An mHealth intervention to improve nurses’ atrial fibrillation and anticoagulation knowledge and practice: the EVICOAG study
© The European Society of Cardiology 2018. Background: There is a need to improve cardiovascular nurses’ knowledge and practices related to stroke prevention, atrial fibrillation and anticoagulation therapy. Aims: The aim of this study was to evaluate the efficacy of EVICOAG – a novel mHealth, smartphone-based, spaced-learning intervention on nurses’ knowledge of atrial fibrillation and anticoagulation. Methods: Nurses employed in four clinical specialties (neuroscience, stroke, rehabilitation, cardiology) across three hospitals were invited to participate. In this quasi-experimental study, 12 case-based atrial fibrillation and anticoagulation learning scenarios (hosted by an mHealth platform) were delivered to participants’ smartphones over a 6-week period (July–December 2016) using a spaced timing algorithm. Electronic surveys to assess awareness and knowledge were administered pre (T1) and post (T2) intervention. Results: From 74 participants recruited to T1, 40 completed T2. There was a 54% mean improvement in knowledge levels post-intervention. The largest improvement was achieved in domains related to medication interaction and stroke and bleeding risk assessment. Post-intervention, those who completed T2 were significantly more likely to use CHA 2 DS 2 -VASc (2.5% vs. 37.5%) and HAS-BLED (2.5% vs. 35%) tools to assess stroke and bleeding risk, respectively (P<0.01). Conclusion: The EVICOAG intervention improved nurses’ knowledge of atrial fibrillation and anticoagulation, and influenced their uptake and use of stroke and bleeding risk assessment tools in clinical practice. Future research should focus on whether a similar intervention might improve patient-centred outcomes such as patients’ knowledge of their condition and therapies, medication adherence, time in the therapeutic range and quality of life
A cluster-randomized controlled trial of a computerized antithrombotic risk assessment tool to optimize stroke prevention in general practice: a study protocol
Controllable synthesis, XPS investigation and magnetic property of multiferroic BiMn2O5 system: The role of neodyme doping
In this work, a novel series of multiferroic materials BiMn2O5 doped by Neodyme has been prepared by a sol-gel
method at low temperature. The crystallographic studies using X-ray diffraction and Rietveld Refinement
techniques showed the formation of single-phase samples for all compositions, crystallizing in a mullite-type
orthorhombic perovskite structure, space group Pbam (Z=4). The SEM techniques confirmed the formation of
single-phase materials with excellent mapping distribution. Raman and infrared spectroscopic measurements
were performed and combined with lattice dynamics simulations to describe the room-temperature vibrational
properties of all samples. The X-ray Photoelectron Spectroscopy (XPS) were measured in the energy range of
0–1400 eV at room temperature. The Fermi level EF was defined with the accuracy of 0.127, 0.32 and 0.48 eV for
BiMn2O5, Bi0.9Nd0.1Mn2O5 and Bi0.8Nd0.2Mn2O5 respectively. The X-ray photoelectron spectroscopy shows the
existence of Mn4+ state. Magnetic measurements indicate Neél temperature TN at 31, 40 and 61 K for BiMn2O5,
Bi0.9Nd0.1Mn2O5 and Bi0.8Nd0.2Mn2O5 respectively

Pharmacists in general practice: a qualitative interview case study of stakeholders’ experiences in a West London GP Federation
Background
Increased patient demand for healthcare services coupled with a shortage of general practitioners necessitates changes in professional roles and service delivery. In 2016, NHS England began a three year pilot study of pharmacists in general practice, however, this is not an entirely new initiative. There is limited, current, evidence-based, UK research to inform the pilot so studies of pre-existing services must suffice until findings from a formal national evaluation are available.
Methods
The aim of this exploratory, descriptive interview study was to explore the experiences of stakeholders in eight general practices in the Ealing GP Federation, West London, where pharmacy services have been provided for several years. Forty-seven participants, including pharmacy team members (pre-registration and clinical pharmacists, independent prescribers and pharmacy technicians), general practitioners, patients, practice managers, practice nurses and receptionists took part in semi-structured, audio-recorded qualitative interviews which were transcribed verbatim, coded and analysed thematically to extract the issues raised by participants and the practicalities of providing pharmacy services in general practice.
Results
Findings are reported under the themes of Complementarity (incorporating roles, skills, education and workloads); Integration (incorporating relationships, trust and communication) and Practicalities (incorporating location and space, access, and costs). Participants reported the need for time to develop and understand the various roles, develop communication processes and build inter-professional trust. Once these were established, however, experiences were positive and included decreased workloads, increased patient safety, improved job satisfaction, improved patient relationships, and enhanced cost savings. Areas for improvement included patients’ awareness of services; pharmacists’ training; and regular, onsite access for practice staff to the pharmacy team.
Conclusions
Recommendations are made for the development of clear role definitions, identification of training needs, dedication of time for team building, production of educational materials for practice staff members and patients, and provision of on-site, full-time pharmacy services. Future work should focus on evaluation of various models of employing pharmacy teams in general practice; integration of pharmacists and pharmacy technicians into multidisciplinary general practice teams; relationships between local community pharmacy and general practice personnel and patients’ service and information needs. A formal national evaluation of the pilot scheme is overdue

Altered Composition of Liver Proteasome Assemblies Contributes to Enhanced Proteasome Activity in the Exceptionally Long-Lived Naked Mole-Rat
The longest-lived rodent, the naked mole-rat (Bathyergidae; Heterocephalus glaber), maintains robust health for at least 75% of its 32 year lifespan, suggesting that the decline in genomic integrity or protein homeostasis routinely observed during aging, is either attenuated or delayed in this extraordinarily long-lived species. The ubiquitin proteasome system (UPS) plays an integral role in protein homeostasis by degrading oxidatively-damaged and misfolded proteins. In this study, we examined proteasome activity in naked mole-rats and mice in whole liver lysates as well as three subcellular fractions to probe the mechanisms behind the apparently enhanced effectiveness of UPS. We found that when compared with mouse samples, naked mole-rats had significantly higher chymotrypsin-like (ChT-L) activity and a two-fold increase in trypsin-like (T-L) in both whole lysates as well as cytosolic fractions. Native gel electrophoresis of the whole tissue lysates showed that the 20S proteasome was more active in the longer-lived species and that 26S proteasome was both more active and more populous. Western blot analyses revealed that both 19S subunits and immunoproteasome catalytic subunits are present in greater amounts in the naked mole-rat suggesting that the observed higher specific activity may be due to the greater proportion of immunoproteasomes in livers of healthy young adults. It thus appears that proteasomes in this species are primed for the efficient removal of stress-damaged proteins. Further characterization of the naked mole-rat proteasome and its regulation could lead to important insights on how the cells in these animals handle increased stress and protein damage to maintain a longer health in their tissues and ultimately a longer life
