Stabilisation and resuscitation with intact cord circulation is feasible using a wide variety of approaches; a scoping review.

Aim: This scoping review identified studies on approaches to intact cord resuscitation and/or stabilisation (ICR/S) for neonates delivered by Caesarean section (C-section).

Methods: A systematic literature search was carried out using the PubMed, Web of Science, Scopus, Cochrane and CINAHL databases to identify papers published in English from inception to 14 November 2022.

Results: We assessed 2613 studies and included 18 from 10 countries, covering 1-125 C-sections: the United States, the United Kingdom, Australia, India, Italy, China, France, The Netherlands, New Zealand and Taiwan.

Human saliva, plasma and breast milk exosomes contain RNA: uptake by macrophages.

Background: Exosomes are 30-100 nm membrane vesicles of endocytic origin produced by numerous cells. They can mediate diverse biological functions, including antigen presentation. Exosomes have recently been shown to contain functional RNA, which can be delivered to other cells.
