- This study describes coping strategies that patients with heart failure (HF) use to manage adverse drug events (ADEs). The included coping strategies were social support seeking, information seeking, non-adherence and taking alleviating medication. The role of beliefs about medication and ADE perceptions in explaining these coping strategies was assessed using the Self-Regulation Model. We performed a cross-sectional study including 250 HF patients who experienced an ADE. Patients completed validated questionnaires assessing their coping strategies, ADE perceptions and medication beliefs. Social support (60%) and information seeking (32%) were the most commonly used strategies to cope with ADEs. Non-adherence was reported by 7% of the patients. Multivariate linear regression analysis showed that demographics, clinical factors and medication beliefs explained only a small amount of the variance in coping strategies, whereas ADE perceptions explained a substantial amount of variance. Path analysis showed that patients' perceptions about the timeline, consequences and controllability of ADEs by the health care provider were directly related to their coping behaviour. The effect of patients' medication beliefs on their coping strategies was consistent with mediation through their ADE perceptions. Our results support the value of the Self-Regulation Model in understanding patients' coping behaviour with regard to ADEs.

- Cell-derived membrane vesicles that are released in body fluids are emerging as potential non-invasive biomarkers for diseases like cancer. Techniques capable of measuring the size and concentration of such membrane vesicles directly in body fluids are urgently needed. Here we report on a microfluidic chip with integrated light sheet illumination, and demonstrate accurate fluorescence Single Particle Tracking measurements of the size and concentration of membrane vesicles in cell culture medium and in interstitial fluid collected from primary human breast tumours.

- Cell-derived membrane vesicles that are released in biofluids, like blood or saliva, are emerging as potential non-invasive biomarkers for diseases, such as cancer. Techniques capable of measuring the size and concentration of membrane vesicles directly in biofluids are urgently needed. Fluorescence single particle tracking microscopy has the potential of doing exactly that by labelling the membrane vesicles with a fluorescent label and analysing their Brownian motion in the biofluid. However, an unbound dye in the biofluid can cause high background intensity that strongly biases the fluorescence single particle tracking size and concentration measurements. While such background intensity can be avoided with light sheet illumination, current set-ups require specialty sample holders that are not compatible with high-throughput diagnostics. Here, a microfluidic chip with integrated light sheet illumination is reported, and accurate fluorescence single particle tracking size and concentration measurements of membrane vesicles in cell culture medium and in interstitial fluid collected from primary human breast tumours are demonstrated.
