RESUMEN
In 2012, a controversial study on the long-term toxicity of a Roundup herbicide and the glyphosate-tolerant genetically modified (GM) maize NK603 was published. The EC-funded G-TwYST research consortium tested the potential subchronic and chronic toxicity as well as the carcinogenicity of the glyphosate-resistant genetically modified maize NK603 by performing two 90-day feeding trials, one with GM maize inclusion rates of 11 and 33% and one with inclusion rates of up to 50%, as well as a 2-year feeding trial with inclusion rates of 11 and 33% in male and female Wistar Han RCC rats by taking into account OECD Guidelines for the testing of chemicals and EFSA recommendations on the safety testing of whole-food/feed in laboratory animals. In all three trials, the NK603 maize, untreated and treated once with Roundup during its cultivation, and the conventional counterpart were tested. Differences between each test group and the control group were evaluated. Equivalence was assessed by comparing the observed difference to differences between non-GM reference groups in previous studies. In case of significant differences, whether the effects were dose-related and/or accompanied by changes in related parameters including histopathological findings was evaluated. It is concluded that no adverse effects related to the feeding of the NK603 maize cultivated with or without Roundup for up to 2 years were observed. Based on the outcome of the subchronic and combined chronic toxicity/carcinogenicity studies, recommendations on the scientific justification and added value of long-term feeding trials in the GM plant risk assessment process are presented.

Domestic violence (DV) is experienced by 1 in 4 women in the United Kingdom during their lifetime, and most survivors will seek informal support from the people around them, even if they choose not to access help from professionals. Support from these relatives, friends, neighbors, and colleagues can provide a buffer against effects on the survivor's physical health, mental health, and quality of life, and has been shown to be protective against future abuse. There has been an absence of research studying members of survivors' networks and, in particular, investigating how the impact of DV might diffuse to affect them. A systematic literature review of reported research (either in peer-reviewed journals or in gray literature) was undertaken to explore the impacts of DV on survivor networks. Of the articles found, 24 had data relating to the topic area, though no study addressed the question directly. Framework analysis and meta-ethnography generated the following themes: physical health impacts, negative impacts on psychological well-being, direct impacts from the perpetrator, and beneficial impacts on psychological well-being. The studies in this review indicated that informal supporters may be experiencing substantial impact, including vicarious trauma and the risk of physical harm. Currently, there is little support available which is directly aimed at informal supporters of DV survivors, thus these findings have practical and policy implications, in order to acknowledge and meet their needs.
