The care of women requesting induced abortion: evidence-based clinical guideline number 7

La guía RCOG sobre el cuidado de las mujeres que solicitan aborto inducido fue publicada por primera vez en el año 2000. Una versión actualizada siguió esta pauta en 2004, hasta que esta revisión tuvo lugar durante 2010 y 2011

Improving care of women at risk of unsafe abortion: implementing a risk-reduction model at the Uruguayan-Brazilian border

OBJECTIVE: To describe the initial stages of the implementation of a risk-reduction model designed by Iniciativas Sanitarias to shield women from unsafe abortion in a traditional community on the Uruguay-Brazil border. METHODS: This mixed-design study was conducted first between 22 and 26 March 2010, and then between 2 and 7 May 2011, in Rivera, Uruguay, to gather information from women seen at health centers, healthcare providers, and local policy makers before the project started and midway through the project. RESULTS: At baseline most women and providers considered abortion justifiable only on narrow grounds, yet favored the implementation of a risk-reduction model that would include preabortion as well as postabortion counseling, the former providing information on different abortion methods and their risks. By the midterm assessment, the counseling service had assisted 87 women with unwanted pregnancies. Of the 52 who came for a postabortion visit, 50 had self-administered misoprostol, with no complications. Women were highly satisfied with the counseling. At baseline, misoprostol seemed to be available from both pharmacists and informal sellers. At midterm, it was still available from informal vendors but pharmacists said they did not provide misoprostol. The risk-reduction initiative heightened public attention to the abortion issue but the controversy it generated did not seriously impede its implementation. CONCLUSION: It is feasible to implement the proposed risk-reduction model in a traditional community such as Rivera, not only in Uruguay but in any country irrespective of its abortion laws.

An integrated high-resolution stratigraphy and orbital tuning is presented for the Loulja sections located in the Bou Regreg area on the Atlantic side of Morocco. The sections constitute the upward continuation of the upper Messinian Ain el Beida section and contain a well-exposed, continuous record of the interval straddling the Miocene-Pliocene (M-P) boundary. The older Loulja-A section, which covers the interval from ~5.59 to 5.12 Ma, reveals a dominantly precession-controlled color cyclicity that allows for a straightforward orbital tuning of the boundary interval and for detailed cyclostratigraphic correlations to the Mediterranean; the high-resolution and high-quality benthic isotope record allows us to trace the dominantly obliquity-controlled glacial history. Our results reveal that the M-P boundary coincides with a minor, partly precession-related shift to lighter "interglacial" values in d18O. This shift and hence the M-P boundary may not correlate with isotope stage TG5, as previously thought, but with an extra (weak) obliquity-controlled cycle between TG7 and TG5. Consequently, the M-P boundary and basal Pliocene flooding of the Mediterranean following the Messinian salinity crisis are not associated with a major deglaciation and glacio-eustatic sea level rise, indicating that other factors, such as tectonics, must have played a fundamental role. On the other hand, the onset of the Upper Evaporites in the Mediterranean marked by hyposaline conditions coincides with the major deglaciation step between marine isotope stage TG12 and TG11, suggesting that the associated sea level rise is at least partly responsible for the apparent onset of intermittently restricted marine conditions following the main desiccation phase. Finally, the Loulja-A section would represent an excellent auxiliary boundary stratotype for the M-P boundary as formally defined at the base of the Trubi marls in the Eraclea Minoa section on Sicily.

Geochemistry and position of turbidites in the Cap Timiris Canyon off Mauritania

This study of sediments from the Cap Timiris Canyon demonstrates that geochemical data can provide reliable age-depth correlation even of highly turbiditic cores and attempts to improve our understanding of how turbidite emplacement is linked to climatic-related sea-level changes. The canyon incises the continental margin off NW Africa and is an active conduit for turbidity currents. In sediment cores from levee and intrachannel sites turbidites make up 6-42% of sediment columns. Age models were fitted to all studied cores by correlating downcore element data to dated reference cores, once turbidite beds had been removed from the dataset. These age models enabled us to determine turbidite emplacement times. The Cap Timiris Canyon has been active at least over the last 245 kyr, with turbidite deposition seemingly linked to stage boundaries and glacial stages. The highly turbiditic core from the intrachannel site postdates to ~15 kyr and comprises Holocene and late Pleistocene sediments. Turbidite deposition at this site was associated especially with the rapid sea-level rise at the Pleistocene/Holocene transition. During the Holocene, turbidity current activity decreased but did not cease.
