HubMed lets you subscribe to a daily RSS feed for a custom PubMed query...

Let's assume you're already familiar with RSS. Let's also assume that you have a particular research interest, or area of clinical expertise, and need to stay on top of your chosen field.

HubMed describes itself as "an alternative interface to the PubMed medical literature database". Supporting up to 50 citations per day, feeds are generated via a simple search box on the HubMed homepage. The URL of the feed takes the form:

http://www.pmbrowser.info/pmrss.cgi?q=YOUR_TERMS

where YOUR_TERMS corresponds to the PubMed search terms you would like to keep a watch on.

You can use conventional PubMed terms to refine your search. For example:

asthma AND hasabstract

... will find articles on asthma that have an abstract.

"mckenzie b"[au] AND security

... will find articles authored by McKenzie B on security.

"reuter s"[au] AND "J fam plann reprod health care"[ta]

... will find articles by Reuter S and published in The journal of family planning and reproductive health care.

However, you'll run into trouble with improper URL encoding if you try to hand-create your own feed. This will work:

http://www.pmbrowser.info/pmrss.cgi?q=asthma

But this won't:

http://www.pmbrowser.info/pmrss.cgi?q=asthma AND hasabstract

Use the xml button to obtain a correctly-encoded feed URL

To make sure you get the correctly-encoded URL for your feed, click on the xml button in the top right of the search results window (or right-click and copy the link). In the above example, this will be as follows:

http://www.pmbrowser.info/pmatom.cgi?q=asthma%20AND%20hasabstract

Here, %20 encodes the space.
