The Compounding Effect Of Rurality On Health Disparities Among Black Patients With Covid-19, Jessica E. Johnson, Ruchi Bhandari, Allison Lastinger, Rebecca Reece

Journal of Appalachian Health

Background: West Virginia had garnered national attention for its vaccination rollout against coronavirus 2019 (COVID-19). Outcomes of this mostly rural population, however, have been underreported. As the pandemic continues, identifying high risk populations remains important to further epidemiologic information and target vaccines.

Purpose: The objective of this study is to examine the effects of COVID-19 and the influence of race and rurality on hospitalization and outcomes in Appalachians.

Methods: In this retrospective study, data from patients who tested positive and were admitted for COVID-19 and seen within the state’s largest health system (West Virginia University Health System) between March …

Hearing Health Healthcare Disparities In Appalachia, Matthew L. Bush

Journal of Appalachian Health

Hearing loss is a global public health issue with disproportionate negative impacts on those who live in rural regions, such as Appalachia. This commentary provides an overview of hearing health and healthcare disparities in rural regions along with discussion of the significance of recent research findings which highlight the incidence of hearing loss and the shortage of hearing specialists in Appalachia.

The Importance Of Time, Place, And Person: Applying Elementary Epidemiology To Covid-19 Outcomes In Rural Appalachia, Linda Alexander, F. Douglas Scutchfield Md

Journal of Appalachian Health

Since the 1800s this traditional triad of descriptive epidemiology has allowed for effective interventions to deal with epidemics. A focus on time, place, and person also provides a critical framework for interventions in controlling the epidemic by focusing on those populations with the highest risk for disease.

Cricopharyngeal Myotomy In National Surgical Quality Improvement Program (Nsqip): Complications For Otolaryngologists Versus Non-Otolaryngologists, Ellen M. Piccillo, David Adkins, Mohamed Elrakhawy, Michele M. Carr

Otolaryngology--Head & Neck Surgery Resident Research

OBJECTIVE: Comparing outcomes after cricopharyngeal myotomy (CM) performed by otolaryngologists (OTO) and non-otolaryngologists (NO).

METHODS: A retrospective analysis of the 2014-19 ACS-NSQIP database (American College of Surgeons National Surgical Quality Improvement Program) of patients who underwent open CM (CPT code 43030) as their primary procedure. Analyzed variables include medical comorbidities, operative time, the total length of stay, readmission, reoperation, concurrent procedures, postoperative complications, and postoperative diagnoses. 183 patients were included, 97 (53%) females and 86 (47%) males. 120 had surgery by OTO and 63 by NO.

RESULTS: There were no differences in preoperative morbidity. OTO had more outpatient surgeries compared …

Evaluating Large Spontaneous Deletions In A Bovine Cell Line Selected For Bovine Viral Diarrhea Virus Resistance, Aspen M. Workman, Michael P. Heaton, Dennis A. Webster, Gregory P. Harhay, Theodore S. Kalbfleisch, Timothy P. L. Smith, Shollie M. Falkenberg, Daniel F. Carlson, Tad S. Sonstegard

Maxwell H. Gluck Equine Research Center Faculty Publications

Bovine viral diarrhea virus’s (BVDV) entry into bovine cells involves attachment of virions to cellular receptors, internalization, and pH-dependent fusion with endosomal membranes. The primary host receptor for BVDV is CD46; however, the complete set of host factors required for virus entry is unknown. The Madin-Darby bovine kidney (MDBK) cell line is susceptible to BVDV infection, while a derivative cell line (CRIB) is resistant at the level of virus entry. We performed complete genome sequencing of each to identify genomic variation underlying the resistant phenotype with the aim of identifying host factors essential for BVDV entry. Three large compound deletions …

Behavioral Science Faculty Publications

BACKGROUND: The Human papillomavirus vaccine (HPV) is an essential tool for the prevention of HPV-related cancers. In Puerto Rico, the Secretary of Health established a school entry requirement of at least one dose of HPV vaccination in girls and boys aged 11 and 12 years, taking effect in August 2018. Our study aimed to examine parents' and guardians' views of unvaccinated children about the process of implementation of the new HPV vaccination school entry policy in Puerto Rico and identify potential barriers and facilitators related to the implementation of this requirement.

METHODS: During April through November 2019, we conducted three …

Engaged Research Can Advance Knowledge And Promote Positive Change Among The Rural Poor, D. L. Coppock

IGC Proceedings (1977-2023)

There is increasing interest in investigative processes known as “Engaged Research.” Such approaches include aspects of Farming Systems Research & Extension, Participatory Rural Appraisal, Participatory Action Research, and Innovation Systems. Engaged Research—a term recently popular in the USA—is founded on long-term relationships among stakeholders and emphasizes problem-solving based on co-production of knowledge. We are now at a time when science-based knowledge should be implemented to improve the lives of the rural poor under the triple threat of poverty, natural resource degradation, and climate change. Traditional ways of conducting applied, academic study can be reconfigured to this end, improving research effectiveness …

The Role Of Women In Rural Livestock: Which Women? Which Livestock?, Gabriela Litre, Daniela Nogueira, Alessandra Matte, Virginia Courdin

IGC Proceedings (1977-2023)

We explore the conceptual and empirical limitations of the question about “the role of women in rural livestock production” as well as the widespread assumption that women in livestock are subsistence or smallholder farmers. While this is correct in many situations, “essentialist” development discourses often disregard new demographic trends and the heterogeneity of live-stock production systems. Our research, which focuses on the livelihoods of women involved with livestock production in the Pampas’ grasslands of Brazil, proposes: 1) to critically analyse some of the most widely spread assumptions about women involved in beef livestock production, including the belief that women are …

Shift In Management Strategy Of Yak Herding In The South Of Mustang District, Nepal, Himalaya, H. Anzai, M. K. Shah, Hajime Kumagai

IGC Proceedings (1977-2023)

In the Himalayan regions of Nepal, people herd yaks (Bos grunniens) under transhumant pastoralism, seasonal migrations of herds between summer highlands and winter lowlands. For several decades, the number of yaks has decreased, and the management strategy of yak herding has been altered due to the influence of substantial changes in both the social environment and their livelihoods. We conducted field surveys on yak herding in the south of Mustang District from 2012 to 2016 to examine the recent shift in management strategy and practice. The surveys were focused on fifteen yak owners and their herdsmen who lived …

Exploring Institutional Complementarity And Social Thresholds Of Mobility In Pastoral Social-Ecological Systems In Mongolia, Ulan Kasymov, Irene Ring

IGC Proceedings (1977-2023)

Biodiversity continues to decline worldwide, affecting dryland ecosystems that are of significant importance for global biodiversity conservation. Accelerated by climate change, undergoing transformations have been pushing the entire social-ecological system across ecological and social thresholds. Particularly, the decline of pastoral mobility in Mongolia is of great concern, as flexible responses to the dynamic environment are crucial for the sustainability of drylands’ ecosystems. Responding to this concern, Mongolian policymakers design new pasture use and conservation policies. However, the policies might be ineffective in preventing systems from crossing the thresholds, unless policy implementation succeeds in systematically shaping the perceptions of a critical …

Action Plan For The International Year Of Rangelands And Pastoralists (Iyrp): The Case For The United States, Canada, And Mexico, Barry Irving, Larry Howery, Jürgen Hoth, Jess Peterson

IGC Proceedings (1977-2023)

The GAP analysis (A Case of Benign Neglect: Knowledge gaps about sustainability in rangelands and pastoralism) points to several gaps that are relevant to the US, Canada and Mexico. North American rangelands span the ecological continuum of polar to hot deserts and arid to humid climates that exhibit highly variable ecological and forage production potential across time and space. Although there is a great deal of rangeland research, extension, and inventory capacity in all three countries, a weak link is the dissemination of information to North American pastoralists (conventionally referred to as ranchers or producers). Although the extension system in …

Rangelands And Pastoralism Of The Middle-East And North Africa, From Reality To Dream, N. Naghizadeh, Hossein Badripour, Mounir Louhaichi, M. Gamoun, Maryam Niamir-Fuller

IGC Proceedings (1977-2023)

The Middle East and North Africa (MENA) is a vast area covering 20 countries from western Asia to North Africa, with nearly 9,000,000 Km2 and 303 million hectares of total rangelands. Rangelands play an essential role in supporting people's livelihoods and food security. Mobile pastoralism is the most viable and resilient form of production and land use in the fragile drylands of MENA. The region's governments have considered mobile pastoralism as backwards mainly because it was difficult to deliver mobile services to them. They designed various policies that were not in harmony with pastoralists' customary rules and norms and severely …

Priority Themes And Issues For The International Year Of Rangelands And Pastoralists, Maryam Niamir-Fuller, James T. O’Rourke, Barbara Hutchinson

IGC Proceedings (1977-2023)

The objective of the International Year of Rangelands and Pastoralism (IYRP) is to increase world-wide awareness and recognition of the value and contributions of rangelands and pastoralists. The aim is to influence country policies, legislation, and programs; and to encourage development, research, extension and educational initiatives that will lead to sustainability of rangelands and pastoral/livestock systems. Although each country should decide on how they would celebrate the IYRP, the adoption of a global framework of 12 monthly themes will help to a) provide suggestions and ideas, b) highlight urgent and topical issues, and c) show how pastoralism and rangelands across …

Priority Areas For Action And Research On Pastoralism And Rangelands In Eastern Africa, M. O. Odhiambo

IGC Proceedings (1977-2023)

There is an element of irony around pastoralism and research in Eastern Africa. While it is one of the most researched production and livelihood systems, pastoralism is also the least understood by policymakers and development actors, with discussions about its importance characterized by significant gaps in knowledge. What is more, policy actors have difficulties accessing empirical data specific to pastoralism and rangelands in a form that allows well-founded decision-making on policy and action. Most available data tend to be out of date and not disaggregated with reference to pastoralism and rangelands. As a result, much of the discourse around pastoralism …

Rangelands And Pastoralism In Central Asia And Mongolia: Challenges And Perspectives, T. Ulambayar

IGC Proceedings (1977-2023)

Livestock herding contributes 10-45% of national GDPs across the Central Asia and Mongolia (CAM) region while supporting the livelihood of nearly one-third of the region’s population. Over 171 million herds graze the region's rangelands, occupying 65-73% of the territories in Central Asia (CA) and Mongolia. Traditional pastoralism has been affected dramatically by climate change. For the last decades, the annual mean air temperature has risen two to three times higher than the global average in CA and Mongolia respectively. Annual precipitation has a decreasing trend over the same period, causing increased aridity, a decline in lakes and rivers leading to …

International Year Of Rangelands And Pastoralists (Iyrp) History, Process, Priority Themes And Way Forward, James T. O’Rourke, Maryam Niamir-Fuller, Barbara Hutchinson

IGC Proceedings (1977-2023)

The road towards the declaration of an IYRP by the United Nations has been long and rocky, perhaps mirroring the relative lack of understanding by some governments of the importance of rangelands and pastoralists for a sustainable world, compared to the focus on other sectors such as forest or cropland sustainability. The idea was first discussed at the International Rangeland (IRC) and Grassland (IGC) Congress held in Hohhot, China in 2008. The creation of an International Support Group (ISG) in 2015 helped to provide a stronger rational and the integration of social dimensions. This has led to a growing partnership …

Management Changes And Strategies To Improve The Environmental Services From Grasslands In Northern China And Mongolia, David R. Kemp, J. Addison, K. Behrendt, G. Udval, D. Lkhagvaa, Guodong Han, Zhiguo Li, P. Li

IGC Proceedings (1977-2023)

The grasslands of Mongolia and northern China are part of the vast Eurasian grasslands that extend from east Asia to eastern Europe, with many common problems. Grassland degradation and herder livelihoods in the steppe regions of China and Mongolia are widely acknowledged as major issues that need to be improved. The core problem is too many animals are now grazing grasslands, initially driven by significant policy changes, and decisions that assumed more animals would lift herder incomes. Problems are accentuated by poorly defined property rights over the land. The effectiveness of current Government Programs aimed at reducing grazing pressures has …

Implications Of Herder Attitudes For Stocking Rates In China And Mongolia, Yanting Yin, Ping Li, David R. Kemp

IGC Proceedings (1977-2023)

Over-grazing of the grasslands in China and Mongolia is a common problem. Herders typically aim to increase their animal numbers to then hopefully, improve their status and incomes. Various studies have shown that stocking rates often need to be halved to restore grasslands to a sustainable state. Governments have been enacting policies to achieve a reduction in stocking rates, especially in China. However, in both countries, herders have freedom to set their own stocking rates. A survey was done of ~900 herders in Inner Mongolia, on the five main grassland types, to define their styles, attitudes and intentions for stocking …

The State Of Grasslands Across Inner Mongolia And Mongolia, Guodong Han, David R. Kemp, Bulgamaa Densambuu, Zhiguo Li, Cuiping Gao, Zhongwu Wang, Zhiqiang Qu, Mengli Zhao, G. Udval, Qian Wu, Naya, Linxi Hu

IGC Proceedings (1977-2023)

Grasslands across Inner Mongolia and Mongolia, with their long history of nomadic livestock grazing, are very important natural resources for animal husbandry and environmental services. The main types of grasslands are meadow steppe (forest steppe), typical steppe (steppe) and desert steppe. Most of the grasslands are degraded due to over-grazing, which reduces animal production and the values of environmental services. Overgrazing decreases plant production, species biodiversity, ecosystem stability, soil fertility & structure, and lowers animal productivity leading to reduced household incomes. In pastoral areas across Inner Mongolia and Mongolia, degraded grasslands can be rehabilitated by better managing stocking rates. Our …

Knowledge About And Knowledge With: Contributions From Feminist Research To Knowledge Co-Production For Pastoral Systems, F. Ravera, María Fernández-Giménez, E. Oteros-Rozas

IGC Proceedings (1977-2023)

Globally, the gender dynamics of rangeland social-ecological systems have received scant attention. Further, research paradigms, methods and methodologies that leave little room for equitable engagement with research participants and genuine action-oriented research-practice partnerships dominate in pastoralist/rangeland studies. Our research is informed by a feminist philosophy of science and based on decolonial and feminist political ecology studies that focus on gendered science and knowledge production. Feminist research calls for reflection on who produces knowledge and how such knowledge is used and shared. Feminist practices such as reciprocity, care, and positionality, cultivate awareness of the power dynamics embedded in the research process …

Women’S Empowerment For Demographic Issues And Conflicts In African Pastoralist Societies, M. R. Cevallos, P. Manzano

IGC Proceedings (1977-2023)

Widespread conflict is a recurring issue in African pastoralist societies. While its roots are debated, there is a missing link with prevailing poverty among communities and particularly among women. We here apply a gender perspective to establish a hypothesis on the role of women in pastoralist conflicts.

The existing polygynic system establishes a violent frame for pastoralist women, who would be sold at increasingly early ages to provide in turn enough resources for furnishing the dowry needed by their brothers. The control on them would thereby be transferred from their own families to their husband and his family, where they …

Brazilian Pampa Rangelands: Challenges In The Face Of Soybean Expansion, J. G. Moriera, R. G. Maciel, Paulo D. Waquil, J. F. Tourrand

IGC Proceedings (1977-2023)

The Pampa biome extends throughout the Uruguayan territory, part of Brazil, Argentina and Paraguay. It is characterized by being a natural pastoral ecosystem, in which livestock represents the best option for sustainable use for food production purposes, and favors the conservation of its rangelands. In addition to contributing to the conservation of natural pastures, it was along with livestock activities that the gaucho's way of life was developed. However, the cultivation of soybeans and eucalyptus plantations in the Pampa in all its extension is the localized version of the global dynamics of valuing the production of agricultural commodities affecting various …

Assessment Of Thermographic Imaging Systems On Small Unmanned Aerial Systems (Suas) To Identify Artificial Grassland Bird Nests, L. M. Hearon, J. M. Morrison

IGC Proceedings (1977-2023)

Grassland bird populations can be good indicator species of ecosystem health. However, their populations are declining at greater rates than any other group of birds. A well-established method of monitoring rapidly disappearing bird populations is by locating and identifying active nests. Studies quantifying grassland birds tend to have low statistical power due to low sample sizes, high labor costs, and high levels of disturbance - associated with difficulty finding nests. However, advances in small unmanned aerial systems (sUAS) and thermographic imaging technologies have the potential to improve efficiency and accuracy of locating nests, while causing minimal disruption. Early research has …

Bird Community Responses To Rest-Rotation Grazing In Western Canada's Grasslands, T. F. Döbert, J. A. Randall, M. Iravani, E. W. Bork, M. S. Boyce

IGC Proceedings (1977-2023)

Western Canada’s native grasslands support high levels of avian diversity including both resident and migrant species. Many grassland specialist bird populations, however, are in serious decline due to widespread habitat loss resulting from agricultural conversion and adverse land management. As the primary use on remaining grasslands, cattle grazing largely determines the availability and quality of bird species’ habitat, depending on the timing, intensity, and frequency of livestock use. While adaptive multi-paddock grazing (AMP, a short duration, high-intensity grazing system that prioritises plant recovery between grazing events) is growing in popularity, comprehensive assessments of bird diversity in relation to AMP grazing …

Tree Legumes As Sustainable Ecosystem Services In Livestock Systems, James P. Muir, C. E. Cooper, V. Corriher-Olson

IGC Proceedings (1977-2023)

Arboreal legumes provide multiple uses in pastures and rangelands. Trees directly and indirectly feed, house, doctor, and warm humans at minimal environmental cost through forage (fodder), timber, biofuel, medicines, as well as edible leaves, pods, and seeds. Leguminous trees, because they foster biological nitrogen fixation (BNF) and acquire deep-soil nutrients and moisture, compete less with herbaceous plants for shallow-horizon soil moisture and nutrients. Their ecosystem services (ES) are generally less obvious and quantifiable. These include converting CO₂ to sequestered C and released O₂ in N-poor soils where trees without BNF do not thrive. Other ES include shade for …

Conservation Innovation In Pastoral Lands Around The Globe: Challenges, Lessons And Opportunities, R. S. Reid

IGC Proceedings (1977-2023)

Pastoralists and ranchers have a long history of sustained management of rangelands around the world. Several decades ago, some pastoralists and ranchers started new alliances with environmental organizations, businesses and government agencies to diversify their approaches to land management to include what can be called ‘conservation’. These efforts highlight conserving aspects of rangeland ecosystems, but often have an equal or greater emphasis on supporting pastoral livelihoods and culture. This paper asks: What types of innovations are pastoralists now pursuing in ‘conservation’? How are these innovations performing?

This paper provides a synthesis of some of the types of conservation innovations being …

Revitalizing Pastoral Calendars: Snowcover, Seasonal Migration, And Pastoral Decisions From Alai Valley Of Kyrgyzstan, Daler Kaziev

IGC Proceedings (1977-2023)

Herding practices among semi-settled agropastoral communities in the Pamir-Alai Mountains of Central Asia are subject to seasonal variations, making climate change adaptation urgent. Livestock keeping is an essential part of the local economy in the Alai Valley of Kyrgyzstan. Focusing on collaborative efforts to develop traditional ecological calendars in the village of Sary-Mogol, Alai valley, Kyrgyzstan, this study seeks to demonstrate the relationship between snow and herding practices.There are four distinct seasonal migration patterns such as baarloo spring, summering jailoo, autumn kyzdoo and wintering kyshtoo. The relationship between these migration patterns and biophysical events such as snow accumulation …

The Response Of Selected Temperate Forages To Increasing Summer Drought Conditions And High Summer Temperatures In Northern Victoria, Australia, M. E. Rogers, A. R. Lawson, K. B. Kelly, W. J. Wales, J. L. Jacobs

IGC Proceedings (1977-2023)

In the dairy region of northern Victoria, Australia, the performance of temperate perennial dairy pastures is often poor over summer due to a combination of high temperatures and limited water availability that can restrict dry matter production and plant survival. A series of field experiments examined the effects of heat and restricted irrigation (as a consequence of drought) on the growth and nutritive characteristics of selected forage species, and whether survival under experimental conditions was influenced by plant genotype, irrigation and grazing management strategies, as well as endophyte presence. The major focus was on perennial ryegrass.

Detailed sampling of perennial …

The Effect Of Calcium Ions On Mechanosensation And Neuronal Activity In Proprioceptive Neurons, Devan E. Atkins, Kimberly L. Bosh, Grace W. Breakfield, Sydney E. Daniels, Makayla J. Devore, Hailey E. Fite, Landys Z. Guo, Danielle K. J. Henry, Alana K. Kaffenberger, Katherine S. Manning, Tatum E. Mowery, Cecilia L. Pankau, Nyla Parker, Malina E. Serrano, Yamaan Shakhashiro, Hannah N. Tanner, Ruth. A. Ward, Aubrey H. Wehry, Robin L. Cooper

Biology Faculty Publications

Proprioception of all animals is important in being able to have coordinated locomotion. Stretch activated ion channels (SACs) transduce the mechanical force into electrical signals in the proprioceptive sensory endings. The types of SACs vary among sensory neurons in animals as defined by pharmacological, physiological and molecular identification. The chordotonal organs within insects and crustaceans offer a unique ability to investigate proprioceptive function. The effects of the extracellular environment on neuronal activity, as well as the function of associated SACs are easily accessible and viable in minimal saline for ease in experimentation. The effect of extracellular [Ca²⁺] on …

Gestational Diabetes Triggers Postpartum Cardiac Hypertrophy Via Activation Of Calcineurin/Nfat Signaling, Nirmal Verma, Sarah Srodulski, Sathya Velmurugan, Amanda Hoskins, Vivek K. Pandey, Florin Despa, Sanda Despa

Pharmacology and Nutritional Sciences Faculty Publications

Population-based studies identified an association between a prior pregnancy complicated by gestational diabetes mellitus (GDM) and cardiac hypertrophy and dysfunction later in life. It is however unclear whether GDM initiates this phenotype and what are the underlying mechanisms. We addressed these questions by using female rats that express human amylin (HIP rats) as a GDM model and their wild-type (WT) littermates as the normal pregnancy model. Pregnant and two months postpartum HIP females had increased left-ventricular mass and wall thickness compared to non-pregnant HIP females, which indicates the presence of concentric hypertrophy. These parameters were unchanged in WT females during …
