Objective: To examine the inter-rater reliability of The King's Outcome Scale for Childhood Head Injury (KOSCHI) with clinicians of varying experience in paediatric traumatic brain injury (TBI); and to examine change in outcome during long-term follow-up of children following traumatic brain injury (TBI) using KOSCHI.

Method: Retrospective assessment of detailed clinic reports of 97 children followed-up by a tertiary specialist paediatric brain injury service. Investigators were blinded to each other's scores.

Results: Inter-rater reliability was substantial (weighted kappa 0.71) and similar for investigators of varying experience. KOSCHI outcome was strongly associated with markers of injury severity (p = 0.028). In longitudinal follow-up, KOSCHI score worsened in 7 (23%) children who were injured under 8 years but in no older children (p = 0.02).

Conclusion: KOSCHI has high inter-rater reliability for investigators of different experience. Long-term KOSCHI outcome is associated with injury severity. Some young children may develop worse disability over time.

Background: Direct carotid-cavernous fistulas (CCFs) are relatively rare but dangerous complications of penetrating traumatic brain injury or maxillofacial trauma. A variety of clinical signs have been described, including ophthalmological and neurological ones. In some cases, severely altered cerebral blood flow can present as massive life-threatening bleeding through the nose, subarachnoid hemorrhage, and/or intraparenchymal hemorrhage.

Introduction: Self-harm represents a complex and multifaceted public health issue of global significance, exerting profound effects on individuals and communities alike. It involves intentional self-poisoning or self-injury with or without the motivation to die. Although self-harm is highly prevalent, limited research has focused on the patterns and trends of self-harm among hospital populations in low- and middle-income countries, particularly within Africa.

Aim: To explore the trajectories of consciousness recovery and prognosis-associated predictors in children with prolonged disorder of consciousness (pDoC).

Method: This single-centre, retrospective, observational cohort involved 134 (87 males, 47 females) children diagnosed with pDoC and hospitalized at the Department of Rehabilitation at the Children's Hospital of Chongqing Medical University in China. The median onset age was 30 (interquartile range [IQR] 18-54) months, with onset ages ranging from 3 to 164 months.

Concussions are a common form of mild traumatic brain injury characterized by a transient alteration of cerebral function leading to a range of physical, cognitive, and emotional symptoms. Postconcussive symptoms (PCSs) usually resolve in about a week but can persist in 10% to 15% of patients. If left untreated, PCS can profoundly affect a patient's life.

Liposomes-Loaded miR-9-5p Alleviated Hypoxia-Ischemia-Induced Mitochondrial Oxidative Stress by Targeting ZBTB20 to Inhibiting Nrf2/Keap1 Interaction in Neonatal Mice.

Hypoxia ischemia (HI) is a leading cause of cerebral palsy and long-term neurological sequelae in infants. Given that mitochondrial dysfunction in neurons contributes to HI brain damage, this study aimed to investigate the regulatory role of miR-9-5p in mitochondrial function following HI injury. Overexpression of miR-9-5p in HI mice or HO-exposed PC12 cells suppressed neuronal injury, associated with increased mitochondrial copy number, normalizing mitochondrial membrane potential, improved nuclear factor-erythroid factor 2-related factor 2 (Nrf2) activation, and downregulation of Keap1.
