Malnutrition and Perioperative Nutritional Support in Retroperitoneal Sarcoma Patients: Results from a Prospective Study.

Introduction: Retroperitoneal soft tissue sarcomas (RPSs) are mesenchymal neoplasms. The prevalence of protein energetic malnutrition (PEM) and its impact in RPS patients who were candidates for surgery is unknown.

Materials And Methods: A prospective feasibility study enrolled 35 patients with primary RPS who were candidates for extended multivisceral resection.

Inflammation and primary graft dysfunction after lung transplantation: CT-PET findings.

Background: The leading cause of early mortality after lung transplantation is Primary graft dysfunction (PGD). We assessed the lung inflammation, inflation status and inhomogeneities after lung transplantation. Our purpose was to investigate the possible differences between patients who did or did not develop PGD.

Sodium bicarbonate treatment during transient or sustained lactic acidemia in normoxic and normotensive rats.

Introduction: Lactic acidosis is a frequent cause of poor outcome in the intensive care settings. We set up an experimental model of lactic acid infusion in normoxic and normotensive rats to investigate the systemic effects of lactic acidemia per se without the confounding factor of an underlying organic cause of acidosis.

Methodology: Sprague Dawley rats underwent a primed endovenous infusion of L(+) lactic acid during general anesthesia.

β-adrenergic agonist infusion during extracorporeal lung perfusion: effects on glucose concentration in the perfusion fluid and on lung function.

Background: We recently showed in a pig model of ex vivo lung perfusion (EVLP) that lung edema correlates with glucose consumption. We investigated whether salbutamol, a β-adrenergic receptor agonist known to upregulate fluid transport in the lung, modulates glucose concentration in the perfusate during EVLP.

Methods: Lungs from domestic pigs underwent normothermic EVLP.

Management of mechanical ventilation during laparoscopic surgery.

Laparoscopy is widely used in the surgical treatment of a number of diseases. Its advantages are generally believed to lie on its minimal invasiveness, better cosmetic outcome and shorter length of hospital stay based on surgical expertise and state-of-the-art equipment. Thousands of laparoscopic surgical procedures performed safely prove that mechanical ventilation during anaesthesia for laparoscopy is well tolerated by a vast majority of patients.
