Abstract
BACKGROUND The Inflammatory Bowel Disease-Disk (IBD-Disk) is a physician-administered tool that evaluates the functional status of patients with Inflammatory Bowel Disease (IBD). The aim of our study was to validate the content of the IBD-Disk in a Greek cohort of IBD patients. METHODS Two questionnaires [the IBD Disk and the IBD-Disability Index (IBD-DI)] were translated into Greek and administered to IBD patients at baseline visit, after 4 weeks and 6 months. Validation of the IBD Disk included measuring of concurrent validity, reproducibility, and internal consistency. RESULTS A total of 300 patients were included at baseline and 269 at follow-up. There was a good correlation between the total scores of the IBD-Disk and IBD-DI at baseline (Pearson correlation 0.87, p < 0.001). Reproducibility of the total IBD-Disk score was very good [intra-class correlation coefficient (ICC), 95% confidence interval (CI) 0.89 (0.86-0.91)]. Cronbach's coefficient alpha for all items achieved 0.90 (95%CI 0.88-0.92), demonstrating a very good homogeneity of the IBD-Disk items. Female gender and extraintestinal manifestations were significantly associated with a higher IBD-Disk total score. CONCLUSIONS The Greek version of the IBD-Disk proved to be a reliable and valid tool in detecting and assessing IBD-related disability in a Greek cohort of IBD patients.

Abstract
Engineered nanomaterials (ENMs) enable new and enhanced products and devices in which matter can be controlled at a near-atomic scale (in the range of 1 to 100 nm). However, the unique nanoscale properties that make ENMs attractive may result in as yet poorly known risks to human health and the environment. Thus, new ENMs should be designed in line with the idea of safe-and-sustainable-by-design (SSbD). The biological activity of ENMs is closely related to their physicochemical characteristics, changes in these characteristics may therefore cause changes in the ENMs activity. In this sense, a set of physicochemical characteristics (for example, chemical composition, crystal structure, size, shape, surface structure) creates a unique 'representation' of a given ENM. The usability of these characteristics or nanomaterial descriptors (nanodescriptors) in nanoinformatics methods such as quantitative structure-activity/property relationship (QSAR/QSPR) models, provides exciting opportunities to optimize ENMs at the design stage by improving their functionality and minimizing unforeseen health/environmental hazards. A computational screening of possible versions of novel ENMs would return optimal nanostructures and manage ('design out') hazardous features at the earliest possible manufacturing step. Safe adoption of ENMs on a vast scale will depend on the successful integration of the entire bulk of nanodescriptors extracted experimentally with data from theoretical and computational models. This Review discusses directions for developing appropriate nanomaterial representations and related nanodescriptors to enhance the reliability of computational modelling utilized in designing safer and more sustainable ENMs.

Abstract
BACKGROUND Four EMA-approved vaccines against SARS-CoV-2 are currently available. Data regarding antibody responses to initial vaccination regimens in patients with inflammatory bowel diseases (IBD) are limited. METHODS We conducted a prospective, controlled, multicenter study in tertiary Greek IBD centers. Participating patients had completed the initial vaccination regimens (1 or 2 doses, depending on the type of COVID-19 vaccine) at least 2 weeks before study enrolment. Anti-S1 IgG antibody levels were measured. Demographic and adverse events data were collected. RESULTS We tested 403 patients (Crohn's disease, 58.9%; male, 53.4%; median age, 45 years) and 124 healthy controls (HCs). Following full vaccination, 98% of patients seroconverted, with mRNA vaccines inducing higher seroconversion rates than viral vector vaccines (P = .021). In total, IBD patients had lower anti-S1 levels than HCs (P < .001). In the multivariate analysis, viral vector vaccines (P < .001), longer time to antibody testing (P < .001), anti-TNFα treatment (P = .013), and age (P = .016) were independently associated with lower anti-S1 titers. Vedolizumab monotherapy was associated with higher antibody levels than anti-TNFα or anti-interleukin-12/IL-23 monotherapy (P = .023 and P = .032). All anti- SARS-CoV-2 vaccines were safe. CONCLUSIONS Patients with IBD have impaired antibody responses to anti-SARS-CoV-2 vaccination, particularly those receiving viral vector vaccines and those on anti-TNFα treatment. Older age also hampers antibody production after vaccination. For those low-response groups, administration of accelerated or prioritized booster vaccination may be considered.

Abstract
BACKGROUND The prevalence and incidence of inflammatory bowel diseases (IBDs) vary among countries. Data regarding prevalence of IBD in Greece are limited or outdated. METHODS We reviewed the medical records of IBD patients from a population of 551,808 Greek Army recruits in a 13-year period (2006-2018). Study population consisted of males 18-37 of age from Northwest, Central Greece (including Attica), Peloponnese, and Aegean Sea Islands. Age, disease distribution, pharmaceutical treatment and IBD-related surgery at the time of patients' admission were recorded. RESULTS The prevalence of IBD among male recruits during the studied period was 0.15% (839/551 808, 95% confidence interval 0.14-0.16%). Of these, 448 (53.4%) had Crohn's disease (CD) and 391 (46.6%) ulcerative colitis (UC). Although 32.1% of CD patients had been treated with biologics, most often infliximab (60% of them), azathioprine was the most common as monotherapy (27% of patients). Among UC patients, mesalamine was the most often prescribed treatment (64.2%), whereas treatment with biologics as monotherapy or in combination with azathioprine was used in a ratio 1:2 compared to CD patients. A gradual reduction in steroid use was noted from 2006 to 2018, coinciding with the advent and increasing use of biologics. IBD-related surgery had been performed in 8% and 2.8% of CD and UC patients, respectively. CONCLUSION The prevalence of IBD in Greek male recruits was 0.15% with a slight CD predominance. Remarkable changes in therapeutic trends were noted with an increasing use of biologics and reduced prescription of steroids, especially for CD.

Abstract
Since inflammatory bowel disease (IBD) patients were excluded from vaccine authorization studies, limited knowledge exists regarding perceptions and unfavorable effects of COVID-19 vaccination in this group. We aimed to investigate the real-world use and adverse events (AEs) of COVID-19 vaccines in Greek IBD patients. Fully vaccinated IBD patients followed in Greek centers were invited to participate. All patients filled out an anonymous online survey concerning the vaccination program, which included information regarding demographics, clinical characteristics, treatment, vaccination perceptions and potential AEs. Overall, 1007 IBD patients were included. Vaccine hesitancy was reported by 49%. Total AEs to vaccination were reported by 81% after dose 1 (D1) and 76% after dose 2 (D2), including isolated injection site reactions (36% and 24% respectively). Systemic AEs were more common after D2 (51%, D2 vs. 44%, D1, p < 0.0001). Very few patients reported new onset abdominal symptoms (abdominal pain 4% (D1), 6% (D2) and diarrhea 5% (D1), 7% (D2)). There were no serious AEs leading to emergency room visit or hospitalization. In multivariate analysis, AEs occurrence was positively associated with young age and female gender (p < 0.0005 for both doses), whereas inactive disease was negatively associated with AE in D1 (p = 0.044). SARS-CoV-2 vaccination in Greek IBD patients demonstrated a favorable and reassuring safety profile.

Abstract
BACKGROUND AND AIMS This study aimed to compare real-world clinical effectiveness and safety of vedolizumab, an α4β7-integrin inhibitor, and anti-tumour necrosis factor-α [anti-TNFα] agents in biologic-naïve ulcerative colitis [UC] and Crohn's disease [CD] patients. METHODS This was a 24-month retrospective medical chart study in adult UC and CD patients treated with vedolizumab or anti-TNFα in Canada, Greece and the USA. Inverse probability weighting was used to account for differences between groups. Primary outcomes were cumulative rates of clinical effectiveness [clinical response, clinical remission, mucosal healing] and incidence rates of serious adverse events [SAEs] and serious infections [SIs]. Secondary outcomes included cumulative rates of treatment persistence [patients who did not discontinue index treatment during follow-up] and dose escalation and incidence rates of disease exacerbations and disease-related surgeries. Adjusted analyses were performed using inverse probability weighting. RESULTS A total of 1095 patients [604 UC, 491 CD] were included. By 24 months, rates of clinical effectiveness were similar between groups, but incidence rates of SAEs (hazard ratio [HR] = 0.42 [0.28-0.62]) and SIs (HR = 0.40 [0.19-0.85]) were significantly lower in vedolizumab vs anti-TNFα patients. Rates of treatment persistence [p < 0.01] by 24 months were higher in vedolizumab patients with UC. Incidence rates of disease exacerbations were lower in vedolizumab patients with UC (HR = 0.58 [0.45-0.76]). Other outcomes did not significantly differ between groups. CONCLUSION In this real-world setting, first-line biologic therapy in biologic-naïve patients with UC and CD demonstrated that vedolizumab and anti-TNFα treatments were equally effective at controlling disease symptoms, but vedolizumab has a more favourable safety profile.

Abstract
This study presents the results of applying deep learning methodologies within the ecotoxicology field, with the objective of training predictive models that can support hazard assessment and eventually the design of safer engineered nanomaterials (ENMs). A workflow applying two different deep learning architectures on microscopic images of Daphnia magna is proposed that can automatically detect possible malformations, such as effects on the length of the tail, and the overall size, and uncommon lipid concentrations and lipid deposit shapes, which are due to direct or parental exposure to ENMs. Next, classification models assign specific objects (heart, abdomen/claw) to classes that depend on lipid densities and compare the results with controls. The models are statistically validated in terms of their prediction accuracy on external D. magna images and illustrate that deep learning technologies can be useful in the nanoinformatics field, because they can automate time-consuming manual procedures, accelerate the investigation of adverse effects of ENMs, and facilitate the process of designing safer nanostructures. It may even be possible in the future to predict impacts on subsequent generations from images of parental exposure, reducing the time and cost involved in long-term reproductive toxicity assays over multiple generations.

Abstract
Nanotechnology has enabled the discovery of a multitude of novel materials exhibiting unique physicochemical (PChem) properties compared to their bulk analogues. These properties have led to a rapidly increasing range of commercial applications; this, however, may come at a cost, if an association to long-term health and environmental risks is discovered or even just perceived. Many nanomaterials (NMs) have not yet had their potential adverse biological effects fully assessed, due to costs and time constraints associated with the experimental assessment, frequently involving animals. Here, the available NM libraries are analyzed for their suitability for integration with novel nanoinformatics approaches and for the development of NM specific Integrated Approaches to Testing and Assessment (IATA) for human and environmental risk assessment, all within the NanoSolveIT cloud-platform. These established and well-characterized NM libraries (e.g. NanoMILE, NanoSolutions, NANoREG, NanoFASE, caLIBRAte, NanoTEST and the Nanomaterial Registry (>2000 NMs)) contain physicochemical characterization data as well as data for several relevant biological endpoints, assessed in part using harmonized Organisation for Economic Co-operation and Development (OECD) methods and test guidelines. Integration of such extensive NM information sources with the latest nanoinformatics methods will allow NanoSolveIT to model the relationships between NM structure (morphology), properties and their adverse effects and to predict the effects of other NMs for which less data is available. The project specifically addresses the needs of regulatory agencies and industry to effectively and rapidly evaluate the exposure, NM hazard and risk from nanomaterials and nano-enabled products, enabling implementation of computational 'safe-by-design' approaches to facilitate NM commercialization.

Abstract
AIM To identify factors predicting mucosal healing in ulcerative colitis patients treated with anti-TNFα agents with or without azathioprine. METHODS In a prospective, multicenter, one-year study biologic naïve patients aged 25-65 years, with corticosteroid-dependent or refractory colitis received combination treatment with anti-TNFα and azathioprine for 6 months followed by anti-TNFα monotherapy. Patients who denied combination therapy or were outside this age range received anti-TNFα monotherapy (controls). Before and at weeks 12 and 54 of treatment the total Mayo score was calculated. Mucosal healing was defined as endoscopic subscore of 0. Mucosal expression of T helper (Th) cell-lineage specific transcription factors (Tbet, Gata3, Rorc, FoxP3) before treatment was also associated with mucosal healing. RESULTS Of 67 patients, 58 (86.6%) received combination and 9 (13.4%) anti-TNFα monotherapy. Overall 29 (43.3%) patients achieved mucosal healing; rates were higher in patients receiving combination therapy vs. monotherapy (p=0.03) and in azathioprine naïve vs. exposed patients in the combination group (p=0.01). Mucosal healing was associated with lower pre-treatment mucosal expression of transcription factor Th1-Tbet (p<0.05) and higher expression of Th17-Rorc (p<0.05). CONCLUSIONS Mucosal healing was associated with combination therapy, especially in biologic and azathioprine-naïve patients and pre-treatment mucosal expression of specific Th specific transcripting factors (Tbet and Rorc).

Abstract
BACKGROUND & AIMS Infliximab is a safe and effective therapy for ulcerative colitis (UC). We conducted a multicenter retrospective cohort study that included 7 European countries and Israel to examine whether infliximab discontinuation can be considered for patients who achieve sustained remission. METHODS We performed a retrospective cohort study, collecting medical records from 13 tertiary care referral inflammatory bowel disease centers of all patients with UC treated with infliximab (n = 193). We compared the disease course of patients with at least 12 months of clinical remission who discontinued infliximab (n = 111) with that of patients who continued scheduled treatment (controls, n = 82). We examined the incidence rates of relapse, hospitalization and colectomy, the comparative effectiveness of different therapeutic strategies after discontinuation, and assessed the rates of response, remission, and adverse effects after infliximab re-initiation. Statistical analyses used time-to-event methods. RESULTS In the entire cohort, 67 patients (34.7%) relapsed during the follow-up period. The incidence rate of relapse was significantly higher after discontinuation (23.3 per 100 person-years) compared with the control group (7.2 per 100 person-years) in univariable analysis (log-rank P < .001; hazard ratio, 3.41; 95% confidence interval, 1.88-6.20) and multivariable analysis (hazard ratio, 3.70; 95% confidence interval, 2.02-6.77). Rates of hospitalization and colectomy did not differ between groups. Thiopurines appeared to be the best treatment option after infliximab discontinuation (incidence of relapse: 15.0 per 100 person-years for thiopurines, 27.4 per 100 person-years for thiopurines plus aminosalicylates, and 31.2 per 100 person-years for aminosalicylates alone; log-rank P = .032). Response was regained in 77.1% of patients and remission in 51.4% of patients who re-initiated infliximab. However, 17.1% had infusion reactions and 17.1% reported other adverse events. CONCLUSIONS In a multinational retrospective cohort study of patients with UC in sustained clinical remission, we associated discontinuation of infliximab with an increased risk of relapse. Treatment re-initiation is effective and safe.

Abstract
INTRODUCTION AND AIMS As inflammatory bowel diseases [IBD] affect female patients almost exclusively during their reproductive age, issues related to fertility, fecundity, pregnancy, delivery, and lactation are of utmost importance. Lack of education and misconceptions regarding the effect of disease and/or treatment on reproductive outcome may lead to voluntary childlessness and/or development of unwanted cervical pathologies which may impact tremendously on patients' welfare and quality of life. The aims of this study were to assess the perspectives of IBD patients on fertility, pregnancy and its outcomes, and lactation, as well as their awareness of human papillomavirus [HPV]-related pathologies and screening for cervical cancer. METHODS This prospective study was performed across nine different Mediterranean IBD centres between 2014 and 2015 and included consecutive female IBD patients between the ages of 16 and 50 years. All patients responded to a questionnaire based on ECCO guidelines. RESULTS A total of 348 IBD female patients with a mean age of 37.4 (standard deviation [SD] ± 2.1) years were recruited; 50% had a diagnosis of ulcerative colitis, 49.4% had Crohn`s disease, and 0.6% patients had a diagnosis of indeterminate colitis [IC]. A significant proportion of patients [ > 60%] were afraid that IBD may lead to a complicated pregnancy and that the disease itself and/or its medications can cause fetal harm. Patients had similar concerns that IBD can be transmitted to their offspring as well as with regard to breastfeeding. Counselling from health care professionals with regard to fertility, pregnancy, and lactation was associated positively with the highest number of pregnancies and inversely with the lowest number of patients who considered voluntary childlessness [p < 0.0001]. Patients with a higher level of education were more likely to get pregnant [p = 0.004]. There was a low uptake of the HPV vaccine. However, there was a reasonably good uptake of cervical cancer screening. CONCLUSION Our study demonstrates that women with IBD have misperceptions about fertility, pregnancy, and health maintenance. We also show that education by physicians has a positive influence. We thus conclude that improved multidisciplinary approaches should be used to educate and implement European guidelines for women with IBD.

Abstract
OBJECTIVE Patients with inflammatory bowel disease (IBD) should be routinely screened for latent tuberculosis (LTB) before starting anti-TNF therapy in order to prevent reactivation of LTB. Besides tuberculin skin test (TST), QuantiFERON-TB Gold In-Tube (QFT-G-IT) has gained wide acceptance as a screening strategy for LTB in IBD, although it may be negatively influenced by the prior use of immunomodulators (IMM) such as azathioprine or methotrexate. This study aimed to assess the impact of IMM on the TST and the QFT-G-IT for LTB screening in IBD patients scheduled for anti-TNF therapy. MATERIAL AND METHODS This observational, prospective, single-center study included consecutive IBD patients scheduled for anti-TNF therapy undergoing on the same day both TST and QFT-G-IT for screening of LTB, between 2008 and 2010. Patients with a prior history of known or suspicious (L)TB receiving (prophylactic) anti-TB therapy were excluded. RESULTS Seventy-five patients were finally included; 28 were treated with thiopurines (IMM group), while 47 (control group) received either 5-aminosalicylic acid (n = 41) or no therapy (newly diagnosed patients, n = 6). Overall, TST and QFT-G-IT were positive in 14 (18.7%) and 16 (21.3%) patients, respectively. There was no statistically significant difference between the two groups regarding the TST (p = 0.761) and QFT-G-IT (0.572) positivity. The overall concordance between the two tests was moderate (kappa = 0.584), being substantial in the IMM group (kappa = 0.700) and moderate in the control group (kappa = 0.498). CONCLUSION These preliminary results suggest that IMM may not have a significant impact on either QFT-G-IT or TST, although larger, prospective studies are certainly warranted.

Abstract
BACKGROUND AND AIMS Extraintestinal manifestations [EIMs] are common in inflammatory bowel disease [IBD]. Data on epidemiology and risk factors of EIMs in IBD patients are limited. The aim of this study was to investigate the prevalence of EIMs in a large cohort of Greek IBD patients and identify risk factors for their development. METHODS The study population consisted of IBD patients, who were followed in eight tertiary Greek hospitals. Demographic and clinical characteristics of patients were analysed. The diagnosis of EIMs was based on standard criteria and on specialist consultation. RESULTS In total, 1860 IBD patients (1001 with Crohn's disease [CD], 859 with ulcerative colitis [UC]) were registered. Among them 615 [33.1%] exhibited at least one EIM; 238 patients [38.6%] developed an EIM before IBD diagnosis. An association between active IBD and presence of an EIM was established in 61.1% of the patients. Arthritic [peripheral arthritis], mucocutaneous [erythema nodosum], and ocular [episcleritis] were the most common manifestations. EIMs were more prevalent in females, patients with CD, smokers [for all p <0.0001], patients with extensive UC [p = 0.007], and patients with a previous appendectomy [p < 0.0001] or a major IBD-related surgery [p = 0.012]. CONCLUSIONS About one-third of Greek IBD patients developed at least one EIM. Of those, more than one-third had their EIM diagnosed before IBD, and in about two-thirds it was related to disease activity. EIMs were more frequently present in females and patients with extensive UC in multivariate analysis.

Abstract
BACKGROUND Currently, there is no standardized protocol for bowel preparation before small bowel capsule endoscopy (SBCE). This study aimed to investigate the effect of simethicone combined with polyethylene glycol (PEG) on the visualization quality (VQ) of the SBCE in patients with or without known or suspected Crohn's disease (CD). METHODS This observational, prospective, single-center study included consecutive patients undergoing a SBCE between 2007 and 2008. Patients received either a standard bowel cleansing preparation of 2 L PEG and 80 mg simethicone orally 12 and 1 h before SBCE respectively (Group A) or only PEG (Group B). VQ, based on scores for luminal bubbles in frames taken from the small intestine, examination completeness, SBCE diagnostic yield, gastric and small bowel transit times were recorded. RESULTS Of the 115 patients finally included (Group A, n=56 and Group B, n=59) the cecum was visualized in 103 (89.6%). Simethicone overall improved the VQ in the proximal [OR: 2.43 (95%CI: 1.08-5.45), P=0.032] but not in the distal bowel segment (P=0.064). Nevertheless, this effect was not observed in patients undergoing SBCE for either known or suspected CD. CONCLUSION Simethicone as an adjunct to PEG for bowel preparation in patients undergoing SBCE significantly improved the VQ in non-CD patients.

Abstract
Amino acid excretion was investigated in 21 rachitic infants and in 22 of their parents. There was (a) increased alpha-amino acid excretion in one-third of the infants a long time after the rickets had healed, (b) an abnormally high excretion of alpha-amino nitrogen and of phosphorus in many of the parents (c) an abnormal pattern of amino acid excretion in all 9 infants tested, and (d) a good correlation between the excretion of individual amino acids by an infant and by its parents. Our findings suggest that in at least some cases of nutritional rickets there is a genetic element which may manifest itself only under adverse environmental conditions.
