Active clinical trials for "Inflammation"

The prevalence of obesity is steadily growing in many parts of the world in order to reach epidemic proportions. Changes in signaling pathways state of hunger and satiety contribute to the increase in obesity and metabolic syndrome. Currently, the white adipose tissue, also is considered a secretory tissue by producing numerous adipokines involved in a chronic state of inflammation, which may interfere with the neuroendocrine regulation of energy balance that affect the weight loss process. The bariatric surgery is recommended as the most effective tool in the treatment and control of morbid obesity. The study population will consist of patients undergoing bariatric surgery of type Roux-en-Y gastric bypass. The study was performed in Clinical Hospital of the Federal University of Paraná (UFPR). This is a prospective cohort study with follow up of 6 and 24 months. The aim of this study is to assess the effects of weight loss after bariatric surgery associated anthropometric characteristic, metabolic changes (glucose, cholesterol profile,hepatic enzymes, Fibroblast growth factor- 21(FGF-21), blood pressure), the profile of adipokines pro/anti-inflammatory (adiponectin, interleukin-6 (IL-6),interleukin-10 (IL-10), C reactive protein (CRP), plasminogen activator inhibitor-1 (PAI-1), tumor necrosis factor alpha (TNF-α), intercellular adhesion molecule-1 (ICAM-1), resistin, frizzled-related protein 5 (SFrp5) and neuroendocrine regulation of energy balance (leptin, neuropeptide Y (NPY) , alpha-melanocyte stimulating hormone (α-MSH), melanin-concentrating hormone (MCH) and agouti-related peptide (AgRP), as well as the quality of life in obese adults.

This study will be the first to test whether a selected anti-inflammatory agent, methotrexate, reduces inflammation in a human body, improve cognitive and physical function, and reduce pain levels in older adults at risk for functional decline, due to systemic inflammation.

To study the effects of green coffee supplement on adropin, irisin, vaspine, systemic inflammation and oxidative stress in breast cancer survivors.50 breast cancer survivors who their treatment is over and referred to follow breast cancer clinic with will be randomly allocated to receive placebos or 2 capsules green coffe for 12 weeks; both groups will be advised to adherence the investigators' diet and exercise program too. At the first and the end of the intervention, adropin, irisin, vaspine, systemic inflammation and oxidative stress will be assessed and compared between groups.

Total amputation therapy; is a treatment method aimed at maintaining the vitality of the radicular pulp remaining as a result of complete removal of coronal pulp tissue. In cases where pulp is exposed due to caries or trauma, the pulp is vital, bleeding can be controlled during the procedure, no periapical pathology is seen and radicular pulp is healthy. Traditionally, acute pulp pain is thought to be a symptom of irreversible pulpitis, and it is thought that there is little chance of the pulp returning to its normal situation after removal of the irritants. Root canal treatment has been accepted as the gold standard for the treatment of these symptoms. In recent studies, spontaneous or severe pain before procedure has not always indicated that pulp has no repair capacity, and deep carious lesions are not necessarily associated with irreversible pulpal pathology. Histological studies showed that even when caries reach the pulp or degeneration and inflammation were seen in it, there was a healthy section still present in the pulp. Therefore, it is stated that the healthy pulp remaining as a result of total amputation performed by removal of degenerated pulp can be preserved. Furthermore, it is stated that for the healing potential of the remaining pulp tissue, the original signal should be that the bleeding can be controlled after the amputation of the infected pulp tissue. While the most popular method in the treatment of vital pulp is CaOH, the American Academy of Pediatric Dentistry has been reported to be more resistant to dissolution in the protocol in recent years. MTA is a more suitable material because it is more homogeneous, and forms a thicker dentin bridge. However, the MTA requires a long time to harden, it is difficult to manipulate and color. In recent years, researchers have focused on creating new MTA formulations to improve their physicochemical properties without affecting their biocompatibility and bioactivity. NeoMTA Plus is a new fine powder tricalcium silicate. It consists of a water-based gel and powder mixture and the powder-gel mixing ratio may vary depending on the area of use. It is a material similar to MTA Plus. However, in order to avoid tooth discoloration, tantalium oxide used instead of the bismuth oxide and required calcium hydroxide used to induce the formation of mineralized tissue.

Hypertension is a leading risk factor for morbidity and mortality worldwide. The brain is a major target of the damaging effects of hypertension. Hypertension has been recognized as the leading cause of dementia as well as the most important risk factor for stroke and vascular cognitive impairment. Although glucose is the principal cerebral energy source, impact of hypertensive treatment on cerebral glucose metabolism is poorly understood.

The REDJUVENATE Trial proposes to test the hypothesis that postoperative organ injury and inflammation will be less if patients undergoing cardiac surgery who are at risk of large volume blood transfusion (defined as the administration of ≥4 units of red cells) receive rejuvenated washed cells compared to standard care (unwashed aged stored cells).

INTRODUCTION: Cerebral amyloid angiopathy-related inflammation (CAA-ri) is a very rare manifestation of cerebral amyloid angiopathy, characterized by acute/subacute neurological deterioration and T2/FLAIR corticosubcortical or deep white matter hyperintensity. With the advent of new diagnostic criteria, there are more and more case reports and series reported; nevertheless, MRI findings and follow-up data need to be thoroughly described. OBJECTIVES: Our aim in this multicentrical and retrospective study was to describe the clinical and radiological features of patients with CAA-ri and assess long-term prognosis. METHODS: We reviewed the characteristics of 28 patients with CAA-ri including clinical data, systematic MRI analysis, cerebrospinal fluid results (including Alzheimer's disease biomarkers) and APOE genotype. HYPOTHESIS: We aimed at describing the clinical and radiological characteristics of a cohort of patients with CAA-ri.

This study evaluates the use of an additional hemoadsorption device in adult patients undergoing veno-arterial extracorporal membrane oxygenation (ECMO) following cardiac arrest and cardiopulmonary resuscitation in respect to its effects on post resuscitation inflammatory syndrome. At implantation of the ECMO the participants are going to be randomized into a treatment and a control group. The first will be outfitted with a polymer-based adsorption device implemented in the extracorporal circulation established by ECMO for 48h, the control group is going to be treated by ECMO and standard intensive care alone. To detect any significant differences in terms of inflammatory response and patient outcome the investigators will regularly determine the blood levels of certain cytokines in fixed intervalls. In addition, the investigators are going to compare secondary clinical outcome parameters like organ disfunction and 30d mortality.

Heart failure (HF) is the leading cause of death in US. It is associated with abnormal vascular function termed endothelial dysfunction. It is also associated with increased stress on the blood vessels and high levels of inflammation. Vagus nerve stimulation can help improve inflammation, vascular function and vascular stress. The investigator has recently completed a study showing that 1 hour of noninvasive vagus stimulation can improve vascular health. However, it is unknown if 4 weeks of stimulation will be beneficial in systolic heart failure. The purpose of this study is to determine if transcutaneous vagal stimulation (TVS) will lead to improvement in the function of the inner lining of participants' arteries, memory, and in the levels of certain chemical markers of arterial function in the blood. Participants will be randomized to receive either TVS or a sham stimulation and undergo 4 weeks of stimulation. Vascular function will be assessed by several non-invasive measurements, including Flow Mediate Dilation (FMD), Pulse Wave Analysis (PWA), EndoPAT, and Laser Speckle Contrast Imaging (LSCI). Participants' memory will also be measured through electronic assessments and blood will be collected and analyzed for arterial function chemical markers.

Metabolic Syndrome (MetS) and cardiovascular disease are associated with systemic inflammation (SI). Activation of the mechanisms of inflammation is triggered by the inflammatory cytokines. Τhe NLRP3 inflammasome is activated by microbial-derived low molecular weight (LMW) factors, short chain fatty acids (SCFAs), pathogen-associated molecular pattern molecules (PAMPs), damage-associated molecular pattern molecules (DAMPs), and monosodium urate crystals. Probiotics can regulate inflammation in two ways: 1) indirectly, by producing SCFAs as well as increasing synthesis of antimicrobial peptides and 2) directly, by binding innate immune system receptors Toll-like (TLR 2, 4, 9) and triggering important signaling pathways associated with activation of NLRs affecting the formation of inflammasome, thus the inflammatory response.
