On the other hand, no unequivocal support was found for the assumption that syringe exchange programs help reduce HIV and hepatitis infections among injecting abusers. Nor does low coverage of needles and syringes via syringe exchange programs seem to lead to greater risk of infection. This is shown in a dissertation from Mid Sweden University.
"Syringe exchange is used by various categories of abusers, and the patterns of use vary greatly. This concerns how long they participate, how often they make their visits, and what services they request," says Nils Stenström. One surprising finding was that a large proportion of the visitors, nearly half, visited the clinic without exchanging syringes. These visits are social in nature - nevertheless they are connected with reduced risks of infection. This shows that the associations between syringe exchange, risk behaviour, and infection risks are complex, according to Stenström.
The studied followed 3,660 injecting abusers taking part in the syringe exchange program in Malmö, Sweden, over a 15 year period. Nearly 180,000 visits served as the basis for comprehensive analysis of how the program is used and developments regarding contagion, HIV and hepatitis testing, vaccinations, and social development. The study is probably the largest ever undertaken in the world of the long-term effects of a syringe exchange program.
Analyses of the visits data reveal that the longer individuals participate in the program, the more often they visit the clinic. But the hope that syringe exchange would constitute a springboard to regular public care and treatment options for drug abusers was not realized to any great extent. On the other hand, the clinic itself, through extensive testing, vaccination, and counseling, did take on an important role in general preventive health efforts.
The title of the dissertation is Syringe exchange for injecting drug users - A longitudinal study of participants in a syringe exchange programme in Malmö, Sweden.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
