OBJECTIVE
The aim of this study was to evaluate the occurrence and factors predisposing to delirium following brain tumor resection.
MATERIALS AND METHODS
Data from patients who underwent brain tumor resection surgery from 2016 to 2019 was extracted from the National Inpatient Sample (NIS) database and retrospectively analyzed. The difference between the two groups was compared by Wilcoxon rank test or Chi-square test were used to. Univariate and multivariate logistic regression analyses were used to identify the risk factors delirium after brain tumor resection.
RESULTS
From 2016 to 2019, 28340 patients who underwent brain tumor resection were identified in the NIS database, with the incidence of delirium being 4.79% (1357/28340). It was found that increased incidence of delirium was significantly associated with aged over 75 years and males (all P < 0.001). Besides, patients with delirium were more likely to have multiple comorbidities and to receive elective surgery (all P < 0.001). The results of logistic regression analysis showed that self-pay (OR = 0.51; CI = 0.31-0.83; P = 0.007), elective admission (OR = 0.53; CI = 0.47-0.60; P < 0.001), obesity (OR = 0.77; CI = 0.66-0.92; P = 0.003), female (OR = 0.79; CI = 0.71-0.88; P < 0.001), and private insurance (OR = 0.80; CI = 0.67-0.95; P = 0.012) were associated with lower occurrence of delirium. Besides, delirium was related to extra total hospital charges (P < 0.001), increased length of stay (P < 0.001), higher inpatient mortality (P = 0.001), and perioperative complications (including heart failure, acute renal failure, urinary tract infection, urinary retention, septicemia, pneumonia, blood transfusion, and cerebral edema) (P < 0.001).
CONCLUSION
Many factors were associated with the occurrence of delirium after brain tumor resection. Therefore, clinicians should identify high-risk patients prone to delirium in a timely manner and take effective management measures to reduce adverse outcomes.

Journal of Nursing Care Quality Jun 2024Frailty is independently associated with adverse patient outcomes after surgery. The current standards of postoperative care rarely consider frailty status.
BACKGROUND
Frailty is independently associated with adverse patient outcomes after surgery. The current standards of postoperative care rarely consider frailty status.
LOCAL PROBLEM
There was no standardized protocol to optimize specialized postoperative care for frail patients at an academic medical center.
METHODS
A quasi-experimental pre-/postimplementation study design, using the Reach, Effectiveness, Adoption, Implementation, Maintenance implementation framework, was utilized.
INTERVENTIONS
A frailty-specific postoperative order set (FPOS) was developed, including tailored nursing care, activity levels, and nutritional goals.
RESULTS
There were significant improvements in nurse's self-reported familiarity with frailty (P = .003) and FPOS awareness (P < .001). The number of orders for delirium prevention, elimination, nutrition, sleep promotion, and sensory support increased (P < .001).
CONCLUSIONS
Implementing an FPOS showed improvements in nurse frailty knowledge, awareness, and order set utilization.

Review
STUDY OBJECTIVE
Depression is a common cause of long-lasting disability and preoperative mental health state that has important implications for optimizing recovery in the perioperative period. In older elective surgical patients, the prevalence of preoperative depression and associated adverse pre- and postoperative outcomes are unknown. This systematic review and meta-analysis aimed to determine the prevalence of preoperative depression and the associated adverse outcomes in the older surgical population.
DESIGN
Systematic review and meta-analysis.
SETTING
MEDLINE, MEDLINE Epub Ahead of Print and In-Process, In-Data-Review & Other Non-Indexed Citations, Embase/Embase Classic, Cochrane CENTRAL, and Cochrane Database of Systematic Reviews, ClinicalTrials.Gov, the WHO ICTRP (International Clinical Trials Registry Platform) for relevant articles from 2000 to present.
PATIENTS
Patients aged ≥65 years old undergoing non-cardiac elective surgery with preoperative depression assessed by tools validated in older adults. These validated tools include the Geriatric Depression Scale (GDS), Hospital Depression and Anxiety Scale (HADS), Beck Depression Inventory-II (BDI), Patient Health Questionnaire-9 (PHQ-9), and the Centre for Epidemiological Studies Depression Scale (CESD).
INTERVENTIONS
Preoperative assessment.
MEASUREMENT
The primary outcome was the prevalence of preoperative depression. Additional outcomes included preoperative cognitive impairment, and postoperative outcomes such as delirium, functional decline, discharge disposition, readmission, length of stay, and postoperative complications.
MAIN RESULTS
Thirteen studies (n = 2824) were included. Preoperative depression was most assessed using the Geriatric Depression Scale-15 (GDS-15) (n = 12). The overall prevalence of preoperative depression was 23% (95% CI: 15%, 30%). Within non-cancer non-cardiac mixed surgery, the pooled prevalence was 19% (95% CI: 11%, 27%). The prevalence in orthopedic surgery was 17% (95% CI: 9%, 24%). In spine surgery, the prevalence was higher at 46% (95% CI: 28%, 64%). Meta-analysis showed that preoperative depression was associated with a two-fold increased risk of postoperative delirium than those without depression (32% vs 23%, OR: 2.25; 95% CI: 1.67, 3.03; I: 0%; P ≤0.00001).
CONCLUSIONS
The overall prevalence of older surgical patients who suffered from depression was 23%. Preoperative depression was associated with a two-fold higher risk of postoperative delirium. Further work is needed to determine the need for depression screening and treatment preoperatively.

OBJECTIVE
The main aim of our study is to know the sociodemographic, clinical, analytical, and functional variables that predict the probability of developing dementia in patients with delirium who attend the emergency room.
METHOD
All patients with delirium (n=45) from the emergency room who were admitted to the Geriatrics service of the General University Hospital of Ciudad Real (HGUCR) in 2016-2018 and met the inclusion and exclusion criteria were included. Subsequently, we ran a bivariate and multivariate analysis of the variables that predicted a diagnosis of dementia at six months and a discriminant analysis.
RESULTS
15.6% of patients presented dementia at six months of follow-up, 22.2% had developed cognitive impairment. We conducted a multivariate model (R2 Nagelkerke 0.459) for the probability of developing dementia, with elevated heart rate being the most crucial variable (OR=11.5). The model could excluded dementia with 100% accuracy. Finally, we achieved a discriminant function capable of correctly classifying 95.6% of the cases. It included the following variables of influence: pH, Lawton Brody index, calcium, urea, and heart rate.
CONCLUSIONS
A few clinical and analytical variables that are easily detectable in the emergency room, especially tachycardia, could help us better identify those patients with delirium at higher risk of developing dementia, as well as formulate hypotheses about the variables involved in the development of dementia in patients with delirium.

INTRODUCTION
We present our surgical complications resulting in neurological deficit or additional surgery during 25 years of DBS of the subthalamic nucleus (STN) for Parkinson's disease (PD).
METHODS
We conducted a retrospective chart review of all PD patients that received STN DBS in our DBS center between 1998 and 2023. Outcomes were complications resulting in neurological deficit or additional surgery. Potential risk factors (number of microelectrode recording tracks, age, anesthesia method, hypertension, and sex) for symptomatic intracerebral hemorrhage (ICH) were analyzed. Furthermore, lead fixation techniques were compared.
RESULTS
Eight hundred PD patients (507 men, 293 women) received unilateral (n = 11) or bilateral (n = 789) implantation of STN electrodes. Neurological deficit due to ICH, edema, delirium, or infarction was seen in 8.4% of the patients (7.4% transient, 1.0% permanent). Twenty-two patients (2.8%) had a symptomatic ICH following STN DBS, for which we did not find any risk factors, and five had permanent sequelae due to ICH (0.6%). Of all patients, 18.4% required additional surgery; the proportion was reduced from 27% in the first 300 cases to 13% in the last 500 cases (p < 0.001). The infection rate was 3.5%, which decreased from 5.3% in the first 300 cases to 2.2% in the last 500 cases. The use of a lead anchoring device led to significantly less lead migrations than miniplate fixation.
CONCLUSION
STN DBS leads to permanent neurological deficit in a small number of patients (1.0%), but a substantial proportion needs some additional surgical procedure after the first DBS system implantation. The risk of revision surgery was reduced over time but remained significant. These findings need to be discussed with the patient in the preoperative informed consent process in addition to the expected health benefit.

OBJECTIVE
Postoperative delirium (POD), a common complication affecting short- and long-term prognosis in elderly patients, leads to a heavy burden on social economy and health care. The main purpose of this study is to conduct a bibliometric analysis of the 100 most frequently cited articles on POD.
METHODS
"Postoperative delirium" and its synonyms were searched in the Web of Science (WoS) core database. The top-100 cited articles were automatically selected by sorting the records in descending order. Key information such as author, journal, article type, publication year, citations, since 2013 usage count, institution, country, and keywords were extracted and analyzed. VOSviewer software was applied to do the visualization analyses of institution co-operation, author interaction, author co-citation, and keywords co-occurrence. The CiteSpace software was used to analyze keywords burst.
RESULTS
Most articles were published by authors and institutions in the United States of America (USA). Inouye was the most influential author of this field. The journals that recorded these articles had a high impact factor (IF), with a highest IF of 168.9 and an average IF of 18.04. Cohort studies were the main document type in this field (42 publications), followed by randomized controlled trial (RCT) and systematic reviews or meta-analysis (18 and 14, respectively). The 10 keywords with the highest appearance were "delirium", "risk-factors", "surgery", "confusion assessment method", "elderly patients", "hip fracture", "intensive care unit", "cardiac surgery", "general anesthesia", and "risk". Moreover, "double blind" and "cardiac surgery" were the most recent booming keywords.
CONCLUSION
We indicated the current research status and tendency of POD by analyzing the 100 most influential articles on POD. The USA is the leader in this field. Prospective study is the preference for authors to cite. Cardiac surgery remains the primary research carrier and the hotspots in the near future may be double-blind studies.

This report aims to present an elderly woman with persistent delirium after hospitalization for lethargy secondary to hyponatremia. The diagnosis of pontine myelinolysis was made and there were no characteristic neurological manifestations such as pupillary changes or spastic tetraparesis. Hallucinations and personality changes were the clues to the diagnosis and should be considered an atypical manifestation of pontine myelinolysis.

Effect of Preoperative Clear Liquid Consumption on Postoperative Recovery in Pediatric Patients Undergoing Minimally Invasive Repair of Pectus Excavatum: A Prospective Randomized Controlled Study.
: Preoperative fasting guidelines traditionally aim to reduce pulmonary aspiration risk. However, concerns over the adverse effects of prolonged fasting have led to exploring alternatives. This study aimed to investigate the impact of preoperative clear liquid intake on postoperative outcomes in children undergoing minimally invasive repair of pectus excavatum (MIRPE). : A prospective randomized controlled study was conducted on children aged 3-6 years scheduled for elective MIRPE. Patients were randomized into either a routine overnight fasting group (NPO) or a clear liquid group. The incidence and severity of emergence delirium (ED) were assessed using Pediatric Anesthesia Emergence Delirium (PAED) and Watcha scales at recovery room. Postoperative pain scores and opioid requirements were evaluated at intervals of 1-6 h, 6-12 h, and 12-24 h after surgery. : Fasting time was 178.6 ± 149.5 min and 608.9 ± 148.4 min in the clear liquid group compared and NPO group, respectively. The incidence of ED, measured by PAED and Watcha scales, was lower in the clear liquid group (PAED score ≥ 12: 55.6% vs. 85.2%, = 0.037; Watcha score ≥ 3: 51.9% vs. 85.2%, = 0.019). The highest PAED score recorded in the recovery room was significantly lower in the clear liquid group (11.4 ± 2.8 vs. 14.6 ± 2.8, < 0.001). Clear liquid group showed significantly lower pain scores at 1-6, 6-12, and 12-24 h postoperatively. Additionally, clear liquid group had lower opioid requirement at 1-6 and 6-12 h postoperatively. : Preoperative clear liquid consumption was associated with a lower incidence of ED in pediatric patients undergoing MIRPE.

Association between Dexmedetomidine Use and Mortality in Patients with COVID-19 Receiving Invasive Mechanical Ventilation: A U.S. National COVID Cohort Collaborative (N3C) Study.
(1) : Dexmedetomidine is a sedative for patients receiving invasive mechanical ventilation (IMV) that previous single-site studies have found to be associated with improved survival in patients with COVID-19. The reported clinical benefits include dampened inflammatory response, reduced respiratory depression, reduced agitation and delirium, improved preservation of responsiveness and arousability, and improved hypoxic pulmonary vasoconstriction and ventilation-perfusion ratio. Whether improved mortality is evident in large, multi-site COVID-19 data is understudied. (2) : The association between dexmedetomidine use and mortality in patients with COVID-19 receiving IMV was assessed. This retrospective multi-center cohort study utilized patient data in the United States from health systems participating in the National COVID Cohort Collaborative (N3C) from 1 January 2020 to 3 November 2022. The primary outcome was 28-day mortality rate from the initiation of IMV. Propensity score matching adjusted for differences between the group with and without dexmedetomidine use. Adjusted hazard ratios (aHRs) for 28-day mortality were calculated using multivariable Cox proportional hazards models with dexmedetomidine use as a time-varying covariate. (3) : Among the 16,357,749 patients screened, 3806 patients across 17 health systems met the study criteria. Mortality was lower with dexmedetomidine use (aHR, 0.81; 95% CI, 0.73-0.90; < 0.001). On subgroup analysis, mortality was lower with earlier dexmedetomidine use-initiated within the median of 3.5 days from the start of IMV-(aHR, 0.67; 95% CI, 0.60-0.76; < 0.001) as well as use prior to standard, widespread use of dexamethasone for patients on respiratory support (prior to 30 July 2020) (aHR, 0.54; 95% CI, 0.42-0.69; < 0.001). In a secondary model that was restricted to 576 patients across six health system sites with available PaO/FiO data, mortality was not lower with dexmedetomidine use (aHR 0.95, 95% CI, 0.72-1.25; = 0.73); however, on subgroup analysis, mortality was lower with dexmedetomidine use initiated earlier than the median dexmedetomidine start time after IMV (aHR, 0.72; 95% CI, 0.53-0.98; = 0.04) and use prior to 30 July 2020 (aHR, 0.22; 95% CI, 0.06-0.78; = 0.02). (4) : Dexmedetomidine use was associated with reduced mortality in patients with COVID-19 receiving IMV, particularly when initiated earlier, rather than later, during the course of IMV as well as use prior to the standard, widespread usage of dexamethasone during respiratory support. These particular findings might suggest that the associated mortality benefit with dexmedetomidine use is tied to immunomodulation. However, further research including a large randomized controlled trial is warranted to evaluate the potential mortality benefit of DEX use in COVID-19 and evaluate the physiologic changes influenced by DEX that may enhance survival.

The aim of the current investigation was to compare the ability of several frailty scores to predict adverse outcomes in hip fracture patients. All adult patients (18 years or older) who suffered a hip fracture due to a fall and underwent surgical fixation were extracted from the 2019 National Inpatient Sample (NIS) Database. A combination of logistic regression and bootstrapping was used to compare the predictive ability of the Orthopedic Frailty Score (OFS), the Nottingham Hip Fracture Score (NHFS), the 11-factor modified Frailty Index (11-mFI) and 5-factor (5-mFI) modified Frailty Index, as well as the Johns Hopkins Frailty Indicator. A total of 227,850 patients were extracted from the NIS. In the prediction of in-hospital mortality and failure-to-rescue (FTR), the OFS surpassed all other frailty measures, approaching an acceptable predictive ability for mortality [AUC (95% CI): 0.69 (0.67-0.72)] and achieving an acceptable predictive ability for FTR [AUC (95% CI): 0.70 (0.67-0.72)]. The NHFS demonstrated the highest predictive ability for predicting any complication [AUC (95% CI): 0.62 (0.62-0.63)]. The 11-mFI exhibited the highest predictive ability for cardiovascular complications [AUC (95% CI): 0.66 (0.64-0.67)] and the NHFS achieved the highest predictive ability for delirium [AUC (95% CI): 0.69 (0.68-0.70)]. No score succeeded in effectively predicting venous thromboembolism or infections. In summary, the investigated frailty scores were most effective in predicting in-hospital mortality and failure-to-rescue; however, they struggled to predict complications.
