Active clinical trials for "Hemorrhage"

To evaluate the feasibility of Emergency Medical System (EMS)-performed cPOCUS in the field for diagnosis of acute Intracerebral hemorrhage (ICH)

Very preterm infants are prone to numerous medical complications with lifelong impact. Amongst the most serious are severe intraventricular hemorrhage (sIVH) and the subsequent progression to posthemorrhagic hydrocephalus (PHH). Currently, the only treatment for PHH is surgery, most commonly with shunts that are prone to malfunction across the lifespan. Preclinical data show that melatonin (MLT) and erythropoietin (EPO), when administered in a sustained dosing regimen, can prevent the hallmarks of progression from early postnatal sIVH to subsequent PHH. The investigators will perform a Phase I, single institution, randomized, double-blind trial for very preterm infants with sIVH to define a safe combination dose of MLT and EPO. A maximum of 60 very preterm neonates with sIVH will be enrolled, treated through 33w6/7d, and followed to 37w6/7d. Neonates will be randomized 3:1 between MLT+EPO and placebo, with all receiving standard of care. The primary endpoint is a composite serious adverse event (SAE)/dose limiting toxicity (DLT). The investigators hypothesize that the MLT+EPO SAE/DLT rate will not be higher than the placebo rate. Secondary outcomes will be rate of co-morbidities of preterm birth. Exploratory data, collected to guide design of future clinical trials for efficacy, will include serial neuro-imaging metrics acquired from clinical images, serial neonatal neurodevelopmental examinations, serum and urine MLT and EPO levels, and liquid biomarkers. Successful implementation of this initial safety trial will provide essential data to guide the next stage of clinical trials to test if sustained MLT+EPO treatment can reduce the need for surgical intervention, and avoid the lifelong burden of shunted hydrocephalus.

Rationale: Preterm neonates with low platelet counts receive prophylactic platelet transfusions with the aim to prevent bleeding. However, it is not clear in which cases platelet transfusions reduce the risk of bleeding or whether they do more harm than good. A large, randomized trial showed that the higher platelet count threshold for transfusion was associated with a higher rate of death and major bleeding, which suggests that platelet transfusions caused harm in neonates. To gain insight into the risk/benefits of platelet transfusions, the investigators will validate a recently developed dynamic prediction model for major bleeding in multiple NICUs in Europe and investigate the effects of prophylactic platelet transfusions on the risks of bleeding and potential transfusion-associated adverse events. This model could then be used in future studies to define enhanced indications for transfusion, with the ultimate goal to prevent transfusion-associated harm in this vulnerable population. Objectives: Validation of the existing dynamic prediction model in an international cohort of preterm neonates with severe thrombocytopenia (platelet count <50x10^9/L) admitted to a NICU. Model amendment to enable prediction of bleeding risks under various hypothetical platelet transfusion strategies in preterm neonates with severe thrombocytopenia. To examine whether prophylactic platelet transfusions are causally associated with the occurrence of bronchopulmonary dysplasia (BPD), necrotizing enterocolitis (NEC), proven sepsis, retinopathy of prematurity (ROP), major bleeding, and mortality. Study design: Multicenter international retrospective cohort study. Study population: Neonates with a gestational age <34 weeks and a platelet count <50x10^9/L, admitted to a NICU between January 1st 2017 and January 1st 2022. Main study endpoints: Major bleeding, BPD, NEC, proven sepsis, ROP and mortality. Nature and extent of the burden and risks associated with participation, benefit, and group relatedness: Not applicable, as this is a retrospective study.

This is a post market prospective, single arm clinical investigation to continuously assess the safety performance and effectiveness of the Celox™ PPH as a uterine haemostatic tamponade treatment for uterine postpartum hemorrhage (PPH).

Endoscopy is important for the diagnosis and treatment of acute upper gastrointestinal bleeding (AUGIB), especially acute variceal bleeding (AVB), in patients with liver cirrhosis. However, the optimal timing of endoscopy remains controversial, primarily because the currently available evidence is of poor quality, and the definition of early endoscopy is also very heterogeneous among studies. Herein, a multicenter randomized controlled trial (RCT) is performed to explore the impact of timing of endoscopy on the outcomes of cirrhotic patients with AVB.

The purpose of the present study is to study the effect of baricitinib administration on outcome of participants with moderate and severe traumatic intracerebral hemorrhage/contusions. A multi-center randomized control trial will be conducted. Participants with a radiological diagnosis of traumatic intracerebral hemorrhage/contusions and an initial GCS score of 5-12 will be screened and enrolled in the first 24 hours after traumatic brain injury.

This study aims to find out if there are common major changes in coagulation immediately after delivery of the newborn during Cesarean (C) -section and vaginal birth.

This is an observational retrospective database study of hospitalized patients treated with andexanet alfa in approximately 10 Dutch hospitals. Currently there is limited information on the patient characteristics and outcomes of patients who are treated with andexanet alfa in The Netherlands and how it is used. This is of interest for treating clinicians because there is a need for a patient profile, also due to the on par position of andexanet alfa with PCC in the Dutch national guideline.

The SPARTA study is a prospective multicenter observational trial in the Netherlands with the aim of identifying the best clinical care in patients with aneurysmal subarachnoidal haemorrhage. Differences in outcome between surgical treatment and endovascular treatment will be explored. Furthermore, cost effectiveness and radiological prognostic factors will be examined.

Critically ill children supported by extracorporeal membrane oxygenation (ECMO) receive large volumes of prophylactic platelet transfusions to prevent bleeding. However, mounting evidence has demonstrated significant morbidity and mortality associated with these transfusions. The ECmo hemoSTAtic Transfusions In Children (ECSTATIC) pilot trial will test two different platelet transfusion strategies, based on two different platelet counts thresholds, one high (higher platelet transfusion strategy) and one low (lower platelet transfusion strategy). The pilot will gather the necessary information to perform a full trial which will provide a better understanding of how to transfuse platelets to children supported by ECMO and reduce the associated morbidity.
