1Efficacy and safety of tenofovir disoproxil fumarate in pregnancy for the prevention of vertical transmission of HBV infection显示文摘AIM:To evaluate the effects of tenofovir disoproxil fumarate(TDF)use during late pregnancy to reduce hepatitis B virus(HBV)transmission in highly viremic mothers.METHODS:This retrospective study included 45 pregnant patients with hepatitis B e antigen(+)chronic hepatitis B and HBV DNA levels>107copies/mL who received TDF 300 mg/d from week 18 to 27 of gestation(n=21).Untreated pregnant patients served as controls(n =24).All infants received 200 IU of hepatitis B immune globulin(HBIG)within 24 h postpartum and 20μg of recombinant HBV vaccine at 4,8,and 24 wk.Perinatal transmission rate was determined by hepatitis B surface antigen and HBV DNA results in infants at week 28.RESULTS:At week 28,none of the infants of TDFtreated mothers had immunoprophylaxis failure,whereas2(8.3%)of the infants of control mothers had immunoprophylaxis failure(P=0.022).There were no differences between the groups in terms of adverse events in mothers or congenital deformities,gestational age,height,or weight in infants.At postpartum week 28,significantly more TDF-treated mothers had levels of HBV DNA<250 copies/mL and normalized alanine aminotransferase compared with controls(62%vs none,P<0.001;82%vs 61%,P=0.012,respectively).CONCLUSION:TDF therapy during the second or third trimester reduced perinatal transmission rates of HBV and no adverse events were observed in mothers or infants.Mustafa Kemal Celen Duygu Mert Müzeyyen Ay Tuba Dal Safak Kaya Necmettin Yildirim Serda Gulsun Tunga Barcin Sevgi Kalkanli Mehmet Sinan Dal Celal Ayaz 2013World Journal of Gastroenterology2013,19,48:26
2Role of triamcinolone in radiation enteritis management显示文摘AIM:To investigate the role of triamcinolone in the management of acute and chronic enteritis caused by pelvic radiotherapy.METHODS:Twenty-eight patients with rectum adenocarcinoma or endometrium adenocarcinoma were studied.We compared the results of 14 patients treated with injected triamcinolone acetonide(TA)with those of 14 patients who were not treated with TA.For the TA group,40 mg of TA was injected intramuscularly on the 1st,11th and 21st d of radiotherapy;the control group received no injections.All of the study participants had a median age of 65 years,had undergone postoperative radiotherapy and were evaluated weekly using Radiation Therapy Oncology Group and the European Organization for Research and Treatment of Cancer Acute Morbidity Score Criteria,and complete blood counts for every 10 d.RESULTS:Triamcinolone was found to effectively prevent and treat radiation-induced acute gastrointestinal(enteritis)and genitourinary(cystitis)side effects(P=0.022 and P=0.023).For the lower GI side effect follow up,11 patients in the control group had Grade 2toxicity and 3 patients had Grade 1 toxicity.In the TA group,5 patients had Grade 2 toxicity and 9 patients had Grade 1 toxicity.For the genitourinary system side effect follow up,4 patients had Grade 2 toxicity and 6patients had Grade 1 toxicity.Additionally,2 patients had Grade 2 toxicity and 2 patients had Grade 1 toxicity.The neutrophil counts did not differ between the TA group and the control group.There was no meaningful difference between age groups and primary cancers.At the 12th mo of follow up,there were no differences between groups for chronic side effects.CONCLUSION:Triamcinolone is a moderately potent steroid,that is inexpensive and has a good safety profile.It would be beneficial for reducing medical expenses related to treatment of radiation induced enteritis.Eren Cetin Aysen Sevgi Ozturk Haluk Orhun Sukran Ulger 2014World Journal of Gastroenterology2014,20,15:12
3Atherosclerosis and the role of immune cells显示文摘Atherosclerosis is a chronic inflammatory disease arising from lipids, specifically low-density lipoproteins, and leukocytes. Following the activation of endothelium with the expression of adhesion molecules and monocytes, inflammatory cytokines from macrophages, and plasmacytoid dendritic cells, high levels of interferon(IFN)-α and β are generated upon the activation of tolllike receptor-9, and T-cells, especially the ones with Th1 profile, produce pro-inflammatory mediators such as IFN-γ and upregulate macrophages to adhere to the endothelium and migrate into the intima. This review presents an exhaustive account for the role of immunecells in the atherosclerosis.Fulya Ilhan Sevgi Tas Kalkanli 2015World Journal of Clinical Cases2015,3,4:10
4Functional roles and clinical values of insulin-like growth factor-binding protein-5 in different types of cancers显示文摘Insulin-like growth factor-bindin g proteins (IGFBPs) are critical regulators of the mitogenic activity of insulin-like growth factors (IGFs). IGFBP5, one of these IGFBPs, has special structural features, including a nuclear transport domain, heparin-binding motif, and IGF/extracellular matrix/acid-labile subunit-binding sites. Furthermore, IGFBP5 has several functional effects on carcinogenesis and even normal cell processes, such as cell growth, death, motility, and tissue remodeling. These biological effects are sometimes related with IGF (IGF-dependent effects) and sometimes not (IGF-independent effects). The functional role of IGFBP5 is most likely determined in a cell-type and tissue-type specific manner but also depends on cell context, especially in terms of the diversity of interacting proteins and the potential for nuclear localization. Clinical findings show that IGFBP5 has the potential to be a useful clinical biomarker for predicting response to therapy and clinical outcome of cancer patients. In this review, we summarize the functional diversity and clinical importance of IGFBP5 in different types of cancers.Gökçe Güllü Sevgi Karabulut Mustafa Akkiprik 2012Chinese Journal of Cancer2012,31,6:8
5Survival in gastric cancer in relation to postoperative adjuvant therapy and determinants显示文摘AIM: To evaluate survival data in patients with gastric cancer in relation to postoperative adjuvant therapy and survival determinantsMETHODS: A total of 201 patients(mean ± SD age: 56.0 ± 11.9 years, 69.7% were males) with gastric carcinoma who were operated and followed up at Lutfi Kirdar Kartal Training and Research Hospital between 1998 and 2010 were included in this retrospective study. Follow up was evaluated divided into two consecutive periods(before 2008 and 2008-2010, respectively) based on introduction of 3-D conformal technique in radiotherapy at our clinic in 2008. Data on patient demographics, clinical and histopathological characteristics of gastric carcinoma and the type of treatment applied after surgery [postoperative adjuvant treatment protocols including chemoradiotherapy(CRT) and chemotherapy(CT), supportive therapy or follow up without any treatment] were recorded. The median duration and determinants of local recurrence free(LRF) survival, distant metastasis free(DMF) survival and overall survival were evaluated in the overall population as well as with respect to follow up years [1998-2008(n = 127) vs 2008-2010(n = 74)].RESULTS: Median duration for LRF survival, DMF survival and overall survival were 31.9, 24.1 and 31.9 mo, respectively in patients with postoperative adjuvant CRT. No significant difference was noted in median duration for LRF survival, DMF survival and overall survival with respect to treatment protocols in the overall population and also with respect to followed up periods. In the overall population, CT protocols FUFA [5-fluorouracil(400 mg/m2) and leucovorin-folinic acid(FA, 20 mg/m2)](29.9 mo) and UFT + Antre [a fixed combination of the oral FU prodrug tegafur(flouroprymidine, FT, 300 mg/m2 per day) with FA(Antrex?), 15 mg tablet, two times a day](42.5 mo) was significantly associated with longer LRF survival times than other CT protocols(P = 0.036), while no difference was noted between CT protocols in terms of DMF survival and overall survival. Among patients received CRT, overall survival was significantly longer in patients with negative than positive surgical margin(27.7 mo vs 22.4 mo, P = 0.016) in the overallstudy population, while time of radiotherapy initiation had no significant impact on survival times. Nodal stage was determined to be independent predictor of LRF survival in the overall study population with 4.959 fold(P = 0.042) increase in mortality in patients with nodal stage N2 compared to patients with nodal stage N0, and independent predictor of overall survival with 5.132 fold(P = 0.006), 5.263 fold(P = 0.027) and 4.056 fold(P = 0.009) increase in the mortality in patients with nodal stage N3a(before 2008), N3b(before 2008) and N2(overall study population) when compared to patients with N0 stage, respectively.CONCLUSION: Our findings emphasize the likelihood of postoperative adjuvant CRT to have a survival benefit in patients with resectable gastric carcinoma.Sevgi Ozden Zerrin Ozgen Hazan Ozyurt Cengiz Gemici Gokhan Yaprak Huseyin Tepetam Alpaslan Mayadagli 2015World Journal of Gastroenterology2015,21,4:7
6Thrombospondin-1 expression correlates with angiogenesis in experimental cirrhosis显示文摘AIM:To investigate the significance of Thrombospondin-1 (TSP-1) expression and its relationship with angiogenesis during experimental fibrosis. METHODS:Cirrhosis was induced in male Wistar rats by intraperitoneal administration of diethyl nitrosamine (DEN). The serial sections from liver tissues were stained with anti-CD34 and anti-TSP-1 antibodies before being quantitated by light microscopy. RESULTS:Our results showed that of TSP-1 expression gradually increases according to the severity of fibrosis (GroupⅠvs group Ⅱ, Group Ⅲ and Group Ⅳ;Group Ⅱ vs group Ⅲ and group Ⅳ;group Ⅲ vs group Ⅳ, P < 0.05). Moreover, TSP-1 expression was found to be correlated with angiogenesis (P < 0.05). CONCLUSION:The correlative evidence of the link between TSP-1 and fibrosis or angiogenesis provided by this study suggests that besides its role as a strong promoter of transforming growth factor-β1 (TGF-β1), TSP-1 might have an additional role in liver fibrogenesis by stimulating angiogenesis and this protein could be a potential target to prevent fibrogenesis in chronic inflammatory diseases of the liver.Gülsüm zlem Elpek Güzide Ayse Gkhan Sevgi Bozova 2008World Journal of Gastroenterology2008,14,14:7
7Prognostic role of sensitive-to-apoptosis gene expression in rectal cancer显示文摘AIM:To investigate the association between prognosis of rectal cancer treated with chemoradiotherapy(CRT) and expression of sensitive-to-apoptosis(SAG),B-cell lymphoma-extra large(Bcl-X L) and Bcl-2 homologous antagonist/killer(Bak).METHODS:Real-time quantitative polymerase chain reaction was used to determine the expression of proteins of interest,namely SAG,Bcl-X L,Bak and β-actin,in rectal carcinoma patients who had a follow-up period of 3 years after CRT.Biopsy specimens were excised from the rectal tumor preceding CRT.RESULTS:SAG,Bcl-X L and Bak proteins showed significant correlations with each other.In multivariate analysis,patients with high vs low SAG expression showed a statistically significant difference in 2-year survival rates:56% vs 73%,respectively(P = 0.056).On the other hand,there were no significant correlations between the expression levels of all three genes and metastatic rates or tumor responses to CRT.Mean overall survival in the patients with elevated SAG expression was 27.1 mo ± 3.9 mo [95% confidence interval(CI):19.3-34.9],and in patients with reduced expression,it was 32.1 mo ± 2.5 mo(95% CI:27.3-36.9).The corresponding values for Bcl-X L were 28.0 mo ± 4.1 mo(95% CI:19.9-36.1) and 31.7 mo ± 2.9 mo(95% CI:26.0-37.5),and those for Bak were 29.8 mo ± 3.7 mo(95% CI:22.5-37.2) and 30.6 mo ± 2.4 mo(95% CI:25.5-35.0),respectively.CONCLUSION:Two-year survival rates significantly correlated with low SAG expression,and SAG may be a candidate gene for good prognosis,independent of therapeutic response of different individuals.Sevgi A Ozden Hazan Ozyurt Zerrin Ozgen Olca Kilinc Mustafa Oncel Aylin E Gul Nimet Karadayi Nedime Serakinci Beki Kan Oya Orun 2011World Journal of Gastroenterology2011,17,44:6
8Late in-the-bag spontaneous IOL dislocation: risk factors and surgical outcomes显示文摘AIM: To evaluate the possible predisposing risk factors for late in-the-bag spontaneous IOL dislocations and to study the early surgical and visual outcomes of repositioning and exchange surgeries.METHODS: Medical and surgical records of 39 eyes of 39 patients who underwent IOL repositioning or exchange surgery for dislocation between 2010 and 2018 were reviewed. Possible predisposing risk factors and some characteristics of late in-the-bag spontaneous IOL dislocations;outcomes of IOL repositioning and exchange surgeries, including visual acuity, refractive status before and after surgery and postoperative complications were evaluated.RESULTS: The predisposing factors for late in-the-bag spontaneous IOL dislocations were pseudoexfoliation [PEX;12/39(30.8%)], previous vitreoretinal surgery [7/39(17.9%)], axial myopia [3/39(7.7%)], both PEX and axial myopia [1/39(2.6%)], both previous vitreoretinal surgery and axial myopia [2/39(5.1%)] and uveitis (1/39(2.6%))The mean interval between cataract and dislocation surgery was 7.23 y, greater in PEX positive group(8.63 y). The mean best corrected visual acuity(BCVA) improved significantly after dislocation surgery(P<0.001) and also improved significantly after exchange surgery(P=0.001). The mean value of spherical equivalant decreased significantly after dislocation surgery(P=0.011), whereas corneal astigmatism increased but this difference was not significant after dislocation surgery and exchange surgery(P=0.191, P=0.074, respectively).CONCLUSION: The most prevelant risk factors for late inthe-bag spontaneous IOL dislocations are PEX, previous vitreoretinal surgery and axial myopia. In the management of IOL dislocations, exchange surgery with small corneal incision seemed effective with improved BCVA and safety with low postoperative complications.Sevgi Subasi Nursen Yuksel V.Levent Karabas Busra Yilmaz Tugan 2019International Journal of Ophthalmology(English edition)2019,12,6:2
9An unusual cause of cholecystitis:Heterotopic pancreatic tissue in the gallbladder显示文摘Gallbladder localization of heterotopic pancreas (HP) is uncommon and very rarely gives rise to symptoms. Herein we report a case of HP found in the gallbladder neck presented with signs and symptoms of cholecystitis. The patient was a 40-year old male, suffering from epigastric pain, abdominal fullness and fever. On physical examination, the right upper abdomen was tender with a positive Murphy’s sign. Ultrasonographic examination showed a hydropic gallbladder without stones and he underwent a cholecystectomy. Pathological examination revealed an intramural nodule (9 mm) in the neck region which is consisted of acini, ducts and islet cells of an aberrant pancreatic tissue. Although HP is encountered rarely in the gallbladder and is found incidentally during pathological studies, this case emphasizes that HP might cause symptoms and present clinically as cholecystitis. For this reason, in patients presenting with symptomatic gallbladder diseases, including cholecystitis without any other pathology, HP should be taken into consideration before it is diagnosed as 'idiopathic’’.Glsm zlem Elpek Sevgi Bozova Gkben Y■d■r■m Kpesiz Mehmet ■■ 2007World Journal of Gastroenterology2007,13,2:2
10In Silico Screening of Natural Products as Potential Inhibitors of SARS-CoV-2 Using Molecular Docking Simulation显示文摘Objective:To explore potential natural products against severe acute respiratory syndrome coronavirus(SARS-CoV-2)via the study of structural and non-structural proteins of human coronaviruses.Methods:In this study,we performed an in-silico survey of 25 potential natural compounds acting against SARS-CoV-2.Molecular docking studies were carried out using compounds against 3-chymotrypsin-like protease(3 CL^(PHO)),papain-like protease(PL^(PRO)),RNA-dependent RNA polymerase(RdRp),non-structural protein(nsp),human angiotensin converting enzyme 2 receptor(hACE2 R),sapike glycoprotein(S protein),abelson murine leukemia viral oncogene homolog 1(ABL1),calcineurin-nuclear factor of activated T-cells(NFAT)and transmembrane protease serine 2.Results:Among the screened compounds,amentoflavone showed the best binding affinity with the 3 CL^(PRO),RdRp,nsp13,nsp15,hACE2 R,ABL1 and calcineurin-NFAT;berbamine with hACE2 R and ABL1;cepharanthine with nsp10,nsp14,nsp16,S protein and ABL1;glucogallin with nsp15;and papyriflavonol A with PL^(PRO)protein.Other good interacting compounds were juglanin,betulinic acid,betulonic acid,broussooflavan A,tomentin A,B and E,7-methoxycryptopleurine,aloe emodin,quercetin,tanshinone I,tylophorine and furruginol,which also showed excellent binding affinity towards a number of target proteins.Most of these compounds showed better binding affinities towards the target proteins than the standard drugs used in this study.Conclusion:Natural products or their derivatives may be one of the potential targets to fight against SARS-CoV-2.Rajib Hossain Chandan Sarkar Shardar Mohammad Hafiz Hassan Rasel Ahmed Khan Mohammad Arman Pranta Ray Muhammad Torequl Islam Sevgi Durna Dastan Javad Sharifi-Rad Zainab M.
