Our aim was to assess the efficacy of thoracic epidural anesthesia (EA) followed by postoperative epidural infusion (EI) and patient-controlled epidural analgesia (PCEA) with ropivacaine/fentanyl in off-pump coronary artery bypass grafting (OPCAB). ⋯ In OPCAB, EA with ropivacaine/fentanyl decreases arterial pressure transiently, optimizes myocardial performance and influences the perioperative fluid and vasoactive therapy. Postoperative EI combined with PCEA improves lung function and reduces time to extubation.

SvO2 to monitor resuscitation of septic patients: let's just understand the basic physiology.
Real-time monitoring of mixed venous oxygen blood saturation (SvO2) or of central venous oxygen blood saturation is often used during resuscitation of septic shock. However, the meaning of these parameters is far from straightforward. In the present commentary, we emphasize that SvO2--a global marker of tissue oxygen balance--can never be simplistically used as a marker of preload responsiveness, which is an intrinsic marker of cardiac performance. ⋯ In other patients, because of a profound impairment of oxygen extraction capacities, SvO2 can be abnormally high even in patients who are still able to respond positively to fluid infusion. In any case, other reliable dynamic parameters can help to address the important question of fluid responsiveness/unresponsiveness. However, whether fluid administration in fluid responders and high SvO2 would be efficacious to reduce tissue dysoxia in the most injured tissues is still uncertain.

Mathematical giftedness is a form of intelligence related to enhanced mathematical reasoning that can be tested using a variety of numerical and spatial tasks. A number of neurobiological mechanisms related to exceptional mathematical reasoning ability have been postulated, including enhanced brain connectivity. ⋯ The math-gifted showed heightened intrahemispheric frontoparietal connectivity, as well as enhanced interhemispheric frontal connectivity between the dorsolateral prefrontal and premotor cortex. These enhanced connectivity patterns are consistent with previous studies linking increased activation of the frontal and parietal regions with high fluid intelligence, and may be a unique neural characteristic of the mathematically gifted brain.

Mindfulness-based 'third wave' cognitive and behavioural therapies versus other psychological therapies for depression.
This is the protocol for a review and there is no abstract. The objectives are as follows: To examine the effectiveness and acceptability of all third wave CBT approaches compared with all other psychological therapy approaches for acute depression. To examine the effectiveness and acceptability of different third wave CBT approaches (ACT,compassionate mind training, functional analytic psychotherapy, extended behavioural activation and meta-cognitive therapy) compared with all other psychological therapy approaches for acute depression. To examine the effectiveness and acceptability of all third wave CBT approaches compared with different psychological therapy approaches (psychodynamic, behavioural, humanistic, integrative, cognitive-behavioural) for acute depression.
