Psychiatric co-morbidity in children and adolescents with CHDs: a systematic review.

The population of long-term survivors with CHDs is increasing due to better diagnostics and treatment. This has revealed many co-morbidities including different neurocognitive difficulties. However, the prevalence of psychiatric disorders among children and adolescents and the specific types of disorders they may experience are unclear. We systematically reviewed the existing literature, where psychiatric diagnoses or psychiatric symptoms were investigated in children and adolescents (age: 2-18 aged) with CHDs and compared them with a heart-healthy control group or normative data. The searches were done in the three databases PubMed, psychINFO, and Embase. We included 20 articles reporting on 8035 unique patients with CHDs. Fourteen articles repoted on psychological symptoms, four reported on psychiatric diagnoses, and two reported on both symptoms and diagnoses. We found that children and adolescents with a CHD had a higher prevalence of attention deficit hyperactivity disorder (ranging between 1.4 and 9 times higher) and autism (ranging between 1.8 and 5 times higher) than controls, but inconsistent results regarding depression and anxiety.

Structure, microstructure and disorder in low temperature chemical vapor deposited SiC coatings

Chemical vapor deposited SiC coatings were investigated at different scales by X-Ray diffraction, Raman microspectroscopy and transmission electron microscopy. They were prepared under specific conditions explaining the various (micro)structures obtained. The deposits all have a columnar morphology with a preferential orientation and a faulted cubic structure. They differ in how disorder is incorporated in the structure. Fine XRD analyses and stacking fault density assessment by TEM revealed the one-dimensionally-disordered (ODD) polytype in the <111> textured coatings. The frequency and spatial distribution of stacking faults vary and sometimes locally generate periodic alpha sequences. A specific type of disorder was also identified where {111} planes are arranged parallel to the growth direction within the columns. These disorders, more energetic than stacking faults, induce multiple and particularly large Raman modes. Crystal distortions, such as dislocations, are localized at the ODD domain boundaries, which are frequently interrupted as they extend during the growth.

Association between COVID-19 risk-mitigation behaviors and specific mental disorders in youth

BackgroundAlthough studies of adults show that pre-existing mental disorders increase risk for COVID-19 infection and severity, there is limited information about this association among youth. Mental disorders in general as well as specific types of disorders may influence the ability to comply with risk-mitigation strategies to reduce COVID-19 infection and transmission.MethodsYouth compliance (rated as “Never,” “Sometimes,” “Often,” or “Very often/Always”) with risk mitigation was reported by parents on the CoRonavIruS Health Impact Survey (CRISIS) in January 2021. The sample comprised 314 female and 514 male participants from the large-scale Child Mind Institute Healthy Brain Network, a transdiagnostic self-referred, community sample of children and adolescents (ages 5–21). Responses were summarized using factor analysis of risk mitigation, and their associations with lifetime mental disorders (assessed via structured diagnostic interviews) were identified with linear regression analyses (adjusted for covariates). All analyses used R Project for Statistical Computing for Mac (v.4.0.5).ResultsA two-factor model was the best-fitting solution. Factor 1 (avoidance behaviors) included avoiding groups, indoor settings, and other peoples’ homes; avoidance scores were higher among youth with any anxiety disorder (p = .01). Factor 2 (hygiene behaviors) included using hand sanitizer, washing hands, and maintaining social distance; hygiene scores were lower among youth with ADHD (combined type) (p = .02). Mask wearing was common (90%), did not load on either factor, and was not associated with any mental health disorder.Conclusion and relevanceAlthough most mental disorders examined were not associated with risk mitigation, youth with ADHD characterized by hyperactivity plus inattention may need additional support to consistently engage in risk-mitigation behaviors. Enhancing risk-mitigation strategies among at-risk groups of youth may help reduce COVID-19 infection and transmission.

Mutation burden analysis of six common mental disorders in African Americans by whole genome sequencing.

Mental disorders present a global health concern and have limited treatment options. In today's medical practice, medications such as antidepressants are prescribed not only for depression but also for conditions such as anxiety and attention deficit hyperactivity disorder (ADHD). Therefore, identifying gene targets for specific disorders is important and offers improved precision. In this study, we performed a genetic analysis of six common mental disorders-ADHD, anxiety, depression, delays in mental development, intellectual disabilities (IDs) and speech/language disorder-in the ethnic minority of African Americans (AAs) using whole genome sequencing (WGS). WGS data were generated from blood-derived DNA from 4178 AA individuals, including 1384 patients with the diagnosis of at least one mental disorder. Mutation burden analysis was applied based on rare and deleterious mutations in the AA population between cases and controls, and further analyzed in the context of patients with single mental disorder diagnosis. Certain genes uncovered demonstrated significant P-values in mutation burden analysis. In addition, exclusive recurrences in specific type of disorder were scanned through gene-drug interaction databases to assess for availability of potential medications. We uncovered 15 genes harboring deleterious mutations, including 3-Hydroxy-3-Methylglutaryl-CoA Reductase (HMGCR) and Uronyl 2-Sulfotransferase (UST) for ADHD; Farnesyltransferase, CAAX Box, Beta (FNTB) for anxiety; Xin Actin Binding Repeat Containing 2 (XIRP2), Natriuretic Peptide C (NPPC), Serine/Threonine Kinase 33 (STK33), Pannexin 1 (PANX1) and Neurotensin (NTS) for depression; RUNX Family Transcription Factor 3 (RUNX3), Tachykinin Receptor 1 (TACR1) and NADH:Ubiquinone Oxidoreductase Core Subunit S7 (NDUFS7) for delays in mental development; Hepsin (HPN) for ID and Collagen Type VI Alpha 3 Chain (COL6A3), Damage Specific DNA Binding Protein 1 (DDB1) and NADH:Ubiquinone Oxidoreductase Subunit A11 (NDUFA11) for speech/language disorder. Taken together, we have established critical insights into the development of new precision medicine approaches for mental disorders in AAs.

Spectrum of Nonepileptic Paroxysmal Events in Children from Southern India.

Background Nonepileptic paroxysmal events (NEPEs) present with episodes similar to epileptic seizures but without abnormal electrical discharge on electroencephalogram (EEG). NEPEs are commonly misdiagnosed as epilepsy. Epilepsy is diagnosed on the basis of a detailed history and examination. Emphasis during history to rule out the possibility of NEPE is important. The wrong diagnosis of epilepsy can lead to physical, psychological, and financial harm to the child and the family. Hence, this study was planned. Objective The objective of the study is to evaluate clinical profile, frequency, and spectrum of NEPE in children. Materials and Methods This is a prospective observational study. Patients with NEPE between January 2014 and August 2016 aged < 18 years were enrolled. NEPEs were diagnosed on the basis of history, home video, and EEG recordings. Patients were divided into different categories according to age, specific type of disorder, and system responsible. Patients were followed for their NEPE frequency and outcome. Results A total of 3,660 children presented with paroxysmal events; of them 8% were diagnosed with NEPE. Patients diagnosed with NEPE were classified into three age groups on the basis of their age of onset of symptom; of the total 285 patients, there were 2 neonates (0.7%), 160 infants (56%), and 123 children and adolescents (43.1%). Fifty-eight percent patients were boys. The most common diagnoses were breath-holding spells 113 (39%), followed by syncope 38 (13.3%) and psychogenic nonepileptic seizures 37 (12.9%). About 9 and 5% of patients had concomitant epilepsy and developmental delay, respectively. Conclusions NEPEs account for 8% of paroxysmal events. Most common NEPEs were breath-holding spells among infants and syncope and “psychogenic nonepileptic seizures” in children and adolescents.

Trauma exposure, incident psychiatric disorders, and disorder transitions in a longitudinal population representative sample

Heterotypic continuity, whereby individuals transition from one disorder to another, is common; however, longitudinal studies examining transdiagnostic predictors of heterotypic continuity are lacking. The current study examined whether trauma exposure during childhood (maltreatment) and adulthood (interpersonal and non-interpersonal trauma) is associated with heterotypic continuity in a national sample. Men and women (N = 34,653) who participated in Waves 1 (2001–2002) and 2 (2004–2005) of the National Survey of Alcohol and Related Conditions (NESARC) completed face-to-face interviews about trauma exposure and psychopathology. Risk ratios and population attributable risk proportions (PARPs) quantified the effects of childhood maltreatment and interpersonal and non-interpersonal trauma exposure between Waves 1 and 2 on risk for incident disorders and transitions between specific types of disorders. Twenty percent of respondents reported a Wave 2 incident disorder. Those with any Wave 1 disorder were at increased risk of incident mood (RR range = 1.2–2.1) and anxiety (RR = 1.5–2.7) disorders at Wave 2. Child maltreatment and interpersonal trauma exposure since Wave 1 were associated with roughly 50% of the risk for disorder transitions (RR range = 1.2–2.7); non-interpersonal trauma was associated with 30% of the risk for disorder transitions (RR range = 1.0–1.7). Findings suggest that new onset disorders were common in U.S. adults and trauma exposure explained a large proportion of disorder incidence as well as progression from one disorder to another. Universal prevention efforts that begin early in life, rather than those targeted at specific disorders, would be fruitful for reducing the burden of population mental health and preventing a cascade of mental disorders over the life course.

Aerodynamic Outcomes of Four Common Voice Disorders: Moving Toward Disorder-Specific Assessment

The two goals of the present study were to (1) determine the ability of commonly used aerodynamic voice measures to capture change as a function of known interventions and (2) determine if certain aerodynamic measures demonstrate better responsiveness to change in specific disorder types than others. This is a retrospective, longitudinal, single-blinded, cross-sectional study. Patients (n = 70) with a single voice disorder diagnosis of benign vocal fold lesions (lesions), unilateral vocal fold paralysis (UVFP), primary muscle tension dysphonia (MTD-1), or vocal fold atrophy (atrophy) underwent baseline testing, a single intervention (phonosurgery or voice therapy), and follow-up testing. Common aerodynamic measurements were completed in repeated syllables and an all-voiced sentence. Statistically significant improvements were observed for two outcome measures, average airflow in syllables, and average airflow in the all-voiced sentence. Patients with lesions, UVFP, and MTD-1 improved in average airflow in the all-voiced sentence. Patients with UVFP also improved in airflow in syllables. Average airflow in the all-voiced sentence changed as a function of treatment for the lesion, MTD-1, and UVFP groups, demonstrating a disorder-specific pattern. Laryngeal airway resistance, and estimates of average subglottal pressure did not show significant change. Average airflow in the all-voiced sentence measurements is recommended as a routine voice measure, and further investigation of other aerodynamic measures' sensitivity to change is warranted.

Electric transport through circular graphene quantum dots: Presence of disorder

The electronic states of an electrostatically confined cylindrical graphene quantum dot and the electric transport through this device are studied theoretically within the continuum Dirac-equation approximation and compared with numerical results obtained from a tight-binding lattice description. A spectral gap, which may originate from strain effects, additional adsorbed atoms, or substrate-induced sublattice-symmetry breaking, allows for bound and scattering states. As long as the diameter of the dot is much larger than the lattice constant, the results of the continuum and the lattice model are in very good agreement. We also investigate the influence of a sloping dot-potential step, of on-site disorder along the sample edges, of uncorrelated short-range disorder potentials in the bulk, and of random magnetic fluxes that mimic ripple disorder. The quantum dot's spectral and transport properties depend crucially on the specific type of disorder. In general, the peaks in the density of bound states are broadened but remain sharp only in the case of edge disorder.

Skills Training as an Adjunctive Treatment for Personality Disorders

Personality disorders are usually treated with either psychodynamic or supportive psychotherapy, with psychotropic medication often used as an adjunctive treatment. However, patients with personality disorders pose special treatment issues, because their problems are pervasive and long-standing and they have entrenched deficits in many areas of functioning. In this article, the authors consider the role of skills training in the treatment of personality disorders. They describe a two-pronged approach to the treatment of personality disorders based on a model of deficit compensation. Because skills training has only been investigated in a very limited way in personality disorders, the authors first review research on the use of skills training in Axis I disorders as background for a discussion of ways in which skills training may be applicable to the treatment of Axis II disorders. They describe a number of skills training approaches (social skills training, anger management, and conversational skills) that can be used for a variety of different Axis I disorders. Skills training approaches that are targeted to specific types of disorders (substance use disorders, schizophrenia, anxiety disorders, adolescent problems) are also described. The authors then review what is known about the use of skills training in borderline personality disorder and avoidant personality disorder, and propose skills training approaches that may be useful for patients with paranoid personality disorder and antisocial personality disorder. Case examples are provided to demonstrate how skills training for personality disorders can be applied in clinical practice.

Lost productivity among full-time workers with mental disorders.

BACKGROUND: Few studies have systematically compared the relationship between lost work productivity (work impairment) and mental disorders using population surveys. AIMS: (1) To identify the importance of individual mental disorders and disorder co-occurrences (comorbidity) as predictors of two measures of work impairment over the past month - work loss (number of days unable to perform usual activities) and work cutback (number of days where usual activities were restricted); (2) to examine whether different types of disorder have a greater impact on work impairment in some occupations than others; (3) to determine whether work impairment in those with a disorder is related to treatment seeking. METHOD: Data were based on full-time workers identified by the Australian National Survey of Mental Health and Well-Being, a household survey of mental disorders modeled on the US National Comorbidity Survey. Diagnoses were of one-month DSM-IV affective, anxiety and substance-related disorders. Screening instruments generated likely cases of ICD-10 personality disorders. The association of disorder types and their co-occurrences with work impairment was examined using multivariate linear regression. Odds ratios determined the significance of mental disorder prevalence across occupations, and planned contrasts were used to test for differences in work impairment across occupations within disorder types. The relationship between work impairment and treatment seeking was determined for each broad diagnostic group with t-tests. RESULTS: Depression, generalized anxiety disorder and personality disorders were predictive of work impairment after controlling for impairment due to physical disorders. Among pure and comorbid disorders, affective and comorbid anxiety-affective disorders respectively were associated with the greatest amount of work impairment. For all disorders, stronger associations were obtained for work cutback than for work loss. No relationship was found between type of occupation and the impact of different types of disorder on work impairment. Only 15% of people with any mental disorder had sought help in the past month. For any mental disorder, significantly greater work loss and work cutback was associated with treatment seeking, but comparisons within specific disorder types were not significant. DISCUSSION: A substantial amount of lost productivity due to mental disorders comes from within the full-time working population. The greater impact of mental disorders on work cutback compared to work loss suggests that work cutback provides a more sensitive measure of work impairment in those with mental disorders. Work impairment was based on self-report only. While there is evidence for the reliability of self-assessed work loss days, no reliability or validity studies have been conducted for work cutback days. The low rates of treatment seeking are a major health issue for the workforce, particularly for affective and anxiety disorders, which are important predictors of lost productivity. IMPLICATIONS FOR HEALTH POLICIES AND FURTHER RESEARCH: Future research should investigate the validity of work cutback, given its importance as a measure of lost productivity in people with mental disorders. Employers need to be aware of the extent to which mental disorders affect their employees so that effective work place interventions can take place. Treatment should be targeted at people with affective and anxiety disorders, particularly where they co-occur.

Stochastic One-Dimensional Lorentz Gas on a Lattice

We stud ya one-dimensional stochastic Lorentz gas wher ea light particle moves i na fixed array of nonidentical random scatterers arranged i na lattice. Each scatterer is characterized b ya random transmissionreflection coefficient. We consider the case when the transmission coefficients of the scatterers are independent identically distributed random variables .A symbolic program is presented which generates the exact velocity autocorrelation functio n( VACF) in terms of the moments of the transmission coefficients. The VACF is found for different types of disorder for times up to 20 collision times. We then conside ra specific type of disorder :a two-state Lorentz gas in which two types of scatterers are arranged randomly i na lattice. The na lattice point is occupied b ya scatterer whose transmission coefficient is ' with probability p or '+= with probability 1&p .A perturbation expansion with respect to = is derived. The = 2 term in this expansion shows that the VACF oscillates with time, the period of oscillation being twice the time of flight from one scatterer to its nearest neighbor. The coarse-grained VACF decays for long times like t &32 , which is similar to the decay of the VACF of the random Lorentz gas wit ha single type of scatterer. The perturbation results and the exact one s( found up to 20 collision times) show good agreement.

Racial and Social Class Prevalence of Psychopathology among School-Age Youth in the United States

This article assesses the relative base rates of common forms of youth psychopathology among Whites, African Americans, Hispanics, and rarer minorities and across social classes as defined by parent education levels. A nationwide sample of 1,400 participants aged 5 to 17 years was stratified demographically according to the U.S. census. Standardized teacher observational scales were applied and the most maladjusted youths identified in terms of attention-deficit hyperactive, provocative-aggressive, impulsive-aggressive, oppositional defiant, diffident, and avoidant disorders. Most psychopathology was distributed proportionately across race and class. Patterns displayed by maladjusted White participants were not uniformly common among minorities, with racial or ethnic groups manifesting variable propensity for pathology, depending on level of social advantage and specific type of disorder. Implications are explored as they relate to distinct cultural and social contexts, to popular contemporary perceptions, and to future research and policy development in youth psychopathology.

Anxiety, depression, and perception of early parenting: a meta-analysis

The literature on perceived parental rearing practices in depressed and anxious patients is reviewed by means of a meta-analysis. To this aim, the psychometric and validational properties of questionnaires measuring perceptions of parental rearing styles were investigated, and only studies using satisfactory measures were included in the meta-analysis. Studies were grouped into various categories, such as specific type of disorder, remitted versus nonremitted cases, males versus females, and state versus trait measures of anxiety and depression. It is concluded that various types of phobic disorder were related to a parental rearing style of less Affection and more Control as compared to healthy controls. Findings with regard to depression appeared to be less consistent. Possible explanations for these inconsistencies are offered. Finally, problems with respect to validity of retrospective assessment of parental rearing practices are discussed, and suggestions for future research are provided.

1561 PSYCHIATRIC SEQUELAE OF LOCALIZED CORTICAL INJURY IN CHILDREN

To test the hypothesis that localized cortical damage is associated with specific forms of psychiatric disorder, 54 children with unilateral compound depressed head fractures hospitalized in Great Britain were examined and their parents and teachers interviewed. Children were categorized into four groups by site of dural tear as determined from surgical records. Psychiatric disorder was measured by four symptom scales derived from psychiatrist, parents' and teachers' questionnaires.There were no significant associations between hyperactivity, conduct disorder and other emotional disorders and site of injury or hemisphere. Children with right frontal and left posterior injuries had significantly more severe depressive symptoms than those injured at other sites (F=3.65 p=.02). The contrast between the right frontal-leftposterior and left frontal-right posterior groups remained significant after the effects of social disadvantage, age at injury, age at examination and parental history of psychiatric disorder were controlled in a multiple regression analysis.The general lack of association between locus of injury and form of psychiatric disorder suggests that the effect of localized damage is not marked. The depression results, however, are supported by neurophysiological findings and indicate that damage to a specific site can result in a specific type of disorder.

Defect structure and molecular motion in the four modifications of n -tritriacontane. I. Study of defect structure in the lamellar interfaces using small angle x-ray scattering

The paraffin C33H68 undergoes three solid-solid phase transitions between room temperature and the melting point. The orthorhombic modification (A) stable at low temperatures is followed by two different monoclinic forms (B: 54.5°C &amp;lt; T &amp;lt; 65.5°C; C: 65.5°C &amp;lt; T &amp;lt; 68°C) and by the ``rotator phase'' (D: 68°C &amp;lt; T &amp;lt; Tf=71.8°C). Defect structures as they occur in the three high temperature modifications were determined with the aid of small angle x-ray scattering experiments. A method is applied which permits us to decide about the presence of different types of defects after a measurement of the absolute intensities of the 00l reflections. It was found that each one of the modifications B, C, D is characterized by a specific type of disorder. One observes orientational disorder of the skeletal planes in modification B, a superposition of longitudinal shifts of the chains in modification C, and an additional introduction of intrachain defects in modification D.

Organic Brain Dysfunction and Child Psychiatric Disorder

The total population of 11,865 children of compulsory school age resident on the Isle of Wight was studied to determine the prevalence of epilepsy, cerebral palsy, and other neurological disorders. With the use of reliable methods, children selected from screening of the total population were individually studied by means of parental interviews and questionaries, neurological examination and psychiatric assessment of each child, information from school teachers, and perusal of the records of hospitals and other agencies. The association between organic brain dysfunction and psychiatric disorder was studied by comparing the findings in the children with epilepsy or with lesions above the brain stem (cerebral palsy and similar disorders) with those in (1) a random sample of the general population, (2) children with lesions below the brain stem (for example, muscular dystrophy or paralyses following poliomyelitis), and (3) children with other chronic physical handicaps not involving the nervous system (for example, asthma, heart disease, or diabetes).Psychiatric disorders in children with neuro-epileptic conditions were five times as common as in the general population and three times as common as in children with chronic physical handicaps not involving the brain. It was concluded, on the basis of a study of factors associated with psychiatric disorder, that the high rate of psychiatric disorder in the neuro-epileptic children was due to the presence of organic brain dysfunction rather than just the existence of a physical handicap (though this also played a part). However, organic brain dysfunction was not associated with any specific type of disorder. Within the neuro-epileptic group the neurological features and the type of fit, intellectual/educational factors, and socio-familial factors all interacted in the development of psychiatric disorder.

Preferred Sites for Latent-1 mage Formation

AbstractThe relationship between grain disorder and sites of formation of surface latent-image specks on tabular silver-bromide emulsion grains has been investigated for small latent-image exposures. The technique was to expose the grains, partially develop them to reveal the sites at which developable latent-image specks had been formed, and then to form photolytic silver in the grains to decorate the disorder. It is shown by an electron-micrographic technique that many of the surface latent-image specks are formed where lines of platelets of photolytic silver meet the grain edges. It is concluded that in grains of the above type there may exist at least one specific type of disorder which provides surface sites where nucleation and aggregation of silver occur preferentially at small exposures. A direct demonstration is presented of the competition between surface and internal sites on and within a grain for the electrons produced by exposure.
