Prevalence of malaria across Papua New Guinea after initial roll-out of insecticide-treated mosquito nets (Publications)
average of 12.1% (95% CI 9.5, 15.3) in the national sample. More people were infected with Plasmodium falciparum (7.0%; 95% CI 5.4, 9.1) than with P. vivax (3.8%; 95% CI 2.4, 5.7) or P. malariae (0.3%; 95% [...] 95% CI 0.1, 0.6). Parasitaemia was strongly age-dependent with a P. falciparum peak at age 5-9 years and a P. vivax peak at age 1-4 years, yet with differences between geographical regions. Individual

At 3 years, the cumulative incidence of death and LTFU were 12.5% (11.5%-13.5%) and 25.4% (24.0%-26.9%), respectively, with important differences between countries as follows: [...] and World Health Organization stage at start of ART are reported. RESULTS: Among 7725 patients, 449 (5.8%) did not return after initiation of ART. During 9575 person-years, 698 (9.6%) of those with at least

The appearance during treatment of febrile reactions (RR 11.5), headache (RR 2.5), bullous eruptions (RR 4.5) and systolic hypotension (RR 2.6) were associated with an increased risk for [...] excluded from the analysis. The overall rate of encephalopathic syndromes in the cases analysed (n=34) was 5.8%, of which 38.2% died. We did not find any parameters of predictive value for the risk of developing
Pharmacology of DB844, an orally active aza analogue of pafuramidine, in a monkey model of second stage human African trypanosomiasis (Publications)
during the 300 days of post treatment monitoring, resulting in a cure rate of 3/8 (37.5%) and 3/7 (42.9%) for the 5 mg/kg×10 days and the 6 mg/kg×14 days dose regimens respectively. These DB844 efficacy [...] nervous system (CNS).

CONCLUSIONS: Simultaneous carbimazole reduces [...] Radioiodine target doses between 33 and 839 Gy were applied. Overall, the euthyroidism rates were 16.5% and 64.8%, while the hypothyroidism rates were 37.6% and 14.8% in Graves' disease and toxic nodular [...] goitre, respectively.
