Filter by:The objective of this study is to collect data to finalize the development of MEB-001 software as a medical device. The data collected in this study will be used to develop MEB-001 machine learning algorithms by training the algorithms to match the patient's demographic and clinical information, and the objective physiological signals (i.e., electroencephalogram (EEG) and electrocardiogram (ECG)) recorded during PSG with the diagnosis of cMDE performed through the MINI neuropsychiatric evaluation.
Gallbladder meridian(GB) acupoints may play an important role in the treatment of major depressive disorder (MDD). Therefore, this study is designed to focus on the traditional Chinese medicine (TCM) theory of " gallbladder dominating decision ", take the GB as the entry point, and use functional Near-Infrared Spectroscopy(fNIRS) technology to observe the effect of intradermal acupuncture on the cerebral hemodynamic indexes of the prefrontal cortex and bilateral temporal cortex of patients with MDD.
Background: Major depressive disorder (MDD) is a psychiatric condition. People with MDD have occasional bouts of depressive symptoms; these bouts are called major depressive episodes (MDEs). Researchers want to know if people having MDEs have lower levels of an enzyme called PDE4B in their brains. Objective: To find out (1) if PDE4B can be detected in a person s brain using a special scanning method and (2) if brain PDE4B levels are lower in people having an MDE. Eligibility: People aged 18-70 years with MDD. Healthy volunteers are also needed. Design: Participants will have up to 5 clinic visits. Participants will be screened. They will have a physical exam with blood tests. They will have a test of their heart function. Some participants may have a psychiatric assessment; they will answer questions about their state of mind and related topics. Participants will have magnetic resonance imaging (MRI) of the brain. They will lie on a table that slides into a metal cylinder. Participants will have a positron emission tomography (PET) scan. A needle will be used to guide a thin plastic tube (catheter) into a vein in one arm. An experimental substance called a radioactive tracer ([18F]PF-06445974) will be injected through the catheter. Participants will lie on a table that slides into a doughnut-shaped machine. The scan will last up to 4 hours with a 15-minute break. Participants blood pressure, heart rate, and breathing will be monitored before, during, and after the PET scan. A second catheter will be inserted in the artery of the wrist so blood can be drawn during the scan. Some participants may return for a second PET scan. https://nimhcontent.nimh.nih.gov/start/surveys/?s=KE88DXXPLDFHHTF8
The goal of this study is to evaluate whether rtfMRI-nf training to increase the amygdala response to positive memories may serve as a stand-alone intervention for major depressive disorder
The goal of this interventional study is to compare in logotherapy-based intervention practiced to depressed patients on depression, psychological pain and meaning of life. The main questions it aims to answer are: - Is the logotherapy-based intervention practiced in addition to the standard treatment in depression patients effective in reducing the depression levels of the patients? - Is the logotherapy-based intervention practiced in addition to the standard treatment in depression patients effective in reducing the psychological pain levels of the patients? - Is the logotherapy-based intervention practiced in addition to the standard treatment in depression patients effective in increasing the patients' level of meaning to life? Participants will be done online interview once a week for eight sessions. Researchers will compare intervention and control groups to see if logotherapy-based intervention practiced effect depression, psychological pain and meaning of life levels.
This study apply a wearable visual device (HMD)-VR-based software medical device for patients with depressive disorder for 8 weeks. The investigator would like to confirm evaluate the safety and efficacy of the wearable visual device(HMD)-VR-based software medical device effect of improving depressive disorder in patients.
Background of the study: Major depressive disorder is a severe neuropsychiatric condition that affects approximately 15% to 18% of people worldwide during their lifetime (Malhi & Mann, 2018). Selection of the optimal treatment is difficult. A certain correlation (functional / structural, vascular or a mix of both) is expected between clinical data (obtained from psychometric tests such as the HDRS and psychiatric evaluations) and MRI parameters (functional activity, structural connectivity, anatomical variations, perfusion / diffusion etc.). Objective of the study: Identification of MRI-based biomarkers to predict clinical outcome of major depressive disorder in comparison with healthy controls. Outcome is defined by level of depressive and cognitive symptomatology and related comorbidity. Study design: An independent treating physician will inform a potentially eligible patient and ask whether he/she is interested in voluntary participation in the study. If he/she is interested, the independent treating physician will refer the patient to one of the clinicians from the GGz who is also involved in the Neurotrend study for further steps such as providing the information letter / informed consent and scheduling an intake interview at least one week after receiving all necessary information. Healthy controls will be recruited through public advertisement and via the website www.neurotrend.nl. Pilot subjects will be recruited from the Eindhoven University community and via the website www.neurotrend.nl. Both groups, healthy controls and pilot subjects, will have at least one week to consider and decide on participation. One week later an intake session will take place in which the inclusion and exclusion criteria will be checked. During this session, patients can also ask questions about the study and the informed consent will be signed if the participant is willing to participate voluntarily in the study. Subsequently at the end of the intake session, a starting (baseline) date will be planned for this participant . The actual participation starts at baseline. In total, 120 depressed patients and 60 healthy controls will participate in the study. Each participant visits Kempenhaeghe twice, whereby each session, is dedicated to complete questionnaires and cognitive tests, such as memory tasks and eye tracking. In the last hour, the participant will be scanned (MRI). Two weeks before each visit, the participant has to fill in some questionnaires that have been sent to the participant. Study population: 120 patients with major depressive disorder and 60 healthy controls*. * Inclusion of up to 30 healthy "pilot" participants for technical evaluation. See above. Primary study parameters/outcome of the study: - Hamilton Depression Rating Scale (HDRS) scores - Treatment / medication usage - MRI metrics (varies per MRI modality, an example is volume per region for a T1-weighted scan and fractional anisotropy for diffusion-weighted scans). Secondary study parameters/outcome of the study (if applicable): - Scores of psychometric assessments (e.g. STAI-DY1 - anxiety score) - Scores of cognitive assessments (e.g. average response time for the eye-tracking task) Nature and extent of the burden and risks associated with participation, benefit and group relatedness (if applicable): The participant burden is low and is divided into an intake session and two research sessions. The MRI scan is non-invasive, and subjects can indicate that they want to stop the scan at any time during the scan by squeezing a type of balloon that will lie next to the subject in the case that they feel uncomfortable or for any other reason. Subjects with MRI contraindications (e.g. claustrophobia, pregnancy or implants not suitable for MRI) are already excluded in advance and will therefore not participate in the study at all. Mostly, the subjects will lie still during the scan, except for one affective task in which they will be asked to match different emotional faces for about 5 minutes.The cognitive tests will only consist of memory, reaction speed, attention, and processing speed tasks which in total, do not last more than 30 minutes. The risks of the MRI scanner (CE-marked) are minimal.
The Reach Out, Stand Strong, Essentials for New Mothers (ROSE) program is an evidence-based intervention that prevents half of cases of postpartum depression and was one of two interventions recommended by the US Preventive Services Task Force in 2019. All effectiveness trials of ROSE and of the other recommended PPD prevention intervention included only low-income women a single risk factor that doubles incidence of PPD. Thus, the existing evidence base for PPD prevention consists primarily of women at increased risk for PPD. Based on data from the PIs' current implementation study of ROSE, many healthcare and community agencies in this implementation trial (78%) find it is more feasible for them to provide or offer ROSE to every woman as part of their standard workflow, than it is to create a screening and referral process for at risk women. In addition to being more feasible for agencies, universal prevention may also be advantageous because the cost of a screening false negative (resulting in a preventable case of PPD; $32,000) far exceeds the cost of ROSE delivery ($50-$300/woman). Effectiveness of ROSE among low-income women at risk for PPD is known (ROSE prevents ~50% of PPD cases). To inform a recommendation about using ROSE as universal vs. selective or indicated prevention, we need to determine the effectiveness of ROSE among general populations of women, including women screening negative for PPD risk. Thus, this project will assess ROSE effectiveness across PPD risk levels and across prevention approaches in a sample of 2,320 women from a large regional health system (based in Detroit, MI). Each proposed aim gathers a piece of information missing that is needed to guide decision-making about ROSE as universal prevention. We will assess ROSE as universal, selective, and indicated prevention in terms of: (1) ROSE effectiveness relative to a control for each prevention approach in preventing PPD and improving functioning; (2) cost outcome, (3) equity and (4) scalability of each prevention approach; and (5) mechanisms of ROSE effects across PPD risk levels. We will integrate results to advise about ROSE as universal prevention. This definitive PPD prevention trial will show how best to get an evidence-based program to those who need it in settings where they receive perinatal care by addressing a pragmatic and novel question (should ROSE be universal prevention?) and by examining equity and cost-outcome of universal vs. other prevention approaches.
In this study, the investigators aimed to observe the effects of medium cut-off dialysis filters and high-flux dialysis filters on malnutrition inflammation score, uremic itching, restless leg syndrome, anemia, and ESA treatment, which are prominent complications in hemodialysis, and routine follow-up parameters.
Postpartum 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.
