ReviewImplications of recent accumulating knowledge about endothelial glycocalyx on anesthetic management.
The endothelial glycocalyx is a labile, fine structure coating the luminal membrane of intact healthy vascular endothelium. For many decades, no physiologic importance was linked to this structure. It is crucial for vascular barrier function. ⋯ Perioperative damage of the glycocalyx has been demonstrated, and is linked with morbidity and even mortality in surgical patients. Research on the glycocalyx should change many of the current perioperative management guidelines, and focusing on its protection is plausible. The present article reviews what we already know about the glycocalyx and how this knowledge has changed anesthesiologist perspectives.

The aim of this study was to determine the ability of the central sensitization inventory (CSI), a new screening instrument, to assist clinicians in identifying patients with central sensitivity syndromes (CSSs). ⋯ The CSI is a useful and valid instrument for screening patients for the possibility of a CSS, although the chances of false positives are relatively high when evaluating patients with complex pain and psychophysiological disorders.

Comparative StudyOur paper 20 years later: 1-year survival and 6-month quality of life after intensive care.
In the early 1990s, the in-hospital mortality rate of intensive care unit (ICU) patients dropped, and interest in the quality of life (QOL) of ICU survivors increased. In 1996, we published a study to investigate 1-year survival after hospital discharge and 6-month QOL after intensive care. Now, we compare our previous results with those reported in the recent literature to appraise any changes, and new knowledge in the area. ⋯ Differences between studies on long-term survival and QOL do not allow conclusions to be drawn about change over time. No change was found in neuropsychological morbidities. However, a lack of change may not be viewed negatively, because critically ill patients who survive ICU today may be at higher risk for poor long-term outcome than in the past due to the higher severity of their illness and the more aggressive treatments received. Future studies may provide understanding of the relationships between psychiatric symptoms, cognitive impairment, functional disability, and QOL.

Patients with spinal stenosis with concomitant degenerative spondylolisthesis (DS) and predominant back pain (PBP) have been shown to have inferior outcome after surgery. Studies comparing outcome according to preoperative pain predominance and treatment received are lacking. ⋯ Patients with PBP operated with DF report better outcomes in terms of pain, function, and health-related quality of life than patients with D. Although these differences are significant on a group level, they may fail to reach minimal clinical significant difference. Patients with PLP report significantly more improvement in terms of BP with DF compared with D, but because of baseline differences in preoperative BP, these improvements may not be explained by the added fusion per se. At the 2-year follow-up, no significant differences were observed between the D and DF patients in either the PBP or PLP groups, but greater loss to follow-up in the DF groups could potentially bias these findings.

Haloperidol Suppresses Murine Dendritic Cell Maturation and Priming of the T Helper 1-Type Immune Response.
Haloperidol has immunomodulatory effects when used to treat patients with schizophrenia and also is used to sedate critically ill patients in the intensive care unit. Although the mechanism by which haloperidol affects immune function is unclear, one possibility is that it alters dendritic cell (DC) function. DCs are potent antigen-presenting cells that influence the activation and maturation of T lymphocytes. In this study, we investigated the in vitro and in vivo immunomodulatory effects of haloperidol on DC-mediated immune responses. ⋯ The results of our study suggest that haloperidol suppresses the functional maturation of DCs and plays an important role in the inhibition of DC-induced T helper 1 immune responses in the whole animal. Furthermore, the effect of haloperidol on DCs may be mediated by dopamine D2-like receptors. Together, these results demonstrate that administration of haloperidol suppresses DC-mediated immune responses.
