J Autism Dev Disord 2021 Sep 7. Epub 2021 Sep 7.

Division of Child and Adolescent Psychiatry, Cincinnati Children's Hospital Medical Center, 3333 Burnet Ave, MLC 4002, Cincinnati, OH, 45229, USA.

Recent decades have been marked by a wave drug treatment research in autism spectrum disorder (ASD). This work has resulted in improved ability to treat commonly occurring behavioral challenges associated with ASD including most prominently irritability marked by aggression, self-injurious behavior, and severe tantrums. While treatment of interfering behavior has progressed in our field, there remain several areas of unmet medical need including most prominently a lack of any approved drug therapies for the core, defining symptoms of autism.

The Dark Triad of Personality: Is Psychopathy a Good Predictor of Workplace Stress?

Mater Sociomed 2021 Jun;33(2):100-104

Department of Psychology, Faculty of Philosophy, University of Sarajevo, Sarajevo, Bosnia and Herzegovina.

Background: Psychopathy as an antisocial characteristic of an individual is characterized by a lack of empathy, guilt, inability to control impulsive behavior, irresponsibility, irritability and aggressive behavior. Because of the traits that underlie this factor, we hypothesized that psychopaths would experience more stress in the work environment. Stress, in this article, is operationalized within Karasek's model of stress which consider that contextual variables (excessive demands on work, lack of social support, and lack of control at work) are responsible for experiencing stress at the workplace.

Neurobiological correlates of antisociality across adolescence and young adulthood: a multi-sample, multi-method study.

Psychol Med 2021 Aug 27:1-16. Epub 2021 Aug 27.

Child and Adolescent Psychiatry and Psychosocial Care, Amsterdam UMC, Vrije Universiteit Amsterdam, de Boelelaan 1117, Amsterdam, the Netherlands.

Background: Antisociality across adolescence and young adulthood puts individuals at high risk of developing a variety of problems. Prior research has linked antisociality to autonomic nervous system and endocrinological functioning. However, there is large heterogeneity in antisocial behaviors, and these neurobiological measures are rarely studied conjointly, limited to small specific studies with narrow age ranges, and yield mixed findings due to the type of behavior examined.

Biochemical and Clinical Effects of Vitamin E Supplementation in Hungarian Smith-Lemli-Opitz Syndrome Patients.

Biomolecules 2021 08 17;11(8). Epub 2021 Aug 17.

Division of Clinical Genetics, Department of Laboratory Medicine, Faculty of Medicine, University of Debrecen, 4032 Debrecen, Hungary.

Smith-Lemli-Opitz syndrome (SLOS) is a severe monogenic disorder resulting in low cholesterol and high 7-dehydrocholesterol (7-DHC) levels. 7-DHC-derived oxysterols likely contribute to disease pathophysiology, and thus antioxidant treatment might be beneficial because of high oxidative stress. In a three-year prospective study, we investigated the effects of vitamin E supplementation in six SLOS patients already receiving dietary cholesterol treatment. Read More

Icahn School of Medicine at Mount Sinai, New York, and New York City Health + Hospitals/Elmhurst, New York.

Child and adolescent psychiatrists have company as they wrestle with clinical decision making regarding when it is appropriate to prescribe an antipsychotic. Pediatricians face a similar challenge in trying to determine under what circumstances to prescribe an antibiotic. Both classes of medications are powerful and can be lifesaving, but they are not without the risk of associated adverse events and cumulative exposure. Read More

Dynamics of data-driven microstates in bipolar disorder.

J Psychiatr Res 2021 09 16;141:370-377. Epub 2021 Jul 16.

Department of Population Health Sciences, 610 Walnut Street, 707 WARF Building, University of Wisconsin, Madison, WI, 53706, USA; Department of Mathematics, Van Vleck Hall, 480 Lincoln Drive, University of Wisconsin, Madison, WI, 53706, USA. Electronic address:

Many of the existing models of mood in bipolar disorder can largely be divided into two camps, tracking mood as either a discrete or continuous variable. Both groups rely upon certain assumptions, with most considering only aggregate scores on clinical instruments. In this study, we propose a novel framework that combines elements from both discrete and continuous mood models, using a machine learning pipeline to detect subtle patterns across individuals.

The Irritable and Oppositional Dimensions of Oppositional Defiant Disorder: Integral Factors in the Explanation of Affective and Behavioral Psychopathology.

Child Adolesc Psychiatr Clin N Am 2021 07;30(3):637-647

Department of Psychological Sciences, University of Connecticut, 406 Babbidge Road, Storrs, CT 06269, USA.

Oppositional defiant disorder includes distinct but inseparable dimensions of chronic irritability and oppositional behavior. The dimensions have been identified in early childhood to adulthood, and show discriminant associations with internalizing and externalizing psychopathology. The introduction of disruptive mood dysregulation disorders and the requirements that it take precedence over oppositional defiant disorder diagnostically are not supported by evidence and introduce confusion about the structure and linkages of irritability and oppositional behavior, and obscure the importance of the behavioral dimension in explaining and predicting poor outcomes.
