Résumé : Lagrangian analyses of a global ocean circulation model quantify the salinity changes experienced by the warm limb of the thermohaline circulation during the northward flow to the Atlantic deep convection regions. 6 Sv out of the estimated 10-Sv transfer from 45 degrees S to 47 degrees N flow through regions of prevailing surface evaporation: the southern and northern formation regions of Salinity Maximum Water and the Gulf of Cadiz/Mediterranean Sea domain. The remaining transport gains salinity through mixing with adjacent waters. As much as 6 Sv flow through the low-salinity surface mixed layer at the latitudes of the ITCZ whose effect annihilates that of the southern region of Salinity Maximum Water. Most of the salinity increase corresponds to the transformation of South to North Atlantic Central Water, with strong diapycnal transfers for the water that intersects the high and low salinity regions, and nearly isopycnal modifications for the water that avoids these regions.

OBJECTIVES: To compare the quality of life (QoL) in three groups of workers suffering or not from shoulder pain (SP) lasting more than one month during the preceding 12 months. METHOD: Between 2002-2005, 3710 workers were randomly included in a French surveillance system of work-related musculoskeletal disorders. In 2007, 2332 responded to a follow-up questionnaire, 2049 were still active. Workers completed the Nordic Questionnaire to assess SP and the SF-36 for QoL. Three groups were defined according to health status at follow-up: Group 1: workers without SP (men: 87.9%; women: 79.2%) Group 2: workers with SP without neck, elbow and hand/wrist pain lasting more than one month during the preceding 12 months (men: 4.2%; women: 6.0%) Group 3: workers with SP and neck, elbow or hand/wrist pain lasting more than one month during the preceding 12 months (men 7.9%; women 14.8%) The mean scores of SF-36 were compared with Kruskall-Wallis test and post-hoc comparisons were performed. Analyses were stratified by gender. RESULTS: Workers in group 2 had lower scores of physical health compared to workers in group 1, whatever the gender. Workers in group 3 had lower scores of physical and mental health compared to workers in group 1. Two dimensions of mental health in men and the four dimensions of physical health and one dimension of mental health in women had lower scores in group 3 compared to group 2. CONCLUSIONS: Workers with SP and upper-limb pain have poorer QoL compared to workers without SP and workers with SP without upper-limb pain.

Résumé : International audience
Background Mycobacterium ulcerans infection is the third most common mycobacterial disease in the world after tuberculosis and leprosy. To date, transmission pathways from its environmental reservoir to humans are still unknown. In South America, French Guiana has the highest reported number of M ulcerans infections across the continent. This empirical study aimed to characterise the epidemiology of M ulcerans infection in French Guiana between 1969 and 2013.MethodsData were collected prospectively mainly by two dermatologists at Cayenne Hospital’s dermatologydepartment between Jan 1, 1969, and Dec 31, 2013, for age, date of diagnosis, sex, residence, location of the lesion,type of lesion, associated symptoms, and diagnostic method (smear, culture, PCR, or histology) for all confirmed andsuspected cases of M ulcerans. We obtained population data from censuses. We calculated mean M ulcerans infectionincidences, presented as the number of cases per 100 000 person-years.Findings 245 patients with M ulcerans infections were reported at Cayenne Hospital’s dermatology department duringthe study period. M ulcerans infection incidence decreased over time, from 6·07 infections per 100 000 person-years(95% CI 4·46–7·67) in 1969–83 to 4·77 infections per 100 000 person-years (3·75–5·79) in 1984–98 and to3·49 infections per 100 000 person-years (2·83–4·16) in 1999–2013. The proportion of children with infections alsodeclined with time, from 42 (76%) of 55 patients in 1969–83 to 26 (31%) of 84 in 1984–98 and to 22 (21%) of 106 in1999–2013. Most cases occurred in coastal areas surrounded by marshy savannah (incidence of 21·08 per100 000 person-years in Sinnamary and 21·18 per 100 000 person-years in Mana). Lesions mainly affected limbs (lowerlimbs 161 [66%] patients; upper limbs 60 [24%] patients). We diagnosed no bone infections.Interpretation The decrease of M ulcerans infection incidence and the proportion of children with infections over a45 year period in this ultra-peripheral French territory might have been mostly driven by improving living conditions,prophylactic recommendations, and access to health care.
