RESUMEN

Introduction: During the COVID-19 pandemic, care shifted from exclusively telemedicine to hybrid models with in-person, video, and telephone visits. We explored how patient satisfaction and visit preferences have changed by comparing in-person versus virtual visits (telephone and video) in an ambulatory neurology practice across three time points. Methods: Patients who completed a virtual visit in March 2020 (early-pandemic), May 2020 (mid-pandemic), and March 2021 (later-pandemic) were contacted. Patients were assessed for visit satisfaction and desire for future telemedicine. Univariate and multivariable logistic regression analysis was conducted to determine factors independently associated with video visit completion. Results: Four thousand seven hundred seventy-eight the number of ambulatory visits (n = 4,778) were performed (1,004 early; 1,265 mid; and 2,509 later); 1,724 patients (36%) assented to postvisit feedback; mean age 45.8 ± 24.4 years, 58% female, 79% white, and 56% with Medicare/Medicaid insurance. Patient satisfaction significantly increased (73% early, 79% mid, 81% later-pandemic, p = 0.008). Interest in telemedicine also increased for patients completing telephone visits (40% early, 50% mid, 59% later, p = 0.027) and video visits (52% early, 59% mid, 62% later, p = 0.035). Patients satisfied with telemedicine visits were younger (p < 0.001). White patients were more interested in future telemedicine (p = 0.037). Multivariable analysis showed that older patients (for each 1 year older), Black patients, and patients with Medicare/Medicaid were 2%, 45%, and 54% less likely to complete a video visit than telephone, respectively. Discussion: Patients, especially younger ones, have become more satisfied and more interested in hybrid care models during the COVID-19 pandemic. Barriers to conducting video visits persist for older, Black patients with Medicare or Medicaid insurance.

RESUMEN

The surgical treatment of insular gliomas requires specialized knowledge. Over the last three decades, increased momentum in surgical resection of insular gliomas shifted the focus from one of expectant management to maximal safe resection to establish a diagnosis, characterize tumor genetics, treat preoperative symptoms (i.e., seizures), and delay malignant transformation through tumor cytoreduction. A comprehensive review of the literature was performed regarding insular glioma classification/genetics, insular anatomy, surgical approaches, and patient outcomes. Modern large, published series of insular resections have reported a median 80% resection, 80% improvement in preoperative seizures, and postsurgical permanent neurologic deficits of less than 10%. Major complication avoidance includes recognition and preservation of eloquent cortex for language and respecting the lateral lenticulostriate arteries.

RESUMEN

PHENOMENON: Opioid use disorder (OUD) is a growing public health crisis. Many residents and physicians do not feel comfortable working with patients with OUD. Social stigma promotes negative attitudes toward these patients and is a roadblock to delivering equitable and effective care. This study sought to (1) characterize medical students' experiences with patients with OUD, (2) understand the features that make a patient encounter memorable, (3) explore factors that influence future practice, and (4) describe the influence on stigma toward patients with OUD. Approach: A study was conducted using qualitative descriptive theory and purposive sampling of fourth-year medical students (M4s) enrolled at Wake Forest School of Medicine (WFSOM). Data collection consisted of a free-text question as a part of a larger survey to M4s in the Class of 2019 and 2020, followed by semi-structured interviews. The goal of the survey was to gain a broad understanding of student encounters with patients with OUD. The goal of the interviews was to gain a deeper understanding of the impact of these encounters on future practice and stigma. Thematic analysis was used to analyze all data. Findings: One-hundred-seventy out of 237 students (RR = 71.7%) completed the free text question describing a memorable encounter with a patient with OUD. Twelve students then completed interviews. Patient encounters occurred in three primary settings: Emergency department, inpatient clerkship, or Intensive Outpatient Program (IOP) meetings during psychiatry clerkship. Clinical encounters were memorable when there was: (1) conflict with patients or teams, (2) complicated care, (3) inadequate care, and (4) relevance to the student's future career. Memorable encounters influenced future practice by changing students' approaches to: (1) future treatment, (2) future communication, or (3) allowing students to practice professionalism. Regarding opioid stigma, students reported that these encounters made them: (1) more aware of stereotypes in medicine, (2) stereotypes in their personal lives, and (3) generated actions that students want to take in the future. Insights: A single, influential clinical encounter has the potential to substantially influence medical students' approach to patients with OUD, including both clinical management and attitudes toward care. Affecting encounters increased knowledge of OUD and fostered empathy and perspective-taking. Not all encounters had a defining impact on students' stigma toward OUD. Medical schools need to create opportunities that will have lasting impact by encouraging students to fully engage with patients with OUD.Supplemental data for this article is available online at https://doi.org/10.1080/10401334.2022.2038175 .

RESUMEN

Background: With a drastic shortage of addiction medicine specialists-and an ever-growing number of patients with opioid use disorder (OUD)-there is a dire need for more clinicians to feel confident in prevention and management of OUD and obtain a DEA-X waiver to prescribe medications to treat OUD. Here we determine if it is feasible to certify 4th year medical students with DEA-X waiver training as a component of the PROUD (Prevent and Reduce Opioid Use Disorder) curriculum, and if PROUD enhanced preparedness for medical students to manage OUD as interns. Methods: We implemented a sequential mixed-methods IRB approved study to assess feasibility (completing all required components of DEA-X waiver training) and impact of PROUD (measured by knowledge growth, enhancement for residency, and utilization of training during internship). Students completed 11 hours of required OUD training. Quantitative data included pre-/post- knowledge and curriculum satisfaction assessments as well as long-term impact with follow up survey as interns. Qualitative data was collected by survey and semi-structured focus groups. Results: All 120 graduating medical students completed the required components of the curriculum. Knowledge improved on the Provider Clinical Support Services (12.9-17.3, p < 0.0001) and Brief Opioid Overdose Knowledge assessments (10.15-10.81, p < 0.0001). Course satisfaction was high: 90% recommended online modules; 85% recommended training overall. Six qualitative themes emerged: (1) curriculum content was practical, (2) online modules allowed flexibility, (3) in-person seminars ensured authenticity, (4) timing at the transition to residency was optimal, (5) curriculum enhanced awareness and confidence, and (6) training was applicable to future careers. At 3 months, 60% reported using their training during internship; 64% felt more prepared to treat OUD than peers. Conclusions: PROUD trained 4th year medical students in opioid stewardship. As interns, students felt ready to serve as change agents to prevent, diagnose, and treat OUD.

RESUMEN

BACKGROUND: Our study aim was to evaluate neuromuscular ultrasound (NMUS) for the assessment of taxane chemotherapy-induced peripheral neuropathy (CIPN), the dose-limiting toxicity of this agent. METHODS: This cross-sectional study of breast cancer patients with taxane CIPN measured nerve cross-sectional area (CSA) by NMUS and compared with healthy historical controls. Correlations were determined between CSA and symptom scale, nerve conduction studies, and intraepidermal nerve fiber density (IENFD). RESULTS: A total of 20 participants reported moderate CIPN symptoms at a median of 3.8 months following the last taxane dose. Sural nerve CSA was 1.2 mm2 smaller than healthy controls (P ≤ .01). Older age and time since taxane were associated with smaller sural nerve CSA. For each 1 mm2 decrease in sural nerve CSA, distal IENFD decreased by 2.1 nerve/mm (R2 0.30; P = .04). CONCLUSIONS: These data support a sensory predominant taxane neuropathy or neuronopathy and warrant future research on longitudinal NMUS assessment of CIPN.

RESUMEN

OPINION STATEMENT: Though the majority of nervous system tumors are sporadic, several clinically relevant genetic syndromes are associated with a predisposition to tumors of the central and peripheral nervous system including neurofibromatosis type 1 (NF1), type 2 (NF2), and schwannomatosis (SWN). These represent prototypical tumor suppressor syndromes where loss of a tumor suppressor gene-protein impairs the cell's ability to regulate cell proliferation. While clinical manifestations vary widely for each of these syndromes, tumors arising in the peripheral nerve sheath are a unifying feature. Clinical clues should prompt the clinician to recognize the underlying genetic syndrome and screen for associated tumors including, among others, plexiform neurofibromas and gliomas in NF1 and vestibular schwannomas, meningiomas, and spinal ependymomas in NF2. Improvements in mechanistic understanding of how the genetic mutations that underlie these syndromes contribute to tumor formation have led to new advances in targeted therapies. MEK inhibitors have shown promise for treating progressive plexiform neurofibromas in NF1. Bevacizumab has been shown to improve hearing and treat vestibular schwannomas in NF2. This article reviews the currently available data on management of tumors associated with these three syndromes.

RESUMEN

PURPOSE: Clinical factors and neuro-imaging in patients with glioblastoma who appear to progress following standard chemoradiation are unable to reliably distinguish tumor progression from pseudo-progression. As a result, surgery is commonly recommended to establish a final diagnosis. However, studies evaluating the pathologists' agreement on pathologic diagnoses in this setting have not been previously evaluated. METHODS: A hypothetical clinical history coupled with images of histological sections from 13 patients with glioblastoma who underwent diagnostic surgery for suspected early recurrence were sent to 101 pathologists from 50 NCI-designated Cancer Centers. Pathologists were asked to provide a final diagnosis (active tumor, treatment effect, or unable to classify) and to report on percent active tumor, treatment effect, and degree of cellularity and degree of mitotic activity. RESULTS: Forty-eight pathologists (48%) from 30 centers responded. In three cases > 75% of pathologists diagnosed active tumor. In two cases > 75% diagnosed treatment effect. However, in the remaining eight cases the disparity in diagnoses was striking (maximum agreement on final diagnosis ranged from 36 to 68%). Overall, only marginal agreement was observed in the overall assessment of disease status [kappa score 0.228 (95% CI 0.22-0.24)]. CONCLUSIONS: Confidence in any clinical diagnostic assay requires that very similar results are obtained from identical specimens evaluated by sophisticated clinicians and institutions. The findings of this study illustrate that the diagnostic agreement between different cases of repeat resection for suspected recurrent glioblastoma can be variable. This raises concerns as pathological diagnoses are critical in directing standard and experimental care in this setting.

RESUMEN

OBJECTIVES: Ketogenic diets (KDs) have long been used to treat epilepsy and are being explored in a variety of diseases. Preclinical data suggest KDs affect inflammation and cytokine release. It is unknown whether KDs affect white blood cell (WBC) counts over time. This is particularly important in clinical populations who may be immune-suppressed at baseline, such as those with cancer or autoimmune disorders. METHODS: A retrospective review of 125 consecutive adults seen at the Adult Epilepsy Diet Center (AEDC) was conducted. Clinical data regarding compliance, laboratory data, weights, and diet records were collected. A control cohort consisted of patients evaluated at the AEDC who elected not to complete a prescribed KD. RESULTS: In 52 adults on KDs, there was a small but statistically significant decrease in WBC and absolute neutrophil counts at 6 and 12 months into KD therapy. There was no effect on lymphocyte counts. This pattern was also seen in a small population of patients with gliomas (n = 10) on KDs, most (n = 8) of whom had also received chemotherapy and radiation, putting them at risk for bone marrow suppression. Across both glioma and non-glioma groups, patients with pre-existing lymphopenia did not have further worsening of their counts on the KD. CONCLUSIONS: In this retrospective case-control study, a small but significant decrease in total WBC and neutrophil counts was observed in patients with epilepsy treated with the KDs. These patterns are similar in patients with and without gliomas suggesting baseline immunosuppression does not worsen with KD. These findings provide data for prospective confirmatory studies.

RESUMEN

PURPOSE: For glioblastoma (GBM), imaging response (IR) or pseudoprogression (PSP) is frequently observed after chemoradiation and may connote a favorable prognosis. With tumors categorized by the Cancer Genome Atlas Project (mesenchymal, classical, neural, and proneural) and by methylguanine-methyltransferase (MGMT) methylation status, we attempted to determine if certain genomic or molecular subtypes of GBM were specifically associated with IR or PSP. METHODS: Patients with GBM treated at two institutions were reviewed. Kaplan-Meier method was used to estimate overall survival (OS) and progression-free survival (PFS). Mantel-cox test determined effect of IR and PSP on OS and PFS. Fisher's exact test was utilized to correlate IR and PSP with genomic subtypes and MGMT status. RESULTS: Eighty-two patients with GBM were reviewed. The median OS and PFS were 17.9 months and 8.9 months. IR was observed in 28 (40%) and was associated with improved OS (median 29.4 vs 14.5 months p < 0.01) and PFS (median 17.7 vs 5.5 months, p < 0.01). PSP was observed in 14 (19.2%) and trended towards improved PFS (15.0 vs 7.7 months p = 0.08). Tumors with a proneural component had a higher rate of IR compared to those without a proneural component (IR 60% vs 28%; p = 0.03). MGMT methylation was associated with IR (58% vs 24%, p = 0.032), but not PSP (34%, p = 0.10). CONCLUSION: IR is associated with improved OS and PFS. The proneural subtype and MGMT methylated tumors had higher rates of IR.

RESUMEN

OPINION STATEMENT: Advances in technology are revolutionizing medicine and the limits of what we can offer to our patients. In neurosurgery, technology continues to reduce morbidity, increase surgical accuracy, facilitate tissue acquisition, and promote novel techniques for prolonging survival in patients with neuro-oncologic disease. Surgery has been the backbone of glioma diagnosis and treatment by providing adequate, high quality material for precise histologic diagnosis, and genomic characterization in the setting of significant intratumoral heterogeneity, thus allowing personalized treatment selection in the clinic. The ability to obtain and accurately measure the maximal extent of resection in glioma surgery also remains a central role of the neurosurgeon in managing this cancer. To meet these goals, today's operating room has transformed from the traditional operating table and anesthesia machine to include neuronavigation instrumentation, intraoperative computed tomography, and magnetic resonance imaging scanners, advanced surgical microscopes fitted with fluorescent light filters, and electrocorticography machines. While surgeons, oncologists, and radiation oncologists all play unique critical roles in the care of patients with malignant gliomas, familiarity with developing techniques in complimentary subspecialties can enhance coordination of patient care, research productivity, professional interactions, and patient confidence and comfort with the physician team. Herein, we provide a summary of the advances in the field of neurosurgical oncology which allow more precise and optimal surgical resection for patients with malignant gliomas.

RESUMEN

Although optic pathway gliomas are the most common brain tumors associated with neurofibromatosis type 1 (NF1), extra-optic gliomas occur and may behave more aggressively with outcomes that differ by age. A retrospective case-control study was designed to describe the clinical course of adult NF1 patients with progressive extra-optic pilocytic astrocytomas (PAs) and compare to a pediatric cohort. Data for patients treated at the Johns Hopkins Comprehensive Neurofibromatosis Center from 2003 to 2013 were reviewed to identify cases (adults, age >18) and controls (pediatric, age <18) with clinically or radiographically progressive extra-optic PAs. Demographic, clinical, histologic, and radiographic data were collected. Three adult NF1 cases and four pediatric NF1 controls were identified. Mean age was 32.3 ± 9.5 years, 66% male (cases); 12.8 ± 4.2 years, 100% male (controls). Symptomatic progression occurred in two-of-three adults (67%) while the majority of pediatric patients presented with isolated radiographic progression (n = 3, 75%). Onset tended to be more rapid in adults (4 ± 1 vs. 14 ± 8.3 months, P = 0.10). Subtotal resection was the treatment for all pediatric patients. Radiotherapy (n = 2), chemotherapy (n = 2), and targeted, biologic agents (n = 2) were administered in adults. Although all pediatric patients are living, outcomes were universally poor in adults with progression to death in all (median survival 17.1 months, range 6.6-30.3). In conclusion, despite grade I histology, all three adult NF1 patients with progressive extra-optic PAs suffered an aggressive clinical course which was not seen in pediatric patients. Clinicians should be aware of this clinico-histologic discrepancy when counseling and managing adult NF1 patients with progressive extra-optic PAs. © 2016 Wiley Periodicals, Inc.

RESUMEN

Adding temozolomide (TMZ) to radiation for patients with newly-diagnosed anaplastic astrocytomas (AAs) is common clinical practice despite the lack of prospective studies demonstrating a survival advantage. Two retrospective studies, each with methodologic limitations, provide conflicting advice regarding treatment. This single-institution retrospective study was conducted to determine survival trends in patients with AA. All patients ≥18 years with newly-diagnosed AA treated at Johns Hopkins from 1995 to 2012 were included. As we incorporated TMZ into high-grade glioma treatment regimens in 2004, patients were divided into pre-2004 and post-2004 groups for analysis. Clinical, radiographic, and pathologic data were collected. Median overall survival (OS) was calculated using Kaplan-Meier estimates. A total of 196 patients were identified; 74 pre-2004 and 122 post-2004; mean age 47 ± 15 years; 57 % male; 87 % white, 69 % surgical debulking. Mean RT dose 5676 + 746 cGy; duration of concurrent chemoradiation 5.8 ± 0.8 weeks; and mean adjuvant chemotherapy 4.3 + 2.8 cycles. Baseline prognostic factors did not differ between groups. Chemotherapy was administered to 12 % of patients pre-2004 (TMZ = 1, procarbazine, lomustine and vincristine = 2, carmustine wafer = 6) and 94 % post-2004 (TMZ in all, p < 0.001). Median OS was 32 months (95 % CI 23-43). Survival was longer in the post-2004 cohort (37 mo, 24-64) than pre-2004 (27 mo, 19-40; HR 0.75, 0.53-1.06, p = 0.11). Multivariate analysis controlling for age, Karnofsky performance status, and extent of resection revealed a 36 % reduced risk of death (HR 0.64, 0.44-0.91, p = 0.015) in patients treated post-2004. This retrospective review found survival in newly diagnosed patients with AA improved with the addition of temozolomide to standard radiation. Until prospective randomized phase III data are available, these data support the practice of incorporating TMZ in the management of newly-diagnosed AA.

RESUMEN

OPINION STATEMENT: Central nervous system gliomas are the most common primary brain tumor, and these are most often high-grade gliomas. Standard therapy includes a combination of surgery, radiation, and chemotherapy which provides a modest increase in survival, but virtually, no patients are cured, the overall prognosis remains poor, and new therapies are desperately needed. Tumor metabolism is a well-recognized but understudied therapeutic approach to treating cancers. Dietary and nondietary modulation of glucose homeostasis and the incorporation of dietary supplements and other natural substances are potentially important interventions to affect cancer cell growth, palliate symptoms, reduce treatment-associated side effects, and improve the quality and quantity of life in patients with cancer. These approaches are highly desired by patients. However, they can be financially burdensome, associated with toxicities, and have, on occasion, reduced the efficacy of proven therapies and negatively impacted patient outcomes. The lack of rigorous scientific data evaluating almost all diet and supplement-based therapies currently limits their incorporation into standard oncologic practice. Rigorous studies are needed to document and improve these potentially useful approaches in patients with brain and other malignancies.

RESUMEN

Gliomas classified as grade II by the World Health Organization (WHO) include astrocytomas, oligodendrogliomas, and mixed oligoastrocytomas. This heterogeneous group of conditions is associated with a more favorable prognosis and longer-term survival than high-grade gliomas (HGGs). Neurosurgical resection and radiation therapy improve survival in symptomatic, progressive, or high-risk grade II gliomas. Until recently, the role of chemotherapy has been less clear. This review draws on insights from the management of HGGs and emerging data on the addition of PCV (procarbazine, lomustine [CCNU], and vincristine) to radiation for these neoplasms. Specifically, this review focuses on the current status of chemotherapeutic management of grade II gliomas, including optimal timing of treatment, and management of 1p19q codeleted and non-codeleted tumors.

RESUMEN

BACKGROUND: Peer review is essential to the advancement of knowledge. However, training on how to conduct peer review is limited, unorganized, and not well studied. Thus, we sought to determine if a structured mentored peer-review program improved peer review training as measured by multiple quantitative and qualitative assessments. METHODS: This pre-post intervention study enrolled 55 mentees across 5 cohorts from 2020 to 2023. Each cohort completed pre-program evaluations, participated in 2 mentored reviews, and completed post-program evaluations over 6 months. Mentors and mentees completed pre-program demographic and review experience questionnaires. Outcome measures included (1) total and sub-scores on the modified Review Quality Index (mRQI) applied to the same pre-selected research manuscript reviewed by mentees both pre and post intervention, (2) mentee self-perceived comfort with and understanding of the review process using a custom questionnaire, and (3) mentor satisfaction surveys. Pre- and post-program measures were compared using the Wilcoxon signed-rank test. RESULTS: Post-program total modified RQI score (median (IQR) = 31 (26.3-35.8)) was higher than pre-program total score (26.6 (19.7-29.7)) for the 42 mentees who completed both pre- and post-program reviews. Mentees reported improved perception of review (median (IQR) pre = 4 (3-4), post = 5 (4-5)) and editorial processes (pre = 3 (2-4), post = 4 (4-5)) as well as self-perceived confidence in completing an independent review of both scientific (median (IQR) pre = 2 (2-3), post = 4 (4-4)) and non-scientific (pre = 3 (2-4), post = 4 (4-5)) manuscripts following program participation. p < 0.0001 for all scores noted. Mentors reported high scores for enjoyment (median (range) 5/5 (3-5)) and interest in repeat participation (5/5 (2-5)). CONCLUSIONS: A 6-month structured mentored-review program including 2 mentored reviews improves peer review training as measured by the modified RQI as well as participant self-perceived understanding of publication science with high mentor satisfaction.

RESUMEN

Chemotherapy-induced peripheral neuropathy (CIPN) is a debilitating sequela that is difficult for both clinicians and cancer patients to manage. Precise mechanisms of CIPN remain elusive and current clinically prescribed therapies for CIPN have limited efficacy. Recent studies have begun investigating the interactions between the peripheral and central nervous systems and the immune system. Understanding these neuroimmune interactions may shift the paradigm of elucidating CIPN mechanisms. Although the contribution of immune cells to CIPN pathogenesis represents a promising area of research, its fully defined mechanisms have not yet been established. Therefore, in this review, we will discuss (i) current shortcoming of CIPN treatments, (ii) the roles of neuroimmune interactions in CIPN development and (iii) potential neuroimmune interaction-targeting treatment strategies for CIPN. Interestingly, monocytes/macrophages in dorsal root ganglia; microglia and astrocytes in spinal cord; mast cells in skin; and Schwann cell near peripheral nerves have been identified as inducers of CIPN behaviors, whereas T cells have been found to contribute to CIPN resolution. Additionally, nerve-resident immune cells have been targeted as prevention and/or therapy for CIPN using traditional herbal medicines, small molecule inhibitors, and intravenous immunoglobulins in a preclinical setting. Overall, unveiling neuroimmune interactions associated with CIPN may ultimately reduce cancer mortality and improve cancer patients' quality of life.

RESUMEN

Introduction: Persistent Tic Disorders such as Tourette Syndrome are common neurodevelopmental disorders that are highly stigmatized. Many individuals with Persistent Tic Disorders experience peer rejection, loneliness, and self-stigma. Experiencing stigmatization during childhood can influence the persistence of moderate-to-severe tics later in life. Additionally, these factors have been associated with increased suicidal ideation, suicide attempts, and psychiatric symptom severity. There is a need for interventions to reduce stigma and stigmatization in Persistent Tic Disorders. Before developing cost-effective interventions to mitigate stigma's profound downstream health impacts, a reliable measure of stigmatization must be created. The overarching goal of this research is to develop and validate the Tourette Discrimination-Stigmatization (TD-STIGMA) Scale. Methods: This paper presents the study protocol for developing and validating the TD-STIGMA Scale. The study is designed as a mixed methods study to develop the TD-STIGMA scale and evaluate its psychometric properties. The study uses a phased approach: (1) collection of narrative and thematic content data through in-depth qualitative interviews of stakeholders, (2) development of a novel TD-STIGMA self-report scale using the Delphi Method based on these results, and (3) completion of analyses to determine the scale's psychometric properties (confirmatory factor analysis, convergent, known-group, criterion validity, and test-retest reliability). Discussion: This project will result in a personalized approach to stigma measurement about youth and young adults with Persistent Tic Disorders, which to date does not exist. There are several limitations. Comorbidities or spiritual or cultural beliefs may affect perceptions of stigma and are not directly assessed in this study. We will utilize institutional resources for community outreach to purposefully sample underrepresented minorities who may be at disproportionate risk of adverse outcomes. However, this may not be fully representative of the generalized tic population. The study team will be purposeful in maintaining participant engagement for study retention. Lastly, participants from a tertiary referral center may not fully represent the generalized tic community. However, we hope our broad recruitment strategy and virtual study visits will facilitate a diverse and inclusive sampling of the patient population.

RESUMEN

PURPOSE: Although fewer than 5% of high-grade gliomas (HGG) are BRAF-V600E mutated, these tumors are notable as BRAF-targeted therapy shows efficacy for some populations. The purpose of this study was to evaluate response to the combination of encorafenib with binimetinib in adults with recurrent BRAF-V600-mutated HGG. PATIENTS AND METHODS: In this phase 2, open-label, Adult Brain Tumor Consortium (ABTC) trial (NCT03973918), encorafenib and binimetinib were administered at their FDA-approved doses continuously in 28-day cycles. Eligible patients were required to have HGG or glioblastoma with a BRAF-V600E alteration that was recurrent following at least one line of therapy, including radiotherapy. RESULTS: Five patients enrolled between January 2020 and administrative termination in November 2021 (due to closure of the ABTC). Enrolled patients received treatment for 2 to 40 months; currently one patient remains on treatment. Centrally determined radiographic response rate was 60%, with one complete response and two partial responses. Methylation profiling revealed that all tumors cluster most closely with anaplastic pleomorphic xanthoastrocytoma (PXA). Transcriptional profile for MAPK-response signature was similar across all tumors at baseline and did not correlate with response in this small population. Circulating tumor DNA measured in plasma samples before treatment, during response, and upon progression showed feasibility of detection for the BRAF-V600E alteration. No new safety signal was detected. CONCLUSIONS: Encorafenib and binimetinib exhibit positive tumor responses in patients with recurrent BRAF-V600E mutant HGG in this small series, warranting therapeutic consideration. Although toxicity remains a concern for BRAF-targeted therapies, no new safety signal was observed in these patients.

RESUMEN

Neuromuscular ultrasound (NMUS) is a valuable tool in establishing a diagnosis of carpal tunnel syndrome (CTS) and can be particularly helpful in patients with clinical CTS but normal nerve conduction studies (NCSs). This case involves the uncommon presentation of enlarged median nerves on NMUS with normal NCS in a patient with breast cancer who developed chemotherapy-induced peripheral neuropathy and CTS after taxane treatment. This case demonstrates that CTS should not be excluded based on electrodiagnostic studies alone, and comorbid CTS should be considered in patients receiving neurotoxic chemotherapy, even in the setting of normal NCS.

RESUMEN

CONTEXT: Bedside clinical teaching is the backbone of clerkship education. Data-driven methods for supplementing bedside encounters with standardized content from vetted resources are needed. OBJECTIVE: To compare a flipped-classroom versus an interactive online-only instruction for improving knowledge, skills, self-directed learning (SDL) behaviors, and satisfaction in a medical school clerkship. METHODS: An IRB-approved prospective study employing a peer-reviewed clinical reasoning curriculum in neurology was conducted; 2nd-4th year medical students rotating through a required clerkship were enrolled. Students were randomized to flipped-classroom (i.e., flipped) or interactive asynchronous online instruction (i.e., online-only), which supplemented existing bedside teaching. Baseline and end-of-course knowledge, skill development, SDL behaviors, satisfaction, and long-term retention were assessed by peer-reviewed clinical reasoning exam, NBME scores, faculty/resident clinical evaluations, non-compulsory assignment completion, end-of-clerkship surveys, and objective structured clinical exam (OSCE). RESULTS: 104 students (49 flipped, 55 online-only) were enrolled. Age, gender, and training level did not differ by group (all p > 0.43); baseline knowledge was higher in the flipped group (p = 0.003). Knowledge-based exam scores did not differ by group even after adjusting for differences in baseline knowledge (2.3-points higher in flipped group, 95%CI -0.4-4.8, p = 0.07). Clinical skills were significantly higher in the flipped group, including examination skills (4.2 ± 0.5 vs. 3.9 ± 0.7, p = 0.03) and future housestaff potential (4.8 ± 0.3 vs 4.5 ± 0.6, p = 0.03). Students in the online-only group were more likely to engage in SDL (42 vs. 12%, p = 0.001) and reported more hours studying (6.1 vs. 3.8 hours, p = 0.03). Satisfaction (p = 0.51) and OSCE scores (p = 0.28) were not different by group. CONCLUSIONS: In this comparative study of two evidence-based curricular delivery approaches, we observed no difference in knowledge acquired. Greater clinical skills were observed with flipped instruction, while more SDL was observed with online-only instruction. Supplementing bedside teaching with blended instruction that balances live skill development with vetted online resources is optimal for clerkship education.
