Rim-To-Rim Wearables At The Canyon For Health (R2r Watch): Physiological, Cognitive, And Biological Markers Of Performance Decline In An Extreme Environment, Kristin Divis, Robert Abbott, Cathy Branda, Glory Emmanuel-Aviña, Jon Femling, J. Gabriel Huerta, Lucie Jelinková, J. Kyle Jennings, Emily A. Pearce, Daniel Ries, Danielle Sanchez, Austin Silva

Journal of Human Performance in Extreme Environments

Success in extreme environments comes with a cost of subtle performance decrements that if not mitigated properly can lead to lifethreatening consequences. Identification and prediction of performance decline could alleviate deleterious consequences and enhance success in challenging and high-risk operations. The Rim-to-Rim Wearables at the Canyon for Health (R2R WATCH) project was designed to examine the cognitive, physiological, and biological markers of performance decline in the extreme environment of the Grand Canyon Rim-to-Rim (R2R) hike. The study utilized commercial off-the-shelf cognitive and physiological monitoring techniques, along with subjective self-assessments and hematologic measurements to determine subject performance and changes across the …

Working Out The Kinks: Creating Solutions To Assist Health Care Workers To Take Vital Signs Through Effective Cable Management, Carl R. Russell Iii, Emily J. Linder, Maya A. Godbole

Purdue Journal of Service-Learning and International Engagement

EPICS (Engineering Projects in Community Service) is a service-learning design program run through Purdue University. It strives to teach students design skills through providing solutions for individuals, communities, and organizations in the surrounding area while mirroring engineering industry standards. BME (Bio-medical Engineering) is a team within EPICS that strives to serve community partners through biomedical applications. Members of a health care team often spend valuable time organizing cables associated with machines used to take patients’ vital signs. Due to time constraints and the fast-paced work environment, these cables may be mismanaged and damaged. The BME team is working on a …

Influence Of Core Temperature On Psychomotor Performance During Cold Weather Military Training, Douglas Jones, Rebecca Weller, Stephen Eggan, Nicholas Roberts, Weimin Zheng, Jay Heaney, Timothy Dunn

Journal of Human Performance in Extreme Environments

Purpose: Cold environments may deteriorate psychomotor performance due to slowing of neuronal signals, distractions caused by pain and discomfort, and a loss of manual dexterity. The extent to which core temperature (T_c) influences psychomotor performance in the cold has not been established. Therefore, psychomotor performance and T_c were assessed during a cold weather military training exercise to evaluate this relationship.

Methods: Thirty-six military personnel (age: 26 ± 4 yr, ht: 175 ± 8 cm, wt: 79.1 ± 11.1 kg) participating in cold weather training volunteered for this study. Participants completed a 10-min immersion in cold (1°C) water, …

Developing Drug Therapies: Cognitive Damage In Mice Following Brain Radiation, Rachel Yuska

The Journal of Purdue Undergraduate Research

Pediatric brain cancer patients are at a high risk for radiation-induced cognitive impairment due to white matter changes in the brain. Half of six-month radiotherapy survivors develop significant changes in white matter. Previous research has shown that a mouse model can be used to show similar cognitive and behavioral deficits in human patients. The purpose of this work is to evaluate the effectiveness of two drug therapies, Donepezil and 3,3-Diindolylmethane (DIM), that could be used to either protect the brain from radiation injury or cure the cognitive injury and behavioral deficits that result from whole-brain irradiation. This project consisted of …

Technical Freediving: An Emerging Breath-Hold Diving Technique, Derek Covington, Robert H. Lee, Steven Toffel, Alberto Bursian, Kirk Krack, Chris Giordano

Journal of Human Performance in Extreme Environments

Technical freediving can be defined as freediving augmented by the use of oxygen-enriched gases or oxygen before, during, or after a freedive. As a result of these techniques, breath-hold divers can visit and enjoy underwater wrecks, reefs, and other diving locations previously located at depths unreachable to apnea divers. By pre-breathing oxygen-enriched gases in conjunction with hyperventilation—which decreases the partial pressure of carbon dioxide (PCO2)—the technical freediver now has additional oxygen to facilitate aerobic respiration during the dive. In addition, pre-breathing oxygen decreases tissue nitrogen tensions, which limits inert gas loading and decreases the risk of decompression sickness (DCS). Finally, …

Physiological And Cognitive Factors Related To Human Performance During The Grand Canyon Rim-To-Rim Hike, Kristin Divis, Clifford Anderson-Bergman, Robert Abbott, Victoria Newton, Glory Emmanuel-Aviña

Journal of Human Performance in Extreme Environments

Exposure to extreme environments is both mentally and physically taxing, leading to suboptimal performance and even life-threatening emergencies. Physiological and cognitive monitoring could provide the earliest indicator of performance decline and inform appropriate therapeutic intervention, yet little research has explored the relationship between these markers in strenuous settings. The Rim-to-Rim Wearables at the Canyon for Health (R2RWATCH) study is a research project at Sandia National Laboratories funded by the Defense Threat Reduction Agency to identify which physiological and cognitive phenomena collected by non-invasive wearable devices are the most related to performance in extreme environments. In a pilot study, data were …

Effects Of Body Armor And Load Carriage On Lower Limb Joint Movement, Huiju Park, Donna Branson, Adriana Petrova, Semra Peksoz, Carla Goad, Aric J. Warren, Bert Jacobson, Panagiotis Kamenidis

Journal of Human Performance in Extreme Environments

This study investigated the impact of body armor weight and load magnitude and distribution on the lower extremities during walking. Range of motion (ROM) was assessed while seven healthy, male, right-handed, military university students walked while wearing seven different garments of varying weights (0.06 kg, 9 kg, 18 kg, and 27 kg) and load distributions. Decreased pelvic rotation found with an increase in weight implies decreased mobility by restricting the leg’s swing to propel the body forward. Increased ROM for pelvic tilt found with increased weight results from increased forward inclination suggesting an increased possibility for fatigue and musculoskeletal pain …

Drugs, Devices, And Desires: A Problem-Based Learning Course In The History Of Medicine, Sarah Levitt, Anne Mckeage, P. K. Rangachari

Interdisciplinary Journal of Problem-Based Learning

Problem-based learning (PBL) is well suited for courses in the history of medicine, where multiple perspectives exist and information has to be gleaned from different sources. A student, an archivist, and a teacher offer three perspectives about a senior level course where students explored the antecedents and consequences of medical technology. Two active learning strategies were used: (a) PBL to explore the historical basis of procedures used to diagnose, prevent and treat a single disease, tuberculosis, and (b) a concurrent inquiry-based component that permitted individual exploration of other medical technologies and demonstration of learning through diverse options (book reviews, conversations, …
