Self-concept and academic achievement in children with chronic kidney disease

BACKGROUND

Within the pediatric population, a positive self-concept is associated with better academic achievement. Children with chronic kidney disease (CKD) are at risk for lower quality of life and academic underachievement. Little is known about self-concept among children with CKD and how self-concept influences academic achievement. The objectives of the present study were to (1) describe patient-reported self-concept among children with CKD and (2) evaluate the relationship between self-concept and academic performance.

METHODS

This cross-sectional study included 23 children, aged 6-16 years, with mild to moderate CKD (cause of disease due to congenital anomalies of the kidney and urinary tract) and 26 age-matched comparators. Participants completed the Self-Description Questionnaire (SDQ) and the Wide Range Achievement Test (WRAT-4). Linear regression models were used to evaluate self-concept as a predictor of academic achievement in the CKD cohort.

RESULTS

Self-concept ratings were comparable between children with CKD and non-CKD comparators; however, academic achievement trended lower for the CKD patients on measures of arithmetic (estimate =  - 0.278, 95% confidence interval (CI) [- 0.530: - 0.026], t(45) =  - 1.99, p = 0.053). All of the SDQ domains predicted WRAT-4 arithmetic performance, such that higher scores on the SDQ were associated with higher scores in mathematics. Kidney function did not have an effect on the relationship between self-concept and academic achievement.

CONCLUSIONS

Despite the presence of a chronic disease, children with CKD endorse a positive self-concept. Positive self-concept may predict academic success in this population.

Screening for Academic Risk Among Students With Cleft Lip and/or Palate: Patterns of Risk and Qualities of Effective Tools

This study evaluated the effectiveness of academic screening measures in relation to parent-reported diagnoses.

Multicenter, retrospective cohort study including structured interviews, questionnaires, and chart reviews.

Six North American cleft centers.

Children (n = 391) with cleft lip and/or palate, ages 8 to 10 years of age (192 male) and their guardians were recruited during regular clinic visits.

Parent and child ratings on the Pediatric Quality of Life Inventory (PedsQL) School Scale, child report on CleftQ School Scale, parent report on the Adaptive Behavior Assessment System-Third Edition Functional Academics (ABAS-FA) Scale and Child Behavior Checklist (CBCL) School Competency Scale, parent interview, and medical chart review.

Risk for concerns ranged from 12% to 41%, with higher risk reflected on the CBCL-SC compared to other measures. Males with cleft palate were consistently at the highest risk. Only 9% of the sample had a parent-reported diagnosis of a learning or language disability. Ratings from the ABAS-FA and CBCL-SC had the highest utility in identifying those with language and/or learning concerns.

As cleft teams work to develop standardized batteries for screening and monitoring of patients, it is important to evaluate the effectiveness of measures in identifying those at highest risk. When screening for language and learning disorders, questions related to potential academic struggles, such as increased school effort or increased school distress, are most useful. Referrals for follow-up evaluation are recommended for those identified at high risk.

A Multisite Study Investigating Child and Parent Proxy Reported Quality of Life in Children With Cleft Lip and/or Palate

This observational, multisite cohort study explored health-related quality of life (HRQoL) in children with cleft lip and/or palate (CL/P), including interrater agreement and ratings for this group relative to clinical cutoff scores and published means for healthy and chronically ill children.

Participants (338 children ages 8-10 years, 45.9% male and their parents, 82.0% female) across 6 sites completed the Pediatric Quality of Life Inventory Generic Core Scales (PedsQL).

Intraclass correlation revealed poor interrater agreement for most HRQoL domains. Although ratings were generally higher than those expected for children with a chronic illness, child ratings were below healthy means for school functioning, and parent proxy ratings were below healthy means for all domains except physical functioning. Lower ratings consistent with chronic illness means were found for self-reported emotional and psychosocial functioning in children with cleft lip and palate (CLP), as well as parent proxy-reported emotional, school, and psychosocial functioning for children with cleft palate (CP). Scores were most likely to be in the clinical range for children with CP for social, school, and total functioning.

Although parent proxy report provides important information about observed functioning, poor interrater agreement indicates that both child and parent proxy reported HRQoL should be included in outcomes assessment for CL/P. HRQoL ratings may be higher for children with CL/P compared to youth with other chronic illnesses, but psychosocial functioning may be negatively impacted when compared with healthy youth, particularly for emotional, social, and school functioning in children with CLP or CP.

Psychosocial Outcomes in Children with Cleft Lip and/or Palate: Associations of Demographic, Cleft Morphologic, and Treatment-Related Variables

OBJECTIVE

To determine associations of demographic, morphologic, and treatment protocol parameters with quality of life (QoL), appearance/speech satisfaction, and psychological adjustment.

DESIGN

Observational study utilizing retrospective report of protocol variables and current outcome variables.

SETTING

Six North American cleft treatment clinics.

PARTICIPANTS

Children, ages 8.0-10.99 years, with Cleft Lip ± Alveolus, Cleft Palate, Cleft Lip and Palate, and parents (N = 284).

OUTCOME MEASURES

Pediatric QoL Inventory (PedsQL): Parent, Child, Family Impact Module (FIM); Patient Reported Outcome Measurement Information System (PROMIS); Child Behavior Checklist (CBCL); CLEFT-Q.

RESULTS

Outcome scores were average with few differences by cleft type. Multiple regression analyses yielded significant associations (Ps < .05) between socioeconomic status, race, and age at assessment and parent- and self-reported measures. Females had higher PROMIS Depression (β=.20) but lower CBCL Affective (β = -.16) and PROMIS Stigma scores (β= -.24). Incomplete cleft lip was associated with lower PROMIS Depression, and more positive ratings of CLEFT-Q: Nose, Nostril, Lip Scar; CBCL Competence scores, (βs = -.17 to .17). Younger Age at Lip Closure was associated with higher CBCL School Competence (β= -.18). Younger Age at Palate Closure was associated with higher Child PedsQL Total, Physical, Psychosocial QoL, and better CLEFT-Q Speech Function (βs = -.18 to -.15). Furlow Palatoplasty was associated with more CBCL Externalizing Problems (β = .17) higher CBCL Activities (β = .16). For all diagnoses, fewer Total Cleft-Related Surgeries was associated with lower PROMIS Stigma and higher CBCL Total Competence and Activities (βs = -.16 to .15).

CONCLUSIONS

Demographic characteristics, lip morphology, and treatment variables are related to later psychological functioning.

Neurocognitive deficits may not resolve following pediatric kidney transplantation

BACKGROUND

Pediatric chronic kidney disease (CKD) patients are at risk for cognitive deficits with worsening disease progression. Limited, existing cross-sectional studies suggest that cognitive deficits may improve following kidney transplantation. We sought to assess cognitive performance in relationship to kidney transplantation and kidney-specific medical variables in a sample of pediatric kidney transplant patients who provided cross-sectional and longitudinal observations.

METHODS

A retrospective chart review was conducted in patients who completed pre- and/or post-transplant neurocognitive testing at the University of Iowa from 2015-2021. Cognitive outcomes were investigated with developmentally appropriate, standardized measures. Mixed linear models estimated the impact of transplant status on cognitive function (z-scores). Subsequent post-hoc t-tests on change scores were limited to patients who had provided pre- and post-transplant assessments.

RESULTS

Thirty eight patients underwent cognitive assessments: 10 had both pre- and post-transplant cognitive assessments, 11 had pre-transplant assessments only, and 17 had post-transplant data only. Post-transplant status was associated with significantly lower full-scale IQ and slower processing speed compared to pre-transplant status (estimate = -0.32, 95% confidence interval [CI] = -0.52: -0.12; estimate = -0.86, CI = -1.17: -0.55, respectively). Post-hoc analyses confirmed results from the mixed models (FSIQ change score = -0.34, 95% CI = -0.56: -0.12; processing speed change score = -0.98, CI = -1.28: -0.68). Finally, being ≥80 months old at transplant was associated with substantially lower FSIQ compared to being <80 months (estimate = -1.25, 95% CI = -1.94: -0.56).

CONCLUSIONS

Our results highlight the importance of monitoring cognitive function following pediatric kidney transplant and identify older transplant age as a risk factor for cognitive deficits.

Using fNIRS to evaluate ADHD medication effects on neuronal activity: A systematic literature review

Background

Functional near infrared spectroscopy (fNIRS) is a relatively non-invasive and inexpensive functional neuroimaging technique that has shown promise as a method for understanding the differences in neuronal activity associated with various neurodevelopmental conditions, including ADHD. Additionally, fNIRS has been suggested as a possible tool to understand the impact of psychotropic medications on brain activity in individuals with ADHD, but this approach is still in its infancy.

Objective

The purpose of this systematic literature review was to synthesize the extant research literature on the use of fNIRS to assess the effects of ADHD medications on brain activity in children and adolescents with ADHD.

Methods

A literature search following Preferred Reporting Items for Systematic Literature Reviews and Meta-Analyses (PRISMA) guidelines was conducted for peer-reviewed articles related to ADHD, medication, and fNIRS in PsychInfo, Scopus, and PubMed electronic databases.

Results

The search yielded 23 published studies meeting inclusion criteria. There was a high degree of heterogeneity in terms of the research methodology and procedures, which is explained in part by the distinct goals and approaches of the studies reviewed. However, there was also relative consistency in outcomes among a select group of studies that demonstrated a similar research focus.

Conclusion

Although fNIRS has great potential to further our understanding of the effects of ADHD medications on the neuronal activity of children and adolescents with ADHD, the current research base is still relatively small and there are limitations and methodological inconsistencies that should be addressed in future studies.

Behavioral features in child and adolescent huntingtin gene-mutation carriers

INTRODUCTION

We compared neuropsychiatric symptoms between child and adolescent huntingtin gene-mutation carriers and noncarriers. Given previous evidence of atypical striatal development in carriers, we also assessed the relationship between neuropsychiatric traits and striatal development.

METHODS

Participants between 6 and 18 years old were recruited from families affected by Huntington's disease and tested for the huntingtin gene expansion. Neuropsychiatric traits were assessed using the Pediatric Behavior Scale and the Behavior Rating Inventory of Executive Function. Striatal volumes were extracted from 3T neuro-anatomical images. Multivariable linear regression models were conducted to evaluate the impact of group (i.e., gene nonexpanded [GNE] or gene expanded [GE]), age, and trajectory of striatal growth on neuropsychiatric symptoms.

RESULTS

There were no group differences in any behavioral measure with the exception of depression/anxiety score, which was higher in the GNE group compared to the GE group (estimate = 4.58, t(129) = 2.52, FDR = 0.051). The growth trajectory of striatal volume predicted depression scores (estimate = 0.429, 95% CI 0.15:0.71, p = .0029), where a negative slope of striatal volume over time was associated with lower depression/anxiety.

CONCLUSIONS

The current findings show that GE children may have lower depression/anxiety compared to their peers. Previously, we observed a unique pattern of early striatal hypertrophy and continued decrement in volume over time among GE children and adolescents. In contrast, GNE individuals largely show striatal volume growth. These findings suggest that the lower scores of depression and anxiety seen in GE children and adolescents may be associated with differential growth of the striatum.

A preliminary examination of expressive writing in boys with isolated orofacial clefts

BACKGROUND

Children with isolated cleft of the lip and/or palate (iCL/P) are at a higher risk for language and reading issues. The current pilot study evaluated concurrent writing skills of children with iCL/P compared to unaffected participants with average (uAR) and impaired (uIR) reading. It was hypothesized that children with iCL/P would perform lower than age-expectations.

METHODS

Twenty-three males, aged 8-11 years old, were recruited through clinics, local advertisements, and state dyslexia groups (iCL/P = 7, uAR = 8, uIR = 8). Group differences on measures of cognitive processes and writing were evaluated using ANCOVA. Relationships between these measures were compared for each group through Pearson correlations.

RESULTS

Participants with iCL/P performed within the average range across all measures; group differences were only found for the uIR group. For those with iCL/P, writing was correlated to global cognitive skills rather than more specific skills.

CONCLUSIONS

While this small sample of children with iCL/P demonstrated average writing skills, patterns suggest performance is related to global cognitive reasoning rather than specific cognitive processes as found in unaffected children with impaired reading. Further research is needed to better understand writing in iCL/P and the relationship to reading and cognitive processes.

IMPACT

Research in children with isolated cleft of the lip and/or palate (iCL/P) has demonstrated higher rates of language and reading disorders. No work has assessed written expression in children with iCL/P in over 40 years. This study is the first to evaluate elements of written expression and associated cognitive processes among children with iCL/P in comparison to unaffected children with either average or impaired reading skills. Measures of writing were within the average range for children with iCL/P and demonstrated correlation to global cognitive reasoning rather than to specific cognitive processes as found in unaffected children with impaired reading.

Sex Differences in the Association of Pretransfusion Hemoglobin Levels with Brain Structure and Function in the Preterm Infant

OBJECTIVE

To assess sex-specific differences in early brain structure and function of preterm infants after red blood cell (RBC) transfusions.

STUDY DESIGN

A single-center subset of infants with a birth weight <1000 g and gestational age 22-29 weeks were enrolled from the National Institute of Child Health and Human Development's Neonatal Research Network Transfusion of Prematures Trial. Hemoglobin (Hb) concentration obtained directly before each transfusion (pretransfusion Hb [ptHb]) was obtained longitudinally throughout each infant's neonatal intensive care unit stay and used as a marker of degree of anemia (n = 97). Measures of regional brain volumes using magnetic resonance imaging were obtained at ∼40 weeks postmenstrual age or at hospital discharge, if earlier (n = 29). Measures of brain function were obtained at 12 months corrected age using the Bayley Scales of Infant & Toddler Development, 3rd Edition (n = 34).

RESULTS

PtHb was positively correlated with neonatal cerebral white matter volume in males (B = +0.283; P = .006), but not females (B = -0.099; P = .713), resulting in a significant sex interaction (P = .010). Bayley-III gross motor scores and a pooled mean score were significantly lower in association with higher ptHb in females (gross motor score: B = -3.758; P = .013; pooled mean score: B = -1.225; P = .030), but not males (gross motor score: B = +1.758; P = .167; pooled mean score: B = +0.621; P = .359). Higher ptHb was associated with descriptively lower performance on multiple Bayley-III subscales in females, but not in males.

CONCLUSIONS

This study demonstrates sex-specific associations between an early marker of anemia and RBC transfusion status (ie, ptHb) with both neonatal white matter volume and early cognitive function at age 12 months in preterm infants.

Cortical Features in Child and Adolescent Carriers of Mutant Huntingtin (mHTT)

BACKGROUND

Molecular studies provide evidence that mutant huntingtin (mHTT) affects early cortical development; however, cortical development has not been evaluated in child and adolescent carriers of mHTT.

OBJECTIVE

To evaluate the impact of mHTT on the developmental trajectories of cortical thickness and surface area.

METHODS

Children and adolescents (6-18 years) participated in the KidsHD study. mHTT carrier status was determined for research purposes only to classify participants as gene expanded (GE) and gene non-expanded (GNE). Cortical features were extracted from 3T neuroimaging using FreeSurfer. Nonlinear mixed effects models were conducted to determine if age, group, and CAG repeat were associated with cortical morphometry.

RESULTS

Age-related changes in cortical morphometry were similar across groups. Expanded CAG repeat was not significantly associated with cortical features.

CONCLUSION

While striatal development is markedly different in GE and GNE, developmental change of the cortex appears grossly normal among child and adolescent carrier of mHTT.

Characterizing academic performance in pediatric acute lymphoblastic leukemia with population-based achievement tests

BACKGROUND

Recent shifts from radiation to chemotherapy-based treatment for acute lymphoblastic leukemia (ALL) have contributed to reduced long-term morbidity. Despite this, ALL survivors remain at increased risk for long-term cognitive impairments.

AIM

To identify demographic and treatment factors associated with school performance in pediatric survivors of ALL.

METHODS

We collected standardized test scores for reading, math, and science obtained in a school setting from grades 3-11 in 63 ALL survivors (46.0% boys). Most participants were assessed across multiple grades (median number of grades n = 5, range 1-7), and 269 observations were considered in the analyses. Treatment exposures were extracted from medical records. Socio-economic status was estimated using participation in free/reduced lunch programs at school. Mixed effects linear regression models were conducted to determine factors associated with school performance.

RESULTS

ALL survivors' scores were comparable to state norms on reading, math, and science performances. On multivariable analysis, participation in free/reduced lunch programs was significantly associated with lower reading scores (β = -12.52; 95% CI -22.26:-2.77, p = .01). Exposure to radiation during treatment was also associated with lower reading test scores (β = -30.81, 95% CI -52.00:-9.62, p = .01). No significant associations between demographics and treatment parameters were observed for math and science test scores.

CONCLUSIONS

We utilized population-based achievement tests conducted from grades 3-11 to characterize school performance in ALL survivors. Our results imply that survivors with low socio-economic status and those exposed to radiation during treatment could benefit from early monitoring and intervention to maximize academic success.

Brain Developmental Trajectories in Children and Young Adults with Isolated Cleft Lip and/or Cleft Palate

The present study evaluated brain development in persons with isolated cleft lip and/or cleft palate (iCL/P) compared to unaffected controls using an accelerated longitudinal design. A sample of 134 males and females, ages 7-27 years, with iCL/P (184 observations, total) was compared to 144 unaffected controls (208 evaluations, total) on Wechsler Index scores and volumetric data from structural MRI scans. Boys with isolated cleft palate had verbal IQ 15.5 points lower than perceptual IQ; a clinically significant difference. Participants with iCL/P had differential growth trajectories of regional cerebrum matter and consistently lower volumes of cerebellar gray matter and subcortical matter.

Age-Related Cognitive Changes as a Function of CAG Repeat in Child and Adolescent Carriers of Mutant Huntingtin

Limited data exists regarding the disease course of Huntington's Disease (HD) in children and young adults. Here, we evaluate the trajectory of various cognitive skill development as a function of cytosine-adenine-guanine (CAG) repeat length in children and adolescents that carry the mutation that causes HD. We discovered that the development of verbal skills seems to plateau earlier as CAG repeat length increases. These findings increase our understanding of the relationship between neurodegeneration and neurodevelopment and may have far-reaching implications for future gene-therapy treatment strategies.

Retrospective Evaluation of Number of Surgeries and Parent Ratings of Academic and Behavioral Functioning Among Children With Isolated Oral Clefts

OBJECTIVE

The purpose of this study was to evaluate possible relationships between number of surgeries and parent ratings of academic functioning among children with isolated oral clefts.

DESIGN

Multicenter, retrospective cohort study including structured interviews, questionnaires, and chart reviews.

SETTING

Completion of questionnaires occurred during clinical visits at 6 different cleft centers across North America.

PARTICIPANTS

Parents of 285 children with isolated clefts of the lip and/or palate, aged 8 to 10 years old, participated in structured interviews and completed questionnaires regarding the academic and behavioral functioning of their children.

MAIN OUTCOME MEASURES

Parent interview and medical chart review of number of surgeries to date and parent ratings on the Adaptive Behavior Assessment System, Third Edition-Functional Academics Scale (ABAS-FA) and Child Behavior Checklist (CBCL) Total Competency Scale.

RESULTS

Parent ratings of ABAS-FA were at or above normative expectations, while ratings across CBCL Competency Scales were lower than normative expectations. Socioeconomic status (SES), age, and race were consistent predictors of parent ratings (higher SES, older age, and Caucasian race were associated with better functioning). Number of surgeries did not add significantly to academic ratings but did significantly contribute to ratings of social and activity participation. Patients with more surgeries were rated with lower functioning in these domains.

CONCLUSIONS

Findings do not support a connection between number of surgeries and later ratings of academic functioning but do support a connection to social and activity involvement. Recommendations for conducting direct studies of the connection between surgeries and academic functioning as well as clinical considerations for surgeries and impact on social and activity involvement are discussed.

Developmental Trajectory of Height, Weight, and BMI in Children and Adolescents at Risk for Huntington's Disease: Effect of mHTT on Growth

BACKGROUND

The gene (Huntingtin or HTT) causing Huntington's disease (HD) is vital for development and is expressed throughout the brain and body lifelong. The mutant form (mHTT) may influence growth and development.

OBJECTIVE

To determine the impact of mHTT on human measures of growth, including height, weight, and body mass index (BMI), between child and adolescent carriers of mHTT and control peers.

METHODS

Children ages 6-18 years of age (n = 186) at risk for HD were enrolled in the KidsHD study. For research purposes only, genetic testing was performed to classify participants as Gene-Expanded (GE = 78) or as Gene Non-Expanded (GNE = 108). Outcome measures included height, weight, and body mass index (BMI). Mixed models were used to determine if non-linear age trends differed between groups for BMI, height, and weight.

RESULTS

Differences were seen in the trajectory of BMI in which the GE group reached a plateau in late adolescence with no further increase, compared with a nearly linear increase in the GNE group. There was a significant sex interaction pattern where GE males were taller than GNE males in adolescence, in the presence of similar weight. In contrast, GE females weighed significantly less than their GNE counterparts in adolescence, in the presence of similar height.

CONCLUSION

Measures of growth are abnormal in child and adolescent carriers of mHTT, decades before HD onset. Although further studies are needed for replication, the current findings suggest that developmental aberrations may be systemic and a vital part of disease pathology.

Long-term outcome of brain structure in female preterm infants: possible associations of liberal versus restrictive red blood cell transfusions

BACKGROUND

Preterm infants who receive differential red blood cell (RBC) transfusions at birth may show brain structure differences across development, including abnormalities in white matter (WM) structure and organization. This study investigated long-term outcomes of brain structure in female infants born preterm, at an average age of 13 years old, who received red blood cell (RBC) transfusions in the neonatal period according to a liberal or restrictive approach. Results from this study will increase understanding of the effects of transfusion on the developing brain.

STUDY DESIGN AND METHODS

This follow-up study included female preterm infants who participated in a clinical trial and had been randomized at birth to either a liberal or restrictive hematocrit threshold. Brain structures were measured in childhood using structural magnetic resonance imaging (MRI) scans. Due to the low number of females in the restrictive transfusion group at follow-up, additional females were recruited for inclusion. Main outcome measures included cerebral and subcortical brain region volumes.

RESULTS

Total intracranial volume was significantly decreased in females who were randomized to higher average hematocrit levels at birth. Infants in the liberal transfusion group had proportionately smaller volumes in all measures of regional cerebral WM and subcortical brain volumes, reaching significance for temporal lobe WM and caudate volumes.

CONCLUSION

Female premature infants who received a liberal transfusion threshold at birth had decreased WM volumes, which suggests the potential long-term neurodevelopmental risks associated with liberal transfusion practices.

Abnormal brain development in child and adolescent carriers of mutant huntingtin

OBJECTIVE

The huntingtin gene is critical for the formation and differentiation of the CNS, which raises questions about the neurodevelopmental effect of CAG expansion mutations within this gene (mHTT) that cause Huntington disease (HD). We sought to test the hypothesis that child and adolescent carriers of mHTT exhibit different brain growth compared to peers without the mutation by conducting structural MRI in youth who are at risk for HD. We also explored whether the length of CAG expansion affects brain development.

METHODS

Children and adolescents (age 6-18) with a parent or grandparent diagnosed with HD underwent MRI and blinded genetic testing to confirm the presence or absence of mHTT. Seventy-five individuals were gene-expanded (GE) and 97 individuals were gene-nonexpanded (GNE). The GE group was estimated to be on average 35 years from clinical onset. Following an accelerated longitudinal design, age-related changes in brain regions were estimated.

RESULTS

Age-related striatal volume changes differed significantly between the GE and GNE groups, with initial hypertrophy and more rapid volume decline in GE. This pattern was exaggerated with CAG expansion length for CAG > 50. A similar age-dependent group difference was observed for the globus pallidus, but not in other major regions.

CONCLUSION

Our results suggest that pathogenesis of HD begins with abnormal brain development. An understanding of potential neurodevelopmental features associated with mHTT may be needed for optimized implementation of preventative gene silencing therapies, such that normal aspects of neurodevelopment are preserved as neurodegeneration is forestalled.

Female and Male Differences in Academic Achievement in Individuals With Cleft: A Population-Based Register Study

OBJECTIVE

The focus of this study was to determine if there is any significant difference in academic achievement for girls and boys with a cleft compared to the general population of Swedish students at graduation from compulsory school.

DESIGN

A retrospective population-based study using data obtained from the Swedish Medical Birth Register that was linked to the Swedish School-Grade Register.

PARTICIPANTS

Two hundred seventy girls and 241 boys with cleft palate (CP), 222 girls and 429 boys with cleft lip (CL), and 299 girls and 531 boys with cleft lip and palate (CLP) were compared with the compulsory school population comprising 609,397 girls and 640,007 boys.

MAIN OUTCOME MEASURES

(1) Odds of receiving the lowest grade and reduced odds in receiving high grades in Mathematics, English, and Swedish. (2) grade point average (GPA).

RESULTS

In all 3 subject grades, for boys with cleft there was no difference when compared to the male population. Girls with cleft were similar to their peers with a few exceptions. Girls with CLP had lower Math grades, and girls with CP had lower Math, English, and Swedish grades. Girls with CP and CLP achieved a significantly lower GPA in comparison to the female population and boys with CP and CL achieved lower GPAs in comparison to the male population.

CONCLUSIONS

This study indicates that educational outcomes for girls with cleft are more negatively affected than for boys with cleft.

Sex-specific effects of the Huntington gene on normal neurodevelopment

Huntington disease is a neurodegenerative disorder caused by a gene (HTT) with a unique feature of trinucleotide repeats ranging from 10 to 35 in healthy people; when expanded beyond 39 repeats, Huntington disease develops. Animal models demonstrate that HTT is vital to brain development; however, this has not been studied in humans. Moreover, evidence suggests that triplet repeat genes may have been vital in evolution of the human brain. Here we evaluate brain structure using magnetic resonance imaging and brain function using cognitive tests in a sample of school-aged children ages 6 to 18 years old. DNA samples were processed to quantify the number of CAG repeats within HTT. We find that the number of repeats in HTT, below disease threshold, confers advantageous changes in brain structure and general intelligence (IQ): the higher the number of repeats, the greater the change in brain structure, and the higher the IQ. The pattern of structural brain changes associated with HTT is strikingly different between males and females. HTT may confer an advantage or a disadvantage depending on the repeat length, playing a key role in either the evolution of a superior human brain or development of a uniquely human brain disease. © 2016 Wiley Periodicals, Inc.

Arithmetical calculation and related neuropsychological skills in subjects with isolated oral clefts

OBJECTIVE

The current study examined whether the arithmetical calculation skills of children, adolescents, and young adults with isolated cleft of the lip and/or palate (iCL/P) differ significantly from unaffected control participants. Comparisons of potential neuropsychological predictors of arithmetical calculation were also conducted to determine whether these variables differ significantly for participants with iCL/P.

METHOD

Participants (N = 176; 93 iCL/P and 83 Control) ranged in age from 7 to 26 years old. A standardized battery of achievement and neuropsychological skills was administered. Between group differences on math achievement was assessed through a univariate analysis of covariance. Relationships between neuropsychological measures and math achievement were analyzed separately for participants with iCL/P and controls through hierarchical linear regressions.

RESULTS

Arithmetical calculation was significantly lower for the iCL/P group. Rapid naming, sustained attention, and visual-spatial organization were significant predictors for the iCL/P group; rapid naming was the lone variable that was significantly more predictive of arithmetical calculation for the iCL/P group than for control participants.

CONCLUSIONS

These results suggest that inefficient verbal label retrieval related to short-term memory (STM) deficits underlie the calculation difficulties of individuals with iCL/P. These findings have implications for approaches to remediation, as well as future research. (PsycINFO Database Record

The Americleft Psychosocial Outcomes Project: A Multicenter Approach to Advancing Psychosocial Outcomes for Youth With Cleft Lip and Palate

Cleft lip and/or palate (CL/P) are among the most common of all birth defects. Habilitation requires multiple surgeries and other therapies throughout childhood and adolescence. While multidisciplinary care is recommended, there is a great deal of variation in treatment protocols for this condition. There is ample evidence that children with CL/P are at risk for psychosocial problems. However, to date, few studies have systematically investigated parent and patient self-reported psychosocial and quality of life (QOL) outcomes for children with CL/P as they relate to variations in treatment protocols. The Americleft Outcomes project was initiated to demonstrate and document outcomes to be expected with team care, and to define the key features or characteristics of various team treatment protocols and procedures that are associated with more or less favorable/desirable outcomes. This article will describe the psychosocial component of the Americleft Outcomes project that is aimed at developing a protocol that will allow cross team assessment of psychosocial outcomes for children with CL/P in relationship to the treatments they received. The protocol will be detailed along with a description of the process and considerations that were instrumental in the development of the project. Stakeholder input about the project's perceived relevance to families of children with CL/P will be reported. The paper concludes with a discussion of the challenges encountered with this project, clinical implications, and future directions.

The Relationship of Exposure to Anesthesia on Outcomes in Children With Isolated Oral Clefts

This study evaluated the relationship between exposure to anesthesia and previously identified differences in cognitive functioning, growth, and volumetric brain measures among a sample of children, adolescents, and young adults with isolated oral clefts. Data from a cross-sectional study were combined with a retrospective chart review. Data were obtained for 87 participants with isolated cleft lip and/or palate (55% male), ranging from 7.5 to 27 years old (mean = 15.78, standard deviation = 4.58). Measures of interest included cognitive functioning, growth measures, and brain volumes. Number of surgeries and time under anesthesia were obtained through systematic medical record review. Potential sex and cleft type differences in exposure as well as relationships between anesthesia exposure and outcome measures were evaluated. Participants with isolated cleft lip and palate had more surgeries and were under anesthesia longer. For participants with isolated cleft lip only, more surgeries were correlated to lower verbal IQ and higher frontal lobe volume.

Altered brain function, structure, and developmental trajectory in children born late preterm

BACKGROUND

Late preterm birth (34-36 wk gestation) is a common occurrence with potential for altered brain development.

METHODS

This observational cohort study compared children at age 6-13 y based on the presence or absence of the historical risk factor of late preterm birth. Children completed a battery of cognitive assessments and underwent magnetic resonance imaging of the brain.

RESULTS

Late preterm children (n = 52) demonstrated slower processing speed (P = 0.035) and scored more poorly in visual-spatial perception (P = 0.032) and memory (P = 0.007) than full-term children (n = 74). Parents of late preterm children reported more behavioral difficulty (P = 0.004). There were no group differences in cognitive ability or academic achievement. Imaging revealed similar intracranial volumes but less total tissue and more cerebrospinal fluid (P = 0.004) for late preterm children compared to full-term children. The tissue difference was driven by differences in the cerebrum (P = 0.028) and distributed across cortical (P = 0.051) and subcortical tissue (P = 0.047). Late preterm children had a relatively smaller thalamus (P = 0.012) than full-term children. Only full-term children demonstrated significant decreases in cortical tissue volume (P < 0.001) and thickness (P < 0.001) with age.

CONCLUSION

Late preterm birth may affect cognition, behavior, and brain structure well beyond infancy.

Reading Achievement in Boys With Non-Syndromic Cleft Palate Only: Relationship to Neuropsychological Skill and Neurocircuitry

Reading achievement and neural activation during a reading task were evaluated among boys with isolated cleft palate only (iCP) in comparison to unaffected controls. Ten boys with iCP and 10 unaffected boys between the ages of 8 and 16 years old were assessed. Standardized assessments of intelligence and reading achievement were administered and participants underwent a block-design functional magnetic resonance imaging protocol using non-word rhyming and judgment of line tasks. Among the 10 boys with iCP, reading fluency correlated with phonological awareness and visual memory. Neural activation was increased in regions of the brain associated with a non-fluent/dyslexic reading pattern.

Morphometric analysis of brain shape in children with nonsyndromic cleft lip and/or palate

The purpose of this study was to test for differences in brain shape among children with cleft palate only (n = 22), children with cleft lip and palate (n = 35), and controls (n = 39) using Euclidean distance matrix analysis. Sixteen percent of interlandmark distances differed between children with cleft palate only and controls, 10% differed between children with cleft lip and palate and controls, and 10% differed between children with cleft palate only and children with cleft lip and palate. Major differences in brain shape associated with cleft lip and/or palate included posterior expansion of the occipital lobe, reorientation of the cerebellum, heightened callosal midbody, and posterior displacement of the caudate nucleus and thalamus. Differences in brain shape unique to cleft palate only and to cleft lip and palate were also identified. These results expand upon previous volumetric studies on brain morphology in individuals with cleft lip and/or palate and provide additional evidence that the primary defect in cleft lip and/or palate results in both facial and brain dysmorphology.

The relationship between brain structure and cognition in transfused preterm children at school age

Examine the relationship between brain structure and cognition in preterm children randomly assigned to a liberal red blood cell (RBC) transfusion strategy as neonates. Intelligence, achievement, and neuropsychological measures were assessed and structural imaging was obtained (n = 26; 38% male). Global brain volumes were related to cognitive outcome. Additionally, females performed lower on verbal fluency; lower performance was related to temporal white matter volume. Findings provide possible evidence of the adverse effect of a liberal RBC transfusion strategy in which females had decreased temporal lobe white matter directly related to poor verbal fluency.

Reading in subjects with an oral cleft: speech, hearing and neuropsychological skills

OBJECTIVE

To evaluate speech, hearing, and neuropsychological correlates to reading among children, adolescents, and young adults with nonsyndromic cleft of the lip and/or palate (NSCL/P).

METHOD

All testing was completed in a single visit at a Midwestern university hospital. Subjects in both the NSCL/P (n = 80) and the control groups (n = 62) ranged in age from 7-26 years (average age = 17.60 and 17.66, respectively). Subjects completed a battery of standardized tests evaluating intelligence, neuropsychological skills, and word reading. Subjects with NSCL/P also underwent speech assessment, and past audiology records were evaluated.

RESULTS

After controlling for age and socioeconomic status, subjects with cleft performed significantly worse on a test of word reading. For subjects with cleft, word reading deficits were not associated with measures of speech or hearing, but were correlated with impairments in auditory memory.

CONCLUSION

These findings show poorer reading among subjects with NSCL/P compared with those without. Further work needs to focus on correlates of reading among subjects with cleft to allow early identification and appropriate intervention/accommodation for those at risk.

Masculinity/femininity predicts brain volumes in normal healthy children

Previous research has shown sex differences in brain morphology ( De Bellis et al., 2001 ). However, these studies have not taken gender into account. Gender is a phenotype that describes behavior. In this study, we examined the relationship between gender, sex, and brain volumes in children. One hundred and eight children ages 7 to 17 were administered the Children's Sex Role Inventory ( Boldizar, 1991 ) and obtained volumetric brain data via magnetic resonance imaging (MRI). We found that, in the frontal lobe, higher masculinity predicted greater volumes of white matter. Also, in the temporal lobe, higher femininity predicted greater volumes of gray matter.

Abnormal cerebellar structure is dependent on phenotype of isolated cleft of the lip and/or palate

Isolated cleft lip and/or palate (ICLP) is one of the most common congenital birth defects in the USA, affecting roughly 1 in 600 births annually. Along with the facial deformity, this population has been found to have abnormal neurodevelopment and gross structural abnormalities in the brain, particularly within the cerebellum. The current study examined cerebellar structure within the two primary subtypes of ICLP: cleft lip with/without cleft palate (CL/P) and cleft palate alone (CPO). A large sample of 107 subjects aged 7 to 27 years with ICLP was compared to 127 healthy controls. Samples were separated by sex. Brain structure was obtained via magnetic resonance imaging. For males, after controlling for intracranial volume, cerebellum volume was significantly lower in the ICLP group (F = 12.351, p = 0.001). Regionally in the cerebellum, males with ICLP had proportionally larger anterior lobes (F = 4.022, p = 0.047) and smaller superior posterior lobes (F = 5.686, p = 0.019). CL/P males showed only a reduction in overall cerebellum volume, with no regional changes. CPO males showed only regional changes, with no reduction in overall volume. Females with ICLP showed no overall or regional cerebellar abnormalities. However, females with CPO did have significantly lower cerebellum volumes than controls. The results reveal both global and regional cerebellar abnormalities within subjects with ICLP. They also establish the existence of abnormal cerebellar morphologies that are dependent on cleft subtype as well as sex. This lends further support to the claim that CL/P and CPO are distinct conditions.

Social motivation in individuals with isolated cleft lip and palate

Social isolation is common among individuals with isolated cleft lip and palate (ICLP), but the available data on why this may be are mixed. We present a novel theory relating to reduced social motivation in ICLP, called the social abulia hypothesis. Based on this hypothesis, we predicted that reduced social motivation would lead to reduced responsiveness to negative social feedback, in terms of both explicit responses and noncontrolled, psychophysiological responses. Twenty males with ICLP and 20 normal comparison males between 13 and 25 years old participated in the study. Social motivation was examined by measuring participants' response to negative social feedback (social exclusion). Additionally, psychophysiological reactivity to positive and negative social stimuli was measured. In order to rule out other potential contributors to social isolation, we tested basic social perception, emotion recognition, and social anxiety. In line with the social abulia hypothesis, we show that negative social feedback had less of an effect on males with ICLP than on healthy male peers, which was evident in explicit responses and noncontrolled, psychophysiological responses to negative social feedback. Our results could not be attributed to problems in social perception, a lack of understanding facial expressions, or increased social anxiety, as groups did not differ on these constructs. This study suggests that current views on social isolation in ICLP may need to be reconsidered to include the possibility that isolation in this population may be the direct result of reduced social motivation.

Corpus callosum shape is altered in individuals with nonsyndromic cleft lip and palate

Individuals with nonsyndromic cleft lip with or without cleft palate (CL/P) have altered brain structure compared with healthy controls. Preliminary evidence suggests that the corpus callosum may be dysmorphic in orofacial clefting; however, this midline brain structure has not been systematically assessed in this population. The goal of the present study was to carry out a morphometric assessment of the corpus callosum and its relationship to cognitive performance in a well-characterized patient cohort with orofacial cleft. Midline brain images were obtained from previously collected MRI scans of 24 CL/P subjects and 40-adult-male controls. Eight landmarks on the corpus callosum were digitized on each image and their x,y coordinate locations saved. A geometric morphometrics analysis was applied to the landmark coordinate data to test for shape differences across groups. The relationship between corpus callosum shape and IQ was explored with nonparametric correlation coefficients. Results revealed significant differences in mean corpus callosum shape between CL/P cases and controls (P = 0.029). The CL/P corpus callosum was characterized by increased overall convexity resulting from a superior and posterior displacement. Within CL/P cases, increased corpus callosum shape dysmorphology was moderately correlated with reduced performance IQ (r = 0.546). These results provide additional evidence that midline brain changes may be an important part of the orofacial cleft phenotype.

Memory processes in learning disability subtypes of children born preterm

The purpose of this study was to evaluate immediate auditory and visual memory processes in learning disability subtypes of 40 children born preterm. Three subgroups of children were examined: (a) primary language disability group (n = 13), (b) perceptual-motor disability group (n = 14), and (c) no learning disability diagnosis group without identified language or perceptual-motor learning disability (n = 13). Between-group comparisons indicate no significant differences in immediate auditory or visual memory performances between language and perceptual-motor learning disability groups. Within-group comparisons revealed that both learning disability groups performed significantly lower on a task of immediate memory when the mode of stimulus presentation and mode of response were visual.

Neuropsychological, behavioral, and academic sequelae of cleft: early developmental, school age, and adolescent/young adult outcomes

This article reviews behavioral, neuropsychological, and academic outcomes of individuals with cleft across three age levels: (1) infancy/early development, (2) school age, and (3) adolescence/young adulthood. The review points out that attachment, neurocognitive functioning, academic performance/learning, and adjustment outcomes are the result of a complex interaction between biological and environmental factors and vary with developmental level, sex, and craniofacial anomaly diagnosis. The degree to which associated genetic or neurodevelopmental conditions may explain inconsistent findings is unknown and suggests the need for caution in generalizing from group data on cleft.

Long-term outcome of brain structure in premature infants: effects of liberal vs restricted red blood cell transfusions

OBJECTIVE

To assess the long-term outcome of brain structure in preterm infants, at an average age of 12 years, who received a red blood cell transfusion for anemia of prematurity.

DESIGN

As neonates, this cohort of infants participated in a clinical trial in which they received red blood cell transfusions based on a high pretransfusion hematocrit threshold (liberal group) or a low hematocrit threshold (restricted group). These 2 preterm groups were compared with a group of full-term healthy control children.

SETTING

Tertiary care hospital.

PARTICIPANTS

Magnetic resonance imaging scans for 44 of the original 100 subjects were obtained.

INTERVENTION

Liberal vs restricted transfusion.

MAIN OUTCOME MEASURES

Intracranial volume, total brain tissue, total cerebrospinal fluid, cerebral cortex and cerebral white matter volume, subcortical nuclei volume, and cerebellum volume.

RESULTS

Intracranial volume was substantially smaller in the liberal group compared with controls. Intracranial volume in the restricted group was not different from controls. Whole-cortex volume was not different in either preterm group compared with controls. Cerebral white matter was substantially reduced in both preterm groups, more so for the liberal group. The subcortical nuclei were substantially decreased in volume, equally so for both preterm groups compared with controls. When sex effects were evaluated, the girls in the liberal group had the most significant abnormalities.

CONCLUSION

Red blood cell transfusions affected the long-term outcome of premature infants as indicated by reduced brain volumes at 12 years of age for neonates who received transfusions using liberal guidelines.

Neurocognitive profiles of preterm infants randomly assigned to lower or higher hematocrit thresholds for transfusion

OBJECTIVE

Preterm infants are frequently transfused with red blood cells based on standardized guidelines or clinical concerns that anemia taxes infants' physiological compensatory mechanisms and thereby threatens their health and well-being. The impact of various transfusion guidelines on long-term neurocognitive outcome is not known. The purpose of this study is to evaluate long-term neurocognitive outcome on children born prematurely and treated at birth with different transfusion guidelines.

METHODS

Neurocognitive outcomes were examined at school age for 56 preterm infants randomly assigned to a liberal (n = 33) or restrictive (n = 23) transfusion strategy. Tests of intelligence, achievement, language, visual-spatial/motor, and memory skills were administered. Between-group differences were assessed.

RESULTS

Those in the liberal transfusion group performed more poorly than those in the restrictive group on measures of associative verbal fluency, visual memory, and reading.

CONCLUSIONS

Findings highlight possible long-term neurodevelopmental consequences of maintaining higher hematocrit levels.

Hyperactivity, impulsivity, and inattention in boys with cleft lip and palate: relationship to ventromedial prefrontal cortex morphology

The purpose of this study is to evaluate quantitative structural measures of the ventromedial prefrontal cortex (vmPFC) in boys with isolated clefts of the lip and/or palate (ICLP) relative to a comparison group and to associate measures of brain structure with quantitative measures of hyperactivity, impulsivity, and inattentiveness. A total of 50 boys with ICLP were compared to 60 healthy boys without clefts. Magnetic resonance imaging brain scans were used to evaluate vmPFC structure. Parents and teachers provided quantitative measures of hyperactivity, impulsivity, and inattentiveness using the Pediatric Behavior Scale. Boys with ICLP had significantly higher ratings of hyperactivity/impulsivity/inattention (HII) and significantly increased volume of the right vmPFC relative to the comparison group. There was a direct relationship between HII score and vmPFC volume in both the ICLP group and control group, but the relationship was in the opposite direction: in ICLP, the higher the vmPFC volume, the higher the HII score; for the comparison group, the lower the vmPFC volume, the greater the HII score. The vmPFC is a region of the brain that governs behaviors of hyperactivity, impulsivity and inattention (HII). In boys with ICLP, there are higher levels of HII compared to the controls and this is directly related to a significantly enlarged volume of the right vmPFC. Enlargement of this region of the brain is therefore considered to be pathological in the ICLP group and supports the notion that abnormal brain structure (from abnormal brain development) is the underlying etiology for the abnormal behaviors seen in this population.

Cerebellum structure differences and relationship to speech in boys and girls with nonsyndromic cleft of the lip and/or palate

OBJECTIVE

To identify regional cerebellar structural differences in boys and girls with nonsyndromic cleft of the lip and/or palate and determine whether these differences are related to speech impairment.

DESIGN

Between 2003 and 2007, measures on cerebellar volume were obtained on 43 children with nonsyndromic cleft of the lip and/or palate and 43 age- and sex-matched, healthy controls. Children with the cleft condition also received speech evaluations. Children with nonsyndromic cleft of the lip and/or palate were recruited from clinic records, and controls (screened for medical, psychiatric, speech/language, and behavioral concerns) were recruited from the local community. All tests were administered at a large midwestern hospital. Boys and girls with nonsyndromic cleft of the lip and/or palate were compared with the healthy controls on global and regional measures of cerebellar volume. Areas of significant difference were then correlated with measures of speech to assess relationships in children with nonsyndromic cleft of the lip and/or palate.

RESULTS

Boys with nonsyndromic cleft of the lip and/or palate had smaller cerebellums than controls (p = .002); whereas, for girls, only regional reductions in size reached significance (corpus medullare, p = .040). Cerebellum size was correlated with articulation for boys (p = .045).

CONCLUSIONS

These findings lend support to previous research documenting abnormal brain structure in children with nonsyndromic cleft of the lip and/or palate and suggest that the cerebellum may play a role in speech deficits along with other structural causes, at least in boys.

Biological and environmental predictors of behavioral sequelae in children born preterm

OBJECTIVE

By using behavioral outcome measures of children who were born preterm, we evaluated differences between children who were born at term and children who were born at extremely low (ELBW; <1000 g) and very low birth weights (VLBW; 1000-1499 g) and assessed the relationship of birth weight, socioeconomic status, and cognitive ability to behavioral outcome.

METHODS

We studied a total of 104 children (aged 7-16 years). Of these, 49 had a preterm birth (31 of ELBW and 18 of VLBW). The remaining 55 were healthy control subjects. Children were administered tests of cognitive ability. Parents and teachers completed behavioral assessments. Multivariate analyses of covariance assessed differences between children who were born at term and those who were born of ELBW and of VLBW on behavioral measures. Hierarchical linear regressions were used to assess relationships among biological (birth weight), environmental (socioeconomic status), intellectual, and behavioral variables.

RESULTS

Children who were born at term had fewer parent reports of hyperactivity/inattention and depression/anxiety symptoms than children of ELBW and VLBW. Teacher ratings were not significant between groups. Birth weight was consistently the strongest predictor of parent ratings of behavioral outcome, and intelligence level did not seem to mediate this relationship.

CONCLUSIONS

Negative behavioral sequelae of preterm birth remain significant in middle childhood and adolescence, although the contribution of multiple factors to neurobehavioral outcome is complex. Research to assess these relationships, integrated with anatomic and functional neuroimaging, is needed to advance knowledge and improve outcomes for children who are born preterm.

Specialized Summer Camp for Children with Cancer: Social Support and Adjustment

The purpose of this study was to assess the types of social support received by children attending a week-long residential summer camp for children with cancer. Following the camp, families were sent a social support questionnaire (for the child to complete) and the Child Behavior Checklist (for parents to complete). Analyses evaluated children's adjustment rated by parents, support reported by children, and the relationship between adjustment and support. Girls reported receiving more support than boys, and both genders reported receiving more support at camp than children in the general population. Ratings of adjustment were not different from normative data for boys or girls. No relationship was found between adjustment and support. The camp environment is very supportive and may offer forms of support not available in other environments. Research is needed to further understand how camp can be supportive, what factors may affect that support, and how the experience enhances children's quality of life.

Incidence of neurological soft signs in children with isolated cleft of the lip or palate

The purpose of this study was to assess neurological soft signs in children and adolescents with isolated cleft of the lip or palate (iCL/P) compared with healthy controls. Children with iCL/P were recruited through the university cleft clinic. Control subjects were recruited through advertisements. Of the 166 subjects who participated (age range 7 to 17 years, M = 12.5, SD = 3.2), 77 had iCL/P (48 male) and 89 were healthy controls (44 male). All participants took the Physical and Neurological Examination of Subtle Signs and selected tests of motor coordination. A multivariate analysis of variance assessed differences between subjects with and without iCL/P. Also, a Pearson correlation estimated the relationship between the neurological soft signs and age. Subjects with iCL/P scored significantly higher on all neurological soft signs variables. These higher scores were associated with younger age. Findings lend support to the hypothesis of aberrant brain development in children with iCL/P.
