Sleep-Wake Variation In Body Temperature Regulates Tau Secretion And Correlates With Csf And Plasma Tau, Geoffrey Canet, Brendan P. Lucey, Et Al. Feb 2025

Sleep-Wake Variation In Body Temperature Regulates Tau Secretion And Correlates With Csf And Plasma Tau, Geoffrey Canet, Brendan P. Lucey, Et Al.

2020-Current year OA Pubs

Sleep disturbance is bidirectionally associated with an increased risk of Alzheimer's disease and other tauopathies. While the sleep-wake cycle regulates interstitial and cerebrospinal fluid (CSF) tau levels, the underlying mechanisms remain unknown. Understanding these mechanisms is crucial, given the evidence that tau pathology spreads through neuron-to-neuron transfer, involving the secretion and internalization of pathological tau forms. Here, we combined in vitro, in vivo, and clinical methods to reveal a pathway by which changes in body temperature (BT) over the sleep-wake cycle modulate extracellular tau levels. In mice, a higher BT during wakefulness and sleep deprivation increased CSF and plasma tau …

Retinoic Acid Antagonizes Estrogen Signaling To Maintain Adult Uterine Cell Fate, Yan Yin, Meade Haller, Lauren Goldinger, Shivani Bharadwaj, Emily So, Vivian Robles-Pinos, David Chen, Liang Ma

2020-Current year OA Pubs

Classical tissue recombination experiments demonstrate that cell-fate determination along the anterior-posterior axis of the Müllerian duct occurs prior to postnatal day 7 in mice. However, little is known about how these cell types are maintained in adults. In this study, we provide genetic evidence that a balance between antagonistic retinoic acid (RA) and estrogen signaling activity is required to maintain simple columnar cell fate in adult uterine epithelium. Transdifferentiation of simple columnar uterine epithelium into stratified cervicovaginal-like epithelium was observed in three related mouse genetic models, in which RA signaling was perturbed in the postnatal uterus. Single-cell RNA sequencing analysis …

Mobile Clinic Effects On A Rural Emergency Department, Jonathan Levenson, John S. Hudson Feb 2025

Mobile Clinic Effects On A Rural Emergency Department, Jonathan Levenson, John S. Hudson

Graduate Student Government Association Research Conference

PROBLEM: Emergency department (ED) utilization is a measure the effectiveness of the department and an indication of the availability of primary care in the community. The ED of a given healthcare system can be overwhelmed with patients seeking both urgent and non-urgent care, especially in rural and underserved communities. Non-urgent care accounts for over a half of all visits in most EDs. Much of this non-urgent care in the ED is caused by several socioeconomic factors including access to care around working schedules, no requirement for payment when services are rendered, and a lack of a primary care provider. Mobile …

Csd Students Of Color Navigating The Graduate School Admissions Process: A Gauntlet, Marcella Cardoza Mccollum

Teaching and Learning in Communication Sciences & Disorders

Regardless of entry point, nearly all potential speech-language pathologists (SLPs) in the United States (US) share the experience of navigating the arduous application process for graduate school. For students of color, especially first-generation students, this application process can serve to cause them to question whether they belong in the field. This may be one of the key factors that manifests itself in the lack of diversity within the profession. This study followed nine undergraduate Communication Sciences and Disorders (CSD) students across nine months from application cycle through post-baccalaureate life as they shared their experiences about deciding whether to apply for …

Despite the established efficacy of heart failure (HF) guideline-directed medical therapies, implementation varies across demographic groups, including Black, Indigenous, and people of color, older adults, females, and those who are socioeconomically deprived. This review synthesizes the representativeness of trial participants and describes subgroup analyses from pivotal trials in HF with reduced ejection fraction (HFrEF). It reviews the largely consistent treatment effect of medical therapies across the demographic groups represented in trials. It makes arguments for broad implementation of therapies based on these data, while calling for more representative trials to improve research and health equity in HF.

Screening And Treatment Of Iron Deficiency Among Heart Failure Patients With Impaired Ejection Fraction: The Impact Of A Pharmacist-Led Protocol, Firas Al Badarin, Feras Bader, Bassam Atallah

Faculty Scholarship

Background: Despite guideline-recommended routine screening and iron deficiency (ID) treatment among heart failure (HF) patients, these practices are often underutilized. Currently, limited data are available on the outcomes of pharmacists' programs to enhance ID screening and management. Accordingly, we sought to describe the frequency and yield of screening for ID and intravenous (IV) iron replacement rates among our cohort of HF patients and examined the impact of implementing a pharmacist-led protocol (PLP) aimed at enhancing these rates. Methods: We conducted a retrospective study involving HF patients with left ventricular ejection fraction (LVEF) <45% at a quaternary care hospital in the Middle East/Gulf region. The PLP was introduced in August 2022. Data on demographics, comorbidities, echocardiographic parameters, laboratory findings (including ID screening and its findings), and rates of treatment with IV iron replacement were analyzed and compared between the pre-implementation group (n = 432, October 2015–February 2020) and the post-implementation group (n = 154, August 2022–January 2023). Results: Before the PLP, 63.2% (n = 273) of eligible patients underwent ID screening, with 80.6% (n = 220) found to have ID. Following the implementation of the PLP, screening rates significantly increased to 86.4% (n = 133) (p = 0.03), with 53.4% (n = 71) diagnosed with ID. The rate of IV iron replacement in ID patients improved from 30.4% (n = 67) in the pre-PLP group to 73% (n = 52) in the post-PLP group (p < 0.001). Multivariable logistic regression identified baseline glomerular filtration rate (GFR) and hemoglobin levels as significant predictors of IV iron replacement in the pre-PLP cohort. Conclusions: Implementing a pharmacist-led protocol was significantly associated with enhancing the screening and treatment of ID in patients with HF and LVEF <45%. This study demonstrates the crucial role of pharmacists in optimizing guideline-directed therapies, which can be replicated in various healthcare settings.

Faculty, Staff and Students Publications

Brain arteriovenous malformations are abnormal vascular structures in which an artery shunts high pressure blood directly to a vein without an intervening capillary bed. These lesions become highly remodeled over time and are prone to rupture. Historically, brain arteriovenous malformations have been challenging to treat, using primarily surgical approaches. Over the past few decades, the genetic causes of these malformations have been uncovered. These can be divided into (1) familial forms, such as loss of function mutations in TGF-β (BMP9/10) components in hereditary hemorrhagic telangiectasia, or (2) sporadic forms, resulting from somatic gain of function mutations in genes involved in …

Posterior interosseous nerve (PIN) syndrome refers to a rare compressive neuropathy of the PIN resulting in motor dysfunction of the forearm extensor compartment. Often, surgical exploration will reveal extrinsic structures that mechanically compress the nerve. Less frequently, PIN syndrome has been reported with a visible hourglass-like constriction and no identifiable causative adjacent structures. In our report, we describe an adolescent patient with PIN syndrome and associated hourglass-like constriction of the PIN. For diagnosis, we used physical examination, preoperative imaging, nerve studies, and intraoperative findings. To monitor recovery, we performed serial neurological examinations and documented patient-reported functional outcomes. The patient underwent …

Dominant mutations in the calcium-permeable ion channel TRPV4 (transient receptor potential vanilloid 4) cause diverse and largely distinct channelopathies, including inherited forms of neuromuscular disease, skeletal dysplasias and arthropathy. Pathogenic TRPV4 mutations cause gain of ion channel function and toxicity that can be rescued by small molecule TRPV4 antagonists in cellular and animal models, suggesting that TRPV4 antagonism could be therapeutic for patients. Numerous variants in TRPV4 have been detected with targeted and whole exome/genome sequencing, but for the vast majority, their pathogenicity remains unclear. Here, we used a combination of clinical information and experimental structure-function analyses to evaluate 30 …

Department of Emergency Medicine Faculty Papers

BACKGROUND: The early assessment of heart failure (HF) risk in patients with acute coronary syndrome (ACS) can help reduce mortality. S100A8/A9 is not only rapidly released after myocardial ischemia, but is also involved in reperfusion injury, which is an important predictor of HF after ACS. We attempted to construct a reliable HF risk stratification tool for evaluating patients with ACS after reperfusion therapy based on S100A8/A9 dynamic changes.

METHODS AND RESULTS: This prospective study included 3 independent cohorts of patients with ACS who received reperfusion therapy. The discovery cohort was divided into 2 subgroups: the longitudinal subgroup (n=264) with serum …

School of Medicine Faculty Publications

The adrenal medulla is packed with chromaffin cells, modified postganglionic sympathetic neurons that secrete the catecholamines, epinephrine and norepinephrine, during the fight-or-flight response. Sometimes overlooked is a population of immune cells that also resides within the gland but whose distribution and function are not clear. Here I examine the location of CD45+ hematopoietic cells in the mouse adrenal medulla and show the majority are F4/80+/Lyz2+ macrophages. These cells are present from early postnatal development and widely distributed. Anatomically they are associated with chromaffin cells, found aligned alongside synapsin-IR neuronal varicosities and juxtaposed to CD31-IR blood vessels. Using Lyz2cre-GCaMP6f mice to …

Background: Cancer creates an immunosuppressive environment that hampers immune responses, allowing tumors to grow and resist therapy. One way the immune system fights back is by inducing ferroptosis, a type of cell death, in tumor cells through CD8 + T cells. This involves lipid peroxidation and enzymes like lysophosphatidylcholine acyltransferase 3 (Lpcat3), which makes cells more prone to ferroptosis. However, the mechanisms by which cancer cells avoid immunotherapy-mediated ferroptosis are unclear. Our study reveals how cancer cells evade ferroptosis and anti-tumor immunity through the upregulation of fatty acid-binding protein 7 (Fabp7).

Methods: To explore how cancer cells resist immune cell-mediated …
