Filter by:Gallium-68-DOTATOC binds primarily with high affinity to somatostatin subtype 2 (SSTR2) receptors and these somatostatin receptors are also overexpressed on inflammation cells when activated. The hypothesis is that the GATED mode on a Gallium-68-DOTATOC cardiac recording would be able to highlight abnormalities that could be correlated with the age of the patients and their cardiovascular risk factors.
The goal of this prospective, diagnostic observational study is to learn about how imaging based markers for components of liver disease appear in children with obesity. It aims to determine whether the imaging markers (ultrasound and MRI) for liver disease can be tools to improve diagnostics for liver affection in children with obesity and to ascertain how the markers are related to multiple clinical measures, for example BMI and serology measure, and treatment effects over time.
People with axial spondyloarthritis (axSpA) often have intestinal inflammation and intestinal microbiome dysbiosis, with some similarities to Crohn's-like inflammatory bowel disease (IBD) gut inflammation. However, research has not addressed whether Partial Enteral Nutrition (PEN), a diet formed of a liquid formula and some solid whole foods, which is effective at inducing remission in IBD, may influence the dysbiotic microbiome and inflamed, hyperpermeable intestine of axSpA patients, and whether these changes may be accompanied by alterations in systemic markers of inflammation. Thus, there is a need to determine the effects of PEN on these aspects in axSpA patients. In this study, the investigators intend to trial a 2-week course (with optional additional 2-week extension) of a PEN diet in people with active axSpA disease. A group of healthy volunteers following the same diet will act as a control.
The overall purpose of this study is to understand the role of disrupted sleep in the association of exposure to early life adversity (adverse childhood experiences (ACEs)) with vascular endothelial (dys)function. In Aim 1 (The Iowa ACEs and Sleep Cohort Study), the investigators will utilize a cross-sectional cohort design with a state-of-the-art translational approach. Participants will be recruited to objectively characterize the degree to which lower sleep quality and quantity contribute to ACEs-related endothelial dysfunction, inflammation, and oxidative stress in young adults using: 1. rigorous at home sleep monitoring using 7-nights of wrist actigraphy and 2 nights of home-based polysomnography to objectively measure sleep quality (sleep efficiency, wakefulness after sleep onset and sleep depth), and total sleep duration, 2. in vivo assessment of endothelial function via flow-mediated dilation testing, and 3. in vitro determination of endothelial cell inflammation and oxidative stress from biopsied endothelial cells. This study to achieve this Aim. In Aim 2, approximately 70 eligible participants from Aim 1 (The Iowa ACEs and Sleep Cohort Study) will then be randomized to either a 6-week behavioral sleep intervention (cognitive behavioral therapy for insomnia) or a wait-list control to determine the mechanistic contribution of sleep disruption to vascular dysfunction in young adults with moderate-to-high exposure to adverse childhood experiences (ACEs). Following the intervention, participants will again complete: 1. rigorous at home sleep monitoring using 7-nights of wrist actigraphy and 2 nights of home-based polysomnography to objectively measure sleep quality (sleep efficiency, wakefulness after sleep onset and sleep depth), and total sleep duration, 2. in vivo assessment of endothelial function via flow-mediated dilation testing, and 3. in vitro determination of endothelial cell inflammation and oxidative stress from biopsied endothelial cells.
Objectives: Variability of clinical phenotypes in childhood obstructive sleep apnoea (OSA) has prompted research for biomarkers to identify patients at risk of developing OSA-related complications. Upper airway inflammation is documented in children with OSA. Whether it is related to end-organ morbidities and systemic inflammation is under-explored. The primary objectives of our study are 1)To evaluate inflammatory biomarkers with the use of nasal epithelial lining fluid (NELF) collected by nasal strips as a representation of upper airway inflammation in children with OSA compared to non-OSA controls; 2) To evaluate the associations between NELF biomarkers with ambulatory blood pressure (ABP) outcomes in children with OSA. Hypothesis to be tested: Inflammatory biomarkers in NELF in children with OSA are altered when compared with non-OSA controls and correlated with ABP outcomes. Design and subjects: A prospective case-control study. Non-obese Chinese children aged 6-11 years old with habitual snoring (≥3 nights per week) and polysomnography (PSG) confirmed OSA (OAHI of ≥1/hour) will be recruited as cases. Non-OSA children with OAHI < 1 event/h will be recruited as controls. All subjects will undergo evaluation including questionnaires, anthropometric measurements, PSG, 24-hour ABP measurement, blood and NELF sampling. Primary outcome measure: Profile of inflammatory biomarkers in the NELF. Analysis: Correlations between NELF inflammatory biomarkers with polysomnographic and ABP measurements will be evaluated by regression analysis. Expected results: This study will provide novel and important information regarding upper airway inflammatory biomarkers in children with OSA and their relationship with blood pressure outcomes.
The goal of this observational study is to learn about the relationship between serum Galectin-3 levels and subclinical inflammation in patients with Familial Mediterranean Fever (FMF). The main questions it aims to answer are: - Are serum Galectin-3 levels higher in FMF patients compared to healthy controls? - Is there a positive correlation between serum Galectin-3 levels and Serum Amyloid A (SAA) protein levels in FMF patients? Participants will: - Provide blood samples to measure serum Galectin-3 and SAA levels. - Complete a sociodemographic and clinical data form. - Fill out the FMF Quality of Life (QoL) scale. Researchers will compare FMF patients and healthy controls to see if there are significant differences in serum Galectin-3 levels and to determine the correlation between Galectin-3 and SAA protein levels in FMF patients.
The primary objective of this clinical trial is to ievaluate the effect of semaglutide (GLP-1 receptor agonist) in reducing intensity of gastrointestinal (GI) mucositis in patients undergoing high-dosage chemotherapy followed by autologous (auto) haematopoietic stem cell transplantation (HSCT). The secondary objective is to evaluate the effect and safety of semaglutide in reducing gut barrier injury and systemic inflammation in patients undergoing auto-HSCT. Study design: The study is designed as a randomized, double-blind, placebo-controlled, phase 2, two-centre investigator-initiated clinical study. Patients referred for treatment with high-dose chemotherapy and auto-HSCT will be randomized in a 1:1 manner to receive either semaglutide or placebo. The study includes a run-in period 3 to 4-week low-dose period with semaglutide subcutaneously (s.c.) 0.25 mg once-weekly (QW) prior to high-dose chemotherapy treatment followed by a period of 4 to 5 weeks with semaglutide 0.5 mg QW. Total duration of treatment with investigational drug will be 8 weeks. Total study duration for the individual patients will be 20-22 weeks, including a 2-4-week screening period and 10 weeks of follow-up. Study population: A planned total number of 40 patients will be randomized.

The patient will be monitored for safety and measured as per the study protocol until day 180.
Around 10% of patients with myocardial infarction (MI) present with nonobstructive coronary arteries (MINOCA) which pathophysiology is often uncertain. The aim of the study is to evaluate inflammation and endothelial dysfunction biomarkers in MINOCA patients during both acute and stable phases, comparing them with those with MI and obstructive coronary arteries (MICAD).
The involvement of the kidneys in patients infected with the SARS-CoV-2 virus at the outset of the pandemic was associated with high mortality rates worldwide. This was in part due to the generation of an inflammatory process and exacerbated oxidative stress. The present study was initiated to investigate the relationship between morphofunctional changes and gene expression in the kidney tissue of deceased Mexican patients prior to the initiation of vaccination. The investigator designed a single-center, prospective, cohort study, to analyze and relate the morphofunctional changes and gene expression of inflammatory and oxidative stress molecules in the kidney tissue of men who died from severe COVID-19. A total of 40 percutaneous renal biopsies from deceased patients with SARS-CoV-2 infection were included in the study and divided into two a groups. One group was preserved in trizol to obtain RNA and total protein, while the remaining sample was fixed in formalin to be examined by staining with hematoxylin and eosin. The histopathological analysis was conducted by an experienced nephropathologist. The expression of molecules was evaluated by real-time PCR (nphs2, slc9a1, cx3cl1, havcr1, slc22a17, sod2, egf, timp2, hmox1, fabp1, and so forth). The following biomarkers were analyzed: IL-6, Arg-1, DPP4, GSTT1, GGT1, OCL, CYP3A4, and CL-8. Additionally, Western blot analysis was conducted on claudins-5, occludin, HSP70, NRF-2, SOD2, NQO1, γ-GCL, and RAGE. The estimated glomerular filtration rate (eGFR) was calculated using the CKD-EPI (2021) equation, with the subjects divided into two groups based on their eGFR: >60 or <60 ml/min/1.73 m². The statistical analysis was conducted using the Stata program and GraphPad Prism software.
