The objective of this study was to evaluate the impact of perioperative glutamine-supplemented parenteral nutrition (GLN-PN) on clinical outcomes in patients undergoing abdominal surgery. MEDLINE, EMBASE, and the Cochrane Controlled Clinical Trials Register were searched to retrieve the eligible studies. Eligible studies were randomized controlled trials (RCTs) that compared the effect of GLN-PN and standard PN on clinical outcomes in patients undergoing abdominal surgery. Clinical outcomes of interest were postoperative mortality, length of hospital stay, morbidity of infectious complication, and cumulative nitrogen balance. Statistical analysis was conducted by RevMan 5.0 software from the Cochrane Collaboration. Sixteen RCTs with 773 patients were included in this meta-analysis. The results showed a significant decrease in the infectious complication rates of patients undergoing abdominal surgery receiving GLN-PN (risk ratio [RR], 0.48; 95% confidence interval [CI], 0.32 to 0.72; P = 0.0004). The overall effect indicated glutamine significantly reduced the length of hospital stay in the form of alanyl-glutamine (weighted mean difference [WMD], -3.17; 95% CI, -5.51 to -0.82; P = 0.008) and in the form of glycyl-glutamine (WMD, -3.40; 95% CI, -5.82 to -0.97; P = 0.006). A positive effect in improving postoperative cumulative nitrogen balance was observed between groups (WMD, 7.40; 95% CI, 3.16 to 11.63; P = 0.0006), but no mortality (RR, 1.52; 95% CI, 0.21 to 11.9; P = 0.68). Perioperative GLN-PN is effective and safe to shorten the length of hospital stay, reduce the morbidity of postoperative infectious complications, and improve nitrogen balance in patients undergoing abdominal surgery.

181 Background: Several reports have linked noncompliance with radiotherapy (RT) protocol guidelines with inferior clinical outcomes. Here we perform a meta-analysis of prospective cooperative group trials to determine the impact of RT quality assurance (QA) deviations on disease control and overall survival (OS). Methods: We searched MEDLINE and the Cochrane Central Register of Controlled Trials for multi-institutional trials that reported clinical outcomes in relation to RT quality assurance (QA) results. Hazard ratios (HRs) describing the impact of RT protocol noncompliance on outcomes were extracted directly from the original studies or calculated from survival curves. Analyses were performed to assess the impact of RT QA deviations on OS and secondary outcomes (local/locoregional control, event-free survival, relapse), which were grouped together. Pooled estimates were obtained using the inverse variance method. A random effects model was used in cases of significant effect heterogeneity (p<0.10 using Q test). Results: Eight studies met all inclusion criteria and were incorporated into this analysis. Four were pediatric trials (POG 8346, SFOP.TC 94, POG 9031, SIOP/UKCC PNET-3), and four studied adult patients (RTOG 73-01, SWOG 7628, TROG 02.02, RTOG 97-04). Six of these trials reported the impact of RT QA deviations on overall survival, and six described the effects of RT QA deviations on secondary endpoints. The frequency of RT QA deviations ranged from 8% to 71% (median: 40%). Using a random effects model, RT deviations were associated with a significant decrease in OS (HR = 1.74, 95% CI: 1.28 to 2.35, p<0.001). A similar effect was seen for secondary endpoints (HR = 1.79, 95% CI: 1.15 to 2.78, p=0.009). No evidence of publication bias was detected using the Egger test (p=0.361 for OS, p=0.468 for secondary endpoints). Conclusions: In clinical trials, RT protocol deviations are associated with increased risk of treatment failure and overall mortality. The magnitude of these effects demonstrates that RT QA results should be considered in the interpretation of clinical trial results. More importantly, the delivery of high-quality RT is critical for the successful treatment of cancer patients.

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.

<b><i>Background:</i></b> Patients with chronic obstructive pulmonary disease (COPD) are at a heightened risk of pneumonia. Whether coexisting community-acquired pneumonia (CAP) can predict increased mortality in hospitalized COPD patients is still controversial. <b><i>Objective:</i></b> This systematic review and meta-analysis aims to assess the association between CAP and mortality and morbidity in COPD patients hospitalized for acute worsening of respiratory symptoms. <b><i>Methods:</i></b> In this review, cohort studies and case-control studies investigating the impact of CAP in hospitalized COPD patients were retrieved from 4 electronic databases from inception until December 2019. Methodological quality of included studies was assessed using Newcastle-Ottawa Quality Assessment Scale. The primary outcome was mortality. The secondary outcomes included length of hospital stay, need for mechanical ventilation, intensive care unit (ICU) admission, length of ICU stay, and readmission rate. The Mantel-Haenszel method and inverse variance method were used to calculate pooled relative risk (RR) and mean difference (MD), respectively. <b><i>Results:</i></b> A total of 18 studies were included. The presence of CAP was associated with higher mortality (RR = 1.85; 95% CI: 1.50–2.30; <i>p</i> &#x3c; 0.00001), longer length of hospital stay (MD = 1.89; 95% CI: 1.19–2.59; <i>p</i> &#x3c; 0.00001), more need for mechanical ventilation (RR = 1.48; 95% CI: 1.32–1.67; <i>p</i> &#x3c; 0.00001), and more ICU admissions (RR = 1.58; 95% CI: 1.24–2.03; <i>p</i> = 0.0002) in hospitalized COPD patients. CAP was not associated with longer ICU stay (MD = 5.2; 95% CI: −2.35 to 12.74; <i>p</i> = 0.18) or higher readmission rate (RR = 1.02; 95% CI: 0.96–1.09; <i>p</i> = 0.47). <b><i>Conclusion:</i></b> Coexisting CAP may be associated with increased mortality and morbidity in hospitalized COPD patients, so radiological confirmation of CAP should be required and more attention should be paid to these patients.

Abstract Background The outcomes of post-stroke delirium are inconsistent. Therefore, we conduct a meta-analysis to provide a comprehensive description of the impact of delirium on the outcomes including including length of hospital stay and inpatient mortality after stroke. Methods We searched electronic databases including PubMed, Google scholar, Web of Science and Cochrane Library databases up to April, 2021. Fixed-effect or random-effect model was used to summary odds ratio (OR) and mean difference (MD ) with 95% confidence interval (CI). Results 13 individual studies with total of 3592 patients met the inclusion criteria. The summary results revealed that stroke patients with delirium increased risk of inpatient mortality (OR = 6.35, 95% CI: 4.35–9.25, p < 0.0001), and had longer length of hospital stay (MD = 5.93, 95% CI: 2.79–9.07, p < 0.0001) compared to non-delirious patients. Conclusions Delirium is associated with unfavorable outcomes in patients with stroke, particularly in higher inpatient mortality and longer length of stay. We should pay more attention to this clinical problem and managed appropriately to prevent poor prognosis.

Objective: Comparing the clinical outcomes of laparoscopic and abdominal sacrocolpopexy in vaginal vault prolapse post-hysterectomy’s patient. Method: Systematic search data is performed on medical database (PUBMED, Cochrane Database) using keyword:(1) vault prolapse [title] AND (2) laparoscopic[title] AND sacrocolpopexy[title]. Inclusion criteria:(1) randomized controlled trial and observational studies, (2) women with vaginal vault prolapse post hysterectomy, (3) intervention studied: laparoscopic (LSC) and abdominal sacrocolpopexy (ASC), (4) the entire fully accessible papers can be accessed and data can be accurately analyzed. Comparison about clinical outcomes of LSC and ASC was performed using narrative analysis and meta-analysis (RevMan). Results: Three studies compared clinical outcomes of LSC and ASC with a total of 243 samples (118 in LSC and 125 in ASC group). There was no significant difference in the incidence of complications between LSC and ASC (OR 1.10;95%CI 0.58-2.08). LSC was associated with less blood loss (MD 111.64 mL,95%CI-166.13 - -57.15 mL) and shorter length of hospital stay (MD -1.82 days;95%CI -2.52- -1.12 days) but requires a longer operating time (MD 22.82 minutes,95%CI 0.43-45.22 minutes). There was no statistically significant difference to anatomical outcomes (measurement of point C on POP-Q), subjective outcomes measured by PGI-I and reoperation numbers (repeat surgical interventions) for prolapse recurrence between LSC and ASC groups after one year of follow-up. Conclusions: LSC showed similar anatomic results compared to ASC with less blood loss and shorter length of hospital stay in management patient with vaginal vault prolapse.

Abstract Background Tacrolimus (Tac) is the cornerstone of immunosuppressant therapy after lung transplantation (LTx). It shows great inter-individual variability in pharmacokinetics, which could partly be explained by pharmacogenetic factors. Objective We aim to investigate the effect of cytochrome P450 3A5 (CYP3A5) (rs776746) genotypes on early post-operative Tac metabolism and clinical outcomes in LTx recipients. Methods 90 recipients who underwent LTx from 2017 to 2019 at our institution were enrolled in the study. The effect of CYP3A5 genotype on Tac concentration, dose, dose adjusted concentration (C/D) and interaction with azole antifungals were assessed during week 1–4 after transplantation. Associations between CYP3A5 genotype and the incidence of acute kidney injury (AKI), length of hospital stay and mortality were analyzed. Results CYP3A5*1 carriers had lower C/D than CYP3A5*3/*3 group at all time points (p < 0.05). To reach comparable blood concentrations, CYP3A5*1 carriers required higher doses compared with CYP3A5*3/*3 group (p < 0.05). Use of azole antifungals did not blunt the effect of CYP3A5 genotypes on Tac metabolism. Logistic regression showed Tac concentration at week 1, not CYP3A5 genotype, was associated with the incidence of AKI. No statistically significant difference was found between CYP3A5 genotypes and the length of hospital stay (48 (37–68) vs 46(32–57) days, p = 0.264). Kaplan–Meier analysis showed no statistically significant difference between 30-day or 1-year mortality and CYP3A5 genotype. Conclusion CYP3A5 genotype could affect Tac metabolism early after LTx. However, it has no influence on the incidence of AKI, length of hospital stay and mortality.

<b><i>Background:</i></b> The effect of immunonutrition in patients undergoing hepatectomy remains unclear. This meta-analysis aimed to assess the impact of immunonutrition on postoperative clinical outcomes in patients undergoing hepatectomy. <b><i>Methods:</i></b> A literature search of PubMed, Cochrane Library, Web of Science, and Embase databases was performed to identify all randomized controlled trials (RCTs) exploring the effect of perioperative immunonutrition in patients undergoing hepatectomy until the end of March 10, 2020. Quality assessment and data extraction of RCTs were conducted independently by 3 reviewers. Mean difference (MD) and odds ratio (OR) with 95% confidence interval (CI) were calculated using a fixed-effects or random-effects model. The meta-analysis was performed with RevMan 5.3 software. <b><i>Results:</i></b> Nine RCTs involving a total of 966 patients were finally included. This meta-analysis showed that immunonutrition significantly reduced the incidences of overall postoperative complications (OR = 0.57, 95% CI: 0.34–0.95; <i>p</i> = 0.03), overall postoperative infectious complications (OR = 0.53, 95% CI: 0.37–0.75; <i>p</i> = 0.0003), and incision infection (OR = 0.50, 95% CI: 0.28–0.89; <i>p</i> = 0.02), and it shortened the length of hospital stay (MD = −3.80, 95% CI: −6.59 to −1.02; <i>p</i> = 0.007). There were no significant differences in the incidences of pulmonary infection (OR = 0.60, 95% CI: 0.32–1.12; <i>p</i> = 0.11), urinary tract infection (OR = 1.30, 95% CI: 0.55–3.08; <i>p</i> = 0.55), liver failure (OR = 0.54, 95% CI: 0.23–1.24; <i>p</i> = 0.15), and postoperative mortality (OR = 0.69, 95% CI: 0.26–1.83; <i>p</i> = 0.46). <b><i>Conclusion:</i></b> Given its positive impact on postoperative complications and the tendency to shorten the length of hospital stay, perioperative immunonutrition should be encouraged in patients undergoing hepatectomy.

Background: The effect of enteral immunonutrition (EIN) in patients undergoing pancreaticoduodenectomy (PD) is still doubtful. This meta-analysis aimed to assess the impact of EIN on postoperative clinical outcomes for patients undergoing PD. Methods: A literature search was carried out to identify all of the randomized controlled trials (RCTs) concerning the use of EIN for PD. Data collection ended on April 1, 2018. Pooled risk ratios (RRs) and the mean difference (MD) with a 95% CI were calculated using fixed effects or random effects models. The analyses were performed with RevMan 5.3.5. Results: Four RCTs with a total of 299 patients were included. Immunonutrition reduced the incidence of postoperative infectious complications (RR 0.58, 95% CI 0.37–0.92; p = 0.02) and shortened the length of hospital stay (MD –1.79, 95% CI –3.40 to 0.18; p = 0.03). Conversely, there were no significant differences in the incidence of overall postoperative complications (RR 0.81, 95% CI 0.62–1.05; p = 0.11), non-infectious complications (RR 0.94, 95% CI 0.69–1.28; p = 0.70) and postoperative mortality (RR 2.43, 95% CI 0.37–16.10; p = 0.36). Conclusions: EIN reduced postoperative infectious complications and shortened the length of the hospital stay; immunonutrition should be encouraged in patients undergoing PD.

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.
