Disclosure of potential conflicts of interest is used by biomedical journals to guarantee credibility and transparency of the scientific process. Conflict of interest disclosure, however, is not systematically nor consistently dealt with by journals. ⋯ This paper provides a comprehensive editorial perspective on classical conflict of interest-related issues. New insights into current conflicts of interest policies and practices among European Society of Cardiology national cardiovascular journals, as derived from a cross-sectional survey using a standardized questionnaire, are discussed.

Our aim was to evaluate the effect of the baroreflex mechanism upon peripheral blood volume during sympathetic stimulation by orthostatism. ⋯ The sequence method showed a strong baroreflex effect upon peripheral blood volume that became more apparent during sympathetic stimulation with orthostatism. This approach could be clinically useful for the evaluation of blood volume regulation for many diseases such as diabetes mellitus and heart failure, and during therapeutic interventions such as hemodialysis.
