Vagal nerve stimulation is a neurosurgical procedure consisting of implantation of an impulse generator battery with leads placed into the vagus nerve in the neck. This procedure was FDA approved for epilepsy in the 1990s and is commonly performed as an outpatient surgery. The mechanism of efficacy is not well understood; however it is increasingly recognized that electrical stimulation of the vagus nerve may impact other organ systems in the body including the immune, gastroin...
Spinal cord stimulation (SCS) has been shown to be effective for relieving intractable chronic pain. However, a portion of patients who initially succeed with SCS will eventually lose their therapeutic benefit. Reliable methods have not been identified for restoring neuromodulation benefit to this underserved population, so additional research is required. This study will prospectively observe subjects who utilize Abbott neurostimulation devices after failing to sustain pain re...
Recent evidence implicates abnormalities of autonomic function in ALS including problems with gastrointestinal (GI) motility. GI complaints reported by ALS patients such as constipation, diffuse abdominal pain, and a feeling of fullness or nausea may be attributed to autonomic involvement. Toepfer et al. found delayed gastric emptying in most ALS patients, indicating autonomic dysfunction (Gastrointestinal dysfunction in amyotrophic lateral sclerosis. Amyotrophic Lateral Scl...
This is an exploratory neurophysiological study that will determine the impact of non-invasive brain stimulation on autonomic regulation, with a focus on gastrointestinal function. These studies should provide a basis for future brain-based neurotherapeutic strategies in patients with functional GI disorders.
We are looking to test a novel device in the treatment of Obstructive Sleep Apnea (OSA). Rather than using positive pressure to open the airways, we are testing a device that delivers an auditory tone to affect neuromodulation. We will test its efficacy in treating OSA while minimizing sleep disturbance. As this device is much less cumbersome to wear, we hope this therapy device will also improve compliance with treatment.
Low anterior resection syndrome (LARS) is a complex disorder suffered by patients who undergo rectal resection mainly due to rectal cancer. It is characterized by fecal incontinence, fragmented defecation, constipation, defecatory urgency among others, which induce an impairment in quality of life. LARS treatment armamentarium is scarce and with no long-term relief, being a difficult challenge for surgeons. There is evidence showing that sacral neuromodulation (SNM) improves ...
This prospective one group cohort study seeks to investigate the effects of sacral neuromodulation on urinary urgency, frequency and urge incontinence are maintained after the simulator device is temporarily turned off for a period of four weeks.
The purpose of this study is to examine how the immune systems of HIV-infected patients react to 2 anti-HIV drug combinations.
Therapies involving the immune system have already shown great promise in early clinical trials for the treatment of renal cell carcinoma and melanoma. One of the great challenges now facing this field is to extend these findings to other cancers. Little is currently understood about the nature of the immune response to more common gastrointestinal cancers. The first goal of this proposal is to collect blood and tissue samples from patients with early or late stage gastrointes...
Brief Summary: A randomized double-blinded, sham-controlled, crossover study Condition or Disease: impaired autonomic balance measured by heart rate variability
Patient's immune systems are often damaged by chemotherapy or by CLL. Researchers want to learn if giving T-cells (immune cells) that have been expanded and specially processed in the laboratory (activated) will help CLL patients' immune systems recover after chemotherapy. This may help lower the chance of infections. The goal of this clinical research study is to learn if an activated T-cell infusion, when given with or without lenalidomide, can help to restore patients' im...
The purpose of this study is to measure the prevalence and severity of cardiac autonomic neuropathy (CAN), diabetic autonomic neuropathy (DAN) which in non-diabetics is termed advanced nervous system (ANS) dysfunction, and autonomic dysfunction as well as the overall sympathovagal balance (SB) in the CEFH population of diabetic patients versus non-diabetic patients undergoing elective vitreoretinal surgery.
Sacral neuromodulation is a well-excepted minimally invasive procedure for the treatment of overactive bladder and non-obstructive urinary retention.A tined lead with 4 stimulation electrodes is placed through the third or fourth sacral foramen and stimulates sacral roots in its vicinity. Since the sacral roots are mixed nerves, it is currently still unknown which nerve fibers are stimulated (autonomic vs somatic, afferent vs efferent) and what the mechanism of action is. ...
This is an open-label study to evaluate the safety and efficacy of an anticancer medication (A01) combined with immune cells (IC01) in subjects with advanced Gastrointestinal cancer.
In the presented study, autonomic function as well as risk for atrial fibrillation will be assessed to characterize the relation between risk of atrial fibrillation and autonomic function.
This is a 16-week, prospective, multicenter, double-blind, controlled, randomized study assessing change in psoriasis severity and level of stress in patients with moderate psoriasis treated with ANM. Psoriasis severity and stress levels will be measured at Weeks 0, 2, 8, 12, and 16.
The purpose of this study is to assess the benefits of Percutaneous Neuromodulation Therapy when compared to a reference sham treatment in the treatment of patients who have undergone surgical intervention for chronic low back pain with or without a radiating lower extremity pain component.
Background: Although a small group, special attention has to be given to lower urinary tract (LUT) dysfunctions in spinal cord injury (SCI) patients, as they also suffer under a loss of motor-sensory function and autonomic regulation next to the severe deficiencies in bladder and bowel control. Autonomic dysregulation linked with LUT dysfunction can cause autonomic dysreflexia with life threatening increases in blood pressure and there is still no concept for an early rehabilit...
This is a four arm, patient subtyping and parameter optimisation study for a neuromodulation treatment for tinnitus.
The acoustic neuromodulation trial (ANM-T) is a two-phase, single-site, pilot randomized clinical trial examining the feasibility of completing a larger scale efficacy study of a novel treatment of non-linear modulated acoustic stimuli to reduce anxiety severity in youth with anxiety disorders. The primary objective is to establish the feasibility of a blinded randomized controlled trial of ANM for childhood anxiety disorders.
Sexual dysfunction affects approximately 45% of women with an even greater incidence reported in women with overactive bladder symptoms, despite this there is a lack of FDA approved treatments for sexual dysfunction in this population. While both medical therapy and electrical neuromodulation have been shown to improve urinary function as well as sexual function, there is a dearth of literature about their comparative effectiveness in the latter. The purpose of this study is to...
The purpose of this study is to characterize the link between neurobehavioral measures of the mesolimbic reward system and immune functioning in healthy individuals, via fMRI neurofeedback modulation of mesolimbic reward system, and the consecutive assesment of immune response to Hepatitis B vaccination.
The prevalence of the fibromyalgia is about 10-15% in the European countries. It is unclear the etiology and pathogenesis of the syndrome. Several factors such as dysfunction of the central and autonomic nervous systems, neurotransmitters, hormones, immune system, external stressors, psychiatric aspects, and others seem to be involved. But the symptom commonly expressed by the people who suffer from it is pain. The main goal of the present study is to analyse the effect of the...
The main objectives of the study are to assess (1) patterns of brain activity/connectivity that confers greater cardio-autonomic/emotion regulation, (e.g., heart rate variability, blood pressure reactivity, inflammatory-immune activation, etc.), during rest, mental stress, and anger-related distress, (2) whether changes in breathing pace mitigate task-based effects on cardio-autonomic-immune regulation, and (3) whether these patterns vary as a function of HIV or pre-hypertensiv...
