Background Clinical experience indicates that patients declining participation in randomised clinical trials (RCTs) at the time of surgery are older, less healthy and of lower social status than patients accepting to participate, compromising the external validity of the RCT and bringing the non-participants in higher risk at surgery. To our knowledge, no studies exist on patients with hazardous

BACKGROUND: Integrated health promotion improves clinical outcomes after hospital treatment. The first step towards implementing evidence-based health promotion in hospitals is to estimate the need for health promoting activities directed at hospital patients. The aim of this study was to identify the distribution and association of individual health risk factors in a Norwegian hospital population

Introduction: Smoking is the most important risk factor for morbidity and mortality in hospital patients. Patient contact with the healthcare system should include smoking cessation counselling. Emergency admissions are seldom given this opportunity.Objective: The aim of the study was to illustrate the implementation of motivational counselling in a department of acute surgery.Methods: Between May

Morphological and optical properties of tentacular epidermis and cornea of the eyes of some species of terrestrial gastropod pulmonate molluscs were studied and their evolutionary transformations were estimated. It was demonstrated that all examined properties of tentacular epidermis and cornea of these species are typical for terrestrial pulmonates. In the course of evolution tentacular epidermis

There is considered a mean square convergence of a stochastic approximation algorithm, are derived, formelas of the asimptotical variances of the solution estimations, which are right for dependent observations as well, is defined optimal consequence of coefficients.

At the same time as our dependence on IT systems increases, the number of reports of problems caused by failures of critical IT systems has also increased. Today, almost every societal system or service, e.g., water supply, power supply, transportation, depends on IT systems, and failures of these systems have serious and negative effects on society. In general, public organizations are responsibl

Long hydrological records, from the Amazon Basin, northeastern Brazil, and northwestern Peru spanning most of this century, are examined for trends in rainfall (three wettest months) and runoff (three months of highest flow) or stage, where no rating curves exist. Trends are tested for significance using the Mann-Kendall statistic. In basins where large soil, aquifer, or man-made reservoirs give r
