Implementation Strategies Used to Reduce UEs in the Neonatal Intensive Care Unit.

Background: Unplanned extubation (UE) is the premature or unintended removal of an artificial airway and can cause worse patient outcomes. Study objectives were to describe implementation strategies used to reduce UE in the Hospital for Sick Children neonatal ICU (NICU) and their influence on UE rates, and contributing factors and patient characteristics of infants who had an UE, and compare them between the biological sexes. We hypothesized that the boys would experience more UEs and worse outcomes compared to the girls.

Anti-pig antibodies in swine veterinarian serum: Implications for clinical xenotransplantation.

Recent clinical xenotransplantation and human decedent studies demonstrate that clinical hyperacute rejection of genetically engineered porcine organs can be reliably avoided but that antibody mediated rejection (AMR) continues to limit graft survival. We previously identified porcine glycans and proteins which are immunogenic after cardiac xenotransplantation in non-human primates, but the clinical immune response to antigens present in glycan depleted triple knockout (TKO) donor pigs is poorly understood. In this study we use fluorescence barcoded human embryonic kidney cells (HEK) and HEK cell lines expressing porcine glycans (Gal and SDa) or proteins (tetraspanin-29 [CD9], membrane cofactor protein [CD46], protectin, membrane attack complex inhibition factor [CD59], endothelial cell protein C receptor, and Annexin A2) to screen antibody reactivity in human serum from 160 swine veterinarians, a serum source with potential occupational immune challenge from porcine tissues and pathogens.

Tracking in situ checkpoint inhibitor-bound target T cells in patients with checkpoint-induced colitis.

The success of checkpoint inhibitors (CPIs) for cancer has been tempered by immune-related adverse effects including colitis. CPI-induced colitis is hallmarked by expansion of resident mucosal IFNγ cytotoxic CD8 T cells, but how these arise is unclear. Here, we track CPI-bound T cells in intestinal tissue using multimodal single-cell and subcellular spatial transcriptomics (ST).

Racial Discrimination and Romantic Relationship Dynamics among Black Americans: A Systematic Review.

Despite increasing research, the links between racial discrimination and Black Americans' romantic relationship dynamics remain unclear. Guided by models of mundane extreme environmental stress (Peters & Massey, 1983), sociocultural family stress (McNeil Smith & Landor, 2018), and Black marital outcomes (Bryant et al., 2010), we conducted a systematic review of the literature examining racial discrimination and relationship dynamics among Black Americans in same-race and interracial romantic relationships.
