Introduction: Historically, prehospital care of trauma patients has included nearly universal use of a cervical collar (C-collar) and long spine board (LSB). Due to recent evidence demonstrating harm in using LSBs, implementation of new spinal motion restriction (SMR) protocols in the prehospital setting should reduce LSB use, even among patients with spinal cord injury. Our goal in this study was to evaluate the rates of and reasons for LSB use in high-risk patients-those with hospital-diagnosed spinal cord injury (SCI)-after statewide implementation of SMR protocols.

Methods: Applying data from a state emergency medical services (EMS) registry to a state hospital discharge …

Anterocollis (AC) and retrocollis (RC) are less common cervical dystonia (CD) subtypes that are often under-represented in CD clinical trials. Herein we describe real-world demographics, disease characteristics, and treatment response to onabotulinumtoxinA (onabotA) in AC or RC patients from an observational, multicenter, prospective registry, CD PROBE. After three onabotA treatments, outcomes (CDIP-58, PGIC, CGIC, CD severity, TWSTRS) in patients with predominant AC or RC were compared to torticollis (TC) and all CD subtypes combined. The mean dosages at each treatment ranged from 153.5 to 195.4 U (AC) to 184.0-213.4 U (RC). After treatment, AC and RC patients reported improvements in …

Underrepresentation of racial and ethnic subgroups in cancer clinical trials remains a persistent challenge. Restrictive clinical trial eligibility criteria have been shown to exacerbate this problem. We previously identified that up to 24% of patients treated with standard immunochemotherapy would have been excluded from recent first-line trials in diffuse large B-cell lymphoma (DLBCL) based on 5 laboratory-based criteria. These ineligible patients had worse clinical outcomes and increased deaths related to lymphoma progression, suggesting the potential exclusion of patients who could have benefited most from the novel therapies being evaluated. Using data from the prospectively enrolled Lymphoma Epidemiology Outcomes cohort study, …

Although long-term survival in Rett syndrome (RTT) has been observed, limited information on older people with RTT exists. We hypothesized that increased longevity in RTT would be associated with genetic variants in MECP2 associated with milder severity, and that clinical features would not be static in older individuals. To address these hypotheses, we compared the distribution of MECP2 variants and clinical severity between younger individuals with Classic RTT (under 30 years old) and older individuals (over 30 years old). Contrary to expectation, enrichment of a severe MECP2 variant (R106W) was observed in the older cohort. Overall severity was not different …

INTRODUCTION: Switching disease-modifying therapy (DMT) may be considered for relapsing-remitting multiple sclerosis (RRMS) if a patient's current therapy is no longer optimal. This was particularly important during the recent COVID-19 pandemic because of considerations around immune deficiency and impaired vaccine response associated with B cell-depleting DMTs. This real-world, single-center study aimed to evaluate change or decline in functional ability and overall disease stability in people with RRMS who were switched from B cell-depleting ocrelizumab (OCRE) to diroximel fumarate (DRF) because of safety concern related to the COVID-19 pandemic.

METHODS: Adults with RRMS were included if they had been clinically stable …

Variants in seven genes (LRRK2, GBA1, PRKN, SNCA, PINK1, PARK7 and VPS35) have been formally adjudicated as causal contributors to Parkinson's disease; however, individuals with Parkinson's disease are often unaware of their genetic status since clinical testing is infrequently offered. As a result, genetic information is not incorporated into clinical care, and variant-targeted precision medicine trials struggle to enrol people with Parkinson's disease. Understanding the yield of genetic testing using an established gene panel in a large, geographically diverse North American population would help patients, clinicians, clinical researchers, laboratories and insurers better understand the importance of genetics in approaching Parkinson's …

The rewards that we get from our choices and actions can have a major influence on our future behavior. Understanding how reward biasing of behavior is implemented in the brain is important for many reasons, including the fact that diminution in reward biasing is a hallmark of clinical depression. We hypothesized that reward biasing is mediated by the anterior cingulate cortex (ACC), a cortical hub region associated with the integration of reward and executive control and with the etiology of depression. To test this hypothesis, we recorded neural activity during a biased judgment task in patients undergoing intracranial monitoring for …

BACKGROUND: Deep brain stimulation (DBS) is an established and expanding therapy for treatment-refractory obsessive-compulsive disorder. Previous work has suggested that a white matter circuit providing hyperdirect input from the dorsal cingulate and ventrolateral prefrontal regions to the subthalamic nucleus could be an effective neuromodulatory target.

METHODS: We tested this concept by attempting to retrospectively explain through predictive modeling the ranks of clinical improvement as measured by the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) in 10 patients with obsessive-compulsive disorder who underwent DBS to the ventral anterior limb of internal capsule with subsequent programming uninformed by the putative target tract.

RESULTS: Rank …

A Case Of Hhv-6 Viral Meningitis, Mohammad A. Rattu, Wayne Tamaska

Rowan-Virtua Research Day

Meningitis is the inflammation of the meninges and associated with abnormal cell count in the cerebrospinal fluid (CSF). The lack of bacterial growth in cultures, most commonly referred to as aseptic meningitis, is frequently caused by viruses [2]. Viruses have become more common as the prevalence of bacterial meningitis has decreased secondary to vaccination use, with viral meningitis being the most common form among countries. Viral meningitis will present with fever, headache, photophobia, neck stiffness and nausea and vomiting. Younger children however may not show any signs of meningeal irritation. Viral meningitis is usually self-limiting and with good prognosis; however, …

Rowan-Virtua Research Day

BACKGROUND/PURPOSE

Traumatic brain injury (TBI) is one of the major causes of morbidity in the US [1-4]. Studies suggest TBI patients’ enrollment in a rehabilitation program strongly predicts social reintegration. The structure and outcomes of inpatient rehabilitation programs, including acute and subacute rehabilitation, are not well-delineated [5-7].

DESIGN

A structured review of current literature was conducted. Articles were screened using the search string: (post-traumatic brain injury OR post-TBI OR traumatic brain injury OR TBI) AND (acute rehabilitation OR subacute rehabilitation) AND (outcomes OR functional outcomes) NOT (outpatient OR outpatient populations) NOT (pediatric OR pediatric populations). Articles were limited to 1990 …

Faculty, Staff and Student Publications

DESIGN: Cross-sectional survey.

OBJECTIVE: To evaluate the perceived helpfulness of pharmacological and non-pharmacological interventions and their combinations for neuropathic pain (NeuP) and subcategories of NeuP after spinal cord injury (SCI).

SETTING: Six Spinal Cord Injury Model System Centers.

METHODS: Three hundred ninety one individuals at least one year post traumatic SCI were enrolled. A telephone survey was conducted to determine the pharmacologic and non-pharmacologic treatments used in the last 12 months for each participant's three worst pains, whether these treatments were "helpful", and if currently used, each treatments' effectiveness.

RESULTS: Two hundred twenty participants (56%) reported 354 distinct NeuPs. Pharmacological …

The treatment of epilepsy, the second most common chronic neurological disorder, is often complicated by the failure of patients to respond to medication. Treatment failure with anti-seizure medications is often due to the presence of non-epileptic seizures. Distinguishing non-epileptic from epileptic seizures requires an expensive and time-consuming analysis of electroencephalograms (EEGs) recorded in an epilepsy monitoring unit. Machine learning algorithms have been used to detect seizures from EEG, typically using EEG waveform analysis. We employed an alternative approach, using a convolutional neural network (CNN) with transfer learning using MobileNetV2 to emulate the real-world visual analysis of EEG images by epileptologists. …


Idiopathic Intracranial Hypertension After Abrupt Cessation Of Medication: A Case Report Of Abrupt Glucagon-Like Peptide-1 (Glp-1) Receptor Agonist Cessation And Review Of The Literature, Brittany Heckel Apr 2024

Idiopathic Intracranial Hypertension After Abrupt Cessation Of Medication: A Case Report Of Abrupt Glucagon-Like Peptide-1 (Glp-1) Receptor Agonist Cessation And Review Of The Literature, Brittany Heckel

Department of Jefferson Headache Center Papers and Presentations

PURPOSE OF REVIEW: The purpose of this review is two-fold: (1) to discuss a case report of idiopathic intracranial hypertension (IIH) after abrupt cessation of a glucagon-like peptide-1 (GLP-1) receptor agonist with resultant rapid weight gain and (2) to review the literature regarding the potential role of GLP-1 receptor agonists in the treatment of IIH as well as potential pitfalls.

RECENT FINDINGS: GLP-1 receptor agonists have become widely used to treat obesity. Obesity is a known risk factor for the development of IIH, though the precise pathophysiology is unclear. GLP-1 receptor agonists may help treat IIH by promoting weight loss, …

Objective: To determine if cochlear implant (CI) is safe and effective in patients with radiation therapy (XRT)-induced sensorineural hearing loss and to discuss considerations in this population through a retrospective cohort review, systematic review, and meta-analysis.

Databases reviewed: PubMed, Cochrane Library, and Embase.

Methods: We retrospectively reviewed all CI cases after head and neck (HN) XRT at our institution, noting intraoperative findings, postoperative complications, and hearing outcomes. Change in speech discrimination scores (SDSs) was the primary outcome measure. Systematic review was performed to identify all cases of CI after HNXRT. A meta-analysis was performed to assess SDS change.

Results: The …

OBJECTIVE: Focal to bilateral tonic-clonic seizures (FBTCS) represent a challenging subtype of focal temporal lobe epilepsy (TLE) in terms of both severity and treatment response. Most studies have focused on regional brain analysis that is agnostic to the distribution of white matter (WM) pathways associated with a node. We implemented a more selective, edge-wise approach that allowed for identification of the individual connections unique to FBTCS.

METHODS: T1-weighted and diffusion-weighted images were obtained from 22 patients with solely focal seizures (FS), 43 FBTCS patients, and 65 age/sex-matched healthy participants (HPs), yielding streamline (STR) connectome matrices. We used diffusion tensor-derived STRs …

Racial disparities affect multiple dimensions of epilepsy care including epilepsy surgery. This study aims to further explore these disparities by determining the utilization of invasive neuromodulation devices according to race and ethnicity in a multicenter study of patients living with focal drug-resistant epilepsy (DRE). We performed a post hoc analysis of the Human Epilepsy Project 2 (HEP2) data. HEP2 is a prospective study of patients living with focal DRE involving 10 sites distributed across the United States. There were no statistical differences in the racial distribution of the study population compared to the US population using census data except for …
