Filter by:T-REX HMB is a pilot randomized controlled trial (RCT) designed to assess the feasibility of a full trial comparing tranexamic acid (TXA) to placebo in decreasing HMB in premenopausal individuals anticoagulated for VTE. Strong data supports TXA as an effective and safe agent at decreasing HMB in the general population, but its use in those with VTE has been limited by a lack of data for its efficacy in anticoagulated individuals and theoretical concerns of its prothrombotic effects.
Hemorrhagic Myocardial infarctions are at high risk for mechanical complications including cardiac rupture. Prediction of vulnerable myocardial segments is an important step for the stratification of hemorrhagic MI patients. Wall motion index ratio is an important parameter to determine regions of high vulnerability within the 17-segment LV model of hemorrhagic MI.
In spine surgery, it is important to try to minimize bleeding. In particular, spine surgery often involves inserting hardware into bone, and/or removing bone in the spine. Because the bone in the spine contains blood vessels, there can often be bleeding from the bone itself that is difficult to stop completely. One way to stop bone bleeding is through the use of wax-like materials, which plug the bleeding bone and act as a physical barrier to stop bleeding. One example is Ostene bone hemostasis material, which has the advantage of being "water soluble", meaning it will dissolve naturally over time. The purpose of this study is to evaluate how well Ostene does at decreasing bleeding, by using a recognized scale called the validated intraoperative bleeding severity scale, abbreviated as "VIBe". In this study, the investigators will record the bleeding severity throughout multiple time points in surgery using this scale, and then the investigators will compare the measurements to patients in the past who did not receive Ostene. Overall, this research will help measure how well Ostene decreases bleeding.
Subarachnoid hemorrhage (SAH) is a common and extremely critical disease in neurosurgery. The mortality rate within 30 days of the onset of SAH is as high as 50%, and about 15% of SAH patients die without reaching the hospital. Nearly half of the survivors have severe neurological dysfunction, causing a huge burden to the families and society of the patients. Recently, the introduction of the "glymphatic-meningeal lymphatic vessels" drainage system has updated the current concept of intracranial cerebrospinal fluid circulation. After subarachnoid hemorrhage, a large number of blood components flooded into the subarachnoid space and entered the cerebrospinal fluid circulation, which directly affected the function of the lymphatic-meningeal lymphatic drainage system. Many preclinical animal studies have pointed out that the damage of the lymphatic-meningeal lymphatic drainage system is involved in the aggravation of cerebral edema, neuroinflammation and hydrocephalus after SAH, which ultimately leads to poor prognosis of patients. However, at present, the changes of the glymphatic-meningeal lymphatic drainage system after SAH have only been confirmed in animal models, and clinical evidence is lacking. With the development of imaging technology, many research teams have confirmed the functional changes of the lymphatic-meningeal lymphatic drainage system in Alzheimer's disease and Parkinson's disease by using different sequences of non-invasive MRI, such as 3D T2-FLAIR, DTI-ALPS and other sequences.
This study is researching experimental drugs called REGN9933 and REGN7508 (called "study drugs") and comparing their effects to approved treatments of rivaroxaban and aspirin (called "standard treatments"). Aspirin will be given alone or in combination with the study drugs or the other standard treatments to look at their effects on blood loss in the intestines. The aim of the study is to see if aspirin alone or the study drugs REGN9933 and REGN7508, when taken with aspirin, cause less minor intestinal bleeding than standard treatments rivaroxaban with aspirin. The study is looking at several other research questions, including: - What side effects may happen from taking the study drug - How much study drug is in the blood at different times - Whether the body makes antibodies against the study drug (which could make the drug less effective or could lead to side effects)
The goal of this observational study is to learn about quality of life, stress and caregiver burden in patients with stroke and their caregivers. The main question is: • to discover the factors associated with quality of life and stress in patient-caregiver dyads. Participants will be asked to fill out questionnaires and agree to provide a hair sample (in order to measure stress hormones in hair) and consent to use of their routine clinical and laboratory data. Researchers will compare a group of participants without stroke to establish a comparable baseline.
The purpose of the study is to see that in addition to existing therapy, how well an additional procedure named spinal cord stimulation might reduce blood vessel spasm from aneurysm rupture.
The purpose and aim of this study are to compare changes in pulse volume to non-invasively predict active bleeding or high-risk stigmata in patients undergoing a gastrointestinal endoscopy to assess feasibility of the flow meter clinically.
Patients with colorectal cancer (CRC) have a higher risk of both venous thromboembolism (VTE) and major bleeding (MB). Patients with CRC are underrepresented in the major trials examining treatment of cancer-associated VTE with anticoagulant.
The present study is a randomized, parallel control, and double-blind trial designed to assess the efficacy of baricitinib in reducing the occurrence of pulmonary complications in patients with spontaneous subarachnoid hemorrhage (SAH). The research protocol incorporates an adaptive design, allowing for modifications to key elements such as the sample size enrolled during interim analysis.
