Filter by:Physical activity (PA) is essential for the prevention and treatment of chronic conditions. Despite its benefits, global physical inactivity is prevalent, contributing to chronic diseases and premature mortality. For patients with chronic kidney disease (CKD) and rheumatoid arthritis (RA), PA is particularly beneficial as it improves endothelial health, reduces cardiovascular risk, diminishes inflammation, and enhances quality of life. Given the chronic inflammation and immune system dysregulation in CKD and RA, PA may mitigate these effects and improve patient outcomes. The primary objective of this study is to evaluate the effects of a personalized aerobic exercise program on cardiovascular risk in patients with CKD or RA. The secondary objectives are to assess the effects on inflammation and immunosenescence; investigate the relationship between inflammation, immunosenescence, and various health outcomes; compare the impacts of chronic PA and PA guidance on cardiovascular risk, disease activity, lifestyle habits, cognitive functions, and quality of life. This study presents an interventional design. A total of 105 subjects are expected to participate in this study, including 45 CKD patients and 45 RA patients. Participants will be stratified by PA level and cardiovascular risk (SCORE 2 scale) and then randomized into three groups: Control Group: 15 CKD and 15 RA patients; Therapeutic Education Group: 15 CKD and 15 RA patients; and Experimental Group: 15 CKD and 15 RA patients. The inclusion criteria are: age > 50 years; diagnosed with CKD or RA; glomerular filtration rate between 45 and 29 ml/min/1.73 m² for CKD; DAS-28 score ≥ 2.6 for RA; medical clearance for PA; informed consent and affiliation with French social security. The exclusion criteria are: unstable corticosteroid therapy or >10 mg prednisone/day; uncontrolled hypertension; pregnancy; cognitive impairment preventing adherence to the program; inability to perform PA; legal incapacity or anticipated poor cooperation; lack of health insurance and participation in an incompatible study. The primary efficacy criterion of this study is changes in endothelial function (macrovascular arterial stiffness) and the secondary efficacy criteria are: endothelial function (microvascular hyperemia test); levels of inflammation and immunity (blood tests); physical activity levels and quality of life (questionnaires); disease-related functional impairment; disease activity and cognitive function. Patient screening will begin with the identification of eligible patients in the Nephrology and Rheumatology departments. Day 0 will be the selection visit for participant information and consent. A week after Day 0, the inclusion visit and initial assessment (arterial stiffness, endothelial function, disease impact, and blood markers for immunosenescence and inflammation, blood pressure, heart rate, PA level, quality of life, and cognitive functions) will be conducted for all patients. Next, only the patients in the experimental group will carry out a 47-minute cycling intermittent exercise session, perceived exertion assessment, and post-exercise reassessment. They will redo the assessments after the exercise. They will have another 16 sessions of supervised exercise by a health professional and a final session identical to the first for reassessment. Patients in the physical activity guidance group will not undertake a physical exercise program but will receive one call per week to discuss the physical activities performed and get answers to their questions on the subject. The control group will continue with their usual lifestyle habits.
The main objectives of PPS3-2 are (i) to describe the dynamics of vascular aging and baroreflex sensitivity 12 to 16 years a part, (ii) to identify their determinants, and (iii) to quantify the subsequent risk of cardiovascular diseases.
Migraine is a debilitating illness and a major cause of disability in the world. It is highly prevalent, especially among women. Vitamin supplementation is a potential therapeutic option for migraines that remains largely under-explored. Several studies have shown that people with migraine tend to have higher arterial stiffness than people without migraine. Vitamin K2 deficiency is an important mediator of arterial stiffness and calcification due to decreased carboxylation of matrix Gla protein (MGP). Supplementation reverses these changes and improves vascular health in patients with end stage renal disease according to previous studies. Therefore, vitamin K2 supplementation could serve a potential role in migraine patients. The purpose of the study is to test the effect of vitamin K2 on decreasing the frequency of migraine attacks and decreasing arterial stiffness. The population will be recruited from the neurology clinic at LAU Medical Center-Rizk Hospital and will constitute of adult patients. They will be randomized to receive either the supplement of vitamin K2 or a placebo for the duration of 6 months. Laboratory tests and arterial stiffness measurements will be done at the beginning, middle, and at the end of the study for comparison.
Background: Augmented Velocity Index (Avi) is a new Doppler index which can potentially be used to assess arterial stiffness. The Avi of common carotid artery is found to be associated with arterial stiffness and have initial correlation with cardiovascular risk factors. Avi can be used in any vessels (superficial or deep vessels) where arterial Doppler waveforms can be obtained. Aims: The aims of this study are to investigate the associations of Avi of hepatic artery, renal artery, central retinal artery and internal carotid artery with arterial stiffness and cardiovascular risk factors in a group of apparently normal subjects. Methods: Recruit 350 subjects with no known medical illness or drug treatment for ultrasound examinations and blood tests. In ultrasound examination, the Avi of carotid arteries, hepatic arteries, renal arteries and retinal arteries are recorded. The carotid-femoral pulse wave velocity is also calculated for the assessment of central aortic stiffness. Other important correlates of arterial stiffness including carotid intima-media thickness, fatty liver status, liver stiffness and abdominal fat thickness are assessed in the ultrasound examination. The clinical and laboratory examinations include anthropometric indexes, plasma glucose level, lipid profile, renal function tests, liver function test, urinary albumin creatinine ratio, blood pressure measurement.
VIKIPEDIA is a multi-centre, placebo-controlled, randomized, open-label intervention clinical trial on Peritoneal Dialysis (PD) patients. At baseline the investigators will recruit End-Stage Renal Disease patients undergoing PD and randomize them to either daily per os supplementation of 1mg menaquinone-7 or placebo for 1.5 year. The investigators will study the effect of vitamin K2 supplementation (through normalization of dp-ucMGP) on arterial stifness and the occurence of cardiovascular events. The investigators will also cosider as secondary endpoints, mortality, central aortic blood pressure and indices of 24h-ambulatory blood pressure.
