Inflammatory bowel diseases affect 0.8% of the Europeans, and are associated with high morbidity, definite mortality and an increasing economic burden. Current diagnostic tools and therapeutics for IBD are unsatisfactory. Development of biomarkers allowing insights into pathogenesis, prognosis and targeted therapy is a major unmet need. This programme addresses that need. IBD-BIOM is a multidisciplinary consortium of leading academic and industrial SME researchers in inflammatory bowel disease, genomics, glycomics, glycoproteomics and activomics. Recent genome-wide association studies performed by IBD-BIOM partners have identified nearly 100 genes associated with IBD, but clinical application of these is so far limited. IBD-BIOM will capitalise on its existing high quality clinical, genetic, biochemical and immunological data and biological samples on over 6000 very well characterised IBD patients and controls by exploiting novel technological approaches made available through the expertise and global leading position of IBD-BIOM partners. These comprise cutting edge epigenetic, glycomic, glycoproteomic and activomic approaches which were all previously reported to be associated with inflammation and disturbances to the immune system. The inclusion of these complementary analyses in the diagnostics of IBD should also facilitate elucidation of pathways through which environmental exposures influence IBD risk and progression. A complex systems biology approach will be used to integrate, interrogate and understand this multidimensional dataset to identify novel early diagnostic and prognostic biomarkers and new targets for therapeutic intervention. The track record of achievement of IBD-BIOM partners coupled to the central and leading positions of the research-intensive SME partners in IBD-BIOM is a strong indication that the ambitions work programme will be achieved and a framework to facilitate swift conversion of research discoveries into commercial products.

In physiological hemostasis a prompt recruitment of platelets on the vessel damage prevents the bleeding by the rapid formation of a platelet plug. Qualitative and/or quantitative platelet defects promote bleeding, whereas the high residual reactivity of platelets in patients on antiplatelet therapies moves forward thromboembolic complications. The biochemical mechanisms of the different phases of platelet activation-adhesion, shape change, release reaction, and aggregation-have been well delineated, whereas their complete translation into laboratory assays has not been so fulfilled. Laboratory tests of platelet function, such as bleeding time, light transmission platelet aggregation, lumiaggregometry, impedance aggregometry on whole blood, and platelet activation investigated by flow cytometry, are traditionally utilized for diagnosing hemostatic disorders and managing patients with platelet and hemostatic defects, but their use is still limited to specialized laboratories. To date, a point-of-care testing (POCT) dedicated to platelet function, using pertinent devices much simpler to use, has now become available (ie, PFA-100, VerifyNow System, Multiplate Electrode Aggregometry [MEA]). POCT includes new methodologies which may be used in critical clinical settings and also in general laboratories because they are rapid and easy to use, employing whole blood without the necessity of sample processing. Actually, these different platelet methodologies for the evaluation of inherited and acquired bleeding disorders and/or for monitoring antiplatelet therapies are spreading and the study of platelet function is strengthening. In this review, well-tried and innovative platelet function tests and their methodological features and clinical applications are considered. © 2015 Paniccia et al. Source

Background Contrast echocardiography improves accuracy and reduces interreader variability on left ventricular (LV) functional analyses in the setting of two-dimensional (2D) echocardiography. The need for contrast imaging using three-dimensional (3D) echocardiography is less defined. The aim of this multicenter study was to define the accuracy and interreader agreement of unenhanced and contrast-enhanced 2D and 3D echocardiography for the assessment of LV volumes and ejection fraction (EF). Methods A multicenter, open-label study was conducted including 63 patients, using intrasubject comparisons to assess the agreement of unenhanced and contrast-enhanced 2D and 3D echocardiography as well as calibrated biplane cine ventriculography with cardiac magnetic resonance for the determination of LV volumes and EF. Each of the imaging techniques used to define LV function was assessed by two independent, off-site readers unaware of the results of the other imaging techniques. Results LV end-systolic and end-diastolic volumes were underestimated by 2D and 3D unenhanced echocardiography compared with cardiac magnetic resonance. Contrast enhancement resulted in similar significant increases in LV volumes on 2D and 3D echocardiography. The mean percentage of interreader variability for LV EF was reduced from 14.3% (95% confidence interval [CI], 11.7%-16.8%) for unenhanced 2D echocardiography and 14.3% (95% CI, 9.7%-18.9%) for unenhanced 3D echocardiography to 8.0% (95% CI, 6.3%-9.7%; P <.001) for contrast-enhanced 2D echocardiography and 7.4% (95% CI, 5.7%-9.1%; P <.01) for contrast-enhanced 3D echocardiography and thus to a similar level as for cardiac magnetic resonance (7.9%; 95% CI, 5.4%-10.5%). A similar effect was observed for interreader variability for LV volumes. Conclusions Contrast administration on 3D echocardiography results in improved determination of LV volumes and reduced interreader variability. The use of 3D echocardiography requires contrast application as much as 2D echocardiography to reduce interreader variability for volumes and EF.

Reconstructions of large lesions or defects often require a bone graft or a bone substitute to promote healing. In common practice the reconstruction of a bone defect is dependent on the site and size of the lesion: in long bones intercalary defects may be managed with Ilizarov technique of bone transport and distraction osteogenesis or the use of a free or pedicled vascularized bone graft, or with Masquelet technique. For cavitary defects the available surgical options include autograft, allograft or xenograft or the use of synthetic scaffolds to promote bone regeneration. In order to promote a faster bone healing tissue engineering proposed the application of enriched graft to fill bone defects. The employment of enriched bone graft has been our choice in the last years to fill contained defects following curettage of a pseudotumoral lesion of bone. We report our clinical experience in terms of safety and success of these procedures at a long-term follow up. Source

Purpose: The aim of this study was to evaluate and report the visual, refractive and aberrometric outcomes of cataract surgery with implantation of the new aspheric Tecnis ZCT toric intraocular lens (IOL) in eyes with low to moderate corneal astigmatism. Methods: We conducted a prospective study of 19 consecutive eyes of 17 patients (mean age: 78 years) with a visually significant cataract and moderate corneal astigmatism [higher than 1 diopter (D)] undergoing cataract surgery with implantation of the aspheric Tecnis ZCT toric IOL (Abbott Medical Optics). Visual, refractive and aberrometric changes were evaluated during a 6-month follow-up. Ocular aberrations as well as IOL rotation were evaluated by means of the OPD-Station II (Nidek). Results: The six-month postoperative spherical equivalent and power vector components of the refractive cylinder were within ±0.50 D in all eyes (100%). Postoperative logMAR uncorrected and corrected distance visual acuities (UDVA/CDVA) were 0.1 (about 20/25) or better in almost all eyes (94.74%). The mean logMAR CDVA improved significantly from 0.41 ± 0.23 to 0.02 ± 0.05 (p < 0.01). No significant changes were found in corneal astigmatism (p = 0.73). The mean IOL rotation was 3.33 ± 1.94°. This parameter did not correlate with higher-order aberrations (r = -0.09, p = 0.73). A significant improvement in the Strehl ratio was also observed (p < 0.01), which was consistent with the significant reduction in higher-order aberrations (p = 0.02). Conclusion: Cataract surgery with implantation of the aspheric Tecnis ZCT IOL is a predictable and effective procedure for visual rehabilitation in eyes with cataract and low to moderate corneal astigmatism, providing an excellent postoperative ocular optical quality. © 2013 S.
