Training medical students to conduct motivational interviewing: a randomized controlled trial.

OBJECTIVE: To examine the effectiveness of motivational interviewing (MI) training among medical students. METHODS: All students (n=131) (year 5) at Lausanne Medical School, Switzerland were randomized into an experimental or a control group. After a training in basic communication skills (control condition), an 8-h MI training was completed by 84.8% students in the exprimental group. One week later, students in both groups were invited to meet with two standardized patients. MI skills were coded by blinded research assistants using the Motivational Interviewing Treatment Integrity 3.0. RESULTS: Superior MI performance was shown for trained versus control students, as demonstrated by higher scores for "Empathy" [p<0.001] and "MI Spirit" [p<0.001]. Scores were similar between groups for "Direction", indicating that students in both groups invited the patient to talk about behavior change. Behavior counts assessment demonstrated better performance in MI in trained versus untrained students regarding occurences of MI-adherent behavior [p<0.001], MI non-adherent behavior [p<0.001], Closed questions [p<0.001], Open questions [p=0.001], simple reflections [p=0.03], and Complex reflections [p<0.001]. Occurrences were similar between groups regarding "Giving information". CONCLUSION: An 8-h training workshop was associated with improved MI performance. PRACTICE IMPLICATIONS: These findings lend support for the implementation of MI training in medical schools.

L'entretien motivationnel, une nouvelle "panacée" dans la prise en charge de patients toxicodépendants ? Une revue de littérature [Motivational interviewing, the new "panacea" for treatment of substance use disorders ? A review of literature]

Cet article aborde l'entretien motivationnel (EM), considéré comme un style thérapeutique centré sur le client et directif, visant à développer la motivation au changement par l'exploration et la résolution de l'ambivalence (Miller, W.R., Rollnick, S., 2002. Motivational interviewing: preparing people for change. The Guilford Press, New York, p. 25). Après une brève présentation théorique de ce style thérapeutique, nous présentons un survol des principaux résultats empiriques relatifs à la question de son efficacité dans la prise en charge des troubles liés à l'utilisation de substances psychoactives. Malgré un corpus important de travaux qui mettent en évidence les effets de l'EM, la question des « ingrédients actifs » reste encore relativement peu explorée. Quelques hypothèses permettant de mieux comprendre le succès de l'EM sont évoquées.

Transposition of great arteries and single coronary artery: a new surgical technique for the arterial switch operation.

A single coronary artery can complicate the surgical technique of arterial switch operations, impairing early and late outcomes. We propose a new surgical approach, successfully applied in a 2.1 kg neonate, aimed at reducing the risk of early and late compression and/or distortion of the newly constructed coronary artery system.

Mini invasive skeletal muscle biopsy technique with a tri-axial end cut needle.

OBJECTIVE: Skeletal Muscle Biopsy is a minor surgical procedure for the diagnosis of different neuromuscular pathological conditions and has recently gained popularity also in the research field of age-related muscular modifications and sarcopenia. Few studies focused on the application of mini-invasive muscular biopsy in both normal and pathological conditions. The aim of our study was to describe a mini invasive ultrasound-guided skeletal muscular biopsy technique in complete spinal cord injured (SCI) patients and healthy controls with a tri-axial end-cut needle. PATIENTS AND METHODS: Skeletal muscle biopsies were collected from 6 chronic SCI patients and 3 healthy controls vastus lateralis muscle with a tri-axial end cut needle (Biopince© - Angiotech). Muscle samples were stained for ATPase to determine fibers composition, moreover, gene expression of cyclooxygenase-1 (COX-1) and prostaglandin E2 receptor has been analyzed by Real Time RT-PCR. RESULTS: All the procedures were perfomed easily without failures and complications. Control tissue was macroscopically thicker than SCI one. Control specimen displayed an equal distribution of type I and type II fibers, while SCI sample displayed a prevalence of type II fibers SCI specimen displayed a significant reduction in COX-1 gene expression. This mini-invasive approach was easy, accurate and with low complication rate in performing skeletal muscle biopsy in both SCI patients and controls. CONCLUSIONS: This technique could be useful in conditions in which the overall quantity of specimen required is small like for molecular biology analysis. For histological diagnostic purposes and/or conditions in which the original tissue is already pathologically modified, this technique should be integrated with more invasive techniques.
