Active clinical trials for "Syndrome"

Every year, approximately 2 million people in the United States and 280,000 in Canada experience a mild traumatic brain injury/concussion. In patients with concussion, symptoms experienced following injury usually get better within 3 months. However, approximately 5-25% of people will experience symptoms beyond the 3 month period, characterized by persistent headaches, fatigue, insomnia, anxiety, depression, and thinking or concentration problems, which contribute to significant functional impairment. Chronic headache is the most common symptom following concussions. They can last beyond 5 years following injury, significantly impacting daily activities. To date, post-concussion symptoms have no known "cure". One potential approach to treating post-concussion symptoms may involve using drug-free interventions, such as neuromodulation therapy. This has the goal of restoring normal brain activity. Repetitive transcranial magnetic stimulation (rTMS) is one method currently being explored as a treatment option. TMS is a procedure where brain electrical activity is influenced by a magnetic field. Numerous studies using rTMS to treat other disorders, such as dementia, stroke, cerebral palsy, addictions, depression and anxiety, have shown much promise. The primary objective of this study is to determine whether rTMS treatment can significantly improve persistent post-concussion symptoms. A secondary objective is to explore the relationship between potential changes in brain function and clinical markers associated with rTMS treatment and how functional near-infrared spectroscopy (fNIRS), a neuroimaging technology, may be used to assess rTMS-treatment response.

The objective of the current study is to evaluate the effect of a probiotic mixture on the adequate relief and faecal microbiota in obese patients with irritable bowel syndrome

This study aimed to investigate the impact of intensive cholesterol-lowering therapy (including evolocumab), drug treatment for high-risk plaques (Vulnerable plaques) with a high probability of developing acute coronary syndrome. The purpose of this study is to determine the effect of the change in the Lipid core burden index and compare the rate of cardiac events over 12 months following cholesterol therapy.

This study is investigating the immediate and long-term effects of bilateral cerebellar transcranial direct current stimulation on cognition, balance, and symptom severity in people with sports-related post-concussion syndrome. The central hypothesis is that tDCS will provide improvements in cognitive deficits, balance, and overall symptom attenuation in people with SRPCS both acutely and at 2 and 4 week follow ups. The researchers further hypothesize that cerebellar tDCS will ameliorate the symptoms of people with SRPCS.

The purpose of this study is to determine the effect of fiber supplementation on the fecal metagenome and metabolome in relation to symptoms and anorectal physiology in post-menopausal women with irritable bowel syndrome with diarrhea suffering from liquid stool fecal incontinence (FI.)

Background: Allogeneic hematopoietic stem cell transplant involves taking blood stem cells from a donor and giving them to a recipient. The transplants are used to treat certain diseases and cancers. Researchers want to see if the transplant can treat VEXAS Syndrome. Objective: To see if stem cell transplants can be successfully performed in people with VEXAS and even improve the disease. Eligibility: People ages 18-75 who have VEXAS Syndrome that has caused significant health problems and standard treatment either has not worked or is not available. Design: Participants will be screened with: Physical exam Medical review Blood and urine tests Heart and lung function tests Bone marrow biopsy Participants will have a chest x-ray. They will have an imaging scan of the head, chest, abdomen, pelvis, and sinus. They will have a bone density scan. They will have a dental exam and eye exam. They will meet with specialists. They will repeat some screening tests. Participants will be admitted to the NIH hospital. They have a central venous catheter put into a vein in the chest or neck. They will receive drugs to prepare their bone marrow for the transplant. They may have total body irradiation. They will receive the donor stem cells through the catheter. They will get other drugs to prevent complications and infections. After discharge, they must stay in the DC area for 3 months for weekly study visits. Participants will have study visits 30, 60, 100, 180, 210, 240, 300, and 360 days later. After that, they will have yearly visits for 2 years and then be contacted yearly by phone....

Hardening of the blood vessels, called arterial stiffness, is a risk factor for future heart disease and its causes are unclear. The proposed study will 1) randomly assign adolescents at high risk of stiffening blood vessels to take a protein supplement called carnitine and study its effects on arterial stiffening and 2) study carnitine related genes for their effect on arterial stiffening. The study will definitively establish a role for carnitine action as a cause of stiffening blood vessels and signal a way to treat or prevent stiffening.

Proof of concept, double-blind, randomized, placebo-controlled trial with d-methadone proposed for the first time for use in the treatment of patients diagnosed with primary, moderate to very severe Restless Legs Syndrome (RLS). Its glutamatergic mechanism of action might be effective on RLS arousal pattern and sleep disturbance which highly impair the quality of life of RLS's patients. Patients will take the study drug/placebo once a day for 30 consecutive days.

1.0 BACKGROUND Postural tachycardia syndrome (POTS) is a disorder of chronic orthostatic intolerance characterized by symptoms of palpitations, lightheadedness, chest discomfort, shortness of breath, blurred vision, and mental clouding. These symptoms occur during standing and are associated with a marked increase in heart rate (HR) in the absence of hypotension, which typically resolve when sitting or lying down. Most importantly, POTS is associated with a very poor quality of life and significant functional disability. POTS patients commonly experience mental clouding ("brain fog") even while lying down or seated, which poses significant limitations to daily activities . Unfortunately, there is a relative paucity in the literature assessing therapies for POTS patients. Given that excessive tachycardia on standing is a fundamental component of this syndrome, a handful of studies have evaluated medications that reduce HR. Ivabradine is newer drug that is a selective If channel blocker that reduces HR without affecting other cardiovascular functions. 2.0 RATIONALE / STUDY PURPOSE The investigators propose to compare the efficacy of propranolol and ivabradine on HR response to standing, and symptom burden in patients with POTS. 3.0 Study Design This will be a single-center double-blind placebo-controlled randomized crossover trial conducted in patients with POTS to compare effects of (1) oral ivabradine 5 mg bid plus placebo BID (to fill out a QID schedule); (2) oral propranolol 10 mg qid; and (3) oral placebo qid in POTS patients. After a baseline screening assessment following a washout period of 7 days, participants will be randomized to start with a 4-week course of either ivabradine, propranolol or placebo. The other two treatments will be given in separate 4-week courses with a 7-day washout period between phases, with each participant acting as his or her own control. At the end of each 4-week phase, participants will complete the symptom-rating and HRQOL questionnaires, and also undergo tilt table testing to assess the change in HR at 10 min with head up tilt. Participants will undergo POTS testing at baseline and at the end of each 4-week treatment course. This will involve a total of 4 separate study visits.

Another term for myelodysplastic syndrome is bone marrow failure. The bone marrow is where components of blood such as red cells, platelets and white cells are made. In bone marrow failure, the ability for bone marrow to make these cells is decreased. In myelodysplastic syndrome, this decreased bone marrow function is believed to result from abnormalities that prevent the normal maturation process by which bone marrow cells develop into red blood cells, white blood cells and platelets. In myelodysplastic syndrome, these abnormal bone marrow cells occupy space in the bone marrow and prevent the function of remaining normal bone marrow cells. One approach to treating the abnormal growth of immature cells is to give chemotherapy which damages DNA within these cells and causes their death. Unfortunately, such therapy has side-effects, since even normal cells can be affected by the treatment. Both 5-azacitidine (5AZA) and decitabine (DEC) are FDA-approved to treat MDS. In this study, 5AZA and DEC will be administered using an alternating low doses schedule in an attempt to overcome the known mechanisms of resistance to the administration of 5AZA or DEC as single agents caused by automatic adaptive shifts in DNA metabolism.
