n of patients at risk remains difficult. A multidimensional focus is probably needed to reduce risks.While a minority of patients with ulcerative colitis has primary sclerosing cholangitis (PSC), a significant proportion of patients with PSC have ulcerative colitis. The activity of PSC is usually not commensurate with the degree of concomitant colonic inflammation. Moreover, up to one-third of patients with a history of ulcerative colitis may paradoxically experience worsening of their colonic inflammation despite receiving immunosuppression after liver transplantation for PSC. There is a dearth of data pertaining to the management of ulcerative colitis in this post-transplantation patient population. We hereby delineate the case of a patient with severe refractory ulcerative colitis in the aftermath of liver transplantation due to PSC who eventually responded to oral vancomycin after failure of biologic therapy. Since current data implicate that patients with ulcerative colitis and PSC often present with distinct alterations of their colonic microbiome, oral vancomycin may be conjectured to demonstrate a therapeutic role. In this article, the review of literature suggests that oral vancomycin might indeed be an effective substitute in patients in whom the uptake of biologic agents may be challenging owing to their already immunosuppressed status.The objective of this paper is to investigate the possibility and efficacy of recurrent laryngeal nerve repair by transplantation of co-cultured Schwann cells and neural stem cells (NSCs) in laminin-chitosan-poly-lactic-co-glycolic acid (laminin-chitosan-PLGA) nerve conduits in rats. A laminin-chitosan-PLGA conduit was used in a rat recurrent laryngeal nerve transection model. check details The rat recurrent laryngeal nerve was dissected to generate a 5  mm defect. Then, a laminin-chitosan-PLGA nerve conduit with or without Schwann cells and NSCs in the lumen was transplanted into the defect. A total of 96 female rats were randomised into six groups co-culture of NSCs and Schwann cells in the nerve conduit group (CO), Schwann cells only in the nerve conduit group (SC), neural stem cells only in the nerve conduit group (NSC-only), nerve conduit group (null), autologous nerve graft group (autograft) and sham operation group (sham). Regenerated nerves were evaluated by histological and functional assessment at 8 and 12 weeks after surgery. The diameter and area of the regenerated myelin sheath, as well as the secretion of brain-derived neurotrophic factor and glial cell-derived neurotrophic factor in laryngeal muscle or regenerated nerve tissue in the CO group, were significantly better than they were in the SC, NSC-only and null groups (all P values   less then   0.05). Immunofluorescence showed that the CO group had significantly more neurofilament-200 immunoreactive and S-100 immunoreactive fibres than the SC, NSC-only and null groups (all P values   less then   0.05). The performance of the CO groups and autograft groups was found to be similar by laryngoscopy. Arytenoid cartilage motion recovery in these two groups was significantly better than it was in the other groups (all P values   less then   0.05). Our results indicated that co-culture of Schwann cells and NSCs in laminin-chitosan-PLGA conduits might promote injured nerve regeneration. This method might be a promising alternative for defective nerve repair.The use of 3D scaffolds based on mesoporous bioactive glasses (MBG) enhanced with therapeutic ions, biomolecules and cells is emerging as a strategy to improve bone healing. In this paper, the osteogenic capability of ZnO-enriched MBG scaffolds loaded or not with osteostatin (OST) and human mesenchymal stem cells (MSC) was evaluated after implantation in New Zealand rabbits. Cylindrical meso-macroporous scaffolds with composition (mol %) 82.2SiO2-10.3CaO-3.3P2O5-4.2ZnO (4ZN) were obtained by rapid prototyping and then, coated with gelatin for easy handling and potentiating the release of inorganic ions and OST. Bone defects (7.5 mm diameter, 12 mm depth) were drilled in the distal femoral epiphysis and filled with 4ZN, 4ZN + MSC, 4ZN + OST or 4ZN + MSC + OST materials to evaluate and compare their osteogenic features. Rabbits were sacrificed at 3 months extracting the distal third of bone specimens for necropsy, histological, and microtomography (µCT) evaluations. Systems investigated exhibited bone regeneration capability. Thus, trabecular bone volume density (BV/TV) values obtained from µCT showed that the good bone healing capability of 4ZN was significantly improved by the scaffolds coated with OST and MSC. Our findings in vivo suggest the interest of these MBG complete systems to improve bone repair in the clinical practice.

C3 glomerulopathy (C3G) is characterized by heterogeneous clinical presentation, outcome, and predominant C3 accumulation in glomeruli without significant IgG. There is scarce outcome data regarding childhood C3G. We describe clinical and pathological features, treatment and outcomes, and risk factors for progression to chronic kidney disease stage 5 (CKD5) in the largest pediatric series with biopsy-proven C3G.

Sixty pediatric patients with C3G from 21 referral centers in Turkey were included in this retrospective study. Patients were categorized according to CKD stage at last visit as CKD5 or non-CKD5. Demographic data, clinicopathologic findings, treatment, and outcome data were compared and possible risk factors for CKD5 progression determined using Cox proportional hazards model.

Mean age at diagnosis was 10.6 ± 3.0years and follow-up time 48.3 ± 36.3months. Almost half the patients had gross hematuria and hypertension at diagnosis. Nephritic-nephrotic syndrome was the commonest presenting feature (41.6%) and 1/5 of patients presented with nephrotic syndrome. Membranoproliferative glomerulonephritis was the leading injury pattern, while 40 patients had only C3 staining. Patients with DDD had significantly lower baseline serum albumin compared with C3GN. Eighteen patients received eculizumab. Clinical remission was achieved in 68.3%. At last follow-up, 10 patients (16.6%) developed CKD5 they had lower baseline eGFR and albumin and higher frequency of nephrotic syndrome and dialysis requirement than non-CKD5 patients. Lower serum albumin and eGFR at diagnosis were independent predictors for CKD5 development.

Children with C3G who have impaired kidney function and hypoalbuminemia at diagnosis should be carefully monitored for risk of progression to CKD5. Graphical abstract.
