Abstract
The severity of the pandemic and its consequences on health and social care systems were quite diverse and devastating. COVID-19 was associated with an increased risk of neurological and neuropsychiatric disorders after SARS-CoV-2 infection. We did a cross-sectional study of 3 months post-COVID consequences of 178 Cuban subjects. Our study has a unique CUBAN COVID-19 cohort of hospitalized COVID-19 patients and healthy subjects. We constructed a latent variable for pre-health conditions (PHC) through Item Response Theory (IRT) and for post-COVID neuropsychiatric symptoms (Post-COVID-NPS) through Factor Analysis (FA). There seems to be a potential causal relationship between determinants of CIBD and post-COVID-NPS in hospitalized COVID-19 patients. The causal relationships accessed by Structural Equation Modeling (SEM) revealed that PHC (p < 0.001) and pre-COVID cognitive impairments (p < 0.001) affect the severity of COVID-19 patients. The severity of COVID-19 eventually results in enhanced post-COVID-NPS (p < 0.001), even after adjusting for confounders (age, sex, and pre-COVID-NPS). The highest loadings in PHC were for cardiovascular diseases, immunological disorders, high blood pressure, and diabetes. On the other hand, sex (p < 0.001) and pre-COVID-NPS including neuroticism (p < 0.001), psychosis (p = 0.005), cognition (p = 0.036), and addiction (p < 0.001) were significantly associated with post-COVID-NPS. The most common neuropsychiatric symptom with the highest loadings includes pain, fatigue syndrome, autonomic dysfunctionalities, cardiovascular disorders, and neurological symptoms. Compared to healthy people, COVID-19 patients with pre-health comorbidities or pre-neuropsychiatric conditions will have a high risk of getting severe COVID-19 and long-term post-COVID neuropsychiatric consequences. Our study provides substantial evidence to highlight the need for a complete neuropsychiatric follow-up on COVID-19 patients (with severe illness) and survivors (asymptomatic patients who recovered).

Abstract
ABSTRACT The present study aimed to examine the cross-sectional association between attachment style and self-reported disturbed self-awareness (disturbed sense of mineness of experiences) and depersonalization (disturbed sense of first-person perspective) in patients with psychotic disorders, unaffected siblings, and healthy controls. Data pertain to a subsample of the GROUP (Genetic Risk and Outcome of Psychosis) study. We found positive associations between anxious attachment and disturbed self-awareness and depersonalization across participants with different psychosis vulnerability. We also found a positive association between avoidant attachment and depersonalization, although on a trend level. Findings indicate that attachment style is associated with self-reported disturbed self-awareness and depersonalization over and above the influence of psychotic or depressive experiences in people across the vulnerability spectrum of psychosis. This supports the importance of attachment style, self-awareness, and depersonalization as potential targets in prevention and treatment interventions in patients with psychotic disorders or those with increased vulnerability.

Abstract
BACKGROUND Anxiety disorders affect blood pressure both during the day and at night. Little is known about the effect of individual anxiety disorders on the circadian rhythm of blood pressure. OBJECTIVES The purpose of this study is to compare the nocturnal drop in blood pressure in patients with panic disorder (PD), generalized anxiety disorder (GAD), and healthy individuals. METHODS The study was conducted on fifty consecutive outpatients with anxiety disorders and personality disorders who participated in intensive group psychotherapy. Diagnoses were made according to DSM-IV-TR criteria using the PSE-10 questionnaire. Out of 50 patients under study, 17 were diagnosed with PD and 21 with GAD. The control group consisted of 40 healthy people recruited in the course of other studies. The resulting three groups were compared in terms of circadian blood pressure using the ABPM method. RESULTS Mean nocturnal falls in systolic and diastolic blood pressure were the following: 2% and 3% (PD), 11% and 12% (GAD), 27% and 23% (control). Four people out of PD group had higher systolic and diastolic blood pressure at night than during the day. The ratios between non-dippers/dippers were: 0/15 (PD), 8/21 (38% - GAD) and 40/40 (100% - control). CONCLUSIONS The patients with PD were characterized by an almost flat course of circadian blood pressure. The patients with GAD had a lower mean nocturnal fall in blood pressure than the control group, but significantly higher than the patients with PD. The differences in the circadian course of blood pressure between PD and GAD are so large that the impact of these disorders should be investigated separately.

Abstract
BACKGROUND Substance use is overrepresented in patients with psychosis. Maladaptive coping has been proposed as one of the mechanisms which might underlie this high prevalence. Patients are known to apply more maladaptive coping compared to the healthy population. However, it is unknown whether coping is associated with the use of different substances across those with different vulnerability for psychosis, and whether coping mediates the possible association between life events and substance use. METHODS In this multicenter, cohort study, 429 patients, 504 siblings, and 220 controls were included. We determined whether coping was associated with tobacco smoking, cannabis use, or alcohol consumption. Multivariable logistic regression models were applied whilst correcting for potential confounders. We performed post-hoc analyses to explore the association between negative life events, tobacco smoking, and the role of coping as a mediator in patients with psychosis. RESULTS A positive association was found in patients between passive coping and tobacco smoking (fully adjusted OR 1.65, 95% CI 1.18-2.31). Tobacco smoking patients experienced more negative life events compared to non-smoking patients and passive coping mediated this association. In siblings and controls, none of the coping strategies were associated with substance use. CONCLUSIONS The coping style of patients with psychosis is associated with tobacco smoking and mediates the association between negative events and tobacco smoking. No significant associations were found in siblings, controls or concerning other substance use. Future research is required to examine whether enhancing healthy coping strategies decreases tobacco use in patients with psychosis.

Abstract
INTRODUCTION The core symptoms of narcolepsy such as excessive daytime sleepiness and cataplexy are well known. However, there is mounting evidence for a much broader symptom spectrum, including psychiatric symptoms. Disordered sleep has previously been linked with dissociative symptoms, which may imply that patients with narcolepsy are more prone to develop such symptoms. OBJECTIVES To investigate the frequency of dissociative symptoms in adult patients with narcolepsy type 1 compared to population controls. METHODS In a retrospective case control study, sixty adult patients fulfilling the criteria for narcolepsy type 1 and 120 matched population control subjects received a structured interview using the Schedules for Clinical Assessment in Neuropsychiatry (SCAN) to assess dissociative symptoms and disorders. RESULTS A majority of narcolepsy patients reported dissociative symptoms, and even fulfilled the DSM-IV-TR criteria of a dissociative disorder (62% vs 1% in controls, p < .001). Most frequently reported symptoms were "dissociative amnesia" (37% vs 1%, p < .001) and "dissociative disorder of voluntary movement" (32% vs 1%, p < .001). CONCLUSION Dissociative symptoms are strikingly prevalent in adult patients with narcolepsy type 1. Although a formal diagnosis of dissociation disorder should not be made as the symptoms can be explained by narcolepsy as an underlying condition, the findings do illustrate the extent and severity of the dissociative symptoms. As for the pathophysiological mechanism, there may be symptom overlap between narcolepsy and dissociation disorder. However, there may also be a more direct link between disrupted sleep and dissociative symptoms. In either case, the high frequency of occurrence of dissociative symptoms should result in an active inquiry by doctors, to improve therapeutic management and guidance.

Abstract
This cross-sectional study examined the prevalence of PTSD with secondary psychotic symptoms (PTSD-SP), its comorbidities, and its association with torture and depression in treatment-seeking refugees. Data were pooled from the Danish Database on Refugees with Trauma (DART). The sample represents approximately 90% of trauma-affected refugee-patients (N = 627) attending a Danish psychiatric outpatient clinic from 2008 to 2013. PTSD, secondary psychotic symptoms, and comorbidities were assessed with structured and routine clinical interviews. The association of PTSD-SP with torture and depression was investigated using hierarchical logistic regression. The prevalence of PTSD-SP in treatment-seeking refugees with PTSD was 30%. Among these, 44% fulfilled the criteria for Enduring Personality Change After Catastrophic Experience (EPCACE). Psychotic symptoms comprised hallucinations and persecutory delusions, often reflecting trauma-related themes. Comorbidity with depression was high (79%). Neither torture, nor other war-trauma (ex-combatant, imprisonment, civilian war trauma) predicted PTSD-SP, but comorbid depression did. Depression only explained a small amount of the total PTSD-SP variance. Results indicate that PTSD-SP is common in treatment-seeking refugees. However, its etiology is poorly understood. This highlights the need for further research to improve diagnosis and treatment for this patient group.

Abstract
PURPOSE There is a paucity of data on heritability of psychotic disorders in Africa. The study aimed to investigate morbid risk of schizophrenia and mood disorder among first-degree relatives of schizophrenia probands, compared with mood disorder and healthy controls. METHODS The study examined 330 first-degree relatives of probands with schizophrenia (n = 50), 350 first-degree relatives of probands with mood disorder (n = 50) and 387 first-degree relatives of healthy control (n = 50). The Schedules for Clinical Assessment in Neuropsychiatry, SCAN was used to ascertain diagnosis in ill subjects. To each subject, a socio-demographic questionnaire was administered. Family history was obtained using the Family History Schedule. Morbid risk estimates were calculated using the Weinberg shorter method. RESULTS There was a significant difference between the mean age of relatives of schizophrenia probands compared to mood disorder (p = 0.01, 95 % CI 1.34-9.61) and healthy control (p < 0.01, 95 % CI 1.53-9.84). There were also significant differences between the number of children of schizophrenia probands and the number of children of normal control (p < 0.01, 95 % CI -2.0 to -3.9), as well as the number of deceased first-degree relatives of schizophrenia probands compared to normal control (p = 0.04, 95 % CI 0.01-0.94). Finally, there was a significant difference between the number of first-degree relatives of schizophrenia probands compared to the number of first-degree relatives of healthy control who were below the age of risk for schizophrenia (p = 0.01, 95 % CI -0.12 to -1.27). Morbid risks of 4.38 and 0.39 were obtained for schizophrenia among first-degree relatives of probands with schizophrenia and mood disorder, while first-degree relatives of probands with schizophrenia, mood disorder and healthy control had morbid risks for mood disorder of 0.42, 3.82 and 0.35, respectively. CONCLUSION The study revealed excess mortality among first-degree relatives of schizophrenia patients. First-degree relatives of probands with schizophrenia and mood disorder also had higher morbid risks for these psychotic conditions than healthy control with some measure of overlap between the two diagnostic categories.

Abstract
BACKGROUND Existing standardized diagnostic interviews are not used by psychiatrists in clinical settings. There is an urgent need for a clinician-administered tool for assessment of adult psychopathology that produces dimensional measures, in addition to categorical diagnoses. METHODS The Standard for Clinicians' Interview in Psychiatry (SCIP) was designed to be used in clinical settings and generates dimensional measures. The reliability of the SCIP was tested at six sites: one hospital and two clinics in USA, two hospitals in Egypt and one clinic in Canada. Participants were adult patients who were admitted for inpatient psychiatric treatment or came for regular office visits in the outpatient clinic. Refusal rate was <1%. Missing data were <1.1%. Patients with dementia, mental retardation or serious medical conditions were excluded. A total of 1,004 subjects were interviewed between 2000 and 2012. RESULTS Inter-rater reliability (Kappa) was measured for 150 SCIP items: 116 items (77.3%) had good reliability (Kappa>0.7), 28 items (18.7%) had fair reliability (Kappa ranges from 0.5 to 0.7) and six items (4%) had poor reliability (Kappa<0.5). Cronbach's alpha for internal consistency was measured for the SCIP dimensions: anxiety, posttraumatic stress, depression, mania, hallucinations, Schneider first-rank symptoms, delusions, disorganized thoughts, disorganized behavior, negative symptoms, alcohol addiction, drug addiction, attention and hyperactivity. All of the SCIP dimensions had substantial Cronbach's alpha values (>0.7) with the exception of disorganized thoughts (Cronbach's alpha=0.375). CONCLUSIONS The SCIP is a reliable tool for assessing psychological symptoms, signs and dimensions of the main psychiatric diagnoses.

Abstract
This prospective analysis aimed to study the influence of psychopathological dimensions on the global functioning of persons suffering from psychotic disorders, taking into account the role of a broad range of potential confounders. A large international cohort (n=1888) with ICD-10 non-affective psychosis was evaluated both at baseline during a hospital admission and three months after discharge. Trained interviewers administered a global functioning scale (GAF) and a psychopathological scale (BPRS) at baseline and follow-up). Baseline BPRS psychopathological dimensions were extracted using Principal Component Analysis. Results of multiple linear regression analyses demonstrated that affective symptoms (depressive or manic) prospectively predict a better global functioning, whilst agitation/cognitive symptoms determined poorer global functioning. Other predictors showing an independent effect on better global functioning were medication compliance, country of residence, female gender, married or coupled status, younger age and having a diagnosis of schizoaffective disorder rather than schizophrenia or other ICD-10 psychosis. A predicting model for global functioning in patients with psychosis is provided, showing that assessment of affective and agitation/cognitive symptoms should be emphasised during admission as they can be more informative than positive/negative symptoms in prospectively planning follow-up care that is geared towards a better functional recovery.

Abstract
BACKGROUND Apathy, a complex neuropsychiatric syndrome, commonly affects patients with Alzheimer's disease. Prevalence estimates for apathy range widely and are based on cross-sectional data and/or clinic samples. This study examines the relationships between apathy and cognitive and functional declines in non-depressed community-based older adults. METHODS Data on 1,136 community-dwelling adults aged 50 years and older from the Baltimore Epidemiologic Catchment Area (ECA) study, with 1 and 13 years of follow-up, were used. Apathy was assessed with a subscale of items from the General Health Questionnaire. Logistic regression, t-tests, chi2 and Generalized Estimating Equations were used to accomplish the study's objectives. RESULTS The prevalence of apathy at Wave 1 was 23.7%. Compared to those without, individuals with apathy were on average older, more likely to be female, and have lower Mini-mental State Examination (MMSE) scores and impairments in basic and instrumental functioning at baseline. Apathy was significantly associated with cognitive decline (OR = 1.65, 95% CI = 1.06, 2.60) and declines in instrumental (OR = 4.42; 95% CI = 2.65, 7.38) and basic (OR = 2.74; 95%CI = 1.35, 5.57) function at 1-year follow-up, even after adjustment for baseline age, level of education, race, and depression at follow-up. At 13 years of follow-up, apathetic individuals were not at greater risk for cognitive decline but were twice as likely to have functional decline. Incidence of apathy at 1-year follow up and 13-year follow-up was 22.6% and 29.4%, respectively. CONCLUSIONS These results underline the public health importance of apathy and the need for further population-based studies in this area.

Abstract
BACKGROUND To promote clinical application of the Schedules for Clinical Assessment in Neuropsychiatry (SCAN) system a shorter version (the mini-SCAN) was devised. Its psychometric properties were unknown. AIMS To establish the validity and practical properties of the mini-SCAN. METHOD One hundred and six participants were interviewed twice, once with the SCAN and once with the mini-SCAN. The level of agreement was established for the categories: no disorder, affective disorders, anxiety disorders, non-affective psychotic disorders, affective psychotic disorders. RESULTS The mini-SCAN is a valid instrument. Most kappa values were around 0.90. Only for the class of affective psychotic disorders was the agreement moderate. Mean duration of the mini-SCAN interviews was 25 min shorter than the SCAN interviews. Participants and interviewers were generally satisfied with the interview format and questions.
