Repeated context-specific actions disrupt feedforward adjustments in motor commands in younger and older adults.

The flexibility of the motor system to adjust a planned action before or during the execution of the movement in response to sensory information is critical for preventing errors in motor control. As individuals age, this function declines, leading to an increased incidence of motor errors. Although sensory processing and cognitive decline are known contributors to this impairment, here, we test the hypothesis that repetition of context-specific planned actions interferes with the adjustment of feedforward motor commands. Younger and older participants were instructed to grasp and lift a T-shaped object with a concealed, off-sided center of mass and minimize its roll through anticipatory force control, relying predominantly on predictive model-driven planning (i.e., sensorimotor memories) developed through repeated lifts. We selectively manipulate the number of trial repeats with the center of mass on one side before switching it to the other side of the T-shaped object. The results showed that increasing the number of repetitions improved performance in manipulating an object with a given center of mass but led to increased errors when the object's center of mass was switched. This deleterious effect of repetition on feedforward motor adjustment was observed in younger and older adults. Critically, we show these effects on an internal model-driven motor planning task that relies predominantly on sensorimotor memory, with no differences in sensory inputs from the repetition manipulation. The findings indicate that feedforward motor adjustments are hampered by repetitive stereotyped planning and execution of motor behavior.NEW & NOTEWORTHY Adjusting planned actions in response to sensory stimuli degrades with age contributing to increased incidence of errors ranging from clumsy spills to catastrophic falls. Multiple factors likely contribute to age-related motor inflexibility, including sensory- and cognition-supporting system declines. Here, we present compelling evidence for repetition to disrupt feedforward adjusting of motor commands in younger and older adults, which suggests increases in stereotypy as a deleterious potentiator of motor control errors.

Complex advance care planning intervention in general practice (ACP-GP): a cluster-randomised controlled trial.

BACKGROUND: Advance care planning (ACP) is an iterative communication process about patients' preferences for future care. In general practice, there are barriers to ACP at patient, GP, and healthcare-system levels. A complex intervention may be necessary to reduce barriers. AIM: To evaluate the effects of a complex ACP intervention for patients with chronic, life-limiting illness in general practice (ACP-GP). DESIGN AND SETTING: A cluster-randomised controlled trial was undertaken in Belgian general practice. METHOD: ACP-GP included a patient workbook, GP training, ACP conversations, and a documentation template. The control group received usual care. Outcomes were the 15-item ACP Engagement Survey for patients and the ACP Self-Efficacy scale for GPs. Linear mixed models evaluated differences at 3 months (T1, effectiveness evaluation) and 6 months (T2) post-baseline. Analysis was intention-to-treat. RESULTS: In total, 35 GPs and 95 patients were randomised. Patient ACP engagement did not differ between the intervention and control group at T1 (baseline-adjusted mean difference = 0.34; 95% confidence interval [CI] = -0.02 to 0.69; P = 0.062) or T2 (baseline-adjusted mean difference = 0.20; 95% CI = -0.17 to 0.57; P = 0.28). For GP ACP self-efficacy, there were no significant differences between groups at T1 (baseline-adjusted mean difference = 0.16; 95% CI = -0.04 to 0.35; P = 0.11) or at T2 (baseline-adjusted mean difference = 0.11; 95% CI = -0.09 to 0.31; P = 0.27). CONCLUSION: ACP-GP did not improve patient engagement and GP self-efficacy more than usual care. Both groups showed patterns of increase from baseline. Trial procedures and the COVID-19 pandemic may have increased awareness about ACP.

Do cancer centres and palliative care wards routinely measure patients' quality of life? An international cross-sectional survey study.

PURPOSE: Routinely assessing quality of life (QoL) of patients with cancer is crucial for improving patient-centred cancer care. However, little is known about whether or how cancer centres assess QoL for clinical practice or for research purposes. Therefore, our study aimed to investigate if QoL data is collected and if so, how and for what purposes. METHOD: We conducted a cross-sectional survey study among 32 cancer centres in Europe and Canada. Centre representatives identified persons who they judged to have sufficient insight into QoL data collections in their wards to complete the survey. Descriptive statistics were used to summarise the information on QoL assessment and documentation. RESULTS: There were 20 (62.5%) responding cancer centres. In total, 30 questionnaires were completed, of which 13 were completed for cancer wards and 17 for palliative care wards. We found that 23.1% and 38.5% of the cancer wards routinely assessed QoL among inpatients and outpatients with cancer, respectively, whereas, in palliative care wards, 52.9% assessed QoL for outpatients with cancer and 70.6% for the inpatients. Wide variabilities were observed between the cancer centres in how, how often, when and which instruments they used to assess QoL. CONCLUSION: A sizable proportion of the cancer wards, especially, and palliative care wards apparently does not routinely assess patients' QoL, and we found wide variabilities between the cancer centres in how they do it. To promote routine assessment of patients' QoL, we proposed several actions, such as addressing barriers to implementing patient-reported outcome measures through innovative e-health platforms.

Advance care planning engagement in patients with chronic, life-limiting illness: baseline findings from a cluster-randomised controlled trial in primary care.

BACKGROUND: Advance care planning (ACP) has been characterised as a complex process of communication and decision making. For ACP behaviour change, underlying processes such as self-efficacy and readiness are needed. However, studies about which patient characteristics are associated with ACP have mainly focused on whether ACP actions are completed, leaving behaviour change processes unexplored. AIM: To assess whether patients' characteristics and patient-perceived quality of GP ACP communication were associated with patients' ACP engagement. DESIGN AND SETTING: Baseline data were used from the ACP-GP cluster-randomised controlled trial in patients with chronic, life-limiting illness (n = 95). METHOD: Patients completed questionnaires detailing demographic and clinical characteristics, and their perception about their GPs' ACP information provision and listening. Engagement was measured using the 15-item ACP Engagement Survey, with self-efficacy and readiness subscales. Linear mixed models tested associations with engagement. RESULTS: Demographic and clinical characteristics were not associated with engagement; nor was how much ACP information patients received from their GP or the extent to which the GP listened to what was important for the patient to live well or important to the patient regarding future care. Higher overall ACP engagement (P = 0.002) and self-efficacy (P<0.001) were observed in patients who gave a high rating for the extent to which their GP listened to their worries regarding future health. CONCLUSION: This study suggests that GPs providing information about ACP alone is not associated with a patient's ACP engagement; an important element is to listen to patients' worries regarding their future health.

The ethics of pet robots in dementia care settings: Care professionals' and organisational leaders' ethical intuitions.

Background: Pet robots are gaining momentum as a technology-based intervention to support the psychosocial wellbeing of people with dementia. Current research suggests that they can reduce agitation, improve mood and social engagement. The implementation of pet robots in care for persons with dementia raises several ethical debates. However, there is a paucity of empirical evidence to uncover care providers' ethical intuitions, defined as individuals' fundamental moral knowledge that are not underpinned by any specific propositions. Objectives: Explore care professionals' and organisational leaders' ethical intuitions before and when implementing pet robots in nursing homes for routine dementia care. Materials and methods: We undertook a secondary qualitative analysis of data generated from in-depth, semi-structured interviews with 22 care professionals and organisational leaders from eight nursing homes in Ireland. Data were analysed using reflexive thematic analysis. Ethical constructs derived from a comprehensive review of argument-based ethics literature were used to guide the deductive coding of concepts. An inductive approach was used to generate open codes not falling within the pre-existing concepts. Findings: Ethical intuitions for implementing pet robots manifested at three levels: an (1) individual-relational, (2) organisational and (3) societal level. At the individual-relational level, ethical intuitions involved supporting the autonomy of residents and care providers, using the robots to alleviate residents' social isolation, and the physical and psychosocial impacts associated with their use. Some care providers had differing sentiments about anthropomorphizing pet robots. At the organisational level, intuitions related to the use of pet robots to relieve care provision, changes to the organisational workflow, and varying extents of openness amongst care providers to use technological innovations. At the societal level, intuitions pertained conceptions of dementia care in nursing homes, and social justice relating to the affordability and availability of pet robots. Discrepancies between participants' ethical intuitions and existing philosophical arguments were uncovered. Conclusion: Care professionals and organisational leaders had different opinions on how pet robots are or should be implemented for residents with dementia. Future research should consider involving care practitioners, people with dementia, and their family members in the ethics dialogue to support the sustainable, ethical use of pet robots in practice.

Advance care planning in amyotrophic lateral sclerosis (ALS): study protocol for a qualitative longitudinal study with persons with ALS and their family carers.

INTRODUCTION: Amyotrophic lateral sclerosis (ALS) is an incurable motor neuron degenerative disease that has rapid progression and is associated with cognitive impairment. For people with ALS (pALS) and their family carers, advance care planning (ACP) is beneficial, as it can lead to feelings of control/relief and refusal of unwanted treatments. However, evidence concerning the experiences and preferences regarding ACP of pALS and their family carers, especially when their symptoms progress, is scarce. This article describes the protocol for a qualitative longitudinal study that aims to explore: (1) the experiences with ACP and the preferences for future care and treatment of pALS and their family carers and (2) how these experiences and preferences change over time. METHODS AND ANALYSIS: A qualitative, longitudinal, multiperspective design. A total of eight to nine dyads (pALS and their family carers) will be recruited, and semistructured interviews administered every 3 months over a 9-month period. Qualitative longitudinal analysis involves content analysis via in-depth reading, followed by a two-step timeline method to describe changes in experiences and preferences within and across participants. ETHICS AND DISSEMINATION: This protocol has been approved by the central ethical committee of the University Hospital of Brussels, and local ethical committees of the other participating hospitals (B.U.N. B1432020000128). The results will be disseminated via the research group's (endoflifecare.be) website, social media and newsletter and via presentations at national and international scientific conferences.

Impact of home healthcare on end-of-life outcomes for people with dementia: a systematic review.

BACKGROUND: Home healthcare (HHC) comprises clinical services provided by medical professionals for people living at home with various levels of care needs and health conditions. HHC may reduce care transitions from home to acute hospitals, but its long-term impact on homebound people living with dementia (PLWD) towards end-of-life remains unclear. We aim to describe the impact of HHC on acute healthcare utilization and end-of-life outcomes in PLWD. METHODS: Design: Systematic review of quantitative and qualitative original studies which examine the association between HHC and targeted outcomes. INTERVENTIONS: HHC. PARTICIPANTS: At least 80% of study participants had dementia and lived at home. MEASUREMENTS: Primary outcome was acute healthcare utilization in the last year of life. Secondary outcomes included hospice palliative care, advance care planning, continuity of care, and place of death. We briefly reviewed selected national policy to provide contextual information regarding these outcomes. RESULTS: From 6831 articles initially identified, we included five studies comprising data on 4493 participants from USA, Japan, and Italy. No included studies received a "high" quality rating. We synthesised core properties related to HHC at three implementational levels. Micro-level: HHC may be associated with a lower risk of acute healthcare utilization in the early period (e.g., last 90 days before death) and a higher risk in the late period (e.g. last 15 days) of the disease trajectory toward end-of-life in PLWD. HHC may increase palliative care referrals. Advance care planning was an important factor influencing end-of-life outcomes. Meso-level: challenges for HHC providers in medical decision-making and initiating palliative care for PLWD at the end-of-life may require further training and external support. Coordination between HHC and social care is highlighted but not well examined. Macro-level: reforms of national policy or financial schemes are found in some countries but the effects are not clearly understood. CONCLUSIONS: This review highlights the dearth of dementia-specific research regarding the impact of HHC on end-of-life outcomes. Effects of advance care planning during HHC, the integration between health and social care, and coordination between primary HHC and specialist geriatric/ palliative care services require further investigation.

Improved quality of care and reduced healthcare costs at the end-of-life among older people with dementia who received palliative home care: A nationwide propensity score-matched decedent cohort study.

BACKGROUND: While palliative home care is advocated for people with dementia, evidence of its effectiveness is lacking. AIM: To evaluate the effects of palliative home care on quality and costs of end-of-life care for older people with dementia. DESIGN: Decedent cohort study using linked nationwide administrative databases and propensity score matching. SETTING/PARTICIPANTS: All home-dwelling older people who died with dementia between 2010 and 2015 in Belgium (N = 23,670). EXPOSURE: Receiving palliative home care support for the first time between 360 and 15 days before death. RESULTS: Five thousand six hundred and thirty-seven (23.8%) received palliative home care support in the last 2 years of life, of whom 2918 received it for the first time between 360 and 15 days before death. Two thousand eight hundred and thirty-nine people who received support were matched to 2839 people who received usual care. After matching, those using palliative home care support, in the last 14 days of life, had lower risk of hospital admission (17.5% vs 50.5%; relative risk (RR) = 0.21), undergoing diagnostic testing (17.0% vs 53.6%; RR = 0.20) and receiving inappropriate medications, but were more likely to die at home (75.7% vs 32.6%; RR = 6.45) and to have primary care professional contacts (mean 11.7 vs mean 5.2), compared with those who did not. Further, they had lower mean total costs of care in the last 30 days of life (incremental cost:-€2129). CONCLUSIONS: Palliative home care use by home-dwelling older people with dementia is associated with improved quality and reduced costs of end-of-life care. Access remains low and should be increased.

Higher Prevalence of Dementia but No Change in Total Comfort While Dying among Nursing Home Residents with Dementia between 2010 and 2015: Results from Two Retrospective Epidemiological Studies.

Important policy developments in dementia and palliative care in nursing homes between 2010 and 2015 in Flanders, Belgium might have influenced which people die in nursing homes and how they die. We aimed to examine differences between 2010 and 2015 in the prevalence and characteristics of residents with dementia in nursing homes in Flanders, and their palliative care service use and comfort in the last week of life. We used two retrospective epidemiological studies, including 198 residents in 2010 and 183 in 2015, who died with dementia in representative samples of nursing homes in Flanders. We found a 15%-point increase in dementia prevalence (p-value < 0.01), with a total of 11%-point decrease in severe to very severe cognitive impairment (p = 0.04). Controlling for residents' characteristics, in the last week of life, there was an increase in the use of pain assessment (+20%-point; p < 0.03) but no change in total comfort. The higher prevalence of dementia in nursing homes with no change in residents' total comfort while dying emphasizes an urgent need to better support nursing homes in improving their capacities to provide timely and high-quality palliative care services to more residents dying with dementia.

No difference in effects of 'PACE steps to success' palliative care program for nursing home residents with and without dementia: a pre-planned subgroup analysis of the seven-country PACE trial.

BACKGROUND: 'PACE Steps to Success' is a multicomponent training program aiming to integrate generalist and non-disease-specific palliative care in nursing homes. This program did not improve residents' comfort in the last week of life, but it appeared to improve quality of care and dying in their last month of life. Because this program included only three dementia-specific elements, its effects might differ depending on the presence or stage of dementia. We aimed to investigate whether the program effects differ between residents with advanced, non-advanced, and no dementia. METHODS: Pre-planned subgroup analysis of the PACE cluster-randomized controlled trial in 78 nursing homes in seven European countries. Participants included residents who died in the previous 4 months. The nursing home staff or general practitioner assessed the presence of dementia; severity was determined using two highly-discriminatory staff-reported instruments. Using after-death questionnaires, staff assessed comfort in the last week of life (Comfort Assessment in Dying-End-of-Life in Dementia-scale; primary outcome) and quality of care and dying in the last month of life (Quality of Dying in Long-Term Care scale; secondary outcome). RESULTS: At baseline, we included 177 residents with advanced dementia, 126 with non-advanced dementia and 156 without dementia. Post-intervention, respectively in the control and the intervention group, we included 136 and 104 residents with advanced dementia, 167 and 110 with non-advanced dementia and 157 and 137 without dementia. We found no subgroup differences on comfort in the last week of life, comparing advanced versus without dementia (baseline-adjusted mean sub-group difference 2.1; p-value = 0.177), non-advanced versus without dementia (2.7; p = 0.092), and advanced versus non-advanced dementia (- 0.6; p = 0.698); or on quality of care and dying in the last month of life, comparing advanced and without dementia (- 0.6; p = 0.741), non-advanced and without dementia (- 1.5; p = 0.428), and advanced and non-advanced dementia (0.9; p = 0.632). CONCLUSIONS: The lack of subgroup difference suggests that while the program did not improve comfort in dying residents with or without dementia, it appeared to equally improve quality of care and dying in the last month of life for residents with dementia (regardless of the stage) and those without dementia. A generalist and non-disease-specific palliative care program, such as PACE Steps to Success, is a useful starting point for future palliative care improvement in nursing homes, but to effectively improve residents' comfort, this program needs further development.

Comfort and clinical events at the end of life of nursing home residents with and without dementia: The six-country epidemiological PACE study.

OBJECTIVES: We aimed to investigate the occurrence rates of clinical events and their associations with comfort in dying nursing home residents with and without dementia. METHODS: Epidemiological after-death survey was performed in nationwide representative samples of 322 nursing homes in Belgium, Finland, Italy, the Netherlands, Poland, and England. Nursing staff reported clinical events and assessed comfort. The nursing staff or physician assessed the presence of dementia; severity was determined using two highly discriminatory staff-reported instruments. RESULTS: The sample comprised 401 residents with advanced dementia, 377 with other stages of dementia, and 419 without dementia (N = 1197). Across the three groups, pneumonia occurred in 24 to 27% of residents. Febrile episodes (unrelated to pneumonia) occurred in 39% of residents with advanced dementia, 34% in residents with other stages of dementia and 28% in residents without dementia (P = .03). Intake problems occurred in 74% of residents with advanced dementia, 55% in residents with other stages of dementia, and 48% in residents without dementia (P < .001). Overall, these three clinical events were inversely associated with comfort. Less comfort was observed in all resident groups who had pneumonia (advanced dementia, P = .04; other stages of dementia, P = .04; without dementia, P < .001). Among residents with intake problems, less comfort was observed only in those with other stages of dementia (P < .001) and without dementia (P = .003), while the presence and severity of dementia moderated this association (P = .03). Developing "other clinical events" was not associated with comfort. CONCLUSIONS: Discomfort was observed in dying residents who developed major clinical events, especially pneumonia, which was not specific to advanced dementia. It is crucial to identify and address the clinical events potentially associated with discomfort in dying residents with and without dementia.

Evaluation of a Palliative Care Program for Nursing Homes in 7 Countries: The PACE Cluster-Randomized Clinical Trial.

Importance: High-quality evidence on how to improve palliative care in nursing homes is lacking. Objective: To investigate the effect of the Palliative Care for Older People (PACE) Steps to Success Program on resident and staff outcomes. Design, Setting, and Participants: A cluster-randomized clinical trial (2015-2017) in 78 nursing homes in 7 countries comparing PACE Steps to Success Program (intervention) with usual care (control). Randomization was stratified by country and median number of beds in each country in a 1:1 ratio. Interventions: The PACE Steps to Success Program is a multicomponent intervention to integrate basic nonspecialist palliative care in nursing homes. Using a train-the-trainer approach, an external trainer supports staff in nursing homes to introduce a palliative care approach over the course of 1 year following a 6-steps program. The steps are (1) advance care planning with residents and family, (2) assessment, care planning, and review of needs and problems, (3) coordination of care via monthly multidisciplinary review meetings, (4) delivery of high-quality care focusing on pain and depression, (5) care in the last days of life, and (6) care after death. Main Outcomes and Measures: The primary resident outcome was comfort in the last week of life measured after death by staff using the End-of-Life in Dementia Scale Comfort Assessment While Dying (EOLD-CAD; range, 14-42). The primary staff outcome was knowledge of palliative care reported by staff using the Palliative Care Survey (PCS; range, 0-1). Results: Concerning deceased residents, we collected 551 of 610 questionnaires from staff at baseline and 984 of 1178 postintervention in 37 intervention and 36 control homes. Mean (SD) age at time of death ranged between 85.22 (9.13) and 85.91 (8.57) years, and between 60.6% (160/264) and 70.6% (190/269) of residents were women across the different groups. Residents' comfort in the last week of life did not differ between intervention and control groups (baseline-adjusted mean difference, -0.55; 95% CI, -1.71 to 0.61; P = .35). Concerning staff, we collected 2680 of 3638 questionnaires at baseline and 2437 of 3510 postintervention in 37 intervention and 38 control homes. Mean (SD) age of staff ranged between 42.3 (12.1) and 44.1 (11.7) years, and between 87.2% (1092/1253) and 89% (1224/1375) of staff were women across the different groups. Staff in the intervention group had statistically significantly better knowledge of palliative care than staff in the control group, but the clinical difference was minimal (baseline-adjusted mean difference, 0.04; 95% CI, 0.02-0.05; P < .001). Data analyses began on April 20, 2018. Conclusions and Relevance: Residents' comfort in the last week of life did not improve after introducing the PACE Steps to Success Program. Improvements in staff knowledge of palliative care were clinically not important. Trial Registration: ISRCTN Identifier: ISRCTN14741671.

Palliative care for people with dementia living at home: A systematic review of interventions.

BACKGROUND: The European Association for Palliative Care White Paper defined optimal palliative care in dementia based on evidence and expert consensus. Yet, we know little on how to achieve this for people with dementia living and dying at home. AIMS: To examine evidence on home palliative care interventions in dementia, in terms of their effectiveness on end-of-life care outcomes, factors influencing implementation, the extent to which they address the European Association for Palliative Care palliative care domains and evidence gaps. DESIGN: A systematic review of home palliative care interventions in dementia. DATA SOURCES: The review adhered to the PRISMA guidelines and the protocol was registered with PROSPERO (CRD42018093607). We searched four electronic databases up to April 2018 (PubMed, Scopus, Cochrane library and CINAHL) and conducted lateral searches. RESULTS: We retrieved eight relevant studies, none of which was of high quality. The evidence, albeit of generally weak quality, showed the potential benefits of the interventions in improving end-of-life care outcomes, for example, behavioural disturbances. The interventions most commonly focused on optimal symptom management, continuity of care and psychosocial support. Other European Association for Palliative Care domains identified as important in palliative care for people with dementia, for example, prognostication of dying or avoidance of burdensome interventions were under-reported. No direct evidence on facilitators and barriers to implementation was found. CONCLUSIONS: The review highlights the paucity of high-quality dementia-specific research in this area and recommends key areas for future work, for example, the need for process evaluation to identify facilitators and barriers to implementing interventions.

Quality of primary palliative care for older people with mild and severe dementia: an international mortality follow-back study using quality indicators.

Background: measuring the quality of primary palliative care for older people with dementia in different countries is important to identify areas where improvements can be made. Objective: using quality indicators (QIs), we systematically investigated the overall quality of primary palliative care for older people with dementia in three different countries. Design/setting: a mortality follow-back survey through nation- and region-wide representative Sentinel Networks of General Practitioners (GPs) in Belgium, Italy and Spain. GPs registered all patient deaths in their practice. We applied a set of nine QIs developed through literature review and expert consensus. Subjects: patients aged 65 or older, who died non-suddenly with mild or severe dementia as judged by GPs (n = 874). Results: findings showed significantly different QI scores between Belgium and Italy for regular pain measurement (mild dementia: BE = 44%, IT = 12%, SP = 50% | severe dementia: BE = 41%, IT = 9%, SP = 47%), acceptance of approaching death (mild: BE = 59%, IT = 48%, SP = 33% | severe: BE = 41%, IT = 21%, SP = 20%), patient-GP communication about illness (mild: BE = 42%, IT = 6%, SP = 20%) and involvement of specialised palliative services (mild: BE = 60%, IT = 20%, SP = 77%). The scores in Belgium differed from Italy and Spain for patient-GP communication about medical treatments (mild: BE = 34%, IT = 12%, SP = 4%) and repeated multidisciplinary consultations (mild: BE = 39%, IT = 5%, SP = 8% | severe: BE = 36%, IT = 10%, SP = 8%). The scores for relative-GP communication, patient death outside hospitals and bereavement counselling did not differ between countries. Conclusion: while the countries studied differed considerably in the overall quality of primary palliative care, they have similarities in room for improvement, in particular, pain measurement and prevention of avoidable hospitalisations.

Integrating palliative care in long-term care facilities across Europe (PACE): protocol of a cluster randomized controlled trial of the 'PACE Steps to Success' intervention in seven countries.

BACKGROUND: Several studies have highlighted the need for improvement in palliative care delivered to older people long-term care facilities. However, the available evidence on how to improve palliative care in these settings is weak, especially in Europe. We describe the protocol of the PACE trial aimed to 1) evaluate the effectiveness and cost-effectiveness of the 'PACE Steps to Success' palliative care intervention for older people in long-term care facilities, and 2) assess the implementation process and identify facilitators and barriers for implementation in different countries. METHODS: We will conduct a multi-facility cluster randomised controlled trial in Belgium, Finland, Italy, the Netherlands, Poland, Switzerland and England. In total, 72 facilities will be randomized to receive the 'Pace Steps to Success intervention' or to 'care as usual'. Primary outcome at resident level: quality of dying (CAD-EOLD); and at staff level: staff knowledge of palliative care (Palliative Care Survey). SECONDARY OUTCOMES: resident's quality of end-of-life care, staff self-efficacy, self-perceived educational needs, and opinions on palliative care. Economic outcomes: direct costs and quality-adjusted life years (QALYs). Measurements are performed at baseline and after the intervention. For the resident-level outcomes, facilities report all deaths of residents in and outside the facilities over a previous four-month period and structured questionnaires are sent to (1) the administrator, (2) staff member most involved in care (3) treating general practitioner, and (4) a relative. For the staff-level outcomes, all staff who are working in the facilities are asked to complete a structured questionnaire. A process evaluation will run alongside the effectiveness evaluation in the intervention group using the RE-AIM framework. DISCUSSION: The lack of high quality trials in palliative care has been recognized throughout the field of palliative care research. This cross-national cluster RCT designed to evaluate the impact of the palliative care intervention for long-term care facilities 'PACE Steps to Success' in seven countries, will provide important evidence concerning the effectiveness as well as the preconditions for optimal implementation of palliative care in nursing homes, and this within different health care systems. TRIAL REGISTRATION: The study is registered at www.isrctn.com - ISRCTN14741671 (FP7-HEALTH-2013-INNOVATION-1 603111) Registration date: July 30, 2015.

Lactic acid bacteria and yeasts associated with spontaneous fermentations during the production of sour cassava starch in Brazil.

Sour cassava starch is a traditional fermented food used in the preparation of fried foods and baked goods such as traditional cheese breads in Brazil. Thirty samples of sour cassava starch were collected from two factories in the state of Minas Gerais. The samples were examined for the presence of lactic acid bacteria, yeasts, mesophilic microorganisms, Bacillus cereus and faecal coliforms. Lactic acid bacteria and yeasts isolates were identified by biochemical tests, and the identities were confirmed by molecular methods. Lactobacillus plantarum and Lactobacillus fermentum were the prevalent lactic acid bacteria in product from both factories, at numbers between 6.0 and 9.0 log cfu g(-)(1). Lactobacillus perolans and Lactobacillus brevis were minor fractions of the population. Galactomyces geothricum and Issatchenkia sp. were the prevalent yeasts at numbers of 5.0 log cfu g(-)(1). A species similar to Candida ethanolica was frequently isolated from one factory. Mesophilic bacteria and amylolytic microorganisms were recovered in high numbers at all stages of the fermentation. B. cereus was found at low numbers in product at both factories. The spontaneous fermentations associated with the production of sour cassava starch involve a few species of lactic acid bacteria at high numbers and a variety of yeasts at relatively low numbers.
