Perioperatory pain in oncological patients represents a witness of anesthetic-surgical aggression, frequently exacerbated by the complementary radio-chemotherapy and also a predictive factor for postoperatory evolution. The objectivation of perioperative pain by scales of clinical evaluation does not offer a certain and objective quantification; so, the dosing of some hormonal and acute phase i...

OBJECTIVES Limited information is available concerning the post-treatment neutrophil-lymphocyte ratio in critical limb ischemia patients who receive conservative therapy. Accordingly, this study was designed to evaluate the predictive value of the post-treatment neutrophil-lymphocyte ratio in critical limb ischemia patients without surgery. METHOD From January 2009 to January 2011, critical l...

While DeKalb County, Georgia, offers free radon screening for all eligible residents, portions of the county remain relatively under-sampled. This pilot study focused on 10% of the census tracts in the county with the lowest proportion of radon testing; most were in southern DeKalb County. In total, 217 households were recruited and homes were tested for indoor radon concentrations on the lowes...

The collapse of the World Trade Center (WTC) on 11 September 2001 exposed New York City firefighters to smoke and dust of unprecedented magnitude and duration. The chemicals and the concentrations produced from any fire are difficult to predict, but estimates of internal dose exposures can be assessed by the biological monitoring of blood and urine. We analyzed blood and urine specimens obtaine...

BACKGROUND AND PURPOSE Statistical models to predict the outcome of stroke patients have several uses. Their utility depends on their predictive accuracy in patients other than those on whom they were developed (ie, external validity). We sought to test the external validity of some recently described models in patients enrolled in the FOOD (Feed Or Ordinary Diet) trial: a large randomized tria...

An important application of regression methodology is in the area of prediction. Oftentimes investigators are interested in predicting a value of a response variable (Y) based on the known value of the predictor variable (X). However, sometimes there is a need to predict a value of the predictor variable (X) based on the known value of the response variable (Y). In such situations, it is improp...

BACKGROUND It is important to obtain greater insight into health-related quality of life (HRQL) of injury patients in order to document people's pathways to recovery and to quantify the impact of injury on population health over time. We performed a systematic review of studies measuring HRQL in general injury populations with a generic health state measure to summarize existing knowledge. ME...

A personal best marathon time has been reported as a strong predictor variable for an Ironman race time in recreational female Ironman triathletes. This raises the question whether recreational female Ironman triathletes are similar to recreational female marathoners. We investigated similarities and differences in anthropometry and training between 53 recreational female Ironman triathletes ...

The influence of 18 predictive variables on final match result in the character of the criterion variable has been analyzed for the purpose to establish the significance of positional direction of the attack end conduction on the situation-related resulting successfulness in top quality handball. It has been done on the sample of 80 matches from 1999 Men's World Handball Championship in Egypt. ...

Research findings indicate that there are multiple causal pathways to delinquency. A multicomponent model of delinquency was developed to explore systematically the interrelationships of psychosocial variables and their relationships to delinquent behaviour. Most importantly, alienation was tested for its ability to act as a core mediating predictor variable. One hundred and fifty-two adolescen...
