospital at five months of age. Rectal biopsies were normal. Laparotomy revealed dilation of the small bowel and colon without any mechanical obstruction. Full thickness bowel biopsies were taken and a loop ileostomy was constructed. Histopathology revealed fibrosing myopathy, Cajal cell hypertrophy, and neuronal degeneration in both the large and small bowel. The small bowel showed mastocytosis without inflammation. A central venous catheter was placed for vascular access, replaced three times and later switched to a subcutaneous venous port. Catheters were locked after use with vancomycin-heparin and later taurolidine. The individually tailored home parenteral nutrition contained unsaturated fatty acid lipids to reduce cholestasis. Initial insufficient growth was improved after correction of partial parenteral nutrition based on a metabolic balance study. The ileostomy was revised once and finally taken down at 11 years of age following one year without parenteral support. At follow-up at 13 years of age he has episodes of moderate abdominal pain and has entered puberty and reports a high quality of life. (C) 2017 The Authors. Published by Elsevier Inc.

    Objective: The aim of this study was to investigate practice behaviours of Swedish physicians with regard to discussing the impact of cancer treatment on fertility with paediatric oncology patients and their parents, and to identify factors associated with such discussions.

    Methods: A cross-sectional survey study was conducted targeting all physicians in Sweden working in paediatric oncology care settings. Participants responded to a questionnaire measuring practice behaviour, attitudes, barriers, and confidence in knowledge. Multivariable logistic regression was used to determine factors associated with seldom discussing fertility.

    Results: More than half of the physicians routinely talked with their patients/parents about the treatment's potential impact on fertility (male patients: 62%; female patients: 57%; P = 0.570). Factors associated with less frequently discussing fertility with patients/parents were working at a non-university hospital (male patients: OR 11.49, CI 1.98-66.67; female patients: OR 33.18, CI 4.06-271.07), concerns that the topic would cause worry (male patients: OR 8.23, CI 1.48-45.89; female patients: OR 12.38, CI 1.90-80.70), and perceiving the parents as anxious (male patients: OR 7.18, CI 1.20-42.85; female patients: OR 11.65, CI 1.32-103.17).

    Conclusions: Based on our findings, we recommend structured training in how to communicate about fertility issues in stressful situations, which in turn might increase fertility-related discussions in paediatric oncology.

    Gut microbiota-host interactions and juvenile idiopathic arthritis2016In: Pediatric Rheumatology, ISSN 1546-0096, E-ISSN 1546-0096, Vol. 14, article id 44Article, review/survey (Refereed)
    Abstract [en]

    Background: Juvenile idiopathic arthritis is the most common form of chronic arthritis in children. There is mounting evidence that the microbiota may influence the disease. Main body: Recent observations in several systemic inflammatory diseases including JIA have indicated that abnormalities in the contents of the microbiota may be factors in disease pathogenesis, while other studies in turn have shown that environmental factors impacting the composition of the microbiota, such as delivery mode and early exposure to antibiotics, affect the risk of chronic inflammatory diseases including JIA. Microbial alterations may predispose to JIA through a variety of mechanisms, including impaired immunologic development, alterations in the balances of pro- versus anti-inflammatory bacteria, and low-grade mucosal inflammation. Additional confirmatory studies of microbiota aberrations and their risk factors are needed, as well as additional mechanistic studies linking these alterations to the disease itself. Conclusions: The microbiota may influence the risk of JIA and other systemic inflammatory conditions through a variety of mechanisms. Additional research is required to improve our understanding of the links between the microbiota and arthritis, and the treatment implications thereof.

    The standardization of terminology of lower urinary tract function in children and adolescents: Update report from the standardization committee of the International Children's Continence Society2016In: Neurourology and Urodynamics, ISSN 0733-2467, E-ISSN 1520-6777, Vol. 35, no 4, p. 471-481Article in journal (Refereed)
    Abstract [en]

    AimThe impact of the original International Children's Continence Society (ICCS) terminology document on lower urinary tract (LUT) function resulted in the global establishment of uniformity and clarity in the characterization of LUT function and dysfunction in children across multiple healthcare disciplines. The present document serves as a stand-alone terminology update reflecting refinement and current advancement of knowledge on pediatric LUT function. MethodsA variety of worldwide experts from multiple disciplines within the ICCS leadership who care for children with LUT dysfunction were assembled as part of the standardization committee. A critical review of the previous ICCS terminology document and the current literature was performed. Additionally, contributions and feedback from the multidisciplinary ICCS membership were solicited. ResultsFollowing a review of the literature over the last 7 years, the ICCS experts assembled a new terminology document reflecting current understanding of bladder function and LUT dysfunction in children using the resources from the literature review, expert opinion and ICCS member feedback. ConclusionsThe present ICCS terminology document provides a current and consensus update to the evolving terminology and understanding of LUT function in children.

    Field Evaluation of a High Throughput Loop Mediated Isothermal Amplification Test for the Detection of Asymptomatic Plasmodium Infections in Zanzibar2017In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 12, no 1, article id e0169037Article in journal (Refereed)
    Abstract [en]

    Background New field applicable diagnostic tools are needed for highly sensitive detection of residual malaria infections in pre-elimination settings. Field performance of a high throughput DNA extraction system for loop mediated isothermal amplification (HTP-LAMP) was therefore evaluated for detecting malaria parasites among asymptomatic individuals in Zanzibar. Methods HTP-LAMP performance was evaluated against real-time PCR on 3008 paired blood samples collected on filter papers in a community-based survey in 2015. Results The PCR and HTP-LAMP determined malaria prevalences were 1.6% (95% CI 1.3-2.4) and 0.7% (95% CI 0.4-1.1), respectively. The sensitivity of HTP-LAMP compared to PCR was 40.8% (CI95% 27.0-55.8) and the specificity was 99.9% (CI95% 99.8-100). For the PCR positive samples, there was no statistically significant difference between the geometric mean parasite densities among the HTP-LAMP positive (2.5 p/mu L, range 0.2-770) and HTP-LAMP negative (1.4 p/mu L, range 0.1-7) samples (p = 0.088). Two lab technicians analysed up to 282 samples per day and the HTP-LAMP method was experienced as user friendly. Conclusions Although field applicable, this high throughput format of LAMP as used here was not sensitive enough to be recommended for detection of asymptomatic low-density infections in areas like Zanzibar, approaching malaria elimination.

    A Novel Mutation in DMD (c.10797+5G > A) Causes Becker Muscular Dystrophy Associated with Intellectual Disability2016In: Journal of Developmental and Behavioral Pediatrics, ISSN 0196-206X, E-ISSN 1536-7312, Vol. 37, no 3, p. 239-244Article in journal (Refereed)
    Abstract [en]

    Background: Severe intellectual disability has been reported in a subgroup of patients with Duchenne muscular dystrophy but is not typically associated with Becker muscular dystrophy. Patient: The authors report a 13-year-old boy, with severe intellectual disability (Wechsler Intelligence Scales for Children-IV, Full Scale IQ < 0.1 percentile), attention-deficit hyperactivity disorder, and mild muscle weakness. He had elevated serum creatine kinase and dystrophic changes on muscle biopsy. Dystrophin immunohistochemistry revealed decreased staining with the C-terminal and mid-rod antibodies and essentially absent staining of the N-terminal immunostain. Sequencing of muscle mRNA revealed aberrant splicing due to a c.10797+5G > A mutation in DMD. Conclusion: Dystrophinopathy may be associated with predominantly cognitive impairment and neurobehavioral disorder, and should be considered in the differential diagnosis of unexplained cognitive or psychiatric disturbance in males.

    First-time events between parents and preterm infants are affected by the designs and routines of neonatal intensive care units2014In: Acta Paediatrica, ISSN 0803-5253, E-ISSN 1651-2227, Vol. 103, no 10, p. 1045-1052Article in journal (Refereed)
    Abstract [en]

    AIM:

    Early parental bonding with preterm babies is particularly important, and the aim of our study was to explore when parents experienced what they regarded as important events for the first time while their infant was in the neonatal intensive care unit (NICU).

    METHODS:

    The study was part of a longitudinal project on Kangaroo Mother Care at two Swedish university hospitals. The parents of 81 infants completed questionnaires during their infants' hospital stay.

    RESULTS:

    Most parents saw and touched their infants immediately after birth, but only a few could hold them skin to skin or swaddle them. Other important events identified by parents included the first time they performed care giving activities and did so independently, interaction and closeness with the infant, signs of the infant's recovery and integration into the family. The timing of the events depended on the physical design of the NICU, whether parents' could stay with their infant round-the-clock and when they were allowed to provide care under supervision and on their own.

    CONCLUSION:

    The design and routines of the NICU dictated when parents first interacted with their infants. Clinical guidelines that facilitate early contact with preterm babies can help parents to make the transition to their parental role.

    Abstract [en]

    Background: Children and adolescents with autism spectrum disorder (ASD) or attention-deficit/hyperactivity disorder (ADHD) are more likely to be surrounded by different risk factors. In order to work preventively with decreasing ADHD and ASD symptoms, there is a need of more knowledge concerning risk factors. Objective: This study aimed to investigate school, health, lifestyle and social interactions association with autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) among schoolchildren aged 6-17 years. Methods: Data for 18,416 children and adolescents aged 6-17 years in the county of Varmland, Sweden, from the school year 2012/2013 and 2013/2014 were obtained from the Student Health Database, which includes information on health examinations by school nurses and self-reported information of mental and physical health, social relations, physical activity, and school conditions. Results: Of all participants, 2.4% reported only ADHD and 1.6% reported only ASD. The results confirmed that ADHD or ASD was significantly associated with worse school experiences, lower socioeconomic status, less physical activity, more substance use, weaker social network and more impairments than those without ADHD or ASD. Conclusions: Knowledge of risk or protective factors during school years is needed to develop interventions to reduce symptoms of neurodevelopmental disorders in children and adolescents.

    Risks of Malignant and Non-Malignant Tumours in Tall Women Treated with High-Dose Oestrogen during Adolescence2014In: Hormone Research in Paediatrics, ISSN 1663-2818, E-ISSN 1663-2826, Vol. 82, no 2, p. 89-96Article in journal (Refereed)
    Abstract [en]

    Background/Aim: High-dose oestrogen treatment has been used to reduce growth in tall adolescent girls. The long-term safety with regard to cancer has not been clarified. Our aim was to study if this growth reduction therapy affects cancer risk later in life. Methods: A cohort study of 369 (172 treated, 197 untreated) Swedish women who in 1973-1993 were assessed for tall adolescent stature was designed. Data were collected from university hospital records, patient questionnaires, and the Swedish Cancer Register. Results: Risks are presented as odds ratios (ORs) with 95% confidence intervals comparing treated to untreated subjects. In treated subjects, the overall OR for having a tumour (malignant or nonmalignant) was 1.7 (0.8-3.8). The ORs were 2.3 (0.4-12.8) for breast tumours, 0.8 (0.2-2.6) for gynaecological tumours, and 6.1 (1.04-infinity) for melanoma. When limiting to malignant tumours, the crude ORs were of similar magnitude. Conclusion: The OR for any melanoma was higher in treated than in untreated women, suggesting an increased risk of melanoma associated with high-dose oestrogen treatment during adolescence. Although the risk estimates were increased for overall tumours, breast tumours, malignant gynaecological tumours, and malignant melanoma, these associations were not statistically significant. Our results need to be verified in a larger cohort. (C) 2014 S. Karger AG, Basel

    Enterovirus Infections of β-Cells: A Mechanism of Induction of Type 1 Diabetes?2005Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The process of β-cell destruction that leads to type 1 diabetes (T1D) is incompletely understood and it is believed to be a result of both genetic and environmental factors. Enterovirus (EV) infections of the β-cells have been proposed to be involved, however, the effects of EV infections on human β-cells have been little investigated. This thesis summarises studies of three different Coxsackie B4 virus strains that have previously been shown to infect human islets. The effects of infections with these EV were studied in vitro in human islets and in a rat insulin-producing cell line. In addition, a pilot study was performed on isolated human islets to investigate the ability to treat such infections with an antiviral compound.

    It was found that one of the virus strains replicated in human β-cells without affecting their main function for at least seven days, which in vivo may increase a virus’s ability to persist in islets.

    Nitric oxide was induced by synthetic dsRNA, poly(IC), but not by viral dsRNA in rat insulinoma cells in the presence of IFN-γ, suggesting that this mediator is not induced by EV infection in β-cells and that poly(IC) does not mimic an EV infection in this respect.

    All three virus strains were able to induce production of the T-cell chemoattractant interferon-γ-inducible protein 10 (IP-10) during infection of human islets, suggesting that an EV infection of the islets might trigger insulitis in vivo.

    Antiviral treatment was feasible in human islets, but one strain was resistant to the antiviral compound used in this study.

    To conclude, a potential mechanism is suggested for the involvement of EV infections in T1D. If EV infections induce IP-10 production in human islet cells in vivo, they might recruit immune cells to the islets. Together with viral persistence and/or virus-induced β-cell damage, this might trigger further immune-mediated β-cell destruction in vivo.

    Abstract [en]

    The aim of the present investigation was to study the effect of infection of human pancreatic islet cells with a strain (VD2921) of Coxsackie B virus serotype 4 capable of establishing persistent infection in these cells, as well as to sequence the strain, to study the determinants of virulence and persistence. Groups of islets were infected and assessments of proinsulin, insulin content, and virus replication were made. Insulin release in response to high glucose was measured. Infected and control islets displayed a strong insulin response to high glucose 3-4 days as well as 7-8 days post-infection (dpi). At 11-17 dpi, the infected islets did not respond at all to high glucose, and the response of the control islets was at this late time point somewhat reduced. The insulin and proinsulin content of the infected islets did not differ significantly from that of the control islets. TCID(50) titrations showed that the VD2921 strain replicated in the islet cells during the whole study. Electron microscopic examination of infected islets did not reveal any virus-induced changes of cell morphology compared with the controls, although higher magnifications of the infected beta-cells showed virus-like particles in the cytoplasm. These results show that certain strains of Coxsackievirus B-4 in vitro can establish a persistent infection that might mimic, the more gradual loss of beta-cell function seen during the clinical course of autoimmune diabetes. The ability of this Coxsackievirus B-4 strain to establish a persistent infection might be due to substitution of 11 amino acids located at the surface of the structural protein VP1, adjacent to the predicted receptor binding canyon of the virus.

    Abstract [en]

    Enterovirus infections of the pancreatic islets are believed to trigger or precipitate the near total destruction of β-cells that constitutes type 1 diabetes (T1D). This study investigated the ability of an anti-picornaviral compound, pleconaril, to block the replication of two β-cell tropic Coxsackie B4 virus (CBV-4) strains in isolated human islets. The two strains, VD2921 and V89 4557, with demonstrated abilities to cause non-lytic persistence or lytic infection, respectively, in islets, represented two different potential mechanisms behind virus-induced T1D. The virus replication in the islets was studied with and without addition of pleconaril. In addition, islet morphology was studied every day. To test the effects of pleconaril and/or DMSO on the β-cells’ insulin secretion, glucose perifusions were performed on treated and untreated islets. Virus titrations showed a clear reduction of the replication of both strains after pleconaril treatment. The VD2921 strain was inhibited to undetectable levels. The V89 4557 strain, however, showed an initial reduction of titers but virus titers then increased despite the addition of a second dose of pleconaril. This incomplete inhibition of viral replication suggested the existence of a resistant subtype within this strain. Pleconaril treatment reduced the β-cells’ insulin secretion in response to glucose stimulation in some experiments and induced slight morphological changes to the islets compared to untreated controls. In summary, pleconaril reduced the replication of the two β-cell tropic CBV-4 strains in human islets. However, genetic differences between these strains influenced the effectiveness of pleconaril treatment. This stresses the importance of using multiple viral strains in antiviral tests.

    Mental health in Swedish children living in joint physical custody and their parents' life satisfaction: A cross-sectional study2014In: Scandinavian Journal of Psychology, ISSN 0036-5564, E-ISSN 1467-9450, Vol. 55, no 5, p. 433-439Article in journal (Refereed)
    Abstract [en]

    This study compared the psychological symptoms of 129 children in joint physical custody with children in single care and nuclear families, using a nationally representative 2011 survey of 1,297 Swedish children aged between four and 18 years. The outcome measure was the Strengths and Difficulties Questionnaire (SDQ) and its association with three dimensions of parental life satisfaction was investigated. Linear regression analyses showed higher SDQ-scores for children in joint physical custody (B=1.4, p<0.001) and single care (B=2.2, p<0.001) than in nuclear families, after adjustment for socio-demographic variables. The estimates decreased to 1.1 and 1.3, respectively, after being adjusted for parental life satisfaction (p<0.01). Our findings confirm previous research that showed lower symptom scores for children in nuclear families than children in single care and joint physical custody. Parental life satisfaction should be investigated further as a possible explanation of differences in symptom load between children in different living arrangements.

    Anti-inflammatory effect of exclusive enteral nutrition in patients with juvenile idiopathic arthritis2016In: Clinical and Experimental Rheumatology, ISSN 0392-856X, E-ISSN 1593-098X, Vol. 34, no 5, p. 941-945Article in journal (Refereed)
    Abstract [en]

    Objective There is extensive evidence for an influence of gut microbiota on the immune system, which has consequences for inflammatory diseases. Exclusive enteral nutrition (EEN), which may change the gut microbiota, is an effective anti-inflammatory treatment for Crohn's disease in children. We wanted to explore the immediate anti-inflammatory effect of EEN in children with juvenile idiopathic arthritis (JIA). Methods Thirteen patients with JIA (7-17 years of age), in a disease flare-up, were included in the study. Six children dropped out within 1.5-2.0 weeks of treatment, and seven patients continued, constituting the study cohort. EEN was given for three to eight weeks, with clinical and laboratory status assessed before and after treatment periods. In addition to conventional laboratory tests, 92 inflammatory proteins were analysed with a multiplex system (Proseek Multiplex Inflammation I, Olink Bioscience). Results EEN had a significant anti-inflammatory effect on active joints (p=0.031), JADAS27 (p=0.016) and morning stiffness (p=0.031). In the multiplex analysis of inflammatory proteins, MMP-1 (matrix metalloproteinase), involved in the degradation of collagens in chondrocytes, decreased significantly (p=0.047), as did MCP-4 (p=0.031) and 4E-BP1 (p=0.031). Conclusion Exclusive enteral nutrition for three to eight weeks had anti-inflammatory effect in all children with JIA that continued with EEN for more than two weeks. The study is only exploratory but the result supports an immunologically important role for the intestinal canal in these patients.

    Anti-type II collagen antibodies, anti-CCP, IgA RF and IgM RF are associated with joint damage, assessed eight years after onset of juvenile idiopathic arthritis (JIA)2014In: Pediatric Rheumatology, ISSN 1546-0096, E-ISSN 1546-0096, Vol. 12, p. 22-Article in journal (Refereed)
    Abstract [en]

    Background: Early appearance of antibodies specific for native human type II collagen (anti-CII) characterizes an early inflammatory and destructive phenotype in adults with rheumatoid arthritis (RA). The objective of this study was to investigate the occurrence of anti-CII, IgM RF, IgA RF and anti-CCP in serum samples obtained early after diagnosis, and to relate the occurrence of autoantibodies to outcome after eight years of disease in children with juvenile idiopathic arthritis (JIA). Methods: The Nordic JIA database prospectively included JIA patients followed for eight years with data on remission and joint damage. From this database, serum samples collected from 192 patients, at a median of four months after disease onset, were analysed for IgG anti-CII, IgM RF, IgA RF and IgG anti-CCP. Joint damage was assessed based on Juvenile Arthritis Damage Index for Articular damage (JADI-A), a validated clinical instrument for joint damage. Results: Elevated serum levels of anti-CII occurred in 3.1%, IgM RF in 3.6%, IgA RF in 3.1% and anti-CCP in 2.6% of the patients. Occurrence of RF and anti-CCP did to some extent overlap, but rarely with anti-CII. The polyarticular and oligoarticular extended categories were overrepresented in patients with two or more autoantibodies. Anti-CII occurred in younger children, usually without overlap with the other autoantibodies and was associated with high levels of C-reactive protein (CRP) early in the disease course. All four autoantibodies were significantly associated with joint damage, but not with active disease at the eight-year follow up. Conclusions: Anti-CII, anti-CCP, IgA RF and IgM RF detected early in the disease course predicted joint damage when assessed after eight years of disease. The role of anti-CII in JIA should be further studied.

    Determinants of lung function and airway hyperresponsiveness in asthmatic children2007In: Respiratory Medicine, ISSN 0954-6111, E-ISSN 1532-3064, Vol. 101, no 7, p. 1477-1482Article in journal (Refereed)
    Abstract [en]

    Background

    Asthma patients exhibit an increased rate of loss of lung function. Determinants to such decline are largely unknown and the modifying effect of steroid therapy is disputed. This cross-sectional study aimed to elucidate factors contributing to such decline and the possible modifying effect of steroid treatment.

    Methods

    We analyzed determinants of lung function and airway hyperresponsiveness (AHR) in a Scandinavian study of 2390 subjects from 550 families. Families were selected for the presence of two or more asthmatic children as part of a genetic study, Scandinavian Asthma Genetic Study (SAGA).

    Results

    The primary analysis studied the association between the lung function and delay of inhaled corticosteroids (ICS) after asthma diagnosis among asthmatic children and young adults with a history of regular ICS treatment (N=919). FEV1 percent predicted (FEV1% pred) was 0.25% lower per year of delay from diagnosis until treatment (p=0.039). This association was significantly greater in allergy skin prick test negative children. There was no significant influence of gender, age at asthma onset, or smoking.

    In the secondary analysis of the whole population of 2390 asthmatics and non-asthmatics, FEV1% pred was inversely related to having asthmatic siblings (−7.9%; p<0.0001), asthma diagnosis (−2.7%; p=0.0007), smoking (−3.5%; p=0.0027), and positive allergy skin prick test (−0.47% per test; p=0.012), while positively related to being of female gender (1.8%; p=0.0029). Risk of AHR was higher by having asthmatic siblings (OR 2.7; p<0.0001), being of female gender (OR 2.0; p<0.0001), and having asthma (OR 2.0; p<0.0001).

    Conclusions

    These data suggest that lung function is lower in asthmatics with delayed introduction of ICS therapy, smoking, and positive allergy skin prick test. Lung function is lower and AHR higher in female asthmatics and subjects with asthmatic siblings or established asthma.

    A population-based study of animal component sensitization, asthma, and rhinitis in schoolchildren2015In: Pediatric Allergy and Immunology, ISSN 0905-6157, E-ISSN 1399-3038, Vol. 26, no 6, p. 557-563Article in journal (Refereed)
    Abstract [en]

    BackgroundAnimal sensitization is a major determinant of asthma in children. Component-resolved studies of unselected pediatric populations are lacking. The aim was to describe sensitization to animal components and the association with asthma and rhinitis in animal-sensitized schoolchildren. MethodsA random sample of 696 children (11-12years) from a Swedish population-based cohort was tested for sensitization to cat, dog, and horse dander using ImmunoCAP. Sera from animal-sensitized children were further analyzed by microarray including three allergen components from cat, four from dog, and two from horse. The parents completed an expanded ISAAC questionnaire. ResultsOf 259 animal-sensitized children (0.1 kU(A)/l), 51% were sensitized to all three, 23% to two, and 25% to one species. Current asthma and asthma symptoms following contact with cats were associated with co-sensitization to Fel d 1 and Fel d 4. This association was seen already at moderate-level sensitization (1-15 ISU) to Fel d 4, at which level most children were sensitized to Fel d 1, as well. In dog-sensitized children, the majority was sensitized to more than one dog component, and co-sensitization to Can f 5 and Can f 1/f 2 conferred the greatest risk for asthma. Sensitization to the highly cross-reactive serum albumins was uncommon and not associated with asthma. ConclusionsAmong schoolchildren in northern Sweden, where mite allergy is uncommon, furry animals were the primary perennial sensitizers. Asthma was associated with higher levels of component sensitization, and sensitization to more than one component from the same animal conferred the greatest risk.

    Parents need support to find ways to optimise their own sleep without seeing their preterm infant's sleeping patterns as a problem2017In: Acta Paediatrica, ISSN 0803-5253, E-ISSN 1651-2227, Vol. 106, no 2, p. 223-228Article in journal (Refereed)
    Abstract [en]

    AIM: This study described how parents perceived their own sleep, and their infants', during neonatal intensive care unit (NICU) admission and after discharge. It also explored the infants' sleeping location at home.

    METHODS: The study was conducted in the NICUs of two Swedish university hospitals. The parents of 86 infants - 86 mothers and 84 fathers - answered questionnaires during their infants' hospital stay, at discharge and at the infants' corrected ages of two, six and 12 months. The parents' own sleep was explored with the Insomnia Severity Index.

    RESULTS: Mothers reported more severe insomnia than fathers during their infants' hospitalisation, and these higher insomnia severity scores were associated with more severe infant sleep problems at discharge (p = 0.027) and at two months (p = 0.006) and 12 months (p = 0.002) of corrected age. During the study period, 4%-10% of the parents reported severe or very severe infant sleeping problems. The bed-sharing rate was 75% after discharge and about 60% at the corrected age of 12 months.

    CONCLUSION: Maternal insomnia during an infant's hospital stay was associated with later perceptions of sleep problems in their children. Parents need support to find solutions for optimal sleep without seeing their child's sleeping patterns as a problem.

    'I felt a little bubbly in my tummy': Eliciting pre-schoolers' accounts of their health visit using a computer-assisted interview method.2016In: Child Care Health and Development, ISSN 0305-1862, E-ISSN 1365-2214, Vol. 42, no 1, p. 87-97Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: In the health care services, children's rights to participate in all matters that concern them are considered important. However, in practice this can be challenging with young children. In My Shoes (IMS) is a computer-assisted interview tool developed to help children talk about their experiences. The aim of the study was to evaluate the IMS' ability to elicit pre-schoolers' subjective experiences and accurate accounts of a routine health visit as well as the children's engagement in the interview process.

    METHODS: Interviews were conducted with 23 children aged 4-5 years, 2-4 weeks after their health visit. The interviews were transcribed verbatim and analysed using a method inspired by Content Analysis to evaluate IMS's ability to elicit accounts about subjective experiences. Accurate accounts were assessed by comparing the transcribed interviews with the filmed visits at the child health centre. The children's engagement was defined by the completion and length of the interviews, and the children's interaction with the software.

    RESULTS: All children gave accounts about their subjective experiences, such as their emotional state during the visit, available toys or rewards they received. All children related to the correct event, they all named at least one person who was present and 87% correctly named at least one examination procedure. The majority of children (91%) completed the interview, which lasted 17-39 min (M = 24), and 96% interacted with the IMS software.

    CONCLUSIONS: IMS was feasible to help children describe their health care experiences, in both detail and depth. The children interacted with the software and maintained their interest for an extended period of time.

    How can clinicians detect and treat autism early? Methodological trends of technology use in research2016In: Acta Paediatrica, ISSN 0803-5253, E-ISSN 1651-2227, Vol. 105, no 2, p. 137-144Article, review/survey (Refereed)
    Abstract [en]

    We reviewed original research papers that used quantifiable technology to detect early autism spectrum disorder (ASD) and identified 376 studies from 34 countries from 1965 to 2013. Publications have increased significantly since 2000, with most coming from the USA. Electroencephalogram, magnetic resonance imaging and eye tracking were the most frequently used technologies. Conclusion: The use of quantifiable technology to detect early ASD has increased in recent decades, but has had limited impact on early detection and treatment. Further scientific developments are anticipated, and we hope that they will increasingly be used in clinical practice for early ASD screening, diagnosis and intervention.

    Gaze-based assistive technology in daily activities in children with severe physical impairments-An intervention study.2017In: Developmental Neurorehabilitation, ISSN 1751-8423, E-ISSN 1751-8431, Vol. 20, no 3, p. 129-141Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: To establish the impact of a gaze-based assistive technology (AT) intervention on activity repertoire, autonomous use, and goal attainment in children with severe physical impairments, and to examine parents' satisfaction with the gaze-based AT and with services related to the gaze-based AT intervention.

    METHODS: Non-experimental multiple case study with before, after, and follow-up design. Ten children with severe physical impairments without speaking ability (aged 1-15 years) participated in gaze-based AT intervention for 9-10 months, during which period the gaze-based AT was implemented in daily activities.

    RESULTS: Repertoire of computer activities increased for seven children. All children had sustained usage of gaze-based AT in daily activities at follow-up, all had attained goals, and parents' satisfaction with the AT and with services was high.

    DISCUSSION: The gaze-based AT intervention was effective in guiding parents and teachers to continue supporting the children to perform activities with the AT after the intervention program.
