Advances And Gaps In Sars-Cov-2 Infection Models, César Muñoz-Fontela, Michael S. Diamond, Et Al

Open Access Publications

The global response to Coronavirus Disease 2019 (COVID-19) is now facing new challenges such as vaccine inequity and the emergence of SARS-CoV-2 variants of concern (VOCs). Preclinical models of disease, in particular animal models, are essential to investigate VOC pathogenesis, vaccine correlates of protection and postexposure therapies. Here, we provide an update from the World Health Organization (WHO) COVID-19 modeling expert group (WHO-COM) assembled by WHO, regarding advances in preclinical models. In particular, we discuss how animal model research is playing a key role to evaluate VOC virulence, transmission and immune escape, and how animal models are being refined to …

Ultrasound-Guided Thrombin Injection For The Treatment Of Bleeding Following Kidney And Liver Biopsies, Mark J Hoegger, William D Middleton

Open Access Publications

The purpose of this study was to describe the technique and outcomes of percutaneous thrombin injection into the superficial aspect of actively bleeding liver and kidney biopsy tracks identified with color Doppler ultrasound with the aim of hemorrhage termination. After percutaneous thrombin injection, 15/16 (94%) patients did not require further intervention. Ultrasound-guided thrombin injection into the superficial site of active bleeding is an effective technique for terminating bleeding in the immediate post-procedure period following kidney and liver biopsies and should be considered if active bleeding persists on color Doppler after ≥30 minutes of compression and observation.

Pulmonary Capillary Recruitment And Distention In Mammalian Lungs: Species Similarities, David Langleben, Benjamin D. Fox, Stylianos E. Orfanos, Michele Giovinazzo, John D. Catravas

Bioelectrics Publications

Pulmonary arterial pressure rises minimally during exercise. The pulmonary microcirculation accommodates increasing blood flow via recruitment of pulmonary capillaries and, at higher flows, by distention of already perfused capillaries. The flow transition range between recruitment and distention has not been studied or compared across mammalian species, including humans. We hypothesised that the range would be similar. Functional pulmonary capillary surface area (FCSA) can be estimated using validated metabolic techniques. We reviewed data from previous studies in three mammalian species (perfused rabbit lungs and dog lung lobes, and exercising humans) and generated blood flow-FCSA curves over a range of flows. We …

Prevalence Versus Evidence: A Closer Look At The Research Available For Serving Children Exposed To Maltreatment And A Response To Hyter's Call For Trauma-Informed Care, Savanah Gayaldo, Allison Gladfelter

Faculty Articles, Papers, and Other Scholarship

Purpose:

In an October 2021 post of The ASHA LeaderLive, Dr. Yvette Hyter emphasized the need for trauma-informed services for children exposed to maltreatment in the wake of the COVID-19 pandemic. Inspired by her call, we discuss how the pandemic created a high-risk context for maltreatment, the speech-language pathologists' (SLPs') role in prevention and intervention, reflect on the gap in evidence for maltreatment within empirical journals aimed at the speech-language pathology audience, and reiterate Hyter's call for trauma-informed care as a guide for clinicians serving children exposed to maltreatment.

Method:

We searched for empirical evidence within journals aimed at …

Edge-Centric Analysis Of Stroke Patients: An Alternative Approach For Biomarkers Of Lesion Recovery, Sebastian Idesis, Joshua Faskowitz, Richard F Betzel, Maurizio Corbetta, Olaf Sporns, Gustavo Deco

2020-Current year OA Pubs

Most neuroimaging studies of post-stroke recovery rely on analyses derived from standard node-centric functional connectivity to map the distributed effects in stroke patients. Here, given the importance of nonlocal and diffuse damage, we use an edge-centric approach to functional connectivity in order to provide an alternative description of the effects of this disorder. These techniques allow for the rendering of metrics such as normalized entropy, which describes the diversity of edge communities at each node. Moreover, the approach enables the identification of high amplitude co-fluctuations in fMRI time series. We found that normalized entropy is associated with stroke lesion severity …

Neonatal Motor Functional Connectivity And Motor Outcomes At Age Two Years In Very Preterm Children With And Without High-Grade Brain Injury, Peppar E P Cyr, Rachel E Lean, Jeanette K Kenley, Sydney Kaplan, Dominique E Meyer, Jeffery J Neil, Dimitrios Alexopoulos, Rebecca G Brady, Joshua S Shimony, Thomas L Rodebaugh, Cynthia E Rogers, Christopher D Smyser

2020-Current year OA Pubs

Preterm-born children have high rates of motor impairments, but mechanisms for early identification remain limited. We hypothesized that neonatal motor system functional connectivity (FC) would relate to motor outcomes at age two years; currently, this relationship is not yet well-described in very preterm (VPT; born <32 weeks' gestation) infants with and without brain injury. We recruited 107 VPT infants - including 55 with brain injury (grade III-IV intraventricular hemorrhage, cystic periventricular leukomalacia, post-hemorrhagic hydrocephalus) - and collected FC data at/near term-equivalent age (35-45 weeks postmenstrual age). Correlation coefficients were used to calculate the FC between bilateral motor and visual cortices and thalami. At two years corrected-age, motor outcomes were assessed with the Bayley Scales of Infant and Toddler Development, 3rd edition. Multiple imputation was used to estimate missing data, and regression models related FC measures to motor outcomes. Within the brain-injured group only, interhemispheric motor cortex FC was positively related to gross motor outcomes. Thalamocortical and visual FC were not related to motor scores. This suggests neonatal alterations in motor system FC may provide prognostic information about impairments in children with brain injury.

Inferring The Dynamical Effects Of Stroke Lesions Through Whole-Brain Modeling, Sebastian Idesis, Chiara Favaretto, Nicholas V Metcalf, Joseph C Griffis, Gordon L Shulman, Maurizio Corbetta, Gustavo Deco

2020-Current year OA Pubs

Understanding the effect of focal lesions (stroke) on brain structure-function traditionally relies on behavioral analyses and correlation with neuroimaging data. Here we use structural disconnection maps from individual lesions to derive a causal mechanistic generative whole-brain model able to explain both functional connectivity alterations and behavioral deficits induced by stroke. As compared to other models that use only the local lesion information, the similarity to the empirical fMRI connectivity increases when the widespread structural disconnection information is considered. The presented model classifies behavioral impairment severity with higher accuracy than other types of information (e.g.: functional connectivity). We assessed topological measures …

Creation Of Philadelphia Chromosome By Crispr/Cas9-Mediated Double Cleavages On Bcr And Abl1 Genes As A Model For Initial Event In Leukemogenesis, Minori Tamai, Kenji Kamimoto, Kohei Omachi, Et Al.

2020-Current year OA Pubs

The Philadelphia (Ph) chromosome was the first translocation identified in leukemia. It is supposed to be generated by aberrant ligation between two DNA double-strand breaks (DSBs) at the BCR gene located on chromosome 9q34 and the ABL1 gene located on chromosome 22q11. Thus, mimicking the initiation process of translocation, we induced CRISPR/Cas9-mediated DSBs simultaneously at the breakpoints of the BCR and ABL1 genes in a granulocyte-macrophage colony-stimulating factor (GM-CSF) dependent human leukemia cell line. After transfection of two single guide RNAs (sgRNAs) targeting intron 13 of the BCR gene and intron 1 of the ABL1 gene, a factor-independent subline was …

Estimation Of Intrafamilial Dna Contamination In Family Trio Genome Sequencing Using Deviation From Mendelian Inheritance, Christopher J Yoon, Brian Wiley, Malachi Griffith, Obi L Griffith, Et Al.

2020-Current year OA Pubs

With the increasing number of sequencing projects involving families, quality control tools optimized for family genome sequencing are needed. However, accurately quantifying contamination in a DNA mixture is particularly difficult when genetically related family members are the sources. We developed TrioMix, a maximum likelihood estimation (MLE) framework based on Mendel's law of inheritance, to quantify DNA mixture between family members in genome sequencing data of parent-offspring trios. TrioMix can accurately deconvolute any intrafamilial DNA contamination, including parent-offspring, sibling-sibling, parent-parent, and even multiple familial sources. In addition, TrioMix can be applied to detect genomic abnormalities that deviate from Mendelian inheritance patterns, …

Induction Egfr Tyrosine Kinase Inhibitors Prior To Definitive Chemoradiotherapy In Unresectable Stage Iii Egfr-Mutated Non-Small Cell Lung Cancer, Jacqueline V Aredo, Heather A Wakelee, Angela Bik-Yu Hui, Sukhmani K Padda, Nitin D Joshi, H Henry Guo, Aadel Chaudhuri, Maximilian Diehn, Billy W Loo Jr, Joel W Neal

2020-Current year OA Pubs

INTRODUCTION: Increasing evidence suggests that consolidation durvalumab confers limited benefits for patients with stage III EGFR-mutated NSCLC. Induction or maintenance EGFR tyrosine kinase inhibitors (TKIs) added to concurrent chemoradiotherapy (CRT) may optimize definitive treatment, but there are limited data supporting an induction TKI strategy.

METHODS: We evaluated the efficacy and safety of induction EGFR TKIs administered before concurrent CRT in a retrospective series of patients with unresectable locally advanced EGFR-mutated NSCLC. Circulating tumor DNA (ctDNA) analysis was performed on a patient subset using CAPP-seq and correlated with outcomes.

RESULTS: Of six patients, three received erlotinib and three osimertinib as induction …

Detection Of Emerging Neurodegeneration Using Bayesian Linear Mixed-Effect Modeling, Yann Cobigo, Richard J Perrin, Et Al.

2020-Current year OA Pubs

Early detection of neurodegeneration, and prediction of when neurodegenerative diseases will lead to symptoms, are critical for developing and initiating disease modifying treatments for these disorders. While each neurodegenerative disease has a typical pattern of early changes in the brain, these disorders are heterogeneous, and early manifestations can vary greatly across people. Methods for detecting emerging neurodegeneration in any part of the brain are therefore needed. Prior publications have described the use of Bayesian linear mixed-effects (BLME) modeling for characterizing the trajectory of change across the brain in healthy controls and patients with neurodegenerative disease. Here, we use an extension …

Median survival of patients with glioblastoma (GBM) treated with standard of care which consists of maximal safe resection of the contrast-enhancing portion of the tumor followed by radiation therapy with concomitant adjuvant temozolomide (TMZ) remains 15 months. The tumor microenvironment (TME) is known to contain immune suppressive myeloid cells with minimal effector T cell infiltration. Stimulator of interferon genes (STING) is an important activator of immune response and results in production of Type 1 interferon and antigen presentation by myeloid cells. This review will discuss important developments in STING agonists, potential biomarkers for STING response, and new combinatorial therapeutic approaches …

A Role For An Htlv-1 Vaccine?, Lee Ratner

2020-Current year OA Pubs

HTLV-1 is a global infection with 5-20 million infected individuals. Although only a minority of infected individuals develop myelopathy, lymphoproliferative malignancy, or inflammatory disorders, infection is associated with immunosuppression and shorter survival. Transmission of HTLV-1 is through contaminated blood or needles, mother-to-child exposure through breast-feeding, and sexual intercourse. HTLV-1 is a delta retrovirus that expresses immunogenic Gag, Envelope, TAX, and Hbz proteins. Neutralizing antibodies have been identified directed against the surface envelope protein, and cytotoxic T-cell epitopes within TAX have been characterized. Thus far, there have been few investigations of vaccines directed against each of these proteins, with limited responses, …

Simultaneous pancreas-kidney transplantation (SPK) carries about a 7%-22% risk of technical failure, but the impact of early pancreas allograft loss on subsequent kidney graft and patient survival is not well-defined. We examined national transplant registry data for type 1 diabetic patients who received SPK between 2000 and 2021. Associations of transplant type (i.e., SPK, deceased-donor kidney transplant [DDKA], living-donor kidney transplant [LDKA]) with kidney graft failure and patient survival were estimated by multivariable inverse probability of treatment-weighted accelerated failure-time models. Compared to SPK recipients with a functioning pancreas graft 3 months posttransplant (SPK,P+), LDKA had 18% (Time Ratio [TR] 0.82, …

Apoe Mediated Neuroinflammation And Neurodegeneration In Alzheimer's Disease, Samira Parhizkar, David M Holtzman

2020-Current year OA Pubs

Neuroinflammation is a central mechanism involved in neurodegeneration as observed in Alzheimer's disease (AD), the most prevalent form of neurodegenerative disease. Apolipoprotein E4 (APOE4), the strongest genetic risk factor for AD, directly influences disease onset and progression by interacting with the major pathological hallmarks of AD including amyloid-β plaques, neurofibrillary tau tangles, as well as neuroinflammation. Microglia and astrocytes, the two major immune cells in the brain, exist in an immune-vigilant state providing immunological defense as well as housekeeping functions that promote neuronal well-being. It is becoming increasingly evident that under disease conditions, these immune cells become progressively dysfunctional in …
