3 Clinical Trials for Various Conditions
Infants often present to the hospital with episodes of coughing, choking, gagging, change in muscle tone, and/or change in skin color, known as brief resolved unexplained event. Many studies have tried to address why infants have these symptoms and if there is a way to prevent them from happening again. Currently, there is no clear agreement on the most common cause of these symptoms or how to prevent them. Some studies have suggested that gastroesophageal reflux can cause these symptoms. The investigators are conducting a study of infants who are admitted to Boston Children's Hospital with episodes of coughing, choking, gagging, change in muscle tone, and/or change in skin color, symptoms that could be reflux. The investigators want to determine if these symptoms can be prevented by changing the way infants are fed, either by giving them a formula to treat reflux or by thickening their feeds to treat reflux. The goal of the study is to determine if different types of feeding interventions prevent infants from coming back to the hospital.
This observational, non-interventional survey study is intended to explore user experiences with the LifeVac airway clearance device, with a particular emphasis on real-world application in choking emergencies in the USA. This study seeks to gather valuable insights from a representative sample of the LifeVac device purchaser base. The main questions the study aims to answer are: 1. Is the LifeVac device safe for individuals experiencing a choking emergency? 2. Is the LifeVac device successful in removing an obstruction during a choking incident? Participants: Purchasers of the LifeVac device.
The purpose of this study is to examine the acute effect of being choked during partnered sex on neurological measures. The study is designed to identify the effects being choked during partnered sex on the brain through the use of neural-injury blood biomarkers, functional, diffusion, and perfusion MRI, and ocular-motor function across 3 time points (baseline, post-choking, post-non-choking). The central hypothesis is that acute neuronal structural, physiological, and functional alterations will be amplified after an incidence of choking-involved sex. The neural-injury blood biomarkers neurofilament light (NfL), glial fibrillary acidic protein (GFAP), Ubiquitin C-Terminal Hydrolase L1 (UCH-L1), and Tau will be measured in plasma, with the hypothesis that having choking involved sex will result in a increased heightened response compared to baseline and post non-choking involved sex timepoints. An additional panel of inflammatory cytokines may be considered if/when brain injury biomarkers show changes. It is also hypothesized that engaging in choking-involved sex will be associated with changes in fMRI activation patterns. White matter microstructure will be measured by diffusion imaging metrics, with the hypothesis that engaging in choking-involved sex will significantly disrupt microstructure at a post-choking involved sex time point, compared to baseline, but not at the post non-choking involved sex timepoint. The study will also assess oculomotor function as measured by near-point-of-convergence (NPC) in response to engaging in choking involved sex. The hypothesis is that NPC performance will be significantly impaired at the post choking-involved sex timepoint in comparison to both baseline and non-choking involved sex timepoints.
