What research we no longer need in neurodegenerative disease at the end of life : The case of research in dementia

A complete silence. That was what we got back from the European experts who had been energetically discussing research priorities in palliative care in neurodegenerative disease (ND) until a short while ago.1 The chair, an entertaining professor with good manners, must have felt the unease and quickly refocused the group to their task. But, wasn’t this the best question of all day? What research we no longer need? As scientists able to consider different perspectives, shouldn’t we have some idea of what research is, by contrast, no longer necessary? Palliative care research and research with people who have ND and are at the end of their life is, by definition, difficult. Making choices is a sensitive issue, but funds are limited. Therefore, we take a counterpoint to the research agenda recently reported by European Union (EU) Joint Programme – Neurodegenerative Disease Research (JPND),1 and consider whether there are studies we no longer need or are low priority, taking the example of dementiaPeer reviewedFinal Accepted Versio

Evaluations of end of life with dementia by families in Dutch and U.S. nursing homes

BACKGROUND: The End-of-Life in Dementia (EOLD) scales comprise the most specific set of instruments developed for evaluations of patients' end of life by their families. It is not known whether the EOLD scales are useful for cross-national comparisons. METHODS: We used a mortality follow-back design in multi-center studies in the Netherlands (pilot study 2005-2007) and the U.S.A. (1999), and we compared EOLD Satisfaction With Care (SWC; last three months of life), Symptom Management (SM; last three months) and Comfort Assessment in Dying (CAD) scores for 54 Dutch and 76 U.S. nursing home residents. RESULTS: SWC total scores did not differ significantly between the Dutch and U.S. studies (31.9, SD 4.7 versus 30.4, SD 6.1), but three of ten items were rated more favorable for Dutch residents, as were SM total scores (29.1, SD 9.2 versus 20.4, SD 10.6). CAD total scores did not differ (32.0, SD 5.4 versus 30.5, SD 5.9, respectively), but the "well-being" subscale was rated more favorably for Dutch residents. Results were similar after adjustment for demographics and dementia severity. CONCLUSION: The Dutch families rated end of life with dementia in nursing homes as somewhat better than did U.S. families. Although differences were small, the observed patterns were consistent. This suggests validity of the SM and CAD to assess differences in quality of dying and possible sensitivity to differences between countries or time frames. Larger, simultaneous, cross-national studies are needed to confirm usefulness of the scales and to detect areas which need improvement in the respective countrie

Antimicrobial Use in Patients with Dementia: Current Concerns and Future Recommendations

Infections are common in people with dementia, and antibiotic use is widespread, albeit highly variable, across healthcare settings and countries. The few studies conducted to date that consider the appropriateness of antibiotic prescribing specifically for people with dementia focus on people with advanced dementia and suggest that much of the prescribing of antibiotics for these patients may be potentially inappropriate. We suggest that clinicians must consider a number of factors to determine appropriateness of antimicrobial prescribing for people with dementia, including the risks and benefits of assessing and treating infections, the uncertainty regarding the effects of antibiotics on patient comfort, goals of care and treatment preferences, hydration status, dementia severity and patient prognosis. Future research should examine antibiotic prescribing and its appropriateness across the spectrum of common infections, dementia severities, care settings and countries, and should consider how antibiotic therapy should be considered in discussions regarding treatment preferences, goals of care and/or advance care planning between clinicians, patients and families

Predictors of spiritual care provision for patients with dementia at the end of life as perceived by physicians : a prospective study

Background: Spiritual caregiving is part of palliative care and may contribute to well being at the end of life. However, it is a neglected area in the care and treatment of patients with dementia. We aimed to examine predictors of the provision of spiritual end-of-life care in dementia as perceived by physicians coordinating the care. Methods: We used data of the Dutch End of Life in Dementia study (DEOLD; 2007-2011), in which data were collected prospectively in 28 Dutch long-term care facilities. We enrolled newly admitted residents with dementia who died during the course of data collection, their families, and physicians. The outcome of Generalized Estimating Equations (GEE) regression analyses was whether spiritual care was provided shortly before death as perceived by the on-staff elderly care physician who was responsible for end-of-life care (last sacraments or rites or other spiritual care provided by a spiritual counselor or staff). Potential predictors were indicators of high-quality, person-centered, and palliative care, demographics, and some other factors supported by the literature. Resident-level potential predictors such as satisfaction with the physician's communication were measured 8 weeks after admission (baseline, by families and physicians), physician-level factors such as the physician's religious background midway through the study, and facility-level factors such as a palliative care unit applied throughout data collection. Results: According to the physicians, spiritual end-of-life care was provided shortly before death to 20.8% (43/207) of the residents. Independent predictors of spiritual end-of-life care were: families' satisfaction with physicians' communication at baseline (OR 1.6, CI 1.0; 2.5 per point on 0-3 scale), and faith or spirituality very important to resident whether (OR 19, CI 5.6; 63) or not (OR 15, CI 5.1; 47) of importance to the physician. Further, female family caregiving was an independent predictor (OR 2.7, CI 1.1; 6.6). Conclusions: Palliative care indicators were not predictive of spiritual end-of-life care; palliative care in dementia may need better defining and implementation in practice. Physician-family communication upon admission may be important to optimize spiritual caregiving at the end of life

Contrast-enhanced micro-CT imaging in murine carotid arteries : a new protocol for computing wall shear stress

Background: Wall shear stress (WSS) is involved in the pathophysiology of atherosclerosis. The correlation between WSS and atherosclerosis can be investigated over time using a WSS-manipulated atherosclerotic mouse model. To determine WSS in vivo, detailed 3D geometry of the vessel network is required. However, a protocol to reconstruct 3D murine vasculature using this animal model is lacking. In this project, we evaluated the adequacy of eXIA 160, a small animal contrast agent, for assessing murine vascular network on micro-CT. Also, a protocol was established for vessel geometry segmentation and WSS analysis. Methods: A tapering cast was placed around the right common carotid artery (RCCA) of ApoE(-/-) mice (n = 8). Contrast-enhanced micro-CT was performed using eXIA 160. An innovative local threshold-based segmentation procedure was implemented to reconstruct 3D geometry of the RCCA. The reconstructed RCCA was compared to the vessel geometry using a global threshold-based segmentation method. Computational fluid dynamics was applied to compute the velocity field and WSS distribution along the RCCA. Results: eXIA 160-enhanced micro-CT allowed clear visualization and assessment of the RCCA in all eight animals. No adverse biological effects were observed from the use of eXIA 160. Segmentation using local threshold values generated more accurate RCCA geometry than the global threshold-based approach. Mouse-specific velocity data and the RCCA geometry generated 3D WSS maps with high resolution, enabling quantitative analysis of WSS. In all animals, we observed low WSS upstream of the cast. Downstream of the cast, asymmetric WSS patterns were revealed with variation in size and location between animals. Conclusions: eXIA 160 provided good contrast to reconstruct 3D vessel geometry and determine WSS patterns in the RCCA of the atherosclerotic mouse model. We established a novel local threshold-based segmentation protocol for RCCA reconstruction and WSS computation. The observed differences between animals indicate the necessity to use mouse-specific data for WSS analysis. For our future work, our protocol makes it possible to study in vivo WSS longitudinally over a growing plaque

Een handreiking voor familieleden over palliatieve zorg bij dementie: evaluatie door zorgverleners en familieleden.

De familie van verpleeghuisbewoners met dementie is meestal betrokken bij de zorg en bij behandelbeslissingen over de bewoner. Hiertoe dienen familieleden geïnformeerd te zijn over het beloop van dementie en mogelijkheden tot palliatieve zorg. Op basis van een Canadese brochure ontwikkelden wij een handreiking met schriftelijke informatie toegesneden op de Nederlandse situatie. Deze handreiking en mogelijke toepassing werden beoordeeld door specialisten ouderengeneeskunde (n = 30), verzorging/verpleging (n = 38), en familieleden (n = 59) na het overlijden van de bewoner. Alle respondenten gaven aan dat er grote behoefte bestaat aan een dergelijke handreiking. De meeste familieleden (93%) hadden de handreiking eerder willen hebben. De verzorging/verpleging dacht vergeleken met specialisten oudergeneeskunde vaker dat de handreiking nuttig zou zijn voor alle of veel families (p = 0,04). De acceptatie van de handreiking onder de respondenten, gemeten op een schaal met 8 stellingen, was het grootst onder familieleden en het kleinst onder specialisten ouderengeneeskunde. Veel respondenten beoordeelden het nut positief (gemiddeld 7,9 tot 8,3 op een schaal van 0-10; SD 0,9 tot 1,4) en het nut verschilde niet tussen de respondentgroepen (p = 0,29). Alle respondenten zagen een rol voor zorgverleners in het overhandigen van de handreiking. Daarnaast vond de helft van de respondenten (53%; geen significant verschil tussen de groepen) dat de handreiking ook zonder tussenkomst van zorgverleners beschikbaar moet zijn; soms zelfs al vóór opname. Concluderend is er grote behoefte aan schriftelijke uitleg over palliatieve zorg bij dementie. De handreiking wordt geschikt gevonden. Een op punten aangepaste versie kan mogelijk zorgverleners en familie in de praktijk ondersteunen
