Method: Questionnaire investigation, external genital examination and laboratory examination were conducted on 322 male peasants, including the exposed and the control groups of 161 subjects each. Results: Multivariate analysis showed that the educational level and the years of alcohol drinking influenced the semen volume. Compared with subjects of primary school education or lower, those with junior high school education had a higher semen volume (OR=1.961). Proportion of subjects with higher semen volume decreased with increased years of alcohol drinking (OR=0.962). Organophosphorous pesticide exposure decreased the number of forward progression sperm (OR=0.528), the sperm density (OR=0.266), the sperm viability (OR=0.398) and the percentage of normal morphology sperm (OR=0.281). A possible relationship was present between the season of semen collection and the number of forward progression sperm, sperm viability and percentage of normal morphology sperm. Compared with the summer data, the above three indices were higher in winter (OR being 2. 272, 4.060 and 5.249, respectively). Conclusion: Exposure to organophosphorous pesticide could damage the semen quality of the peasants. Education and alcohol drinking also affect the semen quality.展开更多

Reports show continued patient satisfaction after surgery despite not maintaining clinical improvement as measured by evolution scales. Objectives: The present study sought to explore expectations and level of satisfaction in patients after DBS surgery with a semi-structured questionnaire and subsequent correlation with functional scales, Quality of Life (QoL), and motor and non-motor symptoms. Methods: We performed descriptive statistics to represent demographic data, Wilcoxon rank tests to determine significant differences, and Spearman correlation between the applied scales. Results: We evaluated 20 patients with a history of DBS surgery. 45% were female, with a mean age of 55.7 ± 14.15 years, a mean disease duration of 13.42 ± 8.3 years, and a mean time after surgery of 3.18 ± 1.86 years. Patients reported surgery meeting expectations in 85.5% and continued satisfaction in 92%. These two variables showed a significant correlation. Conclusions: This sample of patients remained satisfied after DBS surgery, although we found no differences in motor and non-motor clinimetric scales. Further studies are needed to confirm the importance of assessing quality of life in patients with DBS.展开更多
