Emergence of CTX-M Group 1-ESBL producing Klebsiella pneumonia from a tertiary care centre in Karachi, Pakistan.

http://www.jidc.org/index.php/journal/article/view/20818098/422 Background: Extended-spectrum beta-lactamase (ESBL)-producing Klebsiella pneumoniae have been reported previously from Pakistan but the genotypic characteristics of these enzymes is not known. Hence the aim of the study was first to characterise the genotypic content of these beta-lactamases and secondly to assess the clonal relationship of these isolates. Methodology: We analysed 65 non-duplicate ESBL positive, K. pneumoniae isolates prospectively collected based on phenotype as detected using the two-disc method. Isolates were collected from different sources: blood cultures (46.15%; n = 30); tracheal aspirates (24.6%; n = 16); urine (10.7%; n = 7); wound swabs, pus and tissue (18.4%; n = 12). ESBL production was confirmed by the ESBL E-test method and the presence of the blaCTX-M encoding genes was confirmed by polymerase chain reaction. The clonal relationship of clinical isolates was studied by Pulsed Field Gel Electrophoresis. Results: The results showed that 93.84% (n = 61) isolates of K. pneumoniae were positive for the blaCTX-M-1 group. One isolate showed PCR signals for blaCTX-M-25 group. None of our isolates were positive for CTX-M groups 2, 8 and 9. The majority of blaCTX-M positive isolates were genetically unrelated and no epidemic clones were identified. Conclusion: This study reports the emergence of CTX-M groups 1 and 25 producing isolates of K. pneumoniae with genetic diversity in Karachi, Pakistan.

‘Stakeholders’ views of legal and advice services for people admitted to psychiatric hospital’

This paper describes a study that used a mixed method approach to elicit the views of a range of stakeholders about experiences of compulsory admission to psychiatric hospital, and the use of the Mental Health Review Tribunal (MHRT). The paper begins with an introduction to the background of the study, one that took place in Northern Ireland, a region in the UK with its own mental health legislation and policy. A review of literature is then presented. This highlights some of the disadvantages that service users and carers face when dealing with professionals during and following compulsory admission to hospital. This section concludes with an overview of literature on the MHRT in the UK. A range of methods was used to gather data from the following stakeholders: five service user and carer focus group interviews (n = 44); interviews with four lawyers experienced in Tribunal work; an interview with a legal member of the Tribunal; a survey of solicitors who identified themselves as equipped to carry out Tribunal work; interviews with three managers of organisations that provided patient advocacy services; letters to hospital managers requesting information provided to patients and carers. The findings reveal a number of themes associated with these experiences of compulsory admission to hospital and subsequent use of the Tribunal. Service users and carers generally found it difficult to access relevant information about rights, information provided by hospital managers was uneven and lawyers were often not familiar with processes associated with compulsory admission. There was a range of views about the Tribunal. Most respondents felt that the Tribunal was necessary and mostly satisfactory in the way it carried out its functions, but stakeholders raised a number of issues. Carers in particular felt that they should be more involved in decision-making processes, whereas lawyers tended to be focused on more technical, legal issues. Problems of regrading prior to the Tribunal and in examining medical evidence were highlighted by lawyers. There was an appeal for better information and advice by service users and carers, and recognition of the need for better training and education for lawyers. The paper concludes with a brief discussion about current mental health law in the UK, arguing that, in this context, professionals should more proactively use information and advice that can enable service users and carers to defend their rights.

Stroke presentation and hospital management: comparison of neighbouring healthcare systems with differing health policies.

Background: Acute stroke care is shaped by healthcare policies. Differing policies in similar populations allow for assessment of policy impact on health and healthcare outcomes. Aims: To compare stroke presentation and hospital care in two adjacent healthcare systems with differing healthcare policies. Methods: Interviews and chart review of consecutive acute stroke admissions in Northern Ireland (n=103) and the Republic of Ireland (n=100). Results: Marked regional contrasts were evident for key aspects of hospital care. Northern Ireland performed significantly better on 15 of 16 quality of care (Sentinel Audit) items. Delivery on standards was significantly better in Northern Ireland for early assessment (Northern Ireland 72%; Republic of Ireland 54%, p

TRARESA: a tissue microarray-based hospital system for biomarker validation and discovery

Formalin fixed and paraffin embedded tissue (FFPE) collections in pathology departments are the largest resource for retrospective biomedical research studies. Based on the literature analysis of FFPE related research, as well as our own technical validation, we present the Translational Research Arrays (TRARESA), a tissue microarray centred, hospital based, translational research conceptual framework for both validation and/or discovery of novel biomarkers. TRARESA incorporates the analysis of protein, DNA and RNA in the same samples, correlating with clinical and pathological parameters from each case, and allowing (a) the confirmation of new biomarkers, disease hypotheses and drug targets, and (b) the postulation of novel hypotheses on disease mechanisms and drug targets based on known biomarkers. While presenting TRARESA, we illustrate the use of such a comprehensive approach. The conceptualisation of the role of FFPE-based studies in translational research allows the utilisation of this commodity, and adds to the hypothesis-generating armamentarium of existing high-throughput technologies.
