Gastrointestinal bleeding (GIB) affects up to 40% of continuous-flow left ventricular assist device (CF-LVAD) recipients. A higher risk of GIB is seen in CF-LVAD recipients with lower device pulsatility without a known mechanism. One hypothesis is that the novel hemodynamics in CF-LVAD recipients affect angiogenesis signaling. We aimed to (1) measure serum levels of angiopoietin (Ang)-1, Ang-2, and VEGF-A in CF-LVAD recipients with and without GIB and in healthy controls and (2) evaluate correlations of those levels with hemodynamics. ⋯ CF-LVAD recipients demonstrated a shift toward a pro-angiogenic phenotype in the angiopoietin axis that is significantly associated with GIB and may be linked to low pulse pressure.

Anti-coagulation is the cornerstone management of acute pulmonary embolism (PE), which is a double-edged sword, as it increases the risk of bleeding. Thus, predicting bleeding risk is necessary. The liver produces most coagulation factors to maintain the coagulation balance. However, the association between liver dysfunction markers and bleeding risk has not been thoroughly investigated. ⋯ In PE patients, AST is an independent factor in predicting the 1-month bleeding risk, and a novel joint model that combines AST and PE-SARD score improved the predictive efficiency for the 1-month bleeding risk.

The capacity of ChatGPT in academic environments and medical exams is being discovered more and more every day. In this study, we tested the success of ChatGPT on Turkish-language thoracic surgery exam questions. ⋯ When the results of this study and other similar studies in the literature are evaluated together, ChatGPT, which was developed for general purpose, can also produce successful results in a specific field of medicine. AI-powered applications are becoming more and more useful and valuable in providing academic knowledge.
