Filter by:The aim of this project is to evaluate the efficacy of the influenza vaccine in individuals with major depressive disorder (MDD) as well as to elucidate the nature of the immunological abnormalities in MDD using a quasi-experimental design. Specifically, the investigators plan to induce transient, mild inflammation in medically-healthy study participants using the influenza vaccine. Initially the investigators will conduct a pilot project with up to 20 individuals in order to evaluate the time-point at which the peak inflammatory response to the vaccine occurs. Subjects will receive the seasonal influenza vaccine and provide blood samples 4 hours, 2 days, and 30 days post vaccination. Subsequent to the pilot study, both depressed and psychiatrically-healthy participants will be randomized in a parallel group, double-blind design so that they receive either influenza vaccine (seasonal vaccine) or saline (i.m). At baseline, subjects will provide a blood sample, complete a number of rating scales to measure mood and fatigue, and may complete approximately one hour of MRI scanning with or without simultaneous EEG recording. Two-days post vaccination, they will provide a second blood sample, complete more clinical ratings and may complete another identical MRI session with or without simultaneous EEG. Four weeks later, participants will be asked to return to provide a third blood sample and complete additional clinical ratings. The blood samples will be used to measure both innate and adaptive immune function and may be used to correlate the vaccine-induced immunological changes to neurophysiological changes in the brain measured by MRI and/or EEG.
The overarching goal of this study is to build the most cost-effective adaptive implementation intervention involving a site-level implementation intervention strategy: Replicating Effective Programs (REP), and the augmentation of REP using either External Facilitation or a combination of an External and Internal Facilitation to improve patient outcomes and the uptake of an evidence-based program for mood disorders (Life Goals-LG) in community settings.
One purpose of this study is to test whether adding metformin will limit some of the unwanted effects of clozapine, compared to not adding metformin. Metformin is a medication that is approved by the United States Food and Drug Administration (FDA) for the treatment of type-2 diabetes. Studies have found that people with type-2 diabetes often lose some weight when they take metformin, however the FDA has not approved metformin for weight loss, so for this study the use of metformin is investigational. This study will test whether metformin can help people with schizophrenia or schizoaffective disorders lose weight. Another purpose of this study is to test whether adding fish oil will improve the benefit of clozapine and/or limit some of the unwanted effects of clozapine, compared to not adding fish oil. Fish oil is a medication used to reduce levels of some fats (triglycerides) in blood. Some studies have found that adding fish oil reduces psychosis (voices, suspiciousness). However the FDA has not approved fish oil for reducing psychosis, so for this study the use of fish oil is investigational. This study will test whether fish oil can help people with schizophrenia or schizoaffective disorders have less psychosis. Fish oil is not an antipsychotic medication.
Observational evidence and findings from clinical trials conducted for other reasons suggest that lithium, a drug used for the treatment of bipolar disorder, and, to a lesser extent, depression, may reduce rates of suicides and suicide attempts. However, this hypothesis has not yet been adequately examined in a randomized clinical trial conducted specifically to test lithium's efficacy in preventing suicides. This clinical trial fills this gap. This study is feasible within the Department of Veterans Affairs (VA) because it is a large, integrated health system with existing programs for identifying patients at risk for suicide and delivering enhanced services. In VA, approximately 12,000 patients with depression or bipolar disorder survive a suicide attempt or related behavior each year, and 15% of them repeat within one year. Experimental treatment in this study will supplement usual care for major depression or bipolar disorder, as well as VA's standard, enhanced management for patients at high risk. The investigators will recruit 1862 study participants, from approximately 30 VA Hospitals. Participants will be patients with bipolar disorder or depression who have survived a recent episode of suicidal self-directed violence or were hospitalized specifically to prevent suicide. Randomly, half will receive lithium, and half will receive placebo. Neither the patients nor their doctors will know whether a particular person has received lithium or placebo. The treatment will be administered and the patients will be followed for one year, after which patients will go back to usual care. Recruitment will occur over 3 years. The investigators are primarily interested in whether lithium leads to increases in the time to the first repeated episode of suicidal behavior, including suicide attempts, interrupted attempts, hospitalizations specifically to prevent suicide, and deaths from suicide. In addition, this study will allow us to explore whether lithium decreases the total number of suicidal behaviors, and whether it has comparable effects on impulsive and non-impulsive behaviors. If there is an effect of lithium, the investigators will be interested in whether or not it could be attributed to improved control of the underlying mental health condition, or, alternatively, whether it represents a direct effect of suicide-related behavior.
Validation of [18F]-FES for imaging of estrogen receptors in the brain The primary objective of the study is to determine if [18F]-FES Positron Emission Tomography (PET) can be used to quantify the estrogen receptor expression in the human brain.
Major depressive disorder (MDD) affects about 5% of adolescents and is on the rise both internationally and in Norway. Further, it is also associated with increased risk for suicide. Not surprisingly, depression is the largest reason for referral to specialty mental health services for adolescents (13-17 years) in Norway. Although anti-depressants and Cognitive behavioral therapy are strong treatments and have received extensive research, the best treatments show a recovery rate of only 37 %. There is a need to develop and test alternative treatments that can stand alone or augment anti-depressant medication. Family factors play an important role in the etiology, maintenance and relapse of depression. A promising family-based treatment (Attachment based family therapy- ABFT) was imported to Norway and its feasibility tested in a pilot randomized clinical trial with 20 families. The results showed promising treatment outcomes. Although the developers of the model have refined, adapted the model to suicidal ideation and built strong technology to support dissemination, a definitive study of ABFT for adolescents with major depression has not yet been conducted. Therefore the primary aim of this study is to test if ABFT is more effective that enhanced usual care (EUC) to treat clinic-referred adolescents with major depression. The investigators will test the hypothesis that 12 weeks of ABFT therapy will produce a greater proportion of adolescents report remission from depression and symptom change than 12 weeks of enhanced clinical care (EUC). Secondary research aims are i) to test a hypothesis that parent-adolescent conflict will be more sensitive to change for adolescents receiving ABFT that adolescents receiving EUC ii) to explore patterns of change in suicidal ideation in the recruited sample in the acute-phase treatment. Central challenges to the study are i) blinding therapists/patients, which is difficult in psychotherapy trials ii) lack of a standardized control condition, and iii) selecting and training regular staff therapists to high adherence levels. However, with tighter control over these factors than is normal for a typical effectiveness trial, the investigators expect results to show what to expect under the "best of conditions" in community clinics. Benchmark derived from the study will inform how to effectively train therapists and subsequently implement the model into mainstream services.
The primary goals of this work are: a) to establish a unique collection of mood disorder patients across the life cycle, including children, adults and geriatric patients, with well-defined medical co-morbidities and medication treatment outcomes at the University Hospitals Case Medical Center Department of Psychiatry; b) to establish a collection of nuclear families, including both mothers and fathers, of children diagnosed with mood disorders; c) to perform a systematic genetic analysis of the proposed sample repository to identify genes and genetic variants contributing to inter-patient variability in clinical phenotypes and treatment responses. Our primary hypothesis is that genetic variations may underlie individual variability in disease susceptibility, clinical phenotypes and treatment safety, tolerability, and effectiveness.
Suicidal behaviour (SB) represents a major public health problem, costing life in more that one million people every year worldwide. Even if SB is considered as a consequence of social adversity and depression, these stress factors are often necessary but not sufficient to explain the occurrence of a suicidal act. A preliminary study suggests that an increased perception of psychic pain during a major depressive disorder increases the risk of suicide behaviour. The investigators aimed to investigate the relationship between social exclusion (a classic trigger of psychic pain) and SB and improve our knowledge about the physiopathology of this domain.
The purpose of this study is to help us understand how depression changes brain activity and how this relates to mood, anxiety, and cognitive functions like memory. We also hope to develop a brain imaging test that will predict either before or within two weeks of starting a medicine whether the treatment will work.
The purpose of this research study is to see how certain hormones cause changes in mood and thinking in some depressed patients and to determine the effectiveness of mifepristone in treating some forms of depression. This study is conducted in conjunction with an observational study "Clinical and Biological Characteristics of Psychotic Depression".
