Abstract: The aim of this study was to highlight the epidemiology of brain tumors (BTs) in Sudan during 2014-2017 as retrospective and surveyed questionnaire collected data method. The data (annual incidence, frequencies of BTs based on gender and age, anatomical location, pathologies and geographical distribution) analyzed using EXCEL software which revealed that: BTs increase annually by a factor of 7.2% and predominant among male with 57.1%. The involved anatomical brain sites were midbrain 35%, left brain (30%) and right brain (24%). BTs observed among age groups of 1-10 years old for both gender with increasing similar trend incidence following aging which peaking at 55-65 years old. The common pathologies of brain were atrophy and infarction that represents 13.8% and 7.2% respectively and benign and malignant tumors represented (19.8%) and (34.4%) respectively. The most endemic sectors by BTs were central and Northern of Sudan that represented 45% and 35% respectively, then eastern and southern of Sudan that represented 12% and 8% respectively.

Abstract: A noninvasive estimation of central blood-pressure is required by the researchers or the medical practitioners in the cardiovascular treatment. In this study, first of all, a cardiovascular simulator based on the electrical circuits is described based on the model based approach and then, the representation of aorta model as a pressure transfer function is shown. This representation accelerates the simulator and then, makes it possible to estimate the central blood-pressure from a wearable gouge measurement in a real-time way. The system consisting of a main station, gateways and wearable blood-pressure gauges using one-board microcomputer is actually implemented. The functions and performances of the system are experimentally evaluated and the obtained results show the feasibility of central blood-pressure estimation and the localization of some examinees having wearable gauges with the practical accuracy and speed.
