Artemisinin combination therapies (ACTs) could be almost as effective in reducing transmission of malaria as insecticide-treated bednets (ITNs) in areas of low transmission, a study based on data from Tanzania has found.
In high transmission areas, long-acting antimalarial regimens may be needed to achieve significant transmission reductions.
Experts from the London School of Hygiene & Tropical Medicine, with colleagues from Imperial College, London (UK) and Radboud Unversity in Nijmegen in the Netherlands used mathematical modelling to predict the potential impact on transmission outcomes of introducing ACT as the first-line treatment for uncomplicated malaria in six areas of Tanzania. The effects of ACT were estimated from clinical trial data. The findings of the study are published today in the journal PLoS Medicine.
The reductions in infection and clinical episodes of malaria were predicted to be highest in areas of low transmission, where it was estimated that a 53% decrease in clinical episodes might occur if all current treatments were switched to ACT. This compared to 21% in the areas with the highest transmission.
Lucy Okell, Research Degree Student at the London School of Hygiene & Tropical Medicine and lead author of the study, commented: 'Overall, we predict that at existing treatment rates, a 100% switch to ACT from non-artemisinin drugs could reduce the rate of clinical episodes of malaria by between 21 and 53% if a short-acting ACT such as artemether-lumefantrine was used.
The impact is smallest in the highest transmission settings, but it could be up to three times greater in these areas if a long-acting ACT regimen was used. As endemic countries gear up for malaria eradication, a target called for by the Bill and Melinda Gates Foundation in 2007, it will be important to know how choice of first-line treatment can help reach this goal’.

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
