We are conducting an eight week longitudinal study to learn if blood levels of certain naturally occurring compounds and genetic markers differ between patients with depression and healthy adults who are not depressed, and if any such differences relate to memory performance, mood, and neurobiology. We are also interested in how the gut microbiome is affected by antidepressant treatment. We will do this by comparing the unmedicated depressed patients with matched healthy controls at baseline and then following the depressed patients over the course of eight weeks of standardized antidepressant treatment to gauge which baseline abnormalities normalize over the course of treatment.

Patients who undergo cardiothoracic surgery often experience pain and anxiety around the time of surgery. Currently, treatments for pain and anxiety around the time of surgery include opioids and benzodiazepines, which can have severe side effects and can be ineffective. Interventions combining virtual reality with olfactory stimuli are a promising alternative to opioids and benzodiazepines in the treatment of pain and anxiety around the time of surgery. The aim of this study is to evaluate the feasibility of a virtual reality and olfactory stimuli multimodal intervention in patients undergoing cardiothoracic surgery. In addition, the investigators will evaluate the preliminary effects of the VR/OS intervention on patient pain and anxiety before and after cardiothoracic surgery. Patients who meet study inclusion criteria and are undergoing cardiothoracic surgery may participate in this study. Patients have an equal being assigned to undergo the virtual reality and olfactory stimuli intervention or continue getting usual medical care with their doctor. If the patient is assigned to receive the virtual reality and olfactory stimuli intervention, the first therapy session will take place approximately two to four weeks before surgery. This will involve wearing a virtual reality headset and scented necklace for approximately 10 minutes. The second session will occur 90 minutes before the surgery. Additionally, for each day the patient recovers in the hospital after surgery, the patient will receive one session in the afternoon. During the patient's in-hospital recovery at night, they will receive lavender scented therapy.

Depression and anxiety disorders rank in the top ten causes of years lived with disability. Less than 50% of patients experiencing long-lasting improvements to current gold-standard treatments. Two gold-standard behavioral interventions include behavioral activation, focused on enhancing approach behavior towards meaningful activities, and exposure-based therapy, focused on decreasing avoidance and challenging negative expectations. While these interventions have divergent treatment targets, there is little knowledge to inform which strategies should be used in the frequent case of comorbid anxiety and depression. Approach-avoidance decision-making paradigms focus on assessing responses when faced with potential rewards and threats, tapping into processes important for both anxiety and depression as well as behavioral activation and exposure-based therapy. For this study, investigators will recruit individuals reporting both anxiety and depression symptoms and randomize them to one of three different interventions: (1) behavioral activation, (2) exposure-based therapy, and a non-specific therapy approach (3) supportive therapy. Participants will complete clinical, self-report, behavioral, and functional magnetic resonance imaging (fMRI) assessments before and after therapy. Investigators will use a computational approach to model factors that may influence one's behavior during approach-avoidance decision-making, including drives to avoid threat versus approach reward and confidence versus uncertainty in one's decisions. This project will accomplish the following aims (1) Determine how changes in brain and behavior responses during approach-avoidance conflict relate to changes in mental health symptoms with the different therapy approaches, (2) Determine the degree to which baseline brain and behavior responses during approach-avoidance conflict predict response to the different therapy approaches, above and beyond the influence of demographics and baseline symptom severity. In addition, by including peripheral blood draws and measures of grace matter volume, the project will also accomplish the following aims: (1) Determine whether kynrenine metabolites measures peripherally may be beneficial as a biomarker of treatment response and (2) determine whether there is an association between change in kynurenine metabolites and changes in gray matter volume with treatment. Results will enhance understanding of how different psychotherapy approaches (behavioral activation, exposure-based therapy) may impact brain responses and decisions when faces with potential reward versus threat and approach versus avoidance drives. In addition, results will have important implications concerning the potential for a more personalized approach to psychotherapy, enhancing knowledge of which types of therapy strategies may be most beneficial for which individuals.

The investigators are conducting a randomized controlled trial to evaluate the antidepressant effects of nitrous oxide in people with Major Depressive Disorder (MDD). MDD is a global medical condition that causes significant health and economic burden. Recent studies have shown that a single dose of ketamine, an NMDA-antagonist, has fast and long lasting anti-depressant effect. Nitrous oxide, another NMDA-antagonist, is widely used for anesthesia and analgesia, safer to administer and has fewer side effects than ketamine. A randomized controlled crossover feasibility study showed significant reduction in depressive symptoms at 2 and 24 hours after a single 1-hour treatment session of inhaled nitrous oxide compared with placebo. Nitrous oxide is inexpensive and can be safely administered by any trained clinician. If found to be efficacious, it could be used to provide rapid anti-depressant effect whilst the benefit of traditional anti-depressants has its delayed effect. Another potential application could be in acutely suicidal patients. This investigated-initiated phase 2b trial will enable confirmation and extension of the findings from the feasibility study, and identify the optimal dose and regimen in a broader population of those with MDD. Participants will be randomized to receive a weekly 1-hour inhalational sessions of either nitrous oxide or placebo (oxygen-air mixture) for 4 weeks, and the nitrous group will be further randomly assigned to a dose of 50% nitrous oxide or 25% nitrous oxide. Depression severity will be assessed by a blinded observer pre-treatment and at weekly intervals during and for 4 weeks after treatment using the Hamilton Depression Rating Scale.

Almost 18 million US adults have alcohol use disorders (AUD), with one third of these individuals also diagnosed with anxiety disorders (AXD). The coexistence of AUD and AXD imposes a high burden via healthcare costs and lost productivity. To date, existing treatment approaches for addressing AUD/AXD comorbidity have been only modestly effective and there is a lack of adequate research to guide treatment decisions. The Unified Protocol (UP) is a transdiagnostic, cognitive-behavioral therapy that has shown efficacy in treating emotional disorders. The efficacy of the UP to facilitate abstinence from alcohol consumption in individuals with comorbid AUD/AXD has also been examined, with results from this study indicating a reduction from baseline in drinks consumed per day. However, further evaluation of the UP for managing AUD/AXD is warranted. In this clinical trial, the investigators will further assess the UP's effectiveness in reducing alcohol consumption in patients with comorbid AUD/AXD. Participants will be randomized to one of two conditions: 1) treatment with the UP or 2) treatment with therapist-guided Take Control (TC; a computerized alcohol reduction program). In addition, in a subset of twenty-five participants, functional magnetic resonance scanning (fMRI) will be used to examine the effects of the UP on changes in brain activity in areas important to regulation of emotional and reward processes implicated in excessive alcohol consumption. The researchers' primary hypotheses are that the UP group will, compared to the TC group: 1) be superior in acute symptom reduction from pre- to post-treatment, and 2) evidence greater reductions in percent days heavy drinking, percent days of drinking per week, and alcohol craving.

Mood disorders, such as depression and bipolar disorder, are difficult to treat. One reason is that there are no objective ways to measure how these disorders affect the body and respond to different treatments. In this study, researchers want to perform tests on people undergoing clinical care for mood disorders. The purpose is to understand the experience of receiving treatment for depression, bipolar disorder, and suicide risk. We also hope that this study will help us to predict which medications will improve thoughts of suicide. People 18 years or older who are receiving treatment for depression, bipolar disorder, or suicide risk may take part in this study. Participants must have also been enrolled in protocol 01-M-0254. This study will be conducted at the NIH Clinical Center in Bethesda, MD. The study typically lasts up to 12 weeks, but may last longer if a participant s treatment continues past that time. Participants will have weekly interviews and questionnaires while they are being treated for their mood disorder. Other tests are optional and include psychological testing, blood draws, sleep tests, and imaging scans. These will be done at the start and the end of research participation....

The purpose of this protocol is to allow for the careful screening of patients and healthy volunteers for participation in research protocols in the Experimental Therapeutics and Pathophysiology Lab (ETPB) at the National Institute of Mental Health (NIMH) and for the collection of natural history data. In addition the protocol will allow clinicians to gain more experience in the use of a variety of polysomnographic and high-density EEG recordings. Subjects in this protocol will undergo an evaluation which may include: a psychiatric interview; a diagnostic interview; rating scales; a medical history; a physical exam; brain magnetic resonance imaging (MRI); electroencephalography (EEG); electrocardiography (EKG), magnetoencephalography (MEG); blood, saliva and urine laboratory evaluation; and a request for medical records. Subjects may also be asked to complete questionnaires about attitudes towards research and motivation for research participation. The data collected may also be linked with data from other mood and anxiety disorder protocols (e.g., brain imaging, DNA, psychophysiology tests, treatment studies, etc) for the purposes of better understanding the diagnosis, pathophysiology, and treatment response of patients with mood disorders. Parents of minors will be interviewed. Upon conclusion of the screening process, subjects will either be offered participation in a research protocol and will sign the appropriate informed consent, or will be considered not appropriate for participation in research and will be referred back into the community. The current protocol thus serves as an entry point for individuals with mood or anxiety disorders or healthy volunteers to enter NIMH IRB approved ETPB protocols....
