Wild Ungulates Constitute the Basis of the Diet of the Iberian Wolf in a Recently Recolonized Area: Wild Boar and Roe Deer as Key Species for Its Conservation.

The Iberian wolf (Canis lupus signatus) is recolonizing historical distribution areas after decades of absence. As in other human-dominated landscapes, finding a balance to protect this species by favoring recolonization and mitigating human-wildlife conflicts is a challenge. Since wolves are often generalist opportunistic predators, we studied their diet composition in central Spain to evaluate the consumption of domestic ungulates and provide reliable data that could help local authorities to deal with the current wolf-cattle ranchers conflict and coexistence. Diet composition (% prey occurrence, % prey ingested biomass) was analyzed through the identification of prey hairs present in 671 scats collected between 2017 and 2021. The wolves fed more on wild ungulates (82% occurrence) than domestic ones (18%). Wild boar (Sus scrofa, 44% occurrence) and roe deer (Capreolus capreolus, 35%) were the most consumed prey. The wolves positively selected these two species. The wolves' diets varied between seasons, years, and forest regions, but a diet based on wild ungulates predominated over domestic ones. Food niche breadth showed variations depending on seasons and years. Preserving the availability and diversity of wild ungulates may favor reducing livestock attacks and would be an achievable goal that would help to conserve this species and reduce conservation conflicts.

Otras causas de dolor abdominal: síndrome de la arteria mesentérica superior / Other causes of abdominal pain: superior mesenteric artery syndrome

La clínica del síndrome de la arteria mesentérica superior se basa en los siguientes síntomas: dolor epigástrico postpandrial, saciedad temprana, náuseas o vómitos biliosos, sobre todo en pacientes con una pérdida significativa de peso reciente o con una intervención quirúrgica previa, en la mayoría de ocasiones por escoliosis. En nuestro trabajo presentamos el caso de un varón de 83 años con antecedentes de fibrilación auricular y EPOC e intervenido por colecistitis litiásica crónica y ulcus péptico, que acude al servicio de urgencias con dolor abdominal intenso junto con vómitos y ausencia de ventoseo y deposición. Debemos pensar en este síndrome una vez descartadas las causas más frecuentes de dolor abdominal. Mediante la sospecha clínica y la realización del TC conseguimos un diagnóstico temprano, y evitamos complicaciones posteriores como alteraciones electrolíticas, perforación gástrica o gas venoso portal

The symptoms of superior mesenteric artery syndrome are: postprandial epigastric pain, early satiety, nausea or bilious vomiting, particularly in patients with significant recent weight loss or with previous surgery, most often scoliosis. We present the case of an 83-year-old man with a history of atrial fibrillation and COPD and previous surgeries due to peptic ulcer and chronic calculous cholecystitis, who arrives in the Emergency Department with severe abdominal pain, vomiting, not passing gas and constipation. We must think about this syndrome once the most frequent causes of abdominal pain have been ruled out. Thanks to clinical suspicion and CT scan we can obtain an early diagnosis and avoid later complications such as electrolyte imbalance, gastric perforation or portal venous gas
