BACKGROUND Little is known about the effect of meteorological conditions and geographical location on bacterial colonization rates particularly of antibiotic-resistant Gram-positive bacteria. We aimed to evaluate the effect of season, meteorological factors, and geographic location on methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE) colonization. M...

In temperate coastal zones, episodic meteorological forcing can have a strong impact on the classical seasonal phytoplankton succession. Episodes of continental runoff and wind storms involve nutrient enrichment and turbulence, 2 factors that can promote primary production and alter the planktonic community species composition and size structure. We determined the joint influence of these 2 var...

OBJECTIVES The aim of this study was to identify meteorological factors that could be associated with an increased risk of community-acquired Legionnaires' disease (LD) in two Swiss regions. DESIGN Retrospective epidemiological study using discriminant analysis and multivariable Poisson regression. SETTING We analysed legionellosis cases notified between January 2003 and December 2007 and w...

Reactive oxygen species can be produced in leaf cells during normal aerobic metabolism or in a variety of exogenous factors, which may cause oxidative damage to plants, unless they have an efficient antioxidant defense system, consisting of enzymatic and non-enzymatic substances. This work raised the hypothesis that plants of Ipomoea nil cv. Scarlet O'Hara, a native species and ornamental vine ...

BACKGROUND The effects of climate variations on bacillary dysentery incidence have gained more recent concern. However, the multi-collinearity among meteorological factors affects the accuracy of correlation with bacillary dysentery incidence. METHODS As a remedy, a modified method to combine ridge regression and hierarchical cluster analysis was proposed for investigating the effects of clim...

The increasing trend in ground ozone (O3) concentration has recently been recognized in Japan, though concentrations of ozone precursors have been decreased. It is well known the status of atmospheric has been changing on a long term, not only over the world, but also in Japan. Therefore, one of causes is possibly imagined that is the effect of meteorological conditions. In order to confirm whe...

Global warming will unquestionably increase the impact of heat on individuals who work in already hot workplaces in hot climate areas. The increasing prevalence of this environmental health risk requires the improvement of assessment methods linked to meteorological data. Such new methods will help to reveal the size of the problem and design appropriate interventions at individual, workplace a...

The ability of many animals to access and exploit food is dependent on the ability to move. In the case of scavenging birds, which use soaring flight to locate and exploit ephemeral resources, the cost and speed of movement vary with meteorological factors. These factors are likely to modify the nature of interspecific interactions, as well as individual movement capacity, although the former a...

Pulmonary embolism is a frequent condition, related with high mortality. Frequency of pulmonary embolism episodes has been related with several meteorological factors. The aim of the study was to analyze the influence of meteorological factors on the occurrence of pulmonary embolism in male and female patients. Medical data of patients hospitalized at our institution in 2007-2008 was analyzed. ...

Bacillary dysentery remains a public health concern in the world. Hunan Province is one of the provinces having the highest risk of bacillary dysentery in China, however, the spatial-temporal distribution, variation of bacillary dysentery and sensitivity to meteorological factors in there are unclear. In this paper, a Bayesian space-time hierarchical model (BSTHM) was used to detect space-time ...
