End-of-life healthcare decisions, ethics and law: the debate in Spain

The debate on euthanasia in Spain has been ongoing from the beginning of the 20th century and remains extant. Three periods can be identified: prior to 1978, 1978-2002, and after 2002. The debate increased significantly after the Ramon Sampedro case (1995-1998), and was fuelled with new, although very different cases, such as those of Leganés (2005-2008), Jorge Leon (2006) or Inmaculada Echevarria (2006-2007). As a consequence of these cases in 2008 the Regional Government of Andalusia started a legal process to pass a law regulating end-of-life decisions, excluding euthanasia and assisted-suicide, which was finally enacted in 2010. Two other Spanish regions (Navarra and Aragón) passed similar laws. The central government also initiated a legal process to approve a national law, excluding euthanasia and assisted-suicide. The project failed because of the dissolution of the Parliament in June 2011. The new government will have to decide how to continue the process.     

Chemistry in crime investigation: sodium percarbonate effects on bloodstains detection

Chemistry plays a leading role in crime investigation. In the study of bloodstains, chemical reactions provide the means for the detection. All these procedures have been thoroughly studied. However, recently, a new source of error has been found: washing stains with "active oxygen" detergents abrogates presumptive and human hemoglobin tests for bloodstains (although visible). The aim of this investigation was to evaluate the ability of pure sodium percarbonate-main component of detergents-to abrogate presumptive and human hemoglobin tests. Then, a solution to this problem could be found. The results demonstrate that pure sodium percarbonate-itself-is able to abrogate all tests, as well as the different degrees to which each of them is affected by the product. Consequently, faced with a stain of bloody appearance, even the preliminary tests are negative; it is advisable to analyze the DNA. Otherwise, the opportunity of obtaining valuable information is lost.     

Nuclear DNA typing from ancient teeth

Because of the adverse effects that diagenesis exert on ancient skeletal remains, DNA from these samples is often compromised to the point where genetic typing can be challenging. Nevertheless, robust and reliable methods are currently available to allow successful genotyping of ancient specimens. Here we report nuclear DNA-based methods and typing strategies used to analyze 2 human skeletons from a medieval burial. Reliable DNA nuclear profiles were obtained from teeth, whereas mitochondrial DNA analyses in bones were inconclusive. A complete nuclear mini short tandem repeat profile was obtained from a well-preserved premolar, but only a partial one from the femur. Increasing the sensitivity of the polymerase chain reaction system allowed a full profile from the latter, but the presence of artifacts reinforced the idea that the interpretation of this kind of analysis must be performed with caution. The results presented here also indicate that DNA from dental pieces can be better preserved than from bones, even in the case of well-preserved long bones with thick cortical tissue such as the femurs, and have a better chance of successful genetic typing, probably because of the high degree of protection conferred to the DNA by the enamel.     

Violent behaviors in drug addiction: differential profiles of drug-addicted patients with and without violence problems

This study explored the prevalence of violent behaviors in patients who are addicted to drugs. A sample of 252 addicted patients (203 male and 49 female) who sought outpatient treatment was assessed. Information on violent behaviors, sociodemographic factors, consumption factors (assessed by the European version of the Addiction Severity Index [EuropASI]), psychopathological factors (assessed by Symptom Checklist-90-Revised [SCL-90-R]), and personality variables (assessed by Millon Clinical Multiaxial Inventory [MCMI-II]) was collected. Drug-addicted patients who were associated with violent behaviors were compared on all variables with patients who were not associated with violent behaviors. The rate of drug-addicted patients with violent behaviors in this sample was 39.68% (n = 100). There were significant differences between the numbers of patients who did and did not demonstrate violence on some variables. Patients with violence problems were younger than those without violence problems and were more likely to report having been a victim of abuse. Moreover, they were significantly more likely to have experienced an overdose and showed a significantly higher score on several EuropASI, SCL-90-R and MCMI-II variables. According to these results, patients with violence control problems present with both a more severe addiction and several comorbid problems. The implications of these results for further research and clinical practice are discussed.     

Introduction: citizenship as inhabitance? Migrant housing squats versus institutional accommodation

ABSTRACT

This special issue focuses on migrants’ self-organised strategies in relation to housing in Europe, namely the collective squatting of vacant buildings and land. In particular, the contributions to this special issue differentiate between shelter provided in state-run or humanitarian camps and squatted homes. Migrants squats are an essential part of the ‘corridors of solidarity’ that are being created throughout Europe, where grassroots social movements engaged in anti-racist, anarchist and anti-authoritarian politics coalesce with migrants in devising non-institutional responses to the violence of border regimes. In these spaces contentious politics and everyday social reproduction uproot racist and xenophobic regimes. The struggles emerging in these spaces disrupt host-guest relations, which often perpetuate state-imposed hierarchies and humanitarian disciplining technologies. Moreover, the solidarities and collaborations between undocumented and documented activists challenge hitherto prevailing notions of citizenship and social movements, as well as current articulations of the common. These radical spaces enable possibilities for inhabitance beyond, against and within citizenship, which do not only reverse forms of exclusion and repression, but produce ungovernable resources, alliances and subjectivities that prefigure more livable spaces for all. Therefore, these struggles are interpreted here as forms of commoning, as they constitute autonomous socio-political infrastructures and networks of solidarity beyond and against the state and humanitarian provision
