The clinical benefits of a concomitant mitral valve (MV) surgery in patients with moderate ischemic mitral regurgitation (iMR) undergoing coronary artery bypass grafting (CABG) remain controversial. ⋯ The addition of a concomitant MV surgery increased the risk of early mortality and complications in patients with moderate iMR undergoing CABG. In long-term clinical and echocardiographic outcomes, a concomitant MV surgery seemed to confer no significant clinical benefits.

Immunotherapy has become standard of care in advanced non-small cell lung cancer (NSCLC) in a number of settings. Radiotherapy remains an important and potentially curative treatment for localized and locally advanced NSCLC not amenable to surgery. While the principal cytotoxic effect of ionizing radiation is via DNA damage, the effect on tumour microenvironment, promoting dendritic cell presentation of tumour-derived antigens to T cells stimulating the host adaptive immune system to mount an immune response against tumours cells, has become of particular interest when combining immunomodulating agents with radiation. ⋯ Increasing understanding of the interaction between tumour, radiation and immune cells at a molecular level provides a further opportunity for intervention to enhance the potential synergy between radiation and immunotherapy. Applying the potential efficacy of combination therapy to clinical practice requires caution particularly to ensure the safety of the two treatment modalities in early phase clinical trials, many of which are currently underway. We review the biological basis for combining radiation and immunotherapy and examine the existing pre-clinical and clinical evidence and the challenges posed by the new combination of treatments.

The optimal management of ischemic mitral regurgitation (IMR) is controversial. The aim of this study was to examine our eight years' experience of surgical treatment in patients with IMR, and to compare outcomes of mitral valve repair versus replacement with concomitant coronary artery bypass grafting (CABG). ⋯ Our preliminary findings showed that the surgical outcome of mitral valve repair might be comparable to that of MVR in terms of early mortality and long-term survival. However, mitral valve repair was associated with a higher residual or recurrent mitral regurgitation rate. According to the latest literature, the role of MVR can justifiably be indicated for severe IMR. As for moderate IMR, CABG alone without mitral valve intervention may provide similar clinical outcomes.

Mechanical ventilation, especially large tidal volume (Vt) one-lung ventilation (OLV), can cause ventilator-induced lung injury (VILI) that can stimulate cytokines. Meanwhile, cytokines are considered very important factor influencing coronary heart disease (CHD) patient prognosis. So minimization of pulmonary inflammatory responses by reduction of cytokine levels for CHD undergoing lung resection during OLV should be a priority. Because previous studies have demonstrated that lung-protective ventilation (LPV) reduced lung inflammation, this ventilation approach was studied for CHD patients undergoing lung resection here to evaluate the effects of LPV on pulmonary inflammatory responses. ⋯ LPV can effectively reduce the airway pressure, improve Cdyn and PaO2, reduce concentrations of IL-6 and CRP during lung resection of CHD patients.Trial registration: The trial was registered in the Chinese Clinical Trial Registry.

Airway management in tracheal resections presents many challenges. The aim of this retrospective analysis is to report the efficacy and complications associated with the use of the laryngeal mask airway in this procedure. ⋯ Based on this analysis of 54 patients, we would consider the laryngeal mask airway a feasible alternative to the tracheal tube for airway management and ventilation during open tracheal surgery.
