Coronavirus Proteins As Ion Channels: Current And Potential Research, Conor Mcclenaghan, Alex Hanson, Sun-Joo Lee, Colin G Nichols

Open Access Publications

Coronavirus (CoV) outbreaks have recently emerged as a global public health threat due to their exceptional zoonotic potential - a feature arising from their ability to infect a diverse range of potential hosts combined with their high capacity for mutation and recombination. After Severe Acute Respiratory Syndrome (SARS) CoV-1 in 2003 and Middle East Respiratory Syndrome (MERS) CoV in 2012, with the current SARS-CoV-2 pandemic we are now in the midst of the third deadly international CoV outbreak in less than 20 years. Coronavirus outbreaks present a critical threat to global public health and an urgent necessity for therapeutic options. …

Importance: Adults with Down syndrome (DS) are at high-risk of revealing Alzheimer's disease (AD) pathology, in part due to the triplication of chromosome 21 encoding the amyloid precursor protein. Adults with DS are uniformly affected by AD pathology by their 30's and have a 70% to 80% chance of clinical dementia by their 60's. Our previous studies have assessed longitudinal changes in amyloid beta (Aβ) accumulation in DS.

Objective: The goal of the present study was to assess the presence of brain tau using [

Chikungunya Virus Strains From Each Genetic Clade Bind Sulfated Glycosaminoglycans As Attachment Factors, Nicole Mcallister, Michael S. Diamond, Et Al

Open Access Publications

Chikungunya virus (CHIKV) is an arthritogenic alphavirus that causes debilitating musculoskeletal disease. CHIKV displays broad cell, tissue, and species tropism, which may correlate with the attachment factors and entry receptors used by the virus. Cell surface glycosaminoglycans (GAGs) have been identified as CHIKV attachment factors. However, the specific types of GAGs and potentially other glycans to which CHIKV binds and whether there are strain-specific differences in GAG binding are not fully understood. To identify the types of glycans bound by CHIKV, we conducted glycan microarray analyses and discovered that CHIKV preferentially binds GAGs. Microarray results also indicate that sulfate groups …

Myd88-Dependent Influx Of Monocytes And Neutrophils Impairs Lymph Node B Cell Responses To Chikungunya Virus Infection Via Irf5, Nos2 And Nox2, Mary K. Mccarthy, Glennys V. Reynoso, Emma S. Winkler, Matthias Mack, Michael S. Diamond, Heather D. Hickman, Thomas E. Morrison

Open Access Publications

Humoral immune responses initiate in the lymph node draining the site of viral infection (dLN). Some viruses subvert LN B cell activation; however, our knowledge of viral hindrance of B cell responses of important human pathogens is lacking. Here, we define mechanisms whereby chikungunya virus (CHIKV), a mosquito-transmitted RNA virus that causes outbreaks of acute and chronic arthritis in humans, hinders dLN antiviral B cell responses. Infection of WT mice with pathogenic, but not acutely cleared CHIKV, induced MyD88-dependent recruitment of monocytes and neutrophils to the dLN. Blocking this influx improved lymphocyte accumulation, dLN organization, and CHIKV-specific B cell responses. …

Gardnerella Vaginalis As A Cause Of Bacterial Vaginosis: Appraisal Of The Evidence From In Vivo Models, Sydney Morrill, Nicole M Gilbert, Amanda L Lewis

Open Access Publications

Koch's postulates dictate the use of experimental models to illustrate features of human disease and provide evidence for a singular organism as the cause. The underlying cause(s) of bacterial vaginosis (BV) has been debated in the literature for over half a century. In 1955, it was first reported that a bacterium now known as

Surgeon Choice In The Use Of Postdischarge Antibiotics For Prophylaxis Following Mastectomy With And Without Breast Reconstruction, David K Warren, Katelin B Nickel, Christopher J Hostler, Katherine Foy, Jennifer H Han, Pam Tolomeo, Ian R Banks, Victoria J Fraser, Margaret A Olsen, Cdc Prevention Epicenter Program

Open Access Publications

Multiple guidelines recommend discontinuation of prophylactic antibiotics <24 hours after surgery. In a multicenter, retrospective cohort of 2,954 mastectomy patients ± immediate breast reconstruction, we found that utilization of prophylactic postdischarge antibiotics varied dramatically at the surgeon level among general surgeons and was virtually universal among plastic surgeons.

Use Of Icd-10 Codes For Identification Of Injection Drug Use-Associated Infective Endocarditis Is Nonspecific And Obscures Critical Findings On Impact Of Medications For Opioid Use Disorder, Laura R. Marks, Nathanial S. Nolan, Linda Jiang, Dharushana Muthulingam, Stephen Y. Liang, Michael J. Durkin

Open Access Publications

Background: No International Classification of Diseases, 10th revision (ICD-10), diagnosis code exists for injection drug use-associated infective endocarditis (IDU-IE). Instead, public health researchers regularly use combinations of nonspecific ICD-10 codes to identify IDU-IE; however, the accuracy of these codes has not been evaluated.

Methods: We compared commonly used ICD-10 diagnosis codes for IDU-IE with a prospectively collected patient cohort diagnosed with IDU-IE at Barnes-Jewish Hospital to determine the accuracy of ICD-10 diagnosis codes used in IDU-IE research.

Results: ICD-10 diagnosis codes historically used to identify IDU-IE were inaccurate, missing 36.0% and misclassifying 56.4% of patients prospectively identified in this cohort. …

Open Access Publications

Why ocular mucosa is paucibacterial is unknown. Many different mechanisms have been suggested but the comprehensive experimental studies are sparse. We found that a deficiency in L-plastin (LCP1), an actin bundling protein, resulted in an ocular commensal overgrowth, characterized with increased presence of conjunctival

Assessment Of Plasma Amyloid-Β42/40 And Cognitive Decline Among Community-Dwelling Older Adults, Kelly Virecoulon Giudici, Philipe De Souto Barreto, Sophie Guyonnet, Yan Li, Randall J. Bateman, Bruno Vellas

Importance: Plasma measurement of amyloid-β (Aβ) peptides has been associated with cognitive function, but evidence of its ability to identify cognitive decline is still scarce.

Objective: To investigate the associations between plasma Aβ42/40 and cognitive decline over time among community-dwelling older adults with subjective memory concerns.

Design, Setting, and Participants: This multicenter cohort study used data from volunteers in the 5-year study Multidomain Alzheimer Preventive Trial (MAPT). Participants were aged 70 years or older and observed for a median (interquartile range) of 3.9 (2.0-4.0) years. Recruitment of participants started in May 2008 and ended in February 2011. Follow-up ended in …

Lipin-1 Contributes To Il-4 Mediated Macrophage Polarization, Sunitha Chandran, Robert M Schilke, Cassidy M R Blackburn, Aila Yurochko, Rusella Mirza, Rona S Scott, Brian N Finck, Matthew D Woolard

Open Access Publications

Macrophage responses contribute to a diverse array of pathologies ranging from infectious disease to sterile inflammation. Polarization of macrophages determines their cellular function within biological processes. Lipin-1 is a phosphatidic acid phosphatase in which its enzymatic activity contributes to macrophage pro-inflammatory responses. Lipin-1 also possesses transcriptional co-regulator activity and whether this activity is required for macrophage polarization is unknown. Using mice that lack only lipin-1 enzymatic activity or both enzymatic and transcriptional coregulator activities from myeloid cells, we investigated the contribution of lipin-1 transcriptional co-regulator function toward macrophage wound healing polarization. Macrophages lacking both lipin-1 activities did not elicit IL-4 …

Quantitative Definition Of Neurobehavior, Vision, Hearing And Brain Volumes In Macaques Congenitally Exposed To Zika Virus, Michelle R. Koenig, Kevin Noguchi, Et Al.

Open Access Publications

Congenital Zika virus (ZIKV) exposure results in a spectrum of disease ranging from severe birth defects to delayed onset neurodevelopmental deficits. ZIKV-related neuropathogenesis, predictors of birth defects, and neurodevelopmental deficits are not well defined in people. Here we assess the methodological and statistical feasibility of a congenital ZIKV exposure macaque model for identifying infant neurobehavior and brain abnormalities that may underlie neurodevelopmental deficits. We inoculated five pregnant macaques with ZIKV and mock-inoculated one macaque in the first trimester. Following birth, growth, ocular structure/function, brain structure, hearing, histopathology, and neurobehavior were quantitatively assessed during the first week of life. We identified …

Characterization Of Radiotherapy Component Impact On Mr Imaging Quality For An Mrgrt System, Benjamin C Lewis, Bruce Gu, Ryan Klett, Rajiv Lotey, Olga L Green, Taeho Kim

Open Access Publications

Radiotherapy components of an magnetic resonnace-guided radiotherapy (MRgRT) system can alter the magnetic fields, causing spatial distortion and image deformation, altering imaging and radiation isocenter coincidence and the accuracy of dose calculations. This work presents a characterization of radiotherapy component impact on MR imaging quality in terms of imaging isocenter variation and spatial integrity changes on a 0.35T MRgRT system, pre- and postupgrade of the system. The impact of gantry position, MLC field size, and treatment table power state on imaging isocenter and spatial integrity were investigated. A spatial integrity phantom was used for all tests. Images were acquired for …

Hippocampal Volume In Provisional Tic Disorder Predicts Tic Severity At 12-Month Follow-Up, Soyoung Kim, Deanna J Greene, Carolina Badke D'Andrea, Emily C Bihun, Jonathan M Koller, Bridget O'Reilly, Bradley L Schlaggar, Kevin J Black

Open Access Publications

Previous studies have investigated differences in the volumes of subcortical structures (e.g., caudate nucleus, putamen, thalamus, amygdala, and hippocampus) between individuals with and without Tourette syndrome (TS), as well as the relationships between these volumes and tic symptom severity. These volumes may also predict clinical outcome in Provisional Tic Disorder (PTD), but that hypothesis has never been tested. This study aimed to examine whether the volumes of subcortical structures measured shortly after tic onset can predict tic symptom severity at one-year post-tic onset, when TS can first be diagnosed. We obtained T1-weighted structural MRI scans from 41 children with PTD …

Newborn Screening For Pompe Disease In Illinois: Experience With 684,290 Infants, Barbara K Burton, Joel Charrow, George E Hoganson, Julie Fleischer, Dorothy K Grange, Stephen R Braddock, Lauren Hitchins, Rachel Hickey, Katherine M Christensen, Daniel Groepper, Heather Shryock, Pamela Smith, Rong Shao, Khaja Basheeruddin

Open Access Publications

Statewide newborn screening for Pompe disease began in Illinois in 2015. As of 30 September 2019, a total of 684,290 infants had been screened and 395 infants (0.06%) were screen positive. A total of 29 cases of Pompe disease were identified (3 infantile, 26 late-onset). While many of the remainder were found to have normal alpha-glucosidase activity on the follow-up testing (234 of 395), other findings included 62 carriers, 39 infants with pseudodeficiency, and eight infants who could not be given a definitive diagnosis due to inconclusive follow-up testing.

Mental Health And Weather Extremes In A Southeastern U.S. City: Exploring Group Differences By Race, Lisa Reyes Mason, Bonita B Sharma, Jayme E Walters, Christine C Ekenga

Open Access Publications

The connection between mental health and weather extremes is a public health concern, but less studied to date than physical health. This exploratory study examines the mental health impacts of two kinds of weather extremes increasingly linked to climate change-summer heat waves and extreme winter weather-in a low- to middle-income population in the Southeastern U.S. The distribution of mental health impacts, and potential pathways to them, are examined with a focus on race. Data are from a random-sample survey of 426 participants and are analyzed with bivariate statistics and path analysis. Self-reported mental health impacts, in both seasons, were common …
