Depression is a very common disorder that is most often chronic or recurrent in nature. Many subjects do not respond adequately to an initial antidepressant treatment trial. Subjects who do not respond adequately to multiple therapeutic interventions are considered to have treatment-resistant depression (TRD). Among the treatment options for subjects with TRD is Vagus Nerve Stimulation (VNS) Therapy.This blinded, randomized, multicenter controlled study is intended to collect evidence that VNS Therapy as an adjunctive therapy improves health outcomes for patients with TRD.

Meniere's disease is a common cause of vertigo that becomes more common with age. Unfortunately, Meniere's disease and vestibular migraine have significant overlap and are sometimes difficult to diagnose. This is due to a lack of understanding of the true cause of Meniere's disease. Due to the lack of a biomarker (an objective test), the diagnosis of Meniere's disease has been based on clinical history and hearing loss. We are exploring ways to differentiate Meniere's disease and vestibular migraine, potentially through a lab test. In addition, identifying biomarkers may help early diagnosis and direct more personalized treatment strategies, especially early on before hearing loss occurs.

This study is for patients that have been diagnosed with non-small cell lung cancer. The purpose of this study is to find out if a targeted immunotherapy treatment will have an effect on specific genes and proteins in tumors. This is a screening study in which a tumor sample will be submitted for testing. Based on results, the participant will be assigned to one of the treatment sub-studies.

This is an observational study that will analyze electronic health records data from real-world populations and settings in order to fully characterize the outcomes of Lung Cancer Screening with Low-Dowse CT scans.

The largest published COVID-19 pediatric series to date included only 13 patients considered to be critically ill and only described the Chinese outbreak. There are essentially no data outside of this and nothing to begin to understand the prevalence of severe/critical pediatric COVID-19, the risk factors associated with this illness, outcomes from COVID-19, and factors (patient or treatment) that may be associated with an improved or worsened outcome. This study will identify all children admitted to an inpatient unit with a diagnosis of COVID-19. Clinical data will be collected through medical record review to describe in detail the demographics and clinical characteristics, including clinical course and treatment, of infected children who require hospitalization.

The purpose of this study is to develop transcranial magnetic stimulation (TMS), specifically TMS at a frequency known as theta burst stimulation (TBS), to see how it affects the brain and changes the brain's response to alcohol-related pictures. TMS and TBS are stimulation techniques that use magnetic pulses to temporarily excite specific brain areas in awake people (without the need for surgery, anesthetic, or other invasive procedures). TBS, which is a form of TMS, will be applied over the medial prefrontal cortex, (MPFC), which has been shown to be involved with drinking patterns and alcohol consumption. This study will test whether TBS can be used as an alternative tool to reduce the desire to use alcohol and reducing the brain's response to alcohol-related pictures.

The Advanced Cardiac Therapies Improving Outcomes Network (ACTION) is a distributed network-based learning health system (LHS) of care centers, clinicians, researchers and industry representatives partnering with patients who have heart failure and their caregivers with the ultimate aim of achieving health, longevity and quality of life equivalent to the general population. See https://www.actionlearningnetwork.org for more information. The initial focus will be to apply structured quality improvement methods, advanced information technology systems, and sharing of best practices to track and continuously improve health-related outcomes for children with heart failure requiring advanced therapies. In the future, we plan to collaborate with other established registries and learning network (i.e. UNOS, PHTS and Cardiac Networks United) to create an integrated network that improves care throughout all phases of a patient's illness including chronic heart failure, acute decompensated heart failure, ventricular assist device support and transplant.

This study is for patients that have been diagnosed with Acute Myelogenous Leukemia (AML). This study will compare standard chemotherapy using daunorubicin, cytarabine and gemtuzumab ozogamicin (GO) to chemotherapy using an experimental drug called CPX-351. CPX-351 is made up of daunorubicin and cytarabine. CPX-351 is made in a way that makes the drugs stay in the bone marrow longer and may be more effective. CPX-351 has been shown to be well-tolerated and effective against leukemia in adults and children. Participants can expect to receive treatment on this study for 6 months and followed for up to 10 years.

This Phase II clinical research study evaluates both the safety and effectiveness of an FDA-regulated medication presently in the initial stages of development for alcohol use disorder treatment (GET73), and will test whether GET73 alters brain chemicals and function, response to alcohol ingestion, and the desire for alcohol. Participants will be randomly assigned to one of two medication treatment groups (GET73 or placebo). Study medication will be taken for 8 days, with approximately 4 study visits, and a "bar-lab" procedure and 2 MRI brain imaging scans will be completed. Questionnaires and clinical interview measures will be completed at study visits along with consistent assessment of potential side effects from study medication.

The purpose(s) of the research is to test a new medication in combination with a talk therapy for Veterans experiencing posttraumatic stress disorder (PTSD) and who may have alcohol use disorder (AUD). The study consists of 12 weekly therapy sessions. Once per week before each therapy session, an intranasal dose of investigational medication will be administered. The study also involves 3 and 6-month follow-up appointments and the administration of questionnaires at each visit.
