Contribution Of Left Supramarginal And Angular Gyri To Episodic Memory Encoding: An Intracranial Eeg Study., Daniel Y. Rubinstein, Liliana Camarillo-Rodriguez, Mijail D. Serruya, Nora A. Herweg, Zachary J. Waldman, Paul A. Wanda, Ashwini D. Sharan, Shennan A. Weiss, Michael R. Sperling

Department of Neurology Faculty Papers

The role of the left ventral lateral parietal cortex (VPC) in episodic memory is hypothesized to include bottom-up attentional orienting to recalled items, according to the dual-attention model (Cabeza et al., 2008). However, its role in memory encoding could be further clarified, with studies showing both positive and negative subsequent memory effects (SMEs). Furthermore, few studies have compared the relative contributions of sub-regions in this functionally heterogeneous area, specifically the anterior VPC (supramarginal gyrus/BA40) and the posterior VPC (angular gyrus/BA39), on a within-subject basis. To elucidate the role of the VPC in episodic encoding, we compared SMEs in the intracranial …

Incorporation Of A Machine Learning Algorithm With Object Detection Within The Thyroid Imaging Reporting And Data System Improves The Diagnosis Of Genetic Risk., Shuo Wang, Jiajun Xu, Aylin Tahmasebi, Kelly Daniels, Ji-Bin Liu, Joseph Curry, Elizabeth Cottrill, Andrej Lyshchik, John R Eisenbrey

Department of Radiology Faculty Papers

Background: The role of next generation sequencing (NGS) for identifying high risk mutations in thyroid nodules following fine needle aspiration (FNA) biopsy continues to grow. However, ultrasound diagnosis even using the American College of Radiology's Thyroid Imaging Reporting and Data System (TI-RADS) has limited ability to stratify genetic risk. The purpose of this study was to incorporate an artificial intelligence (AI) algorithm of thyroid ultrasound with object detection within the TI-RADS scoring system to improve prediction of genetic risk in these nodules.

Methods: Two hundred fifty-two nodules from 249 patients that underwent ultrasound imaging and ultrasound-guided FNA with NGS with …

Atrioventricular Nodal Reentrant Tachycardia Ablation With A Power-Controlled, Contact-Force Catheter., Chase J Contino, Max Weiss, Michael P Riley, Daniel R Frisch

Division of Cardiology Faculty Papers

Radiofrequency catheter ablation is a safe and effective treatment option for atrioventricular nodal reentrant tachycardia (AVNRT). A nonirrigated ablation catheter used in a temperature-controlled mode is traditionally used for AVNRT ablation due to the shallow lesion depth required for successful slow-pathway ablation. In this case, a nonirrigated ablation catheter established inadequate lesions to ablate the slow pathway successfully. The adoption of an irrigated contact-force ablation catheter used in a power-controlled mode was necessary to provide higher power and possibly create a deeper lesion to ablate the slow pathway successfully, thus eliminating AVNRT inducibility in this patient.

Combating Acquired Resistance To Mapk Inhibitors In Melanoma By Targeting Abl1/2-Mediated Reactivation Of Mek/Erk/Myc Signaling., Rakshamani Tripathi, Zulong Liu, Aditi Jain,, Anastasia Lyon, Christina Meeks, Dana Richards, Jinpeng Liu, Daheng He, Chi Wang, Marika Nespi, Andrey Rymar, Peng Wang, Melissa Wilson, Rina Plattner

Department of Medical Oncology Faculty Papers

Metastatic melanoma remains an incurable disease for many patients due to the limited success of targeted and immunotherapies. BRAF and MEK inhibitors reduce metastatic burden for patients with melanomas harboring BRAF mutations; however, most eventually relapse due to acquired resistance. Here, we demonstrate that ABL1/2 kinase activities and/or expression are potentiated in cell lines and patient samples following resistance, and ABL1/2 drive BRAF and BRAF/MEK inhibitor resistance by inducing reactivation of MEK/ERK/MYC signaling. Silencing/inhibiting ABL1/2 blocks pathway reactivation, and resensitizes resistant cells to BRAF/MEK inhibitors, whereas expression of constitutively active ABL1/2 is sufficient to promote resistance. Significantly, nilotinib (2^{nd …}

The Impact Of Prostate Cancer Treatment On Quality Of Life: A Narrative Review With A Focus On Randomized Data., James M Taylor, Victor E. Chen, Ryan C. Miller, Benjamin A. Greenberger

Department of Radiation Oncology Faculty Papers

Despite excellent oncologic outcomes, the management of localized prostate cancer remains complex and is dependent on multiple factors, including patient life expectancy, medical comorbidities, tumor characteristics, and genetic risk factors. Decades of iterative clinical trials have improved the optimization and utilization of surgical and radiation-based modalities, as well as their combinatorial use with anti-androgen and systemic therapies. While cure rates are high and converging on equivalent disease control should an upfront surgical or radiotherapeutic approach be optimized, the long-term side effects of surgical and radiation-based treatments can differ significantly in nature. Decisions regarding the selection of therapy are therefore best …

Thalamus And Focal To Bilateral Seizures: A Multiscale Cognitive Imaging Study., Lorenzo Caciagli, Luke A Allen, Xiaosong He, Karin Trimmel, Sjoerd B Vos, Maria Centeno, Marian Galovic, Meneka K Sidhu, Pamela J Thompson, Danielle S Bassett, Gavin P Winston, John S Duncan, Matthias J Koepp, Michael R Sperling

Department of Neurology Faculty Papers

OBJECTIVE: To investigate the functional correlates of recurrent secondarily generalized seizures in temporal lobe epilepsy (TLE) using task-based fMRI as a framework to test for epilepsy-specific network rearrangements. Because the thalamus modulates propagation of temporal lobe onset seizures and promotes cortical synchronization during cognition, we hypothesized that occurrence of secondarily generalized seizures, i.e., focal to bilateral tonic-clonic seizures (FBTCS), would relate to thalamic dysfunction, altered connectivity, and whole-brain network centrality.

METHODS: FBTCS occur in a third of patients with TLE and are a major determinant of disease severity. In this cross-sectional study, we analyzed 113 patients with drug-resistant TLE (55 …

Inpatient Hospital Performance Is Associated With Post-Discharge Sepsis Mortality., Nicholas M. Mohr, Alexis M. Zebrowski, David F. Gaieski, David G. Buckler, Brendan G. Carr

Department of Emergency Medicine Faculty Papers

BACKGROUND: Post-discharge deaths are common in patients hospitalized for sepsis, but the drivers of post-discharge deaths are unclear. The objective of this study was to test the hypothesis that hospitals with high risk-adjusted inpatient sepsis mortality also have high post-discharge mortality, readmissions, and discharge to nursing homes.

METHODS: Retrospective cohort study of age-qualifying Medicare beneficiaries with sepsis hospitalization between January 2013 and December 2014. Hospital survivors were followed for 180-days post-discharge, and mortality, readmissions, and new admission to skilled nursing facility were measured. Inpatient hospital-specific sepsis risk-adjusted mortality ratio (observed: expected) was the primary exposure.

RESULTS: A total of 830,721 …

The Difficult Clinical Decision Of Thrombolytic Therapy For Submassive Pulmonary Embolism In A Community Hospital., Qian Zhang, Jonathan Vayalumkal, John Ricely, Daniel L. Gray, Ahmad Raza

Abington Jefferson Health Papers

Submassive or intermediate-risk pulmonary embolism (PE) occurs when an acute PE episode is associated with radiographic evidence of right heart strain without hemodynamic instability. Further risk stratification is important in determining whether systemic thrombolytic therapy should be administered when weighing the risks and benefits. It includes the risk of death from acute PE versus the risk of bleeding. This decision could be further complicated in institutions where there is a lack of complete therapeutic options, which increases the importance of the expertise of a pulmonologist or an intensivist to decide whether rescue reperfusion is needed. We describe the case of …

Characterization Of Indeterminate Breast Lesions On B-Mode Ultrasound Using Automated Machine Learning Models, Shuo Wang, Sihua Niu, Enze Qu, Flemming Forsberg, Annina Wilkes, Alexander Sevrukov, Kibo Nam, Robert F. Mattrey, Haydee Ojeda-Fournier, John R. Eisenbrey

Department of Radiology Faculty Papers

Purpose: While mammography has excellent sensitivity for the detection of breast lesions, its specificity is limited. Adjunct screening with ultrasound may partially alleviate this issue, but also increases false positives, resulting in unnecessary biopsies. This study investigated the use of Google AutoML Vision (Mountain View, CA), a commercially available machine learning service, to both identify and characterize indeterminate breast lesions on ultrasound.

Methods: B-mode images from 253 independent cases of indeterminate breast lesions scheduled for core biopsy were used for model creation and validation. The performances of two sub-models from AutoML Vision, the image classification model and object detection model …

Release And Extraction Of Retained Subfoveal Perfluorocarbon Liquid Facilitated By Subretinal Bss, Vibration, And Gravity: A Case Report., Kosuke Takahashi, Shuhei Kimura, Mio Morizane Hosokawa, Yusuke Shiode, Shinichiro Doi, Ryo Matoba, Yuki Kanzaki, Yoshihiro Yonekawa, Yuki Morizane

Wills Eye Hospital Papers

BACKGROUND: Perfluorocarbon liquid (PFCL) is an effective surgical adjuvant in performing vitrectomy for severe vitreoretinal pathologies such as proliferative vitreoretinopathy and giant retinal tears. However, subretinal retention of PFCL can occur postoperatively and retained PFCL causes severe visual disorders, particularly when PFCL was retained under the fovea. Although several procedures have been proposed for subfoveal PFCL removal, such as direct aspiration or submacular injection of balanced salt solution (BSS) to dislodge the subfoveal PFCL, the retinal damage associated with these procedures has been a major problem. Here, we report a case of subfoveal retention of PFCL for which we performed …
