Sorting Through Life: Evaluating Patient-Important Measures Of Success In A Medication For Opioid Use Disorder (Moud) Treatment Program, Megan K Reed, Kelsey R Smith, Francesca Ciocco, Richard W. Hass, Avery Lin Cox, Erin L Kelly, Lara Weinstein

Department of Emergency Medicine Faculty Papers

Background: Medication for opioid use disorder (MOUD) is the gold standard treatment for opioid use disorder. Traditionally, "success" in MOUD treatment is measured in terms of program retention, adherence to MOUD, and abstinence from opioid and other drug use. While clinically meaningful, these metrics may overlook other aspects of the lives of people with opioid use disorder (OUD) and surprisingly do not reflect the diagnostic criteria for OUD.

Methods: Authors identified items for a pilesorting task to identify participant-driven measures of MOUD treatment success through semi-structured interviews. Interviews were transcribed verbatim and coded in Nvivo using directed and conventional content …

How The Rural Risk Environment Underpins Hepatitis C Risk: Qualitative Findings From Rural Southern Illinois, United States, Suzan M Walters, David Frank, Marisa Felsher, Jessica Jaiswal, Scott Fletcher, Alex S Bennett, Samuel R Friedman, Lawrence J Ouellet, Danielle C Ompad, Wiley Jenkins, Mai T Pho

College of Population Health Faculty Papers

Background: Hepatitis C virus (HCV) infection has increased among persons who inject drugs (PWID) in the United States with disproportionate burden in rural areas. We use the Risk Environment framework to explore potential economic, physical, social, and political determinants of hepatitis C in rural southern Illinois.

Closed-Loop Modeling Of Central And Intrinsic Cardiac Nervous System Circuits Underlying Cardiovascular Control, Michelle M. Gee, Abraham M. Lenhoff, James S. Schwaber, Babatunde A. Ogunnaike, Rajanikanth Vadigepalli

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

The baroreflex is a multi-input, multi-output physiological control system that regulates blood pressure by modulating nerve activity between the brainstem and the heart. Existing computational models of the baroreflex do not explicitly incorporate the intrinsic cardiac nervous system (ICN), which mediates central control of heart function. We developed a computational model of closed-loop cardiovascular control by integrating a network representation of the ICN within central control reflex circuits. We examined central and local contributions to the control of heart rate, ventricular functions, and respiratory sinus arrhythmia (RSA). Our simulations match the experimentally observed relationship between RSA and lung tidal volume. …

Mendelian Randomization Analysis Reveals A Complex Genetic Interplay Among Atopic Dermatitis, Asthma, And Gastroesophageal Reflux Disease, Kwangmi Ahn, Raymond B. Penn, Satish Rattan, Reynold A. Panettieri, Benjamin F. Voight, Steven S. An

Division of Gastroenterology and Hepatology Faculty Papers

RATIONALE: Gastroesophageal reflux disease (GERD) is commonly associated with atopic disorders, but cause-effect relationships remain unclear.

OBJECTIVES: We applied Mendelian randomization (MR) analysis to explore whether GERD is causally related to atopic disorders of the lung (asthma) and/or skin (atopic dermatitis).

METHODS: We conducted two-sample bidirectional MR to infer the magnitude and direction of causality between asthma and GERD, using summary statistics from the largest genome-wide association studies (GWAS) conducted on asthma (N_cases=56,167) and GERD (N_cases=71,522). Additionally, we generated instrumental variables (IVs) for atopic dermatitis (AD) from the latest population-level GWAS meta-analysis (N_cases=22,474) and …

Seifert, Michio Hirano, Martin Picard

Department of Pediatrics Faculty Papers

Patients with primary mitochondrial oxidative phosphorylation (OxPhos) defects present with fatigue and multi-system disorders, are often lean, and die prematurely, but the mechanistic basis for this clinical picture remains unclear. By integrating data from 17 cohorts of patients with mitochondrial diseases (n = 690) we find evidence that these disorders increase resting energy expenditure, a state termed hypermetabolism. We examine this phenomenon longitudinally in patient-derived fibroblasts from multiple donors. Genetically or pharmacologically disrupting OxPhos approximately doubles cellular energy expenditure. This cell-autonomous state of hypermetabolism occurs despite near-normal OxPhos coupling efficiency, excluding uncoupling as a general mechanism. Instead, hypermetabolism is associated …

Alcoholic Vs. Nonalcoholic Steatohepatitis: Vascular Branching Heterogeneity On Magnetic Resonance Imaging As A Diagnostic Marker, Daniel Garrido, Nicholas Noverati, Justin Robbins, Jaydev K. Dave, Haresh V. Naringrekar, Donald Mitchell, Dina Halegoua-De Marzio

Division of Gastroenterology and Hepatology Faculty Papers

Background and aims: Distinguishing alcoholic steatohepatitis (ASH) and nonalcoholic steatohepatitis (NASH) with biopsy alone is often difficult without a reliable clinical context. A novel finding on liver imaging, perivascular branching heterogeneity, has shown promise in distinguishing between these chronic liver diseases. Our study investigated the role of this finding on imaging to differentiate between ASH and NASH. The aim of this study was to determine the utility and reproducibility of this novel radiographic marker to help distinguish ASH from NASH.

Methods: This was a retrospective cohort study conducted between 2016 and 2020 in patients with both liver biopsy-confirmed steatohepatitis/chronic hepatitis …

Dance/Movement Therapy As A Holistic Approach To Diminish Health Discrepancies And Promote Wellness For People With Schizophrenia: A Review Of The Literature, Jacelyn Biondo

Department of Family & Community Medicine Faculty Papers

Individuals with a diagnosis of schizophrenia face a myriad of obstacles to wellness, beginning with diagnostic discrepancies including over- and misdiagnoses on the schizophrenia spectrum. People with schizophrenia experience profound amounts of stigmatization from the general population, their healthcare providers, and even themselves. Such stigmatization creates a barrier for wellness, poorer prognoses, and often limits adherence to physical and mental healthcare. Moreover, it can exacerbate the already stifling symptomatology of their diagnoses, including specific bodily-related symptomatology. Oftentimes, a diagnosis of schizophrenia disrupts one's relationship with their body including a diminished mind-body connection, decreased interoceptive awareness, and thus unsuccessful intra- and …

Identification Of Collaborative Cross Mouse Strains Permissive To Salmonella Enterica Serovar Typhi Infection, Kishore Alugupalli, Sudeep Kothari, Matthew P Cravens, Justin A Walker, Darren T Dougharty, Gregory S. Dickinson, Louis A Gatto, Andreas J Bäumler, Tamding Wangdi, Darla R Miller, Fernando Pardo-Manuel De Villena, Linda D Siracusa

Department of Microbiology and Immunology Faculty Papers

Salmonella enterica serovar Typhi is the causative agent of typhoid fever restricted to humans and does not replicate in commonly used inbred mice. Genetic variation in humans is far greater and more complex than that in a single inbred strain of mice. The Collaborative Cross (CC) is a large panel of recombinant inbred strains which has a wider range of genetic diversity than laboratory inbred mouse strains. We found that the CC003/Unc and CC053/Unc strains are permissive to intraperitoneal but not oral route of S. Typhi infection and show histopathological changes characteristic of human typhoid. These CC strains are immunocompetent, …

Wills Eye Hospital Papers

Background: During the treatment of age-related macular degeneration with anti-vascular endothelial growth factor (VEGF) drugs, we often see cases with anti-VEGF-resistant refractory subretinal fluid. In this report, we present two cases of anti-VEGF-resistant refractory age-related macular degeneration (AMD) due to the concurrent development of central serous chorioretinopathy (CSCR) in eyes previously well controlled with intravitreal anti-VEGF injections. Case presentation: Two patients underwent intravitreal aflibercept for the treatment of neovascular AMD. Initially, both patients responded well to intravitreal aflibercept, resulting in the complete resolution of the subretinal fluid. However, both patients subsequently developed sudden-onset refractory subretinal fluid that did not respond …

Center for Translational Medicine Faculty Papers

Background: Successful embryo implantation requires the attachment of a blastocyst to the receptive endometrial epithelium, which was disturbed in the women with recurrent implantation failure (RIF). Endometrial β3-integrin was the most important adhesion molecule contributing to endometrial receptivity in both humans and mice. Nur77 has been proven indispensable for fertility in mice, here we explore the role of Nur77 on embryo-epithelial adhesion and potential treatment to embryo implantation failure.

Methods: The expression and location of Mst1 and Nur77 in endometrium from fertile women and RIF patients were examined by IHC, qRT-PCR and Western blotting. In vitro kinase assay following with …

Graph Theoretical Measures Of Fast Ripple Networks Improve The Accuracy Of Post-Operative Seizure Outcome Prediction, Shennan A Weiss, Itzhak Fried, Chengyuan Wu, Ashwini Sharan, Daniel Y. Rubinstein, Jerome Engel, Michael R Sperling, Richard J Staba

Department of Neurosurgery Faculty Papers

Fast ripples (FR) are a biomarker of epileptogenic brain, but when larger portions of FR generating regions are resected seizure freedom is not always achieved. To evaluate and improve the diagnostic accuracy of FR resection for predicting seizure freedom we compared the FR resection ratio (RR) with FR network graph theoretical measures. In 23 patients FR were semi-automatically detected and quantified in stereo EEG recordings during sleep. MRI normalization and co-registration localized contacts and relation to resection margins. The number of FR, and graph theoretical measures, which were spatial (i.e., FR rate-distance radius) or temporal correlational (i.e., FR mutual information), …

Disruption Of The Interaction Between Mutationally Activated Gαq And Gβγ Attenuates Aberrant Signaling, Jenna L Aumiller, Philip B Wedegaertner

Department of Biochemistry and Molecular Biology Faculty Papers

Heterotrimeric G protein stimulation via G protein-coupled receptors promotes downstream proliferative signaling. Mutations can occur in Gα proteins which prevent GTP hydrolysis; this allows the G proteins to signal independently of G protein-coupled receptors and can result in various cancers, such as uveal melanoma (UM). Most UM cases harbor Q209L, Q209P, or R183C mutations in Gαq/11 proteins, rendering the proteins constitutively active (CA). Although it is generally thought that active, GTP-bound Gα subunits are dissociated from and signal independently of Gβγ, accumulating evidence indicates that some CA Gα mutants, such as Gαq/11, retain binding to Gβγ, and this interaction is …

An Entosis-Like Process Induces Mitotic Disruption In Pals1 Microcephaly Pathogenesis, Noelle A Sterling, Jun Young Park, Raehee Park, Seo-Hee Cho, Seonhee Kim

Center for Translational Medicine Faculty Papers

Entosis is cell cannibalism utilized by tumor cells to engulf live neighboring cells for pro- or anti-tumorigenic purposes. It is unknown whether this extraordinary cellular event can be pathogenic in other diseases such as microcephaly, a condition characterized by a smaller than normal brain at birth. We find that mice mutant for the human microcephaly-causing gene Pals1, which exhibit diminished cortices due to massive cell death, also exhibit nuclei enveloped by plasma membranes inside of dividing cells. These cell-in-cell (CIC) structures represent a dynamic process accompanied by lengthened mitosis and cytokinesis abnormalities. As shown in tumor cells, ROCK inhibition completely …

Differentiating Pc12 Cells To Evaluate Neurite Densities Through Live-Cell Imaging, Jordyn Karliner, Diane E Merry

Department of Biochemistry and Molecular Biology Faculty Papers

Although PC12 cells are a valuable tool in neuroscience research, previously published PC12 cell differentiation techniques fail to consider the variability in differentiation rates between different PC12 cell strains and clonal variants. Here, we present a comprehensive protocol to differentiate PC12 cells into equivalent neurite densities through live-cell imaging for morphological, immunocytochemical, and biochemical analyses. We detail steps on optimized substrate coating, plating techniques, culture media, validation steps, and quantification techniques.

Robotically Assisted Mitral Valve Repair—Port-Only Totally Endoscopic Approach, Kellen J. Round, Colin C. Yost, Jake L. Rosen, Jenna L. Mandel, Meagan Wu, Luke C. Olson, Jordan E. Goldhammer, T. Sloane Guy

Department of Surgery Faculty Papers

Robotic mitral valve repair (MVR) is an emerging option to treat degenerative valve disease. Compared to open thoracotomy, robotic mitral valve surgery has been shown to afford decreased postoperative length of stay with comparable rates of mortality and morbidity. Among the variety of techniques for robotic MVR, the totally endoscopic approach remains the least invasive method to date. In this report, we describe our technique for totally endoscopic robotically-assisted MVR. In particular, we seek to highlight the use of several unique techniques in MVR. Percutaneous cannulation with use of the endoballoon is employed for cardiopulmonary bypass (CPB), thus avoiding traditional …
