基于COSMIN指南对癌症患者支持性照护需求量表的系统评价

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。

A molecular perspective for the use of type IV tyrosine kinase inhibitors as anticancer therapeutics

Tyrosine kinases are enzymes that can transfer a phosphate group from ATP to a specific protein tyrosine, serine or threonine residue within a cell, operating as a switch that can turn ‘on’ and ‘off’ causing different physiological alterations in the body. Mutated kinases have been shown to display an equilibrium shift toward the activated state. Types I–III have been studied intensively leading to drugs like imatinib (type II), cobimetinib (type III), among others. It is the same scenario for types V–VII; however, there is a lacuna in information regarding type IV inhibitors, although recently some advances have surfaced. This review aims to accumulate the knowledge gained so far about type IV inhibitors.

目的探讨多元化联合教学模式在超声引导下疼痛介入治疗教学中的应用效果。方法选择2018年1月至2020年12月在北京大学第三医院疼痛科进修的30名医师作为研究对象,将其分为对照组与观察组;对照组采用常规教学模式;观察组采用多元化联合教学模式,比较两组医师技能考核成绩、教学质量评分和满意度评分。结果观察组医师技能考核成绩优良率为93.3%,高于对照组的73.3%(P<0.05);观察组医师对基础理论知识掌握、临床思维能力的提高、学习兴趣的激发、疾病诊治能力的提高4个方面的评分均高于对照组(P<0.01)。结论多元化联合教学模式可促进超声引导下疼痛介入治疗技能的提高,有利于提高学员的综合临床能力。     

Endodontics Specialists’ Practice during the Initial Outbreak of Coronavirus Disease 2019

IntroductionThe first outbreak of coronavirus disease 2019 (COVID-19) in the United States resulted in a nationwide closure of dental offices that created an oral health crisis. The aim of this observational study was to analyze and compare the characteristics of patients who visited 2 private endodontics offices from March 16 to May 31, 2020, compared with the same period in 2019.MethodsDemographic, diagnostic, and procedural data of 1520 (693 in 2020 and 827 in 2019) patient visits were collected. Bivariate and multiple logistic regression analyses were used to assess the impact of the COVID-19 outbreak on patient-related variables.ResultsBivariate analyses showed that the number of patient visits decreased in April and May 2020 (P < .0001). In 2020, patients’ self-reported pain level was higher, they were more frequently diagnosed with pulp necrosis and acute apical abscess, and they received more incisions for drainage (P < .05). Multiple logistic regression analyses showed that the COVID-19 outbreak was associated with less visits for older patients (>49.5 years) (odds ratio [OR] = 0.720; 95% confidence interval [CI], 0.573–0.906), more patients with kidney diseases (OR = 2.690; 95% CI, 1.143–6.331), higher levels of pain on percussion (OR = 2.277; 95% CI, 1.718–3.016), less cases with previously initiated treatment (OR = 0.242; 95% CI, 0.080–0.731), less periapical diagnoses of asymptomatic apical periodontitis (OR = 0.510; 95% CI, 0.306–0.849), and a higher number of nonsurgical root canal treatments (OR = 2.073; 95% CI, 1.397–3.074) and apicoectomies (OR = 2.799; 95% CI, 1.367-5.729).ConclusionsThese findings show that the public health burden of endodontic infections was more intense during the initial outbreak of COVID-19.

Bridging the gap between attitudes and action: A qualitative exploration of clinician and exercise professional’s perceptions to increase opportunities for exercise counselling and referral in cancer care

ObjectiveThis study aimed to 1) understand factors impacting the implementation of exercise communication and referral, and 2) explore integrated clinical approaches to exercise communication and referral in cancer care.MethodsSeven focus groups (N = 53) were conducted with clinicians and exercise professionals throughout Sydney, Australia. A sub-sample of participants (n = 9) attended a half-day workshop to identifying best practice approaches for moving forward. Data were analysed using thematic content analysis.ResultsTwo themes emerged: 1) Factors impacting the knowledge-to-action gap, inclusive of limited exercise specific knowledge and training opportunities, funding structure, and current referral process, and 2) Recommendations for a consistent and efficient way forward, detailing the need for oncologist-initiated communication, distribution of cancer-exercise resources, and access to exercise professionals with cancer expertise.ConclusionsThis study identified factors (e.g., cancer-exercise specific training, integration of exercise physiologists) influencing exercise counselling and referral. A potential implementation-referral approach accounting for these factors and how to incorporate exercise into a standard model of cancer care, is described. Future testing is required to determine feasibility and practicality of these approaches.Practical ImplicationsA pragmatic model is provided to guide implementation-referral, inclusive of oncologist-initiated communication exchange, relevant resources, and access to exercise professionals with cancer expertise.     

Delivering end-of-life care for patients with cancer at home: Interviews exploring the views and experiences of general practitioners

Many patients with terminal cancer wish to die at home and general practitioners in the United Kingdom have a critical role in providing this care. However, it has been suggested general practitioners lack confidence in end-of-life care. It is important to explore with general practitioners their experience and perspectives including feelings of confidence delivering end-of-life care to people with cancer. The aim of this study was to explore general practitioners experiences of providing end-of-life care for people with cancer in the home setting and their perceptions of confidence in this role as well as understanding implications this has on policy design. A qualitative study design was employed using semi-structured interviews and analysed using thematic analysis. Nineteen general practitioners from London were purposively sampled from eight general practices and a primary care university department in 2018–2019, supplemented with snowballing methods. Five main themes were constructed: (a) the subjective nature of defining palliative and end-of-life care; (b) importance of communication and managing expectations; (c) complexity in prescribing; (d) challenging nature of delivering end-of-life care; (e) the unclear role of primary care in palliative care. General practitioners viewed end-of-life care as challenging; specific difficulties surrounded communication and prescribing. These challenges coupled with a poorly defined role created a spread in perceived confidence. Experience and exposure were seen as enabling confidence. Specialist palliative care service expansion had important implications on deskilling of essential competencies and reducing confidence levels in general practitioners. This feeds into a complex cycle of causation, leading to further delegation of care.
