RESUMEN

PURPOSE: To systematically review the literature regarding the impact of prematurity on the transition of food consistencies in infants during the introduction of complementary feeding. RESEARCH STRATEGIES: Searches were conducted in the EMBASE, Latin American and Caribbean Literature in Health Sciences (LILACS), LIVIVO, PubMed/Medline, Scopus, and Web of Science databases, Google Scholar; for gray literature, searches were conducted on Open Gray, and ProQuest Dissertations & Theses databases, from August 10, 2020, onwards. SELECTION CRITERIA: "PECOS" was selected to determine inclusion criteria: Population (P): Infants; Exposure (E): Prematurity; Comparison (C): Full-term newborns; Outcomes (O): Progression of food consistencies in premature newborns with or without comparison; Study design (S): Cohort study, Case-control; Cross-sectional. DATA ANALYSIS: The methodological quality of the selected observational studies was assessed using the Meta-Analysis of Statistics Assessment and Review Instrument (MASTARI). RESULTS: A total of 3,310 articles were found, of which nine were selected for qualitative synthesis. Among the selected studies, a relationship between invasive oral interventions and feeding difficulties was observed for all assessed skills, with feeding difficulties being more frequent in infants with lower gestational age. CONCLUSION: Most studies found no significant relationship between prematurity and difficulties in the progression of food consistencies during the introduction of complementary feeding; only three studies demonstrated such a relationship.

RESUMEN

OBJECTIVE: To evaluate the pattern of eye-gaze of preterm (PT), autism spectrum disorder (ASD) and neurotypical (Ty) children. METHODS: A cross-sectional study with eight preterm (born with ≤2000 g weight), nine ASD and five Ty male children, between six and nine years old, was performed. The eye gaze was evaluated presenting a board with a couple in social interaction, and a video with four children playing with blocks, projected in a screen computer, successively, evaluating the time that the children looked at each stimulus. RESULTS: Although all the groups focus on the central social figure with no significant differences, ASD presented significant differences in time fixation of the objects (p=0.021), while premature children fixated more time in the central social interaction than in the whole scene than typical children. CONCLUSIONS: Although this study found noteworthy differences in the eye-gaze patterns among the three groups, additional research with a more extensive participant pool is necessary to validate these preliminary results.

RESUMEN

There is still very limited evidence on the effects of neonatal interventions on infant neurodevelopmental outcomes, including general movements (GMs). This research will primarily assess the effects of a sensory motor physical therapy intervention combined with kangaroo skin-to-skin contact on the GMs of hospitalized preterm newborns. Secondary outcomes include body weight, posture and muscle tone, behavioral state, length of hospital stay, and breastfeeding. This study protocol details a two-arm parallel clinical trial methodology, involving participants with a postmenstrual age of 34-35 weeks admitted to a Neonatal Intermediate Care Unit (NInCU) with poor repertoire GMs. Thirty-four participants will be randomly assigned to either the experimental group, receiving a 10-day sensory motor physical therapy associated with kangaroo skin-to-skin contact, or the control group, which will only receive kangaroo skin-to-skin contact. The study will measure GMs (primary outcome), and body weight, posture and muscle tone, behavioral state, length of hospital stay, and breastfeeding (secondary outcomes). Data collection occurs in the NInCU before and after the intervention, with follow-up measurements post discharge at 2-4 weeks and 12-15 weeks post-term. SPSS will be used for data analyses. The results will provide novel information on how sensory motor experiences may affect early neurodevelopment and clinical variables in preterm newborns.

RESUMEN

INTRODUCTION: Prechtl's method (GMA) is a test for the functional assessment of the young nervous system. It involves a global and a detailed assessment of the general movements (GMs) and has demonstrated validity. Data on the reliability of both assessments in the preterm period are scarce. This study aimed to evaluate the inter-rater reliability for the global and detailed assessments of the preterm writhing GMA. MATERIALS AND METHODS: The study participants were 69 infants born at <37 gestational weeks and admitted to the neonatal intensive care unit. They were randomly assigned to five pairs of raters. Raters assessed infants' GMs using preterm videos. Outcome variables were (a) the GMs classification (normal versus abnormal; normal versus abnormal subcategories) and (b) the general movements optimality score (GMOS), obtained through the global and detailed assessments. The Gwet's AC1 and the intraclass correlation coefficient (ICC) were calculated for the GMs classification and the GMOS, respectively. RESULTS: The global assessment presented an AC1 = 0.84 [95% CI = 0.54,1] for the GMs binary classification and an AC1 = 0.67 [95% CI = 0.38,0.89] for the GMs classification with abnormal subcategories. The detailed assessment presented an ICC = 0.72 [95% CI = 0.39,0.90] for the GMOS. CONCLUSIONS: Inter-rater reliability was high and substantial for the global assessment and good for the detailed assessment. However, the small sample size limited the precision of these estimates. Future research should involve larger samples of preterm infants to improve estimate precision. Challenging items such as assessing the neck and trunk, poor repertoire GMs, and tremulous movements may impact the preterm writhing GMA's inter-rater reliability. Therefore, ongoing training and calibration among raters is necessary. Further investigation in clinical settings can enhance our understanding of the preterm writhing GMA's reliability.

RESUMEN

INTRODUCTION: The wrapping of the newborn in an orthopedic tubular mesh, simulating a cocoon, can allow the infant to regain the feeling of security and stability experienced in the uterus given that the movement of one of the parts of the body exerts tactile and pressure variation in others. OBJECTIVE: We aimed to evaluate the influence of an orthopedic tubular mesh, simulating a cocoon, in therapeutic positioning, on the variables of the autonomous, motor, and regulatory systems of preterm newborns. METHODS: A controlled and randomized clinical trial was conducted with preterm newborns positioned in dorsal decubitus and divided into two groups: (a) cocoon - newborns covered with an orthopedic tubular mesh, and (b) control - newborns positioned according to the sector's routine and without the use of an orthopedic mesh. During the follow-up, each newborn was placed in the position for 30 min and was recorded for a total of 2 min, once at the beginning and again at the end of the observation period. Variables related to the autonomous system (heart rate, respiratory rate, and peripheral oxygen saturation), motor system (general movements), and regulatory system (Neonatal Infant Pain Scale) were evaluated before and after the intervention. The videos were evaluated by a researcher blind to the purpose of the study, and the resulting data were analyzed using SPSS. RESULTS: Of the 40 preterm newborns evaluated (32.5 ± 1.83 weeks), 21 were female, and 20 were allocated to the cocoon group. The variables related to the autonomous, motor, and regulatory systems remained unchanged following the positioning in the cocoon, as compared to the typical positioning employed in the neonatal unit. CONCLUSION: The simulation of a cocoon, utilizing an orthopedic tubular mesh, when applied to preterm newborns admitted to a neonatal intensive care unit can contribute to maintaining low levels of stress, without altering variables of the autonomous, motor, and regulatory systems.

RESUMEN

BACKGROUND: Premature newborns have a higher risk of abnormal visual development and visual impairment. OBJECTIVE: To develop a computational methodology to help assess functional vision in premature infants by tracking iris distances. METHODS: This experimental study was carried out with children up to two years old. A pattern of image capture with the visual stimulus was proposed to evaluate visual functions of vertical and horizontal visual tracking, visual field, vestibulo-ocular reflex, and fixation. The participants' visual responses were filmed to compose a dataset and develop a detection algorithm using the OpenCV library allied with FaceMesh for the detection and selection of the face, detection of specific facial points and tracking of the iris positions is done. A feasibility study was also conducted from the videos processed by the software. RESULTS: Forty-one children of different ages and diagnoses participated in the experimental study, forming a robust dataset. The software resulted in the tracking of iris positions during visual function evaluation stimuli. Furthermore, in the feasibility study, 8 children participated, divided into Pre-term and Term groups. There was no statistical difference in any visual variable analyzed in the comparison between groups. CONCLUSION: The computational methodology developed was able to track the distances traveled by the iris, and thus can be used to help assess visual function in children.

RESUMEN

Introducción. Una forma no invasiva y segura de evaluar los parámetros neurofisiológicos en recién nacidos es la evaluación de los potenciales evocados auditivos del tronco encefálico (PEAT). Objetivo. Evaluar las latencias e intervalos de ondas de los PEAT en neonatos sanos nacidos a gran altitud (Cusco, 3399 msnm). Población y métodos. Estudio transversal y prospectivo. Se incluyeron neonatos menores a 14 días de vida, dados de alta a menos de 7 días de nacidos, evaluados para determinar los valores de los PEAT a intensidades sonoras de 70 dB, 80 dB y 90 dB. Se incluyeron las variables edad gestacional, peso al nacer, tipo de parto. Se calcularon las diferencias de las medianas de las latencias e intervalos de las ondas según edad gestacional y peso al nacer. Resultados. Se evaluaron 96 neonatos (17 pretérminos). Las medianas de las latencias de las ondas I a V a 90 dB fueron las siguientes: onda I 1,56 ms; onda II 2,74 ms; onda III 4,37 ms; onda IV 5,62 ms, onda V 6,63 ms. La latencia de la onda I para 80 dB fue de 1,71 ms y para 70 dB de 1,88 ms. Los intervalos para las ondas (I-III), (III-V) y (I-V) fueron de 2,8 ms, 2,2 ms y 5,0 ms respectivamente, sin diferencias entre intensidades (p >0,05). La prematuridad y el bajo peso estuvieron asociados a latencias de la onda I más prolongadas (p <0,05). Conclusiones. Se presentan valores ajustados de latencias e intervalos de los PEAT en neonatos nacidos a gran altitud. Se identificó que, a distintas intensidades sonoras, se ven diferencias en las latencias de las ondas, pero no en los intervalos entre ondas.

Introduction. A non-invasive and safe way to assess neurophysiological parameters in newborn infants is the evaluation of brainstem auditory evoked potentials (BAEPs). Objective. To assess the latencies and wave intervals of BAEPs in healthy newborn infants born in a high-altitude area (Cusco, 3399 MASL). Population and methods. Cross-sectional and prospective study. Newborn infants younger than 14 days of age, discharged less than 7 days after birth, were assessed to determine BAEP values at intensities of 70 dB, 80 dB, and 90 dB. The study variables were gestational age, birth weight, and type of delivery. The median differences in wave latencies and intervals were estimated according to gestational age and birth weight. Results. A total of 96 newborn infants (17 preterm infants) were assessed. The median latencies of waves I­V at 90 dB were for wave I: 1.56 ms, wave II: 2,74 ms, wave III: 4.37 ms, wave IV: 5.62 ms, and wave V: 6.63 ms. The latency of wave I for 80 dB was 1.71 ms and for 70 dB, 1.88 ms. Wave intervals (I­III, III­V, I­V) were 2.8 ms, 2.2 ms, and 5.0 ms, respectively, without differences among intensities (p > 0.05). Prematurity and low birth weight were associated with a longer wave I latency (p < 0.05). Conclusions. Here we describe adjusted BAEP latency and interval values for newborn infants born at high altitude. At different sound intensities, we identified differences in wave latencies, but not in interwave intervals.

RESUMEN

BACKGROUND: Deviations occur in the neuropsychomotor development of premature infants; early interventions minimize delay motor. This study aimed to determine the effect of an interdisciplinary hospital-home intervention addressing motor development adaptation in premature infants in Colombia in comparison with traditional interventions. METHODS: This study was based on a parallel design, with two groups, namely, experimental and control. The experimental group, hospital-home intervention (HHI) performed in two settings (i.e., hospital neonatal care units and homes), and the control group, traditional intervention, (TI) performed in institutions for premature infants. The sample will be composed of 130 randomly-allocated infants, 65 in the experimental group (HHI) and 65 in the control group (TI) of moderate to late preterm infants (gestational age between 34 and 37 weeks), weighing more than or equal to 1.800 g, who are hemodynamically stable and reside in the cities of Tunja and Bogotá-Colombia recruited between 2021 and 2022. For the pre- and post-intervention assessments, the TIMPSI and the CapDMP are the instruments used to assess motor development and the degree of parents' or caregivers' knowledge about motor development. The HHI is composed of 10 intervention strategies based on stimulation of motor development, performed twice a day for 10 min for two months, in combination with calls to a mobile device, using software (Baby Motor Skills) and an instant messaging system (WhatsApp). RESULTS: This hospital-home intervention program proposes an approach focused on the motor development of premature infants, based on sensory and motor stimulation strategies, in addition to follow-up performed at home with the use of a mobile application that improves the motor development of premature infants. Register Clinical Trial: NCT04563364. CONCLUSION: The HHI provides the opportunity to determine whether the individualized four-week from admission to follow up at home with parent training will improve the motor skills of premature infants.

RESUMEN

OBJECTIVE: To assess the hemodynamic safety and efficacy of umbilical cord milking (UCM) compared with early cord clamping (ECC) in nonvigorous newborn infants enrolled in a large multicenter randomized cluster-crossover trial. STUDY DESIGN: Two hundred twenty-seven nonvigorous term or near-term infants who were enrolled in the parent UCM vs ECC trial consented for this substudy. An echocardiogram was performed at 12 ± 6 hours of age by ultrasound technicians blinded to randomization. The primary outcome was left ventricular output (LVO). Prespecified secondary outcomes included measured superior vena cava (SVC) flow, right ventricular output (RVO), peak systolic strain, and peak systolic velocity by tissue Doppler examination of the RV lateral wall and the interventricular septum. RESULTS: Nonvigorous infants receiving UCM had increased hemodynamic echocardiographic parameters as measured by higher LVO (225 ± 64 vs 187 ± 52 mL/kg/min; P < .001), RVO (284 ± 88 vs 222 ± 96 mL/kg/min; P < .001), and SVC flow (100 ± 36 vs 86 ± 40 mL/kg/min; P < .001) compared with the ECC group. Peak systolic strain was lower (-17 ± 3 vs -22 ± 3%; P < .001), but there was no difference in peak tissue Doppler flow (0.06 m/s [IQR, 0.05-0.07 m/s] vs 0.06 m/s [IQR, 0.05-0.08 m/s]). CONCLUSIONS: UCM increased cardiac output (as measured by LVO) compared with ECC in nonvigorous newborns. Overall increases in measures of cerebral and pulmonary blood flow (as measured by SVC and RVO flow, respectively) may explain improved outcomes associated with UCM (less cardiorespiratory support at birth and fewer cases of moderate-to-severe hypoxic ischemic encephalopathy) among nonvigorous newborn infants.

RESUMEN

This study aimed to compare preterm (PT) and full-term (FT) infants' adaptive behavior and functional cortical response to tactile stimulus, as measured by Test of Sensory Functions in Infants and functional Near-Infrared Spectroscopy (fNIRS). Outcome measures were taken at 6 (PT = 26/FT = 21 infants) and 12 months (PT = 15/FT = 14 infants). At 6 months, poorer tactile reactivity was observed in PT, but not confirmed at 12 months. At 6 months, cortical response to tactile stimulus was found in the primary sensorimotor cortex and differences between groups did not reach significance. At 12 months, cortical response was found in the primary sensorimotor cortex and premotor area and in the somatosensory associative area, with significant less frequent response in premotor area in PT. The findings reinforce fNIRS as a tool to complement the knowledge of tactile adaptive behaviors in PT in early life.

RESUMEN

OBJECTIVE: To describe and compare the physiological signs presented by premature infants in traditional and humanized weighing. METHOD: A quasi-experimental crossover study, with a sample of 30 premature infants randomly assigned and allocated to the control group (traditional) and the intervention group (humanized), from March 2019 to March 2020, with the collection of general data, vital signs before and after the procedures. Statistical analyses included description of relative and absolute frequencies, measure of central tendency and dispersion. RESULTS: Premature infants showed less increase in heart rate (53.3%) and respiratory rate (43%) in the verification of humanized weighing than in the traditional way, with 83.3% of neonates and 80%, respectively. CONCLUSION: It was observed that the humanized form provided less physiological instability, especially in heart and respiratory rates, making it necessary to encourage discussions about the humanization of care and perform this practice routinely in health units.

Estudo longitudinal e avaliativo sobre o marco motor sentar em 11 lactentes, de ambos os sexos, com diagnóstico de prematuridade e idade cronológica de 6 a 8 meses. Os participantes foram divididos em dois grupos, o grupo intervenção que recebeu tratamento fisioterapêutico três vezes por semana durante seis semanas; e o grupo orientação, com encontros semanais durante o mesmo período com a fisioterapeuta que disponibilizou uma cartilha estruturada de exercícios a serem realizados pelos cuidadores durante a semana, sendo ambos os grupos com foco no sentar independente e avaliados com a escala AIMS. Foram encontradas diferenças significativas entre os resultados antes e após intervenção (t: -6.8571; p: 0,0012) assim como antes e após orientação (t: - 4.5995; p: 0.0029), sendo que ao analisar a porcentagem do ganho na dimensão sentar pela AIMS, o grupo intervenção teve maior ganho. Conclui-se que a intervenção fisioterapêutica apresentou melhores resultados para a aquisição do marco motor sentar. Apesar disso, a estimulação feita pelos pais após orientação profissional também apresentou valores positivos.

Prematurity can cause motor development deficits in infants, thus presenting the need for early intervention, in this sense the objective of this study was compare the motor development of preterm infants in the acquisition of the ability to sit independently after a motor intervention program and of orientation of parents for home stimuli. A longitudinal and evaluative study on the motor frame sit in 11 infants, of both sexes, with diagnosis of prematurity and chronological age of 6 to 8 months. Participants were divided into two groups, the intervention group that received physiotherapeutic treatment three times a week for six weeks; and the orientation group, with weekly meetings during the same period with the physiotherapist who provided a structured workbook of exercises to be performed by the caregivers during the week, both groups being focused on independent sitting and evaluated with the AIMS scale. There were significant differences between the results before and after intervention (t: -6.8571; p: 0.0012) as well as before and after orientation (t: -4.5995; p: 0.0029); when analyzing the percentage of gain in dimension by the AIMS, the intervention group had greater gain. It was concluded that the physiotherapeutic intervention presented better results for the acquisition of the motor frame sit. Despite this, the stimulation done by the parents after professional orientation also presented positive values.

RESUMEN

AIM: This systematic review aimed to differentiate and isolate the results of different music-based interventions used with preterm infants in the neonatal intensive care unit and explore their clinical benefits. METHODS: The last search was performed on 5 July 2021 on Web of Science, Scopus, EMBASE, PsycINFO, CINAHL, LILACS and CENTRAL. Only randomised clinical trials that explored the health benefits of music-based interventions were considered. RESULTS: A total of 39 studies were included. All music-based interventions were divided into music medicine and music therapy. The overall results suggested that music medicine interventions were associated with a significant improvement in pain relief; in turn, improvements in cardiac and respiratory function, weight gain, eating behaviour, and quiet alert and sleep states were more consistent in studies that followed a music therapy approach with the presence of a music therapist. CONCLUSION: This review supports the beneficial effects of music-based interventions on the health of preterm infants in a neonatal intensive care unit; however, it also offers suggestions for future studies in order to increase the number of interventions with music therapists, since the results of music therapy approaches were more consistent for physiological and behavioural outcomes.

RESUMEN

OBJECTIVE: To describe the relationship of oxidative stress and antioxidant biomarkers in cord blood of premature newborns and the prognosis of diseases in the neonatal period. SOURCES: This study consists of an integrative review. Searches were conducted in electronic databases Scopus, PubMed, Web of Science, and Medline/Lilacs through the Virtual Library on Health Issues, using the descriptors: "premature infants", "preterm infants", "preterm birth", "preterm", "oxidative stress", "antioxidants", "infant, premature, diseases" and "cord blood". Original articles published between 2016 and 2021 in Portuguese, English, or Spanish, which analyzed oxidative stress and/or antioxidant levels through cord blood of premature newborns and evaluated clinical outcomes, were included. SUMMARY OF THE FINDINGS: Of the 1,003 studies reviewed, after exclusion of duplicate articles, analysis of titles, abstracts, and full texts, 18 articles were included. 72.2% (n = 13) of analyzed studies reported a positive association between oxidative stress and the development of prematurity-related diseases; 27.7% (n = 5) showed no significant relation. Outcomes that showed a positive association were: intrauterine growth restriction, necrotizing enterocolitis, bronchopulmonary dysplasia, intraventricular hemorrhage, fetal inflammatory response syndrome, early-onset neonatal sepsis, retinopathy of prematurity, morbidity, and mortality. CONCLUSION: The analysis of oxidative stress and antioxidants in cord blood of premature newborns may be useful in the prognosis of some pathologies. The consequences of oxidative damage are known to be associated with increased morbidity in the short and long term. Further investigation is needed in this population in order to define normality parameters of biomarkers, clinical manifestations, diagnosis and treatment of these conditions.

RESUMEN

RESUMEN La hemorragia interventricular es una complicación frecuente en el recién nacido prematuro. Se presentó el caso con el objetivo de describir las complicaciones en la hemorragia intraventricular en el recién nacido. Se trató de una recién nacida, producto de un embarazo de 30 semanas de gestación, con peso al nacer de 1 600 g. Desarrolló una hemorragia intraventricular e hidrocefalia que requirió diferentes intervenciones neuroquirúrgicas y desarrolló complicaciones sépticas graves. La ventriculitis y los abscesos cerebrales fueron las complicaciones más peligrosas. Se realizaron lavados ventriculares. Se utilizó antibióticos intraventriculares y también antibioticoterapia sistémica, cambios frecuentes de catéter de derivación al exterior y permanencia de una derivación ventricular externa por 102 días. Después de seis meses de evolución, de más de veinte intervenciones quirúrgicas, y de haber sufrido severas complicaciones sépticas, se logró realizar la derivación ventrículo-peritoneal definitiva, lográndose su egreso. Al año de vida, la paciente mantiene un desarrollo psicomotor adecuado (AU).

ABSTRACT The interventricular hemorrhage is a frequent complication in the premature newborn baby. The case was presente with the aim of describing the complications of intraventricular hemorrhage in the newborn baby. It dealed with a female newborn baby, product of a 30 weeks pregnancy, with weight at birth of 1 600 g. She developed intraventricular hemorrhage and hydrocephalus that required different neurosurgical interventions and developed serious septic complications. Ventriculitis and brain abscesses were the most dangerous complications. Ventricular lavages were performed. Intraventricular antibiotics were used as well as systemic antibiotic therapy, frequent changes of bypass catheter to the exterior and permanence of an external ventricular bypass for 102 days. And permanence of an external ventricular shunt for 102 days. After six months of evolution, more than twenty surgical interventions, and having suffered severe septic complications, it was possible to perform the definitive ventricular-peritoneal bypass, achieving her discharge. At a year of life, the patient maintains adequate psychomotor development (AU).

RESUMEN

OBJECTIVES: To assess kinematic parameters and proximal and distal reaching adjustments of infants at biological or environmental risk and compare with reaching performance of six-month-old full-term infants without known risk factors. METHODS: This blinded cross-sectional study included 62 infants at six months of age divided into three independent groups: Group with no known risk factor (NRF), 28 full-terms with no risk factors; Low SES group (LSES):19 full-terms classified as low socioeconomic status and no biological risk; Very preterm group (VPT), 15 very preterm infants at six months corrected age and no environmental risk. Infants were placed in a reclined baby chair at 45°, and a malleable and unfamiliar object was presented to the infant at 5-second intervals to elicit reaching movements. RESULTS: Infants from LSES presented reaching duration (p = 0.032, Cohen's f = 0.349) and movement unit (p = 0.033, Cohen's f = 0.351) significantly higher than VPT group. Horizontal hand orientation was moderately associated with infants at environmental risk (p = 0.031; Cramer's V = 0.30). CONCLUSION: Infants of low socioeconomic status perform less functional reaching movements than very preterm infants at six months corrected age. Socioeconomic status may impact more on reaching skills than biological risk. Given the importance of reaching for infant development, low-cost public health strategies are needed to identify possible delays.

RESUMEN

Premature newborns, especially the extreme ones, need to be cared for in the different units in the neonatal services. In addition to ensuring the survival of these newborns, these services have gra dually incorporated interventions to promote their development. This review provides an updated synthesis of developmental-focused neonatal care. First, it describes the neurobiological theoretical foundations that explain how the so-called "neonatal stress" can affect the development of a prema ture child. Later, it reviews the Synactive Theory, which is one of the theoretical models that contri bute to understanding the characteristics of the care focused on development. Regarding this care, the evidence and challenges for implementing are described and addressed from a critical perspective, pointing out the strengths and weaknesses. This article highlights the importance of improving the quality of care that preterm newborns received in NICUs, promoting resilience and/or the best pos sible developmental potential in these children, in addition to strengthening the role of parents in neonatal care.

RESUMEN

To assess stress experienced during Neonatal Intensive Care Unit (NICU) stay, we analyzed fingernail Cortisol (CORT) and Dehydroepiandrosterone (DHEA) levels and ratios in mothers and preterm infants (PI); compared hormones levels/ratio (CORT and DHEA) in kangaroo care (KC) versus standard care (SC) groups and examined relationships between PI hormone levels total days spent in the NICU. Mothers and their infants were recruited in the NICU, included levels I-IV and kangaroo care unit, within one week of infant birth in hospitals in Brazil. At 3 months after birth, mothers provided 3-month growth clippings from all ten digits of their own and their infants' fingernails. CORT and DHEA were measured using enzyme immunoassays (mothers) and high-performance-liquid-chromatography-with-mass-spectrometry (infants). Sample: n = 59 mothers (KC = 30/SC = 29) and 63 infants (KC = 32/SC = 31). Data were analyzed using non-parametric/parametric comparative statistics. NICU stay ranged from 3-103 days. For mothers in Kangaroo and Standard Care the CORT, DHEA levels and DHEA:CORT ratio (DC) ratio did not differ. Infants in KC had higher DHEA (p = 0.003) and a higher DC ratio (p = 0.011) than SC infants. Even though KC infants stayed in the NICU for a greater number of days than infants in SC, they had higher mean level of DHEA, and DC ratio, suggesting that KC played a role in promoting their stress regulatory capacities and may mitigate toxic effects of chronic hypercortisolemia. However, for mothers, KC did not reduce chronic stress compared to that in women in the SC condition. Further research warranted.
