Penetrating thoracic injury requiring emergency pneumonectomy supported with two ECMO runs: A testament to multidisciplinary critical care medicine.

Post-traumatic pneumonectomies are uncommon and, if necessary, carry significant mortality. The use of extracorporeal membrane oxygenation (ECMO) for lung injury in trauma patient has demonstrated efficacy with minimal bleeding complications. We report a case of a young man with a penetrating thoracic injury that required a pneumonectomy supported with two separate ECMO runs for pulmonary failure postoperatively.

Contrasting nursery habitats promote variations in the bioenergetic condition of juvenile female red squat lobsters (Pleuroncodes monodon) of the Southern Pacific Ocean.

The red squat lobster Pleuroncodes monodon is an important fishery resource in the Humboldt Current System (HCS). This decapod is exploited in two fishing units: (a) the northern fishing unit (NFU, from 26°S to 30°S) and (b) the southern fishing unit (SFU, from 32°S to 37°S), each of which have an adjacent nursery area that is the source of recruits to replace the exploited adult populations (in the NFU: off the coast of Coquimbo (28°S) and in the SFU: off the coast of Concepción (36°S)). Marked spatial differences in the environmental conditions of the NFU and SFU, and the biogeographic break that exists between these nursery areas (30°S) may promote changes in the bioenergetic condition of new P. monodon juveniles. To evaluate this, we analyzed the bioenergetic condition (measured as: body mass, lipids, proteins, glucose, and energy) of new juvenile females in the main nursery areas off the Chilean coast. The juvenile females from the SFU showed a higher body mass than those from the NFU. Consistently, the juvenile females from the SFU had a higher content of lipids, proteins, and glucose than those from the NFU, indicative of higher energy contents and a higher lipid/protein ratio in the south compared to the north. Considering the current overexploitation of this fishery resource in the HCS, it is essential to understand how the bioenergetic condition of juvenile females of P. monodon may vary in nursery areas at different latitudes in order to generate sustainable fishery management policies with an ecological approach, designed specifically to each fishing unit. Furthermore, identifying the latitudinal variations of these biochemical compounds in P. monodon juveniles can elucidate the geographic origin of red squat lobsters that present a "better bioenergetic condition" in the HCS, which may significantly benefit sustainable fishing certification processes.

Parásitos gastrointestinales en cachorros caninos provenientes de la venta comercial en el Cercado de Lima / Gastrointestinal parasites in canine puppies for commercial sale in Lima downtown

Determinar la frecuencia de parásitos gastrointestinales en caninos menores de seis meses de edad provenientes de la venta comercial. También determinar si las variables raza, sexo y edad están asociadas a la presentación de cuadros de parasitosis. Metodología: Se recolectaron 97 muestras de heces de mascotas caninas que se comercializan en el cercado de Lima, las cuales fueron procesados mediante las técnicas de examen directo, de concentración por flotación, de concentración por sedimentación y de Ziehl Neelsen, considerándose positivas las muestras con presencia de huevos de parásito o parásitos bajo el microscopio. Resultados y Conclusiones: El 100% de las muestras analizadas fueron positivas a la presencia de parásitos. Las mayores frecuencias fueron del nemátode Toxocara canis fue (87.96%) y del protozoario Isospora canis (98.78%) ; los mismos como asociación biparasitaria (62.89%) y monoparasitarias Toxocara canis (17.56%); por primera vez se encontró una asociación de triprarasitismo de Toxocara canis - Isospora canis - Toxascaris leonina (12.37%). En los machos hubo una mayor presentación de parasitosis (57.7%) que en las hembras (42.3%). Caninos de raza pura tuvieron mayor frecuencia de presentación de parasitosis (82.5%); La edad no presentó diferencias estadísticas en los tres estratos estudiados, dándose en el estrato de mayor o igual que 8 y < 12 semanas representados por el 41.2% de casos. La parasitosis en caninos evaluados es del 100%, siendo Toxocara canis el más frecuente...

To determine the frequency of gastrointestinal parasites in canines younger that 6 months for commercial sale in Lima downtown. Methods: 97 dog fecal samples were analyzed using the techniques of direct examination, concentration by flotation, by sedimentation and Ziehl Neelsen, it was considered a positive sample the presence of parasites or parasite eggs under the microscope. Results and Conclusions: 100% of the samples tested were positive for the presence of eggs or parasites, where the nematode Toxocara canis (87.96%) and the protozoan Isospora canis (98.78%) were found more frequently; and both of them as biparasitism association (62.89%). Toxocara canis monoparasitism in (17.56%). Toxocara canis - Isospora canis - Toxascaris leonina (12.37%) triprarasitism association was found. In males there was a greater presence of parasites (57.7%) than females (42.3%). Pure breed had higher frequency of parasites (82.5%); Age does not show statistical differences in the three strata studied. 41.2% of cases were in the range of greater than or equal 8 and <12 weeks of age. The parasitism in the studied dogs is 100%, being the most common Toxocara canis...

Primer reporte de Neospora caninum, en caballos de carrera de Lima, Perú / First report of Neospora caninum, in race horse from Lima, Peru

Determinar la exposición de los caballos de carrera al N. caninum, mediante la detección de anticuerpos séricos. Material y Método: Se evaluaron 163 sueros de caballos procedentes del Hipódromo de Monterrico, Lima, los cuales fueron procesados mediante el método de Inmunoflorescencia Indirecta, considerándose positivos aquellos animales cuyos sueros obtuvieron un título igual o mayor a 1:100. Se realizó la titulación del suero mediante diluciones seriadas hasta alcanzar una dilución negativa. Resultados: Se detectaron anticuerpos a N. caninum en el 12 % (19/163) de los caballos examinados, 21% presentaron títulos de 1/100, 1/800 y 1/1600, el 6% presentaron títulos de 1/200 y 1/400 y el 5% presentaron títulos de 1/3200. No se encontró asociación entre las variables sexo, edad y procedencia con la presencia de seroreactores frente a N. caninum. Conclusión: El presente estudio es el primero en confirmar la presencia de anticuerpos séricos a N. caninum en caballos de carrera de Perú...

Determine the exposure of N. caninum in racehorses with the detection of serum antibodies. Material and methods: We evaluated sera from 163 horses from the Hippodrome of Monterrico, Lima, which were processed using the indirect immunofluorescence method, considering positive animals whose sera obtained a degree equal to or greater than 1:100. Was performed by titrating the serum dilutions to reach a negative dilution. Results: Antibody to N. caninum in 12% (19/163) of the horses examined, 21% had titers of 1/100, 1/800 and 1/1600, 6% had titers of 1/200 and 1/400 and 5% had titers 1/3200.
