background bacterial resistance to antibiotics has become a major source of concern for public health. pseudomonas aeruginosa strains are important opportunistic pathogens. these bacteria have a high resistance to a wide range of existing antimicrobials and antibiotics. objectives the present study was performed to evaluate the frequency of kpc in p. aeruginosa isolated from clinical samples of...

Cohort studies can be biased by unmeasured confounding. We propose a hybrid ecologic-epidemiologic design called the trend-in-trend design, which requires a strong time trend in exposure, but is unbiased unless there are unmeasured factors affecting outcome for which there are time trends in prevalence that are correlated with time trends in exposure across strata with different exposure trends...

A four stage social network trend mining framework, the IGCV (Identification, Grouping, Clustering and Visualisation) framework, is described. The framework extracts trends from social network data and then applies a sequence of techniques (“tools”) to this data to facilitate interpretation of the identified trends. Of particular note is the visualisation of trend migrations (changes) that feat...

Average age and size at maturation have decreased in many commercially exploited fish stocks during the last decades. This phenomenon could be either a direct phenotypic response to some environmental variation, or the evolutionary consequence of some selective pressure. Traditionally used maturation indices, i.e. the age and size at which 50% of individuals are mature, are not appropriate to a...

Numerous environmental factors have been identified as influential in the development of schizophrenia. Some are byproducts of modern life, yet others were present in our evolutionary past and persist to a lesser degree in the current era. The present study brings together published epidemiological data for schizophrenia and data on variables related to photic input for places of residence acro...
