Identifying quality indicators for home care services: a modified Delphi and Analytic Hierarchy Process study.

BACKGROUND: As the recipients of home care services, patients have the most direct and profound experience of service quality. There is limited knowledge as to quality indicators for home care services from patients' perspective. This study aimed to identify quality indicators for home care services based on the Service Quality model and determine the weights of these indicators. METHODS: A two-round Delphi survey and Analytic Hierarchy Process consultation were conducted to gather opinions from national experts on quality indicators for home care services developed on the basis of the Service Quality model. Consensus was defined as at least 80% agreement on the importance (important and very important) of indicators among experts. The Analytic Hierarchy Process was used to calculate the weight coefficients of the identified indicators. RESULTS: The response rate was 95.0% and 97.4% in the first and second round, respectively. After two rounds, five first-level (tangibility, reliability, responsiveness, assurance and empathy) and 23 second-level indicators were identified. The Kendall's W values were 0.54 and 0.40 for the first-level and second-level indicators (p < 0.001). The weight coefficients for the first-level and second-level indicators were 0.110-0.298 and 0.019-0.088, respectively. CONCLUSION: Quality indicators for home care services were identified based on the Service Quality model. These indicators can be used to evaluate the service quality of home care from patients' perspective and facilitate to determine work priorities and improve the quality of home care.

CRISPR/Cas9 mediated knockout of Amyellow-y gene results in melanization defect of the cuticle in adult Apis mellifera.

Visible genetic markers are critical to gene function studies using genome editing technology in insects. However, there is no report about visible phenotypic markers in Apis mellifera, which extremely influences the application of genomic editing in honey bees. Here, we cloned and characterized the Amyellow-y gene in A. mellifera. Stage expression profiles showed that Amyellow-y gene was highly expressed in 2-, 4-day-old pupae, and newly emerged bees, and a high expression level was detected in the leg, thorax, wing and sting. To understand its functional role in pigmentation, Amyellow-y edited honeybees were created using CRISPR/Cas9, and it was found that the black pigment was decreased in the cuticle of mosaic workers and mutant drones. In particular, mutant drones manifested an overall appearance of yellowish cuticle in the body and appendages, including antennae, wings and legs, indicating that mutagenesis induced by disruption of Amyellow-y with CRISPR/Cas9 are heritable. Furthermore, the expression levels of genes associated with melanin pigmentation was investigated in mutant and wild-type drones using quantitative reverse transcription PCR. Transcription levels of Amyellow-y and aaNAT decreased markedly in mutant drones than that in wild-type ones, whereas laccase 2 was significantly up-regulated. Our results provide the first evidence, to our knowledge, that CRISPR/Cas9 edited G1 mutant drones of A. mellifera have a dramatic body pigmentation defect that can be visualized in adults, suggesting that Amyellow-y may serve as a promising visible phenotypic marker for genome editing in honey bees.

[Citation analysis of Space Medicine & Medical Engineering].

OBJECTIVE: To evaluate the academic research level and the popularity of Space Medicine & Medical Engineering (SMME). METHOD: With the Chinese Medical Citation Index (CMCI), the amount and distribution of the originals of SMME, which were cited by the journal included in CMCI, were analyzed according to method of citation analysis. RESULT: The average of original papers cited by other researchers was 2.25, and this was more than other medical journals. The authors of these cited papers were from 13 Provinces in China, Beijing and Shannxi Province were in the front of this research area. There were 109 citing journals, and self-citing rate was 43.97%. CONCLUSION: A series of high quality papers has been published by the SMME, and its own edition characteristics keep its research level steady. Not only has the journal become an important information source of space medical engineering but also a core journal in medicine research as well.
