There are about 173942 clinical studies being (or have been) conducted in United States. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Tranexamic acid (TXA) is a synthetic, competitive lysine receptor inhibitor on plasminogen. It ultimately stabilizes the fibrin matrix, therefore used as a hemostatic agent for various indications. While there has been indications for orthopedic and trauma surgery, there is no clear data for its role in patients who are undergoing free tissue transfer. Studies have shown that patients undergoing free tissue transfer can have transfusion rates ranging from 7.2% to 34.9%, which data also showing association between transfusion requirement and higher free flap failure rate. There has been a few retrospective studies that evaluated the effect of TXA in free tissue transfer and the results showed no increased risk of microanastomosis failure but some showing decreased blood loss. This study aims to further analyze the role of TXA in patients undergoing breast free flap reconstruction with randomized, prospective trial. Control group will not receive TXA while experimental group will receive TXA. Both groups will receive standard of care breast free flap surgery as well as post-op care, which is streamlined with Early Recovery After Surgery (ERAS) protocol. Their pre and post-op hemoglobin will be compared, as well as rates of transfusion, surgical outcome and surgical complications including hematoma, flap failure, and any other medical complications such as Deep Vein Thrombosis (DVT)/ Pulmonary Embolism (PE).
Nitropaste is a topical agent that contains 2% nitroglycerin. It is an effective vascular smooth dilator, with more powerful effect on venous vasculature than arterial vasculature. While its main indication is for angina pectoris, there have been many studies showing improved survival of axial and random pattern flaps. Furthermore, recent clinical studies highlight significantly decreased mastectomy flap wound complication and need for sharp debridement. Nitropaste has low rates of side effects and is very well tolerated in general. To this date, there's no study that investigates its utility on patients who are undergoing chest masculinizing surgery. The purpose of this study is to investigate the potential utility of nitropaste in reducing rates of wound complications in patients undergoing chest masculinizing surgery.
The objective of this study is to see the amount of systemic absorption of a standard dose of dexamethasone oral rinse for patients with symptomatic oral lichen planus (OLP) or oral lichenoid reactions (OLR) and healthy subjects (those who do not have OLP or OLR aka the control group).
The purpose of this study is to construct a multi-site, prospective registry to evaluate the clinical outcomes of patients who have undergone gastric fundus mucosal ablation at True You Weight Loss.
The purpose of this study is to compare the short-term and long term impacts of Food is the Best Medicine (FBM)-Virtual on diet quality, food security status, breastfeeding rates, mental health status, rates of home cooking, and rationing coping strategies relative to FBM-In Person among food insecure, postpartum women and to compare implementation outcomes across the FBM-Virtual and FBM-In Person using process data collected from the participants, Community Health Worker (CHW)s, and partner organizations.
The purpose of this study is to understand the acute, short-term and long-term impact of transcutaneous and/or percutaneous electrical stimulation with afferent-specific electrical stimulation (asES) on proprioception and fine motor control in the upper extremity. For this purpose, the researchers will use transcutaneous and/or percutaneous asES, high-density electromyography (HD-EMG), arm kinematic measurements, and standardized clinical assessments. This study will be conducted in healthy able-bodied individuals and patients with essential tremor (ET).
Phase 1 study to determine the safety and tolerability of QTX3046 as a single agent or in combination with cetuximab.
Overall Objective: To determine the efficacy of rbLf supplementation in a healthy adult population, specifically with regard to iron regulation (primary), gut health (secondary), and immune function (secondary). Purpose: The purpose of this study is to determine the effects of rbLf on iron regulation, exercise performance, gut health, and immune function as compared to cow's milk derived bLf. Participants: To account for an approximate ~10% dropout rate (and rounding up to ensure equal number of enrolled participants per group), n=25 per group for males (N=50) and n=30 per group for females (N=60) will be enrolled for a total sample size of N=110. Procedures: Participation in this study will include 6 in-person visits over 14 weeks. Anemia will be checked and excluded at the first visit using a single finger prick, followed by a 10-20 min exercise test on a treadmill to evaluate exercise capacity. On visit 2 participants will perform three 3-15 minute exercise tests on a treadmill with rest in between each test in order to determine exercise performance. A finger prick will be performed before and after each run to determine lactate levels. After visits 2 participants will be randomized to their respective supplement group recombinant Bovine Lactoferrin supplement (rbLf) (Male and Fame), a bovine-milk derived Lactoferrin supplement (Female), or a placebo (Male) once daily for 4 weeks. Blood samples will be obtained prior to and after each supplement phase to determine change in iron levels and red blood cell capacity. After a 2-week washout participants will return to complete the same testing outcomes and will receive the subsequent supplement. At visit 6 a final blood sample will be collected.
This will be a prospective, randomized study performed at a single tertiary referral academic medical center (University of California San Francisco, CA), evaluating the survival benefits of levothyroxine compared with no levothyroxine for patients who have undergone heart transplant. It will be double-blinded and placebo-control; participants will be randomized to receive levothyroxine or receive no levothyroxine.
The purpose of this study is to determine whether newly diagnosed high-grade glioma(s) that cannot be removed surgically change as a result of the study treatment; and to identify and evaluate the potential side effects (good and bad) of the study treatment in patients with newly diagnosed high-grade glioma(s) that cannot be removed surgically.
