1Complications of hip fractures: A review显示文摘Nowadays, fracture surgery represents a big part of the orthopedic surgeon workload, and usually has associated major clinical and social cost implications. These fractures have several complications. Some of these are medical, and other related to the surgical treatment itself. Medical complications may affect around 20% of patients with hip fracture. Cognitive and neurological alterations, cardiopulmonary affections(alone or combined), venous thromboembolism, gastrointestinal tract bleeding, urinary tract complications, perioperative anemia, electrolytic and metabolic disorders, and pressure scars are the most important medical complications after hip surgery in terms of frequency, increase of length of stay and perioperative mortality. Complications arising from hip fracture surgery are fairly common, and vary depending on whether the fracture is intracapsular or extracapsular. The main problems in intracapsular fractures are biological: vascularization of the femoral head, and lack of periosteum-a major contributor to fracture healing- in the femoral neck. In extracapsularfractures, by contrast, the problem is mechanical, and relates to load-bearing. Early surgical fixation, the role of anti-thromboembolic and anti-infective prophylaxis, good pain control at the perioperative, detection and management of delirium, correct urinary tract management, avoidance of malnutrition, vitamin D supplementation, osteoporosis treatment and advancement of early mobilization to improve functional recovery and falls prevention are basic recommendations for an optimal maintenance of hip fractured patients.Pedro Carpintero Jose Ramón Caeiro Rocío Carpintero Angela Morales Samuel Silva Manuel Mesa 2014World Journal of Orthopedics2014,5,4:31
2Physical exercise in the prevention and treatment of Alzheimer’s disease显示文摘Dementia is one of the greatest global challenges for health and social care in the 21st century.Alzheimer’s disease(AD),the most common type of dementia,is by no means an inevitable consequence of growing old.Several lifestyle factors may increase,or reduce,an individual’s risk of developing AD.Much has been written over the ages about the benefits of exercise and physical activity.Among the risk factors associated with AD is a low level of physical activity.The relationship between physical and mental health was established several years ago.In this review,we discuss the role of exercise(aerobic and resistance)training as a therapeutic strategy for the treatment and prevention of AD.Older adults who exercise are more likely to maintain cognition.We address the main protective mechanism on brain function modulated by physical exercise by examining both human and animal studies.We will pay especial attention to the potential role of exercise in the modulation of amyloid b turnover,inflammation,synthesis and release of neurotrophins,and improvements in cerebral blood flow.Promoting changes in lifestyle in presymptomatic and predementia disease stages may have the potential for delaying one-third of dementias worldwide.Multimodal interventions that include the adoption of an active lifestyle should be recommended for older populations.Adrian De la Rosa Gloria Olaso-Gonzalez Coralie Arc-Chagnaud Fernando Millan Andrea Salvador-Pascual Consolacion Garcıa-Lucerga Cristina Blasco-Lafarga Esther Garcia-Dominguez Aitor Carretero Angela G.Correas Jose Vina Mari Carmen Gomez-Cabrera 2020Journal of Sport and Health Science2020,9,5:32
3Current imaging strategies for the evaluation of uterine cervical cancer显示文摘Uterine cervical cancer still remains an important socioeconomic issue because it largely affects women of reproductive age.Prognosis is highly depended on extent of the disease at diagnosis and,therefore,accurate staging is crucial for optimal management.Cervical cancer is clinically staged,according to International Federation of Gynecology and Obstetrics guidelines,but,currently,there is increased use of cross sectional imaging modalities [computed tomography(CT),magnetic resonance imaging(MRI),positron emission tomography-CT(PET-CT)] for the study of important prognostic factors like tumor size,parametrial invasion,endocervical extension,pelvic side wall or adjacent/distal organs involvement and lymph node status.Imaging indications also include cervical cancer follow-up,evaluation of tumor response to treatment and selection of suitable candidates for less radical surgeries like radical trachelectomy for fertility preservation.The preferred imaging method for local cervical cancer evaluation is MRI;CT is equally effective for evaluation of extrauterine spread of the disease.PETCT shows high diagnostic performance for the detection of tumor relapse and metastatic lymph nodes.The aim of this review is to familiarize radiologists with the MRI appearance of cervical carcinoma and to discuss the indications of cross sectional imaging during the course of the disease in patients with cervical carcinoma.Charis Bourgioti Konstantinos Chatoupis Lia Angela Moulopoulos 2016World Journal of Radiology2016,8,4:29
4Genetic and epigenetic biomarkers for diagnosis, prognosis and treatment of colorectal cancer显示文摘Colorectal cancer(CRC)is one of the most common cancer worldwide and results from the accumulation of mutations and epimutations in colonic mucosa cells ultimately leading to cell proliferation and metastasis.Unfortunately,CRC prognosis is still poor and the search of novel diagnostic and prognostic biomarkers is highly desired to prevent CRC-related deaths.The present article aims to summarize the most recent findings concerning the use of either genetic or epigenetic(mainly related to DNA methylation)biomarkers for CRC diagnosis,prognosis,and response to treatment.Recent large-scale DNA methylation studies suggest that CRC can be divided into several subtypes according to the frequency of DNA methylation and those of mutations in key CRC genes,and that this is reflected by different prognostic outcomes.Increasing evidence suggests that the analysis of DNA methylation in blood or fecal specimens could represent a valuable non-invasive diagnostic tool for CRC.Moreover,a broad spectrum of studies indicates that the inter-individual response to chemotherapeutic treatments depends on both epigenetic modifications and genetic mutations occurring in colorectal cancer cells,thereby opening the way for a personalized medicine.Overall,combining genetic and epigenetic data might represent the most promising tool for a proper diagnostic,prognostic and therapeutic approach.Fabio Coppedè Angela Lopomo Roberto Spisni Lucia Migliore 2014World Journal of Gastroenterology2014,20,4:29

7High circulating D-dimers are associated with ascites and hepatocellular carcinoma in liver cirrhosis显示文摘AIM: To measure plasma D-dimer levels in cirrhotic patients with and without ascites, assessing the effect of ascites resolution in D-dimer concentration. METHODS: Seventy consecutive cirrhotic patients (M = 44, F = 26, mean age 65 years, SD ± 13), observed from October 2005 to March 2006 were enrolled. Circulating D-dimer levels were measured using a latex-enhanced, immunoturbidimetric test. In patients with ascites (n = 42) the test was repeated after ascites resolution. RESULTS: Ascites was present in 42 patients (group A) and absent in 28 (group B). Group A patients had more advanced liver disease. Hepatocellular carcinoma (HCC) was diagnosed in 14 patients and was more frequent in group B. Above normal range D-dimers were found in 45/70 patients. High D-dimers were more frequent in group A than in group B (P = 0.001). High D-dimers were associated with presence of HCC (P = 0.048) only in group B. After ascites resolution, obtained in all patients, mean D-dimer values decreased in those 34 patients with high basal levels (P = 0.007), returning to normal in 17. CONCLUSION: In patients with liver cirrhosis, ascites and HCC are the main factors associated with increased fibrinolytic activity.Aldo Spadaro Vincenza Tortorella Carmela Morace Agostino Fortiguerra Paola Composto Caterina Bonfiglio Angela Alibrandi Carmelo Luigiano Giuseppe De Caro Antonino Ajello Oscar Ferraù Maria Antonietta Freni 2008World Journal of Gastroenterology2008,14,10:19

9H pylori (CagA) and Epstein-Barr virus infection in gastric carcinomas:Correlation with p53 mutation and c-Myc,Bcl-2 and Bax expression显示文摘AIM: To investigate the interrelationship between H pylori and Epstein-Barr virus (EBV) infection in the gastric carcinogenesis having in focus the p53 mutation and the c-Myc, Bcl-2 and Bax expression. METHODS: seventy-one gastric carcinoma tissues were assessed by polymerase chain reaction (PCR) for H pylori and in situ hybridization for EBV. c-Myc, Bcl-2 and Bax expression were detected by immunohistochemistry and single-stranded conformational polymorphism (SSCP) for p53 mutation. RESULTS: The positivity rates for H pylori and EBV were 94.4% and 8.45%, respectively. The majority of the cases displayed only the H pylori presence. All EBV positive cases were also H pylori positive. None infectious agent was observed in 5.55% of the cases. The intestinal type tumor was more frequent in the co-infected and non-infected groups. The female predominated in the non-infected group showing statistical significance (70.4% vs 29.6%, P=0.039). The Bcl-2 was only detected in the group exclusively infected by H pylori. However, c-Myc and Bax were detected in the three groups but with a low frequency in the co-infected group. Mutation of p53 was present in all groups, with the highest frequencies in the H pylori positive groups. CONCLUSION: The frequency of H pylori infection in gastric carcinomas was high. The presented data indicated that gastric carcinogenesis has different pathways depending of the presence of the two investigated infectious agents, suggesting a possible involvement of H pylori with apoptotic process. The low expression of c-Myc and Bax in the EBV-positive groups suggests that EBV may inhibit the expression of these proteins. Nevertheless, p53 mutation shows to be a relevant alteration, independent of both infectious agents.Valeska Portela Lima Marcos Antonio Pereira de Lima Angela Rosa André Márcia Valéria Pitombeira Ferreira Marcos Aurélio Pessoa Barros Sílvia Helena Barem Rabenhorst 2008World Journal of Gastroenterology2008,14,6:17
10Pre-diagnostic levels of adiponectin and soluble vascular cell adhesion molecule-1 are associated with colorectal cancer risk显示文摘AIM: To examine the relationships between pre-diagnostic biomarkers and colorectal cancer risk and assess their relevance in predictive models.METHODS: A nested case-control study was designed to include all first primary incident colorectal cancer cases diagnosed between inclusion in the SUpplémentation en VItamines et Minéraux AntioXydants cohort in 1994 and the end of follow-up in 2007. Cases (n = 50) were matched with two randomly selected controls (n = 100). Conditional logistic regression models were used to investigate the associations between pre-diagnostic levels of hs-CRP, adiponectin, leptin, soluble vascular cell adhesion molecule-1 (sVCAM-1), soluble intercellular adhesion molecule-1, E-selectin, monocyte chemoattractant protein-1 and colorectal cancer risk. Area under the receiver operating curves (AUC) and relative integrated discrimination improvement (RIDI) statistics were used to assess the discriminatory potential of the models. RESULTS: Plasma adiponectin level was associated with decreased colorectal cancer risk (P for linear trend = 0.03). Quartiles of sVCAM-1 were associated with increased colorectal cancer risk (P for linear trend = 0.02). No association was observed with any of the other biomarkers. Compared to standard models with known risk factors, those including both adiponectin and sVCAM-1 had substantially improved performance for colorectal cancer risk prediction (P for AUC improvement = 0.01, RIDI = 26.5%). CONCLUSION: These results suggest that pre-diagnostic plasma adiponectin and sVCAM-1 levels are associated with decreased and increased colorectal cancer risk, respectively. These relationships must be confirmed in large validation studies.Mathilde Touvier Léopold Fezeu Namanjeet Ahluwalia Chantal Julia Nathalie Charnaux Angela Sutton Caroline Méjean Paule Latino-Martel Serge Hercberg Pilar Galan Sébastien Czernichow 2012World Journal of Gastroenterology2012,18,22:15
11基于流量恢复法的黄河下游鱼类生态需水研究显示文摘运用流量恢复(the flow restoration methodology)方法研究黄河下游鱼类生态需水,其基本思路是:首先获得所保护鱼类生态习性相关的流量信息,包括水深、流速、水量等.然后建立概念性模型,确定鱼类和特定流量组分之间的联系.在此基础上,确定流量目标,每一个流量目标被赋予一些水力指标,作为获得满足这个目标的环境流量计算的依据.运用水文学、水力学模型确定满足这些流量目标需要的水流条件,包括数量、持续时间、频率和发生时间,给出满足鱼类生长需要的生态流量.最后给出不同水资源管理情景下可接受的鱼类生态需水.蒋晓辉 Angela Arthington 刘昌明 2009北京师范大学学报(自然科学版)2009,45,5:15
12美国图书馆的今天:实践、趋势与挑战显示文摘目前,美国的图书馆一般都订有策略性规划,有自己的人事分类体系,建立了内部切磋交流机制和组织机构,十分重视用户工作。其发展呈现如下一些趋势:越来越多地使用电子服务方式;注重书目的双重作用;大力开展远程教育和原文传递服务;推行馆舍联合使用和采编外包及联合购买,等等。不断变化的形势,也给美国的图书馆提出了新的挑战,如如何处理科技消费问题、经费预算不稳和馆员短缺问题、资源价格高居不下和网上色情问题,等等。柯素善 顾小明 徐克谦 Angela Lew 2003中国图书馆学报2003,29,6:15

14依赖VS独立?中国消费者自我构念的地域和年龄差异及其对广告诉求偏好的影响显示文摘以往对于自我构念的研究普遍认为中国人更偏向依赖型自我。然而,随着社会和经济的日益发展,特别是改革开放和对外交流的深入,中国消费者的自我构念在不同年龄、不同地域上已逐渐发生变化。文章通过三个实验对这一问题进行了实证研究。结果显示:中国青少年的自我构念存在地域差异,即出生在大城市的青少年更偏向独立型自我,而出生在乡镇的青少年更偏向依赖型自我。此外,自我构念水平也存在年龄差异,相对于青少年而言,中年人更倾向于依赖型自我。在此基础上,文章还探讨了消费者的自我构念对不同广告诉求(趋利vs.避害)偏好的影响。张红霞 丁瑛 Angela Y.Lee 徐菁 2013营销科学学报(辑刊)2013,7,1:14
15Retrospective study on mixed neuroendocrine non-neuroendocrine neoplasms from five European centres显示文摘BACKGROUND Mixed neuroendocrine non-neuroendocrine neoplasm(MiNEN)is a rare diagnosis,mainly encountered in the gastro-entero-pancreatic tract.There is limited knowledge of its epidemiology,prognosis and biology,and the best management for affected patients is still to be defined.AIM To investigate clinical-pathological characteristics,treatment modalities and survival outcomes of a retrospective cohort of patients with a diagnosis of MiNEN.METHODS Consecutive patients with a histologically proven diagnosis of MiNEN were identified at 5 European centres.Patient data were retrospectively collected from medical records.Pathological samples were reviewed to ascertain compliance with the 2017 World Health Organisation definition of MiNEN.Tumour responses to systemic treatment were assessed according to the Response Evaluation Criteria in Solid Tumours 1.1.Kaplan-Meier analysis was applied to estimate survival outcomes.Associations between clinical-pathological characteristics and survival outcomes were explored using Log-rank test for equality of survivors functions(univariate)and Cox-regression analysis(multivariable).RESULTS Sixty-nine consecutive patients identified;Median age at diagnosis:64 years.Males:63.8%.Localised disease(curable):53.6%.Commonest sites of origin:colon-rectum(43.5%)and oesophagus/oesophagogastric junction(15.9%).The neuroendocrine component was;predominant in 58.6%,poorly differentiated in 86.3%,and large cell in 81.25%,of cases analysed.Most distant metastases analysed(73.4%)were occupied only by a poorly differentiated neuroendocrine component.Ninety-four percent of patients with localised disease underwent curative surgery;53%also received perioperative treatment,most often in line with protocols for adenocarcinomas from the same sites of origin.Chemotherapy was offered to most patients(68.1%)with advanced disease,and followed protocols for pure neuroendocrine carcinomas or adenocarcinomas in equal proportion.In localised cases,median recurrence free survival(RFS);14.0 months(95%CI:9.2-24.4),and median overall survival(OS):28.6 months(95%CI:18.3-41.1).On univariate analysis,receipt of perioperative treatment(vs surgery alone)did not improve RFS(P=0.375),or OS(P=0.240).In advanced cases,median progression free survival(PFS);5.6 months(95%CI:4.4-7.4),and median OS;9.0 months(95%CI:5.2-13.4).On univariate analysis,receipt of palliative active treatment(vs best supportive care)prolonged PFS and OS(both,P<0.001).CONCLUSION MiNEN is most commonly driven by a poorly differentiated neuroendocrine component,and has poor prognosis.Advances in its biological understanding are needed to identify effective treatments and improve patient outcomes.Melissa Frizziero Xin Wang Bipasha Chakrabarty Alexa Childs Tu V Luong Thomas Walter Mohid S Khan Meleri Morgan Adam Christian Mona Elshafie Tahir Shah Annamaria Minicozzi Wasat Mansoor Tim Meyer Angela Lamarca Richard A Hubner Juan W Valle Mairéad G McNamara 2019World Journal of Gastroenterology2019,25,39:13
16Diagnosis of gastrointestinal bleeding: A practical guide for clinicians显示文摘Gastrointestinal bleeding is a common problem encountered in the emergency department and in the primary care setting. Acute or overt gastrointestinal bleeding is visible in the form of hematemesis, melena or hematochezia. Chronic or occult gastrointestinal bleeding is notapparent to the patient and usually presents as positive fecal occult blood or iron deficiency anemia. Obscure gastrointestinal bleeding is recurrent bleeding when the source remains unidentified after upper endoscopy and colonoscopic evaluation and is usually from the small intestine. Accurate clinical diagnosis is crucial and guides definitive investigations and interventions. This review summarizes the overall diagnostic approach to gastrointestinal bleeding and provides a practical guide for clinicians.Bong Sik Matthew Kim Bob T Li Alexander Engel Jaswinder S Samra Stephen Clarke Ian D Norton Angela E Li 2014World Journal of Gastrointestinal Pathophysiology2014,5,4:13
17体力活动、久坐、身体素质与1型和2型糖尿病年轻患者健康预后的关系:对流行病学文献的综述(英文)显示文摘Diabetes is a leading chronic disease of childhood and adolescence.In addition to the well-known auto-immune,insulin-dependent diabetes mellitus(type 1 diabetes(T1D)),the past two decades have witnessed the emergence of type 2 diabetes(T2D) in children and adolescents,which previously was only seen in middle-aged or older adults.One of the key components of diabetes management is physical activity(PA).The beneficial effects of increased PA and decreased sedentary behavior are extremely important in youth with diabetes because of the markedly increased long-term risk of cardiovascular disease in this population compared to persons without diabetes.This review aims to comprehensively summarize the epidemiologic,observational research published and listed in PubMed between 1970 and 2012 on PA and sedentary behaviors,as well as physical fitness in children and adolescents with TID and T2D.Additionally,we describe briefly the state of knowledge on perceived barriers of PA in persons with diabetes,with a focus on hypoglycemia.Finally,we provide an overview of the epidemiological literature pertaining to health benefits of increased PA in youth with TID and T2D and briefly discuss the topic of exercise-related hypoglycemia.Angela D.

18Current trends in management of hepatitis B virus reactivation in the biologic therapy era显示文摘Hepatitis B virus (HBV) reactivation represents an emerging cause of liver disease in patients undergoing treatment with biologic agents. In particular, the risk ofHBV reactivation is heightened by the use monoclonalantibodies, such as rituximab (anti-CD20) and alemtuzumab (anti-CD52) that cause profound and longlasting immunosuppression. Emerging data indicatethat HBV reactivation could also develop following theuse of other biologic agents, such as tumor necrosis factor (TNF)-α inhibitors. When HBV reactivation is di-agnosed, it is mandatory to suspend biologic treatmentand start antiviral agents immediately. However, preemptive antiviral therapy prior to monoclonal antibodyadministration is crucial in preventing HBV reactivationand its clinical consequences. Several lines of evidencehave shown that risk of HBV reactivation is greatlyreduced by the identifi cation of high-risk patients andthe use of prophylactic antiviral therapy. In this article, we discuss current trends in the management of HBV reactivation in immunosuppressed patients receiving biologic therapy, such as rituximab, alemtuzumab and TNF-α antagonists.Claudio M Mastroianni Miriam Lichtner Rita Citton Cosmo Del Borgo Angela Rago Helene Martini Giuseppe Cimino Vincenzo Vullo 2011World Journal of Gastroenterology2011,17,34:12
19Nutritional effects of the dietary inclusion of partially defatted Hermetia illucens larva meal in Muscovy duck显示文摘Background: The present work is aimed at evaluating the effect of different inclusion levels of a partially defatted black soldier fly(Hermetia illucens,L.;HI) larva meal for ducks.A total of 192 female 3-day-old Muscovy ducklings(Cairina moschata domestica,Canedins R71 L White,Grimaud Freres Selection,France) were divided into 4 groups,assigned 4 different dietary treatments(6 replicates/treatment and 8 birds/replicate) and reared from 3 to 50 days of age.HI larva meal was included at increasing levels(0,3%,6% and 9%,HI0,HI3,HI6 and HI9,respectively) in isonitrogenous and isoenergetic diets formulated for 3 feeding phases: starter(3–17 days of age),grower(18–38 days of age) and finisher(39–50 days of age).The growth performance and apparent total tract digestibility were evaluated during the trial using titanium dioxide as an inert marker(0.3% of inclusion).At 51 days of age,two birds per pen were slaughtered and histomorphological investigations were performed.Results: The live weight and average daily gain showed a quadratic response to increasing HI meal in the grower period(minimum corresponding to the HI6 group).No effects of dietary inclusion levels were observed for the daily feed intake or feed conversion ratio.The apparent dry matter and organic matter digestibility were not affected by the dietary treatment.A linear decrease was observed for the crude protein apparent digestibility in the starter period(minimum for the HI9 groups).The ether extract apparent digestibility increased linearly during the grower and finisher periods(minimum for the HI0 group).The morphometric indices were not influenced by the dietary treatments.Conclusions: The inclusion of up to 9% of HI partially defatted larva meal in the diet of ducks did not cause any effect on growth performance,as well as the apparent digestibility.Moreover,dietary HI inclusion preserved the physiological intestinal development.Marta Gariglio Sihem Dabbou Ilaria Biasato Maria Teresa Capucchio Elena Colombino Fuensanta Hernandez Josefa Madrid Silvia Martinez Francesco Gai Christian Caimi Sara Bellezza Oddon Marco Meneguz Angela Trocino Riccardo Vincenzi Laura Gasco Achille Schiavone 2019Journal of Animal Science and Biotechnology2019,10,3:12
20Hepatitis B vaccine by intradermal route in non responder patients:An update显示文摘Vaccination is the main prophylactic measure to reduce the mortality caused by hepatitis B virus(HBV)infection in healthy subjects since the immune response to hepatitis B recombinant vaccination occurs in over 90%of general population.Individuals who develop an antiHBs titer less than 10 mIU/mL after primary vaccination cycle are defined'no responders'.Many factors could cause a non response to the HBV vaccination,such as administration of the vaccine in buttocks,impaired vaccine storage conditions,drug abuse,smoking,infections and obesity.Moreover there are some diseases,like chronic kidney disease,human immunodeficiency virus infection,chronic liver disease,celiac disease,thalassaemia,typeⅠdiabetes mellitus,down’s syndrome and other forms of mental retardation that are characterized by a poorer response to HBV vaccination than healthy subjects.To date it is still unclear how to treat this group of patients at high risk of hepatitis B infection.Recent studies seem to indicate that the administration of HBV recombinant vaccine by the intradermal route is very effective and could represent a more useful strategy than intramuscular route.This review focuses on the use of anti hepatitis B vaccine by intradermal route as alternative to conventional intramuscular vaccine in all non responder patients.A comprehensive review of the literature using PubMed database,with appropriate terms,was undertaken for articles in English published since 1983.The literature search was undertaken in September 2013.Martina Filippelli Elena Lionetti Alessia Gennaro Angela Lanzafame Teresa Arrigo Carmelo Salpietro Mario La Rosa Salvatore Leonardi 2014World Journal of Gastroenterology2014,20,30:12
