Community and clinic-based HIV-1 control programme fails to decrease incidence of HIV-1 in Zimbabwe

27.03.2007
A trial in Zimbabwe has shown that a programme of integrated peer education, condom distribution, and management of sexually transmitted infections did not reduce the overall incidence of HIV-1.

The study, published in PLoS Medicine, by Simon Gregson and colleagues from Imperial College London, randomised different communities in eastern Zimbabwe over a 3 year period. Six pairs of communities in Eastern Zimbabwe were compared, each of which had its own health center.

Control communities received the standard government services for preventing HIV. The other communities received a package of additional strategies including education and condom distribution amongst sex workers and their clients; better services at sexually transmitted infection clinics; and educational HIV/AIDS open days at health centers.

This was a large trial with more than 63,000 meetings being conducted and 7 million condoms distributed by trained peer educators. The researchers found that although male participants benefit ed from the programme with a decrease in incidence of HIV-1, a reduction in reporting of unprotected sex with casual partners, and a decrease in symptoms of sexually transmitted infections, overall there was no change in any of these outcomes for the population at large including the incidence of HIV-1 among the population in general - the main outcome of the trial.

These results are disappointing given the urgent need for control measures for HIV-1 in sub-Saharan Africa. The authors conclude that they “emphasise the need for alternative strategies of behaviour-change promotion.”

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...
