Background and Purpose- It has been suggested that statins increase the risk of intracerebral hemorrhage in individuals with a history stroke, which led to precautionary principle avoiding patients prior hemorrhage. However, such prescribing reticence may be unfounded potentially harmful when considering well-established benefits statins. This study is so far largest explore statin-associated stroke.

Summary 1. It is well accepted that fish, if abundant, can have a major impact on the zooplankton community structure during summer, which, particularly in eutrophic lakes, may cascade to phytoplankton and ultimately influence water clarity. Fish predation affects mean size of cladocerans grazing pressure phytoplankton. Little is, however, known about role fish winter. 2. We analysed data from 34 lakes studied for 8–9 years divided into three seasons: autumn/spring winter, four lake classes:...

Abstract Background Mental stress is associated with higher mortality, but it remains controversial whether the association causal or a consequence of physical disease burden in those high mental load. Understanding causality important when developing targeted interventions.
