2Rotational assisted endoscopic retrograde cholangiopancreatography in patients with reconstructive gastrointestinal surgical anatomy显示文摘AIM: To evaluate the success rates of performing therapy utilizing a rotational assisted enteroscopy device in endoscopic retrograde cholangiopancreatography(ERCP) in surgically altered anatomy patients. METHODS: Between June 1, 2009 and November 8, 2012, we performed 42 ERCPs with the use of rotational enteroscopy for patients with altered anatomy(39 with gastric bypass Roux-en-Y, 2 with Billroth Ⅱ gastrectomy, and 1 with hepaticojejunostomy associated with liver transplant). The indications for ERCP were: choledocholithiasis: 13 of 42(30.9%), biliary obstruction suggested on imaging: 20 of 42(47.6%), suspected sphincter of Oddi dysfunction: 4 of 42(9.5%), abnormal liver enzymes: 1 of 42(2.4%), ascending cholangitis: 2 of 42(4.8%), and bile leak: 2 of 42(4.8%). All procedures were completed with the Olympus SIF-Q180 enteroscope and the Endo-Ease Discovery SB overtube produced by Spirus Medical. RESULTS: Successful visualization of the major ampulla was accomplished in 32 of 42 procedures(76.2%). Cannulation of the bile duct was successful in 26 of 32 procedures reaching the major ampulla(81.3%). Successful therapeutic intervention was completed in 24 of 26 procedures in which the bileduct was cannulated(92.3%). The overall intention to treat success rate was 64.3%. In terms of cannulation success, the intention to treat success rate was 61.5%. Ten out of forty two patients(23.8%) required admission to the hospital after procedure for abdominal pain and nausea, and 3 of those 10 patients(7.1%) had a diagnosis of post-ERCP pancreatitis. The average hospital stay was 3 d.CONCLUSION: It is reasonable to consider an attempt at rotational assisted ERCP prior to a surgical intervention to alleviate biliary complications in patients with altered surgical anatomy.Majed El Zouhairi James B Watson Svetang V Desai David K Swartz Alejandra Castillo-Roth Mahfuzul Haque Paul S Jowell Malcolm S Branch Rebecca A Burbridge 2015World Journal of Gastrointestinal Endoscopy2015,7,3:10
3Overview, prevention and management of chemotherapy extravasation显示文摘Chemotherapy extravasation remains an accidental complication of chemotherapy administration and may result in serious damage to patients. We review in this article the clinical aspects of chemotherapy extravasation and latest advances in definitions, classification, pre-vention, management and guidelines. We review the grading of extravasation and tissue damage according to various chemotherapeutic drugs and present an update on treatment and new antidotes including dexrazoxane for anthracyclines extravasation. We highlight the importance of education and training of the oncology team for prevention and prompt pharmacological and non-pharmacological management and stress the availability of new antidotes like dexrazoxane wherever anthracyclines are being infused.Firas Y Kreidieh Hiba A Moukadem Nagi S El Saghir 2016World Journal of Clinical Oncology2016,7,1:8
4Development of an Arabic version of the National Eye Institute Visual Function Questionnaire as a tool to study eye diseases patients in Egypt显示文摘AIM:To develop and test an Arabic version of the National Eye Institute Visual Function Questionnaire-25(NEI-VFQ-25).METHODS:NEI-VFQ-25 was translated into Arabic according to WHO translation guidelines. We enrolled adult consenting patients with bilateral chronic eye diseases who presented to 14 hospitals across Egypt from October to December 2012, and documented their clinical findings. Psychometric properties were then tested using STATA.RESULTS:We recruited 379 patients, whose mean age was(54.5±15)y. Of 46.2% were males, 227 had cataract,31 had glaucoma, 23 had retinal detachment, 37 had diabetic retinopathy, and 61 had miscellaneous visual defects. Non-response rate and the floor and ceiling numbers of the Arabic version(ARB-VFQ-25) were calculated. Internal consistency was high in all subscales(except general health), with Cronbach-α ranging from0.702-0.911. Test-retest reliability was high(intraclass correlation coefficient 0.79).CONCLUSION:RB-VFQ-25 isareliableandvalidtool for assessing visual functions of Arabic speaking patients. However, some questions had high non-response rates and should be substituted by available alternatives. Our results support the importance of including self-reported visual functions as part of routine ophthalmologic examination.Nizar Saleh Abdelfattah Mohamed Amgad Ahmed A Salama Marina E Israel Ghada A Elhawary Ahmed E Radwan Mohamed M Elgayar Tamer M EL Nakhal Islam T Elkhateb Heba A Hashem Doha K Embaby Amira A Elabd Reem K Elwy Magdi S Yacoub Hamdy Salem Mohamed Abdel-Baqy Ahmad Kassem 2014International Journal of Ophthalmology(English edition)2014,7,5:8
5Role of relevant immune-modulators and cytokines in hepatocellular carcinoma and premalignant hepatic lesions显示文摘AIM To assess the levels of different immune modulators in patients with hepatocellular carcinoma(HCC),in relation to other hepatic diseases.METHODS Eighty-eight patients were included in the current study and represented patients with HCC(20),liver cirrhosis(28) and chronic hepatitis(CH;25),and normal controls(NC;15).Peripheral blood was isolated for immunophenotyping of active myeloid dendritic cells(m DCs;CD1 c and CD40),mature inactive myeloid cells(CD1 c and HLA),active plasmacytoid cells(p DCs;CD303 and CD40),mature inactive p DCs(CD30 and HLA),active natural killer(NK) cells(CD56 and CD161),active NK cells(CD56 and CD314) and inactive NK cells(CD56 and CD158) was done by flow cytometry.Serum levels of interleukin(IL)-2,IL-10,IL-12,IL-1β,interferon(IFN)-α,IFN-γ and tumor necrosis factor(TNF)-αR2 were assessed by ELISA.RESULTS Active m DCs(CD1 C+/CD40+) and inactive m DCs(CD1 c+/HLA+) were significantly decreased in HCC patients in relation to NC(P < 0.001).CD40+ expression on active p DCs was decreased in HCC patients(P < 0.001),and its level was not significantly changed among other groups.Inactive p DCs(CD303+/HLA+),inactive NKs(CD56+/CD158+) and active NKs(CD56+/CD161+) were not statistically changed among the four groups studied;however,the latter was increased in CH(P < 0.05).NKG2 D was statistically decreased in HCC,CH and cirrhosis(P < 0.001),and it was not expressed in 63%(12/20) of HCC patients.There was significant decrease of IL-2,IFN-α and IFN-γ(P < 0.001),and a significant increase in IL-10,IL-1β,and TNF-αR2(P <0.01,P < 0.001 and P < 0.001;respectively) in HCC patients.There was inverted correlation between IL-12 and IL-1β in HCC(r =-0.565,P < 0.01),with a strong correlation between p DCs(CD303+/CD40+) and NKs(CD56+/CD161+;r = 0.512,P < 0.05) as well as inactive m DCs(CD1 c+/HLA+) and inactive NK cells(CD56+/CD158+;r = 0.945,P < 0.001).CONCLUSION NKG2 D,CD40,IL-2 and IL-10 are important modulators in the development and progression of HCC.Abdel-Rahman N Zekri Somaya El Deeb Abeer A Bahnassy Abeer M Badr Mona S Abdellateif Gamal Esmat Hosny Salama Marwa Mohanad Ahmed Esam El-dien Shimaa Rabah Assmaa Abd Elkader 2018World Journal of Gastroenterology2018,24,11:6
6Drainage vs. non-drainage after cholecystectomy for acute cholecystitis:a retrospective study显示文摘Many surgeons practice prophylactic drainage after cholecystectomy without reliable evidence,this study was conducted to answer the question whether to drain or not to drain after cholecystectomy for acute calculous cholecystitis.A retrospective review of all patients who had cholecystectomy for acute cholecystitis in Aseer Central Hospital,Abha,Saudi Arabia,was conducted from April 2010 to April 2012.Data were extracted from hospital case files.Preoperative data included clinical presentation,routine investigations and liver function tests.Operative data included excessive adhesions,bleeding,bile leak,and drain insertion.Complicated cases such as pericholecystic collections,mucocele and empyema were also reported.Patients who needed therapeutic drainage were excluded.Postoperative data included hospital stay,volume of drained fluid,time of drain removal,and drain site problems.The study included 103 patients allocated into two groups;group A(n = 38) for patients with operative drain insertion and group B(n = 65) for patients without drain insertion.The number of patients with preoperative diagnosis of acute non-complicated cholecystitis was significantly greater in group B(80%) than group A(36.8%)(P < 0.001).Operative time was significantly longer in group A.All patients who were converted from laparoscopic to open cholecystectomy were in group A.Multivariate analysis revealed that hospital stay was significantly(P < 0.001) longer in patients with preoperative complications.There was no added benefit for prophylactic drain insertion after cholecystectomy for acute calculous cholecystitis in non-complicated or in complicated cases.Mohammed A Bawahab Walid M Abd El Maksoud Saeed A Alsareii Fahad S Al Amri Hala F Ali Abdul Rahman Nimeri Abdul Rahman M Al Amri Adel A Assiri Mohammed I Abdul Aziz 2014The Journal of Biomedical Research2014,28,3:3
7Assessment of lnc RNA GAS5, lnc RNA HEIH, lnc RNA BISPR and its m RNA BST2 as serum innovative non-invasive biomarkers: Recent insights into Egyptian patients with hepatitis C virus type 4显示文摘BACKGROUND Hepatitis C virus(HCV)infection and its consequent complications are undeniably a public health burden worldwide,particularly in Egypt.Emerging evidence suggests that many lncRNAs have relevant roles in viral infections and antiviral responses.AIM To investigate the expression profiles of circulating lncRNAGAS5,lncRNAHEIH,lncRNABISPR and mRNABST2 in naïve,treated and relapsed HCV Egyptian patients,to elucidate relation to HCV infection and their efficacy as innovative biomarkers for the diagnosis and prognosis of HCV GT4.METHODS One hundred and thirty HCV-infected Egyptian patients and 20 healthy controls were included in this study.Serum lncRNAs and mRNABST2 were measured using quantitative real-time polymerase chain reaction(qRT-PCR).RESULTS Our results indicated that serum lncRNAGAS5 and LncRNABISPR were upregulated,whereas mRNA BST2 and LncRNA HEIH were downregulated in naïve patients.In contrast,HCV patients treated with sofosbuvir and simeprevir;with sofosbuvir and daclatasvir;or with sofosbuvir,daclatasvir and ribavirin exhibited lower levels of lncRNAGAS5 and lncRNABISPR with higher mRNABST2 compared to naïve patients.Notably,patients relapsed from sofosbuvir and simeprevir showed higher levels of these lncRNAs with lower mRNABST2 compared to treated patients.LncRNAGAS5 and lncRNABISPR were positively correlated with viral load and ALT at P<0.001,whereas mRNABST2 was negatively correlated with viral load at P<0.001 and ALT at P<0.05.Interestingly,a significant positive correlation between lncRNA HEIH and AFP was observed at P<0.001.CONCLUSION Differential expression of these RNAs suggests their involvement in HCV pathogenesis or antiviral response and highlights their promising roles in diagnosis and prognosis of HCV.Nourhan M El Samaloty Marwa I Shabayek Ramy S Ghait Shohda A El-Maraghy Sherine M Rizk Maha M El-Sawalhi 2020World Journal of Gastroenterology2020,26,2:2
8Coronary physiology assessment in the catheterization laboratory显示文摘Physicians cannot rely solely on the angiographic appearance of epicardial coronary artery stenosis when evaluating patients with myocardial ischemia. Instead, sound knowledge of coronary vascular physiology and of the methods currently available for its characterization can improve the diagnostic and prognostic accuracy of invasive assessment of the coronary circulation, and help improve clinical decision-making. In this article we summarize the current methods available for a thorough assessment of coronary physiology.Felipe Díez-delhoyo Enrique Gutiérrez-Ibanes Gerard Loughlin Ricardo Sanz-Ruiz María Eugenia Vázquez-álvarez Fernando Sarnago-Cebada Rocío Angulo-Llanos Ana Casado-Plasencia Jaime Elízaga Francisco Fernández Avilés Diáz 2015World Journal of Cardiology2015,7,9:2

12Software Project Management Approaches for Global Software Development: A Systematic Mapping Study显示文摘Global Software Development(GSD) is a well established field of software engineering with the benefits of a global environment. Software Project Management(SPM) plays a key role in the success of GSD. As a result, the need has arisen to study and evaluate the downsides of SPM for GSD, to thereby pave the way for the development of new methods, techniques, and tools with which to tackle them. This paper aims to identify and classify research on SPM approaches for GSD that are available in the literature, to identify their current weaknesses and strengths, and to analyze their applications in industry. We performed a Systematic Mapping Study(SMS) based on six classification criteria. Eighty-four papers were selected and analyzed. The results indicate that interest in SPM for GSD has been increasing since 2006. As a class of approaches, the most frequently reported methods(40%) are those used for coordination, planning, and monitoring, along with estimation techniques that can be used to better match a distributed project. SPM for GSD requires further investigation by researchers and practitioners, particularly with respect to cost and time estimations. These findings will help overcome the challenges that must to be considered in future SPM research for GSD, especially regarding collaboration and time-zone differences.Manal El Bajta Ali Idri Joaquín Nicolás Ros José Luis Fernández-Alemán Juan Manuel Carrillo de Gea Félix García Ambrosio Toval 2018Tsinghua Science and Technology2018,23,6:2
13Safety and efficacy of Hansenula-derived PEGylated-interferon alpha-2a and ribavirin combination in chronic hepatitis C Egyptian children显示文摘AIM:To investigate the safety and efficacy of a Hansenula-derived PEGylated(polyethylene glycol)interferon(IFN)-alpha-2a(Reiferon Retard)plus ribavirin customized regimen in treatment-na?ve and previously treated(non-responders and relapsers)Egyptian children with chronic hepatitis C infection.METHODS:Forty-six children with chronic hepatitis C virus(HCV)infection were selected from three tertiary pediatric hepatology centers.Clinical and laboratory evaluations were undertaken.Quantitative polymerase chain reaction(PCR)for HCV-RNA was performed before starting treatment,and again at 4,12,24,48,72wk during treatment and 6 mo after treatment cessation.All patients were assigned to receive a weekly subcutaneous injection of PEG-IFN-alpha-2a plus daily oral ribavirin for 12 wk.Thirty-four patients were treatment-na?ve and 12 had a previous treatment trial.Patients were then divided according to PCR results into two groups.GroupⅠincluded patients who continued treatment on a weekly basis(7-d schedule),while groupⅡincluded patients who continued treatment on a 5-d schedule.Patients from either group who were PCR-negative at week 48,but had at least one PCRpositive test during therapy,were assigned to have an extended treatment course up to 72 wk.The occurrence of adverse effects was assessed during treatment and follow up.The study was registered at www.ClinicalTrials.gov(NCT02027493).RESULTS:Only 11 out of 46(23.9%)patients showed a sustained virological response(SVR),two patients were responders at the end of treatment;however,they were lost to follow up at 6 mo post treatment.Breakthrough was seen in 18(39.1%)patients,one patient(2.17%)showed relapse and 14(30.4%)were non-responders.Male gender,short duration of infection,low viral load,mild activity,and mild fibrosis were the factors related to a better response.On the other hand,patients with high viral load and absence of fibrosis failed to respond to treatment.Before treatment,liver transaminases were elevated.After commencing treatment,they were normalized in all patients at week 4 and were maintained normal in responders till the end of treatment,while they increased again significantly in non-responders(P=0.007 and 0.003 at week 24 and 72 respectively).The 5-d schedule did not affect the response rate(1/17 had SVR).Treatment duration(whether 48 wk or extended course to 72 wk)gave similar response rates(9/36 vs 2/8 respectively;P=0.49).Type of previous treatment(short acting IFN vs PEG-IFN)did not affect the response to retreatment.On the other hand,SVR was significantly higher in previous relapsers than in previous non-responders(P=0.039).Only mild reversible adverse effects were observed and children tolerated the treatment well.CONCLUSION:Reiferon Retard plus ribavirin combined therapy was safe.Our customized regimen did not influence SVR rates.Further trials on larger numbers of patients are warranted.Suzan El Naghi Tawhida Y Abdel-Ghaffar Hanaa El-Karaksy Elham F Abdel-Aty Mona S El-Raziky Aleef A Allam Heba Helmy Hanaa A El-Araby Behairy E Behairy Mohamed A El-Guindi Hatem El-Sebaie Aisha Y Abdel-Ghaffar Nermin A Ehsan Ahmed M El-Hennawy Mostafa M Sira 2014World Journal of Gastroenterology2014,20,16:2
