JAMDA:老人患肌肉减少症会带来哪些危害

2015-07-15 MedSci MedSci原创

目的:若患肌肉减少症,则会带来一系列不良后果。本研究的目的是探究:参与CHAMP计划的社区老年男性肌肉减少症患者的病情严重程度与患者日常生活活动能力(ADL)、是否住院及与患者死亡率之间的关系。方式:该实验在2005-2007年间选取1705名年龄在70岁以上的澳大利亚悉尼男性社区居民,并采用纵向分析以得出实验结论。我们关注的主要指标是居民的ADL日常生活能力、是否住院或者入住养老院及老人死亡率。

目的:若患肌肉减少症,则会带来一系列不良后果。本研究的目的是探究:参与CHAMP计划的社区老年男性肌肉减少症患者的病情严重程度与患者日常生活活动能力(ADL)、是否住院及与患者死亡率之间的关系。


方式:该实验在2005-2007年间选取1705名年龄在70岁以上的澳大利亚悉尼男性社区居民,并采用纵向分析以得出实验结论。我们关注的主要指标是居民的ADL日常生活能力、是否住院或者入住养老院及老人死亡率。我们对1705名参与者进行了基础评估测试,一共1678名老人(平均年龄为77岁)进行了双能x线测量法检测,并使用国家卫生院(FNIH)的标准,通过测量老人四肢肌肉脂肪含量降低(ALM)进而得出老人是否患有肌肉减少症。

为了区分患者肌肉减少症的严重程度,我们进行了以下划分:仅有低ALM为1级,低ALM伴有身体虚弱者为2级,伴有低ALM和身体虚弱同时步速很慢者为3级。我们使用Cox比例风险模型和Logistic回归模型来评估患者的死亡率和住院情况,及患者日常生活活动能力障碍的发生率。

结果:经由基础测试和后续随访,有103位(占11.3%)老人日常生活能力存在障碍,191位(占11.2%)老人被收入院或转入养老院,535位(占31.9%)老人死亡。基础测试得知,有14.2%的老人为肌肉减少症1级,5.3%的老人为2级,3.7%的老人为3级。我们通过调整多种因素(包括人口统计学因素、生活方式、老人患的并发症、和血型),发现肌肉减少症的级别越高则会导致肢体活动受限、住院、死亡的风险增加。肌肉减少症1、2、3级与肢体活动受限程度的关系分别为:优势比(OR)为2.77 95%可信区间为1.30–5.87;OR为3.78,95% CI 为1.23–11.64;OR为4.53,95% CI为0.90–22.72; 与住院风险的关系分别为:风险比(HR)为1.96 ,95% CI 为1.14–3.35,;HR 2.53 ,95% CI 1.31–4.90; HR 2.27, 95% CI 1.08–4.80;与患者死亡率的关系为:HR 1.65 ,95% CI 1.30–2.09,;HR 1.50, 95% CI 1.08–2.08;HR 1.69 ,95% CI 1.17–2.44.

结论:该研究表明对于社区老年男性居民而言,患肌肉减少症会导致机体日常活动受限、入院及死亡的风险加大。

JAMDA:使用辅助生活设施的痴呆老人住院率居高不下

目的:辅助生活(AL)设施是老年痴呆患者居家生活的更多选择。 然而,人手不足和辅助生活要求提高或许会为选择辅助生活的老人带来一定的风险和不良后果。我们实验的目的在于探究住院超过1年的老年痴呆患者,相比长期护理设施的条件而言,他们特定的辅助生活(DAL) 设施的条件如何;并且探究导致选择DAL生活的老人住院的一些居住条件和设施条件。方式:我们选取了609名DAL居民(平均年龄为85.7± 6.6岁)

目的:该实验的目的是探究养老院全科医生的数目是否会影响医生开具不适当的精神类药品处方。方式:该实验为横断面研究。研究地点在法国175家养老院进行。参与人员为2011年5月到7月入住的6275名居民。我们关注的主要指标:是依据法国的处方指导和改进指南,发现是否有不当的精神病药物处方。养老院的医生通过电子设备记录居民特征和养老院的设施特征。由于数据的层次结构(居民居住水平和养老院护理的水平),我们采用

Int J Nurs Stud:关于老人健康认知能力的综述

背景:尽管针对老年人的老年医学研究并不少见,但是很少人会关注到老人本身对身体健康的认知和感知程度。理解老人对自身健康的认知程度十分重要,因为他们的自我认知能力是反映身体健康程度的重要指标,并且与他们的生存状况和死亡率有密切关联。年纪不同,对健康的自我认知能力也不同。老人对健康的自我认知能力与他们的年龄、疾病、肢体受限情况等都有关系。并且老人和医生对老人本身健康状况的认知也有差异。目标:这篇系统综述

JAMDA:独自吃饭,老人会得抑郁症!

目的:老人抑郁已成为老龄化国家的严峻挑战。与之相关的高危因素包括个人空闲时间增多,但是用餐时间缺乏社会交往,例如独自一人吃饭。这个问题尚未得以广泛研究,尤其是讨论其与生活安排的关系。既往的研究主要关注老人的社会参与和抑郁症之间的关联变化及发展方向,但这个研究仍然是不够的。本研究旨在探讨老人的社会参与和抑郁症状(重点关注老人单独吃饭)之间的关联,同时描述老人年龄与脆弱的精神状态之间的关系及其发展轨迹

目的:一些研究强调患者的血管改变和认知能力下降之间存在一定的联系。该研究表明,通过颈股动脉脉搏波速度(CFPWV)评估的动脉血管硬化与非常年老体弱的人一年内具有更明显的认知功能下降相关。本分析的目的是评估一些2年内认知功能下降很明显且身体非常虚弱的老人的血流动力学参数,如血压(BP),心率(HR),CFPWV,和中央/外周脉压放大率(PPA)。方式:一共682名生活在法国和意大利养老院的老人参与了

JAMDA:虚弱指数影响养老院患者死亡率

目的:本研究的目的是探讨一种与年龄有关的死亡风险指数(即所谓的虚弱指数,由罗克伍德提出)用于预测养老院的人口死亡率的能力。方式:该研究为纵向队列研究,参与人员为来自法国的13个养老院共计773名老人(女性占74.4%),主要探究其肺炎和肺炎相关并发症的发生率及患者的死亡率。我们在实验前对患者进行评估,FI被用于计算在30个潜在的死亡风险中患者实际的风险比例(0 [无风险]和1 [ 存在风险])。我
