Living A Long Life Is A Multi-Step Process, Alexander H. K. Montoye, Scott A. Conger

Kinesiology Faculty Publications and Presentations

There is a strong link between physical activity and health. Historically, large-scale epidemiological studies have used self-report surveys to capture physical activity measures (eg, type and intensity). In the past 20–30 years, large cohort studies have increasingly adopted devices, such as pedometers, accelerometers, and consumer-marketed activity trackers, to measure physical activity. Device-based physical activity measures alleviate some limitations of self-reporting by increasing measurement objectivity and accuracy. Additionally, device-based measures often show stronger associations with health outcomes than do self-reported measures, showcasing their value in understanding how physical activity affects health. Unlike self-report, device-based measures can capture steps, which are easily …

The Counterbalancing Effects Of Energy Expenditure On Body Weight Regulation: Orexigenic Versus Energy-Consuming Mechanisms, Paolo Piaggi, Alessio Basolo, Corby K. Martin, Leanne M. Redman, Susanne B. Votruba, Jonathan Krakoff

Clinical Research Faculty Publications

Objective: Weight change is a dynamic function of whole-body energy balance resulting from the interplay between energy intake and energy expenditure (EE). Recent reports have provided evidence for the existence of a causal effect of EE on energy intake, suggesting that increased EE may drive overeating, thereby promoting future weight gain. This study investigated the relationships between ad libitum energy intake and 24-hour EE (24-h EE) in sedentary conditions versus long-term, free-living weight change using a mediation analysis framework. Methods: Native American individuals (n = 61, body fat by dual-energy x-ray absorptiometry: 39.7% [SD 9.5%]) were admitted to the clinical …

Fit To Be Good: Physical Fitness Is Negatively Associated With Deviance, Kenneth Tai, Yuchuan Liu, Marko Pitesa, Sandy Lim, Yew Kwan Tong, Richards Arvey

Research Collection Lee Kong Chian School Of Business

While modern organizations generate economic value, they also produce negative externalities in terms of human physical fitness, such that workers globally are becoming physically unfit. In the current research, we focus on a significant but overlooked indirect cost that lack of physical fitness entails—deviance. In contrast to early (and methodologically limited) research in criminology, which suggests that physically fit people are more likely to behave in a deviant manner, we draw on self-control theory to suggest the opposite: that physically fit people are less likely to engage in deviance. In Study 1, concurrent as well as time-lagged analyses of a …

O’Doherty, Bernadette O. Fernandez, Edward T. Gilbert-Kawai, Kay Mitchell, Helen Moyses, Alexandra Cobb, Paula Meale, Helmut Pöhnl, Monty G. Mythen, Michael P.W. Grocott, Denny Z.H. Levett, Daniel S. Martin, Martin Feelisch

Peninsula Medical School

IntroductionNitrate supplementation in the form of beetroot juice (BRJ) ingestion has been shown to improve exercise tolerance during acute hypoxia, but its effect on exercise physiology remains unstudied during sustained terrestrial high altitude exposure. We hypothesized that performing exercise at high altitude would lower circulating nitrate and nitrite levels and that BRJ ingestion would reverse this phenomenon while concomitantly improving key determinants of aerobic exercise performance.MethodsTwenty seven healthy volunteers (21 male) underwent a series of exercise tests at sea level (SL, London, 75 m) and again after 5–8 days at high altitude (HA, Capanna Regina Margherita or “Margherita Hut,” 4,559 …

Crosswalking Wet Bulb Globe Temperature And Heat Index, Paul Irvin

USF Tampa Graduate Theses and Dissertations

Wet bulb globe temperature (WBGT) is a common metric to represent the environmental conditions in the assessment of heat stress. Because WBGT requires some technical expertise and sufficiently accurate equipment, there is interest in using heat index (HI) as a substitute index for the environment. Because the underlying science for understanding heat stress exposures does not exist for HI, it is necessary to crosswalk between HI and a data-driven exposure method. Expanding upon previous research, the focus of this study is the exploration of the interrelationships between WBGT and HI. The simulated weather data of Morris et. al. (2019) served …

Caloric Restriction In Humans Reveals Immunometabolic Regulators Of Health Span, O. Spadaro, Y. Youm, I. Shchukina, S. Ryu, S. Sidorov, A. Ravussin, K. Nguyen, E. Aladyeva, A. N. Predeus, S. R. Smith, E. Ravussin, C. Galban, M. N. Artyomov, V. D. Dixit

Clinical Research Faculty Publications

The extension of life span driven by 40% caloric restriction (CR) in rodents causes trade-offs in growth, reproduction, and immune defense that make it difficult to identify therapeutically relevant CR-mimetic targets. We report that about 14% CR for 2 years in healthy humans improved thymopoiesis and was correlated with mobilization of intrathymic ectopic lipid. CR-induced transcriptional reprogramming in adipose tissue implicated pathways regulating mitochondrial bioenergetics, anti-inflammatory responses, and longevity. Expression of the gene Pla2g7 encoding platelet activating factor acetyl hydrolase (PLA2G7) is inhibited in humans undergoing CR. Deletion of Pla2g7 in mice showed decreased thymic lipoatrophy, protection against age-related inflammation, …

Florence Nightingale, The Colossus: Was She A Feminist?, Susan Hogan

Journal of International Women's Studies

Nightingale displayed a particular brand of feminism that reflected the circumstances of her era. The question of women’s involvement in healthcare is addressed through an analysis of Nightingale’s most famous work, Notes on Nursing. What it is, and what it is not (1859/60). Then other key works are scrutinised with reference to ideas about female involvement in healthcare and how she addresses the position of women in general terms. Nightingale’s works, Notes on Hospitals (1859); Suggestions for Thought to the Searchers after Truth among the Artisans of England (1860); Introductory Notes on Lying-In Institutions (1871) are focussed upon illustrating her …

A Study Of Relationships Among Three Assessment Methods For Nurse Anesthetists, Nicholas W. Gabriel

Dissertations

The current measures of competency for nurse anesthetists for recertification are continuing education units for each biennial recertification cycle, and records of current practice and state licensure. Recently, the National Board of Certification and Recertification of Nurse Anesthetists (NBCRNA) adopted new standards that include a written examination every 8 years, an increase of 40 continuing education units per year, and completion of four core competency modules each four-year recertification cycle. However, little is known about the validity of these competency measures.

The purpose of this study was to determine relationships between written examination scores, self-assessment scores, and performance scores in …

Objective: Intra-tumoral expression of the serine hydrolase carboxylesterase 2 (CES2) contributes to the activation of the pro-drug irinotecan in pancreatic ductal adenocarcinoma (PDAC). Given other potential roles of CES2, we assessed its regulation, downstream effects, and contribution to tumor development in PDAC.

Methods: Association between the mRNA expression of CES2 in pancreatic tumors and overall survival was assessed using The Cancer Genome Atlas. Cell viability, clonogenic, and anchorage-independent growth assays as well as an orthotopic mouse model of PDAC were used to evaluate the biological relevance of CES2 in pancreatic cancer. CES2-driven metabolic changes were determined by untargeted and targeted …

Effects Of Placebo Administration On Immune Mechanisms And Relationships With Central Endogenous Opioid Neurotransmission, Alan Prossin, Alisa Koch, Phillip Campbell, Geoffroy Laumet, Christian S Stohler, Robert Dantzer, Jon-Kar Zubieta

Faculty, Staff and Student Publications

Behavioral conditioning and expectation can have profound impact on animal and human physiology. Placebo, administered under positive expectation in clinical trials, can have potent effects on disease pathology, obscuring active medications. Emerging evidence suggests placebo-responsive neurotransmitter systems (e.g., endogenous opioid) regulate immune function by manipulating inflammatory proteins including IL-18, a potent pro-inflammatory, nociceptive cytokine implicated in pathophysiology of various diseases. Validation that neuroimmune interactions involving brain μ-opioid receptor (MOR) activity and plasma IL-18 underlie placebo analgesic expectation could have widespread clinical applications. Unfortunately, current lack of mechanistic clarity obfuscates clinical translation. To elucidate neuroimmune interactions underlying placebo analgesia, we exposed …
