Filter by:Background: Patients with decreased kidney function are in the positive acid balance due to insufficient renal acid excretion. To correct the varying degrees of metabolic acidosis in these HD patients, a high concentration of HCO3 in the dialysate is routinely used. During every 3-to-4 hours of HD treatment, a massive surge of HCO3 would enter the circulation and typically overcorrects predialysis acidosis to alkalosis and alkalemia. The sharp acid-base shift can cause some adverse consequences. The investigators believe that the rapid correction (or overcorrection) from the pre-dialysis metabolic acidosis to post-dialysis metabolic alkalosis during the 3-to-4 hours HD treatment would relate to adverse effects on HD patients. Thus the investigators conduct this study to prove the hypothesis that "prevention of post-dialysis alkalosis by using lower dialysate HCO3 concentration might cause less adverse outcomes in ESRD patients on HD." Study design: Prospective cross-over case-control study. Study population: A total of 60 patients who receive regular hemodialysis (three times per week) for more than 6 months in the regional teaching hospital.
This study aims to evaluate the efficacy and safety of sorafenib plus toripalimab for unresectable hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT).
Study will investigate & compare the left ventricular remodeling & systolic function between two groups of ST-elevation myocardial infarction undergoing primary per-cutaneous coronary intervention applying ischemic post-conditioning to one of them.
This study evaluates the usability of a new remote warning system for fall in old people. This system is integrated in a shoe. Patients hospitalized in a geriatric ward but also their informal and professional caregivers will assess the usability of the device using a structured survey.
This is a multicenter, single-arm, prospective phase II study to evaluate the efficacy and safety of a novel combination regimen for relapsed/refractory PCNSL. Specifically, ibrutinib will be administered in combination with ifosfamide, etoposide and rituximab (IBER) as a salvage chemotherapy, which is followed by maintenance ibrutinib monotherapy of fixed duration.
This a Phase I/II randomized trial for patients with relapsed refractory Multiple Myeloma who have relapsed after treatment with prior therapies. The protocol is designed to evaluate two agents, Anti-LAG-3 and Anti-TIGIT, in order to understand their immunologic effects and safety both as single agents and in combination with pomalidomide and dexamethasone. In these arms, patients will be treated with either Anti-LAG-3 or Anti-TIGIT respectively for one cycle as single agent followed by the addition of pomalidomide and dexamethasone in combination for subsequent cycles. A third arm allows patients to be treated with the FDA approved combination of elotuzumab plus pomalidomide and dexamethsone as a control. This arm will thus allow a concurrent standard of care comparator for the experimental arms.
Neuromyelitis optica spectrum disorder (NMOSD) is one common demyelinating disease of the central nervous system in young adults, with high rate of disability and recurrence, and poor natural course, which can cause a serious burden on families and society. To today, there is still a lack of prospective, multi-center, large sample clinical trial evidence for the treatment and prognosis of acute attack of NMOSD patients. This study will conduct a prospective, multi-center, single-blind, randomized controlled clinical trial of acute attacked NMOSD patients in China. The researchers plan to collect 144 NMOSD patients with acute attack in three research centers of Guangzhou (the Third Affiliated Hospital of Sun Yat-sen University, the Zhongshan Ophthalmic Center of Sun Yat-sen University, and the Guangdong 999 Brain hospital), to study the safety and efficacy of immunoadsorption therapy. The subjects will be randomized into immunoadsorption group and plasma exchange group, and the following indicators will be evaluated: (1) changes in EDSS scores and visual acuity before and after treatment; (2) changes in AQP4-IgG levels; (3) the safety of immunoadsorption treatment. This study is aimed to determine the efficacy and safety of immunoadsorption therapy for acute attack of refractory NMOSD patients, and to provide more sufficient clinical evidence for the therapy selection for acute phase of NMOSD patients.
To examine the impact of IVUS guidance on clinical outcomes in the patient with Acute ST Segment Elevated Myocardial Infarction.
The main objective of this trial is to determine feasibility and tolerance of the human body to RFA associated with local immunomodulation carried out using a thermoreversible hydrogel combined with 2 immunomodulators, GMCSF and Mifamurtide. The main endpoint of the study is the feasibility, the frequency and the nature of per and post-operative adverse events of the in situ injection of an immunomodulatory hydrogel after radiofrequency of unresectable colorectal liver metastases. The secondary objective is one-year progression free survival rate.
The objective of this study is to evaluate the effect of treatment with semaglutide 1.34 mg/ml in combination with empagliflozin 25 mg, compared to treatment with empagliflozin 25 mg in combination with placebo on albuminuria in participants with type 2 diabetes and albuminuria. In a randomised, placebo-controlled, double-blinded, parallel trial we will include 80 patients with type 2 diabetes and albuminuria. Patients will start in a run-in phase of 26 weeks with empagliflozin 25 mg alone. After that, the patients will be randomised 1:1 to an active treatment period with semaglutide of 26 weeks or placebo for 26 weeks. The primary endpoint is change from randomisation to week 52 in albuminuria, measured in three morning urine samples.
