Effect of Exercise on Fatigue in Patients Receiving Maintenance Hemodialysis Treatment: A Systematic Review and Network Meta-analysis.

OBJECTIVE: This study aimed to evaluate the effect of different exercises for improving fatigue in maintenance hemodialysis patients. DESIGN: PubMed, Embase, Web of Science, Cochrane, PEDro, CNKI, VIP, Wanfang data, CBM, and CINAHL were conducted from the establishment of the database to July 2023. We independently screened the literature, evaluated the quality, analyzed the data using Stata 15.0, and performed subgroup analysis on intervention time and exercise intervention adherence. RESULTS: Twenty-three studies were analyzed, with 1867 patients and nine interventions. Based on the surface under cumulative ranking curves and pairwise comparisons effects, overall long-term, short-term, and exercise intervention adherence >90% effects have all presented that during dialysis aerobic-resistance combined exercise was ranked as the most effective compared with routine care (surface under cumulative ranking curves = 83.9%, standardized mean difference = -1.45, 95% CI = -2.23 to -0.67; surface under cumulative ranking curves = 85.9%, standardized mean difference = -1.38, 95% CI = -2.24 to -0.52; surface under cumulative ranking curves = 86.6%, standardized mean difference = -1.54, 95% CI = -2.58 to -0.49; surface under cumulative ranking curves = 83.6%, standardized mean difference = -1.45, 95% CI = -2.25 to -0.66, respectively), followed by interdialytic period muscle relaxation exercise, interdialytic period aerobic-resistance combined exercise, interdialytic period aerobic exercise, and interdialytic period Baduanjin. CONCLUSIONS: Dialysis aerobic-resistance combined exercise may be considered in practice when resources allow. However, high-quality, multicenter, and large-sample randomized control trials must further verify this conclusion.

Effectiveness of nonpharmacological multi-component intervention on depressive symptoms in patients with mild cognitive impairment and dementia: A systematic review and meta-analysis.

Patients with mild cognitive impairment (MCI) and dementia are more prone to depression than people without MCI or dementia. Some studies have found nonpharmacological multi-component intervention to be more effective than single-component intervention in improving the condition of patients with MCI and dementia; however, their effect on depressive symptoms is still inconsistent. Therefore, it is necessary to explore the effectiveness of nonpharmacological multi-component intervention in improving depressive symptoms in patients with MCI and dementia. This review retrieved papers from PubMed, Embase, Cochrane Library, CINAHL, PsycINFO and CNKI. The retrieval time limit was set from 1 January 1990 to 25 November 2022. The PRISMA 2020 guideline was used to report the included studies. The result showed that nonpharmacological multi-component intervention could improve depressive symptoms in patients with MCI and dementia. Among them, nonpharmacological multi-component intervention with a duration of <6 months, physical and cognitive activities, or other activities had significant effects. However, each study differed in terms of specific measures, duration and frequency of intervention methods. Accordingly, more randomized controlled trials with larger samples are required to discover the best scheme for nonpharmacological multi-component intervention.

Prevalence, associated factors, and nursing practice-related outcomes of workplace violence towards nursing students in clinical practice: A systematic review and meta-analysis.

OBJECTIVES: To estimate the prevalence of Workplace violence (WPV) among nursing students in clinical practice, and examine the associated factors and nursing practice-related outcomes. DESIGN: A systematic review and meta-analysis. REVIEW METHODS AND DATA SOURCES: A comprehensive literature search was performed in nine databases from inception to Mar 2023. Two researchers independently screened studies, extracted data and assessed the quality of included studies. The random-effects model was used to estimate the pooled prevalence of WPV. Separate analyses were conducted by WPV type and source. RESULTS: 57 studies involving 23,451 nursing students were identified. The overall prevalence of WPV experienced and witnessed by nursing students was 45.37 % and 53.76 %, respectively, and 13.73 % were unsure if they had WPV. Psychological violence was the most prevalent form of WPV, but the prevalence of WPV also varied by setting and source, with obstetrics and gynaecology (41.25 %) being the most common settings and patients and their relatives (50.80 %) being the most common sources. When exposed to WPV, 65 % of nursing students did nothing except keep quiet, and 74 % did not report it. Concerning the associated factors of WPV, there were few reports on patient-related factors, and the selected studies focused primarily on nursing student- and occupational-related factors. Regarding nursing practice-related outcomes, WPV had a predominantly negative impact on nursing students' professional practice, but it also had a certain motivating effect. CONCLUSIONS: This meta-analysis estimates the global prevalence, associated factors, and nursing practice-related outcomes of WPV among nursing students. The findings confirm the high prevalence of WPV; therefore, schools and institutions should prioritize WPV education and training. The hospital should then formulate WPV laws and regulations, enhance the WPV reporting procedure, and protect the rights and interests of nursing students. Finally, hospital administrators should employ individualized intervention strategies for nursing students based on the variables that affect them.

Assessment tools for stigma in breast cancer patients based on COSMIN guidelines: a systematic review.

OBJECTIVE: The objective of this study was to conduct a systematic review of the measurement properties and methodological quality of stigma assessment tools designed for breast cancer patients. The aim was to provide clinical medical staff with a foundation for selecting high-quality assessment tools. METHODS: A comprehensive computer search was carried out across various databases, including SinoMed, China National Knowledge Infrastructure (CNKI), Wanfang Database, China Science and Technology Journal Database(VIP), Embase, PubMed, Web of Science, The Cochrane Library, and Scopus, which were searched from the inception of the databases until March 20, 2023. Literature screening and data extraction were performed independently by two researchers, adhering to predefined inclusion and exclusion criteria. The assessment tools were evaluated using the Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) systematic evaluation guidelines. RESULTS: In the final analysis, a total of 9 assessment tools were included. However, none of these tools addressed measurement error, cross-cultural validity, criterion validity, and responsiveness. Following the COSMIN guidelines, BCSS and CSPDS were assigned to Class A recommendations, while the remaining tools received Class B recommendations. CONCLUSION: The BCSS and CSPDS scales demonstrated comprehensive assessment in terms of their measurement characteristics, exhibiting good methodological quality, measurement attribute quality, and supporting evidence. Therefore, it is recommended to utilize these scales for evaluating breast cancer stigma. However, further validation is required for the remaining assessment tools.

Reliability and validity of the Chinese version of the trauma-specific frailty index (TSFI) for geriatric trauma patients.

BACKGROUND: Pre-traumatic frailty in geriatric trauma patients has caught attention from emergency medical workers and the assessment of it thus become one of the important aspects of risk management. Several tools are available to identify frailty, but limited tools have been validated for geriatric trauma patients in China to assess pre-traumatic frailty.The aim of this study is to translate the Trauma-Specific Frailty Index(TSFI) into Chinese, and to evaluate the reliability and validity of the translated version in geriatric trauma patients. METHODS: A cross-sectional study was conducted. The TSFI was translated with using the Brislin model, that included forward and backward translation. A total of 184 geriatric trauma patients were recruited by a convenience sampling between October and December 2020 in Hospital of Chengdu University of Traditional Chinese Medicine, Sichuan. Using reliability or internal consistency tests assessed with Cronbach's alpha coefficient, split-half reliability and test-retest reliability. Content validity and construct validity analysis were both performed. Sensitivity, specificity and maximum Youden index(YI) were used to determine the optimal cut-off value. The screening performance was examined by Kappa value. RESULTS: The total study population included 184 subjects, of which 8 participants were excluded, resulting in a study sample size of 176 elderly trauma patients (the completion rate was 95.7%). The Chinese version of Trauma-Specific Frailty Index(C-TSFI) have 15 items with 5 dimensions. Cronbach's alpha coefficient of the C-TSFI was 0.861, Cronbach's alpha coefficient of dimensions ranged from 0.837 to 0.875, the split-half reliability of the C-TSFI were 0.894 and 0.880 respectively, test-retest reliability ranged from 0.692 to 0.862. The correlation coefficient between items and the C-TSFI ranged from 0.439 to 0.761. The content validity index for items (I-CVI) of the C-TSFI scale was 0.86~1.00, and the scale of content validity index (S-CVI) was 0.93. The area under curve (AUC) of the C-TSFI was 0.932 (95%CI 0.904-0.96, P < 0.05), the maximum YI was 0.725, the sensitivity was 80.2%, the specificity was 92.3%, and the critical value was 0.31. Kappa value was 0.682 (P < 0.05). CONCLUSIONS: The Chinese version of TSFI could be used as a general assessment tool in geriatric trauma patients, and both its reliability and validity have been demonstrated.

Instruments for assessing the spiritual needs of cancer patients: A systematic review of psychometric properties.

AIMS AND OBJECTIVES: To identify available instruments for assessing cancer patients' spiritual needs and to examine their psychometric properties using the Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) methodology. BACKGROUND: Cancer patients frequently have significant spiritual needs. The nurse plays an integral role in assessing the patient's spiritual needs as part of providing holistic care. It is crucial to assess these needs using appropriate and reliable instruments. DESIGN: A systematic review based on COSMIN methodology. METHODS: Seven electronic databases (PubMed, EMBASE, CINAHL, Web of Science, ProQuest, CNKI and WANFANG) were systematically searched from inception until 14 February 2023. Two authors independently screened eligible literature, extracted data and evaluated methodological and psychometric quality. This systematic review was conducted following the PRISMA checklist. RESULTS: Sixteen studies have reported 16 different versions of the instruments. None of the instruments were properly assessed for all psychometric properties, nor were measurement error, responsiveness and cross-cultural validity/measurement invariance reported. All of the instruments failed to meet the COSMIN quality criteria for content validity. The quality of evidence for structural validity and/or internal consistency in five instruments did not meet the COSMIN criteria. Eventually, five instruments were not recommended, and 11 were only weakly recommended. CONCLUSION: Instruments to assess spiritual needs exhibited limited reliability and validity. The Spiritual Care Needs Scale is provisionally recommended for research and clinical settings, but its limitations regarding content validity and cross-cultural application must be considered in practice. Future research should further revise the content of available instruments and comprehensively and correctly test their psychometric properties. RELEVANCE TO CLINICAL PRACTICE: The review findings will provide evidence for healthcare professionals to select instruments for recognising spiritual needs in cancer patients. NO PATIENT OR PUBLIC CONTRIBUTION: This study is a systematic review with no patient or public participation.

The effect of psychological contract on turnover intention among nurses: a meta-analytic review.

BACKGROUND: The turnover intention (TI) of nurses is common, posing a threat to modern healthcare organizations. Psychological contract (PC) is a predictor of TI, affecting significantly nurse's TI. However, the extent of the association between PC and nurse's TI is unknown. We performed a meta-analysis to quantitatively analyze the relationship between PC and nurse's TI. METHODS: We searched nine electronic databases from inception to July 2023. Observational studies were included using a retrieval strategy related to PC and TI. Meta-analyses of common effect and random effect models were performed using R software with Spearman or Pearson correlation coefficients. Meta-regression, subgroup analysis, publication bias, and sensitivity analysis were also carried out . RESULTS: Eighteen studies including 8,908 nurses were identified. Based on various PC-related perspectives, 16 studies explored nurses' TI in terms of the content and three-dimensional structure of PC. Of these, 9 studies reported the negative direction of the correlation between PC and TI (r ranged from - 0.20 to -0.45), whereas 7 studies reported the positive direction of the correlation between PC and TI (r ranged from 0.32 to 0.50). The PC total and its dimensions were found to have moderately significant associations with TI, with the exception of the PCE and PCE-I. Additional, 2 studies reported the relationship between the outcome of PC and TI, the PCF, PCB, and PCV were powerful predictors of nurses' TI. Meta-regression and subgroup analysis found that only nurses working in specialized departments might be the source of heterogeneity. CONCLUSIONS: To our knowledge, this was the first meta-analysis to quantitatively examine the relationship between PC and TI among nurses. The findings reaffirmed the necessity for healthcare administrators and the medical profession to valued nurse' good interpersonal, social support, humanistic environment, and meet nurses' psychological and spiritual needs in addition to their material demands. Moderators of the connection between PC and TI, based on meta-regression and subgroup analyses, should be carefully explored as they may aid in identifying nurses' TI. Additional, longitudinal research, as well as mixed research, should be conducted to more comprehensively explore the relationship between PC and TI.

[Relationship Between Frailty and Poor Prognosis in Older Trauma Patients in the Emergency Department: A Prospective Cohort Study].

Objective: To explore the relationship between frailty and adverse outcomes in older trauma patients in the emergency department. Methods: A prospective cohort study was conducted. Older trauma patients admitted to the emergency department of three tertiary-care hospitals in Chengdu between January 2021 and August 2021 were enrolled. The patients were divided into a frailty group and a non-frailty group according to their assessment results for Trauma-Specific Frailty Index (TSFI). The end points, including falls, readmission, and deaths, were documented during the 6-month follow-up. Cox risk regression model was used to analyze the relationship between frailty and adverse outcomes in older trauma patients in the emergency department. Results: A total of 375 older trauma patients in the emergency department were enrolled, including 131 in the frailty group and 244 in the non-frailty group. After 6 months of follow-up, the incidences of falls, readmission and deaths in older trauma patients in the emergency department were 18.93%, 14.40%, and 7.73%, respectively. The incidences of falls (28.24% vs. 13.93%, P=0.001), readmission (25.95% vs. 8.20%, P=0.000), and deaths (12.98% vs. 4.92%, P=0.005) in older trauma patients in the emergency department in the frailty group were higher than those in the non-frailty group. After adjusting for multiple confounding factors using the Cox regression model, the risks of falls (hazard ratio [ HR]=1.859, 95% confidence interval [ CI]: 1.070-3.230, P=0.028] and readmission ( HR=2.920, 95% CI: 1.537-5.547, P=0.001) were higher in the frailty group than those in the non-frailty group, but there was no significant difference in the risk of deaths between the frailty group and the non-frailty group. Conclusion: Frailty is a risk factor for falls and readmissions in older trauma patients in the emergency department and the association between frailty and the risk of deaths in older trauma patients in the emergency department needs to be validated by further studies.

A Protocol for Constructing a Rat Wound Model of Type 1 Diabetes.

A single high dose of streptozotocin injection followed by full-thickness skin excision on the dorsum of rats is a common method for constructing animal models of type 1 diabetic wounds. However, improper manipulation can lead to model instability and high mortality in rats. Unfortunately, there are few existing guidelines on type 1 diabetic wound modeling, and they lack detail and do not present specific reference strategies. Therefore, this protocol details the complete procedure for constructing a type 1 diabetic wound model and analyzes the progression and angiogenic characteristics of the diabetic wounds. Type 1 diabetic wound modeling involves the following steps: preparation of the streptozotocin injection, induction of type 1 diabetes mellitus, and construction of the wound model. The wound area was measured on day 7 and day 14 after wounding, and the skin tissues of the rats were extracted for histopathological and immunofluorescence analysis. The results revealed that type 1 diabetes mellitus induced by 55 mg/kg streptozotocin was associated with lower mortality and a high success rate. The blood glucose levels were relatively stable after 5 weeks of induction. The diabetic wound healing rate was significantly lower than that of normal wounds on day 7 and day 14 (p < 0.05), but both could reach more than 90% on day 14. Compared with the normal group, the epidermal layer closure of diabetic wounds on day 14 was incomplete and had delayed re-epithelialization and significantly lower angiogenesis (p < 0.01). The type 1 diabetic wound model constructed based on this protocol has the characteristics of chronic wound healing, including poor closure, delayed re-epithelialization, and decreased angiogenesis compared to normal rat wounds.

Relationship between social support and fear of cancer recurrence among Chinese cancer patients: A systematic review and meta-analysis.

Background: To quantitatively analyze the association between social support (SS) and fear of cancer recurrence (FCR) by reviewing current evidence from observational studies. Methods: A comprehensive literature search was performed in nine databases from inception to May 2022. Observational studies that used both SS and FCR as study variables were included. Regression coefficient (ß') and correlation coefficient (r) were calculated with R software. Subgroup analysis was utilized to investigate the degree of the relationship between SS and FCR as well as the impact of various forms of SS on FCR in cancer patients. Results: Thirty-seven studies involving 8,190 participants were identified. SS significantly reduced FCR risk [pooled ß' = -0.27, 95% confidence interval (CI) = -0.364 to -0.172], with moderate negative correlations (summary r = -0.52, 95% CI = -0.592 to -0.438). Meta-regression and subgroup analysis showed that types of cancer and study type were the source of heterogeneity. However, types of SS [actual SS, perceived social support (PSS), and others], source of actual SS, and source of PSS were not significant moderators. Conclusion: To the best of our knowledge, this is the first systematic review and meta-analysis to quantitatively investigate the association between SS and FCR in Chinese cancer patients using ß' and r coefficients. The results re-emphasized that social workers should enhance the use of SS by cancer patients and establish a sound SS system by either implementing more relevant research or developing targeted policies. Based on meta-regression and subgroup analyses, moderators of the association between SS and FCR should also be studied closely as they may help identify patients in need. In addition, longitudinal research, as well as mixed research, should be conducted to more comprehensively explore the relationship between SS and FCR.

Public perceptions on the application of artificial intelligence in healthcare: a qualitative meta-synthesis.

OBJECTIVES: Medical artificial intelligence (AI) has been used widely applied in clinical field due to its convenience and innovation. However, several policy and regulatory issues such as credibility, sharing of responsibility and ethics have raised concerns in the use of AI. It is therefore necessary to understand the general public's views on medical AI. Here, a meta-synthesis was conducted to analyse and summarise the public's understanding of the application of AI in the healthcare field, to provide recommendations for future use and management of AI in medical practice. DESIGN: This was a meta-synthesis of qualitative studies. METHOD: A search was performed on the following databases to identify studies published in English and Chinese: MEDLINE, CINAHL, Web of science, Cochrane library, Embase, PsycINFO, CNKI, Wanfang and VIP. The search was conducted from database inception to 25 December 2021. The meta-aggregation approach of JBI was used to summarise findings from qualitative studies, focusing on the public's perception of the application of AI in healthcare. RESULTS: Of the 5128 studies screened, 12 met the inclusion criteria, hence were incorporated into analysis. Three synthesised findings were used as the basis of our conclusions, including advantages of medical AI from the public's perspective, ethical and legal concerns about medical AI from the public's perspective, and public suggestions on the application of AI in medical field. CONCLUSION: Results showed that the public acknowledges the unique advantages and convenience of medical AI. Meanwhile, several concerns about the application of medical AI were observed, most of which involve ethical and legal issues. The standard application and reasonable supervision of medical AI is key to ensuring its effective utilisation. Based on the public's perspective, this analysis provides insights and suggestions for health managers on how to implement and apply medical AI smoothly, while ensuring safety in healthcare practice.

Prevalence and Risk Factors of Postdialysis Fatigue in Patients Under Maintenance Hemodialysis: A Systematic Review and Meta-Analysis.

PURPOSE: Despite the high prevalence of postdialysis fatigue (PDF) in maintenance hemodialysis patients, no meta-analysis on the prevalence and risk factors of PDF has yet been published. This study aimed to identify the prevalence of PDF and explore its related factors. METHODS: PubMed, Embase, CENTRAL, Web of Science, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and the four Chinese databases (National Knowledge Infrastructure [CNKI], Chinese Biomedical Literature database [SinoMed], Wanfang Digital Periodicals [WANFANG], and Chinese Science and Technology Periodicals [VIP] database) were searched from inception up to July 2022. This study was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. The articles were independently searched by two reviewers, and the relevant data were extracted. The Agency for Healthcare Research and Quality was used to assess the quality of the included studies. RESULTS: Thirteen articles with 2,118 participants were included. The pooled prevalence was 60.0%. The meta-analysis results revealed that the ultrafiltration volume, mean arterial pressure after dialysis, and good sleep quality were potentially associated with PDF, whereas only good sleep quality (odds ratio 0.24, 95% confidence interval 0.19-0.30) was significantly associated with PDF. CONCLUSION: PDF is common in maintenance hemodialysis patients, which is related to the ultrafiltration volume, sleep quality, and mean arterial pressure after dialysis. However, the mechanism underlying the risk factors and PDF remains unknown. Further research is warranted to investigate the risk factors, intervention, treatment, and mechanism in maintenance hemodialysis patients.

Risk factors for pulmonary infection in elderly patients with acute stroke: A meta-analysis.

Objective: The study aims to systematically evaluate the risk factors of pulmonary infection in elderly patients with acute stroke. Methods: PubMed, CENTRAL, CINAHL, Web of Science, Embase, and four Chinese databases (CNKI, SinoMed, VIP, and Wanfang databases) for studies involving risk factors of pulmonary infection in elderly patients with acute stroke were searched. Then, two researchers independently read the article titles and abstracts to screen the literature, extracted relevant research data, and evaluated the methodological quality. Finally, a meta-analysis was performed. Results: In total, fifteen studies were included, with medium and high-grade quality. Meta-analysis results showed: age [OR = 1.70, 95% CI (1.27, 2.29), P = 0.0004], type of stroke [OR = 1.30, 95% CI (1.21, 1.40), P < 0.00001], conscious disturbance [OR = 2.27, 95% CI (1.44, 3.58), P = 0.0004], dysphagia [OR = 3.24, 95% CI (2.06, 5.12), P < 0.00001], diabetes mellitus [OR = 2.35, 95% CI (1.23, 4.48), P = 0.010], hypertension [OR = 2.05, 95% CI (1.83, 2.31), P < 0.0001], chronic obstructive pulmonary disease (COPD) [OR = 2.69, 95% CI (1.90, 3.81), P < 0.00001], hyperlipidemia [OR = 1.29, 95% CI (1.19, 1.39), P < 0.00001], invasive procedure [OR = 3.37, 95% CI (2.30, 4.94), P < 0.00001], hospital stays [OR = 1.41, 95% CI (1.22, 1.62), P < 0.00001], bedridden time [OR = 1.51, 95% CI (1.36, 1.68), P < 0.00001], and National Institute of Health Stroke Scale (NIHSS) score [OR = 1.67, 95% CI (1.02, 2.75), P = 0.04] were independent risk factors. Glasgow Coma Scale (GCS) score was not a risk factor. However, the relationship between atrial fibrillation, smoking history, and pulmonary infection in elderly patients with acute stroke needs further proof. Conclusions: Age, type of stroke, conscious disturbance, dysphagia, diabetes mellitus, hypertension, COPD, hyperlipidemia, invasive procedure, hospital stays, bedridden time, and NIHSS score were risk factors for pulmonary infection in elderly patients with acute stroke.

Status of work alienation among nurses in China: A systematic review.

Background: Work alienation is a common feeling of estrangement from the work and its context. Nurses are prone to feel alienated due to the high risk of infection, heavy workload, and the persistence of stress at high levels. Work alienation has serious negative outcomes, organizationally as well as personally. In recent years, the issue of work alienation among nurses has received considerable attention in China, but no systematic reviews have yet been published and its epidemiological status among Chinese nurses remains unclear. Objective: To systematically evaluate the status and distribution characteristics of work alienation among nurses in China. Methods: CINAHL, Embase, Web of Science, PubMed, CENTRAL, Wanfang, SinoMed, CNKI, and VIP were searched for cross-sectional studies before 10 January 2022 on the current status of work alienation among nurses. Two investigators independently screened the articles, extracted the data, and evaluated the risk of literature bias. Stata16.0 software was used for analysis. Results: A total of 12 studies were included, with 7,265 nurses involved. Meta-analysis results showed that the score of work alienation was 35.43 [95%CI (31.82, 39.04)]. Subgroup analysis showed that the scores of male and female nurses were 37.62 and 35.79 respectively; the scores of junior, undergraduate, and graduate nurses were 34.90, 37.15, and 40.02 respectively; the scores of primary, intermediate, and senior nurses were 36.95, 35.38, and 33.11 respectively; the scores of unmarried and married nurses were 38.59 and 36.70 respectively; the scores of nurses who had worked for 1~ <6 years, 6~10 years, and more than 10 years were 37.46, 36.69, and 32.89 respectively; the scores of nurses with salary <5,000 yuan, 5,000~10,000 yuan, and more than 10,000 yuan were 40.25, 37.19 and 34.52 respectively; and the scores of nurses in emergency department and intensive care units, internal medicine, surgery, and pediatrics were 37.25, 38.73, 36.28, and 31.98 respectively. Conclusion: Chinese nurses had a moderate level of work alienation. The scores of nurses in the following categories were quite high: male, higher education levels, low-professional titles, unmarried, shorter clinical working time, lower income, working in internal medicine, and working in the emergency department and intensive care units. Managers should take effective measures as soon as possible to reduce the occurrence of nurses' sense of work alienation.

Health-related quality of life in breast cancer patients in Asia: A meta-analysis and systematic review.

Objectives: The primary purposes of this meta-analysis and systematic review were to evaluate the health-related quality of life (HRQoL) of Asian breast cancer (BC) patients to understand their holistic HRQoL level and provide medical and nursing recommendations to improve and preserve their quality of life. Methods: A comprehensive literature search was conducted to find cross-sectional studies published in Chinese and English concerning HRQoL in BC patients from the inceptions of databases to 14 March 2022. The databases consulted were PubMed, Web of Science, Embase, Cochrane, PsyclNFO, CINAHL, and CNKI. Literature screening, data extraction, risk bias assessment, and data synthesis were independently carried out by two researchers. The Endnote X9 and Stata 15.0 software programs were used during the meta-analysis process. Results: Out of the 8,563 studies identified, 23 cross-sectional studies involving 3,839 Asian BC patients were included in this meta-analysis. Two tools, namely, European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire C30 (EORTC QLQ-C30) and Quality of Life Questionnaire Breast Cancer module 23 (EORTC QLQ-BR23)-were used to evaluate the HRQoL of BC patients in Asia. The pooled mean of the global health status of Asian BC patients was 58.34 (95% confidence interval [CI]: 53.66-63.02). According to functional subscales of EORTC QLQ-C30 and EORTC QLQ-BR23, Asian BC patients suffered from the worst emotional functioning (pooled mean=66.38; 95% CI: 59.66-73.11) and sexual enjoyment (pooled mean=49.31; 95% CI: 31.97-63.36). In addition, fatigue (pooled mean=42.17; 95% CI: 34.46-49.88) and being upset by hair loss (pooled mean=48.38; 95% CI: 36.64-60.12) were the most obvious symptoms that Asian BC patients experienced according to the meta-analysis results of the EORTC QLQ-C30 and EORTC QLQ-BR23 symptom subscales. Conclusion: Asian BC patients experience a relatively low HRQoL due to the prominent decline in their body functions, as well as the unpleasant experiences caused by their symptoms. It is suggested that timely, appropriate, and targeted intervention should be provided in relation to the physical, psychological, and social aspects of Asian BC patients' lives to enhance their ability to function, relieve them of adverse symptoms, and improve their overall HRQoL.

A meta-analysis of nursing students' knowledge and attitudes about end-of-life care.

OBJECTIVES: To synthesize nursing students' knowledge and attitudes about end-of-life care and to identify strategic directions for optimizing end-of-life care education. DESIGN: A meta-analysis of observational studies. DATA SOURCES: PubMed, Web of Science, EMBASE, CINAHL, PsycINFO, MEDLINE, CNKI, and WANFANG 8 electronic databases in English and Chinese were systematically searched from inception until 10 April 2022. REVIEW METHODS: Two reviewers independently screened literature and extracted data using structured tables. The Agency for Healthcare Research and Quality (AHRQ) was used to appraise the methodological quality of included studies. The study outcomes were synthesized using a meta-analysis. RESULTS: 26 cross-sectional studies of medium or high quality from 13 countries met the eligibility criteria, involving 9749 nursing students. In our review, nursing students demonstrated insufficient knowledge about end-of-life care, with a pooled mean score of 7.50 (95 % CI: 6.55-8.45); of these, knowledge about philosophy and principles, psychosocial and spiritual care, and pain and symptom management were all deficient, with pooled mean scores of 1.49 (95 % CI: 0.78-2.21), 1.00 (95 % CI: 0.35-1.65), and 3.44 (95 % CI: 2.25-4.63), respectively. Conversely, nursing students showed positive attitudes toward end-of-life care, with a pooled mean score of 102.97 (95 % CI: 99.43-106.51). The subgroup analysis revealed that male nursing students had lower pooled mean scores for end-of-life care knowledge and attitudes. CONCLUSION: There is a mismatch between nursing students' knowledge and attitudes about end-of-life care, they have a positive attitude but lack the necessary knowledge. Male nursing students seem to have a greater deficit of knowledge and a relatively conservative attitude toward end-of-life care. These findings may provide a significant reference for nursing educators to adjust educational strategies promptly.

The prevalence of polycystic ovarian syndrome in Chinese women: a meta-analysis.

BACKGROUND: To estimate the prevalence of polycystic ovarian syndrome (PCOS) in Chinese women comprehensively and to provide references to prevent PCOS. METHODS: China National Knowledge Infrastructure, Wanfang Data, China Science and Technology Journal Database, Chinese Biology Medicine, PubMed, Embase, Web of Science, CENTRAL, CINAHL were searched to collect studies on the prevalence of PCOS from database inception from March 31, 2020. Two reviewers independently screened literature according to the inclusion and exclusion criteria of the articles, extracted data, and tested the risk of bias of the included studies. Then Stata 15.1 software performed a meta-analysis. Begg's and Egger's method were used to assess the risk of publication bias. RESULTS: A total of 69 studies were involved, including 154,599 participants, 12,845 patients developed PCOS. The prevalence of PCOS was 10.01% (95% CI: 8.31% to 11.89%). Subgroup analysis showed that the prevalence of PCOS in different regions was as follows: 13.35% in the west, 7.82% in the east, 14.24% in the middle, and 8.68% in the north-east. Subgroup analysis by occupation/status: the prevalence rates of workers, students, medical staff, cadres, farmers, staff, and service staff were respectively 10.37%, 16.37%, 13.97%, 6.05%, 7.05%, 8.05%, 9.05%. For individuals aged 10 to 20, between 21 and 30, 31 to 40, and above 40, the prevalence rate was 10.26%, 17.23%, 9.13%, 2.22%, respectively. The prevalence rates of PCOS 1995 to 2000 were 21.04%, from 2001 to 2005, was 5.86%, from 2006 to 2010 was 10.78%, from 2011 to 2015 was 11.44%, and during 2016 to 2020 was 5.79%. Hospital-based community-based and school-based studies were 13.41%, 5.95%, 3.01%. According to the subgroup analysis of the surveyed population, the prevalence of PCOS in the general population and infertility patients were 6.05% and 13.69%, respectively. CONCLUSIONS: The prevalence rate of PCOS is high in Chinese women, and the prevalence of PCOS varies with different regions, occupation/identity, age, time of publication, diagnostic criteria, survey time, and prevalence of the surveyed population.

Reliability, validity and responsiveness of the Mandarin (Simplified) Chinese version of the EORTC QLQ-OH45 among cancer patients.

PURPOSE: The goal of our study was to evaluate the reliability, validity, responsiveness and acceptability of the Mandarin (simplified) Chinese version of the EORTC QLQ-OH45. METHODS: From October 2017 to February 2018, 393 cancer patients were enrolled from three different hospitals in China. A forward and backward translation was made to develop the Mandarin (simplified) Chinese version of EORTC QLQ-OH15. The QLQ-C30 and QLQ-OH15 questionnaires (which we have assembled and named QLQ-OH45 in this paper) were self-administered. Results were statistically analysed using SPSS 21.0. The reliability and validity tests of the questionnaires were assessed by Cronbach's α coefficient, Pearson correlation test and Mann-Whitney U tests. Responsiveness to change was measured in an independent sample of patients with head and neck cancer undergoing surgery or radiotherapy or chemotherapy. RESULTS: An acceptable internal consistency reliability for most multiple-item scales was demonstrated, as Cronbach's α coefficients were greater than 0.7 for most multiple-item scales, excepting for cognitive functioning (0.36) and oral health-related QoL functioning (0.55). All domain's test-retest reliability coefficients (r) was higher than 0.8. Multi-trait scaling analysis showed good convergent and discriminant validity. A difference in the quality of life (QoL) between older (≥65 years) and younger (<65 years) groups of patients was showed by the known-group comparisons. Low correlations were found between the scales of the QLQ-OH15 and QLQ-C30 in all areas. CONCLUSION: The Mandarin (simplified) Chinese version of QLQ-OH45 demonstrates satisfactory psychometric properties and can be used to measure the oral health-related QoL (OHRQoL) for Chinese cancer patients.

Prevalence and risk factors of prolonged grief disorder among bereaved survivors seven years after the Wenchuan earthquake in China: A cross-sectional study.

BACKGROUND: This study aimed to determine the prevalence and predictive factors of prolonged grief disorder (PGD) among those bereaved by the Wenchuan earthquake in Southwestern China seven years after the event. METHODS: A cross-sectional survey based on census tracts was conducted on the bereaved earthquake survivors. Responses to the questionnaire regarding PGD and its potential associated factors were obtained either through face-to-face or telephone interview. PGD was screened by a validated Chinese version of the PGD questionnaire-13 (PG-13). Bivariate and multivariate regression analyses were used to determine the prevalence and associated risk factors of PGD. RESULTS: A total of 1464 bereaved earthquake survivors, with a response rate of 97.6%, were included in the study. Of the 1464 respondents studied, 124 (8.47%) were diagnosed with PGD. Multivariate regression analysis demonstrated that PGD in the bereaved earthquake individuals was significantly associated with several factors, including age, economic burden, close kinship with the deceased, and living with the deceased before the loss. Wenchuan earthquake bereaved aged 41-60 years were more likely to develop PGD compared to those aged younger than 40 or older than 60 (OR = 2.075, 95%CI = 1.297-3.319). Those who had a close kinship with the deceased had a higher tendency to develop PGD (OR = 5.144, 95%CI = 2.716-9.740). The odds of PGD among the earthquake bereaved with economic burdens were higher relative to those who did not experience an economic burden (OR = 8.123, 95%CI = 2.657-24.831). Those who living with the deceased before loss also had a higher tendency to develop PGD (OR = 0.179, 95%CI = 0.053-0.602). CONCLUSIONS: This study revealed that a significantly high proportion (8.47%) of the Wenchuan earthquake-bereaved remain grieving seven years after the event. Those diagnosed with PGD should receive appropriate interventions from clinical psychologists. The risk factors identified in this study are crucial for the early screening and prevention of PGD in future nursing and psycho-clinical practices.

[Acupoint plaster therapy with midnight-noon ebb-flow hour-prescription method for senile osteoporosis:a randomized controlled trial].

OBJECTIVE: To compare the clinical efficacy differences between acupoint plaster therapy with midnight-noon ebb-flow hour-prescription method and traditional acupoint plaster therapy for senile osteoporosis (SOP). METHODS: With randomized controlled blind design, 76 SOP patients with deficiency of liver and kidney syndrome were randomly divided into an observation group and a control group, 38 cases in each one. Based on oral administration of caltrate D, the patients in the observation group were treated with acupoint plaster therapy with midnight-noon ebb-flow hour-prescription method at Yingu (KI 10), Taixi (KI 3), Dazhong (KI 4), Fuliu (KI 7) and Zhiyin (BL 67), while the patients in the control group were treated with traditional acupoint plaster therapy. Each plaster therapy lasted for 6 h, once a day; there was an interval of 2 d after consecutive 5-day treatment; 4 weeks were taken as one course, and totally 2 courses were given. Visual analogue scale (VAS) and Oswestry Disability Index (ODI) were used to evaluate the pain and dysfunction before intervention, after 4 weeks and 8 weeks intervention. Osteoporosis symptom rating sale and quality of life questionnaire of the European foundation for Osteoporosis (QUALEFFO-41) were adopted to evaluate the TCM syndrome and quality of life before and after 8-week intervention. RESULTS: All the outcomes were significantly improved after treatment in the two groups (P<0.01,P<0.05); after 4 weeks and 8 weeks of treatment, the VAS and ODI in the observation group were lower than those in the control group (all P<0.05). Repeated ANOVA indicated the VAS and ODI were significant in group effect, time effect and interaction effect (all P<0.01). Further comparison showed that VAS and ODI at later time points were lower than those in the early time points (all P<0.01). After the treatment, the scores of TCM syndrome and QUALEFFO-41 in the observation group were lower than those in the control group (all P<0.05). The effective rate was 85.7% (30/35) in the observation group, which was superior to the effective rate in the control group[74.3%(26/35), P<0.05]. CONCLUSIONS: The acupoint plaster therapy with midnight-noon ebb-flow hour-prescription method is superior to traditional acupoint plaster therapy in improving pain, dysfunction, TCM syndrome and quality of life in SOP patients; in addition, its clinical efficacy is significant.
