NCT ID: NCT04543513 Withdrawn - PTSD Clinical Trials

Self-regulation of Prefrontal Cortex During Emotional Cognitive Control in PTSD

SPrC-PTSD
Start date: January 1, 2023
Phase: N/A
Study type: Interventional

Deficits in emotional cognitive control are present in a number of clinical psychiatric populations including depression, anxiety, and PTSD. Deficits in this domain of function limit one's ability to focus attention on goal-directed activities while inhibiting reactions to irrelevant emotional stimuli, and this contributes to the symptoms of these disorders and makes individuals less likely to be successful in existing treatments. The left dorsolateral prefrontal cortex (LDLPFC) and its connectivity with other regions (i.e., dorsal anterior cingulate cortex, ventromedial prefrontal cortex, insula, amygdala) is thought to play a central role in facilitating emotional cognitive control. However, past research has primarily utilized correlational approaches that limit conclusions about the directionality of these relationships. Enhancing our understanding of the neural underpinnings of emotional cognitive control could be valuable for informing treatment for populations with deficits in these processes, such as adults with PTSD. The current study utilizes a neuromodulatory approach called real-time functional magnetic resonance imaging neurofeedback (rtfMRI-nf) whereby participants observe their own neural activity in the moment and are taught to self-regulate this activity. Adult volunteers, who have been diagnosed with PTSD, will be trained to increase neural activity in LDLPFC while involved in mental tasks involving emotional cognitive control processes. The mental tasks will include counting, remembering words, or planning events while viewing negatively-valenced emotional words (e.g., kill, death, threat). Participants in this study will complete a non-randomized LDLPFC rtfMRI-nf protocol to assess tolerability and feasibility of the protocol in a clinical population of interest. Resting-state fMRI scans and behavioral testing sessions will take place before and after rtfMRI-nf. The specific aims are to examine the impact of LDLPFC rtfMRI-nf on: (1) LDLPFC activity during emotional cognitive control, (2) LDLPFC functional connectivity with other brain regions during rest, and (3) cognitive control task performance. As this study is meant to be preliminary, the target sample size is not powered to detect statistical significance for these measures. However, effect size estimates will be calculated to provide potential justification for future work with this protocol in this clinical population. To these ends, this study will use rtfMRI-nf to examine preliminary evidence of a novel protocol to regulate LDLPFC activity in adults diagnosed with PTSD. This research will improve our understanding of emotional cognitive control and demonstrate whether this is a modifiable target for intervention in this clinical population of interest.

NCT ID: NCT04540523 Withdrawn - Physical Activity Clinical Trials

Home-Based Exergaming Intervention

Start date: September 8, 2020
Phase: N/A
Study type: Interventional

This study will employ a 3-arm randomized clinical trial to determine the effects of a 6-month home-based exergaming intervention on preschoolers' physical activity, health-related fitness, cognition, and screen time, across time, at 3, 6 and 12 months, and as an exploratory outcome, will explore the moderating effects of parent involvement and physical home environment on the intervention role of exergaming across time. Briefly, a total of 330 child-parent dyads from the Twin Cities area in Minnesota will be individually randomly assigned to: 1) an exergaming intervention group (30 min. per session, 5 sessions exergaming play per week for a 6-month period); 2) a traditional PA group (phone consultations and workshops for parents to offer 5 times 30 min. PA at home for 6 months); and 3) an attention control group (continue with usual activities at home with emailed PA tips).

NCT ID: NCT04538196 Withdrawn - Resident Education Clinical Trials

Coding Improvement Project: Resident Education on Documentation

DER
Start date: April 14, 2015
Phase: N/A
Study type: Interventional

Most General Surgery program directors have expressed the necessity to educate residents on the business aspect of medicine. However, the literature review did not produce any interventional studies directly addressing coding and documentation in General Surgery Residents. The purpose of this study is to address specific coding and documentation mistakes as identified by surgery coding analysts in the surgical department. Through this examination, we hope to provide residents with the necessary tools and framework for adequate documentation throughout their surgical careers.

NCT ID: NCT04536922 Withdrawn - Clinical trials for Metastatic HPV-16 Positive Squamous Cell Anal Cancer

Administration of Autologous T-Cells Genetically Engineered to Express T-Cell Receptors Reactive Against Mutated or Viral Neoantigens in a Patient With Metastatic Cancer Plus the Administration of Pembrolizumab

Start date: January 27, 2021
Phase: Phase 2
Study type: Interventional

Background: A cancer treatment has been developed called "gene transfer" or "gene therapy." It involves taking white blood cells from a person (called apheresis), genetically modifying the cells in a lab to recognize cancer, and then giving the cells back to the person. Researchers want to see if this treatment can help people with metastatic squamous cell anal cancer. Objective: To see if treating cancer with a person s own white blood cells that have been genetically modified can cause tumors to shrink. Eligibility: People who have metastatic squamous cell anal cancer for which standard treatments have not worked. Design: Participants will have had a tumor biopsy and apheresis to collect white blood cells under a separate protocol. Participants will stay at the hospital for 3 to 4 weeks. They will have an intravenous (IV) catheter placed in a large vein in the upper chest. Participants will get chemotherapy drugs (fludarabine and cyclophosphamide), the cell infusion, and aldesleukin through the IV. Pembrolizumab is given before and for three doses given every three weeks after the cell infusion. Aldesleukin will help the cells grow. Participants will take an antibiotic, antiviral, and antifungal by mouth. They will get an injection of filgrastim. It will stimulate the formation of white blood cells. Participants will have blood and urine tests. They will have physical exams. Their symptoms will be reviewed. They will have imaging scans. About 6 and 12 weeks after they finish treatment, participants will have safety follow-up visits. These visits will take 1 to 2 days. Participants will return to the Clinical Center every 3 to 6 months for 3 years, and then as determined by their doctor. They will be followed long term for up to 15 years on a separate study.
