At more than 200 years, the maximum lifespan of the bowhead whale exceeds that of all other mammals. The bowhead is also the second-largest animal on Earth1, reaching over 80,000 kg. Despite its very large number of cells and long lifespan, the bowhead is not highly cancer-prone, an incongruity termed Peto’s paradox2. Here, to understand the mechanisms that underlie the cancer resistance of the bowhead whale, we examined the number of oncogenic hits required for malignant transformation of whale primary fibroblasts. Unexpectedly, bowhead whale fibroblasts required fewer oncogenic hits to undergo malignant transformation than human fibroblasts. …

Periostin Promotes Sarcoma Growth By Promoting Tumor-Associated Macrophage Migration And Differentiation, Jin-Fen Xiao, Kristin Ishaya, Emily Y Ko, Annaliese Fowler, Marina T Broz, Jlenia Guarnerio

Faculty, Staff and Student Publications

Soft-tissue sarcomas (STS) are characterized by abundant extracellular matrix (ECM) deposition, yet the functional contribution of specific ECM components remains poorly understood. In this study, we identify periostin (POSTN), a matricellular protein, as a regulator of sarcoma progression and the tumor immune microenvironment. Analysis of human sarcoma datasets revealed that high POSTN expression correlates with poor prognosis and elevated expression of ECM-related and myeloid cell–associated genes. In murine genetic models of sarcoma, tumors expressing high levels of Postn displayed enhanced expression of ECM genes and monocyte-recruiting cytokines. Functional silencing of Postnin vivo reduced tumor growth without altering tumor cell …

Prone Percutaneous Jungbluth For Reduction Of Irreducible Posterior Pelvic Ring Injuries: A Technical Trick, Joseph M Radley, Jonathan A Copp, Daniel S Gloekler, Jonathan G Eastman

Faculty, Staff and Student Publications

Unstable pelvic ring injuries represent a challenge due to the complex anatomy. Further, surgical access to the pelvic ring is altered by patient positioning in the supine versus prone position. Certain injury patterns present with the posterior pelvis in a fixed displaced position. These injuries can be exceedingly challenging to reduce from a supine position. In the prone position, these injuries can be reduced more directly with an open approach, but this is associated with wound healing complications. The technical trick herein demonstrated a successful technique utilizing a large Jungbluth clamp percutaneously applied to the posterior superior iliac spines with …

Bayesian Integrated Learning Of Longitudinal Dose-Response Relationships Via Decentralized Clinical Trials, Jingyi Zhang, Tuo Wang, Yongming Qu, Fangrong Yan, Suyu Liu, Ruitao Lin

Faculty, Staff and Student Publications

Decentralized clinical trials (DCTs) extend trial activities beyond traditional sites, enhancing access, convenience, efficiency, and result generalizability. They are particularly promising for chronic conditions like diabetes and obesity, which require longer study durations to evaluate drug effects. However, decentralized data collection raises concerns about increased variability and potential biases. This paper presents a novel Bayesian integrated learning procedure to analyze dose-response relationships using longitudinal data from a phase II DCT that combines centralized and decentralized data collection. We generalize a parametric exponential decay model to handle mixed data sources and apply Bayesian spike-and-slab priors to address biases and uncertainties from …

Background: Muscular strength is a powerful marker of current health status and robust predictor of age-related disease and disability. Handgrip strength (HGS) using isometric dynamometry is a convenient, feasible, and widely used method of assessing muscular strength among people of all ages. While adult HGS norms have been published for many countries, no study has yet synthesized available data to produce international norms. The objective of this study was to generate international sex- and age-specific norms for absolute and body size-normalized HGS across the adult lifespan.

Methods: Systematic searches were conducted in 6 databases/web search engines (MEDLINE, SPORTDiscus, Embase, Web …

Reviewing Vascular Influences On Neuronal Migration, Cortical Development, And Neurodevelopmental Disorders: Focus On Autism, Adhd And Schizophrenia, Lalit K Ahirwar, Spiros L Blackburn, Devin W Mcbride, Peeyush Kumar T

Faculty, Staff and Student Publications

During cortical development, newly born neurons migrate radially or tangentially from their origin to expand the cortex. Simultaneously, neuron-derived factors support angiogenesis, and an elaborate network of blood cerebral vessels develops in the cortex. Traditionally, blood cerebral vessels were considered to support the growing cortex or migrating neurons by providing nutrients and oxygen. However, recent studies have shed light on Endothelial cells' influence on cortical development; they guide neuronal migration by providing molecular cues and structural support. Here, we review the current understanding of how CNS cerebral vessels support neurogenesis, neuronal migration, and the formation of the six-layer cortical structure …

Impact Of Postpartum Diagnosis On Survival Of Women With Inflammatory Breast Cancer, Jennifer H Chen, Rebecca S Slack Tidwell, Megumi Kai, Anthony Lucci, Wendy A Woodward, Helen M Johnson

Faculty, Staff and Student Publications

Background: Postpartum diagnosis of breast cancer confers increased risk of metastasis and death, possibly because of protumorigenic pathways that occur after weaning. We sought to evaluate the impact of postpartum diagnosis on survival in patients with inflammatory breast cancer (IBC).

Methods: We performed a retrospective analysis of patients with nonmetastatic IBC enrolled in a prospective registry (2007-2023). Kruskal-Wallis, χ2, and Fisher exact tests were used to compare between postpartum groups. The Kaplan-Meier method and log-rank tests were used for survival estimates.

Results: Among 320 patients with IBC, 25 (7.8%) were nulliparous, 31 (9.7%) were 0 to 5 years postpartum, 26 …

Bayesian Prediction Of Event Times Using Mixture Model For Blinded Randomized Controlled Trials, Jingyan Fu, Dan Zhao, Donia Skanji, Hua Liu, Rui Sammi Tang, Ying Yuan

Faculty, Staff and Student Publications

Accurate prediction of key milestone dates, such as the timing of interim and final analyses, is crucial in event-driven clinical trials with time-to-event endpoints. These predictions facilitate timely decision-making, enhance strategic planning and optimize resource allocation while minimizing patient exposure to potentially ineffective or harmful therapies. Existing methods for predicting event timing in blinded randomized clinical trials (RCTs) typically assume identical time-to-event distributions for the treatment and control arms, implying no treatment effect. This assumption fails when the treatment is more effective than the control, which is often the very outcome the trial seeks to detect, leading to biased predictions. …

Individualizing Nsaid Therapy In Axial Spondyloarthritis: N-Of-1 Trials With Bayesian Analysis, Mark C Hwang, Seokhun Kim, Shervin Assassi, Reyna Chavez, Joyce Samuel, Charles Green, Jon Tyson, John Reveille

Faculty, Staff and Student Publications

Objective: Axial spondyloarthritis (axSpA) is a chronic inflammatory disease predominantly affecting the spine and sacroiliac joints. NSAIDs are first-line therapy, but individual responses vary widely. We evaluated the efficacy and patient preference of three NSAIDs (celecoxib, meloxicam and naproxen) through Bayesian N-of-1 clinical trials to optimize axSpA management.

Methods: We conducted N-of-1 trials with 42 patients meeting ASAS criteria for axSpA. Each patient was asked to complete two cycles of randomized double-blind crossover comparisons of the three NSAIDs, each for 4 weeks. The primary end point was the change in the Ankylosing Spondylitis Disease Activity Score (ASDAS). Bayesian analysis assessed …

Impact Of Propofol Or Sevoflurane On The Renoprotective Effect Of Remote Ischaemic Preconditioning In Cardiac Surgery: The Hypnorenalrip Randomised Clinical Trial, Alexander Zarbock, Ludwig Maximilian Schöne, John A Kellum, Joachim Gerss, Raphael Weiss, Hendrik Booke, Melanie Meersch

Faculty, Staff and Student Publications

Background: Remote ischaemic preconditioning (RIPC) might reduce acute kidney injury after cardiac surgery. Protective effects appear to be restricted to patients with early and transient increases in two cell cycle arrest markers, tissue inhibitor of metalloproteinases-2 (TIMP-2) and insulin-like growth factor-binding protein 7 (IGFBP7), in urine. Studies suggest that propofol can attenuate the preconditioning effect on the myocardium. This study investigated whether propofol diminishes the renoprotective effect associated with the early transient increases in TIMP-2 and IGFBP7.

Methods: This was a single-centre, prospective randomised double-blind 2×2 factorial clinical trial of high-risk patients undergoing cardiac surgery. Patients were randomised to receive …

Relative Biological Effectiveness-Clinical Practice At Us Proton Therapy Centers, Armin Lühr, Radhe Mohan, Anita Mahajan, Helen A Shih, Harald Paganetti

Faculty, Staff and Student Publications

Purpose: Proton therapy, with its high conformality and superior dose distribution, is becoming an increasingly prevalent modality in radiation oncology. Although a generic relative biological effectiveness (RBE) value of 1.1 for treatment planning has been adopted, evidence suggests that RBE varies with dose, linear energy transfer (LET), and biological endpoints. This variation raises concerns about underestimating the RBE-weighted dose, which may significantly impact treatment outcomes. To assess the awareness and management of RBE variability in clinical practice, we conducted a survey among US proton therapy centers.

Materials and methods: The survey consisted of 32 questions grouped into subtopics, such as …

Personalized Risk Prediction For Cancer Survivors: A Generalized Bayesian Semi-Parametric Model Of Recurrent Events With Competing Outcomes, Nam Hoai Nguyen, Seung Jun Shin, Elissa Dodd-Eaton, Jing Ning, Wenyi Wang

Faculty, Staff and Student Publications

Multiple primary cancers are increasingly more frequent due to improved survival of cancer patients. Characteristics of the first primary cancer largely impact the risk of developing subsequent primary cancers. Hence, model-based risk characterization of cancer survivors that captures patient-specific variables is needed for healthcare policy making. We propose a Bayesian semi-parametric framework, where the occurrence processes of the competing cancer types follow independent non-homogeneous Poisson processes and adjust for covariates including the type and age at diagnosis of the first primary. Applying this framework to a historically collected cohort with families presenting a highly enriched history of multiple primary tumors …

Halo Gravity Traction And Temporary Internal Distraction, Nicholas D. Fletcher, Anson G. Bautista, Joshua S. Murphy, K Aaron Shaw

Manuscripts, Articles, Book Chapters and Other Papers

Severe pediatric spinal deformities may require staged correction strategies to mitigate neurologic risk and optimize cardiopulmonary outcomes. This paper reviews two adjunctive techniques—halo gravity traction (HGT) and temporary internal distraction (TID)—used in the management of rigid scoliosis. HGT enables gradual preoperative spinal elongation and coronal/sagittal realignment, improving pulmonary function and nutritional status while reducing the need for three-column osteotomies. TID offers an internal, staged distraction approach for patients contraindicated for external traction, allowing incremental correction via posterior instrumentation followed by definitive fusion. Clinical studies report Cobb angle reductions of 30–80 %, with low rates of neurologic complications when neuromonitoring and …
