Associations of intrinsic capacity, fall risk and frailty in old inpatients.

Introduction: This study explored the associations of intrinsic capacity (IC), fall risk, and frailty in geriatric inpatients. Methods: A total of 703 hospitalized patients aged 75 years or older were recruited for this retrospective observational study from Zhejiang Hospital using a comprehensive geriatric assessment. The IC composite score was constructed from the scores of the Chinese version of the Mini-Mental State Examination, Short Physical Performance Battery, Short Form Mini Nutritional Assessment, 15-item Geriatric Depression Scale, and self-reported hearing and vision impairment. Adverse outcomes were recorded as the fall risk and frailty using the Morse Fall Scale and the Clinical Frailty Scale. Spearman's correlation coefficient analyses and multivariate logistic regression models were used to explore the associations between IC, high fall risk, and frailty. Results: Declined IC composite scores were associated with increased risks of falls [odds ratio (OR) = 0.64, 95% confidence interval (CI): 0.57-0.72] and frailty (OR = 0.45, 95%CI: 0.37-0.54) among older hospitalized patients after adjusting for the related potential confounders. In addition, decreased cognitive, vitality, locomotion, and psychological scores were associated with increased adverse health conditions, with ORs ranging from 0.26 to 0.70. Vision impairment was observed to increase the risk of frailty (OR = 0.42, 95%CI: 0.23-0.76) after adjusting for the related potential confounders. Discussion: This study indicated that declined IC was associated with fall risk and frailty in older inpatients. Further prospective studies are needed to explore the longitudinal associations between baseline IC and subsequent risk of falls and frailty.

Association between motoric cognitive risk syndrome and frailty among older Chinese adults.

BACKGROUND: Motoric cognitive risk syndrome (MCR) is a newly proposed predementia syndrome incorporating subjective cognitive complaints and slow gait. Previous studies have reported that subjective cognitive complaints and slow gait are associated with frailty in cognitively unimpaired older adults, but little is known about the link between MCR and frailty in older adults. Therefore, the aim of the study was to explore the associations of MCR and its components with frailty in older Chinese adults. METHODS: In an observational cross-sectional study, a total of 429 older adults aged 60 years and older were admitted to the geriatric department. According to MCR criteria, all participants were classified into 4 groups: 1) the MCR group; 2) the subjective cognitive complaints only group; 3) the slow gait only group; and 4) the healthy control group. Physical frailty was assessed by the Clinical Frailty Scale (CFS). Multivariate logistic regression analysis was used to examine the association between MCR and frailty in older adults. RESULTS: The prevalence rates of subjective cognitive complaints, slow gait and MCR were 15.9, 10.0 and 4.0%, respectively. After adjusting for confounding variables, the logistic regression analysis showed that slow gait (odds ratio [OR]: 3.40, 95% confidence interval [CI]: 1.40-8.23, P = 0.007) and MCR (OR: 5.53, 95% CI: 1.46-20.89, P = 0.012) were independently associated with frailty, but subjective cognitive complaints were not. CONCLUSIONS: MCR and slow gait were significantly associated with frailty in older Chinese adults. Further studies should prospectively determine the causal relationship between MCR and frailty.

Enhancement of myocardial function and reduction of injury with levosimendan after percutaneous coronary intervention for acute myocardial infarction: a pilot study.

OBJECTIVES: To determine the short-term clinical effects of levosimendan in acute myocardial infarction (AMI) patients with myocardial stunning after emergency percutaneous coronary intervention (PCI). METHODS: The study population consisted of 30 patients with AMI who received emergency PCI and satisfied the inclusion criteria. Levosimendan was given as a continuous infusion of 0.1 µg/kg/min for 24 h, and the remaining 10 patients received placebo treatment. The patients were observed with invasive haemodynamic monitoring and were evaluated biochemically and echocardiographically before and after the drug infusion. RESULTS: Following treatment, biochemical indices (not including creatine kinase and its MB fraction) were significantly lower in the levosimendan group than in the placebo group. Meanwhile, left-ventricular (LV) end-systolic volume, mean pulmonary arterial pressure, pulmonary capillary wedge pressure and systemic vascular resistance were significantly reduced in the levosimendan group, whereas the early-to-late diastolic velocities ratio, LV ejection fraction, cardiac index and cardiac power index were increased. Troponin I levels were reduced and fewer stunned and infarction segments were observed in the patients treated with levosimendan. CONCLUSIONS: Levosimendan can significantly improve the myocardium function of patients with myocardial stunning after PCI.
