1Pathogenesis and clinical management of Helicobacter pylori gastric infection显示文摘Helicobacter pylori(H.pylori)is a gram-negative bacterium that infects approximately 4.4 billion individuals worldwide.However,its prevalence varies among different geographic areas,and is influenced by several factors.The infection can be acquired by means of oral-oral or fecal-oral transmission,and the pathogen possesses various mechanisms that improve its capacity of mobility,adherence and manipulation of the gastric microenvironment,making possible the colonization of an organ with a highly acidic lumen.In addition,H.pylori presents a large variety of virulence factors that improve its pathogenicity,of which we highlight cytotoxin associated antigen A,vacuolating cytotoxin,duodenal ulcer promoting gene A protein,outer inflammatory protein and gamma-glutamyl transpeptidase.The host immune system,mainly by means of a Th1-polarized response,also plays a crucial role in the infection course.Although most H.pylori-positive individuals remain asymptomatic,the infection predisposes the development of various clinical conditions as peptic ulcers,gastric adenocarcinomas and mucosa-associated lymphoid tissue lymphomas.Invasive and non-invasive diagnostic methods,each of them with their related advantages and limitations,have been applied in H.pylori detection.Moreover,bacterial resistance to antimicrobial therapy is a major challenge in the treatment of this infection,and new therapy alternatives are being tested to improve H.pylori eradication.Last but not least,the development of effective vaccines against H.pylori infection have been the aim of several research studies.Breno Bittencourt de Brito Filipe Ant?nio Fran?a da Silva Aline Silva Soares Vinícius Afonso Pereira Maria Luísa Cordeiro Santos Mariana Miranda Sampaio Pedro Henrique Moreira Neves Fabrício Freire de Melo 2019World Journal of Gastroenterology2019,25,37:84
2Portal vein thrombosis:Insight into physiopathology,diagnosis,and treatment显示文摘Portal vein thrombosis (PVT) is a relatively common complication in patients with liver cirrhosis, but might also occur in absence of an overt liver disease. Several causes, either local or systemic, might play an important role in PVT pathogenesis. Frequently, more than one risk factor could be identified; however, occasionally no single factor is discernable. Clinical examination, laboratory investigations, and imaging are helpful to provide a quick diagnosis, as prompt treatment might greatly affect a patient's outcome. In this review, we analyze the physiopathological mechanisms of PVT development, together with the hemodynamic and functional alterations related to this condition. Moreover, we describe the principal factors most frequently involved in PVT development and the recent knowledge concerning diagnostic and therapeutic procedures. Finally, we analyze the implications of PVT in the setting of liver transplantation and its possible influence on patients' future prognoses.Francesca R Ponziani Maria A Zocco Chiara Campanale Emanuele Rinninella Annalisa Tortora Luca Di Maurizio Giuseppe Bombardieri Raimondo De Cristofaro Anna M De Gaetano Raffaele Landolfi Antonio Gasbarrini 2010World Journal of Gastroenterology2010,16,2:75
3Canopy Temperature Depression as a Potential Selection Criterion for Drought Resistance in Wheat显示文摘Field studies were conducted at Bushland, Texas, USA, in 2004 to examine usefulness of canopy temperature depression(CTD), the difference of air-canopy temperature, in screening wheat (Triticum aestivum L.) genotypes for yield underdryland and irrigated. Forty winter wheat genotypes were grown under irrigation and dryland. CTDs were recorded afterheading between 1 330 and 1 530 h on 6 clear days for dryland and 9 days for irrigation. Drought susceptible index (DSI)for each genotype was calculated using mean yield under dryland and irrigated conditions. Genotypes exhibited greatdifferences in CTD under each environment. The dryland CTDs averaged 1.33°C ranging from -0.67 to 2.57°C, and theaverage irrigation CTD were 4.59°C ranging from 3.21 to 5.62°C. A low yield reduction was observed under drylandconditions relative to irrigated conditions for high-CTD genotypes. CTD values were highly negatively correlated withDSI under dryland, and genotypes of CTDs = 1.3°C in dryland condition were identified as drought resistant. For 21genotypes classified as drought resistant by DSI, their CTDs were 1.68°C for dryland and 4.35°C for irrigation on average;for 19 genotypes classified as drought susceptible by DSI, average CTD was 0.94°C in dryland and 4.85°C in irrigation.The high-yield genotypes consistently had high CTD values, and the low-yield ones had low CTD values for allmeasurements in dryland. After heading, genotypes maintained consistent ranking for CTD. Regression results for CTDand yield suggested that the best time for taking CTD measurement was 3-4 weeks after heading in irrigation but any timebefore senescence in dryland. Crop water stress index (CWSI) calculated from CTD data was highly correlated with CWSIcalculated from yield, which suggesting traditional costly CWSI measurement may be improved by using portable infraredthermometers. Most importantly, grain yield was highly correlated with CTD under dryland (R2 = 0.79-0.86) and irrigation(R2 = 0.46-0.58) conditions. These results clearly indicated grain yield and water stress can be predicted by taking CTDvalues in field, which can be used by breeding programs as a potential selection criterion for grain yield and droughtresistance in wheat, but a second study year is needed to confirm further.FAN Ting-lu Maria Balta Jackie Rudd William A Payne 2005Agricultural Sciences in China2005,4,10:35
4Helicobacter pylori infection: Beyond gastric manifestations显示文摘Helicobacter pylori(H.pylori)is a bacterium that infects more than a half of world’s population.Although it is mainly related to the development of gastroduodenal diseases,several studies have shown that such infection may also influence the development and severity of various extragastric diseases.According to the current evidence,whereas this bacterium is a risk factor for some of these manifestations,it might play a protective role in other pathological conditions.In that context,when considered the gastrointestinal tract,H.pylori positivity have been related to Inflammatory Bowel Disease,Gastroesophageal Reflux Disease,Non-Alcoholic Fatty Liver Disease,Hepatic Carcinoma,Cholelithiasis,and Cholecystitis.Moreover,lower serum levels of iron and vitamin B12 have been found in patients with H.pylori infection,leading to the emergence of anemias in a portion of them.With regards to neurological manifestations,a growing number of studies have associated that bacterium with multiple sclerosis,Alzheimer’s disease,Parkinson’s disease,and Guillain-Barrésyndrome.Interestingly,the risk of developing cardiovascular disorders,such as atherosclerosis,is also influenced by the infection.Besides that,the H.pylori-associated inflammation may also lead to increased insulin resistance,leading to a higher risk of diabetes mellitus among infected individuals.Finally,the occurrence of dermatological and ophthalmic disorders have also been related to that microorganism.In this sense,this minireview aims to gather the main studies associating H.pylori infection with extragastric conditions,and also to explore the main mechanisms that may explain the role of H.pylori in those diseases.Maria Luisa Cordeiro Santos Breno Bittencourt de Brito Filipe Antonio França da Silva Mariana Miranda Sampaio Hanna Santos Marques Natalia Oliveira e Silva Dulciene Maria de Magalhaes Queiroz Fabricio Freire de Melo 2020World Journal of Gastroenterology2020,26,28:34
5Comparative review of vertebroplasty and kyphoplasty显示文摘The aim of this review is to compare the effectiveness of percutaneous vertebroplasty and kyphoplasty to treat pain and improve functional outcome from ver-tebral fractures secondary to osteoporosis and tumor conditions. In 2009, two open randomized controlled trials published in the New England Journal of Medicine questioned the value of vertebroplasty in treating ver-tebral compression fractures. Nevertheless, the prac-tice of physicians treating these conditions has barely changed. The objective of this review is to try to clarify the most important issues, based on our own experi-ence and the reported evidence about both techniques, and to guide towards the most appropriate choice of treatment of vertebral fractures, although many ques-tions still remain unanswered.Ferno Ruiz Santiago Alicia Santiago Chinchilla Luis Guzmán álvarez Antonio Luis Pérez Abela Maria del Mar Castellano García Miguel Pajares López 2014World Journal of Radiology2014,6,6:30

7Risk factors associated with the development of ischemic colitis显示文摘AIM:To ascertain the role of cardiovascular risk factors,cardiovascular diseases,standard treatments and other diseases in the development of ischemic colitis(IC).METHODS:A retrospective,case-control study was designed,using matched data and covering 161 incident cases of IC who required admission to our hospital from 1998 through 2003.IC was diagnosed on the basis of endoscopic findings and diagnostic or compatible his-tology.Controls were randomly chosen from a cohort of patients who were admitted in the same period and required a colonoscopy,excluding those with diagnosis of colitis.Cases were matched with controls(ratio 1:2),by age and sex.A conditional logistic regression was performed.RESULTS:A total of 483 patients(161 cases,322 con-trols)were included;mean age 75.67±10.03 years,55.9%women.The principal indications for colonos-copy in the control group were lower gastrointestinal hemorrhage(35.4%),anemia(33.9%),abdominal pain(19.9%)and diarrhea(9.6%).The endoscopic findings in this group were hemorrhoids(25.5%),diverticular disease(30.4%),polyps(19.9%)and colorectal cancer(10.2%).The following variables were associated with IC in the univariate analysis:arterial hypertension(P= 0.033);dyslipidemia(P<0.001);diabetes mellitus(P =0.025);peripheral arterial disease(P=0.004);heart failure(P=0.026);treatment with hypotensive drugs(P=0.023);angiotensin-converting enzyme inhibitors;(P=0.018);calcium channel antagonists(P=0.028);and acetylsalicylic acid(ASA)(P<0.001).Finally,the following variables were independently associated with the development of IC:diabetes mellitus[odds ratio(OR)1.76,95%confidence interval(CI):1.001-3.077,P=0.046];dyslipidemia(OR 2.12,95%CI:1.26-3.57,P=0.004);heart failure(OR 3.17,95%CI:1.31-7.68,P=0.01);peripheral arterial disease(OR 4.1,95%CI:1.32-12.72,P=0.015);treatment with digoxin(digitalis)(OR 0.27,95%CI:0.084-0.857,P=0.026);and ASA(OR 1.97,95%CI:1.16-3.36,P=0.012).CONCLUSION:The development of an episode of IC was independently associated with diabetes,dyslipid-emia,presence of heart failure,peripheral arterial dis-ease and treatment with digoxin or ASA.Joaquín Cubiella Fernández Luisa Núez Calvo Elvira González Vázquez Maria Jesús García García Maria Teresa Alves Pérez Isabel Martínez Silva Javier Fernández Seara 2010World Journal of Gastroenterology2010,16,36:27
8History of the infantile hepatic hemangioma:From imaging to generating a differential diagnosis显示文摘We aim to provide an up-to-date summary of infantile hepatic hemangioma(IHH) and its misnomers and to dialectically present the differential diagnosis of these rare entities of the liver.Eligible peer-reviewed articles on hepatic infantile hemangiomas,published between 2000 and 2015,were reviewed for this study.IHH is the most common hepatic vascular tumor in children.Once a liver mass is identified in an infant,the differential diagnosis ranges from vascular malformations to benign and malignant tumors including mesenchymal hamartoma,hepatoblastoma,metastatic neuroblastoma,so careful physical examination,imaging studies,and,if indicated,tumor markers and biopsy,are of pivotal importance to ascertain the correct diagnosis.Despite the benign nature of IHHs,some of these lesions may demand medical and/or surgical intervention,especially for multiple and diffuse IHH.Complications can include hepatomegaly,hypothyroidism and cardiac failure.Therefore,a close follow-up is required until complete involution of the lesions.We propose an algorithm to guide the physicians towards the proper management of hepatic lesions.Maria Gnarra Gerald Behr Alison Kitajewski June K Wu Sudha A Anupindi Carrie J Shawber Nick Zavras Dimitrios Schizas Chris Salakos Konstantinos P Economopoulos 2016World Journal of Clinical Pediatrics2016,5,3:27
9Alcoholic liver disease:Utility of animal models显示文摘Alcoholic liver disease(ALD) is a major cause of acute and chronic liver injury. Extensive evidence has been accumulated on the pathological process of ALD during the past decades. However, effective treatment options for ALD are very limited due to the lack of suitable in vivo models that recapitulate the full spectrum of ALD. Experimental animal models of ALD, particularly rodents, have been used extensively to mimic human ALD. An ideal animal model should recapitulate all aspects of the ALD process, including significant steatosis, hepatic neutrophil infiltration, and liver injury. A better strategy against ALD depends on clear diagnostic biomarkers, accurate predictor(s) of its progression and new therapeutic approaches to modulate stop or even reverse the disease. Numerous models employing rodent animals have been established in the last decades to investigate the effects of acute and chronic alcohol exposure on the initiation and progression of ALD. Although significant progress has been made in gaining better knowledge on the mechanisms and pathology of ALD, many features of ALD are unknown, and require further investigation, ideally with improved animal models that more effectively mimic human ALD. Although differences in the degree and stages of alcoholic liver injury inevitably exist between animal models and human ALD, the acquisition and translational relevance will be greatly enhanced with the development of new and improved animal models of ALD.Arantza Lamas-Paz Fengjie Hao Leonard J Nelson Maria Teresa Vázquez Santiago Canals Manuel Gómez del Moral Eduardo Martínez-Naves Yulia A Nevzorova Francisco Javier Cubero 2018World Journal of Gastroenterology2018,24,45:26
10Device-associated infection rates, mortality, length of stay and bacterial resistance in intensive care units in Ecuador: International Nosocomial Infection Control Consortium's findings显示文摘AIM To report the results of the International Nosocomial Infection Control Consortium(INICC) study conducted in Quito, Ecuador.METHODS A device-associated healthcare-acquired infection(DAHAI) prospective surveillance study conducted from October 2013 to January 2015 in 2 adult intensive care units(ICUs) from 2 hospitals using the United States Centers for Disease Control/National Healthcare Safety Network(CDC/NHSN) definitions and INICC methods. RESULTS We followed 776 ICU patients for 4818 bed-days. The central line-associated bloodstream infection(CLABSI) rate was 6.5 per 1000 central line(CL)-days, the ventilator-associated pneumonia(VAP) rate was 44.3 per 1000 mechanical ventilator(MV)-days, and the catheterassociated urinary tract infection(CAUTI) rate was 5.7 per 1000 urinary catheter(UC)-days. CLABSI and CAUTI rates in our ICUs were similar to INICC rates [4.9(CLABSI) and 5.3(CAUTI)] and higher than NHSN rates [0.8(CLABSI) and 1.3(CAUTI)]- although device use ratios for CL and UC were higher than INICC and CDC/NSHN's ratios. By contrast, despite the VAP rate was higher than INICC(16.5) and NHSN's rates(1.1), MV DUR was lower in our ICUs. Resistance of A. baumannii to imipenem and meropenem was 75.0%, and of Pseudomonas aeruginosa to ciprofloxacin and piperacillin-tazobactam was higher than 72.7%, all them higher than CDC/NHSN rates. Excess length of stay was 7.4 d for patients with CLABSI, 4.8 for patients with VAP and 9.2 for patients CAUTI. Excess crude mortality in ICUs was 30.9% for CLABSI, 14.5% for VAP and 17.6% for CAUTI. CONCLUSION DA-HAI rates in our ICUs from Ecuador are higher than United States CDC/NSHN rates and similar to INICC international rates.Estuardo Salgado Yepez Maria M Bovera Victor D Rosenthal Hugo A González Flores Leonardo Pazmino Francisco Valencia Nelly Alquinga Vanessa Ramirez Edgar Jara Miguel Lascano Veronica Delgado Cristian Cevallos Gasdali Santacruz Cristian Pelaéz Celso Zaruma Diego Barahona Pinto 2017World Journal of Biological Chemistry2017,8,1:23

12Microbiota modification by probiotic supplementation reduces colitis associated colon cancer in mice显示文摘AIM To investigate the effect of probiotic supplementation during the development of an experimental model of colitis associated colon cancer(CAC). METHODS C57 BL/6 mice received an intraperitoneal injection of azoxymethane(10 mg/kg), followed by three cycles of sodium dextran sulphate diluted in water(5% w/v). Probiotic group received daily a mixture of Lactobacillus acidophilus, Lactobacil us rhamnosus and Bifidobacterium bifidum. Microbiota composition was assessed by 16 Sr RNA Illumina Hi Seq sequencing. Colon samples were collected for histological analysis. Tumor cytokines was assessed by Real Time-PCR(Polymerase Chain Reaction); and serum cytokines by Multiplex assay. All tests were two-sided. The level of significance was set at P < 0.05. Graphs were generated and statistical analysis performed using the software Graph Pad Prism 5.0. The project was approved by the institutional review board committee. RESULTS At day 60 after azoxymethane injection, the mean number of tumours in the probiotic group was 40% lower than that in the control group, and the probiotic group exhibited tumours of smaller size(< 2 mm)(P < 0.05). There was no difference in richness and diversity between groups. However, there was a significant difference in beta diversity in the multidimensional scaling analysis. The abundance of the genera Lactobacillus, Bifidobacterium, Allobaculum, Clostridium XI and Clostridium XVⅢ increased in the probiotic group(P < 0.05). The microbial change was accompanied by reduced colitis, demonstrated by a 46% reduction in the colon inflammatory index; reduced expression of the serum chemokines RANTES and Eotaxin; decreased p-IKK and TNF-α and increased IL-10 expression in the colon. CONCLUSION Our results suggest a potential chemopreventive effect of probiotic on CAC. Probiotic supplementation changes microbiota structure and regulates the inflammatory response, reducing colitis and preventing CAC.Maria Carolina S Mendes Daiane SM Paulino Sandra R Brambilla Juliana A Camargo Gabriela F Persinoti José Barreto C Carvalheira 2018World Journal of Gastroenterology2018,24,18:17
13Damage control orthopaedics: State of the art显示文摘Damage control orthopaedics(DCO) originally consisted of the provisional immobilisation of long bone-mainly femur-fractures in order to achieve the advantages of early treatment and to minimise the risk of complications, such as major pain, fat embolism, clotting, pathological inflammatory response, severe haemorrhage triggering the lethal triad, and the traumatic effects of major surgery on a patient who is already traumatised(the 'second hit' effect). In recent years, new locations have been added to the DCO concept, such as injuries to the pelvis, spine and upper limbs. Nonetheless, this concept has not yet been validated in well-designed prospective studies, and much controversy remains.Indeed, some researchers believe the indiscriminate application of DCO might be harmful and produce substantial and unnecessary expense. In this respect, too,normalised parameters associated with the acid-base system have been proposed,under a concept termed early appropriate care, in the view that this would enable patients to receive major surgical procedures in an approach offering the advantages of early total care together with the apparent safety of DCO. This paper discusses the diagnosis and treatment of severely traumatised patients managed in accordance with DCO and highlights the possible drawbacks of this treatment principle.Enrique Guerado Maria Luisa Bertrand Juan Ramon Cano Ana María Cerván Adolfo Galán 2019World Journal of Orthopedics2019,10,1:16
14Computed tomography-guided percutaneous core needle biopsy in pancreatic tumor diagnosis显示文摘AIM: To evaluate the techniques, results, and complications related to computed tomography(CT)-guided percutaneous core needle biopsies of solid pancreatic lesions.METHODS: CT-guided percutaneous biopsies of solid pancreatic lesions performed at a cancer reference center between January 2012 and September 2013 were retrospectively analyzed. Biopsy material was collected with a 16-20 G Tru-Core needle(10-15 cm; Angiotech, Vancouver, CA) using a coaxial system and automatic biopsy gun. When direct access to the lesion was not possible, indirect(transgastric or transhepatic) access or hydrodissection and/or pneumodissection maneuvers were used. Characteristics of the patients, lesions, procedures, and histologic results were recorded using a standardized form. RESULTS: A total of 103 procedures included in the study were performed on patients with a mean age of 64.8 year(range: 39-94 year). The mean size of the pancreatic lesions was 45.5 mm(range: 15-195 mm). Most(75/103, 72.8%) procedures were performed via direct access, though hydrodissection and/or pneumodissection were used in 22.2%(23/103) of cases and indirect transhepatic or transgastric access was used in 4.8%(5/103) of cases. Histologic analysis was performed on all biopsies, and diagnoses were conclusive in 98.1%(101/103) of cases, confirming3.9%(4/103) of tumors were benign and 94.2%(97/103) were malignant; results were atypical in 1.9%(2/103) of cases, requiring a repeat biopsy to diagnose a neuroendocrine tumor, and surgical resection to confirm a primary adenocarcinoma. Only mild/moderate complications were observed in 9/103 patients(8.7%),and they were more commonly associated with biopsies of lesions located in the head/uncinate process(n =8), than of those located in the body/tail(n = 1) of the pancreas, but this difference was not significant.CONCLUSION: CT-guided biopsy of a pancreatic lesion is a safe procedure with a high success rate, and is an excellent option for minimally invasive diagnosis.Chiang J Tyng Maria Fernanda A Almeida Paula NV Barbosa Almir GV Bitencourt José Augusto AG Berg Macello S Maciel Felipe JF Coimbra Luiz Henrique O Schiavon Maria Dirlei Begnami Marcos D Guimares Charles E Zurstrassen Rubens Chojniak 2015World Journal of Gastroenterology2015,21,12:14

16Therapeutic options for the management of pancreatic cancer显示文摘Since its initial characterization, pancreatic ductal adenocarcinoma has remained one of the most devastating and difficult cancers to treat. Pancreatic cancer is the fourth leading cause of death in the United States, resulting in an estimated 38460 deaths annually. With few screening tools available to detect this disease at an early stage, 94% of patients will die within five years of diagnosis. Despite decades of research that have led to a better understanding of the molecular and cellular signaling pathways in pancreatic cancer cells, few effective therapies have been developed to target these pathways. Other treatment options have included more sophisticated pancreatic cancer surgeries and combination therapies. While outcomes have improved modestly for these patients, more effective treatmentsare desperately needed. One of the greatest challenges in the future of treating this malignancy will be to develop therapies that target the tumor microenvironment and surrounding pancreatic cancer stem cells in addition to pancreatic cancer cells. Recent advances in targeting pancreatic stellate cells and the stroma have encouraged researchers to shift their focus to the role of desmoplasia in pancreatic cancer pathobiology in the hopes of developing newer-generation therapies. By combining novel agents with current cytotoxic chemotherapies and radiation therapy and personalizing them to each patient based on specific biomarkers, the goal of prolonging a patient's life could be achieved. Here we review the most effective therapies that have been used for the treatment of pancreatic cancer and discuss the future potential of therapeutic options.Maria L Rossi Azeem A Rehman Christopher S Gondi 2014World Journal of Gastroenterology2014,20,32:13

18Peri-nuclear antibodies correlate with survival in Greek primary biliary cirrhosis patients显示文摘AIM:To investigate possible associations of anti-nuclear envelope antibody(ANEA)with disease severity and survival in Greek primary biliary cirrhosis(PBC)patients.METHODS:Serum samples were collected at diagnosis from 147 PBC patients(85%female),who were followed-up for a median 89.5 mo(range 1-240).ANEA were detected with indirect immunofluorescence on 1% formaldehyde fixed Hep2 cells,and anti-gp210 antibodies were detected using an enzyme linked immunosorbent assay.Findings were correlated with clinical data,histology,and survival.RESULTS:ANEA were detected in 69/147(46.9%) patients and 31/147(21%)were also anti-gp210 positive.The ANEA positive patients were at a more advanced histological stage(Ⅰ-Ⅱ/Ⅲ-Ⅳ56.5%/43.5% vs 74.4%/25.6%,P=0.005)compared to the ANEA negative ones.They had a higher antimitochondrial antibodies(AMA)titer(≤1:160/>1:160 50.7%/49.3%vs 71.8%/28.2%,P=0.001)and a lower survival time(91.7 ±50.7 mo vs 101.8±55 mo,P=0.043).Moreover,they had more advanced fibrosis,portal inflammation,interface hepatitis,and proliferation of bile ductules(P =0.008,P=0.008,P=0.019,and P=0.027,respectively).They also died more frequently of hepatic failure and/or hepatocellular carcinoma(P=0.016).ANEA positive,anti-gp210 positive patients had a difference in stage(Ⅰ-Ⅱ/Ⅲ-Ⅳ54.8%/45.2%vs 74.4%/25.6%,P= 0.006),AMA titer(≤1:160/>1:160 51.6%/48.4%vs 71.8%/28.2%,P=0.009),survival(91.1±52.9 mo vs 101.8±55 mo,P=0.009),and Mayo risk score(5.5 ±1.9 vs 5.04±1.3,P=0.04)compared to the ANEA negative patients.ANEA positive,anti-gp210 negative patients had a difference in AMA titer(≤1:160/>1:160 50%/50%vs 71.8%/28.2%,P=0.002),stage(Ⅰ-Ⅱ/Ⅲ -Ⅳ57.9%/42.1%vs 74.4%/25.6%,P=0.033),fibrosis(P=0.009),portal inflammation(P=0.018),interface hepatitis(P=0.032),and proliferation of bile ductules(P=0.031).Anti-gp210 positive patients had a worse Mayo risk score(5.5±1.9 vs 4.9±1.7,P=0.038)than the anti-gp210 negative ones.CONCLUSION:The presence of ANEA and anti-gp210 identifies a subgroup of PBC patients with advanced disease severity and poor prognosis.Ourania Sfakianaki Meri Koulentaki Maria Tzardi Elena Tsangaridou Panayotis A Theodoropoulos Elias Castanas Elias A Kouroumalis 2010World Journal of Gastroenterology2010,16,39:11
19Ear therapy and massage therapy in the elderly with dementia: a pilot study显示文摘OBJECTIVE: To assess the impact of massage versus ear acupuncture on behavior and participation in occupational therapy of dementia patients. METHODS: We performed a controlled, randomized longitudinal trial approved by the Bioethics Commission of the University of Extremadura. One hundred twenty elderly subjects with dementia institutionalized in residential homes in Extremadura (Spain) received treatment based on massage and ear acupuncture over three months. Behavior alterations, sleep disturbance, and participation in rehabilitation and eating were assessed every month during the three months of intervention, and at one and two months of follow-up after the end of treatment. The assessment was performed through a structured questionnaire with closed format ques-tions done by an occupational therapist not involved in the study. RESULTS: There was a statistically significant positive effect of massage and ear acupuncture (P< 0.001) on measured variables in the third month of intervention, which were maintained at two months after completing the treatment (P<0.021), when compared to the control group. CONCLUSION: Massage therapy and ear acupuncture can improve behavior and sleep disturbances, and increase the participation in eating and rehabilitation organized in residential homes, in dementia patients.Juan Rodríguez-Mansilla María Victoria González-LópezArza Enrique Varela-Donoso Jesús Montanero-Fernández María Jiménez-Palomares Elisa Maria Garrido-Ardila 2013Journal of Traditional Chinese Medicine2013,33,4:11
20Prevalence of occult hepatitis B virus infection显示文摘Occult hepatitis B virus(HBV) infection(OBI) is characterized by the persistence of HBV DNA in the liver tissue in individuals negative for the HBV surface antigen.The prevalence of OBI is quite variable depending on the level of endemic disease in different parts of the world,the different assays utilized in the studies,and the different populations studied.Many studies have been carried out on OBI prevalence in different areas of the world and categories of individuals.The studies show that OBI prevalence seems to be higher among subjects at high risk for HBV infection and with liver disease than among individuals at low risk of infection and without liver disease.Maria Luisa Gutiérrez-García Conrado M Fernandez-Rodriguez Jose Luis Lledo-Navarro Ingrid Buhigas-Garcia 2011World Journal of Gastroenterology2011,17,12:10
