Assessment of potential cardiotoxic side effects of mitoxantrone in patients with multiple sclerosis

Previous studies showed that mitoxantrone can reduce disability progression in patients with multiple sclerosis (MS). There is, however, concern that it may cause irreversible cardiomyopathy with reduced left ventricular (LV) ejection fraction (EF) and congestive heart failure. The aim of this prospective study was to investigate cardiac side effects of mitoxantrone by repetitive cardiac monitoring in MS patients. The treatment protocol called for ten courses of a combined mitoxantrone (10 mg/m(2) body surface) and methylprednisolone therapy. Before each course, a transthoracic echocardiogram was performed to determine the LV end-diastolic diameter, the end-systolic diameter and the fractional shortening; the LV-EF was calculated. Seventy-three patients participated (32 males; age 48 +/- 12 years, range 20-75 years; 25 with primary progressive, 47 with secondary progressive and 1 with relapsing-remitting MS) who received at least four courses of mitoxantrone. Three of the 73 patients were excluded during the study (2 patients discontinued therapy; 1 patient with a previous history of ischemic heart disease developed atrial fibrillation after the second course of mitoxantrone). The mean cumulative dose of mitoxantrone was 114.0 +/- 33.8 mg. The mean follow-up time was 23.4 months (range 10-57 months). So far, there has been no significant change in any of the determined parameters (end-diastolic diameter, end-systolic diameter, fractional shortening, EF) over time during all follow-up investigations. Mitoxantrone did not cause signs of congestive heart failure in any of the patients. Further cardiac monitoring is, however, needed to determine the safety of mitoxantrone after longer follow-up times and at higher cumulative doses. Copyright (C) 2005 S. Karger AG, Basel

'Word from the street' : when non-electoral representative claims meet electoral representation in the United Kingdom

Taking the specific case of street protests in the UK – the ‘word from the street’– this article examines recent (re)conceptualizations of political representation, most particularly Saward’s notion of ‘representative claim’. The specific example of nonelectoral claims articulated by protestors and demonstrators in the UK is used to illustrate: the processes of making, constituting, evaluating and accepting claims for and by constituencies and audiences; and the continuing distinctiveness of claims based upon electoral representation. Two basic questions structure the analysis: first, why would the political representative claims of elected representatives trump the nonelectoral claims of mass demonstrators and, second, in what ways does the ‘perceived legitimacy’ of the former differ from the latter

Storytelling as 'unorthodox' agency:negotiating the 2012 family immigration rules (United Kingdom)

This article attends to the lived experience of binational families subject to the 2012 family immigration rules (FIR). It seeks to enrich the pre-existing discussions of family migration within the European Union (EU) and the United Kingdom, focusing on the ‘micro-political’ experiences of those whose lives have been adversely affected by their introduction. It draws on the life writings of binational families, suggesting that a micro-political focus reveals an ongoing neuropolitical experience that traditional accounts of moral agency are ill-equipped to negotiate. The article suggests an unorthodox interpretation of agency premised on storytelling, while probing the tensions that emerge when this lived experience is framed in such a manner. It concludes by positing a series of questions relating to the value of a neuropolitical labelling of the subject and suggests a need to further engage with traumatic interpretations of harm at the intersection of citizenship rights and mobility rights

Filial obligations to elderly parents: a duty to care?

A continuing need for care for elderly, combined with looser family structures prompt the question what filial obligations are. Do adult children of elderly have a duty to care? Several theories of filial obligation are reviewed. The reciprocity argument is not sensitive to the parent–child relationship after childhood. A theory of friendship does not offer a correct parallel for the relationship between adult child and elderly parent. Arguments based on need or vulnerability run the risk of being unjust to those on whom a needs-based claim is laid. To compare filial obligations with promises makes too much of parents’ expectations, however reasonable they may be. The good of being in an unchosen relationship seems the best basis for filial obligations, with an according duty to maintain the relationship when possible. We suggest this relationship should be maintained even if one of the parties is no longer capable of consciously contributing to it. We argue that this entails a duty to care about one’s parents, not for one’s parents. This implies that care for the elderly is not in the first place a task for adult children

Responsibility Ascriptions in Technology Development and Engineering: Three Perspectives

In the last decades increasing attention is paid to the topic of responsibility in technology development and engineering. The discussion of this topic is often guided by questions related to liability and blameworthiness. Recent discussions in engineering ethics call for a reconsideration of the traditional quest for responsibility. Rather than on alleged wrongdoing and blaming, the focus should shift to more socially responsible engineering, some authors argue. The present paper aims at exploring the different approaches to responsibility in order to see which one is most appropriate to apply to engineering and technology development. Using the example of the development of a new sewage water treatment technology, the paper shows how different approaches for ascribing responsibilities have different implications for engineering practice in general, and R&D or technological design in particular. It was found that there was a tension between the demands that follow from these different approaches, most notably between efficacy and fairness. Although the consequentialist approach with its efficacy criterion turned out to be most powerful, it was also shown that the fairness of responsibility ascriptions should somehow be taken into account. It is proposed to look for alternative, more procedural ways to approach the fairness of responsibility ascriptions

Alternatives to project-specific consent for access to personal information for health research: Insights from a public dialogue

<p>Abstract</p> <p>Background</p> <p>The role of consent for research use of health information is contentious. Most discussion has focused on when project-specific consent may be waived but, recently, a broader range of consent options has been entertained, including broad opt-in for multiple studies with restrictions and notification with opt-out. We sought to elicit public values in this matter and to work toward an agreement about a common approach to consent for use of personal information for health research through deliberative public dialogues.</p> <p>Methods</p> <p>We conducted seven day-long public dialogues, involving 98 participants across Canada. Immediately before and after each dialogue, participants completed a fixed-response questionnaire rating individuals' support for 3 approaches to consent in the abstract and their consent choices for 5 health research scenarios using personal information. They also rated how confident different safeguards made them feel that their information was being used responsibly.</p> <p>Results</p> <p>Broad opt-in consent for use of personal information garnered the greatest support in the abstract. When presented with specific research scenarios, no one approach to consent predominated. When profit was introduced into the scenarios, consent choices shifted toward greater control over use. Despite lively and constructive dialogues, and considerable shifting in opinion at the individual level, at the end of the day, there was no substantive aggregate movement in opinion. Personal controls were among the most commonly cited approaches to improving people's confidence in the responsible use of their information for research.</p> <p>Conclusion</p> <p>Because no one approach to consent satisfied even a simple majority of dialogue participants and the importance placed on personal controls, a mechanism should be developed for documenting consent choice for different types of research, including ways for individuals to check who has accessed their medical record for purposes other than clinical care. This could be done, for example, through a web-based patient portal to their electronic health record. Researchers and policy makers should continue to engage the public to promote greater public understanding of the research process and to look for feasible alternatives to existing approaches to project-specific consent for observational research.</p

Framing Social Justice: The Ties That Bind a Multinational Occupational Community

The notion of a frame is central to the conceptualisation of social justice and the grounding of social justice claims. Influential theories of social justice are typically grounded in national or cosmopolitan framings. Those entitled to raise claims of injustice are identified as citizens of states or the globe, respectively. The re-visioning of understandings of space and belonging, incumbent in the processes of globalisation, problematises static geographical framings. We offer an alternative lens and argue for the inclusion of sociological data in accounts of social justice to identify the relevant framing of the community of entitlement. Drawing on secondary analysis of a qualitative dataset, we explore the case of multinational seafarers caught at the intersection of competing appeals to nationality and commonality as an exemplar of transnational workers. And, argue that there are compelling grounds to treat this group of multinational seafarers as a community of entitlement
