Evaluation Of Multi-Level Barriers And Facilitators In A Large Diabetic Retinopathy Screening Program In Federally Qualified Health Centers: A Qualitative Study, Ana Bastos De Carvalho, S. Lee Ware, Tamara Belcher, Franceska Mehmeti, Eric B. Higgins, Robert Sprang, Cody Williams, Jamie L. Studts, Christina R. Studts

Ophthalmology and Visual Science Faculty Publications

BACKGROUND: Recommended annual diabetic retinopathy (DR) screening for people with diabetes has low rates in the USA, especially in underserved populations. Telemedicine DR screening (TDRS) in primary care clinics could expand access and increase adherence. Despite this potential, studies have observed high variability in TDRS rates among clinics and over time, highlighting the need for implementation supports. Previous studies of determinants of TDRS focus on patients' perspectives, with few studies targeting upstream multi-level barriers and facilitators. Addressing this gap, this qualitative study aimed to identify and evaluate multi-level perceived determinants of TDRS in Federally Qualified Health Centers (FQHCs), to inform …

Inflammatory Regulation Of Cns Barriers After Traumatic Brain Injury: A Tale Directed By Interleukin-1, Colleen N. Bodnar, James B. Watson, Emma K. Higgins, Ning Quan, Adam D. Bachstetter

Neuroscience Faculty Publications

Several barriers separate the central nervous system (CNS) from the rest of the body. These barriers are essential for regulating the movement of fluid, ions, molecules, and immune cells into and out of the brain parenchyma. Each CNS barrier is unique and highly dynamic. Endothelial cells, epithelial cells, pericytes, astrocytes, and other cellular constituents each have intricate functions that are essential to sustain the brain’s health. Along with damaging neurons, a traumatic brain injury (TBI) also directly insults the CNS barrier-forming cells. Disruption to the barriers first occurs by physical damage to the cells, called the primary injury. Subsequently, during …

Johnson Jr., Helen Liu, Joann Sorra, Jane Brock, Brianna Gass, Jing Li, Jessica Miller Clouser, Karen Hirschman, Deborah Carpenter, Huong Q. Nguyen, Mark V. Williams

Center for Health Services Research Faculty Publications

Background
The quality of the discharge process and effective care transitions between settings of care are critical to minimize gaps in patient care and reduce hospital readmissions. Few studies have explored which care transition components and strategies are most valuable to patients and providers. This study describes the development, pilot testing, and psychometric analysis of surveys designed to gain providers’ perspectives on current practices in delivering transitional care services.

Methods
We underwent a comprehensive process to develop items measuring unique aspects of care transitions from the perspectives of the three types of providers (downstream, ambulatory, and hospital providers). The process …

Operative Management Of Symptomatic, Metachronous Carotid Body Tumors Involving The Skull Base And Its Neurological Sequelae, Roberto G. Aru, Rony K. Aouad, Justin F. Fraser, Amanda M. Romesberg, Kevin W. Hatton, Sam C. Tyagi

Otolaryngology--Head & Neck Surgery Faculty Publications

A 44-year-old morbidly obese woman with a history of right carotid body tumor (CBT) resection presented with a symptomatic, nonfunctional, left Shamblin-III CBT. Abutment of the skull base precluded distal internal carotid artery control for arterial reconstruction, favoring parent vessel sacrifice after an asymptomatic provocative test. She underwent CBT resection with anticipated sacrifice of cranial nerves X and XII and the common carotid artery and its branches, developing baroreceptor failure syndrome and sequelae of cranial nerve sacrifice. When facing a symptomatic, metachronous CBT abutting the skull base, upfront operative intervention with adjuvant radiation for residual tumor optimizes curative resection.

Igf1-Stimulated Posttraumatic Hippocampal Remodeling Is Not Dependent On Mtor, Erica L. Littlejohn, Anthony J. Desana, Hannah C. Williams, Rudy T. Chapman, Binoy Joseph, Jelena A. Juras, Kathryn E. Saatman

Physiology Faculty Publications

Adult hippocampal neurogenesis is stimulated acutely following traumatic brain injury (TBI). However, many hippocampal neurons born after injury develop abnormally and the number that survive long-term is debated. In experimental TBI, insulin-like growth factor-1 (IGF1) promotes hippocampal neuronal differentiation, improves immature neuron dendritic arbor morphology, increases long-term survival of neurons born after TBI, and improves cognitive function. One potential downstream mediator of the neurogenic effects of IGF1 is mammalian target of rapamycin (mTOR), which regulates proliferation as well as axonal and dendritic growth in the CNS. Excessive mTOR activation is posited to contribute to aberrant plasticity related to posttraumatic epilepsy, …

Can An Amino Acid Mixture Alleviate Gastrointestinal Symptoms In Neuroendocrine Tumor Patients?, Aman Chauhan, Satya Das, Rachel Miller, Laura Luque, Samuel N. Cheuvront, James Cloud, Zach Tarter, Fariha Siddiqui, Robert A. Ramirez, Lowell B. Anthony

Internal Medicine Faculty Publications

Background: Neuroendocrine tumors, although relatively rare in incidence, are now the second most prevalent gastrointestinal neoplasm owing to indolent disease biology. A small but significant sub-group of neuroendocrine tumor patients suffer from diarrhea. This is usually secondary to carcinoid syndrome but can also be a result of short gut syndrome, bile acid excess or iatrogenic etiologies. Recently, an amino acid based oral rehydration solution (enterade® Advanced Oncology Formula) was found to have anti-diarrheal properties in preclinical models.

Methods: A retrospective chart review of all NET patients treated with enterade® AO was performed after IRB approval.

Results: Ninety-eight NET patients who …

Pi3k/Mtor Dual Inhibitor Pf-04691502 Is A Schedule-Dependent Radiosensitizer For Gastroenteropancreatic Neuroendocrine Tumors, Zeta Chow, Jeremy Johnson, Aman Chauhan, Tadahide Izumi, Michael Cavnar, Heidi L. Weiss, Courtney M. Townsend Jr., Lowell B. Anthony, Carrigan Wasilchenko, Matthew L. Melton, Jörg Schrader, B. Mark Evers, Piotr G. Rychahou

Markey Cancer Center Faculty Publications

Patients with advanced-stage gastroenteropancreatic neuroendocrine tumors (GEP-NETs) have a poor overall prognosis despite chemotherapy and radiotherapy (e.g., peptide receptor radionuclide therapy (PRRT)). Better treatment options are needed to improve disease regression and patient survival. The purpose of this study was to examine a new treatment strategy by combining PI3K/mTOR dual inhibition and radiotherapy. First, we assessed the efficacy of two PI3K/mTOR dual inhibitors, PF-04691502 and PKI-402, to inhibit pAkt and increase apoptosis in NET cell lines (BON and QGP-1) and patient-derived tumor spheroids as single agents or combined with radiotherapy (XRT). Treatment with PF-04691502 decreased pAkt (Ser473) expression for up …

Health, Behavior & Society Faculty Publications

Introduction

Although military veterans are at increased risk for skin cancer, little is known about the extent to which they have been screened for skin cancer. The study objective was to examine the prevalence and correlates of physician skin cancer screening among U.S. military veterans.

Methods

Data were drawn from the National Health Interview Survey. The study sample consisted of 2,826 individuals who reported being military veterans. Receipt of a physician skin examination was measured using a single question that asked participants whether they had ever had all of their skin from head to toe checked for cancer by a …

The Moth-Eaten Mandible: Osteomyelitis, Galal Omami

Oral Health Practice Faculty Publications

Inflammatory lesions such as osteomyelitis of the jaw may share some of the radiographic features of malignancy; however, a demonstrable dental cause for it usually exists. In addition, inflammatory lesions generally stimulate a sclerotic bone reaction, which is uncommon in malignancy. The imaging modality of choice for aiding in the differential diagnosis is computed tomography imaging because of its ability to clearly delineate sequestra and periosteal new bone formation.

A Metabolomic Endotype Of Bioenergetic Dysfunction Predicts Mortality In Critically Ill Patients With Acute Respiratory Failure, Raymond J. Langley, Marie E. Migaud, Lori Flores, J.

Internal Medicine Faculty Publications

Acute respiratory failure (ARF) requiring mechanical ventilation, a complicating factor in sepsis and other disorders, is associated with high morbidity and mortality. Despite its severity and prevalence, treatment options are limited. In light of accumulating evidence that mitochondrial abnormalities are common in ARF, here we applied broad spectrum quantitative and semiquantitative metabolomic analyses of serum from ARF patients to detect bioenergetic dysfunction and determine its association with survival. Plasma samples from surviving and non-surviving patients (N = 15/group) were taken at day 1 and day 3 after admission to the medical intensive care unit and, in survivors, at hospital discharge. …

Identification Of Binding Regions Of Bilirubin In The Ligand-Binding Pocket Of The Peroxisome Proliferator-Activated Receptor-A (Pparalpha), Darren M. Gordon, Stephen H. Hong, Zachary A. Kipp, Terry D. Hinds Jr.

Pharmacology and Nutritional Sciences Faculty Publications

Recent work has shown that bilirubin has a hormonal function by binding to the peroxisome proliferator-activated receptor-α (PPARα), a nuclear receptor that drives the transcription of genes to control adiposity. Our previous in silico work predicted three potential amino acids that bilirubin may interact with by hydrogen bonding in the PPARα ligand-binding domain (LBD), which could be responsible for the ligand-induced function. To further reveal the amino acids that bilirubin interacts with in the PPARα LBD, we harnessed bilirubin’s known fluorescent properties when bound to proteins such as albumin. Our work here revealed that bilirubin interacts with threonine 283 (T283) …
