Filter by:Inorganic nitrate can protect blood vessels from the damage that occurs during cardiovascular disease. Early experimental work suggests that nitrate-induced improvements in vascular function relate to the suppression of inflammatory pathways. Whether this protection against inflammation-induced damage to the blood vessel wall might also be functional in the setting of COVID-19 vaccination will be investigated. Vascular function will be assessed before and after the healthy participant has received their COVID-19-vaccination. Whether there might be differences in the response to the vaccine between the sexes and whether a dietary nitrate intervention impacts upon the effects of vaccination will be investigated. The study is in two parts: Part A: To assess sex differences in the vascular response to COVID-19 vaccination. Part B: To assess whether inorganic nitrate, in the form of dietary inorganic nitrate supplementation compared to placebo control, can raise circulating plasma nitrite levels and thereby prevent the systemic inflammation that causes vascular dysfunction.
The purpose of this project is to determine whether regular consumption of fermented vegetables can decrease inflammation and change the types of bacteria that are normally present in the large intestine. Recent research studies have linked the gut bacteria to many disorders and conditions, such as obesity, cardiovascular disease, diabetes, etc. We also know that certain bacteria are considered probiotic bacteria because they contribute to a healthy gut, while others have been associated with inflammation and disease. Fermented foods may contain beneficial bacteria that may improve health in humans. However, there is a lack of research studies examining the effects of regular consumption of fermented foods on health. This study will help investigators better understand if regular consumption of fermented vegetables can improve inflammation and change the gut bacteria towards a more beneficial profile.
Swallowing difficulty (dysphagia) is a common postoperative complication in patients who undergo cardiac surgical procedures. Postoperative dysphagia in cardiac surgical patients is associated with negative health-related outcomes including increased rates of pneumonia, reintubation, and death as well as increased length of hospital stay and costs of care. This study will examine the safety, feasibility, and impact of preoperative respiratory strength training (RST) on swallowing and associated health-related outcomes in cardiac surgical patients. We hypothesize that preoperative RST will be safe, well-tolerated, and lead to improved swallowing and health-related outcomes in cardiac surgical patients.
- Purpose of the study This study aimed to investigate electrocardiogram measurement and subthreshold low-level autonomic nerve stimulation using external auditory canal electrodes among healthy adult participants - Study design Prospective, single-center, interventional, single-arm design - Study participants A total of 12 healthy adult participants without cardiovascular diseases will be recruited. - Study methods 1. Participant enrollment Study participants will be recruited by advertisement posters announced at the lobby of the hospital 2. Evaluation of electrocardiogram measurement from external auditory canal electrodes Participants are required to attach specially designed external auditory canal electrodes to their both ears to record electrocardiogram. Both electrocardiogram from the precordium and the ear would be simultaneously recorded and compared. 3. Evaluation of low-level autonomic nerve stimulation using external auditory canal Using the electrodes described above, Arnold's nerve will be stimulated with low-level electric impulses using TENS device. During and after the stimulation, heart rate variability will be measured to investigate the impact of nerve stimulation on autonomic function modulation on the heart.
The purpose of this study is to demonstrate whether Behavioral Activation for depression delivered via home based telehealth (BA-HT) is effective in improving social and role functioning in Veterans recently discharged from Cardiovascular disease (CVD-related) inpatient care. Eligible participants will receive either (1) twelve sessions of BA-HT or (2) standard best practices post CVD hospitalization care. Study participants will be 132 Veterans discharged from the Ralph H. Johnson VA Medical Center inpatient care facilities with CVD diagnoses corresponding to ICD 10 codes I20-I25 (120 unstable angina, stable angina; 121 NSTEMI, STEMI, initial encounter; 122 NSTEMI, STEMI, subsequent encounter; 124 acute coronary syndrome; 125 coronary arteriosclerosis with angina). They will be male or female, age 21 and above, and with approximately 40-50% minority representation. There will be assessment at baseline, 1 week post treatment, as well as 3 and 9-months post treatment. The investigators predict that BA-HT will more effectively increase social role and activity functioning, activity, mood and reduce 9-month re-hospitalization compared to current best-practices post-discharge care among patients scoring at least moderately depressed on the PROMIS Depression scale one week following hospital discharge for a CVD event.
The main objective of this prospective cohort study is to assess arrhythmia burden and glycemic variability in a multicenter cohort of patients with end-stage renal disease using a sufficient observation period in order to identify arrhythmia burden and type and characterize associations with patient characteristics and dialysis treatment, glycemic variability and subsequent risk of adverse outcomes.
The present randomised controlled trial aimed to investigate the effectiveness of a clinical decision support system (CDSS) in assisting clinicians to apply nutritional care to breast cancer (BC) patients during the COVID-19 pandemic in Greece. Adult BC women (stages I-IIIA) who underwent mastectomy followed by hormone therapy were randomly assigned either to the Control group, receiving general nutritional advice, or the Intervention (or CDSS) group, in whom a personalised nutritional programme based on the Mediterranean diet together with physical activity guidelines were provided, all produced by CDSS. Medical and dietary history, anthropometrics, biochemical indices and quality of life characteristics were assessed both at baseline and at the end of the study (3 months).
This pilot trial aims to evaluate the feasibility and effectiveness of a technology-based intervention for cognitive-motor training in rehabilitation clinics with geriatric, neurological and cardiac patients. The primary objective of this pilot study is to evaluate the feasibility of exergame-based cognitive-motor training in in-patient rehabilitation settings. The secondary objective of this pilot trial is to evaluate the effectiveness of an expanded rehabilitation treatment (combining exergame training with conventional care) on physical and cognitive functioning in different patient groups.
This study will test the impact of vegetable oils with contrasting fatty acids composition on biomarkers of health (cardiovascular, kidney diseases and diabetes) after twelve weeks supplementation. We will use sunflower oil (high in PUFAs), rapeseed oil (high in MUFAs, locally produced) and a non-intervention control. We have developed a sensitive and selective urinary proteomic biomarker of cardiovascular disease which we will use in a double-blinded randomised study.
The aim of this study is to screen patients with type 2 diabetes with high risk of cardiovascular disease, and intervene with or without Glucagon like peptide-1 receptor agonists.
