Filter by:this study evaluates the use of Kagocel for the prevention of acute respiratory viral infections (ARVI) and influenza during the epidemic rise in morbidity in Russia in the 2017-2018 season (epidemiology: number of cases during the period of taking Kagocel and follow-up, severity of the disease, bacterial exacerbations, number of repeated episodes (reinfection); patients demography; safety) in health care workers who are at risk.
The purpose of this study is to test whether Daratumumab-SC, a drug that eliminates antibody-producing plasma cells, can effectively lower the level of preformed antibodies in patients awaiting heart transplantation. These preformed antibodies limit the number of donor hearts that are compatible for the patients. If Daratumumab-SC can effectively remove preformed, donor-specific antibodies, then highly allosensitized patients will have more compatible hearts available to them, potentially decreasing transplant waitlist time and reducing mortality.
The primary objective of this study is to determine the impact of anti-checkpoint immunotherapy on type 2 inflammation via a retrospective analysis of % eosinophilia.
Endoscopic Retrograde Cholangiopancreatography (ERCP) is one of the most technically challenging procedures in gastrointestinal endoscopy. Selective deep cannulation is a critical step for the performance of ERCP. The incidence of difficult cannulation has been reported in many studies, ranging from 10% to 40% in patients with native papilla. Difficult cannulation is an independent risk factor for post-ERCP pancreatitis (PEP). The definition of difficult cannulation has been proposed by European Society of Gastrointestinal Endoscopy (ESGE) guidelines. Initial cannulation is considered difficult with the presence of one or more of the following: more than 5 min for attempting to cannulate; more than 5 contacts with the papilla; more than 1 unintended pancreatic duct cannulation or opacification. The clear definition of difficult cannulation is important for making decisions during or after ERCP, including determining the appropriate time to transfer to advanced cannulation techniques (e.g. early precut) and whether prophylactic methods should be administrated to reduce the risk of PEP. Although 5-5-1 criteria have been widely used during ERCP practice or in relevant studies, it remains unclear whether the current criteria are suitable for the cannulation procedure with trainee involvement. Because of inexperienced manipulation of the scope and accessories, the involvement of trainees generally increases the overall cannulation time and attempts, which are the two important parameters in the criteria of difficult cannulation. Thus, the investigators hypothesized that the definition of difficult cannulation in trainee-involved cannulation might be different from the traditional 5-5-1 criteria.
This multicenter study aims to include 15000 participants undergoing screening upper gastrointestinal endoscopy and establish a risk prediction model for esophageal squamous cell carcinoma and esophagogastric junctional (EGJ) adenocarcinoma in high-risk areas. The prediction model will be built based on epidemiological and cytological features, acquired from the esophageal sponge cytology test. The primary study outcome is the diagnostic performance of the model to detect high-grade lesions (including carcinoma and high-grade intraepithelial neoplasia) of the esophagus and EGJ. Secondary outcomes include the number needed to screen, and dignostic performance of cytologist under AI assistance and abnornal cell count.
This open label randomized controlled multicenter phase II trial will evaluate the clinical impact of the use of HFNC vs. conventional oxygen therapy in patients with moderate and severe hypoxemic acute respiratory failure secondary to SARS-CoV-2 infection.
To identify the effectiveness of two mouth sprays at relieving symptoms of xerostomia in patients who have received radiation for carcinoma of the head and neck. To assess patient quality of life and mouth acidity following use of two mouth sprays meant to relieve symptoms of xerostomia in patients who have received radiation for carcinoma of the head and neck.
Transcranial photobiomodulation (tPBM) is a novel, non-invasive neurostimulation technique, which has shown compelling potential for cognitive improvement. Increasing neuroimaging studies have demonstrated that functional brain network models would sensitively and comprehensively delineate action mechanisms of multiple neurostimulation techniques. However, the action mechanism of tPBM based on functional brain network remain largely unknown. In this project, the investigators aim to investigate the effectiveness of tPBM on working memory for healthy older adults. Taking the randomized, single-blind controlled method, participants in the active tPBM group will take active tPBM, and those in the sham tPBM group will take sham tPBM. After that, the investigators will investigate the changes of working. Furthermore, based on the neuroimaging technique, the regulatory mechanism of tPBM in intervening older adults will be revealed from the perspective of altered brain functional networks. This study will provide evidence for understanding whether the tPBM has the potentially therapeutic effect on cognitive function for healthy older adults as a non-drug treatment, and further elucidating the potential brain mechanism, which are of great values in solving scientific and clinical practice issues.
The leading cause of primary hyperparathyroidism (pHPT) is a solitary adenoma (89%). The treatment of pHPT is generally surgical removal of the overactive parathyroid gland(s). Since a solitary adenoma is the predominant cause, parathyroid surgery is preferably performed through a minimally invasive parathyroidectomy (MIP) in which only the suspected adenoma causing the pHPT is resected in a focused manner. To facilitate the performance of a MIP, accurate preoperative imaging is pivotal. This study aimed to analyze the diagnostic performance of 11C-choline PET/CT after prior negative or discordant first-line imaging in patients with pHPT undergoing parathyroid surgery with an optimized imaging protocol.
Spinal anaesthesia for elective caesarean section is associated with maternal hypotension, secondary to alteration of sympathetic tone and hypovolemia, in up to 70% of cases. Our objective, in this prospective single-centre observational study, was to assess the ability of change in systolic ejection volume after 45° passive leg raising to predict hypotension after spinal anaesthesia. Systolic ejection volum was monitored with non-invasive Clearsight Device just before elective caesarean section in third trimester pregnant women.
