Abstract
Delirium is an acute brain dysfunction. As one of the common psychiatric disorders in ICU, it can seriously affect the prognosis of patients. Hormones are important messenger substances found in the human body that help to regulate and maintain the function and metabolism of various tissues and organs. They are also one of the most commonly used drugs in clinical practice. Recent evidences suggest that aberrant swings in cortisol and non-cortisol hormones might induce severe cognitive impairment, eventually leading to delirium. However, the role of hormones in the pathogenesis of delirium still remains controversial. This article reviews the recent research on risk factors of delirium and the association between several types of hormones and cognitive dysfunction. These mechanisms are expected to offer novel ideas and clinical relevance for the treatment and prevention of delirium.

[PMID: 35624556 DOI: 10.1111/nicc.12780] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2021] [Revised: 04/22/2022] [Accepted: 05/06/2022] [Indexed: 11/28/2022]
Abstract
BACKGROUND Delirium is a common complication among patients in the intensive care unit (ICU). It is important to prevent the occurrence of delirium in critically ill patients. AIM This review aimed to evaluate the efficacy of non-pharmacological interventions and determine what combination of these is effective in preventing delirium among Intensive Care Unit patients. STUDY DESIGN A systematic review and meta-analysis. This review follows the guidelines of the Preferred Reporting Items for Systematic reviews and Meta Analysis statements for Network Meta-Analysis (PRISMA-NMA). Data sources included the Cumulative Index to Nursing & Allied Health Literature., MEDLINE, and Cochrane library databases. The integrated data were investigated with odds ratio (OR) and 95% confidence interval (95% CI), using the random-effects Mantel-Haenszel model. Data were considered significant when p < 0.05. Furthermore, to reveal what combination of care is effective, we performed a network meta-analysis estimated OR, 95% CI. RESULTS We identified three randomized controlled trials and eight controlled before-after trials (11 in total, with 2549 participants). The pooled data from 11 trials of multicomponent intervention had a significant effect on delirium prevention (OR 0.58, 95% CI 0.44-0.76, p < 0.001). As a result of network meta-analysis, two bundles were effective compared to the control group in reducing the incidence of delirium: a) the combination of sleep promotion (SP), cognitive stimulation (CS), early mobilization (EM), pain control (PC), and assessment (AS) (OR 0.47, 95% CI 0.35-0.64, p < 0.002), and b) the combination of SP and CS (OR 0.46, 95% CI 0.28-0.75, p < 0.001). CONCLUSION This study revealed that non-pharmacological interventions, particularly multicomponent interventions, helped to prevent delirium in critically ill patients. In the network meta-analysis, the most effective care combination for reducing incidence of delirium was found to be multicomponent intervention, which comprises SP-CS-EM-PC-AS, and SP-CS. RELEVANCE TO CLINICAL PRACTICE These findings reveal an efficient combination of multicomponent interventions for preventing delirium, which may be a very important prerequisite in planning care programs in the future.

Abstract
To investigate the effect of preoperative tropisetron treatment on postoperative cognitive function on the basis of patients' Mini-Cog scale scores. In this retrospective cohort study, data were retrieved from the medical record database. This research did not involve concerns with patient safety and violation of their interests, and therefore, no ethical review was required. Depending on tropisetron exposure status, patients were assigned to the exposure group (86 patients) and the non-exposure group (74 patients). Patients in the exposure and non-exposure groups were administered tropisetron (10 mg; intravenously 15 minutes before operation) and other antiemetics, respectively. Data on the patients' demographic characteristics, American society of Anesthesiologists (ASA) classification, comorbid underlying diseases, sleep quality, education level, anesthesia method, duration of fasting, intraoperative blood loss and fluid replacement, intraoperative minimum and maximum systolic blood pressures (SBPs), intraoperative minimum and maximum diastolic blood pressures (DBPs), postoperative Mini-Cog scale (a simple intelligence status assessment scale) score, and postoperative visual analogue scale (VAS) pain score were collected in both the groups. The postoperative Mini-Cog score (as an indicator of cognitive function) and the rate of postoperative cognitive impairment were compared between the exposure and non-exposure groups. A multifactorial logistic regression equation was constructed to analyze the factors associated with impaired cognitive function in the postoperative period. The postoperative cognitive impairment rate in the exposure group was significantly lower than that in the non-exposure group (3.5% vs 16.2%; P < .05). Multifactorial logistic regression analysis suggested that tropisetron was a protective factor for postoperative cognitive function, with a statistically significant effect (odds ratio [OR] = 5.04, 95% confidence interval [CI] = 1.31-19.4). Preoperative tropisetron exposure significantly reduces the incidence of postoperative cognitive impairment in patients, and it is a protective factor for postoperative cognitive function.

Abstract
Background Dopamine is widely used in patients during surgery. We evaluated the association between intraoperative low-dose dopamine administration and recurrence-free survival (RFS) and overall survival (OS) in patients with hepatocellular carcinoma (HCC). Methods Consecutive patients with nonmetastatic HCC who underwent radical hepatectomy were enrolled between 2008 and 2010. Univariate and multivariate logistic regression analyses were used to evaluate the prognostic factors for RFS and OS. Survival outcomes were evaluated using Kaplan–Meier analyses with the log-rank test. A one-to-one propensity score matching (PSM) analysis was performed to reduce confounding bias. Results A total of 805 HCC patients, including 699 patients who did not receive dopamine consumption and 106 patients who received low-dose dopamine during the operation, were retrospectively analyzed. The patients who were assigned low-dose dopamine had worse RFS (p = 0.009) and OS (p = 0.041) than those who did not receive dopamine. Multivariate regression analysis showed that the intraoperative administration of low-dose dopamine was an independent unfavorable predictor for RFS (p = 0.004) but not for OS (p = 0.059). After PSM, the low-dose dopamine-treated group still had significantly poorer RFS (p = 0.003) and OS (p = 0.002). When stratified by time of recurrence, patients with low-dose dopamine use had a significantly greater chance of recurrence within 2 years (p = 0.007) but not after 2 years (p = 0.186). Conclusions Intraoperative low-dose dopamine use has a negative impact on RFS and OS in HCC patients who have undergone radical hepatectomy. Further prospective studies are required to assess the effects of low-dose dopamine on surgical outcomes in HCC patients.

Abstract
BACKGROUND Mental health and wellbeing continue to gain more attention as they are inextricably associated with clinical outcomes, particularly quality of life. Many medical ailments and major surgeries affect patients' mental health, including depression and delirium. AIMS The objective of this manuscript was to comprehensively review and critically examine the literature pertaining to cardiac surgery, depression, and delirium. METHODS This is a narrative review article. We performed our search analysis by using the following key words: "Cardiac Surgery", "Depression", "Delirium", "Clinical outcomes", and "Mental Health". Search analysis was done on MedLine PubMed, accessing indexed peer-reviewed publications. RESULTS Cardiac Surgery is a life-altering intervention indicated to improve morbidity and mortality in patients with cardiovascular diseases. Psychiatric conditions before and after cardiac surgery worsen patient prognosis and increase mortality rate. Specifically, preoperative depression increases postoperative depression and is associated with impaired functional status, slow physical recovery, and an increased readmission rate. DISCUSSION Although the exact pathophysiology between depression and cardiovascular disease (CVD) is unknown, several pathways have been implicated. Unmanaged depression can also lead to other psychological conditions such as delirium. Like depression, the exact association between delirium and CVD is not well understood, but believed to be multifactorial. CONCLUSION Herein, we provide a comprehensive review of the links between depression, delirium, and cardiovascular surgery. We critically examine the current data that pertains to the pathophysiology of these debilitating mental health issues in the context of cardiac surgery. Finally, we summarize the various treatment options available for managing depression and delirium in the cardiac surgery patient population.

Abstract
Background Coronary artery bypass grafting (CABG) is known to improve heart function and quality of life, while rates of surgery‐related mortality are low. However, delirium and cognitive decline are common complications. We sought to identify preoperative, intraoperative, and postoperative risk or protective factors associated with delirium and cognitive decline (across time) in patients undergoing CABG. Methods and Results We conducted a systematic search of Medline, PsycINFO, EMBASE, and Cochrane (March 26, 2019) for peer‐reviewed, English publications reporting post‐CABG delirium or cognitive decline data, for at least one risk factor. Random‐effects meta‐analyses estimated pooled odds ratio for categorical data and mean difference or standardized mean difference for continuous data. Ninety‐seven studies, comprising data from 60 479 patients who underwent CABG, were included. Moderate to large and statistically significant risk factors for delirium were as follows: (1) preoperative cognitive impairment, depression, stroke history, and higher European System for Cardiac Operative Risk Evaluation (EuroSCORE) score, (2) intraoperative increase in intubation time, and (3) postoperative presence of arrythmia and increased days in the intensive care unit; higher preoperative cognitive performance was protective for delirium. Moderate to large and statistically significant risk factors for acute cognitive decline were as follows: (1) preoperative depression and older age, (2) intraoperative increase in intubation time, and (3) postoperative presence of delirium and increased days in the intensive care unit. Presence of depression preoperatively was a moderate risk factor for midterm (1–6 months) post‐CABG cognitive decline. Conclusions This meta‐analysis identified several key risk factors for delirium and cognitive decline following CABG, most of which are nonmodifiable. Future research should target preoperative risk factors, such as depression or cognitive impairment, which are potentially modifiable.

Abstract
Objective To investigate dysregulated molecules in preoperative cerebrospinal fluid (CSF) of elderly hip fracture patients with postoperative delirium (POD), in order to identify potential pathological mechanisms and biomarkers for pre-stage POD. Materials and Methods This nested case control study used untargeted metabolomic and lipidomic analysis to profile the preoperative CSF of patients (n = 40) who developed POD undergone hip fracture surgery (n = 10) and those who did not (n = 30). Thirty Non-POD patients were matched to 10 POD patients by age (± 2 years) and Mini Mental State Examination score (± 2 points). CSF was collected after successful spinal anesthesia and banked for subsequent analysis. On the first two postoperative days, patients were assessed twice daily using the Confusion Assessment Method-Chinese Revision. CSF samples from the two groups were analyzed to investigate possible relevant pathological mechanisms and identify candidate biomarkers. Results Demographic characteristics of the groups were matched. Eighteen metabolites and thirty-three lipids were dysregulated in the preoperative CSF of POD patients. Pathway enrichment analysis revealed perturbations in D-glutamine and D-glutamate metabolism; glycerophospholipid metabolism; alanine, aspartate and glutamate metabolism; sphingolipid metabolism; histidine metabolism; and arginine biosynthesis at the pre-delirium stage. Receiver operating characteristic curve analysis indicated that phosphatidylethanolamine (PE, 40:7e), with an area under the curve value of 0.92, is a potential biomarker for POD. Conclusion Multiple pathological mechanisms in the POD group were involved before surgery, including neuroinflammation, oxidative stress, and energy metabolism disorders induced by hypoxia, as well as neurotransmitter imbalances such as increased dopamine and glutamate, and decreased glutamine. These metabolic abnormalities potentially increase the fragility of the brain, thus contributing to POD. PE (40:7e) might be a potential biomarker for POD. Not only do our results provide potential biomarkers for POD, but also provide information for deep pathological research.

Abstract
Delirium, an acute alteration in mental status characterized by confusion, inattention and a fluctuating level of arousal, is a common problem in critically ill patients. Delirium prolongs hospital stay and is associated with higher mortality. The pathophysiology of delirium has not been fully elucidated. Neuroinflammation and neurotransmitter imbalance seem to be the most important factors for delirium development. In this review, we present the most important pathomechanisms of delirium in critically ill patients, such as neuroinflammation, neurotransmitter imbalance, hypoxia and hyperoxia, tryptophan pathway disorders, and gut microbiota imbalance. A thorough understanding of delirium pathomechanisms is essential for effective prevention and treatment of this underestimated pathology in critically ill patients.

Abstract
BACKGROUND Postoperative delirium (POD) describes a multifactorial disease process occurring after surgery. However, few studies have focused on patients undergoing brain tumor resection, and its influencing factors are unclear. METHODS We performed a 1-year, single-center, cross-sectional, retrospective survey at Huashan Hospital. Patients were screened using the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU), Confusion Assessment Method, and Richmond Agitation Sedation Scale by trained bedside nurses. Perioperative data were collected using demographic and disease-related questionnaires. The primary outcome measures were the incidence of POD and subtype of POD. Independent predictors of POD were estimated from multivariate logistic regression models, and receiver operating characteristic analysis was used to compare the predictive performance of the models. RESULTS Of the 916 patients included in the study, 893 were analyzed. The overall incidence was 14.78%, 67 had hyperactive delirium (50.76%), 55 had hypoactive delirium (41.67%), and 10 had mixed delirium (7.57%). Age, sex, working status, tobacco use history, comorbidities, physical restraint, axillary temperature (>38.5°C), electrolyte disturbances, duration of anesthesia, pathologic diagnosis, tumor site, length of disease, and duration of operation were risk factors for POD. Conversely, saddle area mass was a protective factor. Age, tobacco use history, electrolyte disturbances, physical restraint, and duration of operation were included in the model. CONCLUSIONS POD is harmful to patients undergoing brain tumor resection, increasing length of stay in the intensive care unit and hospitalization costs. Intraoperative factors and postoperative factors, in addition to older age and tobacco use history, are associated with POD.

Abstract
Postoperative delirium (POD) is a neurobehavioral syndrome caused by dysfunction of neural activity mainly in elderly people. POD is not uncommon, but under-recognized, and often serious. Multifactorial causes including aging, acetylcholine deficiency, sleep deprivation and intraoperative hypoxia have been proposed attempting to explain the processes leading to the development of POD. To date, however, no specific pathophysiologic mechanism has been identified. Here, we summarize the five most prominent theories (neuronal aging, neuroinflammation, neurotransmitter imbalance, neuroendocrine activation, and network connectivity change) to explain the development of delirium. Understanding of the neuropathogenesis of delirium will help focus future research, and assist in developing prophylactic and treatment strategies.

Chen Y, Ding S, Tao X, Feng X, Lu S, Shen Y, Wu Y, An X. The quality of life of patients developed delirium after coronary artery bypass grafting is determined by cognitive function after discharge: A cross-sectional study. Int J Nurs Pract 2017; 23. [PMID: 28752905 DOI: 10.1111/ijn.12563] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2016] [Revised: 03/21/2017] [Accepted: 04/30/2017] [Indexed: 12/14/2022]
Abstract
AIMS Postoperative delirium (POD) and declined cognitive function were common in patients (especially elderly patients) who underwent coronary artery bypass grafting (CABG), which may affect quality of life (QoL). The aim of this study was to determine the relationships among age, POD, declined cognitive function, and QoL in patients who underwent CABG. METHODS Consecutive patients who underwent first time elective CABG and assessed for POD using Confusion Assessment Method for intensive care unit for 5 postoperative days from November 2013 to March 2015 were recruited. A cross-sectional study was conducted during April 2015 to assess their cognitive function and QoL, using the Telephone Interview for Cognitive Status Scale and Medical Outcomes Study 36-Item Short Form Health Survey. The relationships among age, POD, declined cognitive function, and QoL were tested using path analysis. RESULTS Declined cognitive function was associated with poorer QoL. POD was associated with declined cognitive function but was not associated with poorer QoL. Ageing was not associated with QoL but was associated with POD and declined cognitive function. CONCLUSION The QoL of patients developed delirium after CABG is determined by cognitive function after discharge. Necessary strategies should be implemented to prevent POD and declined cognitive function, especially in elderly patients.
