    On July 16th 2016 the UNILAC and SIS18 proton performance has been measured. Due to scheduled maintenance works of the UNILAC's rf-system, the post-stripper energy was restricted to 5.9~MeV and accordingly the beam quality suffered considerably from the interruption of the periodic focusing system. This limitation will not be any longer in future beam times. Six single-gap resonators were used for acceleration to 10.7~MeV. After an optimization of the multi-turn injection 1.21011\pmb{1.2\cdot10^{11}} protons were extracted form the SIS18

    An integrated general practice and pharmacy-based intervention to promote the use of appropriate preventive medications among individuals at high cardiovascular disease risk: protocol for a cluster randomized controlled trial

    Background: Cardiovascular diseases (CVD) are responsible for significant morbidity, premature mortality, and economic burden. Despite established evidence that supports the use of preventive medications among patients at high CVD risk, treatment gaps remain. Building on prior evidence and a theoretical framework, a complex intervention has been designed to address these gaps among high-risk, under-treated patients in the Australian primary care setting. This intervention comprises a general practice quality improvement tool incorporating clinical decision support and audit/feedback capabilities; availability of a range of CVD polypills (fixed-dose combinations of two blood pressure lowering agents, a statin ± aspirin) for prescription when appropriate; and access to a pharmacy-based program to support long-term medication adherence and lifestyle modification. Methods: Following a systematic development process, the intervention will be evaluated in a pragmatic cluster randomized controlled trial including 70 general practices for a median period of 18 months. The 35 general practices in the intervention group will work with a nominated partner pharmacy, whereas those in the control group will provide usual care without access to the intervention tools. The primary outcome is the proportion of patients at high CVD risk who were inadequately treated at baseline who achieve target blood pressure (BP) and low-density lipoprotein cholesterol (LDL-C) levels at the study end. The outcomes will be analyzed using data from electronic medical records, utilizing a validated extraction tool. Detailed process and economic evaluations will also be performed. Discussion: The study intends to establish evidence about an intervention that combines technological innovation with team collaboration between patients, pharmacists, and general practitioners (GPs) for CVD prevention.

    Objective: To determine the cost-effectiveness of complete revascularisation at index admission compared to infarct-related artery (IRA) treatment only, in patients with multi-vessel disease undergoing Primary percutaneous coronary intervention (P-PCI) for ST-segment elevation Myocardial Infarction (STEMI). Methods: Economic evaluation of a multi-centre randomised trial comparing complete revascularisation at index admission to IRA-only P-PCI in patients with multi-vessel disease (12 month follow-up). Overall hospital costs (costs for P-PCI procedure(s), hospital stay and any subsequent readmissions) were estimated. Outcomes were major adverse cardiac events (MACE, a composite of all-cause death, recurrent myocardial infarction, heart failure, and ischemia-driven revascularisation) and quality-adjusted life years (QALYs) derived from the EQ-5D-3L. Multiple imputation was undertaken. The mean incremental cost and effects, with associated 95% confidence intervals (95%CI), the incremental cost-effectiveness ratio (ICER) and the cost-effectiveness acceptability curve (CEAC) were estimated. Results: Based on 296 patients, the mean incremental overall hospital cost for complete revascularisation was estimated to be –£215.96 (–£1,390.20 to £958.29), compared to IRA-only, with a per-patient mean reduction in MACE events of 0.170 (0.044 to 0.296) and a QALY gain of 0.011 (-0.019 to 0.041). According to the CEAC, the probability of complete revascularisation being cost-effective was estimated to be 72.0% at willingness to pay of £20,000 per QALY. Conclusions: Complete revascularisation at index admission was estimated to be more effective (in terms of MACE and QALYs) and cost-effective (overall costs were estimated to be lower and complete revascularisation thereby dominated IRA-only). There was, however, some uncertainty associated with this decision

    Telepsychiatry During the COVID-19 Pandemic: Development of a Protocol for Telemental Health Care

    Get PDF
    Background: The rapid spread of the Coronavirus disease 2019 (COVID-19) has forced most countries to take drastic public health measures, including the closure of most mental health outpatient services and some inpatient units. This has suddenly created the need to adapt and expand telepsychiatry care across the world. However, not all health care services might be ready to cope with this public health demand. The present study was set to create a practical and clinically useful protocol for telemental health care to be applied in the context of the current COVID-19 pandemic. Methods: A panel of psychiatrists from 15 different countries covering all World Health Organization (WHO) regions was convened. The panel used a combination of reactive Delphi technique and consensus development conference strategies to develop a protocol for the provision of telemental health care during the COVID-19 pandemic. Results: The proposed protocol describes a semi-structured initial assessment and a series of potential interventions matching mild, moderate, or high-intensity needs of target populations. Conclusions: Telemedicine has become a pivotal tool in the task of ensuring the continuous provision of mental health care for the population, and the outlined protocol can assist with this task. The strength of this protocol lies in its practicality, clinical usefulness, and wide transferability, resulting from the diversity of the consensus group that developed it. Developed by psychiatrists from around the globe, the proposed protocol may prove helpful for many clinical and cultural contexts, assisting mental health care providers worldwide. © Copyright © 2020 Ramalho, Adiukwu, Gashi Bytyçi, El Hayek, Gonzalez-Diaz, Larnaout, Grandinetti, Nofal, Pereira-Sanchez, Pinto da Costa, Ransing, Teixeira, Shalbafan, Soler-Vidal, Syarif and Orsolini

    Infectious disease outbreak related stigma and discrimination during the COVID-19 pandemic: Drivers, facilitators, manifestations, and outcomes across the world

    Get PDF
    Being part of a social minority (e.g. migrants, people of color or Asian descent in Western countries) is not itself a risk factor for contracting Coronavirus disease-2019 (COVID-19). However, certain groups of people across the world are being targeted by COVID-19 related stigma (COS) and discrimination, which constitutes a growing concern (Bagcchi, 2020). There is an urgent need to better understand it, as it may pose a barrier for accessing testing and health care and for maintaining treatment adherence (Stangl et al., 2019). It is very likely that COS is the consequence of multiple socio-ecological drivers (e.g., fear, misinformation) and facilitators (e.g., racism, poverty) (Logie, 2020). In this letter, we attempt to explore COS related factors based on the real-life experiences of a group of psychiatrists from thirteen countries using the health stigma and discrimination framework (HSDF) (Stangl et al., 2019). We categorized these experiences as per the process domains (such as drivers, facilitators); and these process domains along with examples/responses are depicted in Fig. (1)

    COVID-19 mental health care toolkit: An international collaborative effort by Early Career Psychiatrists section

    Get PDF
    The collaborative effort of an international research team from the Early Career Psychiatrists section of the World Psychiatry Association has brought about an easy-to-use, quick and stepwise mental health care toolkit for the identification and appropriate referral of those in need of mental health care during the pandemic. This simple guide can be applied in the general outpatient setting and is catered for all healthcare professionals, regardless of their expertise within the mental health field with minimal training. It is our hope that by incorporating this toolkit into our daily clinical care during the pandemic for high-risk patients and patients with non-specific complaints, we will be able to bridge the mental health gap present in our society. © 2020 Author(s) (or their employer(s)) 2020

    Clinical utility of remote platelet function measurement using P-selectin: assessment of aspirin, clopidogrel, and prasugrel and bleeding disorders

    Get PDF
    Vascular diseases such as myocardial infarction and ischemic stroke are associated with increased platelet function whilst the risk of recurrence is reduced by antiplatelet agents such as aspirin, clopidogrel, and prasugrel. However, some patients exhibit high platelet reactivity, especially with clopidogrel. Existing platelet function tests may not be ideal in that they can be expensive, are often time consuming, and measurements must be made near to the patient and within a few hours of blood collection. Platelet activation leads to translocation of P-selectin from alpha-granules to the cell surface. Following activation with arachidonic acid (which is blocked by aspirin) or adenosine diphosphate (inhibited by clopidogrel) and fixation, samples may be stored or posted to a laboratory performing flow cytometric quantification of platelet P-selectin expression. Acute myocardial infarction and ischemic stroke are associated with high platelet reactivity on clopidogrel in 6–58% of patients when assessed with P-selectin expression, and high reactivity was associated with an increased risk of recurrence after myocardial infarction. Use of P-selectin expression tests may also be of relevance to surgical and veterinary practice and the diagnosis of mild bleeding disorders. The present review explores this topic in further detail
