NCT00748995
This is a research study examining health effects of the Iraq War, especially those effects involving mental health. This study is a follow-up to the Neurocognition Deployment Health Study (NDHS), also called "Prospective Assessment of Neurocognition in Future Gulf-deployed and Gulf-nondeployed Military Personnel: A Pilot Study." The specific purpose of this research study is to find out more about the longer lasting effects of war on mood and stress symptoms, thinking and reaction skills, and different aspects of day to day life, such as work and daily activities. Survey and test results from previous participation in the NDHS will be compared to the new information that will be obtained from participants as part of this study. The investigators expect that a total of about 817 military personnel and military Veterans will participate in the study. There are two parts to this study: (1) mail/internet/phone survey and (2) in-person assessment. The investigators will invite all NDHS participants who deployed to Iraq to participate in the survey component. The survey component of the study involves being interviewed by phone about mood and stress symptoms and head injuries and completing written survey questions by either mail or on the internet that address basic personal history (such as age, military status, gender, combat injury history), mood, stress symptoms, and stressful experiences. The phone interview will take about 2 to 2.5 hours to complete. The questionnaire part will take about 20 to 30 minutes to complete, and can be completed either by mailing back completed questionnaires or by internet using a private, individual log-in/password combination. The investigators will invite approximately 200 selected at random from the larger group of survey responders to take part in the in-person assessment. The in-person assessment involves taking a small subset of neuropsychological tasks. The tasks will be given on a computer or using paper and pencil. Participants will also be asked to complete questionnaires about work, daily activities, and health history, as well as basic health measures such as height, weight, blood pressure, heart rate, and waist size. Potential participants will be given the option of completing the in-person assessment at one of the two study sites (Seattle or Boston), or in a private setting in their community (e.g., a hotel small conference room). Altogether, this part of the study will take about 120 minutes to 140 minutes to complete.
NCT06976801
Our null hypothesis is that micromotion tibial intramedullary fixation (IMFN) does not impact union or complication rates when compared to standard of care treatment with non-micromotion tibial nail fixation. There are no current or past randomized controlled trials comparing these fixation techniques to one another. There is good data supporting both the use of intramedullary fixation for tibial fractures alone, and in high-risk patient populations (open fractures, GSW tibial fractures). However, the effectiveness of these methods with respect to each other has never been investigated. The knowledge gained will allow us to potentially influence and adapt protocols to treat this patient population. Additionally, resources available at our institution provide a supportive framework with which to maintain contact with patients after hospital discharge. These key factors will allow us to perform a robust analysis of this population, to include outcomes measures of function and complications. With much of the limited existing literature on tibial nails being in very defined populations, without a strong comparison group there is no clear guidance on when the use of a micromotion device is indicated. Our approach to randomize our patients will reduce the bias that exists in the current literature and provide a robust spectrum of injuries to sub analyze and compare. Objectives Primary Objective Compare post-operative union rates in tibial shaft patients treated with 2 types of intramedullary rod fixation devices. Secondary Objective(s) Compare complication rates, patient reported outcomes, range of motion, pain and radiographic/sonographic outcomes in patients treated with tibial nails.
NCT04772170
Background: Respiratory viruses circulate throughout the year and around the globe. Wearable and sensor devices, like smartwatches, may be able to help monitor infectious diseases. Researchers want to use them to learn how respiratory viruses affect people in different ways. Objective: To use digital devices to collect data from participants in challenge studies that could indicate subtle changes in health during an infection that might otherwise go unnoticed. Eligibility: Healthy adults who have enrolled, were recently enrolled, or are scheduled to enroll in a challenge study. Design: Participants will stay at NIH for the duration of the challenge study (at least 9 days) and then will have outpatient follow-up visits (2-4). While at NIH, participants will wear a smartwatch at all times. It will record data like temperature, heart rate, breathing rate, and movements. Participants will have a smartphone that records at all times to listen for coughing and changes in voice. Participants will perform tasks every 4 hours during the daytime. They will record themselves coughing, breathing in deeply, and reading aloud. They will take videos of their face. They will play a game to test their reflexes and focus. They will measure their head temperature with their smartwatch. For outpatient visits, participants will use one smartphone and the smartwatch to complete the above tasks. Participants will be sent a smartwatch to wear at home at night to collect additional healthy data. Participation will last the duration of each challenge study, and may range from 10 weeks to 2 years.

This randomized study examines how well zinc works in improving quality of life in patients with gastrointestinal cancer that cannot be removed by surgery who are receiving chemotherapy. Zinc may help to improve patient's quality of life by preventing zinc deficiency.
NCT04494256
The ALSpire Study is a clinical trial evaluating the investigational drug BIIB105 in adults living with amyotrophic lateral sclerosis (ALS). The ALSpire Study consists of two parts: * Part 1: 6-month placebo-controlled study. During Part 1, participants are randomly assigned to receive either BIIB105 or placebo in a 3:1 or 2:1 ratio (depending on the participant's assigned Cohort). * Part 2: up to 3-year long-term open-label extension. During Part 2, all participants receive BIIB105. The objectives of the study are to evaluate: * The safety and tolerability of BIIB105 in people with ALS * What the body does to BIIB105 (also called "pharmacokinetics") * What BIIB105 does to the body (also called "pharmacodynamics") * Whether BIIB105 can slow the worsening of clinical function

Pelabresib (CPI-0610) is a small molecule inhibitor of bromodomain and extra-terminal (BET) proteins.
NCT03373227
This phase II, single-center, open-label study will evaluate the comparable efficacy of tacrolimus extended release tablets (Envarsus®) to the standard of care (SOC) twice daily tacrolimus (Prograf®) dosing regimen post-cardiac transplantation.
NCT04257578
This phase I/II trial studies the safety of acalabrutinib and axicabtagene ciloleucel in treating patients with B-cell lymphoma. Acalabrutinib may stop the growth of tumor cells by blocking key pathways needed for cell growth. Immunotherapy with axicabtagene ciloleucel is engineered to target a specific surface antigen on lymphoma cells. Acalabrutinib may enhance the efficacy of axicabtagene ciloleucel in treating patients with B-cell lymphoma.
NCT06697353
This is an observational study in which data already collected from people with chronic heart failure is studied. Chronic HFrEF is a long-term condition where the left side of the heart does not pump blood out to the body as well as it should. Blood and fluid may collect in the lungs, blood vessels, and tissues causing shortness of breath or tiredness. Over time, heart failure can lead to other serious medical conditions that may result in hospital stays or even death. The study drug, vericiguat, is already approved for doctors to prescribe to people with chronic HFrEF in Japan. Vericiguat increases the activity of an enzyme called soluble guanylate cyclase (sGC), which relaxes the blood vessels, allowing more blood to flow through. As a result, the heart is able to pump better. The participants in this study are already receiving treatment with vericiguat (newly initiated) as part of their regular care from their doctors. There is currently limited real-world data on the use of vericiguat in Japanese people. Therefore, more research is needed on larger groups of Japanese people for a longer period to understand the effects of use of vericiguat. The main purpose of this study is to collect information about how well vericiguat is used in Japanese people with heart failure who initiate vericiguat treatment. To do this, researchers will collect the following information for participants who newly initiated vericiguat: occurrence of death due to heart and blood vessel related events occurrence of death due to any reason hospital stays due to heart failure a combination of hospital stays due to heart failure or occurrence of death due to heart and blood-vessel related events a combination of occurrence of death due to any reason or hospital stays due to heart failure In addition, researchers will collect the following information: participants' characteristics, including age, sex, height, weight, and medical history how well did the participants follow their prescribed treatment with vericiguat over the year after starting it how long did the participants continue to take vericiguat over the year after starting it changes in the dose of vericiguat in the participants over the year after starting it other treatment options participants have taken for the treatment of heart failure changes in laboratory values and other test results before and after treatment with vericiguat The data will come from the participants' hospital records provided by the Medical Data Vision Co., Ltd. They will cover the period from September 2016 to July 2024. Researchers will track participants' data and will follow them for a maximum of one year after starting treatment with vericiguat, or until any of the following happens: the participant dies the participant cannot be tracked anymore the end of the study In this study, only available data from routine care are collected. No visits or tests are required as part of this study.

NCT07187362
This study involves the assessment of alternatives to iliac bone graft during spinal fusion surgery. Four types of bone graft alternatives are being compared to iliac bone graft during the posterior portion of an anterior/posterior one-level lumbar spinal fusion. If you choose to participate in this study, you will be randomized (like a flip of a coin) to receive either your own iliac bone graft, bone morphogenetic protein (BMP, made from proteins found in the human body that stimulate bone growth), or one of the following stem-cell based bone graft alternatives for the posterior portion of your fusion surgery: * Orthofix Trinity-made from donor bone and bone marrow stem cells * Allosource Allostem-made from donor bone and fat stem cells * Nutech Nucel-made from donor bone and placenta (after birth) stem cells Each bone graft alternatives has been approved by the United States Food and Drug Administration (FDA) and is commercially available with the exception that BMP application is considered "off-label". That is, BMP it is not approved for this indication, it is currently indicated for anterior fusion. The volume of bone graft that you will receive is the same for each graph type (approximately 5cc). Approximately 150 patients from the Midwest Spine and Brain Institute are expected to be enrolled in this study. If you choose to take part, your participation will last about 2+ year. At approximately 9 - 15 months after your surgery, you will be asked to return to the Midwest Spine and Brain Institute to undergo a limited CT scan of the fusion level to determine how you are healing. Your pain level and functional ability will also be evaluated at this visit.
NCT07211555
This study is being done to evaluate a new robotic system that helps urologists more precisely reach the kidney during surgery to remove large kidney stones. The procedure, called percutaneous nephrolithotomy (PCNL), is typically used for people who have large or difficult-to-remove kidney stones. Traditionally, many urologists rely on radiologists to place a tube into the kidney before surgery. This can cause delays, require multiple procedures, and increase costs. The robotic system being studied - called LARC - is designed to help the urologist safely and accurately guide a needle directly into the kidney during the surgery, without needing a separate procedure beforehand. The robot uses live X-ray images to help align the instruments. Although parts of the robot have been approved by the U.S. FDA, the version used in this study is still investigational and not yet approved for this specific purpose. The study will take place at AdventHealth Celebration and include up to 45 adult patients who are scheduled for PCNL surgery. Participants will be followed for up to 1 month after surgery, and doctors will look at outcomes such as the success of the procedure, the number of kidney stones removed, complications, time in surgery, and radiation exposure. This research may help make kidney stone surgery safer, faster, and more effective in the future.
NCT07212413
This study is designed to compare two modern techniques used to restore decayed back teeth with tooth-colored filling materials. Some patients experience temporary discomfort or sensitivity after these types of dental treatments. The purpose of this study is to learn whether one technique may help reduce this short-term sensitivity compared to the other. Adults who need fillings on both sides of their mouth are invited to participate. Each patient will receive one filling using each technique, placed in different teeth during the same appointment. The procedures will be performed using standard clinical methods and materials. After treatment, participants will be contacted by telephone to report any discomfort at several time points during the first week. The interviewer will not know which technique was used for each tooth to ensure unbiased reporting. This information will help dentists better understand how these techniques affect patients' comfort in the days following treatment.
NCT07212751
The study aims at determining if the presence of adverse plaque features identified from the CT angiogram can help determine prognosis and guide treatment options.
NCT07212933
This project employs a prospective, double-blind, randomized controlled trial methodology to comparatively analyze the safety and survival outcomes of human umbilical cord blood RAK cells applied in advanced gastric cancer. Firstly, the maximum tolerated dose (MTD) of RAK cell therapy for patients with advanced gastric cancer will be determined through a dose-escalation trial. Subsequently, the overall survival (OS), progression-free survival (PFS), and incidence of adverse events will be compared between the RAK treatment group and the control group. This aims to explore the efficacy and safety of biotherapy for recurrent or metastatic gastric cancer where frontline therapy has failed, thereby laying the foundation and providing evidence for large-scale, multi-center clinical studies.
NCT07203079
The goal of this study is to compare whether oral or intravenous acetaminophen works better for pain control in patients undergoing lumbar spine fusion surgery
NCT07213141
It is well known that an infection can be a triggering factor for the development of autoimmune thyroid disease. The COVID-19 pandemic was an example of this, with several reports of both subacute thyroiditis as well as Graves' disease occurring after experiencing SARS-CoV-2 disease. There have also been cases of Graves' disease reported after COVID-19 vaccination administration (\<4 weeks between the vaccine and the development of hyperthyroidism). However, the current evidence is of low quality and consists mainly of case reports. A search strategy on October 3, 2022, in the medical database PubMed could only retain one retrospective study on this subject. In this study by di Filippo et al., approximately 64 new cases of Graves' disease with hyperthyroidism were identified in the Milan region, Italy, in the year 2021, of which 20 patients had an onset within 4 weeks following COVID vaccine administration (31.2%). The investigators would like to increase the knowledge about the possible link between COVID-19 (both the disease and the vaccination) and Graves' disease, by means of a case-control analysis of all 'de novo' cases of Graves' hyperthyroidism described in the C.H.U. Brugmann. The investigators want to investigate whether Graves' disease after vaccination would be clinically different from the "classic" Graves' disease, thereby describing factors such as the duration of the disease, the level of thyroid-stimulating immunoglobulins (TSI), the percentage of T3-dominant Graves' disease, or the dose of thyreostatics (such as strumazole) required to control the disease.
NCT07212842
Introduction: Fluid overload and systemic inflammation are major contributors to postoperative complications in patients undergoing cardiac surgery with cardiopulmonary bypass (CPB). Objective: To evaluate the effects of blood washing with methylene blue during zero-balance ultrafiltration (ZBUF) on fluid overload and systemic inflammatory response. Methodology: Fluid status was assessed using the InBody S10 precision bioimpedance device, measuring extracellular water (ECW), total body water (TBW), intracellular water (ICW), and the ECW/TBW ratio. Pulmonary congestion and intravascular volume were evaluated separately using a Philips Lumify S4-1 transducer with a Samsung tablet. Pulmonary congestion was confirmed by the presence of B-lines on lung ultrasound. Intravascular volume was assessed via the inferior vena cava (IVC) distensibility index (DI) during mechanical ventilation and collapsibility index (CI) during spontaneous breathing. Inflammatory cytokine levels were measured using a Luminex xMAP-based multiplex immunoassay.
