Notes sobre la neotectònica al Vallès Oriental

Hi són descrits tot un seguit d'aspectes del modelat detallat del Valles Oriental associats a moviments del substrat. Aquests moviments del substrat són relacionables amb el funcionament recent de les falles pertanyents als dos sistemes de fractures, aproximadament ortogonals, presents al socol de la Depressió del Valles

Sobre la Geomorfologia del Vallès Oriental

Aquest treball és I'exposició dels principals resultats obtinguts a través de la cartografia geomorfològica, a escala 1:25.000, d'un sector del Vallès Oriental (nord-est de la Península Ibérica). S'hi adjunta, a més, un esquema geomorfològic.Hom hi descriu les formes, les formacions superficials i les alteracions correlatives a I'evolució del relleu del Vallès durant el Quaternari, que s'iriterpreten a la llum de les recents hipòtesis de I'evolució geomorfològica quaterniària de la Mediterrània occidental.En el domini de la dinàmica actual es ressenyen els efectes sobre el modelat dels diferents tipus de processos actuants, amb un petit comentari drls llits fluvials.Finalment s'hi fa una sèrie d'observacioris que fan sospitar l'actuació de la neotectònica recent a l'àrea estudiada

La cartografía geomorfològica de Catalunya anterior a 1979

En este trabajo se presenta un inventario comentado de los documentos cartográficos geomorfológicos relativos a la Cataluña española. En la primera parte se han reunido las consideraciones metodológicas de diversos autores y especialmente los acuerdos de la Subcomisión de Cartografía Geomorfológica de la I. G. U.La segunda parte está dedicada a establecer un sistema de clasificación de los documentos geomorfológicos cartográficos, siguiendo las ideas de los autores más destacados en este campo. (...

Effects of pre-operative isolation on postoperative pulmonary complications after elective surgery: an international prospective cohort study an international prospective cohort study

We aimed to determine the impact of pre-operative isolation on postoperative pulmonary complications after elective surgery during the global SARS-CoV-2 pandemic. We performed an international prospective cohort study including patients undergoing elective surgery in October 2020. Isolation was defined as the period before surgery during which patients did not leave their house or receive visitors from outside their household. The primary outcome was postoperative pulmonary complications, adjusted in multivariable models for measured confounders. Pre-defined sub-group analyses were performed for the primary outcome. A total of 96,454 patients from 114 countries were included and overall, 26,948 (27.9%) patients isolated before surgery. Postoperative pulmonary complications were recorded in 1947 (2.0%) patients of which 227 (11.7%) were associated with SARS-CoV-2 infection. Patients who isolated pre-operatively were older, had more respiratory comorbidities and were more commonly from areas of high SARS-CoV-2 incidence and high-income countries. Although the overall rates of postoperative pulmonary complications were similar in those that isolated and those that did not (2.1% vs 2.0%, respectively), isolation was associated with higher rates of postoperative pulmonary complications after adjustment (adjusted OR 1.20, 95%CI 1.05–1.36, p = 0.005). Sensitivity analyses revealed no further differences when patients were categorised by: pre-operative testing; use of COVID-19-free pathways; or community SARS-CoV-2 prevalence. The rate of postoperative pulmonary complications increased with periods of isolation longer than 3 days, with an OR (95%CI) at 4–7 days or ≥ 8 days of 1.25 (1.04–1.48), p = 0.015 and 1.31 (1.11–1.55), p = 0.001, respectively. Isolation before elective surgery might be associated with a small but clinically important increased risk of postoperative pulmonary complications. Longer periods of isolation showed no reduction in the risk of postoperative pulmonary complications. These findings have significant implications for global provision of elective surgical care.
