Active clinical trials for "Hemorrhage"

The main objective of this study is to research the treatment of 35 kDa hyaluronan fragment HA35 for Mild periodontitis and associated with gingival discomfort or itchiness.

The goal of this study is to assess the physician and patient experience of radio frequency (RF) track cautery in patients undergoing needle biopsy of the liver, kidney, or spleen who have one or more risk factors for biopsy-related bleeding. RF track cautery involves inserting a bipolar electrode through the same introducer needle used for the biopsy, and heating the tissues along the path of the biopsy needle to prevent bleeding. This study primarily aims to assess the operator and patient experience during the use of track cautery. Secondary aims are to assess the technical success rate and procedure adverse events. Participants who enroll in the study will undergo track cautery as part of their clinically indicated liver, kidney, or spleen biopsy. After the procedure, they will fill out a brief survey asking about their experience during the procedure. Physician operators who perform track cautery as part of the study will also fill out a survey after each procedure asking about their experience using this technique.

Compared to the United Kingdom and the United States, Spontaneous non-traumatic intracerebral hemorrhage (ICH) is more common among people in Taiwan. The prevalence rate of ICH was 14.0% for people aged 36 years or older in Taiwan. Primary ICH originates from the spontaneous rupture of small vessels damaged by chronic hypertension or cerebral amyloid angiopathy (CAA). Emotional disturbances are frequent symptoms in stroke survivors and negatively impact on functional recovery, the patient's quality of life and are distressing for both the patients and their caregivers. Furthermore, the emotional disturbances are associated with impaired cognitive. However, these issues are often unnoticed and most of the studies had been performed in ischemic stroke survivors rather than in patients with ICH. In this study, we will be recruited participants from National Taiwan University Hospital Bei-Hu branch and National Taiwan University Hospital. We aim to enroll respectively maximum number of 60 patients who had previous spontaneous ICH. Each participant will receive neuropsychiatric assessment, cognitive screening tests, domain-specific cognitive tests, a questionnaire for their quality of life and blood drawing for ApoE genotyping. The main aims of this study include (1) To investigate the prevalence of distinct neuropsychiatric symptoms in ICH survivors (2) To investigate the impact of non-cognitive neuropsychiatric issues on the cognitive functions and quality of life in ICH survivors. Our results may remind clinicians to pay more attention to the early diagnosis and effective management of neuropsychiatric symptoms to improve clinical outcomes.

The goal of this multicenter prospective observational study and registry of U.S. adolescents and young adults with heritable bleeding disorders is to determine the bleeding outcomes, satisfaction, hemostatic parameter changes, and patient reported quality of life after 6 months of use of either of two commonly used hormonal treatments for menstrual suppression - levonorgestrel intrauterine device (LNG-IUD) and norethindrone acetate (NETA). Under this application we will compare the two treatments and compare outcomes after LNG-IUD treatment results to a control group without a bleeding disorder, with the goal of determining the benefits and expected outcomes of these treatment options for this population.

Delayed cerebral ischemia (DCI) following aneurysmal subarachnoid hemorrhage (aSAH) results from a complex combination of macro- and microvascular processes. Besides cerebral vasospasms (CVS), DCI is caused by microthrombosis, neuroinflammation, microvascular dysfunction and cortical spreading depolarization.The glycocalyx plays an essential role in regulation of inflammation, oxidative stress and thrombosis, and could be involved in the pathophysiology of DCI. This study is a single-center prospective observational pilot (phase 1) and correlation (phase 2) study recruiting patients with an aneurysmal subarachnoid hemorrhage. The primary aim of the study is to evaluate the feasibility of performing measurements of the glycocalyx using side-stream darkfield (SDF) imaging sublingually and on the conjunctiva, and by sampling blood for analysis of markers of glycocalyx shedding. Moreover, the objective is to determine characteristic Doppler waveform morphologies in DCI patients by means of thorough analysis of transcranial Doppler (TCD) measurements. The secondary objective is to determine whether changes in glycocalyx integrity correlate with the development of DCI and whether these changes are associated with increased inflammation and with variation in TCD signals. Finally, changes in glycocalyx integrity, in TCD waveform morphology and in levels of inflammatory markers will be correlated with patient outcome at 6 weeks and 6 months after ictus.

In the present study, we test the ability of AMSS as a simple tool to identify women with HMB who have ID/ IDA. We will compare the AMSS score to patients' hemoglobin and serum ferritin in women with self-reported HMB and women with normal menstrual flow.

Postpartum hemorrhage is the leading cause of maternal morbidity and mortality throughout the world. Rapid diagnosis and early management improve maternal prognosis. Postpartum hemorrhage is defined by a blood loss exceeding 500 ml during the 24 h after delivery. There are many causes of postpartum hemorrhage. Most cases develop from uterine atony, which accounts for 75% of cases. Even though there are risk factors for postpartum hemorrhage, it is still an unpredictable obstetric emergency. Coagulation plays an important role in postpartum hemostasis. Primary and especially secondary coagulation disorders are risk factors for Postpartum hemorrhage. When bleeding occurs, the decrease in fibrinogen levels is the most rapid change observed among markers of coagulation. Recent studies show that fibrinogen concentration during the initial management of Postpartum hemorrhage is the most informative biological marker for the severity of the hemorrhage. Various methods are used to record coagulation profile. One of them is estimation by sonoclot. Viscoelastic hemostatic assays devices (such as sonoclot) have practical advantages as point-of-care devices for monitoring major hemorrhage including a set of parameters that assesses a global coagulation profile like fibrinogen and platelet count. Identification of coagulopathy by viscoelastic point-of-care testing can be helpful in guiding management of Postpartum hemorrhage and preventing severe maternal outcomes.

This is a single-center, double-blind, randomized controlled trial (RCT) comparing two groups of application of topical dose of tranexamic acid (TxA) versus placebo in patients undergoing coronary artery bypass graft (CABG), off pump coronary bypass graft cardiac surgery (OPCAB), and adult heart valve surgery. The primary outcomes of this study comprised of two parameters; post operative bleeding and blood product transfusion. The primary outcomes were assessed during the operation, until 48-hour post operative.

The goal of this clinical trial is to test if the study drug, BXP154 works to stop bleeding from a minor wound in patients that are on anticoagulant therapy. The main questions it aims to answer are: How long does it take to stop bleeding after BXP154 is applied to a wound? How many people require the use of a rescue treatment to stop bleeding? Does BXP154 reduce instances of re-bleeding after the bleeding has stopped initially? Is BXP154 safe and well-tolerated?

This trial compares the haemostatic effect of viscoelastic haemostatic assay (VHA)-guided transfusion strategy versus non-VHA guided transfusion strategy in haemorrhaging trauma patients. Half of the randomised patients will receive VHA-led management of bleeding, whilst the other half will receive massive transfusion protocol resuscitation using conventional coagulation tests.
