Evaluation of: Nichol KL, Nordin JD, Nelson DB, Mullooly JP, Hak E: Effectiveness of influenza vaccine in the community-dwelling elderly. N. Engl. J. Med. 357(14), 1373–1381 (2007). Recent publications have questioned the benefit of influenza vaccination in the older adult population. To address this issue, Nichol et al. reported a study of 713,872 person-seasons over ten influenza seasons, which showed that influenza vaccination was associated with significant reductions in influenza-related hospitalizations and deaths among community-dwelling older adults. The comprehensive database ensured adequate baseline and follow-up data for annually defined influenza seasons. This analytic method reduces the potential of survivor bias when the baseline is established in the summer months preceding the influenza season, as has been used in other studies. The results were further supported by a sensitivity analysis using a hypothetical confounder to detect a healthy vaccinee bias and showed that the hospitalization...

Does ‘Hospital in the Home’ treatment prevent delirium? “家庭医院”治疗能预防谵妄吗?
Pub Date : 2008-01-31 DOI: 10.2217/1745509X.4.1.69

Delirium is a common problem, mostly affecting older patients in hospital, which results in greater mortality, nursing-home placement and cognitive and functional impairment. Delirium can be triggered by a wide range of conditions, treatments and procedures, as well as by certain environments. Some hospital environments have been causally implicated, but until it was possible to compare treatment in-hospital with treatment in other places, the observation remained at the level of an association. However, the development of ‘Hospital in the Home’ services has allowed clinicians to explore this question scientifically. Recently, a number of studies comparing treatment of acute conditions, both medical and surgical, and rehabilitation in hospital with treatment at home, have found a lower incidence of delirium with home treatment, as well as lower rates of the sequelae of delirium. Since delirium is an indicator of a wide range of subsequent poor outcomes, this information has broad implications for the deli...
谵妄是一种常见问题,主要影响住院的老年患者,导致更高的死亡率、养老院安置以及认知和功能障碍。谵妄可以由各种各样的条件、治疗和程序以及某些环境引发。一些医院的环境与此有因果关系,但在有可能将住院治疗与其他地方的治疗进行比较之前,观察结果仍停留在关联的水平上。然而,“家庭医院”服务的发展使临床医生能够科学地探索这个问题。最近,一些研究比较了急性病的内科和外科治疗,以及在医院康复与在家治疗,发现在家治疗谵妄的发生率较低,谵妄后遗症的发生率也较低。由于谵妄是一系列后续不良结果的一个指标,这一信息对熟食店有着广泛的影响。

Prolonged-release melatonin for the treatment of insomnia: targeting quality of sleep and morning alertness 延长释放褪黑素治疗失眠:针对睡眠质量和晨间警觉性
Pub Date : 2008-01-31 DOI: 10.2217/1745509X.4.1.11

Prolonged-release (PR) melatonin (Circadin ® , Neurim Pharmaceuticals, Tel-Aviv, Israel) is a nonbenzodiazepine licensed to treat primary insomnia in patients aged 55 years and older. It exerts its effects by mimicking endogenous melatonin, a hormone which regulates sleep. PR-melatonin has been shown to be effective in improving quality of sleep and morning alertness. An oral dose of 2 mg once-daily for 3 weeks has generally been well tolerated, and does not cause ‘hangover’ effects or impair memory and psychomotor skills. Insomnia is a common sleep disorder, the diagnosis of which is based on a patient’s complaint of difficulty in initiating or maintaining sleep and/or sleep that is of inadequate quality (nonrestorative sleep). The sleep disturbance should have been present for at least 1 month and be associated with a negative impact on functioning the following day [1,2]. Insomnia occurs in 30–45% of adults [3,4] and is 1.5-times more likely in women than in men [5,6]. The prevalence of insomnia increases with age [7,8]. Insomnia may be secondary – particularly when associated with mental disorders or pain – or primary, that is not attributable to any physical or mental disorder or to any environmental cause. There are widely varying reports of the prevalence of primary insomnia in the general population from 1–10% and ranging up to 25% in the elderly [9,10]. Sleep disorders, including primary insomnia, place a tremendous burden on society due to their association with psychiatric disorders, their negative impact on quality of life, their association with falls and road traffic accidents and the reduced productivity and increased utilization of healthcare services by sufferers [10–16]. There is a poor correlation between the clinical complaints associated with insomnia and the findings at polysomnography that frequently fail to demonstrate any sleep-quality related cause for the problem [17–20]. However, the tenth revision of the International Classification of Diseases (ICD 10) acknowledges that ‘there are people who suffer immensely from the poor quality of their sleep, while sleep in quantity is judged subjectively, and/or objectively as within the normal limits’ [2]. Sleep quality is thus an important parameter of the clinical complaint of insomnia, with the diagnosis and the evaluation of treatment effects based solely on subjective assessments.
缓释(PR)褪黑激素(Circadin®,Neurim Pharmaceuticals, Tel-Aviv, Israel)是一种非苯二氮卓类药物,被许可用于治疗55岁及以上患者的原发性失眠。它通过模仿内源性褪黑激素(一种调节睡眠的激素)来发挥作用。pr -褪黑素已被证明能有效改善睡眠质量和提高晨间警觉性。口服2mg,每日一次,持续3周,通常耐受性良好,不会引起“宿醉”效应或损害记忆和精神运动技能。失眠是一种常见的睡眠障碍,其诊断是基于患者对难以开始或维持睡眠和/或睡眠质量不足(非恢复性睡眠)的主诉。睡眠障碍应存在至少1个月,并与次日功能的负面影响相关[1,2]。30-45%的成年人有失眠症[3,4],女性的失眠症发生率是男性的1.5倍[5,6]。失眠的患病率随着年龄的增长而增加[7,8]。失眠可能是继发性的——特别是当伴有精神障碍或疼痛时——也可能是原发性的,不能归因于任何身体或精神障碍或任何环境原因。关于原发性失眠症在普通人群中的患病率为1-10%,在老年人中高达25%的报道各不相同[9,10]。睡眠障碍,包括原发性失眠,由于与精神疾病的关联、对生活质量的负面影响、与跌倒和道路交通事故的关联以及患者生产力的降低和对医疗保健服务的利用的增加,给社会带来了巨大的负担[10-16]。与失眠相关的临床主诉与多导睡眠图的发现之间的相关性很差,多导睡眠图常常不能证明失眠与睡眠质量有关的任何原因[17-20]。然而,第十版《国际疾病分类》(ICD 10)承认,“有些人的睡眠质量非常差,而睡眠的数量是主观上判断的,和/或客观上是在正常范围内”。因此,睡眠质量是失眠临床主诉的一个重要参数,其诊断和治疗效果的评价完全基于主观评价。

There is growing evidence for the association of antiepileptic medications (AEDs) and bone disease. Increased rates of vitamin D deficiency, elevated laboratory markers of bone turnover and increased rates of osteopenia, osteomalacia and fracture have all been reported. Although most commonly attributed to anticonvulsants that induce hepatic cytochrome P450 (CYP) enzymes, recent studies suggest that valproate, a CYP inhibitor, is also problematic. Data specific to other newer AEDs are lacking. Drug-induced inactivation of vitamin D is the most widely proposed mechanism for AED-related bone disease, however, other not yet fully elucidated pathways must also contribute. There are currently no evidence-based guidelines for diagnosis or treatment of bone disease specific to persons on AED therapy. Periodic screening for vitamin D deficiency and with dual-energy x-ray absorptiometry is likely beneficial. Prophylactic supplementation with vitamin D and calcium can be considered for all patients on AEDs, unless ...
越来越多的证据表明抗癫痫药物(aed)与骨病有关。据报道,维生素D缺乏率增加,骨转换实验室指标升高,骨质减少、骨软化和骨折发生率增加。虽然最常见的原因是抗惊厥药可诱导肝细胞色素P450 (CYP)酶,但最近的研究表明,CYP抑制剂丙戊酸盐也有问题。缺乏其他新型aed的具体数据。药物诱导的维生素D失活是aed相关骨病最广泛提出的机制,然而,其他尚未完全阐明的途径也必须起作用。目前,对于接受AED治疗的患者,尚无基于证据的骨病诊断或治疗指南。定期筛查维生素D缺乏症并使用双能x射线吸收仪可能是有益的。预防性补充维生素D和钙可以考虑所有的aed患者,除非…

Can diet modifications play a preventative role in the onset of Alzheimer’s disease? 饮食改变能否在阿尔茨海默病的发病中起到预防作用?
Pub Date : 2008-01-31 DOI: 10.2217/1745509X.4.1.1

Alzheimer’s disease (AD) is a growing public health concern with potentially devastating effects. At present, there are no methods of prevention or any known cures for the disease. While genetic factors are relevant in early-onset cases, they are less relevant in late-onset sporadic AD, which is the most common form [1]. Research seeking to find drugs to slow its progression may pay off – someday. However, as the disease typically strikes very late in life, delaying its symptoms could be a good cure for many people. For example, it is now widely accepted that delaying the onset of the disease by even 5 years can cut its incidence in half. Indeed, clinical and epidemiological evidence points to lifestyle factors, including nutrition, as being crucial in delaying the onset of AD. Mounting evidence suggests that brain cells are remarkably responsive to what somebody is doing or eating. Among other nongenetic factors influencing AD, recent studies strongly support the hypothesis that certain dietary factors, such as the Mediterranean diet, may play a beneficial role in the relative risk for AD clinical dementia. Indeed, the effect of diet in AD has been an area of research that has produced enlightening results. More importantly, the evidence supporting a direct link between nutrition and AD neuropathology and dementia continues to grow, as the mechanistic pathways are defined and their biochemical functions scrutinized. Most remarkably, there is also evidence that high caloric intake in the form of saturated fat promotes AD-type neuropathology and, conversely, caloric restriction via reduced carbohydrate intake can prevent it. This evidence is very exciting and is consistent, in part, with current epidemiological studies, which suggest that obesity and diabetes are associated with a more than fourfold increased risk for developing AD. Clarifying the mechanisms through which certain dietary lifestyle factors and caloric intake may ultimately influence AD neuropathology will provide new avenues for the design of ‘therapeutic lifestyle strategies’ to treat AD, and possibly other neurodegenerative disorders.
阿尔茨海默病(AD)是一个日益严重的公共卫生问题,具有潜在的破坏性影响。目前,没有预防这种疾病的方法,也没有任何已知的治疗方法。虽然遗传因素与早发性AD相关,但与迟发性散发AD相关性较低,而迟发性散发AD是最常见的形式。寻找减缓其发展的药物的研究可能会在某一天取得成功。然而,由于这种疾病通常发生在生命的晚期,延迟其症状对许多人来说可能是一种很好的治疗方法。例如,现在人们普遍认为,即使将疾病的发病推迟5年,也可以将其发病率降低一半。事实上,临床和流行病学证据表明,包括营养在内的生活方式因素在延缓阿尔茨海默病发病方面起着至关重要的作用。越来越多的证据表明,大脑细胞对某人正在做的事情或吃的东西有明显的反应。在影响阿尔茨海默病的其他非遗传因素中,最近的研究强烈支持这样的假设,即某些饮食因素,如地中海饮食,可能在阿尔茨海默病临床痴呆的相对风险中发挥有益作用。事实上,饮食对阿尔茨海默病的影响一直是一个研究领域,已经产生了启发性的结果。更重要的是,支持营养与阿尔茨海默病神经病理和痴呆症之间直接联系的证据在不断增加,因为机制途径被明确,它们的生化功能被仔细研究。最值得注意的是,还有证据表明,以饱和脂肪形式摄入的高热量会促进ad型神经病理学,相反,通过减少碳水化合物摄入来限制热量可以预防ad型神经病理学。这一证据非常令人兴奋,并且在一定程度上与目前的流行病学研究一致,这些研究表明,肥胖和糖尿病与患AD的风险增加四倍以上有关。阐明某些饮食生活方式因素和热量摄入可能最终影响阿尔茨海默病神经病理的机制,将为设计治疗性生活方式策略来治疗阿尔茨海默病,以及其他可能的神经退行性疾病提供新的途径。

Systemic infections after acute stroke 急性中风后全身性感染
Pub Date : 2008-01-31 DOI: 10.2217/1745509X.4.1.85
J. Kwan, D. Jenkinson, M. Vassallo, N. Englyst, V. Perry
After an acute stroke, systemic infection can complicate the recovery process and lead to a worse clinical outcome, including a higher risk of mortality. Post-stroke infection (PSI) is responsible for the majority of the mortality occurring between 1 week and 1 month after stroke, peaking towards the end of the second week. The effects of PSI on longer-term outcome and other aspects of recovery, such as cognition, mood and quality of life, are largely unknown. The cerebrovascular event itself may result in a systemic immunosuppressed state, hence lowering the threshold for subsequent systemic bacterial infections. Although there have been advances in the basic understanding of the pathophysiological mechanisms of PSI, clinical studies have not provided any clear guidelines on the best methods of managing or preventing PSI. This article provides a review of the current knowledge of the phenomenon of PSI and the possible future developments in the understanding and treatment of PSI.
急性中风后,全身感染会使恢复过程复杂化,并导致更糟糕的临床结果,包括更高的死亡风险。卒中后感染(PSI)是卒中后1周至1个月死亡的主要原因,在第二周结束时达到高峰。PSI对长期结果和康复的其他方面的影响,如认知、情绪和生活质量,在很大程度上是未知的。脑血管事件本身可能导致全身性免疫抑制状态,从而降低随后全身性细菌感染的阈值。虽然对PSI的病理生理机制的基本认识已经取得了进展,但临床研究并没有提供任何关于管理或预防PSI的最佳方法的明确指导。本文综述了目前对PSI现象的认识,以及对PSI的认识和治疗可能的未来发展。

Hypothermia in the geriatric population 老年人群的体温过低
Pub Date : 2007-12-12 DOI: 10.2217/1745509X.3.6.735

Hypothermia is common in the geriatric population and its significance perhaps under-recognized. Hypothermia is associated with substantial morbidity and fatality, but to some extent is preventable provided caregivers and providers of healthcare to older adults adopt preventive measures to lower its occurrence. Hypothermia occurs in both cold and warm settings; its pathogenesis involves alterations in the age-related physiology of thermoregulation, along with a variable combination of environmental factors, disease processes and medications, many of which are recognizable. Once diagnosed, treatment must be prompt and aggressive, and must consider several options for rewarming. Education of healthcare providers regarding early recognition of hypothermia and a better understanding of preventive and treatment measures will undoubtedly lower complications of hypothermia in affected elderly.
体温过低在老年人群中很常见,但其重要性尚未得到充分认识。体温过低与大量发病率和死亡率相关,但在一定程度上是可以预防的,前提是老年人的护理人员和医疗保健提供者采取预防措施来降低其发生率。低温症在寒冷和温暖的环境中都会发生;其发病机制涉及与年龄相关的体温调节生理学的改变,以及环境因素、疾病过程和药物的可变组合,其中许多是可识别的。一旦确诊,治疗必须及时和积极,必须考虑几种复温的选择。教育卫生保健提供者尽早认识低体温和更好地了解预防和治疗措施无疑将降低老年患者的低体温并发症。

Geriatric challenge: how to cure incontinence with a screwdriver 老年人的挑战:如何用螺丝刀治疗尿失禁

As a resident in geriatric medicine, I walked past the staff notice board one afternoon on the way to the emergency intake unit of the hospital with the knowledge that a long night was ahead of me. I cast a casual glance at the notices of forthcoming seminars, journal clubs, lectures, conferences – and one caught my eye. The next day at noon, a certain Professor Bernard Isaacs would be delivering a lecture on the topic of incontinence in the elderly. Well, the subject was certainly of interest to me, and we would most definitely be asked about incontinence in the imminent qualifying examination in geriatric medicine. On the other hand, I was sure that my exhaustion after a night in emergency would get the better of me and I would probably go home to sleep and miss the lecture. The night was, needless to say, rather eventful – an 90-year-old man with atrial fibrillation and pulmonary edema, a 76-year-old woman with dementia who fell and fractured her femur, a frail lady in her early 80s with pneumonia who required mechanical ventilation, to mention but a few. The next morning, after handing the patients over to the day staff and updating all the charts, I suddenly recalled that there was a lecture on the topic of incontinence at noon. A few sips of strong coffee and I was on the way to the lecture. The chairman introduced Bernard Isaacs, Professor of Geriatric Medicine at Birmingham University in the UK, as one of the leading geriatricians of this generation. Isaacs had characterized the principal symptoms affecting the elderly as the ‘Geriatric Giants’, these being incontinence, immobility, instability (resulting in falls) and intellectual impairment. He would now enlighten the audience with a talk on one of the Giants – incontinence. Bernard Isaacs, a balding man with an infectious smile, commenced his lecture with the following statement:
作为一名老年医学的住院医师,一天下午,在去医院急诊室的路上,我经过了员工布告栏,我知道我将度过一个漫长的夜晚。我不经意地瞥了一眼即将召开的研讨会、期刊俱乐部、讲座和会议的通知,其中一个引起了我的注意。第二天中午,有个叫伯纳德·艾萨克斯的教授要做一场关于老年人大小便失禁的讲座。我当然对这个话题很感兴趣,在即将到来的老年医学资格考试中我们肯定会被问到失禁的问题。另一方面,我确信在紧急情况下度过一夜之后,我的疲惫会让我变得更好,我可能会回家睡觉,错过讲座。不用说,那天晚上是相当多事的——一位患有房颤和肺水肿的90岁老人,一位76岁的老年痴呆症患者摔倒并股骨骨折,一位80岁出头的虚弱女士患有肺炎,需要机械通气,仅举几例。第二天早上,在把病人交给日间工作人员并更新了所有的图表后,我突然想起中午有一场关于大小便失禁的讲座。喝了几口浓咖啡,我就上路去听课了。主席介绍了英国伯明翰大学老年医学教授伯纳德·艾萨克斯(Bernard Isaacs),他是这一代领先的老年医学专家之一。艾萨克斯将影响老年人的主要症状描述为"老年巨人",这些症状包括大小便失禁、行动不便、身体不稳(导致跌倒)和智力损伤。现在,他要给听众讲一讲其中一个巨人——尿失禁。伯纳德·艾萨克斯,一个秃顶的男人,带着富有感染力的微笑,开始了他的演讲:
