Comparative StudyPrognosis of non-small-cell lung cancer patients with positive pleural lavage cytology.
Positive pleural lavage cytology (PLC) is considered as a precursor condition of pleural dissemination (PD) or malignant pleural effusion (PE), and one of the poor prognostic factors in surgically resected non-small-cell lung cancer (NSCLC) patients. Although PD and PE are classified as M1a, PLC does not contribute to the tumour, node and metastasis (TNM) classification of the Union Internationale Contre le Cancer. This study aimed to evaluate the prognostic effect of positive PLC status in surgically resected NSCLC patients compared with PD and/or PE. We also aimed to consider the contribution of positive PLC status to the TNM classification. ⋯ Positive pre-PLC had the significant prognostic effect in surgically resected NSCLC patients. However, it is not a contraindication for surgical resection, unlike PD and/or PE. Our data suggest that positive pre-PLC should be classified as pT3 in next TNM classification.

Comparative Study Observational StudyFull sternotomy versus right anterior minithoracotomy for isolated aortic valve replacement in octogenarians: a propensity-matched study †.
Surgical aortic valve replacement (AVR) is increasingly performed in elderly patients with good perioperative outcomes and long-term survival, resulting in significant health-related quality-of-life benefits. This study aimed to evaluate the outcome of patients aged ≥ 80 years undergoing isolated AVR through a right anterior minithoracotomy (RAMT) and compare it with a full sternotomy (FS). ⋯ Minimally invasive AVR through right anterior minithoracotomy can be safely performed in patients aged ≥80 years with acceptable morbidity and mortality rates. It is an expeditious and effective alternative to full sternotomy AVR and might be associated with lower postoperative stroke incidence, earlier extubation and shorter hospital stay.

Comparative Study Observational StudyUniportal video-assisted thoracoscopic lobectomy: an alternative to conventional thoracoscopic lobectomy in lung cancer surgery?
Although the standard video-assisted thoracoscopic surgery (VATS) approach is generally performed through two to four incisions, uniportal VATS pulmonary resection has recently been reported to be a promising, less invasive alternative. To evaluate the adequacy of uniportal VATS lobectomy as an alternative to conventional VATS lobectomy in lung cancer, we analysed and compared the outcomes of uniportal and conventional VATS lobectomies. ⋯ The similar perioperative results of uniportal VATS lobectomy compared with conventional VATS lobectomy suggest that uniportal VATS is a viable alternative approach to the conventional VATS approach in selected patients, especially in patients with early peripheral lung cancer with good anatomy and in good general condition.

A new tissue-engineered biodegradable surgical patch for high-pressure systems †.
Ideal alternatives for replacing native arteries, which have biocompatibility such as growth potential, anti-thrombogenesis and durability, have yet to be discovered. We previously demonstrated the utility of tissue-engineered vascular autografts; however, the use of these autografts is limited to low-pressure conditions. The aim of this study was to create the tissue-engineered arterial patch (TEAP) that could be used in high-pressure systems, and to evaluate the maturation in this regenerative tissue. ⋯ We demonstrated the maturation of endothelial and smooth muscle cells in TEAP, suggesting that this biodegradable polymer scaffold could be used as an alternative vascular material even in high-pressure systems.

Veno-veno-arterial extracorporeal membrane oxygenation for respiratory failure with severe haemodynamic impairment: technique and early outcomes.
Patients with respiratory failure may benefit from veno-venous and veno-arterial extracorporeal membrane oxygenation (ECMO) support. We report on our initial experience of veno-veno-arterial (v-v-a) ECMO in patients with respiratory failure. ⋯ Veno-veno-arterial ECMO is a technically feasible rescue strategy in treating patients presenting with combined respiratory and haemodynamic failure.
