The mothers' breastfeeding behaviour within six weeks postpartum: new scale development and psychometric validation study.

BACKGROUND: The evaluation of mothers' breastfeeding behaviour within 6 weeks postpartum could help health workers comprehensively identify maternal breastfeeding shortcomings, clarify nursing problems, and provide targeted interventions. However, no prior study was found, therefore this study aimed to develop and validate the reliability and validity of the mothers' breastfeeding behaviour scale within 6 weeks postpartum. METHODS: A main two-step approach was used: (1) a qualitative pilot study using the purposive sampling method was adopted to test the fitness, simplicity, and clarity of items with 30 mothers; (2) a cross-sectional survey using the convenient sampling method was conducted for item analysis and psychometric validation with 600 mothers. RESULTS: The final version of the scale consisted of 36 items with seven dimensions, explaining 68.852% of the total variance. The Cronbach's α, split-half, and retest coefficients were 0.958, 0.843, and 0.753, respectively. The validity of the scale: (1) Content validity: content validity index (CVI) range of items was between 0.882 and 1.000. The scale-level-CVI was 0.990. (2) Structure validity: The fitting indices were as follows: χ2/ⅆf =2.239, RMR = 0.049, RMSEA = 0.069, TLI = 0.893, CFI = 0.903, IFI = 0.904, PGFI = 0.674, and PNFI = 0.763. (3) Convergent validity: The composite reliability and average variance extracted (AVE) of the seven dimensions were between 0.876 and 0.920 and between 0.594 and 0.696. (4) Distinguish validity: The correlation coefficients were less than the square root of the AVE, except for self-decision behaviour, self-coping behaviour, and self-control behaviour. However, the fit index of the original three-factor model was better than that of the other new models, with significant differences (P < 0.001). (5) Calibration validity: The area under the curve was 0.860 or 0.898 when the scale was used to predict exclusive or any breastfeeding at 42 days. The correlation coefficients of the maternal breasting feeding evaluation scale, breastfeeding self-efficacy short-form scale, and the scale were 0.569 and 0.674, respectively. CONCLUSION: The newly developed mothers' breastfeeding behaviour scale within 6 weeks postpartum consists of 36 items belonging to seven dimensions with good reliability and validity and is a reliable and valid instrument to be used in future maternal breastfeeding behaviour assessments and interventions.

Clinical nurse adherence to professional ethics: A grounded theory.

BACKGROUND: Professional ethics is the regulation and discipline of nurses' daily nursing work. Nurses often encounter various ethical challenges and problems in their clinical work, but there are few studies on nurses' adherence to professional ethics. RESEARCH AIM: An analysis of nursing adherence to nursing ethics from the perspective of clinical nurses in the Chinese public health system. RESEARCH DESIGN: This study adopts the grounded theory approach proposed by Strauss and Corbin. PARTICIPANTS AND RESEARCH CONTEXT: Between July 2021 and January 2022, Clinical nurses were recruited for online video interviews using purposive and theoretical sampling methods in seven hospitals in Beijing, Tianjin, Shanxi, Henan, Guangdong, and Fujian, China. Data analysis was conducted using Strauss and Corbin's coding approach. ETHICAL CONSIDERATIONS: This study was approved by the Ethics Committee of Sanming First Hospital (MingYiLun 71/2021). FINDINGS: A total of 27 participants were included. A theoretical model of nursing staff adherence to professional ethics was constructed. The main core was adherence to professional ethics and the other cores were (1) causal conditions: professional ethics code, individual conscience; (2) intervening conditions: personal growth, social support system, matching career compensation, prediction of adverse consequences; (3) action strategies: sticking to professional values, self-regulation, flexible response, post-event improvement; and (4) outcomes: self-harmony, reduced medical disputes. CONCLUSIONS: This study provides an interpretive understanding of why clinical nurses adhere to professional ethics in China and describes the challenges and issues posed by nurses' use of strategies to cope with ethical adversity. The findings can be used to develop future complex studies.

Reliability and validity of the Mandarin version of the Trust in Nurses Scale.

AIMS: This study aimed to translate and validate the Trust in Nurses Scale (TINS) and then test and implement the tool. BACKGROUND: Trust is the core feature of the nurse-patient relationship, and a simple and universal instrument to measure patients' trust in nurses in China is lacking. METHODS: Exploratory and confirmatory factor analyses (EFA and CFA) were performed to verify structural validity. Content validity and reliability analyses were also conducted. RESULTS: The Cronbach's alpha of the TINS was .817, and the test-retest reliability coefficient was .852. EFA revealed two factors and explained 59.702% of the total variation. CFA proved that all the goodness-of-fit indicators were acceptable. CONCLUSION: The TINS exhibited satisfactory reliability and validity, and it can be universally applied to survey Chinese patients' trust in nurses. IMPLICATIONS FOR NURSING MANAGEMENT: The TINS can be used by nursing managers to assess patients' trust in nurses, and appropriate programmes can be developed to improve patients' trust.

Which mothers' breastfeeding behaviours within six weeks postpartum do health workers need to notice? Developing an indicator system based on the Delphi method and analytic hierarchy process.

OBJECTIVE: The six weeks postpartum is the high-incidence period of stopping breastfeeding. The clarity of the internal mechanism of behaviour was an effective way to promote breastfeeding. The aim was to reach a consensus on indicators what should be used and prioritised in evaluating mothers' breastfeeding behaviour within six weeks postpartum in order to provide a theoretical reference for health workers to take targeted strategies toward promoting breastfeeding practices. DESIGN: Two rounds of Delphi method and analytic hierarchy process was conducted in this study. The two-rounds Delphi was performed to select essential indicators and collect revised suggestion. The analytic hierarchy process was adopted for pairwise comparison to rank the significance of primary and secondary indicators. SETTING AND PARTICIPANTS: The panel included twenty experts with rich breastfeeding information and different general characteristics from China. FINDINGS: Consensus was achieved to include three primary indicators, seven secondary indicators, and forty-five tertiary indicators in the final indicators system of the mothers' breastfeeding behaviour within six weeks postpartum. The weight sequence of primary indicators was self-regulation behaviour (0.401), at-the-breast feeding behaviour (0.383), and resource utilisation behaviour (0.216). The rank of the secondary indicators was breastfeeding operation skills (0.267), self-decision behaviour (0.144), self-control behaviour (0.130), self-coping behaviour (0.127), breastfeeding self-perception (0.116), resource acquisition behaviour (0.115), and resource coordination behaviour (0.101). KEY CONCLUSION: The study builds a new and reliable indicators system that intuitively reflects the constituent elements of the mothers' breastfeeding behaviour within six weeks postpartum and provides priorities in primary indicators and secondary indicators. IMPLICATIONS FOR PRACTICES: The study helps form a clear and scientific cognition on mothers' breastfeeding behaviour within six weeks postpartum and provides a new perspective and intuitive theoretical reference for health workers to take targeted measures to promote breastfeeding practices and achieve substantial public health gains.

Research ability and research motivation of postgraduate nursing students in traditional Chinese medicine colleges.

AIM: To investigate the relationship between research ability and research motivation of postgraduate nursing students in traditional Chinese medicine colleges and identify other factors that may have an impact on the research ability of postgraduate nursing students. DESIGN: A cross-sectional electronic survey was used to collect data from 191 postgraduate nursing students. METHODS: A total of 191 postgraduate nursing students from seven traditional Chinese medicine colleges were investigated from October to November 2020 using self-rated scales for research ability and research motivation. The relationship between the variables affecting the research ability of postgraduate nursing students in traditional Chinese medicine colleges was determined. RESULTS: There was a positive correlation between the score of self-rated research ability and research motivation among 191 postgraduate nursing students in traditional Chinese medicine colleges. Multiple stepwise regression analysis showed that grade, research motivation, age and active participation in class discussions were the main factors affecting the self-rated research ability. CONCLUSION: The self-rated research ability of postgraduate nursing students in traditional Chinese medicine colleges is positively correlated with research motivation. According to the research motivation orientation, adopting targeted training methods and establishing correct professional understanding may improve the research ability of postgraduate nursing students.

The safety and efficacy of using moxibustion and or acupuncture for cancer-related insomnia: a systematic review and meta-analysis of randomised controlled trials.

INTRODUCTION: This study aimed to synthesise the best available evidence on the safety and efficacy of using moxibustion and/or acupuncture to manage cancer-related insomnia (CRI). METHODS: The PRISMA framework guided the review. Nine databases were searched from its inception to July 2020, published in English or Chinese. Randomised clinical trials (RCTs) of moxibustion and or acupuncture for the treatment of CRI were selected for inclusion. Methodological quality was assessed using the method suggested by the Cochrane collaboration. The Cochrane Review Manager was used to conduct a meta-analysis. RESULTS: Fourteen RCTs met the eligibility criteria. Twelve RCTs used the Pittsburgh Sleep Quality Index (PSQI) score as continuous data and a meta-analysis showed positive effects of moxibustion and or acupuncture (n = 997, mean difference (MD) = -1.84, 95% confidence interval (CI) = -2.75 to -0.94, p < 0.01). Five RCTs using continuous data and a meta-analysis in these studies also showed significant difference between two groups (n = 358, risk ratio (RR) = 0.45, 95% CI = 0.26-0.80, I 2 = 39%). CONCLUSION: The meta-analyses demonstrated that moxibustion and or acupuncture showed a positive effect in managing CRI. Such modalities could be considered an add-on option in the current CRI management regimen.

The diagnostic accuracy of mid-regional pro-adrenomedullin for sepsis: a systematic review and meta-analysis.

INTRODUCTION: The incidence and mortality of sepsis are high, and common biomarkers are not perfect. To identify a biomarker with high specificity and sensitivity for sepsis, we evaluated the current literature on the performance of mid-regional pro-adrenomedullin (MR-proADM) in the diagnosis of sepsis. EVIDENCE ACQUISITION: According to appropriate eligibility and exclusion criteria, PubMed, EMBASE, Cochrane Library, China Journal full-text Database, Wanfang Database and Chinese Journal Full Text Database were searched for "mid-regional pro-adrenomedullin," "MR-proADM," "sepsis," "pyemia," "pyohemia," "septicemia," and "blood poisoning." The publication dates considered for the search were from inception until August 31st, 2020. The risk of bias was assessed according to QUADAS-2 criteria. EVIDENCE SYNTHESIS: Eleven studies involving 2038 cases were included. MR-proADM had high sensitivity and specificity in the diagnosis of sepsis, with values of 0.83 (95% CI: 0.79-0.87) and 0.90 (95% CI: 0.83-0.94), respectively. The odds ratio of a combined diagnosis was 41.35, and the area under the curve (AUC) was 0.91. The best cut-off value for MR-proADM diagnosis of sepsis is 1-1.5 nmol/L. MR-proADM may also have value in distinguishing pathogens and identifying sepsis severity and organ failure. CONCLUSIONS: MR-proADM is an excellent biomarker for the diagnosis of sepsis with high sensitivity and specificity. The best cut-off value for MR-proADM diagnosis of sepsis is 1-1.5 nmol/L.

Development and Validation of a Resilience Questionnaire for Patients During Stroke Rehabilitation in China.

PURPOSE: The aim of the study was to develop a comprehensive questionnaire for assessing resilience in patients with stroke during rehabilitation and examine the questionnaire's reliability and validity. DESIGN: A four-phased design was used to develop and validate the questionnaire. METHODS: The preliminary items of the Resilience Questionnaire for Stroke Rehabilitation (RQSR) were generated through a literature review and a qualitative study. Twenty experts were consulted for content validation and modification of the questionnaire. A pilot study was conducted with 55 patients with stroke. A total of 510 participants from seven rehabilitation centers or hospitals were subsequently recruited to examine the psychometric properties of the RQSR. RESULTS: The RQSR consists of 35 items within three dimensions. Dimensions include effective rehabilitation training, accessible support system, and appropriate self-regulation. The content validity index of the total questionnaire was .9335. Seven factors were derived through factor analysis, and cumulative contribution rate of variance was 65.455%. Cronbach's alpha of the total questionnaire was .957, with each dimension ranging from .731 to .918, demonstrating high levels of reliability. CONCLUSION: The RQSR has sound reliability and validity and can be used as an appropriate tool for assessing resilience for patients with stroke during rehabilitation to facilitate effective interventions.

Gestational Diabetes Mellitus and Risk of Delayed Onset of Lactogenesis: A Systematic Review and Meta-Analysis.

Background: Gestational diabetes mellitus (GDM) may be associated with delayed onset of lactogenesis (DOL), but it is still inconclusive. Objectives: The study aimed to evaluate the association between GDM and DOL, the prevalence and risk factors of DOL in GDM women. Materials and Methods: A comprehensive search was performed in 10 electronic databases from inception to June 1, 2020. To find more eligible studies, the references of finally eligible studies and relevant reviews were traced manually. A meta-analysis was conducted to calculate the pooled estimates of association, prevalence, and risk factors using random- or fixed-effects models. Results: Eleven eligible articles involving 8,150 women were included in this study. GDM women had a higher risk of DOL (odds ratio [OR] = 1.84, 95% confidence interval [CI] [1.34-2.52]). The prevalence of delayed lactogenesis onset in GDM women was 35.0% (effect size [ES] = 0.35, 95% CI [0.30-0.40]). Primipara (OR = 2.54, 95% CI [1.89-3.42]), advanced age (OR = 1.05, 95% CI [1.03-1.08]), prepregnancy obesity (OR = 1.55, 95% CI [1.19-2.03]), and insulin treatment (OR = 3.07, 95% CI [1.71-5.47]) were risk factors of delayed lactogenesis onset in GDM women. Conclusion: GDM negatively affects the timing of lactogenesis onset. The prevalence of delayed lactogenesis onset in GDM women is 35.0%. Primipara, advanced age, prepregnancy obesity, and insulin treatment are independent risk factors of delayed lactogenesis onset in GDM women.

The effects of yam gruel on lowering fasted blood glucose in T2DM rats.

There is increasing evidence of the linkage between type 2 diabetes mellitus (T2DM) and gut microbiota. Based on our previous studies, we investigated the hypoglycemic mechanisms of yam gruel to provide a scientific basis for its popularization and application. Wistar rats were randomly divided into control and T2DM model groups. Rats in the model group were stimulated by a high-sugar/high-fat diet combined with an intraperitoneal injection of streptozotocin to induce T2DM. The T2DM rats were further subdivided randomly into three groups: (1) DM, (2) DM + yam gruel, and (3) DM + metformin. After 4 weeks of intervention, the changes in gut microbiota, short-chain fatty acids (SCFAs) (acetic acid, propionic acid, and butyric acid), the expression of G protein-coupled receptor 43 (GPR43), glucagon-like peptide-1 (GLP-1), peptide YY (PYY), and fasted blood glucose (FBG) levels were observed. Yam gruel intervention elevated the abundance of probiotic bacteria and increased the expression of SCFAs, GPR43 receptor, GLP-1, and PYY. It also reduced FBG levels. We conclude that yam gruel can lower FBG by promoting the growth of probiotic bacteria, increasing the content of SCFAs, and enhancing the expression of GPR43 receptor to increase the content of GLP-1 and PYY in serum.
