Treatment for Post-hemorrhagic Ventricular Dilatation:A Multiple-Treatment Meta-Analysis

Objective: To perform a systematic review and multiple-treatment meta-analysis for the treatment of premature infants with post-hemorrhagic ventricular dilatation (PHVD), to prevent death or long-term neuro-disability. Design/Method: Asystematicreviewwasperformedusing PubMed, EMBASE, andthe Cochrane Library. A free-word search was performed to identify likely relevant literature intervention trials of PHVD in preterm infants. Initially, network mapping was performed followed by performing a Bayesian random-effects model using the Markov chain Monte Carlo method. Areas under the cumulative ranking curve (SUCRA) were calculated as a measure of the probability that each intervention was likely to be the 1st, 2nd, 3rd, etc. best therapy. Primary outcome measure was death or moderate or severe neurodevelopmental outcome at or beyond 12 months of corrected age. Results: Ten different trials were identified, enrolling 700 individuals (449 for the primary outcome). Seven intervention categories were identified, and of the 15 possible pair comparisons, 6 have been studied directly. In the multiple-treatment meta-analysis, no comparison reached conventional levels of statistical significance. Drainage Irrigation and Fibrinolytic Therapy (DRIFT) had the highest probability of being the best treatment for the primary outcome (82.1%), followed by CSF removal (10.8%), conservative management (6.7%), and then diuretic therapy (0.4%). Conclusions: PHVD is a significant cause of death and disability in developed countries, yet few therapeutic options have so far been trialed. While new therapies are urgently needed for these infants, at present, NMA shows that DRIFT appears to be the most likely candidate to improve outcomes after sIVH.

‘Opportunity to bond and a sense of normality’:Parent and staff views of cuddling babies undergoing therapeutic hypothermia in neonatal intensive care: ‘CoolCuddle’

Abstract Background Currently, parents whose sick babies are undergoing three days of cooling therapy for hypoxic–ischaemic encephalopathy in neonatal intensive care units (NICUs) are not permitted to cuddle their cooled babies, due to concerns of warming the baby or dislodging breathing tubes or vascular catheters. Parents want to stay and care for their cooled babies and have reported that bonding is adversely affected when they are not permitted to hold them. Design and Participants Qualitative interviews with 21 parents of cooled babies in NICU (11 mothers and 10 fathers) and 10 neonatal staff (4 consultants and 6 nurses) explored their views and experiences of an intervention to enable parents to cuddle their cooled babies (CoolCuddle). Thematic analysis methods were used to develop the themes and compare them between parents and staff. Results Five themes were produced. Three themes were comparable between parents and staff: Closeness, a sense of normality and reassurance and support. An additional parent theme reflected their mixed feelings about initial participation as they were apprehensive, but felt that it was an amazing opportunity. Parents and staff described the closeness between parents and babies as important for bonding and breastfeeding. Fathers particularly appreciated the opportunity to hold and bond with their infants. Parents valued the reassurance and support received from staff, and the cuddles helped them feel more normal and more like a family at a very stressful time. In a final staff theme, they discussed the skills, number of staff and training needed to undertake CoolCuddle in NICU. Conclusions Parents cuddling their babies during cooling therapy enhanced parent–infant bonding and family‐centred care in NICU and was positively received. Adverse perinatal mental health, impaired mother–infant bonding and their effects on the establishment of breastfeeding may be ameliorated by introducing CoolCuddle. Patient Contribution Our parent advisors contributed to the interview topic guides and endorsed the themes from the analysis

The impact of a sepsis quality improvement project on neurodisability rates in very low birthweight infants

Objective Very low birthweight (VLBW; <1500 g) infants with late-onset sepsis (LOS) have an increased risk of neurodisability. Care bundles to reduce bloodstream infections in neonatal intensive care unit (NICU) are effective in reducing LOS. Our aim was to determine if a sepsis reduction bundle introduced through a quality improvement project would impact neurodevelopmental outcomes in VLBW infants. Design Cohort study. Setting Level 3 regional NICU in the South West of England. Patients VLBW infants born between 2002 and 2011. Interventions A sepsis reduction care bundle implemented between July 2006 and December 2007. Main outcome measures The primary outcome was risk of coagulase-negative Staphylococcus (CONS) infection diagnosed >3 days of age. Secondary outcomes were death and moderate cognitive impairment. A logistic regression model was derived using the birth era as the independent variable with adjustment for typical confounders. Results In total, 379 infants were born in the preintervention cohort and 378 in the postintervention cohort. The CONS infection rate was reduced after the intervention (26.7% vs 14.1% p<0.001). Death prior to discharge reduced without reaching statistical significance (14.1% vs10.9%, p=0.195). The rate of cognitive disability reduced in the postintervention cohort (18.8% vs 6.1%, p=0.042). The adjusted ORs (95% CI) for CONS infection, death and cognitive impairment were 0.46 (0.29 to 0.72), 0.73 (0.43 to 1.24) and 0.3 (0.07 to 1.33), respectively. Conclusions There appears to be an association between reduced cognitive disability and the implementation of a sepsis reduction bundle. Further study in larger series is required to confirm these findings

Association between neonatal resuscitation and a single nucleotide polymorphism rs1835740

© 2016 Foundation Acta Pædiatrica. Published by John Wiley & Sons Ltd. Aim The aim of this work was to test whether three single nucleotide polymorphisms (SNPs) implicated in glutamate homoeostasis or signalling and cellular survival are associated with birth condition. Methods This study is drawn from the Avon Longitudinal Study of Parents and Children. A total of 7611 term infants were genotyped and patient outcome data retrieved from routine medical records. Exposure measures were the presence of one or more minor alleles in one of 3 SNPs (rs2284411, rs2498804, rs1835740). The primary outcome was the need for resuscitation at birth. Results For SNP rs1835740, infants homozygous for the minor allele compared to wild type were more likely to need resuscitation (9.2% vs. 7.0%, p = 0.041), while the odds ratio for resuscitation was associated with each increasing minor allele [OR 1.17 (1.01-1.35)]. Population attributable risk fraction was 6.5%. There was no evidence that the other two SNPs investigated were associated with birth condition. Conclusion We have tested three candidate SNPs to measure any association with birth condition. The study revealed that the rs1835740 was associated with the need for resuscitation and Apgar scores, with a substantial population impact

Child suicide rates during the COVID-19 pandemic in England

BACKGROUND: There is concern about the impact of COVID-19, and the control measures to prevent the spread, on children's mental health. The aim of this work was to identify if there had been a rise of childhood suicide during the COVID pandemic. METHOD: Using data from England's National Child Mortality Database (NCMD) the characteristics and rates of children dying of suicide between April to December 2020 were compared with those in 2019. In a subset (1(st) January to 17(th) May 2020) further characteristics and possible contributing factors were obtained. RESULTS: A total of 193 likely childhood deaths by suicide were reported. There was no evidence overall suicide deaths were higher in 2020 than 2019 (RR 1.09 (0.80-1.48), p=0.584) but weak evidence that the rate in the first lockdown period (April to May 2020) was higher than the corresponding period in 2019 (RR 1.56 (0.86-2.81), p=0.144). Characteristics of individuals were similar between periods. Social restrictions (e.g. to education), disruption to care and support services, tensions at home and isolation appeared to be contributing factors. LIMITATIONS: As child suicides are fortunately rare, the analysis is based on small numbers of deaths with limited statistical power to detect anything but major increases in incidence. CONCLUSION: We found no consistent evidence that child suicide deaths increased during the COVID-19 pandemic although there was a possibility that they may have increased during the first UK lockdown. A similar peak was not seen during the following months, or the second lockdown

Detection of three closely located single nucleotide polymorphisms in the EAAT2 promoter: Comparison of single-strand conformational polymorphism (SSCP), pyrosequencing and Sanger sequencing

Background: Single-strand conformational polymorphism (SSCP) is still a frequently used genotyping method across different fields for the detection of single nucleotide polymorphisms (SNPs) due to its simplicity, requirement for basic equipment accessible in most laboratories and low cost. This technique was previously used to detect rs4354668:A > C (g.-181A > C) SNP in the promoter of astroglial glutamate transporter (EAAT2) and the same approach was initially used here to investigate this promoter region in a cohort of newborns.Results: Unexpectedly, four distinct DNA migration patterns were identified by SSCP. Sanger sequencing revealed two additional SNPs: g.-200C > A and g.-168C > T giving a rise to a total of ten EAAT2 promoter variants. SSCP failed to distinguish these variants reliably and thus pyrosequencing assays were developed. g.-168C > T was found in heterozygous form in one infant only with minor allele frequency (MAF) of 0.0023. In contrast, g.-200C > A and -181A > C were more common (with MAF of 0.46 and 0.49, respectively) and showed string evidence of linkage disequilibrium (LD). In a systematic comparison, 16% of samples were miss-classified by SSCP with 25-31% errors in the identification of the wild-type and homozygote mutant genotypes compared to pyrosequencing or Sanger sequencing. In contrast, SSCP and pyrosequencing of an unrelated single SNP (rs1835740:C > T), showed 94% concordance.Conclusion: Our data suggest that SSCP cannot always detect reliably several closely located SNPs. Furthermore, caution is needed in the interpretation of the association studies linking only one of the co-inherited SNPs in the EAAT2 promoter to human diseases. © 2014 Rajatileka et al.; licensee BioMed Central Ltd

Associations between birth at, or after, 41 weeks gestation and perinatal encephalopathy: a cohort study

Background Preterm birth causes long-term problems, even for infants born 1 or 2 weeks early. However, less is known about infants born after their due date and over a quarter of infants are born over 1 week late, and many still remain undelivered after 2 weeks. The aim of this work is to quantify the risks of infants developing encephalopathy when birth occurs after the due date, and if other proposed risk factors modify this relationship. Methods The dataset contain information on 4 036 346 infants born in Sweden between 1973 and 2012. Exposure was defined as birth 7, or more, days after the infants’ due date. The primary outcome was the development of neonatal encephalopathy (defined as seizures, encephalopathy or brain injury caused by asphyxia or with unspecified cause). Covariates were selected as presumed confounders a priori. Results 28.4% infants were born 1 or more weeks after their due date. An infant’s risk of being born with encephalopathy was higher in the post 41 weeks group in the unadjusted (OR 1.40 (95% CI 1.32 to 1.49)) and final model (OR 1.38 (95% CI 1.29 to 1.47)), with the relative odds of encephalopathy increasing by an estimated 20% per week after the due date, and modified by maternal age (P=0.022). Conclusions Singleton infants born at, or after, 41 weeks gestation have lower Apgar scores and higher risk of developing encephalopathy in the newborn period, and the association appeared more marked in older mothers. These data could be useful if provided to women as part of their decision-making

Prediction of school outcome after preterm birth:a cohort study

Objective To identify if the educational trajectories of preterm infants differ from those of their term peers. Design This work is based on the Avon Longitudinal Study of Parents and Children (ALSPAC). Educational measures were categorised into 10 deciles to allow comparison of measures across time periods. Gestational age was categorised as preterm (23–36 weeks) or term (37–42 weeks). Multilevel mixed-effects linear regression models were derived to examine the trajectories of decile scores across the study period. Gestational group was added as an interaction term to assess if the trajectory between educational measures varied between preterm and term infants. Adjustment for possible confounders was performed. Subjects The final dataset contained information on 12 586 infants born alive at between 23 weeks and 42 weeks of gestation. Main outcome measures UK mandatory educational assessments (SATs) scores throughout educational journal (including final GCSE results at 16 years of age). Results Preterm infants had on average lower Key Stage (KS) scores than term children (−0.46 (−0.84 to −0.07)). However, on average, they gained on their term peers in each progressive measure (0.10 (0.01 to 0.19)), suggesting ‘catch up’ during the first few years at school. Preterm infants appeared to exhibit the increase in decile scores mostly between KS1 and KS2 (p=0.005) and little between KS2 and KS3 (p=0.182) or KS3 and KS4 (p=0.149). Conclusions This work further emphasises the importance of early schooling and environment in these infants and suggests that support, long after the premature birth, may have additional benefits
