Preoperative Cognitive Abnormality, Intraoperative Electroencephalogram Suppression, and Postoperative Delirium: A Mediation Analysis.

Background: Postoperative delirium is a common complication that hinders recovery after surgery. Intraoperative electroencephalogram suppression has been linked to postoperative delirium, but it is unknown if this relationship is causal or if electroencephalogram suppression is merely a marker of underlying cognitive abnormalities. The hypothesis of this study was that intraoperative electroencephalogram suppression mediates a nonzero portion of the effect between preoperative abnormal cognition and postoperative delirium.

The relationship between obstructive sleep apnoea and postoperative delirium and pain: an observational study of a surgical cohort.

Patients with obstructive sleep apnoea are at increased risk of adverse postoperative outcomes, such as cardiac and respiratory complications. It has been hypothesised that obstructive sleep apnoea also increases the risk for postoperative delirium and acute postoperative pain. We conducted a retrospective, observational study investigating the relationship of obstructive sleep apnoea with postoperative delirium and acute postoperative pain severity.

Obstructive sleep apnea as an independent predictor of postoperative delirium and pain: protocol for an observational study of a surgical cohort.

: Postoperative delirium and pain are common complications in adults, and are difficult both to prevent and treat. Obstructive sleep apnea (OSA) is prevalent in surgical patients, and has been suggested to be a risk factor for postoperative delirium and pain. OSA also might impact pain perception, and alter pain medication requirements.

[Enthesopathy in inflammatory spondyloarthropathy. Incidence, clinical, radiological and anatomical descriptions. Current status of the question. Apropos of 37 cases].

Based on a series of 37 personal patients and data from the literature, a number of characteristics of enthesopathies can be observed in the course of inflammatory spondyloarthropathies. Our series is based on 20 cases of ankylosing spondylitis (ASP), 8 cases of Fiessinger-Leroy-Reiter syndrome, 8 cases of psoriatic rheumatism (Pso Rh) and one combined form (psoriasis + Reiter + ASP). As well as the frequent involvement of the calcaneus (29 patients), we found more unusual extra-calcaneal localisations in 23 patients.

Delegation of functions by dietitians to dietetic technicians.

Questionnaires were sent to 197 randomly selected hospitals in the continental United States. Replies were used as a basis for determinign the degree to which dietitians are willing to delegate tasks to dietetic technicians. No significant difference was found between the percentage of task functions clinical dietitians were willing to delegate to clinical dietetic techncians and the number that administrative dietitians were willing to delegate to administrative dietetic technicians.
