Introduction. Common femoral endarterectomy (CFE) has been the therapy of choice for common femoral artery atherosclerotic disease (CFA-ASD). In the past, there was inhibition to treat CFA-ASD endovascularly with stents due to fear of stent fracture and compromise of future vascular access site. However, recent advances and new evidence suggest that CFA may no longer be a ‘stent-forbidden zone’. In the light of new evidence, we conducted a meta-analysis to determine the use of endovascular treatment for CFA-ASD and compare it with common femoral endarterectomy in the present era.Methods. Using certain MeSH terms we searched multiple databases for studies done on endovascular and surgical treatment of CFA-ASD in the last two decades. Inclusion criteria were randomized control trials, observational, prospective, or retrospective studies evaluating an endovascular treatment or CFE for CFA-ASD. For comparison, studies were grouped based on the treatment strategy used for CFA-ASD: endovascular treatment with selective stenting (EVT-SS), endovascular treatment with routine stenting (EVT-RS), or common femoral endarterectomy (CFE). Primary patency (PP), target lesion revascularization (TLR), and complications were the outcomes studied. We did proportional meta-analysis using a random-effect model due to heterogeneity among the included studies. If confidence intervals of two results do not overlap, then statistical significance is determined.Results. Twenty-eight studies met inclusion criteria (7 for EVT-RS, 8 for EVT-SS, and 13 for CFE). Total limbs involved were 2914 (306 in EVT-RS, 678 in EVT-SS, and 1930 in CFE). The pooled PP at 1 year was 84% (95% CI 75-92%) for EVT-RS, 78% (95% CI 69-85%) for EVT-SS, and 93% (95% CI 90-96%) for CFE. PP at maximum follow-up in EVT-RS was 83.7% (95% CI 74-91%) and in CFE group was 88.3% (95% CI 81-94%). The pooled target lesion revascularization (TLR) rate at one year was 8% (95% CI 4-13%) for EVT-RS, 19% (95% CI 14-23%) for EVT-SS, and 4.5% (95% CI 1-9%) for CFE. The pooled rate of local complications for EVT-RS was 5% (95% CI 2-10%), for EVT-SS was 7% (95% CI 3 to 12%), and CFE was 22% (95% CI 14-32%). Mortality at maximum follow-up in CFE group was 23.1% (95% CI 14-33%) and EVT-RS was 5.3% (95% CI 1-11%).Conclusion. EVT-RS has comparable one-year PP and TLR as CFE. CFE showed an advantage over EVT-SS for one-year PP. The complication rate is lower in EVT RS and EVT SS compared to CFE. At maximum follow-up, CFE and EVT-RS have similar PP but CFE has a higher mortality. These findings support EVT-RS as a management alternative for CFA-ASD.

6596 Background: Several previous systematic reviews and meta-analyses have attempted to summarize toxicity of Immune checkpoint inhibitors (ICIs). However, very soon after each one of these reviews has been published, it became outdated. ICIs are currently used in 14 different cancers and data is rapidly evolving from new clinical trials. A living Systematic review, which is defined as a systematic review that is continually updated to incorporate relevant new evidence as it becomes available, is necessary in this situations. Therefore, we performed an updated systematic review and a meta-analysis which will serve as a foundation of a living Systematic review. Methods: MEDLINE, EMBASE and Cochrane were searched to identify phase 2 and 3 RCTs of PD-1/PD-L1 ICIs. Included studies compared either immunotherapy alone or combination with existing standard of care treatment and reported data for AE’s of interest. DerSimonian-Laird random effects Meta-Analysis was performed to derive pooled odds Ratio (OR) estimates for AE’s of interest. An infrastructure of a living systematic review is being developed and it includes monthly literature searches, cumulative meta-analysis and an online reporting platform. Results: We screened 6746 studies and 31 phase 3 and 2 phase 2 RCTs (n = 21,421) were included in the analysis. 22 RCTs used PD-1/PD-L1 ICIs as a single agent and 11 as a combination therapy. Selected toxicity estimates are summarized in a table. Conclusions: The meta-analysis updates previously published toxicity estimates and provides additional information about the risk of toxicities in single versus combination regimens. We have initiated the first living systematic review in oncology that will be continuously updated, incorporating relevant new evidence as it becomes available, and will provide accurate and up to date toxicity estimates to support clinical decision making.

Age-related macular degeneration (AMD) is the most common cause of blindness in elderly people worldwide and the major degenerative disease of the retina that leads to progressive impairment of central vision. Several polymorphisms in different genes have been proposed as factors that increase the disease susceptibility. The aim of the present study is to carry out a systematic review and an updated meta-analysis in order to summarize the current published studies and to evaluate the associations between four common vascular endothelial growth factor (VEGF) polymorphisms (rs833061, rs1413711, rs3025039, and rs2010963) and AMD risk, also stratifying for AMD subtypes and ethnicity. A systematic literature search in the Medline database, using PubMed, was carried out for epidemiological studies, published before June 2016. Associations ofVEGFpolymorphisms with AMD were estimated by calculating pooled odds ratios (ORs) and 95% confidence intervals (95% CIs) based on different models. Twelve articles were included in the analysis. The present meta-analysis constitutes a useful guide for readers to study AMD and adds new evidence to the growing literature on the role ofVEGFpolymorphisms in the risk of AMD. Significant associations with AMD risk were showed for rs833061, rs1413711, and rs3025039 polymorphisms but not for rs2010963.

INTRODUCTION Gallbladder cancer is the most common malignancy of the biliary tract. Given the lack of therapeutic alternatives for advanced stage patients studies have suggested that palliative chemotherapy could benefit these patients. METHODS We searched in Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis, and generated a summary of findings table using the GRADE approach. RESULTS AND CONCLUSIONS We identified two systematic reviews including two studies overall, of which one was a randomized trial. We concluded that palliative chemotherapy may increase survival in advanced gallbladder cancer patients. However, palliative chemotherapy probably increases adverse effects. In addition, it is essential to carry out a new systematic review, since methodological errors were identified in the analysis and there is new evidence that has not been included in the previous reviews

ABSTRACT Recent data from an individual patient data (IPD) meta-analysis of 17 randomized control trials including >100,000 women living in low- and middle-income countries found that multiple micronutrient supplementation (MMS) in pregnancy reduced the risk of low birth weight, preterm birth, and being born small for gestational age. Further, MMS reduced the risk of neonatal and infant mortality for females, and there was no evidence of increased risk among the 26 subgroups examined. The 2016 WHO antenatal care guidelines, which were released before the IPD meta-analysis, did not universally recommend MMS, noting: “There is some evidence of additional benefit … but there is also some evidence of risk.” The guidelines suggest that MMS may increase the risk of neonatal mortality based on an exploratory subgroup analysis of 6 randomized trials. However, we identified several issues with this subgroup analysis. In this report we correct and update the subgroup analysis and show that there is no evidence that MMS increases the risk of neonatal mortality. There is growing scientific consensus that MMS containing iron and folic acid (IFA) is superior to IFA alone. The WHO guidelines currently state that “policy-makers in populations with a high prevalence of nutritional deficiencies might consider the benefits of MMN [multiple micronutrient] supplements on maternal health to outweigh the disadvantages, and may choose to give MMN supplements that include iron and folic acid.” This equivocal guidance has created confusion about the best course of action for public health programs in low- and middle-income countries. Given the new evidence, WHO should review their statements regarding the potential neonatal mortality risks and re-evaluate the overall potential benefits of implementing MMS as a public health program.

OBJECTIVES: To update a previous clinical practice guideline on suctioning in adult patients, published in theCanadian Respiratory Journalin 2001.METHODS: A primary search of the MEDLINE (from 1998), CINAHL, EMBASE and The Cochrane Library (all from 1996) databases up to November 2007, was conducted. These dates reflect the search limits reached in the previous clinical practice guideline. A secondary search of the reference lists of retrieved articles was also performed. Two reviewers independently appraised each study before meeting to reach consensus. Study quality was evaluated using the Jadad and PEDro scales. When sufficient data were available, a meta-analysis was conducted using a random effects model. Data are reported as ORs, weighted mean differences and 95% CIs. When no comparisons were possible, qualitative analyses of the data were completed.RESULTS: Eighty-one studies were critically appraised from a pool of 123. A total of 28 randomized controlled trials or randomized crossover studies were accepted for inclusion. Meta-analysis was possible for open versus closed suctioning only. Recommendations from 2001 with respect to hyperoxygenation, hyperinflation, use of a ventilator circuit adaptor and subglottic suctioning were confirmed. New evidence was identified with respect to indications for suctioning, open suction versus closed suction systems, use of medications and infection control.CONCLUSIONS: While new evidence continues to be varied in strength, and is still lacking in some areas of suctioning practice, the evidence base has improved since 2001. Members of the health care team should incorporate this evidence into their practice.
