This is a multicenter, retrospective, real-world observational study aimed at developing and validating an artificial intelligence-based tool for identifying ulinastatin treatment responders and risk stratification in cardiac surgery patients undergoing cardiopulmonary bypass (CPB). Ulinastatin, a glycoprotein extracted from human urine, has shown potential benefits in reducing postoperative complications and inflammatory responses in cardiac surgery. However, evidence supporting its efficacy and optimal application in specific patient populations remains insufficient. This study will collect clinical data from approximately 4 tertiary cardiac centers in China, including patients who underwent cardiac surgery with CPB. Using machine learning algorithms (such as weighted K-modes clustering and XGBoost), the study aims to: (1) construct a multicenter real-world database for cardiac surgery; (2) identify clinical characteristics associated with ulinastatin treatment response; (3) develop and validate an AI-based risk stratification tool to assist clinical decision-making. This study may provide evidence-based guidance for personalized perioperative anti-inflammatory treatment in cardiac surgery.

Immune-mediated inflammatory diseases are a health burden for approximately seven percent of the population of Western nations. Preliminary data suggest variations in ethnic identity and/or geography influence discrimination experiences and inflammatory response trends. This study investigates how geography, ethnicity, and laboratory manipulation of discrimination experiences affect immune cell function and genomic regulation. Flow cytometry and immune cell stimulation will test monocytes collected from peripheral blood for functional effects. Next-generation transcriptomics and epigenomics will assess genomic and epigenetic mechanisms. The hypothesis is that geography, self-identified race, and ethnicity, interacting with laboratory discrimination conditions during the virtual ballgame Cyberball™, significantly affect immune cell function through genomic and epigenetic mechanisms, with perceived discrimination as a moderating factor on the immune outcomes. The transdisciplinary nature of the proposed study aims to provide valuable insights into differential susceptibility to immune-mediated inflammatory diseases across diverse populations. Uncovering these insights will better inform population-relevant interventions for immune-mediated inflammatory diseases.

Pistachio nuts (Pistacia vera L.) are a nutrient- and energy-dense food, and are a significant source of 15 different micronutrients. In addition to an excellent micronutrient profile, pistachios are a good source of monounsaturated and polyunsaturated fats (linoleic acid, oleic acid, and plant sterols). Pistachios have the lowest amount of total fat, and the highest protein, fiber, and phytosterol content compared to other nuts. They possess a high antioxidant content. Specifically, pistachios have high amounts of lutein, zeaxanthin, and phenolic compounds (e.g., anthocyanins, flavonoids, and proanthocyanidins). These aforementioned compounds are known for their anti-inflammatory effects. Pistachios also have been shown to reduce the risk of cardiovascular disease, metabolic syndrome, and all-cause mortality. The purpose of this study will be to determine the effects of consuming 1.5 ounces of pistachios per day compared to consuming no pistachios per day on inflammatory markers (creatine kinase, C-reactive protein, cortisol, Interleukin-8, tumor necrosis factor-alpha, copper-zinc superoxide dismutase, and glutathione peroxidase concentrations) and lean body mass in women and men, 40 to 60 years of age, who have been recreationally active for at least six months (exercising three to five days per week). It is hypothesized that pistachio consumption will significantly lower inflammatory response and significantly increase lean body mass. This will be a randomized study where participants will first complete a two-week baseline run-in period during which they will consume their typical diet. Following this, participants will be randomized to one of two groups for six months: consuming 1.5 ounces of pistachios per day or a control group (consuming no pistachios). Those consuming pistachios will be in addition to their usual diet. The overall goal of this study is to evaluate the effects of pistachio consumption on inflammatory markers and lean body mass in women and men, 40 to 60 years of age, who exercise three to five days per week. This study could provide a simple, healthy way for recreationally active individuals to decrease inflammation and improve body composition.
NCT07495566
This retrospective observational study aims to evaluate the predictive value of systemic inflammatory markers in determining treatment response in patients with lumbar radicular pain treated with a combination of pulsed radiofrequency (PRF) and transforaminal epidural steroid injection (TFESI). Hematologic indices derived from routine blood tests-including neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), platelet-to-neutrophil ratio (PNR), neutrophil-to-monocyte ratio (NMR), systemic immune-inflammation index (SII), systemic inflammation response index (SIRI), mean platelet volume (MPV), red cell distribution width-standard deviation (RDW-SD), and red cell distribution width-coefficient of variation (RDW-CV) and pain scores assessed using the Numeric Rating Scale (NRS), will be analyzed in relation to treatment success (defined as ≥50% NRS reduction at 4 weeks). Receiver operating characteristic (ROC) analysis will be used to determine optimal cutoff values for significant markers. The study aims to contribute to personalized pain management strategies by identifying accessible biomarkers that may predict treatment outcomes.
NCT03401190
This open-label, dose-response study will evaluate the safety and efficacy of CM4620-IE in patients with acute pancreatitis and accompanying SIRS. The study will consist of two phases. The first phase will consist of 4 female and 4 male patients (cohorts 1 and 2, respectively), enrolled concurrently, randomized in a 3:1 ratio to receive CM4620-IE plus standard of care versus standard of care alone. Planned doses for first phase will be CM4620-IE 1.0 mg/kg on Day 1 and then 1.4 mg/kg on Days 2 - 4. The second phase will consist of 8 female and 8 male patients (cohorts 3 and 4, respectively), enrolled concurrently, randomized in a 3:1 ratio to receive CM4620-IE plus standard of care versus standard of care alone. Planned doses for second phase will be CM4620-IE 2.08 mg/kg on Days 1 and 2 and then 1.6 mg/kg on Days 3 and 4. Dose escalation to second phase would only occur if needed for efficacy reasons and if no events suggesting a safety signal would occur with higher dosing. The study is not powered for the analysis of study data with inferential statisitcs as the primary purpose of the study is to explore what endpoints would be most appropriate for future trials.
NCT05934708
The fluctuating concentrations of female sex hormones, namely estrogen and progesterone may have an effect on the ability of the tissue to withstand challenging exercise conditions, such as eccentric exercise. These sex hormones have also been purported to influence the perceived difficulty of exercise. This study aims to uncover how the different estrogen and progesterone concentrations present throughout the menstrual cycle effect perceived readiness to perform, perceptions of difficulty, and different recovery metrics.

Individuals of Chinese heritage are the largest and fastest growing segment of the US Asian population. US Chinese have sociodemographic characteristics and culture that differ substantially from other US Asians, and therefore, differ in social determinants of health, health status, and disease risk. US Chinese adults are at increased risk for cardiometabolic disease, related conditions (obesity, type 2 diabetes mellitus, hypertension), and systemic inflammation that promotes disease onset and progression. Immigration to a new country can substantially impact the gut microbiome which may promote systemic inflammation. Pilot interventions indicate a high-fiber diet rich in whole grains reduced inflammation and improved obesity. Additionally, the United States Department of Agriculture (USDA) supported, evidence-based HomeStyles intervention has demonstrated feasibility, acceptability, and efficacy in improving lifestyle behaviors and home environments associated with obesity risk in families. A lack of linguistically, culturally tailored interventions to their specific health needs makes it difficult for US Chinese to implement healthy lifestyle behaviors and reduce health risks. Interventions tailored for US Chinese that could attenuate modifiable cardiometabolic risk factors, understand physiological sequelae, and bridge health equity are not currently available. Thus, the overall goal of this project is to test the efficacy of HomeStyles in improving health outcomes in US Chinese. Project aims are to: A) Culturally adapt the HomeStyles intervention through community-engaged approaches. B) Conduct a 10-week, 2-armed Randomized Controlled Trial (RCT) to test HomeStyles intervention efficacy on health outcomes (dietary intake, physical activity, self-efficacy, HbA1C, waist circumference, and BMI), hypothesizing that participants randomized to the treatment condition will have greater improvements in health outcomes than control comparators. C) Examine associations between intervention participation and gut microbiota/systemic inflammation and test hypotheses that a whole-grain rich diet adopted by those in the intervention group will increase anti-inflammatory gut bacteria, reduce inflammatory gut bacteria, and lower systemic inflammation.

Brain tumor surgery is commonly associated with different degrees of preoperative intracranial hypertension and surrounding tumor edema, elicited by tumor underlying pathophysiology. During craniotomy for brain tumor resection maintenance of hemodynamic stability and intracranial homoeostasis is of paramount importance. Disordered hemodynamics or adverse stress may activate the immune inflammation or neuroendocrine responses and lead to a surge of inflammatory mediators and stress hormones, which are implicated in secondary brain insults. Adverse physiological responses caused by intraoperative disordered hemodynamics or surgery-related damage, may lead to some secondary brain injury (such as cerebral edema or cerebral hemorrhage), aggravating damage to brain tissue and affecting the recovery from anesthesia, cognition and prognosis in patients. Prevention of secondary brain injury is a key-endpoint to improve clinical outcomes in glioma patients undergoing craniotomy. Alpha2-adrenoceptor agonists have been widely used for sedation, analgesia and anti-sympathetic actions for many years, but the definite evidence of their potential use as neuroprotectants has so far been confined to animal studies, yet the findings are inconsistent. Dexmedetomidine (DEX) has been demonstrated to be a new type a2 adrenergic receptor (a2-AR) agonist, which can selectively bind with the a1 and a2 adrenergic receptor, and playing a dual role by restraining the activity of sympathetic nervous and stimulating the vagus nerve. Dexmedetomidine (DEX) also plays an important role in in inhibiting inflammatory and neuroendocrine responses. Animal experiments showed that the right must have a dexmedetomidine neuro-protective effect. However, the brain-protective effect of dexmedetomidine in anesthesia of craniotomy resection of glioma has not been reported. Thus, the aim of this study was to explore the effect of dexmedetomidine on perioperative brain protection, as well as cerebral oxygenation and metabolic status aiming to provide a basis for clinical rational drug use in patients undergoing craniotomy resection of glioma.
NCT05459207
The purposes of the study are to quantify and compare relationships among acute changes in inflammatory markers and evoked pain sensitivity after a high-fat meal (HFM) challenge, compared to a moderate-fat meal challenge, and explore the influence of body composition on these responses, in individuals with chronic spinal cord injury
NCT07476391
Systemic inflammatory response syndrome (SIRS) is associated with severe metabolic stress that can lead to rapid breakdown of skeletal muscle and the development of stress-related malnutrition. These processes often result in muscle weakness, delayed recovery, prolonged hospital stay, and increased morbidity and mortality in affected patients. In recent years, increasing attention has been paid to signaling molecules produced by skeletal muscles, known as myokines. Myokines influence not only muscle regeneration and muscle breakdown but also have a wide range of effects on other organs and tissues in the body, including the brain and gastrointestinal tract. Previous studies suggest that lower levels of certain myokines, such as myostatin and irisin, may be associated with worse outcomes in critically ill patients. The primary aim of this prospective observational study is to evaluate the association between the levels of selected myokines and prolonged hospital stay in patients with systemic inflammation. If such an association is confirmed, myokines could potentially serve as prognostic biomarkers for the development of muscle dysfunction and prolonged hospitalization. Secondary objectives include evaluating correlations between myokine levels and other indicators of systemic inflammation and muscle dysfunction. In addition, the study assesses the potential use of bedside ultrasound measurement of the quadriceps muscle to detect muscle catabolism and to help predict clinical outcomes in hospitalized patients.
NCT07452146
The study design consists of a randomized, double-blind, placebo-controlled study of low dose endotoxin. Individuals with current AUD (n=32) and matched controls without AUD (n=32) will be randomly assigned to receive a single intravenous (I.V.) infusion of either low dose endotoxin (0.8 ng/kg of body weight) or placebo (same volume of 0.9% saline solution) to determine the acute and protracted role of inflammation in alcohol use.

The purpose of this study evaluate the relationship between inflammation and epilepsy in neonates with seizures after birth.
NCT03229538
This study's objective is to determine the pharmacokinetics (PK)/pharmacodynamics (PD), safety and efficacy of methylprednisolone in infants undergoing heart surgery with cardiopulmonary bypass. This is a prospective, double blind, multi-center, placebo-controlled safety and efficacy study. Blood samples will be collected from a subset of enrolled study participants to evaluate multiple dose methylprednisolone PK/PD. Participants will be randomized in a 1:1 fashion to intravenous methylprednisolone versus placebo. Study drug/placebo will be administered 8 to 12 hours before the anticipated start time of surgery and in the operating room at the time of initiation of cardiopulmonary bypass. Patients will be followed for primary and secondary outcomes for the duration of their hospitalization. Serious study drug-related adverse events will be collected for 7 days after the last dose of study drug.

The clinical presentation of the ongoing coronavirus disease-19 (COVID-19) pandemic in pregnant women is unique with more asymptomatic infection, higher morbidity when symptomatic, yet without a difference in mortality rate. This is strikingly different from the high mortality observed during the past influenza A pandemics. Though both influenza A virus (IAV) and SARS-CoV-2 are single-stranded RNA viruses, the exquisite vulnerability of pregnant women to influenza A but not COVID-19 remains a mystery. Our objective, therefore, is to determine the mechanisms that predispose pregnant women to severe influenza A but confer protection against SARS-CoV-2 infection by examining the viral entry factors and innate immune response mechanisms in the nasal epithelium of pregnant vs. non-pregnant age-matched women.
NCT05874895
Antimicrobial and supportive therapeutic interventions in patients with septic shock are usually effective - procalcitonin and interleukin-6 levels fall rapidly in most cases, and noradrenaline support can be discontinued within a few days. Unfortunately, only in a small portion of patients, do the organ functions improve at the same time, and in most of them, multi-organ failure persists. Therefore, it is likely that, in addition to infection and the response to infection, other mechanisms are also involved in the persistence of organ failure in patients after septic shock.

Kayaking requires high energy expenditure and optimal metabolic adaptation for performance and recovery. While research on other sports exists, the effects of chocolate milk on kayakers' recovery remain unexplored. Intensive kayaking induces physical stress, necessitating precise energy balance monitoring. This study evaluates metabolic and inflammatory markers, including glucose, glycogen, insulin, creatine kinase (CK), interleukin-6 (IL-6), ghrelin, leptin, peptide YY, peripheral blood morphology, and blood gas parameters to assess fatigue and recovery. Chocolate milk, with its ideal carbohydrate-to-protein ratio, supports glycogen replenishment, muscle repair, hydration, and oxidative stress reduction. Studies suggest it may outperform commercial sports drinks in endurance recovery by limiting muscle damage, inflammation, and improving acid-base balance. Findings will reveal whether chocolate milk enhances energy recovery, reduces muscle damage, and mitigates inflammation, contributing to endurance sports nutrition strategies
NCT06508437
Observational and randomized studies suggest that influenza vaccine may reduce future cardiovascular events in patients with cardiovascular disease. Beyond classical view of indirect effect, linked to the neutralisation of the virus, it is currently considered whether the vaccination may have a direct effect on inflammatory process.Atherosclerosis is known to be driven both by lipid stress and inflammation both at local and systemic level. The investigators suggest that influenza vaccination could have a positive effect on atherosclerosis by regulating plasma inflammation. The aim of this pilot study is therefore to assess the impact of influenza vaccination in patients with stable coronary artery disease on the circulating inflammatory response, in order to validate its potential immunomodulatory effect. If it is found to be beneficial, it could also constitute a future adjuvant therapeutic tool to traditional pharmacotherapy in the prevention of cardiovascular events.

NCT06041581
Cardiovascular disease (CVD) is common, deadly, and costly, and adults with insomnia represent a large group of people at elevated risk of developing CVD in the future. This clinical trial will determine if our updated insomnia treatment, called the SHADES intervention, improves CVD factors thought to explain how insomnia promotes CVD and if these improvements are due to positive changes in sleep factors. A total of 200 primary care patients with insomnia and CVD risk factors will be randomized to 6 months of the SHADES intervention (internet, telephonic, and/or face-to-face cognitive-behavioral therapy for insomnia) or the active control condition (sleep education/hygiene, symptom monitoring, and primary care for insomnia). Before and after treatment, participants will complete measurements of the CVD factors (systemic inflammation, autonomic dysfunction, metabolic dysregulation, proinflammatory gene expression) and the sleep factors (insomnia symptoms, sleep onset latency, wake after sleep onset, sleep efficiency). Researchers will test whether the SHADES intervention produces greater improvements in the CVD factors than the active control condition.
