Pressure Ulcer and Wounds Reporting in NHS Hospitals in England Part 1: Audit of Monitoring Systems

Internationally, health-care systems have attempted to assess the scale of and demonstrate improvement in patient harms. Pressure ulcer (PU) monitoring systems have been introduced across NHS in-patient facilities in England, including the Safety Thermometer (STh) (prevalence), Incident Reporting Systems (IRS) and the Strategic Executive Information System (STEIS) for serious incidents. This is the first of two related papers considering PU monitoring systems across NHS in-patient facilities in England and focusses on a Wound Audit (PUWA) to assess the accuracy of these systems. Part 2 of this work and recommendations are reported pp *-*. The PUWA was undertaken in line with ‘gold-standard’ PU prevalence methods in a stratified random sample of NHS Trusts; 24/34(72.7%) invited NHS Trusts participated, from which 121 randomly selected wards and 2239 patients agreed to participate. Prevalence of existing PUs: The PUWA identified 160(7.1%) patients with an existing PU, compared to 105(4.7%) on STh. STh had a weighted sensitivity of 48.2%(95%CI 35.4%-56.7%) and weighted specificity of 99.0%(95%CI 98.99%-99.01%). Existing/healed PUs: The PUWA identified 189(8.4%) patients with an existing/healed PU compared to 135(6.0%) on IRS. IRS had an unweighted sensitivity of 53.4%(95%CI 46.3% to 60.4%) and unweighted specificity of 98.3% (95%CI 97.7% to 98.8%). 83 patients had one or more potentially serious PU on PUWA and 8(9.6%) of these patients were reported on STEIS. The results identified high levels of under-reporting for all systems and highlighted data capture challenges, including the use of clinical staff to inform national monitoring systems and the completeness of clinical records for PUs

Ridinilazole: A novel therapy for Clostridium difficile infection

Clostridium difficile infection (CDI) is the leading cause of infectious healthcare-associated diarrhoea. Recurrent CDI increases disease morbidity and mortality, posing a high burden to patients and a growing economic burden to the healthcare system. Thus, there exists a significant unmet and increasing medical need for new therapies for CDI. This review aims to provide a concise summary of CDI in general and a specific update on ridinilazole (formerly SMT19969), a novel antibacterial currently under development for the treatment of CDI. Owing to its highly targeted spectrum of activity and ability to spare the normal gut microbiota, ridinilazole provides significant advantages over metronidazole and vancomycin, the mainstay antibiotics for CDI. Ridinilazole is bactericidal against . C. difficile and exhibits a prolonged post-antibiotic effect. Furthermore, treatment with ridinilazole results in decreased toxin production. A phase 1 trial demonstrated that oral ridinilazole is well tolerated and specifically targets clostridia whilst sparing other faecal bacteria. Phase 2 and 3 trials will hopefully further our understanding of the clinical utility of ridinilazole for the treatment of CDI

Magnetic Field Induced Quantum Spin Liquid in the Two Coupled Trillium Lattices of K2 Ni2 (SO4)3

Quantum spin liquids are exotic states of matter that form when strongly frustrated magnetic interactions induce a highly entangled quantum paramagnet far below the energy scale of the magnetic interactions. Three-dimensional cases are especially challenging due to the significant reduction of the influence of quantum fluctuations. Here, we report the magnetic characterization of K2Ni2(SO4)3 forming a three-dimensional network of Ni2+ spins. Using density functional theory calculations, we show that this network consists of two interconnected spin-1 trillium lattices. In the absence of a magnetic field, magnetization, specific heat, neutron scattering, and muon spin relaxation experiments demonstrate a highly correlated and dynamic state, coexisting with a peculiar, very small static component exhibiting a strongly renormalized moment. A magnetic field B≳4  T diminishes the ordered component and drives the system into a pure quantum spin liquid state. This shows that a system of interconnected S=1 trillium lattices exhibits a significantly elevated level of geometrical frustration

Theatre and drama education and populism : the ensemble ‘family’ as a space for dialogic empathy and civic care

This article, understanding populism as an essentially undemocratic ideology, argues that the pro‐social theatre education approach of ensemble pedagogy can offer a model of educational practice which counters these anti‐democratic rhetorics by creating a shared space for the enactment of empathetic discourse. Via an ethnography of the UK Shakespeare Schools Foundation festival project, the notion of the theatre education ensemble ‘family’ as a model of civic caring is offered as an alternative, feminist ‘care perspective’ on civic and political rhetorics, in contrast to the patriarchal ‘justice perspectives’ which facilitate the reductive anti‐democratic rhetorics of populism. Thus, this article concludes that ensemble approaches to theatre education, viewed through this feminist pedagogy lens, hold rich potential for developing learners’ capacity to resist populism and act in socially hopeful ways

Leaf metabolic traits reveal hidden dimensions of plant form and function

International audienceThe metabolome is the biochemical basis of plant form and function, but we know little about its macroecological variation across the plant kingdom. Here, we used the plant functional trait concept to interpret leaf metabolome variation among 457 tropical and 339 temperate plant species. Distilling metabolite chemistry into five metabolic functional traits reveals that plants vary on two major axes of leaf metabolic specialization—a leaf chemical defense spectrum and an expression of leaf longevity. Axes are similar for tropical and temperate species, with many trait combinations being viable. However, metabolic traits vary orthogonally to life-history strategies described by widely used functional traits. The metabolome thus expands the functional trait concept by providing additional axes of metabolic specialization for examining plant form and function

Search for displaced vertices arising from decays of new heavy particles in 7 TeV pp collisions at ATLAS

We present the results of a search for new, heavy particles that decay at a significant distance from their production point into a final state containing charged hadrons in association with a high-momentum muon. The search is conducted in a pp-collision data sample with a center-of-mass energy of 7 TeV and an integrated luminosity of 33 pb^-1 collected in 2010 by the ATLAS detector operating at the Large Hadron Collider. Production of such particles is expected in various scenarios of physics beyond the standard model. We observe no signal and place limits on the production cross-section of supersymmetric particles in an R-parity-violating scenario as a function of the neutralino lifetime. Limits are presented for different squark and neutralino masses, enabling extension of the limits to a variety of other models.Comment: 8 pages plus author list (20 pages total), 8 figures, 1 table, final version to appear in Physics Letters
