The aim of this study was to perform a broadranging scientometric analysis to evaluate key themes and trends over the past decades, informing future lines of research. We searched the Web of Science Core Collection from inception until December , , using the appropriate search terms such as "physical activity" or "mental health," with no limitation of language or time. Eligible studies were articles, reviews, editorial material, and proceeding papers. We retrieved , documents published between and. The annual scientific production is exponential with a mean annual growth rate of. % since. The co-cited reference network identified distinct clusters that presented significant modularity and silhouette scores indicating highly credible clusters (Q =. , S = .). This network identified major research trends on physical activity, namely cardiovascular diseases, somatic disorders, cognitive decline/dementia, mental illness, athletes' performance, related health issues, and eating disorders, and the COVID-pandemic. A focus on the latest research trends found that greenness/urbanicity (), concussion/chronic traumatic encephalopathy (), and COVID-() were the most active clusters of research. The USA research network was the most central, and the Chinese research network, although important in size, was relatively isolated.

Bereavement is a universal experience, and its association with excess morbidity and mortality is well established. Complicated grief is a process that by its length or intensity is considered pathological but not considered as a distinct mental disorder in the present international classifications: ICD-10 and DSM-IV-TR. For some individuals, if intense grief persists, is distressing and disabling, and may meet criteria as a distinct mental disorder. This definition evolved with the implementation of a proposed criteria for a persistent complex bereavement disorder in the section of "condition of further study"s of the new DSM-5 after the debate raised by the proposition of several authors to include a distinct mental disorder. We tried to illustrate that complex question with a non exhaustive review and with a case report of a clinical situation of a female that was treated in a crisis center in Geneva, following the sudden death of her husband.

It is described as a chronic condition characterized by reactions, aversion to specific sounds that result in subsequent emotional. Indeed, this condition is relatively unknown and few psychiatrists have already faced this disorder causing in some individuals severe impairment. The investigation of a patient suffering of misophonia with severe impairment that we took into care in an outpatient psychiatric clinic in Geneva contributes to a better understanding of this condition and indicates potential factors that may co-occur and influence the clinical presentation. The good response in psychotherapy, has led us to carry out a brief review of the literature in order to better define and identify this disorder.

Many studies have reported that weight gain is only the premise of a series of metabolic disturbances and cardiovascular complications. In this context, we have established since June 2017 in an ambulatory centre in Geneva, a 4F program (Fit, Fun, Feel and Food), to optimize the measures and strategies needed to prevent and reduce weight gain in these patients. This transversal program is naturalistically and systematically centered on physical activity, healthy diet and improved body perception. We will show some preliminary results of 4F program.

Despite a relative symptomatic improvement in the adult form of the disorder persists into adulthood in more than 50% of cases. The transitioning from childhood into adolescence and adulthood, increase social and cognitive demands. We summarize in this presentation the reconceptualisation of neuropsychological abnormalities in multiple cognitive domains, in specific aspects of executive functions (workink memory, ability to inhibit behaviors, slow cognitive processing.. .) in adult with ADHD. Indeed results from neuroimaging studies suggests that the structural and functional brain abnormalities observed in children with ADHD persist into adult ADHD. For a better understanding, we will mention other areas of promising translational researches (genetics, sleep and circadian rhythms, and animal models of ADHD). In conclusion, we will underline how these new approaches will help clinicians and searchers to develop pharmacological and specific psychotherapeutic interventions specifically addressed to improve cognitive deficit in patients with ADHD.

This easyaccess drug seems to have a high addictive potential among specific populations and is now listed by the World Health Organization (WHO) as being as dangerous as benzodiazepines for dependence and abuse. Many side effects have been reported, but drug-induced mania is still extremely rare. We conducted a systematic review to study the zolpidem-induced stimulation, euphoric or manic effects. Methods: MEDLINE, PsycINFO, Science Direct, and Google Scholar were searched for articles in English, French, German, Italian and Spanish published up to the 15 th October 2018. Results: Eighteen relevant cases were identified, highlighting the need for more reports; therefore, one case that occurred in our department was included. The mean usual dose was 363.31 mg (± 292.2), the minimum dose was 10 mg, the maximum dose was 2000 mg, and the mean intake duration was 35.20 months (±48.0). We found that 89.4% of cases were euphoric and 15.7% had drug-induced mania with delusions. A total of 15.7% of cases took zolpidem for relaxant and stimulant effects, 47% of cases suffered various depression or anxiety disorders, of which 62.5% used zolpidem to cope with depression or an anxiety disorder. A total of 26.3% of cases had concomitant drug dependence or abuse. Seventy-five percent of cases suffering from depression consumed zolpidem for more than one year, with significantly more increased daily doses than in non-depressed cases (p<0.5). Conclusions: The latest FDA recommendations for lowering zolpidem doses should be adopted by all countries. Zolpidem prescriptions should be contraindicated for populations with identified risk factors.

We evaluated, retrospectively, clinical response to a 6-month minimum course of M-ECT in 25 patients with a diagnosis of bipolar disorder or schizoaffective disorder according to DSM IV-TR criterion. Our study demonstrated a significant improvement of Global Assessment of functioning (GAF) scores after a six month minimum course of M-ECT (34.8 ± 12.6 vs 65.6 ± 10.8; P&lt;0.05) as well as Brief Psychiatric Rating Scale scores (BPRS): 79.3 ± 12.4 vs 43.4 ± 10.2; P&lt;0.05). We observed a slight increase of Mini Mental State Examination (MMSE) scores after M-ECT; nonetheless, it was not statistically significant (24.2 ± 2.4 vs 26.2 ± 2.4; P=0.2). Regarding the mean duration of hospitalizations, we showed a statistically significant decrease in the median number of days of hospitalization (72 [59-93.50] days before M-ECT vs 43 [25-76] days since the first M-ECT; P=0.017). Maintenance ECT allowed a significant improvement in psychiatric symptoms and global functioning of the patients included in this study, as well as a decrease in the number of days of hospitalization. However, our pattern is limited because of its small size; so, further prospective studies in this field, including larger population is highly recommended.

These disorders are often poorly diagnosed or misdiagnosed because of sharing common clinical features with psychotic disorders, but requiring a very different trajectory of care. Repeated clinical situations in a crisis centre in Geneva provided us with a critical overview of current evidence of knowledge in clinical and etiopathological field about dissociative disorders. Because of their multiple expressions and the overlap with psychotic disorders, we focused on the clinical aspects using three different situations to better understand their specificity and to extend our thinking to the relevance of terms "neurosis" and "psychosis. " Finally, we hope that this work might help physicians and psychiatrists to become more aware of this complex set of disorders while making a diagnosis.

Inpatient services faced the challenge of offering acute psychiatric while implementing strict infection control measures. There is, however, a lack of studies investigating the use of coercive measures during the pandemic and their relation to hospitalizations and symptom severity. Aims To investigate the effects of the CoVID outbreak on psychiatric admissions, use of seclusion and symptom severity. Method Using routine data from 2019 and 2020 gathered in the Department of Psychiatry at the Geneva University Hospitals, we performed an interrupted time series analysis. This included the number of psychiatric hospitalizations, the proportion of people who experienced seclusion and the average severity of symptoms as measured by the Health of Nations Outcome Scale (HoNOS). Dependent variables were regressed on the time variable using regression model with bootstrapped standard...
