Molecular Typing Of Rickettsia Akari, Marina E. Eremeeva

Biostatistics, Epidemiology & Environmental Health Sciences: Faculty Publications

Rickettsia akari is an obligate intracellular bacterium that causes smallpox rickettsia. Rickettsia akari is an atypical member of the rickettsia spotted fever (SFG) group because it circulates in gamasid mites; however, only limited data are available regarding the degree of genetic diversity of R. akari isolates. We examined 13 isolates of R. akari isolated from humans, rodents, and ticks in the United States, the countries of the former USSR, and the former Yugoslavia for the period from 1946 to 2003 for diversity in the composition of tandem repeats (TR) and intergenic regions (IGR). Using the Tandem Repeat Finder software (http://tandem.bu.edu) …

Rickettsialpox – A Rare But Not Extinct Disease: A Review Of The Literature And New Directions, Marina Eremeeva, Kamalich Muniz-Rodriguez

Biostatistics, Epidemiology & Environmental Health Sciences: Faculty Publications

Smallpox rickettsia is an urban zoonosis caused by Rickettsia akari. To date, R. akari is the only characterized representative of the group of spotted fevers transmitted by the gamasid mite Liponyssoides sanguineus, which is common among peridomic rodents. This disease was first described in New York in 1946, and a few years later a similar outbreak occurred in the Ukrainian SSR. Numerous serological studies and diagnostics of sporadic cases of smallpox rickettsiosis suggest its widespread occurrence on the planet; however, the current geography and incidence of smallpox rickettsiosis is unknown. Smallpox rickettsiosis is characterized by the classic clinical triad of …

Urban Food Sovereignty: Urgent Need For Agroecology And Systems Thinking In A Post-Covid-19 Future, Ali Loker, Charles A. Francis

Department of Agronomy and Horticulture: Faculty Publications

The current COVID-19 pandemic has brought attention to challenges associated with our dominant industrial food system in the U.S. The general public now has more appreciation for farm workers and meatpacking employees, as well as those in grocery stores and in food transportation who are suddenly recognized as essential frontline workers. It apparently takes a crisis for us to focus clearly on the fragility of this system and the lives of people on whom we depend. In this commentary we discuss the definition of food sovereignty, how it manifests in urban areas, and how the COVID-19 pandemic can trigger viable …

Rethinking Global Governance To Address Zoonotic Disease Risks: Connecting The Dots, Kelley Lee

Animal Sentience

Large-scale changes in human behaviour are urgently needed to prevent future pandemics involving zoonotic diseases such as COVID-19. However, this will not happen to the required degree, and with sufficient speed, without a major shift in how humanity collectively governs itself. Alongside a shift in focus from individual behaviours to the structural conditions underpinning the world economy that shape human behaviours, effective global governance presses us to connect more dots than ever before. The One Health approach is an important starting point but we need to go much further.

Human Skills Assessment As A Support To Human Factor Management, Lorenzo Comberti, Micaela Demichela, Maria Chiara Leva

Conference papers

Automatization, robotics and Industry 4.0 are deeply modifying the working condition with an expected reduction of the number of workers employed in traditional job and an increasing request of new professions. Despite these technologies could limit the involvement of workers, in some sectors humans are still widely employed, as in assembly line of manufacturing companies. As a consequence of this, the Human Factor (HF) will still have relevant influence in term efficiency, quality and safety performances.

This paper approached the HF analysis into the manufacturing field in an assembly line. This study was focused on the analysis of those human-skills …

The 2014 West Virginia Elk River Chemical Leak: A Case Study Of Respiratory Health Disparities And Drinking Water Contamination, Maya Nye

Graduate Theses, Dissertations, and Problem Reports (ETD)

This case study supplements existing data with original analysis to address environmental pollution burden and health effects not previously examined from the 2014 Freedom Industries Elk River chemical leak in West Virginia. Comparisons were made between the peer-reviewed literature, governmental disaster management practices implemented during the leak, and alternative human health assessment models to determine whether the evidence relied upon for decision-making was adequate for protecting public health, minimizing health disparities and increasing health equity. An emphasis was placed on understanding how the state and federal government approached human health hazard assessment and health outcome reporting, particularly of socially vulnerable …

Correlation Of Circulating Angptl5 Levels With Obesity, High Sensitivity C-Reactive Protein And Oxidized Low Density Lipoprotein In Adolescents, Maha M. Hammad, Mohamed Abu-Farha, Abdullah Al-Taiar, Nada Alam-Eldin, Reem Al-Sabah, Lemia Shaban, Fahd Al-Mulla, Jehad Abubaker, Abdur Rahman

Community & Environmental Health Faculty Publications

Angiopoietin-like proteins (ANGPTL) is a family of eight members known to play an important role in metabolic diseases. Of these, ANGPTL5 is suggested to regulate triglyceride metabolism and is increased in obesity and diabetes. However, its role in metabolic diseases in adolescents is not well-studied. In this study, we tested the hypothesis of a positive association between plasma ANGPTL5, and obesity, high sensitivity C-reactive protein (HsCRP) and oxidized low-density lipoprotein (Ox-LDL) in adolescents. Adolescents (N = 431; age 11–14 years) were randomly selected from middle schools in Kuwait. Obesity was classified by the BMI-for-age based on the WHO growth charts. …

Contaminants Of Emerging Concern: Reconsidering Our Paradigm Of Water Pollution, Jonathan Gunasti

Pomona Senior Theses

In this senior thesis, I explore contaminants of emerging concern (CECs) and endocrine disrupting compounds (EDCs) and discuss the ways in which these novel contaminants defy traditional notions of pollution. I discuss the history and “emergence” of CECs and EDCs in scientific and public spheres and outline ongoing challenges to recognizing, prioritizing, and understanding the action of these contaminants. I position EDCs within the framework of environmental injustice and health disparities and suggest that these compounds could reinforce multigenerational health inequities. Finally, I perform a pilot analysis of the EDC bisphenol A (BPA) in Mt. Baldy Creek, the Los Angeles …

Accounting For The Uncertainty Due To Chemicals Below The Detection Limit In Mixture Analysis, Paul M. Hargarten

Theses and Dissertations

Humans are exposed to multiple chemicals every day. Epidemiological studies have shown that chemical mixtures are associated with cancers, allergies, neurodevelopmental disorders, and other adverse health effects. To assess these associations, investigators are increasingly using chemical mixture approaches like weighted quantile sum (WQS) regression. In these studies, the research objectives are to determine whether a mixture of correlated chemicals is associated with an adverse health outcome and to identify the important chemicals. However, as experimental equipment measures each exposure to a chemical-specific detection limit, the exposures are unknown between zero and the detection limit. Indeed, the number of exposures below …

Pinworm Research In The Southwest Usa: Five Decades Of Methodological And Theoretical Development And The Epidemiological Approach, Morgana Camacho, Karl Reinhard

Karl Reinhard Publications

Pinworms infected Ancestral Pueblo populations since early periods of occupation on the Colorado Plateau. The high prevalence of pinworm found in these populations was correlated with the habitation style developments through time. However, in previous studies, Turkey Pen Cave, an early occupation site, and Salmon Ruins, a late occupation site, exhibited prevalences that were anomalously low, suggesting that these sites were outliers. Alternatively, it is possible that the previous quantification method was not successful in detecting the real prevalence and eggs per gram, which led to inexact interpretations. The aims of this study were to verify if previous pinworm prevalences …

Diet Analysis Reveals Pre-Historic Meals Among The Loma San Gabriel At La Cueva De Los Muertos Chiquitos, Rio Zape, Mexico (600–800 Ce), Elisa Pucu, Julia Russ, Karl Reinhard

Karl Reinhard Publications

Coprolites have been a source of study for archeologists due to several reasons: they not only provide information on the life and nutritional habits of ancient individuals but also on their health. In this paper, we processed 10 coprolites collected at La Cueva de Los Muertos Chiquitos (600–800 CE), Rio Zape, Mexico, with acetolysis solution for pollen analysis. The number of pollen grains/gram of each coprolite sample was quantified along with the macroscopic remains of these samples. The main food item ingested by the population was maize, followed by Agave. Squash blossoms were also part of their food source …

Shotgun metagenomics applied to archaeological feces (paleofeces) can bring new insights into the composition and functions of human and animal gut microbiota from the past. However, paleofeces often undergo physical distortions in archaeological sediments, making their source species difficult to identify on the basis of fecal morphology or microscopic features alone. Here we present a reproducible and scalable pipeline using both host and microbial DNA to infer the host source of fecal material. We apply this pipeline to newly sequenced archaeological specimens and show that we are able to distinguish morphologically similar human and canine paleofeces, as well as non-fecal …

Distribution Of Human Exposure To Ozone During Commuting Hours In Connecticut Using The Cellular Device Network, Owais Gilani, Simon Urbanek, Michael J. Kane

Faculty Journal Articles

Epidemiologic studies have established associations between various air pollutants and adverse health outcomes for adults and children. Due to high costs of monitoring air pollutant concentrations for subjects enrolled in a study, statisticians predict exposure concentrations from spatial models that are developed using concentrations monitored at a few sites. In the absence of detailed information on when and where subjects move during the study window, researchers typically assume that the subjects spend their entire day at home, school, or work. This assumption can potentially lead to large exposure assignment bias. In this study, we aim to determine the distribution of …

Reconciling Environmental Justice With Climate Change Mitigation: A Case Study Of Nc Swine Cafos, D. Lee Miller, Ryke Longest

Faculty Scholarship

For thirty years, the swine industry has externalized severe environmental and health harms onto poor communities of color in Eastern North Carolina. This “Big Pig” problem is caused by the confinement, consolidation, and concentration of industrial hog operations within the low, flat, and economically marginalized Coastal Plain. Big Pig’s rise was not inevitable. As recently as 1982, more than 11,000 small swine farms freckled nearly all of North Carolina’s 100 counties. Then came the “boom” of consolidation and industrialization that transformed hog production into a highly consolidated and vertically integrated industry.
