La contribution de la "squadra belga" au Concile Vatican II

En este artículo, basado en una exhaustiva investigación archivística, queremos presentar el papel de la llamada «squadra belga» en el Concilio Vaticano ii. Nuestra contribución muestra, claramente, que la Squadra Belga consistía en un grupo bastante pequeño de obispos y teólogos que se conocían muy bien entre ellos ya que habían estudiado juntos en Roma y residían en el Colegio Belga. Además, los obispos belgas nombraban a los profesores de teología de la Universidad Católica de Lovaina e intercambiaban impresiones con los teólogos de manera regular. En definitiva, existía una confianza mutua. Varios de estos teólogos eran apreciados internacionalmente por sus investigaciones y su compromiso con el ecumenismo, las ciencias bíblicas, patrísticas y afines. A diferencia de algunos teólogos franceses y alemanes, los profesores de Lovaina nunca habían sido objeto de condenas. Los belgas participaron activamente y tuvieron un papel importante en la elaboración de lo que llegarían a ser varios documentos conciliares: Lumen Gentium, Dei Verbum, Unitatis Redintegratio, Dignitatis Humanae y Gaudium et Spes, por mencionar solo los documentos en que su contribución es más visible

The importance of sizing in sutureless valves.

Avoiding oversizing in sutureless valves leads to lower transvalvular gradients and less permanent pacemaker implants postoperatively.

peer reviewed[en] OBJECTIVES: The aim of this study was to evaluate the impact of changing the sizing strategy in aortic valve replacement using the Perceval sutureless prosthesis on haemodynamic outcomes and postoperative pacemaker implantation. METHODS: Retrospective analysis of patients implanted with the Perceval valve between 2007 and 2019 was performed by comparing patients implanted before the modification of sizing strategy (OLD group) and after (NEW group). The outcome parameters evaluated were the implanted prosthesis size, haemodynamical profile and postoperative pacemaker implantation. RESULTS: The entire patient cohort (784 patients) consisted of 52% female patients, with a mean age of 78.53 [standard deviation (SD): 5.8] years and a mean EuroSCORE II of 6.3 (range 0.7-76). In 55.5% of cases, surgery was combined. The NEW cohort had more male patients (54.6% vs 43.4%) (P = 0.002). Mean implanted valve size, corrected for body surface area, was significantly lower in the NEW cohort (13.1, SD: 1.4 vs 13.5, SD: 1.4 mm/m2, P < 0.001). The 30-day mortality was 3.4%. Peak and mean transvalvular gradients at discharge were significantly lower in the NEW versus OLD groups: 24.4 mmHg (SD: 9.2) versus 28.4 mmHg (SD: 10.3) (P < 0.001) and 13.6 mmHg (SD: 5.3) versus 15.5 mmHg (SD: 6.0) (P < 0.001). The mean effective opening area and the indexed effective opening area, respectively, increased from 1.5 cm2 (SD: 0.5) and 0.85 cm2/m2 (SD: 0.27) in the OLD group to 1.7 cm2 (SD: 0.5) and 0.93 cm2/m2 (SD: 0.30) in the NEW group (P < 0.001). No difference was found in paravalvular leakage ≥1/4. Centrovalvular leakage ≥1/4 significantly decreased from 18% to 7.9% (P < 0.001). With the new sizing, the new postoperative pacemaker implantation rate decreased significantly from 11% to 6.1% (P = 0.016). CONCLUSIONS: Correct sizing of sutureless aortic valves is crucial to obtain the best possible haemodynamics and avoid complications

<p>Insect bite hypersensitivity (IBH), which is a cutaneous allergic reaction to antigens from Culicoides spp., is the most prevalent skin disorder in horses. Misdiagnosis is possible, as IBH is usually diagnosed based on clinical signs. Our study is the first to employ IgE levels against several recombinant Culicoides spp. allergens as an objective, independent, and quantitative phenotype to improve the power to detect genetic variants that underlie IBH. Genotypes of 200 Shetland ponies, 127 Icelandic horses, and 223 Belgian Warmblood horses were analyzed while using a mixed model approach. No single-nucleotide polymorphism (SNP) passed the Bonferroni corrected significance threshold, but several regions were identified within and across breeds, which confirmed previously identified regions of interest and, in addition, identifying new regions of interest. Allergen-specific IgE levels are a continuous and objective phenotype that allow for more powerful analyses when compared to a case-control set-up, as more significant associations were obtained. However, the use of a higher density array seems necessary to fully employ the use of IgE levels as a phenotype. While these results still require validation in a large independent dataset, the use of allergen-specific IgE levels showed value as an objective and continuous phenotype that can deepen our understanding of the biology underlying IBH.</p
