Introducing clinical laboratory science: CLS students help shape the future.

Abstract

OBJECTIVES: The profession of clinical laboratory science (CLS) is in dire need of increased exposure to young people. By introducing the clinical laboratory sciences to students at a critical point in their science education and by making it relevant to their lives, more choices are made available to them when considering future career options. With this in mind, the CLS faculty at Texas Tech University Health Sciences Center (TTUHSC) redesigned a recruitment program and developed it into one making use of CLS student knowledge, enthusiasm, and professionalism. CLS students were given the assignment of designing an entire curriculum for a ten day presentation of clinical laboratory science topics to middle and secondary school students. Following the presentations, participants in the program were asked to provide feedback regarding CLS student performance and overall opinion of their interest in clinical laboratory science. The objectives of this study were twofold: 1) to determine if educational methodologies could be appropriately applied by CLS students to present CLS disciplines to middle and high school students; and 2) to determine if the student presentation was successful in initiating interest in the CLS profession based on outcome measures. DESIGN: As a component of the CLS laboratory management course, CLS students were instructed in education methodologies including objective writing, teaching-unit preparation, and evaluation tool design. In the following semester, these students were divided into groups and assigned a specific CLS discipline that would then be presented to middle and secondary school students in a two week, 30 hour educational program. This program was offered by the TTUHSC CLS program in cooperation with the Institute for the Development and Enrichment of Advanced Learners (IDEAL) at Texas Tech University. The curriculum prepared by the CLS students (with faculty supervision) provided the framework for the present study. SETTING: Didactic instruction of the CLS students regarding objective writing, curriculum design, and preparation of evaluations was included as a component of a CLS laboratory management course. The educational program presented by IDEAL in conjunction with the TTUHSC CLS program within the School of Allied Health Sciences occurred in the CLS student laboratories located in Lubbock, Texas. PARTICIPANTS: TTUHSC senior CLS students in a 2 + 2 baccalaureate level CLS program acted as instructors in the educational program which was presented to middle and secondary school students from around the region. CLS program faculty served as supervisors of this program. MAIN OUTCOME MEASURES: Questionnaires with Likert-scaled responses were used to evaluate outcomes. These questionnaires regarded 1) faculty assessment of CLS student performance relative to instruction in education methods; 2) participant feedback on the effectiveness and competence of the CLS student instructors and overall appeal of the presented subject material; and 3) peer evaluations of attitude, contribution, and effort of the group members. RESULTS: CLS faculty strongly agreed that the CLS students demonstrated a high level of competence when writing objectives, planning age-appropriate curriculum and activities, and demonstrating a positive image of the profession. Regarding satisfaction of the IDEAL student participant, questionnaire responses demonstrated a high rate (84% or greater for middle school participants and 85% for high school students). The program design has been so successful that it has been implemented for several other programs offered by TTU and IDEAL. CONCLUSION: The education methods used in presenting the IDEAL program mirror those found in clinical and academic settings and is an effective technique to introduce CLS students to the varied aspects of educational methodology. The presentation by the CLS students also demonstrated that introduction of clinical laboratory science disciplines early in the education of middle and secondary school students leads to an interest in the CLS profession and to the desire to learn more about it.

Effect of temperature on the extraction kinetics and diffusivity of Cyclosporin A in the fungus Tolypocladium inflatum.

The influence of temperature on the extraction kinetics of Cyclosporin A (CyA) from the mycelia of Tolypocladium inflatum was examined in this study. The extraction of CyA from mycelia was performed in a 2-L stirred, baffled vessel using 30% v/v aqueous methanol. The temperature range used was from 5 to 45 degrees C. A linear relationship was found between the extraction yield of CyA and temperature. As the temperature increased, the yield of CyA increased with a maximum CyA yield of 18.3% obtained at 45 degrees C, which is 21.3% higher than the yield at 25 degrees C. The activation energy for the extraction of CyA from T. inflatum was found to be 36.7 kJ/mol, which indicates that the extraction of CyA from T. inflatum is controlled by both solubilization of CyA and diffusion of CyA through the solid phase of mycelia. The overall mass transfer coefficient, k(L)a(S), was found to increase from 1.02 x 10(-3) to 1.34 x 10(-2) s(-1) as the temperature increased from 5 to 45 degrees C. The effective diffusivity of CyA in the solid matrix of mycelia was found to increase from 1.05 x 10(-15) to 1.43 x 10(-14) m(2)/s as the temperature increased from 5 to 45 degrees C. A mathematical diffusion model was developed and was used to fit the experimental kinetic data of CyA extraction and determination of CyA effective diffusivities at different temperatures. This is the first time CyA diffusivities as a function of extraction temperature are reported in the literature.

Laboratory-confirmed non-O157 Shiga toxin-producing Escherichia coli--Connecticut, 2000-2005.

Shiga toxin-producing Escherichia coli (STEC) infection causes diarrhea that is often bloody and can result in potentially life-threatening hemolytic uremic syndrome (HUS). Escherichia coli O157:H7 is the most common cause of STEC infection in the United States, producing 73,000 illnesses annually, according to the last estimate in 1999. Unlike O157, however, little is known about the incidence of non-O157 strains. Because STEC other than O157 are not commonly identified, the incidence, trends, and epidemiology of non-O157 STEC are not well understood. To assess trends in Shiga toxin enzyme immunoassay (Stx EIA) testing by local clinical laboratories, the Connecticut Department of Public Health (CTDPH) analyzed results of confirmatory testing conducted in the state laboratory during 2000--2005. The findings indicated that a total of 403 STEC infections were reported by clinical laboratories in Connecticut, including 207 identified as STEC by Stx EIA testing alone, and that the use of Stx EIA increased from 2000 to 2005. Use of Stx EIA without prompt culture confirmation can delay or prevent serotyping and subtyping of isolates and detection of both O157 and non-O157 STEC outbreaks. Public health authorities in all states should ensure that clinical laboratories forward Stx EIA-positive specimens to the state laboratory for isolation and identification of STEC, as recommended by the Association of Public Health Laboratories and CDC.

Clinical use of laboratory tests for the identification of secondary forms of arterial hypertension.

The prevalence of secondary hypertension can be underestimated if appropriate tests are not performed. The importance of selecting patients with a high pre-test probability of secondary forms of hypertension is first discussed. The laboratory tests currently used for seeking a cause of hypertension are critically reviewed, with emphasis on their operative features and limitations. Strategies to identify primary aldosteronism, the most frequent form of secondary hypertension, and to determine its unilateral or bilateral causes are described. Treatment entails adrenalectomy in unilateral forms, and mineralocorticoid receptor blockade in bilateral forms. Renovascular hypertension is also a common, curable form of hypertension, that should be identified as early as possible to avoid the onset of cardiovascular target organ damage. The tests for its confirmation or exclusion are discussed. The various tests available for the diagnosis of pheochromocytoma, which is much rarer than the above but extremely important to identify, are also described, with emphasis on recent developments in genetic testing. Finally, the tests for diagnosing some rarer monogenic forms and other renal and endocrine causes of arterial hypertension are explored.
