A Prospective Management Strategy for Heterotaxy Syndrome with Intestinal Rotation Abnormalities: Imaging Does Not Predict Need for Surgery.

Purpose: Heterotaxy syndrome (HS) affects right-left anatomical development in 3% of children with congenital heart disease. Commonly, these patients have intestinal rotation abnormalities (IRA) that differ from typical malrotation. In this prospective study, we examine the development of a management pathway, imaging findings, and clinical course of patients with HS and IRA.

Injectable oxygenation therapeutics: evaluating the oxygen delivery efficacy of artificial oxygen carriers and kosmotropes .

The aim of this paper was to utilise an existing setup to quantify the oxygen offloading capabilities of two different subsets of injectable oxygenation therapeutics: (1) artificial oxygen carriers (AOCs), which bind or dissolve oxygen and act as transport vectors, and (2) kosmotropes, which increase water hydrogen bonding and thereby decrease the resistance to oxygen movement caused by the blood plasma. Dodecafluoropentane emulsion (DDFPe) was chosen to represent the AOC subset while trans sodium crocetinate (TSC) was selected to represent the kosmotrope subset. PEG-Telomer-B (PTB), the surfactant utilised to encapsulate DDFP in emulsion form, was also tested to determine whether it affected the oxygen transport ability of DDFPe.

In vitro model to compare the oxygen offloading behaviour of dodecafluoropentane emulsion (DDFPe).

The aim of this paper was to create an in vitro setup to quantify the oxygen offloading capabilities of dodecafluoropentane emulsion (DDFPe) in a hypoxic environment. Oxygen offloading from DDFPe was characterized under different gaseous environments and under pre-oxygenated conditions. Results of this study showed that (1) oxygen offloading is inversely related to the solubility of the selected sparging gas in saline and (2) both pre-oxygenated and simultaneously oxygenated DDFPe display similar magnitudes of oxygen transport.
