Background: Wilson’s disease is a rare genetic disorder characterized by copper accumulation, leading to multi-organ symptoms. It affects between 1 in 30,000 to 1 in 100,000 individuals, with a mean age at diagnosis of 13.2 years. The diagnosis may be overlooked due to its numerous presentations, which can range from non-specific symptoms such as fever, fatigue, and behavioral changes to fulminant hepatic failure. Its clinical manifestations vary widely, making diagnosis during pregnancy particularly challenging. Wilson’s disease complicates pregnancy, as untreated cases can lead to significant morbidity and mortality; excess copper can disrupt metabolic processes and contribute to recurrent miscarriages.

Pumping Iron, Straining Hearts: Androgen Building Cardiomyopathy In A Middle Aged Bodybuilding Enthusiast, Milan Terzic, Yash B. Patel

Graduate Medical Education Research Journal

A 46-year-old bodybuilder presenting with new onset dyspnea found to have a new onset non-ischemic cardiomyopathy (CM) attributed to exogenous trenbolone and testosterone use. Steroid cessation and guideline-directed heart failure therapy led to notable recovery in left ventricular function supported by global longitudinal strain, ejection fraction and symptomatology.

Anabolic steroid-induced CM involves multiple mechanisms including lipid disturbances, hypertrophy, reduced receptor sensitivity, and cell damage. This case emphasizes the importance of recognizing anabolic steroid misuse as a potential cause of non-ischemic cardiomyopathy in middle aged men. With prompt discontinuation of steroids, remained abstinence and early initiation of guideline-directed medical therapy, myocardial …

Transcriptomic Profile Analysis Of Brain Tissue In The Absence Of Functional Trpm8 Calcium Channel, Erick B Saldes, Alexandra Erdmier, Jai Velpula, Timothy E Koeltzow, Michael X Zhu, Swapna Asuthkar

Faculty, Staff and Student Publications

Background/Objectives: Transient Receptor Potential Melastatin 8 (TRPM8) is a non-selective, Ca2+-permeable cation channel involved in thermoregulation and other physiological processes, such as basal tear secretion, cell differentiation, and insulin homeostasis. The activation and deactivation of TRPM8 occur through genetic modifications, channel interactions, and signaling cascades. Recent evidence suggests a significant role of TRPM8 in the hypothalamus and amygdala related to pain sensation and sexual behavior. Notably, TRPM8 has been implicated in neuropathic pain, migraines, and neurodegenerative diseases such as Parkinson's disease. Our laboratory has identified testosterone as a high-affinity ligand of TRPM8. TRPM8 deficiency appears to influence behavioral traits in …

Faculty, Staff and Student Publications

The primary cilium is a cellular antenna to orchestrate cell growth and differentiation. Deficient or dysfunctional cilia are frequently linked to skeletal abnormalities. Previous research demonstrated that ciliary proteins regulating axoneme elongation are essential for skeletogenesis. However, the role of the ciliary proteins responsible for initiating cilium assembly in skeletal development remains unknown. Here, we investigate the function of centrosomal protein of 164 kDa (CEP164), a key ciliogenesis regulator that localizes at the distal appendages of the mother centriole, during skeletal development in mice. Interestingly, the mesodermal cell-specific Cep164 deletion resulted in severe bone defects and osteoblast-specific deletion of Cep164 …

A Bayesian Pharmacokinetics Integrated Phase I-Ii Design To Optimize Dose-Schedule Regimes, Mengyi Lu, Ying Yuan, Suyu Liu

Faculty, Staff and Student Publications

The schedule of administering a drug has profound impact on the toxicity and efficacy profiles of the drug through changing its pharmacokinetics (PK). PK is an innate and indispensable component of the dose-schedule optimization. Motivated by this, we propose a Bayesian PK integrated dose-schedule finding (PKIDS) design to identify the optimal dose-schedule regime by integrating PK, toxicity, and efficacy data. Based on the causal pathway that dose and schedule affect PK, which in turn affects efficacy and toxicity, we jointly model the three endpoints by first specifying a Bayesian hierarchical model for the marginal distribution of the longitudinal dose-concentration process. …

Predicting Kidney Graft Function And Failure Among Kidney Transplant Recipients, Yi Yao, Brad C Astor, Wei Yang, Tom Greene, Liang Li

Faculty, Staff and Student Publications

Background: Graft loss is a major health concern for kidney transplant (KTx) recipients. It is of clinical interest to develop a prognostic model for both graft function, quantified by estimated glomerular filtration rate (eGFR), and the risk of graft failure. Additionally, the model should be dynamic in the sense that it adapts to accumulating longitudinal information, including time-varying at-risk population, predictor-outcome association, and clinical history. Finally, the model should also properly account for the competing risk by death with a functioning graft. A model with the features above is not yet available in the literature and is the focus of …
