2016, there were more cases and deaths caused by malaria globally than in 2015. An effective vaccine would be an ideal additional tool for reducing malaria's impact. Sanaria((R)) PfSPZ Vaccine, composed [...] (SPZ) has been well tolerated and safe in malaria-naive and experienced adults in the United States and Mali and protective against controlled human malaria infection with Pf in the United States and
The effects and contribution of childhood diseases on the geographical distribution of all-cause under-five mortality in Uganda (Publications)
were obtained from the 2011 Demographic and Health Survey, while data on malaria prevalence were extracted from the 2009 Malaria Indicator Survey. Bayesian geostatistical Weibull proportional hazards models [...] five years in Uganda were attributable to malaria, severe/moderate anaemia, severe/moderate malnutrition and diarrhoea respectively. The attribution of malaria was comparable in Central 2, East-Central [...] used household surveys to quantify the effects and contribution of main...
Our exciting journey to ACT-451840 (Publications)
broadly characterized in vitro as well as in vivo in rat PK experiments as well as two different mouse malaria models. In the P. berghei infected mouse model cure could be achieved at oral doses of 300 mg/kg [...] mg/kg over 3 consecutive days. ACT-451840 was clinically investigated up to an experimental human malaria infection model, where therapeutic effects could be shown.
Identification of a potential antimalarial drug candidate from a series of 2-aminopyrazines by optimization of aqueous solubility and potency across... (Publications)

Cause-specific mortality rates in sub-Saharan Africa and Bangladesh (Publications)
to noncommunicable diseases, and little malaria. HIV dominates in causes of mortality in the South African sites, which contrast with those in highly malaria endemic sites elsewhere in sub-Saharan Africa [...] diseases to mortality in sub-Saharan Africa are lower than has been previously suggested, while malaria is of relatively greater importance. CONCLUSION: The different patterns of mortality we identified
Health facility-based data on women receiving sulphadoxine-pyrimethamine during pregnancy in Tanzania: lessons to learn from a cross-sectional survey... (Publications)
data on women receiving sulphadoxine-pyrimethamine (SP) for intermittent preventive treatment of malaria during pregnancy (IPTp) was carried out at antenatal care clinics in Mkuranga and Mufindi districts [...] system (HMIS) registers, interviews with health-care workers (HWs) and district and national level malaria control program managers corroborated by inter-temporal assessment through observations at HF levels [...] measures are urgently needed to accommodate data on new interventions and...
A large <em>Plasmodium vivax</em> reservoir and little population structure in the South Pacific (Publications)
INTRODUCTION: The importance of Plasmodium vivax in malaria elimination is increasingly being recognized, yet little is known about its population size and population genetic structure in the South Pacific [...] Pacific, an area that is the focus of intensified malaria control. METHODS: We have genotyped 13 microsatellite markers in 295 P. vivax isolates from four geographically distinct sites in Papua New Guinea [...] in sharp contrast to results from regions of low P. vivax endemicity. Prior...
Achieving high coverage of larval-stage mosquito surveillance: challenges for a community-based mosquito control programme in urban Dar es Salaam,... (Publications)
BACKGROUND: Preventing malaria by controlling mosquitoes in their larval stages requires regular sensitive monitoring of vector populations and intervention coverage. The study assessed the effectiveness [...] ess of operational, community-based larval habitat surveillance systems within the Urban Malaria Control Programme (UMCP) in urban Dar es Salaam, Tanzania. METHODS: Cross-sectional surveys were carried [...] particularly low for late-stage Anopheles (2.7%, 3/111), the most direct...
Detection of antibodies to <em>Plasmodium falciparum</em> sporozoites by employing synthetic peptides (Publications)
A new achievement in the immunodiagnosis of malaria has been reached after the knowledge of the molecular structure of some plasmodial antigens has become available. One example is given by the repetitive [...] immunosorbent assay (ELISA) for the detection of antisporozoite antibodies in individuals from malaria-endemic countries. This (NANP)40 ELISA has been employed in a longitudinal study in a rural community [...] and can be useful for monitoring the immune status of populations...
The impact of using primaquine without prior G6PD testing: a case series describing the obstacles to the medical management of haemolysis (Publications)
vivax malaria in glucose-6-phosphate dehydrogenase (G6PD) deficient individuals employs weekly primaquine dosing. This is the only recommended regimen for this patient sub-group. If national malaria programs [...] with unknown G6PD status from two different countries were prescribed primaquine as per national malaria program guidelines. During treatment both patients presented to the clinic with symptoms of anaemia
