Opis:
Introduction. The sharp decline in the total fertility rate in Poland coincided with broader socio-economic changes, which resulted in its reduction to the lowest level observed among the countries of Central and Eastern Europe. Objective. The aim of the study was to investigate and evaluate the changing patterns of reproductive behaviour in rural and urban areas, depending on the demographic and socio-economic features in Poland. Materials and method. Information about live births in Poland in the years 1995–2014 were obtained from the Central Statistical Office. Registered cases of live births in rural and urban areas were analyzed considering the maternal features (age, marital status, main source of income). To evaluate the changes in fertility and comparisons between rural and urban areas, Joinpoint Regresssion was used. Results. In 1995–2014, a shift in the age of highest fertility from 20–24 years to 25–29 years was observed. This occurred at the same time as a reduction in the fertility rate per 1,000 women aged 15–29 years, more pronounced in rural areas (95.8 to 60.0) than in urban areas (63.4 to 51.5), while in women aged 30–49 years, a faster increase in fertility was observed in urban areas (16.4 to 32.0) than in rural areas (27.5–29.2). Fertility trends between rural and urban areas differed significantly. A significant increase in live births for employed mothers was shown mainly in 2005–2009; later, the growth rate in rural areas was slower and in urban areas the growth trend stopped. Conclusion. The postponement of births and reduction of fertility in women aged 15–29 requires active measures aimed at creating favourable conditions for achieving economic independence for the younger generation, as well as combining work with raising children, especially in rural areas.

Introduction and objective. Data on the possible role of peritoneal fluid free radical-mediated oxidative damage in the pathogenesis of endometriosis still remains inconsistent. The aim of the study was to determine iron metabolism markers and their influence on oxidative stress parameters in the peritoneal fluid of women with endometriosis. Materials and method. 110 women with endometriosis and 119 patients with benign ovarian cysts were included in the study. All visible peritoneal fluid was aspirated during laparoscopy from the anterior and posterior cul-de-sacs. under direct vision to avoid blood contamination. Haemoglobin, iron, total oxidative status, and total antioxidant status were measured using standard colourimetric kits. Results. Haemoglobin, iron levels, as well as total oxidative status values were significantly higher, whereas total antioxidant status values were significantly lower in the peritoneal fluid of patients with endometriosis, in comparison to the reference groups. No differences were observed in peritoneal fluid concentrations of all parameters measured in relation to the phase of the menstrual cycle. Conclusions. Peritoneal fluid of women with endometriosis is characterized by disrupted iron metabolism. This is most likely related to an increased number of erythrocytes in the peritoneal cavity of endometriotic women, which leads to a higher concentration of haemoglobin in this environment. Impaired iron homeostasis may have a significant influence on the pathophysiology of peritoneal endometriosis by the direct impact of haemoglobin derivatives and/or formation of the pro-inflammatory and pro-oxidative environment. Peritoneal cavity oxidative stress occurs predominantly in women in advanced stages of the disease.

Opis:
Introduction. Overweight and obesity, as well as a gonadal function, are pivotal factors influencing bone tissue metabolism. Materials and method. The aim of the study was to determine the effect of dietary induced obesity (DIO) on bone tissue metabolism in sham-operated (SHO) or ovariectomized (OVX) adult female Wistar rats. Additionally, the influence of DIO in SHO or OVX on the concentration of sclerostin in the blood serum was analyzed. After SHO or OVX, the rats were placed in groups (n=8) and either received a standard diet (11.5 MJ/kg) (SHO-CON; OVX-CON) or a high-energy diet (17.6 MJ/kg) (SHO-FAT; OVX-FAT). The experiment lasted for 90 days and allowed for the establishment of osteopenia in OVX females and obesity in the rats that had received the high-energy diet. Results. The results of the study demonstrate that obesity or/and ovariectomy increases the resorption of femora and tibiae, hence decreasing the densitometric and mechanical parameters affecting the bone structure in adult females rats. The strongest osteodegenerative effect was seen in the OVX-FAT females. Interestingly, the degree of bone tissue degradation caused exclusively by ovariectomy was similar to that found in the obese sham-operated rats. Conclusions. Bone losses invoked by DIO seem to be independent from the Wnt/β-catenin pathway inhibition induced by sclerostin. While further study is necessary, the obtained results suggest that the usage of sclerostin anti-body in the treatment of osteoporosis can be ineffective, and in obese patients the undertaking of such therapy should be reassessed.
