The 2-phenoxybenzamide 1 from theMedicines for Malaria Venture Malaria Box Project has shown promising multi-stage activity against different strains of P. falciparum. It was successfully synthesized via
The effect of <em>Plasmodium falciparum</em> exposure and maternal anti-circumsporozoite protein antibodies on responses to RTS,S/AS01E vaccination in... (Publications)
BACKGROUND: The RTS,S/AS01(E) malaria vaccine showed lower antibody response and protective efficacy in infants aged 6-12 weeks compared with children aged 5-17 months (for whom this vaccine is recommended) [...] antibody immunoglobulin G (IgG) responses measured by ELISA and pre-vaccination serological markers of malaria exposure by assessing the IgG levels against 1000 P falciparum antigens using partial proteome m [...] The negative effect of maternal anti-CSP IgG in infants did not appear to...
Effect of vitamin A supplementation on morbidity due to <em>Plasmodium falciparum</em> in young children in Papua New Guinea: a randomised trial (Publications)
BACKGROUND: Many individuals at risk of malaria also have micronutrient deficiencies that may hamper protective immunity. Vitamin A is central to normal immune function, and supplementation has been shown [...] morbidity of some infectious diseases. We investigated the effect of vitamin A supplementation on malaria morbidity. METHODS: This randomised double-blind placebo-controlled trial of vitamin A supplementation [...] randomly assigned high-dose vitamin A (n=239) or placebo (n=241), every 3...

quinine+sulfadoxine/pyrimethamine (Q+SP) for malaria in a rural health centre of the East Sepik Province. 179 patients presenting with symptoms and signs of malaria and with Pf (144 patients), Pv (18 patients) [...] provided support for the recent change in the policy for the standard treatment of uncomplicated malaria in PNG from AQ or CQ to the combination of AQ+SP or CQ+SP, a recommendation aimed at slowing down
Resistance of <em>Anopheles stephensi</em> to selected insecticides used for indoor residual spraying and long-lasting insecticidal nets in Ethiopia (Publications)
BACKGROUND: Malaria, transmitted by the bite of infective female Anopheles mosquitoes, remains a global public health problem. The presence of invasive Anopheles stephensi, capable of transmitting Plasmodium [...] 2016. The ecology of this mosquito species differs from that of Anopheles arabiensis, the primary malaria vector in Ethiopia. This study aimed to evaluate the efficacy of selected insecticides, which are [...] are used in indoor residual spraying (IRS) and selected long-lasting...
Long-term acceptability, durability and bio-efficacy of ZeroVector® durable lining for vector control in Papua New Guinea (Publications)
had previously been installed in 40 homes across four study sites representing a cross section of malaria transmission risk and housing style. Structured questionnaires, DL visual inspections and group [...] at 36-months post-installation, the material and fixtures proved durable and the efficacy against malaria vectors did not decrease. However, the DL material had been removed from over 50% of the original [...] suggest DL may not be an appropriate vector control method for large-scale use in...
Assessment of global reporting of adverse drug reactions for anti-malarials, including artemisinin-based combination therapy, to the WHO Programme for... (Publications)
BACKGROUND: In spite of enhanced control efforts, malaria remains a major public health problem causing close to a million deaths annually. With support from several donors, large amounts of artemisinin-based [...] covering the period 1968-2008. All countries in the programme were clustered according to their malaria control phase and income status. The number of individual case safety reports (ICSRs) of anti-malarials [...] ICSRs suspecting anti-malarials were received from 64 countries....
Long-term trends in <em>Anopheles gambiae</em> insecticide resistance in Côte d'Ivoire (Publications)
for ITNs. The rapid rise in insecticide resistance in African malaria vectors has raised alarms about the sustainability of existing malaria control activities. This problem might be particularly acute [...] BackgroundMalaria control is heavily dependent on the use of insecticides that target adult mosquito vectors via insecticide treated nets (ITNs) or indoor residual spraying (IRS). Four classes of insecticide
Comparison of detection methods to estimate asexual <em>Plasmodium falciparum</em> parasite prevalence and gametocyte carriage in a community survey... (Publications)
BACKGROUND: The use of molecular techniques to detect malaria parasites has been advocated to improve the accuracy of parasite prevalence estimates, especially in moderate to low endemic settings. Molecular [...] carefully evaluated. Light microscopy (LM) and rapid diagnostic tests (RDT) are commonly used to detect malaria infection in resource constrained areas, but their limited sensitivity results in underestimation [...] identified by PCR. Thus, LM is not a sufficiently accurate technique...
Local concepts of anemia-related illnesses and public health implications in the Taabo health demographic surveillance system, Côte d'Ivoire (Publications)
newly recruited ones. Malaria und nutritional issues as understood and managed by the population differed from definitions and recommendations provided by the health system. Malaria was not acknowledged [...] which in turn might affect their health status. Local terminology and beliefs about anemia and malaria should be carefully considered when developing health intervention and education programs. The similarity
