Endurance training may improve exercise capacity,lung function and quality of life in Fontan patients

Children born with univentricular hearts undergo staged surgical procedures to a Fontan circulation. Long-term experience with Fontan palliation has shown dramatically improved survival but also of a life-long burden of an abnormal circulation with significant morbidity. Many Fontan patients have reduced exercise capacity, oxygen uptake, lung function and quality of life. Endurance training may improve submaximal, but not maximal, exercise capacity, lung function and quality of life. Physical activity and endurance training is also positively correlated with sleep quality. Reviewing the literature and from our single-centre experience, we believe there is enough evidence to support structured individualised endurance training in most young Fontan patients.     

Accounting for Unobservable Preference Heterogeneity and Evaluating Alternative Anchoring Approaches to Estimate Country-Specific EQ-5D-Y Value Sets: A Case Study Using Spanish Preference Data

ObjectivesThe EuroQol Group published the EQ-5D-Y valuation protocol that recommends 2 valuation techniques to elicit preferences: composite time trade-off (C-TTO) and discrete choice experiments (DCEs). The protocol left the decision of what modeling approach to use open for researchers. Our aims were to explore modeling strategies allowing generation of EQ-5D-Y value sets and to produce an EQ-5D-Y Spanish value set.MethodsWe used EQ-5D-Y DCE and C-TTO data collected in Spain following the protocol and adopted a staged approach for our modeling exercise. First, we selected the best performing DCE latent class model and evaluated models from 2 to 10 classes. We selected the preferred model based on best goodness of fit in terms of the Bayesian information criterion. We considered 2 anchoring approaches to estimate utility values: (1) pits state anchoring and (2) hybrid models (using all available C-TTO responses). All analysis were weighted to be representative of the Spanish population.ResultsWe collected 1005 DCE and 200 C-TTO interviews. We selected a DCE model including 4 classes. Hybrid models using all available C-TTO observations produced a narrower range of values than the pits state anchoring approach.ConclusionsIn this article, we have presented an EQ-5D-Y value set that can be used for cost-utility analysis in Spain. The international EQ-5D-Y valuation protocol should be updated to include a different set of health states for the C-TTO experiment if researchers wish to use alternative anchoring approaches to the “pits state.”     

Minimally Invasive Treatments for Benign Prostatic Hyperplasia: Systematic Review and Network Meta-Analysis

PurposeTo review and to compare indirectly the outcomes of minimally invasive therapies for the treatment of lower urinary tract symptoms secondary to benign prostatic hyperplasia.Materials and MethodsA literature search via Medline and Cochrane Central databases was completed for randomized control studies published between January 2000 to April 2020 for the following therapies: Rezum, Urolift, Aquablation, and prostatic artery embolization (PAE). Data on the following variables were included: International prostate symptom score (IPSS), maximum urinary flow rate, quality of life, and postvoid residual (PVR). Standard mean differences between treatments were compared through a meta-analysis using transurethral resection of the prostate (TURP) to assess differences in treatment effect.ResultsThere was no significant difference in outcomes between therapies for IPSS at the 3, 6, and 12-month follow ups. Although outcomes for Rezum were only available out to 3 months, there were no consistently significant differences in outcomes when comparing Aquablation versus PAE versus Rezum. TURP PVR was significantly better than Urolift at 3, 6, and 12 months. No significant differences in minor or major adverse events were noted.ConclusionAlthough significant differences in outcomes were limited, Aquablation and PAE were the most durable at 12 months. PAE has been well studied on multiple randomized control trials with minimal adverse events while Aquablation has limited high quality data and has been associated with bleeding-related complications.

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。     

国内外不孕不育患者健康相关生命质量量表的系统综述与评价研究

背景 健康相关生命质量（HRQoL）是用于评价临床疗效的重要指标。目前，不孕不育患者HRQoL量表得到了广泛应用，但尚不确定这些量表应用于临床时是否具有良好的测量性能，缺乏对量表的质量评价。 目的 系统综述与评价不孕不育患者HRQoL量表，为合理选择健康结果测量工具提供参考。 方法 于2020年10月，计算机检索PubMed、Web of Science、the Cochrane Library、EmBase、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和中国生物医学文献数据库，获取国内外公开发表的有关不孕不育患者HRQoL的研究，检索时限均为建库至2020-10-05。由两名研究者独立筛选文献和提取资料后，采用健康测量工具遴选标准（COSMIN）对不孕不育患者HRQoL特异性量表开发研究的方法学质量，以及量表的测量性能进行评价，采用描述分析法对评价结果进行汇总、分析。 结果 共纳入229篇文献，涉及19个不孕不育患者HRQoL量表，其中4个为不孕不育患者HRQoL特异性量表〔TLMK、生育生活质量量表（FertiQoL）、QOLICQ及中医肝郁型不孕症生命质量量表〕，4个为用于测评癌症及其他疾病患者HRQoL的特异性量表，11个为普适性HRQoL量表，FertiQoL量表在现有不孕不育患者HRQoL相关研究中被使用的频次最高〔39.1%（91/233）〕。PROMs开发方面，除FertiQoL量表开发的总体质量为"有问题的"外，其余3个量表开发的总体质量均为"不合格"。内容效度方面，FertiQoL、QOLICQ量表开发研究的方法学质量分别为"非常好""有问题的"，TLMK、中医肝郁型不孕症生命质量量表开发研究的方法学质量均为"合格"。结构效度方面，除QOLICQ量表开发研究方法学质量为"有问题的"外，其余3个量表开发研究的方法学质量为"合格"；4个量表的结构效度均为"不确定"。内部一致性方面，4个量表开发研究的方法学质量均为"非常好"，4个量表的内部一致性均为"足够"。重测信度方面，QOLICQ量表开发研究的方法学质量为"有问题的"，量表的重测信度为"不确定"。效标效度方面，中医肝郁型不孕症生命质量量表开发研究的方法学质量为"非常好"，量表的效标效度为"足够"。建构效度方面，TLMK量表开发研究的方法学质量为"非常好"，量表的建构效度为"足够"。反应度/灵敏度方面，FertiQoL量表开发研究的方法学质量为"非常好"，量表的反应度/灵敏度为"足够"。 结论 现存的不孕不育患者HRQoL特异性量表中，FertiQoL量表开发研究的方法学质量及量表的测量性能相对较高。中国不孕不育患者HRQoL特异性量表研究数量相对不足，未来应开展更多的研究。     

Feasibility of a method for low contrast CT image quality assessment using difference detail curves for abdominal scans

This work describes a measurement method for assessing dose-related image-quality of CT scans based on the difference detail curve (DDC) method, and showcases its use in a low contrast setting. The method is based on a phantom consisting of elliptical slices of different sizes into which contrast object modules can be inserted. These modules contain contrast objects based on (synthetic) resin mixtures with sucrose (native) or sodium iodine (contrast medium). Mixing ratios are provided to achieve a range of clinically relevant CT-numbers with these materials. The phantom is characterized in terms of contrast accuracy, energy dependency and long-term drift with satisfying results. Contrast accuracy and energy dependency are similar to that of water or soft tissue. Image quality of 655 scans of the phantom acquired at 30 different clinical institutions and with 16 different CT scanner models from 4 manufacturers was assessed by calculating a difference detail curve (DDC) from evaluation of up to 5 human observers using a custom-made software (RadiVates) described in this work. Based on these measurements, inter-observer variability was quantified using a bootstrap method and was shown to be a large contributor to the overall variability. This work demonstrates that assessment of CT image quality is feasible with the aforementioned phantom and DDC method.
