Why Weight? An Analytic Review of Obesity Management, Diabetes Prevention, and Cardiovascular Risk Reduction.

PURPOSE OF REVIEW: In this review, we examine one of the ironies of American health care-that we pay more for disease management than disease prevention. Instead of preventing type 2 diabetes (T2DM) by treating its precursor, obesity, we fail to provide sufficient insurance coverage for weight management only to fund the more costly burden of overt T2DM. RECENT FINDINGS: There is a vital need for expanded insurance coverage to help foster a weight-centric approach to T2DM management. This includes broader coverage of anti-diabetic medications with evidence of cardiovascular risk reduction and mortality benefit, anti-obesity pharmacotherapy, bariatric surgery, weight loss devices, endoscopic bariatric therapies, and lifestyle interventions for the treatment of obesity. The fundamental question to ask is why weight? Why wait to go after obesity until its end-stage sequelae cause intractable conditions? Instead of managing the complications of T2DM, consider preventing them by tackling obesity.

The internist as clinical ethics consultant: An antidote to "the barbarism of specialisation" in hospital practice. / El internista como consultor de ética clínica: un antídoto contra «la barbarie del especialismo¼ en la práctica hospitalaria.

The development of hospital clinical ethics in Spain depends almost exclusively on the healthcare ethics committees, which have been criticized for a lack of proximity to the patient's bedside in day-to-day ethical conflicts and for their scarce practical operation, reflected in the low number of consultations they receive. In this study, we reflect on the need to change the current healthcare model in clinical ethics so as to reactivate it and call attention to the essential role of internists as the engine for this change. To this end, we propose a model in which the healthcare ethics committees incorporate ethics consultants, who are better positioned to discuss cases at the patient's bedside. We then analyse the characteristics that these consultants should have.

Behavioural improvements with thalamic stimulation after severe traumatic brain injury.

Widespread loss of cerebral connectivity is assumed to underlie the failure of brain mechanisms that support communication and goal-directed behaviour following severe traumatic brain injury. Disorders of consciousness that persist for longer than 12 months after severe traumatic brain injury are generally considered to be immutable; no treatment has been shown to accelerate recovery or improve functional outcome in such cases. Recent studies have shown unexpected preservation of large-scale cerebral networks in patients in the minimally conscious state (MCS), a condition that is characterized by intermittent evidence of awareness of self or the environment. These findings indicate that there might be residual functional capacity in some patients that could be supported by therapeutic interventions. We hypothesize that further recovery in some patients in the MCS is limited by chronic underactivation of potentially recruitable large-scale networks. Here, in a 6-month double-blind alternating crossover study, we show that bilateral deep brain electrical stimulation (DBS) of the central thalamus modulates behavioural responsiveness in a patient who remained in MCS for 6 yr following traumatic brain injury before the intervention. The frequency of specific cognitively mediated behaviours (primary outcome measures) and functional limb control and oral feeding (secondary outcome measures) increased during periods in which DBS was on as compared with periods in which it was off. Logistic regression modelling shows a statistical linkage between the observed functional improvements and recent stimulation history. We interpret the DBS effects as compensating for a loss of arousal regulation that is normally controlled by the frontal lobe in the intact brain. These findings provide evidence that DBS can promote significant late functional recovery from severe traumatic brain injury. Our observations, years after the injury occurred, challenge the existing practice of early treatment discontinuation for patients with only inconsistent interactive behaviours and motivate further research to develop therapeutic interventions.

Gene therapy ethics and haemophilia: an inevitable therapeutic future?

Haemophilia was recognized early on as an ideal candidate for a gene transfer approach to therapy. In the past decade, gene transfer experimentation in the haemophilias has indeed played an integral role in furthering the science in the global field of gene therapy. However, these expectations have placed haemophilia gene transfer researchers under pressure to succeed in a scientific domain in which successes are infrequent and progress is necessarily slow. These same expectations have also fueled the perception of gene therapy as the inevitable therapeutic goal for the youngest children with haemophilia. In this paper, we will discuss the ethical implications of this perception in light of anticipated benefits, acceptable risk, perceived consumer need and the unknown cost of this intervention. A framework for the future study and therapeutic implementation of gene transfer technology in this specific population is proposed. Public debate on this issue that includes the voices of the intended beneficiaries, especially the parents of the youngest children with haemophilia and the children themselves, is encouraged.

Communication in intensive care settings: the challenge of futility disputes.

In intensive care settings, suboptimal communication can erode family trust and fuel so-called "futility" disputes. Presenting a teaching case used by >225 hospitals participating in the Decisions Near the End-of-Life program, we identify critical communication challenges and opportunities. We emphasize that good communication requires not only clear and sensitive language but also clinician self-awareness, psychological insight, and an institutional culture that promotes good communication with families. The article concludes with two examples of steps institutions can take to foster good communication between families and healthcare professionals.

Gaining insight into the care of hospitalized dying patients: an interpretative narrative analysis.

Narrative ethics is a useful tool for gaining insight into the care of hospitalized dying patients. We used narrative analysis to interpret the medical records of 200 adult deaths at our institution. Prominent subjects which emergedfrom this review include documentation of care; relationships between patients, families and clinicians; and the influence of time, uncertainty, ambiguity, resource allocation, and spirituality on the course of care. Research on narratives can help script more empathic and compassionate care of the dying by demonstrating that every death is a story waiting to be told.

Development of a palliative education assessment tool for medical student education.

Studies assessing palliative care education in U.S. medical schools reveal that little attention is paid to this topic. Although core competencies have been defined, few schools have implemented effective means to incorporate formal palliative care education into undergraduate curricula. To promote reform, each school needs to conduct a thorough assessment to identify palliative care content throughout the four-year curriculum. The authors developed an innovative assessment instrument to facilitate curricular mapping of palliative care education. The Palliative Education Assessment Tool (PEAT) comprises seven palliative care domains: palliative medicine, pain, neuropsychologic symptoms, other symptoms, ethics and the law, patient/family/nonclinical caregiver perspectives on end-of-life care, and clinical communication skills. Each domain details specific curricular objectives of knowledge, skills, and attitudes. Designed as a flexible self-assessment tool, PEAT helps determine the existence of palliative care education, which usually is found in various formats throughout a medical school's curriculum and thus sometimes "hidden." PEAT enables educators to describe a specific, multidimensional aspect of the curriculum and use the information for strategic planning, educational reform, and evaluation. The curricular reform implications of such an instrument are broader than palliative care assessment. A modified version of PEAT can be used to assess systematically other topics that are taught in various formats in the curriculum and to develop collaborative approaches to fulfilling the educational objectives of those topics.

An approach to educating residents about palliative care and clinical ethics.

Despite interest in end-of-life educational efforts, attitudinal barriers still thwart the integration of palliative care into medical education. The authors present their experience introducing a graduate medical education program in ethics and palliative care at New York Presbyterian Hospital and Weill Medical College of Cornell University. Through this initiative the authors sought to enhance residents' knowledge, skills, and attitudes needed for effective palliative care. Residents were targeted because they are in a unique stage of their training; while they have mastered many basic clinical skills they remain open to educational experiences that might alter their lifelong practice patterns. Course material was based upon the residents' experiences. Using their case histories interested them as adult learners and validated the importance of the subject matter. Seminar themes included professionalism, the physician facing death, ethical, legal, cross-cultural, and religious issues at the end of life, and pain and symptom management. The program provided a valuable educational forum for residents to give voice to their reflections and receive supportive feedback from peers and faculty. Building upon the residents' own clinical experiences with end-of-life care effectively engaged their interest and provided much-needed instruction in this evolving area of study.

A proposed ethical framework for interventional cognitive neuroscience: a consideration of deep brain stimulation in impaired consciousness.

Advances in neuromodulation techniques offer the promise of new therapeutic interventions for patients with neuropsychiatric maladies. Several complex social, ethical and policy issues will attend developments in this area. In this paper an ethical framework for clinical research in interventional cognitive neuroscience is advanced. Deep brain stimulation in traumatic brain injury is considered as a paradigm case to examine ethical obligations in human subject research. These include balancing access to novel therapies versus protection of vulnerable study populations, rational evaluation of study design and research strategies, informed consent, and the importance of achieving societal consensus for this line of scientific inquiry.

Clinical pragmatism, ethics consultation, and the elderly patient.

This article describes a process of moral problem solving for medicine termed clinical pragmatism. A structured and disciplined method of addressing ethical problems in medical practice that clinicians will find useful in their daily routines is provided. After outlining the method of clinical pragmatism, the authors illustrate its use in a case involving an older patient refusing medical treatment and conclude with comments on the importance of the process in ethics case consultation.

Assisted suicide compared with refusal of treatment: a valid distinction? University of Pennsylvania Center for Bioethics Assisted Suicide Consensus Panel.

The continuing debate over the deeply controversial issue of physician-assisted suicide has been complicated by confusion about how this practice resembles or differs from refusal of life-sustaining treatment. Perspectives on ethics and policy hinge on the contested issue of whether a valid distinction can be made between assisted suicide and withdrawal of treatment. This paper uses three illustrative cases to examine leading arguments for and against the recognition of a fundamental distinction between these practices. The first case involves assisted suicide by ingestion of prescribed barbiturates, the second involves withdrawal of artificial nutrition and hydration, and the third involves a decision to stop eating and drinking. On theoretical and practical grounds, this paper defends the position that there is a valid distinction between assisted suicide and refusal of treatment.

Enrolling decisionally incapacitated subjects in neuropsychiatric research.

This paper discusses the National Bioethics Advisory Commission's (NBAC's) report on research involving persons with mental disorders that may affect decisionmaking capacity. After placing the NBAC recommendations into their historic context, the authors propose a strategy to enroll decisionally incapacitated subjects into neuropsychiatric research. The authors maintained that their proposed consensus model for research authorization, utilizing subject advocates, fosters valuable clinical research while protecting potentially vulnerable subjects.

Incorporating palliative care into critical care education: principles, challenges, and opportunities.

OBJECTIVE: To identify the goals and methods for medical education about end-of-life care in the intensive care unit (ICU). DATA SOURCES AND STUDY SELECTION: A status report on palliative care, a summary report of recent research on palliative care education, articles in the medical literature on end-of-life care and critical care, and expert opinion were considered. DATA EXTRACTION: A working group, including specialists in critical care, palliative care, medical ethics, consumer advocacy, and communications, was convened at the "Medical Education for Care Near the End of Life National Consensus Conference." A modified nominal group process was used to develop a consensus. DATA SYNTHESIS: In the ICU, life and death decisions are often made in a crisis mode or in the face of uncertainty, and may necessitate the withholding and withdrawal of life-supporting technologies. Because critical illness often diminishes the capacity of patients to make decisions, clinicians must often make decisions in conjunction with surrogates, rather than with patients. Discontinuity of care can threaten trusting relationships, and cultural diversity can have a particularly powerful impact on choices for care. In the face of these realities, it is possible and appropriate to give compassionate palliative care to dying patients and their families in the ICU. CONCLUSIONS: Teaching care of the dying in the ICU should emphasize the following: a) the goals of care should guide the use of technology; b) understanding of prognostication and treatment withholding and withdrawal is essential; c) effective communication and trusting relationships are crucial to good care; d) cultural differences should be acknowledged and respected; and e) the delivery of excellent palliative care is appropriate and necessary when patients die in the ICU.
