Is a V/Q scan based algorithm correctly used to diagnose acute pulmonary embolism? A daily practice survey.

Introduction: Diagnostic flow-charts for pulmonary embolism (PE) are widely implemented in the management of PE. A major drawback of a diagnostic PE algorithm is the use of several consecutive tests, which may be challenging in daily clinical practice.

Materials And Methods: Evaluation whether the use of an algorithm, starting with a ventilation/perfusion (V/Q) scan after a normal chest X-ray, is correctly used in daily clinical practice for diagnosing acute PE.

Versican expression is associated with tumor-infiltrating CD8-positive T cells and infiltration depth in cervical cancer.

Cervical carcinoma is the second most frequent cancer type in women worldwide. Both inflammatory cells and stromal cells are important for tumor progression. Stromal cells produce growth factors and extracellular matrix and provide an adequate environment for angiogenesis.
