Examining The Most Important Risk Factors For Predicting Youth Persistent And Distressing Psychotic-Like Experiences, Nicole R Karcher, Aristeidis Sotiras, Tara A Niendam, Elaine F Walker, Joshua J Jackson, Deanna M Barch

2020-Current year OA Pubs

BACKGROUND: Persistence and distress distinguish more clinically significant psychotic-like experiences (PLEs) from those that are less likely to be associated with impairment and/or need for care. Identifying risk factors that identify clinically relevant PLEs early in development is important for improving our understanding of the etiopathogenesis of these experiences. Machine learning analyses were used to examine the most important baseline factors distinguishing persistent distressing PLEs.

METHODS: Using Adolescent Brain Cognitive Development (ABCD) Study data on PLEs from 3 time points (ages 9-13 years), we created the following groups: individuals with persistent distressing PLEs (n = 305), individuals with transient distressing …

Preliminary Assessment Of Tunic Off-Gassing After Wildland Firefighting Exposure, Kiam Padamsey, Adelle Liebenberg, Ruth Wallace, Jacques Oosthuizen

Research outputs 2022 to 2026

Evidence has previously shown that outer tunics (turnout coats) worn by firefighters at structural fires are contaminated with harmful chemicals which subsequently off-gas from the material. However, there is limited research on whether this phenomenon extends to wildland firefighter uniforms. This pilot study aimed to explore if the tunics of volunteer bushfire and forestry firefighters in Western Australia off-gas any contaminants after exposure to prescribed burns or bushfires, and whether there is a need to explore this further. Nine tunics were collected from firefighters following nine bushfire and prescribed burn events, with a set of unused tunics serving as a …

2020-Current year OA Pubs

BACKGROUND: Observational assessments of infant temperament have provided unparalleled insight into prediction of risk for social anxiety. However, it is challenging to administer and score these assessments alongside high-quality infant neuroimaging data. In the current study, we aimed to identify infant resting-state functional connectivity associated with both parent report and observed behavioral estimates of infant novelty-evoked distress.

METHODS: Using data from the OIT (Origins of Infant Temperament) study, which includes deep phenotyping of infant temperament, we identified parent-report measures that were associated with observed novelty-evoked distress. These parent-report measures were then summarized into a composite score used for imaging analysis. …

Etomoxir-Carnitine, A Novel Pharmaco-Metabolite Of Etomoxir, Inhibits Phospholipases A2 And Mitochondrial Respiration, Sung Ho Moon, Xinping Liu, Christopher M Jenkins, Beverly Gibson Dilthey, Gary J Patti, Richard W Gross

2020-Current year OA Pubs

Mitochondrial fatty acid oxidation serves as an essential process for cellular survival, differentiation, proliferation, and energy metabolism. Numerous studies have utilized etomoxir (ETO) for the irreversible inhibition of carnitine palmitoylcarnitine transferase 1 (CPT1), which catalyzes the rate-limiting step for mitochondrial long-chain fatty acid β-oxidation to examine the bioenergetic roles of mitochondrial fatty acid metabolism in many tissues in multiple diverse disease states. Herein, we demonstrate that intact mitochondria robustly metabolize ETO to etomoxir-carnitine (ETO-carnitine) prior to nearly complete ETO-mediated inhibition of CPT1. The novel pharmaco-metabolite, ETO-carnitine, was conclusively identified by accurate mass, fragmentation patterns, and isotopic fine structure. On the …

2020-Current year OA Pubs

The triggering receptor expressed on myeloid cells-2 (TREM2), a pivotal innate immune receptor, orchestrates functions such as inflammatory responses, phagocytosis, cell survival, and neuroprotection. TREM2 variants R47H and R62H have been associated with Alzheimer's disease, yet the underlying mechanisms remain elusive. Our previous research established that TREM2 binds to heparan sulfate (HS) and variants R47H and R62H exhibit reduced affinity for HS. Building upon this groundwork, our current study delves into the interplay between TREM2 and HS and its impact on microglial function. We confirm TREM2's binding to cell surface HS and demonstrate that TREM2 interacts with HS, forming HS-TREM2 …

Low-Dose Ondansetron: A Candidate Prospective Precision Medicine To Treat Alcohol Use Disorder Endophenotypes, Bankole Johnson, Hannu Alho, Giovanni Addolorato, Otto Michael Lesch, Jonathan Chick, Lei Liu, Vinzant Schuyler

2020-Current year OA Pubs

BACKGROUND: Alcohol use disorder (AUD) is among the leading causes of morbidity and mortality worldwide, and over 95 million people live with alcohol dependence globally. The estimated heritability of AUD is 50-60 %, and multiple genes are thought to contribute to various endophenotypes of the disease. Previous clinical trials support a precision medicine approach using ondansetron (AD04, a 5-HT3 antagonist) by segregating AUD populations by the bio-genetic endophenotype of specific serotonergic genotypes and the bio-psychosocial endophenotype of the severity of drinking or both. By targeting the modulation of biogenetic signaling within the biopsychosocial context of AUD, low-dose AD04 holds promise …

Structure Of A Truncated Human Glcnac-1-Phosphotransferase Variant Reveals The Basis For Its Hyperactivity, Hua Li, Balraj Doray, Benjamin C Jennings, Wang-Sik Lee, Lin Liu, Stuart Kornfeld, Huilin Li

2020-Current year OA Pubs

Mutations that cause loss of function of GlcNAc-1-phosphotransferase (PTase) lead to the lysosomal storage disorder mucolipidosis II. PTase is the key enzyme of the mannose 6-phosphate (M6P) targeting system that is responsible for tagging lysosomal hydrolases with the M6P moiety for their delivery to the lysosome. We had previously generated a truncated hyperactive form of PTase termed S1S3 which was shown to notably increase the phosphorylation level of secreted lysosomal enzymes and enhance their uptake by cells. Here, we report the 3.4 Å cryo-EM structure of soluble S1S3 lacking both transmembrane domains and cytosolic tails. The structure reveals a high …

The Physiologic Basis Of Molecular Therapeutics For Peripheral Nerve Injury: A Primer, Marie C Spezia, Christopher J Dy, David M Brogan

2020-Current year OA Pubs

Peripheral nerve injuries affect a significant number of patients who experience trauma affecting the hand and upper extremity. Improving unsatisfactory outcomes from repair of these injuries remains a clinical challenge despite advancements in microsurgical repair. Imperfections of the nerve regeneration process, including imprecise reinnervation, distal axon degradation, and muscular atrophy, complicate the repair process. However, the capacity for peripheral nerves to regenerate offers an avenue for therapeutic advancement. Regeneration is a temporally and spatially dynamic process coordinated by Schwann cells and neurons among other cell types. Neurotrophic factors are a primary means of controlling cell growth and differentiation in the …

Endogenous Base Damage As A Driver Of Genomic Instability In Homologous Recombination-Deficient Cancers, Lindsey N Aubuchon, Priyanka Verma

2020-Current year OA Pubs

Homologous recombination (HR) is a high-fidelity DNA double-strand break (DSB) repair pathway. Both familial and somatic loss of function mutation(s) in various HR genes predispose to a variety of cancer types, underscoring the importance of error-free repair of DSBs in human physiology. While environmental sources of DSBs have been known, more recent studies have begun to uncover the role of endogenous base damage in leading to these breaks. Base damage repair intermediates often consist of single-strand breaks, which if left unrepaired, can lead to DSBs as the replication fork encounters these lesions. This review summarizes various sources of endogenous base …

Clinical Practice Recommendations For Hematopoietic Cell Transplantation And Cellular Therapies In Follicular Lymphoma: A Collaborative Effort On Behalf Of The American Society For Transplantation And Cellular Therapy And The European Society For Blood And Marrow Transplantation, Madiha Iqbal, Brad S Kahl, Et Al.

2020-Current year OA Pubs

Follicular lymphoma (FL) is the most common indolent B-cell non-Hodgkin lymphoma (NHL), accounting for nearly one-third of all NHL. The therapeutic landscape for patients with FL has significantly expanded over the past decade, but the disease continues to be considered incurable. Hematopoietic cell transplantation (HCT) is potentially curative in some cases. Recently, the emergence of chimeric antigen receptor T-cell therapy (CAR-T) for patients with relapsed/refractory (R/R) FL has yielded impressive response rates and long-term remissions, but definitive statement on the curative potential of CAR-T is currently not possible due to limited patient numbers and relatively short follow up. A consensus …

Tauroursodeoxycholic Acid Ameliorates Renal Injury Induced By Col4a3 Mutation, Shuwen Yu, Teija Suhas, Meei-Hua Lin, Jeffrey H Miner, Et Al.

2020-Current year OA Pubs

COL4A3/A4/A5 mutations have been identified as critical causes of Alport syndrome and other genetic chronic kidney diseases. However, the underlying pathogenesis remains unclear, and specific treatments are lacking. Here, we constructed a transgenic Alport syndrome mouse model by generating a mutation (Col4a3 p.G799R) identified previously from one large Alport syndrome family into mice. We observed that the mutation caused a pathological decrease in intracellular and secreted collagen IV α3α4α5 heterotrimers. The mutant collagen IV α3 chains abnormally accumulated in the endoplasmic reticulum and exhibited defective secretion, leading to persistent endoplasmic reticulum stress in vivo and in vitro. RNA-seq analysis revealed …

A Podcast On Practical Considerations In Patients With Advanced Urothelial Cancer Receiving First-Line Cisplatin- Or Carboplatin-Based Chemotherapy Followed By Avelumab Maintenance In A Changing Therapeutic Landscape, Jun Gong, Melissa A Reimers

2020-Current year OA Pubs

Platinum-based chemotherapy has been the cornerstone of first-line treatment for advanced urothelial carcinoma for decades, based on its proven efficacy and well-characterized safety profile. Although enfortumab vedotin (EV) plus pembrolizumab showed superior efficacy versus platinum-based chemotherapy in the EV-302 phase 3 trial, common and potentially cumulative toxicities associated with EV plus pembrolizumab may make this combination less suitable for some patients, such as those with pre-existing neuropathy, hyperglycemia, or hepatic impairment, or patients likely to have favorable outcomes with platinum-based chemotherapy. The availability of EV plus pembrolizumab in various countries may also be limited by financial considerations. Thus, platinum-based chemotherapy …

Diverse And Multifunctional Roles For Perlecan (Hspg2) In Repair Of The Intervertebral Disc, James Melrose, Farshid Guilak

2020-Current year OA Pubs

Perlecan is a widely distributed, modular, and multifunctional heparan sulfate proteoglycan, which facilitates cellular communication with the extracellular environment to promote tissue development, tissue homeostasis, and optimization of biomechanical tissue functions. Perlecan-mediated osmotic mechanotransduction serves to regulate the metabolic activity of cells in tissues subjected to tension, compression, or shear. Perlecan interacts with a vast array of extracellular matrix (ECM) proteins through which it stabilizes tissues and regulates the proliferation or differentiation of resident cell populations. Here we examine the roles of the HS-proteoglycan perlecan in the normal and destabilized intervertebral disc. The intervertebral disc cell has evolved to survive …

Avoiding The Pitfalls Of The Dsm-5: A Primer For Health Professionals, Darren Haywood, David J. Castle, Nicolas H. Hart

Research outputs 2022 to 2026

The Diagnostic and Statistical Manual of Mental Disorders-5 (DSM-5), is the leading system guiding the diagnosis of mental disorders. Accurate diagnoses of mental disorders are fundamental to guiding treatment and supportive care and have potential impacts on resources available to individuals. However, the DSM has the allure of ‘tick box’ diagnosis rather than biopsychosocial formulation and treatment planning, as well as multiple limitations impacting validity. Further, even with accurate diagnosis, there are strong concerns related to the reliability and validity of DSM diagnoses for clinical practice and research efforts. Understanding these limitations can help reduce errors and sub-optimal clinical decisions, …
