This study is a prospective, multi-center and observational clinical study. Investigators would like to explore the optimal emergency endoscopy timing in cirrhosis patients with esophagogastric variceal bleeding (EGVB) by evaluating and comparing the efficacy and safety of emergency endoscopy performed at different times ( within 6 hours or between 6 and 24 hours after gastroenterologic consultation ) and its impact on the short-term prognosis.
The CASES-TCM study is a prospective, multicenter, observational study, which will enroll 20,000 patients with acute stroke (ischemic stroke or intracerebral hemorrhage) within 7 days of symptom onset. This study attempts to depict major clinical characteristics of acute stroke in patients with Chinese medicine treatment and to explore any difference compared with other non-Chinese medicine use cohorts and the effectiveness and safety of Chinese medicine.
Telephone surveys of female patients using liposomally-bound iron and traditional iron sulphate preparations for the management of iron deficiency anemia to determine gastrointestinal tolerability.
Randomized pilot trial of restarting DOACs at 1 week versus 4 weeks after traumatic intracranial hemorrhage
After thyroid surgery, 0.6 to 4% of patients develop postoperative bleeding. 90% of this postoperative bleeding occurs within the first 48 hours. Most of the time, the complications are rapidly progressing and require immediate attention. Up to 0.6% of patients with postoperative bleeding die. In a clinical study with postoperative pressure measurements it could be shown that postoperative bleeding without interruption leads to a continuous increase in pressure in the neck, as is observed when coughing and pressing. Systematic invasive pressure measurement in the thyroid compartment after surgery might detect a continuous increase in pressure which is often caused by a growing haematoma, indicating serious post-surgery bleeding at a much earlier time compared to state of the art diagnostic workflow. n routine clinical care, detection of serious haemorrhage depends on the patients alerting symptoms even if post-operative intermittent monitoring of vital parameters and wound conditions is performed according to current medical guidelines [18] and local instructions. Device-based, continuous haemorrhage detection within 36 to 48 hours after surgery would allow to objectively measure an increase in cervical pressure before symptoms occur, i.e. early detection of risk leading to timely therapeutic actions. Thus, the risk of serious complications like hypoxic brain damage and death caused by post-operative haemorrhage is minimized. In addition, the intervention team would be able to fine-tune necessary actions during the rescue procedure based on objective pressure values, e.g. the decision to open cutaneous sutures immediately or later in the operation theatre, and therefore reduce additional perioperative morbidity and increase patients' safety.
Surgical hip reconstruction reduces the hip joint through soft tissue releases and osteotomies of the femur and/or pelvis. Blood loss and subsequent blood transfusion are normal consequences of hip reconstruction.
Abdominopelvic bleeding can occur due to numerous causes including for the vast majority, trauma, surgery complications and tumors. Interventional radiologists often exclude arterial acute hemorrhage using cyanoacrylate or a liquid embolic agent, but few prospective results have been published to assess their efficacy and safety. The historic and most studied liquid embolic agent to date is Onyx. Results in the treatment of acute peripheral non-neurologic hemorrhage have been detailed in a meta-analysis published in 2015. This systematic review found 19 articles presenting 131 patient cases and 150 lesions treated with Onyx from 2005 to August 2014. There were 11 case series and 8 case reports but no prospective trial. The most common presenting symptoms were of gastrointestinal (GI) origin (n = 51). Rebleeding of the baseline lesion occurred in 7/131 patients. No deaths resulting from complications of the embolic procedure were reported. One patient died of persistent hemoptysis after treatment with Onyx. No deaths were directly attributable to the use of Onyx. During a peripheral embolization procedure with available embolic agents other than SQUIDPERI, residual feedings or collateral vessels became gradually less visible to the operator due to the high radiopacity of the liquid. It was therefore essential to develop an embolization system with lower radiopacity, or with radiopacity that decreases over time. Additionally, depending on the angioarchitecture and flow characteristics, it is important to have an embolic agent with various viscosities. SQUIDPERI is a liquid embolic agent with various viscosities and radiopacities. It is indicated for the embolization of lesions in the peripheral vasculature but its use is poorly reported as of today. The purpose of this prospective non interventional multicenter study is to evaluate the safety and efficacy of SQUIDPERI for the treatment of abdominopelvic arterial acute bleeding or imminent risk of bleeding.
Background: Patients with acute ischemic stroke (AIS) are at risk of hemorrhagic transformation (HT) after intravenous thrombolysis. Although there is a risk assessment model for hemorrhagic transformation after thrombolysis, there is no evidence of clinical application in the population of Guangdong Province. . Purpose: To verify the clinical application effect of the existing risk assessment model for hemorrhage transformation after thrombolysis in the local population; to improve the existing prediction model and verify the predictive value of HT after intravenous thrombolysis. Methods: (1) Continuously collect AIS patients who received intravenous thrombolysis in our hospital from January 2014 to December 2020 to verify the clinical application effects of three existing models (HAT, SIT-sICH, THRIVE) on bleeding transformation. Collect baseline and bleeding transformation information within 7 days after thrombolysis, and use ROC curve, calibration curve, sensitivity and specificity to evaluate the prediction effect. A logistic regression model was used to construct an improved HT prediction model based on the AIC principle; (2) Continuous collection of AIS patients who received intravenous thrombolysis in two local hospitals from January 2021 to December 2022 for internal and external verification. Expected results: (1) Evaluate the clinical application value of the existing prediction model in local AIS patients with intravenous thrombolysis; (2) Develop a modified risk assessment model suitable for hemorrhage transformation after intravenous thrombolysis in AIS patients in Guangdong area, and evaluate the risk early Provide guarantee for clinical diagnosis and treatment.
