Abstract The disruption of mitochondrial homeostasis in neurons accounts for the onset and progression postoperative cognitive dysfunction (POCD). Echinacoside (ECH) can facilitate fusion to mediate neuroprotection, but its therapeutic efficacy is greatly limited by inefficient brain accumulation neuronal delivery. Herein, ECH‐encapsulated micelles are constructed from copolymer containing poly(carboxybetaine methacrylate) (PCBMA) block phenylboronic acid (PBA)‐modified poly(dimethylamino)ethyl methacrylate block, which mediates effective, brain‐targeted delivery via intranasal administration. In POCD mice, efficiently penetrate nasal mucosa betaine structure PCBMA that be recognized betaine‐GABA transporter 1 (BGT‐1) on epithelial cells, followed into hippocampus through submucosal olfactory trigeminal nerve pathways. Subsequently, internalized BGT‐1‐mediated endocytosis. over‐produced reactive oxygen species inside trigger dissociation ECH release, thereby inducing enhance neuron survival, ameliorate cerebral microenvironment, restore memory functions. This study reports a non‐invasive strategy overcome physiological barriers against drug renders profound implications treatment.

ABSTRACT Background The occurrence and development of postoperative cognitive dysfunction (POCD) are closely linked to neuroinflammation. This bibliometric analysis aims provide novel insights into the research trajectory, key topics, potential future trends in field neuroinflammation‐induced POCD. Methods Web Science Core Collection (WoSCC) database was searched identify publications from 2012 2023 on Bibliometric analysis, involving both statistical visual analyses, conducted using CiteSpace, VOSviewer, R software. Results Research POCD has exhibited an increasing trend over past 12 years. China had highest number publications, Nanjing Medical University most collaboration with other institutions, Zhiyi Zuo published author, Journal Neuroinflammation served as primary publication frequent keyword Keyword clustering indicated that predominant cluster is dexmedetomidine. Burst detection revealed delirium (POD), perioperative neurocognitive disorders (PND), apoptosis, epigenetic modifications were trends. Conclusions Our identified following areas associated POCD: anesthesia, surgery, dexmedetomidine, NLRP3 inflammasome, mechanism topics comprise POD, PND, modifications.

To explore the risk factors related to perioperative neurocognitive disorders (PND) in elderly patients with hip fractures, acute pain management as core. This study used a retrospective case-control method. 90 who underwent artificial femoral head replacement or total surgery our hospital from 2022 2023 were collected, and divided into PND group non-PND based on occurrence of PND. Collected data 17 conducted univariate multivariate regression analysis analyze contribution value fractures. Univariate showed that compared group, significant increase age, higher ASA class, longer surgical time, increased number nerve block cases, postoperative 12 h visual analogue scale (VAS) scores, 24 VAS levels CRP, PCT, BL-6 (P < 0.05). Multivariate found for BL-6. The protective class III II. undergoing fracture included scores (OR = 3.356), 2.311), CRP 1.058), PCT 18.661), 1.061). 0.039) II 0.016).

Abstract Intermittent fasting (IF) is an eating pattern that promotes health and cognitive improvement through periodic eating. It has been shown to enhance neuroplasticity reduce oxidative stress inflammation. Recent studies have demonstrated probiotic supplementation enhances performance by modulating gut microbiota composition increasing short‐chain fatty acid production, which in turn neurogenesis synaptic plasticity. The microbiota‐gut‐brain axis (MGBA) the communication bridge between brain, influencing function immune, endocrine, nervous systems. combination of probiotics IF may exert complementary effects on function, with enhancing microbial diversity metabolic efficiency, while further modulate barrier integrity neurotransmitter synthesis. This review critically examines interplay via MGBA, identifying key mechanisms potential therapeutic strategies remain underexplored current research.

Recent studies suggest a link between gut microbiota and neurological diseases, implicating the microbiome's role in health. However, specific alterations microbiome associated with migraine remain underexplored. This study aims to systematically review existing literature determine whether patients are changes composition. A systematic was conducted accordance PRISMA statement. We included original empirical investigating patients. Data extracted design, participant demographics, differences at various taxonomic levels, measures of microbial diversity (alpha beta diversity). The search selection process involved four independent reviewers who assessed abstracts full texts ensure eligibility. evaluated using relative abundance indices. Six studies, encompassing regions including China, Korea, Italy, were analysis. results indicated significant controls. Key findings include reduction Faecalibacterium, genus known for its anti-inflammatory properties, patients, those chronic migraine. Conversely, Veillonella exhibited elevated compared Other taxa, such as Prevotella Parabacteroides, showed variable associations across different suggesting dysbiotic environment highlights that migraines microbiota, decreased key taxa. These dysbiosis may play pathophysiology. Further research is needed explore potential causal relationships therapeutic implications, particularly targeting management.
