increasing temporal

  • Moreover, if associations between environmental factors and the disease exist, it is relevant to establish whether increasing temporal trends are occurring cross-sectionally, affecting all age-groups at the same point in time (period effects), or longitudinally, affecting all age-groups from the same birth cohort (cohort effects) ( 16 ). (


  • For high-complexity data sets, hierarchical cluster methods need a more strict dissimilarity threshold to define OTUs because the commonly used dissimilarity threshold of 3% often leads to an under-estimation of the number of OTUs. (
  • In general, hierarchical clustering methods perform better at lower dissimilarity thresholds. (


  • The present study allows us to conclude that the disease was clustered in the Southwest side of the city in 2006, suggesting that this area may require special attention with regard to control and prevention measures. (


  • I have a special interest in methods and analysis of clustering of chronic diseases. (
  • Although a number of methods have been developed and commonly used to cluster the sequences into OTUs, relatively little guidance is available on their relative performance and the choice of key parameters for each method. (

  • A space-time analysis of American visceral leishmaniasis (AVL) in humans in the city of Bauru, São Paulo State, Brazil was carried out based on 239 cases diagnosed between June 2003 and October 2008. (
  • The problem became even further complex at the level of populations or communities, including parasites, vectors, reservoirs, and hosts (among them humans) distributed dynamically in space and time in a matrix of changing environment [ 14 - 16 ]. (


  • Two clusters of cases occurred: an introduced P. vivax outbreak associated with Anopheles aquasalis in 1990-1991, and an autochtonous focus of P. malariae associated with An. (
  • Application of a space-time statistic showed a significant clustering of P. malariae cases, and, to a lesser extent of P. vivax cases, but not of P. falciparum cases. (
  • Seasonality and clustering of Kawasaki syndrome cases were studied in Japanese children with Kawasaki syndrome reported in nationwide surveys in Japan. (
  • To assess clustering, we compared the number of cases per day (daily incidence) with a simulated distribution (Monte Carlo analysis). (
  • Temporal clustering of Kawasaki syndrome cases was detected with nationwide outbreaks. (
  • Temporal clustering of cases combined with marked seasonality suggests an environmental trigger for this clinical syndrome. (
  • Clear documentation of seasonality and clustering of Kawasaki syndrome cases would lend further weight to the hypothesis that Kawasaki syndrome has an environmental trigger. (


  • This finding was confirmed by the time series analysis, which also showed a positive tendency over the period analyzed. (
  • Age-period-cohort analysis shows that the variation over time has a linear component that cannot be ascribed to either the calendar period or the birth cohort. (


  • Multilevel (random intercept) Poisson regression models were used to model the effects of sex, age, calendar time, and birth cohorts on temporal trends, taking into account the registry-level variance component. (
  • Two examples of new primitives are near real-time charged particle direction or charge clusters without pixel boundary effects. (


  • One of the proposed solutions for a pT based trigger at SLHC for CMS is based on the concept known as the "cluster width" approach, in which clusters produced by low pT tracks are rejected based on the width of the cluster shape, made either on a single strip sensor or a doublet of strip sensors by a suitable electronics logic at the level of the front-end. (


  • The results on ecoepidemiology of leishmaniasis in Argentina related to climate variables at different scales of space and time are presented. (


  • PLOS ONE promises fair, rigorous peer review, broad scope, and wide readership - a perfect fit for your research every time. (


  • Despite noted difficulties, discussion section deals with many attempts which were made for leishmaniases in different time and space scales. (



  • Among nestling House Sparrows, FM virus infections were clustered in time and space. (
