Efficient Denoising Framework for Mammogram Images with a New Impulse Detector and Non-Local Means

Objective: The survival rates of breast cancer are increasing as screening and diagnosis improve. The removal of noise is revealed to be a significant step for automatic - computer aided detection (CAD) of microcalcification in digital mammography. Methods: In this paper, a combined approach for eradicating impulse noise from digital mammograms is proposed. The process is achieved in two stages, detection of noise followed by filtering of noise. The detection of noise is carried out by using Modified Robust Outlyingness Ratio (mROR) trailed by an extended NL (Non-Local)-means filter for filtering mechanism. Results: According to the value of mROR, all pixels in mammogram images are divided into four distinct groups. In each cluster, many decision rules are then applied for detecting the impulse noise. Filtering is done with NL-means filter by providing a reference mammogram image. Conclusion: The comparative analysis and evaluated results are compared with some existing filters which indicate that the proposed structure outperforms the analysed result of others.     

A conceptual model and detailed framework for stress-related,strain-related,and overuse athletic injury

A multitude of athletic injuries occur when the various tissues that make up the human body experience stresses and strains that exceed their material strength. The precise amount of stress and strain that any given tissue can withstand is determined by the mechanical properties and resultant strength of that particular tissue. These mechanical properties are directly determined by an individual’s physiology and acute regulation of these properties. A number of theoretical frameworks for athletic injury occurrence have been proposed, however, a detailed conceptual framework for injury aetiology that considers the interplay between the physiological and mechanical factors and outlines the causal pathways to tissue damage and injury is needed. This will guide injury research towards a more thorough investigation of causal mechanisms and understanding of risk factors. Further, it is important to take into account the considerable differences in loading patterns which can result in varying injury outcomes such as acute stress-related, strain-related, or overuse injury. Within this article a simplified conceptual model of athletic injury is proposed along with a detailed, evidence-informed, conceptual framework for athletic injury aetiology that focuses on stress-related, strain-related, and overuse injury.     

Developing an Educational Framework for Urological Nursing: Using a World Café approach to gain an emerging international understanding of issues,challenges and responses

A series of three World Café events centred on the topic of developing an Educational Framework for Urological Nursing [EFUN] were held by the British Association of Urological Nurses [BAUN], the European Association of Urology Nurses [EAUN] and the Australian and New Zealand Urological Nursing Society [ANZUNS] between 2017 and 2019. About 376 urology nurses participated in these “conversations that matter” and generated 1047 individual response items that were grouped into themes to assist the three associations to take the creation of an EFUN to the next level. Areas explored centred on four aspects: what any agreed educational framework for urology nursing should contain; the academic level at which education should be provided; who should be recruited as collaborators on writing an educational framework and, lastly, just how any emergent framework should be used. Analysis of the conversational data indicate that there exists within the urological nursing community a collective wisdom regarding their educational needs and how these needs should be met.     

应用多孔高密度聚乙烯支架行儿童全耳再造术

目的总结20例儿童应用多孔高密度聚乙烯(Medpor)支架全耳再造术的经验,以利于提高此项手术效果。方法2000~2004年,应用该支架施行全耳再造术20例,其中左侧6例,右侧14例。残耳大小1 cm×1 cm~6.3 cm×2.0 cm。Ⅰ期再造11例(Medpor支架置入、颞浅筋膜瓣与残耳皮瓣转移加全厚皮片移植);Ⅱ期再造9例(其中耳后皮瓣扩张法2例,Ⅰ期残耳旷置、Medpor支架置入、颞浅筋膜瓣转移加全厚皮片移植,Ⅱ期耳垂、耳屏成形7例)。结果Ⅰ期愈合17例,延迟愈合3例,Ⅱ期修复5例,取出支架1例。20例中19例获随访,随访时间3月至3年。再造耳大小5.3 cm×3.2 cm~7.2 cm×5.2 cm,与健耳无明显差别;再造耳解剖轮廓显现较好,但质地稍偏硬,耳屏或耳垂需不同程度的修整。结论应用Medpor支架具有以下主要优点:⑴不造成其他部位的创伤;⑵手术时间缩短;⑶支架可与局部组织融合并稳妥固定;⑷支架无变形或吸收,组织排斥现象较少;⑸术后及随访显示,再造耳轮廓较为清晰、美观。该支架仍是目前儿童行全耳再造术较适宜的人工支架材料。     

Is the apparent U-shape of well-being over the life course a result of inappropriate use of control variables? A commentary on Blanchflower and Oswald (66: 8, 2008, 1733–1749)

In their article in this journal “Is well-being U-shaped over the life cycle?” Blanchflower and Oswald (Blanchflower, D.G., & Oswald, A.J. (2008). Is well-being U-shaped over the life cycle? Social Science & Medicine, 66, 1733–1749) report the results of an ambitious cross-national study of age and well-being and conclude that in most societies studied the well-being of adults tends to be high in young adulthood and old age and lowest around age 40. I argue that the appearance of this U-shaped curve of well-being is the result of the use of inappropriate and questionable control variables. The most clearly inappropriate control variable is marital status, the control of which to a large extent accounts for the U-shaped curve. Most researchers who have studied the relationship between being married and being happy believe that happiness affects marital status (happier people are more likely to marry and stay married), and of course a variable that is affected by the dependent variable should not be included as a control variable in a simple recursive model. Such control variables as income and education are suspect because the relationship between them and well-being is likely to be partially spurious, and such variables as race and whether or not persons lived with both parents at age 16 should not be controlled, because they cannot affect or be affected by age. Finally, year of survey should not be controlled because of the age-period-cohort conundrum, which makes including age, period, and cohort all as predictor variables in a regression inappropriate (and impossible if the three variables are measured precisely and comparably). The only clearly appropriate control variable is birth cohort, and when only it is controlled, the regression data become estimates of how the well-being of persons has actually changed as they have gone through the life course. I argue that such estimates are much more useful than the counterfactual abstractions provided by Blanchflower and Oswald (Blanchflower, D.G., & Oswald, A.J. (2008). Is well-being U-shaped over the life cycle? Social Science & Medicine, 66, 1733–1749), and I conclude that those authors (or someone else) could make a very important contribution by redoing their analyses with birth cohort as the only control variable. I do that with the American happiness data and find that the results do not come close to the U-shaped pattern.     

国外经典慢性病管理模式对我国慢性病管理的启示

随着城镇化加快、生活方式变化及全球人口老龄化,慢性病带来的危害日益严重。慢性病的服务提供是卫生服务系统的难题之一,而慢性病管理模式为其创设了一个新的框架。本文主要介绍慢性病照护模式、慢性病自我管理计划和创新型慢性病照护框架3种国外经典慢性病管理模式,从特点、应用效果、局限性等方面进行比较,发现其核心要素包括多方协同、连续性服务、患者自我管理、循证决策、信息技术支持等。以上经验为我国的慢性病管理工作提供了新思路：建立政府主导、多元协同的管理制度,以家庭医生签约服务为“抓手”提高服务连续性,借力智慧医疗并强化患者赋能等,以期取得更好的慢性病管理效果。
