Cecal appendix adenocarcinoma occurs in approximately 0.1% to 0.2% of all appendectomies. One subtype, mucinous adenocarcinoma, represents 0.08% of all neoplasms. Diagnosis is usually incidental and surgery is the best treatment option. We describe the case of a 55-year-old male patient, evaluated for severe pain in the right iliac fossa, who was found to have an appendiceal mass during open appendectomy. A fragmented appendix measuring 7 x 1.8 x 0.8cm, with mucoid content in its lumen; as well as mucin pools in more than 50% of the sample and signet ring cells in light microscopy, revealed the pathological diagnosis of mucinous adenocarcinoma. Therefore, the pathological analysis of surgical pieces is transcendental, since there are infrequent diagnoses that can change the prognosis and course of clinical management of a patient.

Guillain-Barré Syndrome (GBS) is a rare disorder of the nervous system, where the patient's immune system attacks the peripheral nerve cells in the arms and legs, causing muscle weakness, loss of sensation and sometimes total paralysis. The origin of this disorder has been associated with immune responses triggered by post-infection with Campylobacter spp. However, when there is no obvious cause of the disease, it is usually not investigated due to the greater interest in the treatment. Therefore, most cases are reported as idiopathic origin. Between January and March 2016 worldwide, GBS outbreaks were reported in 8 countries, linked to the emergence of the Zika virus. In Peru, since the end of 2018, outbreaks of GBS have been reported more frequently and although no association with Zika has been confirmed, the increase in cases, the geographical extension where they occurred and the clinical characteristics of affected patients, have common patterns that lead to suspect an infectious origin mainly of viral type. Therefore, it is important to know the current scientific evidence about the role that some viruses play in this syndrome, allowing us to expand our epidemiological picture with new tools to address this disease

La Cooperación Transfronteriza (CT) alcanza actualmente un protagonismo como no había alcanzado en otro momento histórico. Bajo esta perspectiva, la necesidad de identificar factores críticos para lograr el éxito territorial es fundamental mediante estrategias de CT que conduzcan a una mejora de la calidad de vida de las poblaciones residentes. El objetivo principal de este trabajo es analizar las eurociudades luso-españolas. Este estudio enfatiza, la necesidad de articular un proyecto conjunto entre actores de ambos lados de la frontera, pero en el que la participación de la población local, también sea considerado un factor fundamental, entre tantos otros que se deben tener en cuenta para que se alcance el éxito de dicho proyecto. Además, este trabajo presenta una novedad para la literatura temática al sacar a la luz cómo estos proyectos de CT de eurociudades evolucionaron, y podrían ser la nueva tendencia y catalizador del desarrollo territorial sostenible en sus regiones.

Entre 2017 e 2019 elaborouse a Estratexia do Río Miño Transfronteirizo. Trátase dun documento realizado a través de mecanismos participativos para o territorio abranguido polo Agrupamento Europeo de Cooperación Territorial (AECT) Río Miño, na raia húmida galegoportuguesa. Debátese aquí esta iniciativa en relación cos presupostos teórico-conceptuais xerais da ordenación territorial e, máis en concreto, da que se tenta implantar en contextos fronteirizos cunha óptica deliberadamente transfronteiriza. A metodoloxía é a da investigación-acción participante. Os resultados estrutúranse mediante tres períodos estabelecidos a efectos analíticos e discursivos, cada un dos cales culminou en cadansúa versión do plan de acción estratéxico. Valóranse os cambios producidos entre as tres versións sucesivas. Agás no relativo ao sector turístico, a dimensión económica foi perdendo peso. En paralelo, acadaron maior relevancia os aspectos de gobernanza. Asemade, detéctase unha tensión constante entre dous ámbitos territoriais presentes no seo do AECT.

La existencia de intensas relaciones de cooperación entre las regiones de Galicia y Norte de Portugal desde principios de la década de 1980 han conducido a la creación de una eurorregión para coordinar acciones conjuntas en busca de su mutuo desarrollo. La cuestión de si la existencia de estas fuertes acciones de cooperación entre regiones transfronterizas contribuye a la reducción de desigualdades entre ambos lados de la frontera y a una convergencia permanece sin esclarecerse. Por ello, el objetivo del presente análisis es contribuir a esta discusión, explorando el fenómeno de convergencia en la Eurorregión Galicia-Norte de Portugal durante el periodo de 1980 a 2019. Los resultados muestran una reducción en dichas desigualdades económicas a lo largo de todo el periodo y una convergencia absoluta al mismo nivel económico, demostrándose que la cooperación entre las regiones de la eurorregión ha conducido a un proceso de cohesión.

Despite decades of European financial stimulation for cross-border projects, the attention for cross-border cooperation (CBC) is still volatile. The focus on CBC has been fluctuating for decades, depending on political and economic trends among other aspects. Irrespective of that, it remains difficult to encourage citizens in the Dutch-German borderland to engage in cross-border working and living. Without commitment among citizens at grassroots level, CBC will primarily remain an enjoyable pastime for the euroregional elite. Based on scientific debates on border studies, this paper highlights CBC by reflecting on border-related policy. By way of illustration, this research will zoom in on the northern Meuse-Rhine Euroregion, one of the Dutch-German Euroregions. Based on some contemplations on Dutch-German cooperation in recent decades, this article concludes with some action-oriented principles for CBC which could contribute to strengthening its impact.

The term “España Vaciada” has recently been coined to define the long-term trend of depopulation in Spain´s inland areas. It has gained traction as it spilled over from a local issue to the national agenda. At the same time, the European Union has made steps to give greater prevalence to the topic of demographic decline. This article maps out and provides a narrative of the failed attempts of territorial mobilisation around this issue since 2016. It examines a number of territorial actors as they try to are shape both Spain´s Demographic strategy against demographic decline as well as their rent-seeking efforts towards EU Cohesion Policy post 2020 by way of maps and a novel definition. They try to address the same territorial challenge, the growing depopulation of vast areas of inland Spain, but are unable to coalesce around common solutions due to their different priorities and approaches.

El artículo aborda la definición de las eurorregiones en un contexto de cooperación transfronteriza que favorece las tres dimensiones de la cohesión: económica, social y territorial. Con un enfoque descriptivo, el objetivo del trabajo es situar las eurorregiones en el contexto actual, en el que se enfrentan a dos retos importantes: por un lado, la necesidad de unos niveles de gobernanza similares que favorezcan la toma de decisiones a un lado y otro de la frontera, y por otro, las trabas jurídicas en relación con la movilidad y con la actividad económica que las restricciones derivadas de la covid-19 han puesto de relieve. Los fondos europeos constituyen una oportunidad de resiliencia para todos estos territorios. Para los que, a pesar de compartir el hecho fronterizo, se concluye la dificultad de establecer una única hoja de ruta, dada la diversidad tanto geográfica como socioeconómica.

Esta investigação teve como objetivo principal compreender como é que as histórias contadas na comunicação das marcas associadas à causa COVID-19, influenciaram o engagement com os seus consumidores. Relativamente às histórias avaliou-se o enredo, as personagens e a verosimilhança. No que diz respeito ao consumer engagement (CE), o envolvimento afetivo, emocional e cognitivo. Este estudo contou com uma metodologia qualitativa e um método baseado na netnografia que teve em consideração os comentários dos anúncios publicados em duas redes sociais, o Facebook e o Instagram, por nove marcas portuguesas. Os resultados desta pesquisa revelam que para as histórias, associadas à COVID-19, terem um maior nível de influência no consumidor, devem utilizar os seus elementos como um todo, para gerar um engagement positivo no consumidor.
