Ischemic Stroke As The Initial Presentation Of Advanced Pancreatic Adenocarcinoma: A Case Of Marantic Endocarditis., Micah Harris

Ambulatory and Primary Care Articles

Nonbacterial thrombotic endocarditis (NBTE), formerly known as marantic endocarditis, is a rare condition characterized by sterile vegetations on cardiac valves and is often associated with hypercoagulable states such as adenocarcinoma. We describe a patient who presented with multiple embolic cerebrovascular accidents, ultimately found to be secondary to NBTE, which served as the initial manifestation of previously undiagnosed advanced pancreatic adenocarcinoma. This case underscores the importance of considering NBTE in patients with multifocal embolic infarcts, particularly when blood cultures are negative, echocardiography reveals valvular abnormalities without evidence of infection, and clinical suspicion for an underlying malignancy is present.

2020-Current year OA Pubs

OBJECTIVES: Pivotal trials have established the effectiveness of the Responsive Neurostimulation System (RNS® System) in treating focal epilepsy. In clinical trials, depth leads were primarily used to treat mesial temporal seizure onsets while cortical strip leads were used to treat neocortical seizure onsets. Here, we systematically analyze the safety and efficacy of stereoelectroencephalography (sEEG)-guided depth leads to provide responsive stimulation to neocortical gray matter.

METHODS: Patients were stratified as strong responders (>median cohort seizure reduction %), weak responders (>0% and ≤median cohort seizure reduction %), and anti-responders (≤0%) based on percent seizure reduction at 1 year post-implant (1-Y). …

Loss Of Beta-Cell Identity And Function As A Mechanism Of Secondary Failure Of Sulfonylurea Therapy In Diabetes, Sumit Patel, Zihan Yan, Maria S Remedi

2020-Current year OA Pubs

Sulfonylureas, commonly used to treat type 2 diabetes (T2D), often lose effectiveness over time when used as monotherapy; however, the underlying mechanisms remain unclear. To investigate the mechanisms of sulfonylurea failure, glibenclamide-releasing pellets were implanted in KK mice, a polygenic model that spontaneously develops T2D. KK mice receiving placebo pellets (KK-Placebo) developed hyperglycemia, hyperinsulinemia, glucose intolerance, and insulin resistance. Notably, KK mice implanted with glibenclamide (KK-Glib) showed improved blood glucose levels during the first 7 days, returning to KK-Placebo levels thereafter. KK-Glib mice exhibited reduced plasma insulin levels and insulin secretion in response to a glucose challenge compared with the …

Faculty, Staff and Student Publications

Human fatty acid binding protein‐4 (FABP‐4), a protein elevated in obesity that promotes colon cancer cell invasiveness and metastasis, may be associated with higher mortality in individuals with colorectal cancer (CRC) and may serve as a mediator of the obesity–mortality association in these individuals. We used a causal diagram to inform covariate selection and applied Cox proportional hazards models to estimate hazard ratios (HRs) for CRC‐specific, non‐CRC‐specific, and all‐cause mortality by FABP‐4 levels measured in baseline blood samples from 1371 incident CRC cases from the European Prospective Investigation into Cancer and Nutrition cohort. Competing risk analyses were adapted for CRC …

Silent Messengers In The Nano-World: Harnessing Extracellular Vesicles As Theranostic Tools For Neonatal Surgical Conditions, Augusto Zani

2020-Current year OA Pubs

Extracellular vesicles (EVs) are lipid bilayer-enclosed nanoparticles secreted by all cells that mediate intercellular communication by transferring proteins, lipids, and nucleic acids. Among their cargo, microRNAs are key post-transcriptional regulators of organogenesis. In fetal lung development, EV-mediated signaling is essential for the coordination of epithelial, mesenchymal, endothelial, and immune cells. In congenital diaphragmatic hernia (CDH), disruption of these interactions leads to pulmonary hypoplasia and pulmonary hypertension, the primary causes of morbidity and mortality. Amniotic fluid stem cell-derived EVs (AFSC-EVs) have emerged as a promising cell-free therapy to restore this impaired communication. In rodent, rabbit, and human models of pulmonary hypoplasia, …

Effects Of Dual-Eligible Integrated Care Plans On Medicaid Enrollment And Retention: Evidence From The Implementation Of Medicare-Medicaid Plans, Eric T Roberts, Eliza Macneal, Kenton J Johnston, José F Figueroa

2020-Current year OA Pubs

Medicare and Medicaid are separate programs that together cover 13 million low-income older adults and people with disabilities, known as dual-eligible individuals. Concern about a lack of coordination across Medicare and Medicaid has prompted the development of Integrated Care Programs (ICPs). Although the primary goal of ICPs is to coordinate financing and care across Medicare and Medicaid, ICPs may also influence whether low-income individuals obtain or keep Medicaid. We evaluated whether the rollout of Medicare-Medicaid Plans (MMPs)-one of the largest ICPs-was associated with changes in Medicaid take-up and retention among Medicare beneficiaries residing in high-poverty zip codes. Using a stacked …

Peak Lower Limb Joint Angles Are Weak Predictors Of Hamstring Length Change During Sprinting, Shayne Vial, Jodie Cochrane Wilkie, Anthony J. Blazevich, Daniel Kadlec

Research outputs 2022 to 2026

Non-contact hamstring injuries (HSIs) commonly occur during the late swing phase of sprinting, when muscle–tendon units (MTUs) approach maximum length. Although sagittal-plane pelvis, hip and knee angles are often used as surrogate measures of overall hamstring lengthening, their predictive validity remains uncertain. This study investigated whether peak three-dimensional lower limb joint angles predict length change in the biarticular hamstring MTUs from peak hip flexion through to toe off (0–100 %) in fourteen intermediate-level male soccer players sprinting at maximal speed (8.56 ± 0.47 m·s−1). Participant-specific musculoskeletal models were used to compute MTU lengths for the biceps femoris long head (BFlh), …

Mckay, Nicolin Tee, Megan L. Ross, Stacey N. Reinke, John A. Hawley, David Broadhurst, Louise M. Burke

Research outputs 2022 to 2026

Periods of low energy availability (LEA) are common in elite athletes and typically arise from reduced energy intake, often involving some degree of carbohydrate (CHO) restriction. Whether the metabolic profile created by energy restriction per se is distinct compared to that driven by CHO restriction is unknown. Using untargeted metabolomics, we examined metabolic perturbations linked to CHO restriction and energy restriction in plasma from elite male endurance athletes. In a semi-randomized controlled trial, athletes (n = 20) completed one of three 5-day dietary interventions: high energy-high CHO (HCHO); LEA (energy-restricted, CHO-reduced); or low-CHO, high-fat (LCHF; energy-matched, CHO-restricted). Plasma samples were …
