Effectiveness of interprofessional education in renal physiology curricula for health sciences graduate students.

The primary purpose of conducting an interprofessional education (IPE) experience during the renal physiology block of a graduate-level course was to provide basic science, physical therapy, and physician assistant graduate students with an opportunity to work as a team in the diagnosis, treatment, and collaborative care of a patient with acute kidney injury. The secondary purpose was to enhance the understanding of basic renal physiology principles with a patient case presentation of renal pathophysiology. The overall purpose was to assess the value of IPE integration within a basic science course by examining student perceptions and program evaluation. Graduate-level students operated in interprofessional teams while working through an acute kidney injury patient case. The following Interprofessional Education Collaborative subcompetencies were targeted: Roles/Responsibilities (RR) Behavioral Expectations (RR1, RR4) and Interprofessional Communication (CC) Behavioral Expectations (CC4). Clinical and IPE stimulus questions were discussed both within and between teams with assistance provided by faculty facilitators. Students were given a pre- and postsurvey to determine their knowledge of IPE. There were statistically significant increases from pre- to postsurvey scores for all six IPE questions for all students. Physical therapy and physician assistant students had a statistically significant increase in pre- to postsurvey scores, indicating a more favorable perception of their interprofessional competence for RR1, RR4, and CC4. No changes were noted in pre- to postsurvey scores for basic science graduate students. Incorporating planned IPE experiences into multidisciplinary health science courses represents an appropriate venue to have students learn and apply interprofessional competencies.

Concurrent validity and reliability of the Alberta Infant Motor Scale in infants at dual risk for motor delays.

Concurrent validity of scores for the Alberta Infant Motor Scale (AIMS) and the Peabody Developmental Gross Motor Scale-2 (PDGMS-2) was examined with a sample of 35 infants at dual risk for motor delays or disabilities. Dual risk was defined as low birthweight ( 9 months of age. Novice examiners' scores on both measures closely approximated those of experienced examiners (ICC range = .98 to .99). The results support concurrent validity of the AIMS and PDGMS-2 for infants at dual risk and have implications for using the AIMS in high-risk follow-up programs, particularly in relation to evaluating functional components of motor performance and ease of administration.

Use of anabolic steroids to attenuate the effects of glucocorticoids on the rat diaphragm.

BACKGROUND AND PURPOSE: Administration of glucocorticoids results in atrophy and contractile dysfunction in the rat diaphragm. Anabolic steroids may be useful in preventing atrophy and contractile dysfunction. The purpose of this study was to assess the effects of simultaneous administration of testosterone and glucocorticoids on morphological and contractile properties of the rat diaphragm. SUBJECTS: Eighty-eight adult female Sprague-Dawley rats were divided into 1 of 4 groups: a control group that was given sham injections for 13 days (CONT group, n=23), a group that was given prednisolone injections (0.5 mg/100 g) for 10 days (PRED group, n=23), a group that was given testosterone injections (0.5 mg/100 g) for 13 days (TEST group, n=18), and a group that was given a combination of prednisolone and testosterone injections (0.5 mg/100 g) for 10 and 13 days, respectively (COMBO group, n=23). METHODS: The animals were weighed daily, and drug doses were adjusted to changes in body mass. Twenty-four hours following the final injection, animals were weighed and sacrificed and the diaphragm was removed and weighed. A small strip of diaphragm was attached to a force transducer to determine normalized maximal isometric tetanic tension (PO). RESULTS: Body weights in the PRED group were decreased by 26% as compared with body weights in the CONT group, and body weights in the COMBO group were decreased by 11% as compared with body weights in the CONT group. Diaphragm weights in the PRED and COMBO groups were decreased by 22% and 12%, respectively, as compared with diaphragm weights in the CONT group. Normalized maximal isometric tetanic tension was decreased by 11% in the PRED group as compared with PO in both the CONT and TEST groups and was decreased by 13% as compared with PO in the COMBO group. There was no difference in PO among the CONT, TEST, and COMBO groups. DISCUSSION AND CONCLUSION: The results support the hypothesis that simultaneous administration of testosterone with glucocorticoids would prevent a decrease in PO. The results indicate that simultaneous administration of testosterone with glucocorticoids prevented the loss in body weight and partially attenuated the loss in diaphragm weight that is commonly observed when glucocorticoids are given alone. These data support the notion that testosterone may be useful in the prevention of glucocorticoid-induced atrophy.

Cardiac myosin phenotype remodelling following adrenodemedullectomy and chronic 6-hydroxydopamine in male Sprague-Dawley rats.

BACKGROUND: An increase was previously found in relative beta myosin heavy chain (MyHC) in the right ventricle of rats following thoracic spinal transection. It was hypothesized that the MyHC remodelling that was observed might be due, in part, to autonomic influences on the right ventricle. OBJECTIVE: To evaluate cardiac myosin phenotype following 21 days of reduced sympathetic activity. METHODS: Adult male Sprague-Dawley rats underwent either adrenodemedullectomy/chemical sympathectomy (SX) or sham operation/sham injection (CN). Twenty-one days following surgery, the animals were sacrificed and both ventricles were harvested. The ventricles were denatured and run on sodium dodecyl sulfate-polyacrylamide gel electrophoresis for identification of MyHC isoforms. RESULTS: SX resulted in a significant decline in catecholamines. In the right ventricle, beta MyHC ratio was twofold higher in SX animals than in CN rats, but there was no difference between groups in beta MyHC concentration in the left ventricle (P<0.05). Uniquely, we found a decrease in relative alpha MyHC in the right ventricle but no change in the myosin phenotype in the left ventricle. CONCLUSIONS: These data potentially indicate that MyHC concentrations in the left ventricle are less sensitive than the right ventricle to decreased sympathetic activity.
