- Before commissioning of a nuclear facility it is important to determine the baseline of the radiation environment. Such baseline or Zero Point assessments can only,and uniquely, be made before start of operation of the facility and will serve several purposes when the facility is in operation. Here we report on the planning and implementation of such a Zero Point program for achieving high reproducibility and effectiveness of the assessments around two nuclear installations.

- Background:The assessment of lower limb volume by circumferential measurements every 4th cm along the limb is common inlymphedema management. In recent years, also measurements of local tissue water by Tissue Dielectric Constant (TDC) of the skinusing a MoistureMeterD have been applied more frequently. There are very few studies assessing the reliability of these methods.Aim of the work: To evaluate the test-retest reliability of lower limb volume and local tissue water by TDC values in healthy womenand men, and to define limits that indicate real changes over time.Material & methods: In total, 33 women and 28 men completed the measurements. Inclusion criteria was 18 years or older, with astratified variety in age, and with no previous lower limb swelling. Both legs were measured by the same rater (CJ), at two occasions, 2weeks apart, preferable in the morning. Circumferential measurements every 4th cm along the limb were used to calculate the volume,and measurements of local tissue water were taken at 14 predefined points, using TDC.Statistical methods: To evaluate the reliability agreements between measurements (ICC2,1), systematic changes in the mean, thestandard of measurement (SEM and SEM%) and the smallest real difference (SRD and SRD%) were used. The SEM% gives themeasurement variability in relative values and represents the limit for the smallest change that indicates a real change for a group ofsubjects. The SRD% represents the limit for the smallest change that indicates a real change for a single subject.Results: For the volume, the reliability was excellent (ICC2,1 0.99) and the mean difference was low for both women and men. Asystematic difference was seen only in the left limb in men. The SEM% was 1.3% and the SRD% was 3.6%. For the TDCmeasurements, the ICC2,1 ranged from 0.63 to 0.93 in women and from 0.21 to 0.89 in men. The mean difference was low. Somesmall systematic differences in the mean were found in a few points. The SEM% ranged from 3.9% to 10.2% in women and from 3.9%to 14.5% in men. The SRD% ranged from 10.8% to 28.2% in women and from 10.9% to 40.1% in men.Conclusions: Lower limb volume and TDC measurements can be reliable measured in healthy subjects. Small changes in volume willindicate real clinical changes for a group of subjects as well as for single subjects. Relatively small changes in TDC values in all pointsin women and in all but 3 points in men, will indicate real clinical changes for a group of subjects as well as for single subjects.

- Background: Consumption of polyphenol-rich fruits and vegetables may improve postprandial glucose and insulin levels and hence promote well-being. Previously it has been observed that consumption of bilberry decreases the postprandial insulin demand. The intention with the present study was to compare the impact of different supplements with various polyphenol profiles, on the postprandial glucose and insulin responses in healthy young adults. Methods: In a randomized, controlled, crossover study the postprandial glycemic and insulin responses were observed in eleven healthy adults after intake of five different beverages containing bilberry (European blueberry), blackcurrant, beetroot, mango and rose hip, respectively; all drinks were enriched with the same composition of fermented oatmeal and probiotics. The control was a glucose drink. The profile and content of the polyphenols in the different beverages were determined by HPLC-DAD analysis. The antioxidative capacity of the different beverages were measured by TEAC and DPPH assays. Results: Beverages containing bilberry, blackcurrant, mango or rose hip significantly attenuated the early postprandial insulin response (0-90 min), but showed no effect on glucose response. Drinks with bilberry or rose hip reduced the insulin response from the very early phase (0-30 min), and had significantly lower insulin index compared with the control. The efficiency of the bilberry and rose hip to decrease early postprandial insulin responses correlated with higher phenolic contents. Conclusions: Supplements with bilberry, blackcurrant, mango or rose hip in the tested probiotic and oatmeal enriched beverage attenuated early-phase insulin response, but had no effect on the postprandial glycemic response. The improved ability of bilberry and rose hip to lower the very early phase of insulin response seems to be due to a higher phenolic content. Trial registration: The study was retrospectively registered at ClinicalTrials.gov with number NCT03159065.
