Measuring the impact of cardiotocograph decision support software on neonatal outcomes: A propensity score-matched observational study.

Aust N Z J Obstet Gynaecol 2021 May 13. Epub 2021 May 13.

Mater Mothers' Hospital, South Brisbane, Queensland, Australia.

Background: This study follows the 2017 UK INFANT Collaborative Group RCT, which compared neonatal outcomes with and without the use of the INFANT cardiotocograph decision support system for over 46 000 patients in labour. The original trial failed to demonstrate a significant improvement to neonatal outcomes; however, the study design was subject to methodological critique.

Aims: This Australian retrospective cohort study aimed to report perinatal outcomes before and after the introduction of INFANT decision support software for cardiotocograph use in labour. Read More

Targeted temperature management at 33 degrees Celsius in patients with high-grade aneurysmal subarachnoid hemorrhage: a protocol for a multicenter randomized controlled study.

Ann Transl Med 2021 Apr;9(7):581

Department of Neurosurgery, Xuanwu Hospital, Capital Medical University, Beijing, China.

Background: Studies on the use of therapeutic hypothermia (TH) to improve the outcome of high-grade aneurysmal subarachnoid hemorrhage (aSAH), show promising, though conflicting results because of the lack of high-quality trials. The aim of this study is to evaluate the safety and efficacy of TH (maintaining bladder temperature at 33 °C for ≥72 h) to treat patients with high-grade aSAH (Hunt-Hess grade IV-V).

Methods: A multicenter, randomized, controlled clinical trial will be conducted for October 2020 to September 2024 involving 10 clinics. Read More

Brain and Myocardial Mitochondria Follow Different Patterns of Dysfunction After Cardiac Arrest.

Shock 2021 May 11. Epub 2021 May 11.

Univ Paris Est Créteil, INSERM, IMRB, F-94010 Créteil, France Ecole nationale vétérinaire d'Alfort, IMRB, F-94700 Maisons-Alfort, France.

Abstract: Mitochondria is often considered as the common nexus of cardiac and cerebral dysfunction after cardiac arrest. Here, our goal was to determine whether the time course of cardiac and cerebral mitochondrial dysfunction is similar after shockable vs nonshockable cardiac arrest in rabbits. Anesthetized rabbits were submitted to 10 min of no-flow by ventricular fibrillation (VF group) or asphyxia (non-shockable group). Read More

Posterior subthalamic nucleus (PSTh) mediates innate fear-associated hypothermia in mice.

Nat Commun 2021 May 11;12(1):2648. Epub 2021 May 11.

National Institute of Biological Sciences (NIBS), Beijing, China.

The neural mechanisms of fear-associated thermoregulation remain unclear. Innate fear odor 2-methyl-2-thiazoline (2MT) elicits rapid hypothermia and elevated tail temperature, indicative of vasodilation-induced heat dissipation, in wild-type mice, but not in mice lacking Trpa1-the chemosensor for 2MT. Here we report that Trpa1 mice show diminished 2MT-evoked c-fos expression in the posterior subthalamic nucleus (PSTh), external lateral parabrachial subnucleus (PBel) and nucleus of the solitary tract (NTS).

Mild hypothermia facilitates mitochondrial transfer from astrocytes to injured neurons during oxygen-glucose deprivation/reoxygenation.

Neurosci Lett 2021 May 7:135940. Epub 2021 May 7.

Department of Anesthesiology, Second Hospital of Hebei Medical University, Shijiazhuang, 050000, Hebei, China. Electronic address:

Mitochondrial dysfunction is now considered an important sign of neuronal death during cerebral ischemia/reperfusion (I/R) injury. Studies have shown that the transfer of mitochondria from astrocytes to injured neurons contributes to endogenous neuroprotection after stroke. Basic and clinical studies have shown that mild hypothermia exerts a clear protective effect on neurons after cerebral ischemic injury, but the role of mild hypothermia in this endogenous neuroprotective mechanism remains unclear.

Adv Exp Med Biol 2021 ;1269:31-38

Department of Medical Physics and Biomedical Engineering, University College London, London, UK.

Hypoxic ischaemic encephalopathy (HIE) is a significant cause of death and disability. Therapeutic hypothermia (TH) is the only available standard of treatment, but 45-55% of cases still result in death or neurodevelopmental disability following TH. This work has focussed on developing a new brain tissue physiology and biochemistry systems biology model that includes temperature effects, as well as a Bayesian framework for analysis of model parameter estimation.

High rate of critical coronary stenosis in comatose patients with Non-ST-elevation out-of-hospital cardiac arrest (NSTE-OHCA) undergoing therapeutic hypothermia-Experience from the HAnnover COoling REgistry (HACORE).

PLoS One 2021 4;16(5):e0251178. Epub 2021 May 4.

Department of Cardiology and Angiology, Medizinische Hochschule Hannover, Hannover, Germany.
