Peripheral oxygen saturation levels as a guide to avoid hyperoxia: an observational study.
Scand J Trauma Resusc Emerg Med
January 2025
Department of Acute Care, University Medical Centre Groningen, Groningen, the Netherlands.
Background: As iatrogenic hyperoxia has been related to adverse outcomes in critically ill patients, guidelines advise to titrate oxygen to physiological levels. In the prehospital setting where partial arterial oxygen (PaO) values are often not readily available, titration of oxygen is based on peripheral oxygen saturations (SpO2). In this study we aimed to investigate the efficacy of SpO guided oxygen titration in the prevention of hyperoxia.

A potential near-term clinical application is to calculate polygenic risk score (PRS) to improve disease risk prediction. The value of PRS, as part of numerous multi-source variables used to define asthma, remains unclear.

Background: Sucrose non-fermenting-1-related protein kinases (SnRKs) have been implicated in plant growth and stress responses. Although SnRK3.23 is known to be involved in drought stress, the underlying mechanism of resistance differs between Arabidopsis and rice, and little is known about its function in wheat.

Department of Plastic and Reconstructive Surgery, Addenbrookes Hospital, Hills Rd, Cambridge, CB2 0QQ, UK.
Purpose: Management of the elderly patients presenting with open lower limb fractures is challenging due to physiological changes and pre-existing co-morbidities. The aim of this study was to assess the compliance with the British Orthopaedic Association's Standards for Trauma Number 4 (BOAST 4) guidelines in this patient group.
Methods: The study included a retrospective analysis of all the patients aged > 65 years old admitted with open lower limb fracture between 2017 and 2019 to a major trauma centre (MTC) in East of England.
Eight weeks of aerobic exercise, but not four, improves insulin sensitivity and cardiovascular performance in young women.
Sci Rep
January 2025
Biomedical Research Center, Qatar University, P.O Box 2713, Doha, Qatar.
Regular aerobic exercise has a significant impact on glucose metabolism and lipid profiles, contributing to overall health improvement. However, evidence for optimal exercise duration to achieve these effects is limited. This study aims to explore the effects of 4 and 8 weeks of moderate-intensity aerobic exercise on glucose metabolism, lipid profiles, and associated metabolic changes in young female students with insulin resistance and varying body mass, seeking to determine the optimal duration for physiological adaptations.
