I'm at lesson now and I can't try...
...but at your own risk try this:

$getlateste= $DB_site->query("
            SELECT journal_entries.entrytitle,journal_entries.entrydate,
            journal_entries.entry_id,journal_entries.entrytext,
            journal_entries.journal_id,journals.journalist,journals.journalist_id
            FROM ".TABLE_PREFIX."journal_entries AS journal_entries
            LEFT JOIN ".TABLE_PREFIX."journals AS journals ON (journal_entries.journal_id=journals.journal_id)
            GROUP BY journal_entries.journal_id
            WHERE journal_entries.entry_active=1 AND journal_entries.private!=1 AND journals.private!=1
            ORDER BY journal_entries.entrydate DESC
            LIMIT 5
            ");
