Filter by:Study objective: To establish a quality control system for gastrointestinal endoscopy based on artificial intelligence technology and an auxiliary diagnosis system that can perform lesion identification, improving the detection rate of early gastrointestinal cancer while standardizing, normalizing, and homogenizing the endoscopic treatment in primary hospitals (including some of the primary hospitals, which are participating in Beijing-Tianjin-Hebei Gastrointestinal Endoscopy Medical Consortium) under Gastrointestinal Endoscopy Artificial Intelligence Cloud Platform as the hardware base. Study design: This study is a prospective, multi-center, real-world study.
Recent studies showed that the value of c100A12 increased in children with Kawasaki disease, and decreased rapidly after treatment with gamma globulin. In kawasaki disease with coronary artery dilatation, S100A12 levels are elevated in the acute phase of Kawasaki disease and continue for some time in the convalescence phase before gradually decreasing. However, the number of patients included in previous studies was small and the follow-up time was short. In this study, 100 children with Kawasaki disease who were admitted to Wuhan Children's Hospital, Jingzhou First People's Hospital and Renhe Hospital affiliated to China Three Gorges University from December 2021 to December 2023 were selected as the research objects, and 100 children with healthy physical examination were selected as the control group during the same period. To investigate whether S100A12 increased significantly in the acute phase of Kawasaki disease compared with a healthy control group. To study whether S100A12 value increased rather than decreased in kawasaki disease that did not respond to gamma globulin treatment after gamma globulin treatment. At the same time, to study whether the increase of S100A12 in kawasaki disease convalescence indicates coronary aneurysm.
Colonoscopy completion by caecal intubation seldom represents a significant effort for the endoscopist. In this situation, additional techniques are necessary to achieve this goal: patients' manual abdominal compression, postural changes, and endoscopist relay. To date, no tool allows colonoscopy technical difficulty grading. This study pursues to describe the frequency of additional techniques for caecal intubation in a large sample of Argentinians in different centres who undergo colonoscopy for attending purposes, to develop a novel score for assessing colonoscopy technical difficulty.
Decontextualised risk information is any information pertaining to diagnosis, which is introduced into a clinical consultation, or a diagnostic thought process, without being requested by the clinician. It can be risk scores, computerised warnings, or lab tests or diagnostic imaging requests ordered by other clinicians. It is a concept which (to our knowledge) has not been studied. Clinical vignettes have been developed to simulate scenarios where decontextualised risk is introduced into a consultation. These will be presented to primary care clinicians via video, who will then undergo a structured interview to explore how their perception, processing and communication of risk is challenged and changed by decontextualised risk. The findings will be analysed used qualitative methods (Thematic Analysis).
10 to 35% of patients admitted to an emergency department receive an incorrect diagnosis. Not surprisingly, given the wide variety of health conditions encountered in emergency medicine, physicians often do not consider, remember, or know all possible diagnoses that fit the patient's symptoms. Nowadays, computer software (CDDS) is able to support physicians with a list of possible diagnoses by matching entered patient data to a large database with diagnoses. However, it is still unclear how the use of such a CDDS actually affects the diagnostic quality and workflow in 'real world' ER routine care. Therefore, the aim of this cluster-randomized cross-over trial is to evaluate the consequences of CDDS usage on diagnostic quality, patient outcomes and diagnostic workflow within the ER. Four ER's will provide a CDDS to the diagnosing physicians for specific periods (randomly and alternatingly allocated) in which physicians will be asked to use it for all included study patients. Outcomes between periods with and without the CDDS will be compared. Primary outcome is a diagnostic quality risk score composed of unscheduled ER revisits, unexpected hospitalization (both within 14 days), unexpected intensive medical care unit admission if hospitalized and diagnostic discrepancy between the ER discharge diagnosis and the current diagnosis after 14 days. In total, 1'184 patients will be included.
Proximal femur fractures (PFF) are a worldwide public health concern. A delay in the diagnosis and treatment worsens the prognosis. Inversion of grayscale is a tool available on most X-rays visualization software, and its use has been suggested to improve radiological diagnosis. The study aims to determine if using inverted grayscale radiography results in better diagnoses of PFF among medical students. Material and Methods. The investigators evaluated the detection of PFF by fifth-year medical students on a series of 30 pelvis X-rays. The series was composed of 20 X-rays with PFF and 10 X-rays without fracture. A first reading session was set up where X-rays were presented separately in conventional and inverted grayscale. A second session one month later showed both grayscale visualizations together (BIcontrast X-rays Analysis Method - BIXAM). X-rays' order of appearance was randomized. The investigators performed the same evaluation on senior orthopedic surgeons as a control. Finally, sensitivity, specificity, and accuracy were assessed for each method (conventional, inverted, and BIXAM) with the McNemar test. Subgroup analyses were performed on the fracture localization (femoral neck, trochanteric).
The application of conventional endoscopy in remote and outdoor areas lacking facilities remains challenges. Thus, the investigators developed a novel portable upper gastrointestinal endoscopy system that has the same functions as conventional endoscopy. A total of 24 participants from a medical unit on a remote island in China underwent endoscopy with the portable system between March and June 2021. The portable system packed into a suitcase is 68 × 42 × 32 cm in size, weighing less than 35 kg, and comprises a disposable sheathed system.
Rationale: Acute intestinal ischemia is a life-threatening condition with a short-term mortality that can range up to 80%. Medical diagnosis and treatment have remained troublesome, due to the clinical presentation which is mostly characterized by non-specific signs and symptoms. Early unambiguous diagnosis of acute intestinal ischemia is critical to prevent progression from reversible to irreversible intestinal injury, and henceforth decrease morbidity and improve survival. Objective: We aim to validate a panel of plasma biomarkers and investigate volatile biomarkers that allow early and accurate identification of acute intestinal ischemia in patients. In addition, we aim to identify a volatile organic compound (VOC) profile specific for acute intestinal ischemia in exhaled breath. Study design: Prospective observational study Study population: All patients suspected of acute intestinal ischemia Main study parameters: The primary endpoint of the study is the early and accurate identification of presence and severity of acute intestinal ischemia in patients. The main study parameters are plasma biomarkers indicative for intestinal damage and volatile organic compounds (VOC) in exhaled air of patients suspected of acute intestinal ischemia. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: There is a minimal amount of risks involved in participating in this study. Blood samples will be obtained with the use of an arterial line, intravenous line (IV), central venous catheter (CVC), peripheral venous catheter (PVC) or a venepuncture. The risk of venepuncture is a small local hematoma. In addition to blood sampling, we will also obtain exhaled air. This non-invasive procedure takes approximately 5 minutes in which patients breath in a 3L Tedlar bag at a normal frequency and volume. This procedure will not cause any physical strain. Collection of samples and data will take place during the hospital stay of the included patients. For this reason, no additional hospital visits are required for this study. Participating patients in this study will have no direct benefits, but in the future the results of our study will likely be useful in the early diagnosis of patients suspected of acute intestinal ischemia. The research goal in this study is the early identification of patients that suffer from acute intestinal ischemia. These patients are difficult to diagnose due to a multitude of non-specific symptoms and the lack of fast and specific tests. In this study we will be able to investigate patients that are admitted with acute abdominal complications and observe them in the early stages of their condition. Accordingly, we will be able to evaluate the proposed panel of biomarkers and to identify VOC patterns in patients with acute abdominal complications.
This study is a population-based, patient-level analysis of colon and ovarian cancer diagnoses in England over a 2-year period using a dataset created by linking NCRAS and NHS digital datasets. Our analyses will look into inequalities in the diagnostic and treatment pathway, and inequalities in treatment received, for those diagnosed with colon and ovarian cancer between 2016-2017.
The objective of this project is to evaluate the capability of a specific mobile electrocardiogram monitoring of detecting arrhythmic events in children with history of palpitation and or syncope. We will compare this approach with the standard approach of clinical follow-up plus 24-hour Holter ECG monitoring in terms of acceptability and ability to identify significant arrhythmias.
