Mr Elastography Demonstrates Reduced White Matter Shear Stiffness In Early-Onset Hydrocephalus, M E Wagshul, J P Mcallister, D D Limbrick Jr, S Yang, W Mowrey, J T Goodrich, A Meiri, D M Morales, A Kobets, R Abbott

Open Access Publications

INTRODUCTION: Hydrocephalus that develops early in life is often accompanied by developmental delays, headaches and other neurological deficits, which may be associated with changes in brain shear stiffness. However, noninvasive approaches to measuring stiffness are limited. Magnetic Resonance Elastography (MRE) of the brain is a relatively new noninvasive imaging method that provides quantitative measures of brain tissue stiffness. Herein, we aimed to use MRE to assess brain stiffness in hydrocephalus patients compared to healthy controls, and to assess its associations with ventricular size, as well as demographic, shunt-related and clinical outcome measures.

METHODS: MRE was collected at two imaging sites …

Pathways To Care And Preferences For Improving Tuberculosis Services Among Tuberculosis Patients In Zambia: A Discrete Choice Experiment, Andrew D. Kerkhoff, Mary Kagujje, Sarah Nyangu, Kondwelani Mateyo, Nsala Sanjase, Lophina Chilukutu, Ingrid Eshun-Wilson, Elvin H. Geng, Diane V. Havlir, Monde Muyoyeta

Open Access Publications

BACKGROUND: Delays in the diagnosis of tuberculosis (TB) contribute to a substantial proportion of TB-related mortality, especially among people living with HIV (PLHIV). We sought to characterize the diagnostic journey for HIV-positive and HIV-negative patients with a new TB diagnosis in Zambia, to understand drivers of delay, and characterize their preferences for service characteristics to inform improvements in TB services.

METHODS: We assessed consecutive adults with newly microbiologically-confirmed TB at two public health treatment facilities in Lusaka, Zambia. We administered a survey to document critical intervals in the TB care pathway (time to initial care-seeking, diagnosis and treatment initiation), identify …

Fluvoxamine: A Review Of Its Mechanism Of Action And Its Role In Covid-19, Vikas P Sukhatme, Angela M Reiersen, Sharat J Vayttaden, Vidula V Sukhatme

Open Access Publications

Fluvoxamine is a well-tolerated, widely available, inexpensive selective serotonin reuptake inhibitor that has been shown in a small, double-blind, placebo-controlled, randomized study to prevent clinical deterioration of patients with mild coronavirus disease 2019 (COVID-19). Fluvoxamine is also an agonist for the sigma-1 receptor, through which it controls inflammation. We review here a body of literature that shows important mechanisms of action of fluvoxamine and other SSRIs that could play a role in COVID-19 treatment. These effects include: reduction in platelet aggregation, decreased mast cell degranulation, interference with endolysosomal viral trafficking, regulation of inositol-requiring enzyme 1α-driven inflammation and increased melatonin levels, …

Are Fc Gamma Receptor Polymorphisms Important In Hiv-1 Infection Outcomes And Latent Reservoir Size?, Helena Lamptey, Evelyn Y Bonney, Bright Adu, George B Kyei

Open Access Publications

Fc gamma receptors (FcγR) are cell surface glycoproteins which trigger specific effector-cell responses when cross-linked with the Fc portions of immunoglobulin (IgG) antibodies. During HIV-1 infection, the course of disease progression, ART response, and viral reservoir size vary in different individuals. Several factors may account for these differences; however, Fc gamma receptor gene polymorphisms, which influence receptor binding to IgG antibodies, are likely to play a key role. FcγRIIa (CD32) was recently reported as a potential marker for latent HIV reservoir, however, this assertion is still inconclusive. Whether FcγR polymorphisms influence the size of the viral reservoir, remains an important …

Clinical And Immunological Factors That Distinguish Covid-19 From Pandemic Influenza A(H1n1), José Alberto Choreño-Parra, Shabaana A Khader, Et Al

Open Access Publications

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of coronavirus disease 2019 (COVID-19), is a global health threat with the potential to cause severe disease manifestations in the lungs. Although COVID-19 has been extensively characterized clinically, the factors distinguishing SARS-CoV-2 from other respiratory viruses are unknown. Here, we compared the clinical, histopathological, and immunological characteristics of patients with COVID-19 and pandemic influenza A(H1N1). We observed a higher frequency of respiratory symptoms, increased tissue injury markers, and a histological pattern of alveolar pneumonia in pandemic influenza A(H1N1) patients. Conversely, dry cough, gastrointestinal symptoms and interstitial lung pathology were …

Fractal Motor Activity Regulation And Sex Differences In Preclinical Alzheimer's Disease Pathology, Lei Gao, Peng Li, Arlen Gaba, Erik Musiek, Yo-El S Ju, Kun Hu

Open Access Publications

Introduction: Degradation in fractal motor activity regulation (FMAR), a measure of multiscale self-similarity of motor control, occurs in aging and accelerates with clinical progression to Alzheimer's disease (AD). Whether FMAR changes occur during the pre-symptomatic phase of the disease in women and men remains unknown.

Methods: FMAR was assessed in cognitively normal participants (n = 178) who underwent 7 to 14 days of home actigraphy. Preclinical AD pathology was determined by amyloid imaging-Pittsburgh compound B (PiB) and cerebrospinal fluid (CSF) phosphorylated-tau181 (p-tau) to amyloid beta 42 (Aβ42) ratio.

Results: Degradation in daytime FMAR was overall significantly associated with preclinical amyloid …

Joint Degeneration In A Mouse Model Of Pseudoachondroplasia: Er Stress, Inflammation, And Block Of Autophagy, Jacqueline T Hecht, Alka C Veerisetty, Mohammad G Hossain, Debabrata Patra, Frankie Chiu, Francoise Coustry, Karen L Posey

Open Access Publications

Pseudoachondroplasia (PSACH), a short limb skeletal dysplasia associated with premature joint degeneration, is caused by misfolding mutations in cartilage oligomeric matrix protein (COMP). Here, we define mutant-COMP-induced stress mechanisms that occur in articular chondrocytes of MT-COMP mice, a murine model of PSACH. The accumulation of mutant-COMP in the ER occurred early in MT-COMP articular chondrocytes and stimulated inflammation (TNFα) at 4 weeks, and articular chondrocyte death increased at 8 weeks while ER stress through CHOP was elevated by 12 weeks. Importantly, blockage of autophagy (pS6), the major mechanism that clears the ER, sustained cellular stress in MT-COMP articular chondrocytes. Degeneration …

Sustained Oxygenation Accelerates Diabetic Wound Healing By Promoting Epithelialization And Angiogenesis And Decreasing Inflammation, Ya Guan, Hong Niu, Zhongting Liu, Yu Dang, Jie Shen, Mohamed Zayed, Liang Ma, Jianjun Guan

Open Access Publications

Nonhealing diabetic wounds are common complications for diabetic patients. Because chronic hypoxia prominently delays wound healing, sustained oxygenation to alleviate hypoxia is hypothesized to promote diabetic wound healing. However, sustained oxygenation cannot be achieved by current clinical approaches, including hyperbaric oxygen therapy. Here, we present a sustained oxygenation system consisting of oxygen-release microspheres and a reactive oxygen species (ROS)-scavenging hydrogel. The hydrogel captures the naturally elevated ROS in diabetic wounds, which may be further elevated by the oxygen released from the administered microspheres. The sustained release of oxygen augmented the survival and migration of keratinocytes and dermal fibroblasts, promoted angiogenic …

Outcomes Associated With Social Distancing Policies In St Louis, Missouri, During The Early Phase Of The Covid-19 Pandemic, Elvin H. Geng, Joshua Schwab, Randi Foraker, Branson Fox, Christine M. Hoehner, Mario Schootman, Aaloke Mody, William Powderly, Byron Yount, Keith Woeltje, Maya Petersen

Open Access Publications

Importance: In the absence of a national strategy in response to the COVID-19 pandemic, many public health decisions fell to local elected officials and agencies. Outcomes of such policies depend on a complex combination of local epidemic conditions and demographic features as well as the intensity and timing of such policies and are therefore unclear.

Objective: To use a decision analytical model of the COVID-19 epidemic to investigate potential outcomes if actual policies enacted in March 2020 (during the first wave of the epidemic) in the St Louis region of Missouri had been delayed.

Design, Setting, and Participants: A previously …

Glial-Specific Deletion Of Med12 Results In Rapid Hearing Loss Via Degradation Of The Stria Vascularis, Teng-Wei Huang, Amrita A. Iyer, Jeanne M. Manalo, Junsung Woo, Navish A.

Mediator protein complex subunit 12 (Med12) is a core component of the basal transcriptional apparatus and plays a critical role in the development of many tissues. Mutations in Med12 are associated with X-linked intellectual disability syndromes and hearing loss; however, its role in nervous system function remains undefined. Here, we show that temporal conditional deletion of Med12 in astrocytes in the adult CNS results in region-specific alterations in astrocyte morphology. Surprisingly, behavioral studies revealed rapid hearing loss after adult deletion of Med12 that was confirmed by a complete abrogation of auditory brainstem responses. Cellular analysis of the cochlea revealed degeneration …

Cholestatic Hepatitis In Graves' Disease: A Diagnostic Challenge, Metri Haddaden, Angy Hanna, Fadi Odish, Samir Husami, Zaid Imam, Mamon Tahhan

Open Access Publications

Cholestatic hepatitis is a rare presentation of thyrotoxicosis potentially confused as an adverse effect of antithyroid therapy. We report a 37-year-old man with cholestatic hepatitis as an initial presentation of Graves' disease. Diagnostic evaluation demonstrated (i) elevated transaminases and alkaline phosphatase (R-factor value: 2.6), and marked cholestasis (total bilirubin: 17.3 mg/dL, direct bilirubin: 9.4 mg/dL); (ii) negative hepatitis, viral, and autoimmune serologies; (iii) normal magnetic resonance cholangiopancreatography; (iv) liver biopsy with marked cholestasis and no fibrosis; (v) thyroid-stimulating hormone <0.01, fT4 (free thyroxine): 1.5, fT4 (free triiodothyronine): 4.3 and positive thyroid-stimulating immunoglobulins. Radioiodine uptake scan confirmed Graves' disease. Clinical resolution was achieved with propranolol, prednisone, methimazole, and thyroidectomy.
