| 8 | Gastric intestinal metaplasia development in African American predominant United States population显示文摘BACKGROUND Gastric cancer significantly contributes to cancer mortality globally.Gastric intestinal metaplasia(GIM)is a stage in the Correa cascade and a premalignant lesion of gastric cancer.The natural history of GIM formation and progression over time is not fully understood.Currently,there are no clear guidelines on GIM surveillance or management in the United States.AIM To investigate factors associated with GIM development over time in African American-predominant study population.METHODS This is a retrospective longitudinal study in a single tertiary hospital in Washington DC.We retrieved upper esophagogastroduodenoscopies(EGDs)with gastric biopsies from the pathology department database from January 2015 to December 2020.Patients included in the study had undergone two or more EGDswith gastric biopsy.Patients with no GIM at baseline were followed up until they developed GIM or until the last available EGD.Exclusion criteria consisted of patients age<18,pregnancy,previous diagnosis of gastric cancer,and missing data including pathology results or endoscopy reports.The study population was divided into two groups based on GIM status.Univariate and multivariate Cox regression was used to estimate the hazard induced by patient demographics,EGD findings,and Helicobacter pylori(H.pylori)status on the GIM status.RESULTS Of 2375 patients who had at least 1 EGD with gastric biopsy,579 patients were included in the study.138 patients developed GIM during the study follow-up period of 1087 d on average,compared to 857 d in patients without GIM(P=0.247).The average age of GIM group was 64 years compared to 56 years in the non-GIM group(P<0.001).In the GIM group,adding one year to the age increases the risk for GIM formation by 4%(P<0.001).Over time,African Americans,Hispanic,and other ethnicities/races had an increased risk of GIM compared to Caucasians with a hazard ratio(HR)of 2.12(1.16,3.87),2.79(1.09,7.13),and 3.19(1.5,6.76)respectively.No gender difference was observed between the study populations.Gastritis was associated with an increased risk for GIM development with an HR of 1.62(1.07,2.44).On the other hand,H.pylori infection did not increase the risk for GIM.CONCLUSION An increase in age and non-Caucasian race/ethnicity are associated with an increased risk of GIM formation.The effect of H.pylori on GIM is limited in low prevalence areas. | Akram I Ahmad Arielle Lee Claire Caplan Colin Wikholm Ioannis Pothoulakis Zaynab Almothafer NishthaRaval Samantha Marshall Ankit Mishra Nicole Hodgins In Guk Kang Raymond K Chang Zachary Dailey Arvin Daneshmand Anjani Kapadia Jae Hak Oh Brittney Rodriguez Abhinav Sehgal Matthew Sweeney Christopher B Swisher Daniel F Childers Corinne O'Connor Lynette M Sequeira Won Cho | 2022 | World Journal of Gastrointestinal Endoscopy2022，14，10： | 1 |

| 13 | Trends in leadership at orthopaedic surgery sports medicine fellowships显示文摘BACKGROUND Fellowship directors(FDs)in sports medicine influence the future of trainees in the field of orthopaedics.Understanding the characteristics these leaders share must be brought into focus.For all current sports medicine FDs,our group analyzed their demographic background,institutional training,and academic experience.AIM To serve as a framework for those aspiring to achieve this position in orthopaedics and also identify opportunities to improve the position.METHODS Fellowship programs were identified using both the American Orthopaedic Society for Sports Medicine and the Arthroscopy Association of North America Sports Medicine Fellowship Directories.The demographic and educational background data for each FD was gathered via author review of current curriculum vitae(CVs).Any information that was unavailable on CV review was gathered from institutional biographies,Scopus Web of Science,and emailed questionnaires.To ensure the collection of as many data points as possible,fellowship program coordinators,orthopaedic department offices and FDs were directly contacted via phone if there was no response via email.Demographic information of interest included:Age,gender,ethnicity,residency/fellowship training,residency/fellowship graduation year,year hired by current institution,time since training completion until FD appointment,length in FD role,status as a team physician and H-index.RESULTS Information was gathered for 82 FDs.Of these,97.5%(n=80)of the leadership were male;84.15%(n=69)were Caucasian,7.32%(n=6)were Asian-American,2.44%(n=2)were Hispanic and 2.44%(n=2)were African American,and 3.66%(n=3)were of another race or ethnicity.The mean age of current FDs was 56 years old(±9.00 years),and the mean Scopus H-index was 23.49(±16.57).The mean calendar years for completion of residency and fellowship training were 1996(±15 years)and 1997(±9.51 years),respectively.The time since fellowship training completion until FD appointment was 9.77 years.17.07%(n=14)of FDs currently work at the same institution where they completed residency training;21.95%(n=18)of FDs work at the same institution where they completed fellowship training;and 6.10%(n=5)work at the same institution where they completed both residency and fellowship training.Additionally,69.5%(n=57)are also team physicians at the professional and/or collegiate level.Of those that were found to currently serve as team physicians,56.14%(n=32)of them worked with professional sports teams,29.82%(n=17)with collegiate sports teams,and 14.04%(n=8)with both professional and collegiate sports teams.Seven residency programs produced the greatest number of future FDs,included programs produced at least three future FDs.Seven fellowship programs produced the greatest number of future FDs,included programs produced at least four future FDs.Eight FDs(9.75%)completed two fellowships and three FDs(3.66%)finished three fellowships.Three FDs(3.66%)did not graduate from any fellowship training program.The Scopus H-indices for FDs are displayed as ranges that include 1 to 15(31.71%,n=26),15 to 30(34.15%,n=28),30 to 45(20.73%,n=17),45 to 60(6.10%,n=5)and 60 to 80(3.66%,n=3).Specifically,the most impactful FD in research currently has a Scopus H-index value of 79.By comparison,the tenth most impactful FD in research had a Scopus H-index value of 43(accessed December 1,2019).CONCLUSION This study provides an overview of current sports medicine FDs within the United States and functions as a guide to direct initiatives to achieve diversity equality. | Nicholas C Schiller Andrew J Sama Amanda F Spielman Chester J Donnally III Benjamin I Schachner Dhanur M Damodar Christopher C Dodson Michael G Ciccotti | 2021 | World Journal of Orthopedics2021，12，6： | 0 |
| 14 | Pre-transplant treatment of large polycystic kidney显示文摘AIM: To evaluate the indications, optimal timing andoutcomes of native nephrectomy and other techniques in pretransplant treatment of autosomal dominant polycystic kidney disease(PKD).METHODS: A literature review was conducted using the Pub Med and Epistemonikos databases. Keywords for pre-transplant surgical management of polycystic kidneys were: Transplant, treatment and PKD. Keywords for pre-treatment embolization of PKD were: Embolization, transplant and polycystic kidney disease. The inclusion criterions were all articles found using this search method. The exclusion criterions were articles found to include bias and not attending pre-transplant treatment options. Fifteen articles were included in our final analysis. Ten articles were found regarding embolization of PKD of which three reviews were selected for final analysis. The reviews were divided into pre transplant and intra transplant treatment for the surgical treatment of PKD. All articles meeting inclusion criteria were thoroughly analyzed by two independent reviewers. A third independent reviewer was consulted if the reviewers did not agree upon the inclusion or exclusion of a specific article. No statistical analysis was performed.RESULTS: Studies vary regarding the technique used(open or laparoscopic), laterality(single or bilateral) and temporality of nephrectomy with respect to renal transplant(pre-transplant or simultaneous to transplant). Several groups argue in favor of simultaneous nephrectomy and kidney transplant since it avoids the deleterious effects of being anefric. Long-term results and patient satisfaction are acceptable. However, it is associated with increased operative time, transfusion rate, morbidity and length of hospital stay. Based on small sample studies, bilateral nephrectomy prior to transplant has been associated with a higher risk of morbidity and mortality. Studies on laparoscopic approach report it as a feasible and safe alternative to the open surgery approach, highlighting its lower complication rate, transfusions and shorter hospital stay. Arterial embolization of the kidney appears as an effectiveand low morbid alternative for the management of large native kidneys. The reduction in renal size allow transplant in a significant number of patients, which makes it an appealing alternative to surgery.CONCLUSION: There is limited evidence regarding best pretrasnplant treatment of large PKD but to date embolization seems an appealing alternative to augment space for renal graft allocation. | Iván D Sáez Juan F de la Llera Andrés Tapia Rodrigo A Chacón Pedro A Figueroa Bruno I Vivaldi Alfredo Domenech Christopher D Horn Fernando Coz | 2016 | World Journal of Clinical Urology2016，5，1： | 0 |
