Gendering the border effect: the double impact of Colombian insecurity and the Venezuelan refugee crisis

Abstract

In the Colombian–Venezuelan borderlands, the reconfiguration of armed group presence and mass migration create and reinforce conditions of high violence and risk. Against this backdrop, we ask: What are the gendered security implications of the double crisis in the borderlands? Based on fieldwork in four regions along the border, this article argues that the border effect is gendered; the very factors that coalesce to produce this effect exacerbate existing gendered power dynamics, particularly as these relate to gender-based violence. Accordingly, this article demonstrates the specific ways in which the border – as a facilitator, deterrent, magnet and/or disguise – reinforces experiences of gendered insecurity in this region. The article finishes by outlining the implications for other international borderland settings.     

Ethyl sulphate and ethyl glucuronide in vitreous humor as postmortem evidence marker for ethanol consumption prior to death

To clarify the circumstances of death, the degree of inebriation is of importance in many cases, but for several reasons the determination of the ethanol concentration in post-mortem samples can be challenging and the synopsis of ethanol and the direct consumption markers ethyl glucuronide (EtG) and ethyl sulphate (EtS) has proved to be useful. The use of a rather stable matrix like vitreous humor offers further advantages. The aim of this study was to determine the concentrations of ethanol and the biomarkers in the robust matrix of vitreous humor and to compare them with the respective levels in peripheral venous blood and urine. Samples of urine, blood from the femoral vein and vitreous humor were taken from 26 deceased with suspected ethanol consumption prior to death and analyzed for ethanol, EtS and EtG. In the urine samples creatinine was also determined. The personal data, the circumstances of death, the post-mortem interval and the information about ethanol consumption prior to death were recorded. EtG and EtS analysis in urine was performed by LC-ESI-MS/MS, creatinine concentration was determined using the Jaffé reaction and ethanol was detected by HS-GC-FID and by an ADH-based method. In general, the highest concentrations of the analytes were found in urine and showed statistical significance. The mean concentrations of EtG were 62.8mg/L (EtG100 206.5mg/L) in urine, 4.3mg/L in blood and 2.1mg/L in vitreous humor. EtS was found in the following mean concentrations: 54.6mg/L in urine (EtS100 123.1mg/L), 1.8mg/L in blood and 0.9mg/L in vitreous humor. Ethanol was detected in more vitreous humor samples (mean concentration 2.0g/kg) than in blood and urine (mean concentration 1.6g/kg and 2.1g/kg respectively). There was no correlation between the ethanol and the marker concentrations and no statistical conclusions could be drawn between the markers and matrices.     

A case of extreme agitation and death after the use of mephedrone in The Netherlands

A 36-year old man, having injured himself severely by smashing windows in a rage of fury, was arrested by the police. He died despite resuscitation attempts. The forensic autopsy showed many superficial skin lacerations, bruises and minor brain swelling, but there was no definitive cause of death. Toxicological analysis showed a high concentration of mephedrone in femoral blood (5.1mg/L) and traces of cocaine, MDMA and oxazepam. The remaining dose of mephedrone in the stomach contents was estimated at 113 mg. Tablets that were found in the house of the deceased also contained mephedrone. We attribute this man's death to a fatal oral intake of mephedrone, which probably led to a state of excited delirium. This was aggravated by blood loss from multiple wounds.     

A fatal intoxication by chloroprene

Objective Chloroprene, 2-chloro-1,3 butadiene, is a volatile synthetic liquid. The chloroprene monomer is extremely reactive and is used for the production of latexes and synthetic rubber such as Neoprene. Up to now an acute lethal human exposure has been described only once in the literature [19]. The intoxication is associated with nervous system depression, pulmonary edema, narcosis, and respiratory arrest. Case report A 29-year-old chemistry company worker was found unconscious in an empty vessel (depth: 3m) used for chloroprene. The man was dressed in shoes, trousers, a helmet and a respiratory mask. The upper part of the body was unclothed. In spite of reanimation, the man died three hours later in a hospital. Material and methods: All analyses were performed by headspace gas chromatography (HS/GC/FID). In addition, brain, muscle and myocardial muscle were analysed by headspace GC-MS. Results and discussion Autopsy findings: The cause of death could not be determined as the macromorphological findings were unspecific. Toxicology findings The calibration curve of chloroprene in serum shows linearity from 1.0 to 200 μg/ml (r(2)=0.9999) using benzene as internal standard. The LOD is 0.28 μg/ml, the LLOQ is 0.99 μg/ml. Tissues and body fluids were stored at -20 °C till the analysis. Chloroprene was quantified after addition of benzene as the internal standard. It was found in nearly all tissues and body fluids except in the urine and lung. The highest concentrations were detected in the kidney, liver, myocardial muscle and especially in the brain. Furthermore, hexanal was found in all samples except in the urine. The amount of hexanal in some specimens is high, especially in the lung, bile, gastric content and myocardial muscle. Conclusion We assume that a significant amount of chloroprene was not only inhaled but also absorbed through the skin because the man wore a respiratory mask. Presumably the accident would not have happened if the works safety protocols had been followed. The reason why high concentrations of hexanal were found in the tissues could not be clarified.     

The 2008 Declaration of Helsinki — First among Equals in Research Ethics?

The World Medical Association's (WMA) Declaration of Helsinki is one of the most important and influential international research ethics documents. Its most recent 2008 version declares unprecedented universal primacy over all existing national or international ethical, legal, or regulatory requirements. This self-proclaimed status as a set of minimal ethical standards raises important questions about the Declaration's appropriate normative status. The present paper argues that the new claim of ethical primacy is problematic and makes the Declaration unnecessarily vulnerable to criticism. Future revisions of the Declaration should therefore remove this claim and strengthen the document, first, by clarifying its normative status as a set of strong default recommendations, to be followed unless there is compelling ethical reason to do otherwise; and second, by improving the substance of the Declaration through further precision, specification, and argument.
