About 4.5 million Americans have heart failure (HF). It is the most frequent cause of hospitalization for individuals older than 65 years. Some patients, with treatment, may lead nearly normal lives, whereas more than 50% of individuals with severe HF die each year. HF is a complex clinical syndrome that can result from any number of cardiac or metabolic disorders such as ischemic heart disease, hypertension, or hyperthyroidism. Any condition that impairs the ability of the ventricle to pump blood can lead to HF In HF, die heart... 

All explanations of addiction and policies on substances of abuse will have to confront the complex clinical realities. The development of addiction involves characteristic changes in motivation and self-control important both to the individual and to society. The frequency of drug taking is a central factor in this process but not the sole factor. Others relate to societal influences and others again to upbringing or biological dispositions. The clinical phenomenology is mostly described by concepts such... 

Although IEF of serum transferrin is relatively easy to perform, it is assumed that many CDG patients are still missed. Due to the complex clinical presentation of CDG, all patients suffering from unclear multi-organ diseases, especially in combination with mental and psychomotor retardation, strabismus, cerebellar atrophy and blood-clotting problems, should be investigated for CDG. 

The main limitation towards the widespread application of MIPs as selective recognition elements in ILAs is that their performance is still not as brilliant as their biological counterparts. Their sensitivity and selectivity in aqueous media is, in most cases, lower than that of the antibodies. In fact there are not many examples so far of ILAs for the analysis of complex clinical, environmental or food samples. Moreover, the number of MIP-based validated methods described in the literature is still limited and this issue should be addressed before these materials can be considered as practical alternatives to the biological recognition entities.

Enzymes with reasonably high substrate specificity are available, so it is possible to analyze the desired substance in the presence of many other substances. A tedious specimen preparation procedure is usually not required. Chemical analysis would frequently require such a step, particularly in complex clinical and industrial samples. 

Patients hospitalized in intensive care units (postoperative) often require the application of combination treatments (i.e., simultaneous use of different drugs). This situation is caused by the necessity of simultaneous control of complex clinical... 

One frequent point of confusion is whether a clinical rating scale/ such as the Hamilton Depression scale/ is a biomarker or a clinical endpoint. As these scales attempt to capture the multifaceted dimensions of a complex clinical condition/ they are in fact clinical endpoints. However/ they are like intermediate endpoints because they do not encompass all dimensions of the disease being evaluated or the therapeutic response in all patients.

Vitamin deficiencies are commonly multiple, and complex clinical pictures occur. There are numerous single and multivitamin preparations to provide prophylaxis and therapy.

While voltammetric/ainperometric techniques can be applied to detect a wide range of species, the selectivity offered for measurements in complex clinical samples— where many species can be electroactive—is rather limited. For example, as stated in the above discussion relevant to the Clark oxygen sensor, in the absence of the gas-permeable membrane, other species that can be reduced at or near the same Eappi as oxygen would cause significant interference. 

The perspective from which an economic evaluation is performed affects the design, conduct, and results of the evaluation. The perspective may, for example, be that of a patient, a payer (government health agency or health insurance company), or society. The perspective may be long term or short term. The perspective is a practical consideration when attempting to assess the benefit of a particular test or device as part of a more complex clinical protocol. Perspective is also important in relation to many of the routine decisions made about a diagnostic test. The questions below illustrate the importance of perspective ... 

We have not sought in this chapter to describe phase I studies as such. This is a postgraduate textbook, and we wish to convey how in vitro and in vivo data of various kinds may be used to help extrapolate observed drug effects from simple experimental systems to the more complex clinical situation. The ultimate need is to obtain useful predictions of response in healthy human subjects (phase I studies) from observed drug effects in animals or in the test tube. 

Stochastic simulation was another step forward in the arena of pharmacometrics. Simulation had been widely used in the aerospace industry, engineering, and econometrics prior to its application in pharmacometrics. Simulation of clinical trials first appeared in the clinical pharmacology hterature in 1971 (40) but has only recently gained momentum as a useful tool for examining the power, efficiency, robustness, and informativeness of complex clinical trial structure (41).
