Catheter-related bacteremia and fungemia. Reliability of two methods for catheter culture.

The purpose of this study was to analyze 98 febrile patients with suspected catheter-related bacteremia (CRB) or fungemia (CRF) and compare two different methods, one semiquantitative (SQ) (Maki's method) and the other quantitative (Q) (modification of Brun-Buisson method) to determine each ability for diagnosing CRB. Twelve patients had CRB or CRF. The sensitivity, specificity, positive, and negative predictive values, and efficiency using the Maki method were 83%, 84%, 42%, 97%, and 83%, respectively. The same parameters using the other method were as follows: 92%, 84%, 44%, 99%, and 84%, respectively. Although the diagnostic reliability in each method was similar, the Maki method was quicker and easier to perform in clinical microbiology laboratories.

Recombinant antigens for specific and sensitive serodiagnosis of Latin American tegumentary leishmaniasis.

The diagnostic potential of recombinant leishmanial antigens for Latin American tegumentary leishmaniasis (LATL) was examined. Two Leishmania (Viannia) peruviana recombinant proteins, T26-U2 and T26-U4, were assessed by their reactivity to detect specific anti-leishmanial antibodies. Seventy-eight individual sera from persons with LATL, 39 from those with other diseases, and 10 negative control sera were tested by Western blotting and enzyme-linked immunosorbent assay. The sensitivity of the test using T26-U2 plus T26-U4 was similar to that obtained with whole parasite extract (92%). However, the specificity obtained using both recombinant antigens (87%) was higher than that of the whole parasite extract (65%). All tests using recombinant proteins (T26-U2, T26-U2 plus T26-U4 or T26-U4) had a higher positive predictive value (89%, 92% and 98%, respectively) than the value obtained using total parasites (81%). Eleven Colombian sera were also tested, and the results indicated that T26-U2 plus T26-U4 could be used successfully in Peru and in other Latin American countries.

A faculty case management practice: integrating teaching, service, and research.

Like many other schools, the faculty of the University of Oklahoma College of Nursing (OUCN) recently revised its baccalaureate and master's curricula to prepare students better for the evolving changes in the nursing profession and the health care job market. Our personal visions of needed changes, reviews of the literature, and feedback from nursing leaders and community employers supported the need for four significant changes. First, students needed more experiences in the community and clients' homes, with the aged, the chronically ill, and the disabled in all age brackets. Second, students needed greater familiarity with Medicare, Medicaid, and managed care, and more active involvement in the wise use of limited resources. Third, they needed more experience with interdisciplinary teams and with the management of care across sites and levels of acuity. Fourth, there was a need for more consistent integration of health promotion and research content into student learning related to emerging trends in health care and nursing practice.
