Gut microbes are known to be able to alter kynurenine metabolites in the host, directly influencing innate immunity in C. elegans. While the mitochondrial unfolded protein response (UPR^(mt)) was first characterized in C. elegans in 2007, its relevance in host-microbiome interactions has only become... Wed, 27 Nov 2024 06:00:00 -0500 Recent publications from TDC/Clinical Epidemiology authors: A Reproducible Protocol for the Isolation of Malaria-Derived Extracellular Vesicles by Differential Centrifugation https://pubmed.ncbi.nlm.nih.gov/39584985/?utm_source=Other&utm_medium=rss&utm_campaign=pubmed-2&utm_content=1zSVwQViw4htk0ptJE-rdb4g98Hn0Vy51ceCnixBnFkL6ILsbf&fc=20201106102241&ff=20241126041309&v=2.18.0.post9+e462414 Over the last few decades, malaria-derived extracellular vesicles (EVs) have gained increasing interest due to their role in disease pathophysiology and parasite biology. Unlike other EV research fields, the isolation of malaria EVs is not standardized, hampering inter-study comparisons. Most malaria EV studies isolate vesicles by the "gold-standard" technique of differential (ultra)centrifugation (DC). Here, we describe in detail an optimized and reproducible protocol for the isolation of... Mon, 25 Nov 2024 06:00:00 -0500 Recent publications from TDC/Clinical Epidemiology authors: Continuous characterisation of exacerbation pathophysiology using wearable technologies in free-living outpatients with COPD: a prospective observational cohort study https://pubmed.ncbi.nlm.nih.gov/39579617/?utm_source=Other&utm_medium=rss&utm_campaign=pubmed-2&utm_content=1zSVwQViw4htk0ptJE-rdb4g98Hn0Vy51ceCnixBnFkL6ILsbf&fc=20201106102241&ff=20241125020112&v=2.18.0.post9+e462414 BACKGROUND: The most recent exacerbation of COPD (ECOPD) classification criteria relies in part on changes in respiratory rate (RR), heart rate (HR) and oxygen saturation (SpO(2)). Despite this paradigm shift, a thorough understanding of exacerbation patterns is still lacking, as is the identification of physiological exacerbation biomarkers. Sat, 23 Nov 2024 06:00:00 -0500 Recent publications from TDC/Clinical Epidemiology authors: Oropouche Virus: A Rising Threat in the Western Hemisphere https://pubmed.ncbi.nlm.nih.gov/39556840/?utm_source=Other&utm_medium=rss&utm_campaign=pubmed-2&utm_content=1zSVwQViw4htk0ptJE-rdb4g98Hn0Vy51ceCnixBnFkL6ILsbf&fc=20201106102241&ff=20241119004349&v=2.18.0.post9+e462414 No abstract Mon, 18 Nov 2024 06:00:00 -0500 Recent publications from TDC/Clinical Epidemiology authors: Next-generation rapid phenotypic antimicrobial susceptibility testing https://pubmed.ncbi.nlm.nih.gov/39521792/?utm_source=Other&utm_medium=rss&utm_campaign=pubmed-2&utm_content=1zSVwQViw4htk0ptJE-rdb4g98Hn0Vy51ceCnixBnFkL6ILsbf&fc=20201106102241&ff=20241114002954&v=2.18.0.post9+e462414 Slow progress towards implementation of conventional clinical bacteriology in low resource settings and strong interest in greater speed for antimicrobial susceptibility testing (AST) more generally has focused attention on next-generation rapid AST technologies. In this Review, we systematically synthesize publications and submissions to regulatory agencies describing technologies that provide phenotypic AST faster than conventional methods. We characterize over ninety technologies in terms of...

Measuring host response markers of inflammation and endothelial activation at clinical presentation may help to inform appropriate triage and care practices in patients with SARS-CoV-2 infection. Sat, 26 Oct 2024 06:00:00 -0400 Recent publications from TDC/Clinical Epidemiology authors: MicrobiomeNet: exploring microbial associations and metabolic profiles for mechanistic insights https://pubmed.ncbi.nlm.nih.gov/39441071/?utm_source=Other&utm_medium=rss&utm_campaign=pubmed-2&utm_content=1zSVwQViw4htk0ptJE-rdb4g98Hn0Vy51ceCnixBnFkL6ILsbf&fc=20201106102241&ff=20241024005619&v=2.18.0.post9+e462414 The growing volumes of microbiome studies over the past decade have revealed a wide repertoire of microbial associations under diverse conditions. Microbes produce small molecules to interact with each other as well as to modulate their environments. Their metabolic profiles hold the key to understanding these association patterns for translational applications. Based on this concept, we developed MicrobiomeNet, a comprehensive database that integrates microbial associations with their metabolic...

Penile, anorectal, and oral exposures predicted lesion presence at correlating anatomic sites. Exposure site also predicted the first lesion site of the penis and anus.
