Objective Understand the experiences and expectations of intensive care unit nurses in caring for organ donors and their families. Method Qualitative research, with a social phenomenological approach, conducted in 2013 with 20 nurses. Results The experiences of the nurses with the families of donors were represented by two categories: obstacles encountered and interventions performed in the care of the donors' families. The expectations of these professionals in caring for organ donors and their families were described in the category: care to save lives. Conclusion The study showed that the day-to-day work of intensive care nurses in their care of organ donors and their families is permeated with obstacles that interfere in the donation process. In light of this, their goal is to provide intensive care to deceased donors and humanized care to the families, to help family members agree to organ donation and enable organs to be made available for transplants.

Chronic diabetic wounds present significant treatment challenges due to their complex microenvironment, often leading to suboptimal healing outcomes. Hydrogen sulfide (HS), a crucial gaseous signaling molecule, has shown great potential in modulating inflammation, oxidative stress and extracellular matrix remodeling, which are essential for effective wound healing. However, conventional HS delivery systems lack the adaptability required to meet the dynamic demands of different healing stages, thereby limiting their therapeutic efficacy.

Background: Controlled donation after circulatory determination of death (DCD) is feasible only if circulatory arrest occurs soon after withdrawal of life-sustaining measures (WLSM). When organ recovery cannot proceed because this time interval is too long, there are potential negative implications, including perceptions of "secondary loss" for patients' families and significant resource consumption. The DCD-N score is a validated clinical tool for predicting rapid death following WLSM.

Background: Improvement in gene modifications of donor pigs has led to the prevention of early cardiac xenograft rejection and significantly prolonged cardiac xenograft survival in both heterotopic and orthotopic preclinical non-human primate (NHP) models. This progress formed the basis for FDA approval for compassionate use transplants in two patients.
Methods: Based on our earlier report of 9-month survival of seven gene-edited (7-GE) hearts transplanted (life-supporting orthotopic) in baboons, we transplanted 10 gene-edited pig hearts into baboons (n = 4) using non-ischemic continuous perfusion preservation (NICP) and immunosuppression regimen based on co-stimulation blockade by anti-CD40 monoclonal antibody.
Background: Increasing syphilis infection rates are a concerning issue worldwide. Blood donation screening is an opportunity to monitor the burden of asymptomatic infections, providing information on contemporary factors associated with infection and public health insights into transmission.
Methods: Blood donations collected at five Brazilian blood centers between January 2020 and February 2022 were screened with treponemal or non-treponemal assays according to local protocols, followed by alternate Enzyme-Linked Immunosorbent Assay (ELISA); samples with reactive or indeterminate results in the alternate ELISA were further tested with the rapid plasma reagin (RPR), and categorized as RPR-positive or RPR-negative.

In asthma, tissue factor (TF) levels are elevated in the lung. In our previous studies using mechanically compressed human bronchial epithelial (HBE) cells, which are a well-defined in vitro model of bronchoconstriction during asthma exacerbations, we detected TF within extracellular vesicles (EVs) released from compressed HBE cells. Here, to better characterize the potential role of this mechanism in asthma, we tested the extent to which the transcriptional regulation of epithelial cell-derived TF varied between donors with and without asthma.
