Filter by:The ENLIGHTEN PAD Trial will collect preliminary data to test whether daily 660 nm light treatment of the lower extremities immediately before home-based walking exercise sessions improves six-minute walk distance at 4-month follow-up, compared to sham light, in people with lower extremity peripheral artery disease (PAD).
The investigators propose a pilot randomized trial to gather preliminary data to test the hypothesis that Fisetin will reduce abundance of senescent cells in blood, skeletal muscle, and both subcutaneous and inter muscular adipose tissue and improve 6-minute walk distance in 34 people with PAD. the investigators will determine whether greater declines in abundance of cells with senescent markers are associated with greater improvement in 6-minute walk distance in people with PAD. In exploratory analyses, the investigators will assess whether Fisetin reduces SASP and novel senescent markers in adipose tissue, muscle, and/or blood.
The purpose of this study is to compare and evaluate a faster MR image that has been optimized to look at participants blood vessel walls.
The objective of the proposed study is to define independent parameters for the diagnostic assessment of the perfusion situation of the gluteal muscle based on multispectral optoacoustic tomography (MSOT) in patients with gluteal claudication in Fontaine stage II (intermittent claudication) pre and post-intervention.
1) The purpose of this study is to test the effects of leg exercise assistive paddling (LEAP) therapy during prolonged sitting (PS) on vascular and functional performance in those with peripheral artery disease (PAD) and age-matched controls. LEAP therapy is a novel application of passive limb movement to enhance blood flow through the legs without muscular contractions. Specifically, LEAP therapy is the rotational passive movement of the lower leg about the knee from 90 to 180 degrees of rotation at a cadence of 1Hz. Previous literature has indicated that this movement pattern can produce robust increases in blood flow in the passively moved limb in healthy individuals, and passive limb movement may protect vascular function during PS. However, the impact of LEAP therapy to improve blood flow in the legs of those with PAD during PS is unknown. 2) To be eligible for this study, those with PAD must be between the ages of 50-85 years, women must be postmenopausal, must have a history of exercise-limiting claudication, have an ankle brachial index (ABI) 0.9. 3) Subjects will participate in a randomized cross-over design study with 2 visits (LEAP therapy and no LEAP therapy). For the first visit, subjects will be randomly allocated to receive LEAP therapy during 2.5 hours of PS or not. For the second visit, subjects will sit for 2.5 hours and will receive the condition that they did not previously receive. Before and after PS, the following measurements will be made: flow-mediated dilation of the popliteal and brachial arteries, arterial stiffness with tonometry techniques, microvascular vasodilatory capacity and skeletal muscle metabolic rate with near-infrared spectroscopy, autonomic nervous system function, and there will be blood drawn from the antecubital vein. After PS, subjects will participate in a graded exercise test to assess functional walking capacity. Finally, during PS, near-infrared spectroscopy on the calf muscles and electrocardiogram will be collected continuously to monitor muscle oxygen availability and autonomic activity, respectively. 4) There will be no follow-up.
The investigators aim to study the effect of SOT in Swiss residents with pulmonary vascular diseases (PVD) defined as pulmonary arterial hypertension (PAH) or chronic thromboembolic pulmonary hypertension (CTEPH).
The study is aimed at assessing the dynamics of changes in biochemical markers of venous wall remodeling (type 1 plasminogen activation inhibitor (PAI-1), fibronectin (fibronectin, FN), vimentin (vimentin, VM), von Willebrand factor (vWF), PECAM-1 (CD31) ) in patients with C2s-C3s varicose veins compared with healthy volunteers while taking Venarus® (diosmin in combination with hesperidin).
Objective: To assess the clinical efficacy of different compression methods within 48 hours after endovenous radiofrequency ablation (RFA) in terms of great saphenous vein closure rate, postoperative complications, quality of life, time to return to normal work, and patient satisfaction.
THE PROBLEM: Patient Reported Experience Measures (PREMs) ask patients about their healthcare service experience. It gives them a voice to share their views. PREMs allow healthcare providers (HCPs) to see where care is good, and where they could improve. Vascular surgery is a surgical speciality looking after people's blood vessels (arteries and veins). There is no PREM available for vascular patients. The research team want to create a PREM for this patient group. WHY IT IS IMPORTANT: A PREM allows HCPs to record and understand patients' experiences of their treatment. It gives patients a way to provide feedback on their healthcare experience. PREMs can help HCPs make changes to patients' care, identifying areas of good practice and areas for improvement. The Welsh Government is keen to support the use of PREMs. AIMS: To develop a PREM specific to vascular surgery patients. RESEARCH PLAN: The research team will summarise the literature about PREMs in surgery. The research team will then run focus groups and interviews with patients and staff to create a 'draft' PREM for vascular patients in Wales. The 'draft' PREM will be translated into Welsh. In the second phase, a larger number of vascular patients (100-300 depending on how long the 'draft' PREM is) from hospitals across Wales will complete the questionnaire. Statistical tests will look at the results to see if the questionnaire works well to capture patients' experiences. Based on these results, small changes will be made to make the 'draft' PREM better. This will make sure the 'final PREM' is ready for widespread use in Wales and beyond. PATIENT AND PUBLIC INVOLVEMENT: The patients' experience team at CAVUHB has reviewed our patients' materials. Our research team includes PPI co-applicants (DC and AH). DC a double amputee who has had many vascular operations. DC has experience raising awareness about vascular disease through public forums like the Limbless Association Charity and BBC Radio Wales. AH has issues with her leg due to smoking and had a keyhole operation to help with that. She had some problems after the procedure This is her first time as a PPI representative. DC and AH supported our research design and will be steering group members. Also, our research focuses on giving patients a voice and will include patients across Wales. A diverse group of patients will be involved across all stages of the PREM development.
The purpose of this pilot study is to evaluate different imaging parameters in patients with previously treatment-naive DME and ME due to RVO before and after treatment with dexamethasone implant, in order to find specific retinal inflammatory and microvascular biomarkers that may be predictive of treatment outcome.
