Filter by: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.
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.
Post-discharge rehabilitation regimens for covid-19 patients have not been supported by high-quality evidence-based medical evidence.The first part of this study is a cross-sectional study.The contents of the study were the factors related to the dysfunction of COVID - 19 patients after discharge from the hospital in Wuhan.The second part of this study is a cohort study.To observe the functional changes of COVID-19 patients after discharge in hospital rehabilitation, home rehabilitation and no rehabilitation, in order to propose a more safe and effective rehabilitation program.
Psoriatic arthritis (PsA) is a chronic inflammatory rheumatic disease, belonging to the wide spectrum of spondyloarthritis, but with the particularity to be associated with personal psoriasis or familial psoriasis. PsA can be a very disabling disease through progressive and irreversible joint damage. Long-term functional prognosis of patients with PsA is correlated with the presence and severity of the radiographic joint lesions of the disease. However, the proportion of patients who will develop those peripheral joint damages is not yet known and less over the factors which are associated/involved in such an aggressive pattern of the disease. Early identification of this subgroup of patients is particularly important for determining early "intensive" treatment, strict management with a Treat To Target approach, and identification of new treatments with a stronger structural effect. The main objective of this prospective 10 years cohort is to describe the 5 years structural (radiographic) severity of recent PsA with recent peripheral arthritis.Some of the secondary objectives are to describe the 10 years structural severity within those patients, and to determine the predictive factors of those 5 and 10 years radiographic lesions (genetic, environmental, clinic, therapeutic factors). APACHE will provide a unique longitudinal standardized database concerning patients with PsA with very recent peripheral arthritis. Research projects which will based on those collected data should allow to identify the mechanisms of aggressive joint damage, to highlight mew treatments targets, to better describe the burden of the disease, to test previous or develop new assessments tolls, to develop early diagnostic criteria
