Exploring Prenatal Physical Activity at the “Postgenomic Turn”: A Transdisciplinary Journey

Abstract

Within the life sciences, there has been a move away from genetic determinism toward an awareness of how the environment (from cellular to social) can impact gene expression and health outcomes. Significantly, exercise scientists are looking to this “postgenomic turn” to explore how prenatal physical activity and leisure might affect the fetal metabolic environment by altering offspring gene expression and preventing future obesity. In this article, we draw upon insights from feminist new materialist scholars to explore how and if the entanglement of the social and material promised by the postgenomic turn is realized in prenatal exercise interventions. After outlining how this is not the case, we reflect upon our attempt to promote a transdisciplinary dialogue that facilitates a social justice ethos and nonreductionist version of maternal-fetal health and physical culture. Our transdisciplinary journey contributes to the feminist physical cultural studies agenda of equity development in the realm of exercise and leisure.     

Training,tracking, and traversing: digital materiality and the production of bodies and/in space in runners’ fitness tracking practices

ABSTRACT

The impact of the Quantified Self (QS) movement, or the digital quantification of the body for the purposes of self-betterment, on leisure has been well-established within the literature. Drawing on the experiences of ten women who self-track while running, this project extends the literature on running and place, and lived experiences of the QS, by considering the role of fitness tracking on embodiment and emplacement. First, I trouble the notion that running data is an objective replication of a runner’s activities, illustrating instead that fitness tracking is an accomplishment of human and non-human agencies and that this accomplishment does not always go according to the runner’s plan. Second, I complicate the idea that personal data collection is a disembodying act that turns visceral sensations into impersonal numbers. Instead, I argue that running data collection is often intertwined with visceral and experiential aspects of running, thus maintaining a connection between the body and the data that is collected on that body. In so doing, I contribute to digital leisure studies efforts to characterise the lived experiences of self-tracking, pointing in particular to the role of non-humans and place in those lived experiences.     

Testing a susceptibility threshold for risk promotion messages in the shark diving context

Abstract

This paper presents the results of two experiments designed to test a susceptibility threshold in the shark cage diving context, positing that persons who are high relative to low sensation-seekers are more likely to approach risks that are portrayed as scary and moderately probable. The results of study one provide evidence for the susceptibility threshold showing high sensation-seekers having greater behavioral intent to engage in risk behaviors when a message portrays a scary but only moderately probable risk. The second experiment finds high susceptibility messages result in more negative attitudes and behavioral intentions. Implications for risk message design and theory are addressed.     

Modeling operational quality metrics and costs of long-acting antibiotics for acute bacterial skin and skin structure infection treatment in the emergency department

Aims: To model implementation of a new treatment pathway leveraging long-acting antibiotics (LAs) for treatment of acute bacterial skin and skin structure infections (ABSSSIs) in a hospital emergency department (ED) with an observation unit, and to quantify health resource utilization and economic outcomes versus standard care (intravenous vancomycin).

Materials and methods: Discrete-event simulation was used to model implementation of the LA treatment pathway in the ED versus standard care from the US Medicare perspective. Model inputs were derived from published sources to simulate a real-world hospital ED with an observation unit. Outcomes included key ED metrics such as patient throughput rate and length of stay (LOS) and cost (estimated through reimbursed amounts in 2017 USD).

Results: Implementation of an LA pathway in the ED improved ABSSSI patient throughput rate by 350% (+5.8 dispositions/ED and observation unit day) and reduced LOS by 68% (?7.2?h/patient). These improvements in patient outcomes are driven by the reduced infusion time required for LA antibiotics and are greater for dalbavancin than oritavancin owing to the shorter infusion duration (30?min vs. 3?h).

Limitations: External validity of the model was not assessed. The model was limited to care received in EDs; therefore, certain clinical variables outside the ED were not captured for this analysis.

Conclusions: LA pathway implementation for ABSSSI treatment in the ED supported improved efficiency, which may translate to economic value. As EDs continue to focus on improving key metrics such as throughput rate and LOS, LA pathway implementation should be considered as a potential approach for abbreviated ABSSSI treatment in the ED.
