Chronic cerebral arterial occlusion and moyamoya disease are significant causes of stroke, particularly in regions where advanced diagnostic tools are limited. This study from Rajavithi Hospital assessed a simple bypass protocol that uses mean transit time to identify candidates for single-barrel bypass surgery. Thirty patients were evaluated, and 80 percent showed postoperative improvement with high graft patency and minimal complications. The findings support mean transit time as an effective non-stress method for guiding surgical decision-making.

Hypertrophic chondrocytes are deeply involved in the growth of mammalian bones. Researchers find that these cells transform into multiple functional cell types, including those responsible for lengthening bones, maintaining the periosteum, and promoting the invasion of blood vessels that supply newly formed bone. Thrombospondin-4, a key signaling molecule produced by these cells, drives blood vessel formation. These findings open new avenues for enhancing bone repair and healing injured bones.

Real-time monitoring of patient-ventilator asynchrony (PVA) and respiratory parameters is important in patients with severe pneumonia. In a recent study, researchers have developed a “Remote Ventilate View” platform, which automatically analyzes ventilator waveforms in real-time, identifies eight PVA subtypes, and calculates the overall asynchrony index. This represents a paradigm shift from qualitative, spot-check assessments to precise quantification and longitudinal monitoring of PVA throughout the entire ventilation course.
