The Impact of Spiritual Leadership on Employee’s Work Engagement–A Study Based on the Mediating Effect of Goal Self-Concordance and Self-Efficacy

The average stress of people in China’s workplace is reaching the peak in recent two years. To improve employee’s positive psychological factors, Spiritual leadership has a good performance in this regard. Based on the mediating effect of goal self-concordance and self-efficacy, this paper further studies the impact of spiritual leadership on employee’s work engagement. Through the empirical study, the following conclusions are drawn: (1) Spiritual leadership significantly positively affects the employee’s work engagement. (2) Spiritual leadership has a significant positive effect on goal self-concordance and self-efficacy. (3) Goal self-concordance and self-efficacy have significant positive effects on employee’s work engagement. (4) Goal self-concordance and self-efficacy play a partial mediating role in the process of spiritual leadership’s impact on employees’ work engagement. This study found the new mediator which partly revealed the mechanism between the effectiveness of Spiritual Leadership and employee’s work engagement. This study may serve as one of the researches for improving the effectiveness of leaders in organizations and promoting the motivation of employees in the workplace.

Utility of the INTERMACS profile at the time of assessment for heart transplant

The Interagency Registry of Mechanically Assisted Circulatory Support (INTERMACS) profiles are associated with mortality in heart failure patients undergoing ventricular assist device (VAD) implantation and heart transplantation (HTx). We assessed the prognostic value of the INTERMACS profile at the time of assessment for HTx or durable VAD implantation as bridge to candidacy (BTC). A total of 503 consecutive patients considered for HTx or VAD between 2006 and 2016 were included. The associations between INTERMACS profile and (a) waitlist mortality or delisting, (b) probability of HTx, and (c) overall mortality or delisting were evaluated using multivariable analysis. Median follow-up time was 2.9 years (IQR: 0.9-5.5) during which 184 received VAD, 347 received HTx, and 73 died (27 waitlist, 46 post-transplant). INTERMACS I-II profile was associated with higher waitlist mortality or delisting (HR: 3.83, 95% CI: 1.22-12.03), and this risk was reversed by VAD implantation (HR: 0.12, 95% CI: 0.03-0.50). INTERMACS III-IV profile was associated with a higher probability of HTx (HR: 1.82, 95% CI: 1.37-2.40). INTERMACS profile was not associated with the composite outcome of overall mortality or delisting. These results emphasize the prognostic utility of INTERMACS at time of decision for advanced therapies and its potential value in selecting patients for different interventions.

输尿管软镜碎石术治疗上尿路结石的疗效和安全性

目的探讨输尿管软镜碎石术(retrograde intrarenal stone surgery,RIRS)治疗上尿路结石的疗效和安全性。方法回顾性分析2016年4月至2019年1月武汉大学人民医院行RIRS的640例上尿路结石患者的临床资料。男424例,女216例。年龄(46.2±12.8)岁。结石最大径(1.4±0.7)cm。肾下盏结石126例,非肾下盏结石514例。单侧输尿管上段结石196例,单侧输尿管上段结石合并肾结石118例,单侧肾结石236例,双肾结石90例。104例术前留置双J管。马蹄肾8例,孤立肾合并肾功能不全30例,盆腔异位肾合并旋转不良4例,先天性输尿管畸形6例,海绵肾2例。术前血红蛋白(133.2±5.6)g/L,血清肌酐(84.4±12.2)μmol/L。手术均采用全麻,患者取截石位。采用输尿管软镜联合钬激光碎石,软镜顺利进入肾盂后首先观察肾盂及各肾盏并寻及结石。使用200μm光纤碎石,钬激光功率为12~45 W(0.5~1.5 J/10~30 Hz),根据实际情况辅助取石网篮套取结石。术中检查各肾盂、肾盏,确保结石已完全粉末化(结石最大径<0.3 cm),留置双J管和尿管。手术均由同等资历的术者完成。结果所有手术均顺利完成,手术时间(45.6±14.6)min。术后第1天复查血清肌酐(76.0±10.6)μmol/L,与术前比较差异有统计学意义(t=64.76,P<0.05);血红蛋白(126.4±9.6)g/L,与术前比较差异无统计学意义(t=2.02,P=0.064)。术后住院时间(4.8±1.5)d。术后3例(0.9%)发生严重并发症,分别为2例脓毒血症,1例包膜下血肿。术后3个月596例获得随访,其中552例达到结石清除标准,结石清除率(stone-free rate,SFR)为92.6%;余44例未达到结石清除标准者采用体外冲击波碎石、再次输尿管软镜手术或拔除双J管后观察。结石大小(χ^2=29.569,P<0.05)和位置(χ^2=44.949,P<0.05)是SFR的影响因素。多因素回归分析结果显示结石大小不是影响SFR的独立危险因素(P=0.639),结石位置是影响SFR的独立危险因素(P=0.013)。结论RIRS对于上尿路中小结石患者是一种可靠的治疗方式,疗效确切,并发症少,安全性高。但对于大结石及肾下盏结石的治疗还存在一定的局限性。肾下盏结石是影响RIRS疗效的独立危险因素。     

High expression levels of centromere protein A plus upregulation of the phosphatidylinositol 3-kinase/Akt/mammalian target of rapamycin signaling pathway affect chemotherapy response and prognosis in patients with breast cancer

Centromere proteins (CENPs) are involved in mitosis, and CENP gene expression levels are associated with chemotherapy responses in patients with breast cancer. The present study aimed to examine the roles and underlying mechanisms of the effects of CENP genes on chemotherapy responses and breast cancer prognosis. Using data obtained from the Gene Expression Omnibus (GEO) database, correlation and Cox multivariate regression analyses were used to determine the CENP genes associated with chemotherapy responses and survival in patients with breast cancer. Weighted gene co-expression network and correlation analyses were used to determine the gene modules co-expressed with the identified genes and the differential expression of gene modules associated with the pathological complete response (PCR) and residual disease (RD) subgroups. CENPA, CENPE, CENPF, CENPI, CENPJ and CENPN were associated with a high nuclear grade and low estrogen and progesterone receptor expression levels. In addition, CENPA, CENPB, CENPC and CENPO were independent factors affecting the distant relapse-free survival (DRFS) rates in patients with breast cancer. Patients with high expression levels of CENPA or CENPO exhibited poor prognoses, whereas those with high expression levels of CENPB or CENPC presented with favorable prognoses. For validation between databases, the Cancer Genome Atlas (TCGA) database analysis also revealed that CENPA, CENPB and CENPO exerted similar effects on overall survival. However, according to the multivariate analyses, only CENPA was an independent risk factor associated with DRFS in GEO database. In addition, in the RD subgroup, patients with higher CENPA expression levels had a worse prognosis compared with those with lower CENPA expression levels. Among patients with high expression levels of CENPA, the PI3K/Akt/mTOR pathway was more likely to be activated in the RD compared with the PCR subgroup. The same trend was observed in TCGA data. These results suggested that high CENPA expression levels plus upregulation of the PI3K/Akt/mTOR signaling pathway may affect DRFS in patients with breast cancer.
