To determine whether modern medicine is facilitating 'good' deaths, appropriate measures of the quality of dying and death must be developed and utilized. The purpose of this paper is to identify ...quality of dying and death measurement tools and to determine their quality. MEDLINE (1950-2008), Healthstar (1966-2008), and CINAHL (1982-2008) were searched using keyword terms 'quality of dying/death' and 'good/bad death'. Papers that described a quality of dying and death measure or that aimed to measure the quality of dying and death were selected for review. The evaluation criteria included a description of the measure development (validated or ad hoc), the provision of a definition of quality of dying and death, an empirical basis for the measure, the incorporation of multiple domains and the subjective nature of the quality of dying and death construct, and responsiveness to change. Eighteen measures met the selection criteria. Six were published with some description of the development process and 12 were developed ad hoc. Less than half were based on an explicit definition of quality of dying and death and even fewer relied on a conceptual model that incorporated multidimensionality and subjective determination. The specified duration of the dying and death phase ranged from the last months to hours of life. Of the six published measures reviewed, the Quality of Dying and Death questionnaire (QODD) is the most widely studied and best validated. Strategies to measure the quality of dying and death are becoming increasingly rigorous. Further research is required to understand the factors influencing the ratings of the quality of dying and death. Adapted from the source document.
IDDM and eating disorders are common conditions in young women. Whether a specific association exists between these two disorders remains controversial. Some studies have suggested an increased ...incidence of eating disorders in young women with IDDM, whereas others have not detected such an increase. These differences may be attributable, at least in part, to methodological issues in study design, measurement tools, and relatively small sample sizes. Whether the prevalence of eating disorders in IDDM is increased will be resolved only by larger studies that use standardized diagnostic interviews. We suspect that certain aspects of IDDM and its management may trigger the expression of an eating disorder in susceptible individuals. Required dietary restraint and weight gain related to diabetes management are the factors most likely to be implicated. Eating disorders are relatively common in young women with IDDM and may contribute to impaired metabolic control with hypoglycemia and DKA, and to long-term microvascular complications of diabetes. Omission or reduction of required insulin, an extremely common means of weight control in these young women, is likely an important factor in this regard. Further research is required to determine more precisely the relationship between IDDM and eating disorders, and the effects of eating disorders on metabolic control and chronic complications of IDDM.

What is the efficacy of pharmacologic and non-pharmacologic treatments for major depression and other depressive disorders in cancer populations?
Depression occurs at an increased rate in medically ...ill populations, including patients with cancer. In the general population, depression has been shown to be responsive to structured forms of psychotherapy and to pharmacologic interventions. The Supportive Care Guidelines Group conducted a systematic review of the evidence for the effectiveness of those therapies in patients with depression and cancer and developed the present clinical practice guideline based on that review and on expert consensus.
Outcomes of interest included symptomatic response to treatment, discontinuation rate of treatment, adverse effects, and quality of life.
Clinical recommendations were developed by the Supportive Care Guidelines Group based on a systematic review of the published literature through June 2005, feedback obtained from Ontario health care providers on the draft recommendations, the Report Approval Panel (rap) of Cancer Care Ontario's Program in Evidence-Based Care, and expert consensus.
The systematic review of the literature included eleven trials (seven of pharmacologic agents and four of non-pharmacologic interventions). Feedback received from 44 responding health care providers and the rap on the draft recommendations was addressed and documented in the guideline. Among providers, 82% agreed with the draft recommendations as stated, 68% agreed that the report should be approved as a practice guideline, and 73% indicated that they would be likely to use the guideline in their own practice.
These recommendations apply to adult cancer patients with a diagnosis of major depression or other non-bipolar depressive disorders. They do not address the treatment of non-syndromal depressive symptoms, for which specific antidepressant treatment is not usually indicated. The guideline is intended both for oncology health professionals and for mental health professionals engaged in the treatment of cancer patients. Expert consensus was central to the development of the guideline recommendations because of limited evidence in cancer patients.
Treatment of pain and other reversible physical symptoms should be instituted before or with initiation of specific antidepressant treatment. Antidepressant medications should be considered for the treatment of moderate-to-severe major depression in cancer patients. Current evidence does not support the relative superiority of one pharmacologic treatment over another, nor the superiority of pharmacologic treatment over psychosocial interventions. The choice of an antidepressant should be informed by individual medication and patient factors: the side effect profiles of the medication, tolerability of treatment (including the potential for interaction with other current medications), response to prior treatment, and patient preference. Cancer patients diagnosed with major depression may benefit from a combined modality approach that includes both psychosocial and pharmacologic interventions. Psychosocial treatment approaches that may be of value include those that provide information and support and those that address any combination of emotional, cognitive, and behavioural factors.
Referral to a mental health specialist is appropriate when the diagnosis of depression is unclear, when the syndrome is severe, when patients do not respond to treatment, or when other complicating factors that may affect the choice of treatment are present. Although care has been taken in the preparation of the information contained in this guideline, any person seeking to apply or to consult the guideline is expected to use independent medical judgment in the context of individual clinical circumstances or to seek out the supervision of a qualified clinician.
The quality of reconstructed impulse response of holograms displayed on a three DMD modulators of different models was experimentally evaluated. The integral parameter of modulators' optical quality ...- the size of sufficiently flat area of matrix surface - was estimated according to the developed technique. The results of holograms reconstruction are analyzed.
Within the framework of two-dimensional potential theory, we consider problems defined on slender domains. The boundary element matrices for such problems are poorly conditioned due to the presence ...of two disparate length scales. A new class of preconditioners is proposed to remedy this problem so that the preconditioned boundary element matrices become insensitive to the domain slenderness. The preconditioners are constructed using the spectral properties of the boundary integral operators defined on the elliptical domains.

Abstract A substantial minority of patients in palliative care settings report a high desire for hastened death (DHD), in association with physical and emotional distress, low social support, and ...impaired spiritual well being. To clarify to what extent DHD emerges in association with suffering prior to the end of life, we determined its prevalence and correlates in ambulatory patients with metastatic cancer, the majority of whom had an expected survival of >6 months. We hypothesized that DHD in this sample would be directly linked to physical and psychological distress, and inversely related to perceived social support, self-esteem, and spiritual well being. Three hundred twenty-six outpatients completed the Schedule of Attitudes Toward Hastened Death (SAHD), Brief Pain Inventory, Memorial Symptom Assessment Scale, Beck Depression Inventory-II (BDI-II), Beck Hopelessness Scale (BHS), Medical Outcomes Study Social Support Survey, FACIT-Spiritual Well-Being Scale, Rosenberg Self-Esteem Scale, and Karnofsky Performance Status. Over 50% of participants reported pain, >20% reported elevated levels of depression (BDI-II ≥ 15) and hopelessness (BHS ≥ 8), but <2% had a high DHD (SAHD ≥ 10). DHD was correlated positively with hopelessness, depression, and physical distress, and negatively with physical functioning, spiritual well being, social support, and self-esteem; it was not associated with treatment status or proximity to death. Over 34% of the variance in predicting SAHD scores was accounted for by hopelessness, depression, and functional status. The relative absence of a strong DHD in this sample suggests that the will to live tends to be preserved in cancer patients prior to the end of life, in spite of significant emotional and physical suffering.
Depressive symptoms and syndromes are common in the medically ill, although they are frequently unrecognized and untreated. The authors review the epidemiology, differential diagnosis, clinical ...presentations, and response to treatment of this clinical problem. They address such methodological issues in the current literature in this area as the advantages and limitations of standardized assessment measures and discuss treatment modalities for depression in the medically ill, including antidepressant medication and ECT. This clinical problem warrants attention for a variety of reasons: its prevalence, associated morbidity, and treatability. Elucidation of the mechanisms of depression in the medically ill may also contribute to a broader understanding of depression in other populations.
