Trends in survival, perinatal morbidities and two-year neurodevelopmental outcomes in extremely low-birthweight infants over four decades

The Landscape of Resource Utilization After Resuscitation of 22-, 23-, and 24-Weeks' Gestation Infants

OBJECTIVE

To compare estimated healthcare resources needed to care for 22 through 24 weeks' gestation infants.

STUDY DESIGN

This multicenter, retrospective cohort study included 1505 live in-born and out-born infants 22 through 24 weeks' gestational age at delivery from 6 pediatric tertiary care hospitals from 2011 through 2020. Median neonatal intensive care unit (NICU) length of stay (LOS) for each gestational age was used as a proxy for hospital resource utilization, and the number of comorbidities and medical technology use for each infant were used as estimates of future medical care needs. Data were analyzed using Kruskal-Wallis with Nemenyi's posthoc test and Fisher's exact test.

RESULTS

Of the identified newborns, 22-week infants had shorter median LOS than their 23- and 24-week counterparts due to low survival rates. There was no significant difference in LOS for surviving 22-week infants compared with surviving 23-week infants. Surviving 22-week infants had similar proportions of comorbidities and medical technology use as 23-week infants.

CONCLUSIONS

Compared with 23- and 24-week infants, 22-week infants did not use a disproportionate amount of hospital resources. Twenty-two-week infants should not be excluded from resuscitation based on concern for increased hospital care and medical technology requirements. As overall resuscitation efforts and survival rates increase for 22-week infants, future research will be needed to assess the evolution of these results.

Reflections about being born extremely preterm in children and adolescents: A qualitative descriptive study

BACKGROUND

The survival of the smallest and most immature preterm infants, born at 23-24 weeks of gestation, has improved significantly. While there is a substantial amount of research on the neurocognitive and social outcomes of extremely premature birth, little is known about the survivors' subjective experience of being born preterm and its effect on later life.

AIMS

The purpose was to study the subjective experiences of school-aged children born at 23-24 weeks of gestation, in order to understand their perspectives on how being born extremely early had affected their life.

STUDY DESIGN

Qualitative descriptive study.

METHODS

18 school-aged children (12 girls and 6 boys, 7-15 years of age), born at 23 or 24 weeks of gestation, were interviewed. The semi-structured interview guide covered six topics about quality of life: somatic health, functioning, learning and memory, emotional health, social relations, experience of prematurity and its effect.

RESULTS

Most children reported memories, which were told to them by parents, about their premature birth and early life. Using qualitative thematic analysis, the narratives of the children were classified into three groups: 1) the go-with-the-flow children, who identified little or no effect of prematurity, 2) the ponderers, who reflected on some effects such as minor physical challenges, and 3) the hesitants, who either did not connect their challenges with prematurity, or did not produce much reflection overall.

CONCLUSIONS

Children had been told about their early life by the parents and repeated these memories indicating that prematurity had become a significant part of the family story. Differences were found how the children reflected on the impact of prematurity in their personal life. It is essential to include preterm survivors' own perspectives already during childhood and adolescence into the research of extreme prematurity.

Optimizing trajectories of social adaptive competencies after extreme prematurity during the first 1000 days

Over 75% of surviving extremely preterm infants do not have major neurodevelopmental disabilities; however, more than half face difficulties with communication, coordination, attention, learning, social, and executive function abilities. These "minor" challenges can have a negative impact on educational and social outcomes, resulting in physical, behavioral, and social health problems in adulthood. We will review assessment tools for social-emotional and adaptive functional skills in early childhood as these determine family and early childhood supports. We highlight bronchopulmonary dysplasia as an example of the critical intersections of parental wellbeing, medical and developmental adaptive trajectories in infancy and early childhood, and partnerships between child neurologists and community medical and developmental professionals. We examine studies of engaging parents to promote developmental trajectories, with a focus on supporting parent-child interactions that underlie communication, social-adaptive behaviors, and learning in the first 1000 days of life. Recommendations for neurodevelopmental surveillance and screening of extremely preterm infants can also be applied to infants with other risk factors for altered neurodevelopment.

Trajectories of antepartum depressive symptoms and birthweight: a multicenter and prospective cohort study

BACKGROUND

Antepartum depression is a prevalent unhealthy mental health problem worldwide, particularly in low-income countries. It is a major contributor to adverse birth outcomes. Previous studies linking antepartum depression to birthweight have yielded conflicting results, which may be the reason that the depressive symptoms were only measured once during pregnancy. This study aimed to explore the associations between trajectories of antepartum depressive symptoms and birthweight.

METHODS

Depressive symptoms were assessed prospectively at each trimester in 3699 pregnant women from 24 hospitals across 15 provinces in China, using the Edinburgh Postpartum Depression Scale (EPDS). Higher scores of EPDS indicated higher levels of depressive symptoms. Associations between trajectories of depressive symptoms and birthweight were examined using group-based trajectory modeling (GBTM), propensity score-based inverse probability of treatment weighting (IPTW), and logistic regression.

RESULTS

GBTM identified five trajectories. Compared with the low-stable trajectory of depressive symptoms, only high-stable (OR = 1.35, 95% CI: 1.15-2.52) and moderate-rising (OR = 1.18, 95% CI: 1.12-1.85) had an increased risk of low birthweight (LBW) in the adjusted longitudinal analysis of IPTW. There was no significant increase in the risk of LBW in moderate-stable and high-falling trajectories. However, trajectories of depressive symptoms were not associated with the risk of macrosomia.

CONCLUSION

Antepartum depressive symptoms were not constant. Trajectories of depressive symptoms were associated with the risk of LBW. It is important to optimize and implement screening, tracking, and intervention protocols for antepartum depression, especially for high-risk pregnant women, to prevent LBW.
