Purpose To report 36-month outcomes and subgroup analysis of the ABRE Study evaluating safety effectiveness Abre venous self-expanding stent system for treatment symptomatic iliofemoral outflow obstruction disease. Methods The was a prospective, multicenter, non-randomized study that enrolled implanted stents in 200 participants (mean age 51.5±15.9 years 66.5% women) with at 24 global sites. Outcomes assessed through 36 months included patency, major adverse events, migration, fracture,...
Antisaccades are thought to involve higher level inputs from neural centers involved in rapid eye movement inhibition and control. Previous work has demonstrated that performance on the antisaccade task can help assessment of injury acute and/or chronic mild traumatic brain (mTBI). In this exploratory study, we performed cross-sectional longitudinal comparisons movement, followed by correlations with assessments symptom burden, diffusion tensor imaging, a neuropsychological test response...
The objective was to determine headache patients' knowledge, prevalence of use and perceived effectiveness complementary alternative medicine. Seventy-three patients with syndromes attending a head neck pain clinic were interviewed using standardized questionnaire. Alternative medical therapies used by 85% surveyed for the relief their pain. In 60%, have benefit. Almost 100% familiar one or more presented treatments. Eighty-eight per cent at least treatments be an effective remedy Exposure...
Smooth pursuit eye movements are guided largely by retinal-image motion. To compensate for neural conduction delays, the brain employs a predictive mechanism to generate anticipatory that precedes target motion (E. Kowler, 1990). A critical question interpreting signals recorded during concerns how this is interfaced with sensorimotor processing. It has been shown predictor not simply turned-off randomization because velocity remains when randomized Kowler & S. McKee, 1987; G. W. Kao M. J....
Objective We conducted a neuroimaging analysis to understand the neuroanatomical correlates of gray matter loss in group mild cognitive impairment and early Alzheimer's disease patients who developed delusions. Methods With data collected as part Disease Neuroimaging Initiative, we voxel‐based morphometry determine areas change same Initiative participants, before after they Results identified 14 voxel clusters with significant decrease patient scans post‐delusional onset, correcting for...
The purpose of this survey is to evaluate the extent health insurance coverage for complementary and alternative medicine (CAM) within one region in United States, a study prompted by increased utilization CAM.Prospective telephone interview representatives.A contiguous three-state area (New York, New Jersey, Connecticut) North-east.Almost all insurers surveyed cover chiropractic services. Less than half reimburse acupuncture, usually chronic pain management. Coverage massage therapy minimal...
Objectives: Grey matter atrophy in the right hemisphere has been shown to be more severe dementia patients with delusions, suggesting a neuroanatomical localization that may pertinent impending neurodegeneration. Delusional symptoms arise when these areas reduces regulatory functions of hemisphere, tandem asymmetric neuropathology left hemisphere. We hypothesized delusional either amnestic mild cognitive impairment (MCI) or early Alzheimer Disease (AD) would experience pronounced grey...
Although the King-Devick (K-D) test has been used frequently in assessing sports related concussion early after injury, its characteristics over time injury and patients with prolonged persistent symptoms are unknown. The purpose of this paper was to: evaluate ability K-D Test to distinguish seen from those persisting more than 3 months compared controls, assess changes times concussion, determine relationship Stroop Color Word scores. We performed cross-sectional comparisons recent...
Artificial neural networks (ANNs) have shown considerable promise as decision support tools in medicine, including neurosurgery. However, their use concussion and postconcussion syndrome (PCS) has been limited. The authors explore the value of using an ANN to identify patients with concussion/PCS based on antisaccade performance.
Motor learning and pain are important factors influencing rehabilitation. Despite being mostly studied independently from each other, interactions exist between them in the context of spinal cord injury, whether to or body. Ongoing recent past episodes nociceptive activity can prevent motor spinalized rats. In intact animals, it has been proposed that supraspinal could counter repressive effect nociception on system plasticity, but this not yet verified behavioral conditions. The aim study...
Abstract Paired associative stimulation (PAS) has been explored in humans as a noninvasive tool to drive plasticity and promote recovery after neurologic insult. A more thorough understanding of PAS-induced is needed fully harness it clinical tool. Here, we tested the efficacy PAS with multiple interstimulus intervals an awake rat model study principles plasticity. Using chronically implanted electrodes motor cortex forelimb, parameters effectively We assessed changes corticomotor...
Background: Pupillometry, the measurement of pupil response dynamics via pupillary light reflex, is seldom used in assessment mild traumatic brain injury (mTBI). We hypothesized that there would be quantifiable differences detailed measurements patients with acute and chronic mTBI. Methods: conducted 49 bilateral pupillometry measurements, mTBI at 1-week (N=11), 2-4w (N=9), 3-7mo post-injury (N=3); 14 persistent post-traumatic symptoms (PTS) once, healthy controls across a first visit (N=7)...
Background Concussion is an injury that occurs in non-sporting and sporting environments. To determine improved clinical methods for identifying this injury, it important to develop understand how the impact event results quantifiable differences brain functioning—functioning has been quantified past using saccadic measures. The purpose of research was examine relationships between oculomotor deficits, specifically antisaccade responses, biomechanics a concussion. Methods Participants...
Abstract Paired Associative Stimulation (PAS) has been explored in humans as a non-invasive tool to drive plasticity and promote recovery after neurological insult. A more thorough understanding of the phenomenon PAS-induced is needed fully harness it clinical tool. Here, we tested PAS model awake rats order study principles associative plasticity. Using chronically implanted electrodes motor cortex forelimb, parameters effectively change corticomotor excitability, assessed using closed...
Assessment of corticospinal excitability (CSE) is an essential component experiments designed to induce or study neuronal plasticity in the motor system. Common examples are paired associative stimulation (PAS), theta-burst (TBS), intensive training, any methods aimed at potentiating corticomotor system hope promoting better recovery after neurological insult. To date, rodent models CSE assessment have mostly been completed under anaesthesia, which greatly affects level CSE, as well...
