A Scoping Review of Comparative Healthcare Codes of Ethics Studies.

Background: Codes of ethics are, for many, important documents that define the key values and behaviours expected of healthcare professionals. They are also documents that have been widely criticised. These criticisms range from being vague to failing to provide guidance on many important issues.

An immunoregulatory amphipathic peptide derived from Fasciola hepatica helminth defense molecule (FhHDM-1.C2) exhibits potent biotherapeutic activity in a murine model of multiple sclerosis.

The helminth defense molecules (HDM) are a family of immune regulatory peptides exclusively expressed by trematode worms. We have previously demonstrated that in vivo FhHDM-1, the archetypal member of the HDMs, regulated macrophage responses to inflammatory ligands, thereby ameliorating the progression of immune-mediated tissue damage in several murine models of inflammatory disease. Accordingly, we postulated that an understanding of the structure-function relationship of the HDMs would facilitate the identification of the minimal bioactive peptide, which would represent a more synthesizable, cost-effective, potent biotherapeutic.

Predicting operative mortality in patients who undergo elective open thoracoabdominal aortic aneurysm repair.

Background: We have developed a model aimed at identifying preoperative predictors of operative mortality in patients who undergo elective, open thoracoabdominal aortic aneurysm (TAAA) repair. We converted this model into an intuitive nomogram to aid preoperative counseling.

Methods: We retrospectively analyzed data from 2884 elective, open TAAA repairs performed between 1986 and 2023 in a single practice.

Mesenchymal stromal cells reduce inflammation and improve lung function in a mouse model of cystic fibrosis lung disease.

Mesenchymal stromal cells (MSCs) are multipotent adult stem cells which possess immunomodulatory and repair capabilities. In this study, we investigated whether MSC therapy could modulate inflammation and lung damage in the lungs of Scnn1b-transgenic mice overexpressing the β-subunit of the epithelial sodium channel (β-ENaC), a model with features of Cystic Fibrosis lung disease. Human bone marrow derived MSC cells were intravenously delivered to mice, prior to collection of bronchoalveolar lavage (BALF) and tissue.

PROTECTION OF MICE AGAINST CECAL LIGATION AND PUNCTURE-INDUCED POLYMICROBIAL SEPSIS BY A FASCIOLA HEPATICA HELMINTH DEFENSE MOLECULE.

Sepsis results from a dysregulated host immune response to infection and is responsible for ~11 million deaths each year. In the laboratory, many aspects of sepsis can be replicated using a cecal ligation and puncture model, which is considered the most clinically relevant rodent model of sepsis. In the present study, histological and biomarker multiplex analyses revealed that the cecal ligation and puncture model initiated a large-scale inflammatory response in mice by 24 h, with evidence of acute organ damage by 48-72 h.
