Bayesmetab: Treatment Of Missing Values In Metabolomic Studies Using A Bayesian Modeling Approach, Jasmit Shah, Guy N. Brock, Jeremy Gaskins

Internal Medicine, East Africa

Background: With the rise of metabolomics, the development of methods to address analytical challenges in the analysis of metabolomics data is of great importance. Missing values (MVs) are pervasive, yet the treatment of MVs can have a substantial impact on downstream statistical analyses. The MVs problem in metabolomics is quite challenging and can arise because the metabolite is not biologically present in the sample, or is present in the sample but at a concentration below the lower limit of detection (LOD), or is present in the sample but undetected due to technical issues related to sample pre-processing steps. The …

To Protect And Provide For Children, Prenatal Substance Use Must Be Considered Abuse., Frank E. E. Vandervort, Vincent J. Palusci

Articles

The use of drugs and alcohol during pregnancy is harmful to the developing child. When children are born having been exposed to these substances, children’s protective services should uniformly substantiate child maltreatment in order to ensure that the child’s parent(s) and the child receive the treatment and services necessary to address the child’s immediate safety, protect the government’s compelling interest in the child’s welfare, and ensure the best long-term outcome for the child.

However, marijuana is also known to exert cardiac effects, such as tachycardia, hypotension, and hypertension. Marijuana has also been described in association with atrial fibrillation, ventricular tachycardia, and cardiac arrest. However, acute coronary syndromes, such as myocardial infarction in the setting of marijuana use, is rare. …

Cold Exposure Induces Dynamic, Heterogeneous Alterations In Human Brown Adipose Tissue Lipid Content, Crystal L. Coolbaugh, Bruce M. Damon, Emily C. Bush, E Brian Welch, Theodore F. Towse

Peer Reviewed Articles

Brown adipose tissue undergoes a dynamic, heterogeneous response to cold exposure that can include the simultaneous synthesis, uptake, and oxidation of fatty acids. The purpose of this work was to quantify these changes in brown adipose tissue lipid content (fat-signal fraction (FSF)) using fat-water magnetic resonance imaging during individualized cooling to 3 °C above a participant’s shiver threshold. Eight healthy men completed familiarization, perception-based cooling, and MRI-cooling visits. FSF maps of the supraclavicular region were acquired in thermoneutrality and during cooling (59.5 ± 6.5 min). Brown adipose tissue regions of interest were defined, and voxels were grouped into FSF decades …

Penicillin Allergy Assessment And Skin Testing In The Outpatient Setting, Wesley D. Kufel, Julie Ann Justo, P. Brandon Bookstaver, Lisa M. Avery

Faculty Publications

Penicillin allergies are among of the most commonly reported allergies, yet only 10% of these patients are truly allergic. This leads to potential inadvertent negative consequences for patients and makes treatment decisions challenging for clinicians. Thus, allergy assessment and penicillin skin testing (PST) are important management strategies to reconcile and clarify labeled penicillin allergies. While PST is more common in the inpatient setting where the results will immediately impact antibiotic management, this process is becoming of increasing importance in the outpatient setting. PST in the outpatient setting allows clinicians to proactively de-label and educate patients accordingly so beta-lactam antibiotics may …

Synthesizing Galactose Modified Polymeric Nanoparticles For Biofilm Inhibition Of Pseudomonas Aeruginosa, Tyler R. Flockton

Theses and Dissertations

Treating patients with antibiotics is becoming harder with the increase in antibiotic resistance. This is due to the widespread antibiotic use in clinical and agricultural settings. With antibiotic resistance outpacing new drugs making it to the market, developing new options to treat bacterial infections is and will be important. We created sugar modified nanoparticles to inhibit the biofilm formation of Pseudomonas aeruginosa.

P. aeruginosa is a gram-negative opportunistic pathogen that infects its host that has a compromised immune system. This makes it one of the most significant bacterial infection in hospitals. P. aeruginosa uses biofilms as an attack mechanism …

The purpose of this study is to identify how ankle and midtarsal joint quasi-stiffness are affected by added body mass during over-ground walking. Healthy participants walked barefoot over-ground at 1.25 m/s wearing a weighted vest with 0%, 15% and 30% additional body mass. The effect of added mass was investigated on ankle and midtarsal joint range of motion (ROM), peak moment and quasi-stiffness. Joint quasi-stiffness was broken …

Creating A Molecular Map Of The Pediatric Lung, Quinlen F. Marshall

Forum Lectures

The newborn lung undergoes vast biochemical and physiological changes during adaptation from the intrauterine to the extrauterine environment. Lung morphogenesis continues from birth into early childhood, mediated by dynamic gene expression and a diversity of pulmonary cell types that exhibit remarkable heterogeneity. (Whitsett, JA. et al. Physiol. Rev, 2019). Surprisingly, few studies have solely focused on human lung development during this critical period, and many current studies of lung maturation rely on adult, murine, or diseased samples, limiting their insights and applicability to longitudinal pediatric lung development. Understanding the molecular and physiological nuances of pulmonary development has important clinical relevance, …

Sample Dnp Project Criteria, Ann M. Mayo Rn, Dnsc, Faan

School of Nursing and Health Science: Faculty Scholarship

These sample criteria for Doctorate of Nursing Practice (DNP) projects will be helpful to DNP faculty and students alike. Many nursing faculty teaching in DNP programs have never conducted an Evidence-based Practice Project and so the criteria are meant to be a guide for their learning and help to differentiate DNP projects from research. Research criteria should not be used for DNP project planning or evaluation. Students will benefit from the criteria as they plan and carry out their projects. Criteria should be supplemented by reading examples of strong EBP projects. Readers should critique such publications using the DNP criteria …

Slc36a1-Mtorc1 Signaling Drives Acquired Resistance To Cdk4/6 Inhibitors., Akihiro Yoshida, Yiwen Bu, Shuo Qie, John Wrangle, E. Ramsay Camp, E. Starr Hazard, Gary Hardiman, Renée De Leeuw, Karen E. Knudsen, J. Alan Diehl

Department of Cancer Biology Faculty Papers

The cyclin-dependent kinase 4/6 (CDK4/6) kinase is dysregulated in melanoma, highlighting it as a potential therapeutic target. CDK4/6 inhibitors are being evaluated in trials for melanoma and additional cancers. While beneficial, resistance to therapy is a concern, and the molecular mechanisms of such resistance remain undefined. We demonstrate that reactivation of mammalian target of rapamycin 1 (mTORC1) signaling through increased expression of the amino acid transporter, solute carrier family 36 member 1 (SLC36A1), drives resistance to CDK4/6 inhibitors. Increased expression of SLC36A1 reflects two distinct mechanisms: (i) Rb loss, which drives SLC36A1 via reduced suppression of E2f; (ii) fragile X …

The Cost-Effectiveness Of Neonatal Versus Prenatal Screening For Congenital Toxoplasmosis, Christine Binquet, Catherine Lejeune, Valérie Seror, François Peyron, Anne-Claire Bertaux, Olivier Scemama, Catherine Quantin, Sophie Béjean, Eileen Stillwaggon, Martine Wallon

Economics Faculty Publications

Congenital Toxoplasmosis (CT) can have severe consequences. France, Austria, and Slovenia have prenatal screening programs whereas some other countries are considering universal screening to reduce congenital transmission and severity of infection in children. The efficiency of such programs is debated increasingly as seroprevalence among pregnant women and incidence of congenital toxoplasmosis show a steady decrease. In addition, uncertainty remains regarding the effectiveness of pre- and postnatal treatments.

Comparison Of Lumbar Laminectomy Alone, Lumbar Laminectomy And Fusion, Stand-Alone Anterior Lumbar Interbody Fusion, And Stand-Alone Lateral Lumbar Interbody Fusion For Treatment Of Lumbar Spinal Stenosis: A Review Of The Literature., Manan Shah, Bradley Kolb, Emre Yilmaz, Dia R Halalmeh, Marc D Moisi

Articles, Abstracts, and Reports

Lumbar spinal stenosis is defined as narrowing of the lumbar spinal canal, which causes compression of the spinal cord and nerves. Spinal stenosis can cause leg pain and potentially back pain that can affect the quality of life. Ultimately, surgical decompression is required to alleviate the symptoms. In this review, we first utilize several important studies to compare lumbar laminectomy alone versus lumbar laminectomy and fusion. We also compare the effectiveness of more novel surgical approaches, stand-alone anterior lumbar interbody fusion (ALIF), and stand-alone lateral lumbar interbody fusion (LLIF). These techniques have their own advantages and disadvantages in which many …

Estimated Cardiorespiratory Fitness Is Associated With Reported Depression In College Students, Sharon Jalene, Jennifer Pharr, Guogen Shan, Brach Poston

Integrated Health Sciences Faculty Research

Depression is a serious but treatable health issue that affects college students at an alarming rate. Improved cardiorespiratory fitness (CRF) decreases depression risk and severity but this relationship has not been fully evaluated in the college student population. Non-exercise estimated CRF (eCRF) could be used to identify students at risk for or suffering from depression. This study investigated the associations of depression and eCRF in college students. Participants (N = 437) completed a survey which included demographic and student-status questions, eCRF variables, and a validated depression instrument. Descriptive, chi-square, t-test, regression, and odds ratio analyses were employed. Depression was associated …

Heme And Hemoglobin Utilization By Mycobacterium Tuberculosis., Avishek Mitra, Ying-Hui Ko, Gino Cingolani, Michael Niederweis

Department of Biochemistry and Molecular Biology Faculty Papers

Iron is essential for growth of Mycobacterium tuberculosis (Mtb), but most iron in the human body is stored in heme within hemoglobin. Here, we demonstrate that the substrate-binding protein DppA of the inner membrane Dpp transporter is required for heme and hemoglobin utilization by Mtb. The 1.27 Å crystal structure of DppA shows a tetrapeptide bound in the protein core and a large solvent-exposed crevice for heme binding. Mutation of arginine 179 in this cleft eliminates heme binding to DppA and prevents heme utilization by Mtb. The outer membrane proteins PPE36 and PPE62 are also required for heme and hemoglobin …

Xpert® Mtb/Rif Assay On Formalin-Fixed Paraffin-Embedded Tissues In The Diagnosis Of Extrapulmonary Tuberculosis, Allan Njau, Samuel Gakinya, Shahin Sayed, Zahir Moloo

Pathology, East Africa

Background: Diagnosis of extrapulmonary tuberculosis continues to be a challenge due to the complexity of the causative organism and the wide array of pathologic features seen in this infection. Xpert MTB/RIF can be used on fresh or frozen tissue specimens for diagnosis of tuberculosis with good results. However, there is little data on its use with formalin-fixed paraffin-embedded (FFPE) tissues.

Objectives: The aim of this study was to demonstrate the potential utility of Xpert MTB/RIF and to compare its performance to Ziehl-Neelsen staining for the detection of Mycobacterium tuberculosis from FFPE tissues using histological features from haematoxylin and eosin staining …
