Abstract
BACKGROUND Transfers of nursing home (NH) residents to the emergency department (ED) is frequent. Our main objective was to assess the cost of care pathways 6 months before and after the transfer to the emergency department among NH residents, according to the type of transfer (i.e. appropriate or inappropriate). METHODS This was a part of an observational, multicenter, case-control study: the Factors associated with INappropriate transfer to the Emergency department among nursing home residents (FINE) study. Sixteen public hospitals of the former Midi-Pyrénées region participated in recruitment, in 2016. During the inclusion period, all NH residents arriving at the ED were included. A pluri-disciplinary team categorized each transfer to the ED into 2 groups: appropriate or inappropriate. Direct medical and nonmedical costs were assessed from the French Health Insurance (FHI) perspective. Healthcare resources were retrospectively gathered from the FHI database and valued using the tariffs reimbursed by the FHI. Costs were recorded over a 6-month period before and after transfer to the ED. Other variables were used for analysis: sex, age, Charlson score, season, death and presence inside the NH of a coordinating physician or a geriatric nursing assistant. RESULTS Among the 1037 patients initially included in the FINE study, 616 who were listed in the FHI database were included in this economic study. Among them, 132 (21.4%) had an inappropriate transfer to the ED. In the 6 months before ED transfer, total direct costs on average amounted to 8,145€ vs. 6,493€ in the inappropriate and appropriate transfer groups, respectively. In the 6 months after ED transfer, they amounted on average to 9,050€ vs. 12,094€. CONCLUSIONS Total costs on average are higher after transfer to the ED, but there is no significant increase in healthcare expenditure with inappropriate ED transfer. Support for NH staff and better pathways of care could be necessary to reduce healthcare expenditures in NH residents. TRIAL REGISTRATION clinicaltrials.gov, NCT02677272.

Abstract
Despite the well-documented health benefits of the probiotic Saccharomyces, its application in oral health has not been comprehensively assessed. Dental caries is a transmissible disease initiated by acid production of cariogenic bacteria and yeast, such as Streptococcus mutans and Candida albicans, on tooth enamel and followed by subsequent enamel demineralization. Here, we investigated the effect of two Saccharomyces strains (Saccharomyces boulardii and Saccharomyces cerevisiae) on S. mutans-C. albicans cross-kingdom interactions using a cariogenic planktonic model. Viable cells, pH changes, and gene expression were measured. S. cerevisiae and S. boulardii inhibited the growth of C. albicans in dual- and multi-species conditions at 4, 6, and 20 h. Saccharomyces also inhibited C. albicans hyphal formation. Furthermore, Saccharomyces reduced the acidity of the culture medium, which usually plummeted below pH 5 when S. mutans and C. albicans were present in the model. The presence of Saccharomyces maintained the culture medium above 6 even after overnight incubation, demonstrating a protective potential against dental enamel demineralization. S. boulardii significantly down-regulated S. mutans atpD and eno gene expression. Overall, our results shed light on a new promising candidate, Saccharomyces, for dental caries prevention due to its potential to create a less cariogenic environment marked by a neutral pH and reduced growth of C. albicans.

Abstract
OBJECTIVE To compare adnexectomy by vaginal Natural Orifice Transluminal Endoscopic Surgery (vNOTES) versus laparoscopy. DESIGN Parallel group, 1:1 single-centre single-blinded randomised trial, designed as non-inferiority study with a margin of 15%. SETTING Belgian teaching hospital. POPULATION Non-pregnant non-virgin women with an intact uterus and without obliteration of the pouch of Douglas scheduled to undergo removal of an adnexal mass assessed to be benign on ultrasound by IOTA criteria. METHODS Randomisation to laparoscopy (control group) or vNOTES (experimental group). Stratification according to adnexal size. Blinding of participants and outcome assessors by sham incisions. MAIN OUTCOME MEASURES The primary outcome measure was adnexectomy by the allocated technique. Secondary outcomes included duration of surgery, pain scores and analgesics used, quality of life and adverse events. RESULTS We randomly assigned 67 participants (34 to the vNOTES group and 33 to the laparoscopy group). The primary end point was always reached in both groups: there were no conversions. We performed a sensitivity analysis for the primary outcome, assuming one conversion in the vNOTES group and no conversions in the laparoscopy group: the one-sided 95% upper limit for the differences in proportions of conversion was estimated as 13%, which is below the predefined non-inferiority margin of 15%. The secondary outcomes demonstrated a shorter duration of surgery, lower pain scores, lower total dose of analgesics and a trend for more adverse events in the vNOTES group. CONCLUSIONS vNOTES is non-inferior to laparoscopy for a successful adnexectomy without conversion. vNOTES allowed shorter operating times and less postoperative pain but there was a trend for more adverse events.

Abstract
INTRODUCTION Genitourinary menopause syndrome (SGUM) is defined as a set of symptoms associated with a decrease of estrogen and other sexual steroids during menopause. The main symptoms are vulvovaginal (dryness, burning, itching), sexual (dyspareunia), and urinary (urinary infections, pollakiuria, nycturia, pain, urinary incontinence by urgenturia). SGUM leads to an alteration of the quality of life, and affects especially women's sexuality. OBJECTIVE The objective of this review was to elaborate guidelines for clinical practice regarding the management of SGUM in postmenopausal women, and in particular, in women with a history of breast cancer, treated or not with hormone therapy. MATERIALS AND METHODS A systematic review of the literature on SGUM management was conducted on Pubmed, Medline and Cochrane Library. Recommendations from international scholarly societies were also taken into account: International Menopause Society (IMS) https://www.imsociety.org, The North American Menopause Society (NAMS) https://www.menopause.org, Canadian Menopause Society https://www.sigmamenopause.com, European Menopause and Andropause Society (EMAS) https://www.emas-online.org, International Society for the Study of Women's Sexual Health (ISSWSH) https://www.isswsh.org. RESULTS Vaginal use of lubricants, moisturizers and hyaluronic acid improves the symptoms of SGUM and may be offered to all patients. For postmenopausal women, local estrogen will be preferred to the oral route because of their safety and efficacy on all symptoms of SGUM during low-dose use. Prasterone is a local treatment that can be proposed as an effective alternative for the management of dyspareunia and sexual function disorder. Current data on oral testosterone, tibolone, oral or transdermal DHEA and herbal medicine are currently limited. Ospemifène, which has shown a significant improvement in sexual symptoms, is not currently marketed in France. In the particular case of women with a history of breast cancer, non-hormonal regimens are a first-line therapy. Current data on the risk of breast cancer recurrence when administering low-dose local estrogen are reassuring but do not support a conclusion that this treatment is safe. CONCLUSION SGUM is a common symptom that can affect the quality of life of postmenopausal women. A treatment should be systematically proposed. Local non-hormonal treatment may be offered in all women. Local low-dose estrogen therapy and Prasterone has shown an interest in the management of symptoms. In women before a history of breast cancer, local non-hormonal treatment should be offered first-line. The safety of low-dose local estrogen therapy and Prasterone cannot be established at this time. Other alternatives exist but are not currently recommended in France due to lack of data.

Abstract
Achieving optimal blood glucose control in Type 1 diabetes is a delicate balance between ensuring tight glycaemic control and achieving this without the expense of hypoglycaemia and weight gain, two major factors impacting quality of life. This is a real challenge for people with Type 1 diabetes and underpins many of the struggles they face in self-managing on a day-to-day basis. The main goals of insulin delivery are to try to simulate the physiology of β-cell insulin secretion as closely as possible and to overcome the challenges of peripheral insulin administration by achieving rapidity of onset with mealtime insulins and stability of the glucose-lowering effects of long-acting insulins. Since the early days of human insulin use, there have been many developments in insulin formulations that aim to achieve these goals as much as possible, thus contributing to better glycaemic control whilst minimizing hypoglycaemia. In the present review we discuss the currently available insulin analogues and the challenges of achieving glucose control using current analogues in those on multiple daily injections, and appraise the evidence base for newer-generation insulin analogues, such as insulin degludec, glargine U300, faster-acting insulin aspart and BioChaperone lispro. We also highlight new insulins in development and unmet needs in people with Type 1 diabetes.

Abstract
The European General Data Protection Regulation (GDPR) has dotted the i's and crossed the t's in the context of academic medical research. One year into GDPR, it is clear that a change of mind and the uptake of new procedures is required. Research organisations have been looking at the possibility to establish a code-of-conduct, good practices and/or guidelines for researchers that translate GDPR's abstract principles to concrete measures suitable for implementation. We introduce a proposal for the implementation of GDPR in the context of academic research which involves the processing of health related data, as developed by a multidisciplinary team at the University Hospitals Leuven. The proposal is based on three elements, three stages and six specific safeguards. Transparency and pseudonymisation are considered key to find a balance between the need for researchers to collect and analyse personal data and the increasing wish of data subjects for informational control.

Abstract
Introduction: Limiting the number of dependent older people in coming years will be a major economic and human challenge. In response, the World Health Organization (WHO) has developed the «Integrated Care for Older People (ICOPE)» approach. The aim of the ICOPE program is to enable as many people as possible to age in good health. To reach this objective, the WHO proposes to follow the trajectory of an individual’s intrinsic capacity, which is the composite of all their physical and mental capacities and comprised of multiple domains including mobility, cognition, vitality / nutrition, psychological state, vision, hearing. Objective: The main objective of the INSPIRE ICOPE-CARE program is to implement, in clinical practice at a large scale, the WHO ICOPE program in the Occitania region, in France, to promote healthy aging and maintain the autonomy of seniors using digital medicine. Method: The target population is independent seniors aged 60 years and over. To follow this population, the 6 domains of intrinsic capacity are systematically monitored with pre-established tools proposed by WHO especially STEP 1 which has been adapted in digital form to make remote and large-scale monitoring possible. Two tools were developed: the ICOPE MONITOR, an application, and the BOTFRAIL, a conversational robot. Both are connected to the Gerontopole frailty database. STEP 1 is performed every 4-6 months by professionals or seniors themselves. If a deterioration in one or more domains of intrinsic capacity is identified, an alert is generated by an algorithm which allows health professionals to quickly intervene. The operational implementation of the INSPIRE ICOPE-CARE program in Occitania is done by the network of Territorial Teams of Aging and Prevention of Dependency (ETVPD) which have more than 2,200 members composed of professionals in the medical, medico-social and social sectors. Targeted actions have started to deploy the use of STEP 1 by healthcare professionals (physicians, nurses, pharmacists,…) or different institutions like French National old age insurance fund (CNAV), complementary pension funds (CEDIP), Departmental Council of Haute Garonne, etc. Perspective: The INSPIRE ICOPE-CARE program draws significantly on numeric tools, e-health and digital medicine to facilitate communication and coordination between professionals and seniors. It seeks to screen and monitor 200,000 older people in Occitania region within 3 to 5 years and promote preventive actions. The French Presidential Plan Grand Age aims to largely implement the WHO ICOPE program in France following the experience of the INSPIRE ICOPE-CARE program in Occitania.

Abstract
Insulin degludec (Tresiba®) is characterized by an original mode of prolonged and continuous insulin release after its subcutaneous injection. Thereby, it has a very long glucose-lowering effect, around 42 hours, and a better reproducibility from both a pharmacokinetic and pharmacodynamic point of view. Its efficacy and safety have been assessed in the phase 3 clinical programme BEGIN as compared with insulin glargine U100, in patients with type 1 diabetes (T1D) and type 2 (T2D). For a similar glucose control (reduction in glycated haemoglobin), less hypoglycaemic episodes were recorded, including severe hypoglycaemia, during the nocturnal period, with insulin degludec than with insulin glargine U100. This clinical benefit has been confirmed in the complementary SWITCH programme in T1D and T2D patients at higher risk of hypoglycaemia, in the double-blind cardiovascular outcome trial DEVOTE in T2D patients at high cardiovascular risk and in real-life conditions in the observational European EU-TREAT study in patients with T1D and T2D. Insulin degludec (Tresiba®) is indicated and reimbursed for the treatment of patients with T1D, combined with a prandial insulin, and T2D, alone or combined with oral antidiabetic agents, a glucagon-like peptide-1 receptor agonist or a short-acting insulin.

Abstract
A new (N2H4)WO3 compound has been obtained by mixing WO3 and aqueous hydrazine solution at room temperature for 24 h. The reaction is catalyzed by the presence of lithium. X-ray, synchrotron and neutron diffraction techniques have shown that the material crystallizes in trigonal space group P3221 (No. 154). Chains of distorted WO4 tetrahedra extend along the a axis of the unit cell, linked by a corner-sharing oxygen atom: the N2H4 are in the voids between them. The thermal characterization shows that this new compound is stable up to 220°C, greatly beyond the boiling point of N2H4 (114°C); thus making it a promising candidate for catalysis or trapping applications.

Abstract
Essentials Neutrophil extracellular traps (NETs) are generated during deep vein thrombosis (DVT). The role of interferon γ (IFNγ) and natural killer (NK) cells in NET formation was studied. IFNγ promote venous thrombosis through NET formation. NK cell depletion reduces DVT. SUMMARY: Background Neutrophils contribute to venous thrombosis through the release of neutrophil extracellular traps (NETs), but the mechanism triggering their formation remains unclear. In vitro data show that interferon (IFN)-γ induces the formation of NETs. Objectives To determine whether IFN-γ and the transcription factor T-box expressed on T cells (Tbet) promote venous thrombosis through neutrophil activation. Methods Venous thrombosis was induced by flow restriction in the inferior vena cava in IFN-γ-/- , Tbet-/- or wild-type (WT) mice. After 48 h, thrombus size was measured by the use of high-frequency ultrasound. NET formation was determined by immunofluorescence. Results and Conclusions Thrombus formation was reduced in Tbet-/- and IFN-γ-/- mice, suggesting that Tbet/IFN-γ-expressing cells are required for venous thrombosis. The number of NETs formed during thrombosis was significantly lower in Tbet-/- and IFN-γ-/- mice. NET formation was also decreased in WT mice treated with an IFN-γ-blocking antibody. Injection of recombinant IFN-γ into IFN-γ-/- mice rescued the phenotype. Natural killer (NK) cells were specifically depleted prior to venous thrombosis induction. NK cell depletion results in decreased NET formation and smaller thrombi, suggesting that NK cells are required for thrombus development. In depleted mice, adoptive transfer of WT NK cells induced a similar thrombosis burden as in WT mice. In contrast, adoptive transfer of IFN-γ -/- NK cells resulted in thrombi similar in size to those in depleted mice. In vitro, we showed that WT neutrophils released fewer NETs when they were cocultured with IFN-γ-/- NK cells. This study demonstrates that NK cell-dependent IFN-γ production is crucial for thrombus development by promoting the formation of NETs by neutrophils.

Abstract
Xultophy® (IDegLira) is a fixed ratio combination of basal insulin degludec and glucagon-like peptide-1 (GLP-1) receptor agonist liraglutide. Insulin degludec is characterized by an original mode of prolonged and continuous insulin diffusion after its subcutaneous injection. Thereby, it has a very long half-life, around 25 hours, and a better reproducibility from both a pharmacokinetic and pharmacodynamic point of view, with less hypoglycaemia, especially at night. Liraglutide is a well-known once-daily GLP-1 receptor agonist that showed a cardiovascular and renal protection in patients with type 2 diabetes at high cardiovascular risk. Both molecules exert complementary antihyperglycaemic effects, which allows a better glucose control, both in the fasting and postprandial states. IDegLira is more effective than another basal insulin regimen in reaching individualized glycated haemoglobin target, with a lower daily dose of insulin. It has a better tolerance profile, with a more favourable effect on body weight and less hypoglycaemia compared with a basal insulin and less gastrointestinal adverse effects when compared with liraglutide alone. Xultophy® is presented as a prefilled pen and is indicated in the management of type 2 diabetes not well controlled with basal insulin. The dose of IDegLira is progressively uptitrated, starting from 16 dose steps up to a maximum of 50 dose steps per day (corresponding to 50 IU insulin degludec and 1.8 mg liraglutide).

Abstract
We have used energy-filtered photoemission electron microscopy (PEEM) at the photoemission threshold to carry out a microscopic scale characterization of the surface charge and domain structure of the (001) surface in BaTiO3. Signatures of ferroelectric and ferroelastic domains, and tweed, dominate the surface structure of BaTiO3 at room temperature. The surface ferroic signatures are maintained on heating to temperature (~550 K), well above the transition temperature (393 K). This surface proximity effect provides the mechanism for memory of the bulk ferroelectric domain arrangement up to 150 K above TC and thus can be considered as a robust fingerprint of the ferroelectric state near the surface. Self-reversal of polarization is observed for the tweed below TC and for the surface domains above TC. Annealing at higher temperature triggers the dynamic tweed which in turn allows a full reorganization of the ferroic domain configuration.

Abstract
INTRODUCTION Moulds and mite allergens present in indoor environments are well known for their effects on respiratory health. METHODS From 2011 to 2015, the Paris Service for Environmental Health (SPSE) conducted investigations in 293 dwellings following medical referral. These audits included fungal analysis of air (in 12% of dwellings), in mattress surface and floor dust (24%), and mite allergen quantifications in mattresses and carpets (18%). RESULTS Indoor air fungal concentrations are not significantly different from those in outdoor air. When there is no ventilation or when the system is malfunctioning, an increase in indoor/outdoor air ratios is observed, indicating mould enrichment in the dwelling's indoor air. With regard to house dust samples, fungal spore concentrations vary according to the media from which samples were collected. Mattress fungal contamination is higher in dwellings where observed surface moulds exceed 1 per square meter. In the same way Der p1 mite allergens levels are greater in mattress dust in dwellings where mould contamination is visible. CONCLUSIONS This study describes the levels of contamination in the dwellings of Parisian patients.

Abstract
In vitro studies using plant extracts suggest a relationship between their polyphenol contents and their anthelmintic (AH) activity against Haemonchus contortus. High polyphenol content appears to increase the efficacy of plant extracts against H. contortus as assessed by the larval exsheathment inhibition assay (LEIA) while appearing to reduce the AH efficacy measured using the egg hatch assay (EHA). In addition, some plants lack AH activity. Therefore, the present study investigated the relationship between the contents of condensed tannins (CT), total phenols (TP), and total tannins (TT) in methanol:water extracts (70:30) obtained from ten tropical plant species consumed by small ruminants as well as their AH activity against H. contortus evaluated by LEIA and EHA. Extracts of Acacia collinsii, Lysiloma latisiliquum, Havardia albicans, Senegalia gaumeri, Mimosa bahamensis, Piscidia piscipula, Acacia pennatula, Gymnopodium floribundum, Leucaena leucocephala, and Bunchosia swartziana were examined. Positive correlations were found between the effective concentration 50% (EC50) (EHA) of extracts and their CT (r = 0.6809, P < 0.05, n = 10) and TP (r = 0.9152, P < 0.05, n = 10) content, suggesting that their concentration negatively affected AH activity against eggs. Based on the LEIA, there was no significant association between the EC50 and the CT, TP, or TT of all extracts evaluated. Thus, if sheep and goats consume a complex feed mixture with high amounts of CT, TP, and TT, it might be difficult to observe an AH effect against H. contortus egg hatching. However, the AH effect upon L3 establishment might be feasible.

Abstract
Regulatory approval of the first biosimilar insulin in Europe, LY2963016 insulin glargine (Abasaglar® ), in 2014 expanded the treatment options available to people with diabetes. As biosimilar insulin products come to market, it is important to recognize that insulin products are biologicals manufactured through complex biotechnology processes, and thus biosimilar insulins cannot be considered identical to their reference products. Strict regulatory guidelines adopted by authorities in Europe, the USA and some other countries help to ensure that efficacy and safety profiles of biosimilar insulins are not meaningfully different from those of the reference products, preventing entry of biological compounds not meeting quality standards and potentially affecting people's glycaemic outcomes. This review explains the concept of biosimilar medicines and outlines regulatory requirements for registration of biosimilar insulins in Europe, which is illustrated by the successful development of LY2963016 insulin glargine and MK-1293 insulin glargine (Lusduna® ). Preclinical and clinical comparative studies of the biosimilar insulin glargine programmes include in vitro bioassays for insulin and insulin-like growth factor 1 receptor binding, assessment of in vitro biological activity, evaluation of pharmacokinetic/pharmacodynamic profiles in phase I studies and assessment of long-term safety and efficacy in phase III studies. The emergence of biosimilar insulins may help broaden access to modern insulins, increase individualized treatment options and reduce costs of insulin therapy.

Abstract
Diabetes mellitus imposes a significant and increasing burden on society, with major consequences for human health, welfare and the economy worldwide. Persons with diabetes mellitus are at increased risk of developing severe complications after influenza virus infection and guidelines advise vaccination. The present evidence for influenza vaccine effectiveness in persons with diabetes mellitus is mainly based on observational studies with clinical endpoints like hospitalization and death, indicating a beneficial reduction of morbidity and mortality. Further supportive evidence comes from serological studies, in which persons with diabetes mellitus usually develop similar antibody levels after vaccination as healthy people. Observational studies may be prone to selection bias, and serological studies may not completely mirror vaccine effectiveness in the field. Although more controlled trials in persons with diabetes mellitus with laboratory-confirmed, influenza-specific outcomes would be desirable to better estimate the effect of vaccination, the currently available data justify routine influenza vaccination in persons with diabetes mellitus. As in this risk group, the use of influenza vaccine is far below target worldwide, efforts should be made to increase vaccination coverage.

Abstract
The larval exsheathment inhibition assay (LEIA) of infective larvae (L3) is an in vitro method used to evaluate the anthelmintic (AH) activity of tannin-containing plant extracts against different species of gastrointestinal nematodes, including Haemonchus contortus. Some conditions remain to be defined in order to standardize the LEIA, i.e. the optimal age of larvae produced from donor animals to use in the assays. Therefore, this study aimed at identifying the effect of age and age-related vitality of H. contortus infective larvae produced under tropical conditions, on the in vitro AH activity measured with the LEIA. The same acetone:water (70:30) extract from Acacia pennatula leaves was used to perform respective LEIA tests with H. contortus L3 of different ages (1-7 weeks). Each week, the L3 were tested against different concentrations of extract (1200, 600, 400, 200, 100, 40μg/mL of extract) plus a PBS control. Bioassays were performed with a benzimidazole (Bz) resistant H. contortus (Paraíso) strain. In order to identify changes in L3 vitality on different weeks (1-7), two assays testing larval motility were included only with PBS: the larval migration assay (LMA) and the larval motility observation assay (LMOA). Mean effective concentrations causing 50% and 90% exsheathment inhibition (EC50, EC90) were obtained for every week using respective Probit analyses. On the first week, the larvae had lowest EC50 and EC90 (39.4 and 65.6μg/mL) compared to older larvae (P<0.05). The EC50 and EC90 for weeks 2-5 were similar (P>0.05), while older larvae tended to show higher EC50 and EC90 (P<0.05). Motility showed strong negative correlations with age of larvae (r≥-0.83; P <0.05) and EC50 (r≥-0.80; P<0.05), suggesting that the lower extract efficacy could be associated with decaying vitality of larvae associated with age. More stable efficacy results were found between two to five weeks of age.

Abstract
Islet transplantation is a promising treatment in type 1 diabetes, but the need for chronic immunosuppression is a major hurdle to broad applicability. Ex vivo introduction of agents by lentiviral vectors—improving β-cell resistance against immune attack—is an attractive path to pursue. The aim of this study was to investigate whether dissociation of islets to single cells prior to viral infection and reaggregation before transplantation would improve viral transduction efficacy without cytotoxicity. This procedure improved transduction efficacy with a LV-pWPT-CMV-EGFP construct from 11.2 ± 4.1% at MOI 50 in whole islets to 80.0 ± 2.8% at MOI 5. Viability (as measured by Hoechst/PI) and functionality (as measured by glucose challenge) remained high. After transplantation, the transfected pseudoislet aggregates remained EGFP positive for more than 90 days and the expression of EGFP colocalized primarily with the insulin-positive β-cells. No increased vulnerability to immune attack was observed in vitro or in vivo. These data demonstrate that dispersion of islets prior to lentiviral transfection and reaggregation prior to transplantation is a highly efficient way to introduce genes of interest into islets for transplantation purposes in vitro and in vivo, but the amount of β-cells needed for normalization of glycemia was more than eightfold higher when using dispersed cell aggregates versus unmanipulated islets. The high price to pay to reach stable and strong transgene expression in islet cells is certainly an important cell loss.

Abstract
AIM In this post hoc analysis of the EDGE study, we assessed the effectiveness and safety of vildagliptin versus other oral antidiabetes drugs (OADs) as add-on to first-line sulphonylurea (SU) therapy in patients who did not receive metformin in a real-life setting. METHODS The primary endpoint was odds of achieving an HbA1c reduction of >0.3% without tolerability issues. Secondary endpoint was odds of achieving HbA1c <7.0% without hypoglycaemia or weight gain. Changes in HbA1c, body weight; and safety were also assessed. RESULTS 2936 patients received vildagliptin and 820 received comparator OADs (any α-GI, TZD, glinide) as add-on to first-line SU therapy. Overall, the mean age, disease duration, HbA1c, and BMI at baseline were 57.1 years, 6.3 years, 8.5%, and 27.7kg/m2, respectively. The odds ratios for achieving primary and secondary endpoints were 1.6 (95% CI: 1.36, 1.86; p<0.0001) and 1.8 (1.45, 2.21; p<0.0001), respectively, in favour of vildagliptin. The between-treatment differences (vildagliptin vs. comparator OAD) for the mean change in HbA1c and body weight were -0.2±0.04% (p<0.0001) and -0.8±0.16kg (p<0.0001), respectively. Overall, the incidence of adverse events was low (vildagliptin, 7% vs. comparator, 8.2%) in both groups. Similar results were observed in a subset of patients enrolled from India and patients who received TZDs as a comparator OAD. CONCLUSION Under real-life settings, vildagliptin as add-on to SU monotherapy showed better glycaemic response without tolerability issues compared with other OADs.

Abstract
We previously reported that dapagliflozin versus placebo as add-on to saxagliptin plus metformin resulted in greater reductions in glycated haemoglobin (A1C), fasting plasma glucose (FPG) and body weight (BW) after 24 weeks of treatment in patients with type 2 diabetes (T2D). Here we report results after 52 weeks of treatment. Patients stabilized on open-label metformin and saxagliptin 5 mg/day for 8-16 weeks were randomized to placebo or dapagliflozin 10 mg/day plus open-label saxagliptin plus metformin for 52 weeks. Changes from baseline to week 52 were greater with dapagliflozin versus placebo in A1C (-0.74% vs. 0.07%), FPG (-27 vs. 10 mg/dL) and BW (-2.1 vs. -0.4 kg). More patients achieved A1C <7% with dapagliflozin (29.4%) versus placebo (12.6%). Adverse events were similar with dapagliflozin (66%) and placebo (71%), and hypoglycaemia was rare (≤2%). Genital infections occurred more often with dapagliflozin (6%) than with placebo (1%); frequency of urinary tract infections was similar between the two groups (9% vs. 10%). Triple therapy with dapagliflozin add-on to saxagliptin plus metformin is a durable, effective and well-tolerated intervention for the treatment of T2D.

Abstract
The understanding of domain structures, specifically domain walls, currently attracts a significant attention in the field of (multi)-ferroic materials. In this article, we analyze contrast formation in full field electron microscopy applied to domains and domain walls in the uniaxial ferroelectric lithium niobate, which presents a large 3.8 eV band gap and for which conductive domain walls have been reported. We show that the transition from Mirror Electron Microscopy (MEM – electrons reflected) to Low Energy Electron Microscopy (LEEM – electrons backscattered) gives rise to a robust contrast between domains with upwards (Pup) and downwards (Pdown) polarization, and provides a measure of the difference in surface potential between the domains. We demonstrate that out-of-focus conditions of imaging produce contrast inversion, due to image distortion induced by charged surfaces, and also carry information on the polarization direction in the domains. Finally, we show that the intensity profile at domain walls provides experimental evidence for a local stray, lateral electric field.

Abstract
Significant progress in the understanding of surfaces and interfaces of materials for new technologies requires operando studies, i.e., measurement of chemical, electronic, and magnetic properties under external stimulus (such as mechanical strain, optical illumination, or electric fields) applied in situ in order to approach real operating conditions. Electron microscopy attracts much interest, thanks to its ability to determine semiconductor doping at various scales in devices. Spectroscopic photoelectron emission microscopy (PEEM) is particularly powerful since it combines high spatial and energy resolution, allowing a comprehensive analysis of local work function, chemistry, and electronic structure using secondary, core level, and valence band electrons, respectively. Here we present the first operando spectroscopic PEEM study of a planar Si p-n junction under forward and reverse bias. The method can be used to characterize a vast range of materials at near device scales such as resistive oxides, conducting bridge memories and domain wall arrays in ferroelectrics photovoltaic devices.

Abstract
AIMS A prospective meta-analysis of phase 3 trials showed lower rates of nocturnal hypoglycaemia with insulin degludec vs. insulin glargine. We investigated the consistency of the results across different definitions of hypoglycaemia. METHODS This post-hoc, patient-level meta-analysis included six randomized, controlled, 26- or 52-week phase 3a trials in insulin-naïve participants with Type 2 diabetes mellitus (Type 2 diabetesinsulin naïve ), participants with Type 2 diabetes mellitus using basal-bolus therapy (Type 2 diabetesBB ) and those with Type 1 diabetes mellitus. We used three definitions of hypoglycaemia and different timescales for the nocturnal period. Rates were analysed for the entire core trial period, the 'maintenance period' only, and the extension trial set population. Analyses utilized a negative binomial regression model. RESULTS In Type 2 diabetesinsulin naïve participants, risk of nocturnal hypoglycaemia was significantly lower with insulin degludec vs. insulin glargine for all hypoglycaemia definitions and trial periods. Risk was also lower for the timescale 21.59-05.59, but not 00.01-07.59. For Type 2 diabetesBB , nocturnal hypoglycaemia rates were lower with insulin degludec vs. insulin glargine across all definitions, timescales and trial periods, with one exception. For individuals with Type 1 diabetes mellitus, nocturnal hypoglycaemia risk was significantly lower with insulin degludec during the maintenance period for the original definition (plasma glucose < 3.1 mmol/l, timescale 00.01-05.59) and in the extension trial set population for all hypoglycaemia definitions except for the nocturnal timescale 00.01-07.59. CONCLUSIONS Compared with insulin glargine, insulin degludec is associated with lower rates of nocturnal hypoglycaemia in people with Type 2 diabetes mellitus, and similar or lower rates in Type 1 diabetes mellitus, across different definitions.

Abstract
AIMS To assess the efficacy and safety of canagliflozin, a sodium glucose co-transporter 2 (SGLT2) inhibitor, in patients with type 2 diabetes enrolled in the CANagliflozin cardioVascular Assessment Study (CANVAS) who were on an incretin mimetic [dipeptidyl peptidase-4 (DPP-4) inhibitor or glucagon-like peptide-1 (GLP-1) receptor agonist]. METHODS CANVAS is a double-blind, placebo-controlled study that randomized participants to canagliflozin 100 or 300 mg or placebo added to routine therapy. The present post hoc analysis assessed the efficacy and safety of canagliflozin 100 and 300 mg compared with placebo in subsets of patients from CANVAS who were taking background DPP-4 inhibitors or GLP-1 receptor agonists with or without other antihyperglycaemic agents at week 18. RESULTS Of the 4330 patients in CANVAS, 316 were taking DPP-4 inhibitors and 95 were taking GLP-1 receptor agonists. At 18 weeks, canagliflozin 100 and 300 mg provided larger placebo-subtracted reductions in glycated haemoglobin (HbA1c) in patients taking DPP-4 inhibitors [-0.56% (95% confidence interval [CI]: -0.77, -0.35), and -0.75% (95% CI: -0.95, -0.54), respectively] and GLP-1 receptor agonists [-1.00% (95% CI: -1.35, -0.65), and -1.06% (95% CI: -1.43, -0.69), respectively]. Body weight and blood pressure (BP) reductions were seen with canagliflozin versus placebo in both subsets. Higher incidences of genital mycotic infections and osmotic diuresis-related adverse events (AEs) were seen with canagliflozin compared with placebo. The incidence of hypoglycaemia was numerically higher with canagliflozin versus placebo; nearly all events occurred in patients on background insulin or insulin secretagogues. CONCLUSIONS In patients on background incretin mimetics, canagliflozin improved HbA1c, body weight and BP, with an increased incidence of AEs related to SGLT2 inhibition.

Abstract
Initiating or intensifying insulin therapy is often considered as a challenge in general practice. The observational prospective Belgian study InsuStar was performed in 2011-2013 among 150 representative general practitioners, who were invited to initiate or intensify insulin therapy when necessary in 523 patients with type 2 diabetes (mean age: 65.5 years; mean HbAk: 8.8%). The initiation of insulin therapy (glargine in > 50%) was justified by insufficient glycaemic control (96%) and its intensification (replacement of insulin NPH or premixed insulins by insulin glargine, eventually with the addition of a short-acting insulin analogue) aimed at improving glucose control (58%), avoiding hypoglycaemia (17%) or both (17%). After a follow up of 6:1 months, HbAlc level decreased from 8.79% to 7.52% (-1.27%; 95% confidence interval: -1.43, -1.11; p<0.001). Overall 27.6% of patients reached an HbAl, < 7% versus 5.9% at inclusion (p<0.001), with rather few hypoglycaemia and a high physi- cian confidence level regarding insulin therapy. These results should encourage general practitioners to initiate insulin therapy at an earlier stage and to intensify it when necessary in patients with insufficiently controlled type 2 diabetes.
