Clinical features and outcomes of COVID-19 patients hospitalized for psychiatric disorders: a French multi-centered prospective observational study.

BACKGROUND: Patients with psychiatric disorders are exposed to high risk of COVID-19 and increased mortality. In this study, we set out to assess the clinical features and outcomes of patients with current psychiatric disorders exposed to COVID-19. METHODS: This multi-center prospective study was conducted in 22 psychiatric wards dedicated to COVID-19 inpatients between 28 February and 30 May 2020. The main outcomes were the number of patients transferred to somatic care units, the number of deaths, and the number of patients developing a confusional state. The risk factors of confusional state and transfer to somatic care units were assessed by a multivariate logistic model. The risk of death was analyzed by a univariate analysis. RESULTS: In total, 350 patients were included in the study. Overall, 24 (7%) were transferred to medicine units, 7 (2%) died, and 51 (15%) patients presented a confusional state. Severe respiratory symptoms predicted the transfer to a medicine unit [odds ratio (OR) 17.1; confidence interval (CI) 4.9-59.3]. Older age, an organic mental disorder, a confusional state, and severe respiratory symptoms predicted mortality in univariate analysis. Age >55 (OR 4.9; CI 2.1-11.4), an affective disorder (OR 4.1; CI 1.6-10.9), and severe respiratory symptoms (OR 4.6; CI 2.2-9.7) predicted a higher risk, whereas smoking (OR 0.3; CI 0.1-0.9) predicted a lower risk of a confusional state. CONCLUSION: COVID-19 patients with severe psychiatric disorders have multiple somatic comorbidities and have a risk of developing a confusional state. These data underline the need for extreme caution given the risks of COVID-19 in patients hospitalized for psychiatric disorders.

Magnesium in the treatment of alcohol withdrawal syndrome: a multicenter randomized controlled trial.

OBJECTIVE: Alcohol withdrawal syndrome (AWS) is a frequent and potentially life-threatening condition experienced in alcohol use disorder. Since hypomagnesemia is involved in AWS's severity, we conducted a multicenter double-blind randomized placebo-controlled trial to examine the efficacy of oral magnesium supplementation as an adjuvant therapy of AWS. MATERIAL AND METHODS: Inpatients were recruited in six different centers if they had a baseline score higher than eight on the Revised Clinical Institute Withdrawal Assessment for Alcohol (CIWA-Ar). The experimental treatment was magnesium lactate dehydrate, administrated three times per day providing a total of 426.6 mg per day and up to 15 days. The primary endpoint was the significant between-group difference of the CIWA-Ar total score change from baseline to 3 days later. The treatment group and baseline score were introduced as covariables in an analysis of covariance. RESULTS: A total of 98 inpatients were included {71.4% of men; mean age of 49.1 years [standard deviation (SD): 10.3]}. In the intention-to-treat population, the mean reduction of the CIWA-Ar score in the experimental group between baseline and 3 days later was 10.1 (SD: 5.2), whereas it was 9.2 (SD: 3.9) in the control group. The absolute difference of the adjusted mean in the experimental group compared with the control group was -0.69 (SD: 0.72), which did not correspond to a significant between-group difference (P = 0.34). Per-protocol analysis and sensitivity analyses also supported this result. Supplementary analyses found no significant difference regarding benzodiazepine consumption, magnesium blood concentration, and satisfaction to care. CONCLUSIONS: The present study does not support the rationale of systematic oral magnesium supplementation in patients with AWS.

Associated and intermediate factors between genetic variants of the dopaminergic D2 receptor gene and harmful alcohol use in young adults.

Dopamine receptor D2 (DRD2) and ankyrin repeat and kinase domain-containing protein 1 (ANKK1) genes have received considerable attention for their involvement in alcohol use disorder (AUD), but many questions remain on their exact role. We conducted a population-based case-control and genetic association study in a large sample of young adults. Our aim was to assess the association between DRD2 and ANKK1 single nucleotide polymorphisms (SNPs) and harmful alcohol use, disentangling associated and possible intermediate factors. A total of 1841 college students from the French region Champagne-Ardennes, aged between 18 and 21 years and who reported at least one lifetime alcohol consumption, were included in this study. Allele frequencies were analysed according to harmful alcohol use (assessed through the Alcohol Use Disorder Identification Test [AUDIT] questionnaire). Different substance use disorders, including nicotine and cannabis dependences, were also assessed through questionnaires, as was a list of potential associated factors (e.g., major depressive episode, conduct disorder, attention-deficit/hyperactivity disorder [ADHD], school failure, sugar consumption, sexual trauma, parents' use of alcohol, tobacco or cannabis). We found that DRD2 rs1800498 was associated with harmful alcohol use. Many factors were detected, but a global path analysis revealed that DRD2 rs1800498 had a significant direct effect on harmful alcohol use and that early age at first alcohol consumption and depressive symptoms moderated this effect. This study suggests an interplay between harmful alcohol use, DRD2 genotypes and other risk factors that, with a full understanding, could be useful for preventive purposes.

Time Devoted to Individual, Collective, and Two-Person Sports: Its Association with Risk of Exercise Addiction and Alcohol Use Disorder.

INTRODUCTION: Although sport activities have beneficial effects on health, excessive practice can lead to exercise addiction (EA), which can be associated with other addictive behaviors. However, results regarding the comorbidities between EA and alcohol use disorder (AUD) remain heterogeneous. This study aims to investigate the relationship between a proxy of AUD and different sport practices, more specifically focusing on EA. METHODS: One thousand nine hundred eighty-five (N = 1,985) participants were recruited online and selected to represent the French adult population. Participants were asked to answer questions regarding sport activity, with the EA inventory questionnaire investigating EA, and alcohol consumption, with the CAGE questionnaire investigating a proxy of AUD (score ≥2). RESULTS: AUD was associated with a higher risk of EA and with more time devoted to collective sports (such as football) and two-person sports (such as tennis). The risk of EA was higher for individual sports (such as running), and the risk of AUD seems to increase with the level of physical activity for collective sport but to decrease for individual sports. The type of sports partly but significantly mediated the relationship between AUD and EA. CONCLUSIONS: Results support the hypothesis that different types of sport have different risks for EA (individual sports being more concerned) and AUD (collective sports being more concerned). Results suggest that the type of sports may be a crucial variable to understand how physical activity can be a risk factor for alcohol disorders. The social dimension of collective sports should be further investigated to facilitate preventive approaches.

[Suicide, a separate entity in psychiatry]. / Le suicide, une entité à part en psychiatrie.

Since ancient times, the subject of suicide has been recurrently discussed in societies. Whether it is a selfish or altruistic act, the ethical debate has always been intense. Today, the suicidal act is at the center of the public debate with the subject of euthanasia and assisted suicide. Philosophers, theologians, sociologists, doctors and jurists share their thoughts on this subject, which is still considered "taboo". Between suicide, suicidal ideas or suicidal crisis, the stakeholders are involved in the field of prevention and are mobilizing to propose innovative treatments.
