Abstract Study Design: Secondary outcome measures analysis of a randomized, controlled study. Objectives: To assess the effects of hybrid-functional electrical stimulation (FES) rowing, arms only (AO) rowing and waitlist (WL) controls on pain, pain interference, and depression in individuals with spinal cord injury (SCI). Setting: Outpatient rehabilitation networks Methods: 44 participants were randomly assigned to FES (n = 19), AO (n= 12) or WL (n=13). The FES group completed 6 months of rowing scheduled 3 times per week. Individuals in the AO and WL groups were allowed to cross over to FES rowing after 6 months and were included in subsequent analyses of the effects of FES rowing. Rowing distance and intensity was logged, and maximal oxygen consumption (VO2max) measures were obtained before and after the intervention. Changes in the Patient-Reported Outcomes Measurement Information System (PROMIS-56) derived pain interference, pain, and depression scores were analyzed. Results: FES-rowing led to modest improvements in depression, AO led to modest improvements in pain intensity, and WL did not improve pain nor depression. After incorporating individuals who crossed over to FES rowing, we observed modest but significant improvement in depression scores but not in pain. Among the participants who benefited from the FES intervention, the reduction in depression was correlated to the average weekly rowing distance (r2=0.79 p=0.0001). Conclusions: 6 months of FES rowing spent in a supportive environment can help persons with spinal cord injuries alleviate moderate depression in a dose-dependent manner.

ObjectiveThe aim was to evaluate representation of women in otolaryngology by examining authorship of research publications and presentations, awards, research grants, leadership, and membership in related organizations.MethodsAuthorship was reviewed from articles published in three otolaryngology journals from 2000 through 2021 to assess the frequency and percentages of female and combination of male and female gender authorship. Gender was evaluated for poster and scientific abstract presentations from 2007 to 2021. Gender representation was reviewed for institutional and society leadership positions, award, and grant recipients in the American Laryngological Society (ALA). Changes in the frequency of female and combination of male and female gender authorship over time were examined with Cochran‐Armitage test for trend.ResultsA total of 16,921 articles, 1,017 presentations, 480 leadership positions, 129 president positions, and 1,137 awards and grants were studied. Women were first authors in 4,153 (24.9%) and last authors in 2,935 (17.8%) published articles for which gender could be determined. Women were first authors in 372 (37.4%) presentations and last authors in 199 (20.2%). Most presentations had a combination of male and female presentation authorship (630, 68%). Women held 69 (14.4%) leadership positions. Of the award and grant recipients, 327 (28.8%) were female. Significant trends were observed for increasing female representation (first authorship publications increased 69.9% from 2000 to 2020, first authorship presentations increased 73.9% from 2007 to 2013, p < 0.001; leadership and awards from 3% to 18% representation, p = 0.02).ConclusionThe proportion of women receiving awards and holding leadership positions is increasing. Efforts that promote gender diversity may further increase representation of women in otolaryngology literature and among the grant and award winners.Level of EvidenceNA Laryngoscope, 134:2144–2152, 2024

Background: Cutaneous malignant mixed tumor (MMT) is a rare sweat gland–derived tumor characterized by admixed malignant epithelial cells and chondromyxoid stroma. Approximately 50 cases have been described in the literature. Metastasis, which may occur in more than one-third of cases, is most common in the lung. Methods: We summarized the clinicopathologic features of a patient with cutaneous MMT metastatic to the lungs. A literature review of similar cases was completed using Web of Science, Scopus, and PubMed databases. Results: A woman in her 70s presented with an enlarging mass on her left eyebrow; histopathologic examination showed large islands of atypical cells with increased mitotic activity, admixed with necrosis on a background of fibrotic and chondromyxoid stroma. Multiple lung nodules were identified during follow-up. Examination of a pulmonary core needle biopsy specimen was consistent with metastatic cutaneous MMT. Literature review identified 10 cases published between 1980 and 2017. Most primary tumors were large (≥4 cm). Local recurrence was uncommon, and the lung was the only metastatic site in 5 cases. Histopathologically, metastatic tumors were described as more cellular, with diminished stromal tissue compared with the primary lesion. Conclusion: This is 1 of the 11 reports of cutaneous MMT with metastasis to the lungs found in the English-language literature published after 1980. Of note, most reports were published before 1990, making this case study one of the few contemporary descriptions of cutaneous MMT with pulmonary metastases. We think that the present case report will increase the awareness of this rare tumor.

Abstract The absence of a standardized definition for graft-versus-host disease (GVHD) flares and data on its clinical course are significant concerns. We retrospectively evaluated 968 patients across 23 Mount Sinai Acute GVHD International Consortium (MAGIC) transplant centers who achieved complete response (CR) or very good partial response (VGPR) within 4 weeks of treatment. The cumulative incidence of flares within 6 months was 22%, and flares were associated with a higher risk of nonrelapse mortality (NRM; adjusted hazard ratio [aHR], 4.84; 95% confidence interval [CI], 3.19-7.36; P &lt; .001). Flares were more severe (grades 3/4, 41% vs 16%; P &lt; .001) and had more frequent lower gastrointestinal (LGI) involvement (55% vs 32%; P &lt; .001) than the initial GVHD. At CR/VGPR, elevated MAGIC biomarkers predicted the future occurrence of a flare, along with its severity and LGI involvement. In multivariate analyses, higher Ann Arbor (AA) biomarker scores at CR/VGPR were significant risk factors for flares (AA2 vs AA1: aHR, 1.81 [95% CI, 1.32-2.48; P = .001]; AA3 vs AA1: aHR, 3.14 [95% CI, 1.98-4.98; P &lt; .001]), as were early response to initial treatment (aHR, 1.84; 95% CI, 1.21-2.80; P = .004) and HLA-mismatched unrelated donor (aHR, 1.74; 95% CI, 1.00-3.02; P = .049). MAGIC biomarkers also stratified the risk of NRM both at CR/VGPR and at the time of flare. We conclude that GVHD flares are common and carry a significant mortality risk. The occurrence of future flares can be predicted by serum biomarkers that may serve to guide adjustment and discontinuation of immunosuppression.

Intrathecal synthesis of central nervous system (CNS)-reactive autoantibodies is observed across patients with autoimmune encephalitis (AE), who show multiple residual neurobehavioral deficits and relapses despite immunotherapies. We leveraged two common forms of AE, mediated by leucine-rich glioma inactivated-1 (LGI1) and contactin-associated protein-like 2 (CASPR2) antibodies, as human models to comprehensively reconstruct and profile cerebrospinal fluid (CSF) B cell receptor (BCR) characteristics. We hypothesized that the resultant observations would both inform the observed therapeutic gap and determine the contribution of intrathecal maturation to pathogenic B cell lineages. From the CSF of three patients, 381 cognate-paired IgG BCRs were isolated by cell sorting and scRNA-seq, and 166 expressed as monoclonal antibodies (mAbs). Sixty-two percent of mAbs from singleton BCRs reacted with either LGI1 or CASPR2 and, strikingly, this rose to 100% of cells in clonal groups with ≥4 members. These autoantigen-reactivities were more concentrated within antibody-secreting cells (ASCs) versus B cells ( P < 0.0001), and both these cell types were more differentiated than LGI1- and CASPR2-unreactive counterparts. Despite greater differentiation, autoantigen-reactive cells had acquired few mutations intrathecally and showed minimal variation in autoantigen affinities within clonal expansions. Also, limited CSF T cell receptor clonality was observed. In contrast, a comparison of germline-encoded BCRs versus the founder intrathecal clone revealed marked gains in both affinity and mutational distances ( P = 0.004 and P < 0.0001, respectively). Taken together, in patients with LGI1 and CASPR2 antibody encephalitis, our results identify CSF as a compartment with a remarkably high frequency of clonally expanded autoantigen-reactive ASCs whose BCR maturity appears dominantly acquired outside the CNS.

Abstract Recent advances in the field of immuno‐oncology have brought transformative changes in the management of cancer patients. The immune profile of tumours has been found to have key value in predicting disease prognosis and treatment response in various cancers. Multiplex immunohistochemistry and immunofluorescence have emerged as potent tools for the simultaneous detection of multiple protein biomarkers in a single tissue section, thereby expanding opportunities for molecular and immune profiling while preserving tissue samples. By establishing the phenotype of individual tumour cells when distributed within a mixed cell population, the identification of clinically relevant biomarkers with high‐throughput multiplex immunophenotyping of tumour samples has great potential to guide appropriate treatment choices. Moreover, the emergence of novel multi‐marker imaging approaches can now provide unprecedented insights into the tumour microenvironment, including the potential interplay between various cell types. However, there are significant challenges to widespread integration of these technologies in daily research and clinical practice. This review addresses the challenges and potential solutions within a structured framework of action from a regulatory and clinical trial perspective. New developments within the field of immunophenotyping using multiplexed tissue imaging platforms and associated digital pathology are also described, with a specific focus on translational implications across different subtypes of cancer. © 2024 The Authors.
