Abstract

Introduction Patients on hemodialysis exhibit a heightened propensity for both falls and fractures compared with their healthier counterparts. (1) The susceptibility of patients on hemodialysis to frailty and sarcopenia surpasses [...], Objective. Patients on hemodialysis are highly susceptible to falls and fractures. Amplified apprehension regarding the fear of falling (FOF) constitutes a risk factor that restricts physical activity and escalates the probability of falls among the elderly population. This study aimed to elucidate the association between falls and FOF and physical activity in patients on hemodialysis. Methods. A prospective cohort study was conducted across 9 centers. FOF was assessed using the Falls Efficacy Scale-International (FES-I). Physical activity was assessed using the Japanese version of the International Physical Activity Questionnaire short form. Subsequently, falls were monitored over a duration of 1 year. Logistic regression analysis was performed to evaluate the relationship between falls and FOF and physical activity. In addition, in the receiver operating characteristic analysis, the cutoff value of FES-I that predicts falls was determined using the Youden Index. A restricted cubic spline curve was utilized to analyze the nonlinear association between falls and the FES-I. Results. A total of 253 patients on hemodialysis (70.0 [59.0-77.0] years old; 105 female [41.5%]) were included in the analysis. During the 1-year observation period, 90 (35.6%) patients experienced accidental falls. The median FES-I score was 36.0 (24.0-47.0) points, and patients with higher FES-I scores had more falls. Following adjusted logistic regression analysis, FES-I exhibited an independent association with falls (OR = 1.04; 95% CI = 1.01 -1.06), but physical activity was not. The area under the receiver operating characteristic curve was 0.70 (95% CI = 0.64-0.77), and the FES-I threshold value for distinguishing fallers from non-fallers was determined as 37.5 points (sensitivity 65.6%, specificity 35.0%). A nonlinear relationship between falls and FES-I was observed. Conclusion. FOF was associated with the incidence of falls in patients on hemodialysis. Impact. The evaluation and implementation of interventions targeting the FOF may mitigate the risk of falls. Keywords: Falls, Fear of Falling, Hemodialysis, Physical Activity, Physical Function

Abstract

Aim: Circulating blood volume (BV) during exercise changes depending on the intensity and duration, and post‐exercise hypotension is observed after continuous exercise. We investigated the safety and efficacy of both interval and continuous IDE at anaerobic threshold (AT) levels with respect to hemodynamic stability and dialysis efficiency. Methods: In this crossover randomized controlled trial, 16 patients on haemodialysis were subjected to three trial arms, including non‐IDE, interval‐IDE, and continuous‐IDE arms. Systolic blood pressure (SBP), BV, and ultraviolet absorbance – an indicator of dialysis efficiency – were continuously measured, and each change was compared between the three arms by two‐way analysis of variance. Results: Continuous IDE decreased SBP from post‐exercise to the end of dialysis compared with baseline (pre 142.8 ± 19.0 vs. post 127.5 ± 24.5 mmHg, p =.02), whereas interval IDE maintained better SBP levels post‐exercise (pre 139.9 ± 17.1 vs. post 140.1 ± 15.8 mmHg, p = 1.0) than continuous IDE (non‐IDE 133.2 ± 19.9 vs. interval 140.1 ± 15.8 vs. continuous 127.5 ± 24.5 mmHg, p =.04). Moreover, interval IDE caused less tiredness and few symptoms (p <.05), despite reaching higher intensity than continuous IDE (p =.001). The BV of each IDE arm decreased during exercise and recovered post‐exercise to the same level as non‐IDE. Ultraviolet absorbance was not different between each arm (p =.16). Conclusion: AT‐level interval IDE maintains better hemodynamic stability from post‐exercise to the end of dialysis and may represent a novel approach that can be effectively performed with fewer symptoms.

Abstract

Two-point discrimination (2PD) test ref lects somatosensory spatial discrimination ability, but evidence on the relationship between 2PD and cortical gray matter (GM) volume is limited. This study aimed to analyze the relationship between cortical GM volume and 2PD threshold in young healthy individuals and to clarify the characteristics of brain structure ref lecting the individual differences in somatosensory function. 2PD was measured in 42 healthy (20 females) volunteers aged 20–32 years using a custom-made test system that can be controlled by a personal computer. The 2PD of the right index finger measured with this device has been confirmed to show good reproducibility. T1-weighted images were acquired using a 3-T magnetic resonance imaging scanner for voxel-based morphometry analysis. The mean 2PD threshold was 2.58 ± 0.54 mm. Whole-brain multiple regression analysis of the relationship between 2PD and GM volume showed that a lower 2PD threshold (i.e. better somatosensory function) significantly correlated with decreased GM volume from the middle temporal gyrus to the inferior parietal lobule (IPL) in the contralateral hemisphere. In conclusion, a lower GM volume in the middle temporal gyrus and IPL correlates with better somatosensory function. Thus, cortical GM volume may be a biomarker of somatosensory function.

Abstract

Background In hemodialysis patients, high body mass index is associated with low mortality while abdominal obesity relates to increased mortality. We aimed to investigate the association between muscle mass, intramuscular fat and abdominal fat measured by abdominal computed tomography (CT), and mortality in this patients population. Methods This two-center retrospective cohort study included hemodialysis patients who underwent abdominal CT between January 2013 and December 2018. Skeletal muscle mass index (SMI), muscle radiation attenuation (MRA) as an index of intramuscular fat, and visceral fat to subcutaneous fat ratio (VSR) were calculated using CT images at the third lumbar vertebral level. Multivariate Cox proportional hazards model was used to determine the independent predictors of all-cause, cardiovascular and non-cardiovascular mortalities. Results The study included 344 patients (median age 71.0 years; female 33.7%), among whom 145 died during a median follow-up of 4.9 years—46 and 99 from cardiovascular and non-cardiovascular causes, respectively. Lower MRA [hazard ratio (HR) 0.71, 95% confidence interval (CI) 0.58–0.87, P  = .001] and higher VSR (HR 1.17, 95% CI 1.01–1.37, P  = .04) were independently associated with higher all-cause mortality but not with lower SMI (HR 0.87, 95% CI 0.68–1.11, P  = .26). Lower MRA (HR 0.51, 95% CI 0.35–0.73, P  < .001) and higher VSR (HR 1.29, 95% CI 1.09–1.54, P  = .003) were also associated with cardiovascular and non-cardiovascular mortality, respectively. Conclusions Intramuscular fat and abdominal fat as measured using abdominal CT in hemodialysis patients are stronger independent predictors of mortality than muscle mass. [ABSTRACT FROM AUTHOR]
