Teaching self-awareness enhances learning about patient-centered interviewing.

PURPOSE: To evaluate the effect of intensive attitudinal training on residents' learning the patient-centered interviewing skills required to establish a healthy provider-patient relationship and to communicate effectively. METHOD: While teaching 53 residents patient-centered interviewing skills, the authors also trained them to recognize previously unrecognized, negative attitudes that interfered with learning the skills. The authors, using an iterative, consensus-building process based on the residents' performances and personality data, identified a spectrum of responses to the educational intervention. Barriers to and facilitators of mastery of skills were analyzed and this information was used to help residents overcome skill deficits. RESULTS: To varying degrees, 44 residents became aware of previously unrecognized attitudes to the extent that they improved their patient-centered interviewing skills. Six residents failed to develop awareness of negative attitudes and showed little learning and clinical use of the interviewing skills being taught. Three residents who rapidly developed superb interviewing skills showed no negative attitude towards using them. CONCLUSIONS: Pending a confirmatory hypothesis-testing study, the authors believe that, as residents learn how to conduct patient-centered interviews, training in awareness of interfering attitudes should accompany training in skills.

Control of muscle proteolysis in insects.

In metamorphosing insects entire muscle masses may be destroyed within a matter of hours. The breakdown is controlled by neural and endocrine mechanisms; more recent evidence suggests tha a decrease in availability of oxygen occurs shortly prior to the onset of rapid involution. There are at least two phases of lysis, the slower first phase occurring in functioning muscle. Electron microscopic evidence suggests an early change in the morphology of the Z-line, followed several hours later by dissolution of the myofilaments. During the phase of rapid involution, a 60,000--70,000 dalton protein appears transiently in the tissue. Current evidence suggests that the rate-limiting step in the degradation of myosin is reduction to this presumed fragment; beyond this point, the muscle proteins are rapidly degraded to amino acids or small peptides.
