Percutaneous image-guided thermal ablation is an established local curative-intent treatment technique for the treatment of primary and secondary malignant liver tumors. Whereas margin assessment after surgical resection can be accomplished with microscopic examination of the resected specimen, margin assessment after percutaneous thermal ablation relies on cross-sectional imaging. The critical measure of technical success is the minimal ablative margin (MAM), defined as the minimum distance between the tumor and the edge of the ablation zone. Traditionally, the MAM has been assessed qualitatively using anatomic landmarks, which has suboptimal accuracy and reproducibility and is prone to operator bias. Consequently, specialized software-based methods …

Glutamate Gating Of Ampa-Subtype Iglurs At Physiological Temperatures, Anish Kumar Mondal, Elisa Carrillo, Vasanthi Jayaraman, Edward C Twomey

Faculty, Staff and Student Publications

Ionotropic glutamate receptors (iGluRs) are tetrameric ligand-gated ion channels that mediate most excitatory neurotransmission1. iGluRs are gated by glutamate, where on glutamate binding, they open their ion channels to enable cation influx into postsynaptic neurons, initiating signal transduction1,2. The structural mechanics of how glutamate gating occurs in full-length iGluRs is not well understood. Here, using the α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid subtype iGluR (AMPAR), we identify the glutamate-gating mechanism. AMPAR activation by glutamate is augmented at physiological temperatures. By preparing AMPARs for cryogenic-electron microscopy at these temperatures, we captured the glutamate-gating mechanism. Activation by glutamate initiates ion channel opening that involves all ion …

Faculty, Staff and Student Publications

Objectives: This final post hoc analysis evaluated patient-reported outcomes from the Phase 3 MAIA study of daratumumab, lenalidomide, and dexamethasone (D-Rd) versus lenalidomide and dexamethasone (Rd) after median 64.5-month follow-up in transplant-ineligible patients with newly diagnosed multiple myeloma (NDMM), including patient subgroups.

Methods: Key scales from the EORTC QLQ-C30 (global health status [GHS], physical functioning, pain, and fatigue) were assessed. Scores were evaluated every 3 months for 1 year, then every 6 months until disease progression.

Results: The intent-to-treat population (n = 737) included 46.3% frail, 35.4% 70 to < 75 years old, and 43.6% ≥ 75 years old. D-Rd-treated patients showed improvements from baseline that were sustained over 5 years in the intent-to-treat population and across subgroups by age, frailty, and bone lesions. Greater proportions of patients treated with D-Rd versus Rd achieved minimally important changes for improvement at cycle 36 (year ~3) in GHS (odds ratio, 1.84 [95% CI, 1.16-2.91]), physical functioning (1.93 [1.18-3.14]), pain (1.41 [0.90-2.22]), and fatigue (2.00 [1.24-3.23]). Greater proportions of patients with bone lesions improved with D-Rd versus Rd on GHS and physical functioning.

Temporal Dynamics Of Bmp/Nodal Ratio Drive Tissue-Specific Gastrulation Morphogenesis, Alyssa A Emig, Megan Hansen, Sandra Grimm, Cristian Coarfa, Nathan D Lord, Margot Kossmann Williams

Faculty, Staff and Students Publications

Anteroposterior elongation of the vertebrate body plan is driven by convergence and extension (C&E) gastrulation movements in both the mesoderm and neuroectoderm, but how or whether molecular regulation of C&E differs between tissues remains an open question. Using a zebrafish explant model of anteroposterior axis extension, we show that C&E of the neuroectoderm and mesoderm can be uncoupled ex vivo, and that morphogenesis of individual tissues results from distinct morphogen signaling dynamics. Using precise temporal manipulation of BMP and Nodal signaling, we identify a critical developmental window during which high or low BMP/Nodal ratios induce neuroectoderm- or mesoderm-driven C&E, respectively. …

The Dialysis Foot- The Impact Of Presenting Estimated Glomerular Filtration Rate On Clinical Outcomes In Patients Hospitalized With Diabetic Foot Infections, Arthur Tarricone, Tyler L Coye, Allen Gee, Bijan Najafi, Michael C Siah, Lawrence A Lavery

Center on Aging Staff Publications

To evaluate the association between presenting estimated glomerular filtration rate (eGFR) and clinical outcomes in patients hospitalized with diabetic foot infections. This retrospective cohort study included 344 patients with moderate to severe diabetic foot infections. Patients were categorized into three groups based on presenting estimated eGFR: eGFR ≥60 (eGFR >60 mL/min), eGFR 30-60 (eGFR 30-60 mL/min) and eGFR < 30 (eGFR < 30 mL/min). Outcomes assessed included wound healing, time to heal, re-infection, amputation, mortality and re-hospitalization for infection. Compared with patients with eGFR < 30, patients with eGFR ≥60 had significantly lower rates of retinopathy, peripheral arterial disease and use of beta blockers or calcium channel blockers. Glycated haemoglobin levels were inversely related to eGFR, decreasing as eGFR severity increased. Haemoglobin levels were significantly lower, and inflammatory markers (ESR and CRP) were significantly higher in patients with eGFR < 30. There were no significant differences among eGFR groups in rates of wound healing, time to heal, re-infection or amputation. However, mortality increased with decreasing eGFR (1.9% in eGFR ≥60 vs. 3.2% in eGFR 30-60 vs. 8.1% in eGFR < 30; p = 0.04). Similarly, re-hospitalization for infection at a different site also increased with decreasing eGFR (20.5% in eGFR ≥60 vs. 28.1% in eGFR 30-60 vs. 48.4% in eGFR < 30; p <  0.01). In diabetic foot infections, presenting eGFR severity did not affect rates of wound healing, time to heal, re-infection or amputation. However, decreasing eGFR was associated with increased mortality and re-hospitalization for infection at a different site. In this study, presenting eGFR was not a predictive value for wound healing or time until healing, however was associated with rehospitalization and overall mortality this diabetic foot population.
