Comanagement of surgical patients between neurosurgeons and internal-medicine clinicians: observational cohort study

The rising prevalence of chronic diseases have contributed to a population with high complexity of care. There has been an increasing need for a new organizational model based on the interaction in the same department between the specialist skills of surgical and medical disciplines. This study aims to describe the implementation of a hospitalist co-management program in a Neurosurgery Department (ND) and its impact on the incidence of medical complications, 30 days readmission rate for medical causes, number of transfers to Intensive Care Units (ICU)/Neurosurgical Intensive Care Unit (NICU) or to medical wards (MW), length-of stay (LOS), mortality and satisfaction of health workers. We conducted an observational study comparing changes before and after the Internal medicine-Neurosurgical Comanagement (INC) intervention. We conducted a retrospective evaluation of patients enrolled before the INC intervention and a prospective evaluation of those enrolled after the INC intervention was implemented. We defined the pre-INC intervention group as 380 patients admitted to the ND for neurosurgical disease between January 2022 and April 2022 and the post-INC intervention group as 367 patients admitted to the ND between January 2023 and April 2023. INC intervention was associated with a significant decrease in medical complications during the hospital stay (OR 0.52; 95% CI; 0.39-0.70, p < 0.001), 30 days in-hospital readmission for medical reasons (OR 0.95; 95% CI 0.93-0.97, p < 0.001) and numbers of transfers to ICU/NICU (OR 0.31; 95% CI; 0.17-0.55, p < 0.001) or MW (OR 0.51; 95% CI 0.33-0.77, p = 0.002). During the INC intervention period, we observed a high satisfaction rate in health workers, evaluated by standardized questionnaire. In our study, LOS, in-hospital mortality and 30-day mortality were not significantly associated with INC. Hospitalist co-management in Neurosurgical Departments was associated with a reduced incidence of medical complications, 30-days in-hospital readmission and numbers of transfers to ICU/NICU or MW with a high satisfaction rate among healthcare workers, but without a significant decrease in LOS and mortality rate.

FYN and CD247: key Genes for Septic Shock Based on Bioinformatics and Meta-Analysis

BACKGROUND

Septic shock is sepsis accompanied by hemodynamic instability and high clinical mortality.

MATERIAL AND METHODS

GSE95233, GSE57065, GSE131761 gene-expression profiles of healthy control subjects and septic shock patients were downloaded from the Gene-Expression Omnibus (GEO) database, and differences of expression profiles and their intersection were analysed using GEO2R. Function and pathway enrichment analysis was performed on common differentially expressed genes (DEG), and key genes for septic shock were screened using a protein-protein interaction network created with STRING. Also, data from the GEO database were used for survival analysis for key genes, and a meta-analysis was used to explore expression trends of core genes. Finally, high-throughput sequencing using the blood of a murine sepsis model was performed to analyse the expression of CD247 and FYN in mice.

RESULTS

A total of 539 DEGs were obtained (p < 0.05). Gene ontology analysis showed that key genes were enriched in functions, such as immune response and T cell activity, and DEGs were enriched in signal pathways, such as T cell receptors. FYN and CD247 are in the centre of the protein-protein interaction network, and survival analysis found that they are positively correlated with survival from sepsis. Further, meta-analysis results showed that FYN could be useful for the prognosis of patients, and CD247 might distinguish between sepsis and systemic inflammatory response syndrome patients. Finally, RNA sequencing using a mouse septic shock model showed low expression of CD247 and FYN in this model.

CONCLUSION

FYN and CD247 are expected to become new biomarkers of septic shock.
