Quality of Life Among Breast Cancer Patients in Mures County, Romania: A Cross-Sectional Study.

Background and aim Psychiatric pathology does not always start on its own but may be conditioned or triggered by a comorbidity with a high impact on the human psyche. When there are comorbidities, psychiatric pathology can occur due to the high diagnostic burden. Our study aims to find out if there is a correlation between the diagnosis of breast cancer and its severity, and psychiatric symptoms such as depressive mood, atypical anxiety, or even autolytic ideation that directly influence the quality of life of patients. Materials and methods The study is a prospective, cross-sectional, single-center study carried out between December 2023 and June 2024 at the Mureș County Clinical Hospital in Romania. The sample population had to be at least 18 years old and had to be diagnosed with breast cancer recently. We applied two tests, WHODAS 2 (World Health Organization's Disability Assessment Schedule 2.0) and level 1 (level 1 of cross-sectional measurements of symptoms), to be able to measure and aid assessment of mental health domains that are important across psychiatric diagnoses and also the degree of disability triggered by breast cancer. The statistical analysis included descriptive statistics and interferential statistics. Statistical tests, such as Shapiro-Wilk, Kruskal-Wallis, and Mann-Whitney U tests with Bonferroni correction tests, were used. The p-value was set to 0.05 with a confidence interval (CI) of 95%. Results The study included 120 women diagnosed with breast cancer, with a mean age of 56.64 ± 9.46 years. Regarding the severity of the diagnosis, 44 women (36.66%) had non-invasive cancer, 58 (48.33%) had invasive cancer, and 18 (15%) had metastases. There was a statistically significant difference between three of the five selected level 1 domains across cancer types. The WHODAS 2.0 disability scores showed a significant difference between groups (p < 0.001). Subjects with non-invasive cancer had the lowest WHODAS 2.0 score, followed by the invasive group, while metastases had the highest score. Conclusions Following the application of the two tests, level 1 and WHODAS 2.0, to our group of subjects, statistically significant differences were observed between the three categories of subjects. The degree of disability and the occurrence of psychological symptoms differed according to the severity of breast cancer. Adapting to the status of an oncological patient entails multiple changes from a psycho-emotional, social, occupational, and professional point of view. Although the most recent medications prolong survival, a holistic approach that considers psychological aspects can improve patients' long-term results.

Cybernetic Principles in Psychophysiology: Their Significance and Conclusions for Palliative Care.

Palliative care is dedicated to terminally ill patients with advanced disease, regardless of diagnosis, under the overarching premise of optimizing quality of life. This narrative review examines the extent to which principles of cybernetics and psychophysiology underlie this approach. Psychophysiology researches the physiological equivalents of psychological states and traits such as activation and individual reactivity, the interoception and the personal characteristics. Cybernetics specifies these principles, which are possible by understanding terms such as "psychophysiology" or "cybernetics" or "self-organization/autopoiesis". The meaning of these terms for palliative care can also be elucidated in relation to the terms "biofeedback", "consciousness", "pain", and "anxiety". The common themes of cybernetics and psychophysiology are environment, subjectivity, personality characteristics, the difference between time scale separation in cybernetic systems, and real-time procedures in environment and rhythm. These lead to special therapies based on psychophysiology, such as consciousness training. The concepts of quality of life, causality, the biopsychosocial model, therapy, and autonomy are examined as palliative care concepts. The equivalents can be described from the perspective of cybernetics. For some palliative care-related terms, cybernetic thinking is already present (quality of life, autonomy, symptom control), while for others, it is not (biopsychosocial). Cybernetic terms (complexity, stability, identity, rhythm) are still used to a lesser extent in palliative care. Terms like genetic basis are common in cybernetics and psychophysiology to explain the identity of the subject in transition. Identity, on the other hand, is the basis of the concept of dignity in palliative care. Psychophysiology investigates disturbances like pain and psychological illnesses, which are also present in palliative care. Psychophysiology, cybernetics, and palliative care have subjectivity and resources in common. Therapies based on cybernetic principles of psychophysiology can also be used for symptom control in palliative care in the oncology setting.

Factors associated with medical students' career choice in different specialties: a multiple cross-sectional questionnaire study at a German medical school.

BACKGROUND: Given the shortage and unequal distribution of physicians across specialties, we aimed to evaluate factors associated with medical students' career choices, including background, personality traits, educational experience, personal interests, lifestyle considerations, and the awareness of work requirements. METHODS: We conducted multiple cross-sectional surveys of students; a 159-item online questionnaire was designed and students from three different stages of the six-year medical degree course (outset, clinical phase, and on graduation) were invited to complete the survey. Data were collected between May 2021 and April 2023. RESULTS: The questionnaire was sent to 1406 students, of whom 683 replied (49%); 481 respondents were female (70%). The top specialty choices across the respondents were internal medicine, surgery, and general practice, with anaesthesiology, paediatric and adolescent medicine (ranging 11-15%), and obstetrics and gynaecology also receiving interest, with 6% undecided. In particular, female students lost interest in surgery during the course of study in favour of the other options. The choice of general practice was associated with more vocational training, prior positive experiences with the specialty, and lower grades in the university entry examination. Clinical clerkships in a specific (freely chosen) specialty aligned with career choice, while the final practical year did not have an impact on career decision-making. All students highly desired regulated working hours and work-life-balance; however, students choosing surgery rated these items as less important. Willingness to work in a hospital environment was highly associated with choosing anaesthesiology and surgery, whereas rural areas and practices were associated with general practice. Higher scores at agreeableness were associated with choosing paediatric and adolescent medicine by more female students, whereas lower neuroticism values were associated with the choice of anaesthesiology. CONCLUSIONS: The results highlight the intricate nature of decision-making and shed light on various aspects that contribute to the process of selecting a specialty. By identifying and addressing influencing factors, we can develop targeted interventions and policies to enhance diversity and distribution across medical specialisations and to aim for high-quality and equitable healthcare that matches the specific needs of both individuals and the population as a whole.

Breast Cancer and Its Impact on Individual Personality Through a Dimensional Perspective: A Literature Review.

Psychiatric pathology stands out in contemporary society not only as independent but also through its association with other medical comorbidities such as neoplastic diseases. Specialized literature confirms over time the coexistence of these diseases. There is a tendency to develop various psychiatric manifestations such as mood disorders and somatoform disorders, as well as decompensation of underlying existing psychiatric pathologies (anxiety disorders and psychotic disorders) or personality disorders (a good example is the exacerbation of anxiety in obsessive-compulsive personality disorder). Breast cancer, like any disabling disease, affects the person's psyche and behaviors as a whole. It is scientifically proven that mental balance influences the quality of life of patients and also the evolution and prognosis of the disease, psychological processes being able to modulate the activity of the tumor process. It is necessary to expand clinical practice and research beyond the simple evaluation of symptoms, and the goal of treatment should not only be to reduce symptoms but also to improve in terms of both physically and mentally the quality of life of cancer patients.

Better understanding of c-reactive protein and leukocytes in psychiatric inpatients with affective disorders: A biopsychosocial approach.

BACKGROUND: Affective disorders (AD) have been linked to inflammatory processes, although the underlying mechanisms of this relationship are still not fully elucidated. It is hypothesized that demographic, somatic, lifestyle, and personality variables predict inflammatory parameters in AD. AIM: To identify biopsychosocial factors contributing to inflammation in AD measured with two parameters, C-reactive protein (CRP) and leukocytes. METHODS: This observational study investigated 186 hospital inpatients diagnosed with AD using demographic parameters, serum inflammatory markers, somatic variables, psychological questionnaires, and lifestyle parameters. Hierarchical regression analyses were used to predict inflammatory markers from demographic, somatic, lifestyle, and personality variables. RESULTS: Analyses showed that 33.8% of the variance of CRP was explained by body mass index and other somatic medication (e.g. anti-diabetics), age and education, and age of affective disorder diagnosis. For leukocytes, 20.1% of the variance was explained by smoking, diet, metabolic syndrome (MetS), and anti-inflammatory medication (e.g. non-steroidal anti-inflammatory drugs). Other psychiatric or behavioural variables did not reach significance. CONCLUSION: Metabolic components seem important, with mounting evidence for a metabolic affective disorder subtype. Lifestyle modifications and psychoeducation should be employed to prevent or treat MetS in AD.

Death anxiety among caregivers of patients with advanced cancer: a cross-sectional survey.

PURPOSE: This study aimed to investigate death anxiety (DA) in caregivers of patients with advanced cancer and identify associated factors in the context of Chinese culture. METHODS: Caregivers (N = 588) of advanced cancer patients in a tertiary cancer hospital completed anonymous questionnaire surveys. Measures included the Chinese version of the Templer Death Anxiety Scale (C-T-DAS), the Quality-of-Life Scale, the State-Trait Anxiety Scale, and the Social Support Rating Scale. Data were analyzed in SPSS (IBM Corp, Armonk, NY, USA) using descriptive statistics, Pearson's correlation test, and linear regression. RESULTS: Respondents returned 588 (93.03%) of the 632 questionnaires. The total C-T-DAS score was 7.92 ± 2.68 points. The top-scoring dimension was "Stress and pain" (3.19 ± 1.29 points), followed by "Emotion" (2.28 ± 1.31 points) and "Cognition" (1.40 ± 0.94 points). In contrast, the lowest-scoring dimension was "Time" (1.06 ± 0.77 points). Factors associated with DA (R2 = 0.274, F = 13.348, p < 0.001) included quality of life (QoL), trait anxious personality, social support, caregiver length of care, caregiver gender, and patients' level of activities of daily living (ADL). CONCLUSIONS: Our results demonstrated high levels of DA in caregivers of patients with advanced cancer. Generally, female caregivers and those with low social support had high DA. Caregivers caring for patients with low ADL levels or with a low QoL and trait anxious personality reported high DA. Certain associated factors help to reduce caregivers DA. Social interventions are recommended to improve the end-of-life transition and trait anxious personality as well as quality of life for caregivers.

Quality of life and death anxiety among caregivers of patients with advanced cancer: the mediating effect of trait anxious personality and the moderating effect of social support.

PURPOSE: To explore the mediating role of trait anxious personality in the association between quality of life (QoL) and death anxiety (DA), as well as to test the moderating effect of social support in the mediation model. METHODS: The Death Anxiety Scale, Quality of Life Scale, State-Trait Anxiety Scale, and Social Support Rating Scale were used to measure 588 family caregivers of advanced cancer patients. We then constructed a moderated mediation model. RESULTS: The presence of QoL was negatively associated with DA (ß = - 0.67, p < 0.01). Trait anxious personality partially mediated the relationship between QoL and DA (indirect effect ß = - 0.08, p < 0.01). Social support moderated both the antecedent and subsequent segments of the mediating paths of "QoL → trait anxious personality → DA" and the direct relationship between QoL and DA. Among caregivers with a low level of social support, the mediating effect coefficient of trait anxious personality was higher at 0.25 (95% confidence interval (CI): 0.059-0.182), in contrast to caregivers with a high level of social support, where the mediating effect coefficient of trait anxious personality was 0.11 (95% CI: 0.029-0.072). CONCLUSION: QoL is directly associated with an increased risk of DA and indirectly related to DA by increasing the risk of trait anxious personality among caregivers. Social support can moderate the mediating effect of trait anxious personality and the relationship between QoL and DA. The intervention strategy for preventing DA among caregivers who have encountered QoL reduction should focus on reducing trait anxious personality and social support.

The Association Between Personality Traits and Health-Related Quality of Life and the Mediating Role of Smoking: Nationwide Cross-Sectional Study.

Background: There are positive and negative correlations in different directions between smoking, personality traits, and health-related quality of life (HRQOL), where smoking may mask the pathway between personality traits and HRQOL. Understanding the masking pathway of smoking between personality traits and HRQOL can elucidate the mechanisms of smoking's psychosocial effects and provide new ideas for developing tobacco control strategies. Objective: The purpose of this study was to investigate the correlation between Big Five personality traits and HRQOL and whether smoking mediates the relationship between them. Methods: This was a cross-sectional study using data from 21,916 respondents from the 2022 Psychology and Behavior Investigation of Chinese Residents survey. Linear regression models were used to analyze the correlations between smoking, Big Five personality traits, and HRQOL while controlling for potential confounders. The mediating role of smoking on the association between Big Five Personality traits and HRQOL was analyzed using the Sobel-Goodman mediation test. Results: Extraversion (ß=.001; P=.04), agreeableness (ß=.003; P<.001), and neuroticism (ß=.003; P<.001) were positively correlated with HRQOL, whereas openness was negatively correlated with HRQOL (ß=-.001; P=.003). Smoking was associated with a decrease in HRQOL and mediated the positive effect of HRQOL on extraversion (z=-2.482; P=.004), agreeableness (z=-2.264; P=.02), and neuroticism (z=-3.230; P=.001). Subgroup analyses further showed that smoking mediated the effect of neuroticism on HRQOL in the population with chronic illnesses (z=-2.724; P=.006), and in the population without chronic illnesses, smoking contributed to the effect of HRQOL on extraversion (z=-2.299; P=.02), agreeableness (z=-2.382; P=.02), and neuroticism (z=-2.213; P=.03). Conclusions: This study provided evidence that there is a correlation between personality traits and HRQOL. It also found that smoking plays a role in mediating the connection between personality traits and HRQOL. The development of future tobacco control strategies should consider the unique traits of each individual's personality, highlighting the significance of extraversion, agreeableness, and neuroticism.

Personality traits and measures of neuropsychiatric symptoms.

OBJECTIVES: Changes in personality and behavioral symptoms are a core clinical criterion for the diagnosis of dementia. This study examines the association between caregiver-rated personality traits and multiple measures of neuropsychiatric symptoms. METHOD: Caregivers of individuals with dementia (N = 191) or cancer (N = 137) provided premorbid and concurrent personality trait ratings using the Big Five Inventory-2. Caregivers also completed the Mild Behavioral Impairment Checklist, Neuropsychiatric Inventory Questionnaire, and Revised Memory and Behavior Problems Checklist. RESULTS: In the combined sample, high concurrent neuroticism was associated with emotional dysregulation (r = 0.51), low agreeableness with impulse dyscontrol (r=-0.40), and low conscientiousness with decreased motivation (r=-0.42). Associations were similar across neuropsychiatric symptom scales, similar across cancer and dementia, but stronger with concurrent than premorbid personality ratings, and stronger for the individuals with mild than moderate-severe dementia. CONCLUSION: Personality was associated with neuropsychiatric symptoms, including with the measure for mild behavioral impairment. Personality had stronger associations when concurrently assessed, indicating that personality traits co-develop with neuropsychiatric symptoms. The associations were similar across cancer and dementia, suggesting transdiagnostic processes not limited to dementia. Neuropsychiatric symptoms are partly an expression of personality; accounting for personality traits could help with diagnosis and disease monitoring, tailoring interventions, and fostering person-centered care.

HINT1 Gene Polymorphisms, Smoking Behaviour, and Personality Traits: A Haplotype Case-Control Study.

The factors influencing the development and maintenance of nicotine dependence are numerous and complex. Recent studies indicate that smokers exhibit distinct genetic predispositions to nicotine dependence. We aimed to analyse (1) the association between rs2551038 and cigarette smoking, (2) the association of between the rs3864236-rs2526303-rs2551038 haplotype and cigarette smoking, and (3) the personality traits measured by the NEO Five-Factor Inventory in cigarette users and never-smokers. No significant differences were present in the frequency of rs2551038 genotypes and alleles in the studied cigarette users compared to the control group. Cigarette users, compared to the control group, had higher scores on the NEO-FFI Extraversion scale (p = 0.0011), and lower scores were obtained by the cigarette users for the NEO-FFI Openness (p = 0.0060), Agreeability (p ≤ 0.000), and Conscientiousness (p ≤ 0.000) scales. There was a significant positive Pearson's linear correlation between the age and the Fagestrom test (r = 0.346; p < 0.0001) and the NEO-FFI Openness scale (r = 0.180; p < 0.0001) in the group of cigarette users. We observed significant linkage disequilibrium between rs2526303 and rs3864236 (D' = 0.3581; p < 2.2204 × 10-16) and between rs2526303 and rs2551038 (D' = 0.9993; p < 2.2204 × 10-16) in the tested sample. The sex-stratified haplotype analysis revealed that in the group of male never-smokers, the GTC haplotype was significantly more frequent than in the group of cigarette users (38% vs. 22%; p = 0.0039). The presented study reveals significant differences in personality trait scores between cases and controls. Moreover, the sex-stratified analysis showed significant differences in haplotype distribution. These results underscore the interplay between genetic predisposition, sex, and personality in nicotine-using individuals.

Validity of the Health Personality Assessment among rectal cancer survivors in Serbia.

Understanding health personality traits in rectal cancer survivors could help to optimize recovery and coping mechanisms. The objective of this study was to evaluate psychometric properties of the Health Personality Assessment in Serbian language among rectal cancer survivors. A cross-sectional study was carried out from June to December 2022. The study sample consisted of 76 people who underwent the open lower anterior resection for rectal carcinoma at the Clinic for Digestive Surgery and the Clinic for Emergency Surgery, University of Clinical Center of Serbia (Belgrade, Serbia) and whose ileostomy was closed. Study participants were interviewed over the telephone using the Serbian version of the HPA which was translated according to the internationally accepted methodology for translation and adaptation of questionnaires. The confirmatory factor analysis suggested that the fit indices for 5-factor structure of the HPA were acceptable-to-good: Goodness of fit index = 0.939; Tucker Lewis fit index = 0.989; Comparative fit index = 0.992; Root Mean Square Error of Approximation = 0.019. Cronbach's alpha coefficients for Health Neuroticism, Health Extraversion and Health Agreeableness were>0.7 and for Health Openness and Health Conscientiousness were >0.4. Predictive validity testing suggested that not having complications with the ileostomy and a longer time since ileostomy closure were associated with stronger Health Agreeableness. Also, a longer time since ileostomy closure was associated with stronger Health Conscientiousness. The Serbian version of the HPA showed good construct validity and acceptable internal consistency. This is an important tool in further research of personality and health outcomes among rectal cancer survivors.

The Association Between Personality Traits and Substance Use Among Advanced Level Students in Western Province, Sri Lanka: A Cross-sectional Study.

Background: While personality predominantly influences human cognition, emotion, and behavior, there is still an unresolved research gap concerning the association between personality and substance use within the Sri Lankan context. Methods: This descriptive cross-sectional study aimed to investigate the association between personality traits and substance use among advanced-level students aged over 18 in Western province, Sri Lanka, in 2023. Data collection was carried out using self-administered paper-pencil questionnaires. The study variables were measured using the brief version of the Big Five Personality Inventory and the Alcohol, Smoking, and Substance Involvement Questionnaire. Data analysis involved the use of the chi-square test and Spearman correlation. Findings: Of the 441 enrolled participants, 422 provided correct responses to the questionnaire. Among them, 154 (36.5%) reported substance use. The majority of students initiated substance use at the age of 17. The results reveal a significant association between the openness personality trait and substance use among advanced-level students in Western province. Additionally, there was a statistically significant positive correlation between the extroversion personality trait and amphetamine use among advanced-level students. Conclusion: The findings highlight a significant association between specific personality traits, particularly openness and extroversion, and substance use among advanced-level students in Western province, Sri Lanka. These results emphasize the significance of considering personality factors in understanding and addressing substance use behaviors among youth populations. Further research and targeted interventions are necessary to delve deeper into these associations and develop effective prevention and intervention strategies.

Do Behavioral Characteristics Influence the Breast Cancer Diagnosis Delay? Evidence From French Retrospective Data.

OBJECTIVES: This study aimed to analyze the behavioral determinants of breast cancer (BC) diagnosis delays in France. To do so, we investigated whether time discounting, risk tolerance, and personality traits influenced the BC diagnosis delay of patients. METHODS: We used original retrospective data collected on 2 large online patient networks from 402 women diagnosed of BC. The BC diagnosis delay was measured by the difference between the date of diagnosis and the date of first symptoms. Time discounting and risk tolerance are measured with both self-reported questions and hypothetical lotteries. Personality traits are measured with the 10-item Big Five indicator. Ordinary least square and probit models were used to analyze whether these behavioral characteristics influenced the BC diagnosis delay. RESULTS: Results showed that risk tolerance and time discounting were not significantly associated with the BC diagnosis delay. However, we found a longer diagnosis delay for women with a neuroticism personality trait (standardized coefficients ranged from 0.104 [P-value = .036] to 0.090 [P-value = .065]). CONCLUSIONS: Overall, our findings underline the need for an increased consideration of cancer screening public health policy for women with mental vulnerabilities since such vulnerabilities were found to be highly correlated with a neuroticism personality trait.

Personality and Transition From Mild Cognitive Impairment to Normal Cognition vs Dementia.

OBJECTIVES: Mild cognitive impairment (MCI) is a critical stage preceding incident dementia, but not all individuals with MCI progress to dementia and some revert to normal cognition. This study examined whether personality is associated with the probability of transition from MCI to normal cognition or dementia. DESIGN: Longitudinal observational study. SETTING AND PARTICIPANTS: Older adults with MCI from the Health and Retirement Study (N = 1608, 56% female, mean age = 72.29, SD = 9.91). Personality traits; cognitive status; and demographic (age, sex, education, race, and ethnicity), clinical (diabetes, hypertension), behavioral (smoking, physical activity), psychological (depressive symptoms), and genetic (apolipoprotein E ε4) covariates were obtained in 2006/2008. Follow-up data on cognitive status were collected every 2 years up to the 2020 wave. METHODS: Cox regression analyses tested the association between personality and reversion from MCI to normal cognition and progression to dementia, controlling for demographic, clinical, behavioral, psychological, and genetic covariates. RESULTS: Controlling for demographic factors, lower neuroticism and higher openness and conscientiousness were associated with a higher likelihood of reversion from MCI to normal cognition and a lower risk of progression to dementia over time. Higher agreeableness was related to a lower risk of progression to dementia. Clinical, behavioral, psychological, and genetic factors partially accounted for these associations. There was little evidence that demographic, genetic factors, or baseline cognition moderated these associations. CONCLUSIONS AND IMPLICATIONS: Personality traits can help identify individuals who are more likely to revert from MCI and not progress to dementia. These findings suggest that even during mild impairment, personality may modulate dementia risk and thus inform targeted interventions.

Surgical treatment may improve depressive and hysterical traits in temporal lobe epilepsy with hippocampal sclerosis: Study using the Minnesota Multiphasic Personality Inventory.

Aim: The influence of surgeries on psychiatric symptoms and personality traits is not well known in patients with intractable temporal lobe epilepsy (TLE). We investigated changes in personality traits with respect to postoperative seizure outcomes, etiology, side of surgery, and sex differences. Methods: Clinical information was retrospectively collected for 44 patients whose Minnesota Multiphasic Personality Inventory (MMPI) was examined before and 1 year after surgical treatment for drug-resistant TLE. Postoperative changes in MMPI T-scores were analyzed using a paired t-test. Participants were divided into two groups based on postoperative seizure outcome, the presence or absence of hippocampal sclerosis (HS) as the etiology, side of surgery, and sex differences. The effect of these clinical factors on postoperative changes in MMPI T-scores was evaluated using analysis of covariance (P-values < 0.05). Results: The hypochondria (Hs) scale decreased significantly in all patients (p = 0.022). The postoperative seizure-free group had a significant decrease in the depression (D) scale (p = 0.037). The HS group had significant decreases in the D scale and the hysteria (Hy) scale (p = 0.016 and 0.004, respectively), and a significant increase in the masculinity-femininity (Mf) scale (p = 0.009). No significant differences existed between the sides of surgery or sex. Conclusion: Depressive traits were improved in patients with postoperative seizure freedom. Depressive and hysterical traits were improved in patients with HS, which may be attributed to a reduction in anxiety and fear associated with aura. Most personality traits are not significantly changed or exacerbated by surgical treatment of TLE.

A systematic review of personality and musculoskeletal disorders: evidence from general population studies.

Introduction: We conducted a systematic review to evaluate the quality and extent of evidence on associations between personality disorders (PDs) and musculoskeletal disorders (MSDs) in population-based studies, since these disorders are leading causes of disease burden worldwide. Methods: A search strategy of published, peer-reviewed and gray literature was developed in consultation with a liaison librarian and implemented for Embase, CINAHL Complete, Medline Complete, and PsycINFO via the EBSCOhost platform from 1990 to the present and CORDIS and ProQuest Dissertations & Theses Global, respectively. The inclusion criteria were as follows: I) general population participants aged ≥15 years; II) self-report, probable PD based on positive screen, or threshold PD according to the DSM-IV/5 (groupings: any, Clusters A/B/C, specific PD) or ICD-10/11; III) MSDs identified by self-report or ICD criteria (arthritis, back/neck conditions, fibromyalgia, osteopenia/osteoporosis) and III) cohort, case-control, and cross-sectional study designs. Two reviewers independently screened articles and extracted the data. Critical appraisal was undertaken using the Joanna Briggs Institute checklists for systematic reviews of etiology and risk. A descriptive synthesis presents the characteristics of included studies, critical appraisal results, and descriptions of the main findings. This review adhered to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Results: There were 11 peer-reviewed, published articles included in this review (n = 9 cross-sectional and n = 2 case-control studies); participants were ≥18 years in these studies. No published gray literature was identified. Semi-structured interviews were the most common method to ascertain PDs; all studies utilized self-reported measures to identify MSDs. Overall, we detected limited and conflicting evidence for associations between PDs and MSDs. Discussion: The main result may be explained by lack of population-based longitudinal evidence, heterogenous groupings of PD, and few comparable cross-sectional and case-control studies. Strengths of the review include a comprehensive search strategy and a discussion of mechanisms underlying possible associations between PDs and MSDs. Conclusions: The quality of most studies included in this review that examined associations between PD and MSDs in general population adults was high. However, the results demonstrated limited and conflicting evidence for these associations, in part, due to lack of comparable evidence, which should be addressed in future research.

Dysregulation of Plasma Growth Factors and Chemokines in Cocaine Use Disorder: Implications for Dual Diagnosis with Schizophrenia and Antisocial Personality Disorder in an Exploratory Study.

INTRODUCTION: Dual diagnosis in individuals with cocaine use disorders (CUDs) presents a mental health challenge marked by an increased susceptibility to disabling morbidities and premature mortality. Despite extensive research on depression and anxiety, other prevalent comorbidities, such as psychotic and personality disorders, have received less attention. This study explores inflammation-related mediators as potential biomarkers for CUD and dual diagnosis with schizophrenia (SCZ) or antisocial personality disorder (APD). METHODS: This exploratory study included 95 participants, comprising 40 healthy subjects and 55 abstinent patients with CUD. Lifetime CUD was diagnosed either as single diagnosis (CUD group, N = 25) or as a dual diagnosis (DD group. N = 30) with SCZ (CUD+SCZ subgroup) or APD (CUD+APD subgroup). Participants were clinically assessed, and the plasma concentrations of growth factors (i.e., G-CSF, BDNF, and VEGF-A) and chemokines (i.e., CCL11/eotaxin-1, CCL2/MCP-1, and CXCL12/SDF-1) were determined and log(10)-transformed for analysis. RESULTS: Growth factors and chemokines were dysregulated by CUD and psychiatric diagnoses. Specifically, patients in the CUD group exhibited significantly lower concentrations of G-CSF and CCL11/eotaxin-1 than the control group. In contrast, the DD group showed significantly higher concentrations of all analytes than both the CUD and control groups. Additionally, no differences in these analytes were observed between the CUD+SCZ and CUD+APD subgroups within the DD group. Regarding cocaine-related variables, significant associations were identified in the CUD group: an inverse correlation between the age at first cocaine use and the concentrations of BDNF and CCL2/MCP-1; and a positive correlation between the duration of the cocaine abstinence and the concentrations of BDNF and CCL11/eotaxin-1. Lastly, a logistic regression model incorporating all these analytes demonstrated high discriminatory power in distinguishing patients with CUD alone from those with dual diagnosis. CONCLUSIONS: Individuals with dual diagnosis of CUD exhibit elevated concentrations of growth factors and chemokines, distinguishing them from those with CUD alone. It is unclear whether the differences in these inflammatory mediators are specific to the presence of SCZ and APD. The study highlights potential biomarkers and associations, providing valuable insights into the intricate interplay of CUD and psychiatric disorders to enhance clinical diagnosis and therapeutics.

Narcissistic personality disorder in the ICD-11: Severity and trait profiles of grandiosity and vulnerability.

Modern diagnostic and classification frameworks such as the ICD-11 and DSM-5-AMPD have adopted a dimensional approach to diagnosing personality disorder using a dual "severity" and "trait" model. As narcissistic personality has historically struggled to be adequately captured in dominant diagnostic systems, this study investigated the utility of the new ICD-11 framework in capturing diverse narcissistic expressions. Participants were mental health clinicians (N = 180, 67% female, age = 38.9), who completed ratings of ICD-11 personality severity, trait domains and a clinical reflection for two hypothetical case vignettes reflecting either prototypical "grandiose" or "vulnerable" narcissism. The majority of clinicians (82%) endorsed a diagnosis of personality disorder for both grandiose and vulnerable vignettes. Discriminant elements of personality impairment included rigid, unrealistically positive self-view, low empathy and high conflict with others for grandiosity, and incoherent identity, low self-esteem and hypervigilant, avoidant relations with others for vulnerability. Regarding trait profile, grandiose narcissism was predominately dissocial whereas vulnerable narcissism was primarily associated with negative affectivity and detachment. Qualitative responses highlight distinct clinical themes for each presentation. These findings suggest that clinicians using the ICD-11 framework are able to identify common core elements of personality dysfunction in grandiose and vulnerable narcissism while also recognizing their distinctive differences.

Physical multimorbidity in psychiatric patients with personality disorders: Insights within the ICD-11 framework.

OBJECTIVE: Recent research has revealed poor physical health among individuals with personality disorders (PDs). We aimed to compare chronic physical illnesses (CPI) and chronic physical multimorbidity (CPM) prevalence between the general population (GEP) and PD patients, and to explore the relationship between CPM and various aspects of PD, predominantly within the ICD-11 framework. METHODS: This cross-sectional study included 126 PD patients and 126 matched controls from the GEP. Patients were evaluated for the ICD-11 PD severity and maladaptive personality domains, subjective emptiness, and reflective functioning. CPI was assessed using a standardized self-report questionnaire. RESULTS: PD patients had a higher mean number of CPIs (2.05 vs. 1.02) and a more frequent CPM occurrence (49.2% vs. 26.2%) compared to the matched controls (p < .001). The ICD-11 PD severity (OR = 1.143, p = .007) and maladaptive domain Negative affectivity (OR = 4.845, p = .002), and poor reflective functioning (OR = 1.694, p = .007) were significant predictors of CPM, independent of sociodemographic, clinical and lifestyle factors. Negative affectivity showed the most robust effect on CPM, while smoking did not significantly mediate these relationships. CONCLUSION: Our study found increased CPM burden in PD patients and a link between CPM and various PD aspects under the ICD-11 framework, highlighting the need for more integrated healthcare.

Exploring the Personality Characteristics of Rhinoplasty Patients: Perfectionism, Rumination, and Self-Compassion.

OBJECTIVE: This study investigates differences in personality characteristics, including perfectionism, ruminative thinking style, and self-compassion, between individuals who have undergone rhinoplasty and a control group without any history of cosmetic surgery. METHODS: The study included 33 adult patients who underwent rhinoplasty between 2021 and 2023 at Bursa Uludag University Faculty of Medicine Hospital and 33 adult patients who visited our centre for other complaints as a control group. The rhinoplasty group consisted of primary surgical patients with functional and cosmetic concerns, excluding those who sought revision surgery or had only functional problems. The control group consisted of individuals with no prior cosmetic surgery history and no expectations of aesthetic interventions. Psychiatric analysis was performed using Frost multidimensional perfectionism scale, ruminative thinking style questionnaire, and self-compassion scale. RESULTS: This research revealed that individuals who had rhinoplasty scored higher in perfectionism 109.3 (±23.3) and ruminative thinking 87.9 (±22) compared to those who did not undergo surgery 94.15 (±22.2) and 77.7 (±23), respectively. Additionally, the rhinoplasty group had lower self-compassion scores, 80.4 (±17.3), than the control group, 86.1 (±11.2). Statistically significant differences were observed in perfectionism between the groups (p = 0.009). In rhinoplasty patients, a notably positive correlation was found between perfectionism and ruminative thinking scores (r = 0.482; p = 0.005), while a moderately significant negative correlation was observed between self-compassion and ruminative thinking scores (r = - 0.465; p = 0.006). CONCLUSION: Individuals who undergo rhinoplasty generally show increased levels of perfectionism and are more prone to ruminative thinking. They also demonstrate reduced self-compassion compared to non-surgical control groups. Cosmetic surgeons should be aware of these psychological trends and consider using appropriate scales during pre-surgery consultations and follow-up visits. Adopting this informed approach can improve the surgeon-patient relationship and help overcome communication challenges.
