Bluetongue in Belgium: episode II.
data were analysed. Overall cumulative incidence at herd level was estimated at 11.5 (11.2-11.8) and 7.5 (7.3-7.8) per cent in cattle and sheep populations respectively. The findings went in favour of ...
The gap between food-based dietary guidelines and usual food consumption in Belgium, 2004.
was collected with two non-consecutive 24 h recalls, using the validated software package EPIC- SOFT in combination with a self-administered FFQ. Habitual food intake was estimated by the Nusser method. ...
Description of cervical cancer mortality in Belgium using Bayesian age-period-cohort models.
In the Netherlands, the proportion of not-otherwise specified uterine cancer deaths was small over large periods and therefore internal reallocation could be used to estimate the corrected rates ...
Marginal structural models for partial exposure regimes.
the informative censoring of the survival time by hospital discharge and the instability of the inverse weighting estimation procedure. We accommodate this by introducing a new class of marginal ...
Trends in social inequalities in obesity: Belgium, 1997 to 2004.
METHODS: We used data from three national cross-sectional health interview surveys (1997 n=7953, 2001 n=8887, and 2004 n=9709) to estimate age-standardized obesity prevalence and a series of summary measures ...
Prevaccination distribution of human papillomavirus types in women attending at cervical cancer screening in Belgium.
higher in cytologically negative women but similar in women with cervical lesions. These differences could be due to the use of a PCR with high analytic sensitivity. These data are relevant for estimating ...
National influences on catheter-associated bloodstream infection rates: practices among national surveillance networks participating in the European HELICS project.
CI: 1.02-4.25) were independent risk factors for high CVC- BSI rates. Substantial variation existed in CVC- BSI prevention activities, surveillance methods and estimated CVC- BSI rates among the ...
Transplacental infection and apparently immunotolerance induced by a wild-type bluetongue virus serotype 8 natural infection.
BT, born during the vector-free period, 11% were found to be RT-qPCR positive. The true prevalence was estimated to be 2.3%, indicating the extent of transplacental infection in a group of 733 calves of ...
Establishing the spread of bluetongue virus at the end of the 2006 epidemic in Belgium.
study was to provide unbiased estimates of BT-seroprevalence for different regions of Belgium. Since under-reporting was suspected during the epidemic, a second goal was to compare the final dispersion of ...
A Bayesian evaluation of six diagnostic tests for foot-and-mouth disease for vaccinated and non-vaccinated cattle.
estimated sensitivity of 94% (95% CI from 89.8 to 98.1%). Second best for vaccinated cattle were two tests with estimated sensitivities of 85% (95% CI from 78.9 to 89.7%) and 92% (95% CI from 86.2 to 95.6%). ...
