Abstract
This is the first study exploring how temperament and character personality dimensions impact self-reported resilience in major depressive disorder (MDD) and bipolar disorder (BD). We included 130 euthymic patients with affective disorders (AFD; 66 MDD and 64 BD) and 134 healthy controls (HC). Connor and Davidson resilience scale and Temperament and Character Inventory (TCI-140) were administered. Multiple linear regressions and interaction analyses were performed. Mediation analyses examined if personality dimensions explained group differences in resilience. Resilience was lower in MDD and BD vs. HC and in MDD vs. BD, adjusting for sex, age and education. Higher resilience was predicted by lower harm avoidance (HA) and higher persistence (P) in AFD and MDD, lower HA in BD and higher P and self-directedness (SD) in HC. However, only HA and P had a group-specific effect on resilience in AFD vs. HC. In mediation analyses, specific TCI dimensions at least partially explained differences in resilience: HA, P and SD in AFD or MDD vs. HC; SD in BD vs. HC; P in BD vs. MDD. Concludingly, two temperament traits (HA, P) and a character trait (SD) predict resilience in AFD. Focusing on personality could identify sources of compromised resilience as potential treatment targets.

Empathy and Violence in Schizophrenia and Antisocial Personality Disorder. Healthcare (Basel) 2023; 12:89. [PMID: 38200995 PMCID: PMC10779118 DOI: 10.3390/healthcare12010089] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Revised: 12/28/2023] [Accepted: 12/28/2023] [Indexed: 01/12/2024] Open
Abstract
A paucity of cognitive and affective features of empathy can be correlated with violent behavior. We aimed to identify differences in empathy among four groups in a sample of 100 male participants: (1) 27 violent offenders with schizophrenia, (2) 23 nonviolent patients with schizophrenia, (3) 25 patients with antisocial personality disorder, and (4) 25 subjects from the general population, who formed the control group. Schizophrenia symptoms were quantified with the Positive and Negative Syndrome Scale. Empathy was measured with the empathy quotient. Theory of mind was evaluated using (a) the first-order false-belief task, (b) the hinting task, (c) the faux pas recognition test and (d) the "reading the mind in the eyes" test (revised). Differences noted among the groups were age (controls were younger) and educational status (antisocials were less educated). The empathy quotient scoring (p < 0.001) and theory-of-mind tests (p < 0.001) were distinct between the control group and the three other groups of participants, but not among the three patient groups. Patients with antisocial personality disorder, violent psychotic offenders and psychotic nonviolent patients show no remarkable differences in affective or cognitive empathy tests, but they all present deficits in empathy and theory of mind when compared to controls.

Abstract
Chronic Low Back Pain (CLBP) is a very common health problem that has a great negative impact on the quality of life and the psychological well-being of backache patients. Literature findings have shown that a conventional physiotherapeutic approach is a beneficial choice for CLBP management. The aim of this study was to examine the short-term effects of a conservative physical treatment on depression, anxiety, somatic symptom disorders (SSD), quality of life, pain and disability in Greek individuals suffering from CLBP. Seventy-five CLBP patients were recruited using random systematic sampling. All subjects received ultrasound, low-level laser, massage, transcutaneous electrical nerve stimulation (ΤENS) and alongside an exercise program (sum of 10 sessions, 5 times per week). The intervention was assessed by comparing pre and post outcome measurements based on the Hospital Anxiety and Depression Scale (HADS), Somatic Symptom Scale-8 (SSS-8), EuroQol 5-dimension 5-level (EQ-5D-5L), Roland-Morris Disability Questionnaire (RMDQ) and Pain Numerical Rating Scale (PNRS) instruments. The mean age of the sample was 60.8 years (±14.4) and nearly one out of four (25.3%) was obese. After the end of the treatment, there were improvements in EQ-5D-5L indices and decreases in HADS, SSS-8, RMDQ and PNRS scores, which were found to be statistically significant. Greater effect size was found in PNRS (d=0.75), followed by EQ-5D-5L index value scale (d=0.42), SSS-8 (d=0.38), EQ-5D-5L VAS (d=0.36), RMDQ (d=0.29), HADS-A (d=0.16) and HADS-D (d=0.14). Men and women had similar changes in all under-study scales after the treatment, while besides pain scale, the pre-intervention scores as well as the degree of change in all scores were similar across all Body Mass Index (BMI) levels. In conclusion, convectional physical treatment was found to be an effective option in improving considerably the psychological status and quality of life, while also decreasing functional disability and pain in CLBP patients in the short run.

Abstract
Literature findings have suggested that psychological factors, including anxiety, depression and somatic symptom disorder (SSD), are predictors of poor outcomes in individuals with chronic low back pain (CLBP). The aim of this study was to examine the correlations between anxiety, depression and SSD with pain, disability and health-related quality of life (HRQoL) in Greek CLBP patients. Ninety-two participants with CLBP recruited using random systematic sampling from an outpatient physiotherapy department, who completed a battery of paper-and-pencil questionnaires included items on demographic characteristics, as well the Numerical Pain Rating Scale (NPRS) for pain, the Rolland-Morris Disability Questionnaire for disability (RMDQ), the EuroQoL 5-dimension 5-level (EQ-5D-5L) for health status, the Somatic Symptom Scale-8 (SSS-8) for SSD, the Hospital Anxiety and Depression Scale (HADS) for anxiety and depression. A Mann-Whitney test and a Kruskall-Wallis test were used for the comparison of continuous variables between two groups and among more than two groups, respectively. Moreover, Spearman correlations coefficients were used to explore the association between subjects' demographics, SSS-8, HADS-Anxiety, HADS-Depression, NPS, RMDQ and EQ-5D-5L indices. Predictors of health status, pain and disability were assessed using multiple regression analyses, whereas the level of statistical significance was set at p<0.05. The response rate was 94.6% (87 participants, 55 of whom were women) and the mean age of the sample was 59.6 years (SD=15.1). A tendency of weak negative associations was noted between scores of SSD, anxiety and depression with EQ-5D-5L indices, whereas only a weak positive correlation was found between levels of SSD with pain and disability. After examining in a multiple regression analysis, only SSD emerged as prognostic factor of poor HRQoL, greater levels of pain and disability. In conclusion, the elevated scores of SSD significantly predict worse HRQoL, intense pain and severe disability in Greek CLBP patients. Further research is needed to test our findings in larger and more representative samples of the Greek general population.

A modern web-based health promotion program for patients in Greece with diabetes 2 and obesity: an interventional study. BMC Public Health 2023; 23:639. [PMID: 37013500 PMCID: PMC10069363 DOI: 10.1186/s12889-023-15557-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2022] [Accepted: 03/29/2023] [Indexed: 04/05/2023] Open
Abstract
BACKGROUND Health promotion programs are most beneficial in chronic diseases such as diabetes and morbid obesity, which can be positively affected by changes in attitudes, beliefs, and lifestyle. OBJECTIVES This study aimed to develop an internet-based modern Health Promotion model using interactive online applications through continuing education and participation. METHODS The goal was to positively impact knowledge, behavior, and quality of life for patients with obesity and/or diabetes. This is a prospective interventional study on patients with obesity or type 2 diabetes. Seventeen two patients who met the inclusion criteria were distributed randomly into two groups (control and intervention) from 2019 to 2021 in Greece. All the participants were given questionaries concerning quality of life anxiety and depression (HADS) attitudes and beliefs, knowledge about their condition and general questions to establish a baseline. A traditional health promotion model was followed for the control group. For participants in the intervention group, a web-based health promotion program was created according to the goals of the research. Participants were instructed to log on 1-2 times a week for 5-15 min, with the understanding that the research team would be monitoring their activities. The website included two knowledge games and personalized educational material based on their needs. RESULTS The sample comprised 72 patients (36 in control and 36 in the intervention groups). The mean age was 47.8 years for the control group and 42.7 years for the intervention group (p = 0.293). Both study groups had a significant increase in knowledge score on diabetes (Control group:3,24, Intervention group 11,88 p < 0,001) and obesity (Control group:4,9, Intervention group 51,63 p < 0,001) along with a positive attitude score towards fighting obesity (Control group: 1,8, Intervention group 13,6 p < 0,001). Still, the overall change was more remarkable for the intervention group, as indicated by the significant interaction effect of the analysis. Anxiety was decreased only in the intervention group (Control group:0,11, Intervention group - 0,17 p < 0,005). Analysis for QOL during follow-up showed that Physical Health and Level of Independence was improved in both study groups but the degree of improvement was more significant in the intervention group (Control group 0,31,Intervention group 0,73 p < 0,001). Psychological Health was improved only in the intervention group, with better scores at 6 and 12 months compared to controls (Control group 0,28,Intervention group 1,42 p < 0,001). Furthermore, Social relationships were improved only in the intervention group (Control group 0,02, Intervention group 0,56 p < 0,001). CONCLUSIONS The results of the present study showed that the participants in the intervention group showed significant improvement in knowledge, attitudes, and beliefs after using the internet as a learning tool. The intervention group also showed significantly reduced anxiety and depression arising from chronic illness. All of this resulted in an improved quality of life regarding physical Health, mental Health, and social relationships. Technology and online-based health promotion programs can revolutionize how we approach the prevention and management of chronic and terminal illnesses by improving accessibility, personalizing care, increasing engagement and motivation, improving data analysis, and disease management.

Abstract
The seven-item Hospital Anxiety and Depression Scale Depression subscale (HADS-D) and the total score of the 14-item HADS (HADS-T) are both used for major depression screening. Compared to the HADS-D, the HADS-T includes anxiety items and requires more time to complete. We compared the screening accuracy of the HADS-D and HADS-T for major depression detection. We conducted an individual participant data meta-analysis and fit bivariate random effects models to assess diagnostic accuracy among participants with both HADS-D and HADS-T scores. We identified optimal cutoffs, estimated sensitivity and specificity with 95% confidence intervals, and compared screening accuracy across paired cutoffs via two-stage and individual-level models. We used a 0.05 equivalence margin to assess equivalency in sensitivity and specificity. 20,700 participants (2,285 major depression cases) from 98 studies were included. Cutoffs of ≥7 for the HADS-D (sensitivity 0.79 [0.75, 0.83], specificity 0.78 [0.75, 0.80]) and ≥15 for the HADS-T (sensitivity 0.79 [0.76, 0.82], specificity 0.81 [0.78, 0.83]) minimized the distance to the top-left corner of the receiver operating characteristic curve. Across all sets of paired cutoffs evaluated, differences of sensitivity between HADS-T and HADS-D ranged from -0.05 to 0.01 (0.00 at paired optimal cutoffs), and differences of specificity were within 0.03 for all cutoffs (0.02-0.03). The pattern was similar among outpatients, although the HADS-T was slightly (not nonequivalently) more specific among inpatients. The accuracy of HADS-T was equivalent to the HADS-D for detecting major depression. In most settings, the shorter HADS-D would be preferred.

The Impact of the COVID-19 Pandemic and Associated Control Measures on the Mental Health of the General Population : A Systematic Review and Dose-Response Meta-analysis. Ann Intern Med 2022; 175:1560-1571.

Abstract
BACKGROUND To what extent the COVID-19 pandemic and its containment measures influenced mental health in the general population is still unclear. PURPOSE To assess the trajectory of mental health symptoms during the first year of the pandemic and examine dose-response relations with characteristics of the pandemic and its containment. DATA SOURCES Relevant articles were identified from the living evidence database of the COVID-19 Open Access Project, which indexes COVID-19-related publications from MEDLINE via PubMed, Embase via Ovid, and PsycInfo. Preprint publications were not considered. STUDY SELECTION Longitudinal studies that reported data on the general population's mental health using validated scales and that were published before 31 March 2021 were eligible. DATA EXTRACTION An international crowd of 109 trained reviewers screened references and extracted study characteristics, participant characteristics, and symptom scores at each timepoint. Data were also included for the following country-specific variables: days since the first case of SARS-CoV-2 infection, the stringency of governmental containment measures, and the cumulative numbers of cases and deaths. DATA SYNTHESIS In a total of 43 studies (331 628 participants), changes in symptoms of psychological distress, sleep disturbances, and mental well-being varied substantially across studies. On average, depression and anxiety symptoms worsened in the first 2 months of the pandemic (standardized mean difference at 60 days, -0.39 [95% credible interval, -0.76 to -0.03]); thereafter, the trajectories were heterogeneous. There was a linear association of worsening depression and anxiety with increasing numbers of reported cases of SARS-CoV-2 infection and increasing stringency in governmental measures. Gender, age, country, deprivation, inequalities, risk of bias, and study design did not modify these associations. LIMITATIONS The certainty of the evidence was low because of the high risk of bias in included studies and the large amount of heterogeneity. Stringency measures and surges in cases were strongly correlated and changed over time. The observed associations should not be interpreted as causal relationships. CONCLUSION Although an initial increase in average symptoms of depression and anxiety and an association between higher numbers of reported cases and more stringent measures were found, changes in mental health symptoms varied substantially across studies after the first 2 months of the pandemic. This suggests that different populations responded differently to the psychological stress generated by the pandemic and its containment measures.

Residual cognitive and psychosocial functional impairment in outpatients in Greece who responded to conventional antidepressant monotherapy treatments for major depressive disorder (MDD). J Affect Disord 2022; 314:185-192. [PMID: 35817305 DOI: 10.1016/j.jad.2022.07.009] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/12/2022] [Revised: 06/28/2022] [Accepted: 07/05/2022] [Indexed: 01/01/2023]
Abstract
BACKGROUND Patients with MDD may experience diverse residual symptoms after clinical response to antidepressant treatment. Among these symptoms, cognitive problems in executive functioning are prominent and make functional recovery largely an unmet need for MDD patients. In this study we assessed cognitive symptoms and functional impairment in patients with MDD responding to antidepressant treatment. METHODS This was a national, multi-site, non-interventional, cross-sectional study of depressive symptomatology, cognitive performance and psychosocial functioning in Greek outpatients with MDD who had clinically responded to antidepressant treatment. Both clinician- and patient- rated measures were employed. Symptom remission was assessed with the Montgomery Asberg Depression Rating Scale (MADRS) total score (≤12) and functional recovery was assessed with the Sheehan Disability Scale (SDS) score (<6). RESULTS 335 MDD patients participated in the study. After antidepressant monotherapy approximately 60 % of responders and 40 % of remitted patients did not meet the functional recovery criterion. More than 60 % of responders had concentration difficulties as assessed by MADRS item. Patient reported cognitive symptoms were statistically significantly associated with functionality (β coefficient = 0.126, p-value = 0.027). LIMITATIONS Non-interventional study design and lack of a control group or active comparator/reference. CONCLUSIONS This study highlights the persistence of decreased cognitive performance, particularly in executive functioning in patients with MDD who have shown response and/or remission to antidepressant treatment. This appears to contribute to psychosocial functional impairment. Patient-reported cognitive and psychosocial functioning impairment should be included in routine clinical monitoring of outcomes in MDD treatments.

Abstract
Chronic Pain (CP) is defined as pain that persists or recurs for more than 3 to 6 months and may be conceived as a health condition in its own right. CP is a frequent condition, affecting an estimated 20% of people worldwide and requires special treatment and care. CP can contribute to depression, anxiety, sleep disturbances, poor quality of life and increased health care costs. Psychosocial approaches based on a cognitive conceptualization of pain can provide a solid foundation for research and clinical work. The development of a 10 week-session group treatment was based on key principles from the literature on Cognitive Behavioral Therapy for Chronic Pain (CBT-CP) and Creative Arts Therapy, integrated with advances in research on CP management framework. The aim of this study is to evaluate a CBT-CP arts-based group intervention for patients with non-malignant CP addressing the biopsychosocial factors that influence pain perception. A total of 100 University Pain Management Unit outpatients participated, 50 in the intervention group and 50 in the control group (treatment as usual). In analyses of the pretest-posttest research design intervention including all participants, treatment gains were observed in almost all domains examined: severity of pain measured by the Brief Pain Inventory, conceptualization of mental pain measured by the Orbach and Mikulincer Mental Pain Scale, tolerance for psychological pain measured by the Tolerance for Mental Pain Scale, anxiety and depression levels measured by the Hospital Anxiety and Depression Scale, and quality of life measured by the WHO Quality of Life-BREF Questionnaire. The participants' mean age was 52.3 years and most were female (84%). Findings suggest that postprogram, there was significant reduction in pain intensity (p<0.001), depressive symptoms (p<0.001), confusion about pain (p=0.037), and improvement of emotional distress tolerance (p=0.012) and global health-related quality of life (p<0.001) in the intervention group. Beneficial effects can be expected from the implementation of an integrated CP intervention (including: creative and CBT techniques) reappraising some of the coping responses defined as adaptive within current psychosocial non-malignant CP regimens.

Abstract
We aimed to examine and compare the attitudes of physicians and law professionals on modern bioethical issues. Euthanasia, physician assisted suicide and abortion were selected for this study, as they underline the conflict between human life as a fundamental value, and the individual's right to self-determination. The demand of euthanasia and physician assisted suicide services reflects each person's right to decide on the way their life will end, while the legalization of abortion determines the individual's right to self-determination. These are complex issues with moral, religious and social implications, and as such tend to divide public opinion. In order to investigate their attitudes, physicians of all specialties, as well as law professionals from all over Greece, were invited to participate in the study. In total, 220 professionals responded to the call and participated in the survey. The professionals involved showed fairly high rates of agreement in all the issues studied, but a significant difference in results was found when the occupation of participants was set as a criterion, with physicians being more negative to euthanasia, physician assisted suicide and abortion than lawyers. Religiousness, age and male sex were negatively correlated with "positive" attitudes towards euthanasia, physician assisted suicide and abortion. Moreover, participants' attitudes towards euthanasia and physician assisted suicide were found to predict their attitudes towards abortion, indicating a single ideological direction of agreement or disagreement, accordingly. Individuals' attitudes and opinions are complicated issues, not easy to be categorized. However, it is of scientific interest to shape a legislative framework that is close to the social consensus, ideological evolution and moral needs. This study tried to pave the way for a modern approach to the issues of euthanasia, physician assisted suicide and abortion.

Abstract
INTRODUCTION Bipolar disorder (BD) is associated with impairment in cognitive domains such as verbal memory and executive functions. Very few studies have assessed dehydroepiandrosterone sulphate (DHEA-S) in BD and its relation to cognitive functioning despite evidence showing its regulatory effects on glucocorticoid action. The aim of our study was to explore the association of cortisol, DHEA-S, and cortisol to DHEA-S ratio with visuospatial memory and executive functioning in BD. METHODS Cognitive performance of 60 bipolar I patients and 30 healthy subjects was evaluated by using Cambridge Neuropsychological Test Automated Battery tasks targeting visuospatial memory (spatial recognition memory) and executive functions (planning [Stockings of Cambridge; SOC] and attentional set shifting [ID/ED]). Morning serum cortisol and DHEA-S levels were measured in patients. Main effects of cortisol, DHEA-S, and cortisol/DHEA-S ratio for each neurocognitive task were explored in multiple regression analyses correcting for demographic and clinical parameters as well as treatment-related factors (current use of antipsychotic and mood stabilizer medication). RESULTS Bipolar patients showed poorer performance than healthy subjects in planning and attentional set shifting but not in visuospatial memory. Cortisol to DHEA-S ratio predicted worse performance in planning (SOC). CONCLUSIONS This is the first study to assess memory and executive function in BD in relation to DHEA-S and cortisol to DHEA-S ratio. We report an association of cortisol to DHEA-S ratio with worse performance in planning in bipolar I patients, which warrants further investigation.

Abstract
The association of cortisol with cognition has been understudied in Bipolar Disorder (BD); available evidence is inconsistent while it is unknown whether cortisol's effects vary across neurocognitive domains implicating different brain structures. This study aimed to examine the association of cortisol with two cognitive tasks targeting visual memory and executive function (planning) in BD, related to the hippocampus and prefrontal lobe, respectively. Cambridge Neuropsychological Test Automated Battery (CANTAB) tasks targeting paired associative learning (PAL) and planning (Stockings of Cambridge; SOC) were administered to 60 BD type I patients. Basal serum cortisol was also measured. Higher cortisol was associated with worse performance in PAL, but not SOC, after controlling for gender, education, illness duration and treatment with mood stabilizers. This is the first study to examine the association of cortisol with neurocognitive function in BD while controlling for clinicodemographic and treatment-related factors. We found a significant association of cortisol with hippocampal-related visual memory/learning but not with prefrontal lobe-related executive function, suggesting domain-specific underlying mechanisms of cognitive dysfunction in BD. Future studies should further explore cortisol's brain structure-specific effects on cognitive functioning in BD.

Validation of the Greek ORTO-15 questionnaire for the assessment of orthorexia nervosa and its relation to eating disorders symptomatology. Eat Weight Disord 2021; 26:2471-2479. [PMID: 33475990 DOI: 10.1007/s40519-020-01080-6] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/09/2020] [Accepted: 11/22/2020] [Indexed: 12/11/2022] Open
Abstract
PURPOSE The aim of the study was the validation of the Greek version of the ORTO-15 questionnaire. An additional aim was to explore the relation between orthorexic and eating disorder behaviors in a sample of Greek students. METHODS ORTO-15 was translated and adapted in the Greek language. After its final version was drafted, its test-retest reliability was checked. Then, the questionnaire was administered to 120 students of psychology along with EAT-26. Additionally, demographics, BMI and information related to eating disorders were collected. RESULTS The Greek version of the ORTO-15 questionnaire showed acceptable internal consistency (Cronbach's a 0.7). Factor analysis produced a three-factor model similar to the original English version of the questionnaire. The correlation of ORTO-15 and EAT-26 revealed that higher measurements in the diet and bulimia EAT-26 scale were related to increased orthorexic symptomatology. Finally, there was no significant correlation between the 3 factors of the ORTO-15 (emotional, rational and behavioral) and age, education or Body Mass Index. CONCLUSIONS This study is the first attempt to assess orthorexia nervosa in a Greek student population. ORTO-15 was found to be a reliable tool for the measurement of orthorexia in Greece. Finally, in accordance with other studies, orthorexic symptoms were partially related to eating disorder symptomatology, thus raising the question of possible similarities and overlap between the two clinical constructs. LEVEL OF EVIDENCE Level V, Cross-sectional descriptive study.

An age-period-cohort study of completed suicides in Greece: Patterns and implications for suicide prevention. Psychiatry Res 2021; 306:114260. [PMID: 34785425 DOI: 10.1016/j.psychres.2021.114260] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/12/2021] [Revised: 10/23/2021] [Accepted: 10/30/2021] [Indexed: 10/19/2022]
Abstract
Suicide is a dynamic phenomenon. Psychiatric medication intake, illicit drug and alcohol use or the preference for particular suicide methods shift continuously over time. To capture such variations -and their potential implications for suicide prevention-, we researched the forensic records of suicide cases for the period 1992-2016 at a large department of forensic medicine and conducted age-period-cohort (APC) analyses of our sample (1162 suicides, 77.45% males, 22.25% females). We primarily investigated socio-demographic and toxicological parameters. Benzodiazepine, alcohol and illicit drug use increased considerably towards the younger cohorts. The segment of individuals of foreign nationality raised significantly too; likewise, the proportion of prison suicides. Hanging appears increasingly preferred by the younger APCs (the opposite is true for jumping). Hanging seems more popular among males, prisoners, and those under the influence of illicit drugs; jumping by females and those less likely to have consumed alcohol or illicit drugs. Given that the method of a prior attempt, if a highly lethal one, usually gets repeated in the completed suicide, a history of an attempt by hanging should never be underestimated. The mental health needs of immigrants and prisoners look inadequately addressed. Young-middle aged immigrant prisoners appear a group at high suicide risk.

Cerebral Venous Sinus Thrombosis and Thrombotic Events After Vector-Based COVID-19 Vaccines: A Systematic Review and Meta-analysis. Neurology 2021; 97:e2136-e2147. [PMID: 34610990 DOI: 10.1212/wnl.0000000000012896] [Citation(s) in RCA: 23] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2021] [Accepted: 09/20/2021] [Indexed: 01/05/2023] Open
Abstract
BACKGROUND AND OBJECTIVES There is accumulating evidence supporting an association between the thrombosis and thrombocytopenia syndrome (TTS) and adenovirus vector-based vaccines against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Yet TTS and TTS-associated cerebral venous sinus thrombosis (CVST) remain poorly characterized. We aim to systematically evaluate the proportion of CVST among TTS cases and assess its characteristics and outcomes. METHODS We performed a systematic review and meta-analysis of clinical trials, cohorts, case series, and registry-based studies with the aim to assess (1) the pooled mortality rate of CVST, TTS-associated CVST, and TTS and (2) the pooled proportion of patients with CVST among patients with any thrombotic event and TTS. Secondary outcomes comprised clinical characteristics of patients with postvaccination thrombotic event. This meta-analysis is reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and was written according to the Meta-analysis of Observational Studies in Epidemiology proposal. RESULTS Sixty-nine studies were included in the qualitative analysis comprising 370 patients with CVST out of 4,182 patients with any thrombotic event associated with SARS-CoV-2 vector-based vaccine administration. Twenty-three studies were included further in quantitative meta-analysis. Among TTS cases, the pooled proportion of CVST was 51% (95% confidence interval [CI] 36%-66%; I 2 = 61%). TTS was independently associated with a higher likelihood of CVST when compared to patients without TTS with thrombotic events after vaccination (odds ratio 13.8; 95% CI 2.0-97.3; I 2 = 78%). The pooled mortality rates of TTS and TTS-associated CVST were 28% (95% CI 21%-36%) and 38% (95% CI 27%-49%), respectively. Thrombotic complications developed within 2 weeks of exposure to vector-based SARS-CoV-2 vaccines (mean interval 10 days; 95% CI 8-12) and affected predominantly women (69%; 95% CI 60%-77%) under age 45, even in the absence of prothrombotic risk factors. DISCUSSION Approximately half of patients with TTS present with CVST; almost one-third of patients with TTS do not survive. Further research is required to identify independent predictors of TTS following adenovirus vector-based vaccination. REGISTRATION INFORMATION The prespecified study protocol has been registered in the International Prospective Register of Ongoing Systematic Reviews PROSPERO (CRD42021250709).

Abstract
BACKGROUND Fibromyalgia (FM) and generalized anxiety disorder (GAD) share common clinical features: they both affect women more than men, their diagnosis is based solely on clinical criteria, and some of the symptoms such as anxiety, aches and muscle tension, sleep disorders, and cognitive dysfunction occur in both diseases. For both conditions, an underlying dysregulation of the autonomic nervous system (ANS) has been proposed. OBJECTIVE The aims of this study were to investigate ANS dysfunction in FM and GAD and compare them with controls. METHODS Sympathetic skin response (SSR) from palm and sole and cross-sectional area (CSA) of bilateral vagus nerves (VN) were measured in 28 healthy controls, 21 FM patients, and 24 GAD patients. RESULTS CSA of VN was significantly smaller in FM patients (right: 1.97 ± 0.74mm2, left: 1.75 ± 0.65 mm2) and GAD patients (right: 2.12 ± 0.97mm2, left: 1.71 ± 0.86 mm2) compared to controls (right: 3.21 ± 0.75 mm2, left: 2.65 ± 1.13 mm2, p < 0.001, but did not differ between the two patient groups. SSR parameters were similar between patients and controls. SSR latency correlated to clinical scales (FM Widespread Pain Index) in the FM group (r = 0.515, p = 0.02 and r = 0.447, p = 0.05) for the upper and lower limbs respectively, but no other correlation between clinical and neurophysiological parameters was identified. CONCLUSION This study confirms similar ANS abnormalities in FM and GAD that fairly distinguish them from controls and support the hypothesis of a common pathophysiological substrate underlying both conditions.

Abstract
This longitudinal study aimed to investigate the predictive factors of suicidal ideation during the second lockdown in Greece. The respondents presented a 4.32% suicidal ideation in the second lockdown, which did not differ significantly to the initial 4.81%. Anxiety, depression, suicidal ideation during the first lockdown and living with a person with frail health and vulnerable for COVID-19 severe infection emerged as significant risk factors for suicidal ideation during the second lockdown, after controlling for gender, age, and mental health history. Depression was found as the only significant prognostic factor for suicidal ideation incidence of the second lockdown.

Abstract
BACKGROUND/AIM The aim of this study was to investigate psychometric indices and their association with electrodiagnostic studies (EDX). PATIENTS AND METHODS A total of 100 patients referred for EDX testing of the upper limbs were prospectively enrolled. Demographic data, laboratory test results, referral physician specialty, main symptom, WHODAS 2.0-12 item version, Hospital Anxiety and Depression Scale (HADS), Boston Carpal Tunnel Questionnaire (BCTQ) and a Numeric Rating Scale (NRS) indicating the extent of their discomfort were collected. RESULTS Normal EDX results were elicited from 56% of patients. Only the presence of numbness in the right hand, pain in the left hand and older age were significantly associated with an abnormal EDX result. The more depressed and anxious the patients were, the more they scored on psychometric scales. CONCLUSION The large prevalence of normal EDX studies raises the issue of unnecessary referrals. A proportion of patients are referred only according to their reported symptoms. Psychological factors affect the way a person expresses physical discomfort, leading to unnecessary EDX referrals and inevitably with normal results.

Abstract
Childhood trauma (CT) is correlated with suicidality among patients with bipolar disorder (BD). However, it has not been adequately investigated if a third factor, for instance impulsivity, mediates the effect of CT on suicidality in BD. This study aimed to explore potential mediatory effects of impulsivity in the pathway from CT to suicidality in BD. CT was assessed with the Early Trauma Inventory Self Report-Short Form (ETI-SR-SF), impulsivity with the Barratt Impulsivity Scale-11 (BIS-11) while lifetime suicidality was investigated with the Suicidal Behaviors Questionnaire-Revised (SBQ-R). The effect of childhood trauma on suicidality and impulsivity as well as the effect of impulsivity on suicidality were examined with multiple linear regressions, including gender, age and diagnosis (BD-I, BD-II) as covariates. Structural equation models were built and path analyses were performed (with AMOS 25 software and using bootstrapping in 1000 samples) for the examination of the mediatory role of BIS-11 and its subtypes in the effect of childhood trauma and its subtypes on suicidality. We included 78 BD euthymic patients (60.3% female, 67.9% BD-I). ETI-SR-SF significantly predicted SBQ-R (p=0.004) and BIS-11 (p<0.001), while BIS-11 significantly predicted SBQ-R (p=0.001). In a model including ETI-SR-SF and BIS dimensions, only ETISR-SF physical abuse (p=0.012) and BIS attentional (p<0.001) subscales significantly predicted SBQ-R. In structural equation models, the indirect effect of childhood trauma on suicidality via impulsivity was significant (p=0.003) while the direct effect of childhood trauma on suicidality was non-significant (complete mediation of the effect of childhood trauma on suicidality via impulsivity). In specific, both the indirect effect of physical abuse on suicidality via attentional impulsivity (p=0.002) and the direct effect of physical abuse on suicidality (p=0.013) were statistically significant (partial mediation of the effect of physical abuse on suicidality via attentional impulsivity). Childhood trauma predicts suicidality and impulsivity, while impulsivity predicts suicidality. More specifically, physical abuse and attentional impulsivity predict suicidality. The mediatory role of impulsivity completely explained the effect of childhood trauma on suicidality. Moreover, attentional impulsivity partially mediated the effect of physical abuse on suicidality. Therefore, management of impulsivity and especially of attentional impulsivity is crucial for the prevention and management of suicidality among BD patients with a history of childhood trauma.

Abstract
PURPOSE Resilience can be defined as the ability to maintain health in the face of adversity. Resilience has been associated with personality traits. Personality traits in the context of Eating Disorders (ED) have also been examined. However, the relationship between resilience and personality profile in patients with ED has not been studied. The aim of this study is to investigate whether personality dimensions impact on resilience, in patients with ED, compared to healthy participants. METHODS Connor and Davidson resilience scale, as a measure of resilience and temperament-character inventory, as a measure of personality dimensions, were completed by 100 participants: 50 (50%) healthy University students (controls subgroup) and 50 (50%) patients with ED, matched on age and gender. RESULTS Patients with ED showed lower resilience than healthy participants and scored higher on harm avoidance, and lower on reward dependence, self-directedness and cooperativeness than controls. Lower harm avoidance, higher persistence and higher self-directedness were associated with resilience in both subgroups. Self-directedness and persistence predicted resilience in both subgroups. Only Harm Avoidance predicted resilience in patients' subgroup. CONCLUSION To our knowledge, there are no existing data examining the effect of personality dimensions in resilience, in the context of ED. We found that only the effect of Harm Avoidance in resilience was different among the participants' subgroups. In conclusion, Harm Avoidance could explain differences in resilience between healthy participants and patients with ED. LEVEL OF EVIDENCE Level III: case-control analytic study.

Abstract
The original English language Empathy Quotient (EQ) is a self-reporting questionnaire that measures the construct of empathy in adults of normal intelligence. The EQ is sensitive to gender, and neurodevelopmental disorders. The EQ has been translated to many languages all over the world. The EQ - Greek version may be available through open access from www.autismresearchcentre.com. Aim of the present study was to validate the EQ- Greek version.The study took place in the 1st and 2nd Departments of Psychiatry of the National and Kapodistrian University of Athens (NKUA), "Eginition" and "Attikon" Hospitals respectively, and in the Korydallos Prison Psychiatric Clinic in Athens. Two groups completed the original 60 items version. One group consisted of general population and volunteer students from post graduate training programs (normal control group, N= 127) and the other group of patients recruited from the Adult Neurodevelopmental Disorders Unit of the 1st Department of Psychiatry of NKUA, the outpatients' clinic of the 2nd Department of Psychiatry of NKUA and the Korydallos Prison Psychiatric Clinic (patient group, N=196). Three versions of the EQ were examined: the EQ-40, EQ-28 and EQ-15. All versions showed very good internal validity: Cronbach's a value was 0.902, 0.892 and 0.793 respectively. They all showed good test-retest variability: the Intraclass Correlation Coefficient was 0.928, 0.924 and 0.855 respectively. Concurrent validity examined by the correlation analysis with the Interpersonal Reactivity Index (IRI) showed non-significant correlations between the EQ and the IRI. Exploratory Factor Analysis (EFA) indicated a one-factor structure for the three versions. Confirmatory Factor Analysis (CFA) for the one-factor structure showed a good fit for all the three versions. CFA for the three-factor structures (Cognitive Empathy, Emotional Empathy, Social Skills) showed also a good fit for EQ-28 and the EQ-15. When the EQ-40 was used as a measure of empathy in a single dimension in adults, the EQ discriminated the normal control group from the patients' group. The mean EQ score for the total sample was 35.84 with the lowest scoring being among Autism Spectrum Disorder (ASD) patients. As expected, females scored higher than males (p<0.001). To conclude, the Greek version of EQ showed good psychometric properties and could serve as a useful tool for clinicians to assess empathy in clinical populations and especially in subjects with ASD and other neurodevelopmental disorders.

Abstract
Background and purpose Mounting evidence supports an association between Guillain−Barré syndrome spectrum (GBSs) and severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) infection. However, GBSs in the setting of coronavirus disease 2019 (COVID‐19) remains poorly characterized, whilst GBSs prevalence amongst COVID‐19 patients has not been previously systematically evaluated using a meta‐analytical approach. Methods A systematic review and meta‐analysis of observational cohort and case series studies reporting on the occurrence, clinical characteristics and outcomes of patients with COVID‐19‐associated GBSs was performed. A random‐effects model was used to calculate pooled estimates and odds ratios (ORs) with corresponding 95% confidence intervals (CIs), compared to non‐COVID‐19, contemporary or historical GBSs patients. Results Eighteen eligible studies (11 cohorts, seven case series) were identified including a total of 136,746 COVID‐19 patients. Amongst COVID‐19 patients, including hospitalized and non‐hospitalized cases, the pooled GBSs prevalence was 0.15‰ (95% CI 0%–0.49‰; I2 = 96%). Compared with non‐infected contemporary or historical controls, patients with SARS‐CoV‐2 infection had increased odds for demyelinating GBSs subtypes (OR 3.27, 95% CI 1.32%–8.09%; I2 = 0%). In SARS‐CoV‐2‐infected patients, olfactory or concomitant cranial nerve involvement was noted in 41.4% (95% CI 3.5%–60.4%; I2 = 46%) and 42.8% (95% CI 32.8%–53%; I2 = 0%) of the patients, respectively. Clinical outcomes including in‐hospital mortality were comparable between COVID‐19 GBSs patients and non‐infected contemporary or historical GBSs controls. Conclusion GBSs prevalence was estimated at 15 cases per 100,000 SARS‐CoV‐2 infections. COVID‐19 appears to be associated with an increased likelihood of GBSs and with demyelinating GBSs variants in particular.

Abstract
IntroductionSuicide is the second most common cause of adolescent mortality worldwide.ObjectivesTo study the characteristics of a sample of adolescents (<18years of age) who died by suicide in Greece.MethodsWe investigated all suicides that took place within the area of the Piraeus Department of Forensic Medicine (population covered ~700,000) for the period 1992-2016, based on the victims’ forensic records.ResultsDuring the 25-year period, 16 adolescents (and 1162 adults) died by suicide. They were mostly males (11/68.75%) and of Greek Nationality (14/87.5%). The mean age was 15.56 years (range: 12-17, standard deviation: 1.46). Two (12.5%) were under psychiatric medication (an antipsychotic and an antidepressant, respectively); none was receiving a benzodiazepine or a mood-stabilizing antiepileptic. None had used amphetamine, cannabis, cocaine or heroin. Two (12.5%) -one girl one boy- had consumed alcohol. The suicides took place primarily at home (12/75%), followed by outdoors (3/18.75%); one (6.25%) took place in a correctional facility. Hanging was the most prevalent method (6/37.5), followed by jumping (5/31.25%), shooting by a firearm (2/12.5%), drowning (1/6.25%), medication overdose (1/6.25% -amitriptyline poisoning) and a case of suffocating death (1/6.25%). Most suicides happened in September (5/31.25%) and April (3/18.75%). No significant differences were noted with the adult sample.ConclusionsThe methods chosen by the adolescents who died by suicide in our sample differ strikingly from those of usual suicide attempts at that age (medication overdose/self-cutting). The periods when the suicides took place may imply a role for school stress. Our study was retrospective and focused primarily on a large urban area.

Abstract
Severe financial crises could influence a country's suicide trends and characteristics. We aimed to highlight differences among suicide completers before and after the onset of Greece's serious debt crisis of 2010 based exclusively on forensic data. The sample's size permitted a further elaboration by means of a time series analysis too. Data were collected from the Piraeus Department of Forensic Medicine for the period 1992-2016. We extracted information on sociodemographic parameters, psychiatric medication and alcohol intake, suicide method, place and month of suicide. The "after crisis onset" group (2011-2016) was significantly older (p = 0.039)-primarily due to differences in the 55-64 age group-, had more frequently used psychiatric medications (p < 0.001), less often alcohol (p = 0.001) and died more frequently by immolation (p = 0.001). These differences were-almost exclusively-due to changes regarding male suicidal behavior. Time series analysis indicates that no strong increasing trend in total (male + female) suicide count can be observed, despite a local increase in 2009-2010. Antidepressant-positive suicides show an increase after 2010, whereas alcohol-positive suicides show a decrease. Future predicted forecasts for antidepressant-positive suicides indicate a decrease (from 5.6 per year in 2018 to 4.3 per year in 2025) whereas an increase is predicted in alcohol-positive suicides (7.7 per year in 2017, 9.36 per year in 2025). Middle-aged men, compared to middle-aged women, presumably found it harder to adjust to economic hardship after the crisis onset. Finally, comparatively more men than women who died by suicide appear to have started and/or complied with psychiatric treatment after 2010.

Similar or Different Neuropsychological Profiles? Only Set Shifting Differentiates Women With Bipolar vs. Borderline Personality Disorder. Front Psychiatry 2021; 12:690808.

Abstract
There is ongoing debate about the similarities and differences between bipolar disorder (BD) and borderline personality disorder (BPD). Very few studies have concurrently assessed their neuropsychological profile and only on a narrow array of neuropsychological tests. We aimed to investigate the differences of these two patient groups on visual memory, executive function, and response inhibition. Twenty-nine BD patients, 27 BPD patients and 22 controls (all female) were directly compared on paired associates learning (PAL), set shifting (ID/ED), problem solving (SOC), and response inhibition (SSRT) using Cambridge Neuropsychological Test Automated Battery (CANTAB). Rank-normalized outcomes were contrasted in one-way ANOVA tests. Discriminant analysis was finally performed to predict BD or BPD patient status. BD patients performed significantly worse than controls on all tasks. BPD patients performed significantly worse than HC on all tests except SST. Significant differences between the two patient groups were recorded only on ID/ED, where BPD patients performed worse (p = 0.044). A forward stepwise discriminant analysis model based on ID/ED and SOC predicted correctly patients' group at 67.9% of cases. In conclusion, BD and BPD female patients appear to be more similar than different as regards their neuropsychological functions. This study is the first to show that BPD patients display more deficits than BD patients when directly compared on the set shifting executive function test, a marker of cognitive flexibility. Discerning BD from BPD patients through neuropsychological performance is promising but would improve by using additional subtler tests and psychometric evaluation.

Abstract
OBJECTIVES Control conditions' influence on effect estimates of active psychotherapeutic interventions for depression has not been fully elucidated. We used network meta-analysis to estimate the differences between control conditions. STUDY DESIGN AND SETTING We have conducted a comprehensive literature search of randomized trials of psychotherapies for adults with depression up to January 1, 2019 in four major databases (PubMed, PsycINFO, Embase, and Cochrane). The network meta-analysis included broadly conceived cognitive behavior therapies in comparison with the following control conditions: Waiting List (WL), No Treatment (NT), Pill Placebo (PillPlacebo), Psychological Placebo (PsycholPlacebo). RESULTS 123 studies with 12,596 participants were included. The I-squared was 55.9% (95% CI: 45.9%; to 64.0%) (moderate heterogeneity). The design-by-treatment global test of inconsistency was not significant (P = 0.44). Different control conditions led to different estimates of efficacy for the same intervention. WL appears to be the weakest control (odds ratio of response against NT = 1.93 (1.30 to 2.86), PsycholPlacebo = 2.03 (1.21 to 3.39), and PillPlacebo = 2.66 (1.45 to 4.89), respectively). CONCLUSIONS Different control conditions produce different effect estimates in psychotherapy randomized controlled trials for depression. WL was the weakest, followed by NT, PsycholPlacebo, and PillPlacebo in this order. When conducting meta-analyses of psychotherapy trials, different control conditions should not be lumped into a single group.

Abstract
OBJECTIVES Validated diagnostic interviews are required to classify depression status and estimate prevalence of disorder, but screening tools are often used instead. We used individual participant data meta-analysis to compare prevalence based on standard Hospital Anxiety and Depression Scale - depression subscale (HADS-D) cutoffs of ≥8 and ≥11 versus Structured Clinical Interview for DSM (SCID) major depression and determined if an alternative HADS-D cutoff could more accurately estimate prevalence. METHODS We searched Medline, Medline In-Process & Other Non-Indexed Citations via Ovid, PsycINFO, and Web of Science (inception-July 11, 2016) for studies comparing HADS-D scores to SCID major depression status. Pooled prevalence and pooled differences in prevalence for HADS-D cutoffs versus SCID major depression were estimated. RESULTS 6005 participants (689 SCID major depression cases) from 41 primary studies were included. Pooled prevalence was 24.5% (95% Confidence Interval (CI): 20.5%, 29.0%) for HADS-D ≥8, 10.7% (95% CI: 8.3%, 13.8%) for HADS-D ≥11, and 11.6% (95% CI: 9.2%, 14.6%) for SCID major depression. HADS-D ≥11 was closest to SCID major depression prevalence, but the 95% prediction interval for the difference that could be expected for HADS-D ≥11 versus SCID in a new study was -21.1% to 19.5%. CONCLUSIONS HADS-D ≥8 substantially overestimates depression prevalence. Of all possible cutoff thresholds, HADS-D ≥11 was closest to the SCID, but there was substantial heterogeneity in the difference between HADS-D ≥11 and SCID-based estimates. HADS-D should not be used as a substitute for a validated diagnostic interview.

Development and validation of the schedule for the assessment of insight in eating disorders (SAI-ED). Psychiatry Res 2020; 292:113308. [PMID: 32707219 DOI: 10.1016/j.psychres.2020.113308] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/16/2020] [Revised: 07/12/2020] [Accepted: 07/14/2020] [Indexed: 11/18/2022]
Abstract
This study examined the reliability, validity and internal structure of the newly developed, interview-based Schedule for the Assessment of Insight in Eating Disorders (SAI-ED) and the relationships of insight with demographic and clinical characteristics in EDs. Ninety-four female patients - 44 with anorexia nervosa (AN) and 50 with bulimia nervosa (BN) - were assessed with SAI-ED. The Brown Assessment of Beliefs Scale was used to evaluate convergent validity of SAI-ED. Hierarchical cluster analysis and multidimensional scaling were used to identify insight components and assess their inter-relationships. The final 8-item SAI-ED demonstrated good psychometric properties. Inter-rater and test-retest reliabilities were high. Three subscales of SAI-ED were identified which measure major insight components: awareness of illness, awareness of symptoms, and treatment engagement. Patients with AN had significant lower score on SAI-ED than patients with BN. Impaired insight was associated with: (a) lower current and lowest lifetime BMI and more severe dietary restrain in AN, (b) illness duration, severity of overall ED symptoms, body-related concerns and obsessionality in BN. Insight is a multidimensional construct in EDs associated with different clinical aspects in AN and BN. The SAI-ED is a valid and reliable tool for the assessment of insight in EDs patients.

The relationship between metacognitive beliefs and symptoms in eating disorders. PSYCHIATRIKE = PSYCHIATRIKI 2020; 31:225-235.

Abstract
The present study aimed to explore the role of dysfunctional metacognitive beliefs in Eating Disorders (EDs) and their potential associations with core and comorbid symptoms. The Metacognition Questionnaire-30 (MCQ-30), the Eating Disorder Examination Questionnaire 6.0 (EDE-Q), the Hospital Anxiety and Depression Scale (HADS) and the Maudsley Obsessive- Compulsive Inventory (MOCI) were used to evaluate 44 Anorexia Nervosa (AN), 50 Bulimia Nervosa (BN) patients and 37 controls. Patients featured more dysfunctional metacognitive beliefs which positively correlated with ED and comorbid symptoms. Both AN and BN patients had higher scores than healthy controls on MCQ-30 total score, Positive Beliefs about Worry, Negative Beliefs about Thoughts Uncontrollability and Danger and Need to Control Thoughts. AN patients also featured higher scores than healthy controls on Cognitive Self-Consciousness. No statistically significant difference was found between the two clinical groups in MCQ-30 total and subscale scores. Among metacognitive beliefs, Negative Beliefs about thoughts Uncontrollability and Danger showed the stronger correlations with core EDs symptoms, (coefficients ranging from 0.24 to 0.40), followed by Need to Control Thoughts (coefficients ranging from 0.22 to 0.38). Dysfunctional metacognitive beliefs were also significantly positively correlated with HADS-Anxiety, HADS-Depression and MOCI Total, in a similar manner. Dysfunctional metacognitive beliefs also predicted 19%, 35%, 20%, and 21% of the variance in Global EDE-Q, HADS-Anxiety, HADS-Depression and MOCI Total scores respectively, in regression analyses. Nevertheless, mediation analysis indicated that the relationship between Negative Beliefs about thoughts Uncontrollability and Danger and core EDs symptomatology as measured by EDE-Q, was not mediated by comorbid anxiety, depression and obsessionality. As a result, dysfunctions in metacognitive beliefs may reflect a common, trans-diagnostic path in AN and BN patients, towards a wide range of symptoms, both core and comorbid.

Abstract
Hoarding disorder is a debilitating condition that results from difficulty or inability to discard possessions and the need to save items and leads to cluttered living space. It impedes normal everyday functioning and causes significant distress and dysfunction. The aim of the current study was to validate the Greek version of the Saving Inventory-Revised (SI-R) in a non-clinical sample of 554 Greek adults. Factor structure and psychometric properties were investigated. Common exploratory (EFA) and confirmatory factor analysis (CFA) were used to explore the factor structure of the data. A three-factor solution was emerged for the Greek SI-R Which appears to cover the clinical dimensions of the phenomenon and consists of clutter, difficulty discarding and acquisition dimensions. This finding is in accordance with the original English version as well as other adaptations of the instrument in other languages. Some items cross loaded but such findings of cross loading items are also reported in related literature. The Greek version of the SI-R exhibits satisfactory internal consistency and good test retest reliability (stability). The current study also aimed to gather evidence towards the convergent and discriminant validity of Greek SI-R. Findings showed no correlation with measurements of different constructs such as anxiety, depression and non-hoarding obsessive compulsive symptoms but also only partial correlation with measurements of relative clinical constructs, such as hoarding items in obsessive compulsive inventories. Current findings suggest that the Greek SI-R can be a useful tool in the detection and evaluation of hoarding symptoms in Greek population.

Adipokines in anorexia nervosa: A systematic review and meta-analysis. Psychoneuroendocrinology 2020; 112:104485.

Abstract
OBJECTIVE The association between adipokine dysregulation and weight loss of patients with anorexia nervosa (AN) has been long investigated, in search of a causal relationship. We sought to: a) synthesize the available evidence on potential differences between AN patients and controls with regards to adipokine measurements (namely, leptin, adiponectin, resistin, soluble leptin receptor, visfatin, vaspin and omentin), b) estimate the potential differences between constitutionally thin (CT) subjects and AN patients, and c) present the available evidence with regards to biomarker efficacy of adipokines in AN. METHODS A structured literature search, last updated in 2/2019, was conducted in the following databases: MEDLINE, clinicaltrials.gov, PsycINFO, PSYNDEX and WHO Registry Network. The primary outcome was the standardized mean difference of each adipokine between AN patients and controls of normal BMI. Secondary outcomes included the correlation of leptin with BMI and bone mineral density among AN patients. The study protocol is published in PROSPERO (CRD42018116767). RESULTS In a total of 622 screened studies, after exclusion of non-relevant articles and duplicates, 84 reports on leptin, 31 reports on adiponectin, 12 on resistin, 10 on soluble leptin receptor, 5 on visfatin, 3 on vaspin and omentin were finally included in the meta-analysis. Publication bias assessment underlined the possibility of non-significant studies being underrepresented; still, significant heterogeneity renders this statement inconclusive. Leptin [ELISA: SMD (95% CI): -3.03 (-4, -2.06)], radioimmunoassay [RIA: -3.84 (-4.71, -2.98)] and resistin [-1.67 (-2.85, -0.48)] were significantly lower in patients with AN compared with controls, whereas visfatin decrease did not reach significance (-2.03 (-4.38, 0.3). Mean adiponectin, vaspin and soluble leptin receptor levels were significantly higher. In subgroup analysis, a significantly attenuated SMD was reported in ELISA studies compared with RIA studies. Leptin was significantly lower in AN patients compared to CT subjects and BMI marginally did not appear to confound the result. In all analyses, except for the correlation of leptin with BMI in AN patients, high heterogeneity was present. Meta-regression analysis indicated a potential confounding action of controls' BMI and age on leptin SMD and between-assay differences. Publication bias assessment underlined the possibility of nonsignificant studies being underrepresented; still, further investigation did not corroborate this and significant heterogeneity renders this statement inconclusive. CONCLUSION A distinct profile of adipokine dysregulation is apparent in AN patients, following the anticipated pattern of low BMI. A precise estimation of the magnitude is hindered by heterogeneity, partly caused by varying assays and methodologies. Interestingly, while mean leptin levels are lower in AN subjects compared with constitutionally thin women, there is an overlap in individual levels between the two groups and therefore, they cannot be used to differentiate between these states.

Probability of major depression diagnostic classification based on the SCID, CIDI and MINI diagnostic interviews controlling for Hospital Anxiety and Depression Scale - Depression subscale scores: An individual participant data meta-analysis of 73 primary studies. J Psychosom Res 2020; 129:109892. [PMID: 31911325 DOI: 10.1016/j.jpsychores.2019.109892] [Citation(s) in RCA: 26] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/18/2019] [Revised: 12/10/2019] [Accepted: 12/11/2019] [Indexed: 02/01/2023]
Abstract
OBJECTIVE Two previous individual participant data meta-analyses (IPDMAs) found that different diagnostic interviews classify different proportions of people as having major depression overall or by symptom levels. We compared the odds of major depression classification across diagnostic interviews among studies that administered the Depression subscale of the Hospital Anxiety and Depression Scale (HADS-D). METHODS Data accrued for an IPDMA on HADS-D diagnostic accuracy were analysed. We fit binomial generalized linear mixed models to compare odds of major depression classification for the Structured Clinical Interview for DSM (SCID), Composite International Diagnostic Interview (CIDI), and Mini International Neuropsychiatric Interview (MINI), controlling for HADS-D scores and participant characteristics with and without an interaction term between interview and HADS-D scores. RESULTS There were 15,856 participants (1942 [12%] with major depression) from 73 studies, including 15,335 (97%) non-psychiatric medical patients, 164 (1%) partners of medical patients, and 357 (2%) healthy adults. The MINI (27 studies, 7345 participants, 1066 major depression cases) classified participants as having major depression more often than the CIDI (10 studies, 3023 participants, 269 cases) (adjusted odds ratio [aOR] = 1.70 (0.84, 3.43)) and the semi-structured SCID (36 studies, 5488 participants, 607 cases) (aOR = 1.52 (1.01, 2.30)). The odds ratio for major depression classification with the CIDI was less likely to increase as HADS-D scores increased than for the SCID (interaction aOR = 0.92 (0.88, 0.96)). CONCLUSION Compared to the SCID, the MINI may diagnose more participants as having major depression, and the CIDI may be less responsive to symptom severity.

Abstract
INTRODUCTION A specific clinically relevant staging model for schizophrenia has not yet been developed. The aim of the current study was to evaluate the factor structure of the PANSS and develop such a staging method. METHODS Twenty-nine centers from 25 countries contributed 2358 patients aged 37.21 ± 11.87 years with schizophrenia. Analysis of covariance, Exploratory Factor Analysis, Discriminant Function Analysis, and inspection of resultant plots were performed. RESULTS Exploratory Factor Analysis returned 5 factors explaining 59% of the variance (positive, negative, excitement/hostility, depression/anxiety, and neurocognition). The staging model included 4 main stages with substages that were predominantly characterized by a single domain of symptoms (stage 1: positive; stages 2a and 2b: excitement/hostility; stage 3a and 3b: depression/anxiety; stage 4a and 4b: neurocognition). There were no differences between sexes. The Discriminant Function Analysis developed an algorithm that correctly classified >85% of patients. DISCUSSION This study elaborates a 5-factor solution and a clinical staging method for patients with schizophrenia. It is the largest study to address these issues among patients who are more likely to remain affiliated with mental health services for prolonged periods of time.

Abstract
Contradictory findings have been reported regarding the association between self-esteem and aggression. Most studies have dealt with non-criminal populations. This study aimed to explore the relationship between self-esteem and aggression and investigate possible differences in self-esteem and aggression between female inmates and women without criminal records (non-criminals) in the prefecture of Attica, Greece. One hundred fifty-seven female inmates in the Attica's Korydallos Female Prison and 150 non-criminals from Attica's general population completed the Buss & Perry Aggression Questionnaire and Rosenberg's Self-esteem Scale between February 2012 and April 2014. Lower self-esteem was associated with higher aggression among women independent of criminality. Self-esteem was lower in inmates (Mean = 18.06, SD = 6.19) than in non-criminals (Mean = 21.65, SD = 4.90, p < .001). Female prisoners presented higher aggression than non-criminals (unadjusted Mean = 78.40, SD = 23.60 versus Mean = 68.82, SD = 14.95, p < .001). However, after adjusting for age, education and self-esteem, this difference was no longer statistically significant (p = .127). Further studies, especially in female offenders, should be conducted to broaden our understanding of female aggression with a view to developing and promoting focused therapeutic procedures.

Neutrophil-to-lymphocyte ratio in schizophrenia: A systematic review and meta-analysis. Schizophr Res 2019; 206:4-12.

Abstract
BACKGROUND The immune system appears to be dysregulated in schizophrenia (SZ). The potential prognostic or diagnostic value of neutrophil-to-lymphocyte ratio (NLR), an inexpensive proxy marker for a wide spectrum of conditions, has not been established in SZ. We seek to investigate a) whether NLR is increased in SZ patients, b) if this difference in more prominent in relapsed SZ or first-episode psychosis. METHODS A structured algorithm was applied in MEDLINE (1946-2018), PsychInfo, Scopus, Cochrane Central Register of Controlled Trials (CENTRAL) (1999-2018), PSYNDEX (1984-2017) and Clinicaltrials.gov (2008-2018) databases. RESULTS Through the database search, 1023 articles were screened. Ten studies (804 SZ patients, 671 controls) were included in the meta-analysis. In SZ patients, the NLR was increased by 0.65 (95% CI: 0.54, 0.86, p < 10-5). This difference was significant in both acute relapse and first-episode psychosis subgroups. Studies of moderate and high quality also showed a significant NLR increase in SZ patients (I2 = 0%). Meta-regression analysis showed that the polymorphonuclear count and antipsychotic use may confound the result. In leave-one-out meta-analysis, no study altered the significance of the result when omitted. CONCLUSIONS NLR in SZ patients is increased, both in chronic disease and in first-episode psychosis. Baseline characteristics, such as polymorphonuclear count and antipsychotic use, may affect its accuracy. The application of this marker in clinical practice requires the description of its normal values in the general population, its potential change after antipsychotic administration and its correlation with disease activity. A large-scale, prospective study design would resolve these issues.

Abstract
BACKGROUND/AIM To evaluate psychometric properties of the Connor and Davidson Resilience Scale (CD-RISC) in a Greek population. MATERIALS AND METHODS Internal consistency and test-retest reliability were measured. Global Assessment of Functioning Scale (GAF), World Health Organization Quality of Life (WHOQOL) questionnaire, Perceived Stress Scale (PSS) and General Health Questionnaire (GHQ) were used as measures for convergent reliability. Factors were extracted by using exploratory factor analysis (EFA). A total of 546 subjects (244 healthy individuals and 302 psychiatric patients) were recruited. RESULTS The scale showed excellent internal consistency (Cronbach's alpha=0.925), as well as excellent test-retest reliability (intra-class correlation coefficient=0.925). CD-RISC scores were positively correlated to GAF and WHOQOL scores, while being negatively correlated to PSS and GHQ scores, establishing adequate convergent validity. We decided on a model with four factors, in order to form sub-scales that measure different, but related aspects of resilience. CONCLUSION CD-RISC is a reliable and valid measure of resilience and can be used for clinical and research aims in the Greek population.

Abstract
Bipolar disorder is associated with neurocognitive impairment but the etiology of such impairment remains largely unknown. The present study aimed at investigating the performance of bipolar patients in various neuropsychological tasks within the framework of HPA axis hyperactivity model and also the impact of disease characteristics on neuropsychological functioning. Cognitive performance of 60 bipolar-I patients and 30 healthy controls was evaluated by using tasks from the CANTAB battery targeting visual memory, executive function and inhibitory control. Current symptoms were evaluated via administration of the Hamilton Depression Rating Scale (HAMD) and Young Mania Rating Scale (YMRS) whereas assessment of functioning was performed with the Global Assessment of Functioning (GAF). Basal cortisol levels were determined and all patients were administered the Dexamethasone Suppression Test (DST). Statistically significant differences between patients and controls were found in visuo-spatial associative learning and memory, planning, attentional set shifting and inhibitory control. Worse performance in visuospatial associative memory correlated with longer duration of illness and higher levels of basal cortisol. Poorer attentional set shifting was related to higher number of manic episodes. We found no relationship of neurocognitive measures with DST suppression status, current symptom severity or history of psychosis. The results of our study confirm the presence of cognitive deficits in bipolar disorder and provide evidence on the relation of cortisol with neuropsychological functioning, especially visuo-spatial associative memory. Moreover, we have found that number of previous manic episodes and duration of illness is associated with worse cognitive performance. It is known that neurocognitive deficits are evident in many patients with bipolar disorder. These deficits are often a cause of considerable distress and can lead to impairment of psychosocial and occupational functioning. The role of HPA axis needs to be further examined in bipolar disorder. Nevertheless, the identification of factors affecting neurocognitive functioning, like basal cortisol and number of manic episodes, may contribute to the implementation of more appropriate prevention strategies.

Narcissism but Not Criminality Is Associated With Aggression in Women: A Study Among Female Prisoners and Women Without a Criminal Record. Front Psychiatry 2019; 10:21.

Abstract
Aggression has drawn research attention during the past decades. It remains unclear how self-esteem, self-perception, narcissism and certain socio-demographic factors impact the course of aggression. Female aggression is considered to differ in its origins and is understudied. Only few studies have attempted to examine the aforementioned variables among females, while none of them included a comparison between delinquent and non-delinquent individuals. The present study examines the effect of self-esteem, self-perception, narcissism, and socio-demographic factors on aggression among female inmates and women without criminal record (non-delinquents). One hundred fifty-seven female inmates in the Attica's Korydallos Female Prison and 150 women with no criminal record were assessed with Buss & Perry Aggression Questionnaire, Rosenberg's Self-esteem Scale, Narcissistic Personality Inventory-40 and the Self-Perception Profile for Adults. When inmates were compared to non-delinquent women, it emerged that higher aggression could be independently predicted by higher levels of narcissistic personality traits and sociability, as well as lower age, lower education, lower self-esteem, and lower levels of self-perception items including nurturance, job competence and athletic abilities. Aggression was not predicted by the participants' group (inmates vs. non-delinquents). Within female inmates, independently of the type of their offense (convicted for violent vs. non-violent crimes), it was found that lower job competence, higher narcissistic personality traits and a history of childhood maltreatment could predict higher aggression. Our results support the notion that female aggression differs from male and highlight the significant parameters that may predict aggression either among women (inmates and non-delinquent women) or among female inmates (violent or non-violent crimes). It is the presence of narcissistic traits which predict aggression rather than criminality in general, including violent and non-violent crimes.

Abstract
This study aimed to assess hopelessness in 170 hospitalized individuals with recent suicide attempt and examine its association with patients' characteristics, with a view to improving awareness in health professionals and especially nurses, who are among the first to take care of these patients. Participants completed Beck Hopelessness Scale and Beck Depression Inventory. More than half (51.18%) experienced moderate-to-severe hopelessness. A multiple linear regression analysis showed that age, attempted suicide method, past suicide attempt, and psychiatric diagnosis contributed statistically significantly to hopelessness prediction. Hopelessness assessment could efficiently help health professionals to minimize both inpatient suicide and suicidal acts after discharge.

Abstract
Previous literature shows an association between several psychosocial factors or life events in general and delinquency. Factors such as gender, cannabis and drugs use are firmly connected to delinquency. Similarly, interpersonal violent behavior appears to be more frequent in people with lower socioeconomic status and people with lower education. The association of these factors with the violent or non-violent crimes, especially in Greek research literature, is very limited. The present study is an attempt to examine in a Greek prison population the correlation of demographic and psychosocial factors with violent and non-violent crime. The prison population sample comprised of 308 males from a total of 1300 prisoners, aged between 18 and 77 years old. The survey was conducted from January 2012 until August 2013 in Korydallos and Domokos prisons. In our prison population sample most of the crimes were non-violent. The prisoners were urban dwellers, of young age, were not married and were in short-term relationships on average. They had completed their military obligations, were not live alone, and have been working in the last six months before being imprisoned, in manual labor. They had low-grade education and poor school achievements, had been brawling with classmates and had history of antisocial behavior (liked to "put fire" and abuse animals). They report good relationships with their parents; however, they had experienced violence in parental relationships and some kind of violence, mainly by the father and secondarily by the mother. They have not been involved in gangs necessarily and have a history from a young age, of alcohol, cannabis and drugs use. Cannabis use history was reported by 208 prisoners (67.5%) and 133 (63.9%) of them started using at the age of 10-15 years old. A total of 179 prisoners (58.5%) reported a history of drug use, about half of them (50.3%) reported being addicted to a combination of drugs. For 40.8% (n=73) drug use was initiated in the age of 10-15 years old, while the largest percentage (46.4%) of prisoners mentioned as starting age 16-20 years old. Although the above features underline the great differences between prison population and the general population, there are no significant associations of these factors with violent or non-violent crime. However, the prisoners with drug use history were 65% less likely to have been sentenced for violent crime. Also, the prisoners exempted from their military duties, were 49% less likely to have committed violent crime.

Association of Schizoid and Schizotypal Personality disorder with violent crimes and homicides in Greek prisons. Ann Gen Psychiatry 2018; 17:35. [PMID: 30116288 PMCID: PMC6086037 DOI: 10.1186/s12991-018-0204-4] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/07/2018] [Accepted: 07/31/2018] [Indexed: 01/05/2023] Open
Abstract
BACKGROUND Personality disorders (PDs) have been associated with both violent crimes and homicides in many studies. The proportion of PDs among prisoners reaches up to 80%. For male prisoners, the most common PD in the literature is antisocial PD. The aim of this study was to investigate the association between PDs and violent crimes/homicides of male prisoners in Greece. METHODS A sample of 308 subjects was randomly selected from a population of 1300 male prisoners incarcerated in two Greek prisons, one urban and one rural. The presence of PDs was assessed using the Mini International Neuropsychiatric Interview (MINI) and the Personality Diagnostic Questionnaire-4 (PDQ-4). Using logistic regression models PD types and PD "Clusters" (independent variables) were associated with "violent/non-violent crimes" and "homicides/non homicides" (dependent variables). RESULTS "Cluster A" PDs (Paranoid, Schizoid, and Schizotypal) were diagnosed in 16.2%, "Cluster B" (Antisocial, Borderline, Histrionic, Narcissistic) in 66.9% and "Cluster C" (Obsessive-Compulsive, Dependent, Avoidant) in 2.9% of the studied population. Violent crimes and homicides were found significantly associated with "Cluster A" PDs (p = 0.022, p = 0.020). The odds ratio of committing violent crimes was 2.86 times higher for patients with "Cluster A" PDs than the ones without PDs. In addition, the odds ratio of committing homicides was 4.25 times higher for patients with "Cluster A" PDs. In separate analyses, the commitment of violent crimes as well as homicides, was significantly associated with Schizoid (p = 0.043, p = 0.020) and Schizotypal PD (p = 0.017, p = 0.030). CONCLUSIONS The majority of prisoners was found to suffer from a PD, mainly the Antisocial "Cluster B", but the commitment of violent crimes and homicides was significantly associated only with "Cluster A" PDs and specifically with Schizoid and Schizotypal PD.

Abstract
Schema therapy (ST) is an integrative therapy, which combines elements of cognitive behavior therapy, attachment theory, object relations theory and emotional-focused models. Schema therapy is an effective treatment for patients with personality disorders and other chronic psychological disorders. Early Maladaptive Schemas (EMSs) are a main concept in schema theory referring to self-defeating, core themes or patterns. They develop as a result of traumatic or toxic childhood experiences and the frustration of the core emotional needs in childhood. To date 18 EMSs have been identified and grouped into five higher order structures, known as domains. For the evaluation of the EMSs, Young developed a self-report inventory, the Young Schema Questionnaire (YSQ). There are two forms of the YSQ, the Young Schema Questionnaire - Long Form 3 (YSQ-L3) a 232-item inventory and the Young Schema Questionnaire - Short form 3 (YSQ-S3), a 90-item inventory, which is a subset of the Long form. The aim of this study was to validate the Greek Version of the YSQ-S3. A non-clinical sample of 1,236 undergraduate students completed the YSQ-S3 and 124 patients with Axis-I, Axis II or comorbid diagnosis, completed the YSQ-L3. Moreover, both samples completed the second part of the Adults Self Report (ASR). Internal consistency reliability, discriminative, convergent and predictive validity were examined. The internal consistency reliability of the schema factors was satisfactory with a Cronbach's alpha coefficient of 0.70 or above, for all factors in both student's and clinical sample. The effect sizes were high for most of the scales, regarding the differences between clinical and non-clinical sample. Emotional Deprivation, Vulnerability to harm or Illness, Subjugation, Social Isolation/Alienation and Defectiveness/Shame had the highest effect sizes in the clinical sample and in the non-clinical sample according to whether they had ever visited a mental health specialist. This may suggest that these EMSs are more sensitive and useful markers of psychological problems. In addition, patients with Axis II pathology scored significantly higher on Emotional Deprivation, Abandonment, Mistrust/Abuse, Social Isolation/Alienation compared to patients with only Axis I pathology. This finding is consistent with Schema theory, as these EMSs are associated with earlier in life traumatic experiences and insecure attachment and lie in the core of personality pathology. YSQ-S3 factors were significantly correlated with all ASR dimension and linear regression analysis showed that certain EMSs could predict Depressive and Anxiety problems. In total, the greek version of the YSQ-S3 showed good reliability and validity.

Abstract
Hoarding disorder is characterized by difficulty discarding or parting with possessions regardless their actual value as well as, in most cases, persistent acquisition of objects. Possessions are accumulated in large numbers that fill up and clutter active living space to the extent that its intended use is no longer possible resulting to significant functional impairment and/or distress. Saving and difficulty discarding appear to be associated to subjective beliefs about the instrumental, sentimental or intrinsic value of objects. Despite significant impact on the individual, the family and the community, until recently hoarding disorder had been a "neglected" clinical phenomenon. The recent research efforts to study and understand this phenomenon led to significant changes regarding the diagnostic status and therapeutic interventions. It was classified as a distinct diagnostic entity in the recent edition of the Diagnostic and Statistical Manual of Mental Disorders of the American Psychiatric Association-5th ed. (DSM-5). Hoarding is not considered a symptom of obsessive compulsive disorder or obsessive compulsive personality disorder anymore and it is now ranked among compulsive spectrum disorders. So far the cognitive model for hoarding disorder is the main, widely accepted, clinically and empirically supported theoretical framework for understanding its features. The cognitive model offers an explanation about the predisposing, onset and perpetuating factors of the disorder as well as the basis for the development of specific therapeutic interventions. The cognitive model conceptualizes hoarding disorder as a result of four factors: personal vulnerability (heredity, early experiences and life events, personality traits, interpersonal difficulties), difficulties in information processing (deficits in attention, memory, executive functions such as decision making and categorization), maladaptive cognitive content (meaning of possessions, emotional attachment to possessions, dysfunctional beliefs in relation to the mnemonic ability and memory importance) through which hoarding behaviors are reinforced and finally installed (positive and negative reinforcement, association with positive or negative emotions e.g. pleasure in relation to acquisition/saving and anxiety or discomfort in relation to discarding). The purpose of this article is to inform about this new disorder giving emphasis on recent data in regard to its phenomenology and provide a detailed description of the cognitive model. Finally, a brief mention on the psychotherapeutic and pharmacological interventions is presented. Hoarding Disorder is a difficult clinical problem to treat. Poor insight, ego-syntonic nature of symptoms and treatment resistance are often reported in patients. Further improvement of the therapeutic interventions in order to improve effectiveness and target the high rate of treatment drop out is needed.

Abstract
We studied a sample of suicide victims from Greece's main port of Piraeus area (population: approx. 700,000 individuals) and investigated all suicides for the 10-year period 2006-2015, collecting data from the victims' forensic records at the Piraeus Department of Forensic Medicine. Sixty-nine (15.9%) out of 435 suicides were due to drowning, 51 (73.9%) males and 18 (26.1%) females. Drowning was the third most common suicide method with most in the sea (92.8%), fewer in wells (7.2%). Median age: males 52.2 years (standard deviation (SD): 20.3, range: 27-89) and females 58.8 years (SD: 15.2, range: 32-84). Psychiatric medications: antidepressants (6 cases, 8.9%), benzodiazepines (6 cases, 8.9%) and antipsychotics (1 case, 1.5%). Other substances: alcohol (14 cases, 20.9%), cocaine (1 case, 1.5%) and opioids (1 case, 1.5%). No seasonal effect was observed for suicides by drowning. Greece, being a country with an embracing coastline, could provide a field of study for suicide by drowning.

Psychotic (delusional) depression and completed suicide: a systematic review and meta-analysis. Ann Gen Psychiatry 2018; 17:39.

Abstract
BACKGROUND It remains unclear whether psychotic features increase the risk of completed suicides in unipolar depression. The present systematic review coupled with a meta-analysis attempts to elucidate whether unipolar psychotic major depression (PMD) compared to non-PMD presents higher rates of suicides. METHODS A systematic search was conducted in Scopus, PubMed, and "gray literature" for all studies providing data on completed suicides in PMD compared to non-PMD, and the findings were then subjected to meta-analysis. All articles were independently extracted by two authors using predefined data fields. RESULTS Nine studies with 33,873 patients, among them 828 suicides, met our inclusion criteria. PMD compared to non-PMD presented a higher lifetime risk of completed suicides with fixed-effect pooled OR 1.21 (95% CI 1.04-1.40). In a sub-analysis excluding a very large study (weight = 86.62%), and comparing 681 PMD to 2106 non-PMD patients, an even higher pooled OR was found [fixed-effect OR 1.69 (95% CI 1.16-2.45)]. Our meta-analysis may provide evidence that the presence of psychosis increases the risk of suicide in patients suffering from severe depression. The data are inconclusive on the contribution of age, mood congruence, comorbidity, and suicide method on PMD's suicide risk. The lack of accurate diagnosis at the time of suicide, PMD's diagnostic instability, and the use of ICD-10 criteria constitute the main study limitations. CONCLUSIONS The presence of psychosis in major depression should alert clinicians for the increased risk of completed suicide. Thus, the implementation of an effective treatment both for psychotic depression and patients' suicidality constitutes a supreme priority.
