[Statin treatment as primary prevention in dyslipidaemic patients older than 75 years].

Objectives: To determine possible differences in the incidence of cardiovascular events between dyslipidaemia patients older than 75 years treated with statins compared to those not treated with them, as primary prevention.

Material And Methods: A retrospective cohort study was conducted in patients older than 75 years with dyslipidaemia in a health centre, between 2005 and 2015. The study included 329 patients (182 on treatment with statins and 147 with no lipid-lowering treatment) who met the inclusion criteria (patients older than 75 years, on treatment with statins for at least 3 years, or to have not had any lipid lowering treatment and as primary prevention).

Human amniotic membrane intra-articular injection prevents cartilage damage in an osteoarthritis model.

Osteoarthritis (OA) is a degenerative joint disease that affects the soft tissues and bones of involved articulations as a result of deregulation between synthesis and extracellular matrix degradation in articular cartilage. The present study evaluated the effect of intra-articular injection of human amniotic membrane (AM) as a treatment in an OA animal model in the knee. Chemical OA was developed in the knees of New Zealand rabbits.

Early origin of parental care in Mesozoic carrion beetles.

The reconstruction and timing of the early stages of social evolution, such as parental care, in the fossil record is a challenge, as these behaviors often do not leave concrete traces. One of the intensely investigated examples of modern parental care are the modern burying beetles (Silphidae: Nicrophorus), a lineage that includes notable endangered species. Here we report diverse transitional silphids from the Mesozoic of China and Myanmar that provide insights into the origins of parental care.

New and revised maimetshid wasps from Cretaceous ambers (Hymenoptera, Maimetshidae).

New material of the wasp family Maimetshidae (Apocrita) is presented from four Cretaceous amber deposits - the Neocomian of Lebanon, the Early Albian of Spain, the latest Albian/earliest Cenomanian of France, and the Campanian of Canada. The new record from Canadian Cretaceous amber extends the temporal and paleogeographical range of the family. New material from France is assignable to Guyotemaimetsha enigmatica Perrichot et al.
