The purpose of this study is to evaluate the effects of pyridostigmine (Mestinon) on patient vocal outcomes after undergoing laryngeal botulinum neurotoxin (BoNT) injections, which is a standard treatment for spasmodic dysphonia. Pyridostigmine (Mestinon) has been used for treatment of BoNT overdose, and it is our hope that it will be beneficial in the management of post BoNT breathy phase. Read Less

This study is designed to evaluate the safety and efficacy of dipraglurant in PD patients with dyskinesia (randomized 1:1 to receive active or placebo) for 12 weeks (1 week at 150 mg per day and 11 weeks at 300 mg per day). The primary efficacy assessment will be based on the Unified Dyskinesia Rating Scale (UDysRS). Patients who complete the 12-week blinded treatment period may have the option to roll into an open-label safety extension study for an additional 12-month treatment period. Read Less

The objective of our study is to evaluate the effect of CPAP on umbilical cord acid base status in morbidly obese women at the time of scheduled cesarean delivery. We hypothesize that neonates born to mothers wearing CPAP during the cesarean section will have a higher umbilical artery pH. Read Less

The pharmacodynamic endpoint of percentage of subjects with suppressed estradiol level (less than 20 pg/mL) on cycle day 29 is the primary endpoint of the study. Read Less

The purpose of this study is to study the potential benefit of treating chronic neurogenic cough by blocking the nerve responsible for the disease with an injection of local anesthetic/steroid mixture versus a placebo. Read Less

This is a single arm study of home monitoring with the NVHO for 5 weeks with office visits at enrollment, Week 1 and Week 5 (Exit Visit) and, when applicable, Interim Visit(s) triggered by ongoing review by the Reading Center. The study will enroll subjects diagnosed with NV-AMD in at least one eye with attention to the proportion of eyes with IRF and/or SRF. The enrolled eligible subjects will be instructed to self-image the study eye(s) once daily for 5 weeks using a NVHO device at home with scheduled in-office examinations at Week 1, Week 5 and Interim Visits, when applicable, with additional in-office Cirrus volume scans acquired at these office visits. The self-imaging data on the NVHO will be automatically uploaded to the Notal Health Cloud and from there the reconstructed volume scans will sent to the study database. Read Less

In 2017, the American College of Cardiology and the American Heart Association changed the diagnostic criteria for hypertension in non-pregnant adults. The parameters for the diagnosis of stage 1 hypertension were revised from a systolic blood pressure (BP) of 140 to 130 mm Hg and a diastolic BP of 90 to 80 mm Hg. Based on new criteria, stage 1 hypertension is associated with a 2-3 fold increased risk of preeclampsia. There are no data regarding prevention of preeclampsia in women with stage 1 hypertension. Low-dose aspirin has been used during pregnancy to prevent preeclampsia for women at high-risk for preeclampsia. Although the precise mechanism remains uncertain, it is possible that low-dose aspirin improves placental perfusion, which results in a decreased rate of preeclampsia. A study that examines the effect of low-dose aspirin on placenta vasculature and tissue elastography by using novel ultrasound tools would be useful. The 2017 Aspirin for Evidence-Based Preeclampsia Prevention trial compared 150 mg aspirin with placebo in women at high-risk of preeclampsia based on a first-trimester screening. They found a significant decrease in the rate of preterm preeclampsia (4.3% vs. 1.6%; P <0.01). Since this study used the screening algorithm including first-trimester serum markers and uterine artery Doppler, the generalizability in the U.S. women with stage 1 hypertension is limited. Our pilot study will examine 1) the effect of low-dose aspirin 81 mg in women with stage 1 hypertension on placental vasculature and shear-wave elastography; 2) the rate of preterm preeclampsia in women with stage 1 hypertension in a control group and in pregnancies treated with low-dose aspirin 81 mg; 3) feasibility of conducting a larger multicenter randomized controlled trial on this subject.

This study is looking to minimize side effects, while maintaining and potentially improving the therapeutic benefit to patients suffering from Female Sexual Arousal Disorder by providing a topical preparation of Sildenafil locally to the vulvar-vaginal tissue. Read Less

The investigators are conducting a study to compare the self-reports of executive functions (that is to say, what role cognitive processes such as working memory and attention) in persons with Parkinson's Disease to the reports of executive functions completed by their significant others. To conduct this study, the investigators need the participation of persons who are diagnosed with Parkinson's Disease and their significant others. Read Less

This study will examine the impact of cardiac rehabilitation on blood vessel health using a newly developed microfluidic-based tactile sensor to assess blood vessel health. The participants will have their blood vessel health measured using a sensor that is placed on top of the skin over the artery before and after exercise (1, 3, 5, 10, 30 and 60 mins). The investigators will study these responses at the first session of cardiac rehabilitation and following 1 and 4 weeks of cardiac rehabilitation (sessions 3 and 6). The investigators will also collect some information from the medical record regarding: age, gender, body mass index, resting cardiovascular measures (heart rate, blood pressure etc), medications, reasons which qualified the participant into cardiac rehabilitation, blood tests related to heart or cardiovascular function, metabolic panel, lipid panel, echocardiogram results, recorded electrocardiogram, known vascular diseases, presence of implantable devices, Seattle Heart Failure Model data and cardiovascular measures and exercise workloads during cardiac rehabilitation.
