Analytic Function of Diffusion-Weighted as well as Powerful Contrast-Enhanced Perfusion Mister Image in Paragangliomas and Schwannomas in the Head and Neck.
An adverse relationship between both GL and GL/1,000 kcal and level of education was found. The percentage of females, urban inhabitants, people with university education and not married decreased with quartiles of the overall dietary GL and GL/1,000 kcal. The percentage of former smokers, people who never used alcohol and people with low and moderate physical activity decreased with quartiles of GL and GL/1,000 kcal. Lower percentage of individuals aged 44-64 years was observed with quartiles of the overall dietary GL. CONCLUSIONS Factors such as male gender, rural place of residence, low level of education and smoking determine the group of people that is the most exposed on the effects of improper nutrition, according to the low quality and/or high amount of carbohydrates defined by GL and GL per 1,000 kcal.INTRODUCTION AND OBJECTIVE The male reproductive system constitutes a set of tissues which are particularly sensitive to external factors. The aim of the study was to analyze the relationship between background radioactivity and the quality of the semen of the men who have reported to the infertility treatment facility in 2000-2016 in the Lublin region of eastern Poland. MATERIAL AND METHODS The radioactivity of the ground-level air layer obtained from the Institute of Meteorology and Water Management in Włodawa in the Lublin region was analysed. 4,250 spermiograms of patients who reported to the treatment facility for the first time due to infertility were analysed and correlated to background radioactivity in the Lublin region in 2000-2016. RESULTS A long-term decrease in the percentage of morphologically normal spermatozoa of the patients was observed (r=-0.970; p less then 0.001 in 2000-2009 and r=-0.925; p=0.003 in 2010-2016). Men's age correlated negatively with sperm motility (r=-0.164; p=0.009) and morphology (r=-0.186; p=0.009). The percentage of spermatozoa with normal morphology was lowered by beta-isotopes of artificial origin in the air in 2000-2009 (r=-0.655; p=0.040) and by the exposure to gamma radiation of the ground-level atmosphere in 2010-2016 (r=-0.676; p=0.048). The percentage of sperm vitality was lowered by gamma radiation in the atmosphere (r=-0.636; p=0.006), but improved by beta isotopes in precipitation (r=0.686; p=0.002) in the whole of the analyzed period. CONCLUSIONS The percentage of morphologically normal spermatozoa in patients who reported to the infertility treatment depends not only on the age of patient, but also on beta-isotopes of artificial origin and gamma radiation in the atmosphere. Beta isotopes in precipitation affect the improvement of sperm vitality.INTRODUCTION AND OBJECTIVE Back pain affects specific occupational groups, among which healthcare workers are the most predisposed. Therefore, the aim of this study was to determine the interdependences between subjective disability and their correlation with pain intensity and quality of life assessment among professionally active medical workers, taking into account working, socio-demographic and health conditions. MATERIAL AND METHODS The cross-sectional study enrolled 110 professionally active medical workers (nurses, midwives, paramedics and physiotherapists). The study was conducted by a diagnostic survey method using 4 questionnaires Visual Analogue Scale (VAS), Oswestry Disability Index (ODI), World Health Organization Quality of Life BREF (WHOQoL-BREF), and the authors' questionnaire. RESULTS Back pain was reported by 103 respondents (94%) with the lumbar area indicated the most frequently (72.81%). Severe pain every day was reported by 49.51% of respondents and was associated with longer working time. ODI questionnaire confirmed III and IV degrees of disability in paramedics and nurses, who additionally obtained the lowest results in the quality of life assessment. Correlations between age and VAS were demonstrated (p=0.002), and between VAS and ODI pain (p less then 0.0001) and ODI disability (p less then 0.0001). CONCLUSIONS Back pain associated with professional activities is the consequence of overload. Health care workers should be included in a preventive programme and attend systematic ergonomics courses. Health care facilities should be retrofitted with equipment enabling work in accordance with the principles of ergonomics. The ODI questionnaire, together with the VAS method and scales for testing the quality of life, are useful tools in the clinical assessment of individuals with back pain.INTRODUCTION AND OBJECTIVE Contamination of soil by mercury poses several risks to human health through consumption of fruits and vegetables. In Slovakia, a high concentration of mercury is found in the soil of the Central Spiš region. The objective of the study is to measure the mercury concentrations in the parts of selected plant species and trees growing within 100 meters of a former ore processing facility. MATERIAL AND METHODS A total of 24 samples of plants, 20 samples of parts of needle-leaved trees and 9 samples of parts of broad-leaved trees were collected from soils with a high concentration of mercury. The concentration was measured by atomic absorption spectrometry in different parts of the plants leaves - 18 species, roots - 15 species, stems - 11 species, flowers - 7 species), and different parts of trees (crust - 8 species, branches - 8 species, needles - 5 species, cones - 5 species, leaves - 3 species). RESULTS The concentrations of mercury in the soils taken at a depth of 0.25 m exceeded the maximum allowed levels more than 50-times. Potatoes, parsley and carrots from these soils exceeded the maximum allowed mercury levels 6-times, 5-times and twice, respectively. The average concentrations of mercury in the roots of 2-year onions exceeded the limit more than 50-times. The flowers of cornflower contain 18.20 mg*kg . learn more CONCLUSIONS The systematic monitoring of mercury is still very important, since it was found that the end of ore processing does not solve the issue of contamination in the Central Spiš region. Therefore, the consumption of fruits and vegetables from the areas of former ore processing facilities is not recommended.
