A Family Booklet About Comfort Care in Advanced Dementia:Three-Country Evaluation

Objectives: To evaluate a booklet on comfort care in dementia from the perspective of family with relevant experience, and assess nursing home resident and family factors associated with evaluations. Design: Retrospective study. Setting: Long term care facilities in French-speaking Canada, and the Netherlands and Italy.
Participants: Bereaved family (n = 138).
Measurements: An 8-item scale assessed the booklet's acceptability. Usefulness was rated on a 0 to 10 scale, and perceived usefulness referred to usefulness if family had had the booklet during the resident's stay. Families indicated preferred ways of obtaining, and the most appropriate time to get the booklet.
Results: Almost all families (94%) perceived the booklet as useful. Canadian and Dutch families evaluated the booklet's contents and format favorably, whereas Italian families' evaluations were less favorable. Almost all families endorsed roles for physicians or nurses and about half additionally accepted availability through own initiative, in print or through the Internet. Preference of timing was highly variable. Better acceptability, usefulness, and availability through own initiative were independently associated with non-Italian nationality, presence of more physical signs discussed in the booklet, feeling ill-prepared, and higher satisfaction with care. A preference of receiving the booklet early was more likely in Italian families, those without university education, and those involved with older residents.
Conclusion: The booklet is suitable to inform Dutch and Canadian families on comfort care in dementia, but implementation in Italy requires further consideration. The booklet may be integrated in advance care planning in long term care, and made available outside long term care settings to serve families who wish to be informed early. © 2012 American Medical Directors Association, Inc.

Active carers: living with chronic obstructive pulmonary disease

It has long been recognised that the majority of care provided in chronic illness comes not from health and social care professionals, but from family and friends. One such illness is chronic obstructive pulmonary disease (COPD), a leading cause of morbidity and mortality in the developed world.To explore the specific care needs of informal caregivers of patients with advanced COPD, interviews were conducted with seven active family caregivers. Interviews were taped, transcribed and content analysed to obtain the caregivers' needs. Results confirm that family caregivers provide direct care with little support and assistance. Participants reported restricted activities of daily living and some emotional distress. There were knowledge deficiencies among caregivers relating to the COPD illness trajectory and little awareness of the potential of palliative care. Family caregivers need social and professional support while caring for a patient at home. This would help to ensure that their physical and emotional health does not suffer. There is a need to devise interventions to ensure family caregivers are supported.

Internal Limiting Membrane Peeling in Vitreo-retinal Surgery

Peeling the internal limiting membrane of the retina has become a very common procedure performed by vitreo-retinal surgeons. The combination of new microsurgical instrumentation with the availability of different dyes to stain this thin and transparent membrane has facilitated the performance of internal limiting membrane peeling, reducing the time and trauma associated with this maneuver. Internal limiting membrane peeling has been used to treat a variety of retinal pathologies, including full-thickness macular hole, epiretinal membrane, macular edema, vitreomacular traction syndrome, and Terson syndrome, among others. Although it appears that peeling the internal limiting membrane in these retinal conditions may be associated with better anatomical and visual outcomes following surgery, further evidence through randomized controlled clinical trials is still needed to guide the vitreo-retinal surgeon on the appropriate use of this surgical maneuver. © 2008 Elsevier Inc.

Source as a controlling factor on the quality and interpretation of sediment magnetic records from the northern North Atlantic

Magnetic properties of eight particle size ranges from nine locations in Iceland and 26 locations in southern Greenland reveal the importance of source variation for our understanding of paleomagnetic and environmental magnetic records in the marine environment. These terrestrial samples show varying degrees of particle size dependence with all samples showing that the silt fraction possesses greater concentrations of ferrimagnetic minerals than either clay or sand. Fine pseudo-single domain (PSD) size magnetic grains dominate the magnetic assemblage of all Icelandic fractions. In contrast, Greenlandic samples possess greater variation in magnetic grain size; only fine silt and clay are as magnetically fine as the Icelandic PSD grains, while Greenlandic silts and sands are dominated by coarser PSD and multi-domain grains. These observations from potential marine sediment sources suggest that the silt size fraction is a likely driver for much of the concentration-dependent parameters derived from bulk magnetic records and that the magnetic grain size of the silt fraction can be used to discriminate between Icelandic and Greenlandic sources. Using these results to examine magnetic grain size records from marine sediment cores collected across the northern North Atlantic suggests that source, not just transport-controlled physical grain-size, has a significant impact on determining the magnetic grain size at a particular location. Homogeneity of magnetic grain size in Icelandic sediments at least partially explains the consistent quality of paleomagnetic records derived from cores surrounding Iceland and their ability to buffer large environmental changes. © 2013 Elsevier B.V.

A cross-national cross-sectional survey of the attitudes and perceived competence of final-year medicine, nursing and pharmacy students in relation to end-of-life care in dementia

Background:Little is known about the attitudes of healthcare professional students' perceived competence and confidence in treating those with dementia who are at the end of life.Aim:To explore the attitudes of final year medical, nursing and pharmacy students towards people with dementia and to evaluate their perceived competence and confidence dealing with biomedical and psychosocial issues within the context of palliative care provision to patients with dementia.Design:Cross-sectional survey using a questionnaire.Setting/participants:Final-year students in each profession from Queen's University Belfast (Northern Ireland) and the University of Iowa (USA) were recruited.Method:Three versions of an online questionnaire (containing the Attitudes to Dementia Questionnaire and a series of questions on end-of-life care in dementia) were distributed.Results:A total of 368 responses were received (response rate 42.3%). All respondents reported positive attitudes towards people with dementia. US nursing students reported significantly more positive attitudes than the medical students of United States and Northern Ireland. Medical students were more likely to report low confidence in discussing non-medical aspects of dying, whereas nursing students were most likely to feel prepared and confident to do this. Medical and nursing students reported low confidence with aspects of medication-related care; however, data from the pharmacy samples of Northern Ireland and United States suggested that these students felt confident in advising other healthcare professionals on medication-related issues.Conclusions:While healthcare students hold positive attitudes towards people with dementia, some clinical tasks remain challenging and further basic training may be of benefit.

Oncofetal gene SALL4 in aggressive hepatocellular carcinoma

Hepatocellular carcinoma is the third leading cause of cancer-related deaths worldwide. In the heterogeneous group of hepatocellular carcinomas, those with characteristics of embryonic stem-cell and progenitor-cell gene expression are associated with the worst prognosis. The oncofetal gene SALL4, a marker of a subtype of hepatocellular carcinoma with progenitor-like features, is associated with a poor prognosis and is a potential target for treatment.

Invisible Targets, Strengthened Morale: Static Camouflage as a ‘Weapon of the Weak’

In the natural world, camouflage is habitually deployed by 'vulnerable' creatures to deceive predators. Such protective strategies have been culturally, socially and technologically translated into human societies, whereby camouflage has been used to mask intentions, actions, feelings and valuable objects or spaces. Through the material presence of such techniques, everyday spaces can become inscribed as places of sanctuary. Focusing on British civil camouflage work of the 1930s and 1940s, this paper explores the historical, cultural and political connotations of camouflage and how the attainment of invisibility, as a 'weapon of the weak', can both physically and affectively protect urban populations. © 2012 Copyright Taylor and Francis Group, LLC.

Determining the response of African biota to climate change: using the past to model the future

Prediction of biotic responses to future climate change in tropical Africa tends to be based on two modelling approaches: bioclimatic species envelope models and dynamic vegetation models. Another complementary but underused approach is to examine biotic responses to similar climatic changes in the past as evidenced in fossil and historical records. This paper reviews these records and highlights the information that they provide in terms of understanding the local- and regional-scale responses of African vegetation to future climate change. A key point that emerges is that a move to warmer and wetter conditions in the past resulted in a large increase in biomass and a range distribution of woody plants up to 400–500 km north of its present location, the so-called greening of the Sahara. By contrast, a transition to warmer and drier conditions resulted in a reduction in woody vegetation in many regions and an increase in grass/savanna-dominated landscapes. The rapid rate of climate warming coming into the current interglacial resulted in a dramatic increase in community turnover, but there is little evidence for widespread extinctions. However, huge variation in biotic response in both space and time is apparent with, in some cases, totally different responses to the same climatic driver. This highlights the importance of local features such as soils, topography and also internal biotic factors in determining responses and resilience of the African biota to climate change, information that is difficult to obtain from modelling but is abundant in palaeoecological records.

An ultrastructural study of carcinoid tumor of the iris

An iris tumor developed in a 37-year-old woman who had had a bronchial carcinoid tumor resected nine years previously. The iris tumor was locally excised with a modified trabeculectomy approach. Histologic studies showed it to be a metastatic carcinoid tumor. Electron microscopy demonstrated typical dark and pale carcinoid cells with neurosecretory granules, basal bodies, and apical microvilli. The cisternae of the granular endoplasmic reticulum were disposed in a series of concentric rings encapsulating a central core of mitochondria. This unusual type of subcellular organization and specialization is probably a reflection of the slow-growing and highly differentiated nature of the iris tumor.

Using evidence in policy: The importance of mediating beliefs and practices

This article argues that to understand the use of evidence in policy, we need to examine how meanings and practices in the civil service shape what is accepted as knowledge, and how differences between the beliefs and values of the academy and the polity can impede the flow and transfer of knowledge. It considers the importance of social context and shared meanings in legitimating knowledge. Who counts as legitimate knowledge providers has expanded and here the role of stakeholder groups and experiential knowledge is of particular interest. How hierarchy, anonymity, and generalist knowledge within the civil service mediate the use of evidence in policy is examined. The difference in values and ideology of the civil service and the academy has implications for how academic research is interpreted and used to formulate policy and for its position in knowledge power struggles. There are particular issues about the social science nature of evidence to inform rural policy being mediated in a government department more used to dealing with natural science knowledge.

Reparative Complementarity: Ensuring an Effective Remedy for Victims in the Reparation Regime of the International Criminal Court

This article examines the reparation regime of the International Criminal Court in light of its first reparation decision. Based on the reparation jurisprudence established in international law and human rights law to provide victims of international crimes an effective remedy, this article suggests that in order for the International Criminal Court to achieve this objective it needs to go beyond individual criminal responsibility due to its limitations. This article considers the role of reparative complementarity in ensuring an effective remedy to victims of international crimes as part of the reparation regime of the International Criminal Court.
