Complete Nucleotide Sequence of an Isolate of Grapevine Satellite Virus and Evidence for the Presence of Multimeric Forms in an Infected Grapevine.

The complete nucleotide sequence of an isolate of grapevine satellite virus (GV-Sat) was determined by next-generation sequencing (NGS) and compared with the single available complete sequence. The NGS data unexpectedly provided evidence for the existence of multimeric forms of GV-Sat, which were experimentally confirmed, allowing the redefinition of GV-Sat genomic ends.

Importance of Reaction Kinetics and Oxygen Crossover in aprotic Li-O2 Batteries Based on a Dimethyl Sulfoxide Electrolyte.

Although still in their embryonic state, aprotic rechargeable Li-O2 batteries have, theoretically, the capabilities of reaching higher specific energy densities than Li-ion batteries. There are, however, significant drawbacks that must be addressed to allow stable electrochemical performance; these will ultimately be solved by a deeper understanding of the chemical and electrochemical processes occurring during battery operations. We report a study on the electrochemical and chemical stability of Li-O2 batteries comprising Au-coated carbon cathodes, a dimethyl sulfoxide (DMSO)-based electrolyte and Li metal negative electrodes. The use of the aforementioned Au-coated cathodes in combination with a 1 M lithium bis(trifluoromethane)sulfonimide (LiTFSI)-DMSO electrolyte guarantees very good cycling stability (>300 cycles) by minimizing eventual side reactions. The main drawbacks arise from the high reactivity of the Li metal electrode when in contact with the O2 -saturated DMSO-based electrolyte.

Complete Nucleotide Sequence of Artichoke latent virus Shows it to be a Member of the Genus Macluravirus in the Family Potyviridae.

Complete genomic sequences of Artichoke latent virus (ArLV) have been obtained by classical or high-throughput sequencing for an ArLV isolate from Italy (ITBr05) and for two isolates from France (FR37 and FR50). The genome is 8,278 to 8,291 nucleotides long and has a genomic organization comparable with that of Chinese yam necrotic mosaic virus (CYNMV), the only macluravirus fully sequenced to date. The cleavage sites of the viral polyprotein have been tentatively identified by comparison with CYNMV, confirming that macluraviruses are characterized by the absence of a P1 protein, a shorter and N-terminally truncated coat protein (CP). Sequence comparisons firmly place ArLV within the genus Macluravirus, and confirm previous results suggesting that Ranunculus latent virus (RALV), a previously described Macluravirus sp., is very closely related to ArLV. Serological relationships and comparisons of the CP gene and of the partial RaLV sequence available all indicate that RaLV should not be considered as a distinct species but as a strain of ArLV. The results obtained also suggest that the spectrum of currently used ArLV-specific molecular hybridization or polymerase chain reaction detection assays should be improved to cover all isolates and strains in the ArLV species.

[Ethical case discussions in the intensive care unit : from testing to routine]. / Ethische Fallbesprechungen auf der Intensivstation : Vom Versuch zur Routine.

BACKGROUND: The daily work of many healthcare professionals has become more complex and demanding in recent years. Apart from purely medical issues, ethical questions and problems arise quite often. Managing these problems requires ethical knowledge. Questions about the usefulness of a therapy and treatment occur especially at the end of life. So-called medical futility, a useless futile therapy, is often perceived by nurses and physicians in intensive care units who themselves often develop symptoms of depression or burnout. The clinical ethical model METAP (acronym from module, ethics, therapy decision, allocation and process) provides methods and criteria that allow the clinical team to treat and solve ethical issues according to a solution-oriented approach. The ethical decision-making of this model addresses these issues according to a series of sequential stages in the form of a so-called escalation model. When it is not possible to tackle and solve an ethical problem or dilemma in one stage, one moves to the next. The implementation of this approach in everyday practice requires the commitment of all team members in addition to certain basic conditions. MATERIAL AND METHODS: In a surgical intensive care unit a fixed date in the schedule is reserved for ethical case discussions (level 3 of the escalation model). At this level a team member who has been specified according to a quarterly plan is responsible for the organization and performance of the discussion. All protocols of the 44 ethical case discussions in 41 patients between January 2011 and July 2012 were collected and summarized. A short questionnaire to all participants recorded their assessment of the benefits for the patient and the team as well as their perception of personal stress reduction. Also queried was the impact of this method on the collaboration between nurses and physicians and the ethical competence. RESULTS: Ethical case discussions among the care team took place regularly (44 case discussions between January 2011 and June 2012). The duration of these discussions ranged from 30 to 60 min. On average 6.2 persons took part, including 2.7 nurses and 3.2 physicians. Of the 41 patients (16 female, 25 male) for whom a discussion was carried out, 23 died during the continued hospital stay. The respondents (response rate 52 %) assessed the benefit for patients and team as high (slightly higher benefit for physicians than nurses) and 55 % of physicians and 71 % of nurses perceived a reduction in the burden of decision-making in difficult cases due to the case discussions. All physicians and 66 % of the nurses reported an improvement in the cooperation between the professional groups and 80 % of the nurses and more than half of the physicians noticed an increase in their own ethical competence. CONCLUSION: A methodically structured ethical decision-making process can and should be integrated into the clinical routine. This process requires a fixed place in everyday practice and the defined responsibility for the actual organization and performance. Support by medical and nursing management personnel is also essential for the implementation. The regular occurrence of ethical case discussions among the care team relieves the participants and improves collaboration between nurses and physicians.

[Clinical everyday ethics-support in handling moral distress? : Evaluation of an ethical decision-making model for interprofessional clinical teams]. / Klinische Alltagsethik - Unterstützung im Umgang mit moralischem Disstress? : Evaluation eines ethischen Entscheidungsfindungsmodells für interprofessionelle klinische Teams.

BACKGROUND: High-tech medicine and cost rationing provoke moral distress up to burnout syndromes. The consequences are severe, not only for those directly involved but also for the quality of patient care and the institutions. The multimodal model METAP (Modular, Ethical, Treatment, Allocation, Process) was developed as clinical everyday ethics to support the interprofessional ethical decision-making process. The distinctive feature of the model lays in education concerning ethics competence in dealing with difficult treatment decisions. METAP has been evaluated for quality testing. METHODS: The research question of interest was whether METAP supports the handling of moral distress. The evaluation included 3 intensive care units and 3 geriatric units. In all, 33 single and 9 group interviews were held with 24 physicians, 44 nurses, and 9 persons from other disciplines. An additional questionnaire was completed by 122 persons (return rate 57%). RESULTS: Two-thirds of the interview answers and 55% of the questionnaire findings show that clinical everyday ethics supports the handling of moral distress, especially for interdisciplinary communication and collaboration and for the explanation and evaluation of treatment goals. METAP does not provide support for persons who are rarely confronted with ethical problems or have not applied the model long enough yet. CONCLUSION: To a certain degree, moral distress is unavoidable and must be addressed as an interprofessional problem. Herein, clinical everyday ethics may provide targeted support for ethical decision-making competence.

The role of relatives in decisions concerning life-prolonging treatment in patients with end-stage malignant disorders: informants, advocates or surrogate decision-makers?

BACKGROUND: This study examines the extent to which relatives of severely ill cancer patients are involved in the decision to limit treatment (DLT), their role in communicating patient wishes and the incidence of and reasons for disagreement with relatives. PATIENTS AND METHODS: This cohort study followed 70 patients with terminal cancer, for whom a limitation of life-prolonging treatment was being considered. 'Embedded researchers' recorded patients' wishes and the relatives' roles and disagreements with DLT. RESULTS: Although 63 out of 70 patients had relatives present during their care, only 32% of relatives were involved in DLT. Physicians were more likely to know the end-of-life (EOL) preferences for those patients who had visiting relatives than those without them (78% versus 29%, P = 0.014). Most relatives supported patients in voicing their preferences (68%), but one-third acted against the known or presumed wishes of patients (32%). Disagreements with patients' relatives occurred in 21% of cases, and predominantly when relatives held views that contradicted known patient preferences (71% versus 7%, P = 0.001). CONCLUSION: If relatives are to play an important part in EOL decision making, we must devise strategies to recognise their potential as patients' advocates as well as their own needs.

[Futility: a concept in routine surgery?]. / Futility: ein Begriff im chirurgischen Alltag?

In surgical practice we are often confronted with ethically challenging situations when treating patients not capable of expressing their own wishes. Issues of futile treatment by indicating operations arise particularly with regard to severe dementia. The concept of futility describes forms of therapy which are not appropriate to improve the patient's condition, but for application in clinical practice the concept is insufficiently defined.In ethically challenging situations, e.g. in the treatment of severely demented patients, we need to balance the medical condition and prognosis with the documented or assumed wishes of the patients. Involving the relatives competently is essential. The indication for surgery in patients with severe dementia, for example, needs to be individualized striving for optimal care, a clear communication about treatment goals with the relatives and preventing distress and burnout for staff. Co-operation with specialists in medical ethics is recommended.

Should ethics consultants help clinicians face scarcity in their practice?

In an international survey of rationing we have found that European physicians encounter scarcity-related ethical difficulties, and are dissatified with the resolution of many of these cases. Here we further examine survey results to explore whether ethics support services would be potentially useful in addressing scarcity related ethical dilemmas. Results indicate that while the type of help offered by ethics support services was considered helpful by physicians, they rarely referred difficulties regarding scarcity to ethics consultation. We propose that ethics consultants could assist physicians by making the process less difficult, and by contributing to decisions being more ethically justifiable. Expertise in bringing considerations of justice to bear on real cases could also be useful in recognising an unjust limit, as opposed to a merely frustrating limit. Though these situations are unlikely to be among the most frequently referred to ethics support services, ethics consultants should be prepared to address them.

[Ethic charter of the German Society for the Study of Pain (DGSS)]. / Ethik-Charta der Deutschen Gesellschaft zum Studium des Schmerzes (DGSS).

The German Society for the Study of Pain has formed an interdisciplinary committee to answer urgent ethical questions on the diagnosis and treatment of pain and to give an ethical orientation on the care of pain and palliative patients. The treatment of pain is a fundamental objective of medicine. Competent and adequate relief of pain in all stages of life is a basic characteristic of a humane medicine oriented to the quality and meaning of life for people. However, there are substantial deficits in all areas, especially in the knowledge of physicians and patients, in training and further education, diagnosis and therapy. Freedom from pain is a substantial element of quality of life. A central duty of all physicians is an adequate diagnosis and treatment of acute pain and thereby the prophylaxis of chronic pain. If pain persists over a longer period of time, it loses the warning function and becomes taken for granted. Alterations, disabilities and limitations of the physical, psychic and social levels are the consequences. For these patients an interdisciplinary approach is necessary by which various medical disciplines, psychologists and physiotherapists are involved and all collaborate on the diagnosis and therapy of pain. All patients have the right to sufficient and individually tailored treatment of pain. Special attention must be paid to vulnerable patient groups, such as newborns, children and adolescents, as well as aged and mentally retarded patients. For cancer patients pain relief of their tumor pain is totally in the forefront. Indications of "unbearable pain" must not lead to resignation or even be seen as an argument for legalization of "death on request". The nursing of terminally ill patients necessitates a special measure not only of clinical, but also ethical competence, communication and multiprofessional collaboration. The modern options for palliative care are real alternatives to demands for legalization of "death on request". Physician-assisted suicide does not belong to the scope of functions of palliative medicine. The basic constitutional law makes an appropriate treatment of pain obligatory. Neglect of pain treatment fulfils the elements of criminal bodily harm. As a consequence, there is a legal right to a comprehensive pain diagnosis and a pain treatment corresponding to the appropriate standard. The state is obliged to provide the legal, social and financial prerequisites for an adequate treatment of pain. Continuous efforts in research are necessary to fill the existing gaps in our knowledge. The transfer between basic research and clinical application of pain therapy must be urgently improved. Of central importance for the German Pain Society are therefore: Improvement of training and further education in pain therapy. Chronic pain must be accepted and coded as an autonomous sickness. Graded structures for care of pain patients must be realized. Interdisciplinary structures of care must be made available to patients with chronic pain. Palliative medical care is a basic right of all terminally ill patients. Politics and health care providers must establish prerequisites for adequate pain diagnosis, pain therapy and palliative medicine.

Ethical difficulties in clinical practice: experiences of European doctors.

BACKGROUND: Ethics support services are growing in Europe to help doctors in dealing with ethical difficulties. Currently, insufficient attention has been focused on the experiences of doctors who have faced ethical difficulties in these countries to provide an evidence base for the development of these services. METHODS: A survey instrument was adapted to explore the types of ethical dilemma faced by European doctors, how they ranked the difficulty of these dilemmas, their satisfaction with the resolution of a recent ethically difficult case and the types of help they would consider useful. The questionnaire was translated and given to general internists in Norway, Switzerland, Italy and the UK. RESULTS: Survey respondents (n=656, response rate 43%) ranged in age from 28 to 82 years, and averaged 25 years in practice. Only a minority (17.6%) reported having access to ethics consultation in individual cases. The ethical difficulties most often reported as being encountered were uncertain or impaired decision-making capacity (94.8%), disagreement among caregivers (81.2%) and limitation of treatment at the end of life (79.3%). The frequency of most ethical difficulties varied among countries, as did the type of issue considered most difficult. The types of help most often identified as potentially useful were professional reassurance about the decision being correct (47.5%), someone capable of providing specific advice (41.1%), help in weighing outcomes (36%) and clarification of the issues (35.9%). Few of the types of help expected to be useful varied among countries. CONCLUSION: Cultural differences may indeed influence how doctors perceive ethical difficulties. The type of help needed, however, did not vary markedly. The general structure of ethics support services would not have to be radically altered to suit cultural variations among the surveyed countries.

The Freiburg approach to ethics consultation: process, outcome and competencies.

The paper describes how ethics consultation can be valuable to health professionals, patients and their families in understanding and evaluating ethical values and their consequences in a particular situation. Ethics consultation as it is practised at the university hospital of Freiburg is a special professional service offered by members of an academic institution. The practical approach and the goals are illustrated by a case study showing the difficulties of deciding about the limitation of intensive care medicine after heart surgery in the setting of maximum treatment. Here, the ethics consultation was initiated by the relatives of the patient who wanted a decision to withhold further life-sustaining treatment. Following the experiences in Freiburg, it is concluded that clinical ethicists have to cover a variety of relevant fields of knowledge, need special analytical skills, and should have professional competence in counselling, including conflict mediation or crisis intervention.

Ethics consultation on demand: concepts, practical experiences and a case study.

Despite the increasing interest in clinical ethics, ethics consultation as a professional service is still rare in Europe. In this paper I refer to examples in the United States. In Germany, university hospitals and medical faculties are still hesitant about establishing yet another "committee". One of the reasons for this hesitation lies in the ignorance that exists here about how to provide medical ethics services; another reason is that medical ethics itself is not yet institutionalised at many German universities. The most important obstacle, however, may be that medical ethics has not yet demonstrated its relevance to the needs of those caring for patients. The Centre for Ethics and Law, Freiburg, has therefore taken a different approach from that offered elsewhere: clinical ethics consultation is offered on demand, the consultation being available to clinician(s) in different forms. This paper describes our experiences with this approach; practical issues are illustrated by a case study.
