Predicting Insulin Pump Therapy Settings, Riccardo L. Ferraro, David Grijalva, Alex Trahan

SMU Data Science Review

Millions of people live with diabetes worldwide [7]. To mitigate some of the many symptoms associated with diabetes, an estimated 350,000 people in the United States rely on insulin pumps [17]. For many of these people, how effectively their insulin pump performs is the difference between sleeping through the night and a life threatening emergency treatment at a hospital. Three programmed insulin pump therapy settings governing effective insulin pump function are: Basal Rate (BR), Insulin Sensitivity Factor (ISF), and Carbohydrate Ratio (ICR). For many people using insulin pumps, these therapy settings are often not correct, given their physiological needs. While …

Simulated Patients’ Perspectives Of And Perceived Role In Medical Students’ Professional Identity Development, Michelle Mclean, Patricia Johnson, Sally Sargeant, Patricia Green

Patricia Johnson

Introduction: Much has been written about medical students’ professional identity formation, the process of “becoming” a doctor. During their training, medical students interact with a range of teachers and trainers. Among these are simulated patients (SPs) who role-play patients, assisting students with their communication, procedural, and physical examination skills. With SPs regularly interacting with students, this qualitative study explored their views of students’ emerging professional identities at one Australian medical school. SPs’ contributions to developing professional identities were also explored.

Methods: Fourteen SPs were interviewed individually or in pairs. After template analysis of the transcripts using a priori themes, a …

Comparison Of Three Different Nickel-Titanium Endodontic Rotary Systems In Shaping Simulated S-Shaped Canals, Elineida Perez

Master's Theses (2009 -)

Introduction: Preparation error may result during mechanical instrumentation because of the complex anatomy of the root canal. Thus, flexibility and resistance to fracture are ideal properties that endodontic instruments should have. The aim of the study was to compare the shaping ability of three different nickel-titanium rotary instruments in simulated S-shape root canals by measuring transportation and canal volume change CVC. Materials and Methods: A total of 60 S-shaped canals in resin blocks were randomly allocated into 3 groups (n=20): Vortex Blue (Dentsply-Tulsa Dental Specialties), HyFlex CM (Coltène/Whaledent) and EndoSequence (Brasseler USA). Canals were filled with dye and secured in …

Deconstructing Anesthesia Handoffs During Simulated Intraoperative Anesthesia Care, Jason S. Lowe

Theses and Dissertations

Anesthesia patient handoffs are a vulnerable time for patient care and handoffs occur frequently during anesthesia care. Communication failures contribute to patient harm during anesthesia patient handoffs. The Joint Commission has recognized the potential for communication failure during patient handoffs and has recommended processes to improve handoff safety. Handoffs are made more difficult by latent conditions such as time constraints, pressure and distractions, which often result in incomplete or inaccurate handoff reports. This nonexperimental, correlation study identified the latent conditions that occur during the handoff process and their relationship to the quality of the handoff. This research shows an inverse …

Simulated Angular Head Oscillation Enhances Vection In Depth, Juno Kim, Stephen Palmisano, Frederick Bonato

Faculty of Health and Behavioural Sciences - Papers (Archive)

Research has shown that adding simulated linear head oscillation to radial optic flow displays enhances the illusion of self-motion in depth (ie linear vection). We examined whether this oscillation advantage for vection was due to either the added motion parallax or retinal slip generated by insufficient compensatory eye movement during display oscillation. We constructed radial flow displays which simulated 1 Hz horizontal linear head oscillation (generates motion parallax) or angular head oscillation in yaw (generates no motion parallax).We found that adding simulated angular or linear head oscillation to radial flow increased the strength of linear vection in depth. Neither type …

Horizontal Fixation Point Oscillation And Simulated Viewpoint Oscillation Both Increase Vection In Depth, Stephen Palmisano, Juno Kim, Tom C. A Freeman

Faculty of Health and Behavioural Sciences - Papers (Archive)

Previous research has shown that vection can be enhanced by adding horizontal simulated viewpoint oscillation to radial flow. Adding a horizontally oscillating fixation target to purely radial flow induces a superficially similar illusion of self-motion, where the observer's perceived heading oscillates left and right as their eyes pursue the moving target. This study directly compared the vection induced by these two conditions for the first time. Adding fixation point oscillation and simulated viewpoint oscillation to radial flow were both found to improve vection (relative to no oscillation control displays). Neither vection advantage could be explained in terms of differences in …

Simulated Viewpoint Jitter Shakes Sensory Conflict Accounts Of Vection, Stephen A. Palmisano, Robert S Allison, Juno Kim, Frederick Bonato

Faculty of Health and Behavioural Sciences - Papers (Archive)

Sensory conflict has been used to explain the way we perceive and control our self-motion, as well as the aetiology of motion sickness. However, recent research on simulated viewpoint jitter provides a strong challenge to one core prediction of these theories — that increasing sensory conflict should always impair visually induced illusions of self-motion (known as vection). These studies show that jittering self-motion displays (thought to generate significant and sustained visual–vestibular conflict) actually induce superior vection to comparable non-jittering displays (thought to generate only minimal/transient sensory conflict). Here we review viewpoint jitter effects on vection, postural sway, eye-movements and motion …

Why Do Medical Students Volunteer To Train Simulated Patients? A Qualitative Evaluation Of Motivations And Incentives, E Ashcroft, I Potter, J Bushnell

Faculty of Science, Medicine and Health - Papers: part A

The willingness to actively volunteer is an expected trait of medical students. Their compliance to participate in teaching and learning interventions is well described in the medical education literature The purpose of this investigation is to determine whether medical students' motivations to volunteer are congruent with motivational drives of other community members. We recruited eighteen (18) medical students, who contributed to the 2010 patient volunteer training as interview partners. One focus of their involvement was to develop feedback skills in newly recruited simulated patients. Ten (10) of these students participated in our audio-recorded focus group interviews. A thematic analysis of …

Evolution Of Reciprical Teaching And Learning: Medical Students And Simulated Patients Training In Partnership, E Ashcroft, I Potter, J Bushnell

Faculty of Science, Medicine and Health - Papers: part A

Training simulated patients effectively is vital for the success of the patient volunteer programme in the Graduate School of Medicine at the University of Wollongong. Globally, simulated patients play an essential role in contemporary medical education. Yet, there is a significant gap in the research literature regarding their training and the impact of their feedback on student learning. In 2010, our 2nd and 3rd year medical students replicated realistic interview situations as part of our simulated patient training. This intervention allowed patient volunteers to give feedback but also to receive feedback on their feedback giving skills from students. During these …

Effects Of Simulated Viewpoint Jitter On Visually Induced Postural Sway, Stephen A. Palmisano, Gavin J. Pinniger, April Ash, Julie R. Steele

Faculty of Health and Behavioural Sciences - Papers (Archive)

In this study we examined the effects of simulated horizontal and vertical viewpoint jitter on the vection and postural sway induced by radial patterns of optic flow. During each trial, observers were exposed sequentially to 20 s periods of radially expanding flow, radially contracting flow, and static visual scenes. For half the trials, simulated viewpoint jitter was added to the radially expanding/contracting optic flow patterns. In experiment 1, we found that, while this jitter increased the backward postural sway induced by radial expansion, it actually decreased forward postural sway induced by radial contraction. However, in experiment 2 we found that …

A Comparison Of Five Radiographic Systems To D-Speed Film In The Detection Of Artificial Bone Lesions, David Lloyd Hadley

Theses and Dissertations

The purpose of this study was to compare three direct digital sensors (Kodak 6100, Schick CDR, and Dexis PerfectSize), a phosphor plate system (OpTime), and F-speed film to standard D-speed film in the detection of artificial bone lesions prepared in mandible bone sections. Multiple artificial bone lesions were prepared at varying depths in the cortical bone. Specimens were imaged with six different radiographic systems. Radiographs were randomly presented to nine different observers. A logistic regression analysis indicated that the ability of the different radiographic systems to detect the bone lesions was significantly different at the mean percentage of cortical bone …

Visual Perception Of Touchdown Point During Simulated Landing, Stephen A. Palmisano, Barbara Gillam

Faculty of Health and Behavioural Sciences - Papers (Archive)

Experiments examined the accuracy of visual touchdown point perception during oblique descents (1.5^o-15^o) toward a ground plane consisting of (a) randomly positioned dots, (b) a runway outline, or (c) a grid. Participants judged whether the perceived touchdown point was above or below a probe that appeared at a random position following each display. Although judgments were unacceptably imprecise and biased for moving dot and runway displays, accurate and unbiased judgments were found for griddisplays. It is concluded that optic flow per se does not appear to be sufficient for a pilot to land an airplane and …
