Conscious monitoring and control (reinvestment) in surgical performance under pressure. [PDF]

, 2012
Research on intraoperative stressors has focused on external factors without considering individual differences in the ability to cope with stress. One individual difference that is implicated in adverse effects of stress on performance is "reinvestment,"

Put pressure worldwide on blood pressure control [PDF]

Journal of Thoracic Disease, 2016
There is a close relationship between high blood pressure (BP) levels and the risk of cardiovascular disease (CVD) and chronic kidney disease (1). The risk of these clinical outcomes is lowest at a BP of around 115/75 mmHg.
