Japanese encephalitis risk and contextual risk factors in southwest China: a Bayesian hierarchical spatial and spatiotemporal analysis.

It is valuable to study the spatiotemporal pattern of Japanese encephalitis (JE) and its association with the contextual risk factors in southwest China, which is the most endemic area in China. Using data from 2004 to 2009, we applied GISmapping and spatial autocorrelation analysis to analyze reported incidence data of JE in 438 counties in southwest China, finding that JE cases were not randomly distributed, and a Bayesian hierarchical spatiotemporal model identified the east part of southwest China as a high risk area. Meanwhile, the Bayesian hierarchical spatial model in 2006 demonstrated a statistically significant association between JE and the agricultural and climatic variables, including the proportion of rural population, the pig-to-human ratio, the monthly precipitation and the monthly mean minimum and maximum temperatures.

[Procalcitonin as a predictor of trauma severity and post-traumatic sepsis in children].

Objective: To determine the association of procalcitonin (PCT) with trauma severity and post traumatic sepsis in children.

Methods: The blood samples of 30 children with acute trauma in a Pediatric unit were collected for four consecutive days. The levels of PCT, IL-6, CRP and WBC were measured.
