Characterization And Clinical Significance Of Eif1ax Mutations And Co-Mutations In Cytologically Indeterminate Thyroid Nodules: A 5-Year Retrospective Analysis., Stacey Gargano, Nitika Badjatia, Yanina Nikolaus, Stephen C Peiper, Zi-Xuan Wang, Phd

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

OBJECTIVE: Mutations in the EIF1AX gene have been recently detected in a small percentage of benign and malignant thyroid lesions. We sought to investigate the prevalence and clinical significance of EIF1AX mutations and co-mutations in cytologically indeterminate thyroid nodules at our institution.

MATERIALS AND METHODS: A 5-year retrospective analysis was performed on thyroid nodules with a cytologic diagnosis of Bethesda category III or IV, which had undergone testing by our in-house next generation sequencing panel. Surgically resected nodules with EIF1AX mutations were identified, and mutation type and presence of co-mutations were correlated with histopathologic diagnosis.

RESULTS: 41/904 (4.5%) cases overall …

Neurophysiology Of Space Medicine: A Literature Review, Jose R. Velasquez

MEDI 9331 Scholarly Activities Clinical Years

Space medicine is becoming an essential and expanding clinical discipline. Acquiring a deeper and complete picture understanding of the multi-systemic response due to space on human health and function is essential to ensure the success of future space exploration. A comprehensive review of the literature was performed using PubMed and focused on the current neurophysiologic findings of the central nervous system’s response to space. Ground-based analogues, which mimic the effects of microgravity, and actual spaceflight studies have been used to analyze these physiologic adaptations to space. Overall, cerebellar, sensorimotor and vestibular brain regions seem to be affected the most. Through …

Bnst Specific Mglu5 Receptor Knockdown Regulates Sex-Dependent Expression Of Negative Affect Produced By Adolescent Ethanol Exposure And Adult Stress, Chelsea R. Kasten, Eleanor B. Holmgren, Mollie R. Lerner, Tiffany A. Wills

School of Medicine Faculty Publications

Adolescent alcohol use is one of the strongest predictors for the development of an alcohol use disorder (AUD). Notably, this period of risk coincides with the development of affective disorders, which disproportionately impact and drive problematic drinking behavior in women. Stress is a particularly salient factor that drives relapse during periods of abstinence. Previous work in our lab has shown that adolescent intermittent ethanol vapor (AIE) produces sex-dependent changes in glutamatergic activity in the bed nucleus of the stria terminalis (BNST) and behavioral outcomes following acute restraint stress in adulthood. In females, AIE disrupts group 1 metabotropic glutamate (mGlu1/5) receptor …

Esophageal Cancer Complicated By A Distal Acquired Esophagopulmonary Fistula, Alexander D. Lake, Yousef Almuzaini, Aaron Jaffe, Joseph Staffetti, Mukesh Patel

HCA Healthcare Journal of Medicine

Esophageal respiratory fistulas, commonly found as a tracheoesophageal fistula (TEF), are abnormal connections between the esophagus and trachea. These can be congenital (infants) or acquired (malignancy). A more rare form of an esophageal respiratory fistula is an abnormal connection between the esophagus and the lung parenchyma—also known as an esophagopulmonary fistula. In our case, we present a middle-aged male with a history of esophageal cancer undergoing chemotherapy and radiation presenting into the intensive care unit for increasing shortness of breath and vomiting after eating found to have a rare form of a TEF causing his symptoms.

There is substantial experimental evidence for dysregulation of several microRNA (miRNA) expression levels in Alzheimer’s disease (AD). MiRNAs modulate critical brain intracellular signaling pathways and are associated with AD core pathophysiological mechanisms. First, we conducted a real-time quantitative PCR-based pilot study to identify a set of brain-enriched miRNAs in a monocentric cohort of cognitively normal individuals with subjective memory complaints, a condition associated with increased risk of AD. Second, we investigated the impact of age, sex, and the Apolipoprotein E ε4 (APOE ε4) allele, on the identified miRNA plasma concentrations. In addition, we explored the cross-sectional and longitudinal association of …

Clinical Performance Of The Point-Of-Care Cobas Liat For Detection Of Sars-Cov-2 In 20 Minutes: A Multicenter Study., Glen Hansen, Jamie Marino, Zi-Xuan Wang, Kathleen G Beavis, John Rodrigo, Kylie Labog, Lars F Westblade, Run Jin, Nedra Love, Karen Ding, Sachin Garg, Alan Huang, Joanna Sickler, Nam K Tran

Highly accurate testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) at the point of care (POC) is an unmet diagnostic need in emergency care and time-sensitive outpatient care settings. Reverse transcription-PCR (RT-PCR) technology is the gold standard for SARS-CoV-2 diagnostics. We performed a multisite U.S. study comparing the clinical performance of the first U.S. Food and Drug Administration (FDA)-authorized POC RT-PCR for detection of SARS-CoV-2 in 20 min, the cobas Liat SARS-CoV-2 and influenza A/B nucleic acid test, to the most widely used RT-PCR laboratory test, the cobas 68/8800 SARS-CoV-2 test. Clinical nasopharyngeal swab specimens from 444 patients with …

Fgdb: Database Of Follicle Stimulating Hormone Glycans, Sushil Kumar Shakyawar, Sanjit Pandey, David J. Harvey, George Bousfield, Chittibabu Guda

Journal Articles: Genetics, Cell Biology & Anatomy

Glycomics, the study of the entire complement of sugars of an organism has received significant attention in the recent past due to the advances made in high throughput mass spectrometry technologies. These analytical advancements have facilitated the characterization of glycans associated with the follicle-stimulating hormones (FSH), which play a central role in the human reproductive system both in males and females utilizing regulating gonadal (testicular and ovarian) functions. The irregularities in FSH activity are also directly linked with osteoporosis. The glycoanalytical studies have been tremendously helpful in understanding the biological roles of FSH. Subsequently, the increasing number of characterized FSH …

Effect Of Eurycoma Longifolia And Eccentric Exercise On Quadriceps Strength In Elite Rugby Player, Ahmad Zawawi Zakaria

Student Works (2020-2029)

Optimizing performance by resistance training over a limited amount of time was imperative in a training year plan. Superior effect of eccentric training has been documented but less known its influence on elite athletes which incorporated submaximal and supramaximal intensity eccentric that was essential for muscle strength and hypertrophy. Correspondingly, Eurycoma longifolia Jack (ElJ) supplementation has been shown to stimulate the production of the non-prohibited androgenic hormones, which was important for athletic performance in terms of muscular strength and size. However, investigation was not sufficiently vigorous on such effect of a supplement in elite athletes. Therefore, the major aim of …
