A Guide for Aspiring Neurology Educators.

Deans of medical schools have diverse roles and responsibilities. In this article, we use the career development trajectories of neurologists who have become education deans in student affairs and curriculum to offer advice to aspiring clinician educators of all levels and backgrounds. Although their roles differ, the advice they share is universal and essential for the career development of future clinician educators. ANN NEUROL 2024.

Prospective, Multicenter, Controlled Trial of Mobile Stroke Units.

BACKGROUND: Mobile stroke units (MSUs) are ambulances with staff and a computed tomographic scanner that may enable faster treatment with tissue plasminogen activator (t-PA) than standard management by emergency medical services (EMS). Whether and how much MSUs alter outcomes has not been extensively studied. METHODS: In an observational, prospective, multicenter, alternating-week trial, we assessed outcomes from MSU or EMS management within 4.5 hours after onset of acute stroke symptoms. The primary outcome was the score on the utility-weighted modified Rankin scale (range, 0 to 1, with higher scores indicating better outcomes according to a patient value system, derived from scores on the modified Rankin scale of 0 to 6, with higher scores indicating more disability). The main analysis involved dichotomized scores on the utility-weighted modified Rankin scale (≥0.91 or <0.91, approximating scores on the modified Rankin scale of ≤1 or >1) at 90 days in patients eligible for t-PA. Analyses were also performed in all enrolled patients. RESULTS: We enrolled 1515 patients, of whom 1047 were eligible to receive t-PA; 617 received care by MSU and 430 by EMS. The median time from onset of stroke to administration of t-PA was 72 minutes in the MSU group and 108 minutes in the EMS group. Of patients eligible for t-PA, 97.1% in the MSU group received t-PA, as compared with 79.5% in the EMS group. The mean score on the utility-weighted modified Rankin scale at 90 days in patients eligible for t-PA was 0.72 in the MSU group and 0.66 in the EMS group (adjusted odds ratio for a score of ≥0.91, 2.43; 95% confidence interval [CI], 1.75 to 3.36; P<0.001). Among the patients eligible for t-PA, 55.0% in the MSU group and 44.4% in the EMS group had a score of 0 or 1 on the modified Rankin scale at 90 days. Among all enrolled patients, the mean score on the utility-weighted modified Rankin scale at discharge was 0.57 in the MSU group and 0.51 in the EMS group (adjusted odds ratio for a score of ≥0.91, 1.82; 95% CI, 1.39 to 2.37; P<0.001). Secondary clinical outcomes generally favored MSUs. Mortality at 90 days was 8.9% in the MSU group and 11.9% in the EMS group. CONCLUSIONS: In patients with acute stroke who were eligible for t-PA, utility-weighted disability outcomes at 90 days were better with MSUs than with EMS.

Recent US Case of Variant Creutzfeldt-Jakob Disease-Global Implications.

Variant Creutzfeldt-Jakob disease (vCJD) is a rare, fatal prion disease resulting from transmission to humans of the infectious agent of bovine spongiform encephalopathy. We describe the clinical presentation of a recent case of vCJD in the United States and provide an update on diagnostic testing. The location of this patient's exposure is less clear than those in the 3 previously reported US cases, but strong evidence indicates that exposure to contaminated beef occurred outside the United States more than a decade before illness onset. This case exemplifies the persistent risk for vCJD acquired in unsuspected geographic locations and highlights the need for continued global surveillance and awareness to prevent further dissemination of vCJD.

Improving secondary stroke self-care among underserved ethnic minority individuals: a randomized clinical trial of a pilot intervention.

The overall purpose of this study was to pilot a multibehavioral, brief, stroke self-care treatment adapted for implementation with underserved racial/ethnic minority groups and to test the moderating effects of anxiety and depression on engagement in secondary stroke-prevention behaviors. Fifty-two participants were randomized to the secondary stroke prevention (STOP) (N = 27) or usual care (N = 25) group. The STOP program consisted of 3 culturally tailored information sessions and goal-setting activities that were delivered in person by a research assistant. Participants were assessed at baseline and 4-week follow-up for stroke knowledge, exercise, fruit and vegetable consumption, tobacco and alcohol use, and medication adherence (primary outcomes) and anxiety and depression (moderator variables). Between-groups analysis of covariance and logistic multiple regressions revealed significant between-group differences for stroke knowledge, tobacco use and moderating effects between tobacco and anxiety, and improved alcohol use. The STOP program decreased secondary stroke risk factors among underserved racial/ethnic minorities and should be tested in large-scale trials.

False Claims Act and Anti-Kickback Statute: Avoiding Legal Landmines.

Health care entities doing business with the federal government may run afoul of the False Claims Act and Anti-Kickback Statute not only when they directly submit fraudulent claims for government reimbursement but also when they create schemes that manipulate others into submitting (whether knowingly or unknowingly) illegal claims. In recent years, the Department of Justice is deploying these statutes to ensure that electronic health records are built and maintained with appropriate cybersecurity protections.

Protecting Privacy: Health Insurance Portability and Accountability Act of 1996, Twenty-First Century Cures Act, and Social Media.

Advances in electronic health record technology, the ever-expanding use of social media, and cybersecurity sabotage threaten patient privacy and render physicians and health care organizations liable for violating federal and state laws. Violating a patient's privacy is both an ethical and legal breach with potentially serious legal and reputational consequences. Even an unintentional Health Insurance Portability and Accountability Act of 1996 (HIPAA) violation can result in financial penalties and reputational harm. Staying complaint with HIPAA requires vigilance on the part of both individuals with legitimate access to protected health information (PHI) and the organizations handling that PHI.

The Medicolegal and Ethical Dimensions of Physician Prescription Reluctance.

ABSTRACT: This article addresses the potential legal ramifications for neurologists caring for patients with Alzheimer disease (AD) who elect neither to prescribe aducanumab nor to refer patients with AD for treatment with aducanumab. To prevail against a neurologist for failing to prescribe aducanumab or refer for aducanumab treatment, the plaintiff would have to establish that the neurologist's failure to prescribe the medication or refer for treatment was a breach of the standard of care. The standard of care is conceptualized as the generally accepted approach to diagnosing or treating a condition. However, the controversy surrounding the US Food and Drug Administration's (FDA's) approval process for aducanumab (which was based on the drug's efficacy at reducing brain amyloidosis rather than on clinically meaningful efficacy) as well as the American Academy of Neurology (AAN) position statement on aducanumab and the recent decision by the Centers for Medicare & Medicaid Services (CMS) to limit Medicare coverage of the drug and its associated costs to patients enrolled in qualifying clinical trials indicate that aducanumab cannot yet be considered the standard of care for the treatment of AD. Although deciding not to prescribe aducanumab does not violate the standard of care, neurologists treating patients with AD and not recommending this treatment should explain to their patients and their patients' surrogate decision makers why they are not recommending the treatment.

Legal and Ethical Challenges in the Care of the Pregnant Patient After Brain Death.

ABSTRACT: Using two scenarios based on real-life cases reported in the media, this article examines the ethical and legal controversies that arise when a pregnant woman dies based on neurologic criteria while her fetus remains alive. In the first scenario, all parties agreed to maintain physiologic support until a safe delivery could be achieved, whereas in the second scenario the woman's family sought a legal remedy to stop the hospital from continuing to provide physiologic support for the patient and her neurologically devastated fetus.

Neurolymphomatosis of the brachial plexus from atypical primary central nervous system lymphoma lesions: A case report and review of the literature.

Background: Primary central nervous system lymphoma (PCNSL) is an aggressive and extranodal non-Hodgkin lymphoma limited to the neuroaxis. In immunocompetent individuals, PCNSL is more common in older adults and lacks the association with the Epstein-Barr virus found in individuals with AIDS-associated PCNSL. Because the clinical presentation and radiographic findings of PCNSL are highly variable, stereotactic brain biopsy is typically required for definitive diagnosis. High-dose methotrexate, in combination with other chemotherapeutic agents with or without whole brain radiation, is the mainstay of treatment. Case Description: A 70-year-old HIV-negative woman presented with confusion, acute flaccid left arm weakness, and left hand numbness. Head computed tomography without contrast demonstrated a 1 cm hyperdense round lesion in the suprasellar cistern that prompted further evaluation. Gadolinium-enhanced brain magnetic resonance imaging demonstrated enhancing lesions with heterogeneous signal intensity in the suprasellar, pineal, and right periatrial regions that did not explain the limb weakness and numbness. Serum and cerebrospinal fluid (CSF) studies were unrevealing, and a diagnosis of PCNSL was made following stereotactic biopsy. The patient's liver cirrhosis precluded chemotherapy, but treatment with whole-brain radiation was pursued. Conclusion: The myriad clinical presentations and insidious course of PCNSL contribute to diagnostic difficulties, delays in treatment, and poor outcomes. Stereotactic brain biopsy is the primary method of PCNSL diagnosis since malignant cells are typically not detected in CSF. PCNSL should be considered in the differential diagnosis when immunocompetent elderly patients present with multiple intracranial lesions, even in the presence of lower motor neuron findings.

Connecting Cohorts to Diminish Alzheimer's Disease (CONCORD-AD): A Report of an International Research Collaboration Network.

Longitudinal observational cohort studies are being conducted worldwide to understand cognition, biomarkers, and the health of the aging population better. Cross-cohort comparisons and networks of registries in Alzheimer's disease (AD) foster scientific exchange, generate insights, and contribute to the evolving clinical science in AD. A scientific working group was convened with invited investigators from established cohort studies in AD, in order to form a research collaboration network as a resource to address important research questions. The Connecting Cohorts to Diminish Alzheimer's Disease (CONCORD-AD) collaboration network was created to bring together global resources and expertise, to generate insights and improve understanding of the natural history of AD, to inform design of clinical trials in all disease stages, and to plan for optimal patient access to disease-modifying therapies once they become available. The network brings together expertise and data insights from 7 cohorts across Australia, Europe, and North America. Notably, the network includes populations recruited through memory clinics as well as population-based cohorts, representing observations from individuals across the AD spectrum. This report aims to introduce the CONCORD-AD network, providing an overview of the cohorts involved, reporting the common assessments used, and describing the key characteristics of the cohort populations. Cohort study designs and baseline population characteristics are compared, and available cognitive, functional, and neuropsychiatric symptom data, as well as the frequency of biomarker assessments, are summarized. Finally, the challenges and opportunities of cross-cohort studies in AD are discussed.

Interprofessional Internet Consultations: The Potential Benefits and Perils of eConsults.

ABSTRACT: This article addresses the question of whether neurologists performing interprofessional internet consultations, known as eConsults, face the same malpractice liability as for face-to-face patient care. Because the physician-patient relationship is usually unambiguous, determining the scope of legal liability arising from these relatively new approaches to patient care requires understanding the types of interactions courts have found to establish a patient-physician relationship.

False Claims Act Overview and Implications for Neurologists.

ABSTRACT: The US Department of Health and Human Services Office of the Inspector General identifies the five most important federal fraud and abuse laws that are most applicable to physicians: the False Claims Act, the Anti-Kickback Statute, the Physician Self-Referral Law (Stark Law), the Exclusion Authorities, and the Civil Monetary Penalties LawThe False Claims Act is the US government's primary tool for combating fraud perpetrated through the filing of false claims for federal government reimbursement. Neurologists and companies serving the needs of neurologic patients have not been immune from False Claims Act-related legal action. This article provides an overview of the False Claims Act, uses real-life neurologic cases to illustrate the range of False Claims Act violations and recoveries, and offers some practical compliance suggestions.

Sectional neuroanatomy of the pelvic floor.

This is the sixth in a series of articles on the spine. The first 5 reviewed the sectional anatomy of the cervical, thoracic, and lumbosacral spines. This paper will review both the male and female pelves. Procedures performed in the pelvis include electromyography of the anal sphincter, pudendal and sacral nerve stimulator implants, and botulinum toxin type A injections into the prostate, the bladder, the urethra, and the anus. Complications from these procedures are rare. Electromyography in this region is particularly uncomfortable. Botulinum toxin type A denervation may result in local effects such as incontinence or urinary retention or rarely remote effects such as limb weakness. Neurostimulators may get infected or may fail. This article provides anatomically accurate schematics of innervations of the pelvis that can be used to interpret magnetic resonance images of muscles and nerves in the pelvic floor region. Cross-sectional schematics of the male and female pelves were drawn as they appear on imaging projections. The relevant nerves were color coded. The muscles and the skin surfaces were labeled and assigned the color of the appropriate nerves. An organized comprehensive map of the motor innervation of both the male and female pelves allows the physician to increase the accuracy and efficacy of interventional procedures. This anatomic map could also assist the electromyographer in correlating the clinical and electrophysiologic findings on magnetic resonance images.

A report of fetal demise during therapeutic hypothermia after cardiac arrest.

BACKGROUND: Therapeutic hypothermia is becoming the standard-of-care for coma following out-of-hospital cardiac arrest. Pregnancy has been considered a contraindication for therapeutic hypothermia. METHODS: Case report. RESULTS: A 44-year-old woman presented after a witnessed out-of-hospital ventricular fibrillation cardiac arrest. She remained comatose upon hospital admission and was treated with induced hypothermia via surface cooling pads. An intrauterine pregnancy of 20 weeks gestation was discovered on admission. One day after admission, a stillborn fetus was spontaneously delivered. The patient made a good neurologic recovery and now lives at home with her family. CONCLUSION: During pregnancy, beneficence toward the pregnant woman must be the primary ethical guideline in emergent, life-threatening situations. Pregnancy should not be a contraindication to therapeutic hypothermia following cardiac arrest.

Criminal Culpability for Acts Committed During a Possible Episode of REM Sleep Behavior Disorder.

Rapid eye movement (REM) sleep behavior disorder (RBD) may result in a patient injuring a bed partner while acting out a dream. This article examines the complexities associated with RBD as a criminal defense strategy as well as the legal implications for physicians and their duty to patients and their families to mitigate risks associated with possible injuries related to RBD.

Legal Liability Associated With rtPA Administration and Surrogate Decision Makers.

Stroke is one of the most common conditions neurologists treat in emergency situations. This article examines the issues of surrogate decision makers and the physician's potential legal liability in the context of the administration or nonadministration of recombinant tissue plasminogen activator (rtPA) in a common emergency department scenario.

Cytokine Storm in COVID-19-Immunopathological Mechanisms, Clinical Considerations, and Therapeutic Approaches: The REPROGRAM Consortium Position Paper.

Cytokine storm is an acute hyperinflammatory response that may be responsible for critical illness in many conditions including viral infections, cancer, sepsis, and multi-organ failure. The phenomenon has been implicated in critically ill patients infected with SARS-CoV-2, the novel coronavirus implicated in COVID-19. Critically ill COVID-19 patients experiencing cytokine storm are believed to have a worse prognosis and increased fatality rate. In SARS-CoV-2 infected patients, cytokine storm appears important to the pathogenesis of several severe manifestations of COVID-19: acute respiratory distress syndrome, thromboembolic diseases such as acute ischemic strokes caused by large vessel occlusion and myocardial infarction, encephalitis, acute kidney injury, and vasculitis (Kawasaki-like syndrome in children and renal vasculitis in adult). Understanding the pathogenesis of cytokine storm will help unravel not only risk factors for the condition but also therapeutic strategies to modulate the immune response and deliver improved outcomes in COVID-19 patients at high risk for severe disease. In this article, we present an overview of the cytokine storm and its implications in COVID-19 settings and identify potential pathways or biomarkers that could be targeted for therapy. Leveraging expert opinion, emerging evidence, and a case-based approach, this position paper provides critical insights on cytokine storm from both a prognostic and therapeutic standpoint.

Procedure-oriented sectional anatomy of the shoulder.

This is the first in a series of papers on procedure-oriented joint anatomy. This paper will review anatomy of the shoulder joint and focus on non-imaging-guided procedures. Needle procedures of the shoulder include glenohumeral, subacromial, and acromioclavicular joint injections; electromyography; trigger point and other intramuscular injections; bicipital tendon sheath injection; suprascapular nerve blocks; and botulinum toxin injections. The accuracy of these non-imaging-guided procedures is reviewed. Complications of these procedures include infection, damage to tendon, and local or systemic response to medication. This paper provides anatomically accurate schematics of the shoulder anatomy relevant to needle procedures. Cross-sectional schematics of the shoulder were drawn as they appear on axial and sagittal projections. Superficial and deep landmarks are highlighted and sources of potential complications. The schematics allow for safer and more accurate non-image-guided needle procedures in the shoulder region.

Traumatic brain injury may increase the risk for frontotemporal dementia through reduced progranulin.

Frontotemporal lobar degeneration with TAR-DNA-binding protein inclusions (FTLD-TDP) is the most common pathological subtype of frontotemporal dementia (FTD). Mutations leading to a loss of function in the progranulin gene (PGRN) are the most common known cause of FTLD-TDP. In agreement with the proposed loss of function disease mechanism, several groups have reported decreased plasma levels of PGRN in patients carrying PGRN mutations compared to individuals without PGRN mutations. We propose that traumatic brain injury (TBI), an environmental factor, may also increase the risk of FTD by altering PGRN metabolism. TBI may lead to an increase in the central nervous system levels of microglial elastases, which proteolyze PGRN into proinflammatory products called granulins causing a reduction in PGRN levels. Hence, inhibiting microglial activation may have an important implication for the prevention of FTD in patients with TBI.

Liability and Failure to Warn a Patient.

This medicolegal article examines a physician's liability when he or she has knowledge of adverse effects associated with a prescription medication and suggests ways to mitigate that liability risk. The article also discusses the circumstances under which pharmaceutical companies face liability for side effects such as tardive dyskinesia.
