Study Design: A national prospective cervical spine surgery registry was developed to archive radiographic studies, patient-reported outcome measures (PROMs), and surgical implant data to assess long-term safety. Objective: To describe the design, development, funding, and implementation of a cervical spine data registry for 1000 patients with myelopathy and radiculopathy. Summary of Background Data: While surgery for cervical radiculopathy and myelopathy is safe and effective, there is significant practice variation among spine surgeons. While randomized clinical trials (RCTs) can provide high-quality comparative effectiveness data, RCTs lack the ability to evaluate the safety and effectiveness of various surgical procedures and implants among heterogenous real-world patient populations. The CSRS Registry was designed to collect patient demographics, outcomes, radiographic imaging, surgical approach, and implant data for the purpose of conducting high-quality research. Methods: Patients with cervical myelopathy or radiculopathy were enrolled in the CSRS National Registry. De-identified patient data, validated PROMs, radiographic data, and implant data were collected from multiple clinical sites across the United States. Results: One thousand patients [mean age, 58 y; 456 (46%) women] were enrolled, with 31% follow-up at 1 year. Five hundred ninety-two patients were diagnosed with radiculopathy, 252 with myelopathy, and 156 with radiculopathy and myelopathy. Patients had significant improvements in their PROMs after surgery. At 1 year, the mean NDI score improved from 37.2 to 20.9 ( P <0.001). The mean self-reported P-mJOA score at baseline was 14.2 and improved to 15.2 by 1 year ( P <0.001). Baseline CSDI score was 23.6 and improved with a 1-year decrease to an average score of 13.6 ( P <0.001). There was significant improvement in PROMIS-10 Physical Health score from 41.0 to 45.9 (n=311; P <0.001) at 1-year follow-up. Conclusions: The CSRS Registry has successfully collected clinical outcomes data that is being leveraged for comparative effectiveness research and evaluations of the long-term safety and effectiveness of spinal implants.

Abstract This retrospective analysis examined 15 years of autologous stem cell transplantation (ASCT) for light chain (AL) amyloidosis at the Mayo Clinic (2010-2024). We aimed to assess ASCT utilization trends, factors influencing practice changes, and current indications amid newer therapies. Four hundred and forty-one ASCTs were divided into cohort 1 (2010-2019) and cohort 2 (2020-2024), revealing a significant ASCT reduction in cohort 2 (385 vs 56, average 71% annual decrease). Cohort 2 patients were older, more likely to have relapsed/refractory disease, and had higher baseline bone marrow plasma cell burden compared to cohort 1. Pre-ASCT induction was more frequent in cohort 2 (89.3% vs 56.4%), with daratumumab (Dara)–cyclophosphamide-bortezomib-dexamethasone (CyBorD) replacing CyBorD as the predominant induction regimen. Lymphoma-based regimens were also more common in cohort 2 (15.1% vs 5.3%, P = .02). Day-100 satisfactory hematological response improved in cohort 2 (91.1% vs 72.7%, P = .001), although hematological complete response rates did not significantly differ (50.9% vs 38.8%, P = .09). In summary, there is a decrease in the utilization of ASCT in AL amyloidosis. This procedure is primarily reserved for patients with suboptimal responses, relapsed/refractory disease, lymphoplasmacytic clones (predominantly immunoglobulin M amyloidosis), or high bone marrow plasma cell burden (myeloma phenotype). This study underscores a significant shift in ASCT practice, driven by novel therapies, emphasizing more personalized management in AL amyloidosis.

Abstract Background and Objectives Research has established that unpaid family members, friends, or others who care for persons with dementia (ie, caregivers) may encounter socioemotional and physical health concerns as a consequence of providing extensive assistance. Similarly, caregivers for people living with traumatic brain injury (TBI) often experience a range of stressors and negative mental health outcomes due to care demands. Individuals with TBI often develop Alzheimer’s disease and Alzheimer’s disease-related dementia (AD/ADRD). This history of TBI may introduce complications to AD/ADRD caregiving. A comprehensive intervention grounded in the understanding of the complex caregiving context of both diagnoses is warranted to address the unique needs and concerns of TBI-AD/ADRD caregivers. Research Design and Methods This study evaluated the feasibility of the TBI-AD/ADRD Caregiver Support Intervention (TACSI) psychoeducational program, designed to support the unique subset of caregivers facing the challenge of assisting relatives with AD/ADRD and a history of TBI. TACSI, a 6-session telehealth intervention, provides tailored psychosocial and psychoeducational coaching. In partnership with the 2 national healthcare centers, 15 caregivers enrolled in the 3-month feasibility study evaluating the design and subsequent refinement of TACSI. Mixed methods data were collected from 3-month follow-up surveys and qualitative data from postintervention interviews. Results The feasibility, utility, and acceptance of TACSI were established. Caregivers liked the telehealth delivery and the personalized nature of TACSI, yet some expressed it would have been more beneficial earlier in their caregiving journey. Discussion and Implications Caregivers valued the TACSI program. Their feedback has been applied to improve TACSI content and delivery for a larger pilot randomized controlled trial that is currently underway.

Abstract We conducted this systematic review to evaluate outcomes of thrombolysis followed by anticoagulation vs anticoagulation alone in pediatric patients with venous thromboembolism (VTE). This systematic review addresses mortality, VTE resolution, recurrence, bleeding, and organ-specific outcomes in 5 PICO (population, intervention, comparison, outcomes) questions on thrombolysis across pulmonary embolism (PE), extremity deep vein thrombosis (DVT), right atrial thrombosis (RAT), cerebral sinus venous thrombosis (CSVT), and renal vein thrombosis (RVT). Meta-analysis reported risk ratios or differences (95% confidence intervals [CIs]), and absolute effects per 1000 patients. Certainty of evidence was assessed using GRADE (Grading of recommendation, assessment, Development, and Evaluation) guidelines. Thirteen nonrandomized studies were included and no randomized clinical trials addressed these questions. Thrombolysis might be associated with a higher risk of major bleeding, clinically relevant nonmajor bleeding, or unspecified bleeding with risk differences of 0.09 (95% CI, −0.06 to 0.23), 0.06 (95% CI, −0.11 to 0.22), and 0.09 (95% CI, −0.04 to 0.23), respectively. In PE with hemodynamic compromise, thrombolysis might be associated with a lower risk of mortality but conclusions on PE progression were uncertain in submassive PE. In DVT, thrombolysis may have little to no effect on mortality or thrombus resolution but might be associated with lower risk of postthrombotic syndrome. In RAT, thrombolysis might have little to no effect on thrombus resolution but a higher risk of major bleeding and mortality. For CSVT and RVT, the evidence was very limited. These findings were based on very-low-certainty evidence because of confounding and imprecision from small sample sizes. This systematic review highlights key challenges in developing recommendations for thrombolysis in children with VTE.

Objectives: To compare thresholds and accuracies of FIB-4, vibration-controlled transient elastography (VCTE), point shear wave elastography (pSWE), 2D shear wave elastography (2D-SWE), and MR elastography (MRE) for detecting hepatic fibrosis in patients with MASLD. Materials and Methods: Systematic searching of MEDLINE, EMBASE, Cochrane Library, Scopus, and the gray literature from inception to March 2024 was performed. Studies evaluating accuracies of FIB-4, VCTE, 2D-SWE, pSWE, and/or MRE for detecting significant (≥F2) and/or advanced (≥F3) hepatic fibrosis in MASLD patients compared to histology were identified. Full-text review and data extraction were performed independently by two reviewers. Multivariate meta-analysis and subgroup analyses were performed using index test and fibrosis grading. Risk of bias was assessed using QUADAS-2. Results: 207 studies with over 80,000 patient investigations were included. FIB-4 1.3 threshold sensitivity was 71% (95% CI 66–75%) for detecting advanced hepatic fibrosis, which improved to 88% (85–91%) using a <0.75 threshold. FIB-4 specificity using a 2.67 threshold was 96% (94–97%). Sensitivities of 88–91% were achieved using thresholds of 3.2 kPa for pSWE, 4.92 kPa for 2D-SWE, 7.18 kPa for VCTE, and 2.32 kPa for MRE. No significant differences were identified for sensitivities in subgroup analysis with thresholds between 7 and 9 kPa. Most imaging-based studies were high risk of bias for the index test. Conclusions: A FIB-4 threshold of <0.75 and modality-dependent thresholds (VCTE < 7 kPa; pSWE <3 kPa; 2D-SWE <5 kPa; and MRE <2.5 kPa) would achieve sensitivities of around 90% when defining low-risk MASLD in population screening. A modified two-tier algorithm aligning with existing Society of Radiologists in Ultrasound guidelines would improve risk stratification accuracies compared to existing guidelines by European and American liver societies.

Objectives: To analyze variations in patient characteristics, treatment patterns, clinical manifestations, clinical outcomes (i.e., response, flares and flare-free survival in HES; remission, relapses and relapse-free survival in EGPA; and overall survival), and healthcare resource utilization (HCRU) in patients with hypereosinophilic syndrome (HES) and eosinophilic granulomatosis with polyangiitis (EGPA) across five European countries. Methods: In two parallel, retrospective, non-interventional, longitudinal chart review studies (GSK ID: 214661 [EGPA] and 214657 [HES]), physicians collected data of patients they treated in France, Germany, Italy, Spain, and the UK from January 2015 to December 2019, with follow-up until August 2021. Country-level results are presented for each study; HES and EGPA data were pooled in a post hoc exploratory analysis. Results: Per-country, 22–26 HES- and 38–45 EGPA-treating physicians collected data from 52–62 (total 280) patients with HES and 80–85 (total 407) with EGPA. Patient sex and age at diagnosis differed across countries. Pooled HES/EGPA data revealed high oral corticosteroid (OCS) use in all countries (94.9% of patients; median [IQR] duration 20.7 [9.0, 33.8] months); immunosuppressive treatments and biologics use varied between countries (43.7–61.5% and 25.6–59.8%, respectively). The most frequent clinical manifestations were constitutional (51.6–78.8%) and lung (43.5–55.8%) in HES, and lung (41.3–67.9) and ENT (43.8–61.2) in EGPA. Pooled HCRU data showed country-level variation; 70.7–91.2% of patients had disease-related outpatient visits and 36.1–52.6% had ER visits or hospitalizations. Conclusions: Results demonstrate substantial disease burden, including high HCRU and extensive OCS use among patients with HES and EGPA in five European countries. The findings highlight the need for improved treatment strategies such as optimizing use of biologics to mitigate the reliance on corticosteroids.

AbstractTemporal bone en plaque meningiomas can present management challenges, particularly when accompanied by severe pain. We report the case of a 42-year-old woman who was initially diagnosed with chronic otitis media but was later found to have a painful left temporal bone en plaque meningioma. Despite conservative therapy, her pain progressed, prompting the decision to undergo surgical resection, which resulted in considerable pain relief. This report illustrates the influence of pain on surgical decision-making for temporal bone en plaque meningiomas and reviews the literature on their variable presentations and management strategies.

Abstract Background FGFR alterations are known to be driver alterations in several tumor types. We aimed to assess the efficacy of pemigatinib, an oral FGFR1-3 inhibitor, in patients with metastatic or unresectable colorectal cancer whose tumors harbored FGF/FGFR alterations. Patients and Methods The ACCRU-GI-1701 is a single-arm phase II trial which enrolled patients with previously treated FGF/FGFR-altered metastatic colorectal cancer to receive oral pemigatinib daily in 21-day cycles. The primary endpoint is objective response. Secondary endpoints include clinical benefit, progression-free survival, overall survival, quality of life, and adverse events (AEs). This trial was registered with ClinicalTrials.gov (NCT04096417). Results Of the 14 patients included in the interim analysis, the objective response rate as well as clinical benefit rate were 0%. Given these results, the trial closed to enrollment after stage one due to futility. A total of 42.9% of patients had at least one grade 3 or higher AE, the most common being anemia and fatigue. Conclusion Pemigatinib monotherapy did not lead to objective responses in patients with chemorefractory metastatic colorectal cancer harboring FGF/FGFR alterations, although it was overall relatively well tolerated with no new safety signals. Notably, 93% (n = 13) of patients had only FGF/FGFR mutations and amplifications; one patient had an FGFR3-WHSC1 fusion at a low cfDNA percentage (0.02%).

Abstract Rationale A subset of patients with group 1 pulmonary hypertension (PH) have superimposed left heart abnormalities with unclear metabolic implications. Objectives To compare serum/transpulmonary metabolome between group 1 PH stratified by heart failure with preserved ejection fraction (HFpEF) probability. Methods Patients with group 1 PH were stratified into low (&lt;25%) and high (⩾75%) HFpEF-ABA (age, body mass index, and atrial fibrillation) probability, with healthy control subjects and subjects with clinical HFpEF used for comparison of venous and transpulmonary metabolomics. Measurements and Main Results Group 1 PH + high HFpEF probability (n = 131) was associated with a significant increase in 207 metabolites (false discovery rate [FDR] P &lt; 0.05 and fold change &gt;1) (n = 193, t test) and a significant decrease in 231 metabolites (FDR P &lt; 0.05 and fold change &lt;1) (n = 193, t test) compared with group 1 PH + low HFpEF probability (n = 62). Group 1 PH + high HFpEF probability was associated with enhanced tryptophan metabolism with higher downstream kynurenine metabolite concentrations and lower serotonin concentrations (FDR P &lt; 0.002 for all, n = 193, t test). Linoleate (precursor to arachidonic acid and prostaglandins) and arginine and homoarginine (precursors to nitric oxide) were all lower in group 1 PH + high HFpEF probability (FDR P &lt; 0.03 for all, n = 193, t test). Metabolome changes in group 1 PH + high HFpEF probability overlapped with clinical HFpEF (n = 240) but were abnormal relative to control subjects (n = 85) (P &lt; 0.0001 for all, n = 456, t test). There was no evidence of differential transpulmonary uptake/release of most metabolites, suggesting probable nonpulmonary origin (except for serotonin, interaction P = 0.04; and kynurenine, interaction P = 0.03; n = 433, mixed model). Conclusions Patients with group 1 PH + high HFpEF probability have a unique metabolome characterized by enhanced tryptophan-kynurenine pathway breakdown, deficiency of amino acids (such as glycine and serine), lower serotonin, and decreased prostaglandin and nitric oxide precursors. Despite fulfilling clinical criteria for group 1 PH, these metabolome changes were comparable with clinical HFpEF, supporting biological overlap between these two forms of PH.
