Comparison of wave overtopping estimation models for urban beaches. Towards an early warning system on the Basque coast.

This study compares the performance of different wave overtopping estimation models at urban beaches. The models selected for comparison are the Mase et al. (2013) and EurOtop parametric models and the XBeach process-based model in surfbeat and non-hydrostatic mode. Seven energetic storms are selected between 2015 and 2022 with offshore significant wave height ranging between 3 m and 8 m and peak period between 12 s and 20 s to perform the model comparison. The information required to run and validate the models (beach slope, shoreface shape, absence/presence of overtopping) was collected for each storm from coastal videometry. To account for the uncertainties derived from the incident waves randomness and the bathymetry shape when using the process-based model, a series of simulations with random seed boundary conditions were run over two different realistic profile shapes for each storm. The present study is a pilot study on the beach of Zarautz; however, it can be extended to other beaches of the Basque coast. Results indicate that while Mase et al. (2013) and EurOtop tend to reasonably predict the absence or presence of overtopping events, they tend to underestimate the hazard level at the beach of Zarautz. Additionally, the beach underwater profile shape can affect the process-based model performance at intermediate intensity storms and to a lesser extend during moderate storms. Finally, the hazard level at the beach of Zarautz varies significantly alongshore due to the configuration of the seawall, highlighting the need for local adaptation measures. Considering that there is no model that systematically performs better than others, it might be reasonable to use model assemble techniques to draw conclusions from a probabilistic perspective.

Síndrome de May-Thurner, diagnóstico y tratamiento: a propósito de un casol / May-Thurner syndrome, diagnosis and treatment: a case report

Según la evidencia científica, la trombosis venosa profunda (TVP) se trata con anticoagulación, variando el tiempo según la causa. Ocasionalmente aparecen recidivas en la misma localización, siendo el síndrome de May-Thurner o síndrome de Cockett una de las causas, debido a la compresión del sistema venoso ilio-cava entre los cuerpos vertebrales y el sistema arterial. El tratamiento varía respecto al resto de causas de TVP: aunque la anticoagulación debe mantenerse el mismo tiempo, en estos casos está recomendada la trombectomía, con o sin la colocación de stent venoso para evitar la recidiva. No existe consenso en la literatura respecto a la indicación o no de antiagregación tras el periodo de anticoagulación. Presentamos un caso de síndrome de May-Thurner tratado con trombectomía y colocación de stent venoso, que resultó un manejo óptimo de la enfermedad

According to scientific evidence, deep venous thrombosis (DVT) is treated with anticoagulation therapy, involving different periods of time depending on the cause. Occasionally, recurrences appear in the same location, with May-Thurner syndrome or Cockett syndrome as one reason, due to compression of the ilio-cava venous system between the vertebral bodies and the arterial system. In these cases, anticoagulation therapy must be maintained during the same time as in the rest of DVT, but as opposed to them, thrombectomy is recommended, with or without the implant of a venous stent in order to avoid recurrence. There is no consensus in the literature regarding the indication of antiaggregation therapy after the anticoagulation therapy period. We present a case of May-Thurner syndrome treated with thrombectomy and the implant of a venous stent, which yielded an optimum management of the disease
