Comparison of survival between adolescent and young adult vs older patients with hepatocellular carcinoma

BACKGROUNDDue to the special clinical features and biologic characteristics of adolescent and young adult (AYA) cancers, AYA cancers are different from cancers in children and elderly individuals. However, there are few reports on AYA hepatocellular carcinoma (HCC).AIMTo investigate the overall survival (OS) of AYA (15-39 years) and elderly (40-74 years) patients with HCC.METHODSThe data of all the HCC cases were extracted from the Surveillance, Epidemiology, and End Results database from 2004 to 2015 and were then divided into two groups based on age: AYA group (15-39 years) and older group (40-74 years). Kaplan-Meier curves and log-rank tests were used to compare the OS of the two groups. Propensity score matching (PSM) was employed to analyze the OS difference between the two groups. The Cox proportional hazards regression model was used to perform multivariate analysis to explore the risk factors for OS of HCC patients.RESULTSCompared to elderly cancer patients, AYA patients with HCC had a worse Surveillance, Epidemiology, and End Results stage, including the distant stage (22.1% vs 15.4%, P < 0.001), and a more advanced American Joint Committee on Cancer (AJCC) stage, including AJCC III and IV (49.2% vs 38.3%, P < 0.001), and were more likely to receive surgery (64.5% vs 47.5%, P < 0.001). Before PSM, the AYA group had a longer survival in months (median: 20.00, interquartile range [IQR]: 5.00-62.50) than the older group (median: 15.00, IQR: 4.00-40.00) (P < 0.001). After PSM, the AYA group still had a longer survival in months (median: 21.00, IQR: 5.00-64.50) than the older group (median: 18.00, IQR: 6.00-53.00) (P < 0.001). The Cox proportional hazards regression model showed that advanced age (hazard ratio [HR] = 1.405, 95%CI: 1.218-1.621, P < 0.001) was a risk factor for OS of HCC patients. In the subgroup analysis, the Cox proportional hazards regression model showed that in AJCC I/II HCC patients, advanced age (HR = 1.749, 95%CI: 1.352-2.263, P < 0.001) was a risk factor for OS, while it was not a risk factor in AJCC III/IV HCC patients (HR = 1.186, 95%CI: 0.997-1.410, P = 0.054) before PSM. After PSM, advanced age (HR = 1.891, 95%CI: 1.356-2.637, P < 0.001) was still a risk factor for OS in AJCC I/II HCC patients, but was not a risk factor for OS in AJCC III/IV HCC patients (HR = 1.192, 95%CI: 0.934-1.521, P = 0.157) after PSM.CONCLUSIONAYA patients with HCC have different clinical characteristics from older adults. In different AJCC stages, the two groups of patients have different OS: In AJCC I/II HCC patients, advanced age is a risk factor for OS, but it is not a risk factor for OS in the AJCC III/IV HCC patient group.     

临床路径教学法在ICU新进护士前3个月护理带教中的应用效果观察

目的探讨在ICU新进护士的前3个月护理带教中,采取临床路径教学法的效果。方法选取该院2016年1月—2018年1月ICU新进的60名护士为研究对象,将护士分成两组,即研究组与对照组,每组30名,对照组采取一对一的护理带教模式,研究组则采取临床路径教学法的护理带教模式,观察两组带教效果。结果护理带教后,研究组护士在理论与操作考核成绩上均要显著高于对照组(P<0.05);研究组新进护士对临床实践能力、应急能力、工作能力及学习兴趣的认可率均显著高于对照组(P<0.05)。结论针对ICU新进护士,在前3个月的护理带教中,实施临床路径教学法的带教模式,可显著提高护士理论与操作能力,且护士对护理带教模式的认可度也高。     

Study of different routes of immunization using outer membrane vesicles of Neisseria meningitidis B and comparison of two adjuvants

Outer membrane vesicles (OMVs) of Neisseria meningitidis contain important antigens to trigger an immune response against meningococci and have been studied as vaccines compounds. The immune response to a vaccine may be affected by its constitution and route of administration. Therefore, Swiss mice were immunized by different routes with OMVs of N. meningitidis B with dimethyl dioctadecyl ammonium bromide in bilayer fragments (DDA-BF) or aluminum hydroxide (AH) as adjuvants. The adjuvants and different routes were compared regarding the immune responses by ELISA, western blot, delayed type hypersensitivity (DTH) and histopathologic analysis. The antigenic preparation generated humoral and cellular immune responses. In quantitative analyzes, in general, AH was superior to DDA-BF. However, analysis such as IgG avidity index, bactericidal activity and immunoblot, revealed no important differences regarding the adjuvant or route of immunization. Regarding the parameters tested, it was not possible to define a superiority between the adjuvants and routes of immunization proposed by this study.     

层级质量控制在外科ICU护理管理中的应用

目的探讨在外科ICU护理管理中实施层级质量控制的效果。方法选择2016年1-12月为实施前,2018年1-12月为实施后,实施前后均选取50例外科ICU患者及护理人员为研究对象,对实施前后外科ICU护理管理质量进行观察。结果实施后外科护理人员在工作人员素质、环境管理、护理质量管理及质量总分上均显著高于实施前(P<0.05);实施后ICU患者对护理管理的总满意率为98.00%,明显高于实施前总满意率86.00%,差异有统计学意义(P<0.05)。结论在外科ICU护理管理中,实施层级质量控制的护理管理模式,可显著提高ICU病房护理治疗,提高患者的满意率,值得推广。
