Biological pathways that were upregulated in serum from patients with Crohn´s disease were identified based on changes in protein abundance at different time periods preceding diagnosis. RESULTS We identified a panel of 51 protein biomarkers that were predictive of Crohn´s disease within 5 y with an AUROC of 0.76 and a diagnosis within 1 y with an AUROC of 0.87. Based on the proteins included in the panel, imminent development of CD was associated with changes in the complement cascade, lysosomes, innate immune response, and glycosaminoglycan metabolism. Serum antibodies and proteins identified patients who received a diagnosis of ulcerative colitis within 5 y with an AUROC of only 0.56 and within 1 y with an AUROC of 0.72. CONCLUSIONS We identified a panel of serum antibodies and proteins that were predictive of patients who will receive a diagnosis of Crohn´s disease within 5 y with high accuracy. By contrast we did not identify biomarkers associated with future diagnosis of UC. BACKGROUND Plasma of argon was demonstrated to improve protein and cell adhesion on implant surface. On the other hand, increased surface energy and hydrophilicity could potentially amplify the risks of implant surface contamination during clinical phases, risks that have not yet been evaluated in Literature. The aim of the present in vitro study was to verify if Plasma treatment could alter the implant surface characteristics and its ability to remain sterile. MATERIALS AND METHODS Implants from 9 brands were collected (n=11). One implant for each company was used for SEM surface analysis. To perform the microbiological analysis, ten implants from each company were used and randomly split by allocation either in test or control group. To replicate the surgical work flow, both test and control samples were left 60s in clinical environment. Bacterial growth analysis was performed. Optical density at 600nm was measured as readout of bacterial growth and colony forming unit (CFU) after 24h was evaluated. Statistical analysis was performed by using the Wilcoxon Mann Whitney test. A p-value lower than 0.05 was considered significant. BTK inhibitor RESULTS SEM analysis revealed different categories of implant surface roughness. The optical density confirmed a readout of bacterial growth between 4 and 7 with no significant differences within groups. The number of CFU/ml for each measured sample (test and control) was lower than 102 and failed to present significant differences. CONCLUSION Surface activation using plasma of argon did not affect the degree of implant contamination, allowing to maintain a substantial sterility of the implant independently of its morphology. This may allow in the next future the use of bioactivation through plasma of argon to exploit the superhydrophilicity deriving from this biophysical process. Histological subtypes of malignant pleural mesothelioma are a major prognostic indicator and decision denominator for all therapeutic strategies. In ambiguous case a rare transitional [TM) pattern may be diagnosed by pathologists either as epithelioid (EM), biphasic (BM) or sarcomatoid (SM) mesothelioma. The aims of this study were to better characterize the TM subtype from a morphological, immunohistochemical, molecular standpoint; deep learning of pathological slides was applied to this cohort. METHODS A random selection of 49 representative digitalized sections from surgical biopsies of TM were reviewed by 16 panelists. We evaluated BAP1 expression and p16 homozygous deletion [HD]. We conducted a comprehensive integrated transcriptomic analysis. Unsupervised deep learning algorithm was trained to classify tumors. RESULTS The 16 panelists recorded 784 diagnoses on the 49 cases. Whilst Kappa value of 0.42 is moderate, the presence of a TM component was diagnosed in 51%. In 49%, the reviewers classified the lesion as EM in 53%, SM in 33%, or BM in 14%. Median survival was 6.7 months. Loss of BAP1 observed in 44% was less frequent in TM than in EM and BM. p16 HD was higher in TM 73% followed by BM (63%) and SM (46%). RNA sequencing unsupervised clustering analysis showed that TM grouped together and were closer to SM than to EM. Deep learning analysis achieved a 94% accuracy for TM identification CONCLUSION These results demonstrated that TM pattern should be classified in non-epithelioid mesothelioma at minimum as a subgroup of SM type. BACKGROUND The term germline is commonly used to refer to any non-tumor control sample analyzed in tumor-normal paired sequencing experiments. Blood is the most commonly utilized control, and variants found in both tumor and blood are considered germline. However, somatic variants accumulate within an organism from embryogenesis throughout life. The resultant mosaicism is extensive and calls into question the assumption that blood, or any somatic tissue, represents the germline. Misclassification of germline and somatic variants has critical consequences for individual patient care and enormous impact on our healthcare system, given potential screening, counseling, and treatment implications of misidentifying germline variants. METHODS Whole-exome sequencing was performed on six separate specimens from each of two patients with papillary thyroid carcinoma, and three specimens each from eight additional patients forming a validation cohort. Tumor variants were compared to each individual non-tumor control and rmline-somatic designation if these data are to inform clinical decisions and suggests that improved design of controls can overcome current limitations. Glucans are complex polysaccharides consisting of repeated units of d-glucose linked by glycosidic bonds. The nutritional contribution in α-glucans is mainly given by starch and glycogen while in β-glucans by mushrooms, yeasts and whole grains, such as barley and spelt well represented in the Mediterranean Diet. Numerous and extensive studies performed on glucans highlighted their marked anti-tumor, antioxidant and immunomodulatory activity. It has recently been shown that rather than merely being a passive barrier, the intestinal epithelium is an essential modulator of immunity. Indeed, epithelial absorptive enterocytes and mucin secreting goblet cells can produce specific immune modulating factors, driving innate immunity to pathogens as well as preventing autoimmunity. Despite the clear evidence of the effects of glucans on immune system cells, there are only limited data about their effects on immune activity of mucosal intestinal cells strictly related to intestinal barrier integrity. The aim of the study was to evaluate the effects of α and β glucans, alone or in combination with other substances with antioxidant properties, on reactive oxygen species (ROS) levels, on the expression of ROS-generating enzyme DUOX-2 and of the immune modulating factors Tumor Necrosis Factor (TNF-α), Interleukin 1 β (IL-1β) and cyclooxygenase-2 (COX-2) in two intestinal epithelial cells, the enterocyte-like Caco-2 cells and goblet cell-like LS174T.
