A new study from Avicenna University Hospital in Marrakesh demonstrates that the plethysmographic perfusion index (PPI), a non-invasive measure derived from standard pulse oximeters, can help guide fluid therapy in critically ill patients with acute circulatory failure. Using a 500-mL fluid challenge in 50 ICU patients, researchers found that changes in PPI after the bolus accurately identified those likely to benefit from additional fluids, offering a low-cost, accessible tool for safer resuscitation.

Regular follow-up is necessary after endovascular aneurysm repair to detect possible endoleaks. In a recent breakthrough, researchers from Hanyang University have recently developed a novel ultrathin, flexible, wireless, and implantable sensor for continuous monitoring of blood leakage. Their technology has the potential to become the new standard of care for aneurysm treatment, enabling timely intervention and highly enhanced postoperative outcomes.
