Description of a new species of the Anastrepha curvicauda species group (Diptera: Tephritidae)

Las moscas del género Anastrepha, se consideran plagas de gran importancia económica, no solo por el daño directo que causan a la producción de fruta sino, también, por las restricciones de cuarentena impuestas a los países exportadores de fruta. Por lo tanto, preparar descripciones y generar herramientas de identificación taxonómica, que permitan un reconocimiento adecuado y oportuno de las especies de importancia agrícola, es una actividad básica para la sanidad de las plantas en los países productores y exportadores de frutas. En este trabajo, se describe e ilustra Anastrepha ligiae, una nueva especie del grupo Anastrepha curvicauda, capturada con trampas McPhail, en los municipios de Albán y Anolaima (Cundinamarca) y Vélez (Santander), Colombia y criados en la fruta de la papayuela Vasconcellea pubescens A. DC. (Caricaceae). V. pubescens, se registra por primera vez como una planta hospedante para el género Anastrepha.Fruit flies of the genus Anastrepha are considered pests of great economic importance because they do not only cause direct damage to the fruit production, but also due to the quarantine restrictions imposed to fruit exporting countries. Therefore, preparing descriptions and generating taxonomic identification tools that allow an appropriate and accurate recognition of the species of agricultural importance are basic plant health activities in the fruit producing and exporting countries. In this work, we describe and illustrate Anastrepha ligiae , a new species of the Anastrepha curvicauda group captured with McPhail traps in the municipalities of Albán and Anolaima (Cundinamarca) and Vélez (Santander), Colombia, and reared from mountain papaya Vasconcellea pubescens A. DC. (Caricaceae). V. pubescens is the first time recorded as a host plant of the genus Anastreph

Clinical practice guidelines for the diagnosis and treatment of patients with soft tissue sarcoma by the Spanish group for research in sarcomas (GEIS)

Soft tissue sarcomas (STS) constitute an uncommon and heterogeneous group of tumours, which require a complex and specialized multidisciplinary management. The diagnostic approach should include imaging studies and core needle biopsy performed prior to undertaking surgery. Wide excision is the mainstay of treatment for localized sarcoma, and associated preoperative or postoperative radiotherapy should be administered in high-risk patients. Adjuvant chemotherapy was associated with a modest improvement in survival in a meta-analysis and constitutes a standard option in selected patients with high-risk STS. In metastatic patients, surgery must be evaluated in selected cases. In the rest of patients, chemotherapy and, in some subtypes, targeted therapy often used in a sequential strategy constitutes the treatment of election. Despite important advances in the understanding of the pathophysiology of the disease, the advances achieved in therapeutic results may be deemed still insufficient. Moreover, due to the rarity and complexity of the disease, the results in clinical practice are not always optimal. For this reason, the Spanish Group for Research on Sarcoma (GEIS) has developed a multidisciplinary clinical practice guidelines document, with the aim of facilitating the diagnosis and treatment of these patients in Spain. In the document, each practical recommendation is accompanied by level of evidence and grade of recommendation on the basis of the available data
