Filter by:The goal of this observational cohort study is to learn about the etiology, natural course, therapeutic effect and outcome of recurrent acute pancreatitis patients. The main question it aims to answer is: Does endoscopic intervention, surgery or conservative treatment reduce the recurrence of acute pancreatitis? What are the risk factors affecting the recurrence of acute pancreatitis? Patients will be closely followed and clinical information will be recorded.
The goal of this observational study is to explore the different immunosuppressive agents and related outcomes in organ transplantation patients in Taiwan. The main question it aims to answer is the risk of different immunosuppressive agents for infection and survival after transplant. The study enrolled patients who underwent solid organ transplant (SOT), kidney (ICD-9-CM code V42.0), liver (ICD-9-CM code V42.7), or lung (ICD-9-CM code V42.6) transplants. We employed propensity score matching (PSM) to establish a matched cohort. The study will compare SOT patients and general patients to explore the risk of different immunosuppressive agents for infection and survival.
The bi-directional dynamic cohort study is to learn about the effects of prenatal exposure to high blood glucose levels and postnatal nurturing environment factors on delayed language development in children. The study investigated the results of blood glucose screening during pregnancy for the children's mothers, and followed up on the blood glucose management effectiveness of pregnant women with abnormal blood glucose levels before delivery. Participants will be also surveyed the "S-S method for language development assessment, "gsell Scale", and "0-6 year-old family nurturing environment evaluation scale" to evaluate the language development and family nurturing environment.
Chronic Rhinosinusitis (CRS) is a common and frequent disease in otorhinolaryngology. The main symptoms of patients include nasal congestion, runny nose, swelling pain of the frontal area and decreased sense of smell. Chronic rhinosinusitis refers to chronic rhinosinusitis with symptoms lasting ≥12 weeks and can be divided into two subgroups: chronic rhinosinusitis with and without nasal polyps. Chronic rhinosinusitis has a complex pathogenesis, there are three main pathogenic factors: infection, allergy and nasal and sinus anatomic abnormalities, these factors are often not a single existence, but often intertwined. In addition, environmental factors, genetic factors, osteitis, gastroesophageal reflux disease, respiratory ciliary system defects, systemic immune dysfunction and other secondary risk factors. For patients with chronic sinusitis, these symptoms, such as nasal congestion, runny nose, swelling pain and decreased sense of smell, often seriously affect their quality of life, and even evolve into more serious complications as the disease progresses. At present, the conventional treatment methods mainly include drug conservative treatment and nasal endoscopic surgery. Functional nasal endoscopic sinus surgery (FESS) is the main method of further surgical treatment for patients with no obvious effect of drug treatment. In FESS, the current emphasis is on removing diseased tissue and restoring sinus drainage on the premise of preserving the normal mucosa and physiological structure of the nasal and nasal sinuses as much as possible. Up to now, there have been many studies on surgical treatment of CRS, and the quality of the studies varies. However, in view of the postoperative efficacy and long-term prognosis of different subtypes of CRS, different treatment methods during surgery and different drug therapy regimens, our research group believes that it is necessary to accumulate a large amount of clinical data support through in-depth research and comprehensive analysis. Thus more reliable conclusions can be drawn. In this study, patients undergoing CRS surgery in the research ward of the Department of rhinosinusitis will be actively included through a prospective single-center cohort study to provide evidence for evidence-based medicine and better guide clinical rhinologists to make surgical treatment decisions for patients with chronic rhinosinusitis.
Thirty years ago, Dzau and Braunwald introduced the concept of a continuum of cardiovascular diseases and defined them as a series of events caused by numerous related and unrelated risk factors, thus developing to end-stage heart disease through many pathophysiological pathways and processes. Owing to treatment concept changes and the urgency of investigating T2D combined with CHF, SUs are being re-evaluated, of which glimepiride is undoubtedly the most promising.
Based on the previous study of NCT04651738, we performed this trial to further confirm the accuracy of host DNA CDO1 and CELF4 methylation for endometrial cancer screening in a multi-center cohort. Thirteen hospitals, including Peking Union Medical College Hospital, would enroll eligible patients in this study. The cervical cytology of 3 ml will be collected for the detection of DNA CDO1 and CELF4 methylation, and the results will compared with the endometrial histological pathology, which is achieved after collection of cervical cytology, by surgeries including hysteroscopy, dilation and curettage, total hysterectomy and others. The methylation testing would be double-blinded in operators and analysts. The study will enroll at least 10,000 patients.
The cohort study on disease prevention and health promotion in the northeastern region of Taiwan is a trial dedicated to large-scale generational research in northeastern Taiwan beginning in the August of 2013. The program aims to develop a comprehensive and integrated approach to disease prevention and community health. The researcher's cohort organizes healthcare outreaches for participants over the age of 20 residing in 64 administrative areas in Keelung city and new Taipei city. The researcher's sessions include a comprehensive health examination, health-related questionnaires, and disease awareness seminars. Biological samples, questionnaire information, and medical data obtained from researcher's participants are stored in researcher's core laboratory. Depersonalized data and samples are shared with partnering trials approved by the Chang Gung Memorial Hospital Institutional review board. The investigators are currently partnered with 18 clinical trials spanning across multiple disciplines such as urology, hepatology, metabolism, physical therapy, and psychology.
This study is an evaluation of the flexible and integrative psychiatric care model (according to § 64b of the German Social Code Book V (SGB V)) (FIT64b) in the child and adolescent psychiatry at the University Hospital Tübingen (UKT). The central concern of this evaluation is to answer the question whether FIT64b models offer advantages over standard care. The orientation of model care is a more cross-sectoral provision of services through more flexible treatment intensities.
Since the 2000s, many prognostic scores were developed to predict traumatic haemorrhage. Most of these studies were retrospectives based on registers. Due to missing data on death due to bleeding, these studies chose to predict the massive transfusion risk as a surrogate of haemorrhagic death. These scores include clinical parameters (vital signs), laboratory values (Haemoglobin, lactate, Base excess) and/or imaging (CT or ultrasound) values. The scores showing best performance are the Trauma Associated Severe Haemorrhage (TASH) score, developed and validated on the German register (DGU-Register) and the ABC score developed and validated in the United States of America. However, the majority of these scores cannot be applied at the trauma scene due to the unavailability of laboratory and imaging values. Therefore, their clinical utility remains unclear. To overcome the need for diagnostic tests, authors have developed and recently validated a clinical prognostic score in identifying trauma patients with, or at risk of, significant haemorrhage based on predicted probabilities of death due to bleeding: BATT score. This score was developed from an international cohort using data from 271 Trauma Centres in 41 countries on 5 continents and uses first clinical parameters at initial assessment. The BATT score predicts death due to bleeding and has been validated on a large population in England and Wales. It could also predict massive transfusion, as a surrogate of haemorrhagic death, earlier at the trauma scene. Its feasibility and external validation would make its clinical utility superior to other scores while identifying a greater number of patients requiring early management. Our study is an external validation of pre-existing prognostic scores of traumatic haemorrhages (TASH , ABC and BATT score) at different times of care (Scene of Injury, admission at the trauma room) in order to assess their overall performance, discrimination and calibration in the prediction of massive transfusion, and haemorrhagic death. The objective of the study is to assess a comparison of score performances (Overall performance, discrimination and calibration). Due to the study population (STR), which is partly integrated into the German DGU-Register, the investigators expect good transportability of the TASH score to the Swiss Trauma Registry in terms of overall performance, discrimination and calibration. The ABC score should show lowers results in terms of discrimination due to its validation on small cohorts exclusively in North America. The new BATT score predicting death due to bleeding has been validated on a large English cohort of more than 100,000 patients. It identifies all patients with haemorrhage and not only patients who have received a massive transfusion subject to survival bias. In this context, the BATT score provides good discrimination with only simple physiological variables available at the trauma scene. In case of its external validation on the STR as part of our study, its feasibility would make its clinical utility superior to other pre-existing scores, while identifying a greater number of patients requiring early management. Its application would activate a massive transfusion plan directly at the trauma scene and save precious time.
