The ataxia telangiectasia and RAD3-related (ATR) kinase functions with ataxia telangiectasia-mutated (ATM) kinase as a modulator of DNA damage response (DDR). We assessed the antitumor effects of the ATR inhibitor elimusertib (BAY-1895344) in patient-derived xenograft (PDX) models with DDR alterations. Antitumor activity was assessed by change in tumor volume (TV) from baseline. Responses were categorized as follows: partial response (PR), ≥30% decrease in TV; ≥20% increase in TV, progressive disease; and non-PR/progressive disease, stable disease (SD). Event-free survival was defined as time for tumor doubling (EFS-2). Of 21 PDX models tested, 11 had significant prolongation of EFS-2 with elimusertib monotherapy. …

Department of Dermatology and Cutaneous Biology Faculty Papers

The potent sensitizer PPD is considered a key sensitizer in hair dye contact allergy. Modification of its molecular structure to 2-methoxymethyl-p-phenylenediamine (ME-PPD) reduces its skin sensitizing potency. We investigated the usage, behavior, and tolerance profile of ME-PPD-containing professional hair color products in a specifically tailored proactive market surveillance program in hairdresser salons across 5 countries. Hairdressers completed record cards for their clients, which were evaluated at the end of the program. 497 individuals received in total 2461 hair color treatments with ME-PPD-containing hair color. Feedback on compatibility was provided for 194 individuals: 6 individuals reported intolerance reactions, which were assessed …

Psma-1-Dota Potentially For Effective Targeted Radioligand Therapy Of Prostate Cancer, Xinning Wang, Olga Sergeeva, Maxim Sergeev, Lifang Zhang, Zoey Lockwood, Zhenghong Lee, James P. Basilion

Faculty Scholarship

Purpose: While PSMA-targeted radioligand therapy (RLT) has shown remarkable efficacy for treating end-stage prostate cancer, the α-emitting RLT often results in severe salivary gland toxicity, limiting its use. Various strategies to mitigate this side effect have been attempted with limited success. Accordingly, this study introduced a new PSMA-targeting ligand with more favorable binding characteristics than the existing ligands. Procedures: The binding affinity of PSMA-1-DOTA to PSMA was compared with that of PSMA-11 and PSMA I&T. Comparison of uptake in the salivary glands, kidneys and PC3pip tumor cells in the xenograft mouse models between [⁶⁸Ga]Ga-PSMA-1-DOTA, [⁶⁸Ga]Ga-PSMA-11 and [⁶⁸Ga]Ga-PSMA I&T was conducted …

Purpose: To define the genetic architecture of foveal morphology and explore its relevance to foveal hypoplasia (FH), a hallmark of developmental macular disorders.

Methods: We applied deep-learning algorithms to quantify foveal pit depth from central optical coherence tomography (OCT) B-scans in 61,269 UK Biobank participants. A genome-wide association study (GWAS) was conducted using REGENIE, adjusting for age, sex, height, and ancestry. Rare coding variants (frequency < 1%) were analyzed in an exome-wide rare-variant association study (RVAS). Candidate genes were prioritized using integrative mapping; pathway, cross-ancestry, and genetic-correlation analyses were exploratory.

Results: GWAS identified 126 sentinel variants, including 47 novel associations. Integrative mapping prioritized 129 putative causal genes, with 64 not previously implicated in foveal biology. Enriched pathways included retinoic acid metabolism (e.g., CYP26A1), photoreceptor differentiation …

Commensal Colonization Of Candida Albicans In The Mouse Gastrointestinal Tract Is Mediated Via Expression Of Candidalysin And Adhesins, Kelsey E Mauk, Pedro Miramón, Michael C Lorenz, Léa Lortal, Julian R Naglik, Bernhard Hube, Lynn Bimler, Farrah Kheradmand, David B Corry

Faculty, Staff and Students Publications

The ubiquitous fungal pathogen Candida albicans has the potential to either asymptomatically colonize the gastrointestinal (GI) tract or become an invasive pathogen through mechanisms that remain incompletely understood. Here we explored the fungal, host, and environmental factors that influence the ability of C. albicans to colonize the mouse GI tract using a representative clinical strain, CLCA10. After a single gavage challenge (5 × 106 CFU C. albicans), specific pathogen-free (SPF) mice remained colonized with C. albicans strain CLCA10, but not other Candida species, for at least 58 days with the fungus confined largely to the gut luminal …

Encapsulation Of Disease-Causing And Commensal Mitis Group Non-Pneumococcal Streptococci, Daniel M Musher, Mathias Müsken, M John Hicks, Lesley Mcgee, Bernard Beall

Faculty, Staff and Students Publications

Background: Mitis group non-pneumococcal streptococci (MGNPS), specifically Streptococcus mitis, Streptococcus infantis and Streptococcus oralis, have recently been shown to cause pneumonia and/or bacteremia. These organisms often have capsular (cps) operons resembling those in pneumococci, and some express cps-generated polysaccharides that antigenically cross-react with pneumococcal capsular serotypes. But, to date, a series of MGNPS isolates has not been studied by electron microscopy (EM) for the presence of a capsule.

Methods: We studied 21 MGNPS; 11 were isolated from sputum and determined to have caused pneumonia, 3 were isolated from blood, and 7 were commensal isolates cultured …

Premenopausal Transition In Neurodivergent Women With Musculoskeletal Syndromes: Mechanisms, Risks, And Neuroinclusive Therapeutics, Piper Hutson, James Hutson

Faculty Scholarship

Neurodivergent women with chronic musculoskeletal syndromes experience disproportionate premenopausal symptom burdens that are poorly characterized in extant clinical paradigms and practice. The compounded interplay of estrogen fluctuations in premenopause with sensory–executive differences and baseline nociception from joint or connective-tissue pathology yields intensified pain, mood dysregulation, and functional decline. Evidence indicates estrogen modulates nociception, neuroinflammation, bone remodeling, and monoaminergic signaling; premenopausal variability magnifies pain, affective lability, and cognitive drift—effects accentuated in autism and ADHD. Coexisting hypermobility, fibromyalgia, or connective-tissue disorders compromise joint integrity and proprioception, increasing susceptibility to estrogen-dependent changes in bone microarchitecture and tendon homeostasis. This article advances an integrative …

High-Frequency And Conventional Ventilation In Very Low Birth Weight Neonates During Interfacility Transport, Trevor Cabrera, Janelle R. Noel-Macdonnell, Emily Mcnellis

Posters

Background: Very low birth weight (VLBW) neonates (≤1500 grams) transported across neonatal facilities often require advanced respiratory support, including high-frequency ventilation (HFV). While HFV use in this setting has increased, data evaluating its safety and efficacy in the VLBW population remain limited. We hypothesized that HFV will provide a safe modality to transport sick VLBW infants. Objectives: To present a comparative experience of safety and efficacy of HFV and CV in VLBW neonates during interfacility transport. Methods: We retrospectively reviewed neonates ≤1500g who received invasive ventilation during interfacility transport by our transport team between January 2019 and December 2022. HFV …

Discontinuous Or Attenuated Background, Absent Sleep Architecture, Absent Reactivity, And Presence Of Subclinical Seizures On Continuous Electroencephalography Are Associated With Unfavorable Short-Term Outcome Following Pediatric Severe Traumatic Brain Injury​, Xuexin Lu, Ara Hall, Yong Y. Han, Madeline Burdick, Avner Moeded, Isabella Boedefeld, Christian Kaufman, Jessica S. Wallisch

Presentations

BACKGROUND/PURPOSE: Accurate prognostication following pediatric severe traumatic brain injury (sTBI) remains challenging. Adult neuroprognostication guidelines recommend the use of prediction models that have not yet been validated in pediatric patients. We hypothesized certain continuous electroencephalography (cEEG) characteristics would be associated with unfavorable short-term outcome. METHODS: This was an IRB-approved, 7-year retrospective cohort study of children aged 1.5-18 years admitted to our PICU from 01/2018-12/2024 with sTBI and receiving cEEG monitoring per institutional standard management protocol. cEEG patterns (background, sleep architecture, reactivity, and electrographic seizure) during the first 12-hours of monitoring were analyzed for association with unfavorable short-term outcome at PICU …

Severe Thiopurine-Induced Myelosuppression In A Pediatric All Patient With The Nudt15 *1/*6 Genotype, Jillian Fry, Keith August, Terrie Flatt Do, Laura B. Ramsey

Posters

Introduction: Genetic variants in TPMT and NUDT15 that affect the metabolism of mercaptopurine (6MP) are routinely tested for to guide 6MP dosing. Nudix hydroxylase 15 (NUDT15) deficiency can cause myelosuppression when affected patients are treated with 6MP. The NUDT15 *6 allele is classified as having uncertain function by the Clinical Pharmacogenetics Implementation Consortium Guidelines given insufficient data to determine its phenotype. Here, we present the case of a pediatric patient with the NUDT15 *1/*6 genotype experiencing significant mercaptopurine-induced myelosuppression. Case Description: We present a 4-year-old female with standard risk-average precursor B-cell acute lymphoblastic leukemia treated per AALL1731. Exome sequencing reported …

Digital Journal of Clinical Medicine

Background: Cervical cancer remains the fourth most common cancer among women globally and a leading cause of cancer-related mortality in India. Despite being largely preventable through screening, uptake remains suboptimal due to socio-cultural and systemic barriers.

Methods: A community-based cross-sectional study was conducted among 300 women aged ≥20 years residing in urban and rural areas of Mysuru. Data were collected using a pre-tested, semi-structured questionnaire and analyzed with SPSS version 30.

Results: Awareness of cervical cancer was reported by 90% of participants and of screening methods by 80%. However, only 21% had ever undergone screening and 17% within the preceding …

Diagnostic Journey In The Recognition Of Oncogenic Osteomalacia, Steven B. Nagelberg, Mihaela Biscoveanu, Barbara Bix, Carrie Andrews, Srinivas Prasad

Jefferson Health - Northeast Papers (formerly Aria Health Papers)

A 73-year-old woman with a remote history of successfully treated primary hyperparathyroidism was referred to our office because of multiple skeletal fractures and proximal muscle weakness. Prior laboratory evaluation demonstrated hypocalcemia, vitamin D deficiency, elevated PTH, and elevated alkaline phosphatase. Updated evaluation in our clinic additionally showed hypophosphatemia prompting measurement of serum fibroblast growth factor 23 (FGF23). FGF23 proved to be markedly elevated prompting consideration of tumor-induced osteomalacia. Positron emission tomography with Cu-64 oxodotreotide revealed an enhancing focus in the left thoracic spine that was confirmed on magnetic resonance imaging to be a 1.5-cm extradural mass. The patient underwent surgical …

Lumbar Microdiscectomy: A Rare Case Of A Duplicate L5 Exiting Nerve Root., Sahil Garg, Sean M Muir, Arianna K Gill, Komi E Afetse, Sanjitpal S Gill

Surgery Articles

The microdiscectomy procedure has been regarded as the preferred method for the treatment of lumbar disc herniation (LDH). Intraoperatively, the procedure may be further complicated due to underlying anatomical variations in the lumbar spine or nerve root variations. Nerve root anomalies (NRAs), in particular, are relatively underdiscussed within the literature. Despite the rarity of these variations to the exiting nerve root, the increased surgical risk that an NRA may add warrants the need for increased awareness and associated complication mitigation. This case describes a rare instance of a symptomatic duplicate L5 nerve root discovered preoperatively and highlights the steps taken …

Fractures In Parkinson's Disease: Pathophysiology, Prevention, And Orthopedic Outcomes., Ali Osman, Tala Maya, Rayyan Bhutta, Natasha Doshi, Maryam Khan, Sara Shah, Paslene Periceles, Janae Rasmussen

Surgery Articles

Fractures are an important comorbidity in Parkinson's disease (PD), which can result in disability, mortality, and high healthcare costs. Impaired mobility, postural instability, bradykinesia, muscle rigidity, and decreased bone mineral density (BMD) contribute to the increased risk of falls, which often result in hip and upper extremity fractures. Hip fractures in patients with PD are associated with an increased hospital length of stay and a decline in functional independence. Multimodal fall prevention in PD is well established, but prevention of fractures is often underutilized, despite evidence-based interventions. Information on fall-related fracture outcomes after exercise interventions is an area warranting further …

Airway Management In Patients With Vocal Cord Paralysis: A Review Of Intubation Techniques, Intraoperative Challenges, And Outcomes., Rayyan Bhutta, Ali Osman, Tala Maya, Justin Ma, Ali Al Saeed, Sumit Sidhu, Mariya Wood, Bilal Akhtar, Sirimas Lau, Matthias Franzen

Surgery Articles

Vocal cord paralysis (VCP) presents with unique challenges when managing airways, particularly during endotracheal intubation. This literature review explores the effects of unilateral and bilateral VCP on intubation technique, first-pass success, extubation safety, and perioperative airway planning. While video laryngoscopy (VL) is becoming increasingly favored for its superior airway visualization, it does not always confirm successful placement in patients with VCP. Complications such as airway edema, aspiration risk, and cuff misplacements are increased in this patient population, and they may be more vulnerable to post-extubation complications, especially without the use of steroid prophylaxis or intensive post-operative planning. A comparison of …

Malignancy-Associated Renal Infarction: A Case Of Prostate Cancer Presenting With Flank Pain And Hematuria., Connor J Stinson, Alec Pupo, Patrick Laird

Internal Medicine Resident Research

Renal infarction is an uncommon but critical diagnosis that is frequently overlooked due to its nonspecific presentation and overlap with more common causes of abdominal or flank pain. Patients with malignancy, including metastatic prostate cancer, are at increased risk of thromboembolic events due to the intrinsic hypercoagulable state promoted by cancer, yet arterial events, such as renal infarction, remain underrecognized. We present the case of a 74-year-old male with metastatic castrate-sensitive prostate cancer who developed acute abdominal pain, nausea, and vomiting. Evaluation revealed elevated blood pressure, microscopic hematuria, and increased lactate dehydrogenase (LDH). CT scan of the abdomen and pelvis …

Actin Up And Factor’D In: ​ A Pediatric Spindle Cell Lesion Case Presentation, Michael Higham, Stephanie Campbell, Naomie Jean, Amanda Killeen

School of Podiatric Medicine Publications

Introduction: Solitary spindle cell nodules on the foot in pediatric patients are rare and diagnostically challenging. Dermatofibroma (benign fibrous histiocytoma), a common adult dermal lesion, is infrequently observed in children under 18.

The spectrum of pediatric spindle cell tumors includes reactive entities like nodular fasciitis and dermatomyofibroma, benign neoplasms such as myofibroma, and malignant tumors including spindle cell rhabdomyosarcoma, fibrosarcoma, and dermatofibrosarcoma protuberans (DFSP). Accurate differential diagnosis is essential, as DFSP requires wide excision or Mohs surgery to reduce recurrence risk.

Methods (Case Presentation): An 11-year-old boy presented with a one-year history of a non-healing lesion on the heel, initially …

A Novel “Stairstep” Approach To The Management Of Extreme Hypernatremia Using Continuous Kidney Replacement Therapy And Hypertonic Saline, Bahar Barani, Xuexin Lu, Darcy Weidemann, Judith Vansickle, Vimal Chadha, Nathan Beins

Posters

Hypernatremia is defined as a serum sodium greater than 145 mEq/L and is due to either a deficit of free water or excess sodium intake. Extreme hypernatremia (sodium level > 190 mEq/L) is immediately life–threatening with mortality rates > 60%. It is especially challenging to avoid complications, such as permanent neurological injury, respiratory failure, and profound electrolyte derangement, when children are in kidney failure. Established guidelines are lacking for correcting such extreme levels due to a paucity of information in the literature, although general recommendations are to decrease levels by no more than 10-12 mEq/L per day to prevent neurological complications. We …

Recombinant Erythropoietin Use For Anemia Of Prematurity: A Three Year Since Center Experience, Hannah Darland, Krishna Dummula, Chaitali Mahajan, Vishal Pandey

Posters

Background: Anemia is a common disorder of prematurity secondary to limited blood volume, excessive blood draws, inadequate nutrition, poor iron reserves, and insufficient endogenous erythropoietin. While many NICUs use recombinant erythropoietin (rEpo) to treat anemia of prematurity, the absence of universal guidelines has led to variability in dosing and schedules. Here we present our experience on the use of rEpo in a level 3 NICU. Our unit protocol uses 400 IU/kg three times a week for a total of 9 doses if hematocrit < 30%. Objectives: The purpose of this study was to evaluate the response to rEpo in infants with anemia of prematurity. Methods: Charts of infants born between 2018 and 2020 with gestation ≤34 weeks who received rEpo for anemia of prematurity were retrospectively reviewed. We defined response to therapy as an increase of hematocrit by 5% from pre-treatment baseline. Infants who did not achieve the therapeutic goal or who received blood transfusions were considered non-responders. Neutropenia, thrombocytopenia, and retinopathy of prematurity (ROP) requiring treatment were treated as adverse events. Results: A total of 44 infants were treated with rEpo during the study period. Clinical characteristics are described in Table I. Average hematocrit at birth was 44.8±7.5 (32.7 to 60.8). Infants were started on rEPO at a median corrected age of 33.3 ±3 weeks and a weight of 1674±622 g. Average DOL was 37±18 at initiation of therapy. Average baseline hematocrit at the start of therapy was 27.9±1.8%. 80% of patients (35/44) responded with increase of hematocrit by >5%, 20% (9/44) did not respond. 75% of infants (33/44) received all 9 doses. 11 patients received …
