People released from prison experience two times higher cardiovascular (CV) mortality than the general population, have a high prevalence of poor CV health and increased risk of CV events within 2 years of release. Access to high quality healthcare following release from prison is key to preventing poor health and CV outcomes. Our study team will investigate facilitators and barriers to health care access experienced by people released from prison. Read Less

The purpose of this study is to learn the best approach to treating patients with known or suspected Barrett's esophagus by comparing endoscopic surveillance to endoscopic eradication therapy. To diagnose and manage Barrett's esophagus and low-grade dysplasia, doctors commonly use procedures called endoscopic surveillance and endoscopic eradication therapy. Endoscopic surveillance is a type of procedure where a physician will run a tube with a light and a camera on the end of it down the patients throat and remove a small piece of tissue. The piece of tissue, called a biopsy, is about the size of the tip of a ball-point pen and is checked for abnormal cells and cancer cells. Endoscopic eradication therapy is a kind of surgery which is performed to destroy the precancerous cells at the bottom of the esophagus, so that healthy cells can grow in their place. It involves procedures to either remove precancerous tissue or burn it. These procedures can have side effects, so it is not certain whether risking those side effects is worth the benefit people get from the treatments. While both of these procedures are widely accepted approaches to managing the condition, there is not enough research to show if one is better than the other. Barrett's esophagus and low-grade dysplasia does not always worsen to high-grade dysplasia and/or cancer. In fact, it usually does not. So, if a patient's dysplasia is not worsening, doctors would rather not put patients at risk unnecessarily. On the other hand, endoscopic eradication therapy could possibly prevent the worsening of low-grade dysplasia into high-grade dysplasia or cancer (esophageal adenocarcinoma) in some patients. Researchers believe that the results of this study will help doctors choose the safest and most effective procedure for their patients with Barrett's esophagus and low-grade dysplasia. This is a multicenter study involving several academic, community and private hospitals around the United States. Up to 530 participants will be randomized. This study will also include a prospective observational cohort study of up to 150 Barrett's esophagus and low grade dysplasia patients who decline randomization in the randomized control trial but undergo endoscopic surveillance (Cohort 1) or endoscopic eradication therapy (Cohort 2), and are willing to provide longitudinal observational data.

The objective of this study is to collect and evaluate long-term clinical and radiographic outcomes data in order to better understand the safety and performance of the shoulder arthroplasty over time. This study will follow subjects long-term for a minimum of 10-years, without an early-term restriction on the amount of time they will be followed. Read Less

High blood pressure (BP) is the major modifiable risk factor for cardiovascular diseases (CVD) and related health conditions, particularly among postmenopausal (PM) women. In adults age ≥50 years this risk is primarily driven by above-normal systolic BP (SBP ≥120 mmHg), as diastolic BP plateaus, then decreases in older adulthood. Although SBP is lower in premenopausal women vs. age-matched men, SBP reaches, then surpasses men after age 60. As such, \>75% of PM women in the U.S. have above-normal SBP, which, in turn, is responsible for a 2-fold increase in risk of hypertension and corresponding increases in risk of CVD, chronic kidney disease and many other disorders. A key process linking high SBP to CVD and related conditions is vascular endothelial dysfunction, mediated by excessive reactive oxygen species (ROS)-induced oxidative stress and reductions in nitric oxide (NO) bioavailability. As the number of PM women is rapidly growing, further increases in SBP-related CV disorders are projected without effective intervention. * Aerobic exercise (AE) is a first-line, standard-of-care therapy for lowering BP. In PM women with baseline SBP ≥120 mmHg, AE reduces casual (resting) SBP by \~3 mmHg (back to baseline ≤4 weeks post-training), whereas 24-hour SBP is typically unchanged. However, only 25-30% of PM women meet guidelines for 150 min/week of moderate-intensity AE, citing the extensive time requirement, facility access and travel disruptions as major barriers. Another, far less recognized, limitation is that AE training consistently improves endothelial function in midlife/older men, but not in estrogen-deficient PM (PMe-) women, i.e., in \>95% of the 60+million PM women in the U.S. Thus, establishing new lifestyle therapies that induce and sustain reductions in SBP and increases in endothelial function in PMe- women with above-normal SBP is an important public health goal. * High-resistance inspiratory muscle strength training (IMST) is a time-efficient (5 minutes per session) lifestyle intervention consisting of 30 inspiratory maneuvers performed against a high resistance. Preliminary data suggest 6-weeks of IMST performed 6 days/week reduces SBP by 9 mmHg in adults with above-normal SBP (i.e., greater than 120 mmHg) at baseline. Importantly, this reduction in SBP is equal to or greater than the reduction in blood pressure typically achieved with time- and effort-intensive healthy lifestyle strategies like conventional aerobic exercise. In addition, IMST improved endothelial function in the PMe- women in a small pilot study. * To translate these promising preliminary results towards clinical practice, this randomized clinical trial is being conducted to directly compare the efficacy of a longer, clinically relevant treatment duration of IMST (3 months) against home-based, moderate-intensity (standard-of-care) AE in PMe-women. The primary outcome will be the change in casual SBP (IMST vs. AE). Changes in 24-hour SBP and endothelial function will serve as secondary outcomes. Effects on NO bioavailability, ROS/oxidative stress, and the role of "circulating factors" will provide insight into mechanisms of action. The sustained effects on SBP and endothelial function also will be assessed. * Accordingly, a randomized, blinded, sham-controlled, parallel group design clinical trial will be conducted to assess the efficacy of 3-months of IMST (75 percent maximal inspiratory pressure) vs. brisk walking (40-60% heart rate reserve; an established healthy lifestyle strategy) for lowering SBP and improving endothelial function in PMe- women age 50 years and older with above-normal SBP. It is hypothesized that IMST will lower SBP and improve endothelial function by decreasing oxidative stress and increasing nitric oxide bioavailability. It is also expect that adherence to the intervention will be excellent (over 80 percent of all training sessions completed at the appropriate intensity). * To test this hypothesis, 90 PMe- women age 50 years and older who have SBP \>/= 120 mmHg will be recruited. Participants will undergo baseline testing for casual (resting) SBP, 24-hour ambulatory SBP and endothelial function. Innovative mechanistic probes including pharmaco-dissection with vitamin C, analysis of biopsied endothelial cells, and high-throughput metabolomics, will be performed to assess oxidative stress and nitric oxide bioavailability at baseline. * After baseline testing, subjects will be randomized to perform either 3-months of high-resistance IMST or brisk walking. Subjects will train 6 days/week. Following 3 months of training, subjects will redo all the tests that were done during baseline testing to assess training-induced changes in SBP, physiological functions, and underlying mechanisms. Subjects will then cease training for 6 weeks before returning to the lab for follow-up testing to determine the persistent effects of IMST. Read Less
