BACKGROUND AND OBJECTIVES: The palliative impact of spine surgery for metastatic disease is evolving with improvements in surgical technique and multidisciplinary cancer care. The goal of this study was to prospectively evaluate long-term clinical outcomes including health-related quality-of-life (HRQOL) measures, using spine cancer–specific patient-reported-outcome (PRO) measures, in patients with symptomatic spinal metastases who underwent surgical management. METHODS: The Epidemiology, Process, and Outcomes of Spine Oncology (EPOSO, ClinicalTrials.gov identifier: NCT01825161) trial is a prospective-observational cohort study that included 10 specialist centers in North America and Europe. Patients aged 18 to 75 years who underwent surgery for spinal metastases were included. Prospective assessments included both spine tumor–specific and generic PRO tools which were collected for a minimum of 2 years post-treatment or until death. RESULTS: Two hundred and eighty patients (51.8% female, mean age 57.9 years) were included. At presentation, the mean Charlson Comorbidity Index was 6.0, 35.7% had neurological deficits as defined by the American Spinal Cord Injury Association scores, 47.2% had high-grade epidural spinal cord compression (2-3), and 89.6% had impending or frank instability as measured by a Spinal Instability Neoplastic Score of ≥7. The most common primary tumor sites were breast (20.2%), lung (18.8%), kidney (16.2%), and prostate (6.5%). The median overall survival postsurgery was 501 days, and the 2-year progression-free-survival rate was 38.4%. Compared with baseline, significant and durable improvements in HRQOL were observed at the 6-week, 12-week, 26-week, 1-year, and 2-year follow-up assessments from a battery of PRO questionnaires including the spine cancer–specific, validated, Spine Oncology Study Group Outcomes Questionnaire v2.0, the Short Form 36 version 2, EuroQol-5 Dimension (3L), and pain numerical rating scale score. CONCLUSION: Multi-institutional, prospective-outcomes data confirm that surgical decompression and/or stabilization provides meaningful and durable improvements in multiple HRQOL domains, including spine-specific outcomes based on the Spine Oncology Study Group Outcomes Questionnaire v2.0, for patients with metastatic spine disease.

BACKGROUND AND OBJECTIVES: Health care providers' exposure to global surgical disparities is limited in current nursing and/or medical school curricula. For instance, global health is often associated with infectious diseases or maternal health without acknowledging the growing need for surgical care in low- and middle-income countries (LMICs). We propose an international virtual hackathon based on neurosurgical patient cases in under-resourced settings as an educational tool to bring awareness to global surgical disparities and develop relationships among trainees in different countries. METHODS: Participants were recruited through email listservs, a social media campaign, and prize offerings. A 3-day virtual hackathon event was administered, which included workshops, mentorship, keynote panels, and pitch presentations to judges. Participants were presented with real patient cases and directed to solve a barrier to their care. Surveys assessed participants' backgrounds and event experience. The hackathon was executed through Zoom at Harvard Innovation Lab in Boston, MA, on March 25 to 27, 2022. Participants included medical students, with additional participants from business, engineering, or current health care workers. RESULTS: Three hundred seven applications were submitted for 100 spots. Participants included medical students, physicians, nurses, engineers, entrepreneurs, and undergraduates representing 25 countries and 82 cities. Fifty-one participants previously met a neurosurgeon, while 39 previously met a global health expert, with no difference between LMIC and high-income countries' respondents. Teams spent an average of 2.75 hours working with mentors, and 88% of postevent respondents said the event was “very” or “extremely conducive” to networking. Projects fell into 4 categories: access, language barriers, education and training, and resources. The winning team, which was interdisciplinary and international, developed an application that analyzes patient anatomy while performing physical therapy to facilitate remote care and clinical decision-making. CONCLUSION: An international virtual hackathon can be an educational tool to increase innovative ideas to address surgical disparities in LMICs and establish early collaborative relationships with medical trainees from different countries.

AbstractIntroduction/AimsMany people living with amyotrophic lateral sclerosis (PALS) report restrictions in their day‐to‐day communication (communicative participation). However, little is known about which speech features contribute to these restrictions. This study evaluated the effects of common speech symptoms in PALS (reduced overall speaking rate, slowed articulation rate, and increased pausing) on communicative participation restrictions.MethodsParticipants completed surveys (the Communicative Participation Item Bank‐short form; the self‐entry version of the ALS Functional Rating Scale‐Revised) and recorded themselves reading the Bamboo Passage aloud using a smartphone app. Rate and pause measures were extracted from the recordings. The association of various demographic, clinical, self‐reported, and acoustic speech features with communicative participation was evaluated with bivariate correlations. The contribution of salient rate and pause measures to communicative participation was assessed using multiple linear regression.ResultsFifty seven people living with ALS participated in the study (mean age = 61.1 years). Acoustic and self‐report measures of speech and bulbar function were moderately to highly associated with communicative participation (Spearman rho coefficients ranged from rs = 0.48 to rs = 0.77). A regression model including participant age, sex, articulation rate, and percent pause time accounted for 57% of the variance of communicative participation ratings.DiscussionEven though PALS with slowed articulation rate and increased pausing may convey their message clearly, these speech features predict communicative participation restrictions. The identification of quantitative speech features, such as articulation rate and percent pause time, is critical to facilitating early and targeted intervention and for monitoring bulbar decline in ALS.

AbstractAn 11‐year‐old female was referred from an outside institution after a diagnostic biopsy and subsequent excision of a progressively enlarging reddish‐brown nodule demonstrated features concerning for a balloon cell nevus with severe atypia versus a high‐grade melanocytoma. Upon review of the initial biopsy specimen and molecular data, we favored the diagnosis to be consistent with a high‐grade melanocytoma with balloon cell changes while considering the possibility of balloon cell melanoma due to concerning histopathologic and genetic abnormalities. In this case study, we discuss critical diagnostic considerations in this rare pediatric case and highlight important pathologic and clinical features of melanocytomas and balloon cell melanoma.

AbstractBackground and PurposeIneffective esophageal motility (IEM) is the most frequently diagnosed esophageal motility abnormality and characterized by diminished esophageal peristaltic vigor and frequent weak, absent, and/or fragmented peristalsis on high‐resolution esophageal manometry. Despite its commonplace occurrence, this condition can often provoke uncertainty for both patients and clinicians. Although the diagnostic criteria used to define this condition has generally become more stringent over time, it is unclear whether the updated criteria result in a more precise clinical diagnosis. While IEM is often implicated with symptoms of dysphagia and gastroesophageal reflux disease, the strength of these associations remains unclear. In this review, we share a practical approach to IEM highlighting its definition and evolution over time, commonly associated clinical symptoms, and important management and treatment considerations. We also share the significance of this condition in patients undergoing evaluation for anti‐reflux surgery and consideration for lung transplantation.

Abstract Pegfilgrastim is a sustained-duration form of the granulocyte colony-stimulating factor filgrastim to which a polyethylene glycol molecule is covalently bound to the N-terminal methionine residue. Although rare, anaphylaxis to pegfilgrastim has been reported. Desensitization is a safe management option for drug hypersensitivity. To date, no desensitization protocols to pegfilgrastim have been reported. We present the case of a 36-year-old female diagnosed with breast cancer who was treated with paclitaxel and carboplatin every two weeks plus pegfilgrastim, to which she developed anaphylaxis. The lack of alternative treatment options led to the decision to proceed with desensitization, which was carried out successfully with a novel 12-step, 1-bag protocol, allowing the safe resumption of the medication. Although the mechanisms underlying hypersensitivity to pegfilgrastim remain unknown, clinicians must be aware of the possibility of anaphylaxis to this medication and of the available treatment options, such as desensitization. To our knowledge, this is the first report of a desensitization protocol to pegfilgrastim.

Lay Summary This retrospective study assessed the use of Janus kinase inhibitors in treating chronic pouchitis. While showing relative safety, Janus kinase inhibitors demonstrated effectiveness in <50% of cases, cautioning against their use as first-line agents. Larger randomized trials are recommended for further investigation.

Abstract Aims Aortic valve calcification (AVC) is prognostic in patients with aortic stenosis (AS). We assessed the AVC prognostic value in non-severe AS patients. Methods and results We conducted a retrospective study of 395 patients with non-severe AS, LVEF ≥ 50%. The Agatston method was used for CT AVC assessment. The log-rank test determined the best AVC cut-offs for survival under medical surveillance: 1185 arbitrary unit (AU) in men and 850 AU in women, lower than the established cut-offs for severe AS (2064 AU in men and 1274 AU in women). Patients were divided into 3 AVC groups based on these cut-offs: low (<1185 AU in men and <850 AU in women), sub-severe (1185–2064 AU in men and 850–1274 AU in women), and severe (>2064 AU in men and >1274 AU in women). Of 395 patients (mean age 73 ± 12 years, 60.5% men, aortic valve area 1.23 ± 0.30 cm2, mean pressure gradient 28 ± 8 mmHg), 218 underwent aortic valve intervention (AVI) and 158 deaths occurred during follow-up, 82 before AVI. Median survival time under medical surveillance was 2.1 (0.7–4.9) years. Compared with the low AVC group, both sub-severe and severe AVC groups had higher risk for all-cause death under medical surveillance after comprehensive adjustment including echocardiographic AS severity and coronary artery calcium score (all P ≤ 0.006); while mortality risk was similar between sub-severe and severe AVC groups (all P ≥ 0.2). This mortality risk pattern persisted in the overall survival analysis after adjustment for AVI. AVI was protective of all-cause death in the sub-severe and severe AVC (all P ≤ 0.01), but not in the low AVC groups. Conclusion Sub-severe AVC is a robust risk stratification parameter in patients with non-severe AS and may inform AVI timing.
