Flow Mediated Skin Fluorescence technique reveals remarkable effect of age on microcirculation and metabolic regulation in type 1 diabetes.

STUDY DESCRIPTION: Flow Mediated Skin Fluorescence (FMSF) is a novel technique for non-invasive evaluation of the microcirculation and metabolic regulation. This study describes the diagnostic potential of FMSF for type 1 diabetes (DM1). STUDY POPULATION: All study participants, in both the control (n = 31) and DM1 (n = 40) groups, were between the ages of 30-49 y. The patients in the DM1 group had all been suffering from diabetes for at least 10 y. RESULTS: The parameters HRindex, HRmax and MR inversely correlate with age and BMI. An unidentified compensatory effect was observed among the younger members of the DM1 group. The majority of DM1 patients with HRindex < 8% showed signs of dysfunctional metabolic regulation. CONCLUSION: FMSF appears to be an extremely useful technique for monitoring diabetic patients over time, enabling early diagnosis of potentially dysfunctional microcirculation and metabolic regulation.

[Physical activity of adult residents of Katowice and selected determinants of their occupational status and socio-economic characteristics]. / Aktywnosc fizyczna doroslych mieszkanców Katowic a wybrane uwarunkowania zawodowe i spoleczno-ekonomiczne.

BACKGROUND: The issue of physical activity (PA) is often addressed in the literature, but its socio-economic determinants are fully recognized. To date no studies of the adult population of Katowice have been carried out. Research in this area is of great importance in the context of the documented influence of PA on health and extension of retirement age in Poland. The aim of this paper is to evaluate the relationship between PA and socio-economic status of adult residents of Katowice. MATERIALS AND METHODS: The study carried out in 2010 comprised 2053 people (987 women and 1066 men) aged 30-65 years. To evaluate PA in the study group the diagnostic survey method and a research tool in the form of an abridged version of the International Physical Activity Questionnaire (IPAQ), with specification expanded by the authors, were used. In the statistical analysis logistic regression was employed. RESULTS: The likelihood of meeting the standards of health-enhancing PA was higher in men than in women and it decreased with age and education level of the respondents. The highest proportion of those meeting the recommendation of health-enhancing PA was observed among blue-collar workers, operators, teachers, police and soldiers. The lowest probability of meeting the recommendations of the American College of Sports Medicine was found among economists and lawyers, office workers, the unemployed, managers, and engineers, pensioners and health care professionals. CONCLUSIONS: The study demonstrates the correlation between PA and socio-economic status of the respondents. The analysis of the results indicates the necessity to promote PA programs mainly among women, the elderly, the unemployed, pensioners and representatives of professions, such as economists, lawyers, managers, engineers, and health professionals.
