<div id="trends">
<?php
  $trends_posts = get_posts(array(
    'tag_slug__in' => array( 'trends' ),
    'posts_per_page' => 1
  ));
  
  if ( count( $trends_posts ) == 1 ) :
    
    $org_post = $GLOBALS['post'];
  
    $GLOBALS['post'] = $trends_posts[0];
    setup_postdata( $GLOBALS['post'] );
?>
  
  <h3><?php the_title(); ?></h3>

    <?php the_excerpt(); ?>

<?php
    $GLOBALS['post'] = $org_post;
    setup_postdata( $GLOBALS['post'] );
