| 1 | Coarctation of the aorta:Management from infancy to adulthood显示文摘Coarctation of the aorta is a relatively common form of congenital heart disease, with an estimated incidence of approximately 3 cases per 10000 births. Coarctation is a heterogeneous lesion which may present across all age ranges, with varying clinical symptoms, in isolation, or in association with other cardiac defects. The first surgical repair of aortic coarctation was described in 1944, and since that time, several other surgical techniques have been developed and modified. Additionally, transcatheter balloon angioplasty and endovascular stent placement offer less invasive approaches for the treatment of coarctation of the aorta for some patients. While overall morbidity and mortality rates are low for patients undergoing intervention for coarctation, both surgical and transcatheter interventions are not free from adverse outcomes. Therefore, patients must be followed closely over their lifetime for complications such as recoarctation, aortic aneurysm, persistent hypertension, and changes in any associated cardiac defects. Considerable effort has been expended investigating the utility and outcomes of various treatment approaches for aortic coarctation, which are heavily influenced by a patient's anatomy, size, age, and clinical course. Here we review indications for intervention, describe and compare surgical and transcatheter techniques for management of coarctation, and explore the associated outcomes in both children and adults. | Rachel D Torok Michael J Campbell Gregory A Fleming Kevin D Hill | 2015 | World Journal of Cardiology2015,7,11: | 27 |
| 2 | Passive expansion of sub-maximally dilated transjugular intrahepatic portosystemic shunts and assessment of clinical outcomes显示文摘AIM To assess for passive expansion of sub-maximally dilated transjugular intrahepatic portosystemic shunts(TIPS) and compare outcomes with maximally dilated TIPS.METHODS Polytetrafluoroethylene covered TIPS(Viatorr) from July 2002 to December 2013 were retrospectively reviewed at two hospitals in a single institution. Two hundred and thirty patients had TIPS maximally dilated to 10 mm(m TIPS), while 43 patients who were at increased risk for hepatic encephalopathy(HE), based on clinical evaluation or low pre-TIPS portosystemic gradient(PSG), had 10 mm TIPS sub-maximally dilated to 8 mm(sm TIPS). Group characteristics(age, gender, Model for End-Stage Liver Disease score, post-TIPS PSG and clinical outcomes were compared between groups, including clinical success(ascites or varices), primary patency,primary assisted patency, and severe post-TIPS HE. A subset of fourteen patients with sm TIPS underwent follow-up computed tomography imaging after TIPS creation, and were grouped based on time of imaging(< 6 mo and > 6 mo). Change in diameter and crosssectional area were measured with 3D imaging software to evaluate for passive expansion.RESULTS Patient characteristics were similar between the sm TIPS and m TIPS groups, except for pre-TIPS portosystemic gradient, which was lower in the sm TIPS group(19.4 mm Hg ± 6.8 vs 22.4 mm Hg ± 7.1, P = 0.01). Primary patency and primary assisted patency between sm TIPS and m TIPS was not significantly different(P = 0.64 and 0.55, respectively). Four of the 55 patients(7%) with sm TIPS required TIPS reduction for severe refractory HE, while this occurred in 6 of the 218 patients(3%) with m TIPS(P = 0.12). For the 14 patients with follow-up computed tomography(CT) imaging, the median imaging follow-up was 373 d. There was an increase in median TIPS diameter, median percent diameter change, median area, and median percent area change in patients with CT follow-up greater than 6 mo after TIPS placement compared to follow-up within 6 mo(8.45 mm, 5.58%, 56.04 mm^2, and 11.48%, respectively, P = 0.01).CONCLUSION Passive expansion of sm TIPS does occur but clinical outcomes of sm TIPS and m TIPS were similar. Sub-maximal dilation can prevent complications related to overshunting in select patients. | Michael C Hsu Charles N Weber S William Stavropoulos Timothy W Clark Scott O Trerotola Richard D Shlansky Goldberg Michael C Soulen Gregory J Nadolski | 2017 | World Journal of Hepatology2017,9,12: | 11 |
| 3 | Metformin does not improve survival in patients with hepatocellular carcinoma显示文摘AIM:To assess whether metformin,which has a chemopreventive effect in chronic liver disease,has any chemotherapeutic effect in hepatocellular carcinoma.METHODS:This was a retrospective study of 701 patients with newly diagnosed hepatocellular carcinoma(HCC)seen between January 2005 and June 2011 at Mayo Clinic,Rochester,Minnesota.This patient cohort was a part of the global HCC BRIDGE study,which is a large longitudinal study of HCC determining the realworld experience of HCC characteristics,management and patient outcomes.We defined significant metformin exposure as continuation of this agent at least 90d beyond diagnosis of HCC,and compared survival of diabetic patients on metformin to diabetic patients not on metformin and non-diabetics.RESULTS:Our cohort was 72.9%male,with a mean±SD age of 62.6±12.3 years.The most common etiologies of liver disease were hepatitis C(34%),alcoholic liver disease(29%),fatty liver disease(15%)and hepatitis B(9%).By univariate analysis,using diabetics not on metformin as the reference group,diabetic patients with HCC on metformin had no survival advantage,with a HR(95%CI)of 1.0(0.8-1.3).Non-diabetic HCC patients also did not appear to have a survival advantage as compared to diabetic HCC patients not on metformin,as demonstrated by a HR(95%CI)of1.1(0.7-1.7).Diabetics on metformin beyond 90 d after HCC diagnosis had a longer median survival at 34.2 mo,as compared to 25.5 mo among diabetic patients who were not on metformin or had discontinued metformin within 90 d after HCC diagnosis.This finding was likely due to potential survival bias among those who lived long enough to receive metformin.CONCLUSION:Although the literature suggests a chemotherapeutic effect in other malignancies,our study demonstrates no survival benefit to the use of metformin in diabetic patients with HCC. | Mamatha Bhat Roongruedee Chaiteerakij William S Harmsen Cathy D Schleck Ju Dong Yang Nasra H Giama Terry M Therneau Gregory J Gores Lewis R Roberts | 2014 | World Journal of Gastroenterology2014,20,42: | 11 |
| 4 | Transradial versus transfemoral access for anterior circulation mechanical thrombectomy: analysis of 375 consecutive cases显示文摘Objective To compare transradial artery access(TRA)to the gold standard of transfemoral artery access(TFA)in mechanical thrombectomy(MT)for stroke caused by anterior circulation large vessel occlusion.Methods The clinical outcomes,procedural speed,angiographic efficacy and safety of both techniques were analysed in 375 consecutive cases over an 18-month period in a high volume statewide neurointerventional service.Results There was no significant difference in patient characteristics,stroke parameters,imaging techniques or intracranial techniques.The median time elapsed between CT scanning and reperfusion was 96.5 min(IQR 68-123)in the TFA group and 95 min(IQR 68-123)in the TRA group(p=0.456).Of 336 patients who were independent at presentation 58%(124/214)of the TFA group and 67%(82/122)of the TRA group had a modified Rankin score of 0-2 at 90-day follow-up(p=0.093).Cross-over from radial to femoral was 4.6%(4/130)compared with 1.6%cross-over from femoral to radial(4/245),but did not meet the predetermined level of statistical significance(OR2.92,95% CI 0.81 to 10.52,p=0.088) and did not impact median procedural speed.Adequate angiographic reperfusion,first pass reperfusion,embolisation to new territory and symptomatic intracranial haemorrhage were similar in both groups.There was a significant difference in major access site complications requiring an additional procedure.None of the TRA cases had a major access site complication but 6.5%(16/245)of the TFA cases did(p=0.003).Conclusion This study suggests that using TRA for anterior circulation MT is fast,efficacious,safe and not inferior to the gold standard of TFA. | Timothy John Phillips Matthew Thomas Crockett Gregory D Selkirk Ruchi Kabra Albert Ho Yuen Chiu Tejinder Singh Constantine Phatouros William McAuliffe | 2021 | Stroke & Vascular Neurology2021,6,2: | 7 |

| 6 | Management of stage Ⅳ rectal cancer: Palliative options显示文摘Approximately 30% of patients with rectal cancer present with metastatic disease. Many of these patients have symptoms of bleeding or obstruction. Several treatment options are available to deal with the various complications that may afflict these patients. Endorectal stenting, laser ablation, and operative resection are a few of the options available to the patient with a malignant large bowel obstruction. A thorough understanding of treatment options will ensure the patient is offered the most effective therapy with the least amount of associated morbidity. In this review, we describe various options for palliation of symptoms in patients with metastatic rectal cancer. Additionally, we briefly discuss treatment for asymptomatic patients with metastatic disease. | Sean M Ronnekleiv-Kelly Gregory D Kennedy | 2011 | World Journal of Gastroenterology2011,17,7: | 5 |

| 8 | 腔内介入治疗血管性勃起功能障碍显示文摘过去一个世纪里,勃起功能障碍(ED)的治疗一直是一件引人关注的事情,涉及到泌尿、心血管以及手术领域的多个学科。随着ED与心血管疾病的相关性被充分证实,血管造影技术已被用来鉴别血管性阳痿。由于腔内血管药物洗脱支架植入术在治疗冠状动脉疾病获得成功,采用该技术来治疗血管性ED已激起了医务人员的浓厚兴趣。最近报道了针对阴茎流入血管狭窄的男性,植入药物洗脱支架绕过病变处动脉已获得了较高的成功率。同样,血管内栓塞治疗静脉闭塞功能障碍也取得了惊人的手术成功率。然而,查阅文献发现动脉介入只推荐应用于治疗年轻的孤立性血管损伤的患者,通常为那些先前经历过创伤的患者。该手术的短期功能恢复没有达到最佳,长期疗效也有待进一步观察。总之,用微创方法治疗勃起功能障碍的希望仍然存在,但是在获得普遍认可之前仍需要进一步的研究。 | Edward D Kim Ryan C Owen Gregory S White Osama O Elkelany Cyrus D Rahnema | 2015 | Asian Journal of Andrology2015,17,1: | 3 |
| 9 | Paramyxovirus evasion of innate immunity: Diverse strategies for common targets显示文摘The paramyxoviruses are a family of > 30 viruses that variously infect humans, other mammals and fish to cause diverse outcomes, ranging from asymptomatic to lethal disease, with the zoonotic paramyxoviruses Nipah and Hendra showing up to 70% case-fatality rate in humans. The capacity to evade host immunity is central to viral infection, and paramyxoviruses have evolved multiple strategies to overcome the host interferon(IFN)-mediated innate immune response through the activity of their IFN-antagonist proteins. Although paramyxovirus IFN antagonists generally target common factors of the IFN system, including melanoma differentiation associated factor 5, retinoic acid-inducible gene-I, signal transducers and activators of transcription(STAT)1 and STAT2, and IFN regulatory factor 3, the mechanisms of antagonism show remarkable diversity between different genera and even individual members of the same genus; the reasons for this diversity, however, are not currently understood. Here, we review the IFN antagonism strategies of paramyxoviruses, highlighting mechanistic differences observed between individual species and genera. We also discuss potential sources of this diversity, including biological differences in the host and/or tissue specificity of different paramyxoviruses, and potential effects of experimental approaches that have largely relied on in vitrosystems. Importantly, recent studies using recombinant virus systems and animal infection models are beginning to clarify the importance of certain mechanisms of IFN antagonism to in vivo infections, providing important indications not only of their critical importance to virulence, but also of their potential targeting for new therapeutic/vaccine approaches. | Michelle D Audsley Gregory W Moseley | 2013 | World Journal of Virology2013,2,2: | 2 |
| 10 | Outcomes after arthroscopic repair of rotator cuff tears in the setting of mild to moderate glenohumeral osteoarthritis显示文摘BACKGROUND Rotator cuff pathology is a very common source of shoulder pain.Similarly,osteoarthritis of the glenohumeral joint can cause shoulder pain and produce similar symptoms.Surgical management can be indicated for both pathologies,however,outcomes data is limited when examining rotator cuff repair(RCR) in the setting of glenohumeral arthritis(GHOA).Thus,this study sought to determine outcomes for patients who undergo RCR in the setting of GHOA.AIM To evaluate if a relationship exists between outcomes of RCR in the setting of GHOA.METHODS This was a retrospective analysis of patients who underwent arthroscopic rotator cuff repair with concurrent glenohumeral osteoarthritis between 2010-2017.Patients were stratified based on rotator cuff tear size and glenohumeral osteoarthritis severity.Cohorts were paired 1:1 with patients without glenohumeral osteoarthritis.Patients included had a minimum two year follow-up.Rate of conversion to total shoulder arthroplasty,complication rates following initial surgery,and patient-reported outcome measures were collected.RESULTS A total of 142 patients were included.The number of patients that required total shoulder arthroplasty within two years after index surgery was low.2/71(2.8%) patients with GHOA,and 1/71(1.4%) without GHOA.Following rotator cuff repair,both groups showed favorable patientreported outcomes.CONCLUSION Patients with glenohumeral osteoarthritis who underwent arthroscopic rotator cuff repair showed comparable outcomes to patients without glenohumeral osteoarthritis. | Ian S Hong Allison J Rao Tyler L CarlLee Joshua D Meade Daniel J Hurwit Gregory Scarola David P Trofa Shadley C Schiffern Nady Hamid Patrick M Connor James E Fleischli Bryan Michael Saltzman | 2022 | World Journal of Orthopedics2022,13,7: | 2 |

| 13 | Serotonin type 3 receptor subunit gene polymorphisms associated with psychosomatic symptoms in irritable bowel syndrome:A multicenter retrospective study显示文摘BACKGROUND Single-nucleotide polymorphisms(SNPs)of the serotonin type 3 receptor subunit(HTR3)genes have been associated with psychosomatic symptoms,but it is not clear whether these associations exist in irritable bowel syndrome(IBS).AIM To assess the association of HTR3 polymorphisms with depressive,anxiety,and somatization symptoms in individuals with IBS.METHODS In this retrospective study,623 participants with IBS were recruited from five specialty centers in Germany,Sweden,the United States,the United Kingdom,and Ireland.Depressive,anxiety,and somatization symptoms and sociodemographic characteristics were collected.Four functional SNPs—HTR3A c.-42C>T,HTR3B c.386A>C,HTR3C c.489C>A,and HTR3E c.*76G>A—were genotyped and analyzed using the dominant and recessive models.We also performed separate analyses for sex and IBS subtypes.SNP scores were calculated as the number of minor alleles of the SNPs above.The impact of HTR3C c.489C>A was tested by radioligand-binding and calcium influx assays.RESULTS Depressive and anxiety symptoms significantly worsened with increasing numbers of minor HTR3C c.489C>A alleles in the dominant model(F_(depressive)=7.475,P_(depressive)=0.006;F_(anxiety)=6.535,P_(anxiety)=0.011).A higher SNP score(range 0-6)was linked to a worsened depressive symptoms score(F=7.710,P-linear trend=0.006)in IBS.The potential relevance of the HTR3C SNP was corroborated,showing changes in the expression level of 5-HT3AC variant receptors.CONCLUSION We have provided the first evidence that HTR3C c.489C>A is involved in depressive and anxiety symptoms in individuals with IBS.The SNP score indicated that an increasing number of minor alleles is linked to the worsening of depressive symptoms in IBS. | Sabrina Berens Yuanjun Dong Nikola Fritz Jutta Walstab Mauro D'Amato Tenghao Zheng Verena Wahl Felix Boekstegers Justo Lorenzo Bermejo Cristina Martinez Stefanie Schmitteckert Egbert Clevers Felicitas Engel Annika Gauss Wolfgang Herzog Robin Spiller Miriam Goebel-Stengel Hubert Mönnikes Viola Andresen Frieling Thomas Jutta Keller Christian Pehl Christoph Stein-Thöringer Gerard Clarke Timothy G Dinan Eamonn M Quigley Gregory Sayuk Magnus Simrén Jonas Tesarz Gudrun Rappold Lukas van Oudenhove Rainer Schaefert Beate Niesler | 2022 | World Journal of Gastroenterology2022,28,21: | 2 |
