Prevalence of major depressive disorder and post-traumatic stress disorder among first-time sleep center attendees.

BACKGROUND: Sleep disorders and psychiatric disorders stand in a bidirectional relationship. Sleep complaints are prominent in populations with psychiatric disorders, especially amongst people with major depressive disorder (MDD) and post-traumatic stress disorder (PTSD). Consultations at sleep clinics offer opportunities to screen psychiatric disorders and to propose primary psychiatric care. METHODS: This descriptive study was conducted on 755 patients making their first visit to sleep clinic, with 574 seeking consultation for suspected obstructive sleep apnoea-hypopnoea syndrome (OSAHS), 139 for complaints of insomnia, and 42 for complaints of hypersomnia. The results of 387 screening scales for MDD (BDI-II) and 403 for TSPT (PCL-5) were compared according to the reason given for the consultation. RESULTS: In the whole group, 12.1 % of patients presented a positive MDD screening and 4.9 % for PTSD. Among patients presenting with insomnia, 19.8 % had a positive screening for MDD, as compared to 9.3 % in patients presenting with suspected OSAHS (p = 0.02). Regarding PTSD, 9.7 % of patients seeking consultation because of insomnia had a positive screening, compared to 2.9 % among patients with suspected OSAHS (p = 0.03). Among patients with a positive screening for MDD, 40.5 % were not receiving antidepressant or mood stabilizer treatment. CONCLUSION: Positive screening for MDD and PTSD are frequent in patients who attend sleep centers, especially amongst those presenting with insomnia. Nearly half of the patients with positive screening for MDD or PTSD were not receiving a dedicated pharmacological treatment. These figures emphasize systematic screening for psychiatric disorders in sleep clinics.

Definitions and Measurement Tools for Assessing Parental Reactions to LGB People Coming Out: A Critical Review.

Parental responses to young people's coming out as lesbian, gay or bisexual (LGB) are a crucial experience in identity formation and subsequent mental health outcomes. However, how parents react to coming out varies and remains relatively imprecise in the literature. The aim of the present critical review was to explore and discuss the different definitions and measurement tools used in studies assessing perceived parental reactions to the coming out of LGB people aged 18 years and over. Following PRISMA guidelines, a review of 14 selected articles was carried out to examine the different tools used. Then, based on this selection of articles, a review of the different proposed definitions of parental reactions was carried out. Analysis revealed that the Perceived Parental Reactions Scale emerged as the most widely used and most appropriate international scale for capturing the diversity of perceived parental reactions. Then, parental responses were often addressed in a dichotomous manner, focusing primarily on acceptance or rejection. Future studies will need to consider a more nuanced approach to understanding parental reactions to coming out.

Esketamine-induced post-traumatic stress disorder flashbacks during treatment-resistant depression indication: is it just a side effect?

Background: Posttraumatic stress disorder (PTSD) is a severe and frequent affection that is highly comorbid to major depressive disorder. Comorbid PTSD and depression are usually treatment-resistant, with a high risk of functional impairment and suicide. Esketamine nasal spray is a recent validated treatment for treatment-resistant depression (TRD), but its efficacy on comorbid TRD-PTSD remains insufficiently documented. In particular, flashbacks can occur during esketamine administration and their influence on clinical outcomes is unknown. Objectives: Our main objective was to describe esketamine-induced traumatic flashbacks and their impact on clinical trajectories within a sample of patients with comorbid TRD-PTSD. Methods: We retrospectively collected clinical data of patients receiving esketamine nasal spray for TRD with comorbid PTSD who experienced at least one flashback of their trauma during esketamine sessions across 11 psychiatric departments. Results: Between February 2020 and March 2023, 22 adult patients with TRD met inclusion criteria. In sixteen patients (72.7%) flashbacks disappeared as the sessions progressed. In six patients (27.3%), esketamine treatment was stopped because of persistent flashbacks. When esketamine was continued, clinical response was observed both for depression and PTSD (depression response rate: 45.5% and remission rate: 22.7%; PTSD response rate: 45.5% and remission: 18.2%). Limitations: The retrospective design of the study and the absence of a comparator group are the main limitations of our study. Conclusions: Our results suggest that the occurrence of esketamine-induced traumatic flashbacks does not hinder clinical response. On the contrary, when managed appropriately and combined with targeted psychotherapy, it could even contribute to positive outcomes.

Cerebral Metabolic Signature of Chronic Benzodiazepine Use in Nondemented Older Adults: An FDG-PET Study in the MEMENTO Cohort.

OBJECTIVE: We sought to examine the association between chronic Benzodiazepine (BZD) use and brain metabolism obtained from 2-deoxy-2-fluoro-D-glucose (FDG) positron emission tomography (PET) in the MEMENTO clinical cohort of nondemented older adults with an isolated memory complaint or mild cognitive impairment at baseline. METHODS: Our analysis focused on 3 levels: (1) the global mean brain standardized uptake value (SUVR), (2) the Alzheimer's disease (AD)-specific regions of interest (ROIs), and (3) the ratio of total SUVR on the brain and different anatomical ROIs. Cerebral metabolism was obtained from 2-deoxy-2-fluoro-D-glucose-FDG-PET and compared between chronic BZD users and nonusers using multiple linear regressions adjusted for age, sex, education, APOE ε 4 copy number, cognitive and neuropsychiatric assessments, history of major depressive episodes and antidepressant use. RESULTS: We found that the SUVR was significantly higher in chronic BZD users (n = 192) than in nonusers (n = 1,122) in the whole brain (beta = 0.03; p = 0.038) and in the right amygdala (beta = 0.32; p = 0.012). Trends were observed for the half-lives of BZDs (short- and long-acting BZDs) (p = 0.051) and Z-drug hypnotic treatments (p = 0.060) on the SUVR of the right amygdala. We found no significant association in the other ROIs. CONCLUSION: Our study is the first to find a greater global metabolism in chronic BZD users and a specific greater metabolism in the right amygdala. Because the acute administration of BZDs tends to reduce brain metabolism, these findings may correspond to a compensatory mechanism while the brain adapts with global metabolism upregulation, with a specific focus on the right amygdala.

Bullying and self-harming behavior in universities - A cross-sectional study of a sample of 327 university students.

INTRODUCTION: Bullying is a widespread public health issue, found in different contexts (e.g. schools, universities, workplaces, families), and it has negative consequences on both the perpetrator and the victim. There is a lack of studies addressing bullying among university students in Arab countries and more specifically in Lebanon. The objective of our study was to determine the prevalence of bullying among a sample of university students in Lebanon, its forms, and associated factors. METHODS: The study consists of a cross-sectional online survey addressed to university students in Lebanon that evaluates sociodemographic data, presence and type of bullying, history of bullying during childhood, adverse childhood experiences, daily life functioning, and mental health status (reported psychiatric disorders, substance use, self-harming behaviors, and suicidal attempts). Chi-Square and Fisher's exact tests were used to compare the results between victims of bullying and the rest of the sample. RESULTS: Three hundred and twenty-seven university students participated in this study. The prevalence of bullying was 14.1%. The main forms of reported bullying were verbal (58.7%) and social bullying (65.2%). The main associated factors were being a witness of bullying at university (84.8% vs. 56.2% - P<.001) and history of cyberbullying (13% vs. 4.6% - P=.024). Among students who reported current bullying, 28.3% had a psychiatric diagnosis, 19.6% reported substance use, 15.2% had self-harming behaviors, and 8.7% had suicide attempts. Victims of bullying in the university reported a significant negative impact on their daily lives (lack of interest in daily activities, academic decline) (83.7%) and mental health concerns (psychiatric disorders, substance use, suicide attempts) (88.4%). CONCLUSION: Even though bullying is an event less experienced in university than in school, it is nevertheless still present with potential negative impact on the victims. Bullying in a university setting is a public health issue that could benefit from more studies as well as prevention and intervention programs.

Protective factors of suicidal behaviors in children and adolescents/young adults: A literature review.

BACKGROUND: Suicidal behaviors present a public health challenge in children and adolescents. Although the risk factors have long been well documented, protective factors have only been documented for a few years, and there has not been a literature review concerning the suicidal behaviors of children and adolescents since 2006. METHODS: Relevant articles were collected using the Medline/PubMed, Web of Science, and ScienceDirect databases. Studies meeting the following inclusion criteria were included: age of participants from 6 to 19 years, qualitative and quantitative cohort or case-control studies, multivariate analysis studies, and studies with significant results for at least one protective factor. The methodology used in this review is based on the PRISMA criteria. RESULTS: A total of 26 studies were included in this review, which highlights various individual and environmental protective factors. The results were too heterogeneous to perform a meta-analysis, and therefore the discussion is in the form of a narrative summary. High-quality relationships with family and in the school environment were the most frequently found protective factors. The presence of positive links with peers, with other adults, and with the culture of origin was also noted. On an individual level, self-esteem, emotional intelligence, and particular coping abilities were found to be the most important protective factors. CONCLUSION: There are numerous important protective factors for suicidal behaviors in children and adolescents and also for adapting care to their needs. A future challenge will be to determine the best protective factors to be consolidated or strengthened using self-assessment tools that are already in use or being developed.

EMDR for symptoms of depression, stress and burnout in health care workers exposed to COVID-19 (HARD): A study protocol for a trial within a cohort study.

Background: Stressful events during a pandemic are a major cause of serious health problems, such as burnout, depression and posttraumatic stress disorder (PTSD) among health care workers (HCWs). During three years, HCWs, on the frontline to fight the COVID-19 pandemic, have been at an increased risk of high levels of stress, anxiety, depression, burnout and PTSD. Regarding potential psychological interventions, Eye Movement Desensitization & Reprocessing (EMDR) is a structured, strongly recommended therapy based on its well-known efficacy in reducing PTSD symptoms and anxiety.Objectives: This study, designed as a trial within a cohort (TwiC), aims to 1) estimate the prevalence of depression, burnout and PTSD in a sample of HCWs after experiencing the COVID-19 emergency (cohort part) and 2) assess the efficacy and acceptability of 'EMDR + usual care' for HCWs from the cohort who report significant psychological symptoms (trial part).Methods: The study, designed as a TwiC, consists of a prospective cohort study (n = 3000) with an embedded, pragmatic, randomized open-label superiority trial with two groups (n = 900). Participants included in the trial part are HCWs recruited for the cohort with significant symptoms on at least one psychological dimension (depression, burnout, PTSD) at baseline, 3 months or 6 months, determined by using the Patient Health Questionnaire (PHQ-9), Professional Quality of Life (ProQOL) scale, and PTSD Checklist for the DSM-5 (PCL-5). The intervention consists of 12 separate EMDR sessions with a certified therapist. The control group receives usual care. The trial has three primary outcomes: changes in depression, burnout and PTSD scores from randomization to 6 months. All participants are followed up for 12 months.Conclusions: This study provides empirical evidence about the impact of the COVID-19 pandemic and the mental health burden it places on HCWs and assesses the effectiveness of EMDR as a psychological intervention.Trial registration NCT04570202.

Health care workers are at increased risk of stress, anxiety, depression, burnout and PTSD following the COVID-19 pandemic.In this study, the effectiveness of EMDR in reducing depression, burnout and PTSD in health care workers exposed to COVID-19 is investigated.In this study, an original 'trial within a cohort' (TwiC) design that consists of a cohort study with an embedded pragmatic randomized trial is used.The study is fully web-based, including online screening, consent and assessments.

[How potentially inapropriate are psychotropic drugs prescribing in acute psychiatric unit for the elderly? Results from a large multicentric audit in France]. / Prescription inadaptée de psychotropes en unités de psychiatrie aiguë pour personnes âgées : une étude transversale multicentrique.

Adverse drug reactions (ADRs) are a major public health issue, especially when it comes to the elderly. Potentially inappropriate prescribing (PIP) are one of the causes of ADRs in older people. A PIP can be defined as a prescription for which the benefit/risk ratio is unfavourable compared to other therapeutic alternatives. Psychotropic drugs are the second highest risk class for ADRs in the elderly. In order to reduce the prevalence of PIP, prescription assistance tools have been created. An inventory of PIP of psychotropic drugs in older patients hospitalized in psychiatry units was carried out in a French regional setting in 2019. A criteria grid was established based on 2 tools: STOPP/START criteria and Laroche's list adapted to French practice. This grid targeted each class of psychotropic drugs, drugs with a high anticholinergic burden and non-recommended combinations of psychotropic drugs. Three hundred forty-seven patients were included. A high prevalence of PPI was found for each class of psychotropic drugs. The highest prevalence of PPI was found among benzodiazepines (90.3%): long-term prescription, long half-life drugs, respiratory insufficiency or cognitive impairment condition. 56.5% of the subjects had a not-recommended combination of psychotropic drugs (prescription of drugs of the same pharmacotherapeutic class), 26% had a PIP of antipsychotics: prescription for insomnia, use of phenothiazine, 11.8% of drugs with anticholinergic properties and 7.4% of antidepressants: especially prescription of tricyclic drugs. These results obtained on a large population underline the interest of considering the specificities of prescriptions in the elderly. It shows both the interest and the limits of the current criteria defining the PIP in the context of a hospitalization in psychiatry for an acute disorder in elderly subjects.

Benzodiazepine use and neuroimaging markers of Alzheimer's disease in nondemented older individuals: an MRI and 18F Florbetapir PET study in the MEMENTO cohort.

Recent evidence suggests an association between benzodiazepines (BZDs) use and lower brain amyloid load, a hallmark of AD pathophysiology. Other AD-related markers include hippocampal atrophy, but the effect of BZDs on hippocampal volume remains unclear. We aimed at 1) replicating findings on BZDs use and brain amyloid load and 2) investigating associations between BZDs use and hippocampal volume, in the MEMENTO clinical cohort of nondemented older adults with isolated memory complaint or light cognitive impairment at baseline. Total Standardized Uptake Value Ratio (SUVR) of brain amyloid load and hippocampal volume (HV) were obtained, respectively, from 18F Florbetapir positron emission tomography (PET) and magnetic resonance imaging (MRI), and compared between BZD chronic users and nonusers using multiple linear regressions adjusted for age, sex, educational level, ApoE ε4 genotype, cognitive and neuropsychiatric assessments, history of major depressive episodes and antidepressant intake. BZD users were more likely to manifest symptoms of depression, anxiety and apathy. In the MRI subgroup, BZD users were also more frequently females with low education and greater clinical impairments as assessed with the clinical dementia rating scale. Short- versus long-acting BZDs, Z-drugs versus non-Z-drugs BZDs, as well as dose and duration of BZD use, were also considered in the analyses. Total SUVR and HV were significantly lower and larger, respectively, in BZD users (n = 38 in the PET subgroup and n = 331 in the MRI subgroup) than in nonusers (n = 251 in the PET subgroup and n = 1840 in the MRI subgroup), with a medium (Cohen's d = -0.43) and low (Cohen's d = 0.10) effect size, respectively. Short-acting BZDs and Z-drugs were more significantly associated with larger HV. We found no effect of dose and duration of BZD use. Our results support the involvement of the GABAergic system as a potential target for blocking AD-related pathophysiology, possibly via reduction in neuronal activity and neuroinflammation. Future longitudinal studies may confirm the causal effect of BZDs to block amyloid accumulation and hippocampal atrophy.

Forum theater staging of difficult encounters with patients to increase empathy in students: evaluation of efficacy at The University of Angers Medical School.

BACKGROUND: Physician empathy has been associated with improved clinical outcomes and lower physician burnout. We evaluated whether forum theater (FT), a form of applied drama that allows participants to enter the performance and represent the actions associated with emotions, would foster empathy in medical students, and which underlying variables would be associated to empathy scores. METHODS: Three classes totaling 488 fourth-year medical students participated in the study. Forum theater was used to explore difficult encounters with patients and family members: announcement of cancer, fall at home of an elderly person requiring hospitalization, appointment with a patient suffering from depression, announcement of diabetes in an adolescent. The first scene was played by actors in front of a group of students, then audience members were asked to enter the performance and, by taking over the role of the "physician-actor," to explore alternative interactions. All the students followed two sessions as actors and observers in random order and were randomly assigned to FT sessions after 36 or 56 weeks of clinical rotations. They completed the Jefferson Scale of Physician Empathy (JFSE) anonymously. RESULTS: Students were 22.1 ± 1.5 years old (43% males). Empathy scores increased after each session: 102.0 ± 9.8 before the sessions, 106.3 ± 9.8 after session 1 and 107.8 ± 11.5 after session 2 (p <  0.05). In regression models, gender (F vs. M, + 3.0 ± 1.0, p <  0.001) and position in the session (actor vs. observer, + 2.1 ± 1.0, p < 0.05) were significant determinants of JFSE scores, whereas age, session theme, and duration of clinical rotation were not. CONCLUSION: Being an actor in forum theater was a valuable tool for enhancing empathy scores in medical students.

Quetiapine Poisoning and Factors Influencing Severity.

PURPOSE/BACKGROUND: Quetiapine is a relatively new atypical antipsychotic with fewer adverse effects. It is increasingly prescribed to patients. The purpose of this study was to describe the cases of poisoning observed at the western France Poison Control Centre and identify potential risk factors that increase the severity of the cases. METHODS: This was a retrospective study of self-poisoning with quetiapine as reported by the western France Poison Control Centre between 2007 and 2017. RESULTS: There were 372 cases of quetiapine poisoning. Circumstances are known in 367 of 372 cases. There were 75 cases of null severity (grade 0), 133 cases of mild severity (grade 1), 85 cases of moderate severity (grade 2), and 79 cases of high severity (grade 3). Five deaths were listed in this series. The most commonly observed symptoms were neurological and cardiovascular in nature (drowsiness, coma, tachycardia, hypotension). Of these cases, 79.8% included voluntary ingestions. Among 302 cases with coagents, the most common coagents were benzodiazepines (56%), other psychotropic drugs (41%), and antidepressants (37%). An evaluated ingested dose 1500 mg or greater and 2 or more coagents increase the risk of severe poisoning. In particular, concomitant ingestion of benzodiazepines and antidepressants with quetiapine was associated with high severity (odds ratio, 2.478 [confidence interval, 1.3-4.723]; odds ratio, 1.820 [confidence interval, 1.010-3.316]). CONCLUSIONS: Quetiapine may lead to severe poisoning for which there is currently no specific treatment. Patients and practitioners should be aware of this when quetiapine is prescribed, particularly when used in combination with other medications, and in order to deal with cases of poisoning.

Decision-Making Measured by the Iowa Gambling Task in Patients with Alcohol Use Disorders Choosing Harm Reduction versus Relapse Prevention Program.

AIMS: Two main therapeutic programs were offered to patients suffering from alcohol use disorders (AUDs): avoid the alcohol by abstinence or controlling their consumption. After information and motivational sessions, the patient chooses his own therapeutic plan. However, patients with AUD exhibit poor decision-making. The purpose of this study was to investigate the decision-making in AUD by comparing patients who chose to reduce and control their consumption to those who chose abstinence program. METHODS: Sixty-seven subjects with alcohol use disorder were included (AUD group) for treatment, choosing either a relapse prevention program (RPP) or a harm reduction program (HRP). Patients were compared to a healthy control group (n = 31). Cognitive skills were assessed through the Montreal Cognitive Assessment test, the National Adult Reading Test, the Trail Making Test and the Iowa Gambling Task (IGT). RESULTS: Thirty-seven patients with AUD chose the RPP while 30 followed a HRP. The AUD group performed worse than controls on the IGT. The RPP group had significantly lower performance than both HRP and control groups (these later groups being not statistically different). No correlation was observed between the available clinical, cognitive and intellectual measures. CONCLUSION: This study confirms that the decision-making process of patients with an alcohol use disorder is impaired. However, the 2 groups differ on the IGT scores, despite comparable clinical and cognitive profiles. The patients' decision-making abilities could be a useful guide when developing therapeutic programs.

How Much Do Benzodiazepines Matter for Electroconvulsive Therapy in Patients With Major Depression?

BACKGROUND: Electroconvulsive therapy (ECT) is one of the most effective treatments for major depressive disorder (MDD), especially in cases of treatment-resistant MDD. Because of their pharmacological profiles, benzodiazepines (BZDs) are suspected to decrease the efficacy of ECT. This study investigated the effect of BZDs on ECT-induced clinical outcomes and ECT course parameters in patients with MDD. METHOD: The impact of BZDs on severity of depression (Montgomery-Asberg Depression Rating Scale scores) and on ECT course parameters (seizure threshold, clinical and electroencephalographic seizure duration) was investigated in 70 patients with MDD who received an ECT course using dose-titration method (22 received concomitant BZDs). RESULTS: Lower remission rates (52.0%) and smaller decreases in Montgomery-Asberg Depression Rating Scale scores were observed in the non-BZD group than in the BZD group (81.2%, P = 0.02). There were no significant differences between the 2 groups regarding seizure duration and seizure threshold. LIMITATIONS: This was a retrospective study. Impact of BZDs on anxiety and cognition was not assessed. CONCLUSIONS: Benzodiazepines increased the clinical efficacy of ECT when delivered using dose-titration method and bitemporal stimulation. Further studied are needed to understand the interaction between BZDs and ECT on clinical outcomes.

Continuous positive airway pressure therapy for obstructive sleep apnoea and psychotropic drug use: a retrospective observational matched-cohort study.

Patients with obstructive sleep apnoea (OSA) frequently present symptoms of depression, anxiety and insomnia and continuous positive airway pressure (CPAP) can improve these symptoms. Using a real-world administrative database, we analysed the trend of psychotropic drug use (antidepressants, anxiolytics and hypnotics) on a long-term period in OSA individuals before-after CPAP initiation. A total of 869 OSA individuals to whom psychotropic drugs were prescribed were followed for 4 years. They were matched to 2,607 non-OSA individuals, who were similar in terms of demographics, chronic diseases and care consumption. Generalized estimating equations models were used to compare psychotropic drug defined daily doses (DDD). Results showed no significant differences in mean trends of psychotropic drug DDD between OSA individuals and non-OSA matched controls during the three years following CPAP initiation. Only time had a significant effect on DDD, which decreased in both groups: -9% in Y1 and -17% in Y3, compared to Y0 (p-values < 0.0001). Hence, CPAP therapy does not result in an earlier decrease of psychotropic drug use in OSA individuals compared to non-OSA matched controls. Further studies are needed to analyse long-term psychotropic drug use, particularly in non-adherent OSA individuals.

Sex-specific effects of COMT Val158Met polymorphism on corpus callosum structure: A whole-brain diffusion-weighted imaging study.

BACKGROUND: Genetic polymorphisms play a significant role in determining brain morphology, including white matter structure and may thus influence the development of brain functions. The main objective of this study was to examine the effect of Val158Met (rs4680) polymorphism of Catechol-O-Methyltransferase (COMT) gene on white matter connectivity in healthy adults. METHODS: We used a whole-brain diffusion-weighted imaging method with Tract-Based Spatial Statistics (TBSS) analysis to examine white matter structural integrity in intrinsic brain networks on a sample of healthy subjects (N = 82). RESULTS: Results revealed a sex-specific effect of COMT on corpus callosum (CC): in males only, Val homozygotes had significantly higher fractional anisotropy (FA) compared to Met-carriers. Volume-of-interest analysis showed a genotype by sex interaction on FA in genu and rostral midbody of CC, whereby Val males demonstrated higher FA than Met females. CONCLUSIONS: These results demonstrate the key effect of genes by sex interaction, rather than their individual contribution, on the corpus callosum anatomy.

Dissociation between decision-making under risk and decision-making under ambiguity in premanifest and manifest Huntington's disease.

We investigated decision-making under ambiguity (DM-UA) and decision making under risk (DM-UR) in individuals with premanifest and manifest Huntington's disease (HD). Twenty individuals with premanifest HD and 23 individuals with manifest HD, on one hand, and 39 healthy individuals divided into two control groups, on the other, undertook a modified version of the Iowa Gambling Task (IGT), an adaptation of a DM-UA task, and a modified version of the Game of Dice Task (GDT), an adaptation of a DM-UR task. Participants also filled in a questionnaire of impulsivity and responded to cognitive tests specifically designed to assess executive functions. Compared to controls, individuals with premanifest HD were unimpaired in performing executive tests as well as in decision-making tasks, except for the Stroop task. In contrast, individuals with manifest HD were impaired in both the IGT and executive tasks, but not in the GDT. No sign of impulsivity was observed in individuals with premanifest or manifest HD. Our results suggest that the progression of HD impairs DM-UA without affecting DM-UR, and indicate that decision-making abilities are preserved during the premanifest stage of HD.
