Selected letters of Alessandra Strozzi
No full textThe letters of Alessandra Strozzi provide a vivid and spirited portrayal of life in fifteenth-century Florence. Among the richest autobiographical materials to survive from the Italian Renaissance, the letters reveal a woman who fought stubbornly to preserve her family's property and position in adverse circumstances, and who was an acute observer of Medicean society. Her letters speak of political and social status, of the concept of honor, and of the harshness of life, including the plague and the loss of children. They are also a guide to Alessandra's inner life over a period of twenty-three years, revealing the pain and sorrow, and, more rarely, the joy and triumph, with which she responded to the events unfolding around her.This edition includes translations, in full or in part, of 35 of the 73 extant letters. The selections carry forward the story of Alessandra's life and illustrate the range of attitudes, concerns, and activities which were characteristic of their author
Challenging the author: Gavin Douglas's Eneados
No full textGavin Douglas’s Eneados, a translation into the “Scottis” tongue of Virgil’s Aeneid, completed in 1513 and first published in London in 1553, presents, as well as the translation of the additional thirteenth book by Maphaeus Vegius, original prologues and marginal notes to the text, rubrics and articulate conclusive material. The present paper analyses this complex paratext as evidence of Douglas’s almost philological attention to the original and his preoccupation with a faithful reproduction; it is also suggested that the models for his organization of the commentary might be both medieval (i.e., manuscripts such as Petrarch’s Virgilius Ambrosianus) and early modern, as in the case of editions of classical works: the most apt example being Jodocus Badius Ascensius’ edition of the Aeneid, printed in 1501. The Eneados thus stands on the threshold between manuscript and print, and might have indicated new possibilities of use of the printing medium in Scotland, and of the value of the translation of a classical text, had history not intervened with the Scottish defeat at Flodden Fields in 1513, which put a temporary stop both to the circulation of the Eneados and to the development of Scottish printing
Nicetas Nicaenus, De azymis
No full textThe RAP online repertorium offers the first comprehensive catalogue of polemical literature related to the schism between the Roman Catholic and Orthodox Churches from the 9th to the 16th century and can be described as an ideal continuation of the *Clavis Patrum*.
Each entry identifies the work (often unpublished or newly discovered in manuscript catalogs), lists its various titles (since medieval texts often lack stable titles), provides incipit and explicit (with possible variations), and examines the manuscript tradition and foliation (by reviewing catalogs or manuscripts, verifying dates, folios, etc.). It also includes relevant bibliography (critical editions and studies), identifies the author (using prosopographical studies, dictionaries, repertories, sigillography, etc.), and provides essential biographical details. Each work is classified by literary genre (e.g., treatise, dialogue), the corresponding Byzantine term, and the main polemical themes (e.g., Filioque, Azymes, Purgatory), and is assigned a unique RAP identification number.

Impact of COVID-19 Infection, Vaccination, and Serological Response in Immune Thrombocytopenic Purpura Patients: A Single-Center Global Analysis
No full textBoth SARS-CoV-2 infection and vaccination have raised concern in immune-mediated diseases, including immune thrombocytopenic purpura (ITP) considering risk of de novo ITP development and ITP recurrence. Here, we report on data from a single-center retrospective–prospective collection aiming to evaluate platelet (plt) dynamics in patients (pts) with chronic ITP after COVID-19 infection (before and after vaccination) and after the first, second and third vaccine doses. Furthermore, we analyzed the serological response after the first two doses of COVID-19 vaccination. A total of 64 pts currently followed for chronic ITP who experienced COVD-19 infection and/or vaccination with an available plt count before and after such events were included in the analysis. A low incidence of ITP exacerbation following vaccine sessions (6–16%) was observed in comparison with a high frequency of exacerbation and rescue treatment necessity after COVID-19 infection in unvaccinated pts (83%). Moreover, the lower ITP exacerbation rate observed in infected pts previously vaccinated (18%) suggests further protective effects in this population. Finally, a high seroconversion rate was observed, confirming data reported in previously published studies on immune cytopenia and rheumatological diseases, but more evidence is awaited to establish the clinical impact of serological response
Surgery and Prophylaxis with Susoctocog-Alfa in Acquired Hemophilia: Case Series and Literature Review
No full textBackground: Acquired hemophilia A (AHA) is a rare bleeding disease due to autoantibodies directed against clotting factor VIII (FVIII). Treatment of AHA consists of inhibitor eradication with immunosuppressive therapy (IST) and prompt control of bleeding obtained with bypassing agents or recombinant porcine FVIII (rpFVIII). The latter has recently been licensed for management of acute bleeding in AHA. Unlike treatment with bypassing agents, rpFVIII can be monitored to provide a successful hemostatic effect and avoid overtreatment. Correlation between rpFVIII inhibitor titers and efficacy of rpFVIII treatment remains a matter of debate. Methods: We report three cases of AHA in which rpFVIII was successfully used with an unconventional schedule despite the presence of medium–high titers of the rpFVIII. The modified Nijmegen–Bethesda inhibitor assay (NBA) was used to dose porcine FVIII inhibitors. Result: The presence of rpFVIII inhibitors prior to the exposition to susoctocog-alfa, that may suggest a cross-reactivity with human FVIII inhibitors, did not affect hemostasis. Conclusion: In our experience, rpFVIII demonstrates safety and efficacy in the presence of rpFVIII inhibitors and using an unconventional schedule in both the perioperative and outpatient settings. Laboratory measurement of inhibitors against rpFVIII during treatment is described for the first time

ADAMTS13 Autoantibodies and Burden of Care in Immune Thrombotic Thrombocytopenic purpura: New Evidence and Future Implications
No full textThe introduction Caplacizumab in the management of Immune thrombotic thrombocytopenic purpura (iTTP) has raised different questions, considering its cost-efficacy and the optimal immunosuppressive treatment (IST) to associate. A retrospective multicenter collection of 42 first iTTP cases was conducted to identify variables associated with a higher burden of care and necessity of an implemented IST with early Rituximab (RTX) rescue. A significant correlation resulted between ADAMTS13 inhibitors (ADAMTS13inh) at diagnosis with total plasma exchange (PEXtot) and PEX needed to achieve clinical response (PEXtoCR, r = 0.46; r = 0.48), along with age (r = - 0.31; r = -0.35), platelet count (r = -0.30; r = -0.30), LDH (r = 0.44; r = 0.41) and total bilirubin (r = 0.54; r = 0.35). ADAMTS13inh also correlated with number of days of hospitalization (DoH, r = 0.44). A significant difference was observed in terms of median ADAMTS13inh titer at diagnosis in patient treated with RTX rescue and those responding to only steroid treatment. Thus, ADAMTS13inh titer resulted a marker of iTTP burden of care, associated with higher number of PEXtot, PEXtoCR, DoH and higher probability of needing RTX rescue to achieve clinical response and could be a useful tool for management of new iTTP cases and an interesting variable to optimize iTTP cases stratification in future Caplacizumab cost-efficacy analysis
Rescue of a panel of splicing mutations causing hemophilia A by engineered U1snRNAs
No full textBackground. Hemophilia A (HA) is an X-linked recessive
hemorrhagic disorder caused by coagulation factor VIII
(FVIII) deficiency. Among all HA-causing mutations,
those affecting splicing are relatively frequent,
particularly in severe forms. These mutations, often
leading to exon skipping, can be potentially rescued by
RNA therapeutics based on variants of the key U1snRNA
spliceosomal component, as already shown in several
human disease models.
The aim of this project is to dissect the molecular
mechanisms of eight F8 splicing variants identified
in HA patients and located at the 5' splice sites (5'ss) of
exon 6 (c.787+2T>C; c.787+3A>G; c.787+3A>T; c.787+5G>A;
c.787+6T>C) and exon 11 (c.1752+5G>T; c.1752+5G>C;
c.1752+5G>A) and to test engineering U1snRNAs to
restore the correct pre-mRNA processing.
Methods. Molecular cloning of splicing competent
vectors containing the F8 exon 6 or exon 11 with the
respective surrounding introns, either wild-type or
harboring the eight F8 variants (c.787+2T>C; c.787+3A>G;
c.787+3A>T; c.787+5G>A; c.787+6T>C; c.1752+5G>T;
c.1752+5G>C; c.1752+5G>A). Creation of recombinant
vectors expressing engineered U1snRNAs designed
to bind to the mutated 5'ss (compensatory U1snRNA)
or to less-conserved downstream intronic sequences
(Exon Specific U1snRNA, ExSpeU1snRNA). Transient
transfection of expression vectors on various human
cell lines and RT-PCR with plasmid specific primers to
evaluate the splicing patterns and their modulation by
U1snRNA variants.
Results. Firstly, a Bioinformatic analysis with
SpliceRover showed that F8 exon 6 and exon 11 are welldefined
exons and that the mutations do not activate
cryptic 5'splice sites but rather weaken the canonical
5'ss. In vitro splicing pattern analysis revealed that these
mutations lead to exon 6 or exon 11 skipping with low
levels (5-30% based on mutation position within the
5'ss) of correctly spliced transcripts. The reduced levels
of correctly spliced transcripts are in accordance with
the pathological phenotype and observed FVIII antigen
levels, whenever available. We also showed that basal
levels of correctly spliced transcripts are cell-specific,
thus indicating that splicing of these exons is regulated
in a cell-dependent manner. Notably, co-transfection of
U1snRNA variants significantly improves F8 exon 6 and
exon 11 definition and thus inclusion up to 95%.
Conclusions. We provided experimental evidence that the
analysed mutations alter F8 splicing by impairing proper
exon definition. Trace levels of correctly spliced transcripts
are regulated in a cell-dependent manner. Importantly,
exon definition can be efficiently restored by engineered
U1snRNA variants, with one ExSpeU1snRNA able to rescue
different splicing mutations located in the same 5'ss.
