Beyond Low-Earth Orbit: Characterizing Immune And Microrna Differentials Following Simulated Deep Spaceflight Conditions In Mice, Amber M. Paul, Margareth Cheng-Campbell, Elizabeth A. Blaber, Sulekha Anand, Sharmila Bhattacharya

Publications

Spaceflight missions can cause immune system dysfunction in astronauts with little understanding of immune outcomes in deep space. This study assessed immune responses in mice following ground-based, simulated deep spaceflight conditions, compared with data from astronauts on International Space Station missions. For ground studies, we simulated microgravity using the hindlimb unloaded mouse model alone or in combination with acute simulated galactic cosmic rays or solar particle events irradiation. Immune profiling results revealed unique immune diversity following each experimental condition, suggesting each stressor results in distinct circulating immune responses, with clear consequences for deep spaceflight. Circulating plasma microRNA sequence analysis revealed …

Let-Dependent Low Dose And Synergistic Inhibition Of Human Angiogenesis By Charged Particles: Validation Of Mirnas That Drive Inhibition, Amber M. Paul, Yen-Ruh Wuu, Burong Hu, Hazeem Okunola, Elizabeth A. Blaber, Margareth Cheng-Campbell, Afshin Beheshti, Peter Grabham

Publications

Space radiation inhibits angiogenesis by two mechanisms depending on the linear energy transfer (LET). Using human 3D micro-vessel models, blockage of the early motile stage of angiogenesis was determined to occur after exposure to low LET ions (/AMU), whereas inhibition of the later stages occurs after exposure to high LET ions (>8 KeV/AMU). Strikingly, the combined effect is synergistic, detectible as low as 0.06 Gy making mixed ion space radiation more potent. Candidates for bystander transmission are microRNAs (miRNAs), and analysis on miRNA-seq data from irradiated mice shows that angiogenesis would in theory be downregulated. Further analysis of three …

Aerobic Exercise With Superimposed Virtual Reality Improves Cognitive Flexibility And Selective Attention In Young Males, Borja Sañudo, Ellie Abdo, Mario Bernardo-Filho, Redha Taiar

Publications

The literature to date is limited regarding the implantation of VR in healthy young individuals with a focus on cognitive function. Thirty healthy males aged between 22.8 and 24.3 years volunteered to participate in the study randomly and were assigned to one of two groups with alike exercises: an experimental group (GE, n = 15) that performed an exercise protocol with a VR game and a controlled group that performed the exercise protocol without the VR (CON, n = 15). A 128-card computerized version of the Wisconsin Card Sorting Task (WCST) and the Stroop test were completed before and after …

Neutrophil-To-Lymphocyte Ratio: A Biomarker To Monitor The Immune Status Of Astronauts, Amber M. Paul, Siddhita D. Mhatre, Egle Cekanaviciute, Ann-Sofie Schreurs, Candice G.T. Tahimic, Ruth K. Globus, Sulekha Anand, Brian E. Crucian, Sharmila Bhattacharya

Publications

A comprehensive understanding of spaceflight factors involved in immune dysfunction and the evaluation of biomarkers to assess in-flight astronaut health are essential goals for NASA. An elevated neutrophil-to-lymphocyte ratio (NLR) is a potential biomarker candidate, as leukocyte differentials are altered during spaceflight. In the reduced gravity environment of space, rodents and astronauts displayed elevated NLR and granulocyte-to-lymphocyte ratios (GLR), respectively. To simulate microgravity using two well-established ground-based models, we cultured human whole blood-leukocytes in high-aspect rotating wall vessels (HARV-RWV) and used hindlimb unloaded (HU) mice. Both HARV-RWV simulation of leukocytes and HU-exposed mice showed elevated NLR profiles comparable to spaceflight …

A Statistical Learning Regression Model Utilized To Determine Predictive Factors Of Social Distancing During Covid-19 Pandemic, Timothy A. Smith, Albert J. Boquet, Matthew V. Chin

Publications

In an application of the mathematical theory of statistics, predictive regression modelling can be used to determine if there is a trend to predict the response variable of social distancing in terms of multiple predictor input “predictor” variables. In this study the social distancing is measured as the percentage reduction in average mobility by GPS records, and the mathematical results obtained are interpreted to determine what factors drive that response. This study was done on county level data from the state of Florida during the COVID-19 pandemic, and it is found that the most deterministic predictors are county population density …

Surveying The Safety Culture Of Academic Laboratories, Emily Faulconer, Zachary Dixon, John C. Griffith, Hayden Frank

Publications

The university traditionally has been the foundation for young adults’ professional development, yet the proclivity toward safety culture has garnered less focus in higher education than in the workforce. A survey of faculty at a medium-sized, research-active, private institution revealed specific areas of policy noncompliance as well as specific safety attitudes that can be targeted for interventions. Albeit a snapshot view, the survey implies that safety needs better representation in the classroom, teaching laboratories, and research facilities at universities. Safety is not abandoned by any means, and there is a strong presence of safety-oriented individuals, but the data show barriers …

Teachers’ Perceptions And Understanding Of Children’S Fluid Intake, Kristy Howells, Tara Coppinger

Publications

No public health data exists on elementary teachers’ perceptions of both their own fluid intake and of their elementary school aged children’s fluid intake. A total of 271 (20 males, 251 females) teachers in developed areas of Australia, Belgium, England, Ireland, United Arab Emirates, and the United States of America completed an online questionnaire (Feb–Mar 2019) on: (i) their fluid intake, (ii) their perception and understanding of children’s fluid intake and (iii) barriers in the school day that they felt prevented school children consuming fluids. Overall, the data indicated that teachers consume considerably lower amounts than recommended themselves, but have …

The Value Of Iaq: A Review Of The Scientific Evidence Supporting The Benefits Of Investing In Better Indoor Air Quality, Vickie R. Hawkins,, Cheryl L. Marcham, John P. Springston, J. David Miller, Geoffrey Braybrooke, Craig Maunder, Lydia Feng, Ben Kollmeyer

Publications

Other studies have examined how ventilation rates, combined with the presence of pollutant sources, can affect productivity. These studies provide evidence that increased ventilation, including increases above common guidance levels such as ASHRAE’s ventilation standards, improve occupant productivity. Increased occupant control over ventilation has also been shown to improve productivity. Higher indoor carbon dioxide (CO2) levels have been directly associated with impaired work performance and increased health symptoms. Historically, it was believed that these associations exist only because higher indoor CO2 concentrations, resulting from lower outdoor air ventilation rates, are also correlated with higher levels of other indoor-generated pollutants that …

Perceptions And Determinants Of Partnership Trust In The Context Of Community-Based Participatory Research, Arelis Moore De Peralta, Julie Smithwick, Myriam E. Torres

Publications

Trust is difficult to conceptualize and define because of its diverse applications in different disciplines. Historic mistrust between vulnerable communities and researchers based on past adverse experiences can negatively affect the ability to collaborate and conduct effective research with such populations. Community Based-Participatory Research (CBPR) is a collaborative approach to research that can reduce historic mistrust and health disparities among minority populations. Although how trust development occurs in CBPR partnerships has been explored, there is a need to determine how to move from one stage to the next in fostering and maintaining that trust. The present study contributes to this …

Recovering From Covid-19 Building Closures: Guidance Document, David Krause, Cheri Marcham, John Springston, Alex Lebeau, Robert Rottersman, Timothy Froehlig, Bart Ashley

Publications

While the country comes to terms with the inevitable impact that SARS-CoV-2, the virus that causes COVID-19, will have on our lives and communities, public health authorities remain focused on breaking the chain of transmission. Managing the risk has resulted in widespread closures of businesses, schools, universities, resorts, and other facilities deemed “non-essential.” Practically speaking, this means closing buildings and ceasing operations. For building owners and operators, this poses a significant challenge to protect their assets and to ensure they are ready to reoccupy once the pandemic subsides.

Workplace Cleaning For Covid-19: Guidance Document, David Krause,, Cheri Marcham, John Springston, Alex Lebeau, Robert Rottersman, Timothy Froehlig, George (Jerry) Mccaslin

Publications

Critical and essential workplaces operating during this pandemic need to implement procedures to reduce the risk of workers, contractors, vendors, customers, and members of the community becoming infected on their premises. Outside of healthcare and paramedical facilities, the infrastructure and standard practices of infection prevention and control have not been commonplace. Establishing enhanced routine cleaning and disinfection procedures in offices, factories, warehouses, call centers, grocery stores, and other non-healthcare workplaces is a critical step in reducing exposures and infections.

Explainable Ai Using Knowledge Graphs, Manas Gaur, Ankit Desai, Keyur Faldu, Amit Sheth

Publications

During the last decade, traditional data-driven deep learning (DL) has shown remarkable success in essential natural language processing tasks, such as relation extraction. Yet, challenges remain in developing artificial intelligence (AI) methods in real-world cases that require explainability through human interpretable and traceable outcomes. The scarcity of labeled data for downstream supervised tasks and entangled embeddings produced as an outcome of self-supervised pre-training objectives also hinders interpretability and explainability. Additionally, data labeling in multiple unstructured domains, particularly healthcare and education, is computationally expensive as it requires a pool of human expertise. Consider Education Technology, where AI systems fall along a …

Physiological Effects During Aerobatic Flights On Science Astronaut Candidates, Pedro Llanos, Diego M. Garcia

Publications

Spaceflight is considered the last frontier in terms of science, technology, and engineering. But it is also the next frontier in terms of human physiology and performance. After more than 200,000 years humans have evolved under earth’s gravity and atmospheric conditions, spaceflight poses environmental stresses for which human physiology is not adapted. Hypoxia, accelerations, and radiation are among such stressors, our research involves suborbital flights aiming to develop effective countermeasures in order to assure sustainable human space presence. The physiologic baseline of spaceflight participants is subject to great variability driven by age, gender, fitness, and metabolic reserve. The objective of …

Association Of Patient-Centered Medical Home Designation And Quality Indicators Within Hrsa-Funded Community Health Center Delivery Sites, Nathaniel Bell, Rebecca Wilkerson, Kathy Mayfield-Smith, Ana Lopez-De Fede

Publications

Background: Patient-Centered Medical Home (PCMH) adoption is an important strategy to help improve primary care quality within Health Resources and Service Administration (HRSA) community health centers (CHC), but evidence of its effect thus far remains mixed. A limitation of previous evaluations has been the inability to account for the proportion of CHC delivery sites that are designated medical homes. Methods: Retrospective cross-sectional study using HRSA Uniform Data System (UDS) and certification files from the National Committee for Quality Assurance (NCQA) and the Joint Commission (JC). Datasets were linked through geocoding and an approximate string-matching algorithm. Predicted probability scores were regressed …

Pennsylvania’S Covid-19 Response Vs. Homeland Security Frameworks And Research: Masking The Whole Community, Alexander Siedschlag

Publications

This essay offers an intermediate discussion of select policy, strategic, operational, and tactical issues that demonstrate where and how the Commonwealth of Pennsylvania’s novel coronavirus response on the one hand, and homeland security frameworks and research on the other, converge or—more often so—diverge, and how to narrow this gap. Although typically framed as a pandemic owned by the public health sector, the COVID-19 response falls directly within the homeland security mission space, whose core missions include “Ensuring Resilience to Disasters.” In some respects, Pennsylvania’s response exemplifies best practices suggested by research. In other dimensions, it is neither in line with …
