OBJECTIVEAlthough enhanced recovery after surgery (ERAS) programs have gained acceptance in various surgical specialties, no established neurosurgical ERAS protocol for patients undergoing elective craniotomy has been reported in the literature. Here, the authors describe the design, implementation, safety, and efficacy of a novel neurosurgical ERAS protocol for elective craniotomy in a tertiary care medical center located in China.METHODSA multidisciplinary neurosurgical ERAS protocol for elective craniotomy was developed based on the best available evidence. A total of 140 patients undergoing elective craniotomy between October 2016 and May 2017 were enrolled in a randomized clinical trial comparing this novel protocol to conventional neurosurgical perioperative management. The primary endpoint of this study was the postoperative hospital length of stay (LOS). Postoperative morbidity, perioperative complications, postoperative pain scores, postoperative nausea and vomiting, duration of urinary catheterization, time to first solid meal, and patient satisfaction were secondary endpoints.RESULTSThe median postoperative hospital LOS (4 days) was significantly shorter with the incorporation of the ERAS protocol than that with conventional perioperative management (7 days, p < 0.0001). No 30-day readmission or reoperation occurred in either group. More patients in the ERAS group reported mild pain (visual analog scale score 1–3) on postoperative day 1 than those in the control group (79% vs. 33%, OR 7.49, 95% CI 3.51–15.99, p < 0.0001). Similarly, more patients in the ERAS group had a shortened duration of pain (1–2 days; 53% vs. 17%, OR 0.64, 95% CI 0.29–1.37, p = 0.0001). The urinary catheter was removed within 6 hours after surgery in 74% patients in the ERAS group (OR 400.1, 95% CI 23.56–6796, p < 0.0001). The time to first oral liquid intake was a median of 8 hours in the ERAS group compared to 11 hours in the control group (p < 0.0001), and solid food intake occurred at a median of 24 hours in the ERAS group compared to 72 hours in the control group (p < 0.0001).CONCLUSIONSThis multidisciplinary, evidence-based, neurosurgical ERAS protocol for elective craniotomy appears to have significant benefits over conventional perioperative management. Implementation of ERAS is associated with a significant reduction in the postoperative hospital stay and an acceleration in recovery, without increasing complication rates related to elective craniotomy. Further evaluation of this protocol in large multicenter studies is warranted.Clinical trial registration no.: ChiCTR-INR-16009662 (chictr.org.cn)
Hepatocellular carcinoma (HCC) commonly emerges in an immunologically"cold" state, thereafter protects it away from cytolytic attack by tumor-infiltrating lymphocytes, resulting in poor response to immunotherapy. Herein, an acidic/photo-sensitive dendritic cell (DCs)-based neoantigen nano-vaccine has been explored to convert tumor immune "cold" state into "hot", and remodel tumor-associated neutrophils to potentiate anticancer immune response for enhancing immunotherapy efficiency. The nano-vaccine is constructed by SiPCCl 2 -hybridized mesoporous silica with coordination of Fe(III)-captopril, and coating with exfoliated membrane of matured DCs by H22-specific neoantigen stimulation. The nano-vaccines actively target H22 tumors and induce immunological cell death to boost tumor-associated antigen release by the generation of excess 1 O 2 through photodynamic therapy, which act as in situ tumor vaccination to strengthen antitumor T-cell response against primary H22 tumor growth. Interestingly, the nano-vaccines are also home to lymph nodes to directly induce the activation and proliferation of neoantigen-specific T cells to suppress the primary/distal tumor growth. Moreover, the acidic-triggered captopril release in tumor microenvironment can polarize the protumoral N2 phenotype neutrophils to antitumor N1 phenotype for improving the immune effects to achieve complete tumor regression (83%) in H22-bearing mice and prolong the survival time. This work provides an alternative approach for developing novel HCC immunotherapy strategies.
Previous studies have reported that telomere length in peripheral blood leukocytes can predict the clinical outcome of several cancers. However, whether leukocyte telomere length is associated with the prognosis of hepatocellular carcinoma (HCC) remains to be determined. In this study, relative telomere length (RTL) in peripheral blood leukocytes was measured using a real-time PCR-based method for 269 HCC patients treated with transarterial chemoembolization (TACE) from two independent hospitals. The association between RTL and the overall survival (OS) of HCC was analyzed. The immunological function of the HCC patients with different leukocyte RTLs was evaluated. Multivariate analyses indicated that long leukocyte RTL was significantly associated with poor OS of HCC patients, with a hazard ratio of 2.04 (95% confidence interval, 1.46-2.86; P< 0.001). Kaplan-Meier analyses showed a significant difference of median survival time between patients with long and short RTL (log rank P < 0.001). Fluorescence-activated cell sorting analyses showed that the long RTL group had a significantly increased percentage of CD4(+)CD25(+)FOXP3(+) Treg in CD4(+) T cells compared with short RTL group (P = 0.002). In conclusion, our results suggest that leukocyte RTL may serve as an independent prognostic marker for HCC patients treated with TACE.
ObjectiveTo evaluate patient satisfaction and associated predictors at discharge, as well as patient experience at 30-day follow-up, in a neurosurgical enhanced recovery after surgery (ERAS) programme.DesignA single-centre, prospective, randomised controlled study.SettingA tertiary hospital in China.ParticipantsA total of 140 neurosurgical patients aged 18–65 years old who had a single intracranial lesion and were admitted for elective craniotomy between October 2016 and July 2017 were included.InterventionsPatients were randomised into two groups: 70 patients received care according to a novel neurosurgical ERAS protocol (ERAS group) and 70 patients received conventional perioperative care (control group).Outcome measuresPatient satisfaction at discharge was evaluated using a multimodal questionnaire. A secondary analysis of patient experience regarding participation in the ERAS programme was conducted using a semistructured qualitative interview via telephone at 30-day follow-up.ResultsThe mean patient satisfaction was significantly higher in the ERAS group than in the control group at discharge (92.2±4.3 vs 86.8±7.4, p=0.0001). The most important predictors of patient satisfaction included age (OR=6.934), postoperative nausea and vomiting (PONV) Visual Analogue Scale (VAS) score (OR=0.184), absorbable skin suture (OR=0.007) and postoperative length of stay (LOS) (OR=0.765). Analysis on patient experience revealed five themes: information transfer, professional support, shared responsibility and active participation, readiness for discharge, and follow-up, all of which are closely related and represent positive and negative aspects.ConclusionsMeasures that include decreasing PONV VAS score, incorporating absorbable skin suture and shortening LOS seem to increase patient satisfaction in a neurosurgical ERAS programme. Analysis of data on patient experience highlights several aspects to achieve patient-centred and high-quality care. Further studies are warranted to standardise the assessment of patient satisfaction and experience in planning, employing and appraising the ERAS programme.Trial registration numberChiCTR-INR-16009662.
Background Previous studies have revealed that circadian genes play important roles in cell proliferation, apoptosis, cell cycle control, DNA damage response and treatment response of chemotherapy agents in cancers. Aims We hypothesized that the polymorphisms in circadian genes may be associated with prognosis of hepatocellular carcinoma (HCC) patients treated with transcatheter arterial chemoembolization (TACE). Methods Twelve functional single nucleotide polymorphisms (SNPs) in circadian negative feedback regulation genes (including CRY1, CRY2, PER1, PER2 and PER3) were genotyped using Sequenom iPLEX genotyping method in 337 HCC patients treated with TACE and analysed for associations with overall survival. Results Our data showed that one SNP rs2640908 in PER3 gene was significantly associated with overall survival of HCC patients (P = 0.027). Patients carrying at least one variant allele of rs2640908 (WV + VV) had a significantly decreased risk of death (hazard ratio, 0.71; 95% confidence interval, 0.53–0.90), when compared with those carrying homozygous wild‐type alleles (WW). Kaplan–Meier analyses showed a significantly longer median survival time in patients with WV + VV genotypes of SNP rs2640908 than those with WW genotype (11.6 months vs. 8.1 months; log rank P = 0.030). In addition, we also observed a significant difference on the genotype distribution of SNP rs2640908 in patients with and without portal vein thrombus (P = 0.041). Conclusions Our study provides the first evidence that a single functional polymorphism of PER3 gene is significantly associated with overall survival in HCC patients treated with TACE.
Small nuclear RNA host gene 7 (SNHG7), a novel long non-coding RNA (lncRNA), acts as an oncogene in cancers. However, whether SNHG7 is involved in hepatic stellate cell (HSC) activation during liver fibrosis is still unclear. In this study, upregulation of SNHG7 was found in vivo and in vitro during liver fibrosis. Silencing of SNHG7 led to the suppression of HSC activation, with a reduction in cell proliferation and collagen expression. SNHG7 knockdown also resulted in the suppression of liver fibrosis in vivo . Interestingly, miR-378a-3p was a target of SNHG7. SNHG7 and miR-378a-3p were co-located in the cytoplasm. Downregulation of miR-378a-3p blocked down the effects of loss of SNHG7 on HSC activation. Notably, SNHG7 could enhance Wnt/β-catenin pathway activation to contribute to liver fibrosis, with an increase in T cell factor (TCF) activity and a reduction in P-β-catenin level. It was found that miR-378a-mediated dishevelled segment polarity protein 2 (DVL2) was responsible for SNHG7-activated Wnt/β-catenin pathway. DVL2 was confirmed as a target of miR-378a-3p. SNHG7-induced HSC activation was almost blocked down by DVL2 knockdown. Accordingly, enhanced Wnt/β-catenin by SNHG7 was suppressed by loss of DVL2. Collectively, we demonstrate that SNHG7 reduces miR-378a-3p and attenuates its control on DVL2, leading to aberrant Wnt/β-catenin activity, which contributes to liver fibrosis progression.
Objective: To prospectively evaluate the efficacy of a neurosurgical enhanced recovery after surgery (ERAS) protocol on the management of postoperative pain after elective craniotomies. Methods: This randomized controlled trial was conducted in the neurosurgical center of Tangdu Hospital (Fourth Military Medical University, Xi'an, China). A total of 129 patients undergoing craniotomies between October 2016 and July 2017 were enrolled in a randomized clinical trial comparing an ERAS protocol to a conventional postoperative care regimen. The primary outcome was the postoperative pain score assessed by a verbal numerical rating scale (NRS). Results: Patients in the ERAS group had a significant reduction in their postoperative pain scores on POD 1 compared to patients in the control group (p < 0.05). More patients (n = 44, 68.8%) in the ERAS group experienced mild pain (NRS: 1 to 3) on POD1 compared with patients (n = 23, 35.4%) in the control group (p < 0.05). A further reduction in pain scores was also observed on POD 2 and maintained on POD 3 in the ERAS group compared with that in the control group. In addition, the median postoperative length of hospital stay was significantly decreased with the incorporation of the ERAS protocol compared to controls (ERAS: 4 days, control: 7 days, P<0.001). Conclusion: The implementation of a neurosurgical ERAS protocol for elective craniotomy patients has significant benefits in alleviating postoperative pain and enhancing recovery leading to early discharge after surgery compared to conventional care. Further evaluation of this protocol in larger, multi-center studies is warranted.
