This paper notes that a careful case definition of workers with previous history of low-back pain (LBP) is needed to better characterize sub-groups based on their recurrences profile. Workers with highly recurrent LBP may require a stepped secondary prevention in order to prevent recurrences and sick leave. The value of a workplace component reducing physical and psychosocial risks in secondary prevention of LBP must be explored.

Health outcomes showed that influenza disease burden in young French children is similar to that observed in North America. An active vaccination strategy would have strongly reduced the burden of influenza and lowered antibiotic use. Continuous efforts are needed to reach requirements of our influenza vaccination policy.

This randomized tandem trial showed lower adenoma miss rates and higher adenoma detection rates for the newer 190 colonoscopes compared with the 160/5 series. These results suggest that it takes multiple improvements, such as those implemented over 2 instrument generations, before an effect on adenoma (miss) rate can be observed.
