Validity of the ROX index in predicting invasive mechanical ventilation requirement in pneumonia.

Background: The ROX index (espiratory rate-ygenation) has been described as a prediction tool to identify the need for invasive mechanical ventilation (IMV) in community-acquired pneumonia (CAP) with acute hypoxaemic respiratory failure treated with high-flow nasal cannula in order to avoid delay of a necessary intubation. However, its use in predicting the need for ventilatory support in hospitalised patients with CAP has not been validated.

Methods: This is a retrospective cohort study including subjects with CAP treated in the general ward, emergency service or intensive care unit of a third-level centre in Cundinamarca, Colombia, between January 2001 and February 2020.

Septic emboli from pyomyositis.

Pyomyositis commonly presents with fever, muscle pain and abscess formation involving deep soft-tissue compartments. is the main causative organism and diagnosis is usually established clinically, supported by imaging, but confirmation may be achieved by histopathological examination. Broad-spectrum antibiotic therapy and surgical debridement are the cornerstone of treatment.
