https://www.selleckchem.com/ Residual patent ductus arteriosus was seen in 6 cases from group 1 (5.4%) and 12 patients from group 2 (5.7%). None of the cases in group 1 had vascular complications, while vascular complications were seen in 20 cases, all of them in group 2 (9.5%). Nonvascular complications were seen in one patient from group 1 (0.9%) and 15 patients in group 2 (7.1%). The procedure time and fluoroscopy times were less in patients with exclusive transvenous access.

The aim of this study was to find the cross-sectional association between oral contraceptive use and Helicobacter pylori seroprevalence. Data were obtained from the US National Health and Nutrition Examination Survey (NHANES). The H. pylori immunoglobulin G (IgG) enzyme-linked immunosorbent assays were used to categorise participants as seropositive or seronegative. The study population included 799 female participants who had information on H. pylori seroprevalence and all other covariates and had not been taking any medications (except oral contraceptives). The bivariate Rao-Scott chi-square test indicated a significant association between H. pylori seroprevalence and contraceptive use (P less then 0.01). The variables of race, education, poverty income ratio, smoking, and blood lead and cadmium levels were also significantly associated with H. pylori seroprevalence (P less then 0.01). Multiple logistic regression analysis of the age-adjusted model revealed that contraceptive users are 65% less likely of being H. pylori seropositive as compared to non-contraceptive users (odds ratio (OR) 0.35, 95% confidence interval (CI) 0.18-0.68). This association is stronger with the final multivariate model
