This book is the first comprehensive overview of the emerging field of cuffless blood pressure monitoring. Increasing clinical evidence proves that longitudinal measurements of blood pressure allow for earlier detection and better management of multiple medical conditions and for superior prediction of cardiovascular events. Unfortunately, today's clinical and industry standards for blood pressure monitoring still require the inflation of a pneumatic cuff around a limb each time a measurement is taken. Over the last decades clinicians, scientists and device manufacturers have explored the feasibility of technologies that reduce or even completely eliminate the need of cuffs, initiating the era of cuffless blood pressure monitoring. Among the existing literature, this book is intended to be a practical guide to navigate across this emerging field. The chapters of the handbook have been elaborated by experts and key opinion leaders in the domain, and will guide the reader along the clinical, scientific, technical, and regulatory aspects of cuffless blood pressure monitoring.
This book provides a reference for people working in the design, development, and manufacturing of medical devices. While there are no statistical methods specifically intended for medical devices, there are methods that are commonly applied to various problems in the design, manufacturing, and quality control of medical devices. The aim of this book is not to turn everyone working in the medical device industries into mathematical statisticians; rather, the goal is to provide some help in thinking statistically, and knowing where to go to answer some fundamental questions, such as justifying a method used to qualify/validate equipment, or what information is necessary to support the choice of sample sizes. While, there are no statistical methods specifically designed for analysis of medical device data, there are some methods that seem to appear regularly in relation to medical devices. For example, the assessment of receiver operating characteristic curves is fundamental to development of diagnostic tests, and accelerated life testing is often critical for assessing the shelf life of medical device products. Another example is sensitivity/specificity computations are necessary for in-vitro diagnostics, and Taguchi methods can be very useful for designing devices. Even notions of equivalence and noninferiority have different interpretations in the medical device field compared to pharmacokinetics. It contains topics such as dynamic modeling, machine learning methods, equivalence testing, and experimental design, for example. This book is for those with no statistical experience, as well as those with statistical knowledgeable—with the hope to provide some insight into what methods are likely to help provide rationale for choices relating to data gathering and analysis activities for medical devices.

The last documented sighting of the Ivory-billed Woodpecker--one of
the rarest and most intriguing animals in the world--was noted over
50 years ago. Long thought to be extinct, the 2005 announcement of
a sighting in Arkansas sparked tremendous enthusiasm and hope that
this species could yet be saved. But the subsequent failure of a
massive search to relocate Ivorybills in Arkansas made hope for the
species' revival short-lived.

This book provides a powerful diagnosis of why the global governance of science struggles in the face of emerging powers. Through unpacking critical events in China and India over the past twenty years, it demonstrates that the 'subversiveness' assumed in the two countries' rise in the life sciences reflects many of the regulatory challenges that are shared worldwide. It points to a decolonial imperative for science governance to be responsive and effective in a cosmopolitan world. By highlighting epistemic injustice within contemporary science, the book extends theories of decolonisation. -- .
An Innovative Approach to Studying and Treating Cancer: Targeting pH describes one of the few characteristics of cancer that is not shared by normal tissues: the reversal or inversion of the pH gradient when intracellular pH becomes alkaline and extracellular pH becomes acid.
