Although team-based care has been shown in many sectors to improve outcomes, very little work has been done with the thoracic surgical patient. This review article focuses on this and, extrapolating from other closely related surgical fields, teamwork in thoracic surgery will be reviewed for outcome efficacy and substance. ⋯ To improve outcome, the thoracic surgical team, centered on the anesthesiologist and surgeon, will display the 'Big 5' attributes of highly effective teams. There are attributes of poor teams, which the dyad should avoid in order to increase the team's function and thus outcome.

Right ventricle: current knowledge of echocardiographic evaluation of this "forgotten" chamber.
In the past the right ventricle (RV) has been traditionally regarded as a simple conduit between the venous system and the pulmonary circulation and it has aroused little interest in both clinical and echocardiographic cardiologists to such an extent that it has been defined as the "forgotten chamber." Subsequently it was clearly shown that the right heart (RH) plays an important physiologic role in cardiac activity, and that congenital or acquired alterations in its structure and function have an important prognostic value. Aim of this review is to shed the light on the echocardiographic approach to this cardiac chamber. ⋯ However, RV may now be evaluated quantitatively and qualitatively in many ways, and some new methods can partially overcome some of the limits imposed by its complex anatomy, thereby yielding a quantitative evaluation. Furthermore, due to the wide range of pathologies which may involve the RV a disease-oriented approach should be considered in the echocardiographic investigation of right heart disease.

ReviewNutrition support for patients on mechanical circulatory support.
No specific guidelines on medical nutrition therapy (MNT) in patients on different types of mechanical circulatory support (MCS) devices yet exist and overall evidence is limited. The purpose of this narrative review is to provide an overview about current existing evidence, which might be of underrecognized importance for the patients' short-term and long-term clinical and functional outcomes. ⋯ The importance of MNT for patients on MCS still often remains underrecognized, which might be of particular relevance in view of the significant metabolic alterations, the long treatment period, and severity of illness in these patients. Further research on more targeted MNT approaches in those patients is urgently needed for the generation of evidence-based guidelines for this specific cohort of critically ill patients.

Prediction of pain using electrocardiographic-derived autonomic measures: A systematic review.
Pain is a major clinical challenge, and understanding the pathophysiology is critical for optimal management. The autonomic nervous system reacts to pain stimuli, and autonomic dysfunction may predict pain sensation. The most used assessment of autonomic function is based on electrocardiographic measures, and the ability of such measures to predict pain was investigated. ⋯ Pain is a debilitating problem, and the ability to predict occurrence and severity would be a useful clinical tool. Basal autonomic tone has been suggested to influence pain perception. This systematic review investigated electrocardiographic-derived autonomic tone and found that increased parasympathetic tone could predict pain reduction in different types of pain.

ReviewSetting positive end-expiratory pressure: role in diaphragm-protective ventilation.
With mechanical ventilation, positive end-expiratory pressure (PEEP) is applied to improve oxygenation and lung homogeneity. However, PEEP setting has been hypothesized to contribute to critical illness associated diaphragm dysfunction via several mechanisms. Here, we discuss the impact of PEEP on diaphragm function, activity and geometry. ⋯ Setting PEEP could play an important role in both lung and diaphragm protective ventilation. Both high and low PEEP levels could potentially introduce or exacerbate diaphragm myotrauma. Today, the impact of PEEP setting on diaphragm structure and function is in its infancy, and clinical implications are largely unknown.
