This study aimed to determine the percentage of Exercise-Induced Pulmonary Hemorrhage (EIPH) by endoscopic evaluation after racing in Thoroughbred horses. A total of 172 horses between 2 to 8 years old (75 females and 97 males) at Monterrico racetrack in Lima were used. The endoscopic tracheal evaluation was done between 30 and 90 minutes of rest after the race. The animals that had blood in the trachea were considered positive. The results showed that 59.9% of the horses were positive to EIPH, but without significant differences due to sex and type of race track.

El objetivo del presente estudio fue determinar el porcentaje de presentación de Hemorragia Pulmonar Inducida por Ejercicio (HPIE) mediante examen endoscópico en caballos Pura Sangre de Carrera después de realizada una competencia. Se utilizó 172 caballos de 2 a 8 años de edad (75 hembras y 97 machos) del Hipódromo de Monterrico de Lima. La evaluación endoscópica traqueal fue realizada entre los 30 y 90 minutos de reposo posteriores a la carrera. Los animales con sangre en la tráquea fueron considerados positivos. El 59.9% de animales fue positivo a HPIE, sin haber diferencias significativas en la presentación de HPIE entre sexos y tipos de pista de carrera.

Study Objectives Assess acute changes in nocturnal sleep oxygenation, sleep disordered breathing and symptoms of Acute Mountain Sickness (AMS) in healthy High Altitude (HA) sojourners. Methods Ten subjects born at Sea Level (SL) were enrolled and underwent nocturnal polygraphy for 5 consecutive nights at HA and 2 nights before and after HA (2761 m). Nocturnal oxygen profiles were characterized by the mean Oxyhaemoglobin Saturation (SpO2) during sleep, and sleep apnea severity was represented by the Apnea-Hypopnea Index (AHI). Repeated measures linear regression was used to examine responses in outcome variables (SpO2, logAHI and LLS) between HA and SL. Mean SpO2 on night 1 at HA was used to stratify post-hoc analyses based on mean level of nocturnal desaturation and logAHI. Subjects completed the Lake-Louise Score (LLS) survey every day. Results Compared to SL, mean SpO2 was lower at HA ...
