BACKGROUND: Malignant peripheral nerve sheath tumor (MPNST) is an aggressive and poorly understood malignant neoplasm. Even in the setting of multimodal therapy, the clinical course of MPNST is frequently marked by metastatic conversion and poor overall prognosis, with optimal treatment paradigms for this rare tumor unknown.

METHODS: We reviewed the medical records and histopathology of 54 consecutive patients who were treated at University of California San Francisco between 1990 and 2018.

RESULTS: Our cohort consisted of 24 male and 30 female patients (median age 38 years). Fédération Nationale des Centres de Lutte Contre Le Cancer (FNCLCC) sarcoma grading criteria segregated …

Physician Attitudes Towards-And Adoption Of-Mobile Health, Tracie Kong, Mary Morgan Scott, Yang Li, Cynthia Wichelman

2020-Current year OA Pubs

OBJECTIVE: Smartphone apps and mobile devices are an emerging method of healthcare data collection. This study sought to understand how physicians currently view mobile health (mHealth) technologies and use them in patient care.

METHODS: A total of 186 physicians affiliated with Washington University School of Medicine in St. Louis, Missouri, USA completed a survey in 2016 regarding their current implementation of mHealth technologies for patient care and support for further development.

RESULTS: More than half of respondents were willing to discuss health apps and mobile devices with patients. However, most were not currently recommending them to patients. Apps/devices that encouraged …

Semi-Automated Segmentation Of The Lateral Periventricular Regions Using Diffusion Magnetic Resonance Imaging, Albert M Isaacs, Rowland H Han, Christopher D Smyser, David D Limbrick, Joshua S Shimony

2020-Current year OA Pubs

The lateral ventricular perimeter (LVP) of the brain is a critical region because in addition to housing neural stem cells required for brain development, it facilitates cerebrospinal fluid (CSF) bulk flow and functions as a blood-CSF barrier to protect periventricular white matter (PVWM) and other adjacent regions from injurious toxins. LVP injury is common, particularly among preterm infants who sustain intraventricular hemorrhage or post hemorrhagic hydrocephalus and has been associated with poor neurological outcomes. Assessment of the LVP with diffusion MRI has been challenging, primarily due to issues with partial volume artifacts since the LVP region is in close proximity …

Improving The Implementation And Sustainment Of Evidence-Based Practices In Community Mental Health Organizations: A Study Protocol For A Matched-Pair Cluster Randomized Pilot Study Of The Collaborative Organizational Approach To Selecting And Tailoring Implementation Strategies (Coast-Is), Byron J Powell, Amber D Haley, Sheila V Patel, Lisa Amaya-Jackson, Beverly Glienke, Mellicent Blythe, Rebecca Lengnick-Hall, Stacey Mccrary, Rinad S Beidas, Cara C Lewis, Gregory A Aarons, Kenneth B Wells, Lisa Saldana, Mary M Mckay, Morris Weinberger

BACKGROUND: Implementing and sustaining evidence-based programs with fidelity may require multiple implementation strategies tailored to address multi-level, context-specific barriers and facilitators. Ideally, selecting and tailoring implementation strategies should be guided by theory, evidence, and input from relevant stakeholders; however, methods to guide the selection and tailoring of strategies are not well-developed. There is a need for more rigorous methods for assessing and prioritizing implementation determinants (barriers and facilitators) and linking implementation strategies to determinants. The Collaborative Organizational Approach to Selecting and Tailoring Implementation Strategies (COAST-IS) is an intervention designed to increase the effectiveness of evidence-based practice implementation and sustainment. COAST-IS …

Noninvasive Detection Of Graft Injury After Heart Transplant Using Donor-Derived Cell-Free Dna: A Prospective Multicenter Study, Kiran K Khush, Jignesh Patel, Sean Pinney, Andrew Kao, Rami Alharethi, Eugene Depasquale, Gregory Ewald, Peter Berman, Manreet Kanwar, David Hiller, James P Yee, Robert N Woodward, Shelley Hall, Jon Kobashigawa

Standardized donor-derived cell-free DNA (dd-cfDNA) testing has been introduced into clinical use to monitor kidney transplant recipients for rejection. This report describes the performance of this dd-cfDNA assay to detect allograft rejection in samples from heart transplant (HT) recipients undergoing surveillance monitoring across the United States. Venous blood was longitudinally sampled from 740 HT recipients from 26 centers and in a single-center cohort of 33 patients at high risk for antibody-mediated rejection (AMR). Plasma dd-cfDNA was quantified by using targeted amplification and sequencing of a single nucleotide polymorphism panel. The dd-cfDNA levels were correlated to paired events of biopsy-based diagnosis …

B Cell-Mediated Antigen Presentation Through Mhc Class Ii Is Dispensable For Atherosclerosis Progression, Jesse W Williams, Andrew Elvington, Skyler Kessler, Mary Wohltmann, Gregory F Wu, Gwendalyn J Randolph

2020-Current year OA Pubs

Depletion of B cells attenuates plaque development and modulates T cell responses in mouse models of atherosclerosis, suggesting that Ag presentation by B cells may promote disease progression. Thus, we set out to determine the role of B cell-mediated MHC class II (MHC II) Ag presentation during atherosclerotic plaque development. We developed murine conditional MHC II deletion and expression systems under control of the B cell-restricted CD19 promoter in an experimental model of atherosclerosis. Mice lacking MHC II expression only on B cells exhibited systemic shifts in germinal center and marginal zone B cell populations, leading to a reduced Ab …
