1Coarctation 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 2015World Journal of Cardiology2015,7,11:27
2Coordinated peak expression of MMP-26 and TIMP-4 in preinvasive human prostate tumor显示文摘因为早察觉和治疗为病人的医药管理是批评的,为早前列腺癌症诊断的新奇简历标记的鉴定是高度重要的。在基础房间层和地下室膜的连续性的混乱为高级职业人员静电干扰 intraepithelial 瘤形成(HGPIN ) 的前进是必要的到在人的前列腺的侵略腺癌。涉及变换到侵略显型的分子是强烈审查的题目。我们以前报导了矩阵 metalloproteinase-26 (MMP-26 ) 经由地下室膜蛋白质并且由激活 MMP-9 的酶原形式的劈开支持人的前列腺癌症房间的侵略。而且,我们发现了 metalloproteinases-4 (TIMP-4 ) 的那个织物禁止者是大多数有势力 MMP-26 的内长的禁止者。这里,我们更高示威(p<0.0001 ) 在 HGPIN 和癌症的 MMP-26 和 TIMP-4 表示,与非肿瘤的 acini 相比。他们的表示层次在 HGPIN 是最高的,但是在一样的纸巾在侵略癌症(为各个的 p<0.001 ) 衰退。连续前列腺癌症织物节染色的 Immunohistochemical 建议 MMP-26 和 TIMP-4 的 colocalization。现在的学习显示 MMP-26 和 TIMP-4 可以在 HGPIN 的变换期间起一个不可分的作用到侵略癌症并且可以也为早前列腺癌症诊断用作标记。房间研究(2006 ) 16:750-758。做 i:10.1038/sj .cr.7310089;出版联机 2006 年 8 月 29 日。Seakwoo Lee Kevin K Desai Kenneth A Iczkowski Robert G Newcomer Kevin J WU Yun-Ge Zhao Winston W Tan Mark D Roycik Qing-Xiang Amy Sang 2006Cell Research2006,16,9:18
3Role of microbial dysbiosis in the pathogenesis of esophageal mucosal disease:A paradigm shift from acid to bacteria?显示文摘Genomic sequencing,bioinformatics,and initial speciation(e.g.,relative abundance)of the commensal microbiome have revolutionized the way we think about the“human”body in health and disease.The interactions between the gut bacteria and the immune system of the host play a key role in the pathogenesis of gastrointestinal diseases,including those impacting the esophagus.Although relatively stable,there are a number of factors that may disrupt the delicate balance between the luminal esophageal microbiome(EM)and the host.These changes are thought to be a product of age,diet,antibiotic and other medication use,oral hygiene,smoking,and/or expression of antibiotic products(bacteriocins)by other flora.These effects may lead to persistent dysbiosis which in turn increases the risk of local inflammation,systemic inflammation,and ultimately disease progression.Research has suggested that the etiology of gastroesophageal reflux disease-related esophagitis includes a cytokine-mediated inflammatory component and is,therefore,not merely the result of esophageal mucosal exposure to corrosives(i.e.,acid).Emerging evidence also suggests that the EM plays a major role in the pathogenesis of disease by inciting an immunogenic response which ultimately propagates the inflammatory cascade.Here,we discuss the potential role for manipulating the EM as a therapeutic option for treating the root cause of various esophageal disease rather than just providing symptomatic relief(i.e.,acid suppression).Steve M D'Souza Kevin Houston Lauren Keenan Byung Soo Yoo Parth J Parekh David A Johnson 2021World Journal of Gastroenterology2021,27,18:8
4睾酮与男性心血管疾病显示文摘尽管冠状动脉疾病(CAD)的发病存在地域差异,但相对于女性,男性的CAD发病及死亡率还是较高。性激素的性别特异性影响起着一定的作用。本文对目前睾酮在男性CAD中起的作用进行了概述,包括年龄相关的睾酮下降,睾酮水平与CAD、CAD风险因子和死亡率之间的关系。同时我们也论述了睾酮的血管活性作用,并讨论了其在心衰和心绞痛男性病人中的应用。我们还讨论了CAD男性病人的低睾酮水平是其“缘由”还是“影响”的争议,以及用睾酮补充疗法治疗中老年男性的各种顾虑。文章最后提出了此领域未来研究的方向,包括用睾酮补充疗法治疗男性CAD病人及其优缺点等。Paul D Morris Kevin S Channer 2012Asian Journal of Andrology2012,14,3:8
5Vanishing bile duct syndrome in human immunodeficiency virus infected adults:A report of two cases显示文摘Vanishing bile duct syndrome(VBDS) is a group of rare disorders characterized by ductopenia,the progressive destruction and disappearance of intrahepatic bile ducts leading to cholestasis.Described in association with medications,autoimmune disorders,cancer,transplantation,and infections,the specific mechanisms of disease are not known.To date,only 4 cases of VBDS have been reported in human immunodeficiency virus(HIV) infected patients.We report 2 additional cases of HIV-associated VBDS and review the features common to the HIV-associated cases.Presentation includes hyperbilirubinemia,normal liver imaging,and negative viral and autoimmune hepatitis studies.In HIV-infected subjects,VBDS occurred at a range of CD4+ T-cell counts,in some cases following initiation or change in antiretroviral therapy.Lymphoma was associated with two cases;nevirapine,antibiotics,and viral co-infection were suggested as etiologies in the other cases.In HIV-positive patients with progressive cholestasis,early identification of VBDS and referral for transplantation may improve outcomes.Ana Paula Oppenheimer Christopher Koh Mary McLaughlin John C Williamson Thomas D Norton Jennifer Laudadio Theo Heller David E Kleiner Kevin P High Caryn G Morse 2013World Journal of Gastroenterology2013,19,1:8
6Sequential light programs shape kale (Brassica napus) sproutappearance and alter metabolic and nutrient content显示文摘Different light wavelengths have specific effects on plant growth and development.Narrow-bandwidth light-emitting diode(LED)lighting may be used to directionally manipulate size,color and metabolites in high-value fruits and vegetables.In this report,Red Russian kale(Brassica napus)seedlings were grown under specific light conditions and analyzed for photomorphogenic responses,pigment accumulation and nutraceutical content.The results showed that this genotype responds predictably to darkness,blue and red light,with suppression of hypocotyl elongation,development of pigments and changes in specific metabolites.However,these seedlings were relatively hypersensitive to far-red light,leading to uncharacteristically short hypocotyls and high pigment accumulation,even after growth under very low fluence rates(,1 mmol m^(-2) s^(-1)).General antioxidant levels and aliphatic glucosinolates are elevated by far-red light treatments.Sequential treatments of darkness,blue light,red light and far-red light were applied throughout sprout development to alter final product quality.These results indicate that sequential treatment with narrow-bandwidth light may be used to affect key economically important traits in high-value crops.Sofia D Carvalho Kevin M Folta 2014Horticulture Research2014,1,1:6
7Role of autophagy in differential sensitivity of hepatocarcinoma cells to sorafenib显示文摘AIM: To investigate the role of sorafenib(SFN) in autophagy of hepatocellular carcinoma(HCC). We evaluated how SFN affects autophagy signaling pathway in human HCC cell lines. METHODS: Two different human HCC cell lines, Hep3 B and Huh7, were subjected to different concentrations of SFN. Cell viability and onset of apoptosis were determined with colorimetric assay and immunoblotting analysis, respectively. The changes in autophagy-related proteins, including LC3, ULK1, AMPK, and LKB, were determined with immunoblotting analysis in the presence or absence of SFN. To assess autophagic dynamics, autophagic flux was measured with chloroquine, a lysosomal inhibitor. The autophagic responsiveness between different HCC cell lines was compared under the autophagy enhancing conditions.RESULTS: Hep3 B cells were significantly more resistant to SFN than Huh7 cells. Immunoblotting analysis revealed a marked increase in SFN-mediated autophagy flux in Huh7 cells, which was, however, absent in Hep3 B cells. While both starvation and rapamycin enhanced autophagy in Huh7 cells, only rapamycin increased autophagy in Hep3 B cells. Immunoblotting analysis of autophagy initiation proteins showed that SFN substantially increased phosphorylation of AMPK and consequently autophagy in Huh7, but not in Hep3 B cells.CONCLUSION: The autophagic responsiveness to SFN is distinct between Hep3 B and Huh7 cells. Resistance of Hep3 B cells to SFN may be associated with altered autophagy signaling pathways.Trevan D Fischer Jin-Hee Wang Adrian Vlada Jae-Sung Kim Kevin E Behrns 2014World Journal of Hepatology2014,6,10:5

9Diaporthe species occurring on citrus in China显示文摘Diaporthe species are important pathogens of a wide range of hosts including many economically important crops.Diaporthe citri is generally accepted to cause melanose of Citrus fruits,leaves and shoots;stem-end rot of fruits and gummosis of perennial branches.In this study,147 strains of Diaporthe were isolated from diseased leaves,twigs,fruits and branches of Citrus from Shaanxi,Zhejiang,Guangxi,Fujian,Guangdong,Jiangxi,Hunan,Chongqing and Shanghai and identified by morphology and molecular analysis of nuclear ribosomal internal transcribed spacer(ITS),partial sequences of translation elongation factor 1-α(EF 1-α),tubulin(TUB)and calmodulin(CAL)genes.All strains from Citrus clustered in three clades.Diaporthe citri was the predominant species and is compared with strains from Florida,USA,where this species was first collected and described.Two new taxa differing from D.citri are described as D.citriasiana and D.citrichinensis in this paper.Inoculation tests indicate that all three species are able to cause stem-end rot of fruits,while only D.citri could cause melanose on leaves.Feng Huang Xin Hou Megan M Dewdney Yushi Fu Guoqing Chen Kevin D Hyde Hongye Li 2013Fungal Diversity2013,,4:4

11Pathotypes and Genetic Diversity of Chinese Collections of Elsinoě fawcettii Causing Citrus Scab显示文摘Two scab diseases are currently recognized on citrus: citrus scab, caused by El sino? fawcettii, and sweet orange scab, caused by E. australis. Although these pathogens are economically important, there is no molecular data on these species in China. Here we use internal transcribed spacer sequence data to report on host-specificity and genetic relationships among 46 isolates collected from the main citrus varieties grown across China. All strains isolated were E. fawcettii. Based on pathogenicity testing on 9 diffe rent citrus species, isolates were divided into 11 path otypes(SM, FBHR, SJCR, SPOJCR, SR, SOJG, SPOJC, SRGC, Lemon and two unnamed pathotypes). SM is a new pathotype, and two isolates did not fit into any of the known pathotypes of E. fawcettii. Inter-simple sequence repeat(ISSR-PCR) assays separated the E. fawcettii isolates into 10 subgroups; the groupings basically corresponded to the pathogenicity test.HOU Xin HUANG Feng ZHANG Tian-yuan XU Jian-guo Hyde D Kevin LI Hong-ye 2014Journal of Integrative Agriculture2014,13,6:4
12Epistaxis in end stage liver disease masquerading as severe upper gastrointestinal hemorrhage显示文摘AIM:To describe the prevalence,diagnosis,treatment,and outcomes of end stage liver disease(ESLD) patients with severe epistaxis thought to be severe upper gastrointestinal hemorrhage(UGIH).METHODS:This observational single center study included all consecutive patients with ESLD and epistaxis identified from consecutive subjects hospitalized with suspected UGIH and prospectively enrolled in our databases of severe UGIH between 1998 and 2011.RESULTS:A total of 1249 patients were registered for severe UGIH in the data basis,461(36.9%) were cirrhotics. Epistaxis rather than UGIH was the bleeding source in 20 patients. All patients had severe coagulopathy. Epistaxis was initially controlled in all cases. Fifteen(75%) subjects required posterior nasal packing and 2(10%) embolization in addition to correction of coagulopathy. Five(25%) patients died in the hospital,12(60%) received orthotopic liver transplantation(OLT),and 3(15%) were discharged without OLT. The mortality rate was 63% in patients without OLT.CONCLUSION:Severe epistaxis in patients with ESLD is(1) a diagnosis of exclusion that requires upper endoscopy to exclude severe UGIH;and(2) associated with a high mortality rate in patients not receiving OLT.Marine Camus Dennis M Jensen Jason D Matthews Gordon V Ohning Thomas O Kovacs Rome Jutabha Kevin A Ghassemi Gustavo A Machicado Gareth S Dulai 2014World Journal of Gastroenterology2014,20,38:3

15Rho A signaling and blood pressure: The consequence of failing to “Tone it Down”显示文摘Uncontrolled high blood pressure is a major risk factor for heart attack, stroke, and kidney failure and contributes to an estimated 25% of deaths worldwide. Despite numerous treatment options, estimates project that reasonable blood pressure(BP) control is achieved in only about half of hypertensive patients. Improvements in the detection and management of hypertension will undoubtedly be accomplished through a better understanding of the complex etiology of this disease and a more comprehensive inventory of the genes and genetic variants that influence BP regulation. Recent studies(primarily in pre-clinical models) indicate that the small GTPase Rho A and its downstream target, Rho kinase, play an important role in regulating BP homeostasis. Herein, we summarize the underlying mechanisms and highlight signaling pathways and regulators that impart tight spatial-temporal control of Rho A activity. We also discuss known allelic variations in the Rho A pathway and consider how these polymorphisms may affect genetic risk for hypertension and its clinical manifestations. Finally, we summarize the current(albeit limited) clinical data on the efficacy of targeting the Rho A pathway in hypertensive patients.Xue Bai Rachel Dee Kevin D Mangum Christopher P Mack Joan M Taylor 2016World Journal of Hypertension2016,6,1:3
16Using quality improvement methods to increase use of pain prevention strategies for childhood vaccination显示文摘AIM To increase evidence-based pain prevention strategy use during routine vaccinations in a pediatric primary care clinic using quality improvement methodology.METHODS Specific intervention strategies(i.e.,comfort positioning,nonnutritive sucking and sucrose analgesia,distraction) were identified,selected and introduced in three waves,using a Plan-Do-Study-Act framework.System-wide change was measured from baseline to post-intervention by:(1) percent of vaccination visits during which an evidence-based pain prevention strategy was reported as being used; and(2) caregiver satisfaction ratings following the visit.Additionally,self-reported staff and caregiver attitudes and beliefs about pain prevention were measured at baseline and 1-year post-intervention to assess for possible long-term cultural shifts.RESULTS Significant improvements were noted post-intervention.Use of at least one pain prevention strategy was documented at 99% of patient visits and 94% of caregivers were satisfied or very satisfied with the pain prevention care received.Parents/caregivers reported greater satisfaction with the specific pain prevention strategy used [t(143) = 2.50,P ≤ 0.05],as well as greater agreement that the pain prevention strategies used helped their children's pain [t(180) = 2.17,P ≤ 0.05] and that they would be willing to use the same strategy again in the future [t(179) = 3.26,P ≤ 0.001] as compared to baseline.Staff and caregivers also demonstrated a shift in attitudes from baseline to 1-year post-intervention.Specifically,staff reported greater agreement that the pain felt from vaccinations can result in harmful effects [2.47 vs 3.10; t(70) =-2.11,P ≤ 0.05],less agreement that pain from vaccinations is 'just part of the process' [3.94 vs 3.23; t(70) = 2.61,P ≤ 0.05],and less agreement that parents expect their children to experience pain during vaccinations [4.81 vs 4.38; t(69) = 2.24,P ≤ 0.05].Parents/caregivers reported more favorable attitudes about pain prevention strategies for vaccinations across a variety of areas,including safety,cost,time,and effectiveness,as well as less concern about the pain their children experience with vaccination [4.08 vs 3.26; t(557) = 6.38,P ≤ 0.001],less need for additional pain prevention strategies [3.33 vs 2.81; t(476) = 4.51,P ≤ 0.001],and greater agreement that their doctors' office currently offers pain prevention for vaccinations [3.40 vs 3.75; t(433) =-2.39,P ≤ 0.05].CONCLUSION Quality improvement methodology can be used to help close the gap in implementing pain prevention strategies during routine vaccination procedures for children.Jennifer Verrill Schurman Amanda D Deacy Rebecca J Johnson Jolynn Parker Kristi Williams Dustin Wallace Mark Connelly Lynn Anson Kevin Mroczka 2017World Journal of Clinical Pediatrics2017,6,1:3
17White matter hyperintensity progression is associated with incident probable dementia or mild cognitive impairment显示文摘Background White matter hyperintensity(WMH)on brain MRI is associated with developing dementia or mild cognitive impairment(MCI),but WMH progression over time has not been fully investigated as an independent risk factor.Methods We performed a post hoc analysis of the Systolic Blood Pressure Intervention Trial-Memory and Cognition in Decreased Hypertension(SPRINT MIND)trial.The primary outcome was incident probable dementia or MCI(dementia/MCI)before the follow-up MRI at 48 months from enrolment.The primary predictor was WMH progression,defined as the Z score difference between the follow-up and baseline WMH volumes.The secondary predictor was a binary WMH progression threshold(≥1.4 mL vs<1.4 mL).Results Among the 433 included patients,33(7.6%)developed dementia/MCI.There were 156(36.0%)patients who met the WMH progression threshold of≥1.4 mL,in whom the rate of dementia/MCI was 12.8%(20/156)vs 4.7%(13/277)of patients with<1.4 mL WMH progression(p=0.002).In multivariable logistic regression,the Z score of WMH progression was associated with dementia/MCI(OR 1.51,95%CI 1.12 to 2.04,p=0.007)as was the WMH progression threshold of≥1.4 mL(OR 2.89,95%CI 1.23 to 6.81,p=0.015).Conclusions In this post hoc analysis of SPRINT MIND,WMH progression over 48 months was associated with the development of probable dementia or MCI.Adam de Havenon Kevin N Sheth Sharon D Yeatts Tanya N Turan Shyam Prabhakaran 2022Stroke & Vascular Neurology2022,7,4:2
