15 Clinical Trials for Various Conditions
This is a double-blind, randomized, 12-week parallel study that aims to determine the effects of a cognitive nutritional supplement for 12 weeks on cognition parameters specific to attention/focus related domains, compared to a placebo control, in a general population of adult men and women in the United States.
This is a prospective, single-arm, observational study capturing data from whole-body magnetic resonance imagining (WB-MRI) from up to 100,000 male and female subjects 18 years of age or older recruited at multiple clinical sites within the United States. Study subjects must meet a set of inclusion and exclusion criteria. Potential subjects arriving at the study sites will be evaluated for enrollment. It is the Principal Investigator's (PI) responsibility to enroll only subjects who satisfy the inclusion/exclusion criteria. Recruitment can occur by subject presentation at the sites for elective standard screening, word-of-mouth, flyers, healthcare professional (HCP) referrals, advertisement online, or any other means, subject to approval by the associated institutional review board (IRB) or ethics committee (EC) when applicable.
This project will evaluate the usefulness of Monocyte Distribution Width (MDW) for the diagnosis of blood culture positivity (BSI) in patients in the Emergency Department (ED) and reevaluate the usefulness of MDW in patients with BSI and sepsis. Consequently, if MDW indicate a high likelihood of bacteremia antibiotic management in patients with suspected bacterial infections will be changed and aid appropriate antibiotic administration.
The investigators are aiming to investigate the association between ejection fraction (EF) determined by echocardiography and signals obtained from Photoplethysmography (PPG) in the general population. The investigators are also aiming to investigate the association between blood pressure and signals obtained from PPG in the general population. Finally, the investigators are also aiming to investigate the association between signals obtained from PPG in the general population to cardioechographic findings such as, valvular heart disease, structural heart diseases, cardiomyopathies, pericardial disease etc.
Central sleep apnea (CSA) is a common condition and its treatment remains elusive. The focus of this proposal is to identify the role of the physiologic path involving cortical arousals in CSA by decreasing arousal frequency using the pharmacological agent zolpidem. The goal is to identify the acute effects of administering zolpidem on sleep and respiratory outcomes, and subsequently, its effect on the severity of CSA and propensity to develop CSA. This study will shed light on the mechanisms underlying CSA that involve cortical arousals and will guide future therapeutic interventions for CSA.
In partnership with Helmsley Charitable Trust, the Sanford PLEDGE Study is a large-scale, observational, feasibility study of general population screening for T1D and celiac autoantibodies. Screening is incorporated into routine health care visits within an integrated health system.
The goal of the study is to assess the usability and satisfaction of an electronic patient reported outcomes (e-PRO) mobile application. The secondary aim is to assess and compare response rates between two study groups (e-PRO group vs REDCap survey group). A potential differentiating factor between delivering surveys via smart phone and other electronic modes of delivery is the perceived advantage of being able to conveniently complete survey questionnaires at any time and any location. This could help address certain limitations of the quantitative survey method such as recall bias. Furthermore, the portability, connectivity and ubiquity of smartphones may reduce the amount of training or instructions required for users to complete a survey questionnaire on a smartphone.
The purpose of this study is to use an investigational assay to assess levels of putative biomarkers of traumatic brain injury (TBI) in a general population. The data will be used in a correlative analysis with data collected under a separate study of severe TBI.
The purpose of this study is to collect data to develop and evaluate the use of state-of-the-art machine learning approaches within a mobile phone application for the estimation of blood pressure.
A recent review indicated that sedentary behavior has been associated with increased morbidity and mortality but the intervention studies frequently focus only on changing sedentary behavior (reducing sedentary time) without measuring health-associated outcomes. Elevated cortisol (related to stress) has been linked with health risks. Improved physical fitness has been linked with improved cortisol responses to psychosocial stressors. In addition, increased physical activity induced favorable effects upon low density lipoprotein, high density lipoprotein, and total cholesterol. Previous study also indicated that increasing daily steps have positive effect on blood glucose in people with impaired glucose tolerance. Ultimately, the investigators think that sedentary intervention and stress management may have benefits on these health indicators. As such the investigators will examine whether sedentary intervention or stress management can have positive effect on human health by measuring salivary cortisol, blood lipid profile, fasting blood glucose, blood pressure, resting energy expenditure, and body composition.
Hypotension is a recognized frequent complication of induction of anesthesia. The intent of this research is to determine the incidence of hypotension in patients receiving anesthetic induction with propofol. This investigation seeks to examine how normal clinical practice or a "real world" understanding of the usual response to propofol affects hemodynamics without isolating or standardizing other variables. The current research concerns hypotension in normal clinical practice where variability exists. This project aims to gather information and data in an attempt to form a foundation upon which each of the other variables affecting blood pressure may be subsequently assessed.
To examine the difference in pain control in the pediatric general surgery population alternating acetaminophen and Ibuprofen q 3 hours vs giving them simultaneous combination therapy around the clock.
The purpose of the study is to collect and analyze physiological, physical, and molecular data from a diverse population to increase our understanding of how such parameters are associated with health and disease.
In this between-subject randomized controlled trial the investigators will test the impact of three novel structured financial incentives: atomistic, altruistic and team-based. These incentive schemes will be used to motivate one month of daily use of software designed to improve cognitive function (including memory, reaction times, attention and executive function) among the elderly. The 400 participants will be members of retirement communities in Pennsylvania. Three outcomes will be monitored and analyzed: activities completed using the software (primary), performance on the activities, and changes in cognitive functioning. This study is designed to be a pilot study. The investigators will have 90% power to find a mean daily difference of 4 activities completed in the control group versus 7 activities completed in the incentive groups assuming a standard deviation of 3.5 and an alpha of 0.017 (the bonferroni corrected significance level to account for multiple comparisons). In addition during a three month "follow-up period" all participants will have continued access to the software, however, no incentives will be provided for use. This period will be used to assess the impact of the initial incentives on long run use after financial incentives have ceased.
Surgery performed during general anesthesia induces a stress effect on the body. Our plan is to identify population at risk of hyperglycemia during perioperative period.
