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.

A Qualitative Study Exploring Moral Distress in the ICU Team: The Importance of Unit Functionality and Intrateam Dynamics.
Our study objectives were to determine the key sources of moral distress in diverse critical care professionals and how they manage it in the context of team-based models. ⋯ This study identified the ways in which moral distress manifests across critical care disciplines in different ICU environments. Our results have potential implications for patient care. First, when clinicians alter the content of their goals-of-care conversations with patients or families to accommodate intrateam discordance (as part of the "pas-de-deux"), subsequent decisions regarding medical care may be compromised. Second, when different team members respond differently to the same case-with nurses becoming more emotionally invested and physicians becoming more withdrawn-communication gaps are likely to occur at critical moral distress junctures. Finally, our findings suggest that physicians and any healthcare professionals in surgical units might be susceptible to unmitigated moral distress because they report less engagement in constructive behaviors to recalibrate their distress.

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.

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.

Although the mechanisms and pathways mediating ARDS have been studied extensively, less attention has been given to the mechanisms and pathways that counteract injury responses. This study found that the apelin-APJ pathway is an endogenous counterinjury mechanism that protects against ARDS. ⋯ The apelin-APJ signaling pathway is an endogenous anti-injury and organ-protective mechanism that is activated during ARDS to counteract the injury response and to prevent uncontrolled lung injury.
