ABSTRACT
A 5-month-old, intact male, yellow Labrador retriever was presented with a 24-hour history of anorexia and vomiting. Abdominal imaging revealed the presence of a mechanical obstruction in the jejunum and peritoneal effusion. Cytologic evaluation and culture of the effusion prior to surgery identified a suppurative exudate with bacteria consistent with septic peritonitis and suspected to be related to the intestinal lesion. An exploratory laparotomy was performed, and a segment of jejunum was circumferentially severely constricted by an off-white, fibrous band of tissue. Resection and anastomosis of the strangulated segment of jejunum and excision of the constricting band provided resolution of the clinical signs. The dog made a complete recovery. Histologic evaluation revealed the band to be composed of fibrovascular and smooth muscle tissue, consistent with an idiopathic anomalous congenital band. No other gastrointestinal lesions were observed, either grossly at surgery or histologically in the resected segment of intestine. To our knowledge, a similar structure has not been reported in the veterinary literature.Copyright © 2022 Canadian Veterinary Medical Association. All rights reserved.
ABSTRACT
Analizamos el efecto del cese de la competición por COVID-19 en el rendimiento físico de jugadores de fútbol de la 1ª división española). La muestra se estratificó en tres grupos: rondas 1ª-3ª;25ª-27ª y 28ª-30ª. Las comparaciones por pares fueron Student-t y Mann-Whitney U. Usamos un valor p de ≤0.05 como criterio para la significación estadística. Los valores de umbral para evaluar las magnitudes del tamaño del efecto se realizaron a través (d de Cohen). Tras el parón, las distancias recorridas aumentaron en los equipos locales y visitantes. Hubo un ligero descenso de los esfuerzos de alta intensidad entre el post-confinamiento y las jornadas (25ª-27ª). Comparados el 1er y 3erperiodo, los valores fueron ligeramente superiores (rondas 28ª-30ª). Eso mismo se observó en las de aceleraciones y desaceleraciones, con mayores diferencias entre los periodos (1º y 3º). Hubo diferencias, cuando se comparó la reanudación con las jornadas previas al parón. PALABRASCLAVE: Covid-19, Fútbol, Alto Rendimiento, Parámetros Físicos.Alternate : We analyzed the effect of the cessation of competition for COVID-19 on the physical performance of soccer players in the 1st Spanish division). The sample was stratified into three groups: 1st-3rd rounds;25th-27th and 28th-30th. Pairwise comparisons were Student-t and Mann-Whitney U. We used a p-value of ≤0.05 as the criterion for statistical significance. Threshold values for evaluating effect size magnitudes were made using (Cohen's d). After the break, the distances traveled increased for the local and visiting teams. There was a slight decrease in high intensity efforts between post-confinement and the days (25th-27th). Comparing the 1stand 3rd period, values were slightly higher (rounds 28-30). The same was observed in those of accelerations and decelerations, with greater differences between the periods (1st and 3rd). There were differences when the resumption was compared with the days before the break.
