Medical students' skills and needs for training in breaking bad news.

This study assessed medical students' perception of individual vs. group training in breaking bad news (BBN) and explored training needs in BBN. Master-level students (N = 124) were randomised to group training (GT)-where only one or two students per group conducted a simulated patient (SP) interview, which was discussed collectively with the faculty-or individual training (IT)-where each student conducted an SP interview, which was discussed during individual supervision. Training evaluation was based on questionnaires, and the videotaped interviews were rated using the Roter Interaction Analysis System. Students were globally satisfied with the training. Still, there were noticeable differences between students performing an interview (GT/IT) and students observing interviews (GT). The analysis of the interviews showed significant differences according to scenarios and to gender. Active involvement through SP interviews seems required for students to feel able to reach training objectives. The evaluation of communication skills, revealing a baseline heterogeneity, supports individualised training.

Vitellogenin genes A1 and B1 are linked in the Xenopus laevis genome.

Genomic clones containing the Xenopus laevis vitellogenin gene B1 have been isolated from DNA libraries and characterized by heteroduplex mapping in the electron microscope, restriction endonuclease analysis, and in vitro transcription in a HeLa whole-cell extract. Sequences from the 3'-flanking region of the previously isolated A1 vitellogenin gene were found in the 5'-flanking region of this B1 gene. Thus, the two genes are linked, with 15.5 kilobase pairs of DNA between them. Their length is about 22 kilobase pairs (A1 gene) and 16.5 kilobase pairs (B1 gene) and they have the following arrangement: 5'-A1 gene-spacer-B1 gene-3'. The analysis of heteroduplexes formed between the two genes revealed several regions of homology. Both genes are in the same orientation and, therefore, are transcribed from the same DNA strand. The possible events by which the vitellogenin gene family arose in Xenopus laevis are discussed.
