The purpose of this study is to examine the effects of exercise on the symptoms of depression using serum levels of serotonin, catecholamine's, Alpha EEG asymmetry, and self-report of symptoms as markers. In an attempt to further understand the mechanisms of improved mood through exercise; this study will examine the known factors that contribute to depressed mood in a single study using serotonin and catecholamine levels via blood serum and EEG slow wave asymmetry. Such information can be useful in understanding the overall neurological components of depression and the effects of exercise on the brain in depressed individuals that would make the prescription of exercise a viable treatment option.
The specific aims of the proposed study are to: 1. Develop the innovative depression care management technology, including the speech recognition technology for automated monitoring and patient prompts over time, automatic integration of the responses into the patient registry, and evidence-based decision-support algorithms for care actions; 2. Conduct the quasi-experiment in eight Los Angeles County Department of Health Services (LAC-DHS) clinics to test the interventions; 3. Use mixed-method evaluation to assess the extent of the implementation of the interventions, the acceptance to the providers and to the patients, and the impact on adoption of depression screening and treatment management over time, utilization, and cost of healthcare services, and patient health outcomes; and 4. Conduct a cost-effectiveness analysis of the three study arms. Successful completion of the study will demonstrate which Comparative Effectiveness Research (CER) adoption strategies are successful and why, their comparative cost-effectiveness, as well as which strategies are successful under which circumstances to inform system-wide implementation of same. Hypotheses of the Proposed Study The following are the main hypotheses of the study: 1. There will be statistically significant difference in the adoption of depression care screening and management over time among the three study groups. 1.1. The adoption rate will be Technology-supported care (TC) > Supported Care (SC) > Usual Care (UC). 2. There will be statistically significant difference in the depression symptom reduction, and better functional status, and quality of life among the three study groups. 2.1. The difference between the TC and the SC will not be statistically significant, but both will be greater than the UC group. 3. There will be statistically significant difference in the diabetes care process and outcomes among the three study groups. 3.1. The difference between the TC and the SC will not be statistically significant, but both will be greater than the UC group. 4. There will also be statistically significant differences in healthcare utilization among the three study groups, with least utilization in the TC group where the greatest level of technology is applied. 5. Of the three groups compared, the TC group will be the most cost-effective approach for accelerating adoption of the CER depression care results.
Depression is common among elderly with an estimated prevalence of 5%. Due to ageing the national burden will double in the coming decade. Antidepressants as TCAs and SSRIs are effective in reducing symptoms, especially in people with severe depression. To optimize treatment efficacy and reduce side effects, the Pharmacogenetics Working Group of the Royal Dutch Pharmacists Association developed guidelines for dose-adaptation, for instance for antidepressants such as nortriptyline and venlafaxine based on their main relevant genotype (CYP2D6) accompanied by Therapeutic Drug Monitoring. Such personalized drug dosing based on pharmacogenetic information at the start of therapy can speed up the titration phase of antidepressants to establish an adequate maintenance dose. However, pharmacogenetic screening programs are expensive and evidence on effects and costs of such a program among elderly antidepressant starters from randomized controlled studies is lacking. The investigators will conduct a pragmatic randomized controlled trial to determine the effects and costs of pharmacogenetic screening information to optimize drug dosing in depressed elderly patients who start with nortriptyline or venlafaxine. Objective: The primary objective is to determine the effects of pharmacogenetic screening for CYP2D6 on the time to reach adequate blood levels as an accepted proxy for adequate treatment. Secondary objectives include adverse drug reactions and cost-effectiveness Study design: pragmatic randomized controlled intervention study
The investigators will investigate in a sham controlled staggered onset design antidepressant effects and safety of deep brain stimulation (DBS) to the superolateral branch of the main medial forebrain bundle (slMFB).
The purpose of this research study is to examine whether a one-day group workshop, integrating principles from Acceptance and Commitment Therapy with Migraine Education, will result in improvements in depressive symptoms and functioning impairment in patients with comorbid migraine and depression.
The purpose of this study is to evaluate the safety of PDC-1421 Capsule in healthy subject, find the effective adequate dose for the next stage of the study, and accumulate information of possible mechanism of its anti-depressive effect.
The investigators will evaluate effects of introducing the care manager on: 1. Patient receipt of timely diagnosis and initiation of treatment for major depression (diagnosis within 2 weeks of screening and treatment within 1 month of diagnosis); and 2. Patient continuity of care for depression across the transition of care from pregnancy to postpartum (within 4 months postpartum).
This study aims to compare the effectiveness of two telephone-based psychotherapy (Tel-PT) interventions for patients with mild to moderate depression. Both interventions consist of one personal session and weekly to bi-weekly 8-10 telephone sessions with a licensed cognitive-behavioral psychotherapist accompanied by the study of educational materials and the completion of regular monitoring questionnaires (total treatment duration: approximately 3 months). Patients are randomized into one of two conditions: Patients in the condition "Tel-PT including mail" additionally receive a motivating letter from their psychotherapist after each telephone session, while patients in the condition "Tel-PT without mail" receive no further interventions. Patients refusing to be randomized are to be assigned to the condition "Tel-PT without mail". This study takes place within a larger study evaluating a stepped care model for depression (01KQ1002B-TP7).
Understanding the neural and biological mechanisms by which reproductive hormones influence mood is critically important for public health given that postpartum depression (PPD) is the leading cause of morbidity and mortality associated with childbirth and has negative effects on infants. Using a hormone-withdrawal challenge to precipitate mood symptoms will improve our ability to identify the biological mechanisms underlying both the triggering of and susceptibility to depressive disorders in women; and will permit the prediction of those at risk for PPD and other reproductive-related mood disorders.
