Filter by:The aim of this study is to develop exercise prescription of TBI patients and then to evaluate the effectiveness of programmed aerobic walking exercise to improve cognitive performance, depression relief, motivation, symptom, resilience and quality of life with improvement of CBF. This will be a randomized controlled clinical trial, using a mixed method to explore the feasibility and validity of such a safety exercise prescription. Then, a randomized clinical control trial will be applied in TBI patients to evaluate the effectiveness of programmed aerobic exercise to promote psysical-psycho-social health such as cognitive status, 6 minutes walk test, depression relief, motivation, symptom, resilience and quality of life.
This is a prospective, observational study designed to evaluate the role of dynamic computed tomographic perfusion (CTP) and Computed Tomography-Derived Fractional Flow Reserve (CT-FFR) in patients presenting with chest discomfort.Patients with lesions greater than 50% and who meet all other inclusion/exclusion criteria will qualify to be a subject in the CTP study /CT-FFR 49. Those who agree to participate will be scheduled to have the CT-FFR and CTP performed within sixty days of the initial Coronary CTA procedure. A CTA will be performed at rest for FFR. The patient will then take approximately a 30 min break. Regadenoson will then be administered and the dynamic CT procedure will be done for perfusion. If patients are deemed to be appropriate for invasive angiography by the referring physician, coronary lesions between 40% and 80% will get a fractional flow measurement performed if indicated on a clinical basis. Stenosis in vessels less than 1.5 mm will be excluded from the study. The CT-FFR and CTP will be performed in these patients within 60 days of index coronary angiography.
This study seeks to determine the effects of a whole-food, plant-based diet on lipid, metabolic, and inflammatory biomarkers. Eligible participants will have had either an LDL-C >100 mg/dL or non-HDL-C >130 mg/dL without a current diagnosis of coronary heart disease and are willing to adhere to a whole food plant based diet for at least 8 weeks. Participants enrolled in the study will provide fasting blood work, complete a baseline quality of life survey, and receive education on a whole-food, plant-based diet at a local Lancaster County grocery store during their first study visit. Throughout the study, patients will have access to dietary counseling which will be provided by a certified nutritionist and will be asked to record and submit daily food diaries. Study participants will be asked to adhere to a whole food plant based diet for a total of 8 weeks. Prior to the final study visit, participants will be asked to obtain follow-up fasting bloodwork around 7 weeks post start of whole food plant based diet. The results, along with a follow-up quality of life survey, and an opportunity to discuss the bloodwork with a doctor will be held at the local grocery story 8 weeks after the first study visit.
The purpose of this retrospective chart review pilot study is to research the results and scores of the QOL questionnaire implemented across Allina Health clinics. This study will investigate average QOL scores by clinical population and demographic group, the change in scores over time, and the effect of clinical interventions on QOL scores. The results will provide insight into QOL trends within different patient populations and provide guidance regarding optimal treatment plans so that Allina caregivers can positively impact patients' QOL.
Rigorous clinical practice assessment is a key factor to improve patient's care and prognosis in interventional cardiology (IC). A multicentric IC observational study (CRAC), fully integrated to usual coronary activity report software, started in Centre Val de Loire (CVL) region in 2014. CRAC observatory was conduced on five IC CathLab of CVL region. Quality of collected data is regularly evaluated and allowed building an exhaustive, and reliable database. This solution could easily be developed in other French regions.
Wide Pulse Pressure is frequently present in the normal, full-term neonatal population. This study will evaluate the frequency and persistence of wide pulse pressure in the neonatal population. Using a prospective study design in the Regular newborn and Observation nurseries of SIUH, North site. Healthy newborns that are between 0-72 hrs of age will have their blood pressures measured using the oscillometric method. This data will offer insight into whether the presence of wide pulse pressure in otherwise healthy newborn infants warrants further cardiovascular evaluation
The American Heart Association (AHA) and American College of Sports Medicine (ASCM) recommend older adults (50≤ age ≤ 80) perform at least 30 minutes of moderate-intensity aerobic exercise on most days ( ≥5 days) of the week. This suggestion arises, in part, from data supporting that regular physical activity reduces the risk of adverse cardiovascular events A portion of these benefits may be from reductions in the incidence and severity of cardiovascular risk factors, including diabetes mellitus, obesity, and hypertension. While this recommendation for physical activity has been in existence for almost 15 years, the rates of obesity in the United States continue to rise and prevalence of sedentarism remains at best unchanged. Researchers have been engaged in investigating novel interventions to designed increase physical activity to reach the recommended activity targets. One promising intervention involves use of inexpensive, easy to use pedometers that allow individuals to objectively track the number of steps taken during a set period of time. Recent data suggest that an average of 10,000 steps/day as measured by a pedometer accurately estimates the activity levels recommended by the AHA, ASCM, and US government public health guidelines. While the benefits of habitual exercise are well-documented, there are no data that demonstrate current recommendations for moderate physical activity in older adults by the ASCM, AHA, and US public health guidelines reduce the risk of adverse cardiovascular events. Interestingly, prior work indicates that pedometer-centered interventions can increase physical activity, suggesting that this type of intervention could potentially lead to cardiovascular benefits. Using validated surrogate markers of cardiovascular risk including brachial artery endothelial function, tonometric measurements of vascular stiffness, and measurements derived from transthoracic echocardiography, we will determine whether increasing the physical activity of sedentary adults to an average of 10,000 steps or more/day translates into improvements in cardiovascular health. This will be determined in the context of a randomized control trial employing a control group, a study group that uses a pedometer alone, and an intervention that couples a pedometer with internet-based motivational messaging software demonstrated in our preliminary data to encourage older adults to reach and exceed the 10,000 steps/day goal.
