Background: Since its first description in 2014, anti-inositol 1,4,5-trisphosphate receptor type 1 (ITPR1, also termed IP3R1) autoimmunity has been recognized as causing a clinically heterogeneous spectrum of symptoms. While first described in patients with autoimmune cerebellar ataxia, this facultative paraneoplastic disease has been associated also with peripheral neuropathy, dysautonomia, sleep disorders, neuropsychiatric/psychotic symptoms, and cognitive decline.

Methods: Retrospective case study.

Results: We report the case of a 58-year-old patient who was admitted with acute confusion, rapidly progressive cognitive decline, and hallucinations. A history of mild cognitive impairment over several years and low cerebrospinal fluid (CSF) amyloid beta-42 and elevated CSF …

Superior Transplant Recipient Outcome Prediction And Pathology Assessment Using Rapid Deep Learning Applied To Procurement Kidney Biopsies, Joseph P Gaut, Jon N Marsh, Ling Chen, Fan Zhang, Xiaobing Yu, Parker Wilson, Ta-Chiang Liu, S Joshua Swamidass

2020-Current year OA Pubs

Evaluating the suitability of deceased organ donor kidneys relies on clinical, laboratory, and biopsy data. Pathologist quantitation of glomerulosclerosis is a critical histologic parameter used in the decision to transplant. This is an arduous task with modest reproducibility and inconsistent correlation with graft outcomes. Prior work shows that deep learning methods automate glomerulosclerosis quantitation with performance superior to on-call pathologists. Extending beyond this prior work, in this study we find that deep learning glomerulosclerosis quantitation better correlates with graft outcomes. A customized and updated deep learning model was used to analyze 691 procurement biopsies of transplanted kidneys with an average …

2020-Current year OA Pubs

Intermittent fasting (IF) has gained attention as a potential intervention for cardiometabolic health, though its long-term effects remain unclear. In this randomized clinical trial, we assessed the impact of 6 months of IF on body composition, cardiovascular risk factors, and related molecular pathways in middle-aged (30-65 years) men and women with overweight (BMI 24.8-35 kg/m²). In this trial, 41 participants were randomized to either an intermittent fasting (IF) intervention or to maintain their habitual diet. The primary outcome (circulating CRP concentration) was previously reported; here, we present exploratory analyses focusing on metabolomic and transcriptomic responses. IF led to an 8% …

Escalated doses of radiotherapy associate with improved local control and overall survival (OS) in intrahepatic cholangiocarcinoma (iCCA), but personalization remains limited because conventional size-based CT criteria correlate poorly with outcomes. We hypothesized that quantitative enhancement measurements would better predict clinical outcomes and guide individualized RT optimization. In a retrospective cohort of 154 patients, we analyzed pre- and post-RT CT scans using quantitative European Association for Study of Liver (qEASL) to derive viable tumor volumes, comparing enhancement-based metrics with size-based RECIST and linking them to outcomes via survival and mathematical modeling. Change in enhancement volume was strongly associated with OS after …

Early Genetic Evolution Of Driver Mutations In Uveal Melanoma, James J Dollar, Kisha D Piggott, Et Al.

2020-Current year OA Pubs

Uveal melanoma (UM) is an aggressive eye cancer that frequently results in metastatic death despite successful primary tumor treatment. Subclinical micrometastasis is thought to occur early, when tumors are small and difficult to distinguish from benign nevi. However, the early genetic evolution of UM is poorly understood, and biomarkers for malignant transformation are lacking. Here, we perform integrated genetic profiling of 1140 primary UMs, including 131 small tumors. A clinically available 15-gene expression profile (15-GEP) prospectively validated by our group is more accurate than driver mutations for predicting patient survival. Small tumors are significantly more likely to be in earlier …

Faculty, Staff and Student Publications

Background: Stroke survivors often experience impaired upper extremity motor function due to abnormal muscle synergies. This pilot study evaluated the feasibility and preliminary effectiveness of electromyography-guided human-machine interaction training designed to expand the repertoire of intermuscular coordination patterns and improve upper extremity motor function in chronic stroke survivors.

Methods: Four chronic stroke survivors with mild-to-moderate upper extremity motor impairment and three age-matched healthy controls participated in a six-week electromyography-guided training intervention. Participants practiced selectively activating one elbow flexor muscle while suppressing another (brachioradialis or biceps brachii). Throughout the course of the intervention, the effect of the training on intermuscular coordination, …

A Nationwide Registry Study Of Surgical And Patient-Reported Outcomes Following Anterior Cervical Discectomy And Fusion: Part 2 - Cage With Versus Without Local Bone Graft, Daniel De Wilde, Victor Gabriel El-Hajj, Patrick Vigren, Victor E. Staartjes, Elias Atallah, Erik Edström, Adrian Elmi-Terander

Department of Neurosurgery Faculty Papers

BACKGROUND: Local bone grafts are commonly used as filling material in cages during anterior cervical discectomy and fusion (ACDF). Alternatively, cages without filling materials can be used. The literature comparing these approaches is limited, and their respective effects on patient-reported outcomes (PROM) have been scarcely studied. This study was conducted to compare surgical outcomes and PROMs between local bone graft-packed cages and empty cages in ACDF surgery.

METHODS: This observational study utilized data from the Swedish nationwide registry, Swespine. All adults who underwent ACDF between 2006 and 2020 were considered for inclusion. Exclusion criteria included missing baseline or outcome data. …

Longitudinal Quality Improvement Project To Increase Colorectal Cancer Screening For An Underserved Population In A Resident Physician-Led Primary Care Clinic., Vivek Vardhan Jasti, Sarah N Grebennikov, Mariah Barlow, David Y Lo, Shail M Govani, Miram Chan, Aimee E Willett, Christopher Barlow

Medical Education Articles

BACKGROUND: The overall rates of colorectal cancer (CRC) in the US population have been declining steadily over the past 30 years, in large part due to timely cancer screenings. Despite the emergence of new screening modalities, a large portion of the population has not completed CRC screening in accordance with guidelines. Adequate and timely screening can prevent or detect CRC in earlier stages. Various factors have been identified that influence screening completion. Lower screening rates have been associated with the underserved population, especially in the immigrant community and patients with inadequate access to healthcare. In the USA, primary care clinics …

Early-stage breast cancers resistant to neoadjuvant therapy (NAT), characterized by high residual cancer burden (RCB) after treatment, have an increased risk of metastatic recurrence. Here, we show that circulating tumor DNA (ctDNA) detected using a tumor-informed test (1) can improve risk stratification of patients with NAT-resistant tumors (RCB-II/RCB-III) and (2) predict response to NAT. Stratification using ctDNA status at pretreatment or post-NAT and ctDNA dynamics identified NAT-resistant tumors with a significantly decreased risk of metastatic recurrence. ctDNA clearance as early as week 3 across receptor subtypes predicted favorable responses to NAT, including immunotherapies. Interestingly, less than a fifth of patients …

Camidanlumab Tesirine For Relapsed Or Refractory Classic Hodgkin Lymphoma: A Phase 2 Study, Alex F Herrera, Nancy L Bartlett, Et Al.

2020-Current year OA Pubs

Outcomes in classic Hodgkin lymphoma (cHL) have steadily improved; however, additional therapies are needed for patients who relapse or do not respond to novel agents. Here, we report the efficacy and safety of camidanlumab tesirine (Cami), an anti-CD25 antibody-drug conjugate, in patients with relapsed/refractory cHL after brentuximab vedotin/programmed cell death protein 1 inhibitor therapies from the phase 2 ADCT-301-201 study. Eligible patients were adults with cHL who had received ≥3 previous lines of systemic therapy (or ≥2 if ineligible for hematopoietic stem cell transplant). Patients received 45 μg/kg Cami (IV, once every 3 weeks) in cycles 1 to 2, followed …

Association Of Pet4 Response With Outcomes Of Bv-Chp Vs Chop In The Echelon-2 Trial In Cd30+ Peripheral T-Cell Lymphoma, Swaminathan Iyer, Neha Mehta-Shah, Nancy L Bartlett, Et Al.

2020-Current year OA Pubs

In the phase 3 ECHELON-2 trial, brentuximab vedotin, cyclophosphamide, doxorubicin, and prednisone (BV-CHP) significantly improved progression-free survival (PFS) and overall survival (OS) compared with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) in patients with CD30+ peripheral T-cell lymphoma, benefits that were maintained at 5 years. Interim positron emission tomography (PET) scan can be used to assess prognosis and risk-stratify patients. The prognostic value of interim PET was assessed in this post hoc exploratory analysis from ECHELON-2, evaluating interim 18F-fluorodeoxyglucose PET scans after cycle 4 (PET4) and end-of-treatment-based response, and correlated with PFS per investigator and OS. PET4 response was determined by …

Deep Profiling Of Human T Cells Defines Compartmentalized Clones And Phenotypic Trajectories Across Blood And Tonsils, Suhas Sureshchandra, Elizabeth Levendosky, Allyssa Daugherty, Samuel J H Murphy, Chandrani Thakur, Naresha Saligrama, Et Al.

2020-Current year OA Pubs

98% of T cells reside in tissues, yet nearly all human T cell analyses are performed on peripheral blood. We performed single-cell sequencing of 5.7 million T cells from autologous blood and tonsils of ten donors. We identified distinct patterns of clonal expansion associated with tonsil-restricted phenotypes. Clonal sharing between blood and tonsils was lower than previous estimates and increased with age. Identical T cell receptor (TCR) sequences exhibited limited concordance in their phenotypes across compartments. Furthermore, location dictated the frequencies, clonal dominance, and phenotypes of antigen-specific T cells. Using immune organoids, we showed that antigen exposure drives functionally distinct …

Early detection of lung cancer is crucial for improving patient outcomes. However, accurately diagnosing invasive pulmonary nodules and predicting tumor invasiveness remain major clinical challenges. Given the established role of immune dysfunction in cancer development, we hypothesize that peripheral immune profiling could provide a strategy for managing pulmonary nodules. In this multi-center, prospective study, we combine peripheral immune profiling via mass cytometry with machine learning algorithms to develop an integrated pulmonary nodule management platform. This platform accurately distinguishes invasive from non-invasive pulmonary nodules (AUC = 0.952), outperforming established clinical and radiomics-based models. Furthermore, it effectively predicts tumor invasiveness, differentiating minimally …

BACKGROUND: Previous clinical, radiological and machine learning studies have predicted 90-day outcomes following subarachnoid hemorrhage (SAH). The present study was designed to determine whether early changes in mRNA expression of immune, clotting and other genes expressed in peripheral blood can predict patient outcomes at 90 days after SAH and possibly provide insights into the molecular factors that promote good versus poor outcomes.

METHODS: Peripheral blood was drawn after SAH and from vascular risk factor controls (VRFC) and RNAseq performed to measure mRNA expression. A mixed effects regression model identified potential predictors and machine learning algorithms derived the best predictors of …

Can Cta-Based Machine Learning Identify Patients For Whom Successful Endovascular Stroke Therapy Is Insufficient?, Jerome A Jeevarajan, Yingjun Dong, Anjan Ballekere, Sergio Salazar Marioni, Arash Niktabe, Rania Abdelkhaleq, Sunil A Sheth, Luca Giancardo

Faculty, Staff and Student Publications

Background and purpose: Despite advances in endovascular stroke therapy (EST) devices and techniques, many patients are left with substantial disability, even if the final infarct volumes (FIVs) remain small. Here, we evaluate the performance of a machine learning (ML) approach by using pretreatment CTA to identify this cohort of patients that may benefit from additional interventions.

Materials and methods: We identified consecutive subjects with large vessel occlusion (LVO) acute ischemic stroke (AIS) who underwent EST with successful reperfusion in a multicenter prospective registry cohort. We included only subjects with FIV < 30 mL and recorded 90-day outcome (mRS). A deep learning model was pretrained and then fine-tuned to predict 90-day mRS 0-2 by using pretreatment CTA images (DeepsymNet-v3 model pretrained on radiology reports and fine-tuned on detection of unexpected clinical outcomes using brain CTA images [DSN-CTA] model). The primary outcome was the predictive performance of the DSN-CTA model compared with a logistic regression model with clinical variables, measured by the area under the receiver operating characteristic curve (AUROC).

Results: The DSN-CTA model was pretrained on 1542 subjects and …

Brain Metabolic-Functional (De)Coupling From Health To Glioma Dysfunction, G Vallini, G Baron, E Silvestri, T Volpi, A G Vlassenko, M S Goyal, A Chiuso, D Cecchin, M Corbetta, A Bertoldo

2020-Current year OA Pubs

The interplay between brain metabolism and function supports the brain's adaptive capacity in cognitively demanding processes. Prior work has linked glucose metabolism to resting-state fMRI activity, but often overlooks both hemodynamic confounders in the BOLD signal and the brain's dynamic nature. To address this, we employed a novel effective connectivity decomposition, separating symmetric partial covariance, capturing "true" statistical dependencies between regions, from antisymmetric differential covariance, reflecting directional brain flow. In 42 healthy subjects, we show that partial covariance corresponds to metabolic connectivity across regions, while node directionality relates to standardized uptake value ratio, a proxy for local glucose consumption. We …

We analyze 10,986 participants (mean age 77; 63% women; 54% non-White) across seven U.S. cohorts to study the relationship between mitochondrial DNA (mtDNA) heteroplasmy and nuclear DNA methylation. We identify 597 CpGs associated with heteroplasmy burden, generally showing lower methylation. These CpGs are enriched in dynamically regulated island shores and depleted in CpG islands, indicating involvement in context-specific rather than constitutive gene regulation. In HEK293T cells, we introduce a truncating mtDNA mutation (MT-COX3, mt.9979) and observe a positive correlation between variant allele fraction and methylation at cg04569152, supporting a direct mtDNA-nDNA epigenetic link. Many heteroplasmy-associated CpGs overlap with known methylation-trait …

UNLABELLED: Triple-negative breast cancer (TNBC) is an aggressive subtype of breast cancer lacking targeted therapies. Although aberrant N-glycosylation is a hallmark of malignancy, the specific roles of core-fucosylated (CF) and outer arm-fucosylated (OAF) N-glycans in TNBC progression and patient survival remain underexplored. This study utilized multiplexed glycomics by matrix-assisted laser desorption/ionization imaging mass spectrometry to spatially profile 348 N-glycans in 59 TNBC tumors with clinical characteristics including survival data. Spatial analysis revealed distinct localization patterns of CF and OAF isomers within tumor microenvironments. Strikingly, OAF glycans, but not CF, were strongly associated with tumor stage, with expression increasing from stage …

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Background: Burnout and secondary traumatic stress (STS) are common among therapists working with trauma-exposed clients, which can negatively impact them professionally and personally. The shared trauma of war exposure may put therapists at greater risk. To help support their wellbeing, an eight-session course was offered to Ukrainian therapists following training in Trauma-Focused Cognitive Behavioral Therapy (TF-CBT). This course involves therapists personally utilizing the PRACTICE skills taught to clients in TF-CBT for professional and personal benefit.

Objective: The objective was to gather preliminary evidence on the potential impact of implementing the course with Ukrainian therapists providing TF-CBT during a period of …
