Perinatal depression is a common and serious mood disorder that increases morbidity and mortality in new mothers and results in poor infant/child outcomes. Current therapies often fail to produce recovery or are poorly tolerated and many pregnant women seek non-pharmacologic therapy or forgo treatment when non-pharmacologic options are not available. Expectant and new mothers who suffer from circadian rhythm disruption are at risk for perinatal depression. This R34 Pilot Effectiveness Studies and Services Research Grant seeks to test whether an Integrated Chronotherapy (IC) intervention can be implemented in an outpatient psychiatry setting to improve treatment outcomes for patients with perinatal depression. IC is a multicomponent treatment consisting of bright light therapy, sleep phase advance, and sleep stabilization/restriction that targets the Research Domain Criteria (RDoC) constructs of circadian rhythms, sleep-wake behavior, social rhythms, and arousal. We will assess the feasibility, safety, and acceptability of an IC intervention for perinatal depressin by testing the treatment in expectant mothers diagnosed with major depressive disorder during 3rd trimester of pregnancy. We will randomize patients to either: (a) usual care (UC, n = 20) or (b) IC+UC (n = 20). IC+UC will have pregnancy and postpartum components and will be administered via an individualized case formulation approach tailored to each patient. After a baseline assessment, IC will be prescribed during 5 dedicated clinical visits: three during 3rd trimester of pregnancy and 2 in the postpartum period. UC will consist of medication administered by a perinatal psychiatrist and/or psychotherapy. UC will be quantified in both groups to evaluate differences between the IC+UC and UC groups. Mood will be measured in both groups by blinded clinician interview and patient self-report. We will assess the safety profile of the IC intervention with evaluation of side effects/adverse events. Importantly, the study will also examine the putative mechanisms by which IC is hypothesized to work and the "dose" of IC received by patients in the IC+UC group. All participants will wear wrist actigraphy/light monitors continuously during weeks 28-40 of pregnancy and postpartum weeks 2-6 to assess light exposure and sleep duration and timing. Circadian phase (measured with salivary dim light melatonin onset) will be measured at baseline during pregnancy (~30 weeks gestation), at 36 weeks gestation, and at postpartum week 6. This pilot will allow us to refine the IC intervention for future integration into various clinical settings and establish an infrastructue for a larger (R01-scale) trial, including measuring acceptability of IC among UC clinicians and implementing web-based data collection to facilitate data sharing in the planned R01. Perinatal IC could have major public health impact due to the high prevalence of perinatal depression and its negative effects on mothers and their children. This project represents a first step toward achieving this goal, as it will provide the pilot data necessary to prepare for a larger scale intervention study focused on providing non-pharmacologic therapies and improving outcomes for women with perinatal depression.
Predictive factors and biomarkers of response to antidepressants in major depressive disorder are scarce. Beta-arrestins are proteins which inhibit G Protein Coupled Receptors and desensitize serotonergic and dopaminergic receptors. The study hypothesis is that Beta-arrestins 1 and 2 are predictive factors and biomarkers of response to antidepressants in major depressive disorder. In a controlled prospective open naturalistic monocentric 3-month study, 60 patients with a major depressive disorder requiring a treatment with venlafaxine will be included and assessed before treatment, 1 month and 3 months post-treatment. 20 controlled healthy subjects matched for age and gender will also be assessed. The Beta-arrestin pathway will be assessed using genetic polymorphisms, Peripheral Blood Mononuclear Cell measures and functional pathway. Antidepressant response will be assessed using depression scales, olfaction and memory as surrogate markers of neurogenesis.
1. Investigate the safety and effectiveness of a single dose of IV Ketamine for adolescents with suicidal ideation and depression. It is hypothesize that Ketamine will be well tolerated and significantly reduce depressive symptoms and suicidal ideation. 2. Explore whether decision making as measured by the Iowa Gambling Task changes before and after Ketamine infusion. It is hypothesize that IV Ketamine infusion will significantly improve the decision making ability a measured by the Iowa Gambling Task in adolescents that are suicidal.
The objective of the study is to examine whether a combination of wake therapy, light therapy and sleep time stabilization as a supplement to standard treatment can reduce depressive symptoms in patients admitted at two psychiatric wards at Aarhus University Hospital, Risskov. Seventy-four patients will be randomized either to this intervention or to a control group receiving treatment as usual. Furthermore, it will be examined whether the duration of admission can be reduced in the intervention group. Finally, the aim is to identify predictors of good effect of the intervention.
To evaluate the efficacy and the safety of ASC-01 (aripiprazole/sertraline combination) compared to sertraline monotherapy in patients with major depressive disorders who have responded incompletely to sertraline monotherapy.
We propose a clinical study of medial forebrain bundle DBS as a treatment in 20 patients with treatment refractory depression (TRD). Data from the University of Bonn indicates that surgical lesions of the medical forebrain bundle can produce therapeutic benefits in patients with depressive disorders, and suggest that DBS at the same site may also reduce symptomatology in these TRD patients (Schaepfer, 2013). Depression affects up to 10% of the US population and of those at least 10-15% do not benefit from therapies hence why we must explore new treatments. The Percept™ PC system manufactured by Medtronic Neurological will be used in this study. Study subjects will be between the ages of 22 and 70 years of age and suffer from TRD, have failed multiple treatment regimens, including ECT, and remain symptomatic. Those identified as TRD patients will then be enrolled in a clinical pilot study investigating DBS, targeting the MFB.
Bupropion hydrochloride was first approved on 30 December 1985 in United States for depression and is currently approved in 80 countries. Bupropion has also subsequently been approved for smoking cessation and for seasonal affective disorder. Cumulative exposure to bupropion is estimated at approximately 97.3 million patient exposures up to 31 December 2012. Bupropion hydrochloride is a weak catecholamine reuptake inhibitor predominantly affecting serotonin, norepinephrine and dopamine. Its mechanism of action and its structural similarities to diethylpropion, amphetamines, and cocaine, bupropion resembles stimulants in many respects, leading to concerns about potential abuse of the product. Abuse potential had been part of the Benefit Risk Management Plan for bupropion up until 2003 and at that point, had no longer been regarded as a potential risk that required additional/further evaluation outside standard pharmacovigilance monitoring. The current European Risk Management Plan also states that standard pharmacovigilance monitoring applies to abuse potential. Monitoring has shown a recent increase in the number of spontaneous reports from the Adverse Event reporting System (AERS) of drug abuse. The bupropion team agreed that although the numbers of abuse reports was small relative to the total number of reports for bupropion in OCEANS, there was sufficient information in AERS to warrant investigation of the potential effect on public health. To investigate the degree of misuse and abuse of bupropion (including non-oral routes of administration) in the United States, the Drug Abuse Warning Network will be used to examine the study period 2004-2011.
The primary hypothesis of this confirmatory study is that lithium therapy will acutely decrease suicidal ideation and/or suicidal behaviour in inpatients with a major depressive episode (MDE, unipolar and bipolar disorder according to DSM IV criteria). The specific aim is to test the hypothesis that lithium plus treatment as usual (TAU), compared to placebo plus TAU, results in a significantly greater decrease in suicidal ideation and/or behaviour over 5 weeks in inpatients with MDE.
Suicide attempts are a serious concern worldwide. Currently, existing drugs take about three weeks to show effect on suicidal thoughts and drives. Recent evidence suggests that intravenous Ketamine exerts a rapid effect in suicidal patients, even after a single injection. We aim to examine whether oral Ketamine is a safe and effective treatment in suicidal patients. Following a suicide attempt, patients will be randomized into a group that will be given Ketamine for 21 days and one that will receive placebo, and assessed using questionnaires and brain scans. We expect early improvements in suicide scales in the Ketamine group. As a secondary goal, this study will use IV ketamine in order to access the extent to which the experience of the embodied self mediate different levels of "embodied emotion". A better understanding of these relations will assist in unveiling the cognitive mechanism underlying the therapeutic effect of ketamine
