Introduction And Objectives: High flow nasal cannula (HFNC) therapy is an increasingly popular mode of non-invasive respiratory support for the treatment of patients with acute hypoxemic respiratory failure (AHRF). Previous experimental studies in healthy subjects have established that HFNC generates flow-dependent positive airway pressures, but no data is available on the levels of mean airway pressure (mP) or positive end-expiratory pressure (PEEP) generated by HFNC therapy in AHRF patients. We aimed to estimate the airway pressures generated by HFNC at different flow rates in patients with AHRF, whose functional lung volume may be significantly reduced compared to healthy subjects due to alveolar consolidation and/or collapse.

Inequalities in cancer two-week-wait referrals: a cross-sectional study in English general practice.

BJGP Open

January 2025

School of Life Course and Population Sciences, Faculty of Life Sciences and Medicine, King's College London, London, United Kingdom.

Background: Practices with higher two-week-wait (2WW) referral-rates demonstrate higher survival for several cancers. Yet, there is little up-to-date evidence exploring factors influencing 2WW-referral-rates and whether health inequalities exist, particularly after COVID-19.

Aim: To establish which patient-factors (eg, age, sex, ethnicity, deprivation) and practice-factors (eg, remote consultations, frequency of seeing a preferred-GP) independently predict 2WW-referral-rates.

Maximum Tumor Diameter is Associated with Relapse Risk in Limited-Stage Hodgkin Lymphoma: An International Study.

Blood Adv

January 2025

Division of Cancer Sciences, University of Manchester, Manchester Academic Health Science Centre, and Department of Medical Oncology, The Christie Hospital, Manchester, United Kingdom.

Tumour bulk is an established prognostic factor in Hodgkin lymphoma (HL) but most patients with limited-stage (LS) HL do not have 'bulk' by standard binary definitions. In the RAPID trial, maximum tumor diameter (MTD) was associated with risk of relapse for LS-HL patients achieving PET-negativity after ABVD chemotherapy. We aimed to externally validate these findings in the H10 trial.

Center for Reproductive Medicine, Department of Anesthesiology, Perioperative and Pain Medicine, Brigham and Women's Hospital, Boston, MA, USA; Harvard Medical School, USA. Electronic address:

Uterotonics are the mainstay of management for postpartum haemorrhage and an understanding of their use is essential for the obstetric anaesthetist. First-line uterotonics comprise oxytocin and carbetocin, which act on the oxytocin receptor, and recent research has shown that lower doses of first-line uterotonics can be used to adequate effect. The oxytocin receptor is known to undergo desensitisation with exposure to the agonist over time and with increasing concentrations.

The mutually antagonistic relationship of atypical protein kinase C (aPKC) and partitioning-defective protein 6 (Par6) with the substrate lethal (2) giant larvae (Lgl) is essential for regulating polarity across many cell types. Although aPKC-Par6 phosphorylates Lgl at three serine sites to exclude it from the apical domain, aPKC-Par6 and Lgl paradoxically form a stable kinase-substrate complex, with conflicting roles proposed for Par6. We report the structure of human aPKCι-Par6α bound to full-length Llgl1, captured through an aPKCι docking site and a Par6 contact.

Motor-sparing regional anaesthesia for total knee arthroplasty: a narrative and systematic literature review.

Br J Anaesth

January 2025

Department of Theatres, Anaesthesia and Perioperative Medicine, Guy's and St Thomas' NHS Foundation Trust, London, UK; Faculty of Life Sciences and Medicine, King's College London, London, UK.

Total knee arthroplasty is a life-changing surgical procedure that is associated with a high incidence of severe postoperative pain. Key to enhancing recovery after surgery is effective analgesia and early mobilisation. Innovations in motor-sparing regional anaesthesia techniques that have improved recovery include targeted surgical local infiltration analgesia, adductor canal blockade, genicular nerve blocks, and the infiltration between the popliteal artery and posterior capsule of the knee (iPACK) block.

Neurons in the central nervous system (CNS) lose regenerative potential with maturity, leading to minimal corticospinal tract (CST) axon regrowth after spinal cord injury (SCI). In young rodents, knockdown of PTEN, which antagonises PI3K signalling by hydrolysing PIP3, promotes axon regeneration following SCI. However, this effect diminishes in adults, potentially due to lower PI3K activation leading to reduced PIP3.
