Filter by:A suture is a biomedical device that is made of natural or synthetic materials. Sutures are used to close tissue surfaces until wounds heal and regain their ability to withstand normal stresses. Although different suture materials are available for various dental procedures, clinicians commonly neglect to select sutures based on their mechanical properties and capabilities. Instead, clinicians rely on their clinical experience to determine which suture material will suffice for wound closure and healing. To our knowledge, there have been no published studies detailing the results of mechanical testing on sutures after clinical application. The aim of this study is to clinically, histologically, and mechanically assess the four common sutures used in periodontal and dental surgery, with the hopes of providing clinicians with a guide that will allow them to choose sutures based on the clinical, histological, mechanical properties that best fit the stress and strain applied to the wound.
This prospective study evaluates the pregnancy results after laparoscopic endometriosis operation in infertile patients with ERROR (endometrioma related reduction in ovarian reserve)
The aim of this study is to investigate the efficacy and safety of anrotenib plus toripalimab in the treatment of advanced esophageal squamous cell carcinoma. In addition, the investigators will explore the possible mechanisms of anrotinib combined with toripalimab in advanced esophageal squamous cell carcinoma, and screen out biomarkers that can predict the efficacy of combination therapy.
The purpose of this study is to evaluate the safety and efficacy of SCT-I10A combined SCT200 or SCT-I10A combined SCT200 plus chemotherapy in advanced esophageal squamous cell carcinoma and colorectal cancer
DETERMINE trial is a prospective multicenter multinational cohort study. This study will be carried out to predict the risk of bloodstream infections (BSIs) or other types of invasive infection with carbapenem resistant K.pneumoniae in patients being colonized by CRKp. The results of DETERMINE trial would be quite important to prevent unnecessary coverage of carbapenem resistant Klebsiella pneumoniae in empirical treatment of colonized patients. In this study, both risk score model and decision tree algorithm will be constructed and compared with each other in terms of sensitivity, specificity, positive predictive value and negative predictive value.
The purpose of this study was to assess the efficacy and safety of individualized treatment of 6-mercaptopurine (6-MP) in Chinese children with acute lymphoblastic leukemia, and to investigate the dose-concentration-response (DER) relationship between thiopurine metabolites and adverse events. The individualized administration of 6-MP was established in Chinese children with acute lymphoblastic leukemia.
Background & Rational: Antibiotics are a major underpinning of modern medicine. The global rise of antimicrobial resistant (AMR) organisms is a serious world health problem. With few new antimicrobial drugs on the horizon, it is imperative that we develop novel approaches to extend the service life of our existing drugs. AMR is a complex problem that is being driven by a wide range of factors. More than half of the antibiotics prescribed have no medical benefit, and outpatient visits for uncomplicated urinary tract infections (UTIs) are a major contributor to this problem. Recent studies have shown that nearly half of people treated for UTIs receive the wrong frontline drug and in 75% of patients, the duration of therapy is inappropriate. Limitations in the current diagnostic technology make it impossible to identify UTI pathogens and measure their antibiotic sensitivities during the short out-patient clinical visits that are typical for most UTI patients. These circumstances result in the inappropriate use of stronger than necessary or inappropriate antimicrobials. The aim of this study is to develop and evaluate a system that can detect bacteria in urine and find the best antibiotic in under 4 hours, thus enabling a rapid diagnosis and use of the most appropriate and cost-effective antimicrobial agent for the agent detected.
The death of prostate cancer patients is mainly due to metastatic castration-resistant prostate cancer. Though some new therapies has been tried to prolong the life-span of mCRPC patients, a dilemma was encountered for the drug-resistance. The PSMA RLT has been tested its efficacy and safety for the therapy of these patients. In our clinical trial, a new PSMA ligand will been used to be labeled with Ac225. This will be a prospective pilot clinical trial. 20 mCRPC patients who was incapable of 2rd ADT or chemotherapy will be recruited in this clinical tiral. The efficacy and safety of 225Ac-PSMA will be evaluated after the administration.
Studies have shown that the lifetime risk of developing symptomatic knee osteoarthritis is 40% in men and 47% in women; and the risk can be increased to 60% when the patient's BMI reaches 30 kg/m2. In this population, knee replacement is the most common, effective, and cost-effective method in all treatments with reducing pain, improving joint function and quality of life. Postoperative cognitive dysfunction (POCD) is a common complication in the elderly, and its incidence can reach 25-40% in major non-cardiac surgery. As for POCD can prolong hospital stay, increase mortality and morbidity, and increase social and economic burden, it is especially important for the prevention and treatment of POCD. However, The mechanism of POCD is still unclear. Studies suggest that it may involve inflammation and oxidative stress in the central nervous system. But for the elderly, they are in a state of low inflammatory response. At the same time, surgery and tourniquets also can trigger or aggravate inflammatory response. Once the inflammatory factors released into the blood circulation, they can act on the central nervous system in a variety of ways. As a result,elderly patients are more likely to develop POCD. In addition, some studies have shown that pain can also increase cognitive burden. Aspirin, its pharmacodynamic effects includes anti-inflammatory and analgesic effects which may have a certain effect on the prevention of POCD.
The aim of this study is to examine the relationship between trunk control and lower extremity selective motor control during the movement of sit to stand (STS) in children with cerebral palsy (CP).
