Autonomic Reactivity and Personalized Neurostimulation
Disorders of gut-brain interaction (DGBI) affect up to 25% of U.S. children. Patients often suffer from disabling, multisystem comorbidities that suggest a common root (sleep disturbances, fatigue, anxiety, etc). Yet, DGBI are defined and treated based on GI symptom origin (cyclic vomiting, dyspepsia, irritable bowel) rather than underlying pathophysiology. Many …
Auricular Vagal Nerve Stimulation for Hypermobile Ehlers-Danlos Syndrome
Hypermobile Ehlers-Danlos Syndrome (hEDS) is a connective tissue disorder characterized by hyperextensible skin, joint hypermobility and additional connective tissue manifestations. For unclear reasons, hEDS is associated with many gastrointestinal (GI) and autonomic nervous system (ANS) complaints such as postural orthostatic tachycardia syndrome (POTS). This study will address the clinical relationship …
A Cohort Study on the Association Between the ANS Function and Acute GvHD
This is a prospective observational study. The investigators plan to utilize this model as a tool for early classification and interrogate ANS function of transplant recipients.
Role of Parasympathetic Activity in Mild to Severe Asthma With Fixed Airway Obstruction (PARASMA Study)
In asthma, the significant role of pathogenesis is chronic airway inflammation, bronchial hyperresponsiveness, and variable airflow obstruction. Asthma with irreversible or fixed airflow obstruction (FAO) is a clinical phenotype resulting from chronic airway inflammation with having longer disease duration, suggesting that airway remodeling contributes to the decline in lung function …
Autonomic Dysfunction in Functional Dysphonia
The first objective of this research project is to compare the occurrence and frequency of symptoms and/or disorders related to autonomic dysfunction in patients with functional dysphonia with gender- and age-matched vocally healthy controls, using a case-control study. The second objective is to compare the effects of a novel therapy …
Vagus Nerve Stimulator for Autism and Other Developmental Disorders
The goal of this flexible single-subject design vagus nerve stimulation (VNS) study is to examine the behavioral, cognitive, and biorhythmic effects of VNS in children and adults with autism and developmental disabilities. The main aims are: Pilot the creation of a profile for those who will respond to VNS with …
Autonomic Effects of Stimulation in SCI
This study aims to determine the effects of transcutaneous spinal cord stimulation to increase blood pressure and use that device to increase exercise endurance time and heart rate recovery during arm cycle ergometry. In addition, the investigators will see if the stimulation helps regulate body temperature when in a cool …
Intraoperative Autonomic Blockade for Laparoscopic Cholecystectomy
This study proposes infiltrating the hepatoduodenal ligament and the serosal reflection of the gallbladder cystic plate with a combination of Bupivacaine (a long-acting local anesthetic) and Dexamethasone (a corticosteroid). This technique aims to block the hepatic branches of the celiac plexus to improve visceral pain control and its associated clinical …
Occipital Nerve Stimulation in Trigeminal Autonomic Cephalgias
The objective of this study is to determine the efficacy of occipital nerve stimulation (ONS) in the treatment of chronic trigeminal autonomic cephalalgias (TACs).
Autonomic Control of the Circulation and VDR
The study objective of this project is to examine the mechanisms of the venous distension reflex (VDR) in humans. We hypothesize that COX blockade with ketorolac tromethamine, an intravenous NSAID, will attenuate the muscle sympathetic nerve activity (MSNA) response to limb venous distension. To gain further insight into whether the …
