We identified lack of clarity about treatment cost, treatment complications and likelihood of cure as ongoing patient-level barriers to screening and linkage to care. Provider-level barriers included scepticism about establishing HCV screening as a quality metric given competing clinical priorities, particularly for patients with multiple comorbidities. However, most felt positively about adding HCV as a quality metric to enhance HCV screening and linkage to care. Provider engagement yielded suggestions for process improvements that resulted in increased stakeholder buy-in and real-time enhancements to the HCV screening process intervention. Systematic data collection at baseline and during practice change implementation may facilitate adoption and adaptation to improve HCV screening guideline implementation. Findings identified several key opportunities and lessons to enhance the impact of practice change interventions to improve HCV screening and treatment delivery. © 2020 John Wiley & Sons Ltd.AIM To evaluate the effect of adding the dipeptidyl-peptidase-4 inhibitor vildagliptin to insulin on the glycaemic control of patients with type 2 diabetes undergoing haemodialysis. METHODS Overall, 65 insulin-treated patients with type 2 diabetes undergoing haemodialysis (HbA1c 7.3% ± 1.1%; age 70.5 ± 8.5 years) were randomized (11) either to receive vildagliptin 50 mg/day in addition to insulin (vildagliptin-insulin group) or to pursue their usual insulin regimen (insulin-only group). Continuous glucose monitoring (CGM) was performed for 48 ± 6 hours at baseline and at week 12. The primary study endpoint was change from baseline in mean interstitial glucose using CGM. The secondary endpoints included other CGM variables and glucose control markers. RESULTS After 12 weeks, a greater reduction in mean CGM glucose from baseline was observed in the vildagliptin-insulin group compared with the insulin-only group, although the between-treatment difference was not statistically significant (mean difference [CI 95%] -0.96 mmol/L [-2.09; 0.18] vs. -0.29 mmol/L [-1.29; 0.76], P = 0.32). However, a significant decrease from baseline in HbA1c, glycated albumin and insulin daily doses was observed in the vildagliptin-insulin group versus the insulin-only group (-0.6% [-1.19; -0.1], P less then  0.01), in the vildagliptin-insulin group versus no change in the insulin-only group (-130.6 μmol/L [-271; 10.7] vs. +36.2 μmol/L [-164.4; 236.9], P = 0.04 and - 5.9 IU/day [-1.8; 7.1] vs. +1.1 IU/day [-14.5; 16.6], P = 0.01, respectively). There was no significant difference in the percentage of time spent in hypoglycaemia using CGM, occurrence of severe hypoglycaemia or number of adverse events. CONCLUSION In this study, vildagliptin added to insulin improved glycaemic control with an associated insulin-sparing effect in patients with type 2 diabetes undergoing haemodialysis and was well tolerated. © 2020 John Wiley & Sons Ltd.Ferroelectric oxide memristors are currently in the highlights of a thriving area of research aiming at the development of nonvolatile, adaptive memories for applications in neuromorphic computing. However, to date a precise control of synapse-like functionalities by adjusting the interplay between ferroelectric polarization and resistive switching processes is still an ongoing challenge. Here, it is shown that by means of controlled electron beam radiation, a prototypical ferroelectric film of BaTiO3 can be turned into a memristor with multiple configurable resistance states. Ex situ and in situ analyses of current/voltage characteristics upon electron beam exposure confirm the quasi-continuous variation of BaTiO3 resistance up to two orders of magnitude under the typical experimental conditions employed in electron beam patterning and characterization techniques. These results demonstrate an unprecedented effective route to locally and scalably engineering multilevel ferroelectric memristors via application of moderate electron beam radiation. © 2020 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.The Fanconi anemia (FA) pathway is mainly involved in DNA interstrand crosslinks (ICLs) repair in the genome. Several FA genes, including FANCD1/BRCA2, FANCM, and FANCU/XRCC2, have been identified as causative genes for premature ovary insufficiency (POI). Fanconi anemia group L protein (FANCL) cooperates with FANCT/UBE2T to ubiquitinate the FANCI-D2 dimer, which is a crucial event in the process of ICLs repair. Fancl-knockout mice phenocopy human POI, but the role of FANCL mutations in POI pathogenesis has not been confirmed. In the present work, potentially pathogenic mutations in the FANCL gene were screened in 200 Chinese patients with idiopathic POI and in 200 matched controls. Two novel heterozygous frameshift mutations, c.1048_1051delGTCT (p.Gln350Valfs*18) and c.739dupA (p.Met247Asnfs*4), were identified in the FANCL gene in POI patients but not in controls. Wild-type FANCL protein was predominantly localized in the nuclei, while both mutant FANCL proteins were retained in the cytoplasm. In addition, the FANCL variants exhibited impaired ubiquitin-ligase activity and compromised DNA repair ability after mitomycin C treatment. Furthermore, the FANCL variants were deleterious and might be associated with haploinsufficiency. Our results show that FANCL mutations are potentially causative for POI by disrupting DNA damage repair processes. © 2020 Wiley Periodicals, Inc.BACKGROUND Food bank use has increased significantly in the UK. With the rise in demand, it is imperative that users are receiving food parcels that meet their requirements. The present study aimed to explore whether typical food parcels, supplied by The Trussell Trust and independent food banks, were meeting the daily nutrient and energy requirements of an adult user. METHODS The Trussell Trust (n = 2) and independent food banks (n = 9) were surveyed in Oxfordshire, UK. Data were collected on food bank use, resources, donations and parcel content. The energy and nutrient contents of a representative parcel were compared with the average dietary reference values (DRVs) for an adult. Additional comparisons were made between The Trussell Trust and independent provision. RESULTS Parcels provided energy, carbohydrate, sugar, protein and fibre contents that significantly exceeded the DRVs. In total, 62.2% of energy was provided as carbohydrate and 569% of the DRV was provided by sugars. click here The vitamin D and retinol content of the parcels was significantly lower than the DRVs, meeting 25% and 27% of users' needs respectively; provision of all other micronutrients exceeded the DRVs.
