2Middle East respiratory syndrome coronavirus disease is rare in children: An update from Saudi Arabia显示文摘AIM To summarize the reported Middle East respiratory syndrome-coronavirus(MERS-Co V) cases, the associated clinical presentations and the outcomes. METHODS We searched the Saudi Ministry of Health website, the World Health Organization website, and the Flutracker website. We also searched MEDLINE and Pub Med for the keywords: Middle East respiratory syndromecoronavirus, MERS-Co V in combination with pediatric, children, childhood, infancy and pregnancy from the initial discovery of the virus in 2012 to 2016. The retrieved articles were also read to further find other articles. Relevant data were placed into an excel sheet and analyzed accordingly. Descriptive analytic statistics were used in the final analysis as deemed necessary.RESULTS From June 2012 to April 19, 2016, there were a total of 31 pediatric MERS-Co V cases. Of these cases 13(42%) were asymptomatic and the male to female ratio was 1.7:1. The mean age of patients was 9.8 ± 5.4 years. Twenty-five(80.6%) of the cases were reported from the Kingdom of Saudi Arabia. The most common source of infection was household contact(10 of 15 with reported source) and 5 patients acquired infection within a health care facility. Using real time reverse transcriptase polymerase chain reaction of pediatric patients revealed that 9 out of 552(1.6%) was positive in the Kingdom of Saudi Arabia. CONCLUSION Utilizing serology for MERS-CoV infection in Jordan andSaudi Arabia did not reveal any positive patients. Thus, the number of the pediatric MERS-CoV is low; the exact reason for the low prevalence of the disease in children is not known.Jaffar A Al-Tawfiq Rana F Kattan Ziad A Memish 2016World Journal of Clinical Pediatrics2016,5,4:8
3Corneal biomechanical data and biometric parameters measured with Scheimpflug-based devices on normal corneas显示文摘AIM: To analyze the correlations between ocular biomechanical and biometric data of the eye,measured by Scheimpflug-based devices on healthy subjects.METHODS: Three consecutive measurements were carried out using the corneal visualization Scheimpflug technology(Cor Vis ST) device on healthy eyes and the 10 device-specific parameters were recorded.Pentacam HR-derived parameters(corneal curvature radii on the anterior and posterior surfaces;apical pachymetry;corneal volume;corneal aberration data;depth,volume and angle of the anterior chamber) and axial length(AL) from IOLMaster were correlated with the 10 specific CorV is ST parameters.RESULTS: Measurements were conducted in 43 eyes of 43 volunteers(age 61.24±15.72y).The 10 specific Cor Vis ST data showed significant relationships with corneal curvature radii both on the anterior and posterior surface,pachymetric data,root mean square(RMS) data of lower-order aberrations,and posterior RMS of higher-order aberrations and spherical aberration of the posterior cornea.Anterior chamber depth showed a significant relationship,but there were no significant correlations between corneal volume,anterior chamber volume,mean chamber angle or AL and the 10 specific CorV is ST parameters.CONCLUSION: Cor Vis ST-generated parameters are influenced by corneal curvature radii,some corneal RMS data,but corneal volume,anterior chamber volume,chamber angle and AL have no correlation with the biomechan-ical parameters.The parameters measured by CorV is ST seem to refer mostly to corneal properties of the eye.Gabor Nemeth Eszter Szalai Ziad Hassan Agnes Lipecz Zsuzsa Flasko Laszlo Modis 2017International Journal of Ophthalmology(English edition)2017,10,2:6
4Evaluation of IGL-1 preservation solution using an orthotopic liver transplantation model显示文摘AIM: To compare, in a pig liver transplantation model, the protective effect of UW with that of IGL-1, a high-sodium preservation solution containing polyethylene glycol (PEG) as an oncotic supply. METHODS: All livers were harvested and grafted orthotopically according to standard techniques. The livers were washed out and preserved for 7 h in IGL-1 (n = 6) or in UW solution (n = 7) at 4℃. In a sham group (n = 4), the livers underwent a 60-min warm ischemia at 37℃. The hepatocellular injury was assessed in organ preservation solution washed out from the graft at the end of ischemic storage (before revascularization), and in serum 2 h after reperfusion and daily for up to 6 d. RESULTS: Livers preserved in IGL-1 solution released markedly less AST than that preserved in the UW solution before and after revascularization (P < 0.05). Besides, the activity of creatine kinase-BB, a marker of sinusoidal lining cells injury, was higher in the UW group than in the IGL-1 group (P < 0.05). Histological results showed less necrotic regions in livers preserved in IGL-1 solution; however, no difference was observed for in? ammation. CONCLUSION: IGL-1 liquid effectively protects parenchymal and non-parenchymal cells against prese-rvation-reperfusion injuries.Hassen Ben Abdennebi Ziad Elrassi Jean-Yves Scoazec Jean-Paul Steghens Silvina Ramella-Virieux Olivier Boillot 2006World Journal of Gastroenterology2006,12,33:5
5Viral respiratory infections among Hajj pilgrims in 2013显示文摘Middle East respiratory syndrome coronavirus(MERS-Co V) has emerged in the Arabian Gulf region, with its epicentre in Saudi Arabia, the host of the ‘Hajj' which is the world's the largest mass gathering. Transmission of MERS-Co V at such an event could lead to its rapid worldwide dissemination. Therefore, we studied the frequency of viruses causing influenza-like illnesses(ILI) among participants in a randomised controlled trial at the Hajj 2013. We recruited 1038 pilgrims from Saudi Arabia, Australia and Qatar during the first day of Hajj and followed them closely for four days. A nasal swab was collected from each pilgrim who developed ILI. Respiratory viruses were detected using multiplex RT-PCR. ILI occurred in 112/1038(11%) pilgrims. Their mean age was 35 years, 49(44%) were male and 35(31%) had received the influenza vaccine pre-Hajj. Forty two(38%) pilgrims had laboratory-confirmed viral infections; 28(25%) rhinovirus, 5(4%) influenza A, 2(2%) adenovirus, 2(2%) human coronavirus OC43/229 E, 2(2%) parainfluenza virus 3, 1(1%) parainfluenza virus 1, and 2(2%) dual infections. No MERS-Co V was detected in any sample. Rhinovirus was the commonest cause of ILI among Hajj pilgrims in 2013. Infection control and appropriate vaccination are necessary to prevent transmission of respiratory viruses at Hajj and other mass gatherings.Osamah Barasheed Harunor Rashid Mohammad Alfelali Mohamed Tashani Mohammad Azeem Hamid Bokhary Nadeen Kalantan Jamil Samkari Leon Heron Jen Kok Janette Taylor Haitham El Bashir Ziad A.Memish Elizabeth Haworth Edward C.Holmes Dominic E Dwyer Atif Asghar Robert Booy 2014Virologica Sinica2014,29,6:3
6Comparative effectiveness of i-SCAN^(TM) and high-definition white light characterizing small colonic polyps显示文摘AIM:To evaluate accuracy of in vivo diagnosis of adenomatous vs non-adenomatous polyps using i-SCAN digital chromoendoscopy compared with high-definition white light.METHODS:This is a single-center comparative effectiveness pilot study.Polyps(n = 103) from 75 averagerisk adult outpatients undergoing screening or surveillance colonoscopy between December 1,2010 and April 1,2011 were evaluated by two participating endoscopists in an academic outpatient endoscopy center.Polyps were evaluated both with high-definition white light and with i-SCAN to make an in vivo prediction of adenomatous vs non-adenomatous pathology.We determined diagnostic characteristics of i-SCAN and highdefinition white light,including sensitivity,specificity,and accuracy,with regards to identifying adenomatous vs non-adenomatous polyps.Histopathologic diagnosis was the gold standard comparison.RESULTS:One hundred and three small polyps,detected from forty-three patients,were included in the analysis.The average size of the polyps evaluated in the analysis was 3.7 mm(SD 1.3 mm,range 2 mm to 8 mm).Formal histopathology revealed that 54/103(52.4%) were adenomas,26/103(25.2%) were hyperplastic,and 23/103(22.3%) were other diagnoses include 'lymphoid aggregates','non-specific colitis,' and 'no pathologic diagnosis.' Overall,the combined accuracy of endoscopists for predicting adenomas was identical between i-SCAN(71.8%,95%CI:62.1%-80.3%) and high-definition white light(71.8%,95%CI:62.1%-80.3%).However,the accuracy of each endoscopist differed substantially,where endoscopist A demonstrated 63.0% overall accuracy(95%CI:50.9%-74.0%) as compared with endoscopist B demonstrating 93.3% overall accuracy(95%CI:77.9%-99.2%),irrespective of imaging modality.Neither endoscopist demonstrated a significant learning effect with i-SCAN during the study.Though endoscopist A increased accuracy using i-SCAN from 59%(95%CI:42.1%-74.4%) in the first half to 67.6%(95%CI:49.5%-82.6%) in the second half,and endoscopist B decreased accuracy using i-SCAN from 100%(95%CI:80.5%-100.0%) in the first half to 84.6%(95%CI:54.6%-98.1%) in the second half,neither of these differences were statistically significant.CONCLUSION:i-SCAN and high-definition white light had similar efficacy predicting polyp histology.Endoscopist training likely plays a critical role in diagnostic test characteristics and deserves further study.Johanna L Chan Li Lin Michael Feiler Andrew I Wolf Diana M Cardona Ziad F Gellad 2012World Journal of Gastroenterology2012,18,41:3
7Middle East respiratory syndrome coronavirus in pediatrics: a report of seven cases from Saudi Arabia显示文摘Infection with Middle East respiratory syndrome coronavirus (MERS-CoV) emerged in 2012 as an important respiratory disease with high fatality rates of 40%—60%. Despite the increased number of cases over subsequent years, the number of pediatric cases remained low. A review of studies conducted from June 2012 to April 19, 2016 reported 31 pediatric MERS-CoV cases. In this paper, we present the clinical and laboratory features of seven patients with pediatric MERS. Five patients had no underlying medical illnesses, and three patients were asymptomatic. Of the seven cases, four (57%) patients sought medical advice within 1-7 days from the onset of symptoms. The three other patients (43%) were asymptomatic and were in contact with patients with confirmed diagnosis of MERS-CoV. The most common presenting symptoms were fever (57%), cough (14%), shortness of breath (14%), vomiting (28%), and diarrhea (28%). Two (28.6%) patients had platelet counts of < 150 ×10^9/L, and one patient had an underlying end-stage renal disease. The remaining patients presented with normal blood count, liver function, and urea and creatinine levels. The documented MERS-CoV Ct values were 32 38 for four of the seven cases. Two patients (28.6%) had abnormal chest radiographic findings of bilateral infiltration. One patient (14.3%) required ventilator support, and two patients (28.6%) required oxygen supplementation. All the seven patients were discharged without complications.Sarah H. Alfaraj Jaffar A. Al-Tawfiq Talal A. Altuwaijri Ziad A. Memish 2019Frontiers of Medicine2019,13,1:3
8Ability of bone graft substitutes to support the osteoprogenitor cells: An in-vitro study显示文摘AIM: To compare seven commercially available bone graft substitutes(BGS) in terms of these properties and without using any additional biological growth factors.METHODS: Porcine osteoprogenitor cells were loaded on seven commercially available BGS and allowed to proliferate for one week followed by osteogenic induction. Staining for live/dead cells as well as scanning electron microscopy(SEM) was carried out to determine viability and cellular binding. Further outcome measures included alkaline phosphatase(ALP) assays with normalisation for DNA content to quantify osteogenic potential. Negative and positive control experiments were carried out in parallel to validate the results.RESULTS: Live/dead and SEM imaging showed higher viability and attachment with β-tricalcium phosphate(β-TCP) than with other BGS(P < 0.05). The average ALP activity in nmol/mL(normalised value for DNA content in nmol/μg DNA) per sample was 657.58(132.03) for β-TCP, 36.22(unable to normalise) for calcium sulphate, 19.93(11.39) for the Hydroxyapatite/Tricalcium Phosphate composite, 14.79(18.53) for polygraft, 13.98(8.15) for the highly porous β-Tricalcium Phosphate, 5.56(10.0) for polymers, and 3.82(3.8) for Hydroxyapatite.CONCLUSION: Under the above experimental conditions, β-TCP was able to maintain better the viability of osteoprogenitor cells and allow proliferation and differentiation(P < 0.05).Ziad Dahabreh Michalis Panteli Ippokratis Pountos Mark Howard Peter Campbell Peter V Giannoudis 2014World Journal of Stem Cells2014,6,4:3
9Effect of acid etching on marginal adaptation of mineral trioxide aggregate to apical dentin:microcomputed tomography and scanning electron microscopy analysis显示文摘The present investigation assessed the effect of acid etching on marginal adaptation of white- and gray-colored mineral trioxide aggregate (MTA) to apical dentin using microcomputed tomography (micro-CT) and scanning electron microscopy (SEM). Sixty-four extracted single-rooted human maxillary teeth were used. Following root-end resection and apical preparation, the teeth were equally divided into four groups according to the following root end filling materials: (i) white-colored MTA (WMTA), (ii) etched WMTA (EWMTA), (iii) gray-colored MTA (GMTA) and (iv) etched GMTA (EGMTA). After 48 h, the interface between root-end filling materials and the dentinal walls was assessed using micro-CT and SEM. Data were statistically analyzed using the Kruskal-Wallis and Dunn tests. Micro-CT analysis revealed gap volumes between the apical cavity dentin walls and EGMTA, GMTA, EWMTA and WMTA of (0.007 160.004) mm 3 , (0.05360.002) mm 3 , (0.003 660.001) mm 3 and (0.005 960.002) mm 3 respectively. SEM analysis revealed gap sizes for EGMTA, WMTA, EWMTA and GMTA to be (492.3613.8) mm, (594.5617.12) mm, (543.1615.33) mm and (910.7626.2) mm respectively. A significant difference in gap size between root end preparations filled with GMTA and EGMTA was found (P,0.05). No significance difference in gap size between WMTA and EWMTA were found in either SEM or micro-CT analysis. In conclusion, pre-etching of apical dentin can provide a better seal for GMTA but not for WMTA.Khalid Al-Fouzan Ziad Al-Garawi Khalid Al-Hezaimi Fawad Javed Thakib Al-Shalan Ilan Rotstein 2012International Journal of Oral Science2012,4,4:3
10Is analysis of lower esophageal sphincter vector volumes of value in diagnosing gastroesophageal reflux disease?显示文摘AIM: With successful surgical treatment of gastroesophagealreflux disease (GERD), there is interest in understandingthe anti-reflux barrier and its mechanisms of failure. To date,the potential use of vector volumes to predict the DeMeesterscore has not been adequately explored.METHODS: 627 patients in the referral database receivedesophageal manometry and ambulatory 24-hour pHmonitoring. Study data included LES resting pressure (LESP),overall LES length (OL) and abdominal length (AL), totalvector volume (TW) and intrabdominal vector volume (IVV).RESULTS: In cases where LESP, TVV or IVV were all belownormal, there was an 81.4 % probability of a positiveDeMeester score. In cases where all three were normal,there was an 86.9 % probability that the DeMeester scorewould be negative. Receiver-operating characteristics (ROC)for LESP, TW and IW were nearly identical and indicatedno useful cut-off values. Logistic regression demonstratedthat LESP and IVV had the strongest association with apositive DeMeester score; however, the regression formulawas only 76.L % accurate.CONCLUSION: While the indices based on TVV, IW andLESP are more sensitive and specific, respectively, than anysingle measurement, the measurement of vector volumesdoes not add significantly to the diagnosis of GERD.Robert E.Marsh Christopher L.Perdue Ziad T.Awad Patrice Watson Mohamed Selima Richard E.Davis Charles J.Filipi 2003World Journal of Gastroenterology2003,9,1:3

13Exploring the role of molecular biomarkers as a potential weapon against gastric cancer: a review of the literature显示文摘Gastric cancer(GC) is a global health problem and a major cause of cancer-related death with high recurrence rates ranging from 25% to 40% for GC patients staging Ⅱ-Ⅳ. Unfortunately, while the majority of GC patients usually present with advanced tumor stage; there is still limited evidence-based therapeutic options. Current approach to GC management consists mainly of; endoscopy followed by, gastrectomy and chemotherapy or chemo-radiotherapy. Recent studies in GC have confirmed that it is a heterogeneous disease. Many molecular characterization studies have been performed in GC. Recent discoveries of the molecular pathways underlying the disease have opened the door to more personalized treatment and better predictable outcome. The identification of molecular markers is a useful tool for clinical managementin GC patients, assisting in diagnosis, evaluation of response to treatment and development of novel therapeutic modalities. While chemotherapeutic agents have certain physiological effects on the tumor cells, the prediction of the response is different from one type of tumor to the other. The specificity of molecular biomarkers is a principal feature driving their application in anticancer therapies. Here we are trying to focus on the role of molecular pathways of GC and well-established molecular markers that can guide the therapeutic management.Marwa Matboli Sarah El-Nakeep Nourhan Hossam Alaa Habieb Ahmed EM Azazy Ali E Ebrahim Ziad Nagy Omar Abdel-Rahman 2016World Journal of Gastroenterology2016,22,26:2
