Expression of lncRNAs NEAT1, PACERR, and GAS5 can be associated with disease activity in rheumatoid arthritis patients.
Long noncoding RNAs (lncRNAs) have long been considered molecular noise within the transcriptome, but over time it has been shown that they perform many important biological functions and are associated with various inflammatory and autoimmune diseases, including rheumatoid arthritis (RA). ⋯ Circulating plasma lncRNAs may be considered as supporting molecular markers associated with RA activity and may be useful in identifying the disease exacerbation.

In the PROTECTION trial, intravenous amino acids (AA) decreased the occurrence of acute kidney injury (AKI) in cardiac surgery patients with cardiopulmonary bypass (CPB). Recruitment of renal functional reserve may be responsible for such protection. However, patients with chronic kidney disease (CKD) have diminished renal functional reserve, and AA may be less protective in such patients. Thus, a separate investigation of such patients is warranted. ⋯ AA infusion protected CKD patients undergoing CPB from developing AKI, with an absolute risk reduction of 7% and a NNT of 14 in a cohort with a >45% rate of AKI. Moreover, it delivered a >50% relative risk reduction in severe AKI.

ReviewNovel factors affecting fibrin clot formation and their clinical implications.
Fibrin formation is pivotal in hemostasis, serving as a temporary barrier to blood loss following vascular injury, while in thrombosis this process is involved in thrombus progression, stability, and recurrence. Growing evidence shows exceptional complexity of processes that determine fibrin clot structure and function, especially lysability, both in health and disease, which might be relevant in the pathogenesis of arterial and venous thromboembolic diseases. ⋯ These factors have been shown to be not only associated with ischemic stroke, myocardial infarction, pulmonary embolism, and cardiovascular death, but also with unfavorably altered fibrin clot characteristics, which underscores clinical relevance of fibrin clot properties. Given preclinical or ongoing studies aimed at modifying some of these factors, in particular FXI/FXIa inhibitors, recent findings might expand our knowledge on fibrin‑related mechanisms of emerging therapeutic agents tested and stimulate further research into new targets for future therapeutic interventions to prevent thromboembolic events.

Delirium is an organic mental syndrome significantly associated with long-term cognitive decline, increased hospital stays and higher mortality. This systematic review of randomised controlled trials (RCTs) with meta-analysis assesses the association of remimazolam with postoperative cognitive function and delirium compared with non-benzodiazepine hypnotics. ⋯ PROSPERO CRD42024532751.

Military and commercial stakeholders are investing to explore the use of hypersonic aircraft and orbital spacecraft to transport cargo, medical supplies, passengers, and casualties. These vehicle platforms require periods of sustained acceleration, but to date, these dynamic forces have not been comprehensively considered in the environment of critical care patient movement because injured patients and advanced aeromedical evacuation (AE) equipment are rarely subjected to these conditions. While military AE equipment does undergo crash hazard acceleration testing, equipment functionality during or after sustained acceleration remains to be evaluated. This study was performed to fill that knowledge gap. ⋯ The EMV+ 731 ventilator and Propaq MD cardiac monitor had reliable clinical performance despite sustained acceleration. This knowledge will facilitate immediate follow-on experimentation with advanced models of combat injury during simulated medical evacuation in sustained acceleration environments.
