There is evidence that thromboprophylaxis for lower limb immobilised patients reduces the risk of VTE by approximately 50% but there is no international consensus as to which patients should receive thromboprophylaxis. The Plymouth VTE Risk Score was developed to identify patients at particular risk of VTE, in order to offer chemical prophylaxis to reduce their VTE risk. The score showed high completion rates, reliability and consistency. Using the Plymouth VTE Risk Score Version 3 (2014), we found an incidence of clinical VTE of 0.36% with 37.6% of patients being advised to have thromboprophylaxis. This is a lower VTE incidence than in most other studies of this patient group, which is of the order of 2 to 3%. The optimal risk assessment method (RAM) to use in clinical practice is yet to be defined, further clinical research is needed to accurately stratify patient risk and to define optimal risk treatment levels. We suggest research should focus on comparative clinical studies of risk assessment models.A combined fractional tracking controller based on backstepping and active disturbance rejection control (ADRC) is proposed in this work to control uncertain fractional-order systems (FOSs). The proposed method is constructed in two parts first, all internal and external uncertainties are estimated by a fractional-order extended state observer (FO-ESO). Second, fractional backstepping method is used to determine the control law and lead the system to the desired control objectives. The control system stability is verified by fractional Lyapunov-like lemma and two numerical simulations confirm the efficiency of the proposed combined ADRC-based backstepping controller.Management of patients with neuroendocrine neoplasms (NEN
