TOPSIS法和秩和比法模糊联合在基本公共卫生服务质量综合评价中的应用研究

背景国家基本公共卫生服务项目的开展是我国新医改的重要举措，自2009年国家基本公共卫生服务项目开展后，其服务经费与服务项目不断扩增，由于涉及指标较多，覆盖面较广，探寻科学、客观、全面的基本公共卫生服务综合评价方法十分必要。目的探索适宜的基本公共卫生服务质量综合评价方法，通过质量评价为调整相关政策和提高服务质量提供依据。方法2019年2—4月，采用多阶段立意抽样方式从Z省南部、中部和北部地区共选取24家社区卫生服务中心（乡镇卫生院）作为评价对象，记为机构A~X。采用逼近理想解排序法（TOPSIS法）、秩和比法及二者模糊联合的方法对24家社区卫生服务中心（乡镇卫生院）2018年基层医疗卫生机构基本公共卫生服务质量进行综合评价（参考2018年国家基本公共卫生服务项目选取12项评价指标）。结果在TOPSIS法评价中，Ci值排名前三名的为A（0.917 4）、C（0.875 9）和G（0.787 9），Ci值排名后三名的为I（0.414 2）、W（0.413 7）和N（0.407 7）。在秩和比法评价中，RSR值排名前三名的为A（0.890 6）、G（0.765 6）和C（0.711 8），RSR值排名后三名的为V（0.381 9）、W（0.362 8）和K（0.357 6）。根据模糊集理论，将W1Ci+W2RSR值进行排序，依据"择多原则"，排名前三名的分别为A、C和G，排名后三名的分别为I、K和W，这与TOPSIS法和秩和比法的评价结果基本一致。结论TOPSIS法和秩和比法模糊联合得到的评价结果及影响因素与其他研究结果相一致，并且两者联用能克服单一使用TOPSIS法或秩和比法的局限性，适宜在基本公共卫生服务质量评价中推广应用。     

TIC en actividad física y parámetros cardiovasculares en mayores: una revisión

IntroductionAgeing is a period of physical and psychological changes. Inactivity is one of the biggest problems among the older adult population increasing the risk of sarcopenia and chronic diseases. Physical activity is an effective intervention to improve health outcomes. In recent years, there has been an increase in the use of technology, with health technology tools (ICT) appearing as an intervention to increase physical activity and improve associated health problems.ObjectiveIn this review, we evaluated the effectiveness of health technology to increase physical activity and to improve cardiovascular parameters in older adults.MethodologyStudies with a great variety of health technology tools to increase physical activity levels, and that evaluated the effect of that increase on cardiovascular parameters were included by searching the main databases.ResultsEleven studies reporting the use of a variety of ICT tools were included in this review. Despite these differences, the effectiveness of health technology tool interventions has been demonstrated in increasing physical activity and reducing cardiovascular parameters.DiscussionThe lack of adherence of older adults to health technology would be a disadvantage, but it has been shown that younger older adults are more familiar with health technology tools and the number using them is increasing.ConclusionHealth technology tools show effectiveness in increasing physical activity in older adults and improving cardiovascular parameters.

肝内胆管癌术前评估要点

肝内胆管癌（ICC）是发病率仅次于肝细胞癌的原发性肝癌，其恶性程度高，预后差。近年来，ICC的发病率逐步上升。根治性手术切除是目前可能使病人获得长期生存最有效的治疗方式，但根治性切除率低、术后复发率高仍是外科医生和ICC病人共同面临的巨大阻碍。然而由于ICC发病隐匿和恶性程度高的特性使很多病人初诊时便丧失了手术治疗的机会。因此，早期筛查、准确临床诊断、充分术前评估及完备精准的手术方案是手术赖以顺利实施的保障。癌胚抗原（CEA）和CA19-9对ICC的诊断具有一定价值。影像学检查是诊断ICC的最重要手段。腹部超声是临床第一线的早期筛查手段；CT和MRI是临床上用于ICC最常用的影像学检查。三维重建技术为术前残肝体积预估，手术方案制定提供更直接更精准的信息。建立能准确预测ICC预后的分期系统非常重要。术前减黄是否需要尚存争议。残肝体积和肿瘤是否转移是判断手术可切除性的两个要点。腹腔镜探查、腹腔镜超声检查及术中快速冷冻活检是判断是否可实施根治性切除的重要手段。     

Rare patients in routine care: Treatment and outcome in advanced papillary renal cell carcinoma in the prospective German clinical RCC-Registry

Non-clear cell renal cell carcinoma is a very rare malignancy that includes several histological subtypes. Each subtype may need to be addressed separately regarding prognosis and treatment; however, no Phase III clinical trial data exist. Thus, treatment recommendations for patients with non-clear cell metastatic RCC (mRCC) remain unclear. We present first prospective data on choice of first- and second-line treatment in routine practice and outcome of patients with papillary mRCC. From the prospective German clinical cohort study (RCC-Registry), 99 patients with papillary mRCC treated with systemic first-line therapy between December 2007 and May 2017 were included. Prospectively enrolled patients who had started first-line treatment until May 15, 2016, were included into the outcome analyses (n = 82). Treatment was similar to therapies used for clear cell mRCC and consisted of tyrosine kinase inhibitors, mechanistic target of rapamycin inhibitors and recently checkpoint inhibitors. Median progression-free survival from start of first-line treatment was 5.4 months (95% confidence interval [CI], 4.1–9.2) and median overall survival was 12.0 months (95% CI, 8.1–20.0). At data cutoff, 73% of the patients died, 6% were still observed, 12% were lost to follow-up, and 9% were alive at the end of the individual 3-year observation period. Despite the lack of prospective Phase III evidence in patients with papillary mRCC, our real-world data reveal effectiveness of systemic clear cell mRCC therapy in papillary mRCC. The prognosis seems to be inferior for papillary compared to clear cell mRCC. Further studies are needed to identify drivers of effectiveness of systemic therapy for papillary mRCC.

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.
