Filter by:The goal of this observational study is to learn if acutely and/or chronically altered sleep induces inflammation and/or a pro-thrombotic state (a tendency to form clots) in hospital workers who either work in shifts or are exclusively daily workers. The main questions it aims to answer are: - Does chronically altered sleep induce a pro-inflammatory and pro-thrombotic state, which are steps towards cardiovascular disease, knowing that is associated with poor sleep? - Does acutely disrupted sleep, such as that observed in night shift workers, induce a pro-inflammatory and pro-thrombotic state in otherwise healthy subjects? Participants in the study are hospital workers who either work in shifts, including night shifts, or only during the day. Sleep quality is assessed by a validated questionnaire (the Pittsburgh Sleep Quality Index). Markers of inflammation and of the pro-thrombotic state are measured at baseline and, if appropriate, after the night shift. These are markers of platelet activation, D-dimer, Interleukin-6 and endothelin 1, known to contribute and/or to suggest a condition of generalized inflammation and a tendency to form clots. Relevant information on health status is also collected for each participant.
Peroral endoscopic myotomy (POEM) is a novel endoscopic technique for the treatment of achalasia and other esophageal motility disorders. Initially, it was introduced to the world by Inoue et al. in 2008.7 Thereafter; it was rapidly disseminated because of low invasiveness, higher efficacy and technical novelty. The steps of performing POEM include mucosal incision, submucosal tunnel creation, myotomy and closure of the incision. Mucosotomy (2.8%) is the most common adverse event in patients undergoing POEM.8 It can be due to excessive use of cautery because bleeding points could not be seen clearly with white light during active ooze. RDI will help in early recognition of the bleeding points, thus prompt hemostasis. Bleeding during POEM is not very uncommon(0.5-0.7%).9 Early recognition of bleeding points and quicker hemosasis help in decreasing complications. The utility of RDI in the peroral endoscopic myotomy is not studied so far to our knowledge. Hence in this study we would like to look into the utility of red dichromatic imaging in per-oral endoscopic myotomy.
Coagulopathy, bleeding, and transfusion are common in cardiac surgical patients. Our collaborator has developed a novel point of care device that can be used to assess thrombin generation in real-time in cardiac surgical patients. The investigators will measure thrombin generation using our novel device and compare it to standard methods, while examining the association of thrombin parameters with bleeding and other clinical outcomes.
The G-NUH registry is a two-center, real-world registry of percutaneous coronary intervention in patients with significant coronary artery disease. From January 2010, PCI-treated patients from Gyeonsang National University Hospitals (Jinju & Changwon) were enrolled in this registry. The aim of this registry is to investigate long-term clinical outcomes and predictors of adverse outcomes after percutaneous coronary intervention from the academic hospitals.
This is a 3-phase mixed methods study design. A literature review (Phase 1) has been completed to determine the areas of exploration and to identify challenges faced and the impact of the blood disorder on pediatric patients. Based on Phase 1, Phases 2 and 3, as proposed in this study, will be completed and will include interviews of patients diagnosed with bleeding and thrombotic disorders (phase 2). The interviews will be individual, semi-structured, and consist of open-ended questions to elicit unbiased and in-depth responses to gain an understanding of participant's perspectives on themes predetermined in the study design phase.
Ineffective hemostasis or a paradoxical prothrombotic state of Acute-on-chronic liver disease (ACLF) has been well established. However, the minor and major bleeding events has not been described yet. We observe the patients' major and minor bleeding events and use 4 criteria, which include BARC, ISTH, TIMI, Gusto ,to evaluate the incident rate of bleeding events in ACLF patients and pre-ACLF patients.
