Post-traumatic Stress Injuries Among Paramedics and Emergency Dispatchers

As part of their work, emergency first responders, such as paramedics and emergency medical dispatchers are exposed daily to traumatic events. These traumatic events can have many impacts on mental health, such as acute stress disorder and post-traumatic stress disorder. Research has shown that intervening early after exposure to a traumatic event helps to identify people at risk and to prevent post-traumatic stress disorder. The Psychological First Aid approach originally developed for mass traumas, is an intervention advocated by international experts today following a traumatic event. However, this approach is still very little studied, especially when it is part of an organization of emergency first responders. It therefore still lacks scientific validity. The main objective of this research will be to assess whether the Psychological First Aid program provided by peer-support workers helps to reduce the initial distress caused by traumatic events and to foster short- and long-term adaptive functioning and coping.

Citalopram and Self Emotional Processing

This study is investigating the effect of an acute dose of citalopram on emotional processing about the self. Using a parallel-group double-blind design, participants will be randomised to receive either an acute dose of citalopram or placebo. Participants will then complete a number of widely used computer-based cognitive tasks measuring emotional processing biases towards the self. This study has also been registered on OSF: https://osf.io/nhjvs/?view_only=b39c49bddfd543b99b627dc992e49b45

Citalopram and Stress Reactivity

This study is investigating whether acute administration of citalopram is associated with a decrease in stress reactivity in healthy volunteers, compared to placebo administration. Using a parallel-group double-blind design, participants will be randomised to receive either an acute dose of citalopram or placebo. All participants will have come in for a screening visit. On the day of the research visit (following drug administration) participants will have completed a number of widely used computer-based cognitive tasks measuring emotional processing biases. They will then complete the Oxford Cognition Stress Task, a web-based acute stress induction paradigm, which is designed to induce mild transient increases in stress and arousal. Identifying early changes in stress reactivity following antidepressant treatment will increase the investigator's knowledge of how antidepressants operate, and provide putative targets to identify early response to antidepressants.

A Clinical Trial of Fluvoxamine for Melancholia

This study aims at investigating the special effectiveness of antidepressant effect of Fluvoxamine for endogenous depression. The investigators also aim to assess the effect of Fluvoxamine on the multimodal magnetic resonance imaging(MRI), blood cytokines, feces bacteria flora and neuropsychological performance in depression patients with melancholic features. The investigators further aim to identify the predictors of Fluvoxamine's antidepressant effeect using the above techniques.

Targeting Adolescent Depressive Symptoms Via Brief, Web-Based Interventions

Major depression (MD) in youth is a serious psychiatric illness with extensive morbidity and mortality. The American Academy of Pediatrics recently released practice guidelines promoting primary care (PC)-based youth MD screening; however, even when diagnosed by PC providers, <50% of youth with MD access treatment. Thus, a need exists for interventions that are feasible for youths and parents to access and complete-and that may strengthen parents' likelihood of pursuing longer-term services. Single-session interventions (SSIs) may help forward these goals. SSIs include elements of comprehensive treatments, but their brevity makes them easier to disseminate at scale. Meta-analytic evidence suggests SSIs can reduce youth psychopathology, including self-administered (e.g., online) SSIs. One computer-based SSI, teaching growth mindset (GM; viewing personal traits as malleable), has reduced adolescent depressive symptoms in multiple RCTs. A second computer-based SSI was recently developed to reduce youth depressive symptoms via targeting reductions in self-hate-a symptom identified as important for the maintenance of other depressive symptoms in teenagers. This study will test whether either the growth mindset SSI (GM-SSI), the self-kindness SSI (SK-SSI), or both SSIs reduce symptoms of depression in adolescents, relative to an active "supportive therapy" SSI, which teaches adolescents to share their emotions with trusted others. Youths participating in existing research through the Healthy Brain Network (N=501) will receive either the growth mindset SSI (GM-SSI), the self-kindness SSI (SK-SSI), or the supportive therapy SSI (ST-SSI). The investigators will examine whether the GM-SSI and/or the SK-SSI, versus the ST-SSI will reduce youth depressive symptoms across three months. Results may identify two novel, potent, and brief interventions for adolescent depressive symptoms.

Intermittent Theta Burst for the Treatment of Alcohol Use Disorders in Veterans

The purpose of this study is to evaluate the efficacy of intermittent theta burst repetitive transcranial magnetic stimulation (iTBS) as a treatment for Veterans with an alcohol use disorder (AUD) to decrease the exceedingly high rate of relapse associated with this condition. iTBS has demonstrated equivalent efficacy and safety to repetitive transcranial magnetic stimulation employing 10Hz stimulation protocols in treatment of depressive disorders. The advantage of iTBS is that it can be delivered in approximately 5 minutes where conventional 10Hz repetitive transcranial magnetic stimulation (rTMS) protocols are typically 20-25 minutes. It is hypothesized that Veterans with AUD who receive active iTBS applied to the left dorsolateral prefrontal cortex (DLPFC), compared to controls (i.e., Veterans with AUD who receive sham iTBS), will show significant decreases alcohol craving, depressive symptomatology and cigarette consumptions, as well as improved neurocognition, a longer period of abstinence, and a lower overall rate of relapse over 6 months following standard psychosocial treatment for AUD at VA substance treatment clinics. In exploratory analyses, it is also predicted that magnetic resonance measures of left DLPFC glutamate concentration, volume of anterior frontal cortical brain regions, and performance on fMRI tasks interrogating the function of the salience/reward circuits will serve as biomarkers of iTBS treatment response. The goal of this proposal is to implement treatment that effectively promotes sustained abstinence in Veterans with AUD, given long-term abstinence is related to optimal neurobiological, neuropsychological and psychosocial recovery and functioning.

Follow-up Study With Clinical Vitamin D Supplementation Trial on Patients With Depression (DepFuD)

Depression affects 350 million people worldwide. In the light of the global disease burden statistics, the efficacy of current treatments for depression appears insufficient. Thus, research on novel treatment interventions and predictors for good treatment response are warranted. Earlier prospective follow-up studies and intervention studies suggest that several bio-psychosocial factors, including high serum concentrations of vitamin D, are related to better treatment outcomes. In this follow-up study with randomized clinical vitamin D supplementation trial on patients with depression, the investigators aim to clarify how a six-month intervention with vitamin D supplementation affects treatment response, recovery, and the biological pathways related to depression. This aims to finding potential sub-groups getting benefits from vitamin D supplementation. In addition, the investigators want to investigate and characterize factors related to recovery from depression and working ability in depression patients in the long-term. The investigators are especially interested in the bio-psychosocial factors and the aims include examining both the individual's positive resources. The trial will start with a six-month double-blinded randomized controlled trial with vitamin D supplementation. The aim is to recruit altogether 3028 patients with non-psychotic, unipolar depression, aged 18-65 years, who are referred to the recruitment sites for treatment for depression. The participants will be randomized to low (10 µg/day) or high (100 µg/day) vitamin D supplementation group. Clinically necessary antidepressant treatments will continue during the intervention as needed. After six months of intervention, the participants will be followed up at 18 months and at 5 years. Several measurements will be conducted during the intervention and follow-up period. Participants will fill a variety of clinical questionnaires and questionnaires with background information. All participants give blood samples for biomarker analyses at time points 3, 6, 18 months and 5 years. Clinical interviews of mental disorders (e.g. SCID) and anthropometric measurements (e.g. weight, height, blood pressure) will be carried out.

Does Antidepressant Use Blunt Adaptations to Exercise?

Nearly one out of ten US adults over the age of 18 currently takes antidepressant medication, which can also treat other conditions such as anxiety. Combining pharmaceutical treatment with exercise may yield even greater benefits than using drugs alone, and this is commonly prescribed for depression. However, little is known about the drug-exercise interactions and their influence on metabolic health. A common side effect of antidepressant use is weight gain, particularly abdominal (visceral) fat, which is highly detrimental to overall health. Exercise is a well-known counter to abdominal fat accumulation. The aim of the proposed study is to compare the efficacy of 6 weeks of exercise training to reduce abdominal fat in healthy overweight/obese adults either taking or not taking antidepressant medication. Twenty-four inactive overweight/obese, but otherwise healthy, adults will complete 6 weeks of an exercise training intervention consisting of three days of aerobic exercise training per week. Participants will either not be taking antidepressant medication or will have been on their medication for at least 1 year. The primary outcome will be abdominal fat determined by waist circumference and dual x-ray absorptiometry, which is considered one of the optimal methods for assessment of abdominal fat.

Light Therapy on Major Depression Disorder

Background: Major depression disorder is a common psychological disease. It is the second-ranked cause of disability worldwide. The pathophysiology is not yet understood. The main theory is monoaminergic theory based on the effect of monoaminergic drugs. Current treatment includes psychotherapy, medication and electroconvulsive therapy. The onset of action for antidepressant is often slow, therefore strategies to improve the outcome are important. Bright light therapy has been found to be effective in reducing the severity of depression not only in seasonal affective disorder but also in other affective disorder. Previous meta-analyses of light therapy for non-seasonal major depression, however, has yielded conflicting evidence for efficacy. Purpose: To investigate possible imaging biomarkers of major depression disorder To evaluate the effect of light therapy on depression Materials and Methods: This prospective study will recruit 100 patients, randomized into 2 study groups: (1) antidepressant plus treatment light, and (2) antidepressant plus placebo light. All patients will accept a thorough psychological evaluation (including Hamilton Depression Rating Scale, Montgomery-Asberg Depression Rating Scale, Clinical Global Impression-Severity and Patient Health Questionnaire-9 items) at baseline and at the 1st, 2nd, 4th, 8th week during the 8-week experiment intervention, by a blind assessor. Mini-International Neuropsychiatric Interview (MINI) and Morningness- Eveningness Questionnaire-Self-Assessment Version (MEQ-SA) were only evaluated at baseline. Adverse events were evaluated at baseline, 2nd,4th,8th weeks. MRI study will be arranged at baseline and in 4-week experiment. Predicted Results and Influence: To evaluate the additional effect of the treatment light on depression disorder To compare the difference of functional magnetic resonance imaging(fMRI), structural MRI among the two groups and between the patients with and without treatment effect in order to detect imaging biomarkers.
