Filter by:In patients with symptoms of infection, tissue injury and inflammatory disorders the study will evaluate agreement between the CRP measurements from the LumiraDx POC CRP assay and the Siemens Dimension Xpand Plus CRP assay, as an aid in evaluation and detection of infection, tissue injury and inflammatory disorders.
This project is a randomized controlled non-inferiority study that aims to cover knowledge gaps about the composition and development of plasma proteins, inflammation markers and mental health in Norwegian, voluntary, and unpaid blood donors who donate plasma and blood. We will include 120 male blood donors who are randomized into three groups, the first donating plasma by plasmapheresis 3 times every 2 weeks, the second donating plasma by plasmapheresis every 2 weeks and the third donating whole blood every 3 months. Blood sample analyses are done before, every 2 weeks during the donation period and after the donation period. Questionnaires regarding mental symptoms, Hopkins Symptoms Checklist 25, are done before and after the donation period. The donations extend over 16 weeks and the participants are followed up with blood tests 2 and 4 weeks after the last donation. A plasma sample from each sampling will be stored in an biobank in Innlandet Hospital Trust. The donation frequency are based on the Council of Europe's latest guidelines for plasmapheresis which allow 33 plasma donations per year with at least 96-hour intervals and previous national guidelines. The project is useful to ensure that frequent plasma donations, which are necessary to increase plasma production and the degree of self-sufficiency of plasma products in Norway, do not pose a health risk to blood donors. The primary objective is to assess the safety of blood donors donating plasma, by comparing the change in total protein and immunoglobulin G concentrations between donors who will be donating plasma 3 times every 2 weeks with donors donating plasma every 2 weeks and blood donors donating regular whole blood every 3 months. The secondary objectives are to compare the concentrations of other plasma proteins and inflammation markers and describe the development of these during plasma and blood donations between the three donations groups, compare the dropout rate and the degree of psychological distress measured by Hopkins Symptoms Checklist 25.
Periodontitis (gum disease) is a chronic inflammatory disease linked to a imbalance of oral microbiome. The most usual treatment involves removal of sub and supra-gingival plaque and calculus otherwise known as Non-surgical periodontal therapy (NSPT). Ample evidence now indicates that Periodontitis and NSPT are linked to both local and systemic inflammation. This in turn also explains the association between periodontitis and a number of systemic diseases including cardiovascular diseases. Vascular endothelium (the innermost lining of blood vessels) exerts protective, anti-inflammatory and anti-clotting functions. As the endothelium ages, and is exposed to the damaging effects of traditional cardiovascular risk factors such as elevated blood pressure, serum cholesterol, glucose and cigarette smoking; these protective properties appear diminished, leading to a state of endothelial dysfunction (ED). Understanding the mechanisms of ED in humans could lead to new therapeutic and/or preventive strategies of CV diseases. Sufficient evidence now suggests that periodontitis and its treatment (removal of sub and supra-gingival plaque and calculus-periodontal therapy) are linked to endothelial dysfunction. Studies have extensively characterized the time-course of a single session of non surgical periodontal treatment (IPT) associated with a one week acute inflammatory response. This substantial inflammatory response is also associated with ED assessed by flow-mediated dilation (FMD) of the brachial artery at 24 hrs. Photodynamic therapy (PDT) helps kill the local pathogens, thus preventing their systemic dissemination; which may ultimately reduce the systemic host inflammatory response generated.
Chronic liver disease is a major healthcare problem in Hong Kong and worldwide. The diagnosis of liver fibrosis and inflammation in patients with chronic liver disease has important prognostic and therapeutic implications. The current gold standard to evaluate and stage the severity of liver fibrosis and inflammation is based on liver biopsies, which are invasive and impractical for screening and monitoring the disease. The existing non-invasive methods still have significant limitations to meet the challenge. Magnetic resonance effect can be used to obtain the molecular-level information on the biochemical properties of human tissues. The investigators will develop non-invasive quantitative MRI technologies to evaluate and stage liver fibrosis and inflammation. Our approaches are based on the endogenous contrast mechanism and thus do not need to inject an MRI contrast agent. Our approaches can be implemented on a regular MRI scanner and do not need any extra hardware. To enable the technology for routine clinical use, the investigators will develop fully automated post-processing techniques for the proposed MRI acquisition approaches. The investigators will perform multi-center clinical studies in Hong Kong and mainland China to validate our imaging measurements by histopathologic results from liver biopsies on patient cohorts.
Aortic stenosis (AS) is the most common valvular heart disease in the developed world. Once symptomatic, untreated patients have a poor prognosis with five-year survival rate of 25%. Once at an advanced stage, AS will lead to the development of left ventricle hypertrophy, and eventually heart failure and death. At-present, there is no effective medical therapy for aortic stenosis. Current management of patients with AS consists of 'watchful waiting'. Valve replacement is needed when these patients (often acutely) become symptomatic. Recent studies have shown that inflammatory processes with similarities to atherosclerosis play an important role in AS. Therefore, we hypothesize that treatment with anti-inflammatory therapy, in the form of colchicine, could reduce the progression of AS. If positive, this trial will be the first to provide a potential therapeutic option for millions of people world-wide with AS.
This clinical trial aims to investigate the effects of a decline in methamphetamine use on rectal inflammatory cytokine levels, substance use contexts, and HIV/STI risk behavior. This clinical trial also seeks to evaluate joint effects of methamphetamine use and rectal gonorrhea/chlamydia infection on rectal inflammatory cytokine levels. The proposed trial will consist of 40 MSM, half with rectal gonorrhea/chlamydia infection at enrollment (n=20), with methamphetamine use disorder that will receive contingency management for methamphetamine reduction. Following baseline measurement, participants will be observed over the course of 8 weeks, where participants will complete behavioral surveys, provide urine for drug testing, and rectal samples for measurement of rectal inflammatory cytokine levels.
The purpose of this biological study is to provide Dr. Samuel Fortin's laboratory with a continuous supply of blood mononuclear cells (PBMCs) so that he can pursue research on the potential beneficial effects of monoglyceride omega-3 fatty acids on the resolution of inflammation.
Infants and children undergoing cardiac surgery with cardiopulmonary bypass (CPB) can experience systemic inflammation that prolongs post-operative recovery. Ultrafiltration is an intra-opreative technique that is hypothesized to extract circulating inflammatory mediators during the CPB time. There have been only a few small studies looking at a limited number of inflammatory marker profiles in this context. Our institution uses an innovative form of ultrafiltration "subzero-balance simple-modified ultrafiltration" (SBUF-SMUF) throughout the entire CPB time. SBUF-SMUF has been our standard of care for the last 5 years. This observational seeks to describe the clinical and immunologic outcomes of infants and children undergoing cardiac surgery with CBP and SBUF-SMUF.
Evaluate the correlation between altered glycometabolic status and joint inflammation in diabetic patients with osteoarthritis undergoing knee replacement surgery
The purpose of this study is to determine if ceftriaxone administered postoperatively via intravenous injection reduces postoperative visual analog scale (VAS) pain scores and narcotic consumption in patients undergoing knee arthroscopy for a cartilage or meniscal injury.
