Abstract Background Although shorter lengths of Barrett’s esophagus (BE) have been associated with a lower risk of neoplastic progression, precise estimates have varied, especially for non-dysplastic BE (NDBE) only. Therefore, current US guidelines do not provide specific recommendations on surveillance intervals based on BE length. We performed a systematic review and meta-analysis of the published literature to examine neoplastic progression rates of NDBE based on BE length. Methods PubMed, Cochrane, Google Scholar, and Embase were comprehensively searched. Studies reporting progression rates in patients with NDBE and > 1 year of follow-up were included. The number of patients progressing to esophageal adenocarcinoma (EAC) and high grade dysplasia (HGD)/EAC in individual studies and the mean follow-up were recorded to derive person-years of follow-up. Pooled rates of progression to EAC and HGD/EAC based on BE length (< 3 cm vs. ≥ 3 cm) were calculated. Results Of the 486 initial studies identified, 10 met the inclusion/exclusion criteria. These included a total of 4097 NDBE patients; 1979 with short-segment BE (SSBE; 10 773 person-years of follow-up) and 2118 with long-segment BE (LSBE; 12 868 person-years). The annual rates of progression to EAC were significantly lower for SSBE compared with LSBE: 0.06 % (95 % confidence interval 0.01 % – 0.10 %) vs. 0.31 % (0.21 % – 0.40 %), respectively; odds ratio (OR) 0.25 (0.11 – 0.56); P < 0.001, as were the rates for the combined endpoint (HGD/EAC): 0.24 % (0.09 % – 0.32 %) vs. 0.76 % (0.43 % – 0.89 %), respectively; OR 0.35 (0.21 – 0.58); P < 0.001. There was no significant heterogeneity among studies. Conclusion The results demonstrate significantly lower rates of neoplastic progression in NDBE patients with SSBE compared with LSBE. BE length can easily be used for risk stratification purposes for NDBE patients undergoing surveillance endoscopy and consideration should be given to tailoring surveillance intervals based on BE length in future US guidelines.

Abstract Background Barrett’s esophagus (BE) is a premalignant condition characterized by replacement of the esophageal lining with metastatic columnar epithelium, and its management when complicated by low grade dysplasia (LGD) is controversial. This systematic review and meta-analysis aimed to determine the efficacy of radiofrequency ablation (RFA) in patients with LGD. Methods MEDLINE, EMBASE, and Web of Science were searched for studies including patients with BE-associated LGD receiving RFA (January 1990 to May 2017). The outcome measures were complete eradication of intestinal metaplasia (CE-IM) and dysplasia (CE-D), rates of progression to high grade dysplasia (HGD) or cancer, and recurrence. Results Eight studies including 619 patients with LGD (RFA = 404, surveillance = 215) were analyzed. After a median follow-up of 26 months (range 12 – 44 months), the overall pooled rates of CE-IM and CE-D after RFA were 88.17 % (95 % confidence interval [CI] 88.13 % – 88.20 %; P < 0.001) and 96.69 % (95 %CI 96.67 % – 96.71 %; P < 0.001), respectively. When compared with surveillance, RFA resulted in significantly lower rates of progression to HGD or cancer (odds ratio [OR] 0.07, 95 %CI 0.02 – 0.22). The pooled recurrence rates of IM and dysplasia were 5.6 % (95 %CI 5.57 – 5.63; P < 0.001) and 9.66 % (95 %CI 9.61 – 9.71; P < 0.001), respectively. Conclusions RFA safely eradicates IM and dysplasia and reduces the rates of progression from LGD to HGD or cancer in the short term.

Summary It is known that Barrett’s esophagus (BE) and esophageal adenocarcinoma occur more commonly in men. What is unknown are the prevalence of BE and rates of neoplastic progression in women. Our aim was to determine the prevalence of Barrett’s and its progression to esophageal cancer in women through systematic review and meta-analysis. A comprehensive search was conducted using PubMed, Scopus, and Google Scholar. Studies were included that reported prevalence rates of BE or progression rates to neoplastic disease stratified by gender. Barrett’s was defined by updated criteria as salmon-colored mucosa ≥1 cm proximal to the gastroesophageal junction. Pooled rates and odds ratios (ORs) at 95% confidence interval (CI) of the prevalence of BE and its progression to neoplastic disease were calculated. Ten studies with 19,337 patients (50.6% women) reported on prevalence and six studies with 5137 patients (24.3% women) reported on neoplastic progression of disease between genders. The rate of BE in women was 1.29% ([95% CI: 0.76–2.19], I2 = 91%) compared to men at 4.66% ([95% CI: 3.31–6.53], I2 = 89%); OR: 0.33 ([95% CI: 0.27–0.42], I2 = 0%). The rate of annual progression of Barrett’s to high-grade dysplasia or adenocarcinoma was 0.62% ([95% CI: 0.22–1.75]) in women compared to 1.54% ([95% CI: 0.83–2.81], I2 = 96%) in men; OR: 0.44 ([95% CI: 0.30–0.65], I2 = 22%). This study demonstrates a 70% lower rate of prevalence and a 60% lower rate of neoplastic progression of Barrett’s in women. Future BE guidelines should tailor screening and surveillance practices by gender.

Abstract Purpose The purpose of this study was to perform a systematic review of the reparticipation in sport at mid-term follow up in athletes who underwent biologic treatment of chondral defects in the knee and compare the rates amongst different biologic procedures. Methods A search of PubMed/Medline and Embase was performed in May 2020 in keeping with Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. The criteria for inclusion were observational, published research articles studying the outcomes and rates of participation in sport following biologic treatments of the knee with a minimum mean/median follow up of 5 years. Interventions included microfracture, osteochondral autograft transfer (OAT), autologous chondrocyte implantation (ACI), matrix-induced autologous chondrocyte implantation (MACI), osteochondral allograft, or platelet rich plasma (PRP) and peripheral blood stem cells (PBSC). A random effects model of head-to-head evidence was used to determine rates of sporting participation following each intervention. Results There were twenty-nine studies which met the inclusion criteria with a total of 1276 patients (67% male, 33% female). The mean age was 32.8 years (13–69, SD 5.7) and the mean follow up was 89 months (SD 42.4). The number of studies reporting OAT was 8 (27.6%), ACI was 6 (20.7%), MACI was 7 (24.1%), microfracture was 5 (17.2%), osteochondral allograft was 4 (13.8%), and one study (3.4%) reported on PRP and PBSC. The overall return to any level of sport was 80%, with 58.6% returning to preinjury levels. PRP and PBSC (100%) and OAT (84.4%) had the highest rates of sporting participation, followed by allograft (83.9%) and ACI (80.7%). The lowest rates of participation were seen following MACI (74%) and microfracture (64.2%). Conclusions High rates of re-participation in sport are sustained for at least 5 years following biologic intervention for chondral injuries in the knee. Where possible, OAT should be considered as the treatment of choice when prolonged participation in sport is a priority for patients. However, MACI may achieve the highest probability of returning to the same pre-injury sporting level. Level of evidence IV
