The impact of social support on benefit finding among patients with advanced lung cancer and their caregivers: based on actor-partner interdependence mediation model.

PURPOSE: Advanced lung cancer and its treatment serve as a sudden stressful event that profoundly impacts the psychological experience of both the patients and their primary caregiver. This study used dyadic analyses to explore the dyadic effects of social support on benefit finding and whether hope level mediates the patient-caregiver dyads in advanced lung cancer. METHODS: Two hundred ninety-five pairs of patients with advanced lung cancer and primary caregivers completed the Social Support Rating Scale (SSRS), the Herth Hope Index (HHI), and the Benefit Finding Scale (BFS). Dyadic analyses were conducted using structural equation modelling based on the actor-partner interdependence mediation model. RESULTS: The results indicated that for both patients (B = 0.259, 95% CI = 0.135-0.423, P < 0.001) and their primary caregivers (B = 0.596, 95% CI = 0.403-0.838, P < 0.001), hope level mediated the actor effect of social support on benefit finding; social support was positively associated with hope level and further enhanced benefit finding. Regarding partner effects (B = 0.242, 95% CI = 0.119-0.404, P < 0.001), primary caregivers' social support significantly indirectly affected patients' benefit finding through patients' hope level. CONCLUSION: There is an interaction between social support, hope level, and benefit finding in patients with advanced lung cancer and their primary caregivers. Healthcare professionals ought to be vigilant in recognizing patients and caregivers who are vulnerable, have limited social support, and possess diminished hope levels. At the same time, nurses should provide timely psychological support and counseling to patients and their caregivers, encourage them to actively participate in social activities, and inspire their confidence and hope in life, thus improving their benefit findings.

Type 2 diabetes and inflammatory bowel disease: a bidirectional two-sample Mendelian randomization study.

To investigate the association between T2DM and IBD by bidirectional two-sample Mendelian randomization (MR) to clarify the casual relationship. Independent genetic variants for T2DM and IBD were selected as instruments from published genome-wide association studies (GWAS), mainly in European ancestry. Instrumental variables (IVs) associated with T2DM and IBD were extracted separately from the largest GWAS meta-analysis. MR analyses included inverse variance weighting, weighted median estimator, MR Egger regression, and sensitivity analyses with Steiger filtering and MR PRESSO. In the data samples for Ulcerative colitis (UC) (6968 cases, 20,464 controls) and Crohn's disease (CD) (5956 cases, 14,927 controls), there was a negative causal relationship between T2DM and UC [IVW, OR/95%CI: 0.882/(0.826,0.942), p < 0.001]. However, the causal relationships between T2DM and CD, UC and T2DM, CD and T2DM were not significant, and the p value measured by the IVW method was ≥ 0.05. All SNPs showed no significant horizontal pleiotropy (p > 0.05). The results of the bidirectional MR Study suggest that T2DM has a negative causal effect on UC, which provides implications for clinical treatment decisions in IBD patients with T2DM. The findings do not support a causal relationship between T2DM and CD, UC and T2DM, or CD and T2DM, and the impact of IBD on T2DM needs further investigation.

The Mediating Effect of Hope Level Between Social Support and Benefit Finding in Patients With Advanced Lung Cancer.

BACKGROUND: As a protective factor, social support can influence benefit finding (BF) in patients with advanced lung cancer. However, the mechanism through which social support affects BF is controversial. OBJECTIVE: To investigate the factors influencing BF in patients with advanced lung cancer and the role of hope level in mediating the relationship between social support and BF. METHODS: This was a cross-sectional study. From September 2022 to March 2023, 286 participants completed the Social Support Rating Scale, Herth Hope Index, and Benefit Finding Scale. Data analysis included correlation analyses and multiple stepwise regression analysis; the SPSS PROCESS program was used to determine the significance of mediating effects. RESULTS: Social support and hope level were positively associated with BF. Monthly per-capita household income, social support and hope level entered the final regression model and explained 50.7% of BF variance. Social support's direct and indirect effects on BF were significant (P < .05), suggesting that hope level partially mediated the relationship between social support and BF. CONCLUSION: Our findings validate a positive association between social support and BF in patients with advanced lung cancer. The hope level as a mediating variable provided the impetus for their BF. IMPLICATIONS FOR PRACTICE: Nurses should implement necessary interventions to help patients with advanced lung cancer carry out protective resources and coping strategies to facilitate their BF.
