Challenges of DHS and MIS to capture the entire pattern of malaria parasite risk and intervention effects in countries with different ecological... (Publications)
multiple indicator cluster survey. Malaria parasitological data were collected, but the survey period did not overlap with the high malaria transmission season. A malaria indicator survey (MIS) was also conducted [...] conducted during the same year, within the malaria peak transmission season. This study compares estimates of the geographical distribution of malaria parasite risk and of the effects of interventions [...] used to identify the most important climatic predictors and indicators of ...
Infant and child mortality in relation to malaria transmission in KEMRI/CDC HDSS, Western Kenya: validation of verbal autopsy (Publications)
(VA) is widely used for estimating malaria specific mortality rates, but does not reliably distinguish malaria from other febrile illnesses. Overall malaria attributable mortality includes both direct and [...] both all-cause and malaria-specific mortality. 48.2% of the deaths could be attributed to malaria by analysing the exposure-response relationship, though only 20.5% of VAs assigned malaria as the cause and [...] BACKGROUND: Malaria transmission reduction is a goal of many malaria control...
A public antibody lineage that potently inhibits malaria infection through dual binding to the circumsporozoite protein (Publications)
with attenuated Plasmodium falciparum sporozoites (PfSPZs) has been shown to be protective against malaria, but the features of the antibody response induced by this treatment remain unclear. To investigate [...] repeated injection of Sanaria PfSPZ Vaccine and who were found to be protected from controlled human malaria infection with infectious homologous PfSPZs. All isolated IgG monoclonal antibodies bound to P.
Global action for training in malaria elimination [Commentary] (Publications)
The Rethinking Malaria Leadership Forum, held at Harvard Business School in February 2017 with collaboration of the Barcelona Institute for Global Health and the Swiss Tropical and Public Health Institute [...] training gap as a high priority for both analysis and action. The gap in human resource training for malaria elimination needs to be addressed in order to assure continued progress. This paper identifies major [...] assist in filling the training gaps, and proposes global actions to...
Hemozoin-catalyzed precipitation polymerization as an assay for malaria diagnosis (Publications)
Methods to diagnose malaria are of paramount interest to eradicate the disease. Current methods have severe limitations, as they are either costly or not sensitive enough to detect low levels of parasitemia [...] increase is proportional to the concentration of hemozoin, with a detection limit of 0.85 ng mL(-1). Malaria parasites in human blood can be detected down to 10 infected red blood cells muL(-1). The assay could
High cure rates and tolerability of artesunate-amodiaquine and dihydroartemisinin-piperaquine for the treatment of uncomplicated falciparum malaria in... (Publications)
BACKGROUND: The Tanzanian National Malaria Control Programme (NMCP) and its partners have been implementing regular therapeutic efficacy studies (TES) to monitor the performance of different drugs used [...] mefantrine, which is the first-line anti-malarial for the treatment of uncomplicated falciparum malaria. Data on the performance of other artemisinin-based combinations is urgently needed to support timely [...] parasitological responses of ASAQ and DP for directly observed treatment of...
Insufficient sensitivity of laser desorption-time of flight mass spectrometry-based detection of hemozoin for malaria screening (Publications)
detection of hemozoin was assessed for its performance characteristics as a rapid screening test for malaria. In spite of good specificity of > 95%, poor sensitivity of 80.2% for microscopically positive samples
Lysyl-tRNA synthetase as a drug target in malaria and cryptosporidiosis (Publications)
Malaria and cryptosporidiosis, caused by apicomplexan parasites, remain major drivers of global child mortality. New drugs for the treatment of malaria and cryptosporidiosis, in particular, are of high [...] PfKRS1 and C. parvum KRS (CpKRS). In vivo proof of concept was established in an SCID mouse model of malaria, after oral administration (ED90 = 1.5 mg/kg, once a day for 4 d). Furthermore, we successfully [...] HsKRS. Our work validates apicomplexan KRSs as promising targets for the...
Highly heterogeneous residual malaria risk in western Thailand (Publications)
substantial and poses a challenge for the national malaria elimination program. To determine epidemiological parameters as well as risk factors for malaria infection in western Thailand, we carried out a [...] Over the past decades, the malaria burden in Thailand has substantially declined. Most infections now originate from the national border regions. In these areas, the prevalence of asymptomatic infections [...] provinces on the Thailand-Myanmar border. Blood samples from 999 local...
