Sarcopenia is the age-related loss of skeletal muscle mass and muscle strength or physical function. It is most common in elderly individuals. Due to its high incidence, insidious onset, and extensive impact on the body, it has a huge impact on the family medical burden and the social public health expenditure in China. The understanding of sarcopenia in China is still lacking, and the recommendations for prevention, control, and intervention are not clear and unified. The purpose of this consensus report is to standardize the prevention, control, and intervention methods for sarcopenia in elderly patients in China; improve the efficacy of intervention; reduce complications during the intervention process; and reduce the risk of falls, fractures, disability, hospitalization, and even death in elderly individuals.

骨骼肌减少症是与年龄有关的骨骼肌质量、肌肉力量或身体功能的丧失。它在老年人中最常见。由于其发病率高、发病隐匿、对身体影响广泛,对中国家庭医疗负担和社会公共卫生支出产生了巨大影响。国内对肌肉减少症的认识还很缺乏,预防、控制和干预的建议也不明确、不统一。本共识报告旨在规范中国老年患者肌肉减少症的预防、控制和干预方法;提高干预效果;减少干预过程中的并发症;降低老年人跌倒、骨折、残疾、住院甚至死亡的风险。

Objective

To compare clinical outcomes between patients for whom their participation in inpatient rehabilitation was and was not impacted by dementia through matching patients reporting dementia (dementia group) with those not reporting dementia (non-dementia group).

Methods

Prospectively collected data held by the Australasian Rehabilitation Outcome Centre (AROC) were analyzed for patients aged 65 years or older receiving inpatient rehabilitation in public hospitals in Australia following a hip fracture and discharged between July 1, 2014, and June 30, 2019. Patients reported as having dementia impacting their rehabilitation program were matched to patients not reporting dementia based on age, admission motor Functional Independence Measure (FIM) score, and accommodation prior to rehabilitation. The matched cohorts were compared in relation to clinical outcomes (motor and cognitive FIM improvement, FIM efficiency, length of stay, and discharge destination) following participation in hospital-based rehabilitation using univariate analysis.

Results

Patients with dementia had significantly lower cognitive FIM scores on commencing rehabilitation (17.6 and 26.9, respectively, P < 0.001) and their median length of stay was 2 days shorter than those without dementia (21 and 23 days, respectively, P < 0.001). Relative change in FIM score and FIM efficiency (per week) were lower in the dementia group [relative FIM score change of dementia vs non-dementia, respectively, 26.2% vs. 44.0% (P < 0.001) and FIM efficiency, 6.5 vs. 8.9 (P < 0.001)]. Discharge destination between the two groups was statistically different, with 35.7% of patients with dementia being discharged to residential aged care facilities (RACFs) compared to 21.7% of those without dementia (P < 0.001). More patients with dementia had carers in their private residence in the post-rehabilitation phase, 82.2% vs. 57.6% (P < 0.001).

Conclusion

Patients with dementia who sustain a fractured hip benefit from inpatient rehabilitation, although their clinical outcomes are not as good as those without dementia. FIM change and FIM efficiency were lower in the dementia group. Length of stay in the hospital for patients with dementia was shorter due to earlier recognition for the need for placement in either an RACF or at home with carer support.

目的通过将报告痴呆的患者(痴呆组)与未报告痴呆的患者(非痴呆组)进行匹配,比较住院康复受痴呆影响和不受痴呆影响的患者的临床结果。方法前瞻性收集澳大利亚康复结果中心(AROC)持有的数据,分析2014年7月1日至2019年6月30日期间在澳大利亚公立医院接受髋部骨折住院康复并出院的65岁及以上患者。根据年龄、入院运动功能独立测量(FIM)评分和康复前的住宿情况,将报告患有痴呆症的患者与未报告患有痴呆症的患者进行匹配。采用单变量分析比较匹配队列参与医院康复后的临床结果(运动和认知FIM改善、FIM效率、住院时间和出院目的地)。结果痴呆患者在康复开始时的认知FIM评分显著低于无痴呆患者(分别为17.6和26.9,P < 0.001),其中位住院时间比无痴呆患者短2天(分别为21和23天,P < 0.001)。痴呆组FIM评分和FIM效率(每周)的相对变化较低[痴呆组与非痴呆组FIM评分的相对变化分别为26.2%对44.0% (P < 0.001)和6.5对8.9 (P < 0.001)]。两组患者的出院目的地有统计学差异,有35.7%的痴呆患者出院到住宅老年护理机构(RACFs),而无痴呆患者出院到住宅老年护理机构的比例为21.7% (P < 0.001)。在康复后阶段,更多的痴呆患者在其私人住宅中有照顾者,82.2%比57.6% (P < 0.001)。结论失智性髋部骨折患者的住院康复效果优于非失智性髋部骨折患者。痴呆组的FIM变化和FIM效率较低。痴呆症患者住院时间较短,因为他们较早认识到需要安置在儿童福利院或有护理人员支持的家中。在痴呆症组中,需要安置在RACF或私人住宅的护理人员支持的需求显着增加。

Introduction

Polypharmacy is a growing phenomenon associated with adverse effects in older adults. We assessed the potential confounding effects of cumulative anticholinergic burden (ACB) in patients who were hospitalized with falls.

Methods

A noninterventional, prospective cohort study of unselected, acute admissions aged ≥ 65 years. Data were derived from electronic patient health records. Results were analyzed to determine the frequency of polypharmacy and degree of ACB and their relationship to falls risk. Primary outcomes were polypharmacy, defined as prescription of 5 or more regular oral medications, and ACB score.

Key Results

Four hundred eleven (411) consecutive subjects were included, mean age 83.8 ± 8.0 years: 40.6% men. There were 38.4% patients who were admitted with falls. Incidence of polypharmacy was 80.8%, (88.0% and 76.3% among those admitted with and without fall, respectively). Incidence of ACB score of 0, 1, 2, ≥ 3 was 38.7%, 20.9%, 14.6%, and 25.8%, respectively. On multivariate analysis, age [odds ratio (OR) = 1.030, 95% CI:1.000 ~ 1.050, P = 0.049], ACB score (OR = 1.150, 95% CI:1.020 ~ 1.290, P = 0.025), polypharmacy (OR = 2.140, 95% CI:1.190 ~ 3.870, P = 0.012), but not Charlson Comorbidity Index (OR = 0.920, 95% CI:0.810 ~ 1.040, P = 0.172) were significantly associated with higher falls rate. Of patients admitted with falls, 29.8% had drug-related orthostatic hypotension, 24.7% had drug-related bradycardia, 37.3% were prescribed centrally acting drugs, and 12.0% were taking inappropriate hypoglycemic agents.

Conclusion

Polypharmacy results in cumulative ACB and both are significantly associated with falls risk in older adults. The presence of polypharmacy and each unit rise in ACB score have a stronger effect of increasing falls risk compared to age and comorbidities.

多药是一种日益增长的与老年人不良反应相关的现象。我们评估了因跌倒住院的患者累积抗胆碱能负荷(ACB)的潜在混杂效应。方法对年龄≥65岁的未选择急性入院患者进行非干预性前瞻性队列研究。数据来源于电子患者健康记录。对结果进行分析,确定多药发生频率、ACB程度及其与跌倒风险的关系。主要结局是多药,定义为处方5种或更多常规口服药物,以及ACB评分。纳入411例连续受试者,平均年龄83.8±8.0岁,男性占40.6%。38.4%的患者因跌倒入院。多药的发生率为80.8%(住院时伴有跌倒的占88.0%,未伴有跌倒的占76.3%)。ACB评分为0、1、2、≥3的发生率分别为38.7%、20.9%、14.6%、25.8%。多因素分析显示,年龄[比值比(OR) = 1.030, 95% CI:1.000 ~ 1.050, P = 0.049]、ACB评分(OR = 1.150, 95% CI:1.020 ~ 1.290, P = 0.025)、多药治疗(OR = 2.140, 95% CI:1.190 ~ 3.870, P = 0.012)与较高的跌倒率相关,而Charlson合病指数(OR = 0.920, 95% CI:0.810 ~ 1.040, P = 0.172)与较高的跌倒率无关。在因跌倒入院的患者中,29.8%的患者有药物相关性直立性低血压,24.7%的患者有药物相关性心动过缓,37.3%的患者使用中央作用药物,12.0%的患者使用不适当的降糖药。结论多种药物导致累积ACB,两者与老年人跌倒风险显著相关。与年龄和合并症相比,多药的存在和ACB评分每增加一个单位对增加跌倒风险的影响更大。

Background

Inflammation and altered lipid dyshomeostasis have been implicated in the pathogenesis of Alzheimer's disease and vascular dementia.

Objective

To determine if there are any associations between dietary patterns, plasma lipid profiles, and inflammatory potential in a vascular dementia cohort.

Methods

One hundred fifty participants (36 subjects with Vascular Dementia and 114 healthy controls) from two Australian teaching hospitals completed a cross-sectional survey examining their dietary and lifestyle patterns. Each participant's diet was further evaluated using the Empirical Dietary Inflammatory Index. Some participants also donated blood samples for lipidomic analysis.

Results

After adjusting for age, education, and socioeconomic status, participants with vascular dementia tend to have higher lipid profiles, do less exercise, and engage less frequently in social interaction, educational, or reading activities. They also tend to consume more deep-fried food and full-fat dairy compared to control subjects. However, there was no difference in Empirical Dietary Inflammatory Index between the two groups after adjusting for age, education, and socioeconomic status.

Conclusion

Our findings suggest a graded inverse association between healthy lifestyle factors and vascular dementia.

炎症和脂质失衡的改变与阿尔茨海默病和血管性痴呆的发病机制有关。目的探讨血管性痴呆患者的饮食模式、血脂和炎症潜能之间是否存在关联。方法来自澳大利亚两家教学医院的150名参与者(36名血管性痴呆患者和114名健康对照者)完成了一项横断面调查,调查了他们的饮食和生活方式。使用经验性饮食炎症指数进一步评估每位参与者的饮食。一些参与者还捐献了血液样本用于脂质组学分析。在调整了年龄、受教育程度和社会经济地位后,血管性痴呆患者的血脂水平较高,运动较少,参与社会互动、教育或阅读活动的频率较低。与对照组相比,他们也倾向于食用更多的油炸食品和全脂乳制品。然而,在调整了年龄、教育程度和社会经济地位后,两组之间的经验饮食炎症指数没有差异。结论:健康生活方式因素与血管性痴呆呈负相关关系。

Background

Cancer incidence is expected to increase with population aging, making the availability of places for treating patients with terminal cancer a pressing issue. However, little is known about the actual state of home end-of-life care (HEC) in Japan.

Objective

The objective of this study was to examine the real-world state of HEC for older adults with cancer.

Methods

The Yokohama Original Medical Database was used to identify the cohort. Data of target patients was extracted based on three criteria: age ≥65 years, malignant neoplasm diagnosis, and having a specific billing code of HEC. Multivariable linear and logistic regression models were used to evaluate the association between age groups and HEC services or outcome indexes.

Results

Overall, 1323 people (554 and 769 aged < 80 and ≥ 80 years, respectively; men, 59.2%) had planned to receive HEC. The < 80 years group had more frequent emergent home visits than the ≥ 80-year group (P < 0.001), but the number of monthly home visits was similar between the two groups (P = 0.267). The rate of emergent admission was 5.9% in the ≥ 80-year group, which was higher than that in the < 80-year group (3.1%; P = 0.018). Conversely, the rates of central venous nutrition and opioid use were higher in the < 80-year group than those in the ≥ 80-year group.

Conclusions

This study reported patterns of use of HEC among older adults with cancer in the terminal stage. Our findings may provide the basis for providing HEC for older adults with cancer.

随着人口老龄化,癌症发病率预计会增加,这使得为晚期癌症患者提供治疗场所成为一个紧迫的问题。然而,人们对日本家庭临终关怀(HEC)的实际状况知之甚少。本研究的目的是检查老年癌症患者HEC的真实状态。方法采用横滨原始医学数据库进行队列识别。目标患者的数据提取基于三个标准:年龄≥65岁,恶性肿瘤诊断,具有HEC的特定计费代码。采用多变量线性和逻辑回归模型评估年龄与HEC服务或结局指标之间的关系。结果共1323例患者(80岁和≥80岁分别为554例和769例;男性(59.2%)曾计划接受HEC。80岁组紧急家访频率高于≥80岁组(P < 0.001),但两组月家访次数相似(P = 0.267)。≥80岁组急诊住院率为5.9%,高于≥80岁组(3.1%;p = 0.018)。相反,80岁以上年龄组的中心静脉营养和阿片类药物使用率高于80岁以上年龄组。本研究报告了晚期老年癌症患者使用HEC的模式。我们的发现可能为老年癌症患者提供HEC提供基础。

Objective

To estimate the hypothetical effects of substituting time spent in moderate-to-vigorous physical activity (MVPA) and time spent in sedentary behavior (SB) and their associations with diabetes.

Methods

A cross-sectional study using exploratory survey methods was performed in Alcobaça city in the state of Bahia, Brazil in the year 2015. A total of 473 older adults (aged ≥60 years) participated in the study. Diabetes mellitus, time MVPA, and SB were assessed in a self-reported manner. The Poisson regression was used to verify the hypothetical effects of the substitution of MVPA with SB on diabetes.

Results

The substitution of the time in MVPA with time in SB showed higher prevalence ratios of diabetes. Conversely, the substitution of the time in SB proved to be a protective factor, with risks reduced by between 4% and 19%.

Discussion

The substitution of the time spent in MVPA with the same amount of time spent on SB can lead to an increase in the probability of diabetes, and a longer reallocation time corresponded to a greater risk.

目的评估中高强度体力活动(MVPA)和久坐行为(SB)替代的假设效应及其与糖尿病的关系。方法采用探索性调查方法,于2015年在巴西巴伊亚州阿尔科巴帕拉达市进行横断面研究。共有473名老年人(年龄≥60岁)参与了这项研究。以自我报告的方式评估糖尿病、时间MVPA和SB。用泊松回归验证了用SB替代MVPA对糖尿病的假设影响。结果用SB时间代替MVPA时间显示糖尿病患病率较高。相反,在SB中替换时间被证明是一个保护因素,风险降低了4%到19%。在MVPA上花费的时间与在SB上花费的时间相同,可以导致糖尿病的概率增加,并且更长的重新分配时间对应于更大的风险。

Objective

Head trauma, a cause of serious morbidity and mortality in general, is among the most common causes of emergency department visits in geriatric patients. In this context, this study investigated the factors affecting prognosis and mortality in geriatric patients presenting with head trauma at the emergency department.

Methods

This retrospective cohort study included 842 patients aged 65 years and above who presented with head trauma to the emergency department between January 1, 2019, and December 31, 2019. Demographic and clinical data of the 622 patients included in the study were analyzed.

Results

A total of 622 geriatric patients with head trauma were included in this study. Of these, 54.2% (337/622) were men, and 45.8% (285/622) were women. The mean age of the patients was 75.3 ± 7.5 years. Antihypertensives were the most common medications taken by the patients. Subdural hematoma is the most frequently observed cranial pathology. A simple fall is the most observed mechanism for trauma. A total of 17.5% (109/622) of the patients were admitted to the hospital. Of these patients, 8.4% (52/622) were transferred to the intensive care unit and 2.6% (16/622) of the patients died.

Conclusion

Mortality would be expected to be higher in elderly patients with head trauma, hypotension, or high lactate levels. The need for intensive care unit transfer was higher in patients with coronary artery disease. The mortality rate of the patients increased with an increasing length of hospital stay.

Older adults are at high risk for functional impairment, which is closely related to sarcopenia, falls, and frailty. This seriously affects their quality of life and health, and places a heavy burden on society and families. Although domestic and foreign sports recommendations and prevention and control guidelines/expert consensus have been issued for healthy older adults and functional impairment-related diseases, there is no guidance on prevention and control interventions for older adults with physical functional impairment. In China, there is insufficient understanding of the importance of prevention and control interventions for functional impairment in older adults, and there are many drawbacks, such as unstandardized diagnosis and treatment, and relatively simple intervention methods. Therefore, the consensus expert group formulated a consensus based on domestic and foreign guidelines related to functional impairment in older adults to provide guidance for Chinese medical professionals working in the field of geriatrics.

老年人是功能损害的高危人群,与肌肉减少症、跌倒和虚弱密切相关。这严重影响到他们的生活质量和健康,给社会和家庭带来沉重负担。虽然国内外已经针对健康老年人和功能损伤相关疾病发布了体育运动建议和防控指南/专家共识,但目前尚无针对老年人身体功能损伤的防控干预措施指导。国内对老年人功能障碍防治干预措施的重要性认识不足,存在诊断和治疗不规范、干预方法相对单一等诸多弊端。因此,共识专家组在借鉴国内外老年人功能障碍相关指南的基础上,制定了共识,为我国从事老年医学领域工作的医务人员提供指导。

In hospitalized patients the prevalence of constipation is high, especially among elderly patients. Constipation impacts significantly the quality of life of patients and is associated with increased morbidity and length of hospital stay. This retrospective observational study intended to identify the prevalence of constipation in patients hospitalized in an internal medicine ward. In a sample of 80 patients, the median age was 79 years and 53% (n = 42) were women. We identified constipation in 68% (n = 56) of the patients during hospitalization. The medical team prescribed treatment only to 70% of those patients. Constipation was responsible for delirium in 11% of patients and 5% suffered urinary retention. This study shows constipation is prevalent among patients admitted in an internal medicine ward. Systematic assessment of this problem can improve the overall care of the patients, alleviate symptoms, and prevent complications.

在住院患者中,便秘的患病率很高,特别是在老年患者中。便秘显著影响患者的生活质量,并与发病率和住院时间增加有关。本回顾性观察性研究旨在确定在内科病房住院的患者便秘的患病率。在80例患者的样本中,中位年龄为79岁,53% (n = 42)为女性。我们发现68% (n = 56)的患者在住院期间出现便秘。医疗团队只给70%的病人开了处方。便秘导致11%的患者出现谵妄,5%的患者出现尿潴留。这项研究表明,在内科病房住院的病人中,便秘很普遍。系统评估这一问题可以改善患者的整体护理,减轻症状,预防并发症。

Characteristics of circulating small noncoding RNAs in plasma and serum during human aging 人类衰老过程中血浆和血清循环小非编码rna的特征
Pub Date : 2023-02-22 DOI: 10.1002/agm2.12241

Objective

Aging is a complicated process that triggers age-related disease susceptibility through intercellular communication in the microenvironment. While the classic secretome of senescence-associated secretory phenotype (SASP) including soluble factors, growth factors, and extracellular matrix remodeling enzymes are known to impact tissue homeostasis during the aging process, the effects of novel SASP components, extracellular small noncoding RNAs (sncRNAs), on human aging are not well established.

Methods

Here, by utilizing 446 small RNA-seq samples from plasma and serum of healthy donors found in the Extracellular RNA (exRNA) Atlas data repository, we correlated linear and nonlinear features between circulating sncRNAs expression and age by the maximal information coefficient (MIC) relationship determination. Age predictors were generated by ensemble machine learning methods (Adaptive Boosting, Gradient Boosting, and Random Forest) and core age-related sncRNAs were determined through weighted coefficients in machine learning models. Functional investigation was performed via target prediction of age-related miRNAs.

Results

We observed the number of highly expressed transfer RNAs (tRNAs) and microRNAs (miRNAs) showed positive and negative associations with age respectively. Two-variable (sncRNA expression and individual age) relationships were detected by MIC and sncRNAs-based age predictors were established, resulting in a forecast performance where all R2 values were greater than 0.96 and root-mean-square errors (RMSE) were less than 3.7 years in three ensemble machine learning methods. Furthermore, important age-related sncRNAs were identified based on modeling and the biological pathways of age-related miRNAs were characterized by their predicted targets, including multiple pathways in intercellular communication, cancer and immune regulation.

Conclusion

In summary, this study provides valuable insights into circulating sncRNAs expression dynamics during human aging and may lead to advanced understanding of age-related sncRNAs functions with further elucidation.

衰老是一个复杂的过程,它通过微环境中的细胞间通讯触发与年龄相关的疾病易感性。虽然已知衰老相关分泌表型(SASP)的经典分泌组,包括可溶性因子、生长因子和细胞外基质重塑酶,在衰老过程中影响组织稳态,但新的SASP成分,细胞外小非编码rna (sncRNAs)对人类衰老的影响尚未得到很好的证实。方法利用细胞外RNA (exRNA) Atlas数据库中健康供者血浆和血清中的446个小RNA-seq样本,通过最大信息系数(MIC)关系确定循环sncRNAs表达与年龄之间的线性和非线性特征。年龄预测因子通过集成机器学习方法(自适应增强、梯度增强和随机森林)生成,并通过机器学习模型中的加权系数确定核心年龄相关sncrna。通过预测与年龄相关的mirna进行功能研究。结果观察到高表达转移rna (tRNAs)和microRNAs (miRNAs)的数量分别与年龄呈正相关和负相关。通过MIC检测了两变量(sncRNA表达和个体年龄)的关系,并建立了基于sncRNA的年龄预测因子,在三种集成机器学习方法中,所有R2值均大于0.96,均方根误差(RMSE)小于3.7年。此外,基于建模鉴定了重要的年龄相关sncrna,年龄相关mirna的生物学途径通过其预测靶标来表征,包括细胞间通讯、癌症和免疫调节的多种途径。总之,本研究为人类衰老过程中循环sncRNAs的表达动态提供了有价值的见解,并可能进一步阐明与年龄相关的sncRNAs功能。
