Thymectomy in myasthenia gravis: proposal for a predictive score of postoperative myasthenic crisis.
Thymectomy plays an important role in patients with myasthenia gravis (MG). This study aimed to explore predictors of postoperative myasthenic crisis (POMC) after thymectomy and to define a predictive score of respiratory failure. ⋯ Our model facilitates the stratification of patient risk and prediction of the occurrence of POMC. Moreover, it could help to guide the anaesthesiologist's decision on the duration of intubation. Further studies based on larger series are needed to confirm these preliminary data.

The use of artificial chordae techniques has increased the number of mitral valve lesions which are amenable to repair. Artificial chordae can be adapted for a wide range of mitral valve pathologies including restricting the motion of overly mobile 'floppy' Barlow disease leaflets, replacing diseased chordae and improving coaptation in degenerative disease. There is continuing concern about the long-term performance of artificial chordae, which become endothelialized over time and may exhibit complications during the early or late follow-up period. ⋯ A number of problems remain in the use of artificial chordae, especially the proper determination of their length. Techniques that solve these issues may enhance patient outcomes further.

Multicenter StudyMorbidity and mortality in a large series of surgical patients with pulmonary metastases of colorectal carcinoma: a prospective multicentre Spanish study (GECMP-CCR-SEPAR).
Little information is available on postoperative morbidity and mortality after pulmonary metastasectomy. We describe the postoperative morbidity and mortality in a large multicentre series of patients after a first surgical procedure for pulmonary metastases of colorectal carcinoma (CRC) and identify the pre- and intraoperative variables influencing the clinical outcome. ⋯ The first episode of lung surgery for pulmonary metastases of CRC was associated with very low mortality and reoperation rates (<1%). The postoperative morbidity rate was 16%. Independent risk factors of postoperative morbidity were major lung resection and respiratory and/or cardiovascular co-morbidity. Video-assisted surgery showed a protective effect.

Association of body mass index and outcomes after major lung resection.
Obesity has been thought to predispose patients to excess morbidity after lung resection because of decreased diaphragm excursion, reduced lung volumes and relative immobility. We assessed the relationship of body mass index (BMI) to acute outcomes after major lung resection. ⋯ Being overweight or obese does not increase the risk of complications after major lung resection. In contrast, patients who are underweight are at significantly increased risk of pulmonary complications and mortality. Knowledge of the relationship of BMI to perioperative risk for major lung resection is essential in proper risk stratification.

High-sensitivity troponin T as a biomarker for the development of atrial fibrillation after cardiac surgery.
Atrial fibrillation (AF) occurs in ∼ 30% of patients undergoing coronary artery bypass grafting (CABG) and in 40% of patients after valve surgery. High-sensitivity cardiac troponin T (hsTnT) is a specific and high-sensitivity marker of myocardial injury, while N-terminal proB-type natriuretic peptide (NT-proBNP) is an established biomarker for wall remodelling. We investigated whether hsTnT and NT-proBNP levels could be used as valuable biomarkers for AF occurrence after cardiac surgery. ⋯ High presurgical hsTnT levels were independently predictive of patients developing AF after cardiac surgery. hsTnT levels determined post-surgery suggest that cardiac perioperative myocardial injury is not associated with postoperative AF development. NT-proBNP did not reach statistical significance as a biomarker for AF prediction.
