RESUMO
AIM: The protective effects of Kangaroo mother care (KMC) on the neurodevelopment of preterm infants are well established, but we do not know whether the benefits persist beyond infancy. Our aim was to determine whether providing KMC in infancy affected brain volumes in young adulthood. METHOD: Standardised cognitive, memory and motor skills tests were used to determine the brain volumes of 20-year-old adults who had formed part of a randomised controlled trial of KMC versus incubator care. Multivariate analysis of brain volumes was conducted according to KMC exposure. RESULTS: The study comprised 178 adults born preterm: 97 had received KMC and 81 were incubator care controls. Bivariate analysis showed larger volumes of total grey matter, basal nuclei and cerebellum in those who had received KMC, and the white matter was better organised. This means that the volumes of the main brain structures associated with intelligence, attention, memory and coordination were larger in the KMC group. Multivariate lineal regression analysis demonstrated the direct relationship between brain volumes and duration of KMC, after controlling for potential confounders. CONCLUSION: Our findings suggest that the neuroprotective effects of KMC for preterm infants persisted beyond childhood and improved their lifetime functionality and quality of life.

AIM: Evaluation of early growth in preterm infants receiving kinesthetic stimulation with massage in Kangaroo position or in incubator. METHODS: A cohort of 66 infants between 30 and 33 weeks of gestational age (GA), born at a university hospital in 2013 in Bogota, were randomised when eligible to intervention. We measured weight gain (g/kg/day) at five days and 15 days postrandomisation and weight at 40 weeks, according to chronological age at randomisation. RESULTS: Daily weight gain was significantly higher (p = 0.02) with kinesthetic stimulation in Kangaroo position with a growth at five days of 11.0 g/kg/day (95% CI 5.7;16.3) and at 15 days of 12.1 g/kg/day (95% CI 10.4;13.7) versus 2.1 g/kg/day (95% CI -3.1;7.4) at five days and 9.4 g/kg/day (95% CI 7.7;11.1) at 15 days in incubator. Weight at 40 weeks was higher (p = 0.05) in Kangaroo position group (2.904 g) than in incubator group (2.722 g) (95% CI 2.784;3.007). Daily weight gain according to chronological age at randomisation was higher when kinesthetic stimulation initiates before five days of life in Kangaroo position with 1.53 g/kg/day (95% CI 5.9;9.0) versus -11.9 g/kg/day (95% CI -19.0;-4.8) in incubator. CONCLUSION: Early kinesthetic stimulation in Kangaroo position reduces the initial weight loss in infants between 30-33 weeks born without major health problems.

AIM: Premature birth is an extremely stressful experience. In 2013 to 2014, we explored the physiological stress responses of fathers during their first skin-to-skin contact (SSC) with their new baby. METHODS: We recruited 49 fathers whose partners had given birth to a premature baby of up to 33 weeks and three days. The study, in the neonatal intensive care unit (NICU) of a Quebec hospital, measured the physiological stress responses of the fathers before and after they first experienced SSC with their new baby. Cortisol levels and blood pressure were measured, and a generalised estimating equation was used for the data analysis. RESULTS: The fathers' cortisol levels decreased from 10.55 nmol/L, with a 95% confidence interval (95% CI) of 9.61-11.59 at the beginning of the experiment to 8.26 nmol/L (95% CI: 7.51-9.07) after 75 minutes. Meanwhile, their systolic blood pressure decreased from 135.16 mmHg (95% CI: 130-140) to 125.25 mmHg (95% CI: 121-129). CONCLUSION: Fathers who held their baby in SSC for the first time showed a significant reduction in physiological stress responses. Our findings support hospital practices that enable fathers to experience their first intimate contact with their newborn infant in the NICU.

BACKGROUND AND OBJECTIVES: Kangaroo mother care (KMC) is a multifaceted intervention for preterm and low birth weight infants and their parents. Short- and mid-term benefits of KMC on survival, neurodevelopment, breastfeeding, and the quality of mother-infant bonding were documented in a randomized controlled trial (RCT) conducted in Colombia from 1993 to 1996. The aim of the present study was to evaluate the persistence of these results in young adulthood. METHODS: From 2012 to 2014, a total of 494 (69%) of the 716 participants of the original RCT known to be alive were identified; 441 (62% of the participants in the original RCT) were re-enrolled, and results for the 264 participants weighing ≤1800 g at birth were analyzed. The KMC and control groups were compared for health status and neurologic, cognitive, and social functioning with the use of neuroimaging, neurophysiological, and behavioral tests. RESULTS: The effects of KMC at 1 year on IQ and home environment were still present 20 years later in the most fragile individuals, and KMC parents were more protective and nurturing, reflected by reduced school absenteeism and reduced hyperactivity, aggressiveness, externalization, and socio-deviant conduct of young adults. Neuroimaging showed larger volume of the left caudate nucleus in the KMC group. CONCLUSIONS: This study indicates that KMC had significant, long-lasting social and behavioral protective effects 20 years after the intervention. Coverage with this efficient and scientifically based health care intervention should be extended to the 18 million infants born each year who are candidates for the method.

UNLABELLED: The components of the Kangaroo Mother Care (KMC) intervention, their rational bases, and their current uses in low-, middle-, and high-income countries are described. KMC was started in 1978 in Bogotá (Colombia) in response to overcrowding and insufficient resources in neonatal intensive care units associated with high morbidity and mortality among low-birthweight infants. The intervention consists of continuous skin-to-skin contact between the mother and the infant, exclusive breastfeeding, and early home discharge in the kangaroo position. In studies of the physiological effects of KMC, the results for most variables were within clinically acceptable ranges or the same as those for premature infants under other forms of care. Body temperature and weight gain are significantly increased, and a meta-analysis showed that the kangaroo position increases the uptake and duration of breastfeeding. Investigations of the behavioral effects of KMC show rapid quiescence. The psychosocial effects of KMC include reduced stress, enhancement of mother-infant bonding, and positive effects on the family environment and the infant's cognitive development. CONCLUSION: Past and current research has clarified some of the rational bases of KMC and has provided evidence for its effectiveness and safety, although more research is needed to clearly define the effectiveness of the various components of the intervention in different settings and for different therapeutic goals.
