    • Using a large cohort of patients from the International Collaboration on Endocarditis Merged Database, we compared coagulase-negative staphylococcal (CoNS) native-valve endocarditis (NVE) to NVE caused by more common pathogens. Rates of heart failure and mortality were similar between patients with CoNS NVE and patients with Staphylococcus aureus NVE, but rates for both groups were significantly higher than rates for patients with NVE due to viridans streptococci. These results emphasize the importance of CoNS as a cause of NVE and the potential for serious complications with this infection.

  • Synchrony in lemming and vole populations in the Canadian Arctic
  • 2002
  • Ingår i: Canadian Journal of Zoology-Revue Canadienne De Zoologie. ; 80:8, s. 1323-1333
  • Tidskriftsartikel (refereegranskat)abstract
    • Population fluctuations may occur in synchrony among several rodent species at a given site, and they may occur in synchrony over large geographical areas. We summarize information on synchrony in lemmings and voles from the Canadian Arctic for the past 20 years. The most detailed available information is from the central Canadian Arctic, where snap-trap samples have been taken annually at several sites for periods of up to 15 years. Geographical synchrony in the same species among different sites was strong, especially for the central and eastern Canadian Arctic. Synchrony among different species at a given site was also generally high. When one species is at high density, densities of all species at that site tend to be high. These results do not easily fit the mobile-predator hypothesis proposed to explain regional synchrony, and are more consistent with the weather hypothesis, which we suggest both entrains synchrony among sites and enforces synchrony among species within a site. We tentatively support the weather hypothesis for geographical synchrony in lemmings, and recommend the establishment of a circumpolar program to monitor lemming cycles and predator movements that would advance our understanding of these large-scale patterns of cyclic synchrony.
