Article Abstract

Objectives: Our research intended to explore the association and mediators (perceived social support and sleep quality) between the impact of oral health-related quality of life (OHRQoL) and depression among Chinese older adults.

Methods: A stratified, multi-stage random sampling approach was used in our study. A total of 3896 older individuals aged 60 years and older were included. Process macro 3.5 for SPSS was utilized for testing mediation hypotheses.

Results: The mean score of the OHRQoL of the elderly was 3.26 ± 7.15. The correlation coefficient between OHRQoL and depression was 0.25 (p < 0.001). Perceived social support (β = 0.009, 95% CI = 0.006, 0.012) and sleep quality (β = 0.073, 95% CI = 0.074, 0.093) mediated the relationship between OHRQoL and depression, respectively. The association between OHRQoL and depression was mediated sequentially by perceived social support and sleep quality (β = 0.004, 95% CI = 0.002, 0.006).

Conclusions: The participants reported relatively good OHRQoL. OHRQoL and depression showed a significant positive correlation. The relationship between OHRQoL and depression among Chinese seniors was mediated by perceived social support and sleep quality. Both directly and indirectly, OHRQoL can affect depression.

The widespread use of social media has led to growing concerns about its impact on mental health. As digital dependency rises, the Joy of Missing Out (JOMO) has emerged as a potential means to help individuals find satisfaction in offline activities and reduce social media addiction. This study examines the serial mediating role of loneliness and psychological distress in the relationship between JOMO and social media addiction while also validating the JOMO scale's psychometric properties.

Monoclonal gammopathy-associated myopathies (MGAMs) are rare yet treatable myopathies that occur in association with monoclonal gammopathies. These myopathies include light chain (AL) amyloidosis myopathy, sporadic late-onset nemaline myopathy (SLONM), scleromyxedema with associated myopathy, and newly reported monoclonal gammopathy-associated glycogen storage myopathy (MGGSM), including the vacuolar myopathy with monoclonal gammopathy and stiffness. All these 4 distinct subtypes of MGAMs typically present in patients aged 40 or older, frequently with a subacute onset of rapidly progressive proximal and axial muscle weakness.

Introduction: Co-morbid insomnia and sleep apnea (COMISA) has been linked to poorer health outcomes and increased all-cause mortality compared with either insomnia or obstructive sleep apnea (OSA) alone.

Materials And Methods: We investigated the relationship between COMISA and uncontrolled hypertension in the Swedish CardioPulmonary BioImage Study (SCAPIS). A cross-sectional analysis including participants from the SCAPIS Gothenburg cohort (n=3832, 46% males, age 57.

Background: Coronary atherosclerosis is a leading cause of cardiovascular disease and death worldwide. Despite progress in understanding its pathogenesis, the roles of circulating inflammatory proteins and plasma metabolites are complex and not fully elucidated. Existing Mendelian randomization (MR) studies often target isolated biomarkers, lacking comprehensive and mechanistic insights.

Emphysema is characterized by chronic alveolar destruction. Lipofibroblasts (LIF) are crucial in the stem cell niche surrounding alveolar type II (AT2) cells and may contribute to alveolar regeneration. We aim to determine whether emphysema is associated with LIF reduction and whether Sterol regulatory binding protein (SREBP) activation promotes LIF differentiation and fibroblast stem cell niche properties.
