Filter by:Biodiversity is essential for nature and human well-being. Land use has reduced biodiversity in cities, which weakens the functionality of the urban ecosystems and the well-being of citizens. This may also increase the risk of immune-mediated disorders among urban dwellers. In Biodiversity interventions for well-being (BIWE), microbial biodiversity interventions are performed to increase biodiversity in urban built areas. Results from the intervention trials are combined with publicly available land cover and ecological data. These are analyzed from the viewpoint of shifts in ecosystems and human well-being and immune regulation, ecological quality, and urban planning. The investigators set up an intervention study in which urban private yards are rewilded with diverse vegetation and decaying deadwood and plant residuals. The investigators aim to evaluate the effect of rewilding, and yard management practices on commensal microbiome, cortisol levels and well-being and salivary cytokine levels, and gene pathways.
The study started after the second COVID-19 vaccination of the participant with blood spots appearing on the skin with severe arthritis. The study continued to the third-dose full vaccination of the participant with the recombined COVID-19 vaccination and afterwards. The study completed until intervention.
The goal of this clinical trial is to explore the role of wheat and corn germ blended oils in regulating oxidative stress and immunomodulation in dyslipidaemic populations, to explore their effects on intestinal flora, antioxidant and immunomodulation. The main questions it aims to answer are: - How does phytosterol-rich wheat corn germ blended oil affect oxidative stress and immune function in dyslipidaemic people compared to peanut oil? - How does phytosterol-rich wheat corn germ blended oil affect serum metabolites, serum fatty acid profile, and intestinal flora in dyslipidaemic populations compared to peanut oil? What are the specific mechanisms involved? Participants will be randomly assigned to the intervention and control groups, the packaging of germ oil and peanut oil will have a uniform appearance, and participants will be instructed to replace their household cooking oils with the distributed cooking oil for three months, in addition to replacing all the canteens in the staff units with the trial oil for more than three months. Participants did not know who was the control oil, germ oil or peanut oil, and both were randomly distributed to different groups of participants by the third-party supervisors. Researchers will compare peanut oil to see if phytosterol-rich germ oil can improve oxidative stress and immune function in dyslipidaemic populations, in addition to exploring possible underlying mechanisms of improvement using multi-omics techniques.
The goal of this clinical trial is to study the effects of stellate ganglion block (SGB) in participants with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). The main questions it aims to answer are: Does SGB treatment improve symptoms of ME/CFS (e.g. brain fog, fatigue)? Do changes in symptoms go along with changes in blood or saliva? Participants will receive a total of six blocks over three weeks (one block on each side, one day apart, per week). Prior to treatment and at two points following treatment, participants will complete surveys, take a cognitive (puzzle type) test, and provide blood and saliva for analysis. Participants will measure their heart rate daily using a free smart phone app.
The main purpose of this study is to assess the safety and efficacy of peresolimab in adult participants with moderately-to-severely active rheumatoid arthritis.
The investigators will study if group education for parents of adolescents with type 1 diabetes (T1D) will improve the transition from adolescence to adulthood. The investigators aim to conduct a pilot randomized controlled trial (RCT) of parent group education sessions to assess the feasibility and refine the intervention to inform a full-scale multicenter RCT. The aims of the pilot are to estimate: 1. Recruitment rate, 2. Adherence rate, 3. Response rate, and 4. Retention rate. The aims for the future full-scale multicenter RCT are to assess the effect of parent group education sessions integrated into pediatric care, compared with usual care on self-management, hemoglobin A1c (HbA1c), adverse outcomes and validated measures during the transition from adolescence to adulthood. The investigators will conduct a parallel group, blinded (outcome assessors, data analysts), superiority pilot RCT of parents and their adolescents with T1D (14-16 years of age) followed at a university teaching hospital-based pediatric diabetes clinic in Montreal. Interventions will occur over 12-months. Follow-up will be to 18 months from enrollment.
The mechanisms underlying POTS are not well understood. Though heterogeneous in nature, patients often present with symptoms that include fatigue, orthostatic lightheadedness and tachycardia, "brain fog", shortness of breath, and sleep disruption. The central mediator that links observations in disease entities similar to POTS is energy use and balance driven by mitochondrial health. Mitochondrial dysfunction (i.e. respiration defects, reactive oxygen species (ROS) generation, and structural abnormalities) are hallmarks of currently defined syndromes that resemble POTS symptomatology. Many patients with POTS have underlying immune system dysfunction, which, when treated, may improve the patient's overall health. Though autoimmunity has been demonstrated in POTS, overall immune dysregulation may be broader and include immune cell exhaustion and persistent inflammatory cytokine responses. Immune dysfunction including cellular exhaustion and persistent inflammation has been linked to mitochondrial function. Therefore, we hypothesize that a unifying feature of POTS results from latent or continued mitochondrial/immune dysfunction which then impacts multi-organ energy imbalance and immune homeostasis. Understanding and targeting mitochondria utilizing established, novel, and directed approaches including time-restricted eating (TRE) will help to unravel common etiologies and help us to better diagnose, manage, and treat POTS.
COVID-19 pandemic has made a tremendous impact on Indonesian economic and health care system especially with the double burden of diseases facing by Indonesia as a developing country. The prevalence of non-communicable diseases such as obesity, type diabetes, and cardiovascular diseases is increasing. These diseases along with older age have been known as an established risk factors for higher mortality and severe clinical disease entity in COVID-19 infection. Although, there is still some part of patients with these co-morbidities that only present with mild symptoms when infected with SARS-CoV-2, even for some without any symptoms. Thus, it would be very interesting to evaluate how are these role of aging and cardiometabolic parameters in the clinical disease course of COVID-19 infection, and how are the relationship with the immune system.
To determine the nephroprotective potential of treatment with sparsentan in patients newly-diagnosed with immunoglobulin A nephropathy (IgAN) (ie, incident patients) who have not received prior angiotensin-converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB) therapy.
This study is a Phase 1 / 2 trial to determine the safety and efficacy of CYNK-001, an immunotherapy containing Natural Killer (NK) cells derived from human placental CD34+ cells and culture-expanded, in patients with moderate COVID-19 disease.
