- 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 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.

- 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).

- Objectives: To examine parental participation in the care of newborn infants receiving therapeutic hypothermia, and to explore the possible impact of in-born vs out-born status, and location of hospital accommodation. Study design: Retrospective, quantitative and descriptive design. Main outcome measures: Infants medical charts were reviewed for defined aspects of parental participation (infant holding, tube feeding, and diaper change), and related to their in-born vs out-born status, and whether the parents were accommodated in the NICU or elsewhere. All infants have been cared for at the University Hospital Neonatal Intensive Care Unit, serving as a regional referral center for hypothermia treatment. This study is a part of a population-based regional cohort of asphyxiated newborn infants (n = 112) that received therapeutic hypothermia in 2007-2015. Results: Parents engaged in holding (60/112, 54%) or tube feeding (59/112, 53%) their infant. Parents of inborn infants (24/112, 21%) were more likely to check the placement of the feeding tube (11/24, 46% vs 15/88, 17%; p < 0.01) and change diapers (9/24, 38% vs 14/88, 16%; p < 0.05) than parents of out-born infants (88/112, 79%). A similar pattern of more extensive involvement was observed for both mothers and fathers who stayed at the neonatal intensive care compared to those accommodated elsewhere (p < 0.05). Conclusions: Active parental participation is feasible at the NICU even during therapeutic hypothermia. Timely postnatal transfer of parents of out-born/transported infants, and the provision of on-site accommodation may influence the quality of parental involvement.

- Aim: This study aimed to explain the relationship between visual-motor integration (VMI) abilities and extremely preterm (EPT) birth, by exploring the influence of perinatal variables, cognition, manual dexterity and ophthalmological outcomes. Methods: This was part of the population-based national Extremely Preterm Infant Study in Sweden (EXPRESS) study. We studied 355 children, born at a gestational age of <27 weeks from April 2004 to March 2007, and 364 term-born controls. At six-and-a-half years of age, we assessed VMI, cognitive function, motor skills and vision. VMI impairment was classified as <-1 standard deviation (SD). Results: The mean (SD) VMI score was 87 (+/- 12) in preterm children compared to 98 (+/- 11) in controls (p < 0.001). VMI impairment was present in 55% of preterm infants and in 78% of children born at 22-23 weeks. Male sex and postnatal steroids showed a weak association with poorer visual-motor performance, whereas low manual dexterity and cognitive function showed a stronger association. Conclusion: Poor VMI performance was common in this EXPRESS cohort of children born EPT. Its strong association to cognition and manual dexterity confirms that all of these factors need to be taken into account when evaluating risks in preterm born children.

- Breastfeeding is challenging for mothers of preterm infants. The aim of this paper is to describe risk factors for ceasing breastfeeding and methods of feeding until 12 months postnatal age in mothers who breastfed their preterm infants at discharge from neonatal intensive care units (NICUs). The data come from a randomised controlled trial, which evaluated the effectiveness on exclusive breastfeeding at 8 weeks of proactive telephone support compared with reactive support offered to mothers of preterm infants following discharge from NICU. Six NICUs across Sweden randomised a total of 493 mothers. We used regression and survival analyses to assess the risk factors for ceasing breastfeeding and the long-term outcomes of the intervention. The results showed that 305 (64%) of the infants were breastfed at 6 months and 49 (21%) at 12 months. Partial breastfeeding at discharge, low maternal educational level, and longer length of stay in the NICU increased the risk for ceasing breastfeeding during the first 12 months. Furthermore, the Kaplan-Meier analysis showed that the proportion of mothers who ceased breastfeeding did not differ between the intervention (n = 231) and controls (n = 262) during the first 12 months (log-rank test p = .68). No difference was found between groups on method of feeding. More than 85% of the infants were fed directly at the breast. These findings provide important insights for health professionals who are supporting mothers of preterm infants to breastfeed long term.Registered in www.clinicaltrials.gov (NCT01806480).

Breastfeeding duration in preterm infants and the effects of a proactive telephone support: a randomized controlled trial
- 2018
-
Konferensbidrag (refereegranskat)abstract
- IntroductionThe first months at home may be troublesome for mothers of preterm infants (< 37 gestational weeks) due to lack of support and thereby an increased risk for ceasing breastfeeding (Kair, Flaherman, Newby, & Colaizy, 2015; Niela-Vilen, Axelin, Melender, & Salantera, 2015). Breastfeeding prevalence in preterm infants is lower than in term infants and decreases during the first months at home (Akerstrom, Asplund, & Norman, 2007; Flacking, Nyqvist, Ewald, & Wallin, 2003). The aim of this trial was to evaluate the effects of a proactive breastfeeding telephone support to mothers of preterm infants on breastfeeding, method of feeding and to describe breastfeeding duration and risks for ceasing breastfeeding up to one year of infant age. MethodThis is a multicentre randomized controlled trial with six neonatal units in Sweden participated. At each unit a breastfeeding support team, BST (10 staff/unit) recruited, randomized and delivered the telephone support to eligible and participating mothers. The intervention was a proactive telephone call initiated by the BST day 1-14 after discharge from the neonatal unit. In the control group, the mothers received a telephone number to the BST if they wanted to call and ask or talk about anything. The outcomes reported were breastfeeding, method of feeding, duration of and risks for ceasing breastfeeding. All researchers were blind to group allocation throughout the study period. ResultsIn total 493 mothers were randomized. There were no statistical significant differences between intervention (n=231) and control (n=262) group on breastfeeding, at discharge (OR 0.70, 95% CI 0.44-1.12, p=0.09), eight weeks after discharge (OR 1.12, 95% CI 0.75-1.69, p=0.45), six months (OR 1.21, 95% CI 0.78-1.88, p=0.29) and 12 months (OR 0.87, 95% CI 0.42-1.79, p=0.52) of infant age. Not either on method of feeding. Most infants received human milk directly at the breast; few infants received human milk by bottle, cup or tube feeding. At discharge, eight weeks after discharge and six months of infant age 82%, 58% and 23% of the infants were exclusively breastfed respectively. At 12 months of infant age, 21% were partially breastfed. Partial breastfeeding at discharge (HR 1.81, 95%CI 1.35-2.41, p=<0.001) and secondary school or lower maternal educational level (HR 1.42, 95%CI 1.13-1.79, p=0.003) increased the risk for ceasing breastfeeding during the infants first year of life. A shorter length of stay in weeks reduced the risk of ceasing breastfeeding during the infants first year of life (HR 0.96, 95% CI 0.92-0.99, p=0.021). ConclusionA two-week daily proactive telephone breastfeeding support did not affect exclusive breastfeeding and method of feeding during the infants first year of life. Few infants received human milk by other method than at breast-feeding. However, partial breastfeeding at discharge from the neonatal unit, secondary school or lower maternal educational level and longer hospital stay significantly increased the risk for ceasing breastfeeding during the infants first year of life. The study gives a unique long-term follow-up on breastfeeding in preterm infants.

Breastfeeding in mothers of preterm infants : Prevalence and effects of support
- 2018

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The overall aim of this thesis was to describe the prevalence of breastfeeding in preterm infants and to evaluate the effectiveness and mother’s experiences of proactive person-centred telephone support after discharge. Furthermore, to describe the duration of breastfeeding and risks of ceasing breastfeeding up to 12 months. The first study, a register study with data from the Swedish Neonatal Quality register (SNQ), included breastfeeding data at discharge from 29 445 preterm infants born from 2004-2013. The results demonstrated that the prevalence of exclusive breastfeeding among preterm infants in Sweden decreased during the study period, especially among extremely preterm infants (<28 weeks). We also performed a multicentre randomised controlled trial (RCT) of 493 breastfeeding mothers of preterm infants discharged from six neonatal units in Sweden. The intervention consisted of a proactive breastfeeding telephone support system in which a breastfeeding support team called the mothers once everyday up to 14 days after discharge. The control group received reactive support; the mothers were invited to call the breastfeeding support team if they wanted to talk or ask any questions (i.e., usual care).The RCT demonstrated that the intervention did not affect exclusive breastfeeding at eight weeks after discharge (primary outcome) or up to 12 months. The proactive support did not affect maternal breastfeeding satisfaction, attachment, quality of life or method of feeding (secondary outcomes). However, parental stress was significantly reduced in mothers in the intervention group. Mothers in the intervention group were significantly more satisfied and involved in the support and felt empowered compared with mothers in the control group, who experienced reactive support as dual. Further findings showed that a lower maternal educational level, partial breastfeeding at discharge and longer stay in the neonatal unit increased the risk of ceasing breastfeeding during the first 12 months of postnatal age. In conclusion, the trend for exclusive breastfeeding at discharge in preterm infants is declining, which necessitates concern. The evaluated intervention of telephone support did not affect breastfeeding, in the short-or long-term. However, maternal stress was reduced and mothers were significantly more satisfied with the proactive support and felt empowered by the support.
