INTRODUCTION: The Institute for Implementation Science Scholars (IS-2) is a dissemination and implementation (D&I) science training and mentoring program. A key component of IS-2 is collaborating and networking. To build knowledge on effective networking and mentoring, this study sought to 1) conduct a social network analysis to determine whether underrepresented scholars have equivalent levels of connection and 2) gain insights into the differences in networking among racial/ethnic subgroups of scholars.

METHODS: Social network survey data were used to select participants based on number of collaborative connections (highest, lowest) and racial/ ethnic category (underrepresented, not underrepresented). Interviews were recorded, transcribed, and …

The Foundational Capabilities Of Large Language Models In Predicting Postoperative Risks Using Clinical Notes, Charles Alba, Bing Xue, Joanna Abraham, Thomas Kannampallil, Chenyang Lu

2020-Current year OA Pubs

Clinical notes recorded during a patient's perioperative journey holds immense informational value. Advances in large language models (LLMs) offer opportunities for bridging this gap. Using 84,875 preoperative notes and its associated surgical cases from 2018 to 2021, we examine the performance of LLMs in predicting six postoperative risks using various fine-tuning strategies. Pretrained LLMs outperformed traditional word embeddings by an absolute AUROC of 38.3% and AUPRC of 33.2%. Self-supervised fine-tuning further improved performance by 3.2% and 1.5%. Incorporating labels into training further increased AUROC by 1.8% and AUPRC by 2%. The highest performance was achieved with a unified foundation model, …

Protein aggregates are emerging therapeutic targets in rare monogenic causes of cardiomyopathy and amyloid heart disease, but their role in more prevalent heart-failure syndromes remains mechanistically unexamined. We observed mislocalization of desmin and sarcomeric proteins to aggregates in human myocardium with ischemic cardiomyopathy and in mouse hearts with post-myocardial infarction ventricular remodeling, mimicking findings of autosomal-dominant cardiomyopathy induced by the R120G mutation in the cognate chaperone protein CRYAB. In both syndromes, we demonstrate increased partitioning of CRYAB phosphorylated on serine 59 to NP40-insoluble aggregate-rich biochemical fraction. While CRYAB undergoes phase separation to form condensates, the phosphomimetic mutation of serine 59 …

Assessing Dynamic Cognitive Function In The Daily Lives Of Youths With And Without Type 1 Diabetes: Usability Study, Mary Katherine Ray, Jorie Fleming, Andrew Aschenbrenner, Jason Hassenstab, Brooke Redwine, Carissa Burns, Ana Maria Arbelaez, Mary Ellen Vajravelu, Tamara Hershey

2020-Current year OA Pubs

BACKGROUND: Studies have shown a relationship between worse glycemic control and lower cognitive scores in youths with type 1 diabetes (T1D). However, most studies assess long-term glucose control (eg, years-decades) and cognition at a single time point. Understanding this relationship at a higher temporal resolution (eg, minutes-hours) and in naturalistic settings has potential clinical implications. Newer technology (eg, continuous glucose monitoring [CGM] and ecological momentary assessment) provides a unique opportunity to explore the glucose dynamics that influence dynamic cognition; that is, cognitive functions that fluctuate short-term and are influenced by environmental factors.

OBJECTIVE: Before we can assess this relationship, we …

How the brain encodes, recognizes, and memorizes general visual objects is a fundamental question in neuroscience. Here, we investigated the neural processes underlying visual object perception and memory by recording from 3173 single neurons in the human amygdala and hippocampus across four experiments. We employed both passive-viewing and recognition memory tasks involving a diverse range of naturalistic object stimuli. Our findings reveal a region-based feature code for general objects, where neurons exhibit receptive fields in the high-level visual feature space. This code can be validated by independent new stimuli and replicated across all experiments, including fixation-based analyses with large natural …

OBJECTIVE: Obesity is a major risk factor for endometrial cancer. In addition to hormone therapy with progestins, glucagon like peptide-1 receptor (GLP-1R) agonists such as semaglutide may be helpful to achieve weight loss during conservative treatment of endometrial hyperplasia or cancer.

METHODS: We theorized that the combination of semaglutide and the progestin levonorgestrel would be useful as a novel treatment or prevention regimen and tested this hypothesis using endometrial cancer cell lines and patient-derived organoids (PDOs).

RESULTS: Hec50, KLE, and Ishikawa endometrial cancer cells express GLP-1R, as determined by both qPCR and Western blotting, and GLP-1R agonist treatment induces GLP-1R …

Cimpact-Now Update 8: Clarifications On Molecular Risk Parameters And Recommendations For Who Grading Of Meningiomas, Felix Sahm, Sonika Dahiya, Et Al.

2020-Current year OA Pubs

Meningiomas are the most frequent primary intracranial tumors. Hence, they constitute a major share of diagnostic specimens in neuropathology practice. The 2021 WHO Classification of Central Nervous System Tumors ("CNS5") has introduced the first molecular grading parameters for meningioma with oncogenic variants in the TERT promoter and homozygous deletion of CDKN2A/B as markers for CNS WHO grade 3. However, after the publication of the new classification volume, clarifications were requested, not only on novel but also on long-standing questions in meningioma grading that were beyond the scope of the WHO "blue book." In addition, more recent research into possible new …

Lifespan In Rodents With Myt1l Heterozygous Mutation, Allyson Schreiber, Raylynn G Swift, Leslie Wilson, Kristen L Kroll, Joseph D Dougherty, Susan E Maloney

2020-Current year OA Pubs

MYT1L syndrome is a newly recognized disorder characterized by intellectual disability, speech and motor delay, neuroendocrine disruptions, ADHD, and autism. In order to study this gene and its association with these phenotypes, our lab recently created a Myt1l heterozygous mutant mouse inspired by a clinically relevant mutation. This model recapitulates several of the physical and neurologic abnormalities seen in humans with MYT1L syndrome, such as weight gain, microcephaly, and behavioral disruptions. The majority of patients with this syndrome are young, and little is known about the impact of age on health and mortality in these patients. Using a Myt1l mutant …

A Synthetic Chronogenetic Gene Circuit For Programmed Circadian Drug Delivery, Lara Pferdehirt, Anna R Damato, Kristin L Lenz, Maria F Gonzalez-Aponte, Daniel Palmer, Qing-Jun Meng, Erik D Herzog, Farshid Guilak

2020-Current year OA Pubs

Circadian medicine, the delivery of therapeutic interventions based on an individual's daily rhythms, has shown improved efficacy and reduced side-effects for various treatments. Rheumatoid arthritis and other inflammatory diseases are characterized by diurnal changes in cytokines, leading to inflammatory flares, with peak disease activity in the early morning. Using a combination of synthetic biology and tissue engineering, we developed circadian-based gene circuits, termed "chronogenetics", that express a prescribed transgene downstream of the core clock gene promoter, Period2 (Per2). Gene circuits were transduced into induced pluripotent stem cells that were tissue-engineered into cartilage constructs. Our anti-inflammatory chronogenetic constructs produced therapeutic concentrations …

The Tetracycline Resistome Is Shaped By Selection For Specific Resistance Mechanisms By Each Antibiotic Generation, Kevin S Blake, Yao-Peng Xue, Vincent J Gillespie, Skye R S Fishbein, Niraj H Tolia, Timothy A Wencewicz, Gautam Dantas

2020-Current year OA Pubs

The history of clinical resistance to tetracycline antibiotics is characterized by cycles whereby the deployment of a new generation of drug molecules is quickly followed by the discovery of a new mechanism of resistance. This suggests mechanism-specific selection by each tetracycline generation; however, the evolutionary dynamics of this remain unclear. Here, we evaluate 24 recombinant Escherichia coli strains expressing tetracycline resistance genes from each mechanism (efflux pumps, ribosomal protection proteins, and enzymatic inactivation) in the context of each tetracycline generation. We employ a high-throughput barcode sequencing protocol that can discriminate between strains in mixed culture and quantify their relative abundances. …

Bacterial Community Assembly Of Specific Pathogen-Free Neonatal Mice, Elizabeth A Kennedy, James S Weagley, Andrew H Kim, Avan Antia, Anna L Deveaux, Megan T Baldridge

2020-Current year OA Pubs

BACKGROUND: Neonatal mice are frequently used to model diseases that affect human infants. Microbial community composition has been shown to impact disease progression in these models. Despite this, the maturation of the early-life murine microbiome has not been well-characterized. We address this gap by characterizing the assembly of the bacterial microbiota of C57BL/6 and BALB/c litters from birth to adulthood across multiple independent litters.

RESULTS: The fecal microbiome of young pups is dominated by only a few pioneering bacterial taxa. These taxa are present at low levels in the microbiota of multiple maternal body sites, precluding a clear identification of …

Heterogeneous Clinical Phenotypes Of Sporadic Early-Onset Alzheimer's Disease: A Neuropsychological Data-Driven Approach, Deepti Putcha, Erik Musiek, Kyle Womack, Et Al.

2020-Current year OA Pubs

BACKGROUND: The clinical presentations of early-onset Alzheimer's disease (EOAD) and late-onset Alzheimer's disease are distinct, with EOAD having a more aggressive disease course with greater heterogeneity. Recent publications from the Longitudinal Early-Onset Alzheimer's Disease Study (LEADS) described EOAD as predominantly amnestic, though this phenotypic description was based solely on clinical judgment. To better understand the phenotypic range of EOAD presentation, we applied a neuropsychological data-driven method to subtype the LEADS cohort.

METHODS: Neuropsychological test performance from 169 amyloid-positive EOAD participants were analyzed. Education-corrected normative comparisons were made using a sample of 98 cognitively normal participants. Comparing the relative levels of …

Advancing Mitochondrial Therapeutics: Synthesis And Pharmacological Evaluation Of Pyrazole-Based Inhibitors Targeting The Mitochondrial Pyruvate Carrier, Lingaiah Maram, Jessica M Michael, Henry Politte, Vaishnavi S Srirama, Aymen Hadji, Mohammad Habibi, Meredith O Kelly, Rita T Brookheart, Brian N Finck, Lamees Hegazy, Kyle S Mccommis, Bahaa Elgendy

2020-Current year OA Pubs

Inhibition of mitochondrial pyruvate transport via the mitochondrial pyruvate carrier (MPC) has shown beneficial effects in treating metabolic diseases, certain cancers, various forms of neurodegeneration, and hair loss. These benefits arise either from the direct inhibition of mitochondrial pyruvate metabolism or from the metabolic rewiring when pyruvate entry is inhibited. However, current MPC inhibitors are either nonspecific or possess poor pharmacokinetic properties. To address this, approximately 50 pyrazole-based MPC inhibitors were synthesized to explore the structure-activity relationship for MPC inhibition, evaluated through inhibition of mitochondrial pyruvate respiration. These inhibitors were designed with increased steric hindrance around electron-deficient double bonds, allowing …

Sleep-Wake Variation In Body Temperature Regulates Tau Secretion And Correlates With Csf And Plasma Tau, Geoffrey Canet, Brendan P. Lucey, Et Al.

2020-Current year OA Pubs

Sleep disturbance is bidirectionally associated with an increased risk of Alzheimer's disease and other tauopathies. While the sleep-wake cycle regulates interstitial and cerebrospinal fluid (CSF) tau levels, the underlying mechanisms remain unknown. Understanding these mechanisms is crucial, given the evidence that tau pathology spreads through neuron-to-neuron transfer, involving the secretion and internalization of pathological tau forms. Here, we combined in vitro, in vivo, and clinical methods to reveal a pathway by which changes in body temperature (BT) over the sleep-wake cycle modulate extracellular tau levels. In mice, a higher BT during wakefulness and sleep deprivation increased CSF and plasma tau …

The standard-of-care treatment of locally advanced cervical cancer includes pelvic radiation therapy with concurrent cisplatin-based chemotherapy and is associated with a 30%-50% failure rate. New prognostic and therapeutic targets are needed to improve clinical outcomes. The vaginal microbiome has been linked to the pathogenesis of cervical cancer, but little is known about the vaginal microbiome in locally advanced cervical cancer as it relates to chemoradiation. In this pilot study, we utilized 16S rRNA gene community profiling to characterize the vaginal microbiomes of 26 postmenopausal women with locally advanced cervical cancer receiving chemoradiation. Our analysis revealed diverse anaerobe-dominated communities whose taxonomic …

Retinoic Acid Antagonizes Estrogen Signaling To Maintain Adult Uterine Cell Fate, Yan Yin, Meade Haller, Lauren Goldinger, Shivani Bharadwaj, Emily So, Vivian Robles-Pinos, David Chen, Liang Ma

2020-Current year OA Pubs

Classical tissue recombination experiments demonstrate that cell-fate determination along the anterior-posterior axis of the Müllerian duct occurs prior to postnatal day 7 in mice. However, little is known about how these cell types are maintained in adults. In this study, we provide genetic evidence that a balance between antagonistic retinoic acid (RA) and estrogen signaling activity is required to maintain simple columnar cell fate in adult uterine epithelium. Transdifferentiation of simple columnar uterine epithelium into stratified cervicovaginal-like epithelium was observed in three related mouse genetic models, in which RA signaling was perturbed in the postnatal uterus. Single-cell RNA sequencing analysis …

Differential Impact Of Lymphatic Outflow Pathways On Cerebrospinal Fluid Homeostasis, Zachary Papadopoulos, Leon C D Smyth, Igor Smirnov, Daniel A Gibson, Jasmin Herz, Jonathan Kipnis

2020-Current year OA Pubs

Dysfunctional lymphatic drainage from the central nervous system (CNS) has been linked to neuroinflammatory and neurodegenerative disorders, but our understanding of the lymphatic contribution to CNS fluid autoregulation remains limited. Here, we studied forces that drive the outflow of the cerebrospinal fluid (CSF) into the deep and superficial cervical lymph nodes (dcLN and scLN) and tested how the blockade of lymphatic networks affects CNS fluid homeostasis. Outflow to the dcLN occurred spontaneously in the absence of lymphatic pumping and was coupled to intracranial pressure (ICP), whereas scLN drainage was driven by pumping. Impaired dcLN drainage led to elevated CSF outflow …
