The Effects of Including a Callous Unemotional Specifier for the Diagnosis of Conduct Disorder

“With Significant Callous-Unemotional Traits” has been proposed as a specifier for Conduct Disorder (CD) in the upcoming revision of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). The impact of this specifier on children diagnosed with CD should be considered

Reward Dysregulation and Mood Symptoms in an Adolescent Outpatient Sample

Research on bipolar spectrum disorders (BPSD) in adolescence has burgeoned in the last decade, but continued work is needed to identify endophenotypic markers associated with illness onset and course. The present study examined reward dysregulation – measured via the behavioral activation system (BAS) – as one putative marker of BPSD in adolescence. A diverse group of 425 outpatient adolescents between 11–17 years of age (52% male) completed the Behavioral Inhibition and Activation Scale (BIS-BAS) scale to measure reward dysregulation. Semi-structured interviews determined diagnoses and severity of mood symptoms. Parent-reported BAS was associated with increased symptoms of mania, and parent and adolescent-reported BAS were associated with symptoms of depression. Parent-reported BIS scores were associated with increased symptoms of mania. Results held independent of diagnostic status. Furthermore, parent BIS/BAS reports were stronger predictors for manic symptoms compared to adolescent-reports. Results extend work in adults with BPSD, suggesting a transdiagnostic association between reward dysregulation and mood symptom severity in adolescence

Helical Conformation of the SEVI Precursor Peptide PAP248-286, a Dramatic Enhancer of HIV Infectivity, Promotes Lipid Aggregation and Fusion

AbstractIn previous in vivo studies, amyloid fibers formed from a peptide ubiquitous in human seminal fluid (semen-derived enhancer of viral infection (SEVI)) were found to dramatically enhance the infectivity of the HIV virus (3–5 orders of magnitude by some measures). To complement those studies, we performed in vitro assays of PAP248-286, the most active precursor to SEVI, and other polycationic polymers to investigate the physical mechanisms by which the PAP248-286 promotes the interaction with lipid bilayers. At acidic (but not at neutral) pH, freshly dissolved PAP248-286 catalyzes the formation of large lipid flocculates in a variety of membrane compositions, which may be linked to the promotion of convective transport in the vaginal environment rather than transport by a random Brownian motion. Furthermore, PAP248-286 is itself fusiogenic and weakens the integrity of the membrane in such a way that may promote fusion by the HIV gp41 protein. An α-helical conformation of PAP248-286, lying parallel to the membrane surface, is implicated in promoting bridging interactions between membranes by the screening of the electrostatic repulsion that occurs when two membranes are brought into close contact. This suggests that nonspecific binding of monomeric or small oligomeric forms of SEVI in a helical conformation to lipid membranes may be an additional mechanism by which SEVI enhances the infectivity of the HIV virus

Distinguishing primary and secondary variants of callous-unemotional traits among adolescents in a clinic-referred sample.

The current study used model-based cluster analyses to determine if there are two distinct variants of adolescents (ages 11 - 18) high on callous-unemotional (CU) traits that differ on their level of anxiety and history of trauma. The sample (n = 272) consisted of clinic-referred youths who were primarily African-American (90%) and from low income families. Consistent with hypotheses, three clusters emerged, including a group low on CU traits, as well as two groups high on CU traits that differed in their level of anxiety and past trauma. Consistent with past research on incarcerated adults and adolescents, the group high on anxiety (i.e., secondary variant) was more likely to have histories of abuse and had higher levels of impulsivity, externalizing behaviors, aggression, and behavioral activation. In contrast, the group low on anxiety (i.e., primary variant) scored lower on a measure of behavioral inhibition. On measures of impulsivity and externalizing behavior, the higher scores for the secondary cluster only were found for self-report measures, not on parent-report measures. Youths in the primary cluster also were perceived as less credible reporters than youth in the secondary or cluster low on CU traits. These reporter and credibility differences suggest that adolescents within the primary variant may underreport their level of behavioral disturbance, which has important assessment implications

The collateral impact of COVID-19 emergency on neonatal intensive care units and family-centered care: Challenges and opportunities

The ongoing Coronavirus disease 2019 (COVID-19) pandemic is disrupting most specialized healthcare services worldwide, including those for high-risk newborns and their families. Due to the risk of contagion, critically ill infants, relatives and professionals attending neonatal intensive care units (NICUs) are undergoing a profound remodeling of the organization and quality care. In particular, mitigation strategies adopted to combact the COVID-19 pandemic may hinder the implementation of family-centered care within the NICU. This may put newborns at risk for several adverse effects, e.g., less weight gain, more nosocomial infections, increased length of NICU stay as well as long-term worse cognitive, emotional, and social development. This article aims to contribute to deepening the knowledge on the psychological impact of the COVID-19 on parents and NICU staff members based on empirical data from the literature. We also provided evidence-based indications on how to safely empower families and support NICU staffs facing such a threatening emergency, while preserving the crucial role of family-centered developmental care practices

Working with bipolar disorder during the covid-19 pandemic: Both crisis and opportunity

© 2020, WikiJournal User Group. All rights reserved. Beyond public health and economic costs, the COVID-19 pandemic adds strain, disrupts daily routines, and com-plicates mental health and medical service delivery for those with mental health and medical conditions. Bipolar disorder can increase vulnerability to infection; it can also enhance stress, complicate treatment, and heighten interpersonal stigma. Yet there are successes when people proactively improve social connections, prioritize self-care, and learn to use mobile and telehealth effectively

Development and Initial Validation of the in-Session Patient Affective Reactions Questionnaire (SPARQ) and the Rift In-Session Questionnaire (RISQ)

This article discusses the development and preliminary validation of a self-report inventory of the patient’s perception of, and affective reaction to, their therapist during a psychotherapy session. First, we wrote a pool of 131 items, reviewed them based on subject matter experts’ review, and then collected validation data from a clinical sample of adult patients in individual therapy (N = 701). We used exploratory factor analysis and item response theory graded response models to select items, confirmatory factor analysis (CFA) to test the factor structure, and k-fold cross-validation to verify model robustness. Multi-group CFA examined measurement invariance across patients with different diagnoses (unipolar depression, bipolar disorder, and neither of these). Three factors produced short scales retaining the strongest items. The in-Session Patient Affective Reactions Questionnaire (SPARQ) has a two-factor structure, yielding a four-item Negative affect scale and a four-item Positive affect scale. The Relationship In-Session Questionnaire (RISQ) is composed of four items from the third factor with dichotomized responses. Both scales showed excellent psychometric properties and evidence of metric invariance across the three diagnostic groups: unipolar depression, bipolar disorder, and neither of these. The SPARQ and the RISQ scale can be used in clinical or research settings, with particular value for capturing the patient’s perspectives about their therapist and session-level emotional processes

Clinicians’ Emotional Reactions toward Patients with Depressive Symptoms in Mood Disorders: A Narrative Scoping Review of Empirical Research

The purpose of this article is to narratively review the empirical literature on clinicians’ emotional, cognitive, and behavioral responses (i.e., countertransference) to depressive and other symptoms of patients with mood disorders. Therapist subjective responses (countertransference) can negatively affect both diagnostic and therapeutic processes, especially when they are not recognized and managed promptly. However, at the same time, countertransference recognition, processing, and management can help inform the diagnostic process and improve the therapy process and outcome. In the last couple of decades, the number of studies that empirically explore countertransference toward mood disordered patients, as well as its relationship with various characteristics of both patients and treatment, has increased. Current evidence suggests that patients with depression tend to elicit more positive feelings among clinicians than patients with other severe mental disorders such as borderline personality disorder or schizophrenia. Furthermore, it documents the existence of associations between patients’ severity of depressive symptoms and clinicians’ subjective reactions, although the results regarding which specific countertransference patterns are evoked in relation to the different phases of the treatment are not entirely consistent. Lastly, growing evidence suggests the presence of clinicians’ specific emotional reactions towards patients with suicidal ideation and behavior

How should we screen for depression following a natural disaster? An ROC approach to post-disaster screening in adolescents and adults

The present study’s aim was to provide the foundation for an efficient, empirically based protocol for depression screening following a natural disaster. Utilizing a Receiver Operating Characteristic (ROC) analytic approach, the study tested a) what specific disaster-related stressors (i.e., property damage, loss of basic services) and individual-related constructs (i.e., PTSD symptoms, trauma history, social support) conveyed the greatest risk for post-natural disaster depression, b) specific cutoff scores across these measures, and c) whether the significance or cutoff scores for each construct varied between adolescents and adults
