Growing the peer workforce in rural mental health and social and emotional well-being services: A scoping review of the literature.

INTRODUCTION: Growing the mental health peer workforce holds promise for rural communities, but we currently lack an understanding of the guidance available to support the development, implementation and sustainability of this workforce in rural settings. OBJECTIVE: Study aims are to: (1) determine the extent and nature of the literature that provides guidance for growing the peer workforce in rural mental health services; and (2) identify and explore any guidance relevant to rural peer work services dedicated to First Nations communities, including those promoting social and emotional well-being within this body of literature. DESIGN: A scoping review method was employed to identify relevant peer-reviewed and grey literature published between 2013 and 2022 across PsychInfo, Medline, Embase and CINAHL, Scopus and Informit HealthInfoNet databases, as well as targeted organisation websites and Google Advanced Search. FINDINGS: A total of 26 unique studies/projects were included from the US, UK, Canada and Australia with public mental health, non-government/for purpose and private sector service settings represented in the literature. Grey literature, such as reports of evaluations and frameworks, formed the majority of included texts. While there is a lesser volume of rurally focused literature relative to the general peer work literature, this is a rich body of knowledge, which includes guidance concerning services dedicated to First Nations communities. Via synthesis critical considerations were identified for the development, implementation and sustainability of peer work in rural mental health services across six domains: 'Working with community members and stakeholders', 'Organisational culture and governance', Working with others and in teams, Professional expertise and experience, Being part of and working in the community and 'Local mental health services capacity'. DISCUSSION: While there are considerations relevant across a range of settings, the domains of: 'working with community members and stakeholders', 'being part of and working in the community' and 'local mental health services capacity', capture additional, distinct and nuanced challenges and opportunities for growing the peer work in rural services. CONCLUSION: The literature offers insights valuable for service planning, policy development and the allocation of resources to support rural peer workforce growth.

The revised JBI critical appraisal tool for the assessment of risk of bias for cohort studies.

Cohort studies are a robust analytical observational study design that explore the difference between two different cohorts on an outcome, differentiated by their exposure status. Despite being observational in nature, they are often included in systematic reviews of effectiveness, particularly when randomized controlled trials are limited or not feasible. Like all studies included in a systematic review, cohort studies must undergo a critical appraisal process to assess the extent to which a study has considered potential bias in its design, conduct, or analysis. Critical appraisal tools facilitate this evaluation. This paper introduces the revised critical appraisal tool for cohort studies, completed by the JBI Effectiveness Methodology Group (EMG), who are currently revising the suite of JBI critical appraisal tools for quantitative study designs. The revised tool responds to updates in methodological guidance from the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) Working Group and reporting guidance from PRISMA 2020, providing a robust framework for evaluating risk of bias in a cohort study. Transparent and rigorous assessment using this tool will assist reviewers in understanding the validity and relevance of the results and conclusions drawn from a systematic review that includes cohort studies. This may contribute to better evidence-based decision-making in health care. This paper discusses the key changes made to the tool, justifications for these changes, and provides practical guidance on how this tool should be interpreted and applied by systematic reviewers.

The Chinese Mandarin COMHON Index and Braden Scale to assess pressure injury risk in intensive care: An inter-rater reliability and convergent validity study.

BACKGROUND: The COMHON Index is an intensive-care-specific pressure injury risk assessment tool, which has demonstrated promising psychometric properties. It has been translated into Chinese Mandarin but requires inter-rater reliability testing and comparison to the standard care instrument (Braden Scale) before clinical use. OBJECTIVES: This study aimed to test and compare the inter-rater reliability and convergent validity of the Chinese Mandarin versions of the COMHON Index and Braden Scale. METHODS: The study was conducted in a Chinese comprehensive intensive care unit. Based on a sample size calculation, five registered nurse raters with at least 6-months experience independently conducted risk assessments for 20 adult patients using both the COMHON Index and Braden Scale. Intraclass correlations (ICC) for inter-rater reliability, standard errors of measurement (SEM), and minimally detectable change (MDC) were calculated. Convergent validity was assessed using Pearson Product Moment Correlation for sum scores and Spearman's rho for subscales. RESULTS: Inter-rater reliability of COMHON Index and Braden Scale sum scores was very high (ICC [1,1] = 0.973; [95% confidence interval 0.949-0.988]; SEM 0.54; MDC 1.50) and high (ICC [1,1] = 0.891; [95% confidence interval 0.793-0.951]; SEM 0.93; MDC 2.57), respectively. All COMHON-Index subscales demonstrated ICC values >0.6, whereas two Braden Scale subscales (Mobility, Activity) were below this threshold. Instrument sum scores were strongly correlated (Pearson's r = -0.76 [r2 = 0.58]; p < 0.001), as were three subscale item pairs (mobility rs= -0.56 [r2 = 0.32]; nutrition rs= -0.63 [r2 = 0.39]; level of consciousness/sensory perception rs= -0.67 [r2 = 0.45] p < 0.001). CONCLUSION: Both the COMHON Index and Braden Scale demonstrated high levels of inter-rater reliability and measured similar constructs. However, the COMHON Index demonstrated superior inter-rater reliability and the results suggest that it better detects changes in patient condition and subsequently pressure injury risk. Further testing is recommended.

Post-traumatic stress disorder in children after discharge from the pediatric intensive care unit: a scoping review.

As the prevalence of post-traumatic stress disorder (PTSD) among children discharged from pediatric intensive care unit (PICU) continues to rise, corresponding research efforts have also increased. This scoping review aimed to review the PTSD prevalence, influencing factors, and tools used for PTSD measurements in children discharged from the PICU. This review employed the five-stage framework proposed by Arksey and O'Malley. The data sources included PubMed, Web of Science, Ovid, ScienceDirect, Springer, Scopus, CNKI, and WANFANG. Studies in English or Chinese published up to September 2023 were eligible for inclusion. The search yielded a total of 3536 results, with 31 articles meeting the inclusion criteria. The included studies reported that the prevalence of PTSD ranged from a minimum of 13% to a maximum of 84.6%. Risk factors for PTSD included medical interventions, child-related factors, and family environment. A total of 17 assessment tools for PTSD in PICU patients were reported. Given the significance of PTSD in this pediatric population, further attention, research, and intervention are warranted to help alleviate the burden of PTSD.

An evidence-based breathing exercise intervention for chronic pain management in breast cancer survivors: A phase II randomized controlled trial.

OBJECTIVE: Explore the preliminary effects of a breathing exercise (BE) intervention on chronic pain among breast cancer survivors. METHODS: This two-parallel-arm, open-label pilot randomized controlled trial recruited 72 breast cancer survivors who were randomly allocated to either the control or intervention group (n = 36 each). Both groups received usual care and a pain information booklet, while the intervention group received 4 weeks of additional BE. The primary clinical outcome was measured using the Brief Pain Inventory (BPI), with secondary clinical outcomes measured by the Hospital Anxiety and Depression Scale (HADS), Quality of Life Patient/Cancer Survivor Version in Chinese (QOLCSV-C), and Functional Assessment of Cancer Therapy- Breast (FACT-B) immediately post-intervention and at 4-week follow-up. Both adjusted and unadjusted Generalized Estimating Equation models were utilized to assess the BE's potential effects, with safety assessed through participant self-report. RESULTS: Sixty-eight participants completed the study. Statistical significance was observed in BPI in both adjusted and unadjusted models at post-intervention and follow-up (p < 0.05). BE demonstrated positive effects on anxiety, depression and quality of life improvement across all measures and timepoints in both adjusted and unadjusted models (p < 0.05). The effect sizes were smaller in the adjusted model. Three mild transient discomforts were reported associated with BE practice including dizziness, tiredness and yawning, without requirement of medical treatment. No severe adverse events occurred. CONCLUSION: This BE intervention appears effective in alleviating chronic pain, anxiety and depression, and improving quality of life for breast cancer survivors. Fully powered large-scale studies are required to confirm its effects.

Understanding adherence to continuous positive airway pressure in patients with obstructive sleep apnea post-stroke: A prospective study based on the Andersen model.

Adherence to continuous positive airway pressure (CPAP) in patients with obstructive sleep apnea (OSA) post-stroke is often problematic, despite potential benefits. This study aimed to evaluate CPAP adherence in patients with OSA post-stroke based on the Andersen behavioral model of health services utilization. A total of 227 eligible participants were recruited from a Chinese hospital. After baseline assessment, participants were followed for 6 months to determine short-term CPAP adherence. Those with good short-term adherence were followed for an additional 6 months to explore long-term adherence and influencing factors. Short-term CPAP adherence rate was 33%. Being married or living with a partner, having an associate degree or baccalaureate degree or higher, and stronger health beliefs independently predicted short-term CPAP adherence. Only 25% of participants from the adherent group showed good long-term adherence. The factor associated with long-term CPAP adherence was participants not using alcohol. Adherence to CPAP is suboptimal among patients having OSA post-stroke. Addressing unfavorable predisposing factors and modifying health beliefs are suggested.

Excellent thermomagnetic power generation for harvesting waste heat via a second-order ferromagnetic transition.

Thermomagnetic generation (TMG), a promising technology to convert low-grade waste heat to electricity, utilizes high performance TMG materials. However, the drawbacks of large hysteresis, poor mechanical properties and inadequate service life hinder the practical applications. For the first time, we evaluated the effect of different phase transitions on the TMG performance by systematically comparing the TMG performance of three typical Heusler alloys with similar composition but different phase transitions. Ni2Mn1.4In0.6 exhibits second-order magnetic transition (SOMT) from the ferromagnetic (FM) to paramagnetic (PM) state around TC = 316 K without thermal hysteresis. It presents highly comprehensive TMG performance, which is not only better than those of other two Heusler alloys with different phase transitions, but also better than those of most typical TMG materials. The maximum power density (1752.3 mW m-3), cost index (2.78 µW per €), and power generation index PGI (8.91 × 10-4) of Ni2Mn1.4In0.6 are 1-5, 1-4, and 1-7 orders of magnitude higher than those of most typical reported materials, respectively. In addition, Ni2Mn1.4In0.6 with SOMT also shows some advantages that first-order magnetic transition (FOMT) materials do not have, such as zero hysteresis and a long-term service life. In contrast to the short lifetime of a few minutes for the materials with FOMT, Ni2Mn1.4In0.6 with SOMT can serve for one month or even longer with excellent cycling stability. Consequently, we conclude that the SOMT Ni2Mn1.4In0.6 Heusler alloy with good TMG performance as well as zero hysteresis and long service life can be a better candidate than FOMT materials for practical applications of TMG.

Effects of nonpharmacological interventions on symptom clusters in breast cancer survivors: A systematic review of randomized controlled trials.

Objective: To summarize nonpharmacological interventions and assess their effects on symptom clusters and quality of life (QoL) in breast cancer (BC) survivors. Methods: Seven English and three Chinese electronic databases and three clinical trial registries were searched from January 2001 to August 2023. A narrative approach was applied to summarize the data. The primary outcome was symptom clusters measured by any patient-reported questionnaires, and the secondary outcomes were QoL and intervention-related adverse events. Results: Six published articles, one thesis, and one ongoing trial involving 625 BC survivors were included. The fatigue-sleep disturbance-depression symptom cluster was the most frequently reported symptom cluster among BC survivors. The nonpharmacological interventions were potentially positive on symptom clusters and QoL among the BC survivors. However, some of the included studies exhibited methodological concerns (e.g., inadequate blinding and allocation concealment). The intervention protocols in only two studies were developed following a solid evidence-based approach. Adverse events related to the targeted interventions were reported in six included studies, with none performing a causality analysis. Conclusions: The nonpharmacological interventions could be promising strategies for alleviating symptom clusters in BC survivors. Future studies should adopt rigorously designed, randomized controlled trials to generate robust evidence. Systematic review registration: INPLASY202380028.

Quality appraisal and descriptive analysis of clinical practice guidelines for self-managed non-pharmacological interventions of cardiovascular diseases: a systematic review.

BACKGROUND: Cardiovascular diseases (CVDs) are the leading cause of death around the world. Most CVDs-related death can be prevented by the optimal management of risk factors such as unhealthy diet and physical inactivity. Clinical practice guidelines (CPGs) for CVDs, provide some evidence-based recommendations which help healthcare professionals to achieve the best care for patients with CVDs. This systematic review aims to appraise the methodological quality of CPGs systematically and summarize the recommendations of self-managed non-pharmacological interventions for the prevention and management of CVDs provided by the selected guidelines. METHODS: A comprehensive electronic literature search was conducted via six databases (PubMed, Medline, The Cochrane Library, Embase, CINAHL, and Web of Science), seven professional heart association websites, and nine guideline repositories. The Appraisal of Guidelines, Research and Evaluation II (AGREE II) instrument was adopted to critically appraise the methodological quality of the selected guidelines. Content analysis was used to summarise recommended self-managed non-pharmacological interventions for CVDs. RESULTS: Twenty-three CPGs regarding different CVDs were included, in which four guidelines of CVDs, three for coronary heart diseases, seven for heart failure, two for atrial fibrillation, three for stroke, three for peripheral arterial disease, and one for hypertrophic cardiomyopathy. Twenty CPGs were appraised as high quality, and three CPGs as moderate quality. All twenty-three CPGs were recommended for use with or without modification. The domain of "Editorial Independence" had the highest standardized percentage (93.47%), whereas the domain of "Applicability" had the lowest mean domain score of 75.41%. The content analysis findings summarised some common self-managed non-pharmacological interventions, which include healthy diet, physical activity, smoking cessation, alcohol control, and weight management. Healthy diet and physical acidity are the most common and agreed on self-managed interventions for patients with CVDs. There are some inconsistencies identified in the details of recommended interventions, the intervention itself, the grade of recommendation, and the supported level of evidence. CONCLUSION: The majority of the summarized non-pharmacological interventions were strongly recommended with moderate to high-quality levels of evidence. Healthcare professionals and researchers can adopt the results of this review to design self-managed non-pharmacological interventions for patients with CVDs.

ICD-11 post-traumatic stress disorder and complex post-traumatic stress disorder in mental health support-seeking former-serving Australian defence force veterans.

BACKGROUND: ICD-11 complex post-traumatic stress disorder is a more severe condition than post-traumatic stress disorder, and recent studies indicate it is more prevalent among military samples. In this study, we tested the psychometric properties of the International Trauma Questionnaire, assessed the relative prevalence rates of post-traumatic stress disorder and complex post-traumatic stress disorder in the sample population and explored relationships between complex post-traumatic stress disorder and post-traumatic stress disorder and a range of risk factors. METHODS: Survey participants (N = 189) were mental health support-seeking former-serving veterans of the Australian Defence Force (ADF) recruited from primary care. Confirmatory factor analysis was used to test the factorial validity of the International Trauma Questionnaire. RESULTS: The latent structure of the International Trauma Questionnaire was best represented by a two-factor second-order model consistent with the ICD-11 model of complex post-traumatic stress disorder. The International Trauma Questionnaire scale scores demonstrated excellent internal reliability. Overall, 9.1% (95% confidence interval = [4.8%, 13.5%]) met diagnostic requirements for post-traumatic stress disorder and an additional 51.4% (95% confidence interval = [44.0%, 58.9%]) met requirements for complex post-traumatic stress disorder. Those meeting diagnostic requirements for complex post-traumatic stress disorder were more likely to have served in the military for 15 years or longer, had a history of more traumatic life events and had the highest levels of depression, anxiety and stress symptoms. CONCLUSION: The International Trauma Questionnaire can effectively distinguish between post-traumatic stress disorder and complex post-traumatic stress disorder within primary care samples of Australian Defence Force veterans. A significantly greater proportion of Australian Defence Force veterans met criteria for complex post-traumatic stress disorder than post-traumatic stress disorder. Australian military mental health services should adopt the International Trauma Questionnaire to routinely screen for complex post-traumatic stress disorder and develop complex post-traumatic stress disorder specific interventions to promote recovery in Australian Defence Force veterans with complex post-traumatic stress disorder.

Improving success and retention of undergraduate nursing students from rural and remote Australia: A multimethod study protocol.

AIM: The aim of the proposed research is to develop, pilot and evaluate a novel, bespoke intervention with in-built consideration of the factors influencing attrition and barriers to retention for rural and remote undergraduate nursing students. BACKGROUND: There are high rates of attrition in nursing students with rural and remote backgrounds in Australia. However, there is a lack of understanding of what enables or impedes these students to progress in their studies and the strategies available to support them to become part of the nursing workforce. Addressing these gaps is critical to informing the efforts of those involved in nursing education, training and workforce planning. DESIGN: A multi-methods study. METHOD: A project involving a multi-methods approach will be undertaken at an Australian higher education institution. In the first exploratory study, interviews and student cohort data will be used to understand attrition and retention, influencing factors and barriers to retention among rural and remote undergraduate nursing students. Findings from this study will be used to guide the development and implementation of a novel tailored student support service targeted to increase retention for this cohort. In the final evaluation study, the attrition and retention outcomes of participating students will be examined via interviews, surveys and existing cohort retention data. EXPECTED RESULTS: The study will provide insights into the factors that can shape the retention experiences of rural and remote undergraduate nursing students and generate much needed evidence concerning what Higher Education Institutions can do to support the retention for this specific student cohort.

Educational programs and interventions for health care staff to prevent and manage aggressive behaviors in acute hospitals: a systematic review.

OBJECTIVE: The objective of this review was to determine the effect of educational programs that have been implemented in acute health care settings to manage or prevent aggressive behaviors toward staff perpetrated by patients, families, or visitors. INTRODUCTION: Health care staff working within acute-level and tertiary-level hospitals are at high risk of exposure to aggressive behaviors by patients, their family, or visitors. Negative staff and organizational impacts reported in the literature include individual psychological or emotional distress and severe harm, increased absenteeism, high staff turnover, and awarded compensation. Reports of this kind of occupational violence are increasing globally; therefore, strategies to address prevention and management are needed to mitigate the risk of harm to staff and the wider hospital service. Various educational activities have been implemented to address the issue, but the overall effect of these is unclear. INCLUSION CRITERIA: Experimental and quasi-experimental studies were considered for inclusion if they reported on an educational program or intervention for staff working within an acute hospital setting and aimed at managing or preventing occupational violence perpetrated by patients, family, or visitors. Reports of programs implemented to address occupational violence, whether verbal or physical, were included. Studies were excluded if they reported on upward violence or bullying, patients in psychiatric or dementia facilities, or pediatric patients, due to the specific care needs of these cohorts. METHODS: The following databases were searched: PubMed (PubMed Central), CINAHL (EBSCOhost), PsycINFO (EBSCOhost), Embase, ERIC (ProQuest), Cochrane Central Register of Controlled Trials (Cochrane Library), and Scopus. ProQuest Dissertations and Theses was searched for unpublished studies. To obtain a wider perspective of the issue, studies published in Chinese were also searched in WanFang Database, China National Knowledge Infrastructure, and Chongqing VIP. A date filter of 2008-2023 was applied in a deliberate effort to expand from previous work. No language filters were applied. The review was conducted in accordance with JBI methodology for systematic reviews of effectiveness, and reported as per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. RESULTS: The search process retrieved 4681 citations. A total of 32 studies representing 3246 health staff were included in the review. The studies were either before-and-after or pre-test/post-test study designs. Methodological quality of studies varied, with the main issues being absence of CIs within statistical analysis, limited detail on participant selection or attrition/non-response, and underreporting of confounding factors. Educational programs varied in content and duration. Content delivery across the studies also varied, with several didactic, role-play, debriefing, group work, and simulation exercises reported. While studies reported some improvement in self-reported confidence levels, results were mixed for other outcomes. Determining overall effect of included studies was challenging due to heterogeneity within and across studies with regard to intervention types, populations, measurement tools, and outcomes. CONCLUSIONS: This review is unable to determine which workplace educational programs had an effect on staff outcomes or on the number of occupational violence incidents. In the future, educators and researchers could use the findings of this review to guide the design of educational programs and employ measures that are comparable to their settings. REVIEW REGISTRATION: PROSPERO CRD42020190538. SUPPLEMENTAL DIGITAL CONTENT: A Chinese-language version of the abstract of this review is available [ http://links.lww.com/SRX/A33 ].

Quality of Life Among Chinese Child Survivors of Heart Failure After Discharge From Pediatric Intensive Care Unit.

INTRODUCTION: This study investigated the current quality of life (QOL) status and related influencing factors in children with heart failure in the pediatric intensive care unit (PICU). METHOD: One hundred eighty-three children admitted to the PICU with heart failure were consecutively sampled. They were assessed 3 months after discharge and compared with a control group of 160 healthy individuals. The Pediatric Quality of Life Inventory (version 4.0) and Children's Revised Impact of Event Scale were completed, and factors influencing QOL were analyzed. RESULTS: Three months after discharge, the PICU group reported lower average scores on the overall QOL and the physical and emotional functioning scales than the control group. In particular, posttraumatic stress disorder status, age, and caregiver educational level greatly influenced the PICU children's QOL. DISCUSSION: More interventions and attention are needed to improve the QOL for PICU heart failure patients after discharge.

Undergraduate nursing students challenge misconceptions towards men in nursing: A mixed-method study.

AIMS: To examine misconceptions towards men in nursing from the perspective of undergraduate nursing students. Specifically, this study sought to explore contributing factors of misconceptions and attributions of the success of men in nursing. DESIGN: A convergent parallel mixed-method study. METHODS: A national survey was conducted (July-September 2021). The quantitative data included demographics and responses to the Gender Misconceptions of Men in Nursing (GEMINI) scale. The qualitative data included responses to a provocative statement related to characteristics of men and their career in nursing. The GRAMMS guideline was used in reporting. RESULTS: Undergraduate nursing students (n = 1245) from 16 Australian schools of nursing responded to the survey. Quantitative analysis demonstrated that most students (96%) did not have misconceptions about men in nursing. Those who did were more likely to be men, born overseas, not in health-related employment and did not have nursing as their first choice. Four broad overarching main themes were generated in response to the statement that suggested men do not have the right attributes for nursing: (1) 'This is a very misandristic viewpoint'; (2) 'Compassion and intelligence are distributed in men and women equally'; (3) 'Men bring a different quality to nursing' (4) 'Anyone can be whatever they want to be'. CONCLUSION: Overall, nursing students did not have misconceptions about men in nursing, despite experiencing ongoing social stigma regarding archaic gender norms. The findings from this study indicate that the next-generation nurses were championing to challenge the gender stereotype and support the needs of a gender diverse society. IMPACT: Attitudes and misconceptions that elicit gender inequalities must be addressed with comprehensive strategies and de-gendered language and imagery within the profession, schools, workplaces and the media. Shifting culture and attitudes towards inclusion, values the diversity in the workforce and supports healthy workplace environments. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

Exploring approaches to contemporary clinical incident analysis methods within acute care settings: a scoping review protocol.

OBJECTIVE: This review will explore the literature on contemporary incident analysis methods used in acute hospital settings, identifying types and characteristics of these methods and how they are used to minimize, prevent, or learn from errors and improve patient safety. INTRODUCTION: Safety is a major focus in health care; however, despite best efforts, errors and incidents still occur, leading to harm or potential harm to patients, families, carers, staff, or the organization. Incident analysis methods aim to reduce risk of harm. Traditional methods have been criticized for failing to consider the complexity of health care and the dynamic nature of acute care settings. Alternative methodologies are being sought to achieve higher levels of patient safety and care quality care in hospitals. Learning from errors and communicating with those involved in incidents are key requirements in contemporary incident analysis. INCLUSION CRITERIA: This review will consider empirical research published since 2013, reporting on the use of clinical incident analysis methods within acute care settings. The review will explore ways in which consumers or stakeholders (eg, clinicians or other hospital workers, patients, families, carers, visitors) have been included in these analysis methods and how data have been used to support changes in the service or organization. METHODS: Following JBI methods and PRISMA-ScR reporting guidance, we will search PubMed, CINAHL (EBSCOhost), Embase, Scopus, the Cochrane Library, Web of Science, and ProQuest Dissertations and Theses. Studies will be reviewed independently, with results presented in tables, figures, and narrative summaries according to the concepts of interest.

Somatic acupressure for the fatigue-sleep disturbance-depression symptom cluster in breast cancer survivors: A phase II randomized controlled trial.

OBJECTIVE: To evaluate the feasibility of the somatic acupressure (SA) for managing the fatigue-sleep disturbance-depression symptom cluster (FSDSC) among breast cancer (BC) survivors and its preliminary effects. METHODS: In this Phase II randomized controlled trial (RCT), 51 participants were randomised evenly into the true SA group, sham SA group, and usual care group. All the participants received usual care. The two SA groups performed additional true or sham self-acupressure daily for seven weeks. The primary outcomes related to the assessment of participants' recruitment and compliance with study questionnaires and interventions. Clinical outcomes assessed the preliminary effects of SA on fatigue, sleep disturbance, depression, and quality of life. Semi-structured interviews were undertaken to capture participants' experiences of participating in this study. The statistical effects of the intervention on the outcomes were modelled in repeated measures ANOVA and adjusted generalized estimating equations. RESULTS: Forty-five participants completed the SA intervention. No adverse events were reported. Over 85% of the participants could sustain for 25 days or more and 15 min or more per session, but the adherence to the intervention requirement was yet to improve. The group by time effect of the FSDSC and depression were significant (p < 0.05). Qualitative findings showed that participants positively viewed SA as a beneficial strategy for symptom management. CONCLUSIONS: The SA intervention protocol and the trial procedures were feasible. The results demonstrated signs of improvements in targeted outcomes, and a full-scale RCT is warranted to validate the effects of SA on the FSDSC.

High-performance thermomagnetic generator controlled by a magnetocaloric switch.

Low grade waste heat accounts for ~65% of total waste heat, but conventional waste heat recovery technology exhibits low conversion efficiency for low grade waste heat recovery. Hence, we designed a thermomagnetic generator for such applications. Unlike its usual role as the coil core or big magnetic yoke in previous works, here the magnetocaloric material acts as a switch that controls the magnetic circuit. This makes it not only have the advantage of flux reversal of the pretzel-like topology, but also present a simpler design, lower magnetic stray field, and higher performance by using less magnetocaloric material than preceding devices. The effects of key structural and system parameters were studied through a combination of experiments and finite element simulations. The optimized max power density PDmax produced by our device is significantly higher than those of other existing active thermomagnetic, thermo, and pyroelectric generators. Such high performance shows the effectiveness of our topology design of magnetic circuit with magnetocaloric switch.

Quality of life patient/cancer survivor version in Chinese cancer survivors: A validation study.

Objective: To validate the Chinese version of the Quality of Life (QoL) Patient/Cancer Survivor Version (QOLCSV-C) for measuring QoL in Chinese cancer survivors. Methods: The study followed a seven-step research practice guideline for cross-cultural research instrument validation study including translation, adaptation, and psychometric assessment. A forward- and backward-translation procedure was approached, followed by cultural adaptation and acceptability assessment. For its psychometric properties, its concurrent validity with the Functional Assessment of Cancer Therapy-General (FACT-G) was examined with correlation analysis. The internal consistency (Cronbach's alpha) and item-total and item-subtotal correlations of the QOLCSV-C were obtained. Factor analyses were conducted. Floor and ceiling effects and the discriminant performance of the selected variables on QOLCSV-C score were also examined. Results: The QOLCSV-C was translated from the 41-item QOLCSV with four domains: psychological, physical, spiritual and social well-being. The content validity was excellent (CVI â€‹= â€‹1.00). Time spent to complete the QOLCSV-C was about 10 â€‹min. The QOLCSV-C was found easy to use, appropriate in length, and reflective of their QoL. The strong correlation between QOLCSV-C and FACT-G indicates a satisfactory concurrent validity (Spearman's rho â€‹= â€‹0.765, P â€‹< â€‹0.001, n â€‹= â€‹205). The overall internal consistency of the QOLCSV-C (Cronbach's alpha â€‹= â€‹0.888) and the split-half reliability (Spearman-Brown r â€‹= â€‹0.918) were excellent. Most of the items show moderate to strong item-total correlation. The exploratory factor analysis revealed a four-factor solution, and confirmatory factor analysis has a satisfactory model fit with indicative items. None of the total scores of QOLCSV-C reveal the floor or ceiling effect. For discriminant performance, variables demonstrating significant between-group differences include sleep quality, pain, fatigue, nausea, physical health, and financial burden. Conclusions: The QOLCSV-C is a reliable and valid instrument for measuring the QoL in Chinese cancer survivors. Future studies can explore the factor structure, gender universal or specific items, and significant predictors of QoL of cancer survivors in different cultures.
