Clinical Interventions in Aging最新文献

Background: The host response plays a critical role in the progression of all critical illnesses, especially in the aging population. With aging becoming a global phenomenon, understanding changes in the host response among elderly patients can provide valuable insights for diagnosis and treatment in the ICU.

Methods: This study included all patients aged 65 and older admitted to our geriatric intensive care unit (GICU). Demographic, clinical, and medication data were extracted from electronic medical records. The primary outcome was in-hospital mortality, while secondary outcomes included hospital length of stay (LOS) and ICU stay duration. We employed the generalized additive mixed model for analysis and utilized nomogram analysis to build a predictive mortality model.

Results: A total of 1204 patients, with a median age of 75 years and a maximum age of 110 years, were admitted to the GICU. Host response biomarkers were notably lower in patients over 85 years. White blood cell (WBC) count, lactate dehydrogenase (LDH), interleukin-10 (IL-10), and tumor necrosis factor-α (TNF-α) were positively associated with mortality, while a higher platelet-to-lymphocyte ratio (PLR) was inversely related to mortality. Lymphocyte count was identified as a significant risk factor for mortality (RR = 1.2181). Elevated host response biomarkers were inversely associated with both hospital and ICU LOS. The predictive model integrating these biomarkers exhibited strong predictive performance for mortality.

Conclusion: Our findings underscore the significant impact of aging on host response in critically ill patients. Older patients, particularly those over 85, exhibited lower biomarker levels and higher mortality rates. The predictive model developed from inflammatory, immune, and coagulation markers demonstrated robust prognostic utility, aiding in the evaluation of critically ill elderly patients.

Purpose: The prevalence of osteoporosis in elderly individuals is high, and osteoporosis is strongly associated with chronic inflammation. The monocyte-to-high-density lipoprotein ratio (MHR) is acknowledged as a marker for assessing systemic inflammation and oxidative stress, and changes in the MHR are associated with many chronic disease prevalent among the elderly population. This study investigated the relationships between the MHR and the incidence of osteoporosis in older adults, along with its predictive value.

Patients and methods: Data from 563 participants aged ≥70 years were retrospectively analysed. The haematological parameters were evaluated via established methodologies, utilizing fasting blood samples collected from the participants. The absolute monocyte count was used to calculate the MHR (MHR=monocyte/HDL-C). BMD was measured by dual-energy X-ray absorptiometry. The results were evaluated via comparative statistical analyses, Spearman correlation, logistic regression analyses, and receiver operating characteristic (ROC) curve analysis.

Results: The differences in the MHR were statistically significant among the osteoporosis groups (p < 0.001). Spearman correlation analysis revealed a positive correlation between the MHR and BMD. Furthermore, stratifying the sample into four groups on the basis of quartiles of MHR (M1, M2, M3, and M4) revealed a decreased risk of osteoporosis in the highest quartile compared with the lowest quartile (p <0.001). Multiple logistic regression analysis revealed that BMI and the MHR were independent risk factors for osteoporosis. The area under the ROC curve and the cut-off value of the MHR were 0.710 and 0.308(10⁹/mmol), with specificity and sensitivity of 0.599 and 0.735, respectively (95% CI: 0.668~0.752, p < 0.0001).

Conclusion: A low MHR was associated with a greater risk of senile osteoporosis. In clinical practice, the MHR has shown predictive value for senile osteoporosis, contributing to early intervention and treatment of this disease.

Purpose: Chronic diseases in older age are major sources of burden for healthcare systems. Compliance with medications is the key to treatment success for these patients, especially for frail individuals living in community settings. However, adherence to long-term medications in this population is not optimal, which leads to the need for frequent screening of compliance within large-scale public health surveys. In this context, a brief, simple and valid measure capturing medication adherence is not yet available. This study aims to develop and psychometrically test the Therapeutic Adherence Scale, a brief four-item tool that measures medication adherence in community-dwelling older adults affected by chronic diseases.

Methods: We conducted a three-phase process of instrument development, content validity assessment and psychometric testing.

Results: Of the candidate nine items derived from a review of the literature, only four were deemed essential to capture intentional and nonintentional nonadherence. These items underwent structural validity, convergent and known-groups validity, and internal consistency on a sample of 269 participants (mean age = 7.91 years, SD = 7.26). Confirmatory factor analysis confirmed satisfactory fit indices (RMSEA = 0.000, CFI = 1.00, TLI = 1.00). Scores of the TAS were higher for those perceiving loneliness (ρ = 0.33, p < 0.001), those declaring memory loss in the last year (ρ = 0.29, p < 0.001), and those exhibiting worse mental quality of life (ρ = -0.15, p = 0.03) compared with the other groups. Cronbach's alpha and split-half reliability coefficients were acceptable, with values of 0.68 and 0.77, respectively.

Conclusion: The Therapeutic Adherence Scale is a brief, valid and reliable self-report measure of medication adherence that can be used in practice and research to screen patients living in community settings. This tool is also free to use, which contributes to advancing knowledge on the field of medication adherence of older adults affected by chronic diseases.

Background: The effects on gait and posture of balneotherapy in fallers are unknown. We assessed the effects on physical functioning and fear of falling of a balneotherapy program alone or combined with a physical activity and educational program in older adult fallers.

Methods: A multicenter randomized controlled trial enrolled patients aged 65 or older referred to a 3-week balneotherapy program, and screened for risk of falling (a history of falls in the last year and a timed up and go test or a five chair rising test >12 sec or a 4-meter walk test >4 sec). In addition to balneotherapy, patients had either no intervention (controls) or twelve 60-minute sessions of physical activity including 15 minutes of health education and three 90-minute sessions of an educational program (intervention).

Results: There were 118 control and 105 intervention patients. The balneotherapy program alone had a clinically significant effect on (i) the grip strength, (ii) the five chair rising test, (iii) the 4-meter walk test, and (iv) the short physical performance battery (Cohen's d 0.29-0.46). It had no effect on (i) the maximum time stood on one foot, and (ii) the timed up and go test. Furthermore, it worsened the falls efficacy scale (d = 0.27). Adding a physical activity and educational program significantly improved (i) the time stood on one foot (Cohen's d =-0.34), and (ii) the timed up and go test (d=- 0.44), (iii) and reduced the concern about falling (Falls Efficacy scale, d=-0.25), and (iv) the fear of falling (d=-0.34).

Conclusion: Older patients referred to a balneotherapy program and at high risk of falling when screened at the entrance of the center should be offered an additional physical and educational program to further improve the functional effects of balneotherapy on the timed up and go test, balance, and the fear of falling.

Purpose: With the increasing aging of the population and the increasing incidence of chronic diseases in China, home hospice care services can meet the desire of the older adult with chronic diseases to receive care and die at home. In order to ensure the real application of hospice in families, the goal of the study was to construct a home hospice care program for the older adult at the end of life with chronic diseases based on Harmony Nursing Theory (composed of three parts: harmony needs assessment, harmony mechanism establishment and interpersonal interaction).

Methods: Through literature review, a qualitative interview and group discussion, the first draft of a home hospice care program for the older adult at the end of life with chronic diseases based on the harmony nursing theory was developed, which was further revised and finalized by combining the Delphi method of expert correspondence with 19 experts and a pilot study with a home hospice care team.

Results: A total of two rounds of expert correspondence were conducted. In the first round, 21 questionnaires were distributed and 19 were returned, yielding a recovery rate of 90.48%. In the second round, 19 questionnaires were distributed, and 19 questionnaires were collected. The recovery rate was 100%. The authority of the two rounds of expert correspondence was 0.96, and Kendall's coefficient of concordance (W) was 0.268 and 0.310, respectively. After the first round of Delphi expert consultation, 3 items were deleted, and 12 items were revised. In the second round of Delphi expert consultation, two items were revised. The final version of the home hospice program includes 4 first-level items, 20 second-level items, and 59 third-level items.

Conclusion: The home hospice care program based on harmony nursing theory is authoritative and scientific and can provide a reference for the practice of home hospice care for the older adult with chronic diseases.

Objective: To compare the differences in risk factors and etiological classification between cerebral infarction in young patients and elderly patients, and explore the correlation between cerebral infarction in young patients and white matter lesions (WMLs).

Methods: Sixty young patients with cerebral infarction and 142 elderly patients with cerebral infarction were included. The distributions of risk factors such as hypertension, diabetes, heart disease, smoking status, alcohol consumption status, migraine status, and WMLs in the two groups were carefully investigated and statistically analyzed.

Results: According to the univariate analysis, the proportions of males, obese patients, patients with migraine, and patients with obstructive sleep apnea-hypopnea syndrome (OSAHS) in the young group were significantly greater than those in the elderly group. Hypertension, heart disease, and hyperhomocysteinemia were significantly more common in the elderly group than in the young group. According to the TOAST classification, the incidence of stroke of undetermined etiology in the young group was greater than that in the elderly group, whereas the incidence of large-artery atherosclerosis (LAA) in the elderly group was greater than that in the young group. Binary logistic regression analysis revealed that male sex, migraine status, and obstructive sleep apnea-hypopnea syndrome were independently associated with cerebral infarction in young adults, whereas hypertension, heart disease, and hyperhomocysteinemia were independently related to cerebral infarction in elderly individuals. In addition, the incidence of WMLs in the migraine group of young cerebral infarction patients was significantly greater than that in the nonmigraine group.

Conclusion: Compared with those in elderly patients with cerebral infarction, the risk factors for cerebral infarction in young patients are relatively controllable. Furthermore, more methods are needed to determine the etiology of unexplained cerebral infarction in young patients. WMLs are thought to have a relatively high incidence in young patients with cerebral infarction and are significantly associated with migraine.

Background: Neutrophil-to-lymphocyte ratio (NLR) and Lymphocyte-to-monocyte ratio (LMR) have been reported to be associated with outcomes in acute ischemic stroke. However, research on elderly populations remains relatively scarce. We investigated the prognosis of NLR and LMR in elderly with acute ischemic stroke(AIS).

Methods: Based on the modified Rankin Score (mRS) on the 90th day after stroke, patients were divided into group and bad prognosis groups. Multivariate logistic regression analysis and receiver operating curves were used to identify prognostic factors and their predictive powers.

Results: In total, 824 elderly patients with AIS were enrolled between November 2021 and December 2023. Significant differences emerged in the NLR, LMR, and lymphocyte count between the two groups (P<0.05). Binary logistic regression identified NLR, LMR and neutrophil count as independent risk factors for an unfavorable prognosis in elderly patients with AIS. The areas under the curve (AUCs) of NLR, LMR, and the combination of NLR and LMR to discriminate poor function prognosis were 0.703, 0.672, and 0.706, respectively. ROC analysis also showed that combination of NLR and LMR was superior to NLR and LMR alone for predicting AIS.

Conclusion: NLR and LMR independently contribute to an unfavorable prognosis in elderly patients with AIS. The area under the ROC curve (AUC) for the combined NLR and LMR was higher than that for NLR and LMR individually, suggesting that combining these two indicators can improve the predictive ability for clinical outcomes in elderly patients with AIS.

Background: Cardiovascular disease (CVD) has become the leading cause of death worldwide. High muscle mass can reduce the incidence and mortality of CVD. In recent years, increasing attention has been given to the relationship between intrinsic capacity (IC) and CVD. This study aims to explore the relationship between the decline of IC, muscle strength, and muscle quality in older patients with CVD, providing a new method and basis for early recognition of IC decline in the older adults.

Methods: This cross-sectional study included 475 older individuals from communities in Zhejiang. General data were collected, and a comprehensive geriatric assessment (CGA) was conducted. Participants with CVD were divided into three groups: IC retention, IC impairment, and IC significantly impaired. Bioelectrical impedance analysis (BIA) measurements were completed. Student's t-test or non-parametric tests (Mann-Whitney) were used to analyze the correlation between IC and muscle-related indicators. The best cutoff values were obtained using ROC curve analysis.

Results: Compared to non-CVD patients, CVD patients were older, more educated, and had higher rates of polypharmacy and comorbidity. IC decreased more significantly in CVD patients. Age (P=0.001), Fried (P=0.024), and GDS-5 (P=0.002) increased with the severity of IC decline. ADL (P=0.002), MMSE (P=0.000), MNA-SF (P=0.000), SARC-Calf (P=0.026), waist circumference (P=0.037), and muscle quality (P=0.010) decreased with the decline in IC. When IC decreased, the cutoff values for hand grip strength, waist circumference, and muscle quality were 25.45 kg, 72.55 cm, and 3.05, respectively. When IC decreased significantly, the cutoff values were 17.15 kg, 71.55 cm, and 2.28, respectively.

Conclusion: The results of this study showed that in patients with CVD, the hand grip strength and muscle quality of patients with IC injury were lower than those of patients with IC retention.
