AI Article Synopsis
- The study aimed to explore the link between health-related quality of life (HRQoL) and muscle strength in patients on maintenance hemodialysis (MHD).
- Conducted in China, 110 MHD patients were evaluated for their HRQoL using the SF-36 survey and muscle strength through handgrip strength measures.
- Findings indicated that higher handgrip strength correlated with better physical health scores, suggesting that improving muscle strength might enhance HRQoL for MHD patients, especially regarding their physical health.
Article Abstract
Objective: We aimed to identify the association between Health-related quality of life (HRQoL) and muscle strength in patients undergoing maintenance hemodialysis (MHD).
Methods: In this cross-sectional study from March 2021 to December 2021, 110 MHD patients with a mean age of 63.9 ± 13.0 years and a median dialysis vintage of 25.5 (12.0-52.3) months, were enrolled at a hemodialysis center in Guangzhou city, China. HRQoL was assessed using the Short Form 36 Health Survey (SF-36) and converted into the Physical Component Summary (PCS) and the Mental Component Summary (MCS). The groups were assigned according to the mean score of PCS and MCS, and those with higher PCS/MCS scores (high-PCS/MCS) were compared with those with lower PCS/MCS scores (low-PCS/MCS). Independent factors were evaluated using multivariate analysis. Muscle strength was estimated by handgrip strength (HGS).
Results: The mean HGS was 23.7 ± 9.60 kg in men and 14.3 ± 5.30 kg in women. Compared to the high-PCS group, the low-PCS group had older age, higher levels of creatinine, total cholesterol, high-sensitivity C-reactive protein (hsCRP) and interleukin-6 (IL-6), and had lower HGS (all < 0.05). After adjusting for confounding factors in different models, the five-model multivariate binary logistic regression analyses revealed that HGS was the only independent factor in PCS domain, but not in MCS.
Conclusion: HGS may be an independent factor of poor HRQoL in MHD patients, particularly in relation to physical health. The management of muscle strength may improve the HRQoL in MHD patients.

Granulomatosis with polyangiitis (GPA) is a systemic vasculitis that can lead to persistent pain and fatigue, significantly impacting patients' quality of life. This study assessed the effects of transcranial direct current stimulation (tDCS) combined with aerobic exercise as a non-pharmacological intervention for managing fatigue in GPA patients. Two patients were randomly assigned to receive either active tDCS or simulated tDCS stimulation (sham) during low-intensity aerobic exercise.

Introduction: The retinal nerve fiber layer (RNFL) or ganglion cell-inner plexiform layer (GC-IPL) is associated with cognitive impairment. However, the relationship between retinal asymmetry and cognitive frailty (CF) remains unknown.
Methods: Two hundred twenty-two community-dwelling older adults were assessed starting in 2015 and underwent biennial cognitive and frailty evaluations until 2022.

Background: Poor sleep quality may contribute to sarcopenia, but evidence remains sparse. This retrospective cross-sectional study investigated the association between subjective sleep quality and probable sarcopenia in a cohort of community-dwelling older adults enrolled in the Longevity Check-Up 8+ study.
Methods: Participants were asked about their sleep quality over the past month, with four possible options ("very good", "quite good", "quite bad", very bad").
