Traumatic Floating Clavicle: A Case Report

Shoulder girdle injuries after high energy traumatic impacts to the shoulder have been well documented. Based on the series of 1603 injuries of the shoulder girdle reported by Cave and colleagues, 85% of the dislocations were glenohumeral, 12% acromioclavicular and 3% sternoclavicular. Less frequently described are injuries involving both the sternoclavicular and acromioclavicular joints simultaneously in one extremity. The present case report discusses a case of traumatic floating clavicle associated with ipsilateral forearm and wrist injury which was treated surgically

Microbial fuel cells: a green and alternative source for bioenergy production

Microbial fuel cell (MFC) represents one of the green technologies for the production of bioenergy. MFCs using microalgae produce bioenergy by converting solar energy into electrical energy as a function of metabolic and anabolic pathways of the cells. In the MFCs with bacteria, bioenergy is generated as a result of the organic substrate oxidation. MFCs have received high attention from researchers in the last years due to the simplicity of the process, the absence in toxic by-products, and low requirements for the algae growth. Many studies have been conducted on MFC and investigated the factors affecting the MFC performance. In the current chapter, the performance of MFC in producing bioenergy as well as the factors which influence the efficacy of MFCs is discussed. It appears that the main factors affecting MFC’s performance include bacterial and algae species, pH, temperature, salinity, substrate, mechanism of electron transfer in an anodic chamber, electrodes materials, surface area, and electron acceptor in a cathodic chamber. These factors are becoming more influential and might lead to overproduction of bioenergy when they are optimized using response surface methodology (RSM)

Development of Trust in an Online Breast Cancer Forum: A Qualitative Study

Background: Online health forums provide peer support for a range of medical conditions, including life-threatening and terminal illnesses. Trust is an important component of peer-to-peer support, although relatively little is known about how trust forms within online health forums. Objective: The aim of this paper is to examine how trust develops and influences sharing among users of an online breast cancer forum. Methods: An interpretive qualitative approach was adopted. Data were collected from forum posts from 135 threads on nine boards on the UK charity, Breast Cancer Care (BCC). Semi-structured interviews were conducted with 14 BCC forum users. Both datasets were analysed thematically using Braun and Clarke’s [2006] approach and combined to triangulate analysis. Results: Trust operates in three dimensions, structural, relational and temporal, which intersect with each other and do not operate in isolation. The structural dimension relates to how the affordances and formal rules of the site affected trust. The relational dimension refers to how trust was necessarily experienced in interactions with other forum users: it emerged within relationships and was a social phenomenon. The temporal dimension relates to how trust changed over time and was influenced by the length of time users spent on the forum. Conclusions: Trust is a process that changes over time, and which is influenced by structural features of the forum and informal but collectively understood relational interactions among forum users. The study provides a better understanding of how the intersecting structural, relational and temporal aspects that support the development of trust facilitate sharing in online environments. These findings will help organisations developing online health forums

Examining intersectional inequalities in access to health (enabling) resources in disadvantaged communities in Scotland: advancing the participatory paradigm.

BACKGROUND: Multiple structural, contextual and individual factors determine social disadvantage and affect health experience. There is limited understanding, however, of how this complex system works to shape access to health enabling resources (HER), especially for most marginalised or hard-to-reach populations. As a result, planning continues to be bereft of voices and lived realities of those in the margins. This paper reports on key findings and experience of a participatory action research (PAR) that aimed to deepen understanding of how multiple disadvantages (and structures of oppression) interact to produce difference in access to resources affecting well-being in disadvantaged communities in Edinburgh. METHODS: An innovative approach combining intersectionality and PAR was adopted and operationalised in three overlapping phases. A preparatory phase helped establish relationships with participant groups and policy stakeholders, and challenge assumptions underlying the study design. Field-work and analysis was conducted iteratively in two phases: with a range of participants working in policy and community roles (or 'bridge' populations), followed by residents of one Edinburgh locality with relatively high levels of deprivation (As measured by the Scottish Index of Multiple Deprivation, a geographically-based indicator. See http://www.gov.scot/Topics/Statistics/SIMD/DataAnalysis/SPconstituencyprofile/EdinburghNorthern-Leith ). Traditional qualitative methods (interviews, focus groups) alongside participatory methods (health resource mapping, spider-grams, photovoice) were employed to facilitate action-oriented knowledge production among multiply disadvantaged groups. RESULTS: There was considerable agreement across groups and communities as to what healthful living (in general) means. This entailed a combination of material, environmental, socio-cultural and affective resources including: a sense of belonging and of purpose, feeling valued, self-esteem, safe/secure housing, reliable income, and access to responsive and sensitive health care when needed. Differences emerge in the value placed by people at different social locations on these resources. The conditions/aspects of their living environment that affected their access to and ability to translate these resources into improved health also appeared to vary with social location. CONCLUSION: Integrating intersectionality with PAR enables the generation of a fuller understanding of disparities in the distribution of, and access to, HER, notably from the standpoint of those excluded from mainstream policy and planning processes. Employing an intersectionality lens helped illuminate links between individual subjectivities and wider social structures and power relations. PAR on the other hand offered the potential to engage multiply disadvantaged groups in a process to collectively build local knowledge for action to develop healthier communities and towards positive community-led social change

Simultaneous Inhibition of mTOR-Containing Complex 1 (mTORC1) and MNK Induces Apoptosis of Cutaneous T-Cell Lymphoma (CTCL) Cells

BACKGROUND: mTOR kinase forms the mTORC1 complex by associating with raptor and other proteins and affects a number of key cell functions. mTORC1 activates p70S6kinase 1 (p70S6K1) and inhibits 4E-binding protein 1 (4E-BP1). In turn, p70S6K1 phosphorylates a S6 protein of the 40S ribosomal subunit (S6rp) and 4E-BP1, with the latter negatively regulating eukaryotic initiation factor 4E (eIF-4E). MNK1 and MNK2 kinases phosphorylate and augment activity of eIF4E. Rapamycin and its analogs are highly specific, potent, and relatively non-toxic inhibitors of mTORC1. Although mTORC1 activation is present in many types of malignancies, rapamycin-type inhibitors shows relatively limited clinical efficacy as single agents. Initially usually indolent, CTCL displays a tendency to progress to the aggressive forms with limited response to therapy and poor prognosis. Our previous study (M. Marzec et al. 2008) has demonstrated that CTCL cells display mTORC1 activation and short-term treatment of CTCL-derived cells with rapamycin suppressed their proliferation and had little effect on the cell survival. METHODS: Cells derived from CTCL were treated with mTORC1 inhibitor rapamycin and MNK inhibitor and evaluated for inhibition of the mTORC1 signaling pathway and cell growth and survival. RESULTS: Whereas the treatment with rapamycin persistently inhibited mTORC1 signaling, it suppressed only partially the cell growth. MNK kinase mediated the eIF4E phosphorylation and inhibition or depletion of MNK markedly suppressed proliferation of the CTCL cells when combined with the rapamycin-mediated inhibition of mTORC1. While MNK inhibition alone mildly suppressed the CTCL cell growth, the combined MNK and mTORC1 inhibition totally abrogated the growth. Similarly, MNK inhibitor alone displayed a minimal pro-apoptotic effect; in combination with rapamycin it triggered profound cell apoptosis. CONCLUSIONS: These findings indicate that the combined inhibition of mTORC1 and MNK may prove beneficial in the treatment of CTCL and other malignancies

Moving out of the shadows: accomplishing bisexual motherhood

Our qualitative study explored the ways in which bisexual mothers came to identify as such and how they structured their relationships and parenting within hetero-patriarchal society. The experiences of seven self-identified White bisexual women (aged from 28 to 56-years-old) from across England and the Republic of Ireland were investigated through semi-structured interviews. Participants’ children were aged 8 months to 28 years old at the time of their interviews. A thematic narrative analysis highlighted the following issues that participants had encountered in constructing their self-identity: prioritizing children; connecting and disconnecting with others and finessing self-definition; questioning societal relationship expectations. Nevertheless, participants varied considerably in how each of the themes identified were reflected in their lives, in particular depending upon each participant’s interpretation of her local social context. Both motherhood and self-identifying as bisexual gave a sense of meaning and purpose to participants’ life stories, although participants sometimes foregrounded their commitment to their children even at a personal cost to their bisexual identity. Using three different theoretical perspectives from feminist theory, queer theory and life course theory, the narratives analysed revealed ways in which bisexual motherhood not only had been influenced both intentionally and unintentionally by heteronormative expectations but also had directly and indirectly challenged these expectations
