Effects of Dexamethasone on Post-Operative Cognitive Dysfunction and Delirium in Adults Following General Anaesthesia: A Meta-Analysis of Randomised Controlled Trials

Abstract Background Several studies have investigated the effects of dexamethasone on postoperative cognitive dysfunction (POCD) or postoperative delirium (POD); however, their conclusions have not been consistent. So we conducted a meta-analysis to determine the effects of dexamethasone on POCD/POD in adults following general anesthesia. Methods Cochrane Central Register of Controlled Trials (CENTRAL, 2018, Issue 11 of 12) in the Cochrane Library (searched November 17, 2018); MEDLINE OvidSP (1946 to November 16, 2018); and Embase OvidSP (1974 to November 16, 2018) were searched for randomized controlled trials that evaluated the incidence of POCD/POD following dexamethasone administration, in adults (age ≥18 years) under general anesthesia. We used the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) framework to assess the quality of evidence. Results Five studies were included (three studies/855 participants in dexamethasone group and 538 participants in placebo group for the incidence of POCD, and two studies/410 participants in dexamethasone group and 420 participants in placebo group for the incidence of POD). There was no significant difference between the dexamethasone group and the placebo group in terms of the incidence of POCD in 30 days after surgery (RR 1.00; 95% CI [0.51, 1.96], P = 1.00, I2 = 77%) or in the incidence of POD (RR 0.96; 95% CI [0.68, 1.35], P = 0.80, I2 = 0%). However, both analyses had some limitations since evidence remains limited and clinical heterogeneity, and we considered the quality of the evidence for the postoperative incidence of POCD and POD to be very low. Conclusions This meta-analysis revealed that prophylactic dexamethasone did not reduce the incidence of POCD and POD. Trials of alternative prevent strategies for POCD/POD, and a better understanding of the pathophysiology of those complex syndrome, are still needed to make progress of this field. Trial registration number: This study is registered with PROSPERO, 23 October 2018, number CRD42018114552.

However, both analyses had some limitations, and we considered the quality of the evidence for the postoperative incidence of POCD and POD to be very low. Conclusions This meta-analysis revealed that prophylactic dexamethasone did not reduce the incidence of POCD and POD. However, additional large high-quality trials are still needed to determine the effects of dexamethasone on the incidence of POCD/POD in patients undergoing surgery.

ObjectivesThe aim of this study was to investigate the efficacy, tolerability, safety, and impact on quality of life (QoL) and functional status of vortioxetine treatment for patients with generalised anxiety disorder (GAD) by performing a meta-analysis of randomised controlled trials (RCTs).DesignSystematic review and meta-analysis.Data sourcesData mining was conducted in January 2019 across PubMed, EMBASE, PsycINFO, Cochrane Central Register of Controlled Trials Cochrane Library, Web of science and ClinicalTrials.gov.Eligibility criteria for selecting studiesAll published RCTs, which assessed the effect of vortioxetine treatment for patients with GAD when compared with a placebo group, were included.Data extraction and synthesisRelevant data were extracted and synthesised narratively. Results were expressed as standardised mean differences or ORs with 95% CIs.ResultsOur meta-analysis showed that multiple doses (2.5, 5 and 10 mg/day) of vortioxetine did not significantly improve the response rates, compared with placebo (OR 1.16, 95% CI 0.84 to 1.60, p=0.38; OR 1.41, 95% CI 0.82 to 2.41, p=0.21; and OR 1.05, 95% CI 0.76 to 1.46, p=0.75). Moreover, there was no statistically significant difference regarding the remission rates, discontinuation for any reason rates, discontinuation due to adverse events rates, Short-Form 36 Health Survey scores or Sheehan Disability Scale scores between administration of multiple doses (2.5, 5 and 10 mg/day) of vortioxetine and placebo.ConclusionsAlthough our results suggest that vortioxetine did not improve the GAD symptoms, QoL and functional status impairment of patients with GAD, it was safe and well tolerated. Clinicians should interpret and translate our data with caution, as the meta-analysis was based on a limited number of RCTs.

Objective. The aim of this meta-analysis is to evaluate the effects of dexmedetomidine on intraocular pressure (IOP) in patients with general anesthesia administered via intubation. Methods. We searched randomized controlled trials (RCT) on the effects of intravenous injection of dexmedetomidine on IOP in patients with general anesthesia administered via intubation. Results. The meta-analysis study showed that (1) a statistically significant difference [WMD = −3.40 mmHg, 95% CI (−4.76, −2.04), P<0.00001] was found between IOP of the two groups. (2) The IOP of the dexmedetomidine group that was administrated succinylcholine was lower than that of placebo group which was administrated succinylcholine [WMD = −4.13 mmHg, 95% CI (−6.01, −2.25), P<0.0001]. (3) Compared with the IOP of patients in the placebo group, patients with intubation in the dexmedetomidine group maintained a lower IOP [WMD = −3.10 mmHg, 95% CI (−5.12, −1.07), P=0.003]. However, for incidences of bradycardia, the use of dexmedetomidine was higher than that of the placebo [RR = 0.23, 95% CI (0.07, 0.76), P=0.02]. Conclusion. This meta-analysis showed that, in many cases, dexmedetomidine can lower the IOP of patients with general anesthesia administered by intubation.

Abstract Background: The efficacy of interventions for elderly patients with sarcopenia has received increasing attention. Exercise and nutrition have been recognized as effective treatments for sarcopenia in many studies. However, evidence-based support from relevant studies is still lacking. Methods: The PubMed, Embase, Cochrane Library, VIP, CNKI, and SinoMed databases were searched. The basis for the diagnosis of sarcopenia, general condition of the subjects, duration and methods of exercise/nutritional therapy, outcome indicators, and quality of evidence were evaluated, and a meta-analysis of differences in treatment outcomes between the groups from baseline to the end of each study was conducted. Results: A total of 1860 papers were screened, including six randomized controlled trials, and the effects of protein intervention under exercise conditions on muscle mass, strength, and function in elderly patients with sarcopenia were investigated. The results showed that protein supplementation under resistance exercise conditions had the following effects on elderly patients with sarcopenia: there was a significant difference in knee flexion and extension strength (p = 0.02), grip strength (p = 0.02), fat mass (p = 0.04), and normal pace and pace (p = 0.0008 and p = 0.0010, respectively) between the intervention group and baseline data.Conclusion: The meta-analysis revealed some positive effects of protein intervention treatment under exercise conditions on elderly patients with sarcopenia. However, the quality of evidence is low. High-quality randomized controlled trials should be conducted in the future to provide a better clinical basis. Keywords: Sarcopenia, Exercise, Proteins

IntroductionBreathlessness in advanced cancer, a frequent multicomponent and debilitating disorder, severely reduces function and quality of patients’ life. Multiple studies have shown that non-pharmacological therapies can effectively palliate breathlessness in advanced cancer. However, no systematic review has investigated the application of acupuncture, as a non-pharmacological treatment, for breathlessness in advanced cancer. A systematic review will be conducted to summarise evidence supporting the efficacy and safety of acupuncture as a therapeutic option for breathlessness in advanced cancer based on existing randomised controlled trials (RCTs).MethodsRCTs will be retrieved from nine scientific databases, including the MEDLINE via PubMed, Web of Science via the Web of Knowledge, Embase via Ovid, the Cochrane Central Register of Controlled Trials via the Cochrane Library, and Allied and Complementary Medicine Database via EBSCO, China National Knowledge Infrastructure, Wanfang Database, VIP Database, Chinese Biomedical Literature Database; three clinical registry platforms, including the WHO International Clinical Trials Registry Platform, NIH Clinical trials.gov and Chinese Clinical Trial Registry, as well as from other sources. Studies published since inception of these databases to 1 August 2021 will be retrieved. Search terms will include breathlessness, cancer, acupuncture and RCT. Two investigators will independently select and extract data from RCTs and assess the risk of bias. The primary outcome, which is alleviation of breathlessness, will be assessed. Meta-analysis will be performed using RevMan V.5.4 and STATA V.15.0. The TSA 0.9.5.10 β software will be used to conduct trial sequential analysis. Finally, the quality of evidence from RCTs will be assessed using the Grading of Recommendations Assessment, Development and Evaluation System tool.Ethics and disseminationResults will be disseminated through peer-reviewed journals or conference reports. Since this study involves acquisition of secondary data, ethical approval requirements will be waived.PROSPERO registration numberCRD42021240085.

Abstract Background Irinotecan (IRI) and oxaliplatin (Ox) are standard therapeutic agents of the first-line treatments for metastatic colorectal cancer (mCRC). Previous meta-analyses of randomized controlled trials (RCTs) showed that treatment with Ox-based compared with IRI-based regimens was associated with better overall survival (OS). However, these reports did not include trials of molecular targeting agents and did not take methods for the administration of concomitant drugs, such as bolus or continuous infusion of 5-fluorouracil, into account. A systematic literature review was performed to compare the efficacy and toxicity profiles between IRI- and Ox-based regimens as the first-line treatments for mCRC. Methods This meta-analysis used data from the Cochrane Central Register of Controlled Trials, PubMed, and SCOPUS. The primary endpoint was OS, and the secondary endpoints were progression-free survival (PFS), objective response rate (ORR), and adverse events (AEs). Results Nineteen trials involving 4571 patients were included in the analysis. No statistically significant difference was observed between the two groups in terms of OS, PFS, and ORR. There was no significant heterogeneity. Regarding ≥ grade 3 AEs, IRI-based regimens were associated with a high incidence of leukopenia, febrile neutropenia, and diarrhea. Moreover, there was a high incidence of thrombocytopenia and peripheral sensory neuropathy in patients who received Ox-based regimens. In a subgroup analysis, IRI combined with bevacizumab was correlated with a better PFS (HR = 0.90, 95% CI = 0.82–0.98, P = 0.02), but not with OS (pooled HR = 0.91, 95% CI = 0.80–1.03, P = 0.15). Conclusion Although the safety profiles of IRI- and Ox-based regimens varied, their efficacy did not significantly differ. The combination of anti-VEGF antibody and IRI was associated with better PFS compared with anti-VEGF antibody and Ox. Both regimens could be used as the first-line treatments for mCRC with consideration of the patients’ condition or toxicity profiles.

<p>Posterior pedicle screw fixation has become a popular method for treating thoracolumbar burst fractures. However, it remains unclear whether additional fixation of more segments could improve clinical and radiological outcomes. This meta-analysis was performed to evaluate the effectiveness of fixation levels with pedicle screw fixation for thoracolumbar burst fractures. MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, Springer, and Google Scholar were searched for relevant randomized and quasirandomized controlled trials that compared the clinical and radiological efficacy of short versus long segment for thoracolumbar burst fractures managed by posterior pedicle screw fixation. Risk of bias in included studies was assessed using the Cochrane Risk of Bias tool. Based on predefined inclusion criteria, Nine eligible trials with a total of 365 patients were included in this meta-analysis. Results were expressed as risk difference for dichotomous outcomes and standard mean difference for continuous outcomes with 95% confidence interval. Baseline characteristics were similar between the short and long segment fixation groups. No significant difference was identified between the two groups regarding radiological outcome, functional outcome, neurologic improvement, and implant failure rate. The results of this meta-analysis suggested that extension of fixation was not necessary when thoracolumbar burst fracture was treated by posterior pedicle screw fixation. More randomized controlled trials with high quality are still needed in the future.</p>

Background. A substantial proportion of patients undergoing colorectal surgery receive a temporary stoma, and the timing for stoma closure remains unclear. The aim of this study was to evaluate the safety and feasibility of early stoma closure (ESC) compared with routine stoma closure (RSC) after colorectal surgery. Methods. We comprehensively searched PubMed, Embase, and the Cochrane Library for randomized controlled trials that compared ESC and RSC after colorectal surgery. Results. A total of 7 randomized controlled trials with 814 enrolled patients were identified for this meta-analysis. There were no significant differences between the ESC and RSC groups regarding the complications of stoma closure (26.8% and 16.6%, respectively; odds ratio [OR]: 1.30; 95% confidence interval [CI]: 0.89-1.90; P = .17). A subgroup analysis was conducted by Clavien-Dindo grade of complication, and no significant difference was observed in any subgroup ( P > .05). However, the ESC group had a significantly higher risk of wound complications than the RSC group (17.6% and 7.8%, respectively; OR: 2.61; 95% CI: 1.43-4.76; P = .002), and the RSC group had more cases of small bowel obstruction than the ESC group (3.1% and 8.4%, respectively; OR: 0.37; 95% CI: 0.15-0.87; P = .02). Conclusions. ESC is a safe and effective therapeutic approach in patients who have undergone colorectal surgery; it is associated with a reduced risk of bowel obstruction but a higher risk of wound complications.
