There are have been intermittent problems with emailing results from all ProQuest databases, including Pharmaceutical News Index and other news sources, e.g. ABI/Inform and ProQuest Health & Medical Complete. ProQuest is treating this as an urgent problem, and working on a solution.
In the meantime, please save results as a file, and then email the file, or print your results immediately rather than emailing. We will post another announcement when the problem is resolved.
