Increased Risk for Neurodevelopmental Disorders in Children With Orofacial Clefts

Psychosocial Issues Related to Speech and Hearing in Patients With Clefts

INTRODUCTION

Individuals with cleft lip and palate often face persistent challenges related to speech and hearing disorders, impacting various aspects of their lives. These challenges can lead to additional mental health issues such as attention-deficit/hyperactivity disorder, anxiety, and depression, as well as heightened psychosocial challenges, including appearance-related issues, bullying, workplace discrimination, and impaired social interactions. Children and adolescents with these disorders commonly experience loneliness, peer rejection, and challenges in forming friendships, particularly during adolescence, while voice disorders can diminish the quality of life in older individuals.

CASE DESCRIPTION

This case study focuses on a 17-year-old male with unilateral cleft lip and palate undergoing treatment in Medellin, Colombia, aiming to provide insights into the intricate psychosocial challenges linked to speech and hearing difficulties in individuals with cleft conditions.

DISCUSSION AND EVALUATION

Clinical evaluations identified significant challenges concerning speech difficulties and self-perception, influenced by the patient's cleft condition, which impacts his self-esteem, confidence, and social skills development. The interconnectedness between speech and hearing challenges underscores the necessity for comprehensive care to address the multifaceted psychosocial aspects experienced by individuals with cleft conditions.

CONCLUSIONS

This case study used as an example, indicates that speech difficulties and psychosocial challenges related to cleft conditions are experienced from childhood and may persist into adulthood. These challenges can have profound effects on various aspects of life, including school, social interactions, family dynamics, and even romantic relationships. Consequently, the lack of confidence, social isolation, and limited social skills may delay patients from reaching their fullest potential.

Interaction between Per- and Polyfluorinated Substances (PFAS) and Acetaminophen in Disease Exacerbation-Focusing on Autism and the Gut-Liver-Brain Axis

This review presents a new perspective on the exacerbation of autism spectrum disorder (ASD) by per- and polyfluoroalkyl substances (PFAS) through the gut-liver-brain axis. We have summarized evidence reported on the involvement of the gut microbiome and liver inflammation that led to the onset and exacerbation of ASD symptoms. As PFAS are toxicants that particularly target liver, this review has comprehensively explored the possible interaction between PFAS and acetaminophen, another liver toxicant, as the chemicals of interest for future toxicology research. Our hypothesis is that, at acute dosages, acetaminophen has the ability to aggravate the impaired conditions of the PFAS-exposed liver, which would further exacerbate neurological symptoms such as lack of social communication and interest, and repetitive behaviors using mechanisms related to the gut-liver-brain axis. This review discusses their potential interactions in terms of the gut-liver-brain axis and signaling pathways that may contribute to neurological diseases.

Exploring the roles of noncoding RNAs in craniofacial abnormalities: A systematic review

Congenital craniofacial abnormalities are congenital anomalies of variable expressivity and severity with a recognizable set of abnormalities, which are derived from five identifiable primordial structures. They can occur unilaterally or bilaterally and include various malformations such as cleft lip with/without palate, craniosynostosis, and craniofacial microsomia. To date, the molecular etiology of craniofacial abnormalities is largely unknown. Noncoding RNAs (ncRNAs), including microRNAs, long ncRNAs, circular RNAs and PIWI-interacting RNAs, function as major regulators of cellular epigenetic hallmarks via regulation of various molecular and cellular processes. Recently, aberrant expression of ncRNAs has been implicated in many diseases, including craniofacial abnormalities. Consequently, this review focuses on the role and mechanism of ncRNAs in regulating craniofacial development in the hope of providing clues to identify potential therapeutic targets.

Being Normal yet Different: A Qualitative Study on the Dualistic Experience of Living With Unilateral Cleft Lip and Palate

The aim of the present study was to describe the experiences of young adults living with cleft lip and palate (CLP) and to explore potential gender differences.

A descriptive qualitative study was designed involving semi-structured interviews. The interviews were analyzed using qualitative content analysis, as described by Graneheim and Lundman.

A total of 9 women and 8 men, aged 22 to 26 years with UCLP.

The main theme identified was: the duality of living with a cleft-being normal yet different, and 2 subcategories: "My cleft and me" and "My cleft and the World." The participants described themselves as normal yet different, both in relation to themselves and in relation to others. They also stated that gender norms regarding appearance affected their lives and how they saw the cleft.

This study adds to the growing body of qualitative research on CLP. It highlights the dualistic experiences of feeling normal and different at the same time. The interviews indicated that this dualism was based on context and gender, showing the psychological complexity of an individual. The clinical implications of this study emphasizes the need of a person-centered care approach in the cleft care setting where the clinicians are aware of the potential dualistic experience that also may differ over time that individuals with cleft can experience. This can also help clinicians better understand and help patients reduce distress and strengthen positive coping mechanisms.

Classification Systems of Cleft Lip, Alveolus and Palate: Results of an International Survey

OBJECTIVE

This study aimed to identify commonly used classification systems by cleft providers around the world, including the perceived indications and limitations of each system.

DESIGN

A cross-sectional survey.

PARTICIPANTS

A total of 197 registrants from three international cleft/craniofacial meetings.

INTERVENTIONS

Participants were sent a web-based questionnaire concerning cleft classification systems.

MAIN OUTCOME MEASURES

Frequency of commonly used classification systems, their perceived indications and limitations.

RESULTS

A total of 197 respondents from 166 different centers completed the questionnaire. Healthcare professionals from all disciplines responded, with the most frequent respondents being plastic surgeons (38.1%), maxillofacial surgeons (28.4%) and orthodontists (23.9%). Eighteen different classification systems were in use. The most frequently used systems were the International Statistical Classification of Diseases and Related Health Problems (ICD-10) (35.5%), LAHSHAL (34.0%), and Veau (32.5%) classification systems. Most respondents (32.5%) indicated that anatomical and morphological characteristics are essential components of a classification system. However, respondents indicated that their current classification systems lacked sufficient description of cleft extension and severity.

CONCLUSIONS

Great variety in the use of classification systems exists among craniofacial specialists internationally. The results recommend the usage of the LAHSHAL classification of OFCs, due to its comprehensiveness, relatively high implementation rate globally, convenience of usage and complementarity with the ICD-10 system. Moreover, it can overcome deficiencies inextricably linked to ICD-10, such as incapacity to describe laterality and clefts of the alveolus. More international exposure to the merits of using the LAHSHAL classification system would be highly recommended.

Cognitive functioning and clinical characteristics of children with non-syndromic orofacial clefts: A case-control study

Introduction

The higher rate of neuropsychiatric disorders in individuals with non-syndromic orofacial clefts has been well documented by previous studies. Our goal was to identify children with non-syndromic orofacial clefts that are at risk for abnormal neurodevelopment by assessing their developmental history and present cognitive functioning.

Materials and methods

A single-center, case-controlled study was carried out at the Department of Pediatrics of the University of Pécs in Hungary. The study consisted of three phases including questionnaires to collect retrospective clinical data and psychometric tools to assess IQ and executive functioning.

Results

Forty children with non-syndromic oral clefts and 44 age-matched controls participated in the study. Apgar score at 5 min was lower for the cleft group, in addition to delays observed for potty-training and speech development. Psychiatric disorders were more common in the cleft group (15%) than in controls (4.5%), although not statistically significant with small effect size. The cleft group scored lower on the Continuous Performance Test. Subgroup analysis revealed significant associations between higher parental socio-economic status, academic, and cognitive performance in children with non-syndromic orofacial clefts. Analyzes additionally revealed significant associations between early speech and language interventions and higher scores on the Verbal Comprehension Index of the WISC-IV in these children.

Discussion

Children with non-syndromic orofacial clefts seem to be at risk for deficits involving the attention domain of the executive system. These children additionally present with difficulties that affect cognitive and speech development. Children with non-syndromic orofacial clefts show significant skill development and present with similar cognitive strengths as their peers. Longitudinal studies with larger sample sizes are needed to provide more conclusive evidence on cognitive deficits in children with non-syndromic orofacial clefts at risk for neurodevelopmental difficulties.

Developmental implications of genetic testing for physical indications

In children undergoing genetic testing for physical health concerns, we examined how often the results also revealed information about their risk for neurodevelopmental disorders. The study sample consisted of 3056 genetic tests (1686 chromosomal microarrays--CMAs, and 1378 next-generation sequencing--NGS panels) ordered at a tertiary pediatric hospital because of a physical/congenital health problem. Tests ordered to investigate developmental concerns were excluded. Pathogenic, or likely pathogenic variants were manually reviewed for diagnostic likelihood, and for evidence of an association with a neurodevelopmental disorder (e.g., autism or intellectual disability). A total of 169 CMAs (10%) and 232 NGS panels (17%) had likely diagnostic results. More than half (52%) of all diagnostic results had established evidence of a neurodevelopmental disorder association. In summary, there is a high prevalence of neurodevelopmental implications from genetic tests ordered for physical/congenital indications. This broad clinical utility suggests a growing need for genetics-first developmental care pathways.

The Prevalence of Social Withdrawal in Infants With Cleft Lip and Palate: The Feasibility of the Full and the Modified Versions of the Alarm Distress Baby Scale

Background

Social withdrawal is a risk indicator for infant development with both organic and non-organic causes. Cleft lip and palate (CLP) impose a higher risk of physical and emotional distress in infants and alters parent-infant relationships. The ADBB scale is a screening tool to identify social withdrawal as a sign of distress in infants. The aim of this study is to evaluate the prevalence of social withdrawal behavior in infants with CLP using the full 8-item ADBB scale and the modified 5-item ADBB scale, and to examine the feasibility of both scales.

Methods

145 infants with Cleft Lip and Palate were enrolled and video recorded during a pediatric consultation. All infants were scored by two expert raters trained in ADBB scale, and subsequently scored with the m-ADBB by an independent expert. We measured the interrater agreement for the full ADBB scale and psychometric properties of both scales.

Results

The full ADBB scale identified 15.9% of infants as having social withdrawal behavior (score above cutoff ≥5). Among the infants evaluated with the m-ADBB scale, 44.9% had a score above the suggested cutoff (≥2). For both scales, the item "vocalization" showed the higher scores. We found a good internal consistency for the full ADBB (Cronbach's alpha = 0.82) and an acceptable internal consistency for the modified ADBB (Cronbach's alpha = 0.71). The interrater agreement for the full ADBB scale was excellent (kappa = 0.837). The Spearman correlation coefficient between the total scores of the two versions was 0.88 (P < 0.001).

Conclusion

Our results indicate a relatively high prevalence of social withdrawal in infants with Cleft Lip and Palate, especially evaluated with the modified 5-item ADBB scale. We found that the full ADBB and the modified ADBB scales are feasible to use as screening tools of social withdrawal in this population.

The Brain in Oral Clefting: A Systematic Review With Meta-Analyses

Background

Neuroimaging of individuals with non-syndromic oral clefts have revealed subtle brain structural differences compared to matched controls. Previous studies strongly suggest a unified primary dysfunction of normal brain and face development which could explain these neuroanatomical differences and the neuropsychiatric issues frequently observed in these individuals. Currently there are no studies that have assessed the overall empirical evidence of the association between oral clefts and brain structure. Our aim was to summarize the available evidence on potential brain structural differences in individuals with non-syndromic oral clefts and their matched controls.

Methods

MEDLINE, Scopus, Cochrane Central Register of Controlled Trials, Web of Science and Embase were systematically searched in September 2020 for case-control studies that reported structural brain MRI in individuals with non-syndromic oral clefts and healthy controls. Studies of syndromic oral clefts were excluded. Two review authors independently screened studies for eligibility, extracted data and assessed risk of bias with the Newcastle-Ottawa Scale. Random effects meta-analyses of mean differences (MDs) and their 95% confidence intervals (95% CI) were performed in order to compare global and regional brain MRI volumes.

Results

Ten studies from 18 records were included in the review. A total of 741 participants were analyzed. A moderate to high risk of bias was determined for the included studies. The cerebellum (MD: -12.46 cm3, 95% CI: -18.26, -6.67, n = 3 studies, 354 participants), occipital lobes (MD: -7.39, 95% CI: -12.80, -1.99, n = 2 studies, 120 participants), temporal lobes (MD: -10.53 cm3, 95% CI: -18.23, -2.82, n = 2 studies, 120 participants) and total gray matter (MD: -41.14 cm3; 95% CI: -57.36 to -24.92, n = 2 studies, 172 participants) were significantly smaller in the cleft group compared to controls.

Discussion

There may be structural brain differences between individuals with non-syndromic oral clefts and controls based on the available evidence. Improvement in study design, size, methodology and participant selection could allow a more thorough analysis and decrease study heterogeneity.

Association of cumulative early medical factors with autism and autistic symptoms in a population-based twin sample

Although highly heritable, environment also contributes to the etiology of autism spectrum disorder (ASD), with several specific environmental factors previously suggested. A registry-linked population-based twin cohort of 15,701 pairs (586 individuals with an ASD diagnosis), was established within the Child and Adolescent Twin Study in Sweden. Participants were evaluated for autistic symptoms at age 9 using the Autism-Tics, ADHD and other Comorbidities parental interview. A series of binary cut-offs indicated whether participants scored over various ASD symptom percentiles. Three early medical factors previously associated with ASD, beyond familial confounding (low birth weight, congenital malformations and perinatal hypoxia), were summed up creating an individual cumulative exposure load. A series of unconditional logistic regressions between all individuals and conditional regressions within twin pairs were performed for each outcome and exposure level. Between all individuals increasing cumulative early exposure loads were associated with increasing risk of ASD diagnosis (OR 3.33 (95%CI 1.79-6.20) for three exposures) and autistic symptoms (ranging from OR 2.12 (1.57-2.86) for three exposures at the 55th symptom percentile cut-off to OR 3.39 (2.2-5.24) at the 95th). Within twin pairs, the association between three exposures and an ASD diagnosis remained similar, but not statistically significant (OR 2.39 (0.62-9.24)). Having a higher load of early cumulative exposure was consistently associated with autistic symptoms after adjusting for familial confounding and sex (OR 3.45 (1.66-7.15) to OR 7.36 (1.99-27.18)). This study gives support to the cumulative stress hypothesis of ASD, and the dimensional model regarding environmental exposures, after adjustment for familial confounding.

Clinical and Descriptive Study of Orofacial Clefts in Colombia: 2069 Patients From Operation Smile Foundation

OBJECTIVE

To describe the population of patients with cleft lip and/or palate (CL/P) in terms of cleft phenotypes, gender, age, ethnic group, family history, clinical presentation (syndromic vs nonsyndromic), some environmental and behavioral factors, and some clinical features.

DESIGN

Descriptive retrospective study.

SETTING

Patients attending the genetics counseling practice in Operation Smile Foundation, Bogotá, Colombia, for over 8 years.

PARTICIPANTS

No screening was conducted. All patients requiring clinical genetics assessment in Operation Smile Foundation were included in the study.

RESULTS

Left cleft lip and palate (CLP) and nonsyndromic forms were the most frequent types of malformations in this population. Psychomotor retardation and heart disease were the most frequent comorbidities in these patients. A low proportion of mothers exposed to passive smoking during pregnancy was observed and low birth weight accounted for an important number of cases. Aarskog, velocardiofacial, and orofaciodigital syndromes were the most frequent syndromic forms of CLP in this population.

CONCLUSIONS

In this study, the most frequent type of CL/P was the nonsyndromic complete left CLP. Aarskog, velocardiofacial, and orofaciodigital syndromes were the most frequent syndromic forms of CL/P in this population.

Prenatal Exposure to Per- and Polyfluoroalkyl Substances and Facial Features at 5 Years of Age: A Study from the Danish National Birth Cohort

BACKGROUND

Per- and polyfluoroalkyl substances (PFAS) are widespread persistent pollutants. Evidence regarding neurodevelopmental effects of PFAS have been mixed. The relation between PFAS exposure and anatomical markers that have been suggested to correlate with fetal brain development have not been studied.

OBJECTIVES

We investigated the association between prenatal PFAS exposures and three craniofacial features in children measured at 5 years of age.

METHODS

Measures of palpebral fissure length (PFL), philtrum groove, and upper-lip thickness were generated from standardized digital facial photographs from 656 children in the Danish National Birth Cohort. PFL was classified into two groups (shorter; normal), and the philtrum (grooved; smooth; normal) and upper-lip (thick; thin; normal) measures into three groups each. Six PFAS were measured in maternal plasma (median=8 gestational wk). Multinomial logistic regression was used to estimate the odds ratio (OR) and 95% confidence interval (CI) for each facial feature using the normal group as the reference according to log2-PFAS concentration (in nanograms per milliliter) or PFAS tertiles, adjusting for potential confounders, including maternal alcohol intake and smoking. Stratified analyses by maternal alcohol intake or child's sex were performed.

RESULTS

Prenatal exposure to each PFAS was associated with elevated odds for a shorter PFL, with the strongest association observed for perfluorodecanoic acid (PFDA; per doubling OR=2.02; 95% CI: 1.11, 3.70). Some nonlinear associations were found for philtrum measures: the second tertile of PFDA and perfluorononanoic acid were associated with grooved philtrum, whereas the second tertile of perfluoroheptane sulfonate with smooth philtrum. The associations between PFAS exposure and a shorter PFL were stronger among mothers who consumed alcohol in the first trimester, some sex-specific associations were noted for philtrum and upper-lip measures.

DISCUSSION

Prenatal PFAS exposures might influence fetal craniofacial development. A larger study is needed to replicate the potential modifying effects observed for alcohol exposure and to clarify whether associations of craniofacial markers observed reflect specific neurologic deficits. https://doi.org/10.1289/EHP9478.

Association between craniofacial anomalies, intellectual disability and autism spectrum disorder: Western Australian population-based study

BACKGROUND

Accurate knowledge of the relationship between craniofacial anomalies (CFA), intellectual disability (ID) and autism spectrum disorder (ASD) is essential to improve services and outcomes. The aim is to describe the association between CFA, ID and ASD using linked population data.

METHODS

All births (1983-2005; n = 566,225) including CFA births (comprising orofacial clefts, craniosynostosis, craniofacial microsomia and mandibulofacial dysostosis) surviving to 5 years were identified from the birth, death, birth defects and midwives population data sets. Linked data from these data sets were followed for a minimum of 5 years from birth until 2010 in the intellectual disability database to identify ID and ASD. These associations were examined using a modified Poisson regression.

RESULTS

Prevalence of ID and ASD was higher among CFA (especially with additional anomalies) than those without [prevalence ratio 5.27, 95% CI 4.44, 6.25]. It was higher among CFA than those with other gastrointestinal and urogenital anomalies but lower than nervous system and chromosomal anomalies. Children with CFA and severe ID had a higher proportion of nervous system anomalies.

CONCLUSIONS

Findings indicate increased ID and ASD among CFA but lower than nervous system and chromosomal anomalies. This population evidence can improve early identification of ID/ASD among CFA and support service planning.

IMPACT

Our study found about one in ten children born with craniofacial anomalies (CFA) are later identified with intellectual disability (ID). Prevalence of ID among CFA was higher than those with other gastrointestinal, urogenital, and musculoskeletal birth defects but lower than those with the nervous system and chromosomal abnormalities. Most children with craniofacial anomalies have a mild-to-moderate intellectual disability with an unknown aetiology. On average, intellectual disability is identified 2 years later for children born with non-syndromic craniofacial anomalies than those with syndromic conditions. Our findings can improve the early identification of ID/ASD among CFA and support service planning.

Validity Prediction of Amplitude-Integrated EEG in Early Neuromotor Development Outcomes in High-Risk Neonates

With the continuous advancement of medical technology, the survival rate of high-risk children is increasing year by year, but the developmental problems that have gradually become apparent in the later stages have a serious impact on the quality of life of children. Amplitude-integrated EEG is an EEG monitoring technology developed for clinical use in newborns in recent years. Therefore, to better detect neuromata development in high-risk children, this study explores the validity prediction of amplitude-integrated EEG in early neuromata development in high-risk children. For 100 high-risk children, amplitude-integrated EEG was used for monitoring, and the exercise scale and validity predictors in the Bailey Infant Development Scale were used to assess whether high-risk children had neurobehavioral abnormalities. The experimental results show that the application of amplitude-integrated EEG can make accurate and effective predictions of early neuromata development outcomes in high-risk children. Compared with traditional neurological examination methods, it has higher sensitivity, specificity, positive predictive value, and consistency in predicting the early neuromata development outcomes of high-risk children. It is suitable for application and promotion in China and has a good application value.

Identification of New miRNA-mRNA Networks in the Development of Non-syndromic Cleft Lip With or Without Cleft Palate

Objective: To identify new microRNA (miRNA)-mRNA networks in non-syndromic cleft lip with or without cleft palate (NSCL/P).

Materials and Methods: Overlapping differentially expressed miRNAs (DEMs) were selected from cleft palate patients (GSE47939) and murine embryonic orofacial tissues (GSE20880). Next, the target genes of DEMs were predicted by Targetscan, miRDB, and FUNRICH, and further filtered through differentially expressed genes (DEGs) from NSCL/P patients and controls (GSE42589), MGI, MalaCards, and DECIPHER databases. The results were then confirmed by in vitro experiments. NSCL/P lip tissues were obtained to explore the expression of miRNAs and their target genes.

Results: Let-7c-5p and miR-193a-3p were identified as DEMs, and their overexpression inhibited cell proliferation and promoted cell apoptosis. PIGA and TGFB2 were confirmed as targets of let-7c-5p and miR-193a-3p, respectively, and were involved in craniofacial development in mice. Negative correlation between miRNA and mRNA expression was detected in the NSCL/P lip tissues. They were also associated with the occurrence of NSCL/P based on the MGI, MalaCards, and DECIPHER databases.

Conclusions: Let-7c-5p-PIGA and miR-193a-3p-TGFB2 networks may be involved in the development of NSCL/P.

Parent-reported socioemotional and cognitive development in children with a cleft lip and/or palate at 18 months: Findings from a UK birth cohort

BACKGROUND

One of the most common congenital conditions in the world, cleft lip and/or palate (CL/P) has been shown to potentially impact long-term physical and developmental outcomes in affected children. However, little is known about the factors that contribute to such outcomes, and there is a lack of consensus about which screening tools may be most effective. The aims of the current study were (a) to assess parent-reported socioemotional and cognitive development in children born with CL/P at 18 months of age; (b) to identify factors associated with the incidence of developmental concerns; and (c) to assess the utility of the widely recommended Ages and Stages Questionnaires (ASQs) in identifying developmental concerns from an early age in the CL/P population.

METHODS

Parent-reported questionnaire data were extracted from The Cleft Collective Cohort Study for 322 mothers of children with CL/P aged 18 months.

RESULTS

Mean scores across both ASQ measures indicated typical development in the study sample overall. However, 31.1% of children met a referral criterion on at least one domain. Child-related risk factors included problems with physical development and feeding method. Parent-related risk factors included the mother's levels of anxiety and depression and mother's marital status. Additional developmental concerns extracted from mothers' qualitative data included feeding difficulties, speech development, sleep patterns, aggressive behaviours, vision, oral health, hearing, breathing and motor skills.

CONCLUSIONS

The majority of children in this study were developing as expected at 18 months of age. However, parent-reported developmental concerns were identified in a minority of children, suggesting a need to screen for potential risk factors in routine practice. Further, the ASQ appears to offer a viable option in the early identification of developmental concerns in children with CL/P. A combined medical and systemic approach to healthcare is recommended to support the prevention of long-term developmental concerns in the child and poor psychological adjustment in parents.

Efficacy and Safety in Combining Primary Palatoplasty and Myringotomy in Patients with Cleft Palate

Patients born with a cleft lip and palate undergo multiple surgical procedures, increasing the infants’ exposure to anesthesia and potential risk of neurocognitive delays. In addition, these numerous procedures lead to greater use of hospital resources. This study analyzes the differences in anesthetic exposure and perioperative characteristics between performing combined versus separate primary palatoplasty (PP) and placement of bilateral myringotomy tubes (BMT).

Nonsyndromic Craniosynostosis Is Associated with Increased Risk for Psychiatric Disorders

BACKGROUND

Craniosynostosis is one of the most common craniofacial malformations demanding surgical treatment in infancy. Data on overall psychiatric morbidity among children with nonsyndromic craniosynostosis remain limited. This study investigated the risk of psychiatric disorders in nonsyndromic craniosynostosis.

METHODS

The authors reviewed a register-based cohort of all individuals born with nonsyndromic craniosynostosis in Sweden between 1973 to 1986 and 1997 to 2012 (n = 1238). The nonsyndromic craniosynostosis cohort was compared with a matched community cohort (n = 12,380) and with unaffected full siblings (n = 1485). The authors investigated the risk of psychiatric disorders, suicide attempts, and suicides by using Cox regression adjusted for perinatal and somatic factors, season and birth year, sex, parental socioeconomic factors, and parental psychiatric disorders.

RESULTS

Children with nonsyndromic craniosynostosis had a higher risk of any psychiatric disorder (adjusted Cox-derived hazard ratio, 1.70; 95 percent CI, 1.43 to 2.02), including intellectual disability (adjusted Cox-derived hazard ratio, 4.96; 95 percent CI, 3.20 to 7.70), language disorders (adjusted Cox-derived hazard ratio, 2.36; 95 percent CI, 1.57 to 3.54), neurodevelopmental disorders (adjusted Cox-derived hazard ratio, 1.30; 95 percent CI, 1.01 to 1.69), and other psychiatric disorders (adjusted Cox-derived hazard ratio, 1.43; 95 percent CI, 1.11 to 1.85). Full siblings with nonsyndromic craniosynostosis were more likely, in the crude analyses, to be diagnosed with any psychiatric disorder, including intellectual disability, language disorders, and neurodevelopmental disorders compared with nonaffected siblings. The higher risk for any psychiatric disorder and intellectual disability remained after adjusting for confounders.

CONCLUSIONS

Children with nonsyndromic craniosynostosis demonstrated higher risks of any psychiatric disorder compared with children without nonsyndromic craniosynostosis. This risk cannot fully be explained by familial influences (i.e., genetic or environmental factors).

CLINICAL QUESTION/LEVEL OF EVIDENCE

Risk, III.

Early environmental risk factors for neurodevelopmental disorders - a systematic review of twin and sibling studies

While neurodevelopmental disorders (NDDs) are highly heritable, several environmental risk factors have also been suggested. However, the role of familial confounding is unclear. To shed more light on this, we reviewed the evidence from twin and sibling studies. A systematic review was performed on case control and cohort studies including a twin or sibling within-pair comparison of neurodevelopmental outcomes, with environmental exposures until the sixth birthday. From 7,315 screened abstracts, 140 eligible articles were identified. After adjustment for familial confounding advanced paternal age, low birth weight, birth defects, and perinatal hypoxia and respiratory stress were associated with autism spectrum disorder (ASD), and low birth weight, gestational age and family income were associated with attention-deficit/hyperactivity disorder (ADHD), categorically and dimensionally. Several previously suspected factors, including pregnancy-related factors, were deemed due to familial confounding. Most studies were conducted in North America and Scandinavia, pointing to a global research bias. Moreover, most studies focused on ASD and ADHD. This genetically informed review showed evidence for a range of environmental factors of potential casual significance in NDDs, but also points to a critical need of more genetically informed studies of good quality in the quest of the environmental causes of NDDs.

The impact of having a baby with cleft lip and palate on parents and on parent-baby relationship: the first French prospective multicentre study

BACKGROUND

The objective of this prospective, multidisciplinary and multicenter study was to explore the effect of a cleft lip, associated or not with a cleft palate, on parents, on parent-infant relationship, and on the baby's relational development. It also highlighted how the type of cleft and the timing of the surgery could impact this effect.

METHOD

158 infants, with Cleft lip with or without Palate, and their parents participated in this multicenter prospective cohort. Clinical evaluations were performed at 4 and 12 months postpartum. The impact on the parents and on the parent-infant relationship was evaluated by the Parenting Stress Index (PSI), the Edinburgh Post-partum Depression Scale (EPDS) and the Impact-on-Family Scale (IOFS). The relational development of the infant was assessed using the Alarm Distress Baby Scale (ADBB). The main criteria used to compare the infants were the severity of cleft and the time of surgery.

RESULTS

The timing of surgery, the type of malformation or the care structure had no effect on social withdrawal behaviors of the child at 4 and 12 months postpartum (ADBB). Furthermore, early intervention significantly decreased maternal stress assessed with the PSI at 4 months. Parents for whom it had been possible to give a prenatal diagnosis were much better prepared to accept the waiting time between birth and the first surgical intervention (IOFS). Higher postpartum depression scores (EPDS) were found for both parents compared to the general population.

CONCLUSION

A joint assessment of the mental health of both infants and parents is required in the follow-up of cleft lip and palate. Even if most families are remarkably resilient faced with this major cause of stress, a significant proportion of them could require help to deal with the situation, especially during this first year of follow-up. An assessment of the child's social withdrawal behaviour and of the parental stress and depression appears useful, in order to adapt care to infant and parent's needs.

Variants in miRNA regulome and their association with the risk of nonsyndromic orofacial clefts

Aim: To investigate the associations between single nucleotide polymorphisms (SNPs) in miRNA regulome and nonsyndromic orofacial clefts. Materials & methods: The associations were evaluated by logistic regression model in stage I (504 cases and 455 controls) and stage II (1500 cases and 1386 controls). Functional experiments including luciferase activity assay, cell apoptosis and proliferation, serum miRNA expression, and mouse embryo RNA sequencing were performed. Results: Rs3830766 in the enhancer of hsa-miR-4260 was associated with cleft lip only (CLO) and enhancer activity. Hsa-miR-4260 expression decreased in the serum of CLO. Overexpression of miR-4260 inhibited cell proliferation and promoted cell apoptosis. UBB was the target gene of hsa-miR-4260. Conclusion: Rs3830766 in the hsa-miR-4260 enhancer that can interact with UBB was relevant to CLO.

Assessing speech at three years of age in the cleft palate population: a scoping review of assessment practices

BACKGROUND

There is no consensus in the UK regarding the types of speech samples or parameters of speech that should be assessed at 3 years of age in children with cleft palate ± cleft lip (CP±L), despite cleft units routinely assessing speech at this age. The standardization of assessment practices would facilitate comparisons of outcomes across UK cleft units; earlier identification of speech impairments-which could support more timely treatments; and more reliable recording of therapy impacts and surgical interventions.

AIMS

To explore assessment practices used to assess speech in 3-year-old children with CP±L, including speech parameters, methods of assessment and the nature of the speech sample used.

METHODS & PROCEDURES

A broad examination of the literature was undertaken through the use of a scoping review conducted in accordance with Joanna Briggs Institute guidelines. Search terms were generated from a preliminary search and then used in the main search (Medline, CINAHL, Embase, AMED and PsycINFO).

MAIN CONTRIBUTION

A combination of approaches (medical, linguistic, developmental and functional) is required to assess CP±L speech at age 3. A developmental approach is recommended at this age, considering the complexity of speech profiles at age 3, in which typically developing speech processes may occur alongside cleft speech characteristics. A combined measure for both nasal emission and turbulence, and an overall measure for velopharyngeal function for speech, show potential for assessment at this age. Categorical ordinal scales are frequently used; the use of continuous scales has yet to be fully explored at age 3. Although single-word assessments, including a subset of words developed for cross-linguistic comparisons, are frequently used, more than one type of speech sample may be needed to assess speech at this age validly. The lack of consensus regarding speech samples highlights a need for further research into the types of speech samples 3-year-olds can complete; the impact of incomplete speech samples on outcome measures (particularly relevant at this age when children may be less able to complete a full sample); the impact of different speech samples on the validity of assessments; and the reliability of listener judgements.

CONCLUSIONS & IMPLICATIONS

Whilst a medical model and linguistic approaches are often central in assessments of age-3 cleft speech, this review highlights the importance of developmental and functional approaches to assessment. Cross-linguistic single-word assessments show potential, and would facilitate the comparison of UK speech outcomes with other countries. Further research should explore the impact of different speech samples and rating scales on assessment validity and listener reliability.

Folate Deficiency Based Autism as an Orofacial Clefts/Neural Tube Defect Spectrum Disorder

I would like to reply to the article "Increased Risk for Neurodevelopmental Disorders in Children With Orofacial Clefts" by Tillman et al.¹.

We read with interest the commentary of Dr. Zablow¹ on our publication on neurodevelopmental disorders and orofacial clefts (OFC).².

Orofacial Clefts May Be a Window Into Identifying Common Psychopathology Development

The research supporting a connection between physical and psychiatric illness continues to grow and advance. For example, there is continued work to identify whether this is due to connected brain pathology or to psychosocial stressors that inherently come with having another illness. Congenital illnesses may represent a window into our better understanding this connection, as the defect during embryogenesis that leads to the illness is sometimes known. Oral facial clefts (OCF) represent a congenital malformation that is well suited to study this question, as it is a common congenital condition and there are studies showing the increased prevalence of psychiatric comorbidities for those with OFC.¹ Of all patients with OFC, 70% are nonsyndromic, meaning they do not have an associated genetic syndrome leading to the development of the OFC.² There are three different types of OFC-cleft lip, cleft lip and palate, and cleft palate only-but it has been shown that all three seem to be associated with an increased risk for psychiatric illness. The timing of when OFC is believed to develop reflects a period when cells are differentiating from the neural tube, and thus a critical period in brain development.³ Some risk factors for developing OFC, such as alcohol use, antiepileptics, and smoking, may also affect brain development and are also associated with risk for the development of psychiatric disorders. What previous studies of OFC and psychiatric comorbidities have not been able to do is to control for other potential causes of OFC, especially familial risks.
