Perfusion Measures and Outcomes (PERForm) registry: First annual report.

BACKGROUND: The Perfusion Measures and Outcomes (PERForm) registry was established in 2010 to advance cardiopulmonary bypass (CPB) practices and outcomes. The registry is maintained through the Michigan Society of Thoracic and Cardiovascular Surgeons Quality Collaborative and is the official registry of the American Society of Extracorporeal Technology. METHODS: This first annual PERForm registry report summarizes patient characteristics as well as CPB-related practice patterns in adult (≥18 years of age) patients between 2019 and 2022 from 42 participating hospitals. Data from PERForm are probabilistically matched to institutional surgical registry data. Trends in myocardial protection, glucose, anticoagulation, temperature, anemia (hematocrit), and fluid management are summarized. Additionally, trends in equipment (hardware/disposables) utilization and employed patient safety practices are reported. RESULTS: A total of 40,777 adult patients undergoing CPB were matched to institutional surgical registry data from 42 hospitals. Among these patients, 54.9% underwent a CABG procedure, 71.6% were male, and the median (IQR) age was 66.0 [58.0, 73.0] years. Overall, 33.1% of the CPB procedures utilized a roller pump for the arterial pump device, and a perfusion checklist was employed 99.6% of the time. The use of conventional ultrafiltration decreased over the study period (2019 vs. 2022; 27.1% vs. 24.9%) while the median (IQR) last hematocrit on CPB has remained stable [27.0 (24.0, 30.0) vs. 27.0 (24.0, 30.0)]. Pump sucker termination before protamine administration increased over the study period: (54.8% vs. 75.9%). CONCLUSION: Few robust clinical registries exist to collect data regarding the practice of CPB. Although data submitted to the PERForm registry demonstrate overall compliance with published perfusion evidence-based guidelines, noted opportunities to advance patient safety and outcomes remain.

Dark Triad Psychopathy Outperforms Self-Control in Predicting Antisocial Outcomes: A Structural Equation Modeling Approach.

Dark Triad traits and self-control are considered viable causal precursors to antisocial and criminal outcomes in youth. The purpose of the present study is to concurrently compare how Dark Triad traits and self-control differ in terms of predicting self-reported juvenile delinquency, CD symptoms, proactive overt aggression, and crime seriousness. The sample consisted of 567 (M = 15.91 years, SD = 0.99 years, age range = 14-18 years) Southern European youth from Portugal. Structural-equation-modelling procedures revealed that the psychopathy factor of Dark Triad traits presented the strongest significant hypothetical causal associations with the antisocial/criminal outcomes, followed by self-control. Machiavellianism and narcissism presented the lowest causal associations. Our findings indicate that psychopathy, as operationalized in the Dark Triad, concurrently surpasses self-control and the remaining factors of the Dark Triad in terms of predicting antisocial/criminal outcomes in youth. This suggests that behavioral disinhibition, or a core incapacity to regulate one's conduct, is central for understanding delinquency and externalizing psychopathology. Comparatively, the interpersonal component of dark personality features, such as Machiavellianism and narcissism, are secondary for understanding crime.

Predictors of Skeptical Responses to Disclosures of Childhood Sexual Abuse.

Victims of Childhood Sexual Abuse (CSA) may be met with skeptical responses when they disclose their experience. The fear of such a response means that most victims delay telling anyone about the abuse. The aim of this study was to explore how contextual factors of abuse such as victim gender and age, perpetrator gender, and victim-perpetrator relationship affect a response to CSA. Further, we explored what personality traits may predict a skeptical response. An online questionnaire with 357 undergraduate students asked participants to read a vignette describing CSA, and to indicate the extent to which they believed the vignette, whether they blamed the victim or perpetrator, and what punishment they would recommend for the perpetrator. Results indicated that older victims were less likely to be believed and more likely to be blamed than younger victims. Further, we found more blame was placed on a perpetrator of intrafamilial abuse compared with extrafamilial abuse, but only if the perpetrator was male. Female perpetrators were punished less harshly than male perpetrators, but female intrafamilal perpetrators received harsher punishment than female extrafamilial perpetrators. No such effect was found for male perpetrators. Openness to Experience was associated with a more supportive response to CSA, as was Agreeableness. Implications and future directions are discussed.

The Association between Psychopathy and Influencing Others to Use Substances.

Background: Although a large body of research has examined the impact of peer influence on substance use, little is known about the psychology of who influences others to use substances and why. The Dark Triad is a set of personality traits that may inform the characteristics of people who influence others to use substances.Objective: The aim of the present two studies was to examine potential associations between Dark Triad personality traits, especially psychopathy, and influencing others to use substances.Methods: Two samples of 162 and 161 Mechanical Turk workers were recruited for Study 1 to complete an online survey that assessed Dark Triad traits, history of influencing others to use substances, and motivations for doing so. Similarly, 303 Mechanical Turk workers were recruited for Study 2 to complete an online survey that assessed personal substance use as well as psychopathy levels of participants' closest friends.Results: Study 1 found that individuals high in psychopathy were more likely to have provided illegal substances to others and indicated a willingness to do so in the future. Study 2 found that participants reported a higher likelihood of using substances if they indicated that their best friend was high in psychopathy and had themselves used substances in the past.Conclusions: Taken together, these findings suggest that psychopathy has a unique association with influencing others to use substances. These findings have implications for intervention targets.

Aggression as a trait: the Dark Tetrad alternative.

Aggression is often construed as a unitary trait fully captured by the Buss-Perry Aggression Questionnaire (BPAQ). Our review of the literature questions that assumption in several respects. Instead of a top-down approach, we argue for a bottom-up conception based on the Dark Tetrad of personality, that is, narcissism, Machiavellianism, psychopathy, and sadism. We highlight research showing that each member of the tetrad responds to different provocations. We conclude that the unitary trait conception of aggression has yielded more confusion than understanding. The term aggression should be reserved for outcomes, with many possible trait×situation predictors. Future research should continue the investigation of moderators as well as cognitive mediators to clarify the triggering of aggression in the individual tetrad members.
