METHODS: A scoping review of scientific and grey literature was conducted. A Rapid Assessment Procedure approach guided the design and analysis. Five online scientific bibliographic databases and various Dutch websites were searched …

Her2-Low And Her2-Ultralow Metastatic Breast Cancer And Trastuzumab Deruxtecan: Common Clinical Questions And Answers, Nusayba A Bagegni, Karthik V Giridhar, Daphne Stewart

2020-Current year OA Pubs

Approximately 80% of invasive breast cancers are classified as human epidermal growth factor receptor 2 (HER2)-negative; however, many of these tumors have detectable levels of HER2 surface expression. Trastuzumab deruxtecan (T-DXd) is a HER2-directed antibody-drug conjugate with a membrane-permeable payload that is cytotoxic to both HER2-expressing tumor cells and neighboring cells via the bystander antitumor effect. T-DXd has shown significant antitumor activity in clinical trials for patients with HER2-positive (immunohistochemistry [IHC] 3+ or IHC 2+/in situ hybridization [ISH]+) breast cancer. In addition, the results of the DESTINY-Breast04 trial demonstrated the clinical benefit of T-DXd in patients with HER2-low (IHC 1+ …

Investigating The Polygenic Relationship Between Heavy Cannabis Use And Schizophrenia In The All Of Us Research Program, Isabelle Austin-Zimmerman, Hayley H A Thorpe, John J Meredith, Jibran Y Khokhar, Tian Ge, Marta Di Forti, Arpana Agrawal, Emma C Johnson, Sandra Sanchez-Roige

2020-Current year OA Pubs

BACKGROUND: Decades of research have identified a strong association between heavy cannabis use and schizophrenia (SCZ), with evidence of correlated genetic factors. However, many studies on the genetic relationship between cannabis use and psychosis have lacked data on both phenotypes within the same individuals, creating challenges due to unmeasured confounding. We aimed to address this by using multimodal data from the All of Us Research Program, which contains genetic data as well as information on SCZ diagnosis and cannabis use.

METHODS: We tested the association between cannabis use disorder (CUD) and SCZ polygenic scores (PGSs) with SCZ and heavy cannabis …

Peer support has demonstrated efficacy in alleviating symptoms of anxiety and depression, while fostering empathy and mitigating burnout among healthcare professionals. Given the considerable demands of residency training, there is a strong rationale for resident-led peer support interventions. However, structured programs to train residents for such leadership roles remain limited. Our objective was to implement a peer support leader training program for residents, evaluate its perceived effectiveness, and identify common themes discussed in sessions. Between June 2021 and June 2023, we performed a longitudinal, prospective cohort survey study of Emergency Medicine (EM) and EM/Pediatrics (EM/P) residents participating in a novel …

2020-Current year OA Pubs

The intracellular processing route used by type I conventional dendritic cells (cDC1) for cross-presentation of viral- or tumor-associated antigens remains controversial. One model proposes that captured antigens exit from damaged phagolysosomes and enter the cytosol, where they are processed for presentation by MHC class I molecules (MHC-I). This model relies on proteasomal degradation and TAP-dependent peptide transport into the endoplasmic reticulum (ER) for loading by the peptide loading complex (PLC). An alternative model proposes a vesicular route in which captured antigens are retained and processed within an endocytic compartment. A compelling argument favoring the cytosolic model is the dramatic loss …

The Inferred Functional Connectome Underlying Circadian Synchronization In The Mouse Suprachiasmatic Nucleus, K L Nikhil, Bharat Singhal, Daniel Granados-Fuentes, Jr-Shin Li, István Z Kiss, Erik D Herzog

2020-Current year OA Pubs

Circadian rhythms in mammals arise from the spatiotemporal synchronization of ~20,000 neuronal clocks in the suprachiasmatic nucleus (SCN). Although anatomical, molecular, and genetic approaches have revealed diverse SCN cell types, how network-level wiring enables their synchronization remains unclear. To overcome the challenges of inferring functional connectivity from fixed tissue, we developed Mutual Information & Transfer Entropy (MITE), an information-theoretic framework to infer directed cell-cell connections with high fidelity from long-term live-cell imaging. Recording and analyzing 3,290 h of clock gene expression from 8,261 SCN neurons across 17 mice, we uncovered a highly conserved, sparse SCN network organized into two asymmetrically …

2020-Current year OA Pubs

Glioblastomas (GBMs) are incurable brain tumors. Zika virus (ZIKV) has specificity in killing GBM stem cells, which drive treatment resistance. In mouse models of GBM, ZIKV also generates an anti-tumor inflammatory response and prolongs survival. To support clinical development and address safety concerns for intra-tumoral treatment, we assessed the effects of injection of an immune-sensitized ZIKV (Δ10 3'-UTR ZIKV), which cannot be transmitted by mosquitos, into non-tumor-bearing rhesus macaque brains. After injection, the primates showed no clinical signs of illness. Histologically, as expected, ZIKV infection elicited mild inflammation, which resolved within 2 weeks. No infectious virus was detected in the …

INTRODUCTION: Myeloid malignancies, including acute myeloid leukemia (AML) and myeloproliferative neoplasms (MPN), exhibit overlapping pathophysiology. Chronic MPNs can transform into secondary AML (sAML), which is associated with poor prognosis and limited treatment options. However, the process and prognostic significance of leukemic transformation remain incompletely understood.

METHOD: Through a two-sample bidirectional Mendelian randomization (MR) analysis, we showed that genetic liability to MPN significantly predicts the risk of developing AML, establishing MPN as the precursor to leukemia. To identify mediators of this risk, we integrated population-level plasma proteomics data, identifying 55 proteins associated with MPN. Upon integrative analysis with the BEAT-AML cohort, …

Baseline Ecg And Cardiovascular Outcomes In People With Hiv: Insights From Reprieve, Aya Awwad, Shashwatee Bagchi, Et Al.

2020-Current year OA Pubs

BACKGROUND: With antiretroviral therapy, people with HIV (PWH) have an increased burden of cardiovascular disease. The REPRIEVE (Randomized Trial to Prevent Vascular Events in HIV) trial demonstrated that pitavastatin reduces major adverse cardiovascular events (MACEs) among PWH at low to moderate traditional atherosclerotic risk. Electrocardiographic abnormalities are common in PWH, but little is known about their association with MACEs. We sought to examine whether baseline electrocardiographic abnormalities are associated with increased MACE risk among a global primary cardiovascular disease prevention cohort of PWH in REPRIEVE.

METHODS: In this observational analysis, entry electrocardiographic abnormalities were adjudicated and classified as major or …

Nuclear Factor IA, a member of the long-studied Nuclear Factor I family of DNA-binding proteins, plays pivotal roles in development and metabolism. Dysregulation or loss of Nuclear Factor IA is associated with severe neurological defects in humans and disruptions in fatty acid metabolism linked to conditions such as osteoarthritis. Despite extensive study, the DNA recognition mechanism of Nuclear Factor I family proteins remains unresolved. Previous studies have proposed that these proteins dimerize via their DNA-binding domains to bind TGGCA-containing dyad sequences. In this study, we demonstrate that both full-length Nuclear Factor IA and its isolated DNA-binding domain are monomeric in …

Methylation-Based Signature To Distinguish Indolent And Aggressive Prostate Cancer, Muheng Liao, Jace Webster, Amy Ly, Emily Rozycki, Christopher A Maher

2020-Current year OA Pubs

Prostate cancer management faces significant challenges in distinguishing indolent from aggressive disease, particularly since most patients are intermediate-risk and therefore hinders the ability to recommend standardized treatment recommendations. Moreover, current prognostic tools including Gleason scoring and tumor staging demonstrate limited accuracy for predicting disease progression and tumor recurrence. DNA methylation serves as a stable epigenetic modification that directly regulates gene expression, making it an ideal biomarker for cancer prognosis. Therefore, this study leveraged whole-genome enzymatic methylation sequencing on 120 patients to develop a novel prognostic signature for aggressive prostate cancer progression. We analyzed 20,849 differentially methylated regions (DMRs) and employed …

Spatial omics (SO) produces high-definition mapping of subcellular molecules within tissue samples. Mapping transcripts to anatomical regions requires segmentation, but this remains challenging in tissue cross-sections with tubular structures like axons in peripheral nerve or spinal cord. Neural networks could address misidentification but are hindered by the need for extensive human annotations. We present SiDoLa-NS (Simulate, Don't Label-Nervous System), an image-driven (top-down) approach to SO analysis in the nervous system. We utilize biophysical properties of tissue architectures to design synthetic images of tissue samples, eliminating reliance on manual annotation and enabling scalable training data generation. With synthetic samples, we trained …

Superior Transplant Recipient Outcome Prediction And Pathology Assessment Using Rapid Deep Learning Applied To Procurement Kidney Biopsies, Joseph P Gaut, Jon N Marsh, Ling Chen, Fan Zhang, Xiaobing Yu, Parker Wilson, Ta-Chiang Liu, S Joshua Swamidass

2020-Current year OA Pubs

Evaluating the suitability of deceased organ donor kidneys relies on clinical, laboratory, and biopsy data. Pathologist quantitation of glomerulosclerosis is a critical histologic parameter used in the decision to transplant. This is an arduous task with modest reproducibility and inconsistent correlation with graft outcomes. Prior work shows that deep learning methods automate glomerulosclerosis quantitation with performance superior to on-call pathologists. Extending beyond this prior work, in this study we find that deep learning glomerulosclerosis quantitation better correlates with graft outcomes. A customized and updated deep learning model was used to analyze 691 procurement biopsies of transplanted kidneys with an average …

Klebsiella pneumoniae is a leading cause of nosocomial infections, bacteremia, and worldwide mortality. Further, a drastic rise in antibiotic-resistant isolates poses an urgent threat to humanity. Unfortunately, despite its clinical importance, a licensed K. pneumoniae vaccine is not yet available. Here, we report on the production and characterization of the broadest K. pneumoniae capsule bioconjugate vaccine to date. We tested this vaccine for its immunogenicity, functionality, efficacy, and antibody durability against a variety of K. pneumoniae isolates in a murine bacteremia model. We also established an immunocompromised murine model of bacteremia to better recapitulate human infection and tested our vaccine's …

Early Genetic Evolution Of Driver Mutations In Uveal Melanoma, James J Dollar, Kisha D Piggott, Et Al.

2020-Current year OA Pubs

Uveal melanoma (UM) is an aggressive eye cancer that frequently results in metastatic death despite successful primary tumor treatment. Subclinical micrometastasis is thought to occur early, when tumors are small and difficult to distinguish from benign nevi. However, the early genetic evolution of UM is poorly understood, and biomarkers for malignant transformation are lacking. Here, we perform integrated genetic profiling of 1140 primary UMs, including 131 small tumors. A clinically available 15-gene expression profile (15-GEP) prospectively validated by our group is more accurate than driver mutations for predicting patient survival. Small tumors are significantly more likely to be in earlier …

Conservation Of Cis-Regulatory Codes Over Half A Billion Years Of Evolution, Yohey Ogawa, Yu Liu, Connie A Myers, Ala Morshedian, Gordon L Fain, Alapakkam P Sampath, Joseph C Corbo

2020-Current year OA Pubs

Identifying homologous cell types across species is essential for understanding cell type evolution. The retina is ideal for comparative analysis because its six major cell classes have persisted since the origin of vertebrates more than half a billion years ago. Here, we show that the retina's conserved cellular architecture is mirrored by deep conservation of the cis-regulatory codes that govern gene expression. Through single-cell chromatin accessibility analysis of lamprey, fish, bird, and mammalian retinas, we demonstrate cross-species conservation of cis-regulatory codes in all retinal cell classes despite extensive turnover of cis-regulatory regions. Conservation manifests as clustering of high-affinity transcription factor …

In The Mouth Or In The Gut? Innovation Through Implementing Oral And Gastrointestinal Health Science In Chronic Pain Management, Jo Nijs, Burel R Goodin, Et Al.
