1. A Study to Evaluate Endoscopic Endonasal Skull Base Surgery and Pituitary Surgery Quality of Life

   Rochester, Minn.

   The objectives of this study are to:

   • • Measure the short and long-term overall and nasal-specific quality of life (QOL) impact of patients undergoing Endoscopic Endonasal Skull Base Surgery (EESBS) for pituitary and sellar lesions.
     • Determine the relative difference in QOL impact of EESBS for patients undergoing surgery for functional and nonfunctional pituitary adenomas.
     • Generate baseline data to development and validate a site-specific endoscopic-specific comprehensive QOL for EESBS.
     • Particular tumors of interest include pituitary tumors, Rathke’s cleft cysts, craniopharyngiomas, clival chordomas and chondrosarcomas.
     • Specific QOL aims focus on olfaction (sense of smell), gustation (sense of taste) and nasal function.

    

    

2. Carotid Revascularization and Medical Management for Asymptomatic Carotid Stenosis Trial - Hemodynamics (CREST-H)

   Rochester, Minn., Jacksonville, Fla.

   We aim to determine whether cognitive impairment attributable to cerebral hemodynamic impairment in patients with high-grade asymptomatic carotid artery stenosis is reversible with restoration of flow. To accomplish this aim CREST-H will add on to the NINDS-sponsored CREST-2 trial (parallel, outcome-blinded Phase 3 clinical trials for patients with asymptomatic high-grade carotid artery stenosis which will compare carotid endarterectomy plus intensive medical management (IMM) versus IMM alone (n=1,240), and carotid artery stenting plus IMM versus IMM alone (n=1,240) to prevent stroke and death). CREST-H addresses the intriguing question of whether cognitive impairment can be reversed when it arises from abnormal cerebral hemodynamic perfusion in a hemodynamically impaired subset of the CREST-2 -randomized patients. We will enroll 500 patients from CREST-2, all of whom receive cognitive assessments at baseline and yearly thereafter. We anticipate identifying 100 patients with hemodynamic impairment as measured by an inter-hemispheral MRI perfusion "time to peak" (TTP) delay on the side of stenosis. Among those who are found to be hemodynamically impaired and have baseline cognitive impairment, the cognitive batteries at baseline and at 1 year will determine if those with flow failure who are randomized to a revascularization arm in CREST-2 will have better cognitive outcomes than those in the medical-only arm compared with this treatment difference for those who have no flow failure. We hypothesize that hemodynamically significant "asymptomatic" carotid disease may represent one of the few examples of treatable causes of cognitive impairment. If cognitive decline can be reversed in these patients, then we will have established a new indication for carotid revascularization independent of the risk of recurrent stroke.

3. A Study to Evaluate Sex Differences in Multiple Sclerosis Spectrum of Demyelinating Disorders

   Rochester, Minn.

   The purposes of this study are to explore the association between female sex, reproductive history and clinical phenotypic variability in multiple sclerosis (MS), to explore the association between female sex, reproductive history and radiologic phenotypic variability in MS, and to explore the association between female sex, genetic and environmental interactions in MS.

    

4. A Study to Analyze NMS-03305293 and Temozolomide in Adult Patients with Recurrent Glioblastoma

   Rochester, Minn., Jacksonville, Fla., Scottsdale/Phoenix, Ariz.

   The objectives of this study are to determine the Maximum Tolerated Dose (MTD) and the Recommended Phase 2 Dose (RP2D) of NMS-03305293 in combination with temozolomide (TMZ) in patients with diffuse gliomas at first relapse (Phase I),  and to determine the antitumor effectiveness of the combination of NMS-03305293 and TMZ in patients with isocitrate dehydrogenase (IDH) wild type glioblastoma at first relapse as measured by the 6-month Progression Free Survival (PFS) rate (Phase II).

5. A Study of Pyridostigmine in Postural Tachycardia Syndrome

   Rochester, Minn.

   This is a 3-day study comparing pyridostigmine versus placebo in the treatment of postural tachycardia syndrome (POTS). The researchers expect pyridostigmine to improve tachycardia and stabilize blood pressure.

6. A Study of Factors That Predispose, Promote, and Perpetuate Post-Traumatic Dizziness

   Rochester, Minn.

   The purpose of this study is to investigate whether recent, groundbreaking discoveries about key pathophysiologic processes that drive chronic dizziness in patients without traumatic brain injury (TBI9,10) are applicable to patients with post-mTBI vestibular disability. We expect the results of this project to have practical clinical and research applications, providing novel data for two future steps:

7. A Study of Molecular Anatomic Imaging Analysis of Tau, the Primary Pathological Protein in Progressive Supranuclear Palsy

   Rochester, Minn.

   The purpose of this study is to learn more about the distribution of the pathological protein tau in the living brains of patients with Progressive Supranuclear Palsy (PSP).

8. A Study of Nervous System Involvement of Coccidioidomycosis at Mayo Clinic Hospital in Arizona

   Scottsdale/Phoenix, Ariz.

   The purpose of this study is to gain a better understanding of the presentation, diagnostics, disease course and treatment variations, as well as the factors that may influence features of neuro-invasive Coccidioidomycosis. 

9. A Study to Assess Neuroinflammation in Epileptic Tissue Immediately Prior to Surgical Resection Using Intraoperative Brain Microdialysis

   Rochester, Minn.

   The purpose of this study is to measure the space and time characteristics of inflammatory mediator release in response to induced epileptiform activity in ASD-resistant patients.

10. A Study of the Thalamus Using Deep Electrode EEG to Better Understand its Participation in the Beginning or Spreading of Seizures

    Rochester, Minn.

    The purpose of this study is to assess the thalamus area of the brain using stereotactic electroencephalography (an EEG with deep electrode placement inside the brain) to better understand its role in the starting and spreading of epileptic seizure activity.
