We conducted a randomized controlled trial to examine the effect of two energy-restricted diets on body weight (BW), visceral fat (VF) loss, and the risk factors for metabolic syndrome. A total of 144 centrally obese postmenopausal women were assigned to the moderate in fat Mediterranean diet (MED) or to the Central European diet (CED), which is moderate in carbohydrates and high in dietary fiber (DF), for 16 weeks. BW, waist circumference and VF were significantly reduced by 8.8%, 7.0%, and 24.6%, respectively, over the trial (P < 0.001), with no difference between groups. A similar trend was seen for total cholesterol, triglycerides, glucose, and blood pressure. Within each diet group, the more adherent participants lost significantly more BW than did their less adherent counterparts. VF was significantly reduced only in women who were more adherent to the CED, and the reduction in VF correlated with an increase in the proportion of DF. Short-term dietary treatment with the CED or the MED was associated with similar improvements in some anthropometric, lipid, and nonlipid parameters; however, adequate adherence to the prescribed diet is important in weight loss success and in achieving improvements in metabolic health.

Cystic fibrosis (CF) patients are at high risk for vitamin K deficiency. The effects of vitamin K supplementation are very ambiguous. Therefore, we aimed to define the determinants of vitamin K deficiency in a large cohort of supplemented - 146 (86.9%) and non-supplemented - 22 (13.1%) CF patients. Vitamin K status was assessed using prothrombin inducted by vitamin K absence (PIVKA-II) and undercarboxylated osteocalcin (u-OC). The pathological PIVKA-II concentration (≥2 ng/ml) and abnormal percentage of osteocalcin (≥20%) were found in 72 (42.8%) and 60 (35.7%) subjects, respectively. We found that liver involvement, diabetes, and glucocorticoid therapy were potential risk factors for vitamin K deficiency. Pathological concentrations of PIVKA-II occurred more frequently in patients with pancreatic insufficiency and those who have two severe mutations in both alleles of the CFTR gene. Pathological percentage of u-OC was found more frequently in adult CF patients and those not receiving vitamin K. However, it seems that there are no good predictive factors of vitamin K deficiency in CF patients in everyday clinical care. Early vitamin K supplementation in CF patients seems to be warranted. It is impossible to clearly determine the supplementation dose. Therefore, constant monitoring of vitamin K status seems to be justified.

Objectives: It is the prospective observational study aimed at early prediction of pregnancy complications in women with symptoms of MS. Material and methods:124 Caucasian women in singleton pregnancies 11 th to the 13 th wks 6 days of gestation with MS criteria compared to 30 healthy controls. Perinatal maternal and fetal results were analyzed.Results: Increased in the MS group were: age (32.9 y vs. 28.6 y; p = 0,00), weight 11 to 13 + 6 weeks of gestation (79. Conclusions:Higher E-selectin serum concentration, GGTP and lower SHBG in the first trimester are additionally to fasting maternal glucose, higher BMI and maternal age predictive for GDM. Higher E-selectin, fasting glucose, increased BMI and lower adiponectin serum concentration in the first trimester are significant predictors of fetal macrosomia. Maternal BMI > 24.5 kg/m 2 is the best predictor of increased risk of fetal macrosomia and gestational diabetes mellitus.

The crucial method of minimizing the development of atherosclerosis and its clinical manifestations is lifestyle modifications, including following a healthy diet. The aim of the study was to check if the Central European Diet (CED) could be an alternative to the Mediterranean Diet (MED) in the prevention of AT in patients with a risk of MS. Methods. The randomized, single-blind nutritional trial involved 144 obese women with a risk of MS. The subjects were randomly assigned to two groups and followed MED (n = 72) or CED (n = 72) for 16 weeks. The concentrations of high-sensitivity C-reactive protein (hs-CRP) and asymmetrical dimethylarginine (ADMA) were measured before and after nutritional intervention. Results. In both studied groups, the concentrations of hs-CRP decreased significantly after the nutritional intervention (CED: p = 0.0107; MED: p = 0.0002). The ADMA levels were significantly lower after nutritional intervention in the CED group (p = 0.0187) but not in the MED group (p = 0.8354). However, the observed changes of hs-CRP concentrations (Δhs-CRP) and ADMA levels (ΔADMA) were not different between the groups (p = 0.5307 and p = 0.0905, respectively). Conclusion. In the Central European post-menopausal obese population, a well-designed, energy-restricted diet with the use of food items traditional for the region (CED) could be a good alternative to MED in terms of AT prevention.
