COVID-19 preparedness-a survey among neonatal care providers in low- and middle-income countries.
Journal of perinatology : official journal of the California Perinatal Association
OBJECTIVE: To evaluate COVID-19 pandemic preparedness, available resources, and guidelines for neonatal care delivery among neonatal health care providers in low- and middle-income countries (LMICs) across all continents.STUDY DESIGN: Cross-sectional, web-based survey administered between May and June, 2020.RESULTS: Of 189 invited participants in 69 LMICs, we received 145 (77%) responses from 58 (84%) countries. The pandemic provides significant challenges to neonatal care, particularly in low-income countries. Respondents noted exacerbations of preexisting shortages in staffing, equipment, and isolation capabilities. In Sub-Saharan Africa, 9/35 (26%) respondents noted increased mortality in non-COVID-19-infected infants. Clinical practices on cord clamping, isolation, and breastfeeding varied widely, often not in line with World Health Organization guidelines. Most respondents noted family access restrictions, and limited shared decision-making.CONCLUSIONS: Many LMICs face an exacerbation of preexisting resource challenges for neonatal care during the pandemic. Variable approaches to care delivery and deviations from guidelines provide opportunities for international collaborative improvement.

International comparison of guidelines for managing neonates at the early phase of the SARS-CoV-2 pandemic.
The COVID-19 pandemic threatens global newborn health. We describe the current state of national and local protocols for managing neonates born to SARS-CoV-2-positive mothers.Care providers from neonatal intensive care units on six continents exchanged and compared protocols on the management of neonates born to SARS-CoV-2-positive mothers. Data collection was between March 14 and 21, 2020. We focused on central protocol components, including triaging, hygiene precautions, management at delivery, feeding protocols, and visiting policies.Data from 20 countries were available. Disease burden varied between countries at the time of analysis. In most countries, asymptomatic infants were allowed to stay with the mother and breastfeed with hygiene precautions. We detected discrepancies between national guidance in particular regarding triaging, use of personal protection equipment, viral testing, and visitor policies. Local protocols deviated from national guidance.At the start of the pandemic, lack of evidence-based guidance on the management of neonates born to SARS-CoV-2-positive mothers has led to ad hoc creation of national and local guidance. Compliance between collaborators to share and discuss protocols was excellent and may lead to more consensus on management, but future guidance should be built on high-level evidence, rather than expert consensus.At the rapid onset of the COVID19 pandemic, all countries presented protocols in place for managing infants at risk of COVID19, with a certain degree of variations among regions. A detailed review of ad hoc guidelines is presented, similarities and differences are highlighted. We provide a broad overview of currently applied recommendations highlighting the need for international context-relevant coordination.

Demographic and psychosocial factors associated with hair cortisol concentrations in preschool children.
BACKGROUND: Early life stress has enduring effects on physical and mental health. Hair cortisol concentrations (HCCs) reflect exposures to contextual stressors in early life, but are understudied in preschool children.METHODS: Hair samples from children (N=693) during clinic visits (CVs) scheduled at 1-4 years (CV1-CV4) were measured using validated assay methods for HCC.RESULTS: HCCs were highest at CV1 and decreased at CV2-CV4, with no sex differences. Black children had higher HCC than White/other children; these differences persisted even after adjusting for socioeconomic factors. Bivariable analyses showed significant effects on HCC for Black race, with specific demographic and psychosocial factors at different ages. Multivariable analyses showed that higher HCC at CV1 were associated with Black race and male sex; at CV2 with Black race, lower maternal self-esteem, socioeconomic adversity, and the child's risk for developmental delay; at CV3 with Black race; at CV4 with maternal depression and the child's prior HCC values.CONCLUSIONS: HCCs were higher in Black children than White/other races; differences were related to maternal factors, socioeconomic adversity, and the child's risk for developmental delay. Public health measures to reduce disparities between Blacks and other races must also consider the long-term effects of chronic stress in early life.

P300 amplitude attenuation in high risk and early onset psychosis youth.
Little research has investigated the use of electrophysiological biomarkers in childhood and adolescence to distinguish early onset psychosis and the clinical high risk state. The P300 evoked potential is a robust neurophysiological marker of schizophrenia that is dampened in patients with schizophrenia and, less consistently, in those with affective psychoses and those at clinical high risk for psychosis (CHR). How it may differ between patients with psychotic disorders (PS) and CHR is less studied, especially in youth. The current study compared P300 activity among children and adolescents, aged 5-18 years, at CHR (n = 43), with PS (n = 28), and healthy controls (HC; n = 24). Participants engaged in an auditory event-related potential (ERP) task to elicit a P300 response and completed clinical interviews to verify symptoms and diagnoses. Linear regression analyses revealed a decrease in P300 amplitude with increased severity of psychotic symptoms. PS participants showed a diminished P300 response compared to those at CHR and HC, particularly among adolescents aged 13-18. This response was most evident at centroparietal and parietal locations in the right hemisphere. The findings suggest that high risk and psychotic symptomatology is linked to attenuated parietal P300 activity in youth as young as 13 years. Further exploration of the P300 as a biomarker for psychosis in very young patients could inform tailored, appropriate interventions at early stages of disease progression. Future research should evaluate whether specific phenotypic and genotypic characteristics are differentially associated with neurophysiological biomarkers and whether P300 attenuation in CHR youth can predict later symptom severity.

De novo variant of TRRAP in a patient with very early onset psychosis in the context of non-verbal learning disability and obsessive-compulsive disorder: a case report
BMC MEDICAL GENETICS
2018; 19: 197
TRRAP encodes a multidomain protein kinase that works as a genetic cofactor to influence DNA methylation patterns, DNA damage repair, and chromatin remodeling. TRRAP protein is vital to early neural developmental processes, and variants in this gene have been associated with schizophrenia and childhood disintegrative disorder.Here, we report on a patient with a de novo nonsynonymous TRRAP single-nucleotide variant (EST00000355540.3:c.5957G > A, p.Arg1986Gln) and early onset major depression accompanied by a psychotic episode (before age 10) that occurred in the context of longer standing nonverbal learning disability and a past history of obsessions and compulsions.The de novo variant and presentation of very early onset psychosis indicate a rare Mendelian disorder inheritance model. The genotype and behavioral abnormalities of this patient are reviewed.

De novo ATP1A3 and compound heterozygous NLRP3 mutations in a child with autism spectrum disorder, episodic fatigue and somnolence, and muckle-wells syndrome.
Molecular genetics and metabolism reports
2018; 16: 23-29
Complex phenotypes may represent novel syndromes that are the composite interaction of several genetic and environmental factors. We describe an 9-year old male with high functioning autism spectrum disorder and Muckle-Wells syndrome who at age 5 years of age manifested perseverations that interfered with his functioning at home and at school. After age 6, he developed intermittent episodes of fatigue and somnolence lasting from hours to weeks that evolved over the course of months to more chronic hypersomnia. Whole exome sequencing showed three mutations in genes potentially involved in his clinical phenotype. The patient has a predicted pathogenic de novo heterozygous p.Ala681Thr mutation in the ATP1A3 gene (chr19:42480621C>T, GRCh37/hg19). Mutations in this gene are known to cause Alternating Hemiplegia of Childhood, Rapid Onset Dystonia Parkinsonism, and CAPOS syndrome, sometimes accompanied by autistic features. The patient also has compound heterozygosity for p.Arg490Lys/p.Val200Met mutations in the NLRP3 gene (chr1:247588214G>A and chr1:247587343G>A, respectively). NLRP3 mutations are associated in an autosomal dominant manner with clinically overlapping auto-inflammatory conditions including Muckle-Wells syndrome. The p.Arg490Lys is a known pathogenic mutation inherited from the patient's father. The p.Val200Met mutation, inherited from his mother, is a variant of unknown significance (VUS). Whether the de novoATP1A3mutation is responsible for or plays a role in the patient's episodes of fatigue and somnolence remains to be determined. The unprecedented combination of two NLRP3 mutations may be responsible for other aspects of his complex phenotype.

Potentially traumatic events in youth with and at clinical high risk for psychosis.
Early intervention in psychiatry
Previous research has demonstrated a strong association between early trauma exposure and the development of psychotic symptoms. However, few of these studies have included young adolescents and children. This study investigated rates and number of potentially traumatic experiences (PTEs) among typically developing youth (TD; n = 21), youth at clinical high risk for psychosis (CHR; n = 38), and youth with a psychotic disorder (PD; n = 28) between 7 and 18 years of age. CHR participants were further evaluated to determine whether a history of PTEs was associated with prodromal symptom severity.Study group inclusion was determined by structured interviews. Trauma history was assessed using the post-traumatic stress disorder module of the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version. CHR participants with vs without a history of PTEs were compared on severity of prodromal symptoms.CHR and PD participants reported significantly higher rates and numbers of PTEs than TD participants. Contrary to expectations and prior research, CHR participants with vs without a history of PTEs did not differ in prodromal symptom severity. Explanations and implications for the findings are discussed.These findings suggest that the relationship between trauma and the development of psychotic symptoms extends to children and adolescents as young as 7 years of age. This study underscores the importance of screening for trauma exposure among youth seeking treatment for psychotic symptoms.

Young children with psychotic symptoms and risk for suicidal thoughts and behaviors: a research note.
BMC research notes
2018; 11 (1): 568
Suicidal thoughts and behaviors (STBs) are prevalent among youth with psychotic disorders (PD) relative to the general population. Recent research now suggests that STBs may present during the prodromal phase of the disease, or the clinical high risk (CHR) state. While this knowledge is important for the development of suicide prevention strategies in adolescent and adult populations, it remains unclear whether risk for suicide extends to children with or at risk for psychosis. The current study is an extension of previous work assessing STBs in youth across the psychosis continuum. We examine STBs in 37 CHR and PD children ages 7-13 years old, and further explore the prodromal symptom correlates of STB severity among CHR children.CHR and PD children endorsed STBs with a frequency and severity similar to what is observed in older CHR and PD populations. A number of children had never previously vocalized their suicidal plans or intent. Among CHR children, Social Anhedonia and Odd Behavior or Appearance were significantly correlated with STB severity. These findings underscore the importance of screening for STBs even in young children presenting with psychotic symptoms.

Suicidal behaviors and their relationship with psychotic-like symptoms in children and adolescents at clinical high risk for psychosis.
2017; 78: 31-37
Previous research has demonstrated elevated rates of suicide attempts and ideation in individuals with psychosis. This study investigated rates and severity of suicidal behavior in youth with and at clinical high risk for psychosis, and examined the positive, negative, and disorganized symptoms associated with suicidal behaviors among the clinical high risk group.Eighty-six youth ages 7-18 (n=21 non-clinical controls [NCC], n=40 clinical high risk [CHR], n=25 diagnosed psychotic disorder [PD]) were recruited. CHR and PD participants were identified using the Structured Interview for Prodromal Symptoms (SIPS) and Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version (KSADS-PL). All participants completed the Suicide Behaviors Questionnaire-Revised (SBQ-R).Findings indicated significantly higher levels of suicidal behavior among CHR and PD relative to NCC participants (F=7.64, p=0.001). 17.5% of CHR participants had previously attempted suicide. Dysphoric Mood and Odd Behavior or Appearance were significantly correlated with suicidal behavior severity among CHR youth.Suicidal behavior was observed with greater frequency and severity in the CHR and PD groups than in the NCC group. CHR suicidal behavior severity was correlated most strongly with Dysphoric Mood and Odd Behavior or Appearance, a relationship which warrants further investigation.

Suicidal behaviors in children and adolescents with psychotic disorders.
2017; 179: 13-16
Suicide is the leading cause of premature death in individuals with psychotic disorders. Risk for onset of suicidal behaviors tends to begin in adolescence, remaining high into young adulthood. The present study aims to evaluate the interplay of early onset psychosis and suicide risk by examining suicidal behaviors (ideation, planning, and attempts) in children and adolescents with psychotic disorders (PD) compared to typically developing peers (TD). Twenty five youths were recruited and were diagnostically evaluated for psychosis. We found that the PD children exhibited significantly higher levels of suicidal behaviors than TD children, even when parsed into individual at-risk behaviors.

A novel de novo mutation in ATP1A3 and childhood-onset schizophrenia.
Cold Spring Harbor molecular case studies
2016; 2 (5)
We describe a child with onset of command auditory hallucinations and behavioral regression at 6 yr of age in the context of longer standing selective mutism, aggression, and mild motor delays. His genetic evaluation included chromosomal microarray analysis and whole-exome sequencing. Sequencing revealed a previously unreported heterozygous de novo mutation c.385G>A in ATP1A3, predicted to result in a p.V129M amino acid change. This gene codes for a neuron-specific isoform of the catalytic α-subunit of the ATP-dependent transmembrane sodium-potassium pump. Heterozygous mutations in this gene have been reported as causing both sporadic and inherited forms of alternating hemiplegia of childhood and rapid-onset dystonia parkinsonism. We discuss the literature on phenotypes associated with known variants in ATP1A3, examine past functional studies of the role of ATP1A3 in neuronal function, and describe a novel clinical presentation associated with mutation of this gene.

Overlapping 16p13.11 deletion and gain of copies variations associated with childhood onset psychosis include genes with mechanistic implications for autism associated pathways: Two case reports.
American journal of medical genetics. Part A
2016; 170A (5): 1165-1173
Copy number variability at 16p13.11 has been associated with intellectual disability, autism, schizophrenia, epilepsy, and attention-deficit hyperactivity disorder. Adolescent/adult- onset psychosis has been reported in a subset of these cases. Here, we report on two children with CNVs in 16p13.11 that developed psychosis before the age of 7. The genotype and neuropsychiatric abnormalities of these patients highlight several overlapping genes that have possible mechanistic relevance to pathways previously implicated in Autism Spectrum Disorders, including the mTOR signaling and the ubiquitin-proteasome cascades. A careful screening of the 16p13.11 region is warranted in patients with childhood onset psychosis.

N100 Repetition Suppression Indexes Neuroplastic Defects in Clinical High Risk and Psychotic Youth
Highly penetrant mutations leading to schizophrenia are enriched for genes coding for N-methyl-D-aspartate receptor signaling complex (NMDAR-SC), implicating plasticity defects in the disease's pathogenesis. The importance of plasticity in neurodevelopment implies a role for therapies that target these mechanisms in early life to prevent schizophrenia. Testing such therapies requires noninvasive methods that can assess engagement of target mechanisms. The auditory N100 is an obligatory cortical response whose amplitude decreases with tone repetition. This adaptation may index the health of plasticity mechanisms required for normal development. We exposed participants aged 5 to 17 years with psychosis (n = 22), at clinical high risk (CHR) for psychosis (n = 29), and healthy controls (n = 17) to an auditory tone repeated 450 times and measured N100 adaptation (mean amplitude during first 150 tones - mean amplitude during last 150 tones). N100 adaptation was reduced in CHR and psychosis, particularly among participants <13 years old. Initial N100 blunting partially accounted for differences. Decreased change in the N100 amplitude with tone repetition may be a useful marker of defects in neuroplastic mechanisms measurable early in life.

Early auditory processing evoked potentials (N100) show a continuum of blunting from clinical high risk to psychosis in a pediatric sample.
2015; 169 (1-3): 340-345
The N100 is a negative deflection in the surface EEG approximately 100 ms after an auditory signal. It has been shown to be reduced in individuals with schizophrenia and those at clinical high risk (CHR). N100 blunting may index neural network dysfunction underlying psychotic symptoms. This phenomenon has received little attention in pediatric populations.This cross-sectional study compared the N100 response measured via the average EEG response at the left medial frontal position FC1 to 150 sinusoidal tones in participants ages 5 to 17 years with a CHR syndrome (n=29), a psychotic disorder (n=22), or healthy controls (n=17).Linear regression analyses that considered potential covariates (age, gender, handedness, family mental health history, medication usage) revealed decreasing N100 amplitude with increasing severity of psychotic symptomatology from healthy to CHR to psychotic level.Longitudinal assessment of the N100 in CHR children who do and do not develop psychosis will inform whether it predicts transition to psychosis and if its response to treatment predicts symptom change.
