Abstract
Diabetic ketoacidosis (DKA) is a common cause for admission in Emergency Department. Its treatment is well defined. Nevertheless, in some cases, type I diabetes combines with auto-immune polyendocrine syndrome, which can carry life-threatening consequences. Here we report the case of a young man with inaugural DKA who exhibited ventricular fibrillation and cardiac arrest due to significant hypokalaemia, following undiagnosed thyrotoxicosis with periodic paralysis.

Abstract
BACKGROUND Experimental studies suggest that morphine may protect the myocardium against ischemia-reperfusion injury by activating salvage kinase pathways. The objective of this two-center, randomized, double-blind, controlled trial was to assess potential cardioprotective effects of intra-coronary morphine in patients with ST-segment elevation myocardial infarction (STEMI) referred for primary percutaneous intervention. METHODS Ninety-one patients with STEMI were randomly assigned to intracoronary morphine (1 mg) or placebo at reperfusion of the culprit coronary artery. The primary endpoint was infarct size/left ventricular mass ratio assessed by magnetic resonance imaging on day 3-5. Secondary endpoints included the areas under the curve (AUC) for troponin T and creatine kinase over three days, left ventricular ejection fraction assessed by echocardiography on days 1 and 6, and clinical outcomes. RESULTS Infarct size/left ventricular mass ratio was not significantly reduced by intracoronary morphine compared to placebo (27.2% ± 15.0% vs. 30.5% ± 10.6%, respectively, p = 0.28). Troponin T and creatine kinase AUCs were similar in the two groups. Morphine did not improve left ventricular ejection fraction on day 1 (49.7 ± 10.3% vs. 49.3 ± 9.3% with placebo, p = 0.84) or day 6 (48.5 ± 10.2% vs. 49.0 ± 8.5% with placebo, p = 0.86). The number of major adverse cardiac events, including stent thrombosis, during the one-year follow-up was similar in the two groups. CONCLUSIONS Intracoronary morphine at reperfusion did not significantly reduce infarct size or improve left ventricular systolic function in patients with STEMI. Presence of comorbidities in some patients may contribute to explain these results. TRIAL REGISTRATION ClinicalTrials.gov, NCT01186445 (date of registration: August 23, 2010).

Combining VITEK ® 2 with colistin agar dilution screening assist timely reporting of colistin susceptibility. Clin Microbiol Infect 2018; 25:711-716.

Abstract
OBJECTIVES The rise in carbapenem resistance among Gram-negative bacteria has renewed interest in colistin. Recently, the EUCAST-CLSI Polymyxin Breakpoints Working Group declared that broth microdilution (BMD) is the only valid method for colistin susceptibility testing. BMD is not easily incorporated into the routine work of clinical laboratories, and usually this test is incorporated serially, resulting in delayed susceptibility reporting. We tested a strategy of combining VITEK® 2 with a 2 μg/mL colistin agar dilution (VITEK® 2/AD) screening plate to improve performance and time to reporting of colistin susceptibility. METHODS Colistin susceptibility for 364 clinical isolates was determined by VITEK® 2/AD and compared with the reference standard BMD according to the ISO 20776-1:2007 and CLSI guidelines. The EUCAST colistin susceptibility breakpoint of ≤2 μg/mL was used. Escherichia coli NCTC 13846 served as quality control strain. Agreement, very major error (VME) and major error rates were determined using ISO 20776-2:2007. RESULTS The VME rate for VITEK® 2 alone was 30.6% (15/49, 95% CI 18.3-45.4%), and was reduced to 10.2% (5/49, 95% CI 3.4-22.2%) using the VITEK® 2/AD combined testing. The combined testing had categorical agreement with BMD of 97% (354/364, 95% CI 95.0-98.7%), and a major error (ME) rate of 1.6% (5/315, 95% CI 0.5-3.7%). Using the combined testing, even against challenging strains, 349 (95.8%, 95% CI 93.3-97.7%) colistin susceptibility results could be reported, and only 15 isolates required further analysis by BMD. DISCUSSION Our method is simple to apply and allows rapid reporting of colistin susceptibility.

Abstract
The ^{36}Ar(n,γ)^{37}Ar (t_{1/2}=35 d) and ^{38}Ar(n,γ)^{39}Ar (269 yr) reactions were studied for the first time with a quasi-Maxwellian (kT∼47 keV) neutron flux for Maxwellian average cross section (MACS) measurements at stellar energies. Gas samples were irradiated at the high-intensity Soreq applied research accelerator facility-liquid-lithium target neutron source and the ^{37}Ar/^{36}Ar and ^{39}Ar/^{38}Ar ratios in the activated samples were determined by accelerator mass spectrometry at the ATLAS facility (Argonne National Laboratory). The ^{37}Ar activity was also measured by low-level counting at the University of Bern. Experimental MACS of ^{36}Ar and ^{38}Ar, corrected to the standard 30 keV thermal energy, are 1.9(3) and 1.3(2) mb, respectively, differing from the theoretical and evaluated values published to date by up to an order of magnitude. The neutron-capture cross sections of ^{36,38}Ar are relevant to the stellar nucleosynthesis of light neutron-rich nuclides; the two experimental values are shown to affect the calculated mass fraction of nuclides in the region A=36-48 during the weak s process. The new production cross sections have implications also for the use of ^{37}Ar and ^{39}Ar as environmental tracers in the atmosphere and hydrosphere.

Abstract
BACKGROUND AND AIM The European Society of Clinical Microbiology and Infectious Diseases (ESCMID) aims to further develop its role in international medical and scientific guidance in the field of Clinical Microbiology and Infectious Diseases, where many types of guidance documents exist. The ESCMID Executive Committee and the Clinical Microbiology and Infection (CMI) editorial board wish to clarify the terminology and format to be used in ESCMID guidance documents submitted for publication in CMI, and to highlight the principles behind ESCMID guidance documents. TYPES OF GUIDANCE DOCUMENTS There are five types of ESCMID guidance documents: White Papers, Clinical Practice Guidelines, Consensus Statements, State-of-the-Science Statements, and Position Papers. They differ in scope, methods of development, drafting group composition and preferred publication format. Guidance documents can be proposed, developed and published by ESCMID Study Groups, Committees and individual members; often, other scientific societies are involved. The full disclosure of potential conflicts of interest of all drafting group members is a requirement. FINAL REMARKS Guidance documents constitute a common cultural and scientific background to people in the same and related professions. Also, they are an important educational and training tool. Developing a guidance document is a scientific endeavour, where a sound and transparent development process is needed, requiring multidisciplinary and personal skills.

Abstract
BACKGROUND Antimicrobials are among the most frequently prescribed drugs in long-term care facilities (LTCFs). Implementation of antimicrobial stewardship programmes (ASPs) is often challenging because of scarce data in this setting. OBJECTIVES This narrative review aimed to provide data about antibiotic consumption in LTCFs and the need, implementation, and organization of ASPs in this setting. SOURCE PubMed was searched for studies assessing antimicrobial consumption and implementation of ASPs in LTCFs. The search was restricted to articles published in English in the last 10 years. Experts belonging to the ESCMID Study Group for Infections in the Elderly (ESGIE) reviewed the selected studies and evaluated the studies on ASPs according to the GRADE approach. Moreover, the quality of reporting has been assessed according to TREND and CONSORT checklists for quasi-experimental and cluster randomized clinical trials (cRCT), respectively. CONTENT Data on antibiotic consumption in LTCFs show great variability in LTCFs across and within countries. Reasons for this variability are difficult to analyse because of the differences in the types of LTCFs, their organization, and the population cared-for in the different LTCFs. However, studies show that the use of antibiotics among elderly patients in LTCFs, especially in cases of asymptomatic bacteriuria and influenza-like syndromes, is often inappropriate. High-quality cRCTs and low to moderate quality quasi-experimental studies show that educational interventions direct at nurse and physicians are effective in reducing unnecessary antibiotic prescriptions. IMPLICATIONS There is an urgent need for ASPs tailored for LTCFs. Multifaceted organized educational interventions, involving both clinicians and nursing staff, should be advocated and require institutional intervention by health authorities. Future studies assessing the impact of well-defined ASPs in LTCFs should produce compelling evidence in this setting.

Abstract
BACKGROUND Transition from distinct Child and Adolescent Mental Health (CAMHS) to Adult Mental Health Services (AMHS) is beset with multitude of problems affecting continuity of care for young people with mental health needs. Transition-related discontinuity of care is a major health, socioeconomic and societal challenge globally. The overall aim of the Managing the Link and Strengthening Transition from Child to Adult Mental Health Care in Europe (MILESTONE) project (2014-19) is to improve transition from CAMHS to AMHS in diverse healthcare settings across Europe. MILESTONE focuses on current service provision in Europe, new transition-related measures, long term outcomes of young people leaving CAMHS, improving transitional care through 'managed transition', ethics of transitioning and the training of health care professionals. METHODS Data will be collected via systematic literature reviews, pan-European surveys, and focus groups with service providers, users and carers, and members of youth advocacy and mental health advocacy groups. A prospective cohort study will be conducted with a nested cluster randomised controlled trial in eight European Union (EU) countries (Belgium, Croatia, France, Germany, Ireland, Italy, Netherlands, UK) involving over 1000 CAMHS users, their carers, and clinicians. DISCUSSION Improving transitional care can facilitate not only recovery but also mental health promotion and mental illness prevention for young people. MILESTONE will provide evidence of the organisational structures and processes influencing transition at the service interface across differing healthcare models in Europe and longitudinal outcomes for young people leaving CAMHS, solutions for improving transitional care in a cost-effective manner, training modules for clinicians, and commissioning and policy guidelines for service providers and policy makers.

Abstract
AIM The aim of this case series was to report the use of 8% topical capsaicin patch (marketed under the trade name Qutenza®) a in the management of refractory neuropathic pain (NP) in adult patients with type 1 neurofibromatosis (NF1). METHODS Capsaicin has been suggested for NF1 patients suffering from refractory peripheral NP despite several years of analgesic treatments. The patch was applied for 60 minutes on the painful area, with tolerability control (blood pressure, intensity of pain and dermal reaction). The evaluation was done at the beginning of treatment and during the 2 months following the first treatment (phone calls at weeks 1, 2, 4 and 8). The primary efficacy criterion was the response rate: a patient was considered to be responding if he or she reported an average relief ≥30% at the time of the follow-up calls. The secondary criteria were: interference scores (QCD), Patient Global Impression of Change (PGIC) and overall treatment satisfaction, self-reported by the patient. RESULTS Eight patients (5 females/3 males, 41.8 ± 8.2 years of age) received a first treatment with capsaicin. Patients had pre-existing pain for 6.6 years (±6.0) and were currently receiving an average of 6.1 (±3.9) different analgesics. The response rate was 37.5%. The three responders felt globally improved and satisfied, with the improvement in overall condition as interference scores decreased. Apart from the expected local reactions, the treatment was not accompanied by systemic side effects. CONCLUSIONS As suggested in this case series, capsaicin provided pain relief in certain NF1 patients with resistant NP. The response rate is that expected in multi-line refractory NP. A significant benefit on the overall condition of some patients was observed. In addition, this topical treatment is administered every 3 months without systemic effects. This study is limited by the small number of patients, but was intended to describe a new and well tolerated alternative treatment.

Abstract
The duration of safe heart preservation must be improved. Using a heterotopic heart transplantation model, we compared in vivo the recovery of rabbits hearts preserved with a K+ Lactobionate based fluid (UW: University of Wisconsin solution) or with a Na+Lactobionate based fluid. In the “preservation” group, hearts were cold stored (4°C) for 6 hours with UW (n=9) or Na+Lactobionate solution (n=9). In the “transplantation” group, cold storage was followed by 3 hours of reperfusion (UW: n=8, Na+Lactobionate solution: n=7). Functional recovery, adenine nucleotide pool, circulating blood cardiac enzymes, circulating blood and tissue malondialdehyde (MDA) were measured. Left ventricular enddiastolic and developed pressures at different preload levels were better after preservation with UW than with Na+Lactobionate solution (p<0.05). Also with UW, adenosine diphosphate and total adenine nucleotide content were significantly higher than with Na+Lactobionate solution (p<0.05) whereas adenosine triphosphate, monophosphate and energy charges were similar. Cardiac enzymes and tissue MDA were similar with UW and Na+Lactobionate solution. In circulating blood, MDA was not detected. These results enhance the superiority of UW solution over a Na+Lactobionate based solution for long term heart preservation.

Abstract
Summary
Objectives: Selection of empirical antibiotic therapy relies on knowledge of the in vitro susceptibilities of potential pathogens to antibiotics. In this paper the limitations of this knowledge are outlined and a method that can reduce some of the problems is developed.
Methods: We propose hierarchical Dirichlet learning for estimation of pathogen susceptibilities to antibiotics, using data from a group of similar pathogens in a bacteremia database.
Results: A threefold cross-validation showed that maximum likelihood (ML) estimates of susceptibilities based on individual pathogens gave a distance between estimates obtained from the training set and observed frequencies in the validation set of 16.3%. Estimates based on the initial grouping of pathogens gave a distance of 16.7%. Dirichlet learning gave a distance of 15.6%. Inspection of the pathogen groups led to subdivision of three groups, Citrobacter, Other Gram Negatives and Acinetobacter, out of 26 groups. Estimates based on the subdivided groups gave a distance of 15.4% and Dirichlet learning further reduced this to 15.0%. The optimal size of the imaginary sample inherited from the group was 3.
Conclusion: Dirichlet learning improved estimates of susceptibilities relative to ML estimators based on individual pathogens and to classical grouped estimators. The initial pathogen grouping was well founded and improvement by subdivision of the groups was only obtained in three groups. Dirichlet learning was robust to these revisions of the grouping, giving improved estimates in both cases, while the group-based estimates only gave improved estimates after the revision of the groups.

Abstract
Neutron capture cross sections are among the main inputs for nucleosynthesis network calculations. Although well known for the majority of the stable isotopes, this quantity is still unknown for most of the unstable isotopes of interest. A recent collaboration between ILL, PSI, U. Sevilla and IFIC aims at producing the isotopes of interest at ILL, preparing suitable targets at PSI, and measuring their capture cross sections at facilities such as n_TOF/CERN, LiLiT and the Budapest Research Reactor (BRR). This work is focused on the description of the different beams and techniques and shows some highlights of the preliminary results of the capture measurements on 171Tm, 147Pm and 204Tl, along with the future plans for 79Se and 163Ho.

Abstract
To secure medical devices' management, the implementation of automated dispensing system in surgical service has been realized. The objective of this study was to evaluate security, organizational and economic impact of installing automated dispensing system for medical devices (ASDM). The implementation took place in a cardiac surgery department. Security impact was assessed by comparing traceability rate of implantable medical devices one year before and one year after installation. Questionnaire on nurses' perception and satisfaction completed this survey. Resupplying costs, stocks' evolution and investments for the implementation of ASDM were the subject of cost-benefit study. After one year, traceability rate is excellent (100%). Nursing staffs were satisfied with 87.5% by this new system. The introduction of ASDM allowed a qualitative and quantitative decrease in stocks, with a reduction of 30% for purchased medical devices and 15% for implantable medical devices in deposit-consignment. Cost-benefit analysis shows a rapid return on investment. Real stock decrease (purchased medical devices) is equivalent to 46.6% of investment. Implementation of ASDM allows to secure storage and dispensing of medical devices. This system has also an important economic impact and appreciated by users.

Abstract
BACKGROUND AND PURPOSE Studies of the effects of nicotine on motor symptoms in Parkinson's disease (PD) brought out discordant results. The aim of the present study was to evaluate the efficacy and safety of high doses of transdermal nicotine on motor symptoms in PD. METHODS Forty PD patients were randomly assigned to a treated and untreated arm in an open-label study. Treated patients received increasing doses of nicotine to reach 90 mg/day by 11 weeks. This dosage was maintained for 28 weeks (W39) and then reduced over 6 weeks. Final evaluation was performed 6 weeks after washout. The main outcome measure was the OFF-DOPA Unified Parkinson's Disease Rating Scale (UPDRS) motor score measured on video recordings by raters blinded to the medication status of the patients. RESULTS There was no significant difference in OFF-DOPA UPDRS motor scores between the nicotine-treated and non-treated groups, neither at W39 (19.4 ± 9.3 vs. 21.5 ± 14.2) nor considering W39 differences from baseline (-1.5 ± 12.1 vs. +0.9 ± 12.1). The 39-item Parkinson's disease questionnaire scores decreased in nicotine-treated patients and increased in non-treated patients, but the difference was not significant. Overall tolerability was acceptable, and 12/20 treated patients reached the maximal dosage. CONCLUSIONS High doses of transdermal nicotine were tolerated, but our study failed to demonstrate significant improvement in UPDRS motor scores. Improvement in unblinded secondary outcomes (UPDRS-II, UPDRS-IV, doses of l-DOPA equivalents) suggest a possible benefit for patients treated with nicotine, which should be confirmed in larger double blind, placebo-controlled studies.
