The goal of this clinical trial is to compare the number of catheter-free days (CFD) and the rate and severity of any dialysis access-related infections between the ATEV and AVF groups over 12 months in patients with end-stage renal disease (ESRD) needing hemodialysis (HD). Participants will be stratified by location of the vascular access (forearm versus upper arm) and by type of AVF creation procedure planned by the surgeon at randomization (1-stage AVF versus 2-stage AVF). The comparator is an upper extremity arterio-venous fistula (AVF) for HD access surgically created per the institution's Standard of Care (SoC).

Efficacy and Safety of Endoscopic Antral Myotomy as a Novel Weight Loss Procedure
Christopher C. Thompson, MD, MSc Obesity Obesity, Morbid Obesity, Primary Metabolic Disease Delayed Gastric Emptying Following Procedure

Gastric myotomy has been performed for several years as a means of addressing chronic stenosis after sleeve gastrectomy and treating gastroparesis. The Pylorus Sparing Antral Myotomy (PSAM) technique has the opposite effect by leaving the pylorus intact and extending the myotomy proximally to the distal gastric body. PSAM was initially combined with ESG and shown to delay gastric emptying and provide greater weight loss without impacting tolerability (GCSI score) or the safety profile of the procedure (2 DDW GEM abstracts). PSAM has not been evaluated alone, without concomitant ESG. Since delayed gastric emptying alone is known to promote weight loss, it is thought that PSAM alone (without ESG) may provide similar efficacy, while reducing procedure time and adverse events. There have been no clinical studies that investigate the efficacy of PSAM independent of ESG. This pilot study aims to address this lack of information by evaluating the safety, tolerability, and short-term efficacy of PSAM, in addition to exploring its impact on gastric physiology. This will also provide data that may be used in designing a larger clinical trial.

The study will extend recent discoveries that have been made in basic human physiology related to responses melatonin and uterine contractions in late- or full-term pregnant women. The basic physiology work has been conducted in in vitro models of the human myometrium characterizing its responses to melatonin, and in pilot in vivo studies correlating the number of uterine contractions with melatonin concentrations that were manipulated by different types of light exposure. The planned experiments will test a causal link between circulating melatonin levels and uterine contractions in full-term pregnant women by manipulating melatonin levels using exogenous melatonin (i) during the day when endogenous levels of melatonin are very low (Experiment 1), and (ii) during the evening under conditions with lighting that would be expected to suppress the higher evening and nighttime levels of endogenous melatonin (Experiment 2).

The specific aim of this proposed study is to investigate the feasibility and therapeutic potential of transcranial focused ultrasound (tFUS) as a treatment for bipolar disorder (BD). Specifically, the investigators will study the effects of amygdala tFUS on corticolimbic activation during an emotion regulation task in BD, the effects of amygdala tFUS on corticolimbic resting-state functional connectivity in BD, and explore the relationship between tFUS-associated changes in amygdala activity and mood symptoms. The investigators hypothesize that transcranial focused ultrasound (tFUS) of the amygdala will be associated with decreased amygdala activation and increased ventromedial prefrontal cortex activation during a modified version of the Multi-Source Interference Task (MSIT) paired with affective pictures from the International Affective Picture System (IAPS). The investigators also hypothesize that tFUS of the amygdala will be associated with increased resting-state functional connectivity between the amygdala and ventromedial prefrontal cortex. Finally, the investigators hypothesize that tFUS-associated reductions in amygdala activity could be positively correlated with reductions in depressive symptom scores and global improvement.

The Epilepsy Learning Health System (ELHS) is a quality improvement and research network to improve outcomes for people with epilepsy. The ELHS is designed as a model of value-based chronic care for epilepsy as envisioned by the National Academies of Medicine Committee in their landmark reports "The Learning Health System" and "Epilepsy Across the Spectrum: Promoting Health and Understanding". The ELHS network is a collaboration among clinicians, patients and researchers that promotes the use of data for multiple purposes including one-on-one clinical care, population management, quality improvement and research. The ELHS Registry includes data on children and adults with epilepsy collected during the process of standard epilepsy care. These data are used to create population health reports and to track changes in outcomes over time. ELHS teams use quality improvement methods, such as Plan-Do-Study-Act (PDSA) cycles, to continuously learn how to improve care.

Persistent obstructive sleep apnea (OSA) is common in people treated with mandibular advancement device (MAD) or hypoglossal nerve stimulation (HGNS). For most patients, these treatments are the last line of defense. If MAD or HGNS do not work, then patients are left to suffer the consequences of undertreated OSA. In this study, the investigators want to test the addition of a drug treatment to their regimen. Endotypes will be targeted pharmacologically with one of the following drugs: acetazolamide for a high loop gain, atomoxetine-plus-eszopiclone for poor pharyngeal muscle compensation, or trazodone for a low arousal threshold. This aim is expected to provide treatment strategies for rescuing non-responders to MAD or HGNS therapy.

Acute kidney injury (AKI) and chronic kidney disease (CKD) impose a significant global health burden. Yet, no effective therapies currently exist for AKI, and only a few are available for CKD. Despite significant effort from industry and academia, development of pharmacologic therapies for AKI and CKD has been hampered by: Non-predictive animal models The inability to identify and prioritize human targets The limited availability of human kidney biopsy tissue A poor understanding of AKI and CKD heterogeneity Historically, AKI and CKD have been described as single, uniform diseases. However, growing consensus suggests that different disease pathways lead to different subgroups of AKI and CKD (AKIs and CKDs). Access to human kidney biopsy tissue is a critical first step to define disease heterogeneity and determine the precise molecular pathways that will facilitate identification of specific drug targets and ultimately enable individualized care for people with AKI and CKD. A number of research centers across the United States are collaborating to bring state-of-the-art technologies together to: - Ethically obtain and evaluate kidney biopsies from participants with AKI or CKD - Define disease subgroups - Create a kidney tissue atlas - Identify critical cells, pathways, and targets for novel therapies The KPMP is made up of three distinct, but highly interactive, activity groups: - Recruitment Sites: The recruitment sites (RS) are responsible for recruiting participants with AKI or CKD into the longitudinal study and performing the kidney biopsy. - Tissue Interrogation Sites: The tissue interrogation sites (TIS) are responsible for developing and using innovative technologies to analyze the biopsy tissue. - Central Hub: The central hub is responsible for aggregating, analyzing, and visualizing the generated data and providing scientific, infrastructure, and administrative support for the KPMP consortium.
