    Direct observation in a large-scale randomized trial of parent training in children with autism spectrum disorder and disruptive behavior
    (Elsevier, 2021) Swiezy, Naomi; Smith, Tristam; Johnson, Cindy R.; Bearss, Karen; Lecavalier, Luc; Drill, Rochelle; Warner, Danielle; Deng, Yanhong; Xu, Yunshan; Dziura, James; Handen, Ben; Scahill, Lawrence; Psychiatry, School of Medicine
    A direct observation strategy (Standardized Observation Analogue Procedure, SOAP) was used in a large-scale randomized trial of parent training versus parent education in young children with autism spectrum disorder (ASD) and disruptive behavior. The 16-minute SOAP, modified from an earlier version of this same measure, included parentchild interaction to assess child behavior in a clinical laboratory setting. Despite study entry criteria for all child participants requiring moderate levels of disruptive behavior in this project, 126 of 168 children with complete SOAP data at baseline showed no disruptive behavior on this measure. Although the primary purpose of the study was to determine whether the SOAP could detect differences between the two conditions (i.e.,parent training (PT) and parent education (PE)), baseline observation data was not consistent with parent ratings at baseline or subsequent follow up visits, leaving little room to demonstrate improvement with this observation measure. This and the challenging, time-consuming and resource intensive effort involved in using such a measure in a large randomized scale trial, raises fundamental questions about the validity of the SOAP as an outcome measure in such a study. Further consideration related to the feasibility and practicality of using direct observation as a primary measure in larger scale efforts overall are also discussed.

    Examining Sex-Differentiated Genetic Effects Across Neuropsychiatric and Behavioral Traits
    (Elsevier, 2021-06-15) Martin, Joanna; Khramtsova, Ekaterina A.; Goleva, Slavina B.; Blokland, Gabriëlla A.M.; Traglia, Michela; Walters, Raymond K.; Hübel, Christopher; Coleman, Jonathan R.I.; Breen, Gerome; Børglum, Anders D.; Demontis, Ditte; Grove, Jakob; Werge, Thomas; Bralten, Janita; Bulik, Cynthia M.; Lee, Phil H.; Mathews, Carol A.; Peterson, Roseann E.; Winham, Stacey J.; Wray, Naomi; Edenberg, Howard J.; Guo, Wei; Yao, Yin; Neale, Benjamin M.; Faraone, Stephen V.; Petryshen, Tracey L.; Weiss, Lauren A.; Duncan, Laramie E.; Goldstein, Jill M.; Smoller, Jordan W.; Stranger, Barbara E.; Davis, Lea K.; Biochemistry and Molecular Biology, School of Medicine
    Background: The origin of sex differences in prevalence and presentation of neuropsychiatric and behavioral traits is largely unknown. Given established genetic contributions and correlations, we tested for a sex-differentiated genetic architecture within and between traits. Methods: Using European ancestry genome-wide association summary statistics for 20 neuropsychiatric and behavioral traits, we tested for sex differences in single nucleotide polymorphism (SNP)-based heritability and genetic correlation (rg < 1). For each trait, we computed per-SNP z scores from sex-stratified regression coefficients and identified genes with sex-differentiated effects using a gene-based approach. We calculated correlation coefficients between z scores to test for shared sex-differentiated effects. Finally, we tested for sex differences in across-trait genetic correlations. Results: We observed no consistent sex differences in SNP-based heritability. Between-sex, within-trait genetic correlations were high, although <1 for educational attainment and risk-taking behavior. We identified 4 genes with significant sex-differentiated effects across 3 traits. Several trait pairs shared sex-differentiated effects. The top genes with sex-differentiated effects were enriched for multiple gene sets, including neuron- and synapse-related sets. Most between-trait genetic correlation estimates were not significantly different between sexes, with exceptions (educational attainment and risk-taking behavior). Conclusions: Sex differences in the common autosomal genetic architecture of neuropsychiatric and behavioral phenotypes are small and polygenic and unlikely to fully account for observed sex-differentiated attributes. Larger sample sizes are needed to identify sex-differentiated effects for most traits. For well-powered studies, we identified genes with sex-differentiated effects that were enriched for neuron-related and other biological functions. This work motivates further investigation of genetic and environmental influences on sex differences.

    The Impact of the COVID-19 Pandemic on Behavioral Health in Indiana
    (The Center for Health Policy, 2021-06-01) Kooreman, Harold; Gutta, Jyotsna; Bandali, Elhaam; Greene, Marion S.
    As of January 2021, the Johns Hopkins Coronavirus Resource Center has confirmed more than 20 million SARS-CoV-2 cases and over 350,000 deaths in the United States alone and 100 million cases and more than 2 million deaths globally. As of December 31, 2020, over half a million Hoosiers had tested positive for COVID-19 and more than 8,000 had died as a result of complications from the disease. This report is a review on the impact the COVID-19 pandemic had (and has) on the mental and behavioral health of Hoosiers. Specifically, we reviewed pandemic-related stress on children, parents, and the elderly; substance use, misuse, and overdose deaths; mental health concerns; suicide; domestic violence; and child abuse and neglect. The current report is a summary of findings. It provides a snapshot in time. Data and conclusions were relevant and timely at the time the report was produced.

    Multimodal, longitudinal assessment of intracortical microstimulation
    (Elsevier, 2011) Koivuniemi, Andrew; Wilks, Seth J.; Woolley, Andrew J.; Otto, Kevin J.; Medicine, School of Medicine
    The fundamental obstacle to neuroprostheses based on penetrating microstimulation is the tissue’s response to the device insertion and to the application of the electrical stimulation. Our long-term goal is to develop multichannel microstimulation of central nervous tissue for clinical therapy. The overall objective of this research is to identify the optimal parameters for a chronically implanted microstimulation device. In particular, the work presented here focuses on the effects of repeated stimulation and the reactive tissue response on the efficacy of stimulation-driven behavior. To this end, psychophysical experiments were performed using multichannel cortical implants in the auditory cortex of rats. Further, we investigated the effect of the device–tissue interfacial quality on the psychophysical threshold. Here, we report the effects of cortical depth, days postimplant on the psychophysical threshold of auditory cortical microstimulation, along with correlated impedance spectral changes and post vivo histology. We expect that these data will further enable neuroprosthetic development.
