Filter by:Title: "Feasibility and acceptability study of "Mamá, te entiendo": an app-based intervention for reducing depressive symptoms in postpartum women" Funding: This work was funded by the Chilean National Agency of Research and Development (ANID Doctorado Nacional 2019 - 21190745). General objective: To assess the feasibility and acceptability of a guided 8-week cognitive-behavioral app-based intervention for Chilean postpartum women with depressive symptoms. Design: A small-scale parallel 2-arms trial will be conducted. Postpartum women with minor or major depression will be randomized to the app-based intervention or waitlist. The primary outcomes are feasibility and acceptability variables, mainly; recruitment and eligibility rates, intervention and study adherence, and participants' intervention satisfaction, use, and engagement. Semi-structured interviews with a sub-sample will provide more information about the participants' experience with the intervention. Women's depression diagnostic status will be assessed at pre-treatment, post-treatment, and 1-month follow-up. Other secondary outcomes will include participants' perceived social support, mother-infant bonding, and maternal satisfaction and self-efficacy.
The investigators have developed an integrated suicide intervention, Brief Suicide and Trauma Therapy (BSTT). BSTT combines Brief-Skills for Safer Living (Brief-SfSL)-a promising method to enhance coping skills and reduce suicidality-with a trauma therapy component to alleviate the specific impacts of childhood trauma on suicide risk. The aim of this pilot is to test 12-weeks of BSTT to alleviate suicide risk among individuals with a history of childhood trauma and current suicidality.
Schizophrenia, bipolar and major depressive disorders collectively affect over 10 million people across the EU and are associated with annual healthcare and societal costs in excess of 100 billion Euros. When diagnosed with one of these disorders, patients are prescribed psychotropic medication such as antidepressants, mood stabilisers or antipsychotics. It is unknown whether this first-line treatment will be successful. After this first-line treatment fails, usually a second-line treatment is initiated, and when this is not successful either a third-line treatment is initiated. Third-line treatments are quite successful, especially when compared to second-line treatments. The research question is whether the third-line treatments (early-intensified treatments) would be more efficacious than the current second-line treatments (treatment as usual) for schizophrenia, bipolar and major depressive disorders. If this is indeed the case, this could lead to the prevention of unnecessary trials of ineffective treatments and adaptations of worldwide guidelines as well as a reduction of healthcare and societal costs.
Major depressive disorder (MDD) is the world's leading cause of disability according to the World Health Organization. MDD is highly recurrent, even if clinical remission is reached after successful treatment. In fact, the enormous burden of disability, mortality and financial costs is due to the recurrent and chronic nature of MDD. The reliable prediction of the recurrence of major depressive episodes (MDEs) based on a prognostic model that is informed by biological, neurophysiological or neuroimaging data would be valuable and lifesaving for many. However, such models are still lacking. Several lines of evidence point to abnormal prefrontal control over limbic emotion processing areas in MDD owing to diminished prefrontal excitability that seems to persist during MDD remission (rMDD). Prefrontal excitability in rMDD may thus be a trait marker of MDD and may potentially be indicative of disease recurrence. Yet, research investigating the potential utility of prefrontal excitability for predicting the recurrence of MDEs is lacking. Cortical excitability can be investigated using transcranial magnetic stimulation (TMS); however, human studies have mostly probed cortical excitability of the motor cortex, a brain region not considered to be central in the neuropathology of MDD. Hence, knowledge of the effect of TMS on prefrontal excitability is limited. Moreover, whether immediate prefrontal modulation by TMS can predict the recurrence of MDEs in fully remitted MDD patients remains to be investigated. Thus, there is a need for research that aims to quantify the direct and immediate aftereffects of TMS on prefrontal function. Most importantly, with regard to precision medicine, there is a need for research that explores the utility of immediate prefrontal reactivity to TMS for predicting MDE recurrence. Here, the investigators propose a research program that will exploit the combination of functional near-infrared spectroscopy (fNIRS) with brain stimulation. Concurrent theta-burst stimulation (TBS)/fNIRS measurements will allow us to systematically investigate stimulation-induced modulation of blood oxygenation as a proxy for induced brain activity changes (TBS is a modern form of patterned TMS). The findings from this study will (1) elucidate the immediate effects of excitatory and inhibitory brain stimulation on prefrontal activity in rMDD and controls and (2) validate the potential utility of stimulation-induced brain modulation for the prediction of MDE recurrence.
One in five people will present a major depressive episode (MDE) in their lifetime. While antidepressants (ADs) are currently the standard treatment for MDE, the first AD prescribed is effective in less than 40% of patients and a complete clinical response is only observed after several weeks. Identifying early biomarkers of the response to treatment with an AD could allow the clinician to rapidly identify patients in whom treatment will not be effective and therefore modify patient care. We have recently shown that the messenger RNA (mRNA) of two proteins, ELK1 and GPR56, were present in different amounts in the blood cells of "responder" compared to those of "non-respondent" patients. In this context, our main objective will be to determine whether ELK1 and GPR56 mRNAs, are very early biomarkers of the response to AD, i.e., biomarkers whose variation precedes the clinical response by several weeks. Secondary objectives will be to identify early phase changes in neurophysiological measures, cognitive and behavioral tasks, as well as levels of blood coding and non-coding RNAs, serum cytokine, mitochondrial and metabolic markers, neuroimaging markers as biomarkers of differential treatment outcomes to antidepressant treatment. Patients will be treated with SERTRALINE or FLUOXETINE or DULOXETINE or MAPROTILINE (in monotherapy) with or without adjunct benzodiazepine. Patients are identified as responders or non-responders based on their clinical assessment at 8 weeks after treatment onset. In addition, a second stage will collect data to address another important issue for the management of patients with a MDE: to discriminate those with a major depressive disorder (MDD) from those with a bipolar disorder (BD). BD diagnosis is one of the most common reasons of failure to response to ADs. Therefore, one of our secondary objectives will be to identify biomarkers to differentiate between these two categories of patients. To do this, we will follow patients for a period of 24 months to identify those who will present during this follow-up the diagnostic criteria of bipolarity.
Depression is a leading cause of disability worldwide and is more commonly seen in individual's post-spinal cord injury (SCI) than in the general population. Depression post-SCI impacts an individuals' quality of life and recovery. It has been reported that among Veterans with an SCI, those without depression live longer than those with depression. Thus, depression must be treated appropriately. Repetitive transcranial magnetic stimulation (rTMS) is an FDA-approved treatment for depression, but dosing is based on a motor response or movement in the thumb. Over half of individuals with SCI have some degree of arm or hand impairment, so these individuals might not be eligible for rTMS, or they may receive the wrong dose. This study proposes clinical trial in individuals with depression post-SCI to assess the anti-depressant effect of a novel technique to dose rTMS that does not require a motor response in the thumb. By gaining a better understanding of the application of rTMS for depression post-SCI, the investigators aim to advance the rehabilitative care of Veterans.
The POKAL-PSY project is a study that monitors participants for five years. The goal of the study is to identify distinguishable subtypes of depression on the basis of biomarkers and to gain insight into their prognostic significance.
Depression is a leading cause of disability worldwide and poses a large economic burden in the UK. There is evidence that exercise is beneficial in the management of depression and NICE now recommends group exercise programs as a treatment for people with mild and moderate-severe depression. Research shows that patients with severe depression are less likely to engage in exercise than patients with mild to moderate depression. There is little evidence, however, on the barriers and drivers to participation in such programs experienced by patients with depression; leading to uncertainty in the most effective way to implement these programs. We aim to analyse accounts of patients who have been referred to or participated in the Exercise Recovery Group (ERG), a group exercise program at the Nottingham Specialist Depression Service (NSDS). The NSDS is a tertiary unit where referred patients have suffered moderate-severe, persistent clinical depression. Eligible participants will be patients with persistent major depression who have agreed to referral to the ERG at the NSDS and who are able to provide informed consent. Participants will undergo a one-off 60 minute meeting via MS Teams, including an in-depth semi-structured interview on their experience as well as self-completion questionnaires assessing demographics, depression, anxiety and shame. Transcripts of the interviews will be subject to qualitative thematic analysis addressing questions on barriers and drivers of exercise treatment in depression; and the perceived impact of an exercise group on the individual participating. Themes will be developed to give an account of these questions, supported by anonymised quotes from the transcripts. The questionnaire data (on demographics, depression, anxiety, shame) will be used to characterise the group, in order to help assess directness of the evidence provided for other clinical populations; ultimately helping clinicians to implement exercise groups for depression that are acceptable for patients.
There are many common pharmacological treatments for major depression disorder (MDD), however the efficacy of these drugs often fails in severe cases. Intravenous (IV) administered ketamine may offer the potential for remission of the symptoms in patients with MDD; however it has not yet been approved by FDA for this purpose. This study will make use of an electroencephalography (EEG) machine to measure the brain's activity and response while the IV ketamine is being delivered. The objective of this study is to characterize the change in EEG response of patients with MDD, during and 4 weeks after a course of IV ketamine infusions.
70% of Europeans will be exposed to a potentially traumatic event (PTE). Following this experience, people are likely to develop various psychiatric disorders such as post-traumatic stress disorder (PTSD) or a major depressive episode (MDE). However, not all subjects have the same risk to develop a pathology, and resilience capacities, which depend on multiple factors are difficult to predict. Currently, there are no objective tools to stratify exposed subjects according to their risk of developing pathological responses to stress, which leads to difficulties in allocating means of prevention and treatment. Recently, new biological hypotheses explaining vulnerability/resilience to stress and depression, implicating the GPR56 and ELK1 genes, have been described. Previous studies have shown that evaluation of the vulnerability risk can be obtained from clinical, cognitive, biological or brain imaging variables, but no study has integrated these different approaches. Therefore, the project presented here aims at integrating behavioral, biological and neuroimaging data to predict the development of psychiatric disease. In this study, a prospective cohort of 255 violent trauma victims will be set up in 3 French cities for a period of 2 years. Eligible subjects will be included in the month following PTE and will be followed longitudinally for 12 months. Evaluations at 1, 3, 6 and 12 months will be performed, during which the subject will complete various clinical and cognitive tests. A blood sample will be collected at each visit to study biological processes including the regulation of genetic and epigenetic expression, in particular the expression of the GPR56 and ELK1 genes in the blood. For eligible subjects a brain MRI will be proposed at the first visit. We hypothesize that the genetic expression of ELK1 and GPR56 is predictive of the development of psychiatric pathologies at 6 and 12 months post-PTE. The ambition of this project is also to highlight the importance of a multimodal approach integrating a triad of markers (behavioral, biological and neuroimaging) to test this hypothesis.
