We find that climate change generally acts to reduce the intensity of influenza epidemics as specific humidity increases. Here, we use a parsimonious influenza model, grounded in theoretical understanding of the link between climate, demography and transmission to project future changes globally. Future climatic and demographic changes may alter both the magnitude, frequency and timing of influenza epidemics and the prospects for pathogen evolution, however, these issues have not been addressed systematically. In the clinical treatment of hypertension, however, this phenomenon has long been ignored, and brachial cuff sphygmomanometric blood pressure (BP) has been used as a reliable alternative to central BP (CBP) until recently.Ĭomments are closed.Seasonal influenza causes a substantial public health burden, as well as being a key substrate for pandemic emergence. INTRODUCTION It has been considered basic knowledge, usually described in textbooks of circulatory physiology, that peripheral systolic blood pressure (SBP) is higher than central aortic SBP due to pulse pressure (PP) amplification. However, if central and peripheral pressure calibrations are equivalent, two major methods to estimate CBP-those based on generalized pressure transfer function or radial late systolic pressure-may be comparable in their accuracy of CBP parameter estimation. Calibration of a peripheral pressure waveform has unresolved problems for any estimation method, due to imperfect brachial sphygmomanometry.
An automated tonometry device utilizing a sensor array is preferable in terms of reproducibility and objectivity. Precise peripheral pressure pulse recording has been enabled by the introduction of arterial applanation tonometry, for which the radial artery may be the optimal site.

To assess estimated CBP appropriately, the accuracy and features of the estimation method should be considered. Because CBP cannot be directly measured noninvasively, it has to be estimated from peripheral pressure pulses. Central aortic blood pressure (CBP) is increasingly considered a better cardiovascular prognostic marker than conventional cuff brachial blood pressure.
