RESUMO
BACKGROUND: This meta-analysis aimed to evaluate the impact of ketamine/esketamine on postoperative subjective quality of recovery (QoR). METHODS: MEDLINE, Embase, Cochrane library, and Google Scholar were searched for randomised controlled trials (RCTs) that examined the impacts of perioperative ketamine/esketamine use and postoperative QoR. The primary outcome was subjective QoR (QoR-9, QoR-15, QoR-40) on postoperative day (POD) 1-3, whereas the secondary outcomes included pain severity, anxiety scores, depression scores, risk of adverse events (i.e. nausea, vomiting, dizziness, drowsiness), and length of stay. RESULTS: The analysis included 18 RCTs (1554 participants; ketamine: seven trials, esketamine: 11 trials), of which 15 were conducted in China. Ketamine/esketamine improved the QoR scores on PODs 1 and 2 compared with the control (standardised mean difference [SMD]: 0.63, P<0.0001 for POD 1; SMD: 0.56, P=0.04 for POD 2), without beneficial effect on POD 3. Subgroup analyses revealed significant differences in QoR scores on POD 1 by regimen (SMD: esketamine 1.14, ketamine 0.01) and country (SMD: China 0.82, other countries -0.21). The emotional domain of QoR was improved from PODs 1 to 3, whereas the other domains were only improved on POD 1. Lower postoperative anxiety (SMD: -0.48, P=0.003) and depression (SMD: -0.72, P=0.001) scores were also observed with ketamine/esketamine use. Furthermore, pain severity was reduced on PODs 1 and 2, with no difference in the risk of adverse events or length of stay. CONCLUSIONS: This meta-analysis demonstrated that ketamine/esketamine use in the perioperative period is associated with improved early subjective QoR, pain severity, and psychological symptoms without an increase in the likelihood of adverse events. SYSTEMATIC REVIEW PROTOCOL: PROSPERO (CRD42023477580).

BACKGROUND: Postoperative delirium (POD) is a common complication in the elderly, which is associated with poor outcomes after surgery. Recognized as predisposing factors for POD, anesthetic exposure and burst suppression during general anesthesia can be minimized with intraoperative processed electroencephalography (pEEG) monitoring. In this study, we aimed to evaluate whether implementation of intraoperative pEEG-guided anesthesia is associated with incidence change of POD. METHODS: In this retrospective evaluation study, we analyzed intravenous patient-controlled analgesia (IVPCA) dataset from 2013 to 2017. There were 7425 patients using IVPCA after a noncardiac procedure under general anesthesia. Patients incapable of operating the device independently, such as cognitive dysfunction or prolonged sedation, were declined and not involved in the dataset. After excluding patients who opted out within three days (N = 110) and those with missing data (N = 24), 7318 eligible participants were enrolled. Intraoperative pEEG has been implemented since July 2015. Participants having surgery after this time point had intraoperative pEEG applied before induction until full recovery. All related staff had been trained in the application of pEEG-guided anesthesia and the assessment of POD. Patients were screened twice daily for POD within 3 days after surgery by staff in the pain management team. In the first part of this study, we compared the incidence of POD and its trend from 2013 January-2015 July with 2015 July-2017 December. In the second part, we estimated odds ratios of risk factors for POD using multivariable logistic regression in case-control setting. RESULTS: The incidence of POD decreased from 1.18 to 0.41% after the administration of intraoperative pEEG. For the age group ⧠75 years, POD incidence decreased from 5.1 to 1.56%. Further analysis showed that patients with pEEG-guided anesthesia were associated with a lower odd of POD (aOR 0.33; 95% CI 0.18-0.60) than those without after adjusting for other covariates. CONCLUSIONS: Implementation of intraoperative pEEG was associated with a lower incidence of POD within 3 days after surgery, particularly in the elderly. Intraoperative pEEG might be reasonably considered as part of the strategy to prevent POD in the elder population. TRIAL REGISTRATION: Not applicable.

BACKGROUND: The efficacy of i.v. or topical lidocaine as an anaesthesia adjunct in improving clinical outcomes in patients receiving gastrointestinal endoscopic procedures under propofol sedation remains unclear. METHODS: Electronic databases (MEDLINE, EMBASE, and Cochrane Library) were searched for RCTs comparing the clinical outcomes with or without lidocaine application (i.v. or topical) in patients receiving propofol for gastrointestinal endoscopic procedures from inception to 29 March 2021. The primary outcome was propofol dosage, while secondary outcomes included procedure time, recovery time, adverse events (e.g. oxygen desaturation), post-procedural pain, and levels of endoscopist and patient satisfaction. RESULTS: Twelve trials (1707 patients) published between 2011 and 2020 demonstrated that addition of i.v. (n=7) or topical (n=5) lidocaine to propofol sedation decreased the level of post-procedural pain (standardised mean difference [SMD]=-0.47, 95% confidence interval [CI]: -0.8 to -0.14), risks of gag events (risk ratio [RR]=0.51, 95% CI: 0.35-0.75), and involuntary movement (RR=0.4, 95% CI: 0.16-0.96). Subgroup analysis demonstrated that only i.v. lidocaine reduced propofol dosage required for gastrointestinal endoscopic procedures (SMD=-0.83, 95% CI: -1.19 to -0.47), increased endoscopist satisfaction (SMD=0.75, 95% CI: 0.21-1.29), and shortened the recovery time (SMD=-0.83, 95% CI: -1.45 to -0.21). Intravenous or topical lidocaine did not affect the incidence of oxygen desaturation (RR=0.72, 95% CI: 0.41-1.24) or arterial hypotension (RR=0.6, 95% CI: 0.22-1.65) and procedure time (SMD=0.21, 95% CI: -0.09 to 0.51). CONCLUSION: This meta-analysis demonstrated that i.v. or topical lidocaine appears safe to use and may be of benefit for improving propofol sedation in patients undergoing gastrointestinal endoscopic procedures. Further large-scale trials are warranted to support our findings.

PURPOSE: This meta-analysis aimed to assess the impact of cricoid pressure (CP) application on intubation outcomes. SOURCE: Electronic databases (i.e., MEDLINE, PubMed, Embase, and Cochrane review) were searched from inception to 2 June 2020 for randomized-controlled trials that assessed the intubation outcomes in adult patients using laryngoscopic approaches with and without the application of CP (i.e., CP vs non-CP group). The primary outcome was the successful first-attempt intubation rate (SFAIR), and the secondary outcomes were intubation time, incidences of poor laryngoscopic views (i.e., Cormack and Lehane grade 3-4), airway complications, and pulmonary aspiration. PRINCIPAL FINDINGS: A total of five trials (published from 2005 to 2018) were included, and all tracheal intubations were performed by anesthesiologists or nurse anesthetists with a video (n = 3) or Macintosh laryngoscope (n = 2) in the operating room. We found no significant difference in SFAIR (risk ratio [RR], 0.98; P = 0.37), incidence of poor laryngoscopic views (RR, 1.49; P = 0.21), and risk of sore throat (RR, 1.17; P = 0.73) between the two groups. Nevertheless, the intubation time on the first successful attempt was slightly longer (weighted mean difference = 4.40 sec, P = 0.002) and risk of hoarseness was higher (RR, 1.70; P = 0.03) in the CP group compared with in the non-CP group. The secondary outcome "pulmonary aspiration" was not analyzed because only one trial was available. CONCLUSION: The application of CP did not have a negative impact on the SFAIR or laryngoscopic view. Nevertheless, this maneuver may slightly prolong intubation time and increase the risk of postoperative hoarseness.
RéSUMé: OBJECTIF : Cette méta-analyse a pour but d'évaluer l'impact de l'application d'une pression cricoïdienne (PC) sur les résultats de l'intubation. SOURCE : Les bases de données électroniques (c.-à-d., MEDLINE, PubMed, Embase, et Cochrane review) ont été examinées de leur création jusqu'au 2 juin 2020 pour en tirer les études randomisées contrôlées évaluant les résultats d'intubation chez les patients adultes utilisant des approches laryngoscopiques avec ou sans application de PC (soit groupe PC et non-PC). Le critère d'évaluation principal était le taux d'intubations réussies à la première tentative, et les critères secondaires incluaient le temps d'intubation, l'incidence de mauvaises vues laryngoscopies (grades 3-4 de Cormack et Lehane), les complications au niveau des voies aériennes et l'aspiration pulmonaire. CONSTATATIONS PRINCIPALES : Cinq études au total (publiées entre 2005 et 2018) ont été incluses, et toutes les intubations trachéales ont été réalisées par des anesthésiologistes ou infirmiers anesthésistes à l'aide d'un vidéolaryngoscope (n = 3) ou d'une lame de Macintosh (n = 2) en salle d'opération. Nous n'avons trouvé aucune différence significative dans le taux d'intubations réussies à la première tentative (risque relatif [RR], 0,98; P = 0,37), dans l'incidence de mauvaises vues laryngoscopiques (RR, 1,49; P = 0,21) ou dans le risque de maux de gorge (RR, 1,17; P = 0,73) entre les deux groupes. En revanche, le temps d'intubation lors de la première tentative réussie était légèrement plus long (différence moyenne pondérée = 4,40 sec, P = 0,002) et le risque d'enrouement était plus élevé (RR, 1,70; P = 0,03) dans le groupe PC que dans le groupe non-PC. Le critère d'évaluation secondaire « aspiration pulmonaire ¼ n'a pas été analysé parce qu'une seule étude le mesurait. CONCLUSION : L'application de PC n'a pas eu d'impact négatif sur le taux d'intubations réussies à la première tentative ou la vue laryngoscopique. Par contre, cette manÅuvre pourrait légèrement prolonger le temps d'intubation et augmenter le risque d'enrouement postopératoire.

BACKGROUND: Despite reported superior intubation outcomes associated with Parker Flex-Tip (PFT) tubes compared with those associated with standard polyvinylchloride tubes, the efficacy and safety of PFT tubes remain uncertain. OBJECTIVES: To compare the intubation outcomes between PFT and conventional standard polyvinylchloride tubes. DESIGN: Meta-analysis of randomised controlled trials. DATA SOURCES: Embase, Medline, Google Scholar, PubMed and the Cochrane controlled trials register from inception until 3 January 2021. ELIGIBILITY CRITERIA: All randomised trials comparing intubation outcomes between PFT (PFT group) and standard polyvinylchloride (standard polyvinylchloride group) tubes. RESULTS: Analysis of the 13 eligible trials showed no significant difference in successful first-attempt intubation rate [risk ratio (RR) 1.20, 95% confidence interval (CI) 0.99 to 1.44] (6 trials, 568 participants), trauma risk (RR 0.83, 95% CI 0.67 to 1.03) (5 trials, 501 participants) as well as the overall risks of epistaxis (RR 0.58, 95% CI 0.26 to 1.31) (3 trials, 262 participants), sore throat (RR 0.90, 95% CI 0.70 to 1.17) (4 trials, 451 participants) and hoarseness (RR 0.71, 95% CI 0.44 to 1.14) (4 trials, 451 participants) between the two groups. However, the intubation time was slightly shorter (weighted mean difference -4.2âs, 95% CI -7.4 to -1.0âs) (8 trials, 759 participants) and the risks of severe epistaxis (RR 0.15, 95% CI 0.03 to 0.84) (3 trials, 262 participants) and overall difficulty in airway manipulation (RR 0.48, 95% CI 0.29 to 0.80) (8 trials, 647 participants) were lower in the PFT group than those in the standard polyvinylchloride group. Trial sequential analysis conclusively confirmed a shorter intubation time with PFT tubes than with standard polyvinylchloride tubes, whereas other intubation outcomes were inconclusive. CONCLUSION: The use of PFT tubes for airway manipulation was associated with a shorter intubation time compared with the standard polyvinylchloride tubes. The results of trial sequential analysis suggest the need for further trials and meta-analysis to compare other intubation outcomes associated with the two devices.

BACKGROUND: The explanation of epidural analgesia by anesthesiologist would often begin after the parturient is admitted to the hospital. Because of labor pain, the decision of receiving epidural analgesia would often be made by the family members, instead of the parturient herself. We aimed to test whether earlier prenatal shared decision-making (SDM) interventions increase parturient's comprehension and satisfaction of epidural labor analgesia, compared to conventional explanation after labor pain begun. METHODS: During the 28th week of gestation, we provided the SDM parturient health education as well as a leaflet with quick response codes. Scanning the code would link to education videoclips which explained what epidural analgesia is and its advantages and disadvantages. Original routine practice group parturients received explanation of analgesia after admission for delivery. To measure the satisfaction of labor pain service, the accessibility of information, and the communication with medical staff, we designed a questionnaire with reference to (1) Pregnancy and Maternity Care Patients' Experiences Questionnaire (PreMaPEQ), (2) Preterm Birth Experience and Satisfaction Scale (P-BESS), and (3) Women's Views of Birth Labor Satisfaction Questionnaire (WOMBLSQ). The questionnaire was amended after a pretest involving 30 parturients who had received epidural analgesia. Scree test analysis and exploratory factor analysis were performed; then, the questionnaire was revised again. A total of 200 valid questionnaires were collected-100 each from the original routine practice group and the SDM group. RESULTS: The SDM group reported significantly higher satisfaction with and understanding of epidural analgesia, and a significantly higher satisfaction with the information received, and the quality of pain relief. After SDM intervention, significant increasement of the average satisfaction scores in question "my epidural is effective" (9.10%; mean difference: 0.38; 95% confidence interval, 0.17 ~ 0.59; p < 0.001) and "The effect of epidural is just as what I have expected" (10.41%; mean difference: 0.41; 95% confidence interval, 0.18 ~ 0.64; p < 0.001) was demonstrated. CONCLUSIONS: An earlier prenatal SDM intervention with sufficient information through videoclips increased parturients' comprehensions and satisfaction of epidural analgesia service.

BACKGROUND: Whether nonobstetric surgery during gestation is associated with a higher risk of spontaneous abortion or adverse delivery outcomes is still unclear. METHODS: We performed a retrospective case-control study using a Longitudinal Health Insurance Database (LHID 2000) containing claim-data of 1 million randomly selected beneficiaries. We compared the incidences and estimated the adjusted odds ratios (aOR) with 95% confidence interval (95% CI) for spontaneous abortion, adverse delivery outcomes, cesarean delivery, and prolonged hospital stay to determine the risk of adverse outcomes in women who had nonobstetric surgery during gestation as compared to those who did not have any surgery during gestation. RESULTS: After exclusion, we were left with 114,852 delivery and 3999 abortion cases in our study; and 462 (0.39%) of them had nonobstetric surgery under general or regional anesthesia during pregnancy. The leading surgeries were repair of cervical os (33.12%), appendectomy (17.32%), ovarian surgeries (13.64%), and fixation of fractured bone (8.01%).The risk of spontaneous abortion (4.23% vs. 2.43%, aOR:1.53; 95% CI: 1.01-2.31), antepartum hemorrhage (7.14% vs. 2.83%, aOR: 2.51; 95% CI: 1.74-3.61), pre-eclampsia/eclampsia (2.60% vs. 1.01%, aOR: 2.35; 95% CI: 1.30-4.23), gestational diabetes (2.38% vs. 0.69%, aOR: 3.12; 95% CI: 1.69-5.78), prematurity (9.06 vs. 4.90%, aOR: 3.31; 95% CI: 2.54-4.31), cesarean section (43.55% vs. 33.76%, aOR: 1.41; 95% CI: 1.17-1.71), and prolonged hospital stay (1.82% vs. 5.91%, aOR: 3.23; 95% CI: 2.16-4.83) were higher in those women who had nonobstetric surgery after adjusting for age and comorbidities. CONCLUSIONS: Nonobstetric surgery during gestation were associated with a higher risk of spontaneous abortion, adverse delivery outcomes, cesarean section, and prolonged hospital stay.

BACKGROUND: During pregnancy, the hyperdynamic physiology of circulation can exacerbate many cardiovascular disorders. Congestive heart failure (CHF) usually occurs during late pregnancy, which is significantly associated with a high level of maternal and neonatal morbidities and mortalities. The profile of women who develop peripartum CHF (PCHF) is unknown. We investigated the epidemiological profiles of PCHF. METHODS: In this retrospective cohort study, PCHF patients were identified using International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes in Taiwan's National Health Insurance Research Database. Risk factors and obstetric outcomes were compared in women with and without PCHF. RESULTS: From 2,115,873 birth-mothers in Taiwan between 1997 and 2013, we identified 512 with PCHF (incidence: 24.20/105). More women with than without PCHF were older (≥ 35, 18.16% vs. 9.62%), and had more multifetal gestations (7.42% vs. 1.40%), gestational hypertension (HTN) (19.2% vs. 1.31%), and gestational diabetes mellitus (4.10% vs. 0.67%). After the analysis had been adjusted for confounders, the leading comorbidities associated with PCHF were structural heart diseases (adjusted odds ratio [aOR]: 67.21; 95% confidence interval [CI]: 54.29-83.22), pulmonary diseases (aOR: 13.12; 95% CI: 10.28-16.75), chronic HTN (aOR: 11.27; 95% CI: 6.94-18.28), thyroid disease (aOR: 9.53; 95% CI: 5.27-17.23), and gestational HTN (aOR: 5.16; 95% CI: 3.89-6.85). PCHF patients also had a higher rate of cesarean sections (66.41% vs. 34.46%; p < 0.0001). CONCLUSION: Maternal structural heart diseases, pulmonary diseases, thyroid disorders, and preexisting or gestational HTN are associated with a higher risk of developing PCHF. Birth-mothers with PCHF also had a higher risk of caesarean section and adverse outcomes, including maternal death. Our findings should benefit healthcare providers, and government and health insurance policy makers.

BACKGROUND: Postoperative ileus (POI) is a complication that may occur after abdominal or nonabdominal surgery. Intravenous dexmedetomidine (Dex) has been reported to accelerate postoperative gastrointestinal function recovery; however, updated evidence is required to confirm its robustness. METHODS: To identify randomized controlled trials examining the effects of perioperative intravenous Dex on gastrointestinal function recovery in patients undergoing noncardiac surgery, databases including MEDLINE, EMBASE, Google Scholar, and Cochrane Library were searched on August 2023. The primary outcome was time to first flatus. Secondary outcomes included time to oral intake and defecation as well as postoperative pain scores, postoperative nausea/vomiting (PONV), risk of hemodynamic instability, and length of hospital stay (LOS). To confirm its robustness, subgroup analyses and trial sequential analysis were performed. RESULTS: The meta-analysis of 22 randomized controlled trials with 2566 patients showed that Dex significantly reduced the time to flatus [mean difference (MD):-7.19 h, P <0.00001), time to oral intake (MD: -6.44 h, P =0.001), time to defecation (MD:-13.84 h, P =0.008), LOS (MD:-1.08 days, P <0.0001), and PONV risk (risk ratio: 0.61, P <0.00001) without differences in hemodynamic stability and pain severity compared with the control group. Trial sequential analysis supported sufficient evidence favoring Dex for accelerating bowel function. Subgroup analyses confirmed the positive impact of Dex on the time to flatus across different surgical categories and sexes. However, this benefit has not been observed in studies conducted in regions outside China. CONCLUSIONS: Perioperative intravenous Dex may enhance postoperative gastrointestinal function recovery and reduce LOS, thereby validating its use in patients for whom postoperative ileus is a significant concern.

Background: Postoperative atrial fibrillation (POAF) is a frequent complication that may increase morbidity and mortality risk following cardiac surgery. The systemic immune-inflammation index (SII) is an emerging biomarker that provides an integrated measure of inflammation by incorporating neutrophil, lymphocyte, and platelet counts. Recent studies have reported associations between elevated SII and increased POAF risk; however, significant heterogeneity exists regarding its predictive efficacy. This meta-analysis aimed to assess SII's diagnostic efficacy for predicting POAF risk. Methods: To synthesize existing evidence on the ability of perioperative SII for predicting POAF in patients undergoing cardiac surgery, a systematic review and meta-analysis was conducted. In August 2023, a comprehensive literature search was performed to identify relevant studies reporting SII cutoff values with corresponding sensitivity and specificity. The primary aim was to evaluate SII's diagnostic utility for predicting POAF, whereas secondary outcomes included the pooled incidence of POAF and the relationship between the SII and POAF. Results: Eight studies published between 2021 and 2023 with 3,245 patients were included. Six studies involved coronary artery bypass grafting (CABG) surgery; one encompassed various cardiac procedures, and another focused solely on mitral valve surgery. The pooled incidence of POAF was 23.6% [95% confidence interval (CI), 18.7%-29.2%]. Elevated SII significantly increased the odds of POAF by 3.24-fold (odds ratio, 3.24; 95% CI, 1.6-6.55; p = 0.001). SII's pooled sensitivity and specificity for predicting POAF were 0.80 (95% CI, 0.68-0.89) and 0.53 (95% CI, 0.23-0.8), respectively. The SII had moderate predictive accuracy based on a hierarchical summary receiver operating characteristic (HSROC) area under the curve of 0.78 (95% CI, 0.74-0.81). Subgroup analyses, whether focusing on CABG alone or CABG with cardiopulmonary bypass (CPB), both indicated an area under the HSROC curve of 0.78 (95% CI, 0.74-0.81). Conclusion: Elevated SII is significantly correlated with an increased POAF risk following cardiac surgery, highlighting its utility as a predictive biomarker. Considering its moderate diagnostic accuracy, further research is essential for clarifying SII's clinical effectiveness, either as an independent predictor or combined with other risk factors, for stratifying patients at high POAF risk.

RESUMO
BACKGROUND: Postpartum depression is a major psychiatric disorder associated with maternal suicide and child developmental disturbances. In this study, we aimed to investigate whether general anesthesia for cesarean delivery is associated with a higher rate of new-onset depression after delivery than neuraxial anesthesia. METHODS: This is a nationwide retrospective cohort study using data retrieved from the National Health Insurance Research Database between 2014 and 2018. Women who had cesarean delivery under general or neuraxial anesthesia were enrolled. After 1:4 propensity score matching, there were 4544 and 18,176 women under the general and neuraxial anesthesia groups, respectively. The primary outcome was new-onset depression diagnosed after delivery in a time-to-event analysis setting. RESULTS: After propensity-score matching, the rate of new-onset depression diagnosed within 1 year was 1.10 % (50/4488) and 0.86 % (157/18176) after cesarean delivery under general and neuraxial anesthesia, respectively. For depression diagnosed within 90 days of delivery, significant difference between the two groups was noted (0.51 % vs. 0.30 %, P = 0.031). In the time-to-event analysis with Cox regression model, women who delivered under general anesthesia were associated with significantly higher risk of postpartum depression within 90 days (Hazard ratio [HR], 1.71; 95 % CI, 1.05-2.79) compared with those under neuraxial anesthesia. LIMITATIONS: The observational design only allows asserting association, rather than establishing causality between exposure and outcomes. CONCLUSIONS: Women who underwent cesarean delivery under general anesthesia had a higher risk of subsequent depression within 90 days than those under neuraxial anesthesia. Early screening for depressive disorders might facilitate timely management.
RESUMO
Background: This meta-analysis aimed to synthesize current evidence on the association between the Geriatric Nutritional Risk Index (GNRI) and long-term outcomes in patients undergoing hemodialysis. Methods: Electronic databases were systematically searched for relevant studies that investigated the association between GNRI and long-term outcomes in hemodialysis patients until November 2023. The primary outcome was the association between the GNRI (i.e., low versus high) and overall mortality risk, while the secondary outcome was the relationship between the GNRI and cardiovascular mortality risk. Results: Thirty cohort studies involving 55,864 patients were included. A low GNRI was found to be significantly associated with increased overall mortality (hazard ratio [HR]: 2.42, 95% confidence interval [CIs]: 2.10-2.79, p < 0.00001, I2 = 65%). Each unit increase in GNRI corresponded to a 5% reduction in mortality risk (HR: 0.95, 95% CI: 0.93-0.96, p < 0.00001, I2 = 79%). The association remained consistent across Asian (HR = 2.45, 95% CI: 2.08-2.88, p < 0.00001, I2 = 70%) and non-Asian subgroups (HR = 2.3, 95% CI: 1.72-3.06, p < 0.00001, I2 = 23%). Meta-regression analysis of patient age (coefficient: -0.002; p = 0.896), male proportion (coefficient: 0.002; p = 0.875), percentage of diabetes mellitus (coefficient: -0.003; p = 0.605), and follow-up duration (coefficient: -0.003; p = 0.431) revealed that these moderator variables did not significantly influence the association between GNRI and overall mortality risk. Cardiovascular mortality risk also increased with low GNRI (HR, 1.93; 95%CI: 1.51-2.45, p < 0.00001; I2 = 2%). Similarly, an inverse association was observed between the GNRI values and cardiovascular mortality risk (HR, 0.94; 95% CI: 0.91-0.97; p < 0.0001; I2 = 65%) (per unit increase). Conclusion: The GNRI is a simple nutritional screening tool that can be used to effectively stratify patients undergoing hemodialysis globally. Further studies are warranted to determine whether nutrition optimization based on the GNRI improves long-term outcomes.

RESUMO
Background: This meta-analysis aimed at investigating the efficacy of acupuncture for pain relief in patients receiving extracorporeal shock wave lithotripsy (ESWL). Methods: Randomized controlled trials comparing the efficacy of acupuncture with conventional treatments were retrieved from major electronic databases (e.g., MEDLINE, EMBASE, and Cochrane Library) until August 28, 2022. The primary outcome was the response rate (i.e., rate of pain relief), while secondary outcomes included stone-free rate, satisfaction rate, duration of ESWL, peri-/post-procedural pain score, and risk of adverse events. Results: Thirteen eligible studies involving 1,220 participants published between 1993 and 2022 were analyzed. Pooled results indicated that acupuncture had a better response rate compared to conventional treatments (RR = 1.17, 95% CI: 1.06-1.3, p = 0.003, seven trials, n = 832). Despite no difference in ESWL duration (MD = 0.02 min, 95% CI: -1.53 to 1.57, p = 0.98, three trials, n = 141), stone-free rate (RR = 1.11, 95% CI: 1-1.25, p = 0.06, six trials, n = 498), and satisfaction rate (RR = 1.51, 95% CI: 0.92-2.47, p = 0.1, three trials, n = 334) between the two groups, the acupuncture group had a lower risk of adverse events (RR = 0.51, 95% CI: 0.33-0.79, p = 0.003, five trials, n = 327), peri- (MD = -1.91 points, 94% CI: -3.53 to -0.28, p = 0.02, four trials, n = 258 patient) and post-procedural (MD = -1.07, 95% CI: -1.77 to -0.36, p = 0.003, four trials, n = 335) pain score. Conclusion: The results of this meta-analysis showed that the use of acupuncture in patients receiving ESWL was associated with a higher pain relief rate and a lower risk of adverse events, suggesting feasibility of its use in this clinical setting.

RESUMO
Background: Post-stroke depression (PSD) affects up to one-third of patients who survive stroke. This matched cohort study aimed to investigate the relationship between vitamin D deficiency (VDD) and PSD using a global health research network. Methods: Adult patients with first-ever stroke were eligible for inclusion if their circulating vitamin D levels were available within 3 months before the onset of stroke. Patients were subdivided into those with VDD [VDD group, 25(OH) D < 20 ng/mL] and those with normal vitamin D levels [control group, 25(OH) D: 30-80 ng/mL]. By using propensity score matching (PSM), potential confounding factors were adjusted. The primary outcomes were the association of VDD with the risk of PSD at the 3-month and 12-month follow-ups, while the secondary outcomes were the relationships between VDD and the risk of pneumonia as well as emergency department visits at the 12-month follow-up. Results: After PSM, 758 individuals were included in each group, with no significant differences in baseline characteristics. Musculoskeletal diseases, metabolic disorders, and hypertension were the three leading comorbidities in both the groups. The incidence of PSD was not significantly different between the two groups at the 3-month (5.8% vs. 4.7%, p = 0.358) and 12-month (11.6% vs. 10.2%, p = 0.364) follow-up. VDD was not associated with an increased risk of PSD at the 3-month [hazard ratio (HR) = 1.258, p = 0.358] or 12-month follow-up (HR = 1.210, p = 0.364). In addition, VDD was not associated with an increased risk of pneumonia (HR = 1.053, p = 0.823) or emergency visits at the 12-month follow-up (HR = 1.206, p = 0.148). Conclusion: The results revealed no significant link between VDD and PSD risk during the 3-month and 12-month follow-up periods, suggesting that VDD might not play a substantial role in PSD risk. However, further extensive studies employing a prospective design are necessary to explore the potential protective effects of vitamin D against PSD and validate these findings.
RESUMO
STUDY OBJECTIVE: This meta-analysis aimed at identifying the risk factors for and their strengths in predicting difficult mask ventilation (MV) through a systematic approach. DESIGN: Meta-analysis of observational studies. SETTING: Operating room. INTERVENTION: Airway- or patient-related risk factors for difficult MV reported in over 20% of eligible studies identified through literature review. PATIENTS: Adults receiving anesthetic induction with requirement of MV. MEASUREMENTS: Databases including EMBASE, MEDLINE, Google Scholar, and Cochrane Library were searched from inception to July 2022. The primary outcomes were the identification of commonly reported risk factors for MV and a comparison of their strengths in difficult MV prediction, while the secondary outcomes were the prevalence of difficult MV in the general population and those with obesity. MAIN RESULTS: Meta-analysis of 20 observational studies involving 335,846 patients identified 13 risk factors with predictive strengths (all p < 0.05): neck radiation (OR = 5.0, five studies, n = 277,843), increased neck circumference (OR = 4.04, 11 studies, n = 247,871), obstructive sleep apnea (OSA) (OR = 3.61, 12 studies, n = 331,255), presence of beard (OR = 3.35, 12 studies, n = 295,443), snoring (OR = 3.06, 14 studies, n = 296,105), obesity (OR = 2.99, 11 studies, n = 278,297), male gender (OR = 2.76, 16 studies, n = 320,512), Mallampati score III-IV (OR = 2.36, 17 studies, n = 335,016), limited mouth opening (OR = 2.18, six studies, n = 291,795), edentulous (OR = 2.12, 11 studies, n = 249,821), short thyroid-mental distance (OR = 2.12, six studies, n = 328,311), old age (OR = 2, 11 studies, n = 278,750), and limited neck movement (OR = 1.98, nine studies, n = 155,101). The prevalence of difficult MV was 6.1% (16 studies, n = 334,694) and 14.4% (four studies, n = 1152) in the general population and those with obesity, respectively. CONCLUSIONS: Our results demonstrated the strengths of 13 most common risk factors for predicting difficult MV, which may serve as an evidence-based reference for clinicians to incorporate into their daily practice.

LAY ABSTRACT: A previous meta-analysis has demonstrated a superior analgesic efficacy of epidural analgesia (e.g. labor epidural analgesia) in comparison with non-epidural approaches. The widely accepted safety of labor epidural analgesia also endorses its current popularity in obstetric practice. However, the results of a recent large-scale longitudinal study that demonstrated a significant increase in risk of autism spectrum disorder in offspring from mothers with labor epidural analgesia exposure have raised some concerns over the safety of its use. The current meta-analysis aimed at examining the strength of evidence regarding this issue based on updated clinical data. Through systematically reviewing seven eligible observational studies involving 4,021,406 children from electronic databases, our results showed a slight but statistically significant increase in risk of autism spectrum disorder in children with exposure to labor epidural analgesia compared with those without. The finding was consistent in subgroup analysis focusing on siblings and children delivered vaginally. Nevertheless, despite the tendency of an increased risk of autism spectrum disorder in children exposed to labor epidural analgesia <4 h, this effect was not observed in those exposed to labor epidural analgesia >8 h (data from two studies). In conclusion, the level of evidence linking labor epidural analgesia to autism spectrum disorder development in offspring was very low based on the latest data because of the small effect size and the finding of a lack of cumulative dose-response effect in the current analysis. Further studies are warranted to provide an insight into this issue.

Background: Although post-stroke depression (PSD) affects one-third of patients following an acute stroke, pooled evidence addressing the correlation between a low vitamin D status and the risk of PSD remains inconclusive. Methods: Comprehensive database search of Medline, EMBASE, Cochrane library, and Google Scholar was performed from inception to December 2022. The primary outcome was the association of PSD risk with a low vitamin D status, while the secondary outcomes included the relationship between PSD and other risk factors. Results: Analysis of seven observational studies published between 2014 and 2022 with 1,580 patients showed pooled incidences of vitamin D deficiency (defined as 25[OH] D levels < 50 nmol/L) and PSD of 60.1 and 26.1%, respectively. Patients with PSD had a lower circulating vitamin D concentration compared to those without [mean difference (MD) =-13.94 nmol/L, 95% CI: -21.83 to -6.05, p = 0.0005, I 2 = 91%, six studies, 1,414 patients]. Meta-analysis also demonstrated a correlation between a low vitamin D level and an increased PSD risk [odd ratio (OR) = 3.25, 95% CI: 1.57-6.69, p = 0.001, I 2 = 78.7%, 1,108 patients], the heterogeneity of which was found to be associated with the incidence of vitamin D deficiency but not female proportion on meta-regression. Besides, female gender (OR = 1.78, 95% CI: 1.3-2.44, p = 0.003, I 2 = 31%, five studies, 1,220 patients), hyperlipidemia (OR = 1.55, 95% CI: 1.01-2.36, p = 0.04, I 2 = 0%, four studies, 976 patients), and high National Institutes of Health Stroke Scale (NIHSS) scores (MD = 1.45, 95% CI: 0.58-2.32, p = 0.001, I 2 = 82%, five studies, 1,220 patients) were potential risk factors for PSD. For the primary outcome, the certainty of evidence was very low. Regarding secondary outcomes, the certainty of evidence was low for BMI, female gender, hypertension, diabetes, and stroke history, and very low for age, level of education, hyperlipidemia, cardiovascular disease, and NIHSS scores. Conclusion: The results suggested an association of a low circulating vitamin D level with an increased risk of PSD. Besides, female gender, hyperlipidemia, high NIHSS score were related to an increased risk or occurrence of PSD. The current study may imply the necessity of routine circulating vitamin D screening in this population.

RESUMO
Background: Although prognostic nutritional index (PNI) has been frequently applied in patients with malignancy or those during postoperative recovery, whether it is also an optimal indicator of the risk of contrast-induced nephropathy (CIN) in patients receiving coronary angiography remains uncertain. This meta-analysis aimed at investigating the clinical association of PNI with the risk of CIN in patients receiving coronary angiography or percutaneous coronary intervention. Methods: Embase, Medline, Cochrane Library, and Google scholar were searched for studies until January 2023. The relationship between CIN risk and PNI (i.e., low vs. high) (primary outcome) as well as other variables (secondary outcomes) were analyzed using a random-effects model. Results: Overall, 10 observational studies with 17,590 patients (pooled incidence of CIN: 18%) were eligible for analysis. There was a higher risk of CIN in patients with a low PNI compared to those with a high PNI [odd ratio (OR) = 3.362, 95% confidence interval (CI): 2.054 to 5.505, p < 0.0001, I 2 = 89.6%, seven studies, 12,972 patients, certainty of evidence: very low]. Consistently, a lower PNI was noted in patients with CIN compared to those without (Mean difference = -5.1, 95% CI: -6.87 to -3.33, p < 0.00001, I 2 = 96%, eight studies, 15,516 patients, certainty of evidence: very low). Other risks of CIN included diabetes and hypertension, while male gender and the use of statins were associated with a lower risk of CIN. Patients with CIN were older, had a higher creatinine level, and received a higher contrast volume compared to those without. On the other hand, pre-procedural albumin, estimated glomerular filtration rate, ejection fraction, hemoglobin, lymphocyte ratio were found to be lower in patients with CIN than in those without. Conclusion: This meta-analysis highlighted an inverse association of PNI with the risk of CIN, which required further studies for verification.

RESUMO
The use of ultrasonography to predict spinal-induced hypotension (SIH) has gained significant attention. This diagnostic meta-analysis aimed to investigate the reliability of the inferior vena cava collapsibility index (IVCCI) in predicting SIH in patients undergoing various surgeries. Databases, including Embase, Cochrane Library, Medline, and Google Scholar, were screened until 28 July 2023, yielding 12 studies with 1076 patients (age range: 25.6-79 years) undergoing cesarean section (CS) (n = 4) or non-CS surgeries (n = 8). Patients with SIH had a significantly higher IVCCI than those without SIH (mean difference: 11.12%, 95% confidence interval (CI): 7.83-14.41). The pooled incidence rate of SIH was 40.5%. IVCCI demonstrated satisfactory overall diagnostic reliability (sensitivity, 77%; specificity, 82%). The pooled area under the curve (AUC) was 0.85, indicating its high capability to differentiate patients at risk of PSH. The Fagan nomogram plot demonstrated a positive likelihood ratio (PLR) of 4 and a negative likelihood ratio (NLR) of 0.28. The results underscore the robustness and discriminative ability of IVCCI as a predictive tool for SIH. Nevertheless, future investigations should focus on assessing its applicability to high-risk patients and exploring the potential enhancement in patient safety through its incorporation into clinical practice.
RESUMO
The predictive value of the prognostic nutritional index (PNI) for the long-term prognosis of patients with acute coronary syndrome (ACS) remains uncertain. Medline, Embase, Cochrane Library, and Google Scholar were searched from inception until January 2023 to study the relationship between all-cause mortality risk and PNI in patients receiving percutaneous coronary intervention for ACS (i.e., primary outcome). Thirteen observational studies were included in this meta-analysis. Analysis of seven studies using PNI as a categorical variable showed a pooled hazard ratio (HR) of all-cause mortality of 2.97 (95% CI 1.65 to 5.34, p = 0.0003, I2 = 89%, n = 11,245) for patients with a low PNI. The meta-analysis also showed a higher risk of major adverse cardiovascular events (MACEs) in patients with a low PNI (HR 2.04; 95% CI 1.59 to 2.61; p < 0.00001; I2 = 21%; n = 8534). Moreover, advanced age, diabetes mellitus, and high Global Registry of Acute Coronary Events risk scores were associated with a high risk of all-cause mortality, whereas a high body mass index was associated with a low risk of all-cause mortality. The results showed an association between a low PNI and an increased risk of long-term mortality in patients undergoing coronary interventions for ACS. Further randomized controlled trials are necessary to confirm these findings.
