Active clinical trials for "Inflammation"

This research study will test the effects of macadamia nuts on adiposity, and traditional and emergent risk factors of cardiometabolic disease in adult men and women

The goal of this project is to elucidate interactions between the gut microbiome, anti-inflammatory/anti-oxidant food metabolomic signatures, and human inflammation phenotypes. Inflammation plays both direct and indirect roles in the development of type 2 diabetes (T2D), atherogenic cardiovascular diseases, and other causes of morbidity and mortality. Aronia melanocarpa (Aronia berries) are rich in bioactive polyphenolic compounds, which have been shown to lower inflammation and favorably impact metabolism. However, there is tremendous inter-individual variability in the bioavailability of polyphenolics and production of bioactive phenolic metabolites in the colon that depends, at least in part, on digestive metabolism by the gut microbiota. Little is known about the complex interactions among the gut microbiome, anti-inflammatory food metabolomic signatures, and human inflammation phenotypes. This study will utilize a systems-level approach to disentangle these complex interactions. The specific study objectives are as follows: to determine the impact of Aronia supplementation on inflammation, metabolic health, and gut microbiome composition to determine the static and dynamic metabolomic signature of Aronia based on an Aronia supplementation period and responses to a high-fat meal challenge

The aim of this project is to evaluate daily intake of eggshell membrane taken as supplement (capsule), will reduce markers of inflammation in older people.

Benign prostate hypertrophy (BPH) and inflammation are common non-cancerous enlargement of the prostate, which result in urinary interference and incomplete drainage of the bladder. Compression of the urethra is common cause of such resistance of full draining, and may over time result in progressive hypertrophy, instability, urgency, nocturia and weakness of the bladder musculature. Prostatic growth frequently begins in the 30s, and it is estimated that 50% of all males have benign enlargement leading to 75% by age 80. BPH and low grade inflammation is one of the ten most prominent and costly disorders in males over 50. Urinary tract symptoms are divided into issues of storage, voiding, and post-void symptoms can be associated with bladder outlet obstruction (BOO). This study utilizes isolation of adipose-derived stem/stromal cellular stromal vascular fraction (AD-cSVF) deployed as an IV suspension in sterile Normal Saline (500cc). Due to the anti-inflammatory and immunomodulatory effects common to AD-cSVF are tested in relief of the inflammatory elements and the concurrent hypertrophy in BPH. Early pilot use has suggested a positive effect on these issues, and have relieved much of the incomplete voiding, pain, nocturia, delay in starting/stopping urination, and increased urgency and frequency. Lipoharvesting of Adipose-Derived tissue stromal vascular fraction (AD-tSVF) is now a common closed access to subdermal adipose stromal/stem cell population consisting of both stem and stromal cells, each of which are felt to contribute a wide variety of effects and potentials. Closed, sterile isolation of the AD-cSVF is possible with advent of closed systems to enzymatically release these cells from the actual matrix (scaffolding) within the adipose tissue complex (ATC). This group of largely un-designated cell population is isolated and concentrated via a standard gradient layer separation by centrifugation. This cellular isolate is then suspended in an IV of 500 cc Normal Saline and reintroduced to the patient. This study is examining the clinical safety and efficacy of this approach, as well as tracking the duration of effects and establish a therapeutic interval.

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 aim of this study is to evaluate the effect of acupuncture on inflammation and immune function after craniotomy. This study will be a single-center, parallel group clinical trial that will be conducted at Kyung Hee University Hospital at Gangdong, Seoul, Korea.

Diets containing excessive salt (>12 g/day) have negative effects on kidney and cardiovascular system. Considering this known fact, the investigators aimed to study if the amount of the water taken with excessive salt had any part on these negative effects by testing the blood pressure, serum osmolality, endothelial functions, cardiac function, inflammatory parameters and sympathetic nervous system. Excessive dietary salt raises the serum osmolality, which triggers the protection mechanisms of the body. The first mechanism is the secretion of vasopressin from posterior pituitary and the second one is the polyol mediated aldose reductase enzyme activation in renal tubules. In the beginning, water and a little amount of salt is reabsorbed from the kidneys for keeping the serum osmolality in normal ranges by the elevation of vasopressin. Besides the high levels of vasopressin for long durations may have a role in both developments of hypertension and the progression/development of chronic kidney disease. Polyol mediated aldose reductase enzyme turns glucose into sorbitol, which is turned to fructose by sorbitol dehydrogenase activity. Fructose is degraded by fructokinase activity into toxic substances. With this pathway, the acute energy need is satisfied, yet uric acid, local oxidative stress, and inflammatory mediators rise while nitric oxide levels decreasing. These facts are independent risk factors for both kidney disease progression and hypertension. In addition, excessive salt intake may elevate the transforming growth factor beta-1 (TGF-B1) levels, which activates the sympathetic system, inflammation, and endothelial dysfunction. According to these data, the investigators speculate that if they increase the amount of water intake while eating the high salt diet they may decrease the toxic effect of salt with less increase in serum osmolarity. To test this hypothesis, by regulating the salt and water amount in healthy people's diets, the investigators aimed to evaluate the following these parameters; biochemical parameters that could affect the blood and urine osmolality, blood pressure, vascular endothelial functions with the non-invasive flow-mediated dilatation technique and arterial stiffness, systolic and diastolic functions of the heart by transthoracic echocardiography. In addition, it was planned to evaluate the hormonal effects of arginine vasopressin, a long peptide with 39 amino acids, which is longer and easier to measure than vasopressin levels in serum by measuring the pituitary hormone-derived copeptin. Although, decreasing the salt intake is the first step of the treatment in hypertension, and kidney diseases, the compliance rate to less sodium intake is very low (<20%). The investigators aim is to evaluate the effects of water, which is taken acutely with the excessive salt intake on cardiovascular system and kidney. The findings of the study will important for public health. If the investigators prove their hypothesis, they may recommend increasing high water intake before feeling thirst of which may contribute to decreasing the prevalence of hypertension and kidney disease.
