Manf Is Neuroprotective Against Ethanol-Induced Neurodegeneration Through Ameliorating Er Stress, Yongchao Wang, Wen Wen, Hui Li, Marco Clementino, Hong Xu, Mei Xu, Murong Ma, Jacqueline A. Frank, Jia Luo

Pharmacology and Nutritional Sciences Faculty Publications

Fetal alcohol spectrum disorders (FASD) are a spectrum of developmental disorders caused by prenatal alcohol exposure. Neuronal loss or neurodegeneration in the central nervous system (CNS) is one of the most devastating features in FASD. It is imperative to delineate the underlying mechanisms to facilitate the treatment of FASD. Endoplasmic reticulum (ER) stress is a hallmark and an underlying mechanism of many neurodegenerative diseases, including ethanol-induced neurodegeneration. Mesencephalic astrocyte-derived neurotrophic factor (MANF) responds to ER stress and has been identified as a protein upregulated in response to ethanol exposure during the brain development. To investigate the role of MANF in …

Weinberg, Ahmad Sweid, Ashlee Asada, Rawad Abbas, Keenan Piper, Daniel Joffe, Michael Reid Gooch, Stavropoula Tjoumakaris, Pascal Jabbour, Robert H. Rosenwasswer, Hekmat Zarzour

Department of Neurosurgery Faculty Papers

Objective: To present intraoperative observations that when recognized may facilitate the identification of patients at high risk of MT recanalization failure. We illustrate 4 cases of successful recanalization via rescue treatment with balloon angioplasty and/or stenting when such observations were noted. We also discuss the role of intracranial atherosclerotic disease in recanalization failure.

Patients and methods: We conducted a retrospective review of a prospectively maintained database for 450 stroke patients and identified 122 patients who underwent MT that failed to achieve recanalization. Operative notes were reviewed, and intraoperative nuances were discussed amongst neurointerventionalists.

Results: Intraoperative observations that may suggest a …

Focal Cortical Dysplasia With Prolonged Ictal Asystole, A Case Report, Ahmad Wali, Fowzia Siddiqui

Section of Neurology

Introduction: Cortical dysplasia carries significant morbidities such as seizures and delayed milestones. Focal cortical dysplasia (FCD) causes refractory epilepsy with various seizure types depending on the location and extent of the dysplasia. FCD in the temporal region and the insular cortex may cause ictal bradycardia (IB) and ictal asystole (IA). Video EEG (VEEG) with simultaneous EKG recording can better diagnose these cardiac abnormalities in FCD. We describe a case of refractory epilepsy. The patient's clinical seizures were usually followed by syncope. VEEG revealed frequent seizures some of which were associated with prolonged ictal asystole.
Results: A 15 years old female …

A Signal Detection Framework For Evaluating The Effects Of Feedback On Stroke Recognition, Jordan D. Bailey

Dissertations

The impact of stroke on the lives of individuals and the healthcare system is considerable. Damage from stroke can be reduced if the treatment is administered at the appropriate time so early recognition is essential. One problem is that strokes present in a variety of ways that sometimes do not fit into the Facial drooping, Arm weakness, Speech difficulties and Time (FAST; American Heart Association, 2019) acronym. Signal detection is one way to measure decision making under conditions of uncertainty (e.g., discriminating stroke symptoms and risk factors from other symptoms, and non-risk factors). The methodology also allows us to consider …

Neural Correlates Of Social Pain In Psychological Disorders: Implications For Educational Settings, Skye E. Johnson

Honors Projects

Pain has long been defined as a multidimensional construct; in past research, not only have the physical and sensory aspects of pain been investigated, but also the cognitive and emotional aspects, which include the experience of social pain. This experience is generally accepted to be very distressing and can have adverse effects on one's mental health, especially for those with neurological disorders. In my paper, I examine the effects of social pain on brain activity in individuals with autism spectrum disorder (ASD) and borderline personality disorder (BPD) as compared to those who are neurotypical. This research finds that while neurotypical …

METHODS A cross-sectional study was carried out between December 2019 and June 2020 (six months) including 66 migraine patients between 18 …

What's Going On With The Spine? Evaluation Of Alternative Sensorimotor Degeneration Post-Stroke, Sravani Mannuru, Sarvani Uppati, Kelsey Baker

MEDI 9331 Scholarly Activities Clinical Years

Stroke is a leading cause of long-term disability in the United States. Previous research has shown a strong correlation between damage to the corticospinal tract (CST) and motor deficits in post-stroke patients. However, recent research suggests that other sensorimotor pathways (rubrospinal tract, medial reticulospinal tract) are damaged after stroke and may also contribute to motor dysfunction. Here, we will review current research suggesting that alternate sensorimotor pathways are involved in post-stroke motor dysfunction and outline possible avenues for future research.

Acute Ischemic Stroke Treatment Barriers In Pakistan, Saima Ahmad, Umair Rashid, Ossama Mansour, Sohail Akhtar

Pakistan Journal of Neurological Sciences (PJNS)

Worldwide stroke is the second most common cause of death and the third most common cause of disability (1). No large-scale epidemiological studies are available to determine the true incidence of stroke in Pakistan. There is only one published stroke prevalence study which was conducted in a community residing in Karachi, the prevalence was 4.8%, however the results of the study should be interpreted with caution as a non-validated questionnaire was used. (2). Another community-based survey suggested as estimated 21.8% prevalence of stroke in an urban slum of Karachi (3). These studies although published in local journals but do not …

Longitudinally Extensive Transverse Myelitis: A Sub-Saharan Conundrum, Antonina Obayo, Sylvia Mbugua, Sayed Karar

Internal Medicine, East Africa

Spinal cord schistosomiasis is a rare, underdiagnosed manifestation of schistosomiasis. We present the case of a 36-year-old male who presented to our institution with a one-week history of low back pain with rapidly progressive lower limb weakness, loss of sensation, and flaccid paraparesis. An MRI of the spine showed a longitudinally extensive transverse myelitis from T6 to L1, with enhancement at the cauda equina region. Further review of the images and serological tests eventually led to diagnosis of spinal schistosomiasis. He was treated with praziquantel and high-dose steroids, with minimal improvement in his symptoms.

Network-Level Mechanisms Underlying Effects Of Transcranial Direct Current Stimulation (Tdcs) On Visuomotor Learning, Pejman Sehatpour, Clément Dondé, Matthew J. Hoptman, Johanna Kreither, Devin Adair, Elisa Dias, Blair Vail, Stephanie Rohrig, Gail Silipo, Javier Lopez-Calderon, Antigona Martinez, Daniel C. Javitt

Publications and Research

Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation approach in which low level currents are administered over the scalp to influence underlying brain function. Prevailing theories of tDCS focus on modulation of excitation-inhibition balance at the local stimulation location. However, network level effects are reported as well, and appear to depend upon differential underlying mechanisms. Here, we evaluated potential network-level effects of tDCS during the Serial Reaction Time Task (SRTT) using convergent EEG- and fMRI-based connectivity approaches. Motor learning manifested as a significant (p <.0001) shift from slow to fast responses and corresponded to a significant increase in beta-coherence (p <.0001) and fMRI connectivity (p <.01) particularly within the visual-motor pathway. Differential patterns of tDCS effect were observed within different parametric task versions, consistent with network models. Overall, these findings demonstrate objective physiological effects of tDCS at the network level that result in effective behavioral modulation when tDCS parameters are matched to network-level requirements of the underlying task.

Low Cognitive Function Is Associated With Reduced Functional Fitness Among Community-Dwelling Older Adults, Michelle Gray, Joshua Gills, Jordan Glenn, Erica Madero, Aidan Hall, Nami Fuseya, Jennifer Vincenzo, Nick Bott

Health, Human Performance and Recreation Faculty Publications and Presentations

Among older adults over 70, 22-30% report difficulty performing at least one activity of daily living (ADL). While the precipitants of ADL decline are multifactorial, over 50% of cognitively impaired adults require assistance with ADLs. The exact relationship between cognitive and functional decline remains unknown, but it is important to understand their relationship. Eighty-three older adults (80.9 + 5.4 years) enrolled in this study and completed functional fitness and cognitive assessments. Functional fitness assessments included: Short Physical Performance Battery (SPPB), 10-meter walk, dual-task, and power chair stand (average and peak). Cognition was assessed using the Montreal Cognitive Assessment (MoCA) and …

A Narrative Review Of Targeted Therapy In Meningioma, Pituitary Adenoma, And Craniopharyngioma Of The Skull Base., Nina L. Martinez, Omaditya Khanna, Christopher J. Farrell

Department of Neurosurgery Faculty Papers

Management of solid tumors involving the skull base are primarily managed with surgery and radiation, though proximity to important vascular and neuroanatomic structures often limit the extent of resection and permissible radiation dose. Meningiomas are the most common primary brain tumor in adults, and although the majority of skull base meningiomas are low-grade, their location in proximity to critical anatomical structures precludes aggressive surgical resection, and larger tumors are often resistant to radiation treatment. In patients with clinically aggressive, unresectable meningiomas, several molecular biomarkers of angiogenesis, as well as genetic mutations (SMO, AKT1, PIK3CA, KLF4, POLR2, SMARCE1, and TRAF7), have …

Inflammatory Myopathies: Update On Diagnosis, Pathogenesis And Therapies, And Covid-19-Related Implications., Marinos C. Dalakas

Department of Neurology Faculty Papers

The inflammatory myopathies constitute a heterogeneous group of acquired myopathies that have in common the presence of endomysial inflammation. Based on steadily evolved clinical, histological and immunopathological features and some autoantibody associations, these disorders can now be classified in five characteristic subsets: Dermatomyositis (DM) Polymyositis (PM), Necrotizing Autoimmune Myositis (NAM), Anti-synthetase syndrome-overlap myositis (Anti-SS-OM), and Inclusion-Body-Myositis (IBM). Each inflammatory myopathy subset has distinct immunopathogenesis, prognosis and response to immunotherapies, necessitating the need to correctly identify each subtype from the outset to avoid disease mimics and proceed to early therapy initiation. The review presents the main clinicopathologic characteristics of each subset …
