Treating women with the drug amodiaquine, either alone or in combination with sulphadoxine-pyrimethamine (SP), was found to almost completely eliminate the malaria parasite and to cause no serious side-effects in the women being treated.
The study, carried out among pregnant women who attended antenatal clinics at a district hospital in Ghana, is published in today's Lancet. The research team was based jointly at St Theresa's Hospital, Nkoranza, Ghana and at LSHTM.
Malaria parasites are becoming increasingly resistant to choloroquine and sulphadoxine-pyrimethamine (SP) across Africa and there is a need to find new drugs which are safe and well tolerated. Most countries in Africa are adopting artesunate-based combination therapy (ACT) as the preferred first line treatment but there is insufficient information as to its safety of ACT during pregnancy. There are concerns that ACT might have a deleterious effect on the developing embryo, particularly when given during the first trimester of pregnancy.
The extent of drug resistance is not as high in west Africa as it is in east Africa, so the authors sought to determine whether amodiaquine, which is effective in some areas with chloroquine resistance, given alone or in combination with SP might be an effective and safe treatment to use until the safety of ACT treatment in pregnancy has been be established.
They screened pregnant women with a gestational age of 16 weeks or more for the malaria parasite and those who tested positive (900 women) were enrolled, and randomly treated with four different regimens. Parasitological failure by day 28 was 14%, 11%, 3% and 0% in the women assigned choloroquine, SP, amodiaquine, and amodiaquine plus SP respectively.
Professor Brian Greenwood, Clinician and Epidemiologist at LSHTM, and one of the study's authors, comments: 'Malaria in pregnancy poses a threat to both the mother and the foetus. Previous studies had already found amodiaquine alone or in combination with SP to be an effective treatment of malaria in children in west Africa, but our research confirms that this is also true for pregnant women. No serious side-effects were noted and the treatment was well tolerated by the majority of women who took part in the trial'.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
