Modern vascular surgery has various options for open and endovascular surgical methods aimed at treating patients with peripheral arterial diseases. Despite the achievements of vascular surgery, the occurrence of postoperative complications levels out the success of surgical interventions and requires repeated surgical interventions. The most common complication is stenosis of the reconstruction zone, which develops in approximately 50% of operated patients. At present, the apoptosis system plays an equally important role in the development of restenosis of the intervention zone. It has been recognized as a central component in the pathogenesis of atherosclerosis, in which the Bcl-2 family of proteins is activated. It is a group of cellular proteins that are important regulators of the apoptosis system in cells located in the mitochondrial membrane. In experimental animal models, it was shown that apoptosis after angioplasty of the coronary arteries proceeds in the form of two waves. After injury to the vascular wall, during the first hours, it is activated in the smooth muscle cells (SMC) of media, and after two weeks in the cells of the neointima, by the 28th day it almost completely stops. A decrease in the apoptosis index in the postoperative period may cause the development of restenosis of the reconstruction zone. The use of antioxidants, for example, alpha-tocopherol acetate, in the first month of the postoperative period, at the time of activation of apoptosis, inhibits the latter and reduces the proliferative activity of the SMC media and neointima. One month after surgery, delayed apoptosis of vascular wall cells can lead to the development of neointima and restenosis. In this case, the use of drugs that enhance apoptosis, for example, lipophilic statins, calcium channel blockers, will be relevant. Nitric oxide metabolites, depending on the concentration, can act as both an inducer and an inhibitor of apoptosis. The mechanism of NO-induced apoptosis in SMC includes an increase in the Bax / Bcl-2 expression ratio, which leads to the release of cytochrome C from mitochondria, activation of caspase-3 and -9. In patients with atherosclerosis of the peripheral arteries, proteins of the Bcl-2 family and their relationship with markers of endothelial dysfunction have not been sufficiently studied, the results obtained are contradictory.
one-centered, open, non-randomized, controlled clinical trial will focus on a comprehensive study of the clinical, functional and molecular biochemical characteristics of the natural course of COPD in combination with peripheral atherosclerosis
The aim of this study is to investigate whether near-infrared guided percutaneous coronary intervention in patients with acute myocardial infarction provides improved stent strut coverage at six months compared to conventionally angiography guided percutaneous coronary intervention.
This study is designed to evaluate the efficacy of automated electronic alerts in the electronic health record to improve rates of best practices in the treatment of patients with hyperlipidemia who present in the setting of outpatient primary care and family medicine practices within the Yale New Haven Health System.
A pilot study to assess feasibility of methods of an observer-blinded randomised controlled trial of the effect of vitamin D supplementation in Chronic Kidney Disease and low vitamin D levels on markers of vascular function (Flow Mediated Dilatation of Brachial Artery), vascular structure (Carotid Intima Media Thickness) and Immune Regulation (frequencies of CD4+CD28null T lymphocytes ad Regulatory T lymphocytes).
In patients with chronic illness, screening for falls and their health consequences are major public health issues. Muscle weakness, gait and balance disorders are among the most common risk factors for falling. Assessing these parameters would thus be a crucial step in the evaluation of the risk of falling, allowing to more precisely orient the management strategy. Combining inertial unit sensors with clinically validated tests can provide additional information to improve the assessment of fall risks. We therefore propose to constitute a monocentric exploratory study, testing a prognostic screening tool, in patients suffering from a chronic pathology, in order to assess the risk of falling in this population. Considering the relationship between muscle weakness and the risk of falling, we can assume that a deficit in muscle strength will result in less vertical acceleration which could point to a muscle cause of the balance disorder and thus allow a finer detection of the risk of falling. On the other hand, we hypothesize that spinal static disorders in chronic pathologies and in particular osteoarthritis, as well as balance disorders linked to impaired deep sensitivity lead to an increase in oscillations of the trunk when walking which can cause postural balance disorders thus increasing the risk of falling.
This study postulates that the application of Sirolimus, an anti-proliferative agent that inhibits neointimal hyperplasia, via Sirolimus coated balloon (SCB) will be safe and will result in better arterial patency in infrainguinal peripheral arterial disease (PAD). The aim is to evaluate the efficacy (12 month freedom from clinically driven target lesion revascularisation) and safety (freedom from major adverse events) of sirolimus coated balloons in the treatment of infrainguinal PAD.
The investigators will aim to determine the association of mood disorders (MDO) with preclinical and clinical cardiovascular (CVD) risk factors among children. The investigators will also aim to identify traditional and non traditional predictors of CVD risk among children with MDO.
Background: Psoriasis causes chronic inflammation in the body. Researchers want to see if a kind of vitamin B3 dietary supplement can help. This might lead to more treatment options. Objective: To test if the dietary supplement nicotinamide riboside can improve immune system function in the blood and skin of people with mild to moderate psoriasis. Eligibility: People ages 18-80 with mild to moderate active psoriasis not currently treated with biological therapy Design: Participations will be screened with: - Medical and medication history - Physical exam - Measure of body mass index - Skin exam - Blood and urine tests Participants will have visit 1. They will have repeats of the screening tests. They may also have 2 skin biopsies, which are optional. These will be from both lesions and unaffected areas. The areas will be injected with a numbing medicine. A round cutting device will remove small pieces of skin from each area. Participants will take the study supplement or a placebo starting at the first visit. Neither participants nor the study team will know which they receive. Participants will take capsules twice daily for a total of 4 weeks. Participants will then have visit 2. This will include the tests performed at visit 1. Participants may by contacted by phone or email between visits to see how they are doing. If participants develop any side effects in the 7 days after they stop taking the capsules, they may have another visit.
