A Dominican Gradual of Saints, circa 1500

LATE IN 1989 the Syracuse University Library received a manuscript volume of ecclesiastical chant (Syracuse University Library, Ms. I I) as part of a bequest from Barbara Weiss of Detroit, Michigan. No information about its history accompanied it. The purpose of this paper is to provide an introduction to this important addition to the rare books and manuscript collections of Syracuse University\u27s George Arents Research Library. During the Middle Ages and Renaissance there were many kinds of chant books, such as Antiphonals and Graduals (which contain the chants used throughout the year in celebrating, respectively, the Divine Office and the Mass). This particular manuscript at Syracuse University contains the equivalent of what came to be known during the sixteenth century as a Gradual of Saints, which provides Mass chants used in celebrating saints\u27 feasts and other holidays of the church calendar. This form of choir book came into use after the advent of printing, so that finding a manuscript version is somewhat unusual. However, the most unusual aspect of this manuscript, as I will show, is the age of the chant tradition it preserves: a Dominican tradition, which predates that religious order\u27s reform, finalized in 1256 under the supervision of Humbert of Romans

A common ontology for multi-dimensional shapes

In recent years, digital shapes have become more and more widespread and have been made available in a plethora of online repositories. A systematic and formal approach for capturing and representing shape-related information is needed to facilitate its reuse and enable the demonstration of useful cross-domain usage scenarios. In this paper we present an ontology for digital shapes, called the Common Shape Ontology (CSO). We discuss the rationale, the requirements and the scope of this ontology, we present in detail its structure and describe the most relevant choices related to its development. Finally, we show how the CSO conceptualization is used in domain-specific application scenarios

Rodents of Senegal and their role as intermediate hosts of Hydatigera spp. (Cestoda: Taeniidae)

Hydatigera (Cestoda: Taeniidae) is a recently resurrected genus including species seldom investigated in sub-Saharan Africa. We surveyed wild small mammal populations in the areas of Richard Toll and Lake Guiers, Senegal, with the objective to evaluate their potential role as intermediate hosts of larval taeniid stages (i.e. metacestodes). Based on genetic sequences of a segment of the mitochondrial DNA gene cytochrome c oxidase subunit 1 (COI), we identified Hydatigera parva metacestodes in 19 out of 172 (11.0%) Hubert's multimammate mice (Mastomys huberti) and one out of six (16.7%) gerbils (Taterillus sp.) and Hydatigera taeniaeformis sensu stricto metacestodes in one out of 215 (0.5%) Nile rats (Arvicanthis niloticus). This study reports epidemiological and molecular information on H. parva and H. taeniaeformis in West African rodents, further supporting the phylogeographic hypothesis on the African origin of H. parva. Our findings may indicate significant trophic interactions contributing to the local transmission of Hydatigera spp. and other parasites with similar life-cycle mechanisms. We therefore propose that further field investigations of rodent population dynamics and rodent-borne infectious organisms are necessary to improve our understanding of host–parasite associations driving the transmission risks of rodent parasites in West Africa

Benchmarks in Liver Resection for Intrahepatic Cholangiocarcinoma

Introduction: Benchmarking in surgery has been proposed as a means to compare results across institutions to establish best practices. We sought to define benchmark values for hepatectomy for intrahepatic cholangiocarcinoma (ICC) across an international population. Methods: Patients who underwent liver resection for ICC between 1990 and 2020 were identified from an international database, including 14 Eastern and Western institutions. Patients operated on at high-volume centers who had no preoperative jaundice, ASA class &lt;3, body mass index &lt;35 km/m2, without need for bile duct or vascular resection were chosen as the benchmark group. Results: Among 1193 patients who underwent curative-intent hepatectomy for ICC, 600 (50.3%) were included in the benchmark group. Among benchmark patients, median age was 58.0 years (interquartile range [IQR] 49.0–67.0), only 28 (4.7%) patients received neoadjuvant therapy, and most patients had a minor resection (n = 499, 83.2%). Benchmark values included ≥3 lymph nodes retrieved when lymphadenectomy was performed, blood loss ≤600 mL, perioperative blood transfusion rate ≤42.9%, and operative time ≤339 min. The postoperative benchmark values included TOO achievement ≥59.3%, positive resection margin ≤27.5%, 30-day readmission ≤3.6%, Clavien-Dindo III or more complications ≤14.3%, and 90-day mortality ≤4.8%, as well as hospital stay ≤14 days. Conclusions: Benchmark cutoffs targeting short-term perioperative outcomes can help to facilitate comparisons across hospitals performing liver resection for ICC, assess inter-institutional variation, and identify the highest-performing centers to improve surgical and oncologic outcomes.</p

Comparison between tofacitinib and ustekinumab as a third-line therapy in refractory ulcerative colitis: multicenter international study

Background: Ustekinumab and tofacitinib have recently been approved for the management of moderate to severe ulcerative colitis (UC). However, there is no evidence on how they should be positioned in the therapeutic algorithm. The aim of this study was to compare tofacitinib and ustekinumab as third-line therapies in UC patients in whom anti-TNF and vedolizumab had failed. Methods: This was a multicenter retrospective observational study. The primary outcome was disease progression, defined as the need for steroids, therapy escalation, UC-related hospitalization and/or surgery. Secondary outcomes were clinical remission, normalization of C-reactive protein, endoscopic remission, treatment withdrawal, and adverse events. Results: One-hundred seventeen UC patients were included in the study and followed for a median time of 11.6 months (q₁–q₃, 5.5-18.7). Overall, 65% of patients were treated with tofacitinib and 35% with ustekinumab. In the entire study cohort, 63 patients (54%) had disease progression during the follow-up period. Treatment with ustekinumab predicted increased risk of disease progression compared to treatment with tofacitinib in Cox regression analysis (HR: 1.93 [95% CI: 1.06-3.50] p = 0.030). Twenty-eight (68%) patients in the ustekinumab group and 35 (46%) in the tofacitinib group had disease progression over the follow-up period (log-rank test, p < 0.054). No significant differences were observed for the secondary outcomes. Six and 22 adverse events occurred in the ustekinumab and tofacitinib groups, respectively (15% vs. 31%, p = 0.11). Conclusions: Tofacitinib was more efficacious in reducing disease progression than ustekinumab in this cohort of refractory UC patients. However, prospective head-to-head clinical trials are needed as to confirm these data.ACKNOWLEDGMENTS: The authors received no financial support for the research, authorship, and/or publication of this article.

Development and Validation of a Predictive Risk Score for Blood Transfusion in Patients Undergoing Curative-Intent Surgery for Intrahepatic Cholangiocarcinoma

Background and Objectives: Among patients undergoing liver resection for intrahepatic cholangiocarcinoma (ICC), perioperative bleeding requiring blood transfusion is a common complication, yet preoperative identification of patients at risk for transfusion remains challenging. The objective of this study was to develop a preoperative risk score for blood transfusion requirement during surgery for ICC. Methods: Patients undergoing curative-intent liver surgery for ICC (1990–2020) were identified from a multi-institutional database. A predictive model was developed and validated. An easy-to-use risk calculator was made available online. Results: Among 1420 patients, 300 (21.1%) received an intraoperative transfusion. Independent predictors of transfusion included severe preoperative anemia (OR = 1.65, 95% CI 1.10–2.47), T2 category or higher (OR = 2.00, 95% CI 1.36–3.02), positive lymph nodes (OR = 1.75, 95% CI 1.32–2.32) and major resection (OR = 2.56, 95%CI 1.85–3.58). Receipt of blood transfusion significantly correlated with worse outcomes. The model showed good discriminative ability in both training (AUC = 0.68, 95% CI 0.66–0.72) and bootstrapping validation (C-index = 0.67, 95% CI 0.65–0.70) cohorts. An online risk calculator of blood transfusion requirement was developed (https://catalano-giovanni.shinyapps.io/TransfusionRisk). Conclusions: Intraoperative blood transfusion was significantly associated with poor postoperative outcomes among patients undergoing surgery for ICC. The identification of patients at high risk of transfusion could improve perioperative patient care and blood resources allocation.</p
