Recent epidemiological studies suggest that chronic pain is a clinically under-recognised cause for cardiovascular morbidity and mortality. Up to 30% of patients undergoing surgery report chronic pain, but the impact of pre-existing pain on postoperative cardiovascular outcomes is not known. Chronic pain and cardiovascular dysfunction share fundamental pathological mechanisms. Chronic pain is a modifiable risk factor for perioperative cardiovascular morbidity.

The ability of current depth-of-anaesthesia monitors to differentiate subtle changes in the conscious state has not been well characterised. We examine the variability in bispectral index (BIS) scores associated with disconnected conscious and unconscious states as confirmed by a novel serial awakening paradigm. ⋯ These results agree with previous studies that BIS scores fail to reliably differentiate between states of consciousness, exacerbated by segregating connected, disconnected, and unconscious states. To develop a method that reliably identifies the conscious state of an individual (not an average), work is needed to establish the causal mechanisms of disconnection and unconsciousness.

Citation scores (CS) are traditionally used to measure the impact of scientific publications. Altmetric Attention Scores (AAS), in contrast, consider the digital dissemination of articles across social media platforms to track their audience reach. In this cross-sectional study, we aimed to determine the correlation between AAS and CS in 12 high-impact-factor journals in the category of 'Clinical Medicine'. ⋯ Altmetric Attention Scores correlated with citation scores, suggesting that audience engagement via social media can influence the future impact of publications and their citation scores.
