Day care for people with dementia: A qualitative study comparing experiences from Norway and Scotland

Potential benefits from day care attendance are reported in the literature for both people with dementia and caregivers, although the evidence-base is limited. The study aimed to explore and compare experiences of day care services for people with dementia as described by day care attendees and their caregivers in Norway and Scotland. Whereas day care receives prominence in Norway’s national dementia plan, Scotland does not highlight day care in its national dementia strategy. A qualitative cross-national comparative study was undertaken. Semi-structured interviews were conducted with 17 people with dementia and 17 caregivers in Norway, and 19 people with dementia and 15 caregivers in Scotland. Data were analyzed thematically and comparatively to explore the experiences and outcomes of the participants. Findings indicate positive outcomes from day care for both people with dementia and caregivers. Satisfaction with services related to meaningful activities, getting out of the home, strengthening social connections and careful staff facilitation to create a positive and welcoming atmosphere. There were strong similarities in the content of services and experiences reported in the two countries. Some minor differences were noted, with caregiver support being an area of notable divergence in experiences. Specialist day care for people with dementia seems to provide important support and positive outcomes for people with dementia, and respite and reassurance for their caregivers. More research is needed to further explore the effect of day care designed for people with dementia both on the attendees and their caregivers

Inhibition of mitochondrial respiration prevents BRAF-mutant melanoma brain metastasis

Melanoma patients carry a high risk of developing brain metastases, and improvements in survival are still measured in weeks or months. Durable disease control within the brain is impeded by poor drug penetration across the blood-brain barrier, as well as intrinsic and acquired drug resistance. Augmented mitochondrial respiration is a key resistance mechanism in BRAF-mutant melanomas but, as we show in this study, this dependence on mitochondrial respiration may also be exploited therapeutically. We first used high-throughput pharmacogenomic profiling to identify potentially repurposable compounds against BRAF-mutant melanoma brain metastases. One of the compounds identified was β-sitosterol, a well-tolerated and brain-penetrable phytosterol. Here we show that β-sitosterol attenuates melanoma cell growth in vitro and also inhibits brain metastasis formation in vivo. Functional analyses indicated that the therapeutic potential of β-sitosterol was linked to mitochondrial interference. Mechanistically, β-sitosterol effectively reduced mitochondrial respiratory capacity, mediated by an inhibition of mitochondrial complex I. The net result of this action was increased oxidative stress that led to apoptosis. This effect was only seen in tumor cells, and not in normal cells. Large-scale analyses of human melanoma brain metastases indicated a significant role of mitochondrial complex I compared to brain metastases from other cancers. Finally, we observed completely abrogated BRAF inhibitor resistance when vemurafenib was combined with either β-sitosterol or a functional knockdown of mitochondrial complex I. In conclusion, based on its favorable tolerability, excellent brain bioavailability, and capacity to inhibit mitochondrial respiration, β-sitosterol represents a promising adjuvant to BRAF inhibitor therapy in patients with, or at risk for, melanoma brain metastases.publishedVersio

General practitioners' patient-centredness and responses to patients' emotional cues and concerns: relationships with perceived empathy in areas of high and low socioeconomic deprivation

<b>Background</b> Physician empathy is important to patients across the socio-economic spectrum. However, whether socioeconomic status (SES) influences how patients’ judge physician empathy is not known. We investigated how patients’ perceptions of their general practitioners’ (GPs) empathy related to objectively measured patient-centeredness of the GPs and their detection and response to emotional cues.<p></p> <b>Methods</b> Secondary analysis of 112 videoed consultations of 8 GPs with the high and low empathy scores as rated by patients using the Consultation and Relational Empathy (CARE) Measure working in high or low deprivation settings in Scotland. Objective assessment involved the Measure of Patient-Centredness (MPCC) which has 3 components (exploring disease and illness experience, understanding the whole person, and finding common ground) and the Verona coding system (which measures emotional cues, concerns and responses).<p></p> <b>Results</b> GPs rated by patients as being empathic were more patient-centred overall than those rated as less empathic, in both high (p = 0.03) and low deprivation areas (p = 0.05). In high deprivation areas, perceived empathy was related to finding common ground (p = 0.02) whereas in low deprivation areas it was related to understanding the whole person (p= 0.01). In high deprivation areas, empathic GPs also had significantly different responses to emotional cues and concerns than GPs perceived as having low empathy.<p></p> <b>Conclusion</b> Socioeconomic status appears to affect how patients judge practitioner empathy. This study emphasises the importance of finding common ground and detecting and responding actively to emotional cues in consultations in high deprivation areas. Further research on a larger sample is warranted

Mitochondrial physiology

As the knowledge base and importance of mitochondrial physiology to evolution, health and disease expands, the necessity for harmonizing the terminology concerning mitochondrial respiratory states and rates has become increasingly apparent. The chemiosmotic theory establishes the mechanism of energy transformation and coupling in oxidative phosphorylation. The unifying concept of the protonmotive force provides the framework for developing a consistent theoretical foundation of mitochondrial physiology and bioenergetics. We follow the latest SI guidelines and those of the International Union of Pure and Applied Chemistry (IUPAC) on terminology in physical chemistry, extended by considerations of open systems and thermodynamics of irreversible processes. The concept-driven constructive terminology incorporates the meaning of each quantity and aligns concepts and symbols with the nomenclature of classical bioenergetics. We endeavour to provide a balanced view of mitochondrial respiratory control and a critical discussion on reporting data of mitochondrial respiration in terms of metabolic flows and fluxes. Uniform standards for evaluation of respiratory states and rates will ultimately contribute to reproducibility between laboratories and thus support the development of data repositories of mitochondrial respiratory function in species, tissues, and cells. Clarity of concept and consistency of nomenclature facilitate effective transdisciplinary communication, education, and ultimately further discovery

local buzz, global pipelines and the process of knowledge creation

The version of record [Bathelt, H., Malmberg, A., & Maskell, P. (2004). Clusters and knowledge: Local buzz, global pipelines and the process of knowledge creation. Progress in Human Geography, 28(1), 31-56.] is available online at: http://phg.sagepub.com/content/28/1/31 [doi: 10.1191/0309132504ph469oa]The paper is concerned with spatial clustering of economic activity and its relation to the spatiality of knowledge creation in interactive learning processes. It questions the view that tacit knowledge transfer is confined to local milieus whereas codified knowledge may roam the globe almost frictionlessly. The paper highlights the conditions under which both tacit and codified knowledge can be exchanged locally and globally. A distinction is made between, on the one hand, the learning processes taking place among actors embedded in a community by just being there dubbed buzz and, on the other, the knowledge attained by investing in building channels of communication called pipelines to selected providers located outside the local milieu. It is argued that the co-existence of high levels of buzz and many pipelines may provide firms located in outward-looking and lively clusters with a string of particular advantages not available to outsiders. Finally, some policy implications, stemming from this argument, are identified
