Objective: The aim of this study was to assess cardiometabolic risk factors and cardiovascular (CV) risk in the early period after pregnancy complicated by gestational diabetes mellitus (GDM). Materials and methods: Traditional (blood pressure, cholesterol and glucose levels, body mass index, smoking and other) and non-traditional [intima-media thickness (IMT), high-sensitivity C-reactive protein (hsCRP), oxidized low-density lipoproteins (LDL) and homocysteine levels] cardiovascular risk factors were assessed in early (6-12 weeks) postpartum period in 48 women after pregnancy complicated with GDM and in 12 women after uncomplicated pregnancy. The clustering of CV risk factors was assessed, as well as relative cardiovascular risk (according to the guidelines of European Society of Cardiology). Results: There were no significant differences between both groups with regard to the examined risk factors, with the exception of high-density lipoprotein (HDL) cholesterol level, which was within the norm range in all patients after uncomplicated pregnancy, but only in less than 60% patients after GDM. There were also no difference between the groups in mean number of cardiovascular risk factors or in proportion of patients having 1 or 2, or 3, or = 4 risk factor. Similarly, there was no differences in proportion of patients with different relative cardiovascular risk score. Prevalence of IFG, IGT and DM in the post-GDM group was 13.3%. Conclusions: In women with GDM in the early postpartum period the prevalence of CV risk factors and CV risk itself is similar to women after non-complicated pregnancy (the only exception was the low HDL cholesterol level and more prevalent carbohydrate metabolism disturbances in the former group).

Chemical Oxygen Demand (COD) solubilisation was used to evaluate the impact of thermal pretreatment on the transfer of sewage sludge from particulate to soluble phase. It was gathering the experimental data needed for building of empirical mathematical model describing the relation between applied temperature and time and rate of COD solubilisation and degradation. In view of repeated measurements, in order to describe the relationship between changes in the fraction of dissolved COD and the time and temperature, mixed models have been adopted where by fixed factor measurement conditions have been adopted: time and temperature, while the random factor changes the characteristics of waste activated sludge. Linear and logistic nonlinear mixed models were analyzed. The tests demonstrated that all variables are statistically significant in assessing their impact on the efficiency of liquefaction of sludge. On the basis of the estimated model, the temperature rise of 10°C increases degree of disintegration 1.7% above the average treatment time for 0.5h, by 2.6% for 1 hour, and by 3.9% for 2h. COD values decrease between 3 to 23% at temperatures in the range of 55 to 115°C. At higher temperatures COD was reduced in the range of 32 to 44%. Disintegration time did not have the significant impact on the degradation effect.
