Abstract
We report the prevalence and change in severity of chronic kidney disease (CKD) in DISCOVER, a global, 3-year, prospective, observational study of patients with type 2 diabetes (T2D) initiating second-line glucose-lowering therapy. CKD stages were defined according to estimated glomerular filtration rate (eGFR). Overall, 7843 patients from 35 countries had a baseline serum creatinine measurement. Of these (56.7% male; mean age: 58.1 years; mean eGFR: 87.5 mL/min/1.73 m2 ), baseline prevalence estimates for stage 0-1, 2, 3 and 4-5 CKD were 51.4%, 37.7%, 9.4% and 1.4%, respectively. A total of 5819 patients (74.2%) also had at least one follow-up serum creatinine measurement (median time between measurements: 2.9 years, interquartile range: 1.9-3.0 years). Mean eGFR decreased slightly to 85.7 mL/min/1.73 m2 over follow-up. CKD progression (increase of ≥1 stage) occurred in 15.7% of patients, and regression (decrease of ≥1 stage) in 12.0%. In summary, a substantial proportion of patients with T2D developed CKD or had CKD progression after the initiation of second-line therapy. Renal function should be regularly monitored in these patients, to ensure early CKD diagnosis and treatment.

Abstract
BACKGROUND Information is lacking on long-term management of patients with acute coronary syndrome (ACS) and chronic kidney disease (CKD) (estimated glomerular filtration rate [eGFR] < 60 mL/min/1.73 m2). OBJECTIVES Our objectives were to describe antithrombotic management patterns and outcomes in patients with ACS with varying renal function from the EPICOR (long-tErm follow-uP of antithrombotic management patterns In acute CORonary syndrome patients; NCT01171404) and EPICOR Asia (NCT01361386) studies. METHODS EPICOR and EPICOR Asia were prospective observational studies of patients who survived hospitalization for ACS and were enrolled at discharge in 28 countries across Europe, Latin America, and Asia. The studies were conducted from 2010 to 2013 and from 2011 to 2014, respectively. This analysis evaluated patient characteristics and oral antithrombotic management patterns and outcomes up to 2 years post-discharge according to admission eGFR: ≥ 90, 60-89, 30-59, or < 30 mL/min/1.73 m2. RESULTS Among 22,380 patients with available data, eGFR < 60 mL/min/1.73 m2 was observed in 16.7%. Patients with poorer renal function were older, were at greater cardiovascular risk, and had more prior cardiovascular disease and bleeding. Patients with CKD underwent fewer cardiovascular interventions and had more in-hospital cardiovascular and bleeding events. Dual antiplatelet therapy was less likely at discharge in patients with eGFR < 30 (82.3%) than in those with ≥ 90 (91.3%) mL/min/1.73 m2 and declined more sharply during follow-up in patients with low eGFR (p < 0.0001). An adjusted proportional hazards model showed that patients with lower eGFR levels had a higher risk of cardiovascular events and bleeding. CONCLUSIONS The presence of CKD in patients with ACS was associated with less aggressive cardiovascular management and an increased risk of cardiovascular events.

Abstract
INTRODUCTION Although individualized target glycated hemoglobin (HbA1c) levels are recommended in older people with type 2 diabetes, studies report high levels of potential overtreatment. We aimed to investigate the proportion of older patients (aged ≥65 years) who potentially received an inappropriately intensive treatment (HbA1c level <7.0% (53.0 mmol/mol)) in a global study. Factors associated with intensive glycemic management and using glucose-lowering medications associated with a high risk of hypoglycemia (high-risk medications (insulin, sulfonylureas, and meglitinides)) were also assessed. RESEARCH DESIGN AND METHODS DISCOVER is a 3-year observational study program of 15 992 people with type 2 diabetes initiating second-line glucose-lowering therapy in 38 countries. Data were collected at baseline (initiation of second-line therapy) and at 6, 12, and 24 months. Factors associated with an inappropriately intensive treatment or using high-risk medications were assessed using a hierarchical regression model. RESULTS Of the 3344 older patients with baseline HbA1c data in our analytic cohort, 23.5% received inappropriate treatment intensification. Among those who had follow-up HbA1c data, 55.2%, 54.2%, and 53.5% were inappropriately tightly controlled at 6, 12, and 24 months, respectively, with higher proportions in high-income than in middle-income countries. The proportion of patients receiving high-risk medications was higher in middle-income countries than in high-income countries. Gross national income (per US$5000 increment) was associated with increased odds of inappropriately intensive treatment but with decreased odds of receiving high-risk medications. CONCLUSIONS A large proportion of older DISCOVER patients received an inappropriately intensive glucose-lowering treatment across the 2 years of follow-up, with substantial regional variation. The use of high-risk medications in these patients is particularly concerning.

Abstract
BACKGROUND Studies reporting lower rates of surgery for older women with early invasive breast cancer have focused on women with oestrogen receptor (ER)-positive tumours. This study examined the factors that influence receipt of breast surgery in older women with ER-positive and ER-negative early invasive breast cancer . METHODS Women aged 50 years or above with unilateral stage 1-3A early invasive breast cancer diagnosed in 2014-2017 were identified from linked English and Welsh cancer registration and routine hospital data sets. Logistic regression analysis was used to evaluate the influence of tumour and patient factors on receipt of surgery. RESULTS Among 83 188 women, 86.8 per cent had ER-positive and 13.2 per cent had ER-negative early invasive breast cancer. These proportions were unaffected by age at diagnosis. Compared with women with ER-negative breast cancer, a higher proportion of women with ER-positive breast cancer presented with low risk tumour characteristics: G1 (20.0 versus 1.5 per cent), T1 (60.8 versus 44.2 per cent) and N0 (73.9 versus 68.8 per cent). The proportions of women with any recorded co-morbidity (13.7 versus 14.3 per cent) or degree of frailty (25 versus 25.8 per cent) were similar among women with ER-positive and ER-negative disease respectively. In women with ER-positive early invasive breast cancer aged 70-74, 75-79 and 80 years or above, the rate of no surgery was 5.6, 11.0 and 41.9 per cent respectively. Among women with ER-negative early invasive breast cancer, the corresponding rates were 3.8, 3.7 and 12.3 per cent. The relatively lower rate of surgery for ER-positive breast cancer persisted in women with good fitness. CONCLUSION The reasons for the observer differences should be further explored to ensure consistency in treatment decisions.

Abstract
We evaluated the effectiveness of the ExoMars Raman laser spectrometer (RLS) to determine the degree of serpentinization of olivine-rich units on Mars. We selected terrestrial analogs of martian ultramafic rocks from the Leka Ophiolite Complex (LOC) and analyzed them with both laboratory and flight-like analytical instruments. We first studied the mineralogical composition of the samples (mostly olivine and serpentine) with state-of-the-art diffractometric (X-ray diffractometry [XRD]) and spectroscopic (Raman, near-infrared spectroscopy [NIR]) laboratory systems. We compared these results with those obtained using our RLS ExoMars Simulator. Our work shows that the RLS ExoMars Simulator successfully identified all major phases. Moreover, when emulating the automatic operating mode of the flight instrument, the RLS ExoMars Simulator also detected several minor compounds (pyroxene and brucite), some of which were not observed by NIR and XRD (e.g., calcite). Thereafter, we produced RLS-dedicated calibration curves (R2 between 0.9993 and 0.9995 with an uncertainty between ±3.0% and ±5.2% with a confidence interval of 95%) to estimate the relative content of olivine and serpentine in the samples. Our results show that RLS can be very effective in identifying serpentine, a scientific target of primary importance for the potential detection of biosignatures on Mars-the main objective of the ExoMars rover mission.

Abstract
Aims Heart failure (HF) is increasingly recognized as a major cause of morbidity and mortality in patients with type 2 diabetes (T2D), but the global epidemiology and treatment of HF in T2D are not well defined. This study aimed to examine the global prevalence of HF and the incidence of HF over 3 years of follow‐up in patients with T2D [by presence and absence of co‐existing coronary artery disease (CAD)]. Methods and results DISCOVER was a 3 year, prospective, observational study of T2D patients enrolled at initiation of second‐line glucose‐lowering therapy. Among 14 057 patients with T2D from 36 countries, 289 (2.1%) had a diagnosis of HF at enrolment; median prevalence across countries was 2.0% (inter‐quartile range 1.0–3.1%). Patients with HF at baseline were more likely to be older [HF vs. no HF: 67 ± 12 vs. 57 ± 12 years, standardized difference (StDiff) = 84%] and have longer duration of T2D (8.1 ± 7.2 vs. 5.6 ± 5.2 years, StDiff = 40%), CAD (44% vs. 6%, StDiff = 97%), atrial fibrillation (21% vs. 1%, StDiff = 66%), and kidney disease (23% vs. 4%, StDiff = 55%). Patients with HF were less likely to be on metformin (66% vs. 79%, StDiff = 28%) and thiazolidinediones (5.5% vs. 10.6%, StDiff = 19%) but had similar use of other glucose‐lowering medications. Among 9313 patients with follow‐up data, there were 70 incident cases of HF, which translates to an incidence of 2.6 cases per 1000 person years. Of these incident HF cases, 60% occurred in the absence of pre‐existing or concomitant CAD, and 73% were diagnosed in the outpatient setting. Conclusions In a large, global cohort of patients with T2D, the majority of incident cases of HF occurred in outpatients and in the absence of known CAD. These findings highlight the need for greater awareness of HF risk in patients with T2D.

Abstract
In this work, the analytical research performed by the Raman Laser Spectrometer (RLS) team during the ExoFiT trial is presented. During this test, an emulator of the Rosalind Franklin rover was remotely operated at the Atacama Desert in a Mars-like sequence of scientific operations that ended with the collection and the analysis of two drilled cores. The in-situ Raman characterization of the samples was performed through a portable technology demonstrator of RLS (RAD1 system). The results were later complemented in the laboratory using a bench top RLS operation simulator and a X-Ray diffractometer (XRD). By simulating the operational and analytical constraints of the ExoMars mission, the two RLS representative instruments effectively disclosed the mineralogical composition of the drilled cores (k-feldspar, plagioclase, quartz, muscovite and rutile as main components), reaching the detection of minor phases (e.g., additional phyllosilicate and calcite) whose concentration was below the detection limit of XRD. Furthermore, Raman systems detected many organic functional groups (–C≡N, –NH2 and C–(NO2)), suggesting the presence of nitrogen-fixing microorganisms in the samples. The Raman detection of organic material in the subsurface of a Martian analogue site presenting representative environmental conditions (high UV radiation, extreme aridity), supports the idea that the RLS could play a key role in the fulfilment of the ExoMars main mission objective: to search for signs of life on Mars.

Abstract
Antithrombotic drug use for acute coronary syndromes (ACS) varies considerably. The number of antithrombotic drugs (excluding oral anticoagulants) used pre- and in-hospital was recorded in ACS survivors enrolled at hospital discharge in the long-tErm follow-uP of antithrombotic management patterns In acute CORonary syndrome patients (EPICOR) registry ( NCT01171404 ), a prospective cohort study. Among 10,568 patients, the number of antithrombotic drugs used early/patient ranged from 0 to 8 (interquartile range = 3-4). Overall, 250 patients (2.4%) experienced ≥ 1 in-hospital ischemic event and 343 (3.2%) ≥ 1 non-fatal bleeding event. While there was no difference in the rate of ischemic events (p = 0.75 for-trend) according to the number of antithrombotic drugs, a significantly higher incidence of non-fatal bleeds was observed (p < 0.0001 for-trend), with OR = 1.68 (95%CI = 1.51-1.88) per additional antithrombotic drug, which remained after adjustment by patient characteristics. In conclusion, careful balancing of the short-term risks for ischemic and bleeding events should be considered when adding new antithrombotic drugs.

Abstract
Background:
The European Society of Cardiology established a set of quality indicators for the management of acute myocardial infarction. Our aim was to evaluate their degree of attainment, prognostic value and potential use for centre benchmarking in a large international cohort.
Methods:
Quality indicators were extracted from the long-tErm follow-uP of antithrombotic management patterns In acute CORonary syndrome patients (EPICOR) (555 hospitals, 20 countries in Europe and Latin America, 2010–2011) and EPICOR Asia (218 hospitals, eight countries, 2011–2012) registries, including non-ST-segment elevation acute myocardial infarction (n=6558) and ST-segment elevation acute myocardial infarction (n=11,559) hospital survivors. The association between implementation rates for each quality indicator and two-year adjusted mortality was evaluated using adjusted Cox models. Composite quality indicators were categorized for benchmarking assessment at different levels.
Results:
The degree of attainment of the 17 evaluated quality indicators ranged from 13% to 100%. Attainment of most individual quality indicators was associated with two-year survival. A higher compliance with composite quality indicators was associated with lower mortality at centre-, country- and region-level. Moreover, the higher the risk for two-year mortality, the lower the compliance with composite quality indicators.
Conclusions:
When EPICOR and EPICOR Asia were conducted, the European Society of Cardiology quality indicators would have been attained to a limited extent, suggesting wide room for improvement in the management of acute myocardial infarction patients. After adjustment for confounding, most quality indicators were associated with reduced two-year mortality and their prognostic value should receive further attention. The two composite quality indicators can be used as a tool for benchmarking either at centre-, country- or world region-level.

Abstract
This work aims to evaluate whether the multi-point analysis the ExoMars Raman Laser Spectrometer (RLS) will perform on powdered samples could serve to classify ultramafic rocks on Mars. To do so, the RLS ExoMars Simulator was used to study terrestrial analogues of Martian peridotites and pyroxenites by applying the operational constraints of the Raman spectrometer onboard the Rosalind Franklin rover. Besides qualitative analysis, RLS-dedicated calibration curves have been built to estimate the relative content of olivine and pyroxenes in the samples. These semi-quantitative results, combined with a rough estimate of the concentration ratio between clino- and ortho-pyroxene mineral phases, were used to classify the terrestrial analogues. XRD data were finally employed as reference to validate Raman results. As this preliminary work suggests, ultramafic rocks on Mars could be effectively classified through the chemometric analysis of RLS data sets. After optimization, the proposed chemometric tools could be applied to the study of the volcanic geological areas detected at the ExoMars landing site (Oxia Planum), whose mineralogical composition and geological evolution have not been fully understood.

Abstract
Background:Cardiovascular morbidity and mortality is increased in patients with rheumatoid arthritis (RA). This cannot be entirely explained by traditional risk factors. Inflammation and autoimmunity may play a role in the cardiovascular risk excess. Subclinical atherosclerosis is associated with a risk comparable to established coronary heart disease. In RA it has been investigated by carotid artery ultrasound and carotid atherosclerotic plaques are more prevalent in RA patients than controls. EULAR recommendations for cardiovascular disease risk management consider that carotid ultrasound may be part of the risk evaluation in patients with RA. Recent studies in general population have shown that plaques in femoral arteries are more common and are associated with higher cardiovascular risk.Objectives:To study the usefulness of femoral artery ultrasound for the detection of subclinical atherosclerosis and its ability to improve cardiovascular risk assessment in RA patients.Methods:Cross-sectional observational study of prevalence in 140 RA patients aged 40 to 65 years. Subclinical atherosclerosis was evaluated by carotid and femoral artery ultrasound.Results:Atherosclerotic plaques were found in 86.4% of RA patients (60.7% in carotid arteries and 78.6% in femoral arteries). Patients with plaques were older and more frequently past or present tobacco users. Femoral plaques were larger and more numerous than the carotid plaques and people with plaques in both locations had more extensive subclinical atherosclerotic disease (table). Only 7.9% of RA patients were considered as having very high cardiovascular risk by clinical factors, after carotid ultrasound this increased to 57.1% and after femoral ultrasound to 86.4%.Conclusion:Ultrasound examinations of the femoral artery in addition to the carotid artery increased the detection of subclinical atherosclerosis and determine a group of patients with higher intensity of atherosclerotic disease. Examinations of both arteries allowed a greater number of RA patients previously considered to have low to moderate cardiovascular risk to be classified as very high cardiovascular risk.References:[1]Agca R, Heslinga SC, Rollefstad S, Heslinga M, McInnes IB, Peters MJL, et al.

Abstract
BACKGROUND AND OBJECTIVE Corticosteroid injection is an effective treatment for trigger digits but the pain during the injection is an ever-present side effect. Since the palmar skin has a high density of sensitive receptors, injecting through dorsal skin could be less painful. Our aim was to assess whether a dorsal technique through the dorsal web is safe for extra-sheath injection of trigger fingers and thumb. MATERIAL AND METHOD This is an anatomical study in sixteen cadaveric hands. An injection through the dorsal web was performed on each digit. After careful resection of the palmar skin, the distance between the needle and the main anatomical structures was measured. The risk of major injury was considered high when the mean distance from the needle to the neurovascular bundle was below 1mm. RESULTS The mean distance from the needle to the neurovascular bundle was 1.77mm. Two neurovascular injuries in 112 injections were observed, one nerve and one artery. The safest digit was the thumb while the most dangerous was the index finger. At the ring finger, the technique was safer when it was carried out from the dorso-radial. CONCLUSIONS A subcutaneous injection near the flexor tendon sheath can be carried out through the dorsal web with a low, but present, risk of neurovascular injury. It could be useful for injection in the treatment of trigger finger and trigger thumb but it should be assessed in a clinical study.

Abstract
The aim of the European Space Agency's ExoMars rover mission is to search for potential traces of present or past life in the swallow subsurface (2 m depth) of Mars. The ExoMars rover mission relies on a suite of analytical instruments envisioned to identify organic compounds with biological value (biomarkers) associated with a mineralogical matrix in a highly oxidative environment. We investigated the feasibility of detecting basic organics (linear and branched lipid molecules) with Raman laser spectroscopy, an instrument onboard the ExoMars rover, when exposed to oxidant conditions. We compared the detectability of six lipid molecules (alkanes, alkanols, fatty acid, and isoprenoid) before and after an oxidation treatment (15 days with hydrogen peroxide), with and without mineral matrix support (amorphous silica rich vs. iron rich). Raman and infrared spectrometry was combined with gas chromatography-mass spectrometry to determine detection limits and technical constraints. We observed different spectral responses to degradation depending on the lipid molecule and mineral substrate, with the silica-rich material showing better preservation of organic signals. These findings will contribute to the interpretation of Raman laser spectroscopy results on cores from the ExoMars rover landing site, the hydrated silica-enriched delta fan on Cogoon Vallis (Oxia Planum).

Abstract
SuperCam is a highly integrated remote-sensing instrumental suite for NASA's Mars 2020 mission. It consists of a co-aligned combination of Laser-Induced Breakdown Spectroscopy (LIBS), Time-Resolved Raman and Luminescence (TRR/L), Visible and Infrared Spectroscopy (VISIR), together with sound recording (MIC) and high-magnification imaging techniques (RMI). They provide information on the mineralogy, geochemistry and mineral context around the Perseverance Rover. The calibration of this complex suite is a major challenge. Not only does each technique require its own standards or references, their combination also introduces new requirements to obtain optimal scientific output. Elemental composition, molecular vibrational features, fluorescence, morphology and texture provide a full picture of the sample with spectral information that needs to be co-aligned, correlated, and individually calibrated. The resulting hardware includes different kinds of targets, each one covering different needs of the instrument. Standards for imaging calibration, geological samples for mineral identification and chemometric calculations or spectral references to calibrate and evaluate the health of the instrument, are all included in the SuperCam Calibration Target (SCCT). The system also includes a specifically designed assembly in which the samples are mounted. This hardware allows the targets to survive the harsh environmental conditions of the launch, cruise, landing and operation on Mars during the whole mission. Here we summarize the design, development, integration, verification and functional testing of the SCCT. This work includes some key results obtained to verify the scientific outcome of the SuperCam system.

Abstract
We present the compositional analysis of three terrestrial analogues of Martian olivine-bearing rocks derived from both laboratory and flight-derived analytical instruments. In the first step, state-of-the-art spectroscopic (XRF, NIR and Raman) and diffractometric (XRD) laboratory systems were complementary used. Besides providing a detailed mineralogical and geochemical characterization of the samples, results comparison shed light on the advantages ensured by the combined use of Raman and NIR techniques, being these the spectroscopic instruments that will soon deploy (2021) on Mars as part of the ExoMars/ESA rover payload. In order to extrapolate valuable indicators of the mineralogical data that could derive from the ExoMars/Raman Laser Spectrometer (RLS), laboratory results were then compared with the molecular data gathered through the RLS ExoMars Simulator. Beside correctly identifying all major phases (feldspar, pyroxene and olivine), the RLS ExoMars Simulator confirmed the presence of additional minor compounds (i.e. hematite and apatite) that were not detected by complementary techniques. Furthermore, concerning the in-depth study of olivine grains, the RLS ExoMars simulator was able to effectively detect the shifting of the characteristic double peak around 820 and 850 cm-1, from which the FeMg content of the analyzed crystals can be extrapolated. Considering that olivine is one of the main mineral phases of the ExoMars landing site (Oxia Planum), this study suggests that the ExoMars/RLS system has the potential to provide detailed information about the elemental composition of olivine on Mars.
