Apathy in Late Life Depression: New Biomarkers Using Actimetry and Magnetic Resonance Imaging
DepressionOld age (> 60 years) is at high risk to develop major depression disorders (MDD). MDD doubles the risk for subsequent cognitive disorders and dementia. Apathy (i.e. the lack of motivation) is a core problem in depression in older age and is frequently associated with cognitive decline in people who have mild cognitive disorders. The investigator propose here to combine actimetry (the measurement of motor activity using a simple device worn at the wrist) and brain imaging to show that it's possible to measure apathy using actimetry in a population of elders with MDD. Having shown that apathy can reliably be measured with actimetry and that it is associated with brain abnormalities, the investigator will be able to test whether actimetry can predict cognitive decline in elders with MDD and can be routinely used in a day-to-day medical practice.
Intervention to Prevent Peer Violence & Depressive Symptoms Among At-Risk Adolescents
Depressive DisorderViolenceThe purpose of this investigation is to test the efficacy of "iDOVE2" (a brief emergency department introductory session and longitudinal automated text-message depression prevention program for high-risk teens), and to determine the most potent and parsimonious combination of intervention components for preventing peer violence and depressive symptoms among at-risk youth.
Role of Self-focused Attention in Depression
DepressionUsing a task measuring the tracking of eye movements, the aim of this study is to demonstrate that individuals suffering from depression focus their attention more on their reflection in the screen after recalling a failure (and this all the more so as their depressive symptomatology is strong) .
Retrospective TMS Therapy for Adults With MDD
Major Depressive Disorder (MDD)Examine change in the magnitude of antidepressant effects as a function of number of TMS sessions and to determine whether extended treatment courses, beyond 30 and beyond 36 TMS sessions, result in improved efficacy.
3-year Follow-up of the Mind My Mind RCT
Emotional ProblemAnxiety Disorder of Childhood3 moreThis is a three-year follow up of a previously completed randomized clinical trial (RCT) of a transdiagnostic cognitive and behavioral (CBT) program ("Mind My Mind" [MMM]) compared to management as usual (MAU) in youth with emotional and behavioral problems. The effectiveness trial (Clinical Trials Identifier: NCT03535805) evaluated an intervention for help-seeking youth with emotional and behavioral health problems below the threshold for referral to specialized treatment. The experimental intervention MMM consisted of 9-13 weekly, individual therapy sessions delivered by psychologists in a non-specialist school-based setting. The CBT-methods were organized in modules for anxiety, depression and/or behavioral problems, and the therapy was completed within 17 weeks. The MAU was enhanced by two care-coordination visits to help coordinate the usual care in the four municipalities in Denmark. The trial was conducted in four diverse municipalities in Denmark. The aim of this study is to determine the long-term effects of the transdiagnostic, modular CBT program ("Mind My Mind" [MMM]) compared to management as usual (MAU). The three-year follow-up of the RCT of MMM versus MAU is nested in a larger study of help-seeking youth screened for eligibility and stratified into three groups with increasing severity of problems. Youths with an intermediate level of problems were included in the RCT. We screened 573 help-seeking youths, and we included and randomized a total of 396 youths (age 6-16 years, with anxiety, depressive symptoms, and/or behavioral problems) to MMM (n=197) or MAU (n=199). The study participants comprise the 396 youths and their parents who participated in the RCT. We will use the help-seeking population and the background population in the four municipalities as reference groups. The follow-up study does not include an intervention. The long-term outcome of MMM versus MAU will be investigated using parent-reported questionnaires administered in average three years after random allocation to intervention. All study participants are followed in the Danish national registries.
Evaluating an Online Wellness Intervention for Greek Adolescents
Depressive SymptomsAnxiety1 moreThe investigators are evaluating the effects of an online single-session mental health intervention (the Common Elements Toolbox; COMET). To evaluate COMET, the investigators are conducting a randomized controlled trial with Greek adolescents attending high school in the Attica region in Greece. Students will be randomized to the COMET condition or to an active control condition. Primary outcome measures (depressive symptoms, anxiety symptoms, subjective well-being) will be measured at two weeks post-intervention and four weeks post-intervention. The investigators will evaluate COMET as a universal intervention (using the full sample) and as a targeted intervention (analyzing those who reported elevated depressive symptoms or anxiety symptoms at baseline).
The Efficacy and Safety of S-ketamine in Elective Cesarean Section
AnesthesiaAnalgesia3 moreDuring the past years, a large number of clinical trials have investigated the use of the non-competitive N-methyl-D-aspartate (NMDA) receptor antagonist racemic ketamine as an adjunct to local anaesthetics, opioids, or other analgesic agents for the management and prevention of postoperative pain. Actually racemic ketamine not only abolishes peripheral afferent noxious stimulation, but can also prevent the central nociceptor sensitization. S-ketamine, one of two enantiomers of racemic ketamine, has twice the analgesic potency of the racemate. Moreover, S-ketamine shows smaller nervous system and less psychotropic effects than racemic ketamine , which may make the drug more suitable for clinical use. Recently, S-ketamine has been approved to treat refractory depression (TRD) and major depressive disorder (MDD) by the FDA .S-ketamine may have greater clinical significance due to the high rate of maternal depression. Therefore, we plan to explore whether clinical use of S-ketamine can optimize anesthesia protocol and improve maternal prognosis.
