Significant effect of group education in patients with diabetes type 1.

Objective: Type 1 diabetes mellitus (T1DM) constitutes a real challenge in everyday practice for both physicians and patients. Due to the complexity of the disease and its unpredictable nature, structured education and training programs are nowadays implemented that ensure active patient involvement and self-care behaviors to achieve adequate glycemic control, prevent diabetic complications, and improve the quality of life of patients. These programs provide patients with the necessary knowledge and skills to self-monitor and self-manage the disease and its associated metabolic conditions.

Hormonal anti-implantation agents: antiprogestins.

Oestrogens and progestogens separately or in combination are able to prevent implantation with high efficiency, thus acting as interceptive agents. Current interceptive medical regimens include high-dose oestrogens, the association of oestrogens with progestogens or progestogens alone. Compounds with antiprogesterone properties, such as RU 486 (mifepristone) or ZK 98734 (lilopristone), also exhibit a strong interceptive action which, as shown in animal models, is proportional to the dose and the day(s) of administration.

Displacement of receptivity for nidation in the rat by the progesterone antagonist RU 486: a scanning electron microscopy study.

In the rat, the period of receptivity for nidation (implantation window) is characterized by specific change of the apical surface of the luminal uterine epithelium, such as the presence of large ectoplasmic projections (pinopodes). Under the conditions of this study, fully developed pinopodes appeared during normal pseudopregnancy on day 5 only. When RU 486 (5 mg/kg s.
