Faculty Publications

Injuries and subclinical effects from exposure to blasts are of significant concern in military operational settings, including tactical training, and are associated with self-reported concussion-like symptomology and physiological changes such as increased intestinal permeability (IP), which was investigated in this study. Time-series gene expression and IP biomarker data were generated from “breachers” exposed to controlled, low-level explosive blast during training. Samples from 30 male participants at pre-, post-, and follow-up blast exposure the next day were assayed via RNA-seq and ELISA. A battery of symptom data was also collected at each of these time points that acutely showed elevated symptom …

Risk Assessment Of Blood-Borne Pathogen Exposure For Emergency Responders, Jill A. Ireland

USF Tampa Graduate Theses and Dissertations

Emergency responders face a significant risk of exposure to blood-borne pathogens (BBPs), such as HIV and hepatitis, due to the nature of their work environment. This study investigates this issue utilizing a dual approach of data analysis and online surveys to assess exposure rates, risk perceptions, factors that contribute to risk and prevention practices. In addressing issues ranging from personal protective equipment (PPE) usage to levels of concern surrounding blood and bodily fluid contact, the findings underscore the need for tailored safety measures, comprehensive education, and improved prevention strategies.

The examination of 346 worker's compensation exposure claims highlighted a significant …

Interrelationships Among Local Values Of Wet Bulb Globe Temperature, Heat Index, And Adjusted Temperature, Andrea Giraldo

USF Tampa Graduate Theses and Dissertations

Occupational heat stress significantly affects outdoor workers who face challenges due to increased heat exposure. Because of the prevalence of heat illness, it is important to measure heat stress for outdoor workers. Monitoring occupational heat stress most often relies on the Wet Bulb Globe Temperature (WBGT) measure. Heat Index (HI) is a widely used measure to account for air temperature and humidity. Adjusted Temperature (Tadj) considers air temperature, humidity and estimates radiant heat. There is interest in predicting WBGT from HI and HI from WBGT. This study builds on previous USF research by Bernard and Iheanacho and Irvin to evaluate …

Ateneo School of Medicine and Public Health Publications

Background

Given the lack of previous studies on adverse events (AEs) in the area of occupational healthcare in Spain, it is very important to begin to understand this phenomenon in order to act on it. The objective was to accurately quantify AE occurring in occupational healthcare in MC Mutual during May 2021.

Methods

We conducted a review of a representative random sample of 250 clinical records to identify AEs through an active search audit, focused on the frequency, type, severity, and preventability of these events, categorized using standardized scales.

An Investigation Of Torso Muscle Fatigue And Its Relation To Discomfort During Vertical Vibration Exposure, Nathan H. Hodges

Theses and Dissertations

Military and civilian helicopter pilots often experience back pain attributed to vibration exposure during flight and sustained poor posture, known as the "helicopter hunch." This study investigated torso muscle activation using surface electromyography (EMG) to assess the relationship between discomfort and muscle fatigue. Eight subjects were exposed to different vibration frequencies over two-hour periods, with EMG data collected every five minutes. Significant differences in muscle activation were observed before and after vibration exposure, suggesting increased muscle activation during vibration compared to prolonged seating alone. Discomfort surveys indicated higher discomfort during vibration.

The Great Resignation: Narratives Of Mid-Career Teacher Burnout And Attrition, Nicole Burton

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

The COVID-19 pandemic has increased the issues of teacher attrition. According to the U.S. Bureau of Labor and Statistics, from January to November 2021, there was a 40% increase in the quit levels of teachers within the state and local education agencies (John, 2022). While prior research has examined early-career teachers leaving the profession, mid-career teachers have largely been left out of the conversation. This narrative inquiry investigates the reasons that mid-career teachers are leaving the profession. Semi-structured interviews were conducted with four mid-career teachers hailing from the Midwest region. Interviews focused on understanding how teachers have experienced stress and …

Personal Dosimeter Testing For High Altitude Air Crew, Seth D. Bacon

Theses and Dissertations

In 2014 the Thermo Scientific N2 electronic personal dosimeter became the aircrews’ sole means to record ionizing radiation dose. The production of this dosimeter was discontinued in July of 2021, motivating the Air Force to seek a flight-certifiable replacement. The Thermo Scientific Trudose NG, Mirion DMC 3000, and Fuji NRF-51 electronic personal dosimeters, as well as the Landauer InLight optically stimulated luminescent dosimeter, were subjected to mixed gamma and fast neutron fields simulating a high-altitude flight environment. Dosimeters are evaluated on their consistency and accuracy in reporting dose and compared to the current N2 dosimeter’s reported dose.

Radiological Decontamination Methodologies On Litter-Bound Patients In Arctic Environments, And The Associated Airborne Risks Posed To First Responders, Juan S. Alb

Theses and Dissertations

This study was conducted to determine if air-based decontamination (decon) methods would be effective at both treating patients exposed to dry, radiological contamination as well as reducing its re-aerosolization during the disrobing process, such that these methods could be applied on litter-bound patients in extreme cold environments. A litter-bound, full-size mannequin dressed in a set of standard military issue extreme cold weather jacket and pants coated in 27 g (1 Tbs) of Copper Oxide (density 6.315 g/cm³ ) was given one of three treatments for dry aerosol decon. The three cleaning treatments included high-efficiency particulate air (HEPA) vacuum, a …

Retrospective Cohort Study Of Pure Tone Audiometry Hearing Changes From Ototoxic Metalsand Solvents, Continuous Noise, And Impulse Noise Exposures At Hill Air Force Base From 2005 To 2019, Zachary I. Johnson

Theses and Dissertations

This retrospective cohort epidemiological study investigated the relative risks of hearing loss associated with ototoxicants in combination with noise exposure. Utilizing Department of Defense (DoD) industrial hygiene and hearing conservation data, this research expanded on a 2020 thesis conducted on Tinker Air Force Base (AFB), applying a similar methodology to Hill AFB, adding 893 evaluated individuals. Grouped into twelve exposure combinations with a minimum of three years of exposure duration, the study assessed various hearing loss indicators, including DoD Standard Threshold Shift (STS) and NIOSH STS. Ototoxic substances consistently elevated relative risk (RR) compared to noise-only exposure groups, but none …

Daily Income Targets And Passenger Pressure On Safety Risky Riding Behavior Among Online Motorcycle Taxi Riders In Jakarta, Indonesia, Zulkifli Djunaidi, Agra Mohamad Khaliwa, Azka Hafia, Nadya Putri

Kesmas

Online motorcycle taxi riders, a vulnerable group on the road, are more susceptible to serious injury than non-motorcycle riders. This study analyzed a correlation between daily income targets, passenger pressure, risk perception, safety attitudes, and risky riding behavior. This cross-sectional study used a semi-quantitative approach by collecting online-based questionnaires from 500 online motorcycle taxi riders in Jakarta, and 50 of them were obtained through offline interviews. The findings revealed a significant relationship between daily income targets, passenger pressure, risk perception (danger level, stochastic evaluation, and safety priority), safety attitudes (pragmatic attitude to rule violations and dissatisfaction with traffic rules), and …

Whitening Efficacy Of Activated Charcoal-Based Dentifrices Related To The Mode Of Action And Adverse Effects On The Tooth Surface, Douglas Silva

Annual Research Symposium

To evaluate if tooth color alteration of activated charcoal-based dentifrices may be attributed to the dye adsorption potential of charcoal (chemical action - C - slurry only) or to the association of dye adsorption with abrasion (chemo-mechanical action - CM- slurry/toothbrushing). Potential adverse effects in surface roughness, gloss, and wear were also assessed.
