Redefining Burnout: Exploring Common Conceptualizations And The Neurophysiology Of Chronic Stress To Establish An Integrated Allostatic Model, Danny A. Guzzi

Dissertations

Burnout is a widely researched stress-related phenomenon associated with numerous adverse outcomes for employees and organizations. Unfortunately, burnout is not well understood and research to this point has been flawed due to a lack of consensus on the definition, dimensionality, and context of the construct. Prevalent conceptualizations of burnout have been criticized for being arbitrarily developed without solid theoretical foundation and for failing to clearly distinguish burnout from depression or other work-related conditions such as compassion fatigue, secondary traumatization, and vicarious traumatization. The current project first examines relevant literature to identify commonalities among prevalent burnout conceptualizations. Then relevant stress research …

Vapor Delivery Of Plant Essential Oils Alters Pyrethroid Efficacy And Detoxification Enzyme Activity In Mosquitoes, Scott T. O'Neal, Ellis J. Johnson, Leslie Catherine Rault, Troy D. Anderson

Department of Entomology: Faculty Publications

The use of synthetic insecticides to limit the spread of mosquito-borne disease faces a number of significant challenges, including insecticide resistance, concerns related to the environmental impact of widespread insecticide use, as well as slowed development of new insecticide chemistries. One important alternative to broadcast insecticides is the use of personal protection strategies to limit contact with vector species, including the use of spatial repellents that can employ synthetic pyrethroids or botanical products to effect control. A currently underexplored area of research involves the investigation of botanical products for their potential to serve as insecticide synergists when delivered as a …

Improving Access To Clean Water In Rural Ecuador: The Connection Between Willingness To Pay And Population Health, Micalea Leaska

Capstone Collection

Climate change is affecting social and environmental determinants of health through access to safe drinking water, safely managed sanitation systems, and access to health care services and the ability for individuals to break free from unsuitable circumstances. Ecological disturbances such as those caused by climate change can cause a shift in host vectors or a change in habitat that results in a greater likelihood of the pathogen coming in contact with humans. Water, sanitation, and hygiene (WASH) services and their accessibility to populations can directly impact a community’s vulnerability to diseases and limiting factors to increase economic growth. If rural …

Elucidating The Role Of Oxygen And Biotype In The Environmental Persistence Of Vibrio Cholerae, Amy M. Freiberg

Honors Undergraduate Theses

Vibrio cholerae is a natural inhabitant of aquatic environments and serves as the etiological agent for the severe diarrheal disease, cholera. Cholera epidemics follow a regular seasonal pattern, which account for tens to hundreds of thousands of deaths in a given year. V. choleraenaturally persist between epidemics through entry into a dormant state known as viable but nonculturable (VBNC). Research has shown that V. choleraein this VBNC state experience drastic morphological and metabolic changes, which serve as survival mechanisms until environmental conditions become suitable again. The natural marine ecosystem that V. cholerae inhabitis comprised of a complex …

Multiple Regression Models To Analyze Length Of Hospitalization Due To Nosocomial Infections In U.S. Hospitals, Ernest M. Oleksy

The Downtown Review: An Interdisciplinary Journal Written and Peer-Reviewed by Mandel Honors College Students at Cleveland State University

Nosocomial diseases are a serious concern and detriment to hospitals’ abilities to provide appropriate patient care. Bearing this in mind, an effort must be made to determine whether infection surveillance and control programs have reduced the rates of nosocomial infection at U.S. hospitals. The data that were studied were obtained as part of the Study on the Efficacy of Nosocomial Infection Control (SENIC) and used to develop a model of what variables most contribute to a patient’s length of stay at the Cleveland Clinic (Quade et al, 1980).

Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender

Student Theses 2015-Present

This paper aims to shed light on the dissonance caused by the superimposition of Dominant Human Systems on Natural Systems. I highlight the synthetic nature of Dominant Human Systems as egoic and linguistic phenomenon manufactured by a mere portion of the human population, which renders them inherently oppressive unto peoples and landscapes whose wisdom were barred from the design process. In pursuing a radical pragmatic approach to mending the simultaneous oppression and destruction of the human being and the earth, I highlight the necessity of minimizing entropic chaos caused by excess energy expenditure, an essential feature of systems that aim …

The Role Of Stress In The Pathogenesis And Maintenance Of Obsessive-Compulsive Disorder, Thomas G. Adams, Benjamin Kelmendi, C. Alex Brake, Patricia Gruner, Christal L. Badour, Christopher Pittenger

Psychology Faculty Publications

Individuals with obsessive-compulsive disorder often identify psychosocial stress as a factor that exacerbates their symptoms, and many trace the onset of symptoms to a stressful period of life or a discrete traumatic incident. However, the pathophysiological relationship between stress and obsessive-compulsive disorder remains poorly characterized: it is unclear whether trauma or stress is an independent cause of obsessive-compulsive disorder symptoms, a triggering factor that interacts with a preexisting diathesis, or simply a nonspecific factor that can exacerbate obsessive-compulsive disorder along with other aspects of psychiatric symptomatology. Nonetheless, preclinical research has demonstrated that stress has conspicuous effects on corticostriatal and limbic …

Of Rats And Men, Thomas S. Walsh

Capstones

This capstone is a data-driven investigation into New York City's rat problem. By using publicly available government data to map rat activity in NYC, I identified several socio-economic variables that correlate with rat populations at the community district, borough, and city-scale. I used these findings (mainly that rat problems are linked to lower incomes) as the basis of an investigation, which includes interviews with residents, experts, and city officials. Prof. Bobby Corrigan, urban rodentologist and formerly with the NYC Department of Health criticizes the city's efforts for the first time on the record.

Behavioral Ecology And Associated Virology Of Mosquito-Host Interactions In Southern California, Oliver Eshun

Loma Linda University Electronic Theses, Dissertations & Projects

Elucidating characteristics of mosquito-host interactions are critical for understanding the ecology and epidemiology of mosquito-borne diseases. In this dissertation, I conducted three studies to explore potential mosquito-host interactions and associated virus infection rates. I first demonstrated that mosquito captures at CO2-baited traps decreased most markedly with height above ground, and also decreased with distance from water at a riparian area but not at an open water source lacking a vegetated border. Birds might therefore prefer elevated nests or roosts to avoid mosquitoes. The second study examined the anti-mosquito behaviors of budgerigars (Melopsittacus undulatus) in a laboratory study. The birds defended …

Determining The Protective Effects Of Quercetin Against Cadmium Toxicity In Human Embryonic Kidney Cells, Caroline N. Smith

Undergraduate Theses

Cadmium is a toxic industrial and environmental pollutant found in groundwater, air, soils, food and cigarettes. Chronic intake of low levels of cadmium has been shown to result in renal dysfunction due to cell death which can occur via apoptosis as well as necrosis. Previous studies have shown that plant extracts containing quercetin, a flavonoid found in many fruits and vegetables, protect against cadmium toxicity in rat liver hepatocytes. To determine if quercetin may have a protective effect in a cadmium-treated human embryonic kidney cell line, HEK-293 cells were treated using concentrations of cadmium chloride from 10 to 50 μM …

P35. Investigating The Effect Of Maternal Immune Activation On Sensory Filtering, Social Behaviour And Attention, Faraj Haddad

Western Research Forum

Background

Altered brain development is associated with many neuropsychiatric disorders like Autism Spectrum Disorder (ASD) and schizophrenia. Environmental insults can interfere with neurodevelopment, and a prominent example is maternal infection during pregnancy. Epidemiological studies show that children born to mothers who were infected during pregnancy display a higher risk of developing ASD and schizophrenia, and this effect is mainly due to the maternal immune response. Polyinosinic-polycytidilic acid (Poly I:C) is a double stranded RNA molecule that mimics viral markers and elicits an immune response. When injected in pregnant rodents, this model produces offspring that exhibit core symptoms of ASD and …

Ukraine : Papillary Thyroid Cancer, Elizabeth Paris

Global Public Health

Ukraine is a middle- to low- income country run by a semi-presidential republic, after the banning of the Communist party in the early 1990's. While the nation faces various internal and external challenges, including unemployment rates and war with Russia, Ukraine also continues to face a major public health issue that originated in the 1980's. In 1986, an explosion was triggered at the nuclear power plant in Chernobyl, Ukraine. The explosion released radioactive iodine into the ground, water, and air, and it was discovered soon after that this had a long-lasting effect on health. It has been observed that rates …

Vinyl Chloride-Diet Interactions In Liver Disease : Potential Roles Of Autophagy And Energy Management., Anna L. Lang

Electronic Theses and Dissertations

Vinyl chloride (VC) is a prevalent environmental toxicant that has been shown to cause liver injury at high, occupational exposures. However, most studies have not addressed interactions of low doses with risk-modifying factors. This study aims to explore low-level VC metabolite exposure interactions with other potential risk-modifying factors and their effect on underlying liver disease. We examined sub-hepatotoxic effects of a VC metabolite (chloroethanol, CE) in two murine models of liver injury using ethanol and lipopolysaccharide (LPS). In both, CE significantly enhanced liver injury when compared to either ethanol or LPS alone. Previous studies have shown an increase in mTOR …

Hdac6 Inhibition Prevents Tnf-Α-Induced Caspase 3 Activation In Lung Endothelial Cell And Maintains Cell-Cell Junctions, Jinyan Yu, Mengshi Ma, Zhongsen Ma, Jian Fu

Center for Research on Environmental Disease Faculty Publications

Pro-inflammatory mediators such as TNF-α induce caspase activation in endothelial cells, which leads to degradation of cellular proteins, induction of apoptotic signaling, and endothelial cell dysfunction. New therapeutic agents that can inhibit caspase activation may provide protection against inflammatory injury to endothelial cells. In the present study, we examined the effects of selective histone deacetylase 6 (HDAC6) inhibition on TNF-α induced caspase 3 activation and cell-cell junction dysfunction in lung endothelial cells. We also assessed the protective effects of HDAC6 inhibition against lung inflammatory injury in a mouse model of endotoxemia. We demonstrated that selective HDAC6 inhibition or knockdown of …

Hexavalent Chromium Induces Malignant Transformation Of Human Lung Bronchial Epithelial Cells Via Ros-Dependent Activation Of Mir-21-Pdcd4 Signaling, Poyil Pratheeshkumar, Young-Ok Son, Sasidharan Padmaja Divya, Lilia Turcios, Ram Vinod Roy, John Andrew Hitron, Lei Wang, Donghern Kim, Jin Dai, Padmaja Asha, Zhuo Zhang, Xianglin Shi

Hexavalent chromium [Cr(VI)] is a well-known human carcinogen associated with an increased risk of lung cancer. However, the mechanisms underlying Cr(VI)-induced carcinogenesis remain unclear. MicroRNA-21 (miR-21) is a key regulator of oncogenic processes. Studies have shown that miR-21 exerts its oncogenic activity by targeting the tumor suppressor gene programmed cell death 4 (PDCD4). The present study examined the role of miR-21-PDCD4 signaling in Cr(VI)-induced cell transformation and tumorigenesis. Results showed that Cr(VI) induces ROS generation in human bronchial epithelial (BEAS-2B) cells. Chronic exposure to Cr(VI) is able to cause malignant transformation in BEAS-2B cells. Cr(VI) caused a significant increase of …

The Impact Of Polybrominated Diphenyl Ether (Bde-47) Administration In Mice And Its Implications In Non-Alcoholic Fatty Liver Disease, Kristen Ciampi

Senior Honors Projects

Non-alcoholic fatty liver disease (NAFLD) is a disease characterized by the accumulation of fat in liver cells that is not due to alcohol consumption. Steatosis results when more than 5-10% of the liver’s weight consists of fat. People who are overweight, or who have diabetes or high cholesterol are more likely to develop NAFLD. Over time, NAFLD can advance to cause cirrhosis, and eventually, liver cancer or failure.

Polybrominated diphenyl ethers (PBDEs, BDEs) are brominated flame- retardants, and are found in many plastics and household products such as cars, textiles, televisions, and computers. BDEs are released into the environment and …

Stinging Nettle: The Bad, The Good, The Unknown, Dennis J. Baumgardner

Journal of Patient-Centered Research and Reviews

Stinging nettle (Urtica dioica) is native to most of the United States. It has a characteristic description and distribution in the environment. Physical contact with numerous tiny needlelike hairs present on leaves and stems of this plant may result in a contact urticarial dermatitis due to chemical and mechanical irritation triggered by skin penetration of the hairs. The manifestations are self-limited in humans and may be treated by washing the skin, topical preparations and oral antihistamines. Explanation of the natural history of these encounters to the patient is helpful in reducing the sometimes significant anxiety. Preparations and extracts …

Newly Developed And Validated Eosinophilic Esophagitis Histology Scoring System And Evidence That It Outperforms Peak Eosinophil Count For Disease Diagnosis And Monitoring, Margaret H. Collins, Lisa J. Martin, Eileen Steinle Alexander, J Todd Boyd, Rachel Sheridan, Hua He, Scott Pentiuk, Philip E. Putnam, J Pablo Abonia, Vincent A. Mukkada, James P. Franciosi, Marc E. Rothenberg

Faculty Scholarship

Eosinophilic esophagitis is diagnosed by symptoms, and at least 15 intraepithelial eosinophils per high power field in an esophageal biopsy. Other pathologic features have not been emphasized. We developed a histology scoring system for esophageal biopsies that evaluates eight features: eosinophil density, basal zone hyperplasia, eosinophil abscesses, eosinophil surface layering, dilated intercellular spaces, surface epithelial alteration, dyskeratotic epithelial cells and lamina propria fibrosis. Severity (grade) and extent (stage) of abnormalities were scored using a 4 point scale (0 normal; 3 maximum change). Reliability was demonstrated by strong to moderate agreement among 3 pathologists who scored biopsies independently (p≤0.008). Several features …

“The Most Poisonous Of All Diseases Of Mind Or Body”: Colorphobia And The Politics Of Reform, April J. Gemeinhardt

Graduate Student Theses, Dissertations, & Professional Papers

Focusing on the mid-1830s through 1865, this thesis explores colorphobia—the irrational fear and hatred of black people otherwise known as racial prejudice—as a reform tactic adopted by abolitionists. It argues that colorphobia played a pivotal role in the radical abolitionist reform agenda for promoting anti-slavery, immediate emancipation, equal rights, and black advancement. By framing racial prejudice as a disease, abolitionists believed connotations, stigmas, and fears of illness would elicit more attention to the rapidly increasing racial prejudice in the free North and persuade prejudiced white Americans into changing their ways. Abolitionists used parallels to cholera, choleraphobia (fear of cholera), and …

Antioncogenic And Oncogenic Properties Of Nrf2 In Arsenic-Induced Carcinogenesis, Young-Ok Son, Poyil Pratheeshkumar, Ram Vinod Roy, Andrew Hitron, Lei Wang, Sasidharan Padmaja Divya, Mei Xu, Jia Luo, Gang Chen, Zhuo Zhang, Xianglin Shi

Center for Research on Environmental Disease Faculty Publications

Arsenic (As³⁺) is a carcinogen with considerable environmental and occupational relevancy. The present study shows that As³⁺-transformed human lung bronchial epithelial BEAS-2B cells (AsT cells) exhibit the property of apoptosis resistance. The level of basal reactive oxygen species (ROS) is very low in AsT cells in correlation with elevated expressions of both antioxidant enzymes and antiapoptotic proteins. Nuclear factor erythroid 2-related factor (Nrf2) and p62 are constitutively expressed. These two proteins up-regulate antioxidant enzymes and antiapoptotic proteins. The knockdown of Nrf2 or p62 by small interfering RNA (siRNA) enhanced both ROS levels and As³⁺-induced …

Parenchymal lung inflammation and airway and alveolar epithelial cell apoptosis are associated with cigarette smoke exposure (CSE), which contributes to chronic obstructive pulmonary disease (COPD). Epidemiological studies indicate that people exposed to chronic cigarette smoke with or without COPD are more susceptible to influenza A virus (IAV) infection. We found increased p53, PAI-1 and apoptosis in AECs, with accumulation of macrophages and neutrophils in the lungs of patients with COPD. In Wild-type (WT) mice with passive CSE (PCSE), p53 and PAI-1 expression and apoptosis were increased in AECs as was lung inflammation, while those lacking p53 or PAI-1 resisted AEC …

Evaluation Of Bde-47 And -99 Lipid Modulating Effects In Hepg2 Human Carcinoma Cells, Eileen A. Holovac

Senior Honors Projects

Non-alcoholic fatty liver disease (NAFLD) is becoming a significantly more common problem in today’s society, affecting up to 25% of people in the United States as reported by the American Liver Foundation. According to the American Association of the Study of Liver Diseases, NAFLD is the buildup of fat in the liver that is not caused by secondary factors such as alcohol consumption, hereditary disorders, or the use of steatogenic medication such as amioderone. A liver is considered fatty when 5-10% of the liver’s weight is fat. The progression of NAFLD can lead to cirrhosis, liver cancer, or liver failure. …
