The goal of this study is to This research team is conducting this study to develop methods to measure the biological impact of exposure to the chemicals released following the February 3, 2023 train derailment on residents of East Palestine, Ohio, and surrounding communities. The main question it aims to answer is: * What biological impact will be measured based on DNA damage? * In participants who provide a biospecimen, how are biomarker changes related to proximity to the derailment and variations in residents' health histories and behaviors? Participants will: * Complete a brief survey asking about experiences related to the February 3, 2023 train derailment, health experiences, and concerns following the derailment, and background information regarding health history. * Possibly contribute biospecimens such as blood, spit, hair, and/or toenail clippings. * Receive communication about study updates and future research opportunities. * A total of 40 study participants will be recruited to participate in a 90-minute interview. The interviews will be video and audio recorded. Read Less

This study will utilize the Moxy wearable sensor to measure muscle oxygen saturation levels in athletes following lower extremity surgery (ACL or Hip arthroscopy) to evaluate their Return-to-Play. The acquired data will complement current protocols utilized by Dr. Voos and Dr. Salata in this regard and will add quantifiable evidence to enable a robust measurement of the surgical limb versus non-surgical limb.

The hypothesis is that SEV result in superior valvular hemodynamics (more pronounced during exercise) and exercise capacity relative to BEV. Furthermore, the hypothesis is that stress CMR will be able to demonstrate differences in these hemodynamic parameters. CMR will also provide refined assessment of paravalvular leak and its impact on ventricular function and on clinical outcomes. Read Less

Our group has recently identified the association between gut-flora-mediated carnitine and phosphatidylcholine metabolism, specifically trimethylamine-N-oxide (TMAO), and cardiovascular risk. This study investigates the ability for dietary intervention to modulate TMAO levels. Read Less

The purpose of the Cardiovascular and Metabolic Sciences Biorepository is to collect and store information and biospecimens (blood, urine, stool, and heart tissue) from patients with and without cardiovascular and metabolic diseases to create a readily available biorepository of samples and related medical health information to expedite future research into the causes and consequences of cardiovascular and metabolic diseases.

The purpose of this study is to evaluate a surgically implanted functional electrical stimulation (FES) system to facilitate stability of the trunk and hips. FES involves applying small electric currents to the nerves, which cause the muscles to contract. This study evaluates how stabilizing and stiffening the trunk with FES can change the way spinal cord injured volunteers sit, breathe, reach, push a wheelchair, or roll in bed. Read Less

Traditional rehabilitation approaches are time and personnel intensive and costly, and leave \~75% of stroke survivors with residual disability. We propose a clinical trial to determine effects of forced aerobic exercise (FE; i.e., mechanically supplemented) in facilitating upper and lower extremity motor recovery post-stroke in an outpatient rehabilitation setting, to elucidate neural and biochemical substrates of FE-induced motor recovery, and to evaluate cost effectiveness of a FE-centered intervention compared to traditional stroke rehabilitation. The global effect of FE has the potential to enhance recovery in a growing population of stroke survivors in a cost-effective manner, thus accelerating its clinical acceptance. Read Less

The Purpose of the study is to test the hypothesis that administration of an S-nitrosylating (SNO) agent can improve tissue oxygenation during transfusion of packed red blood cells (RBCs). Read Less

Abnormalities of the lungs are common in newborns and can include aspiration or infectious pneumonia, respiratory distress syndrome (RDS), bronchopulmonary dysplasia (BPD), pulmonary hypertension (PH), congenital diaphragmatic hernia (CDH), and other abnormalities of lung development. Diagnostic radiography is commonly used in this population to differentiate diagnosis and to assess changes after treatment. While X-ray and CT provide quality imaging, they also expose infants to ionizing radiation. MR imaging offers a safe, non-ionizing alternative. However, imaging lungs via 1H MR is intrinsically difficult due to multiple air-tissue interfaces within the lungs causing local gradients and severe magnetic field susceptibility, which leads to an exceedingly short effective transverse relaxation time (T2\*). Additionally, the lungs have low proton density, which along with the short T2\* results in low signal to noise ratio, and the physiological motion caused by respiration and cardiac pulsation further reduces lung signal. The development of more powerful hardware, along with faster MRI techniques, has enabled detailed noninvasive 1H MR imaging of pulmonary tissues. Additionally, the development of inhaled hyperpolarized gas MRI has led to breakthroughs in the ability to visualize and quantify regional ventilation and alveolar size. Read Less

To create a validated computational tool to predict surgical outcomes for pediatric patients with obstructive sleep apnea (OSA). The first line of treatment for children with OSA is to remove their tonsils and adenoids; however, these surgeries do not always cure the patient. Another treatment, continuous positive airway pressure (CPAP) is only tolerated by 50% of children. Therefore, many children undergo surgical interventions aimed at soft tissue structures surrounding the airway, such as tonsils, tongue, and soft palate, and/or the bony structures of the face. However, the success rates of these surgeries is surprisingly low. Therefore, there a need for a tool to improve the efficacy and predict which surgical option is going to benefit each individual patient most effectively. Computational fluid dynamics (CFD) simulations of respiratory airflow in the upper airways can provide this predictive tool, allowing the effects of various surgical options to be compared virtually and the option most likely to improve the patient's condition to be chosen. Previous CFD simulations have been unable to provide information about OSA as they were based on rigid geometries, or did not include neuromuscular motion, a key component in OSA. This project uses real-time magnetic resonance imaging (MRI) to provide the anatomy and motion of the airway to the CFD simulation, meaning that the exact in vivo motion is modeled for the first time. Furthermore, since the modeling is based on MRI, a modality which does not use ionizing radiation, it is suitable for longitudinal assessment of patients before and after surgical procedures. In vivo validation of these models will be achieved for the first time through comparison of CFD-based airflow velocity fields with those generated by phase-contrast MRI of inhaled hyperpolarized 129Xe gas. This research is based on data obtained from sleep MRIs achieved with the subject under sedation. While sedating the patient post-operatively is slightly more than minimal risk, the potential benefits to each patient outweigh this risk. As 58% of patients have persistent OSA postsurgery and the average trajectory of OSA severity is an increase over time, post-operative imaging and modeling can benefit the patient by identifying the changes to the airway made during surgery and which anatomy should be targeted in future treatments.

The study team proposes that use of a novel multi-disciplinary approach with continuous glucose monitoring technology can significantly improve glycemic control and reduce readmissions among those with type 1 diabetes mellitus (T1DM) admitted for Diabetic ketoacidosis (DKA). This will also help promote a pathway for care of these patients after admission utilizing resources which are available within the Endocrinology, Diabetes and Metabolism department at the Cleveland Clinic.
