OBJECTIVESurgery is the definitive treatment of Chiari malformation Type I (CM-I). It involves posterior fossa decompression, which can be performed along with C-1 laminectomy, reconstructive duraplasty, or tonsil shrinkage. The aim of this study was to provide an updated systematic review and meta-analysis of the latest available evidence regarding posterior fossa decompression only (PFDO) versus posterior fossa decompression with duraplasty (PFDD) in the treatment of CM-I in children.METHODSA literature search was performed in compliance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines for article identification, screening, eligibility, and inclusion. Relevant articles were identified from 6 electronic databases from their inception to April 2016. These articles were screened against established criteria for inclusion into this study.RESULTSFrom 12 relevant studies identified, 1492 pediatric patients treated via PFDD were compared with 1963 pediatric patients treated by PFDO for CM-I. PFDD was associated with greater overall clinical improvement (p = 0.009), along with longer length of stay (p < 0.0001) and more postoperative complications (p = 0.0001) compared with PFDO. No difference was observed between PFDD and PFDO in terms of revision surgery incidence (p = 0.13), estimated blood loss (p = 0.14), syrinx improvement (p = 0.09), or scoliosis improvement (p = 0.95).CONCLUSIONSIt appears that the addition of duraplasty to posterior decompression in the definitive treatment of CM-I in children may alter surgical and performance outcomes. In particular, parameters of overall clinical improvement, length of stay, and postoperative complication may differ between children undergoing PFDD and those undergoing PFDO. Current evidence in the literature is of low to very low quality that, as of yet, has not been able to completely control for inherent selection bias both in study design and surgeon preference. Future, large prospective registries and randomized controlled trials are warranted to validate the findings of this study.

And Performance

Alliance experience has been a frequent topic in strategic alliance research in recent decades. Nonetheless, its performance consequences, either as a whole or differentiated into general versus partner-specific alliance experience, are neither theoretically clear nor empirically consistent. We use a range of meta-analytic techniques to integrate the empirical findings of 143 studies and provide a more conclusive assessment compared to prior research. Our study thus addresses a long-standing, understudied, and controversial topic: the distinction between the two types of alliance experiences. Going beyond traditional sub-group analysis, we reveal the contextual contingencies by examining how different types of alliance experiences and performance outcomes jointly affect the alliance experience–performance relationship. Moreover, we identify critical country-level institutional contingencies that moderate the focal effect.

Alliance Portfolios

Given the increasing interest in alliance portfolios, alliance portfolio diversity (APD) has been the focus of many recent studies. Yet, the performance consequences of APD—or of diversity in general—are neither theoretically clear nor empirically consistent. With meta-analytic analyses, we assess extant research on the APD–performance link. Across studies, APD has a positive impact on performance, although the level of analysis and how performance is measured influence the relationship. Going beyond conventional quantitative synthesis, however, we also systematically uncover patterns in how theoretical orientation and the operationalization of diversity moderate the APD–performance relationship. Our study serves as an invitation for future APD studies to employ more sophisticated theoretical and operationalization approaches as they expand our knowledge of diversity in alliance portfolios.

The Impact

Abstract Background Eating disorders (ED) can reduce quality of life by limiting participation and performance in social and occupational roles, including paid or unpaid work. The association between ED pathologies and work participation and performance must be well understood to strengthen vocational rehabilitation programmes and prevent occupational disruptions in the ED population. The aims of this study are: (1) to examine the degree of association between ED pathologies and work participation and performance in 15-year-olds and older; (2) to highlight the specific ED symptoms that are most correlated with changes in work performance and participation; (3) to compile the most common metrics and assessments used to measure work participation and performance with ED. Methods Medline, Embase, CINAHL, Web of Science, PsycINFO, and Cochrane Library will be searched for observational and experimental studies that meet the following criteria: (1) a clinical sample of typical or atypical ED; (2) paid or unpaid employment or training; (3) an association between ED pathologies and work participation or performance. Unpublished data will also be examined. Title and abstract, and full-text screening will be conducted in duplicate. Risk of bias and quality of evidence assessments will be completed. A random-effect meta-analysis will be performed. Discussion This synthesis can clarify knowledge and gaps around the impact of ED on work functioning, thereby allowing better evaluation, improvements and development of current workplace assessments, interventions, and policies. Trial registration The registration number for this systematic review on PROSPERO is CRD42021255055.

Background and aims: A high rate of neoplasia (high grade dysplasia; HGD and esophageal adenocarcinoma; EAC) has been reported in Barrett’s Esophagus at index endoscopy but precise rates of post endoscopy Barrett’s neoplasia (PEBN) are unknown. Methods: Systematic review and meta-analysis was performed examining electronic databases (inception to October 2021) for studies reporting PEBN. Consistent with definitions of Post Colonoscopy Colorectal Cancer as proposed by the World Endoscopy Organization, we defined neoplasia(HGD/EAC) detected at index endoscopy and/or within 6 months of a negative index endoscopy as “prevalent” neoplasia; those detected after 6 months of a negative index endoscopy and prior to next surveillance interval(i.e. 3 years) as PEBN or “interval” neoplasia, and those detected after 36 months of a negative index endoscopy as “incident” neoplasia. Pooled incidence rates and proportion relative to total neoplasia were analyzed. Results: 11 studies (n=59,795, age:62.3±3.3 years, 61%males) met inclusion criteria. The pooled incidence rates were: prevalent neoplasia 4.5% (95%confidence interval: 2.2-8.9) at baseline and additional 0.3%(0.1-0.7) within first 6 months, PEBN 0.52%(0.48-0.58) and incident neoplasia: 1.41%(0.93-2.14). At 3 years from index endoscopy, PEBN accounted for 3% while prevalent neoplasia accounted for 97% of total Barrett’s neoplasia. Conclusion: Neoplasia detected at or within 6 months of index endoscopy account for most of the Barrett’s neoplasia(>90%). Post-Endoscopy Barrett’s Neoplasia account for ~3% of cases and can be used for validation in future. This highlights the importance of a high-quality index endoscopy in Barrett’s Esophagus and the need to establish quality benchmarks to measure endoscopists’ performance.

The Relationship

The importance of learning transfer in ensuring that learning contributes to an organization's competitive advantage has been undermined in organizational practice. There are two major reasons for this: 1) few studies directly explore the relationship between transfer and performance improvement, and 2) most existing transfer models are too complex for practitioners to implement. The purpose of this chapter is to explore the link between learning transfer activities and performance outcomes, and to create a framework for implementing an effective learning transfer solution. A targeted literature review meta-analysis was used to explore the performance impact of training vs. training plus transfer activities. The authors compute “difference scores” representing the percentage of improvement from the transfer activities over training alone. Activities are categorized into a framework of eleven critical learning transfer actions. They then implement the elements of the Learning Transfer Framework in three demonstration projects. By incorporating findings from the literature review, meta-analysis, and the demonstration projects, the authors propose a new transfer framework that is effective and easy to implement. Implications and directions for future researchers are advanced.
