Oxygenation during the apnoeic phase preceding intubation in adults in prehospital, emergency department, intensive care and operating theatre environments.

Background: Apnoeic oxygenation is the delivery of oxygen during the apnoeic phase preceding intubation. It is used to prevent respiratory complications of endotracheal intubation that have the potential to lead to significant adverse events including dysrhythmia, haemodynamic decompensation, hypoxic brain injury and death. Oxygen delivered by nasal cannulae during the apnoeic phase of intubation (apnoeic oxygenation) may serve as a non-invasive adjunct to endotracheal intubation to decrease the incidence of hypoxaemia, morbidity and mortality.

Brain PET and SPECT imaging and quantification: a survey of the current status in the UK.

Objectives: With disease-modifying therapies in development for neurological disorders, quantitative brain imaging techniques become increasingly relevant for objective early diagnosis and assessment of response to treatment. The aim of this study was to evaluate the use of Brain SPECT and PET scans in the UK and explore drivers and barriers to using quantitative analysis through an online survey.

Methods: A web-based survey with 27 questions was used to capture a snapshot of brain imaging in the UK.

Post-Transcriptional Regulation of PARP7 Protein Stability Is Controlled by Androgen Signaling.

Poly-ADP-ribose polymerases (PARPs) are enzymes that catalyze ADP-ribosylation and play critical roles in normal and disease settings. The PARP family member, PARP7, is a mono-ADP-ribosyltransferase that has been suggested to play a tumor suppressive role in breast, ovarian, and colorectal cancer. Here, we have investigated how androgen signaling regulates PARP7 homeostasis in prostate cancer cells, where is a direct target gene of AR.

Comparison of Supraglottic Airway Devices With Endotracheal Intubation in Low-Risk Patients for Cesarean Delivery: Systematic Review and Meta-analysis.

Background: The safety and adverse event rate of supraglottic airway (SGA) devices for cesarean delivery (CD) is poorly characterized. The primary aims of this review were to determine whether the first-pass success was higher and time to insertion for SGA was faster than endotracheal intubation for elective CD. The secondary aim was to determine the airway-related adverse event rate associated with SGA use compared to endotracheal intubation in elective CD under general anesthesia (GA).
