Predictors of Treatment Response in Late-onset Major Depressive Disorder
Depressive DisorderMajorDepression is a common disorder, especially in old age, where it is associated with significant morbidity and mortality. This study will investigate whether there are features of individual patients with major depression that may predict positive treatment response. The study will invite 40 patients who have been diagnosed with major depressive disorder with onset after the age of 60 years to participate. Participants will be recruited from the Mental Health of Older Adults services at the South London and Maudsley NHS Mental Health Foundation Trust. Participants will receive usual treatment as set out in standard Care Pathways, used by the clinical care team. As part of the study, they will undergo a short battery of neuropsychological tests and a standard MRI brain imaging protocol. The neuropsychological tests and assessment of depression severity will be carried out twice (at Baseline and Week 12). Data will be analysed to investigate whether there are features specific to those patients who show a good response to antidepressant treatment after 12 weeks. Identification of such predictors may help to stratify treatment approaches in the future and lead to the early identification of individual patients who may require alternative treatment approaches to standard antidepressants.

Development, Feasibility and Acceptability of Fathers and Babies (FAB): A Pilot Study
Perinatal DepressionPostpartum Depression1 moreDuring this project the investigators will develop and pilot test a companion intervention for fathers (Fathers and Babies-FAB), to supplement the Mothers and Babies Course (MB) that provides stress and mood management tools for home visiting clients. Focus groups with prior study participants, their male partners, and home visiting staff will be used to develop the FAB curriculum and protocol. FAB text messages aim to improve the mental health of the male partner and help him support his partner's mental health. Feasibility, acceptability, and outcome measures will be supplemented with assessments of fathers' mental health and partners' relationships. Participant assessments will be conducted at baseline, 3 and 6 months in this uncontrolled pilot study. The public health significance and innovation of this project is substantial. If the investigators are able to integrate MB-TXT and MB-DAD into home visiting programs and generate improved mental health outcomes for home visiting clients and their partners, the investigators will be prepared to replicate this intervention across home visiting programs nationally at a time when home visitation as a service delivery model for families with infants and young children is rapidly proliferating through federal funding.

Evaluating the Feasibility of Disseminating a Novel Mobile Platform to Treat Depression
DepressionThe goal of this project is to conduct a pilot study to test the utility of a Natural Language Processing (NLP) clinical messaging tool to improve the reach and the quality (fidelity and competency) of coaches providing behavioral activation (BA) strategies through a mobile mental health app called Personalized Real-time Intervention for Motivational Enhancement (PRIME). This study will improve the reach of clinicians by using a NLP-powered messaging tool, which will ensure fidelity to the BA model and clinicians will have access to real-time clinical information about their patients to guide more targeted treatment (competence). If successful, PRIME could operate as a cost effective tool for clinicians to extend their reach and an accessible treatment for the population of those struggling with depression.

A Study to Decrease Suicidal Thinking Using Ketamine
DepressionSuicideDepression treatment typically is slow acting. Patients presenting with acute suicidality have few immediate treatment options. However, sub-anesthetic doses of ketamine have been now widely tested as a rapid-acting treatment for depression. Gregory Larkin et al at Yale showed this could be applied to suicidal patients, with 14 of 15 participants showing remission of suicidal thinking within 40 min of the administration of ketamine, with 13 showing lasting remission out to 10 days. No serious side effects were reported. This project proposes to conduct a randomized, placebo-controlled trial of this, same intervention in military patients recently hospitalized for suicidal thinking. After being assessed, and giving informed consent, participants would receive 0.2mg/kg ketamine or placebo. Their suicidal thinking, depression, and other symptoms would be monitored acutely for 240 min after drug infusion, and the for lasting changes the next day, at hospital discharge, 2 weeks, and 10 weeks. Potential adverse events will be monitored via the electronic medical record for up to a year.

Vortioxetine in Patients With Major Depressive Disorder and Coronary Artery Disease
Major Depressive DisorderCoronary Artery DiseaseThis is a preliminary, open-label, clinical trial designed to assess the efficacy, safety, and tolerability of vortioxetine for the treatment of major depressive disorder in patients with coronary artery disease. In addition, the study will assess the effects of vortioxetine on heart rate variability in these patients.

Ketamine for Depression Relapse Prevention Following ECT
DepressionDepression affects up to 20% of people in their lifetime and can be a severe debilitating illness. Indeed, the World Health Organisation has estimated that depression will soon be the second leading contributor to the burden of disease worldwide. One of the big problems for patients and doctors is that currently available antidepressant drugs and psychotherapies do not work for 30% of people. However, about 60% of such treatment-resistant patients will recover fully with electroconvulsive therapy (ECT). Even though it was developed over 75 years ago, ECT continues to be the most powerful treatment for severe, often life-threatening, depression. Despite that, we have recently reported that severe depression symptoms return (called a "relapse") in nearly 40% of such responders within six months of completing a course of ECT. Actually, such high relapse rates are seen for all patients with treatment-resistant depression, irrespective of what treatment they have received. There is thus an urgent need for better treatments to prevent relapse and one such possibility is an old drug called ketamine. Ketamine blocks the activity of glutamate, one of the major chemical messenger systems in the brain. Because of this effect it is sometimes used as an anaesthetic but it can also make you feel a bit "high" and so is sometimes abused as a recreational drug. Fortunately, in small doses it is quite safe. Recently, it has been found that ketamine has a remarkably rapid, but brief, antidepressant effect, including reducing suicidal thoughts. We wish to evaluate ketamine as a way to reduce relapse rates in people who have just been treated successfully with ECT for severe depression. Developing such a new treatment, and understanding how it works, would be of tremendous benefit to persons with severe depression, their families, and the wider society.

Mindfulness-Based Cognitive Therapy for the Prevention of Perinatal Depressive Relapse/Recurrence...
Postpartum DepressionPregnancy1 morePregnant women with histories of depression are at high risk of depressive relapse/recurrence during the perinatal period, and options for relapse/recurrence prevention are limited. Mindfulness-based cognitive therapy (MBCT) has strong evidence among general populations but has not been studied among at risk pregnant women. This study is the second phase of a multi-phase project adapting MBCT for perinatal women (MBCT-PD).

Cognitive-behavioral Intervention Via a Smartphone App for Depressive Symptoms in Caregivers
DepressionMajor depression is a common disorder among non-professional caregivers, and it can be disabling and costly. Although there are effective psychological interventions to prevent depression, most of them involve in-person treatment. New technologies have the potential to overcome the barriers this format presents, which limit accessibility to such interventions. The main objective of this project is to evaluate the effectiveness of a cognitive-behavioral intervention in the prevention of depression, administered through a smartphone application (App), both with and without telephone contact through multiconferencing. Secondary objectives are: (a) test the moderating or mediating effect of the variables in the theoretical model underlying the intervention; (b) analyze the variables that are predictors of intervention outcomes; (c) analyze the acceptability and satisfaction with interventions. A randomized controlled trial will be perform. Caregivers with clinically significant depressive symptoms who do not meet the diagnostic criteria for depressive episode will be included. Recruitment of 174 participants is planned, with random allocation to one of the three conditions (58 participants per intervention): (a) a cognitive-behavioral intervention administered via a smartphone App (CCIA); (b) a cognitive-behavioral intervention administered via a smartphone App + telephone contact via conference call (CCIA+CC); (c) attention control group (ACG). Both interventions will be administered in 5 modules via an App for Smartphones and one group additionally will receive telephone contact via conference call in group format during 4 sessions of 30 minutes. These phone sessions will be recorded to assess the therapists adherence to the intervention protocols. All participants will be evaluated at pre and posttreatment, and 1-, 3-, 6- and 12-month follow-up by trained interviewers who will be blind to the aims of the study, the interventions employed, and the group to which any given participant belongs. Incidence of depression will be examined as the primary measure, with secondary measures being depressive symptoms, symptoms related to the model (pleasant activities, negative thoughts and social contacts) and the acceptability of and satisfaction with the intervention.
