Faculty, Staff and Students Publications

Chagas disease, caused by the protozoan Trypanosoma cruzi, is a significant challenge for canine health, with limited diagnostic tools. This study assessed the performance of a novel Tc-24 recombinant antigen ELISA compared to three commercial diagnostic tests on 70 serum samples from kennel dogs in Texas. The Tc-24 ELISA demonstrated high sensitivity (87.5%) and specificity (91.2%) compared to Indirect Fluorescent Antibody (IFA) testing, with significant differences in Tc-24 optical density (OD) between positives and negatives (0.607 vs. 0.089, p < 0.001). When compared to Chagas Stat-Pak (SP), Tc-24 ELISA showed sensitivity and specificity values of 82.1% and 86.7%, respectively (p < 0.001). For Chagas Detect Plus (IB), the assay achieved a sensitivity of 80.0% and specificity of 93.1% (p < 0.001). Spearman correlation analysis revealed significant associations between Tc-24 OD and SP (r = 1.0, p = 0.0167), IB (r = 0.9, p = 0.0833) and IFA (r = 0.6273, p = 0.044). Elevated immunochromatographic values in commercial kits (SP or IB) correlated with Tc-24 OD (1.17 vs. 0.039, p < 0.001), achieving 100% sensitivity and 95.8% specificity based on positive results from commercial kits. These findings suggest that Tc-24 ELISA is a reliable and accurate serological tool for diagnosing T. cruzi infection in dogs, with the potential to enhance diagnostic capabilities in veterinary medicine.

Consumption Of Negative Media Content Mediates The Association Between Levels Of Trauma Exposure And Insomnia Severity In Hispanic Young Adults, Michiyo Hirai, Laura L. Vernon

Psychological Science Faculty Publications

Research has shown that individuals who have experienced traumatic events are at greater risk of developing severe insomnia than those without trauma. Further, according to the stress sensitization hypothesis, victims of multiple traumas, compared to those who have experienced a single trauma, are particularly vulnerable to severe insomnia. One potential mechanism underlying the association between trauma experiences and insomnia is media exposure. Although avoidance behaviors are symptoms of posttraumatic stress, victims of traumas also demonstrate attentional bias toward threats and difficulty disengaging attention from threats. These cognitive tendencies may result in heightened vigilance to negative media content, particularly trauma-related content, …

Dentistry And The Law: We Forgot To Renew Our Employment Agreement —Now What?, Daniel Schulte Jd

The Journal of the Michigan Dental Association

This Q&A addresses the legal implications when a fixed-term dental employment agreement expires without formal renewal. MDA Legal Counsel explains that if the employee continues working under the same conditions, an oral employment agreement is implicitly formed, retaining the original terms but becoming terminable without cause by either party at any time. A key consequence is that any post-termination provisions, such as a covenant not to compete, begin their restricted period countdown from the original agreement's expiration date, regardless of continued employment. The article advises that it's generally more practical for employment agreements to simply state that the term continues …

It also highlights the critical considerations of data privacy (HIPAA compliance) and the enduring value of the relationship-driven nature of dentistry. Ultimately, the most successful dentists will be those who combine emerging technologies …

Staff Matters: Can I Google Someone Before I Decide To Hire Them?, Jodi Schafer Sphr, Shrm-Scp

The Journal of the Michigan Dental Association

This Q&A addresses the practice of using Google searches to vet job applicants, cautioning that while it provides public information, it can also inadvertently reveal protected classifications (e.g., religious beliefs, race, age), making hiring decisions based on such information illegal and discriminatory. The article advises conducting internet searches after a screening interview to first establish a candidate's qualifications, which provides a defensible rationale for hiring choices. It is crucial to obtain a signed release from the applicant before conducting any background checks to ensure compliance with laws like the Fair Credit Reporting Act. The author also notes that requiring access …

Enhancing Preparedness: A Genetic Study Of Sar-Cov-2 And Other Microbial Public Health Threats In Wastewater From A College Town, Christian N. Hutchinson

Master's Theses

Problem

The SARS-CoV-2 (COVID-19) pandemic revealed both the systemic vulnerabilities of our healthcare system as well as the importance of timely, localized data for informing public health responses. Traditional testing approaches were essential but often failed to capture the full extent of viral spread, especially in those with mild or asymptomatic conditions that relied on at home testing. This underreporting hindered effective allocation of resources and made developing effective intervention strategies difficult. We also realized the potential for wastewater surveillance to be applied to tracking antimicrobial resistance gene markers. Taken together, this approach should have important implications for improving public …

Older Adults And Financial Exploitation, Aaron Li, Natalie Galucia, Cal J. Halvorsen

Harvey A. Friedman Center for Aging

The National Adult Protective Services Association defines elder financial exploitation as misuse, mishandling, or exploitation of an older adult’s property, possession, or assets. These actions often occur without consent and are typically carried out through false pretense, undue influence, coercion, or manipulation.

Ageism In Employment, Aaron Li, Natalie Galucia, Cal J. Halvorsen

Harvey A. Friedman Center for Aging

The World Health Organization defines ageism as stereotypes, prejudice, and discrimination directed at individuals based on their age. As people remain in the labor force longer, they are increasingly exposed to ageist attitudes and discrimination. Ageism often manifests through negative assumptions about older workers’ abilities, adaptability, and value in the workplace. Older workers are frequently perceived as less competent, resistant to new technology, inflexible, or physically and mentally less capable.

Mental Health Challenges In Later Life, Sophie Mauk, Michele Dinman, Natalie Galucia, Cal J. Halvorsen

Harvey A. Friedman Center for Aging

Although older adults are less likely to be diagnosed with mental health challenges than younger adults, Americans over the age of 65 have experienced the greatest growth in new diagnoses — an increase of 57% between 2019 and 2023. By 2023, about 1 in 7 adults age 51 and older had received mental health diagnoses, including major depressive, generalized anxiety, adjustment, bipolar, and mood disorders. However, older adults are less likely to receive treatment than younger people. At the same time, older adults may also misuse substances such as alcohol, tobacco, cannabis, and prescription and nonprescription medications. Americans age 75 …

Local Identity In The Lives Of The Fathers Of Mérida: When Ethnicity And Religion Aren’T The Point, Erica Buchberger

History Faculty Publications

While scholarship on early medieval Europe often centers ethnicity or religion over other forms of identity, they were not always the most relevant form of identification for contemporaries. In the Lives of the Fathers of Mérida (late sixth-early seventh century), ethnic and religious identity were actually deployed to construct a local identity around the space and people of the city. This article explores how the text did so by closely analyzing terms used and their context, and by applying social scientific theories of boundary construction to illuminate the strategies of identification behind it. It argues that such an approach …

“Lead”Ing Industrial Science: Studying Occupational Lead Poisoning In The Early 20th Century, Rebekah E. Dreyer-Rowe

Master's Theses and Capstones

Lead was essential to the creation and coalescence of industrial hygiene as a discipline in the United States from its early days in the 1910s through the 1930s when the first professional associations of industrial hygiene were formed. In the early years, Alice Hamilton was central to the burgeoning field, and her seminal study on lead poisoning in Illinois industries thrust both her and her methods into the spotlight. Industrial hygienists of her generation followed her methods and came away with similar conclusions: that occupational diseases were rampant in the US, even if few people were studying them. In the …

The Catholic Terror: A History Of The Baptism Of Enslaved Populations In The Colonial Protestant Atlantic, Benjamin Taylor

Master's Theses and Capstones

In the mid-eighteenth century, the number of enslaved people baptized into the Protestant church increased in the British Atlantic. Many historians have argued that the increase occurred by highlighting scriptural debates between slave owners and missionaries. Many slave owners believed that being Christian was synonymous with being free, but missionaries staunchly opposed this view. To change slave owners’ minds, missionaries argued that Protestantism made enslaved people “better behaved.” However, I believe that the reason slave owners became more willing to baptize enslaved people had more to do with external factors. The British were surrounded by many antagonistic Native tribes and …
