Infants born prematurely (before completion of 37 weeks of gestation) are at increased risk of morbidity and mortality due to vaccine preventable diseases, mostly because of their immunological immaturity and failure of transfer of maternal protective antibodies. Despite their great need of being vaccinated, concerns on vaccine safety and efficacy, constitute the main reasons for which vaccinations are often delayed in this group. In this review we summarize the latest evidence on vaccine safety, efficacy and immunogenicity in preterm infants which is similar to full-term infants. Therefore there is no reason for delaying vaccination in this population.

Background: Late preterm babies, born between 34 completed weeks of gestation through 36 weeks 6/7 gestation, tend to be physiologically less mature than term infants, subjecting them to an increased risk of developing various morbidities. Limited information is available regarding the current scenario in India. Therefore, the objective of this study was to understand and compare the early morbidities in late preterm newborns with those in full term babies in a tertiary hospital in India.Methods: The current prospective, observational study consisted of total 150 babies divided into two groups equally; late preterm neonates born between 34 and 36 weeks of gestation and full-term neonates. Weight (at birth, at 72 hours), heart rate, temperature and respiratory parameters were noted of all babies. The newborns were examined for respiratory morbidities, ability to breastfeed, hypoglycemia, hypothermia, neonatal jaundice and signs of sepsis. The need for resuscitation, admission to neonatal intensive care unit (NICU) and parenteral nutrition was also assessed. Data was expressed as mean±SD and was analyzed using the Student ‘t’ and Mann Whitney U tests.Results: The mean length and weight at birth in late preterm babies was significantly lesser than term newborns. Late preterm babies were found to have significantly higher incidence of complications like hyperbilirubinemia (62.7% vs 13.3%), respiratory morbidities (16% vs 4%), poor feeding, hypothermia, hypoglycemia, and sepsis compared to term newborns (p<0.01).Conclusions: Late preterm infants are at a higher risk than term infants for a number of neonatal complications. Initiatives imparting special care to late preterm infants are required in order to lower the morbidities endured by this population.

Abstract Background and Purposes. Although early kicking differences have been reported for preterm infants without overt cranial sonographic abnormalities, their functional importance remains unclear because no outcomes have been measured. Therefore, the first purpose of this prospective study was to examine the age of walking attainment in preterm infants who had very low birth weight (VLBW) but no overt neurosonographic abnormalities and full-term infants without known impairments or pathology. The second purpose was to examine the relationship between spontaneous kicking and age of walking attainment in these infants. Subjects and Methods. Twenty-two preterm infants and 22 full-term infants were examined for kicking movements at 2 and 4 months corrected age and were followed up for age of walking attainment until 18 months corrected age. Results. Survival analysis showed that infants with VLBW attained walking ability at older ages than full-term infants after correction for prematurity. Cox proportional-hazards regression analyses for all infants revealed that a high hip-knee correlation at 2 months corrected age, a high kick frequency at 4 months corrected age, and a short intra-kick pause together with a low variability in interlimb coordination at 2 and 4 months corrected age were all associated with a decreased rate of walking attainment. Discussion and Conclusion. The results indicated that preterm infants who had VLBW but no overt neurosonographic abnormalities had an increased risk of delayed walking attainment compared with full-term infants. Alterations of spontaneous kicking may predict a decreased rate of walking attainment in both preterm and full-term infants.

BACKGROUND Late preterm infants are less mature physiologically and have poor compensatory responses when compared to term infants. Recent studies have implied increased morbidities in late preterm infants and higher rate of hospital admission during neonatal period. Multiple maternal risk factors lead to the increasing incidence of late preterm births. We wanted to study the morbidity and mortality profile of late preterm infants compared to term infants. METHODS The study was conducted in the special newborn care unit (SCNU) of Silchar Medical College and Hospital. The study population comprised of 175 late preterm and 175 term babies admitted in SCNU. It was a cross sectional study. RESULTS In this study 175 late preterm neonates were compared with 175 term neonates. Late preterm babies were at increased risk of hypoglycemia (P value = 0.0130), neonatal jaundice (P = 0.021), culture positive sepsis (P = 0.001), respiratory distress (P = 0.000), hypocalcaemia (P = 0.030), difficulty in feeding (P = 0.000) and birth asphyxia (P = 0.013), longer hospital stay and mortality (P = 0.009) when compared to term babies. In babies of mothers with oligohydramnios and pregnancy induced hypertension, preterm babies had significant morbidity compared to term babies. CONCLUSIONS Late preterm babies have an increased risk of morbidity and mortality when compared to term neonates and need special care. Premature rupture of membranes, antepartum hemorrhage and pre-eclampsia are the main maternal complications leading to premature delivery of the baby.

Background: Preterm birth is defined as birth before 37 completed weeks of pregnancy. It is the most important predictor of adverse health and development infant outcomes that extend into the early childhood and beyond. It is also the leading cause of childhood mortality under 5 years of age worldwide and responsible for approximately one million neonatal deaths. It is also a significant contributor to childhood morbidities, with many survivors are facing an increased risk of lifelong disability and poor quality of life. Purpose: In this article, we aimed to describe features of preterm infants, what makes them different from term infants, and what to consider in nutritional management of preterm infants through a traditional narrative literature review. Discussion: Preterm infants are predisposed to more health complications than term infants with higher morbidity and mortality. This morbidity and mortality can be reduced through timely interventions for the mother and the preterm infant. Maternal interventions, such as health education and administration of micronutrient supplementation, are given before or during pregnancy and at delivery, whereas appropriate care for the preterm infants should be initiated immediately after birth, which include early breastfeeding and optimalization of weight gain. Conclusion: Essential care of the preterm infants and early aggressive nutrition should be provided to support rapid growth that is associated with improved neurodevelopmental outcomes. The goal is not only about survival but making sure that these preterm infants grow and develop without any residual morbidity.

Father Attachment

This study examines the infant–father attachment in infants born preterm (<  1500 g at birth and/or <  37 weeks gestation) in comparison to full-term infants. The infant–father attachment was assessed using the Strange Situation Procedure at a (corrected) age of 15 months. We found at least half of preterm and full-term infants (50.0% and 56.5 % respectively) securely attached to their fathers, and no significant overall difference was observed concerning the distribution of attachment quality comparing the two groups. In light of the fact that preterm infants tend to have numerous neurodevelopmental problems, it is encouraging that significant differences were not found in the distribution of the attachment quality among the groups. Therefore, from the perspective of attachment research, it would be highly beneficial to include fathers in the care of their preterm infants.

Obstructive Sleep Apneas

Objective. To investigate the effect of body rocking on infant respiratory behavior during sleep. Methods. Eighteen infants with documented obstructive sleep apneas were studied. There were eight premature infants with persistent bradycardias and 10 infants born full-term, admitted after an idiopathic apparent life-threatening event. No cause for the obstructive apneas was found. The infants were recorded with polygraphic techniques during two successive nights. They were randomly assigned to a rocking or a nonrocking mattress. The conditions were reversed the following night, in a crossover design. Results. In both groups of infants, no significant difference was seen between the two consecutive nights for most of the variables studied: total sleep time, the proportion of non-rapid-eye-movement and rapid-eye-movement sleep, the number of arousals, the number and maximal duration of central apneas, the frequency of periodic breathing, the level of oxygen saturation, and heart rate. During the nonrocking nights, all infants had repeated obstructive breathing events. In seven of the eight preterm infants and in nine of the 10 full-term subjects, body rocking was associated with a significant decrease in the frequency of obstructive events. During rocking, in the preterm infants the obstructions fell from a median of 2.5 to 1.8 episodes per hour (P = .034). In the full-term infants, rocking reduced the obstructive events from a median of 1.5 obstructions per hour to 0.7 (P = .005). No difference was seen for the duration of the obstructive episodes. Conclusion. In preterm and full-term infants prone to obstructive sleep apneas, gentle side-to-side body rocking is associated with a significant decrease in the frequency of upper-airway obstructions.

Sensory Prediction

Recent findings have shown that full-term infants engage in top–down sensory prediction, and these predictions are impaired as a result of premature birth. Here, we use an associative learning model to uncover the neuroanatomical origins and computational nature of this top–down signal. Infants were exposed to a probabilistic audiovisual association. We find that both groups (full term, preterm) have a comparable stimulus-related response in sensory and frontal lobes and track prediction error in their frontal lobes. However, preterm infants differ from their full-term peers in weaker tracking of prediction error in sensory regions. We infer that top–down signals from the frontal lobe to the sensory regions carry information about prediction error. Using computational learning models and comparing neuroimaging results from full-term and preterm infants, we have uncovered the computational content of top–down signals in young infants when they are engaged in a probabilistic associative learning.

Abstract Thrombocytopenia is a common problem among sick neonates admitted to the neonatal intensive care unit. Frequently, platelet transfusions are given to thrombocytopenic infants in an attempt to decrease the incidence or severity of hemorrhage, which is often intracranial. Whereas there is very limited evidence to guide platelet transfusion practices in this population, preterm infants in the first week of life (the highest risk period for bleeding) are nearly universally transfused at higher platelet counts than older infants or children. To a large extent, this practice has been influenced by the observation that neonatal platelets are hyporeactive in response to multiple agonists in vitro, although full-term infants exhibit normal to increased primary hemostasis. This apparently paradoxical finding is due to factors in the neonatal blood that enhance the platelet-vessel wall interaction and counteract the platelet hyporeactivity. Relatively few studies have evaluated the platelet function and primary hemostasis of preterm infants, the subset of neonates at highest risk of bleeding and those most frequently transfused. Current understanding of platelet production and function in preterm and full-term neonates, how these factors affect their response to thrombocytopenia and their primary hemostasis, and the implications of these developmental differences to transfusion medicine are reviewed herein.

Age Studies

The influence of maturation on extrathoracic airway (ETA) stability during quiet sleep was determined in 13 normal preterm infants of 1.41 +/- 0.14 (SD) kg birth weight and 32 +/- 2 wk estimated gestational age. Studies began in the first week of life and were performed three times at weekly intervals. A drop in intraluminal pressure within the ETA was produced by external inspiratory flow-resistive loading (60 cmH2O.l-1 x s at 1 l/min); an increase in intrinsic resistance, indicating airway narrowing, was sought as a measure of ETA instability. Baseline total pulmonary resistance was not significantly different between weeks 1, 2, and 3 (88 +/- 35, 65 +/- 24, and 61 +/- 17 cmH2O.l-1 x s, respectively) but increased markedly above baseline with loading to 144 +/- 45 cmH2O.l-1.s during week 1 (P < 0.001), 89 +/- 28 cmH2O.l-1 x s at week 2 (P < 0.01), and 74 +/- 25 cmH2O.l-1 x s at week 3 (n = 10). The increment with loading was significantly greater during week 1 than during weeks 2 or 3 (P < 0.02). Similar studies were also done in seven full-term infants in the first week of life to evaluate the influence of gestational maturity on ETA stability. Despite a relatively greater drop in intraluminal pressure within the ETA of term vs. preterm infants with loading (P < 0.001), total pulmonary resistance failed to increase (68 +/- 21 to 71 +/- 32 cmH2O.l-1.s). These data reveal that ETA instability is present in preterm infants at birth and decreases with increasing postnatal age. Full-term neonates, by comparison, display markedly greater ETA stability in the immediate neonatal period.
