Patients with systemic lupus erythematosus (SLE) are characterized by increased cardiovascular disease (CVD) risk as well as heightened rates of psychological distress. Since a link between psychological issues and CV morbidity has been previously suggested, the influence of psychological burden on subclinical atherosclerosis in SLE patients was investigated. 71 SLE patients were assessed for the presence of subclinical atherosclerosis-defined either as carotid and/or femoral plaque formation or arterial wall thickening [Intima Media Thickness (IMT) levels > 0.90 mm by Doppler ultrasound]; personality traits, anxiety and depression, sleeping habits and fatigue levels were also evaluated by specific questionnaires including Eysenck Personality Questionnaire Scale, State-Trait Anxiety Inventory (STAI), Zung Depression Scale, Athens Insomnia Scale and Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F). Disease related clinical and laboratory features and traditional risk factors for atherosclerosis were documented. Univariate and multivariate analysis were performed. SLE patients with arterial wall thickening displayed higher STAI anxiety scores (either as a current state or as a personality trait) compared to those without (49.8 ± 5.6 vs. 46.9 ± 5.4, -value: 0.03 and 49.2 ± 4.4 vs. 45.7 ± 6.8, value: 0.009, respectively). In a multivariate model, trait anxiety and extraversion personality scores were found to be independently associated with arterial wall thickening and plaque formation, respectively [OR95%(CI):1.2(1.0-1.5) and 0.7(0.6-1.0), respectively], following adjustment for potential confounders. No other associations were detected. Anxiety and extraversion personality traits have been independently associated with subclinical atherosclerosis in lupus patients, implying psychoneuroimmunological interactions as contributors in SLE related atherosclerosis.

Background: To comprehend the current state of death anxiety among Chinese college students during the COVID-19 pandemic, analyze its influencing factors, and provide recommendations for mitigating death anxiety among these students.

Methods: From March to May 2023, utilizing a cluster sampling method, students from three universities in Changzhou, Jiangsu, were selected as research participants. The investigation employed a general information questionnaire, the PTSD Checklist for DSM-5 (PCL-5), the Chinese Version Templer-Death Anxiety Scale (CT-DAS), and the brief version of the Big Five Inventory (BFI-10).

Background: Although personality trait models have become consolidated as the hegemonic taxonomical models for describing personality and provide excellent capacity for predicting variables of psychological interest (i.e., mental disorders), there are still important gaps in our knowledge about why personality traits predict those variables.

Objectives: The study's aim was to determine co-occurrence of psychopathological symptoms and personality predispositions in post-traumatic stress disorder (PTSD) and its dimensions several months after hospitalisation of patients with severe COVID-19 during the 2nd and 3rd waves of the epidemic.

Methods: At 7-8 months after admission, 138 patients completed the PCL-5 and TIPI questionnaires, as well as the HADS and AIS scales. Correlation analysis and stepwise multiple regression analysis were used in the models.

Understanding the role of personality traits in shaping treatment outcomes is crucial given the multifaceted challenges posed by brain tumors and the significant adverse impact of radiotherapy (RT) on patients' well-being. This study aimed to provide insights into how personality traits affect psychosocial well-being and quality of life during RT in patients with high-grade malignant brain tumors. Personality traits in patients with high-grade glioma were assessed using the Eysenck Personality Questionnaire-Revised (EPQ-R).

Genomic structural equation modeling of reward-related traits: exploring the genetic factor structure and its relationship with psychopathology.

Reward sensitivity has a partial genetic background, and extreme levels may increase vulnerability to psychopathology. This study explores the genetic factor structure underlying reward-related traits and examines how genetic variance links to psychopathology. We modeled GWAS data from ten reward-related traits: risk tolerance (N = 975,353), extraversion (N = 122,886), sensation seeking (N = 132,395), (lack of) premeditation (N = 132,667), (lack of) perseverance (N = 133,517), positive urgency (N = 132,132), negative urgency (N = 132,559), attentional impulsivity (N = 124,739), motor impulsivity (N = 124,104), and nonplanning impulsivity (N = 123,509) to derive their genetic factor structure.
