Several recent studies suggest that individual subjective survival forecasts are powerful predictors of both mortality and behavior. Using 15 years of longitudinal data from the Health and Retirement Study, I present an alternative view. Across a wide range of ages, predictions of in-sample mortality rates based on subjective forecasts are substantially less accurate than predictions based on p...

background: life expectancy at birth as an alternative summary measure of mortality represents number of years which a newborn will be alive based on the current age specific death rates. as it summarizes death rates across all age range in a given population is the most common summary measure of mortality. the aim of this study was to correct death rates for underreport and estimate life expec...

background and purpose: acute physiology and chronic health evaluation (apache ii) is a scoring system that describes and predicts the severity of acute illness in patients admitted in intensive care units. its application is helpful in therapeutic monitoring methods, comparing the effectiveness of treatments and the decision to change the treatment, and comparing the performance and quality of...

According to our model of aetiology SIDS occurs by a deficiency of neurotransmitters (NT): acetylcholine (Ach), serotonin (5-HT), dopamine (DA) and, above all, orexin (OX); this shortage is caused by the poor functioning of the mesencephalic trigeminal nucleus (Me5) [1], due to the physiological lack of teeth in this period of life, which normally stimulates the nuclei manufacturers of the afor...

In general, the incidence of diabetes mellitus is high in societies that consume little carbohydrate and is low in countries where carbohydrate consumption is high. Himsworth reported that the consumption of the diet might be an influential factor in the etiology of diabetes mellitus and the high fat consumption was most closely related with high mortality rate of diabetes(1). In this study, we...

Two large clinical trials of drugs that exhibited significant antiarrhythmic properties in single cells were found to increase the rate of sudden cardiac death in patients by two to three fold over untreated patients. We hypothesized that premature excitation within the drug-altered vulnerable region, a region that trails each excitation wave, might be one mechanism for initiating re-entrant ta...
