Investigation of optimum hemoglobin levels in older patients with chronic kidney disease

Prevalence and risk factors of falls in people on hemodialysis: a systematic review and meta-analysis

OBJECTIVES

This study aims to systematically quantify the prevalence of falls in people on hemodialysis and to assess risk factors associated with falls by synthesizing emerging best evidence.

METHODS

A comprehensive search was conducted across ten databases from their inception to February 27, 2025. The research team independently conducted study selection, quality assessments, data extraction, and analyses of all included studies. Meta-analysis was performed using random-effects and fixed-effects models. The PRISMA guidelines were used to report the systematic review and meta-analysis.

RESULTS

A total of 31 studies, comprising 191,800 individuals, were included in the analysis. The pooled prevalence of falls in people on hemodialysis was 27.1%. The meta-analysis of risk factors included 19 studies. After controlling for confounding variables, 12 risk factors were associated with falls, including older age, female gender, longer dialysis duration, diabetes mellitus, peripheral vascular disease, paralysis, antidepressant use, frailty, use of walking aids, malnutrition, intradialytic hypotension, and low hemoglobin levels.

CONCLUSIONS

This study provides an updated, evidence-based assessment of the prevalence and risk factors of falls in people on hemodialysis, confirming their multifactorial etiology. Screening and interventions should be implemented promptly to mitigate the adverse outcomes of falls in people on hemodialysis.

Correlation between vascular access satisfaction and demoralization syndrome in elderly patients with maintenance hemodialysis: a multi-center study

OBJECTIVE

This multi-center study aimed to investigate the correlation between vascular access satisfaction (VAS) and demoralization syndrome (DS) in elderly patients undergoing maintenance hemodialysis (MHD). Secondary objectives included identifying predictors of VAS and comparing DS severity between patients with high and low VAS scores.

METHODS

A retrospective analysis was conducted from April 2024 to October 2024, involving 350 elderly MHD patients from three tertiary hospitals in China. Participants were stratified into two groups based on VAS scores: the VA dissatisfaction group (n = 220) and the VA satisfaction group (n = 130). Data collection utilized the Short Form Vascular Access Questionnaire (VAQ) and the Chinese Version of the Demoralization Syndrome Scale. Binary logistic regression and independent t-tests were employed to analyze predictors of VAS and DS scores.

RESULTS

Significant differences in VAS scores were observed between the dissatisfaction and satisfaction groups (p < 0.001). Multivariate analysis identified living alone (OR = 2.1, 95% CI 1.4-3.2), prolonged dialysis duration (OR = 1.8, 95% CI 1.2-2.7), and elevated parathyroid hormone (PTH) levels (OR = 1.5, 95% CI 1.1-2.0) as independent risk factors for VAS, while higher hemoglobin levels (OR = 0.6, 95% CI 0.4-0.9) served as a protective factor. Notably, the dissatisfaction group exhibited markedly higher DS scores (73.6 ± 8.7 vs. 51.2 ± 6.9, p < 0.01), indicating a strong association between VAS and psychological distress.

CONCLUSION

This study underscores a robust correlation between VAS and DS in elderly MHD patients. Interventions targeting social support optimization, anemia management, and mineral metabolism regulation may improve vascular access outcomes and mitigate demoralization, thereby enhancing quality of life.

Clinical implication of anemia in older patients with dementia with lewy bodies

AIM

This research sought to investigate the possible connection between anemia and various parameters of comprehensive geriatric assessment in elderly individuals diagnosed with Dementia with Lewy Bodies (DLB). To our knowledge, this investigation represents the first attempt to examine how anemia impacts patients suffering from DLB.

METHODS

This cross-sectional study encompassed 147 DLB patients from a single geriatric outpatient clinic. The study defined anemia as hemoglobin levels under 12 g/dL for women and 13 g/dL for men. Patients' demographic information, coexisting medical conditions, and results from comprehensive geriatric evaluations were also recorded.

RESULTS

Participants in the study had an average age of 85.4 ± 7.1 years. Anemia was present in 46.9% of the patients. Significant disparities were noted between individuals with and without anemia regarding the occurrence of congestive heart failure (CHF), polypharmacy, geriatric depression, and insomnia (all p < 0.05). After controlling for age, gender, and CHF in the multivariate analysis, the association between anemia and both the quantity of medications used [OR: 1.15 (95% CI:1.01-1,31)] and Geriatric Depression Scale-15 scores [OR: 0.88, 95% CI: 0.78-0.98] remained statistically significant (p < 0.05) when comparing anemic patients to non-anemic individuals.

CONCLUSION

In the present study almost one in two older patients with DLB were anemic. Anemia is associated with presence of CHF, higher number of drugs and depressive mood in DLB. It is recommended that healthcare providers should recognize the importance of anemia and its associated effects when treating older adults with DLB. This approach may lead to more effective management and treatment of this complex condition.

The connection between anemia and limitations in daily activities among older males: the critical role of dynapenia

AIM

The aim of the present study was to examine the relationship between anemia and basic and instrumental activities of daily living in older male patients.

METHODS

A total of 223 older males attending one geriatric outpatient clinic were included in this cross-sectional study. Anemia was defined as a hemoglobin level below 13 g/dL. Patients' demographic characteristics, comorbidities, and comprehensive geriatric assessment parameters were also recorded. Handgrip strength of < 27 kg for males was accepted as dynapenia. Basic Activities of Daily Living (BADL) and Instrumental Activities of Daily Living (IADL) questionnaires were used to evaluate functional capacity.

RESULTS

The mean age (standard deviation) of the participants was 80.17 (7.69) years. The prevalence of patients with anemia was 43.9%. There was differences between anemic and non-anemic groups in terms of presence of diabetes mellitus (DM), congestive heart failure (CHF), chronic kidney disease (CKD), malnutrition, dynapenia, geriatric depression, BADL and IADL scores (all p < 0.05). In multivariate analysis, after adjusting for all confounding variables except for dynapenia, patients with anemia were associated with reduced BADL and IADL (all p < 0.05). After adjusting for all confounding variables including dynapenia, deterioration in total BADL and IADL scores did not remain significant in the anemic group compared to the non-anemic group (p > 0.05).

CONCLUSION

Close to one in two older outpatient men had anemia. Anemic men had a higher incidence of DM, CHF, CKD, malnutrition, geriatric depression and dynapenia. Anemia was associated with dependence in both BADL and IADL in older men. However, comorbidities, nutritional status, depressive mood and, specifically muscle strength, were important contributors to this association.

Anaemia and quality of life in chronic kidney disease: a consensus document from the European Anaemia of CKD Alliance

Anaemia is common in chronic kidney disease (CKD) and has a significant impact on quality of life (QoL), work productivity and outcomes. Current management includes oral or intravenous iron and erythropoiesis-stimulating agents (ESAs), to which hypoxia-inducible factor prolyl hydroxylase inhibitors (HIF-PHIs) have been recently added, increasing the available therapeutic options. In randomised controlled trials, only intravenous iron improved cardiovascular outcome, while some ESAs were associated with increased adverse cardiovascular events. Despite therapeutic advances, several challenges and unmet needs remain in the current management of anaemia of CKD. In particular, clinical practice does not include an assessment of QoL, which prompted a group of European nephrologists and representatives of patient advocacy groups to revisit the current approach. In this consensus document, the authors propose a move towards a more holistic, personalised and long-term approach, based on existing evidence. The focus of treatment should be on improving QoL without increasing the risk of adverse cardiovascular events, and tailoring management strategies to the needs of the individual. In addition, the authors discuss the suitability of a currently available anaemia of CKD-specific health-related QoL measure for inclusion in the routine clinical management of anaemia of CKD. The authors also outline the logistics and challenges of incorporating such a measure into electronic health records and how it may be used to improve QoL for people with anaemia of CKD.

Clinical significance of hemoglobin level and blood transfusion therapy in elderly sepsis patients: A retrospective analysis

INTRODUCTION

The clinical significance of hemoglobin level and blood transfusion therapy in elderly sepsis patients remains controversial. The study investigated the relationship between mortality, hemoglobin levels, and blood transfusion in elderly sepsis patients.

METHODS

Elderly sepsis patients were included in the Marketplace for Medical Information in Intensive Care (MIMIC-IV) database. A multivariate regression model analyzed the relationship between the Hb level and the 28-day mortality risk. Logistic Multivariate analysis, Propensity Matching (PSM) analysis, an Inverse Probabilities Weighting (IPW) model and doubly robust estimation were applied to analyze the 28-day mortality risk between transfused and non-transfused patients in Hb at 7-8 g/dL, 8-9 g/dL, 9-10 g/dL, and 10-11 g/dL groups.

RESULTS

7473 elderly sepsis patients were enrolled in the study. The Hb level in the ICU and the 28-day mortality risk of patients with sepsis shared a non-linear relationship. The patients with Hb levels of <10 g/dL(p < 0.05) and > 15 g/dL(p < 0.05) within 24 h had a high mortality risk in multivariate analysis. In the Hb level 7-8 g/dL and 8-9 g/dL subgroup, the Multivariate analysis (p < 0.05), PSM (p < 0.05), IPW (p < 0.05) and doubly robust estimation (p < 0.05) suggested that blood transfusion could reduce the mortality risk. In the subgroup with a Hb level of 10-11 g/dL, IPW (p < 0.05) and doubly robust estimation (p < 0.05) suggested that blood transfusion could increase the mortality risk of elderly sepsis patients.

CONCLUSION

A non-linear relationship between the Hb level and the 28-day mortality risk and Hb levels of <10 g/dL and > 15 g/dL may increase the mortality risk, and blood transfusion with a Hb level of <9 g/dL may minimize mortality risk in elderly sepsis patients.

Impaired Activity of Daily Living Status of the Older Adults and Its Influencing Factors: A Cross-Sectional Study

This study aimed to explore the impaired activity of the daily living ability status and its influencing factors among older adults. A sample of 10,148 participants (≥60 years old) who met the requirements for the activity of daily living scale was used in this study, and the Health and Aging Tracking Survey was selected for data collection. The impaired activities of the daily living status of older adults and their influencing factors were analyzed by single-factor descriptive analysis and multi-factor logistic regression. The study results showed that the rate of impaired activities of the daily living ability of participants was 26.56%, among which the rate of mild impairment was 17.34% and severe impairment was 9.22%. Multi-factor binary logistic regression analysis results showed that demographic characteristics, lifestyle habits, and physical health status were associated with older adults' daily living activity ability. Among them, ages ≥80 years, male, habitual smoking, physical disability, and chronic diseases had a more significant impact.
