Exploring The Evolution Of Trypanosoma Cruzi And The Emergence Of Chagas Disease In The Context Of Environmental Change: Applying The Stockholm Paradigm To Archaeoparasitology, Part I, Aida Romera Barbera, Daniel R. Brooks, T. Michael Fink, Karl J. Reinhard

Karl Reinhard Publications

The Stockholm Paradigm is an evolutionary synthesis that explains the emergence of novel pathogens in the context of environmental disturbances. Considering the urgent climate change situation, anticipation stands as key to prevent and mitigate the effects that climate change can have in the emergence of pathogens. However, the success of preventive measures is hindered by a limited knowledge of the interplaying dynamics between biology, environment, and culture leading to emerging infectious diseases. For many decades, bioarchaeologists have been gathering data on past human-environment interactions, therefore contributing to the conversation. Archaeoparasitology, at the intersection between pathology, bioarchaeology, and biology, is uniquely …

Documenting The Presence Of Chagas Disease In Prehistoric North America: Applying The Stockholm Paradigm To Archaeoparasitology, Part Ii, Karl J. Reinhard, Daniel R. Brooks, Aida Romera Barbera, T. Michael Fink

Karl Reinhard Publications

The DAMA protocol (Document, Assess, Monitor, Act) is the applied aspect of the Stockholm Paradigm. Evidence from archaeology and history of medicine has a demonstrated value in documenting infection risk for specific study areas. Bioarchaeological remains and historical documents show vivid examples of pathology related to the Chagas disease life cycle. The science of archaeology defines the lifestyles that created risk of triatomine kissing bug infestations and trypanosome protozoa infections. Paleogenetics, in the form of molecular analyses of Trypanosoma cruzi, elucidate the temporal origins of genetic variants and adaptation to human environments. We illustrate how these fields reveal the risk …

Association Between Residential Exposure To Air Pollution And Incident Coronary Heart Disease Is Not Mediated By Leukocyte Telomere Length: A Uk Biobank Study, Chia-Ling Kuo, Rui Liu, Lucas Da Cunha Godoy, Luke C. Pilling, Richard H. Fortinsky, Doug Brugge

Health Science Faculty Publications

Higher air pollution exposure and shorter leukocyte telomere length (LTL) are both associated with increased risk of coronary heart disease (CHD), and share plausible mechanisms, including inflammation. LTL may serve as a biomarker of air pollution exposure and may be intervened with to reduce the risk of CHD. To the best of our knowledge, we are the first to test the mediation effect of LTL in the relationship between air pollution exposure and incident CHD. Using the UK Biobank (UKB) data (n = 317,601), we conducted a prospective study linking residential air pollution exposure (PM2.5, PM10, NO2, NOx) and …

A Robust Bayesian Model Averaging Method For Basket Trials With Different Endpoints, Xueting Wang

Public Health Theses

Oncology drug research in the last few decades has been driven by the development of targeted agents. In the era of targeted therapies, basket trials are often used to test the antitumor activity of a novel treatment in multiple indications sharing the same genomic alteration. As patient population are further fragmented into biomarker-defined subgroups in basket trials, novel statistical methods are needed to facilitate cross-indication learning to improve the statistical power in basket trial design. Here we propose a robust Bayesian model averaging (rBMA) technique for the design and analysis of phase II basket trials. We consider the posterior distribution …

Psychological Resilience In U.S. Military Veterans: Results From The 2019-2020 National Health And Resilience In Veterans Study, Michael Georgescu

Public Health Theses

Psychological resilience is the most common response following exposure to traumatic life events. To date, most research has focused on factors associated with adverse post-trauma mental health outcomes rather than understanding those associated with psychological resilience. In particular, little is known about factors associated with resilience in veterans, despite their high rates of trauma exposure, such as combat and military sexual trauma. To address this gap, we used a discrepancy-based psychiatric resilience (DBPR) analytic approach to operationalize resilience and to identify modifiable health and psychosocial factors associated with resilience in a nationally representative sample of U.S. veterans (N = 4,069). …

Elucidating Metformin As A Scavenger Of 4-Hne, An Endogenously Produced Aldehyde Associated With Alzheimer’S Disease Progression, In Hek293t Cells, Miren Lopez Lascurain

Public Health Theses

Metformin, a first-line therapy for Type 2 Diabetes Mellitus (T2DM), has been shown to have numerous health benefits in neurodegenerative disease progressions, including Alzheimer’s disease (AD). Vasiliou et al. have recently proposed that metformin is able to scavenge endogenously produced aldehydes such as 4-hydroxy-2-nonenal (4-HNE), which are thought to contribute to the progression and development of AD. Preliminary in vitro and in silico studies demonstrate that metformin scavenges 4-HNE leading to adduct formation. Therefore, this study sought to determine if metformin adducts 4-HNE in a living system. We hypothesize that metformin can scavenge 4-HNE in HEK 293T cells and will …

From Theory To Practice: Zoonotic Spillover, One Health And The Role Of Local Indigenous Communities, Pranav Prabhu Savanur

Public Health Theses

This paper discusses the impact of zoonotic spillovers on public health and the need for a One Health approach to preventing future pandemics. Zoonotic spillovers occur when pathogens are transmitted from animals to humans, facilitated by anthropogenic land changes, migration or trade, increased human-animal contact, and poor biosafety. However, anthropogenic land use change is the primary driver for zoonotic spillovers. Most emerging infectious diseases in humans are of zoonotic origin, and the impact of these spillovers on public health is significant. The paper emphasizes the need to prevent spillover events for primary pandemic prevention, which requires a coordinated and collaborative …

Ultrahigh-Performance Liquid Chromatography–Tandem Mass Spectrometry Quantitation Of O-Cresol In Hydrolyzed Human Urine To Assess Toluene Exposure, Eric Langlois, Sébastien Gagné

Études primaires

Rationale

Toluene is a volatile organic compound used in domestic and industrial applications. The main routes of workplace exposure to toluene are inhalation and dermal contact. As toluene exposure can cause severe nervous system damage, its quantification is crucial to prevent occupational illness. Toluene is metabolized mainly as hippuric acid, S-benzylmercapturic acid and epoxides. These are rapidly converted to o-/p-cresol, which is then excreted in the urine as conjugated glucuronides and sulfates. o-Cresol and its conjugates can be chemically hydrolyzed to form free o-cresol, which can then serve as a urinary biomarker of toluene exposure. Current …
