Active clinical trials for "Depressive Disorder, Major"

The investigators propose to answer the following research question: Does a multifaceted, culturally tailored intervention that focuses on the specific concerns and preferences of African American patients with depression and their primary care providers improve the processes and outcomes of care for African Americans to a greater degree than a standard state-of-the art depression intervention? This study will determine whether two new educational programs can improve the care for depression in African Americans. These programs may include visits with a depression case manager and access to educational materials, such as a videotape, a calendar, pamphlets, and books. One program is a standard quality improvement program for depression that has been shown to be effective in most patients. The other program is similar, but has materials that focus more on the patient's specific culture, beliefs, values, and preferences.

This study will explore whether the use of a medication, Ketamine, can help patients who come to the ER with thoughts of suicide by improving their mood and reducing thoughts of suicide. Ketamine has been used for this purpose in patients who have been hospitalized, but it has not been well studied in the ER. The investigators are first trying to show that patients and doctors in the ER find the treatment acceptable. The investigators also hope to determine whether Ketamine is effective in decreasing the severity of patient's suicidal thinking while in the ER. If this treatment works, future studies will look at whether it can help patients be discharged from the hospital earlier. Research Procedures: Patients will be enrolled into the study on a voluntary basis after the research assistant has fully explained all the risks and benefits of the study (informed consent). Research assistants, Emergency Department staff, and the Psychiatry team will help identify patients for the study. Patients will be asked to complete surveys measuring the degree of their suicidal thinking and mood. Additional information will be collected on patients such as their demographics, current medications, and medical problems. Patients in the study will receive the medication, Ketamine, which will be given through an intravenous catheter (IV) at a dose based on the patient's weight and slowly infused over 40 minutes. Patients will be monitored during their stay in the Emergency Department by Emergency Department physicians and nurses for any signs of side effects to the medication. Patients will be asked to complete several surveys at specific time periods after the administration of Ketamine. All patients in the study will receive usual psychiatric care in addition to the study medication.

In this study the investigators will submit patients with treatment resistant depression to deep anesthesia with isoflurane to get 15 minutes of cortical burst suppression on electroencephalogram, once a week for six weeks. The follow up will be for 6 months. The aim is to evaluate the change in depression severity during the entire period.

This study will determine the effectiveness and safety of S-Ketamine in depression patients undergoing electroconvulsive therapy.

Study of tDCS intervention on motivational anhedonia of Major Depressive Disorder

Ketamine hydrochloride, an anesthetic medication, has been demonstrated to acutely and rapidly improve depressive symptoms but not yet been adequately studied for this effect when used as part of a general anesthetic for surgery. This proposed single-centre, double-blinded, randomized clinical trial of adult patients with depression presenting for gynecologic surgery would compare severity of depressive symptoms between patients receiving and not receiving ketamine as part of their general anesthetic.

Lithium is a mainstay in the treatment of bipolar disorder, and a frequently used adjunctive therapy for major depressive disorder. It is accepted practice to monitor lithium serum levels to monitor for efficacy and toxicity. However, studies on the difference in lithium levels between once and twice daily dosing, which also assess the impact of kidney function are scarce. The aim of this study is to quantify this pharmacokinetic difference, identify the impact of kidney function, in the context of estimating effects to inform feasibility and sample size needed for a larger well-powered study.

The purpose of this study is to assess safety and efficacy of nodal transcranial direct current stimulation in pediatric and teenager population with major depressive disorder in the COVID-19 pandemic.

Sumor is a food supplement that combines the main coenzymes of the S-Adenosyl methionine (SAMe) cycle, namely vitamins B6, B12 and folate, with SAMe and betaine. Sumor also contains vitamin C, a molecule that has shown promise in the treatment of depression in experimental models, and selenium, an antioxidant agent whose blood deficiency has been associated with depressive symptoms in some preliminary studies. There are no studies in the literature on the efficacy of this combination in the adjuvant therapy of depression. The purpose of this study is to compare the effects of Sumor in co-therapy with an SSRI antidepressant versus co-therapy with placebo in patients with treatment-resistant Major Depressive Disorder.

The aim of the study is to test the efficacy of a treatment for depression based on interpersonal psychotherapy (IPT). The treatment will be accessed via an internet platform built for this study. A therapist will provide support weekly, as well as on-demand when needed. The treatment lasts for 10 weeks.
