Short-course combination treatment for experimental chronic Chagas disease.

Chagas disease, caused by the protozoan parasite , affects millions of people in the Americas and across the world, leading to considerable morbidity and mortality. Current treatment options, benznidazole (BNZ) and nifurtimox, offer limited efficacy and often lead to adverse side effects because of long treatment durations. Better treatment options are therefore urgently required.

Structure-Guided Design and Synthesis of a Pyridazinone Series of Proteasome Inhibitors.

There is an urgent need for new treatments for Chagas disease, a parasitic infection which mostly impacts South and Central America. We previously reported on the discovery of GSK3494245/DDD01305143, a preclinical candidate for visceral leishmaniasis which acted through inhibition of the proteasome. A related analogue, active against , showed suboptimal efficacy in an animal model of Chagas disease, so alternative proteasome inhibitors were investigated.

Are healthcare workers' intentions to vaccinate related to their knowledge, beliefs and attitudes? A systematic review.

Background: The Summit of Independent European Vaccination Experts (SIEVE) recommended in 2007 that efforts be made to improve healthcare workers' knowledge and beliefs about vaccines, and their attitudes towards them, to increase vaccination coverage. The aim of the study was to compile and analyze the areas of disagreement in the existing evidence about the relationship between healthcare workers' knowledge, beliefs and attitudes about vaccines and their intentions to vaccinate the populations they serve.

Methods: We conducted a systematic search in four electronic databases for studies published in any of seven different languages between February 1998 and June 2009.
