Net Effects Of Correlated Determinants Of Health Among U.S. Older Adults, Haomiao Jia, E I. Lubetkin

Publications and Research

Background

The health effect produced by a contributing factor alone may be different from the effect when other interacting factors are present. The effects of a set of contributors, estimated by regression coefficients, may be invalid or inappropriate if some of the predictors are correlated or the model has interaction and nonlinear terms. The net effect (NE) of a given contributing factor is the effect produced by the factor alone, not by other factors due to their correlations with the factor of interest. This study estimated NE of selected determinants of health for U.S. older adults.

Advancing Anesthesia Provider Proficiency In Airway Assessment Using Point-Of-Care Ultrasound: An Osce-Based Educational Initiative, Austin Fike, Trevor Jordan, Sam Sherrill Iii

Doctoral Projects

Airway management is one of the fundamental pillars of anesthesia. Traditionally, tools such as the Mallampati classification and the thyromental distance are used for airway assessment in the perioperative area. However, often, these methods fail to reliably predict difficult intubations. The use of point-of-care ultrasound (POCUS) has emerged as a valuable adjunct in airway assessment. However, a knowledge deficit exists among anesthesia providers regarding its application in airway assessments for perioperative adult patients. This doctoral project addressed the knowledge deficit in POCUS airway assessment among Certified Registered Nurse Anesthetists (CRNAs) and Student Registered Nurse Anesthetists (SRNAs) through the development and …

A Feasibility Study Of Sexual Organ-Dose Sparing Volumetric Modulated Arc Therapy In Female Low Rectal Cancer Patients Treated With Three-Dimensional Conformal Radiation Therapy, Margaret Downes, Victoria Olsen, Andre Williams, Rendi Sheu, Maria Thor, Lucy Greenwald, Vishruta Dumane, Kristin Hsieh, Ayesha Ali, Orly Morgan, Michael Buckstein, Deborah Marshall

Department of Radiation Oncology Faculty Papers

BACKGROUND: Sexual dysfunction is a significant toxicity of pelvic radiation therapy (RT) for female rectal cancer patients and may be more common with intensity-modulated techniques compared to three-dimensional conformal radiation therapy (3D-CRT). However, limited research has evaluated dose sparing of female sexual organs at risk (OARs), particularly erectile tissues that are critical for sexual function.

PURPOSE: This feasibility study aimed to demonstrate the practicality of contouring and sparing female sexual OARs in rectal cancer RT by generating sexual organ-sparing volumetric modulated arc therapy (SO-VMAT) plans from a small 3D-CRT cohort and comparing dose distributions to guide future planning.

Ribosomally synthesized and post-translationally modified peptides (RiPPs) are a promising source of new pharmaceuticals, yet the therapeutic potential of fungal RiPPs remains largely underexplored. Here, we report asperigimycins as a distinct class of fungal RiPPs, featuring a unique heptacyclic scaffold consisting of a benzofuranoindoline core and three additional macrocycles, primarily assembled by six distinct fungi-specific DUF3328 oxidases. Inspired by the enhancement of anticancer activity through the N-terminal pyroglutamate in naturally occurring asperigimycins C and D, we chemically modify the inactive asperigimycin B with a series of lipid substitutions at its N-terminus. A derivative with a C-11 linear fatty …

Department of Obstetrics and Gynecology Faculty Papers

Increasingly the value of gestational weight gain (GWG) as a useful measure to predict obstetric outcomes including cesarean section is being questioned. We will undertake a retrospective cohort study of recorded births in 2023 from 24 to 42 weeks' gestation for women aged from 16 to 49 years in the United States. Using multivariable Robust Poisson Regression, maternal body mass index (BMI) and BMI gain will be modelled on the primary outcome of cesarean delivery. The primary analysis will be restricted to nulliparous women if there is interaction between parity and BMI or BMI gain. A sample of 716,392 births …

Comparative Value Of Echocardiography Vs. Right Heart Catheterization In Heart Failure With Preserved Ejection Fraction, Nathanael Tran, Mohammad Shaar, Hussein Al-Sudani, Ramy Sedhom, Hamza Akhtar, Kevin Bryan Lo, Gregg S. Pressman

Einstein Health Papers

BACKGROUND: Echocardiography and right heart catheterization (RHC) are useful in the evaluation of heart failure with preserved ejection fraction (HFpEF). We compared the two among decompensated HFpEF patients to determine their relative value in predicting all-cause mortality and a composite of cardiovascular (CV) death and heart failure (HF) readmission at 1 year.

METHODS: One hundred seventy-eight decompensated HFpEF patients who underwent both procedures and survived to hospital discharge were retrospectively identified. Hospital records and the National Death Index were queried to determine outcomes. Echocardiographic and invasive parameters were tested for significant associations with each outcome. Additionally, three predictive models were …

Student Papers, Posters & Projects

BACKGROUND: Preeclampsia (PE) is a complex disorder with significant maternal and fetal risks. The soluble fms-like tyrosine kinase-1 (sFlt-1) and placental growth factor (PlGF) ratio shows promise as a diagnostic tool, but its adoption in the U.S. remains limited due to the lack of accessible testing platforms, U.S.-based studies, and evidence-based implementation guidelines.

PATIENTS/MATERIALS AND METHODS: We conducted a cohort study to evaluate the sFlt-1/PlGF ratio for predicting PE within two weeks among pregnant individuals ≥18 years, ≥20 weeks gestation. Serum samples were obtained from routine prenatal visits or triage evaluations. sFlt-1/PlGF ratios were measured using Roche Elecsys assays, and …

Tubulin Regulates Stability And Localization Of Stmn2 By Binding Preferentially To Its Soluble Form, Xiang Deng, Gary A Bradshaw, Marian Kalocsay, Timothy Mitchison

Faculty, Staff and Student Publications

The small, tubulin-binding protein STMN2 is highly expressed in neurons and is implicated in amyotrophic lateral sclerosis. STMN2 degrades rapidly and accumulates at axotomy sites, suggesting fast turnover is crucial for its neuroprotective function. We show that STMN2 was primarily degraded by the ubiquitin-proteasome system. Its membrane-targeting N-terminal domain promoted fast turnover, whereas its tubulin-binding domain promoted stabilization. Proximity labeling and imaging showed that tubulin binding reduced STMN2 targeting to trans-Golgi network membranes. Pull-down assays showed that tubulin binds preferentially to soluble over membrane-bound STMN2. Our observations suggest that STMN2 interconverts between a soluble, tubulin-bound form and a membrane-bound, tubulin-free …

A complication of viral lung infections is the development of pulmonary fibrosis. This phenomenon is most evident in patients with COVID-19, where in its most aggressive form patients developed nonresolvable (NR) COVID-19 requiring lung transplantation. NR-COVID-19 was characterized by the presentation of a fulminant fibrotic lung injury that progressed rapidly, even in patients with limited comorbidities. However, the mechanisms that led to this rapidly progressing form of fibrosis are not fully understood. A common clinical manifestation in the most severe cases of COVID-19 was the presence of "silent" hypoxemia. Thus, we hypothesized that a dysfunctional hypoxic response may result in …

Faculty, Staff and Student Publications

Background: Matrix metalloproteinase 7 (MMP-7) is a novel biomarker for diagnosis of biliary atresia (BA), the most common cholestatic liver disease in infancy. There is a pressing need to determine the utility of MMP-7 levels in infants with congenital heart disease (CHD) to avoid unnecessary invasive diagnostic procedures in this high-risk population. We investigated the utility of MMP-7 in discriminating BA from non-BA cholestasis in infants with CHD and whether MMP-7 elevation was present in infants requiring treatment for clinically significant PH.

Methods: This is a single-center cross-sectional study including infants < 180 days of age with cholestasis and serum MMP-7 levels collected from 2019 to 2023. Demographic data and descriptive statistics were summarized with medians with interquartile ranges and frequencies with percentages. Median MMP-7 levels were assessed via Wilcoxon rank-sum test.

Smart Spatial Omics (S2-Omics) Optimizes Region Of Interest Selection To Capture Molecular Heterogeneity In Diverse Tissues, Musu Yuan, Kaitian Jin, Hanying Yan, Amelia Schroeder, Chunyu Luo, Sicong Yao, Bernhard Dumoulin, Jonathan Levinsohn, Tianhao Luo, Jean R Clemenceau, Inyeop Jang, Minji Kim, Yunhe Liu, Minghua Deng, Emma E Furth, Parker Wilson, Anupma Nayak, Idania Lubo, Luisa Maren Solis Soto, Linghua Wang, Jeong Hwan Park, Katalin Susztak, Tae Hyun Hwang, Mingyao Li

Faculty, Staff and Student Publications

Spatial omics technologies have transformed biomedical research by enabling high-resolution molecular profiling while preserving the native tissue architecture. These advances provide unprecedented insights into tissue structure and function. However, the high cost and time-intensive nature of spatial omics experiments necessitate careful experimental design, particularly in selecting regions of interest (ROIs) from large tissue sections. Currently, ROI selection is performed manually, which introduces subjectivity, inconsistency and a lack of reproducibility. Previous studies have shown strong correlations between spatial molecular patterns and histological features, suggesting that readily available and cost-effective histology images can be leveraged to guide spatial omics experiments. Here we …

The Deubiquitinating Enzyme Cezanne Stabilizes Brca1 By Counteracting Apc/C And Ube2s-Dependent Lys11-Linked Ubiquitination, Longqiang Wang, Xiao Wu, Atanu Paul, Jun Yao, Bin Wang

Faculty, Staff and Student Publications

The breast and ovarian tumor suppressor BRCA1 is a cell cycle-regulated protein and tumors with reduced BRCA1 protein level may share molecular features of BRCA1-mutant tumor and respond to PARPi therapy. Here, we identify that BRCA1 protein stability is controlled through ubiquitin lysine 11 (K11)-linkage modification under the regulation of Cezanne deubiquitinating enzyme, APC/C E3 ligase, and Ube2S E2 conjugating enzyme in a cell cycle-dependent manner. Cezanne-deficiency leads to increased BRCA1 K11-ubiquitination, decreased BRCA1 protein level, and increased cellular sensitivity to PARPi. The BRCA1 K11-linked ubiquitination is carried out through a degron on BRCA1 that is recognized by APC/C cofactor …

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. …

Faculty, Staff and Student Publications

Background: Idecabtagene vicleucel (ide-cel) is a BCMA-directed CAR-T associated with high response rates in relapsed/refractory multiple myeloma (RRMM), yet responses are not durable and most patients experience toxicities. Fludarabine (Flu) is a key component of lymphodepletion but exhibits significant pharmacokinetic (PK) variability.

Objective: Given Flu exposure (AUC) predicts outcomes after CD19-directed CAR-T, we hypothesized it would predict outcomes after ide-cel. Our objective was to determine the association between fludarabine AUC and clinical outcomes after standard-of-care (SOC) ide-cel.

Study design: RRMM patients receiving ide-cel from 10 US Multiple Myeloma Immunotherapy Consortium centers were retrospectively analyzed. A population PK approach using cumulative …
