Delirium in the ICU can compromise the recovery process, prolong ICU and hospital stay and increase mortality. Therefore, recognition of delirium is of utmost importance. ⋯ In the Netherlands, delirium is considered an important problem in the ICU, although its incidence is estimated to be low by the ICU team. The diagnosis of delirium is most frequently established by a geriatrician or psychiatrist after consultation, while diagnostic instruments are infrequently used. Efforts should be undertaken to implement delirium protocols and a routinely applied diagnostic instrument in the ICU.

Targeting the CD20 antigen on B lymphocytes with the monoclonal antibody rituximab has greatly improved the outcome of patients with B-cell malignancies. Despite the success of rituximab, resistance occurs in about half of the patients, resulting in non-response to treatment or early relapse of the original disease. A better understanding of the mechanism of rituximab resistance has lead to the development of novel, improved anti-CD20 antibodies. This review describes the development of CD20-targeted therapy from its historical background towards the next generation of anti-CD20 monoclonal antibodies and explains new strategies to overcome resistance.
