1New perspectives in the treatment of advanced or metastatic gastric cancer显示文摘Metastatic gastric cancer remains an incurable disease,with a relative 5-year survival rate of 7%-27%.Chemotherapy,which improves overall survival(OS) and quality of life,is the main treatment option.Metaanalysis has demonstrated that the best survival results obtained in earlier randomized studies were achieved with three-drug regimens containing a fluoropyrimidine,an anthracycline,and cisplatin(ECF).Although there has been little progress in improving median OS times beyond the 9-mo plateau achievable with the standard regimens,the availability of newer agents has provided some measure of optimism.A number of new combinations incorporating docetaxel,oxaliplatin,capecitabine,and S-1 have been explored in randomized trials.Some combinations,such as epirubicin-oxaliplatin-capecitabine,have been shown to be as effective as(or perhaps more effective than) ECF,and promising early data have been derived for S-1 in combination with cisplatin.One factor that might contribute to extending median OS is the advancement whenever possible to second-line cytotoxic treatments.However,the biggest hope for signif icant survival advances in the near future would be the combination of new targeted biological agents with existing chemotherapy f irst-line regimens.Gerardo Rosati Domenica Ferrara Luigi Manzione 2009World Journal of Gastroenterology2009,15,22:41
2Long-term alpha interferon and lamivudine combination therapy in non-responder patients with anti-HBe-positive chronic hepatitis B:Results of an open,controlled trial显示文摘AIM: To investigate the safety and efficacy of long-term combination therapy with alpha interferon and lamivudine in non-responsive patients with anti-HBe-positive chronic hepatitis B.METHODS: 34 patients received combination treatment (1 month lamivudine, 12 month lamivudine+interferon, 6month lamivudine), 24 received lamivudine (12 months),24 received interferon (12 months). Interferon was administered at 6 MU tiw and lamivudine at 100 mg orally once daily. Patients were followed up for 6 months after treatment.RESULTS: At the end of treatment, HBV DNA negativity rates were 88 % with lamivudine+interferon, 99 % with lamivudine and 55 % with interferon, (P=0.004, combination therapy vs. interferon, and P=0.001 lamivudine vs.interferon), and serum transaminase normalization rates were 84 %, 91% and 53 % (P=0.01 combination therapy vs. interferon, and P=0.012 lamivudine vs. interferon). Six months later, HBV DNA negativity rates were 44 % with lamivudine+interferon, 33 % with lamivudine and 25 % with interferon, and serum transaminase normalization rates were 61%, 42 % and 45 %, respectively, without statistical significance. No YMDD variants were observed with lamivudine+interferon (vs. 12 % with lamivudine). The combination therapy appeared to be safe. CONCLUSION: Although viral clearance and transaminase normalization are slower with long-term lamivudine+interferon than that with lamivudine alone, the combination regimen seems to provide more lasting benefits and to protect against the appearance of YMDD variants. Studies with other regimens regarding sequence and duration are needed.M.

3Alternate Wetting and Drying of Rice Reduced CH4 Emissions but Triggered N2O Peaks in a Clayey Soil of Central Italy显示文摘Reducing CH_4 and N_2O emissions from rice cropping systems while sustaining production levels with less water requires a better understanding of the key processes involved. Alternate wetting and drying(AWD) irrigation is one promising practice that has been shown to reduce CH_4 emissions. However, little is known about the impact of this practice on N_2O emissions, in particular under Mediterranean climate. To close this knowledge gap, we assessed how AWD influenced grain yield, fluxes and annual budgets of CH_4 and N_2O emissions, and global warming potential(GWP) in Italian rice systems over a 2-year period. Overall, a larger GWP was observed under AWD, as a result of high N_2O emissions which offset reductions in CH_4 emissions. In the first year, with 70% water reduction, the yields were reduced by 33%, CH_4 emissions decreased by 97%, while N_2O emissions increased by more than 5-fold under AWD as compared to PF; in the second year, with a 40% water saving, the reductions of rice yields and CH_4 emissions(13% and11%, respectively) were not significant, but N_2O fluxes more than doubled. The transition from anaerobic to aerobic soil conditions resulted in the highest N_2O fluxes under AWD. The duration of flooding, transition to aerobic conditions, water level above the soil surface, and the relative timing between fertilization and flooding were the main drivers affecting greenhouse gas mitigation potential under AWD and should be carefully planned through site-specific management options.Alessandra LAGOMARSINO Alessandro Elio AGNELLI Bruce LINQUIST Maria Arlene ADVIENTO-BORBE Alberto AGNELLI Giacomo GAVINA Stefano RAVAGLIA Rossana Monica FERRARA 2016Pedosphere2016,26,4:8
4Mechanisms of resistance to anti-epidermal growth factor receptor inhibitors in metastatic colorectal cancer显示文摘The prognosis of patients with metastatic colorectal cancer(m CRC) remain poor despite the impressive improvement of treatments observed over the last 20 years that led to an increase in median overall survival from 6 mo, with the only best supportive care, to approximately 30 mo with the introduction of active chemotherapy drugs and targeted agents. The monoclonal antibodies(mo Abs) cetuximab and panitumumab, directed against the epidermal growth factor receptor(EGFR), undoubtedly represent a major step forward in the treatment of m CRC, given the relevant efficacy in terms of progression-free survival, overall survival, response rate, and quality of life observed in several phase Ⅲ clinical trials among different lines of treatment. However, the anti-EGFR mo Abs were shown only to be effective in a subset of patients. For instance, KRAS and NRAS mutations have been identified as biomarkers of resistance to these drugs, improving the selection of patients who might derive a benefit from these treatments. Nevertheless, several other alterations might affect the response to these drugs, and unfortunately, even the responders eventually become resistant by developing secondary(or acquired) resistance in approximately 13-18 mo. Several studies highlighted that the landscape of responsible alterations of both primary and acquired resistance to anti-EGFR drugs biochemically converge into MEK-ERK and PIK3CA-AKT pathways. In this review, we describe the currently known mechanisms of primary and acquired resistance to anti-EGFR mo Abs together with the various strategies evaluated to prevent, overcame or revert them.Vincenzo Sforza Erika Martinelli Fortunato Ciardiello Valentina Gambardella Stefania Napolitano Giulia Martini Carminia della Corte Claudia Cardone Marianna L Ferrara Alfonso Reginelli Giuseppina Liguori Giulio Belli Teresa Troiani 2016World Journal of Gastroenterology2016,22,28:6

6Prevalence of Helicobacter pylori infection and intestinal metaplasia in subjects who had undergone surgery for gastric adenocarcinoma in Northwest Italy显示文摘AIM: To investigate the seroprevalence of Helicobacter pylori(H pylorri) infection and its more virulent strains as well as the correlation with the histologic features among patients who had undergone surgery for gastric cancer (GC).METHODS: Samples from 317 (184 males, 133females, mean age 69±3.4 years) consecutive patients who had undergone surgery for gastric non-cardia adenocarcinoma were included in the study. Five hundred and fifty-five (294 males, 261 females, mean age 57.3±4.1 years) patients consecutively admitted to the Emergency Care Unit served as control. Histological examination of tumor, lymph nodes and other tissues obtained at the time of surgery represented the diagnostic 'gold standard'. An enzyme immunosorbent assay was used to detect serum anti-H pylori(IgG)antibodies and Western blotting technique was utilized to search for anti-CagA protein (IgG).RESULTS: Two hundred and sixty-one of three hundred and seventeen (82.3%) GC patients and 314/555 (56.5%)controls were seropositive for anti-H pylori (P<0.0001;OR, 3.58; 95%CI, 2.53-5.07). Out of the 317 cases, 267(84.2%) were seropositive for anti-CagA antibody vs 100 out of 555 (18%) controls (P<0.0001; OR, 24.30;95%CI, 16.5-35.9). There was no difference between the frequency of H pyloriin intestinal type carcinoma (76.2%) and diffuse type cancer (78.8%). Intestinal metaplasia (IM) was more frequent but not significant in the intestinal type cancer (83.4% vs 75.2% in diffuse type and 72.5% in mixed type). Among the patients examined for IM, 39.8% had IM type Ⅰ, 8.3% type Ⅱ and 51.9% type Ⅲ (type Ⅲ vs others, P = 0.4).CONCLUSION; This study confirms a high seroprevalence of H pyloriinfection in patients suffering from gastric adenocarcinoma and provides further evidence that searching for CagA status over H pylori infection might confer additional benefit in identifying populations at greater risk for this tumor.Giorgio Palestro Rinaldo Pellicano Gian Ruggero Fronda Guido Valente Marco De Giuli Tito Soldati Agostino Pugliese Stefano Taraglio Mauro Garino Donata Campra Miguel Angel Cutufia Elena Margaria Giancarlo Spinzi Aldo Ferrara Giorgio Marenco Mario Rizzetto Antonio Ponzetto 2005World Journal of Gastroenterology2005,11,45:5

8Helicobacter pylori infection and atopic diseases:Is there a relationship? A systematic review and meta-analysis显示文摘AIM:To review and conduct a meta-analysis of the existing literature on the relationship between Helicobacter pylori(H.pylori),atopy and allergic diseases.METHODS:Studies published in English assessing the prevalence of atopy and/or allergic diseases in patients with H.pylori infection and the prevalence of H.pylori infection in patients with atopy and/or allergic diseases were identified through a MEDLINE search(1950-2014).Random-effect model was used for the meta-analysis.RESULTS:Pooled results of case-control studies showed a significant inverse association of H.pylori infection with atopy/allergic disease or with exclusively atopy,but not with allergic disease,whereas pooled results of cross-sectional studies showed only a significant association between allergic disease and H.pylori infection.CONCLUSION:There is some evidence of an inverse association between atopy/allergic diseases and H.pylori infection,although further studied are needed.Elena Lionetti Salvatore Leonardi Angela Lanzafame Maria Teresa Garozzo Martina Filippelli Stefania Tomarchio Viviana Ferrara Carmelo Salpietro Alfredo Pulvirenti Ruggiero Francavilla Carlo Catassi 2014World Journal of Gastroenterology2014,20,46:3
9Solid lipid nanoparticles delivering anti-inflammatory drugs to treat inflammatory bowel disease: Effects in an in vivo model显示文摘AIM To improve anti-inflammatory activity while reducing drug doses, we developed a nanoformulation carrying dexamethasone and butyrate.METHODS Dexamethasone cholesteryl butyrate-solid lipid nanoparticles(Dx Cb-SLN) were obtained with the warm microemulsion method. The anti-inflammatory activity of this novel nanoformulation has been investigated in vitro(cell adhesion to human vascular endothelial cells and pro-inflammatory cytokine release by lipopolysaccharideinduced polymorphonuclear cells) and in vivo(disease activity index and cytokine plasma concentrations in a dextran sulfate sodium-induced mouse colitis) models. Each drug was also administered separately to compare its effects with those induced by their co-administration in SLN at the same concentrations.RESULTS Dx Cb-SLN at the lowest concentration tested(Dx 2.5 nmol/L and Cb 0.1 μmol/L) were able to exert a more than additive effect compared to the sum of the individual effects of each drug, inducing a significant in vitro inhibition of cell adhesion and a significant decrease of pro-inflammatory cytokine(IL-1β and TNF-α) in both in vitro and in vivo models. Notably, only the Dx Cb nanoformulation administration was able to achieve a significant cytokine decrease compared to the cytokine plasma concentration of the untreated mice with dextran sulfate sodium-induced colitis. Specifically, Dx Cb-SLN induced a IL-1β plasma concentration of 61.77% ± 3.19%, whereas Dx or Cb used separately induced a concentration of 90.0% ± 2.8% and 91.40% ± 7.5%, respectively; Dx Cb-SLN induced a TNF-α plasma concentration of 30.8% ± 8.9%, whereas Dx or Cb used separately induced ones of 99.5% ± 4.9% and 71.1% ± 10.9%, respectively.CONCLUSION Our results indicate that the co-administration of dexamethasone and butyrate by nanoparticles may be beneficial for inflammatory bowel disease treatment.Chiara Dianzani Federica Foglietta Benedetta Ferrara Arianna Carolina Rosa Elisabetta Muntoni Paolo Gasco Carlo Della Pepa Roberto Canaparo Loredana Serpe 2017World Journal of Gastroenterology2017,23,23:3
10Evaluation of anterior and posterior surfaces of the cornea using a dual Scheimpflug analyzer in keratoconus patients implanted with intrastromal corneal ring segments显示文摘AIM:To evaluate corneal parameters measured with a dual Scheimpflug analyzer in keratoconus patients implanted with intrastromal corneal ring segments(ICRS).METHODS:Fifty eyes of 40 keratoconus patients had Ferrara ICRS implantation from November 2010 to April2014.Uncorrected visual acuity(UCVA),best corrected visual acuity(BCVA),refraction,keratometry,asphericity,elevation,pachymetry,root mean square(RMS),spherical aberration and coma were studied.All patients were evaluated using a dual Scheimpflug system.RESULTS:The mean follow-up time after the procedure was 12.7mo.The mean UCVA improved from0.82 to 0.31(P<0.001);the mean BCVA improved from0.42 to 0.05(P<0.0001),the mean spherical refraction changed from-3.06 ±3.80 D to-0.80 ±2.5 D(P<0.0001)and the mean refraction astigmatism reduced from-4.51 ±2.08 D to-2.26±1.18 D(P<0.0001).The changes from preoperative to postoperative,in parameters of the anterior and posterior surface of the cornea,were statistically significant except the elevation posterior at the apex of the cornea and posterior asphericity.CONCLUSION:The implantation of Ferrara ICRS induces changes in both anterior and posterior surfaces of the cornea.Leonardo Torquetti Carlos Arce Jesus Merayo-Lloves Guilherme Ferrara Paulo Ferrara Breenno Signorelli Armando Signorelli 2016International Journal of Ophthalmology(English edition)2016,9,9:3

12Clinical outcomes after implantation of a new intrastromal corneal ring with 140-degree of arc in patients with corneal ectasia显示文摘AIM:To evaluate the clinical and tomographic outcomes after implantation of a new intrastromal corneal ring segment(ICRS) with 140-degrees of arc in eyes with corneal ectasia.METHODS:We evaluated patients with corneal ectasia implanted with Ferrara 140° ICRS from April 2010 to February 2015.Outcome measures included preoperative and postoperative corrected distance visual acuity(CDVA),keratometry simulated(K) reading,tomographic astigmatism and asphericity.All patients were evaluated using the Pentacam Scheimpflug system.RESULTS:The study evaluated 58 eyes.The mean followup was 16.81±10.8 mo.The CDVA(logM AR) improved from 0.5±0.20(20/60) to 0.3±0.21(20/40)(P<0.01).The average K reduced from 49.87±7.01 to 47.34±4.90 D(P<0.01).The asphericity changed from-0.60±0.86 to-0.23±0.67 D(P<0.01).The mean preoperative tomographic astigmatism decreased from-8.0±3.45 to-4.53±2.52 D(P<0.01).CONCLUSION:The new ICRS model with 140-degrees of arc effectively improve the visual acuity and reduce the high astigmatism usually found in patients with corneal ectasia.Jordana Sandes Larissa R.S.Stival Marcos Pereira de Avila Paulo Ferrara Guilherme Ferrara Leopoldo Magacho Luana P.N.Araujo Leonardo Torquetti 2018International Journal of Ophthalmology(English edition)2018,11,5:2
13Balanced propofol sedation administered by nonanesthesiologists:The first Italian experience显示文摘AIM:To assess the efficacy and safety of a balanced approach using midazolam in combination with propofol,administered by nonanesthesiologists,in a large series of diagnostic colonoscopies.METHODS:Consecutive patients undergoing diagnostic colonoscopy were sedated with a single dose of midazolam(0.05 mg/kg)and lowdose propofol(starter bolus of 0.5 mg/kg and repeated boluses of 10 to 20 mg).Induction time and deepest level of sedation,adverse and serious adverse events,as well as recovery times,were prospectively assessed.Cecal intubation and adenoma detection rates were also collected.RESULTS:Overall,1593 eligible patients were included.The median dose of propofol administered was 70 mg(range:40120 mg),and the median dose of midazolam was 2.3 mg(range:24 mg).Median induction time of sedation was 3 min(range:14 min),and median recovery time was 23 min(range:1040 min).A moderate level of sedation was achieved in 1561(98%) patients,whilst a deep sedation occurred in 32(2%) cases.Transient oxygen desaturation requiring further oxygen supplementation occurred in 8(0.46%;95% CI:0.2%0.8%)patients.No serious adverse event was observed.Cecal intubation and adenoma detection rates were 93.5%and 23.4%(27.8%for male and 18.5%for female,subjects),respectively.CONCLUSION:A balanced sedation protocol provided a minimalization of the dose of propofol needed to target a moderate sedation for colonoscopy,resulting in a high safety profile for nonanesthesiologist propofol sedation.Alessandro Repici Nico Pagano Cesare Hassan Alessandra Carlino Giacomo Rando Giuseppe Strangio Fabio Romeo Angelo Zullo Elisa Ferrara Eva Vitetta Daniel de Paula Pessoa Ferreira Silvio Danese Massimo Arosio Alberto Malesci 2011World Journal of Gastroenterology2011,17,33:2
