Is the doctor in? PhD to professional: complementary perspectives in research libraries

Aim: This paper considers how changes in the research landscape are simultaneously changing the skills needs of library staff, and opening up new opportunities for researchers to pursue careers within libraries. It explores what skills, competencies and knowledge staff with doctoral qualifications can bring to library research support services. Context: Librarians working in research support areas need different skills to the skills academic librarians have traditionally needed. There is currently a gap in the training which those undertaking professional librarianship qualifications receive, in relation to the skills needed for research roles. Simultaneously, expansion in the numbers of PhD students in the UK in recent years has been accompanied by the professionalisation of researcher skills development, equipping students with transferable skills for careers outside, as well as inside, academia. Methodology: This paper compares the skills’ needs of research librarians with the competencies and skills of doctoral graduates, specifically in the UK context (as articulated in the Vitae Researcher Development Framework). It also surveys and discusses the skill-set and qualifications of research support staff employed at three UK research libraries. Results: Understanding the needs and, importantly, the behaviours, of researchers is integral to the provision of a successful library research support service. Many of the skills which are necessary for library graduates to have, are those that are already identified as essential researcher skills. The peer-level support offered by library staff with research backgrounds has a role in developing stronger relationships between the library and the academy

Genetic susceptibility to psoriasis: an emerging picture

Psoriasis is recognized as a complex disease for which multiple genetic and non-genetic factors influence susceptibility. The major susceptibility locus resides in the MHC class I region and, until relatively recently, evidence for non-MHC loci was inconsistent. Like many common diseases, knowledge of the genetic basis of this condition has been advanced dramatically in recent times with the advent of genome-wide association studies using single nucleotide polymorphisms. Here, we give an overview of current knowledge of genetic risk factors for psoriasis and consider emerging studies that may further add to our understanding of the genetic basis of the disease

Efficacy of a fixed combination of calcipotriol/betamethasone dipropionate topical gel in adult patients with mild to moderate psoriasis: blinded interim analysis of a phase IV, multicenter, randomized, controlled, prospective study

Background: Psoriasis is a common, chronic, inflammatory skin disease with the majority of individuals having limited disease, treated with topical medication. However, special attributes of topical treatments like galenic/cosmetic properties or an inconvenient treatment schedule may result in low preference for topical treatments. Hence, there is strong medical need for a topical medication, which is highly efficacious, easy-to-use and preferred by both physicians and patients. Objective: Blinded interim analysis with the purpose to assess efficacy of (both from the physician's and patient's perspective) and the patients' preference with a highly efficacious and easy-to-use fixed combination of calcipotriol/betamethasone dipropionate topical gel after 8 weeks of once daily treatment in a large patient population. Methods: In this phase IV, international, multicentre, randomized, controlled, prospective, parallel group study, adult patients with active, mild to moderate psoriasis despite previous topical psoriasis treatment, i.e. unsuccessful in the 8 weeks preceding study participation, are followed over 64 weeks. During the first 8 weeks the patients apply their medication once a day followed by a 56-weeks maintenance period according to SmPC. Blinded interim analysis of all patients included demographics, Physician's Global Assessment, the novel Patient's self Global Assessment (PsGA) and Patient Preference Questionnaire (PPQ). Results: 1795 patients were analysed. At week 8, 36.5% of the physicians rated the patients' psoriasis as clear/almost clear. Similarly, based on the patients' self-assessment, 34.2% had a clear/almost clear score of PsGA in week 8. Analysis of the PPQ showed that the vast majority of the patients judged their 8-week treatment to be preferable compared with their previous treatments. Conclusion: Results of this blinded interim analysis indicate that the fixed combination of calcipotriol/betamethasone dipropionate gel is highly efficacious and preferred by the majority of analysed patients

Heterotopic ossification after patellar tendon repair in a man with trisomy 8 mosaicism: a case report and literature review

<p>Abstract</p> <p>Introduction</p> <p>Heterotopic ossification is the abnormal formation of lamellar bone in soft tissue. Its presence jeopardizes functional outcome, impairs rehabilitation and increases costs due to subsequent surgical interventions.</p> <p>Case presentation</p> <p>We present a case of a 32-year-old African-American man with trisomy 8 mosaicism who developed severe heterotopic ossification of his right extensor mechanism subsequent to repair of a patellar tendon rupture.</p> <p>Conclusion</p> <p>To the best of our knowledge there are no prior reports of heterotopic ossification as a complication of patellar tendon repair. This case may suggest an association between trisomy 8 mosaicism and increased risk of heterotopic ossification.</p

Nanopods: A New Bacterial Structure and Mechanism for Deployment of Outer Membrane Vesicles

Background: Bacterial outer membrane vesicles (OMV) are packets of periplasmic material that, via the proteins and other molecules they contain, project metabolic function into the environment. While OMV production is widespread in proteobacteria, they have been extensively studied only in pathogens, which inhabit fully hydrated environments. However, many (arguably most) bacterial habitats, such as soil, are only partially hydrated. In the latter, water is characteristically distributed as films on soil particles that are, on average thinner, than are typical OMV (ca. ≤10 nm water film vs. 20 to >200 nm OMV;). Methodology/Principal Findings: We have identified a new bacterial surface structure, termed a "nanopod", that is a conduit for projecting OMV significant distances (e.g., ≥6 µm) from the cell. Electron cryotomography was used to determine nanopod three-dimensional structure, which revealed chains of vesicles within an undulating, tubular element. By using immunoelectron microscopy, proteomics, heterologous expression and mutagenesis, the tubes were determined to be an assembly of a surface layer protein (NpdA), and the interior structures identified as OMV. Specific metabolic function(s) for nanopods produced by Delftia sp. Cs1-4 are not yet known. However, a connection with phenanthrene degradation is a possibility since nanopod formation was induced by growth on phenanthrene. Orthologs of NpdA were identified in three other genera of the Comamonadaceae family, and all were experimentally verified to form nanopods. Conclusions/Significance: Nanopods are new bacterial organelles, and establish a new paradigm in the mechanisms by which bacteria effect long-distance interactions with their environment. Specifically, they create a pathway through which cells can effectively deploy OMV, and the biological activity these transmit, in a diffusion-independent manner. Nanopods would thus allow environmental bacteria to expand their metabolic sphere of influence in a manner previously unknown for these organisms

Climacteric Lowers Plasma Levels of Platelet-Derived Microparticles: A Pilot Study in Pre-versus Postmenopausal Women

Background: Climacteric increases the risk of thrombotic events by alteration of plasmatic coagulation. Up to now, less is known about changes in platelet-(PMP) and endothelial cell-derived microparticles (EMP). Methods: In this prospective study, plasma levels of microparticles (MP) were compared in 21 premenopausal and 19 postmenopausal women. Results: No altered numbers of total MP or EMP were measured within the study groups. However, the plasma values of CD61-exposing MP from platelets/megakaryocytes were higher in premenopausal women (5,364 x 10(6)/l, range 4,384-17,167) as compared to postmenopausal women (3,808 x 10(6)/l, range 2,009-8,850; p = 0.020). This differentiation was also significant for the subgroup of premenopausal women without hormonal contraceptives (5,364 x 10(6)/l, range 4,223-15,916; p = 0.047; n = 15). Furthermore, in premenopausal women, higher plasma levels of PMP exposing CD62P were also present as compared to postmenopausal women (288 x 10(6)/l, range 139-462, vs. 121 x 10(6)/l, range 74-284; p = 0.024). This difference was also true for CD63+ PMP levels (281 x 10(6)/l, range 182-551, vs. 137 x 10(6)/l, range 64-432; p = 0.015). Conclusion: Climacteric lowers the level of PMP but has no impact on the number of EMP in women. These data suggest that PMP and EMP do not play a significant role in enhancing the risk of thrombotic events in healthy, postmenopausal women. Copyright (C) 2012 S. Karger AG, Base

Engaging with community researchers for exposure science: lessons learned from a pesticide biomonitoring study

A major challenge in biomonitoring studies with members of the general public is ensuring their continued involvement throughout the necessary length of the research. The paper presents evidence on the use of community researchers, recruited from local study areas, as a mechanism for ensuring effective recruitment and retention of farmer and resident participants for a pesticides biomonitoring study. The evidence presented suggests that community researchers' abilities to build and sustain trusting relationships with participants enhanced the rigour of the study as a result of their on-the-ground responsiveness and flexibility resulting in data collection beyond targets expected

Limited effect of patient and disease characteristics on compliance with hospital antimicrobial guidelines

Objective: Physicians frequently deviate from guidelines that promote prudent use of antimicrobials. We explored to what extent patient and disease characteristics were associated with compliance with guideline recommendations for three common infections. Methods: In a 1-year prospective observational study, 1,125 antimicrobial prescriptions were analysed for compliance with university hospital guidelines. Results: Compliance varied significantly between and within the groups of infections studied. Compliance was much higher for lower respiratory tract infections (LRTIs; 79%) than for sepsis (53%) and urinary tract infections (UTIs; 40%). Only predisposing illnesses and active malignancies were associated with more compliant prescribing, whereas alcohol/ intravenous drug abuse and serum creatinine levels > 130 mu mol/l were associated with less compliant prescribing. Availability of culture results had no impact on compliance with guidelines for sepsis but was associated with more compliance in UTIs and less in LRTIs. Narrowing initial broad-spectrum antimicrobial therapy to cultured pathogens was seldom practised. Most noncompliant prescribing concerned a too broad spectrum of activity when compared with guideline-recommended therapy. Conclusion: Patient characteristics had only a limited impact on compliant prescribing for a variety of reasons. Physicians seemed to practise defensive prescribing behaviour, favouring treatment success in current patients over loss of effectiveness due to resistance in future patients
