Constipation is a common and debilitating non-motor symptom of Parkinson disease (PD) that often precedes the onset of classic motor symptoms by decades. There is no standardized algorithm for managing constipation in this patient population, nor are there dedicated treatments. Studies suggest that constipation can affect quality of life to a significant degree, in many cases just as much as motor symptoms. There is an unmet need for effective treatment options for constipation in this patient population. The goal of this study is to determine the efficacy and safety of pyridostigmine as a treatment for chronic constipation in patients with PD. Read Less

Thrombosis is common and contributes significantly to morbidity and mortality in patients with cancer. At least 20% of patients with cancer develop venous thromboembolism (VTE) and another 5% will experience acute arterial thromboembolism (ATE) due to cancer and its treatment. Current guidelines recommend VTE thromboprophylaxis in high-risk outpatients. Thromboprophylaxis strategies are inadequate as 50% of high-risk patients on prophylaxis still develop a VTE, the rate of recurrent VTE is ~24% with a case fatality rate of 14.8%, and the incidence of major bleeding is ~13% with a case fatality rate of 8.9%. We and others have implicated platelets in both the pathogenesis of VTE as well as cancer growth and metastasis. To investigate a new biomarker of risk in patients with cancer, we propose a pilot study to determine whether quantification of platelet FcɣRIIa expression can discriminate risk of VTE and cancer progression. We chose platelet FcɣRIIa expression because we have found that quantifying platelet surface expression of FcγRIIa identifies patients at high and low risk of thrombotic arterial events. Thus, we hypothesize that elevated platelet expression of FcγRIIa will identify patients with cancer who are greater risk of VTE as well as cancer progression. The proposed studies leverage a clinical research program that was established in 2015 at the University of Vermont Cancer Center (Venous Thromboembolism Prevention in the Ambulatory Care Clinic [VTEPACC]) and will allow simultaneous access to research samples, thrombosis complications and cancer outcomes in order to achieve the following specific aims: 1) To determine whether platelet expression of FcγRIIa identifies cancer patients at high and low risk of VTE, and 2) To determine whether increased platelet expression of FcγRIIa is associated with a) advanced stage cancer at the time of enrollment and b) greater progression of cancer. Platelet reactivity is increased in patients with cancer and has been associated with VTE risk. Platelet expression of FcγRIIa can increase the risk of thrombosis by both increasing platelet reactivity and by promoting the procoagulant potential of platelets. In addition, platelets promote cancer by facilitating tumor vascularization, growth, and metastasis. FcγRIIa has been shown to be a key mediator of platelet secretion and cross-talk between platelets and tumor cells. Thus, we propose that increased platelet FcγRIIa expression will be linked to enhanced tumor growth and metastasis by facilitating cancer-tumor cell cross-talk and thereby the activation of platelets that leads to the release of platelet products. Identification of a biomarker capable of discriminating high and low risk of VTE will provide an important precision tool that could be combined with existing tools to guide therapy and improve outcomes. Results from aim 2 will provide key preliminary data in support of novel antiplatelet treatments to limit cancer progression. Read Less

Prediction of walking recovery after stroke can inform patient-centered care and support discharge planning. The accuracy of current prediction models is limited, however, due to small study designs and narrow predictors assessed. The investigators propose a comprehensive evaluation of a novel combination of biomarkers to improve prediction of walking recovery and guide rehabilitation efforts after stroke. These include acute structural brain network disruption (utilizing MRI); blood biomarker levels (e.g., brain-derived neurotrophic factor and vascular endothelial growth factor); and clinical assessments of strength and mobility. The overall study objectives are to assess protocol feasibility and investigate relationships between select biomarkers and walking recovery to provide strong justification for a larger study on predictors of independent walking after stroke. The proposed objectives will be pursued through the following specific aims: 1) Assess feasibility of a larger study and develop methods for telehealth data collection; 2) Establish baseline levels of biomarkers and average change over time; and 3) Elucidate relationships between baseline levels of biomarkers and walking gains across time in persons after stroke. A longitudinal, observational study design will be utilized for this study. Thirty-five persons with acute (≤7 days) stroke will be recruited from the local medical center. Select inclusion criteria include presence of new lower limb weakness and assistance for walking; select exclusion criteria include cerebellar stroke or other neurological disorders such as Parkinson's Disease. Subjects will undergo clinical evaluation at week 1, 4, 9, 12, and 26 weeks post-stroke. MRI scans will occur within 12 days post-stroke and at 12 weeks post-stroke, and blood draws within 1 week, 1 to 2 weeks and at 12 weeks post-stroke. To assess feasibility the investigators will examine study processes, recruitment, resources, study management, and scientific assessment. To examine the role of acute clinical, neuroimaging, and physiological measures in predicting walking recovery, the investigators will examine relationships between these measures and walking outcome at 12-weeks post-stroke. The proposed research is expected to provide strong scientific support for future clinical trials designed to target therapies based on predicted functional potential. Such knowledge has the potential of enhancing mobility gains and patient independence following stroke. Read Less

The goal of this study is to test the feasibility of guiding as-needed pharmacological rate control of atrial fibrillation (AF) by implantable cardiac monitors and to assess the impact of continuous beta-blocker therapy versus as-needed rate control on the following outcomes: (1) exercise capacity, (2) AF burden, (3) symptomatic heart failure, (4) biomarker assessment of cardiac filling pressures and cardio-metabolic health, and (5) quality of life in patients with atrial fibrillation and stage II or III heart failure with preserved ejection fraction.

With this pilot investigation, the investigators aim to challenge the reliance on opiate analgesia following colon and rectal surgery. Narcotic misuse and abuse is a pressing public health concern, and reduction in prescription rates could help to mitigate this issue. The goal of this pilot study is to establish feasibility of sufficient post-operative pain control after colectomy using non-narcotic analgesics. The investigators hypothesize that patients will be able to manage their post-operative pain without narcotic intervention, while minimizing side effects and complications. This initial pilot study will provide proof-of-concept for a larger, randomized investigation on non-narcotic analgesia after colectomy. Read Less

The U.S. Committee for Refugees and Immigrants (USCRI) has developed the Relationships, Education, Advancement, and Development for Youth for Life (READY4Life) Program. This is a 16-hour program for immigrants/refugees, ages 14 to 24. The program is designed to help young immigrants and refugees prepare for a successful life in the United States. The program is taught by USCRI program staff and is being implemented at eight sites across the U.S.: Cleveland, Ohio; Colchester, Vermont; Des Moines, Iowa; Miami, Florida; Philadelphia, Pennsylvania; Raleigh, North Carolina; Saint Paul, Minnesota; and Twin Falls, Idaho. The project also includes a rigorous evaluation component, featuring a Randomized Control Trial (RCT) design. Read Less
