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。

Immunogenicity of two doses of BNT162b2 and mRNA-1273 vaccines for solid cancer patients on treatment with or without a previous SARS-CoV-2 infection

Previous studies on the immunogenicity of SARS-CoV-2 mRNA vaccines showed a reduced seroconversion in cancer patients. The aim of our study is to evaluate the immunogenicity of two doses of mRNA vaccines in solid cancer patients with or without a previous exposure to the virus. This is a single-institution, prospective, nonrandomized study. Patients in active treatment and a control cohort of healthy people received two doses of BNT162b2 (Comirnaty, BioNTech/Pfizer, The United States) or mRNA-1273 (Spikevax, Moderna). Vaccine was administered before starting anticancer therapy or on the first day of the treatment cycle. SARS-CoV-2 antibody levels against S1, RBD (to evaluate vaccine response) and N proteins (to evaluate previous infection) were measured in plasma before the first dose and 30 days after the second one. From January to June 2021, 195 consecutive cancer patients and 20 healthy controls were enrolled. Thirty-one cancer patients had a previous exposure to SARS-CoV-2. Cancer patients previously exposed to the virus had significantly higher median levels of anti-S1 and anti-RBD IgG, compared to healthy controls (P = .0349) and to cancer patients without a previous infection (P < .001). Vaccine type (anti-S1: P < .0001; anti-RBD: P = .0045), comorbidities (anti-S1: P = .0274; anti-RBD: P = .0048) and the use of G-CSF (anti-S1: P = .0151) negatively affected the antibody response. Conversely, previous exposure to SARS-CoV-2 significantly enhanced the response to vaccination (anti-S1: P < .0001; anti-RBD: P = .0026). Vaccine immunogenicity in cancer patients with a previous exposure to SARS-CoV-2 seems comparable to that of healthy subjects. On the other hand, clinical variables of immune frailty negatively affect humoral immune response to vaccination.     

Emerging issue of fluconazole-resistant candidemia in a tertiary care hospital of southern italy: time for antifungal stewardship program

An increased number of patients is at risk of Candida spp. bloodstream infection (CBSI) in modern medicine. Moreover, the rising of antifungal resistance (AR) was recently reported. All consecutive CBSI occurred in our Hospital (consisting of 1,370 beds) between 2015 and 2018, were reviewed. For each case, Candida species, AR pattern, ward involved and demographic data of patients were recorded. Overall, 304 episodes of CBSI occurred, with a median (q1:first-,q3:third quartile) of 77 (71-82) CBSI/year. Over the years, a significant increase of CBSI due to C. albicans compared to non-albicans strains was recorded in medical wards (from 65% to 71%, p=0.030), while this ratio remained stable in others. An increase of resistant strains to multiple antifungals such as C. guillermondii was noticed in recent years (from 0% to 9.8%, p=0.008). Additionally, from 2015 to 2018 an increase in fluconazole-resistance was recorded in our Hospital (from 7.4% to 17.4%, p=0.025) and a slight increase in voriconazole-resistance (from 0% to 7% in 2018, p=0.161) was observed, while resistance to echinocandin and amphotericin B remained firmly below 2%.This study suggests a rapid spread of antifungal resistance in our Hospital; therefore, an appropriate antifungal stewardship programs is urgently warranted.

Plasma miRNA-based signatures in CRC screening programs

Colorectal cancer (CRC) screening programs help diagnose cancer precursors and early cancers and help reduce CRC mortality. However, currently recommended tests, the fecal immunochemical test (FIT) and colonoscopy, have low uptake. There is therefore a pressing need for screening strategies that are minimally invasive and consequently more acceptable to patients, most likely blood based, to increase early CRC identification. MicroRNAs (miRNAs) released from cancer cells are detectable in plasma in a remarkably stable form, making them ideal cancer biomarkers. Using plasma samples from FIT-positive (FIT+) subjects in an Italian CRC screening program, we aimed to identify plasma circulating miRNAs that detect early CRC. miRNAs were initially investigated by quantitative real-time PCR in plasma from 60 FIT+ subjects undergoing colonoscopy at Fondazione IRCCS Istituto Nazionale dei Tumori, then tested on an internal validation cohort (IVC, 201 cases) and finally in a large multicenter prospective series (external validation cohort [EVC], 1121 cases). For each endoscopic lesion (low-grade adenoma [LgA], high-grade adenoma [HgA], cancer lesion [CL]), specific signatures were identified in the IVC and confirmed on the EVC. A two-miRNA-based signature for CL and six-miRNA signatures for LgA and HgA were selected. In a multivariate analysis including sex and age at blood collection, the areas under the receiver operating characteristic curve (95% confidence interval) of the signatures were 0.644 (0.607–0.682), 0.670 (0.626–0.714) and 0.682 (0.580–0.785) for LgA, HgA and CL, respectively. A miRNA-based test could be introduced into the FIT+ workflow of CRC screening programs so as to schedule colonoscopies only for subjects likely to benefit most.     

从气机升降探讨胃癌的病机治则

胃癌是因外邪侵袭、情志内伤、饮食失调等,致气机升降失调,气血津液运化失常,气滞、血瘀、痰浊及癌毒内生,日久积聚于胃脘而成。脾胃为气机升降之枢纽,脾不升清,胃不降浊,则精微不能濡养,浊液不能排出,影响体内正常气机升降。肝主疏泄,调节全身气机的条达,肝之疏泄功能失常,气机升降失调,则影响气血运行。气机升降关系在胃癌形成中起关键作用,气机升降失调,气血津液不能正常输布运行,则气凝血滞,痰浊内停,甚则癌毒内生,发为癌瘤。故在临床治疗中注重恢复脾胃的升降功能,辛开苦降,调畅气机,恢复脾胃的正常升降功能,为胃癌的治疗提供临床指导。     

Risk behaviors among Italian healthcare students: a cross-sectional study for health promotion of future healthcare workers

Background:Risk behaviors are frequent among young adults and they are particularly relevant when considering healthcare students.Objectives:The study is aimed to examine the prevalence of smoking, binge drinking, physical inactivity, and excessive bodyweight in a population of healthcare students attending an Italian university.Methods:Healthcare students filled an anonymous multiple-choice questionnaire on the occasion of the occupational health visit that preceded their hospital internship. The questionnaire covered socio-demographic characteristics (including student’s working status and cohabitation) and risk behaviors. We evaluated the prevalence of risk behaviors and their association with socio-demographic characteristics.Results:The sample consisted of 494 students (65% women): 23.2% were smokers, 7.9% had excessive bodyweight, 35% did not practice any physical activity and 50% reported binge drinking at least once in the last 12 months. We found associations of male sex (30.5%) and being nursing students (29.9%) with smoking habit. The frequency of binge drinking was higher in men (38.4%), working students (53.9%), and among those who lived without family (50%). Physical inactivity was associated with female sex (44.2%) and living without family (57.1%). Finally, the co-presence of 2 risk behaviors or more was higher in men (36.8%), in nursing students (39.6%) and in working students (44.7%).Conclusions:Our findings regarding the prevalence of risk behaviors and their potential association with socio-demographic factors may be a clue to the definition of targeted strategies aimed at reducing of risk behaviors among healthcare students.Key words: risk behaviors, healthcare students, smoking, binge drinking, physical inactivity
