Glaucoma is disease of the optic nerve, which, if left untreated, can lead to irreversible loss of vision. Over the past few decades there have been significant advances in both the medical and surgical treatment of glaucoma. Today, with early diagnosis and treatment, most patients with glaucoma can be well controlled and avoid significant loss of vision from glaucoma. Since glaucoma is a common ophthalmologic disease, with high prevalence in the elderly, it is important to understand the various treatment options. The purpose of this review is to discuss the management and treatment of primary open-angle glaucoma (medical management and surgical options) and review the key studies that aid physicians in the management of this disease.
青光眼是一种视神经疾病,如果不及时治疗,可能会导致不可逆转的视力丧失。在过去的几十年里,青光眼的内科和外科治疗都取得了重大进展。今天,通过早期诊断和治疗,大多数青光眼患者可以得到很好的控制,避免青光眼导致的严重视力丧失。由于青光眼是一种常见的眼科疾病,在老年人中发病率很高,了解各种治疗方案是很重要的。本综述的目的是讨论原发性开角型青光眼的管理和治疗(医疗管理和手术选择),并回顾有助于医生管理这种疾病的关键研究。

Evaluation of: Richards JB, Papaioannou A, Adachi JD et al.: Effect of selective serotonin reuptake inhibitors on the risk of fracture. Arch. Intern. Med. 167, 188–194 (2007) [1]. The results of a cohort study of 5008 community-dwelling subjects aged over 50 years was presented. Among these, 137 were daily users of selective serotonin-reuptake inhibitors. The study reported an increased risk of fragility fractures (fractures occurring after minimal trauma; hazard ratio: 2.1; 95% confidence interval: 1.3–3.4) and an increased risk of falls (hazard ratio: 2.2; 95% confidence interval: 1.4–3.5) among daily users of selective serotonin-reuptake inhibitors. Bone mineral density was lower in the hip in daily selective serotonin-reuptake inhibitors users and there was a trend towards lower bone mineral density in the spine. A dose–response relationship was present.

Chronic illness is the predominant disease pattern today; however, healthcare systems have been slow to adapt. This paper describes a number of strategies to enhance chronic illness care, now often termed ‘care for long-term conditions’, including targeting, prior authorization, guidelines, profiling, financial incentives, gatekeeping, subcapitation, case management, information systems, interdisciplinary teams and end-of-life care. It compares how such programs have been implemented in the UK, under the NHS framework, and in the USA.
慢性病是当今主要的疾病模式;然而,医疗保健系统的适应速度很慢。本文描述了一些加强慢性病护理的策略,现在通常被称为“长期护理”,包括目标、事先授权、指导方针、分析、财务激励、把关、分额、病例管理、信息系统、跨学科团队和临终关怀。它比较了这些项目在英国、NHS框架下和美国的实施情况。

This review addresses the impact of Type 2 diabetes mellitus on the brain. We show that there is convincing evidence that Type 2 diabetes mellitus is associated with accelerated cognitive decline and dementia. The structural basis for these cognitive deficits includes both vascular lesions and global cerebral atrophy. Cerebral changes may already develop in prediabetes mellitus stages. Several areas of uncertainty need to be resolved in order to develop effective preventive strategies. Information on the risk factors for accelerated cognitive decline in patients with Type 2 diabetes mellitus is still scarce. Identification of these factors might help to identify individuals who are at risk for clinically relevant impairments and to develop specific interventions. Further studies on the course of development of cognitive decline in Type 2 diabetes mellitus may help to decide at what stage these interventions should be initiated.
本文综述了2型糖尿病对大脑的影响。我们表明,有令人信服的证据表明,2型糖尿病与加速认知能力下降和痴呆有关。这些认知缺陷的结构基础包括血管病变和整体脑萎缩。大脑的变化可能在糖尿病前期就已经发生了。需要解决几个不确定的领域,以便制定有效的预防战略。关于2型糖尿病患者认知能力加速下降的危险因素的信息仍然很少。识别这些因素可能有助于识别有临床相关损伤风险的个体,并制定具体的干预措施。对2型糖尿病认知能力下降发展过程的进一步研究可能有助于决定在什么阶段开始这些干预措施。

Age-related macular degeneration causes blindness in elderly individuals. In the last decade, the search for mechanisms that initiate and sustain neovascularization in age-related macular degeneration has focused on the actions of vascular endothelial growth factor. The first approved drug that inhibited vascular endothelial growth factor for the treatment of neovascular age-related macular degeneration was pegaptanib sodium. This pegylated RNA aptamer has shown efficacy in two pivotal Phase III trials for the treatment of neovascular age-related macular degeneration. Pegaptanib therefore has the notable distinction of being the only aptamer therapeutic approved for use in humans, possibly paving the road for future aptamer applications.
年龄相关性黄斑变性会导致老年人失明。在过去的十年中,对年龄相关性黄斑变性中启动和维持新生血管形成机制的研究主要集中在血管内皮生长因子的作用上。首个被批准用于治疗新生血管性年龄相关性黄斑变性的抑制血管内皮生长因子的药物是佩加他尼钠。这种聚乙二醇化RNA适配体在两项关键的III期试验中显示出治疗新生血管性年龄相关性黄斑变性的疗效。因此,Pegaptanib是唯一被批准用于人类的适体治疗药物,可能为未来的适体应用铺平道路。

Sildenafil in the treatment of erectile dysfunction 西地那非治疗勃起功能障碍
Pub Date : 2007-06-11 DOI: 10.2217/1745509X.3.3.295

Erectile dysfunction affects more than 150 million men worldwide and is increasingly prevalent. Elderly men are at increased risk for erectile dysfunction, which is, in part, owing to medical comorbidities associated with erectile dysfunction. Sildenafil, the first US FDA-approved, oral phosphodiesterase type-5 inhibitor, has revolutionized the treatment of erectile dysfunction since its approval in 1998. High treatment success rates and low number of adverse events, in addition to significant improvements in psychosocial parameters, have resulted in increased patient and physician satisfaction with sildenafil, and increased usage. Safety has been demonstrated in patients with stable cardiovascular disease, and rates of discontinuation owing to adverse effects remains low.
勃起功能障碍影响着全球超过1.5亿男性,并且越来越普遍。老年男性患勃起功能障碍的风险增加,部分原因是与勃起功能障碍相关的医学合并症。西地那非是美国fda批准的第一个口服磷酸二酯酶5型抑制剂,自1998年批准以来,它已经彻底改变了勃起功能障碍的治疗。高治疗成功率和低不良事件数量,加上心理社会参数的显著改善,导致患者和医生对西地那非的满意度提高,并增加了使用量。稳定性心血管疾病患者的安全性已得到证实,因不良反应而停药的比率仍然很低。

Every other year, Abraham Fisher of the Israel Institute for Biological Research in Ness-Ziona (Israel) and Israel Hanin of Loyola University, Maywood (IL, USA), join forces with two European scientists to host a conference on two of our most common neurodegenerative diseases: Alzheimer’s disease (AD) and Parkinson’s disease (PD). This year, the meeting was held in Salzburg, Austria, and the local hosts were Werner Poewe, who chairs the department of neurology at the Medical University of Innsbruck (Austria), and Manfred Windisch, who heads the Austrian research organization JSW-Research Ltd in Graz (Austria). The program attracted 2150 participants from 59 different countries, which is a record in the history of the AD/PD meetings. A distinctive goal of the AD/PD meetings is to provide a forum for the presentation of results focused on AD and PD individually, while also covering the latest developments regarding the commonalities between neurodegenerative diseases in general. The reason for the latter focus is becoming more and more apparent. AD and PD share certain clinical, pathological and biochemical features. Both are prevalent, age-related neurodegenerative diseases that are characterized by premature neuronal death and protein aggregation caused by genetic and environmental factors in a complex interaction, and both pose an enormous threat to public health resources, especially in the light of the increased life expectancy worldwide. The currently available treatments for AD and PD are focused on replacing the neurotransmitter that is missing: acetylcholine in AD and dopamine in PD. In both diseases, however, substantial efforts have been made to translate the advances on understanding the molecular pathogenesis, especially the importance of protein aggregation, into therapeutic strategies. This conference report provides an overview of the major recent developments in the complex spectrum of AD, PD and some other related disorders as reflected in the meeting.
每隔一年,以色列尼斯-锡奥纳生物研究所的亚伯拉罕·费舍尔和美国伊利诺斯州梅伍德洛约拉大学的以色列·哈宁就两种最常见的神经退行性疾病——阿尔茨海默病(AD)和帕金森氏病(PD)——与两位欧洲科学家联合举办一次会议。今年,会议在奥地利的萨尔茨堡举行,当地的主持人是因斯布鲁克医科大学(奥地利)神经内科主任Werner Poewe和奥地利格拉茨研究机构JSW-Research Ltd的负责人Manfred Windisch。此次会议吸引了来自59个国家的2150名与会者,创下了AD/PD会议的历史记录。AD/PD会议的一个独特目标是提供一个论坛,介绍单独关注AD和PD的结果,同时也涵盖有关一般神经退行性疾病之间共性的最新发展。后一种关注点的原因越来越明显。AD和PD具有一定的临床、病理和生化特征。两者都是普遍存在的与年龄有关的神经退行性疾病,其特征是遗传和环境因素在复杂的相互作用中引起的神经细胞过早死亡和蛋白质聚集,两者都对公共卫生资源构成巨大威胁,特别是考虑到全球预期寿命的增加。目前,阿尔茨海默病和帕金森病的治疗主要集中在替代缺失的神经递质:阿尔茨海默病中的乙酰胆碱和帕金森病中的多巴胺。然而,在这两种疾病中,已经做出了大量的努力,将对分子发病机制的理解的进展,特别是蛋白质聚集的重要性,转化为治疗策略。本会议报告概述了会议反映的阿尔茨海默病、帕金森病和其他一些相关疾病的复杂谱系的主要最新发展。

This conference report provides an overview of the major recent developments in the complex spectrum of AD, PD and some other related disorders as reflected in the meeting.","PeriodicalId":88353,"journal":{"name":"Aging health","volume":"3 1","pages":"305-307"},"PeriodicalIF":0.0,"publicationDate":"2007-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2217/1745509X.3.3.305","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68187264","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Is chemotherapy underutilized in the elderly? Yes, most probably. Back in 1990, a group of pioneers in the field of geriatric oncology published a provocative editorial entitled ‘Why are elderly cancer patients badly treated?’ [1]. Eminent members of the same group recently concluded their scientific review on the treatment of cancer in older patients by writing: “Although we are on the right track, there is still a long way to go” [2]. Answers have thus been provided in the interval between these two communications but many questions still remain. There have been remarkable societal changes in the 20th century and the unexpected lengthening of life-expectancy has been one of the most crucial. Previously, the third and the fourth age were the privilege of few lucky individuals, capable of escaping from misery, epidemics and catastrophes. Today, the vast majority of us may expect to get old and to live these years in very good health. However, parallel to the aging of the population, cancer disorders have increased in number and over half are now diagnosed in the eight, ninth and tenth decades of life. If the incidence of cancer is 207/100,000 below 65 years of age, it rises to 2261/100,000 above that age, that is, 11-fold higher [3]. In other words, cancer has now become a disease of the elderly. It is predicted that 15 million new cases of cancer will be diagnosed worldwide in the year 2020 in comparison with 10 million 20 years before [4]. And the evidence is that the majority will concern people over the age of 70 years, the senior adults. These numbers demand serious analysis. What we have learned over the past years should be used to prepare for the future in the full respect of the ethics of our societies. To find the balance between autonomy, beneficence and justice is a major challenge. Despite scientific advances in the
化疗在老年人中利用不足吗?是的,很有可能。早在1990年,一群老年肿瘤学领域的先驱发表了一篇题为《为什么老年癌症患者得不到善待?》”[1]。该组织的知名成员最近总结了他们对老年癌症治疗的科学评论,他们写道:“尽管我们走在正确的道路上,但仍有很长的路要走。”因此,在这两次通信之间的时间间隔提供了答案,但仍然存在许多问题。20世纪发生了显著的社会变化,预期寿命的意外延长是其中最重要的变化之一。以前,第三和第四个时代是少数幸运儿的特权,他们能够摆脱苦难、流行病和灾难。今天,我们中的绝大多数人可能会期望变老,并在这些年中健康地生活。然而,在人口老龄化的同时,癌症疾病的数量也在增加,现在有一半以上的人是在生命的第八、第九和第十个十年被诊断出来的。如果65岁以下的癌症发病率为207/10万,那么65岁以上的癌症发病率上升到2261/10万,即高出11倍。换句话说,癌症现在已经成为老年人的疾病。据预测,到2020年,全球将诊断出1500万例新的癌症病例,而在2020年之前的20年,这一数字为1000万。有证据表明,大多数人会关注70岁以上的老年人。这些数字需要认真分析。我们应该在充分尊重我们社会的道德规范的情况下,利用过去几年所学到的东西为未来做准备。如何在自治、慈善和正义之间找到平衡是一项重大挑战。尽管科学进步
