背景国内外用于评估癌症患者支持性照护需求的量表较多,但有关此类量表质量的标准化评价研究及不同量表间的横向比较研究较为缺乏,也少有研究者对此类量表的测量特性进行系统的整合与评价。目的评价中文版癌症患者支持性照护需求量表的测量学性能及研究的方法学质量。方法2021年4月检索中国知网、万方数据知识服务平台、维普中文科技期刊全文数据库、中国生物医学文献数据库、PubMed、EmBase、Web of Science、CINAHL Complete数据库,获取有关中文版癌症患者支持性照护需求量表测量学性能评价的研究,检索时限均为建库至2021年3月30日。由两位研究者独立筛选文献、提取资料后,采用健康测量工具遴选标准(COSMIN)系统综述指南,在对量表的测量特性及研究的方法学质量进行评价的基础上,综合评定中文版癌症患者支持性照护需求评估量表各测量特性的证据等级,并形成对于量表的最终推荐意见。采用描述分析法对评价结果进行汇总、分析。结果共纳入15项研究,涉及8个中文版癌症患者支持性照护需求评估量表〔癌症患者支持性照护需求简明问卷中文版(SCNS-SF34)、中文版支持性照护需求筛查工具(SCNS-ST9-C)、癌症患者综合需求评估量表(CNAT)、癌症需求简明问卷(CNQ-SF)、中文版癌症患者未满足需求量表(CaSUN-C)、癌症患者未满足需求简明量表(SF-SUNS)、晚期癌症患者需求评估问卷(ACNQ-41)、晚期癌症患者需求评估表简表(ACNQ-29)〕。就量表的测量特性质量而言,除ACNQ-29的内容效度为"未提及"外,其余7个量表的内容效度均为"不确定";除CaSUN-C、SF-SUNS的结构效度为"充分"外,其余6个量表的结构效度均为"不确定";SCNS-SF34、CNQ-SF、CaSUN-C、SF-SUNS的内部一致性为"充分",ACNQ-41的内部一致性为"不充分",其余3个量表的内部一致性为"不确定";CNAT、CNQ-SF、ACNQ-29的假设检验为"未提及",CaSUN-C、SF-SUNS、ACNQ-41的假设检验为"不确定",SCNS-SF34、SCNS-ST9-C的假设检验为"充分";除ACNQ-41的稳定性为"不充分",SCNS-ST9-C、ACNQ-29的稳定性为"未提及"外,其余5个量表的稳定性均为"充分";仅SCNS-SF34的跨文化效度为"充分",其余7个量表的跨文化效度均为"未提及"。8个量表的推荐等级均为B级。结论SCNS-SF34的测量特性得到了最为全面的评价,其具有较好的信效度,且临床应用可行性高,可暂时被推荐使用,但上述结论仍有待更多高质量证据加以支撑。 相似文献
ObjectiveAssess the biological and physicochemical properties of AH Plus, BioRoot RCS and Pulp Canal Sealer (PCS) leachates with and without chlorhexidine (CHX).MethodsThe sealers were studied in no contact and 1-minute contact with CHX. For biological properties (antibacterial activity and cytotoxicity), leachates were formed in saline of freshly mixed, 1-, 7- and 28 days set sealers. The antibacterial properties of sealer leachates were investigated for planktonic and biofilm growth of E. faecalis, S. mutans, S.epidermidis and S.aureus. The 3-(4,5 dimethylthiazolyl-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay was used to evaluate murine fibroblast cell viability after exposure to the leachates. The physical properties (water uptake, sorption, solubility, porosity, surface characteristics) of sealers and the pH of the immersion liquid (saline or distilled water) were also assessed over a 28-days period.ResultsCHX improved the antibacterial properties of the sealer leachates and reduced cell viability for all sealer leachates, except for freshly mixed PCS. BioRoot RCS leachates presented the highest antibacterial properties and cell viability with and without CHX contact. PCS was the material most affected by CHX in terms of physical properties, whereas for AH Plus, solubility was increased. CHX did not affect the physical properties of BioRoot RCS, except for solubility that was decreased. CHX contact did not change sealers’ alkalinity in distilled water whereas it increased it for AH Plus and BioRoot RCS in saline.SignificanceCHX improved the antibacterial efficacy of sealer leachates and either compromised or did not affect cell viability. CHX affected to various extent sealers’ physicochemical properties. 相似文献
ObjectivesDetermine criterion validity and intra/inter-rater reliability of 2-dimensional (2D) knee frontal plane projection angle (kFPPA), hip frontal plane projection angle (hFPPA), and dynamic valgus index (DVI) during forward step-downs in those with patellofemoral pain (PFP).DesignCross-sectional.SettingUniversity research laboratory.Participants39 participants with PFP (34.18 ± 7.41years, 170± .1 cm, 81.03 ± 19.36 kg, duration of pain: 68.67 ± 85.08months, anterior knee pain scale: 80.49 ± 7.87, visual analog scale:2.08 ± 2.02)Main outcome measuresAverage 3D hip and knee sagittal, frontal, and transverse joint angles and 2D kFPPA, hFPPA, and DVI at maximum knee flexion were variables of interest. 3D DVI was calculated as the sum of hip and knee frontal and transverse angles. 2D kFPPA, hFPPA, and DVI were calculated by two raters independently on two occasions.ResultsIntra- and inter-rater reliability of all 2D angles were excellent. kFPPA was moderately correlated to 3D knee transverse angles. hFPPA was moderately correlated to 3D hip frontal and transverse angles and largely correlated to 3D DVI. 2D DVI was moderately correlated to hip transverse angles.ConclusionkFPPA, hFPPA, and DVI are reliable. hFPPA may be reflective of 3D hip and knee frontal and transverse motion during forward step-downs in those with PFP. 相似文献
The frequently applied narrow and non-standard transverse dose profiles of intensity modulated photon-beam radiotherapy, lacking lateral secondary electron equilibrium, require the use of high-resolution dosimetry detectors, and small air-filled detectors are recommended as the reference detectors for cross-calibration of the high-resolution detectors. The present study focuses on the dosimetric properties of a novel cylindrical ionization chamber, the PTW Semiflex 3D 31021. The chamber's effective point of measurement was found to lie at (0.41 ± 0.04) r downstream the tip of the inner surface of the spherical front wall in the axial orientation and (0.46 ± 0.04) r upstream the chamber axis in the radial orientation. Due to its symmetrical design, the sigma values of its lateral dose response functions for all chamber's orientations are the same (2.10 ± 0.05 mm). The polarity correction factors obtained in this work do not exceed 0.1% and the saturation correction factor was below 1% up to a dose-per-pulse value of 0.956 mGy. The radiation quality correction factor kQ of the chamber as a function of the tissue-phantom-ratio, TPR20,10, has been calculated by Monte Carlo simulation and has been determined experimentally at the German Metrology Institute (Physikalisch-Technische Bundesanstalt, PTB). The values of the non-reference condition correction factor kNR have been Monte-Carlo-calculated for use of the chamber at various depths and field sizes. 相似文献
Background: There is a lack of occupation-focused instruments to assess Activities of Daily Living (ADL) that are intended for persons with mental disorders. The ADL Taxonomy is an instrument that is widely-used within clinical practice for persons with physical impairment. The aim of this study was to adapt the ADL Taxonomy for persons with mental disorders and evaluate its validity.
Methods: An expert group of Occupational Therapists (OTs) from psychiatric care adapted the ADL Taxonomy to fit the client group, including creating three new items. OTs in psychiatric care collected client data and evaluated the instrument for usability. Rasch analysis was used to evaluate the contruct validity of 16 activities separately.
Results: The OTs collected 123 assessments from clients with various mental disorders. Ten activities had excellent, and four had acceptable, psychometric properties with regard to item and person fit and unidimensionality. The activity managing the day/time gave complex results and would benefit from further development. The OTs found the test version intelligible, relevant and easy to use.
Conclusions: The ADL Taxonomy for persons with mental disorders has 16 activities with three to six actions each, and is now ready for clinical use. 相似文献
