Background: Long coronavirus disease (COVID), which affects an estimated 44.69-48.04 million people in the United States, is an ongoing public health concern that will persist as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continues to spread.

Methods: We developed a computational simulation model representing the clinical course, health effects, and associated costs of a person with long COVID.

Results: Simulations show that the average total cost of a long COVID case can range from $5084-$11 646 (assuming symptoms only last 1 year) with 92.5%-95.2% of these costs being productivity losses. Therefore, the current number of long COVID cases could cost …

Savoring The Seaweeds: Health And Sustainability Through Creole Foods, Roxanna Belleau

Ursidae: The Undergraduate Research Journal at the University of Northern Colorado

Incorporating kelp into American diets offers a promising avenue for enhancing nutrition and environmental sustainability. Despite its nutritional richness and ecological benefits as a "superfood" and carbon sink, cultural resistance presents a barrier to its widespread acceptance. This study delves into kelp's nutritional content and ecological advantages, exploring its potential to reshape dietary habits. Drawing insights from interviews and surveys, cultural norms emerge as a significant obstacle to kelp's integration into American cuisine. Strategies inspired by successful culinary adaptations, such as creole dishes, are proposed to navigate these challenges and shift societal perceptions. Furthermore, integrating kelp into familiar American foods …

Weaning Beef Calves, David Secrist

All Current Publications

Weaning a beef calf is likely the most stressful event in the animal’s life. Future growth and reproductive performance can be compromised by health challenges encountered through the weaning process. Consequently, proper management aimed at reducing stress and preparing the beef animal for the next stage of production is critical to reach its genetic potential. Proper management involves applying good animal husbandry techniques, using sound science in developing health and feeding protocols, and implementing low-stress animal handling practices.

The Impact Of The Covid-19 Pandemic And Race On Access To Maternal Healthcare Services For Patients Based On Insurance Status, Trishana Monlyn

Walden Dissertations and Doctoral Studies

Due to insurance status, COVID-19 has restricted how and when patients can access healthcare providers. In the health services community, examining obstetric care services during the coronavirus outbreak was important because it increased awareness about how changes to maternal healthcare access affect the health of the mother and unborn child during a pandemic. The theories and/or concepts that grounded this study include the intersectionality theory, which examined the connections between social groups and systems as individuals try to access health services based on health insurance reform, depending on their race. The purpose of this study was to determine if there …

Plants, Soils and Climate Student Research

Alfalfa (Medicago sativa L.) is a globally vital forage crop valued for its perennial growth and multiple annual harvests. A breeding effort is underway to improve the crop for productivity and persistence against biotic and abiotic stresses using “creeping rootedness,” a trait where plants exhibit horizontal root growth, similar to rhizomes, with increased vegetative ground surface area. In this study, we genotyped a breeding population of 648 alfalfa lines segregating for creeping rootedness using the 3K DArTag marker panel to identify trait-associated genomic loci and evaluate the feasibility of genomic prediction to accelerate breeding cycles. Using genome-wide association studies …

Social Forestry As Solution To Agrarian Conflicts? A Case Study Between Oil Palm Smallholders And Industrial Plantations In Jambi, Indonesia, Muhammad Reza Halomoan, Arya Hadi Dharmawan, Satyawan Sunito

Forest and Society

Extraction activities across Indonesia have caused drastic changes to forest ecologies. The Indonesian government responded to this through a policy of Industrial Plantation Forest concessions, which were given to the private sector in the hopes of overcoming damages from forest extraction activities while at the same time utilizing unproductive forest land. However, this policy does not pay attention to the existence of people who de facto control and use the land and has triggered new conflicts around agrarian claims based on different interpretations of land rights. In an effort to resolve conflicts, the government has implemented a community-based forest area …

Soil-transmitted helminths (STHs) are intestinal parasites that affect over a billion people worldwide. STH control relies on microscopy-based diagnostics to monitor parasite prevalence and enable post-treatment surveillance; however, molecular diagnostics are rapidly being developed due to increased sensitivity, particularly in low-STH-prevalence settings. The genetic diversity of helminths and its potential impact on molecular diagnostics remain unclear. Using low-coverage genome sequencing, we assess the genetics of STHs within worm, faecal, and purified egg samples from 27 countries, identifying differences in the genetic connectivity and diversity of STH-positive samples across regions and cryptic diversity between closely related human- and pig-infective species. We …

Measuring And Mapping Spatial Distributions Of Soil Lead Concentrations Across An Urban-To-Rural Gradient In Chicagoland, Lulia Woldemicael, Andrea Stoeva

DePaul Discoveries

Lead (Pb), a highly toxic chemical has found its way into many aspects of our communities through a plethora of different pathways such as paint, gasoline, and industrial activity. Exposure to lead poses harmful risks to all age groups as a higher blood lead level is associated with higher mortality. Although actions have been taken to eliminate lead from the atmosphere, it remains in the environment, especially accumulating in urban areas where the use of automobiles and highly industrialized landscapes are prevalent. This study examines the soil lead concentrations along an urban-to-rural gradient connecting Humboldt Park, Skokie, and Buffalo Grove, …

The Thai Journal of Veterinary Medicine

The hippopotamus, commonly known as the hippo, is classified into two extant species: the common hippopotamus (Hippopotamus amphibius) and the pygmy hippopotamus (Choeropsis liberiensis). Pygmy hippos are fascinating creatures native to the forests and swamps of West Africa. Their survival is increasingly threatened by habitat loss resulting from agricultural expansion and urban development. As the population declines, zoological institutions play a crucial role in conservation by acting as genetic reservoirs and promoting public awareness of wildlife and environmental protection. “Moo Deng”, a pygmy hippo, whose name in Thai has gained international recognition, represents a notable success …
