Communication Sciences and Disorders Faculty Articles and Research

A picture description task is a component of Miro Health’s platform for self-administration of neurobehavioral assessments. Picture description has been used as a screening tool for identification of individuals with Alzheimer’s disease and mild cognitive impairment (MCI), but currently requires in-person administration and scoring by someone with access to and familiarity with a scoring rubric. The Miro Health implementation allows broader use of this assessment through self-administration and automated processing, analysis, and scoring to deliver clinically useful quantifications of the users’ speech production, vocal characteristics, and language. Picture description responses were collected from 62 healthy controls (HC), and 33 participants …

Prognostication Of Dna Damage Response Protein Expression Patterns In Chronic Lymphocytic Leukemia, Ti'ara L Griffen, Fieke W Hoff, Yihua Qiu, Jan Burger, William Wierda, Steven M Kornblau

Faculty, Staff and Student Publications

Proteomic DNA Damage Repair (DDR) expression patterns in Chronic Lymphocytic Leukemia were characterized by quantifying and clustering 24 total and phosphorylated DDR proteins. Overall, three protein expression patterns (C1-C3) were identified and were associated as an independent predictor of distinct patient overall survival outcomes. Patients within clusters C1 and C2 had poorer survival outcomes and responses to fludarabine, cyclophosphamide, and rituxan chemotherapy compared to patients within cluster C3. However, DDR protein expression patterns were not prognostic in more modern therapies with BCL2 inhibitors or a BTK/PI3K inhibitor. Individually, nine of the DDR proteins were prognostic for predicting overall survival and/or …

Functional States Of Myeloid Cells In Cancer, Lilian Van Vlerken-Ysla, Yulia Y Tyurina, Valerian E Kagan, Dmitry I Gabrilovich

Faculty, Staff and Student Publications

Myeloid cells, comprised of macrophages, dendritic cells, monocytes, and granulocytes, represent a major component of the tumor microenvironment (TME) and are critically involved in regulation of tumor progression and metastasis. In recent years, single-cell omics technologies have identified multiple phenotypically distinct subpopulations. In this review, we discuss recent data and concepts suggesting that the biology of myeloid cells is largely defined by a very limited number of functional states that transcend the narrowly defined cell populations. These functional states are primarily centered around classical and pathological states of activation, with the latter state commonly defined as myeloid-derived suppressor cells. We …

Faculty, Staff and Student Publications

BACKGROUND: The mutational landscape of SARS-CoV-2 varies at the dominant viral genome sequence and minor genomic variant population. During the COVID-19 pandemic, an early substitution in the genome was the D614G change in the spike protein, associated with an increase in transmissibility. Genomes with D614G are accompanied by a P323L substitution in the viral polymerase (NSP12). However, P323L is not thought to be under strong selective pressure.

RESULTS: Investigation of P323L/D614G substitutions in the population shows rapid emergence during the containment phase and early surge phase during the first wave. These substitutions emerge from minor genomic variants which become dominant …

Correlation Between Neutrophil-To-Lymphocyte Ratio After Percutaneous Coronary Intervention And The Size Of Infarction In Patients With Acute Myocardial Infarction, Mohamed R. Badran

Journal of Medicine in Scientific Research

Background Inflammatory processes have a role in the pathogenesis of acute myocardial infarction (AMI), left ventricular remodeling, and repair. Infarct size (IS) is a strong predictor of prognosis following AMI. Several tools are used to predict IS, but most of them are expensive and inaccessible all the time. So, neutrophil-to-lymphocyte ratio (NLR) as a marker of inflammation is an easy and cheap tool to predict IS. Aim To assess if post-percutaneous coronary intervention (PCI) NLR can predict IS in patients with AMI. Patients and methods The study included 11 125 patients with AMI treated with primary PCI. We used cardiovascular …

Hypomorphic Brca2 And Rad51c Double Mutant Mice Display Fanconi Anemia, Cancer And Polygenic Replication Stress, Karl-Heinz Tomaszowski, Sunetra Roy, Carolina Guerrero, Poojan Shukla, Caezaan Keshvani, Yue Chen, Martina Ott, Xiaogang Wu, Jianhua Zhang, Courtney D Dinardo, Detlev Schindler, Katharina Schlacher

Faculty, Staff and Student Publications

The prototypic cancer-predisposition disease Fanconi Anemia (FA) is identified by biallelic mutations in any one of twenty-three FANC genes. Puzzlingly, inactivation of one Fanc gene alone in mice fails to faithfully model the pleiotropic human disease without additional external stress. Here we find that FA patients frequently display FANC co-mutations. Combining exemplary homozygous hypomorphic Brca2/Fancd1 and Rad51c/Fanco mutations in mice phenocopies human FA with bone marrow failure, rapid death by cancer, cellular cancer-drug hypersensitivity and severe replication instability. These grave phenotypes contrast the unremarkable phenotypes seen in mice with single gene-function inactivation, revealing an unexpected synergism between Fanc mutations. Beyond …

The regenerative potential of the endometrium is attributed to endometrial stem cells; however, the signaling pathways controlling its regenerative potential remain obscure. In this study, genetic mouse models and endometrial organoids are used to demonstrate that SMAD2/3 signaling controls endometrial regeneration and differentiation. Mice with conditional deletion of SMAD2/3 in the uterine epithelium using Lactoferrin-iCre develop endometrial hyperplasia at 12-weeks and metastatic uterine tumors by 9-months of age. Mechanistic studies in endometrial organoids determine that genetic or pharmacological inhibition of SMAD2/3 signaling disrupts organoid morphology, increases the glandular and secretory cell markers, FOXA2 and MUC1, and alters the genome-wide distribution …

Better Survival In Morbidly Obese Patients With Atrial Fibrillation Treated With Non-Vitamin K-Dependent Oral Anticoagulants, Monirah A. Albabtain, Zaid Alanazi, Nawaf Al Mutairi, Yahya Al Hebaishi, Ola Alyafi, Haneen Alghasoon, Amr A. Arafat

Journal of the Saudi Heart Association

Background: The efficacy and safety of non-vitamin K-dependent anticoagulants (NOAC) are not well investigated in the obese population, and fixed dosing could lead to under-anticoagulation. Our objective was to evaluate the effect of obesity on anticoagulation outcomes and survival in non-valvular atrial fibrillation (AF) patients. Methods: We enrolled 755 patients who required anticoagulation for AF from 2015 to 2016. We grouped the patients into four groups. Group 1 (n= 297) included patients with BMI< 40 Kg/m2 treated with NOACs, Group 2 (n= 358) included patients on warfarin with BMI< 40 Kg/m2, Group 3 (n= 57) had patients on NOACs with BMI≥ 40 Kg/m2 and Group 4 (n= 43) included patients on warfarin and BMI≥ 40 Kg/m2. Study outcomes were the composite endpoint of stroke, bleeding, and survival. Results: Competing risk regression showed that stroke and bleeding were not affected by obesity or treatment (SHR: 1.09 (95% CI: 0.79- 1.51); P= 0.62). Older age was the predictor of stroke/bleeding (HR:1.03 (95% CI:1.01- 1.06); P= 0.02). Predictors of mortality were heart failure (HR:2.23 (95% CI:1.25- 3.97); P= 0.007), lower creatinine clearance (HR: 0.98 (95% CI:0.97- 0.98): P< 0.001), non-obese patients on warfarin (HR:3.51 (95%CI:1.6- 7.7): P=0.002) and obese patients on warfarin (HR: 6.7 (95% CI:2.51- 17.92); P< 0.001). Conclusion: NOACs could have a similar risk profile to warfarin in obese and non-obese patients with non-valvular AF but could have better survival. Larger randomized trials are recommended.
