Filter by:Non-randomized study of robot-assisted perineal reconstruction with rectus abdominis muscle flap in patients operated with abdominoperineal resection for irradiated locally advanced rectal or anal cancer. Operative time, complications, wound healing, pre- and postoperatively abdominal wall strength and patient related outcomes including sexual health will be registered.
1. To establish the Chinese people's own clinical data database of colorectal cancer, reflecting the law and characteristics of colorectal cancer patients in China. 2. Based on colorectal cancer surgery, collect clinical data, especially data on clinical manifestations, complications, laboratory tests, auxiliary examinations, postoperative clinical effects, surgical complications, and colorectal cancer recurrence, so as to lead the direction of clinical practice and academic research of colorectal cancer surgery in China. It provides a certain basis for future research on colorectal cancer. 3. Provide academic consultation and data support to national health authorities.
Observational study in two medical-surgical intensive care units of the Clermont-Ferrand University Hospital to develop a composite score for prediction of 72h-extubation failure in patients at risk of extubation failure.
For the purpose of quality assurance, the Swedish Association for Otorhinolaryngology and Head and Neck surgery has developed several national registers concerning ear, nose and throat care. One of these is the National Tonsil Surgery Registry in Sweden (NTSRS). In NTSRS patients undergoing tonsil surgery for benign indications are included. Data regarding indication, surgical methods and techniques as well as patient reported outcomes measures are collected. The register is designed to facilitate description of clinical activities in a unit and help identify the need of clinical improvement programs. By compiling national data, the register can be used to describe clinical practice in a large national cohort.
Infectious disease is the single biggest cause of death worldwide. New infectious agents,such as the Severe Acute Respiratory Syndrome coronavirus and new strains of influenza continually emerge and require new investigations to understand pathogen biology and pathogenesis in the host. Witness the Influenza A pandemic. Concerns about new viruses and their impact on health and the economy are also increasing. Current alerts sent out by the Ministry of Health (about the novel coronavirus and the Avian influenza A virus) are but cases in point. These likely reflect advances in science, which have allowed novel pathogens to be identified. Because of its geography, Singapore is vulnerable to new pathogens through importation or the global travel of its citizens. Hence we must be ever ready to meet unexpected challenges anytime. On the administrative front, Singapore General Hospital has a Disease Outbreak Task-force which has in place many plans that can be activated should there be a large-scale epidemic. What is missing thus far is a program that will enable us to perform scientific studies in the setting of an epidemic. Hence in this study, we will, in collaboration with the Program in Emerging Infectious Diseases (EID) in Duke-National University of Singapore Postgraduate Medical School, attempt to (i) detect novel, previously undescribed pathogens; (ii) characterize viruses (not necessarily novel but emerging and re-emerging) that are raising concern or causing clusters or epidemics in the hospital and/or country; (iii) characterize immune responses to such viruses in healthcare workers as well as patients (those affected by these viruses and those exposed to the affected). The techniques that will be used will be those not routinely available in a hospital's service labs. Some patients will remain undiagnosable with the best available technology. Since new laboratory tools that can detect previously undiagnosed pathogens may become available in the future, the study also aims to archive specimens from patients whose illnesses remain undiagnosed.
