BACKGROUND AND OBJECTIVE: Family-centered developmentally supportive care of very low birth weight infants, provided by the Newborn Individualized Developmental Care and Assessment Program (NIDCAP) has been reported to have positive medical and economic impacts. Our aim was to investigate its effect on need of ventilatory assistance, growth, and hospitalization in a Swedish setting. METHODS: Preterm infants born between September 1994 and April 1997 with a gestational age <32 weeks and with a need of ventilatory assistance at 24 hours were randomly assigned to either NIDCAP (n = 12) or conventional care (n = 13). The 2 groups were comparable (median [range]) with respect to birth weight (1083 [630-1411] vs 840[636-1939 g]), head circumference (24.0 [22.3-26.5] vs 24.0 [21. 1-30.0 cm]), gestational age (27.6 [24.0-28.7] vs 26.1 [23.9-30.3] weeks), female/male ratio (3/9 vs 9/8) and Clinical Risk Index for Babies (4.0 [0-11] vs 6.0 [2-15]). The infants in the intervention group were cared for in a separate room by a group of specially trained nurses. Formal weekly observations of these infants starting within 3 days after birth and continuing until 36 weeks postconception were used to develop individualized care plans. These plans provided recommendations as to how care might be attuned to the current developmental stage of the infant and how the family might be supported and stimulated to participate in this care. The treatment of the 2 groups was in all other respects identical. RESULTS: The duration of mechanical ventilation (median [range] was 2.8 [0-36.7] days in the intervention group vs 4.8 [.1-29.8] days; not significant [NS]) among the controls and continuous positive airway pressure was applied for 26.1 (6.9-52.0) vs 43.9 (5.0-65.1) days. Supplementary oxygen was withdrawn at 33.0 (29.3-35.7) vs 38.1 (33.1-44.9) weeks of postconceptional age (PCA). The weight gain up to 35 weeks of PCA was 13.0 (6.7-21.0) vs 9.8 (6.8-16.6) g/day (NS). The head growth up to 35 weeks of PCA was.73 (.56-1.3) vs.63 (.56-. 77) cm/week (NS). The age of the infant at discharge was 38.3 (36. 1-57.7) vs 41.0 (36.9-48.4) weeks of PCA (NS). CONCLUSIONS: NIDCAP does not seem to have detrimental effects on Swedish very low birth weight infants in comparison with conventional care. Indeed, NIDCAP might even be advantageous.

Aim: To determine whether a strength-based home-visiting program enhances parent-child interaction during the first year at home for children born extremely preterm (gestational age < 28)., Methods: A randomised controlled trial of 130 infants born extremely preterm 2018-2021 in Stockholm, allocated to either the Stockholm preterm interaction-based intervention (SPIBI) (n = 66) or an extended follow-up program (n = 64). The intervention group received ten home visits during the first year by a trained interventionist following SPIBI guidelines: an interaction-based intervention supporting sensitive parental responses to infants' signals. The primary outcome of emotional availability was assessed at 12 months corrected age (CA) using the emotional availability scales (EAS)., Results: At 1-year CA, data were collected from 115/130 (89%) of the included children. There were no significant group differences in emotional availability at 12 months CA. A secondary analysis showed an effect modifier in families with mothers self-rated as depressed at discharge, with the outcome favouring intervention in the EAS dimension of child involvement., Conclusion: The SPIBI had no significant main effect on emotional availability at 12 months CA. Children of self-reported depressed mothers displayed superior involvement behaviour in the intervention group, prompting further research on risk groups and potential modifications of post-discharge interventions., (© 2024 The Author(s).

Mother-Newborn Couplet Care is a concept and is defined as the provision of care for a sick or preterm newborn in close proximity to and coupled with the care for the mother from the birth of the infant and for as long as the mother needs hospital care. This concept of care requires system change in both obstetrics and pediatrics in terms of the planning and organization of care, equipment and design of units. Accordingly, strong leadership setting clear goals and emphasizing a culture of cohesive care, supported by targeted education and training is crucial to ensure high-quality care of all mother-newborn dyads without separation. We describe various organizational models of Mother-Newborn Couplet Care used in Sweden and Finland and implementation processes. We envision a future where newborns and mothers are always together, irrespective of medical needs, and form an inseparable center around which healthcare services and providers are organized., (© 2023.

Background: To implement the immediate Kangaroo mother care (iKMC) intervention in the previous multicentre, open-label, randomised controlled trial, the mother or a surrogate caregiver and neonate needed to be together continuously, which led to the concept of the Mother-Newborn Care Unit (MNCU). Health-care providers and administrators were concerned of the potential increase in infections caused by the continuous presence of mothers or surrogates in the MNCU. We aimed to assess the incidence of neonatal sepsis in sub-groups and the bacterial profile among intervention and control neonates in the study population., Methods: This is a post-hoc analysis of the previous iKMC trial, which was conducted in five level 2 Newborn Intensive Care Units (NICUs) one each in Ghana, India, Malawi, Nigeria, and Tanzania, in neonates with birth weight 1 to <1.8 kg. The intervention was KMC initiated immediately after birth and continued until discharge and compared to conventional care with KMC initiated after meeting stability criteria. The primary outcomes of this report were the incidence of neonatal sepsis in sub-groups, sepsis-related mortality and bacterial profile of isolates during hospital stay. The original trial is registered with the Australia and New Zealand Clinical Trials Registry (ACTRN12618001880235) and the Clinical Trials Registry-India (CTRI/2018/08/01536)., Findings: Between November 30, 2017, and January 20, 2020, 1609 newborns in the intervention group and in the control group 1602 newborns were enrolled in iKMC study. 1575 newborns in the intervention group and 1561 in the control group were clinically evaluated for sepsis. Suspected sepsis was 14% lower in intervention group in sub-group of neonates with birth weight 1.0-<1.5 kg; RR 0.86 (CI 0.75, 0.99). Among neonates with birth weight 1.5-<1.8 kg, suspected sepsis was reduced by 24%; RR 0.76 (CI 0.62, 0.93). Suspected sepsis rates were lower in intervention group than in the control group across all sites. Sepsis related mortality was 37% less in intervention group than the control group; RR 0.63 (CI 0.47-0.85) which was statistically significant. The intervention group had fewer cases of Gram-negative isolates (n = 9) than Gram positive isolates (n = 16). The control group had more cases of Gram-negative isolates (n = 18) than Gram positive (n = 12)., Interpretation: Immediate Kangaroo Mother care is an effective intervention to prevent neonatal sepsis and sepsis related mortality., Funding: The original trial was funded by the Bill and Melinda Gates Foundation through a grant to the World Health Organization (grant No. OPP1151718)., Competing Interests: All authors declare no competing interests., (© 2023 The Authors.)

Aim: To investigate the impact of immediate skin-to-skin contact with a parent after birth on thermal regulation in very preterm infants., Methods: This clinical trial was conducted in three neonatal intensive care units in Scandinavia from 2018 to 2021. Infants born between 28 + 0 and 32 + 6 weeks and days of gestation were randomised to immediate skin-to-skin contact or conventional care in an incubator during the first 6 postnatal hours. We report on a secondary outcome: serial measurements of axillary temperature., Results: Ninety-one infants were randomised to skin-to-skin contact or conventional care. Mean (range) gestational ages were 31 + 2 (28 + 6, 32 + 5) and 31 + 0 (28 + 4, 32 + 6) weeks and days, mean birth weights were 1572 (702, 2352) and 1495 (555, 2440) grams, respectively. Mean (95%CI, p-value) temperatures were within the normal range in both groups, 0.2°C (-0.29, -0.14, p < 0.001) lower in the skin-to-skin contact group. The skin-to-skin contact group had a lower relative risk (95%CI, p-value) of developing events of hyperthermia, RR = 0.70 (0.50, 0.99, p = 0.04)., Conclusions: Very preterm infants, irrespective of clinical stability, do not develop hypothermia during immediate skin-to-skin contact after birth. Immediate skin-to-skin contact did protect against events of hyperthermia. Concerns about thermal regulation should not limit implementation of immediate skin-to-skin contact in high-resource settings., (© 2022 The Authors.

Aim: To investigate the safety of skin-to-skin contact initiated immediately after birth on cardiorespiratory parameters in unstable low birth weight infants., Methods: A randomized clinical trial was conducted in tertiary newborn units in Ghana, India, Malawi, Nigeria and Tanzania in 2017-2020, in infants with birth weight 1.0-1.799 kg. The intervention was Kangaroo mother care initiated immediately after birth and continued until discharge compared to conventional care with Kangaroo mother care initiated after meeting stability criteria. The results of the primary study showed that immediate Kangaroo mother care reduced neonatal mortality by 25% and the results have been published previously. The post-hoc outcomes of this study were mean heart rate, respiratory rate, oxygen saturation during the first four days and the need of respiratory support., Results: 1,602 infants were allocated to control and 1,609 to intervention. Mean birth weight was 1.5 kg (SD 0.2) and mean gestational age was 32.6 weeks (SD 2.9) . Infants in the control group had a mean heart rate 1.4 beats per minute higher (95% CI -0.3-3.1, p  = 0.097), a mean respiratory rate 0.4 breaths per minute higher (-0.7-1.5, p  = 0.48) and a mean oxygen saturation 0.3% higher (95% CI -0.1-0.7, p  = 0.14) than infants in the intervention group., Conclusion: There were no significant differences in cardiorespiratory parameters during the first four postnatal days. Skin-to-skin contact starting immediately after birth is safe in low birth weight infants in limited-resource settings., Competing Interests: The authors report no conflicts of interest to declare., (.)

Aim: Our aim was to investigate what effect immediate skin-to-skin contact with a parent had on the cardiorespiratory stabilisation of very preterm infants., Methods: This randomised clinical trial was conducted during 2018-2021 at two university hospitals with three neonatal intensive care units in Norway and Sweden. Infants born from 28+0 to 32+6 weeks of gestation were randomised to immediate skin-to-skin contact with a parent for the first six postnatal hours or standard incubator care. The outcome was a composite cardiorespiratory stability score, based on serial measures of heart and respiratory rate, respiratory support, fraction of inspired oxygen and oxygen saturation., Results: We recruited 91 newborn infants with a mean gestational age of 31+1 (range 28+4-32+6) weeks and mean birth weight of 1534 (range 555-2440) g: 46 received immediate skin-to-skin contact and 45 received incubator care. The group who received skin-to-skin contact had an adjusted mean score of 0.52 higher (95% confidence interval 0.38-0.67, p < 0.001) on a scale from zero to six when compared to the control group., Conclusion: Immediate skin-to-skin contact for the first six postnatal hours had beneficial effects on the cardiorespiratory stabilisation of very preterm infants., (© 2022 Foundation Acta Paediatrica.

With an increasing awareness of the importance of nurturing care and within a framework of Infant- and Family-Centred Developmental Care (IFCDC), zero separation, keeping parent and infant in continuous close physical and psychological proximity to each other, is key. In modern neonatology, high technological and pharmaceutical treatments are consistently integrated with caregiving considerations. Mother-Newborn Couplet Care is a concept of care where the dyad of the ill or prematurely born infant and the mother, needing medical care of her own, are cared for together, from the birth of the baby to its discharge. Mother-Newborn Couplet Care requires systems changes in both obstetrics and paediatrics considering planning and organisation of care, equipment and design of units. Accordingly, strong leadership setting clear goals and changing the professional mindset by providing targeted education and training is crucial to ensure the warranted high quality of care of all mother-baby dyads., (© 2021 The Authors.

Background: "Kangaroo mother care," a type of newborn care involving skin-to-skin contact with the mother or other caregiver, reduces mortality in infants with low birth weight (<2.0 kg) when initiated after stabilization, but the majority of deaths occur before stabilization. The safety and efficacy of kangaroo mother care initiated soon after birth among infants with low birth weight are uncertain., Methods: We conducted a randomized, controlled trial in five hospitals in Ghana, India, Malawi, Nigeria, and Tanzania involving infants with a birth weight between 1.0 and 1.799 kg who were assigned to receive immediate kangaroo mother care (intervention) or conventional care in an incubator or a radiant warmer until their condition stabilized and kangaroo mother care thereafter (control). The primary outcomes were death in the neonatal period (the first 28 days of life) and in the first 72 hours of life., Results: A total of 3211 infants and their mothers were randomly assigned to the intervention group (1609 infants with their mothers) or the control group (1602 infants with their mothers). The median daily duration of skin-to-skin contact in the neonatal intensive care unit was 16.9 hours (interquartile range, 13.0 to 19.7) in the intervention group and 1.5 hours (interquartile range, 0.3 to 3.3) in the control group. Neonatal death occurred in the first 28 days in 191 infants in the intervention group (12.0%) and in 249 infants in the control group (15.7%) (relative risk of death, 0.75; 95% confidence interval [CI], 0.64 to 0.89; P = 0.001); neonatal death in the first 72 hours of life occurred in 74 infants in the intervention group (4.6%) and in 92 infants in the control group (5.8%) (relative risk of death, 0.77; 95% CI, 0.58 to 1.04; P = 0.09). The trial was stopped early on the recommendation of the data and safety monitoring board owing to the finding of reduced mortality among infants receiving immediate kangaroo mother care., Conclusions: Among infants with a birth weight between 1.0 and 1.799 kg, those who received immediate kangaroo mother care had lower mortality at 28 days than those who received conventional care with kangaroo mother care initiated after stabilization; the between-group difference favoring immediate kangaroo mother care at 72 hours was not significant.

With increasing survival rates of children born extremely preterm (EPT), before gestational week 28, the post-discharge life of these families has gained significant research interest. Quantitative studies of parental experiences post-discharge have previously reported elevated levels depressive symptoms, posttraumatic stress-disorder and anxiety among the parents. The current investigation aims to qualitatively explore the situation for parents of children born EPT in Sweden during the first year at home. Semi-structured interviews were performed with 17 parents of 14 children born EPT; eight parents were from an early intervention group and nine parents from a group that received treatment as usual, with extended follow-up procedures. Three main themes were identified using a thematic analytic approach: child-related concerns, the inner state of the parent, and changed family dynamics. Parents in the intervention group also expressed themes related to the intervention, as a sense of security and knowledgeable interventionists. The results are discussed in relation to different concepts of health, parent-child interaction and attachment, and models of the recovery processes. In conclusion, parents describe the first year at home as a time of prolonged parental worries for the child as well as concerns regarding the parent's own emotional state.

Introduction: In Scandinavia, 6% of infants are born preterm, before 37 gestational weeks. Instead of continuing in the in-utero environment, maturation needs to occur in a neonatal unit with support of vital functions, separated from the mother's warmth, nutrition and other benefits. Preterm infants face health and neurodevelopment challenges that may also affect the family and society at large. There is evidence of benefit from immediate and continued skin-to-skin contact (SSC) for term and moderately preterm infants and their parents but there is a knowledge gap on its effect on unstable very preterm infants when initiated immediately after birth., Methods and Analysis: In this ongoing randomised controlled trial from Stavanger, Norway and Stockholm, Sweden, we are studying 150 infants born at 28+0 to 32+6 gestational weeks, randomised to receive care immediately after birth in SSC with a parent or conventionally in an incubator. The primary outcome is cardiorespiratory stability according to the stability of the cardiorespiratory system in the preterm score. Secondary outcomes are autonomic stability, thermal control, infection control, SSC time, breastfeeding and growth, epigenetic profile, microbiome profile, infant behaviour, stress resilience, sleep integrity, cortical maturation, neurodevelopment, mother-infant attachment and attunement, and parent experience and mental health., Ethics and Dissemination: The study has ethical approval from the Swedish Ethical Review Authority (2017/1135-31/3, 2019-03361) and the Norwegian Regional Ethical Committee (2015/889). The study is conducted according to good clinical practice and the Helsinki declaration. The results of the study will increase the knowledge about the mechanisms behind the effects of SSC for very preterm infants by dissemination to the scientific community through articles and at conferences, and to the society through parenting classes and magazines., Study Status: Recruiting since April 2018.

Aim: Current care of very preterm infants in an incubator implies separation of the mother-infant dyad. The aim of this study was to determine whether skin-to-skin contact (SSC) between parent and very preterm infant from birth and during the first postnatal hour is feasible., Methods: Infants born in 2014-16 in Stockholm at gestational age 28 + 0-33 + 6 weeks were randomised to care provided in SSC with a parent or on a resuscitaire and later in an incubator or bed during the first postnatal hour. Infant body temperature was measured on admission to the neonatal unit and at one postnatal hour. Data on respiratory support and breastfeeding were prospectively collected., Results: We studied 55 infants at 32 + 0 ± 1.4 weeks (range 28 + 2-33 + 6), with birthweight 1760 g ± 449 g (range 885-2822). 60% were boys. Mean body temperature in the SSC group was 0.3°C lower 1 hour after birth, 36.3°C ± 0.52 (range 34.4-37.2) vs 36.6°C ± 0.42 (range 36.0-37.4, P = .03). No differences between groups were seen in respiratory support or breastfeeding., Conclusion: Stabilisation of very preterm infants can be performed while in SSC with a parent, but caution needs to be paid to maintain normothermia., (© 2019 Foundation Acta Paediatrica.

Background: Improved neonatal care has resulted in increased survival rates among infants born after only 22 gestational weeks, but extremely preterm children still have an increased risk of neurodevelopmental delays, learning disabilities and reduced cognitive capacity, particularly executive function deficits. Parent-child interaction and parental mental health are associated with infant development, regardless of preterm birth. There is a need for further early interventions directed towards extremely preterm (EPT) children as well as their parents. The purpose of this paper is to describe the Stockholm Preterm Interaction-Based Intervention (SPIBI), the arrangements of the SPIBI trial and the chosen outcome measurements., Methods: The SPIBI is a randomized clinical trial that includes EPT infants and their parents upon discharge from four neonatal units in Stockholm, Sweden. Inclusion criteria are EPT infants soon to be discharged from a neonatal intensive care unit (NICU), with parents speaking Swedish or English. Both groups receive three initial visits at the neonatal unit before discharge during the recruitment process, with a strengths-based and development-supportive approach. The intervention group receives ten home visits and two telephone calls during the first year from a trained interventionist from a multi-professional team. The SPIBI intervention is a strengths-based early intervention programme focusing on parental sensitivity to infant cues, enhancing positive parent-child interaction, improving self-regulating skills and supporting the infant's next small developmental step through a scaffolding process and parent-infant co-regulation. The control group receives standard follow-up and care plus extended assessment. The outcomes of interest are parent-child interaction, child development, parental mental health and preschool teacher evaluation of child participation, with assessments at 3, 12, 24 and 36 months corrected age (CA). The primary outcome is emotional availability at 12 months CA., Discussion: If the SPIBI shows positive results, it could be considered for clinical implementation for child-support, ethical and health-economic purposes. Regardless of the outcome, the trial will provide valuable information about extremely preterm children and their parents during infancy and toddlerhood after regional hospital care in Sweden., Trial Registration: The study was registered in ClinicalTrials.gov in October 2018 (NCT03714633).

Advances in neonatal care have improved survival of premature and critically ill infants; and while rates of some long-term neurodevelopmental problems in survivors have improved, such as cerebral palsy, there are others such as learning and behavioural difficulties that have not. The goal of improving long term neurodevelopmental morbidity has led to an increased focus on improving developmental care not only in neonatal long term follow- up clinics but within the NICU itself to capture the period of earliest brain neuroplasticity. The application of a systematic approach to improve practice is considered the most effective strategy for implementing neuroprotective developmentally supportive care. The content of this paper incorporates evidence-based systematic reviews to guide clinicians in the application of developmentally supportive interventions., (Crown Copyright © 2019.

Behavioral and emotional outcomes for babies who experienced maternal separation due to prematurity or birth defects have not improved significantly for the last 20 years. Current theories and treatment paradigms based on neuroscience have not generated explanatory mechanisms that work, or provided testable hypotheses. This article proposes a new field of scientific investigation, "nurturescience" within which new hypotheses can be tested with novel instruments. Key distinctions between neuroscience and nurturescience are described. Our definition of nurturescience is based on the basic needs of all newborns and of the needs of mothers and their families. This understanding is drawn from biology, anthropology, sociology, physiological, and clinical research. Mechanisms are described from studies on microbiota, epigenetics, allostasis, brain imaging, and developmental origins of health and adult disease. The converging message from these and other fields is that the mother-infant dyad should not be separated. Ongoing emotional connection is the cornerstone of development, leading to life-long resilience. This has implications for making the correct diagnosis (emotional disconnection vs. attachment disorder), providing the appropriate care (infant and family centered developmental care) in the biologically expected place (skin-to-skin contact), and potential for rehabilitation (calming cycle theory). Nurturescience has particular relevance to the care of "small and sick" infants, with profound potential for decreasing the "likelihood of developing developmental problems.", (© 2019 Wiley Periodicals, Inc.)

Introduction: Low birth weight (LBW, <2500 g) may predict an increased risk of an adverse cardiometabolic profile later in life, but long-term effects in different populations and birth weight strata are still unclear. We explored laboratory markers of cardiometabolic risk in children born with marginally LBW (2000-2500 g)., Methods: This was a prospective longitudinal cohort study including 285 Swedish marginally LBW children and 95 normal birth weight (NBW, 2501-4500 g) controls. At 3.5 and 7 years of age, blood samples for glucose, insulin, homeostatic model assessment for insulin resistance (HOMA-IR), cholesterol, triglycerides, high- and low density lipoprotein (HDL and LDL), apolipoprotein B (ApoB) and apolipoprotein A1 (ApoA1) were assessed and compared between the groups., Results: No significant differences in levels of insulin, HOMA-IR, hs-CRP or blood lipids were observed between marginally LBW and NBW children. At 7 years there was a higher proportion of marginally LBW children with elevated levels of insulin, defined as above the 90th percentile of the control group (21% vs 8.6%, p = 0.038). This association was, however, confounded by maternal ethnicity. In marginally LBW children born small for gestational age (SGA), mean fasting glucose was significantly higher compared to controls (4.7 vs 4.5 mmol/L, p = 0.020)., Conclusions: There were no significant differences in insulin, insulin resistance, hs-CRP or blood lipids between the marginally LBW children and controls. The subgroup of marginally LBW children born SGA may present early signs of glucose imbalance already at school age., Competing Interests: The authors have declared that no competing interests exist.

BackgroundBeing born with very low birth weight (<1500 g) is associated with poorer neurocognition later in life. The aim of this study was to explore neurodevelopmental functions in those born with marginally LBW (2000-2500 g).MethodsThis was originally a randomized controlled trial investigating the effects of early iron supplementation in 285 marginally LBW children. Herein, we explored the combined marginally LBW group and compared their results to 95 normal birth weight (NBW; 2501-4500 g) controls in an observational design. At 7 years, a pediatric psychologist tested the children using Wechsler Intelligence Scale for Children (WISC IV), Beery-Buktenica developmental test of Visual-Motor Integration (Beery VMI), and Test of Everyday Attention for Children (TEA-Ch).ResultsThe marginally LBW children had lower verbal comprehension intelligence quotient (IQ) (104 vs. 107, P=0.004), lower VMI scores (96.5 vs. 100, P=0.028), and lower total mean TEA-Ch scores (8.5 vs. 9.7, P=0.006), compared to controls. Also, the marginally LBW children group had a higher proportion of children below -1 SD for VMI and TEA-Ch.ConclusionsMarginally LBW children had lower verbal comprehension IQ, lower visual-motor integration, and lower attention performance than NBW children, suggesting an increased risk of cognitive difficulties in early school age.

BackgroundLow-birth-weight infants (LBW) are at an increased risk of iron deficiency that has been associated with impaired neurodevelopment. We hypothesized that iron supplementation of LBW infants improves cognitive scores and reduces behavioral problems until school age.MethodsWe randomized 285 marginally LBW (2,000-2,500 g) infants to receive 0, 1, or 2 mg/kg/day of iron supplements from 6 weeks to 6 months of age. At 7 years of age, 205 participants were assessed regarding cognition using Wechsler Intelligence Scale for Children (WISC-IV) and behavior using the parental questionnaires Child Behavior Checklist (CBCL) and Five to Fifteen (FTF).ResultsThere were no significant differences between the intervention groups in WISC-IV or FTF. However, the CBCL scores for externalizing problems were significantly different, in favor of supplemented children (P=0.045). When combining the supplemented groups, they had significantly lower scores for externalizing behavior compared with placebo (median (interquartile range): 44 [34;51] vs. 48.5 [41;56] P=0.013), and their risk ratio (95% confidence interval) for a total behavioral score above the cutoff for clinical problems was 0.31 (0.09-1.0), P=0.054.ConclusionLower scores of externalizing behavior in supplemented children support our previous findings at 3 years, and suggest that iron supplementation may have long-lasting effects on behavioral functions.

Background: Low birth weight (LBW) (≤2500 g) is associated with iron deficiency in infancy and high blood pressure (BP) later in life. Objective: We investigated the effect of iron supplementation that was given to LBW infants on midchildhood BP. Design: The study was a randomized, double-blind, controlled trial that included 285 marginally LBW (2000-2500-g) infants at 2 Swedish centers between May 2004 and November 2007. The infants were randomly assigned to receive a placebo or 1 or 2 mg Fe · kg -1 · d -1 from 6 wk to 6 mo of age. In secondary analyses at the age of 7 y, systolic blood pressure (SBP), diastolic blood pressure (DBP), and the prevalence of children with BP within the hypertensive range (>90th percentile) were compared between the groups. Results: BP was analyzed via intention to treat in 189 children (66%). The mean ± SD SBP was 103 ± 8.1, 101 ± 7.5, and 101 ± 7.8 mm Hg in children who had received the placebo ( n = 70), 1 mg Fe · kg -1 · d -1 ( n = 54), or 2 mg Fe · kg -1 · d -1 ( n = 65), respectively. When the iron-supplemented groups were combined in covariate-adjusted analyses, the mean SBP in LBW children who had received iron supplementation in infancy was 2.2 mm Hg (95% CI: 0.3, 4.2 mm Hg) lower than in those who were unsupplemented ( P = 0.026). Multivariate logistic regression showed that iron supplementation in infancy reduced the odds of having an SBP within the hypertensive range at 7 y of age (OR: 0.32; 95% CI: 0.11, 0.96). For DBP, there were no significant differences between the intervention groups. Conclusions: LBW children who receive iron supplementation (1 or 2 mg Fe · kg -1 · d -1 ) in infancy have lower SBP at 7 y. This (to our knowledge) novel observation suggests that the increased risk of hypertension that is observed in children and adults who are born small might be reduced with early micronutrient interventions.

Despite the recent improvements in perinatal medical care leading to an increase in survival rates, adverse neurodevelopmental outcomes occur more frequently in preterm and/or high-risk infants. Medical risk factors for neurodevelopmental delays like male gender or intrauterine growth restriction and family sociocultural characteristics have been identified. Significant data have provided evidence of the detrimental impact of overhelming environmental sensory inputs, such as pain and stress, on the developing human brain and strategies aimed at preventing this impact. These strategies, such as free parental access or sleep protection, could be considered 'principles of care'. Implementation of these principles do not require additional research due to the body of evidence.

Aim: Little is known about the amount of physical parent-infant closeness in neonatal intensive care units (NICUs), and this study explored that issue in six European countries., Methods: The parents of 328 preterm infants were recruited in 11 NICUs in Finland, Estonia, Sweden, Norway, Italy and Spain. They filled in daily diaries about how much time they spent in the NICU, in skin-to-skin contact (SSC) and holding their babies in the first two weeks of their hospitalisation., Results: The parents' NICU presence varied from a median of 3.3 (minimum 0.7-maximum 6.7) to 22.3 (18.7-24.0) hours per day (p < 0.001), SSC varied from 0.3 (0-1.4) to 6.6 (2.2-19.5) hours per day (p < 0.001) and holding varied from 0 (0-1.5) to 3.2 (0-7.4) hours per day (p < 0.001). Longer SSC was associated with singleton babies and more highly educated mothers. Holding the baby for longer was associated with gestational age. The most important factor supporting parent-infant closeness was the opportunity to stay overnight in the NICU. Having other children and the distance from home to the hospital had no impact on parent-infant closeness., Conclusion: Parents spent more time in NICUs if they could stay overnight, underlining the importance that these facilities play in establishing parent-infant closeness., (©2017 The Authors.

Aim: Little is known about the long-term health of marginally low birthweight (LBW) children. This study characterised growth among infants weighing 2000 g-2500 g and explored the prevalence and predictors of sustained growth restriction., Method: This prospective observational trial followed the weight and height of 281 Swedish marginally LBW children from birth to 3.5 years of age. Children with a standard deviation score (SDS) for body mass index or height below -2 were considered underweight and short, respectively., Results: The mean SDS for weight and height showed a rapid increase before 12-19 weeks of age. The most rapid weight gain was in infants born small for gestational age. However, at 3.5 years of age, 9.5% of the children remained underweight and 6.5% had short stature. Regression models showed that slow weight gain before 19 weeks of age was the strongest predictor for lasting underweight, while slow height gain before 19 weeks of age and male sex were associated with short stature., Conclusion: Marginally LBW infants were more likely to be underweight and have a short stature at 3.5 years of age and the absence of catch-up growth during the first five months after birth identified those at highest risk., (©2016 Foundation Acta Paediatrica.

Objectives: To assess the prevalence of overweight/obese children and to explore body composition in a Swedish cohort of preschool children born with marginally low birth weight (MLBW, ie, 2000-2500 g)., Study Design: We included 285 Swedish children with MLBW (44% small for gestational age), and 95 control children with normal birth weights. At 3.5 years and 7 years of age, we assessed anthropometrics, including the prevalence of overweight/obese children. At 7 years, dual-energy X-ray was used for body composition., Results: There were no significant differences between groups in the prevalence of overweight/obesity or in skinfold thickness; however, at 3.5 years, mean height, weight, and BMI in children with MLBW were 2.1 cm (95% CI 1.2-3.1), 1.2 kg (95% CI 0.7-1.6), and 0.47 kg/m(2) (95% CI 0.17-0.76) lower compared with controls. The corresponding mean differences also were lower in children with MLBW compared with control children at 7 years; 2.5 cm (95% CI 0.9-4.1), 1.6 kg (95% CI 0.6-2.8), and 0.48 kg/m(2) (95% CI 0.01-0.94). The differences were greater in those born small for gestational age. Dual-energy X-ray analyses showed lower fat-free mass index in MLBW infants and a similar trend in fat mass index. Within children with MLBW, BMI at 7 years correlated positively to growth velocity in infancy., Conclusion: Children with MLBW had lower BMI and did not show increased risk of overweight or obesity up to 7 years. Nevertheless, the BMI in MLBW children was positively correlated to growth-velocity in infancy., Trial Registration: Clinicaltrials.gov: NCT00558454., (Copyright © 2015 Elsevier Inc.

Objectives: Low-birth-weight (LBW) infants (<2500 g) have an increased risk of iron deficiency (ID) during their first 6 months of life. The optimal dose and duration of iron supplementation to LBW infants are, however, unknown. The objective of the present study was to investigate the long-term effect on iron status and growth in marginally LBW (2000-2500 g) infants, of iron supplements given until 6 months of life., Methods: In a randomized controlled trial, 285 healthy marginally LBW infants received 0, 1, or 2 mg · kg(-1) · day(-1) of iron supplements from 6 weeks to 6 months of age. At 12 months and 3.5 years of life we measured length, weight, head circumference, and indicators of iron status (hemoglobin, ferritin, mean corpuscular volume, and transferrin saturation) and assessed the prevalence of iron depletion, functional ID, and ID anemia., Results: At 12 months of age, there was a significant difference in ferritin between the groups (P = 0.006). Furthermore, there was a significant difference in the prevalence of iron depletion (23.7%, 10.6%, and 6.8%, respectively, in the placebo, 1-mg, and 2-mg groups, P = 0.009) and similar nonsignificant trends for functional ID and ID anemia. At 3.5 years of life there were no significant differences in iron status and the mean prevalence of iron depletion was 3.2%. Anthropometric data were not affected by the intervention., Conclusions: Iron supplements with 2 mg · kg(-1) · day(-1) until 6 months of life effectively reduces the risk of ID during the first 12 months of life and is an effective intervention for preventing early ID in marginally LBW infants.

Background: The homeostatic mechanisms of iron metabolism and erythropoiesis in infants are unclear. Infants synthesize both fetal hemoglobin (HbF) and adult hemoglobin (HbA), and it is not known how the hemoglobin switch is regulated. We hypothesized that iron supplements to infants affect the disappearance of HbF., Methods: We randomized 285 low-birth-weight infants (2,000-2,500 g) into three intervention groups receiving 0, 1, or 2 mg/kg/d of iron supplements from 6 wk to 6 mo of age. In the present secondary analysis, we analyzed iron status, total hemoglobin (Hb), and HbF fraction at 6 wk, 12 wk, and at 6 mo and calculated absolute levels of HbF., Results: We observed dose-dependent increased levels of Hb in iron-supplemented groups at 6 mo of age. However, for absolute HbF concentration, there was no similar effect of intervention. Mean (SD) HbF was 81.2 (16.8), 37.0 (13.8), and 8.1 (5.6) g/l at 6 wk, 12 wk, and 6 mo, respectively, similar in all groups. In linear regression analyses, postconceptional age turned out as the major predictor of HbF, independent of gestational age at birth., Conclusion: Our hypothesis was rejected. Instead, we confirmed a close correlation to postconceptional age, supporting a genetically programmed switch, insensitive to most environmental factors including birth.
