The Helmholtz resonance acoustic metamaterial is an effective sound absorber in the field of noise reduction, especially low-frequency domain. To overcome conflict between number resonators and volume rear cavity for each chamber with a given front area single-layer metamaterial, novel interlayer parallel connection multiple (IPC–MHR) proposed this study. developed IPC–MHR consists several layers, among different layers are connected parallel. absorption property studied by finite element...

Previous studies have linked self-management with social support and family function. However, little is known about the mechanisms underlying these relationships. This study aimed to explore relationships between (family function) examine whether well-being mediated in elderly patients hypertension. A cross-sectional design was used 517 Demographics, behaviors, support, function were collected by questionnaires. Results showed that separately associated behaviors. When included regression...

Self-management is crucial for blood pressure control and subsequent disease prevention. Health literacy acceptance of illness may contribute to self-management behaviour; in addition, mediate the effects health on behaviour among patients with hypertension.The aims research were examine whether associated both pharmacological non-pharmacological management possible mediating hypertension.Hierarchical regression analysis was conducted analyse relationships between literacy, illness,...

Abstract Background Somatic symptoms and related factors in patients with chronic heart failure have been extensively researched. However, more insight into the complex interconnections among these constructs is needed, as most studies focus on them independently from each other. Aims The aim of this study to gain a comprehensive understanding how somatic are interconnected failure. Methods A total 379 were enrolled. Network analysis was used explore risk factors. Results four core daytime...

Abstract Aim Although sleep duration and weight-adjusted waist index (WWI) are recognized CVD risk factors in older adults, the individual dual trajectories of these their associations with remain unclear. We aim to investigate using data from Chinese Longitudinal Healthy Longevity Survey (CLHLS). Methods results included 3,313 adults without hypertension, heart disease, or stroke 2011 assessed duration, WWI, incidence 2011, 2014, 2018. Group-based trajectory modeling logistic regression...

Background: The hypertension control rate in China is much lower than that developed countries. Self-management among elderly patients with can improve blood pressure control; thus, it necessary to explore its association individual and social environmental factors. Objective: Our objective was investigate self-management factors based on the ecological model. Methods: A total of 301 were recruited do a questionnaire survey model, which included General Demographic Information Questionnaire,...

Abstract Background The instrumental activities of daily living (IADL) among the elderly have been found to be heterogeneous, with different trajectories. However, transition IADL over time remains unclear. We aimed explore probabilities and predictors elderly. Methods Longitudinal data from 2014 (T1) 2018 (T2) waves Chinese Healthy Longevity Survey were extracted. A sample 2,944 participants aged 65 years or older, complete responses scale, was included. Latent profile analysis (LPA) latent...

Abstract Aims This study aimed to uncover hidden patterns and predictors of symptom multi-trajectories within 30 days after discharge in patients with heart failure assess the risk unplanned 30-day hospital readmission different patterns. Methods results The was conducted from September 2022 2023 four third-class hospitals Tianjin, China. A total 301 were enrolled cohort, 248 completed a follow-up discharge. Three multi-trajectory groups identified: mild status (24.19%), moderate (57.26%),...

Background Previous research has examined the dyadic health components consisting of burdens, psychological disorders, resilience, and illness- or caregiving-related beliefs independently from each other in patients with chronic heart failure (CHF) their caregivers, but there is a need for further insights into interconnections. Objective We aimed to explore interconnections among CHF caregivers. Methods conducted cross-sectional study, recruiting total 355 respective totaling 710...

Metabolic syndrome has become a significant public health concern. This study aims to investigate the impact of dietary patterns on metabolic in young adults and how physical activity modulates this effect. A cross-sectional was conducted at management center Tianjin, China, from September 2022 March 2023. Participants aged 18-35 years were recruited using convenience sampling. Dietary intake assessed validated food frequency questionnaire. Logistic regression models evaluated associations...

This research investigated the effectiveness of caregiver-mediated online dignity therapy in enhancing dyadic health and family function.Heart failure (HF) dyads were recruited between May December 2021 from a university-affiliated hospital China. The (N=70) randomly allocated to intervention group control group. We assessed patients' outcomes (hope, well-being, Family APGAR Index quality life (QoL)) their caregivers' (anxiety, depression Index) at baseline (T0), 1 week (T1), 4 weeks (T2) 8...

Caregiver self-efficacy is crucial in improving patient outcomes and caregiver well-being, but there a lack of suitable scales to assess this concept within the context Chinese culture. This study aimed cross-culturally translate Self-Efficacy Contributing Patient Self-Care (CSE-CSC) Scale evaluate its psychometric properties using classical test theory item response theory.

Background Although a growing number of studies have demonstrated that patients' health literacy is associated with outcomes, the exact relationship between them not clear. Aims and objectives The aim this study was to explore latent classes in patients heart failure analyze differences among different groups. Design Methods This cross-sectional survey. Patients diagnosed were selected from 3 tertiary hospitals Tianjin, China, March 2019 November 2019. We measured using Health Literacy Scale...

Background The concept of perceived control reflects the belief that one has resources needed to cope with negative events and ability positively influence consequences those events. In patients heart failure, is associated a variety health outcomes. Perceived commonly measured using Control Attitudes Scale-Revised (CASR). There no Chinese version CAS-R (CCAS-R). Objective purpose this article was perform linguistic validation psychometric evaluation CCAS-R. Methods translated into according...
