Abstract
BACKGROUND The frequency and patterns of use of scores for the assessment of endoscopic activity in inflammatory bowel disease patients are not known. AIM To describe the prevalence of adequate use of endoscopic scores in IBD patients who underwent colonoscopy in a real-life setting. MATERIALS AND METHODS A multicenter observational study comprising six community hospitals in Argentina was undertaken. Patients with a diagnosis of Crohn's disease or ulcerative colitis who underwent colonoscopy for endoscopic activity assessment between 2018 and 2022 were included. Colonoscopy reports of included subjects were manually reviewed to determine the proportion of colonoscopies that included an endoscopic score report. We determined the proportion of colonoscopy reports that included all of the IBD colonoscopy report quality elements proposed by BRIDGe group. Endoscopist's specialty, years of experience as well as expertise in IBD were assessed. RESULTS A total of 1556 patients were included for analysis (31.94% patients with Crohn's disease). Mean age was 45.94±15.46. Endoscopic score reporting was found in 58.41% of colonoscopies. Most frequently used scores were Mayo endoscopic score (90.56%) and SES-CD (56.03%) for ulcerative colitis and Crohn's disease, respectively. In addition, 79.11% of endoscopic reports failed to comply with all recommendations on endoscopic reporting for inflammatory bowel disease. CONCLUSIONS A significant proportion of endoscopic reports of inflammatory bowel disease patients do not include the description of an endoscopic score to assess mucosal inflammatory activity in a real-world setting. This is also associated with a lack of compliance in recommended criteria for proper endoscopic reporting.

Abstract
Background Healthy individuals within families with multiple affected members (multiplex families) with Crohn’s disease (CD) have a notably high risk of developing CD. No large prospective pre-disease cohort has assessed differences in preclinical intestinal inflammation, permeability, fecal microbiome, and genetics in healthy at-risk subjects from multiplex families. Purpose We aimed to assess differences in subclinical gut inflammation, genetic risk, gut barrier function, and fecal microbiota composition between first-degree relatives (FDRs) from families with 2 or more affected members (multiplex) and families with only one affected member (simplex). Also, we aimed to assess the risk of future CD onset in subjects from multiplex versus simplex families. Method We utilized the GEM Project cohort of healthy FDRs of CD patients. Subclinical gut inflammation was assessed using fecal calprotectin (FCP) at recruitment. Gut barrier function was assessed using the lactulose-to-mannitol ratio (LMR). For assessment of the CD-related genetic risk, CD-polygenic risk scores (CD-PRS) were calculated. Microbiome composition was assessed by sequencing fecal 16S ribosomal RNA. Generalized estimating equations logistic regression and LEfSe (PMID: 21702898) were used to assess the associations between multiplex status and different outcomes. A Cox proportional hazards model was used to assess time-related risk of future onset of CD. Result(s) 4385 subjects were included. Median age was 17 [IQR 12-24] years, 52.9% were female, 69.4% were siblings and 30.6% were offspring. 4052 (92.4%) and 333 (7.6 %) were simplex and multiplex subjects, respectively. After adjusting for age, sex, family size, and relation to proband, multiplex status was significantly associated with higher baseline FCP (p=0.038), but was not associated with either baseline LMR or CD-PRS (p=0.19 and p=0.33, respectively). We found no significant differences in alpha diversity (Shannon index) (p=0.57) between simplex and multiplex subjects. Beta diversity analysis assessed by the Bray-Curtis dissimilarity index did not reveal significant differences (R2=3e-04, p=0.607). The genera Eisenbergiella, Eggerthellaceae uncultured, and Morganella, were significantly more abundant in multiplex subjects, whereas Lachnospira, Sutterella, Lachnospiraceae_NK4A136_group, and Lachnospiraceae_UCG_004 less abundant. The risk of CD onset was significantly higher in multiplex subjects. In multivariable analysis, multiplex status at recruitment was associated with increased risk of CD onset (adjusted HR 3.41, 95% CI 1.70-6.87, p=0.00055), after adjusting for demographics, FCP, LMR, and CD-PRS. Conclusion(s) Multiplex status compared to simplex is associated with a 3.4-fold increased risk of CD onset, a higher FCP, and fecal bacterial composition. A comprehensive assessment of environmental factors that increase CD risk in multiplex families remains to be elucidated in future studies. Disclosure of Interest None Declared

Abstract
Stem rust, caused by Puccinia graminis, is a destructive group of diseases. The pathogen uses Berberis species as alternate hosts to complete its life cycle. B. vulgaris and the endemic species B. hispanica and B. garciae are present in Spain. The objective of this study was to investigate the functionality of the indigenous barberry as alternate hosts. Field surveys were conducted in 2018 and 2019 in Huesca, Teruel and Albacete provinces of Spain. Aecial samples on barberry were analysed via infection assays and DNA analysis. B. garciae was predominant in Huesca and Teruel provinces, often found in the field margins of cereal crops. Aecial infections on B. garciae were observed in May and uredinial infections on cereal crops in June. Scattered B. hispanica bushes were occasionally found near cereal crops in Albacete, where aecial infections on B. hispanica were observed in June when most cereal crops were mature. Infection assays using aeciospores resulted in stem rust infections on susceptible genotypes of wheat, barley, rye and oat, indicating the presence of the sexual cycle for P. graminis f. sp. tritici, f. sp. secalis and f. sp. avenae. Sequence analyses from aecial samples supported this finding as well as the presence of Puccinia brachypodii. This study provides the first evidence that indigenous Berberis species play an active role in the sexual cycle of P. graminis under natural conditions in Spain.

Abstract
Many of the major stem rust resistance genes deployed in commercial wheat (Triticum spp.) cultivars and breeding lines become ineffective over time because of the continuous emergence of virulent races. A genome-wide association study (GWAS) was conducted using 26,439 single nucleotide polymorphism (SNP) markers and 280 durum wheat [Triticum turgidum L. subsp. Durum (Desf.) Husnot] lines from CIMMYT to identify genomic regions associated with seedling resistance to races TTKSK, TKTTF, JRCQC, and TTRTF and field resistance to TKTTF and JRCQC. The phenotypic data analysis across environments revealed 61-91 and 59-77% of phenotypic variation was explained by the genotypic component for seedling and adult plant response of lines, respectively. For seedling resistance, mixed linear model (MLM) identified eight novel and nine previously reported quantitative trait loci (QTL) while a fixed and random model circulating probability unification (FarmCPU) detected 12 novel and eight previously reported QTL. For field resistance, MLM identified 12 novel and seven previously reported loci while FarmCPU identified seven novel and nine previously reported loci. The regions of Sr7a, Sr8155B1, Sr11, alleles of Sr13, Sr17, Sr22/Sr25, and Sr49 were identified. Novel loci on chromosomes 3B, 4A, 6A, 6B, 7A, and 7B could be used as sources of resistance to the races virulent on durum wheat. Two large-effect markers on chromosome 6A could potentially be used to differentiate resistant haplotypes of Sr13 (R1 and R3). Allelism tests for Sr13, breaking the deleterious effect associated with Sr22/Sr25 and retaining the resistance allele at the Sr49 locus, are needed to protect future varieties from emerging races.

Abstract
UNLABELLED BACKGROUND AND AIMS: There is conflicting evidence regarding the impact of hypothetical cumulative fatigue after performing too many endoscopic procedures on both polyp and adenoma detection rates (PDR, and ADR, respectively). The aim of this study is to evaluate the effect of successive endoscopic procedures on PDR and ADR. METHODS A retrospective cross-sectional study was undertaken among consecutive patients on whom colonoscopy and/or esophagogastroduodenoscopy were performed between January 2012 and August 2014. Data regarding polyp and adenoma detection, cecal intubation, and bowel cleansing quality as well as demographical data of subjects were extracted. Endoscopic procedures were classified according to the time slots of the procedures throughout the endoscopy session in three groups: from the 1st to 4th endoscopy study (round 1), from the 5th to the 8th study (round 2), above the 9th study (round 3). We compared PDR and ADR among rounds. RESULTS Overall, 3388 patients were enrolled. Median age was 50 years (range 18-95) and 52.39% were female. There was a significant difference in terms of PDR among rounds (36.83%, 41.24%, and 43.38%, respectively, p = 0.007) and a non-significant numerical difference when ADR was compared (23.2%, 25.71%, and 26.78%, p = 0.07). On multivariate analysis, ADR was significantly associated with age (odds ratio [OR] 1.02 [1.01-1.03]), and male sex (OR 1.64 [1.38-1.94]). CONCLUSION Theoretical endoscopist's fatigue due to cumulative performance of endoscopies does not diminish colonoscopy quality. Both PDR and ADR seem to improve after endoscopist's cumulative rounds of performed endoscopies. This could be due to a "warm-up" effect.

Abstract
Inflammatory bowel disease comprises two distinct conditions - Crohn's disease and ulcerative colitis - which can be treated with immunomodulators. A non-neglectable proportion of these patients will need biologic therapy, and many patients under biologic treatment will experience either primary or secondary failure. As a consequence, clinical trials evaluating new therapeutic alternatives are being developed. These trials share common features, such as being controlled with placebo. Placebo use in clinical trials is a matter of intense debate. Those who support placebo use highlight the methodologic advantages placebo-controlled trials have. Those against placebo use argue that it would be against ethical principles in clinical research to expose a patient to placebo when a valid therapeutic alternative exists. In this review, we summarize the existing arguments for and against the use of placebo in the context of inflammatory bowel disease research. We finally suggest that it is very likely that in the near future inflammatory bowel disease trials will no longer be controlled with a placebo arm, but instead they will be non-inferiority trials with an active comparator.

Abstract
METHODS A multicenter cross-sectional study involving seven referral centers from three cities of Argentina was undertaken. Patients with a diagnosis of ulcerative colitis (UC), Crohn's disease (CD), or indeterminate colitis (IBDU/IC) were invited to answer an anonymous survey, which included a 5-point Likert scale to evaluate adherence to therapies. Independent variables associated with inadequate adherence were evaluated. RESULTS Overall, 447 UC/IBDU and 135 CD patients were enrolled. Median age was 37 years (range 21-72); 39.8% were male; median time from diagnosis was 6 years (0.5-35). 91.4% were under treatment with at least one oral medication; 50.3% of patients reported inadequate adherence to oral medications. Patients with UC/IBDU had a lower risk of inadequate adherence when compared to patients with CD (OR 0.57 (0.37-0.87)). 21.8% reported inadequate adherence to biologics; subcutaneous administration was significantly associated with inadequate adherence to biologics (OR 4.8 (1.57-14.66)). CONCLUSION Inadequate treatment adherence is common among patients with IBD, and potentially modifiable factors were identified.

Abstract
In Ethiopia, breeding rust resistant wheat cultivars is a priority for wheat production. A stem rust epidemic during 2013 to 2014 on previously resistant cultivar Digalu highlighted the need to determine the effectiveness of wheat lines to multiple races of Puccinia graminis f. sp. tritici in Ethiopia. During 2014 and 2015, we evaluated a total of 97 bread wheat and 14 durum wheat genotypes against four P. graminis f. sp. tritici races at the seedling stage and in single-race field nurseries. Resistance genes were postulated using molecular marker assays. Bread wheat lines were resistant to race JRCQC, the race most virulent to durum wheat. Lines with stem rust resistance gene Sr24 possessed the most effective resistance to the four races. Only three lines with adult plant resistance possessed resistance effective to the four races comparable with cultivars with Sr24. Although responses of the wheat lines across races were positively correlated, wheat lines were identified that possessed adult plant resistance to race TTKSK but were relatively susceptible to race TKTTF. This study demonstrated the importance of testing wheat lines for response to multiple races of the stem rust pathogen to determine if lines possessed non-race-specific resistance.

Abstract
Big data methodologies, made possible with the increasing generation and availability of digital data and enhanced analytical capabilities, have produced new insights to improve outcomes in many disciplines. Application of big data in the health-care sector is in its early stages, although the potential for leveraging underutilized data to gain a better understanding of disease and improve quality of care is enormous. Owing to the intrinsic characteristics of inflammatory bowel disease (IBD) and the management dilemmas that it imposes, the implementation of big data research strategies not only can complement current research efforts but also could represent the only way to disentangle the complexity of the disease. In this Review, we explore important potential applications of big data in IBD research, including predictive models of disease course and response to therapy, characterization of disease heterogeneity, drug safety and development, precision medicine and cost-effectiveness of care. We also discuss the strengths and limitations of potential data sources that big data analytics could draw from in the field of IBD, including electronic health records, clinical trial data, e-health applications and genomic, transcriptomic, proteomic, metabolomic and microbiomic data.

Abstract
BACKGROUND Biologics against tumor necrosis factor (anti-TNF) have dramatically changed the management of moderate-to-severe ulcerative colitis (UC). In pivotal clinical trials, golimumab showed efficacy as induction and maintenance therapy in anti-TNF naïve UC patients. However, confirmatory data on effectiveness in the real world setting are needed. AIM to summarize recent evidence on the effectiveness of golimumab in observational real-world studies. METHODS A literature search was conducted using Medline, Embase, and congresses databases for English language articles or abstracts on the effectiveness of golimumab published between January 1, 2014 and May 15, 2018. Pooled short-term (6-14 weeks) and mid- and long-term (24-54 weeks) clinical response and remission rates were calculated. RESULTS 24 abstracts were included; of those 8 were published full-text articles and 16 were abstracts from medical conferences. Overall, pooled short-term clinical response and remission rates were 59.3% (range 35-85.5%; 13 studies; 1429 patients) and 35.9% (range 14-51.7%; 9 studies; 666 patients), respectively. Pooled mid- and long-term clinical response and remission rates were 60.3% (range 37.1-89.5%; 4 studies; 356 patients) and 39.2% (range 12-84%; 8 studies; 822 patients), respectively. CONCLUSIONS Results: of observational studies confirm that golimumab is an effective therapy for UC in clinical practice.

Abstract
BACKGROUND Several novel compounds are being developed for inflammatory bowel diseases (IBD). In addition, biosimilar drugs are being approved. An increasing number of head-to-head, superiority and non-inferiority trials in patients with IBD are expected in the future. The clinical relevance of the magnitude of the effect size is often debated. AIM To better understand physicians' perspectives on the clinical meaningfulness of IBD trial results. METHODS We conducted an online survey among all IOIBD (International Organization for the Study of Inflammatory Bowel Diseases) members, asking their opinion on the clinical relevance of the results of IBD trials. RESULTS Forty-six IOIBD members responded to the survey (52.3%). In biologic-naïve ulcerative colitis (UC) and Crohn's disease (CD) patients, most of the participants considered a 15% difference with placebo for clinical remission and endoscopic remission to be clinically relevant. In head-to-head trials, most of participants considerer a 10% difference between groups for clinical remission and endoscopic remission to be clinically relevant. Half of respondents considered 10% to be an adequate margin in non-inferiority trials. In bioequivalence studies, most of the participants considered adequate a ± 5% difference between a biosimilar and the originator for pharmacokinetic parameters, efficacy, safety and immunogenicity. Regarding safety, the difference between two drugs considered clinically relevant varied from 1% to 5%, depending on the type of adverse event. CONCLUSIONS This is the first survey exploring how physicians perceive IBD trial results, providing an estimation of the magnitude of the difference between treatment arms that may directly influence clinical practice.

Abstract
Wheat stem rust, caused by Puccinia graminis f. sp. tritici Eriks. & E. Henn, can incur yield losses in susceptible cultivars of durum wheat, Triticum turgidum ssp. durum (Desf.) Husnot. Although several durum cultivars possess the stem rust resistance gene Sr13, additional genes in durum wheat effective against emerging virulent races have not been described. Durum line 8155-B1 confers resistance against the P. graminis f. sp. tritici race TTKST, the variant race of the Ug99 race group with additional virulence to wheat stem rust resistance gene Sr24 However, 8155-B1 does not confer resistance to the first-described race in the Ug99 race group: TTKSK. We mapped a single gene conferring resistance in 8155-B1 against race TTKST, Sr8155B1, to chromosome arm 6AS by utilizing Rusty/8155-B1 and Rusty*2/8155-B1 populations and the 90K Infinium iSelect Custom bead chip supplemented by KASP assays. One marker, KASP_6AS_IWB10558, cosegregated with Sr8155B1 in both populations and correctly predicted Sr8155B1 presence or absence in 11 durum cultivars tested. We confirmed the presence of Sr8155B1 in cultivar Mountrail by mapping in the population Choteau/Mountrail. The marker developed in this study could be used to predict the presence of resistance to race TTKST in uncharacterized durum breeding lines, and also to combine Sr8155B1 with resistance genes effective to Ug99 such as Sr13 The map location of Sr8155B1 cannot rule out the possibility that this gene is an allele at the Sr8 locus. However, race specificity indicates that Sr8155B1 is different from the known alleles Sr8a and Sr8b.

Abstract
BACKGROUND There are currently no guidelines on the need to assess disease activity before stoma reversal in Crohn's disease (CD). We sought to determine the value of cross-sectional imaging for detecting active CD before stoma reversal. METHODS 38 CD patients underwent cross-sectional imaging before stoma reversal. CD activity was blindly evaluated by an independent radiologist. Postoperative outcomes were recorded. RESULTS Before stoma reversal, cross-sectional imaging identified active CD in 20 of the 38 study participants (52.6%). In 9 out of 10 tested patients, radiologic and endoscopic assessments gave concordant findings with regard to CD recurrence before stoma reversal. Stoma reversal was delayed in half of the patients with active CD and in none of the patients without active CD. Before stoma reversal, tumor necrosis factor alpha antagonists or immunosuppressants were initiated in 45% of the patients with active CD and 5.6% of the patients without active CD. In the year following stoma reversal, the recurrence rate (in a radiologic assessment) was higher in patients with active CD than in patients without active CD (75.0% vs. 30.8%, respectively; p=0.04). CONCLUSION Cross-sectional imaging revealed postoperative recurrence in about a quarter of patients before stoma reversal; this finding may influence the postoperative treatment strategy and outcomes.

Abstract
PURPOSE OF REVIEW The aim of this review is to summarize data regarding surgical trends in inflammatory bowel disease in the prebiologic and biologic era, with a focus on population-based studies and randomized controlled trials (RCTs). RECENT FINDINGS There is paucity of data in RCTs regarding surgical rates, with only a few clinical trials reporting them. From the available data, meta-analyses of RCTs have concluded that antitumor necrosis α agents (anti-TNF) reduce surgical rates in ulcerative colitis and Crohn's disease. A large body of evidence from population-based studies from different regions of the world is available to evaluate surgical trends before and after the introduction of anti-TNF agents. The risk of surgery decreased significantly over the past six decades; these decreasing trends continued in the biologic era, which might indicate a potential beneficial disease-modifying effect of biologics. There is lack of data with nonanti-TNF biologics (i.e. anti-integrins and ustekinumab) regarding the risk of surgery. SUMMARY Although data from population-based studies and available RCTs suggest a protective effect from surgery of anti-TNF agents, definitive conclusions should be drawn only when more disease-modifying trials with different biologics and treatment strategies become available.

Abstract
BACKGROUND There is a wide heterogeneity in the reports of celiac disease prevalence in iron-deficiency anemia patients. AIM To determine the prevalence of celiac disease in patients with iron-deficiency anemia. MATERIALS AND METHODS Adult patients with a diagnosis of iron-deficiency anemia were enrolled for upper endoscopy with duodenal biopsies. Healthy volunteers that underwent upper endoscopy were enrolled as controls. RESULTS A total of 135 patients with iron-deficiency anemia and 133 controls were enrolled. Celiac disease prevalence was higher in the iron-deficiency anemia group [11.11 vs. 1.51%, OR: 8.18 (1.83-36.55), P=.001). Of the celiac disease patients in the iron-deficiency anemia group, 73.3% had at least one endoscopic sign suggesting villous atrophy, whereas 100% of the celiac disease patients in the control group presented with at least one endoscopic sign. CONCLUSIONS Patients with iron-deficiency anemia have an increased risk for celiac disease. Up to 25% of these patients may not present any endoscopic sign suggesting villous atrophy.

Abstract
BACKGROUND Crohn's disease (CD) and rheumatoid arthritis are chronic, progressive and disabling conditions that frequently lead to structural tissue damage. Based on strategies originally developed for rheumatoid arthritis, the treatment goal for CD has recently moved from exclusively controlling symptoms to both clinical remission and complete mucosal healing (deep remission), with the final aim of preventing bowel damage and disability. AIM To review the similarities and differences in treatment goals between CD and rheumatoid arthritis. METHODS This review examined manuscripts from 1982 to 2016 that discussed and/or proposed therapeutic goals with their supportive evidence in CD and rheumatoid arthritis. RESULTS Proposed therapeutic strategies to improve outcomes in both rheumatoid arthritis and CD include: (i) evaluation of musculoskeletal or organ damage and disability, (ii) tight control, (iii) treat-to-target, (iv) early intervention and (v) disease modification. In contrast to rheumatoid arthritis, there is a paucity of disease-modification trials in CD. CONCLUSIONS Novel therapeutic strategies in CD based on tight control of objective signs of inflammation are expected to change disease course and patients' lives by halting progression or, ideally, preventing the occurrence of bowel damage. Most of these strategies require validation in prospective studies, whereas several disease-modification trials have addressed these issues in rheumatoid arthritis over the last decade. The recent approval of new drugs in CD such as vedolizumab and ustekinumab should facilitate initiation of disease-modification trials in CD in the near future.

Abstract
BACKGROUND There is evidence that shows that calcineurin inhibitors may be useful for the treatment of severe ulcerative colitis. However, evidence regarding the efficacy of tacrolimus for remission induction in this setting is scarce. OBJECTIVE To develop a systematic review on the existing evidence regarding the clinical efficacy of tacrolimus for the induction of remission in patients with moderate-to-severe ulcerative colitis. METHODS A literature search was undertaken from 1966 to August 2016 using MEDLINE, Embase, LILACS and the Cochrane Library. The following MeSH terms were used: "Inflammatory Bowel Diseases" or "Ulcerative Colitis" and "Calcineurin Inhibitors" or "Tacrolimus" or "FK506". Studies performed in adult ulcerative colitis patients that evaluated the clinical efficacy of tacrolimus for the induction of remission were considered for revision. A meta-analysis was performed with those included studies that were also placebo-controlled and randomized. Clinical response as well as clinical remission and mucosal healing were evaluated. RESULTS Overall, 755 references were identified, from which 22 studies were finally included. Only two of them were randomized, placebo-controlled trials. A total of 172 patients were evaluated. A significantly lower risk of failure in clinical response was found for tacrolimus versus placebo [RR 0.58 (0.45-0.73)]; moreover, a lower risk of failure in the induction of remission was also found versus placebo [RR 0.91 (0.82-1)]. CONCLUSION Tacrolimus seems to be a valid therapeutic alternative for the induction of remission in patients with moderate-to-severe ulcerative colitis.

Abstract
Wheat stem rust, caused by Puccinia graminis f. sp. tritici, can cause severe yield losses on susceptible wheat varieties and cultivars. Although stem rust can be controlled by the use of genetic resistance, population dynamics of P. graminis f. sp. tritici can frequently lead to defeat of wheat stem rust resistance genes. P. graminis f. sp. tritici race TKTTF caused a severe epidemic in Ethiopia on Ug99-resistant 'Digalu' in 2013 and 2014. The gene Sr11 confers resistance to race TKTTF and is present in 'Gabo 56'. We identified seven single-nucleotide polymorphism (SNP) markers linked to Sr11 from a cross between Gabo 56 and 'Chinese Spring' exploiting a 90K Infinium iSelect Custom beadchip. Five SNP markers were validated on a 'Berkut'/'Scalavatis' population that segregated for Sr11, using KBioscience competitive allele-specific polymerase chain reaction (KASP) assays. Two of the SNP markers, KASP_6BL_IWB10724 and KASP_6BL_IWB72471, were predictive of Sr11 among wheat genetic stocks, cultivars, and breeding lines from North America, Ethiopia, and Pakistan. These markers can be utilized to select for Sr11 in wheat breeding and to detect the presence of Sr11 in uncharacterized germplasm.

Abstract
A severe stem rust epidemic occurred in southern Ethiopia during November 2013 to January 2014, with yield losses close to 100% on the most widely grown wheat cultivar, 'Digalu'. Sixty-four stem rust samples collected from the regions were analyzed. A meteorological model for airborne spore dispersal was used to identify which regions were most likely to have been infected from postulated sites of initial infection. Based on the analyses of 106 single-pustule isolates derived from these samples, four races of Puccinia graminis f. sp. tritici were identified: TKTTF, TTKSK, RRTTF, and JRCQC. Race TKTTF was found to be the primary cause of the epidemic in the southeastern zones of Bale and Arsi. Isolates of race TKTTF were first identified in samples collected in early October 2013 from West Arsi. It was the sole or predominant race in 31 samples collected from Bale and Arsi zones after the stem rust epidemic was established. Race TTKSK was recovered from 15 samples from Bale and Arsi zones at low frequencies. Genotyping indicated that isolates of race TKTTF belongs to a genetic lineage that is different from the Ug99 race group and is composed of two distinct genetic types. Results from evaluation of selected germplasm indicated that some cultivars and breeding lines resistant to the Ug99 race group are susceptible to race TKTTF. Appearance of race TKTTF and the ensuing epidemic underlines the continuing threats and challenges posed by stem rust not only in East Africa but also to wider-scale wheat production.

Abstract
BACKGROUND Untreated celiac disease has traditionally been linked to a greater risk for small intestinal bacterial overgrowth, but the existing evidence is inconclusive. AIMS To compare the prevalence of small intestinal bacterial overgrowth in subjects with celiac disease compared with control subjects and patients with irritable bowel syndrome. MATERIAL AND METHODS The study included 15 untreated celiac disease patients, 15 subjects with irritable bowel syndrome, and 15 healthy controls. All enrolled patients underwent a lactulose breath test measuring hydrogen and methane. Small intestinal bacterial overgrowth was defined according to previously published criteria. RESULTS No differences were found in relation to age or sex. The prevalence of small intestinal bacterial overgrowth was similar between the celiac disease patients and the controls (20 vs. 13.33%, P=NS), whereas it was higher in patients with irritable bowel syndrome (66.66%, P<05). CONCLUSION There was no difference in the prevalence of small intestinal bacterial overgrowth between the untreated celiac disease patients and healthy controls.

Abstract
Leaf rust, stem rust, and stripe rust are among the most important diseases of wheat and barley worldwide and are best controlled using genetic resistance. To increase the diversity of rust resistance in wheat and barley, a project was initiated to identify and characterise rust resistance genes from the wild species of Aegilops sharonensis (Sharon goatgrass) and Hordeum vulgare ssp. spontaneum (wild barley), respectively. One hundred and two accessions of Sharon goatgrass from Israel and 318 Wild Barley Diversity Collection (WBDC) accessions from the Fertile Crescent, Central Asia, North Africa, and the Caucasus region were evaluated for resistance to leaf rust, stem rust, and/or stripe rust. Sharon goatgrass exhibited a wide range of infection types (ITs) in response to leaf rust, stem rust, and stripe rust. The percentage of resistant accessions in Sharon goatgrass was 58.8–78.4% for leaf rust, 11.8–69.6% for stem rust, and 46.1% for stripe rust, depending on the race used and the plant growth stage. Genetic studies with Sharon goatgrass revealed oligogenic resistance to leaf rust and stem rust. Wild barley also exhibited a wide range of ITs to leaf rust and stem rust; however, the overall frequency of resistance was lower than for Sharon goatgrass. The percentage of resistant accessions in wild barley was 25.8% for leaf rust and 5.7–20.1% for stem rust, depending on the race used. Resistance to the new virulent stem rust race TTKS (i.e. Ug99), present in eastern Africa, was found in both Sharon goatgrass (70% of accessions) and wild barley (25% of 20 accessions tested). Association mapping for stem rust resistance was applied in the WBDC using Diversity Arrays Technology (DArT) markers. Using the highly conservative P value threshold of 0.001, 14 and 15 significant marker associations were detected when the number of subpopulations (K value) was set for 10 and 8, respectively. These significant associations were in 9 and 8 unique chromosome bins, respectively. Two significant marker associations were detected for resistance to the wheat stem rust race MCCF in the same bin as the rpg4/Rpg5 complex on chromosome 7(5H). The presence of a major stem rust resistance gene in this bin on chromosome 7(5H) was validated in a bi-parental mapping population (WBDC accession Damon × cv. Harrington) constructed with DArT markers. The results from this study indicate that Sharon goatgrass and wild barley are rich sources of rust resistance genes for cultivated wheat and barley improvement, respectively, and that association mapping may be useful for positioning disease resistance genes in wild barley.

Abstract
PURPOSE Gemcitabine (2',2'-difluorodeoxycytidine) is an antineoplastic agent with activity against a variety of solid tumors. To investigate its in vitro activity toward cervical cancer, we exposed six cervical cancer cell lines to gemcitabine. METHODS Combinational cytotoxic studies using viability tests and clonogenicity assays. RESULTS Gemcitabine was cytostatic and cytotoxic in some of the lines at peak plasma concentrations similar to those achieved in clinical trials. Gemcitabine was also found to effectively synergize with cisplatin and showed a radiosensitizing effect in these cells. The cytotoxicity observed in sensitive cell lines was due to apoptosis, as demonstrated by DNA fragmentation assays. CONCLUSIONS We recommend performing additional in vitro experimentation so that these results can be confirmed to support clinical trials of gemcitabine in cervical cancer patients both as first-line therapy and with concomitant radiation.

Abstract
Plasma lipids of male golden Syrian hamsters fed diets supplemented with 15% (w/w) rose hip, sunflower, olive, or coconut oils during four weeks were assessed. The results confirm the saturated fat hyperlipidemic effect on golden Syrian hamsters fed with the olive oil and coconut oil, reaching the highest triglyceride levels. The monounsaturated (olive oil) or polyunsaturated (rose hip and sunflower oils) fatty acid-rich-vegetable oils have a similar action on the HDL-cholesterol. No statistically significant difference was observed for total cholesterol, HDL-cholesterol and triglyceride plasma levels in the rose hip and sunflower groups, showing that the polyunsaturation degree of both oils does not affect those results. Compared with the plasma levels obtained in the olive and coconut oil groups, rose hip and sunflower oils present a marked hypolipidemic effect, which could be due to specific action of the series n-6 linoleic acid.

Abstract
Forty-four consecutive cases of "early gastric cancer" were studied according to the macroscopic classification proposed by the Japanese Gastroenterological and Endoscopy Society and further analyzed in terms of growth patterns. The tumours were then classified into the small mucosal type, the superficially spreading (Super) type and the penetrating growth (Pen) type. The Lauren type (intestinal vs. diffuse), presence of lymphatic and venous invasion, and lymph node metastasis were also assessed. Most elevated tumours showed a superficial growth pattern and were classified as Lauren's intestinal type, whereas depressed lesions were associated with submucosal invasion and were classified as diffuse. Microscopic patterns did not show any correlation with Lauren's classification. Mean duration of follow-up was 67.8 months and the overall actuarial survival was 93%, 80%, and 72%, at 2, 5, and 10 years, respectively. Aside from venous invasion no correlation was found between survival and any of the morphological parameters analysed.
