Antegrade and retrograde arterial perfusion strategy in minimally invasive mitral-valve surgery: a propensity score analysis on 1280 patients.
Recent studies have suggested an increased risk of stroke in patients undergoing minimally invasive mitral-valve surgery with retrograde perfusion when compared with antegrade perfusion. The aim of the present study was therefore to evaluate the impact on early outcome of retrograde arterial perfusion (RAP) strategy vs antegrade arterial perfusion strategy in a consecutive large cohort of patients who underwent minimally invasive mitral-valve surgery through a right minithoracotomy. ⋯ Minimally invasive mitral valve procedure can be performed with low morbidity and mortality. The use of retrograde perfusion is associated with a higher incidence of neurological complications and aortic dissection when compared with antegrade perfusion. Central aortic cannulation allows the avoidance of complications associated with retrograde perfusion while extending the suitability of minimally invasive mitral procedures also to those patients who have an absolute contraindication to femoral artery cannulation.

Comparative StudyEffect of radiofrequency ablation and comparison with surgical sympathectomy in palmar hyperhidrosis.
Hyperhidrosis is a the disorder of excessive sweating in certain regions of the body. It is usually treated with surgical sympathectomy. Radiofrequency therapy has been successfully used for sympatholysis. We tested the primary hypothesis that radiofrequency therapy is independently associated with decreased palmar hyperhidrosis and compared results for patients receiving this treatment with patients who underwent surgical sympathectomy. ⋯ This is the first clinical study to evaluate the role of radiofrequency ablation and compare it with the surgical treatment option for palmar hyperhidrosis. Radiofrequency ablation significantly decreased hyperhidrosis, but it had a lower success rate than surgical sympathectomy.

Randomized Controlled TrialMeasurement of extravascular lung water following human brain death: implications for lung donor assessment and transplantation.
The measurement of extravascular lung water could aid the assessment and guide the management of potential lung donors following brain death. We therefore sought to validate a single indicator thermodilution extravascular lung water index (EVLWI-T) measurement using gravimetry and to assess the impact and clinical correlates of elevated EVLWI-T in potential lung donors and transplant recipients. ⋯ Elevated lung water is found in >50% of potential lung donors, predicts lung suitability for transplant and may adversely affect recipient outcome. Although EVLWI-T intrinsically overestimates gravimetric lung water, its measurement may aid the assessment of organ suitability. Lung water accumulation and the proinflammatory response may both be targets for modifying therapy.

Dynamic trends in cardiac surgery: why the logistic EuroSCORE is no longer suitable for contemporary cardiac surgery and implications for future risk models.
Progressive loss of calibration of the original EuroSCORE models has necessitated the introduction of the EuroSCORE II model. Poor model calibration has important implications for clinical decision-making and risk adjustment of governance analyses. The objective of this study was to explore the reasons for the calibration drift of the logistic EuroSCORE. ⋯ Patient risk factors and case-mix in adult cardiac surgery change dynamically over time. Models like the EuroSCORE that are developed using a 'snapshot' of data in time do not account for this and can subsequently lose calibration. It is therefore important to regularly revalidate clinical prediction models.

Subjective impairment after cardiac surgeries: the relevance of postoperative cognitive decline in daily living.
Postoperative cognitive decline (POCD) is a frequent complication after cardiac surgeries. It remains unclear how relevant this decline in psychometric results is for daily life. The aim of the study was to assess cognitive failures, as seen by patients and close relatives, on a quantitative level. ⋯ The result demonstrates that cognitive side-effects could have a perceivable impact on daily living functions. However, slight deficits are more realized by others than by the patients themselves. Correlations between ratings by others and psychometric cognitive measures indicate that assessment by others is more reliable than self-assessment.
