Efficacy of a Modified Live Virus Vaccine against Porcine Reproductive and Respiratory Syndrome Virus 1 (PRRSV-1) Administered to 1-Day-Old Piglets in Front of Heterologous PRRSV-1 Challenge.

PRRSV is one of the most important viruses in the global swine industry and is often controlled by the use of modified live virus (MLV) vaccines. This study assessed the impact of a PRRSV-1 MLV vaccine applied to 1-day-old piglets challenged on day 28 of life with a PRRSV-1 field isolate (AUT15-33). Twenty-one piglets were vaccinated within 24 h of birth (T02), whereas 20 piglets were left unvaccinated (T01).

Does the modelling of the pectus bar affect its stability? Rationale for using a short flat bar.

Objectives: Although the Nuss procedure for pectus excavatum is still associated with a non-negligible risk of postoperative bar displacement, the potential effects of the length and shape of the bar on its corrective ability and stability have not been sufficiently studied. The aim of this study was to determine how the modelling of the pectus bar affects its stability and whether an alternative configuration of the implant can improve clinical success.

Methods: Simulated implantation of bars with different shapes and sizes in a computational model was carried out.

Selective packing for uncontrollable traumatic thoracic wall bleeding preserving cardiopulmonary function.

Background: Uncontrollable chest wall bleeding secondary to thoracic trauma has been a challenging problem faced by surgeons. Thoracic packing has been described as a good alternative although most thoracic surgeons avoid it because of the potential deleterious effects on cardiopulmonary function.

Methods: We describe a selective gauze packing technique of the thoracic wall preserving cardiopulmonary function in 3 patients with uncontrollable bleeding, where gauze packs were placed on bleeding areas holding them in a "sandwich-like" arrangement between the skin and the pleura and tightly fixed with coated wire stitches using internal and external-thoracic Ventrofil® devices.

Proteomic analysis of outer membrane proteins and vesicles of a clinical isolate and a collection strain of Stenotrophomonas maltophilia.

Unlabelled: Stenotrophomonas maltophilia is a Gram-negative pathogen with emerging nosocomial incidence that displays a high genomic diversity, complicating the study of its pathogenicity, virulence and resistance factors. The interaction of bacterial pathogens with host cells is largely mediated by outer membrane proteins (OMPs). Indeed, several OMPs of Gram-negative bacteria have been recognized as important virulence factors and targets for host immune recognition or to be involved in mechanisms of resistance to antimicrobials.
