Consultation and consequences: A view on the services experienced by some young people and six families

Reports the views of some young people and 6 families on services received from social care professionals. Summarises the main themes that emerged and emphasises the issue of professional reliability as articulated in these 2 small, but in depth, studies. The views of both sets of interviewees contributed to the creation of a course for front line managers drawing from user and worker consultations. Draws on the interviews to shed light on various aspects of professional relationships with services users and what they said they wanted. Discussion sets this in the context of policy agenda

‘Not easily put into a box’: constructing professional identity

Researching the interplay between social work students' personal and professional identities, I found that, in talking about becoming professionals, students drew on a wide range of discourses. Three common usages of the term ‘professional identity’ are explored here: it can be thought of in relation to desired traits; it can also be used in a collective sense to convey the ‘identity of the profession’. Taking a more subjective approach, professional identity can be regarded as a process in which each individual comes to have a sense of themselves as a social worker. I argue that the variations in students' talk reflect a wide range of cultural understandings that are prevalent within the social work community and society in general, and conclude that professional identity is more complicated than adopting certain traits or values, or even demonstrating competence. The different meanings of professional identity all have something to offer, providing resources for students as they construct themselves as social workers. This is important for social work education because it acknowledges the dynamic nature of professional identity, highlights the difficult identity work which each student must undertake, and prompts us to consider how this process might best be supported

Disrupting Hypoxia-Induced Bicarbonate Transport Acidifies Tumor Cells and Suppresses Tumor Growth

Tumor hypoxia is associated clinically with therapeutic resistance and poor patient outcomes. One feature of tumor hypoxia is activated expression of carbonic anhydrase IX (CA9), a regulator of pH and tumor growth. In this study, we investigated the hypothesis that impeding the reuptake of bicarbonate produced extracellularly by CA9 could exacerbate the intracellular acidity produced by hypoxic conditions, perhaps compromising cell growth and viability as a result. In 8 of 10 cancer cell lines, we found that hypoxia induced the expression of at least one bicarbonate transporter. The most robust and frequent inductions were of the sodium-driven bicarbonate transporters SLC4A4 and SLC4A9, which rely upon both HIF1α and HIF2α activity for their expression. In cancer cell spheroids, SLC4A4 or SLC4A9 disruption by either genetic or pharmaceutical approaches acidified intracellular pH and reduced cell growth. Furthermore, treatment of spheroids with S0859, a small-molecule inhibitor of sodium-driven bicarbonate transporters, increased apoptosis in the cell lines tested. Finally, RNAi-mediated attenuation of SLC4A9 increased apoptosis in MDA-MB-231 breast cancer spheroids and dramatically reduced growth of MDA-MB-231 breast tumors or U87 gliomas in murine xenografts. Our findings suggest that disrupting pH homeostasis by blocking bicarbonate import might broadly relieve the common resistance of hypoxic tumors to anticancer therapy

Intergroup conflict management strategies from a nobel peace laureate: The case of Jose Ramos-Horta

We report on the case of Dr. José Ramos-Horta (JRH), a 1996 Nobel Peace Laureate, former President of East Timor, and current envoy of the United Nations to Guinea-Bissau. JRH agreed to an interview detailing the peace building strategies he has used to manage conflicts. The transcript of his Nobel Laureate acceptance speech was also analysed to strengthen the overall narrative. Our findings suggest two higher-order themes: (1) psycho-social skills, and (2) social networking. Specifically, JRH uses active listening, mindful breaks, and awareness of media trends to create personal and strategic networking contacts, which are critical elements in managing conflict

Piperidinols that show anti-tubercular activity as inhibitors of arylamine N-acetyltransferase: an essential enzyme for mycobacterial survival inside macrophages

Latent M. tuberculosis infection presents one of the major obstacles in the global eradication of tuberculosis (TB). Cholesterol plays a critical role in the persistence of M. tuberculosis within the macrophage during latent infection. Catabolism of cholesterol contributes to the pool of propionyl-CoA, a precursor that is incorporated into cell-wall lipids. Arylamine N-acetyltransferase (NAT) is encoded within a gene cluster that is involved in the cholesterol sterol-ring degradation and is essential for intracellular survival. The ability of the NAT from M. tuberculosis (TBNAT) to utilise propionyl-CoA links it to the cholesterol-catabolism pathway. Deleting the nat gene or inhibiting the NAT enzyme prevents intracellular survival and results in depletion of cell-wall lipids. TBNAT has been investigated as a potential target for TB therapies. From a previous high-throughput screen, 3-benzoyl-4-phenyl-1-methylpiperidinol was identified as a selective inhibitor of prokaryotic NAT that exhibited antimycobacterial activity. The compound resulted in time-dependent irreversible inhibition of the NAT activity when tested against NAT from M. marinum (MMNAT). To further evaluate the antimycobacterial activity and the NAT inhibition of this compound, four piperidinol analogues were tested. All five compounds exert potent antimycobacterial activity against M. tuberculosis with MIC values of 2.3-16.9 µM. Treatment of the MMNAT enzyme with this set of inhibitors resulted in an irreversible time-dependent inhibition of NAT activity. Here we investigate the mechanism of NAT inhibition by studying protein-ligand interactions using mass spectrometry in combination with enzyme analysis and structure determination. We propose a covalent mechanism of NAT inhibition that involves the formation of a reactive intermediate and selective cysteine residue modification. These piperidinols present a unique class of antimycobacterial compounds that have a novel mode of action different from known anti-tubercular drugs

Differential modes of DNA binding by mismatch uracil DNA glycosylase from Escherichia coli: implications for abasic lesion processing and enzyme communication in the base excision repair pathway

Mismatch uracil DNA glycosylase (Mug) from Escherichia coli is an initiating enzyme in the base-excision repair pathway. As with other DNA glycosylases, the abasic product is potentially more harmful than the initial lesion. Since Mug is known to bind its product tightly, inhibiting enzyme turnover, understanding how Mug binds DNA is of significance when considering how Mug interacts with downstream enzymes in the base-excision repair pathway. We have demonstrated differential binding modes of Mug between its substrate and abasic DNA product using both band shift and fluorescence anisotropy assays. Mug binds its product cooperatively, and a stoichiometric analysis of DNA binding, catalytic activity and salt-dependence indicates that dimer formation is of functional significance in both catalytic activity and product binding. This is the first report of cooperativity in the uracil DNA glycosylase superfamily of enzymes, and forms the basis of product inhibition in Mug. It therefore provides a new perspective on abasic site protection and the findings are discussed in the context of downstream lesion processing and enzyme communication in the base excision repair pathway

“Experts by Experience”: The Involvement of Service Users and Families in Designing and Implementing Innovations in Family Justice

Drawing on international research, policy and practice this paper explores what is meant by service user involvement, how it has developed and how it has been implemented across different areas of practice. Using examples from across the health and social care fields, it reflects on how the learning from other areas of practice where service user involvement has been successful may be applied to the family justice field. The arguments presented highlight the value of taking a bottom-up approach in designing and implementing innovations in family justice, which would embrace the views of family members including children, as “service users”. It is important, however, to balance both the challenges and the opportunities offered by involving those who are ‘experts by experience’ in the Family Justice processes, in order to lead to improved services and experiences

The ongoing impacts of hepatitis C - a systematic narrative review of the literature

Extent: 13p.BackgroundMany countries have developed, or are developing, national strategies aimed at reducing the harms associated with hepatitis C infection. Making these strategies relevant to the vast majority of those affected by hepatitis C requires a more complete understanding of the short and longer term impacts of infection. We used a systematic approach to scope the literature to determine what is currently known about the health and psychosocial impacts of hepatitis C along the trajectory from exposure to ongoing chronic infection, and to identify what knowledge gaps remain.MethodsPubMed, Current Contents and PsychINFO databases were searched for primary studies published in the ten years from 2000-2009 inclusive. Two searches were conducted for studies on hepatitis C in adult persons focusing on: outcomes over time (primarily cohort and other prospective designs); and the personal and psychosocial impacts of chronic infection. All retrieved studies were assessed for eligibility according to specific inclusion/exclusion criteria, data completeness and methodological coherence. Outcomes reported in 264 included studies were summarized, tabulated and synthesized.ResultsInjecting drug use (IDU) was a major risk for transmission with seroconversion occurring relatively early in injecting careers. Persistent hepatitis C viraemia, increasing age and excessive alcohol consumption independently predicted disease progression. While interferon based therapies reduced quality of life during treatment, improvements on baseline quality of life was achieved post treatment--particularly when sustained viral response was achieved. Much of the negative social impact of chronic infection was due to the association of infection with IDU and inflated assessments of transmission risks. Perceived discrimination was commonly reported in health care settings, potentially impeding health care access. Perceptions of stigma and experiences of discrimination also had direct negative impacts on wellbeing and social functioning.ConclusionsHepatitis C and its management continue to have profound and ongoing impacts on health and social well being. Biomedical studies provided prospective information on clinical aspects of infection, while the broader social and psychological studies presented comprehensive information on seminal experiences (such as diagnosis and disclosure). Increasing the focus on combined methodological approaches could enhance understanding about the health and social impacts of hepatitis C along the life course.Emma R Miller, Stephen McNally, Jack Wallace, Marisa Schlichthors
