Link between maternal malaria, pregnancy history, and infant risk

08.11.2005


Every year at least 30 million women in malaria-endemic areas of Africa become pregnant. Many of them develop placental malaria, a pregnancy-specific form of the disease, which frequently results in low birth weight of the child. Placental malaria might increase the susceptibility of infants to malaria, but previous studies were inconclusive. A careful study by Patrick Duffy and colleagues (of the Seattle Biomedical Institute), published in the international open-access medical journal PLoS Medicine, found that placental malaria does raise the risk of malaria in infants. The researchers also discovered a surprising protective effect against malaria in first-time mothers, regardless of whether they had placental malaria.



Duffy and colleagues studied a total of 453 infants, of which 69 were born to mothers with placental malaria. Of those 69, 31 were born to first-time mothers, and 38 to mothers who had given birth before. They then followed those infants for a year and checked whether during that time they became sick with malaria. There were two major findings. First, the researchers found that overall children whose mothers had placental malaria were more likely to get sick with the disease themselves. Second, they found something surprising about the birth order of the infants, namely that children from first time mothers were less likely to develop malaria, regardless of whether their mother had placental malaria.

These results suggest that both the number of previous pregnancies and placental malaria affect an infant’s chances of developing malaria. It might be that in first-time mothers placental malaria stimulates the mother’s immune system and this somehow protects the baby against malaria. These provocative results will prompt further studies of the effects of malaria during pregnancy. If confirmed, the results here suggest that reducing placental malaria specifically in women who had previously given birth would have the most effect.

Im Focus: Powerful IT security for the car of the future – research alliance develops new approaches

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.

Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

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...

Im Focus: LZH showcases laser material processing of tomorrow at the LASYS 2018

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

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...

Im Focus: Self-illuminating pixels for a new display generation

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...
