Prediction of survival and weaning probability in VA ECMO (veno-arterial extracorporeal membrane oxygenation) patients could be of great benefit for real-time decision making on VA ECMO initiation in critical ill patients. We investigated whether the SAPS II score would be a real-time determinant for VA ECMO initiation and could be a predictor of survival and weaning probability in patients on VA ECMO. ⋯ Although the precise predictive scoring systems for VA ECMO still remains one of the most difficult challenges to ECMO physicians, the SAPS II score could provide valuable information on prognosis to patient himself, family members and caretakers, and might help physicians increase the survival rate and might avoid a waste of healthcare resources.

The role of high-flow nasal cannula oxygen therapy (HFNC) in respiratory management of acute exacerbation of interstitial pneumonia (AE-IP) is unknown. ⋯ HFNC might be a feasible option in respiratory management of AE-IP.

Conventional transbronchial biopsies have a low diagnostic yield for interstitial lung disease (ILD) and peripheral lung nodules due to crush artifact and smaller tissue samples. Transbronchial lung cryobiopsies (TBLC) circumvent these drawbacks but are associated with higher incidence of complications including life threatening airway bleeding and pneumothoraces. ⋯ The aim of this review is to investigate the existing literature for RP-EBUS assisted TBLC for diagnosing both ILD and peripheral lung nodules. We will describe the techniques used and compare the diagnostic yield and complication rates with other modalities.

The introduction of immune checkpoint inhibitors have greatly improved clinical outcomes in several cancer types, revolutionizing the management of a wide variety of tumors endowed with poor prognosis. Despite its success, high grade immune related adverse events were observed in patients treated with checkpoint inhibitors. ⋯ In this review we discuss possible mechanisms involved in cardiac toxicity triggered by inhibition of cytotoxic T lymphocyte antigen 4 (CTLA-4) and programmed cell death 1 (PD-1) pathway, the most prominent checkpoint inhibitors available in the clinic. Major cardiovascular events associated with checkpoint inhibitors adds another layer of complexity in cancer therapy and urges for an interdisciplinary approach between oncologists, cardiologists, and immunologist.

Chronic obstructive pulmonary disease (COPD) and obstructive sleep apnoea (OSA) syndrome are both highly prevalent, affecting at least 10% of the general adult population, and each has been independently associated with an increased risk of cardiovascular disease. The presence of both disorders together, commonly referred to as the overlap syndrome, is also highly prevalent, although various clinical and pathophysiological factors associated with COPD may increase or decrease the likelihood of OSA. Lung hyperinflation reduces the likelihood of obstructive apnoea, whereas right heart failure increases the likelihood as a result of rostral fluid shift causing upper airway narrowing in the supine position while asleep. ⋯ Cardiac sympathetic activity is increased in patients with the overlap syndrome when compared to each disorder alone, but echocardiographic evidence of left ventricular strain is no greater in overlap patients when compared to COPD alone. While survival might be expected to be worse in overlap patients, recent evidence surprisingly indicates that the incremental contribution of lung function to mortality diminishes with increasing severity of OSA. Identification of co-morbid OSA in patients with COPD has practical clinical significance as appropriate positive airway pressure therapy in COPD patients with co-existing OSA is associated with improved morbidity and mortality.
