Aim: To synthesize self‐administrated needs assessment tools of informal caregivers for patients with chronic non‐communicable diseases (CNCDs), evaluate the quality of psychometric properties and identify main needs assessment themes. Design: Systematic review. Methods: Eight electronic databases both in English and Chinese were searched for. The psychometric properties of tools were evaluated according to the quality criteria for good psychometric properties developed by Terwee et al. Both the content analysis and thematic extraction methods were used. Needs assessment themes were categorized based on the 7‐level Maslow's Hierarchy of Needs Theory. Results: A total of 17 tools were synthesized. Thirteen of them targeted informal caregivers of patients with cancer. The psychometric properties evaluated for most of these tools were content validity, internal consistency and construct validity. A total of 27 needs themes were identified and matched to six levels based on the 7‐level Maslow's Hierarchy of Needs theory, besides the aesthetic needs level. No Patient or Public Contribution: No primary data are being collected. [ABSTRACT FROM AUTHOR]

A CeO2-doped plasma electrolytic oxidation (PEO) composite coating was prepared on the surface of Cu–Zn alloys by adding CeO2 nanoparticles into the mixed electrolytes of Na2SiO3·9H2O and sodium hydroxide. Surface microstructure and element composition of PEO coatings were studied by a scanning electron microscope (SEM) with energy-dispersive X-ray spectroscopy (EDS) and X-ray diffraction (XRD). Microstructure analysis showed that CeO2 nanoparticles were uniformly deposited on the sample surface, and most of the particles were embedded into PEO coatings. Ce element found in the EDS and XRD analysis confirmed the successful incorporation of CeO2 nanoparticles. Furthermore, with the addition of CeO2 nanoparticles, the coating porosity decreased gradually, while the thickness and surface roughness of PEO coatings decreased and then increased. Corrosion resistance of PEO coatings was investigated by using a potentiodynamic polarization test. The results show that the addition of CeO2 nanoparticles has significantly improved the corrosion resistance of PEO coatings. Especially, the corrosion current density of the PEO coating with 4 g/L CeO2 concentration is 3 orders of magnitude more than that of the bare alloy substrate. [ABSTRACT FROM AUTHOR]

Introduction: Previous studies have highlighted the experiences of caregivers for patients with chronic heart failure (CHF), specifically focusing on their negative experiences. There are few systematic reviews on the topic to synthesise the positive experiences of family caregivers for patients with CHF. This study will examine how experiences such as developing new skills, strengthening their relationships (between caregivers and recipients) and receiving appreciation from the care recipient assist to improve caregivers' perception of their circumstances., Methods and Analysis: This review will be conducted in accordance with the Joanna Briggs Institute (JBI) methodology for qualitative systematic reviews. Qualitative and mixed methods studies related to the positive experiences of family caregivers for patients with CHF, reported in English or Chinese and published from inception in the following databases will be included: PubMed, MEDLINE, Embase, Cochrane Library, Web of Science, PsycINFO, CINAHL, Wan Fang Data, China National Knowledge Infrastructure, Chongqing VIP, Chinese Biomedical Literature Database, Open Grey and Deep Blue Library databases. The standard JBI Critical Appraisal Checklist for Qualitative Research will be used by two independent reviewers to appraise the quality of the included studies, and the standardised JBI Qualitative Data Extraction Tool for Qualitative Research will be applied to extract data. The final synthesised findings will be graded according to the ConQual approach for establishing confidence in the output of qualitative research synthesis., Ethics and Dissemination: Ethical approval is not required as no primary data are being collected. The results will be made available through a peer-reviewed publication., Prospero Registration Number: CRD42021282159., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.
