AIMTo define the role of small-bowel transit time in the detection rate of significant small-bowel ***-bowel capsule endoscopy records, prospectively collected from 30 participating centers in the Lombardy Registry from October 2011 to December 2013, were included in the study if the clinical indication was obscure gastrointestinal bleeding and the capsule reached the cecum. Based on capsule findings, we created two groups: P2 (significant findings) and P0-1 (normal/negligible findings). Groups were compared for age, gender, small-bowel transit time, type of instrument, modality of capsule performance (outpatients vs inpatients), bowel cleanliness, and center *** retrieved and scrutinized 1,433 out of 2,295 capsule endoscopy records (62.4%) fulfilling the inclusion criteria. Patients were 67 ± 15 years old, and 815 (57%) were males. In comparison with patients in the P0-1 group, those in the P2 group (n = 776, 54%) were older (P < 0.0001), had a longer small-bowel transit time (P = 0.0015), and were more frequently examined in low-volume centers (P < 0.001). Age and small-bowel transit time were correlated (P < 0.001), with age as the sole independent predictor on multivariable analysis. Findings of the P2 group were artero-venous malformations (54.5%), inflammatory (23.6%) and protruding (10.4%) lesions, and luminal blood (11.5%).CONCLUSIONIn this selected, prospectively collected cohort of small-bowel capsule endoscopy performed for obscure gastrointestinal bleeding, a longer small-bowel transit time was associated with a higher detection rate of significant lesions, along with age and a low center volume, with age serving as an independent predictor.

In the latest issue of Nature Immunology,Piccolo et al.1 elegantly explored the effect of coexisting interferon-γ(IFN-γ)and interleukin 4(IL-4)antagonistic signals on macrophage transcriptional and epigenetic profiles and,interestingly,identified a plastic cross-talk as opposed to mutually exclusive programs between M1 and M2 polarized *** results support the fascinating hypothesis that transcriptional and epigenetic reprogramming overcame genetics to drive the evolution of eukaryotic organisms.A rapid reshaping of chromatin acetylation redirected the expression of hundreds of genes under the control of a few transcription factors in response to two coexisting but opposing signals that indicated inflammation and its resolution simultaneously.

Anna Institute Regional Center for Serious Brain Injuries Crotone Italy

The aged population is constantly growing, thus fostering an increase in age-dependent diseases. Among these, diabetic retinopathy (DR) along with age-related macular degeneration entails progressive vision loss. Since such conditions are associated with the proliferation of novel vessels, their pharmacotherapeutic management consists of the intravitreal injection of anti-vascular endothelial growth factor drugs, able to hinder the driving of vascular proliferation prompted by vascular endothelial growth factor. The humanized anti-vascular endothelial growth factor monoclonal antibody ranibizumab provided evidence for efficacy in several trials, hence earning approval by the US Food and Drug Administration for therapeutic use in all the stages of DR. Due to the lack of epidemiologic and pharmacoeconomic evaluation in the local Calabria Region context, the present retrospective observational study focused on prevalence of DR and age-related macular degeneration, treatment and cost of therapy with ranibizumab in 870 patients arriving to clinical observation at the "Mater Domini” University Hospital in Calabria, Italy from January 2014 to June 2017. Data were extracted from the database of ophthalmology ward and subjected to statistical analysis. The results suggest that the most frequent retinal diseases are age-related macular degeneration and DR and that the use of ranibizumab has been decreasing over the 4-year study period together with the associated cost per patient which was similar for both disorders. Therefore, appropriateness of treatment with drugs other than ranibizumab needs to be assessed in this setting and deep monitoring of pharmacologic treatment for retinal diseases is necessary to prevent or delay visual acuity decrease and complete vision loss. Study procedures were performed in accordance with the "Mater Domini” University Hospital ethical standards of the responsible committee on human experimentation.

This study investigates the degradation behavior of three distinct Fe-based alloys immersed in three pseudo-physiological *** alloys,which have varied Mn and C contents,include a commercially available Fe-0.15C alloy,namely Fe–C,and two newly developed alloys,that is Fe–5Mn-0.2C(namely Fe–5Mn)and Fe–18Mn-0.6C(namely Fe–18Mn).The aim was to understand the effect of alloying elements and the testing solution on the in-vitro degradation behavior of these Fe-based *** immersion degradation and potentiodynamic corrosion tests were carried out using three pseudo-physiological solutions with albumin supply,that is modified Hanks’saline solution(MHSS),phosphate buffered saline solution(PBS),and sodium chloride solution(NaCl).After two weeks of static immersion,the results revealed that Fe–5Mn,characterized by a mixture of ferrite and martensite,showed the highest degradation rate,while Fe–C,composed solely of ferrite,showed the lowest rate of *** predominant degradation products in MHSS and PBS were phosphates and *** PBS,these products formed a remarkably stable protective layer on the surface,contributing to the lowest degradation *** contrast,porous hydroxides appeared as the main degradation products for samples immersed in NaCl solution,leading to the highest degradation *** results provided important insights into the customization of Fe–Mn–C alloys for a range of biomedical applications,meeting a variety of clinical requirements,and highlighting the considerable potential of Fe–Mn–C alloys for biomedical applications.

Advances in medical decision support systems for diagnosis of acute graft-versus-host disease: molecular and computational intelligence joint approaches

Frontiers in Biology 2011年第4期6卷 263-273页

Acute graft-versus-host disease (aGVHD) is a serious systemic complication of allogeneic hematopoietic stemcell transplantation (HSCT) causing considerable morbidity and mortality. Acute GVHD occurs when alloreactivedonor-derived T cells recognize host-recipient antigens as foreign. These trigger a complex multiphase process thatultimately results in apoptotic injury in target organs. The early events leading to GVHD seem to occur very soon,presumably within hours from the graft infusion. Therefore, when the first signs of aGVHD clinically manifest, thedisease has been ongoing for several days at the cellular level, and the inflammatory cytokine cascade is fully ***, it comes as no surprise that progress in treatment based on clinical diagnosis of aGVHD has been limited in the past30 years. It is likely that a pre-emptive strategy using systemic high-dose corticosteroids as early as possible couldimprove the outcome of aGVHD. Due to the deleterious effects of such treatment particularly in terms of infection riskposed by systemic steroid administration in a population that is already immune-suppressed, it is critical to identifybiomarker signatures for approaching this very complex task. Some research groups have begun addressing this issuethrough molecular and proteomic analyses, combining these approaches with computational intelligence techniques,with the specific aim of facilitating the identification of diagnostic biomarkers in aGVHD. In this review, we focus on theaGVHD scenario and on the more recent *** also attempt to give an overview of the classical and noveltechniques proposed as medical decision support system for the diagnosis of GVHD.
