The Albian-Cenomanian sediments in Holes 627B and 635B contain diverse dinoflagellate-cyst assemblages, which show affinities with coeval assemblages from offshore Morocco and northwest Europe. A total of 34 samples were analyzed from the shallow-water platform sediments and neritic marly chalk of Hole 627B and from the argillaceous chalk and limestone of Hole 635B. Dinoflagellate cysts indicate that the top of the shallow-water platform drilled at Hole 627B must be attributed to the late Albian. Dinocysts also date the drowning of the carbonate platform of the Blake Plateau. This drowning started in the latest Albian (Vraconian) and continued into the Cenomanian. The site area changed from an inner to intermediate or outer(?) neritic environment. The area around Hole 635B from the late Albian appears to have been situated in a deeper environment than the area around Hole 627B during the same period. The new dinoflagellate-cyst species Compositosphaeridiuml bahamaensis n. sp., Maghrebinia breviornata n. sp., and Subtilisphaeral habibi n. sp. are described, and Pervosphaeridium truncatum is emended. Additional taxonomic remarks about other species are included.

Eighty-eight samples of Aptian to lower Cenomanian sediments of Sites 545 and 547, DSDP Leg 79, from the Mazagan Plateau area (offshore Northwest Africa) were analyzed for palynomorphs. The very rich dinoflagellate cyst assemblages make it possible to narrow shipboard age determinations and to correlate Sites 545 and 547. The distribution of 174 dinoflagellate cyst taxa is tabulated in this study and the biostratigraphic value of selected dinoflagellate cysts is discussed. Additional taxonomic remarks are made about some species. The new dinoflagellate cyst species Aptea almohadensis, Occisucysta hinzü, O. mazaganensis, and the subspecies Maghrebinia perforata (Clarke and Verdier, 1967) Below, 1981 ssp. mirabilis are described.

Objetivo: Medir la incidencia y determinar los factores de riesgo de las infecciones de transmisión sexual (ITS) en la población del Centro Penitenciario de Daroca (Zaragoza). Método: Estudio de cohortes retrospectivo (2005-2013) para medir la incidencia de ITS y estudio transversal para estudiar los factores de riesgo. Resultados: De los 203 internos, 79 desarrollaron una ITS, 37 tenían ITS previas, el 55,2% conocimientos y el 28,9% comportamientos no favorables a la prevención de ITS. La incidencia fue de 6,5 ITS por cada 1000 internos-año. Las de mayor incidencia fueron la hepatitis B (39,7%), la infección por Ureaplasma urealyticum (19,1%), el herpes simple (16,2%) y la infección por el virus de la inmunodeficiencia humana (8,8%). El riesgo (hazard ratio [HR]) de adquirir una nueva ITS fue significativamente mayor en los internos con antecedentes de ITS previa (HR = 2,61; intervalo de confianza del 95% [IC95%]: 1,01-6,69), y en el límite de la significación para los comportamientos no preventivos (HR = 2,10; IC95%: 0,98-4,53), pero no en los conocimientos frente a ITS (HR = 1,33; IC95%: 0,58-3,07). Conclusión: Los factores de riesgo más relevantes en prisión son los comportamientos y los antecedentes de ITS. Otros factores son ser reincidente, el consumo de drogas inyectadas o estar en un programa de metadona. Los/las profesionales sanitarios y la educación por pares pueden facilitar la prevención y el control.
