Triggering Mechanisms of Tsunamis in the Gulf of Cadiz and the Alboran Sea: An Overview

The Gulf of Cadiz and the Alboran Sea are characterized by tectonic activity due to oblique convergence at the boundary between the Eurasian and Nubian plates. This activity has favoured a variety of tsunamigenic sources: basically, seismogenic faults and submarine landslides. The main tsunamigenic faults in the Gulf of Cadiz would comprise the thrust systems of Gorringe Ridge, Marquês de Pombal, São Vicente Canyon, and Horseshoe faults with a high susceptibility; meanwhile in the Alboran Sea would be the thrust system of the northern Alboran Ridge with high susceptibility, and the thrust systems of north Xauen and Adra margin, the transpressive segment of Al Idrissi fault, and the Yusuf-Habibas and Averroes faults, with moderate to high susceptibility. The areas with the greatest potential to generate tsunamigenic submarine landslides are in the Gulf of Cadiz, the São Vicente Canyon, Hirondelle Seamount, and Gorringe Ridge; and in the Alboran Sea are the southern and northern flanks of Alboran Ridge. Both sources are likely to generate destructive tsunamis in the Gulf of Cadiz, given its history of bigger earthquakes (>7 Mw) and larger landslides. To fully assess tsunamigenic sources, further work needs to be performed. In the case of seismogenic faults, research focuses on geometry, offsets, timing, paleoearthquakes, and recurrence, and in landslides on early post-failure evolution, age, events, and recurrence. In situ measurements, paleotsunami records, and long-term monitoring, in addition to major modelling developments, will be also necessary.Versión del edito

Outcomes from elective colorectal cancer surgery during the SARS-CoV-2 pandemic

This study aimed to describe the change in surgical practice and the impact of SARS-CoV-2 on mortality after surgical resection of colorectal cancer during the initial phases of the SARS-CoV-2 pandemic

Mortality and pulmonary complications in patients undergoing surgery with perioperative SARS-CoV-2 infection: an international cohort study

Background: The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on postoperative recovery needs to be understood to inform clinical decision making during and after the COVID-19 pandemic. This study reports 30-day mortality and pulmonary complication rates in patients with perioperative SARS-CoV-2 infection. Methods: This international, multicentre, cohort study at 235 hospitals in 24 countries included all patients undergoing surgery who had SARS-CoV-2 infection confirmed within 7 days before or 30 days after surgery. The primary outcome measure was 30-day postoperative mortality and was assessed in all enrolled patients. The main secondary outcome measure was pulmonary complications, defined as pneumonia, acute respiratory distress syndrome, or unexpected postoperative ventilation. Findings: This analysis includes 1128 patients who had surgery between Jan 1 and March 31, 2020, of whom 835 (74·0%) had emergency surgery and 280 (24·8%) had elective surgery. SARS-CoV-2 infection was confirmed preoperatively in 294 (26·1%) patients. 30-day mortality was 23·8% (268 of 1128). Pulmonary complications occurred in 577 (51·2%) of 1128 patients; 30-day mortality in these patients was 38·0% (219 of 577), accounting for 81·7% (219 of 268) of all deaths. In adjusted analyses, 30-day mortality was associated with male sex (odds ratio 1·75 [95% CI 1·28–2·40], p\textless0·0001), age 70 years or older versus younger than 70 years (2·30 [1·65–3·22], p\textless0·0001), American Society of Anesthesiologists grades 3–5 versus grades 1–2 (2·35 [1·57–3·53], p\textless0·0001), malignant versus benign or obstetric diagnosis (1·55 [1·01–2·39], p=0·046), emergency versus elective surgery (1·67 [1·06–2·63], p=0·026), and major versus minor surgery (1·52 [1·01–2·31], p=0·047). Interpretation: Postoperative pulmonary complications occur in half of patients with perioperative SARS-CoV-2 infection and are associated with high mortality. Thresholds for surgery during the COVID-19 pandemic should be higher than during normal practice, particularly in men aged 70 years and older. Consideration should be given for postponing non-urgent procedures and promoting non-operative treatment to delay or avoid the need for surgery.

Dimensiones de la composición escrita en EGB y EEMM : madurez sintáctica y narrativa

Analizar la estructura factorial de la expresión escrita en las edades escolares, a la búsqueda de una dimensión de complejidad sintáctica que, caso de variar sistemáticamente con la edad, permitiera la definición de una madurez sintáctica y la construcción de un índice para medirla. Clarificar el papel de los conocimientos académico-formales de la lengua en la redacción, y las relaciones de los juicios globales de calidad con otras variables de las redacciones. 405 alumnos de ambos sexos de tercero, quinto y séptimo de EGB y de primero y tercero de BUP, de seis colegios de La Rioja. Se pidió a los alumnos de la muestra que realizasen dos redacciones sobre dos historietas sin texto, por lo que la investigación se puede considerar replicada. Además de las variables de los sujetos, que incluyen dos de conocimientos de Lengua, de cada redacción se han tomado 44 variables relativas, una a la calidad global, tres a la productividad, ocho a las partes de la oración, tres a aspectos semánticos, catorce a la estructura oracional, siete a la estructura interna de la proposición y ocho a errores. El análisis de los resultados de las variables por cursos nos muestra que 32 de las variables de la redacción varían lineal y significativamente con la edad. El aspecto que más fuertemente varía es la velocidad de redacción. Varían también la variedad de vocabulario empleado, la abstracción de los términos y la utilización de las partes de la oración. Se produce una disminución de los errores, especialmente los de puntuación, ortográficos y los pronombres y nexos. En cuanto a los componentes sintácticos, lo más destacado es la disminución del número de oraciones y el aumento de su tamaño, así como la disminución de la coordinación y el aumento de la subordinación en cantidad, variedad y profundidad. Es más correcto hablar de madurez narrativa que de madurez sintáctica. Algunos aspectos limitados de ésta podrían ser componentes de aquélla, como la mayor longitud de la frase y el incremento de la subordinación y aún éstos podrían ser más bien consecuencia necesaria de la mayor complejidad de las representaciones del mundo con la edad; en tal caso no serían reflejo de un mayor dominio sintáctico.Ministerio Educación CIDEBiblioteca de Educación del Ministerio de Educación, Cultura y Deporte; Calle San Agustín, 5 - 3 Planta; 28014 Madrid; Tel. +34917748000; Fax +34917748026; [email protected]

Dietary total antioxidant capacity from different assays in relation to serum C-reactive protein among young Japanese women

<p>Abstract</p> <p>Background</p> <p>The association between dietary total antioxidant capacity (TAC) from different assays and serum C-reactive protein (CRP) has not been assessed in non-Western populations. We examined the association between dietary TAC and serum CRP concentration in young Japanese women using different four TAC assays.</p> <p>Methods</p> <p>The subjects were 443 young Japanese women aged 18–22 years. Dietary TAC was assessed with a self-administered diet history questionnaire and the TAC value of each food using the following four assays: ferric reducing ability of plasma (FRAP); oxygen radical absorbance capacity (ORAC); Trolox equivalent antioxidant capacity (TEAC); and total radical-trapping antioxidant parameter (TRAP). Serum CRP concentrations were measured by highly sensitive nephelometry.</p> <p>Results</p> <p>The major contributor to dietary TAC was green, barley, and oolong tea (FRAP: 53%, ORAC: 45%, TEAC: 36%, and TRAP: 44%). The prevalence of elevated CRP concentrations (≥ 1 mg/L) was 5.6%. TAC from FRAP was inversely associated with serum CRP concentrations (adjusted odds ratio [OR] for elevated CRP concentration in high [compared with low] dietary TAC group: 0.39 [95% confidence interval (CI): 0.16-0.98]; <it>P</it> = 0.04). TAC from ORAC was inversely associated with CRP, although the association was not significant (OR: 0.48 [95% CI: 0.20-1.14]; <it>P</it> = 0.10). TAC from TEAC was inversely associated with CRP (OR: 0.32 [95% CI: 0.12-0.82]; <it>P</it> = 0.02), as was TAC from TRAP (OR: 0.31 [95% CI: 0.12-0.81]; <it>P</it> = 0.02).</p> <p>Conclusions</p> <p>Dietary TAC was inversely associated with serum CRP concentration in young Japanese women regardless of assay. Further studies are needed in other populations to confirm these results.</p
