Discourse communities require a network of communication where the members of it can be any amount of distance apart as long as they operate with the same language, but speech communities require proximity to convey the culture of their language.
Pragmatic classification of the causes of high D-dimer. Abstract. Venous thromboembolism (VTE) remains the most. common preventable cause of in-hospital death and D-dimer. (DD) is one of the essential diagnostic tools for it. Each risk. factor for VTE can raise DD and they are numerous: 24 listed in 2008 European Guidelines.
Patients are considered low probability if the score is < 2, moderate if the score is 2 to 6 and high if the score is > 6. D-dimer levels should be assessed in all patients classified as low probability. Pulmonary embolism can be ruled out if score is < 2 and D-dimer levels are < 500 Î¼g/L.
