    Can we say that the 18th century philosophe Denis Diderot and his theses of theatrical aesthetics are still relevant and viable on the modern theatre stage? The article elaborates on our contemporaneity to try to give an answer to this question, creating questionnaires-interviews with four professional actors with questions related to the key themes of Diderot's theatrical and artistic aesthetics, encountering the incredible actuality of the Diderotian vision. The idea of the actor's profession is, in its true essence, an aesthetic idea, thus stimulating a philosophical reflection based on all the great concepts of this discipline, highlighted by the theoretical and practical thought of Diderot and now investigated by the theatrical practice of contemporary actors: body, gestures, genius, interpretation, communication, expression. The sentiment of the Diderotian comédien on stage overcomes the distinction between a "warm", involved and passionate acting and a "cold", rational and controlled one, and declines its sensibility in a supra-individual meaning, in a concrete presentation of a model with a universal value but possible for the body of the actor on stage, therefore shared by spectators who observe the events happening on stage. In the same way, the modern actor trains on stage, organically and honestly, towards "becoming" in every moment and towards being legible, credible, creative, bringing to the stage actions full of questions that explore the possibilities of being human. In other words, becoming - as one of the actors interviewed in the questionnaire states in a very Diderotian way - «body of all bodies. A body that knows and can tell something universal and that makes vibrate inside the viewer the internal velvet that moves the soul. Even looking at something unrecognizable directly or consciously, I will feel narrated as a human being».Can we say that the 18th century philosophe Denis Diderot and his theses of theatrical aesthetics are still relevant and viable on the modern theatre stage?

    This interview with Carmelo Rifici, Drama School Director of the Piccolo Teatro di Milano and award-winning theatrical director, discuss on the relationship between some thesis of theatrical aesthetics of the 18th century philosophe Denis Diderot, enclosed in their most complete way in the work Paradox of the actor, and the contemporary reflection on theatre, but also the practice of acting itself. How much does Diderot's thought still question and stimulate the debate on the experience of theatre in its various themes? Without neglecting the contents of this thought, on which 20th century theatre has been questioned a lot and which also emerge in all their facets and possible developments in the interview, during the interesting conversation with Rifici it appears that the true modernity of diderotian reflection and its still generating force today, lies in its asystematic character, in the search for paradox, for perennial question, as a fundamental element for preserving the theatre and its "mystery". It is necessary asking others and themselves questions rather than defining solutions, to restore the theatrical experience, which is the experience of an event, in all its complexity, in diderotian theatrical theory as well as in modern acting practice.This interview with Carmelo Rifici, Drama School Director of the Piccolo Teatro di Milano and award-winning theatrical director, discuss on the relationship between some thesis of theatrical aesthetics of the 18th century philosophe Denis Diderot, enclosed in their most complete way in the work Paradox of the actor, and the contemporary reflection on theatre, but also the practice of acting itself.

    Methods HIV pos women (N = 410) were followed since 1995 in a longitudinal study. Each one undergo periodic (6–12 months) colposcopy, PAP smear, biopsy if needed, and cervical sampling for HPV testing. HIV related parameters (CD4, HIV-RNA, ART) are recorded and related to cervical disease. HPV typing is performed by reverse hybridisation assays, viral load by in-house real time PCR and viral expression by E6/E7 mRNA detection. The Mann-Whitney rank sum test for non-parametric data and the association between discrete variables by Chi-square test of Fisher exact test were applied

    Virological pattern of hepatitis B infection in an HIV-positive man with fatal fulminant hepatitis B: a case report

    <p>Abstract</p> <p>Introduction</p> <p>There seem to be no published data concerning the clinical impact of populations of hepatitis B virus (HBV) in the hepatic and extrahepatic compartments of HIV-infected people with severe acute hepatitis.</p> <p>Case presentation</p> <p>A 26-year-old Caucasian man presenting to our hospital with clinical symptoms suggesting acute hepatitis was found to have an acute hepatitis B profile upon admission. He developed fatal fulminant hepatitis and was found to be heavily immunocompromised due to HIV-1 infection. He had a high plasma HBV and HIV load, and analysis of the partial pre-S1/pre-S2 domain showed the presence of mixed infection with D and F genotypes. Analysis of the point mutations within this region revealed the presence of HBV strains with amino acid substitutions at the immunodominant epitopes involved in B or T cell recognition. A homogeneous population of a pre-core mutant strain harbouring the A1896G and A1899G affecting HBeAg expression was invariably found in the liver tissue, plasma and peripheral blood mononuclear cells despite active HBeAg secretion; it was the dominant strain in the liver only, and was characterised by the presence of two point mutations in the direct repeat 1 domain involved in HBV replication activity. Taken together, these mutations are indicative of a highly replicative virus capable of evading immune responses.</p> <p>Conclusion</p> <p>This case report provides clinical evidence of a possible association between the rapid spread of highly replicative escape mutants and the development of fulminant hepatitis in a heavily immunocompromised patient. Virological surveillance of severe acute hepatitis B may be important in establishing an early treatment strategy involving antiviral drugs capable of preventing liver failure, especially in individuals for whom liver transplantation is not accepted as a standard indication.</p

    Sustained virological response after ten days of triple anti-hepatitis C virus (HCV) therapy with telaprevir plus pegylated interferon and ribavirin in an HIV/HCV co-infected cirrhotic woman

    The introduction of first-generation protease inhibitors for the treatment of chronic hepatitis C in subjects infected with hepatitis C virus (HCV) genotype 1 has significantly improved the sustained virological response (SVR) rate. As liver cirrhosis reduces the probability of achieving SVR, current guidelines discourage response-guided therapy in cirrhotic patients. We report the first case of a cirrhotic woman with chronic HCV and HIV co-infection achieving virological response after an ultra-short course of therapy. A 40-year-old HIV/HCV co-infected woman with compensated liver cirrhosis was treated with anti-HCV triple therapy containing telaprevir plus pegylated interferon and ribavirin. Baseline plasma HCV RNA was 3.6 log IU/ml and transaminases were within the normal range. She harboured IL28B rs12979860 C/C alleles. Ten days after starting therapy, the patient stopped treatment because of mild anorexia and nausea. Virological response was detected at treatment discontinuation and was maintained up to 24 weeks. This case describes an unexpected SVR after a 10-day course of antiviral therapy in a cirrhotic HIV/HCV co-infected woman presenting positive predictive factors for a response (low viral load, IL28B genotype). Nonetheless, there is no evidence to suggest a shorter duration of treatment in this subset of patients

    Survival Outcomes and Effect of Early vs. Deferred cART Among HIV-Infected Patients Diagnosed at the Time of an AIDS-Defining Event: A Cohort Analysis

    Objectives: We analyzed clinical progression among persons diagnosed with HIV at the time of an AIDS-defining event, and assessed the impact on outcome of timing of combined antiretroviral treatment (cART).Methods: Retrospective, European and Canadian multicohort study.. Patients were diagnosed with HIV from 1997-2004 and had clinical AIDS from 30 days before to 14 days after diagnosis. Clinical progression (new AIDS event, death) was described using Kaplan-Meier analysis stratifying by type of AIDS event. Factors associated with progression were identified with multivariable Cox regression. Progression rates were compared between those starting early (<30 days after AIDS event) or deferred (30-270 days after AIDS event) cART.Results: The median (interquartile range) CD4 count and viral load (VL) at diagnosis of the 584 patients were 42 (16, 119) cells/mu L and 5.2 (4.5, 5.7) log(10) copies/mL. Clinical progression was observed in 165 (28.3%) patients. Older age, a higher VL at diagnosis, and a diagnosis of non-Hodgkin lymphoma (NHL) (vs. other AIDS events) were independently associated with disease progression. Of 366 patients with an opportunistic infection, 178 (48.6%) received early cART. There was no significant difference in clinical progression between those initiating cART early and those deferring treatment (adjusted hazard ratio 1.32 [95% confidence interval 0.87, 2.00], p = 0.20).Conclusions: Older patients and patients with high VL or NHL at diagnosis had a worse outcome. Our data suggest that earlier initiation of cART may be beneficial among HIV-infected patients diagnosed with clinical AIDS in our setting

    BACKGROUND: Chronic hepatitis C is more aggressive during HIV infection. Available data about risk factors of liver fibrosis in HIV/HCV co-infected patients derive from studies based on a single liver biopsy. OBJECTIVES: To evaluate the risk factors of liver fibrosis progression (LFP) and to investigate the role of antiretroviral therapy (ARV) in HIV/HCV patients who underwent paired liver biopsy. PATIENTS AND METHODS: We retrospectively studied 58 patients followed at two Infectious Diseases Departments in Northern Italy during the period 1988-2005. All specimens were double-blinded and centrally examined by two pathologists. LFP was defined when an increase of at least one stage occurred in the second biopsy, according to the Ishak-Knodell classification. RESULTS: In a univariate analysis, serum levels of alanine aminotransferase (ALT) > 150 IU/L at the first biopsy (P = 0.02), and a > 20% decrease in CD4+ cell count between the two biopsies (P = 0.007), were significantly associated with LFP. In multivariate analysis, a > 20% decrease in CD4+ cell count remained independently associated to LFP (Odds Ratio, 3.99; 95% confidence interval, 1.25-12.76; P < 0.02). Analysis of life survival curves confirmed the correlation between CD4+ cell count and LFP. CONCLUSIONS: Our findings highlight that in HIV/HCV coinfected patients, an effective antiretroviral therapy that assures a good immune-virological profile contributes to reducing the risk of LF

    Detection of low-level HCV variants in DAA treated patients: comparison amongst three different NGS data analysis protocols

    Get PDF
    Background: Notwithstanding the efforts of direct-acting antivirals (DAAs) for the treatment of chronically infected hepatitis C virus (HCV) patients, concerns exist regarding the emergence of resistance-associated substitutions (RAS) related to therapy failure. Sanger sequencing is still the reference technique used for the detection of RAS and it detects viral variants present up to 15%, meaning that minority variants are undetectable, using this technique. To date, many studies are focused on the analysis of the impact of HCV low variants using next-generation sequencing (NGS) techniques, but the importance of these minority variants is still debated, and importantly, a common data analysis method is still not defined. Methods: Serum samples from four patients failing DAAs therapy were collected at baseline and failure, and amplification of NS3, NS5A and NS5B genes was performed on each sample. The genes amplified were sequenced using Sanger and NGS Illumina sequencing and the data generated were analyzed with different approaches. Three different NGS data analysis methods, two homemade in silico pipeline and one commercially available certified user-friendly software, were used to detect low-level variants. Results: The NGS approach allowed to infer also very-low level virus variants. Moreover, data processing allowed to generate high accuracy data which results in reduction in the error rates for each single sequence polymorphism. The results improved the detection of low-level viral variants in the HCV quasispecies of the analyzed patients, and in one patient a low-level RAS related to treatment failure was identified. Importantly, the results obtained from only two out of the three data analysis strategies were in complete agreement in terms of both detection and frequency of RAS. Conclusions: These results highlight the need to find a robust NGS data analysis method to standardize NGS results for a better comprehension of the clinical role of low-level HCV variants. Based on the extreme importance of data analysis approaches for wet-data interpretation, a detailed description of the used pipelines and further standardization of the in silico analysis could allow increasing diagnostic laboratory networking to unleash true potentials of NGS
