Vacuum assisted and gravitational venous drainage in aortic valve surgery: A propensity-match study.

Introduction: Vacuum assisted venous drainage (VAVD) is widely adopted in minimally invasive cardiac surgery. VAVD enables the advantage of using smaller cannulae in a reduced surgical field while allowing satisfactory drainage and pump flow. The production of gaseous micro-emboli is a recognized risk associated with VAVD, however no difference in clinical endpoints have been reported between patients operated on with gravity venous drainage (GVD) or with VAVD.

'From the sky to the ground': fishers' knowledge, landscape analysis and hydrological data indicate long-term environmental changes in Amazonian clear water rivers.

Fishers possess detailed local ecological knowledge (LEK) which can be a valuable resource for tracking long-term environmental changes in less studied tropical rivers. Our goal was to investigate such changes in three clear water rivers in the Brazilian Amazon, focusing on hydrology, water quality and land cover. Additionally, we aimed to compare these changes among three rivers (Trombetas, Tapajós and Tocantins) representing a potential gradient of environmental changes.

del Nido and Histidine-Tryptophan-Ketoglutarate cardioplegia in minimally invasive mitral valve surgery: A propensity-Match study.

Introduction: In the last decade, del Nido cardioplegia has been embedded in adult cardiac surgery involving CABG and aortic valve surgical procedures. We reviewed our early experience with del Nido cardioplegia in the setting of minimally invasive mitral valve surgery.

Methods: Data on 120 consecutive patients operated between 03/2021 and 06/2022 were retrieved from our internal database (infective endocarditis and urgent operations were excluded).

Fishers' multidimensional knowledge advances fisheries and aquatic science.

Fishers' Indigenous and local knowledge (ILK) has multidimensional contributions to improve fisheries and aquatic ecosystems science, ranging from algae to whales and including management, conservation, ecology, and impact assessment. The challenges are to sustain this knowledge, recognize its value, and to include ILK holders in resource management and decision-making.

Coronary unroofing does not fits all anomalous aortic origin of coronary arteries.

Introduction: Anomalous aortic origin of coronary artery (AAOCA) is the second leading cause of sudden cardiac death in children and young adults. Intramural-interarterial course is the most frequent anatomic variation and coronary unroofing is widest adopted for surgical management. Symptoms recurrence is described regardless of the technique used.
