  1. NICE recommendations for psychotherapy in depression: Of limited clinical utility.

    2015-01-01

    In 2009/10 NICE partially updated its guidelines on the treatment and management of depression in adults. Due to methodological shortcomings the recommendations for psychotherapy must be treated with caution. Despite recognising the heterogeneous and comorbid nature of depression, and the limitations of depression as a unitary diagnostic category, NICE treats depression as if it were a unitary entity differentiated only by severity. The guidance ignores important aetiological factors such as trauma, loss and maltreatment, personality and interpersonal difficulties. It excludes the largest naturalistic studies on clinical populations treated in the National Health Service on the grounds that they are observational studies conducted in heterogeneous groups with mixed neurotic disorders. It unquestioningly accepts that the "brand" of psychotherapy has construct validity, and ignores psychotherapy process research indicating significant commonalities, and overlap, between treatment modalities and evidence that individual practitioner effects are larger than the differences between treatment modalities. It fails to consider patient differences and preferences, which are known to influence uptake, completion and response. It takes an exclusively short-term perspective on a chronic relapsing disorder. It does not consider the evidence for longer-term treatments. It is of special concern that NICE misrepresents the findings of its own systematic review by implying that CBT and IPT are superior treatments. NICE's systematic review actually found no evidence of superiority between CBT, IPT, psychodynamic psychotherapy, or counselling. Based on the exclusion of much clinically relevant research demonstrating the effectiveness of psychodynamic psychotherapy and counselling many commentators have alleged a bias towards CBT in the guidance. With regard to service delivery NICE proposes the replacement of psychiatric assessment and individualised treatment plans, with an unproven

    Guidelines are ubiquitous but inconsistently used in UK mental health services. Clinical psychologists are often influential in guideline development and implementation, but opinion within the profession is divided. This study utilized grounded theory methodology to examine clinical psychologists' beliefs about and use of NICE guidelines. Eleven clinical psychologists working in the NHS were interviewed. The overall emerging theme was; NICE guidelines are considered to have benefits but to be fraught with dangers. Participants were concerned that guidelines can create an unhelpful illusion of neatness. They managed the tension between the helpful and unhelpful aspects of guidelines by relating to them in a flexible manner. The participants reported drawing on specialist skills such as idiosyncratic formulation and integration. However, due to the pressures and dominant discourses within services they tended to practice in ways that prevent these skills from being recognized. This led to fears that their professional identity was threatened, which impacted upon perceptions of the guidelines. To our knowledge, the theoretical framework presented in this paper is the first that attempts to explain why NICE guidelines are not consistently utilized in UK mental health services. The current need for services to demonstrate 'NICE compliance' may be leading to a perverse incentive for clinical psychologists in particular to do one thing but say another and for specialist skills to be obscured. If borne out by future studies, this represents a threat to continued quality improvement and also to the profession. Copyright © 2016 John Wiley & Sons, Ltd. Guidelines have many benefits, but the current pressure for services to be 'NICE compliant' may be having unintended negative as well as positive effects. Lack of implementation may be partly the result of active choice by clinicians concerned to use the full range of professional skills and to offer flexibility and choice to

    There is international concern that conflicts of interest (COI) may bias clinical guideline development and render it untrustworthy. Guideline COI policies exist with the aim of reducing this bias but it is not known how such policies are interpreted and used by guideline producing organisations. This study sought to determine how conflicts of interest (COIs) are disclosed and managed by a national clinical guideline developer (NICE: the UK National Institute for Health and Care Excellence). Qualitative study using semi-structured telephone interviews with 14 key informants: 8 senior staff of NICE's guideline development centres and 6 chairs of guideline development groups (GDGs). We conducted a thematic analysis. Participants regard the NICE COI policy as comprehensive leading to transparent and independent guidance. The application of the NICE COI policy is, however, not straightforward and clarity could be improved. Disclosure of COI relies on self reporting and guideline developers have to take "on trust" the information they receive, certain types of COI (non-financial) are difficult to categorise and manage and disclosed COI can impact on the ability to recruit clinical experts to GDGs. Participants considered it both disruptive and stressful to exclude members from GDG meetings when required by the COI policy. Nonetheless the impact of this disruption can be minimised with good group chairing skills. We consider that the successful implementation of a COI policy in clinical guideline development requires clear policies and procedures, appropriate training of GDG chairs and an evaluation of how the policy is used in practice.

  5. NICE guidelines, clinical practice and antisocial personality disorder: the ethical implications of ontological uncertainty.

    Science.gov (United States)

    Pickersgill, M D

    2009-11-01

    The British National Institute for Health and Clinical Excellence (NICE) has recently (28 January 2009) released new guidelines for the diagnosis, treatment and prevention of the psychiatric category antisocial personality disorder (ASPD). Evident in these recommendations is a broader ambiguity regarding the ontology of ASPD. Although, perhaps, a mundane feature of much of medicine, in this case, ontological uncertainty has significant ethical implications as a product of the profound consequences for an individual categorised with this disorder. This paper argues that in refraining from emphasising uncertainty, NICE risks reifying a controversial category. This is particularly problematical given that the guidelines recommend the identification of individuals "at risk" of raising antisocial children. Although this paper does not argue that NICE is "wrong" in any of its recommendations, more emphasis should have been placed on discussions of the ethical implications of diagnosis and treatment, especially given the multiple uncertainties associated with ASPD. It is proposed that these important issues be examined in more detail in revisions of existing NICE recommendations, and be included in upcoming guidance. This paper thus raises key questions regarding the place and role of ethics within the current and future remit of NICE.

  7. Does Methodological Guidance Produce Consistency? A Review of Methodological Consistency in Breast Cancer Utility Value Measurement in NICE Single Technology Appraisals.

    2017-07-05

    Since 2004, National Institute for Health and Care Excellence (NICE) methodological guidance for technology appraisals has emphasised a strong preference for using the validated EuroQol 5-Dimensions (EQ-5D) quality-of-life instrument, measuring patient health status from patients or carers, and using the general public's preference-based valuation of different health states when assessing health benefits in economic evaluations. The aim of this study was to review all NICE single technology appraisals (STAs) for breast cancer treatments to explore consistency in the use of utility scores in light of NICE methodological guidance. A review of all published breast cancer STAs was undertaken using all publicly available STA documents for each included assessment. Utility scores were assessed for consistency with NICE-preferred methods and original data sources. Furthermore, academic assessment group work undertaken during the STA process was examined to evaluate the emphasis of NICE-preferred quality-of-life measurement methods. Twelve breast cancer STAs were identified, and many STAs used evidence that did not follow NICE's preferred utility score measurement methods. Recent STA submissions show companies using EQ-5D and mapping. Academic assessment groups rarely emphasized NICE-preferred methods, and queries about preferred methods were rare. While there appears to be a trend in recent STA submissions towards following NICE methodological guidance, historically STA guidance in breast cancer has generally not used NICE's preferred methods. Future STAs in breast cancer and reviews of older guidance should ensure that utility measurement methods are consistent with the NICE reference case to help produce consistent, equitable decision making.

  8. Do NICE and CHI have no interest in safety? Opinion of the book NICE, CHI and the NHS reforms. Enabling excellence or imposing control?

    Science.gov (United States)

    Fletcher, P

    2000-08-01

    Seventeen eminent and experienced people have contributed to this most valuable review of NICE and CHI and their potential impact on clinical practice in the UK. There is essentially 100% agreement that the basic concept is a good one; we all want to have the highest possible quality of clinical practice and improvements in health care. This is all motherhood and apple-pie stuff which goes without question but the problem is how it is put into effect. The contributors are also in agreement and fear that central desire for control will outweigh the benefits. The most recent NICE action, which was leaked to the media as a 'preliminary opinion', concerned the use of beta-interferon for the treatment of multiple sclerosis (MS). The opinion seems to be that beta-interferon is very expensive, that, yes, it does help some sufferers but, no, it does not help others and because it costs more than the NHS can afford no one can have it. This seems to me to be a most unsatisfactory outcome. Surely what clinical excellence demands is the refinement of diagnostic capabilities so that those who will benefit may be distinguished from those who will not. In the meantime we do the best we can even if it does mean that the NHS has to pay for some patients who do not respond. This is the inevitable consequence of the belief that a 'free' and comprehensive health service can be provided out of general taxation. Beta-interferon for the treatment of MS is an example of the observable fact that medical science is advancing at a rate considerably in excess of possible increases in funding. Possibly the most important problem identified in this book is the absence of a relevant, high quality data source for the preparation of the numerous guidelines that NICE is expected to produce each year. In a fully grown science a starting point for a quantitative procedure is the establishment of a baseline and, having done that, the scientist's next step is to produce a standard curve for use in the

    2018-01-01

    The National Institute for Health and Care Excellence (NICE) was established in 1999 to provide evidence-based guidance. The task of producing guidance by reviewing primary research data and using an advisory committee to develop evidence-based recommendations, is not straightforward. Guidance production is, however, less challenging than the task of putting evidence-based recommendations into practice.NICE is very sensitive to this challenge as, since 1999, over 1500 pieces of NICE guidance have been published. A number of pieces of guidance relate to heart disease, including pharmaceutical agents, new medical technologies and clinical guidelines. Examples include guidelines on acute heart failure and atrial fibrillation, and advice on technologies including edoxaban and implantable cardioverter defibrillators.The research evidence is clear that a change in practice rarely comes about as a result of simply disseminating guidance on best practice. Simple dissemination is particularly ineffective if the guidance has not been produced by a well-respected, credible organisation. It is also clear from the literature that implementation is more successful when more than one approach is taken, and when there is alignment between efforts at organisational, local and national levels.At an organisational level, there should be support from the Board for quality improvement, with ongoing measurement of progress. Resources should be provided for targeted change programmes, particularly where new guidance suggests improvements are required. A systematic process for putting change in place should include identifying barriers to change, agreeing interventions to overcome the barriers and drive forward improvement and planning for implementation and evaluation. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

  14. The NICE ADHD health technology assessment: A review and critique

    2008-01-01

    Full Text Available Abstract Background Health technology assessments (HTAs by the National Institute for Health and Clinical Excellence (NICE enjoy high levels of international attention. The present analysis addresses NICE's appraisal of methylphenidate, atomoxetine and dexamphetamine for attention-deficit/hyperactivity disorder (ADHD in children and adolescents, published in March 2006. Methods A qualitative study of NICE Technology Appraisal No. 98 was done focusing on the >600-page technology assessment report, which aimed at evaluating ADHD treatment strategies by a clinical effectiveness review and an economic analysis using meta-analytical techniques and a cost-effectiveness model. Results The technology assessment was unable to differentiate between the various drugs in terms of efficacy, and its economic model was ultimately driven by cost differences. While the assessment concluded that the economic model "clearly identified an optimal treatment strategy" with first-line dexamphetamine, the NICE appraisal committee subsequently found it impossible to distinguish between the different strategies on grounds of cost-effectiveness. Analyzing the assessment reveals gaps and inconsistencies concerning data selection (ultimately relying on a small number of short-term studies only, data synthesis (pooling of heterogeneous study designs and clinical endpoints, and economic model structure (identifying double-counting of nonresponders as a likely source of bias, alongside further methodological anomalies. Conclusion Many conclusions of the NICE technology assessment rest on shaky grounds. There remains a need for a new, state-of-the-art systematic review of ADHD treatment strategies including economic evaluation, which ideally should address outcomes beyond children's health-related quality of life, such as long-term sequelae of the disorder and caregiver burden.

    2018-01-01

    Value assessment frameworks have gained prominence recently in the context of U.S. healthcare. Such frameworks set out a series of factors that are considered in funding decisions. The UK's National Institute of Health and Care Excellence (NICE) is an established health technology assessment (HTA) agency. We present a novel application of text analysis that characterizes NICE's Technology Appraisals in the context of the newer assessment frameworks and present the results in a visual way. A total of 243 documents of NICE's medicines guidance from 2007 to 2016 were analyzed. Text analysis was used to identify a hierarchical set of decision factors considered in the assessments. The frequency of decision factors stated in the documents was determined and their association with terms related to uncertainty. The results were incorporated into visual representations of hierarchical factors. We identified 125 decision factors, and hierarchically grouped these into eight domains: Clinical Effectiveness, Cost Effectiveness, Condition, Current Practice, Clinical Need, New Treatment, Studies, and Other Factors. Textual analysis showed all domains appeared consistently in the guidance documents. Many factors were commonly associated with terms relating to uncertainty. A series of visual representations was created. This study reveals the complexity and consistency of NICE's decision-making processes and demonstrates that cost effectiveness is not the only decision-criteria. The study highlights the importance of processes and methodology that can take both quantitative and qualitative information into account. Visualizations can help effectively communicate this complex information during the decision-making process and subsequently to stakeholders.

    2011-07-01

    The National Institute for Health and Clinical Excellence (NICE) has recently reviewed optimal means of early recognition and initial management of ovarian cancer, the leading cause of gynaecological death in the UK. The NICE guidelines state that general practitioners should measure serum CA125 in women presenting with persistent and continuous symptoms suggestive of ovarian cancer (e.g. abdominal distension, early satiety and loss of appetite or pelvic pain). If CA125 is ≥35 kU/L, the general practitioner should arrange an ultrasound scan of the abdomen and pelvis to enable calculation of the risk of malignancy score (RMI). Women with an RMI score of ≥250 should then be referred to a specialist multidisciplinary team. Successful implementation of these guidelines requires close liaison between primary care and laboratory medicine to ensure that CA125 is requested as a diagnostic aid only for women meeting the criteria stated in the guidelines. Preanalytical criteria must also be met and it is essential that both requestors and patients be aware of other possible causes of increases in CA125, as well as the fact that it is not raised in all patients with ovarian cancer. Guidance is being prepared to enable appropriate interpretation and implementation of the NICE guidelines. Continuous audit of the outcomes will also be essential to determine the effectiveness of this approach to early detection of ovarian cancer.

  17. Can the NICE "end-of-life premium" be given a coherent ethical justification?

    Cookson, Richard

    2013-12-01

    In 2009 the UK National Institute for Health and Clinical Excellence (NICE) announced that its health technology appraisal committees would henceforth give special additional weight to health gains from life-extending end-of-life treatments. This was a response to mounting concern from NICE's stakeholders that effective new drugs for end-stage cancer often fail NICE's standard test of cost effectiveness. This change of policy may be justifiable on procedural grounds as the result of a democratic political process responding to stakeholder concerns. However, according to the "accountability for reasonableness" framework proposed by the philosopher Norman Daniels and endorsed by NICE, there also needs to be transparency about the substantive ethical grounds for public health care resource allocation decisions. In that spirit, I analyze eleven potentially relevant justifications for the NICE "end-of-life premium," drawn from the economics and philosophy literature: (1) rule of rescue, (2) fair chances, (3) ex post willingness to pay, (4) caring externality, (5) financial protection, (6) symbolic value, (7) diminishing marginal value of future life years, (8) concentration of benefits, (9) dread, (10) time to set your affairs in order, and (11) severity of illness. I conclude that none of them yields a coherent ethical justification for the NICE end-of-life premium.

    2018-05-17

    The National Institute for Health and Care Excellence (NICE) Medical Technologies Evaluation Programme (MTEP) promotes the adoption of innovative diagnostic and therapeutic technologies into National Health Service (NHS) clinical practice through the publication of guidance and briefing documents. Since the inception of the programme in 2009, there have been 7 medical technologiesguidance, 3 diagnostics guidance and 23 medtechinnovation briefing documents published that are relevant to the heart and circulation. Medical technologies guidance is published by NICE for selected single technologies if they offer plausible additional benefits to patients and the healthcare system. Diagnostic guidance is published for diagnostic technologies if they have the potential to improve health outcomes, but if their introduction may be associated with an increase in overall cost to the NHS. Medtechinnovation briefings provide evidence-based advice to those considering the implementation of new medical devices or diagnostic technologies. This review provides reference to all of the guidance and briefing medical technology documents that NICE has published that are relevant to the heart and circulation and reflect on their diverse recommendations. The interaction of MTEP with other NICE programmes is integral to its effectiveness and the means by which consistency is ensured across the different NICE programmes is described. The importance of the input of clinical experts from the cardiovascular professional community and the engagement by NICE with cardiovascular professional societies is highlighted as being fundamental to ensuring the quality of guidance outputs as well as to promoting their implementation and adoption. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    2018-04-15

    The 2014 National Institute of Clinical Excellence (NICE) guidelines on the management of acute heart failure recommended using a plasma NT-proBNP threshold of 300pg/ml to assist in ruling out the diagnosis of heart failure (HF), updating previous guidelines recommending using a threshold of 400pg/ml. NICE based their recommendations on 6 studies performed in other countries. This study sought to determine the diagnostic and economic implications of using these thresholds in a large unselected UK population. Patient and clinical demographics were recorded for all consecutive suspected HF patients over 12months, as well as clinical outcomes including time to HF hospitalisation and time to death (follow up 15.8months). Of 1995 unselected patients admitted with clinically suspected HF, 1683 (84%) had a NTproBNP over the current NICE recommended threshold, of which 35% received a final diagnosis of HF. Lowering the threshold from 400 to 300pg/ml would have involved screening an additional 61 patients and only would have identified one new patient with HF (sensitivity 0.985, NPV 0.976, area under the curve (AUC) at 300pg/ml 0.67; sensitivity 0.983, NPV 0.977, AUC 0.65 at 400pg/ml). The economic implications of lowering the threshold would have involved additional costs of £42,842.04 (£702.33 per patient screened, or £ 42,824.04 per new HF patient). Applying the recent updated NICE guidelines to an unselected real world population increases the AUC but would have a significant economic impact and only identified one new patient with heart failure.

    2015-01-01

    Concern with the threshold applied in cost-effectiveness analyses by bodies such as NICE distracts attention from their biased use of the principle. The bias results from the prior requirement that an intervention be effective (usually 'clinically effective') before its cost-effectiveness...... is considered. The underlying justification for the use of cost-effectiveness as a criterion, whatever the threshold adopted, is that decisions in a resource-constrained system have opportunity costs. Their existence rules out any restriction to those interventions that are 'incrementally cost-effective......' at a chosen threshold and requires acceptance of those that are 'decrementally cost-effective' at the same threshold. Interventions that fall under the linear ICER line in the South-West quadrant of the cost-effectiveness plane are cost-effective because they create net health benefits, as do those...

    M.A. The Nice Guy Paradox is a provocative perception that is commonly expressed within society and the mass media. According to this perception, nice guys are less successful in their relationships with women than other men. The Nice Guy Paradox causes much frustration and confusion for self-proclaimed nice guys. In addition, the implications of this perception may negatively influence the way in which men relate to women. For instance, the Nice Guy Paradox implies that if men want to be ...

    2008-01-01

    Aim: To assess the impact of the introduction of the Birmingham Children's Hospital (BCH) head injury computed tomography (CT) guidelines, when compared with the National Institute of Health and Clinical Excellence (NICE) guidelines, on the number of children with head injuries referred from the Emergency Department (ED) undergoing a CT examination of the head. Material and methods: All children attending BCH ED over a 6-month period with any severity of head injury were included in the study. ED case notes were reviewed and data were collected on a specifically designed proforma. Indications for a CT examination according to both NICE and BCH head injury guidelines and whether or not CT examinations were performed were recorded. Results: A total of 1428 children attended the BCH ED following a head injury in the 6-month period. The median age was 4 years (range 6 days to 15 years) and 65% were boys. Four percent of children were referred for a CT using BCH guidelines and were appropriately examined. If the NICE guidelines had been strictly adhered to a further 8% of children would have undergone a CT examination of the head. All of these children were discharged without complication. The remaining 88% had no indication for CT examination by either BCH or NICE and appropriately did not undergo CT. Conclusions: Adherence to the NICE head injury guidelines would have resulted in a three-fold increase in the total number of CT examinations of the head. The BCH head injury guidelines are both safe and appropriate in the setting of a large children's hospital experienced in the management of children with head injuries

    In 2010, guidelines published by the National Institute for Clinical Excellence (NICE) suggested a change in the way patients with stable chest pain of suspected cardiac origin were investigated. These guidelines removed exercise treadmill testing from routine use and introduced cardiac CT to regular use. To investigate whether these guidelines had improved our service provision by reducing the number of further investigations required to make a diagnosis, and to see if our costs had increased now that the less expensive exercise treadmill tests were not recommended. Clinic letters were used to assess patients pretest likelihood of coronary artery disease for two six-month cohorts of consecutive patients seen in the rapid access chest pain clinic (January-June 2010 and July-December 2011) using NICE published methodology, and to ascertain which investigations patients had. Using NICE modelled costs, we generated comparative hypothetical costs for each cohort and an average cost per patient. In the January-June 2010 cohort, 435 patients with chest pain were seen, and in July-December 2011, 334 patients were seen. In the pre-NICE guidelines cohort, 23% of patients required two investigations as compared with 11.4% in the post-NICE guidelines cohort, with no patient requiring three investigations as compared with 3% in the original cohort. There was no significant increase in costs per patient in the post-NICE guidance group. Implementing NICE guidance reduced the number of investigations needed per patient, and did not prove more expensive for our department in the short term.

    The purpose of this study was to evaluate the applicability of the National Institute for Health and Clinical Excellence (NICE) guidelines for imaging studies in children under the age of three with first urinary tract infection (UTI). In our cohort of 112 patients, we gathered data regarding the occurrence of indications for ultrasonography (US) and voiding cystourethrography (VCUG) according to the NICE guidelines, dimercaptosuccinic acid (DMSA) scintigraphy examinations, UTI recurrence, antimicrobial prophylaxis (AMP), anti-reflux procedures, and other urological procedures. If the NICE guidelines had been applied, 13 of the 25 patients (52 %) with vesicoureteral reflux (VUR), including 6 of the 12 patients (50 %) with dilating VUR and 3 of the 4 patients who underwent endoscopic anti-reflux treatment, would have been missed, and a negative VCUG would have been avoided in 25 of the 42 patients (60 %) with no VUR. None of the missed diagnoses occurred in the younger boys' group. Based on these preliminary analyses, we feel that the NICE guidelines for imaging studies in children under 3 years old with UTI may be applicable to clinical use only in boys under 6 months of age. For other patients the guidelines were unsuccessful.

    The Nuclear Energy Advanced Modeling and Simulation program (NEAMS) from the Department of Energy s Office of Nuclear Energy has funded the development of a modeling and simulation workflow environment to support the various codes in its nuclear energy scientific computing toolkit. This NEAMS Integrated Computational Environment (NiCE) provides extensible tools and services that enable efficient code execution, input generation, pre-processing visualizations, and post-simulation data analysis and visualization for a large portion of the NEAMS Toolkit. A strong focus for the NiCE development team throughout FY 2015 has been support for the Multiphysics Object Oriented Simulation Environment (MOOSE) and the NEAMS nuclear fuel performance modeling application built on that environment, BISON. There is a strong desire in the program to enable and facilitate the use of BISON throughout nuclear energy research and industry. A primary result of this desire is the need for strong support for BISON in NiCE. This report will detail improvements to NiCE support for BISON. We will present a new and improved interface for interacting with BISON simulations in a variety of ways: (1) improved input model generation, (2) embedded mesh and solution data visualizations, and (3) local and remote BISON simulation launch. We will also show how NiCE has been extended to provide support for BISON code development.

    The National Institute for Health and Care Excellence (NICE) invited the manufacturer of ruxolitinib (Novartis) to submit clinical and cost-effectiveness evidence for ruxolitinib within its licensed indication (the treatment of disease-related splenomegaly or symptoms in adult patients with myelofibrosis), according to the Institute's Single Technology Appraisal process. The Centre for Reviews and Dissemination and Centre for Health Economics at the University of York were commissioned to act as the independent Evidence Review Group (ERG). This article provides a description of the company submission, the ERG review and the resulting NICE guidance TA289 issued in June 2013. The ERG critically reviewed the evidence presented in the manufacturer's submission and identified areas requiring clarification, for which the manufacturer provided additional evidence. The main clinical effectiveness data were derived from two phase III, multicentre, randomised controlled trials (RCTs): Controlled myelofibrosis study with oral JAK inhibitor treatment (COMFORT)-II compared ruxolitinib with best available therapy (BAT), and COMFORT-I compared ruxolitinib with placebo. These RCTs demonstrated that ruxolitinib confers significant benefits in terms of spleen size reduction and improvement in symptom burden. In the COMFORT-II trial, a reduction in spleen volume of ≥35 % was achieved in 28 % of ruxolitinib-treated patients compared with 0 % of patients in the BAT group (p Service (NHS) resources for treating disease-related splenomegaly or symptoms in adults with myelofibrosis. Ruxolitinib is not recommended for the treatment of disease-related splenomegaly or symptoms in adult patients with primary myelofibrosis (also known as chronic idiopathic myelofibrosis), post-polycythaemia vera myelofibrosis and post-essential thrombocythaemia myelofibrosis in NICE TA289.

    The Multiphysics Object-Oriented Simulation Environment (MOOSE) is a framework that facilitates the development of applications that rely on finite-element analysis to solve a coupled, nonlinear system of partial differential equations. RELAP-7 represents an update to the venerable RELAP-5 simulator that is built upon this framework and attempts to model the balance-of-plant concerns in a full nuclear plant. This report details the continued support and integration of RELAP-7 and the NEAMS Integrated Computational Environment (NiCE). RELAP-7 is fully supported by the NiCE due to on-going work to tightly integrate NiCE with the MOOSE framework, and subsequently the applications built upon it. NiCE development throughout the first quarter of FY15 has focused on improvements, bug fixes, and feature additions to existing MOOSE-based application support. Specifically, this report will focus on improvements to the NiCE MOOSE Model Builder, the MOOSE application job launcher, and the 3D Nuclear Plant Viewer. This report also includes a comprehensive tutorial that guides RELAP-7 users through the basic NiCE workflow: from input generation and 3D Plant modeling, to massively parallel job launch and post-simulation data visualization.

    Full Text Available Most of the traditional IT/IS performance measures are based on productivity and process, which mainly focus on method of investment appraisal. There is a need to produce alternative holistic measurement models that enable soft and hard issues to be measured qualitatively. A New IT/IS Capability Evaluation (NICE framework has been designed to measure the capability of organisations to'successfully implement IT systems' and it is applicable across industries.The idea is to provide managers with measurement tools to enable them to identify where improvements are required within their organisations and to indicate their readiness prior to IT investment. The NICE framework investigates four organisational key elements: IT, Environment, Process and People, and is composed of six progressive stages of maturity that a company can achieve its IT/IS capabilities. For each maturity stage, the NICE framework describes a set of critical success factors that must be in place for the company to achieve each stage.

  14. Sunlit Uplands: The Genius of the NICE Reference Case

    Directory of Open Access Journals (Sweden)

    Paul C Langley

    2016-07-01

    Full Text Available The NICE reference case has received widespread acceptance in health technology assessment. The lifetime cost-per-QALY model and constructed claims for product impact have been widely emulated in country-specific guidelines for formulary submission as well as in publications in the leading health technology journals. Unfortunately, from the perspective of the standards of normal science, adherence to the reference case standard means that the claims made are typically non-evaluable. They have to be taken at face value. They may suggest potential evaluable hypotheses for clinical and cost-effectiveness claims, but there is no requirement in the reference case for claims to be put in an evaluable form and for manufacturers to suggest possible protocols for product impact assessment. This is not an acceptable situation. Absent the standards for falsification and replication, which are at the core of the scientific method, we have no idea whether the claims accepted by NICE are right or even if they are wrong. If we accept the reference case paradigm should we conclude that the sunlit uplands of formulary decisions based on non-evaluable simulated claims for cost-effectiveness has been reached? Have we rejected natural selection in favor of intelligent design? Conflict of Interest None Type: Commentary

    2008-08-01

    The National Institute for Health and Clinical Excellence (NICE) issued guidance on surgical techniques for tonsillectomy during a national audit of surgical practice and postoperative complications. To assess the impact of the guidance on tonsillectomy practice and outcomes. An interrupted time-series analysis of routinely collected Hospital Episodes Statistics data, and an analysis of longitudinal trends in surgical technique using data from the National Prospective Tonsillectomy Audit. Patients undergoing tonsillectomy in English NHS hospitals between January 2002 and December 2004. Postoperative haemorrhage within 28 days. The rate of haemorrhage increased by 0.5% per year from 2002, reaching 6.4% when the guidance was published. After publication, the rate of haemorrhage fell immediately to 5.7% (difference 0.7%: 95% CI -1.3% to 0.0%) and the rate of increase appeared to have stopped. Data from the National Prospective Tonsillectomy Audit showed that the fall coincided with a shift in surgical techniques, which was consistent with the guidance. NICE guidance influenced surgical tonsillectomy technique and in turn produced an immediate fall in postoperative haemorrhage. The ongoing national audit and strong support from the surgical specialist association may have aided its implementation.

    Over recent years, the Arctic Ocean region has shifted towards a younger and thinner sea-ice regime. The Norwegian young sea ICE (N-ICE2015) expedition was designed to investigate the atmosphere-snow-ice-ocean interactions in this new ice regime north of Svalbard. Here we analyze upper-air measurements made by radiosondes launched twice daily together with surface meteorology observations during N-ICE2015 from January to June 2015. We study the multiple cyclonic events observed during N-ICE2015 with respect to changes in the vertical thermodynamic structure, sudden increases in moisture content and temperature, temperature inversions and boundary layer dynamics. The influence of synoptic cyclones is strongest under polar night conditions, when radiative cooling is most effective and the moisture content is low. We find that transitions between the radiatively clear and opaque state are the largest drivers of changes to temperature inversion and stability characteristics in the boundary layer during winter. In spring radiative fluxes warm the surface leading to lifted temperature inversions and a statically unstable boundary layer. The unique N-ICE2015 dataset is used for case studies investigating changes in the vertical structure of the atmosphere under varying synoptic conditions. The goal is to deepen our understanding of synoptic interactions within the Arctic climate system, to improve model performance, as well as to identify gaps in instrumentation, which precludes further investigations.

    The National Institute for Health and clinical Excellence (NICE) depression guideline (2004) and the updated Quality and Outcomes Framework (QOF) (2006) in general practice have introduced the concepts of screening severity assessment, for example using the Patient Health Questionnaire 9 (PHQ-9), and 'stepped care' for depression. To explore primary care practitioner perspectives on the clinical utility of the NICE guideline and the impact of the QOF on diagnosis and management of depression in routine practice. Qualitative study using focus groups from four multidisciplinary practice teams with diverse populations in south Yorkshire. Four focus groups were conducted, using a topic guide and audiotaping. There were 38 participants: GPs, nurses, doctors in training, mental health workers, and a manager. Data analysis was iterative and thematic. The NICE guideline, with its embedded principles of holism and evidence-based practice, was viewed positively but its impact was compromised by resource and practitioner barriers to implementation. The perceived imposition of the screening questions and severity assessments (PHQ-9) with no responsive training had required practitioners to work hard to minimise negative impacts on their work, for example: constantly adapting consultations to tick boxes; avoiding triggering open displays of distress without the time to offer appropriate care; positively managing how their patients were labelled. Further confusion was experienced around the evolving content of psychological interventions for depression. Organisational barriers to the implementation of the NICE guideline and the limited scope of the QOF highlight the need for policy makers to work more effectively with the complex realities of general practice in order to systematically improve the quality and delivery of 'managed' care for depression.

    Despite increasing prevalence of obesity, no country has successfully implemented comprehensive pathways to provide advice to all the severely obese patients that seek treatment. We aimed to formulate pathways for referral into and out of weight assessment and management clinics (WAMCs) that include internal medicine/primary care physicians as part of a multidisciplinary team that could provide specialist advice and interventions, including referral for bariatric surgery. Using a National Institute of Health and Care Excellence (NICE)-accredited process, a Guidance Development Group conducted a literature search identifying existing WAMCs. As very few examples of effective structures and clinical pathways existed, the current evidence base for optimal assessment and management of bariatric surgery patients was used to reach a consensus. The model we describe could be adopted internationally by health services to manage severely obese patients.

    2013-01-01

    The National Institute for Health and Clinical Excellence (NICE) has recently released obesity guidelines for health risk. For the first time in the UK, we estimate the utility of these guidelines by relating them to the established cardiovascular disease (CVD) risk factors. Health Survey for England (HSE) 2006, a population-based cross-sectional study in England was used with a sample size of 7225 men and women aged ≥35 years (age range: 35-97 years). The following CVD risk factor outcomes were used: hypertension, diabetes, total and high density lipoprotein cholesterol, glycated haemoglobin, fibrinogen, C-reactive protein and Framingham risk score. Four NICE categories of obesity were created based on body mass index (BMI) and waist circumference (WC): no risk (up to normal BMI and low/high WC); increased risk (normal BMI & very high WC, or obese & low WC); high risk (overweight & very high WC, or obese & high WC); and very high risk (obese I & very high WC or obese II/III with any levels of WC. Men and women in the very high risk category had the highest odds ratios (OR) of having unfavourable CVD risk factors compared to those in the no risk category. For example, the OR of having hypertension for those in the very high risk category of the NICE obesity groupings was 2.57 (95% confidence interval 2.06 to 3.21) in men, and 2.15 (1.75 to 2.64) in women. Moreover, a dose-response association between the adiposity groups and most of the CVD risk factors was observed except total cholesterol in men and low HDL in women. Similar results were apparent when the Framingham risk score was the outcome of interest. In conclusion, the current NICE definitions of obesity show utility for a range of CVD risk factors and CVD risk in both men and women.

    The National Institute for Health and Clinical Excellence (NICE) invited the manufacturer (The Medicines Company) of bivalirudin to submit evidence for its clinical and cost effectiveness within its licensed indication for the treatment of adults with ST-segment elevation myocardial infarction (STEMI) intended for primary percutaneous coronary intervention (PPCI), as part of NICE's single technology appraisal (STA) process. The School of Health and Related Research (ScHARR) at the University of Sheffield was commissioned to act as the Evidence Review Group (ERG), which produced a review of the evidence within the manufacturer's submission to NICE. This article describes the manufacturer's submission, the ERG review and NICE's subsequent decisions. The main evidence was derived from one randomized controlled trial (RCT) of STEMI patients intended for PPCI, comparing bivalirudin with unfractionated heparin plus glycoprotein IIb/IIIa inhibitors (GPIs). Bivalirudin was associated with a significant reduction in cardiac mortality at 30 days (p = 0.03) and at 1-year follow-up (p = 0.005), and a significant reduction in major bleeding at 30 days (p plus GPI. Stent thrombosis up to 24 hours following PPCI was significantly (p target vessel for ischaemia (p = 0.18 and p = 0.12, respectively). There were two decision-analytic models: the base-case scenario used 1-year follow-up data from the RCT; and a sensitivity analysis used 3-year follow-up data. Resource use was primarily drawn from this RCT. Health-related quality-of-life (HR-QOL) estimates were drawn from a UK cohort study. Both models evaluated the incremental costs and outcomes of bivalirudin compared with heparin plus GPI for patients with STEMI intended for PPCI. The analysis adopted a UK NHS perspective over a lifetime horizon. Unit costs were based on year 2009-2010 prices. The model adopted a decision-tree structure to reflect initial events for the initial period (stroke, repeat MI, minor

    2017-08-01

    Decisions made by the National Institute for Health and Care Excellence (NICE) exert an influence on the allocation of resources within 'fixed' National Health Service budgets. Yet guidance for different types of health interventions is handled via different 'programmes' within NICE, which follow different methods and processes. The objective of this research was to identify differences in the processes and methods of NICE health technology assessment programmes and to explore how these could impact on allocative efficiency within the National Health Service. Data were extracted from the NICE technology appraisal programme, medical technologies guidance, diagnostic assessment programme, highly specialised technologies programme, and clinical guidelines process and methods manuals to undertake a systematic comparison. Five qualitative interviews were carried out with NICE members of staff and committee members to explore the reasons for the differences found. The main differences identified were in the required evidence review period, or lack thereof, mandatory funding status, the provision of a reference case for economic evaluation, the requirement for and the type of economic analysis undertaken, and the decision making criteria used for appraisal. Many of the differences found can be justified on grounds of practicality and relevance to the health technologies under assessment. Nevertheless, from a strict utilitarian view, there are several potential areas of inefficiency that could lead to the misallocation of resources within the National Health Service, although some of these might be eliminated or reduced if an egalitarian view is taken. The challenge is determining where society is willing to trade health gains between different people.

    To determine the effectiveness of a model osteoarthritis consultation, compared with usual care, on physical function and uptake of National Institute for Health and Care Excellence (NICE) osteoarthritis recommendations, in adults ≥45 years consulting with peripheral joint pain in UK general practice. Two-arm cluster-randomised controlled trial with baseline health survey. Eight general practices in England. 525 adults ≥45 years consulting for peripheral joint pain, amongst 28,443 population survey recipients. Four intervention practices delivered the model osteoarthritis consultation to patients consulting with peripheral joint pain; four control practices continued usual care. The primary clinical outcome of the trial was the SF-12 physical component score (PCS) at 6 months; the main secondary outcome was uptake of NICE core recommendations by 6 months, measured by osteoarthritis quality indicators. A Linear Mixed Model was used to analyse clinical outcome data (SF-12 PCS). Differences in quality indicator outcomes were assessed using logistic regression. 525 eligible participants were enrolled (mean age 67.3 years, SD 10.5; 59.6% female): 288 from intervention and 237 from control practices. There were no statistically significant differences in SF-12 PCS: mean difference at the 6-month primary endpoint was -0.37 (95% CI -2.32, 1.57). Uptake of core NICE recommendations by 6 months was statistically significantly higher in the intervention arm compared with control: e.g., increased written exercise information, 20.5% (7.9, 28.3). Whilst uptake of core NICE recommendations was increased, there was no evidence of benefit of this intervention, as delivered in this pragmatic randomised trial, on the primary outcome of physical functioning at 6 months.

    2002-01-01

    Information has become a commodity particularly important to industry, science, and politics. Information becomes critical because of its rapid change. The basis and the catalyst of this change in information are the information technologies now available, and the Internet with its varied contents. This makes the Internet a new market place which, although it is open, can quickly turn into an information maze because of its sheer volume. Also the nuclear industry must find its way through this maze. eNICE was created in order to build a bridge between the flood of information in the Internet and the information really needed in a specific case. eNICE (e stands for electronic, and NICE stands for Nuclear Information Compendium Europe), a living Internet-based nuclear compendium in the English language, is a unique combination of a broad spectrum of information and data about the use of nuclear power in Europe.

    • To investigate whether the implementation of the August 2007 National Institute for Health and Clinical Excellence (NICE) guidelines would miss significant urinary tract pathology in children with urinary tract infection (UTI). • All ultrasound (US) performed in children aged >6 months, during the year 1 August 2006 to 31 July 2007 for UTI, were retrospectively studied. • Each US scan in the study population of 346 was categorised dependent on whether it was appropriate or inappropriate to have been performed under the new guidelines and whether the US scan was normal or abnormal. • The records of each patient with an inappropriate abnormal US scan were re-analysed to see if patient management was affected by the US scan. • In 2011 patients with an original inappropriate abnormal US scan were re-evaluated to identify if any had presented with further urinary pathology. • In accordance with the NICE guidelines patients were divided by age. • Children aged 0.5-3 years: 78/95 (82%) US scans were inappropriate of which 12 (15%) were abnormal and four of these had a further documented UTI. After careful assessment of the US abnormalities it was judged that only one would have benefited from the initial US scan. • Children aged >3 years: 146/251 (58%) US scans were inappropriate of which 21(14%) were abnormal and six of these (29%) had a further documented UTI. After careful assessment of the US abnormalities it was judged that only three of 21 (14%) would have benefited from the initial US scan. • The vast majority of anomalies detected on the inappropriate US scans were of little clinical significance. • It is difficult to identify any patient who would have been truly disadvantaged if the US scan had not been performed after the initial UTI. • The NICE guidelines are safe to follow. © 2011 THE AUTHORS.

    Aim: To determine the potential effect of changes to the National Institute for Health and Care Excellence (NICE) guidelines to the use of computed tomography (CT) in the assessment of suspected paediatric cervical spine (c-spine) injury. Material and methods: A 5 year retrospective study was conducted of c-spine imaging in paediatric (<10 years) patients presenting following blunt trauma at a Level 1 trauma centre in London. All patients under the age of 10 years who underwent any imaging of the c-spine following blunt trauma were included. Clinical data relating to the presenting signs and symptoms were obtained from the retrospective review of electronic records and paper notes. This was then applied to the previous NICE guideline (CG56) and to the new NICE guideline (CG176). Patients with incomplete data were excluded. Results: Two hundred and seventy-eight patients <10 years underwent imaging of the c-spine following blunt trauma. Two hundred and seventy (97.12%) examinations had complete data and were included in further analysis. One hundred and forty-nine (55.19%) met the criteria for a CT of the c-spine under NICE CG56, whereas 252 (93.33%) met the updated NICE CG176 criteria for c-spine CT. Five (1.85%) patients had a c-spine injury and met the criteria under both CG56 and CG176 NICE guidelines. Conclusion: Recent changes to NICE Head Injury Guidelines relating to radiological assessment of paediatric c-spine following blunt trauma are likely to result in an increased usage of CT as the initial radiological investigation over plain radiographs, without an apparent increase in specificity in the present series. - Highlights: • Paediatric CSI is a rare but serious consequence of blunt trauma. • New NICE 176 criteria broadened the criteria for c-spine CT following trauma. • 69% more patients may be eligible for assessment with CT under new guidelines. • 5 cases of CSI occurred in this series of 278 paediatric trauma cases. • All 5 cases met CG176

    The Department of Energy Office of Nuclear Energy's Nuclear Energy Advanced Modeling and Simulation (NEAMS) program has supported the development of the NEAMS Integrated Computational Environment (NiCE), a modeling and simulation workflow environment that provides services and plugins to facilitate tasks such as code execution, model input construction, visualization, and data analysis. This report details the development of workflows for the reactor core neutronics application, PROTEUS. This advanced neutronics application (primarily developed at Argonne National Laboratory) aims to improve nuclear reactor design and analysis by providing an extensible and massively parallel, finite-element solver for current and advanced reactor fuel neutronics modeling. The integration of PROTEUS-specific tools into NiCE is intended to make the advanced capabilities that PROTEUS provides more accessible to the nuclear energy research and development community. This report will detail the work done to improve existing PROTEUS workflow support in NiCE. We will demonstrate and discuss these improvements, including the development of flexible IO services, an improved interface for input generation, and the addition of advanced Fortran development tools natively in the platform.

    The healthcare system in the UK, essentially the NHS, is an open economic system subject to the same pressures as any other economic system. The pressures concern limited resources coupled with powerful drivers for increasing spending: invention, demography and inflation. There have only ever been three types of economic system: steady state (everything, as in a feudal system, stays as it was the year before), market capitalism (supply and demand are allowed to find their own equilibrium) and some version of central planning. In healthcare, most advanced countries favour the last of the three. This is for three reasons: distribution (not only are the poor less able to pay for sickness, but sickness exacerbates poverty), information (markets operate poorly when providers can easily outsmart customers) and externalities (it is in the interest of everyone that infectious diseases and the other knock-on consequences of ill health are ameliorated). So in the UK, the state, with a good deal of cross-party consensus, directs most of health service supply. This system has become more complex over the decades since the formation of the NHS in 1948. A notable element of the complexity is the regulation of the introduction of new technologies. A key element of the regulatory system has been the National Institute for Health and Clinical Excellence (NICE), and a key aspect of NICE's decisions has been not just value, but also value for money. This has not been without controversy.

    As part of its single technology appraisal (STA) process, the National Institute for Health and Care Excellence (NICE) invited the manufacturer (UCB Pharma) of certolizumab pegol (CZP; Cimzia ® ) to submit evidence of its clinical and cost effectiveness for the treatment of rheumatoid arthritis (RA) following inadequate response to a tumour necrosis factor-α inhibitor (TNFi). The School of Health and Related Research Technology Appraisal Group at the University of Sheffield was commissioned to act as the independent Evidence Review Group (ERG). The ERG produced a detailed review of the evidence for the clinical and cost effectiveness of the technology, based upon the company's submission to NICE. The clinical effectiveness evidence in the company's submission for CZP was based predominantly on six randomised controlled trials (RCTs) comparing the efficacy of CZP against placebo. The clinical effectiveness review identified no head-to-head evidence on the efficacy of CZP against the comparators within the scope; therefore, the company performed a network meta-analysis (NMA). The company's NMA concluded that CZP had a similar efficacy to that of its comparators. The company submitted a Markov model that assessed the incremental cost effectiveness of CZP versus comparator biologic disease-modifying antirheumatic drugs (bDMARDs) for the treatment of RA from the perspective of the National Health Service for three decision problems, each of which followed an inadequate response to a TNFi. These were (1) a comparison against rituximab (RTX) in combination with methotrexate (MTX); (2) a comparison against bDMARDs when RTX was contraindicated or withdrawn due to an adverse event; and (3) a comparison against bDMARDs when MTX was contraindicated or withdrawn due to an adverse event. Results from the company's economic evaluation showed that CZP resulted in a similar number of quality-adjusted life years (QALYs) produced at similar or lower costs compared with comparator b

    As part of its single technology appraisal (STA) process, the National Institute for Health and Care Excellence (NICE) invited the company (GlaxoSmithKline) that manufactures mepolizumab (Nucala ® ) to submit evidence on the clinical and cost effectiveness of mepolizumab for the treatment of severe eosinophilic asthma. The School of Health and Related Research Technology Appraisal Group (ScHARR-TAG) at the University of Sheffield was commissioned to act as the independent evidence review group (ERG). The ERG produced a review of the evidence for the clinical and cost effectiveness of mepolizumab as add-on to standard of care (SoC) compared with SoC and omalizumab, based upon the company's submission to NICE. The clinical-effectiveness evidence in the company's submission was based predominantly on three randomised controlled trials (DREAM, MENSA and SIRIUS) comparing add-on mepolizumab with placebo plus SoC. The relevant population was defined in terms of degree of asthma severity (four or more exacerbations in the previous year and/or dependency on maintenance oral corticosteroids [mOCS]) and degree of eosinophilia (a blood eosinophil count of ≥ 300 cells/µl in the previous year) based on post hoc subgroup analyses of the pivotal trials. Other subpopulations were considered throughout the appraisal, defined by different eosinophil measurements, number of exacerbations and dependency (or lack thereof) on mOCS. Statistically significant reductions in clinically significant exacerbations were observed in patients receiving mepolizumab compared with SoC meta-analysed across MENSA and DREAM in the modified intention-to-treat (ITT) population (rate ratio [RR] 0.51; 95% confidence interval [CI] 0.42-0.62) as well as in the relevant population (RR 0.47; 95% CI 0.36-0.62). In terms of quality of life, differences on the St. George's Respiratory Questionnaire in MENSA for add-on subcutaneous mepolizumab 100 mg vs. placebo were 7 and 7.5 units in the modified ITT and

    Various microorganisms play key roles in the Nitrogen (N) cycle. Quantitative PCR (qPCR) and PCR-amplicon sequencing of the N cycle functional genes allow us to analyze the abundance and diversity of microbes responsible in the N transforming reactions in various environmental samples. However, analysis of multiple target genes can be cumbersome and expensive. PCR-independent analysis, such as metagenomics and metatranscriptomics, is useful but expensive especially when we analyze multiple samples and try to detect N cycle functional genes present at relatively low abundance. Here, we present the application of microfluidic qPCR chip technology to simultaneously quantify and prepare amplicon sequence libraries for multiple N cycle functional genes as well as taxon-specific 16S rRNA gene markers for many samples. This approach, named as N cycle evaluation (NiCE) chip, was evaluated by using DNA from pure and artificially mixed bacterial cultures and by comparing the results with those obtained by conventional qPCR and amplicon sequencing methods. Quantitative results obtained by the NiCE chip were comparable to those obtained by conventional qPCR. In addition, the NiCE chip was successfully applied to examine abundance and diversity of N cycle functional genes in wastewater samples. Although non-specific amplification was detected on the NiCE chip, this could be overcome by optimizing the primer sequences in the future. As the NiCE chip can provide high-throughput format to quantify and prepare sequence libraries for multiple N cycle functional genes, this tool should advance our ability to explore N cycling in various samples. Importance. We report a novel approach, namely Nitrogen Cycle Evaluation (NiCE) chip by using microfluidic qPCR chip technology. By sequencing the amplicons recovered from the NiCE chip, we can assess diversities of the N cycle functional genes. The NiCE chip technology is applicable to analyze the temporal dynamics of the N cycle gene

    Aims: To compare the yield of positive computed tomography (CT) brain examinations after the implementation of the National Institute for Clinical Excellence (NICE) or the Scottish Intercollegiate Guidance Network (SIGN) guidelines, in comparable urban populations in two teaching hospitals in England and Scotland. Materials and methods: Four hundred consecutive patients presenting at each location following a head injury who underwent a CT examination of the head according to the locally implemented guidelines were compared. Similar matched populations were compared for indication and yield. Yield was measured according to (1) positive CT findings of the sequelae of trauma and (2) intervention required with anaesthetic or intensive care unit (ICU) support, or neurosurgery. Results: The mean ages of patients at the English and Scottish centres were 49.9 and 49.2 years, respectively. Sex distribution was 64.1% male and 66.4% male respectively. Comparative yield was 23.8 and 26.5% for positive brain scans, 3 and 2.75% for anaesthetic support, and 3.75 and 2.5% for neurosurgical intervention. Glasgow Coma Score (GCS) <13 (NICE) and GCS {<=}12 and radiological or clinical evidence of skull fracture (SIGN) demonstrated the greatest statistical association with a positive CT examination. Conclusion: In a teaching hospital setting, there is no significant difference in the yield between the NICE and SIGN guidelines. Both meet the SIGN standard of >10% yield of positive scans. The choice of guideline to follow should be at the discretion of the local institution. The indications GCS <13 and clinical or radiological evidence of a skull fracture are highly predictive of intracranial pathology, and their presence should be an absolute indicator for fast-tracking the management of the patient.

    BACKGROUND: The aim of this study was to establish current practices amongst general practitioners in the West of Ireland with regard to the investigation, diagnosis and management of urinary tract infection (UTI) in children and to evaluate these practices against recently published guidelines from the National Institute for Health and Clinical Excellence (NICE). METHODS: A postal survey was performed using a questionnaire that included short clinical scenarios. All general practices in a single health region were sent a questionnaire, cover letter and SAE. Systematic postal and telephone contact was made with non-responders. The data was analysed using SPSS version 15. RESULTS: Sixty-nine general practitioners were included in the study and 50 (72%) responded to the questionnaire. All respondents agreed that it is important to consider diagnosis of UTI in all children with unexplained fever. Doctors accurately identified relevant risk factors for UTI in the majority (87%) of cases. In collecting urine samples from a one year old child, 80% of respondents recommended the use of a urine collection bag and the remaining 20% recommended collection of a clean catch sample. Respondents differed greatly in their practice with regard to detailed investigation and specialist referral after a first episode of UTI. Co-amoxiclav was the most frequently used antibiotic for the treatment of cystitis, with most doctors prescribing a five day course. CONCLUSIONS: In general, this study reveals a high level of clinical knowledge amongst doctors treating children with UTI in primary care in the catchment area of County Mayo. However, it also demonstrates wide variation in practice with regard to detailed investigation and specialist referral. The common practice of prescribing long courses of antibiotics when treating lower urinary tract infection is at variance with NICE\\'s recommendation of a three day course of antibiotics for cystitis in children over three months of age when

    Several systematic reviews suggest that acupuncture is effective for knee osteoarthritis (OA), and furthermore a safe and cost-effective treatment for this condition. A recent clinical practice guideline (CPG) from the National Institute for Health and Care Excellence (NICE), in the United Kingdom, recommended against the use of acupuncture on the grounds that the effect size (ES) in comparison with sham acupuncture is too small. Safety data were not considered in the review, in addition the levels of evidence for acupuncture against other recommended therapies were not compared. Consequently, it is argued that this NICE guideline has limitations that lead to several potential biases in its evaluation of acupuncture, which were not addressed correctly: (1) NICE's prior scoping process limited its review. (2) NICE introduced the method of developing recommendations based on the consideration of which interventions make "minimal important differences" of an ES of 0.5 or greater, rather than the statistical significance of the effect of an intervention when compared with an appropriate comparison. (3) Evidence that sham acupuncture is not physiologically inert and has some level of beneficial effect, hence artificially reducing the magnitude of the ES in comparison with sham. (4) The low adverse effects profile of acupuncture. (5) Evidence from trials comparing acupuncture with usual or standard care was not considered, nor was cost-effectiveness data. (6) Lack of the usual CPG "head-to-head" comparisons between interventions. If the same criteria and methods that have been applied to acupuncture were applied to other NICE-recommended therapies for knee OA, including patient centeredness, patient education, self-management and weight loss, nonsteroidal anti-inflammatory drug (NSAIDs), and cyclooxygenase-2 inhibitor (COX-2 inhibitors), these too would no longer be recommended and opiates would become the first line of drug prescription. Given the problems with sham

    As part of the National Institute for Health and Care Excellence (NICE) single technology appraisal process, the manufacturer of crizotinib submitted evidence on the clinical and cost effectiveness of crizotinib in untreated anaplastic lymphoma kinase-positive (ALK-positive) non-small-cell lung cancer (NSCLC). Crizotinib has previously been assessed by NICE for patients with previously treated ALK-positive NSCLC (TA 296). It was not approved in this previous appraisal, but had been made available through the cancer drugs fund. As part of this new appraisal, the company included a price discount patient access scheme (PAS). The Centre for Reviews and Dissemination and Centre for Health Economics Technology Appraisal Group at the University of York was commissioned to act as the independent Evidence Review Group (ERG). This article provides a description of the company's submission and the ERG's review and summarises the resulting NICE guidance issued in August 2016. The main clinical-effectiveness data were derived from a multicentre randomised controlled trial-PROFILE 1014-that compared crizotinib with pemetrexed chemotherapy in combination with carboplatin or cisplatin in patients with untreated non-squamous ALK-positive NSCLC. In the trial, crizotinib demonstrated improvements in progression-free survival (PFS) and overall survival (OS). The company's economic model was a three-state 'area under the curve' Markov model. The base-case incremental cost-effectiveness ratio (ICER) was estimated to be greater than £50,000 per quality-adjusted life-year (QALY) gained (excluding the PAS discount). The ERG assessment of the evidence submitted by the company raised a number of concerns. In terms of the clinical evidence, the OS benefit was highly uncertain due to the cross-over permitted in the trial and the immaturity of the data; only 26% of events had occurred by the data cut-off point. In the economic modelling, the most significant concerns related to the analysis

    2016-12-01

    Full Text Available Background: Legislation preventing smoking in public places was introduced in England in July 2007. Since then, smoke-free policies have been extended to the majority of hospitals including those providing cancer therapies. Whilst studies have been conducted on the impact and effectiveness of hospital smoke-free policy in the UK and other countries, there have not been any studies with a focus on cancer care providers. Cancer patients are a priority group for smoking cessation and support and this study aimed to examine implementation of the National Institute Clinical Excellence (NICE guidance (PH48 in acute cancer care trusts in the UK. Methods: Participants were recruited from UK radiotherapy and chemotherapy departments (total 80 sites, 65 organisations and asked to complete a 15 min online questionnaire exploring the implementation of NICE guidance at their hospital site. Results: Considerable variability in implementation of the NICE guidance was observed. A total of 79.1% trusts were smoke-free in theory; however, only 18.6% were described as smoke-free in practice. Areas of improvement were identified in information and support for patients and staff including in Nicotine Replacement Therapy (NRT provision, staff training and clarity on e-cigarette policies. Conclusions: While some trusts have effective smoke-free policies and provide valuable cessation support services for patients, improvements are required to ensure that all sites fully adopt the NICE guidance.

  5. An evaluation of the effect that the implementation of the NICE rules may have on a diagnostic imaging department for the early management of head injuries

    2007-01-01

    Introduction: Guidelines by the National Institute of Clinical Excellence (NICE) for the early management of minor head injuries initiate the use of computed tomography (CT) for patients who may be at risk of developing intracranial haematoma. This retrospective study was designed to evaluate the effect the implementation of the NICE guidelines would have on the diagnostic imaging department of a local district general hospital. The main objective was to establish if there would be an increase in the number of CT head referrals for patients with minor head injuries. Secondly to assess how the implementation of these guidelines would affect the workload to the diagnostic imaging department in terms of cost and time, and to discuss the issue of radiation dose to patients. Method: A sample of 100 patients who were referred from the Accident and Emergency department (A and E) for plain skull radiographs, over a 4-month period were selected. The clinical information on each of these patients' was then extracted and a data collection sheet was to assess each patient according to the NICE criteria. Results and conclusion: The study found an 18% (n = 100) increase in the referral rate for CT heads for patients presenting with minor head injuries. It was also found that the use of these guidelines would mean a decrease in cost to the diagnostic imaging department of Pounds 324. Furthermore a saving of 10 h of radiographers' time was established, although the effective radiation dose to patients would be increased by 29 mSv. The NICE guidelines have proved efficient in identifying patients with intracranial damage although this coincides with an 18% (n = 100) increase in referral rates for CT and increased radiation dose to patients. However, the use of these guidelines would reduce workload to the diagnostic imaging department in terms of cost and time

    To determine how we define good practice in sensitivity analysis in general and probabilistic sensitivity analysis (PSA) in particular, and to what extent it has been adhered to in the independent economic evaluations undertaken for the National Institute for Health and Clinical Excellence (NICE) over recent years; to establish what policy impact sensitivity analysis has in the context of NICE, and policy-makers' views on sensitivity analysis and uncertainty, and what use is made of sensitivity analysis in policy decision-making. Three major electronic databases, MEDLINE, EMBASE and the NHS Economic Evaluation Database, were searched from inception to February 2008. The meaning of 'good practice' in the broad area of sensitivity analysis was explored through a review of the literature. An audit was undertaken of the 15 most recent NICE multiple technology appraisal judgements and their related reports to assess how sensitivity analysis has been undertaken by independent academic teams for NICE. A review of the policy and guidance documents issued by NICE aimed to assess the policy impact of the sensitivity analysis and the PSA in particular. Qualitative interview data from NICE Technology Appraisal Committee members, collected as part of an earlier study, were also analysed to assess the value attached to the sensitivity analysis components of the economic analyses conducted for NICE. All forms of sensitivity analysis, notably both deterministic and probabilistic approaches, have their supporters and their detractors. Practice in relation to univariate sensitivity analysis is highly variable, with considerable lack of clarity in relation to the methods used and the basis of the ranges employed. In relation to PSA, there is a high level of variability in the form of distribution used for similar parameters, and the justification for such choices is rarely given. Virtually all analyses failed to consider correlations within the PSA, and this is an area of concern

The Centre for Reviews and Dissemination and the Centre for Health Economics at the University of York were commissioned to act as the evidence review group (ERG). This article presents a summary of the manufacturer's submission, the ERG report and the subsequent development of NICE guidance for the use of dabigatran within the UK National Health Service. Dabigatran was granted marketing authorisation by the European Medicines Agency for a sequential dosing regimen (DBG sequential), in which patients under 80 years are treated with dabigatran 150 mg twice daily (DBG150) and patients 80 years and over are given dabigatran 110 mg twice daily (DBG110). NICE decisions are bound by the marketing authorisation; therefore, the decision problem faced by the committee was whether the DBG sequential regimen was effective and cost-effective compared with warfarin or aspirin for patients with non-valvular AF and one or more risk factors. The RE-LY trial, a large multi-centre non-inferiority randomised clinical trial, was the primary source of clinical evidence. DBG150 was shown to be non-inferior, and subsequently superior to warfarin, for the primary outcome of all stroke/systemic embolism. DBG110 was found to be non-inferior to warfarin. Results were presented for a post hoc subgroup analysis for patients under and over 80 years of age, where DBG110 showed a statistically significant reduction of haemorrhagic stroke and intracranial haemorrhage in comparison to warfarin in patients over 80 years of age. This post hoc subgroup analysis by age was the basis for the licensed DBG sequential regimen

    Full Text Available Introduction. The National Institute for Health and Clinical Excellence (NICE guidance recommends that dyspeptic patients are tested for Helicobacter pylori using a urea breath test, stool antigen test, or serology. Antibiotic resistance in H. pylori is globally increasing, but treatment in England is rarely guided by susceptibility testing or surveillance. Aims. To determine compliance of microbiology laboratories in England with NICE guidance and whether laboratories perform culture and antibiotic susceptibility testing (AST. Methods. In 2015, 170 accredited English microbiology laboratories were surveyed, by email. Results. 121/170 (71% laboratories responded; 96% provided H. pylori testing (78% on site. 94% provided H. pylori diagnosis using stool antigen; only four provided serology as their noninvasive test; 3/4 of these encouraged urea breath tests in their acute trusts. Only 22/94 (23% of the laboratories performed H. pylori cultures from gastric biopsies on site; 9/22 performed AST, but the vast majority processed less than one specimen/week. Conclusions. Only five laboratories in England do not comply with NICE guidance; these will need the guidance reinforced. National surveillance needs to be implemented; culture-based AST would need to be centralised. Moving forward, detection of resistance in H. pylori from stool specimens using molecular methods (PCR needs to be explored.

  10. Iceless Icy Moons: Is the Nice Model In Trouble?

    Nimmo and Korycansky (2012; henceforth NK12) stated that if the outer Solar System underwent a Late Heavy Bombardment (LHB) in the Nice model, the mass striking the icy satellites at speeds up to tens of km/s would have vaporized so much ice that moons such as Mimas, Enceladus, and Miranda would have been devolatilized. NK12's possible explanations of this apparent discrepancy with observations include (1) the mass influx was a factor of 10 less than that in the Nice model; (2) the mass distribution of the impactors was top-heavy, so that luck might have saved some of the moons from suffering large, vapor-removing impacts; or (3) the inner moons formed after the LHB. NK12 calculated the mass influx onto the satellites from the lunar impact rate estimated by Gomes et al. (2005) and scaling factors calculated by Zahnle et al. (1998, 2003; also see Barr and Canup 2010). Production of vapor in hypervelocity impacts is calculated from Kraus et al. (2011). Our preliminary results show that there is about an order-of-magnitude uncertainty in the mass striking the satellites during the LHB, with NK12's estimate at the upper end of the range. We will discuss how the mass influx depends on the velocity and mass distributions of the impactors. The Nice model lives.

    There has been an increasing interest in the role of fermentable oligo-, di-, and monosaccharides and polyols (FODMAPs) in irritable bowel syndrome (IBS). We report results from the first randomized controlled trial of the low FODMAP diet in US adults with IBS and diarrhea (IBS-D). The objectives were to compare the efficacy of the low FODMAP diet vs. a diet based upon modified National Institute for Health and Care Excellence guidelines (mNICE) on overall and individual symptoms in IBS-D patients. This was a single-center, randomized-controlled trial of adult patients with IBS-D (Rome III) which compared 2 diet interventions. After a 2-week screening period, eligible patients were randomized to a low FODMAP or mNICE diet for 4 weeks. The primary end point was the proportion of patients reporting adequate relief of IBS-D symptoms ≥50% of intervention weeks 3-4. Secondary outcomes included a composite end point which required response in both abdominal pain (≥30% reduction in mean daily pain score compared with baseline) and stool consistency (decrease in mean daily Bristol Stool Form of ≥1 compared with baseline), abdominal pain and stool consistency responders, and other key individual IBS symptoms assessed using daily questionnaires. After screening, 92 subjects (65 women, median age 42.6 years) were randomized. Eighty-four patients completed the study (45 low FODMAP, 39 mNICE). Baseline demographics, symptom severity, and nutrient intake were similar between groups. Fifty-two percent of the low FODMAP vs. 41% of the mNICE group reported adequate relief of their IBS-D symptoms (P=0.31). Though there was no significant difference in the proportion of composite end point responders (P=0.13), the low FODMAP diet resulted in a higher proportion of abdominal pain responders compared with the mNICE group (51% vs. 23%, P=0.008). Compared with baseline scores, the low FODMAP diet led to greater reductions in average daily scores of abdominal pain, bloating

    Full Text Available In Nice Work, David Lodge appropriates the model of the « condition-of-England novel » which he transposes into the 1980s. More than a mere transposition, Nice Work turns out to be an open rewriting of the Victorian novels quoted in epigraphs since the text, with its comical aspect and its auto-reflexive dimension, distances itself from realism. Far from being innocent, this rewriting considers critically the Thatcher era as well as contemporary literary theory and gives a discerning homage to Victorian novels.

  14. Atrial fibrillation in a primary care population: how close to NICE guidelines are we?

    LENUS (Irish Health Repository)

    Loo, Bryan

    2009-06-01

    The National Institute for Health and Clinical Excellence (NICE) guidelines for the management of atrial fibrillation were published in June 2006. It was anticipated that they would potentially lead to increased demand for echocardiography (ECHO), increased access to secondary care services (for example for cardioversion), and require additional resources for monitoring anticoagulation. A primary care survey was therefore initiated in South Devon, in advance of publication of the guidelines as a snapshot of existing practice, to determine any additional resources and education required to meet the new standards. The main aim was to determine what proportion of patients were managed exclusively in primary care, how frequently patients were investigated by ECHO and whether anticoagulation was being appropriately targeted at patients at high risk of thromboembolic events.

    As part of its single technology appraisal process, the National Institute for Health and Care Excellence (NICE) invited the company that manufactures ponatinib (Inclusig ® ; Incyte Corporation) to submit evidence for the clinical and cost effectiveness for previously treated chronic myeloid leukaemia (CML) and Philadelphia-chromosome-positive acute lymphoblastic leukaemia (Ph+ ALL). This paper focusses on the three phases of CML: the chronic phase (CP), the accelerated phase (AP) and the blast crisis phase (BP). The School of Health and Related Research Technology Appraisal Group at the University of Sheffield was commissioned to act as the independent Evidence Review Group (ERG). This article presents the critical review of the company's submission by the ERG and the outcome of the NICE guidance. Clinical evidence for ponatinib was derived from a phase II, industry-sponsored, single-arm, open-label, multicentre, non-comparative study. Despite the limited evidence and potential for biases, this study demonstrated that ponatinib was likely to be an effective treatment (in terms of major cytogenetic response and major haematological response) with an acceptable safety profile for patients with CML. Given the absence of any head-to-head studies comparing ponatinib with other relevant comparators, the company undertook a matching-adjusted indirect comparison (MAIC) of ponatinib with bosutinib. The approach was only used for patients with CP-CML because comprehensive data were not available for the AP- or BP-CML groups to allow the matching technique to be used. Despite the uncertainty about the MAIC approach, ponatinib was considered likely to offer advantages over bosutinib in the third-line setting, particularly for complete cytogenetic response. The company developed two health economic models to assess the cost effectiveness of ponatinib for the treatment of patients in CP-CML or in advanced CML (AP- or BP-CML, which were modelled separately). The company did

    This paper describes NICeSim, an open-source simulator that uses machine learning (ML) techniques to aid health professionals to better understand the treatment and prognosis of premature newborns. The application was developed and tested using data collected in a Brazilian hospital. The available data were used to feed an ML pipeline that was designed to create a simulator capable of predicting the outcome (death probability) for newborns admitted to neonatal intensive care units. However, unlike previous scoring systems, our computational tool is not intended to be used at the patients bedside, although it is possible. Our primary goal is to deliver a computational system to aid medical research in understanding the correlation of key variables with the studied outcome so that new standards can be established for future clinical decisions. In the implemented simulation environment, the values of key attributes can be changed using a user-friendly interface, where the impact of each change on the outcome is immediately reported, allowing a quantitative analysis, in addition to a qualitative investigation, and delivering a totally interactive computational tool that facilitates hypothesis construction and testing. Our statistical experiments showed that the resulting model for death prediction could achieve an accuracy of 86.7% and an area under the receiver operating characteristic curve of 0.84 for the positive class. Using this model, three physicians and a neonatal nutritionist performed simulations with key variables correlated with chance of death. The results indicated important tendencies for the effect of each variable and the combination of variables on prognosis. We could also observe values of gestational age and birth weight for which a low Apgar score and the occurrence of respiratory distress syndrome (RDS) could be less or more severe. For instance, we have noticed that for a newborn with 2000 g or more the occurrence of RDS is far less problematic

    Noise-immune cavity-enhanced optical heterodyne molecular spectroscopy (NICE-OHMS) is a powerful technique for detection of molecular compounds in gas phase that is based on a combination of two important concepts: frequency modulation spectroscopy (FMS) for reduction of noise, and cavity enhancement, for prolongation of the interaction length between the light and the sample. Due to its unique properties, it has demonstrated unparalleled detection sensitivity when it comes to detection of molecular constituents in the gas phase. However, despite these, it has so far not been used for detection of atoms, i.e. for elemental analysis. The present work presents an assessment of the expected performance of Doppler-broadened (Db) NICE-OHMS for analytical atomic spectrometry, then referred to as noise-immune cavity-enhanced analytical atomic spectrometry (NICE-AAS). After a description of the basic principles of Db-NICE-OHMS, the modulation and detection conditions for optimum performance are identified. Based on a previous demonstrated detection sensitivity of Db-NICE-OHMS of 5 × 10- 12 cm- 1 Hz- 1/2 (corresponding to a single-pass absorbance of 7 × 10- 11 over 10 s), the expected limits of detection (LODs) of Hg and Na by NICE-AAS are estimated. Hg is assumed to be detected in gas phase directly while Na is considered to be atomized in a graphite furnace (GF) prior to detection. It is shown that in the absence of spectral interferences, contaminated sample compartments, and optical saturation, it should be feasible to detect Hg down to 10 zg/cm3 (10 fg/m3 or 10- 5 ng/m3), which corresponds to 25 atoms/cm3, and Na down to 0.5 zg (zg = zeptogram = 10- 21 g), representing 50 zg/mL (parts-per-sextillion, pps, 1:1021) in liquid solution (assuming a sample of 10 μL) or solely 15 atoms injected into the GF, respectively. These LODs are several orders of magnitude lower (better) than any previous laser-based absorption technique previously demonstrated under atmospheric

    Background Leg ulcers are a common cause of morbidity and disability and result in significant health and social care expenditure. The UK National Institute for Health and Care Excellence (NICE) Clinical Guideline (CG)168, published in July 2013, sought to improve care of patients with leg ulcers, recommending that patients with a break in the skin below the knee that had not healed within two weeks be referred to a specialist vascular service for diagnosis and management. Aim Determine the impact of CG168 on referrals to a leg ulcer service. Methods Patients referred with leg ulceration during an 18-month period prior to CG168 (January 2012-June 2013) and an 18-month period commencing six months after (January 2014-June 2015) publication of CG168 were compared. Results There was a two-fold increase in referrals (181 patients, 220 legs vs. 385 patients, 453 legs) but no change in mean age, gender or median-duration of ulcer at referral (16.6 vs. 16.2 weeks). Mean-time from referral to specialist appointment increased (4.8 vs. 6 weeks, p = 0.0001), as did legs with superficial venous insufficiency (SVI) (36% vs. 44%, p = 0.05). There was a trend towards more SVI endovenous interventions (32% vs. 39%, p = 0.271) with an increase in endothermal (2 vs. 32 legs, p = 0.001) but no change in sclerotherapy (24 vs. 51 legs) treatments. In both groups, 62% legs had compression. There was a reduction in legs treated conservatively with simple dressings (26% vs. 15%, p = 0.0006). Conclusions Since CG168, there has been a considerable increase in leg ulcer referrals. However, patients are still not referred until ulceration has been present for many months. Although many ulcers are multi-factorial and the mainstay of treatment remains compression, there has been an increase in SVI endovenous intervention. Further efforts are required to persuade community practitioners to refer patients earlier, to educate patients and encourage further investment in

    This research reports on the NICE Evidence search (ES) student champion scheme (SCS) first five years of activity (2011-2016) in terms of its impact on health care undergraduate students' information search skills and search confidence. A review of students' evaluation of the scheme was carried out to chart the changes in attitude towards NICE Evidence search as an online health care information source and to monitor students' approach to information seeking. This study is based on the results of questionnaires distributed to students before and after attending a training session on NICE Evidence search delivered by their own peers. The exercise was implemented in health related universities in England over a period of five consecutive academic years. (i) Students' search confidence improved considerably after the training; (ii) ES was perceived as being an increasingly useful resource of evidence based information for their studies; (iii) the training helped students develop discerning search skills and use evidence based information sources more consistently and critically. The NICE SCS improves confidence in approaching information tasks amongst health care undergraduate students. Future developments could involve offering the training at the onset of a course of study and adopting online delivery formats to expand its geographical reach. © 2018 Health Libraries Group.

    This paper examines audio-recorded data from meetings in which NHS managers decide whether to fund high-cost drugs for individual patients. It investigates the work of a Welsh individual patient commissioning (IPC) panel responsible for sanctioning the purchase of 'un-commissioned' treatments for exceptional cases. The case study presented highlights the changing rationales used for approving or denying a cancer drug, Tarceva, during a period when NICE first suggested it was not cost effective, but then changed its position in a final technology appraisal recommending use when the cost did not exceed that of an alternative product. Our data show how decisions taken in the shadow of NICE guidance remain complex and subject to local discretion. Guidance that takes time to prepare, is released in stages, and relates to particular disease stages, must be interpreted in the context of particular cases. The case-based IPC panel discourse stands in tension with the standardised population-based recommendations in guidance. Panel members, who based their decisions on the central notions of 'efficacy' and 'exceptionality', often struggled to apply NICE information on cost-effectiveness to their deliberations on efficacy (clinical effectiveness). The case study suggests that the complex nature of decision making makes standardization of outcomes very difficult to achieve, so that local professional judgement is likely to remain central to health care rationing at this level.

    As part of the UK National Institute for Health and Care Excellence (NICE) single technology appraisal process, independent evidence review groups (ERGs) critically appraise a company's submission relating to a specific technology and indication. To explore the type of additional exploratory analyses conducted by ERGs and their impact on the recommendations made by NICE. The 100 most recently completed single technology appraisals with published guidance were selected for inclusion. A content analysis of relevant documents was undertaken to identify and extract relevant data, and narrative synthesis was used to rationalize and present these data. The types of exploratory analysis conducted in relation to companies' models were fixing errors, addressing violations, addressing matters of judgment, and the provision of a new, ERG-preferred base case. Ninety-three of the 100 ERG reports contained at least one of these analyses. The most frequently reported type of analysis in these 93 ERG reports related to the category "Matters of judgment," which was reported in 83 reports (89%). At least one of the exploratory analyses conducted and reported by an ERG is mentioned in 97% of NICE appraisal consultation documents and 94% of NICE final appraisal determinations, and had a clear influence on recommendations in 72% of appraisal consultation documents and 47% of final appraisal determinations. These results suggest that the additional analyses undertaken by ERGs in the appraisal of company submissions are highly influential in the policy-making and decision-making process.

    Full Text Available Abstract Background Most patients contact their general practitioner (GP following presentation to an Emergency Department (ED after a self-harm incident, and strategies to help GPs manage these patients include efficient communication between services. The aim of this study was to assess the standard of documentation and communication to primary care from secondary care as recommended by the National Institute of Clinical Excellence (NICE guidelines on the short-term management of people who self-harm. Methods An audit of medical records (ED and Psychiatric on people aged 16 years and over who had presented to the ED following self-harm, benchmarked according to government guidelines, was performed. Data were collected over a 4-week period at a general teaching hospital. Results We collected data on 93 consecutive episodes of self-harm; 62% of episodes were communicated to primary care, 58% of these communications were within 24 h and most within 3 days. Patient identifying details and follow-up arrangements were specified in most cases. Communication via psychiatric staff was most detailed. ED clinicians provided few communications and were of limited content. Communication with the patient's GP was not made in half of those cases seen by a mental health specialist. Conclusion Government guidelines are only partially being met. Reliance on communication by ED staff would leave a substantial proportion of patients discharged from the ED with no or minimal communication to primary care. Psychiatric services need to improve the rate of communication to the patient's GP following assessment A national sample of National Health Service (NHS trusts would establish if this is a problem elsewhere.

    Neonatal jaundice is a very frequent condition that occurs in approximately 50-70% of term or near-term (>35 GA) babies in the 1st week of life. In some cases, a high bilirubin blood level can lead to kernicterus. There is no consensus for the management of neonatal jaundice and few countries have published national clinical practice guidelines for the management of neonatal jaundice. The aim of this study was to assess the quality of these guidelines. We conducted a systematic review of the literature for national clinical practice guidelines for the management of neonatal jaundice in term or near-term babies. Four independent reviewers assessed the quality of each guideline using the AGREE II evaluation. For each of the clinical practice guidelines, the management modalities were analyzed (screening, treatment, follow-up, etc.). Seven national clinical practice guidelines were found (South Africa, USA AAP, UK NICE, Canada, Norway, Switzerland, and Israel). The AGREE II score showed widespread variation regarding the quality of these national guidelines. There was no major difference between the guidelines concerning the clinical management of these babies. The NICE guideline is the most valuable guideline regarding the AGREE II score. NICE showed that, despite a strong and rigorous methodology, there is no evidenced-based recommended code of practice (RCP). Comparing RCPs, we found no major differences. The NICE guideline showed the best quality. The AGREE II instrument should be used as a framework when developing clinical practice guidelines to improve the quality of the future guideline. In France, a national guideline is needed for a more standardized management of neonatal jaundice. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    As part of its single technology appraisal (STA) process, the National Institute for Health and Care Excellence (NICE) invited the company that manufactures cabazitaxel (Jevtana ® , Sanofi, UK) to submit evidence for the clinical and cost effectiveness of cabazitaxel for treatment of patients with metastatic hormone-relapsed prostate cancer (mHRPC) previously treated with a docetaxel-containing regimen. The School of Health and Related Research Technology Appraisal Group at the University of Sheffield was commissioned to act as the independent Evidence Review Group (ERG). The ERG produced a critical review of the evidence for the clinical and cost effectiveness of the technology based upon the company's submission to NICE. Clinical evidence for cabazitaxel was derived from a multinational randomised open-label phase III trial (TROPIC) of cabazitaxel plus prednisone or prednisolone compared with mitoxantrone plus prednisone or prednisolone, which was assumed to represent best supportive care. The NICE final scope identified a further three comparators: abiraterone in combination with prednisone or prednisolone; enzalutamide; and radium-223 dichloride for the subgroup of people with bone metastasis only (no visceral metastasis). The company did not consider radium-223 dichloride to be a relevant comparator. Neither abiraterone nor enzalutamide has been directly compared in a trial with cabazitaxel. Instead, clinical evidence was synthesised within a network meta-analysis (NMA). Results from TROPIC showed that cabazitaxel was associated with a statistically significant improvement in both overall survival and progression-free survival compared with mitoxantrone. Results from a random-effects NMA, as conducted by the company and updated by the ERG, indicated that there was no statistically significant difference between the three active treatments for both overall survival and progression-free survival. Utility data were not collected as part of the TROPIC trial, and

    There is as yet no evidence on the feasibility of implementing recommendations from the National Institute of Health and Care Excellence (NICE) osteoarthritis (OA) guidelines in primary care, or of the effect these recommendations have on the condition. The primary aim of this study is to determine the clinical and cost effectiveness of a model OA consultation (MOAC), implementing the core recommendations from the NICE OA guidelines in primary care. Secondary aims are to investigate the impact, feasibility and acceptability of the MOAC intervention; to develop and evaluate a training package for management of OA by general practitioners (GPs) and practice nurses; test the feasibility of deriving 'quality markers' of OA management using a new consultation template and medical record review; and describe the uptake of core NICE OA recommendations in participants aged 45 years and over with joint pain. A mixed methods study with a nested cluster randomised controlled trial. This study was developed according to a defined theoretical framework (the Whole System Informing Self-management Engagement). An overarching model (the Normalisation Process Theory) will be employed to undertake a comprehensive 'whole-system' evaluation of the processes and outcomes of implementing the MOAC intervention. The primary outcome is general physical health (Short Form-12 Physical component score [PCS]) (Ware 1996). The impact, acceptability and feasibility of the MOAC intervention at practice level will be assessed by comparing intervention and control practices using a Quality Indicators template and medical record review. Impact and acceptability of the intervention for patients will be assessed via self-completed outcome measures and semi-structured interviews. The impact, acceptability and feasibility of the MOAC intervention and training for GPs and practice nurses will be evaluated using a variety of methods including questionnaires, semi-structured interviews, and observations

    2013-12-01

    As part of NASA's Minority University Research and Education Program (MUREP), the NASA Innovations in Climate Education (NICE) project at Langley Research Center has funded 71 climate education initiatives since 2008. The funded initiatives span across the nation and contribute to the development of a climate-literate public and the preparation of a climate-related STEM workforce through research experiences, professional development opportunities, development of data access and modeling tools, and educational opportunities in both K-12 and higher education. Each of the funded projects proposes and carries out its own evaluation plan, in collaboration with external or internal evaluation experts. Using this portfolio as an exemplar case, NICE has undertaken a systematic meta-evaluation of these plans, focused primarily on evaluation questions, approaches, and methods. This meta-evaluation study seeks to understand the range of evaluations represented in the NICE portfolio, including descriptive information (what evaluations, questions, designs, approaches, and methods are applied?) and questions of value (do these evaluations meet the needs of projects and their staff, and of NASA/NICE?). In the current climate, as federal funders of climate change and STEM education projects seek to better understand and incorporate evaluation into their decisions, evaluators and project leaders are also seeking to build robust understanding of program effectiveness. Meta-evaluations like this provide some baseline understanding of the current status quo and the kinds of evaluations carried out within such funding portfolios. These explorations are needed to understand the common ground between evaluative best practices, limited resources, and agencies' desires, capacity, and requirements. When NASA asks for evaluation of funded projects, what happens? Which questions are asked and answered, using which tools? To what extent do the evaluations meet the needs of projects and

    The National Institute for Health and Care Excellence (NICE) invited the company that manufactures ramucirumab (Cyramza ® , Eli Lilly and Company) to submit evidence of the clinical and cost effectiveness of the drug administered alone (monotherapy) or with paclitaxel (combination therapy) for treating adults with advanced gastric cancer or gastro-oesophageal junction (GC/GOJ) adenocarcinoma that were previously treated with chemotherapy, as part of the Institute's single technology appraisal (STA) process. Kleijnen Systematic Reviews Ltd (KSR), in collaboration with Erasmus University Rotterdam, was commissioned to act as the Evidence Review Group (ERG). This paper describes the company's submission, the ERG review, and NICE's subsequent decisions. Clinical effectiveness evidence for ramucirumab monotherapy (RAM), compared with best supportive care (BSC), was based on data from the REGARD trial. Clinical effectiveness evidence for ramucirumab combination therapy (RAM + PAC), compared with paclitaxel monotherapy (PAC), was based on data from the RAINBOW trial. In addition, the company undertook a network meta-analysis (NMA) to compare RAM + PAC with BSC and docetaxel. Cost-effectiveness evidence of monotherapy and combination therapy relied on partitioned survival, cost-utility models. The base-case incremental cost-effectiveness ratio (ICER) of the company was £188,640 (vs BSC) per quality-adjusted life-year (QALY) gained for monotherapy and £118,209 (vs BSC) per QALY gained for combination therapy. The ERG assessment indicated that the modelling structure represented the course of the disease; however, a few errors were identified and some of the input parameters were challenged. The ERG provided a new base case, with ICERs (vs BSC) of £188,100 (monotherapy) per QALY gained and £129,400 (combination therapy) per QALY gained and conducted additional exploratory analyses. The NICE Appraisal Committee (AC), considered the company's decision problem was in

A constant microseismicity and moderate size events (3.5 case of an offshore Mw 6.3 earthquake located at the place where two moderate size events (Mw 4.5) occurred recently and where a morphotectonic feature has been detected by a bathymetric survey. We used a stochastic empirical Green’s functions (EGFs) summation method to produce a population of realistic accelerograms on rock and soil sites in the city of Nice. The ground motion simulations are calibrated on a rock site with a set of ground motion prediction equations (GMPEs) in order to estimate a reasonable stress-drop ratio between the February 25th, 2001, Mw 4.5, event taken as an EGF and the target earthquake. Our results show that the combination of the GMPEs and EGF techniques is an interesting tool for site-specific strong ground motion estimation.

  17. HAS Should Not Be NICE: Rejecting Imaginary Worlds in the French Technology Assessment Guidelines

    Directory of Open Access Journals (Sweden)

    Paul C Langley

    2017-01-01

    Full Text Available Pricing decisions and access to pharmaceuticals should be evidence based. Unfortunately, the French guidelines for technology assessment, in their adoption of the National Institute for Health and Clinical Excellence (NICE reference case modeling standard ensure that this is not the case. Rather than requiring the submission of claims that are credible, evaluable and replicable, the Haute Autorité de Sante (HAS mandates the creation of imaginary worlds to support comparative effectiveness and cost-outcome claims. The purpose of this commentary is to make the case that HAS should reconsider this commitment to standards for health technology assessment that are more appropriately seen as pseudoscience. The recommendation is that HAS should put to one side mandating lifetime cost-per-quality adjusted life year (QALY or life years saved claims in favor of short-term claims that can be evaluated and reported to health system decision makers as part of a provisional assessment of new products as well as supporting ongoing disease area and therapeutic class reviews.   Type: Commentary

HTA processes for the Pharmaceutical Benefits Advisory Committee (PBAC in Australia, the Common Drug Review (CDR in Canada, and the National Institute for Health and Clinical Excellence (NICE in England and Wales are among the most established in the world. In this study, we performed nine in-depth case studies to assess whether different clinical evidence bases may have influenced listing recommendations made by PBAC, CDR, and NICE.Methods: Nine drugs were selected for which the three agencies had provided listing recommendations for the same indication between 2007 and 2010. We reviewed the evidence considered for each listing recommendation, identified the similarities and differences among the clinical evidence bases considered, and evaluated the extent to which different clinical evidence bases could have contributed to different decisions based on HTA body comments and public assessment of the evidence.Results: HTA agencies reached the same recommendation for reimbursement (recommended for listing for four drugs and different recommendations for five drugs. In all cases, each agency used different evidence bases in their recommendations. The agencies considered overlapping sets of clinical comparators and trials when evaluating the same drug. While PBAC and NICE considered indirect and/or mixed-treatment comparisons, CDR did not. In some cases, CDR and/or NICE excluded trials from review if the drug and/or the comparator were not administered according to the relevant marketing authorization.Conclusions: In the listing recommendations

  19. Societal views on NICE, cancer drugs fund and value-based pricing criteria for prioritising medicines: a cross-sectional survey of 4118 adults in Great Britain.

    2013-08-01

    The criteria used by the National Institute for Health and Clinical Excellence (NICE) for accepting higher incremental cost-effectiveness ratios for some medicines over others, and the recent introduction of the Cancer Drugs Fund (CDF) in England, are assumed to reflect societal preferences for National Health Service resource allocation. Robust empirical evidence to this effect is lacking. To explore societal preferences for these and other criteria, including those proposed for rewarding new medicines under the future value-based pricing (VBP) system, we conducted a choice-based experiment in 4118 UK adults via web-based surveys. Preferences were determined by asking respondents to allocate fixed funds between different patient and disease types reflecting nine specific prioritisation criteria. Respondents supported the criteria proposed under the VBP system (for severe diseases, address unmet needs, are innovative--provided they offered substantial health benefits, and have wider societal benefits) but did not support the end-of-life premium or the prioritisation of children or disadvantaged populations as specified by NICE, nor the special funding status for treatments of rare diseases, nor the CDF. Policies introduced on the basis of perceived--and not actual--societal values may lead to inappropriate resource allocation decisions with the potential for significant population health and economic consequences.

    1997-03-01

    The Department of Energy (DOE) has prepared a Programmatic Environmental Assessment (PEA), to assess the environment impacts associated with a joint DOE/EPA cost-sharing grant program named National Industrial Competitiveness through Energy Efficiency, Environment and Economics (NICE{sup 3}). The purpose of the NICE{sup 3} Program is to encourage waste minimization technology in industry by funding projects that develop activities and process improvements to conserve energy and reduce pollution. The proposed action would provide Federal financial assistance in the form of grants to industry in order to promote pollution prevention, energy efficiency, and cost competitiveness. Based on the analysis presented in the PEA, DOE has determined that the proposed action (providing NICE{sup 3} grants for projects which are consistent with the goals of the PPA and EPACT) does not constitute a major Federal action significantly affecting the quality of the human environment within the meaning of NEPA. Therefore, the preparation of an Environmental Impact Statement is not needed and the Department is issuing this Finding of No Significant Impact.

    As part of its Single Technology Appraisal process, the National Institute for Health and Care Excellence (NICE) invited the company that manufactures rivaroxaban (Xarelto, Bayer) to submit evidence of the clinical and cost effectiveness of rivaroxaban for the prevention of adverse outcomes in patients after the acute management of acute coronary syndrome (ACS). The School of Health and Related Research Technology Appraisal Group at the University of Sheffield was commissioned to act as the independent Evidence Review Group (ERG). The ERG produced a critical review of the evidence for the clinical and cost effectiveness of the technology, based upon the company's submission to NICE. The evidence was derived mainly from a randomised, double-blind, phase III, placebo-controlled trial of rivaroxaban (either 2.5 or 5 mg twice daily) in patients with recent ACS [unstable angina, non-ST segment elevation myocardial infarction (NSTEMI) or ST segment elevation myocardial infarction (STEMI)]. In addition, all patients received antiplatelet therapy [aspirin alone or aspirin and a thienopyridine either as clopidogrel (approximately 99 %) or ticlopidine (approximately 1 %) according to national or local guidelines]. The higher dose of rivaroxaban (5 mg twice daily) did not form part of the marketing authorisation. A post hoc subgroup analysis of the licensed patients who had ACS with elevated cardiac biomarkers (that is, patients with STEMI and NSTEMI) without prior stroke or transient ischaemic stroke showed that compared with standard care, the addition of rivaroxaban (2.5 mg twice daily) to existing antiplatelet therapy reduced the composite endpoint of cardiovascular mortality, myocardial infarction or stroke, but increased the risk of major bleeding and intracranial haemorrhage. However, there were a number of limitations in the evidence base that warrant caution in its interpretation. In particular, the evidence may be confounded because of the post hoc subgroup

    2018-04-06

    This study investigated how speaker certainty (a rational cue) and speaker benevolence (an emotional cue) influence children's willingness to learn words in a selective learning paradigm. In two experiments four- to six-year-olds learnt novel labels from two speakers and, after a week, their memory for these labels was reassessed. Results demonstrated that children retained the label-object pairings for at least a week. Furthermore, children preferred to learn from certain over uncertain speakers, but they had no significant preference for nice over nasty speakers. When the cues were combined, children followed certain speakers, even if they were nasty. However, children did prefer to learn from nice and certain speakers over nasty and certain speakers. These results suggest that rational cues regarding a speaker's linguistic competence trump emotional cues regarding a speaker's affective status in word learning. However, emotional cues were found to have a subtle influence on this process.

    Full Text Available Delirium is the most common problem in patients in intensive care units. Prevention of delirium is more important than treatment. The aim of this study is to determine the effect of the NICE-adjusted multifactorial intervention to prevent delirium in open heart surgery patients. Methods: This study is a quasi-experimental study on 88 patients (In each group, 44 patients undergoing open heart surgery in the intensive care unit of Imam Khomeini Hospital, Tehran. Subjects received usual care group, only the incidence of delirium were studied. So that patients in the two groups of second to fifth postoperative day, twice a day by the researcher, and CAM-ICU questionnaire were followed. After completion of the sampling in this group, in the intervention group also examined incidence of delirium was conducted in the same manner except that multifactorial interventions based on the intervention of NICE modified by the researcher on the second day to fifth implementation and intervention on each turn, their implementation was followed. As well as to check the quality of sleep and pain in the intervention group of CPOT and Pittsburgh Sleep assessment tools were used. Data analysis was done using the SPSS software, version 16. A T-test, a chi-square test, and a Fisher’s exact test were also carried out. Results: The incidence of delirium in the control group was 42.5%; and in the intervention group, it was 22.5%. The result showed the incidence of delirium in open heart surgery hospitalized patients after multifactorial intervention based on adjusted NICE guidelines has been significantly reduced. Conclusion: The NICE-adjusted multifactorial intervention guidelines for the prevention of delirium in cardiac surgery patients significantly reduced the incidence of delirium in these patients. So, using this method as an alternative comprehensive and reliable in preventing delirium in hospitalized patients in the ward heart surgery is recommended.

  8. EARLY DYNAMICAL EVOLUTION OF THE SOLAR SYSTEM: PINNING DOWN THE INITIAL CONDITIONS OF THE NICE MODEL

    International Nuclear Information System (INIS)

    Batygin, Konstantin; Brown, Michael E.

    2010-01-01

    In the recent years, the 'Nice' model of solar system formation has attained an unprecedented level of success in reproducing much of the observed orbital architecture of the solar system by evolving the planets to their current locations from a more compact configuration. Within the context of this model, the formation of the classical Kuiper Belt requires a phase during which the ice giants have a high eccentricity. An outstanding question of this model is the initial configuration from which the solar system started out. Recent work has shown that multi-resonant initial conditions can serve as good candidates, as they naturally prevent vigorous type-II migration. In this paper, we use analytical arguments, as well as self-consistent numerical N-body simulations to identify fully resonant initial conditions, whose dynamical evolution is characterized by an eccentric phase of the ice giants, as well as planetary scattering. We find a total of eight such initial conditions. Four of these primordial states are compatible with the canonical 'Nice' model, while the others imply slightly different evolutions. The results presented here should prove useful in further development of a comprehensive model for solar system formation.

    This article presents the results of a tentative application of Solid Phase Micro Extraction (SPME) to the analysis of BTEX (benzene, toluene, ethyl-benzene and xylenes) at the μg/m 3 level in indoor and outdoor air. The salient features of the method validation are reported. Sampling by QUALITAIR using Radiello passive samplers, was carried out from 2001 to 2004 in the city of Nice and its airport. Urban traffic impact was proved, but a link between BTX concentrations and the variations of airport activities was not clearly established. During the same period, several samplings were performed using SPME. Taking into account the short (30 minutes) sampling time, rapid changes of BTEX concentrations were evidenced, as for example the start of airplane engines. As field studies have shown, SPME technique appears as a method of choice for fast qualitative analysis and quantitative determination of Volatile Organic Compounds (VOC). The small dimensions of the SPME sampling system and the short sampling time let envisage its utilisation for the rapid diagnostic and the monitoring of indoor air quality. (author)

Model performance indices of calibration accuracy, discriminative and explanatory performance, including net reclassification index (NRI) and integrated discrimination improvement. Of 495 263 index patients hospitalised with AMI, there were 53 196 ST elevation myocardial infarction and 83 888 non-ST elevation myocardial infarction (NSTEMI) (27.7%) cases with complete data for all AMG variables. For AMI, AMG calibration was better than MG calibration (Hosmer-Lemeshow goodness of fit test: p=0.33 vs pModel performance was reduced in patients with NSTEMI, chronic heart failure, chronic renal failure and in patients aged ≥85 years. The AMG and MG risk scores, utilised by NICE, demonstrated good performance across a range of indices using MINAP data, but performed less well in higher risk subgroups. Although indices were better for AMG, its application may be constrained by missing predictors.

    We conducted a systematic review of clinical guidelines (CGs) to examine the methodological approaches of quality indicator derivation in CGs, the frequency of quality indicators to check CG recommendations in routine care, and clinimetric properties of quality indicators. We analyzed the publicly available CG databases of the Association of the Scientific Medical Societies in Germany (AWMF) and National Institute for Health and Care Excellence (NICE). Data on the methodology of subsequent quality indicator derivation, the content and definition of recommended quality indicators, and clinimetric properties of measurement instruments were extracted. In Germany, no explicit methodological guidance exists, but 3 different approaches are used. For NICE, a general approach is used for the derivation of quality indicators out of quality standards. Quality indicators were defined in 34 out of 87 CGs (39%) in Germany and for 58 out of 133 (43%) NICE CGs. Statements regarding measurement properties of instruments for quality indicator assessment were missing in German and NICE documents. Thirteen pairs of CGs (32%) have associated quality indicators. Thirty-four quality indicators refer to the same aspect of the quality of care, which corresponds to 27% of the German and 7% of NICE quality indicators. The development of a standardized and internationally accepted methodology for the derivation of quality indicators relevant to CGs is needed to measure and compare quality of care in health care systems.

    Objective:To differentiate between Ambler class A, B and D of carbapenemase-producing Enterobacteriaceae by using simple phenotypic methods that can be carried out in the laboratory without requiring any specialised techniques. Study Design:Cross-sectional study. Place and Duration of Study:Microbiology Department, Army Medical College, NUST, Islamabad, from November 2015 to November 2016. Methodology: Clinical specimens were subjected to identification of Enterobacteriaceae by colony morphology and API 20 E. Carbapenem resistance was detected by applying meropenem disc (10 mu g) by disc diffusion method according to CLSI (Clinical Laboratory Standard Institute) criteria. Carbapenemase production among Enterobacteriaceaewas detected by Modified Hodge test. Phenotypic methods, Phenylboronic acid (for Class A KPC producing Enterobacteriaceae) and EDTA inhibition tests (for Class B MBL producing Entrobacteriaceae) were applied. Presence of OXA 48 was detected by phenotypic method using imipenem 10 mu g, EDTA and PBA discs. Antibiotic susceptibility was determined by Kirby-Bauer disc diffusion method. Results:Forty-three out of 45 (95.45%) were carbapenemase producers. Thirty-eight out of 43 (88.3%) were KPC producers and 4 out of 43 (11.62%) were MBL producers. All KPC producers were Klebsiella pneumoniae. Among five MBL producers, one each (20%) was Enterobacter cloacae and Escherichia coli and 3 (60%) were Klebsiella pneumoniae. All MBL producers were resistant to aztreonam and amoxicillin/clavulanate. Two of the KPC producing Klebsiella pneumoniaewere pan-drug resistant (resistant to colistin and tigecycline). Two were non-carbapenemase producers. Conclusion:Enterobacteriaceaestrains producing KPC-type carbapenemase were the most prevalent (88.3%) in the studied healthcare setup. (author)

    The National Institute for Health and Care Excellence (NICE) invited the manufacturer (Shire Pharmaceuticals) of pegylated liposomal irinotecan hydrochloride trihydrate (liposomal irinotecan) to submit clinical and cost-effectiveness evidence for its use in combination with 5-fluorouracil (5-FU) and folic acid/leucovorin (LV) for treating patients with pancreatic cancer following prior treatment with gemcitabine as part of the institute's Single Technology Appraisal process. The Liverpool Reviews and Implementation Group at the University of Liverpool was commissioned to act as the Evidence Review Group (ERG). This article presents a summary of the company's evidence, the ERG review and the resulting NICE guidance (TA440), issued on 26 April 2017. Clinical evidence for liposomal irinotecan + 5-FU/LV versus 5-FU/LV was derived from 236 patients with metastatic pancreatic cancer in the multinational, open-label, randomised controlled NAPOLI-1 trial. Results from analyses of progression-free survival and overall survival showed statistically significant improvements for patients treated with liposomal irinotecan + 5-FU/LV compared with those treated with 5-FU/LV. However, 5-FU/LV alone is rarely used in National Health Service clinical practice for patients with metastatic pancreatic cancer previously treated with gemcitabine. The company, ERG and Appraisal Committee (AC) all agreed that oxaliplatin + 5-FU/LV is the most commonly used treatment. Oxaliplatin + 5-FU/LV was compared with 5-FU/LV in two trials identified by the company. However, the company and the ERG both considered attempts to compare the efficacy of liposomal irinotecan + 5-FU/LV with oxaliplatin + 5-FU/LV to be methodologically flawed; not only was there heterogeneity between trials and their populations but also the proportional hazards assumption required to conduct a robust indirect treatment comparison (ITC) was violated. Nonetheless, data derived from an ITC were used to inform the

    Atmospheric measurements were made over Arctic sea ice north of Svalbard from winter to early summer (January-June) 2015 during the Norwegian Young Sea Ice (N-ICE2015) expedition. These measurements, which are available publicly, represent a comprehensive meteorological data set covering the seasonal transition in the Arctic Basin over the new, thinner sea ice regime. Winter was characterized by a succession of storms that produced short-lived (less than 48 h) temperature increases of 20 to 30 K at the surface. These storms were driven by the hemispheric scale circulation pattern with a large meridional component of the polar jet stream steering North Atlantic storms into the high Arctic. Nonstorm periods during winter were characterized by strong surface temperature inversions due to strong radiative cooling ("radiatively clear state"). The strength and depth of these inversions were similar to those during the Surface Heat Budget of the Arctic Ocean (SHEBA) campaign. In contrast, atmospheric profiles during the "opaquely cloudy state" were different to those from SHEBA due to differences in the synoptic conditions and location within the ice pack. Storm events observed during spring/summer were the result of synoptic systems located in the Barents Sea and the Arctic Basin rather than passing directly over N-ICE2015. These synoptic systems were driven by a large-scale circulation pattern typical of recent years, with an Arctic Dipole pattern developing during June. Surface temperatures became near-constant 0°C on 1 June marking the beginning of summer. Atmospheric profiles during the spring and early summer show persistent lifted temperature and moisture inversions that are indicative of clouds and cloud processes.

  16. Clinical and cardiovascular alterations produced by scorpion envenomation in dogs

    Full Text Available Scorpionism is a common problem that occurs in tropical and subtropical countries and assumes great medical-sanitary importance due to its fatal effect on sensitive individuals, being able to lead children and aged people to death. The envenomation lethal potential is responsible for the serious cardiopulmonary alterations the scorpion toxin produces in its victims. The present research evaluated the effects of Tityus serrulatus venom on dogs, using two distinct doses: a dose that simulates natural envenomation (0.4 mg/total dose, and an experimental dose (0.25 mg/kg. General clinical signs were observed at different moments after envenomation, and specific data related to the cardiopulmonary system were evaluated by systemic arterial pressure measurement, CK-MB enzymatic activity dosage, and radiographic, electrocardiographic and echocardiographic examinations. Results demonstrated that the scorpion venom, in experimental doses, was able to cause acute and reversible cardiac injury in few days, and, in the dose that simulated natural accident, it produced clinical signs of light envenomation, such as local pain, hyperesthesia, sialorrhea, vomiting, diarrhea, sneeze and prostration.

  17. Clinical laboratory detection of carbapenem-resistant and carbapenemase-producing Enterobacteriaceae.

    2016-08-01

    Carbapenemases, enzymes that hydrolyze carbapenem-class antimicrobials, pose serious clinical and diagnostic challenges, including their recent rapid spread among members of the Enterobacteriaceae, a family with no inherent carbapenem resistance. Currently there is no one-size-fits-all method for detecting carbapenem-resistant Enterobacteriaceae (CRE) in the laboratory, nor how to differentiate carbapenemase-producers (CP) from isolates that are carbapenem-resistant via other or combined mechanisms. This article reviews definitions for CRE and CP-CRE, and discusses current phenotypic and molecular methods available to the clinical laboratory for the detection of both CP and non-CP CRE. Expert commentary: Routine evaluation of carbapenem resistance mechanism by the routine clinical laboratory are not necessary for patient care, as clinical breakpoints best predict response. However, evaluation for carbapenemase is integral to infection control efforts, and laboratories should have the capacity to do such testing, either in house or by submitting isolates to a reference laboratory.

  18. How did the ball of rock we live on get so nice?

    Armstrong, K.

    2017-12-01

    We want to understand how the big ball of rock, water, and air we live on got to be as nice as it is. Some of the things that made our world so nice are what it's made of, and what happened to those things after they were all put together. When our home ball of rock was little, it got bigger by grabbing some of the other stuff that was close by in space. So our world is made of all that space stuff, which was rocks, and that stuff that turns red if you let it get wet. Most of that red stuff is deep down in the middle of the world, covered up by a lot of rocks. But there is a lot of it inside the rocks, too. That red stuff does a lot of cool stuff when it touches other things, especially the kind of air we like to breathe- that is what makes it turn red. Just one very tiny piece of the red stuff can join up with the breathing air in different ways: it can team up with none at all, or a little bit, or a lot, or even more. If we look at how much of the breathing air is teamed up with the red stuff inside the rocks, we can learn about how the rocks got there and what happened to them a long time ago. In the rocks that we can look at, there is more of the breathing air teamed up with the red stuff than we might have thought. We think that maybe that is because when more and more stuff tries to fit in the same small space, and gets pressed down, like it does deep down in our world, it can change in ways we do not expect. When our world was almost as big as it is now, it probably grabbed some space stuff that was almost as big as it was. The space stuff would have run into our world really hard, and that would have made everything really hot, hot enough to make all the rocks in the world move like water. We have an idea that maybe, when all the rocks on the world were really hot and moved around like water, deep down the red stuff and the breathing air might have got all pressed together very hard, so that more of the breathing air would team up with the red stuff than it

    As part of its single technology appraisal process, the National Institute for Health and Care Excellence invited the manufacturer (Eli Lilly) of baricitinib (BARI; Olumiant ® ; a Janus kinase inhibitor that is taken orally) to submit evidence of its clinical and cost effectiveness for the treatment of moderate to severe rheumatoid arthritis (RA) after the failure of disease-modifying antirheumatic drugs (DMARDs). The School of Health and Related Research Technology Appraisal Group at the University of Sheffield was commissioned to act as the independent Evidence Review Group (ERG). The ERG produced a detailed review of the evidence for the clinical and cost effectiveness of the technology, based on the company's submission (CS) to NICE. The clinical-effectiveness evidence in the CS for BARI was based predominantly on three randomised controlled trials comparing the efficacy of BARI against adalimumab or placebo, as well as one long-term extension study. The clinical-effectiveness review identified no head-to-head evidence on the efficacy of BARI against all the comparators within the scope. Therefore, the company performed network meta-analyses (NMAs) in two different populations: one in patients who had experienced an inadequate response to conventional DMARDs (cDMARD-IR), and the other in patients who had experienced an inadequate response to tumour necrosis factor inhibitors (TNFi-IR). The company's NMAs concluded BARI had comparable efficacy as the majority of its comparators in both populations. The company submitted a de novo discrete event simulation model that analysed the incremental cost-effectiveness of BARI versus its comparators for the treatment of RA from the perspective of the National Health Service (NHS) in four different populations: (1) cDMARD-IR patients with moderate RA, defined as a 28-Joint Disease Activity Score (DAS28) > 3.2 and no more than 5.1; (2) cDMARD-IR patients with severe RA (defined as a DAS28 > 5.1); (3) TNFi-IR patients

    The National Institute for Health and Care Excellence (NICE) invited Janssen, the company manufacturing abiraterone acetate (AA; tradename Zytiga ® ), to submit evidence for the clinical and cost effectiveness of AA in combination with prednisone/prednisolone (AAP) compared with watchful waiting (i.e. best supportive care [BSC]) for chemotherapy-naïve patients with metastatic castration-resistant prostate cancer (mCRPC). Kleijnen Systematic Reviews Ltd (KSR), in collaboration with Maastricht University Medical Center, was commissioned as the Evidence Review Group (ERG). This paper presents a summary of the company submission (CS), the ERG report, subsequent addenda, and the development of the NICE guidance for the use of this drug in England and Wales by the Appraisal Committee (AC). The ERG produced a critical review of the clinical and cost effectiveness of AAP based on the CS. An important question in this appraisal was, according to the ERG, whether AAP followed by docetaxel is more effective than BSC followed by docetaxel. In the COU-AA-302 trial, 239 of 546 (43.8 %) AAP patients and 304 of 542 (56.1 %) BSC patients received docetaxel as subsequent therapy, following AA or placebo. The results for this specific group of patients were not presented in the CS; therefore, the ERG asked the company to provide these data in the clarification letter; however, these data were presented as commercial-in-confidence and cannot therefore be reported here. The ERG's critical assessment of the company's economic evaluation highlighted a number of concerns, including (a) not using the intention-to-treat (ITT) population; (b) inconsistencies in estimating prediction equations; (c) not fully incorporating the impact of adverse events; (d) incorrectly incorporating the new patient access scheme (PAS); and (e) the assumption that AA non-compliance leads to recoverable drug costs. Although some of these issues were adjusted in the ERG base case, the ERG could not estimate

    Interest in searching for mutations in BRCA1 and BRCA2 is high. Knowledge regarding these genes and the advantages and limitations of genetic testing is limited. It is unknown whether increasing knowledge about breast cancer genetic testing alters interest in testing. Three hundred and seventy nine women (260 with a family history of breast cancer; 119 with breast cancer) from The Royal Marsden NHS Foundation Trust were randomised to receive or not receive written educational information on cancer genetics. A questionnaire was completed assessing interest in BRCA1 testing and knowledge on breast cancer genetics and screening. Actual uptake of BRCA1 testing is reported with a six year follow-up. Eighty nine percent of women at risk of breast cancer and 76% of women with breast cancer were interested in BRCA1 testing (P testing, the families of 66% of the at risk group and 13% of the women with breast cancer would be eligible for testing (probability of BRCA1 mutation >or=20%). Within six years of randomisation, genetic testing was actually undertaken on 12 women, only 10 of whom would now be eligible, on the NICE guidelines. There is strong interest in BRCA1 testing. Despite considerable ignorance of factors affecting the inheritance of breast cancer, education neither reduced nor increased interest to undergo testing. The NICE guidelines successfully triage those with a high breast cancer risk to be managed in cancer genetics clinics.

    As part of the development of the National Institute for Health and Care Excellence (NICE) Medical Technologies Guidance on Parafricta Bootees and Undergarments to reduce skin breakdown in people with, or at risk of, pressure ulcers, the manufacturer (APA Parafricta Ltd) submitted clinical and economic evidence, which was critically appraised by an External Assessment Centre (EAC) and subsequently used by the Medical Technologies Advisory Committee (MTAC) to develop recommendations for further research. The University of Birmingham and Brunel University, acting as a consortium, were commissioned to act as the EAC, independently appraising the submission. This article is an overview of the original evidence submitted, the EAC's findings and the final NICE guidance. Very little comparative evidence was submitted to demonstrate the effectiveness of Parafricta Bootees or Undergarments. The sponsor submitted a simple cost analysis to estimate the costs of using Parafricta in addition to current practice-in comparison with current practice alone-in hospital and community settings separately. The analysis took a National Health Service (NHS) perspective. The basis of the analysis was a previously published comparative study, which showed no statistical difference in average lengths of stay between patients who wore Parafricta Undergarments and Bootees, and those who did not. The economic model incorporated the costs of Parafricta but assumed shorter lengths of stay with Parafricta. The sponsor concluded that Parafricta was cost saving relative to the comparators. The EAC made amendments to the sponsor's analysis to correct for errors and to reflect alternative assumptions. Parafricta remained cost saving in most analyses, and the savings per prevalent case ranged from £757 in the hospital model to £3455 in the community model. All analyses were severely limited by the available data on effectiveness-in particular, a lack of good-quality comparative studies.

    BACKGROUND: The National Institute for Health and Clinical Excellence (NICE) guidelines recommend a timeline of 6 weeks from referral to neurology consultation and then 6 weeks to a diagnosis of multiple sclerosis (MS). OBJECTIVES: We audited the clinical management of all new outpatient referrals diagnosed with MS between January 2007 and May 2010. METHODS: We analysed the timelines from referral to first clinic visit, to MRI studies and lumbar puncture (LP) (if performed) and the overall interval from first visit to the time the diagnosis was given to the patient. RESULTS: Of the 119 diagnoses of MS\\/Clinically Isolated Syndrome (CIS), 93 (78%) were seen within 6 weeks of referral. MRI was performed before first visit in 61% and within 6 weeks in a further 27%. A lumbar puncture (LP) was performed in 83% of all patients and was done within 6 weeks in 78%. In total, 63 (53%) patients received their final diagnosis within 6 weeks of their first clinic visit, with 57 (48%) patients having their diagnosis delayed. The main rate-limiting steps were the availability of imaging and LP, and administrative issues. CONCLUSIONS: We conclude that, even with careful scheduling, it is difficult for a specialist service to obtain MRI scans and LP results so as to fulfil NICE guidelines within the optimal six-week period. An improved service would require MRI scans to be arranged before the first clinic visit in all patients with suspected MS.

    The United Kingdom's National Institute for Health and Care Excellence (NICE) recently published recommendations that support planned home birth for low-risk women. The American College of Obstetricians and Gynecologists (ACOG) remains wary of planned home birth, asserting that hospitals and birthing centers are the safest birth settings. Our objective was to examine opinions of obstetricians in Salt Lake City, Utah about home birth in the context of rising home birth rates and conflicting guidelines. Participants were recruited through online searches of Salt Lake City obstetricians and through snowball sampling. We conducted individual interviews exploring experiences with and attitudes toward planned home birth and the ACOG/NICE guidelines. Fifteen obstetricians who varied according to years of experience, location of medical training, sex, and subspecialty (resident, OB/GYN, maternal-fetal medicine specialist) were interviewed. Participants did not recommend home birth but supported a woman's right to choose her birth setting. Obstetrician opinions about planned home birth were shaped by misconceptions of home birth benefits, confusion surrounding the scope of care at home and among home birth providers, and negative transfer experiences. Participants were unfamiliar with the literature on planned home birth and/or viewed the evidence as unreliable. Support for ACOG guidelines was high, particularly in the context of the United States health care setting. Physician objectivity may be limited by biases against home birth, which stem from limited familiarity with published evidence, negative experiences with home-to-hospital transfers, and distrust of home birth providers in a health care system not designed to support home birth. © 2017 Wiley Periodicals, Inc.

    Financial relationships between organizations that produce clinical practice guidelines and biomedical companies are vulnerable to conflicts of interest. We sought to determine whether organizations that produce clinical practice guidelines have financial relationships with biomedical companies and whether there are associations between organizations' conflict of interest policies and recommendations and disclosures provided in guidelines. We conducted a cross-sectional survey and review of websites of 95 national/international medical organizations that produced 290 clinical practice guidelines published on the National Guideline Clearinghouse website from January 1 to December 31, 2012. Survey responses were available for 68% (65/95) of organizations (167/290 guidelines, 58%), and websites were reviewed for 100% (95/95) of organizations (290/290 guidelines, 100%). In all, 63% (60/95) of organizations producing clinical practice guidelines reported receiving funds from a biomedical company; 80% (76/95) of organizations reported having a policy for managing conflicts of interest. Disclosure statements (disclosing presence or absence of financial relationships with biomedical companies) were available in 65% (188/290) of clinical practice guidelines for direct funding sources to produce the guideline, 51% (147/290) for financial relationships of the guideline committee members, and 1% (4/290) for financial relationships of the organizations producing the guidelines. Among all guidelines, 6% (18/290) disclosed direct funding by biomedical companies, 40% (117/290) disclosed financial relationships between committee members and biomedical companies (38% of guideline committee members, 773/2,043), and 1% (4/290) disclosed financial relationships between the organizations producing the guidelines and biomedical companies. In the survey responses, 60 organizations reported the procedures that they included in their conflict of interest policies (158 guidelines

    Full Text Available Introduction. Infections due to extended spectrum β-lactamase producing Enterobacteriaceae are on the rise. They pose serious public health problems due to their resistance to large number of antibiotics. However, little is known about the genotypes of ESBL from Nepal. Therefore, the study presents results of phenotypic and molecular characterization of ESBL producing Escherichia coli and Klebsiella spp. isolated from various clinical specimens in a tertiary care teaching hospital of Nepal. Methods. A total of 172 Enterobacteriaceae clinical isolates recovered from various clinical specimens were analyzed for their antibiotic susceptibility test. Detection of ESBLs was carried out using combination disk test and multiplex PCR for their genotypes (CTX-M, SHV, and TEM. Results. Out of 172 clinical isolates, 70 (40.6% of them were found ESBL producers. The major source of ESBL producers was urinary tract samples and the highest ESBL production was observed in Escherichia coli (46.5%. Among ESBL genotypes, CTX-M (91.4% was most predominant, followed by TEM (65.7% and SHV (11.4% in both of the isolates. Conclusions. High level of drug resistance and ESBL production was observed among the clinical isolates. There is a need for longitudinal and nationwide surveillance for drug resistance in clinical isolates and antimicrobial stewardship is necessary to guide the appropriate and judicious antibiotic use.

    The wide dissemination of carbapenemase-producing Gram-negatives (CPGNs), including enterobacterial species and non-fermenters, has caused a public health crisis of global dimensions. These organisms cause serious infections in hospitalized patients, and are associated with increased mortality. Cross-transmission is common, and outbreaks may occur in healthcare facilities where the infection control practices are inadequate. CPGNs exhibit extensive drug-resistant phenotypes, complicate therapy, and limit treatment options. Systematic data on therapy are limited. However, regimens combining two or more active agents seem to be more efficacious than monotherapy in carbapenemase-producing Klebsiella pneumoniae infections. Strict infection control measures, including active surveillance for timely detection of colonized patients, separation of carriers from non-carriers, and contact precautions, are of utmost importance, and may be the only effective way of preventing the introduction and transmission of these bacteria in healthcare settings. © 2012 The Authors.

    patients had not responded to BCRi therapy, consistent with venetoclax's licensed indication. For PC, the company submission used data from the UK CLL Forum. The company's base-case analysis indicated that venetoclax was clinically effective, but the resulting incremental cost-effectiveness ratios (ICERs) for del(17p)/TP53 (£39,940/quality-adjusted life-year [QALY] gained) and non-del(17p)/TP53 (£47,370/QALY gained) patients were well above the NICE threshold of £20,000-30,000/QALY. The ERG identified two errors in the implementation of the company's parametric models-one related to the implementation of HRs, and the other to the derivation of the Weibull shape parameters obtained from the Gilead idelalisib submission. The ERG made plausible adjustments to the company's base-case and corrected errors, resulting in a reduced estimate of the cost effectiveness of venetoclax in non-del(17p)/TP53 and del(17p)/TP53 indications; in the ERG's preferred base case, using post-progression survival of patients in the idelalisib arm of study 116 as the BSC comparator, deterministic ICERs were higher than the company's base-case for both indications: £57,476/QALY gained for del(17p)/TP53 and £77,779/QALY gained for non-del(17p)/TP53. The NICE Appraisal Committee's preliminary recommendation was that venetoclax used within its licensed indication should not be recommended for use in the National Health Service (NHS). In response to the preliminary recommendation, the company submitted new analyses; however, at a subsequent appraisal committee meeting, the original recommendation was upheld and the committee concluded there were large uncertainties around the clinical effectiveness of venetoclax and BSC, and that under the committee's preferred assumptions, the ICERs were higher than those generally considered cost effective, even when end-of-life criteria were taken into account. The company submitted further evidence, and the final guidance recommended venetoclax for use with the

    The N-ICE2015 cruise, led by the Norwegian Polar Institute, was a drift experiment with the research vessel R/V Lance from January to June 2015, where the ship started the drift North of Svalbard at 83°14.45' N, 21°31.41' E. The drift was repeated as soon as the vessel drifted free. Altogether, 4 ice stations where installed and the complex ocean-sea ice-atmosphere system was studied with an interdisciplinary Approach. During the N-ICE2015 cruise, extensive ice thickness and snow depth measurements were performed during both, winter and summer conditions. Total ice and snow thickness was measured with ground-based and airborne electromagnetic instruments; snow depth was measured with a GPS snow depth probe. Additionally, ice mass balance and snow buoys were deployed. Snow and ice thickness measurements were performed on repeated transects to quantify the ice growth or loss as well as the snow accumulation and melt rate. Additionally, we collected independent values on surveys to determine the general ice thickness distribution. Average snow depths of 32 cm on first year ice, and 52 cm on multi-year ice were measured in January, the mean snow depth on all ice types even increased until end of March to 49 cm. The average total ice and snow thickness in winter conditions was 1.92 m. During winter we found a small growth rate on multi-year ice of about 15 cm in 2 months, due to above-average snow depths and some extraordinary storm events that came along with mild temperatures. In contrast thereto, we also were able to study new ice formation and thin ice on newly formed leads. In summer conditions an enormous melt rate, mainly driven by a warm Atlantic water inflow in the marginal ice zone, was observed during two ice stations with melt rates of up to 20 cm per 24 hours. To reinforce the local measurements around the ship and to confirm their significance on a larger scale, we compare them to airborne thickness measurements and classified SAR-satellite scenes. The

    Objective: To determine the susceptibility pattern of extended spectrum beta-lactamase (ESBL) producing Gram negative isolates from various clinical specimens. Study Design: Descriptive study. Place and Duration of Study: Microbiology Department, Armed Forces Institute of Pathology, Rawalpindi, from January 2008 to January 2009. Methodology: A total of 308 ESBL producing isolates from various clinical specimens sent to AFIP for culture and sensitivity were identified using standard microbiological techniques and tested for antimicrobial susceptibility. At the same time screening for ESBL production was also done. ESBL production was confirmed by combination disc synergy method. The susceptibility pattern of isolates was then recorded in frequency percentages. Results: Out of the 308 ESBL producing isolates more than 99% were susceptible to carbapenems, 84% to tazobactam/ piperacillin, 81% to sulbactam/cefoperazone, 12% to fluoroquinolones, 13% to cotrimoxazole, 59% to amikacin and 18% to gentamicin. Among the urinary isolates 49% were susceptible to Nitrofurontoin and only 5% to Pipemidic acid. Conclusion: Antibiotic choices in case of ESBL producing isolates are limited and at present only carbapenems can be regarded as treatment of choice. As empirical agents, beta-lactam/beta lactamase inhibitor combinations should be used cautiously for serious infections. Fluoroquinolones showed very poor efficacy. Amikacin can be used alternatively in such cases. Nitrofurantoin is still a good oral agent for treating UTI. (author)

  17. MICE or NICE? An economic evaluation of clinical decision rules in the diagnosis of heart failure in primary care.

    Detection and treatment of heart failure (HF) can improve quality of life and reduce premature mortality. However, symptoms such as breathlessness are common in primary care, have a variety of causes and not all patients require cardiac imaging. In systems where healthcare resources are limited, ensuring those patients who are likely to have HF undergo appropriate and timely investigation is vital. A decision tree was developed to assess the cost-effectiveness of using the MICE (Male, Infarction, Crepitations, Edema) decision rule compared to other diagnostic strategies to identify HF patients presenting to primary care. Data from REFER (REFer for EchocaRdiogram), a HF diagnostic accuracy study, was used to determine which patients received the correct diagnosis decision. The model adopted a UK National Health Service (NHS) perspective. The current recommended National Institute for Health and Care Excellence (NICE) guidelines for identifying patients with HF was the most cost-effective option with a cost of £4400 per quality adjusted life year (QALY) gained compared to a "do nothing" strategy. That is, patients presenting with symptoms suggestive of HF should be referred straight for echocardiography if they had a history of myocardial infarction or if their NT-proBNP level was ≥400pg/ml. The MICE rule was more expensive and less effective than the other comparators. Base-case results were robust to sensitivity analyses. This represents the first cost-utility analysis comparing HF diagnostic strategies for symptomatic patients. Current guidelines in England were the most cost-effective option for identifying patients for confirmatory HF diagnosis. The low number of HF with Reduced Ejection Fraction patients (12%) in the REFER patient population limited the benefits of early detection. Copyright © 2017 The Authors. Published by Elsevier B.V.

    To review the financial aspects of implementing the latest NICE guideline for neck of femur fracture (CG124), which recommends offering Total Hip Replacement (THR) as an alternative to hemiarthroplasty (HA) for patients, who are independently mobile before injury, not cognitively impaired and well enough to tolerate the operation. Between April 2011 and April 2013 data collected from our Hip Fracture database (NHFD) showed that by following the latest NICE guideline (CG124), out of 840 patients, 176 patients (21%) should be considered for THR rather than HA. Individual procedure costs were calculated by considering cost of implants and consumables (extracted from providers' published catalogues) added to the cost of running operating theatre for each operation. We then used the national tariff for each procedure using relevant HRG codes to calculate the total cost and the income to the Trust. Our data indicated that by implementing the latest NICE guideline (CG124), 37.1% of patients with intra-capsular fracture neck of femur (IC-NOF fracture) would be eligible for THR rather than HA. Although performing cemented THR was the more expensive procedure, our calculation shows that despite increased cost of performing the operation, Trusts can increase their net income by £300-600 (depending on their market force factor) per patient using correct HRG coding and National Tariff. Utilising 2012-13 National Tariff, performing a cemented THR instead of a HA for patients with IC-NOF fracture, as recommended by the latest NICE guideline (CG124) can increase the Trust's revenue per patient in a predictable way. This practice not only results in potentially better patient outcomes but also can increase financial reward and potential for reinvestment in all hip fracture units in the UK.

    Despite a lack of service provision for people with osteoarthritis (OA), each year 1 in 5 of the general population consults a GP about a musculoskeletal condition such as OA. Consequently this may provide an opportunity for practice nurses to take an active role in helping patients manage their condition. A nurse led clinic for supporting patients with OA was developed for the MOSAICS study investigating how to implement the NICE 2014 OA Guideline core recommendations. This paper has two main objectives, firstly to provide an overview of the nurse-led OA clinic, and secondly to describe the development, key learning objectives, content and impact of the training to support its delivery. A training programme was developed and delivered to provide practice nurses with the knowledge and skill set needed to run the nurse-led OA clinic. The impact of the training programme on knowledge, confidence and OA management was evaluated using case report forms and pre and post training questionnaires. The pre-training questionnaire identified a gap between what practice nurses feel they can do and what they should be doing in line with NICE OA guidelines. Evaluation of the training suggests that it enabled practice nurses to feel more knowledgeable and confident in supporting patients to manage their OA and this was reflected in the clinical management patients received in the nurse-led OA clinics. A significant gap between what is recommended and what practice nurses feel they can currently provide in terms of OA management was evident. The development of a nurse training programme goes some way to develop a system in primary care for delivering the core recommendations by NICE. The cluster trial linked to this training was conducted from May 2012 through February 2014 by the Arthritis Research UK Primary Care Centre, Keele University, UK (Trial registration number ISRCTN06984617 ).

    Aims: To compare the yield of positive computed tomography (CT) brain examinations after the implementation of the National Institute for Clinical Excellence (NICE) or the Scottish Intercollegiate Guidance Network (SIGN) guidelines, in comparable urban populations in two teaching hospitals in England and Scotland. Materials and methods: Four hundred consecutive patients presenting at each location following a head injury who underwent a CT examination of the head according to the locally implemented guidelines were compared. Similar matched populations were compared for indication and yield. Yield was measured according to (1) positive CT findings of the sequelae of trauma and (2) intervention required with anaesthetic or intensive care unit (ICU) support, or neurosurgery. Results: The mean ages of patients at the English and Scottish centres were 49.9 and 49.2 years, respectively. Sex distribution was 64.1% male and 66.4% male respectively. Comparative yield was 23.8 and 26.5% for positive brain scans, 3 and 2.75% for anaesthetic support, and 3.75 and 2.5% for neurosurgical intervention. Glasgow Coma Score (GCS) 10% yield of positive scans. The choice of guideline to follow should be at the discretion of the local institution. The indications GCS <13 and clinical or radiological evidence of a skull fracture are highly predictive of intracranial pathology, and their presence should be an absolute indicator for fast-tracking the management of the patient.

    Full Text Available Diagnosis of hyperthyroidism does not present serious difficulties currently. Distribution of imaging techniques increasing the detection of pituitary adenomas every year. Thyrotropin-producing adenoma is a rare cause of hyperthyroidism. Early detection will alert its errors in treatment strategy, unjustified surgery on the thyroid gland, and will improve the quality of patients life. The article presents two clinical cases of thyroid-stimulating hormone (TSH-secreting pituitary adenomas in patients with different disease duration, and thus the presence of hyperthyroidism complications. Both patients were operated in the Federal Center of Neurosurgery Novosibirsk by transnasal transsphenoidal approach. The resistant euthyroidism was reached postoperatively, but in patients with long-term history of the disease, large size of adenoma in the postoperative period developed secondary adrenal insufficiency and her quality of life is significantly lower, taking into account comorbidities. The period of follow-up consists 3 years and one year respectively.

    Purpose: To present the results of uveal melanomas treated at Nice Teaching Hospital. Methods and Materials: This retrospective study included 886 consecutive patients referred to our clinic for the treatment of uveal melanomas by proton beam radiotherapy from June 1991 to December 2007. Survival rates were determined by using Kaplan-Meier estimates, and prognostic factors were evaluated using the log-rank test or Cox model. Results: The number (percent total) of subjects staged according to the TNM classification system (6th edition) of malignant tumors included 39 stage T1 (4.4%), 420 stage T2 (47.40%), 409 stage T3 (46.16%), and 18 stage T4 (2.03%) patients. The median follow-up was 63.7 months. The Kaplan-Meier overall survival rate at 5 years according to the sixth edition TNM classification was 92% for T1, 89% for T2, 67% for T3, and 62% for T4; and at 10 years, 86% for T1, 78% for T2, 43% for T3, and 41% for T4. Five factors were found to be associated with an increased death rate: advanced age, tumor thickness, largest tumor basal diameter, tumor volume, and tumor volume-to-eyeball volume ratio. The metastasis-free survival rates were 88.3 % at 5 years and 76.4 % at 10 years. The local control rates were 93.9% at 5 years and 92.1% at 10 years. The ocular conservation rates were 91.1% at 5 years and 87.3% at 10 years. Conclusions: We report the results of a large series of patients treated for uveal melanomas with a very long follow-up. Despite the large tumor volume treated, our results were similar to previously published findings relating to proton beam therapy.

OXA-producing A. baumannii strains have been identified in the states of Alagoas, Amazonas, Bahia, Distrito Federal, Espírito Santo, Goiás, Mato Grosso, Mato Grosso do Sul, Minas Gerais, Paraná, Pernambuco, Rio de Janeiro, Rio Grande do Norte, Rio Grande do Sul, Santa Catarina and São Paulo. In some settings, the presence of OXA-23- and/or OXA-143 -producing A. baumannii (so far restricted to Brazil has been endemic and A. baumannii strains carrying blaOXA-23 genes have been detected in hospital wastewater effluents, hence a potential risk to the community and the environment. Although molecular typing by multilocus sequence typing (MLST - Bartual scheme, University of Oxford, http://pubmlst.org/abaumannii/ has revealed the international spread of a clonal complex (CC denominated CC92, in Brazil most OXA-23-producing A. baumannii belong to CC113, CC109 or CC104 clonal complexes. Finally, from a clinical point of view, the main problem of A. baumannii infections is the limited use of antibacterial agents with in vitro activity, often restricted to ampicillin/sulbactam, polymyxin B and/or colistin (polymyxin E.

    The NICE Single Technology Appraisal (STA) process in the UK has been underway for five years. Evidence Review Groups (ERGs) critically appraise submissions from manufacturers on the clinical and cost effectiveness of new technologies. This study analysed the ERGs' assessment of the strengths and weaknesses of 30 manufacturers' submissions to the STA process. Thematic analysis was performed on the textual descriptions of the strengths and weakness of manufacturer submissions, as outlined by the ERGs in their reports. Various themes emerged from the data. These themes related to the processes applied in the submissions; the content of the submission (e.g. the amount and quality of evidence); the reporting of the submissions' review and analysis processes; the reliability and validity of the submissions' findings; and how far the submission had satisfied the STA process objectives. STA submissions could be improved if attention were paid to transparency in the reporting, conduct and justification of review and modelling processes and analyses, as well as greater robustness in the choice of data and closer adherence to the scope or decision problem. Where this adherence is not possible, more detailed justification of the choice of evidence or data is required. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

    Snow is a crucial component of the Arctic sea ice system. Its thickness and thermal properties control heat conduction and radiative fluxes across the ocean, ice, and atmosphere interfaces. Hence, observations of the evolution of snow depth, density, thermal conductivity, and stratigraphy are crucial for the development of detailed snow numerical models predicting energy transfer through the snow pack. Snow depth is also a major uncertainty in predicting ice thickness using remote sensing algorithms. Here we examine the winter spatial and temporal evolution of snow physical properties on first-year (FYI) and second-year ice (SYI) in the Atlantic sector of the Arctic Ocean, during the Norwegian young sea ICE (N-ICE2015) expedition (January to March 2015). During N-ICE2015, the snow pack consisted of faceted grains (47%), depth hoar (28%), and wind slab (13%), indicating very different snow stratigraphy compared to what was observed in the Pacific sector of the Arctic Ocean during the SHEBA campaign (1997-1998). Average snow bulk density was 345 kg m-3 and it varied with ice type. Snow depth was 41 ± 19 cm in January and 56 ± 17 cm in February, which is significantly greater than earlier suggestions for this region. The snow water equivalent was 14.5 ± 5.3 cm over first-year ice and 19 ± 5.4 cm over second-year ice.

    The methodology for the critical assessment of medical interventions is well established. Regulatory agencies and institutions adhere, in principle, to the same standards. This consistency, however, is not always the case in practice. Using the evaluation of the CAPRIE (Clopidogrel versus Aspirin in Patients at risk of Ischemic Events) trial by the British National Institute for Health and Clinical Excellence (NICE) and the German Institute for Quality and Efficiency in Health Care (IQWiG), we illustrate that there was no consensus for the interpretation of possible heterogeneity in treatment comparisons across subgroups. The NICE concluded that CAPRIE demonstrated clinical benefit for the overall intention-to-treat (ITT) population with sufficient robustness to possible sources of heterogeneity. The IQWiG interpreted the alleged heterogeneity as implying that the clinical benefit only applied to the subgroup of patients with a statistically significant result irrespective of the results of the ITT analysis. International standards for the performance and interpretation of subgroup analyses as well as for the assessment of heterogeneity between strata are needed. Copyright © 2010 Elsevier Inc.

ABSTRACT: In this research initiative, the 2013-2014 NASA NICE workshop participants will present best educational practices for incorporating climate change pedagogy. The presentation will identify strategies to enhance instruction of pre-service teachers to aligned with K-12 Science, Technology, Engineering and Mathematics (STEM) standards. The presentation of best practices should serve as a direct indicator to address pedagogical needs to include climate education within a K-12 curriculum Some of the strategies will include inquiry, direct instructions, and cooperative learning . At this particular workshop, we have learned about global climate change in regards to how this is going to impact our life. Participants have been charged to increase the scientific understanding of pre-service teachers education programs nationally to incorporate climate education lessons. These recommended practices will provide feasible instructional strategies that can be easily implemented and used to clarify possible misconceptions and ambiguities in scientific knowledge. Additionally, the presentation will promote an awareness to the many facets in which climate

    This work explores the orbital distribution of minor bodies in the outer Solar System emplaced as a result of a Nice model migration from the simulations of Brasser and Morbidelli. This planetary migration scatters a planetesimal disk from between 29 and 34 au and emplaces a population of objects into the Kuiper Belt region. From the 2:1 Neptune resonance and outward, the test particles analyzed populate the outer resonances with orbital distributions consistent with trans-Neptunian object (TNO) detections in semimajor axis, inclination, and eccentricity, while capture into the closest resonances is too efficient. The relative populations of the simulated scattering objects and resonant objects in the 3:1 and 4:1 resonances are also consistent with observed populations based on debiased TNO surveys, but the 5:1 resonance is severely underpopulated compared to population estimates from survey results. Scattering emplacement results in the expected orbital distribution for the majority of the TNO populations; however, the origin of the large observed population in the 5:1 resonance remains unexplained.

    The impact of clouds on sea ice varies significantly as cloud properties change. Instruments deployed during the Norwegian Young Sea Ice field campaign (N-ICE2015) are used to study how differing cloud properties influence the cloud radiative forcing at the sea ice surface. N-ICE2015 was the first campaign in the Arctic winter since SHEBA (1997/1998) to study the surface energy budget of sea ice and the associated effects of cloud properties. Cloud characteristics, surface radiative and turbulent fluxes, and meteorological properties were measured throughout the field campaign. Here we explore how cloud macrophysical and microphysical properties affect young, thin sea ice during three winter storms from 31 January to 15 February 2015. This time period is of interest due to the varying surface and atmospheric conditions, which showcase the variety of conditions the newly-formed sea ice can experience during the winter. This period was characterized by large variations in the ice surface and near-surface air temperatures, with highs near 0°C when warm, moist air was advected into the area and lows reaching -40°C during clear, calm periods between storms. The advection of warm, moist air into the area influenced the cloud properties and enhanced the downwelling longwave flux. For most of the period, downwelling longwave flux correlates closely with the air temperature. However, at the end of the first storm, a drop in downwelling longwave flux of about 50 Wm-2 was observed, independent of any change in surface or air temperature or cloud fraction, indicating a change in cloud properties. Lidar data show an increase in cloud height during this period and a potential shift in cloud phase from ice to mixed-phase. This study will describe the cloud properties during the three winter storms and discuss their impacts on surface energy budget.

    Introduction: The scope of using no carrier added (NCA) 90 Y [T 1/2 = 64.1 h, E β(max) = 2.28 MeV] obtained from 90 Sr/ 90 Y generator in radiation synovectomy (RSV) is widely accepted. In the present study, the prospect of using 90 Y produced by (n,γ) route in a medium flux research reactor for use in RSV was explored. Methods: Yttrium-90 was produced by thermal neutron irradiation of Y 2 O 3 target at a neutron flux of ~ 1 × 10 14 n/cm 2 .s for 14 d. The influence of various experimental parameters were systematically investigated and optimized to arrive at the most favorable conditions for the formulation of 90 Y labeled hydroxyapatite (HA) using HA particles of 1–10 μm size range. An optimized kit formulation strategy was developed for convenient one-step compounding of 90 Y-HA, which is easily adaptable at hospital radiopharmacy. The pre-clinical biological evaluation of 90 Y-HA particles was studied by carrying out biodistribution and bioluminiscence imaging studies in Wistar rats. The first clinical investigation using the radiolabeled preparation was performed on a patient suffering from chronic arthritis in knee joint by administering 185 MBq 90 Y-HA formulated at the hospital radiopharmacy deploying the proposed strategy. Results: Yttrium-90 was produced with a specific activity of 851 ± 111 MBq/mg and radionuclidic purity of 99.95 ± 0.02%. 90 Y-labeled HA particles (185 ± 10 MBq doses) were formulated in high radiochemical purity (> 99%) and excellent in vitro stability. The preparation showed promising results in pre-clinical studies carried out in Wistar rats. The preliminary results of the first clinical investigation of 90 Y-HA preparation in a patient with rheumatoid arthritis in knee joints demonstrated the effectiveness of the formulation prepared using 90 Y produced via (n,γ) route in the management of the disease. Conclusion: The studies revealed that effective utilization of 90 Y produced via (n,γ) route in a medium flux research

    The care of people with motor neuron disease/amyotrophic lateral sclerosis is often complex and involves a wide multidisciplinary team approach. The National Institute for Health and Care Excellence (NICE) in the UK has produced an evidence based guideline for the management of patients. This has made recommendations, based on clear evidence or consensus discussion. The evidence is often limited and areas for further research are suggested.

    Since the early 1970s therapeutic drug monitoring (TDM) of anti-epilepsy drug (AED) levels has been available to assist in the review process of patients with epilepsy. Routine blood levels were not part of the Quality and Outcomes Framework in the New GP Contract, neither have they been generally recommended in National Guidelines (NICE and SIGN) for the management of patients with epilepsy. To assess the impact of an educational intervention, the New GP Contract and NICE guidelines on the number of requests for TDM. Retrospective study. 39 general practices serving Chester (13), the Rural area surrounding Chester (13) and Ellesmere Port (13). An educational intervention took place in the individual Chester practices between December 2001 and March 2003. For the Rural and Ellesmere Port practices there was one combined event in March 2004 and in March 2007, respectively. Practices were encouraged, not to routinely request TDM, except in certain circumstances. The number of TDM requests for Chester, Rural and Ellesmere Port were obtained from the local laboratory in Chester, plus other nearby hospitals, to provide control groups. The number of TDM requests from primary care for Chester, Rural, Ellesmere Port, Wirral, Crewe, Warrington and Wrexham, April to April, 2002 through to 2008, where available. There has been a fall in the number requests in all districts. The most significant falls were in Chester (47%), Rural (34%) and Ellesmere Port (47%), and corresponded to the time of their educational intervention. The fall has been less marked in Wirral (25%), Crewe (27%), Wrexham (10%) and Warrington (9%). In 2004, the first year after the introduction of the New GP Contract, TDM in Chester and the Rural fell significantly, while those in Ellesmere Port, Wirral, Crewe and Wrexham increased. TDM dropped significantly in Ellesmere Port in the year after their educational intervention. Despite the valproate assay being clinically unhelpful there were still 611 requests

    Describe current dental sedation practice for under 19-year-olds in the UK and compare it with the recommendations of NICE guidance 112. Members of the Society for the Advancement of Anaesthesia in Dentistry and members of the Dental Sedation Teachers Group were invited to participate in an online survey. Two hundred and sixty-six dentists and doctors completed the survey. Eighty-two percent were operator and sedationist (operator-sedationist). Ninety-five percent provided written information and 94% obtained written consent. Eighty-four percent kept a written or electronic sedation record. Eighty-six percent complied with life support training expectations. Eighty-six percent had immediate access to resuscitation equipment. Sixty-seven percent of sedationists reported that treatment could not be completed under sedation for sedation was unsuccessful, 61% said they would schedule general anaesthesia and 54.5% would schedule advanced sedation care. Forty-nine percent believed that a dentist was an appropriate person to provide advanced sedation for 12-18 years. Only 24% thought a dentist should provide advanced sedation for childrensedation was thought to be primary care by 33% and secondary care by 68%. We found good agreement between the current practice of sedation and the recommendations of the NICE guidance 112.

    1997-01-01

    A Centre for Positron Emission Tomography (PET) has been established within the Department of Nuclear Medicine at the Austin and Repatriation Medical Centre in Melbourne. PET is a non-invasive technique based on the use of biologically relevant compounds labelled with short-lived positron-emitting radionuclides such as carbon-11, nitrogen-13, oxygen-15 and fluorine-18. The basic equipment consists of a medical cyclotron (10 MeV proton and 5 MeV deuteron), six lead-shielded hot cells with associated radiochemistry facilities and a whole body PET scanner. During its first five years of operation, the Melbourne PET Centre, has pursued a strong radiolabelling development program, leading to an ambitious clinical program in neurology, oncology and cardiology. This presentation will describe the basic principles of the PET technique and review the cyclotron-produced radioisotopes and radiopharmaceuticals. Radiolabelling development programs and clinical applications are also addressed

    National Institute for Health and Care Excellence (NICE) clinical guidelines (CGs) make recommendations across large, complex care pathways for broad groups of patients. They rely on cost-effectiveness evidence from the literature and from new analyses for selected high-priority topics. An alternative approach would be to build a model of the full care pathway and to use this as a platform to evaluate the cost-effectiveness of multiple topics across the guideline recommendations. In this project we aimed to test the feasibility of building full guideline models for NICE guidelines and to assess if, and how, such models can be used as a basis for cost-effectiveness analysis (CEA). A 'best evidence' approach was used to inform the model parameters. Data were drawn from the guideline documentation, advice from clinical experts and rapid literature reviews on selected topics. Where possible we relied on good-quality, recent UK systematic reviews and meta-analyses. Two published NICE guidelines were used as case studies: prostate cancer and atrial fibrillation (AF). Discrete event simulation (DES) was used to model the recommended care pathways and to estimate consequent costs and outcomes. For each guideline, researchers not involved in model development collated a shortlist of topics suggested for updating. The modelling teams then attempted to evaluate options related to these topics. Cost-effectiveness results were compared with opinions about the importance of the topics elicited in a survey of stakeholders. The modelling teams developed simulations of the guideline pathways and disease processes. Development took longer and required more analytical time than anticipated. Estimates of cost-effectiveness were produced for six of the nine prostate cancer topics considered, and for five of eight AF topics. The other topics were not evaluated owing to lack of data or time constraints. The modelled results suggested 'economic priorities' for an update that differed from

    Evidence Review Groups (ERGs) critically appraise company submissions as part of the National Institute for Health and Care Excellence (NICE) Single Technology Appraisal (STA) process. As part of their critique of the evidence submitted by companies, the ERGs undertake exploratory analyses to explore uncertainties in the company's model. The aim of this study was to explore pre-defined factors that might influence or predict the extent of ERG exploratory analyses. The aim of this study was to explore predefined factors that might influence or predict the extent of ERG exploratory analyses. We undertook content analysis of over 400 documents, including ERG reports and related documentation for the 100 most recent STAs (2009-2014) for which guidance has been published. Relevant data were extracted from the documents and narrative synthesis was used to summarise the extracted data. All data were extracted and checked by two researchers. Forty different companies submitted documents as part of the NICE STA process. The most common disease area covered by the STAs was cancer (44%), and most ERG reports (n = 93) contained at least one exploratory analysis. The incidence and frequency of ERG exploratory analyses does not appear to be related to any developments in the appraisal process, the disease area covered by the STA, or the company's base-case incremental cost-effectiveness ratio (ICER). However, there does appear to be a pattern in the mean number of analyses conducted by particular ERGs, but the reasons for this are unclear and potentially complex. No clear patterns were identified regarding the presence or frequency of exploratory analyses, apart from the mean number conducted by individual ERGs. More research is needed to understand this relationship.

    Full Text Available Klebsiella peumoniae, a capsulated gram negative bacillus is responsible for causing life threatening infections in humans. Carbapenems are the drug of choice for serious infection caused by multidrug resistant Klebsiella pneumoniae. The emergence of carbapenem resistance has made it extremely difficult to treat such infections resulting in significant morbidity and mortality. Aims: To study the prevalence of carbapenem resistance using ertapenem as a marker and to detect Klebsiella pneumoniae Carbapenemase (KPC producing Klebsiella pneumoniae as a mechanism of resistance. Material and Methods: The study included 102 patients from which Klebsiella pneumoniae isolated. Identification and antibiotic susceptibility testing of Klebsiella pneumoniae was performed on miniAPI (Analytical Profile Index, Semiautomated bacterial identification system according to Clinical and Laboratory Standards Institute (CLSI guidelines of 2011. The modified Hodge test was performed for detection of Carbapenemase production. Patient’s clinical and demographic details along with risk factors and co-morbid conditions, type of response to antimicrobial therapy and mortality were collected. Results: The prevalence of carbapenem resistance was found to be 30.41% with 16.6% KPC producing Klebsiella pneumoniae. The co-morbid conditions like immunocompromised state (p =0.042, prior antibiotics therapy (p=0.047, previous hospitalization (p =0.021, intensive care unit stay (p=0.047 and use of indwelling devices (p =0.013 were found to be significantly associated with carbapenem resistance. Adverse clinical outcomes (death or worsening among patients infected with ertapenem resistant patients was found to be statistically significant than ertapenem sensitive strains (p =0.008.

    Most available information on carbapenemase-producing Enterobacteriaceae (CPE) is usually associated with specific types of infection or patient or with descriptions of outbreaks. The aim of this study was to comprehensively analyse the clinical epidemiology, clinical features and outcomes of colonisation and infections due to CPE in Spain. A multicentre prospective cohort study was carried out in 34 Spanish hospitals from February to May 2013. All new patients testing positive for CPE in clinical samples were included. Logistic regression was used to identify predictors of mortality. Overall, 245 cases were included. The most frequent organism was Klebsiella pneumoniae (74%) and the carbapenemases belonged to the OXA-48 (74%), metallo-β-lactamase (MBL) (24%) and KPC (2%) groups. Acquisition was nosocomial in 145 cases (60%) and healthcare-associated (HCA) in 91 (37%); 42% of the latter were nursing home residents, in whom OXA-48-producing K. pneumoniae ST405 predominated. MBLs and OXA-48 predominated in ICU and medical patients, respectively. Overall, 67% of patients had infections. The most frequent infections identified in this study were urinary tract (43%) and skin structure (21%) infections, and 10% of infections were bacteraemic. Crude mortality was 20%. Inappropriate antibiotic therapy was independently associated with an increased risk of death (OR = 3.30; 95% CI: 1.34-8.11). We found some differences in the epidemiology of CPE depending on the type of carbapenemase produced. Although a low proportion of CPE infections were bacteraemic, active antibiotic therapy was a protective factor for reducing mortality. Copyright © 2015 The British Infection Association.

    Acinetobacter spp. are important causes of nosocomial infections. They possess various antibiotic resistance mechanisms including extended spectrum beta lactamases (ESBLs). The aim of this study was to determine antibiotic resistance profile of Acinetobacter clinical isolates especially among ESBL-producing strains and to investigate the antimicrobial effects of oleo-gum-resin extract and essential oil of Ferula gummosa Boiss. 120 Acinetobacter strains were isolated from various clinical samples of hospitalized patients in Baqiyatallah hospital, Tehran during 2011-2012. Antibiotic susceptibility test was performed on the isolates using disk diffusion method. To detect and confirm the ESBL-positive isolates, phenotypic and genotypic tests were performed. Three types of F. gummosa oleo-gum-resin extracts and essential oils were prepared and the bioactive components of F. gummosa Boiss extracts were determined by GC-Mass chromatography. F. gummosa antimicrobial activity was evaluated against standard strain of Acinetobacter baumannii (ATCC19606) as well as Acinetobacter clinical isolates using well and disk diffusion methods. Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were determined by broth microdilution method. 46 isolates were resistant to all tested antibiotics. All clinical isolates were resistant to cefotaxime. 12.94% of the isolates were phenotypically ESBL-producing among which 94.2% carried ESBL genes ( bla PER-1 , bla OXA-4 and bla CTX-M ) detected by PCR. Oleo-gum-resin of F. gummosa had significant antibacterial activity and alcoholic essential oil had higher inhibitory effect on Acinetobacter strains (MIC of 18.75 mg/ml). Ferula gummosa extract contained components with well-known antimicrobial effects.

    2016-09-01

    The treatment of severe full-thickness skin defects represents a significant and common clinical problem worldwide. A bio-engineered autologous skin substitute would significantly reduce the problems observed with today's gold standard. Within 15 years of research, the Tissue Biology Research Unit of the University Children's Hospital Zurich has developed autologous tissue-engineered skin grafts based on collagen type I hydrogels. Those products are considered as advanced therapy medicinal products (ATMPs) and are routinely produced for clinical trials in a clean room facility following the guidelines for good manufacturing practice (GMP). This article focuses on hurdles observed for the translation of ATMPs from research into the GMP environment and clinical application. Personalized medicine in the field of rare diseases has great potential. However, ATMPs are mainly developed and promoted by academia, hospitals, and small companies, which face many obstacles such as high financial burdens.

  12. Temporal changes of radioactive contamination of Ploučnice river Inundation area, Czech Republic

    2010-01-01

    The inundation area of Ploučnice river has been contaminated by natural radionuclides during the early mining of the uranium ore deposit in the region of Stráž pod Ralskem, Northern Bohemia, i.e. in the seventies and in the eighties of the last century. The evaluation of the level of contamination has faced many problems. During several floods that occurred after the primary contamination, the contaminants were spread to a relatively large territory, but the level of contamination became fairly variable. Large regions have not been affected at all, and measured values of gamma dose rate are comparable with the values of natural background. On the other hand, a higher contamination can be found at small areas, often situated far from the river - for example in catchwater drains. Moreover, many contaminated areas are located in places that are difficult to reach. The topographical orientation is also intricate in such places. A study of temporal changes of contamination was based on a comparison of data obtained using two different methods: airborne gamma-ray spectrometry and detailed ground gamma dose rate and in situ gamma spectrometry measurements

    Full Text Available Objective: To evaluate the prevalence of extended spectrum beta-lactamases (ESBL in clinical isolates from burn patients using phenotypic and genotypic analyses. Methods: During 2015–2016, a total of 126 samples were collected at a tertiary care hospital, Islamabad. Antibiotic sensitivity and ESBL prevalence were evaluated according to the Clinical Laboratory and Standards Institute, and molecular analysis of the CTX-M type ESBL gene was performed in 225 bacterial isolates from these samples. Results: The most prevalent bacterial species were Escherichia coli (28.4%, Pseudomonas aeruginosa (22.2%, Staphylococcus aureus (19.6%, Klebsiella pneumoniae (16.4%, and coagulase-negative staphylococci (13.3%. Of the 225 bacterial isolates, 89 (39.5% were found to be ESBL producers. The isolates were highly susceptible to meropenem (88% and imipenem (84%, followed by the aminoglycoside amikacin (81%. Molecular epidemiology of the ESBL isolates indicated 19% prevalence of CTX-M. Resistance to antibiotics was exhibited by 28% isolates. Conclusions: In the present study, bacteria such as P. aeruginosa, K. pneumoniae, S. aureus, and E. coli isolated from burn patients exhibited resistance to one or more antibiotics and produced large amounts of ESBL. Further studies are needed to investigate the virulence and epidemiology of CTX-M type ESBL in clinical isolates from burn patients.

    Recently discovered broadly neutralizing antibodies (bNAbs) against HIV-1 demonstrate extensive breadth and potency against diverse HIV-1 strains and represent a promising approach for the treatment and prevention of HIV-1 infection. The breadth and potency of these antibodies have primarily been evaluated by using panels of HIV-1 Env-pseudotyped viruses produced in 293T cells expressing molecularly cloned Env proteins. Here we report on the ability of five bNAbs currently in clinical development to neutralize circulating primary HIV-1 isolates derived from peripheral blood mononuclear cells (PBMCs) and compare the results to those obtained with the pseudovirus panels used to characterize the bNAbs. The five bNAbs demonstrated significantly less breadth and potency against clinical isolates produced in PBMCs than against Env-pseudotyped viruses. The magnitude of this difference in neutralizing activity varied, depending on the antibody epitope. Glycan-targeting antibodies showed differences of only 3- to 4-fold, while antibody 10E8, which targets the membrane-proximal external region, showed a nearly 100-fold decrease in activity between published Env-pseudotyped virus panels and PBMC-derived primary isolates. Utilizing clonal PBMC-derived primary isolates and molecular clones, we determined that the observed discrepancy in bNAb performance is due to the increased sensitivity to neutralization exhibited by 293T-produced Env-pseudotyped viruses. We also found that while full-length molecularly cloned viruses produced in 293T cells exhibit greater sensitivity to neutralization than PBMC-derived viruses do, Env-pseudotyped viruses produced in 293T cells generally exhibit even greater sensitivity to neutralization. As the clinical development of bNAbs progresses, it will be critical to determine the relevance of each of these in vitro neutralization assays to in vivo antibody performance.

    Clinical Audit plays an important role in the evaluation of care and clinical outcomes for all patients. In conjunction with the respiratory nurse specialist a retrospective chart audit of the regional lung cancer service was undertaken at the Midlands Regional Hospital Mullingar (MRHM). The lung cancer service has been established for four years and has set its standards in line with NICE guidelines and Irish guidelines for the clinical management of lung cancer. An audit tool was developed by the audit facilitator in conjunction with the respiratory nurse specialist and key department personnel. The tool aimed to measure length of time taken for key steps in the patients care pathway. A pilot audit was carried out and the tool was evaluated. The audit tool provided accurate recording of information at key points in the patient’s care which allows for a thorough service evaluation. The data collected and analysed gives vital information on the quality of service, and showed where there are deficits in service provision that need to be addressed.

    Use of antibiotics in food animals may contribute to development and spread of resistant organisms, particularly so in some countries. The aim of this study was two-fold; first, to establish the prevalence of extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli in chicken production in a region within Romania. Second, to study the relatedness of ESBL-producing E. coli isolates recovered from broilers, abattoir workers where the chickens were slaughtered and from the human clinical specimens from two regional hospitals. The results indicated a very high (69%) rate of carriage of ESBL and AmpC-producing E. coli in chickens with 36% CTX-M producers. Sequencing showed that chickens in Romania have the highest worldwide prevalence (53%) of blaCTX-M-15 reported in poultry E. coli isolates. The majority (53%) of the extended-spectrum cephalosporin-resistant E. coli carried plasmid-mediated blaampC genes, mostly blaCMY-2 type, one of the highest prevalences reported in Europe. The predominant CTX-M type found in the human clinical E. coli isolates was blaCTX-M-15 and most isolates coharbored blaOXA-1, blaTEM, and aac(6')-ib-cr. The majority (60%) of the human clinical isolates belonged to the pandemic virulent clone B2-ST131. The clonal relationship between broiler and the human CTX-M-producing E. coli isolates was assessed by macrorestriction pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST), which indicated strain diversity with no common STs found between human and poultry isolates. Moreover, IncI1 was the most prevalent replicon found in broiler ESBL-producing E. coli isolates and also in transconjugants, indicating that plasmids and not clonal spread may play a role in the transfer of blaCTX-M genes. This study identifies a high prevalence of ESBL-producing E. coli from broiler chickens in Romania with a high occurrence incidence of blaCTX-M-15, which reflects the main ESBL type found in human E. coli infections in this

    Objectives To compare how patients with chest pain would be investigated, based on the two guidelines available for UK cardiologists, on the management of patients with stable chest pain. The UK National Institute of Clinical Excellence (NICE) guideline which was published in 2010 and the European society of cardiology (ESC) guideline published in 2013. Both guidelines utilise pre-test probability risk scores, to guide the choice of investigation. Design We undertook a large retrospective study to investigate the outcomes of stress echocardiography. Setting A large tertiary centre in the UK in a contemporary clinical practice. Participants Two thirds of the patients in the cohort were referred from our rapid access chest pain clinics. Results We found that the NICE risk score overestimates risk by 20% compared to the ESC Risk score. We also found that based on the NICE guidelines, 44% of the patients presenting with chest pain, in this cohort, would have been investigated invasively, with diagnostic coronary angiography. Using the ESC guidelines, only 0.3% of the patients would be investigated invasively. Conclusion The large discrepancy between the two guidelines can be easily reduced if NICE adopted the ESC risk score. PMID:26673458

    Acinetobacter species particularly Acinetobacter baumannii (A. baumannii) have been widely reported as broad-spectrum antibiotic resistant pathogens. Expression of various types of metallo beta-lactamases (MBL), classified as Ambler class B, has been associated with carbapenem resistance. Here, we attempted to assess the frequency of extensively drug-resistant (XDR) and MBL-producing A. baumannii among clinical isolates. 86 clinical A. baumannii strains were collected from 2014 to 2015 and their susceptibility to meropenem (10 μg), imipenem (10 μg), azteronem (30 μg), pipracillin (100 μg) tazobactam (110 μg), tobramycin (10 μg), fosfomycin (200 μg), rifampicin (5 μg), colistin (10 μg), tigecycline (15 μg), sulbactam/ampicillin (10 μg + 10 μg) and polymixin B (300 U) was evaluated using disk diffusion method. The MBL-producing isolates were screened using combined disc diffusion method. Furthermore, the presence of blaVIM, blaIMP, blaSPM, blaGIM, blaSIM and blaNDM was detected by PCR. 34.9% of isolates were recovered from bronchoalveolar lavage (BAL). 81 (94.2%) and 62 (71.2%) isolates were multidrug resistance (MDR) and XDR, respectively. 44 (51.2%) and 65 (75.6%) isolates were MBL-producing strains with resistance to imipenem and meropenem, respectively. 2 (2.3%), 13 (15.1%), 2 (2.3%), 4 (4.7%) and 2 (2.3%) isolates carried blaVIM, blaIMP, blaSPM, blaGIM and blaSIM genes, respectively. Our data showed that the rate of XDR and MBL A. baumannii is on the rise. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The traditional needs assessment used in developing continuing medical education programs typically relies on surveying physicians and tends to only capture perceived learning needs. Instead, using tools available in electronic medical record systems to perform a clinical audit on a physician's practice highlights physician-specific practice patterns. The purpose of this study was to test the feasibility of implementing an electronic clinical audit needs assessment process for family physicians in Canada. A clinical audit of 10 preventative care interventions and 10 chronic disease interventions was performed on family physician practices in Alberta, Canada. The physicians used the results from the audit to produce personalized learning needs, which were then translated into educational programming. A total of 26 family practices and 4489 patient records were audited. Documented completion rates for interventions ranged from 13% for ensuring a patient's tetanus vaccine is current to 97% of pregnant patients receiving the recommended prenatal vitamins. Electronic medical record-based needs assessments may provide a better basis for developing continuing medical education than a more traditional survey-based needs assessment. This electronic needs assessment uses the physician's own patient outcome information to assist in determining learning objectives that reflect both perceived and unperceived needs.

    Full Text Available Shiga toxin-producing Escherichia coli (STEC are significant public health threats. Although STEC O157 are recognized foodborne pathogens, non-O157 STEC are also important causes of human disease. We characterized 10 O157:H7 and 15 non-O157 clinical STEC derived from British Columbia (BC. Eae, hlyA, and stx were more frequently observed in STEC O157, and 80 and 100% of isolates possessed stx1 and stx2, respectively. In contrast, stx1 and stx2 occurred in 80 and 40% of non-O157 STEC, respectively. Comparative genomic fingerprinting (CGF revealed three distinct clusters (C. STEC O157 was identified as lineage I (LI; LSPA-6 111111 and clustered as a single group (C1. The cdi gene previously observed only in LII was seen in two LI O157 isolates. CGF C2 strains consisted of diverse non-O157 STEC while C3 included only O103:H25, O118, and O165 serogroup isolates. With the exception of O121 and O165 isolates which were similar in virulence gene complement to STEC O157, C1 O157 STEC produced more Stx2 than non-O157 STEC. Antimicrobial resistance (AMR screening revealed resistance or reduced sensitivity in all strains, with higher levels occurring in non-O157 STEC. One STEC O157 isolate possessed a mobile blaCMY-2 gene transferrable across genre via conjugation.

    Background: the occurrence of the different types of Extended spectrum beta Lactamase producing Escherichia coli with the, Sulphurhydryl variable, Temonera and the Cefotaximase have been on the rise Aim: The study was to determine the prevalence of extended spectrum beta lactamase gene resistance across the clinical isolates of hospitalized patients. Materials and Method: Three hundred and fifty isolates of Escherichia coli were received from different clinical specimens. The susceptibility profile of the isolates against 10 different antibiotics was examined, the MICs (Minimum Inhibitory Concentration) for ceftazidime were also determined using micro-broth dilution assay. Isolates showing MIC ≥ 6 μg/ml for ceftazidime were screened for ESBL (PCT)phenotypic confirmatory test and subjected to PCR (polymerase chain reaction) to further. Results: By disk diffusion test, there was resistance to ceftazidime and cefotaxime were 180(51.4%) and 120 (34.2%) respectively. However, all strains were susceptible to imipenem. 250 isolates showed MICs≥ 6 μg/ml for ceftazidime of which 180 (72%) were positive for extended spectrum beta lactamase. The prevalence of Sulphurhydryl variable, Temonera and the Cefotaximase among these isolates were 17.1%, 6.6% and 17%, respectively. Conclusion: For the identification of extended spectrum beta lactamase producing isolates it is recommended that clinical laboratories adopt simple test based on Cinical laboratory standard institute recommendation for confirming extended spectrum beta lactamase production in enterobacteriacea species.

    Little is known about attributes that elicit romantic desirability in early adolescence. The current study, with a sample of 531 sixth-grade students (45% boys) attending ethnically diverse middle schools, used a resource control framework to explore which self-reported behaviors (e.g., empathy and aggression) and peer-reported status (e.g., acceptance and perceived popularity) predict the likelihood of being considered romantically desirable (i.e., receiving at least one "crush" nomination from an opposite sex grademate). Self-reported empathy was positively associated with students' romantic desirability (primarily for those with high peer acceptance), whereas self-reported aggression on its own did not. Both peer-acceptance and popularity also were positively associated with students' romantic desirability, and aggressive behavior reduced popularity's effect. Although aggression may be integral for obtaining high peer status across cultures, prosocial behaviors were romantically valued. Our findings suggest that peer-vetted social status elicits romantic interest and during early adolescence, nice guys and gals really do not finish last.

    Timely identification of extended-spectrum β-lactamase (ESBL) bacteremia can improve clinical outcomes while minimizing unnecessary use of broad-spectrum antibiotics, including carbapenems. However, most clinical microbiology laboratories currently require at least 24 additional hours from the time of microbial genus and species identification to confirm ESBL production. Our objective was to develop a user-friendly decision tree to predict which organisms are ESBL producing, to guide appropriate antibiotic therapy. We included patients ≥18 years of age with bacteremia due to Escherichia coli or Klebsiella species from October 2008 to March 2015 at Johns Hopkins Hospital. Isolates with ceftriaxone minimum inhibitory concentrations ≥2 µg/mL underwent ESBL confirmatory testing. Recursive partitioning was used to generate a decision tree to determine the likelihood that a bacteremic patient was infected with an ESBL producer. Discrimination of the original and cross-validated models was evaluated using receiver operating characteristic curves and by calculation of C-statistics. A total of 1288 patients with bacteremia met eligibility criteria. For 194 patients (15%), bacteremia was due to a confirmed ESBL producer. The final classification tree for predicting ESBL-positive bacteremia included 5 predictors: history of ESBL colonization/infection, chronic indwelling vascular hardware, age ≥43 years, recent hospitalization in an ESBL high-burden region, and ≥6 days of antibiotic exposure in the prior 6 months. The decision tree's positive and negative predictive values were 90.8% and 91.9%, respectively. Our findings suggest that a clinical decision tree can be used to estimate a bacteremic patient's likelihood of infection with ESBL-producing bacteria. Recursive partitioning offers a practical, user-friendly approach for addressing important diagnostic questions. © The Author 2016.

    123 I capsules produced by NIRS which are believed to be uncontaminated by radioactive impurities other than 125 I were compared with commercial 123 I capsules regarding gamma-ray spectra, thyroid phantoms and clinical scintigrams. Absorbed radiation doses of 123 I contaminated with nuclides other than 123 I to thyroid and whole body were also estimated. Regarding gamma-ray spectra, any nuclides other than 125 I(0.53%) did not contaminate in 123 I produced by NIRS, and it was superior to commercial capsules. Regarding phantoms and clinical scintigrams, background counts around the thyroid gland seemed to be slightly higher in commercial capsules than that produced by NIRS because of contamination with other nuclides. Exposed doses in thyroid and whole body were counted. Ratios in thyroid and whole body were increased by 30% and 9%, respectively in 123 I produced by NIRS because of contamination with 0.53% of 125 I in the event that the intake ratio of thyroid was determined as 25%. In commercial capsules the doses in thyroid and whole body were increased by 500% and 150%, respectively. Doses of commercial capsules and NIRS capsules were 7.87 rad and 1.72 rad, respectively per 100 μCi in thyroid. The ratio of NIRS capsules to commercial capsules in thyroid was 1/4.6, and that in the whole body was less than 1/2. (Ichikawa, K.)

    Full Text Available Abstract Background Description of the clinical pictures of patients colonized or infected by ESBL-producing Enterobacteriaceae isolates and admitted to hospital are rather scarce in Europe. However, a better delineation of the clinical patterns associated with the carriage of ESBL-producing isolates may allow healthcare providers to identify more rapidly at risk patients. This matter is of particular concern because of the growing proportion of ESBL-producing Enterobacteriaceae species isolates worldwide. Methods We undertook a descriptive analysis of 114 consecutive patients in whom ESBL-producing Enterobacteriaceae isolates were collected from clinical specimens over a 20-month period. Clinical data were obtained through retrospective analysis of medical record charts. Microbiological cultures were carried out by standard laboratory methods. Results The proportion of ESBL-producing Enterobacteriaceae strains after exclusion of duplicate isolates was 4.5% and the incidence rate was 4.3 cases/1000 patients admitted. Healthcare-associated acquisition was important (n = 104 while community-acquisition was less frequently found (n = 10. Among the former group, two-thirds of the patients were aged over 65 years and 24% of these were living in nursing homes. Sixty-eight (65% of the patients with healthcare-associated ESBL, were considered clinically infected. In this group, the number and severity of co-morbidities was high, particularly including diabetes mellitus and chronic renal insufficiency. Other known risk factors for ESBL colonization or infection such as prior antibiotic exposure, urinary catheter or previous hospitalisation were also often found. The four main diagnostic categories were: urinary tract infections, lower respiratory tract infections, septicaemia and intra-abdominal infections. For hospitalized patients, the median hospital length of stay was 23 days and the average mortality rate during hospitalization was 13% (Confidence

    To compare the sensitivity and specificity of different phenotypic methods for detection of Amp C betalactamase producing bacteria. Study Design: Analytical study. Place and Duration of Study: Department of Microbiology, Army Medical College / National University of Sciences and Technology (NUST), Islamabad, Pakistan, from June 2010 to December 2010. Methodology: A total of 150 clinical isolates were screened for presence of Amp C beta-lactamase by using the cefoxitin disc. The confirmatory methods evaluated were inhibitor based assay (boronic acid), Amp C disc test and Amp C Etest. Three dimensional enzyme extract assay was used as the reference method for determining the sensitivity and specificity. Results: Among the total isolates tested, 62.8% bacteria showed the presence of Amp C beta-lactamase by standard three dimensional enzyme extract assay. Among the three methods compared, boronic acid disk test found out to be highly sensitive (88%) and specific (92%) for the detection of Amp C beta-lactamase producing bacteria. Conclusion: Detection of Amp C production is crucial in order to establish the antibiotic therapy and to attain the favourable clinical outcomes. Implementation of simple tests like boronic acid disk tests in the laboratories will help to alleviate the spread of Amp C beta-lactamase harboring organisms. (author)

A cross-sectional survey was conducted in Texas in 2008 and 2009 to determine beliefs about reporting cattle with clinical signs consistent with foot-and-mouth disease (FMD) either prior to (scenario 1) or during an on-going outbreak of FMD (scenario 2). Two questionnaires were developed and distributed to Texas cow-calf producers in order to evaluate their behavioral, control, and normative beliefs related to disease reporting. The context for each behavior was provided through the use of scenarios, and belief strength was measured using a 7-point Likert-like scale. Beliefs were compared across scenarios and demographic categories, and the effect of scenario on belief examined using ordinal logistic regression. Respondents agreed that reporting clinically suspect cases would have positive economic and emotional consequences; however, when an outbreak was known to be present, producers were less likely to agree with many of the positive outcomes of reporting. Important barriers to disease reporting indicated by producers included a lack of knowledge related to clinical signs of highly contagious cattle diseases and which cattle are at risk of contracting FMD. In general, beliefs about barriers to reporting did not differ based on scenario. Veterinarians and regulatory authorities were the groups perceived to most strongly expect disease reporting, regardless of the scenario. Risk education for producers related to clinical signs of reportable livestock diseases, post-reporting procedures, and an understanding of FMD introduction and spread may improve the reporting of cattle with clinical signs consistent with FMD.

    Carbapenemase-producing Enterobacteriaceae (CPE) are becoming of immediate concern for infection control policies. Prompt detection of CPE on health care setting admission is crucial to halt the spread of an outbreak. We report a cluster of 13 Klebsiella pneumoniae carbapenemase (KPC)-2-producing K pneumoniae cases in a tertiary care hospital.The objective of this study was to identify contributing factors originating the outbreak. An outbreak investigation was conducted using descriptive epidemiology, observation of health care practices, and interviews of management staff. A root cause analysis was performed to identify patent and latent failures of infection control measures using the association of litigation and risk management method. The main patent failure was the delay in identifying KPC-2-producing K pneumoniae carriers. Contributing factors were work and environmental factors: understaffing, lack of predefined protocols, staff members' characteristics, and underlying patients' characteristics. Latent failures were as follows: no promotion of the national guidelines for prevention of CPE transmission, no clear procedure for the management of patients hospitalized abroad, no clear initiative for promoting a culture of quality in the hospital, biologic activity recently outsourced to a private laboratory, and poor communication among hospital members. Clinical management should be better promoted to control hospital outbreaks and should include team work and safety culture.

    Cardiovascular disease is the leading cause of death in modern industrialized countries with an aging population. This fact has fueled the need for innovative diagnostic testing intended to improve coronary artery disease (CAD) patient care. Detection of myocardial ischemia using myocardial perfusion imaging (MPI) plays an important role for CAD diagnosis and the prediction of future risk of cardiovascular events. Positron emission tomography (PET) MPI has high diagnostic accuracy and can estimate regional myocardial blood flow (MBF) in patients with CAD. Rubidium-82 ( 82 Rb) is a generator-produced PET myocardial perfusion tracer and has been widely used in North America in clinical practice. 82 Rb PET has recently become available in some cardiovascular centers in Europe and Japan. Clinical trials are expected in both regions. 82 Rb PET has high diagnostic accuracy and recent data have shown its prognostic value. Thus, 82 Rb PET would greatly contribute to CAD patients' care. 82 Rb PET can also be used to quantify MBF. This review describes the current status of 82 Rb MPI from basic principles to clinical implications. This paper also highlights the recent development of MBF quantification using 82 Rb PET.

    The purpose of this study is to describe our initial experience of imaging adults with localisation-related epilepsy using MR imaging at 3.0T. We discuss the findings in the context of the recently released NICE guidelines that provide detailed advice on imaging people with epilepsy in the UK. 120 consecutive people over the age of 16 years with localisation-related epilepsy were referred for clinical MR examinations from a regional neuroscience centre in England. None of the people had had MR examinations prior to the present study. High resolution MR imaging was performed taking advantage of the high field strength and high performance gradients of the system. Two experienced neuroradiologists reported on the examinations independently and the presence and type of pathology was recorded. There was complete agreement between the two reporters in all 120 cases. The overall frequency of abnormalities shown by MR was 31/120 (26%) and the commonest abnormality shown was mesial temporal sclerosis found in 10/120 (8%). Tumours were shown in 4/120, all of which appeared low grade as judged by imaging criteria. Epilepsy is the commonest neurological condition and demands a significant resource in order to provide good care for sufferers. Recent guidelines published in the UK have suggested that the majority of people with epilepsy should receive brain MR as part of their routine assessment. Our work shows that using the most sophisticated MR imaging in a highly selected population there is a modest pick-up rate of brain abnormalities. If a widespread epilepsy-imaging programme is started the detection rate is likely to be much lower. Although MR is acknowledged to be a reliable way of detecting pathology in people with epilepsy there is a dearth of information studying the health economics of imaging epilepsy in relation to patient management and outcomes

    Full Text Available The sequence-independent single primer amplification (SISPA method was performed to identify a virus in 17 clinical respiratory samples producing uncharacterized cytopathic effects in LLC-MK2 cells. Sequence analysis of 600-1600 bp amplicons allowed the identification of six viruses (one influenza C, two parechovirus-3 and three cardioviruses. Genomic sequences of the cardioviruses showed similarities with those of the recently-described Saffold virus strain although significant variation was present in the viral surface EF and CD loops. These results demonstrate the usefulness of SISPA for identifying emerging viruses and also known viruses not easily identified by standard virological methods.

    Aspergillus fumigatus, a well-known human and animal pathogen causing aspergillosis, has been historically identified by morphological and microscopic features. However, recent studies have shown that species identification on the basis of morphology alone is problematic. The aim of this work was to confirm the taxonomic state at specie level of a set of clinical (human and animal) and animal environment A. fumigatus strains identified by morphological criteria applying a PCR-RFLP assay by an in silico and in situ analysis with three restriction enzymes. The A. fumigatus gliotoxin-producing ability was also determined. Previous to the in situ PCR-RFLP analysis, an in silico assay with BccI, MspI and Sau3AI restriction enzymes was carried out. After that, these enzymes were used for in situ assay. All A. fumigatus strains isolated from corn silage, human aspergillosis and bovine mastitis and high per cent of the strains isolated from cereals, animal feedstuff and sorghum silage were able to produce high gliotoxin levels. Also, all these strains identified by morphological criteria as A. fumigatus, regardless of its isolation source, had band patterns according to A. fumigatus sensu stricto by PCR-RFLP markers. Aspergillus fumigatus is a well-known human and animal pathogen causing aspergillosis. In this study, clinical (human and animal) and animal environment strains were able to produce high gliotoxin levels and had band profiles according to A. fumigatus sensu stricto by PCR-RFLP markers. The results obtained here suggest that strains involved in human and animal aspergillosis could come from the animal environment in which A. fumigatus is frequently found. Its presence in animal environments could affect animal health and productivity; in addition, there are risks of contamination for rural workers during handling and storage of animal feedstuffs. © 2013 The Society for Applied Microbiology.

  18. Generation of a Vero-Based Packaging Cell Line to Produce SV40 Gene Delivery Vectors for Use in Clinical Gene Therapy Studies

    Full Text Available Replication-defective (RD recombinant simian virus 40 (SV40-based gene delivery vectors hold a great potential for clinical applications because of their presumed non-immunogenicity and capacity to induce immune tolerance to the transgene products in humans. However, the clinical use of SV40 vectors has been hampered by the lack of a packaging cell line that produces replication-competent (RC free SV40 particles in the vector production process. To solve this problem, we have adapted the current SV40 vector genome used for the production of vector particles and generated a novel Vero-based packaging cell line named SuperVero that exclusively expresses the SV40 large T antigen. SuperVero cells produce similar numbers of SV40 vector particles compared to the currently used packaging cell lines, albeit in the absence of contaminating RC SV40 particles. Our unique SV40 vector platform named SVac paves the way to clinically test a whole new generation of SV40-based therapeutics for a broad range of important diseases.

    We conducted a prospective observational study on clinical and subclinical mastitis in 30 commercial meat-producing sheep flocks from 2 regions of the province of Quebec, Canada. A total of 2,792 ewes selected in late gestation were followed from lambing to weaning of lambs. The incidence of clinical mastitis for the total lactation period (average of 58 days) ranged among flocks from 0 to 6.6%, with a median of 1.2%. The most frequently isolated bacteria from the cases of clinical mastitis, in pure or mixed culture, were Mannheimia haemolytica (26%), Staphylococcus aureus (23%), and coagulase-negative staphylococci (17%). Incidence of clinical mastitis was higher in ewes that gave birth to 3 or more lambs and from the Estrie region, and was associated with an increase in ewe mortality, an increase in lamb mortality at the litter level, and a decrease in lamb's weaning weight for lambs born in multiple litter size or from ewes >or=4 years old. Among 354 selected ewes with clinically normal udder at the end of lactation, 28.8% had potentially pathogenic bacteria isolated from milk. The most prevalent bacteria were S. aureus (9.3%) and coagulase-negative staphylococci (9.3%). The risk of having a positive culture in at least one half was different between the two regions. Prevalence of ewes (n=261) with California Mastitis Test (CMT) positive result in at least one half was 24.1 and 14.9% using a cut-off of >or=1+ and >or=2+, respectively. Prevalence of culture-positive udder halves was 11.7% for CMT-negative compared with 53.6% for CMT 3+ halves. CMT status was positively associated with the isolation of coagulase-negative staphylococci, M. haemolytica, S. aureus, and various Streptococcus species, but not with other isolated bacteria. Additionally, prevalence of CMT-positive halves was higher in ewes from the Estrie region, aged of >or=4 years versus 1 year, having clinical mastitis previously detected in the lactation and/or with low body condition score.

  20. Pain, physical dependence and pseudoaddiction: redefining addiction for 'nice' people?

    2009-03-01

    The undertreatment of pain has increasingly been framed as both a public health problem and a human rights issue. The application of rights-based discourses to the field of pain management has provided an important means of critiquing "opiophobia" amongst healthcare professionals and challenging current criminal-legal and regulatory sanctions on the distribution of opiate medications. This movement would therefore appear to align with harm reduction advocacy and longstanding criticisms of international drug policies. However, discourses on pain management rest on moral as well as medical assumptions about who has pain and who needs drugs. In this paper, we critically examine discourses on pain management and addiction exemplified in academic and clinical literature produced by and for physicians providing guidance on the provision of opiates for the relief of chronic pain. Our analysis reveals that discourses on pain management and the right to pain relief reify distinctions between the 'deserving pain patient' and the 'undeserving addict', serving both to further stigmatise people labelled as 'addicts' and delegitimise claims to pain they might voice. Present efforts to secure access to pain relief as a human right are likely to undermine, rather than advance, the rights of so-called 'drug addicts'.

  1. Clinically Relevant ESBL-Producing K. pneumoniae ST307 and E. coli ST38 in an Urban West African Rat Population

    Full Text Available High-risk ESBL-producing Enterobacteriaceae (ESBL-E have been described in wild birds and rodents worldwide. Rats are of special interest not only due to their indicator role for environmental pollution with multi-resistant bacteria but also as possible infection source. Data on the presence of high-risk ESBL-E in urban wildlife from Africa remain scarce, however. Twenty-nine animals from three different rat (Rattus species were captured in the city of Conakry (Guinea, West Africa in 2015. Rectal swabs were analyzed for ESBL-E using selective media. Species typing and phenotypic antimicrobial resistance analysis to broad-spectrum beta-lactams and other classes of antimicrobials was performed for Enterobacteriaceae-like isolates using the VITEK®2 system (BioMérieux, Germany. Confirmed ESBL-producing E. coli and K. pneumoniae were whole-genome sequenced and resistance genes, phylogenetic background and genes related to bacterial fitness and virulence were analyzed. In total, six of twenty-nine rats (20% carried ESBL-E (K. pneumoniae and E. coli. All ESBL-producers were multi-drug resistant with blaCTX−M−15 as the dominating ESBL-type. Interestingly, ESBL-associated clonal lineages E. coli ST38 and K. pneumoniae ST307 were found. The ESBL-plasmid in K. pneumoniae ST307 revealed high sequence similarities to pKPN3-307_TypeC, a >200 kbp IncFII plasmid originating from a human clinical ST307 isolate. This was in contrast to the core genome: the rat isolate was distantly related to the human clinical ST307 isolate (27 SNPs/Mbp. In addition, we identified π-fimbrial, capsule 2, and glycogen synthesis clusters in the rodent ST307 isolate, whose involvement in the adaptation to survival outside the host and in human urinary tracts has been suggested. Our results demonstrate the presence of clinically relevant, ESBL-producing K. pneumoniae ST307 and E. coli ST38 clonal lineages in an urban West African rat population. The human community is likely

    The study objective was to develop an open-source replicate of a cost-effectiveness model developed by National Institute for Health and Care (NICE) in order to explore uncertainties in health economic modeling of novel pharmacological neuropathic pain treatments. The NICE model, consisting of a decision tree with branches for discrete levels of pain relief and adverse event (AE) severities, was replicated using R and used to compare a hypothetical neuropathic pain drug to pregabalin. Model parameters were sourced from NICE's clinical guidelines and associated with probability distributions to account for underlying uncertainty. A simulation-based scenario analysis was conducted to assess how uncertainty in efficacy and AEs affected the net monetary benefit (NMB) for the hypothetical treatment at a cost-effectiveness threshold of £20,000 per QALY. Relative to pregabalin, an increase in efficacy was associated with greater NMB than an improvement in tolerability. A greater NMB was observed when efficacy was marginally higher than that of pregabalin while maintaining the same level of AEs than when efficacy was equivalent to pregabalin but with a more substantial reduction in AEs. In the latter scenario, the NMB was only positive at a low cost-effectiveness threshold. The replicate model shares the limitations described in the NICE guidelines. There is a lack of support in scientific literature for the assumption that increased efficacy is associated with a greater reduction in tolerability. The replicate model also included a single comparator, unlike the NICE model. Pain relief is a stronger driver of NMB than tolerability at a cost-effectiveness threshold of £20,000 per QALY. Health technology assessment decisions which are influenced by NICE's model may reward efficacy gains even if they are associated with more severe AEs. This contrasts with recommendations from clinical guidelines for neuropathic pain which place more equal weighting on improvements in

    Red cell (blood) transfusions are used in palliative care to manage patients with symptomatic anaemia or when patients have lost blood. We aimed to understand current blood transfusion practice among palliative medicine doctors and compare this with National Institute for Health and Care Excellence (NICE) guidance. NICE guidance advocates more restrictive transfusion practice but is based on clinical trials in non-palliative care contexts; the extent to which these findings should be applied to palliative care remains unclear. Four clinical vignettes of common clinical palliative care scenarios were developed. Members of the Association for Palliative Medicine were invited to complete the survey. Results were compared with acceptable responses based on current NICE recommendations and analysed to determine the influence of respondents' gender, experience or work setting. 27% of 1070 members responded. Overall, ideal or acceptable responses were selected by less than half of doctors to all four vignettes. Doctors were more liberal in prescribing blood transfusions than NICE guidance would advocate. Senior doctors were less likely to choose an acceptable response than junior colleagues. Palliative care practice is varied and not consistent with a restrictive blood transfusion policy. More recently trained doctors follow less liberal practices than senior colleagues. More direct evidence of benefits and harms of blood transfusion is needed in palliative care to inform practice. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    The laboratory detection of OXA-48-carbapenemase-producing Enterobacteriaceae is difficult, as minimum inhibition concentrations for carbapenems are often below the clinical breakpoint. In 2011, the Dutch national guideline for the detection of highly resistant micro-organisms was issued, which

    Primary aldosteronism (PA) due to aldosterone-producing adenoma (APA) is a form of surgically curable secondary hypertension, and distinguishing APA from idiopathic hyperaldosteronism (IHA) is important for treatment. We made a differential diagnosis between APA and IHA using imaging tests such as adrenal CT and MRI as well as adrenal venous sampling (AVS) in all 93 cases of PA presenting at our institutions over the last decade. We identified 27 patients with aldosterone-producing microadenoma (APmicroA), all of whom could be diagnosed by AVS but not by the imaging tests. Then, we compared the clinical and roent-genological findings of these 27 patients with those of 42 patients with aldosterone-producing macroadenoma (APmacroA) and of 24 patients with IHA. Using surgically removed adrenal tissues, histopathological examinations and immunohistochemical analyses of steroidogenic enzymes were conducted. The findings for APmicroA were similar to those for APmacroA, except with respect to the diameter of the adrenal adenomas. Endocrinological and roentgenological findings for APmicroA were similar to those for IHA, but not to those for APmacroA. The rate of cure of hypertension was much greater in patients with APmicroA than in patients with APmacroA after the unilateral adrenalectomy (odds ratio, 4.0; p=0.028). In conclusion, it is important to accurately diagnose APmicroA, in which the laterality of the hyperproduction of aldosterone is only detectable by AVS, and to treat these patients by unilateral adrenalectomy in order to avoid long-term medical treatment and prevent hypertensive vascular complications.

    Nothing is known about the epidemiology and resistance mechanisms of extended-spectrum ß-lactamase-producing Enterobacteriaceae (ESBL-PE) in Burkina Faso. The objective of this study was to determine ESBL-PE prevalence and to characterize ESBL genes in Burkina Faso. During 2 months (June-July 2014), 1602 clinical samples were sent for bacteriologic investigations to the microbiology laboratories of the tree main hospitals of Burkina Faso. Isolates were identified by mass spectrometry using a matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) BioTyper. Antibiotic susceptibility was tested using the disk diffusion method on Müller-Hinton agar. The different ESBL genes in potential ESBL-producing isolates were detected by PCR and double stranded DNA sequencing. Escherichia coli phylogenetic groups were determined using a PCR-based method. ESBL-PE frequency was 58 % (179 strains among the 308 Enterobacteriaceae isolates identified in the collected samples; 45 % in outpatients and 70 % in hospitalized patients). The CTX-M-1 group was dominant (94 %, CTX-M-15 enzyme), followed by the CTX-M-9 group (4 %). ESBL producers were more often found in E. coli (67.5 %) and Klebsiella pneumoniae (26 %) isolates. E. coli isolates (n = 202; 60 % of all Enterobacteriaceae samples) were distributed in eight phylogenetic groups (A = 49, B1 = 15, B2 = 43, C = 22, Clade I = 7, D = 37, F = 13 and 16 unknown); 22 strains belonged to the sequence type ST131. No association between a specific strain and ESBL production was detected. This report shows the alarming spread of ESBL genes in Burkina Faso. Public health efforts should focus on education (population and healthcare professionals), surveillance and promotion of correct and restricted antibiotic use to limit their dissemination.

    From the perspective of a pilot clinical gene therapy trial for Wiskott-Aldrich syndrome (WAS), we implemented a process to produce a lentiviral vector under good manufacturing practices (GMP). The process is based on the transient transfection of 293T cells in Cell Factory stacks, scaled up to harvest 50 liters of viral stock per batch, followed by purification of the vesicular stomatitis virus glycoprotein-pseudotyped particles through several membrane-based and chromatographic steps. The process leads to a 200-fold volume concentration and an approximately 3-log reduction in protein and DNA contaminants. An average yield of 13% of infectious particles was obtained in six full-scale preparations. The final product contained low levels of contaminants such as simian virus 40 large T antigen or E1A sequences originating from producer cells. Titers as high as 2 × 10(9) infectious particles per milliliter were obtained, generating up to 6 × 10(11) infectious particles per batch. The purified WAS vector was biologically active, efficiently expressing the genetic insert in WAS protein-deficient B cell lines and transducing CD34(+) cells. The vector introduced 0.3-1 vector copy per cell on average in CD34(+) cells when used at the concentration of 10(8) infectious particles per milliliter, which is comparable to preclinical preparations. There was no evidence of cellular toxicity. These results show the implementation of large-scale GMP production, purification, and control of advanced HIV-1-derived lentiviral technology. Results obtained with the WAS vector provide the initial manufacturing and quality control benchmarking that should be helpful to further development and clinical applications.

    For a doctor to provide medical care with competence, he must not only have knowledge but must also be able to translate that knowledge into action. It is his competence in clinical skills that will enable him to practice safely and effectively in the real world. To ensure acquisition of clinical skills, medical teachers must adopt teaching methods that prioritise observation, practice, feedback; and more practice. We try to elucidate the meaning of clinical skills, the challenges inherent in clinical skills training in India, training models that have shown success in practice and can be adopted in the Indian context, and various techniques to enhance skill-training, including the giving of feedback, which is a critically important component of skills development.

    Full Text Available Different indirect restorations to replace a single missing tooth in the posterior region are available in dentistry: traditional full-coverage fixed dental prostheses (FDPs, implant-supported crowns (ISC, and inlay-retained FDPs (IRFDP. Resin bonded FDPs represent a minimally invasive procedure; preexisting fillings can minimize tooth structure removal and give retention to the IRFDP, transforming it into an ultraconservative option. New high strength zirconia ceramics, with their stiffness and high mechanical properties, could be considered a right choice for an IRFDP rehabilitation. The case report presented describes an IRFDP treatment using a CAD/CAM monolithic zirconia IRFDP; clinical and laboratory steps are illustrated, according to the most recent scientific protocols. Adhesive procedures are focused on the Y-TZP and tooth substrate conditioning methods. Nice esthetic and functional integration of indirect restoration at two-year follow-up confirmed the success of this conservative approach.

    Full Text Available Background and Objectives: AmpC beta-lactamases are among cephalosporinases encoded on the chromosomes of many Enterobacteriaceae. In many bacteria, induction of AmpC enzymes can be made at a very high level by numerous mutations. In this study, the prevalence of chromosomal AmpC genes, was investigated in the isolates of Pseudomonas aeruginosa isolated from teaching hospitals in Zahedan city in 2015. Methods: In this descriptive cross-sectional study, 100 P. aeruginosa isolates were isolated from 391 clinical samples using biochemical and conventional methods. cefoxitin (30μg disk diffusion method was used to isolate AmpC-producing strains, and multiplex PCR was used to identify chromosomal AmpC genes. ESBL containing strains was assessed using ceftazidime (30μg and cefotaxime/clavulanic acid (30μg/10μg disk diffusion tests. Data analysis was performed using χ2 test. Results: In primary phenotypic screening, out of 100 P. aeruginosa isolated, 88 isolates were ESBL producers and 20 isolates (20% were AmpC beta-lactamase producers. Among 20 phenotypically identified AmpC producing isolates, 19 isolates (95% had FOX gene, 7 isolates (35% had EBC gene, 4 isolates (20% had ACC gene, and 15 isolates isolates (75% had DHA gene, which were detected by multiPlex PCR assay. Conclusion: The results of the present study indicated that the presence of AmpC leads to resistance of bacteria to many cephalosporins. Also, use of multiplex PCR yields the best results in the group identification of these genes.

    A two-dimensional clinical intravenous coronary angiography system, comprising a large-size View area produced by asymmetrical reflection from a silicon crystal using intense synchrotron radiation from a multipole wiggler and a two-dimensional detector with an image intensifier, has been completed. An advantage of the imaging system is that two-dimensional dynamic imaging of the cardiovascular system can be achieved due to its two-dimensional radiation field. This world-first two-dimensional system has been successfully adapted to clinical applications. Details of the imaging system are described in this paper

    A two-dimensional clinical intravenous coronary angiography system, comprising a large-size View area produced by asymmetrical reflection from a silicon crystal using intense synchrotron radiation from a multipole wiggler and a two-dimensional detector with an image intensifier, has been completed. An advantage of the imaging system is that two-dimensional dynamic imaging of the cardiovascular system can be achieved due to its two-dimensional radiation field. This world-first two-dimensional system has been successfully adapted to clinical applications. Details of the imaging system are described in this paper. 18 refs.

    We investigated the concentrations of degraded sevoflurane Compound A during low-flow anesthesia with four carbon dioxide (CO(2)) absorbents. The concentrations of Compound A, obtained from the inspiratory limb of the circle system, were measured by using a gas chromatograph. In the groups administered 2 L/min fresh gas flow with 1% sevoflurane, when the conventional CO(2) absorbents, Wakolime(TM) (Wako, Tokyo, Japan) and Drägersorb(TM) (Dräger, Lübeck, Germany), were used, the concentrations of Compound A increased steadily from a baseline to 14.3 ppm (mean) and 13.2 ppm, respectively, at 2 h after exposure to sevoflurane. In contrast, when the other novel types of absorbents containing decreased or no potassium hydroxide/sodium hydroxide, Medisorb(TM) (Datex-Ohmeda, Louisville, CO) and Amsorb(TM) (Armstrong, Coleraine, Northern Ireland), were used, Compound A remained at baseline (potassium hydroxide/sodium hydroxide produce much larger concentrations of Compound A from sevoflurane in clinical practice. An absorbent containing neither potassium hydroxide nor sodium hydroxide produces the smallest concentrations of Compound A.

  15. Traumatic brain injury produced by exposure to blasts, a critical problem in current wars: biomarkers, clinical studies, and animal models

    Traumatic brain injury (TBI) resulting from exposure to blast energy released by Improvised Explosive Devices (IEDs) has been recognized as the "signature injury" of Operation Iraqi Freedom and Operation Enduring Freedom. Repeated exposure to mild blasts may produce subtle deficits that are difficult to detect and quantify. Several techniques have been used to detect subtle brain dysfunction including neuropsychological assessments, computerized function testing and neuroimaging. Another approach is based on measurement of biologic substances (e.g. proteins) that are released into the body after a TBI. Recent studies measuring biomarkers in CSF and serum from patients with severe TBI have demonstrated the diagnostic, prognostic, and monitoring potential. Advancement of the field will require 1) biochemical mining for new biomarker candidates, 2) clinical validation of utility, 3) technical advances for more sensitive, portable detectors, 4) novel statistical approach to evaluate multiple biomarkers, and 5) commercialization. Animal models have been developed to simulate elements of blast-relevant TBI including gas-driven shock tubes to generate pressure waves similar to those produced by explosives. These models can reproduce hallmark clinical neuropathological responses such as neuronal degeneration and inflammation, as well as behavioral impairments. An important application of these models is to screen novel therapies and conduct proteomic, genomic, and lipodomic studies to mine for new biomarker candidates specific to blast relevant TBI.

    In order to establish PET diagnosis as a routine clinical tool, manufacture's compliance with regulations under the Good Manufacturing Practice (GMP) principle for PET radiopharmaceuticals is necessary. For this purpose, the Sub-committee on Medical Application of Positron Emitting Radionuclides, Medical Science and Pharmaceutical Committee of Japan Radioisotopes Association has proposed 'Standards for Compounds Labeled with Emitting Radionuclides Approved as Established Techniques for Medical Use'. This guideline includes the general notices, general rules for preparations, general tests for the quality control, quality of each PET agents, guideline for manufacturing environment and manufacturing process at manufacturing facilities of PET agents. Each facility should have a committee and establish an internal system to account for manufacturing compounds labeled with positron emitting radionuclides produced in the facility, and compile standards by referring to the 'Established Standard Techniques of Labeling Compounds with Emitting Radionuclides for use as Radiopharmaceuticals: approved by the Subcommittee on Medical Application of Cyclotron-Produced Radionuclides (revised in 2009)', in order to maintain the quality of radiopharmaceuticals.

    Full Text Available Time from symptomatic presentation to cancer diagnosis (diagnostic interval is an important, and modifiable, part of the patient's cancer pathway, and can be affected by various factors such as age, gender and type of presenting symptoms. The aim of this study was to quantify the relationships of diagnostic interval with these variables in 15 cancers diagnosed between 2007 and 2010 using routinely collected data from the Clinical Practice Research Datalink (CPRD in the UK.Symptom lists for each cancer were prepared from the literature and by consensus amongst the clinician researchers, which were then categorised into either NICE qualifying (NICE or not (non-NICE based on NICE Urgent Referral Guidelines for Suspected Cancer criteria. Multivariable linear regression models were fitted to examine the relationship between diagnostic interval (outcome and the predictors: age, gender and symptom type.18,618 newly diagnosed cancer patients aged ≥40 who had a recorded symptom in the preceding year were included in the analysis. Mean diagnostic interval was greater for older patients in four disease sites (difference in days per 10 year increase in age; 95% CI: bladder (10.3; 5.5 to 15.1; P<0.001, kidney (11.0; 3.4 to 18.6; P=0.004, leukaemia (18.5; 8.8 to 28.1; P<0.001 and lung (10.1; 6.7 to 13.4; P<0.001. There was also evidence of longer diagnostic interval in older patients with colorectal cancer (P<0.001. However, we found that mean diagnostic interval was shorter with increasing age in two cancers: gastric (-5.9; -11.7 to -0.2; P=0.04 and pancreatic (-6.0; -11.2 to -0.7; P=0.03. Diagnostic interval was longer for females in six of the gender non-specific cancers (mean difference in days; 95% CI: bladder (12.2; 0.8 to 23.6; P=0.04, colorectal (10.4; 4.3 to 16.5; P=0.001, gastric (14.3; 1.1 to 27.6; P=0.03, head and neck (31.3; 6.2 to 56.5; P=0.02, lung (8.0; 1.2 to 14.9; P=0.02, and lymphoma (19.2; 3.8 to 34.7; P=0.01.

    Full Text Available Pranabashis Haldar Respiratory Biomedical Research Unit, Glenfield Hospital, University of Leicester, Leicester, UK Abstract: Mepolizumab (Nucala® is an effective and specific anti-eosinophil molecular therapy that has recently been approved as add-on therapy for the management of severe eosinophilic asthma by the US Food and Drug Administration (FDA, European Medicines Agency (EMA; European Union and more recently National Institute for Health and Care Excellence (NICE; UK. It is one of several molecular therapies in development for this indication and is illustrative of the strategic trajectory for pharmaceutical drug development taken over the past decade in several disease areas. Molecular therapies offer the prospect of improved specificity and effectiveness of biological effect. However, this necessitates a clear understanding of the underlying mechanistic pathways underpinning pathological processes, to inform drug development that yields novel more efficacious treatment options with a better clinical profile than existing agents. For the first time, utilization of molecular therapies in clinical trials is providing a novel in vivo model to characterize the association between specific pathways and clinical disease expression. It is increasingly recognized that asthma exhibits both clinical and pathological heterogeneity. It follows that a one-size-fits-all approach will not be appropriate and cost-effectiveness may only be achieved by identifying responder subgroups. This so-called personalized approach to therapy is being supported by the parallel development of companion biomarkers for clinical application. In this review, the author summarizes the clinical studies, their interpretation and the lessons learnt with mepolizumab that have informed our understanding of the approach to personalized molecular therapy in asthma.

    We investigated the effects of a diet low in fermentable oligo-, di-, and monosaccharides and polyols (FODMAPs) vs traditional dietary recommendations on health-related quality of life (QOL), anxiety and depression, work productivity, and sleep quality in patients with irritable bowel syndrome and diarrhea (IBS-D). We conducted a prospective, single-center, single-blind trial of 92 adult patients with IBS-D (65 women; median age, 42.6 years) randomly assigned to groups placed on a diet low in FODMAPs or a modified diet recommended by the National Institute for Health and Care Excellence (mNICE) for 4 weeks. IBS-associated QOL (IBS-QOL), psychosocial distress (based on the Hospital Anxiety and Depression Scale), work productivity (based on the Work Productivity and Activity Impairment), and sleep quality were assessed before and after diet periods. Eighty-four patients completed the study (45 in the low-FODMAP group and 39 in the mNICE group). At 4 weeks, patients on the diet low in FODMAPs had a larger mean increase in IBS-QOL score than did patients on the mNICE diet (15.0 vs 5.0; 95% CI, -17.4 to -4.3). A significantly higher proportion of patients in the low-FODMAP diet group had a meaningful clinical response, based on IBS-QOL score, than in the mNICE group (52% vs 21%; 95% CI, -0.52 to -0.08). Anxiety scores decreased in the low-FODMAP diet group compared with the mNICE group (95% CI, 0.46-2.80). Activity impairment was significantly reduced with the low-FODMAP diet (-22.89) compared with the mNICE diet (-9.44; 95% CI, 2.72-24.20). In a randomized, controlled trial, a diet low in FODMAPs led to significantly greater improvements in health-related QOL, anxiety, and activity impairment compared with a diet based on traditional recommendations for patients with IBS-D.

    SPHEREx, a mission in NASA's Medium Explorer (MIDEX) program that was selected for a competitive Phase A study in August 2017, is an all-sky survey satellite designed to address all three science goals of NASA's Astrophysics Division. SPHEREx is a wide-field spectral imager, and it would produce the first all-sky near-infrared spectral survey, using a passively cooled telescope with a wide field-of-view for large mapping speed. The SPHEREx spectra would have resolving power R=41 at wavelengths from 0.75 to 4.2um, and R=135 from 4.2 to 5um. The spectra resolution is provided by Linear Variable Filters placed directly over the four SPHEREx H2RG detector arrays. SPHEREx would be sensitive enough to obtain spectra of essentially all near-infrared sources from the WISE survey. During its two-year mission, SPHEREx, to be launched in 2022, would produce four complete all-sky spectral maps that would serve as a rich archive for the astronomy community.SPHEREx would be tremendously synergistic with numerous other missions and facilities [NASA and non-NASA] which will be operating in the coming decade. SPHEREx observations could pick out the most promising and exciting targets for investigation from JWST. From the opposite perspective, SPHEREx statistical samples could be used to refine the conclusions derived from JWST’s indepth studies of a few members of an interesting class of objects. SPHEREx and GAIA spectrophotometry, incorporating photometry from WISE and GALEX as well as GAIA astrometry, could lead to the determination of the radii of main sequence stars, and their transiting exoplanets discovered by TESS, with 1% accuracy. SPHEREx low redshift spectra of millions of galaxies could be used to validate and calibrate the photometric nredshift scale being adopted by WFIRST and Euclid, improving the precision of the dark energy measures being returned by those missions. The poster will briefly address SPHEREx synergisms with these and other missions ranging from LSST

    Celecoxib for the treatment of pain resulting from osteoarthritis (OA) was reviewed by the Tandvårds- och läkemedelsförmånsverket-Dental and Pharmaceutical Benefits Board (TLV) in Sweden in late 2010. This study aimed to evaluate the incremental cost-effectiveness ratio (ICER) of celecoxib plus a proton pump inhibitor (PPI) compared to diclofenac plus a PPI in a Swedish setting. The National Institute for Health and Care Excellence (NICE) in the UK developed a health economic model as part of their 2008 assessment of treatments for OA. In this analysis, the model was reconstructed and adapted to a Swedish perspective. Drug costs were updated using the TLV database. Adverse event costs were calculated using the regional price list of Southern Sweden and the standard treatment guidelines from the county council of Stockholm. Costs for treating cardiovascular (CV) events were taken from the Swedish DRG codes and the literature. Over a patient's lifetime treatment with celecoxib plus a PPI was associated with a quality-adjusted life year (QALY) gain of 0.006 per patient when compared to diclofenac plus a PPI. There was an increase in discounted costs of 529 kr per patient, which resulted in an incremental cost-effectiveness ratio (ICER) of 82,313 kr ($12,141). Sensitivity analysis showed that treatment was more cost effective in patients with an increased risk of bleeding or gastrointestinal (GI) complications. The results suggest that celecoxib plus a PPI is a cost effective treatment for OA when compared to diclofenac plus a PPI. Treatment is shown to be more cost effective in Sweden for patients with a high risk of bleeding or GI complications. It was in this population that the TLV gave a positive recommendation. There are known limitations on efficacy in the original NICE model.

    Background: Pseudomonas aeruginosa is one of the most common pathogens causing infections in burns, and shows increasing resistance to β-lactam antibiotics by producing different classes of beta-lactamases. It is also not unusual to find a single isolate that expresses multiple β-lactamase enzymes, further complicating the treatment options. Thus, in this study, we aimed to determine the coexistence of different beta-lactamase enzymes in clinical isolates of P. aeruginosa in the burn ward. Ma...

    To qualitatively and quantitatively identify the level of agreement between the clinical staff of a quaternary care hospital and the National Institute for Health and Care Excellence (NICE) "do not do" recommendations, and to submit a strategic alternative for effective implementation. An ad hoc form was designed to evaluate level of clinical disagreement from the experience and knowledge of the clinical staff, as well as the applicability, usefulness, effectivity and efficiency of all the NICE "do not do" recommendations that had been published up to June 2012, checking their stability up to the July 2014 update. Description of the process of design and implementation of the strategic alternative to improve compliance is presented. The great majority (90%) of Clinical Unit directors agree with the NICE recommendations, with 64% finding them useful or very useful, 52% finding them applicable, and 32% and 34% thinking they are of high effectivity and efficiency, respectively. However, 20% of the efficient ones are not being applied. Moreover, knowledge discordances that might lead to clinical disagreements were detected. A strategic intervention, combining culture and incentives for good clinical practices, has been implemented. The improvement in the use of the good clinical practice recommendations is directly related to the agreement of its definition and evidence. An evaluation strategy of its application by the health professionals is essential to achieve an impact in avoidable costs. Moreover, to control for harmful effects of the economic impact on patient safety, it will be necessary to simultaneously evaluate clinical/health outcome indicators tightly linked to the applied recommendations.

    Chronic inflammation in haemodialysis (HD) patients indicates a poor prognosis. However, therapeutic approaches are limited. Hydrogen gas (H(2)) ameliorates oxidative and inflammatory injuries to organs in animal models. We developed an HD system using a dialysis solution with high levels of dissolved H(2) and examined the clinical effects. Dialysis solution with H(2) (average of 48 ppb) was produced by mixing dialysate concentrates and reverse osmosis water containing dissolved H(2) generated by a water electrolysis technique. Subjects comprised 21 stable patients on standard HD who were switched to the test HD for 6 months at three sessions a week. During the study period, no adverse clinical signs or symptoms were observed. A significant decrease in systolic blood pressure (SBP) before and after dialysis was observed during the study, and a significant number of patients achieved SBP <140 mmHg after HD (baseline, 21%; 6 months, 62%; P < 0.05). Changes in dialysis parameters were minimal, while significant decreases in levels of plasma monocyte chemoattractant protein 1 (P < 0.01) and myeloperoxidase (P < 0.05) were identified. Adding H(2) to haemodialysis solutions ameliorated inflammatory reactions and improved BP control. This system could offer a novel therapeutic option for control of uraemia.

    Colombia is developing multiple national practice guidelines from a range of diseases. Clinical practice guidelines represent a very useful tool to be able to take decision over a patient care that is widely available for the clinician. In psychiatry there are a good number of international clinical guidelines for the treatment of schizophrenia nevertheless there is no article that evaluate them scientifically In the settings of developing a Colombian schizophrenia practice guideline, a systematic search was performed in multiple databases and the results were then evaluated by two trained persons. We present the results globally and by domains. We found 164 matches for possible guidelines. After screening 7 guidelines were evaluated with the AGREE II instrument. Globally and by the different domains, the National Institute for Health and Care Excellence (NICE) was the guideline that got the best score. From the guidelines that were reviewed, 4 were from Europe and only 2 were from Latin America. None of the guidelines used GRADE methodology for the recommendations. The diversity of the schizophrenia treatment guidelines does not allow an easy adoption of the recommendation by a psychiatrist in Colombia. Copyright © 2014 Asociación Colombiana de Psiquiatría.

    UK National Institute of Clinical Excellence (NICE) guidelines on surgical management of otitis media with effusion (OME) in children call for an initial 3 month period of observation, with ventilation tube (VT) insertion considered for children with persistent bilateral OME with a hearing level in better ear of 25-30 dB HL or worse ("core criteria"), or for children not meeting those audiologic criteria but when OME has significant impact on developmental, social or educational status (exceptional circumstances). We aimed to establish whether guidelines are followed and whether they have changed clinical practice. Retrospective case-notes review in five different centres, analysing practice in accordance with guidelines in all children having first VT insertion before (July-December 06) and after (July-December 08) guidelines introduction. Records of 319 children were studied, 173 before and 146 after guidelines introduction. There were no significant differences in practice according to guidelines before and after their introduction with respect to having 2 audiograms 3 months apart (57.8 vs. 54.8%), OME persisting at least 3 months (94.8 vs. 92.5%), or fulfilment of the 25 dB audiometric criteria (68.2 vs. 61.0%). Practice in accordance with the core criteria fell significantly from 43.9 to 32.2% (Chi squared p=0.032). However, if the exceptional cases were included there was no significant difference (85.5 vs. 87.0%), as the proportion of exceptional cases rose from 48.3 to 62.2% (Chi squared p=0.021). This study shows that 87.0% of children have VTs inserted in accordance with NICE guidelines providing exceptional cases are included, but only 32.2% comply with the core criteria. A significant number have surgery due to the invoking of exceptional criteria, suggesting that clinicians are personalising the treatment to each individual child.

Thirty-one species of aquatic molluscs (19 gastropods, 12 bivalves representing 40% of freshwater molluscan fauna of the Czech Republic were found at 15 sites. Differences of molluscan assemblages upstream and downstream of Tábor town were probably caused by different characters of the watercourse. The occurrence of rare bivalve Pseudanodonta complanata was confirmed. On the other hand, two non-native species Physella acuta and Sinanodonta woodiana were recorded. The research was preferentially focused on the population of the endangered bivalve Unio crassus. Its occurrence was confirmed at 8 from 15 sites under study but altogether only 31 individuals were found. Less than four specimens were found at particular sites but one.

    In a historical cohort of children with a urinary tract infection (UTI) who had already undergone all the imaging procedures, the aim was to determine renal tract abnormalities which would have been missed had we implemented the new guidelines from the National Institute for Health and Care Excellence in the United Kingdom (NICE) or the American Academy of Pediatrics (AAP). After a UTI episode, forty-three children (28 females, 65%) aged between 2 months and 2 years presenting at two general hospitals with a febrile UTI before 2008 underwent all the recommended imaging studies predating the new guidelines. Hydronephrosis was defined and graded according to the Society for Fetal Urology (SFU) classification. Hydronephrosis grade II (mild pelvicalyceal dilatation), grade III (moderate dilatation), and grade IV (gross dilatation with thinning of the renal cortex), duplication, vesicoureteral reflux (VUR) grade II and above, renal scarring and reduced renal uptake (<45%) on technetium-99m-labeled dimercaptosuccinic acid (DMSA) scintigraphy were considered significant abnormalities. We calculated the proportion of abnormalities which would have been missed had the new guidelines been used instead. The median of age was 7.6 months (mean 8.7, range 2-24 months), with the majority (n = 37, 86%) being under 1 year of age. Ultrasound (US) showed hydronephrosis in 14 (32%), all grade II. A voiding cystourethrogram (VCUG) was performed in all and showed VUR ≥ grade II in 16 (37%), including eight children (19%) where it was bilateral. DMSA scan showed scarring in 25 children (58%) of whom 11 (26%) had bilateral scars. Reduced differential renal uptake was present in 10 children (23%). Of the 29 children with normal US, 18 (62%) had renal scarring and nine (31%) had VUR ≥ grade II. The NICE guidelines would have missed 63% of the children with VUR ≥ grade II, including a high proportion of grades IV and V VUR, 44% of the children with renal scarring, and 20% of the

    Full Text Available We present the clinical case of a patient who was admitted with an onset of diabetes mellitus (DM with associated ketosis and whose clinical, hormonal, and radiological evolution revealed the presence of primary hyperparathyroidism, pancreatic neuroendocrine tumor, and GH-producing pituitary macroadenoma in the context of multiple endocrine neoplasia type 1 (MEN1. DM is relatively common in cases of acromegaly, but it is not generally associated with ketosis. Simultaneously, the patient presented a meningioma, which is associated with pituitary macroadenoma only in extremely rare cases.

    Clinical and pathological studies of the peripheral and central nervous system degeneration (distal dying-back axonopathy) in humans and experimental animals produced by acrylamide monomer and certain hydrocarbon compounds are summarized. The human distal axonopathies include: many of the naturally occurring, genetically determined system disorders/ certain nutritional disorders/ uremic neuropathy/ the neuropathies associated with some malignancies/ and the toxic neuropathies induced by industrial chemicals. The irreversible, subclinical, and clinical effects of distal axonopathies on the human central nervous system are examined. A morphological rationale for previously enigmatic clinical phenomena in the human toxic neuropathies is presented. Neuropathology is potentially useful in the screening of chemicals for neurotoxicity. (7 photos, 24 references)

    To investigate the occurrence and characteristics of ESBL/AmpC-producing Escherichia coli in faecal samples from horses at one equine clinic in the Netherlands. A total of 91 horses, including residents and patients, were sampled. ESBL/AmpC-producing E. coli were identified by a combination disc diffusion test. Phylogenetic groups and MLST were determined. ESBL/AmpC genes were analysed using PCR and sequencing. Plasmids were characterized by transformation and PCR-based replicon typing. Subtyping of plasmids was done by plasmid MLST. At least one E. coli isolate with a confirmed ESBL/AmpC gene was found in samples from 76 horses (84%). Although phylogenetic group B1 E. coli bla CTX-M-1 predominated, a diverse E. coli population was found, indicating that clonal nosocomial spread was not the only reason for the high occurrence found. MLST analysis revealed the presence of 47 E. coli STs, organized in four clusters of genetically related strains. ST10, ST641, ST1079 and ST1250 were most commonly found. With regard to the genes, bla CTX-M-1 was most prevalent ( n  =   91), followed by bla CTX-M-2 ( n  =   26). The most frequently found plasmid type was IncHI1, but plasmids belonging to the IncF, IncI1 and IncN groups were also identified. A high occurrence of ESBL-producing E. coli in faecal samples was found among horses in an equine clinic and the variety of STs, ESBL genes and plasmid types suggests nosocomial transmission. ESBL E. coli can cause difficult-to-treat infections in horses and prudent use of antimicrobials is warranted. A further assessment of the risks of transmission to persons in close contact with horses, such as caretakers or veterinarians, is crucial. © The Author 2017.

    Pregnancy-associated glycoproteins (PAG) are produced by the ruminant placenta and secreted into the maternal circulation throughout pregnancy. The extent to which circulating PAG concentrations predict pregnancy outcomes was examined herein. Also, associations between circulating PAG concentrations and various production parameters and clinical diseases were evaluated. Lactating primiparous and multiparous Holstein cows (n=345) were bred via timed artificial insemination using a standard Ovsynch protocol. Pregnancy was diagnosed by transrectal ultrasonography at d 32, 46, and 74 of gestation. Blood was harvested at d 32 to determine plasma concentrations of PAG and progesterone. Cows pregnant at d 32 that subsequently lost their pregnancy at d 46 and 74 had reduced PAG concentrations. Both artificial insemination service number and parity were associated with plasma PAG concentrations. Concentration of PAG in plasma was greater for cows pregnant from their second or later breeding than those pregnant from the first breeding postpartum, and was increased for primiparous compared with multiparous. In addition, cows with greater milk yield had increased plasma PAG concentrations. No association was detected between body condition score and plasma PAG concentrations. Cows that experienced clinical metritis, metabolic problems, or left displacement abomasum in the early postpartum period preceding breeding had greater plasma PAG concentrations than cows not experiencing these clinical diseases. Also, cows with multiple clinical diseases had increased odds of pregnancy loss when compared with cows not experiencing clinical diseases. Odds ratio testing detected a tendency in the relationship between reduced milk yield and increased pregnancy loss. Collectively, these associations illustrate one feature of the early developing placenta that may predict pregnancy outcomes in dairy cattle. It is unclear if plasma PAG are actively involved with mediating pregnancy outcomes

    The spread of carbapenemase-producing Gram-negative rods is an emerging global problem. Although most infections due to carbapenemase producers are limited to healthcare institutions, reports of the occurrence of clinically relevant carbapenemase producers in sewage and polluted rivers are increasingly frequent. Polluted rivers flowing to oceans may contaminate coastal waters with multidrug-resistant bacteria, potentially threatening the safety of recreational activities in these locations. Here we assessed the occurrence of carbapenemase producers in water from touristic beaches located in Rio de Janeiro, Brazil, showing distinct pollution patterns. The presence of enterobacteria was noted, including the predominantly environmental genus Kluyvera spp., producing either Klebsiella pneumoniae carbapenemase (KPC) or Guyana extended-spectrum (GES)-type carbapenemases and often associated with quinolone resistance determinants. An Aeromonas sp. harbouring blaKPC and qnrS was also observed. These findings strengthen the role of aquatic matrices as reservoirs and vectors of clinically relevant antimicrobial-resistant bacteria, with potential to favour the spread of these resistance threats throughout the community.

    Plantaricins, one of bacteriocin produced by Lactobacillus plantarum, are already known to have activities against several pathogenic bacterium. L. plantarum U10 isolated from "tempoyak," an Indonesian fermented food, produced one kind of plantaricin designated as plantaricin W (plnW). The plnW is suggested as a putative membrane location of protein and has similar conserved motif which is important as immunity to bacteriocin itself. Thus, due to study about this plantaricin, several constructs have been cloned and protein was analyzed in Lactococcus lactis. In this study, plnW gene was successfully cloned into vector NICE system pNZ8148 and created the transformant named L. lactis NZ3900 pNZ8148-WU10. PlnW protein was 25.3 kDa in size. The concentration of expressed protein was significantly increased by 10 ng/mL nisin induction. Furthermore, PlnW exhibited protease activity with value of 2.22 ± 0.05 U/mL and specific activity about 1.65 ± 0.03 U/mg protein with 50 ng/mL nisin induction. Immunity study showed that the PlnW had immunity activity especially against plantaricin and rendered L. lactis recombinant an immunity broadly to other bacteriocins such as pediocin, fermentcin, and acidocin.

    Highlights: • Integrated approach to assess pollutant distribution in floodplain. • Natural background concentration is a function and not a value. • Concept of local enrichment factors based on local background functions. • Secondary pollution from transient fluvial deposits. - Abstract: Uranium mining and processing in the watershed of the Ploučnice River in the Czech Republic during a well-defined time interval (1969–1989) allowed for a study of pollutant fates in sediments of a meandering river that is otherwise in a nearly natural state. A considerable part of the primary pollution is present in hotspots in the floodplain 10–15 km downstream from the mining district. One of the hotspots was characterised using geoinformatic, geophysical and geochemical means. The floodplain geomorphology and architecture and river channel dynamics were studied to develop an understanding of the formation of the hotspot and evaluate further movement of pollutants in the river system. Local background functions (with Rb or Ti as a predictor) and local enrichment factors (LEFs) were obtained for Ba, Ni, Pb, U and Zn concentrations in unpolluted sediments from the deeper strata of the active floodplain, an abandoned floodplain and an ancient terrace. The most recent (2013) overbank fines in the study area are still considerably enriched in Ni, U and Zn (LEF 3, 6 and 8, respectively), and thus pollution by heavy metals several km downstream of the hotspots continuously increases even though the primary source of pollution was terminated more than 20 years ago. The onset of the primary pollution (the base of the polluted strata) is hence clearly identified in the distal floodplain sediments as persistent and a potentially isochronous pollution signal in the fluvial record, whereas a secondary pollution signal overwrites the expected “primary pollution climax” and “pollution improvement” signals. That inertia of the fluvial system can also be expected in other

    In recent years, sea-ice conditions in the Arctic Ocean changed substantially toward a younger and thinner sea-ice cover. To capture the scope of these changes and identify the differences between individual regions, in situ observations from expeditions are a valuable data source. We present a continuous time series of in situ measurements from the N-ICE2015 expedition from January to June 2015 in the Arctic Basin north of Svalbard, comprising snow buoy and ice mass balance buoy data and local and regional data gained from electromagnetic induction (EM) surveys and snow probe measurements from four distinct drifts. The observed mean snow depth of 0.53 m for April to early June is 73% above the average value of 0.30 m from historical and recent observations in this region, covering the years 1955-2017. The modal total ice and snow thicknesses, of 1.6 and 1.7 m measured with ground-based EM and airborne EM measurements in April, May, and June 2015, respectively, lie below the values ranging from 1.8 to 2.7 m, reported in historical observations from the same region and time of year. The thick snow cover slows thermodynamic growth of the underlying sea ice. In combination with a thin sea-ice cover this leads to an imbalance between snow and ice thickness, which causes widespread negative freeboard with subsequent flooding and a potential for snow-ice formation. With certainty, 29% of randomly located drill holes on level ice had negative freeboard.

    To evaluate the use of plasma Placental Growth Factor (PlGF), recommended by the recent NICE guidance, in women with suspected pre-eclampsia (PE) and/or fetal growth restriction (FGR). Non-randomised prospective clinical evaluation study in high-risk antenatal clinics in a tertiary maternity unit. PlGF testing was performed in addition to routine clinical assessment in 260 women >20 weeks' gestation with chronic disease (hypertension, renal disease ± diabetes) with a change in maternal condition or in women with suspected FGR to determine the impact on clinical management. Results were revealed and standardised care pathways followed. Outcome of pregnancies with a low PlGF (women had an adverse outcome (PE/birthweight women with PlGF 14 days. The PlGF result altered clinical management (surveillance or timing of birth) in 196/260 (75.4%) cases. Alternative PlGF thresholds did not significantly improve diagnostic performance. Our evaluation confirms the value of PlGF as a diagnostic tool for placental dysfunction. However, low PlGF in isolation should not trigger iatrogenic delivery. Further research linking placental pathology, maternal disease and maternal PlGF levels is urgently needed before this test can be implemented in routine clinical practice. Copyright © 2018.

    Infections caused by carbapenem-resistant Enterobacteriaceae are a public health problem associated with higher mortality rates, longer hospitalization and increased healthcare costs. We carried out a study to describe the characteristics of patients with carbapenemase-producing Enterobacteriaceae (CPE) and non-CPE bloodstream infection (BSI) from Latin American hospitals and to determine the clinical impact in terms of mortality and antibiotic therapy. Between July 2013 and November 2014, we conducted a multicenter observational study in 11 hospitals from 7 Latin American countries (Argentina, Colombia, Ecuador, Guatemala, Mexico, Peru, Venezuela). Patients with BSI caused by Enterobacteriaceae were included and classified either as CPE or non-CPE based on detection of blaKPC, blaVIM, blaIMP, blaNDM and blaOXA-48 by polymerase chain reaction. Enrolled subjects were followed until discharge or death. Demographic, microbiological and clinical characteristics were collected from medical records. Both descriptive and inferential statistics were used to analyze the information. A total of 255 patients with Enterobacteriaceae BSI were included; CPE were identified in 53 of them. In vitro non-susceptibility to all screened antibiotics was higher in the patients with CPE BSI, remaining colistin, tigecycline and amikacin as the most active drugs. Combination therapy was significantly more frequent in the CPE BSI group (p mortality was 37% (94/255). Overall and attributable mortality were significantly higher in patients with CPE BSI (p mortality. After multivariate adjustment, CPE BSI (adjusted odds ratio [aOR] 4; 95% confidence interval [CI] 1.7-9.5; p = 0.002) and critical illness (aOR 6.5; 95% CI 3.1-13.7; p mortality. This study provides valuable data on the clinical characteristics and mortality risk factors in patients with CPE BSI. We determined that CPE infection is an independent mortality predictor and thus Latin American hospitals should perform campaigns on

    Selby Edward B

    2007-06-01

    Full Text Available Abstract Background Infections caused by multiply drug resistant organisms such as extended spectrum beta-lactamase (ESBL-producing Escherichia coli and Klebsiella pneumoniae are increasing. Carbapenems (imipenem and meropenem are the antibiotics commonly used to treat these agents. There is limited clinical data regarding the efficacy of the newest carbapenem, ertapenem, against these organisms. Ertapenem susceptibility of ESBL-producing E. coli and K. pneumoniae clinical isolates were evaluated and compared to imipenem to determine if imipenem susceptibility could be used as a surrogate for ertapenem susceptibility. Methods 100 ESBL isolates (n = 34 E. coli and n = 66 K. pneumoniae collected from 2005–2006 clinical specimens at WRAMC were identified and tested for susceptibility by Vitek Legacy [bioMerieux, Durham, NC]. Ertapenem susceptibility was performed via epsilometer test (E-test [AB Biodisk, Solna, Sweden]. Results 100% of ESBL isolates tested were susceptible to ertapenem. 100% of the same isolates were also susceptible to imipenem. Conclusion These results, based on 100% susceptibility, suggest that ertapenem may be an alternative to other carbapenems for the treatment of infections caused by ESBL-producing E. coli and K. pneumoniae. Clinical outcomes studies are needed to determine if ertapenem is effective for the treatment of infection caused by these organisms. However, due to lack of resistant isolates, we are unable to conclude whether imipenem susceptibility accurately predicts ertapenem susceptibility.

    Although plant biotechnology has been widely investigated for the production of clinical-grade monoclonal antibodies, no antibody products derived from transgenic plants have yet been approved by pharmaceutical regulators for clinical testing. In the Pharma-Planta project, the HIV-neutralizing human monoclonal antibody 2G12 was expressed in transgenic tobacco (Nicotiana tabacum). The scientific, technical and regulatory demands of good manufacturing practice (GMP) were addressed by comprehensive molecular characterization of the transgene locus, confirmation of genetic and phenotypic stability over several generations of transgenic plants, and by establishing standard operating procedures for the creation of a master seed bank, plant cultivation, harvest, initial processing, downstream processing and purification. The project developed specifications for the plant-derived antibody (P2G12) as an active pharmaceutical ingredient (API) based on (i) the guidelines for the manufacture of monoclonal antibodies in cell culture systems; (ii) the draft European Medicines Agency Points to Consider document on quality requirements for APIs produced in transgenic plants; and (iii) de novo guidelines developed with European national regulators. From the resulting process, a GMP manufacturing authorization was issued by the competent authority in Germany for transgenic plant-derived monoclonal antibodies for use in a phase I clinical evaluation. Following preclinical evaluation and ethical approval, a clinical trial application was accepted by the UK national pharmaceutical regulator. A first-in-human, double-blind, placebo-controlled, randomized, dose-escalation phase I safety study of a single vaginal administration of P2G12 was carried out in healthy female subjects. The successful completion of the clinical trial marks a significant milestone in the commercial development of plant-derived pharmaceutical proteins. © 2015 Society for Experimental Biology, Association of

    Full Text Available Abstract For the protection of commercial interests, licensing bodies such as the EMA and health technology assessment institutions such as NICE restrict full access to unpublished evidence. Their respective policies on data transparency, however, lack a systematic account of (1 what kinds of commercial interests remain relevant after market approval has been granted, (2 what the specific types of public interest are that may override these commercial interests post approval, and, most importantly, (3 what criteria guide the trade-off between public interest and legitimate measures for the protection of commercial interest. Comparing potential commercial interests with seven specifications of relevant public interest reveals the lack of proportionality inherent in the current practices of EMA and NICE.

    2011-03-01

    Full Text Available Abstract Background Postnatal depression (PND can be experienced by 13% of women who give birth, and such women often exhibit disabling symptoms, which can have a negative effect on the mother and infant relationship, with significant consequences in terms of the child's later capacity for affect regulation. Research has shown that providing support to mothers experiencing PND can help reduce their depressive symptoms and improve their coping strategies. The Mums4Mums study aims to evaluate the impact of telephone peer-support for women experiencing PND. Methods/Design The study design adopts the MRC framework for the development and evaluation of complex interventions. Health visitors in Warwickshire and Coventry Primary Care Trusts are screening potential participants at the 8-week postnatal check using either the Edinburgh Postnatal Depression Scale (EPDS > = 10 or the three Whooley questions recommended by NICE (http://guidance.nice.org.uk/CG45. The Mums4Mums telephone support intervention is being delivered by trained peer-supporters over a period of four months. The primary outcome is depressive symptomatology as measured by the Edinburgh Postnatal Depression Scale. Secondary outcomes include mother-child interaction, dyadic adjustment, parenting sense of competence scale, and self-efficacy. Maternal perceptions of the telephone peer-support are being assessed using semi-structured interviews following the completion of the intervention. Discussion The proposed study will develop current innovative work in peer-led support interventions and telecare by applying existing expertise to a new domain (i.e. PND, testing the feasibility of a peer-led telephone intervention for mothers living with PND, and developing the relationship between the lay and clinical communities. The intervention will potentially benefit a significant number of patients and support a future application for a larger study to undertake a full evaluation of the clinical

    Cardiotocography (CTG) has disappointingly failed to show good predictability for fetal acidemia or neonatal outcomes in several large studies. A complete rethink of CTG interpretation will not be out of place. Fetal heart rate (FHR) decelerations are the most common deviations, benign as well as manifestation of impending fetal hypoxemia/acidemia, much more commonly than FHR baseline or variability. Their specific nomenclature is important (center-stage) because it provides the basic concepts and framework on which the complex "pattern recognition" of CTG interpretation by clinicians depends. Unfortunately, the discrimination of FHR decelerations seems to be muddled since the British obstetrics adopted the concept of vast majority of FHR decelerations being "variable" (cord-compression). With proliferation of confusing waveform criteria, "atypical variables" became the commonest cause of suspicious/pathological CTG. However, National Institute for Health and Care Excellence (NICE) (2014) had to disband the "typical" and "atypical" terminology because of flawed classifying criteria. This analytical review makes a strong case that there are major and fundamental framing and confirmation fallacies (not just biases) in interpretation of FHR decelerations by NICE (2014) and International Federation of Gynecology and Obstetrics (FIGO) (2015), probably the biggest in modern medicine. This "post-truth" approach is incompatible with scientific practice. Moreover, it amounts to setting oneself for failure. The inertia to change could be best described as "backfire effect". There is abundant evidence that head-compression (and other non-hypoxic mediators) causes rapid rather than shallow/gradual decelerations. Currently, the vast majority of decelerations are attributed to unproven cord compression underpinned by flawed disproven pathophysiological hypotheses. Their further discrimination based on abstract, random, trial and error criteria remains unresolved suggesting a

    The National Patient Safety Agency (2009) publication advising timely follow-up of patients with established glaucoma followed several reported instances of visual loss due to postponed appointments and patients lost to follow-up. The Royal College of Ophthalmologists Quality Standards Development Group stated that all hospital appointments should occur within 15% of the intended follow-up period. To determine whether: 1. Glaucoma follow-up appointments at a teaching hospital occur within the requested time 2. Appointments are requested at appropriate intervals based on the NICE Guidelines 3. The capacity of the glaucoma service is adequate Methods: A two-part audit was undertaken of 98 and 99 consecutive patients respectively attending specialist glaucoma clinics. In the first part, the reasons for delayed appointments were recorded. In the second part the requested follow-up was compared with NICE guidelines where applicable. Based on the findings, changes were implemented and a re-audit of 100 patients was carried out. The initial audit found that although clinical decisions regarding follow-up intervals were 100% compliant with NICE guidelines where applicable, 24% of appointments were delayed beyond 15% of the requested period, due to administrative errors and inadequate capacity, leading to significant clinical deterioration in two patients. Following the introduction of an electronic appointment tracker and increased clinical capacity created by extra clinics and clinicians, the re-audit found a marked decrease in the percentage of appointments being delayed (9%). This audit is a useful tool to evaluate glaucoma service provision, assist in resource planning for the service and bring about change in a non-confrontational way. It can be widely applied and adapted for use in other medical specialities.

    Suicide is the most serious complications of depression. It has high associated health costs and causes millions of deaths worldwide per year. Given its implications, it is important to know the factors that increase the risk of its occurrence and the most useful tools for addressing it. To identify the signs and symptoms that indicate an increased risk of suicide, and factors that increase the risk in patients diagnosed with depression. To establish the tools best fitted to identify suicide risk in people with depression. Clinical practice guidelines were developed, following those of the methodmethodological guidelines of the Ministry of Social Protection, to collect evidence and to adjust recommendations. Recommendations from the NICE90 and CANMAT guidelines were adopted and updated for questions found in these guidelines, while new recommendations were developed for questions not found in them. Basic points and recommendations are presented from a chapter of the clinical practice guidelines on depressive episodes and recurrent depressive disorder related to suicide risk assessment. Their corresponding recommendation levels are included. Copyright © 2013 Asociación Colombiana de Psiquiatría. Publicado por Elsevier España. All rights reserved.

    To report clinical outcomes of 125 I low-dose-rate prostate brachytherapy (LDR-PB) as monotherapy or combined with androgen-deprivation therapy (ADT) and/or external beam radiotherapy (EBRT) in high-risk localised prostate cancer. Analysis of clinical outcomes from a prospective cohort of patients treated with LDR-PB alone or combined treatment in a single institution. Men with a high risk of disease relapse were identified by the National Institute for Health and Care Excellence (NICE) criteria or by the National Comprehensive Cancer Network (NCCN) criteria. Relapse-free survival (RFS), overall survival (OS), prostate cancer-specific survival (PCSS), and metastases-free survival (MFS), were analysed together with patient-reported symptom scores and physician-reported adverse events. The NICE and NCCN criteria identified 267 and 202 high-risk patients, respectively. NICE-defined patients had significantly lower pre-treatment PSA levels, Gleason scores LDR-PB monotherapy. At 9 years after implantation RFS was 89% and 87% in the NICE and NCCN groups, respectively (log-rank P = 0.637), and OS 93% and 94%, respectively (log-rank P = 0.481). All of the survival estimates were similar between LDR-PB monotherapy and combined therapies. Cox proportional hazards regression confirmed RFS was similar between the treatment types. Treatment-related toxicity was also similar between the treatment methods. LDR-PB is effective at controlling localised prostate cancer in patients with a high risk of disease relapse. As the present study was not randomised, it is not possible to define those patients who need the addition of ADT and/or EBRT. However, the NICE criteria appear suitable to define treatment options where patients could benefit from LDR-PB as monotherapy or combined treatment. This choice should be discussed with the patient taking into account comorbidities and presence of multiple high-risk factors. © 2018 The Authors BJU International © 2018 BJU International

    2011-10-01

    The physiology and consequences of refeeding syndrome have long been recognised, although its management continues to be debated, despite the recommendations made by The National Institute for Health and Clinical Excellence (NICE) in their guideline 'Nutrition Support in Adults' (2006). The present study aims to assess current dietetic opinion and practice in this area, as well as whether the NICE recommendations have been adopted. An anonymous, self-completed Internet survey was designed investigating current practice and opinions on the NICE (2006) guidance on this subject. A link to the questionnaire was distributed with a covering letter via e-mail to the heads of department of National Health Service Trusts in the London region, UK, requesting that it be disseminated to all dietitians working with adults. After the closing date, all responses were collated and analysed. The survey elicited a 30.8% response rate. Some 89.8% of respondents have read the NICE guidance on Nutrition Support in Adults (2006) and 66.9% have changed their practice regarding refeeding syndrome management as a result. Sixty-two percent do not wait for biochemistry to normalise before commencing nutrition. Ninety-two percent of respondents completed the mini case studies indicating that current practice is inconsistent among dietitians. Neither NICE criteria for recognising patients at risk of refeeding, nor the recommended starting rates are universally followed. Seventy-five percent continue to supplement electrolytes reactively. Although limited by a small sample size, the findings of the present study suggest that dietetic practice regarding refeeding syndrome management remains inconsistent with the recommendations made by NICE, although some aspects have been adopted. © 2011 The Author.

  15. Diagnosis and management of ADHD: a new way forward?

    Science.gov (United States)

    Brimble, Mandy J

    2009-10-01

    Attention deficit hyperactivity disorder (ADHD) is a condition characterised by a persistent pattern of inattention or hyperactivity. The condition impacts on multiple aspects of an individual's life, as it can affect motor skills, social relationships, self-esteem and educational success. The diagnosis and management of this condition is of concern to healthcare professionals and is a topic often debated by the media. The most recent National Institute for Health and Clinical Excellence (NICE) guidance on diagnosing and managing ADHD in children, young people and adults has triggered a resurgence of this debate. The NICE guidance is particularly interesting because it states that behavioural therapies, rather than medications, should be the first-line treatment. While this apparent reversal in approach will be welcomed by some, this is an emotive issue and will no doubt also meet with strong opposition. This paper seeks to explore and discuss the existing evidence relating to medication versus behavioural therapies, and difficulties that may arise in implementing the latest NICE guidance.

    Several studies have evaluated the use of decompressive hemicraniectomy (DHC) in malignant middle cerebral artery infarction (MMCAI). In the United Kingdom, the National Institute for Health and Care Excellence (NICE) has set criteria for selection of patients for DHC in MMCAI. We set out to survey the attitudes and practice of neurosurgeons and stroke physicians within the United Kingdom towards DHC in MMCAI. An electronic survey of questions on management of MMCAI in various clinical scenarios was submitted to the academic committees of the Society of British Neurological Surgeons and the British Association of Stroke Physicians for approval before dissemination through the consultant members. Responses were collected over 2 months. A total of 78 responses, from 51 neurosurgeons and 27 stroke physicians, were included in final analysis. A total of 54% and 24% of all respondents would recommend DHC in patients aged 60-70 and 70-80 years, respectively; 60% would advocate surgery between 48 and 72 hours and 27% beyond 72 hours. A total of 36% indicated DHC with preoperative Glasgow Coma Scale 15/15. These findings do not conform to current NICE guidelines. Stroke physicians were statistically more likely to recommend DHC in patients older than 60 years (P = 0.032) and in those with dominant multiterritorial infarcts (P = 0.042) and accept a greater postoperative modified Rankin Scale (P = 0.034) compared with neurosurgeons. In view of evidence from recent trials and differences in NICE guidelines and current clinical practice within the United Kingdom, based on our survey results, it is important to reevaluate NICE guidelines.

    Full text: Extended spectrum β-lactamase is most commonly produced by strains of K.pneumoniae and E.coli, and TEM, SHV, CTX-M and AmpC types of the ESBLs are commonly spread among different nations. Previous investigators have already established that certain strains or ''epidemic clones'' of ESBL producing organisms spread within and also among hospitals. Although, some clones may disseminate regionally. Other authors emphasize the importance of plasmid transfer, rather than strain spread and plasmid encoding ESBL can transmit between different species of the family Enterobacteriaceae. The genes encoding these β-lactamases are often located on large plasmids that also encode genes for resistance to other antibiotics, including aminoglycosides, tetracycline, sulfonamides, trimethoprim and chloramphenicol. Furthermore, there is an increasing tendency for pathogens to produce multiple Β-lactamases. Some isolate of Klebsiella pneumoniae which is multiply resistant, expresses a minimum of five different β-lactamases, most of which are encoded on one large transferable plasmid. Materials and Methods: Nonrepetitive ESBL producing E. coli, K. pneumoniae and E.cloaceae isolates were collected in the bacteriology laboratory at Maternal and Child Research Institution, Ulaanbaatar (the biggest and central hospital facility for reproductive health service in Mongolia) in 2001, 2002, 2005, and 2006. Isolates were identified by conventional biochemical testing. Antimicrobial susceptibility were tested by disk diffusion test and MICs of some -lactams were determined alone or in combination with a fixed concentration of either clavulanic acid (2 μg/ml) according to the guideline of the National Committee for Clinical Laboratory Standards (NCCLS). ESBL production was screened using cefpodoxime disks and was confirmed by the double-disk synergy test. For detection of resistance transfer by conjugation, agar-mating technique was used with cultures of E.coli J53 Azir. PCRs with

    OXA-244 is a single-point-mutant derivative of OXA-48 displaying reduced carbapenemase activity. Here, we report the microbiological features of seven OXA-244-producing Escherichia coli isolates. Only one isolate grew on ChromID Carba Smart medium (bioMérieux), but six of the seven isolates grew on ChromID extended-spectrum-β-lactamase (ESBL) medium (bioMérieux), as they coproduced an ESBL and/or a plasmid-encoded cephalosporinase. The production of a carbapenemase was detected in 57.1%, 71.4%, 71.4%, and 100% of the E. coli isolates using the Carba NP test, the Rapidec Carba NP test (bioMérieux), a matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) hydrolysis assay (Bruker), and the OXA-48 K-SeT assay (Coris BioConcept), respectively. Our results indicate that OXA-244-producing E. coli isolates are difficult to detect, which may lead to their silent spread. Copyright © 2017 American Society for Microbiology.

    To compare clinical and economic outcomes in patients with community-acquired intra-abdominal infection (IAI) due to extended spectrum beta-lactamase (ESBL) producing (ESBL-positive) bacteria versus non-ESBL-producing (ESBL-negative) bacteria in China. This was a retrospective chart review study of patients hospitalized with community-acquired IAI due to ESBL-positive or ESBL-negative infections caused by Escherichia coli or Klebsiella spp. Data were collected from six hospitals in China that participated in the Study for Monitoring Antibiotic Resistance Trends (SMART) during 2006-2007. Outcomes included clinical response at discharge and following first-line antibiotic, number of antibiotic agents and classes, duration of hospitalization, and overall hospitalization and intravenous antibiotic costs. Of the 85 patients included in the study, 32 (37.6%) had ESBL-positive and 53 (62.4%) had ESBL-negative infections; E. coli was responsible for 77.6% of infections. Infection resolved at discharge in 30 (93.8%) ESBL-positive and 48 (90.6%) ESBL-negative patients (P = NS). Fewer ESBL-positive patients achieved complete response following first-line antibiotics (56.3% versus 83.0%; P = 0.01). ESBL-positive patients required longer antibiotic treatment, more antibiotics, longer hospitalization (24.3 versus 14.6 days; 1.67-fold ratio; P = 0.001), and incurred higher hospitalization costs ( yen24,604 vs. yen13,788; $3604 vs. $2020; 1.78-fold ratio; P < 0.001). Patients with ESBL-positive infection had similar resolution rates at discharge compared to those with ESBL-negative infection, despite poorer first-line antibiotic response. However, ESBL-positive infection led to significantly greater hospitalization cost and intravenous antibiotic cost, and longer hospital stay.

    The National Institute for Health and Care Excellence (NICE) invited the manufacturer of aflibercept (Sanofi) to submit clinical and cost-effectiveness evidence for aflibercept in combination with irinotecan and fluorouracil-based therapy [irinotecan/5-fluorouracil/folinic acid (FOLFIRI)] for the treatment of metastatic colorectal cancer which has progressed following prior oxaliplatin-based chemotherapy, as part of the Institute's Single Technology Appraisal process. The Centre for Reviews and Dissemination and Centre for Health Economics at the University of York were commissioned to act as the independent Evidence Review Group (ERG). This article provides a description of the company submission, the ERG review and the resulting NICE guidance TA307 issued in March 2014. The ERG critically reviewed the evidence presented in the manufacturer's submission and identified areas requiring clarification, for which the manufacturer provided additional evidence. The clinical effectiveness data were derived from one good-quality double-blind randomised controlled trial (RCT), the VELOUR trial, which compared aflibercept plus FOLFIRI with placebo plus FOLFIRI. This RCT found a small but statistically significant increase in overall survival (OS); the difference in median OS was 1.44 months (13.5 months in the aflibercept group and 12.06 months in the placebo group). There was also a statistically significant increase in progression-free survival (PFS) with aflibercept; the difference in median PFS was 2.23 months (6.9 months in the aflibercept group and 4.67 months in the placebo group). However, grade 3-4 adverse events were more frequent in the aflibercept group than the placebo group: 83.5% compared with 62.5%. Treatment-emergent adverse events led to permanent discontinuation of treatment in 26.8% of patients in the aflibercept group and 12.1% of patients in the placebo group. The manufacturer's submission included an estimation of mean OS benefit based on extrapolation

    ABSTRACT The global spread of carbapenemase-producing Enterobacteriaceae (CPE) that are often resistant to most, if not all, classes of antibiotics is a major public health concern. The NDM-1 carbapenemase is among the most worrisome carbapenemases given its rapid worldwide spread. We have developed and evaluated a lateral flow immunoassay (LFIA) (called the NDM LFIA) for the rapid and reliable detection of NDM-like carbapenemase-producing Enterobacteriaceae from culture colonies. We evaluated the NDM LFIA using 175 reference enterobacterial isolates with characterized β-lactamase gene content and 74 nonduplicate consecutive carbapenem-resistant clinical isolates referred for expertise to the French National Reference Center (NRC) for Antibiotic Resistance during a 1-week period (in June 2016). The reference collection included 55 non-carbapenemase producers and 120 carbapenemase producers, including 27 NDM producers. All 27 NDM-like carbapenemase producers of the reference collection were correctly detected in less than 15 min by the NDM LFIA, including 22 strains producing NDM-1, 2 producing NDM-4, 1 producing NDM-5, 1 producing NDM-7, and 1 producing NDM-9. All non-NDM-1 producers gave a negative result with the NDM LFIA. No cross-reaction was observed with carbapenemases (VIM, IMP, NDM, KPC, and OXA-48-like), extended-spectrum β-lactamases (ESBLs) (TEM, SHV, and CTX-M), AmpCs (CMY-2, DHA-2, and ACC-1), and oxacillinases (OXA-1, -2, -9, and -10). Similarly, among the 74 referred nonduplicate consecutive clinical isolates, all 7 NDM-like producers were identified. Overall, the sensitivity and specificity of the assay were 100% for NDM-like carbapenemase detection with strains cultured on agar. The NDM LFIA was efficient, rapid, and easy to implement in the routine workflow of a clinical microbiology laboratory for the confirmation of NDM-like carbapenemase-producing Enterobacteriaceae.

    Healthcare guidelines are an important vehicle in establishing up-to-date evidence based medicine (EBM) in clinical practice. Due to varying development processes, clinical guidelines created by different institutions can often contain contrasting recommendations. This can have implications for optimal and standardized patient care across management settings. The similarities and differences of treatment recommendations made in the National Institute for Health and Care Excellence (NICE), The European Association of Urology (EAU), and the International Consultation on Continence (ICI) guidelines for neurogenic lower urinary tract dysfunction (NLUTD) were assessed. The guidelines generally agree on their approach to conservative management, including behavioral therapies, and catheterization techniques. There was discrepancy on the benefit of using an alpha blocker in NLUTD and bladder outlet obstruction (BOO) and administering Botulinum toxin A (Onabotulinum-A) in NLUTD. The highest degree of divergence was seen in recommendations for surgical treatments, where the EAU made gender-specific recommendations, and gave continent urinary diversion higher preference than given in the NICE and ICI guidelines. In the absence of high-quality clinical evidence, many of the recommendations made across all three guidelines are based on expert opinion. NICE, the EAU and ICI have similarities but they place differing emphasis on costs and expert opinion, which translated in notably different recommendations. It is evident that increased research efforts, possibly in the form of prospective registries, pragmatic trials, and resource utilization studies are necessary to improve the underlying evidence base for NLUTD, and subsequently the strength and concordance of recommendations across guidelines. © 2018 Wiley Periodicals, Inc.

    Snow is crucial over sea ice due to its conflicting role in reflecting the incoming solar energy and reducing the heat transfer so that its temporal and spatial variability are important to estimate. During the Norwegian Young Sea ICE (N-ICE2015) campaign, snow physical properties and variability were examined, and results from April until mid-June 2015 are presented here. Overall, the snow thickness was about 20 cm higher than the climatology for second-year ice, with an average of 55 ± 27 cm and 32 ± 20 cm on first-year ice. The average density was 350-400 kg m-3 in spring, with higher values in June due to melting. Due to flooding in March, larger variability in snow water equivalent was observed. However, the snow structure was quite homogeneous in spring due to warmer weather and lower amount of storms passing over the field camp. The snow was mostly consisted of wind slab, faceted, and depth hoar type crystals with occasional fresh snow. These observations highlight the more dynamic character of evolution of snow properties over sea ice compared to previous observations, due to more variable sea ice and weather conditions in this area. The snowpack was isothermal as early as 10 June with the first onset of melt clearly identified in early June. Based on our observations, we estimate than snow could be accurately represented by a three to four layers modeling approach, in order to better consider the high variability of snow thickness and density together with the rapid metamorphose of the snow in springtime.

    Full Text Available Background: Pseudomonas aeruginosa is one of the leading causes of hospital infections in patients hospitalized for a 10 day period or over. It is also considered to be the most important cause of the burn wound infection. Approximately 75% of deaths in burned patients are due to wound infection and the subsequent septicemia. Clinical use of antibiotics has increasingly led to the global distribution of P. aeruginosa isolates with multi-drug resistance. The study was launched to determine the antimicrobial susceptibility pattern and the presence of the extended-spectrum-beta lactamase (ESBL in P.aeruginosa strains isolated from clinical specimens. Methods: Totally, 175 P. aeruginosa strains were isolated from clinical samples and identified by standard methods. The pattern of antimicrobial resistance was then performed on the isolates using Disk Agar Diffusion (DAD according to CLSI Guideline. Primary screening test for ESBL producing strains was performed by ceftazidim antibiotic disk using disk diffusion method. Combined disk method was used to confirm ESBL producing bacteria. Results: The rate of antimicrobial resistance of P.aeruginosa isolates were 64% to ticarcillin, 52.2% to cefepime, 68.6% to ticarcillin/clavolanic acid, 68.6% to ceftazidime, 67.4% to amikacin, 68.6% to gentamicin, 48% to imipenem, 77.7% to ciprofloxacin and 5.1% to polymixcine B. In the primary screening test, 120 isolates of P.aeruginosa strains were resistant to ceftazidime. In the combined disk method, 66 isolates (55% were positive for ESBLs. Conclusion: Polymixcine B was found to be the most effective antimicrobial agent in this study. Bacteria carrying ESBL genes may increase mortality and morbidity. Thus, their accurate diagnosis is of extreme importance to prevent from the treatment failure resulted from improper antibiotic administration.

  17. Critical Imperative for the Reform of British Interpretation of Fetal Heart Rate Decelerations: Analysis of FIGO and NICE Guidelines, Post-Truth Foundations, Cognitive Fallacies, Myths and Occam’s Razor

    Cardiotocography (CTG) has disappointingly failed to show good predictability for fetal acidemia or neonatal outcomes in several large studies. A complete rethink of CTG interpretation will not be out of place. Fetal heart rate (FHR) decelerations are the most common deviations, benign as well as manifestation of impending fetal hypoxemia/acidemia, much more commonly than FHR baseline or variability. Their specific nomenclature is important (center-stage) because it provides the basic concepts and framework on which the complex “pattern recognition” of CTG interpretation by clinicians depends. Unfortunately, the discrimination of FHR decelerations seems to be muddled since the British obstetrics adopted the concept of vast majority of FHR decelerations being “variable” (cord-compression). With proliferation of confusing waveform criteria, “atypical variables” became the commonest cause of suspicious/pathological CTG. However, National Institute for Health and Care Excellence (NICE) (2014) had to disband the “typical” and “atypical” terminology because of flawed classifying criteria. This analytical review makes a strong case that there are major and fundamental framing and confirmation fallacies (not just biases) in interpretation of FHR decelerations by NICE (2014) and International Federation of Gynecology and Obstetrics (FIGO) (2015), probably the biggest in modern medicine. This “post-truth” approach is incompatible with scientific practice. Moreover, it amounts to setting oneself for failure. The inertia to change could be best described as “backfire effect”. There is abundant evidence that head-compression (and other non-hypoxic mediators) causes rapid rather than shallow/gradual decelerations. Currently, the vast majority of decelerations are attributed to unproven cord compression underpinned by flawed disproven pathophysiological hypotheses. Their further discrimination based on abstract, random, trial and error criteria remains

    Treatment of infectious diseases is becoming more challenging with each passing year. This is especially true for infections caused by Pseudomonas aeruginosa, an opportunistic pathogen with the ability to rapidly develop resistance to multiple classes of antibiotics. This study was conducted to determine the prevalence of metallo-β-lactamase (MBL)-producing strains among multidrug-resistant P. aeruginosa strains isolated from burn patients. The isolates were identified, tested for susceptibility to various antimicrobial agents, and screened for the presence of MβLs by using the double-disk synergy test. The minimal inhibitory concentration of imipenem was determined by microplate broth dilution method on Mueller-Hinton agar. To detect VIM, SIM, and GIM MBLs, the isolates were subjected to polymerase chain reaction. In this study, we identified 100 P. aeruginosa isolates from 176 clinical specimens obtained from burn patients. The isolates showed maximum resistance to ampicillin (100%), ceftazidime (94%), and ceftriaxone (89%). The CLSI-MBL phenotypic test showed that of the 100 P. aeruginosa isolates, 22 (22%) were positive for MBL production in the double-disk synergy test. Of the 22 MBL-positive P. aeruginosa isolates, 8 were resistant to imipenem. PCR analysis showed that 8 isolates were positive for blaVIM1. The other genes blaSIM1 and blaGIM1 were not detected. The study results demonstrate the serious therapeutic threat of the spread of MBL producers among P. aeruginosa populations. Metallo-β-lactamases were detected in 22% of imipenem-resistant P. aeruginosa isolates. Early detection and infection-control practices are the best antimicrobial strategies for this organism; therefore, systematic surveillance to detect MBL producers is necessary.

    Full Text Available Ectopic secretion of ACTH from non-pituitary tumors, referred to as ectopic ACTH syndrome (EAS, accounts for about 10–20% of Cushing’s syndrome (CS. Ectopic hormone-secreting pheochromocytomas (Pheo are rare. The first publication of association between pheochromocytoma and Cushing’s syndrome by Roux is dated 1955. Pheochromocytoma represents a rare cause of hypercortisolism, accounting for less than 5 % of ectopic Cushing’s syndrome while less than 1 % of pheochromocytomas is accompanied by Cushing’s syndrome. We are reporting 4 cases of ACTH-secreting pheochromocytoma presenting as Cushing’s syndrome. Data from 4 patients were analysed. There were 4 women from 50 to 63 years old. All patients had a clinical presentation of hypercorticoidism. Their levels of adrenocorticotropic hormone in plasma, 24-hour urinary free cortisol and urinary catecholamine were high. Computed tomography scan of the abdomen in all cases revealed a mass in the left adrenal gland. Left sided adrenalectomy was performed under treatment with a-blocker doxazosin and b-blocker atenolol. Histological examination revealed in 3 cases – pheocromocytoma and in 1 case corticomedullary mixed tumor of the adrenal gland. Additional immunostaining (IHCof these tumors showed positive immunostaining for chromogranin and ACTH. The IHC search for somatostatin receptors of subtype 2 and 5 (SSTR2, SSTR5 was performed in 3 cases and showed predominately expression SSTR2. The case index of Ki-67 ranged, from 0,5 to 4%. Biochemical signs of hypercortisolism rapidly began to disappear after surgery. Follow up of the patients during the next 2 years on average was with disease remission.

    new five-stratum risk stratification system was produced, and its prognostic power was compared against the current system, with PCSM as the outcome. The results were analysed using a Cox hazards model, the log-rank test, Kaplan-Meier curves, competing-risks regression, and concordance indices. In the training set, the new risk stratification system identified distinct subgroups with different risks of PCSM in pair-wise comparison (p < 0.0001. Specifically, the new classification identified a very low-risk group (Group 1, a subgroup of intermediate-risk cancers with a low PCSM risk (Group 2, hazard ratio [HR] 1.62 [95% CI 0.96-2.75], and a subgroup of intermediate-risk cancers with an increased PCSM risk (Group 3, HR 3.35 [95% CI 2.04-5.49] (p < 0.0001. High-risk cancers were also sub-classified by the new system into subgroups with lower and higher PCSM risk: Group 4 (HR 5.03 [95% CI 3.25-7.80] and Group 5 (HR 17.28 [95% CI 11.2-26.67] (p < 0.0001, respectively. These results were recapitulated in the testing set and remained robust after inclusion of competing risks. In comparison to the current risk stratification system, the new system demonstrated improved prognostic performance, with a concordance index of 0.75 (95% CI 0.72-0.77 versus 0.69 (95% CI 0.66-0.71 (p < 0.0001. In an external cohort, the new system achieved a concordance index of 0.79 (95% CI 0.75-0.84 for predicting PCSM versus 0.66 (95% CI 0.63-0.69 (p < 0.0001 for the current NICE risk stratification system. The main limitations of the study were that it was registry based and that follow-up was relatively short.A novel and simple five-stratum risk stratification system outperforms the standard three-stratum risk stratification system in predicting the risk of PCSM at diagnosis in men with primary non-metastatic prostate cancer, even when accounting for competing risks. This model also allows delineation of new clinically relevant subgroups of men who might potentially receive more appropriate

    Extended spectrum betalactamase (ESBL)-producing organisms are a major cause of hospital-acquired infections. ESBL-producing Escherichia coli (E. coli) have been recovered from the hospital environment. These drug-resistant organisms have also been found to be present in humans as commensals. The present investigation intended to isolate ESBL-producing E. coli from the gut of already infected patients; to date, only a few studies have shown evidence of the gut microflora as a major source of infection. This study aimed to detect the presence of ESBL genes in E.coli that are isolated from the gut of patients who have already been infected with the same organism. A total of 70 non-repetitive faecal samples were collected from in-patients of our hospital. These in-patients were clinically diagnosed and were culture-positive for ESBL-producing E. coli either from blood, urine, or pus. Standard microbiological methods were used to detect ESBL from clinical and gut isolates. Genes coding for major betalactamase enzymes such as bla CTX-M , bla TEM, and bla SHV were investigated by polymerase chain reaction (PCR). ESBL-producing E. coli was isolated from 15 (21 per cent) faecal samples of the 70 samples that were cultured. PCR revealed that out of these 15 isolates, the bla CTX-M gene was found in 13 (86.6 per cent) isolates, the bla TEM was present in 11 (73.3 per cent) isolates, and bla SHV only in eight (53.3 per cent) isolates. All 15 clinical and gut isolates had similar phenotypic characters and eight of the 15 patients had similar pattern of genes (bla TEM, bla CTX-M, and bla SHV) in their clinical and gut isolates. Strains with multiple betalactamase genes that colonise the gut of hospitalised patients are a potential threat and it may be a potential source of infection.

    Learning Together is a complex educational intervention aimed at improving health outcomes for children and young people. There is an additional cost as two doctors are seeing patients together for a longer appointment than a standard general practice (GP) appointment. Our approach combines the impact of the training clinics on activity in South London in 2014-15 with health gain, using NICE guidance and standards to allow comparison of training options. Activity data was collected from Training Practices hosting Learning Together. A computer based model was developed to analyse the costs of the Learning Together intervention compared to usual training in a partial economic evaluation. The results of the model were used to value the health gain required to make the intervention cost effective. Data were returned for 363 patients booked into 61 clinics across 16 Training Practices. Learning Together clinics resulted in an increase in costs of £37 per clinic. Threshold analysis illustrated one child with a common illness like constipation needs to be well for two weeks, in one Practice hosting four training clinics for the clinics to be considered cost effective. Learning Together is of minimal training cost. Our threshold analysis produced a rubric that can be used locally to test cost effectiveness at a Practice or Programme level.

    The British National Institute of Clinical Excellence (NICE) guidelines recommend to use drug-eluting stents (DES) instead of bare-metal stents (BMS) only in lesions >15 mm in length or in vessels stent length and stent diameter on in-stent restenosis (ISR) in the BASKET-PROVE study population and evaluated the cost-effectiveness of DES compared to BMS. The BASKET-PROVE trial compared DES vs BMS in large coronary arteries (≥3 mm). We calculated incremental cost-effectiveness ratios (ICERs) and cost-effectiveness acceptability curves with regard to quality-adjusted life years (QALYs) gained and target lesion revascularizations (TLRs) avoided. A total of 2278 patients were included in the analysis. A total of 74 ISR in 63 patients were observed. In-stent restenosis was significantly more frequent in segments treated with a BMS compared to segments treated with a DES (5.4% vs 0.76%; Pstent length >15 mm and ≤15 mm, respectively. With the use of DES in short lesions, there was only a minimal gain of 0.005 in QALYs. At a threshold of 10 000 CHF per TLR avoided, DES had a high probability of being cost-effective. In the BASKET-PROVE study population, the strongest predictor of ISR is the use of a BMS, even in patients in need of stents ≥3.0 mm and ≤15 mm lesion length and DES were cost-effective. This should prompt the NICE to reevaluate its recommendation to use DES instead of BMS only in vessels 15 mm length. © 2016 John Wiley & Sons Ltd.

    We conclude that multilocular cysts are 3 cm and over, or elevated types as in mucin producing pancreatic tumors must be neoplasm in the pathological study. But, we question whether or not we can diagnose the elevated type before the operation. So, for the purpose of making a clear guideline of diagnosis for elevated types, we examined 46 operating cases of mucin producing tumors (Kuroda type I) documented from 1985 to 1994. We examined existence, height and properties of elevated lesions, 25 cases of elevated type and 21 cases of flat type. There is a significant difference of height with US and CT, and existence of enhancement with CT. As a result, we have obtained the following guidelines. The height of an elevated lesion with US is 4 mm and over, and the height of that with CT is 3 mm and over. It is enhanced with CT. Therefore, we find it possible to diagnose elevated types with US and CT. (author)

    The evidence base which supported the National Institute for Health and Clinical Excellence (NICE) published Clinical Guideline 3 was limited and 50% was graded as amber. However, the use of tests as part of pre-operative work-up remains a low-cost but high-volume activity within the NHS, with substantial resource implications. The objective of this study was to identify, evaluate and synthesise the published evidence on the clinical effectiveness and cost-effectiveness of the routine use of three tests, full blood counts (FBCs), urea and electrolytes tests (U&Es) and pulmonary function tests, in the pre-operative work-up of otherwise healthy patients undergoing minor or intermediate surgery in the NHS. The aims of this study were to estimate the clinical effectiveness and cost-effectiveness of routine pre-operative testing of FBC, electrolytes and renal function and pulmonary function in adult patients classified as American Society of Anaesthesiologists (ASA) grades 1 and 2 undergoing elective minor (grade 1) or intermediate (grade 2) surgical procedures; to compare NICE recommendations with current practice; to evaluate the cost-effectiveness of mandating or withdrawing each of these tests in this patient group; and to identify the expected value of information and whether or not it has value to the NHS in commissioning further primary research into the use of these tests in this group of patients. The following electronic bibliographic databases were searched: (1) BIOSIS; (2) Cumulative Index to Nursing and Allied Health Literature; (3) Cochrane Database of Systematic Reviews; (4) Cochrane Central Register of Controlled Trials; (5) EMBASE; (6) MEDLINE; (7) MEDLINE In-Process & Other Non-Indexed Citations; (8) NHS Database of Abstracts of Reviews of Effects; (9) NBS Health Technology Assessment Database; and (10) Science Citation Index.

    Friedman, the United Kingdom's National Institute for Health and Care Excellence (NICE), and the American College of Obstetricians and Gynecologists/Society for Maternal-Fetal Medicine (ACOG/SMFM) support different active labor diagnostic guidelines. Our aims were to compare likelihoods for cesarean delivery among women admitted before vs in active labor by diagnostic guideline (within-guideline comparisons) and between women admitted in active labor per one or more of the guidelines (between-guideline comparisons). Active labor diagnostic guidelines were retrospectively applied to cervical examination data from nulliparous women with spontaneous labor onset (n = 2573). Generalized linear models were used to determine outcome likelihoods within- and between-guideline groups. At admission, 15.7%, 48.3%, and 10.1% of nulliparous women were in active labor per Friedman, NICE, and ACOG/SMFM diagnostic guidelines, respectively. Cesarean delivery was more likely among women admitted before vs in active labor per the Friedman (AOR 1.75 [95% CI 1.08-2.82] or NICE guideline (AOR 2.55 [95% CI 1.84-3.53]). Between guidelines, cesarean delivery was less likely among women admitted in active labor per the NICE guideline, as compared with the ACOG/SMFM guideline (AOR 0.55 [95% CI 0.35-0.88]). Many nulliparous women are admitted to the hospital before active labor onset. These women are significantly more likely to have a cesarean delivery. Diagnosing active labor before admission or before intervention to speed labor may be one component of a multi-faceted approach to decreasing the primary cesarean rate in the United States. The NICE diagnostic guideline is more inclusive than Friedman or ACOG/SMFM guidelines and its use may be the most clinically useful for safely lowering cesarean rates. © 2017 Wiley Periodicals, Inc.

    Carboxytherapy is the therapeutic use of carbon dioxide (CO2) in its gaseous state. Since 1933, carboxytherapy has referred to either the subcutaneous injection of CO2 or percutaneous application in a warm bath. The present clinical study was performed to determine if there were any changes in the dermis after the application of a transcutaneous gel, which is claimed to produce CO2, and, if so, how these changes compared to those with CO2 injection. Ten patients received transcutaneous treatment with the gel on one side of the face and the other side without any product was used as a control. We used videocapillaroscopy with an optic probe (VCSO) to evaluate the changes in the microcirculation of the skin. VCSO was performed for the treated right and untreated left ear lobes in each patient. VCSO was performed before treatment was started (VCSO1) and after 7 days of treatment (VCSO2). A comparison of VCSO1 to VCSO2 showed an increase in the microcirculation, an increase in vertical and horizontal capillaries, and a reduction in the area of ischemia. These results are similar to those observed in other studies with CO2 injection. In conclusion, use of this transcutaneous CO2 gel produced changes in the dermis similar to those observed with subcutaneous injection of CO2.

    The alpha particle emitter Radium-223 dichloride ("2"2"3RaCl_2) has recently been approved for treatment of late-stage bone metastatic prostate cancer. There is considerable interest in studying this new agent outside of the clinical setting, however the supply of "2"2"3Ra is limited and expensive. We have engineered a "2"2"3Ra microgenerator using traces of "2"2"7Ac previously generated from cyclotron-produced "2"2"5Ac. Radiochemically pure "2"2"3RaCl_2 was made, characterized, evaluated in vivo, and the source was recovered in high yield for regeneration of the microgenerator. - Highlights: • A "2"2"3Ra microgenerator was built using residual "2"2"7Ac from cyclotron-produced "2"2"5Ac. • Following "2"2"5Ac decay, the residual "2"2"7Ac was processed into pure "2"2"3Ra. • "2"2"7Ac and "2"2"7Th were recovered in high yield for a permanent supply of "2"2"3Ra. • Clinically supplied and generator-produced "2"2"3Ra have equivalent in vivo distribution. • Microdose column provides sufficient material for research use.

  16. Staphylococcus aureus produces membrane-derived vesicles that induce host cell death.

    Directory of Open Access Journals (Sweden)

    Mamata Gurung

    Full Text Available Gram-negative bacteria produce outer membrane vesicles that play a role in the delivery of virulence factors to host cells. However, little is known about the membrane-derived vesicles (MVs produced by gram-positive bacteria. The present study examined the production of MVs from Staphylococcus aureus and investigated the delivery of MVs to host cells and subsequent cytotoxicity. Four S. aureus strains tested, two type strains and two clinical isolates, produced spherical nanovesicles during in vitro culture. MVs were also produced during in vivo infection of a clinical S. aureus isolate in a mouse pneumonia model. Proteomic analysis showed that 143 different proteins were identified in the S. aureus-derived MVs. S. aureus MVs were interacted with the plasma membrane of host cells via a cholesterol-rich membrane microdomain and then delivered their component protein A to host cells within 30 min. Intact S. aureus MVs induced apoptosis of HEp-2 cells in a dose-dependent manner, whereas lysed MVs neither delivered their component into the cytosol of host cells nor induced cytotoxicity. In conclusion, this study is the first report that S. aureus MVs are an important vehicle for delivery of bacterial effector molecules to host cells.

    Homeopathy uses information gathered from healthy volunteers taking homeopathic substances (pathogenetic trials) for clinical treatment. It is controversial whether such studies produce symptoms different from those produced by placebo. To test whether homeopathic preparations produce different symptoms than placebo in healthy volunteers. Three armed, double-blind, placebo controlled randomised experimental pathogenetic study in 25 healthy volunteers who took either one of two homeopathic remedies, Natrum muriaticum and Arsenicum album in 30CH or identical placebo. Main outcome parameter was the number of remedy-specific symptoms per group. On average, 6 symptoms typical for Arsenicum album were experienced by participants taking arsenicum album, 5 symptoms typical for Natrum muriaticum by those taking natrum muriaticum, and 11 non-specific symptoms by those in the placebo group. Differences were significant overall (Kruskall Wallis test, p = 0.0002,) and significantly different from placebo (Mann-Whitney test, p = 0.001). Homeopathic remedies produce different symptoms than placebo. Copyright (c) 2009 S. Karger AG, Basel.

    Purpose of Presentation This research presents the overall logic model for the evaluation plan for a three-year NASA-funded project focused on teacher professional development. This session will highlight how we are using data to continually revise the evaluation plan, and we will also share insights about communication between the external evaluator and the PI. Objectives and Research Questions PEL leverages three NASA NICE projects with a high school district, providing professional development for teachers, learning opportunities for students, parental involvement and interaction with NASA scientists. PEL aims to increase Climate Science literacy in high school students, with a focus on Hispanic students, through scientific argumentation using authentic NASA data. Our research will concentrate on investigating the following questions: 1. What do we know about the alternative conceptions students' hold about climate science and what is challenging for students? 2. Are students developing climate science literacy, especially in the difficult concept areas, after PEL implementation? 3. How effective is PEL in nurturing scientific argumentation skills? 4. How effective are the resources we are providing in PEL? 5. Is there evidence that teachers are establishing stronger leadership capacity in their schools? Theoretical Framework for PEL Evaluation The expectancy-value theory of achievement motivation (E-V-C) (Fan, 2011; Wigfield & Eccles, 1994) provides a theoretical foundation for the research. Expectancy is the degree to which a teacher or student has reason to expect that they will be successful in school. Value indicates whether they think that performance at school will be worthwhile to them. Cost is the perceived sacrifices that must be undertaken, or factors that can inhibit a successful performance at school. For students, data from an embedded E-V-C investigation will help articulate how E-V-C factors relate to student interest in science, continuing to

  2. RBE and clinical response in radiotherapy with neutron beams

    Consideration of the clinical results reported, when a cyclotron produced neutron beam was used for treatments in the pelvis region, suggested that a constant RBE of 3 should not have been used for all neutron doses. Instead a variable RBE, which increased from approximately 3 to 8 (with decreasing dose), should have been used. Although some of these RBE values are much higher than 3, they have been observed in clinical practice. An ''equivalent photon'' isodose plan was produced by employing a variable RBE and, by taking a TDF limit of 86 for bowel, an isoeffect plan was produced. This shows that in the clinical situation under consideration much of the pelvis was overdosed. Doses to tumour cells and late effects are also briefly considered. It is suggested that, in neutron therapy, both an ''equivalent photon'' isodose plan and an isoeffect plan should be produced prior to treatment. (author)

    Mesenchymal stem cells isolated from different dental tissues have been described to have osteogenic/odontogenic-like differentiation capacity, but little attention has been paid to the biochemical composition of the material that each produces. Here, we used Raman spectroscopy to analyze the mineralized materials produced in vitro by different dental cell populations, and we compared them with the biochemical composition of native dental tissues. We show that different dental stem cell populations produce materials that differ in their mineral and matrix composition and that these differ from those of native dental tissues. In vitro, BCMP (bone chip mass population), SCAP (stem cells from apical papilla), and SHED (stem cells from human-exfoliated deciduous teeth) cells produce a more highly mineralized matrix when compared with that produced by PDL (periodontal ligament), DPA (dental pulp adult), and GF (gingival fibroblast) cells. Principal component analyses of Raman spectra further demonstrated that the crystallinity and carbonate substitution environments in the material produced by each cell type varied, with DPA cells, for example, producing a more carbonate-substituted mineral and with SCAP, SHED, and GF cells creating a less crystalline material when compared with other dental stem cells and native tissues. These variations in mineral composition reveal intrinsic differences in the various cell populations, which may in turn affect their specific clinical applications. © International & American Associations for Dental Research 2015.

    The emergence of extended-spectrum beta-lactamase (ESBL)-producing isolates has important clinical and therapeutic implications. High prevalence of ESBL-producing Enterobacteriaceae has been reported in the literature for clinical samples from a variety of infection sites. The present study was undertaken to evaluate the prevalence of ESBL-producing Enterobacteriaceae, and to perform molecular characterization and antimicrobial susceptibility testing of clinical isolates from patients admitted to the intensive care units at Hamad Medical Corporation, Doha, Qatar, from November 2012 to October 2013. A total of 629 Enterobacteriaceae isolates were included in the study. Identification and susceptibility testing was performed using Phoenix (Becton Dickinson) and the ESBL producers were confirmed by double-disk potentiation as recommended by the Clinical and Laboratory Standards Institute. Molecular analysis of the ESBL producers was performed by polymerase chain reaction. In total, 109 isolates (17.3 %) were confirmed as ESBL producers and all were sensitive to meropenem in routine susceptibility assays. Most of the ESBL producers (99.1 %) were resistant to amoxicillin/clavulanic acid and ceftriaxone and 93.6 % were resistant to cefepime. Among the ESBL-producing genes, bla CTX-M (66.1 %) was the most prevalent, followed by bla SHV (53.2 %) and bla TEM (40.4 %). These findings show the high prevalence of ESBL-producing Enterobacteriaceae within the intensive care units at Hamad Medical Corporation, Qatar, and emphasize the need for judicious use of antibiotics and the implementation of strict infection control measures.

  5. "What constitutes a 'problem'?" Producing 'alcohol problems' through online counselling encounters.

    Typically, health policy, practice and research views alcohol and other drug (AOD) 'problems' as objective things waiting to be detected, diagnosed and treated. However, this approach to policy development and treatment downplays the role of clinical practices, tools, discourses, and systems in shaping how AOD use is constituted as a 'problem'. For instance, people might present to AOD treatment with multiple psycho-social concerns, but usually only a singular AOD-associated 'problem' is considered serviceable. As the assumed nature of 'the serviceable problem' influences what treatment responses people receive, and how they may come to be enacted as 'addicted' or 'normal' subjects, it is important to subject clinical practices of problem formulation to critical analysis. Given that the reach of AOD treatment has expanded via the online medium, in this article we examine how 'problems' are produced in online alcohol counselling encounters involving people aged 55 and over. Drawing on poststructural approaches to problematisation, we not only trace how and what 'problems' are produced, but also what effects these give rise to. We discuss three approaches to problem formulation: (1) Addiction discourses at work; (2) Moving between concerns and alcohol 'problems'; (3) Making 'problems' complex and multiple. On the basis of this analysis, we argue that online AOD counselling does not just respond to pre-existing 'AOD problems'. Rather, through the social and clinical practices of formulation at work in clinical encounters, online counselling also produces them. Thus, given a different set of circumstances, practices and relations, 'problems' might be defined or emerge differently-perhaps not as 'problems' at all or perhaps as different kinds of concerns. We conclude by highlighting the need for a critical reflexivity in AOD treatment and policy in order to open up possibilities for different ways of engaging with, and responding to, people's needs in their complexity

    Introduction Gastro-oesophageal reflux disease (GORD) is a common, chronic debilitating condition. Surgical management traditionally involves fundoplication. Magnetic sphincter augmentation (MSA) is a new definitive treatment. We describe our experience of introducing this innovative therapy into NHS practice and report the early clinical outcomes. Methods MSA was introduced into NHS practice following successful acceptance of a cost-effective business plan and close observation of National Institute for Health and Care Excellence (NICE) recommendations for new procedures, including a carefully planned prospective data collection over a two-year follow-up period. Results Forty-seven patients underwent MSA over the 40-month period. Reflux health-related quality of life (GERD-HRQL) was significantly improved after the procedure and maintained at one- and two-year (P business plan and compliance with NICE recommendations.

    As part of the National Institute for Health and Care Excellence's (NICE) Single Technology Appraisal (STA) process, ruxolitinib was assessed to determine the clinical and cost effectiveness of its use in the treatment of disease-related splenomegaly or symptoms in adults with myelofibrosis. Ruxolitinib had previously been assessed as part of the STA process and was not recommended in NICE guidance issued in June 2013 (TA289). A review of TA289 was commissioned following the availability of new longer-term survival data; a price discount patient access scheme (PAS) was also introduced. The Centre for Reviews and Dissemination (CRD) and Centre for Health Economics (CHE) Technology Appraisal Group at the University of York was commissioned to act as the independent Evidence Review Group (ERG). This article provides a summary of the manufacturer or sponsor of the technology's (referred to as the company) submission, the ERG review and the resulting NICE guidance issued in March 2016. The main clinical effectiveness data were derived from two good-quality multicentre randomised controlled trials (RCTs): COMFORT-II compared ruxolitinib with best available therapy (BAT) and COMFORT-I compared ruxolitinib with placebo. Both RCTs demonstrated a statistically significant reduction in splenomegaly and its associated symptoms in intermediate-2 and high-risk myelofibrosis patients. Overall survival was statistically significantly improved with ruxolitinib compared with BAT at 3.5 years of follow-up in the COMFORT-II trial (hazard ratio 0.58, 95 % CI 0.36-0.93). Grade 3-4 adverse events were more frequent in the ruxolitinib group than in the BAT group; 42 % compared with 25 %. Evidence relating to patients with lower-risk disease or low platelet counts (50-100 × 10 9 /L) was less robust. The company's economic model was well-presented and had an appropriate model structure. The base-case incremental cost-effectiveness ratio (ICER) was estimated to be around £45,000 per

    Full Text Available Aim: This study was done to determine the minimum inhibitory concentration (MIC of imipenem for multidrug-resistant (MDR clinical isolates and identify carbapenemase-producing organisms among these MDR isolates. Materials and Methods: The antibiotic susceptibility of clinical isolates was determined by Kirby–Bauer disc diffusion method. MDR isolates showing resistance or reduced susceptibility to carbapenems were further tested for MIC with imipenem and carbapenemase production by Modified Hodge test (MHT. Results: A total of 65 MDR isolates were tested, of which 46 (70.77%, 15 (23%, and 4 (6.15% had MIC in resistant, sensitive, and intermediate range, respectively. MHT was positive for 37 (57% isolates. The most common carbapenemase producers in order of frequency were Acinetobacter baumannii, Klebsiella pneumoniae, Enterobacter aerogenes, Escherichia coli, Pseudomonas spp. Conclusion: Phenotypic tests such as MHT are simple, cost-effective, and easy to perform and hence can be used in any microbiology laboratory to detect carbapenemase production and applied clinically to guide the antimicrobial therapy, especially in severe and life-threatening infections.

  11. The crossroads of countertransference and attribution theory: reinventing clinical training within an evidence-based treatment world.

    Science.gov (United States)

    Lewis, Jeffrey I

    2009-06-01

    Social Psychological research on Person Perception/Attribution Theory has concluded that an individual responds to interpersonal situations based upon their interpretation of the "nature" of that situation. For example, physically attractive people are often attributed niceness and capableness even without any basis in reality. The observer, guided by percepts cum attributions, may treat the attractive participant "as though" these qualities are about them rather than about the observer's internal bias. In psychoanalysis, this social phenomenon takes on individual meaning as countertransference. Therapists seem to experience irrational feelings during the psychotherapy exchange, which remain, whether or not the therapist is conscious of these responses or whether their technical objective includes or ignores their own transference. The attributional tendency to act upon these feelings "as though" they were wholly about the patient may lead to therapeutic disasters. Therefore, clinical training of psychotherapists needs the early inclusion of this concept to prevent subsequent dogmatic and untherapeutic attitudes. This paper will discuss the possibility of disarming the damage rendered by medicalized parsimonious "healing" and the latest fashion, Evidence-Based Treatment, via a translation of assumedly unmeasurable psychoanalytic tenets into multiply measured, investigated areas of social research.

    Full Text Available AbstractBackground: Multidrug resistance and production of extendedspectrum β-lactamases (ESBLs by enteric gramnegativerods in hospitals and community continue to beworsened. We aimed to characterize the multidrug resistanceand determine the prevalence of ESBL production by clinicalisolates of Enterobacteriaceae in southeast Iran.Methods: Gram-negative bacteria isolated from clinical samplesof hospital inpatients and outpatients from three hospitalsin southeast Iran were tested for susceptibility to 10commonly used antimicrobials. For 500 isolates whichshowed resistance to ≥3 antibiotics from different classes,minimum inhibitory concentration, and prevalence of ESBLproduction were determined by agar dilution and double discsynergy method respectively. The isolated bacterial specieswere compared in respect of antibacterial resistance, ESBLproduction, patients' gender, hospital ward, and type ofspecimen.Results: The most frequent resistance was to trimethoprim/sulfamethoxazole, amoxicillin, and tetracycline. Imipenemwith 99.8% and ceftizoxime with 83% susceptibility were themost active agents. A total of 53.8% of isolates expressedESBL production. Escherichia coli and Klebsiella pneumoniaewere most common in outpatients, and inpatients samplesrespectively. Higher rate of resistance to most antibacterialagents and ESBL production was found in samples ofinpatients.Conclusion: The present study showed high prevalence ofESBL-producing Enterobacteriaceae especially in the patientsadmitted to hospital. Infection control strategy with continuousresistance surveillance is essential to monitor in vitro susceptibilityto antibacterial agents currently used in clinicalpractice. Determination of the type of involved ESBL enzymesis important for a better antimicrobial control and empiricaltherapy of critically ill patients in hospitals.Iran J Med Sci 2010; 35(2: 101-108.

  14. Evaluation Apprehension and Impression Management in Clinical Medical Education.

    Science.gov (United States)

    McGaghie, William C

    2018-05-01

    Historically, clinical medical education has relied on subjective evaluations of students and residents to judge their clinical competence. The uncertainty associated with these subjective clinical evaluations has produced evaluation apprehension among learners and attempts to manage one's professional persona (impression management) among peers and supervisors. Such behavior has been documented from antiquity through the Middle Ages to the present, including in two new qualitative studies in this issue of Academic Medicine on the social psychology of clinical medical education. New approaches to medical education, including competency-based education, mastery learning, and assessment methods that unite evaluation and education, are slowly changing the culture of clinical medical education. The author of this Invited Commentary argues that this shift will bring greater transparency and accountability to clinical medical education and gradually reduce evaluation apprehension and the impression management motives it produces.

  15. Metallo-β-Lactamase (MBL)-Producing Enterobacteriaceae in United States Children.

    Logan, Latania K; Bonomo, Robert A

    2016-04-01

    Metallo-β-lactamases (MBLs) are emerging as the most notable resistance determinants in Enterobacteriaceae. In many cases, the genes encoding MBLs are part of complex, mobile genetic elements that carry other resistance determinants. In the United States, there are increasing reports of MBL-producing Enterobacteriaceae, with New Delhi MBLs (NDMs) accounting for the majority of transmissible MBL infections. Many infections caused by NDM-producing bacteria are associated with international travel and medical tourism. However, little recognition of the introduction of MBL-producing Enterobacteriaceae into the pediatric community has followed. Reports suggest that this occurred as early as 2002. Here, we reflect on the unwelcome emergence of MBL-producing Enterobacteriaceae in US children and the available clinical and molecular data associated with spread. Since 2002, there have been disturbing reports that include the most readily transmissible MBLs, bla IMP, bla VIM, and bla NDM types. In the majority of children with available data, a history of foreign travel is absent.

    Extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae present an ever-growing burden in the hospital and community settings, across all ages and demographics. Infections due to ESBL-containing pathogens continue to be associated with significant morbidity and mortality worldwide. With widespread empiric broad-spectrum β-lactam use creating selective pressure, and the resultant emergence of stable, rapidly proliferating ESBL-producing clones with continued horizontal gene transfer across genera, addressing this issue remains imperative. Although well characterized in adults, the epidemiology, risk factors, outcomes, therapies, and control measures for ESBL-producing bacteria are less appreciated in children. This analysis provides a brief summary of ESBL-producing Enterobacteriaceae in children, with a focus on recent clinical and molecular data regarding colonization and infection in nonoutbreak settings.

    Results: Of 638 gram negative bacilli isolates and 3.39% showed imipenem resistance, 2.9% showed MBL production, of which 1.7% were non-fermenters and 1.25% were Enterobacteriaceae, 0.3% showing non-MBL KPC carbapenemas. Most isolates were from the intensive care unit and from post-operative patients. Our findings show that there are significant numbers of isolates having MBL production along with multidrug resistance. There is a need for active surveillance to detect MBL producers.

    Full Text Available Abstract Managing clinical trials, of whatever size and complexity, requires efficient trial management. Trials fail because tried and tested systems handed down through apprenticeships have not been documented, evaluated or published to guide new trialists starting out in this important field. For the past three decades, trialists have invented and reinvented the trial management wheel. We suggest that to improve the successful, timely delivery of important clinical trials for patient benefit, it is time to produce standard trial management guidelines and develop robust methods of evaluation.

  19. Extended-spectrum beta-lactamase-producing bacteria are not detected in supragingival plaque samples from human fecal carriers of ESBL-producing Enterobacteriaceae

    Arne Søraas

    2014-08-01

    Full Text Available Background: The prevalence of infections caused by Cefotaximase-Munich (CTX-M-type extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL-E has rapidly increased during the past 15 years. Enterobacteriaceae are commonly found in the gastrointestinal tract and long-term intestinal carriage is considered important for the spread of ESBL and as a source of clinical infections. Oral biofilm such as supragingival plaque is known to contain numerous antibiotic resistance determinants and may also represent a poorly investigated site for ESBL carriage and further spread. Objective: To investigate possible carriage of ESBL-producing bacteria in supragingival plaque of known fecal carriers of these bacteria. Design: We screened for the presence of aerobic and anaerobic ESBL-producing bacteria and blaCTX-M in supragingival plaque samples from healthy human adults with culture-verified fecal carriage of CTX-M-producing Escherichia coli. The presence or absence of Enterobacteriaceae and ESBL-producing bacteria in plaque samples was evaluated using culture-based methods and consensus CTX-M PCR. Results: Oral samples were obtained from 17 participants with known previous carriage of ESBL-producing E. coli. No ESBL-producing bacteria or ESBL genes were detected using culture-based and molecular methods. One colony of Rahnella aquatilis harboring the class A ESBL gene bla RAHN-1/2 was identified in an oral sample from one of the participants. Conclusion: This pilot study supports the notion that the presence of CTX-M-producing bacteria is uncommon in oral plaque of healthy human adult fecal carriers. Due to the limited number of persons tested, a low prevalence of oral ESBL-carriage in healthy adults or carriage in selected groups of patients cannot be excluded. To our knowledge, this is the first description of an R. aquatilis with the RAHN-1/2 gene in the oral cavity.

    The aim of this study was to characterise the response to ionising radiation of normal tissues from patients that display early and acute hypersensitivity to radiotherapy. Methods include cell proliferation assay using MTT, induced chromosomal aberration testing, cell cycle response to radiation via FACs, mutation analysis of Ataxia Telangiectasia (AT) gene, p53 and AT Western analysis. It is now well appreciated that standard clinical doses (1.8-2 Gy per fraction per day) produce predictable acute and late toxicity in most patients. Occasionally, however, the standard clinical dose produces acute and late toxicity which can exceed the norm both in their extent and timing. The study confirmed the innate cellular radiosensitivity of the clinically radio-hypersensitive patients. No indication of AT gene mutations was found

    To assess incidence rate, risk factors and susceptibility patterns associated with extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli or Klebsiella pneumoniae in community-acquired urinary tract infections (CA-UTIs). A prospective, case-control study was conducted at a tertiary teaching hospital from Jan 2015 to Dec 2016. The results of microbiology cultures were initially screened to include only patients with positive E. coli or K. pneumoniae urine cultures. Afterwards, clinical symptoms were assessed to confirm the UTI. To investigate the risk factors, patients with a positive urine culture for ESBL-producing isolates were assigned as cases, while patients with non-ESBL were assigned as controls. Out of 591 patients included in this study, 57.5% (n = 340) were included in the control group and 42.5% (n = 251) were in the case group. The incidence rate of ESBL-producing isolates was 3.465 cases per 1000-patient hospital admissions. Male gender (OR = 1.856, 95% CI = 1.192-2.889, p = 0.006), pediatrics (OR = 1.676, 95% CI = 1.117-2.517, p = 0.013), patients with comorbidity (OR = 1.542, 95% CI = 1.029-2.312, p = 0.036) and UTI in the previous 12 months (OR = 1.705, 95% CI = 1.106-2.628, p = 0.016) were independently associated with a higher risk of infection. The resistance rate for most commonly prescribed antibiotics was high. Our results suggest that the incidence of ESBL producers among CA-UTIs is high. Male gender, pediatrics, comorbidity and UTI in the previous 12 months were associated with a higher risk for infection. Continuous surveillance and prudent antibiotic use by healthcare professionals are important factors for effective control of ESBL associated infections.

  3. The Devran Petroleum story: Nice idea, now what?

    International Nuclear Information System (INIS)

    Cowan, J.F.

    1993-01-01

    The history of the Devran petroleum company is reviewed. The company began in Ontario in 1982 and its first venture, a 50% partnership with Shell Canada, was to excavate two drilling rooms 430 ft into the depleted Sarnia-London (Ontario) oil field and drill 11 horizontal wells to obtain oil production. This venture produced very little crude and was abandoned due to excessive water inflow. Devran's next initiative was to purchase the Ontario government's share in Onexco Oil and Gas, which had a number of Ontario properties and eight wells. The high netbacks per bbl characteristic of Ontario reservoirs enabled Devran to survive and pay off loans for the Onexco purchase, and the number of Devran's Ontario wells rose to over 50. Devran then acquired a Toronto Stock Exchange listing and bought a 23% interest in the Pelican Lake horizontal drilling project in western Canada. This project was successful and is still continuing at a maximum production rate of 2,000 bbl/d.

    Multidrug resistant microbes present in the environment are a potential public health risk. In this study, we investigate the presence of New Delhi metallo-β-lactamase 1 (NDM-1) producing bacteria in the 99 water samples in Beijing City, including river water, treated drinking water, raw water samples from the pools and sewage from 4 comprehensive hospitals. For the bla NDM-1 positive isolate, antimicrobial susceptibility testing was further analyzed, and Pulsed Field Gel Electrophoresis (PFGE) was performed to determine the genetic relationship among the NDM-1 producing isolates from sewage and human, as well as the clinical strains without NDM-1. The results indicate that there was a higher isolation of NDM-1 producing Acinetobacter baumannii from the sewage of the hospitals, while no NDM-1 producing isolates were recovered from samples obtained from the river, drinking, or fishpond water. Surprisingly, these isolates were markedly different from the clinical isolates in drug resistance and pulsed field gel electrophoresis profiles, suggesting different evolutionary relationships. Our results showed that the hospital sewage may be one of the diffusion reservoirs of NDM-1 producing bacteria.

  5. Establishment of immortalized human erythroid progenitor cell lines able to produce enucleated red blood cells.

    Full Text Available Transfusion of red blood cells (RBCs is a standard and indispensable therapy in current clinical practice. In vitro production of RBCs offers a potential means to overcome a shortage of transfusable RBCs in some clinical situations and also to provide a source of cells free from possible infection or contamination by microorganisms. Thus, in vitro production of RBCs may become a standard procedure in the future. We previously reported the successful establishment of immortalized mouse erythroid progenitor cell lines that were able to produce mature RBCs very efficiently. Here, we have developed a reliable protocol for establishing immortalized human erythroid progenitor cell lines that are able to produce enucleated RBCs. These immortalized cell lines produce functional hemoglobin and express erythroid-specific markers, and these markers are upregulated following induction of differentiation in vitro. Most importantly, these immortalized cell lines all produce enucleated RBCs after induction of differentiation in vitro, although the efficiency of producing enucleated RBCs remains to be improved further. To the best of our knowledge, this is the first demonstration of the feasibility of using immortalized human erythroid progenitor cell lines as an ex vivo source for production of enucleated RBCs.

  6. Variation in Direct Access to Tests to Investigate Cancer: A Survey of English General Practitioners.

    Directory of Open Access Journals (Sweden)

    Brian D Nicholson

    Full Text Available The 2015 NICE guidelines for suspected cancer recommend that English General Practitioners have direct access to diagnostic tests to investigate symptoms of cancer that do not meet the criteria for urgent referral. We aimed to identify the proportion of GPs in England with direct access to these tests.We recruited 533 English GPs through a national clinical research network to complete an online survey about direct access to laboratory, radiology, and endoscopy tests in the three months leading up to the release of the 2015 NICE guidance. If they had direct access to a diagnostic test, GPs were asked about the time necessary to arrange a test and receive a report. Results are reported by NHS sub-region and, adjusting for sampling, for England as a whole.Almost all GPs reported direct access to x-ray and laboratory investigations except faecal occult blood testing (54%, 95% CI 49-59% and urine protein electrophoresis (89%, 95% CI 84-92%. Fewer GPs had direct access to CT scans (54%, 95% CI 49-59% or endoscopy (colonoscopy 32%, 95% CI 28-37%; gastroscopy 72%, 95% CI 67-77%. There was significant variation in direct access between NHS regions for the majority of imaging tests-for example, from 20 to 85% to MRI. Apart from x-ray, very few GPs (1-22% could access radiology and endoscopy within the timescales recommended by NICE. The modal request to test time was 2-4 weeks for routine radiology and 4-6 weeks for routine endoscopy with results taking another 1-2 weeks.At the time that the 2015 NICE guideline was released, local investment was required to not only provide direct access but also reduce the interval between request and test and speed up reporting. Further research using our data as a benchmark is now required to identify whether local improvements in direct access have been achieved in response to the NICE targets. If alternative approaches to test access are to be proposed they must be piloted comprehensively and underpinned by robust

    Full Text Available The purpose of this study was to identify clinician characteristics associated with higher prescription rates of long-acting injectable (LAI antipsychotics, as well as the sources that influence medical decision-making regarding the treatment of schizophrenia. We surveyed 202 psychiatrists during six regional French conferences (Bordeaux, Lyon, Marseille, Nice, Paris, and Strasbourg. Data on the characteristics of practice, prescription rates of antipsychotic, and information sources about their clinical decisions were collected. Most psychiatrists used second-generation antipsychotics (SGAs, and preferentially an oral formulation, in the treatment of schizophrenia. LAI SGAs were prescribed to 30.4% of schizophrenic patients. The duration and type of practice did not influence the class or formulation of antipsychotics used. The clinicians following the higher percentage of schizophrenic patients were associated with a higher use of LAI antipsychotics and a lower use of oral SGAs. Personal experience, government regulatory approval, and guidelines for the treatment of schizophrenia were the three main contributing factors guiding clinicians’ decision-making regarding the treatment of schizophrenia. The more clinicians follow schizophrenic patients, the more they use LAI antipsychotics. The development of specialized programs with top specialists should lead to better use of LAI antipsychotics in the treatment of schizophrenia.

    To compare the mandibular incisor proclination produced by fixed labial appliances and third generation clear aligners. Patients underwent a course of orthodontic treatment using either fixed labial appliances or clear aligners (Invisalign). Mandibular incisor proclination was measured by comparing pretreatment and near-end treatment lateral cephalograms. Eligibility criteria included adult patients with mild mandibular incisor crowding (clear aligner group. Baseline characteristics were similar for both groups: Fixed appliance mean crowding was 2.1 ± 1.3 mm vs clear aligner mean crowding, 2.5 ± 1.3 mm; pretreatment mean mandibular incisor inclination for the fixed appliance group was 90.8 ± 5.4° vs 91.6 ± 6.4° for the clear aligner group. Fixed appliances produced 5.3 ± 4.3° of mandibular incisor proclination. Clear aligners proclined the mandibular incisors by 3.4 ± 3.2°. The difference between the two groups was not statistically significant (P > .05). There was no difference in the amount of mandibular incisor proclination produced by clear aligners and fixed labial appliances in mild crowding cases.

    2014-06-01

    Full Text Available Fibroblast growth factor 23 (FGF23 is a hormone that is produced by osteocytes and regulates phosphate and vitamin D metabolism through binding to the Klotho-FGF receptor complex. Excessive actions of FGF23 cause several kinds of hypophosphatemic rickets/osteomalacia. Tumor-induced rickets/osteomalacia (TIO is a paraneoplastic syndrome caused by overproduction of FGF23 from the responsible tumors. Because TIO is cured by complete resection of the causative tumors, it is of great clinical importance to locate these tumors. Several imaging methods including skeletal survey by magnetic resonance imaging and octreotide scintigraphy have been used to identify the tumors that cause TIO. However, none of these imaging studies indicate that the detected tumors are actually producing FGF23. Recently, systemic venous sampling was conducted for locating FGF23-producing tumor in suspected patients with TIO and demonstrated that this test might be beneficial to a subset of patient. Further studies with more patients are necessary to establish the clinical utility of venous sampling in patients with TIO.

    The purpose of this study was to verify the clinical-feasibility of additive manufacturing by comparing the accuracy of four different manufacturing methods for metal coping: the conventional lost wax technique (CLWT); subtractive methods with wax blank milling (WBM); and two additive methods, multi jet modeling (MJM), and micro-stereolithography (Micro-SLA). Thirty study models were created using an acrylic model with the maxillary upper right canine, first premolar, and first molar teeth. Based on the scan files from a non-contact blue light scanner (Identica; Medit Co. Ltd., Seoul, Korea), thirty cores were produced using the WBM, MJM, and Micro-SLA methods, respectively, and another thirty frameworks were produced using the CLWT method. To measure the marginal and internal gap, the silicone replica method was adopted, and the silicone images obtained were evaluated using a digital microscope (KH-7700; Hirox, Tokyo, Japan) at 140X magnification. Analyses were performed using two-way analysis of variance (ANOVA) and Tukey post hoc test (α=.05). The mean marginal gaps and internal gaps showed significant differences according to tooth type (Pmanufacturing method (Pmanufacturing methods were within a clinically allowable range, and, thus, the clinical use of additive manufacturing methods is acceptable as an alternative to the traditional lost wax-technique and subtractive manufacturing.

    Users are invited to use the NICE password for AIS authentication. As announced in CNL June-August 2006 (see http://www.cerncourier.com/articles/cnl/3/6/14/1) it is possible to use the NICE username and password to log on to AIS. The procedure is now fully operational and users can themselves reset the AIS password such that the NICE password will be used for authentication required by AIS applications. We strongly recommend CERN users who have a NICE account (this is the case of most users) to do this, with the objective to reduce the number of passwords they need to remember. This can be achieved very easily, directly from the Change Password option on the AIS login (https://aislogin.cern.ch/).

    2016-06-01

    In the UK fewer than 15% of familial hypercholesterolemia (FH) cases are diagnosed, representing a major gap in coronary heart disease prevention. We wished to support primary care doctors within the Medway Clinical Commissioning Group (CCG) to implement NICE guidance (CG71) and consider the possibility of FH in adults who have raised total cholesterol concentrations, thereby improving the detection of people with FH. Utilizing clinical decision support software (Audit+) we developed an FH Audit Tool and implemented a systematic audit of electronic medical records within GP practices, first identifying all patients diagnosed with FH or possible FH and next electronically flagging patients with a recorded total cholesterol of >7.5 mmol L(-1) or LDL-C > 4.9 mmol L(-1) (in adults), for further assessment. After a 2-year period, a nurse-led clinic was introduced to screen more intensely for new FH index cases. We evaluated if these interventions increased the prevalence of FH closer to the expected prevalence from epidemiological studies. The baseline prevalence of FH within Medway CCG was 0.13% (1 in 750 persons). After 2 years, the recorded prevalence of diagnosed FH increased by 0.09% to 0.22% (1 in 450 persons). The nurse advisor programme ran for 9 months (October 2013-July 2014) and during this time, the recorded prevalence of patients diagnosed with FH increased to 0.28% (1 in 357 persons) and the prevalence of patients 'at risk and unscreened' reduced from 0.58% to 0.14%. Our study shows that two simple interventions increased the detection of FH. This systematic yet simple electronic case-finding programme with nurse-led review allowed the identification of new index cases, more than doubling the recorded prevalence of detected disease to 1 in 357 (0.28%). This study shows that primary care has an important role in identifying patients with this condition. © 2015 The Authors. Journal of Evaluation in Clinical Practice published by John Wiley

    2012-10-01

    Increased consumption, larger scale production and more efficient distribution of fresh produce over the past two decades have contributed to an increase in the number of illness outbreaks caused by this commodity. Pathogen contamination of fresh produce may originate before or after harvest, but once contaminated produce is difficult to sanitize. The prospect that some pathogens invade the vascular system of plants and establish "sub-clinical" infection needs to be better understood to enable estimation of its influence upon risk of human illness. Conventional surface sanitation methods can reduce the microbial load, but cannot eliminate pathogens if present. Chlorine dioxide, electrolyzed water, UV light, cold atmospheric plasma, hydrogen peroxide, organic acids and acidified sodium chlorite show promise, but irradiation at 1 kGy in high oxygen atmospheres may prove to be the most effective means to assure elimination of both surface and internal contamination of produce by pathogens. Pathogens of greatest current concern are Salmonella (tomatoes, seed sprouts and spices) and Escherichia coli O157:H7 on leafy greens (spinach and lettuce). This review considers new information on illness outbreaks caused by produce, identifies factors which influence their frequency and size and examines intervention effectiveness. Research needed to increase our understanding of the factors influencing microbial safety of fresh produce is addressed. Copyright © 2012 Elsevier Ltd. All rights reserved.

  16. Should fertility clinics divest themselves of pornography?

    Murphy, Timothy F

    2016-12-01

    Some commentators object to the way in which fertility clinics make pornography available to men as an aid to masturbation when those men produce sperm for evaluation, storage or IVF. These objections typically rely on claims that pornography is generally harmful to women, unnecessary and dissociates sexual acts from conception. In light of these objections, certain commentators want fertility clinics to divest themselves of pornography, but these objections to pornography are not morally convincing. In general, pornography can have psychological value to men masturbating 'on demand' in clinical contexts. Not all erotica must, either, work to the disadvantage of women in its means of production or social effects. Moreover, the sexuality expressed in masturbation has a value of its own, and conception apart from sexual intercourse is morally defensible on its own. Divestment from pornography would do little to constrain the putative harms of pornography because clinics consume only a fractional amount of the total amount of pornography available. The provision of pornography is a defensible clinical practice, even if it is not absolutely necessary to all men in producing a sperm sample important to their fertility or their interests in donating gametes.

  18. The expression of antibiotic resistance genes in antibiotic-producing bacteria.

    Science.gov (United States)

    Mak, Stefanie; Xu, Ye; Nodwell, Justin R

    2014-08-01

    Antibiotic-producing bacteria encode antibiotic resistance genes that protect them from the biologically active molecules that they produce. The expression of these genes needs to occur in a timely manner: either in advance of or concomitantly with biosynthesis. It appears that there have been at least two general solutions to this problem. In many cases, the expression of resistance genes is tightly linked to that of antibiotic biosynthetic genes. In others, the resistance genes can be induced by their cognate antibiotics or by intermediate molecules from their biosynthetic pathways. The regulatory mechanisms that couple resistance to antibiotic biosynthesis are mechanistically diverse and potentially relevant to the origins of clinical antibiotic resistance. © 2014 John Wiley & Sons Ltd.

    The plasmid-mediated quinolone resistance qnr genes in clinical isolates in adults have been described in different countries; however, the frequency of their occurrence has not been detected in pediatric patients. A total of 410 clinical isolates of Klebsiella pneumoniae, identified as producers of an extended-spectrum beta-lactamase (ESBL), or AmpC beta-lactamase, were collected from five children's hospitals in China during 2005-2006. The isolates were screened for the presence of the qnrA, qnrB, and qnrS genes, and then the harboring qnr gene isolates were detected for a bla gene coding for the TEM, SHV, CTX-M, and plasmid-mediated ampC gene by a PCR experiment. Ninety-two isolates (22.7%) were positive for the qnr gene, including 10 of qnrA (2.4%), 25 of qnrB (6.1%), and 62 of qnrS (15.1%). Eighty-one of the 92 (88.0%) qnr-positive isolates carried at least one bla gene for TEM, SHV, CTX-M, or DHA-1. The ciprofloxacin resistance increased 16-256-fold and oflaxacin resistance increased 2-32-fold in transconjugants, respectively. These results indicated that the plasmid-mediated qnr quinolone resistance gene was qnrS, followed by qnrB and qnrA. Most of the isolates also carried a bla gene coding ESBL or ampC gene coding DHA-1 among Klebsiella pneumoniae isolated from Chinese pediatric patients.

    Carbapenemase-producing Enterobacteriaceae (CPE) strains have been increasingly reported in Belgium. We aimed to determine the proportion of CPE among Enterobacteriaceae isolated from hospitalised patients and community outpatients in Belgium in 2015. For the hospitalised patients, the results were compared to a previous similar survey performed in the same hospitals in 2012. Twenty-four hospital-based and 10 private laboratories collected prospectively 200 non-duplicated Enterobacteriaceae isolates from clinical specimens. All isolates were screened locally by carbapenem disk diffusion using European Committee on Antimicrobial Susceptibility Testing methodology. Putative CPE strains with inhibition zone diameters below the screening breakpoints were referred centrally for confirmation of carbapenemase production. From September to November 2015, we found a proportion of clinical CPE of 0.55% (26/4,705) and of 0.60% (12/1,991) among hospitalised patients and among ambulatory outpatients respectively. Klebsiella pneumoniae (26/38) and OXA-48-like carbapenemase (28/38) were the predominant species and enzyme among CPE. One OXA-48-producing Escherichia coli isolated from a hospital was found carrying plasmid-mediated MCR-1 colistin resistance. Compared with the 2012 survey, we found a significant increased proportion of clinical CPE (0.55% in 2015 vs 0.25% in 2012; p = 0.02) and an increased proportion of hospitals (13/24 in 2015 vs 8/24 in 2012) with at least one CPE detected. The study results confirmed the concerning spread of CPE including a colistin-resistant MCR-1 producer in hospitals and the establishment of CPE in the community in Belgium.

    9 9 m Tc labelled 2-methoxy-isobutyl-isonitrile(MIBI) has been known as an imaging agent for myocardial perfusion. This radiopharmaceutical preparation gives the same satisfactory result as Thallium- 2 10TI, and presumably could replace 2 01TI because of same advantages. MIBI kit was formulated from MIBI ligand produced by RPC-BATAN which has been characterized and tested for quality. The formula used in this research referred to the formula of imported product(Cardiolite, MIBI kit produced by Dupont), and the quality control testing was performed by comparing some parameters to the imported product. The parameters used for QC testing were radiochemical purity, biodistribution in nice and heart imaging in human volunteer using gamma camera. The result of the experiment showed that the radiochemical purity was 95 % in average, biodistribution in heart to liver gave the ratio of 0.67, 1.5, and 2.53 respectively at 10, 30 and 60 minutes after injection. The result of clinical testing in some volunteers gave contrast images as good as given by Cardiolite. The optimum condition of freeze drying has been found, and the kit can be used for more than 6 months

    : Emergency medicine is widely recognised as an intense specialty. Interruptions are known to derail thoughts, increasing cognitive load and result in longer periods before deep thought is re-established. Although approachability and warmth are regarded as important factors in clinicians we wondered what impact these characteristics had on the number of interruptions. A team of 6 medical students were trained in the use of abespoke tool to record shop floor activities. Over 4 months we conducted 100 hours of minute by minute time and motion study of emergency medicine consultants during their clinical shifts, and noted how often they were interrupted. At the end of shifts the assessors were asked a set of qualitative questions on the behaviour and attitudes of the consultants. These questions were completed in seclusion and in an anonymous format, to minimise the chance of bias/influence. QUESTIONS INCLUDED: 'How friendly was the consultant with other staff?' 'How friendly was this consultant with patients?' And, 'How would you rate this consultant's 'general positivity'?'We then assessed whether consultants that scored 'higher' inthese areas were more likely to be interrupted. Our hypothesis was that consultants who were more friendly were less intimidating for juniors and nurses to approach with questions, and so may suffer from an increase in cognitive load due to being interrupted and questioned more frequently than consultants who were felt to be less approachable.We found that consultants who scored 1(highest) in friendliness had an average of 7.38 interruptions per hour, compared to consultants who scored 3 or greater, who had an average of 3.59. Our average interruptions were close to those found in previous publications (between 6 and 9 interruptions per hour), however there was a large amount of inter-consultant variability, with one consultant during one shift being interrupted over 12 times per hour on average.

    The number of Clinical Practice Guidelines (CPG) to help in making clinical decisions is increasing. However, there is currently a lack of CPG for Obsessive-Compulsive Disorder that take into account the requirements and expectations of the patients. The aim of the present study was to determine whether recommendations of the NICE guideline, "Obsessive-compulsive disorder: core interventions in the treatment of obsessive-compulsive disorder and body dysmorphic disorder" agrees with the needs and preferences of patients diagnosed with OCD in the mental health service. Two focal groups were formed with a total of 12 participants. They were asked about the impact of the disorder in their lives, their experiences with the mental health services, their satisfaction with treatments, and about their psychological resources. Preferences and needs were compared with the recommendations of the guidelines, and to facilitate their analysis, they were classified into four topics: information, accessibility, treatments, and therapeutic relationship. The results showed a high agreement between recommendations and patients preferences, particularly as regards high-intensity psychological interventions. Some discrepancies included the lack of prior low-intensity psychological interventions in mental health service, and the difficulty of rapid access the professionals. There is significant concordance between recommendations and patients preferences and demands, which are only partially responded to by the health services.

  6. Hybrid antibiotics - clinical progress and novel designs.

    Parkes, Alastair L; Yule, Ian A

    2016-07-01

    There is a growing need for new antibacterial agents, but success in development of antibiotics in recent years has been limited. This has led researchers to investigate novel approaches to finding compounds that are effective against multi-drug resistant bacteria, and that delay onset of resistance. One such strategy has been to link antibiotics to produce hybrids designed to overcome resistance mechanisms. The concept of dual-acting hybrid antibiotics was introduced and reviewed in this journal in 2010. In the present review the authors sought to discover how clinical candidates described had progressed, and to examine how the field has developed. In three sections the authors cover the clinical progress of hybrid antibiotics, novel agents produced from hybridisation of two or more small-molecule antibiotics, and novel agents produced from hybridisation of antibiotics with small-molecules that have complementary activity. Many key questions regarding dual-acting hybrid antibiotics remain to be answered, and the proposed benefits of this approach are yet to be demonstrated. While Cadazolid in particular continues to progress in the clinic, suggesting that there is promise in hybridisation through covalent linkage, it may be that properties other than antibacterial activity are key when choosing a partner molecule.

    Full Text Available Objective: This study aimed to determine the prevalence and assess antimicrobial susceptibility of extended- spectrum β-lactamase-producing Escherichia coli isolated from clinical specimens of patients at hospitals in Khartoum State, Sudan.Methods: During April to August 2011, a total of 232 E. coli isolates were collected from various clinical specimens of patients. Isolates were identified, tested for antimicrobial susceptibility and screened for ESBL production as per standard methods. The double-disk diffusion method was used to confirm ESBL production using antimicrobial disks of ceftazidime (30 μg, cefotaxime (30 μg, with or without clavulanic acid (10 μg. A zone difference of >5 mm between disks was considered indicative of ESBL production.Results: Out of 232 E. coli isolates, 70 (30.2% were found to be positive for ESBL by the applied phenotypic methods. ESBL-producing isolates yielded high resistance rates for trimethoprim-sulfamethoxazole (98.6%, tetracycline (88.6%, nalidixic acid (81.4% and ciprofloxacin (81.4%. The highest antimicrobial activities of ESBL-producing isolates were observed for amikacin (95.7%, followed by tobramicin (74.3% and nitrofurantoin (68.6%. Resistance to quinolones, aminoglycosides, trimethoprim-sulfamethoxazole, tetracycline, nitrofurantoin and chloramphenicol was higher in ESBL than non-ESBL isolates (p<0.05. The frequency of ESBL-producing isolates varied among hospitals (18.2% to 45.1%, although a high prevalence was recorded as 45.1% at Khartoum Teaching Hospital. Wound specimens were the most common source of ESBL-producing isolates. The proportion of ESBL-producing E. coli did not differ significantly between adults and children (31% vs. 27%.Conclusion: The prevalence of ESBL-producing E. coli detected in this study is of great concern, which requires sound infection control measures including antimicrobial management and detection of ESBL-producing isolates.

    The purpose of this study was to evaluate the impact of the employment of additional podiatry staff on patients with diabetes attending a community-based podiatry service. An audit was conducted to evaluate the intervention of two additional podiatry staff. All patients with diabetes referred to and attending community podiatry services in a specified area in the Republic of Ireland between June 2011 and June 2012 were included. The service was benchmarked against the UK gold standard outlined in the 'Guidelines on prevention & management of foot problems in Type 2 Diabetes' by the National Institute of Clinical Excellence (NICE). Process of care measures addressed were the number of patients with diabetes receiving treatment and the waiting times of patients with diabetes from referral to initial review. An increase in the number of patients with diabetes receiving treatment was seen in all risk categories (ranging from low risk to the emergency foot). Waiting times for patients with diabetes decreased post-intervention but did not reach the targets outlined in the NICE guidelines. The average time from referral to initial review of patients with an emergency diabetic foot was 37 weeks post-intervention. NICE guidelines recommend that these patients are seen within 24 hours. During the life cycle of this audit, increased numbers of patients were treated and waiting times for patients with diabetes were reduced. An internal re-organisation of the services coincided with the commencement of the additional staff. The improvements observed were due to the effects of a combination of additional staff and service re-organisation. Efficient organisation of services is key to optimal performance. Continued efforts to improve services are required to reach the standards outlined in the NICE guidelines.

    To conduct an audit of insulin pump therapy in the UK after the issue of guidelines for the use of continuous subcutaneous insulin infusion by NICE in 2008 (Technology Appraisal 151). All centres in the UK, providing pump services to children and young people were invited to participate in an online audit. Audit metrics were aligned to NICE Technology Appraisal 151 and an electronic data collection tool was used. Of the 176 UK centres identified as providing pump services, 166 (94.3%) participated in the study. A total of 5094 children and young people were identified as using continuous subcutaneous insulin infusion (19% of all paediatric patients with Type 1 diabetes), with a median (range) of 16.9 (0.67-69.4)% per centre. Units had a median of 0.58 consultant sessions, 0.43 full-time equivalent diabetic specialist nurses, and 0.1 full-time equivalent dieticians delivering the pump service. The majority of this time was not formally funded. Families could access 24-h clinical and technical support (83% units), although the delivery varied between consultant, diabetic specialist nurse and company representatives. Only 53% of units ran, or accessed, structured education programmes for continuous subcutaneous insulin infusion use. Most units (86%) allowed continuous subcutaneous insulin infusion use for paediatric inpatients, but only 56% had written guidelines for this scenario. Nine percent of units had encountered funding refusal for a patient fulfilling NICE (Technology Appraisal 151) criteria. The number of children and young people on continuous subcutaneous insulin infusion therapy is consistent with numbers estimated by NICE. There is a worrying lack of funded healthcare professional time. The audit also identified gaps in the provision of structured education and absence of written inpatient guidelines. © 2015 The Authors. Diabetic Medicine © 2015 Diabetes UK.

  12. Comparison of the incidence of oncogenic transformation produced by x-rays, misonidazole, and chemotherapy agents

    An established line of mouse fibroblasts (10T1/2 cells) cultured in vitro was used to compare the incidence of oncogenic transformation produced by x rays, the hypoxic cell radiosensitizer misonidazole, and a range of commonly used chemotherapy agents. A 3-day exposure to misonidazole at a concentration obtainable during treatment produced an incidence of transformation similar to that of about 50 rad. When chemotherapy agents were tested at concentrations comparable to those used clinically and matched to produce similar cell killing, the incidence of transformation varied widely: some agents, such as vincristine, did not produce transformation at a level detectable above background, while others, such as cis-plantinum, appear to be potent carcinogens and produce transformation at a rate orders of magnitude higher than that achieved with x rays

    Scintigrams were made using sup(99m)Tc-Sn-colloid, sup(99m)Tc-pyrophosphate, sup(99m)Tc-EDTA and sup(99m)Tc-albumin prepared by electrolysis, and a clinical evaluation was attempted. No side effects were recognized in 228 cases, therefore the object of this study could be attained. Future study was thought to be necessary because the pictures were somewhat indistinct. However, each sup(99m)Tc-labeled compound could be prepared very easily and was extremely convenient for daily use. sup(99m)Tc- is a nuclide which has many advantages for use with scintigrams. More useful sup(99m)Tc-labeled compounds will be explored in the future and is expected that electrolysis has many possibilities for use in the preparation of sup(99m)Tc-labeled compounds.

    Electroencephalography (EEG) remains an essential diagnostic tool for people with epilepsy (PWE). The International Federation of Clinical Neurophysiology produces new guidelines as an educational service for clinicians to address gaps in knowledge in clinical neurophysiology. The current guideline was prepared in response to gaps present in epilepsy-related neurophysiological assessment and is not intended to replace sound clinical judgement in the care of PWE. Furthermore, addressing specific pathophysiological conditions of the brain that produce epilepsy is of primary importance though is beyond the scope of this guideline. Instead, our goal is to summarize the scientific evidence for the utility of EEG when diagnosing and monitoring PWE. Copyright © 2018 International Federation of Clinical Neurophysiology.

    A recombinant measles virus (MV) expressing the sodium iodide symporter (NIS) is being considered for therapy of advanced multiple myeloma. Auger electrons selectively damage cells in which the isotope decays. We hypothesized that the Auger electron emitting isotope 125 I can be used to control viral proliferation. MV was engineered to express both carcinoembryonic antigen and NIS (MV-NICE). Cells were infected with MV-NICE and exposed to 125 I with appropriate controls. MV-NICE replication in vitro is inhibited by the selective uptake of 125 I by cells expressing NIS. Auger electron damage is partly mediated by free radicals and abrogated by glutathione. In myeloma xenografts, control of MV-NICE with 125 I was not possible under the conditions of the experiment. MV-NICE does not replicate faster in the presence of radiation. Auger electron emitting isotopes effectively stop propagation of MV vectors expressing NIS in vitro. Additional work is necessary to translate these observations in vivo

    We report in this study the frequency of Streptomyces strains to produce macrolide-lincosamide-streptogramin (MLS) antibiotics isolated from Cuban soils. The screening assay is based on the induction of MLS-resistance phenotype in a clinical isolated strain of Staphylococcus aureus S-18. Our results suggest that of 800 Streptomyces strains isolated from different soil samples, 6% were positives in the screening test used. The ferralitic red soil from Pinar del Río (north) provided the major percentage (3.6%) of MLS producing strains. The other soil samples tested belonging to Guira de Melena and Bauta in Havana, Matanzas City, Topes De Collantes (Villa Clara), and Soroa Mountains (Pinar del Rio) hill reached very low percentages.

    Breast, cervical and colorectal cancers are the three most frequent cancers in women, while lung, prostate and colorectal cancers are the most frequent in men. Much attention has been given to the economic evaluation of pharmaceuticals for treatment of cancer by the National Institute for Health and Care Excellence (NICE) in the UK and similar authorities internationally, while economic analysis developed for other types of anti-cancer interventions, including radiotherapy and surgery, are less common. Our objective was to review methods used in published cost-effectiveness studies evaluating radiotherapy for breast, cervical, colorectal, head and neck and prostate cancer, and to compare the economic evaluation methods applied with those defined in the guidelines used by the NICE technology appraisal programme. A systematic search of seven databases (MEDLINE, EMBASE, CDSR, NHSEED, HTA, DARE, EconLit) as well as research registers, the NICE website and conference proceedings was conducted in July 2012. Only economic evaluations of radiotherapy interventions in individuals diagnosed with cancer that included quality-adjusted life-years (QALYs) or life-years (LYs) were included. Included studies were appraised on the basis of satisfying essential, preferred and UK-specific methods requirements, building on the NICE Reference Case for economic evaluations and on other methods guidelines. A total of 29 studies satisfied the inclusion criteria (breast 14, colorectal 2, prostate 10, cervical 0, head and neck 3). Only two studies were conducted in the UK (13 in the USA). Among essential methods criteria, the main issue was that only three (10%) of the studies used clinical-effectiveness estimates identified through systematic review of the literature. Similarly, only eight (28%) studies sourced health-related quality-of-life data directly from patients with the condition of interest. Other essential criteria (e.g. clear description of comparators, patient group indication

    2016-01-01

    Background The 2015 NICE guidelines for suspected cancer recommend that English General Practitioners have direct access to diagnostic tests to investigate symptoms of cancer that do not meet the criteria for urgent referral. We aimed to identify the proportion of GPs in England with direct access to these tests. Methods We recruited 533 English GPs through a national clinical research network to complete an online survey about direct access to laboratory, radiology, and endoscopy tests in the three months leading up to the release of the 2015 NICE guidance. If they had direct access to a diagnostic test, GPs were asked about the time necessary to arrange a test and receive a report. Results are reported by NHS sub-region and, adjusting for sampling, for England as a whole. Results Almost all GPs reported direct access to x-ray and laboratory investigations except faecal occult blood testing (54%, 95% CI 49–59%) and urine protein electrophoresis (89%, 95% CI 84–92%). Fewer GPs had direct access to CT scans (54%, 95% CI 49–59%) or endoscopy (colonoscopy 32%, 95% CI 28–37%; gastroscopy 72%, 95% CI 67–77%). There was significant variation in direct access between NHS regions for the majority of imaging tests—for example, from 20 to 85% to MRI. Apart from x-ray, very few GPs (1–22%) could access radiology and endoscopy within the timescales recommended by NICE. The modal request to test time was 2–4 weeks for routine radiology and 4–6 weeks for routine endoscopy with results taking another 1–2 weeks. Conclusion At the time that the 2015 NICE guideline was released, local investment was required to not only provide direct access but also reduce the interval between request and test and speed up reporting. Further research using our data as a benchmark is now required to identify whether local improvements in direct access have been achieved in response to the NICE targets. If alternative approaches to test access are to be proposed they must be

    The National Institute of Care Excellence (NICE) 2007 guidance CG54, on urinary tract infection (UTI) in children, states that clinicians should use urgent microscopy and culture as the preferred method for diagnosing UTI in the hospital setting for severe illness in children under 3 years old and from the GP setting in children under 3 years old with intermediate risk of severe illness. NICE also recommends that all 'infants and children with atypical UTI (including non-Escherichia coli infections) should have renal imaging after a first infection'. We surveyed all microbiology laboratories in England with Clinical Pathology Accreditation to determine standard operating procedures (SOPs) for urgent microscopy, culture and reporting of children's urine and to ascertain whether the SOPs facilitate compliance with NICE guidance. We undertook a computer search in six microbiology laboratories in south-west England to determine urine submissions and urine reports in children under 3 years. Seventy-three per cent of laboratories (110/150) participated. Enterobacteriaceae that were not E. coli were reported only as coliforms (rather than non-E. coli coliforms) by 61% (67/110) of laboratories. Eighty-eight per cent of laboratories (97/110) provided urgent microscopy for hospital and 54% for general practice (GP) paediatric urines; 61% of laboratories (confidence interval 52-70%) cultured 1 μl volume of urine, which equates to one colony if the bacterial load is 106 c.f.u. l(-1). Only 22% (24/110) of laboratories reported non-E. coli coliforms and provided urgent microscopy for both hospital and GP childhood urines; only three laboratories also cultured a 5 μl volume of urine. Only one of six laboratories in our submission audit had a significant increase in urine submissions and urines reported from children less than 3 years old between the predicted pre-2007 level in the absence of guidance and the 2008 level following publication of the NICE guidance.

    Full Text Available Ramin Safakish Allevio Pain Management Clinic, Toronto, ON, Canada Abstract: Lower back pain (LBP is a global public health issue and is associated with substantial financial costs and loss of quality of life. Over the years, different literature has provided different statistics regarding the causes of the back pain. The following statistic is the closest estimation regarding our patient population. The sacroiliac (SI joint pain is responsible for LBP in 18%–30% of individuals with LBP. Quadrapolar™ radiofrequency ablation, which involves ablation of the nerves of the SI joint using heat, is a commonly used treatment for SI joint pain. However, the standard Quadrapolar radiofrequency procedure is not always effective at ablating all the sensory nerves that cause the pain in the SI joint. One of the major limitations of the standard Quadrapolar radiofrequency procedure is that it produces small lesions of ~4 mm in diameter. Smaller lesions increase the likelihood of failure to ablate all nociceptive input. In this study, we compare the standard Quadrapolar radiofrequency ablation technique to a modified Quadrapolar ablation technique that has produced improved patient outcomes in our clinic. The methodology of the two techniques are compared. In addition, we compare results from an experimental model comparing the lesion sizes produced by the two techniques. Taken together, the findings from this study suggest that the modified Quadrapolar technique provides longer lasting relief for the back pain that is caused by SI joint dysfunction. A randomized controlled clinical trial is the next step required to quantify the difference in symptom relief and quality of life produced by the two techniques.

    The characteristics of patients with recurrent bacteraemia caused by extended-spectrum β-lactamase (ESBL)-producing Escherichia coli or Klebsiella pneumoniae (EK) are rarely described. Flomoxef belongs to the cephamycins group and demonstrates in vitro activity against ESBL-producing organisms. Whether flomoxef may be used for the treatment of such infections remains controversial. This retrospective case-control study enrolled adult patients who had bacteraemia caused by ESBL-EK during 2005-2011. Case patients were those who had more than one episode of ESBL-EK bacteraemia. Controls were those who were matched for age and interval time of blood sampling and had only one episode of ESBL-EK bacteraemia with subsequent bacteraemia episodes caused by other non-ESBL-EK bacteria. Pulsed-field gel electrophoresis and microbiologic profiles of the initial and subsequent ESBL-EK isolates were analysed. During the study period, 424 patients were found to have at least one positive blood culture after the first ESBL-EK bacteraemia episode, and 67 (15.8%) had a second episode of ESBL-EK bacteraemia. Bacteraemia resulting from vascular catheter-related infection (odds ratio, 3.24; 95% confidence interval, 1.31-8.05), and definitive therapy with flomoxef (odds ratio, 2.99; 95% confidence interval, 1.10-8.15) were both independent risk factors for the recurrence. Among the 56 patients with available ESBL-EK isolates for analysis, 38 (67.8%) were infected by genetically similar strains. In three of these 38 recurrent ESBL-EK bacteraemia cases caused by an identical strain, the minimum inhibitory concentrations of carbapenem for the subsequent K. pneumoniae isolates were fourfold or higher than the initial isolates. Recurrent bacteraemia was not uncommon in our patients with ESBL-EK bacteraemia, and most of the episodes were caused by identical strains.

    The US electric industry will be deregulated (or substantially re-regulated) within 5 years. Several states, including California, Rhode Island, and New Hampshire, already have passed legislation to introduce competition into the electric markets before the year 2000. As this trend sweeps across the country, the resulting competitive market for generation will reward the lowest cost producers and force high cost producers out of the market. As a result, at least in the short run, it may be very difficult for new power plants employing Clean Coal Technologies (CCTs) to compete. This paper discusses a producer`s perspective of the new competitive market, and suggests several short and long term strategies and niches for CCTs.

    The development of information technology has resulted in its penetration into every area of clinical research. Various clinical systems have been developed, which produce increasing volumes of clinical data. However, saving, exchanging, querying, and exploiting these data are challenging issues. The development of Extensible Markup Language (XML) has allowed the generation of flexible information formats to facilitate the electronic sharing of structured data via networks, and it has been used widely for clinical data processing. In particular, XML is very useful in the fields of data standardization, data exchange, and data integration. Moreover, ontologies have been attracting increased attention in various clinical fields in recent years. An ontology is the basic level of a knowledge representation scheme, and various ontology repositories have been developed, such as Gene Ontology and BioPortal. The creation of these standardized repositories greatly facilitates clinical research in related fields. In this chapter, we discuss the basic concepts of XML and ontologies, as well as their clinical applications.

    The manufacturer of olaratumab (Lartruvo ® ), Eli Lilly & Company Limited, submitted evidence for the clinical and cost effectiveness of this drug, in combination with doxorubicin, for untreated advanced soft tissue sarcoma (STS) not amenable to surgery or radiotherapy, as part of the National Institute for Health and Care Excellence (NICE) Single Technology Appraisal process. The Peninsula Technology Assessment Group, commissioned to act as the Evidence Review Group (ERG), critically reviewed the company's submission. Clinical effectiveness evidence for the company's analysis was derived from an open-label, randomised controlled trial, JGDG. The analysis was based on a partitioned survival model with a time horizon of 25 years, and the perspective was of the UK National Health Service (NHS) and Personal Social Services. Costs and benefits were discounted at 3.5% per year. Given the available evidence, olaratumab is likely to meet NICE's end-of-life criteria. To improve the cost effectiveness of olaratumab, the company offered a discount through a Commercial Access Agreement (CAA) with the NHS England. When the discount was applied, the mean base-case and probabilistic incremental cost-effectiveness ratios (ICERs) for olaratumab plus doxorubicin versus the standard-of-care doxorubicin were £46,076 and £47,127 per quality-adjusted life-year (QALY) gained, respectively; the probability of this treatment being cost effective at the willingness-to-pay threshold of £50,000 per QALY gained, applicable to end-of-life treatments, was 0.54. The respective ICERs from the ERG's analysis were approximately £60,000/QALY gained, and the probability of the treatment being cost effective was 0.21. In August 2017, the NICE Appraisal Committee recommended olaratumab in combination with doxorubicin for this indication for use via the UK Cancer Drugs Fund under the agreed CAA until further evidence being collected in the ongoing phase III trial-ANNOUNCE-becomes available in

    The Shiga-toxin producing Escherichia coli (STEC) may cause serious illness in human. Here we analyze O26:H11 strains known to be among the most reported STEC strains causing human infections. Genetic characterization of strains isolated from animal, food, and clinical specimens in Argentina showed that most carried either stx1a or stx2a subtypes. Interestingly, stx2a-positive O26:H11 rarely isolated from cattle in other countries showed to be an important proportion of O26:H11 strains circulating in cattle and food in our region. Seventeen percent of the isolates harbored more than one gene associated with antimicrobial resistance. In addition to stx, all strains contained the virulence genes eae-β, tir, efa, iha, espB, cif, espA, espF, espJ, nleA, nleB, nleC, and iss; and all except one contained ehxA, espP, and cba genes. On the other hand, toxB and espI genes were exclusively observed in stx2-positive isolates, whereas katP was only found in stx1a-positive isolates. Our results show that O26:H11 STEC strains circulating in Argentina, including those isolated from humans, cattle, and meat products, present a high pathogenic potential, and evidence that cattle can be a reservoir of O26:H11 strains harboring stx2a.

    The Heart Rhythm Society (HRS) has been developing clinical practice documents in collaboration and partnership with other professional medical societies since 1996. The HRS formed a Scientific and Clinical Documents Committee (SCDC) with the sole purpose of managing the development of these documents from conception through publication. The SCDC oversees the process for developing clinical practice documents, with input and approval from the HRS Executive Committee and the Board of Trustees. As of May 2017, the HRS has produced more than 80 publications with other professional organizations. This process manual is produced to publicly and transparently declare the standards by which the HRS develops clinical practice documents, which include clinical practice guidelines, expert consensus statements, scientific statements, clinical competency statements, task force policy statements, and proceedings statements. The foundation for this process is informed by the Institute of Medicine's standards for developing trustworthy clinical practice guidelines; the new criteria from the National Guidelines Clearinghouse, effective June 2014; SCDC member discussions; and a review of guideline policies and methodologies used by other professional organizations.

    Breast cancer is the most common cancer affecting European women and the leading cause of cancer-related death. A total of 15-20% of women who develop breast cancer have a family history and 5-10% a true genetic predisposition. The identification and screening of women at increased risk may allow early detection of breast cancer and improve prognosis. We established a family risk assessment clinic in May 2005 to assess and counsel women with a family history of breast cancer, to initiate surveillance, and to offer risk-reducing strategies for selected high-risk patients. Patients at medium or high risk of developing breast cancer according to NICE guidelines were accepted. Family history was determined by structured questionnaire and interview. Lifetime risk of developing breast cancer was calculated using Claus and Tyrer-Cuzick scoring. Risk of carrying a breast cancer-related gene mutation was calculated using the Manchester system. One thousand two hundred and forty-three patients have been referred. Ninety-two percent were at medium or high risk of developing breast cancer. Formal assessment of risk has been performed in 368 patients, 73% have a high lifetime risk of developing breast cancer, and 72% a Manchester score >or=16. BRCA1\\/2 mutations have been identified in 14 patients and breast cancer diagnosed in two. Our initial experience of family risk assessment has shown there to be a significant demand for this service. Identification of patients at increased risk of developing breast cancer allows us to provide individuals with accurate risk profiles, and enables patients to make informed choices regarding their follow-up and management.

  10. Clinical benefits of tight glycaemic control: focus on the intensive care unit.

    While stress hyperglycaemia has traditionally been regarded as an adaptive, beneficial response, it is clear that hyperglycaemia and hypoglycaemia are associated with increased risk of death in critically ill intensive care unit (ICU) patients. Recent studies on blood-glucose control failed to fully clarify whether this association is causal. Early proof-of-concept single-centre randomised controlled studies found that maintaining normoglycaemia by intensive insulin therapy, as compared with tolerating hyperglycaemia as an adaptive response, improved patient outcome. However, recent large multicentre studies VISEP, GLUCONTROL and NICE-SUGAR) could not confirm this survival benefit. Methodological disparity in the execution of the complex intervention of tight glycaemic control may have contributed significantly to the contradicting results. First, different target ranges for blood glucose were used in the control group of the GLUCONTROL and 'Normoglycemia in intensive care evaluation and survival using glucose algorithm' regulation' (NICE-SUGAR) studies. Second, problems to steer blood-glucose levels within target range in the intervention group resulted in a significant overlap of the treatment groups. Third, allowing inaccurate blood-glucose measurement devices, in combination with different blood sampling sites and types of infusion pumps, may have led to unnoticed swings in blood-glucose levels. Fourth, the level of expertise of the intensive care nurses with the therapy may have been variable due to low number of study patients per centre. Finally, the studies on tight blood-glucose control were done with vastly different nutritional and end-of-life strategies. The currently available studies do not allow to confidently recommend one optimal target for glucose in heterogeneous ICU patient groups and settings. Provided that adequate devices for blood-glucose measurement and insulin administration are available, together with an extensive experience of the

    Full Text Available Reform in the South African healthcare and educational system were characterized by the ideals that the country needs to produce independent, critical thinkers. Nurses need to cope with diversity in a more creative way, defining their role in a complex, uncertain, rapidly changing health care environment. Quality clinical judgement is therefore imperative as an identified characteristic of newly qualified professional nurses. The objective of this study was to explore and describe clinical judgement through various data sources and review of literature to clarify the meaning and promote a common understanding through formulating the characteristics and developing a connotative (theoretical definition of the concept. An explorative, descriptive qualitative design was used to discover the complexity and meaning of the phenomenon. Multiple data sources and search strategies were used, for the time frame 1982—2013. A concept analysis was used to arrive at a theoretical definition of the concept of ‘clinical judgement’ as a complex cognitive skill to evaluate patient needs, adaption of current treatment protocols as well as new treatment strategies, prevention of adverse side effects through being proactive rather than reactive within the clinical nursing environment. The findings emphasized clinical judgement as skill within the clinical nursing environment, thereby improving autonomous and accountable nursing care. These findings will assist nurse leaders and clinical nurse educators in developing a teaching-learning strategy to promote clinical judgement in undergraduate nursing students, thereby contributing to the quality of nursing care.

  12. Psl Produced by Mucoid Pseudomonas aeruginosa Contributes to the Establishment of Biofilms and Immune Evasion.

    Despite years of research and clinical advances, chronic pulmonary infections with mucoid Pseudomonas aeruginosa remain the primary concern for cystic fibrosis patients. Much of the research on these strains has focused on the contributions of the polysaccharide alginate; however, it is becoming evident that the neutral polysaccharide Psl also contributes to biofilm formation and the maintenance of chronic infections. Here, we demonstrate that Psl produced by mucoid strains has significant roles in biofilm structure and evasion of immune effectors. Though mucoid strains produce less Psl than nonmucoid strains, the Psl that is produced is functional, since it mediates adhesion to human airway cells and epithelial cell death. Additionally, Psl protects mucoid bacteria from opsonization and killing by complement components in human serum. Psl production by mucoid strains stimulates a proinflammatory response in the murine lung, leading to reduced colonization. To determine the relevance of these data to clinical infections, we tested Psl production and biofilm formation of a panel of mucoid clinical isolates. We demonstrated three classes of mucoid isolates, those that produce Psl and form robust biofilms, those that did not produce Psl and have a poor biofilm phenotype, and exopolysaccharide (EPS) redundant strains. Collectively, these experimental results demonstrate that Psl contributes to the biofilm formation and immune evasion of many mucoid strains. This is a novel role for Psl in the establishment and maintenance of chronic pulmonary infections by mucoid strains. IMPORTANCE Cystic fibrosis patients are engaged in an ongoing battle against chronic lung infections by the bacterium Pseudomonas aeruginosa One key factor contributing to the maintenance of chronic infections is the conversion to a mucoid phenotype, where the bacteria produce copious amounts of the polysaccharide alginate. Once the bacteria become mucoid, existing treatments are poorly effective. We

    Panton-Valentine leukocidin (PVL)-producing Staphylococcus aureus results in leukocyte destruction and tissue necrosis (Pediatric Dermatology 2007;24:401). It can be associated with a spectrum of clinical manifestations that range from localized staphylococcal skin infections to sometimes severe necrotizing pneumonia (Clin Infect Dis 1999;29:1128). We report a case of four siblings, three brothers whose atopic dermatitis was complicated by cutaneous lesions and furunculosis, while their 21-month-old sister had a fatal PVL positive staphylococcal pneumonia.

    Alpha-fetoprotein is a well-known tumor marker in the screening and follow-up of hepatocellular carcinoma. In Taiwanese society, a high prevalence of hepatitis and hepatoma and elevation of alpha-fetoprotein associated with liver function impairment usually suggested clinics undertake further examination for liver or genital tumor. We report the case of 45-year-old man who was found to have an alpha-fetoprotein-producing esophageal adenocarcinoma with an initial presentation of liver function impairment and rapid elevation of alpha-fetoprotein. Esophageal cancer was diagnosed via endoscope and a biopsy proved the presence of adenocarcinoma. A small endoscopic biopsy specimen failed to identify the alpha-fetoprotein positive tumor cell. Esophagectomy was performed and histopathological study of surgical specimen revealed grade II adenocarcinoma with regional metastatic lymphadenopathy. Immunohistochemical study was focal positive for alpha-fetoprotein. Serum alpha-fetoprotein declined transiently after esophagectomy and fluctuation of alpha-fetoprotein level was noted during the treatment with adjuvant chemotherapy. Finally, 19 months after the operation, the patient died due to multiple organ metastases with multiple organ failure. Thus, a small specimen for upper endoscopy may not be sufficient in the presence of alpha-fetoprotein-producing adenocarcinoma. Monitoring of serum alpha-fetoprotein may be useful in the evaluation and follow-up of esophageal alpha-fetoprotein-producing adenocarcinoma. Copyright © 2012. Published by Elsevier B.V.

  15. Serumferritin - diagnostic relevance and clinical usefulness

    The introduction of a WHO Standard for serumferritin effected a standardisation of different methods, improving quality and security for clinical routine diagnostic purposes. Therefore the clinical evaluation of serumferritin gained even more importance. For evaluation of iron stores of children, pregnant women, population studies, patients on hemodialysis or patients with rheumatoid arthritis low serumferritin values give safe results. In addition serumferritin is of clinical usefulness in monitoring therapy of both iron deficiency and iron overload. Evaluating a single serumferritin value one should consider the total clinical situation of the patient. As some tumors can produce and secrete serumferritin, e.g. acute myeloblastic leukemia, germ cell tumors, malignant melanoma, serumferritin might be helpful in monitoring the malignant disease. The ongoing characterization of tissue isoferritin, especially acidic isoferritin, may eventually lead to a clinically significant diagnostic marker of neoplasia.

    The increasing incidence of carbapenem-resistant Pseudomonas aeruginosa along with the discovery of novel metallo-β-lactamases (MBLs) is of concern. In this study, the isolation of Malaysian MBL-producing P. aeruginosa clinical strains was investigated. Fifty-three P. aeruginosa clinical strains were isolated from different patients in Sultanah Aminah Hospital, Johor Bahru, Malaysia in 2015. Antimicrobial susceptibility test was conducted. Minimum inhibitory concentrations (MICs) of imipenem and meropenem were determined by Etest. The carbapenem-resistant strains were screened for MBL production by IMP-EDTA double disk synergy test (DDST), MBL imipenem/imipenem-inhibitor (IP/IPI) Etest and polymerase chain reaction (PCR). Genotyping was performed by multilocus sequence typing (MLST) analysis. Three (5.7%) clinical strains were identified as MBL producers. Multidrug resistance was observed in the three strains, and two were resistant to all the antimicrobials tested. Sequencing analysis confirmed the three strains to harbour carbapenemase genes: one with bla IMP-1 , one with bla VIM-2 and the other with bla NDM-1 genes. These multidrug resistant strains were identified as sequence type (ST) 235 and ST308. None of the bla IMP-1 and bla NDM-1 genes have been reported in Malaysian P. aeruginosa. The emergence of imipenemase 1 (IMP-1)- and New Delhi metallo-β-lactamase 1 (NDM-1)-producing P. aeruginosa in Malaysia maybe travel-associated. Copyright © 2018. Published by Elsevier Ltd.

    Resistance patterns and carbapenemase gene presence among Klebsiella pneumoniae isolates from the University General Hospital of Patras, Greece during a ten-year period were analysed under a surveillance programme for multi-drug-resistant bacteria. From 2005 to 2014, K. pneumoniae isolates from clinically significant specimens were identified by the Vitek 2 Advanced Expert System. Antibiotic susceptibility testing was performed by the agar disc diffusion method and Etest. The strains were tested for the presence of blaVIM, blaIMP, blaKPC, blaNDM and blaOXA-48 genes by PCR. PFGE of chromosomal Xbal DNA digests was performed. A total of 3449 K. pneumoniae isolates were recovered during the last decade. Among them, 1668 (48 %) were carbapenemase-producing: 1333 (80%) K. pneumoniae carbapenemase (KPC)-, 286 (17%) Verona imipenemase (VIM), 45 (3%) KPC- and VIM-, and four New Delhi metallo-beta-lactamase (NDM)-producing. Their resistance rates to gentamicin, colistin and tigecycline were 41%, 23% and 16%, respectively. VIM-producing K. pneumoniae were isolated in 2005 and since 2008 have been endemic. KPC-producing K. pneumoniae (KPC-Kp) isolates were introduced in 2008 and until now represent the predominant carbapenemase-producing K. pneumoniae in our institution. PFGE of 97 KPC-Kp strains identified three types: A, 84 (87%); B, 11 (11%); and E, two (2%). Eleven co-producing KPC and VIM K. pneumoniae isolates belonged to PFGE B. The four NDM-positives were classified to type F. The number of K. pneumoniae bacteraemias increased during the study period, which may be solely attributed to the increase of carbapenemase-producing isolates. The threat of carbapenemase-producing K. pneumoniae emphasizes the urgent need for implementation of infection control measures and budgetary allocations to infection control.

    Abstract Rationale, aims and objectives In the UK fewer than 15% of familial hypercholesterolemia (FH) cases are diagnosed, representing a major gap in coronary heart disease prevention. We wished to support primary care doctors within the Medway Clinical Commissioning Group (CCG) to implement NICE guidance (CG71) and consider the possibility of FH in adults who have raised total cholesterol concentrations, thereby improving the detection of people with FH. Methods Utilizing clinical decision support software (Audit+) we developed an FH Audit Tool and implemented a systematic audit of electronic medical records within GP practices, first identifying all patients diagnosed with FH or possible FH and next electronically flagging patients with a recorded total cholesterol of >7.5 mmol L−1 or LDL‐C > 4.9 mmol L−1 (in adults), for further assessment. After a 2‐year period, a nurse‐led clinic was introduced to screen more intensely for new FH index cases. We evaluated if these interventions increased the prevalence of FH closer to the expected prevalence from epidemiological studies. Results The baseline prevalence of FH within Medway CCG was 0.13% (1 in 750 persons). After 2 years, the recorded prevalence of diagnosed FH increased by 0.09% to 0.22% (1 in 450 persons). The nurse advisor programme ran for 9 months (October 2013–July 2014) and during this time, the recorded prevalence of patients diagnosed with FH increased to 0.28% (1 in 357 persons) and the prevalence of patients ‘at risk and unscreened’ reduced from 0.58% to 0.14%. Conclusions Our study shows that two simple interventions increased the detection of FH. This systematic yet simple electronic case‐finding programme with nurse‐led review allowed the identification of new index cases, more than doubling the recorded prevalence of detected disease to 1 in 357 (0.28%). This study shows that primary care has an important role in identifying patients with this condition. PMID

    Although the rapid spread of carbapenemase-producing Gram-negatives (CPGNs) is providing the scientific community with a great deal of information about the molecular epidemiology of these enzymes and their genetic background, data on how to treat multidrug-resistant or extended drug-resistant carbapenemase-producing Enterobacteriaceae and how to contain their spread are still surprisingly limited, in spite of the rapidly increasing prevalence of these organisms and of their isolation from patients suffering from life-threatening infections. Limited clinical experience and several in vitro synergy studies seem to support the view that antibiotic combinations should be preferred to monotherapies. But, in light of the data available to date, it is currently impossible to quantify the real advantage of drug combinations in the treatment of these infections. Comprehensive clinical studies of the main therapeutic options, broken down by pathogen, enzyme and clinical syndrome, are definitely lacking and, as carbapenemases keep spreading, are urgently needed. This spread is unveiling the substantial unpreparedness of European public health structures to face this worrisome emergency, although experiences from different countries-chiefly Greece and Israel-have shown that CPGN transmission and cross-infection can cause a substantial threat to the healthcare system. This unpreparedness also affects the treatment of individual patients and infection control policies, with dramatic scarcities of both therapeutic options and infection control measures. Although correct implementation of such measures is presumably cumbersome and expensive, the huge clinical and public health problems related to CPGN transmission, alongside the current scarcity of therapeutic options, seem to fully justify this choice.

    The cytoskeleton, and in particular its microtubule component, participates in several processes that directly affect growth and development in higher plants. Normal cytoskeletal function requires the precise and orderly arrangement of microtubules into several cell cycle and developmentally specific arrays. One of these, the cortical array, is notable for its role in directing the deposition of cellulose (the most prominent polymer in the biosphere). An understanding of how these arrays form, and the molecular interactions that contribute to their function, is incomplete. To gain a better understanding of how microtubules work, we have been working to characterize mutants in critical cytoskeletal genes. This characterization is being carried out at the subcellular level using vital microtubule gene constructs. In the last year of funding colleagues have discovered that gamma-tubulin complexes form along the lengths of cortical microtubules where they act to spawn new microtubules at a characteristic 40 deg angle. This finding complements nicely the finding from our lab (which was funded by the DOE) showing that microtubule encounters are angle dependent; high angles encounters results in catastrophic collisions while low angle encounters result in favorable zippering. The finding of a 40 deg spawn of new microtubules from extant microtubule, together with aforementioned rules of encounters, insures favorable co-alignment in the array. I was invited to write a New and Views essay on this topic and a PDF is attached (News and Views policy does not permit funding acknowledgments and so I was not allowed to acknowledge support from the DOE).

    Treatment of infections caused by carbapenemase-producing Enterobacteriaceae (CPE) is currently one of the most important challenges of infectious diseases. The available information is based on in vitro studies, some animal model data and a few case studies and retrospective cohorts; appropriate data are lacking or are very scarce for some old antibiotics that are still occasionally used. Because of the heterogeneity in clinical situations, in specific carbapenemases and in the susceptibility of isolates, individualized treatment decisions must usually be made. Here we review the different antibiotics that might be useful for treating infections caused by CPE. Copyright © 2014 Elsevier España, S.L.U. All rights reserved.

    The aims of this paper were to explicate clinical scholarship as synonymous with the scholarship of application and to explore the evolution of scholarly practice to clinical scholarship. Boyer contributed an expanded view of scholarship that recognized various approaches to knowledge production beyond pure research (discovery) to include the scholarship of integration, application and teaching. There is growing interest in using Boyer's framework to advance knowledge production in nursing but the discussion of clinical scholarship in relation to Boyer's framework is sparse. Discussion paper. Literature from 1983-2015 and Boyer's framework. When clinical scholarship is viewed as a synonym for Boyer's scholarship of application, it can be aligned to this well established framework to support knowledge generated in clinical practice. For instance, applying the three criteria for scholarship (documentation, peer review and dissemination) can ensure that the knowledge produced is rigorous, available for critique and used by others to advance nursing practice and patient care. Understanding the differences between scholarly practice and clinical scholarship can promote the development of clinical scholarship. Supporting clinical leaders to identify issues confronting nursing practice can enable scholarly practice to be transformed into clinical scholarship. Expanding the understanding of clinical scholarship and linking it to Boyer's scholarship of application can assist nurses to generate knowledge that addresses clinical concerns. Further dialogue about how clinical scholarship can address the theory-practice gap and how publication of clinical scholarship could be expanded given the goals of clinical scholarship is warranted. © 2016 John Wiley & Sons Ltd.

    Carbapenems are the last line of defence against ever more prevalent MDR Gram-negative bacteria, but their efficacy is threatened worldwide by bacteria that produce carbapenemase enzymes. The epidemiology of bacteria producing carbapenemases has been described in considerable detail in Europe, North America and Asia; however, little is known about their spread and clinical relevance in Africa. We systematically searched in PubMed, EBSCOhost, Web of Science, Scopus, Elsevier Masson Consulte and African Journals Online, international conference proceedings, published theses and dissertations for studies reporting on carbapenemase-producing bacteria in Africa. We included articles published in English or French up to 28 February 2014. We calculated the prevalence of carbapenemase producers only including studies where the total number of isolates tested was at least 30. Eighty-three studies were included and analysed. Most studies were conducted in North Africa (74%, 61/83), followed by Southern Africa (12%, 10/83), especially South Africa (90%, 9/10), West Africa (8%, 7/83) and East Africa (6%, 6/83). Carbapenemase-producing bacteria were isolated from humans, the hospital environment and community environmental water samples, but not from animals. The prevalence of carbapenemase-producing isolates in hospital settings ranged from 2.3% to 67.7% in North Africa and from 9% to 60% in sub-Saharan Africa. Carbapenemase-producing bacteria have been described in many African countries; however, their prevalence is poorly defined and has not been systematically studied. Antibiotic stewardship and surveillance systems, including molecular detection and genotyping of resistant isolates, should be implemented to monitor and reduce the spread of carbapenemase-producing bacteria. © The Author 2014.

    The UK National Institute for Health and Clinical Excellence (NICE) guidance recommends conservative management of men with 'low-risk' localised prostate cancer, monitoring the disease using prostate-specific antigen (PSA) kinetics and re-biopsy. However, there is little evidence of the changes in PSA level that should alert to the need for clinical re-assessment. This study compares the alerts resulting from PSA kinetics and a novel longitudinal reference range approach, which incorporates age-related changes, during the monitoring of 408 men with localised prostate cancer. Men were monitored by regular PSA tests over a mean of 2.9 years, recording when a man's PSA doubling time fell below 2 years, PSA velocity exceeded 2 ng ml(-1) per year, or when his upper 10% reference range was exceeded. Prostate-specific antigen doubling time and PSA velocity alerted a high proportion of men initially but became unresponsive to changes with successive tests. Calculating doubling time using recent PSA measurements reduced the decline in response. The reference range method maintained responsiveness to changes in PSA level throughout the monitoring. The increasing unresponsiveness of PSA kinetics is a consequence of the underlying regression model. Novel methods are needed for evaluation in cohorts currently being managed by monitoring. Meanwhile, the NICE guidance should be cautious.

    The use of tamoxifen and raloxifene as preventive therapy for women at increased risk of breast cancer was approved by the National Institute for Health and Care Excellence (NICE) in 2013. We undertook a qualitative investigation to investigate the factors affecting the implementation of preventive therapy within the UK. We recruited general practitioners (GPs) (n = 10) and clinicians working in family history or clinical genetics settings (FHCG clinicians) (n = 15) to participate in semi-structured interviews. Data were coded thematically within the Consolidated Framework for Implementation Research. FHCG clinicians focussed on the perceived lack of benefit of preventive therapy and difficulties interpreting the NICE guidelines. FHCG clinicians felt poorly informed about preventive therapy, and this discouraged patient discussions on the topic. GPs were unfamiliar with the concept of preventive therapy, and were not aware that they may be asked to prescribe it for high-risk women. GPs were reluctant to initiate therapy because it is not licensed, but were willing to continue a prescription if it had been started in secondary or tertiary care.

  11. Should fertility clinics divest themselves of pornography?

    OpenAIRE

    Murphy, Timothy F

    2016-01-01

    Some commentators object to the way in which fertility clinics make pornography available to men as an aid to masturbation when those men produce sperm for evaluation, storage or IVF. These objections typically rely on claims that pornography is generally harmful to women, unnecessary and dissociates sexual acts from conception. In light of these objections, certain commentators want fertility clinics to divest themselves of pornography, but these objections to pornography are not morally con...

    Guidelines for investigation of perioperative drug allergy exist, but the quality of services is unknown. Specialist perioperative anaphylaxis services were surveyed through the Royal College of Anaesthetists 6 th National Audit Project. We compare self-declared UK practice in specialist perioperative allergy services with national recommendations. A SurveyMonkey™ questionnaire was distributed to providers of allergy services in the UK. Responses were assessed for adherence to the best practice recommendations of the British Society for Allergy and Clinical Immunology (BSACI), the Association of Anaesthetists of Great Britain and Ireland and the National Institute for Health and Care Excellence (NICE) Guidance on Drug Allergy-CG183. Over 1200 patients were evaluated in 44 centres annually. Variation in workload, waiting times, access, staffing and diagnostic approach was noted. Paediatric centres had the longest routine waiting times (most wait >13 weeks) in contrast to adult centres (most wait specialist nurses and 18/44 (41%) an anaesthetist] and provision of information [18/44 (41%) gave immediate information in clinic and 5/44 (11%) sign-posted support groups]. Most centres were able to provide diagnostic challenges to antibiotics [40/44 (91%]) and local anaesthetics [41/44 (93%)]. Diagnostic testing is not harmonized, with marked variability in the NMBA panels used to identify safe alternatives. Chlorhexidine and latex are not part of routine testing in many centres. Poor access to services and patient information provision require attention. Harmonization of diagnostic approach is desirable, particularly with regard to a minimum NMBA panel for identification of safe alternatives. © 2017 John Wiley & Sons Ltd.

    The prevalence of carbapenemase-producing Enterobacteriaceae (CPE) has been increasing worldwide. blaIMP has been reported to be the predominant carbapenemase-encoding gene within Enterobacteriaceae in Australia. However, there are limited data currently available on CPE from Queensland, Australia. A total of 58 CPE isolates were isolated between July 2009 and March 2014 from Queensland hospitals. The clonality of isolates was determined by Diversilab repetitive sequence-based PCR. The isolates were investigated for the resistance mechanisms carbapenemase, extended-spectrum β-lactamase, and AmpC β-lactamase and for aminoglycoside resistance and plasmid-mediated quinolone resistance genes by PCR. The plasmid types associated with carbapenemase-encoding genes were characterized. The majority of the CPE were Enterobacter cloacae (n = 29). The majority of Queensland CPE isolates were IMP producers and comprised 11 species (n = 48). Nine NDM-producing Enterobacteriaceae were identified. One NDM-producing Klebsiella pneumoniae isolate coproduced OXA-48. One K. pneumoniae isolate was an OXA-181 producer. The incidence of IMP producers increased significantly in 2013. blaIMP-4 was found in all IMP-producing isolates. blaTEM, qnrB, and aacA4 were common among IMP-4 producers. The HI2 (67%) and L/M (21%) replicons were associated with blaIMP-4. All HI2 plasmids were of sequence type 1 (ST1). All but one of the NDM producers possessed blaCTX-M-15. The 16S rRNA methylase genes found among NDM producers were armA, rmtB, rmtC, and rmtF. The substantial increase in the prevalence of CPE in Queensland has been associated mainly with the emergence E. cloacae strains possessing HI2 plasmids carrying blaIMP-4 over the past 2 years. The importation of NDM producers and/or OXA-48-like producers in patients also contributed to the increased emergence of CPE. PMID:25918153

    The emergence of carbapenemase-producing Enterobacteriaceae (CPE) represents a major clinical problem because these bacteria are resistant to most antibiotics. CPE remain relatively uncommon in Korea. We report the prevalence, clinical characteristics, and molecular epidemiology of CPE isolates collected from five university hospitals in Korea. Between January and December 2015, 393 non-duplicated isolates that were nonsusceptible to ertapenem were analyzed. Production of carbapenemase, extended-spectrum β-lactamase, and AmpC β-lactamase was determined by genotypic tests. Antimicrobial susceptibility profiles were determined by using an Etest. Clonality of Klebsiella pneumoniae carbapenemase (KPC)-2-producing and oxacillinase (OXA)-232-producing Klebsiella pneumoniae isolates was determined by pulsed-field gel electrophoresis (PFGE). Of the 393 isolates tested, 79 (20.1%) were CPE. Of these 79 isolates, 47 (59.5%) harbored the bla(OXA-232) gene while the remaining isolates carried genes bla(KPC-2) (n=27), bla(IMP-1) (n=4), and bla(NDM-1) (n=1). Among the 24 KPC-2 K. pneumoniae isolates from hospital B, 100% were resistant to carbapenems, 8% to colistin, and 0% to tigecycline. Among the 45 OXA-232 K. pneumoniae at hospital C, 95% were resistant to ertapenem, 68% to imipenem, 95% to meropenem, 10% to colistin, and 24% to tigecycline. PFGE analysis revealed a unique pattern for KPC-2 K. pneumoniae and identified 30 isolates belonging to the dominant pulsotypes (PT)1 and PT2 among 41 OXA-232 K. pneumoniae isolates. CPE strains are present in Korea, with the majority of K. pneumoniae isolates producing OXA-232 and KPC-2. The prevalence and predominant genotypes of CPE show hospital-specific differences.

    2012-07-01

    To compare the types of benefit considered relevant by the English Department of Health with those included by the National Institute for Health and Clinical Excellence (NICE) when conducting economic evaluations of options for spending limited health care resources. We analysed all policy Impact Assessments (IAs) carried out by the Department of Health (DH) in 2008 and 2009. The stated benefits of each policy were extracted and thematic analysis was used to categorise these. 51 Impact Assessments were analysed, eight of which mentioned quality-adjusted life year (QALY) gains as a benefit. 18 benefits other than QALY gains were identified. Apart from improving health outcomes, commonly referred to benefits included: reducing costs, improving quality of care, and enhancing patient experience. Many of the policies reviewed were implemented on the basis of benefits unrelated to health outcome. The methods being used to apply a monetary valuation to QALY gains (in cost-benefit calculations) are not consistent across Impact Assessments or with NICE's stated threshold range. The Department of Health and NICE approach resource allocation decisions in different ways, based upon overlapping but not congruent considerations and underlying principles. Given that all these decisions affect the allocation of the same fixed health care budget, there is a case for establishing a uniform framework for option appraisal and priority setting so as to avoid allocative inefficiency. The same applies to any other national health care system.

  17. A study of the relationship between albuminuria, proteinuria and urinary reagent strips.

    LENUS (Irish Health Repository)

    Collier, Geraldine

    2012-02-01

    BACKGROUND: The aims of this study were to examine the relationship between proteinuria and albuminuria and to assess the equivalence between the albumin to creatinine ratio (ACR) and the protein to creatinine ratio (PCR) at the cut-offs recommended by the National Institute for Health and Clinical Excellence (NICE) guidance on chronic kidney disease. The sensitivity and specificity of the reagent strips used in our laboratory for the detection of clinical proteinuria was also assessed. METHODS: Urine samples (n = 117) were screened for protein using the Bayer Multistix 10SG and read manually. Urinary total protein and creatinine was measured on the Roche P Modular by the benzethonium chloride and kinetic Jaffe methods, respectively. Urinary albumin was measured by immunoturbidimetry on the Roche Cobas Mira. RESULTS: The relationship between urinary protein and albumin loss was non-linear (P < 0.05). As urinary protein loss increased the percentage of albumin to total protein increased. At the NICE guidance recommended cut-offs for clinical proteinuria (ACR > or =30 mg\\/mmol and PCR > or =50 mg\\/mmol) there was one discordant result between ACR and PCR (ACR <30 mg\\/mmol and PCR >50 mg\\/mmol). The Bayer Multistix 10SG had a sensitivity and specificity of 97% and 62%, respectively, for the detection of clinical proteinuria compared with ACR. CONCLUSIONS: The proportion of urinary total protein attributable to albumin changes with concentration. There was only one discordant result between ACR and PCR: therefore either ratio may be used for the identification of clinical proteinuria. As a screening test for proteinuria, the Bayer Multistix 10SG had an acceptable sensitivity but poor specificity.

    Experimental works to use wood wastes for producing charcoal are examined, which are being conducted in the Sverdlovsk assembly and adjustment administration of Soyuzorglestekhmontazh. A wasteless prototype installation for producing fine charcoal is described, along with its subsequent briqueting, which is made on the basis of units which are series produced by the factories of the country. The installation includes subassemblies for preparing and drying the raw material and for producing the charcoal briquets. In the opinion of specialists, the charcoal produced from the wastes may be effectively used in ferrous and nonferrous metallurgy and in the production of pipes.

    Full Text Available Introduction: Biofilm production is an important mechanism for the survival of Pseudomonas aeruginosa and its relationship with antimicrobial resistance represents a challenge for patient therapeutics. P. aeruginosa is an opportunistic pathogen frequently associated to nosocomial infections, especially in imunocompromised hosts. Objectives: Analyze the phenotypic biofilm production in P. aeruginosa isolates, describe clonal profiles, and analyze quorum sensing (QS genes and the occurrence of mutations in the LasR protein of non-biofilm producing isolates. Methods: Isolates were tested for biofilm production by measuring cells adherence to the microtiter plates. Clonal profile analysis was carried out through ERIC-PCR, QS genes were by specific PCR. Results: The results showed that 77.5% of the isolates were considered biofilm producers. The results of genotyping showed 38 distinct genetic profiles. As for the occurrence of the genes, 100% of the isolates presented the lasR, rhlI and rhlR genes, and 97.5%, presented the lasI gene. In this study nine isolates were not biofilm producers. However, all presented the QS genes. Amplicons related to genes were sequenced in three of the nine non-biofilm-producing isolates (all presenting different genetic similarity profile and aligned to the sequences of those genes in P. aeruginosa strain PAO1 (standard biofilm-producing strain. Alignment analysis showed an insertion of three nucleotides (T, C and G causing the addition of an amino acid valine in the sequence of the LasR protein, in position 53. Conclusion: The modeling of the resulting LasR protein showed a conformational change in its structure, suggesting that this might be the reason why these isolates are unable to produce biofilm.

    Full Text Available In a world experiencing profound technological and socio-political changes in areas of knowledge and capacity, healthcare can not remain static. A new kind of professional is required, whose practice is based on ethics, scientific standards, integrity, citizenship, and health promotion, who develops skills beyond healthcare, such as decision making, communication,leadership, management, and continuing education. No single method can assess all of these elements (knowledge, skills, and attitudes, and only a combination of methods is able to produce a valid evaluation. An alternative method exists: structured clinical assessments based on observation of "to do, or how to do" that aim to complete this evaluation by focusing attention on the performance of specific skills. In order to broaden the scope of evaluation methods that have been used in health education, this article, a literature review, intends to offer readers an overview of the diverse types of structured clinical evaluation, emphasizing Objective Structured Clinical Examination, the most widely used in Brazil, with a goal of advancing opportunities for health professionals to make use of this evaluative tool.

    2009-01-01

    Currently small electronic devices capable of producing high quality images are available. The massive use of these devices has become common in the clinical setting as medical images represent a useful tool to document relevant clinical conditions for patient diagnosis, treatment and follow-up. Besides, clinical images are beneficial for legal, scientific and academic purposes. The extended practice without proper ethical guidelines might represent a significant risk for the protection of patient rights and clinical practice. This document discusses risks and duties when obtaining medical images, and presents some arguments on institutional and professional responsibilities around the definition of policies regarding the protection of privacy and dignity of the patient.

    We evaluated the combined use of the modified Hodge test (MHT) and carbapenemase inhibition test (CIT) using phenylboronic acid (PBA) and EDTA to detect carbapenemase-producing Enterobacteriaceae (CPE) and metallo-β-lactamase (MBL)-producing Pseudomonas spp. A total of 49 isolates of CPE (15 Klebsiella pneumoniae carbapenemase [KPC], 5 Guiana extended-spectrum β-lactamase [GES]-5, 9 New Delhi metallo-β-lactamase [NDM]-1, 5 Verona integron-encoded metallo-β-lactamase [VIM]-2, 3 imipenem-hydrolyzing β-lactamase [IMP], and 12 oxacillinase [OXA]-48-like), 25 isolates of MBL-producing Pseudomonas spp. (14 VIM-2 and 11 IMP), and 35 carbapenemase-negative controls were included. The MHT was performed for all isolates as recommended by the Clinical and Laboratory Standards Institute. Enhanced growth of the indicator strain was measured in mm with a ruler. The CIT was performed by directly dripping PBA and EDTA solutions onto carbapenem disks that were placed on Mueller-Hinton agar plates seeded with the test strain. Considering the results of the MHT with the ertapenem disk in Enterobacteriaceae and Pseudomonas spp., the CIT with the meropenem disk in Enterobacteriaceae, and the imipenem disk in Pseudomonas spp., three combined disk tests, namely MHT-positive plus PBA-positive, EDTA-positive, and MHT-positive plus PBA-negative plus EDTA-negative, had excellent sensitivity and specificity for the detection of KPC- (100% sensitivity and 100% specificity), MBL- (94% sensitivity and 100% specificity), and OXA-48-like-producing isolates (100% sensitivity and 100% specificity), respectively. Combined use of the MHT and CIT with PBA and EDTA, for the detection of CPE and MBL-producing Pseudomonas spp., is effective in detecting and characterizing carbapenemases in routine laboratories.

    Although carbapenem is the recommended for urinary tract infection (UTI) caused by extended-spectrum beta-lactamase (ESBL)-producing organisms, non-carbapenems have been reported to be effective for adult patients with UTI caused by ESBL-producing organisms. The purpose of this study was to evaluate the efficacy of non-carbapenems for pediatric patients with UTI due to ESBL-producing Escherichia coli (E. coli) based on the microbiologic and clinical outcomes. Fifteen children, who were treated for first febrile UTI caused by ESBL-producing E. coli were enrolled in this study. Antimicrobial susceptibilities and ESBL production were determined according to the Clinical and Laboratory Standards Institute guidelines. To detect CTX-M genes, polymerase chain reaction was performed with specific primers for bla CTX-M detection. Of the 15 enrolled patients, 10 (66.7%) were boys and 5 (33.3%) were girls, with a median age of four months. VUR was detected in six patients (40%). For detection of bla CTX-M by PCR, CTX-M-3, CTX-M-8, CTX-M-14, and CTX-M-15 were detected in five, one, eight, and one patient, respectively. Overall, 14 of the 15 isolates (93.3%) were susceptible for fosfomycin (FOM), and all isolates were susceptible for cefmetazole (CMZ), flomoxef (FMOX), and imipenem/cilastatin (IPM/CS). Of the 15 patients, 12 (80%) clinically improved without the use of carbapenems. In conclusion, even if isolates of ESBL-producing E. coli are multidrug resistant based on MIC assessment, clinical susceptibility to non-carbapenems, such as CMZ, FMOX, and FOM, is possible. Accordingly, carbapenems may not be required all the time for treatment of pediatric UTI in clinical practice.

    1989-01-01

    This project supports the conversion of codes in Computational Structural Mechanics (CSM) to a parallel form which will efficiently exploit the computational power available from multiprocessors. The work is a part of a comprehensive, FORTRAN-based system to form a basis for a parallel version of the NICE/SPAR combination which will form the CSM Testbed. The software is macro-based and rests on the force methodology developed by the principal investigator in connection with an early scientific multiprocessor. Machine independence is an important characteristic of the system so that retargeting it to the Flex/32, or any other multiprocessor on which NICE/SPAR might be imnplemented, is well supported. The principal investigator has experience in producing parallel software for both full and sparse systems of linear equations using the force macros. Other researchers have used the Force in finite element programs. It has been possible to rapidly develop software which performs at maximum efficiency on a multiprocessor. The inherent machine independence of the system also means that the parallelization will not be limited to a specific multiprocessor.

    Fibroblast growth factor (FGF) 18 has been shown to increase cartilage volume when injected intra-articularly in animal models of osteoarthritis (OA) and in patients with knee OA (during clinical development of the recombinant human FGF18, sprifermin). However, the exact nature of this effect is still unknown. In this study, we aimed to investigate the effects of sprifermin at the cellular level. A combination of different chondrocyte culture systems was used and the effects of sprifermin on proliferation, the phenotype and matrix production were evaluated. The involvement of MAPKs in sprifermin signalling was also studied. In monolayer, we observed that sprifermin promoted a round cell morphology and stimulated both cellular proliferation and Sox9 expression while strongly decreasing type I collagen expression. In 3D culture, sprifermin increased the number of matrix-producing chondrocytes, improved the type II:I collagen ratio and enabled human OA chondrocytes to produce a hyaline extracellular matrix (ECM). Furthermore, we found that sprifermin displayed a 'hit and run' mode of action, with intermittent exposure required for the compound to fully exert its anabolic effect. Finally, sprifermin appeared to signal through activation of ERK. Our results indicate that intermittent exposure to sprifermin leads to expansion of hyaline cartilage-producing chondrocytes. These in vitro findings are consistent with the increased cartilage volume observed in the knees of OA patients after intra-articular injection with sprifermin in clinical studies.

    In this brief communication we describe the occurrence of a KPC-producing Serratia marcescens isolate in a home-care patient from Recife, Brazil. The blaKPC, blaSPM, blaIMP, blaVIM, blaOXA, blaCTX-M, blaSHV, blaTEM and blaGES genes were investigated by Polymerase Chain Reaction (PCR) and DNA sequencing. The isolate was positive for blaKPC-2 and blaTEM-1 and was resistant to aztreonam, cefepime, cefotaxime, imipenem, meropenem, gentamicin, ciprofloxacin and cefazidime, and susceptible only to amikacin, tigecycline and gatifloxacin. This is the first report in Brazil of KPC-producing S. marcescens clinical isolate outside of a hospital environment. Caregivers should be alert for the presence of this isolate in the community setting.

    Sperm competition theory can be used to generate the hypothesis that men alter the quality of their ejaculates as a function of sperm competition risk. Using a repeated measures experimental design, we investigated whether men produce a higher quality ejaculate when primed with cues to sperm competition (i.e., imagined partner infidelity) relative to a control prime. Men ( n = 45) submitted two masturbatory ejaculates-one ejaculate sample for each condition (i.e., sperm competition and control conditions). Ejaculates were assessed on 17 clinical parameters. The results did not support the hypothesis: Men did not produce higher quality ejaculates in the sperm competition condition relative to the control condition. Despite the null results of the current research, there is evidence for psychological and physiological adaptations to sperm competition in humans. We discuss methodological limitations that may have produced the null results and present methodological suggestions for research on human sperm competition.

    The 19th and 20th centuries witnessed the growth and development of clinical chemistry. Many of the individuals and the significance of their contributions are not very well known, especially to new members of the profession. This survey should help familiarize them with the names and significance of the contributions of physicians and chemists such as Fourcroy, Berzelius, Liebig, Prout, Bright, and Rees. Folin and Van Slyke are better known, and it was their work near the end of the second decade of the 20th century that brought the clinical chemist out of the annex of the mortuary and into close relationship with the patient at the bedside. However, the impact on clinical chemistry and the practice of medicine by the 1910 exposé written by Abraham Flexner is not as well known as it deserves to be, nor is the impetus that World War I gave to the spread of laboratory medicine generally known. In the closing decades of the 20th century, automated devices produced an overabundance, and an overuse and misuse, of testing to the detriment of careful history taking and bedside examination of the patient. This is attributable in part to a fascination with machine-produced data. There was also an increased awareness of the value of chemical methods of diagnosis and the need to bring clinician and clinical chemist into a closer partnership. Clinical chemists were urged to develop services into dynamic descriptions of the diagnostic values of laboratory results and to identify medical relevance in interpreting significance for the clinician.

    Five OXA-48-producing Klebsiella pneumoniae were detected in a tertiary referral hospital in Ireland between March and June 2011. They were found in the clinical isolates of five cases that were inpatients on general surgical wards. None of the cases had received healthcare at a facility outside of Ireland in the previous 12 months. This is the first report of OXA-48-producing K. pneumoniae in Ireland.

    A mixture of power producing coals with coal briquets of varying composition is proposed for coking in horizontal chamber furnaces. The briquets are produced from petroleum coke, coal fines or semicoke, which make up less than 27 percent of the mixture to be briquetted and coals with a standard coking output of volatile substances and coals with high maximal Gizeler fluidity. The ratio of these coals in the mixture is 0.6 to 2.1 or 18 to 32 percent, respectively. Noncaking or poorly caking coals are used as the power producing coals. The hardness of the obtained coke is DJ15-30 = 90.5 to 92.7 percent.

    Urinary tract infection (UTI) caused by resistant strains of bacteria is increasingly prevalent in children. The aim of this study was to investigate the clinical characteristics and risk factors for UTI caused by community-acquired extended-spectrum β-lactamase (CA-ESBL)-producing bacteria in infants. This was a retrospective study performed over 5 years in a single Korean center. Hospitalized infants with febrile UTI were enrolled and divided into two groups (CA-ESBL vs. CA non-ESBL UTI). The yearly prevalence was calculated. Baseline characteristics and clinical course such as fever duration, laboratory and radiological findings were compared between the two groups. Risk factors associated with the CA-ESBL UTI were investigated. Among the enrolled infants (n=185), 31 (17%) had CA-ESBL UTI. The yearly prevalence of ESBL of CA-ESBL UTI increased during the study (0% in 2010, 22.2% in 2015). Infants with CA-ESBL UTI had a longer duration of fever after initiating antibiotics (2.0±1.1 vs. 1.5±0.6 days, p=0.020). Cortical defects on renal scan and early treatment failure were more frequent in CA-ESBL (64.5 vs. 42.2%, p=0.023; 22.6 vs. 4.5%, p=0.001). A logistic regression analysis revealed that urinary tract abnormalities and previous UTI were independent risk factors for CA-EBSL UTI (odds ratio, 2.7; p=0.025; 10.3; p=0.022). The incidence of UTI caused by ESBL-producing bacteria has increased in Korean infants. Recognition of the clinical course and risk factors for ESLB-producing UTI may help to determine appropriate guidelines for its management. Copyright © 2016. Published by Elsevier Editora Ltda.

    To assess the impact of referral refinement criteria on the number of patients referred to, and first-visit discharges from, the Hospital Eye Service (HES) in relation to the National Institute for Health & Clinical Excellence (NICE) Glaucoma Guidelines, Joint College Group Guidance (JCG) and the NICE commissioning guidance. All low-risk (one risk factor: suspicious optic disc, abnormal visual field (VF), raised intra-ocular pressure (IOP) (22-28 mmHg) or IOP asymmetry (>5 mmHg) and high-risk (more than one risk factor, shallow anterior chamber or IOP >28 mmHg) referrals to the HES from 2006 to 2011 were analysed. Low-risk referrals were seen by Optometrists with a specialist interest in glaucoma and high-risk referrals were referred directly to the HES. Two thousand nine hundred and twelve patient records were analysed. The highest Consultant first-visit discharge rates were for referrals based on IOP alone (45% for IOP 22-28 mmHg) and IOP asymmetry (53%), VF defect alone (46%) and for abnormal IOP and VF (54%). The lowest first-visit discharge rates were for referrals for suspicious optic disc (19%) and IOP >28 mmHg (22%). 73% of patients aged 65-80 and 60% of patients aged >80 who were referred by the OSI due to an IOP between 22-28 mmHg would have satisfied the JCG criteria for non-referral. For patients referred with an IOP >28 mmHg and an otherwise normal examination, adherence to the NICE commissioning guidance would have resulted in 6% fewer referrals. In 2010 this scheme reduced the number of patients attending the HES by 15%, which resulted in a saving of £16 258 (13%). The results support that referrals for a raised IOP alone or in combination with an abnormal VF be classified as low-risk and undergo referral refinement. Adherence to the JCG and the NICE commissioning guidance as onward referral criteria for specialist optometrists in this referral refinement scheme would result in fewer referrals.

    Antibiotic prophylaxis given before invasive dental procedures in patients at risk of developing infective endocarditis has historically been the focus of infective endocarditis prevention. Recent changes in antibiotic prophylaxis guidelines in the USA and Europe have substantially reduced the number of patients for whom antibiotic prophylaxis is recommended. In the UK, guidelines from the National Institute for Health and Clinical Excellence (NICE) recommended complete cessation of antibiotic prophylaxis for prevention of infective endocarditis in March, 2008. We aimed to investigate changes in the prescribing of antibiotic prophylaxis and the incidence of infective endocarditis since the introduction of these guidelines. We did a retrospective secular trend study, analysed as an interrupted time series, to investigate the effect of antibiotic prophylaxis versus no prophylaxis on the incidence of infective endocarditis in England. We analysed data for the prescription of antibiotic prophylaxis from Jan 1, 2004, to March 31, 2013, and hospital discharge episode statistics for patients with a primary diagnosis of infective endocarditis from Jan 1, 2000, to March 31, 2013. We compared the incidence of infective endocarditis before and after the introduction of the NICE guidelines using segmented regression analysis of the interrupted time series. Prescriptions of antibiotic prophylaxis for the prevention of infective endocarditis fell substantially after introduction of the NICE guidance (mean 10,900 prescriptions per month [Jan 1, 2004, to March 31, 2008] vs 2236 prescriptions per month [April 1, 2008, to March 31, 2013], pinfective endocarditis increased significantly above the projected historical trend, by 0·11 cases per 10 million people per month (95% CI 0·05-0·16, pinfective endocarditis was significant for both individuals at high risk of infective endocarditis and those at lower risk. Although our data do not establish a causal association, prescriptions

    Alpha-fetoprotein (AFP)-producing esophageal adenocarcinoma (EAC) is a rare occurrence. Elevation of serum AFP is commonly associated with hepatocellular carcinoma and yolk sac tumors, but rarely with esophageal carcinoma. Here, we report a rare case of AFP-producing EAC. A 51-year-old man presented with two weeks of acid reflux and a 35-lb weight loss. Laboratory data were notable for transaminitis and AFP was 2524 ng/mL. Computed tomography of the abdomen revealed abnormal thickening of the esophagus and multiple metastatic masses throughout the liver. Biopsy of one of the masses revealed adenocarcinoma of gastrointestinal origin. Subsequent upper endoscopy revealed an esophageal mass with biopsy notable for ulcerated dysplastic glandular mucosa with likely underlying malignancy. The patient underwent palliative esophageal stent placement but died two months later. Elevated AFP levels are an unusual occurrence in EAC. Prognosis is poor given its advanced presenting stage and high metastatic potential. Most cases are unsuccessfully treated with surgery and chemotherapy. Serial measurement of serum AFP may be useful for monitoring clinical status and treatment response. Clinicians should consider AFP-producing EAC in their differential diagnosis in the work-up of a liver mass in the setting of elevated AFP or liver function impairment, especially in the absence of chronic liver disease.

    Full Text Available Arterial dissections are a common cause of stroke in the young (mean age 44 to 46 years. Primary lesion is a tear of the arterial intima, which promotes platelet aggregation, thrombus formation, which further produced vessel stenosis / occlusion, distal embolism or vessel wall rupture. Vertebral artery (VA dissection appear most commonly in extracranial segments V2 and V3, and could be spontaneous (with underlying predispositions or triggered by various traumatisms. Clinicaly, VA dissection produces an ischemic stroke or transient ischemic attack , preceded by local symptoms such as neck pain or headache. The diagnosis is confirmed by neurovascular imaging. Treatment of symptomatic VA dissections respect indications of treatment in ischemic strokes. Prognosis is mostly favorable in extracranial dissections. We present the case of a left VA dissection in V2 segment, produced by physical effort (swimming, which causes 2 ischemic lesions, one in the territory of the left posterior cerebral artery and the other in the territory of the left posterolateral chorroidal artery. Patient’s treatment included antiplatelet agents, statines, and an adapted physical rehabilitation program. At three months he showed significant clinical improvement with regain of autonomy and partial recanalisation at angio-MRI of the V2 segment of the dissected artery.

    2014-04-01

    Full Text Available Animals represent potential reservoirs for the dissemination of antimicrobial resistance. Twenty domestically produced chicken meat samples were collected from 19 retail outlets in Ireland, inoculated into Bolton broth and cultured on modified charcoal cefoperazone deoxycholate (mCCDA and Preston agars. Selected representative coliforms included 16 E.coli and 4 Pseudomonas aeruginosa. All E.coli isolates were confirmed as ESBL producers, 15 isolates harbored a blaCTX-M group-1 gene, and none belonged to the E.coli 025b:H4-ST131 clonal group. Pulsed field gel electrophoresis (PFGE analysis identified 13 distinct pulsed field profiles and comparison with more than 300 human clinical isolates of ESBL producing E. coli did not reveal any similarities. ESBL producing E. coli were detected on retail meats in the Irish market place. Although no similarity was apparent between poultry and human isolates this does not preclude a role for ESBL-producing E.coli in meat in dissemination of antimicrobial resistance.

    2016-11-01

    This paper describes the development and practice of clinical neuropsychology in Australia. Clinical Neuropsychology has shown rapid growth in Australia over the past three decades. Comprehensive and specialized training programs are producing high quality graduates who are employed in a broad range of settings or private practice. Australia now has a substantial number of clinical neuropsychologists with specialist training. Whilst the majority of Australian clinical neuropsychologists still undertake assessment predominantly, there are growing opportunities for clinical neuropsychologists in rehabilitation and in a broad range of research contexts. Cultural issues relating to the assessment of Indigenous Australians and immigrants from many countries present significant challenges. Some major contributions have been made in the realms of test development and validation across various age groups. Australian clinical neuropsychologists are also contributing significantly to research in the fields of traumatic brain injury, aging and dementias, epilepsy, memory assessment, rehabilitation, substance abuse, and other psychiatric disorders. Expansion of roles of clinical neuropsychologists, in domains such as rehabilitation and research is seen as essential to underpin continuing growth of employment opportunities for the profession.

    International data on the molecular epidemiology of Enterobacteriaceae with IMP carbapenemases are lacking. We performed short-read (Illumina) whole-genome sequencing on a global collection of 38 IMP-producing clinical Enterobacteriaceae (2008 to 2014). IMP-producing Enterobacteriaceae (7 varieties within 11 class 1 integrons) were mainly present in the South Pacific and Asia. Specific bla IMP -containing integrons (In809 with bla IMP-4 , In722 with bla IMP-6 , and In687 with bla IMP-14 ) were circulating among different bacteria in countries such as Australia, Japan, and Thailand. In1312 with bla IMP-1 was present in Klebsiella pneumoniae from Japan and Citrobacter freundii from Brazil. Klebsiella pneumoniae ( n = 22) was the most common species; clonal complex 14 (CC14) from Philippines and Japan was the most common clone and contained In1310 with bla IMP-26 and In1321 with bla IMP-6 The Enterobacter cloacae complex ( n = 9) consisted of Enterobacter hormaechei and E. cloacae cluster III. CC78 (from Taiwan) containing In73 with bla IMP-8 was the most common clone among the E. cloacae complex. This study highlights the importance of surveillance programs using the latest molecular techniques for providing insight into the characteristics and global distribution of Enterobacteriaceae with bla IMP genes.

    A comprehensive knowledge of mitral valve (MV) anatomy is crucial in the assessment of MV disease. While the use of three-dimensional (3D) modelling and printing in MV assessment has undergone early clinical evaluation, the precision and usefulness of this technology requires further investigation. This study aimed to assess and validate 3D modelling and printing technology to produce patient-specific 3D MV models. A prototype method for MV 3D modelling and printing was developed from computed tomography (CT) scans of a plastinated human heart. Mitral valve models were printed using four 3D printing methods and validated to assess precision. Cardiac CT and 3D echocardiography imaging data of four MV disease patients was used to produce patient-specific 3D printed models, and 40 cardiac health professionals (CHPs) were surveyed on the perceived value and potential uses of 3D models in a clinical setting. The prototype method demonstrated submillimetre precision for all four 3D printing methods used, and statistical analysis showed a significant difference (p3D printed models, particularly using multiple print materials, were considered useful by CHPs for preoperative planning, as well as other applications such as teaching and training. This study suggests that, with further advances in 3D modelling and printing technology, patient-specific 3D MV models could serve as a useful clinical tool. The findings also highlight the potential of this technology to be applied in a variety of medical areas within both clinical and educational settings.

    Carbapenemase-producing Enterobacteriaceae are increasing worldwide. Rectal screening for these bacteria can inform the management of infected and colonized patients, especially those admitted to intensive care units (ICUs). A laboratory developed, qualitative duplex real-time polymerase chain reaction assay for rapid detection of OXA-48-like and VIM producing Enterobacteriaceae, performed on rectal swabs, was designed and evaluated in an intensive care unit with endemic presence of OXA-48. During analytical assay validation, no cross-reactivity was observed and 100% sensitivity and specificity were obtained for both bla OXA-48-like and bla VIM in all spiked clinical samples. During the clinical part of the study, the global sensitivity and specificity of the real-time PCR assay for OXA-48 detection were 95.7% and 100% (P=0.1250), respectively, in comparison with culture; no VIM-producing Enterobacteriaceae were detected. Clinical features of patients in the ICU who were colonized or infected with OXA-48 producing Enterobacteriaceae, including outcome, were analyzed. Most had severe underlying conditions, and had risk factors for colonization with carbapenemase-producing Enterobacteriaceae before or during ICU admission, such as receiving previous antimicrobial therapy, prior healthcare exposure (including long-term care), chronic disease, immunosuppression and/or the presence of an intravascular catheter and/or mechanical ventilation device. The described real-time PCR assay is fast (~2-3hours, if DNA extraction is included), simple to perform and results are easy to interpret, features which make it applicable in the routine of clinical microbiology laboratories. Implementation in endemic hospitals could contribute to early detection of patients colonized by OXA-48 producing Enterobacteriaceae and prevention of their spread. Copyright © 2017 Elsevier Inc.

    The Minority University Research and Education Program (MUREP) NASA Innovations in Climate Education (NICE) project advances NASA's Office of Education's strategic initiative to improve the quality of the nation's Science, Technology, Engineering and Mathematics (STEM) education and enhance literacy about climate and other Earth systems environmental changes. NICE also strategically supports the United States' progressive initiative to enhance the science and technology enterprise for successful competition in the 21st century global community. To extend to wider networks in 2013, MUREP NICE partnered with the NASA Digital Learning Network (DLNTM) in a unique, non-traditional collaborative model to significantly increase the impact and connection with formal and informal educators, curriculum developers, science education specialists, and researchers regarding climate literacy. DLN offers an expansive distance learning capability that bridges presenters with education audiences for interactive, web-based, synchronous and asynchronous Educator Professional Development (EPD). DLN services over 10,000 educators each year. In 3rd quarter FY13 alone DLN totaled 3,361 connections with educators. The DLN allows for cost effective (no travel) engagement of multiple geographically dispersed audiences with presenters from remote locations. This facilitates interactive communication among participants through distance education, allowing them to share local experiences with one another. A comprehensive four-part EPD workshop, featuring several NICE Principal Investigators (PI) and NASA subject matter experts was developed for NICE in April 2013. Topics covered in the workshop progressed from a simple introduction of Earth's energy budget, through explanation of temperature data collection and evidence of temperature rise, impacts on phenology, and finally consequences for bugs and birds. This event was an innovative hybrid workshop, connecting onsite teachers interactively

    Patients with epilepsy often have a structural cause for their seizures and may benefit from surgical resection. As recommended in the National Institute of Health and Clinical Excellence (NICE) guidelines, magnetic resonance imaging (MRI) is used to screen for structural abnormalities in these patients and there is increasing evidence that 3T MRI has better sensitivity and specificity than 1.5T. This article reviews the imaging findings of many of the common diseases that can cause epilepsy.

    2016-03-25

    All health care systems face the need to find the resources to meet new demands such as a new, cost-increasing health technology. In England and Wales, when a health technology is recommended by the National Institute for Health and Care Excellence (NICE), the National Health Service (NHS) is mandated to provide the funding to accommodate it within three months of publication of the recommendation. Identifying what, in practice, is foregone when new cost-increasing technologies are introduced is important for understanding the effects of health technology assessment (HTA) decisions on the NHS or any other health care system. Our objective was to investigate how in practice local NHS commissioners in Wales accommodated financial "shocks" arising from technology appraisals (TAs) issued by NICE and from other cost pressures. Semi-structured interviews were conducted with Finance Directors and Medical Directors from all seven Local Health Boards (LHBs) in NHS Wales. These interviews covered prioritisation processes, as well as methods of financing NICE TAs and other financial shocks at each LHB. We then undertook a systematic identification of themes and topics from the information recorded. The study relates to the period October 2010 to March 2013. The financial impact of NICE TAs is generally anticipated and planned for in advance and the majority of LHBs have contingency funds available to cope with these and other financial shocks within-period. Efficiency savings (defined as reductions in costs with no assumed reductions in quality) were a source of funds for cost pressures of all kinds. Service displacements were not linkable to particular NICE TAs and there appears to be a general lack of explicit prioritisation activities. The Welsh Government has, on occasion, explicitly or implicitly acted as the funder of last resort. Services may be displaced as part of a response to the cumulative impact of all types of cost pressures, including cost-increasing health

  14. 'Nice girls don't': women and the condom conundrum.

    Science.gov (United States)

    Cook, Catherine

    2012-02-01

    This study aims to highlight the tensions between the 'risks' of condom negotiation to feminine identity and safer sex health education messages of individual choice and responsibility. Effective education incorporates nurses' recognition that deterrents to women practising safer sex may increase subsequent to a diagnosis of a viral sexually transmitted infection. Health educational messages and clinicians' teaching emphasise rational decision-making with regard to condom use with a focus on the acquisition of technical information and ready access to condoms. These messages do not take into account the social complexities for women in negotiating condom use with men that deter condom use. A qualitative, feminist post-structuralist research design was used. In-depth email interviews were conducted with 12 clinicians with expertise in the sexual health field and 26 women with a diagnosis of either herpes simplex virus or human papilloma virus. A thematic analysis approach was used to analyse the semi-structured and interactive interviews. Few women in the study had received any direct safer sex education from clinicians and wanted them to initiate this discussion. Most women found the topic of safer sex became more difficult once diagnosed with a viral sexually transmitted infection. Women's dilemmas were whether to disclose the diagnosis as part of insisting on condom use, whether condom use mitigated the obligation to disclose or whether any talk or condom use was avoided as too 'risky' to feminine identity. Paradoxically, it may be harder for women to negotiate safer sex and ask for condoms to be used, once diagnosed with a viral sexually transmitted infection. Women want clinicians to give advice about the dissonance between 'rational' safer sex messages and social expectations of appropriate femininity. Relevance to clinical practice.  Nurses have a key role in engaging with women in considering safer sex practices. Nurses need to be able to demonstrate to

  15. Chest Tomosynthesis: Technical Principles and Clinical Update

    Science.gov (United States)

    Dobbins, James T.; McAdams, H. Page

    2009-01-01

    Digital tomosynthesis is a radiographic technique that can produce an arbitrary number of section images of a patient from a single pass of the x-ray tube. It utilizes a conventional x-ray tube, a flat-panel detector, a computer-controlled tube mover, and special reconstruction algorithms to produce section images. While it does not have the depth resolution of computed tomography (CT), tomosynthesis provides some of the tomographic benefits of CT but at lower cost and radiation dose than CT. Compared to conventional chest radiography, chest tomosynthesis results in improved visibility of normal structures such as vessels, airway and spine. By reducing visual clutter from overlying normal anatomy, it also enhances detection of small lung nodules. This review article outlines the components of a tomosynthesis system, discusses results regarding improved lung nodule detection from the recent literature, and presents examples of nodule detection from a clinical trial in human subjects. Possible implementation strategies for use in clinical chest imaging are discussed. PMID:19616909

    Full Text Available Aim: To assess the prevalence of antimicrobial resistance producing extended-spectrum β-lactamases (ESBL (blaTEM, blaSHV, and blaCTX-M genes in Escherichia coli isolated from chicken meat, chevon meat, raw milk, and human urine and stool samples collected from tribal districts of Chhattisgarh, viz., Jagdalpur, Dantewada, Kondagaon, and Kanker. Materials and Methods: A total of 330 samples, comprising 98 chicken meat, 82 chevon meat, 90 raw milk, and 60 human urine and stool samples, were processed for isolation of E. coli. Isolates were confirmed biochemically and further tested against commonly used antibiotics to know their resistant pattern. The resistant isolates were tested for ESBL production by phenotypic method followed by characterization with molecular method using multiplex-polymerase chain reaction technique. Results: Overall 57.87% (191/330 samples were found positive for E. coli, which include 66.32% (65/98 chicken meat, 46.34% (38/82 chevon meat, 81.11% (73/90 raw milk, and 25% (15/60 human urine and stool samples. Isolates showed the highest resistance against cefotaxime (41.36% followed by oxytetracycline (34.03%, ampicillin (29.31%, cephalexin (24.60%, cefixime (16.75%, and ceftazidime (13.08%. Phenotypic method detected 10.99% (21/191 isolates as presumptive ESBL producers, however, molecular method detected 3.66% (7/191, 2.09% (4/191, and 0.00% (0/191 prevalence of blaTEM, blaCTX-M, and blaSHV, respectively. Conclusion: The present study indicates a high prevalence of E. coli in raw chicken meat, chevon meat, and milk due to poor hygienic practices. The antibiotic susceptibility test detected the presence of the resistance pattern against ESBL in E. coli isolated from raw chicken meat, chevon meat, milk, and also in human clinical samples is of great concern. The appearance of E. coli in the human food chain is alarming and requires adaptation of hygienic practices and stipulate use of antibiotics.

    Wilson's disease of cerebral type with a chief complaint of tremor occurred in 3 brothers and sisters of a certain family line. Treatment with D-penicillamine produced remarkable clinical improvement as shown by the disappearance of tremor and Kayser-Fleischer ring. Cranial CT scans made before the treatment revealed abnormal findings such as low density areas in the (bilateral) thalamus and the lenticular nucleus, atrophy of the cerebral cortex, and enlargement of the ventricles. After the treatment, cranial CT revealed that the low density areas in the thalamus and the lenticular nucleus disappeared corresponding to the clinical improvement. However, the atrophy of the cerebral cortex and the enlargement of the ventricles were not ameliorated. (Ueda, J.)

    With the recent emergence of positron emission tomography (PET) as a viable clinical tool, there is a need for a convenient, cost-effective source of the positron emitter-labeled radiotracers labeled with carbon-11, nitrogen-13, oxygen-15, and fluorine-18. These short-lived radioisotopes are accelerator produced and thus, require a cyclotron and radiochemistry processing instrumentation that can be operated 3 in a clinical environment by competant technicians. The basic goal is to ensure safety and reliability while setting new standards for economy and ease of operation. The Siemens Radioisotope Delivery System (RDS 112) is a fully automated system dedicated to the production and delivery of positron-emitter labeled precursors and radiochemicals required to support a clinical PET imaging program. Thus, the entire RDS can be thought of as an automated radiochemical processing apparatus

    Full Text Available Rapid identification of yeast infections is helpful in prompt appropriate antifungal therapy. In the present study, the usefulness of chromogenic medium, slide culture technique and Vitek2 Compact (V2C has been analysed. A total of 173 clinical isolates of yeast species were included in the study. An algorithm to identify such isolates in routine clinical microbiology laboratory was prepared and followed. Chromogenic medium was able to identify Candida albicans, C. tropicalis, C. krusei, C. parapsilosis and Trichosporon asahii. Chromogenic medium was also helpful in identifying "multi-species" yeast infections. The medium was unable to provide presumptive identification of C. pelliculosa, C. utilis, C. rugosa, C. glabrata and C. hemulonii. Vitek 2 compact (V2C differentiated all pseudohypae non-producing yeast species. The algorithm followed was helpful in timely presumptive identification and final diagnosis of yeast infections, including multi-species yeast infections.

    Full Text Available Abstract Background Lithium is a commonly prescribed drug with a narrow therapeutic index, and recognised adverse effects on the kidneys and thyroid. Clinical guidelines for the management of bipolar affective disorder published by The National Institute for Health and Clinical Excellence (NICE recommend checks of renal and thyroid function before lithium is prescribed. They further recommend that all patients who are prescribed lithium should have their renal and thyroid function checked every six months, and their serum lithium checked every three months. Adherence to these recommendations has not been subject to national UK audit. Methods The Prescribing Observatory for Mental Health (POMH-UK invited all National Health Service Mental Health Trusts in the UK to participate in a benchmarking audit of lithium monitoring against recommended standards. Data were collected retrospectively from clinical records and submitted electronically. Results 436 clinical teams from 38 Trusts submitted data for 3,373 patients. In patients recently starting lithium, there was a documented baseline measure of renal or thyroid function in 84% and 82% respectively. For patients prescribed lithium for a year or more, the NICE standards for monitoring lithium serum levels, and renal and thyroid function were met in 30%, 55% and 50% of cases respectively. Conclusions The quality of lithium monitoring in patients who are in contact with mental health services falls short of recognised standards and targets. Findings from this audit, along with reports of harm received by the National Patient Safety Agency, prompted a Patient Safety Alert mandating primary care, mental health and acute Trusts, and laboratory staff to work together to ensure systems are in place to support recommended lithium monitoring by December 2010.

    To diagnose a patient with a failing visual system, it is necessary to localize the site of the lesion in the system, and identify the etiology that has produced it. Physicians do not see diseases but just their manifestations. Clinical neuro-ophthalmology provides the basic principles on how to progress from manifestations to the diseases they indicate. The Frank B. Walsh Neuro-Ophthalmology Society (the Walsh Society) that originated in 1969 in the United States has been the center of clinical neuro-ophthalmology case studies throughout the world. In Japan, the Ronald M. Burde Clinical Neuro-Ophthalmology Study Group (the RMB Society) was organized in 2001 to establish and promote a clinicopathologic conference in the style of the Walsh Society. On this occasion, Prof. Burde was invited to the Annual Japanese Ophthalmological Society meeting. Based on some illustrative cases presented at the annual meetings of the RMB society, this review was carried out to present the current knowledge of clinical neuro-ophthalmology. (author)

    To assess the potency of the PPD-mallein produced in Brazil, five animals were from a property identified as a focus of glanders. These animals had suggestive clinical signs of the disease and the other five, from a property free from glanders, showed no clinical signs and were serology negative (control group). PPD-mallein from Burkholderia mallei was obtained by precipitation with trichloroacetic acid and ammonium sulfate. The animals were inoculated according to the criteria established by Department of Agriculture, Livestock and Supply (MAPA) for the diagnosis of glanders. After 48 h of application of PPD-mallein, there was swelling in the area of application, presence of ocular secretion and tears in sick animals. The control group showed no inflammatory reaction at the site of inoculation of PPD-mallein. This immunogen produced in Brazil and still being tested was effective for identifying the infection in true positive animals and excluding the truly negative ones, being a new possibility for diagnosis and control of glanders.

  6. Value based pricing, research and development, and patient access schemes. Will the United Kingdom get it right or wrong?

    2010-09-01

    The National Health Service (NHS) should reward innovation it values. This will enable the NHS and the United Kingdom (UK) economy to benefit and impact positively on the Research and Development (R&D) decision making of companies. The National Institute for Health and Clinical Excellence (NICE) currently seeks to do this on behalf of the NHS. Yet the Office of Fair Trading proposals for Value Based Pricing add price setting powers--initially for the Department of Health (DH) and then for NICE. This introduces an additional substantial uncertainty that will impact on R&D and, conditional on R&D proceeding, on launch (or not) in the UK. Instead of adding to uncertainty the institutional arrangements for assessing value should seek to be predictable and science based, building on NICE's current arrangements. The real challenge is to increase understanding of the underlying cost-effectiveness of the technology itself by collecting evidence alongside use. The 2009 Pharmaceutical Price Regulation Scheme sought to help do this with Flexible Pricing (FP) and Patient Access Schemes (PASs). The PASs to date have increased access to medicines, but no schemes proposed to date have yet helped to tackle outcomes uncertainty. The 2010 Innovation Pass can also be seen as a form of 'coverage with evidence development.' The NHS is understandably concerned about the costs of running such evidence collection schemes. Enabling the NHS to deliver on such schemes will impact favourably on R&D decisions. Increasing the uncertainty in the UK NHS market through government price setting will reduce incentives for R&D and for early UK launch.

    Clinical trials are often described as machine-like systems for generating specific information concerning drug safety and efficacy, and are understood as a component of the industrial drug development processes. This paper argues that contemporary clinical trials in oncology are not reducible to mere drug testing. Drawing on ethnographic fieldwork and interviews with researchers in the field of oncology from 2010 to 2013, we introduce a conceptual contrast between trials as testing machines and trials as clinical experimental systems to draw attention to the ways trials are increasingly being used to ask open-ended scientific questions. When viewed as testing machines, clinical trials are seen as a means to produce answers to straightforward questions and deviations from the protocol are seen as bugs in the system; but practitioners can also treat trials as clinical experimental systems to investigate as yet undefined problems and where heterogeneity becomes a means to produce novel biological or clinical insights. The rise of "biomarker-driven" clinical trials in oncology, which link measurable biological characteristics such as genetic mutations to clinical features such as a patient's response to a particular drug, exemplifies a trend towards more experimental styles of clinical work. These transformations are congruent with changes in the institutional structure of clinical research in oncology, including a movement towards more flexible, networked research arrangements, and towards using individual patients as model systems for asking biological questions.

    Full Text Available Proteus spp. are opportunistic multidrug resistant enterobacteria associated with diverse clinical diseases in domestic animals. However, Proteus infections in domestic animals are often misdiagnosed or considered contaminants in microbiological cultures rather than a primary agent of disease. Descriptions of Proteus infections in domestic animals are typically restricted to case reports, retrospective studies, or surveillance of other microorganisms. The present study investigated multiple antibiotic resistance indices, minimum inhibitory concentrations (MICs, and ESBL production in 73 strains of Proteus mirabilis (n = 69 and Proteus vulgaris (n = 4 isolated from domestic animals with various clinical manifestations. In dogs, the pathogen was most commonly associated with cystitis (48.21, enteritis (21.42%, otitis (14.29%, and conjunctivitis (3.57%. In bovines, the microorganism was predominant in cases of enteritis (22.22%, abscess (11.11%, otitis (11.11%, omphalitis (11.11%, and peritonitis (11.11%, and in organ fragments (11.11%. In equines (50.0% and cats (100.0%, diarrhea was the main clinical sign. In vitro standard disk diffusion assay showed that the most effective antimicrobials against the isolates were imipenem (98.63, norfloxacin (95.89, amikacin (95.89, levofloxacin (90.41, ceftriaxone (87.64, and florfenicol (87.67. In contrast, the isolates commonly showed resistance to novobiocin (95.89, azithromycin (57.53, and trimethropim/sulfamethoxazole (39.73. Among the 73 isolates, the efficacy of amoxicillin/clavulanic acid, gentamicin, ceftriaxone, and ciprofloxacin according to MICs was 87.67%, 86.30%, 84.93%, and 82.19%, respectively. The MIC50 values of amoxicillin/clavulanic acid, ceftriaxone, ciprofloxacin, and gentamicin were, respectively, 1.0, 0.004, 0.03, and 1.0 µg/mL. Thirty-three strains (45.21% showed a antimicrobial multiple resistance index of ? 0.3. Multidrug resistance profiles of isolates were observed most frequently

    Full Text Available Abstract Background The National Health Service (NHS was tasked in 2001 with developing service provision to prevent falls in older people. We carried out a national survey to provide a description of health and social care funded UK fallers services, and to benchmark progress against current practice guidelines. Methods Cascade approach to sampling, followed by telephone survey with senior member of the fall service. Characteristics of the service were assessed using an internationally agreed taxonomy. Reported service provision was compared against benchmarks set by the National Institute for Health and Clinical Excellence (NICE. Results We identified 303 clinics across the UK. 231 (76% were willing to participate. The majority of services were based in acute or community hospitals, with only a few in primary care or emergency departments. Access to services was, in the majority of cases, by health professional referral. Most services undertook a multi-factorial assessment. The content and quality of these assessments varied substantially. Services varied extensively in the way that interventions were delivered, and particular concern is raised about interventions for vision, home hazard modification, medication review and bone health. Conclusion The most common type of service provision was a multi-factorial assessment and intervention. There were a wide range of service models, but for a substantial number of services, delivery appears to fall below recommended NICE guidance.

    The aim of the study was to examine antibacterial properties of microemulsion structure produced from Aloe vera var. littoralis extract as a new tool of nanoscale drug-like materials. Aloe vera var. littoralis ( A. littoralis ) extract was prepared by distillation method. A nonocarrier structure in the microemulsion system was prepared from the extract. Serial concentrations were prepared from 8 mg/mL extract and the nonocarrier containing 0.1 mg/mL pure extract and were evaluated by a disk diffusion method for 35 Salmonella clinical isolates. Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were determined by microbroth dilution assay using MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) method by an enzyme-linked immunosorbent assay(ELISA) Microplate Reader apparatus. Antioxidant activity of the extract was determined by measuring the ferric reducing ability of plasma (FRAP) assay. From 35 clinical isolates of Salmonella , 17 isolates-including resistant isolates of S.E.1103 and S.E.49-had a zone of inhibition (ZI) of 7 to 32 mm in 0.007 mg/mL of the extract. S.E.76 isolate exposed to 30 µg/mL ceftazidime disk had a ZI of 12 mm but had 10 mm in 7µg/mL of A. littoralis extract. The inhibitory effect of a nanocarrier at a concentration of 25 µg/mL by 20 mm ZI was comparable by the ceftazidime (30 µg/mL) effect. MIC 50 was 0.25 mg/mL and MBC 50 was 0.5 mg/mL by MTT method for the extract. It was shown that A.littoralis extract had antioxidant activity of 31.67 µM/mg that could be increased based on concentration. It was concluded that the nanocarrier had a significant effect on the studied isolates in comparison with ordinary antibiotics and had potential for use as a natural antioxidant and antimicrobial material in complementary medicine.

    2014-01-01

    Full Text Available Neurocysticercosis is a serious endemic zoonosis resulting in increased cases of seizure and epilepsy in humans. The genesis of clinical manifestations of the disease through experimental animal models is poorly exploited. The monkeys may prove useful for the purpose due to their behavior and cognitive responses mimicking man. In this study, neurocysticercosis was induced in two rhesus monkeys each with 12,000 and 6,000 eggs, whereas three monkeys were given placebo. The monkeys given higher dose developed hyperexcitability, epileptic seizures, muscular tremors, digital cramps at 10 DPI, and finally paralysis of limbs, followed by death on 67 DPI, whereas the monkeys given lower dose showed delayed and milder clinical signs. On necropsy, all the infected monkeys showed numerous cysticerci in the brain. Histopathologically, heavily infected monkeys revealed liquefactive necrosis and formation of irregular cystic cavities lined by atrophied parenchymal septa with remnants of neuropil of the cerebrum. In contrast, the monkeys infected with lower dose showed formation of typical foreign body granulomas characterized by central liquefaction surrounded by chronic inflammatory response. It was concluded that the inflammatory and immune response exerted by the host against cysticerci, in turn, led to histopathological lesions and the resultant clinical signs thereof.

    The aim was to investigate the cost-effectiveness of interventional treatment for varicose veins (VV) in the UK NHS, and to inform the national clinical guideline on VV, published by the National Institute of Health and Care Excellence. An economic analysis was constructed to compare the cost-effectiveness of surgery, endothermal ablation (ETA), ultrasound-guided foam sclerotherapy (UGFS), and compression stockings (CS). The analysis was based on a Markov decision model, which was developed in consultation with members of the NICE guideline development group (GDG). The model had a 5-year time horizon, and took the perspective of the UK National Health Service. Clinical inputs were based on a network meta-analysis (NMA), informed by a systematic review of the clinical literature. Outcomes were expressed as costs and quality-adjusted life years (QALYs). All interventional treatments were found to be cost-effective compared with CS at a cost-effectiveness threshold of £20,000 per QALY gained. ETA was found to be the most cost-effective strategy overall, with an incremental cost-effectiveness ratio of £3,161 per QALY gained compared with UGFS. Surgery and CS were dominated by ETA. Interventional treatment for VV is cost-effective in the UK NHS. Specifically, based on current data, ETA is the most cost-effective treatment in people for whom it is suitable. The results of this research were used to inform recommendations within the NICE guideline on VV. Copyright © 2015 European Society for Vascular Surgery. Published by Elsevier Ltd.

    International data on the molecular epidemiology of Enterobacteriaceae with VIM carbapenemases are limited. We performed short read (Illumina) WGS on a global collection of 89 VIM-producing clinical Enterobacteriaceae (2008-14). VIM-producing (11 varieties within 21 different integrons) isolates were mostly obtained from Europe. Certain integrons with bla VIM were specific to a country in different species and clonal complexes (CCs) (In 87 , In 624 , In 916 and In 1323 ), while others had spread globally among various Enterobacteriaceae species (In 110 and In 1209 ). Klebsiella pneumoniae was the most common species ( n  = 45); CC147 from Greece was the most prevalent clone and contained In 590 -like integrons with four different bla VIM s. Enterobacter cloacae complex was the second most common species and mainly consisted of Enterobacter hormaechei ( Enterobacter xiangfangensis , subsp. steigerwaltii and Hoffmann cluster III). CC200 (from Croatia and Turkey), CC114 (Croatia, Greece, Italy and the USA) and CC78 (from Greece, Italy and Spain) containing bla VIM-1 were the most common clones among the E. cloacae complex. This study highlights the importance of surveillance programmes using the latest molecular techniques in providing insight into the characteristics and global distribution of Enterobacteriaceae with bla VIM s. © The Author 2017.

    2015-06-01

    We present noise-immune cavity-enhanced optical frequency comb spectroscopy (NICE-OFCS), a recently developed technique for sensitive, broadband, and high resolution spectroscopy. In NICE-OFCS an optical frequency comb (OFC) is locked to a high finesse cavity and phase-modulated at a frequency precisely equal to (a multiple of) the cavity free spectral range. Since each comb line and sideband is transmitted through a separate cavity mode in exactly the same way, any residual frequency noise on the OFC relative to the cavity affects each component in an identical manner. The transmitted intensity contains a beat signal at the modulation frequency that is immune to frequency-to-amplitude noise conversion by the cavity, in a way similar to continuous wave noise-immune cavity-enhanced optical heterodyne molecular spectroscopy (NICE-OHMS). The light transmitted through the cavity is detected with a fast-scanning Fourier-transform spectrometer (FTS) and the NICE-OFCS signal is obtained by fast Fourier transform of the synchronously demodulated interferogram. Our NICE-OFCS system is based on an Er:fiber femtosecond laser locked to a cavity with a finesse of ˜9000 and a fast-scanning FTS equipped with a high-bandwidth commercial detector. We measured NICE-OFCS signals from the 3νb{1}+νb{3} overtone band of CO_2 around 1.57 μm and achieved absorption sensitivity 6.4×10-11cm-1 Hz-1/2 per spectral element, corresponding to a minimum detectable CO_2 concentration of 25 ppb after 330 s integration time. We will describe the principles of the technique and its technical implementation, and discuss the spectral lineshapes of the NICE-OFCS signals. A. Khodabakhsh, C. Abd Alrahman, and A.

    This study explored third-semester baccalaureate nursing students' perceptions of the value of using student-produced video as an approach for learning head-to-toe assessment, an essential clinical nursing skill taught in the classroom. A cognitive apprenticeship model guided the study. The researchers developed a 34-item survey. A convenience sample of 72 students enrolled in an applied assessment and nursing fundamentals course at a university in the western United States provided the data. Most students reported a videotaping process that worked, supportive faculty, valuable faculty review of their work, confidence, a sense of performance independence, the ability to identify normal assessment findings, and few barriers to learning. The results suggested that a student-produced video approach to learning head-to-toe assessment was effective. Further, the study demonstrated how to leverage available instructional technology to provide meaningful, personalized instruction and feedback to students about an essential nursing skill.

    Uranium producers came alive in August, helping spot prices crack the $8.00 barrier for the first time since March. The upper end of NUKEM's price range actually finished the month at $8.20. Scrambling to fulfill their long-term delivery contracts, producers dominate the market. In the span of three weeks, five producers came out for 2 million lbs U3O8, ultimately buying nearly 1.5 million lbs. One producer accounted for over half this volume. The major factor behind rising prices was that producers required specific origins to meet contract obligations. Buyers willing to accept open origins created the lower end of NUKEM's price range

  3. Investigating antibiotic resistance in non-clinical environments

    Full Text Available There have been many calls for more information about the natural resistome and these have also highlighted the importance of understanding the soil resistome in the preservation of antibiotics for the treatment of infections. However, to date there have been few studies which have investigated the culturable soil resistome, which highlights the difficulties faced by microbiologists in designing these experiments to produce meaningful data. The World Health Organization definition of resistance is the most fitting to non-clinical environmental studies: Antimicrobial resistance is resistance of a microorganism to an antimicrobial medicine to which it was previously sensitive. The ideal investigation of non-clinical environments for antibiotic resistance of clinical relevance would be using standardized guidelines and breakpoints. This review outlines different definitions and methodologies used to understand antibiotic resistance and suggests how this can be performed outside of the clinical environment.

Caffeine has occasionally been considered a drug of abuse and the potential for dependence on caffeine has been debated. Presently, due to a paucity of clinical evidence on caffeine dependence or abuse, no such diagnosis is included in the Diagnostic and Statistical Manual of Mental Disorder-fourth edition. The authors present two cases of abuse or dependence on the caffeine contained in 'eutrophic' (energy/nutritional) beverages or caffeine preparations, followed by a review of clinical studies demonstrating evidence that some people can manifest a clinical syndrome of caffeine dependence or abuse. The cases suggest that caffeine can produce a clinical dependence syndrome similar to those produced by other psychoactive substances and has a potential for abuse. In a recent study using a structured interview and the Diagnostic and Statistical Manual of Mental Disorder-fourth edition criteria for substance dependence and abuse, a subset of the general population was found to demonstrate caffeine dependence or caffeine abuse. Therefore, the authors propose that companies or businesses manufacturing or marketing caffeine or products containing caffeine must meet the following guidelines: (i) clearly indicate the caffeine content of products containing comparatively higher quantities of caffeine; (ii) warn that such products should be avoided by infants and children wherever possible, and inform adult consumers about the precise quantity of caffeine that is considered safe for consumption; and (iii) clearly state that consuming large quantities of caffeine and the long-term use of caffeine carry health risks.

    Escherichia coli is commonly involved in infections with a heavy bacterial burden. Piperacillin-tazobactam and carbapenems are among the recommended empirical treatments for health care-associated complicated intra-abdominal infections. In contrast to amoxicillin-clavulanate, both have reduced in vitro activity in the presence of high concentrations of extended-spectrum β-lactamase (ESBL)-producing and non-ESBL-producing E. coli bacteria. Our goal was to compare the efficacy of these antimicrobials against different concentrations of two clinical E. coli strains, one an ESBL-producer and the other a non-ESBL-producer, in a murine sepsis model. An experimental sepsis model {~5.5 log10 CFU/g [low inoculum concentration (LI)] or ~7.5 log(10) CFU/g [high inoculum concentration (HI)]} using E. coli strains ATCC 25922 (non-ESBL producer) and Ec1062 (CTX-M-14 producer), which are susceptible to the three antimicrobials, was used. Amoxicillin-clavulanate (50/12.5 mg/kg given intramuscularly [i.m.]), piperacillin-tazobactam (25/3.125 mg/kg given intraperitoneally [i.p.]), and imipenem (30 mg/kg i.m.) were used. Piperacillin-tazobactam and imipenem reduced spleen ATCC 25922 strain concentrations (-2.53 and -2.14 log10 CFU/g [P imipenem, and amoxicillin-clavulanate, respectively, although imipenem and amoxicillin-clavulanate were more efficacious than piperacillin-tazobactam). An adapted imipenem treatment (based on the time for which the serum drug concentration remained above the MIC obtained with a HI of the ATCC 25922 strain) improved its efficacy to -1.67 log10 CFU/g (P imipenem treatment of infections caused by ESBL- and non-ESBL-producing E. coli strains in patients with therapeutic failure with piperacillin-tazobactam.

    In clinical practice, delays in obtaining culture results impact patient care and the ability to tailor antibiotic therapy. Despite the advancement of rapid molecular diagnostics, the use of plate cultures inoculated from swab samples continues to be the standard practice in clinical care. Because the inoculation culture process can take between 24 and 48h before a positive identification test can be run, there is an unmet need to develop rapid throughput methods for bacterial identification. Previous work has shown that pyocyanin can be used as a rapid, redox-active biomarker for identifying Pseudomonas aeruginosa in clinical infections. However, further validation is needed to confirm pyocyanin production occurs in all clinical strains of P. aeruginosa. Here, we validate this electrochemical detection strategy using clinical isolates obtained from patients with hospital-acquired infections or with cystic fibrosis. Square-wave voltammetric scans of 94 different clinical P. aeruginosa isolates were taken to measure the concentration of pyocyanin. The results showed that all isolates produced measureable concentrations of pyocyanin with production rates correlated with patient symptoms and comorbidity. Further bioinformatics analysis confirmed that 1649 genetically sequenced strains (99.9%) of P. aeruginosa possess the two genes (PhzM and PhzS) necessary to produce pyocyanin, supporting the specificity of this biomarker. Confirming the production of pyocyanin by all clinically-relevant strains of P. aeruginosa is a significant step towards validating this strategy for rapid, point-of-care diagnostics.

    Shiga toxin (Stx)-producing Escherichia coli (STECs) cause non-bloody diarrhea, hemorrhagic colitis, and hemolytic uremic syndrome, and are the primary cause of acute renal failure in children worldwide. This study investigated the correlation of genetic makeup of STEC strains as revealed by DNA microarray to clinical symptoms and the duration of STEC shedding. All STEC isolated (n = 96) from patients <10 years of age in Jönköping County, Sweden from 2003 to 2015 were included. Isolates were characterized by DNA microarray, including almost 280 genes. Clinical data were collected through a questionnaire and by reviewing medical records. Of the 96 virulence genes (including stx) in the microarray, 62 genes were present in at least one isolate. Statistically significant differences in prevalence were observed for 21 genes when comparing patients with bloody diarrhea (BD) and with non-bloody stool (18 of 21 associated with BD). Most genes encode toxins (e.g., stx2 alleles, astA, toxB), adhesion factors (i.e. espB_O157, tir, eae), or secretion factors (e.g., espA, espF, espJ, etpD, nleA, nleB, nleC, tccP). Seven genes were associated with prolonged stx shedding; the presence of three genes (lpfA, senB, and stx1) and the absence of four genes (espB_O157, espF, astA, and intI1). We found STEC genes that might predict severe disease outcome already at diagnosis. This can be used to develop diagnostic tools for risk assessment of disease outcome. Furthermore, genes associated with the duration of stx shedding were detected, enabling a possible better prediction of length of STEC carriage after infection.<
