Once again, Vall d'Hebron has been part of the 48H Open House BCN, an activity that gives citizens the opportunity to get first-hand knowledge of important city spaces and often inaccessible. During the weekend of October 26 and 27, more than 150 citizens have been able to discover the interior of the Surgical Bloc of the General Hospital, the Vall d'Hebron Research Institute (VHIR) and the Vall d'Hebron Oncology Institut (VHIO).The Surgical Block of the General Hospital is the installation that has received more groups of visits. In the hands of Dr. José Manuel Domínguez, the Surgical Coordinator, and Inmaculada Pueyo, the Nursing Supervisor of the block, the visitors were able to know inside the 10,000 square meters of installation and nineteen operating theaters in 2016 with a pioneering model in Europe that improves the flow of patients and professionals, clinical and operative efficacy and safety. The operating theaters incorporate neurosurge browsers, 3D imaging systems, integrated ultrasound and the new Da Vinci X robot. In addition, two of the nineteen operating rooms are hybrids, as they incorporate some X-ray surgical arcs to see the result directly of the intervention, designed for vascular surgery and neurosurgery.With regard to the VHIR, visitors could learn about the culture room, the Neuromuscular and Mitochondrial Pathology Laboratory, the freezer room and the High Technology Unit, which has a new confocal microscope equipped with the most advanced technological features and the first of this configuration that is installed throughout the State. Helena Ramal, coordinator of Laboratory Management, and Rosa Prieto, Head of the High Technology Unit, were the guides of these spaces.Finally, the visits to the VHIO began with a welcome given by Sergi Cuadrado, attached to the management. Subsequently, the citizens could discover how a biopsy is processed until they can be seen in the microscope thanks to the researchers José Jiménez, Roberta Fasani and Paola Martínez, from the VHIO Molecular Oncology Group. Then, the route was followed by the Laboratory of the Growth Factors Group and finally by the crop room. Here visitors were received and attended by Verónica Rodilla, Alex Martínez-Sabadell and Macarena Román, researchers from the same Group of Growth Factors, which was joined by Daniel Massó, scientific researcher of Peptomyc, a spin-off born from the VHIO.
