Recent Advances and Future Directions in Extracorporeal Carbon Dioxide Removal.

J Clin Med

December 2024

Department of Adult Critical Care, Guy's and St Thomas' NHS Foundation Trust, King's Health Partners, London SE1 9RT, UK.

Extracorporeal carbon dioxide removal (ECCOR) is an emerging technique designed to reduce carbon dioxide (CO) levels in venous blood while enabling lung-protective ventilation or alleviating the work of breathing. Unlike high-flow extracorporeal membrane oxygenation (ECMO), ECCOR operates at lower blood flows (0.4-1.

Background: In African populations, estimated glomerular filtration rate by cystatin C (eGFRcys) is better aligned with gold-standard GFR measurements than eGFR by creatinine (eGFRcr). Moreover, eGFRcys is unaffected by the effects of antiretroviral therapy (ART) on tubular secretion and may thus provide better estimates of GFR in people with HIV on ART.

Setting: Observational cohort study of people of African ancestry living with suppressed HIV RNA on ART in London, United Kingdom.

Human tumors are diverse in their natural history and response to treatment, which in part results from genetic and transcriptomic heterogeneity. In clinical practice, single-site needle biopsies are used to sample this diversity, but cancer biomarkers may be confounded by spatiogenomic heterogeneity within individual tumors. Here we investigate clonally expressed genes as a solution to the sampling bias problem by analyzing multiregion whole-exome and RNA sequencing data for 450 tumor regions from 184 patients with lung adenocarcinoma in the TRACERx study.

Neutrophil Extracellular Traps (NETs) as a Potential Target for Anti-Aging: Role of Therapeutic Apheresis.

Horm Metab Res

January 2025

Department of Intensive Care Medicine, Guy's and St Thomas' NHS Foundation Trust, London, United Kingdom of Great Britain and Northern Ireland.

Neutrophil extracellular traps (NETs) are large structures composed of chromatin, histones and granule-derived proteins released extracellularly by neutrophils. They are generally considered to be a part of the antimicrobial defense strategy, preventing the dissemination of pathogens. However, overproduction of NETs or their ineffective clearance can drive various pathologies, many of which are associated with advanced age and involve uncontrolled inflammation, oxidative, cardiovascular and neurodegenerative stress as underlying mechanisms.

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.

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.

Curr Opin Psychol

December 2024

Doctorate in Clinical Psychology, Department of Psychology, Royal Holloway, University of London, United Kingdom; Nuffield Department of Orthopaedics, Rheumatology, and Musculoskeletal Sciences (NDORMS), University of Oxford, United Kingdom.

Accumulating evidence suggests that stigma is a pervasive and pernicious psychosocial phenomenon that affects people living with chronic pain. In this narrative review, we describe the nature of stigma experienced by people with chronic pain and discuss its multifaceted determinants. These determinants include features of pain itself and intersectional factors, including comorbid conditions and social marginalization.

Uterotonics update.

Best Pract Res Clin Anaesthesiol

September 2024

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.
