Role of Preservation Solution in Human Aneurysmatic Aorta Harvest and Transport: A Comparative Analysis of Different Solutions for Tissue Injury Protection.

Introduction: Human aortic tissues in vitro are tools to clarify the pathophysiological mechanisms of the cardiovascular system, cell culture, and transplants. Therefore, this study aims to analyze and compare the preservation of human aneurysmatic aortic tissues in three different solutions.

Methods: Six human abdominal aortic aneurysms were obtained from patients after surgical ablation.

Challenges of Implementing a Human Multi-Tissue Bank in a Public Hospital in the Interior of São Paulo: Under the Light of the Quality Management System.

Background: Human multi-tissue banks (HMTB) are important health institutions specialized in the capture, processing, and distribution of human tissues for transplants and research, aiming for safety and quality in the supply of their products, intended for reconstructive surgeries and injury repair, in addition to contributing to the advancement of research developed in regenerative medicine. This study aims to report and share the experience of implementing an HMTB, as well as creating an institution's own quality management system.

Methods: This is a descriptive study, an experience report type, which identifies historical aspects of an HMTB's actions in the 5 years of implementing and operating the service.

Alpha 1-acid glycoprotein is upregulated in severe COVID-19 patients and decreases neutrophil NETs in SARS-CoV-2 infection.

Orosomucoid, or alpha-1 acid glycoprotein (AGP), is a major acute-phase protein expressed in response to systemic injury and inflammation. AGP has been described as an inhibitor of neutrophil migration on sepsis, particularly its immunomodulation effects. AGP's biological functions in coronavirus disease 2019 (COVID-19) are not understood.

Temperature Monitoring of Two Different Thermal Boxes for the Transport of Biological Samples.

Background: According to the Resolutions of the Collegiate Board of Directors RDC No. 20/2014, 214/2018, and 707/2022, validation of the temperature of thermal boxes for the transport of biological samples must be based on standardized procedures and tested by the Tissue Banks, guaranteeing safety and quality. Therefore, they can be simulated.

Educational Actions to Raise Student Awareness About the Donation and Transplantation of Human Organs and Tissues.

Background: In Brazil, family refusal to donate organs and tissues is the main reason for not performing transplants, making it necessary to implement different educational strategies in diverse populations on this topic. Thus, this study aimed to raise awareness among school-aged adolescents about the method of organ and tissue donation and transplantation.

Methods: This is a descriptive experience report with a quantitative and qualitative approach to educational actions in the school environment, mediated by the action research method, carried out with 936 students aged between 14 and 18 years from public schools in the interior of Sao Paulo, Brazil.

Isolation and primary culture of human abdominal aorta smooth muscle cells from brain-dead donors: an experimental model for vascular diseases.

Primary cell cultures are essential tools for elucidating the physiopathological mechanisms of the cardiovascular system. Therefore, a primary culture growth protocol of cardiovascular smooth muscle cells (VSMCs) obtained from human abdominal aortas was standardized. Ten abdominal aorta samples were obtained from patients diagnosed with brain death who were organ and tissue donors with family consent.

Models of Quality Management Systems Applied in Specialized Services for the Donation and Transplantation of Human Organs and Tissues.

Background: Quality management tools and models are used to improve processes and products, including those related to organ and tissue donation and transplantation protocols. This study aims to map, discuss, and disseminate models/tools of quality management systems applied in health services, specializing in the donation and/or transplantation of human organs and tissues.

Methods: This is an integrative literature review over the last 10 years, operationalized through searches carried out on the PubMed portal and the databases: SciVerse Scopus (SCOPUS), Scielo, Latin American and Caribbean Literature on Health Sciences (LILACS), Nursing Database (BDENF), and the Virtual Health Library (BVS).

The Significance of the Nucleic Acid Test (NAT) to Prevent Viral Contamination in Musculoskeletal Tissue Transplantation.

 The present study aims to highlight the significance of the nucleic acid test (NAT) for musculoskeletal tissue donation and to compare the sensitivity of this test on the different available platforms.  The present study is a retrospective survey in a human tissue bank database and an integrative literature review encompassing the last 10 years. The PubMed portal and the SCOPUS, CINAHL, and Web of Science databases were queried for articles.

Assessment of physicians' knowledge about brain death and organ donation and associated factors.

Precocity and assertiveness when diagnosing brain death are essential for identifying potential donors. To assess the knowledge of physicians about brain death and organ donation, cross-sectional web-based survey was carried out with physicians from different specialties. The knowledge about brain death and organ donation was assessed by a questionnaire with 12 multiple-choice or multiple-answer questions (possible range from 0 to 12).

MMP-2 and MMP-9 levels in plasma are altered and associated with mortality in COVID-19 patients.

Respiratory symptoms are one of COVID-19 manifestations, and the metalloproteinases (MMPs) have essential roles in the lung physiology. We sought to characterize the plasmatic levels of matrix metalloproteinase-2 and 9 (MMP-2 and MMP-9) in patients with severe COVID-19 and to investigate an association between plasma MMP-2 and MMP-9 levels and clinical outcomes and mortality. MMP-2 and MMP-9 levels in plasma from patients with COVID-19 treated in the ICU (COVID-19 group) and Control patients were measured with the zymography.

Implementation and certification of ISO 9001:2015 seal in human tissue bank HCFMRP-USP.

The Quality Management System has been a management technology applied to guarantee the quality of processes and products of a given organization. Thus, ISO 9001:2015 certification assists organizations that want to develop, implement, maintain, and improve a quality management system to enable process improvements and assessments to meet the needs of its customers. This experience report addresses the implementation and certification of the ISO 9001:2015 quality management seal at the Human Tissue Bank of the Ribeirão Preto Clinical Hospital (HCRP) at the University of São Paulo (USP) at Ribeirão Preto Medical School (FMRP)-Brazil.

Perspectives toward brain death diagnosis and management of the potential organ donor.

Background: Organ donation and transplantation represent one of the most important scientific advances over the last decades. Due to the complexity of these procedures and related ethical-legal aspects, however, there are a lot of doubts and uncertainty about the brain death diagnosis and the maintenance of potential organ donor.

Aim: To identify and discuss the different meanings and experiences of registered nurses and physicians from an adult intensive care unit in relation to the diagnosis of brain death and the maintenance of potential organ donors for transplantation purposes.
