Profiling the mouse brain endothelial transcriptome in health and disease models reveals a core blood-brain barrier dysfunction module.

Blood vessels in the CNS form a specialized and critical structure, the blood-brain barrier (BBB). We present a resource to understand the molecular mechanisms that regulate BBB function in health and dysfunction during disease. Using endothelial cell enrichment and RNA sequencing, we analyzed the gene expression of endothelial cells in mice, comparing brain endothelial cells with peripheral endothelial cells. We also assessed the regulation of CNS endothelial gene expression in models of stroke, multiple sclerosis, traumatic brain injury and seizure, each having profound BBB disruption. We found that although each is caused by a distinct trigger, they exhibit strikingly similar endothelial gene expression changes during BBB disruption, comprising a core BBB dysfunction module that shifts the CNS endothelial cells into a peripheral endothelial cell-like state. The identification of a common pathway for BBB dysfunction suggests that targeting therapeutic agents to limit it may be effective across multiple neurological disorders

Balancing multiple roles through consensus: Making revisions in haircutting sessions

This study demonstrates how participants in haircutting sessions merge different roles during one of the most sensitive moments of an encounter: requesting and/or making revisions to a new cut. During the process of arriving at a consensus of whether or not changes need to be made to the new cut, the stylist and the client negotiate not only the quality of the cut, but also their expected roles. Caring about both the bodies and the minds of customers is an important element in measuring the quality of cosmetological services, a consideration which may oblige stylists to immediately agree with and act upon every client request or concern. However, simply yielding to the customer’s opinions can threaten the stylist’s role as a beauty expert, one who possesses their own professional standards. The analysis reveals that the participants frequently transform revision requests/offers into mutual decisions through a combination of verbal and bodily actions. In doing so, they harmonize the sometimes conflicting responsibilities of “service provider/patron” and “expert/novice.

A qualitative study comparing commercial and health service weight loss groups, classes and clubs

Background: Group-based interventions for weight loss are popular, however, little is known about how health service groups compare with the commercial sector, from either the participant or the group leader perspective. Currently health professionals have little guidance on how to deliver effective group interventions. The aim of this study was to compare and contrast leaders' and attendees' experiences of health service and commercial weight loss groups, through in-depth interviews and group observations. Methods: Purposive sampling, guided by a sampling frame, was employed to identify diverse groups operating in Scotland with differing content, structures and style. Data collection and analysis took place concurrently in accordance with a grounded theory approach. Thirteen semi-structured group observations and in-depth audio-recorded interviews with 11 leaders and 22 attendees were conducted. Identification of themes and the construction of matrices to identify data patterns were guided by the Framework Method for qualitative analysis. Results: Compared with commercial groups, health service "groups" or "classes" tended to offer smaller periodic fixed term groups, involving gatekeeper referral systems. Commercial organisations provide a fixed branded package, for "club" or "class" members and most commercial leaders share personal experiences of losing weight. Health service leaders had less opportunity for supervision, peer support or specific training in how to run their groups compared with commercial leaders Conclusions: Commercial and health service groups differ in access; attendee and leader autonomy; engagement in group processes; and approaches to leadership and training, which could influence weight loss outcomes. Health service groups can provide different group content and experiences particularly for those with chronic diseases and for populations less likely to attend commercial groups, like men

Inviting pain? Pain, dualism and embodiment in narratives of self-injury

The role of pain in the practice of self-injury is not straightforward. Existing accounts suggest that self-injury does not cause 'physical' pain, however self-injury is also said to alleviate 'emotional' pain by inflicting 'physical' pain. This article explores these tensions using sociological theories regarding the socio-cultural and subjective nature of pain. Analysis derives from in-depth, life-story interviews carried out in the UK with people who had self-injured. Findings contribute to on-going debates within social science regarding the nature of pain. Participants' narratives about pain and self-injury both drew on and challenged dualistic models of embodiment. I suggest that self-injury offers a unique case on which to extend existing theoretical work, which has tended to focus on pain as an unwanted and uninvited entity. In contrast, accounts of self-injury can feature pain as a central aspect of the practice, voluntarily invited into lived experience. © 2013 The Authors.

Arctic passages: liminality, Iñupiat Eskimo mothers and NW Alaska communities in transition

Background. While the primary goal of the NW Alaska Native maternal transport is safe deliveries for mothers from remote villages, little has been done to question the impact of transport on the mothers and communities involved. This study explores how presence of Iñupiat values influences the desire of indigenous women of differing eras and NW Alaska villages to participate in biomedical birth, largely made available by a tribal health-sponsored transport system. Objective. This paper portrays how important it is (and why) for Alaska Native families and women of different generations from various areas of Iñupiat villages of NW Alaska to get to the hospital to give birth. This research asks: How does a community’s presence of Iñupiat values influence women of different eras and locations to participate in a more biomedical mode of birth? Design. Theoretical frameworks of medical anthropology and maternal identity work are used to track the differences in regard to the maternal transport operation for Iñupiat mothers of the area. Presence of Iñupiat values in each of the communities is compared by birth era and location for each village. Content analysis is conducted to determine common themes in an inductive, recursive fashion. Results. A connection is shown between a community’s manifestation of Iñupiat cultural expression and mothers’ acceptance of maternal transport in this study. For this group of Iñupiat Eskimo mothers, there is interplay between community expression of Iñupiat values and desire and lengths gone to by women of different eras and locations. Conclusions. The more openly manifested the Iñupiat values of the community, the more likely alternative birthing practices sought, lessening the reliance on the existing transport policy. Conversely, the more openly western values are manifested in the village of origin, the less likely alternative measures are sought. For this study group, mothers from study villages with openly manifested western values are more likely to easily acquiesce to policy, and “make the best” of their prenatal travel

Beyond price: individuals' accounts of deciding to pay for private healthcare treatment in the UK

<p>Abstract</p> <p>Background</p> <p>Delivering appropriate and affordable healthcare is a concern across the globe. As countries grapple with the issue of delivering healthcare with finite resources and populations continue to age, more health-related care services or treatments may become an optional 'extra' to be purchased privately. It is timely to consider how, and to what extent, the individual can act as both a 'patient' and a 'consumer'. In the UK the majority of healthcare treatments are free at the point of delivery. However, increasingly some healthcare treatments are being made available via the private healthcare market. Drawing from insights from healthcare policy and social sciences, this paper uses the exemplar of private dental implant treatment provision in the UK to examine what factors people considered when deciding whether or not to pay for a costly healthcare treatment for a non-fatal condition.</p> <p>Methods</p> <p>Qualitative interviews with people (n = 27) who considered paying for dental implants treatments in the UK. Data collection and analysis processes followed the principles of the constant comparative methods, and thematic analysis was facilitated through the use of NVivo qualitative data software.</p> <p>Results</p> <p>Decisions to pay for private healthcare treatments are not simply determined by price. Decisions are mediated by: the perceived 'status' of the healthcare treatment as either functional or aesthetic; how the individual determines and values their 'need' for the treatment; and, the impact the expenditure may have on themselves and others. Choosing a private healthcare provider is sometimes determined simply by personal rapport or extant clinical relationship, or based on the recommendation of others.</p> <p>Conclusions</p> <p>As private healthcare markets expand to provide more 'non-essential' services, patients need to develop new skills and to be supported in their new role as consumers.</p

Cosmetic surgery: regulatory challenges in a global beauty market

The market for cosmetic surgery tourism is growing with an increase in people travelling abroad for cosmetic surgery. While the reasons for seeking cosmetic surgery abroad may vary the most common reason is financial, but does cheaper surgery abroad carry greater risks? We explore the risks of poorly regulated cosmetic surgery to society generally before discussing how harm might be magnified in the context of cosmetic tourism, where the demand for cheaper surgery drives the market and makes surgery accessible for increasing numbers of people. This contributes to the normalisation of surgical enhancement, creating unhealthy cultural pressure to undergo invasive and risky procedures in the name of beauty. In addressing the harms of poorly regulated surgery, a number of organisations purport to provide a register of safe and ethical plastic surgeons, yet this arguably achieves little and in the absence of improved regulation the risks are likely to grow as the global market expands to meet demand. While the evidence suggests that global regulation is needed, the paper concludes that since a global regulatory response is unlikely, more robust domestic regulation may be the best approach. While domestic regulation may increase the drive towards foreign providers it may also have a symbolic effect which will reduce this drive by making people more aware of the dangers of surgery, both to society and individual physical wellbeing.

Time, space and touch at work: Body work and labour process (re)organisation

With ‘efficiency savings’ the watchword for health and social care services, reorganisation and labour rationalisation are the order of the day. This article examines the difficulties involved in (re)organising work which takes bodies as its object, or material of production. It shows that working on bodies (‘body work’) systematically delimits possibilities for labour process rationalisation which, in turn, constrains reorganisation of the health and social care sector. It does this in three main ways. First: rigidity in the ratio of workers to bodies-worked-upon limits the potential to increase capital-labour ratios or cut labour. Secondly: the requirement for co-presence and temporal unpredictability in demand for body work diminish the spatial and temporal malleability of the labour process. Thirdly: the nature of bodies as a material of production – complex, unitary and responsive – makes it difficult to standardise, reorganise or rationalise work. A wide-ranging analysis of body work in health and social care, as well as other sectors, fleshes out these three constraints and shows that attempts to overcome them and reorganise the sector in pursuit of cost savings or ‘efficiency’, generate problems for workers and the patients, whose bodies they work upon
