Dyadic Associations Between Burden and Depressive Symptoms Among Patients With Heart Failure and Their Caregivers: The Mediating Role of Perceived Stress.

Background: Depressive symptoms are prevalent in patients with heart failure and their family caregivers. Given the interpersonal interactions between dyadic individuals with intimate relationship, it is essential to consider the dyads as a unit when exploring the factors associated with depressive symptoms in heart failure patient-caregiver dyads.

Objective: The aims of this study were to explore the dyadic effects of burden on depressive symptoms in heart failure patient-caregiver dyads and investigate whether perceived stress acts as a mediator in these relationships.

Association between nut consumption and mortality among Chinese older people: A national cohort study based on CLHLS from 2008 to 2018.

Background: Few quantitative studies have explored the associations between nut consumption and better health outcomes among a national cohort of community-dwelling older Chinese people. Given the need for more evidence to support the health benefits of nuts among Chinese people, we investigated whether nut consumption was associated with subsequent 10-year mortality.

Methods: We analyzed data from the Chinese Longitudinal Healthy Longevity Survey.

Serial multiple mediators in the relationship between symptom burden and sleep quality among patients with heart failure.

Background: Sleep disturbance is common in patients with heart failure. The aims of this study were to assess the prevalence of sleep disturbance in patients with heart failure, and to examine the serial multiple mediation effects of psychological distress and sleep hygiene practices on the relationship between symptom burden and sleep quality.

Methods: We recruited eligible heart failure patients in a large, university-affiliated hospital in Shandong Province, China, from November 2018 to June 2019.
