NCT06817993
There has been much interest in the potential role of social media (SM) use in driving a current mental health crisis among teens, with a dire need for evidence that goes beyond self-report. One important avenue is to understand the role of the brain in driving the effects of SM use on emotional health and vice versa. However, there is almost no research addressing these questions, largely due to a lack of tasks that can probe the neural correlates of modern SM use. The goal of this clinical trial is to develop and validate a new developmentally-appropriate and ecologically-valid functional magnetic resonance imaging (fMRI) and eyetracking task, the TeenBrainOnline (TBO) Task, that is more realistic and similar to modern SM platforms. Participants will be 50 teens (ages 13-17) with depressive symptoms who will complete the final version of TBO task during fMRI with eye-tracking, an older Chatroom Interact (CHAT-I) Task, daily surveys of SM use, and measures of depressive symptoms. Our goal is to show that the task works by: * Demonstrating that it activates expected regions of the brain and visual attention biases toward feedback cues. * Showing that brain and eyetracking (visual attention) activity on the task explain variability in depressive symptoms at baseline and three months later, and work better than similar indices from an older task. * Showing that brain and eyetracking (visual attention) activity on the task are associated with real-world measures of social media use collected during daily surveys. Specifically, The investigators expect that teens whose brain and eyetracking activity suggests they are more sensitive to feedback on SM will report a social evaluation orientation toward social media use in daily life, such as engaging a lot in social comparison, worrying about missing out, and caring about getting a lot of likes and comments. Participants will be asked to: * complete a 10-15 minute screening call to determine eligibility for the study * complete one 90 minute virtual study visit to complete questionnaires and prepare for the MRI visit (visit 1) * submit 24 photos to our study specific social media site * complete an (in person) MRI scan visit (\~4 hours), which consists of 2 tasks where they will interact with peers (visit 2) * complete \~5 minute smartphone surveys 3 times a day for 16 days, asking about their daily experiences online and emotional reactions. * complete 2 online questionnaires asynchronously 3 months after their scan date
NCT02616484
The objective of this research study is to conduct a pivotal phase 3 trial of treatment with the investigational drug dichloroacetate (DCA) in young children with deficiency of the pyruvate dehydrogenase complex (PDC). PDC deficiency (PDCD) is the most common cause of congenital lactic acidosis and is a frequently fatal metabolic disease of childhood for which no proven treatment exists. The investigators predict that DCA represents targeted potential therapy for PDCD because of its ability to increase both the catalytic activity and stability of the enzyme complex. The conclusions of numerous laboratory and clinical investigations are consistent with this postulate and have led to the designation of DCA as an Orphan Product for congenital lactic acidosis by the Food and Drug Administration. A novel Observer reported outcome (ObsRO) survey that is completed by study participant's parent/caregiver, is the efficacy outcome measure. Funding Source - FDA OOPD
NCT06603064
Investigators are conducting this study to test if temporarily and non-invasively stimulating the brain will affect the emotional response to stress in healthy participants. Participants will perform a series of tasks while completing an MRI scan. After this, participants will be randomized to undergo transcranial magnetic stimulation (TMS) at two visits, undergoing active stimulation at one visit and undergoing 'sham' stimulation at another visit. Immediately following both stimulation sessions, participants will repeat the tasks during MRI scanning.

NCT05141006
Interstitial Cystitis/Bladder Pain Syndrome (IC/BPS) is a chronic and debilitating urological complex of disorders characterized by symptoms of bladder pain or discomfort, mostly upon bladder filling, and often accompanied by lower urinary tract symptoms (LUTS). This study will assess how safe and effective BOTOX (onabotulinumtoxinA) is in treating IC/BPS. Adverse events and change in disease symptoms will be evaluated. BOTOX (onabotulinumtoxinA) is an investigational drug being developed for the treatment of Interstitial Cystitis/Bladder Pain Syndrome (IC/BPS). Study doctors randomly assign the participants to 1 of 2 groups, called treatment arms, to receive BOTOX or placebo. There is a 1 in 2 chance that participants will be assigned to placebo. Approximately 80 female participants, aged 18 to 75 years, with a diagnosis of IC/BPS will be enrolled in approximately 40 sites in the United States and Canada. Participants will receive BOTOX or placebo injected into the bladder on Day 1 and will be followed for at least 12 weeks in treatment 1. Eligible participants may request additional dose of BOTOX between Weeks 12 and 24, and will be followed for 12 weeks in treatment period 2. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.

NCT05080218
The COVID-19 VaccinE Response in Rheumatology patients (COVER) study is a multicenter randomized controlled trial designed to evaluate the efficacy and safety of a mRNA COVID-19 vaccine supplemental dose (booster) in patients with autoimmune conditions and to evaluate the impact of different immunomodulatory therapies on vaccine response. The investigators propose to recruit up to 1000- patients with autoimmune conditions who have a completed 2-dose regime of mRNA COVID-19 vaccine (\>28 days prior) and who are planning to receive an additional dose of mRNA COVID-19 vaccine (i.e., booster). Participants in this study will be men and women 18 years and older with confirmed rheumatic disease, including psoriatic arthritis (PsA), axial spondyloarthritis (SpA) and rheumatoid arthritis (RA) who express a decision to receive the mRNA vaccination booster within 30 days post enrollment. A primary objective of this study is to test the hypothesis that holding certain medications for a brief period of time around the time of COVID-19 vaccination might improve the response to the vaccine while not unduly having safety concerns with respect to the effects of their disease. During the study, participants using the immunomodulatory therapies described outlined in protocol will be randomized to temporarily hold (for 2 weeks) versus continue after they receive the COVID-19 vaccine supplemental dose. Patients who temporarily stop one of their medications for their autoimmune inflammatory disease may be at increased risk of flares of their autoimmune condition. If these occur, they are expected to occur within 2 - 4 weeks of treatment interruption. Detailed protocol outlines the hold schedules for the therapies to be randomized in this study.
NCT06954805
The purpose of this study is to find out if there is a benefit to giving rituximab with etoposide, prednisone, vincristine, cyclophosphamide and doxorubicin (R-EPOCH) in participants who have high-risk B-cell PTLD in their 2nd phase of treatment (consolidation) while those with low-risk disease will be spared of chemotherapy and treated with rituximab consolidation alone. This study is also being done to find out about the usefulness of circulating tumor DNA (ctDNA), a novel blood test which, has been shown to help guide treatment decisions in other types of lymphoma. The goal is to answer the question if ctDNA is a viable and informative tool in treating PTLD with the hope that in the future it may be used to individualize study treatment for participants with PTLD in a way that limits study treatment toxicity without losing the effectiveness of the treatment plan.
