Occupational Stress And Risk For Parkinson's Disease: A Nationwide Cohort Study, Johanna Sieurin, Ross Andel, Annika Tillander, Elise G. Valdes, Nancy L. Pederson, Karin Wirdefeldt

Aging Studies Faculty Publications

Background: Stress has been suggested as a contributing factor in the etiology of Parkinson's Disease (PD), but epidemiological evidence is sparse.

Objective: The objective of this study was to explore the association between occupational stress according to the job demands‐control model and the risk for PD.

Methods: We conducted a population‐based cohort study with 2,544,748 Swedes born 1920 to 1950 who had an occupation reported in the population and housing censuses in 1980 or, if missing, in 1970. Job demands and control were measured using a job‐exposure matrix. Incident PD cases were identified using Swedish national health registers from 1987 …

Chronic Hippocampal Abnormalities And Blunted Hpa Axis In An Animal Model Of Repeated Unpredictable Stress, Moustafa Algamal, Joseph O. Ojo, Carlyn P. Lungmus, Phillip Muza, Constance Cammarata, Margaret J. Owens, Benoit C. Mouzon, David M. Diamond, Michael Mullan, Fiona Crawford

Incidence of post-traumatic stress disorder (PTSD) ranges from 3 to 30% in individuals exposed to traumatic events, with the highest prevalence in groups exposed to combat, torture, or rape. To date, only a few FDA approved drugs are available to treat PTSD, which only offer symptomatic relief and variable efficacy. There is, therefore, an urgent need to explore new concepts regarding the biological responses causing PTSD. Animal models are an appropriate platform for conducting such studies. Herein, we examined the chronic behavioral and neurobiological effects of repeated unpredictable stress (RUS) in a mouse model. 12 weeks-old C57BL/6J male mice were …

Evaluating Effects Of Deposit Contracting On Oral Contraceptive Adherence, Sandy Au Yeung

USF Tampa Graduate Theses and Dissertations

There is a high prevalence of nonuse and imperfect use of oral contraceptives (OCs) that can result in multiple consequences, one of which is unintended pregnancy. Deposit contracting may be promising for increasing OC adherence, however, there is little research testing deposit contracting on oral contraceptive adherence. In addition, studies have concluded that young women with elevated stress symptoms are at risk of contraceptive nonuse. Purposes of this thesis were to evaluate effects of deposit contracting on OC use for women, and the relation of stress to timely pill consumption. In addition, reliability was measured between the different measurements used …

Manipulating Relative Lmx: Effects On Performance, Conflict, And Strain, Keaton A. Fletcher

USF Tampa Graduate Theses and Dissertations

Fundamental to the conceptualization of leader-membership exchange (LMX), particularly within the context of teams, is that leaders do not necessarily treat each follower equally. Studies that have examined LMX within the context of the team often fail to capture these complexities, or rely exclusively upon self-report, or survey-based data to make inferences. Therefore, it is the purpose of this study to examine the effects of experimentally manipulated relative LMX within teams on individual conflict processes, attitudes, and psychological distress, as well as team-level performance. This study examined conflict processes and outcomes within 113 virtual, project teams engaged in a decision-making …

Do Host‐Associated Gut Microbiota Mediate The Effect Of An Herbicide On Disease Risk In Frogs?, Sarah A. Knutie, Caitlin R. Gabor, Kevin D. Kohl, Jason R. Rohr

Integrative Biology Faculty and Staff Publications

1. Environmental stressors, such as pollutants, can increase disease risk in wildlife. For example, the herbicide atrazine affects host defences (e.g. resistance and tolerance) of the amphibian chytrid fungus Batrachochytrium dendrobatidis (Bd), but the mechanisms for these associations are not entirely clear. Given that pollutants can alter the gut microbiota of hosts, which in turn can affect their health and immune systems, one potential mechanism by which pollutants could increase infection risk is by influencing host‐associated microbiota.
2. Here, we test whether early‐life exposure to the estimated environmental concentration (EEC; 200 μg/L) of atrazine affects the gut bacterial composition of …

Prevention Of Post Intensive Care Syndrome-Family With Sensation Awareness Focused Training Intervention: A Randomized Controlled Trial Pilot Study, Paula L. Cairns

USF Tampa Graduate Theses and Dissertations

Post Intensive Care Syndrome-Family (PICS-F) refers to acute and chronic psychological effects of critical illness on family members of patients in intensive care units (ICU). Evidence about the increase and persistence of PICS-F warrants the need for prevention interventions. This study evaluated the feasibility of providing Sensation Awareness Focused Training (SĀF-T) during the ICU stay for spouses of mechanically ventilated patients. Methods: A randomized controlled trial of SĀF-T versus a control group was conducted (n=10) to assess safety, acceptability, feasibility, and effect size of the intervention on PICS-F symptoms. Symptoms assessed as outcome measures included stress, anxiety, depression, posttraumatic stress …
