Analogy tests and psychopathology at follow-up after open heart surgery.

A study of 100 coronary bypass and cardiac valvular surgery patients investigated whether preoperative brain damage, as measured by the Conceptual Level Analogy Test (CLAT), is a major risk factor for postoperative psychiatric symptoms and mortality. Three cognitive psychological tests, including the CLAT, and psychatric interviews were given preoperatively, postoperatively, and at 18-month follow-up. Surgical outcome was specified as: Catastrophic Outcome (death or severe stroke), Psychiatric Complications, or Good Outcome (survival with no psychiatric complications). Inhospital outcome related significantly to analogy test scores, as did both surgical procedure and diagnosis of rheumatic heart disease. However, long-term outcome was unrelated to medical diagnosis and only weakly related to surgical procedure, but highly significantly related to preoperative analogy scores. The CLAT was a more consistent predictor of both short- and long-term outcome than any of the other ten variables considered (medical and surgical variables, inhospital outcome, demographic measures, other psychological tests).

Inhibition of Bacillus megaterium by a trimethylamine oxide-associated browning reaction product.

Heated combinations of trimethylamine oxide (TMAO) and culture media (tryptone, glucose, yeast extract broth or a defined minimal medium), or heated TMAO and glucose, contained substance(s) that inhibited growth of Bacillus megaterium. Inhibition was expressed primarily as an increase of the lag phase of growth; the logarithmic growth rate was comparable to control cultures. The addition of unheated TMAO to the culture media had no effect on growth. Results suggested that TMAO was decomposed during heating and that dimethylamine, one of the degradation products, reacted with glucose by a Maillard-Amadori reaction to produce the inhibitory substance(s).
