Abstract Background Various techniques in assisted reproductive technology (ART) have been developed as solutions for specific infertility problems. It is important to gain consensual conclusions on the actual risks of neurodevelopmental disorders among children who are born from ART. This study aimed to quantify the relative risks of cerebral palsy, intellectual disability, autism spectrum disorder (ASD), and behavioral problems in children from different ART methods by using systematic review and meta-analysis. Healthcare providers could use the results of this study to suggest the suitable ART technique and plan optimum postnatal care. Methods Pubmed, Google Scholar, and Scopus databases were used to search for studies up to January 2020. Of the 181 screened full manuscripts, 17 studies (9.39%) fulfilled the selection criteria. Based on the Newcastle-Ottawa scale ratings, 7 studies were excluded, resulting in 10 studies that were eventually included in the meta-analyses. Mantel-Haenszel risk ratio model was used in the meta-analysis, and the results are described using forest plot with 95% confidence interval. Heterogeneity was assessed using the I2 value. Results Pooled evaluation of 10 studies showed that the risk of cerebral palsy in children from assisted reproductive technology (ART) is higher than children from natural conceptions (risk ratio [RR] 1.82, [1.41, 2.34]; P = 0.00001). Risk of intellectual disability (RR 1.46, [1.03, 2.08]; P = 0.03) and ASD (RR 1.49 [1.05, 2.11]; P = 0.03) are higher in intracytoplasmic sperm injection (ICSI) children compared to conventional in vitro fertilization (IVF) children. The differences in the risk of neurodevelopmental disorders in children born after frozen and fresh embryo transfers are not significant. Analysis on potential cofounder effects, including multiple birth, preterm birth, and low birth body weight highlight possibilities of significant correlation to the risks of neurodevelopmental disorders. Conclusions Pooled estimates suggest that children born after ART are at higher risk of acquiring cerebral palsy. ICSI treatment causes higher risk of intellectual disability and ASD. These findings suggest the importance of the availability of intensive care unit at the time of delivery and long-term developmental evaluation particularly in children from ICSI.

Abstract Study Objectives Sleep disturbances are common and associated with negative functional and health consequences in children with neurological and neurodevelopmental disorders (NNDDs) and represent an important potential target for behavioral interventions. This systematic review examined the efficacy of behavioral sleep interventions (BSIs) for children with NNDDs and comorbid sleep disturbances. Methods A systematic search of MEDLINE, EMBASE, PsychINFO, and CENTRAL was conducted in April 2019. Randomized controlled trials (RCTs) of BSI for children with NNDDS were included. Meta-analysis and GRADE quality ratings were performed on sleep and secondary functional outcomes (cognition, academics, and behavior). Results Nine RCTs were identified (n = 690; Mage = 8.39 ± 2.64years; 71.11% male). The quality of the evidence was predominantly rated as moderate. Posttreatment improvements in sleep were found on self-reported sleep disturbances (total sleep disturbance [standardized mean difference, i.e. SMD = 0.89], night wakings [SMD = 0.52], bedtime resistance [SMD = 0.53], parasomnias [SMD = 0.34], sleep anxiety [SMD = 0.50]) and self-reported sleep patterns (sleep duration [SMD = 0.30], sleep onset duration [SMD = 0.75]) and (2) objectively measured actigraphic sleep patterns (total sleep time [MD = 18.09 min; SMD = 0.32], sleep onset latency [MD = 11.96 min; SMD = 0.41]). Improvements in sleep (self-reported, not actigraphy) were maintained at follow-up, but few studies conducted follow-up assessments resulting in low-quality evidence. Reduction in total behavioral problems (SMD = 0.48) posttreatment and attention/hyperactivity (SMD = 0.28) at follow-up was found. Changes in cognition and academic skills were not examined in any studies. Conclusions BSIs improve sleep, at least in the short term, in children with NNDDs. Benefits may extend to functional improvements in behavior. More rigorous RCTs involving placebo controls, blinded outcome assessment, longer follow-up durations, and assessment of functional outcomes are required.

The Impact

Abstract Background Fever during pregnancy is a relatively common and most often trivial event. However, under specific conditions, it could affect significantly fetal brain development. Few studies, with inconsistent results, investigated whether fever, regardless the pathogen, could represent a risk factor for neurodevelopmental disorders (NDD) in the offspring. We aimed to explore further this question by performing a systematic review and meta-analysis. Methods Peer-reviewed studies exploring the occurrence of NDD in offspring after a fetal exposure to maternal fever were included. We specifically considered the impact of fever severity and duration, taking into consideration some confounding variables such as the use of antipyretic during pregnancy, the trimester in which the fever arose, the maternal age or smoking at time of gestation. MEDLINE, EMBASE, PsycINFO, Cochrane and Web of Science were searched without language restriction. PRISMA recommendations were followed. Odds ratio (OR) were pooled using random-effects meta-analysis. Heterogeneity in effect size across studies was studied using random-effects meta-regression analysis. (PROSPERO CRD42020182801). Results We finally considered ten studies gathering a total of 10,304 children with NDD. Among them, 1394 were exposed to fever during pregnancy. The selected studies were divided into 5 case–control studies and 5 cohort studies. Maternal exposure to fever during pregnancy increased the risk of NDD in offspring with an OR of 1.24 [95% CI: 1.12–1.38]. Secondary analysis revealed an increased risk for NDD when fever occurred during the first trimester of gestation [OR 1.13–95% CI: 1.02–1.26]. Limitations We excluded studies that considered infections with no evidence of fever. Another potential limitation may be the possible heterogeneity between study designs (cohorts and case–control). Conclusion Additional evidence supported the association between fever during pregnancy and increased risk for NDD in offspring. Careful monitoring should be considered for children born from mothers with a febrile episode during pregnancy (specifically during the first trimester).
