Background: The purpose of this study was to assess the prevalence of coma among patients in critical care units in Chile. We also aimed to provide insight into the demographic characteristics, etiologies, and complications associated with coma.
Methods: A single day cross-sectional study was conducted through a national survey of public and private hospitals with critical and intensive cardiac care units across Chile.
Pasteurella multocida is a gram-negative coccobacillus bacterium found as a commensal in the oropharynx of domestic animals such as cats and dogs and some farm animals. Soft tissue infections and occasionally bacteremia in immunocompromised patients with direct contact with animals are described. We report a 61 year old male with a history of scratches and close contact with domestic cats, with a septic shock originating from a pulmonary focus, requiring mechanical ventilation and vasopressors.

These effects are associated with an improved ventilatory ratio and reduction in the partial pressure of carbon dioxide (PaCO). However, these physiological effects have not been completely studied, and their mechanisms have not yet been elucidated.

- - Surface chemistry is crucial for determining the properties of gold nanoparticles (AuNPs), and traditional methods for modifying these surfaces often involve complex place-exchange reactions with new ligands.
- - A new methodology has been developed that modifies AuNPs by acylating terminal amino groups of PEG ligands using organic acid anhydrides in a simple aqueous buffer.
- - This approach not only allows for complete surface modification but also enables the creation of AuNPs with mixed surface chemistries, making it a more efficient and versatile alternative to existing methods for customizing AuNP surfaces.
