| 2 | Guide for diagnosis and treatment of hepatocellular carcinoma显示文摘Hepatocellular carcinoma(HCC) is ranked as the 5th common type of cancer worldwide and is considered as the 3rd common reason for cancer-related deaths. HCC often occurs on top of a cirrhotic liver. The prognosisis determined by several factors; tumour extension, alpha-fetoprotein(AFP) concentration, histologic subtype of the tumour, degree of liver dysfunction, and the patient's performance status. HCC prognosis is strongly correlated with diagnostic delay. To date, no ideal screening modality has been developed. Analysis of recent studies showed that AFP assessment lacks adequate sensitivity and specificity for effective surveillance and diagnosis. Many tumour markers have been tested in clinical trials without progressing to routine use in clinical practice. Thus, surveillance is still based on ultrasound(US) examination every 6 mo. Imaging studies for diagnosis of HCC can fall into one of two main categories: routine non-invasive studies such as US, computed tomography(CT), and magnetic resonance imaging, and more specialized invasive techniques including CT during hepatic arteriography and CT arterial portography in addition to the conventional hepatic angiography. This article provides an overview and spotlight on the different diagnostic modalities and treatment options of HCC. | Magdy Hamed Attwa Shahira Aly El-Etreby | 2015 | World Journal of Hepatology2015,7,12: | 47 |
| 3 | Temporal trends in organophosphorus pesticides use and concentrations in river water in Japan, and risk assessment显示文摘We reviewed organophosphorus pesticide use in Japan between 1982 and 2016 using data from the National Institute of Environmental Studies. Organophosphorus pesticide concentrations in river water throughout Japan were taken from the literature, and risk assessments were performed for some organophosphorus pesticides based on risk quotients and hazard quotients. Assessments were performed for 20 common pesticides,including insecticides, fungicides, and herbicides. The amounts used decreased in the order: insecticides > herbicides > fungicides. Organophosphorus insecticide and fungicide use have decreased over the last four decades, but organophosphorus herbicide use has increased. During this period, annual organophosphorus pesticide use was the highest for chlorpyrifos(105,263 tons/year) and the lowest for glyphosate-sodium(8 tons/year). The ecotoxicological risk assessment indicated that diazinon and fenitrothion posed strong risks to the Japanese aquatic environment, and chlorpyrifos and malathion have moderate risks. None of the pesticides that were assessed posed significant risks to humans.Continued use of organophosphorus pesticides in Japan may cause strong risks to aquatic environments. These risks should be reassessed periodically. | Aly Derbalah Russel Chidya Waqar Jadoon Hiroshi Sakugawa | 2019 | Journal of Environmental Sciences2019,31,5: | 13 |
| 4 | Effect of alternative antibiotics in treatment of cefotaxime resistant spontaneous bacterial peritonitis显示文摘AIM:To evaluate effective alternative antibiotics in treatment of cefotaxime-resistant spontaneous bacterial peritonitis.METHODS:One hundred cirrhotic patients with spontaneous bacterial peritonitis [ascitic fluid polymorphonuclear cell count(PMNLs) ≥ 250 cells/mm 3 at admission] were empirically treated with cefotaxime sodium 2 g/12 h and volume expansion by intravenous human albumin.All patients were subjected to history taking,complete examination,laboratory tests(including a complete blood cell count,prothrombin time,biochemical tests of liver and kidney function,and fresh urine sediment),chest X-ray,a diagnostic abdominal paracentesis,and the sample subjected to total and differential cell count,chemical examination,aerobic and anaerobic cultures.Patients were divided after 2 d by a second ascitic PMNL count into group Ⅰ;patients sensitive to cefotaxime(n = 81),group Ⅱ(n = 19);cases resistant to cefotaxime(less than 25% decrease in ascitic PMNL count).Patients of group Ⅱ were randomly assigned into meropenem(n = 11) or levofloxacin(n = 8) subgroups.All patients performed an end of treatment ascitic PMNL count.Patients were considered improved when:PMNLs decreased to < 250 cells/mm 3,no growth in previously positive culture cases,and improved clinical manifestations with at least 5 d of antibiotic therapy.RESULTS:Age,sex,and Child classes showed no significant difference between group Ⅰ and group Ⅱ.Fever and abdominal pain were the most frequent manifestations and were reported in 82.7% and 80.2% of patients in group Ⅰ and in 94.7% and 84.2% of patients in group Ⅱ,respectively.Patients in group Ⅱ had a more severe ascitic inflammatory response than group Ⅰ and this was demonstrated by more ascitic lactate dehydrogenase(LDH) [median:540 IU/L(range:150-1200 IU/L) vs median:240 IU/L(range:180-500 IU/L),P = 0.000] and PMNL [median:15 000 cell/mm 3(range:957-23 822 cell/mm 3) vs 3400 cell/mm 3(range:695-26 400 cell/mm 3),P = 0.000] counts.Ascitic fluid culture was positive in 32% of cases.Cefotaxime failed in 19% of patients;of these patients,11(100%) responded to meropenem and 6(75%) responded to levofloxacin.Two patients with failed levofloxacin therapy were treated according to the in vitro culture and sensitivity(one case was treated with vancomycin and one case was treated with ampicillin/sulbactam).In group Ⅱ the meropenem subgroup had higher LDH(range:108-860 IU/L vs 120-491 IU/L,P = 0.042) and PMNL counts(range:957-23 822 cell/mm 3 vs 957-15 222 cell/mm 3,P = 0.000) at initiation of the alternative antibiotic therapy;there was no significant difference in the studied parameters between patients responsive to meropenem and patients responsive to levofloxacin at the end of therapy(mean ± SD:316.01 ± 104.03PMNLs/mm 3 vs 265.63 ± 69.61 PMNLs/mm 3,P = 0.307).The isolated organisms found in group Ⅱ were;enterococci,acinetobacter,expanded-spectrum β-lactamase producing Escherichia coli,β-lactamase producing Enterobacter and Staphylococcus aureus.CONCLUSION:Empirical treatment with cefotaxime is effective in 81% of cases;meropenem is effective in cefotaxime-resistant cases. | Ahmed Abouelkhair Badawy Tarik Ibrahim Zaher Samar Mahmoud Sharaf Mohamed Hassan Emara Noha Elsaid Shaheen Talaat Fathy Aly | 2013 | World Journal of Gastroenterology2013,19,8: | 13 |

| 16 | Further investigations to extract abundant new exact traveling wave solutions of some NLEEs显示文摘In this study,we implement the generalized(G/G)-expansion method established by Wang et al.to examine wave solutions to some nonlinear evolution equations.The method,known as the double(G/G,1/G)-expansion method is used to establish abundant new and further general exact wave solutions to the(3+1)-dimensional Jimbo-Miwa equation,the(3+1)-dimensional Kadomtsev-Petviashvili equation and symmetric regularized long wave equation.The solutions are extracted in terms of hyperbolic function,trigonometric function and rational function.The solitary wave solutions are constructed from the obtained traveling wave solutions if the parameters received some definite values.Graphs of the solutions are also depicted to describe the phenomena apparently and the shapes of the obtained solutions are singular periodic,anti-kink,singular soliton,singular anti-bell shape,compaction etc.This method is straightforward,compact and reliable and gives huge new closed form traveling wave solutions of nonlinear evolution equations in ocean engineering. | M.Mamun Miah Aly R.Seadawy H.M.Shahadat Ali M.Ali Akbar | 2019 | Journal of Ocean Engineering and Science2019,4,4: | 3 |
| 17 | Hepatocellular injury and the mortality risk among patients with COVID-19: A retrospective cohort study显示文摘BACKGROUND Clearly,infection with severe acute respiratory syndrome coronavirus 2 is not limited to the lung but also affects other organs.We need predictive models to determine patients’prognoses and to improve health care resource allocation during the coronavirus disease 2019(COVID-19)pandemic.While treating COVID-19,we observed differential outcome prediction weights for markers of hepatocellular injury among hospitalized patients.AIM To investigate the association between hepatocellular injury and all-cause inhospital mortality among patients with COVID-19.METHODS This multicentre study employed a retrospective cohort design.All adult patients admitted to Al-Azhar University Hospital,Assiut,Egypt and Abo Teeg General Hospital,Assiut,Egypt with confirmed COVID-19 from June 1,2020,to July 30,2020 were eligible.We categorized our cohort into three groups of(1)patients with COVID-19 presenting normal aminotransferase levels;(2)patients with COVID-19 presenting one-fold higher aminotransferase levels;and(3)patients with COVID-19 presenting two-fold higher aminotransferase levels.We analysed the association between elevated aminotransferase levels and all-cause in-hospital mortality.The survival analysis was performed using the Kaplan–Meier method and tested by log-rank analysis.RESULTS In total,376 of 419 patients met the inclusion criteria,while 29(8%)patients in our cohort died during the hospital stay.The median age was 40 years(range:28-56 years),and 51%were males(n=194).At admission,54%of the study cohort had liver injury.The pattern of liver injury was hepatocellular injury with an aspartate aminotransferase(AST)predominance.Admission AST levels were independently associated with all-cause in-hospital mortality in the logistic regression analysis.A one-fold increase in serum AST levels among patients with COVID-19 led to an eleven-fold increase in in-hospital mortality(P<0.001).Admission AST levels correlated with C-reactive protein(r=0.2;P<0.003)and serum ferritin(r=0.2;P<0.0002)levels.Admission alanine aminotransferase levels correlated with serum ferritin levels(r=0.1;P<0.04).Serum total bilirubin levels were independently associated with in-hospital mortality in the binary logistic regression analysis after adjusting for age and sex but lost its statistical significance in the fully adjusted model.Serum ferritin levels were significantly associated with in-hospital mortality(P<0.01).The probability of survival was significantly different between the AST groups and showed the following order:a two-fold increase in AST levels>a one-fold increase in in AST levels>normal AST levels(P<0.0001).CONCLUSION Liver injury with an AST-dominant pattern predicts the severity of COVID-19.Elevated serum ferritin levels are associated with fatal outcomes. | Ali Madian Ahmed Eliwa Hytham Abdalla Haitham A Azeem Aly | 2021 | World Journal of Hepatology2021,13,8: | 3 |
| 18 | Endoscopic management of Dieulafoy's lesion using Isoamyl-2-cyanoacrylate显示文摘Dieulafoy's lesion (DL) is a rare but important cause of obscure gastrointestinal bleeding that may be over-looked during diagnostic endoscopy. Mortality rates are similar to those of other causes for gastrointestinal bleeding. Diagnosis by upper endoscopy is the modal-ity of choice during acute bleeding. In the absence of active bleeding, the lesion resembles a raised nipple or visible vessel. There are no guidelines regarding effective selective therapy for DL, when diagnosed, en-doscopist experience is the major determinant of the treatment strategy. Following our strategy, an expert endoscopist with a skilled assistant should have a high rate of successful DL diagnosis when an obscured gas-trointestinal lesion is suspected. Cyanoacryltes com-pounds have been used successfully in management of Gastric varices and DLs. To our knowledge, there have been no previous reports regarding use of isoamyl-2-cyanoacrylate (AMCRYLATE ; Concord Drugs Ltd.,Hyderabad, India) as an effective therapy for gastric DL without serious complications. In our case study, Isoamyl-2-cyanoacrylate (AMCRYLATE) was effective and safe for treating DL. Surgical wedge resection of the lesion should be considered as a therapeutic option if endoscopic therapy fails. | Abd Elrazek M Aly Abd Elrazek Nakamura Yoko Moriguchi Hiroki Mohamed Afify Mohamed Asar Badr Ismael Magdy Salah | 2013 | World Journal of Gastrointestinal Endoscopy2013,5,8: | 3 |
| 19 | Transpressive Structures in the Ghadir Shear Belt, Eastern Desert, Egypt: Evidence for Partitioning of Oblique Convergence in the Arabian-Nubian Shield during Gondwana Agglutination显示文摘Transpressional deformation has played an important role in the late Neoproterozoic evolution of the ArabianNubian Shield including the Central Eastern Desert of Egypt.The Ghadir Shear Belt is a 35 km-long,NW-oriented brittleductile shear zone that underwent overall sinistral transpression during the Late Neoproterozoic.Within this shear belt,strain is highly partitioned into shortening,oblique,extensional and strike-slip structures at multiple scales.Moreover,strain partitioning is heterogeneous along-strike giving rise to three distinct structural domains.In the East Ghadir and Ambaut shear belts,the strain is pure-shear dominated whereas the narrow sectors parallel to the shear walls in the West Ghadir Shear Zone are simple-shear dominated.These domains are comparable to splay-dominated and thrust-dominated strike-slip shear zones.The kinematic transition along the Ghadir shear belt is consistent with separate strike-slip and thrustsense shear zones.The earlier fabric(S1),is locally recognized in low strain areas and SW-ward thrusts.S2 is associated with a shallowly plunging stretching lineation(L2),and defines^NW-SE major upright macroscopic folds in the East Ghadir shear belt.F2 folds are superimposed by^NNW–SSE tight-minor and major F3 folds that are kinematically compatible with sinistral transpressional deformation along the West Ghadir Shear Zone and may represent strain partitioning during deformation.F2 and F3 folds are superimposed by ENE–WSW gentle F4 folds in the Ambaut shear belt.The sub-parallelism of F3 and F4 fold axes with the shear zones may have resulted from strain partitioning associated with simple shear deformation along narrow mylonite zones and pure shear-dominant deformation in fold zones.Dextral ENEstriking shear zones were subsequently active at ca.595 Ma,coeval with sinistral shearing along NW-to NNW-striking shear zones.The occurrence of upright folds and folds with vertical axes suggests that transpression plays a significant role in the tectonic evolution of the Ghadir shear belt.Oblique convergence may have been provoked by the buckling of the Hafafit gneiss-cored domes and relative rotations between its segments.Upright folds,fold with vertical axes and sinistral strike-slip shear zones developed in response to strain partitioning.The West Ghadir Shear Zone contains thrusts and strikeslip shear zones that resulted from lateral escape tectonics associated with lateral imbrication and transpression in response to oblique squeezing of the Arabian-Nubian Shield during agglutination of East and West Gondwana. | Mohamed ABD EL-WAHED Samir KAMH Mahmoud ASHMAWY Aly SHEBL | 2019 | Acta Geologica Sinica(English Edition)2019,93,6: | 3 |
| 20 | Enhancement in antinociceptive and anti-inflammatory effects of tramadol by transdermal proniosome gel显示文摘Oral therapy of tramadol,an opiate analgesic,undergoes extensive hepatic metabolism and requires frequent administration.Transdermal therapy by virtue can overcome these issues and can improve the efficacy and reduce abuse liability of tramadol.The aim of this research was to investigate the possibility of transdermal delivery of tramadol by formulating proniosome gel and evaluate its therapeutic potential in vivo.The effect of formulation composition as well as amount of drug on physicochemical characteristics of prepared proniosomes were examined.Best proniosome gel(F4)was selected and evaluated for drug release,stability and transdermal efficacy by ex vivo and in vivo experiments.The vesicles demonstrated optimal properties including spherical shape,nanosize with good entrapment efficiency,adequate zeta potential,higher stability and greater transdermal flux.The amorphization and dispersion of tramadol in the aqueous core of proniosome vesicles was confirmed by differential scanning calorimeter.Release profile of F4 was distinct(P<0.001)from control and displayed steady and prolonged tramadol release by Fickian diffusion.Transdermal therapy of F4 showed prominent reduction of induced twitches(P<0.005)in mice and edema(P<0.05)in rats,as compared to oral tramadol.The improvement in clinical efficacy of tramadol in transdermal therapy is correlated with the pharmacokinetic data observed.In conclusion,the observed improvement in antinociceptive and anti-inflammatory effects from proniosome carriers signifies its potential to be a suitable alternative to oral therapy of tramadol with greater efficacy. | Jigar Shah Anroop B.Nair Hiral Shah Shery Jacob Tamer M.Shehata Mohamed Aly Morsy | 2020 | Asian Journal of Pharmaceutical Sciences2020,15,6: | 3 |
