This paper studies the advances that have participated in the development of preservation solutions for the combined kidney-pancreas transplantation. These developments have been associated most importantly with hypothermia, the use of colloid solutions with high oncotic pressure, and the maintenance of near-intracellular ionic concentration. At the present time, the more effective solutions are the plasma-like modified Silica Gel Fraction and the starch and lactobionate based solution such as, the UW. Further advances in this area, would allow for improved results in the combined kidney-pancreas transplant preparation.

The introduction of minimally invasive coronary artery bypass surgery has expanded the technical armementarium for operative treatment of coronary artery disease. Minimal access surgery using partial sternotomy or anterior intercostal minimal thoracotomy can be combined with videoscopic techniques or port-access-methods. Either atrio-aortal cannulation, femoro-femoral or jugular-femoral connections to the pump are possible for extracorporal circulation (ECC). Even endoluminar occlusion of the aorta and application of cardioplegia into the aortic root can be considered and applied. Extracorporal circulation has developed into a safe standardized method. As far as pathophysiology is concerned, the decision to use ECC or not is of much more importance than the grade of invasiveness. Fundamentally we therefore need to distinguish between minimally invasive methods with and without ECC. Video-assisted coronary surgery in hearts under hypothermia and fibrillation with ECC is also recommended occasionally. Minimally invasive coronary artery procedures on beating hearts without ECC have to be done in a stabilized and bloodless operative field to allow the construction of high standard anastomoses between bypass grafts and coronary arteries. In practice, silicon occluders, epicardial and myocardial suture occlusion and fixation, mechanical stabilization devices, and pharmacologic induction of bradycardia are used. In principle a skilled surgeon should be familiar with all these methods to select the most suitable solution for the special clinical problem. A final judgement about each method is not possible up to now. High patients numbers have to be recruited in the groups and subgroups due to low mortality (1%) and morbidity (5%), otherwise statistical significance of the results cannot be gained.

Neurotensin (NT) exerts naloxone-insensitive antinociceptive action through its binding to both NTS1 and NTS2 receptors and NT analogs provide stronger pain relief than morphine on a molecular basis. Here, we examined the analgesic/adverse effect profile of a new NT(8-13) derivative denoted JMV2009, in which the Pro10 residue was substituted by a silicon-containing unnatural amino acid silaproline. We first report the synthesis and in vitro characterization (receptor-binding affinity, functional activity and stability) of JMV2009. We next examined its analgesic activity in a battery of acute, tonic and chronic pain models. We finally evaluated its ability to induce adverse effects associated with chronic opioid use, such as constipation and analgesic tolerance or related to NTS1 activation, like hypothermia. In in vitro assays, JMV2009 exhibited high binding affinity for both NTS1 and NTS2, improved proteolytic resistance as well as agonistic activities similar to NT, inducing sustained activation of p42/p44 MAPK and receptor internalization. Intrathecal injection of JMV2009 produced dose-dependent antinociceptive responses in the tail-flick test and almost completely abolished the nociceptive-related behaviors induced by chemical somatic and visceral noxious stimuli. Likewise, increasing doses of JMV2009 significantly reduced tactile allodynia and weight bearing deficits in nerve-injured rats. Importantly, repeated agonist treatment did not result in the development of analgesic tolerance. Furthermore, JMV2009 did not cause constipation and was ineffective in inducing hypothermia. These findings suggest that NT drugs can act as an effective opioid-free medication for the management of pain or can serve as adjuvant analgesics to reduce the opioid adverse effects.
