Studies of Brain Function and Course of Illness in Pediatric Bipolar Disorder

This study seeks to learn more about the symptoms of severe mood dysregulation in children and adolescents ages 7-17. Children and adolescents with severe mood dysregulation (SMD) display chronic anger, sadness, or irritability, as well as hyperarousal (such as insomnia, distractibility, hyperactivity) and extreme responses to frustration (such as frequent, severe temper tantrums). Researchers will describe the moods and behaviors of children with these symptoms and use specialized testing and brain imaging to learn about the brain changes associated with this disorder.

Study of Premenstrual Syndrome and Premenstrual Dysphoria

The purpose of this study is to identify and describe the symptoms of premenstrual syndrome (PMS). Women who experience PMS symptoms will complete clinical interviews, self-rating scales, and evaluations of mood and endocrine function. A subgroup of women with severe PMS (Premenstrual Dysphoric Disorder or PMDD) will be offered additional research studies that focus on: 1) identifying the endocrine changes that may be responsible for changes in mood and behavior during the premenstrual period, 2) evaluating treatments for PMS symptoms, and/or 3) identifying genetic factors in women with and without PMS. Women with recurrent brief depression will also be recruited to serve as a comparison group.

Perimenopause-Related Mood and Behavioral Disorders

The purpose of this study is to investigate mood and behavior changes in the time period surrounding and including menopause. This is an observational study; volunteers who participate will not receive any new or experimental therapies. Controversy exists regarding the relationship between estrogen and progesterone (gonadal steroid) changes and midlife-onset depression. This study will examine the role of gonadal steroids in perimenopausal mood and behavioral disorders. Perimenopausal women with depression symptoms and a control group of healthy perimenopausal volunteers will be compared to identify correlates of the occurrence of depression. Participants with depressive symptoms may also participate in companion studies that will test the antidepressant efficacy of phytoestrogens and selective estrogen receptor modulators (SERMS). A group of younger pre-perimenopausal women with normal menstrual cycle functioning will be followed through menopause in an effort to confirm the association of depression onset with changes in reproductive endocrine functioning.

Outpatient Nurse Monitoring Under the Prevention of Recurrent Suicidal

To evaluate the impact of a specific nursing management (personalized and close, through consultation at the hospital, at home or by phone) monitoring in post-hospitalization, the suicide attempt of recurrence and suicidal crisis, in the year following a suicide attempt in patients suffering from a mood disorder (unipolar or bipolar) or reactive depression.

Effects of Postbiotics on Mood Disorders in Korean Adults

The Canadian Depression Research and Intervention Network (CDRIN) Maritimes Registry

While effective interventions for depression exist, their success rates are unsatisfactory and their provision is haphazard. The Canadian Depression Research and Intervention Network (CDRIN) Maritimes Depression Hub will improve the delivery of care and the quality of outcomes for youths, adults and seniors with depression across the Maritimes. The investigators will establish an integrated system of assessment, treatment, research and education related to depression with the active involvement of those with lived experience. The establishment of a patient registry is a key step that will facilitate evaluation and reform of current services, integration of patient choice and community resources into treatment programs, monitoring long-term outcomes, and development of more effective treatment approaches through research. The registry will facilitate research that will include validation of new diagnostic and outcome measurement tools, low-cost clinical trials and collaborative projects with national and international partners. Educational programs will involve training the next generation of researchers, those with lived experience, clinicians, and health system managers in critical appraisal and will facilitate their involvement in research. The registry, the proposed systematic measurement of outcomes and the broad dissemination of information and skills will improve the quality of research and of care as well as the experience of patients and their families. The need for a registry: It is increasingly recognized that major advances in the treatment of mental disorders will require large scale clinical research. Recently demonstrated ways of completing large-scale research with finite resources include the routine use of electronic health records (EHR), data linkage and randomized registry trial. Use of EHR is the most efficient way of rapidly obtaining large amounts of information. However, EHR cannot completely exclude confounding by indication and other unmeasured variables. Therefore, tests of treatment effects require experimental designs that cannot be replaced by routine health records data. The gold standard for testing the effects of treatment in an unbiased way is the randomized controlled trial (RCT), where measured and unmeasured confounders are balanced through the randomization process and any remaining confounding is due to chance alone. RCTs are valued as the highest level of evidence, but are costly and take significant time to be completed, partly because of the need to screen a large group of individuals to identify eligible participants. The most efficient unbiased test of interventions, new treatment modalities and novel ways of treatment delivery is a method that combines EHR use with the randomized controlled trial (RCT) methodology: the randomized registry trial (RRT). The RRT takes advantage of a registry of individuals with available information to identify a large number of individuals suitable for an RCT. The RRT approach is efficient especially if the same information (e.g. diagnosis and treatment history) is used repeatedly for different purposes. The same information can be used for clinical purposes, service improvement and multiple research projects. RRT will allow obtaining answers about the efficacy of new treatments and management strategies significantly faster and at a much lower cost than traditional RCTs. Therefore, the investigators propose to establish a registry that has the capacity to conduct RRTs. The proposed registry will be integrated with similar efforts across Canada. Jointly, this collaborative network of registries will facilitate fast and economical testing of new treatments, which is urgently needed to advance the therapeutic options for people with depression and related conditions.
