Filter by:Physical activity performed in the postprandial state has the ability to blunt postprandial glycemia acutely, even as a result of very light or small amounts of postprandial physical activity. Postprandial physical activity decreases postprandial glycemia more effectively than activity performed in the post-absorptive state. However, studies comparing postprandial and postabsorptive physical activity have measured glycemic outcomes in only short periods of time (hours) or have used a very large dose of physical activity. Physical activity have the ability to entail an acute increase in markers of systemic inflammation.Previous studies has also shown that systemic inflammation is increased during glycemic spikes, such as after a high carbohydrate load. Therefore the effect of postprandial physical activity is difficult to predict. One one hand it might increase markers of systemic inflammation. On the other hand it might decrease systemic inflammation as a result of a blunting effect on postprandial glycemia. The effect of physical activity after carbohydrate intake might therefore also differ from postabsorptive physical activity. Purpose of the study: I) The investigators hypothesized that light physical activity performed in the post-prandial sate decrease blood glucose in a day and night cycle compared to the same activity performed in the postabsorptive state and a control day. II) To test whether postabsorptive and postprandial light physical activity do affect markers of systemic inflammation different. 12 participants diagnosed with hyperglycemia but not on hypoglycemic medication took part in a randomized cross-over trial with 3 test days. A control day with no physical activity, and two days similar to the control day except that one of them contained a one hour bout of treadmill walking prior to breakfast and the other a similar exercise bout after breakfast. Continuous glucose monitoring was performed from start of exercise / breakfast until the morning next day (at least 22 hours). Venous blood was also sampled at given timepoints (before exercise / before breakfast, and 1.5, 2.5, 3.5 and 24 hours after breakfast. Dietary intake was individually standardized prior to and during test days.
This project aims to evaluate whether a dose-response relationship exists between dose of polyunsaturated fatty acids (PUFA), delivered as eicosapentaenoic acid (EPA), and change in markers of inflammation, and whether these effects differ from placebo. A key secondary aim is to evaluate the antidepressant effectiveness of EPA in overweight adult outpatients with current major depressive disorder (MDD). To address these aims, the project will use a four-arm, randomized, parallel-group, placebo-controlled design comparing placebo versus three doses of EPA (1 gm/day, 2 gm/day, or 4 gm/day) administered over 12 weeks. The study is to be conducted at two sites: Emory University School of Medicine, and Massachusetts General Hospital. Eligible participants will be between the ages of 18-80 who have current MDD, are overweight, and who demonstrate peripheral inflammation, defined as an high sensitivity C-reactive protein (hs-CRP) level ≥ 3 mg/L. The primary outcome will be change in plasma interleukin-6 (IL-6) levels and/or mitogen-stimulated peripheral blood mononuclear cells (PBMC) Tumor Necrosis Factor-alpha (TNF-α) expression levels in EPA- versus placebo-treated participants. The results of this investigation are intended to be used to design and power a larger definitive test of the efficacy and biological effects of EPA in patients with major depressive disorder.
The investigators aim to investigate inflammation of cranial and meningeal arteries during pharmacologically induced migraine attacks, using ultrasmall superparamagnetic iron oxide (USPIO) nanoparticles and black blood imaging (BBI) MRI.
Atrial fibrillation (AF) is the most common cardiac arrhythmia. In previous experimental studies, the investigators found that low-level vagus nerve (VN) stimulation (LLVNS), at voltages substantially below that which slowed the sinus rate, significantly suppressed AF inducibility and decreased AF duration. The investigators subsequently developed a non-invasive neuromodulatory therapy, in which LLVNS was delivered to the auricular branch of the VN located at the tragus, the anterior protuberance of the outer canine ear (low level tragus stimulation; LLTS). The anti-arrhythmic effects of LLTS were similar to those of LLVNS delivered to the cervical VN trunk. More recently, in a proof-of-concept study in humans, the investigators showed that in patients with drug-refractory AF undergoing AF ablation, LLTS for just one hour significantly shortened the AF duration and decreased inflammatory cytokines. The overall objective of this proposal is to translate in ambulatory patients with paroxysmal AF the results of previous studies showing acute suppression of AF and inflammation in anesthetized canines as well as humans, in order to examine the long-term therapeutic effects of this approach. The investigators hypothesize that intermittent (1 hour daily) LLTS for 6 months may result in long-term decrease of AF burden and suppression inflammatory cytokines in patients with paroxysmal AF. Patients will be randomized to either active or sham LLTS. LLTS will be delivered through a transcutaneous electrical nerve stimulation (TENS) device for 1 hour daily over a 6-month period. AF burden will be defined as the percent of time spent in AF over a 2-week period, assessed by noninvasive continuous ECG monitoring at baseline and at 6 months. In addition, blood samples will be collected from patients at baseline, and at 3 and 6 months, for cytokine measurement. These investigations will establish the first evidence of the long-term effects of LLTS on AF suppression in patients with paroxysmal AF and may provide the basis for a potential expansion of the therapeutic targets of this treatment modality beyond AF.
This is a cross-sectional, non-interventional study, consisting of three study arms, (1) Full Characterization (AIMS-Full), (2) Surgery Arm (AIMS-OR), and (3) Mucus Collection (AIMS-M). Participants will be recruited and enrolled in either AIMS-Full or AIMS-OR (based on participant availability). Participants who complete the initial characterization study (either AIMS-Full or AIMS-OR), may also go on to participate in the AIMS-M arm, which focuses mainly on sample collection. Participants who choose not to participate in either characterization arm are able to enroll directly into AIMS-M for sample collection only.
The study is a prospective, randomized, parallel-design, multicenter trial in patients ≥40 years of age undergoing cataract surgery. Patients who meet all inclusion and no exclusion criteria will be randomized to 1 of 2 treatment groups - A single 5 mcl anterior chamber injection of IBI 10090, 103.4 mcg/mcl dexamethasone, equivalent dexamethasone dose: 517 mcg at the conclusion of cataract surgery or; - Prednisolone acetate ophthalmic suspension 1% eye drops administered 1 drop 4 times daily (QID) for 3 weeks Safety will be assessed by adverse events (AEs), slit lamp biomicroscopy, fundus examination, intraocular pressure (IOP), visual acuity, and specular microscopy endothelial cell count.
The purpose of this investigation is to evaluate how early biomarkers of infection and inflammation perform in identifying patients at risk for poor outcome in sepsis and septic shock.
The purpose of this study is to measure arterial 99mTc-Tilmanocept uptake using single photon emission computed tomography (SPECT/CT) scanning in HIV infected subjects known to have subclinical coronary atherosclerosis as assessed by contrast-enhanced coronary computed tomography angiography (CCTA).
Facioscapulohumeral muscular dystrophy (FSHD) is the second most common muscular dystrophy with approximately 500 patients in Denmark. It is characterized by weakness and wasting of the facial muscles, the muscles in the shoulder region and of the legs. The primary aim of this study is to investigate possible links and order between inflammation and fat infiltration in the muscles in patients with FSHD. Approximately 15 patients with FSHD will be recruited for repeated MRI-scans during a year where the inflammation and fat infiltration in the muscles can be quantified.
Patients with non-traumatic lower limb amputation are characterized by; high age; majority being men; multimorbidity; and high mortality. The patients comorbidities are related to diabetes and cardiovascular disorders such as arteriosclerosis. Major surgery induces a surgical stress response that initiates a catabolic metabolism. Furthermore, the risk of systemic inflammatory response syndrome (SIRS) both before and after amputation is high (3) as the most prominent indication for amputation is gangrene, followed by non-healing or infected wounds. This leads to an impaired immune response and an increased insulin resistance that also includes a cascade of impaired appetite regulation, low dietary intake and reduced nutrient uptake form the intestine which increases inflammation, loss of muscle and risk of severe complications. Among healthy adults with a normal weight a slow speed of eating will result in a low nutritional intake due to faster satiety experience. Low appetite following major surgery is related to the regulation of hormone controlling the appetite. Especially older patients experience variations in appetite that affect their eating pattern such as eating speed and intake. It is therefore reasonable to assume that the speed of eating and the total nutritional intake among older patients, who are exposed to catabolic metabolism, are associated. The hypothesis is that major surgery induces a change in patients' current eating pattern that is measurable and can be identified as a surrogate measurement of the catabolic state that is related to inflammation. Eating Patterns are often described in clinical practice without engaging in nutritional assessment of the patient. Whether the speed of eating is an objective marker of the current nutritional status has not been established. This study investigates patients undergoing lower limb amputation and their nutritional status, eating pattern and inflammation and whether this is linked to the current degree of disease. The purpose is to describe the development in nutritional status before and after amputation and to investigate associations between patients eating pattern and nutritional status to inflammatory and metabolic biomarkers reflecting the degree of disease.
