    Crotalus enyo is a rattlesnake endemic to Baja California peninsula, Mexico. The natural history of this species is poorly known, so the goal of this study was to determine the diet of C. enyo in the Cape Region, an area with different conditions than the rest of the peninsula. We analyzed the stomach contents of 24 specimens obtained during 2010-2013, and identified the ingested prey. The diet of C. enyo consists of rodents (83.34%) and lizards (16.66%), although presents a diverse diet, the data suggest C. enyo is a specialist predator at Cape Region. We didn’t find differences in diet composition between sexes, site of capture, or season. This study documents three new prey items in the diet of C. enyo: the Orange-Throated Whiptail (Aspidocelis hyperythra), the Cape Spiny-Tailed Iguana (Ctenosaura hemilopha) and Hunsaker’s Spiny Lizard (Sceloporus hunsakerii)

    Mexico, Zacatecas, Municipality of Valparaiso, ca. 2 km (airline) west of San Juan Capistrano, (22.637258° N; 104.118608° W [WGS84]; 1249 m elevation), 18 July 2017. Collected by Jorge A. Bañuelos-Alamillo. The snake was deposited in the Vertebrate Collection at Universidad Autónoma de Aguascalientes (CZUAA-REP-690); a photo voucher is also available at the San Diego Natural History Museum (SDSNH_HerpPC_05366). Adult female (SVL= 900 mm, TL= 380 mm), and had 17 midbody dorsal scales, 188 ventral scales, 106 subcaudals, nine supralabials, 11 infralabials, two loreal scales, one preocular, and three postoculars on both sides (Fig. 1-A). The snake was road-killed near a river within dry forest vegetation and had recently consumed an adult male Aspidoscelis gularis scalaris ingested headfirst.Asociación Herpetológica Argentin

    Objetivo: Evaluar la aparición de reflujo gastroesofágico (RGE) posterior a gastrectomía en manga como manejo para la obesidad, con el Gastroesophageal Reflux Disease Questionnaire (GerdQ). Método: Estudio retrospectivo de pacientes llevados a gastrectomía en manga durante 2016 y 2017, habiendo descartado RGE con endoscopia digestiva alta prequirúrgica, y evaluación posoperatoria con la escala GerdQ. Resultados: Se incluyeron en el estudio 129 pacientes, con un promedio de edad de 45 años, el 77.5% de sexo masculino y como comorbilidad más frecuente hipotiroidismo (25.6%) e hipertensión arterial (23.3%). El 12.4% tenían un puntaje ≥ 8, 14 eran mujeres y 2 hombres, y no hubo relación estadísticamente significativa con el índice de masa corporal preoperatorio. Conclusiones: Estandarizar la técnica de manga gástrica en los servicios de cirugía bariátrica, teniendo en cuenta los factores técnicos asociados a RGE posoperatorio de novo, disminuye la aparición de RGE según lo evaluado por la escala GerdQ.Objective: To evaluate the appearance of gastroesophageal reflux in our population after sleeve gastrectomy as management for obesity, with the Gastroesophageal Reflux Disease Questionnaire (GerdQ). Method: Retrospective study of patients undergoing sleeve gastrectomy during 2016 and 2017, having ruled out gastroesophageal reflux (GER) with pre-surgical upper digestive endoscopy, and post-operative evaluation with the GerdQ scale. Results: 129 patients were included in the study, average age was 45 years, gender of greater male appearance was 77.5%, the most frequent comorbidities were hypothyroidism 25.6% and hypertension 23.3%. 12.4% had a score greater than or equal to 8, 14 were women and 2 men, there was no statistically significant relationship with the preoperative mass index. Conclusions: Standardizing the gastric sleeve technique in the bariatric surgery services, taking into account the technical factors associated with post-operative GERD de novo, decreases its appearance as evaluated by the GerdQ scale
