Collaboration entre cliniciens et chercheurs autour de la «consultation systémique» : une situation de violence intrafamiliale

Cet article vise à illustrer la collaboration et l'enrichissement mutuel qu'apportent aux chercheurs et aux cliniciens l'utilisation de la «consultation systémique». Cette dernière, demandée soit spontanément par les parents, soit par le(s) thérapeute(s) qui suive(nt) la famille, a pour but l'évaluation des interactions familiales. Lors d'une première rencontre, les questions qui motivent les parents et/ou thérapeute(s) à consulter sont formulées et la famille est invitée à faire des jeux familiaux semi-standardisés qui sont filmés. Lors d'une deuxième rencontre réunissant les mêmes personnes, un visionnement d'extraits des films sert de base à une discussion ainsi qu'à l'élaboration de réponses aux questions posées, en partant des observations des chercheurs. Après une description de la consultation systémique standard (principes, objectifs, procédure et situations d'observation), une vignette clinique atypique, concernant des violences intrafamiliales, illustrera la variété et la richesse de ces consultations. Les observations micro et macro-analytiques des interactions données par les chercheurs, auxquelles s'ajoute la compréhension clinique des thérapeutes, montrent qu'une collaboration entre eux est fructueuse pour toutes les parties concernées.

Performance on a Virtual Reality Angled Laparoscope Task Correlates with Spatial Ability of Trainees

The aim of the present study was to investigate whether trainees' performance on a virtual reality angled laparoscope navigation task correlates with scores obtained on a validated conventional test of spatial ability. 56 participants of a surgery workshop performed an angled laparoscope navigation task on the Xitact LS 500 virtual reality Simulator. Performance parameters were correlated with the score of a validated paper-and-pencil test of spatial ability. Performance at the conventional spatial ability test significantly correlated with performance at the virtual reality task for overall task score (p < 0.001), task completion time (p < 0.001) and economy of movement (p = 0.035), not for endoscope travel speed (p = 0.947). In conclusion, trainees' performance in a standardized virtual reality camera navigation task correlates with their innate spatial ability. This VR session holds potential to serve as an assessment tool for trainees.

Could moderate alcohol consumption help prevent the metabolic syndrome and diabetes mellitus ?

Aim and purpose: Moderate alcohol consumption has been associated with lower risk of diabetes mellitus, but few data exist on the metabolic syndrome and on the metabolic impact of heavy drinking. The aim of our study was to investigate the complex relationship between alcohol and the metabolic syndrome and diabetes mellitus in a population-based study in Switzerland with high mean alcohol consumption. Design and methods: In 6188 adults aged 35 to 75, alcohol consumption was categorized as 0, 1-6, 7-13, 14-20, 21-27, 28-34 and >= 35 drinks/week or as nondrinkers, moderate (1-13 drinks), high (14-34 drinks) and very high (>= 35 drinks) alcohol consumption. The metabolic syndrome was defined according to the ATP-III criteria and diabetes mellitus as fasting glycemia >= 7 mmol/l or self-reported medication.We used multivariate analysis adjusted for age, gender, smoking status, physical activity and education level to determine the prevalence of the conditions according to drinking categories. Results: 73% (n = 4502) of the participants consumed alcohol, 16% (n = 993) were high drinkers and 2% (n = 126) very high drinkers. In multivariate analysis, alcohol consumption had a U-shaped relationship with the metabolic syndrome and diabetes mellitus. The prevalence of the metabolic syndrome significantly differed between nondrinkers (24%), moderate (19%), high (20%) and very high drinkers (29%) (P<= 0.005). The prevalence of diabetes mellitus also significantly differed between nondrinkers (6.0%), moderate (3.6%), high (3.8%) and very high drinkers (6.7%) (P<= 0.05). These relationships did not differ according to beverage types. Conclusions: The prevalence of the metabolic syndrome and diabetes mellitus decrease with moderate alcohol consumption and increase with heavy drinking, without differences according to beverage types. Recommending to limit alcohol consumption to 1-2 drinks/day might help prevent these conditions in primary care Metabolic Syndrome and Diabetes Mellitus.
