Treatment of inferior vena cava obstruction in hemodialysis patients using Wallstents: Early and intermediate results

OBJECTIVE. The purpose of this study was to evaluate the efficacy of Wallstents in treating inferior vena cava obstruction in hemodialysis patients. CONCLUSION. For the short and intermediate term, percutaneous placement of inferior vena cava Wallstents, followed by balloon angioplasty, is a safe and valuable technique for preserving the often limited central venous access in hemodialysis patients. To maintain patency, recurrent stenosis within the Wallstent can be treated with additional angioplasty.link_to_subscribed_fulltex

Male Perpetration of Teen Dating Violence: Associations with Neighborhood Violence Involvement, Gender Attitudes, and Perceived Peer and Neighborhood Norms

This study aims to examine the link between male perpetration of teen dating violence (TDV) and neighborhood violence, as well as associations with gender attitudes and perceived peer and neighborhood norms related to violence among a sample of urban adolescent boys. Participants of this cross-sectional study (N = 275) were between the ages of 14 and 20 years and recruited from urban community health centers. Crude and adjusted logistic and linear regression models were used to examine TDV perpetration in relation to (a) neighborhood violence involvement, (b) perceptions of peer violence, (c) perceptions of neighborhood violence, and (d) gender attitudes. Slightly more than one in four (28%) boys reported at least one form of TDV perpetration; among boys who have ever had sex, almost half (45%) reported at least one form of TDV perpetration. In logistic and linear regression models adjusted for demographics, boys who reported TDV perpetration were more likely to report involvement in neighborhood violence (odds ratio (OR) = 3.1; 95% confidence interval (CI) = 1.7–5.5), beliefs that their friends have perpetrated TDV (OR = 2.7; 95%CI = 1.4–5.1), perceptions of violent activity within their neighborhood (OR = 3.0; 95%CI = 1.4–6.3), and greater support of traditional gender norms (β = 3.2, p = 0.002). The findings suggest that efforts are needed to address boys’ behaviors related to the perpetration of multiple forms of violence and require explicit efforts to reduce perceived norms of violence perpetration as well as problematic gender attitudes (e.g., increasing support for gender equity) across boys’ life contexts
