Effect of Low-dose Esketamine on Maternal Depression at 2 Years After Childbirth
Prenatal DepressionKetamine1 morePostpartum depression refers to the depression after childbirth, which is a common mental disorder in women. The pathogenesis of postpartum depression is not fully understood, and may be related to a variety of factors. Prenatal depression is an important risk factor for postpartum depression. Our recent multicenter randomized controlled trial, "Effect of Low-dose esketamine on the incidence of postpartum depression in women with prenatal depression", explored the effect of immediate postpartum intravenous infusion of low-dose esketamine on the incidence of postpartum depression in women with prenatal depression. The preliminary results showed that it reduced the incidence of postpartum depression at 42 days. Since there were no studies on the effect of intravenous esketamine infusion after delivery on long-term postpartum depression, this study is a long-term follow-up of the previous randomized trial. We aim to explore the effect of low-dose intravenous esketamine after delivery on the incidence of 2-year maternal depression after delivery in women with prenatal depressive symptoms.

Accessing Innovative Mental Health Services for Depression in Vietnam
DepressionAnxiety DisordersThis stepped wedge, randomized controlled trial (RCT) will test the effectiveness of a digital mental health intervention (VMood) adapted from an evidence-based in-person intervention. The in-person intervention is based on principles of Cognitive Behavioural Therapy and uses a supported self-management approach consisting of a patient skills workbook and supportive coaching by a non-specialist provider. It was developed in Canada and shown to be effective in the Vietnamese context in a previous RCT conducted by the research team. The digital adaptation (VMood) is delivered via a Smartphone app the research team developed in Vietnam, in close collaboration with the Institute of Population, Health and Development (PHAD) in Vietnam. The digital intervention will be delivered at the community level in 8 Vietnamese provinces, with remote coaching provided via the app by social workers. The primary outcome measure for the study is the Patient Health Questionnaire (PHQ-9), which screens for depression caseness. The investigators will also include the Generalized Anxiety Disorder(GAD-7) measure, as symptoms of anxiety commonly co-occur with depression. Secondary outcome measures will include the WHO Quality of Life-Brief (WHOQUAL-BREV), FAST Alcohol Screening Test (FAST), the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) adapted to assess tobacco use only. The investigators will also conduct a cost-effectiveness analysis (CEA) using the 5-level EQ-5D (EQ-5D-5L), the Health Economic Assessment (HEA) adapted for the Vietnamese health context, and Work Productivity and Activity Impairment Questionnaire: Depression (WPAID:D). Finally, the System Usability Scale (SUS) will be used to assess VMood usability.

Gut Microbiome and Depression
Multiple SclerosisDepressionThe purpose of this project is to determine if specific gut microbiome or gut-derived metabolites are associated with depression in patients with Multiple Sclerosis (pwMS). Mechanistically, the investigators further hypothesize that depression in pwMS is related to decreased abundance of gut bacteria with GABA-producing activities and/or with anti-inflammatory properties. To determine if the presence of depression in pwMS is associated with specific gut microbiome, gut-derived metabolites or peripheral blood immune profiles. The investigators will perform a cross-sectional study in clinically stable pwMS recruited at the John L. Trotter MS Center. The investigators will evaluate the presence of depression using the Quality of Life in Neurological Disorders (Neuro-Qol) depression scale, one of the 13 scales in the Neuro-Qol recently developed by the NIH using modern psychometric techniques and validated in pwMS. A total of 120 pwMS will be recruited: 60 with and 60 without depression based on the Neuro-Qol depression scale. At the study visit each participant will be asked to provide a stool sample for microbiome analyses and a blood sample for peripheral blood immunophenotyping. Potential confounders will be collected and treated as covariates in the analyses. These include: 1) degree of disability (EDSS); 2) treatment with anti-depressants and DMTs; 3) a 4-days food diary to evaluate diet composition; 4) weight and height to calculate the BMI; 5) fatigue; 6) level of physical activity; 7) sleep quality.

Improving Health Care in Major Depressive Disorder
Major Depressive DisorderThis project aims to improve the health care provided to people with major depressive disorder (MDD), a disease which is a top cause of disability worldwide. One of the main obstacles to a more effective health care in these patients is represented by clinical heterogeneity, which has not completely elucidated biological correlates. Using a large sample of people with MDD already recruited (n=29,400), the investigators develop a clustering algorithm based on genetic-environmental and brain imaging predictors aimed at identifying homogeneous MDD subgroups. The researchers will then link these subgroups with relevant health outcomes, such as disease recurrency and severity, well-being and functioning, risk of psychiatric and medical comorbidities (e.g. cardiovascular disorders). Replication in independent samples already recruited(n=1380) will prove the validity of the subgroups and expand their clinical characterization. The investigators will develop a classification tool to link the individual's characteristics to the relevant health outcomes and provide corresponding clinical recommendations. The prognostic support tool will be applied to newly recruited samples, feasibility and usefulness according to clinicians's opinion will be assessed (n=120, ongoing recruitment).

OcupApp: Occupational Self-analysis Intervention Through an Mobile Application
Anxiety DisorderDepressive Disorder2 moreThe goal of this clinical trial is to test the effectiveness of the use of mobile application ("OcupApp") to generate a personal self-analysis about meaningful activities in which adults between the ages of 50 and 70 with anxiety and subclinical depression participant. A randomized study will be carried out comparing the effects of the use of the application "OcupApp" with a control intervention on the quality of life related to health, mental health, frequency of participation on meaningful activities, and perceived occupational balance.

Adaptation of Individual Dialectical Behavior Therapy Intervention for Transdiagnostic Treatment...
Anxiety DisorderDepressive DisorderAnxiety and depressive disorders, referred to as emotional disorders, have high rates of prevalence, recurrence, and functional impairment. Transdiagnostic psychotherapy targeting shared features of these disorders has recently emerged. Dialectical behavior therapy (DBT) for the transdiagnostic treatment of emotional disorders is a promising approach, as results of preliminary studies for use in a broad range of mental disorders are encouraging. Since there is a lack of research on transdiagnostic psychotherapy in Taiwan, the investigators thus propose this 3-year randomized controlled trial to test the efficacy of a modified DBT for the treatment of transdiagnostic emotional disorders and to further evaluate whether the efficacy of modified DBT differs in the specific emotional disorders. The investigators expect that patients with emotional disorders receiving modified DBT are more likely to improve clinical outcomes, functioning, and quality of life.

Real-life Assessment of Brexpiprazole (Rexulti) in Schizophrenia and in Depressive Disorders
PsychosisDepressionNot only being the mainstay of treatment for schizophrenia spectrum psychotic disorders, antipsychotics, especially the second-generation antipsychotics (SGAs) have also been recommended as augmenting agents for treating depression. Dopaminergic agents, including both dopamine D2/D3 antagonists and dopamine partial D2 agonists, have been effective for treating psychosis and schizophrenia. Amongst all SGAs, those with partial D2 agonistic property are generally acknowledged to have better side-effect profiles with lower incidence of extrapyramidal side-effects, prolactin increase, weight gain, QTc prolongation, and metabolic syndrome, as well as more efficacious in alleviating depressive symptoms. Up-to-date, three SGAs, namely aripiprazole, brexpiprazole and cariprazine, are known to possess such partial D2 agonism. ReSD-HK study is part of the ReSD Asian Study aiming to carefully evaluate a cohort of patients prescribed with brexpiprazole on its efficacy and tolerability as treatment for schizophrenia and/or depression in a real-life clinical setting.

Dutch-Depression Outcome Trial Comparing 5 Day Multi Daily Neuronavigated Theta Burst Sessions With...
Treatment Resistant DepressionINTRODUCTION Recent findings from three small studies (total n=59) suggest that three changes in repetitive Transcranial Magnetic Stimulation (rTMS) protocols, called the Stanford Neuromodulation Therapy (SNT) protocol, contribute to extreme high overall remission of 79% in patients with treatment resistant depression (TRD), whereas remission using a standard 10 Hz rTMS protocol is 25%. The improvement using the SNT protocol is achieved by combining 1) accelerated treatment with multiple sessions per day, 2) applying a higher overall pulse dose of stimulation, using intermittent Theta Burst Stimulation (iTBS), and 3) precise targeting of the region in the left dorsolateral prefrontal cortex (DLPFC), using functional MRI guided neuronavigation. OBJECTIVE To determine if the SNT protocol is more (cost-) effective compared to standard 10 Hz rTMS in patients with TRD, even though the number of pulses given in both protocols is equal, i.e., 90,000. STUDY DESIGN Multicenter randomized controlled trial comparing SNT with standard 10Hz rTMS with a follow-up of 25 weeks. STUDY POPULATION 108 Patients with TRD (no response to 2 or more evidence-based treatments). INTERVENTION 50 sessions using the SNT protocol in 5 days. The region of the left DLPFC most anticorrelated with the subgenual anterior cingulate cortex in each participant will be targeted based on subject-specific functional resting state MRI. COMPARISON 30 standard daily 10 Hz rTMS sessions in six weeks, targeting the left DLPFC based on standard measurement procedures of the skull. OUTCOME MEASURES Remission, based on the Hamilton depression rating scale Cost effectiveness, based on healthcare resource use Quality of life and positive mental health Tolerability and safety Relapse Description of opportunities and difficulties with regard to implementation SAMPLE SIZE The investigators will enrol 108 patients (α=0.05, power is 0.80) including adjustment for attrition. COST EFFECTIVENESS ANALYSIS SNT is faster and possibly more effective than 10Hz rTMS leading to a total cost reduction of 22 million each year considering less expensive healthcare, reduced illness duration and absence from work. TIME SCHEDULE Within 36 months, the investigators will recruit and treat 108 patients with TRD: each center will recruit 9 patients per year. After the last follow-up assessments, the investigators will finalise the study within 12 months and report the results.

Minor Depressive DisorderMajor Depressive Disorder1 moreTitle: "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.
