SHERPA-LEAP: a consortial model for the creation and support of academic institutional repositories

Purpose: To introduce SHERPA-LEAP, a model for the consortial development, population and support of eprints repositories. Design/methodology/approach: The organisational and technical structures of the consortium are described, including a brief summary of central and local resource responsibilities. Some positive and negative aspects of a consortial approach to institutional repository development, and of the SHERPA-LEAP model in particular, are identified. Outstanding issues and future plans for the consortium are outlined. Findings: SHERPA-LEAP is found to be succeeding in its aims of developing and supporting eprints repositories within the federal University of London. Some lessons learned from the SHERPA-LEAP approach are identified, but the SHERPA-LEAP consortial model is found to have been mostly beneficial to the participating institutions. In particular, the networking and experience-sharing opportunities which any consortial solution will facilitate are highly valued by the SHERPA-LEAP partners. Value: The case study is intended to help to inform the decision-making of institutions and consortia which are considering consortial solutions to the establishment and maintenance of institutional repositories

Survey of multi-function display and control technology

The NASA orbiter spacecraft incorporates a complex array of systems, displays and controls. The incorporation of discrete dedicated controls into a multi-function display and control system (MFDCS) offers the potential for savings in weight, power, panel space and crew training time. The technology applicable to the development of a MFDCS for orbiter application is surveyed. Technology thought to be applicable presently or in the next five years is highlighted. Areas discussed include display media, data handling and processing, controls and operator interactions and the human factors considerations which are involved in a MFDCS design. Several examples of applicable MFDCS technology are described

Which lipid measurement should we monitor? An analysis of the LIPID study

OBJECTIVES: To evaluate the optimal lipid to measure in monitoring patients, we assessed three factors that influence the choice of monitoring tests: (1) clinical validity; (2) responsiveness to therapy changes and (3) the size of the long-term ‘signal-to-noise’ ratio. DESIGN: Longitudinal analyses of repeated lipid measurement over 5 years. SETTING: Subsidiary analysis of a Long-Term Intervention with Pravastatin in Ischaemic Disease (LIPID) study—a clinical trial in Australia, New Zealand and Finland. PARTICIPANTS: 9014 patients aged 31–75 years with previous acute coronary syndromes. INTERVENTIONS: Patients were randomly assigned to 40 mg daily pravastatin or placebo. PRIMARY AND SECONDARY OUTCOME MEASURES: We used data on serial lipid measurements—at randomisation, 6 months and 12 months, and then annually to 5 years—of total cholesterol; low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol and their ratios; triglycerides; and apolipoproteins A and B and their ratio and their ability to predict coronary events. RESULTS: All the lipid measures were statistically significantly associated with future coronary events, but the associations between each of the three ratio measures (total or LDL cholesterol to HDL cholesterol, and apolipoprotein B to apolipoprotein A1) and the time to a coronary event were better than those for any of the single lipid measures. The two cholesterol ratios also ranked highly for the long-term signal-to-noise ratios. However, LDL cholesterol and non-HDL cholesterol showed the most responsiveness to treatment change. CONCLUSIONS: Lipid monitoring is increasingly common, but current guidelines vary. No single measure was best on all three criteria. Total cholesterol did not rank highly on any single criterion. However, measurements based on cholesterol subfractions—non-HDL cholesterol (total cholesterol minus HDL cholesterol) and the two ratios—appeared superior to total cholesterol or any of the apolipoprotein options. Guidelines should consider using non-HDL cholesterol or a ratio measure for initial treatment decisions and subsequent monitoring

Is penicillin allergy de-labelling about to find its place in UK antimicrobial stewardship strategy?

Penicillin allergy records are common, often incorrect, limit antibiotic treatment options and associated with patient and health system harm. The large numbers of patients with penicillin allergy records and the paucity of allergists have led researchers to explore non-allergist delivered assessment of penicillin allergy records and removal of those inconsistent with allergy (called de-labelling). A recent systematic review and meta-analysis of the literature concludes non-allergist delivery of penicillin allergy de-labelling to be safe and effective. Several countries outside Europe have endorsed non-allergist de-labelling and produced national guidelines and toolkits for de-labelling, but until recently the UK lacked such guidance. In September 2022 the British Society of Allergy and Clinical Immunology (BSACI) produced their guidelines endorsing non-allergist delivered penicillin allergy de-labelling. These BSACI guidelines, coupled with the ongoing NIHR funded penicillin allergy de-labelling studies, will enable this important patient safety and antimicrobial stewardship intervention to become standard of care for NHS patients

TgCDPK3 Regulates Calcium-Dependent Egress of Toxoplasma gondii from Host Cells

The phylum Apicomplexa comprises a group of obligate intracellular parasites of broad medical and agricultural significance, including Toxoplasma gondii and the malaria-causing Plasmodium spp. Key to their parasitic lifestyle is the need to egress from an infected cell, actively move through tissue, and reinvade another cell, thus perpetuating infection. Ca(2+)-mediated signaling events modulate key steps required for host cell egress, invasion and motility, including secretion of microneme organelles and activation of the force-generating actomyosin-based motor. Here we show that a plant-like Calcium-Dependent Protein Kinase (CDPK) in T. gondii, TgCDPK3, which localizes to the inner side of the plasma membrane, is not essential to the parasite but is required for optimal in vitro growth. We demonstrate that TgCDPK3, the orthologue of Plasmodium PfCDPK1, regulates Ca(2+) ionophore- and DTT-induced host cell egress, but not motility or invasion. Furthermore, we show that targeting to the inner side of the plasma membrane by dual acylation is required for its activity. Interestingly, TgCDPK3 regulates microneme secretion when parasites are intracellular but not extracellular. Indeed, the requirement for TgCDPK3 is most likely determined by the high K(+) concentration of the host cell. Our results therefore suggest that TgCDPK3's role differs from that previously hypothesized, and rather support a model where this kinase plays a role in rapidly responding to Ca(2+) signaling in specific ionic environments to upregulate multiple processes required for gliding motility.This work was supported by the National Health and Medical Research Council (NHMRC) Project Grant APP1025598.

Evaluating the impact of air pollution on the incidence of out-of-hospital cardiac arrest in the Perth Metropolitan Region: 2000–2010

Background: Out-of-hospital cardiac arrest (OHCA) remains a major public health issue. Several studies have found that an increased level of ambient particulate matter (PM) smaller than 2.5 microns (PM2.5) is associated with an increased risk of OHCA. We investigated the relationship between air pollution levels and the incidence of OHCA in Perth, Western Australia.Methods: We linked St John Ambulance OHCA data of presumed cardiac aetiology with Perth air pollution data from seven monitors which recorded hourly levels of PM smaller than 2.5 and 10 microns (PM2.5/PM10), carbon monoxide (CO), sulfur dioxide (SO2), nitrogen dioxide (NO2) and ozone (O3). We used a case-crossover design to estimate the strength of association between ambient air pollution levels and risk of OHCA.Methods: We linked St John Ambulance OHCA data of presumed cardiac aetiology with Perth air pollution data from seven monitors which recorded hourly levels of PM smaller than 2.5 and 10 microns (PM2.5/PM10), carbon monoxide (CO), sulfur dioxide (SO2), nitrogen dioxide (NO2) and ozone (O3).
