Identification of Physiological Data by a Wearable Monitor in Subjects Suffering From Major Depression...
Major Depressive DisorderTo evaluate, over a period of six months, the links between physiological data collected such as electrodermal activity (or Galvanic Skin Response), motor activity measured by accelerometer, heartbeat measured by photoplestimograph and the clinical evaluation performed by the physician, in patients suffering from major depression disorder.
The Effect of Soluble Epoxide Hydrolase (SEH) on Depression
Major Depressive DisorderDepression is the most common mental disease and the second leading cause of chronic disease burden, which is closely related to suicidal behavior. The diagnosis and treatment of depression still lack of effective biological indicators, and about 30% of patients with depression still can not relieve their depressive symptoms after treatment. Previous studies have found that ATP release from astrocytes plays an important role in the occurrence, development and treatment of depression. Epoxy eicosotrienes (eets) are closely related to the function of the nervous system and may be the pathophysiological mechanism of depression. Soluble epoxide hydrolase (SEH) can regulate ATP release by affecting EET degradation, leading to depression like behavior and antidepressant effect, and sEH is closely related to cognitive function of depression.
A Trial of Enhanced Versus Standard Measurement-Based Care Implementation for Depression
Major Depressive DisorderMobile HealthMeasurement-based care (MBC) is an evidence-based practice that incorporates routine outcome assessment using validated rating scales to guide collaborative clinical decision-making. Although MBC results in improved outcomes for patients with major depressive disorder (MDD), there are barriers to its broad implementation in clinical settings. The use of "enhanced" MBC (eMBC), with mobile apps that allow patients to track outcomes and engage in self-management via WeChat, may address some of these barriers. This study intends to compare differences of efficacy between the implementation with eMBC using WeChat and the standard MBC implementation using paper-pencil assessments at the clinic, for both implementation and clinical outcomes.
Clinical Predictors of Intravenous Ketamine Response in Treatment-Resistant Depression
Treatment Resistant DepressionMajor Depressive Disorder1 moreFor patients with treatment-resistant depression (TRD), a single low dose of intravenous (IV) ketamine can help relieve symptoms as quickly as 24 hours later. The main problem with IV ketamine for TRD is that the effect is short-lived, lasting only days to 1 or 2 weeks. Furthermore, IV ketamine is a resource-intensive treatment, and the safety of long-term, repeated use for depression is unknown. To provide this treatment in a safe and cost-effective way, Investigators must allocate it efficiently to those patients who have the greatest need and probability of benefit. Therefore, this project aims to find clinical features (signs, symptoms, and parts of a patient's history) that will help predict which patients are most likely to respond to a single dose of IV ketamine for TRD. This will help guide patient selection and triaging. Investigators will recruit 40 participants with TRD over one year, and randomize them to one of two conditions (ketamine followed by an active placebo 3-weeks later, or vice versa). With clinical data collected through detailed interviews and questionnaires, this study design will let us evaluate how well such factors predict (A) rapid response at 24-hours, and (B) sustained response at 7 and 14 days.
Low-Intensity Focused Ultrasound for Treatment-Resistant Depression
Major Depressive DisorderTreatment Resistant DepressionThe Investigators are proposing to demonstrate safety and efficacy of LIFUP for treatment resistant major depressive disorder in a ten-patient pilot study. LIFUP is an emerging treatment with the advantage of being able to target subcortical transcranial targets, which may have superior efficacy or a shorter treatment course compared to other available treatments such as transcranial magnetic stimulation. This study will investigate the effect of this stimulation on the left subgenual cingulate cortex, a highly connected node in the depression network that is correlated with clinical symptomatology.
Study to Assess the Effects of Oral NMRA-335140 Versus Placebo in Participants With Major Depressive...
Major Depressive DisorderThis is a randomized, double-blind, placebo-controlled, multicenter study to evaluate the effects of NMRA-335140 (formerly BTRX-335140) on symptoms of depression in participants with Major Depressive Disorder (MDD). The study design consists of a Screening Period (up to 28 days), and a 6-week Treatment Period (during which participants will receive either NMRA-335140 or placebo). At the completion of the 6-week Treatment Period, participants who complete the study, provide informed consent, and meet the eligibility criteria may enter an open-label extension study (NMRA-335140-501).
Repetitive Versus Deep Transcranial Magnetic Stimulation for Major Depression
Major Depressive DisorderThe goal of this randomized controlled trial is to he effectiveness of two different TMS techniques in TRD, repetitive TMS (rTMS) and deep TMS (dTMS). The main questions it aims to answer are: type of study: clinical trial participant population/health conditions : Major Depressive Disorder To assess the superiority of dTMS over rTMS in TRD To evaluate the predictive capacity of scalable candidate biomarkers Participants will be randomly allocated to one of the two intervention groups (rTMS or dTMS).
5-HTP and Creatine for Depression R33 Phase
Major Depressive DisorderThis is a three-armed clinical trial examining the effect of 5-hydroxytryptophan and creatine monohydrate as augmenting agents for the treatment of depression. Subjects will be randomized between 5-HTP 100mg BID + creatine 5g daily, 5-HTP 200mg BID + creatine 10g daily, vs double placebo, for 8 weeks. The ability of the interventions to affect biomarkers associated with depression will be assessed using brain phosphorus magnetic resonance spectroscopy, functional connectivity imaging, and plasma serotonin levels.

Potential Predictive Biological Markers of Major Depression Response to Citalopram Therapy in Anorexia...
Anorexia NervosaIn patients suffering from anorexia nervosa associated with severe major depression, serotonin reuptake inhibitor drugs have shown little efficacy in significantly reducing depressive symptoms. A possible explanation for this poor efficacy could be that people with anorexia nervosa have a deficiency in amino acids such as tryptophan, which is necessary for the production of the neurotransmitter serotonin. Therefore, tryptophan supplementation has been suggested as a means of increasing the pharmacological response to serotonin reuptake inhibitor drugs in patients with anorexia nervosa. Furthermore, malnutrition present in patients suffering from anorexia nervosa is in some cases associated with problems of intestinal absorption of nutrients, with possible implications on the pharmacokinetics of the drugs administered, including selective serotonin reuptake inhibitors (SSRIs). The present observational study aims to evaluate the correlations between the clinical response to Citalopram therapy (in different o.s. and i.v. formulations) and some nutritional, neurotransmitter and inflammatory biomarkers, in order to identify potential predictive markers of response to therapy for severe major depression in patients with anorexia nervosa. The following parameters will be evaluated in patients enrolled in all 3 observation times described above: Plasma concentration of Citalopram Serum concentration of Serotonin Plasma concentration of dopamine Serum concentration of Tryptophan Serum concentration of BDNF Hamilton scale 17 items and other clinical scales (EDI-3, SCL-90, BUT).
