Case Study: Effect of Surgical Metal Implant on Single Frequency Bioelectrical Impedance Measures of an Athlete

This case study examined the influence of a surgical metal implant on the bioelectrical impedance analysis (BIA) readings of an athlete. Single‐frequency BIA using a tetrapolar electrode configuration was applied to both the right and left sides of a 23‐year‐old female jumper who had an 8 × 345 mm titanium alloy nail implanted in her left tibia. The metal implant reduced BIA resistance and reactance on the implanted side by 27 and 6 ohms, respectively. This reduction in impedance resulted in a 0.4 kg–1.9 kg increase in the estimate of fat‐free mass (FFM) depending on the prediction formula used. There was a concomitant decrease in the estimate of body fat percentage (%BF) with the underestimation ranging from 0.6% to 2.7% BF depending on the prediction formula. A metal implant of substantial size can alter the BIA reading. Technicians should apply BIA to the opposite side of the body when athletes present with a surgical implant in a limb

Non-Target Impacts of Strychnine Baiting to Reduce Pocket Gopher Populations on Forest Lands in the united States

Reforestation efforts are often severely hindered on sites that contain high populations of pocket gophers (Thmmysspp). Strychnine baiting is a technique used to suppress pocket gopher populations until seedlings are established. Strychnine bait is applied below ground in pocket gopher burrows, however, primary and secondary hazards remain a concern. A study to assess primary hazards indicated that some individual rodents died post strychnine baiting but there was not a long-term negative impact on non-target rodent populations. Possible secondary hazards reflect the potential for predators OT scavengers to encounter poisoned pocket gophers. Concerns that pocket gophers may surface before they succumb to the bait have been reduced through data acquired in pen trials. Most pocket gophers in trials with natural ground cover died in or near nest and all died below-ground. Carcasses of non-target species may pose some risk. These carcasses, however, are few and are thought to be consumed by insects within a few days. Trials are being conducted to evaluate the fate of these carcasses and to assess whether insects that feed on strychnine-containing carcasses pose a tertiary hazard

Effects of Ambient Particulate Matter on Aerobic Exercise Performance

Background/Objective: Wintertime thermal inversions in narrow mountain valleys create a ceiling effect, increasing concentration of small particulate matter (PM2.5). Despite potential health risks, many people continue to exercise outdoors in thermal inversions. This study measured the effects of ambient PM2.5 exposure associated with a typical thermal inversion on exercise performance, pulmonary function, and biological markers of inflammation. Methods: Healthy, active adults (5 males, 11 females) performed two cycle ergometer time trials outdoors in a counterbalanced design: 1) low ambient PM2.5 concentrations (/m3 ), and 2) an air quality index (AQI) ranking of “yellow.” Variables of interest were exercise performance, exhaled nitric oxide (eNO), c-reactive protein (CRP), forced vital capacity (FVC), and forced expiratory volume in 1 s (FEV1). Results: Despite a significant difference in mean PM2.5 concentration of 9.3 ± 3.0 mg/m3 between trials (p \u3c .001), there was no significant difference (p = .424) in the distance covered during low PM2.5 conditions (9.9 ± 1.7 km) compared to high PM2.5 conditions (10.1 ± 1.5 km). There were no clinically significant differences across time or between trials for eNO, CRP, FVC, or FEV1. Additionally, there were no dose-response relationships (p \u3e .05) for PM2.5 concentration and the measured variables. Conclusion: An acute bout of vigorous exercise during an AQI of “yellow” did not diminish exercise performance in healthy adults, nor did it have a negative effect on pulmonary function or biological health markers. These variables might not be sensitive to small changes from acute, mild PM2.5 exposur

First Semester BSN Students: Cognitive Appraisal & Perceived Stress

Cognitive appraisal and stress research has been applied to training stressors, creative arts, pregnancy, psychotherapy, academic, and sleep quality (Erschens et al.,2018; Martin, et al., 2018; Gonzalex-Ochoa, 2018; Wersebe et al., 2018; You-wei et al., 2018). The purpose of this investigation was to study the effects of stress and stressors experienced by first semester BSN undergraduate students. The Brief College Student Hassle Scale (BCSHC) measured stressors (Ward & Hay, 2015). Participants rated their school and personal stresss levels, and the area most stressful.https://fuse.franklin.edu/ss2018/1018/thumbnail.jp

LDEF data: Comparisons with existing models

The relationship between the observed cratering impact damage on the Long Duration Exposure Facility (LDEF) versus the existing models for both the natural environment of micrometeoroids and the man-made debris was investigated. Experimental data was provided by several LDEF Principal Investigators, Meteoroid and Debris Special Investigation Group (M&D SIG) members, and by the Kennedy Space Center Analysis Team (KSC A-Team) members. These data were collected from various aluminum materials around the LDEF satellite. A PC (personal computer) computer program, SPENV, was written which incorporates the existing models of the Low Earth Orbit (LEO) environment. This program calculates the expected number of impacts per unit area as functions of altitude, orbital inclination, time in orbit, and direction of the spacecraft surface relative to the velocity vector, for both micrometeoroids and man-made debris. Since both particle models are couched in terms of impact fluxes versus impactor particle size, and much of the LDEF data is in the form of crater production rates, scaling laws have been used to relate the two. Also many hydrodynamic impact computer simulations were conducted, using CTH, of various impact events, that identified certain modes of response, including simple metallic target cratering, perforations and delamination effects of coatings

Nursing Panel and Innovative, Interdisciplinary, Collaborative Non-Nursing Course Teaching Strategy

The innovative, interdisciplinary, collaborative teaching strategy is the Nursing Panel (NP) intervention. In the Cultural Competence in Healthcare course, this teaching strategy was designed by social sciences professor. The NP Intervention invites traditional and accelerated Bachelor of Science in Nursing (BSN) students to ask questions of full-time Registered Nurse (RN) Faculty regarding cultural and nursing profession topics. Four RN Faculty share information and professional stories in an engaging, interactive format.https://fuse.franklin.edu/ss2018/1047/thumbnail.jp

ASEA Redox Supplement Fails to Improve Aerobic Capacity and Ventilatory Threshold: A Double-Blind, Placebo-Controlled Study

The ASEA redox cell signaling supplement beverage has been commercially available for the past decade. Despite the market longevity of this supplement, athletic sponsorship, and anecdotal ergogenic claims, there is no independent, peer-reviewed research on its efficacy. The purpose of this study was to determine if ASEA improves aerobic capacity (VO2 max) and/or ventilatory threshold (VT) of physically active subjects. Eleven (6 females, 5 males) young adults (21.9 ± 3.9 yrs) performed 3 VO2 max tests: (a) baseline; (b) after 2 wks of supplementing with ASEA; and (c) after 2 wks of taking a placebo in a cross-over design. The treatment order was randomized and double-blind. The subjects consumed 4 oz∙d-1 (118 mL∙d -1) of the ASEA treatment according to the manufacturer’s recommendations. The subjects’ VO2 max values at baseline (55.0 ± 8.6 mL·kg-1 ·min-1), placebo (53.6 ± 9.1 mL·kg-1 ·min-1), and ASEA (53.7 ± 10.1 mL·kg-1 ·min-1) were not significantly different (P=0.172). Similarly, absolute VO2 max (P=0.436), time to reach VO2 max (P=0.955), VT as a percentage of VO2 max (P=0.678), and maximal heart rate (P=0.410) were not significantly different between trials. Contrary to the manufacturer’s claims, ASEA did not improve the aerobic performance of young, fit adults who supplemented with the product daily for 2 wks
