Literature reveals evidence that prone positioning can improve the oxygenation of critically ill patients suffering from acute lung injury or acute respiratory distress syndrome. Multicentre evidence, however, does not support the claim that it improves patients' outcome. The implementation of multiprofessional guidelines by which to direct the manoeuvre will facilitate the safe and effective management of patients in the prone position. They will thus heighten multiprofessional awareness of the technique and promote its proactive use at such time so as to achieve maximum clinical benefit.

Monitoring response to prone positioning.

Purpose Of Review: The increasing use of prone position, in intubated patients with acute respiratory distress syndrome as well as in patients with acute hypoxemic respiratory failure receiving noninvasive respiratory support, mandates a better definition and monitoring of the response to the manoeuvre. This review will first discuss the definition of the response to prone positioning, which is still largely based on its effect on oxygenation. We will then address monitoring respiratory and hemodynamic responses to prone positioning in intubated patients.

Vesicles play critical roles in cellular materials storage and signal transportation, even in the formation of organelles and cells. Natural vesicles are composed of a lipid layer that forms a membrane for the enclosure of substances inside. Here we report a coacervate vesicle formed by the liquid-liquid phase separation of cholesterol-modified DNA and histones.

Background: Aneurysmal bone cysts (ABCs) are slow-growing, expansile bone tumors most often observed in the long bones and lumbar and thoracic spine. Anterior column ABCs of the spine are rare, and few cases have described their surgical management, particularly for lesions with extension into the odontoid process and the bilateral C2 pedicles. In the present case, the authors describe a two-stage strategy for resection of a symptomatic 2.

Background: Vascularized bone grafts (VBGs) are currently the main surgical option for the restoration of humeral bone defects particularly when defects are larger than 6 cm. Because it offers a strong, rapid blood supply, VBGs easily integrate into the recipient sites and undergo active resorption and remodeling into healthy bone through primary bone healing. Additionally, they support the recipient site's immune system in preventing and reducing infection.

Introduction: Endoscopic spine surgery (ESS) is a minimally invasive technique that allows for direct visualization of spinal pathologies and has become a safe and effective alternative to traditional open spine surgery. Conventionally performed in the prone position, biportal endoscopy can also be done in the lateral position to avoid prone-associated complications. To our knowledge, the use of unilateral biportal endoscopy (UBE) in the lateral position has not been previously reported.
