| 1 | Duodenal gangliocytic paraganglioma with lymph node metastases: a case report and comparative review of 31 cases显示文摘Gangliocytic paraganglioma(GP) is a rare tumor of uncertain origin most often located in the second portion of the duodenum. It is composed of three cellular components: Epithelioid endocrine cells, spindlelike/sustentacular cells, and ganglion-like cells. While this tumor most often behaves in a benign manner, cases with metastasis are reported. We describe the case of a 62-year-old male with a periampullary GP with metastases to two regional lymph nodes who was successfully treated with pancreaticoduodenectomy. Using Pub Med, EMBASE, EBSCOhost MEDLINE and CINAHL, and Google Scholar, we searched the literature for cases of GP with regional lymph node metastasis and evaluated the varying presentations, diagnostic workup, and disease management of identified cases. Thirty-one cases of GP with metastasis were compiled(30 with at least lymph node metastases and one with only distant metastasis to bone), with age at diagnosis ranging from 16 to 74 years. Ratio of males to females was 19:12. The most common presenting symptoms were abdominal pain(55%) and gastrointestinal bleeding or sequelae(42%). Twenty-five patients underwent pancreaticoduodenectomy. Five patients were treated with local resection alone. One patient died secondary to metastatic disease, and one died secondary to perioperative decompensation. The remainder did well, with no evidence of disease at follow-up from the most recent procedure(except two in which residual disease was deliberately left behind). Of the 26 cases with sufficient histological description, 16 described a primary tumor that infiltrated deep to the submucosa, and 3 described lymphovascular invasion. Of the specific immunohistochemistry staining patterns studied, synaptophysin(SYN) stained all epithelioid endocrine cells(18/18). Neuron specific enolase(NSE) and SYN stained most ganglion-like cells(7/8 and 13/18 respectively), and S-100 stained all spindle-like/sustentacular cells(21/21). Our literature review of published cases of GP with lymph node metastasis underscores the excellent prognosis of GP regardless of specific treatment modality. We question the necessity of aggressive surgical intervention in select patients, and argue that local resection of the mass and metastasis may be adequate. We also emphasize the importance of pre-surgical assessment with imaging studies, as well as post-surgical follow-up surveillance for disease recurrence. | Sahara J Cathcart Aaron R Sasson Jessica A Kozel Jennifer M Oliveto Quan P Ly | 2017 | World Journal of Clinical Cases2017，5，6： | 9 |
| 2 | Restoring the gut microbiome for the treatment of inflammatory bowel diseases显示文摘Fecal microbiota transplantation(FMT)is considered to be a highly successful therapy for recurrent and refractory Clostridium difficile infection(CDI)based on recent clinical trials.The pathogenesis of inflammatory bowel diseases(IBD)is thought to be due in part to perturbations in the gut microflora that disrupt homeostasis.FMT restores essential components of the microflora which could reverse the inflammatory processes observed in IBD.Case reports and series for the treatment of IBD by FMT have shown promise with regards to treatment success and safety despite the limitations of the reporting.Future studies will determine the optimal delivery and preparation of stool as well as the conditions under which the recipient will derive maximal benefit.The long term consequences of FMT with regards to infection,cancer,auto-immune,and metabolic diseases are not known and will require continued regulation and study.Despite these limitations,FMT may be beneficial for the treatment of ulcerative colitis and Crohn’s disease,particularly those with concurrent CDI or with pouchitis. | Jessica R Allegretti Matthew J Hamilton | 2014 | World Journal of Gastroenterology2014，20，13： | 7 |

| 4 | Evaluation of the safety and effectiveness of direct oral anticoagulants and low molecular weight heparin in gastrointestinal cancer-associated venous thromboembolism显示文摘BACKGROUND Gastrointestinal cancer(GICA)is associated with a higher incidence of venous thromboembolism(VTE)compared to other solid tumors,moreover,recurrent VTE and major bleeding(MB)complications during anticoagulation treatment have an associated increase rate.GICA-VTE remains a challenging clinical scenario with MB concerns for utilization of direct oral anticoagulants(DOAC),especially with active cancer therapies.AIM To evaluate patient risk factors,effectiveness(VTE)and safety(MB)of DOACs and low molecular weight heparin(LMWH)in patients with active GICA-VTE.METHODS A retrospective chart review of patients receiving DOACs and LMWH with GICA and symptomatic or incidental VTE treated at comprehensive cancer center from November 2013 to February 2017 was performed.Inclusion criteria included active GI cancer diagnosed at any stage or treatment+/-6 mo of VTE diagnosis,whom were prescribed 6 mo or more of DOACs or LMWH.The Chi-squared test was used for overall and the Fisher exact test for pairwise comparisons of the proportions of patients experiencing recurrent VTE and MB events.Odds ratios were used to compare the relative odds of the occurrence of the outcome given exposure to the risk factor.RESULTS A total of 144 patients were prescribed anticoagulation,in which 106 fulfilled inclusion criteria apixaban(27.3%),rivaroxaban(34.9%)and enoxaparin(37.7%),and 38 were excluded.Patients median age was 66.5 years at GICA diagnosis and 67 years at CAVTE event,with 62%males,80%Caucasian,70%stage IV,pancreatic cancer(40.5%),30%Khorana Score(≥3 points),and 43.5%on active chemotherapy.Sixty-four percent of patients completed anticoagulation therapy(range 1 to 43 mo).Recurrent VTE at 6 mo was noted in 7.5%(n=3),6.8%(n=2)and 2.7%(n=1)of patients on enoxaparin,apixaban and rivaroxaban,respectively(all P=NS).MB at 6 mo were 5%(n=2)for enoxaparin,6.8%(n=2)for apixaban and 21.6%(n=8)for rivaroxaban(overall P=0.048;vs LMWH P=0.0423;all other P=NS).Significant predictors of a primary or secondary outcome for all anticoagulation therapies included:Active systemic treatment(OR=5.1,95%CI:1.3-19.3),high Khorana Score[≥3 points](OR=5.5,95%CI:1.7-17.1),active smoker(OR=6.7,95%CI:2.1-21.0),pancreatic cancer(OR=6.8,95%CI:1.9-23.2),and stage IV disease(OR=9.9,95%CI:1.2-79.1).CONCLUSION Rivaroxaban compared to apixaban and enoxaparin had a significantly higher risk of MB on GICA-VTE patients with equivocal efficacy. | Alejandro Recio-Boiles Sumana Veeravelli Jessica Vondrak Hani M Babiker Aaron J Scott Rachna T Shroff Hitendra Patel Emad Elquza Ali McBride | 2019 | World Journal of Gastrointestinal Oncology2019，11，10： | 3 |
| 5 | Update on novel endoscopic therapies to treat gastroesophageal reflux disease: A review显示文摘Endoscopic treatments for gastroesophageal reflux disease(GERD) have become increasingly popular in recent years. While surgical intervention with the Laparoscopic Nissen Fundoplication remains the gold standard, two endoscopic interventions, specifically, are gaining traction in clinical use(Esophy X and Stretta). The Esophy X(Endo Gastric Solutions, Inc., Redmond, WA, United States) was developed as a method of restoring the valve at the GE junction through an endoluminal fundoplication(ELF) technique. Long-term data suggests that transoral incisional fundoplication(TIF) with Esophy X may be effective for symptom control and proton pump inhibitor reduction or cessation for up to 2-6 years. There is no evidence that Esophy X is more effective than surgical intervention. TIF may be most effective for patients with HH < 2 cm and Hill Grade I/II valves. Stretta(Mederi Therapeutics, Greenwich, CT, United States) was approved by the Food and Drug Administration in 2000. It delivers radiofrequency energy to the lower esophageal sphincter and gastric cardia. Published reviews of the literature are conflicted in their recommendations of Stretta in the management of GERD. The literature suggests that the Stretta procedure has an acceptable safety profile and may be effective in reducing symptom burden and quality of life scores up to 8 years post-intervention. However, there does not appear to be any sustained improvement in objective outcomes and there is no evidence that Stretta results in improved outcomes as compared to surgical intervention. Treatment modalities for GERD, as a field, suffer from a lack of standardization in primary and secondary outcomes. Although many studies have looked at health related quality of life, the tools used to do so are markedly heterogeneous. Future directions for the endoscopic treatment of GERD include novel techniques like endoscopic submucosal dissection. | Jessica Hopkins Noah J Switzer Shahzeer Karmali | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，11： | 2 |
| 6 | Interferon-β induced in female genital epithelium by HIV-1 glycoprotein 120 via Toll-like-receptor 2 pathway acts to protect the mucosal barrier显示文摘More than 40%of HIV infections occur via female reproductive tract(FRT)through heterosexual transmission.Epithelial cells that line the female genital mucosa are the first line of defense against HIV-1 and other sexually transmitted pathogens.These sentient cells recognize and respond to external stimuli by induction of a range of carefully balanced innate immune responses.Previously,we have shown that in response to HIV-1 gp120,the genital epithelial cells(GECs)from upper reproductive tract induce an inflammatory response that may facilitate HIV-1 translocation and infection.In this study,we report that the endometrial and endocervical GECs simultaneously induce biologically active interferon-β(IFNβ)antiviral responses following exposure to HIV-1 that act to protect the epithelial tight junction barrier.The innate antiviral response was directly induced by HIV-1 envelope glycoprotein gp120 and addition of gp120 neutralizing antibody inhibited IFNβproduction.Interferon-βwas induced by gp120 in upper GECs through Toll-like receptor 2 signaling and required presence of heparan sulfate on epithelial cell surface.The induction of IFNβwas dependent upon activation of transcription factor IRF3(interferon regulatory factor 3).The IFNβwas biologically active,had a protective effect on epithelial tight junction barrier and was able to inhibit HIV-1 infection in TZM-bl indicator cells and HIV-1 replication in T cells.This is the first report that recognition of HIV-1 by upper GECs leads to induction of innate antiviral pathways.This could explain the overall low infectivity of HIV-1 in the FRT and could be exploited for HIV-1 prophylaxis. | Aisha Nazli Sara Dizzell Muhammad Atif Zahoor Victor H Ferreira Jessica Kafka Matthew William Woods Michel Ouellet Ali A Ashkar Michel J Tremblay Dawn ME Bowdish Charu Kaushic | 2019 | Cellular & Molecular Immunology2019，16，2： | 2 |
| 7 | Effect of hepatic artery embolization on liver hypertrophy response in a rabbit liver VX2tumor model显示文摘BACKGROUND:Portal vein embolization not only induces hypertrophy of the non-embolized liver,but also enhances tumor growth.The latter could be prevented by embolizing the hepatic arteries supplying the tumor-bearing liver segments.This study aimed to determine the effects of transcatheter arterial embolization(TAE)on tumor volume and liver regeneration in a rabbit VX2 tumor model.METHODS:Twenty-three rabbits underwent subcapsular tumor implantation with a VX2 tumor.Two weeks after implantation,18 rabbits were used for TAE experiments,5were for sham controls.Tumor response and liver regeneration response of the embolized cranial and non-embolized caudal liver lobes were assessed by CT volumetry,liver to body weight index,and the amount of proliferating hepatocytes.RESULTS:All super-selective arterial tumor embolization procedures were performed successfully.Despite embolization,the tumor volume increased after an initial steady state.The tumor volume after embolization was smaller than that of the sham group,but this difference was not significant.Massive necrosis of the tumor,however,was seen after embolization,without damage of the surrounding liver parenchyma.There was a significant atrophy response of the tumor bearing cranial lobe after super-selective arterial embolization of the tumor with a concomitant hypertrophy response of the non-embolized,caudal lobe.This regeneration response was confirmed histologically by a significantly higher number of proliferating hepatocytes on the Ki-67 stained slides.CONCLUSIONS:Super-selective,bland arterial coil embolization causes massive necrosis of the tumor,despite increase of volume on CT scan.Atrophy of the tumor bearing liver lobe is seen after arterial embolization of the tumor with a concomitant hypertrophy response of the non-embolized lobe,despite absence of histological damage of the tumor-surrounding liver parenchyma. | Krijn P van Lienden Lisette T Hoekstra Jessica D van Trigt Joris J Roelofs Otto M van Delden Thomas M van Gulik | 2013 | Hepatobiliary & Pancreatic Diseases International2013，12，6： | 2 |
| 8 | Procedural complexity independent of P2Y12 reaction unit(PRU)values is associated with acute in situ thrombosis in Pipeline flow diversion of cerebral aneurysms显示文摘background Acute in situ thrombosis is an ischaemic phenomenon during Pipeline embolisation device(PED)procedures with potentially high morbidity and mortality.There is controversy regarding the role of platelet function testing with P2Y12 assay as a predictor of intraprocedural thromboembolic events.There is limited knowledge on whether procedural complexity influences these events.Methods Data were collected retrospectively on 742 consecutive PED cases at a single institution.Patients with intraprocedural acute thrombosis were compared with patients without these events.results A cohort of 37 PED cases with acute in situ thrombosis(mean age 53.8 years,mean aneurysm size 8.4 mm)was matched with a cohort of 705 PED cases without intraprocedural thromboembolic events(mean age 56.4 years,mean aneurysm size 6.9 mm).All patients with in situ thrombosis received intra-arterial and/or intravenous abciximab.The two groups were evenly matched in patient demographics,previous treatment/subarachnoid hemorrhage(SAH)and aneurysm location.There was no statistical difference in postprocedural P2Y12 reaction unit(PRU)values between the two groups,with a mean of 156 in the in situ thrombosis group vs 148 in the control group(p=0.5894).Presence of cervical carotid tortuosity,high cavernous internal carotid artery grade,need for multiple PED and vasospasm were not significantly different between the two groups.The in situ thrombosis group had statistically significant longer fluoroscopy time(60.4 vs 38.4 min,p<0.0001),higher radiation exposure(3476 vs 2160 mGy,p<0.0001),higher rates of adjunctive coiling(24.3% vs 8.37%,p=0.0010)and higher utilisation of balloon angioplasty(37.8% vs 12.2%,p<0.0001).Clinically,the in situ thrombosis cohort had higher incidence of major and minor stroke,intracerebral haemorrhage and length of stay.Conclusions Predictors of procedural complexity(higher radiation exposure,longer fluoroscopy time,adjunctive coiling and need for balloon angioplasty)are associated with acute thrombotic events during PED placement,independent of PRU values. | Bowen Jiang Matthew T Bender Erick M Westbroek Jessica K Campos Li-Mei Lin Risheng Xu Rafael J Tamargo Judy Huang Geoffrey P Colby Alexander L Coon | 2018 | Stroke & Vascular Neurology2018，3，3： | 2 |
| 9 | A comparison of the relative efficiency of ICSI and extended culture with epididymal sperm versus testicular sperm in patients with obstructive azoospermia显示文摘This is a retrospective cohort study comparing blastocyst transfer outcomes following intracytoplasmic sperm injection utilizing epididymal versus testicular sperm for men with obstructive azoospermia.All cases at a single center between 2012 and 2016 were included.Operative approach was selected at the surgeon’s discretion and included microepididymal sperm aspiration or testicular sperm extraction.Blastocyst culture was exclusively utilized prior to transfer.The primary outcome was live birth rate.Secondary outcomes included fertilization rate,blastulation rate,euploidy rate,and implantation rate.A mixed effects model was performed.Seventy-six microepididymal sperm aspiration cases and 93 testicular sperm extraction cases were analyzed.The live birth rate was equivalent(48.6%vs 50.5%,P=0.77).However,on mixed effects model,epididymal sperm resulted in a greater likelihood of fertilization(adjusted OR:1.37,95%CI:1.05–1.81,P=0.02)and produced a higher blastulation rate(adjusted OR:1.41,95%CI:1.1–1.85,P=0.01).As a result,the epididymal sperm group had more supernumerary blastocysts available(4.3 vs 3,P<0.05).The euploidy rate was no different.Pregnancy rates were no different through the first transfer cycle.However,intracytoplasmic sperm injection following microepididymal sperm aspiration resulted in a greater number of usable blastocysts per patient.Thus,the true benefit of epididymal sperm may only be demonstrated via a comparison of cumulative pregnancy rates after multiple transfers from one cohort. | Scott J Morin Brent M Hanson Caroline R Juneau Shelby A Neal Jessica N Landis Richard T Scott Jr James M Hotaling | 2020 | Asian Journal of Andrology2020，22，2： | 2 |

| 11 | Glucocorticoid receptor gene haplotype structure and steroid therapy outcome in IBD patients显示文摘AIM: To study whether the glucocorticoid receptor (GR/ NR3C1) gene haplotypes influence the steroid therapy outcome in inflammatory bowel disease (IBD). METHODS: We sequenced all coding exons and flanking intronic sequences of the NR3C1 gene in 181 IBD patients, determined the single nucleotide polymorphisms, and predicted the NR3C1 haplotypes. Furthermore, we investigated whether certain NR3C1 haplotypes are significantly associated with steroid therapy outcomes. RESULTS: We detected 13 NR3C1 variants, which led to the formation of 17 different haplotypes with a certainty of > 95% in 173 individuals. The three most commonly occurring haplotypes were included in the association analysis of the influence of haplotype on steroid therapy outcome or IBD activity. None of the NR3C1 haplotypes showed statistically signifi cant association with glucocorticoid therapy success. CONCLUSION: NR3C1 haplotypes are not related to steroid therapy outcome. | Jessica Mwinyi Christa Wenger Jyrki J Eloranta Gerd A Kullak-Ublick | 2010 | World Journal of Gastroenterology2010，16，31： | 2 |
