RESUMEN

BACKGROUND: There is growing evidence in the literature that brief contact interventions (BCIs) might be reliable suicide prevention strategies. OBJECTIVE: To assess the effectiveness of a decision-making algorithm for suicide prevention (ALGOS) combining existing BCIs in reducing suicide reattempts in patients discharged after a suicide attempt. METHODS: A randomized, multicenter, controlled, parallel trial was conducted in 23 hospitals. The study was conducted from January 26, 2010, to February 28, 2013. People who had made a suicide attempt were randomly assigned to either the intervention group (ALGOS) or the control group. The primary outcome was the rate of participants who reattempted suicide (fatal or not) within the 6-month study period. RESULTS: 1,040 patients were recruited. After 6 months, 58 participants in the intervention group (12.8%) reattempted suicide compared with 77 (17.2%) in the control group. The difference between groups (4.4%; 95% CI, -0.7% to 9.0%) was not significant (complete-case analysis, P = .059). CONCLUSIONS: These results may help researchers better integrate BCIs into routine health care and provide new insights concerning personalized suicide prevention strategies. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT01123174.

RESUMEN

Despite major recent advances in C-H activation, discrimination between two similar, unactivated C-H positions is beyond the scope of current chemocatalytic methods. Here we demonstrate that integration of regioselective halogenase enzymes with Pd-catalysed cross-coupling chemistry, in one-pot reactions, successfully addresses this problem for the indole heterocycle. The resultant 'chemobio-transformation' delivers a range of functionally diverse arylated products that are impossible to access using separate enzymatic or chemocatalytic C-H activation, under mild, aqueous conditions. This use of different biocatalysts to select different C-H positions contrasts with the prevailing substrate-control approach to the area, and presents opportunities for new pathways in C-H activation chemistry. The issues of enzyme and transition metal compatibility are overcome through membrane compartmentalization, with the optimized process requiring no intermediate work-up or purification steps.

RESUMEN

The aim of this study was to describe the characteristics of children and adolescents admitted to the psychiatric emergency department (ED) of a French public teaching hospital over a six-year study period (2001-2006). Data for all episodes of care in the psychiatric ED from January 1, 2001, to December 31, 2006, delivered to adolescents aged less than 18 years were retrospectively analyzed. During the six-year study period, 335 episodes of care in the psychiatric ED were experienced by 264 different adolescents. They accounted for 2.0% of the 16,754 care episodes of the ED; 164 patients (62.1) were female and the average age was 16.5 (SD = 1.6). The neurotic, stress-related, and somatoform disorders were the most frequent (25.4%) and concerned mainly anxiety disorders (15.2%). The frequency of the absence of psychiatric diagnosis (22.7%) was high. A total of 48 children and adolescents (18.2%) benefited from more than one episode of care. Several factors were associated to a higher number of visits to the ED: substance use, schizophrenia, disorders of adult personality and behaviour, disorders occurring in childhood and adolescence, and dual diagnosis. In conclusion, mental health disorders in children and adolescents are a serious problem associated with several potentially modifiable factors.

RESUMEN

OBJECTIVE: This study examined characteristics of frequent visitors to a psychiatric emergency service in a French public teaching hospital over six years. Diagnostic variability of psychotic disorders was documented. METHODS: A retrospective review of the service's administrative and medical databases identified 1,285 patients with more than one visit during the period who were given at least one diagnosis of a psychotic disorder. A total of 317 patients with six or more visits (frequent visitors) were compared with 968 patients with between two and five visits (occasional visitors). RESULTS: Frequent visitors were significantly more likely to be single and homeless and to have diagnostic variability, substance use disorders, and personality disorders. A total of 177 patients experienced diagnostic variability, which was found mainly in three diagnostic categories: schizophrenia, schizoaffective disorder, and bipolar disorder with psychotic features. CONCLUSIONS: Future studies should further examine the link between increased use of emergency services and diagnostic variability.

RESUMEN

OBJECTIVE: The aim of this study was to identify factors associated with homelessness status among patients admitted to the psychiatric emergency ward of a French public teaching hospital over a six-year study period (2001-2006). METHODS: The study was based on a retrospective review of the psychiatric emergency ward's administrative and medical computer databases. Each emergency care episode had accompanying data that included demographic, financial, clinical, and management information. RESULTS: During this six-year study, the psychiatric service recorded 16,754 care episodes for 8,860 different patients, of which 591 were homeless (6.7%) and 8,269 were nonhomeless (93.3%). The mean+/-SD number of visits to the psychiatric emergency service was higher for homeless patients (4.9+/-12.3) than for nonhomeless patients (1.7+/-2.4) (p<.001). A total of 331 homeless patients (56.0%) had more than one care episode, whereas 2,180 (26.4%) of nonhomeless patients had more than one care episode. Factors associated with homelessness included being male, being single, and receiving financial assistance through government social programs. Schizophrenia (43.7%) and substance use disorders (31.0%) were the most common disorders among homeless patients. Aggressive behavior and violence were reported equally among homeless patients (3.5%) and nonhomeless patients (3.2%). Homeless patients were less likely than nonhomeless patients to be hospitalized after receiving care in the emergency ward (47.8% versus 51.1%) (p=.002). CONCLUSIONS: Although there is near-universal access to free mental health care in France, study findings suggest that the quality and adequacy of subsequent care are not guaranteed. Multidisciplinary and collaborative solutions are needed to improve the management of mental health care for homeless patients.

RESUMEN

In Parkinson's disease, dopamine dysregulation syndrome (DDS) is characterized by severe dopamine addiction and behavioral disorders such as manic psychosis, hypersexuality, pathological gambling, and mood swings. Here, we describe the case of 2 young parkinsonian patients suffering from disabling motor fluctuations and dyskinesia associated with severe DDS. In addition to alleviating the motor disability in both patients, subthalamic nucleus (STN) deep brain stimulation greatly reduced the behavioral disorders as well as completely abolished the addiction to dopaminergic treatment. Dopaminergic addiction in patients with Parkinson's disease, therefore, does not constitute an obstacle to high-frequency STN stimulation, and this treatment may even cure the addiction.
