BackgroundShort term illnesses, usually caused by respiratory or gastrointestinal diseases are disruptive to productivity and there is relatively little focus on preventative measures. This study examined the effect of the probiotic Lactobacillus reuteri protectis (ATCC55730) on its ability to improve work-place healthiness by reducing short term sick-leave caused by respiratory or gastrointestinal infections.Methods262 employees at TetraPak in Sweden (day-workers and three-shift-workers) that were healthy at study start were randomised in a double-blind fashion to receive either a daily dose of 108 Colony Forming Units of L. reuteri or placebo for 80 days. The study products were administered with a drinking straw. 181 subjects complied with the study protocol, 94 were randomised to receive L. reuteri and 87 received placebo.ResultsIn the placebo group 26.4% reported sick-leave for the defined causes during the study as compared with 10.6% in the L. reuteri group (p < 0.01). The frequency of sick-days was 0.9% in the placebo group and 0.4% in the L. reuteri group (p < 0.01). Among the 53 shift-workers, 33% in the placebo group reported sick during the study period as compared with none in the L. reuteri group(p < 0.005).

This paper presents a heuristic model for the dynamics of psychoanalytic supervision. It is not a manual for how to perform supervision, but a model for how to identify and think about the complex elements and forces influencing the supervisory process. The point of departure is that psychoanalysis is a composite craft in which seemingly contrary elements like strict rules and creative intuitions have their place and interact. Several aspects of supervision are discussed: aims, learning processes, teaching methods, relationship, emotional atmosphere and evaluation. Competence is given a pivotal place in the model. The main feature of the model is that these aspects of supervision are all seen as suspended in a field of dynamic tensions between phenomena in real or apparent opposition. One example of this is the tension in the supervisory relationship between supervisor as instructor acting as an authority for the candidate whilst being a mentor fostering autonomy in the candidate. It is argued that related kinds of dynamics characterize several aspects of psychoanalytic supervision and that these tensions are inherent in analytic work. In conclusion a key word picture of the model is presented.
