Animal Models Of Aortic Aneurysm And Dissection: A Comparative Guide For Mechanism, Therapeutic Testing, And Translational Readouts, Shayan Mohammadmoradi, Sidney W. Whiteheart

Saha Cardiovascular Research Center Faculty Publications

Aortic aneurysms and dissections are devastating vascular diseases with high mortality, yet no pharmacological therapy has proven effective in halting growth or preventing rupture. Surgical and endovascular repair remain the only treatment options for advanced disease. Animal models have been indispensable in defining mechanisms and testing candidate therapies, but the diversity of protocols, strain-dependent variability, and heterogeneous endpoints complicate interpretation and translation. This review provides an update focused on how to match models to specific research questions. We critically compare commonly used abdominal aortic aneurysm (AAA) models (angiotensin II ± hyperlipidemia, elastase, calcium chloride, β-aminopropionitrile BAPN hybrids, and mineralocorticoid agonist/fludrocortisone …

Differences In Biologic Clinical Trials For Chronic Rhinosinusitis With Nasal Polyps—Are We Comparing Apples With Oranges?, Marjolein Cornet, Peter W. Hellings, Martin Desrosiers, Martin Wagenmann, Richard Follows, Laura Walrave, Luz Adriana Jimenez, Lee Tombs, Dawn Edwards, Peter Howarth, Joseph K. Han

Department of Otolaryngology (ENT) Faculty Publications

In recent years, several biologics targeting Type 2 inflammation have been developed for treating chronic rhinosinusitis with nasal polyps (CRSwNP). These have been studied in registrational randomized controlled trials (RCTs), which vary in their patient populations, trial design, endpoints, geography, timing, or data-handling processes. While (in)direct treatment comparisons and meta-analyses have been carried out to compare efficacy results from RCTs, often these fail to properly account for these between-study differences. Here, we summarize the key between-study differences that can influence trial outcomes and highlight the resulting challenges faced when comparing outcomes from different Phase III RCTs of biologics in CRSwNP.

Neuron-Enriched Extracellular Vesicle Micrornas Reflect Hormonal Suppression Associated With Oral Contraceptive Use In Young Women, Amulya Chowdhory, Rebekah Frye, Roxann Roberson-Nay

Undergraduate Research Posters

Hormonal contraceptives alter hypothalamic–pituitary–ovarian (HPO) feedback, but their impact on brain-associated molecular communication remains poorly understood. Neuron- enriched extracellular vesicle (nEV) microRNAs (miRNAs), isolated from plasma, provide a minimally invasive window into brain molecular activity. This pilot study examined nEV miRNA expression in young women (ages 18–22) who were either naturally cycling or using a combined monophasic oral contraceptive (OC) pill. To identify hormonally responsive miRNAs, we calculated effect sizes (Cohen’s d) between the two groups and selected those showing large between-group differences (|d| ≥ 0.8). These miRNAs were entered into a principal component analysis (PCA) to reduce dimensionality, and …

Neurosurgery Faculty Publications

Background: Degenerative cervical myelopathy (DCM) is caused by chronic compression of the cervical spinal cord. Individuals usually present with a combination of upper extremity dysfunction, imbalance, and bladder dysfunction, which impact overall quality of life. Various questionnaires like mJOA, Nurick, NDI, and DCM-72 have been used for disease stratification. Our study aims to evaluate the clinical correlation between self-reported measures and objective upper extremity assessments and to derive the minimal clinically important difference (MCID) for individuals with DCM.

Methods: A prospective two-center study of consecutive patients diagnosed with DCM was undertaken. A comprehensive assessment of upper extremity functioning including dexterity, …

Orthopaedic Surgery Faculty Publications

Background: Many orthopaedic trials use any unplanned reoperation as the primary outcome, but this overlooks how patients experience those outcomes. Using a high-quality hip fracture trial, we demonstrate how the relative importance of multiple patient-important outcomes can be effectively incorporated into data analysis, providing a more comprehensive understanding of treatment impact. Methods: This secondary analysis of the Fixation using Alternative Implants for the Treatment of Hip Fracture (FAITH) trial included 1,079 patients aged 50 years or older with a low-energy femoral neck fracture who were randomly assigned to treatment with a sliding hip screw or cancellous screws. The original trial …

Leveraging Virtual Reality And Haptics To Teach Surgical Skills: A Usability Study On Retropubic Midurethral Slings, Lauren Siff, Ginger S. Watson, Jerome Dixon, Moshe Feldman, Franklin Bost, Philippe J. Giabbanelli

VMASC Publications

Traditional methods to learn soft-tissue surgical procedures rely on cadaver labs or patient-based learning, which are costly and geographically limited, and raise ethical questions. Virtual reality (VR) with haptic feedback offers a scalable alternative, but most current platforms emphasize bone-based rather than soft-tissue procedures learned by feel. We developed a VR+haptic simulation for preoperative training of retropubic midurethral sling (MUS) surgery. This study examines the usability of this platform with thirteen expert urogynecologic surgeons and subsequently makes improvements (e.g., in haptics) to evaluate the platform with twelve trainees based on the NASA Task Load Index for workload and a UTAUT-informed …

VMASC Publications

Coarctation of the aorta (CoA) alters hemodynamics and drives regional remodeling, yet the influence of severity and duration on constitutive properties is undefined. We quantified mechanical responses from CoA to identify constitutive parameters capturing stiffening across clinical severities and durations. Mild (≤ 12 mmHg), intermediate (13–20 mmHg), and severe (> 20 mmHg) CoA was created in rabbits for short, long, and prolonged durations (~ 1, 3, or 22 weeks, respectively). Stress–stretch curves from proximal and distal regions were fit with multiple constitutive models (Linear Elastic, Neo-Hookean, Yeoh, Ogden, Mooney–Rivlin, Holzapfel). Model performance was evaluated by normalized RMSE and R², with …

Machine Learning Classification Of Prostate Cancer Genomic Sequences Using K-Mer And Sequence-Derived Features, Kuldeep Rawat, Hirendra Nath Banerjee, Jamie Noble, Saa Naudia Deloatch, Satyendra Banerjee, Sachin Shetty, Soumya Banerjee

VMASC Publications

Prostate cancer disproportionately impacts African American men, who experience significantly higher mortality rates and earlier disease onset than other populations. Current diagnostic approaches, including prostate-specific antigen testing and biopsy, lack sufficient specificity and sensitivity, underscoring the need for accurate, molecular-level classification tools. This paper presents a machine learning framework for binary classification of genomic DNA sequences as cancerous or healthy. A dataset of 1684 FASTA-formatted sequences obtained from the National Library of Medicine - GenBank was analyzed, with 1662 sequences retained after quality control filtering. Feature engineering yielded 67 attributes, including GC content, Shannon entropy, sequence length, and trinucleotide k-mer …

Early Detection In Oral Cancer: Are We Prepared For Artificial Intelligence-Driven Precision Medicine?, Nikil Kumar, Sinnha Kumari, Sadia Sultana, Muhammad Saad Khan, Tirath Patel, Nikhilesh Anand

School of Medicine Publications

Oral cancer, particularly oral squamous cell carcinoma, remains a serious health concern, with a poor prognosis and a late diagnosis. Leukoplakia, erythroplakia, lichen planus, and submucous fibrosis are examples of oral potentially malignant disorders that must be detected early but are not always so by traditional, laborious, and subjective diagnostic techniques. In oral cancer, artificial intelligence (AI) and precision medicine are becoming game-changing technologies that enhance individualized care, treatment planning, and diagnostic precision. Complex imaging and histopathology data may be analyzed using machine learning and deep learning algorithms, particularly convolutional neural networks, which can identify patterns that are invisible to …

Application Of Current Enteral Nutrition Support Recommendations To Infants Born Less Than 750 Grams Or Less Than 25 Weeks' Gestation: A Critical Review, Mar Romero-Lopez, Mamta Naik, Teresa Hartman, Ann Anderson-Berry, Melissa Thoene

Journal Articles: Pediatrics

Clinicians face a paucity of evidence-based recommendations for provision of enteral nutrition in infants born < 750 g or < 25 weeks' gestation, termed "nano-preterm." Current enteral nutrition recommendations for extremely low birth weight infants may not be broadly applicable to nano-preterm infants due to physiological and developmental differences, while others may be appropriate. Key enteral nutrition-related considerations include: the unique anatomy and physiology of the gastrointestinal tract, altered metabolic capacity, availability of maternal milk and use of alternative substrates, detailed methods of initiation and advancement of enteral feeding, methods of human milk fortification, targeted requirements for macronutrient and micronutrients, and the safety and efficacy of enteral nutrition support management to optimize the growth and development of the nano-preterm infant. This comprehensive review focused on enteral nutrition provision in nano-preterm infants, thoroughly evaluating available literature and identifying knowledge gaps about the unique physiology and metabolism of the nano-preterm infant as it pertains to enteral nutrition. Ultimately, prospective multicenter research is needed to establish evidence-based guidelines to promote optimal growth and development while minimizing complications of extreme prematurity.

Robust Lc–Ms/Ms Method For Quantification Of Ascorbic Acid In Infant Formula And Heat-Processed Donor Human Milk: A Stabilization And Matrix Effects Mitigation Approach, Omar M. Al Kilani, Lee C. Winchester, Melissa Thoene, Colman Freel, Christopher Lee Shaffer, Anthony T. Podany

Journal Articles: Pediatrics

Ascorbic acid is an essential antioxidant for infant health; however, its quantification in infant formula and human milk is challenging due to matrix complexity, analyte instability, and lack of blank matrix equivalents. This study presents a simple and robust LC-MS/MS method that bypasses the need for standard addition using only 20 µL sample. The method showed excellent linearity (R² > 0.99), precision (CV < 15%), accuracy (±10%), and sensitivity (LOD < 0.0375 µg/mL). Stock and working solutions remained stable for months at −20 and −80 °C, respectively, avoiding daily preparation. Optimized extraction substantially reduced matrix effects. The method was externally validated using certified infant formula reference material and successfully applied to commercial samples, with incurred sample reanalysis showing <  20% variation. This validated method offers a practical tool for the routine quantification of ascorbic acid in heat-processed donor human milk and infant formula, with the potential for application to other matrices.

Nutritional Management At 22-23 Weeks Gestational Age: Evidence And Knowledge Gaps, Mar Romero-Lopez, Mamta Naik, Melissa Thoene, Ann Anderson-Berry

Journal Articles: Pediatrics

With advancing medical capabilities, survival of infants born at 22-23 weeks' gestation is increasing. However, specific recommendations for nutrition support for these infants are lacking. This review examines the unique characteristics of infants born at 22-23 weeks' gestation that impact parenteral and enteral nutrition support, highlighting the lack of evidence and knowledge gaps for optimal practices. Current recommendations developed for extremely or very low birth weight infants may be unsuitable for infants born at 22-23 weeks' gestation due to important differences in anatomy, physiology, body composition, and metabolic capabilities. Key challenges include severely limited intraluminal digestion, profound immune and microbiome …

We performed this systematic review and meta-analysis to assess the efficacy and safety of anticoagulation therapy versus no anticoagulation in pediatric patients with cerebral sinovenous thrombosis (CSVT). Eligible studies included pediatric patients with CSVT that compared anticoagulation to no anticoagulation and reported on at least one relevant outcome (mortality, neurological deficit, thrombus resolution, recurrence, and bleeding). Meta-analysis reported risk ratios (RR) or differences (RD) (95% CIs) and absolute effects per 1000 patients. Risk of bias was assessed using ROBINS-I, and the certainty of evidence was evaluated with GRADE. After removing duplicates, we screened 8925 records independently and in duplicate, from …

The Impact Of Gastric Sleeve And Roux-En-Y Gastric Bypass On Chief Cell Function And Protein Digestion In Obese Patients, Garikoitz Mikel Gainza

Honors Undergraduate Theses

Obesity has become one of the largest global health concerns of the 21^st century, correlating with numerous associated diseases. To help address the growing prevalence and burden of obesity, sleeve gastrectomy and Roux-en-Y gastric bypass have become two commonly performed surgical procedures done to promote weight loss by altering the anatomical structure of the stomach and surrounding organs of the gastrointestinal system. Although the benefits of improved metabolism linked to these surgical procedures are well studied, their impact on the physiology of gastric cells, and more specifically chief cells as they relate to protein digestion post-surgery, is yet to …
