A Review Of Consanguinity In The Iraqi Population: A Call To Action To Prevent A Future Health Catastrophe, Zaid Ali Hawi, Kealan Pugsley, Atefeh Namipashaki, Walied Samarrai, Ziarih Hawi

Publications and Research

Although not uncommon worldwide, consanguinity has been a part of Arab culture and tradition as a means to strengthen tribal blood relations. However, this type of union has been linked to inherited diseases, particularly those of a recessive nature (e.g., hemoglobinopathies). Furthermore, several recent studies have documented highly significant associations between consanguineous parentage and common multifactorial diseases, including but not limited to hypertension, mental disorders, and several cardiovascular diseases. In Iraq, the prevalence of consanguinity is very high and still on the rise. This has resulted in an increased prevalence of inherited diseases and has significant negative impacts on Iraq’s …

Secondary Electrons And Compton X-Ray Generation In Solid And Heated Biological Sample In The Presence Of Radiologic Contrast Media, Vanessa Robinson, Daler Djuraev, Fatima Ahmed

Publications and Research

Our goal is identification of secondary electrons and Compton photons when externally infused radiological contrast from iodine and gadolinium interferes with calcium and iron in tissues. This could help develop next generation of x-ray methods as well as mechanistic understanding of toxic effects of radiology contrast materials on living tissue and agriculture. Changes in tissue minerals over time, aging and heat stress are manipulated in our experiments by infusing imaging contrast agents that consist of large atoms like Gadolinium and Iodine. These have chelation properties to alter electron distribution of proteins and carbohydrates of biological matrix. Our experiments try to …


Implicit Bias Among Health Professionals, Kimora H. Toussaint, Javiela Evangelista Dec 2023

Implicit Bias Among Health Professionals, Kimora H. Toussaint, Javiela Evangelista

Publications and Research

Racism and implicit bias are prevalent in healthcare, which may affect patient well-being. One way implicit bias is most evident is in language. Negative descriptors, such as “sickler”—a term used for those diagnosed with Sickle Cell Disease (SCD), influence how health providers view their patients and determine pain medication prescriptions (Goddu et al.). Patient experience, such as prior use of opioids or using words that imply substance abuse, may block patients from accessing prescriptions and proper care. Black, Indigenous, and People of Color (BIPOC) are disproportionately affected by such negative descriptors (Sun et al., 2022). Among other adverse impacts, treating …


Examining The Evidence Base For Burnout, Renzo Bianchi, Irvin Schonfeld Nov 2023

Examining The Evidence Base For Burnout, Renzo Bianchi, Irvin Schonfeld

Publications and Research

Burnout has elicited growing interest among occupational health specialists in recent decades. Since 2019, the World Health Organization has characterized burnout as a syndrome resulting from chronic, unmanageable workplace stress. Accordingly, three symptoms define the entity: (i) feelings of energy depletion or exhaustion; (ii) increased mental distance from one’s job or feelings of negativism or cynicism towards one’s job; and (iii) a sense of ineffectiveness and lack of accomplishment. We call into question the definition of burnout embodied in the Maslach Burnout Inventory and incorporated into the ICD-11. We draw stakeholders’ attention to the fact that burnout’s symptoms and etiology …

Burnout has elicited growing interest among occupational health specialists in recent decades. Since 2019, the World Health Organization has characterized burnout as a syndrome resulting from chronic, unmanageable workplace stress. According to the ICD-11, three symptoms define the entity: feelings of exhaustion, increased mental distance from one’s job, and a sense of ineffectiveness at work, all of which correspond to the structure of the Maslach Burnout Inventory. The ICD-11 includes burnout among the factors that influence health status. This paper calls into question that conceptualization based on a number of lines of evidence. The evidence includes the following: burnout was …


Insights Into The Molecular Roles Of Foxr2 In The Pathology Of Primary Pediatric Brain Tumors, Rajendra Gharbaran Oct 2023

Insights Into The Molecular Roles Of Foxr2 In The Pathology Of Primary Pediatric Brain Tumors, Rajendra Gharbaran

Publications and Research

Forkhead box gene R2 (FOXR2) belongs to the family of FOX genes which codes for highly conserved transcription factors (TFs) with critical roles in biological processes ranging from development to organogenesis to metabolic and immune regulation to cellular homeostasis. A number of FOX genes are associated with cancer development and progression and poor prognosis. A growing body of evidence suggests that FOXR2 is an oncogene. Studies suggested important roles for FOXR2 in cancer cell growth, metastasis, and drug resistance. Recent studies showed that FOXR2 is overexpressed by a subset of newly identified entities of embryonal tumors. This review discusses the …

Typically, only high field systems are equipped with stronger gradients and short RF pulse designs, a must for high temporal resolution that are also responsible for high SAR, high susceptibility as well as neurostimulation. Gradient induced image noise tends to be high at 3T. Often vendors try to ameliorate such increased image noise with multi-channel head arrays and aggressive filter designs allowing an appearance of high SNR and CNR quality; however, the achievable SNR and CNR in the AVM remain limited as the analyzed articles by Zhuo et al seem to have in common. A short term solution to harvest …

The Pandemic Anxiety Inventory: A Validation Study, Irvin Sam Schonfeld, Tasmyn Prytherch, Mark Cropley, Renzo Bianchi

Publications and Research

The Pandemic Anxiety Inventory (PAI) assesses anxiety symptoms individuals attribute to the presence of a pandemic. We conducted this study of 379 British adults during the COVID-19 pandemic and found that the PAI exhibited excellent reliability and solid criterion validity. Pandemic anxiety was associated with reduced social support, anticipated life changes, financial strain, job loss, economic insecurity, and the hospitalization or death of a close friend or relative. Using correlational and bifactor analyses, we found that the PAI demonstrated solid convergent and discriminant validity. The findings suggest that the PAI can be used in research and clinical practice.

Human Retinal Organoids Release Extracellular Vesicles That Regulate Gene Expression In Target Human Retinal Progenitor Cells, Rajendra Gharbaran

Publications and Research

Introduction: Diabetic Retinopathy (DR) is a potentially blinding retinal disorder that develops through the pathogenesis of diabetes. The lack of disease predictors implies a poor prognosis with frequent irreversible retinal damage and vision loss. Extracellular Vesicles (EVs) present a novel opportunity for pre-symptomatic disease diagnosis and prognosis, both severely limited in DR. All biological fluids contain EVs, which are currently being studied as disease biomarkers. EV proteins derived from urine have emerged as potential noninvasive biomarkers.

Methods: In this study, we isolated EVs from DR retinal tissue explants and from DR patients' urine, and characterized the vesicles, finding differences in …

Standard Deviations Of Mr Signal Intensities Show A Consistent Trend During Imaging Follow-Ups For Glioblastoma Patients When Corrected For Non-Biological Heterogeneity Due To Hardware And Software Variation, Subhendra N. Sarkar, Rafael Rojas, Evans Lespinasse, Xiangfu Zhang, Ruth Zeron

Publications and Research

Introduction

Glioblastoma multiforme (GBM) has a poor prognosis in spite of advanced MRI guided treatments today. Routine MRI using conventional T1 or advanced permeability based MRI of GBM often does not adequately represent changing tumor phases or overall survival. In this work, region of interest (ROI) based tissue MR standard deviation (SD) is demonstrated as an important MRI variable that could be a potential biomarker of GBM heterogeneity and radioresistance.

Materials and methods

MRI characterization is often qualitative and lacks reproducibility. Using standardized MRI phantoms we have normalized retrospective records of 12 radioresistant GBM patients that underwent radiation therapy …

Radiology departments have contributed significantly to greenhouse gases including release of toxic imaging contrast media to environment. We feel Radiology also has several spectroscopy and imaging tools that may apply to monitor and support cleaner environmental goals. The current manuscript is one of the firsts to prompt Radiology to move in that direction by non invasive imaging of bio metals that are less abundant in biological tissues but play key roles as co-factors in tissue structure and function. Conventional analytical tools are mostly invasive and cannot characterize the native oxidation states of bio metals. We chose carbohydrate matrix of metal-rich …
