You simply add the second loop within the first.

Here's an example:

<?php

$topic = mgd_list_topics(354);

if ($topic) {

  for ($i = 0; $i < 25 && $topic->fetch(); $i++) {

    /* We're inside the topic listing for loop now */

    ?>
      <strong>&(topic.name);</strong><br>
    <?php

    $article = mgd_list_topic_articles($topic->id);

    if ($article) {

      /* I'm using 'while' here but a 'for' loop
        would work as well */

      while ($article->fetch()) {

        ?>

          &(article.title);<br>
          &(article.abstract);<br>

        <?php

      }

    }

  }

}
?>

Hopefully this helps.
