Currently, there are no studies addressing the influence of age on the prognostic information of N-terminal pro-B-type natriuretic peptide (NT-proBNP) in Asian population with acute coronary syndrome (ACS). The purpose of this study was to investigate the prognostic performance of NT-proBNP in Chinese patients with ACS across different age groups. A total of 1512 ACS patients with venous blood NT-proBNP measured were enrolled. ⋯ NT-proBNP levels are independently associated with mortality in each age group [1st group: HR 2.19 95 % CI (1.17-4.10); 2nd group: HR 1.82 95 % CI (1.04-3.20); 3rd group: HR 1.48 95 % CI (1.09-2.01), P interaction = 0.062]. NT-proBNP improves discrimination and reclassification for mortality beyond thrombolysis in myocardial infarction score in patients of all ages. The optimal NT-proBNP cutoff points for predicting mortality in three age groups are 1511, 2340, and 2883 pg/ml, respectively. In conclusion, NT-proBNP is a valuable biomarker in predicting long-term mortality and provides an improvement in discrimination and reclassification for prognosis in ACS patients of all ages.

Observational Study
Apneic oxygenation is associated with a reduction in the incidence of hypoxemia during the RSI of patients with intracranial hemorrhage in the emergency department.
Critically ill patients undergoing emergent intubation are at risk of oxygen desaturation during the management of their airway. Patients with intracranial hemorrhage (ICH) are particularly susceptible to the detrimental effects of hypoxemia. Apneic oxygenation (AP OX) may be able to reduce the occurrence of oxygen desaturation during the emergent intubation of these patients. ⋯ In the multivariate logistic regression analysis the use of AP OX was associated with a reduced odds of desaturation (aOR 0.13; 95 % CI 0.03-0.53). Patients with ICH who received AP OX during RSI in the ED were seven times less likely to have an oxygen saturation of <90 % during the intubation compared to patients who did not receive AP OX. AP OX is a simple intervention that may minimize the risk of oxygen desaturation during the RSI of patients with ICH.

Currently available anticoagulants have limitations for long-term treatment of venous thromboembolism (VTE). We have evaluated the efficacy and safety of direct oral anticoagulants (DOACs) for extended treatment of VTE. Four randomized controlled trials (RCTs) comparing DOACs (apixaban, rivaroxaban, and dabigatran) with placebo or warfarin for extended treatment of VTE were published. ⋯ Risk of major bleeding is not different with DOACs compared to placebo/warfarin. However, DOACs are associated with a significantly higher rate of the composite of major and clinically relevant bleeding compared to placebo. In conclusion, DOACs are effective and safe for the extended treatment of VTE, and may reduce the risk of all-cause mortality.

Portal vein thrombosis (PVT) dramatically changes the prognosis of cirrhotic patients, especially those waiting for liver transplantation. However, the possible contribution to PVT of von Willebrand factor (VWF) and ADAMTS-13 is poorly documented. The aim of our study was to assess the presence of alterations of VWF and ADAMTS-13 serum levels in cirrhotic patients with PVT. ⋯ No correlation was found between the Child-Pugh score and ADAMTS-13 activity. In multivariable logistic regression analysis performed on data concerning both group PVT and without PVT, only the ADAMTS-13 activity (p = 0.007) was independently and inversely associated with PVT. In conclusion, ADAMTS-13 activity is independently associated with PVT in cirrhotic patients.
