Additional analyses showed that early transfusion (within 3 days of hospital admission) of …

Bacterial Sepsis Increases Hippocampal Fibrillar Amyloid Plaque Load And Neuroinflammation In A Mouse Model Of Alzheimer's Disease, Jacob M Basak, Aura Ferreiro, Lucy S Cohen, Patrick W Sheehan, Collin J Nadarajah, Michael F Kanan, Kimberley V Sukhum, Gautam Dantas, Erik S Musiek

2020-Current year OA Pubs

BACKGROUND: Sepsis, a leading cause for intensive care unit admissions, causes both an acute encephalopathy and chronic brain dysfunction in survivors. A history of sepsis is also a risk factor for future development of dementia symptoms. Similar neuropathologic changes are associated with the cognitive decline of sepsis and Alzheimer's disease (AD), including neuroinflammation, neuronal death, and synaptic loss. Amyloid plaque pathology is the earliest pathological hallmark of AD, appearing 10 to 20 years prior to cognitive decline, and is present in 30% of people over 65. As sepsis is also more common in older adults, we hypothesized that sepsis might …

Oncolytic Hsv-1 G207 Immunovirotherapy For Pediatric High-Grade Gliomas, Gregory K Friedman, Mohamed S Abdelbaki, Et Al

Open Access Publications

BACKGROUND: Outcomes in children and adolescents with recurrent or progressive high-grade glioma are poor, with a historical median overall survival of 5.6 months. Pediatric high-grade gliomas are largely immunologically silent or "cold," with few tumor-infiltrating lymphocytes. Preclinically, pediatric brain tumors are highly sensitive to oncolytic virotherapy with genetically engineered herpes simplex virus type 1 (HSV-1) G207, which lacks genes essential for replication in normal brain tissue.

METHODS: We conducted a phase 1 trial of G207, which used a 3+3 design with four dose cohorts of children and adolescents with biopsy-confirmed recurrent or progressive supratentorial brain tumors. Patients underwent stereotactic placement …

The health effects of omega-3 fatty acids have been controversial. Here we report the results of a de novo pooled analysis conducted with data from 17 prospective cohort studies examining the associations between blood omega-3 fatty acid levels and risk for all-cause mortality. Over a median of 16 years of follow-up, 15,720 deaths occurred among 42,466 individuals. We found that, after multivariable adjustment for relevant risk factors, risk for death from all causes was significantly lower (by 15-18%, at least p < 0.003) in the highest vs the lowest quintile for circulating long chain (20-22 carbon) omega-3 fatty acids (eicosapentaenoic, docosapentaenoic, and docosahexaenoic acids). Similar relationships were seen for death from cardiovascular disease, cancer and other causes. No associations were seen with the 18-carbon omega-3, alpha-linolenic acid. These findings suggest that higher circulating levels of marine n-3 PUFA are associated with a lower risk of premature death.

Faculty, Staff and Students Publications

BACKGROUND: ATPase family AAA-domain containing protein 3A (ATAD3A) is a nuclear-encoded mitochondrial membrane-anchored protein involved in diverse processes including mitochondrial dynamics, mitochondrial DNA organization, and cholesterol metabolism. Biallelic deletions (null), recessive missense variants (hypomorph), and heterozygous missense variants or duplications (antimorph) in ATAD3A lead to neurological syndromes in humans.

METHODS: To expand the mutational spectrum of ATAD3A variants and to provide functional interpretation of missense alleles in trans to deletion alleles, we performed exome sequencing for identification of single nucleotide variants (SNVs) and copy number variants (CNVs) in ATAD3A in individuals with neurological and mitochondrial phenotypes. A Drosophila Atad3a Gal4 …

Molecular Classification Of A Complex Structural Rearrangement Of The Rb1 Locus In An Infant With Sporadic, Isolated, Intracranial, Sellar Region Retinoblastoma, Kathleen M Schieffer, Margaret Shatara, Et Al.

2020-Current year OA Pubs

Retinoblastoma is a childhood cancer of the retina involving germline or somatic alterations of the RB Transcriptional Corepressor 1 gene, RB1. Rare cases of sellar-suprasellar region retinoblastoma without evidence of ocular or pineal tumors have been described. A nine-month-old male presented with a sellar-suprasellar region mass. Histopathology showed an embryonal tumor with focal Flexner-Wintersteiner-like rosettes and loss of retinoblastoma protein (RB1) expression by immunohistochemistry. DNA array-based methylation profiling confidently classified the tumor as pineoblastoma group A/intracranial retinoblastoma. The patient was subsequently enrolled on an institutional translational cancer research protocol and underwent comprehensive molecular profiling, including paired tumor/normal exome and genome …

Reducing Patient Risk For Suicidal Behaviors With A Safety Bundle Of Best Practices With Non-Psychiatric Patients, Olayemi Akindele

Student Scholarly Projects

Practice Problem: Suicide is a public health condition that affects people globally. The increased suicidal behaviors of patients in a medical-surgical unit demanded an effective screening protocol to identify high-risk patients.

PICOT: In patients 18 years and older on a medical-surgical unit, does the implementation of the Columbia Suicide Severity Rating Scale (C-SSRS) tool and application of a Safety Bundle of Best Practices (SBBP) increase early identification of suicide risk with decreased patient self-harm behaviors, compared to the current standard practice of no assessment tool or safety bundle of best practices within 12 weeks?

Open Access Publications

The role of genetics in the causation of cerebral palsy has become the focus of many studies aiming to unravel the heterogeneous etiology behind this frequent neurodevelopmental disorder. A recent paper reported two unrelated children with a clinical diagnosis of cerebral palsy, who carried the same de novo c.1000G > A (p.Asp334Asn) variant in FBXO31, encoding a widely studied tumor suppressor not previously implicated in monogenic disease. We now identified a third individual with the recurrent FBXO31 de novo missense variant, featuring a spastic-dystonic phenotype. Our data confirm a link between variant FBXO31 and an autosomal dominant neurodevelopmental disorder characterized by …

Germline mutations in BRAF and other components of the MAPK pathway are associated with the congenital syndromes collectively known as RASopathies. Here, we report the association of Septo-Optic Dysplasia (SOD) including hypopituitarism and Cardio-Facio-Cutaneous (CFC) syndrome in patients harbouring mutations in BRAF. Phosphoproteomic analyses demonstrate that these genetic variants are gain-of-function mutations leading to activation of the MAPK pathway. Activation of the MAPK pathway by conditional expression of the Braf^V600E/+ allele, or the knock-in Braf^Q241R/+ allele (corresponding to the most frequent human CFC-causing mutation, BRAF p.Q257R), leads to abnormal cell lineage determination and terminal differentiation of …

Successful Distancing: Telemedicine In Gastroenterology And Hepatology During The Covid-19 Pandemic., Abhilash Perisetti M.B.B.S, M.D., Hemant Goyal

Other Specialties

Telemedicine involves delivering healthcare and preventative care services to patients without the need for in-person encounters. Traditionally, telemedicine has been used for acute events (e.g., stroke, used to relay essential information to the emergency department) and chronic disease management (e.g., diabetes and chronic kidney disease management). Though the utilization of telemedicine in gastroenterology and hepatology has been modest at best, especially for inflammatory bowel diseases and chronic liver disease management, since the onset of coronavirus disease 2019 (COVID-19) pandemic, utilization of telemedicine in gastroenterology increased by 4000% in the first two weeks, equivalent to the last six years of growth …

Mechanisms, Diagnosis, Prevention And Management Of Perioperative Opioid-Induced Hyperalgesia, Sylvia H Wilson, Kevin M Hellman, Dominika James, Adam C Adler, Arvind Chandrakantan

Faculty, Staff and Students Publications

Opioid-induced hyperalgesia (OIH) occurs when opioids paradoxically enhance the pain they are prescribed to ameliorate. To address a lack of perioperative awareness, we present an educational review of clinically relevant aspects of the disorder. Although the mechanisms of OIH are thought to primarily involve medullary descending pathways, it is likely multifactorial with several relevant therapeutic targets. We provide a suggested clinical definition and directions for clinical differentiation of OIH from other diagnoses, as this may be confusing but is germane to appropriate management. Finally, we discuss prevention including patient education and analgesic management choices. As prevention may serve as the …

Loss Of Bone Morphogenetic Protein-Binding Endothelial Regulator Causes Insulin Resistance, Hua Mao, Luge Li, Qiying Fan, Aude Angelini, Pradip K Saha, Huaizhu Wu, Christie M Ballantyne, Sean M Hartig, Liang Xie, Xinchun Pi

Faculty, Staff and Students Publications

Accumulating evidence suggests that chronic inflammation of metabolic tissues plays a causal role in obesity-induced insulin resistance. Yet, how specific endothelial factors impact metabolic tissues remains undefined. Bone morphogenetic protein (BMP)–binding endothelial regulator (BMPER) adapts endothelial cells to inflammatory stress in diverse organ microenvironments. Here, we demonstrate that BMPER is a driver of insulin sensitivity. Both global and endothelial cell-specific inducible knockout of BMPER cause hyperinsulinemia, glucose intolerance and insulin resistance without increasing inflammation in metabolic tissues in mice. BMPER can directly activate insulin signaling, which requires its internalization and interaction with Niemann-Pick C1 (NPC1), an integral membrane protein that …

Beyond Somatosensation: Mrgprs In Mucosal Tissues, Juan M Inclan-Rico, Brian S Kim, Ishmail Abdus-Saboor

2020-Current year OA Pubs

Mas-related G coupled receptors (Mrgprs) are a superfamily of receptors expressed in sensory neurons that are known to transmit somatic sensations from the skin to the central nervous system. Interestingly, Mrgprs have recently been implicated in sensory and motor functions of mucosal-associated neuronal circuits. The gastrointestinal and pulmonary tracts are constantly exposed to noxious stimuli. Therefore, it is likely that neuronal Mrgpr signaling pathways in mucosal tissues, akin to their family members expressed in the skin, might relay messages that alert the host when mucosal tissues are affected by damaging signals. Further, Mrgprs have been proposed to mediate the cross-talk …

Shared Developmental Gait Disruptions Across Two Mouse Models Of Neurodevelopmental Disorders, Rachel M Rahn, Claire T Weichselbaum, David H Gutmann, Joseph D Dougherty, Susan E Maloney

2020-Current year OA Pubs

BACKGROUND: Motor deficits such as abnormal gait are an underappreciated yet characteristic phenotype of many neurodevelopmental disorders (NDDs), including Williams Syndrome (WS) and Neurofibromatosis Type 1 (NF1). Compared to cognitive phenotypes, gait phenotypes are readily and comparably assessed in both humans and model organisms and are controlled by well-defined CNS circuits. Discovery of a common gait phenotype between NDDs might suggest shared cellular and molecular deficits and highlight simple outcome variables to potentially quantify longitudinal treatment efficacy in NDDs.

METHODS: We characterized gait using the DigiGait assay in two different murine NDD models: the complete deletion (CD) mouse, which models …
