Drug adverse events and drop-out risk: a clinical case.

We report a brief discussion on a clinical case of a female patient, 85 years old, affected by severe cognitive impairment and chronic obstructive pulmonary disease (COPD). The patient was not taking drugs at home (apart from promazine: 10 drops when necessary to control her behavioral diseases). A previous neuropsychological evaluation had shown a severe cognitive impairment MMSE=16/30; ADL=3/6; IADL=0/8) due to multiple brain ischemic areas (confirmed in 2003 by MRI neuroimaging).

Mortality rates and antihypertensive therapy in extreme old age.

The impact of hypertension on survival in extremely old age has shown different features in different studies, with equal or lower mortality rates in hypertensive patients and lower reduction of risk in treated patients. In a population (n=414) of old community dwellers (mean age 88.4 years) the prevalence of hypertension was 52.

Neural network analysis in predicting 2-year survival in elderly people: a new statistical-mathematical approach.

We designed this study to test the usefulness of artificial neural networks (ANN) in assessing 2-year survival in elderly persons, and to understand the net's logical functioning, thus determining the relative importance of the single biological and clinical variables which influence survival. ANN are statistical-mathematical tools able to determine the existence of a correlation between series of data and, once 'trained', to predict output data given input data. Although ANN have been applied in various areas of medical research, they have only very recently been applied in geriatrics (Cacciafesta et al.

A neural network study of the correlation between metabolic-cardiovascular diseases and disability in elderly people.

Numerous studies have affirmed the existence of a correlation between various cardiovascular diseases and functional decline in elderly people. Not much information, however, is available concerning the overall effect of various, possibly coexisting, cardiovascular pathologies, or metabolic conditions notoriously related to them, on determining disability. We wanted to verify if it were possible to assess: (1) The overall importance of various metabolic and cardiovascular diseases which elderly people often suffer from contemporaneously in determining a condition of not self-sufficiency; (2) The possibility of predicting a condition of not self-sufficiency in relation to the above-mentioned pathologies.

[Isolated systolic hypertension in the aged].

The prevalence of isolated systolic hypertension (ISH) is age-related. Its connection with the demographic shift experienced during the last century, results in an outstanding role, mainly as risk factor for most disabling diseases such as stroke. Epidemiological research suggests a high prevalence of the disease and--since the cut-off for hypertension has been lowered by the Joint National Committee--figures of the problem are, at the moment, probably underestimated.
