The effects of a long-term combat deployment on a soldier's physical fitness are not well understood. In active duty soldiers, combat deployment reduced physical fitness compared to pre-deployment status, but no similar research has been performed on Army National Guard soldiers. This study is the first to identify physical fitness changes in Arizona National Guard (AZNG) soldiers following deployment to a combat zone and to assess the relationships between physical fitness and non-combat injuries and illness (NCII). Sixty soldiers from the Arizona National Guard (AZNG) completed a battery of physical fitness tests prior to deployment and within 1-7 days of returning from a 12-month deployment to Iraq. Pre and post-deployment measures assessed body composition (Bod Pod), muscular strength (1RM bench press, back-squat), muscular endurance (push-up, sit-up), power (Wingate cycle test), cardiorespiratory fitness (treadmill run to VO2 peak), and flexibility (sit-and-reach, trunk extension, shoulder elevation). Post deployment, medical records were reviewed by a blinded researcher and inventoried for NCII that occurred during deployment. Data were analyzed for changes between pre and post-deployment physical fitness. Relationships between fitness and utilization of medical resources for NCII were then determined. Significant declines were noted in mean cardiorespiratory fitness (-10.8%) and trunk flexibility (-6.7%). Significant improvements were seen in mean level of fat mass (-11.1%), relative strength (bench press, 10.2%, back-squat 14.2%) and muscular endurance (push-up 16.4%, sit-up 11.0%). Significant (p < 0.05) negative correlations were detected between percentage change in fat mass and gastrointestinal visits (r = -0.37); sit-and-reach and lower extremity visits (r= -0.33); shoulder elevation and upper extremity visits (r= -0.36); and cardiorespiratory fitness and back visits (r= -0.31); as well as behavioral health visits (r= -0.28). Cardiorespiratory fitness changes were grouped into tertiles. Those who lost the greatest fitness had significantly greater number of NCII visits (8.0 v 3.1 v 2.6, p = .03). These data indicate a relationship between the decline in cardiorespiratory fitness and an overall increase in utilization of medical resources. The results may provide incentive to military leaders to ensure that soldiers maintain their cardiorespiratory fitness throughout the extent of their deployment.

The nineteenth-century invention of smallpox vaccination in Great Britain has been well studied for its significance in the history of medicine as well as the ways in which it exposes Victorian anxieties regarding British nationalism, rural and urban class struggles, the behaviors of women, and animal contamination. Yet inoculation against smallpox by variolation, vaccination’s predecessor and a well-established Chinese medical technique that was spread from east to west to Great Britain, remains largely understudied in modern scholarly literature. In the early 1700s, Lady Mary Wortley Montagu, credited with bringing smallpox variolation to Great Britain, wrote first about the practice in the Turkish city of Adrianople and describes variolation as a “useful invention,” yet laments that, unlike the Turkish women who variolate only those in their “small neighborhoods,” British doctors would be able to “destroy this [disease] swiftly” worldwide should they adopt variolation. Examined through the lens of Edward Said’s Orientalism, techno-Orientalism, and medical Orientalism and contextualized by a comparison to British attitudes toward nineteenth century vaccination, eighteenth century smallpox variolation’s introduction to Britain from the non-British “Orient” represents an instance of reversed Orientalism, in which a technologically deficient British “Occident” must “Orientalize” itself to import the superior medical technology of variolation into Britain. In a scramble to retain technological superiority over the Chinese Orient, Britain manufactures a sense of total difference between an imagined British version of variolation and a real, non-British version of variolation. This imagination of total difference is maintained through characterizations of the non-British variolation as ancient, unsafe, and practiced by illegitimate practitioners, while the imagined British variolation is characterized as safe, heroic, and practiced by legitimate British medical doctors. The Occident’s instance of medical technological inferiority brought about by the importation of variolation from the Orient, which I propose represents an eighteenth-century instance of what I call medical techno-Orientalism, represents an expression of British anxiety over a medical technologically superior Orient—anxieties which express themselves as retaliatory attacks on the Orient and variolation as it is practiced in the Orient—and as an expression of British desire to maintain medical technological superiority over the Orient.

The social determinants of health (SDOH) represent factors that impact the health and effectiveness/compliance of a treatment plan for a patient. The SDOH include such factors as economic stability, education, home and community context, access to healthcare, neighborhood and built environment, and personal behavior. The purpose of this study is to determine the extent of collection and integration of SDOH into clinical practice, and the usefulness of this information in medical decision making. Following a thorough literature review, an online survey was deployed to physicians and administrators around the country, with the aim of answering the following questions: 1) Do provider practices collect information on a patient's social determinants of health? 2) If yes, how is that information being used, if at all? 3) If not, what is preventing them from doing so? 4) Do the answers to questions 1-3 differ based on the type of payment model (Fee-for-Service or Capitation) to which the practice is subject? The results of the study suggest that fee-for-service payment environments present less incentive to use a patient's SDOH in medical decision making.

In the search for chemical biosensors designed for patient-based physiological applications, non-invasive diagnostic approaches continue to have value. The work described in this thesis builds upon previous breath analysis studies. In particular, it seeks to assess the adsorptive mechanisms active in both acetone and ethanol biosensors designed for breath analysis. The thermoelectric biosensors under investigation were constructed using a thermopile for transduction and four different materials for biorecognition. The analytes, acetone and ethanol, were evaluated under dry-air and humidified-air conditions. The biosensor response to acetone concentration was found to be both repeatable and linear, while the sensor response to ethanol presence was also found to be repeatable. The different biorecognition materials produced discernible thermoelectric responses that were characteristic for each analyte. The sensor output data is presented in this report. Additionally, the results were evaluated against a mathematical model for further analysis. Ultimately, a thermoelectric biosensor based upon adsorption chemistry was developed and characterized. Additional work is needed to characterize the physicochemical action mechanism.

Cardiovascular disease is one of the most deadly outcomes of end stage renal disease. Bioelectrical impedance is a intriguing, yet unproven method of measuring fluid buildup in the heart, and is marketed as a early diagnostic tool for onset of cardiovascular disease. In this study, selenium supplements were given to a cohort of dialysis patients in the Phoenix metro area and their fluid tolerance was measured with thoracic biolectrical impedance. BNP was used as a correlate to see if bioelectrical impedance was correlated with heart disease. The study found no correlation between BNP and bioelectrical impedance and thus was not an accurate diagnostic tool in a medical setting.

Medical practice surrounding tuberculosis (TB) treatment in two nineteenth-century Scottish charitable hospitals reveals that in developing empirically-positioned constructs of this and related diseases, medical practitioners drew upon social assumptions about women and the working classes, thus reinforcing rather than shedding cultural notions of who becomes ill and why. TB is a social disease, its distribution determined by relationships among human groups; primary among these is the patient-practitioner relationship, owing to the social role of medical treatment in restoring the ill to both health and society. To clarify the influence of cultural context upon the evolution of medical constructs of TB, I examined Glasgow Royal Infirmary (GRI) and Royal Infirmary of Edinburgh (RIE) ward journals, admissions registers, and institution management records from 1794 through 1905. Medical practice at the turn of the nineteenth century was dominated by observation and questioning of the patient, concordant with conceptions of physicians' labor as mental rather than physical. This changed with the introduction of the stethoscope in the 1820s, which together with the dissection of the poor allowed by the 1832 Anatomy Act ushered in disease concepts emphasizing pathological anatomy. Relationships between patient and practitioner also altered at this time, exhibiting distrust and medical dominance. The mid-Victorian era was notable for clinicians' increasing interest in immorality's contributions to ill health, absent in earlier practice and linked to conceptions of women and the working classes as inherently pathological. In 1882, discovery of the tubercle bacillus challenged existing nutritional, hereditary, and environmental explanations for TB. Although practitioners utilized bacteriological methods, this discovery did not revolutionize diagnosis or treatment. Rather, these older models were incorporated with perceived behavioral, environmental, and biological degradation of the working classes, rendering marginalized groups "soil" prepared for the "seeds" of disease -- at risk, but also to blame. This framework, in which marginalized groups contribute to their increased risk for disease through refusal to accord with hegemonically-established "healthy" behavior, persists. As a result, meaningful change in TB rates will need to address these longstanding contributions of social inequality to Western medical treatment.

Statistical process control (SPC) and predictive analytics have been used in industrial manufacturing and design, but up until now have not been applied to threshold data of vital sign monitoring in remote care settings. In this study of 20 elders with COPD and/or CHF, extended months of peak flow monitoring (FEV1) using telemedicine are examined to determine when an earlier or later clinical intervention may have been advised. This study demonstrated that SPC may bring less than a 2.0% increase in clinician workload while providing more robust statistically-derived thresholds than clinician-derived thresholds. Using a random K-fold model, FEV1 output was predictably validated to .80 Generalized R-square, demonstrating the adequate learning of a threshold classifier. Disease severity also impacted the model. Forecasting future FEV1 data points is possible with a complex ARIMA (45, 0, 49), but variation and sources of error require tight control. Validation was above average and encouraging for clinician acceptance. These statistical algorithms provide for the patient's own data to drive reduction in variability and, potentially increase clinician efficiency, improve patient outcome, and cost burden to the health care ecosystem.

Purpose: The purpose of this study was to examine the acute effects of two novel intermittent exercise prescriptions on glucose regulation and ambulatory blood pressure. Methods: Ten subjects (5 men and 5 women, ages 31.5 ± 5.42 yr, height 170.38 ± 9.69 cm and weight 88.59 ± 18.91 kg) participated in this four-treatment crossover trial. All subjects participated in four trials, each taking place over three days. On the evening of the first day, subjects were fitted with a continuous glucose monitor (CGM). On the second day, subjects were fitted with an ambulatory blood pressure monitor (ABP) and underwent one of the following four conditions in a randomized order: 1) 30-min: 30 minutes of continuous exercise at 60 - 70% VO2peak; 2) Mod 2-min: twenty-one 2-min bouts of walking at 3 mph performed once every 20 minutes; 3) HI 2-min: eight 2-min bouts of walking at maximal incline performed once every hour; 4) Control: a no exercise control condition. On the morning of the third day, the CGM and ABP devices were removed. All meals were standardized during the study visits. Linear mixed models were used to compare mean differences in glucose and blood pressure regulation between the four trials. Results: Glucose concentrations were significantly lower following the 30-min (91.1 ± 14.9 mg/dl), Mod 2-min (93.7 ± 19.8 mg/dl) and HI 2-min (96.1 ± 16.4 mg/dl) trials as compared to the Control (101.1 ± 20 mg/dl) (P < 0.001 for all three comparisons). The 30-min trial was superior to the Mod 2-min, which was superior to the HI 2-min trial in lowering blood glucose levels (P < 0.001 and P = 0.003 respectively). Only the 30-min trial was effective in lowering systolic ABP (124 ± 12 mmHg) as compared to the Control trial (127 ± 14 mmHg; P < 0.001) for up to 11 hours post exercise. Conclusion: Performing frequent short (i.e., 2 minutes) bouts of moderate or high intensity exercise may be a viable alternative to traditional continuous exercise in improving glucose regulation. However, 2-min bouts of exercise are not effective in reducing ambulatory blood pressure in healthy adults.

This dissertation focuses on the connections between childbirth and spirituality in fourteenth- and early fifteenth-century England. It argues that scholastic interest in conception and procreation led to a proliferation of texts mentioning obstetrics and gynecology, and that this attention to women's medicine and birth spread from the universities to the laity. This dissertation contends that there is interdependence between spiritual and physical health in late medieval English religious culture, correlated with and perhaps caused by an increasing fascination with materialism and women's bodies in religious practices and rhetoric. The first chapter provides an analysis of birth in medical and pastoral texts. Pastoral works were heavily influenced by the ecclesiastical emphasis on baptism, as well as by scholastic medicine's simultaneous disdain for and reluctant integration of folk medicine. The second chapter examines birth descriptions in narratives of saints' miracles and collections of exempla; these representations of childbirth were used in religious rhetoric to teach, motivate, and dissuade audiences. The third chapter turns to the cycle play representations of the nativity as depicting the mysteries of human generation and divine incarnation for public consumption. The fourth chapter analyzes the abstract uses of childbirth in visionary and other religious texts, especially in descriptions of spiritual rebirth and the development of vice and virtue in individuals or institutions. By identifying their roles as analogous with the roles of midwives, visionaries authorized themselves as spiritual caretakers, vital for communal health and necessary for collective spiritual growth. These chapters outline a trajectory of increasing male access to the birthing chamber through textual descriptions and prescriptions about birth and midwifery. At the same time, religious texts acknowledged, sought to regulate, and sometimes even utilized the potential authority of mothers and midwives as physical and spiritual caretakers.

Background: The shortage of available dietetic internship (DI) positions for qualified applicants threatens the future of dietetics. Only about half of all applicants will obtain a slot. Additional internship positions are needed and can be offered only if more practitioners become preceptors. Objective: To examine the perceptions associated with the role of DI preceptor among nutrition and dietetic practitioners and identify barriers and motivators to becoming a DI preceptor in Arizona. Design: An online survey adapted from previous published instruments was administered between July and September 2011 to dietetic and nutrition professionals eligible to precept dietetic interns. Participants: RD, DTR, and school food service professionals on file with Arizona registries were invited to participate in the survey. A total of 675 subjects participated in the study. Statistical analyses performed: Chi-square analysis was used to assess differences between preceptors and non-preceptors for categorical variables. Independent t-tests were used to analyze differences between groups for continuous variables. Results: Respondents included 314 current or former preceptors and 361 non-preceptors with no significant differences in gender, age, or race between groups. Preceptors typically perceived the preceptor role more favorably than non-preceptors. Non-preceptors reported fewer benefits and more disadvantages to being a preceptor. Only 18% of non-preceptors knew how to become a mentor. Conclusions: Motivators for practitioners to become preceptors and continue in the role include personal benefits, dedication to the role and profession, and contributions to the workplace by interns. Barriers to mentoring interns include lack of compensation, increased workload, lack of support, lack of training, lack of resources, intern liability, and lack of knowledge of how to become a preceptor. Results of the study can be used to target barriers and emphasize benefits associated with the preceptor role to encourage participation in the preceptor process to make more internship positions available.
