Raleigh, NC Paid Clinical Trials

Pessaries are effective non-surgical devices for reduction of prolapse. However, use of pessaries are limited in some women due to patient discomfort. While lidocaine can be used to improve pessary checks, its use may be limited due to supply chain shortages, lack of insurance coverage, and optimization of resource utilization. More techniques to improve pessary examination comfort are needed. Perineal massage prior to delivery and at the time of active labor has been noted to reduce perineal trauma and perineal discomfort, theoretically by desensitizing the nerve endings in the skin, broadening the vaginal opening, and increasing elasticity of the perineal tissue. Since most discomfort with pessary checks is during removal and insertion through the vaginal introitus, perineal massage may be a beneficial technique that women could potentially learn to improve comfort with pessary checks. The objective of this study is to examine the effectiveness of perineal massage prior to pessary check in improving comfort of pessary checks for patients using a cross-over randomized controlled trial. Patients who follow up for pessary checks with the division of Urogynecology at UNC will be approached about participating in this study. The study will involve two clinical visits. At the first visit, the patient will be randomized to 2 minutes of perineal massage with water based gel of the external perineum and sides of the vaginal vestibule, as well as internal massage with the thumb, gliding from 4 to 8 o'clock, then tissue stretching technique with one intracavitary finger and other external finger at the 4 o'clock and 8 o'clock positions three times; versus application of gel to the internal vagina and external vagina without massage. Providers will be blinded to randomization and proceed with pessary check as per normal clinical protocols. Patients will rate self-reported pain before, during pessary check, and after the pessary check on a VAS scale; and rate whether they would prefer to repeat this method at future visits via Likert scale. Healthcare professionals will also rate perceived patient pain on VAS scale; ease of pessary removal; and note any perineal or introital laceration or abrasion that may occur during the pessary fitting. At the following visit, patients will be assigned to the group to which they were not initially randomized. Patients and healthcare professionals will again rate pain as described above. Patients will also rank preference for perineal massage using PGI-I. Read Less

The goal of this clinical trial is to learn about the role of flavored on!® nicotine pouch products (the research products), an oral tobacco-leaf-free product, in the replacement of cigarettes with the use of the research products among adults who smoke cigarettes. The main question it aims to answer is whether flavored (vs. non-flavored) research products generate greater reduction of cigarette smoking among adults who smoke cigarettes. Participants will be provided with research products to use for 6 weeks. Researchers will compare the reduction in cigarette smoking between participants with access to a complete flavor profile of research products and participants with access to only the Original (non-flavored) variety of research product to see if reduction in cigarette smoking is greater among those with access to flavored research products.

This randomized phase III trial studies how well crizotinib works in treating patients with stage IB-IIIA non-small cell lung cancer that has been removed by surgery and has a mutation in a protein called anaplastic lymphoma kinase (ALK). Mutations, or changes, in ALK can make it very active and important for tumor cell growth and progression. Crizotinib may stop the growth of tumor cells by blocking the ALK protein from working. Crizotinib may be an effective treatment for patients with non-small cell lung cancer and an ALK fusion mutation. Read Less

The objective of this proposal is to investigate the effects of training to use direct electromyographic (dEMG) control of a powered prosthetic ankle on transtibial amputees'. The aimed questions to answer: 1. whether dEMG control will improve balance and postural stability of amputees, 2. whether dEMG control will lead to more natural neuromuscular control and coordination, 3) whether dEMG control will reduce cognitive processes. Participants will go through PT guided training on using dEMG controlled prosthetic ankles and are evaluated for their capability on functional tasks. The results will be compared with a comparison group, which goes through the same training but with their everyday passive prostheses on balance capability, neuromuscular coordination, and cognitive load during locomotion.

The purpose of the HF2 (Hemodynamic Frontiers in Heart Failure) registry is to collect relevant patient-level demographic, clinical, laboratory, and hemodynamic data from patients implanted with pulmonary artery pressure sensor at participating centers to advance scientific knowledge about ambulatory hemodynamics monitoring and HF (Heart Failure) therapies. The data collected will be used for retrospective studies, quality improvement, identifying research cohorts, and member-initiated research. Read Less

Intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) has been shown in clinical trials, registries, and meta-analyses to reduce recurrent events after PCI. This is accomplished by improving the angiographic result with lesion and vessel assessment to guide stent selection and implantation and intravascular imaging following stent implantation to ensure an adequate treatment endpoint has been achieved. Despite extensive literature supporting the use of IVUS in PCI, utilization remains low in the United States. An increasing number of high-risk or complex lesions are being treated with PCI and we hypothesize that the impact of IVUS in these complex lesions will be of increased importance in reducing clinical adverse events while remaining cost effective.

To identify asthma-related physiological changes observed by wearable devices in real-world conditions by monitor multiple sensing modalities (e.g., heart rate (HR), heart rate variability (HRV), activity level, spirometry, coughing sounds) in order to find reliable signatures of impending asthma exacerbation and systematically explore any challenges on the use of wearable technologies.

Robotic lower limb exoskeletons aim to improve or augment limb functions. Automatic modulation of robotic assistance is very important because it can increase the assistive outcomes and guarantee safety when using exoskeletons. However, this automatic assistance adjustment is challenging due to person-to-person and day-to-day variations, as well as the time-varying complex human-machine-interaction forces. In recent years, human-in-the-loop optimization methods have been investigated to reduce participants' metabolic costs by providing personalized assistance from robotic exoskeletons. However, metabolic cost measure is noisy and the experimental protocol is usually relatively long. In addition, the influence of exoskeleton control on this human state in terms of energetic cost is unclear and indirect. More importantly, the optimization by reducing metabolic cost is found to affect human gait patterns and cause undesired outcomes. In this study, new evaluation measures other than metabolic cost will be investigated to optimize the assistance from a powered hip exoskeleton based on a reinforcement learning method. It is hypothesized that the new reinforcement learning-based optimal control approach will produce personalized torque assistance, reduce human volitional effort, and improve balance and other performance during walking tasks. Both participants without and with neurological disorders will be included in this study. Read Less

Lower limb amputees rely on their prosthetic to remain active and lead an independent life. In recent years, measuring residual muscle activity has been used to interpret a user's intent and thereby modulate prosthesis control. However, little knowledge is held on how residual muscle activity differs from non-amputated muscle. The research team will analyze and compare neuromuscular physiology in non-amputee individuals and amputees' non-amputated and residual muscles across functional tasks to better understand how amputees control their muscles. Such information will inform design of modern prosthesis controllers. Read Less
