Prospective, post-marketing, multi-center, open-label study to explore if the initiation of adalimumab could influence grey-scale (GS) and power Doppler (PD) ultrasonographic (US) score using 36-joint plus 4-tendon scoring system, and validate the applicability of different simplified US joint scoring systems.
Coronary flow reserve (CFR, calculated as the ratio of hyperemic over rest myocardial blood flow) is emerging as a powerful quantitative prognostic imaging marker of clinical cardiovascular risk. CFR provides a robust and reproducible clinical measure of the integrated hemodynamic effects of epicardial coronary artery disease (CAD), diffuse atherosclerosis, and microvascular dysfunction on myocardial tissue perfusion. Inflammation is a key mediator of this constellation of abnormalities, affecting the entire coronary vasculature, but no clinical trial to date has shown that directly reducing inflammation lowers cardiovascular event rates. As such, the recently launched Cardiovascular Inflammation Reduction Trial (CIRT) provides a unique opportunity for mechanistic investigation of the impact of anti-inflammatory therapy on changes in CFR as a reflection of coronary vascular dysfunction, which may precede clinical outcomes, particularly in patients at high-risk of events. The investigators are ideally positioned to examine the impact of inflammation on CFR, having extensive experience in both the quantitation of CFR using clinically-integrated dynamic positron emission tomography (PET) and the ability to assess its association with cardiovascular outcomes. The central hypothesis of this ancillary proposal, CIRT-CFR, is that reducing systemic inflammation using low-dose methotrexate (LDM) will, compared to placebo, quantitatively improve myocardial blood flow and coronary flow reserve as measured by PET over one year, in stable CAD patients with type 2 diabetes or metabolic syndrome enrolled in CIRT. In so doing, improvement in coronary vasoreactivity, endothelial function, and tissue perfusion may have beneficial effects on myocardial mechanics, left ventricular deformation and function and, ultimately, symptoms and prognosis.
Background: Multiple sclerosis (MS) affects the brain, spinal cord, and optic nerves. MS lesions can appear on the MRI (magnetic resonance imaging) scans in many ways. Sometimes they light up from the outer edge and fill inward. This is called ring enhancement. Researchers think this type of lesion may not heal as well as others. Corticosteroids are the standard treatment to reduce symptoms of MS relapse. But there is no standard treatment for people with enhancing MS lesions without signs of MS relapse. Researchers want to see if a short-term high-dose course of corticosteroids helps heal those lesions. Objective: To study the effects of short-term high-dose corticosteroids on ring-enhancing MS. Eligibility: Adults ages 25 and older who: - Have MS and a rim-enhancing lesion on a prior brain MRI - Are enrolled in another NINDS protocol Design: Participants will be screened under another protocol Participants will be randomly assigned to get either no treatment or 3 days of treatment with a corticosteroid. Participants will have: - 1 baseline visit - 3 days of high-dose steroids, intravenous or oral. If IV, participants will receive methylprednisolone by IV each day. Participants will also be prescribed medicine to protect their stomach. - Follow-up visits will be at week 13 and week 25 after randomization to treatment or no treatment. Visits include medical history and physical exam. Participants will have blood and urine tests. Participants will also have neurological exams and MRIs. Participants lie on a table that slides into a cylinder. They are in the scanner 1.5-2 hours. They get a dye through a catheter: A needle guides a thin plastic tube into an arm vein.
In this study, the investigators aim to determine whether non-invasive autonomic modulation decreases inflammation and complications after thoracic surgery. The investigators will test the hypothesis that low-level transcutaneous vagal nerve stimulation (LLVNS) during major thoracic surgery reduces inflammation and complications, particularly postoperative atrial fibrillation (POAF). This will be a prospective randomized pilot trial of 200 patients undergoing major thoracic surgery including lobectomy, bilobectomy, or pneumonectomy via either video-assisted thoracoscopic (VAT) or open thoracotomy. Patients will be randomized to receive ether a) LLVNS (n=100) or b) sham LLVNS (n=100) during their procedure. All patients will receive standardized anesthetic, surgical, and post-surgical care. The primary outcome in this study will be time to occurrence of in-hospital POAF, which will be compared between groups using Cox proportional hazards models. Secondary outcomes will be ICU and hospital length of stay, postoperative morbidity, postoperative mortality, and serologic markers of inflammation.
The purpose of this study is to analyze the Ketamine with its anti-inflammatory profile would be able to prevent cognitive disorders in the postoperative period of cardiac surgery, since these disorders contribute to an impact on morbidity / mortality in this population.
A Mediterranean dietary pattern emphasizing an abundance of plant-based foods including nuts, moderate intakes of fish, poultry and low-fat dairy products, and use of extra virgin olive oil as the main source of fat has been associated with reduced risk of cardiovascular disease (CVD), and such a pattern has been advocated by the 2015 U.S. Dietary Guidelines Advisory Committee. The strongest experimental support for this recommendation derives from the success of the recent PREDIMED CVD outcomes trial, and studies indicating that a Mediterranean-style diet improves lipoprotein and oxidative markers of cardiovascular disease risk in comparison to either low-fat or Western dietary patterns. However, in none of these studies were comparisons made between the effects of Mediterranean-style diets with low-/nonfat vs. full-fat dairy foods. The overall objective of the present proposal is to determine whether the inclusion of full-fat rather than low- and nonfat dairy foods in a Mediterranean dietary pattern based on that used in the PREDIMED study results in similar improvements in biomarkers of CVD risk. Specifically, we will test the hypotheses that 1) a standard Mediterranean diet will lower LDL-C and apoB compared to a Western diet; 2) modification of the Mediterranean diet by replacing low-fat dairy products with high-fat dairy (3 servings/day; high-dairy fat Mediterranean diet) will not significantly increase LDL-C and apoB but may raise large buoyant LDL particles compared with a standard Mediterranean diet; and 3) the high dairy fat and standard Mediterranean diets will result in comparable reductions in levels of inflammatory markers and oxidized LDL, and improvements in endothelial function compared to a Western diet.
The main objective of this research is to investigate the effect of addition of fiber on the high fat high carbohydrate (HFHC) meal induced inflammation and oxidative stress mechanisms at the molecular level in humans, in vivo. The investigators have previously shown that the intake of one HFHC meal leads to an increase in oxidative stress and inflammation. HFHC meal also induces an increase in the expression of suppressor of cytokine signaling- 3 (SOCS-3) in the mononuclear cells (MNC), which interferes with insulin signal transduction and contributes to the pathogenesis of insulin resistance. In contrast, an American heart association (AHA) meal rich in fruits and fiber does not induce these effects. These observations are important since HFHC meal not only induces oxidative stress and inflammation but also lays the foundations of a potentially greater insulin resistance through the induction of SOCS-3, TLR-4 and TLR-2.
This is a randomised double-blinded placebo-controlled multi centre study in 98 patients with ACPA positive arthralgia. The study is composed of 2 arms with a 1:1 randomisation at baseline: Treatment phase will be 6 months. Group 1: Abatacept s.c. 125 mg weekly for 6 months vs. Group 2: Placebo s.c. for 6 months. After 6 months both groups will run into the follow up period for another 12 months up to month 18. Patients developing arthritis will be treated according to local guidelines.
This is a cross sectional case controlled study to assess lung microbiome and inflammation in smokers with and without Chronic Obstructive Pulmonary Disease (COPD). Investigators will look at active bacterial metabolic pathways in the lower airways using metagenomic and metabolomic approaches an assess relationships among microbiome, metagenome, metabolome and host immune responses in COPD and controls. Investigators believe COPD cases will have higher prevalence of pneumotype supraglottic predominant taxa (SPT) than matched controls.
