Why does healthcare of breast cancer (BC) patients, especially in a young population, matter and why are innovative strategies by predictive, preventive, and personalized medicine (PPPM) strongly recommended to replace current reactive medical approach in BC management? Permanent increase in annual numbers of new BC cases with particularly quick growth of premenopausal BC patients, an absence of clearly described risk factors for those patients, as well as established screening tools and programs represent important reasons to focus on BC in young women. Moreover, "young" BC cases are frequently "asymptomatic", difficult to diagnose, and to treat effectively on time. The objective of this article is to update the knowledge on BC in young females, its unique molecular signature, newest concepts in diagnostics and therapy, and to highlight the concepts of predictive, preventive, and personalized medicine with a well-acknowledged potential to advance the overall disease management.

In our experimental study we found that the participation of BK(Ca2+) and K(ATP) potassium ion channels in the contractility of human term pregnant myometrium in labor is probably different.

Objective: The purpose of this study was to examine plasma levels of fibronectin and plasminogen inhibitor type 1 (PAI-1), and alterations in uterine artery (UtA) waveforms throughout normotensive and preeclamptic pregnancies and to analyze its predictive value for the detection of preeclampsia within the second trimester of pregnancy.Material and methods: Blood samples were collected from 102 healthy, nulliparous women between the 24th and 26th gestational week. Preeclampsia developed in 13 patients; 89 normotensive control subjects were matched from the same cohort. Plasma samples were assayed for fibronectin and PAI-1 by enzyme-linked immunosorbent assay. Color pulsed Doppler examinations of UtA were performed after blood sampling. Trends were compared between two groups.Results: Maternal plasma fibronectin and PAI-1 levels and average PI, RI and S/D ratios of patients with preeclampsia were significantly higher (p < 0.05). The best cut-off values for predicting preeclampsia of fibronectin, PAI-1, PI, RI, S/D ratio based on ROC curve analysis were 290 mg/ml, 77.3 ng/ml, 1,0615, 0.605 and 2,59 respectively. The areas under the curve equal to 0.705, 0.753, 0.689, 0.695 and 0.699 for fibronectin, PAI-1 and uterine artery Doppler PI, RI, S/D ratio were determined for the prediction of preeclampsia.Conclusions: Fibronectin, PAI-1 and UtA Doppler are potentially useful predictors of preeclampsia. Maternal plasma PAI-1 combinated with fibronectin had the highest predictive values in our study.

Our data are consistent with previous studies of the enhanced efficiency of the beta(2)-adrenergic agonist, when administered together with the phosphodiesterase 4-inhibitor. Moreover we have shown that rolipram alone has a more profound effect on oxytocin-induced contractions than salbutamol alone.
