Socio-ecological model as a framework to understand the low participation of Earth Hour among Chinese college students: conflict between belief and practice.

Earth Hour, a global mass effort coordinated to show concern for green urban construction and sustainable development, was first organized by the World Wildlife Fund in Australia in 2007 with a growing trend of participation worldwide. However, analysis of participation in Earth Hour based on a large population are sparse, with only a few studies reporting details in positive results without a clear pattern that explains the potential low participation. This study focuses on the non-participants and analyzed the reasons for low participation in Earth Hour using a questionnaire with 401 college students based on the socio-ecological model.

Arterial stiffness in adults with steady-state bronchiectasis: association with clinical indices and disease severity.

Background: Cardiovascular disease are common co-morbidities in bronchiectasis and contribute substantially to disease burden and mortality. Brachial-ankle pulse wave velocity (baPWV), a measure of arterial stiffness, has a strong predictive value for cardiovascular event. We hypothesized that baPWV would be increased in steady-state bronchiectasis patients, and correlates with the degree of systemic inflammation and disease severity assessed with Bronchiectasis Severity Index and FACED scores.

Subclinical atherosclerosis in adults with steady-state bronchiectasis: A case-control study.

Background And Objective: Bronchiectasis has been associated with increased risks of cardiovascular disease, in which early-stage endothelial dysfunction might have played pivotal roles. We aimed to investigate endothelial function in bronchiectasis patients, by measuring flow-mediated dilatation (FMD) and carotid intima-media thickness (CIMT) as compared with control subjects, and to elucidate the impact of different risk factors on subclinical atherosclerosis.

Methods: The study included 80 bronchiectasis patients and 80 age- and sex-matched healthy subjects.

Subclinical atherosclerosis risk markers in patients with chronic obstructive pulmonary disease: A systematic review and meta-analysis.

Background And Aims: Chronic obstructive pulmonary disease (COPD) is associated with increased cardiovascular morbidity and mortality. Identifying early changes of cardiovascular system before the occurrence of fatal clinical event is critical for the management of COPD. We performed a meta-analysis to investigate the associations between COPD and subclinical markers of cardiovascular risk.
