introductory biostatistics book of the fourth type as defined above. Given the author's ability to describe statistical concepts, I am just a bit disappointed that he did not include some of the more clinical dimensions as well. Nevertheless, those who want a thorough but eminently readable introduction to biostatistics are strongly advised to obtain this book. Communication is a fundamental re...

Microdevices enable clinical diagnostics to be miniaturized for use at the point-of-care (POC). Microdevices can be composed of microfilters, microchannels, microarrays, micropumps, microvalves, and microelectronics, and these mechanical and electrical components can be integrated onto chips to analyze and control biological objects at the microscale. The miniaturization of diagnostic tests off...

The impaired walking nursing diagnosis has been included in NANDA International classification taxonomy in 1998, and this review aims to identify the defining characteristics and related factors in elderly patients in recent literature. Integrative literature review based on the following guiding question: Are there more defining characteristics and factors related to the nursing diagnosis impa...

Conceptual change is a gradual process that occurs as students integrate new information into their existing conceptions. Throughout this process, assessing learning requires measures to diagnose misconceptions and understand how knowledge is changing. We developed three measures of misconceptions to assess students' knowledge early in instruction on decimals that measured the: 1) prevalence of...

Age-related macular degeneration (AMD) is one of the most well-characterized late-onset, complex trait diseases. Remarkable advances in our understanding of the genetic and biological foundations of this disease were derived from a recent convergence of scientific and clinical data. Importantly, the more recent identification of AMD-associated variations in a number of complement pathway genes ...
