during the last 12 month (R: 12.5%, NR: 5.6%, p = 0.03). The level of carbon monoxide in expired air is higher in NR (17.6 ppm) that in R (11.9 ppm) (p = 0.01). A similar difference exists between NR (30 [...] (30.7 pp) and R (24.8 ppm) among current smokers (p < 0.01). The main reasons for refusal are lack of time (27.5%), lack of interest for medical study (22.6%), fear of health professionals (18.3%) or the

explained variance was high for the vehicular factor (R2=0.76), moderate for the crustal factor (R2=0.46), and low for the long-range transport factor (R2=0.19). The cross-validation methods suggested that models

is selectively inversely correlated with IFN-gamma and TNF-alpha CD4(+) T cell production (p = 0.02 and p = 0.03) after live M. bovis BCG stimulation. CONCLUSIONS: These results support the hypothesis that [...] patients with active TB and DM compared to patients with active TB only after live M. bovis BCG (p = 0.04) but not after Mtb peptide pools re-stimulation. Irrespective of TB status, level of glycaemia is

Conclusions: Frequent VL monitoring and [...] = 61) was selected. Results: We found that 50.8% of individuals in the SHCS, 72.5% in Uganda and 81.0% in Lesotho harboured HIV with high-level resistance to at least two drugs from their current regimen
