  • Clinical Implications of Drug Distribution Digoxin accesses its cardiac site of action slowly, over a distribution phase of several hours. Thus, after an intravenous dose, plasma levels fall, but those at the site of action increase over hours. Only when distribution is near-complete does the concentration of digoxin in plasma reflect pharmacologic effect. For this reason, there should be a 6–8 h wait after administration before plasma levels of digoxin are measured as a guide to therapy.

  • Principles of Genetic Variation and Human Traits (See also Chaps. 62 and 64) Variants in the human genome resulting in variation in level of expression or function of molecules important for pharmacokinetics and pharmacodynamics are increasingly recognized. These may be mutations (very rare variants, often associated with disease) or polymorphisms, variants that are much more common in a population. Variants may occur at a single nucleotide [known as single nucleotide polymorphism (SNP)] or involve insertion or deletion of one or more nucleotides.

  • Renal Disease Renal excretion of parent drug and metabolites is generally accomplished by glomerular filtration and by specific drug transporters, only now being identified. If a drug or its metabolites are primarily excreted through the kidneys and increased drug levels are associated with adverse effects, drug dosages must be reduced in patients with renal dysfunction to avoid toxicity. The antiarrhythmics dofetilide and sotalol undergo predominant renal excretion and carry a risk of QT prolongation and arrhythmias if doses are not reduced in renal disease.

  • This book contains twenty client profiles to use in practicing interviewing and diagnostic skills. Ten profiles are of adult cases ranging in age from eighteen to seventy (chapters 3-12). Ten profiles are of child or teen cases ranging in age from seven to seventeen (chapters 13-22). In addition to age, the twenty profiles vary in terms of ethnicity, gender, national origin, religion, socioeconomic status, presenting problems, and level of problem severity. The instructor can have students simply read through these profiles and then complete the three sets of exercises that follow them.

  • Several new aspects have been highlighted: for example, a novel role for lipids as receptors which drive protein sorting, the diversity of the sorting events that occur at the level of the Golgi apparatus, and the cross talk between exocytosis and autophagy. Moreover, an interesting example of how the knowledge of these pathways is exploited to generate novel secretory routes to direct the synthesis of bio-molecules in “cell factories” is discussed.

  • The aim of this chapter is to summarize and evaluate the different mechanisms and catabolic mediators involved in cancer cachexia and ageing sarcopenia since they may represent targets for future promising clinical investigations. Cancer cachexia is a syndrome characterized by a marked weight loss, anorexia, asthenia and anemia. In fact, many patients who die with advanced cancer suffer from cachexia. The degree of cachexia is inversely correlated with the survival time of the patient and it always implies a poor prognosis.
