Filter by:The aim of this study is to increase the effectiveness of clinical monitoring of patients with acute cerebral insufficiency by improving the discriminative ability of the FOUR scale. To study the sensitivity and specificity of the FOUR scale as a clinimetric of chronic disorders of consciousness.
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: 1. 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. 2. Model amendment to enable prediction of bleeding risks under various hypothetical platelet transfusion strategies in preterm neonates with severe thrombocytopenia. 3. 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.
INTRODUCTION Knee supports, usually made with sponge cushion, are used to protect knee joint and prevent its injury. Sponge has less elasticity and durability compared with natural rubber. To our knowledge, there has been no study regarding effectiveness of natural rubber and sponge for knee joint protection and injury prevention in children with bleeding disorders. AIMS The study aimed to compare the effectiveness and satisfaction between natural rubber and sponge knee supports for knee joint protection among children with bleeding disorders METHODS The study had three phases: 1) measurement of compression force, 2) fabrication of knee supports, and 3) a randomized crossover trial. The supports were fabricated in 4 sizes, S, M, L, and XL. They comprised two parts: body, made from stretchable cotton; and cushion (protection part), made from either natural rubber or sponge. The trial included 8 weeks of alternatively wearing natural rubber knee support and sponge knee support with a 4-week wash-out period. Numbers of knee bleeds and satisfied users were recorded.
Enhanced recovery after bariatric surgery imposes a significant reduction in length of hospital stay. However beneficial for the overall recovery it reduces the hospital observation time. after a laparoscopic surgery during which one of the longest resection line in surgery or anastomosis are created. Therefore, discovering possible safe and effective ways of pharmacologically reducing surgical blood loss and reducing the risk of postoperative bleeding would be an invaluable addition to the protocol. The systemic use of tranexamic acid (TXA) has been shown to be effective in many types of surgery, reducing the incidence of post-operative bleeding and thereby reducing the rate of reoperation.
1. The primary aim of this study is to investigate the correlation between the length of ICU stay and a newly developed FIVE score in neuro-intensive care patients. 2. The secondary objectives are to evaluate the impact of the FIVE score on hospital length of stay, Modified Rankin Scale, and mortality, as well as to determine the correlation between the GCS, FOUR, and FIVE scores
The primary goal of the present prospective cohort study is to evaluate the effect of varying incidences of BOP at implant sites across 15 months of maintenance visits on the probability of peri-implant disease progression. Over 15 months, participants will attend 6 visits where clinical measurements and maintenance care will be performed every 3 months.
An MRI study to examine the relationship between blood pressure and cerebral blood flow in patients with subarachnoidal hemorrhage and suspect or verified vasospasm.
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).
The goal of this observational study is to use artificial intelligence to differentiate cerebral hemorrhage from contrast agent extravasation after mechanical revascularization in ischemic stroke. The main question it aims to answer is: Whether artificial intelligence can help differentiate brain hemorrhage from contrast agent extravasation. Patients with intracranial high-density lesions on CT scans within 24h after mechanical revascularization will be included. Expected to enroll 500 patients. The type of high-density lesion is determined according to dual-energy CT images or follow-up images. Patients will be divided into training group, validation and testing groups by stratified random sampling (6:2:2). After the images and the image labels are obtained, deep learning artificial intelligence will be used to learn the image characteristics and establish a diagnostic model, and the model performance and generalization ability will be evaluated.
The goal of this clinical trial is to examine the effect of limb occlusion therapy (remote ischemic conditioning, RIC) in subjects with aneurysmal subarachnoid hemorrhage. The main question it aims to answer is whether RIC can improve long-term recovery in participants with aneurysmal subarachnoid hemorrhage. Researchers will compare levels of functional independence in participants in the RIC-group to participants in the sham-group.
