The concept of multimorbidity in psychiatry refers to the coexistence of multiple health conditions without conceptualizing a central disorder referring to a patient-centered approach that views every diagnosis equally. It emphasizes a shift from focusing on an index disorder to considering interrelated symptoms crucial in psychiatry due to frequent multimorbidity patterns. In clinical practice, multimorbidity guides patient-centered care helping to address the holistic needs of patients and challenging the organization of mental health care. In research, multimorbidity reshapes study outcomes and promotes the development of patient-reported outcome questionnaires, also posing ethical challenges and advocating for the inclusion of multimorbid patients in personalized interventions. Finally, multimorbidity in psychiatry has public health implications aligning with the socioecological systems perspective. This notion aims to improve prognosis, care, and health costs while impacting global mortality and challenging the conceptualization and organization of psychiatric care.

Dementia is a highly prevalent syndrome with various causes, characterized by cognitive deficit in one or more domains, with important impairment of functioning, which frequently presents with neuropsychiatric symptoms that may include obsessive-compulsive symptoms.

Objectives: The main goal of this meta-analysis was to describe and determine the prevalence of obsessive-compulsive symptoms in dementia.

Materials and methods: To accomplish that, MEDLINE, CENTRAL and Psycnet databases were searched from inception to March 2023. The Joanna Briggs Institute Critical Appraisal Checklist for Studies Reporting Prevalence Data was applied. The principal summary measures were the mean of prevalence of obsessive-compulsive symptoms in patients with dementia and the number of each type of obsession or compulsion.

Results: Of the 643 articles screened, 92 were accepted for full-text assessment. Of these, 30 with information on prevalence of obsessive-compulsive symptoms in dementia or any description of those were included, yielding a total of 37 cohorts (5 studies with two cohorts and 1 study with three cohorts). According to our results, obsessive-compulsive symptoms have considerable prevalence in dementia (35.3%, 23.1-47.6%), namely in frontotemporal dementia (48.4%, 29.8-67.0%); obsessive-compulsive symptoms were less frequent in other dementia diagnosis (17.6%, 9.1-26.2%). The more frequent obsessive contents are symmetry (28.6%) and somatic (20.0%); and the more frequent compulsions are checking (27.4%); hoarding is also a relevant symptom (27.8%).

Discussion: There was considerable heterogeneity in the prevalence of obsessive-compulsive symptoms in frontotemporal dementia, that is, in part related with diagnostic criteria for dementia, as well as obsessive-compulsive symptom assessment. A careful distinction between compulsions and compulsive-like symptoms is fundamental. Hypervigilance for somatic symptoms and concerns about disease and mortality, as well as deficits in cognitive domains like attention and memory may explain why somatic obsessions and checking compulsions are more prevalent.

Conclusions: The present results indicate that obsessive-compulsive symptoms may be prevalent in the clinical course of many patients with dementia, especially frontotemporal dementia. Better instruments are needed to describe obsessive-compulsive phenomena in a reliable and comparable way, particularly in a population such as dementia patients, whose subjectivity is difficult to access.

Introduction: During operational missions, while the management of physical injuries in the field remains the priority, the identification of operational incapacity of psychological origin is necessary as it is equally crucial for the safety of the individual, the group and the mission. The French Military Health Service has developed a Psychological First Aid Training in Operation (PFATO) course based on relational simulations, for military service members. The aim is to identify the early signs of psychological distress in a comrade and to adopt an adapted and protective attitude. PFATO training is also offered to healthcare providers.

Methods: We conducted a descriptive cross-sectional study using a self-administered online questionnaire which was sent after deployment to all physicians or nurses trained in PFATO between July 2019 and July 2021 (n=80). The main objective of our work was to evaluate the relevance of this awareness training among physicians and nurses and to identify specific complementary expectations in operational psychiatry for this population.

Results: We obtained a response rate of 55%. Significantly, 21.62% of participants used PFATO during their last deployment and another 20% observed a team member using PFATO. The circumstances of use as reported by participants included acute stress related to combat, conflict with hierarchy or comrades, and suicidal crisis. Among those who used PFATO, the training helped 87.5% of them to identify signs of psychological distress and 100% of them to assist combatants . All respondents stressed the added value of practical simulations during PFATO education. Moreover, this study also makes it possible to identify adaptations needed to optimize this module for healthcare providers.

Conclusion: The results suggest the value for healthcare provider of training in first-response psychological care using relational simulation based on the model of raising awareness about PFATO.

Objectives: The prevalence of hepatitis C virus (HCV) has been estimated to be approximately ten times higher in patients with psychiatric disorders, but European data are rare and only two French studies have recently been published on the subject. Our objective was to determine the HCV screening rate and the prevalence of HCV in adult patients hospitalised in the largest French psychiatric hospital.

Methods: We conducted a retrospective study of all adult patients hospitalised at GHU Paris, from 2019 to 2022, including age, gender, HCV screening, HCV serological status, and the existence of an ICD-10 diagnosis of psychoactive substance use disorder. Descriptive statistics used means±standard deviations and percentages. Bivariable comparisons used Student's t test and Chi-square test.

Results: The overall HCV screening rate was 55.4% and increased over the four years from 37.1% in 2019 to 69.4% in 2022. Patients screened were significantly younger people and with a substance use disorder than unscreened patients. The prevalence of HCV over this 4-year period was 2.8% and remained stable. The HCV-positive patients were significantly more male, older and more likely to have substance use disorders than the HCV-negative patients.

Conclusions: We found a prevalence rate of HCV ten times higher than the prevalence in the general population, in line with findings in many other European countries. The eradication of HCV will not be possible without the elimination of this "forgotten reservoir" of the virus. Efforts must be made in psychiatric hospitals to test all patients in order to treat patients suffering from hepatitis C with direct-acting antivirals.

Ever since 2018 France has been the only country to approve the gamma aminobutyric acid type B (GABA-B) receptor agonist baclofen for alcohol dependence. This authorization follows a ten-year period of intensive off-label use during which baclofen was used in doses of up to 300 and even 400mg per day to support the gradual reduction of alcohol consumption in patients suffering from alcohol dependence. However, in international clinical trials, baclofen has mainly been studied to support the maintenance of abstinence. The French use of baclofen was therefore somewhat atypical as it paved the way for drug-supported approaches to reducing alcohol consumption, even before nalmefene was marketed. In line with this specific use of baclofen, approval was granted only for alcohol reduction support. However, a recent Cochrane systematic review and meta-analysis by Agabio et al. found significant efficacy only for abstinence maintenance, while no significant effect was found on alcohol reduction outcomes and no dose-response relationship was identified in the analyses. The safety of baclofen was judged to be good. Based on these substantial new results, the Société française d'alcoologie (SFA) now considers that baclofen should also be approved for the maintenance of abstinence. The extension of approval should not lead to the removal of the initial indication or the possibility of using high doses, as some patients have found this therapeutic regimen particularly useful for them. France, which has been a open skies national laboratory on the use of baclofen in alcohol dependence for over ten years, should let this original therapeutic option available to patients. However, it should update the regulatory framework defining the main conditions of access to treatment for patients based on the latest and highest scientific evidence.
