We argue that the dead donor rule, which states that multiple vital organs should only be taken from dead patients, is justified neither in principle nor in practice. We use a thought experiment and a guiding assumption in the literature about the justification of moral principles to undermine the theoretical justification for the rule. We then offer two real world analogues to this thought experiment, voluntary active euthanasia and capital punishment, and argue that the moral permissibility of terminating any patient through the removal of vital organs cannot turn on whether or not the practice violates the dead donor rule. Next, we consider practical justifications for the dead donor rule. Specifically, we consider whether there are compelling reasons to promulgate the rule even though its corresponding moral principle is not theoretically justified. We argue that there are no such reasons. In fact, we argue that promulgating the rule may actually decrease public trust in organ procurement procedures and medical institutions generally - even in states that do not permit capital punishment or voluntary active euthanasia. Finally, we examine our case against the dead donor rule in the light of common arguments for it. We find that these arguments are often misplaced - they do not support the dead donor rule. Instead, they support the quite different rule that patients should not be killed for their vital organs.

Our goal in this article is to explicate the way, and the extent to which, euthanasia can be voluntary from both the perspective of the patient and the perspective of the health care providers involved in the patient's care. More significantly, we aim to challenge the way in which those engaged in ongoing philosophical debates regarding the morality of euthanasia draw distinctions between voluntary, involuntary, and nonvoluntary euthanasia on the grounds that drawing the distinctions in the traditional manner (1) fails to reflect what is important from the patient's perspective and (2) fails to reflect the significance of health care providers' interests, including their autonomy and integrity.
It is often accepted that we may legitimately speak about voluntary euthanasia only in cases of persons who are suffering because they are incurably injured or have an incurable disease. This article argues that when we consider the moral acceptability of voluntary euthanasia, we have no good reason to concentrate only on persons who are ill or injured and suffering.

A comparison of the views of geriatric medicine physicians and intensive care physicians in the United Kingdom on the topics of active voluntary euthanasia and physician-assisted suicide revealed rather different attitudes. Eighty percent of geriatricians, but only 52% of intensive care physicians, considered active voluntary euthanasia as never justified ethically. Gender and age did not play a major part in attitudinal differences of the respondents. If the variability of attitudes of these two medical specialties are anywhere near illustrative of other physicians in the United Kingdom, it would be difficult to formulate and implement laws and policies concerning euthanasia and assisted suicide. In addition, ample safeguards would be required to receive support from physicians regarding legalization.

One of the most recent controversies to arise in the field of bioethics concerns the ethics for the Groningen Protocol: the guidelines proposed by the Groningen Academic Hospital in The Netherlands, which would permit doctors to actively euthanise terminally ill infants who are suffering. The Groningen Protocol has been met with an intense amount of criticism, some even calling it a relapse into a Hitleresque style of eugenics, where people with disabilities are killed solely because of their handicaps. The purpose of this paper is threefold. First, the paper will attempt to disabuse readers of this erroneous understanding of the Groningen Protocol by showing how such a policy does not aim at making quality‐of‐life judgements, given that it restricts euthanasia to suffering and terminally ill infants. Second, the paper illustrates that what the Groningen Protocol proposes to do is both ethical and also the most humane alternative for these suffering and dying infants. Lastly, responses are given to some of the worries expressed by ethicists on the practice of any type of non‐voluntary active euthanasia. PMID:17074822

The objective of the study was to gain insight into the knowledge of and attitudes towards voluntary active euthanasia and doctor-assisted suicide (EEDAS) of Dutch medical students, and to determine whether knowledge and attitudes change after a 1-day informative conference about EDAS. Data were collected by means of two self-administered questionnaires. Questionnaire 1 had to be completed before the start of the conference and questionnaire 2 after the conference. In both questionnaires, students were asked by means of two open-ended questions to define euthanasia and doctor-assisted suicide. They were also asked to indicate which of eight statements met with the requirements for prudent practice. Finally, the students were asked to what extent they agreed or disagreed with each of seven statements about attitudes towards EDAS. To determine if a selection occurred among students who returned both questionnaires, their background characteristics, and knowledge and attitudes towards EDAS were compared with those who returned only the first questionnaire. Forty-seven students returned only the first questionnaire, while both questionnaires were returned by 137 students. No differences were found between students who returned both questionnaires and those who returned only the first questionnaire with regard to age, religion, knowledge of and attitudes towards EDAS. Students' knowledge of the definitions of EDAS and the requirements for prudent practice improved significantly. Students' reactions to the statements on attitudes towards EDAS showed that a large majority had a fairly positive attitude towards EDAS. There was no significant difference before and after the conference. Male students and students with a religion were more opposed to EDAS than female students and students without a religion. The fact that the students' knowledge of EDAS improved after a 1-day conference does not imply sufficient understanding of the issue. Because EDAS is allowed only under

This paper outlines the relationship between euthanasia and its ethical norms and practices in a part of West Africa. The various sub-types of euthanasia are described in detail, parallel with the role of African ethical theories in determining their relevance. The author discusses the implications of this approach relative to the social and economic state of African communities.

The Groningen Protocol allows active euthanasia of severely ill newborns with unbearable suffering. Defenders of the protocol insist that the protocol refers to terminally ill infants and that quality of life should not be a factor in the decision to euthanize an infant. They also argue that there should be no ethical difference between active and passive euthanasia of these infants. However, nowhere in the protocol does it refer to terminally ill infants; on the contrary, the developers of the protocol take into account the future quality of life of the infant. We also note how the Nazi Euthanasie Programm started with the premise that there is some life not worthy of living. Therefore, in our opinion, the protocol violates the traditional ethical codes of physicians and the moral values of the overwhelming majority of the citizens of the world.

This article invites consideration of how Australia should regulate voluntary euthanasia and assisted suicide. It attempts to pose this question as neutrally as possible, acknowledging that both prohibition and legalisation of such conduct involve decisions about regulation. It begins by charting the wider field of law at the end of life, before considering the repeated, but ultimately unsuccessful, attempts at law reform in Australia. The situation in Australia is contrasted with permissive jurisdictions overseas where voluntary euthanasia and/or assisted suicide are lawful. The authors consider the arguments for and against legalisation of such conduct along with the available empirical evidence as to what happens in practice both in Australia and overseas. The article concludes by outlining a framework for deliberating on how Australia should regulate voluntary euthanasia and assisted suicide. It asks a threshold question of whether such conduct should be criminal acts (as they presently are), the answer to which then leads to a range of possible regulatory options.
The distinction between 'kill' and 'help to die' is argued by analogy with the distinction between 'rape' and 'make love to'. The difference is the consent of the receiver of the act, therefore 'kill' is the wrong word for an act of active voluntary euthanasia. The argument that doctors must not be allowed by law to perform active voluntary euthanasia because this would recognise an infringement of the sanctity of life ('the red light principle') is countered by comparing such doctors with the drivers of emergency vehicles, who are allowed to drive through red lights.

The problem of euthanasia emerges again and again in today's Europe. The Dutch type of regulation of euthanasia could be introduced into the Hungarian legal system. Today, in Hungary, the ethical guidelines of the chamber of medicine, the criminal law and the administrative health law also forbid active euthanasia. In Hungary, the criminal code reform of 2012 missed to liberalise the regulation of euthanasia. Such liberalisation awaits bottom-up support from the part of the society. In Europe, active euthanasia is legal only in the Netherlands, Belgium, Luxemburg and Switzerland. In Hungary, a passive form of euthanasia is legal, i.e. a dying patient may, under strict procedural circumstances, refuse medical treatment. The patient is not allowed to refuse medical treatment, if she is pregnant and foreseeably capable to give birth to her child.

A study on the attitudes of adults related to the voluntary termination of life showed that those persons with favorable attitudes toward suicide were also favorable toward euthanasia. Religiosity was negatively associated with pro-euthanasia attitudes. Whites and males were more favorable toward euthanasia than Blacks and females. (Author)
Clinical practice may pose an ethical dilemma: is it better to actively kill a patient or let her/him die naturally and more slowly? The former may be considered to involve less suffering than a slow death possibly full of suffering. The central problem in respect of euthanasia is how to define, which level of suffering is intolerable. In practice, persons suffering particularly from degenerative and chronic neurological diseases experience helplessness and powerlessness as a burden. The scope of suffering is changing over time, whereby the establishment of permanent guidelines for euthanasia is difficult.
Background While a number of reviews have explored the attitude of health professionals toward euthanasia, none of them documented their motivations to practice euthanasia. The objective of the present systematic review was to identify physicians’ and nurses’ motives for having the intention or for performing an act of voluntary euthanasia and compare findings from countries where the practice is legalized to those where it is not. Methods The following databases were investigated: MEDLINE/PubMed (1950+), PsycINFO (1806+), CINAHL (1982+), EMBASE (1974+) and FRANCIS (1984+). Proquest Dissertations and Theses (1861+) was also investigated for gray literature. Additional studies were included by checking the references of the articles included in the systematic review as well as by looking at our personal collection of articles on euthanasia. Results This paper reviews a total of 27 empirical quantitative studies out of the 1 703 articles identified at the beginning. Five studies were in countries where euthanasia is legal and 22 in countries where it is not. Seventeen studies were targeting physicians, 9 targeted nurses and 1 both health professionals. Six studies identified the motivations underlying the intention to practice euthanasia, 16 the behavior itself and 5 both intention and behavior. The category of variables most consistently associated with euthanasia is psychological variables. All categories collapsed, the four variables most frequently associated with euthanasia are past behavior, medical specialty, whether the patient is depressed and the patient’s life expectancy. Conclusions The present review suggests that physicians and nurses are motivated to practice voluntary euthanasia especially when they are familiar with the act of euthanasia, when the patient does not have depressive symptoms and has a short life expectancy and their motivation varies according to their medical specialty. Additional studies among nurses and in countries where
When medical treatment becomes futile, or the patient's suffering is intractable, doctors face the agonising dilemma of whether to proceed with euthanasia. It is important for a doctor to be familiar with the law surrounding euthanasia, in order to avoid prosecution. This paper explores the law in England and Wales regarding the different categories of euthanasia: voluntary euthanasia, nonvoluntary euthanasia, passive euthanasia, and active euthanasia.

John Keown has constructed a logical slippery slope argument from voluntary euthanasia (VAE) to nonvoluntary euthanasia (NVAE). VAE if justified implies that death can be of overall benefit, in which case it should also be facilitated in those who cannot consent (NVAE). Hallvard Lillehammer asserts that Keown's argument rests on a fallacy. However, pace Lillehammer, it can be restated to escape this fallacy. Its validity is confirmed by applying to VAE some well-established general principles of medical decision making. Thus, either VAE and NVAE must be accepted together or, if NVAE is regarded as unacceptable, VAE should also be rejected.

This study investigated the level of support for voluntary and nonvoluntary euthanasia under three conditions of suffering (pain; debilitated nature of the body; burden on the family) experienced by oneself, a significant other, and a person in general. The sample consisted of 1,897 Thai adults (719 males, 1,178 females) who voluntarily filled in the study's questionnaire. Initial multivariate analysis of variance indicated significant group (oneself, significant other, person in general) differences in level of support for voluntary and nonvoluntary euthanasia and under the three conditions of suffering. Multigroup path analysis conducted on the posited euthanasia model showed that the three conditions of suffering exerted differential direct and indirect influences on the support of voluntary and nonvoluntary euthanasia as a function of the identity of the person for whom euthanasia was being considered. The implications of these findings are discussed.

Assisted death and voluntary euthanasia have received significant and sustained media attention in recent years. High-profile cases of people seeking assistance to end their lives have raised, at least in the popular press, debate about whether individuals should be able to seek such assistance at a time when they consider their suffering to be unbearable or their quality of life unsatisfactory. Other recent developments include a number of attempts to legislate on the issue by the minor parties in Australia and the successful enactment of legislation in a few overseas jurisdictions. However, despite all of the recent attention that has focused on assisted death and voluntary euthanasia, a discussion of the adequacy of existing laws has not made it onto the political agenda of any of the Australian State or Territory governments. This is in spite of the fact that the private views of the majority of our elected Members of Parliament may be supportive of reform. This article explores the role of politicians' views and, as a case study, considers the opinions expressed by a number of Queensland Members of Parliament. In light of the views of these politicians and those of members of the public, as well as considerations arising from current medical practice, the article argues that there is a need for open political debate on assisted death and voluntary euthanasia. The article also suggests ways that such a debate may be achieved while minimising any political impact on governments that are prepared at least to consider this issue.

Euthanasia is one of the controversial topics in current medical ethics. Among the six well-known types of euthanasia, passive voluntary euthanasia (PVE) seems to be more plausible in comparison with other types, from the moral point of view. According to the Kantian framework, ethical features come from ‘reason’. Maxims are formulated as categorical imperative which has three different versions. Moreover, the second version of categorical imperative which is dubbed ‘principle of ends’ is associated with human dignity. It follows from this that human dignity has an indisputable role in the Kantian story. On the other hand, there are two main theological schools in Islamic tradition which are called: Ash’arite and Mu’tazilite. Moreover, there are two main Islamic branches: Shiite and Sunni. From the theological point of view, Shiite’s theoretical framework is similar to the Mu’tazilite one. According to Shiite and Mu’tazilite perspectives, moral goodness and badness can be discovered by reason, on its own. Accordingly, bioethical judgments can be made based on the very concept of human dignity rather than merely resorting to the Holy Scripture or religious jurisprudential deliberations. As far as PVE is concerned, the majority of Shiite scholars do not recognize a person’s right to die voluntarily. Similarly, on the basis of Kantian ethical themes, PVE is immoral, categorically speaking. According to Shiite framework, however, PVE could be moral in some ethical contexts. In other words, in such contexts, the way in which Shiite scholars deal with PVE is more similar to Rossian ethics rather than the Kantian one. PMID:23908735
Some writers have argued that a Kantian approach to ethics can be used to justify suicide in cases of extreme dementia, where a patient lacks the rationality required of Kantian moral agents. I worry that this line of thinking may lead to the more extreme claim that euthanasia is a proper Kantian response to severe dementia (and similar afflictions). Such morally treacherous thinking seems to be directly implied by the arguments that lead Dennis Cooley and similar writers to claim that Kant might support suicide. If rationality is the only factor in valuing a human life, then the loss of that rationality (however such loss might be defined) would allow us to use essentially utilitarian thinking in order to support non-voluntary euthanasia, since the patients themselves would no longer be moral agents that demand respect.
The institution of active euthanasia has been legal in Colombia since 2015. In California, the regulation on physician-assisted suicide will come into effect on January 1, 2016. The legal institution of active euthanasia is not accepted under the law of the United States of America, however, physician-assisted suicide is accepted in an increasing number of member states. The related regulation in Oregon is imitated in other member states. In South America, Colombia is not the first country to legalize active euthanasia: active euthanasia has been legal in Uruguay since 1932. The North American legal tradition markedly differs from the South American one and both are incompatible with the Central European rule of law. In Hungary and in most European Union countries, solely the passive form of euthanasia is legal. In the Benelux countries, the active form of euthanasia is legal because the supranational law of the European Union does not prohibit it. Notwithstanding, European Union law does not prescribe legalization of either the active form of euthanasia, or the physician-assisted suicide.

The role of nurses in AIDS care regarding voluntary euthanasia and assisted suicide: a call for further dialogue Because of the nature of their work, nurses are directly involved with terminally ill patients and the problems associated with the decision to hasten death through voluntary euthanasia or assisted suicide (VE/AS). An anonymous survey delivered to nurses working in HIV/AIDS settings in Canada was used to analyse nurses' experiences and attitudes regarding VE/AS. An emergent analysis of 22 nurses' responses to an open-ended prompt appearing at the end of the survey reveals that nurses: support death-hastening practices; believe that legislation for these practices needs to be established; are wary of the potential abuse of VE/AS; and believe that further discussion on end-of-life issues is imperative. Their caring role in the health care setting places nurses in key positions to stimulate discussion in this area.

Objective—To demonstrate Japanese doctors' and nurses' attitudes towards and practices of voluntary euthanasia (VE) and to compare their attitudes and practices in this regard. Design—Postal survey, conducted between October and December 1999, using a self-administered questionnaire. Participants—All doctor members and nurse members of the Japanese Association of Palliative Medicine. Main outcome measure—Doctors' and nurses' attitude towards and practices of VE. Results—We received 366 completed questionnaires from 642 doctors surveyed (response rate, 58%) and 145 from 217 nurses surveyed (68%). A total of 54% (95% confidence interval (CI): 49-59) of the responding doctors and 53% (CI: 45-61) of the responding nurses had been asked by patients to hasten death, of whom 5% (CI: 2-8) of the former and none of the latter had taken active steps to bring about death. Although 88% (CI: 83-92) of the doctors and 85% (CI: 77-93) of the nurses answered that a patient's request to hasten death can sometimes be rational, only 33% (CI: 28-38) and 23% (CI: 16-30) respectively regarded VE as ethically right and 22% (CI: 18-36) and 15% (CI: 8-20) respectively would practise VE if it were legal. Logistic regression model analysis showed that the respondents' profession was not a statistically independent factor predicting his or her response to any question regarding attitudes towards VE. Conclusions—A minority of responding doctors and nurses thought VE was ethically or legally acceptable. There seems no significant difference in attitudes towards VE between the doctors and nurses. However, only doctors had practised VE. Key Words: Euthanasia • Japan • doctors • nurses • palliative care PMID:11579190

Ever since the start of the twentieth century, a growing interest and importance of studying fatwas can be noted, with a focus on Arabic printed fatwas (Wokoeck 2009). The scholarly study of end-of-life ethics in these fatwas is a very recent feature, taking a first start in the 1980s (Anees 1984; Rispler-Chaim 1993). Since the past two decades, we have witnessed the emergence of a multitude of English fatwas that can easily be consulted through the Internet ('e-fatwas'), providing Muslims worldwide with a form of Islamic normative guidance on a huge variety of topics. Although English online fatwas do provide guidance for Muslims and Muslim minorities worldwide on a myriad of topics including end-of-life issues, they have hardly been studied. This study analyses Islamic views on (non-)voluntary euthanasia and assisted suicide as expressed in English Sunni fatwas published on independent--i.e. not created by established organisations--Islamic websites. We use Tyan's definition of a fatwa to distinguish between fatwas and other types of texts offering Islamic guidance through the Internet. The study of e-fatwas is framed in the context of Bunt's typology of Cyber Islamic Environments (Bunt 2009) and in the framework of Roy's view on the virtual umma (Roy 2002). '(Non-)voluntary euthanasia and assisted suicide' are defined using Broeckaert's conceptual framework on treatment decisions at the end of life (Broeckaert 2008). We analysed 32 English Sunni e-fatwas. All of the e-fatwas discussed here firmly speak out against every form of active termination of life. They often bear the same structure, basing themselves solely on Quranic verses and prophetic traditions, leaving aside classical jurisprudential discussions on the subject. In this respect they share the characteristics central in Roy's typology of the fatwa in the virtual umma. On the level of content, they are in line with the international literature on Islamic end-of-life ethics. English Sunni e-fatwas make

Euthanasia is a controversial issue in today's society. In countries where euthanasia is legal, it is mainly associated with people with cancer. We retrospectively studied the frequency and basis of patients' requests for active euthanasia in the oncology setting.MethodsRecurrent requests for euthanasia made by the patients of Leon-Berard cancer center (Lyon, France) between 2001 and 2003 were recorded by questioning the physicians and nurse supervisors in charge or by collecting information from the minutes of multidisciplinary palliative care meetings. We also collected information on the general health status of the patients, their motives and their evolution over time, as well as responses from caregivers.ResultsWe identified 16 requests for euthanasia. These involved 8 men, 7 women and 1 child (median age, 56 years), corresponding to 1% of the total deaths recorded during the period. In 2 cases, the request had come from the family only. The most frequent motives were psychological distress (38%), desire for self-autonomy (31%) and pain (31%). Half of the patients, particularly those striving for autonomy, persisted with their request until death, whereas 2 of 3 requests motivated by physical or psychological distress were not maintained. Sedation was administered to 3 patients in response to recurrent requests.ConclusionRequests for euthanasia in cancer patients are rare but may occur. Sometimes suffering is not relieved by palliative care and the request is maintained. Dealing with these patients puts caregivers in a difficult situation.

The author, an economist, rebuts the contention that human life cannot and should not be economically evaluated and argues that such evaluations are made implicitly and inconsistently, resulting in a reduction of human welfare. He presents an economic framework for the analysis of costs and benefits in which the focal point, as in most value systems, is the tradeoff between life and quality of life. Therefore, as the quality of life decreases, society's efforts to preserve life should decrease. If the valuation of life includes self evaluation, then there should be less effort to preserve the life of an individual who wishes to die. Richardson concludes that voluntary euthanasia is a limiting case in which society accepts the individual's valuation of life.

In Germany, physician-assisted euthanasia involves numerous risks for the attending physician under criminal and professional law. In the absence of clear legal provisions, four different categories of euthanasia have been developed in legal practice and the relevant literature: help in the dying process, direct active euthanasia, indirect active euthanasia and passive euthanasia. The so-called "help during the dying process" by administering medically indicated analgesic drugs without a life-shortening effect is exempt from punishment if it corresponds to the will of the patient. If the physician omits to give such analgesic drugs although the patient demands them, this is deemed a punishable act of bodily injury. The same applies if the physician administers analgesics against the will of the patient. Medically indicated pain treatment which has a potential or certain life-shortening effect (indirect active euthanasia) is permitted under certain conditions: if there are no alternative and equally suitable treatment options without the risk of shortening the patient's life, if the patient has given his consent to the treatment and if the physician does not act with the intention to kill. The deliberate killing of a dying or terminally ill patient for the purpose of ending his suffering (direct active euthanasia) is prohibited. This includes both deliberately killing a patient against or without his will (by so-called "angels of death") and the killing of a patient who expressly and earnestly demands such an act from his physician (killing on request/on demand). Physician-assisted suicide is generally not liable to punishment in Germany. Nevertheless, the action may be subject to punishment if the physician omits to rescue the life of an unconscious suicide victim. "Palliative sedation" is regarded as a special case. It may become necessary if certain symptoms in the terminal stage of a fatal disease unbearable for the patient cannot be controlled by any other
INTRODUCTION Euthanasia represents an ethical, social, legal and medical issue, which is being disputed more and more frequently worldwide. In Serbia, it is illegal and punishable by law and subject to a prison sentence. Euthanasia verbatim, meaning "good death", refers to the practice of ending a life in order to relieve pain and suffering. It can be voluntary, when a person knowingly declares the wish to end life, and involuntary, when relatives and family make decisions on behalf of patients in coma. It can be active, when a person applies a medical procedure to end life and passive, when medical procedures which can extend a patient's life are not applied. EUTHANASIA THROUGH HISTORY: The term was known in old Greece, and Hippocrates mentioned it in his oath, which is now taken by all doctors in the world, by which they pledge not to apply a medicine which can lead to death of the patients, nor to give such counsel. Euthanasia had its most vigorous impetus in the mid-20th century when it was being carried out deliberately in Nazi Germany. All leading religions from Christianity, over Buddhism, to Islam, are directly or indirectly against any kind of euthanasia. EUTHANASIA TODAY: At the beginning of the 21st century, euthanasia was legalized in several most developed countries in the world, among them the Netherlands, Belgium, Germany, Switzerland, Japan, India and some American and Mexican federal states. The World Medical Association from 82 countries has condemned euthanasia, and called all medical workers who practice euthanasia to reconsider their attitudes and to stop this practice.
Direct active euthanasia is prohibited in most countries while passive and indirect is not. However, many arguments against the legalization of voluntary active euthanasia are flawed. Ethical differences between active and passive or indirect euthanasia are difficult to maintain especially when the passivity of the actor causes death. The crucial point is not activity or passivity but respect for the autonomy of individual human beings. In particular there appears to be little ethical difference between active and indirect euthanasia. Indirect euthanasia has often been justified by the principle of double effect, which traces back to Thomas Aquinas. But resorting to this rule contains a logical fallacy. The principle of double effect does not allow foreseen and unwanted adverse effects of an action to occur when they are avoidable. In terminal sedation, an example for indirect euthanasia, hypoxemia and dehydration can easily be prevented by respirator therapy and fluid administration. Therefore the rule of double effect is not applicable. Indirect and direct active euthanasia cannot be ethically distinguished by resorting to the principle of double effect.

Following the recent revival of virtue ethics, a number of ethicists have discussed the moral problems surrounding euthanasia by drawing on concepts such as compassion, benevolence, death with dignity, mercy, and by inquiring whether euthanasia is compatible with human flourishing. Most of these writers assert, or simply assume, that their arguments concerning the morality of euthanasia also support their views with regard to legislation. I argue, against these writers, that legislation cannot and should not be based on our moral and religious beliefs concerning whether euthanasia allows a person to die a good death. I then outline an Aristotelian approach to the role of law and government in a good society, according to which the task of the legislator is not to ensure that people actually act virtuously, but is instead to make it possible for them to choose to live (and die) well by ensuring that they have access to the goods that are necessary for flourishing. In the second half of the paper I apply this approach to the question of whether voluntary active euthanasia should be legalised by asking (1) whether euthanasia always deprives people of the necessary conditions for flourishing, and (2) whether the option to request euthanasia is ever necessary for flourishing.

If we accept euthanasia for adults, should we also accept voluntary euthanasia for children? In 'Child Euthanasia: Should We Just Not Talk about It?', Luc Bovens answers this question affirmatively. Bovens examines five arguments against extending euthanasia to minors, the arguments being weightiness, capability of discernment, pressure, sensitivity and sufficient palliative care. He rejects each of these arguments. In this paper, I provide a rejoinder for each of his responses. I also critique his view that opponents of euthanasia have extra responsibility to promote palliative care. On the contrary, if euthanasia is legalised, advocates of euthanasia have a special obligation to promote improvements in palliative care.

Euthanasia is a complex medical procedure. Even though end of life decisions are common situations in health practice, there is a lack of consensus about their terminology. In this manuscript, the main concepts about this issue are defined and delimited; including active and passive euthanasia and limitation of therapeutic effort. Then, a revision is made about the international experience on euthanasia, to then go through the Chiles history in euthanasia and the populations opinion. In Chile, euthanasia is an act that has been removed from the social dialogue and legislation. In order to have an open discussion in our population about the issue, the debate has to be opened to the citizens, accompanied by clear medical information about the procedure.

The twitch interpolation technique is commonly employed to assess the completeness of skeletal muscle activation during voluntary contractions. Early applications of twitch interpolation suggested that healthy human subjects could fully activate most of the skeletal muscles to which the technique had been applied. More recently, however, highly sensitive twitch interpolation has revealed that even healthy adults routinely fail to fully activate a number of skeletal muscles despite apparently maximal effort. Unfortunately, some disagreement exists as to how the results of twitch interpolation should be employed to quantify voluntary activation. The negative linear relationship between evoked twitch force and voluntary force that has been observed by some researchers implies that voluntary activation can be quantified by scaling a single interpolated twitch to a control twitch evoked in relaxed muscle. Observations of non-linear evoked-voluntary force relationships have lead to the suggestion that the single interpolated twitch ratio can not accurately estimate voluntary activation. Instead, it has been proposed that muscle activation is better determined by extrapolating the relationship between evoked and voluntary force to provide an estimate of true maximum force. However, criticism of the single interpolated twitch ratio typically fails to take into account the reasons for the non-linearity of the evoked-voluntary force relationship. When these reasons are examined, it appears that most are even more challenging to the validity of extrapolation than they are to the linear equation. Furthermore, several factors that contribute to the observed non-linearity can be minimised or even eliminated with appropriate experimental technique. The detection of small activation deficits requires high resolution measurement of force and careful consideration of numerous experimental details such as the site of stimulation, stimulation intensity and the number of interpolated

The growing support for voluntary active euthanasia (VAE) is evident in the recently approved Dutch Law on Termination of Life on Request. Indeed, the debate over legalized VAE has increased in European countries, the United States, and many other nations over the last several years. The proponents of VAE argue that when a patient judges that the burdens of living outweigh the benefits, euthanasia can be justified. If some adults suffer to such an extent that VAE is justified, then one may conclude that some children suffer to this extent as well. In an attempt to alleviate the suffering of extremely ill neonates, the University Medical Center Groningen developed a protocol for neonatal euthanasia. In this article, I first present the ethical justifications for VAE and discuss how these arguments relate to euthanizing ill neonates. I then argue that, even if one accepts the justification for VAE in adults, neonatal euthanasia cannot be supported, primarily because physicians and parents can never accurately assess the suffering of children. I argue that without the testament of the patient herself as to the nature and magnitude of her suffering, physicians can never accurately weigh the benefits and burdens of a child's life, and therefore any such system would condemn to death some children whose suffering is not unbearable. I conclude that because the primary duty of physicians is to never harm their patients, neonatal euthanasia cannot be supported.
The passive form of euthanasia is legalized almost in every civilized country. Its active form is not a generally accepted legal institution. In Europe, active euthanasia is legalized only in The Netherlands, Belgium, Luxembourg and Switzerland. In Australia, the Act on the Rights of the Terminally Ill of 1995 legalized the institution of assisted suicide, which is not identical to active euthanasia. The difference lies in the fact that legalized active euthanasia means that the author of a murder is not punishable (under certain circumstances), whilst assisted suicide is not about murder, rather about suicide. In the first case, the patient is killed on his or her request by someone else. In the second case, the patient himself or herself executes the act of self-killing (by the assistance of a healthcare worker). In Australia, the institution of assisted suicide was repealed in 1997. Assisted suicide is legal in four USA member states: in Vermont, Washington, Montana and Oregon. In Uruguay, the active form of euthanasia has been legal since 1932.

A recent survey showed that less than half of Dutch physicians would find it conceivable to grant a request for euthanasia from a patient suffering from psychiatric disease or dementia, or who is tired of life. Because of a broader interpretation by the Regional Review Committees of the official criteria for due care, all recent cases of euthanasia in these specific groups of patients had been accepted. In this commentary it is argued that, following recent social developments in the Netherlands (including cuts in provision of care for the elderly and of mental health care, and a narrowed view about end-of-life issues), the official euthanasia criteria for due care are no longer suitable if we are to avoid a 'slippery slope' effect in cases such as those mentioned above. The criteria of a) a voluntary and well-considered request and b) absence of reasonable treatment alternatives are particularly under pressure. A plea is hold for a return to stricter interpretation of the criteria.
In a questionnaire to medical students in Sweden, only 6 out of 135 answered that they wanted voluntary active euthanasia to be legalized. However, most of the students were of the opinion that the charges brought against the physician could be withdrawn pending assessment by a public prosecutor (55), or alternatively, that remission of sentence could be granted pending assessment by a court (45). A somewhat smaller group (26) answered that prison corresponding to the sentence for manslaughter was reasonable. Only 3 students considered voluntary active euthanasia to be murder. Legal monitoring of each case of active euthanasia was very important to these medical students, but many answered that under specific conditions there should be no punishment.

Advances in medicine can reduce active euthanasia of newborns with severe anomalies or unusual prematurity, but they cannot eliminate it. In the Netherlands, voluntary active euthanasia among adults and adolescents has been allowed since 2002, when the so-called Groningen Protocol (GP) was formulated as an extension of the law on extremely premature and severely ill newborns. It is maintained that, at bioethical level, it serves the principle of beneficence. Other European countries do not accept the GP, including Belgium. Admissibility of active euthanasia is a necessary, though inadequate, condition for acceptance of the GP. Greece generally prohibits euthanasia, although the legal doctrine considers some of the forms of euthanasia permissible, but not active or involuntary euthanasia. The wide acceptance of passive newborns euthanasia, especially when the gestational age of the newborns is 22-25 weeks ("grey zone"), admissibility of practices within the limits between active and passive euthanasia (e.g., withholding/withdrawing), of "indirect active euthanasia" and abortion of the late fetus, the tendency to accept after-birth-abortion (infanticide) in the bioethical theory, the lower threshold for application of withdrawing in neonatal intensive care units compared with pediatric intensive care units, all the above advocate wider acceptance of the GP. However, the GP paves the way for a wide application of involuntary (or pseudo-voluntary) euthanasia (slippery slope) and contains some ambiguous concepts and requirements (e.g., "unbearable suffering"). It is suggested that the approach to the sensitive and controversial ethical dilemmas concerning the severely ill newborns is done not through the GP, but rather, through a combination of virtue bioethics (especially in the countries of the so-called "Mediterranean bioethical zone") and of the principles of principlism which is enriched, however, with the "principle of mutuality" (enhancement of all values and

Each of the Benelux countries (Belgium, Luxembourg, Netherlands) has enacted legislation that partially decriminalises euthanasia, defined as an act that intentionally terminates someone's life at their request. In the Netherlands and Luxembourg, but not in Belgium, the legislation partially decriminalised assisted suicide at the same time. In all three countries, euthanasia can only be performed by a doctor, in response to the patient's voluntary and well-considered request, and for patients who have an incurable disease that causes unbearable suffering, without any prospect of relief. In the Netherlands, minors can request euthanasia as of the age of 12 years. In 2011, reported euthanasia accounted for about 1% of deaths in Belgium and 3% in the Netherlands. In 75% of cases, cancer was the disease leading to a request for euthanasia. In the Netherlands, the number of cases of euthanasia reported by doctors in surveys matches the number that is officially declared. In Belgium, it is thought that there are as many unreported as reported cases of euthanasia. Since the enactment of euthanasia legislation, fewer deaths involve the intentional administration of lethal drugs without an explicit request from the patient.
Historians of medical ethics have found that active euthanasia, in the sense of intentionally hastening the death of terminally-ill patients, was considered unacceptable in the Christian West before the 1870s. This paper presents a range of early modern texts on the issue which reflect a learned awareness of practices designed to shorten the lives of dying patients which were widely accepted among the lay public. Depriving the dying abruptly of their head-rest or placing them flat on the cold floor may strike us as merely symbolic today, but early moderns associated such measures with very concrete and immediate effects. In this sense, the intentional hastening of death in agonising patients had an accepted place in pre-modern popular culture. These practices must, however, be put into their proper context. Death was perceived more as a transition to the after-life and contemporary notions of dying could make even outright suffocation appear as an act of compassion which merely helped the soul depart from the body at the divinely ordained hour of death. The paper concludes with a brief comparison of early modern arguments with those of today.

This article examines the legal regulation of active voluntary euthanasia and assisted suicide in Australia. The Dying with Dignity Bill 2009 (Tas), which was recently defeated by the Tasmanian Parliament, is discussed, as well as other jurisdictions' past and present legislative developments in this context. The recent case law is also considered to ascertain how "mercy killing" or assisted suicide cases are dealt with by the criminal justice system, with particular reference to the case of R v Justins  NSWSC 1194. This is followed by a critical evaluation of the key arguments for and against euthanasia. The article concludes by examining the significance of the Tasmanian Bill and the implications of such legislation.

Several countries have adopted laws that regulate physician assistance in dying. Such assistance may consist of providing a patient with a prescription of lethal medication that is self-administered by the patient, which is usually referred to as (physician) assistance in suicide, or of administering lethal medication to a patient, which is referred to as euthanasia. The main aim of regulating physician assistance in dying is to bring these practices into the open and to provide physicians with legal certainty. A key condition in all jurisdictions that have regulated either assistance in suicide or euthanasia is that physicians are only allowed to engage in these acts upon the explicit and voluntary request of the patient. All systems that allow physician assistance in dying have also in some way included the notion that physician assistance in dying is only accepted when it is the only means to address severe suffering from an incurable medical condition. Arguments against the legal regulation of physician assistance in dying include principled arguments, such as the wrongness of hastening death, and arguments that emphasize the negative consequences of allowing physician assistance in dying, such as a devaluation of the lives of older people, or people with chronic disease or disabilities. Opinion polls show that some form of accepting and regulating euthanasia and physician assistance in suicide is increasingly supported by the general population in most western countries. Studies in countries where physician assistance in dying is regulated suggest that practices have remained rather stable in most jurisdictions and that physicians adhere to the legal criteria in the vast majority of cases.

The consequences of baclofen intake on voluntary motor behaviors remain unclear. We studied the effects of single oral doses of baclofen on voluntary, isometric knee extension torques and surface and single motor unit (MU) electromyographic (EMG) activity from the vastus lateralis in 11 individuals without neurological injury. Examination of submaximal to maximal contractions of varying duration performed pre- and post-baclofen ingestion revealed significant decreases in maximal knee torques and EMG magnitude, accompanied by an increase in slope of the torque-EMG relation. A decreased slope of the torque-MU firing rate relation was also demonstrated post-baclofen, but without changes in minimal firing rates or recruitment forces. During sustained contractions at < or =25% of maximal voluntary torque elicited after baclofen ingestion, increased EMG activity was observed without significant differences in MU firing rates. Our results demonstrate a clear reduction in the maximal torque-generating ability following baclofen. Specific changes in MU firing patterns indicate that weakness may be due partly to reduced motoneuronal excitability, although use of MU discharge patterns to assess these effects is limited in its sensitivity.

The attitudes of a random sample of 614 Catholic and Protestant clergymen from the Cleveland area were analyzed in relation to the following: 1) acceptance of euthanasia; 2) the establishment of legal guidelines; and 3) the similarity between euthanasia and abortion. In general the clergy were not opposed to all forms of euthanasia. They tended to make strong distinctions between passive and active euthanasia. Active euthanasia was highly unacceptable to the clergy, but they viewed passive euthanasia more favorably. There was a definite ranking in priority of the different circumstances under which the termination of life-supporting techniques would be acceptable to the clergy. Also significant was the fact that they did not tend to evaluate the issues surrounding euthanasia completely from a spiritual, or sacred perspective. Both Protestants and Catholics tended to approve of passive euthanasia, but they highly disapproved of active euthanasia. Catholics were significantly more opposed to both forms of euthanasia. In general conservative Protestants were more opposed to passive euthanasia on most dimensions than were Catholics. Both Catholic and Protestant clergy showed fear that official approval of types of euthanasia would spread into abuses. Although spiritually oriented clergy tended to show somewhat less unfavorable views on euthanasia when compared with abortion, generally, appreciable differences or role types on this particular sub-dimension was lacking.

Voluntary control of oscillatory activity represents a key target in the self-regulation of brain function. Using a real-time closed-loop paradigm and simultaneous macro- and micro-electrode recordings, we studied the effects of self-induced intracortical oscillatory activity (4–8 Hz) in seven neurosurgical patients. Subjects learned to robustly and specifically induce oscillations in the target frequency, confirmed by increased oscillatory event density. We have found that the session-to-session variability in performance was explained by the functional long-range decoupling of the target area suggesting a training-induced network reorganization. Downstream effects on more local activities included progressive cross-frequency-coupling with gamma oscillations (30–120 Hz), and the dynamic modulation of neuronal firing rates and spike timing, indicating an improved temporal coordination of local circuits. These findings suggest that effects of voluntary control of intracortical oscillations can be exploited to specifically target plasticity processes to reconfigure network activity, with a particular relevance for memory function or skill acquisition.

Muscle damage reduces voluntary force after eccentric exercise but impaired neural drive to the muscle may also contribute. To determine whether the delayed-onset muscle soreness, which develops approximately 1 day after exercise, reduces voluntary activation and to identify the possible site for any reduction, voluntary activation of elbow flexor muscles was examined with both motor cortex and motor nerve stimulation. We measured maximal voluntary isometric torque (MVC), twitch torque, muscle soreness and voluntary activation in eight subjects before, immediately after, 2 h after, 1, 2, 4 and 8 days after eccentric exercise. Motor nerve stimulation and motor cortex stimulation were used to derive twitch torques and measures of voluntary activation. Eccentric exercise immediately reduced the MVC by 38 +/- 3% (mean +/- s.d., n = 8). The resting twitch produced by motor nerve stimulation fell by 82 +/- 6%, and the estimated resting twitch by cortical stimulation fell by 47 +/- 15%. While voluntary torque recovered after 8 days, both measures of the resting twitch remained depressed. Muscle tenderness occurred 1-2 days after exercise, and pain during contractions on days 1-4, but changes in voluntary activation did not follow this time course. Voluntary activation assessed with nerve stimulation fell 19 +/- 6% immediately after exercise but was not different from control values after 2 days. Voluntary activation assessed by motor cortex stimulation was unchanged by eccentric exercise. During MVCs, absolute increments in torque evoked by nerve and cortical stimulation behaved differently. Those to cortical stimulation decreased whereas those to nerve stimulation tended to increase. These findings suggest that reduced voluntary activation contributes to the early force loss after eccentric exercise, but that it is not due to muscle soreness. The impairment of voluntary activation to nerve stimulation but not motor cortical stimulation suggests that the activation

Although maximal voluntary contraction (MVC) force is reduced during pain, studies using interpolated twitch show no consistent reduction of voluntary muscle drive. The present study aimed to test if the reduction in MVC force during acute experimental pain could be explained by increased activation of antagonist muscles, weak voluntary activation at baseline, or changes in force direction. Twenty-two healthy volunteers performed maximal voluntary isometric knee extensions before, during, and after the effects of hypertonic (pain) and isotonic (control) saline injections into the infrapatellar fat pad. The MVC force, voluntary activation, electromyographic (EMG) activity of agonist, antagonist, and auxiliary (hip) muscles, and pain cognition and anxiety scores were recorded. MVC force was 9.3% lower during pain than baseline (p < 0.001), but there was no systematic change in voluntary activation. Reduced MVC force during pain was variable between participants (SD: 14%), and was correlated with reduced voluntary activation (r = 0.90), baseline voluntary activation (r = − 0.62), and reduced EMG amplitude of agonist and antagonist muscles (all r > 0.52), but not with changes in force direction, pain or anxiety scores. Hence, reduced MVC force during acute pain was mainly explained by deficits in maximal voluntary drive. PMID:27559737

Euthanasia was legalized in Belgium in 2002 for adults under strict conditions. The patient must be in a medically futile condition and of constant and unbearable physical or mental suffering that cannot be alleviated, resulting from a serious and incurable disorder caused by illness or accident. Between 2005 and 2007, 4 patients (3 in Antwerp and 1 in Liège) expressed their will for organ donation after their request for euthanasia was granted. Patients were aged 43 to 50 years and had a debilitating neurologic disease, either after severe cerebrovascular accident or primary progressive multiple sclerosis. Ethical boards requested complete written scenario with informed consent of donor and relatives, clear separation between euthanasia and organ procurement procedure, and all procedures to be performed by senior staff members and nursing staff on a voluntary basis. The euthanasia procedure was performed by three independent physicians in the operating room. After clinical diagnosis of cardiac death, organ procurement was performed by femoral vessel cannulation or quick laparotomy. In 2 patients, the liver, both kidneys, and pancreatic islets (one case) were procured and transplanted; in the other 2 patients, there was additional lung procurement and transplantation. Transplant centers were informed of the nature of the case and the elements of organ procurement. There was primary function of all organs. The involved physicians and transplant teams had the well-discussed opinion that this strong request for organ donation after euthanasia could not be waived. A clear separation between the euthanasia request, the euthanasia procedure, and the organ procurement procedure is necessary.

Objectives To study motor activation patterns of voluntary and reflex cough adjusted for cough flow rates. Methods Surface electromyography (EMG) and cough flow rate were measured in 10 healthy volunteers. Voluntary cough was assessed for 20 efforts in each quintile of increasing cough flow rate. Reflex cough was assessed for 25 efforts produced by nebulised l‐tartaric acid. EMG was recorded over the expiratory (rectus abdominis, obliques, lower intercostals) and accessory (trapezius, pectoralis major, deltoid, latissimus dorsi) muscles. EMG activity, burst duration and onset were compared for each quintile of voluntary cough, and between voluntary and reflex cough matched for cough flow rate. Results EMG activity and burst duration of expiratory and accessory muscles during voluntary cough increased in proportion to cough flow. Expiratory muscles had longer EMG burst duration (difference 68 ms (95% CI 34 to 102), p<0.01) and earlier onset of EMG activity (difference 44 ms (95% CI 20 to 68), p<0.0001) compared with accessory muscles. EMG activity in all muscles was increased (mean 110.2% v 56.1%, p<0.001) and burst duration (mean 206 ms v 280 ms, p = 0.013) decreased in reflex cough compared with voluntary cough of equal flow rate. There were no differences in EMG onset (difference 8 ms (95% CI 25 to −9) or burst duration (difference 27 ms (95% CI 58 to −4) between expiratory and accessory muscles. Conclusions Functional organisation of motor activity differs between voluntary and reflex cough. Voluntary cough is characterised by sequential activation whereas reflex cough is associated with early and simultaneous activation of expiratory and accessory muscles. PMID:16601089

Issues relating to voluntary euthanasia that are currently being debated by Australian society are distinctly different from those encountered by battlefield doctors. Doctors in war undertake to treat those affected by conflict; their participation in euthanasia challenges the profession's definition of "duty of care". Euthanasia must be distinguished from "triage" and medical withdrawal of care (which are decided within a medical facility where, although resources may be limited, comfort care can be provided in the face of treatment futility). Battlefield euthanasia is a decision made, often immediately after hostile action, in the face of apparently overwhelming injuries; there is often limited availability of pain relief, support systems or palliation that would be available in a civilian environment. The battlefield situation is further complicated by issues of personal danger, the immediacy of decision making and difficulties with distinguishing civilians from combatants. Regardless of the circumstances on a battlefield, doctors, whether they are civilians or members of a defence force, are subject to the laws of armed conflict, the special provisions of the Geneva Conventions and the ethical codes of the medical profession.

In order to explore interactive effects of voluntarily generated rotational stimuli on evoked vestibular responses, experiments were performed using a rotation chair in which the subject either controlled the angular motion by voluntary movement of his upper and lower limbs, or was passive-rotation being controlled by a servomotor and electromagnetic brake. In two experiments, carried out on 8 and 9 subjects respectively, it was found that cessation of sustained passive rotation by voluntary limb actions strongly suppressed the postrotational turning sensation but did not alter the evoked nystagmus. Limb movements that were directionally concordant with muscle torque in generating body rotation yielded arthrokinetic effects which augmented perrotational nystagmus and sustained the sensation of turning. The postrotational sensation of turning and postrotational nystagmus produced by voluntary cessation of active rotation were reduced relative to responses produced by passive turning and stopping. The Purkinje effect induced by postrotational head movements was similarly reduced following voluntary cessation of active rotation.

The biceps or the posterior deltoid can be transferred to improve elbow extension function for many individuals with C5 or C6 quadriplegia. Maximum strength after elbow reconstruction is variable; the patient’s ability to voluntarily activate the transferred muscle to extend the elbow may contribute to the variability. We compared voluntary activation during maximum isometric elbow extension following biceps transfer (n = 5) and deltoid transfer (n = 6) in three functional postures. Voluntary activation was computed as the elbow extension moment generated during maximum voluntary effort divided by the moment generated with full activation, which was estimated via electrical stimulation. Voluntary activation was on average 96% after biceps transfer and not affected by posture. Individuals with deltoid transfer demonstrated deficits in voluntary activation, which differed by posture (80% in horizontal plane, 69% in overhead reach, and 70% in weight-relief), suggesting inadequate motor re-education after deltoid transfer. Overall, individuals with a biceps transfer better activated their transferred muscle than those with a deltoid transfer. This difference in neural control augmented the greater force-generating capacity of the biceps leading to increased elbow extension strength after biceps transfer (average 9.37 N-m across postures) relative to deltoid transfer (average 2.76 N-m across postures) in our study cohort.

The number of dementia patients requesting euthanasia in the Netherlands has increased over the past five years. The issue is highly controversial. In this contribution we discuss some of the main arguments: the nature of suffering, the voluntariness of the request and the role of the physician. We argue that society has a duty to care for patients who suffer from dementia and to make their lives as good and comfortable as possible. We also argue that it can be morally acceptable for those who do not want to continue their life with dementia to choose to die. The choice can be based on good reasons.

The experience of the Netherlands in relation with the legalization and practice of euthanasia is better known in Spain than the Belgian experience in this matter. But the historical process of social debate in Belgium has many specific details which should be known by Spanish healthcare professionals, bioethicists, politicians and lawyers. This paper begins with a comparative analysis of both countries: Spain and Belgium and follows with a description of the milestones of the historical process of debating and, finally, passing the Belgian Law on Euthanasia in 2002. The next chapter consists of a description of the main contents of this important Law. The paper continues then with an approach to the epidemiology of the practice of euthanasia in Belgium and finishes with a description of the different positions of the actors of the process. Two positions are described more in depth: the opinion of the specialists in palliative care, and the opinion of the Catholic Church. The paper ends underlining the reason for the incorporation of the Belgian experience on euthanasia to the debate about the possibility of legalizing euthanasia in Spain.

Euthanasia has become the subject of ethical and political debate in many countries including Mexico. Since many physicians are deeply concerned about euthanasia, due to their crucial participation in its decision and implementation, it is important to know the psychological meaning that the term 'euthanasia' has for them, as well as their attitudes toward this practice. This study explores psychological meaning and attitudes toward euthanasia in 546 Mexican subjects, either medical students or physicians, who were divided into three groups: a) beginning students, b) advanced students, and c) physicians. We used the semantic networks technique, which analyzed the words the participants associated with the term 'euthanasia'. Positive psychological meaning, as well as positive attitudes, prevailed among advanced students and physicians when defining euthanasia, whereas both positive and negative psychological meaning together with more ambivalent attitudes toward euthanasia predominated in beginning students. The findings are discussed in the context of a current debate on a bill proposing active euthanasia in Mexico City.

Involuntary physical activity induced by the avoidance of electrical shock leads to improved endurance exercise capacity in animals. However, it remains unknown whether voluntary stand-up physical activity (SPA) without forced simulating factors improves endurance exercise capacity in animals. We examined the eff ects of SPA on body weight, cardiac function, and endurance exercise capacity for 12 weeks. Twelve male Sprague-Dawley rats (aged 8 weeks, n=6 per group) were randomly assigned to a control group (CON) or a voluntary SPA group. The rats were induced to perform voluntary SPA (lifting a load equal to their body weight), while the food height (18.0 cm) in cages was increased progressively by 3.5 every 4 weeks until it reached 28.5 cm for 12 weeks. The SPA group showed a lower body weight compared to the CON group, but voluntary SPA did not affect the skeletal muscle and heart weights, food intake, and echocardiography results. Although the SPA group showed higher grip strength, running time, and distance compared to the CON group, the level of irisin, corticosterone, genetic expression of mitochondrial biogenesis, and nuclei numbers were not affected. These findings show that voluntary SPA without any forced stimuli in rats can eff ectively reduce body weight and enhance endurance exercise capacity, suggesting that it may be an important alternative strategy to enhance endurance exercise capacity.

There are an infinite variety of attitudes to euthanasia, each individual response to the concept being influenced by many factors. Consequently there is a literature on the subject ranging from the popular article to papers in specialized journals. This study, however, has taken a well defined sample of people, inviting them to answer a questionnaire which was designed to elicit their attitudes to euthanasia in a way which could be analysed statistically. Nor surprisingly attitudes appeared to 'harden' as those answering the questionnaire grew more experienced in dealing with patients and also more professionally established. Thus it was found that of the seven groups questioned practising physicians showed more positive attitudes to euthanasia and their responses did not differ significantly from those of senior medical students. It is these groups which actually or potentially have to resolve the clinical dilemma posed by the dying patient. PMID:859163
Right to life -as the prohibition of intentionally and arbitrarily taking life, even with authorization of the concerned one- is an internationally recognized right. In many countries, debate regarding euthanasia is more centered in its convenience, social acceptability and how it is regulated, than in its substantial legitimacy. Some argue that euthanasia should be included as part of clinical practice of health professionals, grounded on individual's autonomy claims-everyone having the liberty to choose how to live and how to die. Against this, others sustain that life has a higher value than autonomy, exercising autonomy without respecting the right to life would become a serious moral and social problem. Likewise, euthanasia supporters some-times claim a 'right to live with dignity', which must be understood as a personal obligation, referred more to the ethical than to the strictly legal sphere. In countries where it is already legalized, euthanasia practice has extended to cases where it is not the patient who requests this but the family or some healthcare professional, or even the legal system-when they think that the patient is living in a condition which is not worthy to live. Generalization of euthanasia possibly will end in affecting those who need more care, such as elder, chronically ill or dying people, damaging severely personal basic rights. Nature, purpose and tradition of medicine rule out the practice of euthanasia, which ought not be considered a medical act or legitimately compulsory for physicians. Today's medicine counts with effective treatments for pain and suffering, such as palliative care, including sedative therapy, which best preserves persons dignity and keeps safe the ethos of the medical profession.
Timely euthanasia of feeder cattle can minimize suffering of cattle that have little hope of recovery or pain abatement. Euthanasia techniques are described, including primary and secondary steps to ensure humane death. Considerations are discussed to ensure rendered product from euthanized cattle will be safe. A necropsy technique that is time efficient and thorough is outlined. An important aspect is minimizing the number of detached body organs, thereby making it easier to remove the necropsied animal. A necropsy data collection system is discussed that uses check-boxes to record findings. A link to a database that can be downloaded is included.
Euthanasia should be considered one of the main philosophical topics of today's medical practice. In view of the technological advances in medicine, the economic pressure in the majority of our medical systems, and a deep alteration and modification in the patient-physician relationship, the status of some patients in their final days should be reconsidered. The increased awareness of the public about euthanasia and related topics (pain, assisted suicide, dying with dignity, etc.) suggests that a urgent dialogue between lay persons and physicians is needed.

Hypothesis Neuromuscular inhibition of the infraspinatus would be greater and external rotation muscle force would be lower after a simulated game compared with pregame values. Materials and methods The sample included 21 uninjured, asymptomatic high school–aged baseball pitchers. Maximum volitional shoulder external rotation strength was assessed before and after a simulated game with a clinical dynamometer. Voluntary activation of the infraspinatus was assessed during strength testing by a modified burst superimposition technique. Performance-related fatigue was assessed by monitoring pitch velocity, and global fatigue was assessed by subject self-report before and after the game. Statistical testing included paired and independent t tests, with α ≤ 05. Results There was no difference between throwing and non-throwing shoulder external rotation strength (P = .12) or voluntary infraspinatus activation (P = .27) before the game. After the game, voluntary activation was significantly lower in the throwing limb compared with pregame activation levels (P = .01). Lower external rotation strength after the game approached statistical significance (P =.06). Pitch velocity was lower in the final inning compared with first-inning velocity (P = .01), and fatigue was significantly greater after the game (P = .01). Conclusions Voluntary infraspinatus muscle activation is a mechanism contributing to external rotation muscle weakness in the fatigued pitcher. Understanding mechanisms contributing to muscle weakness is necessary to develop effective injury prevention and rehabilitation programs. Treatment techniques that enhance neuromuscular activation may be a useful strategy for enhancing strength in this population. Level of evidence Basic Science Study, Kinesiology Study. PMID:21831667

The purpose of this study was to investigate the relationship between EEG-derived motor activity-related cortical potential (MRCP) and voluntary muscle activation. Eight healthy volunteers participated in two experimental sessions. In one session, subjects performed isometric elbow-flexion contractions at four intensity levels [10%, 35%, 60%, and 85% maximal voluntary contraction (MVC)]. In another session, a given elbow-flexion force (35% MVC) was generated at three different rates (slow, intermediate, and fast). Thirty to 40 contractions were performed at each force level or rate. EEG signals were recorded from the scalp overlying the supplementary motor area (SMA) and contralateral sensorimotor cortex, and EMG signals were recorded from the skin surface overlying the belly of the biceps brachii and brachioradialis muscles during all contractions. In each trial, the force was used as the triggering signal for MRCP averaging. MRCP amplitude was measured from the beginning to the peak of the negative slope. The magnitude of MRCP from both EEG recording locations (sensorimotor cortex and SMA) was highly correlated with elbow-flexion force, rate of rising of force, and muscle EMG signals. These results suggest that MRCP represents cortical motor commands that scale the level of muscle activation.

The objective of this study was to assess the nature of muscle weakness in both legs after stroke compared with able-bodied control individuals and to examine whether there is a relationship between the degree of muscle weakness and coactivation of knee extensors and flexors as well as voluntary activation capacity of knee extensors of both paretic and non-paretic legs and indices of functional performance. Maximal voluntary isometric torques of knee extensors (MVCe) and flexors (MVCf) were determined in 14 patients (bilaterally) and 12 able-bodied controls. Simultaneous measurements were made of torque and surface EMG from agonist and antagonist muscles. Coactivation was calculated. Supramaximal triplets were evoked with electrical stimulation to estimate maximal torque capacity and degree of voluntary activation of knee extensors. MVCs, activation and coactivation parameters were correlated to scores of seven functional performance tests. MVCe, MVCf and voluntary activation were lower in paretic lower limb (PL) compared with both non-paretic lower limb (NL) and control. Besides, all these parameters of NL were also lower than control. Electrically evoked torque capacity of knee extensors of PL was about 60% of both NL and control, which were not significantly different from each other. Strong significant correlations between strength, as well as voluntary activation, and functional performance were found. Coactivation did not correlate well with functional performance. Thus, whereas for NL activation failure can explain weakness, for PL both activation failure and reduced intrinsic torque capacity are responsible for the severe weakness. Activation capacity and muscle strength correlated strongly to functional performance, while coactivation did not.

Palliative sedation at the end of life has become an important last-resort treatment strategy for managing refractory symptoms as well as a topic of controversy within palliative care. Furthermore, palliative sedation is prominent in the public debate about the possible legalisation of voluntary assisted dying (physician-assisted suicide and euthanasia). This article attempts to demonstrate that palliative sedation is fundamentally different from euthanasia when it comes to intention, procedure, outcome and the status of the person. Nonetheless, palliative sedation in its most radical form of terminal deep sedation parallels euthanasia in one respect: both end the experience of suffering. However, only the latter intentionally ends life and also has this as its goal. There is the danger that deep sedation could bring death forward in time due to particular side effects of the treatment. Still that would, if it happens, not be intended, and accordingly is defensible in view of the doctrine of double effect.

Euthanasia has been heatedly discussed in Western countries over the last years. Only a few nations have legalized euthanasia or physician assisted suicide with the Dutch at the forefront of that field. Proponents of euthanasia mostly argue for euthanasia on two grounds. Firstly, that the patient has a right to die and secondly, that there is no substantial difference between euthanasia and palliative care. In this paper I will argue against both of the above. I discuss the arguments against euthanasia which are in principle four. Firstly, it is held by many that taking a human life is wrong under all circumstances. Secondly, that it is an unjustifiable demand to ask a person to take another person's life. In relation to that argument, euthanasia is not in accordance with the basic principles of medicine and nursing as they have evolved over the years and could therefore easily disrupt the therapeutic relationship. Thirdly, as shown from Holland there is empirical evidence that euthanasia is not under good enough surveillance and therefore invites misuse. Fourthly, even though euthanasia might possibly be justifiable under certain circumstances, legalisation might well invite abuse because of the message and pressure that the option places on both patients and professionals in terminal care. My answer to the euthanasia demand is palliative care, where dialogue between the patient and doctor is central. But the dialogue cannot be effective, unless both partners are willing and able to engage in sincere and frank conversations.

Objectives To expand voluntary active-learning opportunities for bachelor of pharmacy students enrolled in a third-year human physiology and pharmacology course and determine whether the additional course components improved learning outcomes. Design Additional voluntary active-learning opportunities including a large-class tutorial, additional formative assessment, and an online discussion were added to the Respiratory Physiology Module of the course. Examination scores were compared with those from previous years. A questionnaire was administered to assess students' perception of the active-learning components. Assessment Mean examination scores increased from 69.3% ± 24.4% in 2003 to 88.9% ± 13.4% in 2004 and 86.9% ± 17.6% in 2005, after the addition of the active-learning components. Students' overall perception of the value of the active-learning activities was positive. Summary The addition of voluntary active-learning course components to a required pharmacy course resulted in improved student examination scores, and decreased failure rate, and were accomplished at low cost and with little additional staff time.

With fatiguing exercise, firing of group III/IV muscle afferents reduces voluntary activation and force of the exercised muscles. These afferents can also act across agonist/antagonist pairs, reducing voluntary activation and force in nonfatigued muscles. We hypothesized that maintained firing of group III/IV muscle afferents after a fatiguing adductor pollicis (AP) contraction would decrease voluntary activation and force of AP and ipsilateral elbow flexors. In two experiments (n = 10) we examined voluntary activation of AP and elbow flexors by measuring changes in superimposed twitches evoked by ulnar nerve stimulation and transcranial magnetic stimulation of the motor cortex, respectively. Inflation of a sphygmomanometer cuff after a 2-min AP maximal voluntary contraction (MVC) blocked circulation of the hand for 2 min and maintained firing of group III/IV muscle afferents. After a 2-min AP MVC, maximal AP voluntary activation was lower with than without ischemia (56.2 ± 17.7% vs. 76.3 ± 14.6%; mean ± SD; P < 0.05) as was force (40.3 ± 12.8% vs. 57.1 ± 13.8% peak MVC; P < 0.05). Likewise, after a 2-min AP MVC, elbow flexion voluntary activation was lower with than without ischemia (88.3 ± 7.5% vs. 93.6 ± 3.9%; P < 0.05) as was torque (80.2 ± 4.6% vs. 86.6 ± 1.0% peak MVC; P < 0.05). Pain during ischemia was reported as Moderate to Very Strong. Postfatigue firing of group III/IV muscle afferents from the hand decreased voluntary drive and force of AP. Moreover, this effect decreased voluntary drive and torque of proximal unfatigued muscles, the elbow flexors. Fatigue-sensitive group III/IV muscle nociceptors act to limit voluntary drive not only to fatigued muscles but also to unfatigued muscles within the same limb.

This paper re-evaluates euthanasia and assisted suicide from the perspective of eudaimonia, the ancient Greek conception of happiness across one's whole life. It is argued that one cannot be said to have fully flourished or had a truly happy life if one's death is preceded by a period of unbearable pain or suffering that one cannot avoid without assistance in ending one's life. While death is to be accepted as part of life, it should not be left to nature to dictate the way we die, and it is fundamentally unjust to grant people liberal latitude in how they live their lives while granting them little control over the conclusion of their life narratives. Three objections to this position are considered and rejected; the paper also offers an explanation of why we think killing can be a benefit. Ultimately, euthanasia may be necessary in some cases in order to achieve eudaimonia.

Numbers of overweight and obese individuals are increasing in the United States and globally, and, correspondingly, the associated health care costs are rising dramatically. More than one-third of children are currently considered obese with a predisposition to type 2 diabetes, and it is likely that their metabolic conditions will worsen with age. Physical inactivity has also risen to be the leading cause of many chronic, noncommunicable diseases (NCD). Children are more physically inactive now than they were in past decades, which may be due to intrinsic and extrinsic factors. In rodents, the amount of time engaged in spontaneous activity within the home cage is a strong predictor of later adiposity and weight gain. Thus, it is important to understand primary motivators stimulating physical activity (PA). There are normal sex differences in PA levels in rodents and humans. The perinatal environment can induce sex-dependent differences in PA disturbances. This Review considers the current evidence for sex differences in PA in rodents and humans. The rodent studies showing that early exposure to environmental chemicals can shape later adult PA responses are discussed. Next, whether there are different motivators stimulating exercise in male vs. female humans are examined. Finally, the brain regions, genes, and pathways that modulate PA in rodents, and possibly by translation in humans, are described. A better understanding of why each sex remains physically active through the life span could open new avenues for preventing and treating obesity in children and adults. © 2016 Wiley Periodicals, Inc.

We investigated whether altered peripheral and/or corticospinal excitatory output and voluntary activation are implicated in hypohydration-induced reductions in muscle isometric and isokinetic (90°.s−1) strength. Nine male athletes completed two trials (hypohydrated, euhydrated) comprising 90 min cycling at 40°C, with body weight losses replaced in euhydrated trial. Peripheral nerve and transcranial magnetic stimulations were applied during voluntary contractions pre- and 40 min post-exercise to quantify voluntary activation and peripheral (M-wave) and corticospinal (motor evoked potential) evoked responses in m. vastus medialis. Both maximum isometric (−15.3±3.1 vs −5.4±3.5%) and isokinetic eccentric (−24.8±4.6 vs −7.3±7.2%) torque decreased to a greater extent in hypohydrated than euhydrated trials (p<0.05). Half relaxation time of the twitch evoked by peripheral nerve stimulation during maximal contractions increased after exercise in the hypohydrated (21.8±9.3%) but stayed constant in the euhydrated (1.6±10.7%; p = 0.017) condition. M-wave amplitude during maximum voluntary contraction increased after exercise in the heat in hypohydrated (10.7±18.0%) but decreased in euhydrated condition (−17.4±16.9%; p = 0.067). Neither peripheral nor cortical voluntary activation were significantly different between conditions. Motor evoked potential amplitude increased similarly in both conditions (hypohydrated: 25.7±28.5%; euhydrated: 52.9±33.5%) and was accompanied by lengthening of the cortical silent period in euhydrated but not hypohydrated condition (p = 0.019). Different neural strategies seem to be adopted to regulate neural drive in the two conditions, with increases in inhibitory input of either intracortical or corticospinal origin during the euhydrated trial. Such changes were absent in the hypohydrated condition, yet voluntary activation was similar to the euhydrated condition, perhaps due to smaller increases in excitatory

Numerous questionnaire studies on attitudes towards euthanasia produced conflicting results, precluding any general conclusion. This might be due to the fact that human behavior can be influenced by automatically triggered attitudes, which represent ingrained associations in memory and cannot be assessed by standard questionnaires, but require indirect measures such as reaction times (RT) or electroencephalographic recording (EEG). Event related potentials (ERPs) of the EEG and RT during an affective priming task were assessed to investigate the impact of automatically triggered attitudes and were compared to results of an explicit questionnaire. Explicit attitudes were ambivalent. Reaction time data showed neither positive nor negative associations towards euthanasia. ERP analyses revealed an N400 priming effect with lower mean amplitudes when euthanasia was associated with negative words. The euthanasia-related modulation of the N400 component shows an integration of the euthanasia object in negatively valenced associative neural networks. The integration of all measures suggests a bottom-up process of attitude activation, where automatically triggered negative euthanasia-relevant associations can become more ambiguous with increasing time in order to regulate the bias arising from automatic processes. These data suggest that implicit measures may make an important contribution to the understanding of euthanasia-related attitudes.

1. Motor unit synchronization has been studied in human first dorsal interosseous muscle. 2. Two needle electrodes were inserted into the muscle and the activity of pairs of motor units recorded. 3. Pre- and post-stimulus histograms of the firing of unit pairs showed a narrow central peak of duration 1.3-9.3 ms (88% of sample in the range 1-6 ms; mode 3.0 ms), together with a variable amount of synchronization of somewhat longer duration. 4. For the duration of the whole synchronization peak (85% sample in range 5-15 ms; mode between 6.1 and 8.0 ms (31% of sample], units fired between 8 and 485% times more often than would have been expected had the units been firing independently of one another. Amplitudes of the peak of the recorded histograms expressed as a proportion of control ranged from 1.8 to 10.9 (mean 3.9; bin width 160 microseconds). 5. The strength of synchronization between the firing of motor unit pairs was inversely related to differences in recruitment threshold. The largest amount of synchronization was observed for pairs of units in which both had recruitment thresholds less than 0.5 N or greater than 1.0 N. Less synchronization was found between pairs of units in which one had a recruitment threshold less than 0.05 N and the other a threshold greater than 1.0 N. 6. The time course of synchronization was well matched by the predictions of a theoretical model based on the hypothesis that underlying the observed synchronization is the joint arrival of EPSPs from branched last-order input fibres.

Several rodent models of obesity have been shown to develop excessive adiposity only when voluntary cage ambulation is restricted. We have previously shown that mice lacking the sarco(endo)plasmic reticulum Ca(2+)-ATPase pump regulatory protein sarcolipin (Sln(-/-)), an uncoupler of Ca(2+) uptake, develop excessive diet-induced obesity under standard housing conditions. However, it is unclear whether this phenotype is due, in part, to the sedentary housing environment in which these animals are kept. To address this, we allowed wild-type and Sln(-/-) animals ad libitum access to voluntary wheel running while consuming a standard chow or high-fat diet for 8 weeks. During this period, wheel revolutions were monitored along with weekly mass gain. Postdiet glucose tolerance and visceral adiposity were also taken. The volume of wheel running completed was similar between genotype, regardless of diet. Although voluntary activity reduced mass gain relative to sedentary controls within each diet (P < 0.05), visceral adiposity was surprisingly unaltered with activity. However, Sln(-/-) mice developed excessive obesity (P < 0.05) and glucose intolerance (P < 0.05) with high-fat feeding relative to wild-type controls. These findings indicate that the excessive diet-induced obese phenotype previously observed in Sln(-/-) mice is not the result of severely restricted daily ambulation, but in fact the inability to recruit uncoupling of the Ca(2+)-ATPase pump.

Study explores relationship between age (and sex and race) and acceptance of euthanasia. Women and non-Whites were less accepting because of religiosity. Among older people less acceptance was attributable to their lesser education and greater religiosity. Results suggest that quality of life in old age affects acceptability of euthanasia. (Author)

During fatiguing upper limb exercise, maintained firing of group III/IV muscle afferents can limit voluntary drive to muscles within the same limb. It is not known if this effect occurs in the lower limb. We investigated the effects of group III/IV muscle afferent firing from fatigued ipsilateral and contralateral extensor muscles and ipsilateral flexor muscles of the knee on voluntary activation of the knee extensors. In three experiments, we examined voluntary activation of the knee extensors by measuring changes in superimposed twitches evoked by femoral nerve stimulation. Subjects attended on 2 days for each experiment. On one day a sphygmomanometer cuff occluded blood flow of the fatigued muscles to maintain firing of group III/IV muscle afferents. After a 2-min extensor contraction (experiment 1; n = 9), mean voluntary activation was lower with than without maintained ischemia (47 ± 19% vs. 87 ± 8%, respectively; P < 0.001). After a 2-min knee flexor maximal voluntary contraction (MVC) (experiment 2; n = 8), mean voluntary activation was also lower with than without ischemia (59 ± 21% vs. 79 ± 9%; P < 0.01). After the contralateral (left) MVC (experiment 3; n = 8), mean voluntary activation of the right leg was similar with or without ischemia (92 ± 6% vs. 93 ± 4%; P = 0.65). After fatiguing exercise, activity in group III/IV muscle afferents reduces voluntary activation of the fatigued muscle and nonfatigued antagonist muscles in the same leg. However, group III/IV muscle afferents from the fatigued left leg had no effect on the unfatigued right leg. This suggests that any "crossover" of central fatigue in the lower limbs is not mediated by group III/IV muscle afferents.

Discussion about euthanasia is often confused because of a failure to distinguish between deliberate death acceleration and letting nature take its course. There is a need to reiterate the traditional principles upon which the care of the dying should be based, including the need for the doctor to practise medicine in the knowledge that eventually all his patients will die. It follows that a doctor does not have a duty to preserve life at all costs. The care of the patient with far-advanced cancer has improved considerably in many areas as a result of the establishment of hospices and domiciliary support teams. Treating the patient as a person is the key to a successful doctor-patient relationship. An analytical approach is necessary to control pain and other symptoms. Care of the relatives is also fundamental. Voluntary euthanasia and 'assisted suicide' represent an extreme solution to a situation which demands a far more comprehensive and compassionate approach. The need is not for a change in the law but for a change of emphasis in medical education. PMID:7108913

The suggestion by Phillips and Petrofsky (1980) and Wickiewicz et al. (1984) that artificial activation of the knee extensor muscles should result in greater relative changes in torque than those evident with maximal voluntary activation is examined by investigating the speed-torque relationship of the right knee extensor muscle group in eight human subjects in whom activation was achieved by 'maximal' voluntary effort or by electrical stimulation. Torque was measured at a specific knee angle during isokinetic concentric or eccentric actions at velocities between 0.17 and 3.66 rad/s and during isometric actions. It is shown that, with artificial activation, the relative changes in both eccentric and concentric torque were greater as the speed increased; the speed-torque relationship was independed of the extent of activation and was similar to that of an isolated muscle. On the other hand, activation by the central nervous system during maximal effort depended on the speed and the type of muscle action performed.

The purpose of this study was to evaluate the effects of early-life exercise on adult physical activity (wheel running, home-cage activity), body mass, food consumption, and circulating leptin levels in males from four replicate lines of mice selectively bred for high voluntary wheel running (High Runner or HR) and their four non-selected control (C) lines. Half of the mice were given wheel access shortly after weaning for three consecutive weeks. Wheel access was then removed for 52 days, followed by two weeks of adult wheel access for all mice. A blood sample taken prior to adult wheel testing was analyzed for circulating leptin concentration. Early-life wheel access significantly increased adult voluntary exercise on wheels during the first week of the second period of wheel access, for both HR and C mice, and HR ran more than C mice. During this same time period, activity in the home cages was not affected by early-age wheel access, and did not differ statistically between HR and C mice. Throughout the study, all mice with early wheel access had lower body masses than their sedentary counterparts, and HR mice had lower body masses than C mice. With wheel access, HR mice also ate significantly more than C mice. Early-life wheel access increased plasma leptin levels (adjusted statistically for fat-pad mass as a covariate) in C mice, but decreased them in HR mice. At sacrifice, early-life exercise had no statistically significant effects on visceral fat pad, heart (ventricle), liver or spleen masses (all adjusted statistically for variation in body mass). Results support the hypothesis that early-age exercise in mice can have at least transitory positive effects on adult levels of voluntary exercise, in addition to reducing body mass, and may be relevant for the public policy debates concerning the importance of physical education for children.

Abstract Physical activity can attenuate neuronal loss, reduce neuroinflammation, and facilitate recovery after brain injury. However, little is known about the mechanisms of exercise-induced neuroprotection after traumatic brain injury (TBI) or its modulation of post-traumatic neuronal cell death. Voluntary exercise, using a running wheel, was conducted for 4 weeks immediately preceding (preconditioning) moderate-level controlled cortical impact (CCI), a well-established experimental TBI model in mice. Compared to nonexercised controls, exercise preconditioning (pre-exercise) improved recovery of sensorimotor performance in the beam walk task, as well as cognitive/affective functions in the Morris water maze, novel object recognition, and tail-suspension tests. Further, pre-exercise reduced lesion size, attenuated neuronal loss in the hippocampus, cortex, and thalamus, and decreased microglial activation in the cortex. In addition, exercise preconditioning activated the brain-derived neurotrophic factor pathway before trauma and amplified the injury-dependent increase in heat shock protein 70 expression, thus attenuating key apoptotic pathways. The latter include reduction in CCI-induced up-regulation of proapoptotic B-cell lymphoma 2 (Bcl-2)-homology 3–only Bcl-2 family molecules (Bid, Puma), decreased mitochondria permeabilization with attenuated release of cytochrome c and apoptosis-inducing factor (AIF), reduced AIF translocation to the nucleus, and attenuated caspase activation. Given these neuroprotective actions, voluntary physical exercise may serve to limit the consequences of TBI. PMID:25419789

A substantial majority of Canadians favours a change to the Criminal Code which would make it legally permissible, subject to careful regulation, for patients suffering from incurable physical illness to opt for either physician assisted suicide (PAS) or voluntary active euthanasia (VAE). This discussion will focus primarily on the arguments for and against decriminalizing physician assisted suicide, with special reference to the British Columbia case of Lee Carter vs. Attorney General of Canada. The aim is to critique the arguments and at the same time to describe the contours of the current Canadian debate. Both ethical and legal issues raised by PAS are clarified. Empirical evidence available from jurisdictions which have followed the regulatory route is presented and its relevance to the slippery slope argument is considered. The arguments presented by both sides are critically assessed. The conclusion suggested is that evidence of harms to vulnerable individuals or to society, consequent upon legalization, is insufficient to support continued denial of freedom to those competent adults who seek physician assistance in hastening their death.

Activating flexor reflexes by electrical stimulation has been used as a mechanism to initiate the swing phase or to enhance it for spinal cord injured patients. However, it is necessary to know their contraction dynamics in order to artificially induce them at the right moment of a walking cycle. This requires understanding the temporal activation pattern of both surface and deep muscles simultaneously. This study aimed at developing a system to measure and analyze the temporal activation of both surface and deep muscles during voluntary contraction and flexor reflexes (also called withdrawal reflexes) using ultrasound imaging. A set of experiments were done to verify the validity of the system, while exploring the temporal pattern of muscle activation during flexor reflexes. As a result, we were able to quantify the surface and deep muscle activity by measuring the muscle thickness, pennation angle and long-axis displacement, from the ultrasound images.
People ascribe "euthanasia" different values and view it differently. This study hypothesized that a different framing of objectively the same euthanasia situations would affect people's attitudes toward it. Indeed, "positive" framing of euthanasia as not prolonging life resulted in more support for both passive and active euthanasia relative to "negative" framing of the objectively same situations as ending life. Two experiments replicated this pattern using either continuous measures of attitude or dichotomous measures of choice. The article offers two theoretical explanations for the effect of message framing on attitudes toward euthanasia, discusses implications of this effect, and suggests future research.

Voluntary activation levels during lengthening, isometric, and shortening contractions (angular velocity 60 degrees/s) were investigated by using electrical stimulation of the femoral nerve (triplet, 300 Hz) superimposed on maximal efforts. Recruitment of fiber populations was investigated by using the phosphocreatine-to-creatine ratio (PCr/Cr) of single characterized muscle fibers obtained from needle biopsies at rest and immediately after a series of 10 lengthening, isometric, and shortening contractions (1 s on/1 s off). Maximal voluntary torque was significantly higher during lengthening (270 +/- 55 N.m) compared with shortening contractions (199 +/- 47 N.m, P < 0.05) but was not different from isometric contractions (252 +/- 47 N.m). Isometric torque was higher than torque during shortening (P < 0.05). Voluntary activation level during maximal attempted lengthening contractions (79 +/- 8%) was significantly lower compared with isometric (93 +/- 5%) and shortening contractions (92 +/- 3%, P < 0.05). Mean PCr/Cr values of all fibers from all subjects at rest were 2.5 +/- 0.6, 2.0 +/- 0.7, and 2.0 +/- 0.7, respectively, for type I, IIa, and IIax fibers. After 10 contractions, the mean PCr/Cr values for grouped fiber populations (regardless of fiber type) were all significantly different from rest (1.3 +/- 0.2, 0.7 +/- 0.3, and 0.8 +/- 0.6 for lengthening, isometric, and shortening contractions, respectively; P < 0.05). The cumulative distributions of individual fiber populations after either contraction mode were significantly different from rest (P < 0.05). Curves after lengthening contractions were less shifted compared with curves from isometric and shortening contractions (P < 0.05), with a smaller shift for the type IIax compared with type I fibers in the lengthening contractions. The results indicate a reduced voluntary drive during lengthening contractions. PCr/Cr values of single fibers indicated a hierarchical order of recruitment of all fiber
The Belgian law relative to euthanasia has been published in 2002. A physician is allowed to help a patient with intractable suffering (physical or psychological). Legal conditions are clear. However, nothing is said about medical procedures or medications to be used. The present paper will present specific clinical situations at the end of life, practical procedures and medications. A special focus is made on psychological impact of euthanasia.

Muscle spindles provide critical information about movement position and velocity. They have been shown to act as stretch receptors in passive muscle, however, during active movements their behavior is less clear. In particular, spindle responses have been shown to be out-of-phase or phase advanced with respect to their expected muscle length-sensitivity. Whether this apparent discrepancy of spindle responses between passive and active movements is due to fusimotor (γ-drive) remains unresolved, since the activity of fusimotor neurons during voluntary non-locomotor movements are largely unknown. We developed a computational model to predict fusimotor activity and to investigate whether fusimotor activity could explain the empirically observed phase advance of spindle responses. The model links a biomechanical wrist model to length- and γ-drive-dependent transfer functions of type Ia and type II muscle spindle activity. Our simulations of two wrist-movement tasks suggest that (i) experimentally observed type Ia and type II activity profiles can to a large part be explained by appropriate, i.e. strongly modulated and task-dependent, γ-drive. That (ii) the empirically observed phase advance of type Ia or of type II profiles during active movement can be similarly explained by appropriate γ-drive. In summary, the simulation predicts that a highly task-modulated activation of the γ-system is instrumental in producing a large part of the empirically observed muscle spindle activity for voluntary wrist movements.

Although spasticity is a common symptom in children with cerebral palsy, weakness may be a much greater contributor to disability. We explore whether a treatment that reduces spasticity may also have potential benefit for improving strength. Ten children with cerebral palsy and spasticity in the ankle plantar flexor muscles were treated with oral baclofen for 4 weeks. We tested voluntary ability to activate ankle plantar flexor muscles using the ratio of the surface electromyographic signal during isometric maximal voluntary contraction to the M-wave during supramaximal electrical stimulation of the tibial nerve and tested muscle strength using maximal isometric plantar flexion torque. Mean maximal voluntary neuromuscular activation increased from 1.13 +/- 1.02 to 1.60 +/- 1.30 ( P < .05) after treatment, corresponding to an increase in 9 of 10 subjects. Mean maximal plantar flexion torque did not change. We conjecture that antispasticity agents could facilitate strength training by increasing the ability to voluntarily activate muscle.

During strong voluntary contractions, activity is not restricted to the target muscles. Other muscles, including contralateral muscles, often contract. We used transcranial magnetic stimulation (TMS) to analyse the origin of these unintended contralateral contractions (termed "associated" contractions). Subjects (n = 9) performed maximal voluntary contractions (MVCs) with their right elbow-flexor muscles followed by submaximal contractions with their left elbow flexors. Electromyographic activity (EMG) during the submaximal contractions was matched to the associated EMG in the left biceps brachii during the right MVC. During contractions, TMS was delivered to the motor cortex of the right or left hemisphere and excitatory motor evoked potentials (MEPs) and inhibitory (silent period) responses recorded from left biceps. Changes at a spinal level were investigated using cervicomedullary stimulation to activate corticospinal paths (n = 5). Stimulation of the right hemisphere produced silent periods of comparable duration in associated and voluntary contractions (218 vs 217 ms, respectively), whereas left hemisphere stimulation caused a depression of EMG but no EMG silence in either contraction. Despite matched EMG, MEPs elicited by right hemisphere stimulation were approximately 1.5-2.5 times larger during associated compared to voluntary contractions (P < 0.005). Similar inhibition of the associated and matched voluntary activity during the silent period suggests that associated activity comes from the contralateral hemisphere and that motor areas in this (right) hemisphere are activated concomitantly with the motor areas in the left hemisphere. Comparison of the MEPs and subcortically evoked potentials implies that cortical excitability was greater in associated contractions than in the matched voluntary efforts.

Despite maximal voluntary effort, the output of human motoneurone pools diminishes during fatigue. To assess motoneurone behaviour, we measured recurrent discharges evoked antidromically by supramaximal nerve stimulation after isometric maximal voluntary contractions (MVCs).They were measured as F-waves in the electromyographic activity (EMG). Supramaximal stimuli to the common peroneal and ulnar nerves evoked F-waves at rest before and after MVCs in tibialis anterior (TA) and abductor digit minimi (ADM), respectively. F-waves were depressed immediately after a sustained MVC. For TA, the size and time course of depression of the F-wave area (26 ± 13%; mean ± SD; P =0.007) and persistence (∼20%) were similar after a 10-s or 1-min MVC. For ADM, the decline in F-wave area (39.8 ± 19.6%; P <0.01) was similar after the two contractions but the decline in persistence (probability of occurrence) of the F-wave differed (14.6 ± 10.5% and 32.5 ± 17.1% after 10-s and 1-min MVCs respectively). Comparison of a very long (2-min) with a very short (2-s)MVC in ADM showed that the depression of F-wave area, as well as persistence, was greater after the longer contraction. This suggests, at least for ADM, that the depression is related to the duration of voluntary activity and that the decrease in F-waves could contribute to central fatigue. To examine whether changes in motor axon excitability caused the depression, we measured compound muscle action potentials (M-waves) to submaximal stimulation of the ulnar nerve after a 2-s and 2-min MVC. Submaximal M-waves were not depressed after a 2-s MVC. They were depressed by a 2-min MVC, but the time course of depression of the F- and M-waves differed. Thus, depression of F-waves does not simply reflect reduced excitability of peripheral motor axons.Hence, we propose that activity-dependent changes at the soma or the initial segment depress the recurrent discharge of human motoneurones and that this may contribute to central

The objective of this study was to investigate whether increased dietary water content and feeding frequency increased voluntary physical activity of young, lean adult female cats. A replicated 4 × 4 Latin square design with a 2 × 2 factorial treatment arrangement (feeding frequency and water content) was used. The 4 treatments consisted of 1 meal daily dry pet food without added water (1D; 12% moisture as is), 1 meal daily dry pet food with added water (1W; 70% total water content), 4 meals daily dry pet food without added water (4D; 12% moisture as is), and 4 meals daily dry pet food with added water (4W; 70% total water content). Eight healthy adult, lean, intact, young, female domestic shorthair cats were used in this experiment. Voluntary physical activity was evaluated using Actical activity monitors placed on collars and worn around the cats' necks for the last 7 d of each experimental period of 14 d. Food anticipatory activity (FAA) was calculated based on 2 h prior to feeding periods and expressed as a percentage of total daily voluntary physical activity. Increased feeding frequency (4 vs. 1 meal daily) resulted in greater average daily activity (P = 0.0147), activity during the light period (P = 0.0023), and light:dark activity ratio (P = 0.0002). In contrast, physical activity during the dark period was not altered by feeding frequency (P > 0.05). Cats fed 4 meals daily had increased afternoon FAA (P= 0.0029) compared with cats fed once daily. Dietary water content did not affect any measure of voluntary physical activity. Increased feeding frequency is an effective strategy to increase the voluntary physical activity of cats. Thus, it may assist in the prevention and management of obesity.

Those who campaign for law reform to permit "euthanasia" may seek different things and at least some of what they seek may already be permissible under the criminal law of England and Wales. In this paper I examine one means whereby the criminal law delivers outcomes acceptable to the euthanasia lobby, that is the curious notion of "causation" deployed by the law, which adds a value override to the more usual notion of factual causation such that, for example, if medical treatment falls within the acceptable range as normal and proper, the pre-existing injury or illness is treated as exclusively the cause of death and the doctor escapes criminal liability, even where the medical treatment will shorten life to the certain knowledge, possibly even the wish, of the doctor. Thus the law may already be delivering a range of outcomes--euthanasia in a weak sense--acceptable to the euthanasia lobby. If so, it achieves this by stealth. That is inappropriate to the doctor-patient relationship, which is one of trust. So there is a strong case for greater transparency. Moreover, there are limits to the acceptable outcomes which an unreformed criminal law can deliver and in a range of cases the criminal law condemns the doctor to impotence and the patient to a prolonged, miserable and undignified death. So there is also a case for going beyond the current law and legalising euthanasia in a strong sense.

This study investigated factors influencing ongoing participation in employee development activities. A multiple-indicator structural equation model building on the theory of planned behavior and prior employee development literature was tested with a survey across 4 organizations on 2 occasions. The model uses reactions to past participation and past supportiveness of the social and organizational environment as indirect antecedents of participation, filtered through their impact on attitudes and behavioral intentions toward future participation. Learning goal orientation also influenced attitudes toward participation. Whereas personal control over participation and higher levels of voluntariness were negatively related to participation, intentions to participate and availability of opportunities arose as strong predictors of higher participation rates. Many significant hypothesized paths were found, and 85% of the variance in participation was explained by the model variables. Increasing employee awareness of opportunities and managing positive attitudes toward those opportunities are recommended as key factors for increasing participation rates.

Platelet monoamine oxidase B (MAO-B) has been proposed to be a biological marker for the properties of monoamine systems, with low activity being associated with vulnerability for high scores on personality traits such as sensation seeking, monotony avoidance, and impulsiveness, as well as for vulnerability for alcoholism. In the present study, platelet MAO-B activity was analysed in 78 rhesus macaques, and its relation to voluntary alcohol intake and behaviours after intravenous alcohol administration was observed. Monkeys with low platelet MAO-B activity had low levels of 5-hydroxyindole acetic acid in cerebrospinal fluid and showed excessive aggression after alcohol administration. A novel finding was that animals with low platelet MAO-B activity showed less intoxication following alcohol administration. As we have shown previously, they also voluntarily consumed more alcohol. We here replicate results from studies on both humans and non-human primates, showing the utility of platelet MAO as a marker for risk behaviours and alcohol abuse. Furthermore, we link platelet MAO activity to alcohol sensitivity.

The pronators and supinators play a key role in the medio-lateral stability of the ankle joint complex (i.e. talo-crural and subtalar joints). We hypothesized that each shank muscle has a specific activation pattern determined by its anatomical course around the axes of the subtalar and talo-crural joints. A secondary objective was to examine the effect of foot posture on these activation patterns. Forty-nine young adults (25 normal-arched feet, 24 flat-arched feet) performed maximum voluntary isometric contractions against manual resistance in four movement directions: plantarflexion (PF), dorsiflexion (DF), pronation (PRO) and supination (SUP). Electromyographic activity was recorded from tibialis posterior (TP) and peroneus longus (PL) with intramuscular electrodes, and gastrocnemius medialis (GM) and tibialis anterior (TA) with surface electrodes. When compared to their agonist function, all muscles were co-activated at significantly lower levels in their synergistic function (GM: 23% during SUP, TA: 72% during SUP; TP: 42% during PF, PL: 52% during PF) (p<0.001). A significant interaction between foot posture and contraction type was evident for TA. During isometric contractions, the electromyographic activity of the shank muscles is geared to their biomechanical advantage according to their position relative to the subtalar and talo-crural joint axes.

Euthanasia and physician assisted-suicide are terms used to describe the process in which a doctor of a sick or disabled individual engages in an activity which directly or indirectly leads to their death. This behavior is engaged by the healthcare provider based on their humanistic desire to end suffering and pain. The psychiatrist's involvement may be requested in several distinct situations including evaluation of patient capacity when an appeal for euthanasia is requested on grounds of terminal somatic illness or when the patient is requesting euthanasia due to mental suffering. We compare attitudes of 49 psychiatrists towards euthanasia and assisted suicide with a group of 54 other physicians by means of a questionnaire describing different patients, who either requested physician-assisted suicide or in whom euthanasia as a treatment option was considered, followed by a set of questions relating to euthanasia implementation. When controlled for religious practice, psychiatrists expressed more conservative views regarding euthanasia than did physicians from other medical specialties. Similarly female physicians and orthodox physicians indicated more conservative views. Differences may be due to factors inherent in subspecialty education. We suggest that in light of the unique complexity and context of patient euthanasia requests, based on their training and professional expertise psychiatrists are well suited to take a prominent role in evaluating such requests to die and making a decision as to the relative importance of competing variables.

This study examined whether central fatigue was exacerbated by an increase in muscle contractile speed caused by passive hyperthermia (PaH) and whether exercise-induced hyperthermia (ExH) combined with related peripheral fatigue influenced this response. The ExH was induced by cycling at 60% of maximal oxygen uptake in 38°C conditions and the PaH by sitting in a 48°C climate chamber. Ten men performed brief (≈ 5 s) and sustained (30 s) maximal voluntary isometric contractions (MVCs) of the knee extensors at baseline (CON, ∼37.1°C) and during moderate (MOD, ≈ 38.5°C) and severe (SEV, ∼39.5°C) hyperthermia. Motor nerve and transcranial magnetic stimulation were used to assess voluntary muscle and cortical activation level, along with contractile properties. Brief MVC force decreased to a similar extent during SEV-ExH (-8%) and SEV-PaH (-6%; P < 0.05 versus CON). Sustained MVC force also decreased during MOD-ExH (-10%), SEV-ExH (-13%) and SEV-PaH (-7%; P < 0.01 versus CON). Motor nerve and cortical activation were reduced on reaching MOD (≈ 3%) and SEV (≈ 5%) ExH and PaH during the brief and sustained MVCs (P < 0.01 versus CON). Peak twitch force decreased on reaching SEV-ExH and SEV-PaH (P < 0.05 versus CON). Following transcranial magnetic stimulation, during the brief and sustained MVCs the peak muscle relaxation rate increased in ExH and PaH (P < 0.01 versus CON). The increase was greatest during the sustained contraction in SEV-PaH (P < 0.01), but this did not exacerbate central fatigue relative to ExH. These results indicate that during fatiguing cycling exercise in the heat, quadriceps peak relaxation rate increases. However, the centrally mediated rate of activation appears sufficient to overcome even the largest increase in muscle relaxation rate, seen during SEV-PaH.

An agent who takes his own life acts in violation of the moral law, according to Kant; suicide, and, by extension, assisted suicide are therefore wrong. By a similar argument, and with a few important exceptions, killing is wrong; implicitly, then, voluntary euthanasia is also wrong. Kant's conclusions are uncompelling and his argument in these matters is undermined on considering other areas of his thought. Kant, in forbidding suicide and euthanasia, is conflating respect for persons and respect for people, and assuming that, in killing a person (either oneself or another), we are thereby undermining personhood. But an argument along these lines is faulty according to Kant's own standards. There is no reason why Kantians have to accept that self‐killing and euthanasia are contrary to the moral law. Even if some Kantians adhere to this doctrine, others can reject it. PMID:17012496

This article maps the concept of 'good death' (euthanasia) in the ancient world and explores the marginal role of the doctor at a 'good dying'. His assistance was not needed when the Homeric warrior died as a hero and was expected to accept death with resignation. Later the city-state regarded as heroes the men fallen for the cause of the community, honouring these model citizens as those who died well. In the more individualistic age of Hellenism and the Roman Empire, a death in luxury or without suffering could be styled euthanasia. The doctor had neither a place in those acts of dying nor in cases of natural death. He shunned death as a failure of his art. Sometimes a doctor was called in to assist in voluntary death, a role that was not forbidden by the Hippocratic oath. An appeal to this oath by opponents of euthanasia in the modern sense of the word therefore is mistaken.

Background Euthanasia remains a controversial topic in both public discourses and legislation. Although some determinants of acceptance of euthanasia and physician-assisted death have been identified in previous studies, there is still a shortage of information whether different forms of euthanasia are supported by the same or different sub-populations and whether authoritarian personality dispositions are linked to attitudes towards euthanasia. Methods A large, representative face-to-face survey was conducted in Austria in 2014 (n = 1,971). Respondents faced three scenarios of euthanasia and one of physician assisted death differing regarding the level of specificity, voluntariness and subject, requiring either approval or rejection: (1) abstract description of euthanasia, (2) abstract description of physician-assisted suicide, (3) the case of euthanasia of a terminally-ill 79-year old cancer patient, and (4) the case of non-voluntary, physician assisted death of a severely disabled or ill neonate. A number of potential determinants for rejection ordered in three categories (socio-demographic, personal experience, orientations) including authoritarianism were tested via multiple logistic regression analyses. Results Rejection was highest in the case of the neonate (69%) and lowest for the case of the older cancer patient (35%). A consistent negative impact of religiosity on the acceptance across all scenarios and differential effects for socio-economic status, area of residence, religious confession, liberalism, and authoritarianism were found. Individuals with a stronger authoritarian personality disposition were more likely to reject physician-assisted suicide for adults but at the same time also more likely to approve of physician-assisted death of a disabled neonate. Conclusion Euthanasia in adults was supported by a partially different sub-population than assisted death of disabled neonates. PMID:25906265

The main purposes of the present study were to see how the term “euthanasia” influences people’s support for or opposition to euthanasia; and to see how euthanasia attitude relates to religious orientation and personality factors. In this study two different euthanasia attitude scales were compared. 197 students were selected to fill out either the Euthanasia Attitude Scale (EAS) or Wasserman’s Attitude Towards Euthanasia scale (ATE scale). The former scale includes the term “euthanasia”, the latter does not. All participants filled out 50 items of International Personality Item Pool, 16 items of the the HEXACO openness, and 14 items of Religious Orientation Scale-Revised. Results indicated that even though the two groups were not different in terms of gender, age, education, religiosity and personality, mean score on the ATE scale was significantly higher than that of the EAS. Euthanasia attitude was negatively correlated with religiosity and conscientiousness and it was positively correlated with psychoticism and openness. It can be concluded that analyzing the attitude towards euthanasia with the use of EAS rather than the ATE scale results in lower levels of opposition against euthanasia. This study raises the question of whether euthanasia attitude scales should contain definitions and concepts of euthanasia or they should describe cases of it. PMID:23908751

A ratio between the torque generated by maximal voluntary isometric contraction (MVIC) and exogenous electrical stimulus, central activation ratio (CAR), has been widely used to assess quadriceps function. To date, no data exist regarding between-session reliability of this measurement. Thirteen neurologically sound volunteers underwent three testing sessions (three trials per session) with 48 hours between-session. Subjects performed MVICs of the quadriceps with the knee locked at 90° flexion and the hip at 85°. Once the MVIC reached a plateau, an electrical stimulation from superimposed burst technique (SIB: 125 V with peak output current 450 mA) was manually delivered and transmitted directly to the quadriceps via stimulating electrodes. CAR was calculated by using the following equation: CAR = MVIC torque/MVIC + SIB torque. Intraclass correlation coefficients (ICC) were calculated within- (ICC((2,1))) and between-session (ICC((2,k))) for MVIC torques and CAR values. Our data show that quadriceps MVIC and CAR are very reliable both within- (ICC((2,1)) = 0.99 for MVIC; 0.94 for CAR) and between-measurement sessions (ICC((2,k)) = 0.92 for MVIC; 0.86 for CAR) in healthy young adults. For clinical research, more data of the patients with pathological conditions are required to ensure reproducibility of calculation of CAR.

Background: Deep brain stimulation (DBS) is an emerging treatment strategy for severe, medication-refractory Tourette syndrome (TS). Thalamic (Cm-Pf) and pallidal (including globus pallidus interna, GPi) targets have been the most investigated. While the neurophysiological correlates of Parkinson's disease (PD) in the GPi and subthalamic nucleus (STN) are increasingly recognized, these patterns are not well characterized in other disease states. Recent findings indicate that the cross-frequency coupling (CFC) between beta band and high frequency oscillations (HFOs) within the STN in PD patients is pathologic. Methods: We recorded intraoperative local field potentials (LFPs) from the postero-ventrolateral GPi in three adult patients with TS at rest, during voluntary movements, and during tic activity and compared them to the intraoperative GPi-LFP activity recorded from four unmedicated PD patients at rest. Results: In all PD patients, we noted excessive beta band activity (13–30 Hz) at rest which consistently modulated the amplitude of the co-existent HFOs observed between 200 and 400 Hz, indicating the presence of beta-HFO CFC. In all 3TS patients at rest, we observed theta band activity (4–7 Hz) and HFOs. Two patients had beta band activity, though at lower power than theta oscillations. Tic activity was associated with increased high frequency (200–400 Hz) and gamma band (35–200 Hz) activity. There was no beta-HFO CFC in TS patients at rest. However, CFC between the phase of 5–10 Hz band activity and the amplitude of HFOs was found in two TS patients. During tics, this shifted to CFC between the phase of beta band activity and the amplitude of HFOs in all subjects. Conclusions: To our knowledge this is the first study that shows that beta-HFO CFC exists in the GPi of TS patients during tics and at rest in PD patients, and suggests that this pattern might be specific to pathologic/involuntary movements. Furthermore, our findings suggest that during tics

Physician-assisted suicide (PAS) is a controversial subject which has recently captured the interest of media, public, politicians, and medical profession. Although active euthanasia and PAS are illegal in most parts of the world, with the exception of Switzerland and the Netherlands, there is pressure from some politicians and patient support groups to legalize this practice in and around Europe that could possibly affect many parts of the world. The legal status of PAS and euthanasia in India lies in the Indian Penal Code, which deals with the issues of euthanasia, both active and passive, and also PAS. According to Penal Code 1860, active euthanasia is an offence under Section 302 (punishment for murder) or at least under Section 304 (punishment for culpable homicide not amounting to murder). The difference between euthanasia and physician assisted death lies in who administers the lethal dose; in euthanasia, this is done by a doctor or by a third person, whereas in physician-assisted death, this is done by the patient himself. Various religions and their aspects on suicide, PAS, and euthanasia are discussed. People argue that hospitals do not pay attention to patients' wishes, especially when they are suffering from terminally ill, crippling, and non-responding medical conditions. This is bound to change with the new laws, which might be implemented if PAS is legalized. This issue is becoming relevant to psychiatrists as they need to deal with mental capacity issues all the time.

This cross-sectional, observational study was undertaken to examine whether voluntary activation failure could contribute to the persisting weakness observed in some patients with treated idiopathic inflammatory myositis. In 20 patients with myositis of more than six months' duration (5 males, 15 females; mean [± 1 SD] age 53  years) and 102 normal subjects (44 males, 58 females; mean age 32  years), isometric maximum voluntary contractions (MVCs) of the dominant quadriceps femoris (QF) were quantified. Absolute MVC results of normal subjects and patients were then normalised with respect to lean body mass (force per units of lean body mass), giving a result in Newtons per kilogram. Based on mass-normalised force data of normal subjects, patients were arbitrarily stratified into "weak" and "not weak" subgroups. During further MVC attempts, the "twitch interpolation" technique was used to assess whether the QF voluntary activation of patients was complete. This technique relies on the fact that, because muscle activation is incomplete during submaximal voluntary contractions, electrical stimulation of the muscle can induce force increments superimposed on the submaximal voluntary force being generated. No between-gender differences were seen in the mass-normalised MVC results of healthy subjects, so the gender-combined results of 6.6 (1.5) N/kg were used for patient stratification. No between-gender difference was found for mass-normalised MVCs in patients: males 5.4 (3.2) and females 3.0 (1.7) N/kg (p > 0.05). Mass-normalised MVCs of male patients were as great as those of normal subjects (p > 0.05), but mass-normalised MVCs of female patients were significantly smaller than those of the normal subjects (p < 0.001). Only one of the six "not weak" patients exhibited interpolated twitches during electrical stimulation, but six of the 14 "weak" patients did, the biggest twitches being seen in the weakest patient. That interpolated twitches can be induced in

In this paper, to clarify whether a firm's voluntary approach to environmental protection is beneficial for both the environment and business, we analyze whether a firm's voluntary implementation of an environmental management system (EMS) simultaneously reduces its environmental impacts and improves its productivity. Using data on Japanese manufacturing firms for 2002-2008, we find empirical support for the view that the implementation of an EMS simultaneously reduces environmental impacts and improves productivity, and that a reduction in environmental impacts also improves productivity. However, in the context of this relationship, the direct effect of implementing an EMS on productivity is conditional. If various other activities designed to improve productivity implemented in response to market discipline are also taken into account, the effect of implementing an EMS is hidden by the effects of these activities. This implies that voluntary environmental management activities are merely a minor component of these activities. Therefore, the relationship between the implementation of an EMS and productivity improvement is not strong, although implementing an EMS indirectly improves productivity by reducing environmental impacts.

Euthanasia provokes controversies in various domains, such as the moral, ethical, legal, religious, scientific, and economic. India legalised passive euthanasia (withdrawal of life support) for patients with brain death or who are in a permanent vegetative state in 2011, but research on perceptions of euthanasia among people in India is limited. This study aimed to examine nurses' perceptions of the practice of euthanasia as well as factors influencing those perceptions. A non-probability quantitative, cross-sectional design was adopted for a sample of 214 nurses working at a tertiary care centre. Data was collected through self-reported questionnaires at the nurses workplace.The findings revealed mixed opinions on euthanasia among the nurses. However, the majority of the participants did not agree with the practice of euthanasia. Nonetheless, further research is needed on this issue across the country among various health professionals in the context of current legislation.

Excessive or persistent proinflammatory cytokine production plays a central role in autoimmune diseases. Acute activation of the sympathetic nervous system attenuates the innate immune response. However, both the autonomic nervous system and innate immune system are regarded as systems that cannot be voluntarily influenced. Herein, we evaluated the effects of a training program on the autonomic nervous system and innate immune response. Healthy volunteers were randomized to either the intervention (n = 12) or control group (n = 12). Subjects in the intervention group were trained for 10 d in meditation (third eye meditation), breathing techniques (i.a., cyclic hyperventilation followed by breath retention), and exposure to cold (i.a., immersions in ice cold water). The control group was not trained. Subsequently, all subjects underwent experimental endotoxemia (i.v. administration of 2 ng/kg Escherichia coli endotoxin). In the intervention group, practicing the learned techniques resulted in intermittent respiratory alkalosis and hypoxia resulting in profoundly increased plasma epinephrine levels. In the intervention group, plasma levels of the anti-inflammatory cytokine IL-10 increased more rapidly after endotoxin administration, correlated strongly with preceding epinephrine levels, and were higher. Levels of proinflammatory mediators TNF-α, IL-6, and IL-8 were lower in the intervention group and correlated negatively with IL-10 levels. Finally, flu-like symptoms were lower in the intervention group. In conclusion, we demonstrate that voluntary activation of the sympathetic nervous system results in epinephrine release and subsequent suppression of the innate immune response in humans in vivo. These results could have important implications for the treatment of conditions associated with excessive or persistent inflammation, such as autoimmune diseases. PMID:24799686

The AVMA Panel on Euthanasia recommends that sensitive animals should not be present during the euthanasia of others, especially of their own species, but does not provide guidelines on how to identify a sensitive species. To determine if mice are a sensitive species we reviewed literature on empathy in mice, and measured the cardiovascular and activity response of mice observing euthanasia of conspecifics. We studied male 16-wk-old C57BL/6N mice and found no increase in cardiovascular parameters or activity in the response of the mice to observing CO2 euthanasia. Mice observing decapitation had an increase in all values, but this was paralleled by a similar increase during mock decapitations in which no animals were handled or euthanized. We conclude that CO2 euthanasia of mice does not have an impact on other mice in the room, and that euthanasia by decapitation likely only has an effect due to the noise of the guillotine. We support the conceptual idea that mice are both a sensitive species and display empathy, but under the controlled circumstances of the euthanasia procedures used in this study there was no signaling of stress to witnessing inhabitants in the room.

The outcome of the physician-assisted suicide and euthanasia debate will profoundly influence physicians' role in society, the kind of society we become, and the way physicians and patients relate to one another. Three forces account for the move to physician-assisted suicide and euthanasia: an abuse of scientific advancement, a new political philosophy, and the erosion of religious consensus. The relationship between patients and physicians has often been understood as a convenant with rights on patients' part and duties on physicians' part. Physicians' duties in this covenantal relationship are to act for patients' good (a positive duty) and to do no harm (a negative duty). Euthanasia and assisted suicide are morally wrong because, as the Judeo-Christian ethic teaches, human beings are creatures of God and have only stewardship, not dominion, over life. But in our pluralistic society, which seems to lack consensus on religion, on communal responsibility, and on common values, one cannot argue against mercy killing and assisted suicide on theological grounds. Our society generally agrees, however, that a discussion of values may take place in the language of moral philosophy, a language that expresses right reason.

Under German criminal law, euthanasia assisted by the attending physician involves the risk of criminal prosecution. However, in the absence of clear legal provisions, the law concerning euthanasia has been primarily developed by court rulings and jurisprudential literature in the last 30 years. According to a traditional classification there are four categories of euthanasia: help in the dying process, direct active euthanasia, indirect active euthanasia and passive euthanasia. However, there is still no generally accepted definition for the general term "euthanasia". The development of the law on the permissibility of euthanasia was strongly influenced by the conflict between the right of self-determination of every human being guaranteed by the Constitution and the constitutional mandate of the state to protect and maintain human life. The decisions of the German Federal Court of Justice on euthanasia in the criminal trials "Wittig" (1984), "Kempten" (1994) and "Putz" (2010) as well as the ruling of the 12th Division for Civil Matters of the Federal Court of Justice (2003) are of special importance. Some of these decisions were significantly influenced by the discussions in the jurisprudential literature. However, the German Bundestag became active for the first time as late as in 2009 when it adopted the 3rd Guardianship Amendment Act, which also contains provisions on the legal validity of a living will independent of the nature and stage of an illness. In spite of the new law, an analysis of the "Putz" case makes it especially clear that the criminal aspects of legal issues at the end of a person's life still remain controversial. It is to be expected that this issue will remain the subject of intensive discussion also in the next few years.

Performance in a behavioural task can be influenced by both bottom-up and top-down processes such as stimulus modality and prior probability. Here, we exploited differences in behavioural strategy to explore the role of the intermediate and deep layers of the superior colliculus (dSC) in covert orienting. Two monkeys were trained on a predictive cued-saccade task in which the cue predicted the target's upcoming location with 80% validity. When the delay between cue and target onset was 250 ms, both monkeys showed faster responses to the uncued (Invalid) location. This was associated with a reduced target-aligned response in the dSC on Valid trials for both monkeys and is consistent with a bottom-up (i.e. involuntary) bias. When the delay was increased to 650 ms, one monkey continued to show faster responses to the Invalid location whereas the other monkey showed faster responses to the Valid location, consistent with a top-down (i.e. voluntary) bias. This latter behaviour was correlated with an increase in activity in dSC neurons preceding target onset that was absent in the other monkey. Thus, using the information provided by the cue shifted the emphasis towards top-down processing, while ignoring this information allowed bottom-up processing to continue to dominate. Regardless of the selected strategy, however, neurons in the dSC consistently reflected the current bias between the two processes, emphasizing its role in both the bottom-up and top-down control of orienting behaviour.

A survey was conducted with 3021 employees of the Federal Government using self-administered questionnaires in order to collect data on the socioeconomic background of those surveyed (sex, age, civil status, number of children, religious, affiliation, educational level and monthly income), as well as their opinions about euthanasia. For the purposes of this study, three types of euthanasia were considered: 1) passive (the suspension of life support systems); 2) active (the application of immediate death causing means for people who suffer from incurable illnesses); and 3) active in the medium term (the application of substances which keep a patient sedated and comfortable while all food is withheld). Passive and medium-term active euthanasia were accepted by 40 percent of the population surveyed, while active euthanasia was accepted by 20 percent. These percentages were higher among young people, among those who were not heavily influenced by or did not practice religion, among professionals and among post-graduates.

Transcranial magnetic stimulation (TMS) of the motor cortex during voluntary contractions elicits electrophysiological and mechanical responses in the target muscle. The effect of different TMS intensities on exercise-induced changes in TMS-elicited variables is unknown, impairing data interpretation. This study aimed to investigate TMS intensity effects on maximal voluntary activation (VATMS), motor-evoked potentials (MEPs), and silent periods (SPs) in the quadriceps muscles before, during, and after exhaustive isometric exercise. Eleven subjects performed sets of ten 5-s submaximal isometric quadriceps contractions at 40% of maximal voluntary contraction (MVC) strength until task failure. Three different TMS intensities (I100, I75, I50) eliciting MEPs of 53 ± 6%, 38 ± 5% and 25 ± 3% of maximal compound action potential (Mmax) at 20% MVC were used. MEPs and SPs were assessed at both absolute (40% baseline MVC) and relative (50%, 75%, and 100% MVC) force levels. VATMS was assessed with I100 and I75. When measured at absolute force level, MEP/Mmax increased during exercise at I50, decreased at I100 and remained unchanged at I75. No TMS intensity effect was observed at relative force levels. At both absolute and relative force levels, SPs increased at I100 and remained stable at I75 and I50. VATMS assessed at I75 tended to be lower than at I100. TMS intensity affects exercise-induced changes in MEP/Mmax (only when measured at absolute force level), SPs, and VATMS. These results indicate a single TMS intensity assessing maximal voluntary activation and exercise-induced changes in corticomotoneuronal excitability/inhibition may be inappropriate.

The neuroanatomical and neurochemical basis of alcohol reward has been studied extensively, but global alterations of neural activity in reward circuits during chronic alcohol use remain poorly described. Here, we measured brain activity changes produced by long-term voluntary alcohol drinking in the alcohol-preferring AA (Alko alcohol) rats using manganese-enhanced magnetic resonance imaging (MEMRI). MEMRI is based on the ability of paramagnetic manganese ions to accumulate in excitable neurons and thereby enhance the T1-weighted signal in activated brain areas. Following 6 weeks of voluntary alcohol drinking, AA rats were allowed to drink alcohol for an additional week, during which they were administered manganese chloride (MnCl2 ) with subcutaneous osmotic minipumps before MEMRI. A second group with an identical alcohol drinking history received MnCl2 during the abstinence week following alcohol drinking. For comparing alcohol with a natural reinforcer, MEMRI was also performed in saccharin-drinking rats. A water-drinking group receiving MnCl2 served as a control. We found that alcohol drinking increased brain activity extensively in cortical and subcortical areas, including the mesocorticolimbic and nigrostriatal dopamine pathways and their afferents. Remarkably similar activation maps were seen after saccharin ingestion. Particularly in the prelimbic cortex, ventral hippocampus and subthalamic nucleus, activation persisted into early abstinence. These data show that voluntary alcohol recruits an extensive network that includes the ascending dopamine systems and their afferent connections, and that this network is largely shared with saccharin reward. The regions displaying persistent alterations after alcohol drinking could participate in brain networks underlying alcohol seeking and relapse.
The article examines current opinions toward euthanasia of persons with mental retardation in light of the history of public and professional attitudes. It also discusses the rejection of euthanasia on moral and religious grounds, and notes the use of lifelong incarceration, based on eugenics principles, to accomplish similar ends. (DB)
Proponents and opponents of euthanasia have argued passionately about whether it should be legalized. In Australia in the mid-1990s, following the world's first legal euthanasia deaths, Dr. Philip Nitschke initiated a different approach: a search for do-it-yourself technological means of dying with dignity. The Australian government has opposed…

Epidemiological studies of suicide in the elderly indicate that, in the last few decades, there has been a relevant increase in suicide rates in old age in a number of Asian and Latin nations, with an almost parallel decrease in Anglo-Saxon counties. Mental disorders, particularly depression, physical illness, personality traits such as hostility, hopelessness, the inability to verbally express psychological pain and dependency on others, recent life events and losses are all factors that may contribute to suicide in later life. Compared with suicide in other age groups, mors voluntaris in late life is associated with the use of highly lethal methods, less ambivalence and impulsivity, and more determination and intent to die. Accordingly, elderly suicidal individuals are more likely than younger subjects to complete rather than attempt suicide. Some evidence suggests also that the characteristics of elderly individuals who attempt suicide may not overlap with those who complete suicide. Death thoughts and suicidal ideations are relatively rare among mentally healthy elderly adults, and are less predominant in this age bracket. However, whether elderly suicidal behaviour exists along a continuum, progressing in severity from death thoughts and suicidal ideation to suicide attempts and completed suicide, remains unclear. Assisted suicide and euthanasia in the elderly have been associated with the desire to escape chronic physical pain and suffering caused by terminal illness, and to relieve mental anguish and feelings of hopelessness, depression and extreme "tiredness of life." The role of the family and those treating chronically ill members is crucial in the final stages of life, particularly when autonomy and the ability of the elderly individual to make end-of-life decisions are compromised. The main aspects associated with these controversial phenomena, particularly from a transcultural perspective, are reviewed in this article.
Since 2002, the Belgian legal framework authorizes the practice of euthanasia, under certain conditions. All cases have to be reported to the Assessment and Control Commission (ACC). To date, more than 6000 cases have been reported since 2002. To make a statement about the Belgian experience requires considering different points: data and evaluation from the ACC reports, their analysis, consequences on medical practice, legal and medical perspectives, critics and attacks about the legal framework, the concept of individual and institutional conscience clause. Regarding all these topics, we note that the Belgian experience is more than an example and shows that adequate answers may be provided to patients experiencing intolerable suffering.

Within developed nations, there is increasing public debate about and apparent endorsement of the appropriateness of euthanasia as an autonomous choice to die in the face of intolerable suffering. Surveys report socio-demographic differences in rates of acceptance of euthanasia, but there is little in-depth analysis of how euthanasia is understood and positioned within the social and moral lives of individuals, particularly those who might be considered suitable candidates-for example, terminally-ill cancer patients. During discussions with 28 such patients in Australia regarding medical decisions at the end of life, euthanasia was raised by 13 patients, with the others specifically asked about it. Twenty-four patients spoke positively of euthanasia, 19 of these voicing some concerns. None identified euthanasia as a currently favoured option. Four were completely against it. Endorsement for euthanasia was in the context of a hypothetical future or for a hypothetical other person, or temporally associated with acute pain. Arguments supporting euthanasia framed the issue as a matter of freedom of choice, as preserving dignity in death, and as curbing intolerable pain and suffering, both of the patient and of those around them. A common analogy featured was that of euthanising a dog. These arguments were typically presented as self-evident justification for euthanasia, construed as an appropriate choice to die, with opposers positioned as morally inferior or ignorant. The difficulties of ensuring 'choice' and the moral connotations of 'choosing to die,' however, worked to problematise the appropriateness of euthanising specific individuals. We recommend further empirical investigation of the moral and social meanings associated with euthanasia.

We examined the molecular and metabolomic effects of voluntary running wheel activity in late middle-aged male Sprague Dawley rats (16-17 months). Rats were assigned either continuous voluntary running wheel access for 8 weeks (RW+) or cage-matched without running wheel access (RW-). The 9 RW+ rats averaged 83 m/day (range: 8-163 m), yet exhibited both 84% reduced individual body weight gain (4.3 g vs. 26.3 g, P = 0.02) and 6.5% reduced individual average daily food intake (20.6 g vs. 22.0 g, P = 0.09) over the 8 weeks. Hindlimb muscles were harvested following an overnight fast. Muscle weights and myofiber cross-sectional area showed no difference between groups. Western blots of gastrocnemius muscle lysates with a panel of antibodies suggest that running wheel activity improved oxidative metabolism (53% increase in PGC1α, P = 0.03), increased autophagy (36% increase in LC3B-II/-I ratio, P = 0.03), and modulated growth signaling (26% increase in myostatin, P = 0.04). RW+ muscle also showed 43% increased glycogen phosphorylase expression (P = 0.04) and 45% increased glycogen content (P = 0.04). Metabolomic profiling of plantaris and soleus muscles indicated that even low-volume voluntary running wheel activity is associated with decreases in many long-chain fatty acids (e.g., palmitoleate, myristoleate, and eicosatrienoate) relative to RW- rats. Relative increases in acylcarnitines and acyl glycerophospholipids were also observed in RW+ plantaris. These data establish that even modest amounts of physical activity during late middle-age promote extensive metabolic remodeling of skeletal muscle.

Endocrine disrupting chemicals (EDC) have received considerable attention as potential obesogens. Past studies examining obesogenic potential of one widespread EDC, bisphenol A (BPA), have generally focused on metabolic and adipose tissue effects. However, physical inactivity has been proposed to be a leading cause of obesity. A paucity of studies has considered whether EDC, including BPA, affects this behavior. To test whether early exposure to BPA and ethinyl estradiol (EE, estrogen present in birth control pills) results in metabolic and such behavioral disruptions, California mice developmentally exposed to BPA and EE were tested as adults for energy expenditure (indirect calorimetry), body composition (echoMRI) and physical activity (measured by beam breaks and voluntary wheel running). Serum glucose and metabolic hormones were measured. No differences in body weight or food consumption were detected. BPA-exposed females exhibited greater variation in weight than females in control and EE groups. During the dark and light cycles, BPA females exhibited a higher average respiratory quotient than control females, indicative of metabolizing carbohydrates rather than fats. Various assessments of voluntary physical activity in the home cage confirmed that during the dark cycle, BPA and EE-exposed females were significantly less active in this setting than control females. Similar effects were not observed in BPA or EE-exposed males. No significant differences were detected in serum glucose, insulin, adiponectin and leptin concentrations. Results suggest that females developmentally exposed to BPA exhibit decreased motivation to engage in voluntary physical activity and altered metabolism of carbohydrates v. fats, which could have important health implications.

Several reasons have been suggested for the elevated risk of suicide experienced by those in the veterinary profession. The current study aimed to investigate possible links between veterinarians' attitudes to 'convenience' or non-justified animal euthanasia and attitudes towards human euthanasia and suicide. Veterinary students and graduates had a negative attitude towards convenience animal euthanasia, but their attitudes changed over time (pre-clinical studies, clinical studies and recently graduated). A greater tolerance to euthanasia was displayed in the later years of study and post qualification - primarily by males. Attitudes towards both human euthanasia and suicide, however, remained stable over time and indicated on average a neutral stance. No correlations were found between attitudes to convenience euthanasia and either human euthanasia or suicide, suggesting a tolerance to convenience euthanasia of animals does not lead to desensitisation in valuing human life and a changed attitude to human euthanasia or suicide, or vice versa. Attitudes to human euthanasia and suicide were predictably correlated, perhaps suggesting an overarching attitude towards control over human death. The results of the current study throw into question the argument that it is the changes in attitudes to animal life that affect veterinarian's attitudes to human life and contribute to the high suicide rate.

The level of sustainable excitability within lumbar spinal cord circuitries is one of the factors determining the functional outcome of locomotor therapy after motor-incomplete spinal cord injury. Here, we present initial data using noninvasive transcutaneous lumbar spinal cord stimulation (tSCS) to modulate this central state of excitability during voluntary treadmill stepping in three motor-incomplete spinal cord-injured individuals. Stimulation was applied at 30 Hz with an intensity that generated tingling sensations in the lower limb dermatomes, yet without producing muscle reflex activity. This stimulation changed muscle activation, gait kinematics, and the amount of manual assistance required from the therapists to maintain stepping with some interindividual differences. The effect on motor outputs during treadmill-stepping was essentially augmentative and step-phase dependent despite the invariant tonic stimulation. The most consistent modification was found in the gait kinematics, with the hip flexion during swing increased by 11.3° ± 5.6° across all subjects. This preliminary work suggests that tSCS provides for a background increase in activation of the lumbar spinal locomotor circuitry that has partially lost its descending drive. Voluntary inputs and step-related feedback build upon the stimulation-induced increased state of excitability in the generation of locomotor activity. Thus, tSCS essentially works as an electrical neuroprosthesis augmenting remaining motor control.

Voluntary runners are subjected to a massive increase in reactive oxygen/nitrogen species production, which can promote different oxidative stress-related diseases such as premature aging, neurodegenerative disorders, and cancer. The aims of this work were to evaluate the following in peripheral blood cells of voluntary runners: (i) DNA status; (ii) susceptibility to the in vitro insult induced by hydrogen peroxide (H(2)O(2)) as a breaking agent; (iii) capabilities of 3,5,4'-trihydroxystilbene (RESV) in counteracting DNA damage. Twenty-five male voluntary runners were compared with 20 sedentary men, as age-matched controls, and DNA status was evaluated with different versions of comet assay: alkaline, neutral, and Fpg enzyme-modified version to measure 8-OH-deoxyguanosine (8-oxo-dG) levels. The H(2)O(2) and/or RESV treatments were performed directly on agarose-embedded cells (atypical comet assay). The results evidenced DNA damage and levels of 8-oxo-dG higher in runners than in sedentary control subjects. The runners' DNA was more prone to the in vitro-induced oxidative insult (200 μM H(2)O(2)) than that of the control group. Resveratrol (100 μM), depending on the individual basal DNA status, was able to switch from antioxidant to pro-oxidant. Our results, on the one hand, validated the proposed in vitro experimental protocol in order to measure individual DNA status. On the other hand, our data point out the importance of monitoring the athletes' redox status before subjecting them to dietary supplementation treatment.

Attitudes toward euthanasia differ between individuals and populations, and in many studies the medical profession is more reluctant than the general public. Our goal was to explore medical students' attitude toward euthanasia. A questionnaire containing open-ended questions was answered anonymously by 165 first- and fifth-year medical students. Data were analysed using qualitative content analysis with no predetermined categories. The students' arguments opposing euthanasia were based on opinions of 1. euthanasia being morally wrong, 2. fear of possible negative effects on society, 3. euthanasia causing strain on physicians and 4. doubts about the true meaning of requests of euthanasia from patients. Arguments supporting euthanasia were based on 1. patients' autonomy and 2. the relief of suffering, which could be caused by severe illnesses, reduced integrity, hopelessness, social factors and old age. There are several contradictions in the students' arguments and the results indicate a possible need for education focusing on the possibility of symptom control in palliative care and patients' perceived quality of life.

The habenular complex in the epithalamus consists of distinct regions with diverse neuronal populations. Past studies have suggested a role for the habenula in voluntary exercise motivation and reinforcement of intracranial self-stimulation but have not assigned these effects to specific habenula subnuclei. Here, we have developed a genetic model in which neurons of the dorsal medial habenula (dMHb) are developmentally eliminated, via tissue-specific deletion of the transcription factor Pou4f1 (Brn3a). Mice with dMHb lesions perform poorly in motivation-based locomotor behaviors, such as voluntary wheel running and the accelerating rotarod, but show only minor abnormalities in gait and balance and exhibit normal levels of basal locomotion. These mice also show deficits in sucrose preference, but not in the forced swim test, two measures of depression-related phenotypes in rodents. We have also used Cre recombinase-mediated expression of channelrhodopsin-2 and halorhodopsin to activate dMHb neurons or silence their output in freely moving mice, respectively. Optical activation of the dMHb in vivo supports intracranial self-stimulation, showing that dMHb activity is intrinsically reinforcing, whereas optical silencing of dMHb outputs is aversive. Together, our findings demonstrate that the dMHb is involved in exercise motivation and the regulation of hedonic state, and is part of an intrinsic reinforcement circuit.

Active ending of the life of a newborn baby is a crime. Yet its clandestine practise is a reality in several European countries. In this paper, we defend the necessity to institute a proper legal frame for what we define as active neonatal euthanasia. The only legal attempt so far, the Dutch Groningen protocol, is not satisfactory. We critically analyse this protocol, as well as several other clinical practises and philosophical stances. Furthermore, we have tried to integrate our opinions as clinicians into a law project, with the purpose of pinpointing several issues, specific of perinatality that should be addressed by such a law. In conclusion, we argue that the legalisation of neonatal euthanasia under exceptional circumstances is the only way to avoid all the “well-intentioned” malpractices associated with ending life at the very dawn of it.

Both in the general public and in the professional communities, very diverse notions of euthanasia can be found. At the same time determining of the precise semantics of euthanasia is one of the crucial prerequisites for subsequent meaningful ethical discussion of euthanasia. The paper analyzes an empirical study investigating the understanding of euthanasia by medical students. The aim of the conducted research was to identify the semantic definitions of euthanasia used by the first-year medical students.
Using religious orientation paradigm, this twofold study examined the relationship between euthanasia attitude and religiosity, and compared single-item and multi-item scales of euthanasia attitude. Three hundred students were asked whether they view euthanasia as moral. In addition, participants completed the Euthanasia Attitude Scale (EAS) and Religious Orientation Scale-Revised. Results indicated that intrinsic religiosity was the strongest correlate of negative attitudes toward euthanasia. This type of religiosity explained additional variance when added to the two types of extrinsic religiosity (social, personal), but the reverse was not the case. The fairly strong correlation of intrinsic religiosity with the EAS provides evidence of construct validity for the EAS and proved it to be a better measure for assessing euthanasia attitude, rather than the single-item scale.

The exteroceptive suppression of voluntary electromyographic activity of the masseter and temporal muscles was studied in healthy volunteers and patients with paroxysmal neuropathic pain (trigeminal neuralgia). The latent period of the exteroceptive suppression was prolonged and the duration of its late fragment was shortened in the patients in comparison with normal subjects. A short exteroceptive suppression period in patients with trigeminal neuralgia reflected deficient activity of inhibitory interneurons of the reflector loop and excessive activity of the antinociceptive system of the brain stem, while prolongation of the latent period reflected prolongation of inhibitory interneurons activation. A direct correlation between the degree of changes in the exteroceptive suppression parameters and pain intensity, evaluated by the patients by the visual analog scale, was detected.

The recent enactment of a law that allows infant euthanasia in Belgium raises questions with varied answers. To contribute to a better understanding of the topic, euthanasia and legislation concepts are described. After a bioethical analysis, we propose as conclusion that children euthanasia could only be acceptable in very exceptional situations in which palliative measures have failed. The answer should be that it is not acceptable in our setting, not until we have public policies, protocols and palliative care services for terminally ill children.

As euthanasia has become a widely debated issue in many Western countries, hospitals and nursing homes especially are increasingly being confronted with this ethically sensitive societal issue. The focus of this paper is how healthcare institutions can deal with euthanasia requests on an organizational level by means of a written institutional ethics policy. The general aim is to make a critical analysis whether these policies can be considered as organizational-ethical instruments that support healthcare institutions to take their institutional responsibility for dealing with euthanasia requests. By means of an interpretative analysis, we conducted a process of reinterpretation of results of former Belgian empirical studies on written institutional ethics policies on euthanasia in dialogue with the existing international literature. The study findings revealed that legal regulations, ethical and care-oriented aspects strongly affected the development, the content, and the impact of written institutional ethics policies on euthanasia. Hence, these three cornerstones-law, care and ethics-constituted the basis for the empirical-based organizational-ethical framework for written institutional ethics policies on euthanasia that is presented in this paper. However, having a euthanasia policy does not automatically lead to more legal transparency, or to a more professional and ethical care practice. The study findings suggest that the development and implementation of an ethics policy on euthanasia as an organizational-ethical instrument should be considered as a dynamic process. Administrators and ethics committees must take responsibility to actively create an ethical climate supporting care providers who have to deal with ethical dilemmas in their practice.

Children with disabilities were killed during the Nazi era, often by nurses. Some nurses killed children, saying that they were under orders. Propaganda about the need for "racial purity" was all pervasive and influenced much of the population, including nurses. The German people accepted the "mercy" killing of children with disabilities. We describe the children's "euthanasia" program, explore the influence of propaganda, ask why it was acceptable to kill children, and provide historical context demonstrating "slippery slopes" which can lead to abrogation of ethical principles. Discussion of such history is essential as the ethical principles which were breached are still the cornerstone of nursing practice today. Only by openly discussing past wrongs can we attempt to ensure that they do not happen again. Archival documents from Germany and Israel, including trial depositions and transcripts, provided material, supplemented by secondary classic sources.

Decisions about neonatal end-of-life care have been studied intensely over the last 20 years in The Netherlands. Nationwide surveys were done to quantify these decisions, provide details and monitor the effect of guidelines, new regulations and other interventions. One of those interventions was the Groningen Protocol for newborn euthanasia in severely ill newborns, published in 2005. Before publication, an estimated 20 cases of euthanasia per year were performed. After publication, only two cases in five years were reported. Studies suggested that this might be partly caused by the lack of consensus about the dividing line between euthanasia and palliative care. New recommendations about paralytic medication use in dying newborns were issued to increase transparency and to improve reporting of euthanasia. New surveys will be needed to measure the effects of these interventions. This cycle of interventions and measurements seems useful for continuous improvement of end-of-life care in newborns.
In February 2014 the Belgian parliament voted to extend the existing euthanasia law to cover children under the age of 18. The law sanctions euthanasia for children with terminal or incurable conditions who are near death, suffering 'constant and unbearable pain', and whose parents and health professionals agree with the decision. The child also has to be interviewed by a psychologist or psychiatrist to ascertain and certify their 'capacity of discernment'.

In the present study, effects of voluntary exercise in an obese animal model were investigated in relation to the rhythm of daily activity and ghrelin production. Male Sprague-Dawley rats were fed either a high fat diet (HFD) or a chow diet (CD) from four to 16 weeks old. They were further subdivided into either an exercise group (HFD-Ex, CD-Ex) with a running wheel for three days of every other week or sedentary group (HFD-Se, CD-Se). At 16 weeks old, marked increases in body weight and visceral fat were observed in the HFD-Se group, together with disrupted rhythms of feeding and locomotor activity. The induction of voluntary exercise brought about an effective reduction of weight and fat, and ameliorated abnormal rhythms of activity and feeding in the HFD-Ex rats. Wheel counts as voluntary exercise was greater in HFD-Ex rats than those in CD-Ex rats. The HFD-obese had exhibited a deterioration of ghrelin production, which was restored by the induction of voluntary exercise. These findings demonstrated that abnormal rhythms of feeding and locomotor activity in HFD-obese rats were restored by infrequent voluntary exercise with a concomitant amelioration of the ghrelin production and weight reduction. Because ghrelin is related to food anticipatory activity, it is plausible that ghrelin participates in the circadian rhythm of daily activity including eating behavior. A beneficial effect of voluntary exercise has now been confirmed in terms of the amelioration of the daily rhythms in eating behavior and physical activity in an animal model of obesity.
While people might not be familiar with the term "voluntary arts", they are probably either involved with some voluntary arts activity themselves or they know someone who is. They use "voluntary arts" to mean any situation in which someone is voluntarily participating in an art form for pleasure, social reasons, skills…
Given its preoccupation with the doctor's agency in administering euthanasia, the legal discourse on euthanasia in India has neglected the moral relevance of the patient's suffering in determining the legitimate types of euthanasia. In this paper, I begin by explicating the condition for the possibility of euthanasia in terms of the following moral principle: the doctor ought to give priority to the patient's suffering over the patient's life. I argue that the form of passive euthanasia legally permissible in India is inconsistent with this moral principle, owing to the consequences it entails for the patient. Inevitably, it is acts of commission on the part of the doctor that can provide the best possible death, which is the moral objective of euthanasia. To meet this objective, doctors must be seen as agents who possess the moral integrity and technical expertise to judge when and how the patient’s life ought to be terminated, depending on the patient’s medical condition. They are not bound to save lives and provide care unconditionally.

The role of the cerebellum in motivation and addictive behaviors is less understood than that in control and coordination of movements. High running can be a self-rewarding behavior exhibiting addictive properties. Changes in the cerebellum transcriptional networks of mice from a line selectively bred for High voluntary running (H) were profiled relative to an unselected Control (C) line. The environmental modulation of these changes was assessed both in activity environments corresponding to 7 days of Free (F) access to running wheel and to Blocked (B) access on day 7. Overall, 457 genes exhibited a significant (FDR-adjusted P-value < 0.05) genotype-by-environment interaction effect, indicating that activity genotype differences in gene expression depend on environmental access to running. Among these genes, network analysis highlighted 6 genes (Nrgn, Drd2, Rxrg, Gda, Adora2a, and Rab40b) connected by their products that displayed opposite expression patterns in the activity genotype contrast within the B and F environments. The comparison of network expression topologies suggests that selection for high voluntary running is linked to a predominant dysregulation of hub genes in the F environment that enables running whereas a dysregulation of ancillary genes is favored in the B environment that blocks running. Genes associated with locomotor regulation, signaling pathways, reward-processing, goal-focused, and reward-dependent behaviors exhibited significant genotype-by-environment interaction (e.g. Pak6, Adora2a, Drd2, and Arhgap8). Neuropeptide genes including Adcyap1, Cck, Sst, Vgf, Npy, Nts, Penk, and Tac2 and related receptor genes also exhibited significant genotype-by-environment interaction. The majority of the 183 differentially expressed genes between activity genotypes (e.g. Drd1) were under-expressed in C relative to H genotypes and were also under-expressed in B relative to F environments. Our findings indicate that the high voluntary running mouse

We evaluated the effect of voluntary exercise on spontaneous physical activity (SPA) and food consumption in mice from 4 replicate lines bred for 57 generations for high voluntary wheel running (HR) and from 4 non-selected control (C) lines. Beginning at ~24 days of age, mice were housed in standard cages or in cages with attached wheels. Wheel activity and SPA were monitored in 1-min intervals. Data from the 8th week of the experiment were analyzed because mice were sexually mature and had plateaued in body mass, weekly wheel running distance, SPA, and food consumption. Body mass, length, and masses of the retroperitoneal fat pad, liver, and heart were recorded after the 13th week. SPA of both HR and C mice decreased with wheel access, due to reductions in both duration and average intensity of SPA. However, total activity duration (SPA+wheel running; min/day) was ~1/3 greater when mice were housed with wheels, and food consumption was significantly increased. Overall, food consumption in both HR and C mice was more strongly affected by wheel running than by SPA. Duration of wheel running had a stronger effect than average speed, but the opposite was true for SPA. With body mass as a covariate, chronic wheel access significantly reduced fat pad mass and increased heart mass in both HR and C mice. Given that both HR and C mice housed with wheels had increased food consumption, the energetic cost of wheel running was not fully compensated by concomitant reductions in SPA. The experiment demonstrates that both duration and intensity of both wheel running and SPA were significant predictors of food consumption. This sort of detailed analysis of the effects of different aspects of physical activity on food consumption has not previously been reported for a non-human animal, and it sets the stage for longitudinal examination of energy balance and its components in rodent models.
This article deals with the euthanasia debate in light of new life-sustaining technologies such as the left ventricular assist device (LVAD). The question arises: does the switching off of a LVAD by a doctor upon the request of a patient amount to active or passive euthanasia, i.e. to 'killing' or to 'letting die'? The answer hinges on whether the device is to be regarded as a proper part of the patient's body or as something external. We usually regard the switching off of an internal device as killing, whereas the deactivation of an external device is seen as 'letting die'. The case is notoriously difficult to decide for hybrid devices such as LVADs, which are partly inside and partly outside the patient's body. Additionally, on a methodological level, I will argue that the 'ontological' arguments from analogy given for both sides are problematic. Given the impasse facing the ontological arguments, complementary phenomenological arguments deserve closer inspection. In particular, we should consider whether phenomenologically the LVAD is perceived as a body part or as an external device. I will support the thesis that the deactivation of a LVAD is to be regarded as passive euthanasia if the device is not perceived by the patient as a part of the body proper.

Effective pain management for rats and mice is crucial due to the continuing increase in the use of these species in biomedical research. Here we used a recently validated operant orofacial pain assay to determine dose–response curves for buprenorphine and tramadol when mixed in nut paste and administered to male and female rats. Statistically significant analgesic doses of tramadol in nut paste included doses of 20, 30, and 40 mg/kg for female rats but only 40 mg/kg for male rats. For male rats receiving buprenorphine mixed in nut paste, a significant analgesic response was observed at 0.5 and 0.6 mg/kg. None of the doses tested produced a significant analgesic response in female rats. Our results indicate that at the doses tested, tramadol and buprenorphine produced an analgesic response in male rats. In female rats, tramadol shows a higher analgesic effect than buprenorphine. The analgesic effects observed 60 min after administration of the statistically significant oral doses of both drugs were similar to the analgesic effects of 0.03 mg/kg subcutaneous buprenorphine 30 min after administration. The method of voluntary ingestion could be effective, is easy to use, and would minimize stress to the rats during the immediate postoperative period. PMID:26817983

A number of programs have focused on scale-up and implementation research regarding voluntary medical male circumcision; however, there is limited research with regard to factors and strategies related to abstinence compliance and the effects of resuming sex during the wound healing period (42-day post-circumcision). We searched the literature for peer-reviewed articles examining early resumption of sex during this period. This review identifies factors that may predispose a client to engage in sex during the 42-day postoperative period, examines how early resumption of sex can inhibit wound healing and increase seroconversion, and reviews strategies that may increase adherence to abstinence during the wound healing period. We found that the most common factor that may predispose a client to engage in sex before the end of the postoperative period is marriage or cohabitation with a sexual partner. With regard to the effect of sex during the postoperative period on wound healing and seroconversion, we found that adverse events incurred were mild, and there was an increased risk of seroconversion. The only strategy studied to increase compliance to abstinence during the postoperative period utilized text messaging, and the trial results indicate that text messaging did not increase abstinence compliance.

Consortium for Earthquake-Damaged Cultural Heritage (CEDACH) is a voluntary initiative launched just after the Great East Japan Earthquake on 11 March 2011. The consortium is developing a social network between local cultural resource managers restoring disaster-damaged cultural heritage on one side and remote researchers including historians, archaeologists and specialists of cultural information studies on the other side, in order to facilitate collaborative projects. This paper presents three projects in which CEDACH contributed to the development of a digital inventory for disaster-damaged heritage management through web-based collaborations by self-motivated workers. The first project, CEDACH GIS, developed an online archaeological site inventory for the disaster area. Although a number of individuals voluntarily participated in the project at the beginning, it gradually stagnated due to limited need for local rescue archaeology. However, the experience of online-based collaborations worked well for the second project proposed by local specialists, in which CEDACH restored the book catalogue of a tsunami-devastated research library. This experience highlighted the need for online education to improve information and communication technologies (ICT) skills of data builders. Therefore, in the third project called CEDACHeLi, an e-Learning management system was developed to facilitate learning the fundamental knowledge and techniques required for information processing in rescue operations of disaster-damaged cultural heritage. This system will contribute to improved skills and motivation of potential workers for further developments in digital heritage inventory.

Circadian rhythms are highly important not only for the synchronization of animals and humans with their periodic environment but also for their fitness. Accordingly, the disruption of the circadian system may have adverse consequences. A certain number of animals in our breeding stock of Djungarian hamsters are episodically active throughout the day. Also body temperature and melatonin lack 24-h rhythms. Obviously in these animals, the suprachiasmatic nuclei (SCN) as the central pacemaker do not generate a circadian signal. Moreover, these so-called arrhythmic (AR) hamsters have cognitive deficits. Since motor activity is believed to stabilize circadian rhythms, we investigated the effect of voluntary wheel running. Hamsters were bred and kept under standardized housing conditions with food and water ad libitum and a 14 L/10 D lighting regimen. AR animals were selected according to their activity pattern obtained by means of passive infrared motion detectors. In a first step, the daily activity behavior was investigated for 3 weeks each without and with running wheels. To estimate putative photic masking effects, hamsters were exposed to light (LPs) and DPs and also released into constant darkness for a minimum of 3 weeks. A novel object recognition (NOR) test was performed to evaluate cognitive abilities both before and after 3 weeks of wheel availability. The activity patterns of hamsters with low wheel activity were still AR. With more intense running, daily patterns with higher values in the dark time were obtained. Obviously, this was due to masking as LPs did suppress and DPs induced motor activity. When transferred to constant darkness, in some animals the daily rhythm disappeared. In other hamsters, namely those which used the wheels most actively, the rhythm was preserved and free-ran, what can be taken as indication of a reconstitution of circadian rhythmicity. Also, animals showing a 24-h activity pattern after 3 weeks of extensive wheel running were

Buprenorphine HCl (BUP) is a μ-opioid agonist used in laboratory rodents. New formulations of buprenorphine (for example, sustained-released buprenorphine [BUP SR], extended-release buprenorphine [BUP ER]) have been developed to extend the analgesic duration. In a crossover design, 8 adult rats were injected subcutaneously with either BUP, BUP SR, BUP ER, or saline, after which voluntary running-wheel activity, arterial blood gases, and thermal withdrawal latency were assessed. Wheel running was decreased at 24 h compared with baseline in all treatment groups but returned to baseline by 48 h. Arterial pH, HCO3–, and CO2 were not changed between groups or over time. However, arterial oxygen was lower than baseline in the BUP (–8 ± 2 mm Hg), BUP SR (–7 ± 1 mm Hg), and BUP ER (–17 ± 2 mm Hg) groups compared with saline controls (3 ± 2 mm Hg); the BUP ER group showed the greatest decrease when all time points were combined. BUP increased the withdrawal latency at 1 h (15% ± 3%), whereas BUP ER increased latencies at 4, 8, 12, and 48 h (35% ± 11%, 21% ± 7%, 26% ± 7%, and 22% ± 9%, respectively) and BUP SR prolonged latencies at 24, 48, and 72 h (15% ± 6%, 18% ± 5%, and 20% ± 8%, respectively). The duration of thermal analgesia varied between buprenorphine formulations, but all 3 formulations reduced voluntary-running activity at 24 h after injection and might cause hypoxemia in normal adult rats.

Several questions have been raised in recent years about the euthanasia of laboratory rodents. Euthanasia using inhaled agents is considered to be a suitable aesthetic method for use with a large number of animals simultaneously. Nevertheless, its aversive potential has been criticized in terms of animal welfare. The data available regarding the use of carbon dioxide (CO2), inhaled anaesthetics (such as isoflurane, sevoflurane, halothane and enflurane), as well as carbon monoxide and inert gases are discussed throughout this review. Euthanasia of fetuses and neonates is also addressed. A table listing currently available information to ease access to data regarding euthanasia techniques using gaseous agents in laboratory rodents was compiled. Regarding better animal welfare, there is currently insufficient evidence to advocate banning or replacing CO2 in the euthanasia of rodents; however, there are hints that alternative gases are more humane. The exposure to a volatile anaesthetic gas before loss of consciousness has been proposed by some scientific studies to minimize distress; however, the impact of such a measure is not clear. Areas of inconsistency within the euthanasia literature have been highlighted recently and stem from insufficient knowledge, especially regarding the advantages of the administration of isoflurane or sevoflurane over CO2, or other methods, before loss of consciousness. Alternative methods to minimize distress may include the development of techniques aimed at inducing death in the home cage of animals. Scientific outcomes have to be considered before choosing the most suitable euthanasia method to obtain the best results and accomplish the 3Rs (replacement, reduction and refinement).

It is well known that inactivity/activity influences skeletal muscle physiological characteristics. However, the effects of inactivity/activity on muscle weakness and increased susceptibility to muscle contraction-induced injury have not been extensively studied in mdx mice, a murine model of Duchenne muscular dystrophy with dystrophin deficiency. In the present study, we demonstrate that inactivity (ie, leg immobilization) worsened the muscle weakness and the susceptibility to contraction-induced injury in mdx mice. Inactivity also mimicked these two dystrophic features in wild-type mice. In contrast, we demonstrate that these parameters can be improved by activity (ie, voluntary wheel running) in mdx mice. Biochemical analyses indicate that the changes induced by inactivity/activity were not related to fiber-type transition but were associated with altered expression of different genes involved in fiber growth (GDF8), structure (Actg1), and calcium homeostasis (Stim1 and Jph1). However, activity reduced left ventricular function (ie, ejection and shortening fractions) in mdx, but not C57, mice. Altogether, our study suggests that muscle weakness and susceptibility to contraction-induced injury in dystrophic muscle could be attributable, at least in part, to inactivity. It also suggests that activity exerts a beneficial effect on dystrophic skeletal muscle but not on the heart.
Indication of euthanasia is only one of several medical decisions at the end of life. Precise definition of this topic related to the clinical events happening around the sick-bed is not complete in the legal and medical literature. The present review attempts to classify the different end of life events with the aim of clarifying which of these do not belong to the concept of passive euthanasia. Euthanasia is not a legal category. The everyday expressions of active and passive euthanasia are simplifications, which cover actions of different purposes. Use of these in medical and legal literature can be confusing and misleading. We differentiate decisions at the end of life on basis of their purpose. Based on the definition and category of the Hungarian Doctors' Chamber, euthanasia is the act or the lack of action in order to mercifully shorten or end the life of a suffering fellow-man to help him. Concepts of active, passive and forced euthanasia are defined. The terms of indirect and intermediate euthanasia are not used in order to avoid misunderstanding. Help and participation of non-professionals in the implementation cannot be completely excluded from the concept of euthanasia, and we believe euthanasia is not merely related to doctors. We outline those medical decisions at the end of life which do not belong to the category of passive euthanasia, namely: withdrawal of ineffective and life sustaining treatments, letting go of the patient, contra-indication of therapy escalation, use of palliative therapy, pain-relieving treatment, compromise medicine, consideration of reanimation and choosing cost-effective therapy. We touch upon the subject of the living will, why it cannot be applied, and its relation to active and passive euthanasia. With reference to the legal regulation of life saving and life sustaining treatment, we deal with the expected spirit of medical legislation.

Major depression is a complex disorder characterized by genetic and environmental interactions. Selective serotonin reuptake inhibitors (SSRIs) effectively treat depression. Neurogenesis following chronic antidepressant treatment activates brain derived neurotrophic factor (BDNF) signaling. In this study, we analyzed the effects of the SSRI fluvoxamine (Flu) on locomotor activity and forced-swim behavior using chronic dexamethasone (cDEX) infusions in mice, which engenders depression-like behavior. Infusion of cDEX decreased body weight and produced a trend towards lower locomotor activity during darkness. In the forced-swim test, cDEX-mice exhibited increased immobility times compared with mice administered saline. Flu treatment reversed decreased locomotor activity and mitigated forced-swim test immobility. Real-time polymerase chain reactions using brain RNA samples yielded significantly lower BDNF mRNA levels in cDEX-mice compared with the saline group. Endoplasmic reticulum stress-associated X-box binding protein-1 (XBP1) gene expression was lower in cDEX-mice compared with the saline group. However, marked expression of the XBP1 gene was observed in cDEX-mice treated with Flu compared with mice given saline and untreated cDEX-mice. Expression of 5-HT2A and Sigma-1 receptors decreased after cDEX infusion compared with the saline group, and these decreases normalized to control levels upon Flu treatment. Our results indicate that the Flu moderates reductions in voluntary activity following chronic dexamethasone infusions in mice via recovery of BDNF signal cascades.

Background Impaired angiogenesis in cardiac tissue is a major complication of diabetes. Protein kinase B (AKT) and extracellular signal regulated kinase (ERK) signaling pathways play important role during capillary-like network formation in angiogenesis process. Objectives To determine the effects of testosterone and voluntary exercise on levels of vascularity, phosphorylated Akt (P- AKT) and phosphorylated ERK (P-ERK) in heart tissue of diabetic and castrated diabetic rats. Methods Type I diabetes was induced by i.p injection of 50 mg/kg of streptozotocin in animals. After 42 days of treatment with testosterone (2mg/kg/day) or voluntary exercise alone or in combination, heart tissue samples were collected and used for histological evaluation and determination of P-AKT and P-ERK levels by ELISA method. Results Our results showed that either testosterone or exercise increased capillarity, P-AKT, and P-ERK levels in the heart of diabetic rats. Treatment of diabetic rats with testosterone and exercise had a synergistic effect on capillarity, P-AKT, and P-ERK levels in heart. Furthermore, in the castrated diabetes group, capillarity, P-AKT, and P-ERK levels significantly decreased in the heart, whereas either testosterone treatment or exercise training reversed these effects. Also, simultaneous treatment of castrated diabetic rats with testosterone and exercise had an additive effect on P-AKT and P-ERK levels. Conclusion Our findings suggest that testosterone and exercise alone or together can increase angiogenesis in the heart of diabetic and castrated diabetic rats. The proangiogenesis effects of testosterone and exercise are associated with the enhanced activation of AKT and ERK1/2 in heart tissue.

Abstract Background Euthanasia is one of the most intriguing ethical, medical and law issues that marked whole XX century and beginning of the XXI century, sharply dividing scientific and unscientific public to its supporters and opponents. It also appears as one of the points where all three major religions (Catholic, Orthodox, and Islamic) have the same view. They are strongly against legalizing mercy killing, emphasizing the holiness of life as a primary criterion by which the countries should start in their considerations. Studying criminal justice systems in the world, the authors concluded that the issue of deprivation of life from compassion is solved on three ways. On the first place, we have countries where euthanasia is murder like any other murder from the criminal codes. Second, the most numerous are states where euthanasia is murder committed under privilege circumstances. On the third place, in the Western Europe we have countries where euthanasia is a legal medical procedure, under requirements prescribed by the law. In this paper, authors have made a brief comparison of the solutions that exist in some Islamic countries, where euthanasia is a murder, with Western countries, where it represents completely decriminalized medical procedure.

Obesity is associated with increased colonic inflammation, which elevates the risk of colon cancer. Although exercise exerts anti-inflammatory actions in multiple chronic diseases associated with inflammation, it is unknown whether this strategy prevents colonic inflammation in obesity. We hypothesized that voluntary exercise would suppress colonic inflammation in high-fat diet (HFD)-induced obesity by modulation of peroxisome proliferator-activated receptor (PPAR)-γ. Male C57Bl/6J mice fed either a control diet (6.5% fat, CON) or a high-fat diet (24% fat, HFD) were divided into sedentary, voluntary exercise or voluntary exercise with PPAR-γ antagonist GW9662 (10 mg/kg/day). All interventions took place for 12 weeks. Compared with CON-sedentary group, HFD-sedentary mice gained significantly more body weight and exhibited metabolic disorders. Molecular studies revealed that HFD-sedentary mice had increased expression of inflammatory mediators and activation of nuclear factor (NF)-κB in the colons, which were associated with decreased expression and activity of PPAR-γ. Voluntary exercise markedly attenuated body weight gain, improved metabolic disorders, and normalized the expression of inflammatory mediators and activation of NF-κB in the colons in HFD-mice while having no effects in CON-animals. Moreover, voluntary exercise significantly increased expression and activity of PPAR-γ in the colons in both HFD- and CON-animals. However, all of these beneficial effects induced by voluntary exercise were abolished by GW9662, which inhibited expression and activity of PPAR-γ. The results suggest that decreased PPAR-γ activity in the colon of HFD-induced obesity may facilitate the inflammatory response and colon carcinogenesis. Voluntary exercise prevents colonic inflammation in HFD-induced obesity by up-regulating PPAR-γ activity. - Highlights: • Obesity down-regulates PPAR-γ in the colon. • Down-regulated colonic PPAR-γ may facilitate inflammatory

Attitudes towards assisted death activities among medical students, the future health gatekeepers, are scarce and controversial. The aims of this study were to explore attitudes on euthanasia and physician-assisted suicide among final year medical students in Athens, to investigate potential differences in attitudes between male and female medical students and to review worldwide attitudes of medical students regarding assisted death activities. A 20- item questionnaire was used. The total number of participants was 251 (mean age 24.7±1.8 years). 52.0% and 69.7% of the respondents were for the acceptance of euthanasia and physician-assisted suicide, respectively. Women's attitudes were more often influenced by religious convictions as well as by the fact that there is a risk that physician-assisted suicide might be misused with certain disadvantaged groups. On the other hand, men more often believed that a request for physician-assisted suicide from a terminally ill patient is prima-facie evidence of a mental disorder, usually depression. Concerning attitudes towards euthanasia among medical students in various countries there are contradictory results. In USA, the Netherlands, Hungary and Switzerland most of the students supported euthanasia and physician-assisted suicide. However, in many other countries such as Norway, Sweden, Yugoslavia, Italy, Germany, Sudan, Malaysia and Puerto Rico most students expressed negative positions regarding euthanasia and physician assisted suicide.

If physician-assisted suicide/euthanasia is legalised in the UK, this may be the work of GPs. In the absence of recent or comprehensive evidence about GPs' views on either legalisation or willingness to take part, a questionnaire survey of all Welsh GPs was conducted of whom 1202 (65%) responded. Seven hundred and fifty (62.4% of responders) and 671 (55.8% of responders) said that they did not favour a change in the law to allow physician-assisted suicide/voluntary euthanasia respectively. These data provide a rational basis for determining the position of primary care on this contentious issue. PMID:16762127

Information on euthanasia attitudes was obtained from fixed-schedule interviews gathered from 331 respondents. It was found that a favorable attitude toward euthanasia coincided with (1) belief in an afterlife; (2) a less favorable attitude toward euthanasia if relatives make the decision; and (3) younger respondents.

Over many decades Walter Creutz, medical officer in the provincial administration of Rhine Province from 1935 to 1945, was held to be one of the few psychiatrists who had actively opposed the Nazi "Euthanasia" program. In the famous "Euthanasia trial" in Düsseldorf from 1948 to 1950, Creutz was acquitted of complicity in murder; the court attested that he had done his best to sabotage the "Euthanasia" program and in so doing had saved up to 3,000 patients in the Rhineland. This rendering was circulated further in the history of science literature, so that the Rhine Province was considered to be a center of resistance to the "Euthanasia" program. Doubts about this portrayal have arisen since the 1980s. Various authors attempted to prove that Walter Creutz collaborated with the "Euthanasia" apparatus claiming there was no evidence of opposition or resistance or only to a very limited degree. However, this new perspective is based on an equally one-sided, at times grossly distorted analysis of the sources. The article provides building blocks for a more differentiated interpretation.

Damien and John Keown claim that there is important common ground between Buddhism and Christianity on the issue of euthanasia and that both traditions oppose it for similar reasons in order to espouse a "sanctity of life" position. I argue that the appearance of consensus is partly created by their failure to specify clearly enough certain key notions in the argument: particularly Buddhism, euthanasia and the sanctity of life. Once this is done, the Keowns' central claims can be seen to be either false or only restrictedly true.

In Belgium, the GP can perform euthanasia or be called as a consultant. He must know the laws concerning the end of life and be able to explain his rights to his patients. He will know the best practices and techniques for euthanasia. If necessary, he will call help or refer to a more competent colleague. He negotiates with the patient an advanced care planning following the evolution of its pathologies and will witness its wishes regarding end of life against other institutions and doctors.

Issues pertaining to euthanasia, assisted suicide, and cessation of life support continue to be a subject of worldwide interest. Euthanasia- particularly "active" euthanasia- is not considered legally or socially acceptable in most countries. In Japan, the first judgment of a case involving euthanasia took place in 1949. Since then there have been another five cases that reached the point of sentencing in 1990. All six cases were examples of so called "active euthanasia", in which the termination of life was performed by family members. However, the focus of discussion has been changed dramatically in recent years, owing to two prominent cases of mercy killing in 1995 (Yokohama) and 1996 (Kyoto), respectively. Medical doctors were involved in both of these cases, and euthanasia moved from being a theoretical problem to a practical dilemma. These cases also drew attention to the fact that assisted suicide could be distinguished from euthanasia. The first part of this paper will summarize the current status of euthanasia and the cessation of life support in Japan, focusing on its historical background and policy. The second part will briefly sketch the characteristics of Japanese law and then will examine the two recent cases of mercy killing mentioned above to try and determine the roles of whistle blowing in the medical practice arena, with particular reference to Japanese culture. This analysis is a challenge to elucidate how ethics and the law interact, and influence medical practice in a specific cultural context.

Neurofeedback (NF) based on real-time functional magnetic resonance imaging (rt-fMRI) allows voluntary regulation of the activity in a selected brain region. For the training of this regulation, a well-designed feedback system is required. Social reward may serve as an effective incentive in NF paradigms, but its efficiency has not yet been tested. Therefore, we developed a social reward NF paradigm and assessed it in comparison with a typical visual NF paradigm (moving bar). We trained twenty-four healthy participants, on three consecutive days, to control activation in dorsal anterior cingulate cortex (ACC) with fMRI-based NF. In the social feedback group, an avatar gradually smiled when ACC activity increased, whereas in the standard feedback group, a moving bar indicated the activation level. In order to assess a transfer of the NF training both groups were asked to up-regulate their brain activity without receiving feedback immediately before and after the NF training (pre- and post-test). Finally, the effect of the acquired NF training on ACC function was evaluated in a cognitive interference task (Simon task) during the pre- and post-test. Social reward led to stronger activity in the ACC and reward-related areas during the NF training when compared to standard feedback. After the training, both groups were able to regulate ACC without receiving feedback, with a trend for stronger responses in the social feedback group. Moreover, despite a lack of behavioral differences, significant higher ACC activations emerged in the cognitive interference task, reflecting a stronger generalization of the NF training on cognitive interference processing after social feedback. Social reward can increase self-regulation in fMRI-based NF and strengthen its effects on neural processing in related tasks, such as cognitive interference. A particular advantage of social feedback is that a direct external reward is provided as in natural social interactions, opening perspectives

This study of chronic incomplete spinal cord injury (SCI) subjects investigated patterns of central motor drive (i.e., central activation) of the plantar flexors using interpolated twitches, and modulation of soleus H-reflexes during lengthening, isometric, and shortening muscle actions. In a recent study of the knee extensors, SCI subjects demonstrated greater central activation ratio (CAR) values during lengthening (i.e., eccentric) maximal voluntary contractions (MVCs), compared with during isometric or shortening (i.e., concentric) MVCs. In contrast, healthy controls demonstrated lower lengthening CAR values compared with their isometric and shortening CARs. For the present investigation, we hypothesized SCI subjects would again produce their highest CAR values during lengthening MVCs, and that these increases in central activation were partially attributable to greater efficacy of Ia-α motoneuron transmission during muscle lengthening following SCI. Results show SCI subjects produced higher CAR values during lengthening vs. isometric or shortening MVCs (all P < 0.001). H-reflex testing revealed normalized H-reflexes (maximal SOL H-reflex-to-maximal M-wave ratios) were greater for SCI than controls during passive (P = 0.023) and active (i.e., 75% MVC; P = 0.017) lengthening, suggesting facilitation of Ia transmission post-SCI. Additionally, measures of spinal reflex excitability (passive lengthening maximal SOL H-reflex-to-maximal M-wave ratio) in SCI were positively correlated with soleus electromyographic activity and CAR values during lengthening MVCs (both P < 0.05). The present study presents evidence that patterns of dynamic muscle activation are altered following SCI, and that greater central activation during lengthening contractions is partly due to enhanced efficacy of Ia-α motoneuron transmission.

Motor surround inhibition is the neural mechanism that selectively favors the contraction of target muscles and inhibits nearby muscles to prevent unwanted movements. This inhibition was previously reported at the onset of a movement, but not during a tonic contraction. Cerebellar brain inhibition (CBI) is reduced in active muscles during tonic activation; however, it has not been studied in the surround muscles. CBI was evaluated in the first dorsal interosseus (FDI) as the target muscle, and the abductor digiti minimi (ADM), flexor carpi radialis (FCR), and extensor carpi radialis (ECR) as surround muscles during rest and tonic activation of FDI in fourteen subjects. Cerebellar stimulation was performed under MRI-guided neuronavigation targeting lobule VIII of the cerebellar hemisphere. Stimulus intensities for cerebellar stimulation were based on the resting motor cortex threshold (RMT) and adjusted for the depth difference between the cerebellar and motor cortices. We used 90% to 120% of adjusted RMT as the conditioning stimulus intensity during rest. The intensity that generated the best CBI at rest in the FDI was selected for use during tonic activation. During selective tonic activation of FDI, CBI was significantly reduced only for FDI but not for the surround muscles. Unconditioned MEP sizes were increased in all muscles during FDI tonic activation compared to rest, despite background EMG activity increasing only for the FDI. Our study suggests that the cerebellum may play an important role in selective tonic finger movement by reducing its inhibition in the motor cortex only for the relevant agonist muscle. PMID:26900871

The debate over the legalisation of voluntary euthanasia is most often seen to be the result of three changes in society: individualisation, diminished taboos concerning death and changes in the balance of power in medicine. The fact that these changes occurred in many western countries but led to legalisation in only a few makes this claim problematic. I examine whether socio-legal propositions, with respect to the emergence of laws which focus on social control, offer a better approach to understanding the development of rules allowing and governing euthanasia. After a short sketch of the history of the Dutch law regulating euthanasia, I discuss these three societal changes in the light of shifts in the social control of medical behaviour that shortens life. I show that the Dutch relaxation of the prohibition of euthanasia goes together with new forms of social control: doctors' self control is complemented with second-party control (by patients), professional third-party control and governmental control. My work calls attention to the fact that bioethics is part of larger systems of social control.

Medical students and physicians should possess basic knowledge concerning medical ethics and palliative care. The aim of the study was to explore the knowledge on the end-of-life ethics and palliative care in third-year medical students and physicians during internal medicine specialty training and their attitude towards breaking bad news and euthanasia. A voluntary and anonymous questionnaire survey with the participation of 401 students and 217 physicians filled after lectures concerning ethics for medical students and after palliative medicine course for physicians during internal medicine specialty training. A total of 28 % students and 24 % physicians (p = 0.282) were ready to reveal full information to advanced cancer patients. A total of 82 % of students and 90 % of physicians (p = 0.008) would not practice euthanasia; 67 % of students and 75 % of physicians (p = 0.039) were opponents of euthanasia legalisation. A total of 70 % doctors and 23 % students indicated oral as the most preferable route of morphine administration. A total of 74 % physicians and 43 % students stated that there is no maximal dose of morphine; 64 % of doctors and 6 % of students indicated constipation as a constant adverse effect of morphine. Breaking bad news is a significant difficulty for both students and physicians. There is a small percentage of those tending to practice euthanasia and bigger accepting its legalisation with fewer physicians than students. In contrast to medical students, the majority of physicians have knowledge concerning chronic morphine use in the treatment of cancer patients.

In Australia and Oregon, USA, legislation to permit statutory sanctioned physician-assisted dying was enacted. However, opponents, many of whom held strong religious views, were successful with repeal in Australia. Similar opposition in Oregon was formidable, but ultimately lost in a 60-40% vote reaffirming physician-assisted dying. This paper examines the human dilemma which arises when technological advances in end-of-life medicine conflict with traditional and religious sanctity-of-life values. Society places high value on personal autonomy, particularly in the United States. We compare the potential for inherent contradictions and arbitrary decisions where patient autonomy is either permitted or forbidden. The broader implications for human experience resulting from new legislation in both Australia and Oregon are discussed. We conclude that allowing autonomy for the terminally ill, within circumscribed options, results in fewer ethical contradictions and greater preservation of dignity. Key Words: Physician-assisted suicide • voluntary euthanasia • patient autonomy • religious belief PMID:10786323

Concentric and eccentric muscle contractions have distinct differences in their neuromuscular and neurophysiologic characteristics. However, although many evidences regarding the features of these types of muscle contraction have emerged, there have been few neuroimaging studies to compare the two types of contractions. Therefore, we investigated whether cortical activity associated with eccentric contraction of the wrist extensors differed from that of concentric contraction, using functional MRI (fMRI). Fifteen right-handed healthy subjects were enrolled in this study. During 4 repeating blocks of eccentric and concentric muscle contraction paradigms, the brain was scanned with fMRI. The differences in the BOLD signal intensities during the performance of eccentric and concentric exercise were compared in the predetermined regions of interest. Our findings revealed that many cortical areas associated with motor performance were activated, including the primary motor area, the inferior parietal lobe, the pre-supplementary area (pre-SMA), the anterior cingulate cortex, the prefrontal area, and the cerebellum. In addition, lower signal intensities were seen in the right primary motor cortex and right cerebellum during eccentric contractions compared with concentric contractions, whereas higher signal intensities were detected in other cortical areas during eccentric contractions. In the study, we demonstrated that eccentric and concentric muscle contractions induced quite different patterns of cortical activity respectively. These findings might be attributed to different strategy of neuro-motor processing and a higher level of cognitive demand for the performance of motor task with a higher degree of difficulty such as that required during eccentric contractions in comparison of concentric contractions.

Data are equivocal on whether voluntary activation is preserved or decreased in old compared to young adults. Further, data are scant on the effect of age on the rate of muscle relaxation when the muscle is contracting voluntarily. Assessment of both measures with transcranial magnetic stimulation (TMS) yields information which cannot be obtained with traditional peripheral nerve stimulation. Hence, voluntary activation and peak relaxation rate of the elbow flexors were assessed with TMS during repeated maximal efforts in 30 men and 28 women between the ages of 22-84 years. Voluntary activation was similar for the two sexes (P = 0.154) and was not affected by age in men (96.2 ± 2.7 %; P = 0.887) or women (95.1 ± 3.0 %; P = 0.546). Men had a significantly faster peak rate of relaxation than women in absolute units (-880.0 ± 223.2 vs. -360.2 ± 78.5 Nm/ s, respectively; P < 0.001) and when normalized to subject strength (-12.5 ± 2.1 vs. -8.7 ± 1.0 s(-1), respectively; P < 0.001). Absolute and normalized relaxation rates slowed with age in men (P = 0.002 and P = 0.006, respectively), but not women (P = 0.142 and P = 0.950, respectively). Across the age range studied, all subjects, regardless of age or sex, were able to achieve high voluntary activation scores for the elbow flexors (~95 %). In contrast, peak relaxation rate was markedly faster in men than women and slowed with age in men but not women. Normalization of relaxation rates to strength did not affect the influence of age or sex.

1. A quantitative study has been made of the reflex effects of sudden changes in mechanical load on contracting human intercostal muscles during willed breathing movements involving the chest wall. Averaging techniques were applied to recordings of electromyogram (EMG) and lung volume, and to other parameters of breathing. 2. Load changes were effected for brief periods (10-150 msec) at any predetermined lung volume by sudden connexion of the airway to a pressure source variable between ± 80 cm H2O so that respiratory movement could be either assisted or opposed. In some experiments airway resistance was suddenly reduced by porting from a high to a low resistance external airway. 3. Contracting inspiratory and expiratory intercostal muscles showed a `silent period' with unloading which is attributed to the sudden withdrawal from intercostal motoneurones of monosynaptic excitation of muscle spindle origin. 4. For both inspiratory and expiratory intercostal muscles the typical immediate effect of an increase in load was an inhibitory response (IR) with a latency of about 22 msec followed by an excitatory response (ER) with a latency of 50-60 msec. 5. It was established using brief duration stimuli (< 40 msec) that the IR depended on mechanical events associated with the onset of stimulation, whereas stimuli greater than 40 msec in duration were required to evoke the ER. 6. For constant expiratory flow rate and a constant load, the ER of expiratory intercostal muscles increased as lung volume decreased within the limits set by maximal activation of the motoneurone pool as residual volume was approached. 7. The ER to a constant load increased directly with the expiratory flow rate at which the load applied, also within limits set by maximal activation of the motoneurone pool. 8. For a given load, the ER during phonation was greater than that occurring at a similar expiratory flow rate without phonation when the resistance of the phonating larynx was mimicked by an

Voluntary wheel running in the mouse is used to assess physical performance and endurance and to model exercise training as a way to enhance health. Wheel running is a voluntary activity in contrast to other experimental exercise models in mice, which rely on aversive stimuli to force active movement. The basic protocol consists of allowing mice to run freely on the open surface of a slanted plastic saucer-shaped wheel placed inside a standard mouse cage. Rotations are electronically transmitted to a USB hub so that frequency and rate of running can be captured to a software program for data storage and analysis for variable time periods. Mice are individually housed so that accurate recordings can be made for each animal. Factors such as mouse strain, gender, age, and individual motivation, which affect running activity, must be considered in the design of experiments using voluntary wheel running. PMID:26629772

This study was designed to evaluate hemodynamic and electrophysiological motor cortex responses to voluntary finger pinching in humans, with simultaneous recording of near-infrared spectroscopy (NIRS) signals and movement-related cortical potentials (MRCP). Six healthy, right-handed subjects performed 100 trials of voluntary right-thumb index-finger pinching with about a 10-second interval at their own pace. Throughout the session, 48 regions over the bilateral motor cortex were assessed by NIRS, while MRCP and electromyogram (EMG) were simultaneously monitored. MRCP started 1536+/-58 ms before EMG onset and peaked 127+/-24 ms after EMG onset. NIRS data showed bilateral prefrontal cortex at 0.5+/-0.1 s before EMG onset and bilateral dorsal premotor cortex activations at 0.6+/-0.1 s before EMG onset. The hand area of the sensorimotor cortex was activated left-dominantly, seen obviously peaked at 3.7+/-0.2 s after EMG onset. The comparison between MRCP and NIRS results raised the possibility that the vascular response to neural activity occurs within 4 s with a voluntary pinch task. These results indicate that our technique allows detailed study of the motor control. Our method is a promising strategy for event-related motor control and neurovascular coupling studies.

A unique polygenic model of rat physical activity has been recently developed where rats were selected for the trait of low voluntary wheel running. We utilized this model to identify differences in soleus and plantaris muscles of sedentary low voluntary wheel running rats and physically active low voluntary wheel running rats exposed to moderate amounts of treadmill training. Three groups of 28-day-old male Wistar rats were used: (1) rats without a running wheel (SEDENTARY, n = 7), (2) rats housed with a running wheel (WHEEL, n = 7), and (3) rats housed with a running wheel and exercised on the treadmill (5 days/week for 20 min/day at 15.0 m/min) (WHEEL + TREADMILL, n = 7). Animals were euthanized 5 weeks after the start of the experiment and the soleus and plantaris muscles were excised and used for analyses. Increases in skeletal muscle gene expression of peroxisome proliferator-activated receptor gamma coactivator 1 alpha and fibronectin type III domain-containing protein 5 in WHEEL + TREADMILL group were observed. Also, WHEEL + TREADMILL had higher protein levels of superoxide dismutase 2 and decreased levels of oxidative damage. Our data demonstrate that the addition of treadmill training induces beneficial muscular adaptations compared to animals with wheel access alone. Furthermore, our data expand our understanding of differential muscular adaptations in response to exercise in mitochondrial, antioxidant, and metabolic markers. PMID:26603455

The generic term "passive euthanasia" includes different issues dealing with the omission, discontinuation or termination of life-sustaining or life-prolonging medical treatments. The debate around passive euthanasia focuses on the constitutional right of self-determination of every human being on the one hand and the constitutional mandate of the State to protect human life on the other. Issues of passive euthanasia always require a differentiated approach. Essentially, it comes down to the following: In Germany, the human right of self-determination includes the right to prohibit the performance of life-sustaining treatments, even if this leads to the death of the patient. A physician who does not take life-sustaining treatment measures because this is the free will expressed by the patient is not subject to prosecution. On the other hand, if the physician treats the patient against his will, this can be deemed a punishable act of bodily injury. The patient's will is decisive even if his concrete state of health does no longer allow him to freely express his will. In the Patient's Living Will Act of 2009, the German legislator clarified the juridical assessment of such constellations being of particular relevance in practice. A written living will of a person in which he requests to take or not to take certain medical treatment measures in case that he is no longer able to make the decision himself shall be binding for the people involved in the process of medical treatment. If there is no living will, the supposed will of the patient shall be relevant. In its judgment in the "Putz case", the German Federal Court of Justice ruled in 2010 that actions terminating a life-sustaining treatment that does not correspond to the patient's will must be limited to letting an already ongoing disease process run its course. In this context it is not important, however, whether treatment is discontinued by an active act or by omission. Under certain circumstances, the

Introduction The aim of this study was to re-evaluate jitter values of healthy subjects in whom pairs of single-fiber-like potentials were recorded from voluntary activated periocular muscles using a disposable 37-mm concentric needle electrode (CNE) with 2-kHz low-cut filtering. Methods We reviewed the recordings of 129 subjects (85 women; 44 men; mean age, 43.8±15.3 years). The m. frontalis group included 116 subjects, and the m. orbicularis oculi group included 18 subjects. Jitter values were expressed as the mean consecutive difference (MCD) of 20 different pairs. Results The mean MCD (n=2680) was 22.5±9.7 μs (range, 5–121 μs), and the upper 95% confidence limit (CL) was 39 μs. The mean of 134 MCD values for each subject was 22.5±3.7 μs (range, 15–33 μs), and the upper 95% CL was 30 μs. The outer limit of the 18th highest MCD values out of 20 recordings for each subject was 31.3±6.5 μs (range, 18–53 μs), with an upper 95% CL of 43.3 μs. Conclusion Using a conventional 37-mm CNE with 2-kHz low-cut filtering may be a cost effective alternative to a single-fiber electrode in periocular muscles if strict criteria are used for acceptable signals. Jitter values of >44 μs that were calculated from single-fiber-like action potential pairs should alert the physician regarding the possibility of neuromuscular junction disorders and constitute an indication for a further diagnostic investigation.

CO₂ is one of the most commonly used euthanasia agents for laboratory animals. Considerable research has gone into the effect of the agent on animals, but little has been done to examine potential human exposure during these procedures. In this study, we examine the CO₂ concentrations to which personnel are exposed while euthanizing rodents with CO₂. To examine the environmental levels of CO₂ generated during euthanasia, we examined several variables including flow rate, inclusion of a cage in the euthanasia chamber, inversion of the euthanasia chamber, chamber size, distance from the euthanasia chamber, and room size. Under all conditions, CO₂ concentrations in the room temporarily increased significantly to 600 to 4000 ppm. The results of this study show that, under several testing scenarios, occupational levels of CO₂ did not exceed governmentally mandated allowable exposure limits during routine rodent euthanasia procedures.

Invertebrate animals have long played an important role in biomedical research in such fields as genetics, physiology, and development. However, with few exceptions, scientists, veterinarians, and technicians have paid little attention to the anesthesia, analgesia, and euthanasia of these diverse creatures. Indeed, some standard research procedures are routinely performed without anesthesia. Yet various chemical agents are available for the immobilization or anesthesia of invertebrates, ranging from gases or volatile liquids that can be pumped into either an anesthetic chamber (for terrestrial species) or a container of water (aquatic species), to benzocaine and other substances for fish. Many invertebrates are not difficult to immobilize or anesthetize and the procedures recommended in this article appear to be safe; however, none should be considered totally risk-free. Analgesia of invertebrates is as yet a largely unexplored field; until scientific data are available, other measures can promote the well-being of these animals in the laboratory. For euthanasia, various methods (physical or chemical or a combination of both) have been recommended for different taxa of invertebrates, but most have not been properly studied under laboratory conditions and some can be problematic in the context of research procedures and tissue harvesting. Furthermore, relevant data are scattered, sometimes available only in languages other than English, and there is no international approach for seeking and collating such information. In this article I review various methods of anesthesia, analgesia, and euthanasia for terrestrial and aquatic invertebrates, as well as areas requiring further research.

Mammals expend energy in many ways, including basic cellular maintenance and repair, digestion, thermoregulation, locomotion, growth and reproduction. These processes can vary tremendously among species and individuals, potentially leading to large variation in daily energy expenditure (DEE). Locomotor energy costs can be substantial for large-bodied species and those with high-activity lifestyles. For humans in industrialized societies, locomotion necessary for daily activities is often relatively low, so it has been presumed that activity energy expenditure and DEE are lower than in our ancestors. Whether this is true and has contributed to a rise in obesity is controversial. In humans, much attention has centered on spontaneous physical activity (SPA) or non-exercise activity thermogenesis (NEAT), the latter sometimes defined so broadly as to include all energy expended due to activity, exclusive of volitional exercise. Given that most people in Western societies engage in little voluntary exercise, increasing NEAT may be an effective way to maintain DEE and combat overweight and obesity. One way to promote NEAT is to decrease the amount of time spent on sedentary behaviours (e.g. watching television). The effects of voluntary exercise on other components of physical activity are highly variable in humans, partly as a function of age, and have rarely been studied in rodents. However, most rodent studies indicate that food consumption increases in the presence of wheels; therefore, other aspects of physical activity are not reduced enough to compensate for the energetic cost of wheel running. Most rodent studies also show negative effects of wheel access on body fat, especially in males. Sedentary behaviours per se have not been studied in rodents in relation to obesity. Several lines of evidence demonstrate the important role of dopamine, in addition to other neural signaling networks (e.g. the endocannabinoid system), in the control of voluntary exercise. A

The impact of euthanasia methods on endocrine and metabolic parameters in rodent tissues and biological fluids is highly relevant for the accuracy and reliability of the data collected. However, few studies concerning this issue are found in the literature. We compared the effects of three euthanasia methods currently used in animal experimentation (i.e. decapitation, CO2 inhalation, and pentobarbital injection) on the serum levels of corticosterone, insulin, glucose, triglycerides, cholesterol and a range of free fatty acids in rats. The corticosterone and insulin levels were not significantly affected by the euthanasia protocol used. However, euthanasia by an overdose of pentobarbital (120 mg/kg intraperitoneal injection) increased the serum levels of glucose, and decreased cholesterol, stearic and arachidonic acids levels compared with euthanasia by CO2 inhalation and decapitation. CO2 inhalation appears to increase the serum levels of triglycerides, while euthanasia by decapitation induced no individual discrepant biomarker level. We conclude that choice of the euthanasia methods are critical for the reliability of serum biomarkers and indicate the importance of selecting adequate euthanasia methods for metabolic analysis in rodents. Decapitation without anaesthesia may be the most adequate method of euthanasia when taking both animal welfare and data quality in consideration. This article is protected by copyright.

Determining ethical standards for laboratory animal euthanasia requires an assessment of the relative amounts of pain and distress caused by different methods. Animal behaviour data are an important indicator of pain and distress, but their interpretation can be controversial; moreover, behaviour is more easily assessed with some euthanasia methods than with others. While every euthanasia method requires careful study, CO2 inhalation has come under close scrutiny both because it is so widely used for rodent euthanasia, and because it has, until recently, long been considered relatively non-aversive.

Euthanasia is an issue that generates an extensive social debate. Euthanasia is generally classified as either active or passive. The former is usually defined as taking specific steps to cause the patient's death, while the latter is described as withdrawal of medical treatment with the deliberate intention of bringing the patient's life to an end. The dispute on euthanasia involves a multitude of aspects including religious, legal, cultural, ethical, medical, and spiritual issues. The purpose of the present study was to examine the views of medical professionals toward the highly controversial issue of euthanasia. Accordingly, the research has been conducted among a group of Polish nurses and physicians working in Intensive Care and Oncology Units. Their views have been compared to those of the control group, which included the members of the general public, who do not work in medical profession. It was expected that the education and training and the day-to-day exposure to vegetative patients might influence the views of medical personnel concerning euthanasia. The research demonstrated that the members of all groups supported liberal views. Conservative views were not popular among the respondents. The physicians turned out to be the least conservative group. The survey has also demonstrated that there is a broad consensus that informational and psychological support should be provided to terminally ill patients and their relatives. The attitude toward the passive form of euthanasia seems to have broad support. In particular doctors tend to approve this form of bringing a terminally ill patient's life to an end. The active euthanasia is regarded with much less favor and physicians, in particular, appear to disapprove of it.

In response to the general prohibition of euthanasia and assisted suicide, some right-to-die activists have developed non-medical methods to covertly hasten death. One such method is a "debreather," a closed system breathing device that laypersons can use to induce hypoxia for persons seeking euthanasia or assisted suicide. This article presents data from nine cases where the debreather was used on humans, resulting in eight deaths. The covert properties of the debreather make it almost impossible for medical examiners and law enforcers to detect its use. Clandestine behavior circumvents legal forms of social control and challenges models for regulated, medicalized euthanasia and assisted suicide. The debreather compromises the ability of forensic investigators to assign an accurate cause and manner of death, and this raises implications for law enforcement, vital statistics, and research into the causes of death. The involvement of lay organizations in euthanasia and assisted suicide means that effective social policy on right-to-die issues must take into account their activities as well as those of other health professionals.

Based on a comprehensive computerized literature search supplemented by a specific manual search of the literature, the present review article focuses on concrete aspects of the application of surface electromyography (EMG) for evaluation of the masticatory muscles in general and of the masseter and anterior temporal muscles in particular, and presents the current base of knowledge on the clinical relevance of surface EMG in dental applications. In the first stage of the review, publications from the year 2000 or later reporting the results of controlled clinical trials (randomized as far as available) of patients with craniomandibular or temporomandibular disorders (TMD) were analyzed. Data from the selected publications were systematically compiled and divided into subject areas as follows: Resting activity, maximal and sub-maximal voluntary contraction, symmetry of EMG activity, and fatigue effects; EMG activity during mastication, factors (including pain) that affect EMG activity, and the impact of adjusting static and dynamic occlusal relationships; Effects of occlusal splints and other occlusal treatments. Surface electromyography is in principle a suitable tool for neuromuscular function analysis in the field of dentistry. If used according to the specific recommendations and in conjunction with a thorough and conscientious clinical history and physical examination, surface EMG measurements can provide objective, documentable, valid, and reproducible data on the functional condition of the masticatory muscles of an individual patient.

Analyzed attitudes of 614 Protestant and Catholic Cleveland clergy toward terminal illness and euthanasia. Clergy responses revealed that, although eager to prolong life, terminally ill patients feared prolonged illness more than death. The controversial nature of euthanasia became more apparent with clergy who had more training in death…

The aim of this article was to review the ethical debate concerning palliative sedation. Although recent guidelines articulate the differences between palliative sedation and euthanasia, the ethical controversies remain. The dominant view is that euthanasia and palliative sedation are morally distinct practices. However, ambiguous moral experiences and considerable practice variation call this view into question. When heterogeneous sedative practices are all labeled as palliative sedation, there is the risk that palliative sedation is expanded to include practices that are actually intended to bring about the patients' death. This troublesome expansion is fostered by an expansive use of the concept of intention such that this decisive ethical concept is no longer restricted to signify the aim in guiding the action. In this article, it is argued that intention should be used in a restricted way. The significance of intention is related to other ethical parameters to demarcate the practice of palliative sedation: terminality, refractory symptoms, proportionality, and separation from other end-of-life decisions. These additional parameters, although not without ethical and practical problems, together formulate a framework to ethically distinguish a more narrowly defined practice of palliative sedation from practices that are tantamount to euthanasia. Finally, the article raises the question as to what impact palliative sedation might have on the practice of palliative care itself. The increasing interest in palliative sedation may reemphasize characteristics of health care that initially encouraged the emergence of palliative care in the first place: the focus on therapy rather than care, the physical dimension rather than the whole person, the individual rather than the community, and the primacy of intervention rather than receptiveness and presence.

Stress often negatively impacts physical and mental health but it has been suggested that voluntary physical activity may benefit health by reducing some of the effects of stress. The present experiments tested whether voluntary exercise can reduce heart rate, core body temperature and locomotor activity responses to acute (novelty or loud noise) or repeated stress (loud noise). After 6 weeks of running-wheel access, rats exposed to a novel environment had reduced heart rate, core body temperature, and locomotor activity responses compared to rats housed under sedentary conditions. In contrast, none of these measures were different between exercised and sedentary rats following acute 30-min noise exposures, at either 85 or 98 dB. Following 10 weeks of running-wheel access, both groups displayed significant habituation of all these responses to 10 consecutive daily 30-min presentations of 98 dB noise stress. However, the extent of habituation of all three responses was significantly enhanced in exercised compared to sedentary animals on the last exposure to noise. These results suggest that in physically active animals, under some conditions, acute responses to stress exposure may be reduced, and response habituation to repeated stress may be enhanced, which ultimately may reduce the negative and cumulative impact of stress.

Euthanasia and assisted suicide involve taking deliberate action to end or assist in ending the life of another person on compassionate grounds. There is considerable disagreement about the acceptability of these acts and about whether they are ethically distinct from decisions to forgo life-sustaining treatment. Euthanasia and assisted suicide are punishable offences under Canadian criminal law, despite increasing public pressure for a more permissive policy. Some Canadian physicians would be willing to practise euthanasia and assisted suicide if these acts were legal. In practice, physicians must differentiate between respecting competent decisions to forgo treatment, providing appropriate palliative care, and acceeding to a request for euthanasia or assisted suicide. Physicians who believe that euthanasia and assisted suicide should be legally accepted in Canada should pursue their convictions only through legal and democratic means.

Opinions of university students about euthanasia were studied in 4 cities in Pakistan using convenience sampling. A total of 836 students (316 males and 520 females) completed a questionnaire in which euthanasia was defined as deliberate administration of an overdose of a drug by a doctor to relieve pain and suffering of a dying patient at his/her explicit request to end his/her life. Only 25.6% of students agreed that euthanasia should be legalized in Pakistan. The most common reason cited for legalization of euthanasia was to relieve patient's suffering but only when a committee of physicians agreed to recommend it. Students who opposed legalization (74.4%) cited impediments to future medical research as the most common reason, followed by the risk of misuse by physicians or family members. Only 8.9% of students cited religious beliefs as a reason against legalization. There is a need in Pakistan for more debate about euthanasia.
Belgium has recently extended its euthanasia legislation to minors, making it the first legislation in the world that does not specify any age limit. I consider two strands in the opposition to this legislation. First, I identify five arguments in the public debate to the effect that euthanasia for minors is somehow worse than euthanasia for adults--viz, arguments from weightiness, capability of discernment, pressure, sensitivity and sufficient palliative care--and show that these arguments are wanting. Second, there is another position in the public debate that wishes to keep the current age restriction on the books and have ethics boards exercise discretion in euthanasia decisions for minors. I interpret this position on the background of Velleman's 'Against the Right to Die' and show that, although costs remain substantial, it actually can provide some qualified support against extending euthanasia legislation to minors.

In healthy [correction of beglth] subjects, patients with children's cerebral palsy and spinal cord disturbances, the cross-correlation function of the EMG at the initial phase of voluntary movement and at the phase of static voluntary tension revealed some mechanisms maintaining coordinated interrelations among antagonist muscles at different phases. A new approach is suggested for estimation of the electromyogram and for a finer diagnosis of the CNS lesions at different levels.

Physical exercise is a non-pharmacological treatment for affective disorders. The mechanisms of its effects are unknown although some suggest a relationship to synchronization of circadian rhythms. One way to explore mechanisms is to utilize animal models. We previously demonstrated that the diurnal fat sand rat is an advantageous model for studying the interactions between photoperiods and mood. The current study was designed to evaluate the effects of voluntary exercise on activity rhythms and anxiety and depression-like behaviors in sand rats as a step towards better understanding of the underlying mechanisms. Male sand rats were housed in short photoperiod (SP; 5h light/19 h dark) or neutral light (NP; 12h light/12h dark) regimens for 3 weeks and divided into subgroups with or without running wheels. Activity was monitored for 3 additional weeks and then animals were tested in the elevated plus-maze, the forced swim test and the social interaction test. Activity rhythms were enhanced by the running wheels. As hypothesized, voluntary exercise had significant effects on SP animals' anxiety- and depression-like behaviors but not on NP animals. Results are discussed in the context of interactions between physical exercise, circadian rhythms and mood. We suggest that the sand rat model can be used to explore the underlying mechanism of the effects of physical exercise for mood disorders.
Thanks to recent scholarship, Kant is no longer seen as the dogmatic opponent of suicide that he appears to be at first glance. However, some interpreters have recently argued for a Kantian view of the morality of suicide with surprising, even radical, implications. More specifically, they have argued that Kantianism (1) requires that those with dementia or other rationality-eroding conditions end their lives before their condition results in their loss of identity as moral agents and (2) requires subjecting the fully demented or those confronting future dementia to non-voluntary euthanasia. Properly understood, Kant's ethics have neither of these implications (1) wrongly assumes that rational agents' duty of self-preservation entails a duty of self-destruction when they become non-rational, (2) further neglects Kant's distinction between duties to self and duties to others and wrongly assumes that duties can be owed to rational agents only during the time of their existence.
Allowing voluntary use of respirators can provide workers with an added level of comfort and relief from nuisance levels of particulates, gases, or vapors. But misuse can result in illness or injury to the worker. Understanding and following OSHA's guidelines on voluntary use of respirators is one of the many ways you help provide a safe workplace and ensure your employees stay healthy.

In order to accurately interpret experimental data using the topographic body map identified by conventional intracortical microstimulation (ICMS), it is important to know how neurons in each division of the map respond during voluntary movements. Here we systematically investigated neuronal responses in each body representation of the ICMS map during a reach-grasp-retrieval task that involves the movements of multiple body parts. The topographic body map in the primary motor cortex (M1) generally corresponds to functional divisions of voluntary movements; neurons at the recording sites in each body representation with movement thresholds of 10 μA or less were differentially activated during the task, and the timing of responses was consistent with the movements of the body part represented. Moreover, neurons in the digit representation responded differently for the different types of grasping. In addition, the present study showed that neural activity depends on the ICMS current threshold required to elicit body movements and the location of the recording on the cortical surface. In the ventral premotor cortex (PMv), no correlation was found between the response properties of neurons and the body representation in the ICMS map. Neural responses specific to forelimb movements were often observed in the rostral part of PMv, including the lateral bank of the lower arcuate limb, in which ICMS up to 100 μA evoked no detectable movement. These results indicate that the physiological significance of the ICMS-derived maps is different between, and even within, areas M1 and PMv. PMID:27494282

Phytic acid forms insoluble complexes with nutritionally essential minerals, including zinc (Zn). Animal studies show that addition of microbial phytase (P) to low-Zn diets improves Zn status and bone strength. The present study determined the effects of phytase supplementation on bone mineral density (BMD), body composition and voluntary running activity of male rats fed a high phytic acid, low-Zn diet. In a factorial design, rats were assigned to ZnLO (5 mg/kg diet), ZnLO+P (ZnLO diet with 1500 U phytase/kg) or ZnAD (30 mg/kg diet) groups and were divided into voluntary exercise (EX) or sedentary (SED) groups, for 9 weeks. SED rats were significantly heavier from the second week, and no catch-up growth occurred in EX rats. Feed intakes were not different between groups throughout the study. ZnLO animals had decreased food efficiency ratios compared to both phytase-supplemented (ZnLO+P) and Zn-adequate (ZnAD) animals (P<.01 compared to ZnLO). The ZnLO+P and ZnAD rats ran 56-75 km more total distance than ZnLO rats (P<.05), with the ZnLO+P rats running more kilometers per week than the ZnLO rats by Week 6. In vivo DEXA analyses indicate that rats fed phytase-supplemented diets had higher lean body mass (LBM) than those fed ZnLO diets; and that rats fed the Zn-adequate diets had the highest LBM. Body fat (%) was significantly lower in EX rats and was both Zn- and phytase insensitive. Rats fed phytase-supplemented diets had higher bone mineral content (BMC), bone area (BA) and BMD than rats fed ZnLO diets; and in rats fed ZnAD diets these indices were the highest. The dietary effects on BMC, BA and BMD were independent of activity level. We conclude that consuming supplemental dietary phytase or dietary Zn additively enhances Zn status to increase BMD, LBM and voluntary physical activity in rats fed a low-Zn diet. While the findings confirm that bone health is vulnerable to disruption by moderate Zn deficiency in rats, this new data suggests that if dietary Zn is
There is a marked disparity between medical intuitions and philosophical argument about euthanasia. In this paper I argue that the following objections can be raised. First, medical intuitions are against it and this is an area in which judgement and sensitivity are required in that death is a unique and complex process and the patient has many needs including the need to know that others have not discounted his or her worth. Also, part of the moral constitution of a good doctor is a devotion to the protection and preservation of life whatever reasons are produced to dissuade her. Finally, we do not know what the final events of a person's life might hold. PMID:3392719
The death of Freud raises the ethical dilemma about euthanasia. It can be characterized as indirect active euthanasia according to the rule of double effect, or terminal sedation, or palliated death. The primacy of the principle of autonomy over non maleficence, conditioned the physician's attitude toward his patient Freud. The physician assisted death was and remains punishable in western medicine. Therefore, a fundamental tradition was infringed. In contrast, the present study attempts to characterize the final position of Freud himself to his death and called it appropriation of his finitude; he assumes his being-unto-death, that is, he now projects his being not as a being-at-his-end but as a being-unto-end, indicating thereby that he understood that the end always penetrated his whole existence.

The purpose of this study was to compare the effects of fatigue of the plantar flexors on peak torque and voluntary activation in untrained (UT) and resistance-trained (RT) men. Six men with no previous resistance training experience and 8 men with similar histories of chronic resistance training (9.8 ± 5.9 years, 3.8 ± 0.7 days/week) volunteered for this study. Subjects performed isometric maximal voluntary contractions (MVCs) before and immediately after unilateral dynamic isotonic contractions performed at 40% of MVC until volitional exhaustion. Voluntary activation of the plantar flexors was assessed using the interpolated twitch method (ITT) and central activation ratio (CAR). Surface electromyographic (EMG) amplitude of the soleus and medial gastrocnemius (MG) was measured during the MVC. There were significant reductions in MVC torque in both UT and RT groups after the fatiguing exercise (-10.7 ± 6.8%, p < 0.02; -9.1 ± 8.7%, p < 0.02, respectively), with no difference in the number of repetitions performed between groups. The UT and RT men experienced a significant decrease in ITT after the fatiguing exercise bout (-14.2 ± 11.8%, p = 0.03; -7.8 ± 9.3%, p = 0.045, respectively). The UT group experienced a significant decrease in CAR (99.5 ± 0.8% to 91.4 ± 6.4%, p = 0.025) with no change (p > 0.05) in the RT group. There was also a fatigue-induced decrease in normalized EMG amplitude for the soleus and MG muscles in both groups (p < 0.05). However, no differences were determined between groups for ITT, CAR, or EMG. Despite similar reductions in MVC torque postexercise, the UT men had a significant decrease in CAR and experienced nearly twice the decline in ITT than the RT men. These results indicate that the neural adaptations associated with chronic resistance training may lead to less susceptibility to central fatigue as measured by ITT and CAR.

The Belgian law legalizing euthanasia under strict conditions came into effect September 22, 2002. Any physician performing euthanasia has to complete a registration document and to send it within four days to a federal commission whose mission is to verify that the legal conditions were fulfilled. From September 22, 2002 to December 31, 2013, 8.767 documents have been registered and analyzed by this commission. They are described in six reports referred to Parliament. The present paper analyzes the work of this commission and answers the criticisms concerning its quality and its efficiency. The allegations that clandestine euthanasia's escaping any control are performed are also discussed. In conclusion, it appears that the legal obligations concerning the practice of euthanasia in Belgium are fully effective.
This paper reports the findings of an unobtrusive research inquiry investigating the possible use and misuse of Alzheimer's disease in public policy debate on the legalization of euthanasia. The component of the study being reported identified the problematic use of five key metaphors: the Alzheimer metaphor, which in turn was reinforced by three additional metaphors--the epidemic metaphor, the military metaphor, and the predatory thief metaphor; and the euthanasia metaphor. All metaphors were found to be morally loaded and used influentially to stigmatize Alzheimer's disease and mediate public opinion supporting the legalization of euthanasia as an end-of-life 'solution' for people with the disease. It is contended that, in the interests of promoting intellectual honesty and giving proper recognition to the extraordinary complexity of the issue, the problematic use and influence of metaphoric thinking in the public debate about Alzheimer's disease and euthanasia needs to be made transparent, questioned and challenged.

The aim of the study is to explore the medieval concepts on the voluntary death of severely sick people, as they emerge through the endura (endurance) of the heresy of the Cathars in France (twelfth to fourteenth centuries). The endura was the prerequisite act of repentance that would allow the fallen soul to return to heaven. The endura was a necessary act of repentance, after the performance of a ceremonial purification of the soul (consolamentum), and consisted of the patients' voluntary abstention from vital food. The consolamentum and endura could be performed in the final stage of a disease with the consent of the patients or their relatives. The role of the Cathar physician was only to determine the severity of the disease and the forthcoming death of the patient. The physician was not allowed to take steps that would deprive the life of the patient, and the performance of the ritual endura was duty of the spiritual leaders of the community. The modern ethical approach to this subject is dictated by the medieval belief on the salvation of the soul and tries to answer the question of whether the endura could be seen as a medieval concept of a ritual euthanasia or fell within the theological sin of suicide.
Dr Neil Campbell suggests that when patients suffering extremes of protracted pain ask for help to end their lives, their requests should be discounted as made under compulsion. I contend that the doctors concerned should be referred to and then act upon advance directives made by those patients when of sound and calm mind and afflicted by no such intolerable compulsion.

Heart rate (HR) is controlled solely by via cardiac parasympathetic outflow in tetraplegic individuals, who lack supraspinal control of sympathetic outflows and circulating catecholamines but have intact vagal pathways. A high-frequency component (HF; at 0.15-0.40 Hz) of the power spectrum of HR variability and its relative value against total power (HF/Total) were assessed using a wavelet transform to identify cardiac parasympathetic outflow. The relative contribution of cardiac parasympathetic and sympathetic outflows to controlling HR was estimated by comparing the HF/Total-HR relationship between age-matched tetraplegic and normal men. Six tetraplegic men with complete cervical spinal cord injury performed static arm exercise at 35% of the maximal voluntary contraction until exhaustion. Although resting cardiac output and arterial blood pressure were lower in tetraplegic than normal subjects, HR, HF, and HF/Total were not statistically different between the two groups. When tetraplegic subjects developed the same force during exercise as normal subjects, HF and HF/Total decreased to 67-90% of the preexercise control and gradually recovered 1.5 min after exercise. The amount and time course of the changes in HF/Total during and after exercise coincided well between both groups. In contrast, the increase in HR at the start of exercise was blunted in tetraplegic compared with normal subjects, and the HR recovery following exercise was also delayed. It is likely that, although the withdrawal response of cardiac parasympathetic outflow is preserved in tetraplegic subjects, sympathetic decentralization impairs the rapid acceleration of HR at the onset of exercise and the rapid deceleration following exercise.

In rodents, the disruption of social-rearing conditions before normal weaning induces emotional behavioral abnormalities, such as anxiety, motor activity dysregulation, and stress vulnerability. The beneficial effects of exercise after normal weaning on emotional regulation have been well documented. However, effects of exercise before normal weaning on emotion have not been reported. We examined whether voluntary wheel running (R) during social isolation after early weaning (early weaning/isolation; EI) from postnatal day (PD) 14-30 could prevent EI-induced emotional behavioral abnormalities in Sprague-Dawley rats. Compared with control rats reared with their dam and siblings until PD30, rats performed R during EI (EI+R) and EI rats demonstrated greater locomotion and lower grooming activity in the open-field test (OFT) during the juvenile period. Juvenile EI ± R rats showed greater learned helplessness (LH) after exposure to inescapable stress (IS; electric foot shock) than IS-exposed control and EI rats. In contrast, EI rats showed increased locomotion in the OFT and LH after exposure to IS compared with control rats during adulthood; this was not observed in EI ± R rats. Both EI and EI ± R rats exhibited greater rearing activity in the OFT than controls during adulthood. EI did not increase anxiety in the OFT and elevated plus-maze. These results suggested that R during EI until normal weaning prevented some of the EI-induced behavioral abnormalities, including hyperlocomotor activity and greater LH, during adulthood but not in the juvenile period.
Euthanasia has for a long time been the object of very lively discussions in Poland. This article contains the views of scientists from various fields of science, especially medical doctors of different specialities. All of them have very serious objections to euthanasia and are against its practical application not only from the medical point of view but first of all for purely humanitarian reasons. Polish penal law regards murder on request as delictum sui generis, i.e., as a kind of privileged crime as compared with common murder. Article No. 150 of the Polish penal law demands two features to characterise euthanasia: (1) the delinquent must act on grounds of compassion towards his victim, and (2) on the victim's request. The patient must be in such a state that gives reason for compassion. The request to shorten somebody's life must be very distinct, direct, firm, conscious and convincing. Perosns under age, mentally defective or unconscious cannot express such a wich. Polish penal law punishes with utmost severtity perpetrators of active euthanasia even in such cases in which the delinquent was moved by the most noble feelings. Only when it comes to penalty is distinction made between such a delinquent and a common murderer.

Studied the relationship of attitudes toward euthanasia to death fears and demographic variables in a sample of 100 adults. Found the strongest predictors of euthanasia attitude were age and amount of education. Suggests individuals who are more experienced with life and death have a more positive attitude toward euthanasia. (Author)

Based on cross-cultural studies of euthanasia and abortion, we hypothesized that attitudes toward euthanasia and abortion were socioculturally determined. Using a 2 x 2 factorial design, we examined the effects of culture (America and China) and type of death (infanticide and geronticide). We found that students from the American culture were less likely to favor infanticide than those from the Chinese culture, and that students from the People's Republic of China believed infanticide to be more common and more prevalent than geronticide in Chinese society. Finally, we found that education, judgment of population density, and traditional family values were related to attitudes toward euthanasia, abortion, and female infanticide in the Chinese, but not in the American, culture.

Background Euthanasia became legal in Belgium in 2002. Physicians must adhere to legal due care requirements when performing euthanasia; for example, consulting a second physician and reporting each euthanasia case to the Federal Review Committee. Aim To study the adherence and non-adherence of GPs to legal due care requirements for euthanasia among patients dying at home in Belgium and to explore possible reasons for non-adherence. Design of study Large scale, retrospective study. Setting General practice in Belgium. Method A retrospective mortality study was performed in 2005–2006 using the nationwide Belgian Sentinel Network of General Practitioners. Each week GPs reported medical end-of-life decisions taken in all non-sudden deaths of patients in their practice. GP interviews were conducted for each euthanasia case occurring at home. Results Interviews were conducted for nine of the 11 identified euthanasia cases. Requirements concerning the patient's medical condition were met in all cases. Procedural requirements such as consultation of a second physician were sometimes ignored. Euthanasia cases were least often reported (n = 4) when the physician did not regard the decision as euthanasia, when only opioids were used to perform euthanasia, or when no second physician was consulted. Factors that may contribute to explaining non-adherence to the euthanasia law included: being unaware of which practices are considered to be euthanasia; insufficient knowledge of the euthanasia law; and the fact that certain procedures are deemed burdensome. Conclusion Substantive legal due care requirements for euthanasia concerning the patient's request for euthanasia and medical situation were almost always met by GPs in euthanasia cases. Procedural consultation and reporting requirements were not always met. PMID:20353662

Despite the potential of repetitive transcranial magnetic stimulation (rTMS) to improve performances in patients suffering from motor neuronal afflictions, its effect on motor performance enhancement in healthy subjects during a specific sport task is still unknown. We hypothesized that after an intermittent theta burst (iTBS) treatment, performance during the Wingate Anaerobic Test (WAnT) will increase and supraspinal fatigue following the exercise will be lower in comparison to a control treatment. Ten subjects participated in two randomized experiments consisting of a WAnT 5 min after either an iTBS or a control treatment. We determined voluntary activation (VA) of the right knee extensors with TMS (VATMS) and with peripheral nerve stimulation (VAPNS) of the femoral nerve, before and after the WAnT. T-tests were applied to the WAnT results and a two way within subject ANOVA was applied to VA results. The iTBS treatment increased the peak power and the maximum pedalling cadence and suppressed the reduction of VATMS following the WAnT compared to the control treatment. No behavioral changes related to fatigue (mean power and fatigue index) were observed. These results indicate for the first time that iTBS could be used as a potential intervention to improve anaerobic performance in a sport specific task.

This study aimed to investigate whether the fatigue induced by sustained motor task in the jaw elevator muscles differed between healthy subjects and patients with temporomandibular disorder (TMD). Fifteen patients with TMD and thirteen age- and sex-matched healthy controls performed a fatigue test consisting of sustained clenching contractions at 30% maximal voluntary clenching intensity until test failure (the criterion for terminating the fatigue test was when the biting force decreased by 10% or more from the target force consecutively for >3 s). The pre- and post-maximal bite forces (MBFs) were measured. Surface electromyographic signals were recorded from the superficial masseter muscles and anterior temporal muscles bilaterally, and the median frequency at the beginning, middle and end of the fatigue test was calculated. The duration of the fatigue test was also quantified. Both pre- and post-MBFs were lower in patients with TMD than in controls (P < 0·01). No significant difference was found in the percentage change in MBF between groups. The duration of the fatigue test in TMD patients was significantly shorter than that of the controls (P < 0·05). Our results suggest that, compared to healthy subjects, patients with TMD become more easily fatigued, but the electromyographic activation process during the fatigue test is similar between healthy subjects and patients with TMD. However, the mechanisms involved in this process remain unclear, and further research is warranted.

This pilot study sought to examine the exercise behavior and preferences among adolescent and young adult (AYA) hematopoietic stem cell transplant (HSCT) recipients. Eighteen patients aged 19 to 25 years were recruited to engage in unsupervised exercise activities lasting at least 60 minutes/week during hospitalization for HSCT. Enrolled patients had access to standard exercise activities (walking, resistance training, and basketball) and active video gaming equipment. Physical function (6-Minute Walk Test and Timed-Up-and-Go test) and quality of life (Behavioral, Affective, and Somatic Experiences Scale) were assessed at different time points during admission. Participants exercised an average of 76% of the days during admission and spent an average of 36.5 minutes per day exercising. The Nintendo Wii was the preferred active video gaming equipment, but standard exercises accounted for 73% of all exercise time. Neither functional capacity nor quality of life improved. Results suggest that AYAs voluntarily exercise during HSCT admission, prefer to use standard exercise activities, and may require supervision in order to derive maximum benefits from their efforts. These results provide guidance for developing rehabilitation interventions for AYA HSCT recipients.

This study presents a method based on empirical mode decomposition (EMD) and a spatial template-based matching approach to extract sensorimotor oscillatory activities from multi-channel magnetoencephalographic (MEG) measurements during right index finger lifting. The longitudinal gradiometer of the sensor unit which presents most prominent SEF was selected on which each single-trial recording was decomposed into a set of intrinsic mode functions (IMFs). The correlation between each IMF of the selected channel and raw data on other channels were created and represented as a spatial map. The sensorimotor-related IMFs with corresponding correlational spatial map exhibiting large values on primary sensorimotor area (SMI) were selected via spatial-template matching process. Trial-specific alpha and beta bands were determined in sensorimotor-related oscillatory activities using a two-spectrum comparison between the spectra obtained from baseline period (-4 to -3 s) and movement-onset period (-0.5 to 0.5 s). Sensorimotor-related oscillatory activities were filtered within the trial-specific frequency bands to resolve task-related oscillatory activities. Results demonstrated that the optimal phase and amplitude information were preserved not only for alpha suppression (event-related desynchronization) and beta rebound (event-related synchronization) but also for profound analysis of subtle dynamics across trials. The retention of high SNR in the extracted oscillatory activities allow various methods of source estimation that can be applied to study the intricate brain dynamics of motor control mechanisms. The present study enables the possibility of investigating cortical pathophysiology of movement disorder on a trial-by-trial basis which also permits an effective alternative for participants or patients who can not endure lengthy procedures or are incapable of sustaining long experiments.

Voluntary carriage, which occurs when a pipeline transports gas for another party without taking title to the gas, rose from 18.6 to 19.6% of total sales and deliveries of natural gas between 1982 and 1983. This continues a 10-year trend of voluntary carriage increasing its share of the gas market. Transport for gas distributors and end users rose from 360 Bcf in 1982 to 585 Bcf in 1983 despite a 12% drop in total sales and deliveries on the interstate pipeline systems in the study sample. Total revenues received for carriage totalled $1.3 billion in 1983, 10.4% of total pipeline revenues net of purchased gas costs. These figures indicate a growing role for transportation in the pipeline business. 3 figures, 1 table.

Chronic alcohol (ethanol) intake alters fundamental properties of the circadian clock. While previous studies have reported significant alterations in free-running circadian period during chronic ethanol access, these effects are typically subtle and appear to require high levels of intake. In the present study we examined the effects of long-term voluntary ethanol intake on ethanol consumption and free-running circadian period in male and female, selectively bred ethanol-preferring P and HAD2 rats. In light of previous reports that intermittent access can result in escalated ethanol intake, an initial 2-week water-only baseline was followed by either continuous or intermittent ethanol access (i.e., alternating 15-day epochs of ethanol access and ethanol deprivation) in separate groups of rats. Thus, animals were exposed to either 135 days of continuous ethanol access or to five 15-day access periods alternating with four 15-day periods of ethanol deprivation. Animals were maintained individually in running-wheel cages under continuous darkness throughout the experiment to allow monitoring of free-running activity and drinking rhythms, and 10% (v/v) ethanol and plain water were available continuously via separate drinking tubes during ethanol access. While there were no initial sex differences in ethanol drinking, ethanol preference increased progressively in male P and HAD2 rats under both continuous and intermittent-access conditions, and eventually exceeded that seen in females. Free-running period shortened during the initial ethanol-access epoch in all groups, but the persistence of this effect showed complex dependence on sex, breeding line, and ethanol-access schedule. Finally, while females of both breeding lines displayed higher levels of locomotor activity than males, there was little evidence for modulation of activity level by ethanol access. These results are consistent with previous findings that chronic ethanol intake alters free-running circadian

This article gives an overview of the nursing ethics arguments on euthanasia in general, and on nurses' involvement in euthanasia in particular, through an argument-based literature review. An in-depth study of these arguments in this literature will enable nurses to engage in the euthanasia debate. We critically appraised 41 publications published between January 1987 and June 2007. Nursing ethics arguments on (nurses' involvement in) euthanasia are guided primarily by the principles of respect for autonomy, nonmaleficence, beneficence and justice. Ethical arguments related to the nursing profession are described. From a care perspective, we discuss arguments that evaluate to what degree euthanasia can be considered positively or negatively as a form of good nursing care. Most arguments in the principle-, profession- and care-orientated approaches to nursing ethics are used both pro and contra euthanasia in general, and nurses' involvement in euthanasia in particular.
Despite claims that the government is reducing the amount of environmental regulation, the sheer amount of regulatory language has actually increased yearly. Yet based on media reports and citizen claims, pollution appears to go unchecked. Citizens condemn a perceived lack of government regulation of industrial pollution, while industries find themselves mired in increasingly complex regulatory programs that are sometimes far removed from real world situations. US Environmental Protection Agency (EPA) decision-makers have responded to these concerns by designing regulatory programs that abandon traditional command-and-control regulatory schemes as ill-suited to today`s pollution problems and the interests of these stakeholders. This paper analyzes the use of voluntary pollution control programs in place of command-and-control regulation. It is proposed that voluntary programs may serve as carrots to entice regulated entities to reduce pollution, but that there are a number of hurdles to their effective implementation that preclude them from being embraced as effective environmental regulatory tools. This paper reviews why agencies have moved from command-and-control regulation and examines current voluntary pollution control programs. This paper also contemplates the future of such programs.

In Italy, the conditions under which euthanasia of small pets is justified are only partially regulated by law n. 281/1991, article 2 n. 6 and 9, by the later Ministry Circular n. 9 made on 10/03/1992 and by law n. 189/2004. Law n. 281/1991, besides delegating the job of birth control in cat and dog populations to the regions, has made it statutory that stray dogs may only be euthanised when they are 'seriously or incurably ill or proven to be dangerous'. The Ministry Circular underlines the fact that 'euthanasia of dogs is prohibited except in special justified cases'. On the other hand, due to the legal classification of animals as property, the owner has the right of ownership over his animal so that he can sell it and kill it (ius vitae ac necis). In this view a request for euthanasia is licit, whatever the animal's state of health may be. The authors feel that further legislation to regulate the question more completely would be opportune and thus they analyse the problems of legal-ethics and public health that a veterinarian faces when carrying out euthanasia, also bearing in mind the laws and codes of professional ethics. They suggest possible solutions which could be adopted by the competent authorities.

There is currently widespread concern among researchers in debating questions that generate ethical conflicts within the scope of health care geared to the human being in the terminal phase, especially euthanasia, dysthanasia and orthothanasia. This study sought to characterize the scientific production at the national level on euthanasia, dysthanasia and orthothanasia. It involves an integrative review of the literature. The study universe consisted of 41 publications related to the theme in question by means of a survey conducted online in the Virtual Health Library in the Capes Portal and in the Bioethical Magazine. Of these, 25 articles comprised the sample taking into consideration the established inclusion and exclusion criteria. Data collection occurred in March 2013, by means of an instrument containing information pertinent to the proposed objective. The key words used were euthanasia, dysthanasia and orthothanasia. With respect to the focus of the publications, three themes emerged: Theme I - Euthanasia; Theme II - Dysthanasia and Theme III - Orthothanasia. The studies analyzed reflected the current concern in terms of ethical dilemmas concerning care of the human being in the end of life phase. Thus, it is hoped that this research can contribute to bolster the critical reading with respect to the theme.

50 years ago within a so-called "euthanasia" action programme several killing institutions were founded, in which nearly 100,000 patients suffering from mental diseases were brought to death. At the instance of the Bernburg mental hospital the involvements of the political psychiatry and the murdering mechanism are described.

Introduction: The topic of euthanasia has induced differences not only among professionals in the medical fraternity but also in other fields as well. The dying process is being lengthened by the new state of art technologies erupting as such higher pace, and it is at the expense of standard quality of life and of a gracious death. Aim: To study the awareness and attitude toward euthanasia among select professionals in Delhi. Methodology: It was a questionnaire-based descriptive cross-sectional study. The study population included doctors, nurses, judges, lawyers, journalist, and social activists of Delhi. Tool included a sociodemographic questionnaire, two questions to know awareness regarding euthanasia and a modified euthanasia attitude scale used to measure attitude toward euthanasia. Data were analyzed using Stata 11.2. Results: Through our study, it is evident that professionals who participated in the study (judges, advocates, doctors, nurses, journalists, and social activists) in Delhi were familiar with the term euthanasia. No significant difference was seen in the attitude of professionals of different age group and sex toward euthanasia. Conclusion: Through this study, it is found that judiciary group most strongly endorsed euthanasia. The attitude of doctors was elicited from mixed group with doctors belonging to different specialties. Oncologists are not in favor of any form of euthanasia. However, doctors from other specialties did support euthanasia. PMID:27803572

Do animals evolve (coadapt) to choose diets that positively affect their performance abilities? We addressed this question from a microevolutionary perspective by examining preference for Western diet (WD: high in fat and sugar, but lower in protein) versus standard rodent chow in adults of both sexes from 4 lines of mice selectively bred for high levels of voluntary wheel running (High Runner or HR lines) and 4 non-selected control (C) lines. We also assessed whether food preference or substitution affects physical activity (wheel running and/or spontaneous physical activity [SPA] in the attached home cages). In experiment 1 (generation 56), mice were given 6days of wheel acclimation (as is used routinely to pick breeders in the selection experiment) prior to a 2-day food choice trial. In experiment 2 (generation 56), 17days of wheel acclimation allowed mice to reach a stable level of daily running, followed by a 7-day food-choice trial. In experiment 3 (generation 58), mice had 6days of wheel acclimation with standard chow, after which half were switched to WD for two days. In experiment 1, WD was highly preferred by all mice, with somewhat greater preference in male C mice. In experiment 2, wheel running increased and SPA decreased continuously for the first 14days of adult wheel testing, followed by 3-day plateaus in both. During the subsequent 7-day food choice trial, HR mice of both sexes preferred WD significantly more than did C mice; moreover, wheel running increased in all groups except males from C lines, with the increase being significantly greater in HR than C, while SPA declined further in all groups. In experiment 3, the effect of being switched to WD depended on both linetype and sex. On standard chow, only HR females showed a significant change in wheel running during nights 7+8, increasing by 10%. In contrast, when switched to WD, C females (+28%), HR females (+33%), and HR males (+10%) all significantly increased their daily wheel

In this study we compared rat (n = 16) responses to euthanasia with either gradual-fill CO(2) or rapid induction argon gas by evaluating the animals' heart rate via radiotelemetry, behavior, and vocalizations. We also evaluated the histologic effects of the gases. Rats were placed in an open test chamber 24 h before the start of the experiment. During baseline tests, rats were exposed to oxygen to evaluate the effects of the noise and movement of gas entering the chamber; 1 wk later, rats were euthanized by gas displacement with either 10%/min CO(2) or 50%/min argon gas. Rats tended to have higher heart rats and were more active during the baseline test, but these parameters were normal before the euthanasia experiment, suggesting that the rats had acclimated to the equipment. Heart rate, behavior, and ultrasonic vocalizations were recorded for 2 min after gas introduction in both groups. All rats appeared conscious throughout the test interval. The heart rates of rats exposed to argon did not change, whereas those of rats exposed to CO(2) declined significantly. Unlike those exposed to CO(2), rats euthanized with argon gas gasped and demonstrated seizure-like activity. There were no differences in the pulmonary lesions resulting from death by either gas. Our results suggest that argon as a sole euthanasia agent is aversive to rats. CO(2) using a 10%/min displacement may be less aversive than more rapid displacements. Future research investigating methods of euthanasia should allow sufficient time for the rats to acclimate to the test apparatus.

Suicide amongst the very old is an important public health issue. Little is known about why older people may express a wish to die or request euthanasia and how such thoughts may intersect with suicide attempts. Palliative care models promote best care as holistic and relieving suffering without hastening death in severely ill patients; but what of those old people who are tired of living and may have chronic symptoms, disability, and reduced quality of life? Two cases of older people who attempted suicide but expressed a preference for euthanasia were it legal are presented in order to illustrate the complexity underlying such requests. The absence of a mood or anxiety disorder underpinning their wishes to die further emphasises the importance of understanding the individual's narrative and the role of a formulation in guiding broad biopsychosocial approaches to management.

Death has preoccupied humanity since before the dawn of civilization. As a multidimensional and moral problem, the end of life has concerned different civilizations, and different approaches to euthanasia, or "good death," have been developed in each culture. In Greece, there is a long record of the culture's evolving attitudes toward death and euthanasia.A more widespread knowledge of the views and traditions surrounding the act of euthanasia can contribute to a better understanding of the controversies surrounding modern attitudes and practice.

Study Objectives: Animal sleep deprivation (SDEP), in contrast to human SDEP, is involuntary and involves repeated exposure to aversive stimuli including the inability of the animal to control the waking stimulus. Therefore, we explored intracranial self-stimulation (ICSS), an operant behavior, as a method for voluntary SDEP in rodents. Methods: Male Sprague-Dawley rats were implanted with electroencephalography/electromyography (EEG/EMG) recording electrodes and a unilateral bipolar electrode into the lateral hypothalamus. Rats were allowed to self-stimulate, or underwent gentle handling-induced SDEP (GH-SDEP), during the first 6 h of the light phase, after which they were allowed to sleep. Other rats performed the 6 h ICSS and 1 w later were subjected to 6 h of noncontingent stimulation (NCS). During NCS the individual stimulation patterns recorded during ICSS were replayed. Results: After GH-SDEP, ICSS, or NCS, time in nonrapid eye movement (NREM) sleep and rapid eye movement (REM) sleep increased. Further, in the 24 h after SDEP, rats recovered all of the REM sleep lost during SDEP, but only 75% to 80% of the NREM sleep lost, regardless of the SDEP method. The magnitude of EEG slow wave responses occurring during NREM sleep also increased after SDEP treatments. However, NREM sleep EEG slow wave activity (SWA) responses were attenuated following ICSS, compared to GH-SDEP and NCS. Conclusions: We conclude that ICSS and NCS can be used to sleep deprive rats. Changes in rebound NREM sleep EEG SWA occurring after ICSS, NCS, and GH-SDEP suggest that nonspecific effects of the SDEP procedure differentially affect recovery sleep phenotypes.

This article presents the attitudes of nurses towards three issues concerning their role in euthanasia and physician-assisted suicide. A questionnaire survey was conducted with 1509 nurses who were employed in hospitals, home care organizations and nursing homes. The study was conducted in the Netherlands between January 2001 and August 2004. The results show that less than half (45%) of nurses would be willing to serve on committees reviewing cases of euthanasia and physician-assisted suicide. More than half of the nurses (58.2%) found it too far-reaching to oblige physicians to consult a nurse in the decision-making process. The majority of the nurses stated that preparing euthanatics (62.9%) and inserting an infusion needle to administer the euthanatics (54.1%) should not be accepted as nursing tasks. The findings are discussed in the context of common practices and policies in the Netherlands, and a recommendation is made not to include these three issues in new regulations on the role of nurses in euthanasia and physician-assisted suicide.

Objectives: To discover what factors affect lay people's judgments of the acceptability of physician assisted suicide and euthanasia and how these factors interact. Design: Participants rated the acceptability of either physician assisted suicide or euthanasia for 72 patient vignettes with a five factor design—that is, all combinations of patient's age (three levels); curability of illness (two levels); degree of suffering (two levels); patient's mental status (two levels), and extent of patient's requests for the procedure (three levels). Participants: Convenience sample of 66 young adults, 62 middle aged adults, and 66 older adults living in western France. Main measurements: In accordance with the functional theory of cognition of N H Anderson, main effects, and interactions among patient factors and participants' characteristics were investigated by means of both graphs and ANOVA. Results: Patient requests were the most potent determinant of acceptability. Euthanasia was generally less acceptable than physician assisted suicide, but this difference disappeared when requests were repetitive. As their own age increased, participants placed more weight on patient age as a criterion of acceptability. Conclusions: People's judgments concur with legislation to require a repetition of patients' requests for a life ending act. Younger people, who frequently are decision makers for elderly relatives, place less emphasis on patient's age itself than do older people. PMID:14662811

Many physicians and patients do not realize that it is legally and medically possible to donate organs after euthanasia. The combination of euthanasia and organ donation is not a common practice, often limited by the patient's underlying pathology, but nevertheless has been performed >40 times in Belgium and the Netherlands since 2005. In anticipation of patients' requests for organ donation after euthanasia and contributing to awareness of the possibility of this combination among general practitioners and medical specialists, the Maastricht University Medical Center and the Erasmus University Medical Center Rotterdam have developed a multidisciplinary practical manual in which the organizational steps regarding this combined procedure are described and explained. This practical manual lists the various criteria to fulfill and the rules and regulations the different stakeholders involved need to comply with to meet all due diligence requirements. Although an ethicist was involved in writing this paper, this report is not specifically meant to comprehensively address the ethical issues surrounding the topic. This paper is focused on the operational aspects of the protocol.

CO2 euthanasia is used widely for small laboratory animals, such as rodents. A common necessity in many animal research facilities is to euthanize mice in sequential batches. We assessed the effects of several variables on the time it took for CO2 to dissipate within a chamber. Using standard euthanasia time, changes in flow rate were compared between a slow 15% fill rate for 7 min, and a slow 15% followed by a rapid 50% filling for a total of 5 min. Additional variables assessed included the effects of opening the lid after the completion of chamber filling, turning the chamber over after completion of filling, and the use and removal of a cage from within the chamber. For all trials, CO2 levels in the chambers peaked between 50% and 80%. After the gas was turned off, the concentration of CO2 dropped to below 10% CO2 within 2 min, except when the lid was left on the chamber, where concentration levels remained above 10% after 20 min. CO2 dissipation was significantly faster when the chamber was turned upside down after filling. Significant interaction effects occurred among the factors of cage presence within the chamber, flow rate, and chamber position. Only leaving the lid on the chamber had any practical implication for delaying CO2 dissipation. We recommend that users allow 2 min for CO2 to clear from the chamber before subsequent euthanasia procedures, unless the chamber is manipulated to increase the dissipation rate. PMID:25199098

The aim of the study conducted upon completion of obligatory palliative medicine courses among 588 medical students at two universities was to compare their attitudes toward euthanasia. Four hundred ninety-two (84.97 %) students were Catholics; 69 (11.73 %) declared they would practice euthanasia, 303 (51.53 %) would not, and 216 students (36.73 %) were not sure. The idea of euthanasia legalisation was supported by 174 (29.59 %) respondents, opposed by 277 (47.11 %), and 137 (23.30 %) were undecided. Five hundred fifty-six (94.56 %) students did not change their attitudes toward euthanasia after palliative medicine courses. Students from the two universities were found to have different opinions on practicing euthanasia, euthanasia law and possible abuse which might follow euthanasia legalisation, but they shared similar views on the choice of euthanasia if they themselves were incurably ill and the legalisation of euthanasia. Gender and religion influenced students' answers. Differences observed between medical students at the two universities might be related to gender and cultural differences.
Voluntary international standards for mining machinery may gradually replace many national regulations. The days of establishing voluntary standards nation by nation, inhibiting the important flow of international trade, could be numbered. This does not mean that nations will cease domestic regulatory activities within their boundaries, but rulemaking will pay considerable attention to voluntary international standards and will likely strive for compatibility with voluntary international standards. International standards setting bodies are developing standards for machine safety. When these standards are complete and adopted, some nations will require machinery to comport with them. International commerce in products that do not conform to these voluntary international standards may be discouraged.
Firms play a key role in pollution abatement and control by engaging in beyond-compliance actions without the force of law in voluntary programs. This study examines the effectiveness of a bilateral voluntary agreement, one type of voluntary programs, negotiated between the U.S. Environmental Protection Agency (EPA) and the pressure-treated wood industry to phase-out the use of chromated copper arsenate (CCA), a poisonous arsenic compound. Arsenic is ranked number one on the EPA's priority list of hazardous substances. Unlike a majority of earlier studies on voluntary programs, dynamic panel estimation and structural break analysis show that while a technological innovation in semiconductors is associated with arsenic use increases, the CCA voluntary agreement is associated with a reduction in arsenic use to levels not seen since the 1920s. A voluntary ban in arsenic acid by pesticide manufacturers in the agriculture sector has also contributed to arsenic reductions. Furthermore, the results suggest that environmental activism has played a role in curbing arsenic use. Increasing stakeholder pressures, as measured by membership in the Sierra Club, improves voluntary agreement effectiveness.

In response to the general prohibition of euthanasia and assisted suicide, some right-to-die activists have developed non-medical methods to covertly hasten death. One such method is a "debreather," a closed system breathing device that laypersons can use to induce hypoxia for persons seeking euthanasia or assisted suicide. This article presents…

Veterinarians are more likely to experience mood disorders and suicide than other occupational groups (Fritschi, Morrison, Shirangi & Day, 2009; Platt, Hawton, Simkin, & Mellanby, 2010). The performance of euthanasia has been implicated as contributing determinately to the prevalence of suicide risk and psychological distress in veterinarians (Bartram & Baldwin, 2008, 2010). In contrast, the application of psychological approaches would suggest a possible protective role for euthanasia administration. This paper is the first to investigate the association between euthanasia-administration frequency and depressed mood and suicide risk. A cross-sectional survey sampled 540 Australia-registered veterinarians (63.8% women), ranging in age from 23 to 74. Results revealed that the administration of objectionable euthanasia (i.e., euthanasia that the veterinarian disagreed with) was not related to our mental health variables. In contrast, overall euthanasia frequency had a weak positive linear relationship with depression. Moreover, overall euthanasia frequency moderated the impact of depression on suicide risk. The nature of this moderation suggested that average frequency per week of performing euthanasia attenuated the relationship between depressed mood and suicide risk. The implications of these findings and directions for further research are discussed.

This study explores expressed wishes and requests for euthanasia (i.e. administration of lethal drugs at the explicit request of the patient), and incidence of end-of-life decisions with possible life-shortening effects (ELDs) in advanced lung cancer patients in Flanders, Belgium. We performed a prospective, longitudinal, observational study of a consecutive sample of advanced lung cancer patients and selected those who died within 18 months of diagnosis. Immediately after death, the pulmonologist/oncologist and general practitioner (GP) of the patient filled in a questionnaire. Information was available for 105 out of 115 deaths. According to the specialist or GP, one in five patients had expressed a wish for euthanasia; and three in four of these had made an explicit and repeated request. One in two of these received euthanasia. Of the patients who had expressed a wish for euthanasia but had not made an explicit and repeated request, none received euthanasia. Patients with a palliative treatment goal at inclusion were more likely to receive euthanasia. Death was preceded by an ELD in 62.9% of patients. To conclude, advanced lung cancer patients who expressed a euthanasia wish were often determined. Euthanasia was performed significantly more among patients whose treatment goal after diagnosis was exclusively palliative.
In recent years, palliative care and related organizations have increasingly adopted a stance of "studied neutrality" on the question of whether euthanasia should be legalized as a bona fide medical regimen in palliative care contexts. This stance, however, has attracted criticism from both opponents and proponents of euthanasia. Pro-euthanasia activists see the stance as an official position of indecision that is fundamentally disrespectful of a patient's right to "choose death" when life has become unbearable. Some palliative care constituents, in turn, are opposed to the stance, contending that it reflects an attitude of "going soft" on euthanasia and as weakening the political resistance that has hitherto been successful in preventing euthanasia from becoming more widely legalized. In this article, attention is given to examining critically the notion and possible unintended consequences of adopting a stance of studied neutrality on euthanasia in palliative care. It is argued that although palliative care and related organizations have an obvious stake in the outcome of the euthanasia debate, it is neither unreasonable nor inconsistent for such organizations to be unwilling to take a definitive stance on the issue. It is further contended that, given the long-standing tenets of palliative care, palliative care organizations have both a right and a responsibility to defend the integrity of the principles and practice of palliative care and to resist demands for euthanasia to be positioned either as an integral part or logical extension of palliative care.

Abstract Background Little is known about how often physicians are formally accused of hastening patient deaths while practicing palliative care. Methods We conducted an Internet-based survey on a random 50% sample of physician-members of a national hospice and palliative medicine society. Results The final sample consisted of 663 physicians (response rate 53%). Over half of the respondents had had at least one experience in the last 5 years in which a patient's family, another physician, or another health care professional had characterized palliative treatments as being euthanasia, murder, or killing. One in four stated that at least one friend or family member, or a patient had similarly characterized their treatments. Respondents rated palliative sedation and stopping artificial hydration/nutrition as treatments most likely to be misconstrued as euthanasia. Overall, 25 physicians (4%) had been formally investigated for hastening a patient's death when that had not been their intention—13 while using opiates for symptom relief and six for using medications while discontinuing mechanical ventilation. In eight (32%) cases, another member of the health care team had initiated the charges. At the time of the survey, none had been found guilty, but they reported experiencing substantial anger and worry. Conclusions Commonly used palliative care practices continue to be misconstrued as euthanasia or murder, despite this not being the intention of the treating physician. Further efforts are needed to explain to the health care community and the public that treatments often used to relieve patient suffering at the end of life are ethical and legal. PMID:22401355

Euthanasia is a double-edged sword in veterinary medicine. It is a powerful and ultimately the most powerful tool for ending the pain and suffering. Demand for its use for client convenience is morally reprehensible and creates major moral stress for ethically conscious practitioners. But equally reprehensible and stressful to veterinarians is the failure to use it when an animal faces only misery, pain, distress, and suffering. Finding the correct path through this minefield may well be the most important ethical task facing the conscientious veterinarian.

Both voluntary and involuntary movements activate sensors in the muscles, skin, tendon and joints. As limb movement can result from a mixture of spinal reflexes and voluntary motor commands, the cortical centres underlying conscious proprioception might either aggregate or separate the sensory inputs generated by voluntary movements from those generated by involuntary movements such as spinal reflexes. We addressed whether healthy volunteers could perceive the contribution of a spinal reflex during movements that combined both reflexive and voluntary contributions. Volunteers reported the reflexive contribution in leg movements that were partly driven by the knee-jerk reflex induced by a patellar tendon tap and partly by voluntary motor control. In one condition, participants were instructed to kick back in response to a tendon tap. The results were compared to reflexes in a resting baseline condition without voluntary movement. In a further condition, participants were instructed to kick forwards after a tap. Volunteers reported the perceived reflex contribution by repositioning the leg to the perceived maximum displacement to which the reflex moved the leg after each tendon tap. In the resting baseline condition, the reflex was accurately perceived. We found a near-unity slope of linear regressions of perceived on actual reflexive displacement. Both the slope value and the quality of regression fit in individual volunteers were significantly reduced when volunteers were instructed to generate voluntary backward kicks as soon as they detected the tap. In the kick forward condition, kinematic analysis showed continuity of reflex and voluntary movements, but the reflex contribution could be estimated from electromyography (EMG) recording on each trial. Again, participants' judgements of reflexes showed a poor relation to reflex EMG, in contrast to the baseline condition. In sum, we show that reflexes can be accurately perceived from afferent information. However
Background The Netherlands is one of the few countries where euthanasia is legal under strict conditions. This study investigates whether Dutch newspaper articles use the term ‘euthanasia’ according to the legal definition and determines what arguments for and against euthanasia they contain. Methods We did an electronic search of seven Dutch national newspapers between January 2009 and May 2010 and conducted a content analysis. Results Of the 284 articles containing the term ‘euthanasia’, 24% referred to practices outside the scope of the law, mostly relating to the forgoing of life-prolonging treatments and assistance in suicide by others than physicians. Of the articles with euthanasia as the main topic, 36% described euthanasia in the context of a terminally ill patient, 24% for older persons, 16% for persons with dementia, and 9% for persons with a psychiatric disorder. The most frequent arguments for euthanasia included the importance of self-determination and the fact that euthanasia contributes to a good death. The most frequent arguments opposing euthanasia were that suffering should instead be alleviated by better care, that providing euthanasia can be disturbing, and that society should protect the vulnerable. Conclusions Of the newspaper articles, 24% uses the term ‘euthanasia’ for practices that are outside the scope of the euthanasia law. Typically, the more unusual cases are discussed. This might lead to misunderstandings between citizens and physicians. Despite the Dutch legalisation of euthanasia, the debate about its acceptability and boundaries is ongoing and both sides of the debate are clearly represented. PMID:23497284

Since 2002, Belgium has had a national law legalising euthanasia. The law prescribes several substantive due care requirements and two procedural due care requirements, i.e. consultation with an independent physician and reporting of euthanasia to a Federal Control Committee. A large discrepancy in reporting rates between the Dutch-speaking (Flanders) and the French-speaking (Wallonia) parts of Belgium has led to speculation about cultural differences affecting the practice of euthanasia in both regions. Using Belgian data from the European Values Study conducted in 2008 among a representative sample of the general public and data from a large-scale mail questionnaire survey on euthanasia of 480 physicians from Flanders and 305 from Wallonia (conducted in 2009), this study presents empirical evidence of differences between both regions in attitudes towards and practice of euthanasia. Acceptance of euthanasia by the general population was found to be slightly higher in Flanders than in Wallonia. Compared with their Flemish counterparts, Walloon physicians held more negative attitudes towards performing euthanasia and towards the reporting obligation, less often labelled hypothetical cases correctly as euthanasia, and less often defined a case of euthanasia having to be reported. A higher proportion of Flemish physicians had received a euthanasia request since the introduction of the law. In cases of a euthanasia request, Walloon physicians consulted less often with an independent physician. Requests were more often granted in Flanders than in Wallonia (51% vs 38%), and performed euthanasia cases were more often reported (73% vs 58%). The study points out some significant differences between Flanders and Wallonia in practice, knowledge and attitudes regarding euthanasia and its legal requirements which are likely to explain the discrepancy between Wallonia and Flanders in the number of euthanasia cases reported. Cultural factors seem to play an important role in the

Neonatal mice (that is, pups younger than 6 d) must be exposed to CO2 for as long as 50 min to achieve euthanasia. Alternatively, other inhalant anesthetic agents have been used to euthanize laboratory rodent species. We investigated the efficacy of isoflurane at saturated vapor pressure to euthanize neonatal mice. Neonatal mice (n = 76; age, 1 or 2 d) were exposed to isoflurane in a sealed, quart-size (0.95-L) plastic bag at room temperature. Righting and withdrawal reflexes were absent in less than 2 min. After 30 min of exposure to isoflurane, pups were removed and monitored for recovery. All pups were cyanotic and showed no detectable signs of life when they were removed from the bag. However, after 30 to 120 min after removal from the bag, 24% of isoflurane-overexposed pups began gasping and then resumed normal respiration and regained a normal pink coloration. These results demonstrate that isoflurane overexposure at saturated vapor pressure for 30 min is insufficient to euthanize neonatal mice and that isoflurane overexposure must be followed by a secondary means of euthanasia.

In many western societies health professionals play a powerful role in people's experiences of dying. Religious professionals, such as pastors, are also confronted with the issues surrounding death and dying in their work. It is therefore reasonable to assume that the ways in which death-related topics, such as euthanasia, are constructed in a given culture are affected by the views of these professionals. This qualitative study addresses the ways in which Finnish physicians and religious professionals perceive and describe euthanasia and conceptualises these descriptions and views as social representations. Almost all the physicians interviewed saw that euthanasia does not fit the role of a physician and anchored it to different kinds of risks such as the slippery slope. Most of the religious and world-view professionals also rejected euthanasia. In this group, euthanasia was rejected on the basis of a religious moral code that forbids killing. Only one of the religious professionals - the freethinker with an atheist world-view - accepted euthanasia and described it as a personal choice, as did the one physician interviewed who accepted it. The article shows how the social representations of euthanasia are used to protect professional identities and to justify their expert knowledge of death and dying.
There is unanimity among states to protect the continuation of life of the individual as a safeguard against their collective extinction. The right to life is accordingly guaranteed but its antithesis, the right to die is the subject of an unending debate. The controversy over the right to die is deepened by rapid advances in medicine, creating the capability for prolongation of life beyond the span which one's natural strength can endure. Ghana's supreme law explicitly guarantees the right to life but remains ambiguous on right to die, particularly euthanasia and assisted dying. Thus, some of the other rights, such as the right to dignity and not to be tortured, can creatively be exploited to justify some instances of euthanasia. Ghana's criminal code largely proscribes euthanasia. Notwithstanding, proscription of euthanasia and assisted dying by the law, in Ghana's empirical work undertaken in some of the communities in Ghana, suggests that euthanasia is quietly practisedin health facilities and private homes, especially in the rural areas. Contrary to the popular reasons assigned in the literature of the Western world, with respect to the practice or quest for legalization of euthanasia as being a necessity for providing relief from pain or hopeless quality of life, empirical data from social and anthropological studies conducted in Ghana reveal that poverty is the motivation for informal euthanasia practice in Ghana rather than genuine desire on part of patients to die or their relatives to see to their accelerated death. Apart from poverty, traditional cultural values of African societies consider non-natural death as a taboo and ignominy to the victim and his family. Thus, any move by the government to legalize euthanasia will need to be informed by widely held consultations and a possible referendum; otherwise the law may be just a mere transplant of Western models of legislation on euthanasia without reflecting the ethos of the African people.

Voluntary Refusal of Food and Fluid (VRFF) is one possibility for patients in palliative situations to hasten death and avoid further suffering. By means of a mapping literature review this article describes the medical, nursing, ethical and legal perspective of care for people who wish to hasten death using VRFF. The results show that the wish to die is affected by psychological, social, spiritual and physical factors. VRFF is a little-known, legal and independently viable method to hasten death. Reducing fluid intake to 40 ml daily, the dying process takes one to three weeks. VRFF can be regarded as a natural death, foregoing treatment or as suicide. In contrast to physician assisted suicide or euthanasia, patients dying by VRFF experience a "natural" dying process and the decision is reversible in the first few days. As authority to act lies with the person wishing to die professionals and family caring for the dying are practicing palliative care, as opposed to assisted suicide or euthanasia. Professionals and family involved in the decision-making process are confronted with various ethical problems. Further research concerning VRFF and its implications for practice is necessary.

Experimental manipulations of body ownership have indicated that multisensory integration is central to forming bodily self-representation. Voluntary self-touch is a unique multisensory situation involving corresponding motor, tactile and proprioceptive signals. Yet, even though self-touch is frequent in everyday life, its contribution to the formation of body ownership is not well understood. Here we investigated the role of voluntary self-touch in body ownership using a novel adaptation of the rubber hand illusion (RHI), in which a robotic system and virtual reality allowed participants self-touch of real and virtual hands. In the first experiment, active and passive self-touch were applied in the absence of visual feedback. In the second experiment, we tested the role of visual feedback in this bodily illusion. Finally, in the third experiment, we compared active and passive self-touch to the classical RHI in which the touch is administered by the experimenter. We hypothesized that active self-touch would increase ownership over the virtual hand through the addition of motor signals strengthening the bodily illusion. The results indicated that active self-touch elicited stronger illusory ownership compared to passive self-touch and sensory only stimulation, and show an important role for active self-touch in the formation of bodily self.

In Memory of Ed Pellegrino. Euthanasia in Belgium is not limited to terminally ill patients. It may be applied to patients with chronic degenerative diseases. Currently, people in Belgium wish to make it possible to euthanize incompetent patients who suffer from dementia. This article explains the Belgian law and then explores arguments for and against euthanasia of patients with dementia. It probes the dementia paradox by elucidating Dworkin's distinction between critical and experiential interests, arguing that at the end-of-life this distinction is not clearcut. It argues against euthanasia for patients with dementia, for respecting patients' humanity and for providing them with more care, compassion, and good doctoring.

Aruna Ramachandra Shanbaug breathed her last after 42 years of being in a persistent vegetative state. Euthanasia in any form is not permitted in India and it was only in the year 2011 that a petition was filed in the court that urged the cessation of her force feeding with a nasogastric tube and the request for her peaceful death. What followed was a string of arguments and counter arguments relating to Euthanasia. The sad demise of Aruna Shanbaug is not the end of an individual, but may be the end of the road for clear cut guidelines and legislation on Euthanasia in India.

Some persons with refractory and unbearable suffering caused by an illness or medical condition wish to die by euthanasia or physician assisted suicide in order to have a certain and painless death. Physicians who agree to help a patient to die have previously confirmed that his/her illness cannot be cured, his/her suffering cannot be relieved and he/ she is of sound mind. Being well informed of his/her condition, the patient arrives to the conclusion that in his/her situation being death is better that being alive. How to explain that there are very few places in which physicians are allowed to help their patients to die? The main arguments against legalizing physician-assisted death are analyzed in this article.

Motor training consisting of repetitive thumb movements results in encoding of motor memories in the primary motor cortex. It is not known if proprioceptive input originating in the training movements is sufficient to produce this effect. In this study, we compared the ability of training consisting of voluntary (active) and passively-elicited (passive) movements to induce this form of plasticity. Active training led to successful encoding accompanied by characteristic changes in corticomotor excitability, while passive training did not. These results support a pivotal role for voluntary motor drive in coding motor memories in the primary motor cortex.

Organ donation after euthanasia has been performed more than 40 times in Belgium and the Netherlands together. Preliminary results of procedures that have been performed until now demonstrate that this leads to good medical results in the recipient of the organs. Several legal aspects could be changed to further facilitate the combination of organ donation and euthanasia. On the ethical side, several controversies remain, giving rise to an ongoing, but necessary and useful debate. Further experiences will clarify whether both procedures should be strictly separated and whether the dead donor rule should be strictly applied. Opinions still differ on whether the patient's physician should address the possibility of organ donation after euthanasia, which laws should be adapted and which preparatory acts should be performed. These and other procedural issues potentially conflict with the patient's request for organ donation or the circumstances in which euthanasia (without subsequent organ donation) traditionally occurs.

Background: In 2002, the Belgian Act on Euthanasia came into effect, regulating the intentional ending of life by a physician at the patient’s explicit request. We undertook this study to describe trends in officially reported euthanasia cases in Belgium with regard to patients’ sociodemographic and clinical profiles, as well as decision-making and performance characteristics. Methods: We used the database of all euthanasia cases reported to the Federal Control and Evaluation Committee on Euthanasia in Belgium between Jan. 1, 2003, and Dec. 31, 2013 (n = 8752). The committee collected these data with a standardized registration form. We analyzed trends in patient, decision-making and performance characteristics using a χ2 technique. We also compared and analyzed trends for cases reported in Dutch and in French. Results: The number of reported euthanasia cases increased every year, from 235 (0.2% of all deaths) in 2003 to 1807 (1.7% of all deaths) in 2013. The rate of euthanasia increased significantly among those aged 80 years or older, those who died in a nursing home, those with a disease other than cancer and those not expected to die in the near future (p < 0.001 for all increases). Reported cases in 2013 most often concerned those with cancer (68.7%) and those under 80 years (65.0%). Palliative care teams were increasingly often consulted about euthanasia requests, beyond the legal requirements to do so (p < 0.001). Among cases reported in Dutch, the proportion in which the person was expected to die in the foreseeable future decreased from 93.9% in 2003 to 84.1% in 2013, and palliative care teams were increasingly consulted about the euthanasia request (from 34.0% in 2003 to 42.6% in 2013). These trends were not significant for cases reported in French. Interpretation: Since legalization of euthanasia in Belgium, the number of reported cases has increased each year. Most of those receiving euthanasia were younger than 80 years and were dying of cancer

The aim of this study is to assess the knowledge, attitudes and experiences of Spanish nurses in relation to euthanasia and physician-assisted suicide. In an online questionnaire completed by 390 nurses from Andalusia, 59.1% adequately identified a euthanasia situation and 64.1% a situation involving physician-assisted suicide. Around 69% were aware that both practices were illegal in Spain, while 21.4% had received requests for euthanasia and a further 7.8% for assisted suicide. A total of 22.6% believed that cases of euthanasia had occurred in Spain and 11.4% believed the same for assisted suicide. There was greater support (70%) for legalisation of euthanasia than for assisted suicide (65%), combined with a greater predisposition towards carrying out euthanasia (54%), if it were to be legalised, than participating in assisted suicide (47.3%). Nurses in Andalusia should be offered more education about issues pertaining to the end of life, and extensive research into this area should be undertaken.
This presentation provides an overview of international voluntary renewable energy markets, with a focus on the United States and Europe. The voluntary renewable energy market is the market in which consumers and institutions purchase renewable energy to match their electricity needs on a voluntary basis. In 2010, the U.S. voluntary market was estimated at 35 terawatt-hours (TWh) compared to 300 TWh in the European market, though key differences exist. On a customer basis, Australia has historically had the largest number of customers, pricing for voluntary certificates remains low, at less than $1 megawatt-hour, though prices depend on technology.

In the United States, electricity consumers are told that they can "buy" electricity from renewable energy projects, versus fossil fuel-fired facilities, through participation in a voluntary green power program. The marketing messages communicate to consumers that their participation and premium payments for a green label will cause additional renewable energy generation and thereby allow them to claim they consume electricity that is absent pollution as well as reduce pollutant emissions. Renewable Energy Certificates (RECs) and wind energy are the basis for the majority of the voluntary green power market in the United States. This dissertation addresses the question: Do project developers respond to the voluntary REC market in the United States by altering their decisions to invest in wind turbines? This question is investigated by modeling and probabilistically quantifying the effect of the voluntary REC market on a representative wind power investor in the United States using data from formal expert elicitations of active participants in the industry. It is further explored by comparing the distribution of a sample of wind power projects supplying the voluntary green power market in the United States against an economic viability model that incorporates geographic factors. This dissertation contributes the first quantitative analysis of the effect of the voluntary REC market on project investment. It is found that 1) RECs should be not treated as equivalent to emission offset credits, 2) there is no clearly credible role for voluntary market RECs in emissions trading markets without dramatic restructuring of one or both markets and the environmental commodities they trade, and 3) the use of RECs in entity-level GHG emissions accounting (i.e., "carbon footprinting") leads to double counting of emissions and therefore is not justified. The impotence of the voluntary REC market was, at least in part, due to the small magnitude of the REC price signal and lack of

Recent evaluation of the practice of euthanasia and related medical decisions at the end of life in the Netherlands has shown a slight decrease in the frequency of physician-assisted death since the enactment of the Euthanasia Law in 2002. This paper focuses on the absence of euthanasia cases concerning patients with dementia and a written advance euthanasia directive, despite the fact that the only real innovation of the Euthanasia Law consisted precisely in allowing physicians to act upon such directives. The author discusses two principal reasons for this absence. One relates to the uncertainty about whether patients with advanced dementia truly experience the suffering they formerly feared. There is reason to assume that they don't, as a consequence of psychological adaptation and progressive unawareness (anosognosia). The second, more fundamental reason touches upon the ethical relevance of shared understanding and reciprocity. The author argues that, next to autonomy and mercifulness, "reciprocity" is a condition sine qua non for euthanasia. The absence thereof in advanced dementia renders euthanasia morally inconceivable, even if there are signs of suffering and notwithstanding the presence of an advance euthanasia directive. This does not mean, however, that advance euthanasia directives of patients with dementia are worthless. They might very well have a role in the earlier stages of certain subtypes of the disease. To illustrate this point the author presents a case in which the advance directive helped to create a window of opportunity for reciprocity and shared decision-making.

This article reports on the relationship of personality and euthanasia attitudes. Results from a survey of 165 Iranian students showed that religiosity, honesty-humility, agreeableness, and extraversion were related to negative attitudes toward euthanasia, whereas openness was related to acceptance of euthanasia, with the unconventionality facet driving this relationship. Moreover, openness explained additional variance when added to a multivariate model containing religiosity and HEXACO factors. This study illustrates the possibility of accounting for variation beyond the traditional group level predictors of attitudes toward euthanasia and promoting future cross-cultural studies into personality and end-of-life issues and informing end-of-life conversations at the bedside.

Euthanasia is legal in Belgium if due care criteria are met, which is judged by committees including physicians, ethicists, and jurists. We examined whether students in these disciplines differ in how they judge euthanasia as an acceptable act. A cross-sectional, anonymous e-mail survey revealed that they have similar attitudes and accept its legalization. Therefore, joint decision-making of physicians, ethicists, and lawyers regarding euthanasia seems to have a common attitudinal base in Belgium. However, they differ to some extent regarding the conditions they put forward for euthanasia being acceptable. Philosophy of life (religion) was an independent predictor of these attitudes.

Background Recent events in Canada have mobilized public debate concerning the controversial issue of euthanasia. Physicians represent an essential stakeholder group with respect to the ethics and practice of euthanasia. Further, their opinions can hold sway with the public, and their public views about this issue may further reflect back upon the medical profession itself. Methods We conducted a discourse analysis of print media on physicians’ perspectives about end-of-life care. Print media, in English and French, that appeared in Canadian newspapers from 2008 to 2012 were retrieved through a systematic database search. We analyzed the content of 285 articles either authored by a physician or directly referencing a physician’s perspective. Results We identified 3 predominant discourses about physicians’ public views toward euthanasia: 1) contentions about integrating euthanasia within the basic mission of medicine, 2) assertions about whether euthanasia can be distinguished from other end-of-life medical practices and 3) palliative care advocacy. Interpretation Our data showed that although some medical professional bodies appear to be supportive in the media of a movement toward the legalization of euthanasia, individual physicians are represented as mostly opposed. Professional physician organizations and the few physicians who have engaged with the media are de facto representing physicians in public contemporary debates on medical aid in dying, in general, and euthanasia, in particular. It is vital for physicians to be aware of this public debate, how they are being portrayed within it and its potential effects on impending changes to provincial and national policies. PMID:26389090

The use of voluntary programs targeting resource conservation on private land has become increasingly prevalent in environmental policy. Voluntary programs potentially offer significant benefits over regulatory and market-based approaches. This article examines the factors affecting landowner participation in voluntary forest conservation programs using a combination of parcel-level GIS and remotely sensed data and semi-structured interviews of landowners in Monroe County, Indiana. A logistic regression model is applied to determine the probability of participation based on landowner education, membership in other non-forest voluntary programs, dominant land use activity, parcel size, distance from urban center, land resource portfolios, and forest cover. Both land use activity and the spatial configuration of a landholder’s resource portfolio are found to be statistically significant with important implications for the design and implementation of voluntary programs.

Suicide is one of the greatest concerns in psychiatric practice, with considerable efforts devoted to prevention. The psychiatric view of suicide tends to equate it with depression or other forms of mental illness. However, some forms of suicide occur independently of mental illness and within a framework of cultural sanctioning such that they aren’t regarded as suicide at all. Despite persistent taboos against suicide, euthanasia and physician-assisted suicide in the context of terminal illness is increasingly accepted as a way to preserve autonomy and dignity in the West. Seppuku, the ancient samurai ritual of suicide by self-stabbing, was long considered an honorable act of self-resolve such that despite the removal of cultural sanctioning, the rate of suicide in Japan remains high with suicide masquerading as seppuku still carried out both there and abroad. Suicide as an act of murder and terrorism is a practice currently popular with Islamic militants who regard it as martyrdom in the context of war. The absence of mental illness and the presence of cultural sanctioning do not mean that suicide should not be prevented. Culturally sanctioned suicide must be understood in terms of the specific motivations that underlie the choice of death over life. Efforts to prevent culturally sanctioned suicide must focus on alternatives to achieve similar ends and must ultimately be implemented within cultures to remove the sanctioning of self-destructive acts.

Directive 2010/63/EU on the protection of animals used for scientific purposes requires that the killing of mammal foetuses during the last third of their gestational period should be accomplished through effective and humane methods. The fact that murine foetuses are resistant to hypoxia-mediated euthanasia renders the current euthanasia methods ineffective or humane for the foetuses when these methods are applied to pregnant female mice. We have assessed the time to death of foetuses after performing either indirect (dam euthanasia) or direct (via intraplacental injection--a new approach to euthanasia) euthanasia methods in order to determine a euthanasia method that is appropriate, ethical and efficient for the killing of mouse foetuses. The respective times to death of foetuses after performing the three most commonly used euthanasia methods (namely cervical dislocation, CO2inhalation and intraperitoneal sodium pentobarbital administration) were recorded. Absence of foetal heartbeat was monitored via ultrasound. We consider that the most effective and humane method of foetal euthanasia was the one able to achieve foetal death within the shortest possible period of time. Among the indirect euthanasia methods assessed, the administration of a sodium pentobarbital overdose to pregnant female mice was found to be the fastest for foetuses, with an average post-treatment foetal death of approximately 29.8 min. As for the direct euthanasia method assessed, foetal time to death after intraplacental injection of sodium pentobarbital was approximately 14 min. Significant differences among the different mouse strains employed were found. Based on the results obtained in our study, we consider that the administration of a sodium pentobarbital overdose by intraplacental injection to be an effective euthanasia method for murine foetuses.
The US Department of Energy, Carlsbad Area Office (DOE-CAO) has completed a voluntary release assessment sampling program at selected Solid Waste Management Units (SWMUs) at the Waste Isolation Pilot Plant (WIPP). This Voluntary Release Assessment/Corrective Action (RA/CA) report has been prepared for final submittal to the Environmental protection Agency (EPA) Region 6, Hazardous Waste Management Division and the New Mexico Environment Department (NMED) Hazardous and Radioactive Materials Bureau to describe the results of voluntary release assessment sampling and proposed corrective actions at the SWMU sites. The Voluntary RA/CA Program is intended to be the first phase in implementing the Resource Conservation and Recovery Act (RCRA) Facility Investigation (RFI) and corrective action process at the WIPP. Data generated as part of this sampling program are intended to update the RCRA Facility Assessment (RFA) for the WIPP (Assessment of Solid Waste Management Units at the Waste Isolation Pilot Plant), NMED/DOE/AIP 94/1. This Final Voluntary RA/CA Report documents the results of release assessment sampling at 11 SWMUs identified in the RFA. With this submittal, DOE formally requests a No Further Action determination for these SWMUs. Additionally, this report provides information to support DOE`s request for No Further Action at the Brinderson and Construction landfill SWMUs, and to support DOE`s request for approval of proposed corrective actions at three other SWMUs (the Badger Unit Drill Pad, the Cotton Baby Drill Pad, and the DOE-1 Drill Pad). This information is provided to document the results of the Voluntary RA/CA activities submitted to the EPA and NMED in August 1995.

Exercise has been shown to increase hippocampal neurogenesis, but the effects of exercise on oligodendrocyte generation have not yet been reported. In this study, we evaluated the hypothesis that voluntary exercise may affect neurogenesis, and more in particular, oligodendrogenesis, in the thoracic segment of the intact spinal cord of adult nestin-GFP transgenic mice. Voluntary exercise for 7 and 14 days increased nestin-GFP expression around the ependymal area. In addition, voluntary exercise for 7 days significantly increased nestin-GFP expression in both the white and gray matter of the thoracic segment of the intact spinal cord, whereas, 14 days-exercise decreased nestin-GFP expression. Markers for immature oligodendrocytes (Transferrin and CNPase) were significantly increased after 7 days of voluntary exercise. These results suggest that voluntary exercise positively influences oligodendrogenesis in the intact spinal cord, emphasizing the beneficial effect of voluntary exercise as a possible co-treatment for spinal cord injury.

To many in India and elsewhere, the life and thoughts of Mohandas Karamchand Gandhi are a source of inspiration. The idea of non-violence was pivotal in his thinking. In this context, Gandhi reflected upon the possibility of what is now called 'euthanasia' and 'assisted suicide'. So far, his views on these practices have not been properly studied. In his reflections on euthanasia and assisted suicide, Gandhi shows himself to be a contextually flexible thinker. In spite of being a staunch defender of non-violence, Gandhi was aware that violence may sometimes be unavoidable. Under certain conditions, killing a living being could even be an expression of non-violence. He argued that in a few rare cases it may be better to kill people who are suffering unbearably at the end of life. In this way, he seems to support euthanasia and assisted suicide. Yet, Gandhi also thought that as long as care can be extended to a dying patient, his or her suffering could be relieved. Since in most cases relief was thus possible, euthanasia and assisted suicide were in fact redundant. By stressing the importance of care and nursing as an alternative to euthanasia and assisted suicide, Gandhi unconsciously made himself an early advocate of palliative care in India. This observation could be used to strengthen and promote the further development of palliative care in India.
Objective—Consultation of another physician is an important method of review of the practice of euthanasia. For the project "support and consultation in euthanasia in Amsterdam" which is aimed at professionalising consultation, a protocol for consultation was developed to support the general practitioners who were going to work as consultants and to ensure uniformity. Participants—Ten experts (including general practitioners who were experienced in euthanasia and consultation, a psychiatrist, a social geriatrician, a professor in health law and a public prosecutor) and the general practitioners who were going to use the protocol. Evidence—There is limited literature on consultation: discursive articles and empirical studies describing the practice of euthanasia. Consensus—An initial draft on the basis of the literature was commented on by the experts and general practitioners in two rounds. Finally, the protocol was amended after it had been used during the training of consultants. Conclusions—The protocol differentiates between steps that are necessary in a consultation and steps that are recommended. Guidelines about four important aspects of consultation were given: independence, expertise, tasks and judgment of the consultant. In 97% of 109 consultations in which the protocol was used the consultant considered the protocol to be useful to a greater or lesser extent. Although this protocol was developed locally, it also employs universal principles. Therefore it can be of use in the development of consultation elsewhere. Key Words: Euthanasia • assisted suicide • consultation • quality assurance • protocol PMID:11579191

A pivotal due care criterion for lawful euthanasia in the Netherlands is that doctors must be convinced that a patient requesting for euthanasia, suffers unbearably. Our study aims to find out how doctors judge if a patient suffers unbearably. How do doctors bridge the gap from 3rd person assessment to 1st person experience? We performed a qualitative interview study among 15 physicians, mainly general practitioners, who participated earlier in a related quantitative survey on the way doctors apply the suffering criterion. Results show that doctors follow different 'cognitive routes' when assessing a patients suffering in the context of a euthanasia request. Sometimes doctors do this imagining how she herself would experience the situation of the patient ('imagine self'). Doctors may also try to adopt the perspective of the patient and imagine what the situation is like for this particular patient ('imagine other'). Besides this we found that the (outcome of the) assessment is influenced by a doctor's private norms, values and emotions considering (the performance of) euthanasia. We conclude by arguing why doctors should be aware of both the 'cognitive route' followed as well as the influence of their own personal norms on the assessment of suffering in the context of euthanasia requests.
Voluntary cough maneuvers are characterized by transient peak expiratory flows (PEF) exceeding the maximum expiratory flow-volume (MEFV) curve. In some cases, these flows can be well in excess of the MEFV, generally referred to as supramaximal flows. Understanding the flow-structure interaction involved in these maneuvers is the main goal of this work. We present a simple theoretical model for investigating the dynamics of voluntary cough and forced expiratory maneuvers. The core modeling idea is based on a 1-D model of high Reynolds number flow through flexible-walled tubes. The model incorporates key ingredients involved in these maneuvers: the expiratory effort generated by the abdominal and expiratory muscles, the glottis and the flexibility and compliance of the lung airways. Variations in these allow investigation of the expiratory flows generated by a variety of single cough maneuvers. The model successfully reproduces PEF which is shown to depend on the cough generation protocol, the glottis reopening time and the compliance of the airways. The particular highlight is in simulating supramaximal PEF for very compliant tubes. The flow-structure interaction mechanisms behind these are discussed. The wave speed theory of flow limitation is used to characterize the PEF. Existing hypotheses of the origin of PEF, from cough and forced expiration experiments, are also tested using this model.

Companion animal welfare in our society has become increasingly important, yet many healthy animals are euthanized in veterinary facilities. How is it possible to explain the simultaneous presence of these opposing views of obligation toward animals? The goal of this study was to describe convenience euthanasia of companion animals as experienced by veterinarians in order to understand their thought processes. A qualitative study was undertaken to analyze the results of interviews of 14 veterinarians. The study showed that veterinarians interviewed assessed convenience euthanasia based mainly on their subjective evaluation of the owner-animal bond. As most owner-animal bonds stem from an anthropocentric point of view, decisions on convenience euthanasia were taken mostly by considering the veterinarian's and the client/owner's interests.

In vitro fertilization (IVF) is used to produce mouse embryos for a variety of reasons. We evaluated the effect of the method of euthanasia on the fertilization rate in 2 different IVF protocols. Oocytes collected from C57BL/6J female mice euthanized by CO2 inhalation or cervical dislocation were used in IVF with fresh sperm from either wild-type or genetically engineered C57BL/6J. Compared with CO2 inhalation, cervical dislocation improved the resulting rate of fertilization by 18% in an IVF method using Cook media and by 13% in an IVF method using methyl-B cyclodextrin and reduced glutathione. The lower fertilization rate due to euthanasia by CO2 inhalation was accompanied by changes in blood pH and body temperature despite efforts to minimize temperature drops. In our hands, euthanasia by cervical dislocation improved fertilization rates and consequently reduced the number of egg-donor mice required.

The number of people suffering from dementia will rise considerably in the years to come. This will have important implications for society. People suffering from dementia have to rely on relatives and professional caregivers when their disorder progresses. Some people want to determine for themselves their moment of death, if they should become demented. They think that the decline in personality caused by severe dementia is shocking and unacceptable. In this context, some people consider euthanasia as a way to avoid total deterioration. In this article, we discuss some practical and ethical dilemmas regarding euthanasia in persons with severe dementia based on an advance euthanasia directive. We are using a personalist approach in dealing with these ethical dilemmas.
In Memory of Ed Pellegrino Euthanasia in Belgium is not limited to terminally ill patients. It may be applied to patients with chronic degenerative diseases. Currently, people in Belgium wish to make it possible to euthanize incompetent patients who suffer from dementia. This article explains the Belgian law and then explores arguments for and against euthanasia of patients with dementia. It probes the dementia paradox by elucidating Dworkin’s distinction between critical and experiential interests, arguing that at the end-of-life this distinction is not clearcut. It argues against euthanasia for patients with dementia, for respecting patients’ humanity and for providing them with more care, compassion, and good doctoring. PMID:26661050

The humane euthanasia of animals for population management, or culling, has been suggested as one possible tool for managing animal populations for sustainability, and recent, highly publicized euthanasia of zoo animals in Copenhagen has stimulated global conversation about population management in zoos. We conducted a nationwide survey of U.S. zoo and aquarium personnel, including keepers, managers, and leaders of AZA animal programs, to assess their overall attitudes regarding population management euthanasia. The surveyed populations were generally very aware of the concept of population management euthanasia. Managers and animal program leaders were more supportive of euthanasia than keepers. We found that regardless of role, men were more supportive of euthanasia than women. Those personnel who were aware of instances of population management euthanasia at their institutions before were more supportive of it than those who were not. Support for culling varied with the kind of animal being considered for it, with three general taxon acceptability groupings emerging. Education, tenure in the profession, taxonomic expertise, and whether or not the responder took the survey before or after the Copenhagen events were not strong predictors of attitudes. Overall, the surveyed populations were approximately evenly split in terms of being in favor of euthanasia, not supporting euthanasia, or being unsure. Most responders indicated that they would be more likely to accept culling if more information was provided on its rationale. These results will form the basis for further discussions on the role of humane euthanasia for population management. Zoo Biol. 35:187-200, 2016. © 2016 Wiley Periodicals, Inc.

A survey about opinions on end-of-life issues of a population represented by 1,171 people in the waiting room of general practitioners' surgeries was conducted in a province of northern Italy. Most subjects did not consider suicide as a reasonable option even in cases of a serious and incurable disease. Moreover, subjects did not consider euthanasia as a possible option either; however, they did express an opposite attitude when considering euthanasia in a third-person perspective. People with a personal history of suicidal behavior appear to present as a different population, overall expressing more open attitudes.

Relapse of previously extinguished fear presents a significant, pervasive obstacle to the successful long-term treatment of anxiety and trauma-related disorders. Thus, identification of a novel means to enhance fear extinction to stand the passage of time and generalize across contexts is of the utmost importance. Acute bouts of exercise can be used as inexpensive, noninvasive treatment strategies to reduce anxiety, and have been shown to enhance memory for extinction when performed in close temporal proximity to the extinction session. However, it is unclear whether acute exercise can be used to prevent relapse of fear, and the neural mechanisms underlying this potential effect are unknown. The current study therefore examined whether acute exercise during extinction of auditory fear can protect against the later relapse of fear. Male F344 rats lacking an extended history of wheel running were conditioned to fear a tone CS and subsequently extinguished within either a freely mobile running wheel, a locked wheel, or a control context lacking a wheel. Rats exposed to fear extinction within a freely mobile wheel ran during fear extinction, and demonstrated reduced fear as well as attenuated corticosterone levels during re-exposure to the extinguished CS during the relapse test in a novel context 1week later. Examination of cfos mRNA patterns elicited by re-exposure to the extinguished CS during the relapse test revealed that acute exercise during extinction decreased activation of brain circuits classically involved in driving fear expression and interestingly, increased activity within neurons of the direct striatal pathway involved in reward signaling. These data suggest that exercise during extinction reduces relapse through a mechanism involving the direct pathway of the striatum. It is suggested that a positive affective state could become associated with the CS during exercise during extinction, thus resulting in a relapse-resistant extinction memory.

The current study therefore examined whether acute exercise during extinction of auditory fear can protect against the later relapse of fear. Male, F344 rats lacking an extended history of wheel running were conditioned to fear a tone CS and subsequently extinguished within either a freely mobile running wheel, a locked wheel, or a control context lacking a wheel. Rats exposed to fear extinction within a freely mobile wheel ran during fear extinction, and demonstrated reduced fear as well as attenuated corticosterone levels during re-exposure to the extinguished CS during the relapse test in a novel context 1 week later. Examination of cfos mRNA patterns elicited by re-exposure to the extinguished CS during the relapse test revealed that acute exercise during extinction decreased activation of brain circuits classically involved in driving fear expression and interestingly, increased activity within neurons of the direct striatal pathway involved in reward signaling. These data suggest that exercise during extinction reduces relapse through a mechanism involving the direct pathway of the striatum. It is suggested that a positive affective state could become associated with the CS during exercise during extinction, thus resulting in a relapse-resistant extinction memory. PMID

Anticipatory control of upright posture is the focus of this study that combines experimental and modeling work. Individuals were asked to raise or lower their arms from two initial postures such that the final posture of the arm was at 90 degrees with respect to the body. Holding different weights in the hand varied the magnitude of perturbation to postural stability generated by the arm movement. Whole body kinematics and ground reaction forces were measured. Inverse dynamic analysis was used to determine the internal joint moments at the shoulder, hip, knee and ankle, and reaction forces at the shoulder. Center of mass (COM) of the arm, posture (rest of the body without the arms) and whole body (net COM) were also determined. Changes in joint moment at the hip, knee and ankle revealed a significant effect of the direction of movement. The polarities of the joint moment response were appropriate for joint stabilization. Net COM change showed a systematic effect of the direction of movement even though the arm COM was displaced by the same amount and in the same direction for both arm raising and lowering conditions. In order to determine the effects of the passive forces and moments on the posture COM, the body was modeled as an inverted pendulum. The model was customized for each participant; the relevant model parameters were estimated from data obtained from each trial. The ankle joint stiffness and viscosity were adjusted to ensure postural equilibrium prior to arm movement. Joint reactive forces and moments generated by the arm movements were applied at the shoulder level of this inverted pendulum; these were the only inputs and no active control was included. The posture COM profile from the model simulation was calculated. Results show that simulated posture COM profile and measured posture COM profile are identical for about 200 ms following the onset of arm movement and then they deviate. Therefore, the initial control of COM is passive in nature and the

The mesolimbic dopaminergic pathway has been implicated in many rewarding behaviors, including the consumption of ethanol and voluntary exercise. It has become apparent that different rewarding stimuli activate this pathway, and therefore it is possible for these behaviors to influence each other, i.e. hedonic substitution. Using adult female C57BL/6J mice, we demonstrate that voluntary access to a running wheel substantially reduces the consumption and preference of ethanol. Furthermore, we examined gene expression of several genes involved in regulating the mesolimbic dopaminergic pathway, which we hypothesized to be the main pathway involved in hedonic substitution. In the striatum, we observed a reduction in mRNA expression of Drd1a due to exercise. Hippocampal Bdnf mRNA increased in response to exercise and decreased in response to ethanol. Furthermore, there was an interaction effect of exercise and ethanol on the expression of Slc18a2 in the midbrain. These data suggest an important role for this pathway, and especially for Bdnf and Slc18a2 in regulating hedonic substitution.

This article is a complement to "A Template for Non-Religious-Based Discussions Against Euthanasia" by Melissa Harintho, Nathaniel Bloodworth, and E. Wesley Ely which appeared in the February 2015 Linacre Quarterly. Herein we build upon Daniel Sulmasy's opening and closing arguments from the 2014 Intelligence Squared debate on legalizing assisted suicide, supplemented by other non-faith-based arguments and thoughts, providing four nontheistic arguments against physician-assisted suicide and euthanasia: (1) "it offends me"; (2) slippery slope; (3) "pain can be alleviated"; (4) physician integrity and patient trust. Lay Summary: Presented here are four non-religious, reasonable arguments against physician-assisted suicide and euthanasia: (1) "it offends me," suicide devalues human life; (2) slippery slope, the limits on euthanasia gradually erode; (3) "pain can be alleviated," palliative care and modern therapeutics more and more adequately manage pain; (4) physician integrity and patient trust, participating in suicide violates the integrity of the physician and undermines the trust patients place in physicians to heal and not to harm.
A study illustrates how legal sanction promotes a culture that transforms suicide into assisted suicide and encourages choosing death when faced with serious illness. The question of extending legal euthanasia to those not physically ill complicates the issue. Also, doctors may feel they can end a terminally-ill patient's life without consent.…

Respect for autonomy is typically considered a key reason for allowing physician assisted suicide and euthanasia. However, several recent papers have claimed this to be grounded in a misconception of the normative relevance of autonomy. It has been argued that autonomy is properly conceived of as a value, and that this makes assisted suicide as well as euthanasia wrong, since they destroy the autonomy of the patient. This paper evaluates this line of reasoning by investigating the conception of valuable autonomy. Starting off from the current debate in end-of-life care, two different interpretations of how autonomy is valuable is discussed. According to one interpretation, autonomy is a personal prudential value, which may provide a reason why euthanasia and assisted suicide might be against a patient's best interests. According to a second interpretation, inspired by Kantian ethics, being autonomous is unconditionally valuable, which may imply a duty to preserve autonomy. We argue that both lines of reasoning have limitations when it comes to situations relevant for end-of life care. It is concluded that neither way of reasoning can be used to show that assisted suicide or euthanasia always is impermissible.

The euthanasia of invertebrates used in scientific investigations poses unanswered questions regarding the rapid induction of unconsciousness with minimal distress and pain. Relative to vertebrates, invertebrates’ sensory experience of pain, nociception, and physiologic response to aversive stimuli are poorly characterized. The scientific communities in the European Union, Canada, United States, Australia, and New Zealand join in consensus regarding the need to address alleviation of pain and distress in cephalopods (octopus, squid, and so forth), which have the best-characterized nervous system among invertebrates. In the current study, we evaluated various euthanasia techniques in a terrestrial gastropod species, with priority on animal wellbeing, scientific variability, feasibility in both field and laboratory settings, and acceptability by personnel. In addition, we demonstrated that the 2-step method of euthanasia described in the AVMA Guidelines as acceptable for aquatic invertebrates is effective for terrestrial snails and meets all welfare and scientific requirements. This 2-step method first induces anesthesia by immersion in 5% ethanol (laboratory-grade ethanol or beer) followed by immersion in a euthanizing and tissue-preserving solution of 70% to 95% ethanol or 10% neutral buffered formalin. Furthermore, alternative methods of euthanasia for terrestrial snails commonly used in field research, such as live immersion in concentrated ethanol or formalin, were shown to be unacceptable.

This study compared the extent of twitch and M-wave potentiation (POT) between voluntary and stimulated quadriceps contractions performed at the same intensity. Sixteen healthy men completed 10-s isometric knee extensions at 40% of the maximal voluntary contraction torque under electrical stimulation and voluntary conditions. Single stimuli were delivered to the femoral nerve to evoke twitches before (PRE) and from 3 to 600 s after the end of each conditioning contraction. Changes in twitch contractile properties and M-wave characteristics were compared between the conditions. The extent of twitch peak torque POT was smaller for the stimulated (122+/-20% of PRE) than for the voluntary condition (133+/-20% of PRE). The magnitude of POT for the maximal rate of twitch torque development was also smaller for the stimulated trial. Rectus femoris M-wave amplitude was potentiated by the voluntary but not by the stimulated contraction. It was concluded that stimulated contractions resulted in smaller twitch and M-wave POT than voluntary contractions, despite equivalent torque output and duration. The spatially and temporally fixed recruitment of motor units with electrical stimulation and therefore the lower number of activated motor units compared with voluntary actions of equal intensity could explain the present findings.

Hastening the death of another whether through assisted suicide or euthanasia is the subject of intense debate in the UK and elsewhere. In this paper we use a nationally representative survey of public attitudes - the British Social Attitudes survey - to examine changes in attitudes to the legalisation of physician provided euthanasia (PPE) over almost 30 years (1983-2012) and the role of religious beliefs and religiosity in attitudes over time. Compatible questions about attitudes to euthanasia were available in the six years of 1983, 1984, 1989, 1994, 2005, and 2012. We study the trends in the support for legalisation through these time points and the relationship between attitudes, religious denomination and religiosity, controlling for a series of covariates. In total, 8099 individuals provided answers to the question about PPE in the six years of the study. The support for legalisation rose from around 76.95% in 1983 to 83.86% in 2012. This coincided with an increase in secularisation exhibited in the survey: the percentage of people with no religious affiliation increasing from 31% to 45.4% and those who do not attend a religious institution (e.g. church) increasing from 55.7% to 65.03%. The multivariate analysis demonstrates that religious affiliation and religiosity as measured by religious institution attendance frequency are the main contributors to attitudes towards euthanasia, and that the main increase in support happened among the group with least religious affiliation. Other socio-demographic characteristics do not seem to alter these attitudes systematically across the years. Our study demonstrates an increase in the support of euthanasia legalisation in Britain in the last 30 years coincided with increased secularisation. It does not follow, however, that trends in public support are immutable nor that a change in the law would improve on the current pragmatic approach toward hastening death by a physician adopted in England and Wales in terms of

Poststroke hemiparesis limits the ability to reach, in part due to involuntary muscle co-activation (synergies). Robotic approaches are being developed for both therapeutic benefit and continuous assistance during activities of daily living. Robotic assistance may enable participants to exert less effort, thereby reducing expression of the abnormal co-activation patterns, which could allow participants to reach further. This study evaluated how well participants could perform a reaching task with robotic assistance that was either provided independent of effort in the vertical direction or in the sagittal plane in proportion to voluntary effort estimated from electromyograms (EMG) on the affected side. Participants who could not reach targets without assistance were enabled to reach further with assistance. Constant anti-gravity force assistance that was independent of voluntary effort did not reduce the quality of reach and enabled participants to exert less effort while maintaining different target locations. Force assistance that was proportional to voluntary effort on the affected side enabled participants to exert less effort and could be controlled to successfully reach targets, but participants had increased difficulty maintaining a stable position. These results suggest that residual effort on the affected side can produce an effective command signal for poststroke assistive devices.

Electromyostimulation (EMS) and voluntary muscle contraction (VC) constitute different modes of muscle activation and induce different acute physiological effects on the neuromuscular system. Long-term application of each mode of muscle activation can produce different muscle adaptations. It seems theoretically possible to completely or partially cumulate the muscle adaptations induced by each mode of muscle activation applied separately. This work consisted of examining the literature concerning the muscle adaptations induced by long-term application of the combined technique (CT) [i.e. EMS is combined with VC - non-simultaneously] compared with VC and/or EMS alone in healthy subjects and/or athletes and in post-operative knee-injured subjects. In general, CT induced greater muscular adaptations than VC whether in sports training or rehabilitation. This efficiency would be due to the fact that CT can facilitate cumulative effects of training completely or partially induced by VC and EMS practiced alone. CT also provides a greater improvement of the performance of complex dynamic movements than VC. However, EMS cannot improve coordination between different agonistic and antagonistic muscles and thus does not facilitate learning the specific coordination of complex movements. Hence, EMS should be combined with specific sport training to generate neuromuscular adaptations, but also allow the adjustment of motor control during a voluntary movement. Likewise, in a therapeutic context, CT was particularly efficient to accelerate recovery of muscle contractility during a rehabilitation programme. Strength loss and atrophy inherent in a traumatism and/or a surgical operation would be more efficiently compensated with CT than with VC. Furthermore, CT also restored more functional abilities than VC. Finally, in a rehabilitation context, EMS is complementary to voluntary exercise because in the early phase of rehabilitation it elicits a strength increase, which is necessary

“Sense of agency” refers to the experience that links one’s voluntary actions to their external outcomes. It remains unclear whether this ubiquitous experience is hardwired, arising from specific signals within the brain’s motor systems, or rather depends on associative learning, through repeated cooccurrence of voluntary movements and their outcomes. To distinguish these two models, we asked participants to trigger a tone by a voluntary keypress action. The voluntary action was always associated with an involuntary movement of the other hand. We then tested whether the combination of the involuntary movement and tone alone might now suffice to produce a sense of agency, even when the voluntary action was omitted. Sense of agency was measured using an implicit marker based on time perception, namely a shift in the perceived time of the outcome toward the action that caused it. Across two experiments, repeatedly pairing an involuntary movement with a voluntary action induced key temporal features of agency, with the outcome now perceived as shifted toward the involuntary movement. This shift required involuntary movements to have been previously associated with voluntary actions. We show that some key aspects of agency may be transferred from voluntary actions to involuntary movements. An internal volitional signal is required for the primary acquisition of agency but, with repeated association, the involuntary movement in itself comes to produce some key temporal features of agency over the subsequent outcome. This finding may explain how humans can develop an enduring sense of agency in nonnatural cases, like brain–machine interfaces. PMID:27436902

A Self-Paced Team Sport Match Simulation Results In Reductions In Voluntary Activation And Modifications To Biological, Perceptual And Performance Measures At Half-Time, And For Up To 96 Hours Post-Match.
Tofari, Paul; Kemp, Justin; Cormack, Stuart
Assessing responses to soccer match-play is limited by match variability or unrealistic simulations. To address this, the biological, perceptual, and performance response were assessed using a self-paced, simulated soccer match protocol using a non-motorized treadmill. Twelve male team-sport athletes performed the 90-min simulation. Match activity; quadriceps twitch interpolation [voluntary activation (%VA) and potentiated twitch (POT)]; biochemical markers; strength and power performance; rating of perceived exertion (RPE) and self-report wellness were collected pre-, half-time, post-, and 2, 24, 48, 72 and 96-h post-match. Change compared to pre-match was calculated using effect size (ES) ±90% confidence limit, and relationships were assessed using regression analysis. Subjects covered 12445.8±768.7 m at 87.1±3.2% maximal HR (mean±SD). Reductions in %VA and POT was present at half-time (-0.38±0.46 and -0.79±0.30, respectively), and persisted post-match. Squat jump height decreased at half-time (-0.42±0.31) and was decreased until Post96. Perceptual fatigue, soreness (-0.92±0.88 and -1.49±0.76, respectively) and creatine kinase (CK, 1.11±0.43) peaked at Post24. Pre-test strength (N.kg) correlated with changes in CK (r=-0.58 to -0.81), peak oxygen consumption (V˙ O2peak) correlated with reduced perceived wellness at Post24 (r=0.44 to 0.58) and RPE post (r=-0.71±0.28). High-speed running correlated with soreness (r=0.42) and very high speed running with reduced POT (r=0.61). Previously unreported half-time reductions in %VA and POT plateaued by post-match, suggesting a role in regulating second-half performance. Perceptual and neuromuscular responses appear related to running intensity. Greater lower-body strength and V˙ O2peak were associated with less CK (i.e., muscle damage) and perceptual responses post-match, respectively, suggesting a training focus should be placed on these capacities.

The majority of research and therapeutic actions in Parkinson's disease (PD) focus on the encephalic areas, however, the potential involvement of the spinal cord in its genesis has received little attention. Here we examined spinal locomotor circuitry activation in patients with PD using various types of central and peripheral tonic stimulation and compared results to those of age-matched controls. Subjects lay on their sides with both legs suspended, allowing low-friction horizontal rotation of the limb joints. Air-stepping can be used as a unique and important model for investigating human rhythmogenesis since its manifestation is largely facilitated by the absence of external resistance. In contrast to the frequent occurrence of non-voluntary stepping responses in healthy subjects, both peripheral (muscle vibration) and central (Jendrassik maneuver, mental task, Kohnstamm phenomenon) tonic influences had little if any effect on rhythmic leg responses in PD. On the other hand, a remarkable feature of voluntary air-stepping movements in patients was a significantly higher frequency of leg oscillations than in age-matched controls. A lack of non-voluntary stepping responses was also observed after dopaminergic treatment despite the presence of prominent shortening reactions (SRs) to passive movements. We argue that the state and the rhythmogenesis capacity of the spinal circuitry are impaired in patients with PD. In particular, the results suggest impaired central pattern generator (CPG) access by sensory and central activations.

One of the main concept objectives of smart cities is to create a quality living environment that is long-term sustainable and economically justified. In that context, modern cities are aware of the exposure to various forms of physical and non-physical pollution that needs to be remediated, eliminated or reduced. To achieve that it is necessary to quality determine the sources and reasons of each pollution. The most prominent examples of physical pollution that affects the quality of life of citizens in cities are light and noise pollution. Noise pollution or noise, is mostly the consequence of road and rail traffic in cities and it directly affects the health of citizens. Traffic control, reduction of peak congestion, dispersion and traffic redirection or building protective barriers, are ways that cities use to reduce the amount of noise or its effects. To make these measures efficient it is necessary to obtain the information related to the level of noise in certain areas, streets, cities. To achieve this, smart cities use noise mapping. The city of Zagreb since 2012, participates in the i-SCOPE project (interoperable Smart City services trough Open Platform for urban Ecosystems). i-SCOPE delivers an open platform on top of which it develops, three "smart city" services: optimization of energy consumption through a service for accurate assessment of solar energy potential and energy loss at building level, environmental monitoring through a real-time environmental noise mapping service leveraging citizen's involvement will who act as distributed sensors city-wide measuring noise levels through an application on their mobile phones and improved inclusion and personal mobility of aging and diversely able citizens through an accurate personal routing service. The students of Faculty of Geodesy University of Zagreb, who enrolled in the course Thematic Cartography, were actively involved in the voluntary data acquisition in order to monitor the noise in real time

Abstract Background: Reports about regulations and laws on Euthanasia and Physician Assisted Suicide (PAS) are becoming increasingly common in the media. Many groups have expressed opposition to euthanasia and PAS while those in favor argue that severely chronically ill and debilitated patients have a right to control the timing and manner of their death. Others argue that both PAS and euthanasia are ethically legitimate in rare and exceptional cases. Given that these discussions as well as the new and proposed laws and regulations may have a powerful impact on patients, caregivers, and health care providers, the International Association for Hospice and Palliative Care (IAHPC) has prepared this statement. Purpose: To describe the position of the IAHPC regarding Euthanasia and PAS. Method: The IAHPC formed a working group (WG) of seven board members and two staff officers who volunteered to participate in this process. An online search was performed using the terms “position statement”, “euthanasia” “assisted suicide” “PAS” to identify existing position statements from health professional organizations. Only statements from national or pan-national associations were included. Statements from seven general medical and nursing associations and statements from seven palliative care organizations were identified. A working document including a summary of the different position statements was prepared and based on these, an initial draft was prepared. Online discussions among the members of the WG took place for a period of three months. The differences were reconciled by email discussions. The resulting draft was shared with the full board. Additional comments and suggestions were incorporated. This document represents the final version approved by the IAHPC Board of Directors. Result: IAHPC believes that no country or state should consider the legalization of euthanasia or PAS until it ensures universal access to palliative care services and to

Objectives To identify patterns in euthanasia requests and practices relating to psychiatric patients; to generate recommendations for future research. Design Retrospective analysis of data obtained through medical file review. Setting Outpatient psychiatric clinical setting in the Dutch-speaking region of Belgium, between October 2007 and December 2011; follow-up at the end of December 2012. Participants 100 consecutive psychiatric patients requesting euthanasia based on psychological suffering associated with psychiatric disorders (77 women, 23 men; mean age 47 years; age range 21–80 years). Main outcome measures Patient sociodemographic characteristics; diagnoses; decisions on euthanasia requests; circumstances of euthanasia procedures; patient outcomes at follow-up. Results Most patients had been referred for psychiatric counselling by their physician (n=55) or by LEIF (Life End Information Forum) (n=36). 90 patients had >1 disorder; the most frequent diagnoses were depression (n=58) and personality disorder (n=50). 38 patients required further testing and/or treatment, including 13 specifically tested for autism spectrum disorder (ASD); 12 received an ASD diagnosis (all Asperger syndrome). In total, 48 of the euthanasia requests were accepted and 35 were carried out. Of the 13 remaining patients whose requests were accepted, 8 postponed or cancelled the procedure, because simply having this option gave them enough peace of mind to continue living. In December 2012, 43 patients had died, including 35 by euthanasia; others died by suicide (6), palliative sedation (1) and anorexia nervosa (1). Conclusions Depression and personality disorders are the most common diagnoses in psychiatric patients requesting euthanasia, with Asperger syndrome representing a neglected disease burden. Further research is needed, especially prospective quantitative and qualitative studies, to obtain a better understanding of patients with psychiatric disorders who request
In June 1991, the National Forum for Voluntary Motherhood and the Decriminalization of Abortion was convened in Tuxtla Gutierrez, Chiapas, Mexico. The forum culminated in the signing of a pact in which participants pledged to support the women of Chiapas in their efforts to win approval of legislation assuring the right to legal abortion. The action in Chiapas was viewed as the beginning of a national legislative process aimed at achieving juridical recognition of the sexual freedom of women. The participants planned to promote discussion in each community and state of existing abortion legislation and the proposed reforms to assure women the right to abortion. Space will be demanded in the mass media in order to inform the population. The movement will seek to develop a widespread local and national consensus on the right to voluntary maternity. Voluntary maternity implies recognition of the rights to women to make decisions regarding their own sexuality and fertility. It implies availability of sex education and contraception, as well as access to safe and legal abortions. Voluntary maternity implies elimination by society of morbidity and mortality due to causes associated with reproduction, and it implies generalized use of contraception and elimination of involuntary sterilization. Voluntary maternity requires that the state develop an ethic of protection of mothers and children, and that authoritarian demographic programs that do not recognize the humanity and autonomy of women be abandoned. Voluntary maternity requires protection by public institutions, and it requires that women and children have access to a decent standard of living. It requires as well that the daily care of children cease to be the exclusive responsibility of women and that it be shared by men. Women cannot be free as long as maternity is compulsory. It is proposed that the discussions and proposals made to local legislatures will eventually be brought before the national Congress in

The purpose of the Decontamination, Decommissioning, and Reutilization (DDR) Division of the American Nuclear Society (ANS) is to advance the technology of decontamination, decommissioning, and reutilization of nuclear and former nuclear installations, materials, facilities, and sites . This includes sharing collective decommissioning experiences and lessons learned with others in the industry. An integral part of the work of the DDR Division is the preparation of voluntary decommissioning standards through its recently re-established DDR Standards Committee. This Committee intends to support development of various standards with other divisions of the ANS. The Committee also intends to participate with external organizations to disseminate information and lessons learned regarding decontamination activities, and participate in the development of voluntary decommissioning standards. External organizations, such as ASTM International, are involved in the development of consensus standards for nuclear decommissioning work. This paper describes the work of the DDR Standards Committee on a new co-operative initiative with ASTM International to develop voluntary consensus standards for nuclear decommissioning work.

The aim of this study was to investigate whether (1) spinal modulation would change after non-exhausting eccentric exercise of the plantar flexor muscles that produced muscle soreness and (2) central modulation of the motor command would be linked to the development of muscle soreness. Ten healthy subjects volunteered to perform a single bout of backward downhill walking exercise (duration 30 min, velocity 1 ms−1, negative grade −25%, load 12% of body weight). Neuromuscular test sessions [H-reflex, M-wave, maximal voluntary torque (MVT)] were performed before, immediately after, as well as 1–3 days after the exercise bout. Immediately after exercise there was a −15% decrease in MVT of the plantar flexors partly attributable to an alteration in contractile properties (−23% in electrically evoked mechanical twitch). However, MVT failed to recover before the third day whereas the contractile properties had significantly recovered within the first day. This delayed recovery of MVT was likely related to a decrement in voluntary muscle drive. The decrease in voluntary activation occurred in the absence of any variation in spinal modulation estimated from the H-reflex. Our findings suggest the development of a supraspinal modulation perhaps linked to the presence of muscle soreness. PMID:17978834

Clinicians frequently worry that medications used to treat pain and suffering at the end of life might also hasten death. Intentionally hastening death, or euthanasia, is neither legal nor ethically appropriate in children. In this article, we explore some of the historical and legal background regarding appropriate end-of-life care and outline what distinguishes it from euthanasia. Good principles include clarity of goals and assessments, titration of medications to effect, and open communication. When used appropriately, medications to treat symptoms should rarely hasten death significantly. Medications and interventions that are not justifiable are also discussed, as are the implications of palliative sedation and withholding fluids or nutrition. It is imperative that clinicians know how to justify and use such medications to adequately treat suffering at the end of life within a relevant clinical and legal framework.
This article presents a comparative analysis of euthanasia and physician-assisted suicide policy in The Netherlands and the state of Oregon in the United States. The topics of euthanasia and physician-assisted suicide are discussed in the context of the historical setting of The Netherlands and the United States with special emphasis placed on public opinion, role of the courts and the legislative bodies, and opinions of physicians. Major similarities and differences in the laws of The Netherlands and Oregon are discussed. The article examines whether the passage of the law has led to a slide down the slippery slope in The Netherlands and Oregon as had been suggested by the opponents of the law. The article concludes that the empirical evidence does not support the contention of the opponents. However, the author argues that the potential for this happening is much greater in The Netherlands than in Oregon.

Voluntary covert attention selects relevant sensory information for prioritized processing. The behavioral and neural consequences of such selection have been extensively documented, but its phenomenology has received little empirical investigation. Involuntary attention increases perceived spatial frequency (Gobell & Carrasco, 2005), but involuntary attention can differ from voluntary attention in its effects on performance in tasks mediated by spatial resolution (Yeshurun, Montagna, & Carrasco, 2008). Therefore, we ask whether voluntary attention affects the subjective appearance of spatial frequency--a fundamental dimension of visual perception underlying spatial resolution. We used a demanding rapid serial visual presentation task to direct voluntary attention and measured perceived spatial frequency at the attended and unattended locations. Attention increased the perceived spatial frequency of suprathreshold stimuli and also improved performance on a concurrent orientation discrimination task. In the control experiment, we ruled out response bias as an alternative account by using a lengthened interstimulus interval, which allows observers to disengage attention from the cued location. In contrast to the main experiment, the observers showed neither increased perceived spatial frequency nor improved orientation discrimination at the attended location. Thus, this study establishes that voluntary attention increases perceived spatial frequency. This phenomenological consequence links behavioral and neurophysiological studies on the effects of attention.
Background An important principle underlying the Dutch Euthanasia Act is physicians' responsibility to alleviate patients' suffering. The Dutch Act states that euthanasia and physician-assisted suicide are not punishable if the attending physician acts in accordance with criteria of due care. These criteria concern the patient's request, the patient's suffering (unbearable and hopeless), the information provided to the patient, the presence of reasonable alternatives, consultation of another physician and the applied method of ending life. To demonstrate their compliance, the Act requires physicians to report euthanasia to a review committee. We studied which arguments Dutch physicians use to substantiate their adherence to the criteria and which aspects attract review committees' attention. Methods We examined 158 files of reported euthanasia and physician-assisted suicide cases that were approved by the review committees. We studied the physicians' reports and the verdicts of the review committees by using a checklist. Results Physicians reported that the patient's request had been well-considered because the patient was clear-headed (65%) and/or had repeated the request several times (23%). Unbearable suffering was often substantiated with physical symptoms (62%), function loss (33%), dependency (28%) or deterioration (15%). In 35%, physicians reported that there had been alternatives to relieve patients' suffering which were refused by the majority. The nature of the relationship with the consultant was sometimes unclear: the consultant was reported to have been an unknown colleague (39%), a known colleague (21%), otherwise (25%), or not clearly specified in the report (24%). Review committees relatively often scrutinized the consultation (41%) and the patient's (unbearable) suffering (32%); they had few questions about possible alternatives (1%). Conclusion Dutch physicians substantiate their adherence to the criteria in a variable way with an emphasis on

This report documents the status and trends of 'compliance'--renewable energy certificate (REC) markets used to meet state renewable portfolio standard (RPS) requirements--and 'voluntary' markets--those in which consumers and institutions purchase renewable energy to match their electricity needs on a voluntary basis. Today, 29 states and the District of Columbia have an RPS, more than half of all U.S. electricity customers have an option to purchase some type of green power product directly from a retail electricity provider, and all consumers have the option to purchase RECs. This report documents REC activities and trends in the United States. The compliance REC market analysis includes analysis of REC trading, regional REC markets, REC tracking systems, types of compliance RECs, compliance REC pricing trends, and an overview of compliance with RPS polices. The voluntary REC analysis presents data and analysis on voluntary market sales and customer participation, products and premiums, green pricing marketing and administrative expenses, voluntary REC pricing, and the voluntary carbon offsets market. The report concludes with a discussion of upcoming guidance from the Federal Trade Commission on green marketing claims, the emergence of community solar programs, and the potential impact of Dodd-Frank regulations on the REC market.

A distinction is commonly drawn between continuous sedation until death and physician-assisted suicide/euthanasia. Only the latter is found to involve killing, whereas the former eludes such characterization. I argue that continuous sedation until death is equivalent to physician-assisted suicide/euthanasia in that both involve killing. This is established by first defining and clarifying palliative sedation therapies in general and continuous sedation until death in particular. A case study analysis and a look at current practices are provided. This is followed by a defense of arguments in favor of definitions of death centering on higher brain (neocortical) functioning rather than on whole brain or cardiopulmonary functioning. It is then shown that continuous sedation until death simulates higher brain definitions of death by eliminating consciousness. Appeals to reversibility and double effect fail to establish any distinguishing characteristics between the simulation of death that occurs in continuous sedation until death and the death that occurs as a result of physician-assisted suicide/euthanasia. Concluding remarks clarify the moral ramifications of these findings.

'Unbearable suffering' is a pivotal criterion for lawful euthanasia in the Netherlands. The due-care criterion is not defined in the law and could refer to conditions varying from physical pain to psychological forms of suffering. It is unknown, however, what doctors consider 'unbearable suffering' and for what kind of suffering they are willing to grant a euthanasia request. We conducted a vignette-study among Dutch general practitioners (n=115, response 38%). We found high concordance between the classification of a patient's suffering as 'unbearable' and the willingness to grant a euthanasia request. Most doctors are only inclined to classify a patient's suffering as 'unbearable' when suffering is directly related to untreatable and actual pain or physical symptoms. Doctors' judgment of suffering varied strongly in cases in which physical symptoms are absent and a patient suffers from a combination of irreversible functional loss and 'existential' kinds of suffering. Although some doctors (17%) stick to the idea that physical symptoms are a necessary condition for 'unbearable suffering', a majority is willing to occasionally make an exception. When and for which case an individual doctor will make such an exception, is highly unpredictable. Various explanations for the findings are discussed.

Consultation with another physician is considered to be an important safeguard of the practice of euthanasia and physician-assisted suicide. The objective is to describe the frequency and characteristics of consultation in cases of euthanasia or physician-assisted suicide (EAS) in the Netherlands. Data from two cross-sectional descriptive nationwide surveys, carried out in 1995, were used. Questionnaires were mailed to physicians attending 6060 deaths, identified from death certificates, and a stratified sample of 405 physicians were interviewed. In 1990, a cross-sectional descriptive postal survey of a random sample of 1042 general practitioners took place. Consultation took place in 63% of cases of EAS in the Netherlands, in 99% of the cases reported to the public prosecutor and in approximately 37% of unreported cases. In almost half of the unreported cases the decision had been discussed less formally with at least one colleague. In 1990, 7% of general practitioners met all 8 criteria for good consultation; this increased to 64% in 1995. Of the respondents, 26% had at some time advised against performing euthanasia or assisted suicide when acting as a consultant. This study shows that approximately two thirds of all cases of EAS are safeguarded by consultation. Although in the majority of these cases the consultation is of good quality, there is certainly still room for improvement. The quality of consultation could be improved, for instance, by appointing independent and specifically trained consultants.

Fertilized chicken eggs are suggested as an alternative to mammalian models. The chorioallantoic membrane (CAM) of the chick embryo is widely used for examination of angiogenesis, xenotransplants and for virus production. Unfortunately, it is mostly not taken into account, that the chick embryo's ability to experience pain starts to develop at day 7 of breeding. In our view, this model is only in accordance with the 3 R principles, if an appropriate anesthesia of the chick embryo in potentially painful procedures is provided. Although many experimental approaches are performed on the none-innervated CAM, the euthanasia of the embryo strongly requires a more human technique than the usually used freezing at -20°C, decapitation or in ovo fixation with paraformaldehyde without prior anesthesia. However, protocols regarding feasible and ethical methods for anesthesia and euthanasia of avian embryos are currently not available. Therefore, we established an easy and reliable method for the euthanasia and short-term anesthesia of the chick embryo.

The Voluntary Reporting Program for greenhouse gases is part of an attempt by the U.S. Government to develop innovative, low-cost, and nonregulatory approaches to limit emissions of greenhouse gases. It is one element in an array of such programs introduced in recent years as part of the effort being made by the United States to comply with its national commitment to stabilize emissions of greenhouse gases under the Framework Convention on Climate Change. The Voluntary Reporting Program, developed pursuant to Section 1605(b) of the Energy Policy Act of 1992, permits corporations, government agencies, households, and voluntary organizations to report to the Energy Information Administration (EIA) on actions taken that have reduced or avoided emissions of greenhouse gases.

Objectives To estimate the rate of reporting of euthanasia cases to the Federal Control and Evaluation Committee and to compare the characteristics of reported and unreported cases of euthanasia. Design Cross sectional analysis. Setting Flanders, Belgium. Participants A stratified at random sample was drawn of people who died between 1 June 2007 and 30 November 2007. The certifying physician of each death was sent a questionnaire on end of life decision making in the death concerned. Main outcome measures The rate of euthanasia cases reported to the Federal Control and Evaluation Committee; physicians’ reasons for not reporting cases of euthanasia; the relation between reporting and non-reporting and the characteristics of the physician and patient; the time by which life was shortened according to the physician; the labelling of the end of life decision by the physician involved; and differences in characteristics of due care between reported and unreported euthanasia cases. Results The survey response rate was 58.4% (3623/6202 eligible cases). The estimated total number of cases of euthanasia in Flanders in 2007 was 1040 (95% CI 970 to 1109), thus the incidence of euthanasia was estimated as 1.9% of all deaths (95% CI 1.6% to 2.3%). Approximately half (549/1040 (52.8%, 95% CI 43.9% to 60.5%)) of all estimated cases of euthanasia were reported to the Federal Control and Evaluation Committee. Physicians who perceived their case as euthanasia reported it in 93.1% (67/72) of cases. Cases of euthanasia were reported less often when the time by which life was shortened was less than one week compared with when the perceived life shortening was greater (37.3% v 74.1%; P<0.001). Unreported cases were generally dealt with less carefully than reported cases: a written request for euthanasia was more often absent (87.7% v 17.6% verbal request only; P<0.001), other physicians and caregivers specialised in palliative care were consulted less often (54.6% v 97.5%; 33.0% v 63

In debates about euthanasia and assisted suicide, it is rare to find an article that begins with an expression of neutral interest and then proceeds to examine the various arguments and data before drawing conclusions based upon the results of a scholarly investigation. Although authors frequently give the impression of being impartial in their introduction, they invariably reach their prior conclusions. Positions tend to be clearly dichotomized: either one believes that the practice of euthanasia or assisted suicide is totally acceptable or completely unacceptable in a just and moral society. Where there is some admission of a gray zone of incertitude, authors attempt to persuade us that their beliefs (preferences) are the only sensible way to resolve outstanding dilemmas. The practice of vehemently promoting a "pro" or "con" position may be useful when societies must decide to either legalize certain practices or not. Although only a handful of countries have thus far accepted the legal practice of euthanasia or assisted suicide (Belgium, Luxembourg, The Netherlands, the U.S. states of Montana, Oregon, Vermont and Washington, and Switzerland), scholarly articles in recent trends mainly promote legalization, to the point of recommending expansion of the current practices. Is this a case of the philosophers being ahead of their time in promoting and rationalizing the wave of the future? Alternatively, does the small number of countries that have legalized these practices indicate a substantial gap between the beliefs and desires of common citizens and the universe of the 'abstracted realm'? For the time being, what we do know is that more countries and states are debating legalization of euthanasia or assisted suicide, the nature of laws and legal practices vary greatly and both ethical and empirical assessments of current practices are the subject of much controversy. This article presents an examination of the premises and evidence in the rhetoric of assisted
Euthanasia has received increasing attention in both academic and public debates as one of the most controversial issues. However, the contribution of psychology-related themes to the topic has had little role on these ongoing debates. The aim of the present study is twofold: (1) to explore the main themes relating to euthanasia as provided by psychology-related research; (2) to analyze the temporal trends of psychology-related research on euthanasia over the last decades. A comprehensive search of academic literature was conducted on PsychINFO database. A qualitative software-based thematic analysis was carried out on 602 journal abstracts published from 1935 to 2014. This study highlighted four different thematic areas which characterized the scientific discourse on euthanasia: (1) moral values, in terms of religious, philosophical, and social implications concerning the individual's decision to die; (2) professional ethics, in terms of health and social workers' legal responsibility in death assistance; (3) end-of-life care, with regard to medical options provided to support individuals nearing death; and (4) patient's right to healthcare, in terms of access to palliative care and better quality of dying. Euthanasia discourse over the last decades seems to be overall characterized by two main dimensions: (1) the increasing trend of social legitimacy and acceptability of euthanasia over time, which moved from ethical to healthcare issues; and (2) the curvilinear temporal trend about the request/provision process in euthanasia, which moved from patient's decision for ending life (mainly characterizing the most past and recent research) to the role of health professionals (with a peak in the 1990s). The results suggest palliative care as a potential future research area which can provide healthcare providers with skills to 'connect' with patients, understand patients' hidden agendas, and grant a good quality of life and dying process.

In a rotating environment, goal-oriented voluntary movements are initially disrupted in trajectory and endpoint, due to movement-contingent Coriolis forces, but accuracy is regained with additional movements. We studied whether adaptation acquired in a voluntary, goal-oriented postural swaying task performed during constant-velocity counterclockwise rotation (10 RPM) carries over to recovery from falling induced using a hold and release (H&R) paradigm. In H&R, standing subjects actively resist a force applied to their chest, which when suddenly released results in a forward fall and activation of an automatic postural correction. We tested H&R postural recovery in subjects (n = 11) before and after they made voluntary fore-aft swaying movements during 20 trials of 25 s each, in a counterclockwise rotating room. Their voluntary sway about their ankles generated Coriolis forces that initially induced clockwise deviations of the intended body sway paths, but fore-aft sway was gradually restored over successive per-rotation trials, and a counterclockwise aftereffect occurred during postrotation attempts to sway fore-aft. In H&R trials, we examined the initial 10- to 150-ms periods of movement after release from the hold force, when voluntary corrections of movement path are not possible. Prerotation subjects fell directly forward, whereas postrotation their forward motion was deviated significantly counterclockwise. The postrotation deviations were in a direction consistent with an aftereffect reflecting persistence of a compensation acquired per-rotation for voluntary swaying movements. These findings show that control and adaptation mechanisms adjusting voluntary postural sway to the demands of a new force environment also influence the automatic recovery of posture. PMID:24304863

Some important vaccinations are not included in the routine childhood immunization schedule in Japan. Voluntary vaccinations are usually paid as an out-of-pocket expense. Low voluntary vaccination coverage rates and high target disease incidence are assumed to be a consequence of voluntary vaccination. Therefore, this study aimed to explore factors associated with voluntary vaccination patterns in children. We conducted an online survey of 1243 mothers from a registered survey panel who had at least one child 2 months to <3 years of age. The voluntary vaccination mainly correlated positively with annual household income and mothers' positive opinions about voluntary vaccinations, but negatively with number of children. Financial support, especially for low income households and households with more than one child, may motivate parents to vaccinate their children. Communication is also an important issue. More opportunities for education and information about voluntary vaccinations should be provided to mothers without distinguishing between voluntary and routine vaccination.

Gavage is a widely performed technique for daily dosing in laboratory rodents. Although effective, gavage comprises a sequence of potentially stressful procedures for laboratory animals that may introduce bias into experimental results, especially when the drugs to be tested interfere with stress-dependent parameters. We aimed to test vehicles suitable for drug delivery by voluntary ingestion in rats. Specifically, Male Wistar rats (age, 2 to 3 mo) were used to test nut paste (NUT), peanut butter (PB), and sugar paste (SUG) as vehicles for long-term voluntary oral administration of losartan, an angiotensin II receptor blocker. Vehicles were administered for 28 d without drug to assess effects on the glucose level and serum lipid profile. Losartan was mixed with vehicles and either offered to the rats or administered by gavage (14 d) for subsequent quantification of losartan plasma levels by HPLC. After a 2-d acclimation period, all rats voluntarily ate the vehicles, either alone or mixed with losartan. NUT administration reduced blood glucose levels. The SUG group had higher concentrations of losartan than did the gavage group, without changes in lipid and glucose profiles. Our results showed that NUT, PB, and SUG all are viable for daily single-dose voluntary ingestion of losartan and that SUG was the best alternative overall. Drug bioavailability was not reduced after voluntary ingestion, suggesting that this method is highly effective for chronic oral administration of losartan to laboratory rodents. PMID:26424254

Although Alzheimer's disease (AD) primarily manifests as cognitive deficits, the implicit sensorimotor processes that underlie social interactions, such as automatic imitation, seem to be preserved in mild and moderate stages of the disease, as is the ability to communicate with other persons. Nevertheless, when AD patients face more challenging tasks, which do not rely on automatic processes but on explicit voluntary mechanisms and require the patient to pay attention to external events, the cognitive deficits resulting from the disease might negatively affect patients' behavior. The aim of the present study was to investigate whether voluntary motor imitation, i.e., a volitional mechanism that involves observing another person's action and translating this perception into one's own action, was affected in patients with AD. Further, we tested whether this ability was modulated by the nature of the observed stimulus by comparing the ability to reproduce the kinematic features of a human demonstrator with that of a computerized-stimulus. AD patients showed an intact ability to reproduce the velocity of the observed movements, particularly when the stimulus was a human agent. This result suggests that high-level cognitive processes involved in voluntary imitation might be preserved in mild and moderate stages of AD and that voluntary imitation abilities might benefit from the implicit interpersonal communication established between the patient and the human demonstrator.

Zebrafish are an important laboratory animal model for biomedical research and are increasingly being used for behavioral neuroscience. Tricaine methanesulfonate (MS222) is the standard agent used for euthanasia of zebrafish. However, recent studies of zebrafish behavior suggest that MS222 may be aversive, and clove oil might be a possible alternative. In this study, we compared the effects of MS222 or clove oil as a euthanasia agent in zebrafish on the volume of blood collected and on serum levels of cortisol. Greater amounts of serum could be collected and lower serum levels of cortisol were present in fish euthanized with clove oil compared with equipotent dose of MS222. Euthanasia with clove oil did not blunt the expected elevation of serum cortisol levels elicited by an acute premortem stress. According to our findings, clove oil is a fast-acting agent that minimizes the cortisol response to euthanasia in zebrafish and allows the collection of large volumes of blood postmortem. These results represent a significant refinement in euthanasia methods for zebrafish.

Because many anesthetics work through depressing cell excitability, unanesthetized euthanasia has become common for research involving excitable tissues (for example muscle and nerve) to avoid these depressive effects. However, anesthetic use during euthanasia may be indicated for studies involving isolated tissues if the potential depressive effects of brief anesthetic exposure dissipate after subsequent tissue isolation, washout, and saline perfusion. We explore this here by measuring whether, when applied prior to euthanasia, standard immersion doses of 2 fish anesthetics, tricaine methanesulfonate (TMS; 100 mg/L, n = 6) and methyl 1-(1-phenylethyl)-1H-imidazole-5-carboxylate (metomidate, 10 mg/L, n = 6), have residual effects on the contractile properties (force and work output) of isolated and saline-perfused ventricular compact myocardium from rainbow trout (Oncorhynchus mykiss). Results suggest that direct exposure of muscle to immersion doses of TMS—but not metomidate—impairs muscle contractile performance. However, brief exposure (2 to 3 min) to either anesthetic during euthanasia only—providing that the agent is washed out prior to tissue experimentation—does not have an effect on the contractile properties of the myocardium. Therefore, the use of TMS, metomidate, and perhaps other anesthetics that depress cell excitability during euthanasia may be indicated when conducting research on isolated and rinsed tissues.

This fall, an extensive study will start to evaluate the Dutch Euthanasia Act. This law was enacted in 2002. According to this law, physicians must report cases of euthanasia and physician-assisted suicide. The cases are then judged by regional euthanasia review committees consisting of a lawyer, a physician and an ethicist. Only if they conclude that the case does not meet the requirements for prudent practice, it will be sent to the public prosecutor. The study will be focused on the practice of medical end-of-life decision-making, the functioning and effects of the Euthanasia Act, and opinions of physicians about the scope of the law and the demarcation between different end-of-life decisions. The study will comprise 4 sub-studies: a judicial evaluation, a death certificate study, a survey among physicians and a panel study among physicians, nurses, members of euthanasia review committees, lawyers and ethicists. This study is the fourth in a row of nationwide studies into end-of-life practices that have been performed since 1990. The previous studies contributed to the public debate about medical care at the end of life and to the development of policy in this field. It is expected that this study, by providing up-to-date information on and insight into end-of-life care in the Netherlands, will do the same.

Mechanical properties of skeletal muscles are often studied for controlled, electrically induced, maximal, or supra-maximal contractions. However, many mechanical properties, such as the force-length relationship and force enhancement following active muscle stretching, are quite different for maximal and sub-maximal, or electrically induced and voluntary contractions. Force depression, the loss of force observed following active muscle shortening, has been observed and is well documented for electrically induced and maximal voluntary contractions. Since sub-maximal voluntary contractions are arguably the most important for everyday movement analysis and for biomechanical models of skeletal muscle function, it is important to study force depression properties under these conditions. Therefore, the purpose of this study was to examine force depression following sub-maximal, voluntary contractions. Sets of isometric reference and isometric-shortening-isometric test contractions at 30% of maximal voluntary effort were performed with the adductor pollicis muscle. All reference and test contractions were executed by controlling force or activation using a feedback system. Test contractions included adductor pollicis shortening over 10 degrees, 20 degrees, and 30 degrees of thumb adduction. Force depression was assessed by comparing the steady-state isometric forces (activation control) or average electromyograms (EMGs) (force control) following active muscle shortening with those obtained in the corresponding isometric reference contractions. Force was decreased by 20% and average EMG was increased by 18% in the shortening test contractions compared to the isometric reference contractions. Furthermore, force depression was increased with increasing shortening amplitudes, and the relative magnitudes of force depression were similar to those found in electrically stimulated and maximal contractions. We conclude from these results that force depression occurs in sub

Individual levels of physical activity, and especially of voluntary physical exercise, highly contribute to the susceptibility for developing metabolic, cardiovascular diseases, and potentially to psychiatric disorders. Here, we applied a cross-species approach to explore a candidate genetic region for voluntary exercise levels. First, a panel of mouse chromosome substitution strains was used to map a genomic region on mouse chromosome 2 that contributes to voluntary wheel running levels - a behavioral readout considered a model of voluntary exercise in humans. Subsequently, we tested the syntenic region (HSA20: 51,212,545-55,212,986) in a human sample (Saint Thomas Twin Register; n=3038) and found a significant association between voluntary exercise levels (categorized into excessive and non-excessive exercise) and an intergenic SNP rs459465 (adjusted P-value of 0.001). Taking under consideration the methodological challenges embedded in this translational approach in the research of complex phenotypes, we wanted to further test the validity of this finding. Therefore, we repeated the analysis in an independent human population (ALSPAC data set; n=2557). We found a significant association of excessive exercise with two SNPs in the same genomic region (rs6022999, adjusted P-value of P=0.011 and rs6092090, adjusted P-value of 0.012). We explored the locus for possible candidate genes by means of literature search and bioinformatics analysis of gene function and of trans-regulatory elements. We propose three potential human candidate genes for voluntary physical exercise levels (MC3R, CYP24A1, and GRM8). To conclude, the identified genetic variance in the human locus 20q13.2 may affect voluntary exercise levels.

The purpose of this article is to explore the attitudes of lay people and physicians regarding euthanasia and physician-assisted suicide in terminally ill cancer patients in Greece. The sample consisted of 141 physicians and 173 lay people. A survey questionnaire was used concerning issues such as euthanasia, physician-assisted suicide, and so forth. Many physicians (42.6%) and lay people (25.4%, P = .002) reported that in the case of a cardiac and/or respiratory arrest, there would not be an effort to revive a terminally ill cancer patient. Only 8.1% of lay people and 2.1% of physicians agreed on physician-assisted suicide (P = .023). Many of the respondents, especially physicians, supported sedation but not euthanasia or physician-assisted suicide. However, many of the respondents would prefer the legalization of a terminally ill patient's hastened death.

The so called "Groningen Protocol" was conceived as a framework to discuss the euthanasia in neonates. Originally, it presents three groups of babies who might be candidates to this option. We analyzed the protocol in its original context and that of the Dutch society in which it was created. The analysis started with a careful reading of the protocol in both English and Dutch versions, translated later into Spanish. The medical and nursing staff participated in discussing it. A final consensus was reached. The Institutional Ethics Committee at our hospital discussed it freely and made recommendations for its application as a guideline to honestly discuss with parents the clinical condition of their babies, without permitting the option included literally in the word euthanasia. We selected four extremely ill infants. Their parents were interviewed at least twice daily: three stages were identified: the initial one of promoting all possible treatments; a second one of guarded and cautious request for the staff to evaluate "suffering", and a last one where requests were made to reduce therapeutic efforts to provide dignified death. A week after the death of their infants, they were presented with the facts of the protocol and the limits of our legal system. In all four cases the parents suggested that they would have chosen ending the life of their infants, in order to avoid them undue suffering. They clearly pointed out that this option emerged as a viable one to them once the ultimate outcome was evident. The protocol must not be viewed as a guideline for euthanasia in newborns, but rather as a mean to discuss the critical condition of an infant with the parents. Its direct implementation in our setting remains difficult. As a clear limitation for its overall application remains the definition of what is considered "unbearable suffering" in newborns, and how to certify when the infant has "no prospect". We emphasize the benefits of securing the help of the Ethics

The purpose of this study was to determine if inspiratory muscle training (IMT) alters the oxygen cost of breathing (Vo(2RM)) during voluntary hyperpnea. Sixteen male cyclists completed 6 wk of IMT using an inspiratory load of 50% (IMT) or 15% placebo (CON) of maximal inspiratory pressure (Pi(max)). Prior to training, a maximal incremental cycle ergometer test was performed to determine Vo(2) and ventilation (V(E)) at multiple workloads. Pre- and post-training, subjects performed three separate 4-min bouts of voluntary eucapnic hyperpnea (mimic), matching V(E) that occurred at 50, 75, and 100% of Vo(2 max). Pi(max) was significantly increased (P < 0.05) by 22.5 ± 8.7% from pre- to post-IMT and remained unchanged in the CON group. The Vo(2RM) required during the mimic trial corresponded to 5.1 ± 2.5, 5.7 ± 1.4, and 11.7% ± 2.5% of the total Vo(2) (Vo(2T)) at ventilatory workloads equivalent to 50, 75, and 100% of Vo(2 max), respectively. Following IMT, the Vo(2RM) requirement significantly decreased (P < 0.05) by 1.5% (4.2 ± 1.4% of Vo(2T)) at 75% Vo(2 max) and 3.4% (8.1 ± 3.5% of Vo(2T)) at 100% Vo(2 max). No significant changes were shown in the CON group. IMT significantly reduced the O(2) cost of voluntary hyperpnea, which suggests that a reduction in the O(2) requirement of the respiratory muscles following a period of IMT may facilitate increased O(2) availability to the active muscles during exercise. These data suggest that IMT may reduce the O(2) cost of ventilation during exercise, providing an insight into mechanism(s) underpinning the reported improvements in whole body endurance performance; however, this awaits further investigation.

Little is currently known about the context, nature, or frequency of nurses' responses to patient requests for help in dying. Only two empirical studies have surveyed American nurses about their actual responses to such requests. In one of those studies, 441 New England oncology nurses described how often patients ask them for help in ending their lives and also indicated how often they participated in assisted suicide and patient-requested euthanasia. One hundred and ten of those 441 nurses wrote comments on their returned questionnaires. This article describes the content analysis of those comments. Those oncology nurses who wrote have much to say about caring for patients at the end of life.

Under the assumption that the decision of vaccination is a voluntary behavior, in this paper, we use two forms of risk functions to characterize how susceptible individuals estimate the perceived risk of infection. One is uniform case, where each susceptible individual estimates the perceived risk of infection only based on the density of infection at each time step, so the risk function is only a function of the density of infection; another is preferential case, where each susceptible individual estimates the perceived risk of infection not only based on the density of infection but only related to its own activities/immediate neighbors (in network terminology, the activity or the number of immediate neighbors is the degree of node), so the risk function is a function of the density of infection and the degree of individuals. By investigating two different ways of estimating the risk of infection for susceptible individuals on complex network, we find that, for the preferential case, the spread of epidemic can be effectively controlled; yet, for the uniform case, voluntary vaccination mechanism is almost invalid in controlling the spread of epidemic on networks. Furthermore, given the temporality of some vaccines, the waves of epidemic for two cases are also different. Therefore, our work insight that the way of estimating the perceived risk of infection determines the decision on vaccination options, and then determines the success or failure of control strategy.
The Voluntary Reporting of Greenhouse Gases Program, required by Section 1605(b) of the Energy Policy Act of 1992, records the results of voluntary measures to reduce, avoid, or sequester greenhouse gas emissions. In 1998, 156 US companies and other organizations reported to the Energy information Administration that, during 1997, they had achieved greenhouse gas emission reductions and carbon sequestration equivalent to 166 million tons of carbon dioxide, or about 2.5% of total US emissions for the year. For the 1,229 emission reduction projects reported, reductions usually were measured by comparing an estimate of actual emissions with an estimate of what emissions would have been had the project not been implemented.
The Voluntary Reporting Program, developed pursuant to Section 1605(b) of the Energy Policy Act of 1992, permits corporations, government agencies, households, and voluntary organizations to report on their emissions of greenhouse gases, and on actions taken that have reduced or avoided emissions or sequestered carbon, to the Energy Information Administration (EIA). This, the second annual report of the Voluntary Reporting Program, describes information provided by the participating organizations on their aggregate emissions and emissions reductions, as well as their emissions reduction or avoidance projects, through 1995. This information has been compiled into a database that includes reports from 142 organizations and descriptions of 967 projects that either reduced greenhouse gas emissions or sequestered carbon. Fifty-one reporters also provided estimates of emissions, and emissions reductions achieved, for their entire organizations. The projects described actions taken to reduce emissions of carbon dioxide from energy production and use; to reduce methane and nitrous oxide emissions from energy use, waste management, and agricultural processes; to reduce emissions of halocarbons, such as CFCs and their replacements; and to increase carbon sequestration.

Various factors influence the development of the voluntary 'green' power market--the market in which consumers purchase or produce power from non-polluting, renewable energy sources. These factors include climate policies, renewable portfolio standards (RPS), renewable energy prices, consumers' interest in purchasing green power, and utilities' interest in promoting existing programs and in offering new green options. This report presents estimates of voluntary market demand for green power through 2015 that were made using historical data and three scenarios: low-growth, high-growth, and negative-policy impacts. The resulting forecast projects the total voluntary demand for renewable energy in 2015 to range from 63 million MWh annually in the low case scenario to 157 million MWh annually in the high case scenario, representing an approximately 2.5-fold difference. The negative-policy impacts scenario reflects a market size of 24 million MWh. Several key uncertainties affect the results of this forecast, including uncertainties related to growth assumptions, the impacts that policy may have on the market, the price and competitiveness of renewable generation, and the level of interest that utilities have in offering and promoting green power products.

The aim of the present study was to determine the effects of voluntary breathing on corticospinal excitability of a leg muscle during isometric contraction. Seven subjects performed 5-s isometric knee extension at the intensity of 10% of maximal voluntary contraction (10% MVC). During the 10% MVC, the subjects were instructed to breath normally (NORM) or to inhale (IN) or exhale (OUT) once as fast as possible. Motor-evoked potentials (MEPs) induced by transcranialmagnetic stimulation in the right vastus lateralis (VL) during the 10% MVC were recorded and compared during the three breathing tasks. MEPs in IN and OUT were significantly higher than that in NORM. Effort sense of breathing was significantly higher in IN and OUT than in NORM. There was a significant positive correlation between MEP and effort sense of breathing. These results suggest that activation of the breathing-associated cortical areas with voluntary breathing is involved in the increase in corticospinal excitability of the VL during isometric contraction.

German psychiatry and pharmacology both enjoyed an extraordinary international reputation prior to the promulgation of the Third Reich. However, with the triumph of eugenic ideas and the imposition of a "racial hygiene" policy by the Nazi regime, various organs of the German health system saw themselves involved in a perverse system of social control, in which the illicit use of psychopharmacological tools became customary. In the present work, we review, from the historical perspective, the factors that helped to bring about this situation and we analyze the abuses (known and documented) committed through the specific use of psychotropic drugs during the Nazi period. Among such abuses we can identify the following illegitimate activities: the use of psychoactive drugs, mainly sedatives from the barbiturates family, in the different euthanasia programmes implemented by the Nazi authorities, in police activity and various types of repression, and for purely criminal and extermination purposes within the so-called "Final Solution"; psychopharmacological research on the mentally ill, without the slightest ethical requirements or legal justification; and the use of psychotropic agents in research on healthy subjects, recruited from concentration camps. Finally, we refer to the role of poisonous nerve agents (tabun, sarin and soman) as instruments of chemical warfare and their development by the German authorities. Many of these activities, though possibly only a small portion of the total - given the destruction of a great deal of documentation just before the end of World War II - came to light through the famous Nuremberg Trials, as well as through other trials in which specific persons were brought to justice unilaterally by individual Allied nations or by the authorities of the new German government after the War.

End-of-life decisions are among the most difficult to make or study. When we examined these decisions made under the auspices and protection of stringent state laws, we found no gender bias among patients who chose to end their lives in the face of documented debilitating and terminal diseases. However, in the case of euthanasia as practiced by Jack Kevorkian, we found significant statistical bias against women. Moreover, other data have questioned whether all of Kevorkian's patients did, in fact, have debilitating and terminal illnesses. In this article, we explore why a gender disparity exists in end-of-life decision making. We conclude that if physician-assisted suicide and euthanasia are to be integrated into any end-of-life medical care policy, stringent legal and medical safeguards will be required. Institution of these safeguards should prevent selection bias in a vulnerable population hastening death for reasons other than medically justifiable conditions or issues of individual autonomy, and should ensure that end-of-life decisions are truly reflective of competent personal choice, free from economic considerations or societal pressure.

Fish display robust neuroendocrine and physiologic stress responses to noxious stimuli. Many anesthetic, sedative, or analgesic drugs used in other vertebrates reduce stress in fish, decrease handling trauma, minimize movement and physiologic changes in response to nociceptive stimuli, and can be used for euthanasia. But extrapolating from limited published anesthetic and sedative data to all fish species is potentially harmful because of marked anatomic, physiologic, and behavioral variations; instead, a stepwise approach to anesthetizing or sedating unfamiliar species or using unproven drugs for familiar species is advisable. Additionally, knowledge of how water quality influences anesthesia or sedation helps limit complications. The most common method of drug administration is through immersion, a technique analogous to gaseous inhalant anesthesia in terrestrial animals, but the use of injectable anesthetic and sedative agents (primarily intramuscularly, but also intravenously) is increasing. Regardless of the route of administration, routine preprocedural preparation is appropriate, to stage both the animals and the supplies for induction, maintenance, and recovery. Anesthetic and sedation monitoring and resuscitation are similar to those for other vertebrates. Euthanasia is most commonly performed using an overdose of an immersion drug but injectable agents are also effective. Analgesia is an area in need of significant research as only a few studies exist and they provide some contrasting results. However, fish have mu and kappa opiate receptors throughout the brain, making it reasonable to expect some effect of at least opioid treatments in fish experiencing noxious stimuli.
Euthanasia/assisted dying, the desire to hasten death, and religious supportive care at the end of life are controversial issues that have been heavily debated within the academic and medical communities. Little research has been done on hospice patients' views, despite hospices being political spaces, espousing a range of perspectives on assisted dying, religiosity, and "good deaths." In this article I document the presence, articulation, and significance of these issues as perceived and experienced by 20 hospice inpatients in the last 4 weeks of their lives. Key themes to emerge included polarization in desire for hastened death and assisted dying in the hospice; the hospice as a morally bound space situated within particular notions of "dying well"; and the divisive character of religion as part of formalized hospice care. Theoretically, the participants' perspectives on euthanasia/assisted dying and religiosity in the hospice provide a means of unpacking and revealing the moral economy of modern dying practices and the institutional governance and production of "timely deaths."

The connection between systematic killing of the mentally ill and disabled, euphemistically called "euthanasia" in the National Socialism ideology, and German brain research has been thoroughly investigated and in detail; however, the impact of this criminal nexus on the image and self-perception of German neurologists as well as the status of neurology as a medical discipline is still the subject of controversial debates.Between 1939 and 1945 the Kaiser Wilhelm Institute (KWI) in Berlin along with other research centres were insofar enmeshed in the "euthanasia" program as brains of killed patients were dissected in the guise of "concomitant research" in order to generate medical knowledge. Affected were mainly individuals suffering from oligophrenia, early childhood brain atrophy, cerebral palsy and epilepsy. According to current historical research, collegial networks were instrumental in receiving brains of killed patients. Furthermore, civil research units were supplemented by military ones at the KWI. These, too, were concerned with the collection of medical knowledge, for instance on injuries of the brain and spinal cord. The historical approach to consider the Nazi organizations and medicine as "resources for each other" seems, therefore, at least in part applicable to neurology.

On February 6th 2015 the Supreme Court of Canada (SCC) released their decision on Carter v Canada (Attorney General) to uphold a judgment from a lower court which determined that the current prohibition in Canada on physician-assisted dying violated the s. 7 [Charter of Rights and Freedoms] rights of competent adults whose medical condition causes intolerable suffering. The purpose of this piece is to briefly examine current regulations from Oregon (USA), Belgium, and the Netherlands, in which physician-assisted death and/or euthanasia is currently permitted, as well as from the province of Quebec which recently passed Bill-52, "An Act Respecting End-of-Life Care." We present ethical considerations that would be pertinent in the development of policies and regulations across Canada in light of this SCC decision: patient and provider autonomy, determining a relevant decision-making standard for practice, and explicating challenges with the SCC criteria for assisted-death eligibility with special consideration to the provision of assisted-death, and review of assisted-death cases. [It is not the goal of this paper to address all questions related to the regulation and policy development of euthanasia and assisted death in Canada, but rather to stimulate and guide the conversations in these areas for policy makers, professional bodies, and regulators.].

We have investigated a situation in which externally available response alternatives and their internal representations could be dissociated, by suddenly removing some action alternatives from the response space during the interval between the free selection and the execution of a voluntary action. Choice reaction times in this situation were related to the number of initially available response alternatives, rather than to the number of alternatives available effectively available after the change in the external environment. The internal representations of response alternatives appeared to persist after external changes actually made the corresponding action unavailable. This suggests a surprising dynamics of voluntary action representations: counterfactual response alternatives persist, and may even be actively maintained, even when they are not available in reality. Our results highlight a representational basis for the counterfactual course of action. Such representations may play a key role in feelings of regret, disappointment, or frustration. These feelings all involve persistent representation of counterfactual response alternatives that may not actually be available in the environment. PMID:23653608

A critical application of metabolomics is the evaluation of tissues, which are often the primary sites of metabolic dysregulation in disease. Laboratory rodents have been widely used for metabolomics studies involving tissues due to their facile handing, genetic manipulability and similarity to most aspects of human metabolism. However, the necessary step of administration of anesthesia in preparation for tissue sampling is not often given careful consideration, in spite of its potential for causing alterations in the metabolome. We examined, for the first time using untargeted and targeted metabolomics, the effect of several commonly used methods of anesthesia and euthanasia for collection of skeletal muscle, liver, heart, adipose and serum of C57BL/6J mice. The data revealed dramatic, tissue-specific impacts of tissue collection strategy. Among many differences observed, post-euthanasia samples showed elevated levels of glucose 6-phosphate and other glycolytic intermediates in skeletal muscle. In heart and liver, multiple nucleotide and purine degradation metabolites accumulated in tissues of euthanized compared to anesthetized animals. Adipose tissue was comparatively less affected by collection strategy, although accumulation of lactate and succinate in euthanized animals was observed in all tissues. Among methods of tissue collection performed pre-euthanasia, ketamine showed more variability compared to isoflurane and pentobarbital. Isoflurane induced elevated liver aspartate but allowed more rapid initiation of tissue collection. Based on these findings, we present a more optimal collection strategy mammalian tissues and recommend that rodent tissues intended for metabolomics studies be collected under anesthesia rather than post-euthanasia.

This study (N = 37 with high, medium, and low hypnotizables) evaluated depth reports and EEG activity during both voluntary and hypnotically induced left-arm lifting with sLORETA functional neuroimaging. The hypnotic condition was associated with higher activity in fast EEG frequencies in anterior regions and slow EEG frequencies in central-parietal regions, all left-sided. The voluntary condition was associated with fast frequency activity in right-hemisphere central-parietal regions and slow frequency activity in left anterior regions. Hypnotizability did not have a significant effect on EEG activity, but hypnotic depth correlated with left hemisphere increased anterior slow EEG and decreased central fast EEG activity. Hypnosis had a minimal effect on depth reports among lows, a moderate one among mediums, and a large one among highs. Because only left-arm data were available, the full role of the hemispheres remains to be clarified.

When we actively interact with the environment, it is crucial that we perceive a precise temporal relationship between our own actions and sensory effects to guide our body movements. Thus, we hypothesized that voluntary movements improve perceptual sensitivity to the temporal disparity between auditory and movement-related somatosensory events compared to when they are delivered passively to sensory receptors. In the voluntary condition, participants voluntarily tapped a button, and a noise burst was presented at various onset asynchronies relative to the button press. The participants made either “sound-first” or “touch-first” responses. We found that the performance of temporal order judgment (TOJ) in the voluntary condition (as indexed by the just noticeable difference (JND)) was significantly better (M = 42.5 ms ± 3.8 SEM) than that when their finger was passively stimulated (passive condition: M = 66.8 ms ± 6.3 SEM). We further examined whether the performance improvement with voluntary action can be attributed to the prediction of the timing of the stimulation from sensory cues (sensory-based prediction), kinesthetic cues contained in voluntary action, and/or to the prediction of stimulation timing from the efference copy of the motor command (motor-based prediction). When three noise bursts were presented before the target burst with regular intervals (predictable condition) and when the participant’s finger was moved passively to press the button (involuntary condition), the TOJ performance was not improved from that in the passive condition. These results suggest that the improvement in sensitivity to temporal disparity between somatosensory and auditory events caused by the voluntary action cannot be attributed to sensory-based prediction and kinesthetic cues. Rather, the prediction from the efference copy of the motor command would be crucial for improving the temporal sensitivity. PMID:28018189

Learning new motor skills has been correlated with increased cortical excitability. In this study, different location of electrical stimulation (ES), nerve, or muscle, was paired with voluntary movement to investigate if ES paired with voluntary movement (a) would increase the excitability of cortical projections to tibialis anterior and (b) if stimulation location mattered. Cortical excitability changes were quantified using motor evoked potentials (MEPs) elicited by transcranial magnetic stimulation (TMS) at varying intensities during four conditions. Twelve healthy subjects performed 50 dorsiflexions at the ankle during nerve or muscle ES at motor threshold (MTh). ES alone was delivered 50 times and the movement was performed 50 times. A significant increase in the excitability from pre- to post-intervention (P = 0.0061) and pre- to 30 min post-intervention (P = 0.017) measurements was observed when voluntary movement was paired with muscle ES located at tibialis anterior. An increase of 50 ± 57 and 28 ± 54% in the maximum MEPs was obtained for voluntary movement paired with muscle-located and nerve-located ES, respectively. The maximum MEPs for voluntary movement alone and muscle-located ES alone were −5 ± 28 and 2 ± 42%, respectively. Pairing voluntary movement with muscle-located ES increases excitability of corticospinal projections of tibialis anterior in healthy participants. This finding suggests that active participation during muscle-located ES protocols increases cortical excitability to a greater extent than stimulation alone. The next stage of this research is to investigate the effect in people with stroke. The results may have implications for motor recovery in patients with motor impairments following neurological injury. PMID:27733823

Hallucinations, mental imagery, synesthesia, perceptual filling-in, and many illusions are conscious visual experiences without a corresponding retinal stimulus: what we call 'phantom perception'. Such percepts show that our experience of the world is not solely determined by direct sensory input. Some phantom percepts are voluntary, whereas others are involuntarily, occurring automatically. Here, by way of review, we compare and contrast these two types of phantom perception and their neural representations. We propose a dichotomous framework for phantom vision, analogous to the subtypes of attention: endogenous and exogenous. This framework unifies findings from different fields and species, providing a guide to study the constructive nature of conscious sensory perception.
