Hospitalising preterm infants in single family rooms versus open bay units: a systematic review and meta-analysis.

BACKGROUND: The effect of the hospital environment on health and specifically neurodevelopment in preterm infants remains under debate. We assessed outcomes of preterm infants hospitalised in single family rooms compared with common open bay units. METHODS: For this systematic review and meta-analysis, we searched MEDLINE, Embase, PsycInfo, CENTRAL (the Cochrane Central Register of Controlled Trials), Web of Science, and ClinicalTrials.gov from inception to Aug 13, 2018, using controlled terms (ie, MeSH terms) and text words related to prematurity and neonatal intensive care unit design. We included randomised and non-randomised studies investigating clinical outcomes of preterm infants. We assessed methodological quality using the Cochrane Collaboration's Risk of Bias Tool for randomised controlled trials and the Cochrane Risk of Bias Tool for Non-randomised Studies of Interventions. We calculated summary estimates for meta-analysis using random effects models. The primary outcome was age appropriate long-term neurodevelopment. Secondary outcomes were length of hospital stay, sepsis, breastfeeding, growth, bronchopulmonary dysplasia, intraventricular haemorrhage, retinopathy of prematurity, and mortality. This systematic review is registered with PROSPERO, number CRD42016050643. FINDINGS: We identified 487 records. 13 study populations (n=4793) were included. No difference in cognitive neurodevelopment was found on the Bayley Scales of Infant and Toddler Development-III at 18-24 months of corrected age (680 infants analysed; mean difference 1·04 [95% CI -3·45 to 5·52], p=0·65; I2=42%). The incidence of sepsis was lower (4165 infants analysed; 108 035 days in hospital [hospitalisation days]; risk ratio 0·63 [95% CI 0·50 to 0·78], p<0·0001; I2=0%) and exclusive breastfeeding at discharge was higher (484 infants analysed; 1·31 [1·07 to 1·61], p=0·01; I2=0%) in single family rooms than in open bay units. We found no differences in length of hospital stay, growth, bronchopulmonary dysplasia, intraventricular haemorrhage, retinopathy of prematurity, and mortality. INTERPRETATION: Single family rooms should be considered to hospitalise preterm infants because incidence of sepsis is reduced and exclusive breastfeeding is higher. No difference in long-term neurodevelopment was detected. FUNDING: None.

When the right (Drug) should be left: Prenatal drug exposure and heterotaxy syndrome.

BACKGROUND: Recent studies reported an association between prenatal propylthiouracil exposure and birth defects, including abnormal arrangement across the left-right body axis, suggesting an association with heterotaxy syndrome. METHODS: This case-control and case-finding study used data from 1981 to 2013 from the EUROCAT birth defect registry in the Northern Netherlands. First, we explored prenatal exposures in heterotaxy syndrome (cases) and Down syndrome (controls). Second, we describe the specific birth defects in offspring of mothers using propylthiouracil (PTU) prenatally. RESULTS: A total of 66 cases with heterotaxy syndrome (incidence 12.1 per 100,000 pregnancies) and 783 controls with Down syndrome (143.3 per 100,000 pregnancies) were studied. No differences in intoxication use during pregnancy were found between cases and controls, including smoking (28.0% vs. 22.7%; p = 0.40), alcohol (14.0% vs. 26.9%; p = 0.052), and recreational drugs (0 vs. 0.3%; p = 1.00). We found an association between heterotaxy syndrome and prenatal drug exposure to follitropin-alfa (5.6% vs. 1.1%; p = 0.04), and drugs used in nicotine dependence (3.7% vs. 0.2%; p = 0.02). Five mothers used PTU during pregnancy and gave birth to a child with trisomy 18, renal abnormalities, or hypospadias and cardiac defects. CONCLUSION: This study identified follitropin-alfa and drugs used in nicotine dependence as possible teratogens of heterotaxy syndrome. Our data suggest the possibility that there is an increased risk of birth defects (including renal, urological, and cardiac abnormalities) in children born among mothers taking PTU prenatally, but not for heterotaxy syndrome.
