Functional interrelationship of brain aging and delirium.

Theories on the development of delirium are complementary rather than competing and they may relate to each other. Here, we highlight that similar alterations in functional brain connectivity underlie both the observed age-related deficits and episodes of delirium. The default mode network (DMN) is a group of brain regions showing a greater level of activity at rest than during attention-based tasks.

[Prognostic significance of skeletal lesions in multiple myeloma].

Prognostic significance of the skeletal lesions in multiple myeloma. Fifty-two patients with multiple myeloma have been analysed and relations between bone X-ray changes and several clinical biohumoral parameters and survival have been found. Our studies show no correlation between the extent of skeletal lesions and the seriousness of anaemia, or between bone marrow infiltration and renal involvement.
