Abstract OBJECTIVES According to retrospective studies, oesophageal carcinoma is the second deadliest gastrointestinal cancer after gastric cancer. Enteral immunonutrition (EIN) has been increasingly used to enhance host immunity and relieve the inflammatory response of patients undergoing oesophagectomy; however, conclusions across studies remain unclear. We aimed to evaluate the effect of EIN on the clinical and immunological outcomes of patients undergoing oesophagectomy. METHODS Four electronic databases (MEDLINE, Embase, Web of Science and Cochrane Library) were used to search articles in peer-reviewed, English-language journals. The mean difference, relative risk or standard mean difference with 95% confidence interval were calculated. Heterogeneity was assessed by the Cochran’s Q test and I2 statistic combined with the corresponding P-value. The analysis was carried out with RevMan 5.3. RESULTS Six articles were finally included, with a total of 320 patients with oesophageal cancer. The meta-analysis results showed that EIN did not improve clinical outcomes (such as infectious complications, pneumonia, surgical site infection, anastomotic leak and postoperative hospital stay) or immune indices [referring to C-reactive protein, interleukin (IL)-6, IL-8, tumour necrosis factor-α]. Descriptive analysis suggested that EIN also increased the serum concentrations of IgG and the percentage of the B-cell fraction. Thus, its impact on IL-8 and IL-6 remains inconsistent. CONCLUSIONS The early-stage impact of EIN on immunological status in patients undergoing oesophagectomy is still unclear. According to the results of this meta-analysis, whether EIN could improve the clinical outcomes or biological status after oesophagectomy compared to standard enteral nutrition is uncertain. Since the impact of EIN is unclear, current guidelines that strongly advise the use of EIN should be changed, as the utility of EIN is very uncertain. More appropriately powered clinical studies are warranted to confirm its effectiveness.

Abstract BACKGROUND Although meningiomas are among the most prevalent types of brain tumors, AMs account for around 4% of all meningiomas. AMs tend to be more aggressive with relatively higher rates of recurrence and mortality. Gross total resection (GTR) has been the standard of care when possible. However, GTR itself is not always enough to prevent the recurrence of AMs. The role of PORT remains controversial in AM as the comparative studies to support its use have provided conflicting RESULTS: The purpose of this meta-analysis is to evaluate the impact of PORT on clinical outcomes according to the extent of resection in AMs. METHODS A review of the medical literature was conducted using online databases. Inclusion criteria consisted of AM diagnosis, English language, Simpson graded resections, and comparative studies reporting recurrence rates (RcR), Progression-Free Survival (PFS), and Overall Survival (OS) with hazard ratios (HR) or Kaplan-Meier curves. A meta-analysis was conducted using an inverse variance method with a random-effects model. RESULTS Twenty-two comparative studies with a total of 5,129 patients were included and analyzed. When GTR was attained, PORT was associated with improved RcR (HR =0.72, 95%CI:0.59-0.86) and PFS (HR=0.77, 95%CI:0.65-0.90), but not OS (HR=0.93, 95%CI:0.83-1.04). When subtotal resection (STR) was attained, PORT was associated with improved PFS (HR=0.35, 95%CI:0.26-0.48) as well as OS (HR=0.70, 95%CI:0.54-0.89). The extent of surgery also impacted AM outcomes as GTR demonstrated superior PFS (HR=0.45, 95%CI:0.31-0.65) and OS (HR=0.30, 95%CI:0.13-0.72). CONCLUSIONS This is the first meta-analysis to show that PORT is associated with PFS benefit in AMs with GTR and STR. Moreover, PORT significantly improved OS of AMs that underwent STR but had no impact on OS when GTR was achieved. In the absence of randomized clinical trials, this meta-analysis represents the most compelling data supporting the use of PORT in this patient population.

Objective To determine the impact of treatment for patients with nasal obstruction secondary to allergic rhinitis (AR) and nasal septal deviation (NSD) on sleep quality. Data Sources Primary studies were identified though PubMed, Scopus, Cochrane Library, and Web of Science. Review Methods A systematic review was performed by querying databases for articles published through August 2020. Studies were included that reported on objective sleep parameters (apnea-hypopnea index) and sinonasal and sleep-specific patient-reported outcome measures: Rhinoconjunctivitis Quality of Life Questionnaire, Nasal Obstruction Symptom Evaluation, Epworth Sleepiness Scale (EpSS), and Pittsburgh Sleep Quality Index (PSQI). Results The database search yielded 1414 unique articles, of which 28 AR and 7 NSD studies were utilized for meta-analysis. A total of 9037 patients (8515 with AR, 522 with NSD) were identified with a mean age of 35.0 years (35.3 for AR, 34.0 for NSD). Treatment for AR and NSD significantly improved subjective sleep quality. For AR, the EpSS mean difference was −1.5 (95% CI, –2.4 to –0.5; P = .002) and for the PSQI, –1.7 (95% CI, –2.1 to –1.2; P < .00001). For NSD, the EpSS mean difference was −3.2 (95% CI, –4.2 to –2.2; P < .00001) and for the PSQI, –3.4 (95% CI, –6.1 to –0.6; P = .02). Conclusion Subjective sleep quality significantly improved following treatment for AR and NSD. There were insufficient data to demonstrate that objective metrics of sleep quality similarly improved.

Digital Biomarkers

BACKGROUND Digital biomarkers are defined as objective, quantifiable physiological and behavioral data that are collected and measured by means of digital devices such as portables, wearables, implantables or digestibles. For their widespread adoption in publicly financed healthcare systems, it is important to understand how their benefits translate into improved patient outcomes, which is essential for demonstrating their value. OBJECTIVE To assess the quality and strength of evidence of the impact of digital biomarkers on clinical outcomes compared to interventions without digital biomarkers, reported in systematic reviews. METHODS A comprehensive search for 2019-2020 will be conducted in the PubMed and the Cochrane Library using keywords related to digital biomarkers and a filter for systematic reviews. Original full-text English publications of systematic reviews comparing clinical outcomes of interventions with and without digital biomarkers via meta-analysis will be included. The AMSTAR-2 tool will be used to assess the methodological quality of reviews. To assess the quality of evidence, we will evaluate systematic reviews using the GRADE tool. To detect the possible presence of reporting bias, we will record whether the protocol of the systematic reviews was published before the start of the study. A qualitative summary of results by digital biomarker technology and outcome will be provided. RESULTS This protocol was submitted before data collection. The next steps in this review will be initiated after the protocol is accepted for publication. CONCLUSIONS Our study will provide a comprehensive summary of the highest level of evidence available on digital biomarker interventions. Our results will help identify clinical areas where the use of digital biomarkers leads to favorable clinical outcomes. In addition, our findings will highlight areas of evidence gaps where the clinical benefits of digital biomarkers have not yet been demonstrated.

Background. This meta-analysis aimed to evaluate the efficacy and safety of Javanica oil emulsion injection (JOI) combined with chemotherapy versus chemotherapy in patients with advanced non-small-cell lung cancer (NSCLC). Methods. Electronic databases including EMBASE, PUBMED, the Cochrane library, and Chinese Biological Medical disc (CBM) were searched until May 2018. The clinical trials reporting efficacy and immune function of JOI combined with chemotherapy versus chemotherapy in advanced NSCLC were included according to the inclusion and exclusion criteria. Stata 11 and RevMan 5.3 were used for meta-analysis. Results. Twenty-four studies involving 2089 cases were included. The results of the meta-analysis showed that there were significant differences in objective response rate (risk ratio (RR) = 1.17; 95% confidence interval (CI): 1.05–1.29; P<0.05), improvement in Karnofsky Performance Status (standard mean difference (SMD) = 1.59; 95% CI: 1.41–1.77; P<0.01), incidence of adverse events (RR = 0.78; 95% CI: 0.7–0.87; P<0.05), percentage changes of CD3+ cells (SMD = 2.0; 95% CI: 1.49–2.50; P<0.01), CD4+ cells (SMD = 1.55; 95% CI, 1.2–1.9; P<0.01), natural killer cells (SMD = 1.98; 95% CI: 1.15–2.82; P<0.01), but not CD8+ (SMD = −1.44; 95% CI: −4.53–1.65; P=0.36), and value of CD4+/CD8+ (SMD = 0.32; 95% CI: 0.28–0.36; P<0.01) between the JOI combination group and control group. Funnel plot and Begg’s and Egger’s analysis indicated that there was no significant publication bias (P>0.05). Conclusions. JOI may be effective to improve the efficacy of chemotherapy in advanced NSCLC patients, accompanied with better levels of immune cells.

150 Background: Nearly 50% of men diagnosed with prostate cancer may receive treatment with some form of androgen deprivation therapy (ADT). While some side effects of ADT are well acknowledged, the specific impact of ADT on cognitive function is uncertain. Our objective was to perform a systematic review and meta-analysis assessing the impact of ADT on overall cognitive decline, and the risks of Alzheimers, Parkinson’s disease. Methods: Relevant studies were identified through search of English language articles indexed in PubMed Medline, PsycINFO, Cochrane Library and Web of Knowledge/Science. First, we assessed rates of cognitive decline in five cohorts from three studies. Second, we assessed rates of Alzheimer’s or Parkinson disease using three large retrospective studies. A pooled-analysis was conducted using a meta-analysis. Weighted averages were reported as odds ratios (OR) with 95% confidence intervals (CI) using RevMan and a DerSimonian and Laird random-effects model. The heterogeneity test was measured using the Q-Mantel-Haenszel ( P< 0.10 was considered of significant heterogeneity). Results: With respect to overall cognitive decline (defined as scoring 1.5 standard deviations [SD] in two or more objective cognitive tests), patients receiving ADT had higher odds of overall cognitive decline than patients with prostate cancer not treated with ADT or health controls (OR: 2.03, 95% CI: 1.42–2.90). Furthermore, men with a history of ADT for prostate cancer had higher odds of developing Alzheimer’s and Parkinson dementia compared to men with prostate cancer not treated with ADT (OR: 1.32, 95% CI: 1.27–1.37). Conclusions: Men receiving ADT for prostate cancer performed significantly worse on measures of overall cognitive function. Additionally, results from the three large observational trials included suggest men exposed to ADT for prostate cancer have higher rates of Parkinson/Alzheimer’s compared to men without ADT.

Objectives: ncluding stroke. The aim of this study was to systematically review the clinical evidence of CT for stroke.Methods: To identify randomized controlled trials (RCTs) reporting the effectiveness and/or safety of CT, seven databases including PubMed, EMBASE, and Cochrane Library were searched for articles published from January 2000 to February 2021 without language restrictions. Meta-analysis was performed using Review Manager 5.4 software and the results were presented as mean difference (MD) or standard mean difference (SMD) for continuous variables and odds ratio (OR) for diverse variables with 95% confidence intervals (CIs). Assessment of the methodological quality of the eligible trials was conducted using the Cochrane Collaboration tool for risk of bias in RCTs.Results: Twenty-two RCTs with 1653 participants were included in the final analysis. CT provided additional benefit in improving upper limb motor function (Fugl-Meyer assessment for upper limb motor function, MD 6.91, 95% CI 4.64 to 1.67, P<0.00001) and spasticity (response rate, OR 3.28, 95% CI 1.31 to 8.22, P=0.08) in stroke survivors receiving conventional medical treatment. These findings were supported with a moderate level of evidence. CT did not significantly increase the occurrence of adverse events.Conclusions: This study demonstrated the potential of CT to be beneficial in managing a variety of complications in stroke survivors. However, to compensate for the shortcomings of the existing evidence, rigorously designed large-scale RCTs are warranted in the future.

SUMMARY Changes in the structure of surgical training have affected trainees’ operative experience. Performing an esophagectomy is being increasingly viewed as a complex technical skill attained after completion of the routine training pathway. This systematic review aimed to identify all studies analyzing the impact of trainee involvement in esophagectomy on clinical outcomes. A search of the major reference databases (Cochrane Library, MEDLINE, EMBASE) was performed with no time limits up to the date of the search (November 2017). Results were screened in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, and study quality assessed using the MINORS (Methodological Index for Non-Randomized Studies) criteria. Four studies that included a total of 42 trainees and 16 consultants were identified, which assessed trainee involvement in open esophagogastric resectional surgery. A total of 1109 patients underwent upper gastrointestinal procedures, of whom 904 patients underwent an esophagectomy. Preoperative characteristics, histology, neoadjuvant treatment, and overall length of hospital stay were comparable between groups. One study found higher rates of anastomotic leaks in procedures primarily performed by trainees as compared to consultants (P &lt; 0.01)—this did not affect overall morbidity or survival; however, overall anastomotic leak rates from the published data were 10.4% (trainee) versus 6.3% (trainer) (P = 0.10). A meta-analysis could not be performed due to the heterogeneity of data. The median MINORS score for the included studies was 13 (range 11–15). This study demonstrates that training can be achieved with excellent results in high-volume centers. This has important implications on the consent process and training delivered, as patients wish to be aware of the risks involved with surgery and can be reassured that appropriately supervised trainee involvement will not adversely affect outcomes.

Background: The purpose of this study was to explore the ability of nonpharmacologic adjuvant interventions to alleviate pain in male patients during flexible cystoscopy (FC) under local anesthesia. Methods: Electronic databases including PubMed, the Cochrane Library, and Embase were searched to identify eligible clinical trials from inception to 31 December 2020, with no language restrictions. Two independent reviewers used Cochrane Collaboration tools to assess the selection criteria, methodological rigor and risk of bias. Statistical analyses were performed using STATA 14.2. Results: In total, 717 studies were initially identified, and fourteen randomized controlled trials were ultimately included. We observed that patients who underwent FC with higher irrigation pressures had significantly lower pain scores on the visual analog scale than their counterparts with lower irrigation pressure during FC (weight mean difference (WMD): −1.43; 95% confidence interval (CI): −1.72 to −1.14) with no between-study heterogeneity (p = 0.661). There were no significant differences in pain between immediate or delayed FC groups under the same local anesthetic (standard mean difference (SMD): −0.19; 95% CI: −0.39 to 0.01). A pooled analysis of three studies including 340 male patients showed that men who observed the cystoscopy on the monitor had significantly lower pain ratings compared to those who did not view the operation on the monitor (SMD: −0.64; 95% CI: −1.14 to −0.15). Two studies, including a total of 272 patients, assessed the influence of listening to music on pain and anxiety in male patients during FC. Our meta-analysis found that music significantly improved patient pain (WMD: −0.92; 95% CI: −1.29 to −0.54). Hand-holding and urination during FC also relieved pain and anxiety in male patients undergoing FC. Conclusions: We observed that elevated irrigation pressure, real-time cystoscopy visualization, and music therapy alleviated pain in male patients undergoing FC. Well-designed trials are needed to confirm our findings.

Abstract Introduction Postoperative pain is a significant problem that can lead to a range of complications including inadequate healing. Music has been shown to reduce postoperative pain across a range of surgical disciplines. This poster is novel as intra-operative awareness is an area of some debate and there has not previously been a systematic review of the impact of intraoperative music on the post-operative pain of abdominal surgery patients. Method A systematic review of Cochrane Library, PubMed, and Scopus identified randomised controlled trials comparing an intraoperative music intervention with standard care with postoperative pain as a measured outcome. To assess the quality of the studies and determine inclusion in meta-analysis the author collaborated with Robot Reviewer software based on the Cochrane bias methodology. Meta-analysis used standard mean difference and a random-effects model. Results The review found the majority of studies looking at intraoperative interventions determined that there was no significant impact on postoperative pain. However meta-analysis of the 250 subjects included determined that there is a significant reduction in pain (p = 0.02). The studies included also looked at opiod use, however this was not reported. Conclusions Whilst the meta-analysis is promising, findings support further investigation into intraoperative music as a low-cost addition to postoperative pain management.
