Assessment of haemostatic function in paediatric surgical patients: 'if you prick us, do we not bleed?'.
Healthy babies have ∼50% of adult procoagulant factor levels, but without an increased risk of bruising or bleeding. The preoperative clotting tests, prothrombin time and partial thromboplastin time, are frequently performed in infants and children. However, the clinical usefulness of screening coagulation tests remains controversial. ⋯ Enhanced coagulability was previously demonstrated on some viscoelastic testing devices using blood from younger infants. This editorial focuses on several key findings from the paediatric reference range study using a new whole blood viscoelastic coagulation test system, ClotPro® (Haemonetics, Boston, MA, USA). Altered clotting patterns in younger infants, underlying mechanisms of coagulation, and potential clinical implications are discussed.

Blocking increased expression of nerve injury-specific long non-coding RNA (NIS-lncRNA) in injured dorsal root ganglia (DRG) through DRG microinjection of NIS-lncRNA small hairpin interfering RNA or generation of NIS-lncRNA knockdown mice mitigates neuropathic pain. However, these strategies are impractical in the clinic. This study employed a Food and Drug Administration (FDA)-approved antisense oligonucleotides strategy to examine the effect of NIS-lncRNA ASOs on neuropathic pain. ⋯ These findings further validate the role of NIS-lncRNA in trauma-, chemotherapy-, or diabetes-induced neuropathic pain and demonstrate potential clinical application of NIS-lncRNA antisense oligonucleotides for neuropathic pain management.

Dexmedetomidine is a widely used anaesthetic adjuvant for cancer resection surgeries. However, recent reports suggest that it may promote tumour growth or metastasis, so it is essential to clarify its tumour-related effects. ⋯ Dexmedetomidine conferred colorectal tumour-type specific suppression by modulation of tumour CD4+ and CD8+ T cells without tumour-enhancing effects.
