RESUMEN
BACKGROUND: Telemonitoring is not consistently superior to standard care for inflammatory bowel disease (IBD), yet non-inferiority may be an acceptable outcome if remote care is more efficient. OBJECTIVE: To compare the remission time and quality of life of patients with an active IBD controlled by standard care or through the TECCU App (Telemonitoring of Crohn´s Disease and Ulcerative Colitis). METHODS: A 2-arm, randomized, multicentre trial with a non-inferiority design was performed at 24 Spanish hospitals on adult patients with IBD who initiated immunosuppressant or biological therapy. Patients were randomized into telemonitoring (G_TECCU) or standard care groups (G_Control). The follow-up schedule was based on telemonitoring contacts through the TECCU App in G_TECCU, and on in-person visits and telephone calls in G_Control, as in clinical practice. In both groups, treatment was adjusted according to the evolution of disease activity and medication adherence, which were measured through specific indices and biological markers at each check-up. The primary outcome was time in remission after 12-weeks, with quality of life, medication adherence, adverse events and patient satisfaction as secondary outcomes. RESULTS: Of 169 patients enrolled, 158 were randomized, and 150 were analyzed per protocol: telemonitoring (n=71); control (n=79). After 12-week, the time in clinical remission was not inferior after telemonitoring (4.20 ±3.73 weeks) to that in the controls (4.32 ±3.28 weeks), with a mean difference between arms of -0.12 weeks (95% CI -1.25-,1.01), non-inferiority p=0.017). The mean reduction of CRP values was -15.40 mg/L (SD=90.15, P =0.195) in G_TECCU and -13.16 mg/L (SD=54.61, P =0.053) in G_control, without significant differences between the two arms (P=.726). Similarly, the mean improvement of FC levels was 832.3 mg/L (SD=1825.0, P=.003) in G_TECCU and 1073.5 mg/L in G_Control (SD=3105.7, P=.03), but differences were not significant (P=.965). Quality of life improved in both groups, with a mean rise in the IBDQ-9 score of 13.44 points in G_TECCU (SD=19.1; P<.001) and 18.23 points [SD=22.9]; P=.001) in G_Control. Moreover, the proportion of patients who adhered to their medication rose significantly from 35.2% (25/71) to 67.6% (48/71) in G_TECCU (P=.001) and from 45.6% (36/79) to 73.4% (58/79) in G_Control (P=.001). Satisfaction remained stable around 90%, although non-inferiority was not demonstrated for secondary outcomes. CONCLUSIONS: Telemonitoring patients with active IBD is not inferior to standard care to achieve and maintain short-term remission. TECCU may be an alternative follow-up tool if the improved health outcomes and costs are confirmed in the long-term. CLINICALTRIAL: The trial is registered at ClinicalTrials.gov with the identifier NCT06031038; https://classic.clinicaltrials.gov/ct2/show/NCT06031038. INTERNATIONAL REGISTERED REPORT: RR2-10.2196/resprot.9639.
RESUMEN
BACKGROUND: Ulcerative proctitis (UP) can have a milder, less aggressive course than left-sided colitis or extensive colitis. Therefore, immunosuppressants tend to be used less in patients with this condition. Evidence, however, is scarce because these patients are excluded from randomised controlled clinical trials. Our aim was to describe the characteristics of patients with refractory UP and their disease-related complications, and to identify the need for immunosuppressive therapies. METHODS: We identified patients with UP from the prospective ENEIDA registry sponsored by the GETECCU. We evaluated socio-demographic data and complications associated with immunosuppression. We defined immunosuppression as the use of immunomodulators, biologics and/or small molecules. We used logistic regression to identify factors associated with immunosuppressive therapy. RESULTS: From a total of 34,716 patients with ulcerative colitis, we identified 6281 (18.1%) with UP; mean ± SD age 53 ± 15 years, average disease duration of 12 ± 9 years. Immunosuppression was prescribed in 11% of patients, 4.2% needed one biologic agent and 1% needed two; 2% of patients required hospitalisation, and 0.5% underwent panproctocolectomy or subtotal colectomy. We identified 0.2% colorectal tumours and 5% extracolonic tumours. Patients with polyarthritis (OR 3.56, 95% CI 1.86-6.69; p < 0.001) required immunosuppressants. CONCLUSIONS: Among patients with refractory UP, 11% required immunosuppressant therapy, and 4.2% required at least one biologic agent.

Markers that allow for the selection of tailored treatments for individual patients with inflammatory bowel diseases (IBD) are yet to be identified. Our aim was to describe trends in real-life treatment usage. For this purpose, patients from the ENEIDA registry who received their first targeted IBD treatment (biologics or tofacitinib) between 2015 and 2021 were included. A subsequent analysis with Machine Learning models was performed. The study included 10,009 patients [71% with Crohn's disease (CD) and 29% with ulcerative colitis (UC)]. In CD, anti-TNF (predominantly adalimumab) were the main agents in the 1st line of treatment (LoT), although their use declined over time. In UC, anti-TNF (mainly infliximab) use was predominant in 1st LoT, remaining stable over time. Ustekinumab and vedolizumab were the most prescribed drugs in 2nd and 3rd LoT in CD and UC, respectively. Overall, the use of biosimilars increased over time. Machine Learning failed to identify a model capable of predicting treatment patterns. In conclusion, drug positioning is different in CD and UC. Anti-TNF were the most used drugs in IBD 1st LoT, being adalimumab predominant in CD and infliximab in UC. Ustekinumab and vedolizumab have gained importance in CD and UC, respectively. The approval of biosimilars had a significant impact on treatment.
RESUMEN
INTRODUCTION: Risk factors for developing pancreatitis due to thiopurines in patients with inflammatory bowel disease (IBD) are not clearly identified. Our aim was to evaluate the predictive pharmacogenetic risk of pancreatitis in IBD patients treated with thiopurines. METHODS: We conducted an observational pharmacogenetic study of acute pancreatitis events in a cohort study of IBD patients treated with thiopurines from the prospectively maintained ENEIDA registry biobank of GETECCU. Samples were obtained and the CASR, CEL, CFTR, CDLN2, CTRC, SPINK1, CPA1, and PRSS1 genes, selected based on their known association with pancreatitis, were fully sequenced. RESULTS: Ninety-five cases and 105 controls were enrolled; a total of 57% were women. Median age at pancreatitis diagnosis was 39 years. We identified 81 benign variants (50 in cases and 67 in controls) and a total of 35 distinct rare pathogenic and unknown significance variants (10 in CEL, 21 in CFTR, 1 in CDLN2, and 3 in CPA1). None of the cases or controls carried pancreatitis-predisposing variants within the CASR, CPA1, PRSS1, and SPINK1 genes, nor a pathogenic CFTR mutation. Four different variants of unknown significance were detected in the CDLN and CPA1 genes; one of them was in the CDLN gene in a single patient with pancreatitis and 3 in the CPA1 gene in 5 controls. After the analysis of the variants detected, no significant differences were observed between cases and controls. CONCLUSION: In patients with IBD, genes known to cause pancreatitis seem not to be involved in thiopurine-related pancreatitis onset.

Sea fennel and seaside arrowgrass are two abundant but underutilized halophytes along the Atlantic and Mediterranean coasts. This study investigated the antioxidant capacity and the potential antihypertensive (Angiotensin Converting Enzyme I, ACE-I inhibition), hypoglycaemic (Dipeptidyl Peptidase IV, DPP-IV inhibition), and nootropic (Prolyl Endopeptidase, PEP inhibition) activity of their polyphenol extracts. They had a high phenol content (21-24 mEq GA/g), antioxidant capacity evaluated using the ABTS (17-2 mg ascorbic acid/g) and FRAP (170-270 mM Mohr's salt/g) assays, and effective ACE-inhibiting properties (80-90% inhibiting activity at final concentration of 0.5 mg/mL). Additionally, the sea fennel extract displayed high DPP-IV inhibitory capacity (73% at 1 mg/mL), while the seaside arrowgrass extract exhibited potent Prolyl endopeptidase inhibitory capacity (75% at 1 mg/mL). Fractionation by HPLC concentrated the bioactive molecules in two fractions, for which the composition was analyzed by LC-MS/MS. Different chlorogenic acids seemed to play an important role in the bioactivity of sea fennel extract, and different flavonoids, mainly apigenin, luteolin and chrysoeriol, in the bioactivity of the seaside arrowgrass extract. Given their potential health benefits, these extracts could serve as valuable bioactive ingredients and could potentially encourage the cultivation of these species in regions where traditional crops face challenges in growth.
RESUMEN
As the patents for biologic originator drugs expire, biosimilars are emerging as cost-effective alternatives within healthcare systems. Addressing various challenges in the clinical management of inflammatory bowel disease (IBD) remains crucial. To shed light on physicians' current knowledge, beliefs, practical approaches, and concerns related to biosimilar adoption-whether initiating a biosimilar, transitioning from an originator to a biosimilar, or switching between biosimilars (including multiple switches and reverse switching)-a global survey was conducted. Fifteen physicians with expertise in the field of IBD from 13 countries attended a virtual international consensus meeting to develop practical guidance regarding biosimilar adoption worldwide, considering the survey results. This consensus centered on 10 key statements covering biosimilar effectiveness, safety, indications, rationale, multiple switches, therapeutic drug monitoring of biosimilars, non-medical switching, and future perspectives. Ultimately, the consensus affirmed that biosimilars are equally effective and safe when compared to originator drugs. They are considered suitable for both biologic-naïve patients and those who have previously been treated with originator drugs, with cost reduction being the primary motivation for transitioning from an originator drug to a biosimilar.
RESUMEN
PROBLEM: Recurrent pregnancy loss (RPL) and recurrent implantation failure (RIF) represent distinct clinical conditions with established definitions, both of which have been linked to an underlying pro-inflammatory state. This study aimed to explore the levels of monocytic-myeloid-derived suppressor cells (M-MDSCs) and regulatory T cells (TReg ) in a cohort of RPL and RIF women and their potential contribution to RPL and RIF. METHOD OF STUDY: One hundred and eight non-pregnant women were evaluated: 40 RPL, 41 RIF, and 27 fertile healthy controls (HC). A multiparametric flow cytometry approach was utilized to measure and quantify the frequency of M-MDSCs and TReg cells. Cytokine levels in plasma samples were evaluated through a multiplex assay. M-MDSCs levels were significantly higher in RPL and RIF patients compared to HC. RESULTS: M-MDSCs levels were significantly higher in RPL (9.4% [7-11.6]) and RIF (8.1% [5.9-11.6]) patients compared to HC (6% [4.2-7.6]). An optimal cut-off of 6.1% for M-MDSCs disclosed a sensitivity of 75.6% and 89.7% and a specificity of 57.7% and 57.7% in RIF and RPL groups, respectively. A significant negative correlation was observed between M-MDSCs and TReg (p = .002, r = -.51). CONCLUSIONS: Our preliminary data allowed us to build a predictive model that may aid as a potential diagnostic tool in the clinic. These findings could provide a better understanding of these pathologies and a better definition of patients that could benefit from personalized treatments to promote pregnancy. Additional exploration and confirmation in distinct study groups are needed to fully assess the diagnostic capabilities of this biomarker.

Less than 5% of patients with liver cirrhosis (LC) with portal hypertension (PH) develop atypical shunt (in regions other than the esophagus or the stomach). Within this group are varices associated with a stoma, for example the ones associated with an uretero-ileostomy which are infrequent. They are a diagnostic and therapeutic challenge, as they can cause hemorrhages due to PH. We present a clinical case about stoma varicose bleeding as the latest guidelines for the management of PH do not mention them or their treatment due to their low incidence.

Genomic Instability (GI) is a transversal phenomenon shared by several tumor types that provide both prognostic and predictive information. In the context of high-grade serous ovarian cancer (HGSOC), response to DNA-damaging agents such as platinum-based and poly(ADP-ribose) polymerase inhibitors (PARPi) has been closely linked to deficiencies in the DNA repair machinery by homologous recombination repair (HRR) and GI. In this study, we have developed the Scarface score, an integrative algorithm based on genomic and transcriptomic data obtained from the NGS analysis of a prospective GEICO cohort of 190 formalin-fixed paraffin-embedded (FFPE) tumor samples from patients diagnosed with HGSOC with a median follow up of 31.03 months (5.87-159.27 months). In the first step, three single-source models, including the SNP-based model (accuracy = 0.8077), analyzing 8 SNPs distributed along the genome; the GI-based model (accuracy = 0.9038) interrogating 28 parameters of GI; and the HTG-based model (accuracy = 0.8077), evaluating the expression of 7 genes related with tumor biology; were proved to predict response. Then, an ensemble model called the Scarface score was found to predict response to DNA-damaging agents with an accuracy of 0.9615 and a kappa index of 0.9128 (p < 0.0001). The Scarface Score approaches the routine establishment of GI in the clinical setting, enabling its incorporation as a predictive and prognostic tool in the management of HGSOC.
RESUMEN
Colonic impaction due to a fecaloma is a very frequent complication in patients with chronic constipation. Most cases respond to conservative measures such as digital disimpaction or treatment with oral laxatives and enemas. However, in some cases fecalomas could be refractory to these treatments requiring aggressive measures such as endoscopic or surgical removal. Even more, there are a few cases of death reported as a complication of a fecaloma refractory to usual treatments. We report, for the first time, a case of a patient with a huge fecaloma refractory to oral laxative and enemas resolved conservatively with a single irrigation of a carbonated soft drink through a rectal probe.

Introduction: The internet is emerging as a source of information for patients with inflammatory bowel disease (IBD). However, it is not always reliable and may cause anxiety. We aim to assess patients' information habits and patients' and professionals' perceptions of a national website integrated as an educational resource for the IBD unit. Methods: Patients aged 18-65 years, comfortable with the internet, and attending follow-ups at participating IBD units (March-June 2019) and their professionals were invited to evaluate a recommended website through an online survey. Results: Three hundred eighty-nine patients and 95 professionals completed the survey. The internet (n = 109; 27.4%) was the second preferred source of information after the health care team (n = 229; 57.5%). Eighty percent of patients searched the internet for information on their disease and 28.6% did so at least once a week (n = 114), especially newly diagnosed ones (<2 years). Patients valued a website recommended by their professional (n = 379; 95.2%) and endorsed by the National Working Group (n = 377; 94.7%). They would attend online educational initiatives on the website (n = 279; 70.1%) and complete periodical surveys to improve its usefulness (n = 338; 84.9%). According to IBD professionals, this type of website is the best patient source of supplementary information (n = 76; 80%) and they "prescribe" it to most patients (67.0 ± 25.2%), especially the newly diagnosed patients (52.7 ± 26.5%). It effectively integrates routine face-to-face education (n = 95; 100%). Conclusions: Patients of IBD units, especially newly diagnosed ones, appreciate a trusted e-Health resource to back up professional information. The favorable opinion of patients and professionals will allow its use in training interventions.

BACKGROUND: Anti-TNF agents are the only effective biological agents for the prevention of postoperative recurrence (POR) in Crohn's disease (CD). However, they are contraindicated or have been shown to fail in some patients. Although ustekinumab and vedolizumab were licensed for CD some years ago, data in this setting are scarce. METHODS: All CD patients in whom ustekinumab or vedolizumab was prescribed for the prevention of POR within three months of ileocolonic resection with anastomosis were identified from the ENEIDA registry. The development of endoscopic, clinical and surgical POR was registered. RESULTS: Forty patients were treated for the prevention of POR with ustekinumab and 25 were treated with vedolizumab. Eighty per cent had at least one risk factor for POR (prior resections, active smoking, perianal disease or penetrating disease behaviour). All the patients had been exposed to anti-TNF therapy. After a median follow-up of 17 and 26 months, the cumulative probability of clinical POR at 12 months after surgery was 32% and 30% for ustekinumab and vedolizumab, respectively. Endoscopic assessment within the first 18 months after surgery was available for 80% of the patients on ustekinumab and 70% for those on vedolizumab. The rate of endoscopic POR was 42% for ustekinumab and 40% for vedolizumab. One patient treated with ustekinumab and two with vedolizumab underwent a new intestinal resection. CONCLUSIONS: Ustekinumab and vedolizumab seem to be effective in the prevention of POR in patients at high risk. Our results warrant controlled trials comparing these drugs with conventional therapies.

There is currently much activity toward the integration of mid-infrared semiconductor lasers on Si substrates for developing a variety of smart, compact, sensors based on Si-photonics integrated circuits. We review this rapidly-evolving research field, focusing on the epitaxial integration of antimonide lasers, the only technology covering the whole mid-to-far-infrared spectral range. We explain how a dedicated molecular-beam epitaxy strategy allows for achieving high-performance GaSb-based diode lasers, InAs/AlSb quantum cascade lasers, and InAs/GaInSb interband cascade lasers by direct growth on on-axis (001)Si substrates, whereas GaAs-on-Si or GaSb-on-Si layers grown by metal-organic vapor phase epitaxy in large capability epitaxy tools are suitable templates for antimonide laser overgrowth. We also show that etching the facets of antimonide lasers grown on Si is a viable approach in view of photonic integrated circuits. Remarkably, this review shows that while diode lasers are sensitive to residual crystal defects, the quantum cascade and interband cascade lasers grown on Si exhibit performances comparable to those of similar devices grown on their native substrates, due to their particular band structures and radiative recombination channels. Long device lifetimes have been extrapolated for interband cascade lasers. Finally, routes to be further explored are also presented.
RESUMEN
This study aims to determine the potential antioxidant, antihypertensive, hypoglycaemic and nootropic activity of a purified polyphenolic extract from the halophyte ice plant (Mesembryanthemum crystallinum). The ice plant extract showed good antioxidant activity measured by DPPH, ORAC, TEAC, FRAP and ferrous ion chelating activity. Moreover, the extract showed potent ACE, DPP-IV and PEP-inhibitory activity (90.5%, 98.6% and 73.1%, respectively, at a final concentration of 1 mg/mL). The extract was fractionated and the fraction with the highest content of total phenolic compounds showed the highest bioactivity, suggesting that polyphenols could be mainly responsible for the abovementioned activities. The tentative polyphenol identification by HPLC-ESI-QTOF-MS in this fraction revealed that flavones (>65%) are the major group, with apigenin (38%) predominating, followed by diosmin (17.7%) and luteolin (11.9%). They could presumably be the main elements responsible for the enzymatic inhibition activity. Additionally, 4-hydroxybenzoic acid, p-coumaric acid and a hydroxycinnamic acid derivative (2-O-(p-cumaroyl)-l-malic acid) were found in the extract. To our knowledge, this is the first time that some of these activities have been reported for halophyte extracts.
RESUMEN
BACKGROUND: Optimal golimumab concentration thresholds for important outcomes during maintenance are lacking. AIMS: To investigate the association of golimumab trough concentrations during maintenance with key outcomes, including endoscopic and histologic remission, and long-term event-free persistence with golimumab, in patients with UC. METHODS: This multi-centre, cross-sectional study included patients with UC on golimumab maintenance recruited either in remission or during a flare. Colonoscopy was scheduled, and study-specific rectocolonic biopsies were taken for blind central histologic reading. Samples for golimumab trough concentrations were collected close to colonoscopy. RESULTS: Fifty-two patients were included. Median golimumab trough concentrations (µg/ml) were significantly higher in patients who had clinical remission (2.01 vs. 0.72, p = 0.047), combined clinical-biochemical remission (PMS ≤2 + faecal calprotectin <250 µg/g) (2.21 vs. 1.47, p = 0.041), endoscopic healing (Mayo endoscopic subscore 0) (2.52 vs. 1.47, p = 0.003), histologic remission (Geboes index ≤2.0) (2.33 vs. 1.50, p = 0.02) and disease clearance (clinical remission endoscopic healing + histologic remission) (2.52 vs. 1.70, p = 0.009), compared with those not meeting these criteria. Golimumab concentrations were significantly higher in patients who avoided golimumab dose escalation/discontinuation during follow-up (2.24 vs. 0.98, p = 0.012). Receiver-operating characteristic analyses identified golimumab thresholds [area under the curve] of 0.85 [0.76], 1.90 [0.76], 2.29 [0.75], 1.79 [0.68], 2.29 [0.72] and 1.56 [0.71] µg/ml as associated with clinical remission, combined remission, endoscopic healing, histologic remission, disease clearance and long-term event-free persistence with golimumab, respectively. CONCLUSIONS: Golimumab trough concentrations during maintenance are associated with favourable treatment outcomes including endoscopic healing, histologic remission and long-term persistence on golimumab. We identified the optimal golimumab thresholds most closely associated with key outcomes.

BACKGROUND AND AIMS: Crohn's disease [CD] can develop penetrating complications at any time during the disease course. Enterocutaneous fistulae [ECF] are disease-related complications with an important impact on quality of life. Our aim was to describe the outcomes of this complication, including its medical and/or surgical management and their temporal trends. The primary endpoint was fistula closure, defined as the absence of drainage, with no new abscess or surgery, over the preceding 6 months. METHODS: Clinical information from all adult patients with CD and at least one ECF-excluding perianal fistulae-were identified from the prospectively-maintained ENEIDA registry. All additional information regarding treatment for this complication was retrospectively reviewed. RESULTS: A total of 301 ECF in 286 patients [January 1970-September 2020] were analysed out of 30 088 records. These lesions were mostly located in the ileum [67%] and they had a median of one external opening [range 1-10]. After a median follow-up of 146 months (interquartile range [IQR], 69-233), 69% of patients underwent surgery. Fistula closure was achieved in 84%, mostly after surgery, and fistula recurrence was uncommon [13%]. Spontaneous and low-output fistulae were associated with higher closure rates (hazard ratio [HR] 1.51, 95% confidence interval [CI] 1.17-1.93, pâ =â 0.001, and HR 1.49, 95% CI 1.07-2.06, pâ =â 0.03, respectively); this was obtained more frequently with medical therapy since biologics have been available. CONCLUSIONS: ECF complicating CD are rare but entail a high burden of medical and surgical resources. Closure rates are high, usually after surgery, and fistula recurrence is uncommon. A significant proportion of patients receiving medical therapy can achieve fistula closure.

BACKGROUND AND OBJECTIVE: The emergence of highly tolerable, effective, and shorter duration direct-acting antivirals (DAAs) regimens offers the opportunity to simplify hepatitis C virus management but medical costs are unknown. Thus, we aimed to determine the direct medical costs associated with a combo-simplified strategy (one-step diagnosis and low monitoring) to manage HCV infection within an 8-week glecaprevir/pibrentasvir (GLE/PIB) regimen in clinical practice in Spain. PATIENTS AND METHODS: Healthcare resources and clinical data were collected retrospectively from medical charts of 101 eligible patients at 11 hospitals. Participants were adult, treatment naïve subjects with HCV infection without cirrhosis in whom a combo-simplified strategy with GLE/PIB for 8 weeks were programmed between Apr-2018 and Nov-2018. RESULTS: The GLE/PIB effectiveness was 100% (CI95%: 96.2-100%) in the mITT population and 94.1% (CI95%: 87.5-97.8%) in the ITT population. Three subjects discontinued the combo-simplified strategy prematurely, none of them due to safety reasons. Five subjects reported 8 adverse events, all of mild-moderate intensity. Combo-simplified strategy mean direct costs were 754.35±103.60 compared to 1689.42 and 2007.89 of a theoretical 12-week treatment with 4 or 5 monitoring visits, respectively; and 1370.95 and 1689.42 of a theoretical 8-week with 3 or 4 monitoring visits, respectively. Only 4.9% of the subjects used unexpected health care resources. CONCLUSIONS: 8-week treatment with GLE/PIB combined with a combo simplified strategy in real-life offers substantial cost savings without affecting the effectiveness and safety compared to traditional approaches.

BACKGROUND: Meckel's diverticulum is a common asymptomatic congenital gastrointestinal anomaly. However, its presentation as an inverted Meckel's diverticulum is a rare complication, of which few cases have been reported in the literature. CASE SUMMARY: Here, we report the case of a 33-year-old man with iron deficiency anemia without manifestation of gastrointestinal bleeding. An upper gastrointestinal endoscopy and total colonoscopy were performed, but no abnormalities were found within the observed area. Finally, a capsule endoscopy was performed and offered us a clue to subsequently confirm the diagnosis of inverted Meckel's diverticulum via computed tomography scan. Laparoscopic intestinal resection surgery was performed. The final pathology report described a Meckel's diverticulum. CONCLUSION: Since inverted Meckel's diverticulum is an uncommon disease and its clinical presentation is not specific, it may go undetected by capsule endoscopy. Successful diagnosis and treatment of this disease requires a high index of clinical suspicion.

BACKGROUND: Because of their specific and biologically relevant cargo, urine extracellular vesicles (EVs) constitute a valuable source of potential non-invasive biomarkers that could support the clinical decision-making to improve the management of prostate cancer (PCa) patients. Different EV isolation methods differ in terms of complexity and yield, conditioning, as consequence, the analytical result. METHODS: The aim of this study was to compare three different isolation methods for urine EVs: ultracentrifugation (UC), size exclusion chromatography (SEC), and a commercial kit (Exolute® Urine Kit). Urine samples were collected from 6 PCa patients and 4 healthy donors. After filtered through 0.22 µm filters, urine was divided in 3 equal volumes to perform EVs isolation with each of the three approaches. Isolated EVs were characterized by spectrophotometric protein quantification, nanoparticle tracking analysis, transmission electron microscopy, AlphaScreen Technology, and whole miRNA Transcriptome. RESULTS: Our results showed that UC and SEC provided better results in terms of EVs yield and purity than Exolute®, non-significant differences were observed in terms of EV-size. Interestingly, luminescent AlphaScreen assay demonstrated a significant enrichment of CD9 and CD63 positive microvesicles in SEC and UC methods compared with Exolute®. This heterogeneity was also demonstrated in terms of miRNA content indicating that the best correlation was observed between UC and SEC. CONCLUSIONS: Our study highlights the importance of standardizing the urine EV isolation methods to guaranty the analytical reproducibility necessary for their implementation in a clinical setting.

BACKGROUND AIMS: Current therapeutic goals in ulcerative colitis (UC) include clinical and endoscopic remission, named mucosal healing (MH). Despite MH, a proportion of patients suffer a clinical relapse, which has been related to histological inflammation. We aimed to identify which histopathological features or histopathological index cut-off was associated with endoscopic relapse (ER) in UC patients with MH. METHODS: Retrospective analysis of UC patients who underwent surveillance colonoscopy showing complete MH (endoscopic Mayo subscore=0) with random biopsies, and at least one more endoscopy along the follow-up. After a consensus meeting, expert pathologist performed histological assessment according to Simplified Geboes Score (SGS), Nancy Index (NI) and Robarts Histopathological Index (RHI). Other histopathological features were also evaluated. Patients were followed until ER or last endoscopy performed showing persistence of MH. RESULTS: A total of 95 patients (150 colonoscopies) were included. After mean follow-up of 31.2 months (SD 21.7), 33 patients (34.7%) suffered ER. Neutrophils in lamina propria (OR 2.6; P = 0.037), within the epithelium (OR 2.6; P = 0.03), SGS ≥3.1 (OR 2.6; P = 0.037), NI ≥2 (OR 2.6; P = 0.03) and RHI ≥5 (OR 2.6; P = 0.037) were associated with ER in univariate analysis. In multivariate analysis, eosinophils in the lamina propria (HR 2.5; P = 0.01) and clinical remission<12 months (HR 3.2; P = 0.002) were associated with ER. CONCLUSIONS: Histopathological findings in UC patients who have achieved endoscopic MH may predict ER. Standardized histopathology reports according to the presence of neutrophils, eosinophils or to defined cut-off of validated histopathologic indexes may represent a useful tool to predict ER and should be considered at therapeutic and surveillance decision process.
