Review
BACKGROUND
Postoperative acute kidney injury (AKI) is a serious and distressing complication connected to various adverse outcomes following the surgical operation. Controversy remains regarding the dexmedetomidine's preventive impact on postoperative AKI. Therefore, this investigation aims to explore the efficiency and safety of dexmedetomidine in preventing AKI after surgical operation.
METHODS
We systematically searched electronic databases such as PubMed, Embase, Web of Science, and the Cochrane Library to detect eligible randomized controlled studies that used dexmedetomidine for the prevention of AKI following operation up to April 30, 2023. The main outcome evaluated was AKI incidence. The evidence quality was assessed employing the Grading of Recommendations Assessment, Development, and Evaluation.
RESULTS
The meta-analysis included 25 trials, including 3,997 individuals. Of these, 2,028 were in the dexmedetomidine group, and 1,969 were in the control group. The result showed that patients administered dexmedetomidine significantly decreased the AKI incidence following surgical operation in contrast to the control group (risk ratio, 0.60; 95% confidence intervals, 0.45-0.78; < 0.05; = 46%). In addition, dexmedetomidine decreased the period of hospitalization in both the intensive care unit (ICU) and the hospital while also reducing postoperative delirium (POD) occurrence. However, dexmedetomidine elevated the incidence of bradycardia but did not have a significant impact on other indicators.
CONCLUSION
Our meta-analysis indicates that the dexmedetomidine treatment reduces the postoperative AKI and POD risk while also shortening the time of hospitalization in the ICU and hospital. However, it is connected to an increased bradycardia risk.

Industrial Psychiatry Journal 2024There is a dearth of research on risk factors of delirium among elderly inpatients in nonintensive low resource settings.
BACKGROUND
There is a dearth of research on risk factors of delirium among elderly inpatients in nonintensive low resource settings.
AIM
To determine the risk factors of delirium in elderly inpatients in a nonintensive care unit setting.
MATERIALS AND METHODS
Sixty two elderly patients with delirium (cases) and 62 patients without delirium (controls) were administered a semi-structured proforma with socio-demographic variables and putative predisposing and precipitating risk factors and the Vellore screening instrument for dementia.
RESULTS
On univariate analysis, factors such as past cognitive impairment, history of nocturnal confusion and delirium, diminished daily living activities, severe medical illness, history of psychiatric illness, presence of dementia, infection, fever above 100F, abnormal electrolytes abnormal RFT, leukocytes in urine, hypoxia, anticholinergics and benzodiazepines, emergency admission, use of physical restraints, bladder catheterization, more than routine investigations, intensive care unit admission, surgery, and duration of hospital stay more than 10 days were found to be significantly associated with delirium. On multivariate analysis with binary logistic regression, bladder catheterization (odds ratio [OR] = 13.85; confidence interval [CI] = 1.44-133.14), abnormal electrolytes (OR = 5.12; CI = 1.11-23.69), and hypoxia (OR = 75.52; CI = 4.64-1.134E3) were detected to be independently associated with delirium.
CONCLUSION
Acute modifiable rather than long-term factors were risk factors for delirium among the elderly. An awareness of modifiable risk factors has the potential of developing targeted interventions for the early mitigation of delirium.

A 57-year-old man was admitted to our hospital via the ED presenting in reduced general condition because of an infection of unknown origin, generalized edema, and dyspnea at rest (peripheral capillary oxygen saturation, 89%) that required 2 L/min intranasal oxygen. Anamnesis was complicated by an infection-triggered delirium, but his wife reported an increasing physical decay that had led to bed confinement. The BP was reduced at 88/55 mm Hg with a normal heart rate of 86 beats/min. Lung auscultation showed mild bipulmonal rales. Previous comorbidities were a BMI of 42 kg/m, an insulin-dependent type 2 diabetes mellitus with a severe diabetes-related chronic kidney disease stage G4A3, and systemic arterial hypertension.

BACKGROUND Emergence agitation, or delirium, occurs during early recovery from general anesthesia and involves disorientation, excitation, and uncontrolled physical movements. Dexmedetomidine is an alpha agonist that has sedative, anxiolytic, analgesic, and sympatholytic activities and is used as a continuous infusion to prevent emergence agitation. This study aimed to evaluate patients aged 65 years and older undergoing general anesthesia to determine the 90% effective dose (ED90) of dexmedetomidine continuous intraoperative infusion to prevent emergence agitation. MATERIAL AND METHODS We enrolled 44 patients aged 65 years and older undergoing spinal surgery under general anesthesia. Dexmedetomidine administration commenced 30 minutes before surgery completion, with a predetermined infusion dose (μg/kg/h), without a loading dose. The initial dose was 0.2 μg/kg/h, and subsequent step size was ±0.05 μg/kg/h. We tried to find ED90 of dexmedetomidine using the biased-coin design. Vital signs, extubation quality scores, extubation-related complications, and postoperative outcomes were monitored. RESULTS Dexmedetomidine ED₉₀ for smooth emergence in older patients was 0.34 μg/kg/h. Peri-extubation vital signs remained within 20% of baseline values, without requiring pharmacological intervention. No hypoxia, hypoventilation, or post-extubation agitation occurred. In the recovery room, 1 patient briefly exhibited excitement but quickly calmed. Nine patients initially unresponsive in the recovery room fully awoke and were promptly discharged. CONCLUSIONS For older patients who are vulnerable to adverse effects of anesthetics and opioids, dexmedetomidine enables gentle awakening without adverse vital sign changes, respiratory depression, excessive sedation, or emergence agitation (ED₉₀=0.34 μg/kg/h). Further studies should involve a larger patient cohort, considering diverse medical conditions in older individuals.

Clinical Trial
BACKGROUND
Data on overuse of diagnostic and therapeutic resources underline their contribution to the decline in healthcare quality. The application of "Do Not Do" recommendations, in interaction with gender biases in primary care, remains to be fully understood. Therefore, this study aims to identify which low-value practices (LVPs) causing adverse events are susceptible to be applied in primary care setting with different frequency between men and women.
METHODS
A consensus study was conducted between November 1, 2021, and July 4, 2022, in the primary care setting of the Valencian Community, Spain. Thirty-three of the 61 (54.1%) health professionals from clinical and research settings invited, completed the questionnaire. Participants were recruited by snowball sampling through two scientific societies, meeting specific inclusion criteria: over 10 years of professional experience and a minimum of 7 years focused on health studies from a gender perspective. An initial round using a questionnaire comprising 40 LVPs to assess consensus on their frequency in primary care, potential to cause serious adverse events, and different frequency between men and women possibly due to gender bias. A second round-questionnaire was administered to confirm the final selection of LVPs.
RESULTS
This study identified nineteen LVPs potentially linked to serious adverse events with varying frequencies between men and women in primary care. Among the most gender-biased and harmful LVPs were the use of benzodiazepines for insomnia, delirium, and agitation in the elderly, and the use of hypnotics without a previous etiological diagnosis.
CONCLUSIONS
Identifying specific practices with potential gender biases, mainly in mental health for the elderly, contributes to healthcare promotion and bridges the gap in gender inequalities.

BACKGROUND
Postoperative delirium (POD) and cognitive dysfunction (POCD) are common complications following thoracic surgery, particularly in patients aged 65 years and above. These complications can significantly affect recovery and increase healthcare costs. This study investigates the effects of low-dose S-ketamine on reducing POD and POCD in this patient demographic.
METHODS
In this retrospective cohort study, medical records of patients aged ≥ 65 years who underwent elective thoracic surgery from January 2019 to August 2023 were reviewed. Patients were categorized into S-ketamine and Control groups based on intraoperative S-ketamine exposure. POD was assessed using the Confusion Assessment Method (CAM), while cognitive function was evaluated using the Montreal Cognitive Assessment (MoCA) at baseline, 1 week, 1 month, and 6 months post-surgery. Intraoperative and postoperative parameters, including hemodynamic stability, blood loss, pain scores, and ICU stay length, were also recorded.
RESULTS
The study comprised 140 participants, with 70 in each group. The S-ketamine group demonstrated a significantly lower incidence of POD at 7 days post-surgery (12.0% vs. 26.7%, P < 0.001), and reduced POCD at 1 month (18.7% vs. 36.0%, P < 0.05) and 6 months (10.7% vs. 21.3%, P < 0.05). The Ketamine group had a significantly higher median MoCA score compared to the Control group both at 1 month (P = 0.021) and 6 months (P = 0.007). Adverse events, such as infection, bleeding, and respiratory failure, showed no significant differences between the groups, suggesting a safe profile for S-ketamine.
CONCLUSION
Administering low-dose S-ketamine during thoracic surgery in patients aged 65 years and above significantly reduces the incidence of POD and POCD, highlighting its neuroprotective potential. These findings advocate for the inclusion of S-ketamine in anesthetic protocols to improve postoperative outcomes and reduce healthcare costs in this patient population.

Combined nutritional status and activities of daily living disability is associated with one-year mortality after hip fracture surgery for geriatric patients: a retrospective cohort study.
OBJECTIVE
We aimed to explore the association combined nutritional status and activities of daily living disability with all-cause mortality of older adults with hip fracture in the first year after hospitalization.
METHODS
This is a single-center retrospective cohort study in older adults with hip fracture patients. Clinical data and laboratory results were collected from electronic medical record system of our hospital (2014-2021). The endpoint of this study was all-cause mortality in the first year after hospitalization.
RESULTS
A total of 303 older adults were enrolled and all-cause mortality was 21.8%. The study population was categorized by CONUT score. Patients in CONUT score 5-12 had a higher age, ASA status, CRP and creatinine level, more patients with history of fracture, pneumonia and delirium, meanwhile, lower BMI and ADL score, lower hemoglobin, lymphocyte, total protein, albumin, triglyceride, total cholesterol and one year survival than those in CONUT score 0-4 (all P < 0.05). Multivariable Cox analysis showed that BMI, ADL score and CONUT score were independent risk factors for all-cause mortality of hip fracture in older adults (HR (95% CI):2.808(1.638, 4.814), P < 0.001; 2.862(1.637, 5.003), P < 0.001; 2.322(1.236, 4.359), P = 0.009, respectively). More importantly, the combined index of CONUT and ADL score had the best predictive performance based on ROC curve (AUC 0.785, 95% CI: 0.734-0.830, P < 0.0001). Kaplan-Meier survival curves for all-cause mortality showed that patients with CONUT score increase and ADL score impairment had a higher mortality rate at 1 year compared to CONUT score decrease and ADL score well (Log Rank χ2 = 45.717, P < 0.0001).
CONCLUSIONS
Combined CONUT and ADL score is associated with one-year mortality after hip fracture surgery for geriatric patients.

Observational Study
INTRODUCTION
Psychiatric comorbidities have a significant impact on patients' quality of life and often go undetected in neurologic practice. The aim of this study was to describe and characterize psychiatric comorbidities among patients hospitalized due to a neurologic disorder in mainland Portugal.
METHODS
A retrospective observational study was performed by analyzing hospitalization with a primary diagnosis of neurologic disorder defined as categories 76, 77, 79 - 85, 95, 109 of the Clinical Classification Software for International Classification of Diseases, Ninth Revision, Clinical Modification, occurring between 2008 and 2015 in adult patients (≥ 18 years of age). Psychiatric comorbidities were determined as the presence of a secondary diagnosis belonging to the Clinical Classification Software categories 650 to 670.
RESULTS
A total of 294 806 hospitalization episodes with a primary diagnosis of a neurologic disorder were recorded in adult patients between 2008 - 2015 in Portuguese public hospitals. Approximately 26.9% (n = 79 442) of the episodes had a recorded psychiatric comorbidity (22.1%; 32.2%, female versus male hospitalizations). Patients with registered psychiatric comorbidities were younger (66.2 ± 16.2 vs 68.6 ± 17.2 with no psychiatric comorbidities, p < 0.001), presented lower all-cause in-hospital mortality rates, and significantly longer mean hospital stays. 'Delirium, dementia, amnestic and other cognitive disorders' were recorded in 7.4% (n = 21 965) of the hospitalizations, followed by alcohol-related disorders in 6.5% (n = 19 302) and mood disorders in 6.1% (n = 18 079). Epilepsy/seizures were the neurologic disorders with the highest proportion of recorded psychiatric comorbidities (39.9%).
CONCLUSION
Psychiatric comorbidities were recorded in more than a quarter of the hospitalizations with a primary diagnosis of a Neurologic disorder. Psychiatric comorbidities varied among neurological disorders and were associated with different demographic and clinical features.

Meta-Analysis
BACKGROUND
Previous findings on the effect of general versus spinal anesthesia on postoperative delirium in elderly people with hip fractures are somewhat controversial. This article included the latest randomized controlled study for meta-analysis to evaluate the effect of general anesthesia (GA) and spinal anesthesia (SA) on delirium after hip fracture surgery in the elderly, so as to guide the clinical.
METHODS
Cochrane Library, PubMed, Web Of Science, and Embase were searched from inception up to January 16, 2024. Randomized controlled trial (RCT) was included to evaluate the postoperative results of GA and SA in elderly patients (≥50 years old) undergoing hip fracture surgery. Two researchers independently screened for inclusion in the study and extracted data. Heterogeneity was assessed by the I²and Chi-square tests, and P < .1 or I² ≥ 50% indicated marked heterogeneity among studies. The Mantel-Haenszel method was used to estimate the combined relative risk ratio (RR) and the corresponding 95% confidence interval (CI) for the binary variables.
RESULTS
Nine randomized controlled trials were included. There was no significant difference (RR = 0.93, 95% CI = 0.774-1.111, P > .05) in the incidence of postoperative delirium between the GA group and the SA group. In intraoperative blood transfusion (RR = 1.0, 95% CI = 0.77-1.28, Z = 0.04, P = .971), pulmonary embolism (RR = 0.795, 95% CI = 0.332-1.904, Z = 0.59, P = .606), pneumonia (RR = 1.47, 95% CI = 0.75-2.87, P = .675), myocardial infarction (RR = 0.97, 95% CI = 0.24-3.86, Z = 0.05, P = .961), heart failure (RR = 0.80, 95% CI = 0.26-2.42, Z = 0.40, P = .961), urinary retention (RR = 1.42, 95% CI = 0.77-2.61, Z = 1.11, P = .267) were similar between the 2 anesthetic techniques.
CONCLUSION
There is no significant difference in the effect of GA and SA on postoperative delirium in elderly patients with hip fracture, and their effects on postoperative complications are similar.

INTRODUCTION
There has been increased interest in the use of Statins in total hip and knee arthroplasty (THA and TKA) patients to improve outcomes and reduce postoperative complications. This study was performed to systematically review the evidence on Statin use in total joint arthroplasty, specifically its benefits and complications.
METHODS
Adhering to the PRISMA guidelines, a systematic review of PubMed, Embase, Scopus, Web of Science, and the Cochrane database was performed to find studies reporting on the effects of Statin use on outcomes of THA and TKA. Two authors independently selected relevant papers to include.
RESULTS
A total of 18 papers were included in the final analysis. Most were retrospective studies, with heterogeneous patient selection and outcome measures. The evidence on the risks and benefits of Statin use on outcomes of total joint arthroplasty was very limited and heterogeneous. Studies were focusing on perioperative cardiac outcomes, clinical outcomes and complications, renal, pulmonary, and gastrointestinal outcomes. Due to the heterogeneity of reported data, a formal meta-analysis was not possible.
CONCLUSIONS
There is some evidence in the literature suggesting that perioperative use of Statins, especially in Statin-naïve patients, may reduce cardiac (e.g. atrial fibrillation) and noncardiac (e.g. delirium) complications, while not increasing the risk of muscle or liver toxicity. The authors also found low levels of evidence that Statin use may reduce the long-term risk for revision surgery and osteolysis.
