Poverty and Risk of Cleft Lip and Palate: An Analysis of United States Birth Data

Combining lipidomics and machine learning to identify lipid biomarkers for nonsyndromic cleft lip with palate

Nonsyndromic cleft lip with palate (nsCLP) is a common birth defect disease. Current diagnostic methods comprise fetal ultrasound images, which are mainly limited by fetal position and technician skills. We aimed to identify reliable maternal serum lipid biomarkers to diagnose nsCLP. Eight-feature selection methods were used to assess the dysregulated lipids from untargeted lipidomics in a discovery cohort. The robust rank aggregation algorithm was applied on these selected lipids. The data were subsequently processed using 7 classification models to retrieve a panel of 35 candidate lipid biomarkers. Potential lipid biomarkers were evaluated using targeted lipidomics in a validation cohort. Seven classification models and multivariate analyses were constructed to identify the lipid biomarkers for nsCLP. The diagnostic model achieved high performance with 3 lipids in determining nsCLP. A panel of 3 lipid biomarkers showed great potential for nsCLP diagnosis. FA (20:4) and LPC (18:0) were also significantly downregulated in early serum samples from the nsCLP group in the additional validation cohort. We demonstrate the applicability and robustness of a machine-learning algorithm to analyze lipidomic data for efficient and reliable biomarker screening.

Growth Patterns Between Ages 0 and 36 Months Among US Children With Orofacial Cleft: A Retrospective Cohort Study

BACKGROUND

Little is known about how young children with orofacial cleft grow over time.

OBJECTIVE

To characterize longitudinal growth patterns from ages 0 to 36 months in US children with an orofacial cleft.

DESIGN

A retrospective cohort study.

PARTICIPANTS/SETTING

Children with cleft lip, cleft lip and palate, or cleft palate who were younger than age 36 months at a hospital encounter between 2010 and 2019 (N = 1334) were included. The setting was a US tertiary care children's hospital with a cleft center that serves a 5-state region.

MAIN OUTCOME MEASURE

Weight-for-age z scores (WAZ) and length-for-age z scores (LAZ).

STATISTICAL ANALYSES PERFORMED

Longitudinal growth patterns were characterized using generalized linear mixed models to estimate mean WAZ and LAZ from age 0 to 36 months.

RESULTS

Growth in infants with cleft slowed dramatically during the first 3 to 4 months of life, rebounded with catch-up growth until age 12 months for cleft lip and cleft palate and until age 36 months for cleft lip and palate. When comparing populations, children with any type of cleft demonstrated subpar growth compared with World Health Organization standards. Growth deficits were more common in those with cleft lip and palate and cleft palate compared with those with cleft lip. The intraclass coefficient showed that most of the variability in the WAZ (65%) was between individuals, whereas 35% was within an individual. The intraclass coefficient for LAZ showed that most of the variability in the LAZ (74%) was between individuals, whereas 26% was within an individual. The proportion of variance attributable to cleft type and/or comorbidities accounted for <5% of the variance for WAZ and LAZ. WAZ and LAZ were lower in children with comorbidities than those without comorbidities with cleft and World Health Organization standards.

CONCLUSIONS

Infants with cleft lip and palate, cleft palate, and a cleft with comorbidities have higher rates of poor growth than peers with cleft lip and a cleft with no comorbidities, respectively.

Evaluating Differences in Non-Syndromic Orofacial Clefts by Infant Sex: National Birth Defects Prevention Study, 1997 - 2011

OBJECTIVE

To investigate non-genetic factors that may contribute to observed differences in non-syndromic orofacial clefts by infant sex.

STUDY DESIGN

Using data for 1997-2011 deliveries from the National Birth Defects Prevention Study, a case-control study, we separately examined associations between 23 maternal factors and cleft lip with or without cleft palate (CL/P) and cleft palate alone (CP) using multivariable logistic regression stratified by infant sex.

RESULTS

We compared 2,986 infants with CL/P and 1,557 with CP to 11,271 control infants without birth defects. After adjusting for maternal age at conception and education, lower odds of non-syndromic orofacial clefts were observed among male infants of non-Hispanic Black mothers (CL/P aOR: 0.36; 95% CI: 0.28 - 0.45; CP aOR: 0.56; 95% CI: 0.41 - 0.76) and of Hispanic mothers (CL/P aOR: 0.84; 95% CI: 0.73 - 0.96; CP aOR: 0.57; 95% CI: 0.45 - 0.72) compared with non-Hispanic White mothers. Similar, though attenuated, lower odds of non-syndromic orofacial clefts were observed among female infants of non-Hispanic Black mothers, but no association was observed among female infants of Hispanic mothers. Differences in associations between maternal education and nutrient intake (carbohydrate, energy, total lipids/fat, Vitamin E, and zinc) and CL/P, as well as maternal vitamin C intake and CP, were also observed by infant sex.

CONCLUSIONS

Associations between non-syndromic orofacial clefts and minority racial and ethnic groups were attenuated or non-existent among female infants compared with male infants. Sex-specific differences of CL/P appear more susceptible to environmental factors (eg, maternal education and nutrient intake) than sex-specific differences of CP.

Burden of orofacial clefts from 1990-2021 at global, regional, and national levels

Objectives

We aimed to study and comprehensively evaluate the burden of OFCs at global, regional, and national levels.

Methods

Based on data from the Global Burden of Disease database for 2021, we analysed the prevalence, mortality, and disability-adjusted life years (DALYs) of orofacial clefts (OFCs) from 1990-2021, categorised by sex, regions, and sociodemographic index (SDI). Numbers and age-standardised rates (ASRs) of the aforementioned indices were estimated through a systematic analysis of modelled data from the GBD 2021 study. Finally, the relationship between SDI and the epidemiological parameters of OFCs was evaluated.

Results

In 2021, the global prevalence of OFCs included 4,124,007 cases, resulting in 1,719 deaths and 408,775 DALYs. From 1990-2021, prevalence cases decreased by 40.38%, while mortality rates, and DALYs decreased by 86.08%, and 68.33%, respectively. Moreover, the ASRs for prevalence, mortality, and DALYs demonstrated a decreasing trend during the period. In 2021, the highest age-standardised prevalence rates (ASPRs) of OFCs were recorded in South Asia, North Africa, the Middle East, and Central Asia. Nationally, Palestine, Qatar, and Bangladesh reported the three highest ASPRs in 2021. A nonlinear association was observed between the ASRs of OFCs and the SDI at regional and national levels.

Conclusions

The global burden of OFCs decreased from 1990-2021. However, there is a disparity in disease burden across different regions, over 80% of the burden is borne by patients in low- and middle-income countries, the burden of OFCs remains a major public health challenge globally. Our findings will help to formulate appropriate policies to reduce the OFCs burden.

An epidemiological investigation of oral and maxillofacial anomalies in newborns and their relation to parental health in the Ha'il Region, Saudi Arabia

This study aimed to determine the prevalence of oral and maxillofacial anomalies among newborns in the Ha'il Region, Saudi Arabia, and to explore associations with parental health, socioeconomic status, and environmental factors. Given the scarcity of regional data on congenital anomalies, this research furthers the understanding of localised health risks and could inform targeted interventions. A cross-sectional hospital-based study was conducted involving 40,000 newborns born between December 2019 and June 2024. Data were collected from medical records and parental interviews at one of the main hospitals in the Ha'il Region. Anomalies were categorised and analysed using the Statistical Package for Social Sciences software, with statistical significance set at p < 0.05. Forty-seven cases (0.146%) of oral and maxillofacial anomalies were identified, with a higher prevalence seen in female newborns. Relationship were found between these anomalies and parental smoking, socioeconomic status, and parental health history. Anomalies, such as cleft lips and palates, were more frequent in females, while other conditions, like the eruption of chlorodontia, were exclusive to males. This study underscores the importance of addressing environmental and socioeconomic factors to prevent congenital anomalies. These findings provide crucial data for healthcare planning in the Ha'il Region, aligning with Saudi's Vision 2030 objectives related to improving neonatal and maternal care.

Multidisciplinary Optimal Outcomes Reporting and Team Clinic Retention in Isolated Nonsyndromic Cleft Palate

ObjectiveOptimal Outcomes Reporting was recently introduced to categorize outcomes after cleft palate repair. We seek to propose an expanded version of Optimal Outcomes Reporting and to determine if correlation exists between the expanded outcomes and persistence with team care follow-up through age 9.DesignRetrospective cohort study.SettingCleft team at large pediatric hospital.PatientsPatients with isolated nonsyndromic cleft palate (n = 83) born from 2001-2012.Main Outcome MeasuresPatients who continued to present at age 5 or greater were assessed for optimal outcomes. Optimal outcomes were: surgery - no fistula or velopharyngeal insufficiency; otolaryngology - no obstructive sleep apnea or signs of chronic middle ear disease; audiology - no hearing loss; speech-language pathology - no assessed need for speech therapy.ResultsOf the 83 patients identified, 41 were assessed for optimal outcomes. Optimal outcome in any discipline was not associated with follow-up through age 9 (0.112 ≤ p ≤ 0.999). For all disciplines, the group with suboptimal outcomes had a higher proportion of patients from geographic areas in the most disadvantaged quartile of social vulnerability index, with the strongest association in the group with suboptimal speech outcome (OR 6.75, 95% CI 0.841-81.1).ConclusionsOptimal outcomes and retention in team clinic were not statistically significantly associated, but clinically relevant associations were found between patients in the most disadvantaged quartile of social vulnerability and their outcomes. A patient-centered approach, including caregiver education about long-term care for patients with cleft palate, would allow for enhanced resource utilization to improve retention for patients of concern.

Care Pathways for Undocumented Migrant Children Seeking Cleft Lip and Palate Care: Institutional Experience, Current State Policies, and Opportunities

Timely medical care is crucial for optimal outcomes in children with cleft lip and palate. Undocumented migrant children face significant healthcare barriers. This study assesses the demographic characteristics and unmet surgical needs of undocumented children at our institution and analyzes state-level policies affecting their care.

A retrospective review was conducted at a single institution between 2023 and 2024. Medicaid and Children's Health Insurance Program policies were reviewed as of August 2024, categorizing states by immigrant child healthcare coverage.

Multidisciplinary cleft clinic in a pediatric referral center.

Ten undocumented children were included, with clinical data and immigration status collected from social work and insurance records.

Timing of initial cleft surgery, additional surgical needs, and surgical completion were assessed.

Ten undocumented children were identified, with a mean age of 7 (range 1-10) years. Eight received primary cleft surgery in their home countries, but many had unmet surgical needs, including alveolar bone grafting (n = 4), oronasal fistula closure (n = 5), and dental care (n = 3). Twelve states provide comprehensive coverage regardless of immigration status, with 2 more expected by 2025. Twenty-three states cover only certain noncitizens without a waiting period, while 14 impose a 5-year delay. Broad coverage was concentrated in the Northeast and West (P = .002), with only one US-Mexico border state included.

This study highlights barriers undocumented migrant children face in accessing cleft care, with disparities in state-funded policies potentially delaying critical interventions. Addressing these disparities is essential for equitable healthcare access.

Pregnancy Termination Policy and Cleft Lip and Palate

BACKGROUND

Restrictive policies on termination of pregnancy (TOP) may lead to more infants with congenital abnormalities. This study aimed to assess the association between statewide enactment of TOP restriction and cleft lip and/or palate (CL/P) incidence, and to identify mediating demographic characteristics.

METHODS

The authors examined state-specific trends in CL/P incidence in infants before and after implementation of laws restricting TOP in Michigan compared with New York, where no such laws were passed. The percentage change of CL/P incidence per 1000 live births in postpolicy years (2012 to 2015) compared with prepolicy years (2005 to 2011) was compared, with adjustments for confounding factors in multivariate models.

RESULTS

The incidence of CL/P changed significantly in Michigan (19.1%) compared with New York (-7.31%). Adjusting for sex, race/ethnicity, median household income level, and expected payer, the adjusted percentage difference between Michigan and New York was 53.3% ( P < 0.001). Stratification by race/ethnicity and median household income demonstrated that changes were only significant among Black (139%; P < 0.001) and Hispanic (125%; P = 0.045) patients and among those from the lowest (50.3%; P < 0.001) and second lowest (40.1%; P = 0.01) income quartiles.

CONCLUSION

The authors' research, combined with the recent Supreme Court decision in Dobbs v Jackson Women's Health Organization allowing states to place further restrictions on TOP, suggests that more infants in the future will be born in need of treatment for CL/P.

Type of Cleft and Socioeconomic Determinants for Increased Caries Risk Among Young Patients With Cleft Lip and/or Palate

This study aimed to identify the predictive role of cleft type, ethnicity, adoption status, spoken language at home and parental education level on the caries risk in the primary dentition of patients with cleft lip and/or palate (CL/P). This knowledge is used to make an estimate on increased caries risk in young patients with CL/P.

A retrospective analysis of data concerning dental caries and basic characteristics of patients with CL/P was done. Patients were born and registered in 2016, 2017, or 2018 at the cleft team of the Erasmus Medical Center, Rotterdam, the Netherlands.

After Chi-square tests, the cleft type (P = .02), country of birth father (P < .001), country of birth mother (P = .002), parental educational level (P = .006), and spoken language at home (P = .002) were significantly different between 144 patients with CL/P with and without caries. Items were used in binary logistic regressions and after stepwise backward elimination resulting in most important determinants for caries in the primary dentition in patients with CL/P being: father born in another country than the Netherlands (odds ratio [OR] = 4.87, P = .001), a cleft lip alveolus and palate phenotype (OR = 3.54, P = .002), and a lower parental educational level (OR = 2.30, P = .04).

The recommendation for the dental care professional will be to use these 3 determinants as a first prediction on future dental caries. This helps the dental professional in clinical decisions as recall intervals, referral to specialized dental care and extensiveness of caries prevention strategies and thereby improves oral health of patients born with CL/P.

Social Determinants of Health in Early Otologic and Audiologic Evaluation in an Interdisciplinary Cleft-Craniofacial Clinic

OBJECTIVE

Investigate associations between socioeconomic indicators of healthcare access with family compliance with cleft-related otologic and audiologic care within an interdisciplinary model.

DESIGN

Retrospective case series.

SUBJECTS AND SETTING

Children born 2005-2015 who presented to the Cleft-Craniofacial Clinic (CCC) at a quaternary care children's hospital.

INTERVENTIONS

Associations between main outcome measures and Area Deprivation Index (ADI), median household income for zip code, distance from hospital, and insurance status were evaluated.

MAIN OUTCOME MEASURES

Cleft types, ages at presentation to outpatient clinic (cleft, otolaryngology, and audiology), and ages at procedures (first tympanostomy tube insertion (TTI), lip repair, and palatoplasty) were measured.

RESULTS

Most patients were male (147/230, 64%) with cleft lip and palate (157/230, 68%). Median age at first cleft, otolaryngology, and audiology visits were 7 days, 86 days, and 5.9 months, respectively. Private insurance predicted lower no-show rates (p = .04). Age at first CCC visit was younger for patients with private insurance (p = .04) and older for those who lived further from the hospital (p = .002). Age at lip repair was positively correlated with national ADI (p = .03). However, no socioeconomic status (SES) proxy or proximity to hospital was associated with delays in first otolaryngology or audiology examination or TTI.

CONCLUSION

Once children become established within an interdisciplinary CCC, SES appears to bear little influence on cleft-related otologic and audiologic care. Future efforts should aim to elucidate which aspects of the interdisciplinary model maximize multisystem cleft care coordination and increase access for higher risk populations.

Demystifying Velopharyngeal Dysfunction for Plastic Surgery Trainees-Part 1: Anatomy and Physiology

The velopharyngeal (VP) port separates the nasopharynx from the oropharynx and is bordered by the velum, lateral pharyngeal walls, and posterior pharyngeal wall. Velopharyngeal dysfunction (VPD) is the inability to achieve proper closure of the VP port, affecting speech and swallowing. This 3-part series provides a comprehensive discussion on (1) the anatomy and physiology of the velopharyngeal mechanism; (2) fundamental speech terminology and principles of perceptual speech assessment for VPD; and (3) techniques for objective evaluation of the VP port and surgical decision-making process. In part 1, the authors focus on the anatomy and physiology of the velopharyngeal port, the anatomy of cleft palate, and the causes of VPD. There are 3 types of VPD: velopharyngeal insufficiency, involving structural deficits; velopharyngeal incompetence, resulting from neuromuscular issues; and velopharyngeal mislearning, due to maladaptive speech habits. VPD is commonly associated with cleft palate due to anatomic disruptions that impair velopharyngeal function. However, there are numerous causes of noncleft VPD, including congenital or acquired structural defects, neuromuscular conditions, and developmental/behavioral factors. Diagnosis and management of VPD require a multidisciplinary approach involving, at a minimum, surgeons and speech-language pathologists. Plastic surgery trainees often receive education on the surgical treatment of VPD, but without a foundational knowledge of the disease spectrum and speech pathology, the complex terminology can impede a thorough understanding of its diagnosis and management. This series serves as an accessible resource, providing the foundational knowledge required for surgical trainees new to this topic.

Characterizing Interventions and Family Assistance of a Nurse Navigation Program in Orofacial Cleft Care

OBJECTIVE

Characterize the interventions and assistance employed by a cleft nurse navigator (CNN) which have mediated improvement in care equity at our institution.

DESIGN

Retrospective study.

SETTING

Academic tertiary care center.

PATIENTS, PARTICIPANTS

Patients presenting with cleft lip and/or cleft palate presenting between August 2020 and August 2021 with exclusions for syndromic diagnosis, Pierre-Robin sequence, late (> 6 months) presentation, and prior cleft surgery at outside institutions.

INTERVENTIONS

Multidisciplinary cleft nurse navigator program.

MAIN OUTCOME MEASURE(S)

Family interactions with the CNN by phone, text, and email across the first year of life including feeding support, nasoalveolar molding (NAM) assistance, appointment scheduling, financial assistance, addressing perioperative concerns, and facilitating physician consults. Patient weight and surgical timing were also recorded.

RESULTS

Sixty-nine patients were included with a total of 639 interactions between the CNN and families. Scheduling support (30%), addressing perioperative concerns (22%), and feeding support (20%) were the most common interactions. Feeding support and NAM assistance were heavily distributed in the first 3 months of life compared to after 3 months (P < .001). Median age at first contact was 1 week (range: 22 weeks gestation-14 weeks). There was no difference in the proportion of families receiving feeding support, NAM assistance, or scheduling assistance based on insurance status or race (P > .05 for all).

CONCLUSIONS

Scheduling assistance, addressing perioperative concerns, and feeding support are the predominant methods by which the CNN interacts with and assists families of patients with cleft conditions. CNN service distribution is largely equitable between demographic groups.

A Geospatial Analysis of Barriers to Cleft Lip and Palate Care in the United States

OBJECTIVE

This study evaluates the geospatial distribution of cleft lip and/or cleft palate (CL/P) care in the United States, assesses disparities between families with and without one-hour proximity to CL/P care, and recommends interventions for improving access.

DESIGN

We identified American Cleft Palate Craniofacial Association-approved CL/P teams and calculated a one-hour driving radius around each clinic. We then used census data to compare risk factors for developing cleft (i.e., incidence risk factors) and obstacles to care (i.e., access risk factors) between counties with and without one-hour proximity.

RESULTS

We identified 187 CL/P teams in 45 states. Most were in the South (n = 60, 32.0%), though children in the Middle Atlantic had the greatest access to care. Alabama, Mississippi, Tennessee, and Kentucky had the least access. Children without access were 39% more likely to have gestational tobacco exposure, 8% more likely to have gestational obesity exposure, and 28% less likely to have health insurance (p < 0.01). Children without access in the South were 29% more likely to have a low birth weight and 46% more likely to be living below the poverty line (p < 0.01). Children with access were twice as likely to live in immigrant families and 7-times more likely to speak English as a second language.

CONCLUSIONS

Pronounced disparities affect patients with and without one-hour access to CL/P care. Interventions should address care costs for patients living furthest without access and language barriers for patients with access that speak English as a second language.

Epidemiologic Trends of Cleft Lip and Palate in a Southern State: A 30-Year Follow-Up

OBJECTIVES

Children's of Mississippi at the University of Mississippi Medical Center serves as the state's only American Cleft Palate-Craniofacial Association-approved cleft team at the only pediatric hospital in the state. The goal of this study is to report geographic and demographic patterns of patients with orofacial cleft (OFC) treated at Children's of Mississippi, which are lacking.

METHODS

Patients with OFC treated at Children's of Mississippi from 2015 to 2020 were included. Demographic data were collected, including birth county and total live births from state data. Significant differences between incidence of OFC among public health regions of Mississippi were examined using analysis of variance (P < 0.05). Cases were compared with historical data from 1980 to 1989.

RESULTS

There were 184 patients who presented with OFC, with a statewide incidence of 0.83 per 1000 live births among 222,819 live births in the state across 6 years. The incidence of OFC was 0.83/1000 for Whites and 0.82/1000 for non-Whites versus a historical rate of 1.36 and 0.54, respectively. Significantly fewer children in the northern region (0.25/1000) were born with OFC than in central (1.21; P < 0.001) and southern (0.86; P < 0.001) regions.

CONCLUSIONS

Results from this study suggest changing regional patterns of OFC in Mississippi. Although rates increased among non-White infants, the overall incidence of OFC has decreased compared with historical data. The findings may reflect actual incidence patterns in the state or the proximity of certain regions to Children's of Mississippi. Further study may reveal regional differences in risk factors underlying OFC incidence, and/or issues with access to cleft care for different regions in the state.

Impact of Prenatal Care on Newborn Complications for Infants with Cleft Lip with or Without Cleft Palate

OBJECTIVE

To determine the association between prenatal care and cleft lip with or without cleft palate (CL ± P) and examine differences in newborn complications among infants diagnosed with CL ± P as a function of prenatal care.

DESIGN

Population-based retrospective cohort study.

SETTING

2018 United States National Vital Statistics System-Natality component (NVSS-N) was used to examine nationwide birth certificate data.

PARTICIPANTS

3,414,338 infants from the 2018 National Vital Statistics System, of which 1,699 had CL ± P.

MAIN OUTCOME MEASURE

Diagnosis of CL ± P and presence of newborn complications as a function of prenatal care.

RESULTS

Significant differences were found among various infant- and mother-specific variables when baseline comparisons were made between infants with and without CL ± P. After controlling for baseline differences, results indicated decreased odds of a diagnosis of CL ± P in cases where overall adequate prenatal care was obtained (OR = .841; 95% CI .757, .934), including prenatal care beginning in the 1st trimester (OR = .839; 95% CI .750, .939) and an adequate number of prenatal visits received (OR = .864; 95% CI .764, .976). Of infants with CL ± P, reduced odds of the infant admitted to the neonatal intensive care unit (OR = .777; 95% CI .613, .985) or transferred (OR = .601; 95% CI .407, .888) were apparent when adequate prenatal care was received.

CONCLUSION

Results suggest adequate prenatal care not only reduces the likelihood of CL ± P in infants but may also decrease the severity of negative outcomes in infants diagnosed with CL ± P. These findings emphasize necessity for adequate prenatal care.

Maternal factors in the origin of cleft lip/cleft palate: A population-based case-control study

OBJECTIVES

Orofacial clefts are among the most common birth defects, with an estimated worldwide incidence of around 1.5-1.7 per 1000 live-born babies. The most frequent form of orofacial clefts is cleft lip with or without cleft palate (CL ± CP). The role of environmental factors in the development of clefts is unclear in most patients, thus the aim of this study was to estimate possible maternal risk factors in the origin of CL ± CP.

MATERIALS AND METHODS

1648 CL ± CP cases, 2654 matched controls and 57 231 population controls were evaluated from The Hungarian Case-Control Surveillance of Congenital Abnormalities. Maternal factors during the critical period in cases and controls were compared. Adjusted odds ratios (OR) with 95% confidence intervals (CI) were estimated in a multivariable conditional logistic regression model.

RESULTS

Among socio-demographic data, we have found significant differences between maternal employment. The proportion of unskilled mothers (6.5%) were higher in the CL ± CP group than in controls (3.5%). Medically recorded maternal anaemia, excessive vomiting and threatened abortion were associated with a higher risk of CL ± CP. An elevated risk was also found in various acute illnesses such as influenza (OR: 2.4, 95% CI: 3.0-5.8), acute bronchitis (OR: 4.5, 95% CI: 1.6-12.6) and urinary tract infections (OR: 3.5, 95% CI: 2.0-6.0). Maternal migraine and essential hypertension occurred more frequently in the mothers of cases than in controls.

CONCLUSION

The findings of this study suggest that maternal diseases and lifestyle factors during the first trimester play a significant role in the development of CL ± CP.

Incomes to Outcomes: A Global Assessment of Disparities in Cleft and Craniofacial Treatment

OBJECTIVE

Recent investigations focused on health equity have enumerated widespread disparities in cleft and craniofacial care. This review introduces a structured framework to aggregate findings and direct future research.

DESIGN

Systematic review was performed to identify studies assessing health disparities based on race/ethnicity, payor type, income, geography, and education in cleft and craniofacial surgery in high-income countries (HICs) and low/middle-income countries (LMICs). Case reports and systematic reviews were excluded. Meta-analysis was conducted using fixed-effect models for disparities described in three or more studies.

SETTING

N/A.

PATIENTS

Patients with cleft lip/palate, craniosynostosis, craniofacial syndromes, and craniofacial trauma.

INTERVENTIONS

N/A.

RESULTS

One hundred forty-seven articles were included (80% cleft, 20% craniofacial; 48% HIC-based). Studies in HICs predominantly described disparities (77%,) and in LMICs focused on reducing disparities (42%). Level II-IV evidence replicated delays in cleft repair, alveolar bone grafting, and cranial vault remodeling for non-White and publicly insured patients in HICs (Grades A-B). Grade B-D evidence from LMICs suggested efficacy of community-based speech therapy and remote patient navigation programs. Meta-analysis demonstrated that Black patients underwent craniosynostosis surgery 2.8 months later than White patients (P < .001) and were less likely to undergo minimally-invasive surgery (OR 0.36, P = .002).

CONCLUSIONS

Delays in cleft and craniofacial surgical treatment are consistently identified with high-level evidence among non-White and publicly-insured families in HICs. Multiple tactics to facilitate patient access and adapt multi-disciplinary case in austere settings are reported from LMICs. Future efforts including those sharing tactics among HICs and LMICs hold promise to help mitigate barriers to care.

Evidence-Based Practices in Cleft Palate Surgery

LEARNING OBJECTIVES

After studying this article, the participant should be able to: (1) Understand the embryologic origins, cause, and incidence of cleft palate. (2) Review the anatomy and common classifications of cleft palate and associated defects. (3) Describe surgical techniques for palatoplasty and understand their respective indications. (4) Gain an awareness of general perioperative care considerations, timing of repair, and risk factors for and operative mitigation of complications.

SUMMARY

Cleft palate affects 0.1 to 1.1 per 1000 births, with a higher incidence in certain ethnic groups but affecting both sexes equally. Cleft palate may occur in isolation or in combination with cleft lip or in association with other congenital anomalies including various syndromes. The goals of cleft palate repair are to anatomically separate the oral and nasal cavities for normal feeding and improved speech and minimize the risk of oronasal fistulas, velopharyngeal dysfunction, and disruption of facial growth. This review discusses the incidence, causes, and classification of cleft palate; surgical techniques for palatoplasty and perioperative patient management; and complications of palatoplasty.

Impact of Neighborhood Deprivation and Social Vulnerability on Outcomes and Interventions in Patients with Cleft Palate

OBJECTIVE

To examine whether neighborhood disadvantage impacts length of follow-up, interventions, and outcomes for patients with cleft palate.

DESIGN

Retrospective cohort.

SETTING

Cleft Palate Craniofacial Institute Database at St. Louis Children's Hospital.

PATIENTS/PARTICIPANTS

Patients with cleft palate following in St. Louis Children's Hospital Cleft Palate Multidisciplinary Team Clinic.

INTERVENTIONS

Primary palatoplasty between 2012-2017. Patients were divided into quartiles across area deprivation index (ADI) and social vulnerability index (SVI), two validated, composite metrics of neighborhood disadvantage, to examine whether living in neighborhoods from different deprivation quartiles impacts outcomes of interest.

MAIN OUTCOME MEASURE

Follow-up through age 5, surgeries and surgical complications, speech, developmental, and behavioral outcomes.

RESULTS

205 patients were included. 39% of patients belonged to the most deprived ADI quartile, while 15% belonged to the most vulnerable SVI quartile. There were no differences between ADI or SVI quartiles in number of operations received (p ≥ 0.40). Patients in the most deprived ADI quartile were significantly more likely to have speech/language concerns (OR 2.32, 95% CI [1.20-4.89], p = 0.01). Being in a more vulnerable SVI quartile was associated with developmental delay (OR 2.29, 95% CI [1.04-5.15], p = 0.04). ADI and SVI quartile did not impact risk of loss to follow-up in the isolated and combined cleft lip and palate subgroups (p ≥ 0.21).

CONCLUSIONS

Neighborhood disadvantage impacts speech and developmental outcomes in patients with cleft palate despite comparable length of follow-up in multidisciplinary team clinic.

US air pollution is associated with increased incidence of non-syndromic cleft lip/palate

Maternal cigarette use is associated with the fetal development of orofacial clefts. Air pollution should be investigated for similar causation. We hypothesize that the incidence of non-syndromic cleft lip with or without palate (NSCLP) and non-syndromic cleft palate (NSCP) would be positively correlated with air pollution concentration.

METHODS

The incidence of NSCLP and NSCP per 1000 live births from 2016 to 2020 was extracted from the Centers for Disease Control and Prevention Vital Statistics Database and merged with national reports on air pollution using the Environmental Protection Agency Air Quality Systems annual data. The most commonly reported pollutants were analyzed including benzene, sulfur dioxide (SO2), particulate matter (PM) 2.5, PM 10, ozone (O3), and carbon monoxide (CO). Multivariable negative binomial and Poisson log-linear regression models evaluated the incidence of NSCLP and NSCP as a function of the pollutants, adjusting for race. All p-values are reported with Bonferroni correction.

RESULTS

The median NSCLP incidence was 0.22/1000 births, and isolated NSCP incidence was 0.18/1000 births. For NSCLP, SO2 had a coefficient estimate (CE) of 0.60 (95% CI [0.23, 0.98], p < 0.007) and PM 2.5 had a CE of 0.20 (95% CI [0.10, 0.31], p < 0.005). Among isolated NSCP, no pollutants were found to be significantly associated.

CONCLUSION

SO2 and PM 2.5 were significantly correlated with increased incidence of NSCLP. The American people and perinatal practitioners should be aware of the connection to allow for risk reduction and in utero screening.

Association between gestational exposure and risk of orofacial clefts: a systematic review and meta-analysis

BACKGROUND

The occurrence of orofacial Clefts (OFCs) is a congenital disease caused by many factors. According to recent studies, air pollution has a strong correlation with the occurrence of OFCs. However, there are still some controversies about the current research results, and there is no relevant research to review the latest results in recent years.

OBJECTIVE

In this paper, the authors conducted a systematic review and meta-analysis to explore the correlation between ambient air pollution and the occurrence of neonatal OFCs deformity.

METHODS

We searched Pubmed, Web of science, and Embase databases from the establishment of the database to May 2023. We included observational studies on the relationship between prenatal exposure to fine particulate matter 2.5 (PM2.5), fine particulate matter 10 (PM10), sulfur dioxide (SO2), nitrogen dioxide (NO2), ozone (O3), carbon monoxide (CO) and the risk of cleft lip (CL), cleft palate (CP), cleft lip with or without palate (CL/P). the Newcastle-Ottawa quality assessment scale (NOS) was used to evaluate the quality of the literature. Funnel plot and Egger's regression were used to verify the publication bias. Random effect model or fixed effect model was used to estimate the combined relative risk (RR) and 95% confidence interval (95%CI).

RESULTS

A total of eleven studies were included in this study, including four cohort studies and seven case-control studies, including 22,453 cases of OFCs. Ten studies had low risk of bias and only one study had high risk of bias. Three studies reported that PM2.5 was positively correlated with CL and CP, with a combined RR and 95%CI of 1.287(1.174,1.411) and 1.267 (1.105,1.454). Two studies reported a positive correlation between O3 and CL, with a combined RR and 95%CI of 1.132(1.047,1.225). Two studies reported a positive correlation between PM10 and CL, with a combined RR and 95%CI of 1.108 (1.017,1.206). No association was found between SO2, CO, NO2 exposure during pregnancy and the risk of OFCs.

CONCLUSION

The results of this study showed that there was a significant statistical correlation between exposure to PM10, PM2.5, O3 and the risk of OFCs in the second month of pregnancy. Exposure assessment, research methods and mechanisms need to be further explored.

Hybrid Bionic Nerve Interface for Application in Bionic Limbs

Intuitive and perceptual neuroprosthetic systems require a high degree of neural control and a variety of sensory feedback, but reliable neural interfaces for long-term use that maintain their functionality are limited. Here, a novel hybrid bionic interface is presented, fabricated by integrating a biological interface (regenerative peripheral nerve interface (RPNI)) and a peripheral neural interface to enhance the neural interface performance between a nerve and bionic limbs. This interface utilizes a shape memory polymer buckle that can be easily implanted on a severed nerve and make contact with both the nerve and the muscle graft after RPNI formation. It is demonstrated that this interface can simultaneously record different signal information via the RPNI and the nerve, as well as stimulate them separately, inducing different responses. Furthermore, it is shown that this interface can record naturally evoked signals from a walking rabbit and use them to control a robotic leg. The long-term functionality and biocompatibility of this interface in rabbits are evaluated for up to 29 weeks, confirming its promising potential for enhancing prosthetic control.

Limited Access to Alveolar Bone Graft Surgery Following Primary Cleft Lip and Palate Repair in Indonesia: A Questionnaire-Based Qualitative Study

INTRODUCTION

Cleft Lip and Palate is the most common craniofacial anomaly, and cleft lip and palate repair is widely performed. Alveolar cleft accompanies 75% of cleft lip cases and requires alveolar bone graft (ABG) surgery at mixed dentition age. However, studies on rates of ABG surgery are scarce.

OBJECTIVE

This study aims to investigate the low popularity of ABG and orthodontic care among patients with ABG history at Cleft and Craniofacial Centre, Cipto Mangunkusumo Hospital, Jakarta.

METHOD

A total of 771 patients had orofacial cleft surgeries throughout 2015 to 2021. A descriptive analysis of labioplasty, palatoplasty, and ABG surgeries was presented. Questionnaire-based qualitative analysis of ABG was obtained from the patient's guardians to evaluate the limitation and experience of conducting the surgery at our institution.

RESULTS

We distributed questionnaires to 13 patients with a history of ABG. ABG accounted for only 5% of total orofacial cleft surgeries. The average age of ABG surgery and orthodontic care initiation was 11 and 11.8 years old, respectively. About 82% had access to preoperative and postoperative orthodontic care; however, only 11% received PSO before 9 years old. The satisfaction rate was 100% and 75% in ABG patients with and without orthodontic care, respectively, reporting improved feeding, speech, teeth alignment, and esthetic result.

CONCLUSION

Orofacial cleft management requires a multistage, comprehensive, and multidisciplinary approach. The number of ABG surgeries is low in developing countries, attributed to unequal access to ABG and orthodontic care, suggesting that limitations of knowledge, geography, and economy play a big role in Indonesian healthcare.

A Cross-Sectional Study of the Nutritional Status of Infants with Orofacial Clefts in the First 6 Months of Life

OBJECTIVE(S)

To estimate nutritional status in a large cohort of infants with orofacial clefts in the US, overall and by cleft type from birth to 6 months of age.

STUDY DESIGN

We conducted a cross-sectional study in infants with orofacial clefts by examining growth by month between birth and 6 months of age. Infants with at least one weight measurement at a single US regional tertiary care pediatric hospital with an interdisciplinary cleft team between 2010 and 2020 were included. We calculated the average weight-for-age z scores and weight-for-length z scores. We calculated the proportion of infants underweight and wasting with z scores below -2 SDs monthly from birth to 6 months of age. We used t tests to compare the distribution of weight for age z-score and weight for length z-score among children with orofacial clefts to a normal distribution.

RESULTS

We included 883 infants with orofacial clefts. Compared with expected proportion of underweight infants (2.3%), a larger proportion of infants with orofacial clefts were underweight between birth and 1 month (10.6%), peaking between 2 and 3 months (27.1%), and remaining high between 5 and 6 months (16.3%). Compared with the expected proportion of infants with wasting (2.3%), a higher proportion of infants with orofacial clefts experienced wasting between birth and 1 month (7.3%), peaking between 2 and 3 months (12.8%), and remaining high between 5 and 6 months (5.3%). Similar findings were observed for all cleft types and regardless of comorbidities.

CONCLUSION(S)

A substantial proportion of infants with orofacial clefts compared with normative peers have malnutrition in the first 6 months of life in the US.

Relationship between achieving Sustainable Development Goals and promoting optimal care and prevention of birth defects globally

Birth defects affect eight million newborns annually worldwide. About 8% of global under-5 mortality is attributable to birth defects. The United Nations (UN) Sustainable Development Goals (SDGs) have set 17 global goals for human growth and development to be achieved by 2030 using multi-sectorial approaches. The third goal (SDG-3) focuses on ensuring healthy lives and promoting well-being; achieving SDG-3 improves birth defects care and prevention. However, we aimed to show how achieving other SDGs also influence optimal care and prevention of birth defects. SDGs focused on poverty reduction, access to nutritious food, universal health coverage, equitable education, gender equality, environment, inclusivity through infrastructure innovation, and strengthening social justice is crucial to addressing social determinants of health for individuals and families affected by birth defects. Understanding birth defects in the context of several relevant SDGs will allow practitioners, researchers, and policymakers to leverage the momentum generated by SDGs and make a case for commitment and allocation of funding and resources for advancing birth defects surveillance, care, and prevention. SDGs are built on principles of equity and social justice and we urge policy-makers to approach birth defects using various SDGs as a catalyst. The synergy between several SDGs helps to optimize birth defect outcomes and prevention. Our effort to present a more comprehensive look at various SDGs and their relationship with birth defects is parallel to several other health advocacy groups conducting a similar mapping exercise, thus bringing to the forefront millions of lives that are impacted by birth defects worldwide.

Inter-centre comparison of data on surgery and speech outcomes at 5 years of age based on the Swedish quality registry for patients born with cleft palate with or without cleft lip

BACKGROUND

The objective of the Swedish cleft lip and palate registry (CLP registry) is to promote quality control, research and improvement of treatment, by the comparison of long-term results. The aim was to compare data from the CLP registry among the six treatment centres, regarding data on surgery and speech outcomes at 5 years of age.

METHODS

The participants were 430 children born in Sweden from 2009 to 2014, with cleft palate with or without cleft lip and without known syndromes and/or additional malformations. The number of primary and secondary palatal surgeries up to 5 years of age, timing of the last primary palatal surgery, percentage consonants correct, percentage non-oral speech errors and perceived velopharyngeal competence at 5 years were assessed. Multivariable binary logistic regression adjusted for sex and cleft type was used to compare results between the six centres.

RESULTS

At one centre (centre 4), the palate was closed in one to three stages, and at the remaining centres in one or two stages. At centre 4, more children underwent a higher number of palatal surgeries, and the last primary palatal surgery was performed at a higher age. Children in centre 4 were also less likely to achieve ≥86% correct consonants (OR = 0.169, P = < 0.001), have no non-oral speech errors (OR = 0.347, P = < 0.001), or have competent or marginally incompetent velopharyngeal competence (OR = 0.244, P = < 0.001), compared to the average results of the other centres. No clear association between patient volume and speech outcome was observed.

CONCLUSIONS

The results indicated the risk of a negative speech result if the last primary palatal surgery was performed after 25 months of age. Whether the cleft in the palate was closed in one or two stages did not affect speech outcome. The Swedish CLP registry can be used for open comparisons of treatment results to provide the basis for improvements of treatment methods. If deviating negative results are seen consistently at one centre, this information should be acted upon by further investigation and analysis, making changes to the treatment protocol as needed.
