<b><i>Introduction:</i></b> Surgery is commonly regarded as the mainstay of treatment of extramammary Paget disease (EMPD)<b><i>;</i></b> however, nonsurgical approaches have gained popularity in recent years. <b><i>Objectives:</i></b> To review the published evidence for the efficacy and safety of nonsurgical modes of therapy for EMPD. <b><i>Methods:</i></b> A systematic review and meta-analysis of nonsurgical EMPD treatments was performed. The primary outcome was complete response (CR); secondary outcomes were clinical regression by ≥50%, adverse events, and recurrence rate. <b><i>Results:</i></b> The systematic review included 43 observational studies (341 patients; 7 prospective cohort studies, 19 retrospective cohort studies, and 17 cases series) evaluating 5 treatment modalities. Imiquimod (13 studies, 110 patients) administered at variable doses ranging from daily to twice weekly for 2–56 weeks demonstrated CR of 54% (95% CI, 40–67%; <i>I</i><sup>2</sup> = 37%) and had a satisfactory safety profile. In 14 heterogeneous studies (122 patients) evaluating photodynamic therapy (PDT), only 36% (95% CI, 22–53%; <i>I</i><sup>2</sup> = 52%) of patients achieved CR. Radiotherapy (12 studies, 67 patients) showed CR of 97%, but was associated with local and systemic side effects. Ablative lasers and topical fluorouracil and calcipotriene lacked adequate evidence of efficacy. <b><i>Conclusions:</i></b> Imiquimod and radiotherapy are the most appropriate nonsurgical modalities for EMPD treatment given their good efficacy and safety profile. PDT has limited efficacy but may be appropriate in selected clinical settings.

Objective To investigate the relationship between maternal exposure to alcohol and low birthweight (LBW). Methods The literature search was performed in January 2017 using the following electronic databases: Medline, Embase, LILACS, SciELO, Web of Science, Scopus, CINHAL, Proquest, and PsychInfo. The search strategy used the following terms: alcohol drinking, binge drinking, alcohol-related disorders, alcoholism, alcohol addiction/use/abuse/consumption, light/moderate/social/low drinking, low birthweight, case-control studies, retrospective studies, and cohort studies. No restrictions regarding language or publication date were considered. The literature search yielded 2,383 articles, and after screening and eligibility assessment, 39 articles were included in the systematic review, and 38 studies were included in the meta-analysis. Results Maternal alcohol consumption was associated with LBW among retrospective cohort studies (relative risk [RR] = 1.37; 95%CI [confidence interval]:1.10–1.77; I2 = 98.4%; p < 0.01). Prospective cohort studies (RR = 1.11; 95%CI: 0.98–1.25; I2 = 81.5%; p < 0.01), and case-control studies (odds ration [OR] = 1.16; 95%CI: 0.68–1.97; I2 = 61.2%; p = 0.05) showed no association between alcohol and LBW. No publication bias was identified, and the meta-regression showed that the sample size influenced the high heterogeneity among retrospective cohort studies. The subgroup analysis showed differences in association between groups when compared by sample size, type of adjustment, or crude measures and publication year. Conclusions We have not found an association between alcohol consumption during gestation and LBW in the analysis in all of the subgroups. In addition, we have found a high heterogeneity between the primary studies, which is related to methodological differences in the conduction of these studies.

e14113 Background: Immune checkpoint inhibitors (ICIs) that target programmed cell death 1 (PD-1) and its ligand (PD-L1) have led to a paradigm shift in cancer treatment, while whether PD-1 and PD-L1 inhibitors deliver different clinical outcomes remains obscure. Here we carried out a systematic review and meta-analysis to compare the efficacy and safety profile of PD-1 and PD-L1 inhibitors in pan-cancer patients. Methods: We systematically searched PubMed, Cochrane library, and Embase from January 2000 to December 2018 for randomized controlled trials that compared PD-1/PD-L1 inhibitors with standard treatment in patients with solid tumors. We also reviewed abstracts and presentations from all major conference proceedings. Retrospective studies and trials that compared anti-PD-1/PD-L1 with other immunotherapies were excluded. The primary outcome was the difference in overall survival (OS). Studies were stratified into comparison groups upon studies mirrored with trial design and patient characteristics. Effect size in each comparison group was pooled first, the difference in overall survival was estimated, and the overall effect sizes was pooled using a random-effects model. Results: A total of 3864 publications were retrieved through initial literature search, 17 randomized controlled trials involving 9549 patients with solid tumors were included for this meta-analysis. PD-1 inhibitors exhibited significantly improved OS over PD-L1 inhibitors either in overall population (HR 0.75, 95% CI 0.64-0.87), as monotherapy (HR 0.79, 95% CI 0.65-0.96), or combination with chemotherapy (HR 0.66, 95% CI 0.53-0.82). PD-1 inhibitors also showed improved progression free survival (PFS) over PD-L1 inhibitors in overall population (HR 0.70, 95% CI 0.53-0.94). No significant difference was observed for safety profile between PD-1 inhibitors and PD-L1 inhibitors as monotherapy. PD-1 inhibitors plus chemotherapy have less Grade 3-5 adverse events than PD-L1 inhibitors plus chemotherapy (overall RR 0.84, 95% CI 0.75-0.93). Sensitivity analysis presented a satisfactory consistency of the overall estimates across these analyses. Conclusions: PD-1 inhibitors exhibited better clinical performance for survival outcome and safety profile over PD-L1 inhibitors. Future studies and explorations of the underlying mechanisms are needed for the further optimization of treatment strategies in clinical practice.

The Relationship

ObjectivesTo analyse the relationship between serum uric acid (SUA), all-cause and cardiovascular (CV) mortality in peritoneal dialysis (PD) patients to inform clinical practice and future research.DesignA systematic review of observational studies.Data sourcesPubMed, Embase, Web of Science, the Cochrane Library, China National Knowledge Infrastructure (CNKI), SinoMed, Chinese Science and Technology Journal Database (VIP) and Wan Fang databases were searched from their inception to January 2021 for cohort and case–control studies reporting SUA and mortality in patients with PD.MethodsThe Newcastle-Ottawa Quality Assessment Scale was used to appraise quality of cohort and case–control studies. Effect estimates were presented as HRs with 95% CIs in a meta-analysis using STATA V.16.0. Data not suitable for pooling were synthesised qualitatively.ResultsFourteen cohort studies with 24 022 patients were included. No case–control studies were identified. For prospective cohort studies, pooled results for the highest SUA category were significantly greater than the lowest for all-cause (one study; 1278participants; HR 1.79; 95% CI 1.17 to 2.75) and CV mortality (one study; 1278 participants; HR 2.63; 1.62–4.27). An increase of 1 mg/dL in SUA level was associated with a 16% increased risk of all-cause mortality (one study; 1278 participants; HR 1.16; 1.03–1.32) and 34% increased CV mortality risk (one study; 1278 participants; HR 1.34; 1.16–1.55). For retrospective cohort studies, the highest SUA category did not demonstrate an elevated all-cause (five studies; 4570 participants; HR 1.09; 0.70–1.70) or CV mortality (three studies; 3748 participants; HR 1.00; 0.44–2.31) compared with the lowest SUA category. Additionally, there was no increase in all-cause (eight studies; 11 541 participants; HR 0.94; 0.88–1.02) or CV mortality (three studies; 7427 participants; HR 0.90; 0.76–1.06) for every 1 mg/dL increase in SUA level.ConclusionsResults of prospective and retrospective cohort studies were inconsistent. Consequently, prospective, multicentre, long-term follow-up studies are required to confirm the relationship between SUA and mortality in patients with PD.

ObjectivesTo conduct a systematic review and meta-analysis of the efficacy and safety of abdominal paracentesis drainage (APD) in patients with acute pancreatitis (AP) when compared with conventional ‘step-up’ strategy based on percutaneous catheter drainage (PCD).DesignSystematic review and meta-analysis.MethodsPubMed, EMBASE, Cochrane Library, MEDLINE (OVID), China National Knowledge Infrastructure and Wanfang Database were electronically searched to collect cohort studies and randomised controlled trials (RCTs) from inception to 25 July 2020. Studies related to comparing APD with conventional ‘step-up’ strategy based on PCD were included.OutcomesThe primary outcome was all-cause mortality. The secondary outcomes were the rate of organ dysfunction, infectious complications, hospitalisation expenses and length of hospital stay.ResultsFive cohort studies and three RCTs were included in the analysis. Compared with the conventional ‘step-up’ method, pooled results suggested APD significantly decreased all-cause mortality during hospitalisation (cohort studies: OR 0.48, 95% CI 0.26 to 0.89 and p=0.02), length of hospital stay (cohort studies: standard mean difference (SMD) −0.31, 95% CI −0.53 to –0.10 and p=0.005; RCTs: SMD −0.45, 95% CI −0.64 to –0.26 and p<0.001) and hospitalisation expenses (cohort studies: SMD −2.49, 95% CI −4.46 to –0.51 and p<0.001; RCTs: SMD −0.67, 95% CI −0.89 to –0.44 and p<0.001). There was no evidence to prove that APD was associated with a higher incidence of infectious complications. However, the incidence of organ dysfunction between cohort studies and RCTs subgroup slightly differed (cohort studies: OR 0.66, 95% CI 0.34 to 1.28 and p=0.22; RCTs: OR 0.58, 95% CI 0.35 to 0.98 and p=0.04).ConclusionsThe findings suggest that early application of APD in patients with AP is associated with reduced all-cause mortality, expenses during hospitalisation and the length of stay compared with the ‘step-up’ strategy without significantly increasing the risk of infectious complications. These results must be interpreted with caution because of the limited number of included studies as well as a larger dependence on observational trials.PROSPERO registration numberCRD42020168537.

Anterior Cruciate

Background: Anterior cruciate ligament (ACL) ruptures are common, but the ideal timing for ACL reconstruction after injury is unclear with regard to meniscal insult. Purpose: To determine whether there is a relationship between timing from ACL rupture to ACL reconstruction and development of meniscal tears within this period. Study Design: Systematic review and meta-analysis. Methods: A systematic literature search was undertaken independently by 2 reviewers using the Cochrane method for systematic reviews in 5 online databases. The reviewers performed independent data extraction and assessment of risk of bias and study quality. The search included any comparative study, including randomized controlled trials (RCTs), prospective and retrospective cohort studies, and case-control studies of an adult population, that assessed the relationship between timing of ACL reconstruction surgery and rates of meniscal tears. Results: After screening, 12 studies (No. of participants = 3042) out of 3390 records were included for analysis: 3 RCTs (n = 272), 2 prospective cohort studies (n = 307), and 7 retrospective cohort studies (n = 2463). In analysis of these studies, rates of reported meniscal tears were compared for ACL procedures performed at 3 and 6 months after injury. Meta-analysis of 5 studies (n = 2012) showed that ACL reconstruction performed >3 months after injury was associated with a higher rate of medial meniscal tears compared with ACL reconstruction performed within 3 months of injury (estimated OR, 2.235; 95% CI, 1.183-4.223; P = .013) but not with a higher rate of lateral meniscal tears. Similarly, meta-analysis of 4 studies (n = 990) showed that ACL reconstruction performed >6 months after injury was associated with a higher rate of medial meniscal tears compared with ACL reconstruction performed within 6 months of injury (estimated OR, 2.487; 95% CI, 1.241-4.984; P = .01) but not with a higher rate of lateral meniscal tears. Conclusion: Our results suggest that delay of ACL reconstruction surgery >3 months after injury is associated with a higher rate of medial meniscal tears within this prereconstruction time frame. Further high-quality prospective studies may help determine whether this is a causal effect. However, based on current evidence, in those patients for whom ACL reconstruction is indicated, ACL reconstruction within 3 months of injury may be recommended.

BACKGROUND: Intrawound treatments have been reported to have favorable efficacy for preventing surgical site infection (SSI); however, the best strategy remains unknown. OBJECTIVE: The aim of this systematic review and network meta-analysis was to evaluate the efficacy of intrawound treatments to prevent SSI after spine surgery. STUDY DESIGN: A systematic review and network meta-analysis. METHODS: We searched the Cochrane Library, EMbase, PubMed, Chinese Science and Technology Periodical Database (VIP), China National Knowledge Infrastructure (CNKI), and Wanfang Data from the date of inception to March 2, 2020. The randomized controlled trials (RCTs) and cohort studies were identified and extracted by 2 reviewers independently. We performed a traditional pairwise meta-analysis to evaluate overall efficacy of intrawound treatments. Meanwhile, a network meta-analysis was performed to compare and rank the treatment efficacy using frequentist approach. RESULTS: Thirty-three publications (6 RCTs and 27 retrospective cohort studies) were included, involving 22,763 patients. For pairwise meta-analysis, the combined results showed that the intrawound treatment had a significantly lower SSI rate than the control group (CG) (odds ratio [OR] = 0.41; 95% confidence interval [CI], 0.31–0.55). For network meta-analysis, the treatment of vancomycin (VA) (OR = 0.53; 95% CI, 0.39-0.71), povidone-iodine (PI) (OR = 0.10; 95% CI, 0.04 - 0.23), and vancomycin + povidone-iodine (VA+PI) (OR = 0.25; 95% CI, 0.11-0.58) were found to be significantly more efficacious than CG on reduction of SSI rate. PI ranked first on reducing SSI, followed by PI+HP, VA+PI, gentamicin (GM), VA, and hydrogen peroxide (HP); CG ranked last. LIMITATIONS: Firstly, only 6 RCTs are included in this systematic review. Retrospective cohort studies tend to exaggerate the real results, although most of them are high-quality according to the Newcastle-Ottawa Quality Assessment Scale (NOQAS). More high-quality RCTs need to be included to obtain convincing conclusions. Secondly, the population of this study involves both adult and pediatric cohorts, patients with tumor, congenital disease, or degenerative disease. There is no subgroup analysis for ages and type of diseases, which might have influence on the overall pooled analysis. Thirdly, we define the application of saline solution and no intrawound treatment as the control group, which might ignore their heterogeneity. Fourthly, follow-up periods are variable and the sample size of HP is small. Finally, additional research is needed to compare the complications of different treatments and the benefits of various dosages. CONCLUSION: We found that VA and PI show promising results on reducing SSI. PI is recommended as the most efficacious intrawound treatment to prevent SSI after spine surgery.
