Clinical manifestations and misdiagnosis factors of pulmonary embolism patients seeking treatment in cardiology.

To explore the clinical manifestations and factors leading to misdiagnosis in pulmonary embolism (PE) patients in a cardiology department. We retrospectively analyzed 74 patients diagnosed with PE at our hospital from March 2018 to March 2022, comparing them to 136 patients suspected of PE but excluded by computed tomography pulmonary angiography during the same period. Both groups received the same basic care, including disease counseling, nutritional planning, and monitoring.

Selective Separation of HNO and HCl by Extraction: The Investigation on the Noncovalent Interaction between Extractants and Acids by Density Functional Theory.

There is a huge demand for the highly selective separation of HNO and HCl in many industries, and solvent extraction is considered a feasible method. In this article, DFT calculations were performed to investigate the interactions between acids and extractants including alcohols, ketones, phosphorus, and amines. One of the significant findings to emerge from this study is that amines bind to acids through ion association.
