Very preterm birth not associated with mood & anxiety disorders

Do very-preterm or very-low-weight babies develop anxiety and mood disorders later in life? Researchers have concluded a study to answer this question | ScienceDaily

The team studied nearly 400 individuals from birth to adulthood. Half of the participants had been born before 32 weeks gestation or at a very low birth weight (less than 3.3 pounds), and the other half had been born at term and normal birth weight. They assessed each participant when they were 6, 8 and 26 years old using detailed clinical interviews of psychiatric disorders.

“Previous research has reported increased risks for anxiety and mood disorders, but these studies were based on small samples and did not include repeated assessments for over 20 years,”

Their results? At age 6, children were not at an increased risk of any anxiety or mood disorders, but by age 8 — after they had entered school — more children had an anxiety disorder. By 26, there was a tendency to have more mood disorders like depression, but the findings were not meaningfully different between the two groups.

This study is the first investigation of anxiety and mood disorders in childhood and adulthood using clinical diagnoses in a large whole-population study of very preterm and very-low-birth-weight individuals as compared to individuals born at term.

The team also found that having a romantic partner who is supportive is an important factor for good mental health because it helps protect one from developing anxiety or depression. However, the study found fewer very-preterm-born adults had a romantic partner and were more withdrawn socially.

Retrospective cohort study of all deaths among infants born between 22 and 27 completed weeks of gestation

The aim of this research is to assess causes and circumstances of deaths in extremely low gestational age neonates (ELGANs) born in Switzerland over a 3-year period | BMJ Open

Design: Population-based, retrospective cohort study.

Setting: All nine level III perinatal centres (neonatal intensive care units (NICUs) and affiliated obstetrical services) in Switzerland.

Patients: ELGANs with a gestational age (GA) <28 weeks who died between 1 July 2012 and 30 June 2015.

Results: A total of 594 deaths were recorded with 280 (47%) stillbirths and 314 (53%) deaths after live birth. Of the latter, 185 (59%) occurred in the delivery room and 129 (41%) following admission to an NICU. Most liveborn infants dying in the delivery room had a GA ≤24 weeks and died following primary non-intervention. In contrast, NICU deaths occurred following unrestricted life support regardless of GA. End-of-life decision-making and redirection of care were based on medical futility and anticipated poor quality of life in 69% and 28% of patients, respectively. Most infants were extubated before death (87%).

Conclusions: In Switzerland, most deaths among infants born at less than 24 weeks of gestation occurred in the delivery room. In contrast, most deaths of ELGANs with a GA ≥24 weeks were observed following unrestricted provisional intensive care, end-of-life decision-making and redirection of care in the NICU regardless of the degree of immaturity.

Highlights:

  • Despite its known efficacy, kangaroo care is not practiced in all US hospitals.
  • Without adequate weight gain, preterm infants can experience longer hospital stays.
  • Improved weight gain can reduce hospital readmissions and developmental issues.
  • Kangaroo care is a low-cost modality that can increase preterm infant weight gain.

The Speed of Increasing milk Feeds: RCT Protocol

Abbott, J. et al. BMC Pediatrics. Published: 28 January 2017

Background: In the UK, 1–2% of infants are born very preterm (<32 weeks of gestation) or have very low birth weight (<1500 g). Very preterm infants are initially unable to be fed nutritional volumes of milk and therefore require intravenous nutrition. Milk feeding strategies influence several long and short term health outcomes including growth, survival, infection (associated with intravenous nutrition) and necrotising enterocolitis (NEC); with both infection and NEC being key predictive factors of long term disability.

Currently there is no consistent strategy for feeding preterm infants across the UK. The SIFT trial will test two speeds of increasing milk feeds with the primary aim of determining effects on survival without moderate or severe neurodevelopmental disability at 24 months of age, corrected for prematurity. The trial will also examine many secondary outcomes including infection, NEC, time taken to reach full feeds and growth.

Newborn Individualized Developmental Care and Assessment Program Reduces Length of Stay

Moody, C. et al. Journal of Pediatric Nursing. Published online: 3 December 2016

871-2

Infants born at ≤32 weeks gestation are at risk of developmental delays. Review of the literature indicates NIDCAP improves parental satisfaction, minimizes developmental delays, and decreases length of stay, thus reducing cost of hospitalization.

Highlights:

  • NIDCAP is a proven framework for providing developmentally supportive care in the NICU, and can mitigate risks of prematurity
  • Earlier initiation of NIDCAP led to discharge at a younger post-menstrual age
  • Quality improvement investigations are effective in addressing critical healthcare needs

Impact of a Transition Home Program on Rehospitalization Rates of Preterm Infants

Vohr, B. et al. The Journal of Pediatrics. Published online: 3 November 2016

home-1353389_960_720

Objectives: To evaluate the effects of a transition home program on 90-day rehospitalization rates of preterm (PT) infants born at <37 weeks gestational age implemented over 3 years for infants with Medicaid and private insurance, and to identify the impact of social/environmental and medical risk factors on rehospitalization.

Study design: In this prospective cohort study of 954 early, moderate, and late PT infants, all families received comprehensive transition home services provided by social workers and family resource specialists (trained peers) working with the medical team. Rehospitalization data were obtained from a statewide database and parent reports. Group comparisons were made by insurance type. Regression models were run to identify factors associated with rehospitalization and duration of rehospitalization.

Results: In bivariable analyses, Medicaid was associated with more infants hospitalized, more than 1 hospitalization, and more days of hospitalization. Early PT infants had more rehospitalizations by 90 days than moderate (P = .05) or late PT infants (P = .01). In regression modeling, year 3 of the transition home program vs year 1 was associated with a lower risk for rehospitalization by 90 days (OR, 0.57; 95% CI, 0.36-0.93; P = .03). Medicaid (P = .04), non–English-speaking (P = .02), multiple pregnancies (P = .05), and bronchopulmonary dysplasia (P = .001) were associated with increased risk. Both bronchopulmonary dysplasia and Medicaid were associated with increased days of rehospitalization in adjusted analyses. The major cause of rehospitalization was respiratory illness (61%).

Conclusions: Transition home prevention strategies must be directed at both social/environmental and medical risk factors to decrease the risk of rehospitalization.

Effect of Delayed Cord Clamping on Systemic Blood Flow: A Randomized Controlled Trial

Popat, H et al. (2016) The Journal of Pediatrics178. pp. 81–86.e2

Objective: To determine whether delayed cord clamping improves systemic blood flow compared with immediate cord clamping in very preterm infants in the first 24 hours.

Study design: Women delivering at <30 weeks’ gestation at 5 tertiary centers were randomized to receive immediate cord clamping (<10 seconds) or delayed cord clamping (≥60 seconds). Echocardiography and cardiorespiratory data were collected at 3, 9, and 24 hours after birth. The primary outcome was mean lowest superior vena cava (SVC) flow.

Results: Of 266 infants enrolled, 133 were randomized to immediate cord clamping and 133 to delayed cord clamping. The 2 groups were similar at baseline, including mean gestation (immediate cord clamping 28 weeks vs delayed cord clamping 28 weeks) and birth weight (immediate cord clamping 1003 g vs delayed cord clamping 1044 g). There was no significant difference between groups in the primary outcome of mean lowest SVC flow (immediate cord clamping 71.4 mL/kg/min [SD 28.1] vs delayed cord clamping 70.2 mL/kg/min [SD 26.9]; P = .7). For secondary outcomes, hemoglobin increased by 0.9 g/dL at 6 hours in the group with delayed cord clamping (95% CI 3.9, 14.4; P = .0005, adjusted for baseline). The group with delayed cord clamping had lower right ventricular output (−21.9 mL/kg/min, 95% CI −39.0, −4.7; P = .01). Rates of treated hypotension, ductus arteriosus size and shunt direction, and treatment of the ductus arteriosus were similar.

Conclusions: Delayed cord clamping had no effect on systemic blood flow measured as mean lowest SVC flow in the first 24 hours in infants <30 weeks’ gestation.
