How the Brain Encodes Beliefs: A Functional Magnetic Resonance Imaging Study of the Belief Updating in Treatment Resistant Depression.
Major depressive disorder (MDD) is characterized by a cognitive triad of negative beliefs about oneself, the future and the world. For example, depressed patients hold persistently negative expectations about the future, despite contradictory evidence, and these strong negative beliefs are thought to play an important role in the maintenance of depressive symptoms and potentially in treatment resistance. Indeed, one out of three patients with major depressive disorder does not respond to conventional, monoaminergic treatments, which has led to the concept of treatment resistant depression (TRD). It is unknown how the brain encodes the strong negative beliefs that are insensitive to positive disconfirming information in TRD patients, and how these neural underpinnings of maladaptive belief updating are altered by antidepressant treatment. The principal objective of this study is to gain insight into the brain mechanisms of belief updating about the future in TRD patients before and after starting ketamine treatment. The results of this study are expected to provide a better understanding of the neurocognitive mechanisms of belief-updating in depressed patients, and how these mechanisms contribute to clinical improvement following ketamine antidepressant treatment.

The Predictive Effect of Soluble Epoxide Hydrolase (SEH) on Depression Treatment, Cognition and Suicide Improvement
Depression 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.

Is Brain Insulin Resistance a Feature of the Biology of Depression: A Pilot Multi-modality Neuroimaging Study in Adolescents
This study will examine if brain insulin resistance is a feature of depression in humans using magnetic resonance imaging (MRI) measures sensitive to brain insulin action. This study will examine adolescents, as depression onset commonly occurs during this age, and the impacts of cumulative medication exposure and other lifestyle-related confounds are also lower in this age group, improving our ability to understand the underlying biology.

The Comorbidity of Depression and Cardiovascular Disease in Midlife Women: Investigating Novel Biological Pathways of Risk
Depression is a known risk factor for cardiovascular disease (CVD), and this comorbidity contributes significantly to the morbidity and mortality of women. The menopausal transition or perimenopause is a period of vulnerability for both depression and CVD, making it a key time to study this critical public health issue. This research will preliminarily explore whether disruption in two novel stress pathways 1) the renin-angiotensin-aldosterone system (RAAS) and autonomic nervous system (ANS) and their relationship may underlie the link between these illnesses. Findings will provide important insight into potential mechanisms by which depression during perimenopause may increase risk for CVD in midlife women, which will inform potential risk reduction and treatment strategies that can improve health outcomes in this population.

Repetitive Transcranial Magnetic Stimulation With and Without Text4Support for the Treatment of Resistant Depression: Patient-centered Multicentral Randomized Controlled Pilot Trial. Protocol.
This study is a multicenter prospective, parallel design, two-arm, rater-blinded randomized controlled pilot trial. Participants will be randomly assigned to one of two treatment conditions. In the first condition, treatment consists of rTMS sessions combined with Text4Support. The second condition is made up of the treatment as usual (rTMS sessions alone). The recruitment process is scheduled to last 12 months. It will involve active treatment for six weeks and follow-up period observation periods of 1,3, and 6 months for participants in both arms of the study. Participants will be recruited from four different centers for this project. Two centers (the Addiction and Mental Health clinic and the Alberta day hospital) will be from the large, sociodemographic diverse city of Edmonton in Alberta Western Canada. The remaining two centers will be in Halifax and Annapolis Valley in Nova Scotia, Canada.

Double-blind Randomized Placebo Controlled Study on the Effect of Enoxolone ( 11-beta Hydroxysteroid-dehydrogenase Type 2 Inhibitor) on the RAAS, Autonomic and Imaging Biomarkers and the Outcome of Depression
Many different forms of depression exist. It is difficult to predict to what treatment a given patient with depression responds. Studies demonstrate that biomarkers can help to distinguish different forms of depression. Simple markers, like aldosterone/cortisol in body fluids, blood pressure and inflammation markers , have been identified as predictors of therapy resistance in depression. Enoxolone is a molecule derived from the licorice plant and has demonstrated an effect on these biomarkers, which may imply an improved response. The current randomized placebo controlled study is assessing whether the presence of markers of therapy resistance can predict a preferential effect of enoxolone vs. placebo on clinical outcome. Secondarily, it is tested whether these markers change differentially in the treatment groups. Finally, the relationship between the change of the markers and clinical change will be assessed.

Effects of Insertion of Diaphragmatic Breathing Exercises, Cardiorespiratory and Strength Exercises, and Cooperative Sports Activities During Physical Education Classes on Anxiety and Depression Symptoms in Adolescents
The main objective of this project will be to verify if the insertion of diaphragmatic, cardiorespiratory and strength breathing exercises and cooperative sports activities in Physical Education classes, during a period of 12 weeks, may be able to modify the scores of symptoms of anxiety and depression in adolescent students. As secondary objectives, this project will seek to verify which of the interventions will provide the greatest reductions in students' anxiety and depression symptoms, as well as analyze their effects on other health indicators, also verifying if a greater volume of sessions can provide additional benefits to mental health. when compared to a smaller volume. This is an experimental study, of the randomized clinical trial (RCT) type. The target population will be adolescent students (14 to 19 years old) from the Federal Institute Sul-rio-grandense (IFSul) on the Bagé and Pelotas campuses. A total of 16 classes will compose the sample. The classes that have the Physical Education (PE) curriculum component in their schedule will be listed and randomized in relation to the comparator group (CG) and to the three different intervention protocols: diaphragmatic breathing exercises (intervention group 1 or GI-1), physical exercises cardiorespiratory and strength activities (intervention group 2 or GI-2) and cooperative sports activities (intervention group 3 or GI-3). The application of these interventions will occur during PE classes, twice a week at Campus Bagé and three times a week at Campus Pelotas. Interventions will last 15 minutes in groups GI-1 and GI-2, and 20 minutes in GI-3. Before the start of the intervention, baseline assessments will be carried out, consisting of primary outcomes (symptoms of anxiety and depression) and secondary outcomes (self-concept, quality of life, sleep indicators, self-perception of physical fitness, cognitive failures, strength and cardiorespiratory fitness). The groups will be compared regarding the characteristics collected at baseline and after the 12th week of intervention. The Generalized Estimating Equations (GEE) and the post-hoc Bonferroni test will be used to compare the moments (pre and post-intervention) between the groups and to identify the group*moment interaction. Analyzes will be performed by protocol and by intention to treat. The significance coefficient adopted will be p<0.05.
