[There is plethora of international publications on the topic of burnout among health professionals. The most comprehensive study in Hungarian on this issue was written fifteen years ago by psychiatrist Sandor Fekete. In the past fifteen years there has been a growing interest among both the scientific community and the public in studies on health psychology, behavioural sciences, sociology of health and quality of life as well as in the harmful effects of work stress. The first part of the study presents clarification of the concept of burnout, its development, course, assessment and treatment, whereas the second part gives a brief overview of the history of burnout research in the past thirty years with special focus on the most recent international and Hungarian literature, as well as on changes in research trends.]

[Obesity affects a significant proportion of the population in Western countries. Metabolic changes that are associated with obesity lead to metabolic syndrome, a significant risk factor of cardiovascular mortality. Body mass index, which is used to describe the extent of obesity, is not suitable on its own to predict cardiovascular risk or assess metabolic changes, because it doesn't provide information on the distribution of accumulated fat within the body. Several studies have shown that it is the central/abdominal/visceral type of obesity that significantly increases cardiovascular morbidity and mortality. Visceral and subcutaneous fat tissue differ both in their function and the biological effects of adipocytokines secreted by them. Apart from the known effects of free fatty acids on insulin resistance and consequently to other metabolic parameters, adipocyte-derived adipokines have been shown to have a beneficial, antiatherosclerotic effect. In order to precisely estimate the obesity-related cardiovascular risk in everyday practice, not only body mass index, but waist circumference, a marker of visceral obesity, should also be measured.]
