Introduction: Few studies have reported the predictive factors related to mortality in patients with cranio-cervical artery dissections (CCAD). Our aim was to investigate the predictors related to in-hospital mortality in patients with CCAD and its subgroups.
Methods: Sixty-seven patients diagnosed with carotid artery dissection (CAD) or vertebral artery dissection (VAD), admitted to our clinic between 2000 and 2013, were retrospectively reviewed. Age, gender, modified Rankin Scale scores (pre-stroke and at admission), clinical presentation type, location of the dissection, risk factors, and treatments were analyzed as mortality-related prognostic factors. Of the 67 patients, 12 (17.9%) died, five (7.46%) with CAD and seven (10.44%) with VAD. We compared the prognostic characteristics of the surviving versus deceased patients with CCAD and in the subgroups with CAD and VAD.
Results: Age above 45 years, severe disability at admission, presentation with stroke, and intracranial VAD occurred more frequently in deceased patients and were independent variables related to mortality in patients with CCAD and its subgroup with VAD. Severe disability at admission alone was related to mortality in patients with CAD. Hypertension and hypercholesterolemia were independent variables related to mortality in patients with CCAD.
Conclusion: Severe disability at admission was a mortality predictor in both CAD and VAD. Although the initial severity of stroke is reportedly related to poor outcomes in patients with CCAD, it has not previously been directly identified as a predictor of mortality in patients with CAD or VAD.

The Association of Epstein-Barr Virus Donor and Recipient Serostatus With Outcomes After Kidney Transplantation : A Retrospective Cohort Study.
Ann Intern Med
January 2025
Renal-Electrolyte Division, University of Pittsburgh Medical Center, Pittsburgh, Pennsylvania (M.C.-P., R.B.M., C.M.P.).
Background: Prior studies indicate that 1% to 4% of Epstein-Barr virus (EBV)-seronegative recipients of EBV-seropositive donor (EBV D+/R-) kidneys develop posttransplant lymphoproliferative disorder (PTLD). However, these estimates are based on limited data that lack granularity.
Objective: To determine the associations between pretransplant EBV D+/R- and recipient EBV-seropositive status (R+) and the outcomes of PTLD and graft and patient survival among adult kidney transplant recipients.
Chondrosarcomas are the second most common primary bone sarcoma. Due to chondrosarcomas relative resistance to chemotherapy and radiation, surgical treatment has become the mainstay treatment option. The purpose of our study was to understand the proportion of patients in this population who undergo non-operative treatment options secondary to various reasons and analyze the difference in survival as well as patient and cancer specific characteristics between the two groups.

Neurology
February 2025
Department of Neurology, Department of Stroke, University Hospital Cleveland Medical Center, Case Western Reserve University, Cleveland, OH.
Background And Objectives: Although previous trials have established the efficacy and safety of endovascular thrombectomy (EVT) in large ischemic core strokes, most of them excluded patients with extracranial internal carotid artery (e-ICA) occlusion. We aimed to compare outcomes in patients with e-ICA occlusion and large ischemic core infarcts treated with EVT vs medical management (MM).
Methods: This was a secondary analysis of the SELECT2 trial, a randomized controlled trial conducted at 31 international sites.
Correlates of Cetuximab Efficacy in Recurrent and Metastatic Head and Neck Squamous Cell Carcinoma Previously Treated With Immunotherapy.
JCO Precis Oncol
January 2025
Department of Medicine, Massachusetts General Hospital, Boston, MA.
Purpose: Immune checkpoint inhibitors (ICIs) are now first-line therapy for most patients with recurrent/metastatic head and neck squamous cell carcinoma (R/M HNSCC), and cetuximab is most often used as subsequent therapy. However, data describing cetuximab efficacy in the post-ICI setting are limited.
Methods: We performed a single-institution retrospective analysis of patients with R/M HNSCC treated with cetuximab, either as monotherapy or in combination with chemotherapy, after receiving an ICI.
Autoantibody clusters in childhood-onset systemic lupus erythematosus: Insights from a multicenter study with 912 patients.
Lupus

Pediatric Rheumatology Unit, Instituto da Criança e do Adolescente, Hospital das Clínicas HCFMUSP, Sao Paulo, Brazil.
To identify clusters of autoantibodies in a large cSLE population and to verify possible associations between different autoantibody clusters and the following variables: demographic data, cumulative clinical and laboratory manifestations, disease activity, cumulative damage and mortality. A cross-sectional study was performed in 27 Pediatric Rheumatology University centers, including 912 cSLE patients. The frequencies of seven selected autoantibodies (anti-dsDNA, anti-Ro/SSA, anti-La/SSB, anti-Sm, anti-RNP, aCL IgM and/or IgG and LA) were used for cluster analysis using the K-means method.
