They are just using the built-in vB external script with some javascript coding to spit it out:

<script src="http://www.healthdiscovery.net/forums/external.php?type=js" type="text/javascript"></script>
                      <script type="text/javascript">
<!--
for (i = 0; i < 7; i++)
{
document.writeln("<a href=\"http://www.healthdiscovery.net/forums/showthread.php?threadid="+threads[i].threadid+"\">•&nbsp;"+threads[i].title+"<br></a>Poster:("+threads[i].poster+")<br />");
}
//-->
</script>

Cheers,
