Background: Whether the presence of postoperative complications was associated with poor prognosis of gastric carcinoma (GC) patients remain controversial. This meta-analysis was designed and reported to compare the survival difference between patients with complications and non-complications. Methods: Cochrane Library, PubMed and Embase databases were comprehensively searched for published literatures to review current evidence on this topic. The survival data were extracted, and a random-effect or fixed-effect model was used to analyze the correlation between postoperative complications and oncologic outcome of GC patients. Results: Of all studies identified, 32 were eligible for this pooled analysis, with a total of 32,067 GC patients. The incidence of postoperative complications was approximately 12.5% to 51.0%. Among them, infectious complications varied from 3.0% to 28.6%, anastomotic leakage varied from 1.1% to 8.7% and postoperative pneumonia varied from 1.6% to 12.8%. The presence of postoperative complications resulted in a significant poorer overall survival (OS) of gastric carcinoma patients (hazard ratio [HR]:1.49, 95% confidence interval [CI]: 1.33-1.67, P < 0.001). Additionally, the pooled results showed a significant correlation between infectious complications and decreased OS (HR: 1.61, 95%CI: 1.38-1.88, P < 0.001). Concerning specific postoperative complications, we found that both anastomotic leakage (HR: 2.36, 95%CI: 1.62-3.42, P < 0.001) and postoperative pneumonia (HR: 1.74, 95%CI: 1.22-2.49, P = 0.002) impaired the OS of gastric carcinoma patients. Conclusion: Postoperative complications were significantly correlated to recurrence and poor survival in gastric carcinoma patients. To gain a better surgical outcome and long-term oncological outcome, postoperative complications should be minimized as much as possible.

Feeding Jejunostomy

Summary Feeding jejunostomy (FJ) is a routine procedure at the time of esophagectomy in some centers. With the widespread popularization of enhanced recovery after surgery, the necessity of FJ has been increasingly questioned. This study aims to analyze the differences in safety and effectiveness between with (FJ group) or without (no-FJ group) performing FJ at the time of esophagectomy. PubMed, Embase, Web of Science, and Cochrane Library were comprehensively searched for relevant studies, including randomized controlled trials and cohort studies. The primary outcome was the length of hospital stay (LOS). Secondary outcomes were overall postoperative complications, postoperative pneumonia, intestinal obstruction, and weight loss at 3 and 6 months after esophagectomy. Weighted mean differences (WMD) and odds ratios (OR) were calculated for statistical analysis. About 12 studies comprising 2,173 patients were included. The FJ group had a longer LOS (WMD = 2.05, P = 0.01) and a higher incidence of intestinal obstruction (OR = 11.67, P &lt; 0.001) than the no-FJ group. The incidence of overall postoperative complications (OR = 1.24, P = 0.31) and postoperative pneumonia (OR = 1.43, P = 0.13) were not significantly different, nor the weight loss at 3 months (WMD = 0.58, P = 0.24) and 6 months (P &gt; 0.05) after esophagectomy. Current evidence suggests that routinely performing FJ at the time of esophagectomy appears not to generate better postoperative outcomes. FJ may need to be performed selectively rather than routinely. More studies are required to further verify.

Background. Perioperative and follow-up outcomes for patients that received robot-assisted kidney transplant (RAKT), compared to patients that received conventional open kidney transplant (OKT), remain unknown. We performed a meta-analysis of controlled studies to compare the safety and efficacy of RAKT versus OKT. Methods. Systematic searching of PubMed, Embase, and Cochrane Library databases was performed to identify relevant randomized or nonrandomized controlled studies. Perioperative, in-hospital, and follow-up outcomes were summarized. A random-effect model incorporating the potential heterogeneity was used to synthesize the results. Results. Six nonrandomized controlled studies including 263 patients with RAKT and 804 patients with OKT were included. Pooled results showed that compared to those that received OKT, patients that received RAKT had significant higher rewarming time (mean difference (MD): 20.8 min, p < 0.001 ) and total ischemia time (MD: 17.8 min, p = 0.008 ) but a lower incidence of surgical site infection (SSI, risk ratio (RR): 0.22, p = 0.03 ). The incidence of delayed graft function was comparable between groups (RR: 1.10, p = 0.82 ), and the length of hospital stay was similar (MD: -2.03 days, p = 0.21 ). During a follow-up of 31 months, patients that received RAKT and OKT had similar serum creatinine levels (MD: 10.12 mmol/L, p = 0.42 ) and similar incidences of graft rejection (RR: 1.16, p = 0.53 ), graft failure (RR: 0.94, p = 0.79 ), and all-cause mortality (RR: 1.16, p = 0.77 ). Conclusion. Current evidence from nonrandomized studies suggests that RAKT is associated with a lower risk of SSI and similar midterm functional and clinical efficacy compared to OKT. Randomized studies are needed to validate these findings.

Abstract Background Osteosarcoma is a relatively rare malignant tumor with a high incidence in young people. The development of tyrosine kinase inhibitors has brought the treatment of osteosarcoma into a new stage. Apatinib, a tyrosine kinase inhibitor specifically targeting VEGFR2, has been increasingly reported as a treatment for osteosarcoma with promising outcome parameters, but there has been no systematic analysis of the treatment of osteosarcoma by apatinib. Methods A single-arm meta-analysis was performed, and published literature from PubMed, Web of Science, Embase, Cochrane Library, CNKI and Wan Fang databases as of March 1, 2021 was systematically retrieved. Quality assessment is carried out in accordance with a 20 item checklist form prepared by the Institute of Health Economics (IHE). Double arcsine transformation is performed to stabilize the variance of the original ratio. When I2 > 50%, the random effect model is used to calculate the pooled parameters; otherwise, the fixed effect model is used. We conducted subgroup analysis according to age and apatinib dose. Results This meta-analysis included 11 studies of 356 Chinese patients with osteosarcoma. The pooled objective remission rate (ORR) of advanced or metastatic osteosarcoma treated by oral apatinib in Chinese patients was 0.27(95%CI = 0.18–0.38). The pooled disease control rate (DCR) was 0.57 (95%CI = 0.42–0.72). The pooled median progression-free survival (mPFS) and median total survival (mOS) were 5.18 months (95%CI = 4.03–6.33) and 10.87 months (95% CI = 9.40–12.33), respectively. More than 70% of adverse reactions were mild, the most common adverse reaction was hand-foot syndrome (HFMD), with an incidence of 0.46 (95%CI = 0.35–0.58), the second was hypertension, with an incidence of 0.40 (95%CI = 0.29–0.51). Conclusions The efficacy of apatinib in the treatment of osteosarcoma is competitive with current evidence, and it is worth noting that its low cost can significantly improve patient compliance and increase therapeutic value.

The Impact

BackgroundGarlic is a species in the onion genus, Allium. Data have shown that garlic has anti-inflammatory activity; however, the findings are inconclusive and inconsistent. We aimed to evaluate the impact of garlic intake on inflammatory mediators through systematic review and meta-analysis of existing data.MethodsElectronic databases were completely investigated using databases of ISI Web of Science, Medline, Scopus, Cochrane Library and EMBASE until October 2019. A random effects model and the generic reverse variance procedure were used for quantitative data production. Sensitivity analyses and prespecified subgroup were done to evaluate potential heterogeneity. Random effect meta-regression was conducted to investigate the effects of possible confounders on the assessed effect size.ResultsTen trials with one observational study, including 530 participants, met the eligibility criteria. The findings showed reduction in the tumour necrosis factor alpha (TNF-α) (−0.31 pg/mL, 95% CI −1.07 to 0.46) and C reactive protein (CRP) levels (−0.20 mg/L, 95% CI −1.4 to 1.05) following supplementation with garlic, although it had no marked impact on the interleukin 6 (IL-6) level (0.37 pg/mL, 95% CI −0.58 to 1.33). In the subgroup analysis, we found that garlic supplementation significantly decreased TNF-α, highly sensitive CRP and IL-6 levels in subgroups of >8, >6 and ≥4 weeks of intervention duration, respectively, and dose of garlic consumption between 2 and 2.4 g/day.ConclusionThese findings suggested that current evidence may support garlic as an adjunct to pharmacological management of metabolic diseases.PROSPERO registration numberCRD42018108816.

Background: Although microscopic (MTSS) and endoscopic transsphenoidal surgery (ETSS) are both effective approaches for treating non-functioning pituitary adenomas (NFPA) and functioning pituitary adenomas (FPA), the consensus remains unidentified on whether there are differences in the risk of postoperative complications between the two surgical approaches.Method: A meta-analysis of the study of MTSS vs. ETSS for NFPA and FPA was conducted by searching the electronic databases of PubMed, Cochrane Library, and EMBASE, from the date of establishment of electronic databases to September 2020 based on the PRISMA guidelines.Results: In this study, a total of 16 studies were selected, hailing from Belgium, the USA, India, Finland, France, Korea, Spain, China, and Canada. We enrolled 1003 patients in the ETSS and 992 patients in the MTSS group. In patients with NFPA, the ETSS group was related to a higher incidence of post-operative gross-total resection (GTR). (OR = 1.655, 95% CI 1.131–2.421, P = 0.010). In participants with FPA, the results illustrated that the ETSS group had higher rates of visual improvement (OR = 2.461, 95% CI 1.109–5.459) and gross-total resection (OR = 2.033, 95% CI 1.335–3.096), as well as lower meningitis rates (OR = 0.195, 95% CI 0.041–1.923). In participants with acromegaly, no significant difference was shown in the postoperative complications.Conclusion: Based on current evidence, participants with NFPA treated by endoscopy were related to higher rates of GTR; patients with FPA treated by ETSS were related to higher rates of visual improvement and GTR, as well as a lower rates of meningitis.

AbstractThis study compared weight and cardiometabolic changes after short-term treatment of olanzapine/samidorphan and olanzapine. Eligible criteria for an included trial were ≤ 24 weeks, randomized controlled trials (RCTs) that compared olanzapine/samidorphan and olanzapine treatments in patients/healthy volunteers and reported weight or cardiometabolic outcomes. Three databases were searched on October 31, 2020. Primary outcomes included weight changes and all-cause dropout rates. Standardized mean differences (SMDs) and risk ratios (RRs) were computed and pooled using a random-effect model. This meta-analysis included four RCTs (n = 1195). The heterogeneous data revealed that weight changes were not significantly different between olanzapine/samidorphan and olanzapine groups (4 RCTs, SDM = − 0.19, 95% CI − 0.45 to 0.07, I2 = 75%). The whole-sample, pooled RR of all-cause dropout rates (4 RCTs, RR = 1.02, 95% CI 0.84 to 1.23, I2 = 0%) was not significant different between olanzapine/samidorphan and olanzapine groups. A lower percentage of males and a lower initial body mass index were associated with the greater effect of samidorphan in preventing olanzapine-induced weight gain. Current evidence is insufficient to support the use of samidorphan to prevent olanzapine-induced weight gain and olanzapine-induced cardiometabolic abnormalities. Samidorphan is well accepted by olanzapine-treated patients.

Abstract Introduction and hypothesis Sacrocolpopexy and sacrospinous ligament fixation (SSLF) have been used for the restoration of apical support. Studies comparing sacrocolpopexy and SSLF have reported conflicting results. We aim to assess the current evidence regarding efficiency and the complications of sacrocolpopexy compared with SSLF. Methods We searched PubMed, Embase, and Cochrane Library and performed a systematic review meta-analysis to assess the two surgical approaches. Results 5Five randomized controlled trials, 8 retrospective studies, and 2 prospective studies including 4,120 cases were identified. Compared with abdominal sacrocolpopexy (ASC), SSLF was associated with a lower success rate (88.32% and 91.45%; OR 0.52; 95% CI 0.29–0.95; p = 0.03), higher recurrence (11.58% and 8.32%; OR 1.97; 95% CI 1.04–3.46; p = 0.04), and dyspareunia rate (14.36% and 4.67%; OR 3.10; 95% CI 1.28–7.50; p = 0.01). Patients in this group may benefit from shorter operative time (weighted mean difference −25.08 min; 95% CI −42.29 to −7.88; p = 0.004), lower hemorrhage rate (0.85% and 2.58%; OR 0.45; 95% CI 0.25–0.85; p = 0.009), wound infection rate (3.30% and 5.76%; OR 0.55; 95% CI 0.39–0.77; p = 0.0005), and fewer gastrointestinal complications (1.33% and 6.19%; OR 0.33; 95% CI 0.15–0.76; p = 0.009). Conclusion Both sacrocolpopexy and SSLF offer an efficient alternative to the restoration of apical support. When anatomical durability and sexual function is a priority, ASC may be the preferred option. When considering factors of mesh erosion, operative time, gastrointestinal complications, hemorrhage, and wound infections, SSLF may be the better option.

Objective. The purpose of this study was to assess the effectiveness and safety of acupuncture for functional constipation (FC). Methods. A rigorous literature search was performed in English (PubMed, Web of Science, the Cochrane Library, and EMBASE) and Chinese (China National Knowledge Infrastructure (CNKI), Chinese Biological Medical (CBM), Wanfang database, and China Science and Technology Journal (VIP)) electronic databases from their inception to October 2019. Included randomized controlled trials (RCTs) compared acupuncture therapy with sham acupuncture or pharmacological therapies. The outcome measures were evaluated, including the primary outcome of complete spontaneous bowel movement (CSBM) and secondary outcomes of Bristol Stool Form Scale (BSFS), constipation symptoms scores (CSS), responder rate, the Patient Assessment of Constipation Quality of Life (PAC-QOL) questionnaire, and safety evaluation. Meta-analysis was performed by using RevMan5.3. Results. The merged data of 28 RCTs with 3525 participants indicated that acupuncture may be efficient for FC by increasing CSBMs (p<0.00001; MD = 0.84 [95% CI, 0.65 to 1.03]; I2 = 0%) and improving constipation symptoms (p=0.03; SMD = −0.4 [95% CI, −0.78 to −0.03]; I2 = 74%), stool formation (p<0.00001; MD = 0.24 [95% CI, 0.15 to 0.34]; I2 = 0%), quality of life (p<0.00001; N = 1, MD = −0.33 [95% CI, −0.45 to −0.21]), and responder rates (p=0.02; RR = 2.16; [95% CI, 1.1 to 4.24]; I2 = 69%) compared with the effects of sham treatment. No increased risk of adverse events was observed (p=0.44; RR = 1.18; [95% CI, 0.77 to 1.81]; I2 = 0%). With regard to medication comparisons, the pooled data indicated that acupuncture was more effective in increasing CSBMs (p=0.004; MD = 0.53 [95% CI, 0.17 to 0.88]; I2 = 88%) and improving patients’ quality of life (p<0.00001; SMD = −0.73 [95% CI, −1.02 to −0.44]; I2 = 64%), with high heterogeneity. However, there were no significant differences in responder rate (p=0.12; RR = 1.31; [95% CI, 0.94 to 1.82]; I2 = 53%), BSFS (p=0.5; MD = 0.17 [95% CI, −0.33 to 0.68]; I2 = 93%), or CSS (p=0.05; SMD = −0.62 [95% CI, −1.23 to −0.01]; I2 = 89%). Regarding safety evaluation, acupuncture was safer than medications (p<0.0001; RR = 0.3; [95% CI, 0.18 to 0.52]; I2 = 30%). Conclusions. Current evidence suggests that acupuncture is an efficient and safe treatment for FC. Acupuncture increased stool frequency, improved stool formation, alleviated constipation symptoms, and improved quality of life. However, the evidence quality was relatively low and the relationship between acupuncture and drugs is not clear. More high-quality trials are recommended in the future.

Abstract Funding Acknowledgements Type of funding sources: None. Background The ‘Atrial Fibrillation Better Care’ (ABC) pathway has been recently proposed as a holistic approach for the comprehensive management of patients with Atrial Fibrillation (AF), standing on three main pillars: ‘A’ Avoid stroke (with Anticoagulants); ‘B’ Better symptom management; ‘C’ Cardiovascular and Comorbidity management. The ABC pathway is now recommended in several clinical guidelines, including the recent European Society of Cardiology (ESC) AF management guidelines. We performed a systematic review of the current evidence for use of the ABC pathway on clinical outcomes. Methods We performed a systematic review and meta-analysis according to PRISMA Guidelines. Pubmed and EMBASE were searched for studies reporting the prevalence of ABC pathway adherent management in AF patients, and its impact on clinical outcomes (all-cause death, cardiovascular death, stroke, and major bleeding). Metanalysis of odds ratio (OR) was performed with random-effect models; subgroup analysis and meta-regression were performed to account for heterogeneity; a CHA2DS2-VASc-stratified sensitivity analysis was also performed. Results Among 2862 records retrieved from the literature search, 8 studies were included. The pooled prevalence of ABC adherent management was 21% (95% confidence intervals (CI), 13-34%), with a high grade of heterogeneity; in a multivariable meta-regression model, adherence to each criteria of the ABC pathway explained most part of the heterogeneity (R2 = 98.9%). Patients treated according to the ABC pathway showed a lower risk of all-cause death (OR:0.42, 95%CI 0.31-0.56), cardiovascular death (OR:0.37, 95%CI 0.23-0.58), stroke (OR:0.55, 95%CI 0.37-0.82) and major bleeding (OR:0.69, 95%CI 0.51-0.94), with moderate heterogeneity. Meta-regressions showed that the increasing prevalence of diabetes mellitus, coronary artery disease, chronic heart failure and history of stroke were associated with a reduced effectiveness of the ABC pathway for all-cause and cardiovascular death; each comorbidity was able to explain a significant proportion of heterogeneity at univariate meta-regression. Conversely, longer follow-up time was associated with more effectiveness of the ABC pathway for all outcomes. Adherence to ABC pathway was associated with a progressively greater reduction of the all-cause death risk amongst patients with higher CHA2DS2-VASc scores; no difference in ABC pathway effectiveness was found across CHA2DS2-VASc strata for CV death and stroke occurrence. Conclusions Adherence to the ABC pathway was suboptimal, being adopted in 1 in every 5 patients. Adherence to the ABC pathway was associated with a reduction in the risk of major adverse outcomes. Our data supports extensive application of the ABC pathway for the management of AF. Abstract Figure.

Abstract Funding Acknowledgements Type of funding sources: None. Background novel oral anticoagulants (NOACs) are not guideline-recommanded treatment for left ventricular thrombus.  Purpose: the aim of this meta-analysis is to compare NOACs versus vitamin-K atagonsits (VKAs) efficacy in treating left ventricular thrombus (LVT). Methods: we systematically searched MEDLINE, Cochrane Library, Biomed Central, and Web of Science for trials comparing NOACs versus VKAs in the setting of LVT. Five studies, out of the 74 initially selected after first screening, were included in the meta-analysis. For the development of this meta-analysis, the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines were followed. The shortlisted studies were retrieved as full articles and appraised independently by two unblinded reviewers. The Mantel-Haensel method with a random effect model was used for the pooled analysis. The primary outcome was the occurrence of stroke and systemic embolism. Secondary outcome was occurrence of left ventricular thrombosis resolution during treatment.  Results: 707 patients were included in the analysis for the primary outcome. Of these, 230 were treated with NOACs and 477 with VKAs. The pooled OR for the primary outcome was 0.71 (95% CI 0.18-2.86, I2 67%), thus showing similar effect in term of ischaemic protection. A total of 698 patients, 228 on NOACs and 470 on VKAs were included in the analysis of the secondary outcome. The pooled OR for the secondary outcome pooled OR 0.97, 95% CI 0.56-1.68, I2 46%. Conclusions and Relevance: NOACs seem to have a similar efficacy profile compare to VKAs and so they should be considered as an alternative treatment for left ventricular thrombosis. Large prospective randomized clinical trials are needed to confirm this exploratory finding. Abstract Figure 1
