Healthy Clinical Trials in Pittsburgh, PA

The iCaRe2 is a multi-institutional resource created and maintained by the Fred \& Pamela Buffett Cancer Center to collect and manage standardized, multi-dimensional, longitudinal data and biospecimens on consented adult cancer patients, high-risk individuals, and normal controls. The distinct characteristic of the iCaRe2 is its geographical coverage, with a significant percentage of small and rural hospitals and cancer centers. The iCaRe2 advances comprehensive studies of risk factors of cancer development and progression and enables the design of novel strategies for prevention, screening, early detection and personalized treatment of cancer. Centers with expertise in cancer epidemiology, genetics, biology, early detection, and patient care can collaborate by using the iCaRe2 as a platform for cohort and population studies. Read Less

The study will evaluate the feasibility of using smartphone speakers and microphones to evaluate the caliber of the airways, detect airway obstruction, aid in airway disease diagnosis, and identify disease exacerbations. Read Less

Neuromodulation is a fast growing field that offers a wide range of applications for both understanding and treating the brain. Future research for non-invasive neuromodulation will need to elucidate the optimal frequency, duration, and intensity of stimulation for a variety of technologies and diseases. Closed loop stimulation is thus a promising research area that allows for responsive stimulation and real time symptom management. Our project is proposed to develop and test a novel noninvasive neuromodulation integrating transcranial focused ultrasound stimulation (tFUS) with electrophysiological source imaging (ESI-tFUS) to allow evidence-based neuromodulation for brain research and the management of brain conditions. Despite the recent developments and attention surrounding tFUS, relatively little is known about the mechanisms and optimal parameters of this stimulation technology. The addition of ESI neuroimaging, aimed at providing biomarkers to assess the effects of tFUS neuromodulation, could provide crucial necessary information regarding the neural response to the applied stimulation in real-time. In order for tFUS to be further developed and transformed into a robust neuromodulation technology, an integrated electrophysiological source-imaging-guided tFUS system to allow for individualized and responsive stimulation is needed. The purpose of this study is to develop and evaluate the proposed ESI-tFUS in human subjects using motor and somatosensory paradigms. Read Less

This is an exploratory study that will determine and standardize how best to record gastric evoked potentials (GEPs) elicited by a non-invasive method of brain stimulation (Transcranial Magnetic Stimulation, TMS), by optimizing the TMS parameters and cortical sites necessary to evoke GEPs.

Moderate to vigorous intensity physical activity is known to reduce the risk of hypertensive disorders of pregnancy and other adverse pregnancy outcomes that increase future maternal cardiovascular disease risk (2018 Physical Activity Guidelines Advisory Committee, 2018; Davenport et al., 2018), yet less than 25% of pregnant women meet public health physical activity guidelines (Hesketh & Evenson, 2016). More than 95% of the 24-hour day is spent in sedentary behavior, sleep, or light-intensity activity; however, the impacts of these lower intensity activities on adverse pregnancy outcomes are unknown. This multi-site observational cohort study (N=500) will leverage state-of-the-art, 24-hour behavior assessment in each trimester of pregnancy and examine associations with adverse pregnancy outcomes to inform guidelines and future interventions designed to improve women's pregnancy and long-term cardiovascular health.
