- Aim To describe survival and neonatal morbidities in infants born before 24 weeks of gestation during a 12-year period. Methods Data were retrieved from national registries and validated in medical files of infants born before 24 weeks of gestation 2007-2018 in Sweden. Temporal changes were evaluated. Results In 2007-2018, 282 live births were recorded at 22 weeks and 460 at 23 weeks of gestation. Survival to discharge from hospital of infants born alive at 22 and 23 weeks increased from 20% to 38% (p = 0.006) and from 45% to 67% (p < 0.001) respectively. Caesarean section increased from 12% to 22% (p = 0.038) for infants born at 22 weeks. Neonatal morbidity rates in infants alive at 40 weeks of postmenstrual age (n = 399) were unchanged except for an increase in necrotising enterocolitis from 0 to 33% (p = 0.017) in infants born at 22 weeks of gestation. Bronchopulmonary dysplasia was more common in boys than girls, 90% versus 82% (p = 0.044). The number of infants surviving to 40 weeks doubled over time. Conclusion Increased survival of infants born before 24 weeks of gestation resulted in increasing numbers of very immature infants with severe neonatal morbidities likely to have a negative impact on long-term outcome.

- Aim: This study investigated childhood diagnoses in children born extremely preterm before 24 weeks of gestation. Methods: Diagnoses of neurodevelopmental disorders and selected somatic diagnoses were retrospectively retrieved from national Swedish registries for children born before 24 weeks from 2007 to 2018. Their individual medical files were also examined. Results: We studied 383 children born at a median of 23.3 (range 21.9–23.9) weeks, with a median birthweight of 565 (range 340–874) grams. Three-quarters (75%) had neurodevelopmental disorders, including speech disorders (52%), intellectual disabilities (40%), attention deficit hyperactivity disorder (30%), autism spectrum disorders (24%), visual impairment (22%), cerebral palsy (17%), epilepsy (10%) and hearing impairment (5%). More boys than girls born at 23 weeks had intellectual disabilities (45% vs. 27%, p < 0.01) and visual impairment (25% vs. 14%, p < 0.01). Just over half of the cohort (55%) received habilitation care. The majority (88%) had somatic diagnoses, including asthma (63%) and failure to thrive/short stature (39%). Conclusion: Most children born before 24 weeks had neurodevelopmental disorders and/or additional somatic diagnoses in childhood and were referred to habilitation services. Clinicians should be aware of the multiple health and developmental problems affecting these children. Resources are needed to identify their long-term support needs at an early stage.

- Children born before 24 gestational weeks had high neonatal morbidity and a majority had one or more neurodevelopmental disorders in addition to somatic diagnoses in childhood. Active Swedish perinatal care of infants with gestational age <24 weeks has resulted in a survival rate of more than 50 percent. Resuscitation of these immature infants is controversial, and some countries offer comfort care only. In a retrospective review of medical files and registries of 399 Swedish infants born before 24 gestational weeks, a majority had severe prematurity-related neonatal diagnoses. In childhood (2-13 years), 75 percent had at least one neurodevelopmental disorder and 88 percent had one or more prematurity-related somatic diagnosis (permanent or transient) that was likely to affect their quality of life. Long-term consequences for surviving infants should be considered in general recommendations as well as in parental information.

- Objectives To retrospectively evaluate ophthalmological and neurological outcomes in a Swedish cohort of infants born before 24 weeks gestational age (GA) and explore risk factors for visual impairment. Setting Eye and paediatric clinics in Sweden. Participants Infants screened for retinopathy of prematurity (ROP) (n=399), born before 24 weeks GA, 2007-2018. Cases were excluded if ophthalmological follow-up records could not be traced. Primary and secondary outcome measures Primary outcomes were ophthalmological, including visual acuity (VA), refractive error, strabismus, nystagmus and cerebral visual impairment (CVI). Secondary outcomes comprised neonatal and neurological morbidities. Data were retrospectively retrieved from medical records. Results The 355 assessed children had a median GA of 23 weeks and 2 days and a median birth weight of 565 g. At the last available ophthalmological examination, the median age was 4.8 years (range 0.5-13.2 years). Nystagmus was recorded in 21.1%, strabismus in 34.8%, and 51.0% wore spectacles. Seventy-three of 333 (21.9%) were visually impaired, defined as being referred to a low vision clinic and/or having a VA less than 20/60 at 3.5 years of age or older. ROP treatment was a significant risk factor for visual impairment (OR 2.244, p=0.003). Visually impaired children, compared with children without visual impairment, more often had neurological deficits such as intellectual disability 63.8% versus 33.3% (p<0.001), epilepsy 21.1% versus 7.5% (p=0.001) and autism spectrum disorders 32.8% versus 20.9% (p=0.043). Nine of the 355 children had been diagnosed with CVI. Conclusions Children born before 24 weeks GA frequently had visual impairment in association with neurological deficits. CVI was rarely diagnosed. A multidisciplinary approach for the evaluation and habilitation of these vulnerable infants is warranted. National follow-up guidelines need to be developed and implemented.

- Aims: The aim of this study was to determine the incidence of neonatal morbidity in extremely preterm infants and to identify associated risk factors. Methods: Population based study of infants born before 27 gestational weeks and admitted for neonatal intensive care in Sweden during 2004-2007. Results: Of 638 admitted infants, 141 died. Among these, life support was withdrawn in 55 infants because of anticipation of poor long-term outcome. Of 497 surviving infants, 10% developed severe intraventricular haemorrhage (IVH), 5.7% cystic periventricular leucomalacia (cPVL), 41% septicaemia and 5.8% necrotizing enterocolitis (NEC); 61% had patent ductus arteriosus (PDA) and 34% developed retinopathy of prematurity (ROP) stage >= 3. Eighty-five per cent needed mechanical ventilation and 25% developed severe bronchopulmonary dysplasia (BPD). Forty-seven per cent survived to one year of age without any severe IVH, cPVL, severe ROP, severe BPD or NEC. Tocolysis increased and prolonged mechanical ventilation decreased the chances of survival without these morbidities. Maternal smoking and higher gestational duration were associated with lower risk of severe ROP, whereas PDA and poor growth increased this risk. Conclusion: Half of the infants surviving extremely preterm birth suffered from severe neonatal morbidities. Studies on how to reduce these morbidities and on the long-term health of survivors are warranted.

- Intestinal alkaline sphingomyelinase (Alk-SMase) and neutral ceramidase may catalyze the hydrolysis of endogenous sphin-gomyelin (SM) and milk SM in human-milk fed infants. The enzymes generate sphingolipid metabolites that may influence gut maturation. Alk-SMase also inactivates platelet-activating factor (PAF) that is involved in the pathogenesis of necrotizing enterocolitis (NEC). We examined whether the two enzymes are expressed in both preterm and term infants and analyzed Alk-SMase, neutral ceramidase, SM, and sphingolipid metabolites in meconium. Meconium was collected from 46 preterm (gestational ages 23-36 wk) and 38 term infants (gestational ages 37-42 wk) and analyzed for Alk-SMase using C-14-choline-labeled SM and for neutral ceramidase using C-14-octanoyl-sphingosine as substrates. Molecular species of SM, ceramide, and sphingosine were analyzed by high-performance liquid chromatography mass spectroscopy. Meconium contained significant levels of Alk-SMase and ceramidase at all gestational ages. It also contained 16-24 carbon molecular species of SM, palmitoyl-and stearoyl-sphingosine, and sphingosine. There were positive correlations between levels of SM and ceramide and between ceramide and sphingosine levels. In conclusion, Alk-SMase and ceramidase are expressed in the gut of both preterm and term newborn infants and may generate bioactive sphingolipid messengers.

- Context: IGF-I and IGF binding protein-3 (IGFBP-3) are essential for growth and maturation of the developing brain. Objective: The aim of this study was to evaluate the association between postnatal serum concentrations of IGF-I and IGFBP-3 and brain volumes at term in very preterm infants. Design: Fifty-one infants with a mean (sd) gestational age (GA) of 26.4 (1.9) wk and birth weight (BW) of 888 (288) g were studied, with weekly blood sampling of IGF-I and IGFBP-3 from birth until 35 gestational weeks (GW) and daily calculation of protein and caloric intake. Magnetic resonance images obtained at 40 GW were segmented into total brain, cerebellar, cerebrospinal fluid, gray matter, and unmyelinated white matter volumes. Main Outcome Measures: We evaluated brain growth by measuring brain volumes using magnetic resonance imaging. Results: Mean IGF-I concentrations from birth to 35 GW correlated with total brain volume, unmyelinated white matter volume, gray matter volume, and cerebellar volume [r = 0.55 (P < 0.001); r = 0.55 (P < 0.001); r = 0.44 (P = 0.002); and r = 0.58 (P < 0.001), respectively]. Similar correlations were observed for IGFBP-3 concentrations. Correlations remained after adjustment for GA, mean protein and caloric intakes, gender, severe brain damage, and steroid treatment. Protein and caloric intakes were not related to brain volumes. Infants with BW small for GA had lower mean concentrations of IGF-I (P = 0.006) and smaller brain volumes (P = 0.001-0.013) than infants with BW appropriate for GA. Conclusion: Postnatal IGF-I and IGFBP-3 concentrations are positively associated with brain volumes at 40 GW in very preterm infants. Normalization of the IGF-I axis, directly or indirectly, may support normal brain development in very preterm infants.

- IMPORTANCE Lack of arachidonic acid (AA) and docosahexaenoic acid (DHA) after extremely preterm birth may contribute to preterm morbidity, including retinopathy of prematurity (ROP). OBJECTIVE To determine whether enteral supplementation with fatty acids from birth to 40 weeks' postmenstrual age reduces ROP in extremely preterm infants. DESIGN, SETTING, AND PARTICIPANTS The Mega Donna Mega trial, a randomized clinical trial, was a multicenter study performed at 3 university hospitals in Sweden from December 15, 2016, to December 15, 2019. The screening pediatric ophthalmologists were masked to patient groupings. A total of 209 infants born at less than 27 weeks' gestation were tested for eligibility, and 206 infants were included. Efficacy analyses were performed on as-randomized groups on the intention-to-treat population and on the per-protocol population using as-treated groups. Statistical analyses were performed from February to April 2020. INTERVENTIONS Infants received either supplementation with an enteral oil providing AA (100mg/kg/d) and DHA (50mg/kg/d) (AA:DHA group) or no supplementation within 3 days after birth until 40 weeks' postmenstrual age. MAIN OUTCOMES AND MEASURES The primary outcomewas severe ROP (stage 3 and/or type 1). The secondary outcomes were AA and DHA serum levels and rates of other complications of preterm birth. RESULTS A total of 101 infants (58 boys [57.4%]; mean [SD] gestational age, 25.5 [1.5] weeks) were included in the AA:DHA group, and 105 infants (59 boys [56.2%]; mean [SD] gestational age, 25.5 [1.4] weeks) were included in the control group. Treatment with AA and DHA reduced severe ROP compared with the standard of care (16 of 101 [15.8%] in the AA:DHA group vs 35 of 105 [33.3%] in the control group; adjusted relative risk, 0.50 [95% CI, 0.28-0.91]; P =.02). The AA:DHA group had significantly higher fractions of AA and DHA in serum phospholipids compared with controls (overall mean difference in AA:DHA group, 0.82 mol% [95% CI, 0.46-1.18 mol%]; P <.001; overall mean difference in control group, 0.13 mol% [95% CI, 0.01-0.24 mol%]; P =.03). There were no significant differences between the AA:DHA group and the control group in the rates of bronchopulmonary dysplasia (48 of 101 [47.5%] vs 48 of 105 [45.7%]) and of any grade of intraventricular hemorrhage (43 of 101 [42.6%] vs 42 of 105 [40.0%]). In the AA:DHA group and control group, respectively, sepsis occurred in 42 of 101 infants (41.6%) and 53 of 105 infants (50.5%), serious adverse events occurred in 26 of 101 infants (25.7%) and 26 of 105 infants (24.8%), and 16 of 101 infants (15.8%) and 13 of 106 infants (12.3%) died. CONCLUSIONS AND RELEVANCE This study found that, compared with standard of care, enteral AA:DHA supplementation lowered the risk of severe ROP by 50% and showed overall higher serum levels of both AA and DHA. Enteral lipid supplementation with AA:DHA is a novel preventive strategy to decrease severe ROP in extremely preterm infants.

- Introduction: Children born extremely preterm have high risk of visual impairment due to retinopathy of prematurity (ROP) and cerebral lesions. Objective: The aim of this study was to investigate the frequency of ROP and visual impairment as defined by the World Health Organization (WHO), with respect to gender in two hospital-based groups of children born at the limit of viability. Patients and methods: A retrospective chart review was conducted for all children (n = 114), born before 25 gestational weeks and screened for ROP at Karolinska hospital in Stockholm and Sahlgrenska hospital in Gothenburg between 1990 and 2002. Maximal ROP stages, treatment for ROP and visual acuity (VA), with correction when needed at latest available visit, were recorded. Results: Altogether 97.4% had ROP, 74.6% developed proliferative disease (stage >/= 3) and 63.2% were treated with retinal ablation. Normal VA (>/=0.8) in at least one eye was found in 50.5% of all and in significantly more girls (61.5%) than boys (34.8%) (p = 0.006), while visual impairment (VA < 0.33) was more common in boys (32.6%) than in girls (9.2%) (p = 0.004). Conclusion: A large proportion of children, especially boys, born at the level of viability are visually impaired with low vision or blindness. Development of preventive measures is urgent.

- PURPOSE: To describe the process of becoming aware of and acting on personal cardiovascular (CVD) risk in type 2 diabetes (T2D).METHOD: A purposive sample of 14 persons living with T2D participated in semi-structured, open-ended, in-dept interviews. The interviews were analysed with grounded theory.RESULT: The analysis identified the core category "Balancing emotions, integrating knowledge and understanding to achieve risk awareness and act on it." Five categories describe the movement from not being aware of the risk of cardiovascular disease (CVD) to becoming aware of this risk and taking action to reduce it. Persons with T2D need to transform their knowledge and experience of CVD risk and incorporate it in their individual situations. Emotional and existential experiences of CVD risk can lead to awareness about the severity of the condition and contribute to increased motivation for self-management. However, an overly high emotional response can be overwhelming and may result in insufficient self-management.CONCLUSION: Persons with T2D seemed not to fully grasp their increased risk of CVD or recognize that self-management activities were aimed at reducing this risk. However, their awareness of CVD risk gradually increased as they came to understand the severity of T2D and became more emotionally and existentially engaged.

- Background:In preterm infants, low levels of insulin-like growth factor-I (IGF-I) and IGF binding protein 3 (IGFBP-3) are associated with impaired brain growth and retinopathy of prematurity (ROP). Treatment with IGF-I/IGFBP-3 may be beneficial for brain development and may decrease the prevalence of ROP.Methods:In a phase II pharmacokinetics and safety study, five infants (three girls) with a median (range) gestational age (GA) of 26 wk + 6 d (26 wk + 0 d to 27 wk + 2 d) and birth weight of 990 (900-1,212) g received continuous intravenous infusion of recombinant human (rh)IGF-I/rhIGFBP-3. Treatment was initiated during the first postnatal day and continued for a median (range) duration of 168 (47-168) h in dosages between 21 and 111 µg/kg/24 h.Results:Treatment with rhIGF-I/rhIGFBP-3 was associated with higher serum IGF-I and IGFBP-3 concentrations (P < 0.001) than model-predicted endogenous levels. Of 74 IGF-I samples measured during study drug infusion, 37 (50%) were within the target range, 4 (5%) were above, and 33 (45%) were below. The predicted dose of rhIGF-I/rhIGFBP-3 required to establish circulating levels of IGF-I within the intrauterine range in a 1,000 g infant was 75-100 µg/kg/24 h. No hypoglycemia or other adverse effects were recorded.Conclusion:In this study, continuous intravenous infusion of rhIGF-I/rhIGFBP-3 was effective in increasing serum concentrations of IGF-I and IGFBP-3, and was found to be safe.

- Objective Prematurity is a major risk factor for retinopathy of prematurity (ROP). We aimed to elucidate ROP prevalence, treatment and retreatment in infants born before 24 gestational age (GA) weeks in a Swedish cohort. Methods and analysis Infants with completed ROP screening, born at <24 GA weeks, 2007-2018 in Sweden were included. Data of GA, birth weight (BW), sex, neonatal morbidities, maximal ROP stage, aggressive posterior ROP (APROP), ROP treatments, treatment modality and treatment centre were retrieved. Results In total, 399 infants, with a mean GA of 23.2 weeks (range 21.9-23.9) and a mean BW of 567 g (range 340-874), were included. ROP was detected in 365 (91.5%) infants, 173 (43.4%) were treated for ROP and 68 of 173 (39.3%) were treated more than once. As the first treatment, 142 (82.0%) received laser and 29 (16.1%) received intravitreal injection of antivascular endothelial growth factor (anti-VEGF). Retreatment was performed after first laser in 46 of 142 (32.4%) and in 20 of 29 (69.0%) after first anti-VEGF treatment. Retreatment rate was not associated with GA, BW or sex but with APROP, treatment method (anti-VEGF) and treatment centre where the laser was performed (p<0.001). Twenty eyes progressed to retinal detachment, and two infants developed unilateral endophthalmitis after anti-VEGF treatment. Conclusion Infants, born at <24 weeks GA, had high rates of treatment-warranting ROP and retreatments. Treatment centre highly influenced the retreatment rate after laser indicating that laser treatment could be improved in some settings.

- Background We investigated ophthalmological outcomes at 2.5 years of corrected age in children born extremely preterm (EPT) to evaluate the effects of postnatal enteral supplementation with omega-3 and omega-6 long-chain polyunsaturated fatty acids.Methods In the Mega Donna Mega clinical trial, EPT infants born at less than 28 weeks of gestation were randomized to receive an enteral supplementation of docosahexaenoic acid (DHA) and arachidonic acid (AA) from birth to 40 weeks postmenstrual age. In this exploratory follow-up at 2.5 years of corrected age, we assessed visual acuity (VA), refraction, manifest strabismus, and nystagmus. Satisfactory VA was defined as >= 20/63. Multiple imputation (MI) was used to address the issue of missing data.Findings Of 178 children in the trial, 115 (with median gestational age (GA) of 25 + 4/7 weeks and median birth weights of 790 g) were ophthalmologically assessed at a median corrected age of 2.7 years (range 2.0-3.9 years). VA assessment was missing in 42.1% (75/178), in 41.7% (35/84) of the AA/DHA supplemented infants, and in 42.6% (40/94) of the control infants. After MI and adjustments for GA, study center, plurality, and corrected age at VA exam, no significant effect of AA/DHA supplementation was detected in VA outcome (>= 20/63) (odds ratio 2.16, confidence interval 95% 0.99-4.69, p = 0.053).Interpretation In this randomized controlled trial follow-up, postnatal supplementation with enteral AA/DHA to EPT children did not significantly alter VA at 2.5 years of corrected age. Due to the high loss to follow-up rate and the limited statistical power, additional studies are needed.

- BACKGROUND: To evaluate the relationships between postnatal change in circulatory insulin-like growth factor-I (IGF-I) concentrations, brain volumes, and developmental outcome at 2 y of age in very preterm infants. METHODS: IGF-I was measured weekly, and nutritional intake was calculated daily from birth until a postmenstrual age (PMA) of 35 wk. Individual beta coefficients for IGF-I, IGF-I(B), representing the rate of increase in IGF-I from birth until a PMA of 35 wk were calculated. Brain magnetic resonance imaging was performed at term age, with segmentation into total brain, cerebellar, gray matter, and unmyelinated white matter volume (UWMV). Developmental outcome was evaluated using Bayley Scales of Infant Development-II. RESULTS: Forty-nine infants, with mean gestational age (GA) of 26.0 wk, were evaluated at mean 24.6 mo corrected age. Higher IGF-I(B), UWMV, and cerebellar volume were associated with a decreased risk for a Mental Developmental Index (MDI) <85 (odds ratio (95% confidence interval): 0.6 (0.4-0.9), 0.96 (0.94-0.99), and 0.78 (0.6-0.96), respectively). In multivariate analysis, higher IGF-I(B) and higher UWMV combined with female gender constituted the two models with the highest predictive value for MDI > 85. CONCLUSION: A higher rate of increase in circulating IGF-I is associated with a decreased risk for subnormal MDI at 2 y of corrected age. This relationship is in part dependent on brain volume at term age.

- OBJECTIVE: To assess quality of life after continent ileal reservoir diversion in children and adolescents. MATERIAL AND METHODS: Nine boys and 9 girls (10.8-18 years old at surgery) were operated with a Kock reservoir and followed for 5-12 years. They participated in an interview using a questionnaire based on the Swedish self-esteem inventory, "I think I am". The questionnaire consisted of 76 questions that covered medical, physical, psychological, social, body image and sexual aspects. RESULTS: Six of 18 patients had some difficulties on catheterization. Five complained of pain or bleeding during evacuation. Two patients had slight urinary leakage between evacuations and 6 had mucus secretion. Ten patients had diarrhea with different frequencies. Physical activities were not hampered by the operation in any patient. Instead, activities such as full day outside home, friend at home overnight, using all types of clothes, and participation in camps were increased in 8, 6, 5 and 5 patients, respectively. All patients but 2 had an excellent relation with friends and family members. More than half of patients had excellent positive self-esteem and body image and the rest had very good self-esteem. However, some patients were concerned about how they looked and felt that life was unfair to them. CONCLUSIONS: The patients were satisfied with their operation. They were physically active and declared a positive perspective regarding self-esteem and body image. The medical problems related to the operation did not have any negative influence on the self-esteem or body image. The choice of the operation can only be determined on the basis of an attentive dialogue between surgeon, child and parents.

- Senaste halvåret har en arbetsgrupp på Svenska Psykiatriska Föreningens uppdrag arbetat med problem som finns runt psykiatriska diagnoser. En viktig del av arbetet har varit att ta fram ett diskussionsunderlag främst riktat till dem som i sitt arbete sätter psykiatriska diagnoser. Detta underlag syftar till att problematisera, inte till att polemisera. Självklart har vi i gruppen uppfattningar, men vi har inte alltid samma uppfattningar inom detta område. En sak är vi dock helt överens om – psykiatrisk diagnostik är svårt! samt att det idag finns uppenbara problem.

Tidskriftsartikel (refereegranskat)abstract
- Introduction Idiopathic Normal Pressure Hydrocephlaus (iNPH) is, despite a vastly improved knowledge of the disorder since its first description still underdiagnosed and undertreated. Because of this, there is a need for further large studies describing the typical symptomatology and reversibility of symptoms in iNPH, which was the aim of this study. Methods In all, 429 patients (mean age 71years) were included. Detailed pre- and postoperative examinations of symptoms and signs were analyzed. A composite outcome measure was constructed. Results Sixty-eight % improved after surgery. Preoperatively, 72% exhibited symptoms from three or four of the assessed domains (gait, balance, neuropsychology and continence) while 41% had symptoms from all four domains. Ninety % had gait disturbances, of which 75% had broad-based gait, 65% shuffling gait and 30% freezing of gait. These disturbances coexisted in most patients preoperatively, but were more likely to appear as isolated findings after surgery. Impaired balance was seen in 53% and retropulsion in 46%. MMSE <25 was seen in 53% and impaired continence in 86%. Improvements were seen in all symptom domains postoperatively. Conclusions The iNPH phenotype is characterized by a disturbance in at least 3/4 symptom domains in most patients, with improvements in all domains after shunt surgery. Most patients present with a broad-based and shuffling gait as well as paratonia. Present symptoms in all domains and a shuffling gait at the time of diagnosis seem to predict a favorable postoperative outcome, whereas symptom severity does not.

- AIMS: To characterize ophthalmological findings in a sample of Swedish children aged 4-15 years.METHODS: A prospective cross-sectional comprehensive ophthalmological investigation was performed on a sample of 143 children (67 girls, 76 boys) aged 4-15 years.RESULTS: Visual acuity (VA) in the better eye >or=1.0 (0.3 logMAR). Amblyopia was found in 0.7% of subjects. A total of 68% of the children had no refractive errors. Hyperopia (>or=2.0 dioptres [D] in spherical equivalent [SE]) was found in 9% and myopia (>or=0.5 D SE) in 6% of children. Astigmatism (>or=0.75 D) was recorded in 22% and anisometropia (>or=1.0 D SE) in 3%. A total of 8% were optically corrected. Strabismus was recorded in 3.5%. Signs of visuoperceptual problems were reported in 3% of the children.CONCLUSION: This sample of Swedish children may serve as a comparison group regarding ophthalmological findings in children aged 4-15 years.

A randomized trial of delayed versus early cord clamping: iron status and neurodevelopment at 12 months of age
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- 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.

- 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.

- 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 μg/L v 81 μg/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. Trial registration Clinical Trials NCT01245296.

- 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.

- 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 pCO(2). 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 theDCC (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.

- 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 4months of life.Methods Full-term infants (n=382) were randomised to delayed (180sec) or early cord clamping (10sec). The Ages and Stages Questionnaire (ASQ) was used to assess neurodevelopment at 4months. Immunoglobulin G was measured at birth, 23days and 4months. Parents recorded any symptoms indicating infection during the first 4months 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 4months 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 23days (11.7 vs. 11.0g/L, p=0.004), but did not differ between the groups at 4months. Symptoms of infection were comparable between the groups.Conclusion Delayed cord clamping did not affect overall neurodevelopment or symptoms of infection up to 4months of age, but may have an impact on specific neurodevelopmental domains.

Effects of Delayed versus Early Cord Clamping on Healthy Term Infants
- 2013

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- 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.

- 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.

- Hydrocephalus in children has many aetiologies, and can cause multiple ophthalmic and visual disorders. This study sets out to detect and quantify visual and visuoperceptual dysfunction in children who have received surgical treatment for hydrocephalus with and without myelomeningocele, and to relate the results to the associated diagnoses and results from a comparison group. Seventy-five school-aged children (41 males, 34 females) with surgically-treated hydrocephalus and 140 comparison children (76 males, 64 females) matched for age and sex underwent comprehensive ophthalmologic examination. Median age at examination was 9 years and 4 months (range 7 y 4 mo-12 y 10 mo). Visual function deficits were identified in 83% (62/75) of the children with hydrocephalus. Visual impairment (binocular visual acuity <0.3) was found in 15% (11/73; comparison group 0%) but in none with myelomeningocele. Strabismus was found in 69% (51/74; comparison group 4% [5/140], p < 0.001), and refractive errors were found in 67% (47/70; comparison group 20% [28/140], p < 0.001). Cognitive visual dysfunction was identified in 59% (38/64; comparison group 3% [4/140], p < 0.001). These disorders were identified in various combinations and comprised impaired ability to plan movement through depth (e.g. going down a stair), impaired simultaneous perception, impaired perception of movement, impaired orientation, and (least frequently) impaired recognition. In this study, children with hydrocephalus associated with myelomeningocele were least commonly affected. Visual disorders were most frequent in those with epilepsy, cerebral palsy, and/or cognitive disability.

- ObjectiveTo determine the utility of symptoms, signs, comorbidities and background variables for the prediction of outcome of treatment in iNPH. MethodsA prospective observational study of consecutively included iNPH patients, who underwent neurological, physiotherapeutic and neuropsychological assessments before and after shunt surgery. The primary outcome measure was the total change on the iNPH scale, and patients were defined as improved postoperatively if they had improved by at least five points on that scale. Results143 iNPH patients were included, and 73% of those were improved after surgery. None of the examined symptoms or signs could predict which patients would improve after shunt surgery. A dominant subjective complaint of memory problems at baseline was predictive of non-improvement. The reported comorbidities, duration of symptoms and BMI were the same in improved and non-improved patients. Each of the symptom domains (gait, neuropsychology, balance, and continence) as well as the total iNPH scale score improved significantly (from median 53 to 69, p < 0.001). The proportions of patients with shuffling gait, broad-based gait, paratonic rigidity and retropulsion all decreased significantly. DiscussionThis study confirms that the recorded clinical signs, symptoms, and impairments in the adopted clinical tests are characteristic findings in iNPH, based on that most of them improved after shunt surgery. However, our clinical data did not enable predictions of whether patients would respond to shunt surgery, indicating that the phenotype is unrelated to the reversibility of the iNPH state and should mainly support diagnosis. Absence of specific signs should not be used to exclude patients from treatment.

Tidskriftsartikel (refereegranskat)abstract
- Background: There is increasing research that examines gender-issues in multiple sclerosis (MS), but little focus has been placed on gender-issues regarding physical activity. The aim of the present study was to describe levels of physical activity, self-efficacy for physical activity, fall-related self-efficacy, social support for physical activity, fatigue levels and the impact of MS on daily life, in addition to investigating gender differences. Methods: The sample for this cross-sectional cohort study consisted of 287 (84 men; 29.3%) adults with MS recruited from the Swedish Multiple Sclerosis Registry. A questionnaire was sent to the subjects consisting of the self-administrated measurements: Physical Activity Disability Survey - Revised, Exercise Self-Efficacy Scale, Falls-Efficacy Scale (Swedish version), Social Influences on Physical Activity, Fatigue Severity Scale and Multiple Sclerosis Impact Scale. Response rate was 58.2%. Results: Men were less physically active, had lower self-efficacy for physical activity and lower fall-related self-efficacy than women. This was explained by men being more physically affected by the disease. Men also received less social support for physical activity from family members. The level of fatigue and psychological consequences of the disease were similar between the genders in the total sample, but subgroups of women with moderate MS and relapsing remitting MS experienced more fatigue than men. Conclusions: Men were less physically active, probably a result of being more physically affected by the disease. Men being more physically affected explained most of the gender differences found in this study. However, the number of men in the subgroup analyses was small and more research is needed. A gender perspective should be considered in strategies for promoting physical activity in subjects with MS, e. g. men may need more support to be physically active.

- Background: The benefits of physical activity in persons with Multiple Sclerosis (MS) are considerable. Knowledge about factors that correlate to physical activity is helpful in order to develop successful strategies to increase physical activity in persons with MS. Previous studies have focused on correlates to physical activity in MS, however falls self-efficacy, social support and enjoyment of physical activity are not much studied, as well as if the correlates differ with regard to disease severity. The aim of the study was to examine associations between physical activity and age, gender, employment, having children living at home, education, disease type, disease severity, fatigue, self-efficacy for physical activity, falls self-efficacy, social support and enjoyment of physical activity in a sample of persons with MS and in subgroups with regard to disease severity.Methods: This is a cross-sectional survey study including Swedish community living adults with MS, 287 persons, response rate 58.2%. The survey included standardized self-reported scales measuring physical activity, disease severity, fatigue, self-efficacy for physical activity, falls self-efficacy, and social support. Physical activity was measured by the Physical Activity Disability Survey – Revised.Results: Multiple regression analyzes showed that 59% (F(6,3)=64.9, p=0.000) of the variation in physical activity was explained by having less severe disease (β=-0.30), being employed (β=0.26), having high falls self-efficacy (β=0.20), having high self-efficacy for physical activity (β=0.17), and enjoying physical activity (β=0.11). In persons with moderate/severe MS, self-efficacy for physical activity explained physical activity.Conclusions: Consistent with previous research in persons with MS in other countries this study shows that disease severity, employment and self-efficacy for physical activity are important for physical activity. Additional important factors were falls self-efficacy and enjoyment. More research is needed to confirm this and the subgroup differences.

- PURPOSE: The purpose was to evaluate the psychometric properties of physical activity measures in persons with multiple sclerosis (PwMS).METHODS: Adults with multiple sclerosis were recruited, n = 30 (validation) and n = 57 (test-retest). Steps measured with PiezoRX, Yamax SW200 and ActiGraph GT9X Link (AGlink) and time in different positions measured with AGlink were validated against data from video analysis. Psychometric properties of the Physical Activity and Disability Survey - Revised Swedish version (PADS-R(Sw)) was evaluated.RESULTS: The most valid measures were AGlink using the low-frequency extension filter, and PiezoRX with median absolute percentage errors (MeAPEs) of 0.9-3.1% and 1.3-3.3%. The MeAPEs were higher for Yamax SW200 (2.9-21.0%), AGlink display (3.6-44.8%) and AGlink normal filter (8.9-48.9%), indicating low validity. AGlink was not valid in measurements of sitting (MeAPE 12.0-12.5%) or lying (MeAPE 31.0-41.7%). The correlation between PADS-R(Sw) and AGlink steps was r = 0.492 (p = .009). The relative reliability of PADS-R(Sw) was ICC2,1 0.85 (CI 0.76-0.91), and absolute reliability was SEM 0.54.CONCLUSION: AGlink and PiezoRX were valid measures of steps in PwMS. The questionnaire PADS-R(Sw) was valid, with high relative reliability, but its absolute reliability was unsatisfactory.

- PURPOSE: To investigate strabismus, head posture, nystagmus, stereoacuity, ocular motility, near point of convergence (NPC) and accommodative convergence to accommodation ratio (AC/A) in a sample of Swedish children. METHODS: A prospective cross-sectional study was carried out on 143 children, 4-15 years of age. RESULTS: Heterotropia was found in five children (3.5%), four with esotropia and one with exotropia. One child with esotropia had a slight overaction of both inferior oblique muscles. Heterophoria was found in 37 children (26%) at near and/or distance fixation and it was four times more common at near than at distance. In 29 children, heterophoria was found at one distance only and orthophoria at the other. Orthophoria at both near and distance fixation was noted in 101 children (70.5%). The near point of convergence was < or =6 cm in 97% of the children and 97% had stereoacuity of 60" or better. In the whole group, the median AC/A ratio calculated with the heterophoria method was 5.6/1 prism diopters/diopters (PD/D) and with the gradient method, 1.3/1 PD/D. No anomalous head postures or nystagmus were observed and all children had normal versions. CONCLUSION: In this study, 143 well-defined children were investigated with a battery of accurately described tests, commonly used in clinical practice. These results are in agreement with those of other studies examining one or few variables in larger populations and the authors therefore conclude that their results may be used for comparisons with different patient groups.

- PURPOSE: To investigate heterotropia, heterophoria, head posture, nystagmus, stereo acuity, ocular motility and near point of convergence (NPC) in children with hydrocephalus treated surgically before 1 year of age. In addition, the effects of being born with hydrocephalus, the effect of the etiology of hydrocephalus, number of shunt revisions and the size of the ventricles on these variables were studied. METHODS: A population-based study was performed in 75 children and the results were compared with the results of an age- and sex-matched group (comp group) (n = 140). RESULTS: Heterotropia 68.9% (comp group 3.6%; p < 0.001), abnormal head posture 41.3% (comp group 0; p < 0.001), nystagmus 44.0% (comp group 0; p < 0.001), stereo acuity < or =60'' 33.8% (comp group 97.1%; p < 0.001) and ocular motility defects 69.7% (comp group 0.7%; p < 0.001) were more common among children with hydrocephalus than in the comparison group. Children with overt hydrocephalus at birth had significantly more heterotropia (p = 0.0006), esotropia (p = 0.002), abnormal head posture (p = 0.02) and motility defects (p = 0.003) compared to those with hydrocephalus developing during the first year of life. The etiology, number of shunt revisions and the size of the ventricles had no significant effect on any of the investigated variables. CONCLUSIONS: Children with hydrocephalus surgically treated before the age of one year commonly present orthoptic abnormalities. The etiology of hydrocephalus, number of shunt revisions and ventricle size seem to be of minor importance compared with the age of onset of hydrocephalus with regard to the risk for orthoptic abnormalities.

Tidskriftsartikel (refereegranskat)abstract
- Background and objective: Umbilical cord blood (UCB) is a valuable stem cell source used for transplantation. Immediate umbilical cord (UC) clamping is widely practised, but delayed UC clamping is increasingly advocated to reduce possible infant anaemia. The aim of this study was to investigate an intermediate UC clamping time point and to evaluate iron status at the age of 4 months in infants who had the UC clamped after 60 s and compare the results with immediate and late UC clamping. Design: Prospective observational study with two historical controls. Setting: A university hospital in Stockholm, Sweden, and a county hospital in Halland, Sweden. Methods: Iron status was assessed at 4 months in 200 prospectively recruited term infants whose UC was clamped 60 s after birth. The newborn baby was held below the uterine level for the first 30 s before placing the infant on the mother's abdomen for additional 30 s. The results were compared with data from a previously conducted randomised controlled trial including infants subjected to UC clamping at ≤10 s (n=200) or ≥180 s (n=200) after delivery. Results: After adjustment for age differences at the time of follow-up, serum ferritin concentrations were 77, 103 and 114 μg/L in the 10, 60 and 180 s groups, respectively. The adjusted ferritin concentration was significantly higher in the 60 s group compared with the 10 s group (P=0.002), while the difference between the 60 and 180 s groups was not significant (P=0.29). Conclusion: In this study of healthy term infants, 60 s UC clamping with 30 s lowering of the baby below the uterine level resulted in higher serum ferritin concentrations at 4 months compared with 10 s UC clamping. The results suggest that delaying the UC clamping for 60 s reduces the risk for iron deficiency. © 2017 Article author(s).

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: To determine the congruence between self-reported and objective data on incontinence, voided volume (VV) and voiding frequency (VF), in a prospective study of treatment of functional urinary incontinence (UI) due to urge syndrome or dysfunctional voiding in children. PATIENTS AND METHODS: In all, 202 children, enrolled in the European Bladder Dysfunction Study (EBDS), provided self-reported data on UI, VV and VF, before and after treatment, with validated questionnaires and 72-h voiding diaries. Objective data were obtained with uroflowmetry and a 12-h pad test, also before and after treatment. Questionnaires and diaries were checked and scored by a urotherapist, at scheduled office visits that were combined with uroflowmetry. RESULTS: At entry, parents under-reported UI on the questionnaires in 45% of cases, compared with the urotherapist's scores, and the 12-h pad test sensitivity for UI was only 64% (95% confidence interval 55-73%). The voiding diaries had inconsistent entries on UI and on VV. VF was overestimated in the questionnaires and underestimated in the diaries, compared with the urotherapist's scores. A VF of >7/day decreased significantly after EBDS treatment, but with no correlation with treatment outcome. The mean VV increased significantly after treatment for UI, also with no correlation with treatment outcome. CONCLUSIONS: Voiding diaries and questionnaires are useful tools for charting individual treatment and for screening, but they are ill-suited to documenting outcome variables in urge syndrome or dysfunctional voiding, because of over- and under-reporting. VV and VF lack specificity as outcome variables in children with urge syndrome or dysfunctional voiding. The 12-h pad test is not sensitive enough to complement self-reported symptoms of UI in children with urge syndrome or dysfunctional voiding. Clinical studies on UI rely on complaints and self-reported symptoms, but in children the reporting should be supervised by a trained urotherapist, to provide the necessary checks and balances.

- Background and purpose The effect of age on the distribution of morphine and morphine-3-glucuronide (M3G) across the blood-brain barrier (BBB) was studied in a sheep model utilizing intracerebral microdialysis. The effect of neonatal asphyxia on brain drug distribution was also studied. Experimental approach Microdialysis probes were inserted into the cortex, striatum and blood of 11 lambs (127 gestation days) and six ewes. Morphine, 1 mg.kg(-1), was intravenously administered as a 10 min constant infusion. Microdialysis and blood samples were collected for up to 360 min and analysed using liquid chromatography-tandem mass spectrometry. The half-life, clearance, volume of distribution, unbound drug brain : blood distribution ratio (K(p,uu)) and unbound drug volume of distribution in brain (V(u,brain)) were estimated. Key results Morphine K(p,uu) was 1.19 and 1.89 for the sheep and premature lambs, respectively, indicating that active influx into the brain decreases with age. Induced asphyxia did not affect transport of morphine or M3G across the BBB. Morphine V(u,brain) measurements were higher in sheep than in premature lambs. The M3G K(p,uu) values were 0.27 and 0.17 in sheep and premature lambs, indicating a net efflux from the brain in both groups. Conclusions and implications The morphine K(p,uu) was above unity, indicating active transport into the brain; influx was significantly higher in premature lambs than in adult sheep. These results in sheep differ from those in humans, rats, mice and pigs where a net efflux of morphine from the brain is observed.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: There is a lack of consensus around the definition of delivery by cesarean section (CS) on maternal request, and clinical practice varies across and within countries. Previous economic evaluations have focused on specific populations and selected complications. Our aim was to evaluate the cost-effectiveness of CS on maternal request compared with planned vaginal birth in a Swedish context, based on a systematic review of benefits and drawbacks and national registry data on costs.Methods: We used the results from a systematic literature review of somatic risks for long-and short-term complications for mother and child, in which certainty was rated low, moderate, or high using the Grading of Recommendations Assessment, Development and Evaluation. Swedish national registry data were used for healthcare costs of delivery and complications. Utilities for long-term complications were based on a focused literature review. We constructed a decision tree and conducted separate analyses for primi-and multiparous women. Costs and effects were discounted by 3% and the time horizon was varied between 1 and 20 years.Results: Planned vaginal birth leads to lower healthcare costs and somatic health gains compared with elective CS without medical indication over up to 20 years. Although there is uncertainty around, for example, quality-of-life effects, results remain stable across sensitivity analyses.Conclusions: CS on maternal request leads to increased hospitalization costs in a Swedish setting, taking into account short -and long-term consequences for both mother and child. Future research needs to study the psychological consequences related to different delivery methods, costs in outpatient care, and productivity losses.

- Aim: The hormone osteocalcin influenced neurodevelopment and cognition in mice models; this human study explored potential associations between total serum levels in human infants and neurodevelopment at 4years of age. Methods: The data were based on two Swedish birth cohorts from 2008 to 2009. We followed 158healthy full-term vaginal births (51% girls) by measuring serum osteocalcin in cord blood and at 4, 12 and 36months. The values were compared with neurodevelopment tests at 4years of age. Results: There was an association between osteocalcin at 4months and later full-scale intelligence quotient (IQ; r2 0.031, p<0.05). Children with osteocalcin levels in the highest quartile scored 5.6 (95% confidence interval [1.3, 9.9]) points higher than those in the lowest quartile, with mean scores of 118.8±8.8 and 113.2±9.2 (p<0.05). They also scored higher on gross motor skills (p<0.05) and showed greater ability during the drawing trail test (p<0.005). Cord levels of osteocalcin were negatively associated with processing speed and fine motor development at 4years, but levels at 12 and 36months were not associated with later neurodevelopment. Conclusion: Osteocalcin levels in infancy appeared to be associated with later IQ and motor development, but more research is needed.
