The aim of the study is to analyse changes in the size of the population of nurses in Poland in the years 2004-2014, considering changes in their employment and the phenomenon of ageing. The analysis is based on the data published by the Central Register of Nurses and Midwives of the Central Statistical Office (GUS) and the Organisation for Economic Co-operation and Development (OECD). Nurses are the largest professional group in the healthcare sector. In 2014, only above 70% of licensed nurses were professionally active. The percentage of employed nurses compared to the number of licensed nurses varied between the lowest ratio of 65.1% in 2005 and the highest ratio of 71.7% in 2012. The latest ratio of 2014 was 70.9%, which was slightly lower compared to the highest ratio in 2012. The average age of a Polish nurse in 2008 was 44.19 years, increasing by about six years to 50.1 within the analysed period. The population of nurses aged above 65 years is almost 4.5 times bigger compared to the youngest age group, which is 21-25 years. Thus, 2/3 of the population of nurses are 41-60 years of age and nearly 85% are over 40. For two years (2000 and 2014), the number of practising nurses per 1000 inhabitants places Poland in the fifth bottom position among the European countries, which shows a significant reduction in patient access to nursing services. In Poland, the profession of nurses has no replacement generation. The article presents the shortage of professionally active nurses in Poland. The existing register of nurses does not contain complete information necessary to evaluate the current situation in Poland. There is a strong need to improve the tracking system of the register of nurses to accurately monitor the number of nurses in Poland The shortage of professionally active nurses and their ageing necessitates immediate action to reduce the shortage by increasing the appeal of the profession among young people and by encouraging nurses to return to the profession. It is also necessary to take action to delay the retirement of those nurses who want to work longer and to use their potential. This is also particularly important because of the gap in experience, which is going to become apparent the nearest future.

The prevalence of erectile dysfunction (ED) in men visiting outpatient clinics was analyzed using data reported by 1352 randomly chosen physicians who were requested to interview five to 20 consecutive patients aged X40 years about the presence of ED. A total of 25.12% of the physicians returned the questionnaires, containing data on 3552 patients, of whom 42.7% had ED, 44.9% had no ED and 12.4% declined to answer the questions. The duration of ED was o1 year in 8.1% of patients, 1-2 years in 32.2% and 42 years in 59.7% of patients. 86.4% of men with ED had X1 chronic disease. ED was present in 70.3% of men with coronary heart disease, 67.8% of those with hypertension, 78% of those with diabetes and 70.5% of patients with psychiatric diseases. 93.2% of patients with ED used one or more drugs chronically. In conclusions, 42.7% of men visiting outpatient clinics had ED. Patients with ED often had one or more chronic diseases and used at least one drug chronically. Older patients are less inclined to talk to their physicians about sexual problems.

During fetal life, placental tissue represents an additional source of leptin for the mother and conceptus. It has been suggested that feto-placental production of leptin may be involved in placental and fetal growth regulation. The aim of this study was to examine the correlation between leptin mRNA expression in the placenta and the concentrations of leptin in cord blood. A total of 30 healthy, pregnant women who gave birth to healthy neonates were included in the study. Maternal blood (obtained from the cubital vein) and umbilical cord blood were drawn immediately after birth. Serum leptin concentration was determined by enzyme-linked immunosorbent assay and serum insulin concentration was measured by radioimmunoassay. Leptin mRNA was measured in placental tissue by a reverse transcriptase-polymerase chain reaction. The estimated mean leptin mRNA expression in placenta was 4.65 +/- 1.83 pg mRNA/microg DNA. Leptin mRNA correlated with cord serum leptin concentrations (r = 0.3691, p = 0.045). Placental weight correlated with placental leptin mRNA (r = 0.3686, p = 0.045). The mean leptin concentration in cord serum at birth was slightly lower (3.1 +/- 1.9 ng/ml) than that found in maternal serum (3.9 +/- 1.2 ng/ml). A positive correlation was observed between cord and maternal serum leptin levels (r = 0.58, p = 0.001). The mean insulin concentration in maternal serum was not significantly higher than that in umbilical serum: 22.2 +/- 17.8 microIU/ml vs. 6.9 +/- 3.6 microIU/ml; r = 0.069, p = 0.71). Neither maternal nor umbilical insulin concentrations correlated with leptin concentration in cord or maternal peripheral serum.
