<p>Numerous main index entries and cross references were modified to reflect changes in the MeSH vocabulary.</p>
<p>For example:
</p>
<ul>
<li><em>Consumer Satisfaction</em> was deleted as a main heading and made a cross reference to <em>Consumer Behavior</em>.</li>
<li><em>Food, Supplemented</em>, formerly a cross reference to <em>Dietary Supplements</em>, is now a cross reference to <em>Food, Fortified</em>.</li>
<li><em>Adolescent Psychology</em> was changed to <em>Psychology, Adolescent</em>.</li>
<li><em>Toxicokinetics</em>, formerly a cross reference to <em>Pharmacokinetics</em>, is now a main index heading.</li>
</ul>
