Reliability And Validity Of Smartphone Cognitive Testing For Frontotemporal Lobar Degeneration, Adam M Staffaroni, Nupur Ghoshal, Jason Hassenstab, Et Al.

2020-Current year OA Pubs

IMPORTANCE: Frontotemporal lobar degeneration (FTLD) is relatively rare, behavioral and motor symptoms increase travel burden, and standard neuropsychological tests are not sensitive to early-stage disease. Remote smartphone-based cognitive assessments could mitigate these barriers to trial recruitment and success, but no such tools are validated for FTLD.

OBJECTIVE: To evaluate the reliability and validity of smartphone-based cognitive measures for remote FTLD evaluations.

DESIGN, SETTING, AND PARTICIPANTS: In this cohort study conducted from January 10, 2019, to July 31, 2023, controls and participants with FTLD performed smartphone application (app)-based executive functioning tasks and an associative memory task 3 times over 2 weeks. …

A Protective Role For Type I Interferon Signaling Following Infection With Mycobacterium Tuberculosis Carrying The Rifampicin Drug Resistance-Conferring Rpob Mutation H445y, Suhas Bobba, Kuldeep S. Chauhan, Sadia Akter, Shibali Das, Ekansh Mittal, Barun Mathema, Jennifer A. Philips, Shabaana A. Khader

2020-Current year OA Pubs

Interleukin-1 (IL-1) signaling is essential for controlling virulent Mycobacterium tuberculosis (Mtb) infection since antagonism of this pathway leads to exacerbated pathology and increased susceptibility. In contrast, the triggering of type I interferon (IFN) signaling is associated with the progression of tuberculosis (TB) disease and linked with negative regulation of IL-1 signaling. However, mice lacking IL-1 signaling can control Mtb infection if infected with an Mtb strain carrying the rifampin-resistance conferring mutation H445Y in its RNA polymerase β subunit (rpoB-H445Y Mtb). The mechanisms that govern protection in the absence of IL-1 signaling during rpoB-H445Y Mtb infection are unknown. In this study, …

Enhancing Impact: A Call To Action For Equitable Implementation Science, Rachel C Shelton, Ross C Brownson

2020-Current year OA Pubs

Despite investments in evidence-based interventions and Implementation Science, most evidence-based interventions are not widely or routinely adopted, delivered, or sustained in many real-world community and healthcare settings. This gap is even greater in settings and populations experiencing numerous social and structural barriers to health, with important implications for persistent patterns in health inequities. In this Viewpoint, as part of a Special Issue on Advancing the Adaptability of Chronic Disease Prevention and Management through Implementation Science, we outline seven calls to action for the field of Implementation Science, with the goal of encouraging researchers, practitioners, and funders to be more intentional …

Adipose Tissue Peroxisomal Lipid Synthesis Orchestrates Obesity And Insulin Resistance Through Lxr-Dependent Lipogenesis, Brian Kleiboeker, Anyuan He, Min Tan, Dongliang Lu, Donghua Hu, Xuejing Liu, Parniyan Goodarzi, Fong-Fu Hsu, Babak Razani, Clay F Semenkovich, Irfan J Lodhi

2020-Current year OA Pubs

OBJECTIVE: Adipose tissue mass is maintained by a balance between lipolysis and lipid storage. The contribution of adipose tissue lipogenesis to fat mass, especially in the setting of high-fat feeding, is considered minor. Here we investigated the effect of adipose-specific inactivation of the peroxisomal lipid synthetic protein PexRAP on fatty acid synthase (FASN)-mediated lipogenesis and its impact on adiposity and metabolic homeostasis.

METHODS: To explore the role of PexRAP in adipose tissue, we metabolically phenotyped mice with adipose-specific knockout of PexRAP. Bulk RNA sequencing was used to determine transcriptomic responses to PexRAP deletion and

RESULTS: Adipose-specific PexRAP deletion promoted diet-induced …

Neurosteroids And Their Potential As A Safer Class Of General Anesthetics, Hiroki Tateiwa, Alex S Evers

2020-Current year OA Pubs

Neurosteroids (NS) are a class of steroids that are synthesized within the central nervous system (CNS). Various NS can either enhance or inhibit CNS excitability and they play important biological roles in brain development, brain function and as mediators of mood. One class of NS, 3α-hydroxy-pregnane steroids such as allopregnanolone (AlloP) or pregnanolone (Preg), inhibits neuronal excitability; these endogenous NS and their analogues have been therapeutically applied as anti-depressants, anti-epileptics and general anesthetics. While NS have many favorable properties as anesthetics (e.g. rapid onset, rapid recovery, minimal cardiorespiratory depression, neuroprotection), they are not currently in clinical use, largely due to …

Pyridoxine Challenge Reflects Pediatric Hypophosphatasia Severity And Thereby Examines Tissue-Nonspecific Alkaline Phosphatase's Role In Vitamin B6 Metabolism, Michael P Whyte, Fan Zhang, Karen E Mack, Deborah Wenkert, Gary S Gottesman, Karen L Ericson, Jeffrey T Cole, Stephen P Coburn

2020-Current year OA Pubs

Alkaline phosphatase (ALP) is detected in most human tissues. However, ALP activity is routinely assayed using high concentrations of artificial colorimetric substrates in phosphate-free laboratory buffers at lethal pH. Hypophosphatasia (HPP) is the inborn-error-of-metabolism caused by loss-of-function mutation(s) of the ALPL gene that encodes the ALP isoenzyme expressed in bone, liver, kidney, and elsewhere and is therefore designated "tissue-nonspecific" ALP (TNSALP). Consequently, HPP harbors clues concerning the biological function of this phosphohydrolase that is anchored onto the surface of cells. The biochemical signature of HPP features low serum ALP activity (hypophosphatasemia) together with elevated plasma levels of three natural substrates …

Who's Essential Medicines And Aware: Recommendations On First- And Second-Choice Antibiotics For Empiric Treatment Of Clinical Infections, Lorenzo Moja, Sumanth Gandra, Et Al.

2020-Current year OA Pubs

The WHO Model List of Essential Medicines (EML) prioritizes medicines that have significant global public health value. The EML can also deliver important messages on appropriate medicine use. Since 2017, in response to the growing challenge of antimicrobial resistance, antibiotics on the EML have been reviewed and categorized into three groups: Access, Watch, and Reserve, leading to a new categorization called AWaRe. These categories were developed taking into account the impact of different antibiotics and classes on antimicrobial resistance and the implications for their appropriate use. The 2023 AWaRe classification provides empirical guidance on 41 essential antibiotics for over 30 …

2020-Current year OA Pubs

Altered apolipoprotein kinetics play a critical role in promoting dyslipidemia and atherogenesis. Human apolipoprotein kinetics have been extensively evaluated, but similar studies in mice are hampered by the lack of robust methods suitable for the small amounts of blood that can be collected at sequential time points from individual mice. We describe a targeted liquid chromatography tandem mass spectrometry method for simultaneously quantifying the stable isotope enrichment of several apolipoproteins represented by multiple peptides in serial blood samples (15 μl each) obtained after retro-orbital injection of

Early Treatment With Fluvoxamine, Bromhexine, Cyproheptadine, And Niclosamide To Prevent Clinical Deterioration In Patients With Symptomatic Covid-19: A Randomized Clinical Trial, Dhammika Leshan Wannigama, Angela M Reiersen, Et Al.

2020-Current year OA Pubs

BACKGROUND: Repurposed drugs with host-directed antiviral and immunomodulatory properties have shown promise in the treatment of COVID-19, but few trials have studied combinations of these agents. The aim of this trial was to assess the effectiveness of affordable, widely available, repurposed drugs used in combination for treatment of COVID-19, which may be particularly relevant to low-resource countries.

METHODS: We conducted an open-label, randomized, outpatient, controlled trial in Thailand from October 1, 2021, to June 21, 2022, to assess whether early treatment within 48-h of symptoms onset with combinations of fluvoxamine, bromhexine, cyproheptadine, and niclosamide, given to adults with confirmed mild …

T-Cell Acute Lymphoblastic Leukemia/Lymphoma (T-All) With Negative Screening Immaturity Markers And Gamma-Delta Receptor Expression, Maria Faraz, Anita Parmigiani, Nina Monkash, Anne Chen

2020-Current year OA Pubs

T-cell acute lymphoblastic leukemia/lymphoma (T-ALL) is characterized by the combination of T-cell lineage and the presence of immaturity marker(s). Sometimes, the most common immaturity markers for initial flow cytometry screening in T-ALL may be negative, which can be a diagnostic pitfall. When a lack of common first-line immaturity markers is encountered in combination with gamma/delta T-cell receptor expression, a misdiagnosis of mature gamma-delta T-cell leukemia/lymphoma could be rendered. Here, we discuss two T-ALL cases with the absence of common flow cytometry immaturity markers and positive gamma/delta receptor expression.

Threat Experiences Moderate The Link Between Hippocampus Volume And Depression Symptoms Prospectively In Adolescence, Max P Herzberg, Meriah L Dejoseph, Joan Luby, Deanna M Barch

2020-Current year OA Pubs

Identifying neuroimaging risk markers for depression has been an elusive goal in psychopathology research. Despite this, smaller hippocampal volume has emerged as a potential risk marker for depression, with recent research suggesting this association is moderated by family income. The current pre-registered study aimed to replicate and extend these findings by examining the moderating role of family income and three dimensions of environmental experience on the link between hippocampus volume and later depression. Data were drawn from the Adolescent Brain Cognitive Development (ABCD) study and were comprised of 6693 youth aged 9-10 years at baseline. Results indicated that psychosocial threat …

The Impact Of Individual-Level Income Predicted From The Brfss On The Association Between Insurance Status And Overall Survival Among Adults With Cancer From The Seer Program, Justin M Barnes, Kimberly J Johnson, Nosayaba Osazuwa-Peters, Matthew B Spraker

2020-Current year OA Pubs

INTRODUCTION: Among patients with cancer in the United States, Medicaid insurance is associated with worse outcomes than private insurance and with similar outcomes as being uninsured. However, prior studies have not addressed the impact of individual-level socioeconomic status, which determines Medicaid eligibility, on the associations of Medicaid status and cancer outcomes. Our objective was to determine whether differences in cancer outcomes by insurance status persist after accounting for individual-level income.

METHODS: The Surveillance, Epidemiology, and End Results (SEER) database was queried for 18-64 year-old individuals with cancer from 2014-2016. Individual-level income was imputed using a model trained on Behavioral Risk …

Microbiota-directed complementary food (MDCF) formulations have been designed to repair the gut communities of malnourished children. A randomized controlled trial demonstrated that one formulation, MDCF-2, improved weight gain in malnourished Bangladeshi children compared to a more calorically dense standard nutritional intervention. Metagenome-assembled genomes from study participants revealed a correlation between ponderal growth and expression of MDCF-2 glycan utilization pathways by Prevotella copri strains. To test this correlation, here we use gnotobiotic mice colonized with defined consortia of age- and ponderal growth-associated gut bacterial strains, with or without P. copri isolates closely matching the metagenome-assembled genomes. Combining gut metagenomics and metatranscriptomics …

Exploring The Association Between Weight Loss-Inducing Medications And Multiple Sclerosis: Insights From The Fda Adverse Event Reporting System Database, Afsaneh Shirani, Anne H Cross, Olaf Stuve

2020-Current year OA Pubs

BACKGROUND: Several studies have demonstrated that early childhood and adolescent obesity are risk factors for multiple sclerosis (MS) susceptibility. Obesity is thought to share inflammatory components with MS through overproduction of pro-inflammatory adipokines (e.g., leptin) and reduction of anti-inflammatory adipokines (e.g, adiponectin). Recently, drug repurposing (i.e. identifying new indications for existing drugs) has garnered significant attention. The US Food and Drug Administration Adverse Event Reporting System (FAERS) database serves not only as a resource for mining adverse drug reactions and safety signals but also for identifying inverse associations and potential medication repurposing opportunities.

OBJECTIVE: We aimed to explore the association …

Anatomical Registration Of Intracranial Electrodes. Robust Model-Based Localization And Deformable Smooth Brain-Shift Compensation Methods, Alejandro Omar Blenkmann, Sabine Liliana Leske, Anaïs Llorens, Jack J Lin, Edward F Chang, Peter Brunner, Gerwin Schalk, Jugoslav Ivanovic, Pål Gunnar Larsson, Robert Thomas Knight, Tor Endestad, Anne-Kristin Solbakk

2020-Current year OA Pubs

BACKGROUND: Intracranial electrodes are typically localized from post-implantation CT artifacts. Automatic algorithms localizing low signal-to-noise ratio artifacts and high-density electrode arrays are missing. Additionally, implantation of grids/strips introduces brain deformations, resulting in registration errors when fusing post-implantation CT and pre-implantation MR images. Brain-shift compensation methods project electrode coordinates to cortex, but either fail to produce smooth solutions or do not account for brain deformations.

NEW METHODS: We first introduce GridFit, a model-based fitting approach that simultaneously localizes all electrodes' CT artifacts in grids, strips, or depth arrays. Second, we present CEPA, a brain-shift compensation algorithm combining orthogonal-based projections, spring-mesh models, …

2020-Current year OA Pubs

Persistent immune activation contributes significantly to left ventricular (LV) dysfunction and adverse remodeling in heart failure (HF). In contrast to their well-known essential role in acute myocardial infarction (MI) as first responders that clear dead cells and facilitate subsequent reparative macrophage polarization, the role of neutrophils in the pathobiology of chronic ischemic HF is poorly defined. To determine the importance of neutrophils in the progression of ischemic cardiomyopathy, we measured their production, levels, and activation in a mouse model of chronic HF 8 weeks after permanent coronary artery ligation and large MI. In HF mice, neutrophils were more abundant both …
