Filter by:This study has been added as a sub study to the Simulation Training for Emergency Department Imaging 2 study (ClinicalTrials.gov ID NCT05427838). The purpose of the study is to assess the impact of an Artificial Intelligence (AI) tool called qER 2.0 EU on the performance of readers, including general radiologists, emergency medicine clinicians, and radiographers, in interpreting non-contrast CT head scans. The study aims to evaluate the changes in accuracy, review time, and diagnostic confidence when using the AI tool. It also seeks to provide evidence on the diagnostic performance of the AI tool and its potential to improve efficiency and patient care in the context of the National Health Service (NHS). The study will use a dataset of 150 CT head scans, including both control cases and abnormal cases with specific abnormalities. The results of this study will inform larger follow-up studies in real-life Emergency Department (ED) settings.
The aim of this retrospective study is to investigate the relationship between factor XIII activity and the outcome of gastrointestinal bleedings. Since factor XIII is of great importance in haemostasis and plays a key role in stabilizing the fibrin clot, it can be assumed that a deficiency of factor XIII leads to an unfavorable course of gastrointestinal bleedings. Our hypothesis is that early detection of such a deficiency can prevent a more severe course and that substitution of factor XIII contributes to faster cessation of bleeding, improves patient outcome and reduces the number of red cell concentrates required.
Concerns about the necessity and risks of blood transfusions have led to the search for new noninvasive monitoring methods. Oxygen reserve index (ORI), one of them, is a dimensionless index ranging from 0.00 (no reserve) to 1.00 (maximum reserve) according to oxygenation reserve status, and it is also a non-invasive and continuous measurement parameter. Some studies have examined ORi as an indicator for early detection of hypoxemia. There are reports in the literature that ORi and Pa02 values measured noninvasively during surgery are early precursors for desaturation and hypoxia.Researces aimed to investigate the relationship between perioperative blood transfusions and ORI in vertebral stabilization surgeries performed by the same surgical team in our clinic.
Background Blood transfusions in pregnancy are usually urgent, unpredictable, and occur in otherwise healthy women. There is evidence of increasing rates of maternal red blood cell (RBC) transfusion around childbirth both in Europe and in US. Indeed, they are recorded in approximately 0.4-1.6% of all deliveries. Although obstetric patients use a small proportion of the blood supply overall (3-4%), however over the last years there has been a significant increase (about 30%) in the use of blood and blood products throughout pregnancy. Most available data relate to the peri-partum period, defined as those occurring from 48 hours before delivery onwards. Anemia in pregnancy is associated with increased maternal mortality and fetal intrauterine growth restriction (IUGR). The risk of these adverse effects is proportional to the severity of anemia; for instance, preterm birth and low birth weight rates are particularly high among women with a hemoglobin below 7 g/dL. The presence of anemia in at-term pregnant women is a rather frequent and unrecognized risk factor for peri-partum hemorrhage (PPH) transfusion. In a retrospective investigation, we have calculated that almost 20% of at-term pregnant women show iron deficiency anemia. It has been suggested that reduction of RBC transfusion in the context of PPH may decrease maternal mortality and, at the same time, reduce costs. Patient's Blood Management (PBM) is a well-known strategy based on 1) identification of anemia; 2) reduction of blood loss and 3) reduction of RBC transfusion. In several medical specialties, recommendations based on available evidence highlighted the concept that a restrictive RBC administration is safe and efficacious. Despite the fact that the WHO has recommended PBM early 2010, the majority of hospitals are in need of guidelines to apply PBM in daily practice. Rationale Anemia is a frequent and often unrecognized hallmark of at-term pregnancies. Systematic collection of data on transfusion practice during pregnancy and post-partum period are scarce. The application of PBM in obstetrics is expected to improve pregnancy outcome and optimize resources. Objectives Objectives of the present study are 1. To estimate: frequency of anemia in pregnancy and feto-maternal complications, distribution of haemorrhage aetiologies and transfusion indications. 2. To evaluate associations of these outcomes with gestational age, and transfusion dose.
Bleeding from the gastrointestinal tract can originate from the small bowel. Typically, upper and lower endoscopies are unable to identify the site of bleeding and patients need to undergo special endoscopies with longer cameras to examine the small bowel and find the bleeding site. One of the most commonly used scopes to investigate the first part of the small intestinal is called "push enteroscopy". This is an upper endoscopy that uses a pediatric colonoscope, which is longer. To date, it is unknown what percentage of small bowel can be observed with this technique. Hence, this study aimed to determine the extent of small bowel examined by push enteroscopy. Consecutive patients with suspected bleeding from the small intestine will undergo a push enteroscopy and the depth of the examination will be marked with metallic clips. Subsequently, patients will have a capsule endoscopy, which is a little camera that will take multiple pictures of the whole small intestine. The percentage of small bowel that the push enteroscopy examined will be determined by the percentage of small bowel corresponding to the location of the clips visualized on capsule endoscopy.
Cerebral swelling is a major complication following aneurysmal subarachnoid hemorrhage.This study is a retrospective cohort aimed to predict the extent of brain swelling. Cerebral venous assessment can identify the risk of brain swelling and improve surgical outcomes.
The purpose of this observational study was to compare perihematomal edema and short-term prognosis in patients with intracerebral hemorrhage carrying the APOE-ε3 and APOE-ε4 genes. The main questions it aims to answer are: - Exploring whether patients carrying the ApoE-ε4 gene have more perifocal perihematomal edema after intracerebral hemorrhage than patients with the ApoE-ε3 gene. - ApoEε4 gene has worse short-term prognosis than ApoEε3 gene in intracerebral hemorrhage patients. All the patients in this study received the same medications based on the guidelines for the management of hypertensive intracerebral hemorrhage.Some ICH patients were evaluated for Stereotactic minimally invasive surgery (sMIS) treatment by two experienced neurosurgeons.
In this project the investigators study the safety and efficacy of the pipeline embolization device with vantage technology in treatment of unruptured brain aneurysms
The RE-BLEED feasibility study aims to develop and test a real-time digital platform, whereby bleeding patients in-hospital can be identified and approached for their consent to participate in future research studies.
This is a randomized controlled trial, aiming to evaluate the effects of time window for umbilical cord clamping during cesarean section on the health outcomes of offspring hemoglobin，maternal blood loss，and children's growth and development. It will be conducted in Liuyang city and Huantai county of China, and the targeted sample size is 360 (180 in each site). All the eligible pregnant women will be randomly assigned to one of the four groups (three intervention groups and one control group), and their babies will be followed up to 18 months of age.
