“…Similar eCB results were recently reported in another study conducted by Galdino et al (2014) employing resistance exercise instead of aerobic exercise. 15 Thus, the results from these studies provide support for the endocannabinoid hypothesis of EIH.…”

The purpose of this study was to examine opioid and endocannabinoid mechanisms of exercise-induced hypoalgesia (EIH). Fifty-eight men and women (mean age = 21 yrs) completed three sessions. During the first session, participants were familiarized with the temporal summation of heat pain and pressure pain protocols. In the exercise sessions, following double-blind administration of either an opioid antagonist (50 mg naltrexone) or placebo, participants rated the intensity of heat pulses and indicated their pressure pain thresholds (PPT) and ratings (PPR) before and after 3 minutes of submaximal isometric exercise. Blood was drawn before and after exercise. Results indicated circulating concentrations of two endocannabinoids, N-arachidonylethanolamine (AEA) and 2-arachidonoylglycerol (2-AG) as well as related lipids oleoylethanolamide (OEA), palmitoylethanolamide (PEA), N-docsahexaenoylethanolamine (DHEA), and 2-oleoylglycerol (2-OG) increased significantly (p < 0.05) following exercise. PPT increased significantly (p < 0.05) while PPR decreased significantly (p < 0.05) following exercise. Also, temporal summation ratings were significantly lower (p < 0.05) following exercise. These changes in pain responses did not differ between placebo or naltrexone conditions (p > 0.05). A significant association was found between EIH and DHEA. These results suggest involvement of a non-opioid mechanism in EIH following isometric exercise.

“…The weight of the model was 650 g, this was designed to mimic the weight of the BiVACOR device. After placing the device within the chest cavity, we recognized that it may be beneficial to anchor or suspend the device in a similar fashion to the SynCardia TAH 10 . However, the necessity of this is currently uncertain and future studies will explore the need for suspension.…”

Background BiVACOR is a novel total artificial heart (TAH) utilizing a single centrifugal magnetically levitated rotor with the ability to modulate pulsatile flow. The device has been successfully tested in a bovine model. We undertook a multicenter anatomical and virtual fitting study of the BiVACOR in patients undergoing heart transplantation. Methods 10 patients were recruited across two heart transplant centers. A sterilized 1:1 titanium model of the device was inserted into the patient’s chest post heart explant, prior to implantation of the donor heart. Measurements were recorded in situ. The device was then removed. Following this, retrospective 3D reconstructions were created from computed tomography chest scans to simulate a virtual fitting. Results Mean age was 53 years (range 38–67). Mean BMI was 28 (range 20–37). Heart failure etiology was varied—with ischemic cardiomyopathy being the most common. Mean spine‐to‐sternum distance at the tenth thoracic vertebrae (T10) was 14 cm (range 11–18). Mean aorta to aortic Port distance was 0.2 cm (range 0–0.5). Mean pulmonary artery to pulmonary artery port distance was 4.2 cm (range 1–7). The device fitted suitably in all patients without gross distortion to the geometry between native vessel/chamber and port. Conclusions This study described the anatomical and virtual fitting of the BiVACOR TAH. The device fit well within the chest cavities of all 10 patients, who represented a variety of body morphologies and heart failure etiology.

The use of transesophageal echocardiography (TEE) in the operating room and intensive care unit can provide invaluable information on cardiac as well as abdominal organ structures and function. This approach may be particularly useful when the transabdominal ultrasound examination is not possible during intraoperative procedures or for anatomical reasons. This review explores the role of transgastric abdominal ultrasonography (TGAUS) in perioperative medicine. We describe several reported applications using 10 views that can be used in the diagnosis of relevant abdominal conditions associated with organ dysfunction and hemodynamic instability in the operating room and the intensive care unit.
