Quality of decision aids developed for women at average risk of breast cancer eligible for mammographic screening: Systematic review and assessment according to the International Patient Decision Aid Standards instrument

Mammographic screening contributes to a reduction in specific mortality, but it has disadvantages. Decision aids are tools designed to support people's decisions. Because these aids influence patient choice, their quality is crucial. The objective of the current study was to conduct a systematic review of decision aids developed for women eligible for mammographic screening who have an average breast cancer risk and to assess the quality of these aids. The systematic review included articles published between January 1, 1997, and August 1, 2019, in the PubMed, Embase, Cochrane, and PsycInfo databases. The studies were reviewed independently by 2 reviewers. Any study containing a decision aid for women eligible for mammographic screening with an average breast cancer risk was included. Two double-blind reviewers assessed the quality of the selected decision aids using the International Patient Decision Aid Standards instrument, version 3 (IPDASi). Twenty-three decision aids were extracted. Classification of decision aid quality using the IPDASi demonstrated large variations among the decision aids (maximum IPDASi score, 188; mean ± SD score, 132.6 ± 23.8; range, 85-172). Three decision aids had high overall scores. The 3 best-rated dimensions were disclosure (maximum score, 8; mean score, 6.8), focusing on transparency; information (maximum score, 32; mean score, 26.1), focusing on the provision of sufficient details; and probabilities (maximum score, 32; mean score 25), focusing on the presentation of probabilities. The 3 lowest-rated dimensions were decision support technology evaluation (maximum score, 8; mean score, 4.3), focusing on the effectiveness of the decision aid; development (maximum score, 24; mean score, 12.6), evaluating the development process; and plain language (maximum score, 4; mean score, 1.9), assessing appropriateness for patients with low literacy. The results of this review identified 3 high-quality decision aids for breast cancer screening.     

Family history of cancer and subsequent risk of cancer: A large-scale population-based prospective study in Japan

Family history (FH) of cancer is an important factor of increased risk of several cancers. Although the association between FH of cancer and concordant cancer risk has been reported in many previous epidemiological studies, no comprehensive prospective study with adjustment for lifestyle habits has evaluated the association of FH of cancer and concordant cancer risk. We investigated the association between FH of cancer and concordant cancer risk in a Japanese population-based prospective study, initiated in 1990 for cohort I and in 1993 for cohort II. We analyzed data on 103,707 eligible subjects without a history of cancer who responded to a self-administered questionnaire including FH of cancer at baseline. Study subjects were followed through 2012 and analyzed using multivariable-adjusted Cox proportional hazards regression models. During 1,802,581 person-years of follow-up, a total of 16,336 newly diagnosed cancers were identified. Any site (Hazard ratios = 1.11 (95% confidence interval = 1.07–1.15]), esophagus (2.11 [1.00–4.45]), stomach (1.36 [1.19–1.55]), liver (1.69 [1.10–2.61]), pancreas (2.63 [1.45–4.79]), lung (1.51 [1.14–2.00]), uterus (1.93 [1.06–3.51]) and bladder cancers (6.06 [2.49–14.74]) with FH of the concordant cancer were associated with an increased risk compared to those without FH. Our findings suggest that having FH of cancer is associated with an increased risk of several concordant cancer incidences in an Asian population. Enquiring about FH of several types of cancer may be important in identifying groups at high-risk of those cancers.     

中国5~18岁人群遗尿症患病率的横断面调查

目的 了解中国儿童和青少年遗尿症的患病情况。方法 横断面调查，以中国医师协会肾脏专委会中国儿童遗尿疾病管理协作组（简称：协作组）成员与所在省、自治区和直辖市有工作联系的区县为抽样单位。遗尿症诊断标准为年龄≥5岁，3个月内出现尿床事件≥1次；尿床指夜间睡眠中排尿于床上或尿湿衣裤。调查时间为2017年4月20日至2017年5月12日；调查人群为中国5~18岁儿童及青少年，分为幼儿园（5~6岁）、小学（~12岁），初中（~15岁）和高中（~18岁）。每个区县样本量需＞3 073人。自行设计遗尿症调查问卷，本文主要分析基本人口学信息和尿床事件。由儿童或青少年的家长或照护者在手机或其他安装有微信应用终端设备上填写问卷。结果 24个协作组成员所在省、自治区和直辖市中的34个区县中的225所幼儿园和学校参与了调查，其中幼儿园82所，小学61所，初中49所，高中33所。调查目标样本人群129 952人，进入本文分析的调查问卷100 071份（77.0%）。男52 074份，平均年龄（11.0±3.4）岁，汉族占92.5%，幼儿园、小学、初中、高中人数比例约为1∶5∶2∶1。中国儿童和青少年遗尿症患病率为4.8%（4 821/100 071）；幼儿园、小学、初中、高中遗尿患病率分别为12.1%、5.1%、1.1%和1.4%；各年龄男孩遗尿症患病率均高于同年龄的女孩；中国境内6大行政区（华北、东北、华东、中南、西南、西北）以样本人群年龄构成比进行标准化后，其患病率分别为4.2%，3.7%、4.6%、5.8%、5.1%和4.9%；4 821名遗尿症患儿中，轻、中、重度遗尿症患儿分别占81.4%、13.5%和5.1%；重度遗尿症幼儿园、小学、初中和高中组比例为6.9%、3.7%、5.3%和10.0%。结论 中国幼儿园、小学、初中、高中人群遗尿患病率分别为12.1%、5.1%、1.1%和1.4%，儿童遗尿症患病率总体为4.8%。幼儿园及高中组重度遗尿症的比例较高。
