Abstract

Objective

The aim of this study was to explore whether positive emotion mediates the relationship between job burnout and turnover intentions among Chinese nurses.

Methods

A cross-sectional survey was conducted in the present study. Full-time registered nurses (n = 150) from Grade A hospitals in Tianjin were surveyed. Pearson correlation, hierarchical regression analyses, and the Sobel test were used in the study.

Results

The results illustrated that positive emotion mediated the relationship between burnout and nurses’ turnover intention.

Conclusions

Nursing administrators should pay more attention to the benefits of positive emotions on working motivation. It is helpful to relieve burnout in the working process so that nurses are willing to remain in their current employment.

Abstract

Polypropylene/carbon nanotubes (PP/CNTs) nancomposites were prepared with a single screw extruder by adding maleic anhydride-grafted poplypropylene (PP-g-MAH) as compatibilizer to polypropylene (PP) with different amounts of carbon nanotubes (CNTs) in the range of 0.1–0.7 wt.%. Structure and morphology of the prepared samples were examined by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), polarizing light microscopy (PLM) and X-ray diffraction (XRD). The results showed that PP spherulites decreased in size when CNTs were introduced into the polymer. Mechanical properties of the samples were also studied. Tensile tests showed that with increasing amount of CNTs the strain at break decreased whereas the Young’s modulus was improved of 16.41 % to 36.05 % and tensile strength of 36.67 % to 64.70 % compared to pristine PP. The SEM microphotographs showed that majority of the CNTs were dispersed individually and oriented along the shear flow direction.

Abstract

Objective

This meta-analysis aims to evaluate the effects of traditional Chinese medicine (TCM) nursing combined with conventional nursing in patients with chronic obstructive pulmonary disease (COPD).

Methods

Data were collected from the databases of PubMed, Embase, the Cochrane Library, Web of Science, Google Scholar, China National Knowledge Infrastructure (CNKI), WanFang Data (WF) and VIP Database, including literature regarding the effects of TCM nursing combined with conventional nursing in patients with COPD published before January 2017. The Jadad scale was used to assess the quality of the eligible literature. The weighted mean differences and odds ratios were used to analyze St. George’s Respiratory Questionnaire (SGRQ) scores, pulmonary function, hospital stay, and clinical efficacy.

Results

Twenty-three randomized controlled trials comprising 3116 cases (TCM nursing combined with the conventional nursing group: 1559; conventional nursing group: 1557) met the inclusion criteria. TCM nursing combined with conventional nursing was associated with a lower SGRQ score, higher forced expiratory volume in 1 second (FEV1) value, higher FEV1/forced vital capacity (FVC) value, higher FEV1% value, higher FEV1 predicted value, shorter hospital stay, and preferable clinical efficacy.

Conclusions

TCM nursing combined with conventional nursing emphasized that dialectical nursing can be performed preferably in patients with COPD.

Abstract

Objective

The objective of this study was to evaluate the effect of empowerment education on depression level and laboratory indicators of patients treated with hemodialysis.

Methods

We searched databases including Cochrane Library, Web of Science, Embase, PubMed, Chinese Biomedical Literature Database (CBM), Chinese Academic Journals Full-text Database (CNKI), VIP, and Wanfang. We included all the researches about the application of empowerment education in patients treated with hemodialysis. We used RevMan 5.3 to analyze the data after assessing the quality of researches.

Results

We included 10 studies eventually. The results of meta-analysis showed that the self-efficacy [MD = 1.10, 95% confidence interval (CI; 0.71, 1.48), P < 0.01], depression [MD = -6.94, 95% CI (-8.53, -5.34), P < 0.01], serum creatinine [Scr; MD = -116.46, 95% CI (-171.90, -61.03), P < 0.01], albumin [Alb; MD = 2.93, 95% CI (2.00, 3.86), P < 0.01], and blood urea nitrogen [BUN; MD = -0.95, 95% CI (-1.89, -0.01), P = 0.05] in the empowerment education group had significantly statistical difference compared with those in the usual education group. However, there was no significant difference in hemoglobin [Hb; MD = 3.03, 95% CI (-0.64, 6.70), P = 0.11] between two groups.

Conclusions

Empowerment education can improve the self-efficacy in patients treated with hemodialysis, relieve depression, and improve Scr, Alb, and BUN. However, there is no significant improvement in Hb; it needs further exploration in clinical practice.

Abstract

Objective

To explore the effects of self-directed learning readiness and learning attitude on problem-solving ability among Chinese undergraduate nursing students.

Methods

A convenience sampling of 460 undergraduate nursing students was surveyed in Tianjin, China. Students who participated in the study completed a questionnaire that included social demographic questionnaire, Self-directed Learning Readiness Scale, Attitude to Learning Scale, and Social Problem-Solving Inventory. Pearson’s correlation analysis was performed to test the correlations among problem-solving ability, self-directed learning readiness, and learning attitude. Hierarchical linear regression analyses were performed to explore the mediating role of learning attitude.

Results

The results showed that learning attitude (r=0.338, P<0.01) and self-directed learning readiness (r=0.493, P<0.01) were positively correlated with problem-solving ability. Learning attitude played a partial intermediary role between self-directed learning readiness and problem-solving ability (F=74.227, P<0.01).

Conclusions

It is concluded that nursing educators should pay attention on students’ individual differences and take proper actions to inspire students’ self-directed learning readiness and learning attitude.

Abstract

Objective

Problem-solving should be a fundamental component of nursing education because it is a core ability for professional nurses. For more effective learning, nursing students must understand the relationship between self-directed learning readiness and problem-solving ability. The aim of this study was to investigate the relationships among self-directed learning readiness, problem-solving ability, and academic self-efficacy among undergraduate nursing students.

Methods

From November to December 2016, research was conducted among 500 nursing undergraduate students in Tianjin, China, using a self-directed learning readiness scale, an academic self-efficacy scale, a questionnaire related to problem-solving, and self-designed demographics. The response rate was 85.8%.

Results

For Chinese nursing students, self-directed learning readiness and academic self-efficacy reached a medium-to-high level, while problem-solving abilities were at a low level. There were significant positive correlations among the students’ self-directed learning readiness, academic self-efficacy, and problem-solving ability. Furthermore, academic self-efficacy demonstrated a mediating effect on the relationship between the students’ self-directed learning readiness and problem-solving ability.

Conclusions

To enhance students’ problem-solving ability, nursing educators should pay more attention to the positive impact of self-directed learning readiness and self-efficacy in nursing students’ education.

Abstract

Objective

To summarize and evaluate the evidence of guidelines and systematic reviews (SRs) of nonpharmacological interventions for mild cognitive impairment (MCI) to support the development of future guidelines and clinical decisions for MCI patients.

Methods

Scottish Intercollegiate Guideline Network (SIGN), National Institute for Health and Clinical Excellence (NICE), American Academy of Neurology (AAN), Registered Nurses Association of Ontario (RNAO), Web of Science, PubMed, Cochrane Library, CNAHL, VIP, China National Knowledge Infrastructure (CNKI), and Wanfang Database were searched for relevant publications, including guidelines and SRs, from January 2014 to March 2019. Two authors independently screened articles, extracted data, and assessed the publications for adherence to the inclusion criteria. Appraisal of Guidelines for Research and Evaluation (AGREE II) was used to assess the quality of the guidelines, and Assessment of Multiple Systematic Reviews (AMSTAR 2) was used to assess the quality of SRs. In addition, the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to evaluate the quality of outcomes.

Results

Thirty-two articles were retrieved, including 1 guideline and 31 SRs. Fourteen SRs of physical exercise for MCI, six articles describing cognitive interventions, four articles describing acupuncture, and seven articles assessing dietary interventions (including four articles employing a Mediterranean diet, one article using vitamin B supplementation, and two articles assessing the effects of tea, coffee, and caffeine) were included. The quality of the articles was very low for 4 (13%), low for 10 (32%), and moderate for 17 (55%).

Conclusions

Based on the evidence available to date, nonpharmacological interventions may improve the current cognitive function of persons with MCI. In particular, physical exercise, cognitive interventions, and acupuncture exerted promising effects. However, due to the limited number and quality of the included publications, additional high-quality reviews are needed to further confirm.
