Doctor-Should I get the COVID-19 vaccine? Infection and immunization in individuals with neuromuscular disorders.

The clinical course of neuromuscular disorders (NMDs) can be affected by infections, both in immunocompetent individuals, and in those with reduced immunocompetence due to immunosuppressive/immunomodulating therapies. Infections and immunizations may also trigger NMDs. There is a potential for reduced efficacy of immunizations in patients with reduced immunocompetence. The recent vaccination program for coronavirus disease-2019 (COVID-19) raises several questions regarding the safety and efficacy of this vaccine in individuals with NMDs. In this Practice Topic article, we address the role of vaccine-preventable infections in NMDs and the safety and efficacy of immunization in individuals with NMDs, with emphasis on vaccination against COVID-19.

Quality measures in electrodiagnosis: Carpal tunnel syndrome-An AANEM Quality Measure Set.

Carpal tunnel syndrome (CTS) is a common neuromuscular condition and a major cause of work-related disability. As healthcare in the United States transitions toward a value-based system from fee-for-service, quality measures assume importance in the evaluation of care provided. This report from the American Association of Neuromuscular & Electrodiagnostic Medicine Quality Improvement Committee provides an introduction to quality measures and outlines a quality measurement set for the electrodiagnosis of CTS. The measures attempt to standardize technical requirements for electrodiagnostic (EDX) studies of CTS, the criteria for diagnosing median neuropathy at the wrist and assessing its severity, and the role of operative EDX testing. The assumption is that implementation of these measures will improve the accuracy of CTS diagnosis when EDX is performed, help exclude mimics, and, therefore, improve care of patients with CTS with the ultimate goal of improving outcomes. Postimplementation assessment of outcomes will refine these measures.

Medical Student Perceptions of the Learning Environment in Medical School Change as Students Transition to Clinical Training in Undergraduate Medical School.

Phenomenon: The learning environment is the physical, social, and psychological context in which a student learns. A supportive learning environment contributes to student well-being and enhances student empathy, professionalism, and academic success, whereas an unsupportive learning environment may lead to burnout, exhaustion, and cynicism. Student perceptions of the medical school learning environment may change over time and be associated with students' year of training and may differ significantly depending on the student's gender or race/ethnicity. Understanding the changes in perceptions of the learning environment related to student characteristics and year of training could inform interventions that facilitate positive experiences in undergraduate medical education. APPROACH: The Medical School Learning Environment Survey (MSLES) was administered to 4,262 students who matriculated at one of 23 U.S. and Canadian medical schools in 2010 and 2011. Students completed the survey at the end of each year of medical school as part of a battery of surveys in the Learning Environment Study. A mixed-effects longitudinal model, t tests, Cohen's d effect size, and analysis of variance assessed the relationship between MSLES score, year of training, and demographic variables. FINDINGS: After controlling for gender, race/ethnicity, and school, students reported worsening perceptions toward the medical school learning environment, with the worst perceptions in the 3rd year of medical school as students begin their clinical experiences, and some recovery in the 4th year after Match Day. The drop in MSLES scores associated with the transition to the clinical learning environment (-0.26 point drop in addition to yearly change, effect size = 0.52, p < .0001) is more than 3 times greater than the drop between the 1st and 2nd year (0.07 points, effect size = 0.14, p < .0001). The largest declines were from items related to work-life balance and informal student relationships. There was some, but not complete, recovery in perceptions of the medical school learning environment in the 4th year. Insights: Perceptions of the medical school learning environment worsen as students continue through medical school, with a stronger decline in perception scores as students' transition to the clinical learning environment. Students reported the greatest drop in finding time for outside activities and students helping one another in the 3rd year. Perceptions differed based on gender and race/ethnicity. Future studies should investigate the specific features of medical schools that contribute most significantly to student perceptions of the medical school learning environment, both positive and negative, to pinpoint potential interventions and improvements.

Bridge to M4 (B2M4): An innovative residency application preparation curriculum.

BACKGROUND: The medical residency application process is daunting, time-consuming, and variable, making mentorship in preparation for this process important. In light of changes to the residency application process due to the COVID-19 pandemic, medical students identified a need to create a formal residency application preparation curriculum. The curriculum focused on reflection, while also furthering professional development and preparing for the nuances of the residency application cycle through structured advising. APPROACH: Bridge to M4 (B2M4) included reflective activities to help guide curriculum vitae (CV) refinement, personal and professional values clarification, residency program exploration, elevator pitch formation, personal statement development, mentor identification, guidance on requesting letters of recommendation, and virtual residency interview preparation. EVALUATION: The B2M4 elective first took place in June 2020 with 36 rising fourth year students enrolled. Perceived effectiveness of the curriculum was assessed by having student cohorts evaluate the importance of the CV, personal statement, general preparation, and residency program selection before and after the course. Student feedback was reviewed with content analysis, which highlighted the usefulness of a structured residency preparation course that was rooted in reflection and incorporated faculty mentorship and feedback. IMPLICATIONS: This student-driven, innovative curricular design provided students the opportunity to prepare for the residency application process through reflective activities including values clarification, strengths identification, and goal setting. B2M4 demonstrates a process that can be used not only during the Residency Match process, but also throughout graduate medical education and future career decisions.

Seeing Yourself Through the Learner's Eyes: Incorporating Smart Glasses Into Objective Structured Teaching Exercises for Faculty Development.

INTRODUCTION: Although physicians gain clinical knowledge in their specialty, it does not mean they receive adequate instruction to teach and provide feedback. Using smart glasses (SG) to provide educators with a first-person learner perspective has not been explored in faculty development such as Objective Structured Teaching Exercises (OSTEs). METHODS: Integrated within a 6-session continuing medical education-bearing certificate course, this descriptive study involved one session where participants provided feedback to a standardized student in an OSTE. Participants were recorded by mounted wall cameras (MWCs) and SG. They received verbal feedback on their performance based on a self-designed assessment tool. Participants reviewed the recorded content and identified areas for improvement, completed a survey about their experience with SG, and wrote a narrative reflection. RESULTS: Seventeen physicians at the assistant professor level participated in the session; data were analyzed on the 14 who had both MWC and SG recordings and who also completed the survey and reflection. All were comfortable with the standardized student wearing SG and indicated it did not affect communication. Eighty-five percent of the participants felt the SG provided additional feedback not available with the MWC, with majority noting additional feedback was related to eye contact, body language, voice inflection, and tone. Eighty-six percent see value in using SG for faculty development, and 79% felt that periodically using SG in their teaching would improve quality. CONCLUSION: Use of SG during an OSTE on giving feedback was a nondistracting and positive experience. SG provided affective feedback otherwise not perceived from a standard MWC.

Effects of Transcendental Meditation on Academic Physician Burnout and Depression: A Mixed Methods Randomized Controlled Trial.

INTRODUCTION: Burnout is pervasive among physicians and has widespread implications for individuals and institutions. This research study examines, for the first time, the effects of the Transcendental Meditation (TM) technique on academic physician burnout and depression. METHODS: A mixed methods randomized controlled trial was conducted with 40 academic physicians representing 15 specialties at a medical school and affiliated VA hospital using the TM technique as the active intervention. Physicians were measured at baseline, 1 month, and 4 months using the Maslach Burnout Inventory, Beck Depression Inventory, Insomnia Severity Index, Perceived Stress Scale, and Brief Resilience Scale. Repeated measures analysis of covariance was used to assess adjusted mean change scores for the 1- and 4-months posttests. Qualitative interviews were conducted at baseline and 4 months and compared with the quantitative measurements. RESULTS: Significant improvements were found for the TM group compared with controls at 4 months in total burnout ( p = .020) including the Maslach Burnout Inventory dimensions of emotional exhaustion ( p = .042) and personal accomplishment ( p = .018) and depression ( p = .016). Qualitative interviews supported quantitative outcomes. Physicians reported classic burnout and depression symptoms in baseline interviews. Those regularly practicing the TM technique reported relief from those symptoms. The control group did not state similar changes. DISCUSSION: Mixed methods findings suggest the TM technique is a viable and effective intervention to decrease burnout and depression for academic physicians. Larger longitudinal studies with a wider range of health care providers are needed to validate these findings for extrapolation to the greater medical community.

Are online student evaluations of faculty influenced by the timing of evaluations?

Student evaluations of faculty are important components of the medical curriculum and faculty development. To improve the effectiveness and timeliness of student evaluations of faculty in the physiology course, we investigated whether evaluations submitted during the course differed from those submitted after completion of the course. A secure web-based system was developed to collect student evaluations that included numerical rankings (1-5) of faculty performance and a section for comments. The grades that students received in the course were added to the data, which were sorted according to the time of submission of the evaluations and analyzed by Pearson's correlation and Student's t-test. Only 26% of students elected to submit evaluations before completion of the course, and the average faculty ratings of these evaluations were highly correlated [r(14) = 0.91] with the evaluations submitted after completion of the course. Faculty evaluations were also significantly correlated with the previous year [r(14) = 0.88]. Concurrent evaluators provided more comments that were statistically longer and subjectively scored as more "substantive." Students who submitted their evaluations during the course and who included comments had significantly higher final grades in the course. In conclusion, the numeric ratings that faculty received were not influenced by the timing of student evaluations. However, students who submitted early evaluations tended to be more engaged as evidenced by their more substantive comments and their better performance on exams. The consistency of faculty evaluations from year to year and concurrent versus at the end of the course suggest that faculty tend not to make significant adjustments to student evaluations.

An analysis of lecture video utilization in undergraduate medical education: associations with performance in the courses.

BACKGROUND: Increasing numbers of medical schools are providing videos of lectures to their students. This study sought to analyze utilization of lecture videos by medical students in their basic science courses and to determine if student utilization was associated with performance on exams. METHODS: Streaming videos of lectures (n = 149) to first year and second year medical students (n = 284) were made available through a password-protected server. Server logs were analyzed over a 10-week period for both classes. For each lecture, the logs recorded time and location from which students accessed the file. A survey was administered at the end of the courses to obtain additional information about student use of the videos. RESULTS: There was a wide disparity in the level of use of lecture videos by medical students with the majority of students accessing the lecture videos sparingly (60% of the students viewed less than 10% of the available videos. The anonymous student survey revealed that students tended to view the videos by themselves from home during weekends and prior to exams. Students who accessed lecture videos more frequently had significantly (p < 0.002) lower exam scores. CONCLUSION: We conclude that videos of lectures are used by relatively few medical students and that individual use of videos is associated with the degree to which students are having difficulty with the subject matter.

Neuromyelitis optica (NMO) antibody positivity in patients with transverse myelitis and no visual manifestations.

BACKGROUND AND PURPOSE: To describe a subgroup of patients with IgG antibody to Aquaporin 4 Protein (AQP4) specific to neuromyelitis optica (NMO), who did not have clinical manifestations of optic nerve involvement at the time of diagnosis. METHODS: Assessment of five patients (four African Americans and one Latino) with myelitis, who were NMO IgG antibody positive, who had no detected optic nerve involvement, over a span of one to eighteen years. RESULTS: Cerebrospinal fluid (CSF) studies showed lymphocytic pleocytosis, elevated interleukin (IL6), oligoclonal bands (OCB), myelin basic protein (MBP), and elevated albumin and IgG index. Serology showed an association with antinuclear antibody (ANA) positivity and antithyroid peroxidase (TPO) antibody. Our patients responded well to acute treatment with intravenous corticosteroids and long-term treatment with oral prednisone and azathioprine. CONCLUSIONS: The aquaporin protein autoimmune disease previously identified as neuromyelitis optica (NMO) may more correctly be identified as neuromyelitis (NM), and future diagnostic criteria should take into account the population of patients with antibody to aquaporin 4 protein, without clinically evident optic nerve pathology. Future research may indicate that the entity of NMO is a subcategory of the NM population.

Simulation-Based Mastery Learning Improves Medical Student Performance and Retention of Core Clinical Skills.

INTRODUCTION: Simulation-based mastery learning (SBML) improves procedural skills among medical trainees. We employed an SBML method that includes an asynchronous knowledge acquisition portion and a hands-on skill acquisition portion with simulation to assess senior medical student performance and retention of the following 6 core clinical skills: (a) ultrasound-guided peripheral intravenous placement, (b) basic skin laceration repair, (c) chest compressions, (d) bag-valve mask ventilation, (e) defibrillator management, and (f) code leadership. METHODS: Seven emergency medicine (EM) faculty members developed curricula, created checklists, and set minimum passing standards (MPSs) to test mastery of the 6 skills. One hundred thirty-five students on an EM clerkship were pretested on all 6 skills, viewed online videos asynchronously followed by a multiple choice computer-based skill-related quiz, received one-on-one hands-on skill training using deliberate practice with feedback, and were posttested until MPS was met. We compared pretest and posttest performance. We also retested, unannounced, a convenience sample (36%) of students from 1 to 9 months postintervention to assess skill retention. RESULTS: All students passed each quiz. The percentage of students who reached each MPS increased significantly (P < 0.001) from pretest to posttest for all 6 clinical skills. Ninety-eight percent of the students scored at or above the MPS when retested 1 to 9 months later. There was no significant decrease in mean score for any of the 6 skills between posttest and retention testing. CONCLUSIONS: Simulation-based mastery learning using a substantial asynchronous component is an effective way for senior medical students to learn and retain EM clinical skills. This method can be adapted to other skill training necessary for residency readiness.

Multifocal motor neuropathy: pathologic alterations at the site of conduction block.

The pathologic changes of nerves in multifocal motor neuropathy (MMN), a rare neuropathy with selective focal conduction block of motor fibers in mixed nerves, remain essentially unstudied. Fascicular nerve biopsy of 8 forearm or arm nerves in 7 patients with typical MMN was undertaken for diagnostic reasons at the site of the conduction block. Abnormalities were seen in 7 of 8 nerves, including a varying degree of multifocal fiber degeneration and loss, an altered fiber size distribution with fewer large fibers, an increased frequency of remyelinated fiber profiles, and frequent and prominent regenerating fiber clusters. Small epineurial perivascular inflammatory infiltrates were observed in 2 nerves. We did not observe overt segmental demyelination or onion bulb formation. We hypothesize that an antibody-mediated attack directed against components of axolemma at nodes of Ranvier could cause conduction block, transitory paranodal demyelination and remyelination, and axonal degeneration and regeneration. Alternatively, the antibody attack could be directed at components of paranodal myelin. We favor the first hypothesis because in nerves studied by us, axonal pathological alteration predominated over myelin pathology. Irrespective of which mechanism is involved, we conclude that the unequivocal multifocal fiber degeneration and loss and regenerative clusters at sites of conduction block explains the observed clinical muscle weakness and atrophy and alterations of motor unit potentials. The occurrence of conduction block and multifocal fiber degeneration and regeneration at the same sites suggests that the processes of conduction block and fiber degeneration and regeneration are linked. Finding discrete multifocal fiber degeneration may also provide an explanation for why the functional abnormalities remain unchanged over long periods of time at discrete proximal to distal levels of nerve and may emphasize a need for early intervention (assuming that efficacious treatment is available).

Treatment of headache with botulinum toxin administration.

Botulinum toxin has been increasingly applied to the treatment of a wide variety of neurological disorders. Its application to headache disorders, and specifically those classified as migraine or tension-type, followed the observation of its effectiveness in decreasing pain. Studies that have primarily used botulinum toxin type A, but with varying dose regimens and sites of administration, have since observed its beneficial effects and in those subjects, headaches have lessened in their frequency or severity. However, questions that have primarily concerned dose and sites of administration have since arisen and clear guidelines for botulinum toxin use in headache disorders have yet to be developed.

Paget's disease of bone.

Paget's disease is an osteoclastic-mediated disorder of bone that results in abnormal bone resorption associated with inadequate remodeling that leads to mechanically weakened bone. Demonstrating variable geographic prevalence, it is becoming less frequent and age of onset is lengthening in areas of once high prevalence prior to the institution of effective medical therapies, suggesting its etiology involves both environmental as well as genetic factors. Insights into its pathophysiology are helping to clarify other inherited osteolytic disorders of bone by providing additional insights into related cellular processes.

Neurologic aspects of lymphoma and leukemias.

The lymphomas and leukemias are a heterogenous group of hematologic malignancies with protean manifestations. Neurologic sequelae of the diseases have been recognized since the time the conditions were first described in the mid-1800s. Although our understanding of the various presentations of these blood disorders evolved along with our knowledge of malignancies, accurate diagnosis can still be difficult. It is critical for neurologists to have a high index of clinical suspicion to appropriately recognize their heralding features. This review's focus is the relevant clinical neurologic features and diagnostic studies that identify leukemias and lymphomas affecting the nervous system.

Neurologic aspects of lymphoma and leukemias.

The leukemias and lymphomas represent a heterogenous group of hematologic malignancies with protean manifestations. Neurologic sequelae of the diseases have been recognized almost since the time the conditions were first described in the mid-1800s. Although our understanding of the various presentations of these blood disorders has evolved along with our knowledge of the malignancies, accurate diagnosis can still be difficult. It is critical for neurologists to have a high index of clinical suspicion to appropriately recognize the heralding features. This review focuses on the relevant clinical neurologic features and diagnostic studies to identify leukemias and lymphomas affecting the nervous system.

Management of critical illness polyneuropathy and myopathy.

A syndrome of generalized weakness, areflexia, and difficulty with weaning from a ventilator is a common clinical presentation in the critically ill patient, especially in the setting of sepsis, multiorgan failure, and hyperglycemia. At first believed to be a manifestation of nerve (critical illness neuropathy, CIN) or muscle (critical illness myopathy, CIM) dysfunction, our current conceptualization is as a spectrum (critical illness neuromuscular abnormalities, CINMA) that varies in extent and site(s) of involvement, but often a similar clinical presentation. Signs and symptoms of CINMA must be identified early to foster recovery and limit morbidity and mortality. The medical history is crucial in excluding preexisting neuromuscular conditions and electrodiagnostic testing helps to establish the diagnosis and prognostication. A stepwise approach to the management of a patient with CINMA is outlined, but avoiding potential medications, and ensuring supportive care are the primary interventions to consider. Recently intensive insulin therapy for hyperglycemia has been shown to lower the risk of CINMA and decrease the time of ventilatory support, but with a greater risk of hypoglycemia. Future therapeutic interventions will require a better understanding of disease pathogenesis, but may target proinflammatory cytokine and free-radical pathways, muscle gene expression, ion channel function, or proteolytic muscle protein mechanisms. Rehabilitation is an equally essential component in a patient's management. Although prognosis depends on the extent of the underlying muscle and nerve damage, mild persistent deficits are common and severe disability may be persistent.

An audience response system may influence student performance on anatomy examination questions.

This study integrated an in-house audience response system (ARS) in the human anatomy course over two years to determine whether students performed better on high-stakes examinations following exposure to similar interactive questions in a large lecture format. Questions in an interactive ARS format were presented in lectures via PowerPoint presentations. Students who chose to participate in the anonymous ARS sessions submitted answers via their personal wireless devices (e.g., laptops, smartphones, PDAs, etc). Students were surveyed for feedback. Student participation in ARS activities was greatest (65-80%) in the first lecture. The number of students who actively participated in ARS activities decreased over the next four sessions, and then slightly increased in the last two sessions. This trend was the same for both years. Use of the ARS did not dramatically enhance overall student performance on examination questions that dealt with content similar to content presented in the ARS sessions. However, students who scored in the lower quartile of the examination performed better on the examination questions after the ARS was implemented. Accordingly, our findings suggest that the effect of ARS to improve student performance on examinations was not uniform. The overall benefit of an ARS to enhance the lecture experience was confirmed by student surveys.
