Peripheral Neuroimmune Mechanisms of Hyperthermia
HyperthermiaMajor Depressive Disorder1 moreThe goal of this study is to examine how whole-body hyperthermia affects the thermoinflammatory profile, which includes the combined immune and heat shock response, in patients with depression and whether these changes correlate with decreased depression in individuals with Major Depressive Disorder.
Intensive TMS for Bipolar Depression
Bipolar DepressionTreatment Resistant DepressionThe research study is being conducted to test whether using high dose spaced theta-burst rTMS (a form of transcranial magnetic stimulation) produces a significant reduction in depressive symptoms compared with sham. This project will recruit patients aged 18-70 with symptoms of bipolar depression who have failed (or not shown signs of improvement) after at least two prior treatments.
Going to Altitude With Anxious-depressive Symptoms
HypoxiaMental DisorderIntroduction: Currently, there is a lack of international guidelines or clinical recommendations for individuals with mental illnesses (i.e., bipolar disorder, posttraumatic stress disorder) going on high altitude sojourns. However, these guidelines would be important considering that mental illnesses are among the most common disorders worldwide and millions of people are hiking at high altitudes in the Alps, being granted easy access up to 3800m by cable cars. Before conceptualizing these guidelines, it seems necessary to study the physiological and psychological effects of ambient pressure changes leading to oxygen deficiency (hypoxia) in individuals with mental illnesses when being exposed to hypoxic conditions. The investigators hypothesize a shift towards negative affective responses and state anxiety as well as increased levels of neurotransmitter precursor amino acids (PHE/TYR and KYN/TRP) in individuals with mental illnesses when being exposed to hypoxic conditions. Methods and Analysis: The investigators plan to perform a double-blind randomized controlled trial in a safe laboratory environment by using a normobaric hypoxic chamber. Participants suffering from depression and anxiety symptoms will be included as well as age and sex-matched healthy controls. They will attend a six-hour exposure equivalent to 3800m of altitude as well as a six-hour exposure to sham hypoxic conditions. Recruited participants will be screened by the Beck Anxiety and Depression Inventory, the Symptom Checklist (SCL-90) as well as an interview assessment. Affective responses in state anxiety will be assessed before, and during each hour of exposure by using the Feeling Scale (FS), Felt Arousal Scale (FAS), Positive and Negative Affect Schedule (PANAS), State-Anxiety Inventory (STAI) and subjective mental stress levels (Visual Analogue Scale; VAS). Physiological parameters will be assessed by venous blood sampling, pulse oximetry and oxidative stress level measurement before entering the chamber, after three and six hours of exposure. Additionally, symptoms of acute mountain sickness will be assessed by the Lake Louise Score before, after three and six hours of exposure. Follow-up measurements are planned one and seven days after the chamber visit, consisting of venous blood sampling, the Beck Anxiety and Depression Inventory. A series of univariate analyses of covariance (ANCOVA) for repeated measures will be used to test the three-way (i.e. "group × condition × time") and two-way ("group × condition" and "group × time") interactions. Analyses will be adjusted for possible confounding, by adding age, sex, smoking, prior AMS, and medication status in the models as covariates. Ethics and dissemination: Ethical approval has been obtained from the ethics committee of the Medical University of Innsbruck (1250/2021).

Reducing Depressive Symptoms Among Rural African Americans
Depressive SymptomsRural African Americans are disproportionately impacted by social stressors that place them at risk for experiencing elevated depressive symptoms. This project will test the effectiveness of a culturally adapted behavioral activation intervention (REJOICE) for use within rural African American churches. Further, this project will gather data on strategies necessary to promote the successful implementation of this intervention within rural African American churches.

Tractography Guided Subcallosal Cingulate Deep Brain Stimulation for Treatment Resistant Depression...
Treatment Resistant DepressionUndergoing Deep Brain Stimulation (DBS) SurgeryTreatment resistant depression remains a major problem for individuals and society. Surgical procedures may provide relief for some of these patients. The most frequently considered surgical approach is deep brain stimulation (DBS) of a part of the brain called the subcallosal cingulate region. However, the effectiveness and safety is not well established. The investigators will use a novel approach using advanced imaging technique (magnetic resonance tractography) to evaluate the feasibility and safety of this surgical approach. An innovative method for the definition of DBS target will be applied that redefines the concept of targeting as one of targeting a symptomatic network rather than a structural brain region using subject-based brain anatomy to define the target location. The correlation between imaging findings at baseline with the mood score changes at different time points of the study will be investigated.
Slow Wave Induction by Propofol to Eliminate Depression (SWIPED)

Supportive Text Messaging Versus Supportive E-mail Messaging for Patients With Major Depressive...
Major Depressive DisorderBackground: In 2012, over 3.2 million Canadians over 15 (11.3%) years reported symptoms of major depressive disorder (MDD), and barriers such as lack of readily available care system, stigma and affordability of health care services were reported by millions of Canadians who expressed they had unmet or partially met mental health care needs. There is the need to develop innovative psychological interventions which are not human resource intensive, are easily accessible, cost-effective, are geographic location independent, scalable, and can be offered to thousands of people simultaneously. Supportive text messaging has been proven in clinical trials to be effective in alleviating depression symptoms but are limited in their ability support those without active cell phones. Objective: The objective of this study is to evaluate the feasibility, comparative effectiveness and user satisfaction with daily supportive e-mail messaging as an intervention to treat patients with MDD when compared to daily supportive text messaging. Method: In this innovative two-arm randomized non-inferiority pilot trial, patients with MDD receiving usual care would be randomized to receive either daily supportive email messaging or daily supportive text messaging of the same content for six months. The Patient Health Questionnaire (PHQ)-9 scale will be utilized to record depression symptom scores, the Generalized Anxiety Disorder (GAD)-7 scale would be used to record the anxiety symptoms and quality of life will be measured using the WHO (Five) Well-Being Index (WHO-5) at baseline, 6, 12 and 24 weeks. Primary outcomes would be the mean difference in change scores on the PHQ-9 and WHO-5 scales from baseline to 6, 12 and 24 weeks for the two study arms. Secondary outcomes include changed scores on the GAD7 scale from baseline to 6, 12 and 24 weeks for the two study arms, the dropout rates and the satisfaction rates at 12 and 24 weeks for participants in the two treatment arms. All outcome measures would be analyzed using descriptive and inferential statistics. Qualitative data will be analyzed using thematic analysis aided by NVIVO software. Results: We expect the study results to be available within 18 months of study commencement. Conclusion: The results of this study will shed light on the feasibility, acceptability and effectiveness of using automated email supportive message interventions in the management of patients with MDD.
Fitness for Brain Optimization for Late-Life Depression
Depression in Old AgeCognitive impairment and brain abnormalities are common and persist after depression remission in those with Late Life Depression (LLD), compounding dementia risk in both individuals with acute and remitted LLD (rLLD). In this study, investigators will examine systemic neural and cognitive benefits of aerobic exercise training in older adults with remitted LLD. This will generate preliminary data regarding neural targets of aerobic exercise training that may translate to cognitive benefits in those with rLLD, a population who remains at high risk for dementia despite successful treatment of depression.
