Early intervention program for very low birth weight preterm infants and their parents: a study protocol.

ABSTRACT: BACKGROUND:Preterm infants are high risk for delayed neurodevelopment. The main goal is to develop a program of early intervention for very preterm infants that allows families to apply it continuously at home, and quantify the results of early parental stimulation on improvement of cognition and motor skills. METHODS:Randomized clinical Trial including inborn preterm infants with gestational age less than 32 weeks or birth weight less than 1500 g at 48 h after birth. Eligible for begin the intervention up to 7 days after birth. Study Protocol approved by the Brazilian national Committee of ethics in Research and by the institutional ethics committee. Intervention group (IG): skin-to skin care by mother (kangaroo care) plus tactile-kinesthetic stimulation by mothers from randomization until hospital discharge when they receive a program of early intervention with 10 parents' orientation and a total of 10 home visits independently of the standard evaluation and care that will be performed. Systematic early intervention program will be according to developmental milestones, anticipating in a month evolutionary step acquisition of motor and / or cognitive expected for corrected age. Active comparator with a Conventional Group (CG): standard care according to the routine care of the NICU and their needs in the follow up program. Neurodevelopment outcome with blinded evaluations in both groups between 12 and 18 months by Bayley Scales of Infant and Toddler Development third edition and Alberta Motor Infant scale will be performed. All evaluations will be conducted in the presence of parents or caregivers in a safe room for the child move around during the evaluation. DISCUSSION:If we can show that a continuous and global early intervention at home performed by low income families is better than the standard care for very preterm infants, this kind of program may be applied elsewhere in the world. We received grants by Bill and Melinda Gates Foundation, DECIT, Cnpq and Health Ministry. Grand Challenges Brazil: All Children Thriving. TRIAL REGISTRATION:The study was restrospectively registered in ClinicalTrials.gov . in July 15 2016 ( NCT02835612 ).

Project description:The aim of the present study was to examine the changes in bacteria in hospitalized preterm infants during the first month of life.Rectal swabs were collected daily from 12 preterm infants. DNA was extracted from swabs from day of birth and weekly thereafter. Bacterial taxa were identified with next generation sequencing using universal bacterial primers targeted at the 16S ribosomal DNA on a 454 Roche titanium platform. Sequences were clustered into operational taxonomic units, and taxonomy was assigned against the Greengenes databank using Quantitative Insights Into Microbial Ecology version 1.4. Quantitative polymerase chain reaction was used to determine the abundance of Bifidobacterium spp. Functional assessment of the microbiome was performed with Phylogenetic Investigation of Communities by Reconstruction of Unobserved States (PICRUSt).Average birth weight and gestational age were 1055 g and 28 weeks, respectively. There were 6 to 35 different bacterial families identified in the day-of-birth samples, unrelated to the mode of delivery. Richness decreased through hospitalization (week 1, 16.9?±?7.7 vs weeks 3-5, 10.7?±?3.4, P?<?0.001). The Shannon diversity index demonstrated the lowest diversity at birth, an increase at week 2, followed by a rapid decline at weeks 3 to 5, suggesting the development of a more uniform microbiota composition after 2 weeks of stay at a neonatal intensive care unit. Enterobacteriaceae, Staphylococcaceae, and Enterococcaceae constituted the majority of the bacterial families. Bifidobacterium spp were infrequently detected at extremely low levels. PICRUSt analysis revealed the enhancement of peroxisome, PPAR, and adipocytokine signaling; plant-pathogen interaction; and aminobenzoate degradation pathways in week 1 samples.Our results suggest that although preterm infants have individualized microbiota that are detectable at birth, the differences decrease during the neonatal intensive care unit hospitalization with increasing prominence of pathogenic microbiota.
