Case-by-Collaboration: An Adaptable Soft Skills-Based Educational Model for Health Disciplines

Purpose: The purpose of this study was two-fold and consisted of the development of a skills-based model for Case-by-Collaboration (CBC) and the collection of qualitative data from students and teachers aimed at answering the research question: What skills do individuals (students) apply during the completion of a hypothetical medical laboratory management-based Case-by-Collaboration capstone project? Method: A consensual qualitative research design was selected for this study. Students and their instructors from three Medical Laboratory Science programs located in Texas, New York, and Missouri were recruited. Students were given a case that centers on the fictitious Cheapskate Health Maintenance Organization (HMO). The project culminated when each team presented their proposal to become the sole provider of laboratory testing services to the Cheapskate HMO Board of Directors (BOD). The project was initially designed to be accessed and completed online, where students from different institutions would come together and remotely complete the requirements. Data were collected through in-person observations of the final presentation, semi-structured interviews with students and instructors, and analysis of project documents. Data was coded, and transcripts were reviewed numerous times. Two strategies were employed to ensure the integrity of the study. First, the coded data were examined across the data collection strategies, transcripts containing the data, and the themes identified by a researcher and an outside auditor. Secondly, an audit trail was established to document how the data were collected and analyzed, along with documentation of the thought processes used in the data interpretation phase of the project. Results: The current study analyzed responses from 36 students and 5 instructors across the three data collection sites. Seven themes, in the form of skill sets, were identified in the data analyzed:1) information technology, 2) collaboration/team building, 3) verbal and written communication, 4) clinical reasoning, 5) creativity, 6) managerial, and 7) research/investigative. Conclusion: These results suggest the CBC can develop desirable soft skills. This model can be transferrable and apply to CBCs independent of the studied content. Thus, the CBC is an innovative model to teach soft skills across health disciplines

Effects of dietary acid load on exercise metabolism and anaerobic exercise performance

Dietary acid load, quantified as the potential renal acid load (PRAL) of the diet, affects systemic pH and acid-base regulation. In a previous cross-sectional study, we reported that a low dietary PRAL (i.e. alkaline promoting diet) is associated with higher respiratory exchange ratio (RER) values during maximal exercise. The purpose of the present study was to confirm the previous findings with a short-term dietary intervention study. Additionally, we sought to determine if changes in PRAL affects submaximal exercise RER (as a reflection of substrate utilization) and anaerobic exercise performance. Subjects underwent a graded treadmill exercise test (GXT) to exhaustion and an anaerobic exercise performance test on two occasions, once after following a low-PRAL diet and on a separate occasion, after a high-PRAL diet. The diets were continued as long as needed to achieve an alkaline or acid fasted morning urine pH, respectively, with all being 4-9 days in duration. RER was measured during the GXT with indirect calorimetry. The anaerobic performance test was a running time-to-exhaustion test lasting 1-4 min. Maximal exercise RER was lower in the low-PRAL trial compared to the high-PRAL trial (1.10 ± 0.02 vs. 1.20 ± 0.05, p = 0.037). The low-PRAL diet also resulted in a 21% greater time to exhaustion during anaerobic exercise (2.56 ± 0.36 vs. 2.11 ± 0.31 sec, p = 0.044) and a strong tendency for lower RER values during submaximal exercise at 70% VO(2)max (0.88 ± 0.02 vs. 0.96 ± 0.04, p = 0.060). Contrary to our expectations, a short-term low-PRAL (alkaline promoting) diet resulted in lower RER values during maximal-intensity exercise. However, the low-PRAL diet also increased anaerobic exercise time to exhaustion and appears to have shifted submaximal exercise substrate utilization to favor lipid oxidation and spare carbohydrate, both of which would be considered favorable effects in the context of exercise performance
