Quantifying the genetic correlation between cancers can provide important insights into the mechanisms driving cancer etiology. Using genome-wide association study summary statistics across six cancer types based on a total of 296,215 cases and 301,319 controls of European ancestry, here we estimate the pair-wise genetic correlations between breast, colorectal, head/neck, lung, ovary and prostate cancer, and between cancers and 38 other diseases. We observed statistically significant genetic correlations between lung and head/neck cancer (r

Biosynthetic And Synthetic Strategies For Assembling Capuramycin-Type Antituberculosis Antibiotics, Ashley L. Biecker, Xiaodong Liu, Jon S. Thorson, Zhaoyong Yang, Steven G. Van Lanen

Pharmaceutical Sciences Faculty Publications

Mycobacterium tuberculosis (Mtb) has recently surpassed HIV/AIDS as the leading cause of death by a single infectious agent. The standard therapeutic regimen against tuberculosis (TB) remains a long, expensive process involving a multidrug regimen, and the prominence of multidrug-resistant (MDR), extensively drug-resistant (XDR), and totally drug-resistant (TDR) strains continues to impede treatment success. An underexplored class of natural products—the capuramycin-type nucleoside antibiotics—have been shown to have potent anti-TB activity by inhibiting bacterial translocase I, a ubiquitous and essential enzyme that functions in peptidoglycan biosynthesis. The present review discusses current literature concerning the biosynthesis and chemical synthesis of capuramycin …

Evaluating The Efficacy Of Seattle-Pap For The Respiratory Support Of Premature Neonates: Study Protocol For A Randomized Controlled Trial., Carl H Backes, Jennifer L Notestine, Jane M Lamp, Jeanne C Balough, Allison M Notestine, Crystal M Alfred, Juli M Kern, Michael R Stenger, Brian K Rivera, Mohannad Moallem, Randy R Miller, Apurwa Naik, Jennifer N Cooper, Christopher R Howard, Stephen E Welty, Noah H Hillman, John A F Zupancic, Larissa I Stanberry, Thomas N Hansen, Charles V Smith

OhioHealth Research Institute Articles

BACKGROUND: At birth, the majority of neonates born at < 30 weeks of gestation require respiratory support to facilitate transition and ensure adequate gas exchange. Although the optimal approach to the initial respiratory management is uncertain, the American Academy of Pediatrics endorses noninvasive respiratory support with nasal continuous positive airway pressure (nCPAP) for premature neonates with respiratory insufficiency. Despite evidence for its use, nCPAP failure, requiring intubation and mechanical ventilation, is common. Recently, investigators have described a novel method to deliver bubble nCPAP, termed Seattle-PAP. While preclinical and pilot studies are encouraging regarding the potential value of Seattle-PAP, a large trial is needed to compare Seattle-PAP directly with the current standard of care for bubble nCPAP (Fisher & Paykel CPAP or FP-CPAP).

METHODS/DESIGN: We designed a multicenter, non-blinded, randomized controlled trial that will enroll 230 premature infants (22

DISCUSSION: This trial will assess whether Seattle-PAP is more efficacious and cost-effective than FP-CPAP in real-world practice among premature neonates.

We piloted PrEP@Home, a preexposure prophylaxis system of remote laboratory and behavioral monitoring designed to replace routine quarterly follow-up visits with home care to reduce the patient and provider burden. The system was highly acceptable and in-demand for future use, and more than one-third of participants reported greater likelihood of persisting in care if available.

Cancer Screening For Transgender Patients: An Online Case-Based Module, Devin Oller

Internal Medicine Faculty Publications

Introduction: Guidelines recommend that primary care providers complete organ-based routine cancer screening for all transgender patients. Training on critical transgender health topics like cancer screening, as well as residents' confidence in addressing issues their transgender patients may face, remains limited among graduate medical education (GME) programs. Online case-based modules are an effective tool for skills improvement in GME, but their application to transgender health topics has not been assessed.

Methods: I developed a brief online module on cancer screening for transgender patients using Google Forms and offered it to first-year internal medicine residents. The module was optional and asynchronous with …

Sustainability Of Public Health Interventions: Where Are The Gaps?, David Roger Walugembe, Shannon Sibbald, Marlene Janzen Le Ber, Anita Kothari

Health Studies Publications

The current scholarly focus on implementation science is meant to ensure that public health interventions are effectively embedded in their settings. Part of this conversation includes understanding how to support the sustainability of beneficial interventions so that limited resources are maximised, long-term public health outcomes are realised, community support is not lost, and ethical research standards are maintained. However, the concept of sustainability is confusing because of variations in terminology and a lack of agreed upon measurement frameworks, as well as methodological challenges. This commentary explores the challenges around the sustainability of public health interventions, with particular attention to definitions …

Recessively inherited variants in AARS2 (NM_020745.2) encoding mitochondrial alanyl-tRNA synthetase (mt-AlaRS) were first described in patients presenting with fatal infantile cardiomyopathy and multiple oxidative phosphorylation defects. To date, all described patients with AARS2-related fatal infantile cardiomyopathy are united by either a homozygous or compound heterozygous c.1774C>T (p.Arg592Trp) missense founder mutation that is absent in patients with other AARS2-related phenotypes. We describe the clinical, biochemical and molecular investigations of two unrelated boys presenting with fatal infantile cardiomyopathy, lactic acidosis and respiratory failure. Oxidative histochemistry showed cytochrome c oxidase-deficient fibres in skeletal and cardiac muscle. Biochemical studies showed markedly decreased activities …

Developing A Biased Unmatched Bivalent Ligand (Bumbl) Design Strategy To Target The Gpcr Homodimer Allosteric Signaling (Camp Over Β-Arrestin 2 Recruitment) Within The Melanocortin Receptors., Cody J Lensing, Katie T Freeman, Sathya M Schnell, Robert Charles Speth, Adam T Zarth, Carrie Haskell-Luevano

Faculty Articles

Understanding the functional relevance of G protein-coupled receptor (GPCR) homodimerization has been limited by the insufficient tools to assess asymmetric signaling occurring within dimers comprised of the same receptor type. We present unmatched bivalent ligands (UmBLs) to study the asymmetric function of melanocortin homodimers. UmBLs contain one agonist and one antagonist pharmacophore designed to target a melanocortin homodimer such that one receptor is occupied by an agonist and the other receptor by an antagonist pharmacophore. First-in-class biased UmBLs (BUmBLs) targeting the human melanocortin-4 receptor (hMC4R) were discovered. The BUmBLs displayed biased agonism by potently stimulating cAMP signaling (EC

Csf Inflammatory Markers Differ In Gram-Positive Versus Gram-Negative Shunt Infections., Gwenn L. Skar, David C. Synhorst, Matthew Beaver, Jessica N. Snowden

Manuscripts, Articles, Book Chapters and Other Papers

Background: Cerebrospinal fluid (CSF) shunt placement is frequently complicated by bacterial infection. Shunt infection diagnosis relies on bacterial culture of CSF which can often produce false-negative results. Negative cultures present a conundrum for physicians as they are left to rely on other CSF indices, which can be unremarkable. New methods are needed to swiftly and accurately diagnose shunt infections. CSF chemokines and cytokines may prove useful as diagnostic biomarkers. The objective of this study was to evaluate the potential of systemic and CSF biomarkers for identification of CSF shunt infection.

Methods: We conducted a retrospective chart review of children with …

Star-Related Lipid Transfer Protein 10 (Stard10): A Novel Key Player In Alcohol-Induced Breast Cancer Progression, Andrea Floris, Jia Luo, Jacqueline A. Frank, Jennifer Zhou, Sandro Orrù, Michela Biancolella, Sabina Pucci, Augusto Orlandi, Paolo Campagna, Antonella Balzano, Komal Ramani, Maria Lauda Tomasi

Pharmacology and Nutritional Sciences Faculty Publications

Background: Ethanol abuse promotes breast cancer development, metastasis and recurrence stimulating mammary tumorigenesis by mechanisms that remain unclear. Normally, 35% of breast cancer is Erb-B2 Receptor Tyrosine Kinase 2 (ERBB2)-positive that predisposes to poor prognosis and relapse, while ethanol drinking leads to invasion of their ERBB2 positive cells triggering the phosphorylation status of mitogen-activated protein kinase. StAR-related lipid transfer protein 10 (STARD10) is a lipid transporter of phosphatidylcholine (PC) and phosphatidylethanolamine (PE); changes on membrane composition of PC and PE occur before the morphological tumorigenic events. Interestingly, STARD10 has been described to be highly expressed in 35–40% of ERBB2-positive breast …

Reward Improves Response Inhibition By Enhancing Attentional Capture, Yanqing Wang, Todd S Braver, Shouhang Yin, Xueping Hu, Xiangpeng Wang, Antao Chen

2010-2019 OA Pubs

Reward plays a crucial role in enhancing response inhibition. While it is generally assumed that the process of response inhibition involves attentional capture and the stopping of action, it is unclear whether this reflects a direct impact of reward on response inhibition or rather an indirect mediation via attentional capture. Here, we employed a revised stop-signal task (SST) that separated these two cognitive elements, by including a continue signal that required the same motor response as in go trials, but also attention to a cue, as in stop trials. We first confirmed the engagement of the right inferior frontal gyrus …

Consequences Of Pathogen Lists: Why Some Diseases May Continue To Plague Us, David Brett-Major, Trina Racine, Gary P. Kobinger

Journal Articles: Epidemiology

The current strategy used by many funding agencies for determining how money is spent on research to help prevent infectious disease outbreaks is based on pathogen-specific priority lists. Listing disease threats provides focus for business and research planning conducive to specific goals of developing a drug, or a vaccine, or other particular product. But, this singular type of focus has consequences. This perspective explores the consequences of lists, and describes how parallel programming independent of disease lists that address what we need to do to prevent and mitigate emerging disease risks may provide benefits out of reach of a singular …

Journal Articles: Epidemiology

BACKGROUND: Rural residents are less likely to receive screening for colorectal cancer (CRC) than urban residents. However, the mechanisms underlying this disparity, especially among people aged 50-64 years old with private health insurance, are not well understood. We examined the impact of travel time on stage at CRC diagnosis.

METHODS: This retrospective cohort study used data from the Blue Cross and Blue Shield of Nebraska. Members of this private insurance company aged 50-64 years, diagnosed with CRC during the period 2012-2016, and continuously enrolled in the insurance plan for at least 6 months prior to CRC diagnosis, were selected for …

Antibodies In The Diagnosis, Prognosis, And Prediction Of Psychotic Disorders., Thomas A Pollak, Jonathan P Rogers, Robert G Nagele, Mark Peakman, James M Stone, Anthony S David, Philip Mcguire

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Blood-based biomarker discovery for psychotic disorders has yet to impact upon routine clinical practice. In physical disorders antibodies have established roles as diagnostic, prognostic and predictive (theranostic) biomarkers, particularly in disorders thought to have a substantial autoimmune or infective aetiology. Two approaches to antibody biomarker identification are distinguished: a "top-down" approach, in which antibodies to specific antigens are sought based on the known function of the antigen and its putative role in the disorder, and emerging "bottom-up" or "omics" approaches that are agnostic as to the significance of any one antigen, using high-throughput arrays to identify distinctive components of the …

It's More Than Low Bmi: Prevalence Of Cachexia And Associated Mortality In Copd, Merry-Lynn N. Mcdonald, Emiel F.M. Wouters, Erica Rutten, Richard Casaburi, Stephen I. Rennard, David A. Lomas, Marcas Bamman, Bartolome Celli, Alvar Agusti, Ruth Tal-Singer, Craig P. Hersh, Mark Dransfield, Edwin K. Silverman

Journal Articles: Pulmonary & Critical Care Med

BACKGROUND: Cachexia is associated with increased mortality risk among chronic obstructive pulmonary disease (COPD) patients. However, low body mass index (BMI) as opposed to cachexia is often used, particularly when calculating the BODE (BMI, Obstruction, Dyspnea and Exercise) index. For this reason, we examined mortality using a consensus definition and a weight-loss definition of cachexia among COPD cases and compared two new COPD severity indices with BODE.

METHODS: In the current report, the consensus definition for cachexia incorporated weight-loss > 5% in 12-months or low BMI in addition to 3/5 of decreased muscle strength, fatigue, anorexia, low FFMI and inflammation. The …

Linked Mri Signatures Of The Brain's Acute And Persistent Response To Concussion In Female Varsity Rugby Players., Kathryn Y Manning, Alberto Llera, Gregory A Dekaban, Robert Bartha, Christy Barreira, Arthur Brown, Lisa Fischer, Tatiana Jevremovic, Kevin Blackney, Timothy J Doherty, Douglas D Fraser, Jeff Holmes, Christian F Beckmann, Ravi S Menon

Paediatrics Publications

Acute brain changes are expected after concussion, yet there is growing evidence of persistent abnormalities well beyond clinical recovery and clearance to return to play. Multiparametric MRI is a powerful approach to non-invasively study structure-function relationships in the brain, however it remains challenging to interpret the complex and heterogeneous cascade of brain changes that manifest after concussion. Emerging conjunctive, data-driven analysis approaches like linked independent component analysis can integrate structural and functional imaging data to produce linked components that describe the shared inter-subject variance across images. These linked components not only offer the potential of a more comprehensive understanding of …

White Matter Biomarkers Associated With Motor Change In Individuals With Stroke: A Continuous Theta Burst Stimulation Study, K P Wadden, Sue Peters, M R Borich, J L Neva, K S Hayward, C S Mang, N J Snow, K E Brown, T S Woodward, S K Meehan, L A Boyd

Physical Therapy Publications

Continuous theta burst stimulation (cTBS) is a form of noninvasive repetitive brain stimulation that, when delivered over the contralesional hemisphere, can influence the excitability of the ipsilesional hemisphere in individuals with stroke. cTBS applied prior to skilled motor practice interventions may augment motor learning; however, there is a high degree of variability in individual response to this intervention. The main objective of the present study was to assess white matter biomarkers of response to cTBS paired with skilled motor practice in individuals with chronic stroke. We tested the effects of stimulation of the contralesional hemisphere at the site of the …

Hyperpolarized 3he Mri Ventilatory Apparent Diffusion Coefficient Of Alpha-1 Antitrypsin, Andrew Westcott, Dante P I Capaldi, Alexei Ouriadov, David G Mccormack, Grace Parraga

Medical Biophysics Publications

Alpha-1 antitrypsin deficiency (AATD) leads to disabling chronic obstructive pulmonary disease (COPD). Current therapy aimed at slowing lung disease progression includes exogenous alpha-1 antitrypsin augmentation therapy, but there are few potential new treatments under development. Currently used measurements of AATD-related emphysema include the forced expiratory volume in 1 second (FEV1) and the diffusing capacity of carbon monoxide (DLCO); both are relatively insensitive to therapy, although computed tomography (CT) lung density measurements have been shown to worsen more slowly in treated patients.

Lipid-Polymer Hybrid Nanoparticles As A Next-Generation Drug Delivery Platform: State Of The Art, Emerging Technologies, And Perspectives., Anubhab Mukherjee, Ariana K Waters, Pranav Kalyan, Achal Singh Achrol, Santosh Kesari, Venkata Yenugonda

Articles, Abstracts, and Reports

Lipid-polymer hybrid nanoparticles (LPHNPs) are next-generation core-shell nanostructures, conceptually derived from both liposome and polymeric nanoparticles (NPs), where a polymer core remains enveloped by a lipid layer. Although they have garnered significant interest, they remain not yet widely exploited or ubiquitous. Recently, a fundamental transformation has occurred in the preparation of LPHNPs, characterized by a transition from a two-step to a one-step strategy, involving synchronous self-assembly of polymers and lipids. Owing to its two-in-one structure, this approach is of particular interest as a combinatorial drug delivery platform in oncology. In particular, the outer surface can be decorated in multifarious ways …
