Abstract
Metal-based drugs currently dominate the field of chemotherapeutic agents; however, achieving the controlled activation of metal prodrugs remains a substantial challenge. Here, we propose a universal strategy for the radiation-triggered activation of metal prodrugs via nanosurface energy transfer (NSET). The core-shell nanoplatform (Ru-GNC) is composed of gold nanoclusters (GNC) and ruthenium (Ru)-containing organic-inorganic hybrid coatings. Upon X-ray irradiation, chemotherapeutic Ru (II) complexes were released in a controlled manner through a unique NSET process involving the transfer of photoelectron energy from the radiation-excited Ru-GNCs to the Ru-containing hybrid layer. In contrast to the traditional radiation-triggered activation of prodrugs, such an NSET-based system ensures that the reactive species in the tumor microenvironment are present in sufficient quantity and are not easily quenched. Additionally, ultrasmall Ru-GNCs preferably target mitochondria and profoundly disrupt the respiratory chain upon irradiation, leading to radiosensitization by generating abundant reactive oxygen species. Consequently, Ru-GNC-directed radiochemotherapy induces immunogenic cell death, resulting in significant therapeutic outcomes when combined with the programmed cell death-ligand 1 (PD-L1) checkpoint blockade. This NSET strategy represents a breakthrough in designing radiation-triggered nanoplatforms for metal-prodrug-mediated cancer treatment in an efficient and controllable manner.

Abstract
BACKGROUND Cardiovascular diseases are the most common non-obstetric cause of maternal death. These cases became more common thanks to the improvement in cardiovascular therapies. A multidisciplinary team is necessary to manage these pregnancies. CASE REPORT A 32 years old women at the 25th week of gestation for acute heart failure in pre-existing left ventricular dysfunction induced by radio-chemotherapy admitted to the Coronary Unit of IRCCS Policlinico Universitario Agostino Gemelli for worsening of dyspneic symptoms and anuria not responding to diuretic therapy. At the echocardiogram: ejection fraction 30%, enlarged left atrium, systolic pulmonary arterial pressure 38 mmHg, bilateral pleural effusion, bilateral diffused pulmonary B lines. A multidisciplinary team composed by cardiologists, gynecologists, anesthesiologists, cardiac surgeons, neonatologists and bioethicists decided for an elective cesarean delivery at the 27th week of gestation in the hybrid cardio-thoracic operating theater. Anesthesia was provided by combined spinal-epidural technique under invasive continuous hemodynamic monitoring with the Edwards Lifesciences HemoSphere with Hypotension Prediction Index (HPI) and ForeSight technology (Edwards Lifesciences, Irvine, USA) through catheterization of the left radial artery. The femoral arteries were left available for extracorporeal circulation. Continuous norepinephrine infusion was started once liquor was collected in the spinal needle at a 0.1 mcg/kg/minute through a central line and was continued until the end of surgery. Fluid management consisted of a total of 200 ml of crystalloids. HPI values never reached alarm values (maximum value =10). The patient was discharged home on the 5th day after delivery with good hemodynamic compensation. The baby was intubated at birth and then gradually weaned from mechanical ventilation, then discharged.
