    Background: Since direct-acting antivirals (DAAs) have been approved for the treatment of hepatitis C virus (HCV) infection, a small series of patients with new-onset neuropsychiatric alterations have been referred to us. We therefore set out to study neuropsychiatric function in relation to DAAs prospectively. Methods: Ten patients with cirrhosis and 12 post-liver transplant (post-LT) patients were enrolled. All underwent wake electroencephalography (EEG) and a neuropsychological evaluation (paper and pencil battery, simple/choice reaction times, working memory task) at baseline, at the end of treatment with DAAs and after 6 months. At the same time points, full blood count, liver/kidney function tests, quantitative HCV RNA, ammonia and immunosuppressant drug levels were obtained, as appropriate. Results: Patients with cirrhosis were significantly older than post-LT patients (65\ub112 vs 55\ub17 years; P<0.05). Neuropsychological performance and wake EEG were comparable in the two groups at baseline. At the end of a course of treatment with DAAs, a significant slowing in choice reaction times and in the EEG (increased relative delta power) was observed in patients with cirrhosis, which resolved after 6 months. In contrast, no significant changes over time were observed in the neuropsychiatric performance of post-LT patients. No significant associations were observed between neuropsychiatric performance and stand-alone/combined laboratory variables. Conclusion: Some degree of neuropsychiatric impairment was observed in relation to treatment with DAAs in patients with cirrhosis, but not in post-LT patients, suggesting that the former may be sensitive to mild DAA neurotoxicity

    FIP200 Claw Domain Binding to p62 Promotes Autophagosome Formation at Ubiquitin Condensates

    The autophagy cargo receptor p62 facilitates the condensation of misfolded, ubiquitin-positive proteins and their degradation by autophagy, but the molecular mechanism of p62 signaling to the core autophagy machinery is unclear. Here, we show that disordered residues 326–380 of p62 directly interact with the C-terminal region (CTR) of FIP200. Crystal structure determination shows that the FIP200 CTR contains a dimeric globular domain that we designated the “Claw” for its shape. The interaction of p62 with FIP200 is mediated by a positively charged pocket in the Claw, enhanced by p62 phosphorylation, mutually exclusive with the binding of p62 to LC3B, and it promotes degradation of ubiquitinated cargo by autophagy. Furthermore, the recruitment of the FIP200 CTR slows the phase separation of ubiquitinated proteins by p62 in a reconstituted system. Our data provide the molecular basis for a crosstalk between cargo condensation and autophagosome formation

    Financial dependence and growth: The role of input-output linkages

    Get PDF
    We widen the understanding of the finance-growth nexus by accounting for the indirect effect of financial development through input-output (IO) linkages in determining the growth of industries across countries. If financial development is expected to promote disproportionately more the growth of industrial sectors that are more in need of external finance, it also favours more the industries that are linked by IO relations to more financially dependent industries. We explore this new channel in a sample of countries at different development stages over the period 1995–2007. Our results highlight that financial development, besides easing the growth of industries highly dependent on external finance, also fosters the growth of industries strongly linked to highly financially dependent upstream industries. Moreover, the indirect effect - propagated through IO linkages - of finance has a higher and non-negligible role compared to the direct effect and its omission leads to a biased and underestimated perception of the role of finance for industries’ growth

The aim of our study is to analyse risk factors for p-EB and its impact on mortality. Methods International two-centre retrospective study of all hospitalised adults with enterococcal bacteraemia managed with follow-up blood cultures (BCs) during the period 2011–2019. Exclusion criteria were: (1) death within 72 hours from index BCs and (2) polymicrobial bacteraemia. Primary endpoint was p-EB, defined as further isolation of the same species of Enterococcus spp. from BCs after at least 72 hours of appropriate antibiotic therapy. Multivariable logistic regression model was performed to assess risk factors for p-EB. The impact of p-EB on 30-day mortality was assessed by Kaplan-Meier survival curve and Cox regression multivariable model. Results During the study period, 244 enterococcal bacteraemia were diagnosed. P-EB were 13.5% (33/244). At multivariable analysis, factors independently associated with p-EB were hematologic malignancy (OR 4.60 [95% CI 1.32–16.00], P = 0.01), infective endocarditis (OR 7.99 [95% CI 2.20–28.9], P = 0.002), and use of daptomycin as initial treatment (OR 4.50 [95% CI 1.29–15.61], P = 0.018). Mortality rate was higher in the p-EB group (32% vs. 18%). Kaplan-Meier survival curve showed that patients with p-EB were less likely to survive at 30 days from index BCs (log-rank P = 0.002). Using a Cox regression model, independent predictors of 30-day mortality were hematologic malignancy (HR 2.30 [95% CI 1.02–4.11], P = 0.043), p-EB (HR 1.93 [95% CI 0.92–4.04], P = 0.08), and septic shock (HR 5.92 [95% CI 2.17–16.30], P = 0.001). Conclusion P-EB was diagnosed mainly in very fragile patients and in those receiving daptomycin as frontline therapy. P-EB may have an impact on mortality

    Donation after circulatory determination of death (DCD) is a valuable strategy to increase the availability of grafts for liver transplantation (LT). As the average age of populations rises, the donor pool is likely to be affected by a potential increase in DCD donor age in the near future. We conducted a prospective cohort study to evaluate post-transplantation outcomes in recipients of grafts from elderly DCD donors compared with younger DCD donors, and elderly donors after brainstem determination of death (DBD). From August 2020 to May 2022, consecutive recipients of deceased donor liver-only transplants were enrolled in the study. DCD recipients were propensity score matched 1:3 to DBD recipients. One-hundred fifty-seven patients were included, 26 of whom (16.6%) were transplanted with a DCD liver graft. After propensity score matching and stratification, three groups were obtained: 15 recipients of DCD donors &amp; GE;75 years, 11 recipients of DCD donors &lt;75 years, and 28 recipients of DBD donors &amp; GE;75 years. Short-term outcomes, as well as 12 months graft survival rates (93.3%, 100%, and 89.3% respectively), were comparable among the groups. LT involving grafts retrieved from very elderly DCD donors was feasible and safe in an experienced high-volume center, with outcomes comparable to LTs from younger DCD donors and age-matched DBD donors

    Il processo edilizio supportato dal BIM: l'approccio innovance

    Get PDF
    Il terzo volume della collana dedicata a INNOVance, presenta l’interpretazione del concetto di BIM elaborata durante il progetto. Una prima parte del documento illustra le esperienze del capitolo italiano IAI, nate in seno al Dipartimento BEST del Politecnico di Milano – poi confluito nel dipartimento ABC - e che sono state premessa del progetto INNOVance. Vengono poi mostrati i concetti di BIM e gli esiti del progetto, in particolare le procedure e i requisiti per la produzione di librerie BIM Interoperabili che sono state definite da INNOVance, aspetto quest’ultimo che ha caratterizzato profondamente il lavoro. La questione del BIM e delle librerie BIM è oggetto di particolare attenzione da parte degli operatori dell’industria edilizia, anche grazie a diversi programmi di ricerca internazionali, tra i quali spicca l’esperienza della National BIM Library britannica sotto l’egida del NBS. La tecnologia BIM, oggi vista da molti come forza propulsiva per lo sviluppo e l’innovazione del settore edilizio, richiede standard operativi utili a garantire che l’informazione possa essere condivisa e soprattutto che possa essere utilizzata da tutti gli operatori del processo. Lo sviluppo di librerie BIM interoperabili è una premessa necessaria per questo ed è un passo fondamentale per facilitare la diffusione del BIM nell’intero processo. L’interpretazione del BIM da parte di INNOVance parte da tale assunto. Si è perciò dedicata grande attenzione allo sviluppo delle librerie, per definire le quali si sono prima di tutto individuati alcuni modelli di riferimento da utilizzare come casi studio nei quali sperimentare le soluzioni tecnologiche digitali costruite come oggetti BIM. Questi ultimi, codificati secondo gli standard INNOVance, sono stati verificati in termini di interoperabilità, requisito fondamentale per garantire condivisione e usabilità dell’informazione lungo la filiera edilizia. L’esito del lavoro, per qualità e approfondimento nonché per le proposte avanzate, colloca a buon diritto INNOVance all’avanguardia in ambito internazionale INNOVance ha inoltre tracciato i requisiti, in termini di standard e norme, che hanno portato allo sviluppo della normativa italiana sul BIM attualmente in fase di gestazione e di cui si anticipano alcuni contenuti nel presente testo

    Urban Water Tariffs in Spain: What Needs to Be Done?

    Get PDF
    Recently, in the context of the Integrated Water Resources Management, demand policies are playing a more important role as opposed to traditional supply policies based on the construction of large hydraulic infrastructures. In this new context, water tariffs have become an important tool in achieving economic efficiency, environmental sustainability, and social equity. This paper reviews the situation of urban water tariffs in Spain, a country subject to high water stress. It analyzes the capacity of urban water tariffs to recover service costs and to promote efficiency, sustainability, affordability, and equity. Although it has made significant progress in recent years, the Spanish urban water tariff system still faces many challenges. Many of these challenges would be better addressed by a national independent regulatory body.The authors also gratefully acknowledge the financial support from the following Spanish institutions: the Consejería de Economía, Innovación, Ciencia y Empleo from the Government of Andalusia (P11-SEJ-7039), the Spanish Ministry of Economics and Competitiveness of Spain (Project ECO2012‐32189), and the CEI BioTIC program from Universidad de Granada (mP_CP_3).

    : Background and objective: Fibrinogen and albumin are two proteins widely used, singularly and in combination, in cancer patients as biomarkers of nutritional status, inflammation and disease prognosis. The aim of our study was to investigate the preoperative fibrinogen-to-albumin ratio (FAR) as a preoperative predictor of malignancy as well as advanced grade in patients with bladder cancer. Materials and Methods: A retrospective analysis of patients who underwent TURBT at our institution between 2017 and 2021 was conducted. FAR was obtained from preoperative venous blood samples performed within 30 days from scheduled surgery and was analyzed in relation to histopathological reports, as was the presence of malignancy. Statistical analysis was performed using a Kruskal−Wallis Test, and univariate and multivariate logistic regression analysis, assuming p < 0.05 to be statistically significant. Results: A total of 510 patients were included in the study (81% male, 19% female), with a mean age of 71.66 ± 11.64 years. The mean FAR was significantly higher in patients with low-grade and high-grade bladder cancer, with values of 80.71 ± 23.15 and 84.93 ± 29.96, respectively, compared to patients without cancer (75.50 ± 24.81) (p = 0.006). Univariate regression analysis reported FAR to be irrelevant when considered as a continuous variable (OR = 1.013, 95% CI = 1.004−1.022; p = 0.004), while when considered as a categorical variable, utilizing a cut-off set at 76, OR was 2.062 (95% CI = 1.378−3.084; p < 0.0001). Nevertheless, the data were not confirmed in the multivariate analysis. Conclusions: Elevated preoperative FAR is a potential predictor of malignancy as well as advanced grade in patients with bladder cancer. Further data are required to suggest a promising role of the fibrinogen-to-albumin ratio as a diagnostic biomarker for bladder tumors
