1美国国立老化研究所与阿尔茨海默病协会诊断指南写作组:阿尔茨海默病痴呆诊断标准的推荐显示文摘由美国国立老化研究所(NIA)和阿尔茨海默病(AD)协会组织了一个工作组,负责修订1984年版AD痴呆的诊断标准。旨在确保修订后的标准具有足够的灵活性,既可供缺乏神经心理学测验、先进的影像技术和脑脊液检查措施的普通医务人员使用,也可供具备上述措施的科研、临床试验的专业研究者使用。新的标准广泛适用于各种原因的痴呆以及专门针对AD痴呆的标准,保留了1984年版标准中的“很可能的AD痴呆”的总体框架。在过去27年的经验基础上,工作组对临床诊断标准做了一些修改,保留了“可能的AD痴呆”的术语,但对其进行了更有针对性的重新定义。在科研用的“很可能的和可能的AD痴呆”的诊断标准中纳入了生物标志物证据。AD痴呆的核心临床标准仍将是临床实践中诊断的基础,但用生物标志物证据来提高AD痴呆诊断的病理生理学特异性也被人们寄予厚望。要实现AD痴呆的生物标志物诊断,还有许多工作摆在面前。McKhann GM Knopman DS Chertkow H Hyman BT Jack CR Jr Kawas CH Klunk WE Koroshetz WJ Manly J J Mayeux R Mohs RC Morris JC Rossor MN Scheltens P Carrillo MC Thies B Weintraub S Phelps CH 贾建平(译) 陆璐(译) 张逸驰(译) 黄丽(译) 韩阅(译) 2012中华神经科杂志2012,45,5:52
2Radiofrequency ablation for early oesophageal squamous neoplasia:Outcomes form United Kingdom registry显示文摘AIM:To report outcomes on patients undergoing radiofrequency ablation(RFA)for early oesophageal squamous neoplasia from a National Registry.METHODS:A Prospective cohort study from 8 tertiary referral centres in the United Kingdom.Patients with squamous high grade dysplasia(HGD)and early squamous cell carcinoma(ESCC)confined to the mucosa were treated.Visible lesions were removed by endoscopic mucosal resection(EMR)before RFA.Following initial RFA treatment,patients were followed up 3monthly.Residual flat dysplasia was treated with RFA until complete reversal dysplasia(CR-D)was achieved or progression to invasive Squamous cell cancer defined as infiltration into the submucosa layer or beyond.The main outcome measures were CR-D at 12 mo from start of treatment,long term durability,progression to cancer and adverse events.RESULTS:Twenty patients with squamous HGD/ESCC completed treatment protocol.Five patients(25%)had EMR before starting RFA treatment.CR-D was 50%at12 mo with a median of 1 RFA treatment,mean 1.5(range 1-3).Two further patients achieved CR-D with repeat RFA after this time.Eighty per cent with CR-D remain dysplasia free at latest biopsy,with median follow up 24 mo(IQR 17-54).Six of 20 patients(30%)progressed to invasive cancer at 1 year.Four patients(20%)required endoscopic dilatations for symptomatic structuring after treatment.Two of these patients have required serial dilatations thereafter for symptomatic dysphagia with a median of 4 dilatations per patient.The other 2 patients required only a single dilatation to achieve an adequate symptomatic response.One patient developed cancer during follow up after end of treatment protocol.CONCLUSION:The role of RFA in these patients re-mains unclear.In our series 50%patients responded at12 mo.These figures are lower than limited published data.Rehan J Haidry Mohammed A Butt Jason Dunn Matthew Banks Abhinav Gupta Howard Smart Pradeep Bhandari Lesley Ann Smith Robert Willert Grant Fullarton Morris John Massimo Di Pietro Ian Penman Marco Novelli Laurence B Lovat 2013World Journal of Gastroenterology2013,19,36:7
3创伤性脑损伤后蛛网膜下腔出血与长期卒中风险的关系(英文)显示文摘BACKGROUND Recent studies suggest that traumatic brain injury(TBI)is a risk factor for subsequent ischemic stroke,even years after the initial insult.The mechanisms of the association remain unclear.The presence of traumatic subarachnoid hemorrhage(t SAH)may mediate the effect of TBI on long-term stroke risk,as it has previously been linked to short-term vasospasm and delayed cerebral ischemia.METHODS Using administrative claims data,we conducted a retrospective cohort study of acute care hospitalizations.Patients discharged with a first-recorded diagnosis of t SAH were followed for a primary diagnosis of stroke.They were matched to patients with TBI but not t SAH.Cox proportional hazards modeling was used to assess the association between t SAH and stroke while adjusting for covariates.RESULTS:We identified 40 908 patients with TBI(20 454 patients with t SAH)who were followed for a mean of 4.3+1.8 years.A total of 531 had an ischemic stroke after discharge.There was no significant difference in stroke risk between those with t SAH(1.79%;95%confidence interval[CI]1.54%-2.08%)versus without t SAH(2.12%;95%CI 1.83%-2.44%).The same pattern was found in adjusted analyses even when the group was stratified by age-group or by proxies of TBI severity.CONCLU-SIONS:Our findings do not support a role of t SAH in mediating the association between TBI and protracted stroke risk.Further study is required to elucidate the mechanisms of long-term increased stroke risk after TBI.Morris NA Cool J Merkler AE Kamel H 2017中华神经外科疾病研究杂志2017,16,4:6
4骨吸收抑制剂对老年短尾猴椎体松质骨微损伤和骨重建的影响显示文摘目的 评估骨吸收抑制剂对骨微损伤和骨重建的影响.方法将20只雌性短尾猴(18~22岁)按体重随机分为5组:对照组(CNT,n=4),低剂量依降钙素组[0.5 U/(kg·d),ELL,n=4],高剂量依降钙素组[5 U/(kg·d),ELH,n=4],低剂量阿仑膦酸盐组[10 μg/(kg·d),ALL,n=4]和高剂量阿仑膦酸盐组[100 μg(kg·d),ALH,n=4].所有动物均皮下注射给药,每周2次,持续给药29周.处死前给予钙黄绿素双标,处死后取胸椎第2椎体进行松质骨微损伤测量及骨重建指标检测.结果 微损伤测量结果表明2个阿仑膦酸盐组椎体的微损伤总裂缝长度(crack length)、裂缝总数量(crack number)、骨表面密度(surface density)及裂缝密度(crack density)均较对照组和依降钙素组明显增加(P<0.01),但微损伤平均长度(mean crack length)较对照组和依降钙素组明显降低(P<0.05).高剂量降钙素组骨表面密度较对照组明显增高(P<0.01),其余各指标间差异均无统计学意义.骨重建检测结果表明阿仑膦酸盐组椎骨单标表面(sLS)、类骨质表面/骨表面(OS/BS)、类骨质厚度(O.Th)及单标表面/骨表面(sLS/BS)均较对照组明显降低(P<0.05);高剂量阿仑膦酸盐组矿化表面/类骨质表面(MS/OS)和标记表面/类骨质表面(LS/OS)较对照组明显减低(P<0.05).高剂量依降钙素组矿化表面/类骨质表面(OS/BS)和类骨质厚度(O.Th)较对照组明显降低(P<0.05),依降钙素组其余指标差异均无统计学意义.结论 依降钙素可轻微抑制老年短尾猴椎体松质骨的骨重建,但未引起骨微损伤的聚积;阿仑膦酸盐可显著抑制该猴椎体松质骨的骨重建,以及引起微损伤的聚积,但微损伤的平均长度明显降低.王瑞 曹永平 刘恒 杨昕 孟志超 吴浩 王京 Mashiba T Morri J 2013中华骨质疏松和骨矿盐疾病杂志2013,6,4:4

6Radial artery access site complications during cardiac procedures,clinical implications and potential solutions: The role of nitric oxide显示文摘Percutaneous coronary intervention for the treatment of coronary artery disease is most commonly performed in the UK through the radial artery,as this is considered to be safer than the femoral approach.However,despite improvements in technology and techniques,complications can occur.The most common complication,arterial spasm,can cause intense pain and,in some cases,procedural failure.The incidence of spasm is dependent on several variables,including operator experience,artery size,and equipment used.An antispasmolytic cocktail can be applied to reduce spasm,which usually includes an exogenous nitric oxide(NO)donor(glyceryl trinitrate).NO is an endogenous local vasodilator and therefore is a potential target for anti-spasm intervention.However,systemic administration can result in unwanted side-effects,such as hypotension.A method that adopts local delivery of NO might be advantageous.This review article describes the mechanisms involved in radial artery spasm,discusses the advantages and disadvantages of current strategies to reduce spasm,and highlight the potential of NO-loaded nanoporous materials for use in this setting.Emma M Coghill Timothy Johnson Russell E Morris Ian L Megson Stephen J Leslie 2020World Journal of Cardiology2020,12,1:4
7Upper gastrointestinal bleeding in Scotland 2000-2010: Improved outcomes but a significant weekend effect显示文摘AIM: To assess numbers and case fatality of patients with upper gastrointestinal bleeding(UGIB),effects of deprivation and whether weekend presentation affected outcomes.METHODS: Data was obtained from Information Services Division(ISD) Scotland and National Records of Scotland(NRS) death records for a ten year period between 2000-2001 and 2009-2010. We obtained data from the ISD Scottish Morbidity Records(SMR01) database which holds data on inpatient and daycase hospital discharges from non-obstetric and nonpsychiatric hospitals in Scotland. The mortality data was obtained from NRS and linked with the ISD SMR01 database to obtain 30-d case fatality. We used 23 ICD-10(International Classification of diseases) codes which identify UGIB to interrogate database. We analysed these data for trends in number of hospital admissions with UGIB,30-d mortality over time and assessed effects of social deprivation. We compared weekend and weekday admissions for differences in 30-d mortality and length of hospital stay. We determined comorbidities for each admission to establish if comorbidities contributed to patient outcome. RESULTS: A total of 60643 Scottish residents were admitted with UGIH during January,2000 and October,2009. There was no significant change in annual number of admissions over time,but there was a statistically significant reduction in 30-d case fatality from 10.3% to 8.8%(P < 0.001) over these 10 years. Number of admissions with UGIB was higher for the patients from most deprived category(P < 0.05),although case fatality was higher for the patients from the least deprived category(P < 0.05). There was no statistically significant change in this trend between 2000/01-2009/10. Patients admitted with UGIB at weekends had higher 30-d case fatality compared with those admitted on weekdays(P < 0.001). Thirty day mortality remained significantly higher for patients admitted with UGIB at weekends after adjusting for comorbidities. Length of hospital stay was also higher overall for patients admitted at the weekend when compared to weekdays,although only reached statistical significance for the last year of study 2009/10(P < 0.0005). CONCLUSION: Despite reduction in mortality for UGIB in Scotland during 2000-2010,weekend admissions show a consistently higher mortality and greater lengths of stay compared with weekdays.Asma Ahmed Matthew Armstrong Ishbel Robertson Allan John Morris Oliver Blatchford Adrian J Stanley 2015World Journal of Gastroenterology2015,21,38:4

10少量无机硝酸盐或甜菜根可有效抑制盐诱发的血压升高显示文摘为降低盐诱发高血压的风险,医学专家强调的膳食指南是促进高钾低钠摄入以使钾钠摩尔比≥1∶1。然而过去几十年间,几乎没人改变他们的膳食习惯以充分满足推荐的膳食钠钾目标。因此,降低盐诱发高血压的风险又不要求改变主要膳食习惯的新策略具有相当大的医学意义。该研究在一个广泛应用的盐诱发高血压模型Dahl盐敏感性大鼠中,发现补充硝酸盐与钠的摩尔比约为1∶170时,补充膳食硝酸盐摄入可以抑制盐诱发高血压的形成。赵狄 练桂丽 Morris RC Jr Pravenec M ■ J DiCarlo SE Kurtz TW 2019中华高血压杂志2019,27,6:3
11Variable change in renal function by hypertonic saline显示文摘AIM: To investigate the effects of hypertonic saline in the neurocritical care population.METHODS: We retrospectively reviewed our hospital's use of hypertonic saline(HS) since March of 2005, and prospectively since October 2010. Comparisons were made between admission diagnoses, creatinine change(Cr), and HS formulation(3% Na Cl, 3% Na Cl/sodium acetate mix, and 23.4% Na Cl) to patients receiving normal saline or lactated ringers. The patients(n = 1329) of the retrospective portion were identified. The data presented represents the first 230 patients with data. RESULTS: Significant differences in Acute Physiology and Chronic Health Evaluation Ⅱ scores and GlasgowComa Scale scores occurred between different saline formulations. No significant correlation of Cl- or Na+ with Cr, nor with saline types, occurred. When dichotomized by diagnosis, significant correlations appear. Traumatic brain injury(TBI) patients demonstrated moderate correlation between Na+ and Cr of 0.45. Stroke patients demonstrated weak correlations between Na+ and Cr, and Cl- and Cr(0.19 for both). Patients receiving HS and not diagnosed with intracerebral hemorrhage, stroke, subarachnoid hemorrhage, or TBI demonstrated a weak but significant correlation between Cl- and Cr at 0.29.CONCLUSION: Cr directly correlates with Na+ or Cl- in stroke, Na+ in TBI, and Cl- in other populations. Prospective comparison of HS and renal function is needed.Jesse J Corry Panayiotis Varelas Tamer Abdelhak Stacey Morris Marlisa Hawley Allison Hawkins Michelle Jankowski 2014World Journal of Critical Care Medicine2014,3,2:3
12Diagnostic accuracy of tests for Helicobacter pylori in an Alaska Native population显示文摘AIM:To evaluate the accuracy of two non-invasivetests in a population of Alaska Native persons. Highrates of Helico bacter pylori(H. pylori) infection,H. pylori treatment failure,and gastric cancer in this population necessitate documentation of infection status atmultiple time points over a patient's life.METHODS:In 280 patients undergoing endoscopy,H. pylori was diagnosed by culture,histology,rapidurease test,13C urea breath test(UBT) ,and immuno-globulin G antibodies to H. pylori in serum. The performances of 13C-UBT and antibody test were compared to a gold standard defined by a positive H. pylori testby culture or,in case of a negative culture result,bypositive histology and a positive rapid urease test.RESULTS:The sensitivity and specificity of the 13C-UBT were 93% and 88%,respectively,relative to thegold standard. The antibody test had an equivalents ensitivity of 93% with a reduced specificity of 68%.The false positive results for the antibody test were as-sociated with previous treatment for an H. pylori infection [relative risk(RR) = 2.8]. High levels of antibodiesto H. pylori were associated with chronic gastritis and male gender,while high scores in the 13C-UBT testwere associated with older age and with the H. pyloribacteria load on histological examination(RR = 4.4) .CONCLUSION:The 13C-UBT out performed the anti-body test for H. pylori and could be used when a non-invasive test is clinically necessary to document treatment out come or when monitoring for reinfection.Dana L Bruden Michael G Bruce Karen M Miernyk Julie Morris Debby Hurlburt Thomas W Hennessy Helen Peters Frank Sacco Alan J Parkinson Brian J McMahon 2011World Journal of Gastroenterology2011,17,42:3
13Regulation of Wnt/β-catenin signaling by herpesviruses显示文摘The Wnt/β-catenin signaling pathway is instrumental in successful differentiation and proliferation of mammalian cells. It is therefore not surprising that the herpesvirus family has developed mechanisms to interact with and manipulate this pathway. Successful coexistence with the host requires that herpesviruses establish a lifelong infection that includes periods of latency and reactivation or persistence. Many herpesviruses establish latency in progenitor cells and viral reactivation is linked to host-cell proliferation and differentiation status. Importantly, Wnt/β-catenin is tightly connected to stem/progenitor cell maintenance and differentiation. Numerous studies have linked Wnt/β-catenin signaling to a variety of cancers, emphasizing the importance of Wnt/β-catenin pathways in development, tissue homeostasis and disease. This review details how the alpha-, beta-, and gammaherpesviruses interact and manipulate the Wnt/β-catenin pathway to promote a virus-centric agenda.Kevin J Zwezdaryk Joseph A Combs Cindy A Morris Deborah E Sullivan 2016World Journal of Virology2016,5,4:2
14Early infant male circumcision:Systematic review,risk-benefit analysis,and progress in policy显示文摘AIM To determine whether recent evidence-based United States polices on male circumcision(MC) apply to comparable Anglophone countries,Australia and New Zealand.METHODS Articles in 2005 through 2015 were retrieved from PubM ed using the keyword 'circumcision' together with 36 relevant subtopics.A further PubM ed search was performed for articles published in 2016.Searches of the EMBASE and Cochrane databases did not yield additional citable articles.Articles were assessed for quality and those rated 2+ and above according to the Scottish Intercollegiate Grading System were studied further.The most relevant andrepresentative of the topic were included.Bibliographies were examined to retrieve further key references.Randomized controlled trials,recent high quality systematic reviews or meta-analyses(level 1++ or 1+ evidence) were prioritized for inclusion.A risk-benefit analysis of articles rated for quality was performed.For efficiency and reliability,recent randomized controlled trials,metaanalyses,high quality systematic reviews and large welldesigned studies were used if available.Internet searches were conducted for other relevant information,including policies and Australian data on claims under Medicare for MC.RESULTS Evidence-based policy statements by the American Academy of Pediatrics(AAP) and the Centers for Disease Control and Prevention(CDC) support infant and later age male circumcision(MC) as a desirable public health measure.Our systematic review of relevant literature over the past decade yielded 140 journal articles that met our inclusion criteria.Together,these showed that early infant MC confers immediate and lifelong benefits by protecting against urinary tract infections having potential adverse long-term renal effects,phimosis that causes difficult and painful erections and 'ballooning' during urination,inflammatory skin conditions,inferior penile hygiene,candidiasis,various sexually transmissible infections in both sexes,genital ulcers,and penile,prostate and cervical cancer.Our risk-benefit analysis showed that benefits exceeded procedural risks,which are predominantly minor,by up to 200 to 1.We estimated that more than 1 in 2 uncircumcised males will experience an adverse foreskin-related medical condition over their lifetime.Wide-ranging evidence from surveys,physiological measurements,and the anatomical location of penile sensory receptors responsible for sexual sensation strongly and consistently suggested that MC has no detrimental effect on sexual function,sensitivity or pleasure.United States studies showed that early infant MC is cost saving.The evidence supporting early infant MC has further strengthened since the positive AAP and CDC reviews.CONCLUSION Affirmative MC policies are needed in Australia and New Zealand.Routine provision of accurate,unbiased education,and access in public hospitals,will maximize health and financial benefits.Brian J Morris Sean E Kennedy Alex D Wodak Adrian Mindel David Golovsky Leslie Schrieber Eugenie R Lumbers David J Handelsman John B Ziegler 2017World Journal of Clinical Pediatrics2017,6,1:2

17Critical evaluation of unscientific arguments disparaging affirmative infant male circumcision policy显示文摘We evaluate recent claims opposing infant male circumcision,a procedure now supported by the evidencebased policy of the American Academy of Pediatrics.We find those criticisms depend on speculative claims about the foreskin and obfuscation of the strong scientific evidence supporting pediatric policy development.An argument that circumcision should be delayed to allow a boy to make up his own mind as an adult fails to appreciate the psychological,scheduling and financial burdens later circumcision entails,so reducing the likelihood that it will occur.In contrast,early infant circumcision is convenient,safer,quicker,lower risk,healing is faster,cosmetic outcome is routinely good and the lifetime benefits accrue immediately.Benefits include reduction in urinary tract infections,inflammatory skin conditions,foreskin problems,and,when older,substantial protection against sexually transmitted infections and genital cancers in the male and his female sexual partners.Some authorities regard the failure to offer parents early infant circumcision as unethical,just as it would be unethical to fail to encourage the vaccination of children.In conclusion,the criticisms of evidence-based infant male circumcision policy are seriously flawed and should be dismissed as unhelpful to evidence-based development and implementation of pediatric policy intended to improve public health and individual wellbeing.Brian J Morris John N Krieger Jeffrey D Klausner 2016World Journal of Clinical Pediatrics2016,5,3:2

19Mechanisms behind early life nutrition and adult disease outcome显示文摘Obesity is increasing around the globe. While adult lifestyle factors undoubtedly contribute to the incidence of obesity and its attendant disorders, mounting evidence suggests that programming of obesity may occur following underand over-nutrition during development. As hypothalamic control of appetite and energy expenditure is set early in life and can be perturbed by certain exposures such as under nutrition and altered metabolic and hormonal signals, in utero exposure to altered maternal nutrition and inadequate nutrition during early postnatal life may contribute to programming of obesity in offspring. Data from animal studies indicate both intrauterine and postnatal environments are critical determinants of the development of pathways regulating energy homeostasis. This review summarizes recent evidence of the impact of maternal nutrition as well as postnatal nutrition of the offspring on subsequent obesity and disease risk of the offspring. While much of the experimental work reviewed here was conducted in the rodent, these observations provide useful insights into avenues for future research into developing preventive measures to curb the obesity epidemic.Elena Velkoska Margaret J Morris 2011World Journal of Diabetes2011,2,8:2
